of such Revolving Lender’s Applicable Percentage of the outstanding principal
amount of the applicable Loan with respect to which Settlement is requested to
the Administrative Agent, to such account of the Administrative Agent as the
Administrative Agent may designate, not later than 2:00 p.m., Dallas, Texas
time, on such Settlement Date. Settlements may occur during the existence of a
Default and whether or not the applicable conditions precedent set forth in
Section 4.02 have then been satisfied. Such amounts transferred to the
Administrative Agent shall be applied against the amounts of the Swingline
Lender’s Swingline Loans and, together with Swingline Lender’s Applicable
Percentage of such Swingline Loan, shall constitute Revolving Loans of such
Revolving Lenders, respectively. If any such amount is not transferred to the
Administrative Agent by any Revolving Lender on such Settlement Date, the
Swingline Lender shall be entitled to recover from such Lender on demand such
amount, together with interest thereon, as specified in Section 2.07.

SECTION 2.06. Letters of Credit. (a) General. Subject to the terms and
conditions set forth herein, the Borrower Representative may request the
issuance of Letters of Credit for its own account or for the account of another
Loan Party as the applicant thereof for the support of its or its Subsidiaries’
obligations, in a form reasonably acceptable to the Administrative Agent and the
Issuing Bank, at any time and from time to time during the Availability Period.
In the event of any inconsistency between the terms and conditions of this
Agreement and the terms and conditions of any form of letter of credit
application or other agreement submitted by the Borrowers to, or entered into by
the Borrowers with, the Issuing Bank relating to any Letter of Credit, the terms
and conditions of this Agreement shall

30

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

control. Each Borrower unconditionally and irrevocably agrees that, in
connection with any Letter of Credit issued for the support of any Subsidiary’s
obligations as provided in the first sentence of this paragraph, such Borrower
will be fully responsible for the reimbursement of LC Disbursements in
accordance with the terms hereof, the payment of interest thereon and the
payment of fees due under Section 2.12(b) to the same extent as if it were the
sole account party in respect of such Letter of Credit (such Borrower hereby
irrevocably waiving any defenses that might otherwise be available to it as a
guarantor or surety of the obligations of such Subsidiary that is an account
party in respect of any such Letter of Credit). All Existing Letters of Credit
shall be deemed to have been issued pursuant hereto, and from and after the
Effective Date shall be subject to and governed by the terms and conditions
hereof.

(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 Representative shall
deliver by hand or facsimile (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 (prior to 9:00 am, Dallas, Texas time, at
least two Business Days prior to 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), 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 applicable 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 Borrowers 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 $20,000,000 and
(ii) the Aggregate Revolving Exposures shall not exceed the sum of (A) the
lesser of (1) the aggregate Revolving Commitments and (2) the Borrowing Base,
minus (B) without duplication, Reserves.

(c)    Expiration Date. Each Letter of Credit shall expire (or be subject to
termination by notice from the Issuing Bank to the beneficiary thereof) at or
prior to the close of business on the earlier of (i) the date one year after the
date of the issuance of such Letter of Credit (or, in the case of any renewal or
extension thereof, including, without limitation, any automatic renewal
provision, one year after such renewal or extension) and (ii) the date that is
five Business Days prior to the Maturity Date.

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

(e)    Reimbursement. If the Issuing Bank shall make any LC Disbursement in
respect of a Letter of Credit, the Borrowers shall reimburse such LC
Disbursement by paying to the Administrative Agent an amount equal to such LC
Disbursement (i) not later than 11:00 a.m., Dallas, Texas time, on the date that
such LC Disbursement is made, if the Borrower Representative shall have received
notice of such LC Disbursement prior to 9:00 a.m., Dallas, Texas time, on such
date, or, (ii) if such notice has not been received by the Borrower
Representative prior to such time on such date, then not later than 11:00 a.m.,
Dallas, Texas time, on (A) the Business Day that the Borrower Representative
receives such notice, if such notice is received prior to 9:00 a.m., Dallas,
Texas time, on the day of receipt, or (B) the Business Day immediately following
the day that the Borrower Representative receives such notice, if such notice is

31

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

not received prior to such time on the day of receipt; provided that the
Borrowers shall, subject to the conditions to borrowing set forth herein, be
deemed to have requested, and the Borrowers do hereby request under such
circumstances, that such payment be financed with a CBFR Revolving Borrowing in
an equivalent amount and, to the extent so financed, the Borrowers’ obligation
to make such payment shall be discharged and replaced by the resulting CBFR
Revolving Borrowing. If the Borrowers fail to make such payment when due, the
Administrative Agent shall notify each Revolving Lender of the applicable LC
Disbursement, the payment then due from the Borrowers in respect thereof and
such Lender’s Applicable Percentage thereof. Promptly following receipt of such
notice, each Revolving Lender shall pay to the Administrative Agent its
Applicable Percentage of the payment then due from the Borrowers, in the same
manner as provided in Section 2.07 with respect to Loans made by such Lender
(and Section 2.07 shall apply, mutatis mutandis, to the payment obligations of
the Revolving Lenders), and the Administrative Agent shall promptly pay to the
Issuing Bank the amounts so received by it from the Revolving Lenders. Promptly
following receipt by the Administrative Agent of any payment from the Borrowers
pursuant to this paragraph, the Administrative Agent shall distribute such
payment to the Issuing Bank or, to the extent that Revolving Lenders have made
payments pursuant to this paragraph to reimburse the Issuing Bank, then to such
Lenders and the Issuing Bank as their interests may appear. Any payment made by
a Revolving Lender pursuant to this paragraph to reimburse the Issuing Bank for
any LC Disbursement (other than the funding of CBFR Revolving Loans as
contemplated above) shall not constitute a Loan and shall not relieve the
Borrowers of their obligation to reimburse such LC Disbursement.

(f)    Obligations Absolute. The Borrowers’ joint and several obligation to
reimburse LC Disbursements as provided in paragraph (e) of this Section 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 or herein,
(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) any 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, constitute a legal or equitable
discharge of, or provide a right of setoff against, the Borrowers’ obligations
hereunder. None of the Administrative Agent, the Revolving Lenders, the Issuing
Bank or any of their Related Parties, shall have any liability or responsibility
by reason of or in connection with the issuance or transfer of any Letter of
Credit or any payment or failure to make any payment thereunder (irrespective of
any of the circumstances referred to in the preceding sentence), or any error,
omission, interruption, loss or delay in transmission or delivery of any draft,
notice or other communication under or relating to any Letter of Credit
(including any document required to make a drawing thereunder), any error in
interpretation of technical terms or any consequence arising from causes beyond
the control of the Issuing Bank; provided that the foregoing shall not be
construed to excuse the Issuing Bank from liability to the Borrowers to the
extent of any direct damages (as opposed to special, indirect, consequential or
punitive damages, claims in respect of which are hereby waived by the Borrowers
to the extent permitted by applicable law) suffered by any 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 wilful 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 applicable Borrower by telephone (confirmed by
facsimile) 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 Borrowers of their obligation
to reimburse the Issuing Bank and the Revolving Lenders with respect to any such
LC Disbursement.

32

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

(h)    Interim Interest. If the Issuing Bank shall make any LC Disbursement,
then, unless the Borrowers 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 Borrowers reimburse such LC Disbursement, at
the rate per annum then applicable to CBFR Revolving Loans and such interest
shall be payable on the date when such reimbursement is due; provided that, if
the Borrowers fail to reimburse such LC Disbursement when due pursuant to
paragraph (e) of this Section, then Section 2.13(d) shall apply. Interest
accrued pursuant to this paragraph shall be for the account of the Issuing Bank,
except that interest accrued on and after the date of payment by any Revolving
Lender pursuant to paragraph (e) of this Section 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 Representative, the Administrative
Agent, the replaced Issuing Bank and the successor Issuing Bank. The
Administrative Agent shall notify the Revolving Lenders of any such replacement
of the Issuing Bank. At the time any such replacement shall become effective,
the Borrowers shall pay all unpaid fees accrued for the account of the replaced
Issuing Bank pursuant to Section 2.12(b). From and after the effective date of
any such replacement, (i) the successor Issuing Bank shall have all the rights
and obligations of the Issuing Bank under this Agreement with respect to Letters
of Credit to be issued thereafter and (ii) references herein to the term
“Issuing Bank” shall be deemed to refer to such successor or to any previous
Issuing Bank, or to such successor and all previous Issuing Banks, as the
context shall require. After the replacement of an Issuing Bank hereunder, the
replaced Issuing Bank shall remain a party hereto and shall continue to have all
the rights and obligations of an Issuing Bank under this Agreement with respect
to Letters of Credit then outstanding and issued by it prior to such
replacement, but shall not be required to issue additional Letters of Credit.

(j)    Cash Collateralization. If any Event of Default shall occur and be
continuing, on the Business Day that the Borrower Representative receives notice
from the Administrative Agent or the Required Lenders (or, if the maturity of
the Loans has been accelerated, Revolving Lenders with LC Exposure representing
greater than 50% of the aggregate LC Exposure) demanding the deposit of cash
collateral pursuant to this paragraph, the Borrowers shall deposit in an account
with the Administrative Agent, in the name of the Administrative Agent and for
the benefit of the Revolving Lenders (the “LC Collateral Account”), an amount in
cash equal to 105% of the amount of the LC Exposure as of such date plus 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 any Borrower described in
clause (h) or (i) of Article VII. Such deposit shall be held by the
Administrative Agent as collateral for the payment and performance of the
Secured Obligations. The Administrative Agent shall have exclusive dominion and
control, including the exclusive right of withdrawal, over the LC Collateral
Account and the Borrowers hereby grant the Administrative Agent a security
interest in the LC Collateral 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 Borrowers’ risk and
expense, such deposits shall not bear interest. Interest or profits, if any, on
such investments shall accumulate in the LC Collateral Account. Moneys in the LC
Collateral 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 Borrowers for the LC Exposure at such time or,
if the maturity of the Loans has been accelerated (but subject to the consent of
Revolving Lenders with LC Exposure representing greater than 50% of the
aggregate LC Exposure), be applied to satisfy other Secured Obligations. If the
Borrowers are 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 Borrowers within three (3)
Business Days after all such Events of Default have been cured or waived as
confirmed in writing by the Administrative Agent.

(k)    LC Exposure Determination. For all purposes of this Agreement, the amount
of a Letter of Credit that, by its terms or the terms of any document related
thereto, provides for one or more automatic increases in the stated amount
thereof shall be deemed to be the maximum stated amount of such Letter of Credit
after giving effect to all such increases, whether or not such maximum stated
amount is in effect at the time of determination.

SECTION 2.07. Funding of Borrowings. (a) Each Lender shall make each Loan to be
made by such Lender

33

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

hereunder on the proposed date thereof by wire transfer of immediately available
funds by 1:00 p.m., Dallas, Texas time, to the account of the Administrative
Agent most recently designated by it for such purpose by notice to the Lenders
in an amount equal to such Lender’s Applicable Percentage. The Administrative
Agent will make such Loans available to the Borrower Representative by promptly
crediting the amounts so received, in like funds, to the deposit accounts
identified in the applicable Borrowing Request; provided that CBFR Revolving
Loans made to finance the reimbursement of (i) an LC Disbursement as provided in
Section 2.06(e) shall be remitted by the Administrative Agent to the Issuing
Bank and (ii) a Protective Advance shall be retained by the Administrative
Agent.

(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 and may, in
reliance upon such assumption, make available to the applicable 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 Borrowers 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
applicable Borrower to but excluding the date of payment to the Administrative
Agent, at (i) in the case of such Lender, 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 or (ii) in the case of the
Borrowers, the interest rate applicable to CBFR Loans. If such Lender pays such
amount to the Administrative Agent, then such amount shall constitute such
Lender’s Loan included in such Borrowing.

SECTION 2.08. Interest Elections. (a) Each Revolving Borrowing initially shall
be of the Type specified in the applicable Borrowing Request and, in the case of
a Eurodollar Revolving Borrowing, shall have an initial Interest Period as
specified in such Borrowing Request. Thereafter, the Borrower Representative 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. The Borrower Representative 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 shall not apply
to Swingline Borrowings or Protective Advances, which may not be converted or
continued.

(b)    To make an election pursuant to this Section, the Borrower Representative
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 Borrowers
were requesting a Revolving Borrowing of the Type resulting from such election
to be made on the effective date of such election. Each such telephonic Interest
Election Request shall be irrevocable and shall be confirmed promptly by hand
delivery or facsimile to the Administrative Agent of a written Interest Election
Request in a form approved by the Administrative Agent and signed by the
Borrower Representative.

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

(i)    the name of the applicable Borrower and 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 a CBFR 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”.

34

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

If any such Interest Election Request requests a Eurodollar Borrowing but does
not specify an Interest Period, then the Borrowers 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 Lender of the details thereof and of such
Lender’s portion of each resulting Borrowing.

(e)    If the Borrower Representative 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 a CBFR Borrowing. Notwithstanding any contrary provision hereof, if
a Default has occurred and is continuing and the Administrative Agent, at the
request of the Required Lenders, so notifies the Borrower Representative, then,
so long as a 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 a CBFR Borrowing at the end of the
Interest Period applicable thereto.

SECTION 2.09. Termination and Reduction of Commitments; Increase in Revolving
Commitments. (a) Unless previously terminated, all Commitments shall terminate
on the Maturity Date.

(b)    The Borrowers may at any time terminate the Commitments upon (i) the
payment in full of all outstanding Loans, together with accrued and unpaid
interest thereon and on any Letters of Credit, (ii) the cancellation and return
of all outstanding Letters of Credit (or alternatively, with respect to each
such Letter of Credit, the furnishing to the Administrative Agent of a cash
deposit (or at the discretion of the Administrative Agent a back up standby
letter of credit satisfactory to the Administrative Agent and the Issuing Bank)
in an amount equal to 105% of the LC Exposure as of such date), (iii) the
payment in full of the accrued and unpaid fees, and (iv) the payment in full of
all reimbursable expenses and other Obligations, together with accrued and
unpaid interest thereon.

(c)    The Borrowers may 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 $5,000,000 and not less than $5,000,000
and (ii) the Borrowers shall not terminate or reduce the Revolving Commitments
if, after giving effect to any concurrent prepayment of the Revolving Loans in
accordance with Section 2.10, the Aggregate Revolving Exposure would exceed the
sum of (A) the lesser of (1) the aggregate Revolving Commitments and (2) the
Borrowing Base, minus (B) without duplication, Reserves.

(d)    The Borrower Representative shall notify the Administrative Agent of any
election to terminate or reduce the Commitments under paragraph (b) or (c) of
this Section at least five (5) 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 Representative pursuant to this Section shall be irrevocable; provided
that a notice of termination of the Commitments delivered by the Borrower
Representative 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 Representative (by notice to the Administrative Agent on or prior to
the specified effective date) if such condition is not satisfied. Any
termination or reduction of the Commitments shall be permanent. Each reduction
of the Commitments shall be made ratably among the Lenders in accordance with
their respective Commitments.

(e)    The Borrowers shall have the right to increase the Revolving Commitments
by obtaining additional Revolving Commitments, either from one or more of the
Lenders or another lending institution provided that (i) any such request for an
increase shall be in a minimum amount of $5,000,000, (ii) the Borrower
Representative, on behalf of the Borrowers, may make a maximum of four such
requests, (iii) after giving effect thereto, the sum of the total of the
additional Commitments does not exceed $30,000,000, (iv) the Administrative
Agent and the Issuing Bank have approved the identity of any such new Lender,
such approvals not to be unreasonably withheld, (v) any such new Lender assumes
all of the rights and obligations of a “Lender” hereunder, and (vi) the
procedures described in Section 2.09(f) have been satisfied. Nothing contained
in this Section 2.09 shall constitute, or otherwise be deemed to be, a
commitment on the part of any Lender to increase its Commitment hereunder at any
time.

35

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

(f)    Any amendment hereto for such an increase or addition shall be in form
and substance satisfactory to the Administrative Agent and shall only require
the written signatures of the Administrative Agent, the Borrowers and each
Lender being added or increasing its Commitment, subject only to the approval of
all Lenders if any such increase or addition would cause the Revolving
Commitments to exceed $130,000,000. As a condition precedent to such an increase
or addition, the Borrowers shall deliver to the Administrative Agent a
certificate of each Loan Party signed by an authorized officer of such Loan
Party (A) certifying and attaching the resolutions adopted by such Loan Party
approving or consenting to such increase, and (B) in the case of the Borrowers,
certifying that, before and after giving effect to such increase or addition,
(1) the representations and warranties contained in Article III and the other
Loan Documents are true and correct, except to the extent that such
representations and warranties specifically refer to an earlier date, in which
case they are true and correct as of such earlier date and (2) no Default
exists.

(g)    On the effective date of any such increase or addition, (i) any Lender
increasing (or, in the case of any newly added Lender, extending) its Revolving
Commitment shall make available to the Administrative Agent such amounts in
immediately available funds as the Administrative Agent shall determine, for the
benefit of the other Lenders, as being required in order to cause, after giving
effect to such increase or addition and the use of such amounts to make payments
to such other Lenders, each Lender’s portion of the outstanding Revolving Loans
of all the Lenders to equal its revised Applicable Percentage of such
outstanding Revolving Loans, and the Administrative Agent shall make such other
adjustments among the Lenders with respect to the Revolving Loans then
outstanding and amounts of principal, interest, commitment fees and other
amounts paid or payable with respect thereto as shall be necessary, in the
opinion of the Administrative Agent, in order to effect such reallocation and
(ii)  the Borrowers shall be deemed to have repaid and reborrowed all
outstanding Revolving Loans as of the date of any increase (or addition) in the
Revolving Commitments (with such reborrowing to consist of the Types of
Revolving Loans, with related Interest Periods if applicable, specified in a
notice delivered by the Borrower Representative, in accordance with the
requirements of Section 2.03). The deemed payments made pursuant to clause (ii)
of the immediately preceding sentence shall be accompanied by payment of all
accrued interest on the amount prepaid and, in respect of each Eurodollar Loan,
shall be subject to indemnification by the Borrowers pursuant to the provisions
of Section 2.16 if the deemed payment occurs other than on the last day of the
related Interest Periods. Within a reasonable time after the effective date of
any increase or addition, the Administrative Agent shall, and is hereby
authorized and directed to, revise the Commitment Schedule to reflect such
increase or addition and shall distribute such revised Commitment Schedule to
each of the Lenders and the Borrower Representative, whereupon such revised
Commitment Schedule shall replace the old Commitment Schedule and become part of
this Agreement.

SECTION 2.10. Repayment and Amortization of Loans; Evidence of Debt. (a) The
Borrowers hereby unconditionally promise to pay (i) to the Administrative Agent
for the account of each Revolving Lender the then unpaid principal amount of
each Revolving Loan on the Maturity Date, and (ii) to the Administrative Agent
the then unpaid amount of each Protective Advance on the earlier of the Maturity
Date and demand by the Administrative Agent.

(b)    At all times that Cash Dominion is in effect, on each Business Day, the
Administrative Agent shall apply all funds credited to the Collection Account on
such Business Day or the immediately preceding Business Day (at the discretion
of the Administrative Agent, whether or not immediately available) first to
prepay any Protective Advances that may be outstanding and second to prepay the
Revolving Loans (including Swingline Loans) and to cash collateralize
outstanding LC Exposure.

(c)    Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing the Indebtedness of the Borrowers 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.

(d)    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 Borrowers 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.

36

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

(e)    The entries made in the accounts maintained pursuant to paragraph (c) or
(d) of this Section 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 Borrowers to repay the Loans in
accordance with the terms of this Agreement.

(f)    Any Lender may request that Loans made by it be evidenced by a promissory
note. In such event, the Borrowers shall prepare, execute and deliver to such
Lender a promissory note payable to the order of such Lender (or, if requested
by such Lender, to such Lender and its registered assigns) and in a form
approved by the Administrative Agent. Thereafter, the Loans evidenced by such
promissory note and interest thereon shall at all times (including after
assignment pursuant to Section 9.04) be represented by one or more promissory
notes in such form payable to the order of the payee named therein (or, if such
promissory note is a registered note, to such payee and its registered assigns).

SECTION 2.11. Prepayment of Loans. (a) The Borrowers shall have the right at any
time and from time to time to prepay any Borrowing in whole or in part, subject
to prior notice in accordance with paragraph (f) of this Section and, if
applicable, payment of any break funding expenses under Section 2.16 but,
otherwise, without any premium or penalty.

(b)    In the event and on such occasion that the Aggregate Revolving Exposure
exceeds the sum of (i) the lesser of (A) the aggregate Revolving Commitments and
(B) the Borrowing Base, minus (ii) without duplication, Reserves, the Borrowers
shall prepay the Revolving Loans, LC Exposure and/or Swingline Loans or cash
collateralize LC Exposure in an account with the Administrative Agent pursuant
to Section 2.06(j), as applicable, in an aggregate amount equal to such excess.

(c)    In the event and on each occasion that any Net Proceeds are received by
or on behalf of any Loan Party in respect of any Prepayment Event, the Borrowers
shall, immediately after such Net Proceeds are received by any Loan Party,
prepay the Obligations as set forth in Section 2.11(e) below in an aggregate
amount equal to 100% of such Net Proceeds, provided that, in the case of any
event described in clause (a) or (b) of the definition of the term “Prepayment
Event”, if the Borrower Representative shall deliver to the Administrative Agent
a certificate of a Financial Officer to the effect that the Loan Parties (1)
have applied or (2) intend to apply the Net Proceeds from such event (or a
portion thereof specified in such certificate), within 180 days after receipt of
such Net Proceeds, as applicable, to acquire (or replace or rebuild) assets used
or to be used in the business of the Loan Parties, and certifying that no
Default has occurred and is continuing, then either (i) so long as Cash Dominion
is not in effect, no prepayment shall be required pursuant to this paragraph in
respect of the Net Proceeds specified in such certificate or (ii) if Cash
Dominion is in effect, then, if the Net Proceeds specified in such certificate
are to be applied to acquire, replace or rebuild such assets by (A) the
Borrowers, then such Net Proceeds shall be applied by the Administrative Agent
to reduce the outstanding principal balance of the Revolving Loans (without a
permanent reduction of the Revolving Commitment) and upon such application, the
Administrative Agent shall establish a Reserve against the Borrowing Base in an
amount equal to the amount of such proceeds so applied and (B) any Loan Party
that is not a Borrower, such Net Proceeds shall be deposited in a cash
collateral account, and in the case of either (A) or (B), thereafter, such funds
shall be made available to the applicable Loan Party as follows:

(1)    the Borrower Representative shall request a Revolving Borrowing
(specifying that the request is to use Net Proceeds pursuant to this Section) or
the applicable Loan Party shall request a release from the cash collateral
account be made in the amount needed;

(2)    so long as the conditions set forth in Section 4.02 have been met, the
Revolving Lenders shall make such Revolving Borrowing or the Administrative
Agent shall release funds from the cash collateral account; and

(3)    in the case of Net Proceeds applied against the Revolving Borrowing, the
Reserve established with respect to such insurance proceeds shall be reduced by
the amount of such Revolving Borrowing;

37

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

provided that to the extent of any such Net Proceeds therefrom that have not
been so applied by the end of such 180-day period, a prepayment shall be
required at such time in an amount equal to such Net Proceeds that have not been
so applied.

(d)    All amounts prepaid pursuant to Section 2.11(c) shall be applied, first
to prepay any Protective Advances that may be outstanding, pro rata, and second
to prepay the Revolving Loans (including Swingline Loans) without a
corresponding reduction in the Revolving Commitments and to cash collateralize
outstanding LC Exposure.

(e)    The Borrower Representative shall notify the Administrative Agent (and,
in the case of prepayment of a Swingline Loan, the Swingline Lender) by
telephone (confirmed by facsimile) of any prepayment hereunder (other than a
prepayment pursuant to Section 2.10(b)) not later than 10:00 a.m., Dallas, Texas
time, (i) in the case of prepayment of a Eurodollar Revolving Borrowing, three
(3) Business Days before the date of prepayment, or (ii) in the case of
prepayment of a CBFR Revolving Borrowing, on 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; provided
that, if a notice of prepayment is given in connection with a conditional notice
of termination of the Commitments as contemplated by Section 2.09, then such
notice of prepayment may be revoked if such notice of termination is revoked in
accordance with Section 2.09. Promptly following receipt of any such notice
relating to a Revolving Borrowing, the Administrative Agent shall advise the
Lenders of the contents thereof. Each partial prepayment of any Revolving
Borrowing shall be in an amount that would be permitted in the case of an
advance of a Revolving Borrowing of the same Type as provided in Section 2.02.
Each prepayment of a Revolving Borrowing shall be applied ratably to the
Revolving Loans included in the prepaid Borrowing. Prepayments shall be
accompanied by (i) accrued interest to the extent required by Section 2.13 and
(ii) break funding payments pursuant to Section 2.16.

SECTION 2.12. Fees. (a)  The Borrowers agree to pay to the Administrative Agent
for the account of each Lender a commitment fee, which shall accrue at the
Applicable Rate on the average daily amount of the Available Revolving
Commitment of such Lender during the period from and including the Effective
Date to but excluding the date on which the Revolving Commitments terminate.
Accrued commitment fees shall be payable in arrears on the first day of each
calendar quarter and on the date on which the Revolving Commitments terminate,
commencing on the first such date to occur after the date hereof. All commitment
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 Borrowers agree to pay (i) to the Administrative Agent for the
account of each Revolving Lender a participation fee with respect to its
participations in Letters of Credit, which shall accrue at the same Applicable
Rate used to determine the interest rate applicable to 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 a fronting
fee for each Letter of Credit issued by the Issuing Bank equal to a percentage
to be agreed between the Borrowers and the Issuing Bank, together with the
Issuing Bank’s standard fees and commissions with respect to the issuance,
amendment, cancellation, negotiation, transfer, presentment, renewal or
extension of any Letter of Credit or processing of drawings thereunder.
Participation fees and fronting fees accrued through and including the last day
of each calendar quarter shall be payable on the first day of each calendar
quarter following such last day, 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 paragraph
shall be payable within ten (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 Borrowers agree to pay to the Administrative Agent, for its own
account, fees payable in the amounts and at the times separately agreed upon
between the Borrowers and the Administrative Agent.

(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 commitment

38

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

fees and participation fees, to the Lenders. Fees paid shall not be refundable
under any circumstances.

SECTION 2.13. Interest. (a) The Loans comprising each CBFR Borrowing (including
each Swingline Loan) shall bear interest at the CB Floating Rate plus the
Applicable Rate.

(b)    The Loans comprising each Eurodollar Borrowing shall bear interest at the
Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the
Applicable Rate.

(c)    Each Protective Advance shall bear interest at the CB Floating Rate plus
the Applicable Rate for Revolving Loans plus 2%.

(d)    Notwithstanding the foregoing, during the occurrence and continuance of
an Event of Default, the Administrative Agent may, or, at the request of the
Required Lenders, shall, by notice to the Borrower Representative (which notice
may be revoked at the option of the Required Lenders notwithstanding any
provision of Section 9.02 requiring the consent of “each Lender affected
thereby” for reductions in interest rates), declare that (i) all Loans shall
bear interest at 2% plus the rate otherwise applicable to such Loans as provided
in the preceding paragraphs of this Section or (ii) in the case of any other
amount outstanding hereunder, such amount shall accrue at 2% plus the rate
applicable to such fee or other obligation as provided hereunder.

(e)    Accrued interest on each Loan (for CBFR Loans, accrued through the last
day of the prior calendar month) shall be payable in arrears on each Interest
Payment Date for such Loan and upon termination of the Commitments; provided
that (i) interest accrued pursuant to paragraph (d) of this Section shall be
payable on demand, (ii) in the event of any repayment or prepayment of any Loan
(other than a prepayment of a CBFR Revolving 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)    All interest hereunder shall be computed on the basis of a year of 360
days, except that interest computed by reference to the CB Floating 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 CB Floating 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 (which determination shall be
conclusive and binding absent manifest error) that adequate and reasonable means
do not exist for ascertaining, (including, without limitation, by means of an
Interpolated Rate) the Adjusted LIBO Rate or the LIBO Rate, as applicable, for
such Interest Period; or

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

then the Administrative Agent shall give notice thereof to the Borrower
Representative and the Lenders by electronic communication as provided in
Section 9.01 as promptly as practicable thereafter and, until the Administrative
Agent notifies the Borrower Representative 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
and any such Eurodollar Borrowing shall be repaid on the last day of the then
current Interest Period applicable thereto, and (ii) if any Borrowing Request
requests a Eurodollar Borrowing, such Borrowing shall be made as a CBFR
Borrowing.

39

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

SECTION 2.15. Increased Costs. (a) If any Change in Law shall:

(i)    impose, modify or deem applicable any reserve, special deposit, liquidity
or similar requirement (including any compulsory loan requirement, insurance
charge or other assessment) 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;

(ii)    impose on any Lender or the Issuing Bank or the London interbank market
any other condition, cost or expense (other than Taxes) affecting this Agreement
or Loans made by such Lender or any Letter of Credit or participation therein;
or

(iii)     subject any Recipient to any Taxes (other than (A) Indemnified Taxes,
(B) Taxes described in clauses (b) through (d) of the definition of Excluded
Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of
credit, commitments, or other obligations, or its deposits, reserves, other
liabilities or capital attributable;

and the result of any of the foregoing shall be to increase the cost to such
Lender or such other Recipient of making, continuing, converting into or
main-taining any Loan (or of maintaining its obligation to make any such Loan)
or to increase the cost to such Lender, the Issuing Bank or such other Recipient
of participating in, issuing or maintaining any Letter of Credit or to reduce
the amount of any sum received or receiv-able by such Lender, the Issuing Bank
or such other Recipient hereunder (whether of principal, interest or otherwise),
then the Borrowers will pay to such Lender, the Issuing Bank or such other
Recipient, as the case may be, such additional amount or amounts as will
compensate such Lender, the Issuing Bank or such other Recipient, 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 or liquidity 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 and liquidity), then from time to time the
Borrowers 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 shall be delivered to the Borrower Representative and shall be
conclusive absent manifest error. The Borrowers 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 shall not constitute a waiver of such
Lender’s or the Issuing Bank’s right to demand such compensation; provided that
the Borrowers shall not be required to compensate a Lender or the Issuing Bank
pursuant to this Section 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 Representative 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.

SECTION 2.16. Break Funding Payments. In the event of (a) the payment of any
principal of any Eurodollar Loan other than on the last day of an Interest
Period applicable thereto (including as a result of an Event of Default or

40

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

as a result of any prepayment pursuant to Section 2.11), (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 Eurodollar
Loan on the date specified in any notice delivered pursuant hereto (regardless
of whether such notice may be revoked under Section 2.09(d) and is revoked in
accordance therewith), or (d) the assignment of any Eurodollar Loan other than
on the last day of the Interest Period applicable thereto as a result of a
request by the Borrower Representative pursuant to Section 2.19 or 9.02(d),
then, in any such event, the Borrowers 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 Eurodollar
Loan had such event not occurred, at the Adjusted LIBO Rate that would have been
applicable to such Eurodollar 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 Eurodollar 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
London Eurodolloar market. A certifi-cate of any Lender setting forth any amount
or amounts that such Lender is entitled to receive pursuant to this Section
shall be delivered to the Borrower Representative and shall be conclusive absent
manifest error. The Borrowers shall pay such Lender the amount shown as due on
any such certificate within ten (10) days after receipt thereof.

SECTION 2.17. Withholding of Taxes; Gross-Up. (a) Payments Free of Taxes. Any
and all payments by or on account of any obligation of any Loan Party under any
Loan Document shall be made without deduction or withholding for any Taxes,
except as required by applicable law. If any applicable law (as determined in
the good faith discretion of an applicable withholding agent) requires the
deduction or withholding of any Tax from any such payment by a withholding
agent, then the applicable withholding agent shall be entitled to make such
deduction or withholding and shall timely pay the full amount deducted or
withheld to the relevant Governmental Authority in accordance with applicable
law and, if such Tax is an Indemnified Tax, then the sum payable by the
applicable Loan Party shall be increased as necessary so that after such
deduction or withholding has been made (including such deductions and
withholdings applicable to additional sums payable under this Section 2.17) the
applicable Recipient receives an amount equal to the sum it would have received
had no such deduction or withholding been made.
(b) Payment of Other Taxes by the Borrowers. The Loan Parties shall timely pay
to the relevant Governmental Authority in accordance with applicable law, or at
the option of the Administrative Agent timely reimburse it for, Other Taxes.
(c) Evidence of Payments. As soon as practicable after any payment of Taxes by
any Loan Party to a Governmental Authority pursuant to this Section 2.17, such
Loan Party 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.
(d) Indemnification by the Loan Parties. The Loan Parties shall jointly and
severally indemnify each Recipient, within ten (10) days after demand therefor,
for the full amount of any Indemnified Taxes (including Indemnified Taxes
imposed or asserted on or attributable to amounts payable under this Section)
payable or paid by such Recipient or required to be withheld or deducted from a
payment to such Recipient and any reasonable expenses arising therefrom or with
respect thereto, whether or not such Indemnified 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 any Loan Party by a Lender
(with a copy to the Administrative Agent), or by the Administrative Agent on its
own behalf or on behalf of a Lender, shall be conclusive absent manifest error.
(e) Indemnification by the Lenders. Each Lender shall severally indemnify the
Administrative Agent, within ten (10) days after demand therefor, for (i) any
Indemnified Taxes attributable to such Lender (but only to the extent that any
Loan Party has not already indemnified the Administrative Agent for such
Indemnified Taxes and without limiting the obligation of the Loan Parties to do
so), (ii) any Taxes attributable to such Lender’s failure to comply with the
provisions of Section 9.04(c) relating to the maintenance of a Participant
Register and (iii) any Excluded Taxes

41

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

attributable to such Lender, in each case, that are payable or paid by the
Administrative Agent in connection with any Loan Document, and any reasonable
expenses arising therefrom or with respect thereto, whether or not such 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 any Lender by the Administrative Agent shall be conclusive absent manifest
error. Each Lender hereby authorizes the Administrative Agent to set off and
apply any and all amounts at any time owing to such Lender under any Loan
Document or otherwise payable by the Administrative Agent to such Lender from
any other source against any amount due to the Administrative Agent under this
paragraph (e).
(f) Status of Lenders. (i) Any Lender that is entitled to an exemption from or
reduction of withholding Tax with respect to payments made under any Loan
Document shall deliver to the Borrower Representative and the Administrative
Agent, at the time or times reasonably requested by the Borrower Representative
or the Administrative Agent, such properly completed and executed documentation
reasonably requested by the Borrower Representative or the Administrative Agent
as will permit such payments to be made without withholding or at a reduced rate
of withholding. In addition, any Lender, if reasonably requested by the Borrower
Representative or the Administrative Agent, shall deliver such other
documentation prescribed by applicable law or reasonably requested by the
Borrower Representative or the Administrative Agent as will enable the Borrowers
or the Administrative Agent to determine whether or not such Lender is subject
to backup withholding or information reporting requirements. Notwithstanding
anything to the contrary in the preceding two sentences, the completion,
execution and submission of such documentation (other than such documentation
set forth in Section 2.17(f)(ii)(A), (ii)(B) and (ii)(D) below) shall not be
required if in the Lender’s reasonable judgment such completion, execution or
submission would subject such Lender to any material unreimbursed cost or
expense or would materially prejudice the legal or commercial position of such
Lender.
(ii) Without limiting the generality of the foregoing, in the event that any
Borrower is a U.S. Person,

(A) any Lender that is a U.S. Person shall deliver to the Borrower
Representative and the Administrative Agent on or prior to the date on which
such Lender becomes a Lender under this Agreement (and from time to time
thereafter upon the reasonable request of the Borrower Representative or the
Administrative Agent), executed originals of IRS Form W-9 certifying that such
Lender is exempt from U.S. Federal backup withholding tax;

(B) any Foreign Lender shall, to the extent it is legally entitled to do so,
deliver to the Borrower Representative and the Administrative Agent (in such
number of copies as shall be requested by the recipient) on or prior to the date
on which such Foreign Lender becomes a Lender under this Agreement (and from
time to time thereafter upon the reasonable request of the Borrower
Representative or the Administrative Agent), whichever of the following is
applicable:

(1) in the case of a Foreign Lender claiming the benefits of an income tax
treaty to which the United States is a party (x) with respect to payments of
interest under any Loan Document, executed originals of IRS Form W-8BEN
establishing an exemption from, or reduction of, U.S. Federal withholding Tax
pursuant to the “interest” article of such tax treaty and (y) with respect to
any other applicable payments under any Loan Document, IRS Form W-8BEN
establishing an exemption from, or reduction of, U.S. Federal withholding Tax
pursuant to the “business profits” or “other income” article of such tax treaty;

(2) in the case of a Foreign Lender claiming that its extension of credit will
generate U.S. effectively connected income, executed originals of IRS Form
W-8ECI;

(3) in the case of a Foreign Lender claiming the benefits of the exemption for
portfolio interest under Section 881(c) of the Code, (x) a certificate
substantially in the form of Exhibit F-1 to the effect that such Foreign Lender
is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10
percent shareholder” of a Borrower within the meaning of Section 881(c)(3)(B) of
the Code, or a “controlled foreign corporation” described in Section
881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed
originals of IRS Form W-8BEN; or

42

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

(4) to the extent a Foreign Lender is not the beneficial owner, executed
originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a
U.S. Tax Compliance Certificate substantially in the form of Exhibit F-2 or
Exhibit F-3, IRS Form W-9, and/or other certification documents from each
Beneficial Owner, as applicable; provided that if the Foreign Lender is a
partnership and one or more direct or indirect partners of such Foreign Lender
are claiming the portfolio interest exemption, such Foreign Lender may provide a
U.S. Tax Compliance Certificate substantially in the form of Exhibit F-4 on
behalf of each such direct and indirect partner;

(C) any Foreign Lender shall, to the extent it is legally entitled to do so,
deliver to the Borrower Representative and the Administrative Agent (in such
number of copies as shall be requested by the recipient) on or prior to the date
on which such Foreign Lender becomes a Lender under this Agreement (and from
time to time thereafter upon the reasonable request of the Borrower
Representative or the Administrative Agent), executed originals of any other
form prescribed by applicable law as a basis for claiming exemption from or a
reduction in U.S. Federal withholding Tax, duly completed, together with such
supplementary documentation as may be prescribed by applicable law to permit the
Borrowers or the Administrative Agent to determine the withholding or deduction
required to be made; and

(D) if a payment made to a Lender under any Loan Document would be subject to
U.S. Federal withholding Tax imposed by FATCA if such Lender were to fail to
comply with the applicable reporting requirements of FATCA (including those
contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender
shall deliver to the Borrower Representative and the Administrative Agent at the
time or times prescribed by law and at such time or times reasonably requested
by the Borrower Representative or the Administrative Agent such documentation
prescribed by applicable law (including as prescribed by Section
1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably
requested by the Borrower Representative or the Administrative Agent as may be
necessary for the Borrowers and the Administrative Agent to comply with their
obligations under FATCA and to determine that such Lender has complied with such
Lender’s obligations under FATCA or to determine the amount to deduct and
withhold from such payment. Solely for purposes of this clause (D), “FATCA”
shall include any amendments made to FATCA after the date of this Agreement.

Each Lender agrees that if any form or certification it previously delivered
expires or becomes obsolete or inaccurate in any respect, it shall update such
form or certification or promptly notify the Borrower Representative and the
Administrative Agent in writing of its legal inability to do so.

(g) Treatment of Certain Refunds. If any party determines, in its sole
discretion exercised in good faith, that it has received a refund of any Taxes
as to which it has been indemnified pursuant to this Section 2.17 (including by
the payment of additional amounts pursuant to this Section 2.17), it shall pay
to the indemnifying party an amount equal to such refund (but only to the extent
of indemnity payments made under this Section 2.17 with respect to the Taxes
giving rise to such refund), net of all out-of-pocket expenses (including Taxes)
of such indemnified party and without interest (other than any interest paid by
the relevant Governmental Authority with respect to such refund). Such
indemnifying party, upon the request of such indemnified party, shall repay to
such indemnified party the amount paid over pursuant to this paragraph (g) (plus
any penalties, interest or other charges imposed by the relevant Governmental
Authority) in the event that such indemnified party is required to repay such
refund to such Governmental Authority. Notwithstanding anything to the contrary
in this paragraph (g), in no event will the indemnified party be required to pay
any amount to an indemnifying party pursuant to this paragraph (g) the payment
of which would place the indemnified party in a less favorable net after-Tax
position than the indemnified party would have been in if the Tax subject to
indemnification and giving rise to such refund had not been deducted, withheld
or otherwise imposed and the indemnification payments or additional amounts
giving rise to such refund had never been paid. This paragraph (g) shall not be
construed to require any indemnified party to make available its Tax returns (or
any other information relating to its Taxes that it deems confidential) to the
indemnifying party or any other Person.
(h) Survival. Each party’s obligations under this Section 2.17 shall survive the
resignation or replacement of the Administrative Agent or any assignment of
rights by, or the replacement of, a Lender, the termination of the Commitments
and the repayment, satisfaction or discharge of all obligations under any Loan
Document.

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

(i) Defined Term. For purposes of this Section 2.17, the term “applicable law”
includes FATCA.

SECTION 2.18. Payments Generally; Allocation of Proceeds; Sharing of Set-offs.
(a) The Borrowers shall make each payment required to be made by them 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 2:00
p.m., 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 10 South Dearborn Street, 22nd Floor, Chicago, Illinois, except
payments to be made directly to the Issuing Bank or Swingline Lender as
expressly provided herein and except that payments pursuant to Sections 2.15,
2.16, 2.17 and 9.03 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)    Any proceeds of Collateral received by the Administrative Agent (i) not
constituting either (A) a specific payment of principal, interest, fees or other
sum payable under the Loan Documents (which shall be applied as specified by the
Borrowers), (B) a mandatory prepayment (which shall be applied in accordance
with Section 2.11) or (C) amounts to be applied from the Collection Account when
Cash Dominion is in effect (which shall be applied in accordance with Section
2.10(b)) or (ii) in any event, after an Event of Default has occurred and is
continuing and the Administrative Agent so elects or the Required Lenders so
direct, shall be applied ratably first, to pay any fees, indemnities, or expense
reimbursements including amounts then due to the Administrative Agent and the
Issuing Bank from the Borrowers (other than in connection with Banking Services
Obligations or Swap Agreement Obligations), second, to pay any fees or expense
reimbursements then due to the Lenders from the Borrowers (other than in
connection with Banking Services Obligations or Swap Agreement Obligations),
third, to pay interest due in respect of the Protective Advances, fourth, to pay
the principal of the Protective Advances, fifth, to pay interest then due and
payable on the Loans (other than the Protective Advances) ratably, sixth, to
prepay principal on the Loans (other than the Protective Advances), seventh, to
pay an amount to the Administrative Agent equal to one hundred five percent
(105%) of the aggregate undrawn face amount of all outstanding Letters of Credit
and the aggregate amount of any unpaid LC Disbursements, to be held as cash
collateral for such Obligations, eighth, to payment of any amounts owing with
respect to Banking Services Obligations and Swap Agreement Obligations up to and
including the amount most recently provided to the Administrative Agent pursuant
to Section 2.22, and ninth, to the payment of any other Secured Obligation due
to the Administrative Agent or any Lender by the Borrowers. Notwithstanding the
foregoing amounts received from any Loan Party shall not be applied to any
Excluded Swap Obligation of such Loan Party. Notwithstanding anything to the
contrary contained in this Agreement, unless so directed by the Borrower
Representative, or unless a Default is in existence, neither the Administrative
Agent nor any Lender shall apply any payment which it receives to any Eurodollar
Loan, except (a) on the expiration date of the Interest Period applicable
thereto or (b) in the event, and only to the extent, that there are no
outstanding CBFR Loans and, in any such event, the Borrowers shall pay the break
funding payment required in accordance with Section 2.16. The Administrative
Agent and the Lenders shall have the continuing and exclusive right to apply and
reverse and reapply any and all such proceeds and payments to any portion of the
Secured Obligations.

(c)At the election of the Administrative Agent, all payments of principal,
interest, LC Disbursements, fees, premiums, reimbursable expenses (including,
without limitation, all reimbursement for fees, costs and expenses pursuant to
Section 9.03), and other sums payable under the Loan Documents, may be paid from
the proceeds of Borrowings made hereunder whether made following a request by
the Borrower Representative pursuant to Section 2.03 or a deemed request as
provided in this Section or may be deducted from any deposit account of any
Borrower maintained with the Administrative Agent. The Borrowers hereby
irrevocably authorize (i) the Administrative Agent to make a Borrowing for the
purpose of paying each payment of principal, interest and fees as it becomes due
hereunder or any other amount due under the Loan Documents and agrees that all
such amounts charged shall constitute Loans (including Swingline Loans, but such
a Borrowing may only constitute a Protective Advance if it is to reimburse
costs, fees and expenses as described in Section 9.03) and that all such
Borrowings shall be deemed to have been requested

44

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

pursuant to Section 2.03, 2.04 or 2.05, as applicable, and (ii) the
Administrative Agent to charge any deposit account of any Borrower maintained
with the Administrative Agent for each payment of principal, interest and fees
as it becomes due hereunder or any other amount due under the Loan Documents.

(d)    If, except as otherwise expressly provided herein, 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 Swingline Loans and accrued interest thereon than the
proportion received by any other similarly situated Lender, then the Lender
receiving such greater proportion shall purchase (for cash at face value)
participations in the Loans and participations in LC Disbursements and Swingline
Loans 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 and Swingline Loans; 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, and
(ii) the provisions of this paragraph shall not be construed to apply to any
payment made by the Borrowers 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 Borrowers or any Subsidiary or Affiliate thereof (as to which the provisions
of this paragraph shall apply). Each 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 such Borrower rights of set-off and counterclaim with respect
to such participation as fully as if such Lender were a direct creditor of such
Borrower in the amount of such participation.

(e)    Unless the Administrative Agent shall have received notice from the
Borrower Representative 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 Borrowers will not make such payment, the Administrative
Agent may assume that the Borrowers have 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 Borrowers have 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.

(f)    If any Lender shall fail to make any payment required to be made by it
hereunder, then the Administrative Agent may, in its discretion (notwithstanding
any contrary provision hereof), (i) apply any amounts thereafter received by the
Administrative Agent for the account of such Lender to satisfy such Lender’s
obligations hereunder until all such unsatisfied obligations are fully paid
and/or (ii) hold any such amounts in a segregated account as cash collateral
for, and application to, any future funding obligations of such Lender
hereunder; application of amounts pursuant to (i) and (ii) above shall be made
in any order determined by the Administrative Agent in its discretion.

SECTION 2.19. Mitigation Obligations; Replacement of Lenders.

(a)    If any Lender requests compensation under Section 2.15, or if the
Borrowers are required to pay any Indemnified Taxes or additional amounts 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 Borrowers hereby agree to pay all reasonable costs and expenses
incurred by any Lender in connection with any such designation or assignment.

45

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

(b)    If any Lender requests compensation under Section 2.15, or if the
Borrowers are required to pay any Indemnified Taxes or additional amounts to any
Lender or any Governmental Authority for the account of any Lender pursuant to
Section 2.17, or if any Lender becomes a Defaulting Lender, then the Borrowers
may, at their 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 9.04), all its interests, rights (other than its existing rights to
payments pursuant to Section 2.15 or 2.17) and obligations under this Agreement
and other Loan Documents to an assignee that shall assume such obligations
(which assignee may be another Lender, if a Lender accepts such assignment);
provided that (i) the Borrowers shall have received the prior written consent of
the Administrative Agent (and in circumstances where its consent would be
required under Section 9.04, the Issuing Bank and the Swingline Lender), which
consent shall not unrea-sonably be withheld, (ii) such Lender shall have
received payment of an amount equal to the outstanding principal of its Loans
and funded participations in LC Disbursements and Swingline Loans, 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 Borrowers (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 Borrowers to require such assignment and delegation
cease to apply.
    
SECTION 2.20. Defaulting Lenders. Notwithstanding any provision of this
Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the
following provisions shall apply for so long as such Lender is a Defaulting
Lender:

(a)    fees shall cease to accrue on the unfunded portion of the Revolving
Commitment of such Defaulting Lender pursuant to Section 2.12(a);

(b)    the Commitment and Revolving Exposure of such Defaulting Lender shall not
be included in determining whether the Required Lenders have taken or may take
any action hereunder (including any consent to any amendment, waiver or other
modification pursuant to Section 9.02) or under any other Loan Document;
provided, that, except as otherwise provided in Section 9.02, this clause (b)
shall not apply to the vote of a Defaulting Lender in the case of an amendment,
waiver or other modification requiring the consent of such Lender or each Lender
directly affected thereby;

(c)     if any Swingline Exposure or LC Exposure exists at the time a Lender
becomes a Defaulting Lender then:

(i)all or any part of the Swingline Exposure and LC Exposure of such Defaulting
Lender shall be reallocated among the non-Defaulting Lenders in accordance with
their respective Applicable Percentages but only to the extent that (x) the
conditions set forth in Section 4.02 are satisfied at the time of such
reallocation (and, unless the Borrower Representative shall have otherwise
notified the Administrative Agent at such time, the Borrowers shall be deemed to
have represented and warranted that such conditions are satisfied at such time)
and (y) the sum of all non-Defaulting Lenders’ Revolving Exposures plus such
Defaulting Lender’s Swingline Exposure and LC Exposure does not exceed the total
of all non-Defaulting Lenders’ Revolving Commitments (no reallocation hereunder
shall constitute a waiver or a release of any party hereunder arising from such
Lender having become a Defaulting Lender);

(ii)    if the reallocation described in clause (i) above cannot, or can only
partially, be effected, the Borrowers shall within one (1) Business Day
following notice by the Administrative Agent (x) first, prepay such Swingline
Exposure and (y) second, cash collateralize, for the benefit of the Issuing
Bank, the Borrowers’ obligations corresponding to such Defaulting Lender’s LC
Exposure (in both cases, after giving effect to any partial reallocation
pursuant to clause (i) above) in accordance with the procedures set forth in
Section 2.06(j) for so long as such LC Exposure is outstanding;

46

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

(iii)    if the Borrowers cash collateralize any portion of such Defaulting
Lender’s LC Exposure pursuant to clause (ii) above, the Borrowers shall not be
required to pay any fees to such Defaulting Lender pursuant to Section 2.12(b)
with respect to such Defaulting Lender’s LC Exposure during the period such
Defaulting Lender’s LC Exposure is cash collateralized;

(iv)    if the LC Exposure of the non-Defaulting Lenders is reallocated pursuant
to clause (i) above, then the fees payable to the Lenders pursuant to Sections
2.12(a) and 2.12(b) shall be adjusted in accordance with such non-Defaulting
Lenders’ Applicable Percentages; and

(v)    if all or any portion of such Defaulting Lender’s LC Exposure is neither
reallocated nor cash collateralized pursuant to clause (i) or (ii) above, then,
without prejudice to any rights or remedies of the Issuing Bank or any other
Lender hereunder, all letter of credit fees payable under Section 2.12(b) with
respect to such Defaulting Lender’s LC Exposure shall be payable to the Issuing
Bank until and to the extent that such LC Exposure is reallocated and/or cash
collateralized; and

(d)    so long as such Lender is a Defaulting Lender, the Issuing Bank shall not
be required to issue, amend, renew, extend or increase any Letter of Credit,
unless it is satisfied that such Defaulting Lender’s then outstanding LC
Exposure will be 100% covered by the Commitments of the non-Defaulting Lenders
and/or cash collateral will be provided by the Borrowers in accordance with
Section 2.20(c), and participating interests in any such newly issued or
increased Letter of Credit shall be allocated among non-Defaulting Lenders in a
manner consistent with Section 2.20(c)(i) (and such Defaulting Lender shall not
participate therein).

If (i) a Bankruptcy Event with respect to the Parent of any Lender shall occur
following the date hereof and for so long as such event shall continue or (ii)
the Issuing Bank has a good faith belief that any Lender has defaulted in
fulfilling its obligations under one or more other agreements in which such
Lender commits to extend credit, the Issuing Bank shall not be required to
issue, amend or increase any Letter of Credit, unless the Issuing Bank shall
have entered into arrangements with the Borrowers or such Lender, satisfactory
to the Issuing Bank to defease any risk to it in respect of such Lender
hereunder.

In the event that each of the Administrative Agent, the Borrowers, the Issuing
Bank and the Swingline Lender agrees that a Defaulting Lender has adequately
remedied all matters that caused such Lender to be a Defaulting Lender, then LC
Exposure of the Lenders shall be readjusted to reflect the inclusion of such
Lender’s Revolving Commitment and on the date of such readjustment such Lender
shall purchase at par such of the Loans of the other Lenders (other than
Swingline Loans) as the Administrative Agent shall determine may be necessary in
order for such Lender to hold such Loans in accordance with its Applicable
Percentage. No change hereunder from Defaulting Lender to Lender will constitute
a waiver or release of any claim of any party hereunder arising from such Lender
having been a Defaulting Lender.

SECTION 2.21. Returned Payments. If after receipt of any payment which is
applied to the payment of all or any part of the Obligations (including a
payment effected through exercise of a right of setoff), the Administrative
Agent or any Lender is for any reason compelled to surrender such payment or
proceeds to any Person because such payment or application of proceeds is
invalidated, declared fraudulent, set aside, determined to be void or voidable
as a preference, impermissible setoff, or a diversion of trust funds, or for any
other reason (including pursuant to any settlement entered into by the
Administrative Agent or such Lender in its discretion), then the Obligations or
part thereof intended to be satisfied shall be revived and continued and this
Agreement shall continue in full force as if such payment or proceeds had not
been received by the Administrative Agent or such Lender. The provisions of this
Section 2.21 shall be and remain effective notwithstanding any contrary action
which may have been taken by the Administrative Agent or any Lender in reliance
upon such payment or application of proceeds. The provisions of this Section
2.21 shall survive the termination of this Agreement.

SECTION 2.22. Banking Services and Swap Agreements. Each Lender or Affiliate
thereof providing Banking Services for, or having Swap Agreements with, any Loan
Party shall deliver to the Administrative Agent, promptly after entering into
such Banking Services or Swap Agreements, written notice setting forth the
aggregate amount of

47

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

all Banking Services Obligations and Swap Agreement Obligations of such Loan
Party to such Lender or Affiliate (whether matured or unmatured, absolute or
contingent). In addition, each such Lender or Affiliate thereof shall deliver to
the Administrative Agent, from time to time after a significant change therein
or upon a request therefor, a summary of the amounts due or to become due in
respect of such Banking Services Obligations and Swap Agreement Obligations. The
most recent information provided to the Administrative Agent shall be used in
determining the amounts to be applied in respect of such Banking Services
Obligations and/or Swap Agreement Obligations pursuant to Section 2.18(b).

ARTICLE III

Representations and Warranties

Each Loan Party represents and warrants to the Lenders that:

SECTION 3.01. Organization; Powers. Each Loan Party and its 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 as could not reasonably be
expected, individually or in the aggregate, to have Material Adverse Effect, is
qualified to do business in, and is in good standing in, every jurisdiction
where such qualification is required.
 
SECTION 3.02. Authorization; Enforceability. The Transactions are within each
Loan Party’s organizational powers and have been duly authorized by all
necessary organizational actions and, if required, actions by equity holders.
The Loan Documents to which each Loan Party is a party have been duly executed
and delivered by such Loan Party and constitute a legal, valid and binding
obligation of such Loan Party, enforceable in accordance with its terms, subject
to applicable bankruptcy, insolvency, reorganization, moratorium or other laws
affecting creditors’ rights generally and subject to general principles of
equity, regardless of whether considered in a proceeding in equity or at law.

SECTION 3.03. Governmental Approvals; No Conflicts. The Transactions (a) do not
require any consent or approval of, registration or filing with, or any other
action by, any Governmental Authority, except such as have been obtained or made
and are in full force and effect and except for filings necessary to perfect
Liens created pursuant to the Loan Documents, (b) will not violate any
Requirement of Law applicable to any Loan Party or any of its Subsidiaries, (c)
will not violate or result in a default under any indenture, agreement or other
instrument binding upon any Loan Party or any of its Subsidiaries or the assets
of any Loan Party or any of its Subsidiaries, or give rise to a right thereunder
to require any payment to be made by any Loan Party or any of its Subsidiaries,
and (d) will not result in the creation or imposition of any Lien on any asset
of any Loan Party or any of its Subsidiaries, except Liens created pursuant to
the Loan Documents.

SECTION 3.04. Financial Condition; No Material Adverse Change. (a) The Borrowers
have heretofore furnished to the Lenders the (i) audited consolidated balance
sheet and statements of income, stockholders equity and cash flows of Compressco
Partners as of and for the fiscal year ended December 31, 2012 and (ii)
unaudited consolidated balance sheet and statements of income, stockholders
equity and cash flows of Compressco Partners as of and for the fiscal quarter
and the portion of the fiscal year ended June 30, 2013, certi-fied by a
Financial Officer. Such financial state-ments present fairly, in all material
respects, the financial position and results of operations and cash flows of the
Borrowers and their consolidated Subsidiaries as of such dates and for such
periods in accordance with GAAP, subject to normal year‑end audit adjustments
(all of which, when taken as a whole, would not be materially adverse) and the
absence of footnotes in the case of the statements referred to in clause (ii)
above.

(b)    Since December 31, 2012, no development or event has occurred that has
had, or could reasonably be expected to have, a Material Adverse Effect.

SECTION 3.05. Properties. (a) As of the date of this Agreement, Schedule 3.05
sets forth the address of each parcel of real property that is owned or leased
by each Loan Party. Each of such leases and subleases is valid and enforceable
in accordance with its terms and is in full force and effect, and no default by
any party to any such lease

48

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

or sublease exists. Each of the Loan Parties and its Subsidiaries has good and
indefeasible title to, or valid leasehold or other interests in, all of its real
and personal property, subject only to Permitted Encumbrances, other Liens
permitted by Section 6.02, and any other defects in title that could not
reasonably be expected, individually or in the aggregate, to have a Material
Adverse Effect.

(b)    Each Loan Party and its Subsidiaries owns, or is licensed to use, all
trademarks, tradenames, copyrights, patents and other intellectual property
necessary to its business as currently conducted, except as would not be
expected, individually or in the aggregate, to have a Material Adverse Effect, a
correct and complete list of which, as of the date of this Agreement, is set
forth on Schedule 3.05, and, except as set forth on Schedule 3.05, each Loan
Party’s rights thereto are not subject to any licensing agreement or similar
arrangement. The use thereof by each Loan Party and its Subsidiaries does not
infringe in any material respect upon the rights of any other Person, except as
would not reasonably be expected to have a Material Adverse Effect.

SECTION 3.06. Litigation and Environmental Matters. (a) There are no actions,
suits or proceedings by or before any arbitrator or Governmental Authority
pending against or, to the knowledge of any Loan Party, threatened against or
affecting any Loan Party or any of its Subsidiaries (i) as to which there is a
reasonable possibility of an adverse determination and that, if adversely
determined, could reasonably be expected, individually or in the aggregate, to
result in a Material Adverse Effect (other than the Disclosed Matters) or (ii)
that involve this Agreement or the Transactions.

(b)    Except for the Disclosed Matters and any other matters that, individually
or in the aggregate, could not reasonably be expected to result in a Material
Adverse Effect (i) no Loan Party nor any of its Subsidiaries has received notice
of any claim with respect to any Environmental Liability or knows of any basis
for any Environmental Liability and (ii) no Loan Party nor any of its
Subsidiaries (1) 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 or (2) has become subject to any Environmental Liability.

(c)    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 Loan Party and its
Subsidiaries is in compliance with all Requirements of Law 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. No Default has occurred and is continuing.

SECTION 3.08. Investment Company Status. No Loan Party or any Subsidiary is an
“investment company” as defined in, or subject to regulation under, the
Investment Company Act of 1940.

SECTION 3.09. Taxes. Each Loan Party 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
Taxes that are being Properly Contested. No tax liens have been filed (except
tax liens that are being Properly Contested) and no material claims are being
asserted with respect to any such taxes.

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 (based on the assumptions used for purposes
of Statement of Financial Accounting Standards No. 87) did not, as of the date
of the most recent financial statements reflecting such amounts, exceed by more
than $1,000,000 the fair market value of the assets of such Plan, and the
present value of all accumulated benefit obligations of all underfunded Plans
(based on the assumptions used for purposes of Statement of Financial Accounting
Standards No. 87) did not, as of the date of the most recent financial
statements reflecting such amounts, exceed by more than $1,000,000 the fair
market value of the assets of all such underfunded Plans.

49

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

SECTION 3.11. Disclosure. None of the reports, financial statements,
certificates or other information furnished by or on behalf of any Loan Party to
the Administrative Agent or any Lender in connection with the negotiation of
this Agreement or any other Loan Document (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 Loan Parties represent only
that such information was prepared in good faith based upon assumptions believed
to be reasonable at the time delivered and, if such projected financial
information was delivered prior to the Effective Date, as of the Effective Date.

SECTION 3.12. Material Agreements. All agreements and contracts to which any
Loan Party is a party or is bound as of the date of this Agreement that are
individually material to the business and operations of the Loan Parties taken
as a whole are listed on Schedule 3.12 and all material agreements and contracts
of any Loan Party with Affiliates of any Loan Party (other than (i) agreements
and contracts between or among any one or more Loan Parties only and not
involving any Affiliate that is not a Loan Party and (ii) agreements and
contracts that are entered into in accordance with the terms of the Omnibus
Agreement) as of the date hereof are listed on Schedule 3.12. No Loan Party, or
with respect to the Omnibus Agreement and any material agreement entered into in
accordance with its terms, no Loan Party or Affiliate of such Loan Party party
to any such agreement, is in default in the performance, observance or
fulfillment of any of the obligations, covenants or conditions contained in (i)
any material agreement or contract with an Affiliate, including the Omnibus
Agreement and any material agreement or contract entered into in accordance with
the terms of the Omnibus Agreement or (ii) any agreement to which it is a party
that is individually material to the business and operations of the Loan Parties
taken as a whole and, in each case, has or is otherwise required to be filed or
summarized in any filing with the SEC under applicable rules and regulations,
except any default that would not reasonably be expected, individually or in the
aggregate, to have a Material Adverse Effect.

SECTION 3.13. Solvency. (a) Immediately after the consummation of the
Transactions to occur on the Effective Date, (i) the fair value of the assets of
each Loan Party, at a fair valuation, will exceed its debts and liabilities,
subordinated, contingent or otherwise, (ii) the present fair saleable value of
the property of each Loan Party will be greater than the amount that will be
required to pay the probable liability of its debts and other liabilities,
subordinated, contingent or otherwise, as such debts and other liabilities
become absolute and matured; (iii) each Loan Party will be able to pay its debts
and liabilities, subordinated, contingent or otherwise, as such debts and
liabilities become absolute and matured, and (iv) no Loan Party will have
unreasonably small capital with which to conduct the business in which it is
engaged as such business is now conducted and is proposed to be conducted after
the Effective Date.

(b)    No Loan Party intends to or believes that it will incur debts beyond its
ability to pay such debts as they mature, taking into account the timing of and
amounts of cash to be received by it and the timing of the amounts of cash to be
payable on or in respect of its Indebtedness.

SECTION 3.14. Insurance. Schedule 3.14 sets forth a description of all insurance
maintained by or on behalf of the Loan Parties and their Subsidiaries as of the
Effective Date. As of the Effective Date, all premiums in respect of such
insurance have been paid. Each Borrower maintains, and has caused each
Subsidiary to maintain, with financially sound and reputable insurance
companies, insurance on all their real and personal property in such amounts,
subject to such deductibles and self-insurance retentions and covering such
properties and risks as are adequate and customarily maintained by companies
engaged in the same or similar businesses operating in the same or similar
locations. Discuss current structure of insurance coverage.

SECTION 3.15. Capitalization and Subsidiaries. Schedule 3.15 sets forth (a) a
correct and complete list of the name and relationship to the Borrowers of each
Subsidiary of the Borrowers as of the date hereof, (b) a true and complete
listing of each class of each of the Borrowers’ authorized Equity Interests, of
which all of such issued Equity Interests are validly issued, outstanding, fully
paid and non-assessable as of the date hereof, and (c) the type of entity of
each Borrower and each of its Subsidiaries. All of the issued and outstanding
Equity Interests owned by any Loan Party have been (to the extent such concepts
are relevant with respect to such ownership interests) duly authorized and
issued and are fully paid and non‑assessable. Other than as reflected in the
financial statements delivered to the Administrative Agent pursuant to the terms
of this Agreement, there are no outstanding commitments or other

50

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

obligations of any Loan Party to issue, and no options, warrants or other rights
of any Person to acquire, any shares of any class of capital stock or other
equity interests of any Loan Party.

SECTION 3.16. Security Interest in Collateral. The provisions of the Security
Agreements create legal and valid Liens on all the Collateral described therein
in favor of the Administrative Agent, for the benefit of the Secured Parties,
and when financing statements and other filings are filed in the appropriate
offices and other actions specified therein to be taken are taken with respect
thereto, such Liens will constitute perfected and continuing Liens on such
Collateral, securing the Secured Obligations, enforceable against the applicable
Loan Party, and having priority over all other Liens on such Collateral subject
to (a) Permitted Encumbrances and other Liens permitted by section 6.02, to the
extent any such Permitted Encumbrances or other Liens would have priority over
the Liens in favor of the Administrative Agent pursuant to any applicable law
and (b) Liens perfected only by control or possession (including possession of
any certificate of title) to the extent the Administrative Agent has not
obtained or does not maintain control or possession of such Collateral.

SECTION 3.17. Employment Matters. As of the Effective Date, there are no
strikes, lockouts or slowdowns against any Loan Party or any Subsidiary pending
or, to the knowledge of the Borrowers, threatened. Except as would not
reasonably be expected, individually or in the aggregate, to have a Material
Adverse Effect, the hours worked by and payments made to employees of the Loan
Parties and the Subsidiaries have not been in violation of the Fair Labor
Standards Act or any other applicable Federal, state, local or foreign law
dealing with such matters, and all payments due from any Loan Party or any
Subsidiary, or for which any claim may be made against any Loan Party or any
Subsidiary, on account of wages and employee health and welfare insurance and
other benefits, have been paid or accrued as a liability on the books of the
Loan Party or such Subsidiary.

SECTION 3.18. Common Enterprise. Each Loan Party expects to derive benefit (and
its board of directors or other governing body has determined that it may
reasonably be expected to derive benefit), directly and indirectly, from the
credit extended by the Lenders to the Borrowers hereunder. Each Loan Party has
determined that execution, delivery, and performance of this Agreement and any
other Loan Documents to be executed by such Loan Party is within its purpose, in
furtherance of its direct and/or indirect business interests, will be of direct

condition upon (a) the ability of such Loan Party or any of its Subsidiaries to
create, incur or permit to exist any Lien upon any of its property or assets to

apply to any extension or renewal of, or any amendment or modification expanding
the scope of, any such restriction or condition), (iii) the foregoing shall not
apply to customary restrictions and conditions contained in agreements relating
to the sale of a Subsidiary pending such sale, provided such restrictions and
conditions apply only to the Subsidiary that is to be sold and such sale is
permitted hereunder, (iv) clause (a) of the foregoing shall not apply to
restrictions or conditions imposed by any agreement relating to secured
Indebtedness permitted by this Agreement if such restrictions or conditions

ARTICLE VIII

The Administrative Agent

SECTION 8.01. Appointment. Each of the Lenders, on behalf of itself and any of
its Affiliates that are Secured Parties, and the Issuing Bank hereby irrevocably
appoints the Administrative Agent as its agent and authorizes the Administrative
Agent to take such actions on its behalf, including execution of the other Loan
Documents, and to exercise such powers as are delegated to the Administrative
Agent by the terms of the Loan Documents, together with such actions and powers
as are reasonably incidental thereto. In addition, to the extent required under
the laws of any jurisdiction other than the U.S., each of the Lenders and the
Issuing Bank hereby grants to the Administrative Agent any required powers of
attorney to execute any Collateral Document governed by the laws of such
jurisdiction on such Lender’s or Issuing Bank’s behalf. The provisions of this
Article are solely for the benefit of the Administrative Agent and the Lenders
(including the Swingline Lender and the Issuing Bank), and the Loan Parties
shall not have rights as a third party beneficiary of any of such provisions. It
is understood and agreed that the use of the term “agent” as used herein or in
any other Loan Documents (or any similar term) with reference to the
Administrative Agent is not intended to connote any fiduciary or other implied
(or express) obligations arising under agency doctrine of any applicable law.
Instead, such term is used as a matter of market custom, and is intended to
create or reflect only an administrative relationship between independent
contracting parties.

SECTION 8.02. Rights as a Lender. The bank serving as the Administrative 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 Affili-ates may accept deposits
from, lend money to and generally engage in any kind of business with any Loan
Party or any Subsidiary or any Affiliate thereof as if it were not the
Administrative Agent hereunder.

SECTION 8.03. Duties and Obligations. The Administrative Agent 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
Administrative Agent shall not be subject to any fiduciary or other implied
duties, regardless of whether a Default has occurred and is continuing, (b) the
Administrative 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 the Administrative Agent is
required to exercise as directed 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 9.02), and, (c) except as expressly set
forth in the Loan Documents, the Administrative Agent shall not have any duty to
disclose, and shall not be liable for the failure to disclose, any information
relating to any Loan Party or any Subsidiary that is communicated to or obtained
by the bank serving as Administrative Agent or any of its Affiliates in any
capacity. The Administrative 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 9.02) or in the absence of its own gross
negligence or willful misconduct as determined by a final nonappealable judgment
of a court of competent jurisdiction. The Administrative Agent shall be deemed
not to have knowledge of any Default unless and until written notice thereof is
given to the Administrative Agent by the Borrower Representative or a Lender,
and the Administrative 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 with any Loan
Document, (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, (v) the creation, perfection or
priority of Liens on the

72

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

Collateral or the existence of the Collateral, or (vi) 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 the
Administrative Agent.

SECTION 8.04. Reliance. The Administrative Agent shall be entitled to rely upon,
and shall not incur any liability for relying upon, any notice, request,
certificate, consent, statement, instrument, document or other writing believed
by it to be genuine and to have been signed or sent by the proper Person. The
Administrative Agent also may rely upon any statement made to it orally or by
telephone and believed by it to be made by the proper Person, and shall not
incur any liability for relying thereon. The Administrative Agent may consult
with legal counsel (who may be counsel for the Borrowers), 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.

SECTION 8.05. Actions through Sub-Agents. The Administrative Agent may perform
any and all of its duties and exercise its rights and powers by or through any
one or more sub-agents appointed by the Administrative Agent. The Administrative
Agent and any such sub-agent may perform any and all of 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 the Administrative 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 the
Administrative Agent.

SECTION 8.06. Resignation. 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 Representative. Upon any such resignation, the Required Lenders shall
have the right, in consultation with the Borrowers, to appoint a successor. If
no successor shall have been so appointed by the Required Lenders and shall have
accepted such appointment within thirty (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 New
York, New York, or an Affiliate of any such bank. Upon the acceptance of its
appointment as Administrative Agent hereunder by its 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 and under
the other Loan Documents. The fees payable by the Borrowers to a successor
Administrative Agent shall be the same as those payable to its predecessor,
unless otherwise agreed by the Borrowers and such successor. Notwithstanding the
foregoing, in the event no successor Administrative Agent shall have been so
appointed and shall have accepted such appointment within thirty (30) days after
the retiring Administrative Agent gives notice of its intent to resign, the
retiring Administrative Agent may give notice of the effectiveness of its
resignation to the Lenders, the Issuing Bank and the Borrowers, whereupon, on
the date of effectiveness of such resignation stated in such notice, (a) the
retiring Administrative Agent shall be discharged from its duties and
obligations hereunder and under the other Loan Documents, provided that, solely
for purposes of maintaining any security interest granted to the Administrative
Agent under any Collateral Document for the benefit of the Secured Parties, the
retiring Administrative Agent shall continue to be vested with such security
interest as collateral agent for the benefit of the Secured Parties and, in the
case of any Collateral in the possession of the Administrative Agent, shall
continue to hold such Collateral, in each case until such time as a successor
Administrative Agent is appointed and accepts such appointment in accordance
with this paragraph (it being understood and agreed that the retiring
Administrative Agent shall have no duly or obligation to take any further action
under any Collateral Document, including any action required to maintain the
perfection of any such security interest), and (b) the Required Lenders shall
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent, provided that (i) all payments required to
be made hereunder or under any other Loan Document to the Administrative Agent
for the account of any Person other than the Administrative Agent shall be made
directly to such Person and (ii) all notices and other communications required
or contemplated to be given or made to the Administrative Agent shall also
directly be given or made to each Lender and the Issuing Bank. Following the
effectiveness of the Administrative Agent’s resignation from its capacity as
such, the provisions of this Article, Section 2.17(d) and Section 9.03, as well
as any exculpatory, reimbursement and indemnification provisions set forth in
any other Loan Document, 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

73

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

omitted to be taken by any of them while it was acting as Administrative Agent
and in respect of the matters referred to in the proviso under clause (a) above.

SECTION 8.07. Non-Reliance.

(a) Each Lender acknowledges and agrees that the extensions of credit made
hereunder are commercial loans and letters of credit and not investments in a
business enterprise or securities. Each Lender further represents that it is
engaged in making, acquiring or holding commercial loans in the ordinary course
of its business and has, independently and without reliance upon the
Administrative 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 as a Lender, and to make, acquire or hold
Loans hereunder. Each Lender shall, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
informa-tion (which may contain material, non-public information within the
meaning of the United States securities laws concerning the Borrowers and their
Affiliates) 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 and in deciding whether or to the extent to which it
will continue as a Lender or assign or otherwise transfer its rights, interests
and obligations hereunder.

(b) Each Lender hereby agrees that (i) it has requested a copy of each Report
prepared by or on behalf of the Administrative Agent; (ii) the Administrative
Agent (A) makes no representation or warranty, express or implied, as to the
completeness or accuracy of any Report or any of the information contained
therein or any inaccuracy or omission contained in or relating to a Report and
(B) shall not be liable for any information contained in any Report; (iii) the
Reports are not comprehensive audits or examinations, and that any Person
performing any field examination will inspect only specific information
regarding the Loan Parties and will rely significantly upon the Loan Parties’
books and records, as well as on representations of the Loan Parties’ personnel
and that the Administrative Agent undertakes no obligation to update, correct or
supplement the Reports; (iv) it will keep all Reports confidential and strictly
for its internal use, not share the Report with any Loan Party or any other
Person except as otherwise permitted pursuant to this Agreement; and (v) without
limiting the generality of any other indemnification provision contained in this
Agreement, it will pay and protect, and indemnify, defend, and hold the
Administrative Agent and any such other Person preparing a Report harmless from
and against, the claims, actions, proceedings, damages, costs, expenses, and
other amounts (including reasonable attorneys’ fees) incurred by the
Administrative Agent or any such other Person as the direct or indirect result
of any third parties who might obtain all or part of any Report through the
indemnifying Lender.
    
SECTION 8.08. Not Partners or Co-Venturers; Administrative Agent as
Representative of the Secured Parties. (a) The Lenders are not partners or
co-venturers, and no Lender shall be liable for the acts or omissions of, or
(except as otherwise set forth herein in case of the Administrative Agent)
authorized to act for, any other Lender. The Administrative Agent shall have the
exclusive right on behalf of the Lenders to enforce the payment of the principal
of and interest on any Loan after the date such principal or interest has become
due and payable pursuant to the terms of this Agreement.
(b) In its capacity, the Administrative Agent is a “representative” of the
Secured Parties within the meaning of the term “secured party” as defined in the
New York Uniform Commercial Code. Each Lender authorizes the Administrative
Agent to enter into each of the Collateral Documents to which it is a party and
to take all action contemplated by such documents. Each Lender agrees that no
Secured Party (other than the Administrative Agent) shall have the right
individually to seek to realize upon the security granted by any Collateral
Document, it being understood and agreed that such rights and remedies may be
exercised solely by the Administrative Agent for the benefit of the Secured
Parties upon the terms of the Collateral Documents. In the event that any
Collateral is hereafter pledged by any Person as collateral security for the
Secured Obligations, the Administrative Agent is hereby authorized, and hereby
granted a power of attorney, to execute and deliver on behalf of the Secured
Parties any Loan Documents necessary or appropriate to grant and perfect a Lien
on such Collateral in favor of the Administrative Agent on behalf of the Secured
Parties.

(d) Electronic Systems.

(i)    Each Loan Party agrees that the Administrative Agent may, but shall not
be obligated to, make Communications (as defined below) available to the Issuing
Bank and the other Lenders by posting the Communications on Debt Domain,
Intralinks, Syndtrak, ClearPar or a substantially similar Electronic System.

(ii)    Any Electronic System used by the Administrative Agent is provided “as
is” and “as available.” The Agent Parties (as defined below) do not warrant the
adequacy of such Electronic Systems and expressly disclaim liability for errors
or omissions in the Communications. No warranty of any kind, express, implied or
statutory, including any warranty of merchantability, fitness for a particular
purpose, non-infringement of third-party rights or freedom from viruses or other
code defects, is made by any Agent Party in connection with the Communications
or any Electronic System. In no event shall the Administrative Agent or any of
its Related Parties (collectively, the “Agent Parties”) have any liability to
the Borrowers or the other Loan Parties, any Lender, the Issuing Bank or any
other Person or entity for damages of any kind, including direct or indirect,
special, incidental or consequential damages, losses or expenses (whether in
tort, contract or otherwise) arising out of any Borrower’s, any Loan Party’s or
the Administrative Agent’s transmission of communications through an Electronic
System. “Communications” means, collectively, any notice, demand, communication,
information, document or other material provided by or on behalf of any Loan
Party pursuant to any Loan Document or the transactions contemplated therein
which is distributed by the Administrative Agent, any Lender or the Issuing Bank
by means of electronic communications pursuant to this Section, including
through an Electronic System.

SECTION 9.02. 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 a right or power,
or any abandonment or discontinuance of steps to enforce such 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 any other Loan Document are cumulative
and are not exclusive of any rights or remedies that they would otherwise have.
No waiver of any provision of any Loan Document or consent to any departure by
any Loan Party therefrom shall in any event be effective unless the same shall
be permitted by paragraph (b) of this Section, and then such waiver or consent
shall be effec-tive 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.

(b)    Except as provided in the first sentence of Section 2.09(f) (with respect
to any commitment increase), neither this Agreement nor any other Loan Document
nor any provision hereof or thereof may be waived, amended or modified except
(x) in the case of this Agreement, pursuant to an agreement or agreements in
writing entered into by the Borrowers and the Required Lenders or (y) in the
case of any other Loan Document, pursuant to an agreement or agreements in
writing entered into by the Administrative Agent and the Loan Party or Loan
Parties that are parties thereto, with the consent of the Required Lenders;
provided that no such agreement shall (i) increase the Commitment of any Lender
without the written consent of such Lender (including any such Lender that is a
Defaulting Lender), (ii)

76

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

reduce or forgive the principal amount of any Loan or LC Disbursement or reduce
the rate of interest thereon, or reduce or forgive any interest or fees payable
hereunder, without the written consent of each Lender (including any such Lender
that is a Defaulting Lender) directly affected thereby, (iii) postpone any
scheduled date of payment of the principal amount of any Loan or LC
Disbursement, or any date for the payment of any interest, fees or other
Obligations payable hereunder, or reduce the amount of, waive or excuse any such
payment, or postpone the scheduled date of expiration of any Commitment, without
the written consent of each Lender (including any such Lender that is a
Defaulting Lender) directly affected thereby, (iv) change Section 2.18(b) or (d)
in a manner that would alter the manner in which payments are shared, without
the written consent of each Lender (other than any Defaulting Lender), (v)
increase the advance rates set forth in the definition of Borrowing Base or add
new categories of eligible assets, without the written consent of each Lender
(other than any Defaulting Lender), (vi) change any of the provisions of this
Section or the definition of “Required Lenders” or any other provision of any
Loan Document specifying the number or percentage of Lenders (or Lenders of any
Class) required to waive, amend or modify any rights thereunder or make any
determination or grant any consent thereunder, without the written consent of
each Lender (other than any Defaulting Lender), (vii) change Section 2.20,
without the consent of each Lender (other than any Defaulting Lender), (viii)
release any Loan Guarantor from its obligation under its Loan Guaranty (except
as otherwise permitted herein or in the other Loan Documents), without the
written consent of each Lender (other than any Defaulting Lender), or (ix)
except as provided in clause (c) of this Section or in any Collateral Document,
release all or substantially all of the Collateral, without the written consent
of each Lender (other than any Defaulting Lender); provided further that no such
agreement shall amend, modify or otherwise affect the rights or duties of the
Administrative Agent, the Issuing Bank or the Swingline Lender hereunder without
the prior written consent of the Administrative Agent, the Issuing Bank or the
Swingline Lender, as the case may be (it being understood that any change to
Section 2.20 shall require the consent of the Administrative Agent, the Issuing
Bank and the Swingline Lender). The Administrative Agent may also amend the
Commitment Schedule to reflect assignments entered into pursuant to Section
9.04.

(c)    The Lenders and the Issuing Bank hereby irrevocably authorize the
Administrative Agent, at its option and in its sole discretion, to release any
Liens granted to the Administrative Agent by the Loan Parties on any Collateral
(i) upon the termination of the Commitments, payment and satisfaction in full in
cash of all Secured Obligations (other than Unliquidated Obligations), and the
cash collateralization of all Unliquidated Obligations in a manner satisfactory
to each affected Lender, (ii) constituting property being sold or disposed of if
the Loan Party disposing of such property certifies to the Administrative Agent
that the sale or disposition is made in compliance with the terms of this
Agreement (and the Administrative Agent may rely conclusively on any such
certificate, without further inquiry), and to the extent that the property being
sold or disposed of constitutes 100% of the Equity Interest of a Subsidiary, the
Administrative Agent is authorized to release any Loan Guaranty provided by such
Subsidiary, (iii) constituting property leased to a Loan Party under a lease
which has expired or been terminated in a transaction permitted under this
Agreement, or (iv) as required to effect any sale or other disposition of such
Collateral in connection with any exercise of remedies of the Administrative
Agent and the Lenders pursuant to Article VII. Except as provided in the
preceding sentence, the Administrative Agent will not release any Liens on
Collateral without the prior written authorization of the Required Lenders;
provided that, the Administrative Agent may in its discretion, release its Liens
on Collateral valued in the aggregate not in excess of $2,500,000 during any
calendar year without the prior written authorization of the Required Lenders
(it being agreed that the Administrative Agent may rely conclusively on one or
more certificates of the Borrowers as to the value of any Collateral to be so
released, without further inquiry). Any such release shall not in any manner
discharge, affect, or impair the Obligations or any Liens (other than those
expressly being released) upon (or obligations of the Loan Parties in respect
of) all interests retained by the Loan Parties, including the proceeds of any
sale, all of which shall continue to constitute part of the Collateral. Any
execution and delivery by the Administrative Agent of documents in connection
with any such release shall be without recourse to or warranty by the
Administrative Agent.

(d)    If, in connection with any proposed amendment, waiver or consent
requiring the consent of “each Lender” or “each Lender affected thereby,” the
consent of the Required Lenders is obtained, but the consent of other necessary
Lenders is not obtained (any such Lender whose consent is necessary but not
obtained being referred to herein as a “Non-Consenting Lender”), then the
Borrowers may elect to replace a Non-Consenting Lender as a Lender party to this
Agreement, provided that, concurrently with such replacement, (i) another bank
or other entity which is reasonably satisfactory to the Borrowers and the
Administrative Agent shall agree, as of such date, to purchase for

77

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

cash the Loans and other Obligations due to the Non-Consenting Lender pursuant
to an Assignment and Assumption and to become a Lender for all purposes under
this Agreement and to assume all obligations of the Non-Consenting Lender to be
terminated as of such date and to comply with the requirements of clause (b) of
Section 9.04, and (ii) the Borrowers shall pay to such Non-Consenting Lender in
same day funds on the day of such replacement (1) all interest, fees and other
amounts then accrued but unpaid to such Non-Consenting Lender by the Borrowers
hereunder to and including the date of termination, including without limitation
payments due to such Non-Consenting Lender under Sections 2.15 and 2.17, and (2)
an amount, if any, equal to the payment which would have been due to such Lender
on the day of such replacement under Section 2.16 had the Loans of such
Non-Consenting Lender been prepaid on such date rather than sold to the
replacement Lender.

(e)    Notwithstanding anything to the contrary herein, the Administrative Agent
may, with the consent of the Borrower Representative only, amend, modify or
supplement this Agreement or any of the other Loan Documents to cure any
ambiguity, omission, mistake, defect or inconsistency.

SECTION 9.03. Expenses; Indemnity; Damage Waiver. (a)  The Loan Parties shall,
jointly and severally, pay (i) all reasonable out‑of‑pocket expenses incurred by
the Administrative Agent and its Affiliates, including the reasonable fees,
charges and disbursements of one counsel for the Administrative Agent (and
additional local counsel as necessary), in connection with the syndication and
distribution (including, without limitation, via the internet or through a
service such as Intralinks) of the credit facilities provided for herein, the
preparation and administration of the Loan Documents or any amendments,
modifications or waivers of the provi-sions of the Loan Documents (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 Administrative Agent, the Issuing Bank or any Lender, including the fees,
charges and disbursements of any counsel for the Administrative Agent, the
Issuing Bank or any Lender, in connection with the enforcement, collection or
protection of its rights in connection with the Loan Documents, including its
rights under this Section, or in connection with the Loans made or Letters of
Credit issued hereunder, including all such out-of‑pocket expenses incurred
during any workout, restructuring or negotiations in respect of such Loans or
Letters of Credit. Expenses being reimbursed by the Loan Parties under this
Section include, without limiting the generality of the foregoing, fees, costs
and expenses incurred in connection with:

(i)appraisals (subject to the limitations contained in Section 5.12) and
insurance reviews;

(ii)field examinations and the preparation of Reports based on the fees charged
by a third party retained by the Administrative Agent or the internally
allocated fees for each Person employed by the Administrative Agent with respect
to each field examination; provided, that, unless a Default shall have occurred
and be continuing, the Borrowers will reimburse such costs and expenses for up
to two such field examinations per calendar year;

(iii)    background checks regarding senior management and/or key investors, as
deemed necessary or appropriate in the sole discretion of the Administrative
Agent;

(iv)    Taxes, fees and other charges for (A) lien and title searches and title
insurance (if applicable) and (B) filing financing statements and continuations,
and other actions to perfect, protect, and continue the Administrative Agent’s
Liens;

(v)    sums paid or incurred to take any action required of any Loan Party under
the Loan Documents that such Loan Party fails to pay or take;

(vi)    forwarding loan proceeds, and, to the extent applicable, collecting
checks and other items of payment, and establishing and maintaining the accounts
and lock boxes, and costs; and

(vii)    expenses of preserving and protecting the Collateral.

78

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

All of the foregoing fees, costs and expenses may be charged to the Borrowers as
Revolving Loans or to another deposit account, all as described in
Section 2.18(c).

(b)    The Loan Parties shall, jointly and severally, indemnify the
Administrative Agent, the Issuing Bank 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, penalties, incremental taxes, 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 the Loan Documents or
any agreement or instrument contemplated thereby, the performance by the parties
hereto of their respective obligations thereunder 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 a
Loan Party or a Subsidiary, or any Environmental Liability related in any way to
a Loan Party or a Subsidiary, (iv) the failure of a Loan Party to deliver to the
Administrative Agent the required receipts or other required documentary
evidence with respect to a payment made by a Loan Party for Taxes pursuant to
Section 2.17, or (v) 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, penalties, liabilities or related
expenses are determined by a court of competent jurisdiction by final and
nonappealable judgment to have resulted from the gross negligence or wilful
misconduct of such Indemnitee. WITHOUT LIMITATION OF THE FOREGOING, IT IS THE
INTENTION OF THE LOAN PARTIES AND THE LOAN PARTIES AGREE THAT THE FOREGOING
INDEMNITIES SHALL APPLY TO EACH INDEMNITEE WITH RESPECT TO LOSSES, CLAIMS,
DAMAGES, PENALTIES, LIABILITIES AND RELATED EXPENSES (INCLUDING, WITHOUT
LIMITATION, ALL EXPENSES OF LITIGATION OR PREPARATION THEREFOR), WHICH IN WHOLE
OR IN PART ARE CAUSED BY OR ARISE OUT OF THE NEGLIGENCE OF SUCH (AND/OR ANY
OTHER) INDEMNITEE. This Section 9.03(b) shall not apply with respect to Taxes
other than any Taxes that represent losses or damages arising from any non-Tax
claim.

(c)    To the extent that the Loan Parties fail to pay any amount required to be
paid by it to the Administrative Agent, the Issuing Bank or the Swingline Lender
under paragraph (a) or (b) of this Section, each Lender severally agrees to pay
to the Administrative Agent, the Issuing Bank or the Swingline Lender, as the
case may be, such Lender’s Applicable Percentage (determined as of the time that
the applicable unreimbursed expense or indemnity payment is sought) of such
unpaid amount (it being understood that the payment by any Lender of any such
amount shall not relieve such Loan Party of any default in the payment thereof);
provided that the unreimbursed expense or indemnified loss, claim, damage,
penalty, liability or related expense, as the case may be, was incurred by or
asserted against the Administrative Agent, the Issuing Bank or the Swingline
Lender in its capacity as such.

(d)    To the extent permitted by applicable law, no party hereto shall assert,
and each such party hereby waives, any claim against any other party hereto (i)
for any damages arising from the use by others of information or other materials
obtained through telecommunications, electronic or other information
transmission systems (including the Internet) or (ii) 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, any other Loan Document or any agreement or instrument
contemplated hereby, the Transactions, any Loan or Letter of Credit or the use
of the proceeds thereof; provided that, nothing in this paragraph (d) shall
relieve any Loan Party of any obligation it may have to indemnify an Indemnitee
against special, indirect, consequential or punitive damages asserted against
such Indemnitee by a third party.

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

SECTION 9.04. 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 (i) no Borrower
may assign or otherwise

79

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

transfer any of its rights or obligations hereunder without the prior written
consent of each Lender (and any attempted assignment or transfer by any Borrower
without such consent shall be null and void) and (ii) no Lender may assign or
otherwise transfer its rights or obligations hereunder except in accordance with
this Section. 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), Participants (to the extent
provided in paragraph (c) of this Section) 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)(i)    Subject to the conditions set forth in paragraph (b)(ii) below, any
Lender may assign to one or more Persons (other than an Ineligible Institution)
all or a portion of its rights and obligations under this Agreement (including
all or a portion of its Commitment and the Loans at the time owing to it) with
the prior written consent (such consent not to be unreasonably withheld) of:

(A)    the Borrower Representative, provided that the Borrower Representative
shall be deemed to have consented to any such assignment unless it shall object
thereto by written notice to the Administrative Agent within five (5) Business
Days after having received notice thereof, and provided further that no consent
of the Borrower Representative shall be required for an assignment to a Lender,
an Affiliate of a Lender, an Approved Fund or, if an Event of Default has
occurred and is continuing, any other assignee; 

(B)    the Administrative Agent;

(C)    the Issuing Bank; and

(D)    the Swingline Lender.

(ii)    Assignments shall be subject to the following additional conditions:

(A)    except in the case of an assignment to a Lender or an Affiliate of a
Lender or an Approved Fund or an assignment of the entire remaining amount of
the assigning Lender’s Commitment or Loans of any Class, the amount of the
Commitment or Loans of the assigning Lender subject to each such assignment
(determined as of the date the Assignment and Assumption with respect to such
assignment is delivered to the Administrative Agent) shall not be less than
$5,000,000 unless each of the Borrower Representative and the Administrative
Agent otherwise consent, provided that no such consent of the Borrower
Representative shall be required if an Event of Default has occurred and is
continuing;

(B)    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;

(C)    the parties to each assignment shall execute and deliver to the
Administrative Agent an Assignment and Assumption, together with a processing
and recordation fee of $3,500 payable by the assignor and assignee; and

(D)    the assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire in which the assignee
designates one or more credit contacts to whom all syndicate-level information
(which may contain material non-public information about Compressco Partners,
the other Loan Parties and their Related Parties or their respective securities)
will be made available and who may receive such information in accordance with
the assignee’s compliance procedures and applicable laws, including Federal and
state securities laws.

For the purposes of this Section 9.04(b), the terms “Approved Fund” and
“Ineligible Institution” have the following meanings:

80

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

“Approved Fund” means any Person (other than a natural person) that is engaged
in making, purchasing, holding or investing in bank loans and similar extensions
of credit in the ordinary course of its business and that is administered or
managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an
Affiliate of an entity that administers or manages a Lender.

“Ineligible Institution” means a (a) natural person, (b) a Defaulting Lender,
(c) a holding company, investment vehicle or trust for, or owned and operated
for the primary benefit of, a natural person or relative(s) thereof; provided
that, such holding company, investment vehicle or trust shall not constitute an
Ineligible Institution if it (x) has not been established for the primary
purpose of acquiring any Loans or Commitments, (y) is managed by a professional
advisor, who is not such natural person or a relative thereof, having
significant experience in the business of making or purchasing commercial loans,
and (z) has assets greater than $25,000,000 and a significant part of its
activities consist of making or purchasing commercial loans and similar
extensions of credit in the ordinary course of its business or (d) a Loan Party
or a Subsidiary or other Affiliate of a Loan Party.

(iii)    Subject to acceptance and recording thereof pursuant to
paragraph (b)(iv) of this Section, from and after the effective date specified
in each Assignment and Assumption, the assignee thereunder shall be a party
hereto and, to the extent of the interest assigned by such Assignment and
Assumption, 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 Assumption, be released from its obliga-tions
under this Agreement (and, in the case of an Assignment and Assumption covering
all of the assigning Lender’s rights and obligations under this Agreement, 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 and 9.03). Any assignment or transfer by a
Lender of rights or obligations under this Agreement that does not comply with
this Section 9.04 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 (c) of this Section.

(iv)    The Administrative Agent, acting for this purpose as a non-fiduciary
agent of the Borrowers, shall maintain at one of its offices a copy of each
Assignment and Assumption delivered to it and a register for the recordation of
the names and addresses of the Lenders, and the Commitment of, and principal
amount of the Loans and LC Disbursements owing to, each Lender pursuant to the
terms hereof from time to time (the “Register”). The entries in the Register
shall be conclusive, and the Borrowers, the Administrative Agent, the Issuing
Bank and the Lenders shall 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, notwithstanding notice to the contrary. The Register shall be
available for inspection by the Borrowers, the Issuing Bank and any Lender, at
any reasonable time and from time to time upon reasonable prior notice.

(v)    Upon its receipt of a duly completed Assignment and Assumption 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 and
any written consent to such assignment required by paragraph (b) of this
Section, the Administrative Agent shall accept such Assignment and Assumption
and record the information contained therein in the Register; provided that if
either the assigning Lender or the assignee shall have failed to make any
payment required to be made by it pursuant to Section 2.05, 2.06(d) or (e),
2.07(b), 2.18(d) or 9.03(c), the Administrative Agent shall have no obligation
to accept such Assignment and Assumption and record the information therein in
the Register unless and until such payment shall have been made in full,
together with all accrued interest thereon. No assignment shall be effective for
purposes of this Agreement unless it has been recorded in the Register as
provided in this paragraph.

(c) Any Lender may, without the consent of the Borrowers, the Administrative
Agent, the Issuing Bank or the Swingline Lender, sell participations to one or
more banks or other entities (a “Participant”) other than an Ineligible
Institution in all or a portion of such Lender’s rights and obligations under
this Agreement (including all or a portion of its Commitment and the Loans owing
to it); provided that (A) such Lender’s obligations under this Agreement shall
remain unchanged; (B) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations; and (C) the Borrowers,
the Administrative Agent, the Issuing Bank and the other Lenders shall continue
to deal solely and directly with such Lender in connection with such Lender’s
rights and obligations under this Agreement. Any agreement or instrument
pursuant to which a Lender sells such a participation shall provide that

81

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

such Lender shall retain the sole right to enforce this Agreement and to approve
any amendment, modification or waiver of any provision of this Agreement;
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 9.02(b) that
affects such Participant. The Borrowers agree that each Participant shall be
entitled to the benefits of Sections 2.15, 2.16 and 2.17 (subject to the
requirements and limitations therein, including the requirements under
Section 2.17(f) and (g) (it being understood that the documentation required
under Section 2.17(f) shall be delivered to the participating Lender and the
information and documentation required under Section 2.17(g) will be delivered
to the Borrowers and the Administrative Agent)) to the same extent as if it were
a Lender and had acquired its interest by assignment pursuant to paragraph (b)
of this Section; provided that such Participant (A) agrees to be subject to the
provisions of Sections 2.18 and 2.19 as if it were an assignee under
paragraph (b) of this Section; and (B) shall not be entitled to receive any
greater payment under Section 2.15 or 2.17, with respect to any participation,
than its participating Lender would have been entitled to receive, except to the
extent such entitlement to receive a greater payment results from a Change in
Law that occurs after the Participant acquired the applicable participation.

Each Lender that sells a participation agrees, at the Borrowers’ request and
expense, to use reasonable efforts to cooperate with the Borrowers to effectuate
the provisions of Section 2.19(b) with respect to any Participant. To the extent
permitted by law, each Participant also shall be entitled to the benefits of
Section 9.08 as though it were a Lender, provided such Participant agrees to be
subject to Section 2.18(c) as though it were a Lender. Each Lender that sells a
participation shall, acting solely for this purpose as an agent of the
Borrowers, maintain a register on which it enters the name and address of each
Participant and the principal amounts (and stated interest) of each
Participant’s interest in the Loans or other obligations under this Agreement or
any other Loan Document (the “Participant Register”); provided that no Lender
shall have any obligation to disclose all or any portion of the Participant
Register (including the identity of any Participant or any information relating
to a Participant’s interest in any Commitments, Loans, Letters of Credit or its
other obligations under any Loan Document) to any Person except to the extent
that such disclosure is necessary to establish that such Commitment, Loan,
Letter of Credit or other obligation is in registered form under Section
5f.103-1(c) of the United States Treasury Regulations. The entries in the
Participant Register shall be conclusive absent manifest error, and such Lender
shall treat each Person whose name is recorded in the Participant Register as
the owner of such participation for all purposes of this Agreement
notwithstanding any notice to the contrary. For the avoidance of doubt, the
Administrative Agent (in its capacity as Administrative Agent) shall have no
responsibility for maintaining a Participant Register.

(d)    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 without limitation 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 9.05. Survival. All covenants, agreements, representations and
warranties made by the Loan Parties in the Loan Documents and in the
certificates or other instru-ments 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 the 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 the Administrative Agent, the Issuing
Bank 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 outstand-ing and unpaid or any Letter of Credit is outstanding and
so long as the Commitments have not expired or terminated. The provisions of
Sections 2.15, 2.16, 2.17 and 9.03 and Article VIII shall survive and remain in
full force and effect regardless of the consummation of the transactions
contemplated hereby, the repayment of the Loans, the expiration or termination
of the Letters of Credit and the Commitments or the termination of this
Agreement or any other Loan Document or any provision hereof or thereof.

SECTION 9.06. Counterparts; Integration; Effectiveness; Electronic Execution.
(a) 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, the other Loan

82

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

Documents and any separate letter agreements with respect to fees payable to the
Administrative Agent constitute the entire contract among the parties relating
to the subject matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof. Except
as provided in Section 4.01, 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.

(b) Delivery of an executed counterpart of a signature page of this Agreement by
telecopy, emailed pdf. or any other electronic means that reproduces an image of
the actual executed signature page shall be effective as delivery of a manually
executed counterpart of this Agreement. The words “execution,” “signed,”
“signature,” “delivery,” and words of like import in or relating to any document
to be signed in connection with this Agreement and the transactions contemplated
hereby or thereby shall be deemed to include Electronic Signatures, deliveries
or the keeping of records in electronic form, each of which shall be of the same
legal effect, validity or enforceability as a manually executed signature,
physical delivery thereof or the use of a paper-based recordkeeping system, as
the case may be, to the extent and as provided for in any applicable law,
including the Federal Electronic Signatures in Global and National Commerce Act,
the New York State Electronic Signatures and Records Act, or any other similar
state laws based on the Uniform Electronic Transactions Act. THIS WRITTEN
AGREEMENT REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.

SECTION 9.07. Severability. Any provision of any Loan Document 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 thereof; and the invalidity of a particular provision
in a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

SECTION 9.08. 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 Borrowers or any
Loan Guarantor against any of and all the Secured Obligations held by such
Lender, irrespective of whether or not such Lender shall have made any demand
under the Loan Documents and although such obligations may be unmatured. The
applicable Lender shall notify the Borrower Representative and the
Administrative Agent of such set-off or application, provided that any failure
to give or any delay in giving such notice shall not affect the validity of any
such set-off or application under this Section. 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 9.09. Governing Law; Jurisdiction; Consent to Service of Process. (a)
The Loan Documents (other than those containing a contrary express choice of law
provision) shall be governed by and construed in accordance with the internal
laws (and not the law of conflicts) of the State of Texas, but giving effect to
federal laws applicable to national banks.

(b)    Each Loan Party hereby irrevocably and unconditionally submits, for
itself and its property, to the exclusive jurisdiction of any U.S. Federal or
Texas State court sitting in Houston, Texas in any action or proceeding arising
out of or relating to any Loan Documents, 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
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
or any other Loan Document against any Loan Party or its proper-ties in the
courts of any jurisdiction.
 

83

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

(c)    Each Loan Party hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or here-after 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. 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 9.01. 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 9.10. 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 OR THEREBY (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 AGREE-MENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS IN THIS SECTION.

SECTION 9.11. 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 9.12. Confidentiality. Each of the Administrative Agent, 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 (including any self-regulatory
authority, such as the National Association of Insurance Commissioners), (c) to
the extent required by any Requirement of Law 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 under this Agreement or any other Loan Document or
any suit, action or proceeding relating to this Agreement or any other Loan
Document or the enforcement of rights hereunder or thereunder, (f) subject to an
agreement containing provisions substantially the same as those of this Section,
to (i) any assignee of or Participant in, or any prospective assignee of or
Participant in, any of its rights or obligations under this Agreement or (ii)
any actual or prospective counterparty (or its advisors) to any swap or
derivative transaction relating to the Loan Parties and their obligations, (g)
with the consent of the Borrower Representative or (h) to the extent such
Information (i) becomes publicly available other than as a result of a breach of
this Section or (ii) becomes available to the Administrative Agent, the Issuing
Bank or any Lender on a non-confidential basis from a source other than the
Borrowers. For the purposes of this Section, “Information” means all information
received from the Borrowers relating to the Borrowers or their 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 Borrowers; provided that, in the case of information received from the
Borrowers 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.

EACH LENDER ACKNOWLEDGES THAT INFORMATION AS DEFINED IN SECTION 9.12 FURNISHED
TO IT PURSUANT TO THIS AGREEMENT MAY INCLUDE MATERIAL NON-PUBLIC INFORMATION
CONCERNING THE COMPANY, AND ITS AFFILIATES AND THEIR RELATED PARTIES OR THEIR
RESPECTIVE SECURITIES, AND CONFIRMS THAT IT HAS DEVELOPED COMPLIANCE PROCEDURES
REGARDING THE USE OF MATERIAL NON-PUBLIC INFORMATION

84

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

AND THAT IT WILL HANDLE SUCH MATERIAL NON-PUBLIC INFORMATION IN ACCORDANCE WITH
THOSE PROCEDURES AND APPLICABLE LAW, INCLUDING FEDERAL AND STATE SECURITIES
LAWS.

ALL INFORMATION, INCLUDING REQUESTS FOR WAIVERS AND AMENDMENTS, FURNISHED BY THE
BORROWERS OR THE ADMINISTRATIVE AGENT PURSUANT TO, OR IN THE COURSE OF
ADMINISTERING, THIS AGREEMENT WILL BE SYNDICATE-LEVEL INFORMATION, WHICH MAY
CONTAIN MATERIAL NON-PUBLIC INFORMATION ABOUT THE COMPANY, THE LOAN PARTIES AND
THEIR RELATED PARTIES OR THEIR RESPECTIVE SECURITIES. ACCORDINGLY, EACH LENDER
REPRESENTS TO THE BORROWERS AND THE ADMINISTRATIVE AGENT THAT IT HAS IDENTIFIED
IN ITS ADMINISTRATIVE QUESTIONNAIRE A CREDIT CONTACT WHO MAY RECEIVE INFORMATION
THAT MAY CONTAIN MATERIAL NON-PUBLIC INFORMATION IN ACCORDANCE WITH ITS
COMPLIANCE PROCEDURES AND APPLICABLE LAW, INCLUDING FEDERAL AND STATE SECURITIES
LAWS.

SECTION 9.13. Several Obligations; Nonreliance; Violation of Law. The respective
obligations of the Lenders hereunder are several and not joint and the failure
of any Lender to make any Loan or perform any of its obligations hereunder shall
not relieve any other Lender from any of its obligations hereunder. Each Lender
hereby represents that it is not relying on or looking to any margin stock for
the repayment of the Borrowings provided for herein. Anything contained in this
Agreement to the contrary notwithstanding, neither the Issuing Bank nor any
Lender shall be obligated to extend credit to the Borrowers in violation of any
Requirement of Law.

SECTION 9.14. USA PATRIOT Act. Each Lender that is subject to the requirements
of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26,
2001)) (the “Act”) hereby notifies each Loan Party that pursuant to the
requirements of the Act, it is required to obtain, verify and record information
that identifies such Loan Party, which information includes the name and address
of such Loan Party and other information that will allow such Lender to identify
such Loan Party in accordance with the Act.

SECTION 9.15. Disclosure. Each Loan Party and each Lender hereby acknowledges
and agrees that the Administrative Agent and/or its Affiliates from time to time
may hold investments in, make other loans to or have other relationships with
any of the Loan Parties and their respective Affiliates.
         
SECTION 9.16. Appointment for Perfection. Each Lender hereby appoints each other
Lender as its agent for the purpose of perfecting Liens, for the benefit of the
Administrative Agent and the other Secured Parties, in assets which, in
accordance with Article 9 of the UCC or any other applicable law can be
perfected only by possession or control. Should any Lender (other than the
Administrative Agent) obtain possession or control of any such Collateral, such
Lender shall notify the Administrative Agent thereof, and, promptly upon the
Administrative Agent’s request therefor shall deliver such Collateral to the
Administrative Agent or otherwise deal with such Collateral in accordance with
the Administrative Agent’s instructions.

SECTION 9.17. Interest Rate Limitation. Notwithstanding anything herein to the
contrary, if at any time the interest rate applicable to any Loan, together with
all fees, charges and other amounts which are treated as interest on such Loan
under appli-cable law (collectively the “Charges”), shall exceed the maximum
non-usurious lawful rate (the “Maximum Rate”) which may be contracted for,
charged, taken, received or reserved by the Lender holding such Loan in
accordance with applicable law, the rate of interest payable in respect of such
Loan hereunder, together with all Charges payable in respect thereof, shall be
limited to the Maximum Rate and, to the extent lawful, the interest and Charges
that would have been payable in respect of such Loan but were not payable as a
result of the operation of this Section shall be cumulated and the interest and
Charges payable to such Lender in respect of other Loans or periods shall be
increased (but not above the Maximum Rate therefor) until such cumulated amount,
together with interest thereon at the Federal Funds Effective Rate to the date
of repayment, shall have been received by such Lender.

SECTION 9.18. No Advisory or Fiduciary Responsibility. In connection with all
aspects of each transaction contemplated hereby (including in connection with
any amendment, waiver or other modification hereof or of any other Loan
Document), each Borrower acknowledges and agrees that: (i) (A) the arranging and
other services regarding

85

between such Borrower and its Affiliates, on the one hand, and the Lenders and
their Affiliates, on the other hand, (B) such Borrower has consulted its own
legal, accounting, regulatory and tax advisors to the extent it has deemed
appropriate, and (C) such Borrower is capable of evaluating, and understands and
accepts, the terms, risks and conditions of the transactions contemplated hereby
and by the other Loan Documents; (ii) (A) each of the Lenders and their
Affiliates is and has been acting solely as a principal and, except as expressly
agreed in writing by the relevant parties, has not been, is not, and will not be
acting as an advisor, agent or fiduciary for such Borrower or any of its
Affiliates, or any other Person and (B) no Lender or any of its Affiliates has
any obligation to such Borrower or any of its Affiliates with respect to the
transactions contemplated hereby except, in the case of a Lender, those
obligations expressly set forth herein and in the other Loan Documents; and
(iii) each of the Lenders and their respective Affiliates may be engaged in a
broad range of transactions that involve interests that differ from those of
such Borrower and its Affiliates, and no Lender or any of its Affiliates has any
obligation to disclose any of such interests to such Borrower or its Affiliates.
To the fullest extent permitted by law, each Borrower hereby waives and releases
any claims that it may have against each of the Lenders and their Affiliates
with respect to any breach or alleged breach of agency or fiduciary duty in
connection with any aspect of any transaction contemplated hereby.

SECTION 9.19. Limitation of Liability. Compressco GP, as general partner of
Compressco Partners, shall not be liable for the obligations of any Loan Party
under this Agreement or any other Loan Document, including, without limitation,
by reason of any payment obligation imposed by governing state partnership
statutes and any provision of the applicable limited partnership agreement of
Compressco Partners or any other Loan Party that requires Compressco GP to
restore a capital account deficit; provided that nothing in this Section 9.19
shall be construed so as to prevent the Administrative Agent or any Lender from
commencing any action, suit or proceeding with respect to or causing legal
papers to be served upon Compressco GP for the purpose of (a) obtaining
jurisdiction over Compressco Partners or (b) obtaining any judgment, order or
execution against Compressco GP arising out of any fraud or intentional
misrepresentation by Compressco GP in connection with the Loan Documents or in
order to recover moneys received by Compressco GP in violation of the terms of
this Agreement.

SECTION 9.20. Authorization to Distribute Certain Materials to Public-Siders.

(a) If the Borrowers do not file this Agreement with the SEC, then the Borrowers
hereby authorize the Administrative Agent to distribute the execution version of
this Agreement and the Loan Documents to all Lenders, including their
Public-Siders. Each Borrower acknowledges its understanding that Public-Siders
and their firms may be trading in any of the Loan Parties’ respective securities
while in possession of the Loan Documents.

(b) Each Borrower represents and warrants that none of the information in the
Loan Documents constitutes or contains material non-public information within

hereof, each Borrower agrees that it will promptly make such information
publicly available by press release or public filing with the SEC.

(c) If any Borrower issues any 144A Securities during the term of this Agreement
and its financial statements are not filed with the SEC, such Borrower (i)

financial statements and Supplemental Materials and (ii) represents, warrants
and agrees that the financial statements and Supplemental Materials will not
constitute information that, upon disclosure to Public-Siders, would restrict
them or their firms from purchasing or selling any of the 144A Securities under
U.S. federal and state securities laws. The Borrowers further agree to clearly
label such financial statements and/or Supplemental Materials with a notice
stating: “Confidential Financial Statements provided to 144A Holders” or
“Confidential Supplemental Materials,” as the case may, before delivering them
to the Administrative Agent.

(d) Each Borrower acknowledges its understanding that Public-Siders and their
firms may be trading in any of the Loan Parties’ respective securities while in
possession of the materials, documents and information distributed to them

ARTICLE X

Loan Guaranty

SECTION 10.01. Guaranty. Each Loan Guarantor (other than those that have
delivered a separate Guaranty) hereby agrees that it is jointly and severally
liable for, and, as a primary obligor and not merely as surety, absolutely and
unconditionally guarantees to the Secured Parties, the prompt payment when due,
whether at stated maturity, upon acceleration or otherwise, and at all times
thereafter, of the Secured Obligations and all costs and expenses, including,
without limitation, all court costs and attorneys’ and paralegals’ fees
(including allocated costs of in-house counsel and paralegals) and expenses paid
or incurred by the Administrative Agent, the Issuing Bank and the Lenders in
endeavoring to collect all or any part of the Secured Obligations from, or in
prosecuting any action against, any Borrower, any Loan Guarantor or any other
guarantor of all or any part of the Secured Obligations (such costs and
expenses, together with the Secured Obligations, collectively the “Guaranteed
Obligations”; provided, however, that the definition of “Guaranteed Obligations”
shall not create any guarantee by any Loan Guarantor of (or grant of security
interest by any Loan Guarantor to support, as applicable) any Excluded Swap
Obligations of such Loan Guarantor for purposes of determining any obligations
of any Loan Guarantor). Each Loan Guarantor further agrees that the Guaranteed
Obligations may be extended or renewed in whole or in part without notice to or
further assent from it, and that it remains bound upon its guarantee
notwithstanding any such extension or renewal. All terms of this Loan Guaranty
apply to and may be enforced by or on behalf of any domestic or foreign branch
or Affiliate of any Lender that extended any portion of the Guaranteed
Obligations.

SECTION 10.02. Guaranty of Payment. This Loan Guaranty is a guaranty of payment
and not of collection. Each Loan Guarantor waives any right to require the
Administrative Agent, the Issuing Bank or any Lender to sue any Borrower, any
Loan Guarantor, any other guarantor of, or any other Person obligated for, all
or any part of the Guaranteed Obligations (each, an “Obligated Party”), or
otherwise to enforce its payment against any collateral securing all or any part
of the Guaranteed Obligations.

SECTION 10.03. No Discharge or Diminishment of Loan Guaranty. (a) Except as
otherwise provided for herein, the obligations of each Loan Guarantor hereunder
are unconditional and absolute and not subject to any reduction, limitation,
impairment or termination for any reason (other than the indefeasible payment in
full in cash of the Guaranteed Obligations), including: (i) any claim of waiver,
release, extension, renewal, settlement, surrender, alteration or compromise of
any of the Guaranteed Obligations, by operation of law or otherwise; (ii) any
change in the corporate existence, structure or ownership of any Borrower or any
other Obligated Party liable for any of the Guaranteed Obligations; (iii) any
insolvency, bankruptcy, reorganization or other similar proceeding affecting any
Obligated Party or their assets or any resulting release or discharge of any
obligation of any Obligated Party; or (iv) the existence of any claim, setoff or
other rights which any Loan Guarantor may have at any time against any Obligated
Party, the Administrative Agent, the Issuing Bank, any Lender or any other
Person, whether in connection herewith or in any unrelated transactions.

(b)    The obligations of each Loan Guarantor hereunder are not subject to any
defense or setoff, counterclaim, recoupment or termination whatsoever by reason
of the invalidity, illegality or unenforceability of any of the Guaranteed
Obligations or otherwise, or any provision of applicable law or regulation
purporting to prohibit payment by any Obligated Party, of the Guaranteed
Obligations or any part thereof.

(c)    Further, the obligations of any Loan Guarantor hereunder are not
discharged or impaired or otherwise affected by: (i) the failure of the
Administrative Agent, the Issuing Bank or any Lender to assert any claim or
demand or to enforce any remedy with respect to all or any part of the
Guaranteed Obligations; (ii) any waiver or modification of or supplement to any
provision of any agreement relating to the Guaranteed Obligations; (iii) any
release, non-perfection or invalidity of any indirect or direct security for the
obligations of any Borrower for all or any part of the Guaranteed Obligations or
any obligations of any other Obligated Party liable for any of the Guaranteed
Obligations; (iv) any action or failure to act by the Administrative Agent, the
Issuing Bank or any Lender with respect to any collateral securing any part of
the Guaranteed Obligations; or (v) any default, failure or delay, willful or
otherwise, in

87

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

the payment or performance of any of the Guaranteed Obligations, or any other
circumstance, act, omission or delay that might in any manner or to any extent
vary the risk of such Loan Guarantor or that would otherwise operate as a
discharge of any Loan Guarantor as a matter of law or equity (other than the
indefeasible payment in full in cash of the Guaranteed Obligations).

SECTION 10.04. Defenses Waived. To the fullest extent permitted by applicable
law, each Loan Guarantor hereby waives any defense based on or arising out of
any defense of any Borrower or any Loan Guarantor or the unenforceability of all
or any part of the Guaranteed Obligations from any cause, or the cessation from
any cause of the liability of any Borrower, any Loan Guarantor or any other
Obligated Party, other than the indefeasible payment in full in cash of the
Guaranteed Obligations. Without limiting the generality of the foregoing, each
Loan Guarantor irrevocably waives acceptance hereof, presentment, demand,
protest and, to the fullest extent permitted by law, any notice not provided for
herein, as well as any requirement that at any time any action be taken by any
Person against any Obligated Party or any other Person. Each Loan Guarantor
confirms that it is not a surety under any state law and shall not raise any
such law as a defense to its obligations hereunder. The Administrative Agent
may, at its election, foreclose on any Collateral held by it by one or more
judicial or nonjudicial sales, accept an assignment of any such Collateral in
lieu of foreclosure or otherwise act or fail to act with respect to any
collateral securing all or a part of the Guaranteed Obligations, compromise or
adjust any part of the Guaranteed Obligations, make any other accommodation with
any Obligated Party or exercise any other right or remedy available to it
against any Obligated Party, without affecting or impairing in any way the
liability of such Loan Guarantor under this Loan Guaranty except to the extent
the Guaranteed Obligations have been fully and indefeasibly paid in cash. To the
fullest extent permitted by applicable law, each Loan Guarantor waives any
defense arising out of any such election even though that election may operate,
pursuant to applicable law, to impair or extinguish any right of reimbursement
or subrogation or other right or remedy of any Loan Guarantor against any
Obligated Party or any security.

SECTION 10.05. Rights of Subrogation. No Loan Guarantor will assert any right,
claim or cause of action, including, without limitation, a claim of subrogation,
contribution or indemnification, that it has against any Obligated Party or any
collateral, until the Loan Parties and the Loan Guarantors have fully performed
all their obligations to the Administrative Agent, the Issuing Bank and the
Lenders.

SECTION 10.06. Reinstatement; Stay of Acceleration. If at any time any payment
of any portion of the Guaranteed Obligations (including a payment effected
through exercise of a right of setoff) is rescinded, or must otherwise be
restored or returned upon the insolvency, bankruptcy or reorganization of any
Borrower or otherwise (including pursuant to any settlement entered into by a
Secured Party in its discretion), each Loan Guarantor’s obligations under this
Loan Guaranty with respect to that payment shall be reinstated at such time as
though the payment had not been made and whether or not the Administrative
Agent, the Issuing Bank and the Lenders are in possession of this Loan Guaranty.
If acceleration of the time for payment of any of the Guaranteed Obligations is
stayed upon the insolvency, bankruptcy or reorganization of any Borrower, all
such amounts otherwise subject to acceleration under the terms of any agreement
relating to the Guaranteed Obligations shall nonetheless be payable by the Loan
Guarantors forthwith on demand by the Administrative Agent.

SECTION 10.07. Information. Each Loan Guarantor assumes all responsibility for
being and keeping itself informed of the Borrowers’ financial condition and
assets, and of all other circumstances bearing upon the risk of nonpayment of
the Guaranteed Obligations and the nature, scope and extent of the risks that
each Loan Guarantor assumes and incurs under this Loan Guaranty, and agrees that
neither the Administrative Agent, the Issuing Bank nor any Lender shall have any
duty to advise any Loan Guarantor of information known to it regarding those
circumstances or risks.

SECTION 10.08. Termination. Each of the Lenders and the Issuing Bank may
continue to make loans or extend credit to the Borrowers based on this Loan
Guaranty until five (5) days after it receives written notice of termination
from any Loan Guarantor. Notwithstanding receipt of any such notice, each Loan
Guarantor will continue to be liable to the Lenders for any Guaranteed
Obligations created, assumed or committed to prior to the fifth day after
receipt of the notice, and all subsequent renewals, extensions, modifications
and amendments with respect to, or substitutions for, all or any part of such
Guaranteed Obligations. Nothing in this Section 10.08 shall be deemed to
constitute a waiver of, or eliminate, limit, reduce or otherwise impair any
rights or remedies the Administrative Agent

88

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

or any Lender may have in respect of, any Default or Event of Default that may
exist under Article VII hereof as a result of any such notice of termination.

SECTION 10.09. Taxes. Each payment of the Guaranteed Obligations will be made by
each Loan Guarantor without withholding for any Taxes, unless such withholding
is required by law. If any Loan Guarantor determines, in its sole discretion
exercised in good faith, that it is so required to withhold Taxes, then such
Loan Guarantor may so withhold and shall timely pay the full amount of withheld
Taxes to the relevant Governmental Authority in accordance with applicable law.
If such Taxes are Indemnified Taxes, then the amount payable by such Loan
Guarantor shall be increased as necessary so that, net of such withholding
(including such withholding applicable to additional amounts payable under this
Section), the Administrative Agent, Lender or Issuing Bank (as the case may be)
receives the amount it would have received had no such withholding been made.

SECTION 10.10. Maximum Liability. Notwithstanding any other provision of this
Loan Guaranty, the amount guaranteed by each Loan Guarantor hereunder shall be
limited to the extent, if any, required so that its obligations hereunder shall
not be subject to avoidance under Section 548 of the Bankruptcy Code or under
any applicable state Uniform Fraudulent Transfer Act, Uniform Fraudulent
Conveyance Act or similar statute or common law. In determining the limitations,
if any, on the amount of any Loan Guarantor’s obligations hereunder pursuant to
the preceding sentence, it is the intention of the parties hereto that any
rights of subrogation, indemnification or contribution which such Loan Guarantor
may have under this Loan Guaranty, any other agreement or applicable law shall
be taken into account.

SECTION 10.11. Contribution.

(a)To the extent that any Loan Guarantor shall make a payment under this Loan
Guaranty (a “Guarantor Payment”) which, taking into account all other Guarantor
Payments then previously or concurrently made by any other Loan Guarantor,
exceeds the amount which otherwise would have been paid by or attributable to
such Loan Guarantor if each Loan Guarantor had paid the aggregate Guaranteed
Obligations satisfied by such Guarantor Payment in the same proportion as such
Loan Guarantor’s “Allocable Amount” (as defined below) (as determined
immediately prior to such Guarantor Payment) bore to the aggregate Allocable
Amounts of each of the Loan Guarantors as determined immediately prior to the
making of such Guarantor Payment, then, following indefeasible payment in full
in cash of the Guarantor Payment and the Guaranteed Obligations (other than
Unliquidated Obligations that have not yet arisen), and all Commitments and
Letters of Credit have terminated or expired or, in the case of all Letters of
Credit, are fully collateralized on terms reasonably acceptable to the
Administrative Agent and the Issuing Bank, and this Agreement, the Swap
Agreement Obligations and the Banking Services Obligations have terminated, such
Loan Guarantor shall be entitled to receive contribution and indemnification
payments from, and be reimbursed by, each other Loan Guarantor for the amount of
such excess, pro rata based upon their respective Allocable Amounts in effect
immediately prior to such Guarantor Payment.
(b)As of any date of determination, the “Allocable Amount” of any Loan Guarantor
shall be equal to the excess of the fair saleable value of the property of such
Loan Guarantor over the total liabilities of such Loan Guarantor (including the
maximum amount reasonably expected to become due in respect of contingent
liabilities, calculated, without duplication, assuming each other Loan Guarantor
that is also liable for such contingent liability pays its ratable share
thereof), giving effect to all payments made by other Loan Guarantors as of such
date in a manner to maximize the amount of such contributions.
(c)This Section 10.11 is intended only to define the relative rights of the Loan
Guarantors, and nothing set forth in this Section 10.11 is intended to or shall
impair the obligations of the Loan Guarantors, jointly and severally, to pay any
amounts as and when the same shall become due and payable in accordance with the
terms of this Loan Guaranty.
(d)The parties hereto acknowledge that the rights of contribution and
indemnification hereunder shall constitute assets of the Loan Guarantor or Loan
Guarantors to which such contribution and indemnification is owing.

89

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

(e)The rights of the indemnifying Loan Guarantors against other Loan Guarantors
under this Section 10.11 shall be exercisable upon the full and indefeasible
payment of the Guaranteed Obligations in cash (other than Unliquidated
Obligations that have not yet arisen) and the termination or expiry (or, in the
case of all Letters of Credit, full cash collateralization), on terms reasonably
acceptable to the Administrative Agent and the Issuing Bank, of the Commitments
and all Letters of Credit issued hereunder and the termination of this
Agreement, the Swap Agreement Obligations and the Banking Services Obligations.
SECTION 10.12. Liability Cumulative. The liability of each Loan Party as a Loan
Guarantor under this Article X is in addition to and shall be cumulative with
all liabilities of each Loan Party to the Administrative Agent, the Issuing Bank
and the Lenders under this Agreement and the other Loan Documents to which such
Loan Party is a party or in respect of any obligations or liabilities of the
other Loan Parties, without any limitation as to amount, unless the instrument
or agreement evidencing or creating such other liability specifically provides
to the contrary.

SECTION 10.13. Keepwell. Each Qualified ECP Guarantor hereby jointly and
severally absolutely, unconditionally and irrevocably undertakes to provide such
funds or other support as may be needed from time to time by each other Loan
Party to honor all of its obligations under this Guarantee in respect of a Swap
Obligation (provided, however, that each Qualified ECP Guarantor shall only be
liable under this Section 10.13 for the maximum amount of such liability that
can be hereby incurred without rendering its obligations under this Section
10.13 or otherwise under this Loan Guaranty voidable under applicable law
relating to fraudulent conveyance or fraudulent transfer, and not for any
greater amount). Except as otherwise provided herein, the obligations of each
Qualified ECP Guarantor under this Section 10.13 shall remain in full force and
effect until the termination of all Swap Obligations. Each Qualified ECP
Guarantor intends that this Section 10.13 constitute, and this Section 10.13
shall be deemed to constitute, a “keepwell, support, or other agreement” for the
benefit of each other Loan Party for all purposes of Section 1a(18)(A)(v)(II) of
the Commodity Exchange Act.

action thereunder except any action specifically provided by the Loan Documents
to be taken by the Borrower Representative.

of its duties as the Borrower Representative hereunder and under any other Loan

Representative hereunder shall constitute notice to each Borrower on the date
received by the Borrower Representative.

of the Administrative Agent, the Borrower Representative may resign at any time,
such resignation to be effective upon the appointment of a successor Borrower
Representative. The Administrative Agent shall give prompt written notice of
such resignation to the Lenders.

or instruments as shall be necessary or appropriate to effect the purposes of
the Loan Documents, including, without limitation, the Borrowing Base
Certificates and the Compliance Certificates. Each Borrower agrees that any
action taken by the Borrower Representative or the Borrowers in accordance with
the terms of this Agreement or the other Loan Documents, and the exercise by the
Borrower Representative of its powers set forth therein or herein, together with
such other powers that are reasonably incidental thereto, shall be binding upon
all of the Borrowers.

SECTION 11.07. Reporting. Each Borrower hereby agrees that such Borrower shall
furnish promptly after each fiscal month to the Borrower Representative a copy
