                 FOR VALUE RECEIVED, BRIDGEVIEW WAREHOUSE, L.L.C., a Delaware
limited liability company (the "Borrower"), hereby promises to pay, within
thirty days of DEMAND therefor in accordance with the terms hereof, to the
order of Trak Auto Corporation, a Delaware Corporation (the "Lender"), at its
Principal Office or such other office as Lender shall notify Borrower the
principal sum of THREE MILLION TWO HUNDRED SEVENTY-SIX THOUSAND U.S. DOLLARS
($3,276,000) (the "Maximum Account") or the then outstanding and unpaid
principal amount hereof, and to pay interest on the unpaid principal amount
hereof from time to time outstanding until paid in full at the interest rate,
at the times and in the manner provided for below.

                 Section 1.  Definitions.  All capitalized terms used herein
and not defined herein shall have the meanings assigned to them in the
Debtors's Fourth Revised Plan of Reorganization (the "Plan") in In re: Trak
Chicago Limited Partnership I, Case No.  95-1-3099-DK (Chapter 11) (U.S. Bankr.
Ct., D. Md., S.D.).  As used herein, the following terms shall have the
following meanings:

                 Advances means the aggregate of (a) the payment made by Lender
to Travelers, on behalf of Borrower, in the amount of $2,000,000.00 which
constitutes the Special Prepayment to Travelers pursuant to Section 6.01 (e) of
the Plan and (b) the payment made by Lender to Dart Group Corporation, on
behalf of Borrower, in the amount of $1,276,000.00 to reimburse Dart Group
Corporation for its payment of that amount to Robert Haft and Linda Haft,
pursuant to Section 8.02.1 of the Plan, as part of the consideration for the
conveyance of the Debtor's Property to Borrower pursuant to the terms of the
Plan.

                 Applicable Federal Rate means for any day, a fluctuating
interest rate per annum equal to the weighted average on the rates of overnight
federal funds transactions with members of the Federal Reserve System arranged
by federal funds brokers, as published for such day (or, if such day is not a
Business Day, for the next preceding Business Day) by the Federal Reserve Bank
of New York and reported in the Wall Street Journal, or if such rate is not so
published for any day that is a Business Day, the rate so published on the next
preceding day that is a Business Day.

                 Business Day means a day other than a Saturday, Sunday or
other day on which commercial banks in Maryland are authorized or required by
law to close.

                 Loan means the aggregate amount of the Advances outstanding at
any one time, made by Lender on behalf of Borrower pursuant to and evidenced by
this Note, which shall not, at any time, exceed the Maximum Amount.

                 Principal Office means the principal office of Lender located
at 3300 75th Avenue, Landover, Maryland 20785.

                 Section 2.  The Loan.  This Note evidences the Loan that
Lender made to Borrower.  Borrower acknowledges and agrees that no provision of
this Note or any other agreement securing or relating to this Note shall be
deemed to impose on Lender any obligation to make any future loans to Borrower
or to affect Lender's unrestricted right to demand payment in full of this Note
at any time.  Borrower may prepay, subject to Section 5 hereof, all or any part
of the Loan, but shall not thereafter be entitled to reborrow same.  The Loan
shall bear interest at the Applicable Federal Rate.

                 Section 3.  Payments.  Lender's demand for payment pursuant to
this Note shall be evidenced by Lender's delivery to Borrower of an executed
Demand Certificate substantially in the form of Exhibit A attached hereto.
Borrower shall be obligated to pay all outstanding principal, interest and
other amounts due under this Note within thirty days of Borrower's receipt of
the executed Demand Certificate; provided, that at any time when the amendment
of the existing Warehouse Lease pursuant to Section 6.03 (a) of the Plan is in
effect, Borrower's obligation to repay this Note will be subject to Lender's
agreement (as set forth in the Demand Certificate) thereafter to pay to
Borrower each month an amount equal to the amount by which Lender's basic rent
obligation for such month under the Warehouse Lease as so amended is less than
the basic rent obligation Lender would have under the Warehouse Lease if it had
not been amended pursuant to Section 6.03 (a) of the Plan.  All payments
hereunder for principal, interest and other amounts shall be made in U.S.
dollars and in immediately available funds, to Lender's Principal Office no
later than 12:00 noon Maryland time on the date when due.  Borrower's
obligation to pay all amounts due hereunder in U.S. dollars shall not be
discharged or satisfied by any tender or recovery pursuant to a judgment, which
is expressed in or converted into any currency other than U.S.  dollars, except
to the extent that such tender or recovery shall result in the actual receipt
by Lender at its Principal Office of the full amount of U.S. dollars payable in
respect of such amounts.  Borrower agrees that its obligation to make payments
in U.S.  dollars shall be enforceable as a separate cause of action if the
amount received by Lender shall fall short of the full amount of U.S. dollars
expressed to be payable hereunder, and shall not be affected by judgment being
obtained for other sums due





                                       2

hereunder.  The provisions of this Section 3 shall survive repayment of the
Loan and cancellation of this Note.

                 Section 4.  Interest.  Borrower agrees to pay interest in
respect of the unpaid principal balance of the Loan outstanding from time to
time, from the date of borrowing until the earlier of maturity (whether by
acceleration or otherwise) or payment in full, at a rate per annum (calculated
on the basis of a 360-day year) equal to the Applicable Federal Rate.  Interest
shall be payable on the last Business Day of each calendar month, and on each
date of repayment or prepayment of all or part of the Loan.

                 Section 5.  Credits.  The amount by which the amendment of the
Warehouse Lease pursuant to Section 6.03 (a) of the Plan causes Lender's
obligation to pay basic rent under the Warehouse Lease to be less each month
after the Effective Date than it would have been if the Warehouse Lease had
remained in effect as prior to the Effective Date, shall be credited each month
against Borrower's obligation to repay the principal amount of this Note and to
pay interest on the outstanding principal balance of this Note.

                 Section 6.  Payment of the Note Prior to Demand.  Borrower may
prepay the outstanding principal of this Note, in whole or in part, at any time
without penalty or premium.  Borrower shall give Lender at least two Business
Days' irrevocable written or telephonic notice of any such payment, specifying
the date and amount of such payment.  The payment amount specified in such
notice shall be due and payable on the date specified, together with the
accrued interest to such date on the amount so paid, and all other amounts then
due.

                 Section 7.  Reliance.  Lender may rely on, and act without
liability upon the basis of, any telephonic or written notice believed by
Lender in good faith to be given to, or received from Borrower, whether or not
Lender subsequently receives from Borrower confirmation thereof.  In each such
case, Borrower hereby waives the right dispute Lender's record of the terms of
such telephonic notice, except to the extent of Lender's gross negligence or
willful misconduct in connection therewith.

                 Section 8.  Miscellaneous.

                 (a) This Note shall be binding on Borrower and its successors,
heirs, executors and assigns and shall inure to the benefit of Lender and its
successor and assigns.  Borrower may not assign or delegate any of its
obligations or agreements hereunder.  No amendment, modification or waiver of
any provision of this Note

                 (c) BORROWER HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY RIGHT TO A JURY TRIAL IN ANY ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO THIS NOTE.  In any action or

Maryland, and agrees that effective service of process may be made on Borrower

its property may have or hereafter acquire immunity, on the grounds of
sovereignty or otherwise, from any judicial process in connection with this
Note, Borrower hereby irrevocably waives, to the fullest extent permitted by
applicable law, any such immunity and agrees not to claim same. Borrower agrees
that a final judgment in any such action or proceeding shall be conclusive, and
may be enforced in any other jurisdiction or in any other permitted manner.

                 (d) BORROWER WAIVES ANY AND ALL REQUIREMENTS OF DEMAND,
PRESENTMENT, PROTEST, NOTICE OF DISHONOR OR FURTHER NOTICE OF ANY KIND IN
CONNECTION WITH THIS NOTE.  Borrower will indemnify and hold Lender harmless
for, and pay in U.S. dollars, all losses, claims, taxes, costs, fees and
expenses, including attorney's fees, incurred by Lender in connection with the
enforcement of this Note by Lender.  This provision shall survive repayment of
the Loan and cancellation of this Note.

collected, withhold or assessed by any jurisdiction, or any department, agency,

provision shall survive repayment of the Loan and cancellation of this Note.
