(as hereinafter defined) and Borrowers, to provide working capital financing for
Borrowers and to provide funds for other general corporate purposes of
Borrowers; and

         WHEREAS, Borrowers desire to secure all of their Obligations (as
hereinafter defined) under the Loan Documents (as hereinafter defined) by

and lien upon substantially all of their existing and after-acquired personal
and real property; and

         WHEREAS, Borrowers are willing to pledge to Agent, for the benefit of
Agent and Lenders, all of the Stock of their wholly owned Subsidiaries to secure
the Obligations; and

         WHEREAS, each Credit Party has agreed to secure all of the Obligations
by granting to Agent, for the benefit of Agent and Lenders, a security interest
in and lien upon all of their existing and after-acquired personal and real
property; and

         WHEREAS, each Borrower is willing to guaranty all of the Obligations of

                                   SECTION 1.

                           AMOUNTS AND TERMS OF LOANS

         1.1.     Loans. Subject to the terms and conditions of this Agreement
and in reliance upon the representations and warranties of Borrowers and the
other Credit Parties contained herein:

                  (a)      Revolving Loans.

                           (i)      Each Revolving Lender agrees, severally and
not jointly, to make available to Borrowers from time to time until the
Commitment Termination Date its Pro Rata Share of advances (each a "Revolving
Credit Advance") requested by Borrower Representative on behalf of the Borrowers
hereunder. The Pro Rata Share of the Revolving Loan of any Revolving Lender
(including, without duplication, Swing Line Loans) shall not at any time exceed
its separate Revolving Loan Commitment. Revolving Credit Advances may be repaid
and reborrowed; provided, that the amount of any Revolving Credit Advance to be
made at any time shall not exceed Borrowing Availability. Borrowing Availability
may be further reduced by Reserves imposed by Agent in its reasonable credit
judgment. Moreover, the sum of the Revolving Loan and Swing Line Loan
outstanding to any Borrower shall not exceed at any time that Borrower's
separate Borrowing Base. All Revolving Loans shall be repaid in full on the
Commitment Termination Date. Each Borrower shall execute and deliver to each
Revolving Lender a note to evidence the Revolving Loan Commitment of that
Revolving Lender. Each note shall be in the maximum principal amount of the
Revolving Loan Commitment of the applicable Revolving Lender, dated the Closing
Date and substantially in the form of Exhibit 1.1(a)(i) (each as amended,
modified, extended, substituted or replaced from time to time, a "Revolving
Note" and, collectively, the "Revolving Notes"). Other than pursuant to Section
1.1(a)(ii), if at any time the outstanding Revolving Loans (including the Swing
Line Loans) exceed the Borrowing Base or the outstanding balance of the
Revolving Loan of any Borrower (including the Swing Line Loans advanced to that
Borrower) exceeds that Borrower's separate Borrowing Base (any such excess
Revolving Loans are herein referred to collectively as "Overadvances"), Lenders
shall not be obligated to make Revolving Credit Advances, no additional Letters
of Credit shall be issued and, except as provided in Section 1.1(a)(ii) below,
Revolving Loans must be repaid immediately and Letters of Credit cash
collateralized in an amount sufficient to eliminate any Overadvances.
Furthermore, if, at any time, the outstanding balance of the Revolving Loan of
any Borrower (including, without duplication, Swing Line Loans) exceeds that
Borrower's separate Borrowing Base (including, without duplication, Swing Line
Loans), the applicable Borrower shall immediately repay its Revolving Credit
Advances in the amount of such excess (and, if necessary, shall provide cash
collateral for its Letter of Credit Obligations). All Overadvances shall
constitute Index Rate Loans and shall bear interest at the Default Rate.
Revolving Credit Advances which are to be made as Index Rate Loans may be
requested in any amount with one (1) Business Day's prior written notice
required for funding requests equal to or greater than $5,000,000. For funding
requests for such Loans less than $5,000,000, written notice must be provided by
1:00 p.m. (New York time) on the Business Day on which such Revolving Credit
Advance is to be made. All requests for Revolving Credit Advances that are to be
made as LIBOR Loans require three (3) Business Days' prior written notice.
Written notices for funding requests shall be in the form attached as Exhibit
1.1(a)(ii) ("Notice of Revolving Credit Advance"). Each Revolving Credit Advance
to Penhall Leasing shall be in a minimum amount of $250,000. Each Revolving
Credit Advance to Holdings, Penhall and Bob Mack shall be in a minimum amount of
$100,000.

                           (ii)     If Borrower Representative on behalf of
Borrowers requests that Revolving Lenders make, or permit to remain outstanding
any Overadvances, Agent may, in its sole discretion, elect to make, or permit to
remain outstanding such Overadvances; provided, however, that Agent may not
cause Revolving Lenders to make, or permit to remain outstanding, (a) aggregate

                                     - 2 -
<PAGE>

Revolving Loans (including, without duplication, Swing Line Loans) in excess of
the Maximum Amount or (b) Overadvances in an aggregate amount in excess of
$5,000,000. If an Overadvance is made, or permitted to remain outstanding,
pursuant to the preceding sentence, then all Revolving Lenders shall be bound to
make, or permit to remain outstanding such Overadvance based upon their Pro Rata
Shares of the Revolving Loan Commitments in accordance with the terms of this
Agreement. If an Overadvance remains outstanding for more than ninety (90) days
during any one hundred eighty (180) day period, Revolving Loans must be repaid
immediately in an amount sufficient to eliminate all of such Overadvances.
Furthermore, holders of a majority of the Revolving Loan Commitment may
prospectively revoke Agent's ability to make or permit Overadvances by written
notice to Agent. Any Overadvance may be made as a Swing Line Advance.

                  (b)      Omitted.

                  (c)      Swing Line Facility.

                           (i)      Agent shall notify the Swing Line Lender
upon Agent's receipt of any Notice of Revolving Credit Advance. Subject to the
terms and conditions hereof, the Swing Line Lender may, in its discretion, make
available from time to time until the Commitment Termination Date advances
(each, a "Swing Line Advance") in accordance with any such notice. The
provisions of this Section 1.1(c) shall not relieve Revolving Lenders of their
obligations to make Revolving Credit Advances under Section 1.1(a); provided
that if the Swing Line Lender makes a Swing Line Advance pursuant to any such
notice, such Swing Line Advance shall be in lieu of any Revolving Credit Advance
that otherwise may be made by Revolving Lenders pursuant to such notice. Except
as provided in Section 1.1(a)(ii) above, no Swing Line Advance shall be made if
(A) such Swing Line Advance, when added to the other Swing Line Advances then
outstanding, shall exceed the Swing Line Commitment or (B) such Swing Line
Advance shall exceed Borrowing Availability (the lesser of (A) and (B), "Swing
Line Availability"). Moreover, except for Overadvances, the Swing Line Loan
outstanding to any Borrower shall not exceed at any time that Borrower's
separate Borrowing Base less the Revolving Loan outstanding to such Borrower.
Until the Commitment Termination Date, Borrowers may from time to time borrow,
repay and reborrow under this Section 1.1(c). Each Swing Line Advance shall be
made pursuant to a Notice of Revolving Credit Advance delivered by Borrower
Representative on behalf of the applicable Borrower to Agent in accordance with
Section 1.1(a). Unless the Swing Line Lender has received at least one (1)
Business Day's prior written notice from Requisite Lenders instructing it not to
make a Swing Line Advance, the Swing Line Lender shall, notwithstanding the
failure of any condition precedent set forth in Section 7.2, be entitled to fund
that Swing Line Advance, and to have each Revolving Lender make Revolving Credit
Advances in accordance with Section 1.1(c)(iii) or purchase participating
interests in accordance with Section 1.1(c)(iv). Notwithstanding any other
provision of this Agreement or the other Loan Documents, the Swing Line Loan
shall constitute an Index Rate Loan. Borrowers shall repay the aggregate
outstanding principal amount of the Swing Line Loan upon demand therefor by
Agent. The entire unpaid balance of the Swing Line Loan and all other
noncontingent Obligations shall be immediately due and payable in full in
immediately available funds on the Commitment Termination Date if not sooner
paid in full. Each Swing Line Advance shall be in a minimum amount of $250,000.

                           (ii)     Each Borrower shall execute and deliver to
the Swing Line Lender a promissory note to evidence the Swing Line Commitment.
Each note shall be in the principal amount of the Swing Line Commitment of the
Swing Line Lender, dated the Closing Date and substantially in the form of
Exhibit 1.1(c) (each as amended, modified, extended, substituted or replaced
from time to time, a "Swing Line Note" and, collectively the "Swing Line
Notes"). Each Swing Line Note shall represent the obligation of each Borrower to
pay the amount of the Swing Line Commitment or, if less, the aggregate unpaid
principal amount of all Swing Line Advances made to such Borrower together with
interest thereon as prescribed in Section 1.2.

<PAGE>

                           (iii)    The Swing Line Lender, at any time and from
time to time in its sole and absolute discretion (but no less frequently than
weekly), may on behalf of any Borrower (and each Borrower hereby irrevocably
authorizes the Swing Line Lender to so act on its behalf) request each Revolving
Lender (including the Swing Line Lender) to make a Revolving Credit Advance to
each Borrower (which shall be an Index Rate Loan) in an amount equal to that
Revolving Lender's Pro Rata Share of the principal amount of the applicable
Borrower's Swing Line Loan (the "Refunded Swing Line Loan") outstanding on the
date such notice is given. Unless any of the events described in Sections 6.1(f)
and 6.1(g) has occurred (in which event the procedures of Section 1.1(c)(iv)
shall apply) and regardless of whether the conditions precedent set forth in
this Agreement to the making of a Revolving Credit Advance are then satisfied,
each Revolving Lender shall disburse directly to Agent, its Pro Rata Share of a
Revolving Credit Advance on behalf of the Swing Line Lender, prior to 3:00 p.m.
(New York time), in immediately available funds on the Business Day next
succeeding the date that notice is given. The proceeds of those Revolving Credit
Advances shall be immediately paid to the Swing Line Lender and applied to repay
the Refunded Swing Line Loan of the applicable Borrower.

                           (iv)     If, prior to refunding a Swing Line Loan
with a Revolving Credit Advance pursuant to Section 1.1(c)(iii), one of the
events described in Sections 6.1(f) or 6.1(g) has occurred, then, subject to the
provisions of Section 1.1(c)(v) below, each Revolving Lender shall, on the date
such Revolving Credit Advance was to have been made for the benefit of the
applicable Borrower, purchase from the Swing Line Lender an undivided
participation interest in the Swing Line Loan to such Borrower in an amount
equal to its Pro Rata Share (determined with respect to Revolving Loans) of such
Swing Line Loan. Upon request, each Revolving Lender shall promptly transfer to
the Swing Line Lender, in immediately available funds, the amount of its
participation interest.

                           (v)      Each Revolving Lender's obligation to make
Revolving Credit Advances in accordance with Section 1.1(c)(iii) and to purchase
participation interests in accordance with Section 1.1(c)(iv) shall be absolute
and unconditional and shall not be affected by any circumstance, including (A)
any setoff, counterclaim, recoupment, defense or other right that such Revolving
Lender may have against the Swing Line Lender, any Borrower or any other Person
for any reason whatsoever; (B) the occurrence or continuance of any Default or
Event of Default; (C) any inability of any Borrower to satisfy the conditions
precedent to borrowing set forth in this Agreement at any time or (D) any other
circumstance, happening or event whatsoever, whether or not similar to any of
the foregoing. Swing Line Lender shall be entitled to recover, on demand, from
each Revolving Lender the amounts required pursuant to Sections 1.1.(c)(iii) or
1.1(c)(iv), as the case may be. If any Revolving Lender does not make available
such amounts to Agent or the Swing Line Lender, as applicable, the Swing Line
Lender shall be entitled to recover, on demand, such amount on demand from such
Revolving Lender, together with interest thereon for each day from the date of
non-payment until such amount is paid in full at the Federal Funds Rate for the
first two (2) Business Days and at the Index Rate thereafter.

                  (d)      Letters of Credit. The Revolving Loan Commitment may,
in addition to advances under the Revolving Loan, be utilized, upon the request
of Borrower Representative on behalf of the applicable Borrower, for the
issuance of Letters of Credit. Immediately upon the issuance by an L/C Issuer of
a Letter of Credit, and without further action on the part of Agent or any of
the Lenders, each Revolving Lender shall be deemed to have purchased from such
L/C Issuer a participation in such Letter of Credit (or in its obligation under
a risk participation agreement with respect thereto) equal to such Revolving
Lender's Pro Rata Share of the aggregate amount available to be drawn under such
Letter of Credit.

                           (i)      Maximum Amount. The aggregate amount of
Letter of Credit Obligations with respect to all Letters of Credit outstanding
at any time shall not exceed $25,000,000 ("L/C Sublimit").

                                     - 4 -
<PAGE>

                           (ii)     Reimbursement. Borrowers shall be
irrevocably and unconditionally obligated forthwith without presentment, demand,
protest or other formalities of any kind (including for purposes of Section 10),
to reimburse any L/C Issuer on demand in immediately available funds for any
amounts paid by such L/C Issuer with respect to a Letter of Credit, including
all reimbursement payments, Fees, Charges, costs and expenses paid by such L/C
Issuer. Borrowers hereby authorize and direct Agent, at Agent's option, to debit
Borrowers' account (by increasing the outstanding principal balance of the
Revolving Credit Advances) in the amount of any payment made by an L/C Issuer
with respect to any Letter of Credit. All amounts paid by an L/C Issuer with
respect to any Letter of Credit that are not immediately repaid by Borrowers
with the proceeds of a Revolving Credit Advance or otherwise shall bear interest
at the interest rate applicable to Revolving Loans which are Index Rate Loans
plus, at the election of Agent or Requisite Lenders, an additional two percent
(2.00%) per annum. Each Revolving Lender agrees to fund its Pro Rata Share of
any Revolving Loan made pursuant to this Section 1.1(d)(ii). In the event Agent
elects not to debit Borrowers' account and Borrowers fail to reimburse the L/C
Issuer in full on the date of any payment in respect of a Letter of Credit,
Agent shall promptly notify each Revolving Lender of the amount of such
unreimbursed payment and the accrued interest thereon and each Revolving Lender,
on the next Business Day prior to 3:00 p.m. (New York time), shall deliver to
Agent an amount equal to its Pro Rata Share thereof in same day funds. Each
Revolving Lender hereby absolutely and unconditionally agrees to pay to the L/C
Issuer upon demand by the L/C Issuer such Revolving Lender's Pro Rata Share of
each payment made by the L/C Issuer in respect of a Letter of Credit and not
immediately reimbursed by Borrowers or satisfied through a debit of Borrowers'
account. Each Revolving Lender acknowledges and agrees that its obligations
pursuant to this subsection in respect of Letters of Credit are absolute and
unconditional and shall not be affected by any circumstance whatsoever,
including setoff, counterclaim, the occurrence and continuance of a Default or
an Event of Default or any failure by Borrowers to satisfy any of the conditions
set forth in Section 7.2. If any Revolving Lender fails to make available to the
L/C Issuer the amount of such Revolving Lender's Pro Rata Share of any payments
made by the L/C Issuer in respect of a Letter of Credit as provided in this
Section 1.1(d)(ii), the L/C Issuer shall be entitled to recover such amount on
demand from such Revolving Lender together with interest at the Index Rate.

                           (iii)    Request for Letters of Credit. Borrower
Representative shall give Agent at least three (3) Business Days' prior written
notice specifying the date a Letter of Credit is requested to be issued, the
amount and the name and address of the beneficiary, a description of the
transactions proposed to be supported thereby and the name of the Borrower for
whose account such Letter of Credit is to be issued. If Agent informs Borrower
Representative that the L/C Issuer cannot issue the requested Letter of Credit
directly, such Borrower Representative may request that L/C Issuer arrange for
the issuance of the requested Letter of Credit under a risk participation
agreement with another financial institution reasonably acceptable to Agent, L/C
Issuer and Borrower Representative. The issuance of any Letter of Credit under
this Agreement shall be subject to the conditions that the Letter of Credit (i)
supports a transaction entered into in the ordinary course of business of
Borrowers and (ii) is in a form, is for an amount and contains such terms and
conditions as are reasonably satisfactory to the L/C Issuer and, in the case of
standby letters of credit, Agent. The initial notice requesting the issuance of
a Letter of Credit shall be accompanied by the form of the Letter of Credit and
the Master Standby Agreement or Master Documentary Agreement, as applicable, and
an application for a letter of credit, if any, then required by the L/C Issuer
completed in a manner satisfactory to such L/C Issuer. If any provision of any
application or reimbursement agreement is inconsistent with the terms of this
Agreement, then the provisions of this Agreement, to the extent of such
inconsistency, shall control.

                           (iv)     Expiration Dates of Letters of Credit. The
expiration date of each Letter of Credit shall be on a date which is not later
than the earlier of (a) one year from its date of issuance or (b) the thirtieth
(30th) day prior to the date set forth in clause (a) of the definition of the
term Commitment Termination Date. Notwithstanding the foregoing, a Letter of
Credit may provide for

                                     - 5 -
<PAGE>

automatic extensions of its expiration date for one (1) or more successive one
(1) year periods provided that the L/C Issuer has the right to terminate such
Letter of Credit on each such annual expiration date and no renewal term may
extend the term of the Letter of Credit to a date that is later than the
thirtieth (30th) day prior to the date set forth in clause (a) of the definition
of the term Commitment Termination Date. The L/C Issuer may elect not to renew
any such Letter of Credit and, upon direction by Agent or Requisite Lenders,
shall not renew any such Letter of Credit at any time during the continuance of
an Event of Default, provided that, in the case of a direction by Agent or
Requisite Lenders, the L/C Issuer receives such directions prior to the date
notice of non-renewal is required to be given by the L/C Issuer and the L/C
Issuer has had a reasonable period of time to act on such notice.

                           (v)      Obligations Absolute. The obligation of
Borrowers to reimburse the L/C Issuer, Agent and Lenders for payments made in
respect of Letters of Credit issued by the L/C Issuer shall be unconditional and
irrevocable and shall be paid under all circumstances strictly in accordance
with the terms of this Agreement, including the following circumstances: (a) any
lack of validity or enforceability of any Letter of Credit; (b) any amendment or
waiver of or any consent or departure from all or any of the provisions of any
Letter of Credit or any Loan Document; (c) the existence of any claim, set-off,
defense or other right which Borrowers, any of their Subsidiaries or Affiliates
or any other Person may at any time have against any beneficiary of any Letter
of Credit, Agent, any L/C Issuer, any Lender or any other Person, whether in
connection with this Agreement, any other Loan Document or any other related or
unrelated agreements or transactions; (d) any draft or other document presented
under any Letter of Credit proving to be forged, fraudulent, invalid or
insufficient in any respect or any statement therein being untrue or inaccurate
in any respect; (e) payment under any Letter of Credit against presentation of a
draft or other document that does not substantially comply with the terms of
such Letter of Credit; or (f) any other act or omission to act or delay of any
kind of any L/C Issuer, Agent, any Lender or any other Person or any other event
or circumstance whatsoever that might, but for the provisions of this Section
1.1(d)(v), constitute a legal or equitable discharge of Borrowers' obligations
hereunder.

                           (vi)     Obligations of L/C Issuers. Each L/C Issuer
(other than GE Capital) hereby agrees that it will not issue a Letter of Credit
hereunder until it has provided Agent with written notice specifying the amount
and intended issuance date of such Letter of Credit and Agent has returned a
written acknowledgment of such notice to L/C Issuer. Each L/C Issuer (other than
GE Capital) further agrees to provide to Agent: (a) a copy of each Letter of
Credit issued by such L/C Issuer promptly after its issuance; (b) a weekly
report summarizing available amounts under Letters of Credit issued by such L/C
Issuer, the dates and amounts of any draws under such Letters of Credit, the
effective date of any increase or decrease in the face amount of any Letters of
Credit during such week and the amount of any unreimbursed draws under such
Letters of Credit; and (c) such additional information reasonably requested by
Agent from time to time with respect to the Letters of Credit issued by such L/C
Issuer. Without limiting the generality of the foregoing, it is expressly
understood and agreed by Borrowers that the absolute and unconditional
obligation of Borrowers to Agent and Lenders hereunder to reimburse payments
made under a Letter of Credit will not be excused by the gross negligence or
willful misconduct of the L/C Issuer. However, the foregoing shall not be
construed to excuse an L/C Issuer from liability to Borrowers to the extent of
any direct damages (as opposed to consequential damages, with Borrowers hereby
waiving all claims for any consequential damages to the extent permitted by
applicable law) suffered by Borrowers that are not subject to indemnification
under the Master Standby Agreement or the Master Documentary Agreement.

                  (e)      Funding Authorization. The proceeds of all Loans made
pursuant to this Agreement subsequent to the Closing Date are to be funded by
Agent by wire transfer to the account designated by Borrower Representative
below (the "Disbursement Account"):

                  Bank:         Bank of America
                  ABA No.:      121000358
                  Bank Address: 675 Anton Blvd, Second floor, Costa Mesa, 92626
                  Account No.:  1456300539
                  Reference:    Penhall International - Concentration Account

Borrower Representative shall provide Agent with written notice of any change in
the foregoing instructions at least three (3) Business Days before the desired
effective date of such change.

         1.2.     Interest and Applicable Margins.

                  (a)      Borrowers shall pay interest to Agent, for the
ratable benefit of Lenders, in accordance with the various Loans being made by
each Lender, in arrears on each applicable Interest Payment Date, at the
following rates: (i) with respect to the Revolving Credit Advances which are
designated as Index Rate Loans (and for all other Obligations not otherwise set
forth below), the Index Rate plus the Applicable Revolver Index Margin per annum
or, with respect to Revolving Credit Advances which are designated as LIBOR
Loans, at the election of Borrower Representative, the applicable LIBOR Rate
plus the Applicable Revolver LIBOR Margin per annum; and (ii) with respect to
the Swing Line Loan, the Index Rate plus the Applicable Revolver Index Margin
per annum.

         The Applicable Margins are as follows:

                 Applicable Revolver Index Margin             2.0%

                 Applicable Revolver LIBOR Margin             3.5%

                 Applicable L/C Margin                        3.5%

                  (b)      If any payment on any Loan becomes due and payable on
a day other than a Business Day, the maturity thereof will be extended to the
next succeeding Business Day (except as set forth in the definition of LIBOR
Period) and, with respect to payments of principal, interest thereon shall be
payable at the then applicable rate during such extension.

                  (c)      All computations of Fees calculated on a per annum
basis and interest shall be made by Agent on the basis of a 360-day year, in
each case for the actual number of days occurring in the period for which such
Fees and interest are payable. The Index Rate is a floating rate determined for
each day. Each determination by Agent of an interest rate and Fees hereunder
shall be final, binding and conclusive on Borrowers, absent manifest error.

                  (d)      So long as an Event of Default has occurred and is
continuing under Section 6.1(a), (f) or (g) and without notice of any kind, or
so long as any other Event of Default has occurred and is continuing and at the
election of Agent (or upon the written request of Requisite Lenders) confirmed
by written notice from Agent to Borrower Representative, the interest rates
applicable to the Loans and the Letter of Credit Fee shall be increased by up to
two percentage points (2%) per annum above the rates of interest or the rate of
such Fee otherwise applicable hereunder ("Default Rate"), and all outstanding
Obligations shall bear interest at the Default Rate applicable to such
Obligations. Interest and Letter of Credit Fees at the Default Rate shall accrue
from the initial date of such Event of Default until

                                      - 7 -
<PAGE>

that Event of Default is cured or waived and shall be payable upon demand, but
in any event, shall be payable on the next regularly scheduled payment date set
forth herein for such Obligation.

                  (e)      Borrower Representative shall have the option to (i)
request that any Revolving Credit Advance be made as a LIBOR Loan, (ii) convert
at any time all or any part of outstanding Loans (other than the Swing Line
Loan) from Index Rate Loans to LIBOR Loans, (iii) convert any LIBOR Loan to an
Index Rate Loan, subject to payment of the LIBOR Breakage Fee in accordance with
Section 1.3(e) if such conversion is made prior to the expiration of the LIBOR
Period applicable thereto, or (iv) continue all or any portion of any Loan
(other than the Swing Line Loan) as a LIBOR Loan upon the expiration of the
applicable LIBOR Period and the succeeding LIBOR Period of that continued Loan
shall commence on the first day after the last day of the LIBOR Period of the
Loan to be continued. Any Loan or group of Loans having the same proposed LIBOR
Period to be made or continued as, or converted into, a LIBOR Loan must be in a
minimum amount of $1,000,000 and integral multiples of $100,000 in excess of
such amount. Any such election must be made by 1:00 p.m. (New York time) on the
third Business Day prior to (1) the date of any proposed Revolving Credit
Advance which is to bear interest at the LIBOR Rate, (2) the end of each LIBOR
Period with respect to any LIBOR Loans to be continued as such, or (3) the date
on which Borrower Representative wishes to convert any Index Rate Loan (other
than the Swing Line Loan) to a LIBOR Loan for a LIBOR Period designated by
Borrower Representative in such election. If no election is received with
respect to an existing LIBOR Loan by 1:00 p.m. (New York time) on the third
Business Day prior to the end of the LIBOR Period with respect thereto, that
LIBOR Loan shall be converted to an Index Rate Loan at the end of its LIBOR
Period. Borrower Representative must make such election by notice to Agent in
writing, by fax or overnight courier. In the case of any conversion or
continuation, such election must be made pursuant to a written notice (a "Notice
of Conversion/Continuation") in the form of Exhibit 1.2(e). No Loan shall be
made, converted into or continued as a LIBOR Loan, if an Event of Default has
occurred and is continuing and Agent or Requisite Lenders have determined not to
make or continue any Loan as a LIBOR Loan as a result thereof.

                  (f)      Notwithstanding anything to the contrary set forth in
this Section 1.2, if a court of competent jurisdiction determines in a final
order that any rate of interest payable hereunder exceeds the highest rate of
interest permissible under law (the "Maximum Lawful Rate"), then so long as the
Maximum Lawful Rate would be so exceeded, such rate of interest payable
hereunder shall be equal to the Maximum Lawful Rate; provided, however, that if
at any time thereafter such rate of interest payable hereunder is less than the
Maximum Lawful Rate, Borrowers shall continue to pay interest hereunder at the
Maximum Lawful Rate until such time as the total interest received by Agent, on
behalf of Lenders, is equal to the total interest that would have been received
had such interest rate payable hereunder been (but for the operation of this
paragraph) the interest rate payable since the Closing Date as otherwise
provided in this Agreement. Thereafter, such interest hereunder shall be paid at
the rate(s) of interest and in the manner provided in Sections 1.2(a) through
(e), unless and until such rate of interest again exceeds the Maximum Lawful
Rate, and at that time this paragraph shall again apply. In no event shall the
total interest received by any Lender pursuant to the terms hereof exceed the
amount that such Lender could lawfully have received had the interest due
hereunder been calculated for the full term hereof at the Maximum Lawful Rate.
If the Maximum Lawful Rate is calculated pursuant to this paragraph, such
interest shall be calculated at a daily rate equal to the Maximum Lawful Rate
divided by the number of days in the year in which such calculation is made. If,
notwithstanding the provisions of this Section 1.2(f), a court of competent
jurisdiction shall determine by a final, non-appealable order that a Lender has
received interest hereunder in excess of the Maximum Lawful Rate, Agent shall,
to the extent permitted by applicable law, promptly apply such excess as
specified in Section 1.5(e) and thereafter shall refund any excess to Borrowers
or as such court of competent jurisdiction may otherwise order.

application and related documentation under which such Letter of Credit is

Borrower in making any borrowing of, conversion into or continuation of any
LIBOR Loan following Borrower Representative's delivery to Agent of any LIBOR
Loan request in respect thereof or (ii) any payment of a LIBOR Loan on any day
that is not the last day of the LIBOR Period applicable thereto (regardless of
the source of such prepayment and whether voluntary, by acceleration or
otherwise), Borrowers shall pay Agent, for the benefit of all Lenders that
funded or were prepared to fund any such LIBOR Loan, the LIBOR Breakage Fee.

work-out or action to enforce any Loan Document or to collect any payments due
from Borrowers or any other Credit Party, Borrowers agree to promptly pay all
fees, charges, costs and expenses incurred by Lenders for one (1) counsel acting

Borrowers shall receive credit on the day of receipt for funds received by Agent
by 2:00 p.m. (New York time). In the absence of timely receipt, such funds shall
be deemed to have been paid on the next Business Day. Whenever any payment to be
made hereunder shall be stated to be due on a day that is not a Business Day,
the payment may be made on the next succeeding Business Day and such extension
of time shall be included in the computation of the amount of interest and Fees
due hereunder.

         Borrowers hereby authorize Lenders to make Revolving Credit Advances or
Swing Line Advances, on the basis of their Pro Rata Shares, for the payment of
interest, Fees and expenses, Letter of Credit reimbursement obligations and any
amounts required to be deposited with respect to outstanding Letter of Credit
Obligations pursuant to Sections 1.5(g) or 6.3.

         1.5.     Prepayments.

                  (a)      Voluntary Prepayments of Loans. At any time,
Borrowers may prepay the Loans, in whole or in part, without premium or penalty
subject to the payment of LIBOR Breakage Fees, if applicable.

                                     - 10 -
<PAGE>

                  (b)      Prepayments under Sections 1.5(c) and 1.5(f) shall be
accompanied by accrued and unpaid interest on the amount prepaid.

                  (c)      Prepayments from Asset Dispositions. Except as
otherwise provided in Section 1.5(f) hereof, immediately upon receipt of any Net
Proceeds in excess of $250,000 for any single transaction or series of related
transactions during any Fiscal Year, Borrowers shall repay the Revolving Credit
Advances (without reduction of the Revolving Loan Commitment) by an amount equal
to the amount of such excess Net Proceeds. Borrowers or their Subsidiaries may
reinvest all remaining Net Proceeds of such Asset Disposition (other than from a
Permitted Sale-Leaseback), within one hundred and eighty (180) days, in
productive replacement assets of a kind then used or usable in the business of
Borrowers. If Borrowers do not intend to so reinvest such Net Proceeds or if the
period set forth in the immediately preceding sentence expires without Borrowers
having reinvested such Net Proceeds, Borrowers shall prepay the Revolving Credit
Advances (without reduction of the Revolving Loan Commitment) in an amount equal
to such remaining Net Proceeds of such Asset Disposition. The payments shall be
applied in accordance with Section 1.5(e).

                  (d)      Omitted.

                  (e)      Application of Proceeds. With respect to any
prepayments made by any Borrower pursuant to Section 1.5(a), such prepayments
shall be applied as follows: first, to reduce the outstanding principal balance
of the Swing Line Loan outstanding to that Borrower until the same has been
repaid in full; second, to the Revolving Credit Advances outstanding to that
Borrower until the same has been repaid in full but not as a permanent reduction
of the Revolving Loan Commitment; third, to the principal balances of the Swing
Line Loan outstanding to each other Borrower, pro rata, until the same have been
repaid in full; and fourth, to the principal balance of the Revolving Credit
Advances made to each other Borrower, pro rata, until the same has been repaid
in full but not as a permanent reduction of the Revolving Loan Commitment.
Considering each type of Loan being prepaid separately, any such prepayment
shall be applied first to Index Rate Loans of the type required to be prepaid
before application to LIBOR Loans of the type required to be prepaid, in each
case in a manner which minimizes any resulting LIBOR Breakage Fee.

                  (f)      Application of Prepayments from Insurance Proceeds.
Prepayments from insurance in accordance with Section 2.2 or condemnation
proceeds shall be applied as follows: insurance proceeds from casualties or
losses to cash, Parts and Supplies, Equipment, Fixtures and Real Estate shall be
applied first, to the Swing Line Loans and second to the Revolving Credit
Advances of the Borrower that incurred such casualties with losses and then to
the Swing Line Loans and last to the Revolving Credit Advances of the other
Borrowers (pro rata in each case). Neither the Revolving Loan Commitment nor the
Swing Line Loan Commitment shall be permanently reduced by the amount of any
such prepayments.

                  (g)      Letter of Credit Obligations. In the event any
Letters of Credit are outstanding at the time that the Revolving Loan Commitment
is terminated, Borrowers shall (1) deposit with Agent for the benefit of all
Revolving Lenders cash in an amount equal to 105% of the aggregate outstanding
Letter of Credit Obligations to be available to Agent to reimburse payments of
drafts drawn under such Letters of Credit and pay any Fees and expenses related
thereto and (2) prepay the fee payable under Section 1.3(d) with respect to such
Letters of Credit for the full remaining terms of such Letters of Credit. Upon
termination of any such Letter of Credit, the unearned portion of such prepaid
fee attributable to such Letter of Credit shall be refunded to Borrowers.

         1.6.     Maturity. All of the Obligations shall become due and payable
as otherwise set forth herein, but in any event all of the remaining Obligations
shall become due and payable upon termination

                                     - 11 -
<PAGE>

of this Agreement. Until all Obligations have been fully paid and satisfied
(other than contingent indemnification obligations to the extent no unsatisfied
claim has been asserted), the Revolving Loan Commitment has been terminated and
all Letters of Credit have been terminated or otherwise secured to the
satisfaction of Agent, Agent shall be entitled to retain the security interests
in the Collateral granted under the Collateral Documents and the ability to
exercise all rights and remedies available to them under the Loan Documents and
applicable laws. Notwithstanding anything contained in this Agreement to the
contrary, upon any termination of the Revolving Loan Commitment, all of the
Obligations shall be due and payable.

         1.7.     Eligible Accounts. All of the Accounts owned by any Borrower
and reflected in the most recent Borrowing Base Certificate delivered by such
Borrower to Agent shall be "Eligible Accounts" for purposes of this Agreement,
except any Account to which any of the exclusionary criteria set forth below

if necessary or desirable, has complied with respect to such obligation with the

                  (a)      that is not owned by such Borrower free and clear of
all Liens and rights of any other Person, except the Liens in favor of Agent, on
behalf of itself and Lenders and Permitted Encumbrances of the type described in
clauses (a), (d), (e) (g), (h) or (j) of the definition of such term;

                  (b)      as to which Agent has not received a loan policy of

discretion (provided such endorsements are available in the jurisdiction where

                  (c)      as to which Agent has not received an environmental

                  (f)      that is not covered by casualty insurance reasonably
acceptable to Agent.

         1.9.     Loan Accounts. Agent shall maintain a loan account (the "Loan
Account") on its books to record: all Advances, all payments made by Borrowers,
and all other debits and credits as provided in

                                     - 18 -
<PAGE>

this Agreement with respect to the Loans or any other Obligations. All entries
in the Loan Account shall be made in accordance with Agent's customary
accounting practices as in effect from time to time. The balance in the Loan
Account, as recorded on Agent's most recent printout or other written statement,
shall, absent manifest error, be presumptive evidence of the amounts due and
owing to Agent and Lenders by Borrowers; provided that any failure to so record
or any error in so recording shall not limit or otherwise affect any Borrower's
duty to pay the Obligations. Agent shall render to Borrower Representative a
monthly accounting of transactions with respect to the Loans setting forth the
balance of the Loan Account as to each Borrower for the immediately preceding
month. Unless Borrower Representative notifies Agent in writing of any objection
to any such accounting (specifically describing the basis for such objection),
within forty-five (45) days after the date thereof, each and every such
accounting shall, absent manifest error, be deemed final, binding and conclusive
on Borrowers in all respects as to all matters reflected therein. Only those
items expressly objected to in such notice shall be deemed to be disputed by
Borrowers. Notwithstanding any provision herein contained to the contrary, any
Lender may elect (which election may be revoked) to dispense with the issuance
of Notes to that Lender and may rely on the Loan Account as evidence of the
amount of Obligations from time to time owing to it.

         1.10.    Yield Protection; Illegality.

                  (a)      Capital Adequacy and Other Adjustments. In the event
that any Lender shall have determined that the adoption after the date hereof of
any law, treaty, governmental (or quasi-governmental) rule, regulation,
guideline or order regarding capital adequacy, reserve requirements or similar
requirements or compliance by any Lender or any corporation controlling such
Lender with any request or directive regarding capital adequacy, reserve
requirements or similar requirements (whether or not having the force of law and
whether or not failure to comply therewith would be unlawful) from any central
bank or governmental agency or body having jurisdiction does or shall have the
effect of increasing the amount of capital, reserves or other funds required to
be maintained by such Lender or any corporation controlling such Lender and
thereby reducing the rate of return on such Lender's or such corporation's
capital as a consequence of its obligations hereunder, then Borrowers shall from
time to time within fifteen (15) days after notice and demand from such Lender
(together with the certificate referred to in the next sentence and with a copy
to Agent) pay to Agent, for the account of such Lender, additional amounts
sufficient to compensate such Lender for such reduction. A certificate as to the
amount of such cost and showing the basis of the computation of such cost
submitted by such Lender to Borrower Representative and Agent shall, absent
manifest error, be final, conclusive and binding for all purposes.

                  (b)      Increased LIBOR Funding Costs; Illegality.
Notwithstanding anything to the contrary contained herein, if the introduction
of or any change in any law, rule, regulation, treaty or directive (or any
change in the interpretation thereof) shall make it unlawful, or any central
bank or other Governmental Authority shall assert that it is unlawful, for any
Lender to agree to make or to make or to continue to fund or maintain any LIBOR
Loan, then, unless that Lender is able to make or to continue to fund or to
maintain such LIBOR Loan at another branch or office of that Lender without, in
that Lender's opinion, adversely affecting it or its Loans or the income
obtained therefrom, on notice thereof and demand therefor by such Lender to
Borrower Representative through Agent, (i) the obligation of such Lender to
agree to make or to make or to continue to fund or maintain LIBOR Loans shall
terminate and (ii) each Borrower shall forthwith prepay in full all outstanding
LIBOR Loans owing by such Borrower to such Lender, together with interest
accrued thereon, unless Borrower Representative on behalf of such Borrower,
within five (5) Business Days after the delivery of such notice and demand,
converts all LIBOR Loans into Index Rate Loans. If, after the date hereof, the
introduction of, change in or interpretation of any law, rule, regulation,
treaty or directive would impose or increase reserve requirements (other than as
taken into account in the definition of LIBOR) or otherwise increase the cost

                                     - 19 -
<PAGE>

to any Lender of making or maintaining a LIBOR Loan, then Borrowers shall from
time to time within fifteen (15) days after notice and demand from Agent to
Borrower Representative (together with the certificate referred to in the next
sentence) pay to Agent, for the account of all such affected Lenders, additional
amounts sufficient to compensate such Lenders for such increased cost. A
certificate as to the amount of such cost and showing the basis of the
computation of such cost submitted by Agent on behalf of all such affected
Lenders to Borrower Representative shall, absent manifest error, be final,
conclusive and binding for all purposes.

         1.11.    Taxes.

                  (a)      No Deductions. Subject to the immediately succeeding
sentence, any and all payments or reimbursements made hereunder (including any
payments made pursuant to Section 10) or under the Notes or other Loan Documents
shall be made free and clear of and without deduction for any and all Charges,
taxes, levies, imposts, deductions or withholdings, and all liabilities with
respect thereto of any nature whatsoever imposed by any taxing authority,
excluding such taxes to the extent imposed on Agent's or a Lender's net income
by the jurisdiction in which Agent or such Lender is organized (such
non-excluded items being referred to herein as "Taxes"). Subject to Section
1.11(c), if any Borrower shall be required by law to deduct any such Taxes from
or in respect of any sum payable hereunder or under any other Loan Document to
any Lender or Agent, then the sum payable hereunder shall be increased as may be
necessary so that, after making all required deductions, such Lender or Agent
receives an amount equal to the sum it would have received had no such
deductions been made. All required deductions shall be complied with and paid
over to the relevant taxing authority or other Governmental Authority in
accordance with applicable law.

                  (b)      Changes in Tax Laws. In the event that, subsequent to
the Closing Date, (1) any changes in any existing law, regulation, treaty or
directive or in the interpretation or application thereof, (2) any new law,
regulation, treaty or directive enacted or any interpretation or application
thereof, or (3) compliance by Agent or any Lender with any request or directive
(whether or not having the force of law) from any Governmental Authority:

                           (i)      does or shall subject Agent or any Lender to
any Tax of any kind whatsoever with respect to this Agreement, the other Loan
Documents or any Loans made or Letters of Credit issued hereunder, or change the
basis of taxation of payments to Agent or such Lender of principal, fees,
interest or any other amount payable hereunder (except for net income taxes, or
franchise taxes imposed in lieu of net income taxes, imposed generally by
federal, state or local taxing authorities with respect to interest or
commitment Fees or other Fees payable hereunder or changes in the rate of tax on
the overall net income of Agent or such Lender); or

                           (ii)     does or shall impose on Agent or any Lender
any other condition or increased cost in connection with the transactions
contemplated hereby or participations herein;

and the result of any of the foregoing is to increase the cost to Agent or any
such Lender of issuing any Letter of Credit or making or continuing any Loan
hereunder, as the case may be, or to reduce any amount receivable hereunder or
under any other Loan Document, then, in any such case, Borrowers shall promptly
pay to Agent or such Lender, upon its demand, any additional amounts necessary
to compensate Agent or such Lender, on an after-tax basis, for such additional
cost or reduced amount receivable, as determined by Agent or such Lender with
respect to this Agreement or the other Loan Documents. Agent and Lenders shall
use their best efforts to avoid or reduce such Taxes by taking any appropriate
action (including assigning their rights hereunder to a related entity or a
different office) which, as determined at such Agent or Lender's sole
discretion, would not be otherwise disadvantageous to such Agent or Lender. If
Agent or such Lender becomes entitled to claim any additional amounts pursuant
to this Section

                                     - 20 -
<PAGE>

1.11(b), it shall promptly notify Borrower Representative of the event by reason
of which Agent or such Lender has become so entitled. A certificate as to any
additional amounts payable pursuant to the foregoing sentence submitted by Agent
or such Lender to Borrower Representative (with a copy to Agent) shall, absent
manifest error, be final, conclusive and binding for all purposes.

                  (c)      Foreign Lenders. Prior to becoming a Lender under
this Agreement and on or before a previously delivered Certificate of Exemption
(as defined below) expires or becomes inapplicable or obsolete, other than by
reason of a change in the applicable rules as in effect at the time a Lender
becomes a Lender under this Agreement, each Lender organized under the laws of a
jurisdiction outside the United States (a "Foreign Lender") shall provide to
Borrower Representative and Agent a properly completed and executed IRS Form
W-8BEN or Form W-8ECI or other applicable form, certificate or document
prescribed by the IRS of the United States certifying as to such Foreign
Lender's entitlement to an exemption from a reduction in United States federal
withholding tax under the applicable rules as in effect at the time the Lender
becomes a Lender under this Agreement with respect to payments to be made to
such Foreign Lender under this Agreement and under the Notes (a "Certificate of
Exemption"). Notwithstanding anything herein to the contrary, if a Foreign
Lender is unable to provide or does not provide a Certificate of Exemption to
Borrower Representative and Agent claiming an exemption from United States
withholding tax within the time periods set forth in the preceding sentence,
Borrowers shall withhold Taxes from payments to such Foreign Lender at the
applicable statutory and treaty rates (taking into account such Foreign Lender's
compliance with applicable certification requirements), and Borrowers shall not
be required to pay any additional amounts as a result of such withholding,
provided that all such withholding shall cease (or be reduced to the applicable
treaty rate) upon delivery by such Foreign Lender of a Certificate of Exemption
to Borrower Representative and Agent.

                  (d)      In addition, the Borrowers agree to pay any current
or future stamp or documentary taxes or any other excise or property taxes,
charges, assessments or similar levies that arise from any payment made
hereunder or from the execution, delivery or registration of, or otherwise with
respect to, this Agreement, the other Loan Documents or any Loans made or
Letters of Credit issued hereunder ("Other Taxes").

                  (e)      The Borrowers shall indemnify Agent and each Lender
for the full amount of Taxes and Other Taxes paid by Agent or such Lender, as
the case may be, and any liability (including penalties, interest and expenses
other than penalties, interest and expenses resulting from the Lender's gross
negligence) arising therefrom or with respect thereto, whether or not such Taxes
or Other Taxes were correctly or legally asserted by the relevant taxing
authority or other Governmental Authority. Such indemnification shall be made
within 30 days after the date Agent or any Lender, as the case may be, makes
written demand therefor. Notwithstanding the foregoing, the Borrowers shall not
be required to provide any indemnity pursuant to the preceding sentence with
respect to taxes, deductions or withholdings (and any liability relating
thereto) for which the Borrowers would have no obligation to increase the sum
payable hereunder (or pay additional amounts) pursuant to Section 1.11(a) and
Section 1.11(c). If Lender or Agent, as the case may be, determines that it is
entitled to receive a refund or credit of such Tax or Other tax, as to which
Borrower has made an additional payment under Section 1.11(a) or if Lender or
Agent has been indemnified pursuant to this Section 1.1.(e), Lender or Agent
shall promptly notify such Borrower of the availability of such refund or
credit. Lender or Agent, as the case may be, shall apply for such refund or
credit within 30 days after receipt of instruction from Borrower to apply for
such refund and in the case of any application for refund or credit made by a
Borrower, Lender shall deliver to such Borrower such certificates, forms or
other documentation as may be reasonably necessary to assist such Borrower in
such application. If any Lender or Agent receives a refund or credit with
respect to any Tax or Other Tax as to which Borrower has made an additional
payment under Section 1.1(a) or if Lender or Agent has been indemnified pursuant
to this Section 1.11(e), Lender or Agent shall

                                     - 21 -
<PAGE>

promptly notify Borrower and shall, within 30 days of receipt of such refund or
the benefit of such credit, repay the amount of such refund or the benefit of
such credit to such Borrower, plus any interest received with respect thereto,
net of all reasonable out-of-pocket expenses of Agent or such Lender.

                  (f)      Within thirty (30) days after the date of any payment
of Taxes or Other Taxes described in Section 1.11(d) above withheld by a
Borrower in respect of any payment to Agent or any Lender, the Borrower shall
furnish to Agent, at its address referred to on the signature pages hereof, the
original or a certified copy of any available receipt evidencing payment
thereof.

         1.12.    Omitted.

         1.13.    Borrower Representative. Each Borrower hereby designates
Penhall (the "Borrower Representative") as its representative and agent on its
behalf for the purposes of issuing Notices of Revolving Credit Advances and
Notices of Conversion/Continuation, giving instructions with respect to the
disbursement of the proceeds of the Loans, selecting interest rate options,
requesting Letters of Credit, giving and receiving all other notices and
consents hereunder or under any of the other Loan Documents and taking all other
actions (including in respect of compliance with covenants) on behalf of any
Borrower or Borrowers under the Loan Documents. Borrower Representative hereby
accepts such appointment. Agent and each Lender may regard any notice or other
communication pursuant to any Loan Document from Borrower Representative as a
notice or communication from all Borrowers. Each warranty, covenant, agreement
and undertaking made on its behalf by Borrower Representative shall be deemed
for all purposes to have been made by such Borrower and shall be binding upon
and enforceable against such Borrower to the same extent as it if the same had
been made directly by such Borrower.

                                   SECTION 2.

                              AFFIRMATIVE COVENANTS

         Each Credit Party executing this Agreement jointly and severally agrees
as to all Credit Parties that from and after the date hereof and until the
Termination Date:

         2.1.     Compliance with Laws and Contractual Obligations. Each Credit
Party will (a) comply with and shall cause each of its Subsidiaries to comply
with (i) the requirements of all applicable laws, rules, regulations and orders
of any Governmental Authority (including, without limitation, laws, rules,
regulations and orders relating to taxes, employer and employee contributions,
securities, employee retirement and welfare benefits and employee health and
safety) as now in effect and which may be imposed in the future in all
jurisdictions in which any Credit Party or any of its Subsidiaries is now doing
business or may hereafter be doing business; provided that this clause (i) shall
not include environmental protection matters which shall be governed by Section
2.5 and (ii) the obligations, covenants and conditions contained in all
Contractual Obligations of such Credit Party or any of its Subsidiaries other
than those laws, rules, regulations, orders and provisions of such Contractual
Obligations the noncompliance with which could not be reasonably expected to
have, either individually or in the aggregate, a Material Adverse Effect, and
(b) maintain or obtain and shall cause each of its Subsidiaries to maintain or
obtain all licenses, qualifications and permits now held or hereafter required
to be held by such Credit Party or any of its Subsidiaries, for which the loss,
suspension, revocation or failure to obtain or renew, could reasonably be
expected to have, either individually or in the aggregate, a Material Adverse
Effect. This Section 2.1 shall not preclude any Credit Party or its Subsidiaries
from contesting any taxes or other payments, if they are being diligently
contested in good faith in a manner which stays enforcement of any Lien in
respect thereof and if appropriate expense provisions have been recorded in
conformity with GAAP, subject to Section 3.2. Each Credit Party represents and
warrants that it (i) is in

                                     - 22 -
<PAGE>

compliance and each of its Subsidiaries is in compliance with the requirements
of all applicable laws, rules, regulations and orders of any Governmental
Authority and the obligations, covenants and conditions contained in all
Contractual Obligations other than those laws, rules, regulations, orders and
provisions of such Contractual Obligations the noncompliance with which could
not be reasonably expected to have, either individually or in the aggregate, a
Material Adverse Effect, and (ii) maintains and each of its Subsidiaries
maintains all licenses, qualifications and permits referred to above.

         2.2.     Insurance; Damage to or Destruction of Collateral.

                  (a)      The Credit Parties shall, at their sole cost and
expense, maintain the policies of insurance described on Schedule 5.18 as in
effect on the date hereof or otherwise in form and amounts and with insurers
reasonably acceptable to Agent. Such policies of insurance (or the loss payable
and additional insured endorsements delivered to Agent) shall contain provisions
pursuant to which the insurer agrees to provide 30 days prior written notice to
Agent in the event of any non-renewal, cancellation or amendment of any such
insurance policy. If any Credit Party at any time or times hereafter shall fail
to obtain or maintain any of the policies of insurance required above or to pay
all premiums relating thereto, Agent may at any time or times thereafter obtain
and maintain such policies of insurance and pay such premiums and take any other
action with respect thereto that Agent deems advisable. Agent shall have no
obligation to obtain insurance for any Credit Party or pay any premiums
therefor. By doing so, Agent shall not be deemed to have waived any Default or
Event of Default arising from any Credit Party's failure to maintain such
insurance or pay any premiums therefor. All sums so disbursed, including
reasonable attorneys' fees, court costs and other charges related thereto, shall
be payable on demand by Borrowers to Agent and shall be additional Obligations
hereunder secured by the Collateral.

                  (b)      Agent reserves the right at any time upon any change
in any Credit Party's risk profile (including any change in the product mix
maintained by any Credit Party or any laws affecting the potential liability of
such Credit Party) to require additional forms and limits of insurance to, in
Agent's reasonable opinion, adequately protect both Agent's and Lenders'
interests in all or any portion of the Collateral and to ensure that each Credit
Party is protected by insurance in amounts and with coverage customary for its
industry. If reasonably requested by Agent, each Credit Party shall deliver to
Agent from time to time a report of a reputable insurance broker, reasonably
satisfactory to Agent, with respect to its insurance policies.

                  (c)      Each Credit Party shall deliver to Agent, in form and
substance reasonably satisfactory to Agent, endorsements to (i) all "All Risk"
and business interruption insurance naming Agent, on behalf of itself and
Lenders, as loss payee, and (ii) all general liability and other liability
policies naming Agent, on behalf of itself and Lenders, as additional insured.
Each Credit Party irrevocably makes, constitutes and appoints Agent (and all
officers, employees or agents designated by Agent), so long as any Default or
Event of Default has occurred and is continuing or the anticipated insurance
proceeds exceed $2,000,000, as each Credit Party's true and lawful agent and
attorney-in-fact for the purpose of making, settling and adjusting claims under
such "All Risk" policies of insurance, endorsing the name of each Credit Party
on any check or other item of payment for the proceeds of such "All Risk"
policies of insurance and for making all determinations and decisions with
respect to such "All Risk" policies of insurance; provided that Agent shall not
settle any claim without each Credit Party's consent, such consent not to be
unreasonably withheld, provided that no such consent shall be required while a
Default or Event of Default is continuing. Agent shall have no duty to exercise
any rights or powers granted to it pursuant to the foregoing power-of-attorney.
Each Borrower shall promptly notify Agent of any loss, damage, or destruction to
the Collateral in the amount of $250,000 or more, whether or not covered by
insurance. After deducting from any insurance proceeds the expenses, if any,
incurred by Agent in the collection or handling thereof, Agent may, at its
option, apply such proceeds to the reduction

                                     - 23 -
<PAGE>

of the Obligations in accordance with Section 1.5(f), provided that in the case
of insurance proceeds pertaining to any Credit Party other than a Borrower, such
insurance proceeds shall be applied, in the case of a Credit Party that is a
Subsidiary of Borrower, as if such Borrower owned the property that generated
such proceeds and in the case of a Credit Party (other than a Borrower) that
owns the Stock of a Borrower, as if any Borrower owned the property that
generated such proceeds, or permit or require each Credit Party to use such
money, or any part thereof, to replace, repair, restore or rebuild the
Collateral in a diligent and expeditious manner with materials and workmanship
of substantially the same quality as existed before the loss, damage or
destruction. Notwithstanding the foregoing, if the casualty giving rise to such
insurance proceeds could not reasonably be expected to have a Material Adverse
Effect and such insurance proceeds do not exceed $2,000,000 in the aggregate,
Agent shall permit the applicable Credit Party to replace, restore, repair or
rebuild the property; provided that if such Credit Party has not completed or
entered into binding agreements to complete such replacement, restoration,
repair or rebuilding within 180 days of such casualty, Agent may apply such
insurance proceeds to the Obligations in accordance with Section 1.5(f);
provided that in the case of insurance proceeds pertaining to any Credit Party
other than a Borrower, such insurance proceeds shall be applied, in the case of
a Credit Party that is a Subsidiary of Borrower, as if such Borrower owned the
property that generated such proceeds and in the case of a Credit Party (other
than a Borrower) that owns the Stock of a Borrower, as if any Borrower owned the
property that generated such proceeds, or permit or require each Credit Party to
use such money, or any part thereof, to replace, repair, restore or rebuild the
Collateral in a diligent and expeditious manner with materials and workmanship
of substantially the same quality as existed before the loss, damage or
destruction. All insurance proceeds that are to be made available to such
Borrower to replace, repair, restore or rebuild the Collateral shall be applied
by Agent to reduce the outstanding principal balance of the Revolving Loan
(which application shall not result in a permanent reduction of the Revolving
Loan Commitment). All insurance proceeds made available to any Credit Party that
is not a Borrower to replace, repair, restore or rebuild Collateral shall be
deposited in a cash collateral account. Thereafter, such funds shall be made
available to such Borrower or such Credit Party, as applicable, to provide funds
to replace, repair, restore or rebuild the Collateral as follows: (i) such
Borrower shall request a Revolving Credit Advance or release from the cash
collateral account be made to such Borrower or such Credit Party, as applicable
in the amount requested to be released; (ii) so long as the conditions set forth
in Section 7.2 have been met and subject to the provisions of any Mortgage
encumbering such Collateral, Revolving Lenders shall make such Revolving Credit
Advance or Agent shall release funds from the cash collateral account; and (iii)
in the case of insurance proceeds applied against the Revolving Loan, the
Reserve established with respect to such insurance proceeds shall be reduced by
the amount of such Revolving Credit Advance. To the extent not used to replace,
repair, restore or rebuild the Collateral, such insurance proceeds shall be
applied in accordance with Section 1.5(f); provided that in the case of
insurance proceeds pertaining to any Credit Party other than a Borrower, such
insurance proceeds shall be applied, in the case of a Credit Party that is a
Subsidiary of Borrower, as if such Borrower owned the property that generated
such proceeds and in the case of a Credit Party (other than a Borrower) that
owns the Stock of a Borrower, as if any Borrower owned the property that
generated such proceeds.

         2.3.     Inspection; Lender Meeting. Each Credit Party shall permit any
authorized representatives of Agent to visit, audit and inspect any of the
properties of such Credit Party and its Subsidiaries, including its and their
financial and accounting records, and to make copies and take extracts
therefrom, and to discuss its and their affairs, finances and business with its
and their officers and certified public accountants, at such reasonable times
during normal business hours and as often as may be reasonably requested.
Representatives of each Lender will be permitted to accompany representatives of
Agent during each visit, inspection and discussion referred to in the
immediately preceding sentence. Without in any way limiting the foregoing, each
Credit Party will participate and will cause key management personnel of each
Credit Party and its Subsidiaries to participate in a meeting with Agent

                                     - 24 -
<PAGE>

and Lenders at least once during each year, which meeting shall be held at such
time and such place as may be reasonably requested by Agent.

         2.4.     Organizational Existence. Except as otherwise permitted by
Section 3.6, each Credit Party will and will cause its Subsidiaries to at all
times preserve and keep in full force and effect its organizational existence
and all rights and franchises material to its business.

         2.5.     Environmental Matters. Each Credit Party shall and shall cause
each Person within its control to: (a) conduct its operations and keep and
maintain its Real Estate in compliance with all Environmental Laws and
Environmental Permits other than noncompliance that could not reasonably be
expected to have a Material Adverse Effect; (b) implement any and all
investigation, remediation, removal and response actions that are appropriate or
necessary to maintain the value and marketability of the Real Estate or to
otherwise comply in all material respects with Environmental Laws and
Environmental Permits pertaining to the presence, generation, treatment,
storage, use, disposal, transportation or Release of any Hazardous Material on,
at, in, under, above, to, from or about any of its Real Estate; (c) notify Agent
promptly after such Credit Party or any Person within its control becomes aware
of any violation of Environmental Laws or Environmental Permits or any Release
on, at, in, under, above, to, from or about any Real Estate that is reasonably
likely to result in Environmental Liabilities to a Credit Party or its
Subsidiaries in excess of $100,000; and (d) promptly forward to Agent a copy of
any order, notice, request for information or any communication or report
received by such Credit Party or any Person within its control in connection
with any such violation or Release or any other matter relating to any
Environmental Laws or Environmental Permits that could reasonably be expected to
result in Environmental Liabilities in excess of $100,000, in each case whether
or not the Environmental Protection Agency or any Governmental Authority has
taken or threatened any action in connection with any such violation, Release or
other matter. If Agent at any time has a reasonable basis to believe that there
may be a violation of any Environmental Laws or Environmental Permits by any
Credit Party or any Person under its control or any Environmental Liability
arising thereunder, or a Release of Hazardous Materials on, at, in, under,
above, to, from or about any of its Real Estate, that, in each case, could
reasonably be expected to have a Material Adverse Effect, then each Credit Party
and its Subsidiaries shall, upon Agent's written request (i) cause the
performance of such environmental audits including subsurface sampling of soil
and groundwater, and preparation of such environmental reports, at Borrowers'
expense, as Agent may from time to time reasonably request, which shall be
conducted by reputable environmental consulting firms reasonably acceptable to
Agent and shall be in form and substance reasonably acceptable to Agent, and
(ii) permit Agent or its representatives to have access to all Real Estate for
the purpose of conducting such environmental audits and testing as Agent deems
appropriate, including subsurface sampling of soil and groundwater. Borrowers
shall reimburse Agent for the costs of such audits and tests and the same will
constitute a part of the Obligations secured hereunder.

         2.6.     Landlords' Agreements, Mortgagee Agreements, Bailee Letters
and Real Estate Purchases. Each Credit Party shall use reasonable efforts to
obtain a landlord's agreement, mortgagee agreement or bailee letter, as
applicable, from the lessor of each leased property, mortgagee of owned property
or bailee with respect to any warehouse, processor or converter facility or
other location where Collateral is stored or located, which agreement or letter
shall contain a waiver or subordination of all Liens or claims that the
landlord, mortgagee or bailee may assert against the Collateral at that
location, and shall otherwise be reasonably satisfactory in form and substance
to Agent. With respect to such locations or warehouse space leased or owned as
of the Closing Date and thereafter, if Agent has not received a landlord or
mortgagee agreement or bailee letter as of the Closing Date (or, if later, as of
the date such location is acquired or leased), the Eligible Parts and Supplies
and Eligible Equipment at that location shall, in Agent's discretion, be subject
to such Reserves as may be established by Agent in its reasonable credit
judgment. After the Closing Date, no real property or warehouse space shall be
leased by any Credit Party or its Subsidiary and no Parts and Supplies shall be
shipped to a processor or

                                     - 25 -
<PAGE>

converter under arrangements established after the Closing Date without the
prior written consent of Agent (which consent, in Agent's discretion, may be
conditioned upon the exclusion from the Borrowing Base of Eligible Parts and
Supplies and Eligible Equipment at that location or the establishment of
Reserves acceptable to Agent) or, unless and until a satisfactory landlord
agreement or bailee letter, as appropriate, shall first have been obtained with
respect to such location. Each Credit Party shall and shall cause its
Subsidiaries to timely and fully pay and perform their obligations under all
leases and other agreements with respect to each leased location or public
warehouse where any Collateral is or may be located except for such obligations
being diligently contested in good faith and in respect of which, if
appropriate, expense provisions have been recorded in accordance with GAAP.

         2.7.     Conduct of Business. Each Credit Party shall at all times
maintain, preserve and protect all of its assets and properties used or useful
in the conduct of its business, and keep the same in good repair, working order
and condition in all material respects (taking into consideration ordinary wear
and tear) and from time to time make, or cause to be made, all necessary or
appropriate repairs, replacements and improvements thereto consistent with
industry practices; continue to conduct its business substantially as now
conducted or as otherwise permitted hereunder; and transact business only in
such limited liability company, corporate and trade names as are set forth in
Schedule 2.7, which schedule may be updated by the Credit Parties from time to
time with twenty (20) days' prior written notice to Agent.

         2.8.     Further Assurances.

                  (a)      Each Credit Party shall, from time to time, execute
or authorize the execution of such guaranties, financing statements, documents,
control agreements, security agreements and reports as Agent or Requisite
Lenders at any time may reasonably request to evidence, perfect or otherwise
implement the guaranties and security for repayment of the Obligations
contemplated by the Loan Documents.

                  (b)      Promptly, and in any event within ten (10) days after
the Closing Date, for all motor vehicles owned by each Credit Party as of the
Closing Date that are covered by a certificate of title, such Credit Party shall
submit for reissuance with the appropriate state motor vehicle office such motor
vehicle title certificates with the Agent's Lien noted thereon.

                  (c)      Each Credit Party shall, from time to time, cause all
chattel paper (excluding written lease agreements governing Short-Term Rentals)
owned by such Credit Party to be conspicuously legended to indicate that it is
subject to a lien in favor of Agent.

                  (d)      In the event any Credit Party acquires an ownership
interest in real property after the Closing Date, such Credit Party shall
deliver to Agent a fully executed mortgage or deed of trust over such real
property in form and substance similar to the Mortgages delivered concurrently
herewith, with such variations as may be reasonably required by Agent in order
to conform to and/or take advantage of laws of the state in which such real
property is located, together with such title insurance policies, surveys,
appraisals, evidence of insurance, legal opinions, environmental assessments and
other documents and certificates as shall be reasonably required by Agent.

                  (e)      Promptly, and in any event within 30 days after the
acquisition by Borrowers or its Subsidiaries of assets or personal property of
the type that would have constituted Collateral on the Closing Date and
investments of the type that would have constituted Collateral on the Closing
Date, Borrowers will take, or will cause their Subsidiaries to take, all
necessary action, including (i) the filing of appropriate financing statements
under the applicable provisions of the UCC, applicable foreign, domestic or
local laws, rules or regulations in each of the offices where such filing is
necessary or appropriate, (ii) the execution and delivery of Control Agreements,
and (iii) the notation of the Lien of Agent on any

                                     - 26 -
<PAGE>

certificate of title, in each case, to create and perfect a perfected Lien in
such Collateral (or comparable interest under foreign law in the case of foreign
Collateral) pursuant to and to the full extent required by the Security
Agreements and this Agreement.

                  (f)      Each Credit Party shall (i) cause each Person, upon
its becoming a Subsidiary of such Credit Party (provided that this shall not be
construed to constitute consent by any of the Lenders to any transaction
referred to above which is not expressly permitted by the terms of this
Agreement), promptly to guaranty the Obligations and to grant to Agent, for the
benefit of Agent and Lenders, a security interest in the real, personal and
mixed property of such Person to secure the Obligations and (ii) pledge, or
cause to be pledged, to Agent, for the benefit of Agent and Lenders, all of the
Stock of such Subsidiary to secure the Obligations. The documentation for such
guaranty, security and pledge shall be substantially similar to the Loan
Documents executed concurrently herewith with such modifications as are
reasonably requested by Agent and shall be accompanied by such legal opinions
and other documents as Agent may reasonably request. Notwithstanding the
foregoing, in the event that a Person becomes a Subsidiary of a Borrower and
such Person is a "controlled foreign corporation", as defined in Section 957(a)
of the IRC (a "CFC"), of such Borrower, then such Borrower shall (a) not be
obligated to cause such CFC to comply with clause (i) of this subsection (e) and
nothing in this Agreement shall cause any CFC to have any obligation under this
Agreement, and (b) pledge or cause to be pledged no more than sixty-five percent
(65%) of all of the Stock of such CFC, provided that, Borrower shall not be
obligated to pledge or cause to be pledged any assets owned by any CFC
(including the Stock of such CFC owned by another CFC).

         2.9.     Omitted.

         2.10.    Cash Management Systems. Credit Parties shall, and shall cause
each of their Subsidiaries to, enter into Control Agreements with respect to
each deposit account maintained by any Credit Party or any Subsidiary of any
Credit Party as of or after the Closing Date. Each such Control Agreement shall
be in form and substance satisfactory to Agent. Borrowers shall enter into
lockbox agreements in form and substance and with banks acceptable to Agent and
shall direct all Account Debtors to make payments on all Accounts into the
lockboxes established under such agreements. All payments received in the
lockboxes shall promptly, subject to Section 6.5, (i) first, be applied to the
outstanding Obligations other than Letter of Credit Obligations, until paid in
full and (ii) second, following such payment in full, be remitted to the
Borrowers.

                                   SECTION 3.

                               NEGATIVE COVENANTS

         Each Credit Party executing this Agreement jointly and severally agrees

collectively the "Intercompany Notes") to evidence any such intercompany
Indebtedness owing at any time by such obligor Borrower to such obligee

sheet, income statement and cash flow statement of Holdings and its Subsidiaries
(the "Acquisition Pro Forma"), based on recent financial statements, which shall
be complete and shall fairly present in all material respects the assets,
liabilities, financial condition and results of operations of Holdings and its
Subsidiaries in accordance with GAAP consistently applied, but taking into
account such Permitted Acquisition and the funding of all Loans in connection
therewith, and such Acquisition Pro Forma shall reflect that (x) on a pro forma
basis, Holdings and its Subsidiaries would have had a Leverage Ratio not in
excess of 1.2 to 1.0 for the four quarter period reflected in the Compliance
Certificate most recently delivered to Agent pursuant to Section 4.9(l) prior to

prepared in accordance with the Projections (the "Acquisition Projections") and
based upon historical financial data of a recent date reasonably satisfactory to
Agent, taking into account such Permitted Acquisition; and

                                    (C)      a certificate of the chief
financial officer of Borrower Representative to the effect that: (w) Borrowers
(after taking into consideration all rights of contribution and indemnity
Borrower has against Holdings and each other Subsidiary of Holdings) will be
Solvent upon the consummation of the Permitted Acquisition; (x) the Acquisition
Pro Forma fairly presents the financial condition of Holdings and its
Subsidiaries (on a consolidated basis) as of the date thereof after giving
effect to the Permitted Acquisition; (y) the Acquisition Projections are
reasonable estimates of the future financial performance of Holdings and its
Subsidiaries subsequent to the date thereof based upon the historical
performance of Holdings and its Subsidiaries and the Target and show that
Holdings and its Subsidiaries shall continue to be in compliance with the
financial covenants set forth in Section 4 for the three (3) year period
thereafter; and (z) Holdings and its Subsidiaries have completed their due
diligence investigation with respect to the Target and such Permitted
Acquisition, which investigation was conducted in a manner similar to that which
would have been conducted by a prudent purchaser of a comparable business and
the results of which investigation were delivered to Agent and Lenders;

                           (x)      on or prior to the date of such Permitted
Acquisition, Agent shall have received, in form and substance reasonably
satisfactory to Agent, copies of the acquisition agreement and related
agreements and instruments, and all opinions, certificates, lien search results
and other documents reasonably requested by Agent, including those specified in
Section 2.8(e); and

                           (xi)     at the time of such Permitted Acquisition
and after giving effect thereto, no Default or Event of Default has occurred and
is continuing.

                  Notwithstanding the foregoing, the Accounts, Short-Term
Rentals, Parts and Supplies, Equipment and Real Estate of the Target shall not
be included in Eligible Accounts, Eligible Short-Term Rentals, Eligible Parts
and Supplies, Eligible Equipment and Eligible Real Estate without the prior
written consent of Agent and Requisite Lenders. Notwithstanding the foregoing,

such property shall be included in the Aggregate Borrowing Base unless (i) such
Target becomes a Borrower under this Agreement pursuant to an accession or
similar agreement in form and substance satisfactory to Agent, (ii) such Target
shall have delivered in connection therewith such documents, certificates and
legal opinions as Agent shall have reasonably requested in connection with such

forth on Schedule 3.8, (b) transactions in the ordinary course of and pursuant
to the reasonable requirements of the business of any such Credit Party or any

with a Person that is not an Affiliate, (c) payment of reasonable compensation
to officers and employees for services actually rendered to any such Credit
Party or any of its Subsidiaries, (d) payment of director's fees not to exceed
$100,000 in the aggregate for any Fiscal Year of Holdings and (e) upon notice to

shall be delivered to Agent with all necessary endorsements, free and clear of
all Liens except those in favor of Agent and Lenders, (ii) if such assets are
covered by a certificate of title, such certificate of title shall be re-issued
in the name of the transferee Borrower and the Lien of Agent shall be noted on

of all Liens and rights of any other Person, except the Lien in favor of Agent
and Lenders and Permitted Encumbrances of the type described in clause (a), (d),

Advances or cash collateralize Letter of Credit Obligations necessitated by the
reduction in its Borrowing Base and, in the event any such transferred assets

absence of a specific determination by Agent with respect thereto, the proceeds
of any sale of, or other realization upon, all or any part of the Collateral
shall be applied: first, to all Fees, costs and expenses incurred by or owing to

specified in Section 7.2, subject to the delivery of all documents listed on,
the taking of all actions set forth on and the satisfaction of all other
conditions precedent listed in the Closing Checklist attached hereto as Annex C,
all in form and substance, or in a manner, satisfactory to Agent and Lenders.

         7.2.     Conditions to All Loans. Except as otherwise expressly
provided herein, no Lender or L/C Issuer shall be obligated to fund any Advance
or incur any Letter of Credit Obligation, if, as of the date thereof (the
"Funding Date"):

                  (a)      any representation or warranty by any Credit Party
contained herein or in any other Loan Document is untrue or incorrect in any
material respect (without duplication of any materiality qualifier contained
therein) as of such date, except to the extent that such representation or
warranty expressly relates to an earlier date, and Agent or Requisite Lenders
have determined not to make such Advance or incur such Letter of Credit
Obligation as a result of the fact that such warranty or representation is
untrue or incorrect;

                  (b)      any Default or Event of Default has occurred and is
continuing or would result after giving effect to any Advance (or the incurrence
of any Letter of Credit Obligation), and Agent or Requisite Lenders shall have
determined not to make any Advance or incur any Letter of Credit Obligation as a
result of that Default or Event of Default; or

                  (c)      after giving effect to any Advance (or the incurrence
of any Letter of Credit Obligations), (i) the outstanding amount of the
aggregate Revolving Loan would exceed remaining Borrowing Availability (except
as provided in Section 1.1(a)(ii)) or (ii) the outstanding amount of the

                                     - 51 -

<PAGE>

Revolving Loan of the applicable Borrower would exceed such Borrower's separate
Borrowing Base less the outstanding amount of the Swing Line Loan to that
Borrower.

The request and acceptance by any Borrower of the proceeds of any Advance, the
incurrence of any Letter of Credit Obligations or the conversion or continuation
of any Loan into, or as, a LIBOR Loan shall be deemed to constitute, as of the
date thereof, (i) a representation and warranty by Credit Parties that the
conditions in this Section 7.2 have been satisfied and (ii) a reaffirmation by
Borrowers of the cross guaranty provisions set forth in Section 10 and of the
granting and continuance of Agent's Liens, on behalf of itself and Lenders,
pursuant to the Collateral Documents.

                                   SECTION 8.

                          ASSIGNMENT AND PARTICIPATION

         8.1.     Assignment and Participations.

                  (a)      Subject to the terms of this Section 8.1, any Lender
may make an assignment to a Qualified Assignee of, or sale of participations in,
at any time or times, the Loan Documents, Loans, Letter of Credit Obligations
and any Commitment or any portion thereof or interest therein, including any
Lender's rights, title, interests, remedies, powers or duties thereunder. Any
assignment by a Lender shall: (i) require the consent of Agent (which consent
shall not be unreasonably withheld or delayed with respect to a Qualified
Assignee) and the execution of an assignment agreement (an "Assignment
Agreement" substantially in the form attached hereto as Exhibit 8.1 and
otherwise in form and substance reasonably satisfactory to, and acknowledged by,
Agent); (ii) be conditioned on such assignee Lender representing to the
assigning Lender and Agent that it is purchasing the applicable Loans to be
assigned to it for its own account, for investment purposes and not with a view
to the distribution thereof; (iii) after giving effect to any such partial
assignment, the assignee Lender shall have Commitments in an amount at least
equal to $5,000,000 and the assigning Lender shall have retained Commitments in
an amount at least equal to $5,000,000; and (iv) require a payment to Agent of
an assignment fee of $3,500. Notwithstanding the above, Agent may in its sole
and absolute discretion permit any assignment by a Lender to a Person or Persons
that are not Qualified Assignees. In the case of an assignment by a Lender under
this Section 8.1, the assignee shall have, to the extent of such assignment, the
same rights, benefits and obligations as all other Lenders hereunder. The
assigning Lender shall be relieved of its obligations hereunder with respect to
its Commitments or assigned portion thereof from and after the date of such
assignment. Borrowers hereby acknowledge and agree that any assignment shall
give rise to a direct obligation of Borrowers to the assignee and that the
assignee shall be considered to be a "Lender." In all instances, each Lender's
liability to make Loans hereunder shall be several and not joint and shall be
limited to such Lender's Pro Rata Share of the applicable Commitment. In the
event Agent or any Lender assigns or otherwise transfers all or any part of the
Obligations, Agent or any such Lender shall so notify Borrowers and Borrowers
shall, upon the request of Agent or such Lender, execute new Notes in exchange
for the Notes, if any, being assigned. Notwithstanding the foregoing provisions
of this Section 8.1(a), (a) any Lender may at any time pledge the Obligations
held by it and such Lender's rights under this Agreement and the other Loan
Documents to a Federal Reserve Bank, (b) any Lender that is an investment fund
may assign the Obligations held by it and such Lender's rights under this
Agreement and the other Loan Documents to another investment fund managed by the
same investment advisor or pledge such Obligations and rights to trustee for the
benefit of its investors and (c) any Lender may assign the Obligations to an
Affiliate of such Lender or to a Person that is a Lender prior to the date of
such assignment.

                  (b)      Any participation by a Lender of all or any part of
its Commitments shall be made with the understanding that all amounts payable by
Borrowers hereunder shall be determined as if

                                     - 52 -

<PAGE>

that Lender had not sold such participation, and that the holder of any such
participation shall not be entitled to require such Lender to take or omit to
take any action hereunder except actions directly affecting (i) any reduction in
the principal amount of, or interest rate or Fees payable with respect to, any
Loan in which such holder participates, (ii) any extension of the scheduled
amortization of the principal amount of any Loan in which such holder
participates or the final maturity date thereof, and (iii) any release of all or
substantially all of the Collateral (other than in accordance with the terms of
this Agreement, the Collateral Documents or the other Loan Documents). Solely
for purposes of Sections 1.10, 1.11, 8.3 and 9.1, Borrowers acknowledge and
agree that a participation shall give rise to a direct obligation of Borrowers
to the participant and the participant shall be considered to be a "Lender."
Except as set forth in the preceding sentence no Borrower or any other Credit
Party shall have any obligation or duty to any participant. Neither Agent nor
any Lender (other than the Lender selling a participation) shall have any duty
to any participant and may continue to deal solely with the Lender selling a
participation as if no such sale had occurred.

                  (c)      Except as expressly provided in this Section 8.1, no
Lender shall, as between Borrowers and that Lender, or Agent and that Lender, be
relieved of any of its obligations hereunder as a result of any sale,
assignment, transfer or negotiation of, or granting of participation in, all or
any part of the Loans, the Notes or other Obligations owed to such Lender.

                  (d)      Each Credit Party shall assist each Lender permitted
to sell assignments or participations under this Section 8.1 as required to
enable the assigning or selling Lender to effect any such assignment or
participation, including the execution and delivery of any and all agreements,
notes and other documents and instruments as shall be requested and the prompt
preparation of informational materials for, and the participation of management
in meetings with, potential assignees or participants, all on a timetable
established by Agent in its sole discretion. Each Credit Party executing this
Agreement shall certify the correctness, completeness and accuracy of all
descriptions of the Credit Parties and their respective affairs contained in any
selling materials provided by it and all other information provided by it and
included in such materials, except that any Projections delivered by Borrowers
shall only be certified by Borrowers as having been prepared by Borrowers in
compliance with the representations contained in Section 5.5. Agent shall
maintain, on behalf of Borrowers, in its offices located at 335 Madison Avenue,
12th Floor, New York, New York 10017 a "register" for recording the name,
address, commitment and Loans owing to each Lender. The entries in such register
shall be presumptive evidence of the amounts due and owing to each Lender in the
absence of manifest error. Borrowers, Agent and each Lender may treat each
Person whose name is recorded in such register pursuant to the terms hereof as a
Lender for all purposes of this Agreement. The register described herein shall
be available for inspection by Borrower and any Lender, at any reasonable time
upon reasonable prior notice.

                  (e)      A Lender may furnish any information concerning
Credit Parties in the possession of such Lender from time to time to assignees
and participants (including prospective assignees and participants); provided
that such Lender shall obtain from assignees or participants confidentiality
covenants substantially equivalent to those contained in Section 9.13.

                  (f)      So long as no Event of Default has occurred and is
continuing, no Lender shall assign or sell participations in any portion of its
Loans or Commitments to a potential Lender or participant, if, as of the date of
the proposed assignment or sale, the assignee Lender or participant would be
eligible to demand payment in respect of capital adequacy or similar
requirements under Section 1.10(a), to demand increased costs or be entitled not
to fund LIBOR Loans under Section 1.10(b), or would subject Credit Parties to
increased costs in accordance with Section 1.11.

         8.2.     Agent.

                  (a)      Appointment. Each Lender hereby designates and
appoints GE Capital as its Agent under this Agreement and the other Loan
Documents, and each Lender hereby irrevocably authorizes Agent to execute and
deliver the Collateral Documents and to take such action or to refrain from
taking such action on its behalf under the provisions of this Agreement and the
other Loan Documents and to exercise such powers as are set forth herein or
therein, together with such other powers as are reasonably incidental thereto.
Agent is authorized and empowered to amend, modify, or waive any provisions of
this Agreement or the other Loan Documents on behalf of Lenders subject to the
requirement that certain of Lenders' consent be obtained in certain instances as
provided in this Section 8.2 and Section 9.2. The provisions of this Section 8.2
are solely for the benefit of Agent and Lenders and neither Borrowers nor any
other Credit Party shall have any rights as a third party beneficiary of any of
the provisions hereof. In performing its functions and duties under this
Agreement, Agent shall act solely as agent of Lenders and does not assume and
shall not be deemed to have assumed any obligation toward or relationship of
agency or trust with or for Borrowers or any other Credit Party. Agent may
perform any of its duties hereunder, or under the Loan Documents, by or through
its agents or employees. By signing in the spaces below, the Lenders hereby
authorize and direct GE Capital, in its capacity as Agent for the Lenders, to
execute and deliver the Collateral Documents.

                  (b)      Nature of Duties. The duties of Agent shall be
mechanical and administrative in nature. Agent shall not have by reason of this
Agreement a fiduciary relationship in respect of any Lender. Nothing in this
Agreement or any of the Loan Documents, express or implied, is intended to or
shall be construed to impose upon Agent any obligations in respect of this
Agreement or any of the Loan Documents except as expressly set forth herein or
therein. Each Lender shall make its own independent investigation of the
financial condition and affairs of each Credit Party in connection with the
extension of credit hereunder and shall make its own appraisal of the
creditworthiness of each Credit Party, and Agent shall have no duty or
responsibility, either initially or on a continuing basis, to provide any Lender
with any credit or other information with respect thereto (other than as
expressly required herein). If Agent seeks the consent or approval of any
Lenders to the taking or refraining from taking any action hereunder, then Agent
shall send notice thereof to each Lender. Agent shall promptly notify each
Lender any time that the Requisite Lenders or Supermajority Revolving Lenders
have instructed Agent to act or refrain from acting pursuant hereto.

                  (c)      Rights, Exculpation, Etc. Neither Agent nor any of
its officers, directors, employees or agents shall be liable to any Lender for
any action taken or omitted by them hereunder or under any of the Loan
Documents, or in connection herewith or therewith, except that Agent shall be
liable to the extent of its own gross negligence or willful misconduct as
determined by a final non-appealable order by a court of competent jurisdiction.
Agent shall not be liable for any apportionment or distribution of payments made
by it in good faith and if any such apportionment or distribution is
subsequently determined to have been made in error the sole recourse of any
Lender to whom payment was due but not made, shall be to recover from other
Lenders any payment in excess of the amount to which they are determined to be
entitled (and such other Lenders hereby agree to return to such Lender any such
erroneous payments received by them). In no event shall Agent be liable for
punitive, special, consequential, incidental, exemplary or other similar
damages. In performing its functions and duties hereunder, Agent shall exercise
the same care which it would in dealing with loans for its own account, but
neither Agent nor any of its agents or representatives shall be responsible to
any Lender for any recitals, statements, representations or warranties herein or
for the execution, effectiveness, genuineness, validity, enforceability,
collectibility, or sufficiency of this Agreement or any of the Loan Documents or
the transactions contemplated thereby, or for the financial condition of any
Credit Party. Agent shall not be required to make any inquiry concerning either
the performance or observance of any of the terms, provisions or conditions of
this Agreement or any of the Loan Documents or the financial condition of

                                     - 54 -

<PAGE>

any Credit Party, or the existence or possible existence of any Default or Event
of Default. Agent may at any time request instructions from Requisite Lenders,
Supermajority Revolving Lenders or all affected Lenders with respect to any
actions or approvals which by the terms of this Agreement or of any of the Loan
Documents Agent is permitted or required to take or to grant. If such
instructions are promptly requested, Agent shall be absolutely entitled to
refrain from taking any action or to withhold any approval and shall not be
under any liability whatsoever to any Person for refraining from any action or
withholding any approval under any of the Loan Documents until it shall have
received such instructions from the Requisite Lenders, Supermajority Revolving
Lenders or such other portion of the Lenders as shall be prescribed by this
Agreement. Without limiting the foregoing, no Lender shall have any right of
action whatsoever against Agent as a result of Agent acting or refraining from
acting under this Agreement or any of the other Loan Documents in accordance
with the instructions of Requisite Lenders, Supermajority Revolving Lenders or
all affected Lenders, as applicable; and, notwithstanding the instructions of
Requisite Lenders, Supermajority Revolving Lenders or all affected Lenders, as
applicable, Agent shall have no obligation to take any action if it believes, in
good faith, that such action is deemed to be illegal by Agent or exposes Agent
to any liability for which it has not received satisfactory indemnification in
accordance with Section 8.2(e).

                  (d)      Reliance. Agent shall be entitled to rely, and shall
be fully protected in relying, upon any written or oral notices, statements,
certificates, orders or other documents or any telephone message or other
communication (including any writing, telex, fax or telegram) believed by it in
good faith to be genuine and correct and to have been signed, sent or made by
the proper Person, and with respect to all matters pertaining to this Agreement
or any of the Loan Documents and its duties hereunder or thereunder. Agent shall
be entitled to rely upon the advice of legal counsel, independent accountants,
and other experts selected by Agent in its sole discretion.

                  (e)      Indemnification. Lenders will reimburse and indemnify
Agent for and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses (including, without
limitation, attorneys' fees and expenses), advances or disbursements of any kind
or nature whatsoever which may be imposed on, incurred by, or asserted against
Agent in any way relating to or arising out of this Agreement or any of the Loan
Documents or any action taken or omitted by Agent under this Agreement or any of
the Loan Documents, in proportion to each Lender's Pro Rata Share, but only to
the extent that any of the foregoing is not reimbursed by Borrowers; provided,
however, that no Lender shall be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses, advances or disbursements to the extent resulting from Agent's gross
negligence or willful misconduct as determined by a final non-appealable order
by a court of competent jurisdiction. If any indemnity furnished to Agent for
any purpose shall, in the opinion of Agent, be insufficient or become impaired,
Agent may call for additional indemnity and cease, or not commence, to do the
acts indemnified against even if so directed by the Requisite Lenders,
Supermajority Revolving Lenders or such other portion of the Lenders as shall be
prescribed by this Agreement until such additional indemnity is furnished. The
obligations of Lenders under this Section 8.2(e) shall survive the payment in
full of the Obligations and the termination of this Agreement.

                  (f)      GE Capital Individually. With respect to its
Commitments hereunder, GE Capital shall have and may exercise the same rights
and powers hereunder and is subject to the same obligations and liabilities as
and to the extent set forth herein for any other Lender. The terms "Lenders",
"Requisite Lenders", "Supermajority Revolving Lenders" or any similar terms
shall, unless the context clearly otherwise indicates, include GE Capital in its
individual capacity as a Lender or one of the Requisite Lenders or Supermajority
Revolving Lenders. GE Capital, either directly or through strategic
affiliations, may lend money to, acquire equity or other ownership interests in,
provide advisory services to and generally engage in any kind of banking, trust
or other business with any Credit Party as if it were not acting as Agent
pursuant hereto and without any duty to account therefor to Lenders. GE Capital,

                                     - 55 -

<PAGE>

either directly or through strategic affiliations, may accept fees and other
consideration from any Credit Party for services in connection with this
Agreement or otherwise without having to account for the same to Lenders.

                  (g)      Successor Agent.

                           (i)      Resignation. Agent may resign from the
performance of all its agency functions and duties hereunder at any time by
giving at least thirty (30) Business Days' prior written notice to Borrower
Representative and Lenders. Such resignation shall take effect upon the
acceptance by a successor Agent of appointment pursuant to clause (ii) below or
as otherwise provided in clause (ii) below.

                           (ii)     Appointment of Successor. Upon any such
notice of resignation pursuant to clause (i) above, Requisite Lenders shall
appoint a successor Agent which, unless an Event of Default has occurred and is
continuing, shall be reasonably acceptable to Borrowers. If a successor Agent
shall not have been so appointed within the thirty (30) Business Day period
referred to in clause (i) above, the retiring Agent, upon notice to Borrower
Representative, shall then appoint a successor Agent who shall serve as Agent
until such time, if any, as Requisite Lenders appoint a successor Agent as
provided above.

                           (iii)    Successor Agent. Upon the acceptance of any
appointment as Agent under the Loan Documents by a successor Agent, such
successor Agent shall thereupon 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 under the Loan
Documents. After any retiring Agent's resignation as Agent, the provisions of
this Section 8.2 shall continue to inure to its benefit as to any actions taken
or omitted to be taken by it in its capacity as Agent.

                  (h)      Collateral Matters.

                           (i)      Release of Collateral. Lenders hereby
irrevocably authorize Agent, at its option and in its discretion, to release any
Lien granted to or held by Agent upon any Collateral (x) upon the Termination
Date or (y) constituting property being sold or disposed of if Borrowers (or any
of them) certify to Agent that the sale or disposition is made in compliance
with the provisions of this Agreement (and Agent may rely in good faith
conclusively on any such certificate, without further inquiry).

                           (ii)     Confirmation of Authority; Execution of
Releases. Without in any manner limiting Agent's authority to act without any
specific or further authorization or consent by Lenders (as set forth in Section
8.2(h)(i)), each Lender agrees to confirm in writing, upon request by Agent or
Borrower Representative, the authority to release any Collateral conferred upon
Agent under clauses (x) and (y) of Section 8.2(h)(i). Upon receipt by Agent of
any required confirmation from the Requisite Lenders of its authority to release
any particular item or types of Collateral, and upon at least ten (10) Business
Days' prior written request by Borrower Representative, Agent shall (and is
hereby irrevocably authorized by Lenders to) execute such documents as may be
necessary to evidence the release of the Liens granted to Agent upon such
Collateral; provided, however, that (x) Agent shall not be required to execute
any such document on terms which, in Agent's opinion, would expose Agent to
liability or create any obligation or entail any consequence other than the
release of such Liens without recourse or warranty, and (y) such release shall
not in any manner discharge, affect or impair the Obligations or any Liens upon
(or obligations of any Credit Party, in respect of), all interests retained by
any Credit Party, including the proceeds of any sale, all of which shall
continue to constitute part of the Collateral.

                                     - 56 -

<PAGE>

                           (iii)    Absence of Duty. Agent shall have no
obligation whatsoever to any Lender, L/C Issuer or any other Person to assure
that the property covered by the Collateral Documents exists or is owned by
Borrowers or any other Credit Party or is cared for, protected or insured or has
been encumbered or that the Liens granted to Agent have been properly or
sufficiently or lawfully created, perfected, protected or enforced or are
entitled to any particular priority, or to exercise at all or in any particular
manner or under any duty of care, disclosure or fidelity, or to continue
exercising, any of the rights, authorities and powers granted or available to
Agent in this Section 8.2(h) or in any of the Loan Documents, it being
understood and agreed that in respect of the property covered by the Collateral
Documents or any act, omission or event related thereto, Agent may act in any
manner it may deem appropriate, in its discretion, given Agent's own interest in
property covered by the Collateral Documents as one of the Lenders and that
Agent shall have no duty or liability whatsoever to any of the other Lenders,
provided that Agent shall exercise the same care which it would in dealing with
loans for its own account.

                  (i)      Agency for Perfection. Agent and each Lender hereby
appoint each other Lender as agent for the purpose of perfecting Agent's
security interest in assets which, in accordance with the Code in any applicable
jurisdiction, can be perfected by possession or control. Should any Lender
(other than Agent) obtain possession or control of any such assets, such Lender
shall notify Agent thereof, and, promptly upon Agent's request therefor, shall
deliver such assets to Agent or in accordance with Agent's instructions or
transfer control to Agent in accordance with Agent's instructions. Each Lender
agrees that it will not have any right individually to enforce or seek to
enforce any Collateral Document or to realize upon any collateral security for
the Loans unless instructed to do so by Agent in writing, it being understood
and agreed that such rights and remedies may be exercised only by Agent.

                  (j)      Notice of Default. Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default except
with respect to defaults in the payment of principal, interest and Fees required
to be paid to Agent for the account of Lenders, unless Agent shall have received
written notice from a Lender or Borrower Representative referring to this
Agreement, describing such Default or Event of Default and stating that such
notice is a "notice of default". Agent will use reasonable efforts to notify
each Lender of its receipt of any such notice, unless such notice is with
respect to defaults in the payment of principal, interest and fees, in which
case Agent will notify each Lender of its receipt of such notice. Agent shall
take such action with respect to such Default or Event of Default as may be
requested by Requisite Lenders in accordance with Section 6. Unless and until
Agent has received any such request, Agent may (but shall not be obligated to)
take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable or in the best interests
of Lenders.

                  (k)      Lender Actions against Collateral. Each Lender agrees
that it will not take any action, nor institute any actions or proceedings, with
respect to the Loans, against any Borrower or any Credit Party hereunder or
under the other Loan Documents or against any of the Real Estate encumbered by
Mortgages without the consent of the Required Lenders. With respect to any
action by Agent to enforce the rights and remedies of Agent and the Lenders
under this Agreement and the other Loan Documents, each Lender hereby consents
to the jurisdiction of the court in which such action is maintained, and agrees
to deliver its Notes to Agent to the extent necessary to enforce the rights and
remedies of Agent for the benefit of the Lenders under the Mortgages in
accordance with the provisions hereof.

         8.3.     Set Off and Sharing of Payments. In addition to any rights now
or hereafter granted under applicable law and not by way of limitation of any
such rights, during the continuance of any Event of Default, each Lender is
hereby authorized by Borrowers at any time or from time to time, with reasonably
prompt subsequent notice to Borrower Representative (any prior or
contemporaneous notice

                                     - 57 -

<PAGE>

being hereby expressly waived) to set off and to appropriate and to apply any
and all (A) balances held by such Lender at any of its offices for the account
of any Borrower or any of its Subsidiaries (regardless of whether such balances
are then due to Borrower or its Subsidiaries), and (B) other property at any
time held or owing by such Lender to or for the credit or for the account of any
Borrower or any of its Subsidiaries, against and on account of any of the
Obligations; except that no Lender shall exercise any such right without the
prior written consent of Agent. Any Lender exercising a right to set off shall
purchase for cash (and the other Lenders shall sell) interests in each of such
other Lender's Pro Rata Share of the Obligations as would be necessary to cause
all Lenders to share the amount so set off with each other Lender in accordance
with their respective Pro Rata Shares. Borrowers agree, to the fullest extent
permitted by law, that any Lender may exercise its right to set off with respect
to amounts in excess of its Pro Rata Share of the Obligations and upon doing so
shall deliver such amount so set off to the Agent for the benefit of all Lenders
in accordance with their Pro Rata Shares.

         8.4.     Disbursement of Funds. Agent may, on behalf of Lenders,
disburse funds to Borrowers for Loans requested. Each Lender shall reimburse
Agent on demand for all funds disbursed on its behalf by Agent, or if Agent so
requests, each Lender will remit to Agent its Pro Rata Share of any Loan before
Agent disburses same to Borrowers. If Agent elects to require that each Lender
make funds available to Agent prior to a disbursement by Agent to Borrowers,
Agent shall advise each Lender by telephone or fax of the amount of such
Lender's Pro Rata Share of the Loan requested by Borrower Representative no
later than 1:00 p.m. (New York time) on the Funding Date applicable thereto, and
each such Lender shall pay Agent such Lender's Pro Rata Share of such requested
Loan, in same day funds, by wire transfer to Agent's account on such Funding
Date. If any Lender fails to pay the amount of its Pro Rata Share within one (1)
Business Day after Agent's demand, Agent shall promptly notify Borrower
Representative, and Borrowers shall immediately repay such amount to Agent. Any
repayment required pursuant to this Section 8.4 shall be without premium or
penalty. Nothing in this Section 8.4 or elsewhere in this Agreement or the other
Loan Documents, including the provisions of Section 8.5, shall be deemed to
require Agent to advance funds on behalf of any Lender or to relieve any Lender
from its obligation to fulfill its commitments hereunder or to prejudice any
rights that Agent or Borrowers may have against any Lender as a result of any
default by such Lender hereunder.

         8.5.     Disbursements of Advances; Payment.

                  (a)      Advances; Payments.

                           (i)      Revolving Lenders shall refund or
participate in the Swing Line Loan in accordance with clauses (iii) and (iv) of
Section 1.1(c). If the Swing Line Lender declines to make a Swing Line Loan or
if Swing Line Availability is zero, Agent shall notify Revolving Lenders,
promptly after receipt of a Notice of Revolving Credit Advance and in any event
prior to 1:00 p.m. (New York time) on the date such Notice of a Revolving Credit
Advance is received, by fax, telephone or other similar form of transmission.
Each Revolving Lender shall make the amount of such Lender's Pro Rata Share of
such Revolving Credit Advance available to Agent in same day funds by wire
transfer to Agent's account as set forth in Section 1.1(e) not later than 3:00
p.m. (New York time) on the requested Funding Date in the case of an Index Rate
Loans and not later than 11:00 a.m. (New York time) on the requested Funding
Date in the case of a LIBOR Loan. After receipt of such wire transfers (or, in
the Agent's sole discretion, before receipt of such wire transfers), subject to
the terms hereof, Agent shall make the requested Revolving Credit Advance to
Borrowers as designated by Borrower Representative in the Notice of Revolving
Credit Advance. All payments by each Revolving Lender shall be made without
setoff, counterclaim or deduction of any kind.

                           (ii)     At least once each calendar week or more
frequently at Agent's election (each, a "Settlement Date"), Agent shall advise
each Lender by telephone or fax of the amount of such

                                     - 58 -

<PAGE>

Lender's Pro Rata Share of principal, interest and Fees paid for the benefit of
Lenders with respect to each applicable Loan. Provided that each Lender has
funded all payments and Advances required to be made by it and purchased all
participations required to be purchased by it under this Agreement and the other
Loan Documents as of such Settlement Date, Agent shall pay to each Lender such
Lender's Pro Rata Share of principal, interest and Fees paid by Borrowers since
the previous Settlement Date for the benefit of such Lender on the Loans held by
it. Such payments shall be made by wire transfer to such Lender's account (as
specified by such Lender in Annex E or the applicable Assignment Agreement) not
later than 2:00 p.m. (New York time) on the next Business Day following each
Settlement Date. To the extent that any Lender (a "Non-Funding Lender") has
failed to fund all such payments and Advances or failed to fund the purchase of
all such participations, Agent shall be entitled to set off the funding
shortfall against that Non-Funding Lender's Pro Rata Share of all payments
received from Borrowers.

                  (b)      Availability of Lender's Pro Rata Share. Agent may
assume that each Revolving Lender will make its Pro Rata Share of each Revolving
Credit Advance available to Agent on each Funding Date. If such Pro Rata Share
is not, in fact, paid to Agent by such Revolving Lender when due, Agent will be
entitled to recover such amount on demand from such Revolving Lender without
setoff, counterclaim or deduction of any kind. If any Revolving Lender fails to
pay the amount of its Pro Rata Share forthwith upon Agent's demand, Agent shall
promptly notify Borrower Representative and Borrowers shall immediately repay
such amount to Agent. Nothing in this Section 8.5(b) or elsewhere in this
Agreement or the other Loan Documents shall be deemed to require Agent to
advance funds on behalf of any Revolving Lender or to relieve any Revolving
Lender from its obligation to fulfill its Commitments hereunder or to prejudice
any rights that Borrowers may have against any Revolving Lender as a result of
any default by such Revolving Lender hereunder. To the extent that Agent
advances funds to Borrowers on behalf of any Revolving Lender and is not
reimbursed therefor on the same Business Day as such Advance is made, Agent
shall be entitled to retain for its account all interest accrued on such Advance
until reimbursed by the applicable Revolving Lender.

                  (c)      Return of Payments.

                           (i)      If Agent pays an amount to a Lender under
this Agreement in the belief or expectation that a related payment has been or
will be received by Agent from Borrowers and such related payment is not
received by Agent, then Agent will be entitled to recover such amount from such
Lender on demand without setoff, counterclaim or deduction of any kind.

                           (ii)     If Agent determines at any time that any
amount received by Agent under this Agreement must be returned to any Borrower
or paid to any other Person pursuant to any insolvency law or otherwise, then,
notwithstanding any other term or condition of this Agreement or any other Loan
Document, Agent will not be required to distribute any portion thereof to any
Lender. In addition, each Lender will repay to Agent on demand any portion of
such amount that Agent has distributed to such Lender, together with interest at
such rate, if any, as Agent is required to pay to any Borrower or such other
Person, without setoff, counterclaim or deduction of any kind.

                  (d)      Non-Funding Lenders. The failure of any Non-Funding
Lender to make any Revolving Credit Advance or any payment required by it
hereunder, or to purchase any participation in any Swing Line Loan to be made or
purchased by it on the date specified therefor shall not relieve any other
Lender (each such other Revolving Lender, an "Other Lender") of its obligations
to make such Advance or purchase such participation on such date, but neither
any Other Lender nor Agent shall be responsible for the failure of any
Non-Funding Lender to make an Advance, purchase a participation or make any
other payment required hereunder. Notwithstanding anything set forth herein to
the contrary, a Non-Funding Lender shall not have any voting or consent rights
under or with respect to any Loan Document or constitute a "Lender" or a
"Revolving Lender" (or be included in the calculation of

                                     - 59 -

<PAGE>

"Requisite Lenders" or "Supermajority Revolving Lenders" hereunder) for any
voting or consent rights under or with respect to any Loan Document.

                  (e)      Dissemination of Information. Agent shall use
reasonable efforts to provide Lenders with any notice of Default or Event of
Default received by Agent from, or delivered by Agent to, any Credit Party, with
notice of any Event of Default of which Agent has actually become aware and with
notice of any action taken by Agent following any Event of Default; provided,
that Agent shall not be liable to any Lender for any failure to do so.

                  (f)      Actions in Concert. Anything in this Agreement to the
contrary notwithstanding, each Lender hereby agrees with each other Lender that
no Lender shall take any action to protect or enforce its rights arising out of
this Agreement or the Notes (including exercising any rights of setoff) without
first obtaining the prior written consent of Agent and Requisite Lenders, it
being the intent of Lenders that any such action to protect or enforce rights
under this Agreement and the Notes shall be taken in concert and at the
direction or with the consent of Agent or Requisite Lenders.

                                   SECTION 9.

                                 MISCELLANEOUS

         9.1.     Indemnities. Borrowers agree, jointly and severally, to
indemnify, pay, and hold Agent, each Lender, each L/C Issuer and their
respective officers, directors, employees, agents, and attorneys (the
"Indemnitees") harmless from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, claims, costs and
expenses (including all reasonable fees and expenses of counsel to such
Indemnitees) of any kind or nature whatsoever that may be imposed on, incurred
by, or asserted against the Indemnitee as a result of such Indemnitees being a
party to this Agreement or the transactions consummated pursuant to this
Agreement or otherwise relating to any of the Related Transactions; provided,
that Borrowers shall have no obligation to an Indemnitee hereunder with respect
to liabilities to the extent resulting from the gross negligence or willful
misconduct of that Indemnitee as determined by a court of competent
jurisdiction. If and to the extent that the foregoing undertaking may be
unenforceable for any reason, Borrowers agree to make the maximum contribution
to the payment and satisfaction thereof which is permissible under applicable
law.

         9.2.     Amendments and Waivers.

                  (a)      Except for actions expressly permitted to be taken by
Agent, no amendment, modification, termination or waiver of any provision of
this Agreement or any other Loan Document, or any consent to any departure by
any Credit Party therefrom, shall in any event be effective unless the same
shall be in writing and signed by Borrowers, and by Requisite Lenders,
Supermajority Revolving Lenders or all affected Lenders, as applicable. Except
as set forth in clauses (b) and (c) below, all such amendments, modifications,
terminations or waivers requiring the consent of any Lenders shall require the
written consent of Requisite Lenders.

                  (b)      No amendment, modification, termination or waiver of
or consent with respect to any provision of this Agreement that increases the
percentage advance rates set forth in the definition of the Holdings Borrowing
Base Certificate, Penhall Borrowing Base, the Bob Mack Borrowing Base or the
Penhall Leasing Borrowing Base, or that makes less restrictive the
nondiscretionary criteria for exclusion from Eligible Accounts, Eligible
Short-Term Rentals, Eligible Parts and Supplies and Eligible Equipment set forth
in Exhibits 4.9(e)(i), 4.9(e)(ii), and 4.9(e)(iii) and from Eligible Real Estate
set forth in Exhibit 4.9(e)(iv), shall be effective unless the same shall be in
writing and signed by Agent, Supermajority Revolving Lenders and Borrowers. No
amendment, modification, termination or waiver of or consent

                                     - 60 -

<PAGE>

with respect to any provision of this Agreement that waives compliance with the
conditions precedent set forth in Section 7.2 to the making of any Loan or the
incurrence of any Letter of Credit Obligations shall be effective unless the
same shall be in writing and signed by Agent, Requisite Lenders and Borrowers.

                  (c)      No amendment, modification, termination or waiver
shall, unless in writing and signed by Agent and each Lender directly affected
thereby: (i) increase the principal amount of any Lender's Commitment (which
action shall be deemed to directly affect all Lenders); (ii) reduce the
principal of, rate of interest on or Fees payable with respect to any Loan or
Letter of Credit Obligations of any affected Lender; (iii) extend any scheduled
payment date or final maturity date of the principal amount of any Loan of any
affected Lender; (iv) waive, forgive, defer, extend or postpone any payment of
interest or Fees as to any affected Lender (which action shall be deemed only to
affect those Lenders to whom such payments are made); (v) release any Guaranty
or, except as otherwise permitted in Section 3.7, release Collateral with a book
value exceeding 5% of the book value of all assets in the aggregate in any one
(1) year (which action shall be deemed to directly affect all Lenders); (vi)
change the percentage of the Commitments or of the aggregate unpaid principal
amount of the Loans that shall be required for Lenders or any of them to take
any action hereunder (which action shall be deemed to directly affect all
Lenders); and (vii) amend or waive this Section 9.2 or the definitions of the
terms "Requisite Lenders" or "Supermajority Revolving Lenders" insofar as such
definitions affect the substance of this Section 9.2 (which action shall be
deemed to directly affect all Lenders). Furthermore, no amendment, modification,
termination or waiver affecting the rights or duties of Agent or L/C Issuers
under this Agreement or any other Loan Document shall be effective unless in
writing and signed by Agent or L/C Issuers, as the case may be, in addition to
Lenders required hereinabove to take such action. Each amendment, modification,
termination or waiver shall be effective only in the specific instance and for
the specific purpose for which it was given. No amendment, modification,
termination or waiver shall be required for Agent to take additional Collateral
pursuant to any Loan Document. No amendment, modification, termination or waiver
of any provision of any Note shall be effective without the written concurrence
of the holder of that Note. No notice to or demand on any Credit Party in any
case shall entitle such Credit Party or any other Credit Party to any other or
further notice or demand in similar or other circumstances. Any amendment,
modification, termination, waiver or consent effected in accordance with this
Section 9.2 shall be binding upon each holder of the Notes at the time
outstanding and each future holder of the Notes.

         9.3.     Notices. Any notice or other communication required shall be
in writing addressed to the respective party as set forth below and may be
personally served, telecopied, sent by overnight courier service or U.S. mail

                                               signature page hereto or in the
                                               applicable Assignment Agreement

         9.4.     Failure or Indulgence Not Waiver; Remedies Cumulative. No
failure or delay on the part of Agent or any Lender to exercise, nor any partial
exercise of, any power, right or privilege hereunder or under any other Loan
Documents shall impair such power, right, or privilege or be construed to be a
waiver of any Default or Event of Default. All rights and remedies existing
hereunder or under any other Loan Document are cumulative to and not exclusive
of any rights or remedies otherwise available.

         9.5.     Marshaling; Payments Set Aside. Neither Agent nor any Lender
shall be under any obligation to marshal any assets in payment of any or all of
the Obligations. To the extent that Borrowers make payment(s) or Agent enforces
its Liens or Agent or any Lender exercises its right of set-off, and such
payment(s) or the proceeds of such enforcement or set-off is subsequently
invalidated, declared to be

                                     - 62 -

<PAGE>

fraudulent or preferential, set aside, or required to be repaid by anyone, then
to the extent of such recovery, the Obligations or part thereof originally
intended to be satisfied, and all Liens, rights and remedies therefor, shall be
revived and continued in full force and effect as if such payment had not been
made or such enforcement or set-off had not occurred.

         9.6.     Severability. The invalidity, illegality, or unenforceability
in any jurisdiction of any provision under the Loan Documents shall not affect
or impair the remaining provisions of the Loan Documents.

         9.7.     Lenders' Obligations Several; Independent Nature of Lenders'
Rights. The obligation of each Lender hereunder is several and not joint and no
Lender shall be responsible for the obligation or commitment of any other Lender
hereunder. In the event that any Lender at any time should fail to make a Loan
as herein provided, the Lenders, or any of them, at their sole option, may make
the Loan that was to have been made by the Lender so failing to make such Loan.
Nothing contained in any Loan Document and no action taken by Agent or any
Lender pursuant hereto or thereto shall be deemed to constitute Lenders to be a
partnership, an association, a joint venture or any other kind of entity. The
amounts payable at any time hereunder to each Lender shall be a separate and
independent debt.

         9.8.     Headings. Section and subsection headings are included herein
for convenience of reference only and shall not constitute a part of this
Agreement for any other purposes or be given substantive effect.

         9.9.     Applicable Law. THIS AGREEMENT AND EACH OF THE OTHER LOAN
DOCUMENTS WHICH DOES NOT EXPRESSLY SET FORTH APPLICABLE LAW SHALL BE GOVERNED BY
AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE
STATE OF NEW YORK, WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES WHICH SHALL BE
DEEMED NOT TO INCLUDE SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW.

         9.10.    Successors and Assigns. This Agreement shall be binding upon
and inure to the benefit of the parties hereto and their respective successors
and assigns except that Borrowers may not assign their rights or obligations
hereunder without the written consent of all Lenders.

         9.11.    No Fiduciary Relationship; Limited Liability. No provision in
the Loan Documents and no course of dealing between the parties shall be deemed
to create any fiduciary duty owing to any Credit Party by Agent or any Lender.
Each Credit Party agrees that neither Agent nor any Lender shall have liability
to such Credit Party (whether sounding in tort, contract or otherwise) for
losses suffered by such Credit Party in connection with, arising out of, or in
any way related to the transactions contemplated and the relationship
established by the Loan Documents, or any act, omission or event occurring in
connection therewith, unless and to the extent that it is determined that such
losses resulted from the gross negligence or willful misconduct of the party
from which recovery is sought as determined by a final non-appealable order by a
court of competent jurisdiction. Neither Agent nor any Lender shall have any
liability with respect to, and each Credit Party hereby waives, releases and
agrees not to sue for, any special, indirect or consequential damages suffered
by such Credit Party in connection with, arising out of, or in any way related
to the Loan Documents or the transactions contemplated thereby.

         9.12.    Construction. Agent, each Lender, Borrowers and each other
Credit Party acknowledge that each of them has had the benefit of legal counsel
of its own choice and has been afforded an opportunity to review the Loan
Documents with its legal counsel and that the Loan Documents shall be construed
as if jointly drafted by Agent, each Lender, Borrowers and each other Credit
Party.

         9.13.    Confidentiality. Agent and each Lender agree to exercise their
best efforts to keep confidential any non-public information delivered pursuant
to the Loan Documents and identified as such by Borrowers and not to disclose
such information to Persons other than to potential assignees or participants or
to Persons employed by or engaged by Agent, a Lender or a Lender's assignees or
participants including attorneys, auditors, professional consultants, rating
agencies, insurance industry associations and portfolio management services. The
confidentiality provisions contained in this Section 9.13 shall not apply to
disclosures (i) required to be made by Agent or any Lender to any regulatory or
governmental agency or pursuant to legal process or (ii) consisting of general
portfolio information that does not identify Borrowers. The obligations of Agent
and Lenders under this Section 9.13 shall supersede and replace the obligations
of Agent and Lenders under any confidentiality agreement in respect of this
financing executed and delivered by Agent or any Lender prior to the date
hereof. Notwithstanding anything herein to the contrary, non-public information
shall not include, and each party (and each employee, representative or other
agent of such party) may disclose to any and all Persons, without limitation of
any kind, any information with respect to the United States federal tax
treatment and tax structure of the transactions contemplated hereby and all
materials of any kind (including opinions or other United States federal tax
analyses) that are provided to such party relating to such tax treatment and tax
structure. To the extent not inconsistent with the immediately preceding
sentence, this authorization does not extend to disclosure of any other
information, including without limitation (a) the identities of participants or
potential participants in this transaction, (b) the existence or status of any
negotiations, or (c) any other term or detail, or portion of any documents or
other materials, not related to the tax treatment or tax structure of the
transaction.

         9.14.    CONSENT TO JURISDICTION. BORROWERS AND CREDIT PARTIES HEREBY
CONSENT TO THE JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN NEW
YORK COUNTY, STATE OF NEW YORK AND IRREVOCABLY AGREE THAT, SUBJECT TO AGENT'S
ELECTION, ALL ACTIONS OR PROCEEDINGS ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR THE OTHER LOAN DOCUMENTS SHALL BE LITIGATED IN SUCH COURTS.
BORROWERS AND CREDIT PARTIES EXPRESSLY SUBMIT AND CONSENT TO THE JURISDICTION OF
THE AFORESAID COURTS AND WAIVE ANY DEFENSE OF FORUM NON CONVENIENS. BORROWERS

AGREE THAT ALL SUCH SERVICE OF PROCESS MAY BE MADE UPON BORROWERS AND CREDIT
PARTIES BY CERTIFIED OR REGISTERED MAIL, RETURN RECEIPT REQUESTED, ADDRESSED TO
BORROWER REPRESENTATIVE, AT THE ADDRESS SET FORTH IN THIS AGREEMENT AND SERVICE
SO MADE SHALL BE COMPLETE TEN (10) DAYS AFTER THE SAME HAS BEEN POSTED. IN ANY
LITIGATION, TRIAL, ARBITRATION OR OTHER DISPUTE RESOLUTION PROCEEDING RELATING
TO THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS, ALL DIRECTORS, OFFICERS,
EMPLOYEES AND AGENTS OF BORROWERS, CREDIT PARTIES OR ANY OF THEIR AFFILIATES
SHALL BE DEEMED TO BE EMPLOYEES OR MANAGING AGENTS OF BORROWERS OR SUCH CREDIT
PARTIES FOR PURPOSES OF ALL APPLICABLE LAW OR COURT RULES REGARDING THE
PRODUCTION OF WITNESSES BY NOTICE FOR TESTIMONY (WHETHER IN A DEPOSITION, AT
TRIAL OR OTHERWISE). BORROWERS AND CREDIT PARTIES AGREE THAT AGENT'S OR ANY
LENDER'S COUNSEL IN ANY SUCH DISPUTE RESOLUTION PROCEEDING MAY EXAMINE ANY OF
THESE INDIVIDUALS AS IF UNDER CROSS-EXAMINATION AND THAT ANY DISCOVERY
DEPOSITION OF ANY OF THEM MAY BE USED IN THAT PROCEEDING AS IF IT WERE AN
EVIDENCE DEPOSITION. BORROWERS AND CREDIT PARTIES IN ANY EVENT WILL USE ALL

EACH LENDER HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR
CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS. BORROWERS, CREDIT PARTIES, AGENT AND EACH LENDER ACKNOWLEDGE THAT
THIS WAIVER IS A MATERIAL INDUCEMENT TO ENTER INTO A BUSINESS RELATIONSHIP, THAT
EACH HAS RELIED ON THE WAIVER IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS AND THAT EACH WILL CONTINUE TO RELY ON THE WAIVER IN THEIR RELATED
FUTURE DEALINGS. BORROWERS, CREDIT PARTIES, AGENT AND EACH LENDER WARRANT AND
REPRESENT THAT EACH HAS HAD THE OPPORTUNITY OF REVIEWING THIS JURY WAIVER WITH
LEGAL COUNSEL, AND THAT EACH KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL
RIGHTS.

         9.16.    Survival of Warranties and Certain Agreements. All agreements,
representations and warranties made herein shall survive the execution and
delivery of this Agreement, the making of the Loans, issuances of Letters of
Credit and the execution and delivery of the Notes. Notwithstanding anything in
this Agreement or implied by law to the contrary, the agreements of Borrowers
set forth in Sections 1.3(g), 1.9, 1.10, 1.11, 2.5 and 9.1 shall survive the
repayment of the Obligations and the termination of this Agreement.

         9.17.    Entire Agreement. This Agreement, the Notes and the other Loan
Documents embody the entire agreement among the parties hereto and supersede all
prior commitments, agreements, representations, and understandings, whether oral
or written, relating to the subject matter hereof, and may not be contradicted
or varied by evidence of prior, contemporaneous, or subsequent oral agreements
or discussions of the parties hereto. All Exhibits, Schedules and Annexes
referred to herein are incorporated in this Agreement by reference and
constitute a part of this Agreement.

         9.18.    Counterparts; Effectiveness. This Agreement and any
amendments, waivers, consents or supplements may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed and delivered shall be deemed an original, but all of
which counterparts together shall constitute but one in the same instrument.
This Agreement shall become effective upon the execution of a counterpart hereof
by each of the parties hereto.

         9.19.    Replacement of Lenders.

                  (a)      Within fifteen (15) days after receipt by Borrower
Representative of written notice and demand from any Lender for payment pursuant
to Section 1.10 or 1.11 or, as provided in this Section 9.19, in the case of
certain refusals by any Lender to consent to certain proposed amendments,
modifications, terminations or waivers with respect to this Agreement that have
been approved by Requisite Lenders, Supermajority Revolving Lenders or all
affected Lenders, as applicable (any such Lender demanding such payment or
refusing to so consent being referred to herein as an "Affected Lender"),
Borrowers may, at their option, notify Agent and such Affected Lender of its
intention to do one of the following:

                           (i)      Borrowers may obtain, at Borrowers' expense,
a replacement Lender ("Replacement Lender") for such Affected Lender, which
Replacement Lender shall be reasonably satisfactory to Agent. In the event
Borrowers obtain a Replacement Lender that will purchase all outstanding
Obligations owed to such Affected Lender and assume its Commitments hereunder
within ninety (90) days following notice of Borrowers' intention to do so, the
Affected Lender shall sell and assign all of its rights and delegate all of its
obligations under this Agreement to such Replacement Lender in accordance with
the provisions of Section 8.1, provided that Borrowers have reimbursed such

                                     - 65 -

<PAGE>

Affected Lender for any administrative fee payable pursuant to Section 8.1 and,
in any case where such replacement occurs as the result of a demand for payment
pursuant to Section 1.10 or 1.11, paid all amounts required to be paid to such
Affected Lender pursuant to Section 1.10 or 1.11 through the date of such sale
and assignment; or

                           (ii)     Borrowers may, with Agent's consent, prepay
in full all outstanding Obligations owed to such Affected Lender and terminate
such Affected Lender's Pro Rata Share of the Revolving Loan Commitment, in which
case the Revolving Loan Commitment will be reduced by the amount of such Pro
Rata Share. Borrowers shall, within ninety (90) days following notice of their
intention to do so, prepay in full all outstanding Obligations owed to such
Affected Lender (including, in any case where such prepayment occurs as the
result of a demand for payment for increased costs, such Affected Lender's
increased costs for which it is entitled to reimbursement under this Agreement
through the date of such prepayment), and terminate such Affected Lender's
obligations under the Revolving Loan Commitment.

                  (b)      In the case of a Non-Funding Lender pursuant to
Section 8.5(a), at Borrower Representative's request, Agent or a Person
acceptable to Agent shall have the right with Agent's consent and in Agent's
sole discretion (but shall have no obligation) to purchase from any Non-Funding
Lender, and each Non-Funding Lender agrees that it shall, at Agent's request,
sell and assign to Agent or such Person, all of the Loans and Commitments of
that Non-Funding Lender for an amount equal to the principal balance of all
Loans held by such Non-Funding Lender and all accrued interest and Fees with
respect thereto through the date of sale, such purchase and sale to be
consummated pursuant to an executed Assignment Agreement.

                  (c)      If, in connection with any proposed amendment,
modification, waiver or termination pursuant to Section 9.2 (a "Proposed
Change"):

                           (i)      requiring the consent of all affected
Lenders, the consent of Requisite Lenders is obtained, but the consent of other
Lenders whose consent is required is not obtained (any such Lender whose consent
is not obtained as described in this clause (i) and in clauses (ii) and (iii)
below being referred to as a "Non-Consenting Lender"),

                           (ii)     requiring the consent of Supermajority
Revolving Lenders, the consent of Requisite Lenders is obtained, but the consent
of Supermajority Revolving Lenders is not obtained,

                           (iii)    requiring the consent of Requisite Lenders,
the consent of Lenders holding 51% or more of the aggregate Commitments is
obtained, but the consent of Requisite Lenders is not obtained,

then, so long as Agent is not a Non-Consenting Lender, at Borrower
Representative's request Agent, or a Person reasonably acceptable to Agent,
shall have the right with Agent's consent and in Agent's sole discretion (but
shall have no obligation) to purchase from such Non-Consenting Lenders, and such
Non-Consenting Lenders agree that they shall, upon Agent's request, sell and
assign to Agent or such Person, all of the Loans and Commitments of such
Non-Consenting Lenders for an amount equal to the principal balance of all Loans
held by the Non-Consenting Lenders and all accrued interest and Fees with
respect thereto through the date of sale, such purchase and sale to be
consummated pursuant to an executed Assignment Agreement.

         9.20.    Delivery of Termination Statements and Mortgage Releases.

                  (a)      Upon payment in full in cash and performance of all
of the Obligations (other than indemnification Obligations), termination of the
Commitments and a release of all claims against Agent and Lenders, and so long
as no suits, actions proceedings, or claims are pending or threatened against
any Indemnitee asserting any damages, losses or liabilities that are indemnified
liabilities hereunder, Agent shall deliver to Borrower Representative
termination statements, mortgage releases and other documents necessary or
appropriate to evidence the termination of the Liens securing payment of the
Obligations.

                  (b)      Upon the disposition of any Collateral in accordance
with the terms and conditions provided herein, Agent shall deliver to Borrower
Representative termination statements, mortgage releases and other evidence
necessary or appropriate to evidence the termination of Liens on such
Collateral.

                  (c)      In the event that any Credit Party acquires any
Equipment and in connection therewith grants a security interest in such
Equipment to any Person providing purchase money financing to such Credit Party
for such Equipment and such security interest and financing does not contravene
any provision of this Agreement and prohibits the Lien of Agent therein, Agent,
at the request of such Credit Party shall release its security interest in such
Equipment or shall subordinate such Lien (as required by such Person) and shall
at the cost and expense of such Credit Party execute such documents as may be
necessary to release such Lien of record; provided, however, that upon any such
prohibition ceasing to be binding on such Credit Party, the Lien of Agent in
such Equipment shall automatically be reinstated and such Credit Party shall
immediately notify Agent and shall take all steps as may be necessary to perfect
such Lien of Agent within 20 Business Days following such prohibition ceasing to
be effective.

         9.21.    Subordination of Intercompany Debt.

                  (a)      Each Credit Party hereby agrees that any intercompany
Indebtedness or other intercompany payables or receivables, or intercompany
advances directly or indirectly made by or owed to such Credit Party by any
other Credit Party (collectively, "Intercompany Debt"), of whatever nature at
any time outstanding shall be subordinate and subject in right of payment to the
prior payment in full in cash of the Obligations. Each Credit Party hereby
agrees that it will not, while any Event of Default is continuing, accept any
payment, including by offset, on any Intercompany Debt until the Termination
Date, in each case, except with the prior written consent of Agent.

                  (b)      In the event that any payment on any Intercomapny
Debt shall be received by a Credit Party other than as permitted by this Section
9.21 before the Termination Date, such Credit Party shall receive such payments
and hold the same in trust for, segregate the same from its own assets and shall
immediately pay over to, the Agent for the benefit of the Agent and Lenders all
such sums to the extent necessary so that Agent and the Lenders shall have been
paid in full, in cash, all Obligations owed or which may become owing.

                  (c)      Upon any payment or distribution of any assets of any
Credit Party of any kind or character, whether in cash, property or securities
by set-off, recoupment or otherwise, to creditors in any liquidation or other
winding-up of such Credit Party or in the event of any Proceeding, Agent and
Lenders shall first be entitled to receive payment in full in cash, in
accordance with the terms of the Obligations and of this Agreement, of all
amounts payable under or in respect of such Obligations, before any payment or
distribution is made on, or in respect of, any Intercompany Debt, in any such
Proceeding, any distribution or payment, to which Agent or any Lender would be
entitled except for the provisions hereof shall be paid by such Credit Party, or
by any receiver, trustee in bankruptcy, liquidating trustee, agent or other
person making such payment or distribution directly to Agent (for the benefit of
Agent and the Lenders) to the extent necessary to pay all such Obligations in
full in cash, after giving effect to any concurrent payment or distribution to
Agent and Lenders (or to Agent for the benefit of Agent and Lenders).

                                   SECTION 10.

                                 CROSS-GUARANTY

         10.1.    Cross-Guaranty. Each Borrower hereby agrees that such Borrower
is jointly and severally liable for, and hereby absolutely and unconditionally
guarantees to Agent and Lenders and their respective successors and assigns, the
full and prompt payment (whether at stated maturity, by acceleration or
otherwise) and performance of, all Obligations owed or hereafter owing to Agent
and Lenders by each other Borrower. Each Borrower agrees that its guaranty
obligation hereunder is a continuing guaranty of payment and performance and not
of collection, that its obligations under this Section 10 shall not be
discharged until payment and performance, in full, of the Obligations has
occurred, and that its obligations under this Section 10 shall be absolute and
unconditional, irrespective of, and unaffected by:

                  (a)      the genuineness, validity, regularity, enforceability
or any future amendment of, or change in, this Agreement, any other Loan
Document or any other agreement, document or instrument to which any Borrower is
or may become a party;

                  (b)      the absence of any action to enforce this Agreement
(including this Section 10) or any other Loan Document or the waiver or consent
by Agent and Lenders with respect to any of the provisions thereof;

                  (c)      the existence, value or condition of, or failure to
perfect its Lien against, any security for the Obligations or any action, or the
absence of any action, by Agent and Lenders in respect thereof (including the
release of any such security);

                  (d)      the insolvency of any Credit Party; or

                  (e)      any other action or circumstances that might
otherwise constitute a legal or equitable discharge or defense of a surety or
guarantor.

Each Borrower shall be regarded, and shall be in the same position, as principal
debtor with respect to the Obligations guaranteed hereunder.

         10.2.    Waivers by Borrowers. Each Borrower expressly waives all
rights it may have now or in the future under any statute, or at common law, or
at law or in equity, or otherwise, to compel Agent or Lenders to marshal assets
or to proceed in respect of the Obligations guaranteed hereunder against any
other Credit Party, any other party or against any security for the payment and
performance of the Obligations before proceeding against, or as a condition to
proceeding against, such Borrower. It is agreed among each Borrower, Agent and
Lenders that the foregoing waivers are of the essence of the transaction
contemplated by this Agreement and the other Loan Documents and that, but for
the provisions of this Section 10 and such waivers, Agent and Lenders would
decline to enter into this Agreement.

         10.3.    Benefit of Guaranty. Each Borrower agrees that the provisions
of this Section 10 are for the benefit of Agent and Lenders and their respective
successors, transferees, endorsees and assigns, and nothing herein contained
shall impair, as between any other Borrower and Agent or Lenders, the
obligations of such other Borrower under the Loan Documents.

                                     - 68 -

<PAGE>

         10.4.    Waiver of Subrogation, Etc. Notwithstanding anything to the
contrary in this Agreement or in any other Loan Document, and except as set
forth in Section 10.7, each Borrower hereby expressly and irrevocably waives
until the Termination Date any and all rights at law or in equity to
subrogation, reimbursement, exoneration, contribution, indemnification or set
off and any and all defenses available to a surety, guarantor or accommodation
co-obligor. Each Borrower acknowledges and agrees that this waiver is intended
to benefit Agent and Lenders and shall not limit or otherwise affect such
Borrower's liability hereunder or the enforceability of this Section 10, and
that Agent, Lenders and their respective successors and assigns are intended
third party beneficiaries of the waivers and agreements set forth in this
Section 10.4 and their rights under this Section 10.4 shall survive payment in
full of the Obligations. The foregoing waiver shall not be deemed to limit or
prohibit the payment of indebtedness or other obligations of any Borrower to any
other Borrower or other Person which is incurred in the ordinary course of
business and which is otherwise permitted under this Agreement or any other Loan
Document.

         10.5.    Election of Remedies. If Agent or any Lender may, under
applicable law, proceed to realize its benefits under any of the Loan Documents
giving Agent or such Lender a Lien upon any Collateral, whether owned by any
Borrower or by any other Person, either by judicial foreclosure or by
non-judicial sale or enforcement, Agent or any Lender may, at its sole option,
determine which of its remedies or rights it may pursue without affecting any of
its rights and remedies under this Section 10. If, in the exercise of any of its
rights and remedies, Agent or any Lender shall forfeit any of its rights or
remedies, including its right to enter a deficiency judgment against any
Borrower or any other Person, whether because of any applicable laws pertaining
to "election of remedies" or the like, each Borrower hereby consents to such
action by Agent or such Lender and waives any claim based upon such action, even
if such action by Agent or such Lender shall result in a full or partial loss of
any rights of subrogation that each Borrower might otherwise have had but for
such action by Agent or such Lender. Any election of remedies that results in
the denial or impairment of the right of Agent or any Lender to seek a
deficiency judgment against any Borrower shall not impair any other Borrower's
obligation to pay the full amount of the Obligations. In the event Agent or any
Lender shall bid at any foreclosure or trustee's sale or at any private sale
permitted by law or the Loan Documents, Agent or such Lender may bid all or less
than the amount of the Obligations and the amount of such bid need not be paid
by Agent or such Lender but shall be credited against the Obligations. The
amount of the successful bid at any such public sale, whether Agent, Lender or
any other party is the successful bidder, shall be conclusively deemed to be the
fair market value of the Collateral and the difference between such bid amount
and the remaining balance of the Obligations shall be conclusively deemed to be
the amount of the Obligations guaranteed under this Section 10, notwithstanding
that any present or future law or court decision or ruling may have the effect
of reducing the amount of any deficiency claim to which Agent or any Lender
might otherwise be entitled but for such bidding at any such sale.

         10.6.    Limitation. Notwithstanding any provision herein contained to
the contrary, each Borrower's liability under this Section 10 (which liability
is in any event in addition to amounts for which such Borrower is primarily
liable under Section 1) shall be limited to an amount not to exceed as of any
date of determination the greater of:

                  (a)      the net amount of all Loans advanced to any other
Borrower under this Agreement and then re-loaned or otherwise transferred to, or
for the benefit of, such Borrower; and

                  (b)      the amount that could be claimed by Agent and Lenders
from such Borrower under this Section 10 without rendering such claim voidable
or avoidable under Section 548 of Chapter 11 of the Bankruptcy Code or under any
applicable state Uniform Fraudulent Transfer Act, Uniform Fraudulent Conveyance
Act or similar statute or common law after taking into account, among other
things, such Borrower's right of contribution and indemnification from each
other Borrower under Section 10.7.

                                     - 69 -

<PAGE>

         10.7.    Contribution with Respect to Guaranty Obligations.

                  (a)      To the extent that any Borrower shall make a payment
under this Section 10 of all or any of the Obligations (other than Loans made to
that Borrower for which it is primarily liable) (a "Guarantor Payment") that,
taking into account all other Guarantor Payments then previously or concurrently
made by any other Borrower, exceeds the amount that such Borrower would
otherwise have paid if each Borrower had paid the aggregate Obligations
satisfied by such Guarantor Payment in the same proportion that such Borrower's
"Allocable Amount" (as defined below) (as determined immediately prior to such
Guarantor Payment) bore to the aggregate Allocable Amounts of each of the
Borrowers as determined immediately prior to the making of such Guarantor
Payment, then, following indefeasible payment in full in cash of the Obligations
and termination of the Commitments, such Borrower shall be entitled to receive
contribution and indemnification payments from, and be reimbursed by, each other
Borrower for the amount of such excess, pro rata based upon their respective
Allocable Amounts in effect immediately prior to such Guarantor Payment.

                  (b)      As of any date of determination, the "Allocable
Amount" of any Borrower shall be equal to the maximum amount of the claim that
could then be recovered from such Borrower under this Section 10 without
rendering such claim voidable or avoidable under Section 548 of Chapter 11 of
the Bankruptcy Code or under any applicable state Uniform Fraudulent Transfer
Act, Uniform Fraudulent Conveyance Act or similar statute or common law.

                  (c)      This Section 10.7 is intended only to define the
relative rights of Borrowers and nothing set forth in this Section 10.7 is
intended to or shall impair the obligations of Borrowers, jointly and severally,
to pay any amounts as and when the same shall become due and payable in
accordance with the terms of this Agreement, including Section 10.1. Nothing
contained in this Section 10.7 shall limit the liability of any Borrower to pay
the Loans made directly or indirectly to that Borrower and accrued interest,
Fees and expenses with respect thereto for which such Borrower shall be
primarily liable.

                  (d)      The parties hereto acknowledge that the rights of
contribution and indemnification hereunder shall constitute assets of the
Borrower to which such contribution and indemnification is owing.

                  (e)      The rights of the indemnifying Borrowers against
other Credit Parties under this Section 10.7 shall be exercisable upon the full
and indefeasible payment of the Obligations and the termination of the
Commitments.

         10.8.    Liability Cumulative. The liability of Borrowers under this
Section 10 is in addition to and shall be cumulative with all liabilities of
each Borrower to Agent and Lenders under this Agreement and the other Loan
Documents to which such Borrower is a party or in respect of any Obligations or
obligation of the other Borrower, without any limitation as to amount, unless
the instrument or agreement evidencing or creating such other liability
specifically provides to the contrary.

other right, power, or privilege. All rights and remedies existing under this
Agreement are cumulative with, and not exclusive of, any rights or remedies
otherwise available.

                security interest shall be granted under this Agreement in such
                Equipment unless and until such prohibition ceases to be binding

                pledge, for the account of such Grantor, or as to which such
                Grantor may have any right or power.

3.          AGENT'S AND LENDERS' RIGHTS:  LIMITATIONS ON AGENT'S AND LENDERS'
            OBLIGATIONS

            (a) It is expressly agreed by each Grantor that, anything herein or
                in any other Loan Document to the contrary notwithstanding, each
                Grantor shall remain liable under each of its respective
                Contractual Obligations, including all Licenses, to observe and
                perform all the conditions and obligations to be observed and
                performed by it thereunder. Neither Agent nor any Lender shall
                have any obligation or liability under any Contractual
                Obligation by reason of or arising out of this Agreement or any
                other Loan Document or the granting herein of a Lien thereon or
                the receipt by Agent or any Lender of any payment relating to
                any Contractual Obligation pursuant hereto. Neither Agent nor
                any Lender shall be required or obligated in any manner to
                perform or fulfill any of the obligations of any Grantor under
                or pursuant to any Contractual Obligation, or to make any
                payment, or to make any inquiry as to the nature or the
                sufficiency of any payment received by it or the sufficiency of
                any performance by any party under any Contractual Obligation,
                or to present or file any claims, or to take any action to
                collect or enforce any performance or the payment of any amounts
                which may have been assigned to it or to which it may be
                entitled at any time or times.

            (b) Agent may at any time after an Event of Default has occurred and
                is continuing (or if any rights of set-off (other than set-offs
                against an Account arising under the Contract giving rise to the
                same Account) or contra accounts may be asserted with respect to
                the following), without prior notice to any Grantor, notify each
                Grantor's Account Debtors and all other Persons obligated on any
                of the Collateral that Agent has a security interest therein,
                and that payments shall be made directly to Agent, for itself
                and the benefit of Lenders. Upon the request of Agent, each
                Grantor shall so notify its Account Debtors and other Persons
                obligated on the Collateral. Once any such notice has been given
                to any Account Debtor or other Person obligated on the
                Collateral, none of the Grantors shall give any contrary
                instructions to such Account Debtor or other Person without
                Agent's prior written consent.

                                      -4-
<PAGE>

            (c) Agent may at any time in Agent's own name, in the name of a
                nominee of Agent or in the name of any Grantor communicate (by
                mail, telephone, facsimile or otherwise) with Account Debtors,
                parties to Contractual Obligations and obligors in respect of
                Instruments to verify with such Persons, to Agent's
                satisfaction, the existence, amount, terms of, and any other
                matter relating to, Accounts, Instruments, Chattel Paper and/or
                payment intangibles; provided, that if no Event of Default has
                occurred and is continuing, Agent shall only use a nominee name
                for such communication. If an Event of Default shall have
                occurred and be continuing, each Grantor, at its own expense,
                shall cause the independent certified public accountants then
                engaged by such Grantor to prepare and deliver to Agent and each
                Lender at any time and from time to time promptly upon Agent's
                request the following reports with respect to such Grantor: (i)
                a reconciliation of all Accounts; (ii) an aging of all Accounts;
                (iii) trial balances; and (iv) a test verification of such
                Accounts as Agent may request. Each Grantor, at its own expense,
                shall deliver to Agent the results of each physical
                verification, if any, which such Grantor may in its discretion
                have made, or caused any other Person to have made on its
                behalf, of all or any portion of its Inventory.

4.          REPRESENTATIONS AND WARRANTIES

            Each Grantor, jointly and severally, represents and warrants that:

            (a) Each Grantor has rights in and the power to transfer each item
                of the Collateral upon which it purports to grant a Lien
                hereunder free and clear of any and all Liens other than
                Permitted Encumbrances.

            (b) No effective security agreement, financing statement, equivalent
                security or Lien instrument or continuation statement covering

                       transfer executed in blank) promptly after such Credit
                       Party receives the same. Upon acquiring any negotiable
                       Documents, certificated securities, Chattel Paper or
                       Instruments (including any Intercompany Notes but
                       excluding written lease agreements governing Short-Term
                       Rentals), in each case in excess of $250,000, such
                       Grantor will provide prompt written notice thereof to
                       Agent.

                (iv)   Such Grantor shall, in accordance with the terms of the
                       Credit Agreement, obtain waivers or subordinations of
                       Liens from landlords, bailees and mortgagees, and such
                       Grantor shall in all instances obtain signed
                       acknowledgements of Agent's Liens from bailees having
                       possession of such Grantor's Goods that they hold for the
                       benefit of Agent.

                (v)    To the extent required by Agent, such Grantor shall
                       obtain authenticated control letters in form and

                       intermediary, or commodities intermediary issuing or
                       holding any financial assets or commodities to or for
                       such Grantor. Agent shall not terminate such Grantor's
                       access to any such financial assets or commodities except
                       during the continuation of an Event of Default.

                (vi)   As required by Section 6 of this Agreement, and in
                       accordance with Section 2.10 of the Credit Agreement,
                       such Grantor shall obtain a blocked account, lockbox or

                       holding a Deposit Account for such Grantor.

                (vii)  If such Grantor is or becomes the beneficiary of a letter
                       of credit, such Grantor shall promptly, and in any event
                       within two (2) Business Days after becoming a
                       beneficiary, notify Agent thereof and enter into a
                       tri-party agreement with Agent and the issuer and/or
                       confirmation bank with respect to Letter-of-Credit Rights
                       assigning such Letter-of-Credit Rights to Agent and
                       directing all payments thereunder to the Agent's account
                       identified in Section 1.4 of the Credit Agreement, all in
                       form and substance reasonably satisfactory to Agent.

                (viii) Such Grantor shall take all steps necessary to grant
                       Agent control of all electronic Chattel Paper in
                       accordance with the Code and all "transferable records"
                       as defined in each of the Uniform Electronic Transactions
                       Act and the Electronic Signatures in Global and National
                       Commerce Act.

                (ix)   Such Grantor hereby irrevocably authorizes Agent at any
                       time and from time to time to file in any filing office
                       in any Uniform Commercial Code jurisdiction any initial
                       financing statements and amendments thereto that (a)
                       indicate the Collateral (i) as all assets of such Grantor
                       or words of similar effect, regardless of whether any
                       particular asset comprised in the Collateral falls within
                       the scope of Article 9 of the Code or such jurisdiction,
                       or (ii) as being of an equal or lesser scope or with
                       greater detail, and (b) contain any other information
                       required by part 5 of Article 9 of the Code for the
                       sufficiency or filing office acceptance of any financing
                       statement or amendment, including (i) whether such
                       Grantor is an organization, the type of organization and
                       any organization identification number issued to such
                       Grantor, and (ii) in the case of a financing statement
                       filed as a fixture filing or indicating Collateral as
                       as-extracted collateral or timber to be cut, a sufficient
                       description of real property to which the Collateral
                       relates. Such Grantor agrees to furnish any such
                       information to Agent promptly upon request. Such Grantor
                       also hereby ratifies its authorization for Agent to have
                       filed in any Uniform Commercial Code jurisdiction any
                       initial financing statements or amendments thereto if
                       filed prior to the date hereof.

                (x)    Such Grantor shall promptly, and in any event within two
                       (2) Business Days after the same is acquired by it,
                       notify Agent of any Commercial Tort Claim (as defined in
                       the Code) acquired by it and unless otherwise consented
                       by Agent (which consent may be revoked), such Grantor
                       shall enter into a supplement to this Agreement, granting
                       to Agent a Lien in such commercial tort claim.

            (b) Maintenance of Records. Such Grantor shall keep and maintain, at
                its own cost and expense, satisfactory and complete records of
                the Collateral, including a record of any and all payments
                received and any and all credits granted with respect to the
                Collateral and all other dealings with the Collateral. Such
                Grantor shall mark its books and records pertaining to the
                Collateral to evidence this Agreement and the Liens granted
                hereby. If any Grantor retains possession of any Chattel Paper
                or Instruments (including Intercompany Notes but excluding
                written lease agreements governing Short-Term Rentals) with
                Agent's consent, such Chattel Paper and Instruments (including
                Intercompany Notes but excluding written lease agreements
                governing Short-Term Rentals) shall be marked with the following
                legend: "This writing and the obligations

                evidenced or secured hereby are subject to the security interest
                of General Electric Capital Corporation, as Agent, for the
                benefit of Agent and certain Lenders."

            (c) Covenants Regarding Patent, Trademark and Copyright Collateral.

                (i)    Such Grantor shall notify Agent immediately if it knows
                       or has reason to know that any application or
                       registration relating to any Patent, Trademark or
                       Copyright (now or hereafter existing) may become
                       abandoned or dedicated, or of any adverse determination
                       or development (including the institution of, or any such
                       determination or development in, any proceeding in the
                       United States Patent and Trademark Office, the United
                       States Copyright Office or any court) regarding such
                       Grantor's ownership of any Patent, Trademark or
                       Copyright, its right to register the same, or to keep and
                       maintain the same.

                (ii)   In no event shall such Grantor, either directly or
                       through any agent, employee, licensee or designee, file
                       an application for the registration of any Patent,
                       Trademark or Copyright with the United States Patent and
                       Trademark Office, the United States Copyright Office or
                       any similar office or agency without giving Agent prior
                       written notice thereof, and, upon request of Agent, such
                       Grantor shall execute and deliver any and all Patent
                       Security Agreements, Copyright Security Agreements or
                       Trademark Security Agreements as Agent may reasonably
                       request to evidence Agent's Lien on such Patent,
                       Trademark or Copyright, and the General Intangibles of
                       such Grantor relating thereto or represented thereby.

                (iii)  Such Grantor shall take all actions necessary or
                       reasonably requested by Agent to maintain and pursue (and
                       not abandon) each application, to obtain the relevant
                       registration and to maintain the registration of each of
                       the Patents, Trademarks and Copyrights (now or hereafter
                       existing), including the filing of applications for
                       renewal, affidavits of use, affidavits of
                       noncontestability and opposition and interference and
                       cancellation proceedings, unless such Grantor shall
                       determine that such Patent, Trademark or Copyright is not
                       material to the conduct of its business.

                (iv)   In the event Grantor learns that any of the Patent,
                       Trademark or Copyright Collateral is infringed upon, or
                       misappropriated or diluted by a third party, each Grantor
                       shall comply with Section 5(a)(ix) of this Agreement.
                       Such Grantor shall, unless it shall reasonably determine
                       that such infringement, misappropriation or dilution of
                       Patent, Trademark or Copyright Collateral is not material
                       to the conduct of its business or operations, promptly
                       sue for infringement, misappropriation or dilution and to
                       recover any and all damages for such infringement,
                       misappropriation or dilution, and shall take such other
                       actions as Agent shall deem appropriate under the
                       circumstances to protect such Patent, Trademark or
                       Copyright Collateral.

            (d) Indemnification. In any suit, proceeding or action brought by
                Agent or any Lender relating to any Collateral for any sum owing
                with respect thereto or to enforce any rights or claims with
                respect thereto, such Grantor will save, indemnify and keep
                Agent and Lenders harmless from and against all expense
                (including reasonable attorneys' fees and expenses), loss or
                damage suffered by reason of any defense, set-off, counterclaim,
                recoupment or reduction of liability whatsoever of its Account
                Debtors or other Person obligated on the Collateral, arising out
                of a breach by such Grantor of any obligation

                                      -11-
<PAGE>

                thereunder or arising out of any other agreement, indebtedness
                or liability at any time owing to, or in favor of, such obligor
                or its successors from such Grantor, except in the case of Agent
                or any Lender, to the extent such expense, loss, or damage is
                attributable solely to the gross negligence or willful
                misconduct of Agent or such Lender as finally determined by a
                court of competent jurisdiction. All such obligations of each
                Grantor shall be and remain enforceable against and only against
                such Grantor and shall not be enforceable against Agent or any
                Lender.

            (e) Compliance with Terms of Accounts, etc. In all material
                respects, such Grantor will perform and comply with all
                obligations in respect of the Collateral and all other
                agreements to which it is a party or by which it is bound
                relating to the Collateral.

            (f) Limitation on Liens on Collateral. Such Grantor will not create,
                permit or suffer to exist, and will defend the Collateral
                against, and take such other action as is necessary to remove,
                any Lien on any of the Collateral except Permitted Encumbrances,
                and will defend the right, title and interest of Agent and
                Lenders in and to any of such Grantor's rights under the
                Collateral against the claims and demands of all Persons
                whomsoever, except claims pursuant to the Permitted
                Encumbrances.

            (g) Limitations on Disposition. Such Grantor will not sell, license,
                lease, transfer or otherwise dispose of any of the Collateral,
                or attempt or contract to do so except as permitted by this
                Agreement or the Credit Agreement.

            (h) Further Identification of Collateral. Such Grantor will, if so
                requested by Agent, furnish to Agent, as often as Agent
                reasonably requests, statements and schedules further
                identifying and describing the Collateral and such other reports
                in connection with the Collateral as Agent may reasonably
                request, all in such detail as Agent may reasonably specify.
                Grantor shall promptly notify Agent in writing upon acquiring
                any interest hereafter in property that is of a type where a
                security interest or Lien must be or may be registered, recorded
                or filed under, or notice thereof given under, any federal
                statute or regulation and that is not already covered by this
                Agreement.

            (i) Notices. Such Grantor will advise Agent promptly, in reasonable
                detail (i) of any Lien (other than Permitted Encumbrances) or
                claim made or asserted against any of the Collateral, and (ii)
                of the occurrence of any other event which could reasonably be
                expected to have a Material Adverse Effect on the aggregate
                value of the Collateral or on the Liens created hereunder or
                under any other Loan Document.

            (j) Good Standing Certificates. If and whenever requested by Agent,
                such Grantor shall provide to Agent a certificate of good
                standing from its state of incorporation or organization.

            (k) Organizational/Collateral Location Changes; No Reincorporation.
                Such Grantor will give Agent at least thirty (30) days prior
                written notice of any change required to be made to Schedule
                IIIA, Schedule IIIB, Schedule IIIC, Schedule IIID or Schedule
                IIIE. Without limiting the prohibitions on mergers involving any
                Grantor as contained in the Credit Agreement, none of the
                Grantors shall reincorporate or reorganize itself under the laws
                of any jurisdiction other than the jurisdiction in which it is
                incorporated or organized as of the date hereof without the
                prior written consent of Agent.

                                      -12-
<PAGE>

            (l) Terminations; Amendments Not Authorized. Such Grantor
                acknowledges that it is not authorized to file any financing
                statement or amendment or termination statement with respect to
                any financing statement filed in favor of Agent without the
                prior written consent of Agent and agrees that it will not do so
                without the prior written consent of Agent, subject to such
                Grantor's rights under Section 9-509(d)(2) of the Code.

            (m) Authorized Terminations. Agent will promptly deliver to such
                Grantor for filing or authorize such Grantor to prepare and file
                termination statements and releases in accordance with Section
                9.20 of the Credit Agreement.

6.          BANK ACCOUNTS; COLLECTION OF ACCOUNTS AND PAYMENTS

            Within the time periods specified in the Credit Agreement, each
            Grantor shall enter into a bank agency and control agreement ("Bank
            Agency and Control Agreement"), in a form specified by Agent, with
            each financial institution with which each Grantor maintains from
            time to time any Deposit Account. Each Bank Agency and Control
            Agreement shall provide, among other things, that (a) all items of
            payment deposited in each Deposit Account subject thereto shall be
            held by the applicable financial institution as Agent or
            bailee-in-possession for Agent, on behalf of itself and Lenders, (b)
            the financial institution executing such agreement has no rights of
            offset or recoupment of any other claim against any Deposit Account
            subject thereto, as the case may be, other than for payment of its
            services and other charges directly related to the administration of
            each such Deposit Account and for returned checks or other items of
            payment, and (c) to the extent provided below, the financial
            institution will transfer all amounts held or deposited from time to
            time in any such Deposit Account as Agent may so direct. Each
            Grantor hereby grants to Agent, for the benefit of Agent and
            Lenders, a continuing lien upon, and security interest in, all such
            accounts and all funds at any time paid, deposited, credited or held
            in such accounts (whether for collection, provisionally or
            otherwise) or otherwise in the possession of such financial
            institutions, and each such financial institution shall act as
            Agent's agent in connection therewith. No Grantor shall establish
            any Deposit Account with any financial institution unless prior
            thereto Agent and such Grantor shall have entered into a Bank Agency
            and Control Agreement satisfactory to Agent with such financial
            institution.

            To the extent requested by the Agent, each Grantor shall establish a
            lockbox account ("Lockbox Account") and blocked accounts
            (collectively, "Blocked Accounts") in such Grantor's name with such
            banks as are reasonably acceptable to Agent ("Collecting Banks"),
            subject to a Bank Agency and Control Agreement pursuant to which all
            Account Debtors shall directly remit all payments on Accounts and in
            which each Grantor will immediately deposit all cash payments
            constituting proceeds of Collateral in the identical form in which
            such payment was made, whether by cash or check. All payments
            received in the lockboxes shall promptly, subject to Section 6.5 of
            the Credit Agreement, (i) first, be applied to the outstanding
            Obligations other than Letter of Credit Obligations, until paid in
            full and (ii) second, following such payment in full, be remitted to
            the Grantors. In addition, Agent, for the benefit of Agent and
            Lenders, may establish one or more depository accounts at each
            Collecting Bank or at a centrally located bank in the name of Agent
            or any one or more Grantors as customer (collectively, the
            "Concentration Accounts"). From and after receipt by any Collecting
            Bank of written notice from Agent to such Collecting Bank that an
            Event of Default has occurred and is continuing, all amounts held or
            deposited from time to time in the Blocked Accounts held by such
            Collecting Bank shall be transferred on a daily basis to Agent (as
            Agent may direct) or any of the Concentration Accounts; provided,
            that whether or not an Event of Default is continuing all accounts
            credited to the Lockbox Account shall be transferred to Agent's
            account on a daily basis. Subject to the foregoing, each Grantor
            hereby agrees that all payments received by Agent or any Lender
            whether by cash, check, wire transfer

                                      -13-
<PAGE>

            or any other instrument, made to such Blocked Accounts, Lockbox
            Account or Concentration Accounts or otherwise received by Agent or
            any Lender and whether on the Accounts or as proceeds of other
            Collateral or otherwise will be the sole and exclusive property of
            Lenders. Each Grantor, and any of its Affiliates, employees, agents
            and other Persons acting for or in concert with such Grantor shall,
            acting as trustee for Agent and Lenders, receive, as the sole and
            exclusive property of Lenders, any moneys, checks, notes, drafts or
            other payments relating to and/or constituting proceeds of Accounts
            or other Collateral which come into the possession or under the
            control of such Grantor or any Affiliates, employees, agent, or
            other Persons acting for or in concert with such Grantor, and
            immediately upon receipt thereof, such Grantor or such Persons shall
            deposit the same or cause the same to be deposited in kind, in a
            Blocked Account or other account subject to a Bank Agency and
            Control Agreement.

            If at any time a Collecting Bank is obligated to transfer to Agent
            or any Concentration Account all amounts held or deposited in the
            Blocked Accounts held by such Collecting Bank, no Grantor shall, and
            no Grantor shall permit any Subsidiary to, accumulate or maintain
            cash in any disbursement or payroll account, as of any date, in an
            amount in excess of checks outstanding against such account as of
            such date and amounts necessary to meet minimum balance
            requirements.

            Each Grantor shall close each of its deposit accounts (and promptly
            establish replacement deposit accounts with a financial institution
            which has executed, or is willing to execute, a Bank Agency and
            Control Agreement) maintained with any financial institution which
            is the subject of a notice from Agent that the creditworthiness of
            such financial institution or any of its affiliates is no longer
            acceptable to Agent, or that the operating performance, funds
            transfer or availability procedures or performance with respect to
            any Bank Agency and Control Agreement of such financial institution
            is no longer acceptable in Agent's reasonable judgment.

7.          AGENT'S APPOINTMENT AS ATTORNEY-IN-FACT

            On the Closing Date each Grantor shall execute and deliver to Agent
            a power of attorney (the "Power of Attorney") substantially in the
            form attached hereto as Exhibit A. The power of attorney granted
            pursuant to the Power of Attorney is a power coupled with an
            interest and shall be irrevocable until the Termination Date. The
            powers conferred on Agent, for the benefit of Agent and Lenders,
            under the Power of Attorney are solely to protect Agent's interests
            (for the benefit of Agent and Lenders) in the Collateral and shall
            not impose any duty upon Agent or any Lender to exercise any such
            powers. Agent agrees that (a) except for the powers granted in
            clause (h) of the Power of Attorney, it shall not exercise any power
            or authority granted under the Power of Attorney unless an Event of
            Default has occurred and is continuing, and (b) Agent shall account
            for any moneys received by Agent in respect of any foreclosure on or
            disposition of Collateral pursuant to the Power of Attorney provided
            that none of Agent nor any Lender shall have any duty as to any
            Collateral, and Agent and Lenders shall be accountable only for
            amounts they actually receive as a result of the exercise of such
            powers. NONE OF AGENT, LENDERS OR THEIR RESPECTIVE AFFILIATES,
            OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR REPRESENTATIVES SHALL BE
            RESPONSIBLE TO ANY GRANTOR FOR ANY ACT OR FAILURE TO ACT UNDER ANY
            POWER OF ATTORNEY OR OTHERWISE, EXCEPT IN RESPECT OF DAMAGES
            ATTRIBUTABLE SOLELY TO THEIR OWN GROSS NEGLIGENCE OR WILLFUL
            MISCONDUCT AS FINALLY DETERMINED BY A COURT OF COMPETENT
            JURISDICTION, NOR FOR ANY PUNITIVE, EXEMPLARY, INDIRECT OR
            CONSEQUENTIAL DAMAGES.

8.          REMEDIES:  RIGHTS UPON DEFAULT

            (a) In addition to all other rights and remedies granted to it under
                this Agreement, the Credit Agreement, the other Loan Documents
                and under any other instrument or agreement securing, evidencing
                or relating to any of the Obligations, if any Event of Default
                shall have occurred and be continuing, Agent may exercise all
                rights and remedies of a secured party under the Code. Without
                limiting the generality of the foregoing, each Grantor expressly
                agrees that in any such event Agent, without demand of
                performance or other demand, advertisement or notice of any kind
                (except the notice specified below of time and place of public
                or private sale) to or upon any Grantor or any other Person (all
                and each of which demands, advertisements and notices are hereby
                expressly waived to the maximum extent permitted by the Code and
                other applicable law), may forthwith (personally or through its
                agents) enter upon the premises where any Collateral is located
                through self-help, without judicial process, without first
                obtaining a final judgment or giving any Grantor or any other
                Person notice and opportunity for a hearing on Agent's claim or
                action and may take possession of, collect, receive, assemble,
                process, appropriate, remove and realize upon the Collateral, or
                any part thereof, and may forthwith sell, lease, license,
                assign, give an option or options to purchase, or sell or
                otherwise dispose of and deliver said Collateral (or contract to
                do so), or any part thereof, in one or more parcels at a public
                or private sale or sales, at any exchange at such prices as it
                may deem acceptable, for cash or on credit or for future
                delivery without assumption of any credit risk. Agent or any
                Lender shall have the right upon any such public sale or sales
                and, to the extent permitted by law, upon any such private sale
                or sales, to purchase for the benefit of Agent and Lenders, the
                whole or any part of said Collateral so sold, free of any right
                or equity of redemption, which equity of redemption each Grantor
                hereby releases. Such sales may be adjourned and continued from
                time to time with or without notice. Agent shall have the right
                to conduct such sales on each Grantor's premises or elsewhere
                and shall have the right to use each Grantor's premises without
                charge for such time or times as Agent deems necessary or
                advisable.

                If any Event of Default shall have occurred and be continuing,
                each Grantor further agrees, at Agent's request, to assemble the
                Collateral and make it available to Agent at a place or places
                designated by Agent which are reasonably convenient to Agent and
                such Grantor, whether at such Grantor's premises or elsewhere.
                Without limiting the foregoing, Agent shall also have the right
                to require that each Grantor store and keep any Collateral
                pending further action by Agent, and while Collateral is so
                stored or kept, provide such guards and maintenance services as
                shall be necessary to protect the same and to preserve and
                maintain Collateral in good condition. Until Agent is able to
                effect a sale, lease, license or other disposition of
                Collateral, Agent shall have the right to hold or use
                Collateral, or any part thereof, to the extent that it deems
                appropriate for the purpose of preserving Collateral or its
                value or for any other purpose deemed appropriate by Agent.
                Agent shall not have any obligation to any Grantor to maintain
                or preserve the rights of any Grantor as against third parties
                with respect to Collateral while Collateral is in the possession
                of Agent. Agent may, if it so elects, seek the appointment of a
                receiver or keeper to take possession of Collateral and to
                enforce any of Agent's remedies (for the benefit of Agent and
                Lenders), with respect to such appointment without prior notice
                or hearing as to such appointment. Agent shall apply the net
                proceeds of any such collection, recovery, receipt,
                appropriation, realization or sale to the Obligations as
                provided in the Credit Agreement, and only after so paying over
                such net proceeds, and after the payment by Agent of any other
                amount required by any provision of law, need Agent account for
                the surplus, if any, to any Grantor. To the maximum extent
                permitted

                                      -15-
<PAGE>

                by applicable law, each Grantor waives all claims, damages, and
                demands against Agent or any Lender arising out of the
                repossession, retention or sale of the Collateral except such as
                arise solely out of the gross negligence or willful misconduct
                of Agent or such Lender as finally determined by a court of
                competent jurisdiction. Each Grantor agrees that ten (10) days
                prior notice by Agent of the time and place of any public sale
                or of the time after which a private sale may take place is
                reasonable notification of such matters. Notwithstanding any
                such notice of sale, Agent shall not be obligated to make any
                sale of Collateral. In connection with any sale, lease, license
                or other disposition of Collateral, Agent may disclaim any
                warranties that might arise in connection therewith and Agent
                shall have no obligation to provide any warranties at such time.
                Each Grantor shall remain liable for any deficiency if the
                proceeds of any sale or disposition of the Collateral are
                insufficient to pay all Obligations, including any attorneys'
                fees or other expenses incurred by Agent or any Lender to
                collect such deficiency.

            (b) Except as otherwise specifically provided herein, each Grantor
                hereby waives presentment, demand, protest or any notice (to the
                maximum extent permitted by applicable law) of any kind in
                connection with this Agreement or any Collateral.

            (c) To the extent that applicable law imposes duties on Agent to
                exercise remedies in a commercially reasonable manner, each
                Grantor acknowledges and agrees that it is not commercially
                unreasonable for Agent (i) to fail to incur expenses reasonably
                deemed significant by Agent to prepare Collateral for
                disposition or otherwise to complete raw material or work in
                process into finished goods or other finished products for
                disposition, (ii) if not required by other law, to fail to
                obtain governmental or third party consents for the collection
                or disposition of Collateral to be collected or disposed of,
                (iii) to fail to exercise collection remedies against Account
                Debtors or other Persons obligated on Collateral or to remove
                Liens on or any adverse claims against Collateral, (iv) to
                exercise collection remedies against Account Debtors and other
                Persons obligated on Collateral directly or through the use of
                collection agencies and other collection specialists, (v) to
                advertise dispositions of Collateral through publications or
                media of general circulation, whether or not the Collateral is
                of a specialized nature, (vi) to contact other Persons, whether
                or not in the same business as any Grantor, for expressions of
                interest in acquiring all or any portion of such Collateral,
                (vii) to hire one or more professional auctioneers to assist in
                the disposition of Collateral, whether or not the Collateral is
                of a specialized nature, (viii) to dispose of Collateral by
                utilizing internet sites that provide for the auction of assets
                of the types included in the Collateral or that have the
                reasonable capacity of doing so, or that match buyers and
                sellers of assets, (ix) to dispose of assets in wholesale rather
                than retail markets, (x) to disclaim disposition warranties,
                such as title, possession or quiet enjoyment, (xi) to purchase
                insurance or credit enhancements to insure Agent against risks
                of loss, collection or disposition of Collateral or to provide
                to Agent a guaranteed return from the collection or disposition
                of Collateral, or (xii) to the extent deemed appropriate by
                Agent, to obtain the services of other brokers, investment
                bankers, consultants and other professionals to assist Agent in
                the collection or disposition of any of the Collateral. Each
                Grantor acknowledges that the purpose of this Section 8(c) is to
                provide non-exhaustive indications of what actions or omissions
                by Agent would be commercially reasonable in Agent's exercise of
                remedies against the Collateral and that other actions or
                omissions by Agent shall not be deemed commercially unreasonable
                solely on account of not being indicated in this Section 8(c).
                Without limitation upon the foregoing, nothing contained in this
                Section 8(c) shall be construed to grant any rights to any
                Grantor or to impose any duties on Agent that would

                                      -16-
<PAGE>

                not have been granted or imposed by this Agreement or by
                applicable law in the absence of this Section 8(c).

            (d) Neither Agent nor any Lender shall be required to make any
                demand upon, or pursue or exhaust any of their rights or
                remedies against, any Grantor, any other obligor, guarantor,
                pledgor or any other Person with respect to the payment of the
                Obligations or to pursue or exhaust any of their rights or
                remedies with respect to any Collateral therefor or any direct
                or indirect guarantee thereof. Neither Agent nor any Lender
                shall be required to marshal the Collateral or any guarantee of
                the Obligations or to resort to the Collateral or any such
                guarantee in any particular order, and all of its and their
                rights hereunder or under any other Loan Document shall be
                cumulative. To the extent it may lawfully do so, each Grantor
                absolutely and irrevocably waives and relinquishes the benefit
                and advantage of, and covenants not to assert against Agent or
                any Lender, any valuation, stay, appraisement, extension,
                redemption or similar laws and any and all rights or defenses it
                may have as a surety now or hereafter existing which, but for
                this provision, might be applicable to the sale of any
                Collateral made under the judgment, order or decree of any
                court, or privately under the power of sale conferred by this
                Agreement, or otherwise.

9.          GRANT OF LICENSE TO USE INTELLECTUAL PROPERTY COLLATERAL

            For the purpose of enabling Agent to exercise rights and remedies
            under Section 8 hereof (including, without limiting the terms of
            Section 8 hereof, in order to take possession of, hold, preserve,
            process, assemble, prepare for sale, market for sale, sell or
            otherwise dispose of Collateral) at such time as Agent shall be
            lawfully entitled to exercise such rights and remedies, each Grantor
            hereby grants to Agent, for the benefit of Agent and Lenders, an
            irrevocable, nonexclusive license (exercisable without payment of
            royalty or other compensation to such Grantor) to use, license or
            sublicense any Intellectual Property now owned or hereafter acquired
            by such Grantor, and wherever the same may be located, and including
            in such license access to all media in which any of the licensed
            items may be recorded or stored and to all computer software and
            programs used for the compilation or printout thereof and an
            irrevocable license (exercisable without payment of rent or other
            compensation to such Grantor) to use and occupy all real estate
            owned or leased by such Grantor; provided, however, that if and to
            the extent that the grant of license to Agent would result in a
            violation of any agreements relating to the Intellectual Property or
            the real estate or cause any such agreement to be void or voidable,
            the license granted hereunder shall be deemed limited to only such
            license or rights as Grantors may be authorized to give without
            consent under such agreements without breaching or voiding such
            agreements.

10.         LIMITATION ON AGENT'S AND LENDERS' DUTY IN RESPECT OF COLLATERAL

            Agent and each Lender shall use reasonable care with respect to the
            Collateral in its possession or under its control. Neither Agent nor
            any Lender shall have any other duty as to any Collateral in its
            possession or control or in the possession or control of any agent
            or nominee of Agent or such Lender, or any income thereon or as to
            the preservation of rights against prior parties or any other rights
            pertaining thereto. Agent shall not be liable or responsible for any
            loss or damage to any of the Collateral, or for any diminution in
            the value thereof, by reason of the act or omission of any
            warehousemen, carrier, forwarding agency, consignee or other agent
            or bailee selected by Agent in good faith.

11.         REINSTATEMENT

            This Agreement shall remain in full force and effect and continue to
            be effective should any petition be filed by or against any Grantor
            for liquidation or reorganization, should any Grantor become
            insolvent or make an assignment for the benefit of any creditor or
            creditors or should a receiver or trustee be appointed for all or
            any significant part of any Grantor's assets, and shall continue to
            be effective or be reinstated, as the case may be, if at any time
            payment and performance of the Obligations, or any part thereof, is,
            pursuant to applicable law, rescinded or reduced in amount, or must
            otherwise be restored or returned by any obligee of the Obligations,
            whether as a "voidable preference," "fraudulent conveyance," or
            otherwise, all as though such payment or performance had not been
            made. In the event that any payment, or any part thereof, is
            rescinded, reduced, restored or returned, the Obligations shall be
            reinstated and deemed reduced only by such amount paid and not so
            rescinded, reduced, restored or returned.

12.         SURETYSHIP WAIVERS BY GRANTOR; OBLIGATIONS ABSOLUTE

            (a) Except as expressly provided herein, each Grantor waives demand,
                notice, protest, notice of acceptance of this Agreement, notice
                of loans made, credit extended, collateral received or delivered
                or other action taken in reliance hereon and all other demands
                and notices of any description thereof, all in such manner and
                at such time or times as Agent may deem advisable. Agent shall
                have no duty as to the collection or protection of the
                Collateral or any income thereon, nor as to the preservation of
                rights against prior parties, nor as to the preservation of any
                rights pertaining thereto beyond the safe custody thereof.

            (b) All rights of Agent hereunder, the Security Interests and all
                obligations of each Grantor hereunder shall be absolute and
                unconditional irrespective of (a) any lack of validity or
                enforceability of the Credit Agreement, any other Loan Document,
                any agreement with respect to any of the Obligations or any
                other agreement or instrument relating to any of the foregoing,
                (b) any change in the time, manner or place of payment of, or in
                any other term of, all or any of the Obligations, or any other
                amendment or waiver of or any consent to any departure from the
                Credit Agreement, any other Loan Document, or any other
                agreement or instrument, (c) any exchange, release or
                non-perfection of any Lien on other collateral, or any release
                or amendment or waiver of or consent under or departure from or
                any acceptance of partial payment thereon and or settlement,
                compromise or adjustment of any Obligation or of any guarantee,
                securing or guaranteeing all or any of the Obligations, or (d)
                any other circumstance that might otherwise constitute a defense
                available to, or a discharge of, such Grantor in respect of the
                Obligations or this Agreement.

13.         EXPENSES AND ATTORNEY'S FEES

            Without limiting any Grantor's obligations under the Credit
            Agreement or the other Loan Documents, Grantors agree, jointly and
            severally, to promptly pay all fees, costs and expenses (including
            reasonable attorneys' fees and expenses and allocated costs of
            internal legal staff) incurred in connection with (a) protecting,
            storing, warehousing, appraising, insuring, handling, maintaining
            and shipping the Collateral, (b) creating, perfecting, maintaining
            and enforcing Agent's Liens and (c) collecting, enforcing, retaking,
            holding, preparing for disposition, processing and disposing of
            Collateral.

15.         SEVERABILITY

            The invalidity, illegality, or unenforceability in any jurisdiction

                                      -19-

16.         NO WAIVER; CUMULATIVE REMEDIES

            Neither Agent nor any Lender shall by any act, delay, omission or
            otherwise be deemed to have waived any of its rights or remedies
            hereunder, and no waiver shall be valid unless in writing, signed by
            Agent and then only to the extent therein set forth. A waiver by
            Agent of any right or remedy hereunder on any one occasion shall not
            be construed as a bar to any right or remedy which Agent would
            otherwise have had on any future occasion. No failure to exercise
            nor any delay in exercising on the part of Agent or any Lender, any
            right, power or privilege hereunder, shall operate as a waiver
            thereof, nor shall any single or partial exercise of any right,
            power or privilege hereunder preclude any other or future exercise
            thereof or the exercise of any other right, power or privilege. The
            rights and remedies hereunder provided are cumulative and may be
            exercised singly or concurrently, and are not exclusive of any
            rights and remedies provided by law. None of the terms or provisions
            of this Agreement may be waived, altered, modified or amended except
            by an instrument in writing, duly executed by Agent and each
            Grantor.

17.         LIMITATION BY LAW

            All rights, remedies and powers provided in this Agreement may be
            exercised only to the extent that the exercise thereof does not
            violate any applicable provision of law, and all the provisions of
            this Agreement are intended to be subject to all applicable
            mandatory provisions of law that may be controlling and to be
            limited to the extent necessary so that they shall not render this
            Agreement invalid, unenforceable, in whole or in part, or not
            entitled to be recorded, registered or filed under the provisions of
            any applicable law.

18.         TERMINATION OF THIS AGREEMENT

            Subject to Section 11 hereof, this Agreement shall terminate upon
            the Termination Date. Following the termination of this agreement,
            Agent shall, upon reasonable request, and at the sole cost and
            expense of Grantors, execute such termination statements and other
            releases (in form and substance reasonably satisfactory to Agent)
            with respect to security granted hereunder, and Agent shall at such
            time transfer any Instrument or Chattel Paper or other item of
            Collateral delivered to the Agent hereunder to the Grantors, without
            recourse and without representation of warranty.

19.         SUCCESSORS AND ASSIGNS

            This Agreement and all obligations of each Grantor hereunder shall
            be binding upon the successors and permitted assigns of such Grantor
            (including any debtor-in-possession on behalf of such Grantor) and
            shall, together with the rights and remedies of Agent, for the
            benefit of Agent and Lenders, hereunder, inure to the benefit of
            Agent and Lenders, all future holders of any instrument evidencing
            any of the Obligations and their respective successors and permitted
            assigns except that Grantors may not assign any of their rights or
            obligations hereunder without the written consent of all Lenders
            which assignment without such consent shall be void. No sales of
            participations, other sales, assignments, transfers or other
            dispositions of any agreement governing or instrument evidencing the
            Obligations or any portion thereof or interest therein shall in any
            manner impair the Lien granted to Agent, for the benefit of Agent
            and Lenders, hereunder.

20.         COUNTERPARTS

            This Agreement and any amendments, waivers, consents or supplements
            may be executed in any number of counterparts and by different
            parties hereto in separate counterparts, each of which when so
            executed and delivered shall be deemed an original, but all of which
            counterparts

                                      -20-
<PAGE>

            together shall constitute but one in the same instrument. This
            Agreement shall become effective upon the execution of a counterpart
            hereof by each of the parties hereto.

21.         GOVERNING LAW

            (a) THIS SECURITY AGREEMENT AND THE OBLIGATIONS ARISING HEREUNDER
                SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN
                ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK
                WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES WHICH SHALL BE
                DEEMED NOT TO INCLUDE SECTION 5-1401 OF THE NEW YORK GENERAL
                OBLIGATIONS LAW.

            (b) EACH GRANTOR HEREBY CONSENTS TO THE JURISDICTION OF ANY STATE OR
                FEDERAL COURT LOCATED WITHIN NEW YORK COUNTY, STATE OF NEW YORK
                AND IRREVOCABLY AGREES THAT, SUBJECT TO AGENT'S ELECTION, ALL
                ACTIONS OR PROCEEDINGS ARISING OUT OF OR RELATING TO THIS
                AGREEMENT OR THE OTHER LOAN DOCUMENTS SHALL BE LITIGATED IN SUCH
                COURTS. EACH GRANTOR EXPRESSLY SUBMITS AND CONSENTS TO THE
                JURISDICTION OF THE AFORESAID COURTS AND WAIVES ANY DEFENSE OF
                FORUM NON CONVENIENS. EACH GRANTOR HEREBY WAIVES PERSONAL
                SERVICE OF ANY AND ALL PROCESS AND AGREES THAT ALL SUCH SERVICE
                OF PROCESS MAY BE MADE UPON SUCH GRANTOR BY CERTIFIED OR
                REGISTERED MAIL, RETURN RECEIPT REQUESTED, ADDRESSED TO SUCH
                GRANTOR, AT THE ADDRESS SET FORTH IN THIS AGREEMENT AND SERVICE
                SO MADE SHALL BE COMPLETE TEN (10) DAYS AFTER THE SAME HAS BEEN
                POSTED. IN ANY LITIGATION, TRIAL, ARBITRATION OR OTHER DISPUTE
                RESOLUTION PROCEEDING RELATING TO THIS AGREEMENT OR ANY OF THE
                OTHER LOAN DOCUMENTS, ALL DIRECTORS, OFFICERS, EMPLOYEES AND
                AGENTS OF GRANTORS, CREDIT PARTIES OR ANY OF THEIR AFFILIATES
                SHALL BE DEEMED TO BE EMPLOYEES OR MANAGING AGENTS OF GRANTORS
                OR SUCH CREDIT PARTIES FOR PURPOSES OF ALL APPLICABLE LAW OR
                COURT RULES REGARDING THE PRODUCTION OF WITNESSES BY NOTICE FOR
                TESTIMONY (WHETHER IN A DEPOSITION, AT TRIAL OR OTHERWISE).
                GRANTORS AND CREDIT PARTIES AGREE THAT AGENT'S OR ANY LENDER'S
                COUNSEL IN ANY SUCH DISPUTE RESOLUTION PROCEEDING MAY EXAMINE
                ANY OF THESE INDIVIDUALS AS IF UNDER CROSS-EXAMINATION AND THAT
                ANY DISCOVERY DEPOSITION OF ANY OF THEM MAY BE USED IN THAT
                PROCEEDING AS IF IT WERE AN EVIDENCE DEPOSITION. GRANTORS AND
                CREDIT PARTIES IN ANY EVENT WILL USE ALL COMMERCIALLY REASONABLE
                EFFORTS TO PRODUCE IN ANY SUCH DISPUTE RESOLUTION PROCEEDING, AT
                THE TIME AND IN THE MANNER REQUESTED BY AGENT OR ANY LENDER, ALL
                PERSONS, DOCUMENTS (WHETHER IN TANGIBLE, ELECTRONIC OR OTHER
                FORM) OR OTHER THINGS UNDER THEIR CONTROL AND RELATING TO THE
                DISPUTE.

22.         WAIVER OF JURY TRIAL

            EACH GRANTOR HEREBY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM
            OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS SECURITY
            AGREEMENT AND THE OTHER LOAN DOCUMENTS. EACH GRANTOR

                                      -21-
<PAGE>

            ACKNOWLEDGES THAT THIS WAIVER IS A MATERIAL INDUCEMENT TO ENTER INTO

            AND WILL CONTINUE TO RELY ON THE WAIVER IN THEIR RELATED FUTURE
            DEALINGS. EACH GRANTOR WARRANTS AND REPRESENTS THAT SUCH GRANTOR HAS

            COUNSEL, AND THAT SUCH GRANTOR KNOWINGLY AND VOLUNTARILY WAIVES ITS
            JURY TRIAL RIGHTS.

23.         HEADINGS

            Section and subsection headings are included herein for convenience
            of reference only and shall not constitute a part of this Agreement
