Commitment. Within the foregoing limits and subject to the terms and conditions
set forth herein, the Borrower may borrow, prepay and reborrow Revolving Loans.

         (b)   Term Commitment. Subject to the terms and conditions set forth
herein, on the Effective Date, each Term Lender agrees to make one Term Loan to
the Borrower equal to such Term Lender's Term Commitment. No amounts paid or
prepaid with respect to the Term Loans may be reborrowed. Upon a Term Lender
making such Term Loan, its Term Commitment shall terminate and it shall have no
further Commitment to make Term Loans.

     SECTION 2.02 Loans and Borrowings.

         (a)   Each Loan shall be made as part of a Borrowing consisting of
Loans made by the Lenders ratably in accordance with their respective
Commitments. Each Competitive Loan shall be made in accordance with the
procedures set forth in Section 2.04. The failure of any Lender to make any Loan
required to be made by it shall not relieve any other Lender of its obligations
hereunder; provided that the Commitments and Competitive Bids of the Lenders are
several and no Lender shall be responsible for any other Lender's failure to
make Loans as required.

         (b)   Subject to Section 2.14, (i) each Borrowing shall be comprised
entirely of ABR Loans or Eurodollar Loans as the Borrower may request in
accordance herewith, and (ii) each Competitive Borrowing shall be comprised
entirely of Eurodollar Loans or Fixed Rate Loans as the Borrower may request in
accordance herewith. Each Lender at its option may make

                                                                              24

<PAGE>

any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of
such Lender to make such Loan; provided that any exercise of such option shall
not affect the obligation of the Borrower to repay such Loan in accordance with
the terms of this Agreement.

         (c)   At the commencement of each Interest Period for any Eurodollar
Borrowing, such Borrowing shall be in an aggregate amount that is an integral
multiple of $2,000,000 and not less than $10,000,000. At the time that each ABR
Borrowing is made, such Borrowing shall be in an aggregate amount that is an
integral multiple of $2,000,000 and not less than $10,000,000; provided that an
ABR Borrowing may be in an aggregate amount that is equal to the entire unused
balance of the Aggregate Revolving Commitment or that is required to finance the
reimbursement of an LC Disbursement as contemplated by Section 2.05(e). Subject
to Section 2.04(d), each Competitive Borrowing shall be in an aggregate amount
that is an integral multiple of $2,000,000 and not less than $10,000,000.
Borrowings of more than one Type and Class may be outstanding at the same time;
provided that there shall not at any time be more than a total of five
Eurodollar Borrowings outstanding.

         (d)   The Borrower shall not be entitled to request any Borrowing after
the Revolving Commitment Termination Date, or to elect to convert or continue
any Borrowing if the Interest Period requested with respect thereto would end
after the Revolving Commitment Termination Date or Term Maturity Date (as
applicable).

     SECTION 2.03 Requests for Borrowings. To request a Borrowing, the Borrower
shall notify the Administrative Agent of such request by telephone (a) in the
case of a Eurodollar Borrowing, not later than 11:00 a.m., Dallas, Texas time,
three Business Days before the date of the proposed Borrowing or (b) in the case
of an ABR Borrowing, not later than 10:00 a.m., Dallas, Texas time, on the date
of the proposed Borrowing. Each such telephonic Borrowing Request shall be
irrevocable and shall be confirmed promptly by hand delivery or telecopy to the
Administrative Agent of a written Borrowing Request executed by an Authorized
Officer of the Borrower. Each such telephonic and written Borrowing Request
shall specify the following information in compliance with Section 2.02:

         (i)   the aggregate amount of the requested Borrowing;

         (ii)  the date of such Borrowing, which shall be a Business Day;

         (iii) whether such Borrowing is to be an ABR Borrowing or a Eurodollar
     Borrowing;

         (iv)  in the case of a Eurodollar Borrowing, the initial Interest
     Period to be applicable thereto, which shall be a period contemplated by
     the definition of the term "Interest Period"; and

         (v)   the location and number of the Borrower's account to which funds
     are to be disbursed, which shall comply with the requirements of Section
     2.06.

If no election as to the Type of Borrowing is specified, then the requested
Borrowing shall be an ABR Borrowing. If no Interest Period is specified with
respect to any requested Eurodollar

                                                                              25

<PAGE>

Borrowing, then the Borrower shall be deemed to have selected an Interest Period
of one month's duration. Promptly following receipt of a Borrowing Request in
accordance with this Section 2.03, the Administrative Agent shall advise each
Revolving Lender of the details thereof and of the amount of such Revolving
Lender's Revolving Loan to be made as part of the requested Borrowing.

     SECTION 2.04 Competitive Bid Procedure.

         (a)   Subject to the terms and conditions set forth herein, from time
to time during the Availability Period the Borrower may request Competitive Bids
and may (but shall not have any obligation to) accept Competitive Bids and
borrow Competitive Loans; provided that (1) the aggregate principal amount of
outstanding Competitive Loans at any time shall not exceed $50,000,000, and (2)
the sum of the Aggregate Revolving Credit Exposures plus the aggregate principal
amount of outstanding Competitive Loans at any time shall not exceed the
Aggregate Revolving Commitment. To request Competitive Bids, the Borrower shall
notify the Administrative Agent of such request by telephone, in the case of a
Eurodollar Borrowing, not later than 11:00 a.m., Dallas, Texas time, four
Business Days before the date of the proposed Borrowing and, in the case of a
Fixed Rate Borrowing, not later than 10:00 a.m., Dallas, Texas time, one
Business Day before the date of the proposed Borrowing; provided that the
Borrower may submit up to (but not more than) two (2) Competitive Bid Requests
on the same day, but a Competitive Bid Request shall not be made within five
Business Days after the date of any previous Competitive Bid Request, unless any
and all such previous Competitive Bid Requests shall have been withdrawn or all
Competitive Bids received in response thereto rejected. Each such telephonic
Competitive Bid Request shall be confirmed promptly by hand delivery or telecopy
to the Administrative Agent of a written Competitive Bid Request in a form
approved by the Administrative Agent and executed by an Authorized Officer of
the Borrower. Each such telephonic and written Competitive Bid Request shall
specify the following information in compliance with Section 2.02:

         (i)   the aggregate amount of the requested Borrowing;

         (ii)  the date of such Borrowing, which shall be a Business Day;

         (iii) whether such Borrowing is to be a Eurodollar Borrowing or a
     Fixed Rate Borrowing;

         (iv)  the Interest Period to be applicable to such Borrowing, which
     shall be a period contemplated by the definition of the term "Interest
     Period"; and

         (v)   the location and number of the Borrower's account to which funds
     are to be disbursed, which shall comply with the requirements of Section
     2.06.

Promptly following receipt of a Competitive Bid Request in accordance with this
Section 2.04, the Administrative Agent shall notify the Revolving Lenders of the
details thereof by telecopy, inviting the Revolving Lenders to submit
Competitive Bids.

                                                                              26

<PAGE>

         (b)   Each Revolving Lender may (but shall not have any obligation to)
make one or more Competitive Bids to the Borrower in response to a Competitive
Bid Request. Each Competitive Bid by a Revolving Lender must be in a form
approved by the Administrative Agent and must be received by the Administrative
Agent by telecopy, in the case of a Eurodollar Competitive Borrowing, not later
than 9:30 a.m., Dallas, Texas time, three Business Days before the proposed date
of such Competitive Borrowing, and in the case of a Fixed Rate Borrowing, not
later than 9:30 a.m., Dallas, Texas time, on the proposed date of such
Competitive Borrowing. Competitive Bids that do not conform substantially to the
form approved by the Administrative Agent may be rejected by the Administrative
Agent, and the Administrative Agent shall notify the applicable Revolving Lender
as promptly as practicable. Each Competitive Bid shall specify (i) the principal
amount (which shall be a minimum of $10,000,000 and an integral multiple of
$2,000,000 and which may equal the entire principal amount of the Competitive
Borrowing requested by the Borrower) of the Competitive Loan or Competitive
Loans that the Revolving Lender is willing to make, (ii) the Competitive Bid
Rate or Competitive Bid Rates at which the Revolving Lender is prepared to make
such Competitive Loan or Competitive Loans (expressed as a percentage rate per
annum in the form of a decimal to no more than four decimal places) and (iii)
the Interest Period applicable to each such Competitive Loan and the last day
thereof.

         (c)   The Administrative Agent shall promptly notify the Borrower by
telecopy of the Competitive Bid Rate and the principal amount specified in each
Competitive Bid and the identity of the Revolving Lender that shall have made
such Competitive Bid.

         (d)   Subject only to the provisions of this Section 2.04(d), the
Borrower may accept or reject any Competitive Bid. The Borrower shall notify the
Administrative Agent by telephone, confirmed by telecopy in a form approved by
the Administrative Agent, whether and to what extent it has decided to accept or
reject each Competitive Bid, in the case of a Eurodollar Competitive Borrowing,
not later than 10:30 a.m., Dallas, Texas time, three Business Days before the
date of the proposed Competitive Borrowing, and in the case of a Fixed Rate
Borrowing, not later than 10:30 a.m., Dallas, Texas time, on the proposed date
of the Competitive Borrowing; provided that (i) the failure of the Borrower to
give such notice shall be deemed to be a rejection of each Competitive Bid, (ii)
the Borrower shall not accept a Competitive Bid made at a particular Competitive
Bid Rate if the Borrower rejects a Competitive Bid made at a lower Competitive
Bid Rate, (iii) the aggregate amount of the Competitive Bids accepted by the
Borrower shall not exceed the aggregate amount of the requested Competitive
Borrowing specified in the related Competitive Bid Request, (iv) to the extent
necessary to comply with clause (iii) above, the Borrower may accept Competitive
Bids at the same Competitive Bid Rate in part, which acceptance, in the case of
multiple Competitive Bids at such Competitive Bid Rate, shall be made pro rata
in accordance with the amount of each such Competitive Bid, and (v) except
pursuant to clause (iv) above, no Competitive Bid shall be accepted for a
Competitive Loan unless such Competitive Loan is in a minimum principal amount
of $10,000,000 and an integral multiple of $2,000,000; provided further that if
a Competitive Loan must be in an amount less than $10,000,000 because of the
provisions of clause (iv) above, such Competitive Loan may be for a minimum of
$2,000,000 or any integral multiple thereof, and in calculating the pro rata
allocation of acceptances of portions of multiple Competitive Bids at a
particular Competitive Bid Rate pursuant to clause (iv), the amounts shall

                                                                              27

<PAGE>

be rounded to integral multiples of $2,000,000 in a manner determined by the
Borrower. A notice given by the Borrower pursuant to this Section 2.04(d) shall
be irrevocable.

         (e)   The Administrative Agent shall promptly notify each bidding
Revolving Lender by telecopy whether or not its Competitive Bid has been
accepted (and, if so, the amount and Competitive Bid Rate so accepted), and each
successful bidder will thereupon become bound, subject to the terms and
conditions hereof, to make the Competitive Loan in respect of which its
Competitive Bid has been accepted.

         (f)   If the Administrative Agent shall elect to submit a Competitive
Bid in its capacity as a Revolving Lender, it shall submit such Competitive Bid
directly to the Borrower at least one quarter of an hour earlier than the time
by which the other Revolving Lenders are required to submit their Competitive
Bids to the Administrative Agent pursuant to paragraph (b) of this Section 2.04.

         (g)   Any Revolving Lender which makes a Competitive Loan hereunder may
request that such Competitive Loan be evidenced by a promissory note. In such
event, the Borrower shall prepare, execute and deliver to such Revolving Lender
a promissory note payable to the order of such Revolving Lender and in a form
approved by the Administrative Agent.

     SECTION 2.05 Letters of Credit.

         (a)   General. Subject to the terms and conditions set forth herein,
the Borrower may request the issuance of Letters of Credit for its own account,
in a form reasonably acceptable to the Administrative Agent and the Issuing
Bank, at any time and from time to time during the Availability Period. In the
event of any inconsistency between the terms and conditions of this Agreement
and the terms and conditions of any form of letter of credit application or
other agreement submitted by the Borrower to, or entered into by the Borrower
with, the Issuing Bank relating to any Letter of Credit, the terms and
conditions of this Agreement shall control.

         (b)   Notice of Issuance, Amendment, Renewal, Extension; Certain
Conditions. To request the issuance of a Letter of Credit (or the amendment,
renewal or extension of an outstanding Letter of Credit), the Borrower shall
hand deliver or telecopy (or transmit by electronic communication, if
arrangements for doing so have been approved by the Issuing Bank) to the Issuing
Bank and the Administrative Agent (reasonably in advance of the requested date
of issuance, amendment, renewal or extension) a notice requesting the issuance
of a Letter of Credit, or identifying the Letter of Credit to be amended,
renewed or extended, and specifying the date of issuance, amendment, renewal or
extension (which shall be a Business Day), the date on which such Letter of
Credit is to expire (which shall comply with paragraph (c) of this Section
2.05), the amount of such Letter of Credit, the name and address of the
beneficiary thereof and such other information as shall be necessary to prepare,
amend, renew or extend such Letter of Credit. If requested by the Issuing Bank,
the Borrower also shall submit a letter of credit application on the Issuing
Bank's standard form in connection with any request for a Letter of Credit. A
Letter of Credit shall be issued, amended, renewed or extended only if (and upon
issuance, amendment, renewal or extension of each Letter of Credit the Borrower
shall be

                                                                              28

<PAGE>

deemed to represent and warrant that), after giving effect to such issuance,
amendment, renewal or extension (i) the LC Exposure shall not exceed
$100,000,000, (ii) the sum of the Aggregate Revolving Credit Exposure plus the
aggregate principal amount of outstanding Competitive Loans shall not exceed the
Aggregate Revolving Commitment and (iii) no Default shall have occurred and be
continuing.

         (c)   Expiration Date. Each Letter of Credit shall expire at or prior
to the close of business on the earlier of (i) the date one year after the date
of the issuance of such Letter of Credit (or, in the case of any renewal or
extension thereof, one year after such renewal or extension) and (ii) the date
that is five Business Days prior to the Revolving Commitment Termination Date.

         (d)   Participations. By the issuance of a Letter of Credit (or an
amendment to a Letter of Credit increasing the amount thereof) and without any
further action on the part of the Issuing Bank or the Revolving Lenders, the
Issuing Bank hereby grants to each Revolving Lender, and each Revolving Lender
hereby acquires from the Issuing Bank, a participation in such Letter of Credit
equal to such Revolving Lender's Revolving Credit Percentage of the aggregate
amount available to be drawn under such Letter of Credit. In consideration and
in furtherance of the foregoing, each Revolving Lender hereby absolutely and
unconditionally agrees to pay to the Administrative Agent, for the account of
the Issuing Bank, such Revolving Lender's Revolving Credit Percentage of each LC
Disbursement made by the Issuing Bank and not reimbursed by the Borrower on the
date due as provided in paragraph (e) of this Section 2.05, or of any
reimbursement payment required to be refunded to the Borrower for any reason.
Each Revolving Lender acknowledges and agrees that its obligation to acquire
participations pursuant to this Section 2.05(d) in respect of Letters of Credit
is absolute and unconditional and shall not be affected by any circumstance
whatsoever, including any amendment, renewal or extension of any Letter of
Credit or the occurrence and continuance of a Default or reduction or
termination of the Commitments, and that each such payment shall be made without
any offset, abatement, withholding or reduction whatsoever.

         (e)   Reimbursement. If the Issuing Bank shall make any LC Disbursement
in respect of a Letter of Credit, the Borrower shall reimburse such LC
Disbursement by paying to the Administrative Agent an amount equal to such LC
Disbursement not later than 12:00 noon, Dallas, Texas time, on the date that
such LC Disbursement is made, if the Borrower shall have received notice of such
LC Disbursement prior to 10:00 a.m., Dallas, Texas time, on such date, or, if
such notice has not been received by the Borrower prior to such time on such
date, then not later than 12:00 noon, Dallas, Texas time, on (i) the Business
Day that the Borrower receives such notice, if such notice is received prior to
10:00 a.m., Dallas, Texas time, on the day of receipt, or (ii) the Business Day
immediately following the day that the Borrower receives such notice, if such
notice is not received prior to such time on the day of receipt; provided that,
the Borrower may, subject to the conditions to Borrowing set forth herein,
request in accordance with Section 2.03 that such payment be financed with an
ABR Borrowing in an equivalent amount and, to the extent so financed, the
Borrower's obligation to make such payment shall be discharged and replaced by
the resulting ABR Borrowing. If the Borrower fails to make such payment when
due, the Administrative Agent shall notify each Revolving Lender of the
applicable LC Disbursement, the payment then due from the Borrower in respect
thereof and

                                                                              29

<PAGE>

such Revolving Lender's Revolving Credit Percentage thereof. Promptly following
receipt of such notice, each Revolving Lender shall pay to the Administrative
Agent its Revolving Credit Percentage of the unreimbursed LC Disbursement, in
the same manner as provided in Section 2.06 with respect to Revolving Loans made
by such Revolving Lender (and Section 2.06 shall apply, mutatis mutandis, to the
payment obligations of the Revolving Lenders), and the Administrative Agent
shall promptly pay to the Issuing Bank the amounts so received by it from the
Lenders. Promptly following receipt by the Administrative Agent of any payment
from the Borrower pursuant to this Section 2.05(e), the Administrative Agent
shall distribute such payment to the Issuing Bank or, to the extent that
Revolving Lenders have made payments pursuant to this Section 2.05(e) to
reimburse the Issuing Bank, then to such Revolving Lenders and the Issuing Bank
as their interests may appear. Any payment made by a Revolving Lender pursuant
to this Section 2.05(e) to reimburse the Issuing Bank for any LC Disbursement
(other than the funding of ABR Loans as contemplated above) shall not constitute
a Revolving Loan and shall not relieve the Borrower of its obligation to
reimburse such LC Disbursement.

         (f)   Obligations Absolute. The Borrower's obligation to reimburse LC
Disbursements as provided in paragraph (e) of this Section 2.05 shall be
absolute, unconditional and irrevocable, and shall be performed strictly in
accordance with the terms of this Agreement under any and all circumstances
whatsoever and irrespective of (i) any lack of validity or enforceability of any
Letter of Credit or this Agreement, or any term or provision therein, (ii) any
draft or other document presented under a Letter of Credit proving to be forged,
fraudulent or invalid in any respect or any statement therein being untrue or
inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of
Credit against presentation of a draft or other document that does not comply
with the terms of such Letter of Credit, or (iv) any other event or circumstance
whatsoever, whether or not similar to any of the foregoing, that might, but for
the provisions of this Section 2.05(f), constitute a legal or equitable
discharge of, or provide a right of setoff against, the Borrower's obligations
hereunder. Neither the Agents, the Lenders nor the Issuing Bank, nor any of
their Related Parties, shall have any liability or responsibility by reason of
or in connection with the issuance or transfer of any Letter of Credit or any
payment or failure to make any payment thereunder (irrespective of any of the
circumstances referred to in the preceding sentence), or any error, omission,
interruption, loss or delay in transmission or delivery of any draft, notice or
other communication under or relating to any Letter of Credit (including any
document required to make a drawing thereunder), any error in interpretation of
technical terms or any consequence arising from causes beyond the control of the
Issuing Bank; provided that the foregoing shall not be construed to excuse the
Issuing Bank from liability to the Borrower to the extent of any direct damages
(as opposed to consequential damages, claims in respect of which are hereby
waived by the Borrower to the extent permitted by applicable law) suffered by
the Borrower that are caused by the Issuing Bank's failure to exercise care when
determining whether drafts and other documents presented under a Letter of
Credit comply with the terms thereof. The parties hereto expressly agree that,
in the absence of gross negligence or willful misconduct on the part of the
Issuing Bank (as finally determined by a court of competent jurisdiction), the
Issuing Bank shall be deemed to have exercised care in each such determination.
In furtherance of the foregoing and without limiting the generality thereof, the
parties agree that, with respect to documents presented which appear on their
face to be in substantial compliance with the terms of a Letter of Credit, the
Issuing Bank may, in its sole

                                                                              30

<PAGE>

discretion, either accept and make payment upon such documents without
responsibility for further investigation, regardless of any notice or
information to the contrary, or refuse to accept and make payment upon such
documents if such documents are not in strict compliance with the terms of such
Letter of Credit.

         (g)   Disbursement Procedures. The Issuing Bank shall, promptly
following its receipt thereof, examine all documents purporting to represent a
demand for payment under a Letter of Credit. The Issuing Bank shall promptly
notify the Administrative Agent and the Borrower by telephone (confirmed by
telecopy) of such demand for payment and whether the Issuing Bank has made or
will make an LC Disbursement thereunder; provided that any failure to give or
delay in giving such notice shall not relieve the Borrower of its obligation to
reimburse the Issuing Bank and the Revolving Lenders with respect to any such LC
Disbursement.

         (h)   Interim Interest. If the Issuing Bank shall make any LC
Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in
full on the date such LC Disbursement is made, the unpaid amount thereof shall
bear interest, for each day from and including the date such LC Disbursement is
made to but excluding the date that the Borrower reimburses such LC
Disbursement, at the rate per annum then applicable to ABR Loans; provided that,
if the Borrower fails to reimburse such LC Disbursement when due pursuant to
paragraph (e) of this Section 2.05, then Section 2.13(d) shall apply. Interest
accrued pursuant to this Section 2.05(h) shall be for the account of the Issuing
Bank, except that interest accrued on and after the date of payment by any
Revolving Lender pursuant to paragraph (e) of this Section 2.05 to reimburse the
Issuing Bank shall be for the account of such Revolving Lender to the extent of
such payment.

         (i)   Replacement of the Issuing Bank. The Issuing Bank may be replaced
at any time by written agreement among the Borrower, the Administrative Agent,
the replaced Issuing Bank and the successor Issuing Bank. The Administrative
Agent shall notify the Revolving Lenders of any such replacement of the Issuing
Bank. At the time any such replacement shall become effective, the Borrower
shall pay all unpaid fees accrued for the account of the replaced Issuing Bank
pursuant to Section 2.12(b). From and after the effective date of any such
replacement, (i) the successor Issuing Bank shall have all the rights and
obligations of the Issuing Bank under this Agreement with respect to Letters of
Credit to be issued thereafter and (ii) references herein to the term "Issuing
Bank" shall be deemed to refer to such successor or to any previous Issuing
Bank, or to such successor and all previous Issuing Banks, as the context shall
require. After the replacement of an Issuing Bank hereunder, the replaced
Issuing Bank shall remain a party hereto and shall continue to have all the
rights and obligations of an Issuing Bank under this Agreement with respect to
Letters of Credit issued by it prior to such replacement, but shall not be
required to issue additional Letters of Credit.

         (j)   Cash Collateralization. If (i) any Event of Default shall occur
and be continuing, on the Business Day that the Borrower receives notice from
the Administrative Agent or the Required Revolving Lenders (or, if the maturity
of the Revolving Loans has been accelerated, Revolving Lenders with LC Exposure
representing not less than fifty-one percent (51%) of the total LC Exposure)
demanding the deposit of cash collateral pursuant to this Section 2.05(j),
and/or otherwise (ii) on the Revolving Commitment Termination Date, the

                                                                              31

<PAGE>

Borrower shall deposit in an account with the Administrative Agent, in the name
of the Administrative Agent and for the benefit of the Revolving Lenders, an
amount in cash equal to the LC Exposure as of such date plus any accrued and
unpaid interest thereon; provided that the obligation to deposit such cash
collateral shall become effective immediately, and such deposit shall become
immediately due and payable, without demand or other notice of any kind, upon
the occurrence of any Event of Default with respect to the Borrower described in
clause (h) or (i) of Article VIII. Such deposit shall be held by the
Administrative Agent as collateral for the payment and performance of the
obligations of the Borrower under this Agreement, and the Borrower will, in
connection therewith, execute and deliver such security and pledge agreements in
form and substance satisfactory to the Administrative Agent which the
Administrative Agent may, in its discretion, require. The Administrative Agent
shall have exclusive dominion and control, including the exclusive right of
withdrawal, over such account. Other than any interest earned on the investment
of such deposits, which investments shall be made at the option and sole
discretion of the Administrative Agent and at the Borrower's risk and expense,
such deposits shall not bear interest. Interest or profits, if any, on such
investments shall accumulate in such account. Moneys in such account shall be
applied by the Administrative Agent to reimburse the Issuing Bank for LC
Disbursements for which it has not been reimbursed and, to the extent not so
applied, shall be held for the satisfaction of the reimbursement obligations of
the Borrower for the LC Exposure at such time or, if the maturity of the
Revolving Loans has been accelerated (but subject to the consent of Revolving
Lenders with LC Exposure representing not less than fifty-one percent (51%) of
the total LC Exposure), be applied to satisfy other obligations of the Borrower
under this Agreement, and the Borrower will, in connection therewith, execute
and deliver such security and pledge agreements in form and substance
satisfactory to the Administrative Agent which the Administrative Agent may, in
its discretion, require. If the Borrower is required to provide an amount of
cash collateral hereunder as a result of the occurrence of an Event of Default,
such amount (to the extent not applied as aforesaid) shall be returned to the
Borrower within three Business Days after all Events of Default have been cured
or waived.

     SECTION 2.06 Funding of Borrowings.

         (a)   Each Lender shall make each Loan to be made by it hereunder on
the proposed date thereof by wire transfer of immediately available funds by
12:00 noon, Dallas, Texas time, to the account of the Administrative Agent most
recently designated by it for such purpose by notice to the Lenders. The
Administrative Agent will make such Loans available to the Borrower by promptly
crediting the amounts so received, in like funds, to an account of the Borrower
maintained with the Administrative Agent in Dallas, Texas and designated by the
Borrower; provided that ABR Loans made to finance the reimbursement of an LC
Disbursement as provided in Section 2.05(e) shall be remitted by the
Administrative Agent to the Issuing Bank.

         (b)   Unless the Administrative Agent shall have received notice from a
Revolving Lender prior to the proposed date of any Borrowing that such Revolving
Lender will not make available to the Administrative Agent such Revolving
Lender's share of such Borrowing, the Administrative Agent may assume that such
Revolving Lender has made such share available on such date in accordance with
paragraph (a) of this Section 2.06 and may, in reliance upon such assumption,
make available to the Borrower a corresponding amount. In such

                                                                              32

<PAGE>

event, if a Revolving Lender has not in fact made its share of the applicable
Borrowing available to the Administrative Agent, then the applicable Revolving
Lender and the Borrower severally agree to pay to the Administrative Agent
forthwith on demand such corresponding amount with interest thereon, for each
day from and including the date such amount is made available to the Borrower to
but excluding the date of payment to the Administrative Agent, at (i) in the
case of such Revolving Lender, the greater of (A) the Federal Funds Effective
Rate and (B) a rate determined by the Administrative Agent in accordance with
banking industry rules on interbank compensation or (ii) in the case of the
Borrower, the interest rate applicable to ABR Loans. If such Revolving Lender
pays such amount to the Administrative Agent, then such amount shall constitute
such Revolving Lender's Revolving Loan included in such Borrowing.

     SECTION 2.07 Interest Elections.

         (a)   Each Borrowing initially shall be of the Type specified in the
applicable Borrowing Request (or an ABR Borrowing if no Type is specified) and,
in the case of a Eurodollar Borrowing, shall have an initial Interest Period as
specified in such Borrowing Request. Thereafter, the Borrower may elect to
convert such Borrowing to a different Type or to continue such Borrowing and, in
the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as
provided in this Section 2.07. The Borrower may elect different options with
respect to different portions of the affected Borrowing, in which case each such
portion shall be allocated ratably among the Lenders holding the Loans
comprising such Borrowing, and the Loans comprising each such portion shall be
considered a separate Borrowing. This Section 2.07 shall not apply to
Competitive Borrowings, which may not be converted or continued.

         (b)   To make an election pursuant to this Section 2.07, the Borrower
shall notify the Administrative Agent of such election by telephone by the time
that a Borrowing Request would be required under Section 2.03 if the Borrower
were requesting a Borrowing of the Type resulting from such election to be made
on the effective date of such election. Each such telephonic Interest Election
Request shall be irrevocable and shall be confirmed promptly by hand delivery or
telecopy to the Administrative Agent of a written Interest Election Request
executed by an Authorized Officer of the Borrower.

         (c)   Each telephonic and written Interest Election Request shall
specify the following information in compliance with Section 2.02:

         (i)   the Borrowing to which such Interest Election Request applies
     and, if different options are being elected with respect to different
     portions thereof, the portions thereof to be allocated to each resulting
     Borrowing (in which case the information to be specified pursuant to
     clauses (iii) and (iv) below shall be specified for each resulting
     Borrowing);

         (ii)  the effective date of the election made pursuant to such Interest
     Election Request, which shall be a Business Day;

         (iii) whether the resulting Borrowing is to be an ABR Borrowing or a
     Eurodollar Borrowing; and

                                                                              33

<PAGE>

         (iv)  if the resulting Borrowing is a Eurodollar Borrowing, the
     Interest Period to be applicable thereto after giving effect to such
     election, which shall be a period contemplated by the definition of the
     term "Interest Period".

If any such Interest Election Request requests a Eurodollar Borrowing but does
not specify an Interest Period, then the Borrower shall be deemed to have
selected an Interest Period of one month's duration.

         (d)   Promptly following receipt of an Interest Election Request, the
Administrative Agent shall advise each applicable Lender of the details thereof
and of such Lender's portion of each resulting Borrowing.

         (e)   If the Borrower fails to deliver a timely Interest Election
Request with respect to a Eurodollar Borrowing prior to the end of the Interest
Period applicable thereto, then, unless such Borrowing is repaid as provided
herein, at the end of such Interest Period such Borrowing shall be converted to
an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of
Default has occurred and is continuing and the Administrative Agent, at the
request of the Required Lenders, so notifies the Borrower, then, so long as an
Event of Default is continuing (i) no outstanding Borrowing may be converted to
or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar
Borrowing shall be converted to an ABR Borrowing at the end of the Interest
Period applicable thereto.

     SECTION 2.08 Notes and Amortization.

         (a)   Revolving Credit Notes. The Borrower's obligation to pay the
principal of, and interest on, the Revolving Loans made by each Revolving Lender
shall be further evidenced by the Borrower's issuance, execution and delivery of
a Revolving Credit Note payable to the order of each such Revolving Lender in
the amount of such Revolving Lender's Revolving Credit Commitment, and shall be
dated as of the date of issuance of such Revolving Credit Note. The principal
amount of each Revolving Credit Note shall be payable on or before the Revolving
Commitment Termination Date.

         (b)   Term Notes and Amortization. The Borrower's obligation to pay the
principal of, and interest on, the Term Loans maintained outstanding by each
Term Lender shall be further evidenced by the Borrower's issuance, execution and
delivery of a Term Note payable to the order of each such Term Lender in the
principal amount of such Term Lender's Term Commitment, and shall be dated as of
the date of issuance of such Term Note. The aggregate principal amount of the
Term Notes applicable to the aggregate Term Loans of all the Term Lenders shall
be payable in quarterly installments of the amounts set forth below:

                                                                              34

The first such quarterly installment shall be payable on September 30, 2002, and
the remaining quarterly installments shall be payable on each Quarterly Date
thereafter, with the final installment in the amount of the aggregate unpaid
principal balance then owing being payable on or before the Term Maturity Date.

     SECTION 2.09 Termination and Reduction of Commitments; Certain Prepayments.

         (a)   Unless previously terminated, the Revolving Commitment of each
Revolving Lender shall terminate on the Revolving Commitment Termination Date
applicable to such Revolving Lender's Revolving Commitment.

         (b)   The Term Commitment of each Term Lender shall terminate on the
Effective Date upon such Term Lender making its Term Loan.

         (c)   In the event the Borrower shall, prior to the Revolving
Commitment Termination Date, receive Net Cash Proceeds from any Asset
Disposition or any Debt Offering, an amount equal to seventy-five percent (75%)
of such Net Cash Proceeds shall be applied on such date to the prepayment of the
Term Loans and the reduction of the Revolving Commitments as set forth in
Section 2.11(e).

                                                                              35

<PAGE>

         (d)   The Borrower may at any time terminate, or from time to time
reduce, the Revolving Commitments; provided that (i) each reduction of the
Revolving Commitments shall be in an amount that is an integral multiple of
$2,000,000 and not less than $10,000,000, and (ii) the Borrower shall not
terminate or reduce the Revolving Commitments if, after giving effect to any
concurrent prepayment of the Revolving Loans in accordance with Section 2.11(c),
the sum of the Aggregate Revolving Credit Exposure plus the aggregate principal
amount of outstanding Competitive Loans would exceed the Aggregate Revolving
Commitment.

         (e)   The Borrower shall notify the Administrative Agent of any
election to terminate or reduce the Revolving Commitments under paragraph (d) of
this Section 2.09 at least three Business Days prior to the effective date of
such termination or reduction, specifying such election and the effective date
thereof. Promptly following receipt of any notice, the Administrative Agent
shall advise the Revolving Lenders of the contents thereof. Each notice
delivered by the Borrower pursuant to this Section 2.09(e) shall be irrevocable;
provided that a notice of termination of the Revolving Commitments delivered by
the Borrower may state that such notice is conditioned upon the effectiveness of
other credit facilities, in which case such notice may be revoked by the
Borrower (by notice to the Administrative Agent on or prior to the specified
effective date) if such condition is not satisfied. Any termination or reduction
of the Revolving Commitments shall be permanent. Each reduction of the Revolving
Commitments shall be made ratably among the Revolving Lenders in accordance with
their respective Revolving Commitments.

     SECTION 2.10 Repayment of Loans; Evidence of Debt.

         (a)   The Borrower hereby unconditionally promises to pay (i) to the
Administrative Agent for the account of each Revolving Lender the then unpaid
principal amount of each Revolving Loan and Borrowing of such Revolving Lender
on the Revolving Commitment Termination Date, (ii) to the Administrative Agent
for the account of each Revolving Lender thereof, the then unpaid principal
amount of each Competitive Loan on the last day of the Interest Period
applicable to such Competitive Loan, (iii) to the Administrative Agent for the
account of each Term Lender, the then unpaid principal amount of each Term Loan
on the Term Maturity Date, and (iv) the amounts specified in Sections 2.08 and
2.11 on the dates specified in each such Section. The Borrower hereby further
agrees to pay interest on the unpaid principal amount of the Loans made to the
Borrower, from time to time outstanding from the date hereof until payment in
full thereof at the rates per annum, and on the dates set forth in Section 2.13.

         (b)   Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing the indebtedness of the Borrower to such
Lender resulting from each Loan made by such Lender, including the amounts of
principal and interest payable and paid to such Lender from time to time
hereunder.

         (c)   The Administrative Agent shall maintain accounts in which it
shall record (i) the amount of each Loan made hereunder, the Class and Type
thereof and the Interest Period applicable thereto, (ii) the amount of any
principal or interest due and payable or to become due and payable from the
Borrower to each Lender hereunder and (iii) the amount of any sum

                                                                              36

<PAGE>

received by the Administrative Agent hereunder for the account of the Lenders
and each Lender's share thereof.

         (d)   The entries made in the accounts maintained pursuant to paragraph
(b) or (c) of this Section 2.10 shall be prima facie evidence of the existence
and amounts of the obligations recorded therein; provided that the failure of
any Lender or the Administrative Agent to maintain such accounts or any error
therein shall not in any manner affect the obligation of the Borrower to repay
the Loans in accordance with the terms of this Agreement.

     SECTION 2.11 Prepayment of Loans; Application of Prepayments.

         (a)   In the event the Borrower shall, after the Revolving Commitment
Termination Date, receive Net Cash Proceeds from any Asset Disposition or Debt
Offering, such Net Cash Proceeds shall be applied on such date toward the
prepayment of the Loans as set forth in Section 2.11(e).

         (b)   The Borrower shall have the right at any time and from time to
time to prepay any Borrowing in whole or in part; provided that (i) each
prepayment pursuant to this Section 2.11(b) shall be in an amount that is an
integral multiple of $2,000,000 and not less than $10,000,000, (ii) each
prepayment pursuant to this Section 2.11(b) shall be subject to prior notice in
accordance with paragraph (d) of this Section 2.11, (iii) the Borrower shall pay
any and all costs and expenses due to the Lenders pursuant to Section 2.16 at
the time of such prepayment, and (iv) the Borrower shall not have the right to
prepay any Competitive Loan without the prior consent of the Revolving Lender
thereof.

         (c)   The Borrower shall, from time to time, upon demand of the
Administrative Agent, prepay the Revolving Loans in such amounts as shall be
necessary so that at all times the sum of the Aggregate Revolving Credit
Exposure plus the aggregate principal amount of outstanding Competitive Loans is
equal to or less than the Aggregate Revolving Commitment.

         (d)   The Borrower shall notify the Administrative Agent by telephone
(confirmed by telecopy) of any prepayment hereunder (i) in the case of
prepayment of a Eurodollar Borrowing, not later than 11:00 a.m., Dallas, Texas
time, three Business Days before the date of prepayment or (ii) in the case of
prepayment of an ABR Borrowing, not later than 11:00 a.m., Dallas, Texas time,
one Business Day before the date of prepayment. Each such notice shall be
irrevocable and shall specify the prepayment date and the principal amount of
each Borrowing or portion thereof to be prepaid (which amount shall be in a
minimum principal amount of $10,000,000 and in $2,000,000 increments in excess
thereof); provided that, if a notice of prepayment is given in connection with a
conditional notice of termination of the Revolving Commitments as contemplated
by Section 2.09(e), then such notice of prepayment may be revoked if such notice
of termination is revoked in accordance with Section 2.09(e). Promptly following
receipt of any such notice relating to a Borrowing, the Administrative Agent
shall advise the Lenders of the contents thereof. Each prepayment of a Borrowing
shall be applied ratably to the Loans included in the prepaid Borrowing.
Prepayments shall be accompanied by accrued interest to the extent required by
Section 2.13.

                                                                              37

<PAGE>

         (e)   Amounts to be applied in connection with prepayments and
Revolving Commitment reductions made pursuant to Section 2.09(c) and Section
2.11(a) shall be applied, first, to the prepayment of the Term Loans (applied
ratably to each of the scheduled principal installments due and owing pursuant
to Section 2.08(b) at the time of such prepayment), and second, to reduce
permanently the Revolving Commitments (as applicable), any such reduction to be
applied proportionately to the Revolving Commitment of each Revolving Lender.
Any such reduction of the Revolving Commitment shall be accompanied by a
prepayment of the Revolving Loans to the extent required by Section 2.11(c).
Subject to the terms hereof, each prepayment of Loans and reduction of the
Revolving Commitment shall be made ratably among the Lenders in accordance with
their Commitments. The application of any prepayment of the Loans shall be
applied first to ABR Loans and then to Eurodollar Loans next maturing.

     SECTION 2.12 Fees.

         (a)   The Borrower agrees to pay to the Administrative Agent for the
account of each Revolving Lender a facility fee, which shall accrue at the
Applicable Rate on the daily amount of the Revolving Commitment of such
Revolving Lender (whether used or unused) during the period from and including
the Effective Date to but excluding the Revolving Commitment Termination Date
applicable to such Revolving Lender's Revolving Commitment. Accrued facility
fees shall be payable in arrears on each Quarterly Date of each year and on the
Revolving Commitment Termination Date, commencing on the first such date to
occur after the Effective Date. All facility fees shall be computed on the basis
of a year of 360 days and shall be payable for the actual number of days elapsed
(including the first day but excluding the last day).

         (b)   The Borrower agrees to pay (i) to the Administrative Agent for
the account of each Revolving Lender a participation fee with respect to its
participations in Letters of Credit, which shall accrue at the same Applicable
Rate as interest on Eurodollar Revolving Loans on the average daily amount of
such Revolving Lender's LC Exposure (excluding any portion thereof attributable
to unreimbursed LC Disbursements) during the period from and including the
Effective Date to but excluding the later of the date on which such Revolving
Lender's Revolving Commitment terminates and the date on which such Revolving
Lender ceases to have any LC Exposure, and (ii) to the Issuing Bank upon
issuance of any Letter of Credit by such Issuing Bank a fronting fee equal to an
amount calculated at the rate of 0.125% per annum based on the stated amount and
term of such Letter of Credit, as well as the Issuing Bank's standard fees with
respect to the administration, issuance, amendment, renewal or extension of any
Letter of Credit or processing of drawings thereunder. Participation fees shall
be payable in arrears on the third Business Day following each Quarterly Date,
commencing on the first such date to occur after the Effective Date; provided
that all such fees shall be payable on the date on which the Revolving
Commitments terminate and any such fees accruing after the date on which the
Revolving Commitments terminate shall be payable on demand. Any other fees
payable to the Issuing Bank pursuant to this Section 2.12(b) shall be payable
within 10 days after demand. All participation fees and fronting fees shall be
computed on the basis of a year of 360 days and shall be payable for the actual
number of days elapsed (including the first day but excluding the last day).

                                                                              38

<PAGE>

         (c)   If the Utilization Percentage for any day is greater than 33%,
the Borrower shall pay to the Administrative Agent for the account of the
Revolving Lenders a utilization fee (the "Utilization Fee"), calculated at a
rate per annum equal to 0.125% (if the Utilization Percentage is greater than
33%, but less than or equal to 50%) or 0.250% (if the Utilization Percentage is
greater than 50%), multiplied by the daily Aggregate Revolving Credit Exposure
under this Agreement. If the Utilization Fee is owing, such fee shall be payable
by the Borrower in arrears on each Quarterly Date of each year and on the
Revolving Commitment Termination Date.

         (d)   The Borrower agrees to pay to the Administrative Agent, for its
own account, fees payable in the amounts and at the times separately agreed upon
in writing between the Borrower and the Administrative Agent (including, without
limitation, all fees due and payable pursuant to the terms of the Fee Letter).

         (e)   All fees payable hereunder shall be paid on the dates due, in
immediately available funds, to the Administrative Agent (or to the Issuing
Bank, in the case of fees payable to it) for distribution, in the case of
facility fees, participation fees and Utilization Fees, to the Revolving
Lenders. Fees paid shall not be refundable under any circumstances.

     SECTION 2.13 Interest.

         (a)   Subject to Section 10.13, the Loans comprising each ABR Borrowing
shall bear interest at the Alternate Base Rate.

         (b)   Subject to Section 10.13, the Loans comprising each Eurodollar
Borrowing shall bear interest (i) in the case of a Eurodollar Loan, at the
Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the
Applicable Rate, or (ii) in the case of a Eurodollar Competitive Loan, at the
LIBO Rate for the Interest Period in effect for such Borrowing plus (or minus,
as applicable) the Margin applicable to such Loan.

         (c)   Subject to Section 10.13, each Fixed Rate Loan shall bear
interest at the Fixed Rate applicable to such Loan.

         (d)   Notwithstanding the foregoing, but subject to Section 10.13, if
any principal of or interest on any Loan or any fee or other amount payable by
the Borrower hereunder is not paid when due, whether at stated maturity, upon
acceleration or otherwise, such overdue amount shall bear interest, after as
well as before judgment, at a rate per annum equal to (i) in the case of overdue
principal of any Loan, 2% plus the rate otherwise applicable to such Loan as
provided in the preceding paragraphs of this Section 2.13 or (ii) in the case of
any other amount, 2% plus the rate applicable to ABR Loans as provided in
paragraph (a) of this Section 2.13.

         (e)   Subject to Section 10.13, accrued interest on each Loan shall be
payable in arrears on each Interest Payment Date for such Loan; provided that
(i) interest accrued pursuant to paragraph (d) of this Section 2.13 shall be
payable on demand, (ii) in the event of any repayment or prepayment of any Loan
(other than a prepayment of an ABR Loan prior to the end

                                                                              39

of the Availability Period), accrued interest on the principal amount repaid or
prepaid shall be payable on the date of such repayment or prepayment and (iii)
in the event of any conversion of any Eurodollar Loan prior to the end of the
current Interest Period therefor, accrued interest on such Loan shall be payable
on the effective date of such conversion.

         (f)   Subject to Section 10.13, all interest hereunder shall be
computed on the basis of a year of 360 days, except that interest computed by
reference to the Alternate Base Rate at times when the Alternate Base Rate is
based on the Prime Rate shall be computed on the basis of a year of 365 days (or
366 days in a leap year), and in each case shall be payable for the actual
number of days elapsed (including the first day but excluding the last day). The
applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be
determined by the Administrative Agent, and such determination shall be
conclusive absent manifest error.

     SECTION 2.14 Alternate Rate of Interest. If prior to the commencement of
any Interest Period for a Eurodollar Borrowing:

         (a)   the Administrative Agent determines that adequate and reasonable
means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as
applicable, for such Interest Period;

         (b)   the Administrative Agent is advised by the Required Lenders (or,
in the case of a Eurodollar Competitive Loan, the Lender that is required to
make such Loan) that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for
such Interest Period will not adequately and fairly reflect the cost to such
Lenders (or Lender) of making or maintaining their Loans (or its Loan) included
in such Borrowing for such Interest Period; or

         (c)   the Administrative Agent determines that by reason of
circumstances affecting the interbank dollar market generally, deposits in U.S.
Dollars in the relevant interbank dollar market are not being offered for the
applicable Interest Period and in an amount equal to the amount of the
Eurodollar Loan requested by the Borrower;

then the Administrative Agent shall give notice thereof to the Borrower and the
Lenders by telephone or telecopy as promptly as practicable thereafter and,
until the Administrative Agent notifies the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, (i) any Interest
Election Request that requests the conversion of any Borrowing to, or
continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective,
(ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing
shall be made as an ABR Borrowing and (iii) any request by the Borrower for a
Eurodollar Competitive Borrowing shall be ineffective; provided that (A) if the
circumstances giving rise to such notice do not affect all the Lenders, then
requests by the Borrower for Eurodollar Competitive Borrowings may be made to
Lenders that are not affected thereby and (B) if the circumstances giving rise
to such notice affect only one Type of Borrowings, then the other Type of
Borrowings shall be permitted.

     SECTION 2.15 Increased Costs.

         (a) If any Change in Law shall:

                                                                              40

<PAGE>

               (i)   impose, modify or deem applicable any reserve, special
         deposit or similar requirement against assets of, deposits with or for
         the account of, or credit extended by, any Lender (except any such
         reserve requirement reflected in the Adjusted LIBO Rate) or the
         Issuing Bank; or

               (ii)  impose on any Lender or the Issuing Bank or the London
         interbank market any other condition affecting this Agreement or
         Eurodollar Loans or Fixed Rate Loans made by such Lender or any Letter
         of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurodollar Loan or Fixed Rate Loan (or of
maintaining its obligation to make any such Loan) or to increase the cost to
such Lender or the Issuing Bank of participating in, issuing or maintaining any
Letter of Credit or to reduce the amount of any sum received or receivable by
such Lender or the Issuing Bank hereunder (whether of principal, interest or
otherwise), then the Borrower will pay to such Lender or the Issuing Bank, as
the case may be, such additional amount or amounts as will compensate such
Lender or the Issuing Bank, as the case may be, for such additional costs
incurred or reduction suffered.

         (b)   If any Lender or the Issuing Bank determines that any Change in
Law regarding capital requirements has or would have the effect of reducing the
rate of return on such Lender's or the Issuing Bank's capital or on the capital
of such Lender's or the Issuing Bank's holding company, if any, as a consequence
of this Agreement or the Loans made by, or participations in Letters of Credit
held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a
level below that which such Lender or the Issuing Bank or such Lender's or the
Issuing Bank's holding company could have achieved but for such Change in Law
(taking into consideration such Lender's or the Issuing Bank's policies and the
policies of such Lender's or the Issuing Bank's holding company with respect to
capital adequacy), then from time to time the Borrower will pay to such Lender
or the Issuing Bank, as the case may be, such additional amount or amounts as
will compensate such Lender or the Issuing Bank or such Lender's or the Issuing
Bank's holding company for any such reduction suffered.

         (c)   A certificate of a Lender or the Issuing Bank setting forth the
amount or amounts necessary to compensate such Lender or the Issuing Bank or its
holding company, as the case may be, as specified in paragraph (a) or (b) of
this Section 2.15 shall be delivered to the Borrower and shall be conclusive
absent manifest error. The Borrower shall pay such Lender or the Issuing Bank,
as the case may be, the amount shown as due on any such certificate within 10
days after receipt thereof.

         (d)   Failure or delay on the part of any Lender or the Issuing Bank to
demand compensation pursuant to this Section 2.15 shall not constitute a waiver
of such Lender's or the Issuing Bank's right to demand such compensation;
provided that the Borrower shall not be required to compensate a Lender or the
Issuing Bank pursuant to this Section 2.15 for any increased costs or reductions
incurred more than 270 days prior to the date that such Lender or the Issuing
Bank, as the case may be, notifies the Borrower of the Change in Law giving rise
to such increased costs or reductions and of such Lender's or the Issuing Bank's
intention to claim compensation therefor; provided further that, if the Change
in Law giving rise to such increased

                                                                              41

<PAGE>

costs or reductions is retroactive, then the 270-day period referred to above
shall be extended to include the period of retroactive effect thereof.

         (e)   Notwithstanding the foregoing provisions of this Section 2.15, a
Lender shall not be entitled to compensation pursuant to this Section 2.15 in
respect of any Competitive Loan if the Change in Law that would otherwise
entitle it to such compensation shall have been publicly announced prior to
submission of the Competitive Bid pursuant to which such Loan was made.

     SECTION 2.16 Break Funding Payments. In the event of (a) the payment of any
principal of any Eurodollar Loan or Fixed Rate Loan other than on the last day
of an Interest Period applicable thereto (including as a result of an Event of
Default), (b) the conversion of any Eurodollar Loan other than on the last day
of the Interest Period applicable thereto, (c) the failure to borrow, convert,
continue or prepay any Loan on the date specified in any notice delivered
pursuant hereto (regardless of whether such notice may be revoked under Section
2.11(d) and is revoked in accordance therewith), (d) the failure to borrow any
Competitive Loan after accepting the Competitive Bid to make such Loan, or (e)
the assignment of any Eurodollar Loan or Fixed Rate Loan other than on the last
day of the Interest Period applicable thereto as a result of a request by the
Borrower pursuant to Section 2.20, then, in any such event, the Borrower shall
compensate each Lender for the loss, cost and expense attributable to such
event. In the case of a Eurodollar Loan, such loss, cost or expense to any
Lender shall be deemed to include an amount determined by such Lender to be the
excess, if any, of (i) the amount of interest which would have accrued on the
principal amount of such Loan had such event not occurred, at the Adjusted LIBO
Rate that would have been applicable to such Loan, for the period from the date
of such event to the last day of the then current Interest Period therefor (or,
in the case of a failure to borrow, convert or continue, for the period that
would have been the Interest Period for such Loan), over (ii) the amount of
interest which would accrue on such principal amount for such period at the
interest rate which such Lender would bid were it to bid, at the commencement of
such period, for dollar deposits of a comparable amount and period from other
banks in the eurodollar market. A certificate of any Lender setting forth any
amount or amounts that such Lender is entitled to receive pursuant to this
Section 2.16 shall be delivered to the Borrower and shall be conclusive absent
manifest error. The Borrower shall pay such Lender the amount shown as due on
any such certificate within 10 days after receipt thereof.

     SECTION 2.17 Taxes.

         (a)   Any and all payments by or on account of any obligation of the
Borrower hereunder shall be made free and clear of and without deduction for any
Indemnified Taxes or Other Taxes; provided that if the Borrower shall be
required to deduct any Indemnified Taxes or Other Taxes from such payments, then
(i) the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 2.17) the Administrative Agent, each Lender or the Issuing
Bank (as the case may be) receives an amount equal to the sum it would have
received had no such deductions been made, (ii) the Borrower shall make such
deductions and (iii) the Borrower shall pay the full amount deducted to the
relevant Governmental Authority in accordance with applicable law.

                                                                              42

<PAGE>

         (b)   In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

         (c)   The Borrower shall indemnify the Administrative Agent, each
Lender and the Issuing Bank, within 10 days after written demand therefor, for
the full amount of any Indemnified Taxes or Other Taxes paid by the
Administrative Agent, such Lender or the Issuing Bank, as the case may be, on or
with respect to any payment by or on account of any obligation of the Borrower
hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section 2.17) and any penalties,
interest and reasonable expenses arising therefrom or with respect thereto,
whether or not such Indemnified Taxes or Other Taxes were correctly or legally
imposed or asserted by the relevant Governmental Authority. A certificate as to
the amount of such payment or liability delivered to the Borrower by a Lender or
the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf
of a Lender or the Issuing Bank, shall be conclusive absent manifest error.

         (d)   As soon as practicable after any payment of Indemnified Taxes or
Other Taxes by the Borrower to a Governmental Authority, the Borrower shall
deliver to the Administrative Agent the original or a certified copy of a
receipt issued by such Governmental Authority evidencing such payment, a copy of
the return reporting such payment or other evidence of such payment reasonably
satisfactory to the Administrative Agent.

         (e)   Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which the
Borrower is located, or any treaty to which such jurisdiction is a party, with
respect to payments under this Agreement shall deliver to the Borrower (with a
copy to the Administrative Agent), at the time or times prescribed by applicable
law, such properly completed and executed documentation prescribed by applicable
law or reasonably requested by the Borrower as will permit such payments to be
made without withholding or at a reduced rate.

     SECTION 2.18 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

         (a)   The Borrower shall make each payment required to be made by it
hereunder (whether of principal, interest, fees or reimbursement of LC
Disbursements, or of amounts payable under Section 2.15, 2.16 or 2.17, or
otherwise) prior to 12:00 noon, Dallas, Texas time, on the date when due, in
immediately available funds, without set-off or counterclaim. Any amounts
received after such time on any date may, in the discretion of the
Administrative Agent, be deemed to have been received on the next succeeding
Business Day for purposes of calculating interest thereon. All such payments
shall be made to the Administrative Agent at its offices at 1 Chase Manhattan
Plaza, 8th Floor, New York, New York 10081, except payments to be made directly
to the Issuing Bank as expressly provided herein and except that payments
pursuant to Sections 2.15, 2.16, 2.17 and 10.03 shall be made directly to the
Persons entitled thereto. The Administrative Agent shall distribute any such
payments received by it for the account of any other Person to the appropriate
recipient promptly following receipt thereof. If any payment hereunder shall be
due on a day that is not a Business Day, the date for payment shall be extended
to the next succeeding Business Day, and, in the case of any payment accruing

                                                                              43

<PAGE>

interest, interest thereon shall be payable for the period of such extension.
All payments hereunder shall be made in dollars.

         (b)   Each Borrowing of Revolving Loans shall be made, each payment on
account of any facility fee, participation fee or Utilization Fee in respect of
the Revolving Commitments hereunder shall be allocated by the Administrative
Agent, and any reduction of the Revolving Commitments of the Revolving Lenders
shall be allocated by the Administrative Agent, pro rata according to the
relevant Revolving Credit Percentages of the Revolving Lenders. Each payment
(including each prepayment) on account of principal of and interest on any
Revolving Loans shall be allocated by the Administrative Agent pro rata
according to the respective outstanding principal amounts of such Revolving
Loans then held by the Revolving Lenders. Each payment (including each
prepayment) on account of principal of and interest on any Term Loans shall be
allocated by the Administrative Agent pro rata according to the respective
outstanding principal amounts of such Term Loans then held by the Term Lenders.
Further, if at any time insufficient funds are received by and available to the
Administrative Agent to pay fully all amounts of principal, unreimbursed LC
Disbursements, interest and fees then due hereunder, such funds shall be applied
(i) first, towards payment of interest and fees then due hereunder, ratably
among the parties entitled thereto in accordance with the amounts of interest
and fees then due to such parties, and (ii) second, towards payment of principal
and unreimbursed LC Disbursements then due hereunder, ratably among the parties
entitled thereto in accordance with the amounts of principal and unreimbursed LC
Disbursements then due to such parties. All proceeds (including proceeds from
the realization upon the Collateral) received after acceleration of the maturity
of the Loans, shall be applied first, to reimbursement of expenses and
indemnities provided for in this Agreement and the other Loan Documents, second,
to the other Lender Indebtedness until repaid in full pro rata to each Lender,
and third, to any other Person entitled to receive such proceeds in accordance
with applicable law.

         (c)   If any Lender shall, by exercising any right of set-off or
counterclaim or otherwise, obtain payment in respect of any principal of or
interest on any of its Loans or participations in LC Disbursements resulting in
such Lender receiving payment of a greater proportion of the aggregate amount of
its Loans and participations in LC Disbursements and accrued interest thereon
than the proportion received by any other Lender, then the Lender receiving such
greater proportion shall purchase (for cash at face value) participations in the
Loans and participations in LC Disbursements of other Lenders to the extent
necessary so that the benefit of all such payments shall be shared by the
Lenders ratably in accordance with the aggregate amount of principal of and
accrued interest on their respective Loans and participations in LC
Disbursements; provided that (i) if any such participations are purchased and
all or any portion of the payment giving rise thereto is recovered, such
participations shall be rescinded and the purchase price restored to the extent
of such recovery, without interest, unless the Lender from which such payment is
recovered is required to pay interest thereon, in which case each Lender
returning funds to such Lender shall pay its pro rata share of such interest,
and (ii) the provisions of this Section 2.18(c) shall not be construed to apply
to any payment made by the Borrower pursuant to and in accordance with the
express terms of this Agreement or any payment obtained by a Lender as
consideration for the assignment of or sale of a participation in any of its
Loans or participations in LC Disbursements to any assignee or participant,
other than to the Borrower or any Subsidiary or Affiliate thereof (as to which
the provisions of this

                                                                              44

<PAGE>

Section 2.18(c) shall apply). The Borrower consents to the foregoing and agrees,
to the extent it may effectively do so under applicable law, that any Lender
acquiring a participation pursuant to the foregoing arrangements may exercise
against the Borrower rights of set-off and counterclaim with respect to such
participation as fully as if such Lender were a direct creditor of the Borrower
in the amount of such participation.

         (d)   Unless the Administrative Agent shall have received notice from
the Borrower prior to the date on which any payment is due to the Administrative
Agent for the account of the Lenders or the Issuing Bank hereunder that the
Borrower will not make such payment, the Administrative Agent may assume that
the Borrower has made such payment on such date in accordance herewith and may,
in reliance upon such assumption, distribute to the Lenders or the Issuing Bank,
as the case may be, the amount due. In such event, if the Borrower has not in
fact made such payment, then each of the Lenders or the Issuing Bank, as the
case may be, severally agrees to repay to the Administrative Agent forthwith on
demand the amount so distributed to such Lender or Issuing Bank with interest
thereon, for each day from and including the date such amount is distributed to
it to but excluding the date of payment to the Administrative Agent, at the
greater of the Federal Funds Effective Rate and a rate determined by the
Administrative Agent in accordance with banking industry rules on interbank
compensation.

         (e)   If any Lender shall fail to make any payment required to be made
by it pursuant to Section 2.05(d) or (e), 2.06(b), 2.18(d) or 10.03(e), then the
Administrative Agent may, in its discretion (notwithstanding any contrary
provision hereof), apply any amounts thereafter received by the Administrative
Agent for the account of such Lender to satisfy such Lender's obligations under
such Sections until all such unsatisfied obligations are fully paid.

     SECTION 2.19 Illegality.

         (a)   Notwithstanding any other provision of this Agreement to the
contrary, if (i) by reason of the adoption of any applicable Governmental Rule
or any change (after the Effective Date) in any applicable Governmental Rule or
in the interpretation or administration thereof by any Governmental Authority or
compliance by any Lender with any request or directive (whether or not having
the force of law) of any central bank or other Governmental Authority or (ii)
circumstances affecting the London interbank dollar market or the position of a
Lender therein shall at any time make it unlawful or impracticable in the sole
discretion of a Lender exercised in good faith for such lender or its applicable
lending office to (A) honor its obligation to make Eurodollar Loans either
generally or for a particular Interest Period provided for hereunder, or (B)
maintain Eurodollar Loans either generally or for a particular Interest Period
provided for hereunder, then such Lender shall promptly notify the Borrower
thereof through the Administrative Agent and such Lender's obligation to make or
maintain Eurodollar Loans having an affected Interest Period hereunder shall be
suspended until such time as such Lender may again make and maintain Eurodollar
Loans having an affected Interest Period (in which case the provisions of
Section 2.19(b) hereof shall be applicable). Before giving such notice pursuant
to this Section 2.19(a), such Lender will designate a different available
lending office for the affected Eurodollar Loans of such Lender or take such
other action as the Borrower may request if such designation or action will
avoid the need to suspend such Lender's obligation to make Eurodollar Loans
hereunder and will not, in the sole opinion of such Lender exercised in good

                                                                              45

<PAGE>

faith, be disadvantageous to such Lender (provided, that such Lender shall have
no obligation to so designate a lending office for Eurodollar Loans located in
the United States of America).

         (b)   If the obligation of any Lender to make or maintain any
Eurodollar Loans shall be suspended pursuant to Section 2.19(a) hereof, all
Loans having an affected Interest Period which would otherwise be made by such
Lender as Eurodollar Loans shall be made instead as ABR Loans (and, if such
Lender so requests by notice to the Borrower with a copy to the Administrative
Agent, each Eurodollar Loan having an affected Interest Period of such Lender
then outstanding shall be automatically converted into an ABR Loan on the last
day of the Interest Period for such Eurodollar Loans unless earlier conversion
is required by applicable law) and, to the extent that Eurodollar Loans are so
made as (or converted into) ABR Loans, all payments of principal which would
otherwise be applied to such Eurodollar Loans shall be applied instead to such
ABR Loans.

     SECTION 2.20 Mitigation Obligations; Replacement of Lenders.

         (a)   If any Lender requests compensation under Section 2.15, or if the
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.17,
then such Lender shall use reasonable efforts to designate a different lending
office for funding or booking its Loans hereunder or to assign its rights and
obligations hereunder to another of its offices, branches or affiliates, if, in
the judgment of such Lender, such designation or assignment (i) would eliminate
or reduce amounts payable pursuant to Section 2.15 or 2.17, as the case may be,
in the future and (ii) would not subject such Lender to any unreimbursed cost or
expense and would not otherwise be disadvantageous to such Lender. The Borrower
hereby agrees to pay all reasonable costs and expenses incurred by any Lender in
connection with any such designation or assignment.

         (b)   If (i) any Lender requests compensation under Section 2.15, (ii)
the Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.17,
(iii) any Lender defaults in its obligation to fund Loans hereunder, or (iv) any
Lender suspends its obligation to maintain or fund Eurodollar Loans under
Section 2.19, then the Borrower may, at its sole expense and effort, upon notice
to such Lender and the Administrative Agent, require such Lender to assign and
delegate, without recourse (in accordance with and subject to the restrictions
contained in Section 10.04), all its interests, rights and obligations under
this Agreement (other than any outstanding Competitive Loans held by it) to an
assignee that shall assume such obligations (which assignee may be another
Lender, if a Lender accepts such assignment); provided that (i) the Borrower
shall have received the prior written consent of the Administrative Agent (and,
if a Revolving Commitment is being assigned, the Issuing Bank), which consent
shall not unreasonably be withheld, (ii) such Lender shall have received payment
of an amount equal to the outstanding principal of its Loans (other than
Competitive Loans) and participations in LC Disbursements, accrued interest
thereon, accrued fees and all other amounts payable to it hereunder, from the
assignee (to the extent of such outstanding principal and accrued interest and
fees) or the Borrower (in the case of all other amounts) and (iii) in the case
of any such assignment resulting from a claim for compensation under Section
2.15 or payments required to be made pursuant to Section 2.17, such assignment
will result in a reduction in such compensation or payments. A

                                                                              46

<PAGE>

Lender shall not be required to make any such assignment and delegation if,
prior thereto, as a result of a waiver by such Lender or otherwise, the
circumstances entitling the Borrower to require such assignment and delegation
cease to apply.

                                  ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

         In order to induce the Administrative Agent, the Syndication Agents,
the Issuing Bank and the Lenders to enter into this Agreement and to make Loans
and issue Letters of Credit hereunder, the Borrower represents and warrants to
the Agents, the Issuing Bank and the Lenders that:

     SECTION 3.01 Organization; Powers. Each of the Borrower and its
Consolidated Subsidiaries is duly organized, validly existing and in good
standing under the laws of the jurisdiction of its organization, has all
requisite power and authority to carry on its business as now conducted and,
except where the failure to do so, individually or in the aggregate, could not
reasonably be expected to result in a Material Adverse Effect, is qualified to
do business in, and is in good standing in, every jurisdiction where such
qualification is required.

     SECTION 3.02 Authorization; Enforceability. The Transactions are within the
Borrower's and each Material Subsidiary's corporate, partnership or limited
liability company powers (as applicable) and have been duly authorized by all
necessary corporate, partnership or limited liability company powers (as
applicable) and, if required, stockholder action. This Agreement and the other
Loan Documents have been duly executed and delivered by the Borrower and each
Material Subsidiary (to the extent a party thereto) and constitute the legal,
valid and binding obligations of the Borrower and each Material Subsidiary (as
applicable), enforceable in accordance with their respective terms, subject to
applicable bankruptcy, insolvency, reorganization, moratorium or other laws
affecting creditors' rights generally and subject to general principles of
equity, regardless of whether considered in a proceeding in equity or at law.

     SECTION 3.03 Governmental Approvals; No Conflicts. The Transactions (a) do
not require any consent or approval of, registration or filing with, or any
other action by, any Governmental Authority, except such as have been obtained
or made and are in full force and effect, (b) will not violate any applicable
law or regulation or the charter, by-laws or other organizational documents of
the Borrower or any of its Subsidiaries or any order of any Governmental
Authority, (c) will not violate or result in a default under any indenture,
agreement or other instrument binding upon the Borrower or any of its
Subsidiaries or its assets, or give rise to a right thereunder to require any
payment to be made by the Borrower or any of its Subsidiaries, and (d) will not
result in the creation or imposition of any Lien on any asset of the Borrower or
any of its Subsidiaries.

     SECTION 3.04 Financial Condition; No Material Adverse Change.

         (a)   The Borrower has heretofore furnished to the Lenders its
consolidated balance sheet and statements of income, stockholders equity and
cash flows (i) as of and for the

                                                                              47

<PAGE>

calendar year ended December 31, 2001, audited by Ernst & Young, LLP,
independent public accountants, and (ii) as of and for the Fiscal Quarter and
the portion of the calendar year ended March 31, 2002, certified by one of its
Financial Officers. Such financial statements present fairly, in all material
respects, the financial position and results of operations and cash flows of the
Borrower and its Consolidated Subsidiaries as of such dates and for such periods
in accordance with GAAP, subject to year-end audit adjustments and the absence
of footnotes in the case of the statements referred to in clause (ii) above.

         (b)   Since December 31, 2001, and except for the Disclosed Matters,
there has been no Material Adverse Effect on the Borrower and its Subsidiaries,
taken as a whole.

     SECTION 3.05 Properties.

         (a)   Each of the Borrower and its Consolidated Subsidiaries has good
title to, or valid leasehold interests in, all its Property material to its
business (including its Collateral), except for (i) Permitted Encumbrances and
(ii) minor defects in title that do not interfere with its ability to conduct
its business as currently conducted or to utilize such properties for their
intended purposes.

         (b)   Each of the Borrower and its Consolidated Subsidiaries owns, or
is licensed to use, all trademarks, tradenames, copyrights, patents and other
intellectual property material to its business (including its Collateral), and
the use thereof by the Borrower and its Consolidated Subsidiaries does not
infringe upon the rights of any other Person, except for any such infringements
that, individually or in the aggregate, could not reasonably be expected to
result in a Material Adverse Effect.

     SECTION 3.06 Litigation.

         (a)   There are no actions, suits or proceedings by or before any
arbitrator or Governmental Authority pending against or, to the knowledge of the
Borrower, threatened against or affecting the Borrower or any of its
Subsidiaries (i) as to which there is a reasonable possibility of an adverse
determination and that, if adversely determined, could reasonably be expected,
individually or in the aggregate, to result in a Material Adverse Effect (other
than the Disclosed Matters) or (ii) that involve this Agreement or the
Transactions.

         (b)   Since the date of this Agreement, there has been no change in the
status of the Disclosed Matters that, individually or in the aggregate, has
resulted in, or materially increased the likelihood of, a Material Adverse
Effect.

     SECTION 3.07 Compliance with Laws and Agreements. Each of the Borrower and
its Subsidiaries is in compliance with all laws, regulations and orders of any
Governmental Authority applicable to it or its property and all indentures,
agreements and other instruments binding upon it or its property, except where
the failure to do so, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect. Neither (a) a Default nor (b)
any other default by the Borrower or any of its Subsidiaries under any agreement
that could result in a Material Adverse Effect, has occurred and is continuing.

                                                                              48

<PAGE>

     SECTION 3.08 Investment and Holding Company Status. Neither the Borrower
nor any of its Subsidiaries is (a) an "investment company" as defined in, or
subject to regulation under, the Investment Company Act of 1940 or (b) a
"holding company" as defined in, or subject to regulation under, the Public
Utility Holding Company Act of 1935.

     SECTION 3.09 Taxes. Each of the Borrower and its Subsidiaries has timely
filed or caused to be filed all Tax returns and reports required to have been
filed and has paid or caused to be paid all Taxes required to have been paid by
it, except (a) Taxes that are being contested in good faith by appropriate
proceedings and for which the Borrower or such Subsidiary, as applicable, has
set aside on its books adequate reserves or (b) to the extent that the failure
to do so could not reasonably be expected to result in a Material Adverse
Effect.

     SECTION 3.10 ERISA. No ERISA Event has occurred or is reasonably expected
to occur that, when taken together with all other such ERISA Events for which
liability is reasonably expected to occur, could reasonably be expected to
result in a Material Adverse Effect. The present value of all accumulated
benefit obligations under each Plan (in each case determined based on the
assumptions used for purposes of Statement of Financial Accounting Standards No.
87) as of the date of the most recent financial statements reflecting such
amounts, does not exceed the fair market value of the assets of such Plan (as of
the date of determination of such benefit obligation amount) by an amount which,
if it constituted a direct liability of the Borrower, could reasonably be
expected to have a Material Adverse Effect.

     SECTION 3.11 Subsidiaries. Schedule 3.11 hereto accurately (a) reflects
(i) the jurisdiction of incorporation or organization of the Borrower and each
of its Subsidiaries, and (ii) each jurisdiction in which the Borrower and each
of its Subsidiaries is qualified to transact business as a foreign corporation,
foreign partnership or foreign limited liability company, and (b) specifies
those Subsidiaries that are Material Subsidiaries. The Borrower has no
Subsidiaries other than those listed on Schedule 3.11.

     SECTION 3.12 Burdensome Obligations. Neither the Borrower nor any of its
Subsidiaries, nor any of their respective properties, is subject to any law or
any pending or threatened Change in Law or subject to any restriction under its
articles or certificate of incorporation, bylaws, regulations, partnership
agreement or comparable charter or other organizational documents or under any
agreement or instrument to which the Borrower or any of its Subsidiaries, or any
of their respective properties, may be subject or bound, which is so unusual or
burdensome as to be likely in the foreseeable future to result in a Material
Adverse Effect.

     SECTION 3.13 Employee Matters. Except as set forth on Schedule 3.13,
neither the Borrower nor any of its Subsidiaries, nor any of their respective
employees, is subject to any collective bargaining agreement. There are no
strikes, slowdowns, work stoppages or controversies pending or, to the knowledge
of the Borrower, threatened against the Borrower or any of its Subsidiaries, or
their respective employees, which could reasonably be expected to have a
Material Adverse Effect.

                                                                              49

<PAGE>

     SECTION 3.14 Disclosure. The Borrower has disclosed to the Lenders all
agreements, instruments and corporate or other restrictions to which it or any
of its Subsidiaries is subject, and all other matters known to it, that,
individually or in the aggregate, could reasonably be expected to result in a
Material Adverse Effect. Neither the Information Memorandum, nor any of the
other reports, financial statements, certificates or other information furnished
by or on behalf of the Borrower to the Administrative Agent or any Lender in
connection with the negotiation of this Agreement or delivered hereunder (as
modified or supplemented by other information so furnished) contains any
material misstatement of fact or omits to state any material fact necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading; provided that, with respect to projected financial
information, the Borrower represents only that such information was prepared in
good faith based upon assumptions believed to be reasonable at the time.

     SECTION 3.15 Margin Stock. None of the proceeds of the Loans will be used
for the purpose of, and neither the Borrower nor any Subsidiary of the Borrower
is engaged in the business of, extending credit for the purpose of (a)
purchasing or carrying any "margin stock" as defined in Regulation U of the
Board of Governors of the Federal Reserve System (12 C.F.R. Part 221) or (b)
reducing or retiring any indebtedness which was originally incurred to purchase
or carry any margin stock, in either case in violation of Regulation U. Neither
the Borrower nor any Subsidiary of the Borrower is engaged principally in the
business of extending credit for the purpose of purchasing or carrying any
margin stock. Neither the Borrower nor any Subsidiary of the Borrower nor any
Person acting on behalf of the Borrower or any Subsidiary of the Borrower has
taken or will take any action which would cause any of the Loan Documents,
including this Agreement and any Subsidiary Guaranty, to violate Regulation U or
any other regulation of the Board of Governors of the Federal Reserve System, or
to violate any similar provision of the Securities Exchange Act of 1934 or any
rule or regulation under any such provision thereof.

     SECTION 3.16 Primary Business. The primary business of the Borrower and its
Subsidiaries taken as a whole is that of the manufacturing of transportation,
construction and industrial products, and the leasing of railroad tank cars,
covered hopper cars, box cars and related equipment.

     SECTION 3.17 Environmental Matters.

         (a)   Except for the Disclosed Matters and except with respect to any
other matters that, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect, neither the Borrower nor any of
its Subsidiaries (i) has failed to comply with any Environmental Law or to
obtain, maintain or comply with any permit, license or other approval required
under any Environmental Law, (ii) has become subject to any Environmental
Liability, (iii) has received notice of any claim with respect to any
Environmental Liability or (iv) knows of any basis for any Environmental
Liability.

         (b)   Except for the Disclosed Matters, all Hazardous Materials or
solid waste generated at any and all Property of the Borrower or any Subsidiary
have in the past been transported, treated and disposed of only by carriers
maintaining valid

                                                                              50

<PAGE>

permits under any Environmental Law, and only at treatment, storage and disposal
facilities maintaining valid permits under any Environmental Law, which carriers
and facilities have been and are operating in compliance with such permits.

         (c)   The Borrower and each Subsidiary have taken all reasonable steps
necessary to determine and have determined that no Hazardous Materials or solid
waste has been disposed of or otherwise released and there has been no
threatened release of any Hazardous Materials on or to any Property of the
Borrower or any Subsidiary except in compliance with Environmental Laws, and
except for releases that, individually or in the aggregate, could not reasonably
be expected to result in a Material Adverse Effect.

     SECTION 3.18 Perfection Certificate; Real Property. Schedule 5 hereto
accurately reflects, as of the date hereof and as of the Post-Closing Date, the
location and value of certain of the Borrower's and its Subsidiaries' Property

All other information in the Perfection Certificate is true, correct and
complete in all material respects.

     SECTION 3.19 Schedules to other Loan Documents. All information set forth

Commitments, and thereupon the Commitments shall terminate immediately, and (ii)
declare the Loans then outstanding to be due and payable in whole (or in part,

and payable immediately, without presentment, demand, protest or other notice of
any kind, all of which are hereby waived by the Borrower; and in case of any
event with respect to the Borrower described in clause (h) or (i) of this
Article VIII, the Commitments shall automatically terminate and the principal of
the Loans then outstanding, together with accrued interest thereon and all fees
and other obligations of the Borrower accrued hereunder, shall automatically
become due and payable, without presentment, demand, protest or other notice of

Agent under the Security Agreements, the Pledge Agreements, the Mortgages and

                                     AGENTS

         Each of the Lenders, the Issuing Bank and the other Agents hereby
irrevocably appoint JPMorgan Chase Bank as Administrative Agent, and each of
Dresdner Bank AG, New York and Grand Cayman Branches and The Royal Bank of
Scotland plc as Syndication Agents, and authorize each such Agent to take such
actions on its behalf and to exercise such powers as are delegated to such
Agents by the terms of the Loan Documents, together with such actions and powers
as are reasonably incidental thereto. Without limiting the foregoing, the
Administrative Agent is hereby authorized to execute and deliver the
Intercreditor Agreement on behalf of each

                                                                              69
<PAGE>
Lender and bind each Lender to the terms thereof as if each Lender were directly
a party thereto. Further, each Lender hereby irrevocably appoints JPMorgan Chase
Bank as Collateral Agent for the Lenders under the Intercreditor Agreement and
the Security Instruments (as applicable).

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

         The Agents shall not have any duties or obligations except those
expressly set forth in the Loan Documents. Without limiting the generality of
the foregoing, (a) the Agents shall not be subject to any fiduciary or other
implied duties, regardless of whether a Default has occurred and is continuing,
(b) each Agent shall not have any duty to take any discretionary action or
exercise any discretionary powers, except discretionary rights and powers
expressly contemplated by the Loan Documents that such Agent is required to
exercise in writing by the Required Lenders (or such other number or percentage
of the Lenders as shall be necessary under the circumstances as provided in
Section 10.02, or further, with respect to the Collateral Agent, such other
number or percentage of Persons as necessary or required by the terms of the
Intercreditor Agreement), and (c) except as expressly set forth in the Loan
Documents, the Agents shall not have any duty to disclose, and shall not be
liable for the failure to disclose, any information relating to the Borrower or
any of its Subsidiaries that is communicated to or obtained by the bank serving
as such Agent or any of its Affiliates in any capacity. Each Agent shall not be
liable for any action taken or not taken by it with the consent or at the
request of the Required Lenders (or such other number or percentage of the
Lenders as shall be necessary under the circumstances as provided in Section
10.02) or in the absence of its own gross negligence or willful misconduct;
PROVIDED, HOWEVER, THAT IT IS THE INTENTION OF THE PARTIES HERETO THAT EACH OF
THE AGENTS BE INDEMNIFIED IN THE CASE OF ITS OWN NEGLIGENCE (OTHER THAN GROSS
NEGLIGENCE), REGARDLESS OF WHETHER SUCH NEGLIGENCE IS SOLE OR CONTRIBUTORY,
ACTIVE OR PASSIVE, IMPUTED, JOINT OR TECHNICAL. Each Agent shall be deemed not
to have knowledge of any Default (other than, with respect to the Administrative
Agent, knowledge of a Default of the types specified in clauses (a) or (b) of
Article VIII) unless and until written notice thereof is given to such Agent by
the Borrower or a Lender, and such Agent shall not be responsible for or have
any duty to ascertain or inquire into (i) any statement, warranty or
representation made in or in connection with any Loan Document, (ii) the
contents of any certificate, report or other document delivered hereunder or in
connection herewith, (iii) the performance or observance of any of the
covenants, agreements or other terms or conditions set forth in any Loan
Document, (iv) the validity, enforceability, effectiveness or genuineness of any
Loan Document or any other agreement, instrument or document, or (v) the
satisfaction of any condition set forth in Article IV or elsewhere in any Loan
Document, other than to confirm receipt of items expressly required to be
delivered to such Agent.

         The Agents shall be entitled to rely upon, and shall not incur any
liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing believed by it to be genuine
and to have been signed or sent by the proper Person. The

                                                                              70
<PAGE>
Agents also may rely upon any statement made to it orally or by telephone and
believed by it to be made by the proper Person, and shall not incur any
liability for relying thereon. The Agents may consult with legal counsel (who
may be counsel for the Borrower), independent accountants and other experts
selected by it, and shall not be liable for any action taken or not taken by it
in accordance with the advice of any such counsel, accountants or experts.

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

         Subject to the appointment and acceptance of a successor Administrative
Agent as provided in this paragraph, the Administrative Agent may resign at any
time by notifying the Lenders, the Issuing Bank and the Borrower. Upon any such
resignation, the Required Lenders shall have the right, in consultation with the
Borrower, to appoint a successor. If no successor shall have been so appointed
by the Required Lenders and shall have accepted such appointment within 30 days
after the retiring Administrative Agent gives notice of its resignation, then
the retiring Administrative Agent may, on behalf of the Lenders and the Issuing
Bank, appoint a successor Administrative Agent which shall be a bank with an
office in Dallas, Texas, Houston, Texas or New York City, or an Affiliate of any
such bank. Upon the acceptance of its appointment as Administrative Agent
hereunder by a successor, such successor shall succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder. The fees payable by the Borrower to a successor
Administrative Agent shall be the same as those payable to its predecessor
unless otherwise agreed between the Borrower and such successor. After the
Administrative Agent's resignation hereunder, the provisions of this Article and
Section 10.03 shall continue in effect for the benefit of such retiring
Administrative Agent, its sub-agents and their respective Related Parties in
respect of any actions taken or omitted to be taken by any of them while it was
acting as Administrative Agent.

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

                                                                              71

     SECTION 10.02 Waivers; Amendments.

         (a) No failure or delay by the Administrative Agent, the Issuing Bank
or any Lender in exercising any right or power hereunder or under any other Loan
Document shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right or power, or any abandonment or discontinuance of
steps to enforce such a right or power, preclude any other or further exercise
thereof or the exercise of any other right or power. The rights and remedies of
the Administrative Agent, the Issuing Bank and the Lenders hereunder and under
the other Loan Documents are cumulative and are not exclusive of any rights or
remedies that they would otherwise have. No waiver of any provision of this
Agreement or any other Loan Document or consent to any departure by the Borrower
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section 10.02, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given.
Without limiting the generality of the foregoing, the making of a Loan or
issuance of a Letter of Credit shall not be construed as a waiver of any
Default, regardless of whether the Administrative Agent, any Lender or the
Issuing Bank may have had notice or knowledge of such Default at the time.

                                                                              72
<PAGE>
         (b) Neither this Agreement nor any of the Loan Documents nor any
provision hereof or thereof may be waived, amended or modified except pursuant
to an agreement or agreements in writing entered into by the Borrower and the
Required Lenders or by the Borrower and the Administrative Agent with the
consent of the Required Lenders; provided that no such agreement shall (i)
increase the Commitment of any Lender without the written consent of such
Lender, (ii) reduce the principal amount of any Loan or LC Disbursement or
reduce the rate of interest thereon, or reduce any fees payable hereunder,
without the written consent of each Lender affected thereby, (iii) postpone the
scheduled date of payment of the principal amount of any Loan or LC
Disbursement, or any interest thereon, or any fees payable hereunder, or reduce
the amount of, waive or excuse any such payment, or postpone the scheduled date
of expiration of any Commitment, without the written consent of each Lender
affected thereby, (iv) change Section 2.18(b) or (c) in a manner that would
alter the pro rata sharing of payments required thereby, without the written
consent of each Lender directly affected thereby, (v) release any Material
Subsidiary from its obligations under its Subsidiary Guaranty, without the
written consent of each Lender, (vi) release any material portion of the
Collateral without the written consent of each Lender and each party otherwise
required to consent thereto pursuant to the terms of the Intercreditor
Agreement, except as otherwise expressly permitted hereby, and provided that the
Administrative Agent and the Collateral Agent shall release (without consent
from the Lenders or any other Person) any Collateral sold, transferred or
otherwise disposed of as permitted by Section 7.03 hereof, (vii) waive any of
the conditions set forth in Section 4.01 to the making of the Loans without the
consent of each Lender affected thereby, or (viii) change any of the provisions
of this Section 10.02(b) or the definition of "Required Lenders," "Required
Revolving Lenders" or "Required Term Lenders" or any other provision hereof
specifying the number or percentage of Lenders required to waive, amend or
modify any rights hereunder or make any determination or grant any consent
hereunder, without the written consent of each Lender directly affected thereby;
provided further that no such agreement shall amend, modify or otherwise affect
the rights or duties of any Agent or the Issuing Bank hereunder without the
prior written consent of such Agent or the Issuing Bank, as the case may be.
Further, to the extent any contemplated or proposed waiver, amendment or
modification affects only Revolving Loans and/or Revolving Lenders, or only Term
Loans and/or Term Lenders, any such waiver, amendment or modification may be
effectuated with the consent of the requisite number of Revolving Lenders or
Term Lenders, as the case may be, affected thereby, in accordance with the
provisions of this Section 10.2(b).

     SECTION 10.03 Expenses; Indemnity; Damage Waiver.

         (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses
incurred by the Administrative Agent, the Arranger and their respective
Affiliates, including the reasonable fees, charges and disbursements of counsel
for the Administrative Agent, in connection with the syndication of the credit
facilities provided for herein, the preparation and administration of this
Agreement and the other Loan Documents or any amendments, modifications or
waivers of the provisions hereof or thereof (whether or not the transactions
contemplated hereby or thereby shall be consummated), (ii) all reasonable
out-of-pocket expenses incurred by the Issuing Bank in connection with the
issuance, amendment, renewal or extension of any Letter of Credit or any demand
for payment thereunder and (iii) all out-of-pocket expenses incurred by the
Agents, the Issuing Bank or any Lender, including the fees,

                                                                              73
<PAGE>
charges and disbursements of any counsel for the Agents, the Issuing Bank or any
Lender, in connection with the enforcement or protection of its rights in
connection with this Agreement and the other Loan Documents, including its
rights under this Section 10.03, or in connection with the Loans made or Letters
of Credit issued hereunder, including all such out-of-pocket expenses incurred
during any workout, restructuring or negotiations in respect of such Loans or
Letters of Credit.

         (b) The Borrower shall indemnify the Agents, the Issuing Bank, the
Arranger and each Lender, and each Related Party of any of the foregoing Persons
(each such Person being called an "Indemnitee") against, and hold each
Indemnitee harmless from, any and all losses, claims, damages, liabilities and
related expenses, including the fees, charges and disbursements of any counsel
for any Indemnitee, incurred by or asserted against any Indemnitee arising out
of, in connection with, or as a result of (i) the execution or delivery of this
Agreement or any other Loan Document, the performance by the parties to the Loan
Documents of their respective obligations hereunder or the consummation of the
Transactions or any other transactions contemplated hereby, (ii) any Loan or
Letter of Credit or the use of the proceeds therefrom (including any refusal by
the Issuing Bank to honor a demand for payment under a Letter of Credit if the
documents presented in connection with such demand do not strictly comply with
the terms of such Letter of Credit), (iii) any actual or alleged presence or
release of Hazardous Materials on or from any property owned or operated by the
Borrower or any of its Subsidiaries, or any Environmental Liability related in
any way to the Borrower or any of its Subsidiaries, or (iv) any actual or
prospective claim, litigation, investigation or proceeding relating to any of
the foregoing, whether based on contract, tort or any other theory and
regardless of whether any Indemnitee is a party thereto; provided that such
indemnity shall not, as to any Indemnitee, be available to the extent that such
losses, claims, damages, liabilities or related expenses resulted from the gross
negligence or willful misconduct of such Indemnitee (IT BEING UNDERSTOOD THAT IT
IS THE INTENTION OF THE PARTIES HERETO THAT EACH OF THE INDEMNITEES BE
INDEMNIFIED IN THE CASE OF ITS OWN NEGLIGENCE (OTHER THAN GROSS NEGLIGENCE),
REGARDLESS OF WHETHER SUCH NEGLIGENCE IS SOLE OR CONTRIBUTORY, ACTIVE OR
PASSIVE, IMPUTED, JOINT OR TECHNICAL). No Indemnitee shall be liable for any
damages arising from the use by others of any information or other material
obtained through the Internet, Intralinks or other similar information
transmission systems in connection with the Loan Documents. The Borrower agrees
that no Indemnitee shall have any liability for any indirect or consequential
damages in connection with its activities related to the Loan Documents.

         (c) To the extent that the Borrower fails to pay any amount required to
be paid by it to the Agents or the Issuing Bank under paragraph (a) or (b) of
this Section 10.03, each Lender severally agrees to pay to such Agents or the
Issuing Bank, as the case may be, such Lender's Applicable Percentage
(determined as of the time that the applicable unreimbursed expense or indemnity
payment is sought) of such unpaid amount; provided that the unreimbursed expense
or indemnified loss, claim, damage, liability or related expense, as the case
may be, was incurred by or asserted against the Agents or the Issuing Bank in
its capacity as such.

         (d) To the extent permitted by applicable law, the Borrower shall not

indirect, consequential or punitive damages (as opposed to direct or actual
damages) arising out of, in connection with, or as a result of, this Agreement
or any agreement or instrument contemplated hereby, any other Loan Document, the
Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

         (e) All amounts due under this Section 10.03 shall be payable promptly
after written demand therefor.

     SECTION 10.04 Successors and Assigns.

         (a) The provisions of this Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns
permitted hereby (including any Affiliate of the Issuing Bank that issues any
Letter of Credit), except that the Borrower may not assign or otherwise transfer
any of its rights or obligations hereunder without the prior written consent of
each Lender (and any attempted assignment or transfer by the Borrower without
such consent shall be null and void). Nothing in this Agreement, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby (including any
Affiliate of the Issuing Bank that issues any Letter of Credit) and, to the
extent expressly contemplated hereby, the Related Parties of each of the
Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable
right, remedy or claim under or by reason of this Agreement.

         (b) Any Lender may assign to one or more assignees all or a portion of
its rights and obligations under this Agreement (including all or a portion of
its Revolving Commitment and the Loans at the time owing to it) by executing,
and causing the assignee thereof to execute, an Assignment and Acceptance;
provided that (i) except in the case of an assignment to a Lender or a Lender
Affiliate, each of the Borrower and the Administrative Agent (and, in the case
of an assignment of all or a portion of a Revolving Commitment or any Revolving
Lender's obligations in respect of its LC Exposure, the Issuing Bank) must give
their prior written consent to such assignment (which consent shall not be
unreasonably withheld or delayed), (ii) except in the case of an assignment to a
Lender or a Lender Affiliate or an assignment of the entire remaining amount of
an assigning Revolving Lender's Revolving Commitment, the aggregate amount of
the Revolving Commitments assigned to an assignee, and the aggregate amount of
the Revolving Commitments retained by the assignor after giving effect to such
assignment, shall not be less than $10,000,000 (provided, that, if the Revolving
Commitments have expired or terminated, such limits shall apply to the amount of
the Revolving Credit Exposure assigned and retained), (iii) except in the case
of an assignment to a Lender or a Lender Affiliate or an assignment of the
entire remaining amount of an assigning Revolving Lender's Revolving Commitment,
the aggregate amount of the Revolving Commitments of the assigning Revolving
Lender subject to each such assignment (determined as of the date the Assignment
and Acceptance with respect to such assignment is delivered to the
Administrative Agent) shall be in increments of $1,000,000 and not be less than
$5,000,000, unless each of the Borrower and the Administrative Agent otherwise
consent, (iv) except in the case of an assignment to a Lender or a Lender
Affiliate, or an assignment of the entire interest of a Term Lender in the Term
Loans held by it, the aggregate amount of the Term Loans of the assigning Term
Lender subject to each such assignment (determined as of the date the Assignment
and

                                                                              75
<PAGE>
Acceptance with respect to such assignment is delivered to the Administrative
Agent) shall be in increments of $1,000,000 and not less than $1,000,000, unless
each of the Borrower and the Administrative Agent otherwise consent, (v) each
partial assignment shall be made as an assignment of a proportionate part of all
the assigning Lender's rights and obligations under this Agreement, except that
this clause (v) shall not apply to rights in respect of outstanding Competitive
Loans, (vi) the parties to each assignment shall execute and deliver to the
Administrative Agent an Assignment and Acceptance, together with a processing
and recordation fee of $3,500, except in the case of an assignment to a Lender
Affiliate, in which case no processing and recordation fee shall be payable, and
(vii) the assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire; and provided further that
any consent of the Borrower otherwise required under this paragraph shall not be
required if an Event of Default has occurred and is continuing. Subject to
acceptance and recording thereof pursuant to paragraph (d) of this Section
10.04, from and after the effective date specified in each Assignment and
Acceptance the assignee thereunder shall be a party hereto and to the other Loan
Documents and, to the extent of the interest assigned by such Assignment and
Acceptance, have the rights and obligations of a Lender under this Agreement,
and the assigning Lender thereunder shall, to the extent of the interest
assigned by such Assignment and Acceptance, be released from its obligations
under this Agreement (and, in the case of an Assignment and Acceptance covering
all of the assigning Lender's rights and obligations under this Agreement and
the other Loan Documents, such Lender shall cease to be a party hereto but shall
continue to be entitled to the benefits of Sections 2.15, 2.16, 2.17, 2.19 and
10.03). Any assignment or transfer by a Lender of rights or obligations under
this Agreement that does not comply with this paragraph shall be treated for
purposes of this Agreement as a sale by such Lender of a participation in such
rights and obligations in accordance with paragraph (e) of this Section
10.04(b).

         (c) The Administrative Agent, acting for this purpose as an agent of
the Borrower, shall maintain at one of its offices in Houston, Texas or Dallas,
Texas a copy of each Assignment and Acceptance delivered to it and a register
for the recordation of the names and addresses of the Lenders, and the
Commitment of, and principal amount of the Loans and LC Disbursements owing to,
each Lender pursuant to the terms hereof from time to time (the "Register"). The
entries in the Register shall be conclusive, and the Borrower, the
Administrative Agent, the Issuing Bank and the Lenders may treat each Person
whose name is recorded in the Register pursuant to the terms hereof as a Lender
hereunder for all purposes of this Agreement and the other Loan Documents,
notwithstanding notice to the contrary. The Register shall be available for
inspection by the Borrower, the Issuing Bank and any Lender, at any reasonable
time and from time to time upon reasonable prior notice.

         (d) Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee, the assignee's completed
Administrative Questionnaire (unless the assignee shall already be a Lender
hereunder), the processing and recordation fee referred to in paragraph (b) of
this Section 10.04 and any written consent to such assignment required by
paragraph (b) of this Section 10.04, the Administrative Agent shall accept such
Assignment and Acceptance and record the information contained therein in the
Register. No assignment shall be effective for purposes of this Agreement unless
it has been recorded in the Register as provided in this paragraph.

                                                                              76
<PAGE>
         (e) Any Lender may, without the consent of the Borrower, the
Administrative Agent or the Issuing Bank, sell participations to one or more
banks or other entities (a "Participant") in all or a portion of such Lender's
rights and obligations under this Agreement (including all or a portion of its
Revolving Commitment and the Loans owing to it); provided that (i) such Lender's
obligations under this Agreement shall remain unchanged, (ii) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations and (iii) the Borrower, the Administrative Agent, the Issuing
Bank and the other Lenders shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under this
Agreement. Any agreement or instrument pursuant to which a Lender sells such a
participation shall provide that such Lender shall retain the sole right to
enforce the Loan Documents and to approve any amendment, modification or waiver
of any provision of the Loan Documents; provided that such agreement or
instrument may provide that such Lender will not, without the consent of the
Participant, agree to any amendment, modification or waiver described in the
first proviso to Section 10.02(b) that affects such Participant. Subject to
paragraph (f) of this Section 10.04, the Borrower agrees that each Participant
shall be entitled to the benefits of Sections 2.15, 2.16 and 2.17 to the same
extent as if it were a Lender and had acquired its interest by assignment
pursuant to paragraph (b) of this Section 10.04. To the extent permitted by law,
each Participant also shall be entitled to the benefits of Section 10.08 as
though it were a Lender, provided such Participant agrees to be subject to
Section 2.18(c) as though it were a Lender.

         (f) A Participant shall not be entitled to receive any greater payment
under Section 2.15 or 2.17 than the applicable Lender would have been entitled
to receive with respect to the participation sold to such Participant, unless
the sale of the participation to such Participant is made with the Borrower's
prior written consent. A Participant that would be a Foreign Lender if it were a
Lender shall not be entitled to the benefits of Section 2.17 unless the Borrower
is notified of the participation sold to such Participant and such Participant
agrees, for the benefit of the Borrower, to comply with Section 2.17(e) as
though it were a Lender.

         (g) Any Lender may at any time pledge or assign a security interest in
all or any portion of its rights under this Agreement to secure obligations of
such Lender, including any pledge or assignment to secure obligations to a
Federal Reserve Bank, and this Section shall not apply to any such pledge or
assignment of a security interest; provided that no such pledge or assignment of
a security interest shall release a Lender from any of its obligations hereunder
or substitute any such pledgee or assignee for such Lender as a party hereto.

     SECTION 10.05 Survival. All covenants, agreements, representations and
warranties made by the Borrower and the Material Subsidiaries in the Loan
Documents and in the certificates or other instruments delivered in connection
with or pursuant to this Agreement or any other Loan Document shall be
considered to have been relied upon by the other parties hereto and shall
survive the execution and delivery of this Agreement and the other Loan
Documents and the making of any Loans and issuance of any Letters of Credit,
regardless of any investigation made by any such other party or on its behalf
and notwithstanding that any Agent, the Issuing Bank, the Arranger or any Lender
may have had notice or knowledge of any Default or incorrect representation or
warranty at the time any credit is extended hereunder, and shall continue in
full force and effect as long as the principal of or any accrued interest on any
Loan or any fee or any other amount payable under this Agreement is outstanding
and unpaid or any

                                                                              77
<PAGE>
Letter of Credit is outstanding and so long as the Commitments have not expired
or terminated. The provisions of Sections 2.15, 2.16, 2.17, 2.19 and 10.03 and
Article IX shall survive and remain in full force and effect regardless of the
consummation of the transactions contemplated hereby, the repayment of the
Loans, the expiration or termination of the Letters of Credit and the
Commitments or the termination of this Agreement or any provision hereof.

     SECTION 10.06 Counterparts; Integration; Effectiveness. This Agreement may
be executed in counterparts (and by different parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement and any
separate letter agreements with respect to fees payable to the Agents constitute
the entire contract among the parties relating to the subject matter hereof and
supersede any and all previous agreements and understandings, oral or written,
relating to the subject matter hereof. Except as provided in Article IV, this
Agreement shall become effective when it shall have been executed by the
Administrative Agent and when the Administrative Agent shall have received
counterparts hereof which, when taken together, bear the signatures of each of
the other parties hereto, and thereafter shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns.
Delivery of an executed counterpart of a signature page of this Agreement by
telecopy shall be effective as delivery of a manually executed counterpart of
this Agreement.

     SECTION 10.07 Severability. Any provision of this Agreement held to be
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

     SECTION 10.08 Right of Setoff. If an Event of Default shall have occurred
and be continuing, each Lender and each of its Affiliates is hereby authorized
at any time and from time to time, to the fullest extent permitted by law, to
set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other obligations at any time owing
by such Lender or Affiliate to or for the credit or the account of the Borrower
against any of and all the obligations of the Borrower now or hereafter existing
under this Agreement held by such Lender, irrespective of whether or not such
Lender shall have made any demand under this Agreement and although such
obligations may be unmatured. The rights of each Lender under this Section are
in addition to other rights and remedies (including other rights of setoff)
which such Lender may have.

     SECTION 10.09 SECTION 10.09 Governing Law; Jurisdiction; Consent to Service
of Process.

         (a) This Agreement and the other Loan Documents shall be construed in
accordance with and governed by the law of the State of Texas.

         (b) The Borrower hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of the Courts of the
State of Texas and of the United States District Court for the Northern District
of Texas, and any appellate court from any thereof, in any action or proceeding
arising out of or relating to this Agreement, or for

                                                                              78
<PAGE>
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in such Texas State or, to
the extent permitted by law, in such Federal court. Each of the parties hereto
agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Agreement or any other Loan
Document shall affect any right that the Administrative Agent, the Issuing Bank
or any Lender may otherwise have to bring any action or proceeding relating to
this Agreement against the Borrower or its properties in the courts of any
jurisdiction.

         (c) The Borrower hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement or any other Loan Document in any
court referred to in paragraph (b) of this Section 10.09. Each of the parties
hereto hereby irrevocably waives, to the fullest extent permitted by law, the
defense of an inconvenient forum to the maintenance of such action or proceeding
in any such court.

         (d) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 10.01. Nothing in this
Agreement or any other Loan Document will affect the right of any party to this
Agreement to serve process in any other manner permitted by law.

     SECTION 10.10 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING
TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED
HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO
(A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE
EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES
THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS
AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
SECTION 9.10.

     SECTION 10.11 Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement.

     SECTION 10.12 Confidentiality. Each of the Agents, the Issuing Bank and the
Lenders agrees to maintain the confidentiality of the Information (as defined
below), except that Information may be disclosed (a) to its and its Affiliates'
directors, officers, employees and agents, including accountants, legal counsel
and other advisors (it being understood that the Persons to whom such disclosure
is made will be informed of the confidential nature of such

                                                                              79
<PAGE>
Information and instructed to keep such Information confidential), (b) to the
extent requested by any regulatory authority, (c) to the extent required by
applicable laws or regulations or by any subpoena or similar legal process, (d)
to any other party to this Agreement, (e) in connection with the exercise of any
remedies hereunder or any suit, action or proceeding relating to this Agreement
or any other Loan Document or the enforcement of rights hereunder, (f) subject
to an agreement containing provisions substantially the same as those of this
Section 10.12, to any assignee of or Participant in, or any prospective assignee
of or Participant in, any of its rights or obligations under this Agreement, (g)
with the consent of the Borrower or (h) to the extent such Information (i)
becomes publicly available other than as a result of a breach of this Section
10.12 or (ii) becomes available to the Administrative Agent, the Issuing Bank or
any Lender on a nonconfidential basis from a source other than the Borrower. For
the purposes of this Section 10.12, "Information" means all information received
from the Borrower relating to the Borrower or its business, other than any such
information that is available to the Administrative Agent, the Issuing Bank or
any Lender on a non-confidential basis prior to disclosure by the Borrower;
provided that, in the case of information received from the Borrower after the
date hereof, such information is clearly identified at the time of delivery as
confidential. Any Person required to maintain the confidentiality of Information
as provided in this Section shall be considered to have complied with its
obligation to do so if such Person has exercised the same degree of care to
maintain the confidentiality of such Information as such Person would accord to
its own confidential information.

     SECTION 10.13 Interest Rate Limitation. It is the intention of the parties
hereto to conform strictly to applicable interest, usury and criminal laws and,
anything herein to the contrary notwithstanding, the obligations of the Borrower
or any Material Subsidiary to a Lender, the Issuing Bank or any Agent under this
Agreement or any other Loan Document shall be subject to the limitation that
payments of interest shall not be required to the extent that receipt thereof
would be contrary to provisions of law applicable to such Lender, the Issuing
Bank or such Agent limiting rates of interest which may be charged or collected
by such Lender, the Issuing Bank or such Agent. Accordingly, if the transactions
contemplated hereby or thereby would be illegal, unenforceable, usurious or
criminal under laws applicable to a Lender, the Issuing Bank or any Agent
(including the laws of any jurisdiction whose laws may be mandatorily applicable
to such Lender or the Administrative Agent notwithstanding anything to the
contrary in this Agreement or any other Loan Document) then, in that event,
notwithstanding anything to the contrary in this Agreement or any other Loan
Document, it is agreed as follows:

         (i) the provisions of this Section 10.13 shall govern and control;

         (ii) the aggregate of all consideration which constitutes interest
     under applicable law that is contracted for, taken, reserved, charged or
     received under this Agreement, or under any of the other aforesaid
     agreements or otherwise in connection with this Agreement or any other Loan
     Document by such Lender, the Issuing Bank or such Agent shall under no
     circumstances exceed the maximum amount of interest allowed by applicable
     law (such maximum lawful interest rate if any, with respect to such Lender,
     the Issuing Bank and the Agents herein called the "Highest Lawful Rate"),
     and any excess shall be canceled automatically and if theretofore paid
     shall be credited to the

                                                                              80
<PAGE>
     Borrower by such Lender, the Issuing Bank or such Agent (or, if such
     consideration shall have been paid in full, such excess refunded to the
     Borrower);

         (iii) all sums paid, or agreed to be paid, to such Lender, the Issuing
     Bank or such Agent for the use, forbearance and detention of the
     indebtedness of the Borrower to such Lender, the Issuing Bank or such Agent
     hereunder or under any Loan Document shall, to the extent permitted by laws
     applicable to such Lender, the Issuing Bank or such Agent, as the case may
     be, be amortized, prorated, allocated and spread throughout the full term
     of such indebtedness until payment in full so that the actual rate of
     interest is uniform throughout the full term thereof;

         (iv) if at any time the interest provided pursuant to this Section
     10.13 or any other clause of this Agreement or any other Loan Document,
     together with any other fees or compensation payable pursuant to this
     Agreement or any other Loan Document and deemed interest under laws
     applicable to such Lender, the Issuing Bank or such Agent, exceeds that
     amount which would have accrued at the Highest Lawful Rate, the amount of
     interest and any such fees or compensation to accrue to such Lender, the
     Issuing Bank or such Agent pursuant to this Agreement or such other Loan
     Document shall be limited, notwithstanding anything to the contrary in this
     Agreement or any other Loan Document, to that amount which would have
     accrued at the Highest Lawful Rate, but any subsequent reductions, as
     applicable, shall not reduce the interest to accrue to such Lender, the
     Issuing Bank or such Agent pursuant to this Agreement or such other Loan
     Document below the Highest Lawful Rate until the total amount of interest
     accrued pursuant to this Agreement or such other Loan Document, as the case
     may be, and such fees or compensation deemed to be interest equals the
     amount of interest which would have accrued to such Lender, the Issuing
     Bank or such Agent if a varying rate per annum equal to the interest
     provided pursuant to any other relevant Section hereof (other than this
     Section 10.13) or thereof as applicable, had at all times been in effect,
     plus the amount of fees which would have been received but for the effect
     of this Section 10.13; and

         (v) with the intent that the rate of interest herein shall at all times
     be lawful, if the receipt of any funds owing hereunder or under any other
     agreement related hereto (including any of the other Loan Documents) by
     such Lender, the Issuing Bank or such Agent would cause such Lender, the
     Issuing Bank or such Agent to charge the Borrower a criminal rate of
     interest, the Lenders, the Issuing Bank and the Agents agree that they will
     not require the payment or receipt thereof or a portion thereof which would
     cause a criminal rate of interest to be charged by such Lender, the Issuing
     Bank or such Agent, as applicable, and if received such affected Lender,
     the Issuing Bank or such Agent will return such funds to the Borrower so
     that the rate of interest paid by the Borrower shall not exceed a criminal
     rate of interest from the date this Agreement was entered into.

     SECTION 10.14 Arranger; Syndication Agents. None of the Arranger or the
Syndication Agents shall have any right, power, obligation, liability,
responsibility or duty under this Agreement or any other Loan Document other
than, except in the case of the Arranger, those applicable to all Lenders as
such. Without limiting the foregoing, none of the Arranger or the Syndication
Agents shall have or be deemed to have any fiduciary relationship with any
Lender

                                                                              81
<PAGE>
or the Borrower or any of its Subsidiaries. The Borrower and each Lender
acknowledge that it has not relied, and will not rely, on any of the Arranger or
the Syndication Agents in deciding to enter into this Agreement or in taking any
action hereunder or under the Loan Documents.

     SECTION 10.15 NO ORAL AGREEMENTS. THIS WRITTEN AGREEMENT AND THE OTHER LOAN
DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN OR AMONG THE PARTIES WITH
RESPECT TO THE SUBJECT MATTER HEREOF AND MAY NOT BE CONTRADICTED BY EVIDENCE OF
PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE
NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed by their respective authorized officers as of the day and year
first above written.

                               GUARANTY PROVISIONS

     Section 2.1 GUARANTY. The Guarantor hereby absolutely, unconditionally and
irrevocably

         (a)   guarantees the full and punctual payment when due, whether at
stated maturity, by required prepayment, declaration, acceleration, demand or
otherwise, of all Lender Indebtedness of the Borrower and each other Loan Party
now or hereafter existing under the Credit Agreement and each other Loan
Document to which the Borrower or such other Loan Party is or may become a
party, whether for principal, interest, fees, expenses or otherwise (including
all such amounts which would become due but for the operation of the automatic
stay under Section 362(4) of the United States Bankruptcy Code, 11 U.S.C.
ss.362(4), and the operation of Sections 502(b) and 506(b) of the United States
Bankruptcy Code, 11 U.S.C. ss.502(b) and ss.506(b)), and

                                                                             B-2

<PAGE>

         (b)   indemnifies each Lender Party for any and all costs and expenses
(including reasonable attorney's fees and expenses) incurred by such Lender or
such holder, as the case may be, in enforcing any rights under this Guaranty;

provided, however, that the Guarantor shall be liable under this Guaranty for
the maximum amount of such liability that can be hereby incurred without
rendering this Guaranty, as it relates to the Guarantor, voidable under
applicable law relating to fraudulent conveyance or fraudulent transfer, and not
for any greater amount. This Guaranty constitutes a guaranty of payment when due
and not of collection, and the Guarantor specifically agrees that it shall not
be necessary or required that any Lender Party exercise any right, assert any
claim or demand, or enforce any remedy whatsoever against the Borrower or any
other Loan Party (or any other Person) before or as a condition to the
obligations of the Guarantor hereunder.

     Section 2.2 ACCELERATION OF GUARANTY. The Guarantor agrees that, in the
event that the Lender Indebtedness has been accelerated pursuant to Article VIII
of the Credit Agreement, the Guarantor will pay to the Administrative Agent for
itself and as agent for the Lender Parties forthwith the full amount of all such
Lender Indebtedness.

     Section 2.3 GUARANTY ABSOLUTE, ETC. This Guaranty shall in all respects be
a continuing, absolute, unconditional and irrevocable guaranty of payment, and
shall remain in full force and effect until all Lender Indebtedness of the
Borrower and each other Loan Party has been paid in full, all obligations of the
Guarantor hereunder shall have been paid in full and all Commitments shall have
terminated and all Letters of Credit shall have terminated or expired. The
Guarantor guarantees that the Lender Indebtedness of the Borrower and each other
Loan Party will be paid strictly in accordance with the terms of the Credit
Agreement and each other Loan Document under which they arise, regardless of any
law, regulation or order now or hereafter in effect in any jurisdiction
affecting any of such terms or the rights of any Lender Party or any holder of
any note with respect thereto. The liability of the Guarantor under this
Guaranty shall be absolute, unconditional and irrevocable irrespective of:

         (a)   any lack of validity, legality or enforceability of the Credit
Agreement or any other Loan Document;

         (b)   the failure of any Lender Party

               (1)  to assert any claim or demand or to enforce any right or
     remedy against the Borrower, any other Loan Party or any other Person
     (including any other guarantor) under the provisions of the Credit
     Agreement, any other Loan Document, or otherwise, or

               (2)  to exercise any right or remedy against any other guarantor
     of any Lender Indebtedness of the Borrower or any other Loan Party;

         (c)   any change in the time, manner or place of payment of, or in any
other term of, all or any of the Lender Indebtedness of the Borrower or any
other Loan Party, or any

                                                                             B-3

<PAGE>

other extension, compromise, or renewal of any Lender Indebtedness of the
Borrower or any other Loan Party;

         (d)   any reduction, limitation, impairment or termination of any
Lender Indebtedness of the Borrower or any other Loan Party for any reason
(other than indefeasible payment in full in cash of the Lender Indebtedness),
including any claim of waiver, release, surrender, alteration or compromise, and
shall not be subject to (and the Guarantor hereby waives any right to or claim
of) any defense or setoff, counterclaim, recoupment or termination whatsoever by
reason of the invalidity, illegality, non-genuineness, irregularity, compromise,
unenforceability of, or any other event or occurrence affecting, any Lender
Indebtedness of the Borrower, any other Loan Party or otherwise;

         (e)   any amendment to, rescission, waiver, or other modification of,
or any consent to departure from, any of the terms of the Credit Agreement or
any other Loan Document;

         (f)   any addition, exchange, release, surrender or non-perfection of
any collateral, or any amendment to or waiver or release or addition of, or
consent to departure from, any other guaranty, held by any Lender Party securing
any of the Lender Indebtedness of the Borrower or any other Loan Party; or

         (g)   any other circumstance (other than indefeasible payment in full
in cash of the Lender Indebtedness) which might otherwise constitute a defense
available to, or a legal or equitable discharge of, the Borrower, any other Loan
Party, any surety, or any guarantor.

     Section 2.4 REINSTATEMENT, ETC. The Guarantor agrees that this Guaranty
shall continue to be effective or be reinstated, as the case may be, if at any
time any payment (in whole or in part) of any of the Lender Indebtedness is
rescinded or must otherwise be restored by any Lender Party, upon the
insolvency, bankruptcy or reorganization of the Borrower, any other Loan Party
or otherwise, all as though such payment had not been made.

     Section 2.5 WAIVER, ETC. The Guarantor hereby waives promptness, diligence,
notice of acceptance and any other notice with respect to any of the Lender
Indebtedness of the Borrower or any other Loan Party and this Guaranty and any
requirement that the Administrative Agent or any other Lender Party protect,
secure, perfect or insure any Lien, or any property subject thereto, or exhaust
any right or take any action against the Borrower, any other Loan Party or any
other Person (including any other guarantor) or any collateral securing the
Lender Indebtedness of the Borrower or any other Loan Party, as the case may be.

     Section 2.6 WAIVER OF SUBROGATION. Until the indefeasible payment in full
in cash of all Lender Indebtedness and the termination or expiration of all
Commitments and Letters of Credit, the Guarantor hereby irrevocably waives any
claim or other rights which it may now or hereafter acquire against the Borrower
or any other Loan Party that arise from the existence, payment, performance or
enforcement of the Guarantor's obligations under this Guaranty or any other Loan
Document, including any right of subrogation, reimbursement, exoneration, or
indemnification, any right to participate in any claim or remedy of the Lender
Parties against the

                                                                             B-4

<PAGE>

Borrower or any other Loan Party or any collateral which the Administrative
Agent now has or hereafter acquires, whether or not such claim, remedy or right
arises in equity, or under contract, statute or common law, including the right
to take or receive from the Borrower or any other Loan Party, directly or
indirectly, in cash or other property or by set-off or in any manner, payment or
security on account of such claim or other rights. If any amount shall be paid
to the Guarantor in violation of the preceding sentence, such amount shall be
deemed to have been paid to the Guarantor for the benefit of, and held in trust
for, the Lender Parties, and shall forthwith be paid to the Administrative Agent
for the benefit of the Lender Parties to be credited and applied to the Lender
Indebtedness, whether matured or unmatured. The Guarantor acknowledges that it
will receive direct and indirect benefits from the financing arrangements
contemplated by the Credit Agreement and that the waiver set forth in this
Section is knowingly made in contemplation of such benefits.

                                    ARTICLE 3
                         REPRESENTATIONS AND WARRANTIES

     Section 3.1 REPRESENTATIONS AND WARRANTIES. The Guarantor hereby
represents and warrants unto each Lender Party as set forth in this Article.

     Section 3.2 ORGANIZATION; POWERS. The Guarantor is duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
organization, has all requisite power and authority to carry on its business as
now conducted and, except where the failure to do so, individually or in the
aggregate, could not reasonably be expected to result in a Material Adverse
Effect, is qualified to do business in, and is in good standing in, every
jurisdiction where such qualification is required.

     Section 3.3 AUTHORIZATION; ENFORCEABILITY. The execution, delivery and
performance by the Guarantor of this Guaranty and each other Loan Document
executed or to be executed by it are within the Guarantor's corporate,
partnership or limited liability company powers (as applicable), and have been
duly authorized by all necessary corporate, partnership or limited liability
company action (as applicable), and if required and applicable, stockholder
action. This Guaranty has been duly executed and delivered by the Guarantor and
constitutes, and each other Loan Document executed or to be executed by the
Guarantor, when executed and delivered by the Guarantor, will constitute, a
legal, valid and binding obligation of the Guarantor, enforceable in accordance
with their respective terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium or other laws affecting creditors' rights generally
and subject to general principles of equity, regardless of whether considered in
a proceeding in equity or at law.

     Section 3.4 APPROVALS; NO CONFLICTS. The execution, delivery and
performance by the Guarantor of this Guaranty and each other Loan Document
executed or to be executed by it, (a) do not require any approval of any
Governmental Authority or other third party approvals, except such as have been
obtained or made and are in full force and effect and except filings necessary
to perfect Liens created in connection with this Guaranty, (b) will not violate
any applicable Governmental Rule or the articles of organization, formation or
incorporation (or comparable document), bylaws, operating agreement, partnership
agreement, limited liability company agreement or similar documents (as
applicable) of the Guarantor or any

                                                                             B-5

<PAGE>

order of any Governmental Authority, (c) will not violate or result in a default
under any indenture, agreement, or other instrument binding upon the Guarantor
or its assets, or give rise to a right thereunder to require any payment to be
made by the Guarantor and (d) will not result in the creation or imposition of
any Lien on any asset of the Guarantor except Liens created under the Loan
Documents.

     Section 3.5 BENEFIT TO THE GUARANTOR. The Guarantor is a wholly-owned
subsidiary of the Borrower; and the Guarantor's guaranty pursuant to this
Guaranty reasonably may be expected to benefit, directly or indirectly, the
Guarantor; and the Guarantor has determined that this Guaranty is necessary and
convenient to the conduct, promotion and attainment of the business of the
Guarantor and the Borrower.

     Section 3.6 LITIGATION MATTERS. Except for Disclosed Matters, there are no
actions, suits or proceedings by or before any arbitrator or Governmental
Authority pending against or, to the knowledge of the Guarantor, threatened
against or affecting the Guarantor or any of its Subsidiaries or any of their
respective properties, businesses, assets or revenues, (i) as to which there is
a reasonable possibility of an adverse determination and that, if adversely
determined, could reasonably be expected, individually or in the aggregate, to
result in a Material Adverse Effect (other than the Disclosed Matters) or (ii)
that question the validity or enforceability of any Loan Documents or seek to
enjoin or prevent the Transactions. Since the date of this Guaranty, there has
been no change in the status of the Disclosed Matters that, individually or in
the aggregate, has resulted in, or materially increased the likelihood of, a
Material Adverse Effect.

     Section 3.7 SOLVENCY. Immediately after entering into this Guaranty, the
Guarantor will be Solvent. As used herein, the term "Solvent" means, with
respect to the Guarantor, a condition under which (a) the fair market value of
the Guarantor's assets is, on the date of determination greater than the total
amount of the Guarantor's liabilities (including contingent and unliquidated
liabilities) at such time; and (b) the Guarantor is able to pay all of its
liabilities as such liabilities mature. For purposes of this definition (i) the
amount of the Guarantor's contingent or unliquidated liabilities at any time
shall be the amount which, in light of all the facts and circumstances then
existing, represents the amount which can reasonably be expected to become an
actual or matured liability, (ii) the "fair saleable value" of an asset shall be
the amount which may be realized within a reasonable time either through
collection or sale of such asset at its regular market value, and (iii) the
"regular market value" of an asset shall be the amount which a capable and
diligent business person could obtain for such asset from an interested buyer
who is willing to purchase such asset under ordinary selling conditions.

     Section 3.8 CREDIT AGREEMENT REPRESENTATIONS. All representations and
warranties made by the Borrower with respect to the Guarantor set forth in
Article III of the Credit Agreement are true and correct in all respects as of
the date hereof.

                                    ARTICLE 4
                                 COVENANTS, ETC.

     Section 4.1 COVENANTS. Until the payment in full in cash of all Lender
Indebtedness and the termination or expiration of all Commitments and Letters of
Credit, the Guarantor

                                                                             B-6

fulfill each of the covenants, agreements and obligations contained in the

the Credit Agreement, pertaining or otherwise applicable to the Guarantor in its
capacity as a Loan Party and a Subsidiary. The Guarantor hereby irrevocably and
unconditionally agrees to be bound by such covenants, agreements and obligations
applicable to it in such capacities as if the Guarantor were a party to the
Credit Agreement and such covenants, agreements, and obligations applicable to
it in such capacities are hereby reaffirmed by the Guarantor.

                                    ARTICLE 5
                            MISCELLANEOUS PROVISIONS

herein) be construed, administered and applied in accordance with the terms and
provisions thereof.

This Guaranty shall be binding upon the Guarantor and its successors,
transferees and assigns and shall inure to the benefit of and be enforceable by
the Administrative Agent, each other Lender Party and their respective
successors, transferees and assigns permitted by Section 10.04 of the Credit
Agreement.

     Section 5.3 AMENDMENTS, ETC. No amendment to or waiver of any provision
of this Guaranty, nor consent to any departure by the Guarantor herefrom, shall
in any event be effective unless the same shall be in writing and signed by the
Administrative Agent in accordance with Section 10.02(b) of the Credit
Agreement, and then such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given.

     Section 5.4 ADDRESSES FOR NOTICES TO THE GUARANTOR. All notices and other
communications hereunder to the Guarantor shall be in writing (including
telecopy communication) and mailed or telecopied or delivered to it, addressed
to it at the address set forth below its signature hereto, or at such other
address as shall be designated by the Guarantor in a written notice to the

         As of the date of this Agreement, each Debtor represents and warrants
to the Agent and the Creditors that:

     Section 3.01 Location of Inventory; Third Parties in Possession. All of
its inventory is located at the places specified in Schedule 3.01 for such
Debtor. Schedule 3.01 correctly identifies the landlords or mortgagees, if any,
of each of its locations identified in Schedule 3.01. Except for the Persons
identified on Schedule 3.01 who hold Collateral in the capacity designated on
Schedule 3.01, no Person other than the Debtors and the Agent has possession of
any of the Collateral. None of its Collateral has been located in any location
within the past four months other than as set forth on Schedule 3.01 for such
Debtor.

     Section 3.02 Office Locations; Fictitious Names; Tax I.D. Number. Its
principal place of business, chief executive office and jurisdiction of
organization are located at the place or places identified for it on Schedule
3.01. Within the last four months it has not had any other chief place of
business, chief executive office, or jurisdiction of organization except as
disclosed on Schedule 3.01.

                                                                             H-2

<PAGE>

Schedule 3.01 also sets forth all other places where it keeps its books and
records and all other locations where it has a place of business. It does not do
business and has not done business during the past five years under any
trade-name or fictitious business name except as disclosed on Schedule 3.02.
Schedule 3.02 sets forth an accurate list of all names of all of its predecessor
companies including the names of any entities it acquired (by stock purchase,
asset purchase, merger or otherwise), the chief place of business, chief
executive office and jurisdiction of organization of each such predecessor
company and each jurisdiction in which any collateral purchased from such
companies was located at the time of purchase. For purposes of the foregoing, a
"predecessor company" shall mean, with respect to a Debtor, any Person whose
assets or equity interests are acquired by such Debtor or who was merged with or
into such Debtor within the last four months prior to the date hereof. Its
United States Federal Income Tax I.D. Number and organizational identification
number are set forth on Schedule 3.02.

     Section 3.03 Delivery of Collateral. Each Debtor has delivered to the Agent
all Collateral the possession of which is necessary to perfect the security
interest of the Agent therein.

     Section 3.04 Organization; Powers. Each Debtor is duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
organization, has all requisite power and authority to carry on its business as
now conducted and, except where the failure to do so, individually or in the
aggregate, could not reasonably be expected to result in a material adverse
effect on such Debtor or its Collateral, is qualified to do business in, and is
in good standing in, every jurisdiction where such qualification is required.

     Section 3.05 Authorization; Enforceability. This Agreement and the other
Transaction Documents to be entered into by each Debtor are within their
respective corporate powers and have been duly authorized by all necessary
corporate and, if required, stockholder action. This Agreement has been duly
executed and delivered by each Debtor and constitutes, and each other
Transaction Document to which any Debtor is to be a party, when executed and
delivered, will constitute, a legal, valid and binding obligation of such Debtor
(as the case may be), enforceable in accordance with its terms, subject to
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws affecting creditors' rights generally and subject to general principles of
equity, regardless of whether considered in a proceeding in equity or at law.

     Section 3.06 Governmental Approvals; No Conflicts. The execution,
performance and delivery of the Transaction Documents by each Debtor (a) do not
require any consent or approval of, registration or filing with (other than the
inclusion of this Agreement as an exhibit to routine filings under the
Securities Exchange Act of 1934 and filings required to perfect the security
interests herein granted required by the Uniform Commercial Code), or any other
action by, any governmental authority, (b) will not violate any applicable law
or regulation or the charter, by-laws or other organizational documents of any
Debtor or any order of any governmental authority, (c) will not violate in any
material respect or result in a material default under any indenture, material
agreement or other instrument binding upon any Debtor or its assets, or give
rise to a right thereunder to require any payment to be made by any Debtor, and
(d) will not result in the creation or imposition of any security interest or
lien on any asset of any Debtor except as specifically contemplated hereby.

                                   ARTICLE IV
                                    COVENANTS

         Each Debtor covenants and agrees with the Agent that until the
Obligations are paid an performed in full and the Intercreditor Agreement
terminates:

                                                                             H-3

<PAGE>

     Section 4.01 Accounts. It shall, in accordance with its customary business
practices, endeavor to collect or cause to be collected from each account debtor
under its accounts, as and when due, any and all amounts owing under such
accounts. Without the prior written consent of the Agent, it shall not, except
in the ordinary course of business when no Event of Default exists, (a) grant
any extension of time for any payment with respect to any of its accounts beyond
120 days after such payment's due date, (b) compromise, compound, or settle any
of its accounts for less than the full amount thereof, (c) release, in whole or
in part, any Person liable for payment of any of its accounts, (d) allow any
credit or discount for payment with respect to any of its accounts other than
trade or other customary discounts granted in the ordinary course of business,
or (e) release any lien, security interest or guaranty securing any of its
accounts unless the account has been paid.

     Section 4.02 Further Assurances; Exceptions to Perfection. At any time and
from time to time, upon the request of the Agent, and at its sole expense, it
shall, promptly execute and deliver all such further agreements, instruments and
documentation and take such further action as the Agent may reasonably deem
necessary or appropriate to preserve and perfect its security interest in the
Collateral and carry out the provisions and purposes of this Agreement or to
enable the Agent to exercise and enforce its rights and remedies hereunder with
respect to any of the Collateral. Without limiting the generality of the
foregoing, it shall upon reasonable request by the Agent, (i) execute and
deliver to the Agent such financing statements as the Agent may from time to
time require (each Debtor also hereby authorizes the Agent to file such
financing statements without Debtor's signature naming it as debtor, the Agent
as secured party and describing the Collateral, in each case as the Agent may
deem appropriate); (ii) take such action as the Agent may request to permit the
Agent to have control over any deposit account; (iii) deliver to the Agent all
Collateral the possession of which is necessary to perfect the security interest
therein, duly endorsed and/or accompanied by duly executed instruments of
transfer or assignment, all in form and substance satisfactory to the Agent; and
(iv) execute and deliver to the Agent such other agreements, instruments and
documentation as the Agent may reasonably require to perfect and maintain the
validity, effectiveness and priority of the security interests intended to be
created by this Agreement; except that, prior to the occurrence of a Potential
Default:

         (a)   the Debtors may retain and utilize in the ordinary course of
business proceeds of accounts;

         (b)   the Debtors may retain and utilize in the ordinary course of
business any letters of credit received in the ordinary course of business;

         (c)   the Debtors may retain any documents received and further
negotiated in the ordinary course of business; and

         (d)   no Debtor shall be required to grant the Agent control over any
deposit, commodity or security account.

If a Potential Default occurs and the Agent requests, then the Debtors shall
take such action as the Agent may reasonably request to perfect and protect the
security interests of the Agent in all of the Collateral, including without
limitation, the following actions: (A) the delivery to the Agent of all
Collateral the possession of which is necessary to perfect the security interest
of the Agent therein; (B) instructing all account debtors to make payment on
accounts and any other Collateral to a post office box or boxes or to a deposit
account under the control and in the name of the Agent and (C) any other of the
actions described in Section 4.02(i) through Section 4.02(iv) above.

                                                                             H-4

<PAGE>

     Section 4.03 Third Parties in Possession of Collateral. The Debtors shall
not permit any third Person (including any warehouseman, bailee, agent,
consignee or processor) to hold any Collateral, unless it shall: (a) notify such
third Person of the security interests created hereby; (b) instruct such Person
to hold all such Collateral for the Agent's account subject to the Agent's
instructions; and (c) subject to Section 4.02, take all other actions the Agent
reasonably deems necessary to perfect and protect its and the Debtors' interests
in such Collateral pursuant to the requirements of the Uniform Commercial Code
of the applicable jurisdiction where the warehouseman, bailee, consignee, agent,
processor or other third Person is located (including the filing of a financing
statement in the proper jurisdiction naming the applicable third Person as
debtor and it as secured party and notifying the third Person' secured lenders
of its interest in such Collateral before the third Person receives possession
of the Collateral in question).

     Section 4.04 Corporate Changes. It shall not change its name, identity,
jurisdiction of organization, or corporate structure in any manner that might
make any financing statement filed in connection with this Agreement seriously
misleading or its United States Federal Tax I.D. Number or organizational
identification number unless it shall have given the Agent thirty (30) days
prior written notice thereof and shall have taken all action reasonably deemed
necessary or desirable by the Agent to protect its security interest in the
Collateral with the perfection and priority thereof required by the Transaction
Documents and this Agreement. It shall not change its principal place of
business, chief executive office or the place where it keeps its books and
records unless it shall have given the Agent thirty (30) days prior written
notice thereof and shall have taken all action deemed necessary or desirable by
the Agent to cause its security interest in the Collateral to be perfected with
the priority required by the Transaction Documents and this Agreement.

     Section 4.05 Inventory. It shall keep its inventory at (or in transit to)
any of its locations specified on Schedule 3.01 hereto or at such other places
within the United States of America as provided in a written notice to the
Agent.

     Section 4.06 Warehouse Receipts Non-Negotiable. It agrees that if any
warehouse receipt or receipt in the nature of a warehouse receipt is issued in
respect of any portion of the Collateral, such warehouse receipt or receipt in
the nature thereof shall not be "negotiable" (as such term is used in Section
7.104 of the UCC) unless such warehouse receipt or receipt in the nature thereof
is delivered to the Agent.

                                    ARTICLE V

SUBSTITUTION, AS ITS TRUE AND LAWFUL ATTORNEY-IN-FACT WITH FULL IRREVOCABLE
POWER AND AUTHORITY IN THE NAME OF SUCH DEBTOR OR IN ITS OWN NAME, TO TAKE, WHEN
A POTENTIAL DEFAULT EXISTS, ANY AND ALL ACTIONS AND TO EXECUTE ANY AND ALL
DOCUMENTS AND INSTRUMENTS WHICH THE AGENT AT ANY TIME AND FROM TIME TO TIME

delivery of mail of the Debtor to an address designated by the Agent and to

         (d)   (1)  to direct account debtors and any other parties liable for
any payment under any of the Collateral to make payment of any and all monies
due and to become due thereunder directly to the Agent or as the Agent shall
direct (each Debtor agrees that if any proceeds of any Collateral (including
payments made in respect of accounts) shall be received by it while a Potential
Default exists, it shall promptly deliver such proceeds to the Agent with any
necessary endorsements, and until such proceeds are delivered to the Agent, such
proceeds shall be held in trust by it for the benefit of the Agent and shall not
be commingled with any other funds or property of it); (2) to receive payment of
and receipt for any and all monies, claims and other amounts due and to become
due at any time in respect of or arising out of any Collateral; (3) to sign and
endorse any invoices, freight or express bills, bills of lading, storage or
warehouse receipts, drafts against debtors, assignments, proxies, stock powers,
verifications and notices in connection with accounts and other documents
relating to the Collateral; (4) to commence and prosecute any suit, action or
proceeding at law or in equity in any court of competent jurisdiction to collect
the Collateral or any part thereof and to enforce any other right in respect of
any Collateral; (5) to defend any suit, action or proceeding brought against it
with respect to any Collateral; (6) to settle, compromise or adjust any suit,
action or proceeding described above and, in connection therewith, to give such
discharges or releases as the Agent may deem appropriate; (7) to exchange any of
the Collateral for other property upon any merger, consolidation,
reorganization, recapitalization or other readjustment of the issuer thereof
and, in connection therewith, deposit any of the Collateral with any committee,
depositary, transfer agent, registrar or other designated agency upon such terms
as the Agent may determine; (8) to add or release any guarantor, endorser,
surety or other party to any of the Collateral; (9) to renew, extend or
otherwise change the terms and conditions of any of the Collateral; (10) to
grant or issue any exclusive or nonexclusive license under or with respect to
any of the intellectual property (subject to the rights of third parties under
pre-existing licenses); (11) to endorse its name on all applications and other
documentation necessary or desirable in order for the Agent to use any
intellectual property; (12) to make, settle, compromise or adjust any claims
under or pertaining to any of the Collateral (including claims under any policy
of insurance); and (13) to sell, transfer, pledge, convey, make any agreement
with respect to or otherwise deal with any of the Collateral as fully and
completely as though the Agent were the absolute owner thereof for all purposes,
and to do, at the Agent's option and the Debtors' expense, at any time, or from
time to time, all acts and things which the Agent deems necessary to protect,
preserve, maintain, or realize upon the Collateral and the Agent's security
interest therein.

         THIS POWER OF ATTORNEY IS A POWER COUPLED WITH AN INTEREST AND SHALL BE
IRREVOCABLE UNTIL TERMINATION OF THIS AGREEMENT IN ACCORDANCE WITH SECTION 7.11.
The Agent shall be under no duty to exercise or withhold the exercise of any of
the rights, powers, privileges and options expressly or implicitly granted to
the Agent in this Agreement, and shall not be liable for any failure to do so or
any delay in doing so. Neither the Agent nor any Person

                                                                             H-6

designated by the Agent shall be liable for any act or omission or for any error
of judgment or any mistake of fact or law, except any of the same resulting from
its or their gross negligence or willful misconduct. This power of attorney is
conferred on the Agent solely to protect, preserve, maintain and realize upon
its security interest in the Collateral. The Agent shall not be responsible for
any decline in the value of the Collateral and shall not be required to take any
steps to preserve rights against prior parties or to protect, preserve or
maintain any lien or security interest given to secure the Collateral.

     Section 5.02 Assignment by the Agent. The Agent and each Creditor may at
any time assign or otherwise transfer all or any portion of their rights and
obligations under this Agreement and the other Transaction Documents (including,
without limitation, the Obligations) to any other Person, to the extent
permitted by, and upon the conditions contained in, the Transaction Documents,
and such Person shall thereupon become vested with all the benefits thereof
granted to the Agent and the Creditors, respectively, herein or otherwise.

     Section 5.03 Possession; Reasonable Care. The Agent may, from time to time,
in its sole discretion, appoint one or more agents to hold physical custody, for
the account of the Agent, of any or all of the Collateral that the Agent has a
right to possess. The Agent shall be deemed to have exercised reasonable care in
the custody and preservation of the Collateral in its possession if the
Collateral is accorded treatment substantially equal to that which the Agent
accords its own property, it being understood that the Agent shall not have any
responsibility for taking any necessary steps to preserve rights against any
parties with respect to any Collateral.

                                   ARTICLE VI
                                     DEFAULT

     Section 6.01 Rights and Remedies. If an Event of Default exists, the Agent
shall have the following rights and remedies:

         (a)   In addition to all other rights and remedies granted to the Agent
in this Agreement or in any other Transaction Document or by applicable law, the
Agent shall have all of the rights and remedies of a secured party under the UCC
(whether or not the UCC applies to the affected Collateral). Without limiting
the generality of the foregoing, the Agent may (1) without demand or notice to
any Debtor, collect, receive or take possession of the Collateral or any part
thereof and for that purpose the Agent may enter upon any premises on which the
Collateral is located and remove the Collateral therefrom or render it
inoperable, and/or (2) sell, lease or otherwise dispose of the Collateral, or
any part thereof, in one or more parcels at public or private sale or sales, at
the Agent's offices or elsewhere, for cash, on credit or for future delivery,
and upon such other terms as the Agent may deem commercially reasonable or
otherwise as may be permitted by law. The Agent shall have the right at any
public sale or sales, and, to the extent permitted by applicable law, at any
private sale or sales, to bid (which bid may be, in whole or in part, in the
form of cancellation of indebtedness) and become a purchaser of the Collateral
or any part thereof free of any right or equity of redemption on the part of any
Debtor, which right or equity of redemption is hereby expressly waived and
released by each Debtor. Upon the request of the Agent, each Debtor shall
assemble its Collateral and make it available to the Agent at any place
designated by the Agent that is reasonably convenient to it and the Agent. Each
Debtor agrees that the Agent shall not be obligated to give more than ten (10)
days prior written notice of the time and place of any public sale or of the
time after which any private sale may take place and that such notice shall
constitute reasonable notice of such matters. The Agent shall not be obligated
to make any sale of Collateral if it shall determine not to do so, regardless of
the fact that notice of sale of Collateral may have been given. The Agent may,
without notice or publication, adjourn any public or private sale or cause the
same to be adjourned from time to time by announcement at the time and place

                                                                             H-7

<PAGE>

fixed for sale, and such sale may, without further notice, be made at the time
and place to which the same was so adjourned. Each Debtor shall be liable for
all reasonable expenses of retaking, holding, preparing for sale or the like,
and all reasonable attorneys' fees, legal expenses and other costs and expenses
incurred by the Agent in connection with the collection of the Obligations and
the enforcement of the Agent's rights under this Agreement. Each Debtor shall
remain liable for any deficiency if the proceeds of any sale or other
disposition of the Collateral applied to the Obligations are insufficient to pay
the Obligations in full to the extent provided in the Transaction Documents. The
Agent shall apply the proceeds of Collateral against the Obligations as provided
in the Intercreditor Agreement. Each Debtor waives all rights of marshalling,
valuation and appraisal in respect of the Collateral. Any cash held by the Agent
as Collateral and all cash proceeds received by the Agent in respect of any sale
of, collection from or other realization upon all or any part of the Collateral
may, in the discretion of the Agent, be held by the Agent as collateral for, and
then or at any time thereafter applied in whole or in part by the Agent against,
the Obligations in the order permitted by the Intercreditor Agreement. The Agent
shall have no obligation to invest or otherwise pay interest on any amounts held
by it in connection with or pursuant to this Agreement or the Intercreditor
Agreement.

         (b)   The Agent may cause any or all of the Collateral held by it to be
transferred into the name of the Agent or the name or names of the Agent's
nominee or nominees.

         (c)   The Agent may exercise any and all of the rights and remedies of
any Debtor under or in respect of the Collateral, including, without limitation,
any and all rights of it to demand or otherwise require payment of any amount
under, or performance of any provision of, any of the Collateral.

         (d)   The Agent may collect or receive all money or property at any
time payable or receivable on account of or in exchange for any of the
Collateral, but shall be under no obligation to do so.

         (e)   On any sale of the Collateral, the Agent is hereby authorized to
comply with any limitation or restriction with which compliance is necessary, in
the view of the Agent's counsel, in order to avoid any violation of applicable
law or in order to obtain any required approval of the purchaser or purchasers
by any applicable governmental authority.

         (f)   For purposes of enabling the Agent to exercise its rights and
remedies under this Section 6.01 and enabling the Agent and its successors and
assigns to enjoy the full benefits of the Collateral in each case as the Agent
shall be entitled to exercise its rights and remedies under this Section 6.01,
each Debtor hereby grants to the Agent an irrevocable, nonexclusive license
(exercisable without payment of royalty or other compensation to it) to, if an
Event of Default exists, use, assign, license or sublicense any of its
intellectual property, including in such license reasonable access to all media
in which any of the licensed items may be recorded or stored and all computer
programs used for the completion or printout thereof and further including in
such license such rights of quality control and inspection as are reasonably
necessary to prevent the trademarks included in such license from claims of
invalidation. This license shall also inure to the benefit of all successors,
assigns and transferees of the Agent.

                                   ARTICLE VII
                                  MISCELLANEOUS

     Section 7.01 No Waiver; Cumulative Remedies. No failure on the part of the
Agent to exercise and no delay in exercising, and no course of dealing with
respect to, any right, power or

                                                                             H-8

<PAGE>

privilege under this Agreement shall operate as a waiver thereof, nor shall any
single or partial exercise of any right, power or privilege under this Agreement
preclude any other or further exercise thereof or the exercise of any other
right, power, or privilege. The rights and remedies provided for in this
Agreement are cumulative and not exclusive of any rights and remedies provided
by law.

     Section 7.02 Successors and Assigns. This Agreement shall be binding upon
and inure to the benefit of each Debtor and the Agent and respective successors
and assigns, except that no Debtor may assign any of its rights or obligations
under this Agreement without the prior written consent of the Creditors.

     Section 7.03 AMENDMENT; ENTIRE AGREEMENT. THIS AGREEMENT AND THE OTHER
TRANSACTION DOCUMENTS EMBODY THE FINAL, ENTIRE AGREEMENT AMONG THE PARTIES
HERETO AND SUPERSEDES ANY AND ALL PRIOR COMMITMENTS, AGREEMENTS, REPRESENTATIONS
AND UNDERSTANDINGS, WHETHER WRITTEN OR ORAL, 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. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES HERETO. Except
as contemplated by the execution and delivery of a Subsidiary Joinder Agreement
(which only needs to be signed by the party thereto), the provisions of this
Agreement may be amended or waived only by an instrument in writing signed by
the parties hereto and the number of Creditors required by the Intercreditor
Agreement.

     Section 7.04 Notices. All notices and other communications provided for in
this Agreement shall be given or made in accordance with the Intercreditor
Agreement.

     Section 7.05 Governing Law. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of Texas and applicable laws
of the United States of America.

     Section 7.06 Headings. The headings, captions, and arrangements used in
this Agreement are for convenience only and shall not affect the interpretation
of this Agreement.

     Section 7.07 Survival of Representations and Warranties. All
representations and warranties made in this Agreement or in any certificate
delivered pursuant hereto shall survive the execution and delivery of this
Agreement, and no investigation by the Agent shall affect the representations
and warranties or the right of the Agent or any Creditor to rely upon them.

     Section 7.08 Counterparts. This Agreement may be executed in any number of
counterparts and on facsimile counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same agreement.

     Section 7.09 Waiver of Bond. In the event the Agent seeks to take
possession of any or all of the Collateral by judicial process, each Debtor
hereby irrevocably waives any bonds and any surety or security relating thereto
that may be required by applicable law as an incident to such possession, and
waives any demand for possession prior to the commencement of any such suit or
action.

     Section 7.10 Severability. Any provision of this Agreement which is
determined by a court of competent jurisdiction to be prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions of this Agreement, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                                                                             H-9

     Section 7.11 Termination. If all of the Obligations shall have been paid
and performed in full, all commitments of the Agent and the Creditors under the
Transaction Documents shall have expired or terminated, the Agent shall, upon
the written request of a Debtor, execute and deliver to the Debtor a proper
instrument or instruments acknowledging the release and termination of the
security interests created by this Agreement, and shall duly assign and deliver
to each Debtor (without recourse and without any representation or warranty)
such of the Collateral as may be in the possession of the Agent and has not
previously been sold or otherwise applied pursuant to this Agreement.

     Section 7.12 Obligations Absolute. All rights and remedies of the Agent
hereunder, and all obligations of each Debtor hereunder, shall be absolute and
unconditional irrespective of:

         (a)   any lack of validity or enforceability of any of the Transaction
Documents;

         (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 any of the Transaction Documents;

         (c)   any exchange, release, or non-perfection of any Collateral, or
any release or amendment or waiver of or consent to any departure from any
guarantee, for all or any of the Obligations; or

         (d)   any other circumstance that might otherwise constitute a defense
available to, or a discharge of, a third party pledgor.

                                    [FORM OF]
                                PLEDGE AGREEMENT

     THIS PLEDGE AGREEMENT (this "Agreement") is made as of June 4, 2002, by
TRINITY INDUSTRIES, INC., a Delaware corporation [Subsidiary] ("Pledgor"), in
favor of JPMORGAN CHASE BANK, as collateral agent (in such capacity, "Secured
Party") for certain parties under the hereafter defined Intercreditor Agreement.

                                    RECITALS:

     Pledgor, Secured Party and certain other parties have entered into that
certain Intercreditor Agreement dated as of June 4, 2002 (as the same may be
amended, restated or otherwise modified from time to time, the "Intercreditor
Agreement"). This Agreement is executed pursuant to the terms of the
Intercreditor Agreement and as required by the terms of the Transaction
Documents (as such term is defined in the Intercreditor Agreement).

     NOW, THEREFORE, in consideration of the premises and for other good and
valuable consideration, the adequacy, receipt and sufficiency of which are
hereby acknowledged, and in fulfillment of the requirements of the Transaction
Documents, the parties hereto hereby agree as follows:

     1.   AGREEMENT.

          (a)  Pledge. Upon the terms hereof, for value received, Pledgor hereby
irrevocably and unconditionally pledges, assigns, hypothecates and transfers to
Secured Party, for the ratable benefit of the Creditors a party to the
Intercreditor Agreement, a first and prior pledge and security interest in (1)
all capital stock, equity and other ownership interests of
______________________________, ___________________________,
____________________________ and ________________________ (collectively, the
"Pledged Equity Issuers") owned beneficially or of record by Pledgor, and
described on Exhibit A attached hereto (together with any certificate or
instrument evidencing such interest) (the foregoing interests being referred to
herein as the "Pledged Equity"), (2) any and all proceeds or other sums arising
from or by virtue of, and all dividends and distributions (cash or otherwise)
payable and/or distributable with respect to, all or any of the Pledged Equity,

time to time receivable or otherwise distributed in respect of or in exchange
for any or all of the Pledged Equity and any other property substituted or
exchanged therefor (all of the foregoing described in clauses (1), (2) and (3)
being collectively referred to herein as the "Collateral"). Unless otherwise
defined in this Agreement, terms used herein shall have the meanings set forth
in the Intercreditor Agreement or the Revolver/Term Agreement (as defined in the
Intercreditor Agreement) as the context shall require. Notwithstanding any
contrary provision in this Agreement, however, the pledge hereunder is limited
to the extent, if any, required so that such pledge is not subject to avoidance
under applicable bankruptcy or other debtor relief laws.

     2.   OBLIGATIONS. The following obligations (collectively, the
"Obligations") are secured by this Agreement:

          (a)  All Obligations (as such term is defined in the Intercreditor
Agreement).

Party to obtain, preserve, perfect and enforce this Agreement, the other
Transaction Documents, and the pledge and

                                                                             I-1

security interest granted hereby, collect the Obligations, and maintain,
preserve, collect and enforce the Collateral, including, without limitation,
taxes, assessments, attorneys' fees and legal expenses, and expenses of sale.

          (c)  Interest on the above amounts as agreed to by Pledgor under the
Transaction Documents, including, without limitation, interest, fees and other
charges that would accrue or become owing both prior to and subsequent to and
but for the commencement of any proceeding against or with respect to Pledgor
under any chapter of the Bankruptcy Code of 1978, 11 U.S.C. ss. 101 et seq.
whether or not a claim is allowed for the same in any such proceeding.

     3.   COVENANTS, REPRESENTATIONS AND WARRANTIES.

               (1)  Representations and Warranties Concerning Pledgor. Pledgor

     interest created hereby (including the first priority nature of such

     the Collateral and the operations of its business; (E) Pledgor is not, nor

     other contractual obligation of Pledgor; (F) except as disclosed in the

     counterclaim or defense exists with respect to any part of the Collateral.
     The delivery at any time by Pledgor to Secured Party of Collateral shall
     constitute a representation and warranty by Pledgor under this Agreement
     that, (i) with respect to such Collateral, and each item thereof, Pledgor
     is the sole legal and beneficial owner of, with good title to, the
     Collateral, and (ii) the matters warranted in this paragraph are true and
     correct.

                                                                             I-2

     documents or agreements evidencing any of the Collateral; (B) from time to

     interest and pledge herein created or to effect the purposes of this
     Agreement; (C) promptly to furnish Secured Party with any information or
     writings which Secured Party or any Creditor may reasonably request

     take away copies of such records, at Pledgor's expense, at such reasonable
     times and as often as may be reasonably requested by Secured Party or any
     such Creditor; (E) promptly to notify Secured Party of any change in any
     fact or circumstances warranted or represented by Pledgor in this Agreement
     or in any other writings furnished by or on behalf of Pledgor to Secured
     Party or any Creditor in connection with the Collateral; (F) promptly to
     notify Secured Party of any claim, action or proceeding affecting title to
     the Collateral, or any part thereof, or the security interest therein, and,
     at the request of Secured Party, appear in and defend, at Pledgor's
     expense, any such action or proceeding; and (G) promptly to pay to Secured
     Party the amount of all costs and attorneys' fees incurred by Secured Party

     Revolver/Term Agreement, Pledgor covenants and agrees that Pledgor will not
     (A) sell, assign or transfer any of Pledgor's rights in the Collateral; (B)
     create any other security interest or pledge in, mortgage or otherwise
     encumber the Collateral or any part thereof, or permit the same to be or
     become subject to any Lien, attachment, execution, sequestration, other
     legal or equitable process, or any encumbrance of any kind or character,
     except for Liens permitted by Section 7.02 of the Revolver/Term Agreement;
     (C) approve any amendment to the certificate or articles of incorporation,
     the bylaws, or other charter documents of any Pledged Equity Issuer (other
     than ministerial amendments which would not adversely affect the rights of
     Secured Party or the Creditors hereunder).

     Notwithstanding anything to the contrary contained herein, in the event of
any conflict between the terms and provisions of this Section 3(b) and the terms
and provisions of Article VI or Article VII of the Revolver/Term Agreement, the
terms and provisions of Article VI and/or Article VII of the Revolver/Term
Agreement shall control.

     4.   RIGHTS OF SECURED PARTY.

          (a)  Rights to Dividends, Distributions, and Payments. With respect to
such instruments which are certificates, bonds or other securities, Secured
Party may demand of the obligor issuing the same, and may receive and receipt
for, any and all dividends and other distributions (other than cash dividends)
payable in respect thereof, whether ordinary or extraordinary. Secured Party
shall have the authority, following the occurrence and during the continuance of
an Event of Default and without notice to Pledgor, to have such certificates,
bonds or other securities registered either in Secured Party's name or in the
name of a nominee. If, while this Agreement is in effect, Pledgor shall become
entitled to receive or shall receive any certificate (including, without
limitation, any certificate representing a stock or ownership interest dividend
or a distribution in connection with any reclassification, increase or reduction
of capital, or issued in connection with any reorganization), option

                                                                             I-3

<PAGE>

or rights, whether as an addition to, in substitution of, as a conversion of or
in exchange for any of the Collateral, or otherwise, Pledgor agrees to accept
the same as Secured Party's agent and to hold the same in trust on behalf of and
for the benefit of Secured Party, and to deliver the same forthwith to Secured
Party in the exact form received, with appropriate undated stock powers, duly
executed in blank, to be held by Secured Party, subject to the terms hereof, as
additional collateral security for the Obligations. Until and unless an Event of
Default shall have occurred and be continuing, Pledgor shall be entitled to
receive and utilize all cash dividends, principal, and interest paid in respect
of the Collateral. After the occurrence and during the continuance of an Event
of Default, Secured Party shall be entitled to all cash dividends and to any
sums paid upon or in respect of the Collateral upon the liquidation, dissolution
or reorganization of the issuer thereof which shall be paid to Secured Party to
be held by it as additional collateral security for the Obligations. In case any
distribution shall be made on or in respect of the Collateral pursuant to the
reorganization, liquidation or dissolution of the issuer thereof, the property
so distributed shall be delivered to Secured Party to be held by it as
additional collateral security for the Obligations. After the occurrence and
during the continuance of an Event of Default, all sums of money and property so
paid or distributed in respect of the Collateral (other than proceeds of any
liquidation or similar proceeding) which are received by Pledgor shall, until
paid or delivered to Secured Party, be held by Pledgor in trust as additional
Collateral for the Obligations.

          (b)  Preservation of Collateral. Neither Secured Party nor any
Creditor shall have any duty to fix or preserve rights against prior parties to
the Collateral, nor be liable for any delay in the collection of, or failure to
use diligence to collect on, the Obligations or any amount payable in respect of
the Collateral.

          (c)  Performance by Secured Party. Should any covenant, duty or
agreement of Pledgor fail to be performed in accordance with its terms
hereunder, Secured Party may, but shall never be obligated to, perform or
attempt to perform such covenant, duty or agreement on behalf of Pledgor, and
any amount expended by Secured Party in such performance or attempted
performance shall become a part of the Obligations, shall be payable upon demand
and shall bear interest at a per annum rate equal to the lesser of (1) the
Highest Lawful Rate, or (2) the rate set forth in Section 2.13(d) of the
Revolver/Term Agreement.

          (d)  Voting Rights. It is expressly understood and agreed that Pledgor
shall retain all voting rights to the Collateral until the occurrence and during
the continuance of an Event of Default, at which time such voting rights for
purposes of collateral preservation shall transfer to Secured Party, at its sole
discretion and in accordance with Section 4(e) hereof; provided, however, that
no voting, corporate or management rights shall be exercised or vote cast or
consent, waiver or ratification given or action taken by Pledgor that would
impair the Collateral or be inconsistent with or violate any provision of this
Agreement or any other Transaction Documents.

CONTINUANCE OF AN EVENT OF DEFAULT WHICH IS CONTINUING) TO VOTE ANY COLLATERAL
AND APPOINTS SECURED PARTY AS PLEDGOR'S ATTORNEY-IN-FACT TO PERFORM ALL
OBLIGATIONS OF PLEDGOR UNDER THIS AGREEMENT AND TO EXERCISE ALL OF SECURED

     5.   DEFAULT.

          (a)  Rights and Remedies. Upon the occurrence and during the
continuance of an Event of Default, in addition to any and all other rights and
remedies which Secured Party or any Creditor may then have hereunder, under any
other Transaction Documents, under applicable law or otherwise, Secured Party at
its option may, subject to any limitation or restriction imposed by any
applicable bankruptcy, insolvency or other law relating to the relief of
debtors, (1) obtain from any Person information regarding Pledgor, any issuer of
the Collateral, or any of their businesses, which information any such Person
may furnish without liability to Pledgor; (2) require Pledgor to give possession
or control of any of the Collateral to Secured Party; (3) unless earlier
permitted hereunder, take control of funds generated by the Collateral and any
other proceeds and exercise all other rights which an owner of such Collateral
may exercise; (4) declare the entire unpaid balance of principal and interest on
the Obligations immediately due and payable, without notice, demand or
presentment, which are hereby expressly waived; (5) reduce its claim to
judgment, foreclose or otherwise enforce its security interest in all or any
part of the Collateral by any available judicial procedure; (6) after
notification, if any, provided for in this Agreement or any other Transaction
Documents, sell or otherwise dispose of, at the office of Secured Party, all or
any part of the Collateral, and any such sale or other disposition shall be in
accordance with applicable law, and may be as a unit or in parcels, by public or
private proceedings, and by way of one or more contracts (it being agreed that
the sale of any part of the Collateral shall not exhaust Secured Party's power
of sale, but sales may be made from time to time until all of the Collateral has
been sold or until the Obligations have been paid in full), and at any such sale
it shall not be necessary to exhibit the Collateral; (7) at its discretion,
retain the Collateral in satisfaction of the Obligations whenever the
circumstances are such that Secured Party is entitled to do so under applicable
law; (8) apply by appropriate judicial proceedings for appointment of a receiver
for the Collateral, or any part hereof, and Pledgor hereby consents to any
appointment; (9) buy the Collateral at any public sale; and (10) buy the
Collateral at any private sale, subject to any restrictions imposed by
applicable law. Pledgor agrees that, if notice is required to be given by
applicable law, ten days' advance written notice shall constitute reasonable
notice. Secured Party shall apply the proceeds of any collection, sale,
disposition or other realization upon any Collateral as follows:

          First, to the payment of the costs and expenses of such collection,
          sale, disposition, or other realization, including reasonable
          out-of-pocket costs and expenses of Secured Party and the fees and
          expenses of its agents and counsel;

          Next, to the payment of the Obligations, as provided in the
          Intercreditor Agreement, and in such manner consistent with applicable
          laws as Secured Party in its discretion shall decide; and

          Finally, to the payment to Pledgor, or its successors or assigns, or
          as a court of competent jurisdiction may direct, of any surplus then
          remaining.

     If the proceeds of collection, sale, disposition, or other realization are
     insufficient to cover the costs and expenses of such realization and the
     payment in full of the Obligations, Pledgor shall remain liable for any
     deficiency.

          (b)  Securities Laws; Transfer.

               (1)  Immediately upon the occurrence and during the continuance
     of an Event of Default, Pledgor hereby grants to Secured Party the right to
     have the Collateral, or any portion thereof, registered and sold under the
     Securities Act of 1933, as amended ("Securities

                                                                             I-5

     Act"), or under any applicable state blue sky laws. If Secured Party shall
     determine to exercise its right to sell any or all of the Collateral
     pursuant to the terms hereof, and if in the reasonable opinion of Secured
     Party it is necessary or advisable to have the Collateral (or that portion
     thereof to be sold) registered under the provisions of the Securities Act,
     Pledgor will cause the issuer of the Collateral to execute and deliver, and
     cause the directors and officers thereof to execute and deliver, all at
     Pledgor's and/or such issuer's expense, all such instruments and documents,
     and to do or cause to be done all such other acts and things as may be
     necessary or, in the opinion of Secured Party, advisable to register such
     Collateral under the provisions of the Securities Act and to cause the
     registration statement relating thereto to become effective and to remain
     effective for a period of one year from the date of the first public
     offering of such Collateral, or that portion thereof to be sold, and to
     make all amendments thereto and/or to the related prospectus which, in the
     opinion of Secured Party, are necessary or advisable, all in conformity
     with the requirements of applicable law. Pledgor agrees to cause the issuer
     of the Collateral to comply with the provisions of the securities or "blue
     sky" laws of any jurisdiction which Secured Party shall designate and to
     cause the issuer of the Collateral to make available to its security
     holders, as soon as practicable, an earnings statement which will satisfy
     the provisions of Section 11(a) of the Securities Act.

               (2)  Pledgor recognizes that Secured Party may be unable to
     effect a public sale of any or all of the Collateral by reason of certain
     prohibitions contained in the Securities Act and applicable state
     securities laws, but may be compelled to resort to one or more private
     sales thereof to a restricted group of purchasers who will be obliged to
     agree, among other things, to acquire such Collateral for their own account
     for investment and not with a view to the distribution or resale thereof.
     Pledgor acknowledges and agrees that any such private sale conducted in the
     manner described herein may result in prices and other terms less favorable
     to the seller than if such sale were a public sale and, notwithstanding
     such circumstances, agrees that any private sale shall be made in a
     commercially reasonable manner. Secured Party shall be under no obligation
     to delay a sale of any of the Collateral for the period of time necessary
     to permit the issuer of the Collateral to register such Collateral for
     public sale under the Securities Act, or under applicable state securities
     laws, even if the issuer of the Collateral would agree to do so.

               (3)  Pledgor further agrees to do or cause to be done all such
     other acts and things as may be necessary to make any sales of any portion
     or all of the Collateral pursuant to paragraphs (b)(1) and (b)(2) of this
     Section 5 valid and binding and in compliance with any and all applicable
     laws (including, without limitation, the Securities Exchange Act of 1934,
     as amended, and the rules and regulations of the Securities and Exchange
     Commission applicable thereto), regulations, orders, writs, injunctions,
     decrees or awards of any and all courts, arbitrators or governmental
     instrumentalities, domestic or foreign, having jurisdiction over any such
     sale or sales, all at Pledgor's expense. Pledgor further agrees that a
     breach of any of the covenants contained in this Section 5 will cause
     irreparable injury to Secured Party and that Secured Party may not have an
     adequate remedy at law in respect of such breach. As a consequence, Pledgor
     agrees that each and every covenant contained in this Section shall be
     specifically enforceable against Pledgor. To the extent permitted by
     applicable law, Pledgor hereby waives and agrees not to assert any defenses
     against an action for specific performance of such covenants.

               (4)  Pledgor agrees (A) that in the event Secured Party shall,
     upon any Event of Default, sell the Collateral or any portion thereof, at a
     private sale or sales, Secured Party shall have the right to rely upon the
     advice and opinion of a member of a nationally recognized

                                                                             I-6

<PAGE>

     investment banking firm acceptable to Secured Party, as to the best price
     reasonably obtainable upon such a private sale thereof, and (B) in the
     absence of fraud, willful misconduct and gross negligence, that such
     reliance shall be conclusive evidence that Secured Party handled such
     matter in a commercially reasonable manner under the UCC.

          (c)  Governmental Approvals. In connection with the exercise by
Secured Party of its rights hereunder, it may be necessary to obtain the prior
consent or approval of a Governmental Authority or other Persons to the exercise
of rights with respect to the Collateral, and any representations and warranties
made by Pledgor herein shall be deemed appropriately amended to reflect this
fact. Pledgor hereby agrees to execute, deliver and file, and hereby appoints
(to the extent permitted under applicable law) Secured Party as its attorney to
execute, deliver and file on Pledgor's behalf and in Pledgor's name, all
applications, certificates, filings, instruments and other documents (including
without limitation any application for an assignment or transfer of control or
ownership) that may be necessary or appropriate, in Secured Party's opinion, to
obtain such consents or approvals. Pledgor further agrees to use its best
efforts to obtain such consents or approvals. Pledgor acknowledges that there is
no adequate remedy at law for failure by it to comply with the provisions of
this Section and that such failure would not be adequately compensable in
damages, and therefore agrees that Pledgor's efforts to obtain any approval
required by this Section may be specifically enforced.

          (d)  Notice. Notification of the time and place of any public sale of
the Collateral, or reasonable notification of the time after which any private
sale or other intended disposition of the Collateral is to be made, shall be
sent to Pledgor and to any other Person entitled under applicable law to notice.

     6.   GENERAL.

          (a)  Secured Party's Duties. The Creditors have appointed Secured
Party to act as their agent as provided herein. In the event Secured Party is
replaced pursuant to Section 6.04 of the Intercreditor Agreement, the successor
Secured Party appointed in accordance with Section 6.04 of the Intercreditor
Agreement shall be the Secured Party hereunder. The powers conferred on Secured
Party hereunder are solely to protect the Creditors interest in the Collateral
and shall not impose any duty upon it to exercise any such powers. Except for
the safe custody of any Collateral in its possession and the accounting for
moneys actually received by it hereunder, Secured Party shall have no duty as to
any Collateral, as to ascertaining or taking action with respect to calls,
conversions, exchanges, maturities, tenders, or other matters relative to any
Collateral, whether or not Secured Party or any Creditor has or is deemed to
have knowledge of such matters, or as to the taking of any necessary steps to
preserve rights against prior parties or any other rights pertaining to any
reasonable care in the custody and preservation of any Collateral in its
possession if such Collateral is accorded treatment substantially equal to that
which Secured Party accords its own property. Except as set forth herein Secured
Party shall not have any duty or liability to protect or preserve any Collateral
or to preserve rights pertaining thereto. Nothing contained in this Agreement
shall be construed as requiring or obligating Secured Party, and Secured Party
shall not be required or obligated, (1) to present or file any claim or notice
or take any action, with respect to any Collateral or in connection therewith or
(2) to notify Pledgor of any decline in the value of any Collateral.

          (b)  Cumulative Rights. All rights and remedies of Secured Party
hereunder are cumulative of each other and of every other right or remedy which
Secured Party may otherwise have at law or in equity or under any other contract
or other writing for the enforcement of the security interest herein or the
collection of the Obligations, and the exercise of one or more rights or
remedies shall not prejudice or impair the concurrent or subsequent exercise of
other rights or remedies.

                                                                             I-7

<PAGE>

          (c)  Waiver. Should any part of the Obligations be payable in
installments, the acceptance by any Creditor at any time and from time to time
of partial payment of the aggregate amount of all installments then matured
shall not be deemed as a waiver of any Event of Default then existing. No waiver
by Secured Party or any Creditor of any Event of Default shall be deemed to be a
waiver of any other subsequent Event of Default, nor shall any such waiver by
Secured Party be deemed to be a continuing waiver. No delay or omission by
Secured Party or any Creditor in exercising any right or power hereunder, or
under any other Transaction Documents, shall impair any such right or power or
be construed as a waiver thereof or an acquiescence therein, nor shall any
single or partial exercise of any such right or power preclude other or further
exercise thereof, or the exercise of any other right or power of Secured Party
or any Creditor hereunder or under such other writings.

          (d)  Interest; Limitation of Law. No provision herein or in any
Transaction Document shall require the payment or permit the collection of
interest in excess of the maximum permitted by applicable law. If, in any
contingency whatsoever, Secured Party or any Creditor shall receive anything of
value from Pledgor deemed interest under applicable law which would exceed the
maximum amount of interest permissible under applicable law, the provisions of
the Transaction Documents shall govern.

          (e)  Parties Bound. This Agreement shall be binding on Pledgor and its
successors, assigns and legal and personal representatives, administrators,
executors, beneficiaries and heirs and shall inure to the benefit of Secured
Party and the Creditors, and their successors, assigns and legal
representatives; provided, however, that Pledgor may not assign its rights or
obligations hereunder without the prior written consent of Secured Party. The
rights, powers and interests held by Secured Party hereunder may be transferred
and assigned by Secured Party, in whole or in part, at such time and upon such
terms as permitted by the Transaction Documents.

          (f)  Notice. All notices, requests and other communications to any
party hereunder shall be in writing (including, telecopy or similar
teletransmission or writing) and shall be given to such party at its address or
telecopy number set forth on the signature pages hereof or such other address or
telecopy number as such party may hereafter specify by notice to the other
party. Each such notice, request or other communication shall be effective (1)
if given by mail, 72 hours after such communication is deposited in the mails
with first class postage prepaid, addressed as aforesaid, or (2) if given by any
other means (including, but not limited to, by air courier), when delivered at
the address specified in this Section 6(f); provided that notices to Secured
Party shall not be effective until actually and physically received.

          (g)  Waivers by Pledgor. Pledgor waives notices of the creation,
advance, increase, existence, extension or renewal of, and of any indulgence
with respect to, the Obligations; waives presentment, demand, notice of dishonor
and protest; waives notice of the amount of the Obligations outstanding at any
time, notice of any change in financial condition of any Person liable for the
Obligations or any part thereof, notice of any Event of Default and all other
notices respecting the Obligations; waives all rights of redemption, appraisal,
or valuation; and agrees that maturity of the Obligations and any part thereof
may be accelerated, increased, extended or renewed one or more times by Secured
Party in their discretion, without notice to Pledgor.

          (h)  Modifications. No provision hereof shall be modified or limited
except by a written agreement expressly referring hereto and to the provisions
so modified or limited and signed by Secured Party, nor by course of conduct,
usage of trade or mercantile law.

                                                                             I-8

<PAGE>

          (i)  Control. Notwithstanding anything herein to the contrary, this
Agreement and the transactions contemplated hereby do not and will not
constitute, create, or have the effect of constituting or creating, directly or
indirectly, actual or practical ownership of Pledgor or the issuer of the
Collateral by Secured Party, or control, affirmative or negative, direct or
indirect, by Secured Party, over the management or any aspect of the day-to-day
operation of Pledgor or the issuer of the Collateral, which control remains in
Pledgor, the issuer of the Collateral, and their respective shareholders and
boards of directors.

          (j)  Governing Law; Submission to Jurisdiction; etc.

               (1)  Governing Law. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS
     OF THE PARTIES HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND BE
     GOVERNED BY THE LAWS OF THE STATE OF TEXAS AND, TO THE EXTENT CONTROLLING,
     LAWS OF THE UNITED STATES OF AMERICA.

               (2)  Submission to Jurisdiction. ANY LEGAL ACTION OR PROCEEDING
     WITH RESPECT TO THIS AGREEMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF
     TEXAS OR OF THE UNITED STATES OF AMERICA FOR THE NORTHERN DISTRICT OF
     TEXAS, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, PLEDGOR HEREBY
     ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND
     UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. PLEDGOR HEREBY
     IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, BUT NOT LIMITED TO, ANY
     OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON
     CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH
     ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS.

               (3)  Waiver of Jury Trial and Consequential Damages. TO THE
     MAXIMUM EXTENT ALLOWED BY APPLICABLE LAW, EACH OF PLEDGOR AND SECURED PARTY
     (A) IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL
     ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY TRANSACTION DOCUMENT
     AND FOR ANY COUNTERCLAIM THEREIN, (B) IRREVOCABLY WAIVES ANY RIGHT IT MAY
     HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY SPECIAL, EXEMPLARY,
     PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION
     TO, ACTUAL DAMAGES; (C) CERTIFIES THAT NO PARTY HERETO NOR ANY
     REPRESENTATIVE OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY
     OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF
     LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER; AND (D) ACKNOWLEDGES THAT
     IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE TRANSACTIONS
     CONTEMPLATED HEREBY BASED UPON, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
     CERTIFICATIONS CONTAINED IN THIS SECTION.

               (4)  Service of Process. Pledgor irrevocably consents to service
     of process in the manner provided for notices in Section 6(f). Nothing
     herein shall affect the right of Secured Party or any Creditor to serve
     process in any other manner permitted by law or to commence legal
     proceedings or otherwise proceed against Pledgor in any other jurisdiction.

                                                                             I-9

          (k)  Entire Agreement. THIS AGREEMENT, TOGETHER WITH THE OTHER
TRANSACTION DOCUMENTS, REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES WITH
RESPECT TO THE SUBJECT MATTER HEREOF AND MAY NOT BE CONTRADICTED BY EVIDENCE OF
PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES HERETO.
THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

     IN WITNESS WHEREOF, Pledgor has executed this Agreement as of the date
first above written.
