Initial Loans made by each of the Lenders and each repayment in respect of the

and the Lenders shall treat each Person whose name is recorded in the Register
as the owner of an Initial Loan or other obligation hereunder as the owner
thereof for all purposes of this Agreement and the other Credit Documents,

such Loans, Borrower shall at such time pay all expenses and costs required by

          Notwithstanding the foregoing, and without limiting the rights and
remedies of the Lenders under Section 10, in the event that any Event of Default

request of the Majority Lenders shall) suspend the right of Borrower to Convert

aggregate minimum amount of $500,000 and integral multiples of $100,000 in
excess of such amount, at 100% of the principal amount thereof, plus a premium
equal to, for each Lender, the interest rate in effect on such Lender's portion
of the Tenn Loan on the date notice of prepayment is given multiplied by the

     prepayment of, the Senior Credit Facility, upon any Equity Issuance after
     the Closing Date, the Initial Loan shall be prepaid in an aggregate
     principal amount equal to 50% of the Net Available Proceeds of such Equity

     amount equal to 100% of the Net Available Proceeds of such Debt Issuance.
     Upon the request of the Administrative Agent on behalf of the Majority
     Lenders, Borrower shall apply such Net Available Proceeds to the prepayment
     of Indebtedness outstanding under the Holding Bridge Loan Agreement.

     (the date of such occurrence being the "Change of Control Date"), Borrower
                                             ----------------------

     prescribed by this Agreement and shall, within 20 days after the Change of
     Control Date, make an Offer to Purchase all Initial Notes or Term Notes
     then outstanding, as the case may be, at a purchase price in cash equal to
     10 1% of the aggregate principal amount thereof, plus accrued and unpaid
     interest thereon, if any, to the Purchase Date. Borrowers obligations may
     be satisfied if a third parry makes the Offer to Purchase in the manner, at
     the times and otherwise in compliance with the requirements of this
     Agreement applicable to an Offer to Purchase made by Borrower and purchases
     all Initial Notes or Term Notes validly tendered and not withdrawn under

     portion of the Initial Notes or Term Notes owned by such Lender pursuant to
     the Offer to Purchase, subject to the requirement that any portion of an
     Initial Note or a Term Note tendered must be tendered in an integral

     Purchase, (ii) deposit with the Arranger money sufficient to pay the
     Purchase Price of all Initial Notes or Term Notes or portions thereof so
     accepted and (iii) deliver or cause to be delivered to the Arranger for
     cancellation all Term Notes so accepted together with an Officers'
     Certificate stating the Initial Notes or Term Notes or portions thereof
     accepted for payment by Borrower.  The Arranger shall promptly mail or
     deliver to Lenders whose Initial Notes or Term Notes are so accepted
     payment in an amount equal to the Purchase Price for such Initial Notes or
     Initial Notes or Term Notes, and the Arranger shall promptly authenticate
     and mail or deliver to each Lender a new Initial Notes or Tenn Note or Term
     Notes equal in principal amount to any unpurchased portion of the Initial
     Notes or Term Note surrendered as requested by the Lender.  Any Initial
     Notes or Term Note not accepted for payment shall be promptly mailed or
     delivered by Borrower to the Lender thereof. 

                                     -33-

 
     Borrower shall publicly announce the results of the Offer to Purchase on or

     Offer to Purchase all outstanding Notes up to a maximum principal amount
     (expressed as a multiple of $1,000) of Notes equal to the Note Portion of
     Unutilized Net Cash Proceeds. Such Offer to Purchase shall be made at a
     purchase price in cash equal to 100% of the principal amount thereof, plus
     accrued and unpaid interest thereon, if any, to the Purchase Date;
     provided, however, that the Offer to Purchase may be deferred until there
     --------  -------                                                        
     are aggregate Unutilized Net Cash Proceeds equal to or in excess of $15.0
     million, at which time the entire amount of such Unutilized Net Cash
     Proceeds, and not just the amount in excess of $15.0 million, shall be
     applied as required pursuant to this paragraph.

          In the event that any other Indebtedness of Borrower which ranks pari

     to purchase to be made to repurchase such Other Indebtedness upon the
     consummation of any Asset Sale, Borrower may apply the Unutilized Net Cash
     Proceeds otherwise required to be applied to an Offer to Purchase to offer
     to purchase such Other Indebtedness and to an Offer to Purchase so long as
     the amount of such Unutilized Net Cash Proceeds applied to repurchase the
     Notes is not less than the Note Portion of Unutilized Net Cash Proceeds.
     With respect to any Unutilized Net Cash Proceeds, Borrower shall make the
     Offer to Purchase in respect thereof at the same time as the analogous
     offer to purchase is made under the Senior Subordinated Indenture and
     pursuant to any Other Indebtedness and the Purchase Date in respect thereof
     shall be the same as the purchase date in respect thereof pursuant to the
     Senior Subordinated Indenture and pursuant to any Other Indebtedness.

          For purposes of this Section 2.10(iii), "Note Portion of Unutilized
                                                   --------------------------
     Net Cash Proceeds" means the amount of the Unutilized Net Cash Proceeds

     equal to the product of (x) the Unutilized Net Cash Proceeds and (y) a
     fraction the numerator of which is the principal amount of all Notes
     tendered pursuant to the Offer to Purchase related to such Unutilized Net
     Cash Proceeds (the "Note Amount") and the denominator of which is the sum
     of the Note Amount and the lesser of the aggregate principal face amount or
     accreted value as of the relevant purchase date of all Other Indebtedness
     tendered pursuant to a concurrent offer to purchase such Other Indebtedness
     made at the time of such Offer to Purchase.

          With respect to any Offer to Purchase effected pursuant to this
     Section 2.10(iii), as among the Term Notes, to the extent that the
     principal amount of the Notes tendered pursuant to such Offer to Purchase
     exceeds the Note Portion of Unutilized Net Cash Proceeds with respect
     thereto, such Notes shall be purchased pro rata based on the principal
                                            ---------                      
     amount of such Term Notes tendered by each Lender.

          Each Lender shall be entitled to tender all or any portion of the
     Notes owned by such Lender pursuant to the Offer to Purchase, subject to
     the requirement that any portion of a Note tendered must be tendered in an
     integral multiple of $1,000 principal amount and subject to any proration
     among tendering Lenders as described above.

     incapable of making LIBOR Loans as provided in Section 5.03 and/or (y) as
     provided in Section 12.04(ii), such Lender refuses to consent to certain
     proposed amendments, waivers or modifications with respect to this

     Replacement Lender shall acquire all of the Commitments and outstanding
     Loans of the Replaced Lender and, in connection therewith, shall pay to the
     Replaced Lender, an amount equal to the sum of (A) the principal of, and
     all accrued interest on, all outstanding Loans of the Replaced Lender and
     (B) all accrued, but

     theretofore unpaid, fees owing to the Replaced Lender pursuant to Section
     2.05, and (ii) all obligations of Borrower owing to the Replaced Lender
     (other than those specifically described in clause (i) above in respect of
     which the assignment purchase price has been, or is concurrently being,
     paid, but including any amounts which would be paid to a Lender pursuant to
     Section 5.05 if Borrower were prepaying a LIBOR Loan) shall be paid in full
     to such Replaced Lender concurrently with such replacement. Upon the
     execution of the respective assignment agreement, the payment of amounts

     prepayment pursuant to Section 2.09. In order to request the conversion of

being prepaid) and at maturity.

          If, on any interest payment date, the interest accrued for the period
prior to such interest payment date exceeds the amount that would have accrued
at 14.00%, Borrower may pay all or a portion of the interest payable in excess
of the amount of interest that would be payable on such date at 14.00% by
issuance of Subsequent Initial Notes or Subsequent Term Notes, as the case may
be, in an aggregate principal amount equal to the amount of such interest being
so paid in Subsequent Initial Notes or Subsequent Term Notes (the "PIK Interest

any such payment is not made in full by Administrative Agent, Administrative
Agent shall pay to such Lender, upon demand, interest at the Federal Funds Rate
from the date such amount was required to be paid to such Lender pursuant to the
foregoing clauses until the date Administrative Agent pays such Lender the
amount).

          (d) If the due date of any payment under this Agreement or any Note
would otherwise fall on a day that is not a Business Day, such date shall be
extended to the next succeeding Business Day, and interest shall be payable for
any principal so extended for the period of such extension.

borrowed, Converted, Continued or prepaid and the date of borrowing, Conversion,
Continuation or prepayment (which shall be a Business Day). Administrative Agent
shall promptly notify the Lenders of the contents of each such notice. In the
event that Borrower fails to select the Type of Loan within the time period and
otherwise as provided in this Section 4.05, such Loan (if outstanding as a LIBOR
Loan) will be automatically Converted into a LIBOR Loan or (if outstanding as an
ABR Loan) will remain as, or (if not then outstanding) will be made as, an ABR
Loan.

          4.06.     Non-Receipt of Funds by Administrative Agent.  Unless
                    --------------------------------------------         
Administrative Agent shall have received written notice from a Lender or
Borrower (the "Payor")prior to the date on which the Payor is to make payment to
               -----                                                            
Administrative Agent of (in the case of a Lender) the proceeds of a Loan to be
made by such Lender hereunder or a payment to Administrative Agent for the
account of one or more of the Lenders hereunder (such payment being herein
called the "Required Payment"), which notice shall be effective upon receipt,
            ----------------                                                 
that the Payor does not intend to make the Required Payment to Administrative
Agent, Administrative Agent may assume that the Required Payment has been made
and may, in reliance upon such assumption (but shall not be required to), make
the amount thereof available to the intended recipient(s) on such date; and, if
the Payor has not in fact made the Required Payment to Administrative Agent, the
recipient(s) of such payment shall, on demand, repay to Administrative Agent the
amount so made available together with interest thereon in respect of each day
during the period commencing on the date (the "Advance Date") such amount was so
                                               ------------                     
made available by Administrative Agent until the date Administrative Agent
recovers such amount at a rate per annum equal to the Federal Funds Rate for
                               --- -----                                    
such day and, if such recipient(s) shall fail promptly to make such payment,
Administrative Agent shall be entitled to recover such amount, on demand, from
the Payor, together with interest as aforesaid; provided, however, that if
                                                --------  -------         
neither the recipient(s) nor the Payor shall return the Required Payment to
Administrative Agent within three Business Days of the Advance Date, then,
retroactively to the Advance Date, the Payor and the recipient(s) shall each be
obligated to pay interest on the Required Payment as follows (without double
recovery):

          (i)   if the Required Payment shall represent a payment to be made by
     Borrower to the Lenders, Borrower and the recipient(s) shall each be
     obligated retroactively to the Advance Date to pay interest in respect of
     the Required Payment at the rate set forth in Section 3.02(b) (without
     duplication of the obligation of Borrower under Section 3.02 to pay
     interest on the Required Payment at the rate set forth in Section 3.02(b)),
     it being understood that the return by the recipient(s) of the Required
     Payment to Administrative Agent shall not limit such obligation of Borrower
     under Section 3.02 to pay interest at the rate set forth in Section 3.02(b)
     in respect of the Required Payment and

          (ii)  if the Required Payment shall represent proceeds of a Loan to be
     made by the Lenders to Borrower, the Payor and Borrower shall each be
     obligated retroactively to the Advance Date to pay interest in respect of
     the Required Payment pursuant to Section 3.02, it being understood that the
     return by Borrower 

                                     -37-

 
     of the Required Payment to Administrative Agent shall not limit any claim
     Borrower may have against the Payor in respect of such Required Payment.

          4.07.     Right of Setoff, Sharing of Payments, Etc.  (a) If any Event
                    -----------------------------------------                   
of Default shall have occurred and be continuing, each Obligor agrees that, in
addition to (and without limitation of) any right of setoff, banker's lien or
counterclaim a Lender may otherwise have, each Lender shall be entitled, at its
option (to the fullest extent permitted by law), to set off and apply any
deposit (general or special, time or demand, provisional or final), or other
indebtedness, held by it for the credit or account of such Obligor at any of its
offices, in Dollars or in any other currency, against any principal of or
interest on any of such Lender's Loans or any other amount payable to such
Lender hereunder that is not paid when due (regardless of whether such deposit
or other indebtedness is then due to such Obligor), in which case it shall
promptly notify such Obligor and Administrative Agent thereof; provided,
                                                               -------- 
however, that such Lenders failure to give such notice shall not affect the
- - -------                                                                    
validity thereof.

          (b) Each of the Lenders agrees that, if it should receive (other than
pursuant to Section 5) any amount hereunder (whether by voluntary payment, by
realization upon security, by the exercise of the right of setoff or banker's
lien, by counterclaim or cross action, by the enforcement of any right under the
Credit Documents, or otherwise) which is applicable to the payment of the
principal of, or interest on, the Loans or fees, of a sum which with respect to
the related sum or sums received by other Lenders is in a greater proportion
than the total of such amounts then owed and due to such Lender bears to the
total of such amounts then owed and due to all of the Lenders immediately prior
to such receipt, then such Lender receiving such excess payment shall purchase
for cash without recourse or warranty from the other Lenders an interest in the
Obligations of the respective Obligor to such Lenders in such amount as shall
result in a proportional participation by all of the Lenders in such amount;
provided, however, that if all or any portion of such excess amount is
- - --------  -------                                                     
thereafter recovered from such Lender, such purchase shall be rescinded and the
purchase price restored to the extent of such recovery, but without interest.
Borrower consents to the foregoing arrangements.

          (c) Borrower agrees that any Lender so purchasing such a participation
may exercise all rights of setoff, banker's lien, counterclaim or similar rights
with respect to such participation as fully as if such Lender were a direct
holder of Loans or other amounts (as the case may be) owing to such Lender in
the amount of such participation.

          (d) Nothing contained herein shall require any Lender to exercise any
such right or shall affect the right of any Lender to exercise, and retain the
benefits of exercising, any such right with respect to any other Indebtedness or
obligation of any Obligor. If, under any applicable bankruptcy, insolvency or
other similar law, any Lender receives a secured claim in lieu of a setoff to
which this Section 4.07 applies, such Lender shall, to the extent practicable,
exercise its rights in respect of such secured claim in a manner consistent with
the rights of the Lenders entitled under this Section 4.07 to share in the
benefits of any recovery on such secured claim.

          Section 5.   Yield Protection, Etc.
                       --------------------- 

          5.01.     Additional Costs.  (a) If the adoption of, or any change in,
                    ----------------                                            
any Requirement of Law or in the interpretation or application thereof or
compliance by any Lender with any request or directive (whether or not having
the force of law) from any central bank or other Governmental Authority or the
NAIC made subsequent to the date hereof:

          (i)  shall subject any Lender to any tax of any kind whatsoever with
     respect to this Agreement, any Note or any LIBOR Loan made by it or change
     the basis of taxation of payments to such Lender in respect thereof by any
     Governmental Authority (except for taxes covered by Section 5.06 and
     changes in the rate of tax on the overall net income of such Lender or its
     Applicable Lending Office, or any affiliate thereof or franchise tax by any
     Governmental Authority);

          (ii) shall impose, modify or hold applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by,
     deposits or other liabilities in or for the account of, advances, loans 

                                     -38-

 
     or other extensions of credit by, or any other acquisition of funds by, any
     office of such Lender which is not otherwise included in the determination
     of the LIBOR Rate hereunder; or

          (iii)  shall impose on such Lender any other condition (excluding
     taxes);

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining LIBOR Loans or issuing or participating in Letters of
Credit or to reduce any amount receivable hereunder in respect thereof then, in
any such case, Borrower shall promptly pay such Lender, upon its demand, any
additional amounts necessary to compensate such Lender for such increased cost
or reduced amount receivable. If any Lender becomes entitled to claim any
additional amounts pursuant to this subsection, it shall promptly notify
Borrower, through Administrative Agent, of the event by reason of which it has
become so entitled.  A certificate as to any additional amounts setting forth
the calculation of such additional amounts pursuant to this Section 5.01
submitted by such Lender, through Administrative Agent, to Borrower shall be
conclusive in the absence of clearly demonstrable error.

Without limiting the survival of any other covenant hereunder, this Section 5.01
shall survive the termination of this Agreement and the payment of the Notes and
all other amounts payable hereunder.

          (b) In the event that any Lender shall have determined that the
adoption of any law, rule, regulation or guideline regarding capital adequacy
(or any change therein or in the interpretation or application thereof) or
compliance by any Lender or any corporation controlling such Lender with any
request or directive regarding capital adequacy (whether or not having the force
of law) from any central bank or Governmental Authority or the NAIC, in each
case, made subsequent to the date hereof including, without limitation, the
issuance of any final rule, regulation or guideline, does or shall have the
effect of reducing the rate of return on such Lenders or such corporation's
capital as a consequence of its obligations hereunder to a level below that
which such Lender or such corporation could have achieved but for such adoption,
change or compliance (taking into consideration such Lender's or such
corporation's policies with respect to capital adequacy) by an amount deemed by
such Lender to be material, then from time to time, after submission by such
Lender to Borrower (with a copy to Administrative Agent) of a written request
therefor, Borrower shall promptly pay to such Lender such additional amount or
amounts as will compensate such Lender for such reduction.

          5.02.     Limitation on Types of Loans.  Anything herein to the
                    ----------------------------                         
contrary notwithstanding, if, on or prior to the determination of any LIBOR Base
Rate for any Interest Period:

          (i)  Administrative Agent determines, which determination shall be
     conclusive, absent manifest error, that quotations of interest rates for
     the relevant deposits referred to in the definition of "LIBOR Base Rate" in
     Section 1.0 1 are not being provided in the relevant amounts or for the
     relevant maturities for purposes of determining rates of interest for LIBOR
     Loans as provided herein; or

          (ii) the Majority Lenders determine, which determination shall be
     conclusive, that the relevant rates of interest referred to in the
     definition of "LIBOR Base Rate" in Section 1.01 upon the basis of which the
     rate of interest for LIBOR Loans for such Interest Period is to be
     determined are not likely adequate to cover the cost to the applicable
     Lenders of making or maintaining LIBOR Loans for such Interest Period,

then Administrative Agent shall give Borrower and each Lender prompt notice
thereof, and so long as such condition remains in effect, the affected Lenders
shall be under no obligation to make additional LIBOR Loans, to Continue LIBOR
Loans or to Convert ABR Loans into LIBOR Loans and Borrower shall, on the last
day(s) of the then current Interest Period(s) for the outstanding LE30R Loans,
either prepay such Loans or Convert such Loans into ABR Loans in accordance with
Section 2.09.

          5.03.     Breakage and Illegality.  Notwithstanding any other
                    -----------------------                            
provision of this Agreement, in the event that any change in any Requirement of
Law or in the interpretation or application thereof shall make it unlawful for
any Lender or its Applicable Lending Office to honor its obligation to make or
maintain LIBOR Loans hereunder 

                                     -39-

 
(and, in the sole opinion of such Lender, the designation of a different
Applicable Lending Office would either not avoid such unlawfulness or would be
disadvantageous to such Lender), then such Lender shall promptly notify Borrower
thereof (with a copy to Administrative Agent) and such Lender's obligation to
make or Continue, or to Convert Loans of any other Type into, LIBOR Loans shall
be suspended until such time as such Lender may again make and maintain LIBOR
Loans (in which case the provisions of Section 5.04 shall be applicable).

          5.04.     Treatment of Affected Loans.  If the obligation of any
                    ---------------------------                           
Lender to make LIBOR Loans or to Continue, or to Convert ABR Loans into, LIBOR
Loans shall be suspended pursuant to Section 5.03, such Lender's LIBOR Loans
shall be automatically Converted into ABR Loans on the last day(s) of the then
current Interest Period(s) for such LIBOR Loans (or on such earlier date as such
Lender may specify to Borrower with a copy to Administrative Agent as is
required by law) and, unless and until such Lender gives notice as provided
below that the circumstances specified in Section 5.03 which gave rise to such
Conversion no longer exist:

          (i)  to the extent that such Lender's LIBOR Loans have been so
     Converted, all payments and prepayments of principal which would otherwise
     be applied to such Lender's LIBOR Loans shall be applied instead to its ABR
     Loans; and

          (ii) all Loans which would otherwise be made or Continued by such
     Lender as LIBOR Loans shall be made or Continued instead as ABR Loans and
     all ABR Loans of such Lender which would otherwise be Converted into LIBOR
     Loans shall remain as ABR Loans.

If such Lender gives notice to Borrower with a copy to Administrative Agent that
the circumstances specified in Section 5.03 which gave rise to the Conversion of
such Lender's LIBOR Loans pursuant to this Section 5.04 no longer exist (which
such Lender agrees to do promptly upon such circumstances ceasing to exist) at a
time when LIBOR Loans are outstanding, such Lender's ABR Loans shall be
automatically Converted, on the first day(s) of the next succeeding Interest
Period(s) for such outstanding LIBOR Loans, to the extent necessary so that,
after giving effect thereto, all Loans held by the Lenders holding LIBOR Loans
and by such Lender are held pro rata (as to principal amounts, Types and
                            --- ----                                    
Interest Periods) in accordance with their respective Commitments.

          5.05.     Compensation.  (a) Borrower agrees to indemnify each Lender
                    ------------                                               
and to hold each Lender harmless from any loss or expense which such Lender may
sustain or incur as a consequence of (1) default by Borrower in payment when due
of the principal amount of or interest on any LIBOR Loan, (2) default by
Borrower in making a borrowing of, Conversion into or Continuation of LIBOR
Loans after Borrower has given a notice requesting the same in accordance with
the provisions of this Agreement, (3) default by Borrower in making any
prepayment after Borrower has given a notice thereof in accordance with the
provisions of the Agreement, or (4) the making of a payment or a prepayment of
LIBOR Loans on a day which is not the last day of an Interest Period with
respect thereto, including in each case, any such loss (including loss of
margin) or expense arising from the reemployment of funds obtained by it or from
fees payable to terminate the deposits from which such funds were obtained.

          (b)  For the purpose of calculation of all amounts payable to a Lender
under this Section 5.05 each Lender shall be deemed to have actually funded its
relevant LIBOR Loan through the purchase of a deposit bearing interest at the
LIBOR Rate in an amount equal to the amount of the LIBOR Loan and having a
maturity comparable to the relevant Interest Period; provided, however, that
                                                     --------  -------      
each Lender may fund each of its LIBOR Loans in any manner it sees fit, and the
foregoing assumption shall be utilized only for the calculation of amounts
payable under this subsection. Any Lender requesting compensation pursuant to
this Section 5.05 will furnish to Administrative Agent and Borrower a
certificate setting forth the basis and amount of such request and such
certificate, absent manifest effort, shall be conclusive. Without limiting the
survival of any other covenant hereunder, this covenant shall survive the
termination of this Agreement and the payment of the Notes and all other amounts
payable hereunder.

          5.06.     Net Payments.  (a) All payments made by Borrower or any
                    ------------                                           
Guarantor hereunder or under any Note or any Guarantee will be made without
setoff, counterclaim or other defense. Except as provided in Section 5.06(b),
all such payments will be made free and clear of, and without deduction or
withholding for, any present or future taxes, levies, imposts, duties, fees,
assessments or other charges of whatever nature now or hereafter imposed 

                                     -40-

 
by any Governmental Authority or by any political subdivision or taxing
authority thereof or therein with respect to such payments (but excluding,
except as provided in the second succeeding sentence, any tax imposed on or
measured by the net income or net profits of a Lender pursuant to the laws of
the jurisdiction in which it is organized or the jurisdiction in which the
principal office or Applicable Lending Office of such Lender is located or any
jurisdiction in which such Lender conducts business or any subdivision thereof
or therein) and all interest, penalties or similar liabilities with respect
thereto (all such non-excluded taxes, levies, imposts, duties, fees, assessments
or other charges being referred to collectively as "Covered Taxes"). If any
                                                    -------------          
Covered Taxes are so levied or imposed, Borrower and each Guarantor, as the case
may be, agrees to pay the full amount of such Covered Taxes, and such additional
amounts as may be necessary so that every payment of all amounts due under this
Agreement, the Guarantees or under any Note, after withholding or deduction for
or on account of any Covered Taxes, will not be less than the amount provided
for herein or in such Note.  If any amounts are payable in respect of Covered
Taxes pursuant to the preceding sentence, Borrower and each Guarantor agrees on
a joint and several basis to reimburse each Lender, upon the written request of
such Lender, (i) for taxes imposed on or measured by the net income or net
profits of such Lender pursuant to the laws of the jurisdiction in which such
Lender is organized or in which the principal office or Applicable Lending
Office of such Lender is located or under the laws of any political subdivision
or taxing authority of any such jurisdiction by reason of the making of payments
in respect of Covered Taxes pursuant to this Section (including pursuant to this
sentence) and (ii) for any withholding of taxes as such Lender shall determine
are payable by, or withheld from, such Lender in respect of amounts paid in
respect of Covered Taxes to or on behalf of such Lender pursuant to the
preceding sentence and in respect of any amounts paid to or on behalf of such
Lender pursuant to this sentence. Borrower and each Guarantor, as the case may
be, will furnish to Administrative Agent within 45 days after the date the
payment of any Covered Taxes is due pursuant to applicable law certified copies
of tax receipts evidencing such payment by Borrower or any Guarantor.  Borrower
and the Guarantors agree to jointly and severally indemnify and hold harmless
each Lender, and reimburse such Lender upon its written request, for the amount
of any Covered Taxes so levied or imposed and paid by such Lender and any
liability (including penalties, additions to tax, interest and expenses) arising
therefrom or with respect thereto.

          (b) Each Lender that is not a United States person (as such term is
defined in Section 7701(a)(30) of the Code) (a "Non-U.S. Lender") agrees to
                                                ---------------            
deliver to Borrower and Administrative Agent on or prior to the Closing Date or,
in the case of a Lender that is an assignee or transferee of an interest under
this Agreement pursuant to Section 12.06 (unless the respective Lender was
already a Lender hereunder immediately prior to such assignment or transfer), on
the date of such assignment or transfer to such Lender, (i) two accurate and
complete original signed copies of Internal Revenue Service Form 4224 or 100 1
(or successor forms) certifying to such Lenders entitlement to a complete
exemption from, or reduction in rate of, United States withholding tax with
respect to payments to be made under this Agreement and under any Note (or, with
respect to any assignee Lender, at least as extensive as the assigning Lender),
or (ii) if the Lender is not a "bank" within the meaning of Section 88
I(c)(3)(A) of the Code and cannot deliver either Internal Revenue Service Form
1001 or 4224 pursuant to clause (i) above, (x) a certificate substantially in
the form of Exhibit K (any such certificate, a "Section 5.06 Certificate") and
                                                ------------------------      
(y) two accurate and complete original signed copies of Internal Revenue Service
Form W-8 (or successor form) certifying to such Lender's entitlement to a
complete exemption from, or reduction in rate of, United States withholding tax
with respect to payments to be made under this Agreement and under any Note (or,
with respect to any assignee Lender, at least as extensive as the assigning
Lender). In addition, each Lender agrees that from time to time after the
Closing Date, when a lapse in time or change in circumstances renders the
previous certification obsolete or inaccurate in any material respect, it will
deliver to Borrower and Administrative Agent two new accurate and complete
original signed copies of Internal Revenue Service Form 4224 or 100 1, or Form
W-8 and a Section 5.06 Certificate, as the case may be, and such other forms as
may be required in order to confirm or establish the entitlement of such Lender
to a continued exemption from or reduction in United States withholding tax with
respect to payments under this Agreement and any Note, or it shall immediately
notify Borrower and Administrative Agent of its inability to deliver any such
Form or Certificate, in which case such Lender shall not be required to deliver
any such form or certificate pursuant to this Section 5.06(b).  Notwithstanding
the foregoing, no Lender shall be required to deliver any such form or
certificate if a change in treaty, law or regulation has occurred prior to the
date on which such delivery would otherwise be required that renders any such
form or certificate inapplicable or would prevent the Lender from duly
completing and delivering any such form or certificate with respect to it and
such Lender so advises Borrower. Borrower shall not be required to indemnify any
Non-U.S. Lender, or to pay any additional amounts to any Non-U.S. 

                                     -41-

 
Lender, in respect of U.S. Federal withholding tax pursuant to paragraph (a)
above to the extent that (i) the obligation to withhold amounts with respect to
U.S. Federal withholding tax existed on the date such Non-U.S. Lender became a
party to this Agreement; provided, however, that this clause (i) shall not apply
                         --------  -------
to the extent that (x) the indemnity payments or additional amounts any Lender
would be entitled to receive (without regard to this clause (i)) do not exceed
the indemnity payments or additional amounts that the Person making the
assignment or transfer to such Lender would have been entitled to receive in the
absence of such assignment or transfer, or (y) such assignment or transfer had
been requested by Borrower, or (ii) the obligation to pay such additional
amounts would not have arisen but for a failure by such Non-U.S. Lender to
comply with the provisions of this Section 5.06(b). Notwithstanding anything to
the contrary contained in the preceding sentence or elsewhere in this Section
5.06 and except as set forth in Section 12.06(b), Borrower agrees to pay
additional amounts and to indemnify each Lender in the manner set forth in
Section 5.06(a) (without regard to the identity of the jurisdiction requiring
the deduction or withholding) in respect of any amounts deducted or withheld by
it as described in the immediately preceding sentence as a result of any changes
after the Closing Date in any applicable law, treaty, governmental rule,
regulation, guideline or order, or in the interpretation thereof, relating to
the deducting or withholding of income or similar Covered Taxes.

          (c)  In addition, Borrower agrees to pay any present or future stamp
or documentary taxes or any other excise or property taxes, charges or similar
levies which arise from any payment made hereunder or under the Note or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement or the Notes (hereinafter referred to as "Other Taxes").

                       --------- 

          6.01.     The Guarantee.  The Guarantors hereby jointly and severally
                    -------------                                              
guarantee as a primary obligor and not as a surety to each Lender and Agent and
their respective successors and assigns the prompt payment in full when due
(whether at stated maturity, by acceleration or otherwise) of the principal of
and interest (including any interest that would accrue but for the provisions of
the Bankruptcy Code after any bankruptcy or insolvency petition under the
Bankruptcy Code) on the Loans made by the Lenders to, and the Notes held by each
Lender of, Borrower and all other Obligations from time to time owing to the
Lenders or Agents by Borrower under this Agreement and under the Notes and by
any Obligor under any of the other Credit Documents, in each case strictly in
accordance with the terms thereof (such obligations being herein collectively
called the "Guaranteed Obligations").  The Guarantors hereby jointly and
            ----------------------                                      
severally agree that if Borrower shall fail to pay in full when due (whether at
stated maturity, by acceleration or otherwise) any of the Guaranteed
Obligations, the Guarantors will promptly pay the same, without any demand or
notice whatsoever, and that in the case of any extension of time of payment or
renewal of any of the Guaranteed Obligations, the same will be promptly paid in
full when due (whether at extended maturity, by acceleration or otherwise) in
accordance with the terms of such extension or renewal.

          6.02.     Obligations Unconditional.  The obligations of the
                    -------------------------                         
Guarantors under Section 6.01 are absolute, irrevocable and unconditional, joint
and several, irrespective of the value, genuineness, validity, regularity or
enforceability of the obligations of Borrower under this Agreement, the Notes or
any other agreement or instrument referred to herein or therein, or any
substitution, release or exchange of any other guarantee of or security for any
of the Guaranteed Obligations, and, to the fullest extent permitted by
applicable law, irrespective of any other circumstance whatsoever that might
otherwise constitute a legal or equitable discharge or defense of a surety or
Guarantor (except for payment in full). Without limiting the generality of the
foregoing, it is agreed that the occurrence of any one or more of the following
shall not alter or impair the liability of the Guarantors hereunder which shall
remain absolute, irrevocable and unconditional under any and all circumstances
as described above:

          (i)  at any time or from time to time, without notice to the
     Guarantors, the time for any performance of or compliance with any of the
     Guaranteed Obligations shall be extended, or such performance or compliance
     shall be waived;

          (ii) any of the acts mentioned in any of the provisions of this
     Agreement or the Notes or any other agreement or instrument referred to
     herein or therein shall be done or omitted;

                                     -42-

 
          (iii)  the maturity of any of the Guaranteed Obligations shall be
     accelerated, or any of the Guaranteed Obligations shall be amended in any
     respect, or any right under this Agreement, the Notes or any other Credit
     Document or any other agreement or instrument referred to herein or therein
     shall be amended or waived in any respect or any other guarantee of any of
     the Guaranteed Obligations or any security therefor shall be released or
     exchanged in whole or in part or otherwise dealt with;

          (iv)   the release of any other Guarantor.

          The Guarantors hereby expressly waive diligence, presentment, demand
of payment, protest and all notices whatsoever, and any requirement that any
Agent or any Lender exhaust any right, power or remedy or proceed against
Borrower under this Agreement or the Notes or any other agreement or instrument
referred to herein or therein, or against any other Person under any other
guarantee of, or security for, any of the Guaranteed Obligations.  The
Guarantors waive any and all notice of the creation, renewal, extension, waiver,
termination or accrual of any of the Guaranteed Obligations and notice of or
proof of reliance by any Lender or any Agent upon this guarantee or acceptance
of this guarantee, and the Guaranteed Obligations, and any of them, shall
conclusively be deemed to have been created, contracted or incurred in reliance
upon this guarantee, and all dealings between Borrower and the Lenders and
Agents shall likewise be conclusively presumed to have been had or consummated
in reliance upon this guarantee. This guarantee shall be construed as a
continuing, absolute, irrevocable and unconditional guarantee of payment without
regard to any right of offset with respect to the Guaranteed Obligations at any
time or from time to time held by the Lenders and Agents, and the obligations
and liabilities of the Guarantors hereunder shall not be conditioned or
contingent upon the pursuit by the Lenders or Agents or any other Person at any
time of any right or remedy against Borrower or against any other Person which
may be or become liable in respect of all or any part of the Guaranteed
Obligations or against any collateral security or guarantee therefor or right of
offset with respect thereto. This guarantee shall remain in full force and
effect and be binding in accordance with and to the extent of its terms upon the
Guarantors and the successors and assigns thereof, and shall inure to the
benefit of the Lenders, and their respective successors and assigns,
notwithstanding that from time to time during the term of this Agreement there
may be no Guaranteed Obligations outstanding.

          6.03.     Reinstatement.  The obligations of the Guarantors under this
                    -------------                                               
Section 6 shall be automatically reinstated if and to the extent that for any
reason any payment by or on behalf of Borrower in respect of the Guaranteed
Obligations is rescinded or must be otherwise restored by any holder of any of
the Guaranteed Obligations, whether as a result of any proceedings in bankruptcy
or reorganization or otherwise.  The Guarantors jointly and severally agree that
they will indemnify each Agent and each Lender on demand for all reasonable
costs and expenses (including reasonable fees of counsel) incurred by such Agent
or such Lender in connection with such rescission or restoration, including any
such costs and expenses incurred in defending against any claim alleging that
such payment constituted a preference, fraudulent transfer or similar payment
under any bankruptcy, insolvency or similar law, other than any costs or
expenses resulting from the gross negligence or bad faith of such Creditor.

          6.04.     Subrogation; Subordination.  Each Guarantor hereby agrees
                    --------------------------                               
that until the indefeasible payment and satisfaction in full in cash of all
Guaranteed Obligations and the expiration and termination of the Commitments of
the Lenders under this Agreement it shall not exercise any right or remedy
arising by reason of any performance by it of its guarantee in Section 6.01,
whether by subrogation or otherwise, against Borrower or any other Guarantor of
any of the Guaranteed Obligations or any security for any of the Guaranteed
Obligations.  The payment of any amounts due with respect to any indebtedness of
Borrower or any other Guarantor now or hereafter owing to any Guarantor by
reason of any payment by such Guarantor under the Guarantee in this Section 6 is
hereby subordinated to the prior indefeasible payment in full in cash of the
Guaranteed Obligations.  Each Guarantor agrees that it will not demand, sue for
or otherwise attempt to collect any such indebtedness of Borrower to such
Guarantor until the Obligations shall have been indefeasibly paid in full in
cash.  If, notwithstanding the foregoing sentence, any Guarantor shall prior to
the indefeasible payment in full in cash of the Guaranteed Obligations collect,
enforce or receive any amounts in respect of such indebtedness, such amounts
shall be collected, enforced and received by such Guarantor as trustee for
Agents and the Lenders and be paid over to Administrative Agent on account of
the Guaranteed Obligations without affecting in any manner the liability of such
Guarantor under the other provisions of the guaranty contained herein.

                                     -43-

 
          6.05.     Remedies.  The Guarantors jointly and severally agree that,
                    --------                                                   
as between the Guarantors and the Lenders, the obligations of Borrower under
this Agreement and the Notes may be declared to be forthwith due and payable as
provided in Section 10 (and shall be deemed to have become automatically due and
payable in the circumstances provided in said Section 10) for purposes of
Section 6.01 notwithstanding any stay, injunction or other prohibition
preventing such declaration (or such obligations from becoming automatically due
and payable) as against Borrower and that, in the event of such declaration (or
such obligations being deemed to have become automatically due and payable),
such obligations (whether or not due and payable by Borrower) shall forthwith
become due and payable by the Guarantors for purposes of Section 6.01.

          6.06.     Instrument for the Payment of Money.  Each Guarantor hereby
                    -----------------------------------                        
acknowledges that the guarantee in this Section 6 constitutes an instrument for
the payment of money, and consents and agrees that any Lender or Agent, at its
sole option, in the event of a dispute by such Guarantor in the payment of any
moneys due hereunder, shall have the right to bring motion-action under New York
CPLR Section 3213.

          6.07.     Continuing Guarantee.  The guarantee in this Section 6 is a
                    --------------------                                       
continuing guarantee, and shall apply to all Guaranteed Obligations whenever
arising.

          6.08.     General Limitation on Guarantee Obligations.  In any action
                    -------------------------------------------                
or proceeding involving any state corporate law, or any state, Federal or
foreign bankruptcy, insolvency, reorganization or other law affecting the rights
of creditors generally, if the obligations of any Guarantor under Section 6.01
would otherwise be held or determined to be void, voidable, invalid or
unenforceable, or subordinated to the claims of any other creditors, on account
of the amount of its liability under Section 6.01, then, notwithstanding any
other provision to the contrary, the amount of such liability shall, without any
further action by such Guarantor, any Lender, any Agent or any other Person, be
automatically limited and reduced to the highest amount that is valid and
enforceable and not subordinated to the claims of other creditors as determined
in such action or proceeding; provided, that, without limiting the generality of
                              --------                                          
the foregoing, in any such action or proceeding in which KRS 371.065governs, (i)
the maximum aggregate liability of any Guarantor under Section 6.01 shall be
deemed to be $500,000,000 and (ii) the guarantee shall terminate on September
30, 2006; provide, further, that nothing herein shall be construed to imply
          ------- 
that KRS 371.065 governs.

          8.11.     Environmental Matters.  Except as disclosed in Schedule 8.11
                    ---------------------                          -------------
and except as would not, individually or in the aggregate, reasonably be

          8.12.     Environmental Investigations.  All material environmental
                    ----------------------------                             
investigations, studies, audits or assessments which have been conducted and
which are in the possession, custody or control of any Company relating (i) to
the current or prior business, operations, facilities or Property of any Company
or any Unrestricted Subsidiary or any of their respective predecessors in
interest or (ii) to any facility, Property or other asset now or previously
owned, operated, leased or used by any Company or any Unrestricted Subsidiary or
any of their respective predecessors in interest have been made available to the
Agents and the Lenders.

          8.13.     Use of Proceeds.  No Company is engaged principally, or as
                    ---------------                                           
one of its important activities, in the business of extending credit for the
purpose, whether immediate, incidental or ultimate, of buying or carrying Margin
Stock and no part of the proceeds of any extension of credit hereunder will be
used directly or indirectly and whether immediately, incidentally or ultimately
to purchase or carry any Margin Stock or to extend credit to others for such
purpose or to refund Indebtedness originally incurred for such purpose.
Following application of the proceeds of each extension of credit hereunder, not
more than 25 percent of the value of the assets (either of Borrower only or of
Borrower and the Subsidiaries on a consolidated basis) will be Margin Stock.
Borrower will use the proceeds of all Initial Loans to finance the Transactions,
pay fees and expenses related thereto, and for general corporate purposes.

          8.14.     Subsidiaries.  As of the Closing Date (after giving effect
                    ------------                                              
to the Transactions), Borrower does not have any Subsidiaries or interests in
partnerships, joint ventures or business trusts other than the entities set
forth on Schedule 8.14(a). Schedule 8.14(b) depicts the organizational structure
         ----------------------------------                                     
of the Obligors as of the Closing Date. Borrower owns, as of the Closing Date,
the percentage of the issued and outstanding Equity Interests or other evidences
of the ownership of each of the Subsidiaries, partnerships or joint ventures
listed on Schedule 8.14 as set forth on such Schedule.  o such Subsidiary,
          -------------                                                   
partnership or joint venture has issued any securities convertible into shares
of its Equity Interests (or other evidence of ownership) or any Equity Rights to
acquire such shares or securities convertible into such shares (or other
evidence of ownership), and the outstanding stock and securities (or other
evidence of ownership) of such Subsidiaries, partnerships or joint ventures are
owned by Borrower and the Subsidiaries free and clear of all Liens and Equity
Rights of others of any kind whatsoever, except for Liens pursuant to the
Security Documents. Any Unrestricted Subsidiary created or acquired after the
Closing Date will be created or acquired in accordance with the terms hereof.

          8.15.     [Reserved].

          8.16.     [Reserved].

          8.17.     Licenses and Permits; Compliance with Laws.  The Companies
                    ------------------------------------------                
hold all governmental permits, licenses, authorizations, consents and approvals
(none of which has been modified or rescinded and all of which are in full force
and effect) (collectively, the "Permits") necessary for the Companies to own,
lease, and operate their respective Properties and to carry on their respective
businesses as now being conducted, except for Permits the failure of which to
obtain could not reasonably be expected to have a Material Adverse Effect.

          The businesses of the Companies are not being conducted in violation
of any applicable Requirement of Law, Permit, concession, grant or other
authorization of any Governmental Authority, except for violations that could
not reasonably be expected to have a Material Adverse Effect.

          There does not exist any judgment, order or injunction prohibiting or
imposing material adverse conditions upon the Transactions, or the performance
by any Obligor of its obligations under the Credit Documents and all applicable
Requirements of Law.

          8.18.     True and Complete Disclosure.  The information, reports,
                    ----------------------------                            
financial statements, exhibits and schedules furnished in writing by or on
behalf of any Obligor to any Creditor (other than the projections referred to in
the following sentence and other than any reserve studies prepared by third
parties) in connection with the negotiation, preparation or delivery of this
Agreement and the other Credit Documents or included herein or therein or
delivered pursuant hereto or thereto or pursuant to any information memorandum
distributed in connection with the syndication of the Commitments and Loans,
including all filings made with the Commission by any Company, 

                                     -53-

 
whether prior to or after the date of this Agreement, when taken as a whole, do
not, as of the date such information was furnished, contain any untrue statement
of material fact or omit to state a material fact necessary in order to make the
statements herein or therein, in light of the circumstances under which they
were made, not materially misleading. The projections and pro forma financial
information furnished at any time by any Obligor to any Creditor pursuant to
this Agreement have been prepared in good faith based on assumptions believed by
Borrower to be reasonable at the time made, it being recognized by the Lenders
that such financial information as it relates to future events is not to be
viewed as fact and that actual results during the period or periods covered by
such financial information may differ from the projected results set forth
therein by a material amount and no Obligor, however, makes any representation
as to the ability of any Company to achieve the results set forth in any such
projections. Borrower understands that all such statements, representations and
warranties shall be deemed to have been relied upon by the Lenders as a material
inducement to make each extension of credit hereunder. As of the Closing Date,
there is no fact known to any Obligor (other than general economic conditions,
which conditions are commonly known and affect businesses generally) that could
reasonably be expected to have a Material Adverse Effect that has not been
expressly disclosed herein, in the other Credit Documents or in any other
documents, certificates and statements furnished to Administrative Agent and the
Lenders for use in connection with the transactions contemplated hereby and by
the other Credit Documents.

          8.19.     Solvency; Etc.  As of the Closing Date immediately prior to
                    -------------                                              
and immediately following the consummation of the Transactions and the
extensions of credit to occur on such date each Obligor is and will be Solvent
(after giving effect to Section 6.08).  Borrower believes that no reasonably
anticipated final judgment in a pending Proceeding or, to its knowledge, any
threatened Proceeding for money damages will be rendered at a time when, or in
an amount such that, any Company will be unable to satisfy such judgments
promptly in accordance with their terms (taking into account the maximum
reasonable amount thereof and the earliest reasonable time at which such
judgments might be rendered).  The cash available to each Company, after taking
into account all other anticipated uses of cash (including the payment of all
such Company's Indebtedness) is anticipated to be sufficient to pay any such
judgments promptly in accordance with their terms.  No Company is contemplating
either the filing of a petition by it under any state or federal bankruptcy or
insolvency laws or the liquidating of all or a substantial portion of its
property, and Borrower has no knowledge of any Person contemplating the filing
of any such petition against any Company.

          8.20.     Contracts.  No Company is in default under any material
                    ---------                                              
contract or agreement to which it is a party or by which it is bound, nor, to
Borrower's knowledge, does any condition exist that, with notice or lapse of
time or both, would constitute such default, excluding in any case such defaults
that could not reasonably be expected to have a Material Adverse Effect.
Schedule 8.20 accurately and completely lists (x) all agreements, if any, among
- - -------------                                                                  
the stockholders (or any of their Affiliates other than any Company) of Borrower
on the one hand and any Company on the other in effect on the date hereof and
all (y) material agreements which are in effect on the date hereof in connection
with the conduct of the business of the Companies.

          8.21.     Labor Matters.  Except as set forth in Schedule 8.21, there
                    -------------                          -------------       
are no strikes or other labor disputes against any Company pending or, to the
knowledge of Borrower, threatened which could reasonably be expected to have a
Material Adverse Effect. Hours worked by and payments made to employees of the
Companies have not been in violation of the Fair Labor Standards Act or any
other applicable Requirements of Law dealing with such matters that
(individually or in the aggregate) could reasonably be expected to have a
Material Adverse Effect. To the knowledge of Borrower, all payments due from any
Company on account of employee health and welfare insurance that (individually
or in the aggregate) could reasonably be expected to have a Material Adverse
Effect if not paid have been paid or accrued as a liability on the books of the
relevant Company.

          8.22.     Year 2000.  Each Company has reviewed their operations with
                    ---------                                                  
a view to assessing whether their business or operations will, in the receipt,
transmissions, processing, manipulation, storage, retrieval, retransmission or
other utilization of data, be vulnerable to any significant risk that computer
hardware, software or any equipment containing embedded microchips used in their
business or operations will not in the case of dates or time periods occurring
after December 31, 1999 function at least as effectively as in the case of dates
or time periods occurring prior to January 1, 2000.  No Company has reason to
believe that the risks associated with the Year 2000 issue could reasonably be
expected to have a Material Adverse Effect.

                                     -54-

 
          Section 9.  Covenants.  Each Obligor, for itself and on behalf of its
                      ---------                                                
Subsidiaries and its Unrestricted Subsidiaries, covenants and agrees with the
Creditors that, so long as any Commitment or Loan is outstanding and until
payment in full of all amounts payable by Borrower hereunder:

          9.01.  Financial Statements, Etc.  The Companies shall deliver to

     Borrower and its Consolidated Subsidiaries as at the end of such period,

     its Consolidated Subsidiaries in accordance with GAAP, consistently
     applied, as at the end of, and for, such period (subject to normal year-end

     qualification or exception, thereon of independent certified public
     accountants of recognized national standing reasonably acceptable to the
     Lenders, which opinion shall state that said consolidated and consolidating
     financial statements fairly present the consolidated and consolidating
     financial condition, results of operations and cash flows of Borrower and
     its Consolidated Subsidiaries as at the end of, and for, such fiscal year
     in accordance with GAAP, consistently applied and a certificate of such
     accountants stating that, in making the examination necessary for their
     opinion, they obtained no knowledge of any Default; Borrower shall supply
     such additional information and detail as to any item or items contained on
     any such statement that Lenders may reasonably require; all such
     information will be prepared in accordance with GAAP consistently applied;

commingle any money or other assets of Borrower or any of the Subsidiaries with
any money or other assets of any Unrestricted Subsidiary; or (d) take any
action, or conduct its affairs in a manner, which could be expected to result in
the separate corporate existence of each of Borrower, each of the Subsidiaries
and each of its Unrestricted Subsidiaries from being ignored or the assets and
liabilities of Borrower or any of the Unrestricted Subsidiaries being
substantively consolidated with those of the Borrower or any other Company in
any Insolvency Proceeding. No Company shall make any payment to any creditor of
any Unrestricted Subsidiary. All financial statements of each Unrestricted
Subsidiary distributed to any creditor of an Unrestricted Subsidiary shall
clearly establish the separateness of such Unrestricted Subsidiary from the
Companies.

          9.28.     Take-Out Financing.  The Borrower shall take any and every
                    ------------------                                        
action necessary or desirable, to the extent within the power of the Borrower,
so that the Take-Out Bank can, as soon as practicable after the Closing Date,
publicly sell or privately place the Refinancing Securities. If the Initial
Loans shall not have been refinanced in full prior thereto, the Borrower shall
agree that upon notice by the Take-Out Bank (a "Refinancing Securities Demand"),
                                                -----------------------------   
at any time and from time to time prior to the first anniversary of the Closing
Date, Holding and/or the Borrower will cause the issuance and sale of
Refinancing Securities upon such terms and conditions as specified in the
Refinancing Securities Demand; provided that (i) the interest rates (whether
                               --------                                     
floating or fixed) shall be determined by the Take-Out Bank in light of the then
prevailing market conditions; (ii) the maturity of any Refinancing Securities
shall not be earlier than the eighth anniversary of the Closing Date; (iii) the
Refinancing Securities will be issued pursuant to one or more indentures
substantially in the form of the Take-Out Bank's customary high yield indenture
and which shall contain such terms, conditions and covenants as are customary
for similar financing and as are reasonably satisfactory in all respects to the
takeout Bank and its counsel and the Borrower and its counsel; and (iv) all
other arrangements with respect to the Refinancing Securities shall be
reasonably satisfactory in all respects to the Take-Out Bank in light of the
then prevailing market conditions. Before offering common equity of Holding in
connection with the issuance and sale of Refinancing Securities of the Borrower,
the Take-Out Bank will consult with the Borrower regarding prevailing market
conditions and the advisability of issuing common equity to facilitate the
placement of such Refinancing Securities.

          Further, if it shall reasonably be determined by the Take-Out Bank
based on the prevailing market conditions that it is necessary and advisable to
sell the Refinancing Securities with an equity component, Holding shall issue
common equity to the purchasers of the Refinancing Securities in such amount as
is necessary in order for Holding and the Borrower to receive net proceeds from
the sale of the Refinancing Securities in an amount sufficient to repay the
Initial Loans in full; provided that in no event will Holding be required to
                       --------
issue common equity representing more than 5% of its outstanding common equity
(calculated on a fully-diluted basis) pursuant to this sentence.

          9.29.     Exchange of Term Notes.  Borrower will, on the fifth

          (i)  Execute and deliver, cause each Guarantor to execute and deliver,
     and cause a bank or trust company acting as trustee thereunder to execute
     and deliver, the Senior Subordinated Indenture, if such Senior Subordinated
     Indenture has not previously been executed and delivered;

          (ii) Execute and deliver to such holder or beneficial owner in
     accordance with the Senior Subordinated Indenture a note in the form
     attached to the Senior Subordinated Indenture (the "Exchange Notes")

     bearing interest as set forth therein in exchange for such Term Note dated
     the date of the issuance of such Exchange Note, payable to the order of
     such holder or owner, as the case may be, in the same principal 

                                     -69-

 
     amount as such Term Note (or portion thereof) being exchanged, and cause
     each Guarantor to endorse its guarantee thereon; and

          (iii)  Execute and deliver, and cause each Guarantor to execute and
     deliver, to such holder or owner, as the case may be, a Registration Rights
     Agreement in the form of Exhibit G, if such Registration Rights Agreement
                              ---------                                       
     has not previously been executed and delivered or, if such Registration
     Rights Agreement has previously been executed and delivered and such holder
     or owner is not already a party thereto, permit such holder or owner to
     become a party thereto.

          The Exchange Request shall specify the principal amount of the Term
Notes to be exchanged pursuant to this Section 9.31 which shall be at least
$5,000,000 and integral multiples of $500,000 in excess thereof.  Term Notes
delivered to Borrower under this Section 9.31 in exchange for Exchange Notes
shall be canceled by Borrower and the corresponding amount of the Term Loan
shall be deemed repaid and the Exchange Notes shall be governed by and construed
in accordance with the terms of the Senior Subordinated Indenture.

          The bank or trust company acting as trustee under the Senior
Subordinated Indenture shall at all times be a corporation organized and doing
business under the laws of the United States of America or the State of New
York, in good standing and having its principal offices in the Borough of
Manhattan, in The City of New York, which is authorized under such laws to
exercise corporate trust powers and is subject to supervision or examination by
Federal or State authority and which has a combined capital and surplus of not
less than $50,000,000.

          9.30.     Release of Covenants Upon Conversion.  Upon any conversion
                    ------------------------------------                      
of the Initial Loans into Term Loans pursuant to Section 2.02, Sections 9.06-
9.10, 9.14, 9.18, 9.20, and 9.23-9.27 of this Agreement shall no longer apply to

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

until the satisfaction in full of the Term Loan and the Term Notes and all other
Obligations due under this Agreement it shall, and shall cause each of its
Subsidiaries to, fully and timely perform all covenants in this Section 9A
required to be performed by any of them..

          (a) Limitation on Restricted Payments.  Borrower will not, and will
              ---------------------------------

unless, at the time of and after giving effect to such Restricted Payment:

          (a) no Default or Event of Default shall have occurred and be
     continuing or would occur as a consequence thereof;

          (b) Borrower would, at the time of such Restricted Payment and after
     giving pro forma effect thereto as if such Restricted Payment had been made
     at the beginning of the applicable fourquarter period, have been permitted
     to incur at least S 1.00 of additional Indebtedness pursuant to the Fixed
     Charge Coverage Ratio test set forth in the first paragraph of the Section
     9A(b); and

     Stock) or from the issue or sale of Disqualified Capital Stock or debt

     date of such redesignation up to the amount of the Restricted Investments
     made in such Subsidiary that reduced this clause (c) and 50% of the excess
     of the fair market value of Borrower's Investment in such Subsidiary as of
     the date of such redesignation over (1) the amount of the Restricted
     Investment that reduced this clause (c) and (2) any amounts that increased
     the amount available as a Permitted Investment provided that with respect
                                                    --------

     fair market value greater than $2.0 million, a resolution of the Board of
     Directors set forth in an Officers' Certificate certifying such value or

     deemed to constitute a Restricted Payment for purposes of this covenant or
     any other provision of this Agreement.

          (vii)  repurchases of Equity Interests deemed to occur upon exercise
     of stock options if such Equity Interests represent a portion of the
     exercise price of such options;

          (viii) the repurchase, redemption or other acquisition or retirement
     for value of the Exchange Notes pursuant to the optional redemption
     provisions of the Senior Subordinated Indenture; provided that the amount
                                                      --------                
     of any Equity Offering used to effect such a repurchase, redemption or
     other acquisition or retirement for value shall be excluded from the
     calculation made pursuant to clause (c) above;

          (ix)   the repurchase, redemption or other acquisition or retirement
     for value of the Exchange Notes pursuant to the provisions of the Senior
     Subordinated Indenture relating to the repurchase option available to
     holders of the Exchange Notes in the event of a Change of Control or an
     Asset Sale; provided that, as of the date of such repurchase, redemption or
                 --------                                                       
     other acquisition or retirement for value, no Default or Event of Default
     shall have occurred and be continuing or, with the passage of time, would
     occur as a consequence thereof,

          (x)    the payment of dividends or distributions to Holding to (I)
     fund cash interest payments on Indebtedness under the Holding's Bridge Loan
     Agreement commencing December 30, 2003 in accordance with the terms
     thereof, (II) pursuant to a tax allocation agreement in effect on the
     Closing Date, in amounts required by Holding to pay income taxes, and (111)
     in amounts required by Holding to pay administrative expenses not to exceed
     $2.0 million in any calendar year; and

          (xi)   other Restricted Payments made with Excess Unrestricted
     Subsidiary Disposition Proceeds.

                                     -72-

 
          The Board of Directors may designate any Subsidiary to be an
Unrestricted Subsidiary if such designation would not cause a Default, For
purposes of making such determination, all outstanding Investments by Borrower
and its Subsidiaries (except to the extent repaid in cash) in the Subsidiary so
designated will be deemed to be Restricted Payments at the time of such
designation and will reduce the amount available for Restricted Payments under
the first paragraph of this Section 9A(a). All such outstanding Investments will
be deemed to constitute Investments in an amount equal to the fair market value
of such Investments at the time of such designation. Such designation will only
be permitted if such Restricted Payment would be permitted at such time and if
such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

          If, at any time, any Unrestricted Subsidiary would fail to meet the
requirements in the definition of "Unrestricted Subsidiary" as an Unrestricted
Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for
purposes of this Agreement and any Indebtedness of such Unrestricted Subsidiary
shall be deemed to be incurred by a Subsidiary of Borrower as of such date (and,
if such Indebtedness is not permitted to be incurred as of such date under
Section 9A(b), the Borrower shall be in default of such covenant).  The Board of
Directors of Borrower may at any time designate any Unrestricted Subsidiary to
be a Subsidiary; provided that such designation shall be deemed to be an
                 --------                                               
incurrence of Indebtedness by a Subsidiary of the Borrower of any outstanding
Indebtedness of such Unrestricted Subsidiary and such designation shall only be
permitted if (i) such Indebtedness is permitted under Section 9A(b), calculated
on a pro forma basis as if such designation had occurred at the beginning of the
four-quarter reference period, and (ii) no Default or Event of Default would be
in existence following such designation.

          The amount of all Restricted Payments (other than cash) shall be the
fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by Borrower or such Subsidiary,
as the case may be, pursuant to the Restricted Payment.  The fair market value
of any non-cash Restricted Payment or any adjustment made pursuant to clause (c)
of the first paragraph of this Section 9A(a) shall be determined by the Board of
Directors whose resolution with respect thereto shall be delivered to the
Exchange Note Trustee, such determination to be based upon an opinion or
appraisal issued by an accounting, appraisal or investment banking firm of
national standing if such fair market value exceeds $10.0 million.  Not later
than the date of making any Restricted Payment, Borrower shall deliver to the
Exchange Note Trustee an Officers' Certificate stating that such Restricted
Payment is permitted and setting forth the basis upon which the calculations
required by this Section 9A(a) were computed.

          If any Restricted Investment is sold or otherwise liquidated or repaid
or any dividend or payment is received by Borrower or a Subsidiary and such
amounts may be credited to clause (c) of the first paragraph of this Section
9A(a), then such amounts will be credited only to the extent of amounts not
otherwise included in Consolidated Net Income and that do not otherwise increase
the amount available as a Permitted Investment.

- - -----                                                                     
directly or indirectly, create, incur, issue, assume, guarantee or otherwise
become directly or indirectly liable, contingently or otherwise, with respect to
(collectively, "incur") any Indebtedness (including Acquired Debt) and that
Borrower will not issue any Disqualified Capital Stock and will not permit any
of its Subsidiaries to issue any shares of preferred stock; provided, however,
                                                            --------  ------- 
that Borrower may incur Indebtedness (including Acquired Debt) or issue shares
of Disqualified Capital Stock and the Guarantors may incur Indebtedness or issue
Disqualified Capital Stock or preferred stock if the Fixed Charge Coverage Ratio
for Borrower's most recently ended four full fiscal quarters for which internal
financial statements are available immediately preceding the date on which such
additional Indebtedness is incurred or such Disqualified Capital Stock or
preferred stock is issued would have been at least 2.0 to 1.0, determined on a
pro forma basis (including a pro forma application of the net proceeds
therefrom), as if the additional Indebtedness had been incurred, or the
Disqualified Capital Stock or preferred stock had been issued, as the case may
be, at the beginning of such four-quarter period.

          The provisions of the first paragraph of this Section 9A(b) will not
apply to the incurrence of any of the following items of Indebtedness
(collectively, "Permitted Debt"):

                                     -73-

 
          (i)    the incurrence by Borrower of Indebtedness under Credit
     Facilities (and the guarantee thereof by the Guarantors); provided that the

     aggregate principal amount of all Indebtedness outstanding under this
     clause (i) after giving effect to such incurrence does not exceed an amount
     equal to $750.0 million (with letters of credit being deemed to have a
     principal amount equal to the maximum potential liability of Borrower and
     its Subsidiaries thereunder) less the amount of proceeds of Asset Sales
     applied to repay any such term Indebtedness or revolving Indebtedness if
     such repayment of revolving Indebtedness resulted in a corresponding
     commitment reduction (excluding any such payments to the extent refinanced
     at the time of repayment);

          (ii)   the incurrence by Borrower and its Subsidiaries of Existing
     Debt;

          (iii)  (A) the guarantee by Borrower or any of the Guarantors of
     Indebtedness of Borrower or a Subsidiary of Borrower or (B) the incurrence
     of Indebtedness of a Subsidiary to the extent that such Indebtedness is
     supported by a letter of credit, in each case that was permitted to be
     incurred by another provision of this covenant;

          (iv)   the incurrence by Borrower or any of its Subsidiaries of
     Indebtedness (including Capital Lease Obligations) to finance the
     acquisition (including by direct purchase, by lease or indirectly by the
     acquisition of the Capital Stock of a Person that becomes a Subsidiary as a
     result of such acquisition) or improvement of assets or property (real or
     personal) in an aggregate principal amount which, when aggregated with the
     principal amount of all other Indebtedness then outstanding pursuant to
     this clause (iv) and including all Permitted Refinancing Indebtedness
     incurred to refund, refinance or replace any Indebtedness incurred pursuant
     to this clause (iv), does not exceed an amount equal to 5% of Total Assets
     at the time of such incurrence;

          (v)    the incurrence by Borrower or any of its Subsidiaries of
     Permitted Refinancing Indebtedness in exchange for, or the net proceeds of
     which are used to reftind, refinance or replace Indebtedness (other than
     intercompany Indebtedness) that was permitted to be incurred under the
     first paragraph of this Section 9A(b) or clauses (ii), (iii) or (iv) of
     this paragraph;

          (vi)   the incurrence by Borrower or any of its Subsidiaries of
     intercompany Indebtedness between or among Borrower and any of its
     Subsidiaries; provided, however, that (i) if Borrower is the obligor on
                   --------  -------                                        
     such Indebtedness, such Indebtedness is expressly subordinated to the prior
     payment in full in cash of all Obligations with respect to the Exchange
     Notes and (ii)(A) any subsequent issuance or transfer of Equity Interests
     that results in any such Indebtedness being held by a Person other than
     Borrower or a Subsidiary thereof and (B) any sale or other transfer of any
     such Indebtedness to a Person that is not either Borrower or a Subsidiary
     thereof shall be deemed, in each case, to constitute an incurrence of such
     Indebtedness by Borrower or such Subsidiary, as the case may be, that was
     not permitted by this clause (vi);

          (vii)  the incurrence by Borrower or any of its Subsidiaries of
     Hedging Obligations that are incurred in the ordinary course of business
     for the purpose of risk management and not for the purpose of speculation;

          (viii) the incurrence by Borrower's Unrestricted Subsidiaries of Non-
     Recourse Debt, provided, however, that if any such Indebtedness ceases to
                    --------  -------                                         
     be Non-Recourse Debt of an Unrestricted Subsidiary, such event shall be
     deemed to constitute an incurrence of Indebtedness by a Subsidiary of
     Borrower that was not permitted by this clause (viii), and the issuance of
     preferred stock by Unrestricted Subsidiaries;

          (ix)   the incurrence of Indebtedness solely in respect of
     performance, surety and similar bonds or completion or performance
     guarantees (including, without limitation, performance guarantees pursuant
     to coal supply agreements or equipment leases and including letters of
     credit issued in support of such performance, surety and similar bonds), to
     the extent that such incurrence does not result in the incurrence of any
     obligation for the payment of borrowed money to others;

                                     -74-

 
          (x)    the incurrence of Indebtedness arising from agreements of
     Borrower or a Subsidiary providing for indemnification, adjustment of
     purchase price or similar obligations, in each case, incurred or assumed in
     connection with the disposition of any business, assets or a Subsidiary;
     provided, however, that (i) such Indebtedness is not reflected on the
     --------  -------
     balance sheet of Borrower or any Subsidiary (contingent obligations
     referred to in a footnote to financial statements and not otherwise
     reflected on the balance sheet will not be deemed to be reflected on such
     balance sheet for purposes of this clause (i)) and (h) the maximum
     assumable liability in respect of all such Indebtedness shall at no time
     exceed the gross proceeds including noncash proceeds (the fair market value
     of such noncash proceeds being measured at the time received and without
     giving effect to any subsequent changes in value) actually received by
     Borrower and its Subsidiaries in connection with such disposition; and

          (xi)   the incurrence by Borrower or any of its Subsidiaries of
     additional Indebtedness in an aggregate principal amount (or accreted
     value, as applicable) at any time outstanding, including all Permitted
     Refinancing Indebtedness incurred to refund, refinance or replace any
     Indebtedness incurred pursuant to this clause (xi), not to exceed the
     greater of (x) $50.0 million and (y) 2% of Total Assets.

          Borrower will not incur, and will not permit its Subsidiaries to
incur, any Indebtedness (including Permitted Debt) that is contractually
subordinated in right of payment to any other Indebtedness of Borrower or such
Subsidiary unless such Indebtedness is also contractually subordinated in right
of payment to the Exchange Notes or the guarantees thereof, as the case may be,
on substantially identical terms; provided, however, that no Indebtedness of
                                  --------  -------                         
Borrower or any Subsidiary shall be deemed to be contractually subordinated in
right of payment to any other Indebtedness of Borrower or any Subsidiary solely
by virtue of being unsecured.

          For purposes of determining compliance with this Section 9A(b), in the
event that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Debt described in clauses (i) through (xi) above or is
entitled to be incurred pursuant to the first paragraph of this Section 9A(b),
Borrower shall, in its sole discretion, classify or reclassify such item of
Indebtedness in any manner that complies with this Section 9A(b).  Accrual of
interest, accretion or amortization of original issue discount, the payment of
interest on any Indebtedness in the form of additional Indebtedness with the
same terms, and the payment of dividends on Disqualified Capital Stock in the
form of additional shares of the same class of Disqualified Capital Stock, will
not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified
Capital Stock for purposes of this covenant; provided, in each such case, that
                                             --------                         
the amount thereof is included in Fixed Charges of Borrower as accrued.

          (c) Limitation on Liens.  Borrower will not and will not permit any of
              -------------------                                               
its Subsidiaries to, directly or indirectly, create, incur, assume or otherwise
cause or suffer to exist or become effective any Lien of any kind (other than
Permitted Liens) upon any of their property or assets, now owned or hereafter
acquired, unless all payments due under this Agreement and the Loans are secured
on an equal and ratable basis with the obligations so secured until such time as
such obligations are no longer secured by a Lien.

          (d) Limitation on Dividend and Other Payment Restrictions Affecting
              ---------------------------------------------------------------
Subsidiaries.  Borrower will not, and will not permit any of its Subsidiaries
- - ------------                                                                 
to, directly or indirectly, create or otherwise cause or suffer to exist or
become effective any encumbrance or restriction on the ability of any Subsidiary
to (i)(a) pay dividends or make any other distributions to Borrower or any of
its Subsidiaries (1) on its Capital Stock or (2) with respect to any other
interest or participation in, or measured by, its profits, or (b) pay any
indebtedness owed to Borrower or any of its Subsidiaries, (ii) make loans or
advances to Borrower or any of its Subsidiaries or (iii) transfer any of its
properties or assets to Borrower or any of its Subsidiaries. However, the
foregoing restrictions will not apply to encumbrances or restrictions existing
under or by reason of (a) Existing Debt as in effect on the Closing Date, (b)
the Senior Credit Facility as in effect as of the date of the Indenture, and any
amendments, modifications, restatements, renewals, increases, supplements,
refundings, replacements or refinancings thereof, provided that such amendments,
                                                  --------                      
modifications, restatements, renewals, increases, supplements, refundings,
replacement or refinancings are no more restrictive, taken as a whole, with
respect to such dividend and other payment restrictions than those contained in
the Senior Credit Facility as in effect on the Closing Date, (c) this Agreement,
(d) applicable law or any applicable rule, regulation or order, (e) any
instrument governing Indebtedness or Capital Stock of a Person acquired by
Borrower or any of its 

                                     -75-

 
Subsidiaries as in effect at the time of such acquisition (except to the extent
such Indebtedness was incurred in connection with or in contemplation of such
acquisition), which encumbrance or restriction is not applicable to any Person,
or the properties or assets of any Person, other than the Person, or the
property or assets of the Person, so acquired, provided that, in the case of 
                                               --------      
Indebtedness, such Indebtedness was permitted by the terms of the Senior Note
Indenture to be incurred, (f) customary non-assignment provisions in leases and
other agreements entered into in the ordinary course of business and consistent
with past practices, (g) purchase money obligations for property acquired in the
ordinary course of business that impose restrictions of the nature described in
clause (iii) above on the property so acquired, (h) any agreement for the sale
of a Subsidiary that restricts distributions by that Subsidiary pending its
sale, (i) Permitted Refinancing Indebtedness, provided that the restrictions
                                              --------
contained in the agreements governing such Permitted Refinancing Indebtedness
are no more restrictive, taken as a whole, than those contained in the
agreements governing the Indebtedness being refinanced, (j) secured Indebtedness
otherwise permitted to be incurred pursuant to the provisions of Section 9A(c)
that limits solely the right of the debtor to dispose of the assets securing
such Indebtedness, (k) provisions with respect to the disposition or
distribution of assets or property in joint venture agreements and other similar
agreements entered into in the ordinary course of business, (1) restrictions on
cash or other deposits Or net worth imposed by customers or lessors under
contracts or leases entered into in the ordinary course of business and (m) any
encumbrances or restrictions imposed by any amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacements or
refinancings of the contracts, instruments or obligations referred to in clauses
(a) through (1) above, provided that such amendments, modifications,
                       --------          
restatements, renewals, increases, supplements, refundings, replacements or
refinancings are, in the good faith judgment of Borrower's Board of Directors,
not materially more restrictive in the aggregate with respect to such dividend
and other payment restrictions than those (considered as a whole) contained in
the dividend or other payment restrictions prior to such amendment,
modification, restatement, renewal, increase, supplement, refunding, replacement
or refinancing.

          (e) Merger, Consolidation, or Sale of Assets.  Borrower may not
              ----------------------------------------                   
consolidate or merge with or into (whether or not Borrower is the surviving
corporation), or sell, assign, transfer, lease, convey or otherwise dispose of
all or substantially all of its properties or assets in one or more related
transactions, to another corporation, Person or entity unless (i) Borrower is
the surviving corporation or the entity or the Person formed by or surviving any
such consolidation or merger (if other than Borrower) or to which such sale,
assignment, transfer, lease, conveyance or other disposition shall have been
made is a corporation organized or existing under the laws of the United States,
any state thereof or the District of Columbia; (ii) the entity or Person formed
by or surviving any such consolidation or merger (if other than Borrower) or the
entity or Person to which such sale, assignment, transfer, lease, conveyance or
other disposition shall have been made assumes all the obligations of Borrower
under the Registration Rights Agreement, the Notes and this Agreement pursuant
to documentation in a form reasonably satisfactory to the Administrative Agent;
(iii) immediately after such transaction no Default or Event of Default exists;
and (iv) except in the case of a merger of Borrower with or into a Wholly Owned
Subsidiary of Borrower, immediately after giving pro forma effect to such
transaction, as if such transaction had occurred at the beginning of the
applicable four-quarter period, (A) the entity surviving such consolidation or
merger would be permitted to incur at least $1.00 of additional Indebtedness
pursuant to the Fixed Charge Coverage Ratio test set forth in the first
paragraph of Section 9A(b) or (B) the Fixed Charge Coverage Ratio for Borrower
or the entity or Person formed by or surviving any such consolidation or merger
(if other than Borrower), or to which such sale, assignment, transfer, lease,
conveyance or other disposition shall have been made would, immediately after
giving pro forma effect thereto as if such transaction had occurred at the
beginning of the ap  plicable four-quarter period, not be less than such Fixed
Charge Coverage Ratio for Borrower and its Subsidiaries immediately prior to
such transaction. In addition, Borrower may not, directly or indirectly, lease
all or substantially all of its properties or assets, in one or more related
transactions, to any other Person. The provisions of this covenant will not be
applicable to a sale, assignment, transfer, conveyance or other disposition of
assets between or among Borrower and its Subsidiaries.

          Notwithstanding the foregoing clause (iv), (i) any Subsidiary may
consolidate with, merge into or transfer all or part of its properties and
assets to Borrower and (ii) Borrower may merge with an Affiliate that has no
significant assets or liabilities and was formed solely for the purpose of
changing the jurisdiction of organization of Borrower in another State of the
United States or the form of organization of Borrower so long as the amount of
Indebtedness of Borrower and its Subsidiaries is not increased thereby and
provided that the successor assumes all the 

                                     -76-

 
obligations of Borrower under the Registration Rights Agreement, the Notes and
this Agreement pursuant to documentation in a form reasonably satisfactory to
the Administrative Agent.

          (f) Transactions with Affiliates.  Borrower will not, and will not
              ----------------------------                                  
permit any of its Subsidiaries to, make any payment to, or sell, lease, transfer
or otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate (each of the foregoing, an "Affiliate Transaction"),
unless (i) such Affiliate Transaction is on terms that are materially no less
favorable to Borrower or the relevant Subsidiary than those that would have been
obtained in a comparable transaction by Borrower or such Subsidiary with an
unrelated Person and (ii) Borrower delivers to the Trustee (a) with respect to
any Affiliate Transaction or series of related Affiliate Transactions involving
aggregate consideration in excess of $2.0 million, a resolution of the Board of
Directors set forth in an Officers' Certificate certifying that such Affiliate
Transaction complies with clause (i) above and that such Affiliate Transaction
has been approved by a majority of the disinterested members of the Board of
Directors and (b) with respect to any Affiliate Transaction or series of related
Affiliate Transactions involving aggregate consideration in excess of $10.0
million, an opinion as to the fairness to the Holders of such Affiliate
Transaction from a financial point of view issued by an accounting, appraisal or
investment banking firm of national standing.  Notwithstanding the foregoing,
the following items shall not be deemed to be Affiliate Transactions:  (i)
transactions entered into pursuant to the terms of (a) the Haulage and Delivery
Agreement, (b) the Mitsui Marketing Agreement, (c) the MMI Service Agreement,
(d) the Ml-fl Leases, (e) the Bowie Sales Agency Agreement and (f) the
Technology Sharing Agreement, each as in effect on the Closing Date or as
thereafter amended, provided any such amendment does not materially and
                    --------                                           
adversely effect the rights of the Lenders under this Agreement or Holders of
the Exchange Notes under the Senior Subordinated Indenture, (ii) any employment
agreement or arrangement entered into by Borrower or any of its Subsidiaries or
any employee benefit plan available to employees of Borrower and its
Subsidiaries generally, in each case in the ordinary course of business and
consistent with the past practice of Borrower or such Subsidiary, (iii)
transactions between or among Borrower and/or its Subsidiaries, (iv) payment of
reasonable directors fees to Persons who are not otherwise Affiliates of
Borrower, (v) Restricted Payments that are permitted by this Agreement or
pursuant to the definition of Permitted Investments, (vi) indemnification
payments made to officers, directors and employees of Borrower or any Subsidiary
pursuant to charter, bylaw, statutory or contractual provisions; (vii)
transactions pursuant to the terms of the Transaction Documents in effect on the
dates of the closings of the Acquisitions, (viii) the provision by Borrower or
any Subsidiary to Triton of accounting and finance, legal, engineering,
marketing and other similar services in the ordinary course of business and (ix)
payments permitted pursuant to clause (x) under the second paragraph of Section
9A(a).

          (g) Limitation on Issuances and Sales of Equity Interests in Wholly

any of its Subsidiaries to, consummate an Asset Sale unless (i) Borrower (or the
Subsidiary, as the case may be) receives consideration at the time of such Asset
Sale at least equal to the fair market value as determined in good faith by
Borrower (evidenced by 

                                     -77-

 
a resolution of the Board of Directors set forth in an Officers' Certificate
delivered to the Senior Subordinated Note Trustee with respect to any Asset Sale

of any such assets pursuant to a customary novation agreement that releases
Borrower or such Subsidiary from further liability, (x) any securities, notes or
other obligations received by Borrower or any such Subsidiary from such
transferee that are contemporaneously (subject to ordinary settlement periods)
converted by Borrower or such Subsidiary into cash (to the extent of the cash

     lease or the holder or holders of such Indebtedness (or a trustee or agent
     on behalf of such holder or holders) to cause, such lease to be terminated

whereupon such amounts shall be immediately due and payable without presentment,
demand, protest or other formalities of any kind, all of which are hereby
expressly waived by Borrower, reduce any claim to judgment and take any other
action permitted by law; and (2) in the case of the occurrence of an Event of
Default referred to in clause (f) or (g) of this Section 10 with respect to the

automatically become immediately due and payable without presentment, demand,

          Section 11.    Agents.
                         ------ 

          11.01.    General Provisions.  Each of the Lenders and Agents hereby
                    ------------------                                        
irrevocably appoints Administrative Agent as its agent and authorizes
Administrative Agent to take such actions on its behalf and to exercise such
powers as are delegated to Administrative Agent by the terms hereof, together
with such actions and powers as are reasonably incidental thereto.
Administrative Agent agrees to give promptly to each Lender a copy of each
notice or other document received by it pursuant to any Credit Document (other
than any that are required to be delivered to the Lenders by any Obligor).

          The Lender or other financial institution serving as any Agent
hereunder shall have the same rights and powers in its capacity as a Lender as
any other Lender and may exercise the same as though it were not such Agent, and
such bank and its Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with any Company or other Affiliate
thereof as if it were not such Agent hereunder.

          No Agent shall have any duties or obligations except those expressly
set forth herein. Without limiting the generality of the foregoing, (a) no Agent
shall be subject to any fiduciary or other implied duties, regardless of whether
a Default has occurred and is continuing, (b) no Agent shall have any duty to
take any discretionary action or exercise any discretionary powers, except
discretionary rights and powers expressly contemplated hereby that such Agent is
required to exercise in writing by the Majority Lenders (or such other number or
percentage of the Lenders as shall be necessary under the circumstances as
provided in Section 12.04), and (c) except as expressly set forth herein, no
Agent shall have any duty to disclose, and shall not be liable for the failure
to disclose, any information relating to any Company that is communicated to or
obtained by the financial institution serving as such Agent or any of its
Affiliates in any capacity. No Agent shall be liable for any action taken or not
taken by it with the consent or at the request of the Majority Lenders (or such
other number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 12.04) or in the absence of its own gross
negligence or willful misconduct.  No 

                                     -80-

 
Agent shall be deemed to have knowledge of any Default unless and until written
notice thereof is given to Administrative Agent and such Agent by Borrower or a
Lender, and no Agent shall be responsible for or have any duty to ascertain or
inquire into (i) any statement, warranty or representation made in or in
connection with this Agreement or any other Credit Document, (ii) the contents
of any certificate, report or other document delivered hereunder or under any
other Credit Document or in connection herewith, (iii) the performance or
observance of any of the covenants, agreements or other terms or conditions set
forth herein, (iv) the validity, enforceability, effectiveness or genuineness of
this Agreement or any other Credit Document or any other agreement, instrument
or document, or (v) the satisfaction of any condition set forth in Section 7 or
elsewhere herein, other than to confirm receipt of items expressly required to
be delivered to such Agent.

          Each Agent shall be entitled to rely upon, and shall not incur any
liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing reasonably believed by it to be
genuine and to have been signed or sent by the proper Person. Each Agent also
may rely upon any statement made to it orally or by telephone and believed by it
to be made by the proper Person, and shall not incur any liability for relying
thereon. Each Agent may consult with legal counsel (who may be counsel for
Borrower), independent accountants and other experts reasonably selected by it,
and shall not be liable for any action taken or not taken by it in accordance
with the advice of any such counsel, accountants or experts. Each Agent may deem
and treat the payee of any Note as the owner thereof for all purposes unless a
written notice of assignment, negotiation or transfer thereof shall have been
filed with such Agent. Each Agent shall be fully justified in failing or
refusing to take any action under this Agreement or any other Credit Document
unless it shall first receive such advice or concurrence of the Majority Lenders
(or, if so specified by this Agreement, all 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. Each Agent shall in all cases be fully
protected in acting, or in refraining from acting, under this Agreement and the
other Credit Documents in accordance with a request of the Majority Lenders (or,
if so specified by this Agreement, all Lenders), and such request and any action
taken or failure to act pursuant thereto shall be binding upon all the Lenders
and all future holders of the Loans.

          Each Agent may perform any and all its duties and exercise its rights
and powers by or through any one or more sub-agents appointed by such Agent.
Each Agent and any such sub-agent may perform any and all its duties and
exercise its rights and powers through their respective Affiliates, directors,
officers, employees, agents and advisors ("Related Parties").  The exculpatory
                                           ---------------                    
provisions of the preceding paragraphs shall apply to any such sub-agent and to
the Related Parties of each Agent and any such sub-agent, and shall apply to
their respective activities in connection with the syndication of the credit
facilities provided for herein as well as activities as such Agent.

          Subject to the appointment and acceptance of a successor Agent as
provided in this paragraph, any Agent may resign at any time by notifying the
Lenders and Borrower. Upon any such resignation, the Majority Lenders shall have
the right to appoint a successor which, so long as no Default is continuing,
shall be reasonably acceptable to Borrower.  If no successor shall have been so
appointed by the Majority Lenders and shall have accepted such appointment
within 30 days after the retiring Agent gives notice of its resignation, then
the retiring Agent may, on behalf of the Lenders, appoint a successor Agent
which shall be a bank with an office in New York, New York, or an Affiliate of
any such bank. Upon the acceptance of its appointment as Agent hereunder by a
successor, such successor shall succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder.  The fees
payable by Borrower to a successor Agent shall be the same as those payable to
its predecessor unless otherwise agreed between Borrower and such successor.
After the Agent's resignation hereunder, the provisions of this Section I I
shall continue in effect for the benefit of such retiring Agent, its sub-agents
and their respective Related Parties in respect of any actions taken or omitted
to be taken by any of them while it was acting as such Agent.

          Each Lender acknowledges that it has, independently and without
reliance upon any Agent or any other Lender and based on such documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each Lender also acknowledges that it
will, independently and without reliance upon any Agent or any other Lender and
based on such documents and information as it shall from time to time deem
appropriate, continue to make its own decisions in taking or not taking action
under or based upon this 

                                     -81-

 
Agreement, any related agreement or any document furnished hereunder or
thereunder. No Agent shall be deemed a trustee or other fiduciary on behalf of
any party.

          11.02.    Indemnification.  Each Lender agrees to indemnify and hold
                    ---------------                                           
harmless each Agent (to the extent not promptly reimbursed under Section 12.03,
but without limiting the obligations of Borrower under Section 12.03), ratably
in accordance with the aggregate principal amount of the respective Commitments
of and/or Loans held by the Lenders, for any and all liabilities (including
pursuant to any Environmental Law), obligations, losses, damages, penalties,
actions, judgments, deficiencies, suits, costs, expenses (including reasonable
attorney's fees) or disbursements of any kind and nature whatsoever that may be
imposed on, incurred by or asserted against such Agent (including by any Lender)
arising out of or by reason of any investigation in or in any way relating to or
arising out of any Credit Document or any other documents contemplated by or
referred to therein for any action taken or omitted to be taken by such Agent
under or in respect of any of the Credit Documents or other such documents or
the transactions contemplated thereby (including the costs and expenses that
Borrower is obligated to pay under Section 12.03, but excluding, unless a
Default has occurred and is continuing, normal administrative costs and expenses
incident to the performance of its agency duties hereunder) or the enforcement
of any of the terms hereof or thereof or of any such other documents; provided,
                                                                      -------- 
however, that no Lender shall be liable for any of the foregoing to the extent
- - -------                                                                       
they are determined by a court of competent jurisdiction in a final and
nonappealable judgment to have resulted from the gross negligence or willful
misconduct of the party to be indemnified. The agreements set forth in this
Section 11.02 shall survive the payment of all Loans and other obligations
hereunder and shall be in addition to and not in lieu of any other
indemnification agreements contained in any other Credit Document.

          11.03.    Consents Under Other Credit Documents.  Except as otherwise
                    -------------------------------------                      
provided in this Agreement and the other Credit Documents, Administrative Agent
may, with the prior consent of the Majority Lenders (but not otherwise), consent
to any modification, supplement or waiver under any of the other Credit
Documents.

          Section 12.    Miscellaneous.
                         ------------- 

          12.01.    Waiver.  No failure on the part of any Creditor to exercise
                    ------                                                     
and no delay in exercising, and no course of dealing with respect to, any right,
power or privilege under any Credit Document shall operate as a waiver thereof,
nor shall any single or partial exercise of any right, power or privilege under
any Credit Document preclude any other or further exercise thereof or the
exercise of any other right, power or privilege.  The remedies provided herein
are cumulative and not exclusive of any remedies provided by law.

          12.02.    Notices.  All notices, requests and other communications
                    -------                                                 
provided for herein (including any modifications of, or waivers, requests or
consents under, this Agreement) shall be given or made in writing (including by
facsimile) delivered to the intended recipient at the "Address for Notices"
specified below its name on the signature pages hereof; or, as to any party, at
such other address as shall be designated by such party in a notice to each
other party. Except as otherwise provided in this Agreement, all such
communications shall be deemed to have been duly given when transmitted by
facsimile or personally delivered or, in the case of a mailed notice, upon
receipt, in each case given or addressed as aforesaid.  Any Notice of Borrowing
or Notice of Continuation/Conversion shall be deemed to have been received when
actually received.

                    ------------------------------                            
and severally, agree to pay or reimburse:

          (i)  the An-anger and Administrative Agent for all of their reasonable
     out-of-pocket costs and expenses (including the reasonable fees and
     expenses of legal counsel) in connection with (1) the negotiation,
     preparation, execution and delivery of the Credit Documents and the
     extension of credit hereunder, (2) the negotiation or preparation of any
     modification, supplement or waiver of any of the terms of any Credit
     Document (whether or not consummated or effective) and (3) the primary

     counsel) in connection with (1) any Default and any enforcement or
     collection proceedings resulting therefrom, including all manner of
     participation in or other involvement with (x) bankruptcy, insolvency,
     receivership, foreclosure, winding up or liquidation proceedings, (y)
     judicial or regulatory proceedings and (z) workout, restructuring or other
     negotiations or proceedings (whether or not the workout, restructuring or
     transaction contemplated thereby is consummated), (2) the enforcement of
     this Section 12.03 and (3) any documentary taxes; and

          (iii)  each of the Lenders and the Administrative Agent for all
     reasonable costs, expenses, taxes, assessments and other charges incurred
     in connection with any filing, registration, recording or perfection of any
     security interest contemplated by any Credit Document or any other document
     referred to therein.

          (b) The Obligors, jointly and severally, hereby agree to indemnify
each Creditor and their re spective Affiliates, directors, trustees, officers,
employees and agents (each, an "Indemnitee") from, and hold each of them
                                ----------                              
harmless against, and that no Indemnitee will have any liability for, any and
all Losses incurred by any of them (including any and all Losses incurred by
Administrative Agent or Arranger to any Lender, whether or not any Creditor is a
party thereto) directly or indirectly arising out of or by reason of or relating
to the negotiation, execution, delivery, performance, administration or
enforcement of any Credit Document, any of the transactions contemplated by the
Credit Documents, any breach by any Obligor of any representation, warranty,
covenant or other agreement contained in any of the Credit Documents in
connection with any of the Transactions or the use or proposed use of any of the
Loans, but excluding any such Losses to the extent finally determined by a court
of competent jurisdiction in a final and nonappealable judgment to have arisen
from the gross negligence or bad faith of the Indemnitee.

          Without limiting the generality of the foregoing, the Obligors,
jointly and severally, will indemnify each Creditor and each other Indemnitee
from, and hold each Creditor and each other Indemnitee harmless against, any
Losses described in the preceding sentence arising under any Environmental Law
as a result of (A) the past, present or future operations of any Company (or any
predecessor in interest to any Company), (B) the past, present or future
condition of any site or facility owned, operated, leased or used at any time by
any Company (or any such predecessor in interest), or (C) any Release or
threatened Release of any Hazardous Materials at, on, under or from any such
site or facility, including any such Release or threatened Release that shall
occur during any period when any Creditor shall be in possession of any such
site or facility following the exercise by such Creditor of any of its rights
and remedies hereunder; provided, however, that the indemnity hereunder shall be
                        --------  -------                                       
subject to the exclusions from indemnification set forth in the preceding
sentence.

          To the extent that the undertaking to indemnify and hold harmless set
forth in this Section 12.03 or any other provision of any Credit Document
providing for indemnification is unenforceable because it is violative of any
law or public policy or otherwise, the Obligors, jointly and severally, shall
contribute the maximum portion that each of them is permitted to pay and satisfy
under applicable law to the payment and satisfaction of all indemnified
liabilities incurred by any of the Persons indemnified hereunder.

          The Obligors also agree that no Indemnitee shall have any liability
(whether direct or indirect, in contract or tort or otherwise) for any Losses to
any Obligor or any Obligor' s security holders or creditors resulting from,
arising out of, in any way related to or by reason of any matter referred to in
any indemnification or expense reimbursement provisions set forth in this
Agreement or any other Credit Document, except to the extent that any Loss is
determined by a court of competent jurisdiction in a final nonappealable
judgment to have resulted from the gross negligence or bad faith of such
Indemnitee.

          The Obligors agree that, without the prior written consent of
Administrative Agent, Arranger and the Majority Lenders, which consent shall not
be unreasonably withheld, no Obligor will settle, compromise or consent to the
entry of any judgment in any pending or threatened Proceeding in respect of
which indemnification is reasonably likely to be sought under the
indemnification provisions of this Section 12.03 (whether or not any Indemnitee
is an actual or potential party to such Proceeding), unless such settlement,
compromise or consent includes an unconditional 

                                     -83-

 
written release of each Indemnitee from all liability arising out of such
Proceeding and does not include any statement as to an admission of fault,
culpability or failure to act by or on behalf of any Indemnitee and does not
involve any payment of money or other value by any Indemnitee or any injunctive
relief or factual findings or stipulations binding on any Indemnitee.

          12.04.    Amendments, Etc.  (i) Any provision of any Credit Document
                    ---------------                                           
may be amended, modified or supplemented by an instrument in writing signed by
the Obligors party thereto and the Majority Lenders, or by the Obligors party
thereto and Administrative Agent acting with the written consent of the Majority
Lenders, and any provision of any Credit Document may be waived by an instrument
in writing signed by the Obligors party thereto and the Majority Lenders, or by
the Obligors party thereto and Administrative Agent acting with the written
consent of the Majority Lenders; provided, however, that:
                                 --------  -------       

          (a) no amendment or waiver shall, unless by an instrument signed by
     all of the Lenders or by Administrative Agent acting with the written
     consent of each Lender:  (I) extend the scheduled final maturity of any
     Loan or Note, or reduce the rate of interest (other than any waiver of any
     increase in the interest rate pursuant to the second sentence of the
     definition of Applicable Spread) or fees thereon, or extend the time of
     payment of interest or fees thereon, or reduce the principal amount
     thereof, or make any change to the definition of Applicable Spread, (II)
     extend the final maturity of any of the Commitments (or reinstate any
     Commitment terminated pursuant to Section 10), (111) change the currency in
     which any Obligation is payable, (IV) amend the terms of this Section 12.04
     or Section 4.07, 5 or 11.03, (V) reduce the percentages specified in the
     definition of the term "Majority Lenders" or amend any provision of any
     Credit Document requiring the consent of all the Lenders or reduce any
     other percentage of the Lenders required to make any determinations or
     waive any rights hereunder or to modify any provision hereof (it being
     understood that, with the consent of the Majority Lenders, other additional
     extensions of credit pursuant to this Agreement may be, included in the
     determination of the Majority Lenders without notice to or consent of any
     other Lender or Agent on substantially the same basis as the Commitments
     (and related extensions of credit) are included on the Closing Date), (VI)
     release any Guarantor from its obligations under Section 6 (unless
     permitted by this Agreement), (VII) consent to the assignment or transfer
     by any Obligor of any of its rights and obligations under any Credit
     Document, (VIII) amend Section 12.03 or any other indemnification and
     expense reimbursement provision set forth in any Credit Document, (IX)
     modify the provisions of Sections 13 or 14 or any of the defined terms
     related thereto in any manner adverse to the Lenders, or (X) waive
     performance by Borrower of its obligations under, or consent to any
     departure from any of the terms and provisions of, Section 2. 1 0(iii) or
     (iv) (it being understood that any prepayment required by Section 2.10(i)
     or (ii) may be waived or amended by the Majority Lenders); and

          (b) any modification or supplement of or waiver with respect to
     Section 11 which affects any Agent in their respective capacities as such
     shall require the consent of such Agent.

          (ii) If, in connection with any proposed change, waiver, discharge or
termination of any of the provisions of this Agreement as contemplated by
Section 12.04(i)(a) (other than clause (I) of such section), the consent of the
Majority Lenders is obtained but the consent of one or more of such other
Lenders whose consent is required is not obtained, then Borrower shall have the
right to replace each such nonconsenting Lender or Lenders (so long as all non-
consenting Lenders are so replaced) with one or more Replacement Lenders
pursuant to Section 2.11 so long as at the time of such replacement, each such
Replacement Lender consents to the proposed change, waiver, discharge or
termination; provided, however, that Borrower shall not have the right to
             --------  -------                                           
replace a Lender solely as a result of the exercise of such Lender's rights (and
the withholding of any required consent by such Lender) pursuant to clause (I)
of Section 12.04(i)(a).

          12.05.    Successors and Assigns.  This Agreement shall be binding
                    ----------------------                                  
upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

                                     -84-

 
          12.06.    Assignments and Participations.  (a) No Obligor may assign
                    ------------------------------                            
its respective rights or obligations hereunder or under the Notes or any other
Credit Document without the prior written consent of all of the Lenders.

          (b) Each Lender may assign to any Eligible Person any of its Loans,
its Notes and its Com mitments (but only with the consent (which shall not be
unreasonably withheld, delayed or conditioned) of Borrower and Arranger);
provided, however, that (i) no such consent by Borrower or Arranger shall be
- - --------  -------                                                           
required in the case of any assignment to another Lender or any Lender's
Affiliate or an Approved Fund of any Lender (in which case, the assignee and
assignor Lenders shall give notice of the assignment to An-anger); (ii) no
consent of Borrower need be obtained if any Default shall have occurred and be
continuing; (iii) each assignment, other than to a Lender or any Lender's
Affiliate or an Approved Fund of any Lender and other than any assignment
effected by UBS AG or any of its Affiliates in connection with the syndication
of the Commitments and/or Loans, shall be in an aggregate amount at least equal
to $5.0 million unless the assigning Lender's exposure is reduced to $0 or
unless Borrower and An-anger otherwise agree and (iv) in no event may any such
assignment be made to any Obligor or any of its Affiliates without consent of
all Lenders. Any assignment of a Loan shall be effective only upon appropriate
entries with respect thereto being made in the Register (and each Note shall
expressly so provide).  Any assignment or transfer of a Loan shall be registered
on the Register only upon surrender for registration of assignment or transfer
of the Note evidencing such Loan (if a Note was issued in respect thereof),
accompanied by an instrument in writing substantially in the form of Exhibit F,
and upon consent thereto by Borrower and Arranger to the extent required above,
one or more new Notes (if requested by the New Lender) in the same aggregate
principal amount shall be issued to the designated assignee and the old Notes
shall be returned by Administrative Agent to Borrower marked "canceled".  Upon
execution and delivery by the assignee to Borrower and Arranger of an instrument
in writing substantially in the form of Exhibit F, and upon consent thereto by
Borrower and Arranger to the extent required above, and in the case of a Loan,
upon appropriate entries being made in the Register, the assignee shall have, to
the extent of such assignment (unless otherwise provided in such assignment with
the consent of Administrative Agent), the obligations, rights and benefits of a
Lender hereunder holding the Commitment(s) and Loans (or portions thereof)
assigned to it (in addition to the Commitment(s) and Loans, if any, theretofore
held by such assignee) and the assigning Lender shall, to the extent of such
assignment, be released from the Commitment(s) (or portion(s) thereof) so
assigned.  Upon any such assignment (other than to a Lender or any Affiliate of
a Lender or an Approved Fund of any Lender and other than any assignment by UBS
AG or any of its Affiliates) the assignee Lender shall pay a fee of $3,500 to
Administrative Agent.  Upon any such assignment, certain rights and obligations
of the assigning Lender shall survive as set forth in Section 12.07.

          (c) A Lender may sell or agree to sell to one or more other Persons a
participation in all or any part of any Loans held by it, or in its Commitments,
in which event each purchaser of a participation (a "Participant") shall be
                                                     -----------           
entitled to the rights and benefits of the provisions of Section 5 (provided,
                                                                    -------- 
however, that no Participant shall be entitled to receive any greater amount
- - -------                                                                     
pursuant to Section 5 than the transferor Lender would have been entitled to
receive in respect of the participation effected by such transferor Lender had
no participation occurred) with respect to its participation in such Loans and
Commitments as if such Participant were a "Lender" for purposes of said Section,
but, except as otherwise provided in Section 4.07(c), shall not have any other
rights or benefits under this Agreement or any Note or any other Credit Document
(the Participants rights against such Lender in respect of such participation to
be those set forth in the agreements executed by such Lender in favor of the
Participant). All amounts payable by Borrower to any Lender under Section 5 in
respect of Loans and its Commitments shall be no greater than the amount that
would have applied if such Lender had not sold or agreed to sell any
participation in such Loans and Commitments, and as if such Lender were funding
each of such Loan and Commitments in the same way that it is funding the portion
of such Loan and Commitments in which no participations have been sold. In no
event shall a Lender that sells a participation agree with the Participant to
take or refrain from taking any action hereunder or under any other Credit
Document, except that such Lender may agree with the Participant that it will
not, without the consent of the Participant, agree to any modification or
amendment set forth in subclauses (1), (11), (111) or (VIII) of clause (a) of
the proviso to Section 12.04.

          (d) In addition to the assignments and participations permitted under
the foregoing provisions of this Section 12.06, any Lender may assign and pledge
all or any portion of its Loans and its Notes to any United States Federal
Reserve Bank as collateral security pursuant to Regulation A of the Board of
Governors of the Federal 

                                     -85-

 
Reserve System and any Operating Circular issued by such Federal Reserve Bank
and, in the case of a Lender that is an investment fund, any such Lender may
assign or pledge all or any portion of its Loans and its Notes to its trustee in
support of its obligations to its trustee, without notice to or consent of
Borrower, Administrative Agent or Arranger. No such assignment shall release the
assigning Lender from its obligations hereunder.

          (e) A Lender may furnish any information concerning any Company in the
possession of such Lender from time to time to assignees and participants
(including prospective assignees and participants) subject, however, to the
provisions of Section 12.11.  In addition, each of Administrative Agent and
Arranger may furnish any information concerning any Obligor or any of its
Affiliates in Administrative Agent's or Arranger's possession to any Affiliate
of Administrative Agent or Arranger, subject, however, to the provisions of
Section 12.11.  The Obligors shall assist any Lender in effectuating any
assignment or participation pursuant to this Section 12.06 (including during
syndication) in whatever manner such Lender reasonably deems necessary,
including participation in meetings with prospective transferees.

          12.07.    Survival.  The obligations of the Obligors under Sections
                    --------                                                 
5.01, 5.05, 5.06 and 12.03, the obligations of each Guarantor under Section
6.03, and the obligations of the Lenders under Sections 5.06 and 11.02, shall
survive the repayment of the Loans and the termination of the Commitments and,
in the case of any Lender that may assign any interest in its Commitments or
Loans hereunder, shall (to the extent relating to such time as it was a Lender)
survive the making of such assignment, notwithstanding that such assigning
Lender may cease to be a "Lender" hereunder. In addition, each representation
and warranty made, or deemed to be made by a notice of any extension of credit,
herein or pursuant hereto shall be considered to have been relied upon by the
other parties hereto and shall survive the execution and delivery of this
Agreement and the Notes and the making of any extension of credit hereunder,
regardless of any investigation made by any such other party or on its behalf
and notwithstanding that Administrative Agent or any Lender may have had notice
or knowledge of any Default or incorrect representation or warranty.

          12.08.    Captions.  The table of contents and captions and section
                    --------                                                 
headings appearing herein are included solely for convenience of reference and
are not intended to affect the interpretation of any provision of this
Agreement.

          12.09.    Counterparts; Interpretation; Effectiveness.  This Agreement
                    -------------------------------------------                 
may be executed in counterparts (and by different parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract.  This Agreement and any
separate letter agreements with respect to fees payable to Administrative Agent
constitute the entire contract among the parties relating to the subject matter
hereof and supersede any and all previous agreements and understandings, oral or
written, relating to the subject matter hereof, other than the indemnity,
confidentiality, waiver of jury trial and governing law provisions of the
Commitment Letter, which are not superseded and survive.  Except as provided in
Section 7.01, this Agreement shall become effective when it shall have been
executed by Administrative Agent and when Administrative Agent shall have
received counterparts hereof which, when taken together, bear the signatures of
each of the other parties hereto, and thereafter shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and
assigns.  Delivery of an executed counterpart of a signature page of this
Agreement by telecopy shall be effective as delivery of a manually executed
counterpart of this Agreement.

          12.10.    Governing Law, Submission to Jurisdiction; Waivers, Etc.
                    -------------------------------------------------------  
Each Credit Document shall be governed by, and construed in accordance with, the
law of the State of New York, without regard to the principles of conflicts of
laws thereof (except in the case of the other Credit Documents, to the extent
otherwise expressly stated therein). Each Obligor hereby irrevocably and
unconditionally: (I) submits for itself and its Property in any Proceeding
relating to any Credit Document to which it is a party, or for recognition and
enforcement of any judgment in respect thereof, to the non-exclusive general
jurisdiction of the Supreme Court of the State of New York sitting in New York
County, the courts of the United States of America for the Southern District of
New York, and appellate courts from any thereof; (H) consents that any such
Proceeding may be brought in any such court and waives trial by jury and any
objection that it may now or hereafter have to the venue of any such Proceeding
in any such court or that such Proceeding was brought in an inconvenient court
and agrees not to plead or claim the same; (III) agrees that service 

                                     -86-

 
of process in any such Proceeding may be effected by mailing a copy thereof by
registered or certified mail (or any substantially similar form of mail),
postage prepaid, to Borrower at its address set forth in Section 12.02 or at
such other address of which Administrative Agent shall have been notified
pursuant thereto; and (IV) agrees that nothing herein shall affect the right to
effect service of process in any other manner permitted by law or shall limit
the right to sue in any other jurisdiction.

          12.11.    Confidentiality.  Each Lender agrees to keep information
                    ---------------                                         
obtained by it pursuant hereto and the other Credit Documents identified as
confidential in writing at the time of delivery confidential in accordance with
such Lender's customary practices and agrees that it will only use such
information in connection with the transactions contemplated by this Agreement
and not disclose any of such information other than (a) to such Lender's
employees, representatives, directors, attorneys, auditors, agents, professional
advisors, trustees or affiliates who are advised of the confidential nature of
such information or to any direct or indirect contractual counterparty in swap
agreements or such contractual counterparty's professional advisor (so long as
such contractual counterparty or professional advisor to such contractual
counterparty agrees to be bound by the provision of this Section 12.11), (b) to
the extent such information presently is or hereafter becomes available to such
Lender on a non-confidential basis from any source of such information that is
in the public domain at the time of disclosure, (c) to the extent disclosure is
required by law (including applicable securities laws), regulation, subpoena or
judicial order or process (provided that notice of such requirement or order
                           --------                                         
shall be promptly furnished to Borrower unless such notice is legally
prohibited) or requested or required by bank, securities, insurance or
investment company regulations or auditors or any administrative body or
commission (including the Securities Valuation Office of the National
Association of Insurance Commissioners) to whose jurisdiction such Lender may be
subject, (d) to any rating agency to the extent required in connection with any
rating to be assigned to such Lender, (e) to assignees or participants or
prospective assignees or participants who agree to be bound by the provisions of
this Section 12.11, (f) to the extent required in connection with any litigation
between any Obligor and any Lender with respect to the Loans or this Agreement
and the other Credit Documents or (g) with Borrower's prior written consent.

          12.12.    Independence of Representations, Warranties and Covenants.
                    ---------------------------------------------------------  
The representations, warranties and covenants contained herein shall be
independent of each other and no exception to any representation, warranty or
covenant shall be deemed to be an exception to any other representation,
warranty or covenant contained herein unless expressly provided, nor shall any
such exception be deemed to permit any action or omission that would be in
contravention of applicable law.  Notwithstanding anything herein to the
contrary, any matter identified on a Schedule to this Agreement shall be deemed
to be set forth on all other Schedules to this Agreement for purposes of
determining compliance with any of the representations, warranties or covenants
contained herein.

          12.13.    Severability.  Wherever possible, each provision of this
                    ------------                                            
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be prohibited by or
invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity, without invalidating the remainder of
such provisions or the remaining provisions of this Agreement.

          12.14.    Acknowledgments.  The Obligors hereby acknowledge that: (a)
                    ---------------                                            
each of them has been advised by counsel in connection with the negotiation,
execution and delivery of the Credit Documents; (b) no Creditor has any
fiduciary or similar relationship to any Obligor and the relationship between
the Creditors on the one hand, and the Obligors, on the other hand, is solely
that of debtor and creditor; and (c) no joint venture exists among the Creditors
or among the Obligors and the Creditors.

          Section 13.    Subordination.
                         ------------- 

          (1) Loans and Notes Subordinated to Senior Indebtedness.  Borrower
              ---------------------------------------------------           
covenants and agrees, and the Agents and each Lender by its acceptance thereof
likewise covenant and agree, that all Loans and Notes shall be issued subject to
the provisions of this Section 13; and each person holding any Loan or Note,
whether upon original issue or upon transfer, assignment or exchange thereof,
accepts and agrees that all payments of the principal of and interest on the
Loans and Notes by Borrower shall, to the extent and in the manner set forth in
this Section 13, be 

                                     -87-

 
subordinated and junior in right of payment to the prior payment in full in cash
of all amounts payable under Senior Indebtedness.

          (2)  No Payment on Loans and Notes in Certain Circumstances, Payment
               ---------------------------------------------------------------
Held in Trust.
- - ------------- 

          (A)  No Payments in Certain Circumstances.  No direct or indirect
               ------------------------------------                        
payment (excluding any payment or distribution of Permitted Junior Securities)
by or on behalf of Borrower of principal of or interest on the Loans and Notes,
whether pursuant to the terms of the Loans or Notes, upon acceleration, pursuant
to an Offer to Purchase or otherwise, shall be made if, at the time of such
payment, there exists a default in the payment of all or any portion of the
obligations on any Designated Senior Indebtedness, whether at maturity, on
account of mandatory redemption or prepayment, acceleration or otherwise, and
such default shall not have been cured or waived or the benefits of this
sentence waived by or on behalf of the holders of such Designated Senior
Indebtedness. In addition, during the continuance of any non-payment event of
default with respect to any Designated Senior Indebtedness pursuant to which the
maturity thereof may be immediately accelerated, and upon receipt by the
Administrative Agent of written notice (a "Payment Blockage Notice") from the
                                           -----------------------           
holder or holders of such Designated Senior Indebtedness or the trustee or agent
acting on behalf of such Designated Senior Indebtedness, then, unless and until
such event of default has been cured or waived or has ceased to exist or such
Designated Senior Indebtedness has been discharged or repaid in full in cash or
the benefits of these provisions have been waived by the holders of such
Designated Senior Indebtedness, no direct or indirect payment (excluding any
payment or distribution of Permitted Junior Securities) shall be made by or on
behalf of Borrower of principal of or interest on the Loans or Notes to such
Holders, during a period (a "Payment Blockage Period") commencing on the date of
                             -----------------------                            
receipt of such notice by the Administrative Agent and ending 179 days
thereafter.

          Notwithstanding anything herein or in the Loans Or Notes to the
contrary, (x) in no event shall a Payment Blockage Period extend beyond 179 days
from the date the Payment Blockage Notice in respect thereof was given, (y)
there shall be a period of at least 181 consecutive days in each 360-day period
when no Payment Blockage Period is in effect and (z) not more than one Payment
Blockage Period may be commenced with respect to the Loans or Notes during any
period of 360 consecutive days. No event of default that existed or was
continuing on the date of commencement of any Payment Blockage Period with
respect to the Designated Senior Indebtedness initiating such Payment Blockage
Period (to the extent the holder of Designated Senior Indebtedness, or trustee
or agent, giving notice commencing such Payment Blockage Period had knowledge of
such existing or continuing event of default) may be, or be made, the basis for
the commencement of any other Payment Blockage Period by the holder or holders
of such Designated Senior Indebtedness or the trustee or agent acting on behalf
of such Designated Senior Indebtedness, whether or not within a period of 360
consecutive days, unless such event of default has been cured or waived for a
period of not less than 90 consecutive days.

          (B)  Payments Held in Trust.  In the event that, notwithstanding the
               ----------------------                                         
foregoing, any payment shall be received by the Arranger or any Lender when such
payment is prohibited by Section 13(2)(A), such payment shall be held in trust
for the benefit of, and shall be paid over or delivered to, the holders of
Designated Senior Indebtedness or their respective representatives, or to the
trustee or trustees under any indenture pursuant to which any of such Designated
Senior Indebtedness may have been issued, as their respective interests may
appear, but only to the extent that, upon notice from the Administrative Agent
to the holders of Designated Senior Indebtedness that such prohibited payment
has been made, the holders of the Designated Senior Indebtedness (or their
representative or representatives or a trustee) notify the Administrative Agent
in writing of the amounts then due and owing on the Designated Senior
Indebtedness, if any, and only the amounts specified in such notice to the
Administrative Agent shall be paid to the holders of Designated Senior
Indebtedness.

          (3)  Payment Over of Proceeds upon Dissolution, Etc.
               ---------------------------------------------- 

          (A)  Payment Over.  Upon any payment or distribution of assets or
               ------------                                                
securities of Borrower of any kind or character, whether in cash, property or
securities (excluding any payment or distribution of Permitted Junior
Securities), upon any dissolution or winding-up or liquidation or reorganization
of Borrower, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all Senior Indebtedness shall first be paid

                                     -88-

 
in full in cash before the Lenders or An-anger on behalf of such Lenders shall
be entitled to receive any payment by Borrower of the principal of or interest
on the Loans or Notes, or any payment by Borrower to acquire any of the Loans or
Notes for cash, property or securities, or any distribution with respect to the
Loans or Notes of any cash, property or securities (excluding any payment or
distribution of Permitted Junior Securities). Before any payment may be made by,
or on behalf of, Borrower of the principal of or interest on the Loans or Notes
upon any such dissolution or winding-up or liquidation or reorganization, any
payment or distribution of assets or securities of Borrower of any kind or
character, whether in cash, property or securities (excluding any payment or
distribution of Permitted Junior Securities), to which the Lenders or the
Administrative Agent on their behalf would be entitled, but for the
subordination provisions of this Agreement, shall be made by Borrower or by any
receiver, trustee in bankruptcy, liquidation trustee, agent or other Person
making such payment or distribution, directly to the holders of the Senior
Indebtedness (pro rata to such holders on the basis of the respective amounts of
              --- ----                                                          
Senior Indebtedness held by such holders) or their representatives or to the
trustee or trustees or agent or agents under any agreement or indenture pursuant
to which any of such Senior Indebtedness may have been issued, as their
respective interests may appear, to the extent necessary to pay all such Senior
Indebtedness in full in cash after giving effect to any prior or concurrent
payment, distribution or provision therefor to or for the holders of such Senior
Indebtedness.

          (B) Payments Held in Trust.  In the event that, notwithstanding the
              ----------------------                                         
foregoing provision prohibiting such payment or distribution, any payment or
distribution of assets or securities of Borrower of any kind or character,
whether in cash, property or securities (excluding any payment or distribution
of Permitted Junior Securities), shall be received by the Administrative Agent
or any Lender at a time when such payment or distribution is prohibited by
Section 13(3)(A) and before all obligations in respect of Senior Indebtedness
are paid in full in cash, or payment provided for, such payment or distribution
shall be received and held in trust for the benefit of, and shall be paid over
or delivered to the holders of Senior Indebtedness (pro rata to such holders on
                                                    --- ----                   
the basis of the respective amounts of Senior Indebtedness held by such holders)
or their respective representatives, or to the trustee or trustees or agent or
agents under any indenture pursuant to which any of such Senior Indebtedness may
have been issued, as their respective interests may appear, for application to
the payment of Senior Indebtedness remaining unpaid until all such Senior
Indebtedness has been paid in full in cash after giving effect to any prior or
concurrent payment, distribution or provision therefor to or for the holders of
such Senior Indebtedness.

          The consolidation of Borrower with, or the merger of Borrower with or
into, another corporation or the liquidation or dissolution of Borrower
following the conveyance or transfer of its property as an entirety, or
substantially as an entirety, to another corporation upon the terms and
conditions provided in Section 9A(e) shall not be deemed a dissolution, winding-
up, liquidation or reorganization for the purposes of this Section 13(3)(B) if
such other corporation shall, as a part of such consolidation, merger,
conveyance or transfer, comply with the conditions stated in Section 9A(e).

          (4) Subrogation.  Upon the payment in full in cash of all Senior
              -----------                                                 
Indebtedness, or provision for payment, the Lenders shall be subrogated to the
rights of the holders of Senior Indebtedness to receive payments or
distributions of cash, property or securities of Borrower made on such Senior
Indebtedness until the principal of and interest on the Loans and Notes shall be
paid in full in cash; and, for the purposes of such subrogation, no payments or
distributions to the holders of the Senior Indebtedness of any cash, property or
securities to which the Lenders or the Administrative Agent on their behalf
would be entitled except for the provisions of this Section 13, and no payment
over pursuant to the provisions of this Section 13 to the holders of Senior
Indebtedness by Lenders or the Administrative Agent on their behalf shall, as
between Borrower, its creditors other than holders of Senior Indebtedness, and
the Lenders, be deemed to be a payment by Borrower to or on account of the
Senior Indebtedness. It is understood that the provisions of this Section 13 are
and are intended solely for the purpose of defining the relative rights of the
Lenders, on the one hand, and the holders of the Senior Indebtedness, on the
other hand.

          If any payment or distribution to which the Lenders would otherwise
have been entitled but for the provisions of this Section 13 shall have been
applied, pursuant to the provisions of this Section 13, to the payment of all
amounts payable under Senior Indebtedness, then and in such case, the Lenders
shall be entitled to receive from the holders of such Senior Indebtedness any
payments or distributions received by such holders of Senior Indebtedness in
excess of the amount required to make payment in full, or provision for payment,
of such Senior Indebtedness.

                                     -89-

 
          (5) Obligations of Borrower Unconditional.  Nothing contained in this
              -------------------------------------                            
Section 13 or elsewhere in this Agreement or in the Notes is intended to or
shall impair, as among Borrower and the Lenders, the obligation of Borrower,
which is absolute and unconditional, to pay to the Lenders the principal of and
interest on the Loans and Notes as and when the same shall become due and
payable in accordance with their terms, or is intended to or shall affect the
relative rights of the Lenders and creditors of Borrower other than the holders
of the Senior Indebtedness, nor shall anything herein or therein prevent the
Lenders or the Administrative Agent on their behalf from exercising all remedies
otherwise permitted by applicable law upon default under this Agreement, subject
to the rights, if any, under this Section 13 of the holders of the Senior
Indebtedness in respect of cash, property or securities of Borrower received
upon the exercise of any such remedy.

          Without limiting the generality of the foregoing, nothing contained in
this Section 13 shall restrict the right of the Administrative Agent or the
Lenders to take any action to declare the Securities to be due and payable prior
to their stated maturity pursuant to Section 10 or to pursue any rights or
remedies hereunder; provided, however, that all Senior Indebtedness then due and
                    --------  -------                                           
payable shall first be paid in full before the Lenders or the Administrative
Agent is entitled to receive any direct or indirect payment from Borrower of
principal of or interest on the Loans and Notes.

          (6) Notice to Arrange.  Borrower shall give prompt written notice to
              -----------------                                               
the Administrative Agent of any fact known to Borrower which would prohibit the
making of any payment to or by the Administrative Agent in respect of the Loans
or Notes pursuant to the provisions of this Section 13.  The Administrative
Agent shall not be charged with knowledge of the existence of any event of
default with respect to any Senior Indebtedness or of any other facts which
would prohibit the making of any payment to or by the Administrative Agent
unless and until the Administrative Agent shall have received notice in writing
to that effect signed by an Officer of Borrower, or by a holder of Senior
Indebtedness or trustee or agent therefor; and prior to the receipt of any such
written notice, the Administrative Agent shall be entitled to assume that no
such facts exist; provided, however, that if the Administrative Agent shall not
                  --------  -------                                            
have received the notice provided for in this Section 13(6) at least two
Business Days prior to the date upon which by the terms of this Agreement any
moneys shall become payable for any purpose (including, without limitation, the
payment of the principal of or interest on any Loan or Note), then, regardless
of anything herein to the contrary, the Administrative Agent shall have full
power and authority to receive any moneys from Borrower and to apply the same to
the purpose for which they were received, and shall not be affected by any
notice to the contrary which may be received by it on or after such prior date.
Nothing contained in this Section 13(6) shall limit the right of the holders of
Senior Indebtedness to recover payments as contemplated by Section 13(3).  The
Administrative Agent shall be entitled to rely on the delivery to it of a
written notice by a Person representing himself or itself to be a holder of any
Senior Indebtedness (or a trustee on behalf of, or other representative of, such
holder) to establish that such notice has been given by a holder of such Senior
Indebtedness or a trustee or representative on behalf of any such holder.

          In the event that the Administrative Agent determines in good faith
that any evidence is required with respect to the right of any Person as a
holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Section 13, the Administrative Agent may request such Person to
furnish evidence to the reasonable satisfaction of the Administrative Agent as
to the amount of Senior Indebtedness held by such Person, the extent to which
such Person is entitled to participate in such payment or distribution and any
other facts pertinent to the rights of such Person under this Section 13, and if
such evidence is not furnished, the Administrative Agent may defer any payment
to such Person pending judicial determination as to the right of such Person to
receive such payment.

          (7) Reliance on Judicial Order or Certificate of Liquidating Agent.
              --------------------------------------------------------------  
Upon any payment or distribution of assets or securities referred to in this
Section 13, the Administrative Agent and the Lenders shall be entitled to rely
upon any order or decree made by any court of competent jurisdiction in which
bankruptcy, dissolution, winding-up, liquidation or reorganization proceedings
are pending, or upon a certificate of the receiver, trustee in bankruptcy,
liquidating trustee, agent or other person making such payment or distribution,
delivered to the Administrative Agent or to the Lenders for the purpose of
ascertaining the persons entitled to participate in such distribution, the
holders of the Senior Indebtedness and other indebtedness of Borrower, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Section 13.

                                     -90-

 
          (8)  Administrative Agent's Relation to Senior Indebtedness.  The
               ------------------------------------------------------      
Administrative Agent shall be entitled to all the rights set forth in this
Section 13 with respect to any Senior Indebtedness which may at any time be held
by it in its individual or any other capacity to the same extent as any other
holder of Senior Indebtedness, and nothing in this Agreement shall deprive the
Administrative Agent of any of its rights as such holder.

          With respect to the holders of Senior Indebtedness, the Administrative
Agent undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Section 13, and no implied
covenants or obligations with respect to the holders of Senior Indebtedness
shall be read into this Agreement or the Notes against the Administrative Agent.
The Administrative Agent shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness (except as provided in Section 13(3)(B)). The
Administrative Agent shall not be liable to any such holders if the
Administrative Agent shall in good faith mistakenly pay over or distribute to
Lenders or to Borrower or to any other person cash, property or securities to
which any holders of Senior Indebtedness shall be entitled by virtue of this
Section 13 or otherwise.

          (9)  Subordination Rights Not Impaired by Acts or Omissions of
               ---------------------------------------------------------
Borrower or Holders of Senior Indebtedness. No right of any present or future
- - ------------------------------------------
holders of any Senior Indebtedness to enforce subordination as provided herein
shall at any time in any way be prejudiced or impaired by any act or failure to
act on the part of Borrower or by any act or failure to act, in good faith, by
any such holder, or by any noncompliance by Borrower with the terms of this
Agreement, regardless of any knowledge thereof which any such holder may have or
otherwise be charged with. The provisions of this Section 13 are intended to be
for the benefit of, and shall be enforceable directly by, the holders of Senior
Indebtedness.

          (10) Lenders Authorize Administrative Agent To Effectuate
               ----------------------------------------------------
Subordination of Loans and Notes. Each Lender by his acceptance of Loans and
- - --------------------------------                                            
Notes authorizes and expressly directs the Administrative Agent on his behalf to
take such action as may be necessary or appropriate to effectuate the
subordination provided in this Section 13, and appoints the Administrative Agent
his attorney-in-fact for such purposes, including, in the event of any
dissolution, winding-up, liquidation or reorganization of Borrower (whether in
bankruptcy, insolvency, receivership, reorganization or similar proceedings or
upon an assignment for the benefit of creditors or otherwise) tending towards
liquidation of the business and assets of Borrower, the filing of a claim for
the unpaid balance of its Loans and Notes in the form required in those
proceedings.

          (11) This Section Not To Prevent Events of Default.  The failure to
               ---------------------------------------------                 
make a payment on account of principal of or interest on the Loans or Notes by
reason of any provision of this Section 13 shall not be construed as preventing
the occurrence of an Event of Default specified in Section 10.

          (12) Administrative Agent's Compensation Not Prejudiced.  Nothing in
               --------------------------------------------------             
this Section 13 shall apply to amounts due to the Administrative Agent pursuant
to other sections in this Agreement.

          (13) No Waiver of Subordination Provisions.  Without in any way
               -------------------------------------                     
limiting the generality of Section 13(9), the holders of Senior Indebtedness
may, at any time and from time to time, without the consent of or notice to the
Administrative Agent or the Lenders, without incurring responsibility to the
Lenders and without impairing or releasing the subordination provided in this
Section 13 or the obligations hereunder of the Lenders to the holders of Senior
Indebtedness, do any one or more of the following:  (a) change the manner, place
or terms of payment or extend the time of payment of, or renew or alter, Senior
Indebtedness or any instrument evidencing the same or any agreement under which
Senior Indebtedness is outstanding or secured; (b) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (c) release any Person liable in any manner for the collection of
Senior Indebtedness; and (d) exercise or refrain from exercising any rights
against Borrower and any other Person.

          (14) Acceleration of Loans and Notes.  If payment of the Loans or
               -------------------------------                             
Notes is accelerated because of an Event of Default, Borrower shall promptly
notify holders of the Senior Indebtedness of the acceleration.

          14.01.    Guarantee Obligations Subordinated to Guarantor Senior
                    ------------------------------------------------------
Indebtedness.  Each Guarantor covenants and agrees, and the Agents and each
- - ------------                                                               
Lender by its acceptance thereof likewise covenant and agree, that the Guarantee
shall be issued subject to the provisions of this Section 14; and each Person
holding any Loan or Note, whether upon original issue or upon transfer,
assignment or exchange thereof, accepts and agrees that all payments of the
principal of and interest on the Loans or Notes pursuant to the Guarantee made
by or on behalf of any Guarantor shall, to the extent and in the manner set
forth in this Section 14, be subordinated and junior in right of payment to the
prior payment in full in cash of all amounts payable under Guarantor Senior
Indebtedness of such Guarantor.

                    -----------------------------------------------------------
Held in Trusts.
- - -------------- 

          A.   No Payments in Certain Circumstances.  No direct or indirect
               ------------------------------------

time of such payment, there exists a default in the payment of all or any
portion of the obligations on any Designated Guarantor Senior Indebtedness of
such Guarantor, whether at maturity, on account of mandatory redemption or
prepayment, acceleration or otherwise, and such default shall not have been
cured or waived or the benefits of this sentence waived by or on behalf of the
Lenders of such Designated Guarantor Senior Indebtedness.  In addition, during
the continuance of any nonpayment event of default with respect to any
Designated Guarantor Senior Indebtedness pursuant to which the maturity thereof
may be immediately accelerated, and upon receipt by the An-anger of written
notice (the "Guarantor Payment Blockage Notice") from the Lender or Lenders of
             ---------------------------------                                
such Designated Guarantor Senior Indebtedness or the Arranger or agent acting on
behalf of such Designated Guarantor Senior Indebtedness, then, unless and until
such event of default has been cured or waived or has ceased to exist or such
Designated Guarantor Senior Indebtedness has been discharged or paid in full in
cash or the benefits of these provisions have been waived by the Lenders of such
Designated Guarantor Senior Indebtedness, no direct or indirect payment

notice by the Arranger and ending 179 days thereafter.

          Notwithstanding anything herein or in the Loans or Notes to the
contrary, (x) in no event shall a Guarantor Blockage Period extend beyond 179
days from the date the Guarantor Payment Blockage Notice in respect thereof was
given, (y) there shall be a period of at least 181 consecutive days in each 360-
day period when no Guarantor Blockage Period is in effect and (z) not more than
one Guarantor Blockage Period may be commenced with respect to any Guarantor
during any period of 360 consecutive days. No event of default that existed or
was continuing on the date of commencement of any other Guarantor Blockage
Period with respect to the Designated Guarantor Senior Indebtedness initiating
such Guarantor Blockage Period (to the extent the Lender of Designated Guarantor
Senior Indebtedness, or the trustee or agent acting on behalf of such Designated
Guarantor Senior Indebtedness, giving notice commencing such Guarantor Blockage
Period had knowledge of such existing or continuing event of default) may be, or
be made, the basis for the commencement of any other Guarantor Blockage Period
by the Lender or Lenders of such Designated Guarantor Senior Indebtedness or the
Arranger or agent acting on behalf of such Designated Guarantor Senior
Indebtedness, whether or not within a period of 360 consecutive days, unless
such event of default has been cured or waived for a period of not less than 90
consecutive days.

          B.   Payments Held in Trust.  In the event that, notwithstanding the
               ----------------------                                         
foregoing, any payment shall be received by the Arranger or any Lender when such
payment is prohibited by Section 14.02A, such payment shall be held in trust for
the benefit of, and shall be paid over or delivered to, the Lenders of such
Designated Guarantor Senior Indebtedness or their respective representatives, or
to the trustee under any agreement pursuant to which any of such Designated
Guarantor Senior Indebtedness may have been issued, as their respective
interests may appear, but only to the extent that, upon notice from the An-anger
to the Lenders of such Designated Guarantor Senior Indebtedness that such
prohibited payment has been made, the Lenders of such Designated Guarantor
Senior Indebtedness (or their representative or representatives or a trustee)
notify the Arranger in writing of the amounts then due and owing on such
Designated Guarantor Senior Indebtedness, if any, and only the amounts specified
in such notice to the An-anger shall be paid to the Lenders of such Designated
Guarantor Senior Indebtedness.

of such Guarantor shall first be paid in full before the Lenders or the Arranger
on behalf of such Lenders shall be entitled to receive any payment by such
Guarantor of the principal of or interest on the Loans or Notes pursuant to such
Guarantor's Guarantee, or any payment to acquire any of the Loans or Notes for
cash, property or securities, or any distribution with respect to the Loans or

payment or distribution of Permitted Junior Securities), to which the Lenders or
the An-anger on their behalf would be entitled, but for the subordination

                                     -93-

 
a payment by such Guarantor to or on account of such Guarantor Senior
Indebtedness. It is understood that the provisions of this Section 14 are and
are intended solely for the purpose of defining the relative rights of the
Lenders, on the one hand, and the Lenders of Guarantor Senior Indebtedness of
each Guarantor, on the other hand.

          If any payment or distribution to which the Lenders would otherwise
have been entitled but for the provisions of this Section 14 shall have been
applied, pursuant to the provisions of this Section 14, to the payment of all
amounts payable under Guarantor Senior Indebtedness, then and in such case, the
Lenders shall be entitled to receive from the Lenders of such Guarantor Senior
Indebtedness any payments or distributions received by such Lenders of Guarantor
Senior Indebtedness in excess of the amount required to make payment in full, or
provision for payment, of such Guarantor Senior Indebtedness.

          14.05.    Obligations of Guarantors Unconditional.  Nothing contained
                    ---------------------------------------                    
in this Section 14 or elsewhere in this Agreement or in the Loans, Notes or the
Guarantees is intended to or shall impair, as among the Guarantors and the
Lenders, the obligation of each Guarantor, which is absolute and unconditional,
to pay to the Lenders the principal of and interest on the Loans and Notes as
and when the same shall become due and payable in accordance with the terms of
the Guarantee of such Guarantor, or is intended to or shall affect the relative
rights of the Lenders and creditors of any Guarantor other than the Lenders of
Guarantor Senior Indebtedness of such Guarantor, nor shall anything herein or
therein prevent the Lender or the An-anger on their behalf from exercising all
remedies otherwise permitted by applicable law upon default under this
Agreement, subject to the rights, if any, under this Section 14 of the Lenders
of Guarantor Senior Indebtedness in respect of cash, property or securities of
any Guarantor received upon the exercise of any such remedy.

          Without limiting the generality of the foregoing, nothing contained in
this Section 14 shall restrict the right of the Lenders or the Arranger to take
any action to declare the Loans and Notes to be due and payable prior to their
stated maturity pursuant to Section 10 or to pursue any rights or remedies
hereunder; provided, however, that all Guarantor Senior Indebtedness of any
           --------  -------                                               
Guarantor then due and payable shall first be paid in full before the Lenders or
the Arranger are entitled to receive any direct or indirect payment from such
Guarantor of principal of or interest on the Loans and Notes pursuant to such
Guarantor's Guarantee.

          14.06.    Notice to Arranger.  Borrower and each Guarantor shall give
                    ------------------                                         
prompt written notice to the Arranger of any fact known to Borrower or such
Guarantor which would prohibit the making of any payment to or by the Arranger
in respect of the Securities pursuant to the provisions of this Section 14. The
Arranger shall not be charged with knowledge of the existence of any event of
default with respect to any Guarantor Senior Indebtedness or of any other facts
which would prohibit the making of any payment to or by the Arranger unless and
until the An-anger shall have received notice in writing to that effect signed
by an Officer of Borrower or such Guarantor, or by a Lender of Guarantor Senior
Indebtedness or the trustee or agent therefor; and prior to the receipt of any
such written notice, the An-anger shall be entitled to assume that no such facts
exist; provided, however, that if the Arranger shall not have received the
       --------  -------                                                  
notice provided for in this Section 14.06 at least two Business Days prior to
the date upon which by the terms of this Agreement any moneys shall become
payable for any purpose (including, without limitation, the payment of the
principal of or interest on any Loan or Note), then, regardless of anything
herein to the contrary, the An-anger shall have full power and ' authority to
receive any moneys from any Guarantor and to apply the same to the purpose for
which they were received, and shall not be affected by any notice to the
contrary which may be received by it on or after such prior date. Nothing
contained in this Section 14.06 shall limit the right of the Lenders of
Guarantor Senior Indebtedness to recover payments as contemplated by Section
14.03.  The Arranger shall be entitled to rely on the delivery to it of a
written notice by a Person representing himself or itself to be a Lender of any
Guarantor Senior Indebtedness (or a trustee on behalf of, or other
representative of, such Lender) to establish that such notice has been given by
a Lender of such Guarantor Senior Indebtedness or a trustee or representative on
behalf of any such Lender.

          In the event that the Arranger determines in good faith that any
evidence is required with respect to the right of any Person as a Lender of
Guarantor Senior Indebtedness to participate in any payment or distribution
pursuant to this Section 14, the An-anger may request such Person to furnish
evidence to the reasonable satisfaction of the Arranger as to the amount of
Guarantor Senior Indebtedness held by such Person, the extent to which such
Person is entitled to participate in such payment or distribution and any other
facts pertinent to the rights of such 

                                     -94-

 
Person under this Section 14, and if such evidence is not furnished, the
Arranger may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

          14.07.    Reliance on Judicial Order or Certificate of Liquidating
                    --------------------------------------------------------
Agent.  Upon any payment or distribution of assets or securities of a Guarantor
- - -----                                                                          
referred to in this Section 14, the Arranger and the Lenders shall be entitled
to rely upon any order or decree made by any court of competent jurisdiction in
which bankruptcy, dissolution, winding-up, liquidation or reorganization
proceedings are pending, or upon a certificate of the receiver, trustee in
bankruptcy, liquidating trustee, agent or other person making such payment or
distribution, delivered to the Arranger or to the Lenders for the purpose of
ascertaining the Persons entitled to participate in such distribution, the
Lenders of Guarantor Senior Indebtedness of such Guarantor and other
indebtedness of such Guarantor, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Section 14.

          14.08.    Arranger's Relation to Guarantor Senior Indebtedness.  The
                    ----------------------------------------------------      
Arranger shall be entitled to all the rights set forth in this Section 14 with
respect to any Guarantor Senior Indebtedness which may at any time be held by it
in its individual or any other capacity to the same extent as any other Lender
of Guarantor Senior Indebtedness, and nothing in this Agreement shall deprive
the Arranger of any of its rights as such Lender.

          With respect to the Lenders of Guarantor Senior Indebtedness, the
Arranger undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Section 14, and no implied
covenants or obligations with respect to the Lenders of Guarantor Senior
Indebtedness shall be read into this Agreement against the Arranger.  The
Arranger shall not be deemed to owe any fiduciary duty to the Lenders of
Guarantor Senior Indebtedness (except as provided in Section 14.03B).  The
Arranger shall not be liable to any such Lenders if the An-anger shall in good
faith mistakenly pay over or distribute to Lenders or to Borrower or to any
other person cash, property or securities to which any Lenders of Guarantor
Senior Indebtedness shall be entitled by virtue of this Section 14 or otherwise.

          14.09.    Subordination Rights Not Impaired by Acts or Omissions of
                    ---------------------------------------------------------
the Guarantors or Lenders of. Guarantor Senior Indebtedness.  No right of any
- - ------------------------------------------------------------                 
present or future Lenders of any Guarantor Senior Indebtedness to enforce
subordination as provided herein shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of any Guarantor or by any act
or failure to act, in good faith, by any such Lender, or by any noncompliance by
any Guarantor with the terms of this Agreement, regardless of any knowledge
thereof which any such Lender may have or otherwise be charged with. The
provisions of this Section 14 are intended to be for the benefit of, and shall
be enforceable directly by, the Lenders of Guarantor Senior Indebtedness.

          14.10.    Lenders Authorize Arranger To Effectuate Subordination of
                    ---------------------------------------------------------
Guarantee.  Each Lender by its acceptance of Loans and Notes authorizes and
- - ---------                                                                  
expressly directs the Arranger on its behalf to take such action as may be
necessary or appropriate to effectuate the subordination provided in this
Section 14, and appoints the An-anger its Attorney-in-fact for such purposes,
including, in the event of any dissolution, winding-up, liquidation or
reorganization of any Guarantor (whether in bankruptcy, insolvency,
receivership, reorganization or similar proceedings or upon an assignment for
the benefit of creditors or otherwise) tending towards liquidation of the
business and assets of such Guarantor, the filing of a claim for the unpaid
balance of its Loans and Notes in the form required in those proceedings.

          14.11.    This Article Not To Prevent Events of Default.  The failure
                    ---------------------------------------------              
to make a payment on account of principal of or interest on the Securities by
reason of any provision of this Section 14 shall not be construed as preventing
the occurrence of an Event of Default specified in Section 10.

          14.12.    Arranger's Compensation Not Prejudiced.  Nothing in this
                    --------------------------------------                  
Section 14 shall apply to amounts due to the An-anger pursuant to other sections
in this Agreement.

          14.13.    No Waiver of Guarantee Subordination Provisions.  Without in
                    -----------------------------------------------             
any way limiting the generality of Section 14.09, the Lenders of Guarantor
Senior Indebtedness may, at any time and from time to time, without the consent
of or notice to the An-anger or the Lenders, without incurring responsibility to
the Lenders and 

                                     -95-

 
without impairing or releasing the subordination provided in this Section 14 or
the obligations hereunder of the Lenders to the Lenders of Guarantor Senior
Indebtedness, do any one or more of the following: (a) change the manner, place
or terms of payment or extend the time of payment of, or renew or alter,
Guarantor Senior Indebtedness or any instrument evidencing the same or any
agreement under which Guarantor Senior Indebtedness is outstanding or secured;

Guarantor, except under the conditions described in Section 14.02, from making
payments of principal of and interest on the Loans or Notes, or from depositing
with the Arranger any moneys for such payments, or (ii) the application by the
Arranger of any moneys deposited with it for the purpose of making such payments
of principal of and interest on the Loans or Notes, to the Lenders entitled
thereto unless at least two Business Days prior to the date upon which such
payment becomes due and payable, the Arranger shall have received the written
notice provided for in Section 14.02B or in Section 14.06.  A Guarantor shall
give prompt written notice to the Arranger of any dissolution, winding-up,
liquidation or reorganization of such Guarantor.
