                                   THE CREDITS

         SECTION 2.01 Revolving Commitment. Subject to the terms and conditions
set forth herein, each Lender agrees to make Revolving Loans to the Borrower
from time to time during the Availability Period in an aggregate principal
amount that will not result in (i) such Lender's Revolving Credit Exposure
exceeding such Lender's Revolving Commitment or (ii) the sum of the Aggregate
Revolving Credit Exposure plus the aggregate principal amount of outstanding
Competitive Loans exceeding the Aggregate Revolving Commitment. Within the
foregoing limits and subject to the terms and conditions set forth herein, the
Borrower may borrow, prepay and reborrow Revolving Loans.

         SECTION 2.02 Revolving Loans and Borrowings.

         (a)      Each Revolving Loan shall be made as part of a Borrowing
consisting of Revolving Loans made by the Lenders ratably in accordance with
their respective Revolving 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 Revolving 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 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.

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

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 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 Lender of the details thereof and of the
amount of such 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

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

                                       27
<PAGE>

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 Lenders of the details
thereof by telecopy, inviting the Lenders to submit Competitive Bids.

                  (b)      Each 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 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 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 Lender is willing to make, (ii) the Competitive Bid Rate or
Competitive Bid Rates at which the 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

<PAGE>

                  (d)      Subject only to the provisions of this Section
2.04(d), the Borrower may accept or reject any Competitive Bid. The Borrower

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 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 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 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 Lenders are required to submit their Competitive Bids to
the Administrative Agent pursuant to paragraph (b) of this Section 2.04.

                  (g)      Any 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 Lender a
promissory note payable to the order of such 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

                                       29
<PAGE>

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 deemed to represent and warrant that), after giving effect to
such issuance, amendment, renewal or extension (i) the LC Exposure shall not
exceed $150,000,000, (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 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 Lenders, the
Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from
the Issuing Bank, a participation in such Letter of Credit equal to such
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 Lender hereby absolutely and unconditionally agrees to pay to
the Administrative Agent, for the account of the Issuing Bank, such 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 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

                                       30
<PAGE>

termination of the Revolving 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 Lender of the applicable LC
Disbursement, the payment then due from the Borrower in respect thereof and such
Lender's Revolving Credit Percentage thereof. Promptly following receipt of such
notice, each 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 Lender (and Section
2.06 shall apply, mutatis mutandis, to the payment obligations of the 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 Lenders have made payments pursuant to this Section
2.05(e) to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank
as their interests may appear. Any payment made by a 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

                                       31
<PAGE>

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 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 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 Lender pursuant to paragraph (e) of this Section 2.05 to reimburse the
Issuing Bank shall be for the account of such 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 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

                                       32

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 Lenders (or, if the
maturity of the Revolving Loans has been accelerated, 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 Borrower
shall deposit in an account with the Administrative Agent, in the name of the
Administrative Agent and for the benefit of the 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 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 Lender prior to the proposed date of any Borrowing that such
Lender will not make available to the Administrative Agent such Lender's share
of such Borrowing, the Administrative Agent may assume that such 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 event, if a Lender has not in fact made
its share of the applicable Borrowing available to the Administrative Agent,
then the applicable 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 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 Lender
pays such amount to the Administrative Agent, then such amount shall constitute
such 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

                                       34
<PAGE>

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

                  (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 Revolving Credit Notes. The Borrower's obligation to pay
the principal of, and interest on, the Revolving Loans made by each 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 Lender in the amount of
such 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.

                                       35

         SECTION 2.09 Termination and Reduction of Revolving Commitments;
Certain Prepayments.

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

                  (b)      In the event the Borrower shall 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 reduction of the Revolving Commitments as set forth in Section
2.11(e).

                  (c)      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(b),
the sum of the Aggregate Revolving Credit Exposure plus the aggregate principal
amount of outstanding Competitive Loans would exceed the Aggregate Revolving
Commitment.

                  (d)      The Borrower shall notify the Administrative Agent of
any election to terminate or reduce the Revolving Commitments under paragraph
(c) 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 Lenders of the contents thereof. Each
notice delivered by the Borrower pursuant to this Section 2.09(d) 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. Subject to
Section 2.21, any termination or reduction of the Revolving Commitments shall be
permanent. Each reduction of the Revolving Commitments shall be made ratably
among the 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 Lender the then unpaid
principal amount of each Revolving Loan and Borrowing of such Lender on the
Revolving Commitment Termination Date, (ii) to the Administrative Agent for the
account of each Lender thereof, the then unpaid principal amount of each
Competitive Loan on the last day of the Interest Period applicable to such
Competitive Loan, and (iii) 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.

                                       36
<PAGE>

                  (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 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)      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(a) 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(a) 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 Lender thereof.

                  (b)      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.

                  (c)      At any time the Borrower becomes obligated to prepay
all or part of the Senior Unsecured Notes, the Borrower shall, prior to any
prepayment of the Senior Unsecured Notes, prepay the Loans and reduce the
Revolving Commitments in full.

                  (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

                                       37
<PAGE>

notice of prepayment is given in connection with a conditional notice of
termination of the Revolving Commitments as contemplated by Section 2.09(d),
then such notice of prepayment may be revoked if such notice of termination is
revoked in accordance with Section 2.09(d). 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.

                  (e)      Amounts to be applied in connection with Revolving
Commitment reductions made pursuant to Section 2.09(b) shall be applied to
reduce permanently the Revolving Commitments, any such reduction to be applied
proportionately to the Revolving Commitment of each 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(b). 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 Revolving
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 Lender a facility fee, which shall accrue at the
Applicable Rate on the daily amount of the Revolving Commitment of such 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
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 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 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 Lender's
Revolving Commitment terminates and the date on which such 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

                                       38
<PAGE>

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).

                  (c)      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).

                  (d)      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 and participation fees, to the 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 plus the Applicable
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 Alternate Base Rate.

                  (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
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

                                       39
<PAGE>

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:

                  (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

                                       40
<PAGE>

                  (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 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

                                       41
<PAGE>

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.

                  (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

                                       42
<PAGE>

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
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 or participation fee in respect of the
Revolving Commitments hereunder shall be allocated by the Administrative Agent,
and any reduction of the Revolving

                                       43
<PAGE>

Commitments of the Lenders shall be allocated by the Administrative Agent, pro
rata according to the relevant Revolving Credit Percentages of the 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 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 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

                                       44
<PAGE>

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 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

                                       45
<PAGE>

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 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.

         SECTION 2.21 Increase of Commitments. By delivery of an effective
Increase Notice to the Administrative Agent (which the Administrative Agent
shall promptly distribute to the Lenders), the Borrower may request an increase
of the aggregate amount of the Revolving Commitments; provided, that, (a) the
aggregate amount of the Revolving Commitments both before and after giving
effect to such requested increase shall not exceed $300,000,000, (b) no

                                       46
<PAGE>

Default or Event of Default shall have occurred and be continuing or would
result therefrom, and (c) the Borrower shall cause to be delivered to the
Administrative Agent a commitment (or commitments) from (i) at least one Lender
that commits to lending to the Borrower more than its then current Revolving
Commitment (such Lender to be referred to herein as a "Current Lender" and such
amount of its Revolving Commitment above its then current Revolving Commitment
to be referred to herein as a "Revolving Commitment Supplement") and/or (ii) any
other Person (including a Lender Affiliate) that meets the requirements of the
definition of "Eligible New Lender" (as defined in Section 1.01 hereof) and that
commits to lending to the Borrower and becoming a Lender under this Agreement
(such Person to be referred to herein as a "New Lender" and the amount of its
Revolving Commitment to be referred to herein as a "New Revolving Commitment")
(each Current Lender and each New Lender to be referred to herein collectively
as the "Supplementing Lenders"). Upon receipt of notice from the Administrative
Agent to the Lenders and the Borrower that the Supplementing Lenders have agreed
to commit to increase the Aggregate Revolving Commitments by an aggregate amount
equal to the Increase Amount and execution and delivery by the Borrower, the
Administrative Agent and the Supplementing Lenders of an Increased Commitment
Agreement evidencing such agreement, then (A) the then current Aggregate
Revolving Commitments shall be increased by the Increase Amount, (B) the then
current Revolving Commitment of each Current Lender shall be increased by such
Current Lender's Revolving Commitment Supplement and (C) each of the New Lenders
will be added as a Lender under this Agreement and each such New Lender's
Revolving Commitment shall be such New Lender's New Revolving Commitment. On the
effective date of the Increased Commitment Agreement, the Borrower shall request
a Borrowing hereunder, which Borrowing shall be made by (and only by) the
Supplementing Lenders in the appropriate amounts as provided below. The proceeds
of such Borrowing shall be utilized by the Borrower to repay the Lenders that
did not agree to increase their Revolving Commitments, such Borrowing and
repayment to be in amounts sufficient so that, after giving effect to the
Increased Commitment Agreement, the Revolving Loans and the LC Exposure shall be
held by the Lenders according to their Revolving Credit Percentage of the
Revolving Commitments as increased in accordance with the Increased Commitment
Agreement.

                                   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 (which representations and warranties shall be deemed made after giving
effect to the Closing Transactions (except in the case of Section 3.04(a)) 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.

                                       47
<PAGE>

         SECTION 3.02 Authorization; Enforceability. The Transactions and
Closing Transactions are within the Borrower's and each Material Subsidiary's
(as applicable) corporate, partnership or limited liability company powers (as
applicable) and have been duly authorized, as applicable, 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 and
Closing 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 calendar year ended December 31, 2003, 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 September 30,
2003, 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, 2003, 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.

                                       48
<PAGE>

                  (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,
the Transactions or the Closing 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.

         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

                                       49
<PAGE>

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.

         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

                                       50
<PAGE>

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 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 Closing Documents. The Borrower has provided to the
Administrative Agent a true, correct and complete copy of each of the Closing
Documents (and all amendments thereto) and all other material documents,
instruments and agreements entered into by, between or among the Borrower, its
Subsidiaries and any other party to any Closing Document, including all
amendments and modifications thereto (whether characterized as an amendment,
modification, waiver, consent or similar document) relating to the Closing
Transactions.

"Senior Indebtedness" of the Borrower under and as defined in the Indenture.

                                   ARTICLE IV

amendment, renewal or extension of any Letter of Credit and all other Borrowings

Revolving Commitment.

                  (d)      Following the issuance of any Letter(s) of Credit,
the aggregate LC Exposure of all the Lenders shall not exceed $150,000,000.

(c) and (d) of this Section 4.02.

                                    ARTICLE V
                                    SECURITY

         SECTION 5.01 Lender Indebtedness Secured. As of the Effective Date, and
at all times thereafter when the ratings established by S&P and Moody's for the
Index Debt (the "Index Debt Ratings") are at a level (as established in
accordance with the terms of this Section 5.01) equal to or below the Security
Threshold Rating Level, the Lender Indebtedness and the other obligations
described in the Intercreditor Agreement shall be secured by perfected, first
priority Liens on and encumbering (a) all accounts receivable and inventory
(other than the Excluded Collateral) of the Borrower and its Material
Subsidiaries party to the Security Agreements, whether now owned or hereafter
acquired and wherever located, and (b) all of the issued and outstanding Equity
owned by the Borrower and its Subsidiaries of each existing and future Material
Subsidiary. In furtherance of the foregoing, the Borrower hereby agrees to
execute and deliver (and to cause any other appropriate Person to execute and
deliver) to the Administrative Agent and/or the Collateral Agent for the benefit
of the Lenders and the Creditors (as defined in the Intercreditor Agreement),
promptly upon request by the Administrative Agent and/or the Collateral Agent,
such Security Instruments and other documents, instruments, agreements and
certificates, as the Administrative Agent and/or the Collateral Agent shall deem
necessary or appropriate in its or their sole discretion to create, evidence and
perfect the Liens contemplated by this Section 5.01. The Borrower hereby
consents and authorizes the Administrative Agent and the Collateral Agent, and
their agents, successors and assigns, to file any and all necessary financing
statements under the UCC, amendments, "in lieu" filings or assignments or

                                       55
<PAGE>

continuation statements as necessary from time to time (in the Administrative
Agent's and Collateral Agent's discretion) to perfect or continue perfection of
the Liens granted pursuant to the Loan Documents. For purposes of this Article
V, (i) if either S&P or Moody's shall not have in effect an Index Debt Rating
(other than by reason of the circumstances referred to in the last sentence of
this Section 5.01), then such rating agency shall be deemed to have established
an Index Debt Rating below the Security Threshold Rating Level, and (ii) if the
Index Debt Ratings established or deemed to have been established by S&P and
Moody's shall be changed (other than as a result of a change in the rating
system of S&P or Moody's), such change shall be effective as of the date on
which it is first announced by the applicable rating agency. If the rating
system of S&P or Moody's shall change, or if either such rating agency shall
cease to be in the business of rating corporate or subordinated debt obligations
(as applicable), the Borrower and the Lenders shall negotiate in good faith to
amend this Article V to reflect such changed rating system or the unavailability
of ratings from such rating agency and, pending the effectiveness of any such
amendment, the provisions of this Article V shall be construed and determined by
reference to the rating most recently in effect prior to such change or
cessation.

         SECTION 5.02 Collateral Released. If at any time the Index Debt Ratings
established by S&P or Moody's are (or either one of them is) increased to a
level (as established in accordance with the terms of Section 5.01) above the
Security Threshold Rating Level, the Borrower may request the Collateral Agent
in writing, with copies thereof delivered simultaneously to the Administrative
Agent, to release the Liens on and encumbering the Collateral. Promptly after
the Administrative Agent receives such written request from the Borrower,
together with evidence of the applicable Index Debt Ratings, and provided no
Default or Event of Default then exists, the Administrative Agent shall, without
the consent or approval of any other Lender or Creditor (as defined in the
Intercreditor Agreement), at the Borrower's expense, cause the Collateral Agent
to release such Collateral.

         SECTION 5.03 Collateral Reinstated. If at any time following the
release of Collateral as provided in Section 5.02, the Index Debt Ratings are
reduced to a level (as established in accordance with Section 5.01) equal to or
below the Security Threshold Rating Level, the Borrower will, and will cause
each of its Subsidiaries (as applicable) to, at the Borrower's expense, execute
and deliver to the Administrative Agent and/or the Collateral Agent, for the
benefit of the Lenders and/or Creditors (as defined in the Intercreditor
Agreement), on or prior to the date which is thirty (30) Business Days following
the reduction of such Index Debt Ratings to a level equal to or below the
Security Threshold Rating Level, such Security Instruments and other documents,
instruments, agreements and certificates as the Administrative Agent and/or the
Collateral Agent shall deem necessary or appropriate in its or their sole
discretion to create, evidence and perfect the Liens contemplated by Section
5.01.

         SECTION 5.04 Release of Certain Existing Collateral. As soon as
reasonably practicable following the Effective Date, the Liens encumbering the
Mortgaged Property (as defined in the Existing Credit Agreement) and the other
Property of the Borrower and its Subsidiaries described on Schedule 5 of the
Existing Credit Agreement, to the extent granted to secure the Lender
Indebtedness under and as defined in the Existing Credit Agreement and not
securing the Lender Indebtedness as defined herein, shall be released.

                  (g)      any event or condition occurs that results in any
Material Indebtedness becoming due prior to its scheduled maturity or that

both) the holder or holders of any Material Indebtedness or any trustee or agent
on its or their behalf to cause any Material Indebtedness to become due, or to
require the prepayment, repurchase, redemption or defeasance thereof, prior to
its scheduled maturity; provided that this clause (g) shall not apply to secured
Indebtedness that becomes due as a result of the voluntary sale or transfer of
the property or assets securing such Indebtedness;

                  (h)      an involuntary proceeding shall be commenced or an

other relief in respect of the Borrower or any Material Subsidiary or its debts,
or of a substantial part of its assets, under any Federal, state or foreign
bankruptcy, insolvency, receivership or similar law now or hereafter in effect
or (ii) the appointment of a receiver, trustee, custodian, sequestrator,
conservator or similar official for the Borrower or any Material Subsidiary or
for a substantial part of its assets, and, in any such case, such proceeding or
petition shall continue undismissed for 60 days or an order or decree approving
or ordering any of the foregoing shall be entered;

                  (i)      the Borrower or any Material Subsidiary shall (i)

to the institution of, or fail to contest in a timely and appropriate manner,
any proceeding or petition described in clause (h) of this Article VIII, (iii)
apply for or consent to the appointment of a receiver, trustee, custodian,

admitting the material allegations of a petition filed against it in any such
proceeding, (v) make a general assignment for the benefit of creditors or (vi)

they become due;

                  (k)      one or more judgments for the payment of money in an

<PAGE>

Lien on any Collateral, with the priority required hereby or by the
Intercreditor Agreement, except as a result of the sale or other disposition of
the applicable Collateral in a transaction permitted under the Loan Documents;

                  (o)      either any Subsidiary Guaranty, any Security
Agreement, any Pledge Agreement, the Intercreditor Agreement or any other
Security Instrument shall for any reason cease to be in full force and effect
and valid, binding and enforceable in accordance with its terms after its date

writing;

                  (p)      the occurrence of an Event of Default under and as
defined in the Intercreditor Agreement; or

                  (q)      the occurrence of an event of default under the
Indenture, which such event of default shall continue unremedied or is not
waived prior to the expiration of any applicable period of grace or cure under
the Indenture;

then, and in every such event (other than an event with respect to the Borrower
described in clause (h) or (i) of this Article VIII), and at any time thereafter
during the continuance of such event, the Administrative Agent may, and at the
request of the Required Lenders shall, by notice to the Borrower, take either or
both of the following actions, at the same or different times: (i) terminate the
Revolving Commitments, and thereupon the Revolving Commitments shall terminate
immediately, and (ii) declare the Loans then outstanding to be due and payable
in whole (or in part, in which case any principal not so declared to be due and
payable may thereafter be declared to be due and payable), and thereupon the
principal of the Loans so declared to be due and payable, together with accrued
interest thereon and all fees and other obligations of the Borrower accrued
hereunder, shall become due 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 Revolving 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 any kind, all of which are
hereby waived by the Borrower. In addition to the other rights and remedies that
the Lenders may have upon the occurrence of an Event of Default, the Required
Lenders may direct the Administrative Agent and, in accordance with the terms
of, and subject to the necessary consent of the other parties to, the
Intercreditor Agreement, the Collateral Agent, to exercise the rights and
remedies available to the Administrative Agent and the Collateral Agent under
the Security Agreements, the Pledge Agreements and the other Security
Instruments.

                                   ARTICLE IX
                                     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,

                                       68
<PAGE>

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 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.

<PAGE>

                  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 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.

                                  MISCELLANEOUS

         SECTION 10.01 Notices. Except in the case of notices and other
communications expressly permitted to be given by telephone, all notices and
other communications provided for herein shall be in writing and shall be
delivered by hand or overnight courier service, mailed by certified or
registered mail or sent by telecopy, as follows:

                  (a)      if to the Borrower, to it at Trinity Industries,
Inc., 2525 Stemmons Freeway, Dallas, Texas 75207, Attention: Neil Shoop
(Telecopy No.: 214-589-8824);

                  (b)      if to the Administrative Agent, to it at JPMorgan
Chase Bank, 2200 Ross Avenue, 3rd Floor, Dallas, Texas, Texas 75201, Attention:
Michael Lister (Telecopy No.: 214-965-2044), with a copy to JPMorgan Chase Bank,
1111 Fannin, Floor 10, Houston, Texas 77002, Attention: Sheila Fitzwater
(Telecopy No.: 713-216-2228);

                  (c)      if to the Issuing Bank, to it at JPMorgan Chase Bank,
2200 Ross Avenue, 3rd Floor, Dallas, Texas, Texas 75201, Attention: Michael
Lister (Telecopy No.: 214-965-2044), with a copy to JPMorgan Chase Bank, 1111
Fannin, Floor 10, Houston, Texas 77002, Attention: Sheila Fitzwater (Telecopy
No.: 713-216-2228); and

                  (d)      if to any other Lender, to it at its address (or
telecopy number) set forth in its Administrative Questionnaire.

Any party hereto may change its address or telecopy number for notices and other
communications hereunder by notice to the other parties hereto. All notices and
other communications given to any party hereto in accordance with the provisions
of this Agreement shall be deemed to have been given on the date of receipt.

         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.

                                       71
<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 Revolving 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 Revolving 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" 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.

         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, 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

                                       72
<PAGE>

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 Revolving
Credit 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 assert, and hereby waives, any claim against any Indemnitee,
on any theory of liability, for special, 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

                                       73
<PAGE>

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
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 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 Lender's Revolving Commitment, the
aggregate amount of the Revolving Commitments of the assigning 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) 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 (iv) shall not apply to rights in respect of outstanding Competitive
Loans, (v) 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

                                       74
<PAGE>

payable, and (vi) 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
Revolving 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.

                  (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

                                       75
<PAGE>

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 Letter of Credit is outstanding and so long as the Revolving
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 Revolving 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 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
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

                                       77
<PAGE>

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 10.10.

         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
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

                                       78
<PAGE>

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 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

                                       79
<PAGE>

         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 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

                                       80
<PAGE>

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.

         SECTION 10.16 USA Patriot Act Notice. Each Lender hereby notifies the
Borrower that pursuant to the requirements of the USA Patriot Act (Title III of
Pub. L. 107-56 (signed into law October 26, 2001)) (the "Act"), it is required
to obtain, verify and record information that identifies the Borrower, which
information includes the name and address of the Borrower and other information
that will allow such Lender to identify the Borrower in accordance with the Act.

         SECTION 10.17 Lender Indebtedness as Senior Indebtedness. The parties
hereto acknowledge and agree that the Lender Indebtedness is "Senior
Indebtedness" of the Borrower under and as defined in the Indenture.

                  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.

         THIS GUARANTY (this "Guaranty"), dated as of ____________, 200_, is

         WHEREAS, pursuant to an Amended and Restated Credit Agreement, dated as

         WHEREAS, the Guarantor has duly authorized the execution, delivery and
performance of this Guaranty; and

         WHEREAS, it is in the best interests of the Guarantor to execute this

issued from time to time for the account of, the Borrower and its Subsidiaries
by the Lenders and the Issuing Bank, as the case may be, pursuant to the Credit

                               GUARANTY PROVISIONS

         Section 2.01 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 Obligations 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

                                      B-2

<PAGE>

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. Section
362(4), and the operation of Sections 502(b) and 506(b) of the United States
Bankruptcy Code, 11 U.S.C. Section 502(b) and Section 506(b)), and

                  (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 2.02 ACCELERATION OF GUARANTY. The Guarantor agrees that, in
the event that the Obligations have 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
Obligations.

         Section 2.03 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 Obligations 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 Revolving Commitments
shall have terminated and all Letters of Credit shall have terminated or
expired. The Guarantor guarantees that the Obligations 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

                                      B-3

<PAGE>

                           (2)      to exercise any right or remedy against any
         other guarantor of any Obligations 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 Obligations of the Borrower or
any other Loan Party, or any other extension, compromise, or renewal of any
Obligation of the Borrower or any other Loan Party;

                  (d)      any reduction, limitation, impairment or termination
of any Obligations of the Borrower or any other Loan Party for any reason (other
than indefeasible payment in full in cash of the Obligations), 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 Obligations
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 Obligations of the Borrower or any other Loan
Party; or

                  (g)      any other circumstance (other than indefeasible
payment in full in cash of the Obligations) 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 2.04 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 Obligations 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 2.05 WAIVER, ETC. The Guarantor hereby waives promptness,
diligence, notice of acceptance and any other notice with respect to any of the
Obligations 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
Obligations of the Borrower or any other Loan Party, as the case may be.

         Section 2.06 WAIVER OF SUBROGATION. Until the indefeasible payment in
full in cash of all Obligations and the termination or expiration of all
Revolving Commitments and Letters of Credit, the Guarantor hereby irrevocably
waives any claim or other rights which it may now or

                                      B-4

<PAGE>

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 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 Obligations, 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 3.01 REPRESENTATIONS AND WARRANTIES. The Guarantor hereby
represents and warrants unto each Lender Party as set forth in this Article.

         Section 3.02 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 3.03 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 3.04 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

                                      B-5

<PAGE>

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 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 3.05 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 3.06 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 3.07 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 3.08 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.

         Section 4.01 COVENANTS. Until the payment in full in cash of all
Obligations and the termination or expiration of all Revolving Commitments and
Letters of Credit, the Guarantor covenants and agrees that the Guarantor will
perform, comply with, observe and fulfill each of the covenants, agreements and
obligations contained in the Credit Agreement, including without limitation,
Article VI and Article VII of 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.

respective successors, transferees and assigns permitted by Section 10.04 of the
Credit Agreement.

         Section 5.03 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 5.04 ADDRESSES FOR NOTICES TO THE GUARANTOR. All notices and
other communications hereunder to the Guarantor shall be in writing (including

communications shall be effective as provided in Section 10.01 of the Credit
Agreement.

         Section 5.05 NO WAIVER REMEDIES. In addition to, and not in limitation
of, Section 2.03 and Section 2.05, no failure on the part of any Lender Party to
exercise, and no delay in exercising, any right hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise of any right hereunder

deposits (general or special, time or demand, provisional or final) at any time
held and other obligations at any time owing by such Lender Party to or for the
credit or the account of the Guarantor or any of its Subsidiaries against any of

Guaranty held by such Lender, irrespective of whether or not such Lender Party

documentation included in the Collateral to the extent set forth therein to
perform all of its duties and obligations thereunder to the same extent as if

its rights or remedies hereunder shall not release any Debtor from any of its
duties or obligations under such documentation, (c) the Agent shall not have any
obligation under any of such documentation included in the Collateral by reason
of this Agreement, and (d) the Agent shall not be obligated to perform any of
the obligations of any Debtor thereunder or to take any action to collect or

                         REPRESENTATIONS AND WARRANTIES

         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

                                      G-2

<PAGE>

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. 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. It 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. It 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 such
Debtor's 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) does
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 and performed in full and the Intercreditor Agreement
terminates:

         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 the Agent's 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

                                      G-4

<PAGE>

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.

         Section 4.03 Third Parties in Possession of Collateral. It 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 such Debtor's 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 the Agent as secured party and notifying such third Person's secured
lenders of its interest in such Collateral before such 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 the Agent's 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 the Agent's 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
                               RIGHTS OF THE AGENT

         Section 5.01 POWER OF ATTORNEY. EACH DEBTOR HEREBY IRREVOCABLY
CONSTITUTES AND APPOINTS THE AGENT AND ANY OFFICER OR AGENT THEREOF, WITH FULL
POWER OF 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,

AND, WITHOUT LIMITING THE

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

         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 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 such Debtor and the
Agent. Each Debtor agrees that the Agent shall not be obligated to give more
than ten (10) days prior written

                                      G-7

<PAGE>

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 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.

         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 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

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

the parties hereto and the number of Creditors required by the Intercreditor

         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.

         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

Transaction Documents;

                  (b)      any change in the time, manner, or place of payment

                                PLEDGE AGREEMENT

         THIS PLEDGE AGREEMENT (this "Agreement") is made as of ______________,
200__, 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 March 10, 2004 (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,
and (3) all cash, securities, dividends and other property at any time and from
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 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).

                  (b)      Without limiting the foregoing, all costs incurred by
Secured Party to obtain, preserve, perfect and enforce this Agreement, the other
Transaction Documents, and the pledge and

preserve, collect and enforce the Collateral, including, without limitation,
taxes, assessments, attorneys' fees and legal expenses, and expenses of sale.

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. Section 101
et seq. whether or not a claim is allowed for the same in any such proceeding.

         3.       COVENANTS, REPRESENTATIONS AND WARRANTIES.

                  (a)      Representations and Warranties.

                           (1)      Representations and Warranties Concerning

         Pledgor of the security interest granted hereby or for the execution,
         delivery or performance of this Agreement by Pledgor, (ii) for the
         perfection or maintenance of the pledge, assignment and security
         interest created hereby (including the first priority nature of such
         pledge, assignment and security interest), or (iii) for the exercise by
         Secured Party of the rights provided for in this Agreement or in the
         Intercreditor Agreement, or the remedies in respect of the Collateral

         default) under any debt or other contractual obligation of Pledgor; (F)

         arbitration or other proceeding pending or threatened against or

         covering the Collateral, or any part thereof, has been made, and no
         pledge or security interest, other than the one herein created, has

                  (b)      Covenants.

                           (1)      Affirmative Covenants. Pledgor covenants and

         Party with any information or writings which Secured Party or any
         Creditor may reasonably request concerning the Collateral; (D) to allow

         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

         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 hereunder or in connection with the
         enforcement hereof.

                           (2)      Negative Covenants. Except as otherwise
         provided in the Revolver 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 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 Agreement, the
terms and provisions of Article VI and/or Article VII of the Revolver 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

                                      H-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 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.

                  (e)      Power of Attorney. PLEDGOR HEREBY IRREVOCABLY GRANTS
TO SECURED PARTY PLEDGOR'S PROXY (EXERCISABLE FROM AND AFTER THE OCCURRENCE AND
DURING THE 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
PARTY'S RIGHTS HEREUNDER. THE PROXY AND POWER OF ATTORNEY HEREIN GRANTED, AND
EACH STOCK POWER AND SIMILAR POWER NOW OR HEREAFTER GRANTED (INCLUDING ANY
EVIDENCED BY A SEPARATE WRITING) ARE COUPLED WITH AN INTEREST AND ARE
IRREVOCABLE PRIOR TO FINAL PAYMENT IN FULL OF THE OBLIGATIONS.

<PAGE>

         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

                                      H-5

<PAGE>

         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

                                      H-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.

                                      H-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)      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.

                                    [FORM OF]
                         INCREASED COMMITMENT AGREEMENT

institutions which is a signatory hereto (individually a "Supplementing Lender"
and collectively the "Supplementing Lenders"), and JPMorgan Chase Bank, as
Administrative Agent for itself and the Lenders (in such capacity, together with
its successors in such capacity, the "Administrative Agent"), and is made with
reference to that certain Amended and Restated Credit Agreement dated as of

                           GRAIN PROCUREMENT AGREEMENT

      THIS GRAIN PROCUREMENT AGREEMENT, (the "Agreement") is made and entered
into this _____ day of _________, 2004, by and between GRANITE FALLS COMMUNITY
ETHANOL PLANT, LLC ("GFCEP") and FARMERS COOPERATIVE ELEVATOR CO. ("FCE").

      WHEREAS, GFCEP intends to construct, own, and operate a dry mill ethanol
and byproduct manufacturing plant and related facilities (the "Facilities") on
the Premises (defined below);

      WHEREAS, the acquisition of a steady and reliable supply of corn is
integral to the use and operation of the Facilities;

      WHEREAS, in order to guaranty the use and operation of the Facilities, the
parties are entering into this Agreement whereby FCE will provide a steady and
reliable supply of corn to GFCEP for use in the operation of the Facilities
under the terms and conditions hereinafter described.

       NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants herein contained, it is hereby agreed as follows:

                            TITLE I: PRIOR AGREEMENTS

1.1.01:  PRIOR AGREEMENTS SUPERSEDED

      The parties hereby agree and acknowledge that they previously entered into
one or more agreements relating to the operation of GFCEP, including, but not
limited to a Declaration of Restrictions and Covenants made by the Granite Falls
Community Ethanol Plant, LLC; a Corn Storage and Delivery Agreement, and a
Pre-Closing Memorandum. All such agreements are superseded by the terms of this
Grain Procurement Agreement and such prior agreements are hereby revoked;
provided, however, that all subscription agreements to purchase units in GFCEP
shall remain in full force and effect.

                               TITLE II: FACILITY

                                    ARTICLE I
                                    PREMISES

2.1.01: LAND

      The Facilities (also described herein as "plant") will be constructed on
the premises (real estate) legally described as being east of the City of
Granite Falls, County of Chippewa, State of Minnesota, legally described as:

             SEE EXHIBIT "A" ATTACHED HERETO AND MADE A PART HEREOF

                           TITLE III: CORN PROCUREMENT

                                    ARTICLE I
                                PROVISION OF CORN

3.1.01: FCE'S PROVISION OF CORN

      (a) FCE shall have the exclusive right and responsibility to provide GFCEP
its full daily requirements of No. 2 yellow corn, 15% moisture content, meeting
the specifications of this Agreement (the "Corn") during the term hereof and
under the conditions herein set forth. This right and responsibility shall
include the plant as originally constructed and any and all alterations,
modifications or expansions thereof.

      (b) Purchases. The parties acknowledge and agree that GFCEP shall purchase
all of its corn requirements from FCE and shall place all actual orders for
purchase of corn to be delivered to the facility with FCE. At all times, FCE,
either through its own management or through lawful contracts entered into with
third parties, shall maintain
<PAGE>
or cause to be maintained such licenses and/or authorities as may be required to
lawfully engage in the purchase and sale of corn.

      (c) Risk Management. Notwithstanding the foregoing, GFCEP acknowledges
that it shall separately retain appropriate risk management services for
evaluating corn pricing and purchases and/or for making trades for price
protection and future delivery such as options, future contracts and the like.

      (d) Delivery Estimates. GFCEP agrees to provide to FCE an estimate on or
before the first day of each calendar quarter with respect to its required
deliveries of corn for the following calendar quarter. The parties expressly
understand that GFCEP's notice shall be a good faith estimate and that the
parties anticipate reasonable variations between delivery forecast and actual
delivery requirements. For purposes of this Agreement the phrase "reasonable
variations" shall mean a variation of no more than 10% between the delivery
forecast and actual delivery requirements. To that end, GFCEP shall also report
to FCE on or before the first business day of each month its estimated delivery
requirement of corn for the following month.

      (e) FCE shall maintain a minimum of four days supply of corn in storage at
GFCEP at all times.

3.1.02: CORN QUALITY

      (a) Corn Quality. Corn delivered under this Agreement shall: (i) be No. 2
shelled yellow corn, having no more than a 15% moisture content; (ii) be graded
in accordance with State and Federal laws and in accordance with any reasonable
standards set by GFCEP; (iii) be merchantable and not be adulterated; (iv) meet
such additional specifications and standards as the parties may establish from
time to time by mutual agreement, including without limitation standards and
specifications related to test weight (determined with reference to moisture
content), foreign material and mycotoxin and other toxin levels.

      It is understood and agreed that corn over 15% moisture content will be
delivered and/or corn with certain of the discount elements described in
paragraph 3.1.02(b) may be delivered and such is acceptable to GFCEP, subject to
the pricing discount(s) and other terms described in said paragraph 3.1.02(b).

      It is understood and agreed that the parties intend that the corn quality
provisions of this Agreement that pertain to daily averages shall be construed
so that FCE is able to compete with other corn merchants in the surrounding area
and correspondingly so that GFCEP is treated fairly. The daily average on
quality factors shall not be abused by reasons such as bringing specific quality
loads at certain times of the day to maximize the ranges allowed in the average
window allowance(s). This will be monitored on a daily basis and if there is any
material violation, GFCEP will not be required to and shall not allow any loads
for that day to be applied to the daily averages as described in this Agreement.

      (b) Corn Not Meeting Quality Requirements. GFCEP may, at its option: (i)
reject any corn delivered by FCE that does not meet these specifications
described herein or (ii) accept corn delivered by FCE that does not meet these
specifications on the following discounted pricing terms:

MUSTY/SOUR - 5 cents per bu. If not rejected.

The parties agree that the quality requirements (and corresponding right to
reject corn) and discount schedule shall be applied as follows:

      1.    Moisture: There will be no discount on a load of corn until it is
            above 15.0%, and then a discount and right to reject as described in
            the discount schedule. The discount schedule and right to reject
            regarding moisture shall be determined on a load by load basis.

      2.    Test Weight: All loads with a test weight of 50 lbs. and above shall
            be averaged on a daily average basis, with the discount schedule
            applied on that daily average. All loads of test weights below 50
            lbs. shall be handled on a load by load basis, subject to the right
            of rejection and with the discount schedule (if such corn is
            accepted) being applied on a load by load basis.

      3.    Damage (Regular and/or Heat): All loads between 0% and 10% damage
            shall be averaged on a daily average basis, with the discount
            schedule applied on that daily average. Any loads of corn with more
            than 10% damage shall be handled on a load by load basis, with right
            to reject and in applying the discount schedule.

      4.    Foreign Material: Loads with 0% to 6% foreign material shall be
            averaged on a daily average basis, with the discount schedule
            applied on that daily average. Loads with more than 6% foreign
            material shall be handled on a load by load basis, with right to
            reject and in applying the discount schedule. Toxins. Any load of
            corn that tests positive for microtoxins or other toxins will be
            rejected. However, it is agreed that FCE is responsible only to use
            "black light" testing to determine the existence of such toxins. If
            GFCEP desires additional testing, it shall give written notice to
            FCE and

            GFCEP shall pay all costs of such additional testing.

This discount schedule is subject to change as market conditions dictate
providing both FCE and GFCEP mutually agree to any change in writing.

      (c) Limitation on Quality Requirements. Notwithstanding the foregoing
provisions of this Section 3.1.02, FCE shall not be required to provide Corn
under this Agreement with qualities and characteristics exceeding the average
qualities of Corn produced during the preceding corn production year ending on
August 31 of such year in the specific area surrounding the Plant defined as
within a twenty (20) mile radius of the plant. If such average qualities of corn
produced within a 20 mile radius of the plant are unacceptable to GFCEP, as
reasonably determined by GFCEP, then FCE shall have the right to procure corn
from other geographic areas until such time as the average qualities of corn
within the 20 mile radius of the plant are reasonably acceptable to GFCEP. If
corn is procured

                                      -3-
<PAGE>
from other geographic areas pursuant to the terms of this paragraph, the Market
Price shall be the purchase price, plus shipping costs. In addition, GFCEP shall
pay FCE the per bushel procurement fee.

      (d) Determination of a Bushel of Corn. For purposes of FCE's delivery
obligations hereunder, a "bushel of Corn" or "bushel" is to be equivalent to a
bushel of No. 2 shelled yellow corn at 15% moisture and a weight of 56 pounds
per bushel. The moisture content and test weights of the Corn delivered to GFCEP
under this Agreement shall be determined and discounts on price, if any,
applied, as described in Paragraph 3.1.02 (b).

3.1.03: LICENSING

      FCE shall obtain Corn to be provided to GFCEP under this Agreement under
FCE's own grain dealer's license. GFCEP shall obtain and maintain a grain
dealer's license. FCE shall also obtain any and all licenses or permits
necessary for FCE to meet its obligations under this Agreement.

3.1.04: PAYMENTS TO CORN SUPPLIERS

      FCE will account for the Corn provided by, and settle with, all third
parties providing Corn to the Plant.

                                   ARTICLE II
                            TERM OF CORN PROCUREMENT

3.2.01: COMMENCEMENT

      The terms of this Agreement shall become effective on the first date that
the facility needs corn for testing, startup or operations. GFCEP shall notify
FCE ten (10) days in advance of when corn is first needed.

3.2.02: TERM OF AGREEMENT

      The term of this Agreement shall begin on the first day corn is requested
by GFCEP as stated in paragraph 3.2.01 and shall continue for a term of twelve
(12) years thereafter. Suspensions of operations for any reason, such as
repairs, modifications, expansions or damage to the facility shall not terminate
this Agreement - provided the plant thereafter resumes operations.

                                   ARTICLE III
                              CORN PROCUREMENT FEE

3.3.01: PROCUREMENT FEE

      For the first four (4) years of the Corn Procurement Term, GFCEP will pay
FCE a Corn procurement and delivery fee of $0.05 per bushel of Corn delivered
pursuant to Title 3 of this Agreement (the "Procurement Fee"). Beginning on the
fourth (4th) year anniversary of the Corn Procurement Term, the Procurement Fee
shall be increased to 5.5 cents per bushel of Corn delivered. Beginning on the
eighth (8th) year anniversary of the Corn Procurement Term, the Procurement Fee
shall be increased to 6 cents per bushel of Corn delivered.

3.3.02: CORN FOR GFCEP

      For any Corn required by GFCEP and provided by FCE pursuant to this
Agreement, GFCEP shall pay FCE the Market Price as determined in Title III,
Article IV (or, if applicable, Title III, Article I, paragraph 3.1.02(c)), plus
the Procurement Fee and storage fees provided for under this Agreement.

3.3.03: HEDGING ASSISTANCE

      FCE shall assist GFCEP, or GFCEP's designated agent, in GFCEP's forward
purchases of Corn to "lock in" the costs thereof whenever GFCEP determines such
risk positions are prudent. The determination of GFCEP need not be separately
evidenced in writing so long as GFCEP communicates to FCE its decision to make
forward

                                      -4-
<PAGE>
purchases. GFCEP shall pay the purchase price for such forward purchases plus
the Procurement fee and, if applicable, storage fees.

      GFCEP shall pay the purchase price when the corn is purchased or when
invoiced, whichever occurs first. The Procurement fee shall be due when the corn
is delivered to the plant and the Procurement fee invoiced as provided by Title
III, Article IV, paragraph 3.4.01. Any storage fees shall be paid as agreed on a
case by case basis by the parties, or if no such agreement occurs, as is
customary and standard or as otherwise provided by this Agreement.

                                   ARTICLE IV
                              INVOICING AND PAYMENT

3.4.01 GFCEP shall pay FCE for the corn as delivered to the GFCEP facilities and
the corresponding Procurement Fee for said corn every Wednesday at 10:00 a.m.
central time for deliveries accrued through the close of business on Monday. If
any Wednesday falls on a national holiday, payment shall occur 10:00 a.m. the
next day.

3.4.02 The Market Price per bushel is the daily posted board price at the
Minnesota Falls branch of the FCE as of 10:00 a.m. the next trading day after
the corn is delivered to the GFCEP facility. The discounts, if any, shall be
determined pursuant to paragraph 3.1.02(b).

                                    ARTICLE V
                           LOCATION OF FCE'S DELIVERY

3.5.01 FCE shall deliver all Corn to GFCEP, and risk of loss shall pass to
GFCEP, at the Facilities.

3.5.02 All responsibility for and all unloading will be performed by GFCEP at
the sole and exclusive cost of GFCEP.

3.5.03 The GFCEP shall provide space rent free at its facility for no more than
two (2) employees of the FCE, so that said employees may coordinate the purchase
and delivery of corn to the GFCEP facilities. Said employee shall not be
responsible for and shall not be involved in the unloading or handling of said
corn when it arrives at the facility site. It is intended that said FCE
employees shall remain in "office" because of GFCEP's liability concerns.

      Said FCE employees at GFCEP shall be responsible to weigh and grade corn
as delivered to the GFCEP facility. FCE employees will take and provide the
required corn samples so that said weighing and grading can properly occur.
GFCEP employees shall, from time to time, spot check the weighing and grading
conducted by FCE employees.

3.5.04 Any disputes over grade discrepancies will be settled by the Minnesota
Grain Inspection Department.

3.5.05 The grain purchased or owned by GFCEP which is held pursuant to warehouse
receipt or priced later shall be physically stored in FCE's facilities.

3.5.06 The facility as constructed by GFCEP shall have a minimum of 470,000
bushels of corn storage and if the plant is expanded, then storage on the plant
site shall proportionately increase so the on site storage at the plant has at
least enough capacity to hold ten (10) days of corn for operation of the plant.

3.5.07 The design of the GFCEP grain receiving, handling and storage facilities
shall be subject to the review of FCE before such are constructed. Any expansion
or material modification of such grain receiving, handling and storage
facilities of GFCEP shall likewise be subject to review by FCE before any such
expansion or material modification occurs. GFCEP shall give due consideration to
comments or recommendations made by FCE following its review. However, GFCEP
shall not be bound to accept such comments or recommendations.

                                   ARTICLE VI
                          DEFAULT, WAIVER, AND REMEDIES

3.6.01: DEFAULT, NOTICE, AND CURE

      (a) Except as provided in Section 3.6.01(b), if either party shall fail to
perform any of the covenants or obligations imposed upon it by this Agreement
(except such failure as shall be excused under Title IV, Article III), the other
party shall notify the party in default in writing of the alleged default and if
the party in default shall not cure said default within fifteen (15) days from
and after receiving such notice (the "Cure Period"), then notwithstanding any
other provision of this Agreement, the complaining party shall have the remedies
set forth in Section 3.6.03.

      (b) If GFCEP fails to make payment for Corn delivered by FCE and accepted
by GFCEP under the terms of this Agreement, the provisions of Section 3.6.01(a)
shall apply; however, the Cure Period shall be three (3) days from and after
GFCEP's receipt of notice of GCFEP's default from FCE.

3.6.02: WAIVER

      Waiver by either party of any breach of the terms and conditions herein
contained shall not be construed as a waiver of any subsequent breach of the
same or any other provision of this Agreement.

3.6.03: REMEDIES

      (a) GFCEP's Remedies. If FCE fails to deliver Corn as required by this
Agreement, or if GFCEP reasonably in good faith believes that FCE will fail to
deliver corn as required by this agreement, GFCEP may: (i) in good faith and
without unreasonable delay, make any reasonable purchase of Corn in substitution
of the quantity due from FCE, (ii) recover from FCE as damages the difference
between the cost of cover under (i) and the Market Price (or the average Board
price at the comparable location(s) established by the Amendment to this
Agreement, if Market Price cannot be determined), plus the Procurement Fee,
together with any incidental or consequential damages, but less expenses saved
in consequence of FCE's breach, (iii) seek and receive injunctive relief or a
decree of specific performance, (iv) credit the amount of damages FCE has become
obligated to pay GFCEP, as determined by arbitration or if arbitration fails to
occur as required hereby, a court of competent jurisdiction, to GFCEP and set
off such amount against any amounts owed by GFCEP to FCE.

      (b) FCE's Remedies. If GFCEP fails to make any payment for Corn delivered
by FCE and accepted by GFCEP under the terms of this Agreement, FCE may recover
the payments from GFCEP. FCE may withhold future scheduled deliveries only if
GFCEP fails to pay FCE the payments owed FCE as provided by this Agreement
within three (3) business days after GFCEP's receipt of FCE's written demand for
payment. FCE shall also have the right to specifically enforce the terms of this
Agreement, including, but not limited to, the obligation of GFCEP to purchase
all of the corn needed to operate the plant from FCE.

      (c) No right, power or remedy conferred by this Agreement shall be
exclusive of any other right, power or remedy now or hereafter available at law,
in equity, by statute or otherwise. In case of material reoccurring defaults,
the non-defaulting party shall be entitled to an immediate remedy available at
law, in equity, by statute or otherwise, not withstanding the notice and cure
provisions of this Article 6.

                          TITLE IV: GENERAL PROVISIONS

                                   WARRANTIES

4.1.01: OWNERSHIP AND QUALITY OF CORN

      FCE warrants to GFCEP that FCE owns all of the Corn delivered to GFCEP
under this Agreement and that such Corn shall be free and clear of any security
interest, lien, penalty, charge, or encumbrance, governmental or

                                      -6-
<PAGE>
otherwise. If FCE has granted a security interest in any of the Corn delivered,
FCE shall inform GFCEP in writing, at or before delivery of the Corn, of any
such secured party's name and address. GFCEP shall have the right, but not the
obligation, to name the secured party as co-payee with FCE on any payment for
the Corn and to deliver such payment to the secured party.

4.1.02: NO EXPRESS OR IMPLIED WARRANTIES

      Neither party shall be liable for any representation or warranty of any
kind, express or implied, not expressly set forth in this Agreement.

                                   ARTICLE II
                               DISPUTE RESOLUTION

4.2.01: ALTERNATIVE DISPUTE RESOLUTION

      If a dispute, controversy, or claim arises out of or relates to this
Agreement, or the alleged breach thereof, including any claim or allegation of
fraud or misrepresentation, and if said dispute cannot be settled through direct
discussions, the parties agree to first endeavor to settle the dispute in an
amicable manner by mediation with an independent mediator selected by mutual
agreement of the parties. If the parties are unable to agree on a mediator,
mediation shall be administered by the American Arbitration Association under
its Commercial Mediation Rules. If the matter has not been resolved pursuant to
mediation within thirty (30) days of the commencement of such mediation (which
period may be extended by mutual agreement in writing), then any unresolved
dispute, controversy, or claim arising out of or relating to this Agreement, or
the breach thereof, shall be settled by arbitration administered by the American
Arbitration Association in accordance with its Commercial Arbitration Rules (the
"Commercial Arbitration Rules"), and judgment upon the award rendered by the
arbitrators may be entered in the Minnesota District Court in Yellow Medicine or
Chippewa County, Minnesota, or the highest state court having jurisdiction. The
arbitration shall be conducted in Yellow Medicine County, Minnesota by a panel
of three neutral arbitrators appointed pursuant to the Commercial Arbitration
Rules.. The arbitrators shall permit each party to conduct limited relevant
discovery. The arbitrators shall award damages measured by the prevailing
party's actual damages, and may not, in any event, make any ruling, finding or
award that does not conform to the terms and conditions of this Agreement. The
provisions of this Agreement shall be a complete bar and defense to any suit,
action or proceeding instituted in any court or administrative tribunal with
respect to any controversy or dispute under this Agreement which is arbitrable.

4.2.02: ATTORNEY'S FEES AND COSTS

      The parties agree that the arbitration panel shall award to the prevailing
party in any dispute resolution proceedings related to this Agreement, from the
other party, the amount of the prevailing party's costs, expenses, and
attorneys' fees as the arbitrators deem fair and equitable.

                                   ARTICLE III
                                  FORCE MAJEURE

4.3.01: RELIEF FROM TRANSFERING CORN

      In the event of either party being rendered reasonably unable by Force
Majeure to perform any of its obligations in receiving or delivering Corn
hereunder, the obligations of such party shall be suspended, to the extent it is
unable, in whole or in part, to receive or deliver Corn by reason of Force
Majeure, during the continuance of any inability so caused and the cause of such
inability shall, so far as possible, be remedied with reasonable diligence.
Inability may include a storm event that does not allow management of GFCEP to
execute documents and otherwise perform wire transfers or payment as required by
this Agreement or which does not permit FCE to perform as required by this
Agreement. However, the party not subject to the force majeure event may, during
such period, accept performance from the other party or a third party as it may
reasonably determine under the circumstances.
