shall be  evidenced  by a  revolving  line of  credit  note  (which  note may be
modified,  renewed  and/or  extended),  substantially  in the form of  Exhibit A
attached  hereto,  or other  instruments  issued or made by  Borrower  to CDWCC.
Except as  otherwise  provided in this  Agreement  or in any notes  executed and
delivered by Borrower to CDWCC in connection herewith,  the principal portion of
Borrower's  Liabilities  shall be payable by Borrower  to CDWCC on the  maturity
date(s)  described  in any such  note(s) (as the same may be amended or renewed)
and  all  costs,  fees  and  expenses  payable  hereunder  or  under  the  Other
Agreements,  shall be payable by Borrower to CDWCC on demand,  in either case at
CDWCC's  principal  place of business or such other place as CDWCC shall specify
in writing to Borrower.

         2.2 Single Obligation.  All of Borrower's  Liabilities shall constitute
one loan secured by CDWCC's security interest in the Collateral and by all other
security interests,  liens, claims and encumbrances heretofore,  now and/or from
time to time hereafter granted by Borrower to CDWCC.

         2.3 Continuing Warranty and  Representation.  The Loan made by CDWCC to
Borrower  pursuant to this Agreement or the Other Agreements shall constitute an
automatic  warranty and  representation by Borrower to CDWCC that there does not
then  exist an "Event  of  Default"  (as  hereinafter  defined)  or any event or
condition which with notice,  lapse of time and/or the making of such loan would
constitute an Event of Default.



 4


         2.4 Term of Agreement.  This Agreement  shall be in effect until all of
Borrower's  Liabilities  have been paid in full and any and all  commitments  of
CDWCC to make loans have terminated.

         2.5 Borrowing Base Certificate.  Provided that an Event of Default does
not then  exist or would not then be  created  thereby  or any event  which with
notice or lapse of time or both would  constitute  an Event of Default  does not
then exist, CDWCC, for such period of time as this Agreement shall be in effect,
shall loan to  Borrower an amount (the  "Borrowing  Base")  equal to one hundred
three  percent  (103%) of the Book Value (which  includes  equipment,  taxes and
shipping) of all  Eligible  Leases that are  scheduled on the initial  Borrowing
Base  Certificate,  in the form attached hereto as Exhibit B, delivered to CDWCC
at Closing,  and subsequent  Borrowing Base  Certificates,  in the form attached
hereto as Exhibit B, to be  delivered  by Borrower to CDWCC by the tenth  (10th)
day of each  month  thereafter.  If the Book  Value of the  Eligible  Leases  as
indicated on the Borrowing  Base  Certificate  must be one hundred three percent
(103%) of the loan  outstanding or the difference  between the loan  outstanding
and one hundred  three percent  (103%) of the Book Value of the Eligible  Leases
shall be required to be repaid to CDWCC. Upon CDWCC's request therefor, Borrower
shall attach to each Borrowing Base  Certificate a true and correct copy of such
leases and other documents  relating to the Eligible Leases  scheduled  thereon.
Borrower's  failure to maintain the  collateral  advance rates set forth in this
Paragraph 5 shall be deemed to be an Event of Default hereunder.

         2.6 Loan Advance Requests.  On a periodic basis,  Borrower shall submit
funding  requests  (the "Loan  Advance  Request")  to CDWCC.  Each Loan  Advance
Request  shall consist of new Eligible  Leases  entered into by the Borrower and
various lessees during the most recent previous periods.  CDWCC shall advance to
Borrower the amount  requested in each Loan Advance Request subject to the total
loan limit set forth in the  Borrowing  Base as set forth in Section 2.5 herein.
CDWCC  shall  advance  such funds under each Loan  Advance  Request in an amount
equal to one hundred  three  percent  (103%) of the Book Value  (which  includes
equipment,  taxes and shipping) of all Eligible Leases that are scheduled on the
Loan  Advance  Request,  in the form  attached  hereto  attached  as  Exhibit C,
delivered to CDWCC at the time of each periodic Loan Advance  Request.  All Loan
Advance  Requests are subject to the  Borrowing  Base  limitations  set forth in
Section 2.5 herein.

         2.7 Termination  of Lending  Obligations.  CDWCC's  commitment to  loan
funds  hereunder  shall  expire on the  earlier  of (i) the date on which  CDWCC
demands repayment of Borrower's Liabilities under the terms of any note given by
Borrower to CDWCC,  or (ii) the  occurrence  of an Event of Default  pursuant to
Section 6 hereof.

real and/or personal  property to secure the payment of Borrower's  Liabilities;
or

         (j) the occurrence of a default or an Event of Default under any of the

         6.2 All of CDWCC's  rights  and remedies under  this Agreement and  the
Other Agreements are cumulative and nonexclusive.

         6.3 Upon an Event of Default or the occurrence of any one of the events
described in  Paragraph  6.1,  without  notice by CDWCC to or demand by CDWCC of
Borrower, CDWCC shall have no further obligation to and may then forthwith cease
advancing  monies or  extending  credit to or for the benefit of Borrower  under
this  Agreement  and the Other  Agreements.  Upon an Event of  Default,  without
notice by CDWCC to or demand by CDWCC of Borrower,  Borrower's Liabilities shall
be due and payable, forthwith.

         6.4 Upon  an  Event  of   Default,  CDWCC,  in its  sole  and  absolute

observe or discharge any of its obligations or liabilities  under this Agreement
or the Other Agreements, no remedy of law will provide adequate relief to CDWCC,
and agrees that CDWCC shall be entitled to temporary  and  permanent  injunctive
relief in any such case without the necessity of proving actual damages.

disposition of the Collateral or any other intended  action by CDWCC,  deposited
in the United States mail, postage prepaid and duly addressed to Borrower at the
address specified at the beginning of this Agreement not less than five (5) days
prior to such proposed action, shall constitute commercially reasonable and fair

time to time by an announcement at the time and place of sale or by announcement
at the time  and  place of such  postponed  or  adjourned  sale,  without  being
required  to give a new  notice  of sale.  Borrower  agrees  that  CDWCC  has no
obligation to preserve rights against prior parties to the Collateral.

8.       GENERAL

         8.1 Borrower  waives the right to direct the application of any and all
payments  at any time or  times  hereafter  received  by  CDWCC  on  account  of
Borrower's  Liabilities and Borrower agrees that CDWCC shall have the continuing
exclusive right to apply and reapply any and all such payments in such manner as
CDWCC may deem  advisable,  notwithstanding  any entry by CDWCC  upon any of its
books and records.

         8.2 Borrower  covenants,  warrants  and  represents  to CDWCC that  all
representations  and warranties of Borrower  contained in this Agreement and the
Other  Agreements  shall be true from the time of  Borrower's  execution of this
Agreement to the end of the original  term and each renewal term hereof.  All of
Borrower's warranties, representations, undertakings, and covenants contained in
this  Agreement  or the  Other  Agreements  shall  survive  until  such  time as
Borrower's Liabilities to CDWCC have been paid in full.

         8.3 The terms and provisions of this Agreement and the Other Agreements
shall supersede any prior agreement or understanding of the parties hereto,  and
contain the entire  agreement of the parties  hereto with respect to the matters
covered  hereby.  This  Agreement and the Other  Agreements may not be modified,
altered or amended  except by an  agreement  in writing  signed by Borrower  and
CDWCC.  Except for the  provisions of Section 2 hereof which shall  terminate as
provided in  paragraph  2.6,  this  Agreement  shall  continue in full force and
effect so long as any portion or component of  Borrower's  Liabilities  shall be
outstanding.  Should a claim  ("Recovery  Claim") be made upon CDWCC at any time
for  recovery  of  any  amount  received  by  CDWCC  in  payment  of  Borrower's
Liabilities (whether received from Borrower or otherwise) and should CDWCC repay
all or part of said amount by reason of (1) any judgment, decree or order of any
court  or  administrative  body  having  jurisdiction  over  CDWCC or any of its
property;  or (2) any  settlement  or  compromise  of any  such  Recovery  Claim
effected by CDWCC with the claimant (including Borrower), this Agreement and the
security interests granted CDWCC hereunder shall continue in effect with respect
to the  amount  so  repaid  to the  same  extent  as if such  amount  had  never
originally been received by CDWCC, notwithstanding any prior termination of this
Agreement,  the return of this Agreement to Borrower, or the cancellation of any
notice or other instrument evidencing Borrower's  Liabilities.  Borrower may not
sell, assign or transfer this Agreement,  or the Other Agreements or any portion
thereof.


 16


         8.4 CDWCC's  failure to require  strict  performance by Borrower of any
provision  of this  Agreement  shall not waive,  affect or diminish any right of
CDWCC  thereafter to demand strict  compliance and  performance  therewith.  Any
suspension  or waiver by CDWCC of an Event of  Default  by  Borrower  under this
Agreement or the Other Agreements  shall not suspend,  waive or affect any other
Event of  Default by  Borrower  under this  Agreement  or the Other  Agreements,
whether the same is prior or subsequent  thereto and whether of the same or of a
different type. None of the undertakings,  agreements, warranties, covenants and
representations  of Borrower contained in this Agreement or the Other Agreements
and no Event of Default by Borrower under this Agreement or the Other Agreements
shall be deemed to have been suspended or waived by CDWCC unless such suspension
or waiver is by an  instrument  in  writing  signed by an  officer  of CDWCC and
directed to Borrower specifying such suspension or waiver.

         8.5 If any provision of this  Agreement or the Other  Agreements or the
application   thereof  to  any  Person  or   circumstance  is  held  invalid  or
unenforceable,  the remainder of this Agreement and the Other Agreements and the
application  of such  provision to other  Persons or  circumstances  will not be
affected  thereby and the provisions of this Agreement and the Other  Agreements
shall be severable in any such instance.

         8.6 This Agreement and the Other  Agreements  shall be binding upon and
inure to the benefit of the successors  and assigns of Borrower and CDWCC.  This
provision, however, shall not be deemed to modify Paragraph 8.3 hereof.

         8.7 To the fullest extent  permitted by law,  Borrower hereby agrees to
protect, indemnify, defend and save harmless, CDWCC and its directors, officers,
agents and employees from and against any and all  liability,  expense or damage
of any kind or nature and from any suits,  claims,  or demands,  including legal
fees and  expenses on account of any matter or thing or action or failure to act
by CDWCC, whether in suit or not, arising out of this Agreement or in connection
herewith unless such suit, claim or damage is caused solely by any act, omission
or willful malfeasance of CDWCC, its directors,  officers, agents and authorized
employees.  This  indemnity  is not  intended  to excuse  CDWCC from  performing
hereunder.  This obligation on the part of Borrower shall survive the closing of
the  Loans,  the  repayment  thereof  and any  cancellation  of this  Agreement.
Borrower  shall pay,  and hold CDWCC  harmless  from,  any and all claims of any
brokers,  finders  or agents  claiming  a right to any fees in  connection  with
arranging the financing contemplated hereby.

         8.8 Borrower   hereby   appoints   CDWCC   as   Borrower's   agent  and
attorney-in-fact  for  the  purpose  of  carrying  out  the  provisions  of this
Agreement  and taking any action and  executing  any  agreement,  instrument  or
document  which CDWCC may deem necessary or advisable to accomplish the purposes
hereof which appointment is irrevocable and coupled with an interest. All monies
paid for the purposes herein,  and all costs, fees and expenses paid or incurred
in connection  therewith,  shall be part of Borrower's  Liabilities,  payable by
Borrower to CDWCC on demand.



 17


         8.9 This Agreement, or a carbon,  photographic or other reproduction of
this Agreement or of any Uniform  Commercial Code financing  statement  covering
the  Collateral  or any  portion  thereof,  shall  be  sufficient  as a  Uniform
Commercial Code financing statement and may be filed as such.

         8.10 Except as  otherwise  provided   in the Other  Agreements,  if any
provision  contained in this Agreement is in conflict with, or inconsistent with
any provision in the Other Agreements, the provision contained in this Agreement
shall govern and control.

         8.11 Except as  otherwise  specifically  provided  in this   Agreement,
Borrower waives any and all notice or demand which Borrower might be entitled to
receive  by virtue of any  applicable  statute of law,  and waives  presentment,
demand  and  protest  and notice of  presentment,  protest,  default,  dishonor,
nonpayment,  maturity, release, compromise,  settlement, extension or renewal of
any and all  agreements,  instruments  or documents at any time held by CDWCC on
which Borrower may in any way be liable.

         8.12 Until CDWCC is notified by Borrower to the  contrary in writing by
registered or certified  mail directed to CDWCC's  principal  place of business,
the  signature  upon this  Agreement or upon any of the Other  Agreements of any
partner,  manager,  employee or agent of the  Borrower,  or of any other  Person
designated in writing to CDWCC by and of the foregoing,  shall bind Borrower and
be deemed to be the duly authorized act of Borrower.

         8.13 This  Agreement and  the Other  Agreements  shall be  governed and
controlled by the laws of the State of Illinois.

         8.14 If at any  time  or  times  hereafter  whether  or not  Borrower's
Liabilities are outstanding at such time,  CDWCC: (a) employs counsel for advice
or other representation (i) with respect to the Collateral,  this Agreement, the
Other  Agreements  or the  administration  of  Borrower's  Liabilities,  (ii) to
represent  CDWCC  in any  litigation,  arbitration,  contest,  dispute,  suit or
proceeding or to commence, defend or intervene or to take any other action in or
with  respect  to  any  litigation,   arbitration,  contest,  dispute,  suit  or
proceeding  (whether  instituted by CDWCC,  Borrower or any other Person) in any
way or respect relating to the Collateral, this Agreement, the Other Agreements,
or Borrower's  affairs, or (iii) to enforce any rights of CDWCC against Borrower
or any other Person which may be obligated to CDWCC by virtue of this  Agreement
or the Other Agreements,  including,  without limitation, any Obligor; (b) takes
any action  with  respect to  administration  of  Borrower's  Liabilities  or to

Agreement or the Other Agreements,  including without limitation, CDWCC's rights

to the foregoing,  shall be part of Borrower's Liabilities,  payable by Borrower
to CDWCC on demand.

                              Revolving Credit Note

$10,000,000.00                                            Vernon Hills, Illinois
                                                          ________________, 1999
                                                                       
         For value  received,  the  undersigned,  CDW LEASING,  LLC, an Illinois
limited liability company (the "Borrower"),  promises to pay to the order of CDW
CAPITAL CORP., an Illinois corporation ("CDWCC"), at its principal office at 200
North Milwaukee Avenue,  Vernon Hills,  Illinois 60061, the principal sum of Ten
Million and No/100  Dollars  ($10,000,000.00),  or such lesser  amount as may be
advanced to the  Borrower,  on the day following  receipt of written  demand for
such payment (the "Demand  Date") from the holder  hereof in lawful money of the
United States of America.

         The Borrower promises to pay interest  (computed on the basis of a year
of three  hundred sixty (360) days for the actual number of days elapsed) on the
principal  amount from time to time remaining unpaid hereon from the date hereof
until the Demand Date at "LIBOR" plus three (3) percentage points, commencing on
__________,  1999, and on the first day of each and every month thereafter until
this Note is paid in full,  except that the final  payment of principal  and all
accrued but unpaid interest, if not sooner paid,
shall be due on the Demand Date.

         For purposes of this Note, "LIBOR" means the rate of interest per annum
(rounded upwards, if necessary,  to nearest 1/8 of 1%) at which deposits in U.S.
dollars in immediately  available  funds are being offered to prime banks in the
London interbank market at 11:00 a.m.  (London,  England time),  using the three
(3) month rate,  as  determined  by reference to  Bloomberg  Financial  Market's
terminal screen entitled  "Official BBA LIBOR Fixings" or such other information
vendor  selected  by the holder of this Note for  determining  British  Bankers'
Association Interest Settlement Rates for U.S. Dollar deposits.  Such rate shall
be set and adjusted on the first business day of each calendar quarter and shall
remain  the same and in  effect  for said  calendar  quarterly,  subject  to the
default rate adjustments as hereinafter set forth.

         The  Borrower  shall  have the  right to  prepay,  without  premium  or
penalty,  and to reborrow the revolving  credit hereunder in accordance with the
terms and conditions of the Loan and Security Agreement between the Borrower and
CDWCC (the "Loan Agreement") of even date herewith.

         Upon the  occurrence  of any Event of Default  (as  defined in the Loan
Agreement),  and continuing until this Note is paid in full, and after maturity,
the principal hereof then outstanding  shall bear interest at the rate per annum
determined by adding three percent (3%) to the LIBOR Rate.



 20


         Upon the  occurrence  of an Event of  Default,  this Note and all other
indebtedness of the Borrower to CDWCC shall immediately  become due and payable,
without notice or demand by CDWCC.

         All payments and prepayments on account of the  indebtedness  evidenced
by this Note shall be first applied to costs of collection and any other charges
due  hereunder,  if any,  then on  accrued  and  unpaid  interest  on the unpaid
principal  balance of this Note and the  remainder,  if any,  to said  principal
balance.

         All loans made by CDWCC  against this Note and all payments made by the
Borrower on account of the unpaid principal amount hereof,  shall be recorded on
the books and  records of the holder  hereof and  endorsed  hereon  prior to any
transfer  hereof,  and the  Borrower  agrees  that in any  action or  proceeding
instituted to collect or enforce  collection  of this Note,  the amount shown as
owing on this Note on the books and records of the holder hereof shall be deemed
prima facie correct.

         This Note and any and all other liabilities and obligations of Borrower
to CDWCC,  howsoever  created,  arising or  evidenced,  whether now or hereafter
existing, are secured, inter alia by the Loan Agreement, and all other documents
and  instruments  evidencing  or securing  the loan  evidenced  by this Note are
hereinafter collectively referred to as the "Loan Documents".

         This Note has been executed and delivered in Vernon Hills, Illinois and
shall be construed in accordance with, and governed by, the laws of the State of
Illinois.

         In the event one or more of the provisions contained in this Note shall
for any reason be held to be invalid, illegal or unenforceable in any respect by
a  court   of   competent   jurisdiction,   such   invalidity,   illegality   or
unenforceability  shall not affect any other  provision  of this Note,  and this
Note shall be construed as if such invalid,  illegal or unenforceable  provision
had never been contained herein.

         The Borrower  hereby  irrevocably  waives any right to trial by jury in
any action, suit, counterclaim or proceeding (i) to enforce or defend any rights
under or in connection with this Note, or any amendment, instrument, document or
agreement  delivered  or which may in the  future  be  delivered  in  connection
herewith or therewith,  or (ii) arising from any dispute or controversy  arising
in connection with or related to this Note, or any such  amendment,  instrument,
document or agreement,  and agrees that any such action,  suit,  counterclaim or
proceeding shall be tried before a court and not before a jury.

         The  Borrower  promises  to  pay  all  reasonable  costs  and  expenses
(including reasonable attorneys' fees suffered or incurred by the holder hereof)
in  collecting  this Note or in enforcing  any rights  under the Loan  Agreement
including any collateral granted  thereunder.  The Borrower hereby waives notice
of nonpayment,  presentment for payment, notice of dishonor, and protest of this
Note.



 21


         If payment hereunder  becomes due and payable on a Saturday,  Sunday or
legal  holiday,  the due date thereof  shall be extended to the next  succeeding
business day and  interest  shall be payable  thereon at the  interest  rate set
forth herein

         IN WITNESS WHEREOF,  this Note has been duly executed as of the day and
year first set forth above.
