Subject to the terms and conditions of this Agreement and on the basis of

Company's  execution and delivery to the Lender of the Note described in Section
                                                                         -------

The  Loan  shall  be  made  on  the  date  hereof  in  the amount of $2,000,000.

SECTION  3.          TERMS  OF  THE  LOAN

     3.1     The  Note.
             ---------
The  obligation of the Company to repay the aggregate unpaid principal amount
of the  Loan  and  fees  due  under  this  Agreement  shall  be  evidenced  by
a  promissory  note  or  notes  in  the  form  attached  hereto  as
Exhibit  B  (the  "Note"),  dated  the date hereof, payable as specified in this
----------         ----
Section  3,  made  to  the  order  of  the Lender or any subsequent Holder in an
----------
aggregate  principal  amount of $2,450,000, and bearing interest and maturing as
provided  in  this  Agreement.

     3.2     Interest  on  the  Loan.
             -----------------------
     3.2.1.     The Loan shall bear interest at a rate equal to 18% per annum on
the  unpaid  principal  amount  thereof  (including  Capitalized  Interest,  as
hereafter  defined)  from  and  including  the  Closing Date until the principal
amount  shall  be paid in full, such interest shall be paid by capitalizing such
interest  as  additional  Loans  on  the  applicable  Interest  Payment  Date
("Capitalized  Interest"),  and  any  interest  that  is to be capitalized shall
  ---------------------
accrue  interest at a rate that is equal to 18%.  Notwithstanding the foregoing,
upon the occurrence of an Event of Default hereunder and for so long as an Event
of  Default  is continuing, the interest rate to the extent permitted by law, on
the  unpaid  principal  amount  of  the  Loan  shall  be  20%.

     3.2.2.     Interest  shall  be  capitalized  with  respect  to the Loan, in
arrears,  on  the  last  day of each Interest Period, upon any prepayment of the
Loan  (to  the  extent  of  accrued  interest on the principal amount, including
Capitalized  Interest, of the Loan so prepaid) and at maturity of the Loan.  The
"Interest Period" means (i) initially, the period commencing on the Closing Date
 ---------------
and ending on the next succeeding Interest Payment Date (as hereinafter defined)
and  (ii)  thereafter,  each  quarterly  period  ending  on  May  15, August 15,
November15,  or  February  15,  as  applicable  (each  such date for an interest
payment  an  "Interest  Payment  Date");  provided that no Interest Period shall
              -----------------------     -------- ----
extend  beyond  the  Maturity  Date.  Notwithstanding  the  foregoing,  if  the
aggregate  amount  of  accrued  and  unpaid  interest (including all Capitalized
Interest)  and  all  unpaid original issue discount on any Interest Payment Date
occurring  after  the  fifth  anniversary  of the Closing shall exceed an amount
equal to the product of (x) the issue price (as defined in Code Sections 1273(b)
and  1274(a))  of  the  Note  and  (y) the yield to maturity (as defined in Code
Section  163(i))  of  the  Loan  (such product being the "Maximum Accrual"), all
                                                          ---------------
accrued  and  unpaid  interest  on  the Loan in excess of an amount equal to the
Maximum  Accrual shall be paid by the Company to the holders of the Note on such
Interest  Payment  Date.  Any  accrued  interest  which  for  any reason has not
theretofore  been  paid  shall  be  paid  in full on the date on which the final
principal  payment  on  the  Loan  is  made.

     3.2.3.     Interest on the Loan shall be computed on the basis of a 360-day
year  of  twelve  30-day  months.  In  computing  such interest, the date of the
making  of the Loan shall be included and the date of payment shall be excluded.

     3.3     Payment  of  the  Loan.  All  of  the  Loan
             ----------------------

Obligations,  this  Agreement will terminate except as provided in Section 10.6.
                                                                   -------------
Notwithstanding any such termination, until all Loan Obligations have been fully
paid  and  satisfied  (other  than continuing indemnity obligations), the Lender
shall  be  entitled  to  retain  the ability to exercise all rights and remedies
available  to  the  Lender  under the Subordinated Loan Documents and applicable
laws.

     3.4     Voluntary Prepayments.  Subject to the
             ---------------------
terms  and  conditions  of  the  Senior Loan Documents and the other agreements,
instruments  and  documents evidencing or setting forth the terms and conditions
of the Senior Indebtedness, the Loan may be prepaid, at the Company's option, at
any  time  and from time to time, in whole or in part, without penalty, upon not
less  than  five  (5)  Business Days and not more than thirty (30) Business Days

     3.5     Application  of  Prepayments.  All
             ----------------------------
prepayments  shall  include, notwithstanding Section 3.2.2 above, the payment in
                                             -------------

Capitalized  Interest)  of  the  Loan  so  prepaid  and  shall be applied in the
following  manner:  (i)  first,  payment  of  all  accrued interest (ii) second,
payment  of  Capitalized  Interest  and  (iii)  third,  payment  of  principal.

             ------------------------

     3.6.1.     If  fewer  than  all of the Notes are to be prepaid, the Company
shall  select  the Notes to be prepaid based upon an allocation among all of the
Notes at the time outstanding, and paid to the Holder thereof, in proportion, as
nearly  as  practicable,  to  the  respective  unpaid  amount  of  principal and
interest,  with  adjustments,  to  the extent practicable, to compensate for any
prior  payments  not  made  exactly  in  such  proportion.

     3.6.2.     Upon  surrender  of  a Note that is prepaid in part, the Company
shall  promptly  execute  and deliver to the Holder (at the Company's expense) a
new  Note  equal  in  principal  amount  to  the  unpaid  portion  of  the  Note

interest  (except  for  Capitalized  Interest)  and fees hereunder shall be made
without  defense,  set-off  or  counterclaim, in same day funds and delivered to
each  holder  of  the  Note not later than 12:00 noon (Chicago time) on the date
such  payment  is  due  by  wire transfer of immediately available funds to such
account  as  the  Lender or any holder of Notes may from time to time designate;
provided  that funds received by any such holder after 12:00 noon (Chicago time)
  ------  ----
shall be deemed to have been paid by the Company on the next succeeding Business
Day.

     3.7.2.     Whenever  any  payment  to  be  made hereunder or under the Note
shall  be  stated  to  be  due on a day which is not a Business Day, the payment
shall  be  made  on  the next succeeding Business Day and such additional period
shall  be  included  in  the computation of the payment of interest hereunder or
under  the  Note.

              -----------------------------
notice  to  the Lender and the Company, declare the Notes to be due and payable,
whereupon  the  principal  amount  of the Note held by the Lender, together with
accrued  interest  thereon,  shall  automatically  become  immediately  due  and
payable,  without any other notice of any kind, and without presentment, demand,
protest  or  other  requirements  of any kind, all of which are hereby expressly
waived by the Company.  Notwithstanding the foregoing, with respect to any Event
of  Default  occurring  pursuant  to  Section  7.5  or  Section  7.6 hereof, the
                                      ------------------------------
principal  amount  of  the  Note,  together with accrued interest thereon, shall
automatically  become  immediately  due and payable, without any other notice of
any  kind, and without presentment, demand, protest or other requirements of any
kind,  all of which are hereby expressly waived by the Company.  If any Event of
Default  exists, each Holder of the Notes shall also have any other rights which

other  rights  which  such  holder  may  have  pursuant  to  applicable  law.

SECTION  8.     SUBORDINATION

     8.1     Extent  of  Subordination.  All  amounts  including  all principal,
             -------------------------
interest  (including,  without  limitation, interest accruing after any petition
for  bankruptcy,  insolvency, reorganization or receivership) and other payments
payable  by  the Company with respect to the Loan Obligations (the "Subordinated
                                                                    ------------
Debt")  are and shall be subordinate and junior in right of payment to the prior
----
payment  in  full of the Senior Indebtedness to the extent and in the manner set
forth  in  this  Section  8.
                 ----------

     8.2     Payment  Suspension.
             -------------------

     8.2.1.     No direct or indirect payment (including, without limitation, by
purchase  or  redemption)  by  or  on  behalf of the Company of principal of, or
interest on the Subordinated Debt, will be made if, at the time of such payment,
there  exists  any  event  of default with respect to the Senior Indebtedness (a
"Senior  Default"),  whether  at maturity, on account of mandatory redemption or
 ---------------
prepayment,  acceleration  or  otherwise, and such Senior Default shall not have
been  cured or waived or the benefits of this sentence waived in accordance with
the  Senior  Loan  Documents.

     The  failure to make any payment or distribution when due for or on account
of  this  Agreement  by  reason  of  these  subordination provisions will not be
construed  as  preventing  the  occurrence of any Event of Default in respect of
this  Agreement.

     8.2.2.     If  there is a Senior Default which results in the Company not
making  a payment of principal or interest of the Subordinated Debt, the Company
shall  promptly  provide  to  the  Lender written notice of such Senior Default.

     8.3     Liquidation,  Winding  Up, etc.  Upon any distribution of assets
             ------------------------------
of  the  Company  or  upon  any  dissolution,  winding  up,  liquidation  or
reorganization  of  the  Company,  whether  in  bankruptcy,  insolvency,
reorganization  or receivership proceeding or upon an assignment for the benefit
of  creditors  or  any  other  marshaling  of  the assets and liabilities of the
Company  or  otherwise:

     8.3.1.     the  holders  of  all  Senior  Indebtedness shall be entitled to
receive  payment in full, in cash or cash equivalents, of the principal thereof,
the  interest  due thereon (including interest accruing subsequent to the filing
of,  or  which  would  have  accrued  but  for  the  filing  of,  a petition for
bankruptcy,  whether  or  not  such  interest  is  an  allowable  claim  in such
bankruptcy  proceeding) and any premium or other payment obligation with respect
thereto  before the holders of the Subordinated Debt are entitled to receive any
payment  or  any distribution of assets of the Company of any kind or character,
whether  in  cash,  property  or  securities,  by set-off or otherwise, upon the
Subordinated  Debt;  and

     8.3.2.     any payment or distribution of assets of the Company of any kind
or  character, whether in cash, property or securities, by set-off or otherwise,
to  which  the  holders  of  the Subordinated Debt would be entitled but for the
provisions  of  this Section 8 shall be paid by the liquidating trustee or agent
                     ---------
or  other  Person  making  such  payment  or  distribution, whether a trustee in
bankruptcy,  a  receiver  or  liquidating  trustee or otherwise, directly to the
holders  of  Senior  Indebtedness  or  their agents or representatives or to the
trustee  or  trustees under any indenture under which any instruments evidencing
any  of  such Senior Indebtedness may have been issued, ratably according to the
aggregate  amounts  remaining unpaid on account of the principal of, interest on
and any premium or other amounts payable with respect to the Senior Indebtedness
held or represented by each such holder, to the extent necessary to make payment
in  full,  in  cash  or  cash  equivalents, of all Senior Indebtedness remaining
unpaid,  after  giving  effect  to any concurrent payment or distribution to the
holders  of  the  Senior  Indebtedness.

The  consolidation  of  the  Company  with,  or  the merger of the Company into,
another  entity  shall  not  be deemed a dissolution, winding up, liquidation or
reorganization  of  the  Company,  as  the case may be, for the purposes of this
Section  8.3  if  such  other  entity is organized in the United States and such
------------
entity,  as a part of such consolidation or merger, succeeds to the property and
business  of  the Company, and assumes the obligations of the Company (including
the  Senior  Indebtedness  and  the  Subordinated  Debt).

     8.4     Payment  Held  in  Trust.  All  payments  or  distributions  by the
             ------------------------
Company  upon or with respect to the Subordinated Debt which are received by the
holders thereof in violation of or contrary to the provisions of Sections 8.2 or
                                                                 ---------------
8.3  above  shall  be  received  in  trust for the benefit of the holders of the
---
Senior  Indebtedness  and  shall be paid over upon demand to such holders in the
same  form as so received (with all necessary endorsements) to be applied to the
payment  of  the  Senior  Indebtedness.

     8.5     Acceleration and Remedial Actions.  Notwithstanding anything herein
             ---------------------------------
to  the  contrary  (including  any notice delivery requirements), so long as any
Senior Indebtedness is outstanding, no notice of acceleration shall be given or,
if given, shall be effective with respect to this Agreement, and the Lender will
not  ask for, demand, sue for, take or receive from the Company, by setoff or in
any other manner, the whole or any part of any monies which may now or hereafter
be  owing  by  the  Company  to  the  Lender  with  respect  to  any part of the
Subordinated  Debt  prior  to the Maturity Date thereof or participate as one of
the  initial  petitioning  creditors  in  an  involuntary  petition  under  the
Bankruptcy  Code  or similar insolvency statute against the Company with respect
to  any  part  of  the  Subordinated  Debt  prior  to the Maturity Date thereof.

     8.6     Subrogation.  Upon  receipt  by  the  holders  of  the  Senior
             -----------
Indebtedness  of  amounts  sufficient to pay all Senior Indebtedness in full, to
the  extent  any  amounts  which  are  otherwise  payable  with  respect  to the
Subordinated  Debt  but for the provisions of this Section 8 have been paid over
                                                   ---------
to  the holders of the Senior Indebtedness, the holders of the Subordinated Debt
shall  be  subrogated  to  the  rights  of the holders of Senior Indebtedness to
receive payments or distributions of cash, property or securities of the Company
applicable  to  Senior Indebtedness until the Subordinated Debt is paid in full,
and  no such payments or distributions to the holders of the Senior Indebtedness
of  cash,  property  or  securities  otherwise  distributable  to the holders of
Subordinated  Debt  shall, as between the Company, its creditors (other than the
holders  of  Senior  Indebtedness)  and the holders of the Subordinated Debt, be
deemed  to  be payment by the Company to the holders of the Senior Indebtedness.

     8.7     Reinstatement.  The  provisions of this Section 8 shall continue to
             -------------                           ---------
be effective or be reinstated, as the case may be, if at any time any payment of
any of the Senior Indebtedness is rescinded or must otherwise be returned by the
holders of the Senior Indebtedness for any reason whatsoever (including, without
limitation,  the insolvency, bankruptcy or reorganization of the Company) all as
though  such  payment  had  not  been  made.

SECTION 9.     RESTRICTIONS ON TRANSFER; LEGENDS

     9.1     Assignments  of  Notes.
             ----------------------

     9.1.1.     Subject  to  the  terms  and  conditions  of  the  Senior  Loan
Documents,  the  Lender  shall  have  the  right  at  any time, to sell, assign,
transfer  or  negotiate  all or any part of the Loan and the Note to one or more
Persons  (each  a  "Holder")  (provided  that, so long as no Default or Event of
                    ------
Default  has  occurred  and  is  continuing, the Company's consent to such sale,
assignment,  transfer  or  negotiation shall be required, such consent not to be
unreasonably  withheld  or  delayed), and may grant participations in all or any
part  of  the Note or the Loan evidenced thereby to one or more Persons.  In the
case of any sale, assignment, transfer or negotiation of all or part of the Note
authorized  under  this  Section 9.1.1 (but not in the case of a participation),
                         -------------
the  assignee,  transferee  or recipient shall have, to the extent of such sale,
assignment,  transfer  or negotiation, the same rights, benefits and obligations
as  it would if it were a Lender with respect to such Note or the Loan evidenced
thereby.

     9.1.2.     The  Company  shall  keep  at its principal office a register in
which  the  Company  shall  provide for the registration of the Note and for the
transfer  of  the same.  Upon surrender for registration of transfer of any Note
at  the  principal  office  of  the  Company, the Company shall, at its expense,
promptly  execute  and deliver one or more new Notes of like tenor and of a like
principal  amount,  registered  in the name(s) of such transferee(s) and, in the
case  of  a transfer in part, a new Note in the appropriate amount registered in
the  name(s)  of  such  transferor(s).

     9.1.3.     In  connection  with  any sales, assignments or transfers of any
Note,  the  transferor  shall  give  notice to the Company and the Lender of the
identity  of  such  parties  and obtain agreements from the transferees that all
nonpublic  information  given to such parties pursuant to this Agreement will be
held  in  strict  confidence  pursuant to a confidentiality agreement reasonably
satisfactory  to  the  Company.

behalf  of any other subsequent holder of the Note) represents and warrants that
as  of  the  Closing  Date:

     (a)     Restrictions  on  Transfer.  The Lender
             --------------------------
has  been advised that the Note has not been registered under the Securities Act
or  any  state  securities  laws  and,  therefore, cannot be resold unless it is
registered  under  the  Securities  Act  and applicable state securities laws or
unless  an  exemption  from  such  registration  requirements is available.  The
Lender  is  aware  that  the  Company  is under no obligation to effect any such
registration  with  respect  to  the  Note  or  to  file  for or comply with any
exemption  from registration and that the Company does not intend to effect such
registration.  The  Lender  is receiving the Note from the Company hereunder for
its  own  account  and not with a view to, or for resale in connection with, the
distribution thereof in violation of the Securities Act; provided, however, that
                                                         --------  -------
except  as  provided  in  the  this  Agreement,  the disposition of the Lender's
property  shall  at  all  times  be  and  remain  in  its  control.

     (b)     Accredited  Investor,  etc.  The  Lender  and  each Holder has such
             --------------------------
knowledge  and  experience in financial and business matters so as to be capable
of  evaluating  the  merits  and  risks  of  such investment, is able to incur a
complete  loss  of  such  investment  and  to  bear  the  economic  risk of such
investment  for  an  indefinite  period  of  time.  The Lender is an "accredited
investor"  as  that  term  is  defined in Regulation D under the Securities Act.

     9.2.2.     Restrictive  Legend.  Each  Note
                -------------------
shall  bear  a  legend  in  substantially  the  following  form:

"THIS  NOTE  WAS  ISSUED  IN A PRIVATE PLACEMENT, WITHOUT REGISTRATION UNDER THE
SECURITIES  ACT  OF  1933, AS AMENDED (THE "ACT") AND MAY NOT BE SOLD, ASSIGNED,
PLEDGED  OR  OTHERWISE  TRANSFERRED  IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
STATEMENT  UNDER  THE  ACT  COVERING  THE  TRANSFER  OR  AN  OPINION  OF COUNSEL
ACCEPTABLE  TO THE ISSUER THAT SUCH REGISTRATION UNDER THE ACT IS NOT REQUIRED."

     9.3     Termination  of  Restrictions.
             -----------------------------
The  restrictions  imposed by Section 9.2 hereof upon the transferability of the
                              -----------
Note  shall  cease  and  terminate  as  to  the Note (i) when, in the opinion of
counsel,  which  counsel  shall  be  knowledgeable  in securities laws and which
opinion  shall  be  reasonably satisfactory to Company, such restrictions are no
longer  required  in  order to assure compliance with the Securities Act or (ii)
when  such  Note  shall  have  been  registered  under  the  Securities  Act  or
transferred  pursuant  to Rule 144 thereunder.  Whenever such restrictions shall
cease  and  terminate  as to any Notes or such Notes shall be transferable under
paragraph  (k) of Rule 144, the holder thereof shall be entitled to receive from
the  Company, without expense, new certificates not bearing the legend set forth
in  Section  9.2  hereof.
    ------------

     9.4     Note  Legend Relating to Subordination.
             --------------------------------------
Each  Note  shall  bear  a legend in substantially the following form:

"THIS  NOTE  AND  THE RIGHTS AND OBLIGATIONS EVIDENCED HEREBY ARE SUBORDINATE TO
