assigns, conveys, mortgages, pledges, hypothecates, transfers, confirms and grants unto the Secured
Party, for the equal and ratable benefit and security of the Noteholders, a lien on and a first

action to collect or enforce any performance or the payment of any amounts which may have been

     3. Further Assurances.

          Concurrently with the execution and delivery of this Agreement, and thereafter at any time and
from time to time upon reasonable request of the Required Holders, each Pledgor shall execute and
deliver to the Secured Party all such financing statements, continuation financing statements,
assignments, certificates and documents of title, affidavits, reports, notices, schedules of
account, letters of authority, further pledges, powers of attorney and all other documents
(collectively, “Pledge Documents”) which the Required Holders may reasonably request, and in form
reasonably satisfactory to the Required Holders, and take such other action as the Required Holders
may reasonably request, to create and maintain, perfect and continue perfected, a Prior Security
Interest in favor of the Secured Party in the Pledged Collateral and to fully consummate the
transactions contemplated by this Agreement. Each Pledgor hereby irrevocably makes, constitutes and
appoints the Secured Party (and any of the Secured Party’s officers or employees or agents
designated by the Secured Party) as such Pledgor’s true and

5

 

lawful attorney with power to sign the name of such Pledgor on all or any of the Pledge
Documents which the Secured Party determines must be executed, filed, recorded or sent in order to
perfect or continue perfected the Secured Party’s security interest in the Pledged Collateral in
any jurisdiction. Such power, being coupled with an interest, is irrevocable until all of the
Secured Obligations have been indefeasibly paid and performed in full.

     4. Pledged Companies Acknowledgment and Assignment of Pledged Collateral.

          Each Pledgor shall cause each Pledged Company the Equity Interests in which are pledged or
required to be pledged by such Pledgor hereunder, to execute and deliver to the Secured Party,
concurrently with such pledge, an Acknowledgment Regarding Pledge Agreement (“Acknowledgment”) in
the form attached as Exhibit A hereto. Concurrently with its execution and delivery hereof or of a
Joinder Agreement, (i) each Pledgor of any membership interests in any Pledged Company shall
execute and deliver to the Secured Party, with respect to all relevant Pledged Collateral, a fully
executed Assignment of Membership Interest in the form attached as Exhibit B hereto; and (ii) each
Pledgor of any capital stock in any Pledged Company shall execute and deliver to the Secured Party
a fully executed Stock Power in the form attached as Exhibit C hereto. Each Pledgor hereby
authorizes the Secured Party, after the occurrence and during the continuance of an Event of
Default, and upon the completion of a sale conducted pursuant to Article 9 of the Code, to complete
the Assignment of Membership Interest or Stock Power, as applicable, and if the assignee is not the
Secured Party, to fill in the name of the purchaser of the Pledged Collateral at such sale
conducted pursuant to Article 9 of the Code as the assignee, and the date on which such sale was
conducted, and, thereafter, to deliver a true copy of the fully executed original of such
Assignment of Membership Interest or Stock Power, as the case may be, to the Pledged Company, and,
if any, other members or shareholders of the Pledged Company. Each Pledgor agrees that any Pledged
Company and its constituent members or shareholders shall be entitled to rely conclusively on such
Assignment of Membership Interest or Stock Power and shall have no liability to such Pledgor for
any loss of damage which such Pledgor may incur by reason of such reliance, this sentence being
expressly for the benefit of each such Pledged Company and such members or shareholders.

     5. Representations and Warranties.

          The Pledgors hereby jointly and severally represent and warrant to the Secured Party as
follows:

          (a) Each Pledgor has and will continue to have (or, in the case of after-acquired Pledged

(vii) and (viii) of the definition of that term).

          (b) All Equity Interests in any Pledged Company included in the Pledged Collateral have been
duly authorized and validly issued to a Pledgor (as set forth on Schedule 1 hereto as the same may
be updated, restated or otherwise modified from time to time in accordance with the terms hereof),
are fully paid and nonassessable and constitute one hundred

6

 

percent (100 %) of the issued and outstanding Equity Interests (exclusive of any non-economic
interest held by any Independent Manager) of such Pledged Company.

          (c) The security interests in the Pledged Collateral granted hereunder are valid, perfected
and of first priority, subject to no Lien in favor of any other Person except for the junior lien
securing the obligations under the Bank Financing Documents and additional Permitted Liens (other
than Permitted Liens of the types described in clauses (iv), (vii) and (viii) of the definition of
that term).

          (d) There are no restrictions upon the transfer of the Pledged Collateral, other than
restrictions thereon set forth in the Financing Documents and the Bank Financing Documents, and
each Pledgor has the power, authority and right to transfer the Pledged Collateral owned by such
Pledgor free of any encumbrances and without obtaining the consent of any other Person.

          (e) Each Pledgor has all necessary corporate or limited liability company power to execute and
deliver and perform its obligations under this Agreement.

          (f) There are no actions, suits, proceedings or investigations pending or, to the knowledge of

is in violation of any order, writ, injunction or decree of any Official Body which, either
individually or in the aggregate, could reasonably be expected to have a material adverse effect on

binding obligation of each Pledgor, enforceable against such Pledgor in accordance with its terms,
except to the extent that such enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting the enforceability of creditor’s rights
generally or by general equitable principles limiting the availability of the right of specific
performance or other equitable remedies.

          (h) Neither the execution and delivery by any Pledgor of this Agreement, or of a Joinder
Agreement pursuant to which it shall have become a party hereto as a Pledgor hereunder, nor
compliance by said Pledgor with the terms and provisions hereof, nor the enforcement of any rights
hereunder (including, but not limited to, a foreclosure sale of the Pledged Collateral), will (i)
violate any provision of any Law, or (ii) conflict with or result in a breach of any of the terms,
conditions or provisions of any judgment, order, injunction, decree or ruling of any Official Body

which such Pledgor is a party or by which such Pledgor is bound, or (iii) any Coal Lease or any of
the Coal Supply Contracts or any permit; provided that, the Pledgors make no representation as to

similar agreements are applicable to any of the Pledged Collateral; the applicable Organizational

same organizational type organized under the laws of the jurisdiction of organization of such
Pledged Company; and, all rights of each Pledgor in connection with its ownership of each of the
Pledged Companies which is a corporation are evidenced and governed solely by the stock
certificates, instruments or other documents evidencing ownership, the applicable Organizational
Documents of such Pledged Company, and applicable law.

          (k) There is no action or legal, administrative or other proceeding pending or, to any
Pledgor’s knowledge, threatened which materially and adversely affects any Pledgor’s title to any
Pledged Collateral or its grant of a security interest hereunder in any Pledged Collateral, nor
does any Pledgor know of any basis for the assertion of any such claim.

          (l) True and complete copies of the Organizational Documents of each Pledged Company are

          (a) Each Pledgor shall do all reasonable acts that may be necessary and appropriate to
maintain, preserve and protect the Pledged Collateral; each Pledgor shall be responsible for the
risk of loss of, damage to, or destruction of the Pledged Collateral owned by such Pledgor, unless

Pledgor shall notify the Secured Party in writing at least ten (10) Business Days prior to any
change in such Pledgor’s chief executive office address.

          (b) Each Pledgor shall appear in and defend any action or proceeding of which such Pledgor is

however, that with the consent of the Secured Party, which shall not be unreasonably withheld or
delayed, such Pledgor may settle any such actions or proceedings with respect to the Pledged
Collateral.

          (c) Each Pledgor shall, and shall cause each of the Pledged Companies the Equity Interests in

nature imposed by any Official Body on any of the Pledged Collateral, except to the extent the same
are being contested in good faith and by appropriate and lawful proceedings diligently conducted

shall have been made, but only to the extent that failure to discharge any thereof would not result
in any additional liability which would adversely affect to a material extent the financial
condition of any Pledgor or Subsidiary of any Pledgor or which would affect a material portion of
the Pledged Collateral, provided, that such Pledgor and its Subsidiaries will pay all such
liabilities forthwith upon the commencement of proceedings to foreclose any Lien which may have
attached as security therefor.

          (f) Each Pledgor shall permit the Secured Party, its officers, employees and agents, at

Financing Documents in favor of the Bank Lenders, and additional Permitted Liens (other than
Permitted Liens of the types described in clauses (iv), (vii) and (viii) of the definition of that
term set forth in Schedule B to the Note Agreement); or (iii) with respect to a Pledgor of
membership interests in the Company, take any action in furtherance of any modification of the
Organizational Documents of the Company, or any other action, that would have the effect of
constituting member interests in the Company “securities” within the meaning, or otherwise
subjecting such member interests to the coverage, of Article 8 of the Uniform Commercial Code of
any jurisdiction.

          (j) Each Pledgor shall, at its own expense, perform and observe all of the terms and
provisions of the applicable Organizational Documents to be performed or observed by such Pledgor,

have the right to deal with such Pledged Collateral and to receive distributions made in respect of
any Equity Interests included in such Pledged Collateral and in the ordinary course of business,
for application to any purpose and in any manner not inconsistent with the terms of this Agreement
(including, without limitation, Section 6(k)), the Note Agreement or any of the other Financing
Documents; provided, however, that such Pledgor shall not exercise or shall refrain from exercising
any such right if it would result in a Potential Default or an Event of Default or have a material
adverse effect on the value of any Pledged Collateral. Without limiting the foregoing and in
addition thereto, no Pledgor shall vote to enable, or take any other action to permit, any Pledged
Company to issue any Equity Interests or enter into or become

10

 

obligated pursuant to any agreement or undertaking restricting the right or ability of any
Pledgor or the Secured Party to sell, assign or transfer any of the Pledged Collateral.

          (b) Upon the occurrence and during the continuance of an Event of Default, the Secured Party,
at the expense of the Pledgors, may: (i) take control of and manage all or any of the Pledged
Collateral; (ii) apply to the payment of any of the Secured Obligations, whether any be due and
payable or not, any moneys, including cash dividends and income from any Pledged Collateral, now or
hereafter in the hands of the Secured Party, on deposit or otherwise, belonging to the Pledgors, as
the Secured Party shall determine; and (iii) do anything which any Pledgor is required but fails to
do hereunder.

          (c) If any Pledgor fails to perform any agreement contained herein, the Secured Party may (but
shall have no obligation to) perform or cause the performance of such agreement, and the expenses
of the Secured Party incurred in connection therewith shall be payable by such Pledgor.

          (d) Each Pledgor hereby appoints the Secured Party to be such Pledgor’s attorney-in-fact with
full authority in the place and stead of such Pledgor and in the name of such Pledgor or otherwise,
from time to time (but only upon the occurrence and during the continuance of an Event of Default)
in the Secured Party’s discretion to take any action and to execute any instrument which the
Secured Party may deem necessary or advisable to accomplish the purposes of this Agreement,
including, without limitation, to receive, endorse and collect all instruments made payable to such
Pledgor representing any dividend or other distribution in respect of any Pledged Collateral or any
part thereof and to give full discharge for the same.

     8. Additional Remedies Upon Event of Default.

          Upon the occurrence of any Event of Default and for so long as such Event of Default shall be
continuing, the Secured Party shall have, in addition to all rights and remedies of a secured party
under the Code or other applicable Law, and in addition to its rights under Section 7 and under the
other Financing Documents, the following rights and remedies:

          (a) The Secured Party may, after ten (10) Business Days’ advance
written notice to a Pledgor, sell, assign, give an option or options to
purchase or otherwise dispose of such Pledgor’s Pledged Collateral or any part
thereof at public or private sale, at any of the Secured Party’s offices or
elsewhere, for cash, on credit or for future delivery, and upon such other
terms as the Secured Party may deem commercially reasonable. Each Pledgor
agrees that ten (10) Business Days’ advance notice of the time and place of any
public sale or the time after which any private sale is to be made shall
constitute reasonable notification. The Secured Party shall not be obligated to
make any sale of Pledged Collateral regardless of notice of sale having been
given. The Secured Party may adjourn any public or private sale from time to
time by announcement at the time and place
fixed therefor, and such sale may, without further notice, be
made at the time and place to which it was so adjourned. Each
Pledgor recognizes that the Secured Party may be compelled to
resort to one or more private sales of the Pledged Collateral
to a restricted group of purchasers who will be obliged to
agree, among other things, to acquire Equity Interests,
securities, or other ownership interests included in such
Pledged Collateral for their own account for investment and
not with a view to the distribution or resale thereof.

11

 

          (b) The proceeds of any collection, sale or other disposition of the Pledged Collateral, or
any part thereof, shall, after the Secured Party has made all deductions of reasonable expenses,
including but not limited to reasonable attorneys’ fees and other expenses incurred in connection
with repossession, collection, sale or disposition of such Pledged Collateral or in connection with
the enforcement of the Secured Party’s rights with respect to the Pledged Collateral, including in
any insolvency, bankruptcy or reorganization proceedings, be applied as provided in Section 5.4 of
the Collateral Agency Agreement.

          (c) (i) The Secured Party shall have the right to have the Pledged Collateral, or from time to
time any part thereof, transferred into the name of the Secured Party pursuant to Section 3.

               (ii) All rights of each Pledgor to exercise the voting and other consensual rights which such
Pledgor would otherwise be entitled to exercise pursuant to Section 7(a) and to receive
distributions in respect of Pledged Collateral shall cease, and all such rights shall thereupon
become vested in the Secured Party, who shall thereafter upon notice to such Pledgor have the sole
right to exercise such voting and other consensual rights and to receive 100% of all such
distributions, which shall be promptly applied by Secured Party as provided in Section 5.4 of the
Collateral Agency Agreement.

               (iii) All distributions which are received by any Pledgor contrary to the provisions of
Section 8(b) or Section 8(c)(ii) shall be received in trust for the benefit of the Secured Party,
shall be segregated from other funds of such Pledgor, and forthwith shall be paid over by such
Pledgor to the Secured Party as Pledged Collateral in the same form as received (with any necessary
endorsements), unless all Events of Default shall have been previously cured by the Pledgors or
waived in writing by the Noteholders in the manner provided in the Note Agreement.

               (iv) The Secured Party shall have the right to take control of and manage all or any of the
Pledged Collateral.

     9. Secured Party’s Duties.

          The powers conferred on the Secured Party hereunder are solely to protect its interest in the
Pledged Collateral and shall not impose any duty upon it to exercise any such
powers. Except for the safe custody of any Pledged Collateral in its possession and the
accounting for moneys actually received by it hereunder, the Secured Party shall have no duty as to
any Pledged Collateral or as to the taking of any steps to preserve rights against prior parties or
any other rights pertaining to any Pledged Collateral.

     10. No Waiver; Cumulative Remedies.

          No failure to exercise, and no delay in exercising, on the part of the Secured Party, any
right, power or privilege available it hereunder or under applicable law shall operate as a waiver
thereof; nor shall any single or partial exercise of any such right, power or privilege preclude
any further exercise thereof or the exercise of any other right, power or privilege. The remedies
herein provided are cumulative and not exclusive of any remedies provided under the other Financing
Documents or by Law. Each Pledgor waives any right to require the Secured

12

 

Party to proceed against
any other Person or to exhaust any of the Pledged Collateral or other security for the Secured
Obligations or to pursue any remedy in the Secured Party’s power.

     11. Assignment.

          Subject to the provisions of the Collateral Agency Agreement, all rights of the Secured Party
under this Agreement shall inure to the benefit of its successors and assigns (including any
successor Collateral Agent under the Collateral Agency Agreement). All obligations of each Pledgor
hereunder shall bind its successors and assigns; provided, however, no Pledgor may assign or
transfer any of its rights and obligations hereunder or any interest herein.

     12. Additional Pledgors; Additional Pledged Collateral.

     In the event that, at any time subsequent to the date hereof, any Person (other than TWCC)
shall become a Subsidiary of the Company or of a Guarantor (including any Subsidiary of the Company
which, pursuant to Section 9.2 of the Note Agreement, shall have become a Guarantor subsequent to
the date hereof), then, in each such event (hereinafter referred to as an “Acquisition Event”),
such Person, forthwith upon the occurrence of such Acquisition Event and without further act by any
party, shall be deemed and become a Pledged Company for all purposes of this Agreement, and as
promptly as practical (and in any event not later than sixty (60) days) following such Acquisition
Event:

     (i) If such Person shall have become a Subsidiary of a Guarantor and the following
clause (ii) hereof shall not be applicable, the Company shall cause such Guarantor to (A)
join in this Agreement as an Additional Pledgor hereunder and become bound by the terms
hereof by executing and delivering to the Collateral Agent a Joinder Agreement substantially
in the form of Exhibit G(1) to the Note Agreement (a “Joinder Agreement”), completed in a
manner satisfactory to the Collateral Agent, which, without limiting the provisions of said
Section 9.2 of the Note Agreement, shall be effective to confirm the pledge to the Secured
Party hereunder of all right, title and interest of such Guarantor in to and under all
Pledged Collateral relating to such Person and (B) deliver to the Secured Party all such
documents and instruments with respect to such Pledged Collateral as shall be required by
Section 2(b) hereof.

     (ii) If such Person shall have become a Subsidiary of the Company or of any Guarantor
which shall have theretofore become an Additional Pledgor hereunder, the Company or such
Additional Pledgor, as the case may be, shall comply with Section 6(g) hereof with respect
to the Pledged Collateral relating to such Person.

     (iii) The Pledgors shall furnish to the Secured Party a revised Schedule 1 hereto,
identifying such Person and the Equity Interests in such Person, reflecting the pledge to
the Secured Party hereunder of all Pledged Collateral relating to such Person, and showing
all Equity Interests owned by such Person in any other Person.

13

 

          Nothing in this Section 12 is intended or shall be construed to permit the Company or any
other Obligor to consummate any Acquisition Event or any other transaction that it would not be
permitted to consummate pursuant to the terms of the Note Agreement.

     13. Recourse to Parent.

     The Secured Party’s and the Noteholders’ recourse against Parent hereunder shall be solely
limited to Parent’s interest in the Pledged Collateral and the enforcement of their respective
rights under this Agreement.

     14. Severability.

          Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall,
as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability
without invalidating the remaining provisions hereof, and any such prohibition or unenforceability
in any jurisdiction shall (to the full extent permitted by law) not invalidate or render
unenforceable such provision in any other jurisdiction.

     15. Governing Law.

          This Agreement shall be governed by, and construed and enforced in accordance with, the laws
of the State of New York.

     16. Notices.

          All notices and other communications hereunder shall be in writing and shall be delivered by
(i) first-class certified mail, postage prepaid, return receipt requested, (ii) express delivery
such as Federal Express or similar service, or (iii) personal delivery, addressed (A) if to a
Pledgor, to the address of such Pledgor set forth on the appropriate signature page hereof or in
the Joinder Agreement to which it is a party, or at such other address as such Pledgor shall have
furnished to the Secured Party and the Noteholders in writing, with a copy to Wilmer Cutler
Pickering Hale and Dorr LLP, 60 State Street, Boston Massachusetts 02109, Attn: Michael Levitin,
Esq., or such other address as the Company or such Pledgor shall have furnished to the Secured
Party and the Noteholders in writing, or (B) if to the Secured Party, to it at One U.S. Bank Plaza,
Mail Code: SL-TW-06CT, St. Louis, MO 63101, Attention: Brian Kabbes, or at such other address as
the Secured Party shall have furnished to the Pledgors and the Noteholders in writing, or (C) if to
a Noteholder, at the address of such Noteholder specified, or provided for
in accordance with, Section 18 of the Note Agreement or at such other address as such
Noteholder shall have furnished to the Pledgors and the Secured Party in writing. Any notice shall
be deemed to be given only when actually received.

     17. Specific Performance.

          Each Pledgor acknowledges and agrees that, in addition to the other rights of the Secured
Party hereunder and under the other Financing Documents, because the Secured Party’s remedies at
law for failure of such Pledgor to comply with the provisions hereof relating to the Secured
Party’s rights (i) to inspect the books and records related to the Pledged Collateral, (ii) to
receive the various notifications such Pledgor is required to deliver hereunder, (iii) to obtain

14

 

copies of agreements and documents as provided herein with respect to the Pledged Collateral, (iv)
to enforce the provisions hereof pursuant to which such Pledgor has appointed the Secured Party its
attorney-in-fact, and (v) to enforce the Secured Party’s remedies hereunder, would be inadequate
and that any such failure would not be adequately compensable in money damages, such Pledgor agrees
that each such provision hereof may be specifically enforced.

     18. Consent to Jurisdiction.

          EACH OF THE PLEDGORS AGREES THAT ANY LEGAL ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO
THIS AGREEMENT OR ANY OTHER DOCUMENT EXECUTED IN CONNECTION HEREWITH, OR ANY LEGAL ACTION OR
PROCEEDING TO EXECUTE OR OTHERWISE ENFORCE ANY JUDGMENT OBTAINED AGAINST THE PLEDGORS, OR ANY OF
THEM, FOR BREACH HEREOF, OR AGAINST ANY OF THEIR PROPERTIES, MAY BE BROUGHT IN THE COURTS OF THE
STATE OF NEW YORK OR THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK BY ANY
NOTEHOLDER OR THE SECURED PARTY OR ON BEHALF OF ANY NOTEHOLDER OR THE SECURED PARTY, AS SUCH
NOTEHOLDER OR THE SECURED PARTY MAY ELECT, AND EACH PLEDGOR HEREBY IRREVOCABLY AND UNCONDITIONALLY
SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF SUCH COURTS FOR PURPOSES OF ANY SUCH LEGAL ACTION OR
PROCEEDING. EACH PLEDGOR HEREBY AGREES THAT SERVICE OF PROCESS IN ANY SUCH PROCEEDING MAY BE
EFFECTED BY MAILING A COPY THEREOF BY REGISTERED OR CERTIFIED MAIL (OR ANY SUBSTANTIALLY SIMILAR
FORM OF MAIL), POSTAGE PREPAID, TO IT AT ITS ADDRESS SPECIFIED IN SECTION 16 HEREOF OR AT SUCH
OTHER ADDRESS OF WHICH THE SECURED PARTY AND EACH NOTEHOLDER SHALL HAVE BEEN NOTIFIED PURSUANT
HERETO. IN ADDITION, EACH PLEDGOR HEREBY IRREVOCABLY WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW,
ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT BROUGHT IN THE COURTS OF THE STATE OF NEW
YORK OR THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK, AND ANY CLAIM THAT
ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT
FORUM.

     19. 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 OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT
OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF
ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE
EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE

15

 

OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE
MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     20. Entire Agreement; Amendments.

          This Agreement together with the other Financing Documents constitutes the entire agreement
between and among the parties with respect to the subject matter hereof and supersedes all prior
agreements relating to a grant of a security interest in the Pledged Collateral by any Pledgor.
This Agreement may not be amended or supplemented, other than pursuant to a Joinder Agreement
entered into as contemplated by Section 12, except by a writing signed by the Secured Party and the
Pledgors.

     21. Counterparts.

          This Agreement may be executed in any number of counterparts, and by different parties hereto
in separate counterparts, each of which when so executed shall be deemed an original and all of
which taken together shall constitute but one and the same agreement.

     22. Descriptive Headings; Etc.

          The descriptive section and other subdivision headings which are used in this Agreement are
for the convenience of the parties only and shall not affect the meaning of any provision of this
Agreement. References in this Agreement to a particular section or other subdivision, or to a
particular schedule or exhibit, shall, unless otherwise specified herein, be deemed a reference to

to perform its obligations hereunder shall not affect the Obligations of the Borrower to any other
party nor shall any other party be liable for the failure of such Bank to perform its obligations
hereunder. The Banks shall have no obligation to make Revolving Credit Loans hereunder on or after
the Expiration Date.

     2.3 Commitment Fees.

          Accruing from the date hereof until the Expiration Date, the Borrower agrees to pay to the
Agent for the account of each Bank, as consideration for such Bank’s Revolving Credit Commitment
hereunder, a nonrefundable commitment fee (the “Commitment Fee”) equal to 0.50% per annum (computed
on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed) on the
average daily difference between the amount of (i) such Bank’s Revolving Credit Commitment as the
same may be constituted from time to time and the (ii) the sum of such Bank’s Revolving Credit
Loans outstanding (for purposes of this computation, PNC Bank’s Swing Loans shall be deemed to be
borrowed amounts under its Revolving Credit Commitment) plus its Ratable Share of Letters of Credit
Outstanding. All Commitment Fees shall be payable in arrears on the last Business Day of each
June, September, December and March after the date hereof and on the Expiration Date or upon
acceleration of the Notes.

     2.4 Intentionally Omitted.

2.5 Revolving Credit Loan Requests; Swing Loan Requests.

          2.5.1 Revolving Credit Loan Requests.

          Except as otherwise provided herein, the Borrower may from time to time prior to the
Expiration Date request the Banks to make Revolving Credit Loans, or renew or convert the Interest
Rate Option applicable to existing Revolving Credit Loans pursuant to Section 4.2 [Interest
Periods], by delivering to the Agent, not later than 12:00 noon, Pittsburgh time, (i) three (3)
Business Days prior to the proposed Borrowing Date with respect to the making of Revolving Credit
Loans to which the Libor-Rate Option applies or the conversion to or the renewal of the Libor-Rate

Revolving Credit Loan to which the Base Rate Option applies or the last day of the preceding
Interest Period with respect to the conversion to the Base Rate Option for any Loan, of a duly
completed request therefor substantially in the form of Exhibit 2.5.1 or a request by
telephone immediately confirmed in writing by letter, facsimile or telex in such form (each, a

32

 

“Loan Request”), it being understood that the Agent may rely on the authority of any
individual making such a telephonic request without the necessity of receipt of such written
confirmation. Each Loan Request shall be irrevocable and shall specify (i) the proposed Borrowing
Date; (ii) the aggregate amount of the proposed Loans comprising each Borrowing Tranche, which
shall be in integral multiples of $500,000 and not less than $1,000,000 for each Borrowing Tranche
to which the Libor-Rate Option applies and in integral multiples of $100,000 and not less than the
lesser of $500,000 or the maximum amount available for Borrowing Tranches to which the Base Rate
Option applies; (iii) whether the Libor-Rate Option or Base Rate Option shall apply to the proposed
Loans comprising the applicable Borrowing Tranche; and (iv) in the case of a Borrowing Tranche to
which the Libor-Rate Option applies, an appropriate Interest Period for the Loans comprising such
Borrowing Tranche.

          2.5.2 Swing Loan Requests.

               Except as otherwise provided herein, the Borrower may from time to time prior to the
Expiration Date request PNC Bank to make Swing Loans by delivery to PNC Bank not later than 1:00
p.m. Pittsburgh time on the proposed Borrowing Date of a duly completed request therefor
substantially in the form of Exhibit 2.5.2 hereto or a request by telephone immediately
confirmed in writing by letter, facsimile or telex (each, a “Swing Loan Request”), it being
understood that the Agent may rely on the authority of any individual making such a telephonic
request without the necessity of receipt of such written confirmation. Each Swing Loan Request
shall be irrevocable and shall specify the proposed Borrowing Date and the principal amount of such
Swing Loan, which shall be in integral multiples of $100,000 and not less than $100,000.

     2.6 Making Revolving Credit Loans and Swing Loans; Swing Notes; Presumptions by the
Agent.

          2.6.1 Making Revolving Credit Loans.

          The Agent shall, promptly after receipt by it of a Loan Request pursuant to Section 2.5
[Revolving Credit Loan Requests], notify the Banks of its receipt of such Loan Request specifying:
(i) the proposed Borrowing Date and the time and method of disbursement of the Revolving Credit
Loans requested thereby; (ii) the amount and type of each such Revolving Credit Loan and the
applicable Interest Period (if any); and (iii) the apportionment among the Banks of such Revolving
Credit Loans as determined by the Agent in accordance with Section 2.2 [Nature of Banks’
Obligations]. Each Bank shall remit the principal amount of each Revolving Credit Loan to the
Agent such that the Agent is able to, and the Agent shall, to the extent the Banks have made funds
available to it for such purpose and subject to Section 7.2 [Each Additional Loan], fund such
Revolving Credit Loans to the Borrower in U.S. Dollars and immediately available funds at the
Principal Office prior to 2:00 p.m., Pittsburgh time, on the applicable Borrowing Date, provided
that if any Bank fails to remit such funds to the Agent in a timely manner, the Agent may elect in
its sole discretion to fund with its own funds the Revolving Credit Loans of such Bank on such
Borrowing Date, and such Bank shall be subject to the repayment obligation in Section 10.15
[Availability of Funds].

          2.6.2 Making Swing Loans.

33

 

               So long as PNC Bank elects to make Swing Loans, PNC Bank shall, after receipt by it of a Swing
Loan Request pursuant to Section 2.5.2 [Swing Loan Request], fund such Swing Loan to the Borrower
in U.S. Dollars and immediately available funds at the Principal Office prior to 4:00 p.m.
Pittsburgh time on the Borrowing Date.

          2.6.3 Presumptions by the Agent.

               Unless the Agent shall have received notice from a Bank prior to the proposed date of any Loan
that such Bank will not make available to the Agent such Bank’s share of such Loan, the Agent may
assume that such Bank has made such share available on such date in accordance with Section 2.6.1
[Making Revolving Credit Loans] and may, in reliance upon such assumption, make available to the
Borrower a corresponding amount. In such event, if a Bank has not in fact made its share of the
applicable Loan available to the Agent, then the applicable Bank and the Borrower severally agree
to pay to the Agent forthwith on demand such corresponding amount with interest thereon, for each
day from and including the date such amount is made available to the Borrower to but excluding the
date of payment to the Agent, at (i) in the case of a payment to be made by such Bank, the greater
of the Federal Funds Effective Rate and a rate determined by the Agent in accordance with banking
industry rules on interbank compensation and (ii) in the case of a payment to be made by the
Borrower, the interest rate applicable to Loans under the Base Rate Option or LIBOR Rate Option, as
applicable. If such Bank pays its share of the applicable Loan to the Agent, then the amount so
paid shall constitute such Bank’s Loan. Any payment by the Borrower shall be without prejudice to
any claim the Borrower may have against a Bank that shall have failed to make such payment to the
Agent.

     2.7 Revolving Credit Notes; Swing Line Notes.

          The Obligation of the Borrower to repay the aggregate unpaid principal amount of the Revolving
Credit Loans made to it by each Bank, together with interest thereon, shall be evidenced by a
Revolving Credit Note dated the Closing Date payable to the order of such Bank in a face amount
equal to the Revolving Credit Commitment of such Bank. The obligation of the Borrower to repay the
unpaid principal amount of the Swing Loans made to it by PNC Bank together with interest thereon
shall be evidenced by a demand promissory note of the Borrower dated the Closing Date in
substantially the form attached hereto as Exhibit 1.1(S)(2) payable to the order of PNC
Bank in a face amount equal to the Swing Loan Commitment.

     2.8 Use of Proceeds.

          The proceeds of the Revolving Credit Loans shall be used for (i) the refinancing of existing
indebtedness, (ii) provide a one-time distribution to Westmoreland Coal Company and (iii) working
capital and general corporate purposes and in accordance with Section 8.1.11 [Use of Proceeds].

     2.9 Letter of Credit Subfacility.

          2.9.1 Issuance of Letters of Credit.

               On the Closing Date, the outstanding Letters of Credit previously issued by PNC Bank as an
“Issuing Bank” under the Existing Credit Agreement that are set forth on Schedule 2.9.1
(the “Existing Letters of Credit”) will automatically, without any action on the

34

 

part of any Person, be deemed to be Letters of Credit issued hereunder for the account of the
Borrower for all purposes of this Agreement and the other Loan Documents. In addition, Borrower
may request the issuance of a letter of credit (each a “Letter of Credit”) on behalf of itself or
another Loan Party by delivering to the Agent a completed application and agreement for letters of
credit in such form as the Agent may specify from time to time by no later than 10:00 a.m.,
Pittsburgh time, at least five (5) Business Days, or such shorter period as may be agreed to by the
Agent, in advance of the proposed date of issuance. Each Letter of Credit shall be a Standby
Letter of Credit. Promptly after receipt of any letter of credit application, the Issuing Bank
shall confirm with the Agent (by telephone or in writing) that the Agent has received a copy of
such Letter of Credit application and if not, such Issuing Bank will provide Agent with a copy
thereof. Unless the Issuing Bank has received notice from any Bank, Agent or any Loan Party, at
least one day prior to the requested date of issuance, amendment or extension of the applicable
Letter of Credit, that one or more applicable conditions in Section 7 [Conditions of Lending and
Issuance of Letter of Credit] is not satisfied, then, so long as there is no Event of Default or
Potential Default, subject to compliance with all of the terms and conditions set forth in this
Agreement, any Letter of Credit may be automatically renewable if such selection is made on the
application for such Letter of Credit. Subject to the terms and conditions hereof and in reliance
on the agreements of the other Banks set forth in this Section 2.9, the Agent will issue a Letter
of Credit or renew an existing Letter of Credit, provided that each Letter of Credit shall (A) have
a maximum maturity of twelve (12) months from the date of issuance, and (B) in no event expire
later than one (1) year beyond the expiration date, provided that any Letter of Credit scheduled to
expire after the Expiration Date is subject to the requirements in Section 2.9.10 [Cash Collateral
Prior to the Expiration Date]. In no event shall (i) the Letters of Credit Outstanding exceed, at
any one time, $15,000,000 or (ii) the Revolving Facility Usage exceed, at any one time, the
Revolving Credit Commitments or the Borrowing Base. Each request by the Borrower for the issuance,
amendment or extension of a Letter of Credit shall be deemed to be a representation by the Borrower
that it shall be in compliance with the preceding sentence and with Section 7.2 [Each Additional
Loan] after giving effect to the requested issuance, amendment or extension of such Letter of
Credit. Promptly after its delivery of any Letter of Credit or any amendment to a Letter of Credit
to the beneficiary thereof, the applicable Issuing Bank will also deliver to Borrower and Agent a
true and complete copy of such Letter of Credit or amendment.

          2.9.2 Letter of Credit Fees.

               The Borrower shall pay (i) to the Agent for the ratable account of the Banks a fee (the
“Letter of Credit Fee”) equal to the percentage per annum equal to the Revolving Credit Libor Rate
Option, and (ii) to the Agent for its own account a fronting fee equal to 0.25% per annum (computed
on the basis of a year of 360 days and actual days elapsed), which fees shall be computed on the
daily average Letters of Credit Outstanding and shall be payable quarterly in arrears commencing
with the last Business Day of each June, September, December and March following issuance of each
Letter of Credit and on the Expiration Date. The Borrower shall also pay to the Agent for the
Agent’s sole account the Agent’s then in effect customary fees and administrative expenses payable
with respect to the Letters of Credit as the Agent may generally charge or incur from time to time
in connection with the issuance, maintenance, modification (if any), assignment or transfer (if
any), negotiation, and administration of Letters of Credit.

35

 

          2.9.3 Disbursements, Reimbursement.

               2.9.3.1 Immediately upon the Issuance of each Letter of Credit, each Bank shall be deemed to,
and hereby irrevocably and unconditionally agrees to, purchase from the Agent a participation in
such Letter of Credit (including the Existing Letters of Credit) and each drawing thereunder in an
amount equal to such Bank’s Ratable Share of the maximum amount available to be drawn under such
Letter of Credit and the amount of such drawing, respectively.

               2.9.3.2 In the event of any request for a drawing under a Letter of Credit by the beneficiary
or transferee thereof, the Agent will promptly notify the Borrower. Provided that it shall have
received such notice, the Borrower shall reimburse (such obligation to reimburse the Agent shall
sometimes be referred to as a “Reimbursement Obligation”) the Agent prior to 12:00 noon, Pittsburgh
time on each date that an amount is paid by the Agent under any Letter of Credit (each such date,
an “Drawing Date”) in an amount equal to the amount so paid by the Agent. In the event the
Borrower fails to reimburse the Agent for the full amount of any drawing under any Letter of Credit
by 12:00 noon, Pittsburgh time, on the Drawing Date, the Agent will promptly notify each Bank
thereof, and the Borrower shall be deemed to have requested that Revolving Credit Loans be made by
the Banks under the Base Rate Option to be disbursed on the Drawing Date under such Letter of
Credit, subject to the amount of the unutilized portion of the Revolving Credit Commitment and
subject to the conditions set forth in Section 7.2 [Each Additional Loan] other than any notice
requirements. Any notice given by the Agent pursuant to this Section 2.9.3.2 may be oral if
immediately confirmed in writing; provided that the lack of such an immediate confirmation shall
not affect the conclusiveness or binding effect of such notice.

               2.9.3.3 Each Bank shall upon any notice pursuant to Section 2.9.3.2 make available to the
Agent an amount in immediately available funds equal to its Ratable Share of the amount of the
drawing, whereupon the participating Banks shall (subject to Section 2.9.3.4) each be deemed to
have made a Revolving Credit Loan under the Base Rate Option to the Borrower in that amount. If
any Bank so notified fails to make available to the Agent for the account of the Agent the amount
of such Bank’s Ratable Share of such amount by no later than 2:00 p.m., Pittsburgh time on the
Drawing Date, then interest shall accrue on such Bank’s obligation to make such payment, from the
Drawing Date to the date on which such Bank makes such payment (i) at a rate per annum equal to the
Federal Funds Effective Rate during the first three days following the Drawing Date and (ii) at a
rate per annum equal to the rate applicable to Loans under the Revolving Credit Base Rate Option on
and after the fourth day following the Drawing Date. The Agent will promptly give notice of the
occurrence of the Drawing Date, but failure of the Agent to give any such notice on the Drawing
Date or in sufficient time to enable any Bank to effect such payment on such date shall not relieve
such Bank from its obligation under this Section 2.9.3.3.

               2.9.3.4 With respect to any unreimbursed drawing that is not converted into Revolving Credit
Loans under the Base Rate Option to the Borrower in whole or in part as contemplated by
Section 2.9.3.2, because of the Borrower’s failure to satisfy the conditions set forth in
Section 7.2 [Each Additional Loan] other than any notice requirements or for any other reason, the
Borrower shall be deemed to have incurred from the Agent a borrowing (each a “Letter of Credit
Borrowing”) in the amount of such drawing. Such Letter of Credit Borrowing shall be due and
payable on demand (together with interest) and shall bear interest at the rate per annum applicable
to the Revolving Credit Loans under the Base Rate Option. Each Bank’s

36

 

payment to the Agent pursuant to Section 2.9.3.3 shall be deemed to be a payment in respect of
its participation in such Letter of Credit Borrowing and shall constitute a “Participation Advance”
from such Bank in satisfaction of its participation obligation under this Section 2.9.3.

          2.9.4 Repayment of Participation Advances.

               2.9.4.1 Upon (and only upon) receipt by the Agent for its account of immediately available
funds from the Borrower (i) in reimbursement of any payment made by the Agent under the Letter of
Credit with respect to which any Bank has made a Participation Advance to the Agent, or (ii) in
payment of interest on such a payment made by the Agent under such a Letter of Credit, the Agent
will pay to each Bank, in the same funds as those received by the Agent, the amount of such Bank’s
Ratable Share of such funds, except the Agent shall retain the amount of the Ratable Share of such
funds of any Bank that did not make a Participation Advance in respect of such payment by Agent.

               2.9.4.2 If the Agent is required at any time to return to any Loan Party, or to a trustee,
receiver, liquidator, custodian, or any official in any Insolvency Proceeding, any portion of the
payments made by any Loan Party to the Agent pursuant to Section 2.9.4.1 in reimbursement of a
payment made under the Letter of Credit or interest or fee thereon, each Bank shall, on demand of
the Agent, forthwith return to the Agent the amount of its Ratable Share of any amounts so returned
by the Agent plus interest thereon from the date such demand is made to the date such amounts are
returned by such Bank to the Agent, at a rate per annum equal to the Federal Funds Effective Rate
in effect from time to time.

          2.9.5 Documentation.

               Each Loan Party agrees to be bound by the terms of the Agent’s application and agreement for
letters of credit and the Agent’s written regulations and customary practices relating to letters
of credit, though such interpretation may be different from such Loan Party’s own. In the event of
a conflict between such application or agreement and this Agreement, this Agreement shall govern.
It is understood and agreed that, except in the case of gross negligence or willful misconduct, the
Agent shall not be liable for any error, negligence and/or mistakes, whether of omission or
commission, in following any Loan Party’s instructions or those contained in the Letters of Credit
or any modifications, amendments or supplements thereto.

          2.9.6 Determinations to Honor Drawing Requests.

               In determining whether to honor any request for drawing under any Letter of Credit by the
beneficiary thereof, the Agent shall be responsible only to determine that the documents and
certificates required to be delivered under such Letter of Credit have been delivered and that they
comply on their face with the requirements of such Letter of Credit.

          2.9.7 Nature of Participation and Reimbursement Obligations. 

               Each Bank’s obligation in accordance with this Agreement to make the Revolving Credit Loans or
Participation Advances, as contemplated by Section 2.9.3 [Disbursement, Reimbursement], as a result
of a drawing under a Letter of Credit, and the Obligations of the Borrower to reimburse the Agent
upon a draw under a Letter of Credit, shall

37

 

be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with
the terms of this Section 2.9 under all circumstances, including the following circumstances:

          (i) any set-off, counterclaim, recoupment, defense or other right which such Bank may have
against the Issuing Bank or any of its Affiliates, the Borrower or any other Person for any reason

Bank or any other Person for any reason whatsoever;

          (ii) the failure of any Loan Party or any other Person to comply, in connection with a Letter
of Credit Borrowing, with the conditions set forth in Section 2.1 [Revolving Credit Commitments],
2.5 [Revolving Credit Loan Requests], 2.6 [Making Revolving Credit Loans] or 7.2 [Each Additional
Loan] or as otherwise set forth in this Agreement for the making of a Revolving Credit Loan, it
being acknowledged that such conditions are not required for the making of a Letter of Credit
Borrowing and the obligation of the Banks to make Participation Advances under Section 2.9.3
[Disbursement, Reimbursement];

          (iii) any lack of validity or enforceability of any Letter of Credit;

          (iv) any claim of breach of warranty that might be made by any Loan Party or any Bank against
any beneficiary of a Letter of Credit, or the existence of any claim, set-off, recoupment,
counterclaim, crossclaim, defense or other right which any Loan Party or any Bank may have at any
time against a beneficiary, successor beneficiary any transferee or assignee of any Letter of
Credit or the proceeds thereof (or any Persons for whom any such transferee may be acting), the
Issuing Bank or its Affiliates or any Bank or any other Person, whether in connection with this
Agreement, the transactions contemplated herein or any unrelated transaction (including any
underlying transaction between any Loan Party or Subsidiaries of a Loan Party and the beneficiary
for which any Letter of Credit was procured);

          (v) the lack of power or authority of any signer of (or any defect in or forgery of any
signature or endorsement on) or the form of or lack of validity, sufficiency, accuracy,
enforceability or genuineness of any draft, demand, instrument, certificate or other document
presented under or in connection with any Letter of Credit, or any fraud or alleged fraud in
connection with any Letter of Credit, or the transport of any property or provision of services
relating to a Letter of Credit, in each case even if the Issuing Bank or any of its Affiliates has
been notified thereof;

          (vi) payment by the Agent under any Letter of Credit against presentation of a demand, draft
or certificate or other document which does not comply with the terms of such Letter of Credit;

          (vii) the solvency of, or any acts or omissions by, any beneficiary of any Letter of Credit,
or any other Person having a role in any transaction or obligation relating to a Letter of Credit,
or the existence, nature, quality, quantity, condition, value or other characteristic of any
property or services relating to a Letter of Credit;

          (viii) any failure by the Issuing Bank or any of its Affiliates to issue any Letter of Credit
in the form requested by any Loan Party, unless the Issuing Bank has received written notice from
such Loan Party of such failure within three Business Days after the Issuing Bank

38

 

shall have furnished such Loan Party and the Agent a copy of such Letter of Credit and such
error is material and no drawing has been made thereon prior to receipt of such notice;

          (ix) any adverse change in the business, operations, properties, assets, condition (financial
or otherwise) or prospects of any Loan Party or Subsidiaries of a Loan Party;

          (x) any breach of this Agreement or any other Loan Document by any party thereto;

          (xi) the occurrence or continuance of an Insolvency Proceeding with respect to any Loan Party;

          (xii) the fact that an Event of Default or a Potential Default shall have occurred and be

Commitments hereunder shall have been terminated; and

          (xiv) any other circumstance or happening whatsoever, whether or not similar to any of the
foregoing.

          2.9.8 Indemnity.

               In addition to amounts payable as provided in Section 10.5 [Reimbursement of Agent by
Borrower, Etc.], the Borrower hereby agrees to protect, indemnify, pay and save harmless the Agent
from and against any and all claims, demands, liabilities, damages, losses, costs, charges and
expenses (including reasonable fees, expenses and disbursements of counsel and allocated costs of
internal counsel) which the Agent may incur or be subject to as a consequence, direct or indirect,
of the issuance of any Letter of Credit, other than as a result of (A) the gross negligence or
willful misconduct of the Agent as determined by a final judgment of a court of competent
jurisdiction or (B) the wrongful dishonor by the Agent of a proper demand for payment made under
any Letter of Credit, except if such dishonor resulted from any act or omission, whether rightful
or wrongful, of any present or future de jure or de facto government or governmental authority (all
such acts or omissions herein called “Governmental Acts”).

          2.9.9 Liability for Acts and Omissions.

               As between any Loan Party and the Agent, such Loan Party assumes all risks of the acts and
omissions of, or misuse of the Letters of Credit by, the respective beneficiaries of such Letters
of Credit. In furtherance and not in limitation of the foregoing, the Agent shall not be
responsible for: (i) the form, validity, sufficiency, accuracy, genuineness or legal effect of any
document submitted by any party in connection with the application for an issuance of any such
Letter of Credit, even if it should in fact prove to be in any or all respects invalid,
insufficient, inaccurate, fraudulent or forged (even if the Agent shall have been notified
thereof); (ii) the validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign any such Letter of Credit or the rights or benefits thereunder or
proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason;
(iii) the failure of the beneficiary of any such Letter of Credit, or any other party to which such
Letter of

39

 

Credit may be transferred, to comply fully with any conditions required in order to draw upon
such Letter of Credit or any other claim of any Loan Party against any beneficiary of such Letter
of Credit, or any such transferee, or any dispute between or among any Loan Party and any
beneficiary of any Letter of Credit or any such transferee; (iv) errors, omissions, interruptions
or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex or
otherwise, whether or not they be in cipher; (v) errors in interpretation of technical terms;
(vi) any loss or delay in the transmission or otherwise of any document required in order to make a
drawing under any such Letter of Credit or of the proceeds thereof; (vii) the misapplication by the
beneficiary of any such Letter of Credit of the proceeds of any drawing under such Letter of
Credit; or (viii) any consequences arising from causes beyond the control of the Agent, including
any Governmental Acts, and none of the above shall affect or impair, or prevent the vesting of, any
of the Agent’s rights or powers hereunder. Nothing in the preceding sentence shall relieve the
Agent from liability for the Agent’s gross negligence or willful misconduct in connection with
actions or omissions described in such clauses(i) through (viii) of such sentence.

               Without limiting the generality of the foregoing, the Issuing Bank and each of its Affiliates
(i) may rely on any oral or other communication believed in good faith by the Issuing Bank or such
Affiliate to have been authorized or given by or on behalf of the applicant for a Letter of Credit,
(ii) may honor any presentation if the documents presented appear on their face substantially to
comply with the terms and conditions of the relevant Letter of Credit; (iii) may honor a previously
dishonored presentation under a Letter of Credit, whether such dishonor was pursuant to a court
order, to settle or compromise any claim of wrongful dishonor, or otherwise, and shall be entitled
to reimbursement to the same extent as if such presentation had initially been honored, together
with any interest paid by the Issuing Bank or its Affiliate; (iv) may honor any drawing that is
payable upon presentation of a statement advising negotiation or payment, upon receipt of such
statement (even if such statement indicates that a draft or other document is being delivered
separately), and shall not be liable for any failure of any such draft or other document to arrive,
or to conform in any way with the relevant Letter of Credit; (v) may pay any paying or negotiating
bank claiming that it rightfully honored under the laws or practices of the place where such bank
is located; and (vi) may settle or adjust any claim or demand made on the Issuing Bank or its
Affiliate in any way related to any order issued at the applicant’s request to an air carrier, a
letter of guarantee or of indemnity issued to a carrier or any similar document (each an “Order”)
and honor any drawing in connection with any Letter of Credit that is the subject of such Order,
notwithstanding that any drafts or other documents presented in connection with such Letter of
Credit fail to conform in any way with such Letter of Credit.

               In furtherance and extension and not in limitation of the specific provisions set forth above,
any action taken or omitted by the Agent under or in connection with the Letters of Credit issued
by it or any documents and certificates delivered thereunder, if taken or omitted in good faith,
shall not put the Agent under any resulting liability to the Borrower or any Bank.

          2.9.10 Cash Collateral Prior to the Expiration Date. 

               If any Letter of Credit is outstanding and such Letter of Credit (as it may have previously
been extended) has an expiration date which is after the Expiration Date, then Borrower shall Cash
Collateralize each such Letter of Credit in an amount equal to 100% of the face value of such
outstanding Letter of Credit, on or before the date which is seven (7) days

40

 

prior to the Expiration Date. Borrower hereby grants to Agent a security interest in all Cash
Collateral pledged pursuant to this Section 2.9 or otherwise under this Agreement.

          2.9.11 Issuing Bank Reporting Requirements.

          Each Issuing Bank shall, on the first business day of each month, provide to Agent and
Borrower a schedule of the Letters of Credit issued by it, in form and substance satisfactory to
Agent, showing the date of issuance of each Letter of Credit, the account party, the original face
amount (if any), and the expiration date of any Letter of Credit outstanding at any time during the
preceding month, and any other information relating to such Letter of Credit that the Agent may
request.

     2.10 Borrowings to Repay Swing Loans.

          PNC Bank may, at its option, exercisable at any time for any reason whatsoever, demand
repayment of the Swing Loans, and each Bank shall make a Revolving Credit Loan in an amount equal
to such Bank’s Ratable Share of the aggregate principal amount of the outstanding Swing Loans,
plus, if PNC Bank so requests, accrued interest thereon, provided that no Bank shall be obligated
in any event to make Revolving Credit Loans in excess of its Revolving Credit Commitment.
Revolving Credit Loans made pursuant to the preceding sentence shall bear interest at the Base Rate
Option and shall be deemed to have been properly requested in accordance with Section 2.5.1
[Revolving Credit Loan Requests] without regard to any of the requirements of that provision. PNC
Bank shall provide notice to the Banks (which may be telephonic or written notice by letter,
facsimile or telex) that such Revolving Credit Loans are to be made under this Section 2.10 and of
the apportionment among the Banks, and the Banks shall be unconditionally obligated to fund such
Revolving Credit Loans (whether or not the conditions specified in Section 2.5.1 [Revolving Credit
Loan Requests] are then satisfied) by the time PNC Bank so requests, which shall not be earlier
than 3:00 p.m. Pittsburgh time on the Business Day next after the date the Banks receive such
notice from PNC Bank.

     2.11 Increase in Revolving Credit Commitments.

          (i) Increasing Banks and New Banks. The Borrower may, at any time one year prior to the
Expiration Date, request that (1) the current Banks increase their Revolving Credit Commitments
(any current Bank which elects to increase its Revolving Credit Commitment shall be referred to as
an “Increasing Bank”) or (2) one or more new banks (each a “New Bank”) join this Agreement and
provide a Revolving Credit Commitment hereunder, subject to the following terms and conditions:

               (a) No Obligation to Increase. No current Bank shall be obligated to increase its Revolving
Credit Commitment and any increase in the Revolving Credit Commitment by any current Bank shall be
in the sole discretion of such current Bank.

               (b) Defaults. There shall exist no Events of Default or Potential Default on the effective
date of such increase after giving effect to such increase.

               (c) Aggregate Revolving Credit Commitments. After giving effect to such increase, the total
Revolving Credit Commitments shall not exceed $35,000,000.00.

41

 

               (d) Minimum Revolving Credit Commitments. After giving effect to such increase, the amount of
the Revolving Credit Commitments provided by each of the New Banks and each of the Increasing Banks
shall be at least $5,000,000.

               (e) Resolutions; Opinion. The Loan Parties shall deliver to the Agent on or before the
effective date of such increase the following documents in a form reasonably acceptable to the
Agent: (1) certifications of their corporate secretaries with attached resolutions certifying that
the increase in the Revolving Credit Commitment has been approved by such Loan Parties, and (2) an
opinion of counsel addressed to the Agent and the Banks addressing the authorization and execution
of the Loan Documents by, and enforceability of the Loan Documents against, the Loan Parties.

               (f) Notes. The Borrower shall execute and deliver (1) to each Increasing Bank a replacement
Revolving Credit Note reflecting the new amount of such Increasing Bank’s Revolving Credit
Commitment after giving effect to the increase (and the prior Revolving Credit Note issued to such
Increasing Bank shall be deemed to be terminated) and (2) to each New Bank a revolving credit Note
reflecting the amount of such New Bank’s Revolving Credit Commitment.

               (g) Approval of New Banks. Any New Bank shall be subject to the approval of the Agent.

               (h) Increasing Banks. Each Increasing Bank shall confirm its agreement to increase its
Revolving Credit Commitment pursuant to an acknowledgement in a form acceptable to the Agent,
signed by it and the Borrower and delivered to the Agent at least five (5) days before the
effective date of such increase.

               (i) New Banks—Joinder. Each New Bank shall execute a lender joinder in substantially the
form of Exhibit 2.11 pursuant to which such New Bank shall join and become a party to this
Agreement and the other Loan Documents with a Revolving Credit Commitment in the amount set forth
in such lender joinder.

          (ii) Treatment of Outstanding Loans and Letters of Credit.

               (a) Repayment of Outstanding Loans; Borrowing of New Loans. On the effective date of such
increase, the Borrower shall repay all Loans then outstanding, subject to the Borrower’s indemnity
obligations under Section 5.6.2 [Indemnity]; provided that it may borrow new Loans with a Borrowing
Date on such date. Each of the Banks shall participate in any new Loans made on or after such date
in accordance with their respective Ratable Shares after giving effect to the increase in Revolving
Credit Commitments contemplated by this Section.

               (b) Outstanding Letters of Credit. Repayment of Outstanding Loans; Borrowing of New Loans. On
the effective date of such increase, each Increasing Bank and each New Bank (i) will be deemed to
have purchased a participation in each then outstanding Letter of Credit equal to its Ratable Share
of such Letter of Credit and the participation of each other Bank in such Letter of Credit shall be
adjusted accordingly and (ii) will acquire, (and will pay to the Agent, for the account of each
Bank, in immediately available funds, an amount equal to) its Ratable Share of all outstanding
Participation Advances.

42

 

3. INTENTIONALLY OMITTED.

4. INTEREST RATES

     4.1 Interest Rate Options.

          The Borrower shall pay interest in respect of the outstanding unpaid principal amount of the
Loans as selected by it from the Base Rate Option or Libor-Rate Option set forth below applicable
to the Loans (provided that only the Base Rate Option shall apply to the Swing Loans), it being
understood that, subject to the provisions of this Agreement, the Borrower may select different
Interest Rate Options and different Interest Periods to apply simultaneously to the Loans
comprising different Borrowing Tranches and may convert to or renew one or more Interest Rate
Options with respect to all or any portion of the Loans comprising any Borrowing Tranche, provided
that there shall not be at any one time outstanding more than three (3) Borrowing Tranches in the
aggregate among all of the Loans and provided further that if an Event of Default or Potential
Default exists and is continuing, the Borrower may not request, convert to, or renew the LIBOR Rate
Option for any Loans and the Required Banks may demand that all existing Borrowing Tranches bearing
interest under the LIBOR Rate Option shall be converted immediately to the Base Rate Option,
subject to the obligation of the Borrower to pay any indemnity under Section 5.6.2 [Indemnity] in
connection with such conversion. If at any time the designated rate applicable to any Loan made by
any Bank exceeds such Bank’s highest lawful rate, the rate of interest on such Bank’s Loan shall be
limited to such Bank’s highest lawful rate.

          4.1.1 Revolving Credit Interest Rate Options.

               The Borrower shall have the right to select from the following Interest Rate Options
applicable to the Revolving Credit Loans (subject to the provisions above regarding Swing Loans):

          (i) Revolving Credit Base Rate Option: A fluctuating rate per annum (computed on the basis of
a year of 365 or 366 days, as the case may be, and actual days elapsed) equal to the Base Rate plus
0.50%, such interest rate to change automatically from time to time effective as of the effective
date of each change in the Base Rate; or

          (ii) Revolving Credit Libor-Rate Option: A rate per annum (computed on the basis of a year of
360 days and actual days elapsed) equal to the Libor-Rate plus 3.0%.

          4.1.2 Intentionally Omitted.

          4.1.3 Rate Quotations.

               The Borrower may call the Agent on or before the date on which a Loan Request is to be
delivered to receive an indication of the rates then in effect, but it is acknowledged that such
projection shall not be binding on the Agent or the Banks nor affect the rate of interest which
thereafter is actually in effect when the election is made.

     4.2 Interest Periods.

43

 

          At any time when the Borrower shall select, convert to or renew a Libor-Rate Option, the
Borrower shall notify the Agent thereof at least three (3) Business Days prior to the effective
date of such Libor-Rate Option by delivering a Loan Request. The notice shall specify an Interest
Period during which such Interest Rate Option shall apply. Notwithstanding the preceding sentence,
the following provisions shall apply to any selection of, renewal of, or conversion to a Libor-Rate
Option:

          4.2.1 Amount of Borrowing Tranche.

               each Borrowing Tranche of Libor-Rate Loans shall be in integral multiples of $500,000 and not
less than $1,000,000;

          4.2.2 Renewals.

               in the case of the renewal of a Libor-Rate Option at the end of an Interest Period, the first
day of the new Interest Period shall be the last day of the preceding Interest Period, without
duplication in payment of interest for such day.

     4.3 Interest After Default.

          To the extent permitted by Law, upon the occurrence of an Event of Default and until such time
such Event of Default shall have been cured or waived:

          4.3.1 Letter of Credit Fees, Interest Rate.

               the Letter of Credit Fees and the rate of interest for each Loan otherwise applicable pursuant
to Section 2.9.2 [Letter of Credit Fees] or Section 4.1 [Interest Rate Options], respectively,
shall be increased by 2.0% per annum; and

          4.3.2 Other Obligations.

               each other Obligation hereunder if not paid when due shall bear interest at a rate per annum
equal to the sum of the rate of interest applicable under the Revolving Credit Base Rate Option
plus an additional 2.0% per annum from the time such Obligation becomes due and payable and until
it is paid in full.

          4.3.3 Acknowledgment.

               The Borrower acknowledges that the increase in rates referred to in this Section 4.3 reflects,
among other things, the fact that such Loans or other amounts have become a substantially greater
risk given their default status and that the Banks are entitled to additional compensation for such
risk; and all such interest shall be payable by Borrower upon demand by Agent.

     4.4 Libor-Rate Unascertainable; Illegality; Increased Costs; Deposits Not Available.

          4.4.1 Unascertainable.

               If on any date on which a Libor-Rate would otherwise be determined, the Agent shall have
determined that:

44

 

          (i) adequate and reasonable means do not exist for ascertaining such Libor-Rate, or

          (ii) a contingency has occurred which materially and adversely affects the London interbank
eurodollar market relating to the Libor-Rate, then the Agent shall have the rights specified in
Section 4.4.3 [Agent’s and Bank’s Rights].

          4.4.2 Illegality; Increased Costs; Deposits Not Available.

               If at any time any Bank shall have determined that:

          (i) the making, maintenance or funding of any Loan to which a Libor-Rate Option applies has
been made impracticable or unlawful by compliance by such Bank in good faith with any Law or any
interpretation or application thereof by any Official Body or with any request or directive of any
such Official Body (whether or not having the force of Law), or

          (ii) such Libor-Rate Option will not adequately and fairly reflect the cost to such Bank of
the establishment or maintenance of any such Loan, or

          (iii) after making all reasonable efforts, deposits of the relevant amount in Dollars for the
relevant Interest Period for a Loan, or to banks generally, to which a Libor-Rate Option applies,
respectively, are not available to such Bank with respect to such Loan, or to banks generally, in
the interbank eurodollar market, then the Agent shall have the rights specified in Section 4.4.3
[Agent’s and Bank’s Rights].

          4.4.3 Agent’s and Bank’s Rights.

               In the case of any event specified in Section 4.4.1 [Unascertainable] above, the Agent shall
promptly so notify the Banks and the Borrower thereof, and in the case of an event specified in
Section 4.4.2 [Illegality; Increased Costs; Deposits Not Available] above, such Bank shall promptly
so notify the Agent and endorse a certificate to such notice as to the specific circumstances of
such notice, and the Agent shall promptly send copies of such notice and certificate to the other
Banks and the Borrower. Upon such date as shall be specified in such notice (which shall not be
earlier than the date such notice is given), the obligation of (A) the Banks, in the case of such
notice given by the Agent, or (B) such Bank, in the case of such notice given by such Bank, to
allow the Borrower to select, convert to or renew a Libor-Rate Option shall be suspended until the
Agent shall have later notified the Borrower, or such Bank shall have later notified the Agent, of
the Agent’s or such Bank’s, as the case may be, determination that the circumstances giving rise to
such previous determination no longer exist. If at any time the Agent makes a determination under
Section 4.4.1 [Unascertainable] and the Borrower has previously notified the Agent of its selection
of, conversion to or renewal of a Libor-Rate Option and such Interest Rate Option has not yet gone
into effect, such notification shall be deemed to provide for selection of, conversion to or
renewal of the Base Rate Option otherwise available with respect to such Loans. If any Bank
notifies the Agent of a determination under Section 4.4.2 [Illegality; Increased Costs; Deposits
Not Available], the Borrower shall, subject to the Borrower’s indemnification Obligations under
Section 5.6.2 [Indemnity], as to any Loan of the Bank to which a Libor-Rate Option applies, on the
date specified in such notice either convert such Loan to the Base Rate Option otherwise available
with respect to such Loan or prepay such Loan in accordance with Section 5.4 [Voluntary
Prepayments]. Absent due notice

45

 

from the Borrower of conversion or prepayment, such Loan shall automatically be converted to
the Base Rate Option otherwise available with respect to such Loan upon such specified date.

     4.5 Selection of Interest Rate Options.

          If the Borrower fails to select a new Interest Period to apply to any Borrowing Tranche of
Loans under the Libor-Rate Option at the expiration of an existing Interest Period applicable to
such Borrowing Tranche in accordance with the provisions of Section 4.2 [Interest Periods], the
Borrower shall be deemed to have converted such Borrowing Tranche to the Base Rate Option,
commencing upon the last day of the existing Interest Period.

5. PAYMENTS

     5.1 Payments.

          All payments and prepayments to be made in respect of principal, interest, Commitment Fees,
Letter of Credit Fees, Agent’s Fee or other fees or amounts due from the Borrower hereunder shall
be payable prior to 11:00 a.m., Pittsburgh time, on the date when due without presentment, demand,
protest or notice of any kind, all of which are hereby expressly waived by the Borrower, and
without set-off, counterclaim or other deduction of any nature, and an action therefor shall
immediately accrue. Such payments shall be made to the Agent at the Principal Office for the
account of PNC Bank with respect to Swing Loans and for the ratable accounts of the Banks with
respect to the Revolving Credit Loans in U.S. Dollars and in immediately available funds, and the
Agent shall promptly distribute such amounts to the Banks in immediately available funds, provided
that in the event payments are received by 11:00 a.m., Pittsburgh time, by the Agent with respect
to the Loans and such payments are not distributed to the Banks on the same day received by the
Agent, the Agent shall pay the Banks the Federal Funds Effective Rate with respect to the amount of
such payments for each day held by the Agent and not distributed to the Banks. The Agent’s and
each Bank’s statement of account, ledger or other relevant record shall, in the absence of manifest
error, be conclusive as the statement of the amount of principal of and interest on the Loans and
other amounts owing under this Agreement and shall be deemed an “account stated.”

     5.2 Pro Rata Treatment of Banks.

          Each borrowing shall be allocated to each Bank according to its Ratable Share, and each
selection of, conversion to or renewal of any Interest Rate Option and each payment or prepayment
by the Borrower with respect to principal, interest, Commitment Fees, Letter of Credit Fees, or
other fees (except for the Agent’s Fee) or amounts due from the Borrower hereunder to the Banks
with respect to the Loans, shall (except as provided in Section 4.4.3 [Agent’s and Bank’s Rights]
in the case of an event specified in Section 4.4 [Libor-Rate Unascertainable; Etc.], 5.4.2
[Replacement of a Bank] or 5.6 [Additional Compensation in Certain Circumstances]) be made in
proportion to the applicable Loans outstanding from each Bank and, if no such Loans are then
outstanding, in proportion to the Ratable Share of each Bank. Notwithstanding any of the
foregoing, each borrowing or payment or prepayment by the Borrower of principal, interest, fees or
other amounts from the Borrower with respect to Swing Loans shall be made by or to PNC Bank
according to Section 2 [Revolving Credit and Swing Loan Facilities].

46

 

     5.3 Interest Payment Dates.

          Interest on Loans to which the Base Rate Option applies shall be due and payable in arrears on
the last Business Day of each June, September, December and March after the date hereof and on the
Expiration Date or upon acceleration of the Notes. Interest on Loans to which the Libor-Rate
Option applies shall be due and payable on the last day of each Interest Period for those Loans
and, if such Interest Period is longer than three (3) Months, also on the 90th day of such Interest
Period. Interest on mandatory prepayments of principal under Section 5.5 [Mandatory Prepayments]
shall be due on the date such mandatory prepayment is due. Interest on the principal amount of
each Loan or other monetary Obligation shall be due and payable on demand after such principal
amount or other monetary Obligation becomes due and payable (whether on the stated maturity date,
upon acceleration or otherwise).

     5.4 Voluntary Prepayments.

          5.4.1 Right to Prepay.

               The Borrower shall have the right at its option from time to time to prepay the Loans in whole
or part without premium or penalty (except as provided in Section 5.4.2 below or in Section 5.6
[Additional Compensation in Certain Circumstances]):

          (i) at any time with respect to any Loan to which the Base Rate Option applies,

          (ii) on the last day of the applicable Interest Period with respect to Loans to which a
Libor-Rate Option applies,

          (iii) on the date specified in a notice by any Bank pursuant to Section 4.4 [Libor-Rate
Unascertainable, Etc.] with respect to any Loan to which a Libor-Rate Option applies.

               Whenever the Borrower desires to prepay any part of the Loans, it shall provide a prepayment
notice to the Agent by 1:00 p.m. on the date of prepayment of the Revolving Credit Loans and no
later than 2:00 p.m., Pittsburgh time, on the date of prepayment of Swing Loans, setting forth the
following information:

          (x) the date, which shall be a Business Day, on which the proposed prepayment is to be made;

          (y) a statement indicating the application of prepayment between Swing Loans and Revolving
Loans; and

          (z) the total principal amount of such prepayment, which shall not be less than $100,000 for
any Swing Loan or $500,000 for any Revolving Credit Loan; provided however, such prepayment may be
less than such amounts if such prepayment pays in full all outstanding amounts under the Swing
Loans or Revolving Credit Loans, as applicable.

               All prepayment notices shall be irrevocable. The principal amount of the Loans for which a
prepayment notice is given, together with interest on such principal amount except with respect to
Loans to which the Base Rate Option applies, shall be due and payable on

47

 

the date specified in such prepayment notice as the date on which the proposed prepayment is
to be made. Except as provided in Section 4.4.3 [Agent’s and Bank’s rights], if the Borrower
prepays a Loan but fails to specify the applicable Borrowing Tranche which the Borrower is
prepaying, the prepayment shall be applied first to Loans to which the Base Rate Option applies,
then to Loans to which the Libor-Rate Option applies. Any prepayment hereunder shall be subject to
the Borrower’s Obligation to indemnify the Banks under Section 5.6.2 [Indemnity].

          5.4.2 Replacement of a Bank.

          In the event any Bank (i) gives notice under Section 4.4 [LIBOR Rate Unascertainable, Etc.],
(ii) requests compensation under Section 4.4 [LIBOR Rate Unascertainable, Etc.], or requires the
Borrower to pay any additional amount to any Bank or any Official Body for the account of any Bank
pursuant to Section 5.6 [Additional Compensation in Certain Circumstances], (iii) is a
Non-Complying Bank or otherwise, (iv) becomes subject to the control of an Official Body (other
than normal and customary supervision), or (v) is a Non-Consenting Bank referred to in Section 11.1
[Modifications, Amendments or Waivers] then in any such event the Borrower may, at its sole
expense, upon notice to such Bank and the Agent, require such Bank to assign and delegate, without
recourse (in accordance with and subject to the restrictions contained in, and consents required
by, Section 11.11 [Successors and Assigns]), all of its interests, rights and obligations under
this Agreement and the related Loan Documents to an assignee that shall assume such obligations
(which assignee may be another Bank, if a Bank accepts such assignment), provided that:

          (i) the Borrower shall have paid to the Agent the assignment fee specified in Section 11.11
[Successors and Assigns];

          (ii) such Bank shall have received payment of an amount equal to the outstanding principal of
its Loans and Participation Advances, accrued interest thereon, accrued fees and all other amounts
payable to it hereunder and under the other Loan Documents (including any amounts under Section
5.6.2 [Indemnity]) from the assignee (to the extent of such outstanding principal and accrued
interest and fees) or the Borrower (in the case of all other amounts);

          (iii) in the case of any such assignment resulting from a claim for compensation under
Section 5.6.1 [Increased Costs Generally] or payments required to be made pursuant to Section 11.3
[Taxes], such assignment will result in a reduction in such compensation or payments thereafter;
and

          (iv) such assignment does not conflict with applicable Law.

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

          5.4.3 Change of Lending Office.

               Each Bank agrees that upon the occurrence of any event giving rise to increased costs or other
special payments under Section 4.4.2 [Illegality, Etc.] or 5.6.1 [Increased Costs, Etc.] with
respect to such Bank, it will if requested by the Borrower, use reasonable

48

 

efforts (subject to overall policy considerations of such Bank) to designate another lending
office for any Loans or Letters of Credit affected by such event, provided that such designation is
made on such terms that such Bank and its lending office suffer no economic, legal or regulatory
disadvantage, with the object of avoiding the consequence of the event giving rise to the operation
of such Section. Nothing in this Section shall affect or postpone any of the Obligations of the
Borrower or any other Loan Party or the rights of the Agent or any Bank provided in this Agreement.

     5.5 Mandatory Prepayments.

          (i) Promptly (and in any event within three Business Days) after any officer of the Borrower
obtains knowledge of any Prepayment Event or any action of the Borrower or any other Person that
may be reasonably likely to result in a Prepayment Event, notice thereof in the form of an
Officer’s Certificate describing in reasonable detail the facts and circumstances giving rise to
such Prepayment Event or potential Prepayment Event, specifying the date such Prepayment Event
occurred or is expected to occur, and making reference to this Section and the right of the Banks
to require the prepayment of the Loans on the terms and conditions provided for in said Section.

          (ii) Change in Control. At any time following the occurrence of a Prepayment Event (subject
to the penultimate sentence of this Section 5.5(ii)), the Agent shall have the right at its option,
exercisable by the giving of notice to the Borrower (a “Prepayment Election Notice”), to elect to
require the prepayment by the Borrower of all Loans on the prepayment date specified by Agent in
such Prepayment Election Notice (which shall not in any event be less than 30 days nor more than 60
days after the date on which such holder shall have given such Prepayment Election Notice to the
Borrower). On the prepayment date specified in any Prepayment Election Notice given by Agent, the
Borrower will prepay all Loans. The right of the Agent to give a Prepayment Election Notice for
the prepayment of the Loans pursuant to this Section following a Prepayment Event shall expire at
the close of business in New York City on the one hundred-twentieth day following the later of (x)
the date of such Prepayment Event and (y) actual receipt by Agent of notice of such Prepayment
Event pursuant to Section 5.5(i). Notwithstanding any provision hereof to the contrary, no failure
on the part of the Agent to exercise its right to require the prepayment thereof by the Borrower
pursuant to this Section 5.5(ii) following a Prepayment Event shall be deemed a waiver of or
otherwise impair the rights of Agent pursuant to this Section 5.5(ii) in respect of any other
events or circumstances constituting a Prepayment Event.

          (a) “Prepayment Event” shall mean (i) any Loan Party’s Change in Control, or (ii) any
Control Event with respect to the Borrower or any of the other Loan Parties or (iii) any
Parent Change in Control with respect to the Parent.

          (b) “Borrower’s’ Change in Control” shall be deemed to have occurred if there is any
change subsequent to the Closing Date in the Persons (as such term is used in Section 13(d)
and Section 14(d)(2) of the Exchange Act as in effect on the Closing Date) who are direct
owners of an equity interest in the Borrower or any of the other Loan Parties.

          (c) “Control Event” means:

49

 

          (i) the execution by the Parent or any of its Subsidiaries or Affiliates, or
the Borrower or any of its Subsidiaries or Affiliates, of any agreement with
respect to any proposed transaction or event or series of transactions or events
which, individually or in the aggregate, may reasonably be expected to result in a
Parent Change in Control or an Borrowers’ Change in Control, or

          (ii) the execution of any written agreement which, when fully performed by the
parties thereto, would result in a Parent Change in Control or a Loan Party’s Change
in Control.

     5.6 Additional Compensation in Certain Circumstances.

          5.6.1 Increased Costs or Reduced Return Resulting from Taxes, Reserves, Capital Adequacy
Requirements, Expenses, Etc.

               If any Law, guideline or interpretation or any change in any Law, guideline or interpretation
or application thereof by any Official Body charged with the interpretation or administration
thereof or compliance with any request or directive (whether or not having the force of Law) of any
central bank or other Official Body:

          (i) subjects any Bank to any tax or changes the basis of taxation with respect to this
Agreement, the Notes, the Loans or payments by the Borrower of principal, interest, Commitment
Fees, or other amounts due from the Borrower hereunder or under the Notes (except for taxes on the
overall net income of such Bank),

          (ii) imposes, modifies or deems applicable any reserve, special deposit or similar requirement
against credits or commitments to extend credit extended by, or assets (funded or contingent) of,
deposits with or for the account of, or other acquisitions of funds by, any Bank, or

          (iii) imposes, modifies or deems applicable any capital adequacy or similar requirement
(A) against assets (funded or contingent) of, or letters of credit, other credits or commitments to
extend credit extended by, any Bank, or (B) otherwise applicable to the obligations of any Bank
under this Agreement,

and the result of any of the foregoing is to increase the cost to, reduce the income receivable by,
or impose any expense (including loss of margin) upon any Bank with respect to this Agreement, the
Notes or the making, maintenance or funding of any part of the Loans (or, in the case of any
capital adequacy or similar requirement, to have the effect of reducing the rate of return on any
Bank’s capital, taking into consideration such Bank’s customary policies with respect to capital
adequacy) by an amount which such Bank in its sole discretion deems to be material, such Bank shall
from time to time notify the Borrower and the Agent of the amount determined in good faith (using
any averaging and attribution methods employed in good faith) by such Bank to be necessary to
compensate such Bank for such increase in cost, reduction of income, additional expense or reduced
rate of return. Such notice shall set forth in reasonable detail the basis for such determination.
Such amount shall be due and payable by the Borrower to such Bank ten (10) Business Days after
such notice is given.

50

 

          5.6.2 Indemnity.

               In addition to the compensation required by Section 5.6.1 [Increased Costs, Etc.], the
Borrower shall indemnify each Bank against all liabilities, losses or expenses (including loss of
margin, any loss or expense incurred in liquidating or employing deposits from third parties and
any loss or expense incurred in connection with funds acquired by a Bank to fund or maintain Loans
subject to a Libor-Rate Option) which such Bank sustains or incurs as a consequence of any

          (i) payment, prepayment, conversion or renewal of any Loan to which a Libor-Rate Option
applies on a day other than the last day of the corresponding Interest Period (whether or not such
payment or prepayment is mandatory, voluntary or automatic and whether or not such payment or
prepayment is then due),

          (ii) attempt by the Borrower to revoke (expressly, by later inconsistent notices or otherwise)
in whole or part any Loan Requests under Section 2.5 [Revolving Credit Loan Requests] or
Section 4.2 [Interest Periods] or notice relating to prepayments under Section 5.4 [Voluntary
Prepayments], or

          (iii) default by the Borrower in the performance or observance of any covenant or condition
contained in this Agreement or any other Loan Document, including any failure of the Borrower to
pay when due (by acceleration or otherwise) any principal, interest, Commitment Fee or any other
amount due hereunder.

          If any Bank sustains or incurs any such loss or expense, it shall from time to time notify the
Borrower of the amount determined in good faith by such Bank (which determination may include such
assumptions, allocations of costs and expenses and averaging or attribution methods as such Bank
shall deem reasonable) to be necessary to indemnify such Bank for such loss or expense. Such
notice shall set forth in reasonable detail the basis for such determination. Such amount shall be
due and payable by the Borrower to such Bank ten (10) Business Days after such notice is given.

          5.6.3 Borrowing Base Exceeded.

          In the event that at any time the Revolving Facility Usage shall exceed the Borrowing Base,
the Borrower shall immediately make a mandatory payment of principal to the Agent in an amount
equal to or greater than such amount as shall be necessary to cause the Revolving Facility Usage to
be less than the Borrowing Base, and the Agent shall apply such payment to the Revolving Credit
Loans of the Banks based upon their Revolving Credit Ratable Share.

     5.7 Settlement Date Procedures.

          In order to minimize the transfer of funds between the Banks and the Agent, the Borrower may
borrow, repay and reborrow Swing Loans and PNC Bank may make Swing Loans as provided during the
period between Settlement Dates. Not later than 12:00 p.m. on each Settlement Date, the Agent
shall notify each Bank of its Ratable Share of the total of the Revolving Credit Loans and the
Swing Loans (each a “Required Share”). Prior to 3:00 p.m., Pittsburgh time, on such Settlement
Date, each Bank shall pay to the Agent the amount equal to

51

 

the difference between its Required Share and its Revolving Credit Loans, and the Agent shall
pay to each Bank its Ratable Share of all payments made by the Borrower to the Agent with respect
to the Revolving Credit Loans. The Agent shall also effect settlement in accordance with the
foregoing sentence on the proposed Borrowing Dates for Revolving Credit Loans and on the date any
mandatory prepayment is due under this Agreement and may at its option effect settlement on any
other Business Day. These settlement procedures are established solely as a matter of
administrative convenience, and nothing contained in this Section 5.7 shall relieve the Banks of
their obligations to fund Revolving Credit Loans on dates other than a Settlement Date. The Agent
may at any time at its option for any reason whatsoever require each Bank to pay immediately to the
Agent such Bank’s Ratable Share of the outstanding Revolving Credit Loans and each Bank may at any
time require the Agent to pay immediately to such Bank its Ratable Share of all payments made by
the borrower to the Agent with respect to the Revolving Credit Loans.

     5.8 Presumptions by Agent.

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

     5.9 Interest Payment Dates. 

               Interest on Loans to which the Base Rate Option applies shall be due and payable in arrears on
each Payment Date. Interest on Loans to which the LIBOR Rate Option applies shall be due and
payable on the last day of each Interest Period for those Loans and, if such Interest Period is
longer than three (3) Months, also on the 90th day of such Interest Period. Interest on mandatory
prepayments of principal under Section 5.5 [Mandatory Prepayments] shall be due on the date such
mandatory prepayment is due. Interest on the principal amount of each Loan or other monetary
Obligation shall be due and payable on demand after such principal amount or other monetary
Obligation becomes due and payable (whether on the stated Expiration Date, upon acceleration or
otherwise).

6. REPRESENTATIONS AND WARRANTIES

     6.1 Representations and Warranties.

          The Borrower and each Guarantor, jointly and severally, represent and warrant to the Agent and
each of the Banks as follows:

          6.1.1 Organization and Qualification.

52

 

               The Borrower is a limited liability company, and each other Loan Party is a corporation duly
organized, validly existing and in good standing under the laws of its jurisdiction of
organization. Each Loan Party has the lawful power to own or lease its properties and to engage in
the business it presently conducts or proposes to conduct. Each Loan Party is duly licensed or
qualified and in good standing in each jurisdiction listed with respect to it on Schedule
6.1.1 and in all other jurisdictions where the property owned or leased by it or the nature of
the business transacted by it or both makes such licensing or qualification necessary; provided,
however, no Loan Party shall be in breach of this Section in the event that a Loan Party
inadvertently failed to obtain or maintain a qualification or license so long as such failure (i)
either alone or when considered together with all other such failures, has not resulted and could
not reasonably be expected to result in a Material Adverse Change, (ii) is promptly remedied upon a
Loan Party becoming aware of such failure and (iii) does not adversely affect any material portion
of the Collateral.

          6.1.2 Capitalization and Ownership.

               All of the member interests in the Borrower (the “Member Interests”) are owned as indicated on
Schedule 6.1.2. All of the Member Interests have been validly issued and are fully paid
and are nonassessable. There are no options, warrants or other rights outstanding to purchase any
such Member Interests except as indicated on Schedule 6.1.2.

          6.1.3 Subsidiaries.

               Schedule 6.1.3 states (i) the name of each of the Borrower’s Subsidiaries, (ii) each
such Subsidiary’s jurisdiction of incorporation or formation, (iii) its authorized capital stock,
and the issued and outstanding shares (referred to herein as the “Subsidiary Shares”) if it is a
corporation, its outstanding partnership interests (referred to herein as “Partnership Interests”)
if it is a partnership and its outstanding limited liability company interests, interest assigned
to managers thereof and voting rights associated therewith (the “LLC Interests” and together with
the Subsidiary Shares and the Partnership Interests, the “Subsidiary Ownership Interests”) if it is
a limited liability company, and (iv) the owner of all such Subsidiary’s Ownership Interests. The
Borrower and each Subsidiary of the Borrower has good and marketable title to all of the Subsidiary
Ownership Interests it purports to own, free and clear in each case of any Lien other than
Permitted Liens. All Subsidiary Ownership Interests have been validly issued, and all Subsidiary
Ownership Interests are fully paid and nonassessable. There are no options, warrants or other
rights outstanding to purchase any such Subsidiary Ownership Interests. No Subsidiary is a party
to, or otherwise subject to any legal, regulatory, contractual or other restriction (other than (i)
this Agreement, (ii) customary limitations imposed by corporate law statutes and (iii) in the case
of TWCC, the NRGT Documents) restricting the ability of such Subsidiary to pay dividends out of
profits or make any other similar distributions of profits to the Borrower or any of its
Subsidiaries that owns any Subsidiary Ownership Interests of such Subsidiary.

          6.1.4 Power and Authority.

               Each Loan Party has full power to enter into, execute, deliver and carry out this Agreement
and the other Loan Documents to which it is a party, to incur the Indebtedness contemplated by the
Loan Documents and to perform its Obligations under the Loan Documents to which it is a party, and
all such actions have been duly authorized by all

53

 

necessary proceedings on its part (including all necessary action, if any, on the part of the
owners of its Subsidiary Ownership Interests).

          6.1.5 Validity and Binding Effect.

               This Agreement has been duly authorized and validly executed and delivered by each Loan Party,
and each other Loan Document which any Loan Party is required to execute and deliver on or after
the date hereof will have been duly authorized, executed and delivered by such Loan Party on or
prior to the Closing Date. This Agreement and each other Loan Document constitutes, or will
constitute, a legal, valid and binding obligation of each Loan Party which is or will be a party
thereto on and after its date of delivery thereof, enforceable against such Loan Party in
accordance with its terms, except to the extent that enforceability of this Agreement or any such
other Loan Document may be limited by bankruptcy, insolvency, reorganization, moratorium or other
similar laws affecting the enforceability of creditors’ rights generally or by general equitable
principles limiting the availability of the right of specific performance or other equitable
remedies.

          6.1.6 No Conflict.

               Neither the execution and delivery of this Agreement or the other Loan Documents by any Loan
Party nor the consummation of the transactions herein or therein contemplated nor compliance with
the terms and provisions hereof or thereof by any Loan Party will conflict with, constitute a
default under or result in any breach of (i) the terms and conditions of the Organizational
Documents of any Loan Party or (ii) any Law or any material Coal Supply Contract, Coal Lease or
other agreement or instrument or any order, writ, judgment, injunction or decree to which any Loan
Party or any of its Subsidiaries is a party or by which it or any of its Subsidiaries is bound or
to which it is subject, or result in the creation or enforcement of any Lien, charge or encumbrance
whatsoever upon any property (now or hereafter acquired) of any Loan Party or any of its
Subsidiaries (other than Liens granted under the Loan Documents and Liens granted under the Note
Purchase Documents).

          6.1.7 Litigation.

               There are no actions, suits, proceedings or investigations pending or, to the knowledge of the
Borrower or any Guarantors, threatened against any Loan Party or any Subsidiary of such Loan Party
at law or equity before any Official Body, except those described on Schedule 6.1.7, none
of which individually or in the aggregate could be reasonably expected to result in any Material
Adverse Change. None of the Loan Parties or any Subsidiaries of any Loan Party is in violation of
any order, writ, injunction or decree of any Official Body (including without limitation
Environmental Laws or the USA Patriot Act) which either individually or in the aggregate could
reasonably be expected to result in a Material Adverse Change.

          6.1.8 Title to Properties.

               Schedule 6.1.8 identifies all of the real property interests, both owned and leased,
of the Loan Parties and sets forth, with respect to each such real property interest the name of
the Loan Party which is the owner or lessee thereof, as the case may be, and, if leased, the name
of the owner and lessor thereof. Each Loan Party and each Subsidiary of each Loan Party has good
and marketable title to all real estate owned by it and a valid leasehold interest in

54

 

all properties, assets and other rights which it purports to lease or which are reflected as
owned or leased on its books and records, free and clear of all Liens and encumbrances except
Permitted Liens, and subject to the terms and conditions of the applicable leases; provided,
however, a Loan Party shall not be in breach of the foregoing in the event that (i) it fails to own
a valid leasehold interest which, either considered alone or together with all other such valid
leaseholds which it fails to own, is not material to the continued operations of such Loan Party
as contemplated by the Financial Projections or its mining plan as in effect on the Closing Date or
(ii) the Loan Party’s interest in a leasehold is less than fully marketable because the consent of
the lessor to future assignments has not been obtained. All leases of property which are material
to the continued operations of each Loan Party as contemplated by the Financial Projections and its
mining plan as in effect on the Closing Date are in full force and effect without the necessity for
any consent which has not previously been obtained.

          6.1.9 Financial Statements.

          (i) Historical Statements. The Borrower has delivered to each Bank copies of (a) the audited
consolidated year-end financial statements of the Borrower and its Subsidiaries described in item 1
of Schedule 6.1.9 (the “Annual Statements”), and (b) the unaudited consolidated interim
financial statements of the Borrower and its Subsidiaries described in item 2 of Schedule
6.1.9 (the “Interim Statements” and, together with the Annual Statements, the “Historical
Statements”). The Historical Statements (including in each case the related schedules and notes)
fairly present in all material respects the consolidated financial position of the Borrower and its
Subsidiaries as of the respective dates specified in Schedule 6.1.9 and the consolidated
results of their operations and cash flows for the respective periods so specified and have been
prepared in accordance with GAAP consistently applied throughout the periods involved except as
specified in the notes thereto (subject, in the case of the Interim Statements, to normal year-end
adjustments and the absence of footnotes). Neither the restatement by Parent of its consolidated
financial statements as at the end of and for the fiscal year ended December 31, 2006, as set forth
in Parent’s report on Form 10-K/A, Amendment No. 2 to Form 10-K, for such fiscal year, or as at the
end of and for the respective fiscal quarters ended March 31, 2007 and June 30, 2007, as set forth
in Parent’s reports on Form 10-Q/A, Amendment No. 1 to Form 10-Q, for such respective fiscal
quarters, nor the restatement by the Borrower of its consolidated financial statements as at the
end of and for the fiscal year of the Borrower ended December 31, 2006 nor the events and
circumstances necessitating any of such restatements, have resulted or could reasonably be expected
to result in a Material Adverse Change.

          (ii) Financial Projections. The Borrower has delivered to each Bank copies of the Financial
Projections. The Financial Projections represent a reasonable range of possible results in light
of the history of the business, present and foreseeable conditions and the intentions of the
Borrower’s management. The Financial Projections represent the Borrower’s good faith estimate of
future performance based upon historical financial information and upon assumptions which were
reasonable at the time of the preparation thereof and which remain reasonable as of the date
hereof.

          (iii) Accuracy of Financial Statements; Material Liabilities. Except for liabilities arising
in the ordinary course of business and the Indebtedness arising in connection with the Notes and
the Note Purchase Documents since the date of the last Historical Statement, neither the Borrower
nor any Subsidiary of the Borrower has incurred any liabilities, contingent or otherwise, or
forward or long-term commitments that are not disclosed in the Historical

55

 

Statements or in the notes thereto or on Schedule 6.1.9, and except as disclosed
therein there are no unrealized or anticipated losses from any commitments of the Borrower or any
Subsidiary of the Borrower which either individually or in the aggregate could reasonably be
expected to result in a Material Adverse Change. Since December 31, 2007, no Material Adverse
Change has occurred. As of the Closing Date, the Borrower and its Subsidiaries do not have any
material liabilities that are not disclosed on the Historical Statements or in the other Disclosure
Documents.

          6.1.10 Use of Proceeds; Margin Stock.

               6.1.10.1 General.

                    The Loan Parties intend to use the proceeds of the Loans in accordance with Sections 2.8 and
8.1.11.

               6.1.10.2 Margin Stock.

                    None of the Loan Parties or any Subsidiaries of any Loan Party engages or intends to engage
principally, or as one of its important activities, in the business of extending credit for the
purpose, immediately, incidentally or ultimately, of purchasing or carrying margin stock (within
the meaning of Regulation U). No part of the proceeds of any Loan or any sale of the Term Notes
under the Note Purchase Agreement has been or will be used, immediately, incidentally or
ultimately, to purchase or carry any margin stock or to extend credit to others for the purpose of
purchasing or carrying any margin stock or to refund Indebtedness originally incurred for such
purpose, or for any purpose which entails a violation of or which is inconsistent with the
provisions of the regulations of the Board of Governors of the Federal Reserve System. None of the
Loan Parties or any Subsidiary of any Loan Party holds or intends to hold margin stock in such
amounts that more than 10% of the reasonable value of the assets of any Loan Party or Subsidiary of
any Loan Party are or will be represented by margin stock.

               6.1.10.3 Section 20 Subsidiaries.

                    The Loan Parties do not intend to use and shall not use any portion of the proceeds of the
Loans, directly or indirectly, to purchase during the underwriting period, or for thirty (30) days
thereafter, Ineligible Securities being underwritten by a Section 20 Subsidiary.

          6.1.11 Full Disclosure.

               The Borrower, through its agent, PNC Capital Markets LLC, has delivered to the Banks a copy of
a Confidential Offering Memorandum, dated February, 2008 (the “Memorandum”), relating to the
transactions contemplated hereby. The Memorandum fairly describes, in all material respects, the
general nature of the business and principal properties of the Borrower and its Subsidiaries. This
Agreement (including the schedules hereto), the Memorandum, the documents, certificates or other
writings delivered to the Banks by or on behalf of any Loan Party in connection with the
transactions contemplated hereby (including, without limitation, a report entitled “Westmoreland
Mining LLC Business Plan Reasonableness Review”, dated February 14, 2008, prepared by Norwest
Corporation) and the financial

56

 

statements listed in Schedule 6.1.9 (collectively the “Disclosure Documents”), taken
as a whole, do not contain any untrue statement of a material fact or omit to state any material
fact necessary to make the statements therein not misleading in light of the circumstances under
which they were made. Except as disclosed in the Disclosure Documents, since December 31, 2007,
there has been no change in the financial condition, operations, business, properties or prospects
of the Borrower or any Subsidiary except changes which, neither individually nor in the aggregate,
constitute or could reasonably be expected to constitute or give rise to a Material Adverse Change.
There is no fact known to any Loan Party that could reasonably be expected to constitute or give
rise to a Material Adverse Change that has not been set forth in the Disclosure Documents. As of
the Closing Date, the Borrower and its Subsidiaries do not have any material liabilities that are
not disclosed in this Agreement or in the Disclosure Documents.

          6.1.12 Taxes.

               Except as described on Schedule 6.1.12, all federal, state, local and other tax
returns required to have been filed with respect to each Loan Party and each Subsidiary of each
Loan Party have been filed, and payment or adequate provision for the payment of all taxes, fees,
assessments and other governmental charges which have or may become due pursuant to said returns or
to assessments received has been made, except to the extent that such taxes, fees, assessments and
other charges are being contested in good faith by appropriate proceedings diligently conducted and
for which such reserves or other appropriate provision, if any, as shall be required by GAAP shall
have been made. As of the date hereof, there are no agreements or waivers extending the statutory
period of limitations applicable to any federal income tax return of any Loan Party or Subsidiary
of any Loan Party for any period.

          6.1.13 Consents and Approvals.

               Except for the filing of the financing statements and the Mortgages (Noteholders) in the
appropriate state and county filing offices, and filings with the U.S. Patent and Trademark Office
and the U.S. Copyright Office, no consent, approval, exemption, order or authorization of, or a
registration or filing with, any Official Body or any other Person is required by any Law or any
agreement in connection with the execution, delivery and performance by any Loan Party of this
Agreement and the other Loan Documents, other than those which shall have been obtained or made on
or prior to the Closing Date, except as listed on Schedule 6.1.13 Except for consents,
approvals, exemptions, orders or authorizations, and registrations or filings that are obtainable
or may be made in the ordinary course of business of the Loan Parties without significant expense
or delay, no consent, approval, exemption, order or authorization of, or registration or filing
with, any Official Body or any other Person is required by any Law or any agreement material to the
business of any Loan Party in connection with the conduct by each Loan Party of its business.

          6.1.14 No Event of Default; Compliance with Instruments.

               No event has occurred and is continuing and no condition exists or will exist after giving
effect to the issue and sale of the Notes and the incurrence of Indebtedness evidenced thereby
pursuant to the Note Purchase Agreement and the borrowings or other extensions of credit to be made
on the Closing Date under or pursuant to the Loan Documents and the Financing Documents which
constitutes an Event of Default or Potential Default. None of the Loan Parties or any Subsidiaries
of any Loan Party is in violation of (i) any term of its

57

 

Organizational Documents or (ii) any material agreement or instrument to which it is a party
or by which it or any of its properties may be subject or bound where such violation would, either
alone or together with all other such violations, constitute or be reasonably likely to constitute
a Material Adverse Change. No default or event of default or basis for acceleration exists or,
after giving effect to the borrowing or other extensions of credit made pursuant hereto, will exist
under any instrument or agreement evidencing, providing for the issuance or securing of or
otherwise relating to any Indebtedness of the Borrower or of any other Loan Party.

          6.1.15 Patents, Trademarks, Copyrights, Licenses, Etc.

               Each Loan Party and each Subsidiary of each Loan Party owns or possesses all material patents,
trademarks, service marks, trade names, copyrights, proprietary software, licenses, registrations,
franchises, permits, authorizations of Official Bodies and rights necessary to own and operate its
properties and to carry on its business as presently conducted and planned to be conducted by such
Loan Party or Subsidiary, without known possible, alleged or actual conflict with the rights of
others. All material patents, trademarks, service marks, trade names, copyrights, proprietary
software, licenses, registrations and franchises of each Loan Party and each Subsidiary of each
Loan Party are listed and described on Schedule 6.1.15. To the best knowledge of each Loan
Party, there is no material violation by any Person of any right of any loan Party with respect to
any patent, copyright, proprietary software, service mark, trademark, trade name or other right
owned or used by any Loan Party.

          6.1.16 Security Interests.

               Upon (i) the due and proper filing of financing statements relating to the security interests
referred to below in each office and in each jurisdiction where required in order to perfect such
security interests, (ii) the taking possession by the Collateral Agent of any stock certificates or
other certificates evidencing the Pledged Collateral and (iii) recordation of the Patent, Trademark
and Copyright Security Agreement in the United States Patent and Trademark Office and the United
States Copyright Office, as applicable, the Liens and security interests granted to the Collateral
Agent for the benefit of the Banks pursuant to the Security Documents will constitute Prior
Security Interests under the Uniform Commercial Code as in effect in each applicable jurisdiction
(the “Uniform Commercial Code”) to the extent such Liens and security interests can be perfected by
such filings or possession entitled to all the rights, benefits and priorities provided by the
Uniform Commercial Code except for the Prior Security Interest granted by the Loan Parties in their
assets other than Accounts and Inventory in favor of the Purchasers and except for other Permitted
Liens of the types described in clauses (i), (ii), (iii), (v), (vi) and (ix) of the definition of
that term. There will be upon execution and delivery of the Security Documents, such filings and
such taking of possession, no necessity for any further action in order to preserve, protect and
continue such rights, except the filing of continuation statements with respect to such financing
statements within six months prior to each five-year anniversary of the filing of such financing
statements. All filing fees and other expenses in connection with each such action have been or
will be paid by the Borrower.

          6.1.17 Mortgage Liens.

               The Liens granted to the Collateral Agent for the benefit of the Banks pursuant to each
Mortgage will constitute, upon due and proper recordation of such Mortgage, a valid first priority
Lien, subject only to the Lien in favor of the Purchasers securing obligations

58

 

under the Note Purchase Agreement and Permitted Liens of the types described in clauses (i),
(ii), (iii), (v), (vi) and (ix) of the definition of that term under applicable law, but only to
the extent that applicable law permits a mortgage lien to attach thereto the right, title and
interest of the Loan Party party to such Mortgage in and to the real property described therein.
All such action as will be necessary or advisable to establish such Liens of the Collateral Agent
and the priority thereof as described in the preceding sentence will be taken at or prior to the
time required for such purpose, and there will be as of the date of execution and delivery of the
Mortgages no necessity for any further action in order to protect, preserve and continue such Lien
and such priority.

          6.1.18 Status of the Pledged Collateral.

               All the Subsidiary Ownership Interests and LLC Interests included in the Pledged Collateral to
be pledged pursuant to the Pledge Agreement are validly issued and nonassessable and owned
beneficially and of record by the pledgor free and clear of any Lien or restriction on transfer,
except for Permitted Liens of the types described in clauses (i) and (vi) of the definition of that
term or as otherwise provided by the Pledge Agreement and except as the right of the Collateral
Agent to dispose of the Subsidiary Ownership Interests or LLC Interests may be limited by the
Securities Act and the regulations promulgated by the Securities and Exchange Commission thereunder
and by applicable state securities laws. There are no shareholder, partnership, limited liability
company or other agreements or understandings with respect to the Subsidiary Ownership Interests or
LLC Interests included in the Pledged Collateral except for the partnership agreements and limited
liability company agreements described on Schedule 6.1.18. The Parent and the Loan Parties
have delivered true and correct copies of such partnership agreements and limited liability company
agreements to the Agent and each Bank.

          6.1.19 Insurance.

               Schedule 6.1.19 lists all insurance policies and other bonds to which any Loan Party
or Subsidiary of any Loan Party is a party, all of which are valid and in full force and effect.
No notice has been given or claim made and no grounds exist to cancel or avoid any of such policies
or bonds or to reduce the coverage provided thereby. Such policies and bonds provide adequate
coverage from reputable and financially sound insurers in amounts sufficient to insure the assets
and risks of each Loan Party and each Subsidiary of each Loan Party in accordance with prudent
business practice in the industry of the Loan Parties and their Subsidiaries.

          6.1.20 Compliance with Laws.

               The Loan Parties and their Subsidiaries are in compliance in all material respects with all
applicable Laws (other than Environmental Laws which are specifically addressed in
Section 6.1.26 [Environmental Matters]) in all jurisdictions in which any Loan Party or
Subsidiary of any Loan Party is presently or will be doing business except where the failure to do
so would not, either alone or together with all other such failures, constitute or be reasonably
likely to result in a Material Adverse Change.

          6.1.21 Material Contracts; Burdensome Restrictions.

59

 

               Schedule 6.1.21 lists all material contracts relating to the business operations of
each Loan Party and each Subsidiary of any Loan Party, including, without limitation, all Coal
Supply Contracts, and all employee benefit plans and Labor Contracts. Except as set forth on
Schedule 6.1.21, all such material contracts are valid, binding and enforceable upon such
Loan Party or Subsidiary and each of the other parties thereto in accordance with their respective
terms, and there is no default thereunder on the part of any Loan Party or Subsidiary of any Loan
Party thereto, or to the Loan Parties’ knowledge, on the part of any other party thereto. None of
the Loan Parties or their Subsidiaries is bound by any contractual obligation, or subject to any
restriction in any organization document, or any requirement of Law, which could, either alone or
together with all other such obligations, restriction and requirements, could reasonably be
expected to result in a Material Adverse Change.

          6.1.22 Investment Companies; Regulated Entities.

               None of the Loan Parties or any Subsidiaries of any Loan Party is an “investment company”
registered or required to be registered under the Investment Company Act of 1940 or under the
“control” of an “investment company” as such terms are defined in the Investment Company Act of
1940 and shall not become such an “investment company” or under such “control.” None of the Loan
Parties or any Subsidiaries of any Loan Party is subject to any other federal or state statute or
regulation limiting its ability to incur Indebtedness for borrowed money.

          6.1.23 Intentionally Omitted.

          6.1.24 Plans and Benefit Arrangements.

Change). Neither the Borrower nor any other member of the ERISA Group has been notified by any

in full of the Loans, Reimbursement Obligations and Letter of Credit Borrowings, and interest
thereon, expiration or termination of all Letters of Credit, satisfaction of all of the Loan
Parties’ other Obligations under the Loan Documents and termination of the Commitments, the Loan
Parties shall comply at all times with the following affirmative covenants:

          8.1.1 Preservation of Existence, Etc.

               Each Loan Party shall, and shall cause each of its Subsidiaries to, maintain its legal
existence as a corporation, limited partnership or limited liability company, as the case may be,
and its license or qualification and good standing in each jurisdiction in which its ownership or
lease of property or the nature of its business makes such license or qualification necessary,
except as otherwise expressly permitted in Section 8.2.6 [Liquidations, Mergers, Etc.] or where a
Loan Party shall be in breach of this Section inadvertently because it failed to obtain or maintain
a qualification or license provided that such failure is promptly remedied upon the Loan Party
becoming aware of such failure and the failure does not adversely affect the rights of the Loan
Parties or, either alone or together with all such failures, constitute or be reasonably likely to
result in a Material Adverse Change.

          8.1.2 Payment of Liabilities, Taxes, Etc.

               Each Loan Party shall, and shall cause each of its Subsidiaries to, duly pay and discharge all
liabilities to which it is subject or which are asserted against it, promptly as and when the same
shall become due and payable, including all taxes, assessments and governmental charges upon it or
any of its properties, assets, income or profits, prior to the date on which penalties attach
thereto, except to the extent that such liabilities, including taxes, assessments or charges, are
being contested in good faith and by appropriate and lawful proceedings diligently conducted and
for which such reserve or other appropriate provisions, if any, as shall be required by GAAP shall
have been made, but only to the extent that failure to discharge any such liabilities shall not
result in any additional liability which would adversely affect to a material extent the financial
condition of any Loan Party or Subsidiary of any Loan Party or affect a material portion of the
Collateral, provided that the Loan Parties and their Subsidiaries will pay all such liabilities
forthwith upon the commencement of proceedings to foreclose any Lien which may have attached as
security therefor.

          8.1.3 Maintenance of Insurance.

               Each Loan Party shall, and shall cause each of its Subsidiaries to, insure its properties and
assets against loss or damage by fire and such other insurable hazards against which such assets
are commonly insured (including fire, extended coverage, property damage, workers’ compensation,
public liability and business interruption insurance) and against other risks, and in such amounts,
as similar properties and assets are insured by prudent companies in similar circumstances carrying
on similar businesses, and with reputable and financially sound insurers, including self-insurance
to the extent customary, all as shall be reasonably satisfactory to the Agent. For policies which
cover insured entities in addition to the Borrower and the other

74

 

Loan Parties, the policies shall provide that the required limits per occurrence will continue
to be in effect for the Borrower and the other Loan Parties notwithstanding losses which may occur
with respect to such other Persons. The Loan Parties shall deliver to the Agent (x) on the Closing
Date and annually thereafter an original certificate of insurance signed by the Loan Parties’
independent insurance broker describing and certifying as to the existence of all insurance on the
Collateral required to be maintained by this Agreement and the other Loan Documents, including
business interruption insurance in an amount of $50,000,000 or more in the aggregate among all Loan
Parties, together with a copy of the endorsements described in the next sentence attached to such
certificate and (y) at the request of the Agent, from time to time a summary schedule indicating
all insurance then in force with respect to each of the Loan Parties. Such policies of insurance
shall contain special endorsements, in form and substance reasonably acceptable to the Agent, which
shall (i) specify the Agent as an additional insured, mortgagee and lender loss payee as its
interests may appear, with the understanding that any obligation imposed upon the insured
(including the liability to pay premiums) shall be the sole obligation of the applicable Loan
Parties and not that of the insured, (ii) provide that the interest of the Banks shall be insured
regardless of any breach or violation by the applicable Loan Parties of any warranties,
declarations or conditions contained in such policies or any action or inaction of the applicable
Loan Parties or others insured under such policies, (iii) provide a waiver of any right of the
insurers to set off or counterclaim or any other deduction, whether by attachment or otherwise,
(iv) provide that any and all rights of subrogation which the insurers may have or acquire shall
be, at all times and in all respects, junior and subordinate to the prior payment in full of the
Indebtedness hereunder, including the Indebtedness evidenced by the Notes, and that no insurer
shall exercise or assert any right of subrogation until such time as the Indebtedness hereunder has
been paid in full, (v) include effective waivers by the insurer of all claims for insurance
premiums against the Agent, (vi) provide that no cancellation of such policies for any reason
(other than non-payment of premium) nor any change therein shall be effective until at least
thirty (30) days after receipt by the Agent of written notice of such cancellation or change, and
that no cancellation of such policies for nonpayment of premium shall be effective until at least
ten (10) days after receipt by the Collateral Agent of written notice of such cancellation,
(vii) be primary without right of contribution of any other insurance carried by or on behalf of
any additional insureds with respect to their respective interests in the Collateral, and
(viii) provide that inasmuch as the policy covers more than one insured, all terms, conditions,
insuring agreements and endorsements (except limits of liability) shall operate as if there were a
separate policy covering each insured. The contingent business interruption insurance required
hereunder shall include without limitation coverage in respect of outages at power plants serviced
under any material Coal Supply Contract, so long as such outage is the result of an insured event.
The applicable Loan Parties shall notify the Agent and each Bank promptly of any occurrence causing
a material loss or decline in value of the Collateral and the estimated (or actual, if available)
amount of such loss or decline. With respect to any casualty or property insurance for damage or
destruction of any Collateral, such losses may be adjusted by and be payable to the Loan Parties if
no Event of Default shall have occurred and be continuing and either (i) the Loan Parties promptly
certify in writing to the Agent and Bank that the proceeds shall be used for the repair,
restoration and/or replacement of property in respect of which such proceeds were received and
continue such course of action or (ii) the amount of the proceeds from the losses is $500,000 or
less. Any and all proceeds for losses not addressed in the preceding sentence shall be, at the
option of the Agent, and upon notice thereof to the Borrower, adjusted by and payable to the Agent.
Any monies received by the Agent in accordance with the preceding sentence constituting insurance
proceeds or condemnation proceeds (pursuant to any

75

 

of the Mortgages) may, at the option of the Agent, (i) be applied to the pro rata payment of
the Notes, or (ii) be disbursed to the applicable Loan Parties on such terms as are deemed
appropriate by the Agent for the repair, restoration and/or replacement of property in respect of
which such proceeds were received

          8.1.4 Maintenance of Properties and Leases.

               Each Loan Party shall, and shall cause each of its Subsidiaries to, maintain in good repair,
working order and condition (ordinary wear and tear excepted) in accordance with the general
practice of other businesses of similar character and size, all of those properties useful or
necessary to its business, and from time to time, such Loan Party will make or cause to be made all
appropriate repairs, renewals or replacements thereof.

          8.1.5 Maintenance of Patents, Trademarks, Etc.

               Each Loan Party shall, and shall cause each of its Subsidiaries to, maintain in full force and
effect all patents, trademarks, service marks, trade names, copyrights, licenses, franchises,
permits and other authorizations necessary for the ownership and operation of its properties and
business if the failure so to maintain the same would constitute or be reasonably likely to result
in a Material Adverse Change.

          8.1.6 Visitation Rights.

     The Loan Parties shall permit the representatives of each of the Banks:

               No Default — if no Potential Default or Event of Default then exists, at the expense of such

Borrower or any Subsidiaries, to discuss the affairs, finances and accounts of the Borrower and its
Subsidiaries with the Borrower’s officers, and (with the consent of the Borrower, which consent
will not be unreasonably withheld) its independent public accountants, and (with the consent of the
Borrower, which consent will not be unreasonably withheld) to visit the other offices and
properties of the Borrower and each Subsidiary, all at such reasonable times (which shall be normal
business hours) and as often as may be reasonably requested; and

               Default — if a Potential Default or Event of Default then exists, at the expense of the
Borrower to visit and inspect any of the offices or properties (including, without limitation, any
field examination of Accounts and Inventory) of the Borrower or any Subsidiary, to examine all
their respective books of account, records, reports and other papers, to make copies and extracts
therefrom, and to discuss their respective affairs, finances and accounts with their respective
officers and independent public accountants (and by this provision the Borrower authorizes said
accountants to discuss the affairs, finances and accounts of the Borrower and its Subsidiaries),
all at such times and as often as may be requested.

76

 

approvals as are necessary for conducting uninterrupted coal mining and related operations on,
in or under the Real Property or such other property, sufficient to discharge in all material
respects the obligations of the Loan Parties under the Coal Supply Contracts, substantially in the
manner as such operations have heretofore been authorized and conducted on those portions of the
Real Property or such other property on which any of the Loan Parties or any of their Subsidiaries
have previously engaged in mining.

          8.1.8 Keeping of Records and Books of Account.

               The Borrower shall, and shall cause each Subsidiary of the Borrower to, maintain and keep
proper books of record and account which enable the Borrower and its Subsidiaries to issue
financial statements in accordance with GAAP and as otherwise required by applicable Laws of any
Official Body having jurisdiction over the Borrower or any Subsidiary of the Borrower, and in which
full, true and correct entries shall be made in all material respects of all its dealings and
business and financial affairs.

          8.1.9 Plans and Benefit Arrangements.

               After the Closing Date, the Borrower shall, and shall cause each other member of the ERISA
Group to, comply with ERISA, the Internal Revenue Code and other applicable Laws applicable to
Plans and Benefit Arrangements except where the failure to comply herewith, alone or together with
all other such failures, would not result in any substantial obligation to the Borrower or any of
its Subsidiaries or otherwise result in a Material Adverse Change. Without limiting the generality
of the foregoing, the Borrower shall cause all of its Plans and all Plans maintained by any member
of the ERISA Group to be funded in accordance with at least the minimum funding requirements of
ERISA and to be and remain Adequately Funded, and shall make, and cause each member of the ERISA

result in a Material Adverse Change, including without limitation, if such failure to comply would

described in paragraphs (i) through (v) of the definition of the term “Permitted Investments”,
(valued as provided in the Collateral Agency Agreement) in amounts sufficient to assure that the
aggregate amount credited thereto (inclusive of the undrawn face amount of any Debt Service Letter
of Credit then held by the Note Purchase Collateral Agent for credit to the Debt Service Reserve
Account) shall at all times be at least equal to the Debt Service Reserve Requirement as the same
may change from time to time. For purposes hereof, the “Debt Service Reserve Requirement” shall

six months next following such Payment Date;

from Moody’s or ‘A’ or better from S&P (an “Eligible Issuer”) for the account of a Person (which
may be Parent or another member of the Parent Group) other than the Borrower or any of its
Subsidiaries (it being understood that neither the Borrower nor any of its Subsidiaries shall be an
account party or be or become directly or indirectly liable to the issuer thereof for any
reimbursement obligation in respect of any Debt Service Reserve Letter of Credit); (x) be in a face
amount equal to that portion of the amount of cash and Permitted Investments required to be

81

 

maintained in the Debt Service Account for which it is to be substituted; (y) have a term of
at least 364 days; and (z) be subject to a drawing in full by the Note Purchase Collateral Agent
(1) if, at least ninety days prior to its stated expiration, it is not replaced with a further Debt
Service Letter of Credit delivered to the Note Purchase Collateral Agent in a face amount, or by
cash or Permitted Investments deposited to the credit of the Debt Service Reserve Account in an
aggregate amount, sufficient to assure that the aggregate amount deposited in or credited to the
Debt Service Reserve Account shall be at least equal to the Debt Service Reserve Requirement as at
the time of such replacement, (2) upon the occurrence of an Event of Default, and (3) if on any
date the Note Purchase Collateral Agent receives notice from the Borrower or any holder of the Term
Notes that the issuer of such Debt Service Letter of Credit is not or has ceased to be an Eligible
Issuer.

          The proceeds from any drawing under a Debt Service Letter of Credit shall be deposited into
the Debt Service Reserve Account and be held and applied by the Note Purchase Collateral Agent in
accordance with the applicable provisions of the Note Purchase Agreement and the Note Purchase
Collateral Agency Agreement. Upon the written request of the Borrower furnished to the Note
Purchase Collateral Agent (with a copy to the Agent), the Note Purchase Collateral Agent shall
return any Debt Service Letter of Credit to the named account party thereof if, after giving effect
to such return, (x) the cash and Permitted Investments remaining on deposit to the credit of the
Debt Service Reserve Account would be at least equal to the Debt Service Reserve Requirement and
(y) no Event of Default shall have occurred and be continuing, and (z) such request shall be
accompanied by an Officer’s Certificate to the effects set forth in clauses (x) and (y) of this
sentence (upon which Officer’s Certificate the Note Purchase Collateral Agent shall be conclusively
entitled to rely). Amounts, if any, credited to the Debt Service Reserve Account in excess of the
Debt Service Reserve Requirement applicable from time to time may be withdrawn therefrom upon the
request of the Borrower in the manner and subject to the conditions specified in Section 3.5 of the
Note Purchase Collateral Agency Agreement.

Expenditures, and other purposes incident to the conduct of such business; provided, however, that
Retained Cash shall not in any event be applied to the making of distributions or dividends to
Parent or any other member of the Parent Group or to pay Management Fees to the Parent.

          8.1.20 Subordination of Management Fees; Payment of Management Fees.

          The Borrower shall cause any fees or charges, of whatever nature, payable by the Loan Parties
to any member of the Parent Group, including without limitation, the Non-Cash Income Tax Expense
and all fees and charges in connection with the management of the operations of the Borrower, to be
subordinated to the payment of the Notes and other Obligations, with the subordination in the case
of payments to the Parent to be pursuant to the Management Fee Subordination Agreement and the
subordination in the case of payments to any other Affiliate of the Borrower to be on terms
satisfactory to, and set forth in writing approved by, the Required Banks. The Loan Parties agree
that the payment of any fees or charges to the

82

 

Parent or any other member of the Parent Group, all of which are subordinated in accordance
with the preceding sentence, may be made by the Loan Parties only if such payments are in
accordance with the following: (i) prior to and after giving effect to the payment thereof, no
Event of Default or Potential Default is in existence; (ii) the payments consist solely of the
Management Fee, plus Third Party Services Payments; and (iii) such payments shall be otherwise
permitted by and in accordance with the Management Fee Subordination Agreement; provided that,
notwithstanding anything contained in this Subsection or the Management Fee Subordination Agreement
to the contrary, in the event that the Borrower is permitted to make a dividend or distribution in
accordance with Section 8.2.5 [Dividends and Related Distributions], the Borrower shall be
permitted, in lieu of making such permitted distribution or dividend, to apply the amount available
for such permitted dividend or distribution to reduce the payable arising from the Non-Cash Income
Tax Expense.

other Guarantor or any of their Subsidiaries (other than TWCC) as to which the Agent, for the

          8.1.23 Payment of Indebtedness.

          The Borrower will (i) pay or cause to be paid the principal of and interest on all
Indebtedness at any time incurred or assumed by it when and as the same shall become due and

purchase, redemption, retirement or acquisition of its shares of capital stock, partnership
interests or limited liability company interests (or warrants, options or rights therefor) or make
any Management Fee payment, except that:

               (i) so long as (A) no Potential Default or Event of Default is in existence or would result
therefrom and (B) the amount at the time credited to the Debt Service Reserve Account shall be at
least equal to the Debt Service Reserve Requirement at such time the Borrower may (1) on the
Closing Date, make a distribution of $8,500,000 to Parent from the proceeds of the sale of the Term

such Payment Date (including accrued Management Fee payments, if any, for prior fiscal quarterly
periods which remain unpaid), in an amount not exceeding, in the aggregate for such distribution
and Management Fee payment (including accrued Management Fee payments for prior periods), Excess
Cash Flow as of such Payment Date; provided, that the amount of Excess Cash Flow as of each Payment
Date, and the amount so distributable pursuant to this sub-clause (2) on the basis of the
computation of such Excess Cash Flow, shall be subject to adjustment pursuant to Section 8.2.5(b);
and

               (ii) any Subsidiary of the Borrower may make dividends and distributions to the Borrower or to
any other Subsidiary in respect of Equity Interests of such Subsidiary owned by the Borrower or
such other Subsidiary, as the case may be.

The Borrower shall not and shall not permit any of its Subsidiaries to enter into any contract or
agreement which restricts in any manner the payment by any Subsidiary of the Borrower of dividends
or distributions to the Borrower or any other Subsidiary which shall own Equity Interests of such
Subsidiary; provided, however, that the Borrower and TWCC may enter into the NRGT Documents,
notwithstanding the potential restrictive effects thereof on the payment of dividends and
distributions by TWCC.

                    (b) The distributions and Management Fee payments made by the Borrower to the Parent pursuant
to sub-clause (i)(2) of Section 8.2.5(a) from Excess Cash Flow as of each Payment Date in any
fiscal year shall be subject to adjustment in accordance with the further provisions of this
Section 8.2.5(b). Following the completion of each fiscal year of the Borrower, the amount of
Excess Cash Flow as of each Payment Date in such fiscal year shall be recalculated based upon the
annual audited financial statements of the Loan Parties for such fiscal year. For this purpose,
Available Cash and Excess Cash Flow as of

87

 

each such Payment Date shall be recomputed in accordance with the definitions of “Available
Cash” and “Excess Cash Flow” set forth in Schedule B of the Note Purchase Agreement, in each case
using the actual numbers for the applicable quarterly period derived from such audited financial
statements. Based on such recomputations, as promptly as practicable, but in any event not later
than contemporaneously with the Borrower’s delivery to the Banks of its audited financial
statements for such fiscal year pursuant to Section 8.3.3 [Annual Financial Statements], the
Borrower shall furnish to each such holder an Officer’s Certificate (which may be combined with the
Officer’s Certificate required to be delivered for such fiscal year pursuant to Section 8.3.4
[Certificate of the Borrower]), (i) showing all such recomputations in respect of each fiscal
quarter in such fiscal year and demonstrating the manner in which the same were made, and (ii)
setting forth the amount of each adjustment required in accordance with this Section 8.2.5(b) by
reason of such recomputations in the amount of any distribution or Management Fee payment made in
such fiscal year. All such adjustments based on audited financial information shall be made as
follows:

               (i) in the event that the audited financial information demonstrates that Parent received
monies in excess of that which it should have received for such annual fiscal period, the Borrower
shall cause an amount equal to such excess monies to be paid by Parent to the Borrower; provided,
however, that if Parent shall not have paid the amount of any such excess monies to the Borrower in
full, the amount of such excess monies (or the portion thereof not so paid) shall be deducted from
the amounts which would otherwise be available for distribution to Parent pursuant to this Section
8.2.5 in succeeding fiscal quarters until the full amount of such unpaid excess monies shall have
been so deducted; and

               (ii) in the event that the audited financial information demonstrates that the Borrower should
have been permitted to make distributions or Management Fee payments exceeding the amounts thereof
actually distributed and paid in such fiscal year (the amount of any such excess, the “Underpaid
Amount”), then so long as (x) no Potential Default or Event of Default is in existence or would
result therefrom and (y) the amount at the time credited to the Debt Service Reserve Account shall
be at least equal to the Debt Service Reserve Requirement at such time, the Borrower may make a
further distribution to Parent and/or make a payment in respect of Management Fees, in an amount
not exceeding, in the aggregate for such further distribution and payment in respect of Management
Fees, the Underpaid Amount.

All recomputations and adjustments pursuant to this Section 8.2.5(b) in respect of any fiscal year
shall be made within ten Business Days of the Borrower’s delivery to the Banks of the audited
financial statements for such fiscal year.

          8.2.6 Liquidations, Mergers, Consolidations, Acquisitions.

               Each of the Loan Parties shall not, and shall not permit any of its Subsidiaries to, dissolve,
liquidate or wind-up its affairs, or become a party to any merger or consolidation, or acquire by
purchase, lease or otherwise all or substantially all of the assets or capital stock of any other
Person without the prior written consent of the Agent, provided that any Loan Party may consolidate
or merge with any other Person or convey, transfer or lease all or substantially all of its assets
in a single transaction or a series of transactions to any Person if:

                    (a) the successor formed by such consolidation or the survivor of such merger or the Person
that acquires by conveyance, transfer or lease all or

88

 

substantially all of the assets of such Loan Party as an entirety, as the case may be, shall
be a solvent corporation or limited liability company organized and existing under the laws of the
United States or any State thereof (including the District of Columbia), and, if such Loan Party is
not such a corporation or limited liability company, (i) such corporation or limited liability
company shall have executed and delivered to Agent, an agreement, reasonably satisfactory in form
and substance to the Agent, providing for its assumption of the due and punctual performance and

the date as of which made;

contained in Section 8.1.6 [Visitation Rights] or Section 8.2 [Negative Covenants] or shall fail to
comply with the covenants contained in Section 8.1.16 [Single Purpose Entity]; provided, that, with
respect to the covenants contained in Section 8.1.16, such violation or failure to comply shall not
constitute an Event of Default so long as (A) such violation or failure to comply was immaterial to
the covenants contained in Section 8.1.16 taken as a whole, and (B) if such violation or failure to
comply is curable, the Loan Parties shall cure such violation or failure to comply within thirty

Borrower or any Subsidiary of the Borrower is in default in the performance of or compliance with
any term of any evidence of any Indebtedness in an aggregate outstanding principal amount of at
least $500,000 or of any mortgage, indenture or other agreement relating thereto or any other
condition exists, and as a consequence of such default or condition such Indebtedness described in
clauses (ii) and (iii) has been declared due and payable (or one or more Persons are entitled to

under the other Note Purchase Documents; or

          9.1.7 Events Relating to Plans and Benefit Arrangements.

Security Document or the Intercreditor Agreement.

     9.2 Consequences of Event of Default.

          9.2.1 Events of Default Other Than Bankruptcy, Insolvency or Reorganization
Proceedings.

               If an Event of Default specified under Sections 9.1.1 [Payments Under Loan Documents] through
9.1.8 [Change of Control] shall occur and be continuing, the Banks and the Agent shall be under no
further obligation to make Loans or issue Letters of Credit, as the case may be, and the Agent may,
and upon the request of the Required Banks, shall (i) by written notice to the Borrower, declare
the unpaid principal amount of the Notes then outstanding and all interest accrued thereon, any
unpaid fees and all other Indebtedness of the Borrower to the Banks hereunder and thereunder to be
forthwith due and payable, and the same shall thereupon become and be immediately due and payable
to the Agent for the benefit of each Bank without presentment, demand, protest or any other notice
of any kind, all of which are hereby expressly waived, and (ii) require the Borrower to, and the
Borrower shall thereupon, deposit in a non-interest-bearing account with the Agent, as cash
Collateral for its Obligations under the Loan Documents, an amount equal to the maximum amount
currently or at any time thereafter available to be drawn on all outstanding Letters of Credit, and
the Borrower hereby pledges to the Agent and the Banks, and grants to the Agent and the Banks a
security interest in, all such cash as security for such Obligations. Upon the curing of all
existing Events of Default to the satisfaction of the Required Banks, the Agent shall return such
cash Collateral to the Borrower; and

          9.2.2 Bankruptcy, Insolvency or Reorganization Proceedings.

               If an Event of Default specified under Section 9.1.9 [Involuntary Proceedings] or 9.1.10
[Voluntary Proceedings] shall occur, the Banks shall be under no further obligations to make Loans
hereunder and the unpaid principal amount of the Loans then outstanding and all interest accrued
thereon, any unpaid fees and all other Indebtedness of the Borrower to the Banks hereunder and
thereunder shall be immediately due and payable, without presentment, demand, protest or notice of
any kind, all of which are hereby expressly waived; and

          9.2.3 Set-off.

               If an Event of Default shall occur and be continuing, any Bank to whom any Obligation is owed
by any Loan Party hereunder or under any other Loan Document or any participant of such Bank which
has agreed in writing to be bound by the provisions of Section 10.13 [Equalization of Banks] and
any branch, Subsidiary or Affiliate of such Bank or participant anywhere in the world shall have
the right, in addition to all other rights and remedies available to it, without notice to such
Loan Party, to set-off against and apply to the then unpaid balance of all the Loans and all other
Obligations of the Borrower and the other Loan Parties hereunder or under any other Loan Document
any debt owing to, and any other funds held in any manner for the account of, the Borrower or such
other Loan Party (other than TWCC) by such
Bank or participant or by such branch, Subsidiary or Affiliate, including all funds in all
deposit accounts (whether time or demand, general or special, provisionally credited or finally
credited,

102

 

or otherwise) now or hereafter maintained by the Borrower or such other Loan Party (other
than TWCC) for its own account (but not including funds held in custodian or trust accounts) with
such Bank or participant or such branch, Subsidiary or Affiliate. Such right shall exist whether
or not any Bank or the Agent shall have made any demand under this Agreement or any other Loan
Document, whether or not such debt owing to or funds held for the account of the Borrower or such
other Loan Party (other than TWCC) is or are matured or unmatured and regardless of the existence
or adequacy of any Collateral, Guaranty or any other security, right or remedy available to any
Bank or the Agent. Notwithstanding anything contained in this Section 9.2.3 to the contrary, to
the extent that Borrower maintains a deposit account with any Bank, which Borrower has identified
to the Agent as containing monies solely for the payment of black lung trust fund obligations (the
“Black Lung Trust Account”), the Banks agree that they will not set-off against any monies
contained in such Black Lung Trust Account; and

          9.2.4 Suits, Actions, Proceedings.

               If an Event of Default shall occur and be continuing, and whether or not the Agent shall have
accelerated the maturity of Loans pursuant to any of the foregoing provisions of this Section 9.2,
the Agent or any Bank, if owed any amount with respect to the Loans, may proceed to protect and
enforce its rights by suit in equity, action at law and/or other appropriate proceeding, whether
for the specific performance of any covenant or agreement contained in this Agreement or the other
Loan Documents, including as permitted by applicable Law the obtaining of the ex parte appointment
of a receiver, and, if such amount shall have become due, by declaration or otherwise, proceed to
enforce the payment thereof or any other legal or equitable right of the Agent or such Bank; and

          9.2.5 Application of Proceeds.

               From and after the date on which the Agent has taken any action pursuant to this Section 9.2
and until all Obligations of the Borrower and the Guarantors have been paid in full, any and all
proceeds received by the Agent from any sale or other disposition of the Collateral, or any part
thereof, or the exercise of any other remedy by the Agent, shall be applied as follows:

          (i) first, to reimburse the Agent and the Banks for out-of-pocket costs, expenses and
disbursements, including reasonable attorneys’ and paralegals’ fees and legal expenses, incurred by
the Agent or the Banks in connection with realizing on the Collateral or collection of any
Obligations of any of the Loan Parties under any of the Loan Documents, including advances made by
the Banks or any one of them or the Agent for the reasonable maintenance, preservation, protection
or enforcement of, or realization upon, the Collateral, including advances for taxes, insurance,
repairs and the like and reasonable expenses incurred to sell or otherwise realize on, or prepare
for sale or other realization on, any of the Collateral;

          (ii) second, to the repayment of all Indebtedness then due and unpaid of the Loan Parties to
the Banks incurred under this Agreement or any of the other Loan Documents, whether of principal,
interest, fees, expenses or otherwise, in such manner as the Agent may determine in its discretion;
and

          (iii) the balance, if any, as required by Law.

103

 

          9.2.6 Other Rights and Remedies.

               In addition to all of the rights and remedies contained in this Agreement or in any of the
other Loan Documents (including the Mortgage), the Agent shall have all of the rights and remedies
of a secured party under the Uniform Commercial Code or other applicable Law, all of which rights
and remedies shall be cumulative and non-exclusive, to the extent permitted by Law. The Agent may,
and upon the request of the Required Banks shall, exercise all post-default rights granted to the
Agent and the Banks under the Loan Documents or applicable Law.

     9.3 Notice of Sale.

          Any notice required to be given by the Agent of a sale, lease, or other disposition of the
Collateral or any other intended action by the Agent, if given ten (10) days prior to such proposed
action, shall constitute commercially reasonable and fair notice thereof to the Borrower.

10. THE AGENT

     10.1 Appointment.

          Each Bank hereby irrevocably designates, appoints and authorizes PNC Bank to act as Agent for
such Bank under this Agreement and to execute and deliver or accept on behalf of each of the Banks
the other Loan Documents. Each Bank hereby irrevocably authorizes, and each holder of any Note by
the acceptance of a Note shall be deemed irrevocably to authorize, the Agent to take such action on
its behalf under the provisions of this Agreement and the other Loan Documents and any other
instruments and agreements referred to herein, and to exercise such powers and to perform such
duties hereunder as are specifically delegated to or required of the Agent by the terms hereof,
together with such powers as are reasonably incidental thereto. PNC Bank agrees to act as the
Agent on behalf of the Banks to the extent provided in this Agreement.

     10.2 Delegation of Duties.

          The Agent may perform any of its duties hereunder by or through agents or employees (provided
such delegation does not constitute a relinquishment of its duties as Agent) and, subject to
Sections 10.5 [Reimbursement of Agent by Borrower, Etc.] and 10.6, shall be entitled to engage and
pay for the advice or services of any attorneys, accountants or other experts concerning all
matters pertaining to its duties hereunder and to rely upon any advice so obtained.

     10.3 Nature of Duties; Independent Credit Investigation.

          The Agent shall have no duties or responsibilities except those expressly set forth in this
Agreement and no implied covenants, functions, responsibilities, duties, obligations, or
liabilities shall be read into this Agreement or otherwise exist. The duties of the Agent shall be
mechanical and administrative in nature; the Agent shall not have by reason of this Agreement a
fiduciary or trust relationship in respect of any Bank; and nothing in this Agreement, expressed
or implied, is intended to or shall be so construed as to impose upon the Agent any
obligations in

104

 

respect of this Agreement except as expressly set forth herein. Without limiting
the generality of the foregoing, the use of the term “agent” in this Agreement with reference to
the 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 merely as a matter
of market custom, and is intended to create or reflect only an administrative relationship between
independent contracting parties. Each Bank expressly acknowledges (i) that the Agent has not made
any representations or warranties to it and that no act by the Agent hereafter taken, including any
review of the affairs of any of the Loan Parties, shall be deemed to constitute any representation
or warranty by the Agent to any Bank; (ii) that it has made and will continue to make, without
reliance upon the Agent, its own independent investigation of the financial condition and affairs
and its own appraisal of the creditworthiness of each of the Loan Parties in connection with this
Agreement and the making and continuance of the Loans hereunder; and (iii) except as expressly
provided herein, that the Agent shall have no duty or responsibility, either initially or on a
continuing basis, to provide any Bank with any credit or other information with respect thereto,
whether coming into its possession before the making of any Loan or at any time or times
thereafter.

     10.4 Actions in Discretion of Agent; Instructions From the Banks.

          The Agent agrees, upon the written request of the Required Banks, to take or refrain from
taking any action of the type specified as being within the Agent’s rights, powers or discretion
herein, provided that the Agent shall not be required to take any action which exposes the Agent to
personal liability or which is contrary to this Agreement or any other Loan Document or applicable
Law. In the absence of a request by the Required Banks, the Agent shall have authority, in its
sole discretion, to take or not to take any such action, unless this Agreement specifically
requires the consent of the Required Banks or all of the Banks. Any action taken or failure to act
pursuant to such instructions or discretion shall be binding on the Banks, subject to Section 10.6
[Exculpatory Provisions, Etc.]. Subject to the provisions of Section 10.6 [Exculpatory
Provisions], no Bank shall have any right of action whatsoever against the Agent as a result of the
Agent acting or refraining from acting hereunder in accordance with the instructions of the
Required Banks, or in the absence of such instructions, in the absolute discretion of the Agent.

     10.5 Reimbursement and Indemnification of Agent by the Borrower.

          The Borrower shall indemnify the Agent (and any sub-agent thereof), each Bank and the Issuing
Bank, and each Related Party of any of the foregoing Persons (each such Person being called an
“Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses (including the fees, charges and disbursements of any
counsel for any Indemnitee), and shall indemnify and hold harmless each Indemnitee from all fees
and time charges and disbursements for attorneys who may be employees of any Indemnitee, incurred
by any Indemnitee or asserted against any Indemnitee by any third party or by the Borrower or any
other Loan Party arising out of, in connection with, or as a result of (i) the execution or
delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated
hereby or thereby, the performance by the parties hereto of their respective obligations hereunder
or thereunder or the consummation of the transactions contemplated hereby or thereby, (ii) any Loan
or Letter of Credit or the use or proposed 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

105

 

not strictly comply with the terms of such Letter of Credit), (iii) breach of representations,
warranties or covenants of the Borrower under the Loan Documents, or (iv) any actual or prospective
claim, litigation, investigation or proceeding relating to any of the foregoing, including any such
items or losses relating to or arising under Environmental Laws or pertaining to environmental
matters, whether based on contract, tort or any other theory, whether brought by a third party or
by the Borrower or any other Loan Party, and regardless of whether any Indemnitee is a party
thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the
extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a
court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or willful misconduct of such Indemnitee or (y) result from a claim brought by the
Borrower or any other Loan Party against an Indemnitee for breach in bad faith of such Indemnitee’s
obligations hereunder or under any other Loan Document, if the Borrower or such Loan Party has
obtained a final and nonappealable judgment in its favor on such claim as determined by a court of
competent jurisdiction.

          To the extent that the Borrower for any reason fails to indefeasibly pay any amount required
under Sections 5.6.1 [Costs and Expenses] or this Section 10.5 [Indemnification by the Borrower] to
be paid by it to the Agent (or any sub-agent thereof), the Issuing Bank or any Related Party of any
of the foregoing, each Bank severally agrees to pay to the Agent (or any such sub-agent), the
Issuing Bank or such Related Party, as the case may be, such Bank’s Ratable Share (determined as of
the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid
amount, provided that the unreimbursed expense or indemnified loss, claim, damage,
liability or related expense, as the case may be, was incurred by or asserted against the Agent (or
any such sub-agent) or the Issuing Bank in its capacity as such, or against any Related Party of
any of the foregoing acting for the Agent (or any such sub-agent) or Issuing Bank in connection
with such capacity.

     10.6 Exculpatory Provisions; Limitation of Liability.

          Neither the Agent nor any of its directors, officers, employees, agents, attorneys or
Affiliates shall (a) be liable to any Bank for any action taken or omitted to be taken by it or
them hereunder, or in connection herewith including pursuant to any Loan Document, unless caused by
its or their own gross negligence or willful misconduct, (b) be responsible in any manner to any of
the Banks for the effectiveness, enforceability, genuineness, validity or the due execution of this
Agreement or any other Loan Documents or for any recital, representation, warranty, document,
certificate, report or statement herein or made or furnished under or in connection with this
Agreement or any other Loan Documents, or (c) be under any obligation to any of the Banks to
ascertain or to inquire as to the performance or observance of any of the terms, covenants or
conditions hereof or thereof on the part of the Loan Parties, or the financial condition of the
Loan Parties, or the existence or possible existence of any Event of Default or Potential Default.
No claim may be made by any of the Loan Parties, any Bank, the Agent or any of their respective
Subsidiaries against the Agent, any Bank or any of their respective directors, officers, employees,
agents, attorneys or Affiliates, or any of them, for any special, indirect or consequential damages
or, to the fullest extent permitted by Law, for any punitive damages in respect of any claim or
cause of action (whether based on contract, tort, statutory liability, or any other ground) based
on, arising out of or related to any Loan Document or the transactions contemplated hereby or any
act, omission or event occurring in connection therewith, including the negotiation, documentation, administration or collection of the Loans, and each of the
Loan

106

 

Parties, (for itself and on behalf of each of its Subsidiaries), the Agent and each Bank
hereby waive, releases and agree never to sue upon any claim for any such damages, whether such
claim now exists or hereafter arises and whether or not it is now known or suspected to exist in
its favor. Each Bank agrees that, except for notices, reports and other documents expressly
required to be furnished to the Banks by the Agent hereunder or given to the Agent for the account
of or with copies for the Banks, the Agent and each of its directors, officers, employees, agents,
attorneys or Affiliates shall not have any duty or responsibility to provide any Bank with an
credit or other information concerning the business, operations, property, condition (financial or
otherwise), prospects or creditworthiness of the Loan Parties which may come into the possession of
the Agent or any of its directors, officers, employees, agents, attorneys or Affiliates.

     10.7 Reimbursement and Indemnification of Agent by Banks.

          Each Bank agrees to reimburse and indemnify the Agent (to the extent not reimbursed by the
Borrower and without limiting the Obligation of the Borrower to do so) in proportion to its Ratable
Share from and against all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements, including attorneys’ fees and disbursements
(including the allocated costs of staff counsel), and costs of appraisers and environmental
consultants, of any kind or nature whatsoever which may be imposed on, incurred by or asserted
against the Agent, in its capacity as such, in any way relating to or arising out of this Agreement
or any other Loan Documents or any action taken or omitted by the Agent hereunder or thereunder,
provided that no Bank shall be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements (a) if the
same results from the Agent’s gross negligence or willful misconduct, or (b) if such Bank was not
given notice of the subject claim and the opportunity to participate in the defense thereof, at its
expense (except that such Bank shall remain liable to the extent such failure to give notice does
not result in a loss to the Bank), or (c) if the same results from a compromise and settlement
agreement entered into without the consent of such Bank, which shall not be unreasonably withheld.
In addition, each Bank agrees promptly upon demand to reimburse the Agent (to the extent not
reimbursed by the Borrower and without limiting the Obligation of the Borrower to do so) in
proportion to its Ratable Share for all amounts due and payable by the Borrower to the Agent in
connection with the Agent’s periodic audit of the Loan Parties’ books, records and business
properties.

     10.8 Reliance by Agent.

          The Agent shall be entitled to rely upon any writing, telegram, telex or teletype message,
resolution, notice, consent, certificate, letter, cablegram, statement, order or other document or
conversation by telephone or otherwise believed by it to be genuine and correct and to have been
signed, sent or made by the proper Person or Persons, and upon the advice and opinions of counsel
and other professional advisers selected by the Agent. The Agent shall be fully justified in
failing or refusing to take any action hereunder unless it shall first be indemnified to its
satisfaction by the Banks against any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action.

     10.9 Notice of Default.

107

 

          The Agent shall not be deemed to have knowledge or notice of the occurrence of any Potential
Default or Event of Default unless the Agent has received written notice from a Bank or the
Borrower referring to this Agreement, describing such Potential Default or Event of Default and
stating that such notice is a “notice of default.”

     10.10 Notices.

          The Agent shall promptly send to each Bank a copy of all notices received from the Borrower
pursuant to the provisions of this Agreement or the other Loan Documents promptly upon receipt
thereof. The Agent shall promptly notify the Borrower and the other Banks of each change in the
Base Rate and the effective date thereof.

     10.11 Banks in Their Individual Capacities; Agent in its Individual Capacity.

          With respect to its Revolving Credit Commitment, and the Revolving Credit Loans made by it and
any other rights and powers given to it as a Bank hereunder or under any of the other Loan
Documents, the Agent shall have the same rights and powers hereunder as any other Bank and may
exercise the same as though it were not the Agent, and the term “Bank” and “Banks” shall, unless
the context otherwise indicates, include the Agent in its individual capacity. PNC Bank and its
Affiliates and each of the Banks and their respective Affiliates may, without liability to account,
except as prohibited herein, make loans to, issue letters of credit for the account of, acquire
equity interests in, accept deposits from, discount drafts for, act as trustee under indentures of,
and generally engage in any kind of banking, trust, financial advisory, underwriting or other
business with, the Loan Parties and their Affiliates, in the case of the Agent, as though it were
not acting as Agent hereunder and in the case of each Bank, as though such Bank were not a Bank
hereunder, in each case without notice to or consent of the other Banks. The Banks acknowledge
that, pursuant to such activities, the Agent or its Affiliates may (i) receive information
regarding the Loan Parties or any of their Subsidiaries or Affiliates (including information that
may be subject to confidentiality obligations in favor of the Loan Parties or such Subsidiary or
Affiliate) and acknowledge that the Agent shall be under no obligation to provide such information
to them, and (ii) accept fees and other consideration from the Loan Parties for services in
connection with this Agreement and otherwise without having to account for the same to the Banks.

     10.12 Holders of Notes.

          The Agent may deem and treat any payee of any Note as the owner thereof for all purposes
hereof unless and until written notice of the assignment or transfer thereof shall have been filed
with the Agent. Any request, authority or consent of any Person who at the time of making such
request or giving such authority or consent is the holder of any Note shall be conclusive and
binding on any subsequent holder, transferee or assignee of such Note or of any Note or Notes
issued in exchange therefor.

     10.13 Equalization of Banks.

          The Banks and the holders of any participations in any Notes agree among themselves that, with
respect to all amounts received by any Bank or any such holder for application on any Obligation
hereunder or under any Note or under any such participation, whether received by voluntary payment,
by realization upon security, by the exercise of the right

108

 

of set-off or banker’s lien, by counterclaim or by any other non-pro rata source, equitable
adjustment will be made in the manner stated in the following sentence so that, in effect, all such
excess amounts will be shared ratably among the Banks and such holders in proportion to their
interests in payments under the Notes, except as otherwise provided in Section 4.4.3 [Agent’s and
Bank’s Rights], 5.4.2 [Replacement of a Bank] or 5.6 [Additional Compensation in Certain
Circumstances]. The Banks or any such holder receiving any such amount shall purchase for cash
from each of the other Banks an interest in such Bank’s Loans in such amount as shall result in a
ratable participation by the Banks and each such holder in the aggregate unpaid amount under the
Notes, provided that if all or any portion of such excess amount is thereafter recovered from the
Bank or the holder making such purchase, such purchase shall be rescinded and the purchase price
restored to the extent of such recovery, together with interest or other amounts, if any, required
by law (including court order) to be paid by the Bank or the holder making such purchase.

     10.14 Successor Agent.

          The Agent (i) may resign as Agent or (ii) shall resign if such resignation is requested by the
Required Banks (if the Agent is a Bank, the Agent’s Loans and its Commitment shall be considered in
determining whether the Required Banks have requested such resignation) or required by
Section 5.4.2 [Replacement of a Bank], in either case of (i) or (ii) by giving not less than thirty
(30) days’ prior written notice to the Borrower. If the Agent shall resign under this Agreement,
then either (a) the Required Banks shall appoint from among the Banks a successor agent for the
Banks, subject to the consent of the Borrower, such consent not to be unreasonably withheld, or
(b) if a successor agent shall not be so appointed and approved within the thirty (30) day period
following the Agent’s notice to the Banks of its resignation, then the Agent shall appoint, with
the consent of the Borrower, such consent not to be unreasonably withheld, a successor agent who
shall serve as Agent until such time as the Required Banks appoint and the Borrower consents to the
appointment of a successor agent. Upon its appointment pursuant to either clause (a) or (b) above,
such successor agent shall succeed to the rights, powers and duties of the Agent, and the term
“Agent” shall mean such successor agent, effective upon its appointment, and the former Agent’s
rights, powers and duties as Agent shall be terminated without any other or further act or deed on
the part of such former Agent or any of the parties to this Agreement. After the resignation of
any Agent hereunder, the provisions of this Section 10 shall inure to the benefit of such former
Agent and such former Agent shall not by reason of such resignation be deemed to be released from
liability for any actions taken or not taken by it while it was an Agent under this Agreement.

     10.15 Availability of Funds.

          The Agent may assume that each Bank has made or will make the proceeds of a Loan available to
the Agent unless the Agent shall have been notified by such Bank on or before the later of (1) the
close of Business on the Business Day preceding the Borrowing Date with respect to such Loan or two
(2) hours before the time on which the Agent actually funds the proceeds of such Loan to the
Borrower (whether using its own funds pursuant to this Section 10.15 or using proceeds deposited
with the Agent by the Banks and whether such funding occurs before or after the time on which Banks
are required to deposit the proceeds of such Loan with the Agent). The Agent may, in reliance upon
such assumption (but shall not be required to), make available to the Borrower a corresponding
amount. If such corresponding amount is not in fact made available to the Agent by such Bank, the
Agent shall be entitled to

109

 

recover such amount on demand from such Bank (or, if such Bank fails to pay such amount
forthwith upon such demand from the Borrower) together with interest thereon, in respect of each
day during the period commencing on the date such amount was made available to the Borrower and
ending on the date the Agent recovers such amount, at a rate per annum equal to (i) the Federal
Funds Effective Rate during the first three (3) days after such interest shall begin to accrue and
(ii) the applicable interest rate in respect of such Loan after the end of such three-day period.

     10.16 Calculations.

          In the absence of gross negligence or willful misconduct, the Agent shall not be liable for
any error in computing the amount payable to any Bank whether in respect of the Loans, fees or any
other amounts due to the Banks under this Agreement. In the event an error in computing any amount
payable to any Bank is made, the Agent, the Borrower and each affected Bank shall, forthwith upon
discovery of such error, make such adjustments as shall be required to correct such error, and any
compensation therefor will be calculated at the Federal Funds Effective Rate.

     10.17 Beneficiaries.

          Except as expressly provided herein, the provisions of this Section 10 are solely for the
benefit of the Agent and the Banks, and the Loan Parties shall not have any rights to rely on or
enforce any of the provisions hereof. In performing its functions and duties under this Agreement,
the Agent shall act solely as agent of the Banks and does not assume and shall not be deemed to
have assumed any obligation toward or relationship of agency or trust with or for any of the Loan
Parties.

11. MISCELLANEOUS

     11.1 Modifications, Amendments or Waivers.

          With the written consent of the Required Banks, the Agent, acting on behalf of all the Banks,
and the Borrower, on behalf of the Loan Parties, may from time to time enter into written
agreements amending or changing any provision of this Agreement or any other Loan Document or the
rights of the Banks or the Loan Parties hereunder or thereunder, or may grant written waivers or
consents to a departure from the due performance of the Obligations of the Loan Parties hereunder
or thereunder. Any such agreement, waiver or consent made with such written consent shall be
effective to bind all the Banks and the Loan Parties; provided, that, without the written consent
of all the Banks, no such agreement, waiver or consent may be made which will:

          11.1.1 Increase of Commitment; Extension of Expiration Date.

               Increase the amount of the Revolving Credit Commitment of any Bank hereunder or extend the
Expiration Date;

110

 

          11.1.2 Extension of Payment; Reduction of Principal Interest or Fees; Modification of
Terms of Payment.

               Whether or not any Loans are outstanding, extend the time for payment of principal or interest
of any Loan (excluding the due date of any mandatory prepayment of a Loan or any mandatory
Commitment reduction in connection with such a mandatory prepayment hereunder except for mandatory
reductions of the Commitments on the Expiration Date), the Commitment Fee or any other fee payable
to any Bank, or reduce the principal amount of or the rate of interest borne by any Loan or reduce
the Commitment Fee or any other fee payable to any Bank, or otherwise affect the terms of payment
of the principal of or interest of any Loan, the Commitment Fee or any other fee payable to any
Bank;

          11.1.3 Release of Collateral or Guarantor.

               Except for sales of assets permitted by Section 8.2.7 [Disposition of Assets or Subsidiaries],
release any Collateral consisting of capital stock or other ownership interests of any Loan Party
or its Subsidiary or substantially all of the assets of any Loan Party, any Guarantor from its
Obligations under the Guaranty Agreement or any other security for any of the Loan Parties’
Obligations; or

          11.1.4 Miscellaneous.

               Amend Section 5.2 [Pro Rata Treatment of Banks], 10.6 [Exculpatory Provisions, Etc.] or 10.13
[Equalization of Banks] or this Section 11.1, alter any provision regarding the pro rata treatment
of the Banks, change the definition of Required Banks, or change any requirement providing for the
Banks or the Required Banks to authorize the taking of any action hereunder;

provided that no agreement, waiver or consent which would modify the interests, rights or
obligations of the Agent or the Issuing Bank without the written consent of such Agent or Issuing
Bank, as applicable, and provided, further that, if in connection with any proposed waiver,
amendment or modification referred to in Sections 11.1.1 through 11.1.4 above, the consent of the
Required Banks is obtained but the consent of one or more of such other Banks whose consent is
required is not obtained (each a “Non-Consenting Bank”), then the Borrower shall have the right to
replace any such Non-Consenting Bank with one or more replacement Banks pursuant to Section 5.4.2
[Replacement of a Bank].

     11.2 No Implied Waivers; Cumulative Remedies; Writing Required.

          No course of dealing and no delay or failure of the Agent or any Bank in exercising any right,
power, remedy or privilege under this Agreement or any other Loan Document shall affect any other
or future exercise thereof or operate as a waiver thereof, nor shall any single or partial exercise
thereof or any abandonment or discontinuance of steps to enforce such a right, power, remedy or
privilege preclude any further exercise thereof or of any other right, power, remedy or privilege.
The rights and remedies of the Agent and the Banks under this Agreement and any other Loan
Documents are cumulative and not exclusive of any rights or remedies which they would otherwise
have. Any waiver, permit, consent or approval of any kind or character on the part of any Bank of
any breach or default under this Agreement or

111

 

any such waiver of any provision or condition of this Agreement must be in writing and shall
be effective only to the extent specifically set forth in such writing.

     11.3 Reimbursement and Indemnification of Banks by the Borrower; Taxes.

          11.3.1 Payments Free of Taxes.
Any and all payments by or on account of any obligation of the Borrower hereunder or under any
other Loan Document shall be made free and clear of and without reduction or withholding for any
Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required by applicable Law
to deduct any Indemnified Taxes (including any Other Taxes) from such payments, then (i) the sum
payable shall be increased as necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this Section) the Agent, Bank or Issuing
Bank, as the case may be, receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall
timely pay the full amount deducted to the relevant Official Body in accordance with applicable
Law.

          11.3.2 Payment of Other Taxes by the Borrower. Without limiting the provisions of Section 11.3.1 [Payments Free of Taxes] above, the Borrower
shall timely pay any Other Taxes to the relevant Official Body in accordance with applicable Law.

          11.3.3 Indemnification by the Borrower. The Borrower shall indemnify the Agent, each Bank and the Issuing Bank, within ten (10) days after
demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified
Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section)
paid by the Agent, such Bank or the Issuing Bank, as the case may be, and any penalties, interest
and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified
Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Official Body.
A certificate as to the amount of such payment or liability, with appropriate back up
documentation, delivered to the Borrower by a Bank or the Issuing Bank (with a copy to the Agent),
or by the Agent on its own behalf or on behalf of a Bank or the Issuing Bank, shall be conclusive
absent manifest error.

          11.3.4 Reimbursement by Banks. To the extent that the Borrower for any reason fails to indefeasibly pay any amount required under
Sections 5.6.1 [Costs and Expenses] or 11.3.3 [Indemnification by the Borrower] to be paid by it to
the Agent (or any sub-agent thereof), the Issuing Bank or any Related Party of any of the
foregoing, each Bank severally agrees to pay to the Agent (or any such sub-agent), the Issuing Bank
or such Related Party, as the case may be, such Bank’s Ratable Share (determined as of the time
that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount,
provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related
expense, as the case may be, was incurred by or asserted against the Agent (or any such sub-agent)
or the Issuing Bank in its capacity as such, or against any Related Party of
any of the foregoing acting for the Agent (or any such sub-agent) or Issuing Bank in connection
with such capacity.

          11.3.5 Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a
Official Body, the Borrower shall deliver to the Agent the original or a certified copy of a
receipt issued by such Official Body

112

 

evidencing such payment, a copy of the return reporting such
payment or other evidence of such payment reasonably satisfactory to the Agent.

          11.3.6 Status of Banks. Any Foreign Bank that is entitled to an exemption from or reduction of withholding tax under the
Law of the jurisdiction in which the Borrower is resident for tax purposes, or any treaty to which
such jurisdiction is a party, with respect to payments hereunder or under any other Loan Document
shall deliver to the Borrower (with a copy to the Agent), at the time or times prescribed by
applicable Law or reasonably requested by the Borrower or the Agent, such properly completed and
executed documentation prescribed by applicable Law as will permit such payments to be made without
withholding or at a reduced rate of withholding. Notwithstanding the submission of a such
documentation claiming a reduced rate of or exemption from U.S. withholding tax, the Agent shall be
entitled to withhold United States federal income taxes at the full 30% withholding rate if in its
reasonable judgment it is required to do so under the due diligence requirements imposed upon a
withholding agent under § 1.1441-7(b) of the United States Income Tax Regulations. Further, the
Agent is indemnified under § 1.1461-1(e) of the United States Income Tax Regulations against any
claims and demands of any Bank or assignee or participant of a Bank for the amount of any tax it
deducts and withholds in accordance with regulations under § 1441 of the Internal Revenue Code. In
addition, any Bank, if requested by the Borrower or the Agent, shall deliver such other
documentation prescribed by applicable Law or reasonably requested by the Borrower or the Agent as
will enable the Borrower or the Agent to determine whether or not such Bank is subject to backup
withholding or information reporting requirements.

               Without limiting the generality of the foregoing, in the event that the Borrower is resident
for tax purposes in the United States of America, any Foreign Bank shall deliver to the Borrower
and the Agent (in such number of copies as shall be requested by the recipient) on or prior to the
date on which such Foreign Bank becomes a Bank under this Agreement (and from time to time
thereafter upon the request of the Borrower or the Agent, but only if such Foreign Bank is legally
entitled to do so), whichever of the following is applicable:

          (i) duly completed copies of IRS Form W-8BEN claiming eligibility for benefits of an income
tax treaty to which the United States of America is a party,

          (ii) duly completed copies of IRS Form W-8ECI,

          (iii) in the case of a Foreign Bank claiming the benefits of the exemption for portfolio
interest under section 881(c) of the Code, (x) a certificate to the effect that such Foreign Bank
is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent
shareholder” of the Borrower within the meaning of section 881(c)(3)(B) of the Code, or
(C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y)
duly completed copies of IRS Form W-8BEN, or

          (iv) any other form prescribed by applicable Law as a basis for claiming exemption from or a
reduction in United States Federal withholding tax duly completed together with such supplementary
documentation as may be prescribed by applicable Law to permit the Borrower to determine the
withholding or deduction required to be made.

          11.3.7 Waiver of Consequential Damages, Etc. To the fullest extent permitted by applicable Law, the Borrower shall not assert, and hereby
waives, any claim against any

113

 

Indemnitee, on any theory of liability, for special, indirect,
consequential or punitive damages (as opposed to direct or actual damages) arising out of, in
connection with, or as a result of, this Agreement, any other Loan Document or any agreement or
instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or Letter
of Credit or the use of the proceeds thereof. No Indemnitee referred to in Section 11.3.3
[Indemnification by Borrower] shall be liable for any damages arising from the use by unintended
recipients of any information or other materials distributed by it through telecommunications,
electronic or other information transmission systems in connection with this Agreement or the other
Loan Documents or the transactions contemplated hereby or thereby.

     11.4 Holidays.

          Whenever payment of a Loan to be made or taken hereunder shall be due on a day which is not a
Business Day such payment shall be due on the next Business Day (except as provided in Section 4.2
[Interest Periods] with respect to Interest Periods under the Libor-Rate Option) and such extension
of time shall be included in computing interest and fees, except that the Loans shall be due on the
Business Day preceding the Expiration Date if the Expiration Date is not a Business Day. Whenever
any payment or action to be made or taken hereunder (other than payment of the Loans) shall be
stated to be due on a day which is not a Business Day, such payment or action shall be made or
taken on the next following Business Day, and such extension of time shall not be included in
computing interest or fees, if any, in connection with such payment or action.

     11.5 Funding by Branch, Subsidiary or Affiliate.

          11.5.1 Notional Funding.

               Each Bank shall have the right from time to time, without notice to the Borrower, to deem any
branch, Subsidiary or Affiliate (which for the purposes of this Section 11.5 shall mean any
corporation or association which is directly or indirectly controlled by or is under direct or
indirect common control with any corporation or association which directly or indirectly controls
such Bank) of such Bank to have made, maintained or funded any Loan to which the Libor-Rate Option
applies at any time, provided that immediately following (on the assumption that a payment were
then due from the Borrower to such other office), and as a result of such change, the Borrower
would not be under any greater financial obligation pursuant to Section 5.6 [Additional
Compensation in Certain Circumstances] or for Additional Taxes than it would have been in the
absence of such change. Notional funding offices may be selected by each Bank without regard to such Bank’s actual methods of making, maintaining or
funding the Loans or any sources of funding actually used by or available to such Bank.

          11.5.2 Actual Funding.

               Each Bank shall have the right from time to time to make or maintain any Loan by arranging for
a branch, Subsidiary or Affiliate of such Bank to make or maintain such Loan subject to the last
sentence of this Section 11.5.2. If any Bank causes a branch, Subsidiary or Affiliate to make or
maintain any part of the Loans hereunder, all terms and conditions of this Agreement shall, except
where the context clearly requires otherwise, be applicable to such part of the Loans to the same
extent as if such Loans were made or maintained by such Bank, but in no event shall any Bank’s use
of such a branch, Subsidiary or Affiliate to make or maintain any

114

 

part of the Loans hereunder cause
such Bank or such branch, Subsidiary or Affiliate to incur any cost or expenses payable by the
Borrower hereunder or require the Borrower to pay any other compensation to any Bank (including any
expenses incurred or payable pursuant to Section 5.6 [Additional Compensation in Certain
Circumstances]) which would otherwise not be incurred.

     11.6 Notices.

          11.6.1 Notices Generally. Except in the case of notices and other communications expressly permitted to be given by telephone

for the recipient). Notices delivered through electronic communications to the extent provided in
Section 11.6.2 [Electronic Communications], shall be effective as provided in such Section.

          11.6.2 Electronic Communications. Notices and other communications to the Banks and the Issuing Bank hereunder may be delivered or
furnished by electronic communication (including e-mail and Internet or intranet websites) pursuant
to procedures approved by the Agent; provided that the foregoing shall not apply to notices to any
Bank or the Issuing Bank if such Bank or the Issuing Bank, as applicable, has notified the Agent
that it is incapable of receiving notices under such Article by electronic communication. The
Agent or the Borrower may, in its discretion, agree to accept notices and other communications to

approval of such procedures may be limited to particular notices or communications. Unless the
Agent otherwise prescribes, (i) notices and other communications sent to an e-mail address shall be

acknowledgement from the intended recipient (such as by the “return receipt requested” function, as
available, return e-mail or other written acknowledgement); provided that if such notice or other
communication is not sent during the normal business hours of the recipient, such notice or
communication shall be deemed to have been sent at the opening of business on the next Business Day
for the recipient, and (ii) notices or communications posted to an Internet or intranet website

     11.7 Severability.

          The provisions of this Agreement are intended to be severable. If any provision of this
Agreement shall be held invalid or unenforceable in whole or in part in any jurisdiction, such
provision shall, as to such jurisdiction, be ineffective to the extent of such invalidity or
unenforceability without in any manner affecting the validity or enforceability thereof in any
other jurisdiction or the remaining provisions hereof in any jurisdiction.

117

 

Etc.], 10.7 [Reimbursement of Agent by Banks,
Etc.] and 11.3 [Reimbursement of Banks by Borrower; Etc.], shall survive payment in full of the
Loans, expiration or termination of the Letters of Credit and termination of the Commitments.

     11.11 Successors and Assigns.

          11.11.1 Successors and Assigns Generally. 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, except that neither the
Borrower nor any other Loan Party may assign or otherwise transfer any of its rights or obligations
hereunder without the prior written consent of the Agent and each Bank and no Bank may assign or
otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in
accordance with the provisions of Section 11.11.2 [Assignments by Banks], (ii) by way of
participation in accordance with the provisions of Section 11.11.4 [Participations], or (iii) by
way of pledge or assignment of a security interest subject to the restrictions of Section 11.11.6
[Certain Pledges; Successors and Assigns Generally] (and any other attempted assignment or transfer
by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied,
shall be construed to confer upon any Person (other than the parties hereto, their respective
successors and assigns permitted hereby, Participants to the extent provided in Section 11.11.4
[Participations] and, to the extent expressly contemplated hereby, the Related Parties of each of
the Agent and the Banks) any legal or equitable right, remedy or claim under or by reason of this
Agreement.

          11.11.2 Assignments by Banks. Any Bank may at any time assign to one or more assignees all or a portion of its rights and
obligations under this Agreement (including all or a portion of its Commitment and the Loans at
the time owing to it); provided that any such assignment shall be subject to the following
conditions:

          (i) Minimum Amounts.

                    (A) in the case of an assignment of the entire remaining amount of the assigning Bank’s
Commitment and the Loans at the time owing to it or in the case of an assignment to a Bank, an
Affiliate of a Bank or an Approved Fund, no minimum amount need be assigned; and

                    (B) in any case not described in clause (i)(A) of this Section 11.11.2, the aggregate amount
of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the
applicable Commitment is not then in effect, the principal outstanding balance of the Loans of the
assigning Bank subject to each such assignment (determined as of the date the Assignment and
Assumption Agreement with respect to such assignment is delivered to the Agent or, if “Trade Date”
is specified in the Assignment and Assumption Agreement, as of the Trade Date) shall not be less
than $2,500,000, in the case of any assignment in respect of the Revolving Credit Commitment of the
assigning Bank, unless each of the Agent and, so long as no Event of Default has occurred and is
continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or
delayed).

          (ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a
proportionate part of all the assigning Bank’s rights and obligations under this Agreement with
respect to the Loan or the Commitment assigned.

118

 

          (iii) Required Consents. No consent shall be required for any assignment except for the
consent of the Agent (which shall not be unreasonably withheld or delayed) and:

                    (A) the consent of the Borrower (such consent not to be unreasonably withheld or delayed)
shall be required unless (x) an Event of Default has occurred and is continuing at the time of such
assignment or (y) such assignment is to a Bank, an Affiliate of a Bank or an Approved Fund;

                    (B) the consent of the Issuing Bank (such consent not to be unreasonably withheld or delayed)
shall be required for any assignment that increases the obligation of the assignee to participate
in exposure under one or more Letters of Credit (whether or not then outstanding).

          (iv) Assignment and Assumption Agreement. The parties to each assignment shall execute and
deliver to the Agent an Assignment and Assumption Agreement, together with a processing and
recordation fee of $3,500, and the assignee, if it is not a Bank, shall deliver to the Agent an
administrative questionnaire provided by the Agent.

          (v) No Assignment to Borrower. No such assignment shall be made to the Borrower or any of the
Borrower’s Affiliates or Subsidiaries.

          (vi) No Assignment to Natural Persons. No such assignment shall be made to a natural person.

Subject to acceptance and recording thereof by the Agent pursuant to Section 11.11.3 [Register],
from and after the effective date specified in each Assignment and Assumption Agreement, the
assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned
by such Assignment and Assumption Agreement, have the rights and obligations of a Bank under this
Agreement, and the assigning Bank thereunder shall, to the extent of the interest assigned by such
Assignment and Assumption Agreement, be released from its obligations under this Agreement (and, in
the case of an Assignment and Assumption Agreement covering all of the assigning Bank’s rights and
obligations under this Agreement, such Bank shall cease to be a party hereto) but shall continue to
be entitled to the benefits of Sections 4.4 [LIBOR Rate Unascertainable; Illegality; Increased
Costs; Deposits Not Available], 5.6 [Additional Compensation in Certain Circumstances], and 11.3
[Reimbursements and Indemnification of the Banks by the Borrower; Taxes] with respect to facts and
circumstances occurring prior to the effective date of such assignment. Any assignment or transfer
by a Bank of rights or obligations under this Agreement that does not comply with this Section
11.11.2 shall be treated for purposes of this Agreement as a sale by such Bank of a participation
in such rights and obligations in accordance with Section 11.11.4 [Participations].

          11.11.3 Register. The Agent, acting solely for this purpose as an agent of the Borrower, shall maintain a record of
the names and addresses of the Banks, and the Commitments of, and principal amounts of the Loans
owing to, each Bank pursuant to the terms hereof from time to time. Such register shall be
conclusive, and the Borrower, the Agent and the Banks may treat each Person whose name is in such
register pursuant to the terms hereof as a Bank hereunder for all purposes of this Agreement,
notwithstanding notice to the contrary. Such register shall be available for inspection by the
Borrower and any Bank, at any reasonable time and from time to time upon reasonable prior notice.

119

 

          11.11.4 Participations. Any Bank may at any time, without the consent of, or notice to, the Borrower or the Agent, sell
participations to any Person (other than a natural person or the Borrower or any of the Borrower’s
Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Bank’s rights
and/or obligations under this Agreement (including all or a portion of its Commitment and/or the
Loans owing to it); provided that (i) such Bank’s obligations under this Agreement shall remain
unchanged, (ii) such Bank shall remain solely responsible to the other parties hereto for the
performance of such obligations and (iii) the Borrower, the Agent and the Banks, Issuing Bank shall
continue to deal solely and directly with such Bank in connection with such Bank’s rights and
obligations under this Agreement.

               Any agreement or instrument pursuant to which a Bank sells such a participation shall provide
that such Bank 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 Bank will not, without the consent of the Participant, agree to
any amendment, modification or waiver with respect to Sections 11.1.1 [Increase of Commitment,
Etc.], 11.1.2 [Extension of Payment, Etc.], or 11.1.3 [Release of Collateral or Guarantor]).
Subject to Section 11.11.5 [Limitations upon Participant Rights Successors and Assigns Generally],
the Borrower agrees that each Participant shall be entitled to the benefits of Sections 4.4 [LIBOR
Rate Unascertainable; Illegality; Increased Costs; Deposits Not Available] and 5.6 [Additional
Compensation in Certain Circumstances] and 11.3 [Reimbursement and Indemnification of the Banks by
the Borrower; Taxes] to the same extent as
if it were a Bank and had acquired its interest by assignment pursuant to Section 11.11.2
[Assignments by Banks]. To the extent permitted by Law, each Participant also shall be entitled to
the benefits of Section 9.2.3 [Setoff] as though it were a Bank; provided such Participant agrees
to be subject to Section 5.2 [Pro-Rata Treatment of Banks] as though it were a Bank.

          11.11.5 Limitations upon Participant Rights Successors and Assigns Generally. A Participant shall not be entitled to receive any greater payment under Sections 5.6 [Additional
Compensation in Certain Circumstances], 4.4 [LIBOR Rate Unascertainable; Illegality; Increased
Costs; Persons Not Available] and 11.3 [Reimbursement and Indemnification of the Banks by the
Borrower; Taxes] than the applicable Bank would have been entitled to receive with respect to the
participation sold to such Participant, unless the sale of the participation to such Participant is
made with the Borrower’s prior written consent. A Participant that would be a Foreign Bank if it
were a Bank shall not be entitled to the benefits of Section 11.3 [Reimbursement and
Indemnification of the Banks by the Borrower; Taxes] unless the Borrower is notified of the
participation sold to such Participant and such Participant agrees, for the benefit of the
Borrower, to comply with Section 11.3.6 [Status of Banks] as though it were a Bank.

          11.11.6 Certain Pledges; Successors and Assigns Generally. Any Bank 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 Bank, including any pledge or assignment to
secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall
release such Bank from any of its obligations hereunder or substitute any such pledgee or assignee
for such Bank as a party hereto.

     11.12 Confidentiality.

120

 

          11.12.1 General.

               The Agent and the Banks each agree to keep confidential all information obtained from any Loan
Party or its Subsidiaries which is nonpublic and confidential or proprietary in nature (including
any information the Borrower specifically designates as confidential), except as provided below,
and to use such information only in connection with their respective capacities under this
Agreement and for the purposes contemplated hereby. The Agent and the Banks shall be permitted to
disclose such information (i) to outside legal counsel, accountants and other professional advisors
who need to know such information in connection with the administration and enforcement of this
Agreement, subject to agreement of such Persons to maintain the confidentiality, (ii) to assignees
and participants as contemplated by Section 11.11, and prospective assignees and participants,
(iii) to the extent requested by any bank regulatory authority or, with notice to the Borrower, as
otherwise required by applicable Law or by any subpoena or similar legal process, or in connection
with any investigation or proceeding arising out of the transactions contemplated by this
Agreement, (iv) if it becomes publicly available other than as a result of a breach of this
Agreement or becomes available from a source not known to be subject to confidentiality
restrictions, or (v) if the Borrower shall have consented to such disclosure. Notwithstanding
anything herein to the contrary, the information subject to this Section 11.12.1 shall not include,
and the Agent and each Bank may disclose without limitation of any kind, any information with
respect to the “tax treatment” and “tax structure” (in each case, within the meaning of Treasury Regulation Section 1.6011-4) of the
transactions contemplated hereby and all materials of any kind (including opinions or other tax
analyses) that are provided to the Agent or such Bank relating to such tax treatment and tax
structure; provided that, with respect to any document or similar item that, in either case,
contains information concerning the tax treatment or tax structure of the transaction, as well as
other information, this sentence shall only apply to such portions of the document or similar items
that relate to the tax treatment or tax structure of the Loans, Letters of Credit and transactions
contemplated hereby.

          11.12.2 Sharing Information With Affiliates of the Banks.

               Each Loan Party acknowledges that from time to time financial advisory, investment banking and
other services may be offered or provided to the Borrower or one or more of its Affiliates (in
connection with this Agreement or otherwise) by any Bank or by one or more Subsidiaries or
Affiliates of such Bank and each of the Loan Parties hereby authorizes each Bank to share any
information delivered to such Bank by such Loan Party and its Subsidiaries pursuant to this
Agreement, or in connection with the decision of such Bank to enter into this Agreement, to any
such Subsidiary or Affiliate of such Bank, it being understood that any such Subsidiary or
affiliate of any Bank receiving such information shall be bound by the provisions of Section
11.12.1 as if it were a Bank hereunder. Such Authorization shall survive the repayment of the
Loans and other Obligations and the termination of the Commitments.

     11.13 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto in different
counterparts), each of which shall constitute an original, but all of which when taken together
shall constitute a single contract. This Agreement and the other Loan Documents, and any separate
letter agreements with respect to fees payable to the 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 including any prior
confidentiality agreements and

121

 

commitments. Except as provided in Section 7 [Letters of Credit],
this Agreement shall become effective when it shall have been executed by the Agent and when the
Agent shall have received counterparts hereof that, when taken together, bear the signatures of
each of the other parties hereto. Delivery of an executed counterpart of a signature page of this
Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this
Agreement.

     11.14 Agent’s or Bank’s Consent.

          Whenever the Agent’s or any Bank’s consent is required to be obtained under this Agreement or
any of the other Loan Documents as a condition to any action, inaction, condition or event, the
Agent and each Bank shall be authorized to give or withhold such consent in its sole and absolute
discretion and to condition its consent upon the giving of additional Collateral, the payment of
money or any other matter.

     11.15 Exceptions.

          The representations, warranties and covenants contained herein shall be independent of each
other, and no exception to any representation, warranty or covenant shall be
deemed to be an exception to any other representation, warranty or covenant contained herein
unless expressly provided, nor shall any such exceptions be deemed to permit any action or omission
that would be in contravention of applicable Law.

     11.16 Tax Withholding Clause.

          Each Bank or assignee or participant of a Bank that is not incorporated under the Laws of the
United States of America or a state thereof agrees that it will deliver to each of the Borrower and
the Agent two (2) duly completed copies of the following: (i) if any lending office of such Bank
is located in the United States,  Internal Revenue Service Form W-8ECI (“Form W-8ECI”), and
Internal Revenue Service Form W-9 (“Form W-9”), or other applicable form prescribed by the Internal
Revenue Service, and/or (ii)  if any lending office of such Bank is located outside the United
States Internal Revenue Service Form W-8BEN (“Form W-8BEN”) and Internal Revenue Service Form W-8
or any successor thereto, certifying that such Bank, assignee or participant is entitled to
receive payments under this Agreement and the other Loan Documents without deduction or withholding
of any United States federal income taxes, or is subject to such tax at a reduced rate under an
applicable tax treaty or indicating that no such exemption or reduced rate is allowable with
respect to such payments. Each Bank, assignee or participant required to deliver to the Borrower
and the Agent a form or certificate pursuant to the preceding sentence shall deliver such form or
certificate as follows: (A) each Bank which is a party hereto on the Closing Date shall deliver
such form or certificate at least five (5) Business Days prior to the first date on which any
interest or fees are payable by the Borrower hereunder for the account of such Bank; (B) each
assignee or participant shall deliver such form or certificate at least five (5) Business Days
before the effective date of such assignment or participation (unless the Agent in its sole
discretion shall permit such assignee or participant to deliver such form or certificate less than
five (5) Business Days before such date in which case it shall be due on the date specified by the
Agent). Each Bank, assignee or participant which so delivers a Form W-8ECI, Form W-9, Form W-8BEN
or Form W-8 or any applicable successor thereto further undertakes to deliver to each of the
Borrower and the Agent two (2) additional copies of such form (or a successor form) on or before
the date that such form expires or becomes obsolete or after the occurrence of any event requiring
a change in the most recent form

122

 

so delivered by it, and such amendments thereto or extensions or
renewals thereof as may be reasonably requested by the Borrower or the Agent, either certifying
that such Bank, assignee or participant is entitled to receive payments under this Agreement and
the other Loan Documents without deduction or withholding of any United States federal income taxes
or is subject to such tax at a reduced rate under an applicable tax treaty or stating that no such
exemption or reduced rate is allowable. The Agent shall be entitled to withhold United States
federal income taxes at the full withholding rate unless the Bank, assignee or participant
establishes an exemption or that it is subject to a reduced rate as established pursuant to the
above provisions.

     11.17 Joinder of Guarantors; Additional Security Arrangements.

          Any Subsidiary of the Borrower which is required to join this Agreement as a Guarantor
pursuant to Section 8.2.9 [Subsidiaries, Partnerships and Joint Ventures] shall execute and deliver
to the Agent (i) a Guarantor Joinder in substantially the form attached hereto as Exhibit
1.1(G)(1) pursuant to which it shall join as a Guarantor each of the documents to which the
Guarantors are parties; (ii) documents in the forms described in Section 7.1 [First Loans] modified
as appropriate to relate to such Subsidiary; and (iii) documents necessary to grant and perfect
Prior Security Interests to the Agent for the benefit of the Banks in all Collateral held by
such Subsidiary. The Loan Parties shall deliver such Guarantor Joinder and related documents
to the Agent within five (5) Business Days after the date of the filing of such Subsidiary’s
articles of incorporation if the Subsidiary is a corporation, the date of the filing of its
certificate of limited partnership if it is a limited partnership or the date of its organization
if it is an entity other than a limited partnership or corporation. In addition to and not in
limitation of the foregoing, the Loan Parties will not deliver any Guaranty, collateral, security
or other credit enhancement in respect of the Note Purchase Agreement (excluding Note Purchase
Collateral) unless, concurrently therewith, such credit enhancement is also delivered to or for the
benefit of the Banks on a pari passu basis.

     11.18 Environmental Indemnity.

          The Loan Parties (other than TWCC), jointly and severally, will indemnify, protect, hold
harmless and defend each Bank and the Collateral Agent and their respective officers, directors,
trustees, employees and agents (collectively, “Indemnitees”), from and against any and all
liabilities, costs (including, without limitation, reasonable fees and disbursements of attorneys,
consultants and experts, and costs of investigation, clean up, response, removal, remediation,
containment, restoration, treatment and disposal), claims, damages, demands, litigation, suits,
proceedings, actions, losses, obligations, penalties, fines, judgments, sums paid in settlement of
any of the above, and reasonable disbursements actually incurred by any Indemnitee arising from or
out of, or in any way connected with, (i) any failure of any representation or warranty set forth
in Section 6.1.26 [Environmental Matters] to be true and correct when made or any failure by the
Loan Parties (or any of them) to comply with any of the covenants, agreements, terms and conditions
set forth in Section 8.1.10 [Compliance with Laws] or to comply with any Environmental Law, (ii)
the manufacture, generation, refining, processing, distribution, use, sale, treatment, receipt,
storage, disposal, transport, arranging for transport or handling, or the emission, discharge,
release or threatened release into the environment, of any Regulated Substance at any time on, in,
under or above the Property or any part thereof, (iii) the presence or suspected presence of any
Regulated Substances manufactured, generated, refined, processed, distributed, sold, treated,
received, stored, disposed of, transported, arranged to be transported or handled by the Loan
Parties (or any of them) or any of their respective

123

 

Subsidiaries, or (iv) the migration, leaking,
leaching, flowing, emitting or other movement of any Regulated Substance from the Property, or any
location containing Regulated Substances manufactured, generated, refined, processed, distributed,
sold, treated, received, stored, disposed of, transported, arranged to be transported or handled by
the Loan Parties (or any of them) or any of their respective Subsidiaries to any other property;
provided, however, that any obligation of any of the Loan Parties under this Section 11.19 to any
Indemnitee shall not apply to and no obligation shall exist with respect to, any of the forgoing
which arises: (x) from and after the exercise by any of the Indemnitees (or any of their agents) of
any foreclosure right or control with respect to the Collateral, but only to the extent of
obligations arising from the activities of the successor or its agent or (y) from the gross
negligence or willful misconduct of any of the Indemnitees (or any of their agents). If at any
time a responsible officer of any Indemnitee shall have actual knowledge of an asserted liability
for which such Indemnitee would be entitled to indemnification hereunder, such Indemnitee shall
give written notice thereof to the Loan Parties ; provided, however, that no failure to
give any such notice shall relieve the Loan Parties (or any of them) of the obligation to provide
indemnification hereunder to such Indemnitee except to the extent that the Loan Parties shall have
been prevented as a consequence from assuming responsibility for the defense against or settlement
of such liability as hereinafter required. Upon
receipt of such notice, the Loan Parties shall assume full responsibility for the defense
against or settlement of any such liability, and shall consult
with such Indemnitee and advise such
Indemnitee of significant developments in connection therewith; provided, however, that (A)
such Indemnitee shall be consulted as to the legal counsel and other consultants to be employed in
respect thereof and may in its reasonable judgment veto the employment of any legal counsel or
consultant not reasonably acceptable to it and (B) if such Indemnitee shall give to the Loan
Parties notice that in its good faith judgment an important general interest of such Indemnitee is
involved in any such liability or potential liability, such Indemnitee shall have the right to
control, in consultation with the Loan Parties, the defense against such liability. The
obligations of the Loan Parties under this Section shall survive payment of any Notes and transfer
of any Notes and shall be enforceable by each Indemnitee hereunder separately or together, without
necessity of accelerating the maturity of any Notes; and any such Indemnitee seeking to enforce the
indemnification provided for hereunder may initially proceed directly against the Loan Parties (or
any of them) without first resorting to any other rights of indemnification or otherwise that it
may have.

     11.19 Finance Code Opt-Out.

          Each of the Loan Parties and the Banks each hereby agree that Chapter 346 of the Texas Finance
Code does not apply to this Credit Agreement, to the Notes issued pursuant to this Credit
Agreement, or to the account or arrangement evidenced by or provided for in this Credit Agreement.

     11.20 USA Patriot Act Notice. 

          Each Bank that is subject to the USA Patriot Act and the Agent (for itself and not on behalf
of any Bank) hereby notifies Loan Parties that pursuant to the requirements of the USA Patriot Act,
it is required to obtain, verify and record information that identifies the Loan Parties, which
information includes the name and address of Loan Parties and other information that will allow
such Bank or Agent, as applicable, to identify the Loan Parties in accordance with the USA Patriot
Act.
