                           REPLACEMENT COMMERCIAL NOTE

____________, 1999                                              $35,000,000.00
                                                                  Commitment

                  FOR VALUE RECEIVED, the undersigned (the "Maker"),
unconditionally promises to pay to the order of ___________________ (the
"Bank"), without offset, at the Bank's office in Norfolk, Virginia, or at such
other place as the Bank may designate, all sums advanced hereunder pursuant to
the Credit Agreement (as hereinafter defined), with interest payable on the
first day of each month beginning February 1, 1999, and at maturity, on the
unpaid principal balance of such sums from the date of each advance until repaid
in full. If not earlier paid, the aggregate amount of all sums outstanding, set
forth below in the last entry on the Schedule of Advances and Payments set forth
below as "Principal Amount Outstanding," together with interest shall be paid in
full on such date as is provided for in the Credit Agreement, dated June 20,
1997, as amended, by and among the Maker and Wachovia Bank, N.A., Bank of
America, N.A. d/b/a NationsBank, N.A., successor to NationsBank, N.A., Crestar
Bank and First Union National Bank (successor in interest to Signet Bank), as
Lenders (the "Credit Agreement"). Capitalized terms used herein and not
otherwise defined shall have the meaning assigned to them in the Credit
Agreement.

                  All payments made on this Note may be applied, at the Bank's
option first to unpaid commitment fees and costs of collection, if any, then to
accrued interest, then to principal and then to other fees.

                  The Bank may, but shall not be required to, enter all advances
and payments on this Note in the Schedule of Advances and Payments set forth
below. In no event shall the principal sum set forth below in the last entry on
the Schedule as "Principal Amount Outstanding" exceed the Bank's Commitment. The
aggregate Principal Amount Outstanding shown on the Schedule shall be prima
facie evidence of the principal amount owing and unpaid on this Note. The
failure to record the date and amount of any advance on the Schedule shall not,
however, limit or otherwise affect the obligations of the Maker under this Note
to repay the principal amount of the advance together with all interest accruing
thereon.

                  Interest on this Note shall accrue at the rate per annum set
forth in the Credit Agreement.

                  It is understood and agreed that any officer or authorized
employee of the Bank may make entries on the Schedule and on any additional
schedules attached hereto upon receipt of written or telephonic instructions of
anyone reasonably believed by the Bank to be an authorized officer or agent of
the Maker; provided that, in the case of initial borrowings hereunder and
increases in the principal amount of borrowings, the amount of such borrowings
shall have been credited to the account of the Maker or otherwise delivered to
the Maker. Upon written or telephonic instructions of anyone reasonably believed
by the Bank to be an authorized officer or agent of the Maker, the Bank may
charge Maker's account with the Bank and apply funds therefrom to the payment of
interest, principal, or late charges due under this Note. The Maker shall
indemnify and hold the Bank harmless from and against any and all claims,


                                       60
<PAGE>

damages, losses, costs and expenses (including attorney's fees) which may arise
or be created by the acceptance of instructions for making or paying advances by
telephone. This Note is issued pursuant to the Credit Agreement. The Maker and
Bank shall have the rights and obligations set forth in this Note and the Credit
Agreement, including any amendments thereto and any renewals or substitutions
thereof.

                  This Note is secured by the Collateral.

                  The happening of any of Event of Default shall constitute an
event of default hereunder.

                  Upon the  happening  of any event of default  under this Note,
the Bank may exercise its  remedies  available  to it under the Credit
Agreement  and any other rights available to it at law or in equity.

                  If Maker fails to pay any installment of principal and/or
interest within seven (7) days of its due date as set forth in the Credit
Agreement, or otherwise fails to repay this Note within seven (7) days of its
due date, the Maker agrees to pay the Bank on demand a late charge of five
percent (5%) of the overdue payment. The Bank may, at its option, apply any late
payments (either full or partial) in the following manner: first to interest,
then to principal and finally to any late charges.

                  Maker hereby expressly waives presentment, demand, protest and
notice of dishonor, and agrees that this Note may be renewed one or more times
and any extension or extensions of the time of payment of this Note may be made
before, at, or after maturity for periods in excess of the original term of this
Note; waives any right which it may have to require the Bank to proceed against
any other Person or any property securing this Note; agrees that its liability
hereunder shall not be affected or impaired by any failure, neglect or omission
of Bank to exercise any remedies of set-off or otherwise that it may have or by
any determination that any security interest or lien taken by the Bank to secure
this Note is invalid or unperfected.

                  The Bank shall have, but shall not be limited to, the
following rights, each of which may be exercised at any time: to pledge or
transfer this Note and the Collateral, and any pledgee or transferee shall have
all of the rights of the Bank and the Bank shall thereafter be relieved from any
liability with respect to any Collateral so pledged or transferred; and after an
Event of Default, to transfer the whole or any part of the Collateral into the
name of itself or its nominee.

                  Maker agrees to remain liable to the Bank for any deficiency.
Any Collateral, and any surplus after sale, may be returned to Maker, but if
after sale of the Collateral any obligation or liability of Maker or any
guarantor to the Bank is contingent or not due, the Bank may retain such
proceeds as additional security for such obligation or liability. The Bank may
continue to hold any Collateral after payment of this Note if at any time of
payment or any discharge hereof Maker shall be then directly or contingently
liable to the Bank pursuant to the Credit Agreement or any of the Loan Documents
whether or not such obligation is due, and the Bank may thereafter exercise all
rights with respect to such Collateral granted therein even though this Note
shall have been surrendered to Maker. Any proceeds of any of the Collateral
received by the Bank may be applied by the Bank to the payment of expenses
incurred in connection with the


                                       61
<PAGE>

Collateral, including attorneys' fees and legal expenses, and any balance of
such proceeds may be applied by the Bank toward the payment of this Note and all
other liabilities, and in such order of application as the Bank may from time to
time elect.

                  The term "Bank" used herein shall include any future holder of
this Note or any agent acting on behalf of the Bank. This Note shall be governed
and construed in accordance with the laws of the Commonwealth of Virginia.
Whenever 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 invalid under such law, such provision
shall be ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
Note. This Note shall apply to and bind Maker's successors and assigns and shall
inure to the benefit of the Bank and its successors and assigns.
