          Re: Amendment to Loan Documents

Dear Jeanette:

This Letter  Agreement will  serve to  confirm certain  agreements  of
Merrill Lynch  Business  Financial  Services  Inc.  ("MLBFS")  and  TM
Century, Inc. ("Customer'') with respect to: (i) that certain  WORKING
CAPITAL MANAGEMENT ACCOUNT  AGREEMENT AND RELATED  WCMA NOTE NO.  586-
07R66 between MLBFS  and Customer (including  any previous  amendments
and extensions thereof), and (ii)  all other agreements between  MLBFS
and  Customer  in  connection   therewith  (collectively,  the   "Loan
Documents"). Capitalized  terms used  herein  and not  defined  herein
shall have the meaning set forth in the Loan Documents.

Subject to the terms hereof, effective as of the "Effective Date", the
Loan Documents are hereby amended as follows:

1 .Subject to the terms of the Loan Documents (including the Letter of
Credit Supplement  included therein),  MLBFS  has approved  letter  of
credit availability  for  Customer  under the  WCMA  Line  of  Credit,
limited to the lesser of: (i)  $200,000.00 or (ii) the then  remaining
availability under  Customer's WCMA  Line of  Credit. Each  letter  of
credit will be issued by a  corresponding bank after approval both  by
MLBFS and that bank as to the terms of the requested letter of  credit
and execution by Customer of all documents required by MLBFS and  that
bank. Each letter of credit will  be subject to the approval of  MLBFS
and the  issuing  bank, and  when  issued will  reduce  the  remaining
availability under Customer's  WCMA Line of  Credit by  the amount  of
such letter of credit  and its related fees.  In connection with  said
letter of credit availability, Customer acknowledges and agrees:

(a) Concurrently  with its  acceptance hereof,  Customer will  pay  to
MLBFS by check a non-refundable Letter of Credit Commitment Fee in the
amount of $500.00.

(b) All other fees will be charged in accordance with the terms of the
Letter of Credit Supplement included in the Loan Documents.

(c) No letter of credit expiry date shall extend beyond the Maturity
Date.



Additional fees  may  apply  under  certain  circumstances.  All  fees
(except for the Letter  of Credit Commitment Fee)  will be charged  to
Customer's WCMA Account  at the  applicable time.  Please be  advised,
generally a letter of credit takes a minimum of 72 hours to be  issued
from the  date the  required documents  are returned  and accepted  by
MLBFS.

Page No. 2

Except as expressly amended hereby, the Loan Documents shall  continue
in full force and effect upon all of their terms and conditions.

Customer acknowledges, warrants and agrees, as a primary inducement to
MLBFS to enter into this Agreement,  that: (i) no default or Event  of
Default has occurred and is continuing under the Loan Documents;  (ii)
each of the warranties of Customer in the Loan Documents are true  and
correct as of the  date hereof and  shall be deemed  remade as of  the
date hereof; (iii) Customer does not  have any claim against MLBFS  or
any of its affiliates  arising out of or  in connection with the  Loan
Documents or any other matter whatsoever,  and (iv) Customer does  not
have any defense  to payment  of any amounts  owing, or  any right  of
counterclaim for any reason under, the Loan Documents.

The amendments and  agreements in  this Letter  Agreement will  become
effective on the date (the "Effective Date") upon which: (i)  Customer
shall have executed  and returned the  duplicate copy  of this  Letter
Agreement and the other document enclosed herewith; (ii) an officer of
MLBFS shall have reviewed and approved this Letter Agreement and  said
other document as being consistent in  all respects with the  original
internal authorization  hereof; and  (iii) to  the extent  applicable,
MLBFS shall  have  entered  such  amendments  and  agreements  in  its
computer system (which MLBFS agrees to  do promptly after the  receipt
of such executed duplicate  copy and other document).  Notwithstanding
the foregoing. if for  any reason other than  the sole fault of  MLBFS
the Effective Date  shall not occur  within 14 days  from the date  of
this Letter  Agreement, then  all of  said amendments  and  agreements
herein will, at the sole option of MLBFS, be void.

Very truly yours,

                     LETTER OF CREDIT SUPPLEMENT

This LETTER OF CREDIT SUPPLEMENT ("Supplement") is hereby made a  part
of that  certain  WORKING  CAPITAL MANAGEMENT  ACCOUNT  AGREEMENT  AND
RELATED WCMA  NOTE AND  SECURITY AGREEMENT  NO. 586-07R66  (the  "Loan
Agreement") between  MERRILL LYNCH  BUSINESS FINANCIAL  SERVICES  INC.
("MLBFS") and TM CENTURY, INC ("Customer').

In connection  with Customer's  WCMA Line  of  Credit under  the  Loan
Agreement, Customer may  from time to  time apply for  the opening  of
letters of credit  by an  Issuing Bank, subject  in each  case to  the
consent  and  approval  of  MLBFS.  This  Supplement  sets  forth  the
understandings between MLBFS and Customer with respect to any and  all
such letters of credit.

Accordingly, and  in  consideration of  the  mutual covenants  of  the
parties hereinafter  set forth,  MLBFS and  Customer hereby  agree  as
follows:

1. DEFINITIONS.

(a) Specific Terms. In addition to terms defined elsewhere in the Loan
Agreement  or  in  any  exhibit  or  amendment  thereto  or   document
incorporated therein (which terms shall have the same meaning herein),
when used  herein,  the  following  terms  shall  have  the  following
meanings:

(i) "Application" shall mean the applicable Issuing Bank's document or
documents used to apply for and request, with MLBFS' prior approval, a
Credit to be issued by such Issuing Bank under this Supplement and the
applicable CLC Agreement.

(ii) "Business Day" means  any day upon  which the applicable  Issuing
Bank's principal office is open for  the conduct of substantially  all
of its banking functions.

(iii) "CLC Agreement" means that agreement which Customer enters  into
with the  applicable Issuing  Bank in  consideration of  such  Issuing
Bank's role in connection with the Letter of Credit Arrangement  under
the WCMA Program.

(iv) "Credit" means a letter of credit authorized and agreed to by the
applicable Issuing Bank from  time to time to  be issued on  Customers
behalf and which is issued by such Issuing Bank at Customer's  request
with MLBFS'  consent  while this  Supplement  and the  applicable  CLC
Agreement are in effect.

(v) "Document" means not only documents  of title, but also all  other
papers,  securities,   invoices,   certificates,   letters,   notices,
receipts, telegrams,  telex or  telephonic transmissions,  facsimiles,
computer data printouts and any other tangible expression of words  or
data, whether transmitted or delivered by written, electromagnetic  or
other means.


(vi) "Draft" means any bill of exchange or acceptance, whether payable
at sight or at a future time. If a Credit provides for presentation of
      
Documents without Drafts,  references herein  to Drafts,  acceptances,
Documents relative thereto or  payments or acceptances thereof,  shall
refer to Documents  presented for  payment against  or acceptances  of
such Documents, and all rights and obligations hereunder shall be  the
same as though Drafts had accompanied such Documents.

(vii) "Issuing  Bank" refers  as of  the date  hereof to  Mellon  Bank
(East) National Association ("Mellon")  or The Northern Trust  Company
("Northern")  or  Bank   of  America  Illinois   (formerly  known   as
Continental Bank,  N.A.)  ("Bank  of  America'3,  as  applicable,  and
"Issuing Banks" refers as of the  date hereof to Mellon, Northern  and
Bank of America, collectively. MLBFS reserves the right without notice
to or the consent of Customer to
      
designate any other or additional financial institutions as an Issuing
Bank, and upon any such designation by MLBFS, such other or additional
financial institutions shall be included in the definition of  issuing
Bank and Issuing Banks for all purposes hereof.

(viii) "Letter of Credit Arrangement" shall mean the arrangement  made
between MLBFS and each  Issuing Bank with respect  to the issuance  of
Credits in connection with the WCMA Program.

(b) Other Terms. Except as otherwise provided herein or in the Loan
Agreement, other terms herein shall
have the meaning assigned to them by the "Uniform Customs and Practice
for Documentary Credits"
(1983 Revision) International Chamber of Commerce Publication No. 500.

2.   APPLICATIONS FOR THE ISSUANCE OF CREDITS.

Each Application executed by Customer shall constitute a certification
by Customer that all representations  and warranties made by  Customer
in this  Supplement, the  applicable CLC  Agreement  and in  the  Loan
Agreement are true  and correct as  of the date  of such  Application.
Upon receipt of  an Application,  MLBFS may  elect, but  shall not  be
required, to request that an Issuing  Bank issue or amend a Credit  in
connection with  MLBFS'  Letter  of  Credit  Arrangement  in  response
thereto.  In  no  event,  however,  shall  (i)  the  aggregate  amount
outstanding under all  such Credits  exceed $200,000.00,  or (ii)  the
expiration date of any Credit extend  beyond the Maturity Date of  the
WCMA Line of  Credit. Amendments to  any Application  and requests  to
amend any Credit issued shall be in accordance with the procedures  of
the applicable  Issuing  Bank  and MLBFS  governing  such  amendments.
Customer expressly  acknowledges  and agrees  that  in order  to  make
Applications or request amendments by  certain means permitted by  the
procedures of the  applicable Issuing Bank  and MLBFS (including,  but
not limited to, microcomputer transmissions), Customer may be required
to execute one or more additional agreements governing the rights  and
duties of  Customer,  the  Issuing  Bank  and/or  MLBFS  with  respect
thereto. Customer  further  acknowledges  and  agrees  that  upon  the
issuance of  each Credit,  the  WCMA Line  of  Credit under  the  Loan
Agreement will be reduced by the amount of such Credit so long as such
Credit remains outstanding.


3. PAYMENT OBLIGATIONS.

(a) Customer unconditionally  agrees to pay  to MLBFS: (i)  as to  any
Drafts or claims drawn  under or made in  connection with any  Credit,
all amounts  paid  or  payable  by MLBFS  under,  pursuant  to  or  in
connection with such  Credit; (ii) all  fees and charges  of MLBFS  in
connection with such Credit and/or Application, which fees and charges
shall be in such amount  or at such rate  as MLBFS shall determine  in
its sole discretion; and  (iii) any and  all expenses, obligations  or
charges paid or incurred by MLBFS, the applicable Issuing Bank or  any
of its correspondents in connection with such Credit, this  Supplement
and/or the applicable CLC Agreement. A  schedule of the current  fees,
charges and limitations applicable to  this Supplement and any  Credit
issued pursuant hereto is set forth  on Exhibit A attached hereto  and
hereby made a  part hereof.  The Commitment  Fee referred  to on  said
Exhibit A shall apply only with respect to the period between the date
hereof and the current  Maturity Date of the  WCMA Line of Credit.  In
the event of  any renewal of  the WCMA Line  of Credit, an  additional
Commitment Fee  shall be  payable in  the  amount then  determined  by
MLBFS. The acceptance of any Commitment Fee by MLBFS shall not in  any
event obligate  MLBFS to  consent to  the issuance  of any  Credit  or
particular number of Credits. No fees  or charges shall be  refundable
under any circumstances.

(b) Provided that no Event of Default shall then have occurred and  is
continuing, within a  reasonable time  after the  presentation of  any
Drafts or  other third  party claims  in connection  with any  Credit,
MLBFS will increase the WCMA Line of Credit by an amount equal to  the
lesser of: (i) the aggregate amount of such Drafts or claims, or  (ii)
the amount by which the WCMA Line of Credit was previously reduced  on
account of such Credit.

(c) Without limiting in  any way Customer's  obligations to pay  MLBFS
any amounts due  pursuant to or  in connection with  any Credit,  this
Supplement  or   the  applicable   CLC  Agreement,   Customer   hereby
irrevocably authorizes MLBFS to  pay on Customers  behalf any and  all
amounts due  pursuant to  or in  connection with  any Credit  or  this
Supplement or the  applicable CLC Agreement,  upon the  demand of  the
applicable Issuing Bank for payment.

(d) In order to make such  payments to the applicable Issuing Bank  on
Customers behalf, or   MLBFS for  the fees and  charges referred  to
above or other  sums payable, Customer  hereby irrevocably  authorizes
MLBFS to: (i) debit Customers WCMA Account, electronically, by  draft,
and/or by any other means that  MLBFS may in its sole discretion  deem
appropriate, and Customer understands and agrees that such debit  may,
without limitation, cause the redemption of any and all of  Customer's
shares in a CMA money market fund and/or the withdrawal of any and all
of its  deposits  maintained  in  any  ISA  arrangement  and  Customer
irrevocably  authorizes  Merrill   Lynch,  Pierce,   Fenner  &   Smith
Incorporated  to  redeem  and/or  withdraw  such  fund  shares  and/or
deposits to pay the amounts to MLBFS; and (ii} should an  insufficient
amount of or no cash, CMA money market fund shares and/or ISA balances
be available in Customers WCMA  Account, advance funds from  Customers
WCMA Line of Credit on account  thereof; all without notice to or  any
separate consent of Customer.


(e) All payments to which MLBFS is entitled shall be made to MLBFS  by
Customer free and clear of and  without deduction for any present  and
future foreign  taxes, exchange  regulation charges  or other  levies,
deductions or withholdings of  any kind, and shall  be made in  United
States currency.

4. EXAMINATION OF CREDITS, INSTRUMENTS AND DOCUMENTS: DISCREPANCIES.

(a) Customer shall  promptly examine a  copy of each  Credit (and  any
amendments thereto) sent to it by MLBFS and/or an Issuing Bank and all
other instruments and  documents (or copies  thereof) delivered to  it
from time to  time by  MLBFS and/or  such Issuing  Bank in  connection
therewith, and Customer shall, within one Business Day of its  receipt
thereof, notify MLBFS  and such Issuing  Bank by telecommunication  or
other  expeditious  means   of  communication   of  any   discrepancy,
irregularity or  claim of  non-compliance  with the  instructions  set
forth in the  appropriate Application or  amendment request.  Customer
shall be conclusively deemed  to have waived  any claim against  MLBFS
and such Issuing Bank and its  correspondents in connection with  such
Credit unless it notifies  MLBFS and such  Issuing Bank in  accordance
with the term of the previous sentence.

(b) In  the  event  that MLBFS  and/or  the  applicable  Issuing  Bank
notifies Customer  as to  any discrepancy  between any  instrument  or
document presented  under  any Credit  and  the requirements  of  such
Credit, Customer shall, within one Business Day of its receipt of such
notice (:or such shorter interval as circumstances may require and  of
which the applicable Issuing Bank shall advise Customer), notify MLBFS
by telecommunication or other expeditious means of communication as to
Customers acceptance or  non-acceptance thereof.  Customer shall  also
notify such  Issuing Bank  of all  such instances  in accordance  with
terms of the applicable CLC Agreement. Customer shall be  conclusively
deemed to waive any claim of improper honor or dishonor of any Credit,
or of improper payment  therefor, if it fails  to so notify MLBFS  and
such Issuing Bank within the time and in the manner required herein.

5. COMPLIANCE WITH LEGAL REQUIREMENTS.

Customer shall procure  all licenses and  comply with all  formalities
necessary for  the import,  export and  shipping  of any  property  in
connection with  any  Credit  and shall  comply  with  all  applicable
domestic and  foreign laws,  orders and  regulations (including  those
relating to exchange).  Upon MLBFS' request,  Customer shall  promptly
furnish MLBFS and the Issuing  Bank with certificates evidencing  such
compliance. Customer  hereby  certifies and  warrants  to MLBFS  on  a
continuing basis  that:  (i)  no  transactions  with  respect  to  any
property shipped  in  connection  with  any  Credit  are  or  will  be
prohibited  under  any  United  States   or  foreign  law,  order   or
regulation, and (ii) each shipment covered by any Credit or regulation
and any  Documents required  thereunder, shall  fully conform  to  all
applicable United States and foreign laws, orders and regulations.



6. LIMITATIONS.

(a) Customer agrees that neither  MLBFS, the applicable Issuing  Bank,
nor any of its correspondents shall be responsible for, and  Customers
obligation to pay and/or reimburse MLBFS shall not be affected by: (i)
acts or omissions of any other person, including, without  limitation,
any beneficiary  or assignee  of any  Credit, and  any  correspondent,
agent or sub-agent;  (ii) the existence,  character, nature,  quality,
quantity, condition, packing value or delivery of goods purporting  to
be  represented  by  Documents;   (iii)  the  validity,   sufficiency,
genuiness or  collectibility  of Documents  (including  insurance)  or
instruments, or of any endorsements thereon; (iv) any irregularity  in
connection with shipment, including,  without limitation, any  default
or fraud by the shipper or others, the time, place, manner or order of
shipment, non-shipment of  goods or partial  or incomplete  shipments,
failure to  arrive or  delay  in arrival  of  goods or  Documents,  or
failure to give notice of shipment  or arrival of goods or  Documents;
(v) breach of contract between Customer and any Credit beneficiary  or
other party;  (vi)  consequences  of  compliance  with  laws,  orders,
regulations or customs in effect in  places of negotiation or  payment
of any Credit;  (vii) failure of  Drafts or other  payment demands  to
bear reference or adequate reference to any Credit; (viii) failure  of
any negotiating bank to comply with MLBFS' directions, (ix) failure of
any party to surrender or take up any Credit, (x) failure of any party
to note the amount of any Draft or payment demand on the reverse  side
of any Credit, or forward Documents  apart from Drafts as required  by
the terms of any Credit (each  of which requirements may be waived  by
the applicable  Issuing Bank  even if  included in  any Credit);  (xi)
errors, omissions, interruptions or delays in transmission or delivery
of any messages, however sent and whether plain or in code or  cipher,
or errors  in  translation or  interpretation  of technical  or  other
terms; or  (xii) without  limiting the  foregoing,  any other  act  or
omission not done or omitted in bad faith.

(b) MLBFS shall have no duty to inquire into: (i) the existence of any
disputes or controversies between Customer and the beneficiary of  any
Credit  or  any  other  person,  'including  without  limitation   the
applicable Issuing Bank and/or its correspondents, or (ii) the  truth,
accuracy or  occurrence  of any  fact  or  event referred  to  in  any
certificate or other  Document presented under  or in connection  with
any Credit.  MLBFS'  sole  obligation shall  be  limited  to  honoring
requests for payment by the applicable Issuing Bank made under and  in
compliance with any Credit  notwithstanding: (A) any assistance  which
MLBFS may  have rendered  in connection  with the  preparation of  the
wording of the Credit or any  certificate or other Documents  required
to be presented thereunder,  or (B) any  awareness or knowledge  which
MLBFS may have concerning any transaction giving rise to any Credit.




7. INDEMNIFICATION AND INCREASED COSTS.

(a) Customer  agrees  to  indemnify and  hold  MLBFS,  the  applicable
Issuing Bank  and its  correspondents and  their respective  officers,
agents, directors, successors  and assigns harmless  from and  against
any and  all  claims,  losses,  liabilities  and  expenses  (including
reasonable attorneys' fees) resulting  from or incurred in  connection
with this Supplement, any Application and/or any Credit, and,  without
limiting the foregoing, Customer agrees to bear and pay all reasonable
expenses of every kind for the enforcement of any of MLBFS' and/or the
applicable Issuing Bank's rights herein mentioned  or of any claim  or
demand by MLBFS and/or the  applicable Issuing Bank against  Customer;
excluding, however, from said indemnity any such claims,  liabilities,
etc. arising directly out of the willful wrongful act or active  gross
negligence of MLBFS or  the Issuing Bank. If  any attorney is used  at
any time or from time  to time to enforce  any of said obligations  or
this Supplement or to represent MLBFS and/or such Issuing Bank in  any
legal proceeding concerning any Credit (including, without limitation,
any attempt by  Customer to  enjoin or  delay MLBFS'  payment for  the
honor of a draft or payment demand under any Credit), MLBFS' and  such
Issuing Bank's reasonable attorneys' fees shaft be added thereto.

(b) If any law or regulation, any change in any law or regulation,  or
any  interpretation  thereof  by   any  court  or  administrative   or
governmental authority  charged or  claiming to  be charged  with  the
administration thereof, or any change in generally accepted accounting
principles applicable  to MLBFS  and/or the  applicable Issuing  Bank,
shall: (i)  impose, modify  or make  applicable any  reserve,  special
deposit or  similar requirement  against any  Credits issued  by  such
Issuing Bank or with respect to this Supplement or the applicable  CLC
Agreement, the  Credit or  any related  Document or  any  transactions
hereunder or thereunder, or {ii) impose on MLBFS and/or the applicable
Issuing Bank any other condition regarding this
Supplement, the applicable  CLC Agreement, the  Credit or any  related
Document, or (iii) subject MLBFS and/or the applicable Issuing Bank to
any tax, charge, fee, deduction or withholding of any kind  whatsoever
and the result of any such event  or any similar measure, shall be  to
increase the cost  to MLBFS or  to such Issuing  Bank with respect  to
issuing or maintaining any Credit or to reduce the amount of principal
of, interest on, or any fee or compensation receivable by MLBFS and/or
such Issuing  Bank  in  respect of  any  Credit  or  this  Supplement,
Customer shall  promptly  pay to  MLBFS  or such  Issuing  Bank,  upon
demand, and from  time to  time upon  receipt from  MLBFS and/or  such
Issuing Bank of a certificate as to such increased cost, completed  as
of the effective date of such change of interpretation, all additional
amounts which are  necessary to compensate  MLBFS and/or such  Issuing
Bank for  such  increased  cost.  A  certificate  from  MLBFS  or  the
applicable Issuing Bank as to increased costs shall show the manner of
calculation and shall be conclusive (absent manifest error) as to  the
amount thereof, In  addition, without limiting  the foregoing, if  any
such change  in  applicable  law  or  regulations,  or  interpretation
thereof or in generally  accepted accounting principles should  occur,
but such change or interpretation does not increase any cost or reduce
any fee or compensation, Customer nevertheless agrees to pay to  MLBFS
a fee  which  will adequately  compensate  MLBFS, in  its'  reasonable
judgment, for any adverse non-monetary impact on MLBFS.




8. INSURANCE.

Customer shall keep all property shipped in connection with any Credit
insured in such amounts, against such risks, upon such terms and  with
such insurers as may be required by MLBFS from time to time, and shall
furnish  to  MLBFS  on  request   a  certificate  or  other   evidence
satisfactory to  MLBFS of  such  insurance. Customer  understands  and
agrees that any  insurance required to  be obtained  pursuant to  this
Section is and  shall be  deemed supplemental  to any  required by  or
obtained in favor of the applicable Issuing Bank.

9. RESERVATION OF  RIGHTS OF MLBFS.  MLBFS RESERVES THE  RIGHT AT  ANY
TIME WITHOUT NOTICE TO OR THE CONSENT OF CUSTOMER TO: (i) TERMINATE OR
MODIFY IN ANY MANNER ITS LETTER OF CREDIT ARRANGEMENT WITH ANY ISSUING
BANK, (ii) TERMINATE ITS LETTER OF  CREDIT PROGRAM, (iii) REFUSE  WITH
OR WITHOUT CAUSE TO  APPROVE ANY REQUEST OR  REQUESTS OF CUSTOMER  FOR
ISSUANCE OR AMENDMENT  OF A CREDIT  AND (iv) TERMINATE  OR AMEND  THIS
SUPPLEMENT AND CUSTOMER'S RIGHTS HEREUNDER.

10. MISCELLANEOUS.

(a) Customer shall furnish MLBFS with a list of persons authorized  to
act for Customer in connection  with this Supplement, any  Application
or any  Credit issued  pursuant to  this  Supplement. MLBFS  shall  be
authorized and entitled to rely  upon any written or  tele-transmitted
Application or other communication or  any message or conversation  by
telephone received  or purporting  to be  received  from one  of  such
persons or any other  person reasonably believed by  MLBFS to be  duly
authorized to act for Customer hereunder.

(b) Customer shall  not assign any  of its  rights and/or  obligations
hereunder unless the prior  written consent of each  of MLBFS and  the
applicable Issuing Bank is obtained. Customer acknowledges and  agrees
that MLBFS may freely assign or delegate any of its rights and  duties
hereunder, or in  connection with any  Credit, to  any entity  without
notice to or the consent of Customer.

(c) No delay on the part of MLBFS and/or the applicable Issuing  Bank,
or on  the part  of any  assignee, in  exercising any  power or  right
hereunder shall operate as a waiver  of any power or right; nor  shall
any single  or  partial  exercise of  any  power  or  right  hereunder
preclude other or  further exercise thereof,  or the  exercise of  any
other power  or  right.  The  rights  and  remedies  herein  expressly
specified are  cumulative and  not exclusive  of any  other rights  or
remedies which  MLBFS and/or  the applicable  Issuing Bank  or any  of
their assigns may otherwise have or would have under applicable law.

(d) This  Supplement  shall  be interpreted,  construed  and  enforced
according to the laws of the State of Illinois, and may be enforced in
any jurisdiction in which the Loan Agreement may be enforced.

(e) MLBFS  is hereby  irrevocably authorized,  but not  obligated,  to
obtain and receive any and all  communications and/or material of  any
nature whatsoever relating to Credits or in connection with
Customer's participation  in  MLBFS'  Letter  of  Credit  Arrangement,
including, without limitation, any and  all communications from or  to
the applicable Issuing Bank.


(f)  All  notices  and  other  communications  required  or  permitted
hereunder shall be given and shall become effective in the manner  and
at the time set forth in the Loan Agreement.

(g) If Customer shall fail to do any act or thing it has covenanted to
do under this  Supplement or the  applicable CLC Agreement  or if  any
representation or warranty on the part  of Customer contained in  this
Supplement or the CLC Agreement shall  be breached, MLBFS may, in  its
sole discretion, after 5 days written  notice is sent to Customer,  do
the same or cause  it to be done  or remedy any  such breach, and  may
expend its funds for such purpose; and any and all amounts so expended
by MLBFS  shall be  repayable to  MLBFS by  Customer immediately  upon
MLBFS' demand therefor, with interest  at the Interest Rate  described
in the Loan Agreement  during the period from  and including the  date
funds are so expended by MLBFS to the date of repayment, and any  such
amounts due  and  owing  MLBFS  shall  be  additional  Obligations  of
Customer to MLBFS secured hereunder and under the Loan Agreement.

(h) Customer agrees to do such further acts and things and to  execute
and deliver  to  MLBFS  such additional  agreements,  instruments  and
documents as MLBFS may reasonably require  or deem advisable to  carry
into effect the purposes of this Supplement, or to confirm unto  MLBFS
its rights, powers and remedies under this Supplement.

(i) This Supplement  shall be governed  by and  interpreted under  the
laws of the State  of Illinois, and  may be enforced  by MLBFS in  any
jurisdiction where the Loan Agreement may be enforced.

(j) Whenever  possible, each  provision of  this Supplement  shall  be
interpreted is  such  manner  as  to  be  effective  and  valid  under
applicable law. Any provision of  this Supplement which is  prohibited
or unenforceable in any jurisdiction  shall, as to such  jurisdiction,
