     This Amendment No. 1 amends and supplements the statement on Schedule 13D
dated December 29, 1997 (the "Schedule 13D"), filed by James River Coal Company,
a Virginia corporation ("JRCC"), relating to the shares of Common Stock, $1.00
per share (the "Common Stock") of Blue Diamond Coal Company, a Delaware
corporation (the "Issuer").  Capitalized terms used herein have the meanings as
set forth in the Schedule 13D unless otherwise defined herein.

Item 3.   Source and Amount of Funds or Other Consideration.
          ------------------------------------------------- 

     On February 13, 1998, JRCC exercised the Option to purchase 470,240 shares
of BDCC Common Stock (the "Shares") from Hamilton as provided for in the Option
Agreement.  JRCC acquired the Shares pursuant to a Stock Purchase Agreement
entered into between JRCC and Hamilton dated as of February 13, 1998 (the
"Purchase Agreement"), a copy of which is attached hereto as Exhibit 1.  JRCC
                                                             ---------       
acquired the Shares with funds provided by a $175,000,000 Credit Agreement among
JRCC, First Union National Bank, as syndicate and documentation agent ("First
Union") and a syndicate of banks party thereto (the "Credit Agreement"), a copy
of which is attached hereto as Exhibit 2.
                               --------- 

Item 4.   Purpose of Transaction.
          ---------------------- 

     On February 11, 1998, BDCC, JRCC and James River Coal MergerSub, Inc., a
wholly owned subsidiary of James River ("MergerSub") entered into an agreement
of Merger (the "Merger Agreement") providing for the merger (the "Merger") of
MergerSub with and into BDCC, a copy of which is incorporated herein by
reference. Pursuant to the terms of the Merger Agreement and at the effective
time of the Merger (the "Effective Time"), each share of Common Stock of BDCC
outstanding prior to the Effective Time (other than the Shares owned by JRCC,
treasury shares which will be canceled and shares as to which appraisal rights
are exercised) will be converted into a right to receive (i) from JRCC, $60.413
in cash (the "Cash Consideration") and (ii) from BDCC, certain contingent
consideration (the "Contingent Consideration") (the Cash Consideration and
Contingent Consideration are referred to collectively herein as the "Merger
Consideration"). The Contingent Consideration will be paid pursuant to a
Contingency Agreement to be entered into immediately prior to the Effective Time
between JRCC, BDCC and Hamilton, (the "Contingency Agreement") which provides
for payments to BDCC shareholders, on a pro rata basis, of 50% of the net value
of the reduction, if any, in BDCC's liability under the Coal Industry Retiree
Health Benefit Act of 1992 (the "Coal Act"), if such reduction is a result of
certain legislative action or formal judicial action occurring within a five
year period following the Effective Time. Upon the Effective Time, BDCC will be
the surviving corporation of the Merger and shall be a wholly owned subsidiary
of JRCC.

     Except as set forth above, neither JRCC, nor to the knowledge of JRCC, any
person listed on Exhibit 4, has any plans or proposals which relate to or would
result in:

     (a)  the acquisition by any person of additional securities of the Issuer,
          or the disposition of securities of the Issuer;

     (b)  an extraordinary corporate transaction, such as a merger,
          reorganization or liquidation, involving the Issuer or any of its
          subsidiaries;

                                      -3-
<PAGE>
 
     (c)  a sale or transfer of a material amount of assets of the Issuer or any
          of its subsidiaries;

     (d)  any change in the present board of directors or management of the
          Issuer, including any plans or proposals to change the number or term
          of directors to fill any existing vacancies on the board;

     (e)  any material change in the present capitalization or dividend policy
          of the Issuer;

     (f)  any other material change in the Issuer's business or corporate
          structure;

     (g)  changes in the Issuer's charter, bylaws or instruments corresponding
          thereto or other actions which may impede the acquisition of control
          of the Issuer by any person;

     (h)  causing a class of securities of the Issuer to be delisted from a
          national securities exchange or to cease to be authorized to be quoted
          in an inter-dealer quotation system of a registered national
          securities association;

     (i)  a class of equity securities of the Issuer to become eligible for
          termination of registration pursuant to Section 12(g)(4) of the
          Securities Exchange Act of 1934; or

     (j)  any action similar to those enumerated above.

     Notwithstanding the foregoing, JRCC may formulate plans or proposals with
respect to one or more of the foregoing in the future.  JRCC and the persons
listed on Exhibit 4 reserve the right to purchase or sell additional shares of
the Common Stock, at any time, without further notice or prior amendment to the
Schedule 13D.  JRCC and the persons listed on Exhibit 4 also reserve the right
to change their intentions with respect to any or all of the foregoing and their
right to act either alone or together with any other person or group.

Item 5.   Interest in Securities of the Issuer.
          ------------------------------------ 

     JRCC currently owns 470,240 shares of Common Stock of the Issuer,
representing approximately 50.3% of the shares of Common Stock of the Issuer
shown as outstanding in the Issuer's Quarterly Report on Form 10-Q for the
period ended December 31, 1997.

                           STOCK PURCHASE AGREEMENT
                           ------------------------

     This STOCK PURCHASE AGREEMENT (the "Agreement"), dated as of February 13,
1998, between HAMILTON HOLDINGS, LTD. (the "Seller"), a Kentucky limited
partnership, and JAMES RIVER COAL COMPANY (the "Purchaser"), a Virginia
corporation, recites and provides:

     WHEREAS, the Seller collectively owns of record and beneficially 470,240
shares of common stock, par value $.01 per share (the "Company Common Stock"),
of Blue Diamond Coal Company, a Delaware corporation (the "Company") (such
Sellers' shares being referred to collectively as the "Shares");

     WHEREAS, the Purchaser and the Seller entered into a proxy and option
agreement, (the "Option Agreement") dated December 15, 1997, pursuant to which
the Seller has agreed, among other things, to sell the Shares to the Purchaser
in exchange for the Purchase Price (as defined below);

     WHEREAS, the Purchaser delivered to the Seller the notice required by
Paragraph 4(a) of the Option Agreement on February 11, 1998 notifying the Seller
that the Purchaser intended to purchase the Shares on the date hereof (the
"Closing Date"); and

     WHEREAS, the Purchaser has previously delivered by wire transfer $1,000,000
in immediately available funds to the Seller as partial payment for the Shares.

     NOW, THEREFORE, in consideration of the mutual promises herein contained
and other good and valuable consideration, receipt whereof is hereby
acknowledged, the Seller and the Purchaser agree as follows:

1.   Sale and Purchase of the Shares.
     --------------------------------

     (a)  Subject to the terms and conditions set forth herein, the Seller
agrees to sell, and the Purchaser agrees to buy, the Shares at a price per Share
equal to the Purchase Price. As payment in full for the Shares, the Purchaser
shall (i) agree to provide for the payment of the Contingency Amount (as defined
below); and (ii) wire transfer to an account designated by the Seller an amount
equal to $27,408,609.12.

     (b)  Simultaneously with the delivery of the Purchase Price, the Seller
shall deliver, assign and convey to the Purchaser a certificate or certificates
representing the Shares purchased by the Purchaser (together with appropriate
stock powers) or provide for the transfer of any shares held in street name by
means reasonably acceptable to Purchaser, free and clear of any and all
mortgages, liens, encumbrances, charges, claims, restrictions, pledges, security
interests or impositions.
<PAGE>
 
     (c)  For purposes of this Agreement, the purchase price per Share (the
"Purchase Price") shall equal the sum of (i) $60.413 in cash plus (ii) the right
to receive after the Closing Date the Contingency Amount (as defined below), if
any, divided by (x) the number of shares of Company Common Stock issued and
outstanding on the date the Company is merged with the wholly owned subsidary of
the Purchaser or (y) the number of shares of Company Common Stock issued and
outstanding on the date the payment becomes due, if such merger does not occur.
For purposes of this Agreement, the contingency amount (the "Contingency
Amount") shall mean the amount to be paid to the shareholders of the Company and
the Seller, pursuant to the Contingency Agreement in the form attached hereto as
Exhibit A. If for any reason the merger between the Company and a wholly-owned
- ---------
Subsidiary of Purchaser does not occur, Purchaser will execute such documents as
may be necessary to convey to Seller its pro rata share of the Contingency
Amount.

2.   Representations and Warranties of the Seller.
     ---------------------------------------------

     The Seller represents and warrants to the Purchaser, as to the Company,
itself and with respect to its Shares, as follows:

     (a)  The Shares constitute all of the shares of Company Common Stock

2,200 shares of Company Common Stock owned by Leo Hamilton.

     (b)  The execution and delivery of this Agreement by the Seller does not,

contract, commitment, agreement, understanding, arrangement or restriction of

other actions on the part of the Seller are required in order to consummate the
transactions contemplated hereby. This Agreement has been duly and validly
executed and delivered by the Seller and, assuming due authorization, execution
and delivery by the Purchaser, constitutes a valid and binding agreement of the
Seller, enforceable against the Seller in accordance with its terms, except to
the extent that enforceability may be limited by applicable bankruptcy,
organization, insolvency, moratorium or other laws affecting the enforcement of
creditors' rights generally and by general principles of equity, regardless of
whether such enforceability is considered in a proceeding in equity or at law.

     (d)  Neither the execution and delivery of this Agreement nor the
performance by the Seller of its obligations hereunder will (i) violate any
order, writ, injunction or judgment

                                      -2-

 applicable to the Seller or (ii) violate any law, decree, statute, rule or
 regulation applicable to the Seller or require any consent, authorization or
 approval of, filing with or notice to, any court, administrative agency or
 other governmental body or authority, other than any required notices or
 filings pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
 as amended, and the rules and regulations promulgated thereunder (the "HSR
 Act") or the federal securities laws.

     (e)  The Seller owns good, valid and marketable title to the Shares, free
and clear of any and all mortgages, liens, encumbrances, charges, claims,
restrictions, pledges, security interests or impositions. Upon delivery of the
Shares to the Purchaser at the closing and upon the Purchaser's payment therefor
in accordance with Section 1 hereto, good and valid title to the Shares, free
and clear of all mortgages, liens, encumbrances, charges, claims, restrictions,
pledges, security interests or impositions, will pass to the Purchaser.

3.   Representations and Warranties of the Purchaser.

     (a)  The Purchaser is (i) duly organized and validly existing and in good
standing under the laws of the Commonwealth of Virginia, (ii) has the requisite
corporate power and authority to execute and deliver this Agreement and to
consummate the transactions contemplated hereby, and (iii) has taken all
necessary corporate action to authorize the execution, delivery and performance
of this Agreement. This Agreement has been duly and validly executed and
delivered by the Purchaser and constitutes the legal, valid and binding
obligation of the Purchaser, enforceable against the Purchaser in accordance
with its terms, except to the extent that enforceability may be limited by
applicable bankruptcy, organization, insolvency, moratorium or other laws
affecting the enforcement of creditors' rights generally and by general
principles of equity, regardless of whether such enforceability is considered in
a proceeding in equity or at law.

     (b)  The execution and delivery of this Agreement by the Purchaser does
not, and the performance by the Purchaser of its obligations hereunder will not,
constitute a violation of, conflict with, or result in a default (or an event

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

     2.1  REVOLVING CREDIT.  Subject to the terms and conditions and relying
          ----------------                                                  
upon the representations and warranties set forth herein, each Lender severally
agrees to make Revolving Credit Loans to the Company from time to time from the
date hereof to but excluding the Commitment Termination Date as requested by the
Company hereunder; provided that (a) the aggregate principal amount of all
outstanding Revolving Credit Loans (after giving effect to any amount requested)
shall not exceed the Aggregate Commitment minus the sum of all outstanding
Swingline Loans and all L/C Obligations, and (b) the principal amount of
outstanding Revolving Credit Loans from any Lender to the Company shall not at
any time exceed such Lender's Commitment minus the sum of such Lender's
Commitment Percentage of all outstanding Swingline Loans and such Lender's
Commitment Percentage of all L/C Obligations. Each Revolving Credit Loan by a
Lender shall be in a principal amount equal to such Lender's Commitment
Percentage of the aggregate principal amount of Revolving Credit Loans requested
on such occasion. Within such limits, the Company may borrow, repay and reborrow
hereunder on or after the date hereof and prior to the Commitment Termination
Date, subject to the terms, provisions and limitations set forth herein.

     2.2  REVOLVING CREDIT LOANS.  (a) The aggregate Revolving Credit Loans made
          ----------------------

     (b)  Each Revolving Credit Loan shall bear interest either at a rate based
on LIBOR or at the Base Rate, as the Company may request subject to and in
accordance with the provisions of Section 3.1.  Each of the Lenders may at its
option fund its Commitment Percentage of any LIBOR Rate Loan by causing a
foreign branch or Affiliate of such Lender to fund such Lender's Commitment
Percentage of such LIBOR Rate Loan, provided that any such exercise of such
option shall not affect the obligation of the Company to repay such Revolving
Credit Loan in accordance with the terms of the Revolving Credit Notes.  Subject
to the other provisions of this Section 2, including the provisions of Section
2.7, and subject to the provisions of Section 3.1(h), Revolving Credit Loans of
more than one Type may be outstanding at the same time.

     2.3  SWINGLINE LOANS.  (a) Subject to the terms and conditions and relying
          ---------------                                                      
upon the representations and warranties set forth herein, the Swingline Lender,
in its individual capacity, agrees to make Swingline Loans to the Company from
time to time from the date hereof to but 

                                      -15-
<PAGE>
 
excluding the Swingline Termination Date as requested by the Company hereunder;
provided that the aggregate principal amount of all outstanding Swingline Loans
(after giving effect to any amount requested) shall not exceed the lesser of (i)
the Aggregate Commitment minus the sum of all outstanding Revolving Credit Loans
and all L/C Obligations, and (ii) the Swingline Commitment.


     (b)(i)  Whenever the Company desires a Swingline Loan advance hereunder, it
shall give telephone notice promptly confirmed in writing to the Swingline
Lender not later than 12:00 noon (Eastern Time) on the Business Day of the
requested Swingline Loan advance.  Each such notice shall be irrevocable and
shall specify (A) that a Swingline Loan advance is requested, (B) the date of
the requested Swingline Loan advance (which shall be a Business Day) and (C) the
principal amount of the Swingline Loan advance requested.  Each Swingline Loan
shall have such maturity date as the Company and the Swingline Lender shall
agree upon receipt by the Swingline Lender of any such notice from the Company.
The Swingline Lender shall initiate the transfer of funds representing the
Swingline Loan advance to the Company by 3:00 p.m. (Eastern Time) on the
Business Day of the requested borrowing.

     (ii)    Each Swingline Loan shall be in a minimum principal amount of
$100,000 and in integral multiples of $50,000 in excess thereof (or the
remaining amount of the Swingline Commitment if less).

     (iv)    The Swingline Lender may, at any time, in its sole discretion, by
written notice to the Company and the Lenders, demand repayment of the
outstanding Swingline Loans by way of an Advance of Revolving Credit Loans, in
which case the Company shall be deemed to have requested an Advance of Base Rate
Loans in the amount of such Swingline Loans; provided that any such demand shall
be deemed to have been given one Business Day prior to the Swingline Termination
Date and on the date of the occurrence of any Event of Default and upon
acceleration of the Obligations under Section 10.2. Each Lender hereby
irrevocably agrees to make its pro rata share of each such Revolving Credit Loan
in the amount, in the manner and on the dates specified in the preceding
sentence notwithstanding (A) the amount of such borrowing may not comply with
the minimum amount of advances for Revolving Credit Loans otherwise required
hereunder, (B) whether any conditions specified in Section 6 are then satisfied,
(C) whether a Default or an Event or Default then exists, (D) failure of any
such request or deemed request for Revolving Credit Loans to be made by the time
otherwise required hereunder, (E) whether the date of such borrowing is a date
on which Revolving Credit Loans are otherwise permitted to be made hereunder, or
(F) any termination of the Commitments. In the event that any Revolving Credit
Loans cannot for any reason be made on the date otherwise required above
(including, without limitation, as a result of the commencement of a proceeding
under the Bankruptcy Code with respect to the Company), each Lender hereby
agrees that it shall forthwith

purchase (as of the date such borrowing would otherwise have occurred, but
adjusted for any payments received from the Company on or after such date and
prior to such purchase) from the Swingline Lender such participations in the
outstanding Swingline Loans as shall be necessary to cause each such Lender to
share in such Swingline Loans ratably based upon its Commitment Percentage;
provided that (A) all interest payable on the Swingline Loans shall be for the
account of the Swingline Lender until the date as of which the respective
participation is purchased, and (B) at the time any purchase of participations
pursuant to this sentence is actually made, the purchasing Lender shall be
required to pay to the Swingline Lender, in accordance with the terms of Section
2.3(c) below, interest on the principal amount of participation purchased for
each day from and including the day upon which such borrowing would otherwise
have occurred to but excluding the date of payment for such participation, at
the rate equal to the Federal Funds Rate.


     (c)  Each Swingline Loan shall bear interest at a rate per annum (computed
on the basis of the actual number of days elapsed over a year of 360 days) equal
to the Swingline Interest Rate as it exists from time to time.  Interest on the
Swingline Loans shall be due and payable on the last day of each calendar
quarter (i.e., each March 31, June 30, September 30 and December 31) and on the

account of the Lenders, on or before the date hereof, an upfront commitment fee
with respect to the Revolving Credit Facility equal to the aggregate of (i) .001
multiplied by the Commitment of each Lender which committed to make its
Commitment available hereunder on or before January 26, 1998, and (ii) .0006
multiplied by the Commitment of each Lender which committed to make its
Commitment available hereunder after January 26, 1998, which upfront commitment
fee will be fully earned and non-refundable once paid.  The Syndication Agent
will, promptly following its receipt thereof, distribute such upfront commitment
fee to the Lenders, with each Lender which committed to make its Commitment
available hereunder on or before January 26, 1998, receiving 

                                      -17-

other than the Swingline Lender, the product of (A) the Unused Commitment Fee
Percentage in effect on the date such installment is due, multiplied by (B) the
daily average amount during the immediately preceding quarter or other period by
which (x) such Lender's Commitment (as it may be reduced from time to time
pursuant to Section 2.6) exceeded (y) the sum of such Lender's Commitment
Percentage of all outstanding Revolving Credit Loans and such Lender's
Commitment Percentage of all outstanding L/C Obligations, multiplied by (C) a
fraction, the numerator of which is the number of days in the immediately
preceding quarter or other period and the denominator of which is 360, and (ii)
in the case of the Swingline Lender, the product of (A) the Unused Commitment
Fee Percentage in effect on the date such installment is due, multiplied by (B)
the daily average amount during the immediately preceding quarter or other

Lender's Commitment Percentage of all outstanding Revolving Credit Loans, the
Swingline Lender's Commitment Percentage of all outstanding L/C Obligations and
all outstanding Swingline Loans, multiplied by (C) a fraction, the numerator of
which is the number of days in the immediately preceding quarter or other period

Unused Commitment Fee to the Lenders ratably in accordance with their respective
shares thereof.

     (c)  The Company shall pay to the Syndication Agent, for its own account,

its entirety, without penalty or premium, provided that the amount of any such
reduction shall be in the amount of $2,000,000 or an integral multiple of
$500,000 in excess thereof.  Such notice of reduction may be in writing or 

                                      -18-
<PAGE>

date of any such reduction or termination, the obligation of the Company to pay
any subsequent installment of the Unused Commitment Fee under Section 2.5(b)
shall thereupon correspondingly be reduced or cease.

     2.7  NOTICE AND MANNER OF BORROWING.  The Company shall give the
          ------------------------------                             
Administrative Agent notice of each requested Advance under this Section 2 as
provided in Section 3.1(a) not later than 12:00 noon (Eastern Time) (i) on the

Administrative Agent in immediately available funds.  On the borrowing date
specified in such notice, the Administrative Agent shall make the Advance by
crediting NationsBank's Commitment Percentage thereof and, to the extent the
Administrative Agent has received such other Lenders' Commitment Percentages
thereof from the other Lenders, such other Lenders' Commitment Percentages
thereof to the general deposit account of the Company maintained with the
Administrative Agent.  The Company acknowledges and agrees that the Lenders'
obligations to make Advances under this Section 2 are several and not joint or

penalty, by giving irrevocable notice to the Administrative Agent not later than
12:00 noon (Eastern Time) on the Business Day on which the prepayment is to
occur in the case of Base Rate Loans and three (3) Business Days prior to the
Business Day on which the prepayment is to occur in the case of LIBOR Rate
Loans, to prepay the Revolving Credit Loans in whole or to make partial
prepayments in the amount of $2,000,000 or any multiple of $500,000 in excess
thereof, at any time, provided that no prepayment may be made on any LIBOR Rate
Loan except on a Payment Date unless at the time such prepayment is made the
Company also pays to the Lenders all losses and out-of-pocket expenses incurred
by the Lenders, or any of them, as a result of such prepayment, including,
without limitation, the excess of (i) the interest that would have been received
from the Company on the amount prepaid during the remaining portion of the
Interest Period in question had the Company not prepaid such LIBOR Rate Loan or
portion thereof, over (ii) the amount of interest which would have accrued on
the amount prepaid if the Lenders had placed such funds on deposit with a prime
bank in the London interbank borrowing market from the date of such prepayment
until the end of such Interest Period, discounted in each case to present value
using the interest rate then existing on U.S. Treasury obligations maturing as
of the end of such Interest Period, as reasonably determined by the
Administrative Agent.

     (b)  If the aggregate principal amount of Revolving Credit Loans
outstanding under this Section 2 at any time exceeds the Aggregate Commitment as
it exists from time to time minus the sum of all outstanding Swingline Loans and
all L/C Obligations, the Company shall, upon the request of any of the Lenders,
immediately prepay the Revolving Credit Loans in an amount sufficient to
eliminate such excess.

     (c)  The Company shall pay each prepayment made under Section 2.8(a) and
Section 2.8(b) to the Administrative Agent for the account of the Lenders. The
Administrative Agent shall, promptly following its receipt of each such
prepayment, distribute it to the Lenders ratably in accordance with their
respective Commitment Percentages.

     2.9  ADJUSTMENTS.  If any Lender (a "Benefitted Lender") shall at any time
          -----------                                                          
receive any payment of all or part of its Revolving Credit Loans, or interest
thereon, or if any Lender shall at any time receive any collateral with respect
to its Revolving Credit Loans (whether voluntarily or involuntarily, by set-off
or otherwise) in a greater proportion than any such payment to and collateral
received by any other Lender, if any, with respect to such other Lender's
Revolving Credit Loans, or interest thereon, such Benefitted Lender shall
purchase for cash from the other Lenders such portion of each such other
Lender's Revolving Credit Loans, or shall provide such other Lenders with the
benefits of any such collateral, or the proceeds thereof, as shall be necessary
to cause such Benefitted Lender to share the excess payment or benefits of such
collateral or proceeds ratably with each of the Lenders; provided that if all or
any portion of such excess payment or benefits is thereafter recovered from such
Benefitted Lender, such purchase shall be rescinded, and the purchase price and
benefits returned to the extent of such recovery, but without interest.  The
Company agrees that each Lender so purchasing a portion of another Lender's
Revolving Credit Loans may exercise all rights of payment (including, without
limitation, rights of set-off) with respect to such portion as fully as if such
Lender were the direct holder of such portion.

     2.10 LIMITATIONS ON ADVANCES.  The Company acknowledges and agrees that (i)
          -----------------------                                               
the Lenders' several obligations to fund advances under this Section 2 shall
terminate on the Commitment Termination Date, and (ii) no Lender shall have any
obligation to fund any portion of any Advance hereunder which would result in
the aggregate amount of Revolving Credit Loans funded by such Lender hereunder
exceeding such Lender's Commitment minus the sum of such Lender's Commitment
Percentage of all outstanding Swingline Loans and such Lender's Commitment
Percentage of all L/C Obligations.

                                                     ---------

case of a Base Rate Advance), and if any portion of such Advance is to be of a

the manner of disbursement. Each Advance shall be in the aggregate principal
amount of $2,000,000, or an integral multiple of $500,000 in excess thereof,
except a Base Rate Advance may be in an amount equal to the unused amount of the
Aggregate Commitment.

     (B)  AFTER AN ADVANCE IS MADE.  The Company may from time to time elect to
          ------------------------

amount of each LIBOR Rate Loan at a rate per annum equal to LIBOR plus the
Applicable LIBOR Margin (with such rate to be reset as of the first day of each
Interest Period and as of the date of each change in the Applicable LIBOR
Margin).  The Administrative Agent, whose determination shall be conclusive
(absent manifest error), shall determine the applicable LIBOR for each Interest
Period and shall notify the Company and each Lender of such LIBOR.  The Company
shall promptly notify the Administrative Agent by telecopy or telephone, and
shall immediately confirm any such telephonic notice in writing, of its

the Advance or outstanding principal balance, as the case may be.

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

or increase of reserve requirements other than those included in the computation
of LIBOR but excluding any income tax on the overall income of the Lenders)
after the date hereof in or in the interpretation of any law or regulation, or
(B) the compliance by the Lenders, or any of them, with any guideline or
directive adopted or otherwise asserted after the date hereof by any central
bank or other Governmental Authority (whether or not having the force of law),
shall result in any actual increase in the cost to the Lenders, or any of them,
of making, funding or maintaining LIBOR Rate Loans or reduce the amount
receivable by the Lenders, or any of them, on any such LIBOR Rate Loans, then
the Company shall from time to time, upon demand by the Lenders, or any of them,

in the interpretation of any law or regulation, or (y) the compliance by the
Lenders, or any of them, with any guideline or directive adopted or otherwise
asserted after the date hereof by any central bank or other Governmental
Authority (whether or not having the force of  law), shall result in any actual
decrease in the cost to the Lenders, or any of them, of making, funding or
maintaining LIBOR Rate Loans or increase the amount receivable by the Lenders,
or any of them, on any such LIBOR Rate Loans, then such Lender or Lenders shall
from time to time reduce the amount payable by the Company to such Lender or
Lenders by the amount of such decrease in cost actually incurred or increase in
amount actually received.  A certificate in reasonable detail as to the amount
of such 

                                      -23-

increased or reduced cost or reduction or increase in amount received and method
of calculation shall be submitted to the Company by the applicable Lender or
Lenders and shall be conclusive absent manifest error.

     (G)  INTEREST ON ADVANCE IF NO NOTICE IS GIVEN OF SELECTION OF INTEREST
          ------------------------------------------------------------------
RATE OPTION. If the Company fails to give the Administrative Agent timely notice
- -----------
of its election to have any Advance bear interest at a rate based on LIBOR or
the Interest Period applicable thereto, such Advance shall automatically bear
interest at the Base Rate.

     (H)  LIBOR CONTRACTS.  At no time may the number of outstanding LIBOR Rate
          ---------------                                                      
Loans exceed five (5).  For purposes of this Section 3.1(h), each Advance,
Revolving Credit Loan or portion of a Revolving Credit Loan bearing interest at
a rate based on LIBOR but with a different Interest Period shall be counted
separately.

     3.2  PAYMENTS AND COMPUTATIONS.  Each payment by the Company hereunder and
          -------------------------                                            
under the Revolving Credit Notes shall be made not later than 12:00 noon
(Eastern Time) on the day when due, in lawful money of the United States of
America and in Federal or other immediately available funds, by payment of such
funds to the Administrative Agent for the account of the Lenders.  The
Administrative Agent shall, promptly following its receipt of each such payment,
distribute it to the Lenders ratably in accordance with their respective
Commitment Percentages.  Amounts received after 12:00 noon (Eastern Time) on any
day shall be deemed received on the next succeeding Business Day. Whenever any
payment to be made under this Agreement or any of the Notes shall be stated to
be due on a day other than a Business Day, except as otherwise provided in the
definition of Interest Period, such payment shall be made on the next succeeding
Business Day and such extension of time shall in such case be included in the
computation of interest.

     3.3  LIBOR INADEQUATE OR UNFAIR.  If before the beginning of any Interest
          --------------------------                                          
Period for any LIBOR Rate Loan, by reason of circumstances affecting the London
interbank market generally, deposits in dollars are not being offered to the
Lenders, or any of them, in amounts approximately equal to the principal amount
of the LIBOR Rate Loan, the Syndication Agent shall forthwith give notice
thereof to the Company, whereupon (unless the Company and the Lenders shall have
agreed on an alternative method of determining the interest rate for such LIBOR
Rate Loan) no further LIBOR Rate Loans shall be made and no outstanding
Revolving Credit Loan or portion thereof shall be converted to a LIBOR Rate Loan
so long as the circumstances giving rise to such notice continue to exist, and
any then outstanding LIBOR Rate Loans shall, as of the expiration of the then
current Interest Period with respect to such LIBOR Rate Loan, be automatically
converted to a Base Rate Loan.

     3.4  CHANGES IN LAW RENDERING A LIBOR LOAN UNLAWFUL.  If, after the date of
          ----------------------------------------------                        
this Agreement, the introduction of, or any change in, any applicable law, rule
or regulation or in the interpretation or administration thereof by any
Governmental Authority charged with the interpretation or administration
thereof, or compliance by the Lenders, or any of them, with any guideline or
directive (whether or not having the force of law) of any such Governmental
Authority, shall make it unlawful or impossible for the Lenders, or any of them,
to make, 

                                      -24-
<PAGE>
 
maintain or fund a LIBOR Rate Loan, the Syndication Agent shall promptly notify
the Company, and the obligation of the Lenders to make, or convert to, a LIBOR
Rate Loan shall forthwith be suspended for the duration of such illegality or
impossibility. Upon such notice, on either (a) the last day of the then current
Interest Period applicable to each such LIBOR Rate Loan if all of the Lenders
may lawfully continue to maintain each such LIBOR Rate Loan to such day or days,
or (b) immediately if any of the Lenders may not lawfully continue to maintain
such LIBOR Rate Loan to such day or days, any LIBOR Rate Loan then outstanding
shall be automatically converted to a Base Rate Loan. If the Company repays any
LIBOR Rate Loans pursuant to clause (b) of this Section 3.4 on a day other than
a Payment Date, it will reimburse each Lender, on demand, for any loss or out-
of-pocket expense incurred by such Lender, in connection with such prepayment.
Such loss or out-of-pocket expense shall include, without limitation, expenses
incurred by such Lender, in connection with the re-employment of the funds
prepaid in an amount equal to the excess of (i) the interest that would have
been received from the Company on the amount so re-employed during the remaining
portion of the Interest Period in question had the Company not prepaid such
LIBOR Rate Loan over (ii) the amount of interest which would have accrued on
such funds if such Lender had placed such funds on deposit with a prime bank in
the London interbank borrowing market from the date of such prepayment until the
end of such Interest Period, discounted in each case to present value using the
interest rate then existing on U.S. Treasury obligations maturing as of the end
of such Interest Period, as reasonably determined by the Syndication Agent. A
certificate in reasonable detail setting forth the calculation of such loss or
expense, including the amount and method of calculation, shall be submitted to
the Company by the Lender or Lenders requesting such reimbursement and, in the
absence of manifest error, shall be conclusive.

     3.5  REIMBURSEMENT AND INDEMNIFICATION.  The Company shall indemnify each
          ---------------------------------                                   
Lender against any reasonable losses or out-of-pocket expenses incurred by such
Lender as a result of (i) any failure by the Company to borrow any LIBOR Advance
after having given notice of its intention to borrow in accordance with Section
3.1 (whether by reason of the Company's election not to proceed or the non-
fulfillment of any of the conditions set forth in this Agreement), (ii) any
payment, prepayment, or conversion of any LIBOR Rate Loan other than on the
Payment Date for such LIBOR Rate Loan, (iii) failure by the Company to pay the
principal amount of any LIBOR Rate Loan when due (whether at the stated
maturity, by reason of acceleration or otherwise), (iv) failure by the Company
to convert an Advance or Revolving Credit Loan or portion thereof into another
Type of Advance or Revolving Credit Loan after having given notice of
conversion, or (v) any failure by the Company to fulfill, on or before the date
specified for such Advance, the applicable conditions set forth in this
Agreement, including without limitation, all such losses and out-of-pocket
expenses incurred by reason of the liquidation or re-employment of deposits or
other funds acquired by such Lender to fund the Advance to be made by such
Lender when such Advance, as a result of such failure, is not made on such date.
A certificate in reasonable detail setting forth the calculation of such loss or
expense, including the amount and method of calculation, shall be submitted to
the Company by the Lender requesting such indemnification and, in the absence of
manifest error, shall be conclusive.

                                      -25-

     3.6  DEFAULT RATE.  Subject to Section 10.3, at the discretion of the
          ------------                                                    
Syndication Agent and the Required Lenders, upon the occurrence and during the
continuance of an Event of Default, (i) no further LIBOR Advances shall be made
and no outstanding Revolving Credit Loan shall be converted to a LIBOR Rate
Loan, (ii) all outstanding LIBOR Rate Loans shall bear interest at a rate per
annum two percent (2%) in excess of the rate that would otherwise be applicable
thereto until the end of the applicable Interest Period and thereafter at a rate
two percent (2%) in excess of the rate then applicable to Base Rate Loans, and
(iii) all outstanding Base Rate Loans shall bear interest at a rate per annum
two percent (2%) in excess of the rate then applicable to Base Rate Loans.

Issuing Lender, in reliance on the agreements of the other Lenders set forth in
Section 4.4(a), agrees to issue letters of credit (the "Letters of Credit") for
the account of the Company or the Company and one or more Subsidiaries on any
Business Day from the date hereof to but excluding the Commitment Termination
Date in such form as may be approved from time to time by the Issuing Lender;
provided that the Issuing Lender shall have no obligation to issue any Letter of
Credit if, after giving effect to such issuance, the L/C Obligations would
exceed the lesser of (i) the Aggregate Commitment less the sum of all
outstanding Revolving Credit Loans and all outstanding Swingline Loans and (ii)
the L/C Commitment less the L/C Obligations attributable to the Existing
NationsBank Letters of Credit.  Each Letter of Credit shall (i) be denominated
in United States Dollars in a minimum amount of $50,000, (ii) be a standby
letter of credit issued to support the Contingency Amount or obligations of the
Company or the Company and one or more of its Subsidiaries, contingent or
otherwise, with respect to environmental and insurance matters and other
corporate purposes incurred in the ordinary course of business, (iii) expire on
a date satisfactory to the Issuing Lender, which date shall be no later than the
Commitment Termination Date and (iv) be subject to the Uniform Customs and, to
the extent not inconsistent therewith, the laws of the Commonwealth of Virginia.
The Issuing Lender shall not at any time be obligated to issue any Letter of
Credit hereunder if such issuance would conflict with, or cause the Issuing
Lender or any L/C Participant to exceed any limits imposed by, any applicable
law.  References herein to "issue" and derivations thereof with respect to
Letters of Credit shall also include extensions or modifications of any existing
Letters of Credit, unless the context otherwise requires.

time to time request that the Issuing Lender issue a Letter of Credit by

satisfaction of the Issuing Lender, and such other certificates, documents and
other papers and information as the Issuing Lender may request.  Upon receipt of
any L/C Application, the Issuing Lender shall process such L/C Application and
the certificates, documents and other papers and information delivered to it in
connection therewith in accordance with its customary procedures and shall,
subject to Section 4.1 and Section 6, promptly issue the Letter of Credit

<PAGE>
 
Lender be required to issue any Letter of Credit earlier than three (3) Business
Days after its receipt of the L/C Application therefor and all such other
certificates, documents and other papers and information relating thereto) by

otherwise may be agreed by the Issuing Lender and the Company. The Issuing
Lender shall furnish to the Company a copy of such Letter of Credit and furnish
to each Lender a copy of such Letter of Credit and the amount of each Lender's

Letter of Credit, times (ii) the L/C Fee in effect on the day such annual
installment is due; provided that, if the remaining term of such Letter of
Credit on the date any installment of the annual letter of credit commission is

thereunder. Each L/C Participant unconditionally and irrevocably agrees with the
Issuing Lender that, if a draft is paid under any Letter of Credit for which the
Issuing Lender is not reimbursed in full by the Company in accordance with the
terms of this Agreement, such L/C Participant shall pay to the Issuing Lender
upon demand an amount equal to such L/C Participant's Commitment Percentage of
the amount of such draft, or any part thereof, which is not so reimbursed.

     (B)  PAYMENTS BY L/C PARTICIPANTS.  Upon becoming aware of any amount
          ----------------------------

Section 4.4(a) in respect of any unreimbursed portion of any payment made by the
Issuing Lender under any Letter of Credit, the Issuing Lender shall notify each
L/C Participant of the amount and due date of such required payment and such L/C
Participant shall pay to the Issuing Lender the amount specified on the

of the unreimbursed amounts described in this Section 4.4(b), if the L/C
Participants receive notice that any such payment is due (A) prior to 1:00 p.m.
(Eastern Time) on any Business Day, such payment shall be due that Business Day,
and (B) after 1:00 p.m. (Eastern Time) on any Business Day, such payment shall

has made payment under any Letter of Credit and has received from any L/C
Participant its Commitment Percentage of such payment in accordance with this
Section 4.4, the Issuing Lender receives any payment related to such Letter of

          ---------------------------------------                        
reimburse the Issuing Lender on each date on which the Issuing Lender notifies
the Company of the date and amount of a draft paid under any Letter of Credit
for the amount of (a) such draft so paid and (b) any taxes, fees, charges or
other costs or expenses reasonably incurred by the Issuing Lender in connection
with such payment.  Each such payment shall be made to the Issuing Lender at its
address for notices specified herein in lawful money of the United States and in
immediately available funds.  Interest shall be payable on any and all amounts
remaining unpaid by the Company under this Section 4 from the date such amounts
become payable (whether at stated maturity, by acceleration or otherwise) until
payment in full at the rate which would be payable on any outstanding Base Rate
Loan which was then overdue.  If the Company fails to timely reimburse the
Issuing Lender on the date the Company receives the notice referred to in this
Section 4.5, the Company shall be deemed to have timely given a Notice of
Borrowing hereunder to the Administrative Agent requesting the Lenders to make a
Base Rate Loan on such date in an amount equal to the amount of such drawing
and, regardless of whether or not the conditions precedent specified in Section
6 have been satisfied, the Lenders shall make Revolving Credit Loans in such
amount, the proceeds of which shall be applied to reimburse the Issuing Lender
for the amount of the related drawing and costs and expenses.

shall be absolute and unconditional under any and all circumstances and
irrespective of any set-off, counterclaim or defense to payment which the
Company may have or have had against the Issuing Lender or any beneficiary of a
Letter of Credit.  The Company also agrees with the Issuing Lender that the
Issuing Lender shall not be responsible for, and the Company's reimbursement
obligation under Section 4.5 shall not be affected by, among other things, the
validity or genuineness of documents or of any endorsements thereon, even though
such documents shall in fact prove to be invalid, fraudulent or forged, or any
dispute between or among the Company and any beneficiary of any Letter of Credit
or any other party to which such Letter of Credit may be transferred or any
claims whatsoever of the Company against any beneficiary of such Letter of
Credit or any such transferee.  The Issuing Lender shall not be liable for any
error, omission, interruption or delay in transmission, dispatch or delivery of
any message or advice, however transmitted, in connection with any Letter of
Credit, except for errors or omissions caused by the Issuing Lender's gross
negligence or willful misconduct. The Company agrees that any action taken or
omitted by the Issuing Lender under or in connection with any Letter of Credit
or the related drafts or documents, if done in the absence of gross negligence
or willful misconduct and in accordance with the standards of care specified in
the Uniform Customs and, to the extent not inconsistent therewith, the UCC shall
be binding on the Company and shall not result in any liability of the Issuing
Lender to the Company.  The responsibility of the Issuing Lender to the Company
in connection with any draft presented for payment under any Letter of Credit
shall, in addition to any payment obligation expressly provided for in such
Letter of Credit, be limited to determining that the documents (including each
draft) delivered under such Letter of Credit in connection with such presentment
are in conformity with such Letter of Credit.

are complete and correct and fairly present the Consolidated financial condition
of the Company and its Subsidiaries and the Consolidated results of operations
and cash flows as of the date and for the periods referred to therein and have
been prepared in accordance with GAAP.  There are no material liabilities,
direct or indirect, fixed or contingent, of the Company or any of its

certificate or statement furnished to the Lenders, or any of them, in writing by
or on behalf of the Company in connection herewith contains any untrue statement
of a material fact or omits to state a material fact necessary in order to make
the statements contained herein and therein not misleading.  Although the

2006, and the proforma Consolidated statement of changes in financial position

incorporated) under common control which, together with the Company or any of
its Subsidiaries covered by ERISA, are treated as a single employer under

constitute grounds for the complete termination of any such plan by the PBGC or
for the appointment of any trustee to administer any such plan by the
appropriate United States District Court and which could have a material adverse
effect on the Company or its ability to perform its obligations hereunder.

     5.11 TAXES.  Except as disclosed on Schedule 5.11, each of the Company and

default under any instrument under or subject to which any such indebtedness has
been incurred, and no event has occurred under the provisions of any such
instrument which, with the giving of notice or the lapse of time, or both, would
constitute an event of default thereunder.

         ---------------------------------------                               
interest on the Loans, the Notes and the Reimbursement Obligations at the time
outstanding, and all other amounts owed to the Lenders and to the Syndication
Agent, the Documentation Agent and the Administrative Agent under this Agreement
or any of the other Loan Documents (including, without limitation, all L/C
Obligations, whether or not the beneficiaries of the then outstanding Letters of
Credit shall have presented the documents required thereunder) and all other
Obligations, to be forthwith due and payable, whereupon the same shall
immediately become due and payable without presentment, demand, protest or other
notice of any kind, all of which are expressly waived, anything in this
Agreement or the other Loan Documents to the contrary notwithstanding, and
terminate the Credit Facilities and each of the Commitments and any right of the
Company to request borrowings or Letters of Credit thereunder; provided that
upon the occurrence of an Event of Default specified in Section 10.1(h), the

automatically become due and payable.

     (B) LETTERS OF CREDIT.  With respect to all Letters of Credit with respect
         -----------------

acceleration pursuant to the preceding paragraph, require the Company at such
time to deposit in a cash collateral account opened by the Syndication Agent an
amount equal to the aggregate then undrawn and unexpired amount of such Letters
of Credit.  Amounts held in such cash collateral account shall be applied by the
Syndication Agent to the payment of drafts drawn under such Letters of Credit,
and the unused portion thereof after all such Letters of Credit shall have
expired or been fully drawn upon, if any, shall be applied to repay the other
Obligations.  After all such Letters of Credit shall have expired or been fully
drawn upon and all Obligations shall have been satisfied and paid in full, the

          -----------------------------------------------                     
the rights and remedies of the Syndication Agent and the Lenders set forth in
this Agreement is not intended to be exhaustive and the exercise by the
Syndication Agent and the Lenders of any right or remedy shall not preclude the
exercise of any other rights or remedies, all of which shall be cumulative, and
shall be in addition to any other right or remedy given hereunder or under the
Loan Documents or that may now or hereafter exist in law or in equity or by suit
or otherwise.  No delay or failure to take action on the part of the Syndication
Agent or any Lender in exercising any right, power or privilege shall operate as
a waiver thereof, nor shall any single or partial exercise of any such right,
power or privilege preclude other or further exercise thereof or the exercise of
any other right, power or privilege or shall be construed to be a waiver of any
Event of Default.  No course of dealing between the Company, the Syndication
Agent and the Lenders or their respective agents or employees shall be effective
to change, modify or discharge any provision of this Agreement or any of the
other Loan Documents or to constitute a waiver of any Event of Default.

Administrative Agent, as the case may be, by the terms of this Agreement and
such other Loan Documents, together with such other powers as are reasonably
incidental thereto.  Notwithstanding any provision to the contrary elsewhere in
this Agreement or such other Loan Documents, neither the Syndication Agent, the
Documentation Agent nor the Administrative Agent shall have any duties or
responsibilities, except those expressly set forth herein and therein, or any
fiduciary relationship with any Lender, and no implied covenants, functions,

report, statement or other document referred to or provided for in, or received
by the Syndication Agent, the Documentation Agent or the Administrative Agent,
as the case may be, under or in connection with this Agreement or the other Loan
Documents or for the value, validity, effectiveness, genuineness, enforceability
or sufficiency of this Agreement or the other Loan Documents or for any failure
of the Company or any of its Subsidiaries to perform its obligations hereunder
or thereunder.  Neither the Syndication Agent, the Documentation Agent nor the
Administrative Agent shall be under any obligation to any Lender to ascertain or
to inquire as to the observance or performance of any of the agreements
contained in, or conditions 

                                      -49-

of, this Agreement, or to inspect the properties, books or records of the
Company or any of its Subsidiaries.

     11.4 RELIANCE BY THE AGENTS.  Each of the Syndication Agent, the
          ----------------------                                     
Documentation Agent and the Administrative Agent shall be entitled to rely, and
shall be fully protected in relying, upon any note, writing, resolution, notice,
consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or
teletype message, statement, order or other document or conversation believed by
it to be genuine and correct and to have been signed, sent or made by the proper
Person or Persons and upon advice and statements of legal counsel (including,
without limitation, counsel to the Company), independent accountants and other
experts selected by such Agent.  Each of the Syndication Agent, the
Documentation Agent and the Administrative Agent may deem and treat the payee of
any Revolving Credit Note as the owner thereof for all purposes unless such
Revolving Credit Note shall have been transferred in accordance with Section
12.10. Each of the Syndication Agent, the Documentation Agent and the
Administrative Agent shall be fully justified in failing or refusing to take any
action under this Agreement and the other Loan Documents unless it shall first
receive such advice or concurrence of the Required Lenders (or, when expressly
required hereby or by the relevant other Loan Document, all the Lenders) as it
deems appropriate or it shall first be indemnified to its satisfaction by the
Lenders against any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action except for its own gross
negligence or willful misconduct.  Each of the Syndication Agent, the
Documentation Agent and the Administrative Agent shall in all cases be fully
protected in acting, or in refraining from acting, under this Agreement and the
Revolving Credit Notes in accordance with a request of the Required Lenders (or,

Agent nor the Administrative Agent shall be deemed to have knowledge or notice
of the occurrence of any Default or Event of Default hereunder unless it has
received notice from a Lender or the Company referring to this Agreement,
describing such Default or Event of Default and stating that such notice is a
"notice of default."  In the event that the Syndication Agent receives such a
notice, it shall promptly give notice thereof to the Lenders.  The Syndication
Agent shall take such action with respect to such Default or Event of Default as
shall be reasonably directed by the Required Lenders; provided that unless and
until the Syndication Agent shall have received such direction, the Syndication
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem advisable in the best interests of the Lenders.

     11.6 NON-RELIANCE ON THE AGENTS AND OTHER LENDERS.  Each Lender expressly
          --------------------------------------------                        
acknowledges that neither the Syndication Agent, the Documentation Agent nor the
Administrative Agent or any of their respective officers, directors, employees,
agents, attorneys-in-fact, Subsidiaries or Affiliates has made any
representations or warranties to it and that no act by the Syndication Agent,
the Documentation Agent or the Administrative Agent hereinafter taken, including
any review of the affairs of the Company or any of its Subsidiaries, shall be

                                      -50-
<PAGE>
 
deemed to constitute any representation or warranty by the Syndication Agent,
the Documentation Agent or the Administrative Agent to any Lender.  Each Lender
represents to the Syndication Agent, the Documentation Agent and the
Administrative Agent that it has, independently and without reliance upon the
Syndication Agent, the Documentation Agent, the Administrative Agent or any
other Lender, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, financial and other condition and creditworthiness of the
Company and its Subsidiaries and made its own decision to make its Revolving
Credit Loans, participate in Swingline Loans and issue or participate in Letters
of Credit hereunder and enter into this Agreement.  Each Lender also represents
that it will, independently and without reliance upon the Syndication Agent, the
Documentation Agent, the Administrative Agent or any other Lender, and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Loan Documents, and to make
such investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Company and its Subsidiaries.  Except for notices, reports and other documents
expressly required to be furnished to the Lenders by the Syndication Agent, the
Documentation Agent or the Administrative Agent hereunder or by the other Loan
Documents, neither the Syndication Agent, the Documentation Agent nor the
Administrative Agent shall have any duty or responsibility to provide any Lender
with any credit or other information concerning the business, operations,
property, financial and other condition or creditworthiness of the Company or
any of its Subsidiaries which may come into the possession of the Syndication
Agent, the Documentation Agent or the Administrative Agent or any of their
respective officers, directors, employees, agents, attorneys-in-fact,
Subsidiaries or Affiliates.

     11.7 INDEMNIFICATION.  The Lenders agree to indemnify the Syndication

Agent, the Documentation Agent and the Administrative Agent in their respective
capacities (to the extent not reimbursed by the Company and without limiting the
obligation of the Company to do so), ratably according to the respective amounts
of their Commitment Percentages, from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind whatsoever which may at any time
(including, without limitation, at any time following the payment of the Notes
or any Reimbursement Obligation) be imposed on, incurred by or asserted against
the Syndication Agent, the Documentation Agent or the Administrative Agent, as
the case may be, in any way relating to or arising out of this Agreement or the
other Loan Documents, or any documents contemplated by or referred to herein or
therein or the transactions contemplated hereby or thereby or any action taken
or omitted by the Syndication Agent, the Documentation Agent or the
Administrative Agent under or in connection with any of the foregoing; provided
that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting solely from the bad faith, gross
negligence or willful misconduct of the Syndication Agent, the Documentation
Agent or the Administrative Agent.  The agreements in this Section 11.7 shall

     11.8 THE AGENTS IN THEIR INDIVIDUAL CAPACITIES.  The Syndication Agent, the
          -----------------------------------------                             
Documentation Agent and the Administrative Agent and their respective
Subsidiaries and Affiliates may make loans to, accept deposits from and
generally engage in any kind of business with the Company as though the
Syndication Agent, the Documentation Agent and the Administrative Agent were not
Agents hereunder.  With respect to any Loans made or renewed by it and any Note
issued to it and with respect to any Letter of Credit issued by it or
participated in by it, the Syndication Agent, the Documentation Agent and the
Administrative Agent shall have the same rights and powers under this Agreement
and the other Loan Documents as any Lender and may exercise the same as though
it were not an Agent, and the terms "Lender" and "Lenders" shall include the
Syndication Agent, the Documentation Agent and the Administrative Agent in their
individual capacities.

     11.9 RESIGNATION OF THE AGENTS; SUCCESSOR AGENTS.  Subject to the
          -------------------------------------------                 
appointment and acceptance of a successor as provided below, the Syndication
Agent, the Documentation Agent and/or the Administrative Agent may resign at any
time by giving notice thereof to the Lenders and the Company.  Upon any such
resignation, the Required Lenders, with the approval of the Company as long as
no Default or Event of Default has occurred and is continuing (which approval of
the Company shall not be unreasonably withheld), shall have the right to appoint
a successor Syndication Agent, Documentation Agent and/or Administrative Agent,
as the case may be, which successor shall have minimum capital and surplus of at
least $500,000,000.  If no successor Agent shall have been so appointed by the
Required Lenders and shall have accepted such appointment within thirty (30)
days after any Agent's giving of notice of resignation, then the applicable
Agent may, on behalf of the Lenders, with the approval of the Company as long as
no Default or Event of Default has occurred and is continuing (which approval of
the Company shall not be unreasonably withheld), appoint a successor Agent,
which successor shall have minimum capital and surplus of at least $500,000,000.
Upon the acceptance of any appointment as Agent hereunder by a successor Agent,
such successor Agent shall thereupon succeed to and become vested with all
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder.  After any
retiring Agent's resignation hereunder as Agent, the provisions of this Section
11 shall continue in effect for its benefit with respect to any actions taken or
omitted to be taken by it while it was acting as Agent.

                            MISCELLANEOUS PROVISIONS
                            ------------------------

     12.1 CAPITAL ADEQUACY.  If any of the Lenders shall have determined that
          ----------------                                                   
the adoption after the date hereof of any applicable law, rule or regulation
regarding capital adequacy, or any change therein after the date hereof, or any
change after the date hereof in the interpretation or administration thereof by
any Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by such Lender (or any
lending office of such Lender) or its holding company or any successor
corporation owning all or substantially all of the capital stock of such Lender
("its Parent") with any guideline or directive adopted after the date hereof
regarding capital adequacy (whether or not having the force of law) of any such
Governmental Authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on such Lender's capital or the capital of
its Parent as a consequence of its obligations hereunder to a level below that
which such Lender (or its Parent) could have achieved but for such adoption,
change or compliance by an amount deemed by such Lender to be material, then
from time to time, within fifteen (15) days after demand by such Lender, the
Company shall pay to such Lender such additional amount or amounts as will
compensate such Lender (or its Parent) for such reduction.  Within fifteen (15)
days of the date that such Lender determines that it will invoke the provisions
of this Section 12.1, it will present its demand to the Company in a certificate
claiming compensation under this Section 12.1 which shall be accompanied by the
calculations supporting such claim.  In addition, such Lender shall supply to
the Company such supporting information relating to such claim as the Company
may reasonably request.

(b) the Syndication Agent shall have declared any or all of the Obligations to

     12.5 GOVERNING LAW.  This Agreement, the Notes and the other Loan

thereof.

     12.6 CONSENT TO JURISDICTION.  The Company hereby irrevocably consents to
          -----------------------                                             
the personal jurisdiction of the state and federal courts located in the City of

the Notes and the other Loan Documents, any rights or obligations hereunder or

hereby irrevocably consents to the service of a summons and complaint and other

right of the Syndication Agent or any Lender to serve legal process in any other

     12.7 BINDING ARBITRATION; WAIVER OF JURY TRIAL.
          ----------------------------------------- 

          (a) BINDING ARBITRATION.  Upon demand of any party hereto, whether
              -------------------                                               
made before or after institution of any judicial proceeding, any dispute, claim
or controversy arising out of, in connection with or relating to this Agreement,
the Notes or any other Loan Document ("Disputes"), between or among parties
hereto or thereto shall be resolved by binding arbitration as provided herein.
Institution of a judicial proceeding by a party does not waive the right of that
party to demand arbitration hereunder. Disputes may include, without limitation,
tort claims, counterclaims, disputes as to whether a matter is subject to
arbitration, claims brought as class actions, claims arising from documents
executed in the future, or claims arising out of or connected with the
transactions contemplated by this Agreement or any of the Loan Documents.
Arbitration shall be conducted under and governed by the Commercial Financial
Disputes Arbitration Rules (the "Arbitration Rules") of the American Arbitration
Association (the "AAA"), as in effect from time to time, and Title 9 of the U.S.
Code, as amended. All arbitration hearings shall be conducted in Richmond,
Virginia. The expedited procedures set forth in Rule 51, et seq. of the 
                                                         -------       
Arbitration Rules shall be applicable to claims of less than $1,000,000.  All

                                      -56-
<PAGE>
 
applicable statutes of limitation shall apply to any Dispute. A judgment upon
the award may be entered in any court having jurisdiction. The panel from which
all arbitrators are selected shall be comprised of licensed attorneys. The
single arbitrator selected for expedited procedure shall be a retired judge from
the highest court of general jurisdiction, state or federal, of the state where
the hearing will be conducted, or if such person is not available, the single
arbitrator may be a licensed attorney. Notwithstanding the foregoing, this
arbitration provision does not apply to Disputes under and related to any
interest rate protection agreements.

     (b)  Notwithstanding the preceding binding arbitration provisions, the
Company, the Agents, and the Lenders agree to preserve, without diminution,
certain remedies, more particularly described below, that any party hereto may
employ or exercise freely, independently, or in connection with an arbitration
proceeding or after an arbitration action is brought. The Company, the Agents
and the Lenders shall have the right to proceed in any court of proper
jurisdiction or by self-help to exercise or prosecute the following remedies, as
applicable: (i) all rights to foreclose against any real or personal property or
other security by exercising a power of sale granted under any Loan Documents or
under applicable law or by judicial foreclosure and sale, including a proceeding
to confirm the sale; (ii) all rights of self-help including peaceful occupation
of real property and collection of rents, setoff, and peaceful possession of
personal property; (iii) obtaining provisional or ancillary remedies including
injunctive relief, sequestration, garnishment, attachment, appointment of
receiver and filing an involuntary bankruptcy proceeding; and (iv) when
applicable, a judgment by confession of judgment. Preservation of these remedies
does not limit the power of any arbitrator to grant similar remedies that may be
requested by a party in a Dispute.

     (c)  WAIVER OF JURY TRIAL.  TO THE FULLEST EXTENT PERMITTED BY LAW, THE
          --------------------                                              
SYNDICATION AGENT, THE DOCUMENTATION AGENT, THE ADMINISTRATIVE AGENT, EACH
LENDER AND THE COMPANY HEREBY IRREVOCABLY WAIVE THEIR RESPECTIVE RIGHTS TO A
JURY TRIAL WITH RESPECT TO ANY ACTION, CLAIM OR OTHER PROCEEDING ARISING OUT OF
ANY DISPUTE IN CONNECTION WITH THIS AGREEMENT, THE NOTES OR THE OTHER LOAN
DOCUMENTS, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THEREUNDER, OR THE PERFORMANCE
OF SUCH RIGHTS AND OBLIGATIONS.

     12.8 INJUNCTIVE RELIEF; PUNITIVE DAMAGES.
          ----------------------------------- 

     (a)  The parties recognize that, in the event any party fails to perform,
observe or discharge any of its obligations or liabilities under this Agreement,
any remedy of law may prove to be inadequate relief. Therefore, (i) the Company
agrees that the Lenders, at the Lenders' option, shall be entitled to temporary
and permanent injunctive relief upon any such failure of the Company without the
necessity of proving actual damages, and (ii) the Lenders agree that the
Company, at the Company's option, shall be entitled to temporary and permanent
injunctive relief upon any such failure of the Lenders without the necessity of
proving actual damages.

     (b)  The Syndication Agent, the Documentation Agent, the Administrative
Agent, the Lenders and the Company (on behalf of itself and its Subsidiaries)
hereby agree that no such Person 

                                      -57-
<PAGE>
 
shall have a remedy of punitive or exemplary damages against any other party to
a Loan Document and each such Person hereby waives any right or claim to
punitive or exemplary damages that they may now have or may arise in the future
in connection with any dispute.

     12.9   ACCOUNTING MATTERS.  All financial and accounting calculations,
            ------------------                                             
measurements and computations made for any purpose relating to this Agreement,
including, without limitation, all computations utilized by the Company or any
Subsidiary thereof to determine compliance with any covenant contained herein,
shall, except as otherwise expressly contemplated hereby or unless there is an
express written direction by the Syndication Agent to the contrary agreed to by
the Company, be performed in accordance with GAAP as in effect on the date of
this Agreement. In the event that changes in GAAP shall be mandated by the
Financial Accounting Standards Board, or any similar accounting body of
comparable standing, or shall be recommended by the Company's certified public
accountants, to the extent that such changes would modify such accounting terms
or the interpretation or computation thereof, such changes shall be followed in
defining such accounting terms only from and after the date the Company and the
Lenders shall have amended this Agreement to the extent necessary to reflect any
such changes in the financial covenants and other terms and conditions of this
Agreement.
