Original  Borrowers,  the  "Borrowers"  and,  individually,  each a "Borrower"),
jointly and  severally,  each promise to pay to the order of BRIDGE  OPPORTUNITY
FINANCE, LLC (hereinafter, together with any holder hereof, called "Lender"), at
the principal  office of the Lender,  the  principal sum of Ten Million  Dollars
($10,000,000),  or, if less, the aggregate  unpaid  principal amount of all Term
Loans made by Lender to any one or more of the  Borrowers  pursuant  to the Loan
Agreement  (as  hereinafter  defined).  Each  Borrower,  jointly and  severally,
further  promises to pay interest on the outstanding  principal amount hereof on
the  dates and at the  rates  provided  in the Loan  Agreement  (as  hereinafter
defined) from the date hereof until payment in full hereof.

      This Amended and Restated Term Note (this "Note") is delivered pursuant to
that  certain Loan and  Security  Agreement - Term Loan,  dated as of August 31,
2004 as it may be amended from time to time, together with all exhibits thereto,
between  Lender and the Borrowers  (the "Loan  Agreement").  All terms which are
capitalized and used herein (which are not otherwise  defined herein) shall have
the meaning ascribed to such term in the Loan Agreement. This Note is secured by
the  personal  property  described  in and  pursuant to the Loan  Agreement  and
various Loan Documents referred to therein,  and reference is made thereto for a
statement of terms and provisions of such Collateral  security, a description of
Collateral and the rights of Lender in respect thereof.

      Principal  hereunder  shall be payable  pursuant  to the terms of the Loan
Agreement. Upon the occurrence of an Event of Default, the unpaid balance of the
principal  amount of this Note,  together  with all accrued and unpaid  interest
thereon,  may  become,  or may be declared to be, due and payable in the manner,
upon the conditions and with the effect provided in the Loan Agreement.

      Each Borrower  hereby  authorizes the Lender to charge any account of such
Borrower  for all sums due  hereunder.  If  payment  hereunder  becomes  due and
payable  on a day that is not a  Business  Day,  the due date  thereof  shall be
extended to the next  succeeding  Business  Day, and  interest  shall be payable
thereon at the rate specified  during such extension.  Credit shall be given for
payments made in the manner and at the times provided in the Loan Agreement.  It
is the intent of the parties that the rate of interest and other  charges to the
Borrowers  under  this Note shall be  lawful;  therefore,  if for any reason the
interest or other  charges  payable  hereunder are found by a court of competent
jurisdiction,  in a final  determination,  to exceed the limit which  Lender may
lawfully  charge the  Borrowers,  then the  obligation  to pay interest or other
charges  shall  automatically  be reduced  to such  limit and,  if any amount in
excess of such limit shall have been paid, then such amount shall be refunded to
the Borrowers.

<PAGE>

      The  principal  and all accrued  interest  hereunder may be prepaid by the
Borrowers,  in whole,  but not in part, at any time  (subject to any  applicable
prepayment fee).

      Each Borrower waives the benefit of any law that would otherwise  restrict
or limit Lender in the exercise of its right, which is hereby  acknowledged,  to
set-off against the Obligations,  without notice and at any time hereafter,  any
indebtedness  matured or  unmatured  owing from  Lender to the  Borrowers.  Each
Borrower  waives every defense,  counterclaim  or setoff which such Borrower may
now have or hereafter  may have to any action by Lender in  enforcing  this Note
and/or any of the other  Obligations,  or in  enforcing  Lender's  rights in the
Collateral  and  ratifies and  confirms  whatever  Lender may do pursuant to the
terms hereof and of the Loan  Agreement and with respect to the  Collateral  and
agrees that Lender  shall not be liable for any error in judgment or mistakes of
fact or law.

      Each Borrower,  any other party liable with respect to the Obligations and
any and all endorsers and accommodation  parties,  and each one of them, if more
than one, waive any and all presentment,  demand,  notice of dishonor,  protest,
and all other notices and demands in connection with the enforcement of Lender's
rights hereunder.

      The loan  evidenced  hereby has been made and this Note has been delivered
at Chicago, Illinois. THIS NOTE SHALL BE GOVERNED AND CONTROLLED BY THE INTERNAL
LAWS OF THE  STATE OF  ILLINOIS  AS TO  INTERPRETATION,  ENFORCEMENT,  VALIDITY,
CONSTRUCTION,  EFFECT, AND IN ALL OTHER RESPECTS,  INCLUDING WITHOUT LIMITATION,
THE LEGALITY OF THE INTEREST RATE AND OTHER  CHARGES,  and shall be binding upon
the Borrowers and their respective successors and assigns. If this Note contains
any blanks when  executed  by the  Borrowers,  the Lender is hereby  authorized,
without  notice to the  Borrowers to complete  any such blanks  according to the
terms  upon  which  the loan or loans  were  granted.  Wherever  possible,  each
provision  of this Note shall be  interpreted  in such manner as to be effective
and valid  under  applicable  law,  but if any  provision  of this Note shall be
prohibited by or be invalid under such law, such  provision  shall be severable,
and be  ineffective to the extent of such  prohibition  or  invalidity,  without
invalidating the remaining provisions of this Note.

      To  induce  the  Lender  to make the loan  evidenced  by this  Note,  each
Borrower  (i)  irrevocably  agrees that,  subject to Lender's  sole and absolute
election,  all  actions  arising  directly  or  indirectly  as a  result  or  in
consequence  of  this  Note or any  other  agreement  with  the  Lender,  or the
Collateral, shall be instituted and litigated only in courts having situs in the
City of Chicago,  Illinois;  (ii) hereby consents to the exclusive  jurisdiction
and venue of any State or  Federal  Court  located  and having its situs in said

LENDER AND EACH BORROWER  HEREBY WAIVE TRIAL BY JURY IN ANY ACTION OR PROCEEDING
WHICH  PERTAINS  DIRECTLY  OR  INDIRECTLY  TO THIS NOTE,  THE  OBLIGATIONS,  THE
COLLATERAL,  ANY ALLEGED  TORTIOUS CONDUCT BY BORROWER OR LENDER OR WHICH IN ANY
WAY,  DIRECTLY  OR  INDIRECTLY,  ARISES OUT OF OR  RELATES  TO THE  RELATIONSHIP
BETWEEN BORROWER AND LENDER. In addition,  each Borrower agrees that all service
of process shall be made as provided in the Loan Agreement.
