MASTER AGREEMENT

dated as of December 20, 2007

National City Bank and G&E Healthcare REIT Chesterfield Rehab Hospital, LLC

have entered and/or anticipate entering into one or more transactions (each a “Transaction”)
that are or will be governed by this Master Agreement, which includes the schedule (the
“Schedule”), and the documents and other confirming evidence (each a “Confirmation”) exchanged
between the parties confirming those Transactions.

Accordingly, the parties agree as follows: —

1. Interpretation

(a) Definitions. The terms defined in Section 12 and in the Schedule will have the meanings therein
specified for the purpose of this Master Agreement.

(b) Inconsistency. In the event of any inconsistency between the provisions of the Schedule and the
other provisions of this Master Agreement, the Schedule will prevail. In the event of any
inconsistency between the provisions of any Confirmation and this Master Agreement (including the
Schedule), such Confirmation will prevail for the purpose of the relevant Transaction.

(c) Single Agreement. All Transactions are entered into in reliance on the fact that this Master
Agreement and all Confirmations form a single agreement between the parties (collectively referred
to as this “Agreement”), and the parties would not otherwise enter into any Transactions.

2. Obligations

(a) General Conditions.

(i) Each party will make each payment or delivery specified in each Confirmation
to be made by it, subject to the other provisions of this Agreement.

(ii) Payments under this Agreement will be made on the due date for value on
that date in the place of the account specified in the relevant Confirmation or otherwise
pursuant to this Agreement, in freely transferable funds and in the manner customary for
payments in the required currency. Where settlement is by delivery (that is, other than by
payment), such delivery will be made for receipt on the due date in the manner customary for
the relevant obligation unless otherwise specified in the relevant Confirmation or elsewhere
in this Agreement.

(iii) Each obligation of each party under Section 2(a)(i) is subject to (1) the condition
precedent that no Event of Default or Potential Event of Default with respect to the other
party has occurred and is continuing, (2) the condition precedent that no Early Termination
Date in respect of the relevant Transaction has occurred or been effectively designated and
(3) each other applicable condition precedent specified in this Agreement.

1

(b) Change of Account. Either party may change its account for receiving a payment or
delivery by giving notice to the other party at least five Local Business Days prior to the
scheduled date for the payment or delivery to which such change applies unless such other party
gives timely notice of a reasonable objection to such change.

(c) Netting. If on any date amounts would otherwise be payable: —

(i) in the same currency; and

(ii) in respect of the same Transaction,

by each party to the other, then, on such date, each party’s obligation to make payment of any such
amount will be automatically satisfied and discharged and, if the aggregate amount that would
otherwise have been payable by one party exceeds the aggregate amount that would otherwise have
been payable by the other party, replaced by an obligation upon the party by whom the larger
aggregate amount would have been payable to pay to the other party the excess of the larger
aggregate amount over the smaller aggregate amount.

The parties may elect in respect of two or more Transactions that a net amount will be determined
in respect of all amounts payable on the same date in the same currency in respect of such
Transactions, regardless of whether such amounts are payable in respect of the same Transaction.
The election may be made in the Schedule or a Confirmation by specifying that subparagraph (ii)
above will not apply to the Transactions identified as being subject to the election, together with
the starting date (in which case subparagraph (ii) above will not, or will cease to, apply to such
Transactions from such date). This election may be made separately for different groups of
Transactions and will apply separately to each pairing of branches or offices through which the
parties make and receive payments or deliveries.

(d) Default Interest; Other Amounts. Prior to the occurrence or effective designation of an Early
Termination Date in respect of the relevant Transaction, a party that defaults in the performance
of any payment obligation will, to the extent permitted by law and subject to Section 6(c), be
required to pay interest (before as well as after judgment) on the overdue amount to the other
party on demand in the same currency as such overdue amount, for the period from (and including)
the original due date for payment to (but excluding) the date of actual payment, at the Default
Rate. Such interest will be calculated on the basis of daily compounding and the actual number of
days elapsed. If, prior to the occurrence or effective designation of an Early Termination Date in
respect of the relevant Transaction, a party defaults in the performance of any obligation required
to be settled by delivery, it will compensate the other party on demand if and to the extent
provided for in the relevant Confirmation or elsewhere in this Agreement.

3. Representations

Each party represents to the other party (which representations will be deemed to be repeated by
each party on each date on which a Transaction is entered into) that:—

(a) Basic Representations.

(i) Status. It is duly organised and validly existing under the laws of the jurisdiction of
its organisation or incorporation and, if relevant under such laws, in good standing;

(ii) Powers. It has the power to execute this Agreement and any other documentation relating
to this Agreement to which it is a party, to deliver this Agreement and any other
documentation relating to this Agreement that it is required by this Agreement to deliver
and to perform its obligations under this Agreement and any obligations it has under any
Credit Support Document to which it is a party and has taken all necessary action to
authorise such execution, delivery and performance;

(iii) No Violation or Conflict. Such execution, delivery and performance do not violate or
conflict with any law applicable to it, any provision of its constitutional documents, any
order or judgment of any court or other agency of government applicable to it or any of its
assets or any contractual restriction binding on or affecting it or any of its assets;

2

(iv) Consents. All governmental and other consents that are required to have been
obtained by it with respect to this Agreement or any Credit Support Document to which it is
a party have been obtained and are in full force and effect and all conditions of any such
consents have been complied with; and

(v) Obligations Binding. Its obligations under this Agreement and any Credit Support
Document to which it is a party constitute its legal, valid and binding obligations,
enforceable in accordance with their respective terms (subject to applicable bankruptcy,
reorganisation, insolvency, moratorium or similar laws affecting creditors’ rights generally
and subject, as to enforceability, to equitable principles of general application
(regardless of whether enforcement is sought in a proceeding in equity or at law)).

(b) Absence of Certain Events. No Event of Default or Potential Event of Default or, to its
knowledge, Termination Event with respect to it has occurred and is continuing and no such event or
circumstance would occur as a result of its entering into or performing its obligations under this
Agreement or any Credit Support Document to which it is a party.

(c) Absence of Litigation. There is not pending or, to its knowledge, threatened against it or any
of its Affiliates any action, suit or proceeding at law or in equity or before any court, tribunal,
governmental body, agency or official or any arbitrator that is likely to affect the legality,
validity or enforceability against it of this Agreement or any Credit Support Document to which it
is a party or its ability to perform its obligations under this Agreement or such Credit Support
Document.

(d) Accuracy of Specified information. All applicable information that is furnished in writing by
or on behalf of it to the other party and is identified for the purpose of this Section 3(d) in the
Schedule is, as of the date of the information, true, accurate and complete in every material
respect.

4. Agreements

Each party agrees with the other that, so long as either party has or may have any obligation under
this Agreement or under any Credit Support Document to which it is a party:—

(a) Furnish Specified Information. It will deliver to the other party any forms, documents or
certificates specified in the Schedule or any Confirmation by the date specified in the Schedule or
such Confirmation or, if none is specified, as soon as reasonably practicable.

(b) Maintain Authorisations. It will use all reasonable efforts to maintain in full force and
effect all consents of any governmental or other authority that are required to be obtained by it
with respect to this Agreement or any Credit Support Document to which it is a party and will use
all reasonable efforts to obtain any that may become necessary in the future.

(c) Comply with Laws. It will comply in all material respects with all applicable laws and orders
to which it may be subject if failure so to comply would materially impair its ability to perform
its obligations under this Agreement or any Credit Support Document to which it is a party.

5. Events of Default and Termination Events

(a) Events of Default. The occurrence at any time with respect to a party or, if applicable, any
Credit Support Provider of such party or any Specified Entity of such party of any of the following
events constitutes an event of default (an “Event of Default”) with respect to such party:—

(i) Failure to Pay or Deliver. Failure by the party to make, when due, any payment under
this Agreement or delivery under Section 2(a)(i) or 2(d) required to be made by it if such
failure is not remedied on or before the third Local Business Day after notice of such
failure is given to the party;

(ii) Breach of Agreement. Failure by the party to comply with or perform any agreement or
obligation (other than an obligation to make any payment under this Agreement or delivery
under Section 2(a)(i) or 2(d) or to give notice of a Termination Event) to be complied with
or performed

3

by the party in accordance with this Agreement if such failure is not remedied on or before
the thirtieth day after notice of such failure is given to the party;

(iii) Credit Support Default.

(1) Failure by the party or any Credit Support Provider of such party to comply with
or perform any agreement or obligation to be complied with or performed by it in
accordance with any Credit Support Document if such failure is continuing after any
applicable grace period has elapsed;

(2) the expiration or termination of such Credit Support Document or the failing or
ceasing of such Credit Support Document to be in full force and effect for the
purpose of this Agreement (in either case other than in accordance with its terms)
prior to the satisfaction of all obligations of such party under each Transaction to
which such Credit Support Document relates without the written consent of the other
party; or

(3) the party or such Credit Support Provider disaffirms, disclaims, repudiates or
rejects, in whole or in part, or challenges the validity of, such Credit Support
Document;

(iv) Misrepresentation . A representation made or repeated or deemed to have been made or
repeated by the party or any Credit Support Provider of such party in this Agreement or any
Credit Support Document proves to have been incorrect or misleading in any material respect
when made or repeated or deemed to have been made or repeated;

(v) Default under Specified Transaction. The party, any Credit Support Provider of such
party or any applicable Specified Entity of such party (1) defaults under a Specified
Transaction and, after giving effect to any applicable notice requirement or grace period,
there occurs a liquidation of, an acceleration of obligations under, or an early termination
of, that Specified Transaction, (2) defaults, after giving effect to any applicable notice
requirement or grace period, in making any payment or delivery due on the last payment,
delivery or exchange date of, or any payment on early termination of, a Specified
Transaction (or such default continues for at least three Local Business Days if there is no
applicable notice requirement or grace period) or (3) disaffirms, disclaims, repudiates or
rejects, in whole or in part, a Specified Transaction (or such action is taken by any person
or entity appointed or empowered to operate it or act on its behalf);

(vi) Cross Default. If “Cross Default” is specified in the Schedule as applying to the
party, the occurrence or existence of (1) a default, event of default or other similar
condition or event (however described) in respect of such party, any Credit Support Provider
of such party or any applicable Specified Entity of such party under one or more agreements
or instruments relating to Specified Indebtedness of any of them (individually or
collectively) in an aggregate amount of not less than the applicable Threshold Amount (as
specified in the Schedule) which has resulted in such Specified Indebtedness becoming, or
becoming capable at such time of being declared, due and payable under such agreements or
instruments, before it would otherwise have been due and payable or (2) a default by such
party, such Credit Support Provider or such Specified Entity (individually or collectively)
in making one or more payments on the due date thereof in an aggregate amount of not less
than the applicable Threshold Amount under such agreements or instruments (after giving
effect to any applicable notice requirement or grace period);

(vii) Bankruptcy. The party, any Credit Support Provider of such party or any applicable
Specified Entity of such party:—

(1) is dissolved (other than pursuant to a consolidation, amalgamation or merger);
(2) becomes insolvent or is unable to pay its debts or fails or admits in writing
its inability generally to pay its debts as they become due; (3) makes a general
assignment, arrangement or composition with or for the benefit of its creditors; (4)
institutes or has instituted against it a proceeding seeking a judgment of
insolvency or bankruptcy or any other relief under any bankruptcy or insolvency law
or other similar law affecting creditors’ rights, or a petition is presented for its

4

winding-up or liquidation, and, in the case of any such proceeding or petition
instituted or presented against it, such proceeding or petition (A) results in a
judgment of insolvency or bankruptcy or the entry of an order for relief or the making
of an order for its winding-up or liquidation or (B) is not dismissed, discharged,
stayed or restrained in each case within 30 days of the institution or presentation
thereof; (5) has a resolution passed for its winding-up, official management or
liquidation (other than pursuant to a consolidation, amalgamation or merger); (6)
seeks or becomes subject to the appointment of an administrator, provisional
liquidator, conservator, receiver, trustee, custodian or other similar official for it
or for all or substantially all its assets; (7) has a secured party take possession of
all or substantially all its assets or has a distress, execution, attachment,
sequestration or other legal process levied, enforced or sued on or against all or
substantially all its assets and such secured party maintains possession, or any such
process is not dismissed, discharged, stayed or restrained, in each case within 30
days thereafter; (8) causes or is subject to any event with respect to it which, under
the applicable laws of any jurisdiction, has an analogous effect to any of the events
specified in clauses (1) to (7) (inclusive); or (9) takes any action in furtherance
of, or indicating its consent to, approval of, or acquiescence in, any of the
foregoing acts; or

(viii) Merger Without Assumption. The party or any Credit Support Provider of such party
consolidates or amalgamates with, or merges with or into, or transfers all or substantially
all its assets to, another entity and, at the time of such consolidation, amalgamation,
merger or transfer:

(1) the resulting, surviving or transferee entity fails to assume all the
obligations of such party or such Credit Support Provider under this Agreement or
any Credit Support Document to which it or its predecessor was a party by operation
of law or pursuant to an agreement reasonably satisfactory to the other party to
this Agreement; or

(2) the benefits of any Credit Support Document fail to extend (without the consent
of the other party) to the performance by such resulting, surviving or transferee
entity of its obligations under this Agreement.

(b) Termination Events. The occurrence at any time with respect to a party or, if applicable, any
Credit Support Provider of such party or any Specified Entity of such party of any event specified
below constitutes an Illegality if the event is specified in (i) below, and, if specified to be
applicable, a Credit Event Upon Merger if the event is specified pursuant to (ii) below or an
Additional Termination Event if the event is specified pursuant to (iii) below:—

(i) Illegality. Due to the adoption of, or any change in, any applicable law after the date
on which a Transaction is entered into, or due to the promulgation of, or any change in, the
interpretation by any court, tribunal or regulatory authority with competent jurisdiction of
any applicable law after such date, it becomes unlawful (other than as a result of a breach
by the party of Section 4(b)) for such party (which will be the Affected Party):—

(1) to perform any absolute or contingent obligation to make a payment or delivery or
to receive a payment or delivery in respect of such Transaction or to comply with any
other material provision of this Agreement relating to such Transaction; or

(2) to perform, or for any Credit Support Provider of such party to perform, any
contingent or other obligation which the party (or such Credit Support Provider) has
under any Credit Support Document relating to such Transaction;

(ii) Credit Event Upon Merger. If “Credit Event Upon Merger” is specified in the Schedule
as applying to the party, such party (“X”), any Credit Support Provider of X or any
applicable Specified Entity of X consolidates or amalgamates with, or merges with or into,
or transfers all or substantially all its assets to, another entity and such action does
not constitute an event described in Section 5(a)(viii) but the creditworthiness of the
resulting, surviving or transferee entity is materially weaker than that of X, such Credit
Support Provider or such Specified Entity, as the case may be, immediately prior to such
action (and, in such event, X or its successor or transferee, as appropriate, will be the
Affected Party); or

5

(iii) Additional Termination Event. If any “Additional Termination Event” is
specified in the Schedule or any Confirmation as applying, the occurrence of such event
(and, in such event, the Affected Party or Affected Parties shall be as specified for such
Additional Termination Event in the Schedule or such Confirmation).

(c) Event of Default and Illegality. If an event or circumstance which would otherwise constitute
or give rise to an Event of Default also constitutes an Illegality, it will be treated as an
Illegality and will not constitute an Event of Default.

6. Early Termination

(a) Right to Terminate Following Event of Default. If at any time an Event of Default with respect
to a party (the “Defaulting Party”) has occurred and is then continuing, the other party (the
“Non-defaulting Party”) may, by not more than 20 days notice to the Defaulting Party specifying the
relevant Event of Default, designate a day not earlier than the day such notice is effective as an
Early Termination Date in respect of all outstanding Transactions. If, however, “Automatic Early
Termination” is specified in the Schedule as applying to a party, then an Early Termination Date in
respect of all outstanding Transactions will occur immediately upon the occurrence with respect to
such party of an Event of Default specified in Section 5(a)(vii)(1), (3), (5), (6) or, to the
extent analogous thereto, (8), and as of the time immediately preceding the institution of the
relevant proceeding or the presentation of the relevant petition upon the occurrence with respect
to such party of an Event of Default specified in Section 5(a)(vii)(4) or, to the extent analogous
thereto, (8).

(b) Right to Terminate Following Termination Event.

(i) Notice. If a Termination Event occurs, an Affected Party will, promptly upon becoming
aware of it, notify the other party, specifying the nature of that Termination Event and
each Affected Transaction and will also give such other information about that Termination
Event as the other party may reasonably require.

(ii) Two Affected Parties. If an Illegality under Section 5(b)(i)(1) occurs and there are
two Affected Parties, each party will use all reasonable efforts to reach agreement within
30 days after notice thereof is given under Section 6(b)(i) on action to avoid that
Termination Event.

(iii) Right to Terminate. If: —

(1) an agreement under Section 6(b)(ii) has not been effected with respect to all
Affected Transactions within 30 days after an Affected Party gives notice under
Section 6(b)(i); or

(2) an Illegality other than that referred to in Section 6(b)(ii), a Credit Event
Upon Merger or an Additional Termination Event occurs,

either party in the case of an Illegality, any Affected Party in the case of an Additional
Termination Event if there is more than one Affected Party, or the party which is not the
Affected Party in the case of a Credit Event Upon Merger or an Additional Termination Event
if there is only one Affected Party may, by not more than 20 days notice to the other party
and provided that the relevant Termination Event is then continuing, designate a day not
earlier than the day such notice is effective as an Early Termination Date in respect of all
Affected Transactions.

(c) Effect of Designation.

(i) If notice designating an Early Termination Date is given under Section 6(a) or (b), the
Early Termination Date will occur on the date so designated, whether or not the relevant
Event of Default or Termination Event is then continuing.

6

(ii) Upon the occurrence or effective designation of an Early Termination Date, no
further payments or deliveries under Section 2(a)(i) or 2(d) in respect of the Terminated
Transactions will be required to be made, but without prejudice to the other provisions of
this Agreement. The amount, if any, payable in respect of an Early Termination Date shall be
determined pursuant to Section 6(e).

(d) Calculations.

(i) Statement. On or as soon as reasonably practicable following the occurrence of an Early
Termination Date, each party will make the calculations on its part, if any, contemplated by
Section 6(e) and will provide to the other party a statement (1) showing, in reasonable
detail, such calculations (including all relevant quotations and specifying any amount
payable under Section 6(e)) and (2) giving details of the relevant account to which any
amount payable to it is to be paid. In the absence of written confirmation from the source
of a quotation obtained in determining a Market Quotation, the records of the party
obtaining such quotation will be conclusive evidence of the existence and accuracy of such
quotation.

(ii) Payment Date. An amount calculated as being due in respect of any Early Termination
Date under Section 6(e) will be payable on the day that notice of the amount payable is
effective (in the case of an Early Termination Date which is designated or occurs as a
result of an Event of Default) and on the day which is two Local Business Days after the day
on which notice of the amount payable is effective (in the case of an Early Termination Date
which is designated as a result of a Termination Event). Such amount will be paid together
with (to the extent permitted under applicable law) interest thereon (before as well as
after judgment), from (and including) the relevant Early Termination Date to (but excluding)
the date such amount is paid, at the Applicable Rate. Such interest will be calculated on
the basis of daily compounding and the actual number of days elapsed.

(e) Payments on Early Termination. If an Early Termination Date occurs, the following provisions
shall apply based on the parties’ election in the Schedule of a payment measure, either “Market
Quotation” or “Loss”, and a payment method, either the “First Method” or the “Second Method”. If
the parties fail to designate a payment measure or payment method in the Schedule, it will be
deemed that “Market Quotation” or the “Second Method”, as the case may be, shall apply. The
amount, if any, payable in respect of an Early Termination Date and determined pursuant to this
Section will be subject to any Set-off.

(i) Events of Default. If the Early Termination Date results from an Event of Default:—

(1) First Method and Market Quotation. If the First Method and Market Quotation
apply, the Defaulting Party will pay to the Non-defaulting Party the excess, if a
positive number, of

(A) the sum of the Settlement Amount (determined by the Non-defaulting Party) in
respect of the Terminated Transactions and the Unpaid Amounts owing to the
Non-defaulting Party over

(B) the Unpaid Amounts owing to the Defaulting Party.

(2) First Method and Loss. If the First Method and Loss apply, the Defaulting Party
will pay to the Non-defaulting Party, if a positive number, the Non-defaulting
Party’s Loss in respect of this Agreement.

(3) Second Method and Market Quotation. If the Second Method and Market Quotation
apply, an amount will be payable equal to (A) the sum of the Settlement Amount
(determined by the Non-defaulting Party) in respect of the Terminated Transactions
and the Unpaid Amounts owing to the Non-defaulting Party less (B) the Unpaid Amounts
owing to the Defaulting Party. If that amount is a positive number, the Defaulting
Party will pay it to the Non-defaulting Party; if it is a negative number, the
Non-defaulting Party will pay the absolute value of that amount to the Defaulting
Party.

(4) Second Method and Loss. If the Second Method and Loss apply, an amount will be
payable equal to the Non-defaulting Party’s Loss in respect of this Agreement. If
that amount is a positive number, the Defaulting Party will pay it to the
Non-defaulting Party; if it is a negative

7

number, the Non-defaulting Party will pay the absolute value of that amount to
the Defaulting Party.

(ii) Termination Events. If the Early Termination Date results from a Termination Event:—

(1) One Affected Party. If there is one Affected Party, the amount payable will be
determined in accordance with Section 6(e)(i)(3), if Market Quotation applies, or
Section 6(e)(i)(4), if Loss applies, except that, in either case, references to the
Defaulting Party and to the Non-defaulting Party will be deemed to be references to
the Affected Party and the party which is not the Affected Party, respectively, and,
if Loss applies and fewer than all the Transactions are being terminated, Loss shall
be calculated in respect of all Terminated Transactions.

(2) Two Affected Parties. If there are two Affected Parties:—

(A) if Market Quotation applies, each party will determine a Settlement
Amount in respect of the Terminated Transactions, and an amount will be
payable equal to (I) the sum of (a) one-half of the difference between the
Settlement Amount of the party with the higher Settlement Amount (“X”) and
the Settlement Amount of the party with the lower Settlement Amount (“Y”)
and (b) the Unpaid Amounts owing to X less (II) the Unpaid Amounts owing to
Y; and

(B) if Loss applies, each party will determine its Loss in respect of this
Agreement (or, if fewer than all the Transactions are being terminated, in
respect of all Terminated Transactions) and an amount will be payable equal
to one-half of the difference between the Loss of the party with the higher
Loss (“X”) and the Loss of the party with the lower Loss (“Y”).

If the amount payable is a positive number, Y will pay it to X; if it is a negative
number, X will pay the absolute value of that amount to Y.

(iii) Adjustment for Bankruptcy. In circumstances where an Early Termination Date occurs
because “Automatic Early Termination” applies in respect of a party, the amount determined
under this Section 6(e) will be subject to such adjustments as are appropriate and permitted
by law to reflect any payments or deliveries made by one party to the other under this
Agreement (and retained by such other party) during the period from the relevant Early
Termination Date to the date for payment determined under Section 6(d)(ii).

(iv) Pre -Estimate. The parties agree that if Market Quotation applies an amount recoverable
under this Section 6(e) is a reasonable pre-estimate of loss and not a penalty. Such amount
is payable for the loss of bargain and the loss of protection against future risks and
except as otherwise provided in this Agreement neither party will be entitled to recover any
additional damages as a consequence of such losses.

7. Transfer

Neither this Agreement nor any interest or obligation in or under this Agreement may be transferred
(whether by way of security or otherwise) by either party without the prior written consent of the
other party, except that:—

(a) a party may make such a transfer of this Agreement pursuant to a consolidation amalgamation
with, or merger with or into, or transfer of all or substantially all its assets to, another entity
(but without prejudice to any other right or remedy under this Agreement); and

(b) a party may make such a transfer of all or any part of its interest in any amount payable to it
from

a Defaulting Party under Section 6(e).

Any purported transfer that is not in compliance with this Section will be void

8

8. Miscellaneous

(a) Entire Agreement. This Agreement constitutes the entire agreement and understanding of the
parties with respect to its subject matter and supersedes all oral communication and prior writings
with respect thereto.

(b) Amendments. No amendment, modification or waiver in respect of this Agreement will be effective
unless in writing (including a writing evidenced by a facsimile transmission) and executed by each
of the parties or confirmed by an exchange of telexes or electronic messages on an electronic
messaging system.

(c) Survival of Obligations. Without prejudice to Sections 2(a)(iii) and 6(c)(ii), the obligations
of the parties under this Agreement will survive the termination of any Transaction.

(d) Remedies Cumulative. Except as provided in this Agreement, the rights, powers, remedies and
privileges provided in this Agreement are cumulative and not exclusive of any rights, powers,
remedies and privileges provided by law.

(e) Counterparts and Confirmations.

(i) This Agreement (and each amendment, modification and waiver in respect of it) may be
executed and delivered in counterparts (including by facsimile transmission), each of which
will be deemed an original.

(ii) The parties intend that they are legally bound by the terms of each Transaction from
the moment they agree to those terms (whether orally or otherwise). A Confirmation shall be
entered into as soon as practicable and may be executed and delivered in counterparts
(including by facsimile transmission) or be created by an exchange of telexes or by an
exchange of electronic messages on an electronic messaging system, which in each case will
be sufficient for all purposes to evidence a binding supplement to this Agreement. The
parties will specify therein or through another effective means that any such counterpart,
telex or electronic message constitutes a Confirmation.

(f) No Waiver of Rights. A failure or delay in exercising any right, power or privilege in respect
of this Agreement will not be presumed to operate as a waiver, and a single or partial exercise of
any right, power or privilege will not be presumed to preclude any subsequent or further exercise,
of that right, power or privilege or the exercise of any other right, power or privilege.

(g) Headings. The headings used in this Agreement are for convenience of reference only and are not
to affect the construction of or to be taken into consideration in interpreting this Agreement.

9. Expenses

A Defaulting Party will, on demand, indemnify and hold harmless the other party for and against all
reasonable out-of-pocket expenses, including legal fees, incurred by such other party by reason of
the enforcement and protection of its rights under this Agreement or any Credit Support Document to
which the Defaulting Party is a party or by reason of the early termination of any Transaction,
including, but not limited to, costs of collection.

10. Notices

(a) Effectiveness. Any notice or other communication in respect of this Agreement may be given in
any manner set forth below (except that a notice or other communication under Section 5 or 6 may
not be given by facsimile transmission or electronic messaging system) to the address or number or
in accordance with the electronic messaging system details provided (see the Schedule) and will be
deemed effective as indicated:—

(i) if in writing and delivered in person or by courier, on the date it is delivered;

(ii) if sent by telex, on the date the recipient’s answerback is received;

9

(iii) if sent by facsimile transmission, on the date that transmission is received by
a responsible employee of the recipient in legible form (it being agreed that the burden of
proving receipt will be on the sender and will not be met by a transmission report generated
by the sender’s facsimile machine);

(iv) if sent by certified or registered mail (airmail, if overseas) or the equivalent
(return receipt requested), on the date that mail is delivered or its delivery is attempted;
or

(v) if sent by electronic messaging system, on the date that electronic message is received,

unless the date of that delivery (or attempted delivery) or that receipt, as applicable, is not a
Local Business Day or that communication is delivered (or attempted) or received, as applicable,
after the close of business on a Local Business Day, in which case that communication shall be
deemed given and effective on the first following day that is a Local Business Day.

(b) Change of Addresses. Either party may by notice to the other change the address, telex or
facsimile number or electronic messaging system details at which notices or other communications
are to be given to it.

11. Governing Law and Jurisdiction

(a) Governing Law. This Agreement will be governed by and construed in accordance with the law
specified in the Schedule.

(b) Jurisdiction. With respect to any suit, action or proceedings relating to this Agreement
(“Proceedings”), each party irrevocably: —

governed by English law, or to the non-exclusive jurisdiction of the courts of the State of
New York and the United States District Court located in the Borough of Manhattan in New
York City, if this Agreement is expressed to be governed by the laws of the State of New
York; and

applicable law, with respect to itself and its revenues and assets (irrespective of their use or
intended use), all immunity on the grounds of sovereignty or other similar grounds from (i) suit,
(ii) jurisdiction of any court, (iii) relief by way of injunction, order for specific performance

“Loss” means, with respect to this Agreement or one or more Terminated Transactions, as the case
may be, and a party, an amount that party reasonably determines in good faith to be its total
losses and costs (or gain, in which case expressed as a negative number) in connection with this
Agreement or that Terminated Transaction or group of Terminated Transactions, as the case may be,
including any loss of bargain, cost of funding or, at the election of such party but without
duplication, loss or cost incurred as a result of its terminating, liquidating, obtaining or

11

resulting from any of them). Loss includes losses and costs (or gains) in respect of any
payment or delivery required to have been made (assuming satisfaction of each applicable condition
precedent) on or before the relevant Early Termination Date and not made, except, so as to avoid

“Market Quotation” means, with respect to one or more Terminated Transactions and a party making
the determination, an amount determined on the basis of quotations from Reference Market-makers.
Each quotation will be for an amount, if any, that would be paid to such party (expressed as a
negative number) or by such party (expressed as a positive number) in consideration of an agreement
between such party (taking into account any existing Credit Support Document with respect to the
obligations of such party) and the quoting Reference Market-maker to enter into a transaction (the
“Replacement Transaction”) that would have the effect of preserving for such party the economic
equivalent of any payment or delivery (whether the underlying obligation was absolute or contingent
and assuming the satisfaction of each applicable condition precedent) by the parties under Section
2(a)(i) in respect of such Terminated Transaction or group of Terminated Transactions that would,
but for the occurrence of the relevant Early Termination Date, have been required after that date.
For this purpose, Unpaid Amounts in respect of the Terminated Transaction or group of Terminated
Transactions are to be excluded but, without limitation, any payment or delivery that would, but
for the relevant Early Termination Date, have been required (assuming satisfaction of each
applicable condition precedent) after that Early Termination Date is to be included. The
Replacement Transaction would be subject to such documentation as such party and the Reference
Market-maker may, in good faith, agree. The party making the determination (or its agent) will
request each Reference Market-maker to provide its quotation to the extent reasonably practicable
as of the same day and time (without regard to different time zones) on or as soon as reasonably
practicable after the relevant Early Termination Date. The day and time as of which those
quotations are to be obtained will be selected in good faith by the party obliged to make a
determination under Section 6(e), and, if each party is so obliged, after consultation with the
other. If more than three quotations are provided, the Market Quotation will be the arithmetic mean
of the quotations, without regard to the quotations having the highest and lowest values. If
exactly three such quotations are provided, the Market Quotation will be the quotation remaining
after disregarding the highest and lowest quotations. For this purpose, if more than one quotation
has the same highest value or lowest value, then one of such quotations shall be disregarded. If
fewer than three quotations are provided, it will be deemed that the Market Quotation in respect of
such Terminated Transaction or group of Terminated Transactions cannot be determined.

“Non-default Rate” means a rate per annum equal to the cost (without proof or evidence of any
actual cost) to the Non-defaulting Party (as certified by it) if it were to fund the relevant
amount.

“Non-defaulting Party” has the meaning specified in Section 6(a).

“Potential Event of Default” means any event which, with the giving of notice or the lapse of time
or both, would constitute an Event of Default.

“Reference Market-makers” means four leading dealers in the relevant market selected by the party
determining a Market Quotation in good faith (a) from among dealers of the highest credit standing
which satisfy all the criteria that such party applies generally at the time in deciding whether to
offer or to make an extension of credit and (b) to the extent practicable, from among such dealers
having an office in the same

city.

“Scheduled Payment Date” means a date on which a payment or delivery is to be made under Section
2(a)(i) with respect to a Transaction.

“Set-off” means set-off, offset, combination of accounts, right of retention or withholding or
similar right or requirement to which the payer of an amount under Section 6 is entitled or subject
(whether arising under

12

this Agreement, another contract, applicable law or otherwise) that is exercised by, or
imposed on, such payer.

“Settlement Amount” means, with respect to a party and any Early Termination Date, the sum of:—

(a) the Market Quotations (whether positive or negative) for each Terminated Transaction or group
of Terminated Transactions for which a Market Quotation is determined; and

(b) such party’s Loss (whether positive or negative and without reference to any Unpaid Amounts)
for each Terminated Transaction or group of Terminated Transactions for which a Market Quotation
cannot be determined or would not (in the reasonable belief of the party making the determination)
produce a commercially reasonable result.

“Specified Entity” has the meaning specified in the Schedule.

“Specified Indebtedness” means, subject to the Schedule, any obligation (whether present or future,
contingent or otherwise, as principal or surety or otherwise) in respect of borrowed money.

“Specified Transaction” means, subject to the Schedule, (a) any transaction (including an agreement

(or any Credit Support Provider of such party or any applicable Specified Entity of such party) and
the other party to this Agreement (or any Credit Support Provider of such other party or any
applicable Specified Entity of such other party) which is a rate swap transaction, basis swap,
forward rate transaction, commodity swap, commodity option, equity or equity index swap, equity or
equity index option, bond option, interest rate option, foreign exchange transaction, cap
transaction, floor transaction, collar transaction, currency swap transaction, cross-currency rate
swap transaction, currency option or any other similar transaction (including any option with
respect to any of these transactions), (b) any combination of these transactions and (c) any other
transaction identified as a Specified Transaction in this Agreement or the relevant confirmation.

“Terminated Transactions” means with respect to any Early Termination Date (a) if resulting from a
Termination Event, all Affected Transactions and (b) if resulting from an Event of Default, all
Transactions (in either case) in effect immediately before the effectiveness of the notice
designating that Early Termination Date (or, if “Automatic Early Termination” applies, immediately
before that Early Termination Date).

“Termination Event” means an Illegality or, if specified to be applicable, a Credit Event Upon
Merger or an Additional Termination Event.

“Termination Rate” means a rate per annum equal to the arithmetic mean of the cost (without proof
or evidence of any actual cost) to each party (as certified by such party) if it were to fund or of
funding such amounts.

“Unpaid Amounts” owing to any party means, with respect to an Early Termination Date, the aggregate
of (a) in respect of all Terminated Transactions, the amounts that became payable (or that would
have become payable but for Section 2(a)(iii)) to such party under Section 2(a)(i) on or prior to
such Early Termination Date and which remain unpaid as at such Early Termination Date and (b) in
respect of each Terminated Transaction, for each obligation under Section 2(a)(i) which was (or
would have been but for Section 2(a)(iii)) required to be settled by delivery to such party on or
prior to such Early Termination Date and which has not been so settled as at such Early Termination
Date, an amount equal to the fair market value of that which was (or would have been) required to
be delivered as of the originally scheduled date for delivery, in each case together with (to the
extent permitted under applicable law) interest, in the currency of such amounts, from (and
including) the date such amounts or obligations were or would have been required to have been paid
or performed to (but excluding) such Early Termination Date, at the Applicable Rate. Such amounts
of interest will be calculated on the basis of daily compounding and the actual number of days
elapsed. The fair market value of any obligation referred to in clause (b) above shall be
reasonably determined

13

by the party obliged to make the determination under Section 6(e) or, if each party is so
obliged, it shall be the average of the fair market values reasonably determined by both parties.

IN WITNESS WHEREOF the parties have executed this document on the respective dates specified below

Other Provisions

Potential Event of Default immediately upon learning of the occurrence thereof.

(b) Right To Set-off. Section 6(f) is added to the Master Agreement reading as follows:

	 	(i)	 	Set-off. Any amount (the “Early Termination Amount”) payable to one
party (the “Payee’”) by the other party (the “Payer”) under Section 6(e), in
circumstances where there is a Defaulting Party or one Affected Party in the
case where a Termination Event under Section 5(b)(iii) has occurred, will, at
the option of the party (“X”) other than the Defaulting Party or the Affected
Party (and without prior notice to the Defaulting Party or Affected Party), be
reduced by its set-off against any amount(s) (the “Other Agreement Amount”)
payable by the Payee to the Payer under any other agreement(s) between the
Payee and the Payer or instrument(s) or undertaking(s) issued or executed by
one party to, or in favor of, the other party (and the Other Agreement Amount
shall be discharged promptly and in all respects to the extent it is so
set-off), X will give notice to the other party of any set-off effected. under
this Section 6(f).	 

	 	(A)	 	If a Defaulting Party has a right to receive payment
from X and is in default under its obligations to an Affiliate of X,
then any right of the Affiliate of X to receive payment from the
Defaulting Party may be assigned to X (an “Assignment of Rights”), in
which case the Defaulting Party hereby consents to any such assignment
of the benefit of its obligations. X shall give prompt written notice
to the Defaulting Party of any Assignments of Rights by the Affiliate
of X to X pursuant to this provision.	 

	 	(B)	 	If X has a right to receive payment from the Defaulting
Party and the Defaulting Party has funds on deposit with, or otherwise
in the possession of an Affiliate of X {the “Deposit Funds”), then the
Defaulting Party consents to payment over to X. by the Affiliate of X
all of such Deposit Funds in an amount not to exceed the payment due
from Defaulting Party to X under this Agreement. The payment of Deposit
Funds pursuant to this provision shall be immediately paid upon notice
by X to the Affiliate of X that a payment is due under this provision
and the amount of such payment. X shall give prompt written notice to
the Defaulting Party of any payment to X by an Affiliate of X pursuant
to this provision.	 

If the Early Termination Amount and/or Other Agreement Amount has been
applied under clause (i) above to reduce or eliminate the obligations of the
Defaulting Party to the Affiliate of X, such application shall reduce or
eliminate the Early Termination Amount and/or Other Agreement Amount. If the
Deposit Funds have been applied under clause (ii) above to reduce or
eliminate the obligations of the Defaulting Party to X, such application
shall reduce or eliminate the Early Termination Amount and/or Other
Agreement Amount

If an obligation is unascertained, X may in good faith estimate that
obligation and set-off in respect of the estimate, subject to the relevant
party accounting to the other when the obligation is ascertained.

Nothing in this Section 6(f) shall be effective to create a charge or other
security interest. This Section 6(f) shall be without prejudice and in
addition to any right of set-off, combination of accounts, lien or other
right to which any party is at any time otherwise entitled (whether by
operation of law, contract or otherwise).

financial situation of Party B. Party B represents, which representation shall be deemed
repeated with respect to and at the time of each Transaction, that it has had the opportunity,

the Agreement and any Transaction.

recording of conversations between trading and marketing personnel of the parties to this
Agreement whether by one or other or both of the parties or their agents, and that any such

the Transaction shall be treated pari passu with all senior indebtedness, liabilities and
obligations of each such party.

2. AMOUNT AND TERMS OF THE LOANS

2.1. Revolving Credit. Each Bank agrees, on the terms and conditions hereinafter set forth, to
make its Pro Rata Share of loans (each a “Revolving Credit Loan” and collectively, the “Revolving
Credit Loans”) and issue Letters of Credit pursuant to Section 2.2. to the Borrower from time to
time during the period from the date of this Agreement up to but not including the Termination
Date, in an aggregate principal amount not to exceed at any time outstanding the amount set forth
opposite such Lender’s name on the signature pages hereto under the heading “Revolving Loan
Commitment” (such amount as the same may be reduced or increased from time to time pursuant hereto;
provided, however, that, after giving effect to the Borrowing of Revolving Loans, the Aggregate
Outstanding Credit Exposure shall not exceed the Revolving Loan Commitment. Subject to the other
terms and conditions hereof, amounts borrowed under this Section 2.1 may be repaid and reborrowed
from time to time.

Each Revolving Credit Loan which shall not utilize the Revolving Credit Commitment in full
shall be in an amount not less than One Million and No/100 Dollars ($1,000,000.00) in the case of
Base Loans, and One Million and No/100 Dollars ($1,000,000.00) in the case of LIBOR Loans. Any

which that Bank’s Commitment bears to the Revolving Credit Commitment. Pursuant to the terms and
conditions set forth herein, the Revolving Credit Loans may be outstanding as Base Loans or LIBOR
Loans. Each type of Revolving Credit Loan shall be made and maintained at such Bank’s Lending
Office for such type of Loan. The failure of any Bank to make any requested Loan to be made by it
on the date specified for such Loan shall not relieve any other Bank of its obligation (if any) to
make such Loan on such date, but no Bank shall be responsible for the failure of any other Bank to
make such Loans to be made by such other Bank.

2.2. Letters of Credit.

2.2.1. Issuance. The Agent hereby agrees for its behalf and for the other Banks, on the terms
and conditions set forth in this Agreement, to issue stand-by and commercial letters of credit
(each, a “Letter of Credit”) and to renew, extend, increase, decrease or otherwise modify each
Letter of Credit from time to time from and including the date of this Agreement and prior to the
Termination Date upon the request of Borrower; provided that immediately after each such Letter of
Credit is issued or modified, the aggregate outstanding principal amount of all outstanding Letter
of Credit Obligations shall not exceed $100,000,000, and the aggregate principal amount of all
Revolving Credit Loans and Swing Line Loans, and all outstanding Letter of Credit Obligations shall
not exceed the Revolving Credit Commitment. Each Letter of Credit shall have an expiry date not
later than one year from the date of issuance, subject to renewal terms allowing for annual
extensions, provided that in no event shall any Letter of Credit have a final expiry which is
later than the thirtieth Business Day prior to the Termination Date.

2.2.2. Notice. Subject to Section 2.2.1, Borrower shall give the Agent notice at least one (1)
Business Day prior to the proposed date of issuance or modification of each Letter of Credit,
specifying the account party (which must be Borrower or a Subsidiary), the beneficiary, the
proposed date of issuance (or modification) and the expiry date of such Letter of Credit, and
describing the proposed terms of such Letter of Credit and the nature of the transactions proposed
to be supported thereby. The issuance or modification by the Agent of any Letter of Credit shall,
in addition to the conditions precedent set forth in Section 3 (the satisfaction of which the Agent
shall have no duty to ascertain), be subject to the conditions precedent that such Letter of Credit
shall be satisfactory to the Agent and that Borrower and the account party (if other than Borrower)
shall have executed and delivered such application agreement and/or such other instruments and
agreements relating to such Letter of Credit as the Agent shall have reasonably requested (each, a
“Letter of Credit Application Agreement”). In the event of any conflict between the terms of this
Agreement and the terms of any Letter of Credit Application Agreement, the terms of this Agreement
shall control.

2.2.3. Letter of Credit Fees. Borrower shall pay a fee to Agent, for the pro-rata benefit of
all Banks, equal to, as of any date of determination thereof, the amount set forth on the Pricing
Schedule. Additionally, Borrower shall pay to the Agent for the benefit of the issuing Bank(s) on
a pro-rata basis an issuance fee equal to 0.125% of the face amount of the Letter of Credit upon
the issuance thereof.

2.2.4. Administration. Upon receipt from the beneficiary of any demand for payment under any
Letter of Credit, the Agent shall promptly notify Borrower as to the amount to be paid by the Banks
as a result of such demand and the proposed payment date (each a “Letter of Credit Payment Date”).
Each Bank shall make a Revolving Credit Loan based on its Pro Rata Share, the proceeds of which
shall be used to pay the applicable Letter of Credit. The responsibility of the Agent to Borrower
shall be only to determine that the documents (including each demand for payment) delivered under
each Letter of Credit in connection with such presentment shall be in conformity in all material
respects with such Letter of Credit.

2.2.5. Reimbursement. Borrower and any other applicable account party shall be irrevocably and
unconditionally obligated to reimburse the Agent on or by the applicable Letter of Credit Payment
Date for any amounts to be paid by the Agent upon any drawing under any Letter of Credit, without
presentment, demand, protest or other formalities of any kind. All such amounts paid by the Agent
and remaining unpaid by Borrower and any other applicable account party shall bear interest,
payable on demand, for each day until paid at a rate per annum equal to (i) the applicable Adjusted
Base Rate for such day if such day falls on or before the applicable Letter of Credit Payment Date
and (ii) the sum of 2% plus the Adjusted Base Rate applicable for such day if such day falls after
such Letter of Credit Payment Date.

2.2.6. Increased Costs. If after the date hereof, the adoption of any applicable law, rule or
regulation, or any change in any applicable law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance by the Agent with
any request or directive (whether or not having the force of law) of any such authority, central
bank or comparable agency shall impose, modify or deem applicable any tax, reserve, special deposit
or similar requirement against or with respect to or measured by reference to Letters of Credit
issued or to be issued hereunder, and the result shall be to increase the cost to the Agent of
issuing or maintaining any Letter of Credit, or reduce any amount receivable hereunder by the Agent
in respect of any Letter of Credit (which increase in cost, or reduction in amount receivable,
shall be the result of the Agent’s reasonable allocation of the aggregate of such increases or
reductions resulting from such event), then, upon demand by the Agent, Borrower agrees to pay to
the Agent, from time to time as specified by the Agent, such additional amounts as shall be
sufficient to compensate the Agent for such increased costs or reductions in amounts received by
the Agent. A certificate of the Agent submitted by the Agent to Borrower shall be conclusive as to
the amount thereof in the absence of manifest error.

2.2.7. Obligations Absolute. The obligations of Borrower and any other applicable account
parties under this Section 2.2 shall be absolute and unconditional under any and all circumstances
and irrespective of any setoff, counterclaim or defense to payment which Borrower or any of the
foregoing account parties may have or have had against the Agent or any beneficiary of a Letter of
Credit. Borrower and the applicable account parties further agree with the Agent that the
obligation for reimbursement in respect of any Letter of Credit shall not be affected by the
validity or genuineness of documents or of any endorsements thereon, even if such documents should
in fact prove to be in any or all respects invalid, fraudulent or forged, or any dispute between or
among Borrower and any other applicable account parties, or any of their Affiliates, the
beneficiary of any Letter of Credit or any financing institution or other party to whom any Letter
of Credit may be transferred or any claims or defenses whatsoever of Borrower or any other
applicable account parties, or any of their Affiliates, against the beneficiary of any Letter of
Credit or any such transferee. The Agent shall not be liable for any error, omission, interruption
or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in
connection with any Letter of Credit. Borrower and any other applicable account parties agree that
any action taken or omitted by the Agent under or in connection with each Letter of Credit and the
related drafts and documents, if done in good faith and without gross negligence or willful
misconduct, shall be binding upon them and shall not put the Agent under any liability to any of
them.

2.2.8. Actions of Agent. The Agent shall be entitled to rely, and shall be fully protected in
relying upon, any Letter of Credit, draft, writing, resolution, notice, consent, certificate,
affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or
other document believed by it to be genuine and correct and to have been signed, sent or made by
the proper Person or Persons, and upon advice and statements of legal counsel, independent
accountants and other experts selected by the Agent.

2.2.9. Indemnification. Borrower hereby agrees to indemnify and hold harmless the Agent, and
its respective directors, officers and employees from and against any and all claims and damages,
losses, liabilities, costs or expenses which the Agent may incur (or which may be claimed against
the Agent by any Person whatsoever) by reason of or in connection with the execution and delivery
or transfer of or payment or failure to pay under any Letter of Credit or any actual or proposed
use of any Letter of Credit, including, without limitation, any claims, damages, losses,
liabilities, costs or expenses which the Agent may incur by reason of or on account of the Agent
issuing any Letter of Credit which specifies that the term “beneficiary” included therein includes
any successor by operation of law of the named beneficiary, but which Letter of Credit does not
require that any drawing by any such successor beneficiary be accompanied by a copy of a legal
document, satisfactory to the Agent, evidencing the appointment of such successor beneficiary;
provided that Borrower shall not be required to indemnify the Agent for any claims, damages,
losses, liabilities, costs or expenses (x) to the extent, but only to the extent, caused by (i) the
willful misconduct or gross negligence of the Agent in determining whether a request presented
under any Letter of Credit complied with the terms of such Letter of Credit or (ii) the Agent’s
failure to pay under any Letter of Credit after the presentation to it of a request strictly
complying with the terms and conditions of such Letter of Credit or (y) which are the subject of or
are incurred in connection with any litigation or proceeding with respect to which (i) Borrower or
any other applicable account parties, or their Affiliates, on the one hand, and (ii) the Agent, on
the other hand, are directly opposing parties and with respect to which a final, non-appealable
judgment has been rendered in favor of Borrower or such other applicable account party or their
Affiliates by a court of competent jurisdiction. Nothing in this Section 2.2.9 is intended to limit
the obligations of Borrower under any other provision of this Agreement.

2.3. Reduction of Commitment. With respect to the Base Revolving Credit Commitment and not the
amounts available under the accordion feature pursuant to Section 2.21, the Borrower shall have the
right, upon at least three (3) Business Days’ notice to the Agent, to terminate in whole or reduce
in part the unused portion of thereof, provided that each partial reduction shall be in the amount
of at least One Million and No/100 Dollars ($1,000,000.00), and provided further that no reduction
shall be permitted if, after giving effect thereto, and to any prepayment made therewith, the
aggregate outstanding and unpaid principal amount of the Revolving Credit Loans and Letters of
Credit shall exceed the Revolving Credit Commitment. Any reduction in part of the unused portion
of the Banks’ Commitments shall be made in the proportion that each Bank’s Commitment bears to the
Revolving Credit Commitment. The Base Revolving Credit Commitment, once reduced or terminated, may
not be reinstated.

2.4. Notice and Manner of Borrowing. The Borrower shall give the Agent notice of any Revolving
Credit Loans under this Agreement prior to 12:00 p.m. on the day of each Base Loan, and at least
three (3) Business Days before each LIBOR Loan, specifying: (1) the date of such Loan; (2) the
amount of such Loan; (3) the type of Loan; and (4) in the case of a LIBOR Loan, the duration of the
Interest Period applicable thereto. The Agent shall promptly notify each Bank of each such notice.
Not later than 1:00 p.m. on the date of such Revolving Credit Loan, each Bank will make available
to the Agent at the Agent’s Principal Office in immediately available funds, such Bank’s Pro Rata
Share of such Revolving Credit Loan. After the Agent’s receipt of such funds, not later than 1:00
p.m. on the date of such Revolving Credit Loan and upon fulfillment of the applicable conditions
set forth in Section 3, the Agent will make such Revolving Credit Loan available to the Borrower in
immediately available funds by crediting the amount thereof to the following account with the
Agent: Account styled Saia, Inc. Operating Account, No. 209908769. All times shall be based on
Central Standard Time.

All notices given under this Section 2.4 shall be irrevocable and shall be given not later
than 12:00 p.m. on the day which is not less than the number of Business Days specified above for
such notice.

2.5. Non-Receipt of Funds by Agent. Unless the Agent shall have received notice from a Bank prior
to the date on which such Bank is to provide funds to the Agent for a Loan to be made by such Bank
that such Bank will not make available to the Agent such funds, the Agent may assume that such Bank
has made such funds available to the Agent on the date of such Loan in accordance with Section 2.4
and the Agent in its sole discretion may, but shall not be obligated to, in reliance upon such
assumption, make available to the Borrower on such date a corresponding amount. If and to the
extent such Bank shall not have so made such funds available to the Agent, such Bank agrees to
repay to the Agent forthwith on demand such corresponding amount together with interest thereon,
for each day from the date such amount is made available to the Borrower by Agent until the date
such amount is repaid to the Agent, at the Federal Funds Rate set by the Agent for the correction
of errors among banks for three Business Days and thereafter at the interest rate then applicable
to the Revolving Credit Loans. If such Bank shall repay to the Agent such corresponding amount,
such amount so repaid shall constitute such Bank’s Loan for purposes of this Agreement. If such
Bank does not pay such corresponding amount forthwith upon the Agent’s demand therefor, the Agent
shall promptly notify the Borrower, and the Borrower shall immediately pay such corresponding
amount to the Agent with interest thereon, for each day from the date such amount is made available
to the Borrower until the date such amount is repaid to the Agent, at the rate of interest
applicable at the time to such proposed Loan.

Unless the Agent shall have received notice from the Borrower prior to the date on which any
payment is due to the Banks hereunder that the Borrower will not make such payment in full, the
Agent may assume that the Borrower has made such payment in full to the Agent on such date and the
Agent in its sole discretion may, but shall not be obligated to, in reliance upon such assumption,
cause to be distributed to each Bank on such due date an amount equal to the amount then due such
Bank. If and to the extent the Borrower shall not have so made such payment in full to the Agent,
each Bank shall repay to the Agent forthwith on demand such amount distributed to such Bank
together with interest thereon, for each day from the date such amount is distributed to such Bank
until the date such Bank repays such amount to the Agent, at the Federal Funds Rate set by the
Agent for the correction of errors among banks for three Business Days and thereafter at the
interest rate then applicable to the Revolving Credit Loans.

2.6. Conversions and Renewals. The Borrower may elect from time to time to convert all or a part
of one type of Loan into another type of Loan or to renew all or part of a Loan by giving the Agent
written notice by submitting to Agent an Interest Rate Election Notice, in form and content as set
forth on Schedule “2.6" hereto, at least one (1) Business Day before conversion into a Base
Loan, at least three (3) Business Days before conversion into or renewal of a LIBOR Loan,
specifying: (1) the renewal or conversion date; (2) the amount of the Loan to be converted or
renewed; (3) in the case of conversions, the type of Loan to be converted into; and (4) in the case
of renewals of or a conversion into LIBOR Loans, the duration of the Interest Period applicable
thereto, including 30, 60, 90 or 120 day durations; provided that (a) the minimum principal amount
of each Loan outstanding after a renewal or conversion shall be Two Hundred Thousand and No/100
Dollars ($200,000.00) in the case of Base Loans, and One Million and No/100 Dollars ($1,000,000.00)
in the case of LIBOR Loans; and (b) LIBOR Loans may be converted only on the last day of the
Interest Period for such Loan. The Agent shall promptly notify each Bank of each such notice. All
conversions and renewals shall be made in the proportion that each Bank’s Loan bears to the total
amount of all the Banks’ Loans. All notices given under this Section 2.6 shall be irrevocable and
shall be given not later than 10:00 a.m. (Central time) on the day which is not less than the
number of Business Days specified above for such notice. If the Borrower shall fail to give the
Agent the notice as specified above for the renewal or conversion of a LIBOR Loan prior to the end
of the Interest Period with respect thereto, such LIBOR Loan shall automatically be converted into
a Base Loan on the last day of the Interest Period for such Loan. Notwithstanding anything
provided in this Section 2.6 or in Section 2.4, Borrower shall have no more than six (6) LIBOR
Loans outstanding at any one time.

2.7. Settlement. It is agreed that each Bank’s funded portion of the Revolving Credit Loan is
intended by the Banks to be equal at all times to such Bank’s Pro Rata Share of the outstanding
Revolving Credit Loans. Notwithstanding such agreement, the Agent, and the other Banks agree
(which agreement shall not be for the benefit of or enforceable by the Borrower) that in order to
facilitate the administration of this Agreement and the other Loan Documents, settlement among them
as to the Revolving Credit Loans shall take place on a periodic basis in accordance with the
following provisions:

2.7.1. The Agent shall request settlement (“Settlement”) with the Banks on a weekly basis, or
on a more frequent basis if so determined by the Agent, (1) with respect to each outstanding
Revolving Credit Loan, and (2) with respect to collections received, in each case, by notifying the
Banks of such requested Settlement by telecopy, telephone, or other similar form of transmission,
of such requested Settlement, no later than 10:00 a.m. (Tulsa, Oklahoma time) on the date of such
requested Settlement (the “Settlement Date”). Each Bank shall make the amount of such Bank’s Pro
Rata Share of the outstanding principal amount of the Revolving Credit Loan with respect to which
Settlement is requested available to the Agent in same day funds to such account of the Agent as
the Agent may designate, not later than 3:00 p.m. (Tulsa, Oklahoma time), on the Settlement Date
applicable thereto, regardless of whether the applicable conditions precedent set forth in Section
3 have then been satisfied. Such amounts made available to the Agent shall be applied against the
amount of the applicable Revolving Credit Loan and, together with the portion of such Revolving
Credit Loan representing Bank’s Pro Rata Share thereof, shall constitute Revolving Credit Loans of
such Banks. If any such amount is not made available to the Agent by any Bank on the Settlement
Date applicable thereto, the Agent shall be entitled to recover such amount on demand from such
Bank together with interest thereon at the Federal Funds Rate for the first three (3) days from and
after such demand and thereafter at the Interest Rate then applicable to the Revolving Credit
Loans.

2.7.2. Notwithstanding the foregoing, not more than one (1) Business Day after demand is made
by the Agent, each other Bank shall irrevocably and unconditionally purchase and receive from the
Agent, without recourse or warranty, an undivided interest and participation in such Revolving
Credit Loan to the extent of such Bank’s Pro Rata Share thereof by paying to the Agent, in same day
funds, an amount equal to such Bank’s Pro Rata Share of such Revolving Credit Loan. If such amount
is not in fact made available to the Agent by any Bank, the Agent shall be entitled to recover such
amount on demand from such Bank together with interest thereon at the Federal Funds Rate for the
first three (3) days from and after such demand and thereafter at the Interest Rate then applicable
to the Revolving Credit Loans.

2.7.3. From and after the date, if any, on which any Bank purchases an undivided interest and
participation in any Revolving Credit Loan pursuant to subsection (ii) above, the Agent shall,
subject to reimbursement to Agent for any amounts due from such Bank, promptly distribute to such
Bank at such address as such Bank may request in writing, such Bank’s Pro Rata Share of all
payments of principal and interest received by the Agent in respect of such Revolving Credit Loan.

2.7.4. The Agent shall record on its books the principal amount of the Revolving Credit Loans
owing to each Bank. In addition, each Bank is authorized, at such Bank’s option, to note the date
and amount of each payment or prepayment of principal of such Bank’s Revolving Credit Loans in its
books and records, including computer records, such books and records constituting rebuttably
presumptive evidence, absent manifest error, of the accuracy of the information contained therein.

2.7.5. All Revolving Credit Loans shall be made by the Banks simultaneously and in accordance
with their Pro Rata Shares. It is understood that (a) no Bank shall be responsible beyond such
Bank’s Commitment set forth in Section 2.1 hereof for any failure by any other Bank to perform its
obligation to make any Revolving Credit Loans hereunder, (b) no failure by any Banks to perform its
obligation to make any Revolving Credit Loan hereunder shall excuse any other Bank from its
obligation to make any Revolving Credit Loans hereunder, and (c) the obligations of each Bank
hereunder shall be several, not joint and several.

2.8. Interest. The Borrower shall pay interest to the Agent for the account of each Bank on the
outstanding and unpaid principal amount of that Bank’s Revolving Credit Loans made under this
Agreement at a rate (“Note Rate”) at all times equal to the Adjusted Base Rate for each Base Loan
and the Adjusted LIBOR Rate for each LIBOR Loan.

Any change in the Note Rate resulting from a change in the Base Rate shall be effective as of
the opening of business on the day on which such change in the Base Rate becomes effective.

Interest on each Loan shall be calculated on the basis of a year of three hundred sixty (360)
days for the actual number of days elapsed.

Interest on the Loans shall be paid in immediately available funds to the Agent at its
Principal Office for the account of the applicable Lending Office of each Bank as follows:

2.8.1. For each Base Loan on the first (1st) day of each month commencing the first
such date after such Loan and continuing until the earlier of (i) the date such Base Loan is paid
in full or (ii) the Termination Date.

2.8.2. For each LIBOR Loan, on the earlier of (i) the last day of the Interest Period with
respect to such LIBOR Loan, (ii) the first day of each calendar quarter, or (iii) the Termination
Date.

2.9. Default rate; late payment fee. If any Matured Default occurs hereunder, interest from the
date of such default shall accrue on the principal balance of all Revolving Credit Loans and on any
past due interest thereon at the rate of two percent (2%) per annum above the nondefault interest
rate accruing hereunder.

2.10. Unused Portion Fee. The Borrower agrees to pay to the Agent for the account of each Bank an
Unused Portion Fee on the average daily unused portion of such Bank’s Commitment from the date of
this Agreement until the Termination Date at a rate to be calculated, on any date of determination
thereof, as set forth on the Pricing Schedule.

Such Unused Portion Fee shall be payable in arrears on the first (1st) day of each
quarter during the term of such Bank’s Commitment, ending on the Termination Date. Upon receipt of
any Unused Portion Fees, the Agent will promptly thereafter cause to be distributed such payments
to the Banks in accordance with each Bank’s Pro Rata Share of such payments.

2.11. Notes. All Revolving Credit Loans made by each Bank under this Agreement shall be evidenced
by, and repaid with interest in accordance with, a single promissory note of the Borrower in
substantially the form of Schedule “2.11" hereto, duly completed, dated the date of this
Agreement, and payable to such Bank for the account of its applicable Lending Office, such Note to
represent the obligation of the Borrower to repay the Revolving Credit Loans. Each Bank is hereby
authorized by the Borrower to endorse on the schedule attached to the Note held by it the amount
and type of each Revolving Credit Loan and each renewal, conversion, and payment of principal
amount received by such Bank for the account of its applicable Lending Office on account of its
Revolving Credit Loans, which endorsement shall, in the absence of manifest error, be conclusive as
to the outstanding balance of the Revolving Credit Loans made by such Bank; provided, however, that
the failure to make such notation with respect to any Revolving Credit Loan or renewal, conversion,
or payment shall not limit or otherwise affect the obligations of the Borrower under this Agreement
or the Note held by such Bank. All Revolving Credit Loans shall be repaid on the Termination Date.

2.12. Payments. The Borrower may, upon at least One (1) Business Day’s notice to the Agent in the
case of Base Loans and at least Three (3) Business Days’ notice to the agent in the case of LIBOR
Loans, pay the Notes, without premium or penalty, in whole or in part with accrued interest to the
date of such payment on the amount paid, provided that LIBOR Loans may be paid, without premium or
penalty, only on the last day of the Interest Period for such Loans. Upon receipt of any such
payments, the Agent will promptly thereafter cause to be distributed such payment to each Bank for
the account of its applicable Lending Office in the proportion that each such Bank’s Loan to which
the payment applies bears to the total amount of all the Banks’ Loans to which the payment applies.

2.13. Method of Payment. The Borrower shall make each payment under this Agreement and under the
Notes not later than 3:00 p.m. (Central time) on the date when due in lawful money of the United
States to the Agent at its Principal Office for the account of the applicable Lending Office of
each Bank in immediately available funds. The Agent will promptly thereafter cause to be
distributed (1) such payments of principal and interest in like funds to each Bank for the account
of its applicable Lending Office based upon its Pro Rata Share thereof and (2) other fees payable
to any Bank to be applied in accordance with the terms of this Agreement. The Borrower hereby
authorizes each Bank, if and to the extent payment is not made when due under this Agreement or
under the Notes, to charge from time to time against any account of the Borrower with such Bank any
amount as due. Whenever any payment to be made under this Agreement or under the Notes shall be
stated to be due on a day other than a Business Day, such payment shall be made on the next
succeeding Business Day, and such extension of time shall be included in the computation of the
payment of interest and the commitment fee, as the case may be, except, in the case of a LIBOR
Loan, if the result of such extension would be to extend such payment into another calendar month,
such payment shall be made on the immediately preceding Business Day.

2.14. Use of Proceeds. The proceeds of the Loan hereunder shall be used by the Borrower for
general corporate purposes including, without limitation, purchases of treasury stock, refinancing
a portion of Borrower’s Indebtedness, financing Permitted Acquisitions, working capital, letters of
credit and capital expenditures. The Borrower will not, directly or indirectly, use any part of
such proceeds for the purpose of purchasing or carrying any margin stock within the meaning of
Regulation U of the Board of Governors of the Federal Reserve System or to extend credit to any
Persons for the purpose of purchasing or carrying any such margin stock, or for any purpose which
violates, or is inconsistent with, Regulation X of such Board of Governors.

2.15. Illegality. Notwithstanding any other provision in this Agreement, if any Bank determines
that any applicable law, rule, or regulation, or any change therein, or any change in the
interpretation or administration thereof by any governmental authority, central bank, or comparable
agency charged with the interpretation or administration thereof, or compliance by such Bank (or
its Lending Office) with any request or directive (whether or not having the force of law) of any
such authority, central bank, or comparable agency shall make it unlawful or impossible for such
Bank (or its Lending Office) to maintain or fund its LIBOR Loans, then upon thirty (30) days notice
to the Borrower (with a copy to the Agent) by such Bank the outstanding principal amount of all
LIBOR Loans, together with interest accrued thereon, and any other amounts payable to each Bank
under this Agreement shall be repaid (a) immediately upon demand of such Bank if such change or
compliance with such request, in the judgment of such Bank, requires immediate repayment, or (b) at
the expiration of the last Interest Period to expire before the effective date of any such change
or request.

2.16. Disaster. Notwithstanding anything to the contrary herein, if the Agent determines (which
determination shall be conclusive) that:

2.16.1. Quotations of interest rates for the relevant deposits referred to in the definition
of LIBOR Rate, are not being provided in the relevant amounts or for the relative maturities for
purposes of determining the rate of interest on a LIBOR Loan as provided in this Agreement; or

2.16.2. If the Majority Banks determine (which determination shall be conclusive) that the
relevant rates of interest referred to in the definition of LIBOR Rate, upon the basis of which the
rate of interest for any such type of Loan is to be determined do not accurately cover the cost to
the Banks of making or maintaining such type of Loans;

then the Agent shall forthwith give notice thereof to the Borrower, whereupon (a) the obligation of
the Banks to make LIBOR Loans, shall be suspended until the Agent notifies the Borrower that the
circumstances giving rise to such suspension no longer exist, and (b) the Borrower shall repay in
full the then outstanding principal amount of each LIBOR Loan, together with accrued interest
thereon, on the last day of the then current Interest Period applicable to such Loan.

2.17. Increased Cost. From time to time upon a thirty (30) day notice to the Borrower from a Bank
(with a copy to the Agent) the Borrower shall pay to the Agent for the account of the applicable
Bank such amounts as any Bank may determine to be necessary to compensate such Bank for any costs
incurred by such Bank which such Bank determines are attributable to its making or maintaining any
LIBOR Loans hereunder or its obligation to make any such Loans hereunder, or any reduction in any
amount receivable by such Bank under this Agreement or its Note in respect of any such Loans or
such obligation (such increases in costs and reductions in amounts receivable being herein called
“Additional Costs”), resulting from any change after the date of this Agreement in U.S. federal,
state, municipal, or foreign laws or regulations (including Regulation D), or the adoption or
making after such date of any interpretations, directives, or requirements applying to a class of
banks including such Bank of or under U.S. federal, state, municipal, or foreign laws or
regulations (whether or not having the force of law) by any court or governmental or monetary
authority charged with the interpretation or administration thereof (“Regulatory Change”), which:
(1) changes the basis of taxation of any amounts payable to such Bank under this Agreement or its
Note in respect of any of such Loans (other than taxes imposed on the overall net income of such
Bank or of its Lending Office for any of such Loans by the jurisdiction where the Principal Office
or such Lending Office is located); or (2) imposes or modifies any reserve, special deposit,
compulsory loan, or similar requirements relating to any extensions of credit or other assets of,
or any deposits with or other liabilities of, such Bank (including any of such Loans or any
deposits referred to in the definition of LIBOR Rate); or (3) imposes any other condition affecting
this Agreement or its Note (or any of such extensions of credit or liabilities). Such Bank will
notify the Borrower (with a copy to the Agent) of any event occurring after the date of this
Agreement which will entitle such Bank to compensation pursuant to this Section 2.17 as promptly as
practicable after it obtains knowledge thereof and determines to request such compensation.

Determinations by any Bank for purposes of this Section 2.17 of the effect of any Regulatory
Change on its costs of making or maintaining Loans or on amounts receivable by it in respect of
Loans, and of the additional amounts required to compensate any such Bank in respect of any
Additional Costs, shall be conclusive, provided that such determinations are made on a reasonable
basis.

2.18. Risk-Based Capital. In the event that any Bank determines that (1) compliance with any
judicial, administrative, or other governmental interpretation of any law or regulation or (2)
compliance by such Bank or any corporation controlling such Bank with any guideline or request from
any central bank or other governmental authority (whether or not having the force of law) has the
effect of requiring an increase in the amount of capital required or expected to be maintained by
such Bank or any corporation controlling such Bank, and such Bank determines that such increase is
based upon its obligations hereunder, and other similar obligations, the Borrower shall pay to the
Agent, for the account of the applicable Bank, such additional amount as shall be certified by the
Bank to be the amount allocable to such Bank’s obligations to the Borrower hereunder. Such Bank
will notify the Borrower (with a copy to the Agent) of any event occurring after the date of this
Agreement that will entitle such Bank to compensation pursuant to this Section 2.18 as promptly as
practicable after it obtains knowledge thereof and determines to request such compensation.

Determinations by any Bank for purposes of this Section 2.18 of the effect of any increase in
the amount of capital required to be maintained by such Bank and of the amount allocable to such
Bank’s obligations to the Borrower hereunder shall be conclusive, provided that such determinations
are made on a reasonable basis.

2.19. Funding Loss Indemnification. Upon notice to the Borrower from a Bank (with a copy to the
Agent) the Borrower shall pay to the Agent for the account of the applicable Bank, such amount or
amounts as shall be sufficient (in the reasonable opinion of such Bank) to compensate it for any
loss, cost, or expense incurred as a result of:

2.19.1. Any payment of a LIBOR Loan on a date other than the last day of the Interest Period
for such Loan including, but not limited to acceleration of the Loans by the Agent pursuant to
Section 8.1 or any prepayment of a LIBOR Loan under Sections 2.15 or 2.16; or

2.19.2. Any failure by the Borrower to borrow or convert, as the case may be, a LIBOR Loan on
the date for borrowing or conversion, as the case may be, specified in the relevant notice under
Section 2.6.

2.20. Swing Line Loans.

2.20.1. Amount of Swing Line Loans. Upon the satisfaction of the conditions precedent
set forth in Section 3.2 and, if such Swing Line Loan is to be made on the date of the initial
Advance hereunder, the satisfaction of the conditions precedent set forth in Section 3.1 as well,
from and including the date of this Agreement and prior to the Termination Date, the Swing Line
Lender agrees, on the terms and conditions set forth in this Agreement, to make Swing Line Loans to
the Borrower from time to time in an aggregate principal amount not to exceed the Swing Line
Commitment, provided that the Aggregate Outstanding Credit Exposure shall not at any time exceed
the aggregate Commitment, and provided further that at no time shall the Outstanding Credit
Exposure of the Swing Line Lender exceed the Swing Line Lender’s Commitment at such time. Subject
to the terms of this Agreement, the Borrower may borrow, repay and reborrow Swing Line Loans at any
time prior to the Termination Date.

2.20.2. Borrowing Notice. The Borrower shall deliver to the Agent and the Swing Line
Lender irrevocable notice (a “Swing Line Borrowing Notice”) not later than noon (Tulsa time) on the
requested date of disbursement, which shall be a Business Day (“Borrowing Date”) of each Swing Line
Loan, specifying (i) the applicable Borrowing Date, and (ii) the aggregate amount of the requested
Swing Line Loan which shall be an amount not less than $100,000. The Swing Line Loans shall bear
interest at the Adjusted Base Rate.

2.20.3. Making of Swing Line Loans. Promptly after receipt of a Swing Line Borrowing
Notice, the Swing Line Lender shall make available the Swing Line Loan, in funds immediately
available to the Borrower on the Borrowing Date.

2.20.4. Repayment of Swing Line Loans. Each Swing Line Loan shall be paid in full by
the Borrower on demand. In addition, the Swing Line Lender may at any time in its sole discretion
with respect to any outstanding Swing Line Loan, require each Bank (including the Swing Line
Lender) to make a Revolving Credit Loan in the amount of such Bank’s Pro Rata Share of such Swing
Line Loan for the purpose of repaying such Swing Line Loan. Not later than noon (Tulsa time) on
the date of any notice received pursuant to this Section 2.20.4, each Bank shall make available its
required Revolving Credit Loan, in funds immediately available in Tulsa to the Agent at its address
specified, pursuant to Section 2.4. Revolving Credit Loans made pursuant to this Section 2.20.4
shall initially be Base Loans and thereafter may be continued as Base Loans or converted into LIBOR
Loans in the manner provided in Section 2.6 and subject to the other conditions and limitations set
forth in this Section 2. Unless a Bank shall have notified the Swing Line Lender, prior to its
making any Swing Line Loan, that any applicable condition precedent set forth in Sections 3.1 or
3.2 had not then been satisfied, such Bank’s obligation to make Revolving Credit Loans pursuant to
this Section 2.20.4 to repay Swing Line Loans shall be unconditional, continuing, irrevocable and
absolute and shall not be affected by any circumstances, including, without limitation, (a) any
set-off, counterclaim, recoupment, defense or other right which such Bank may have against the
Agent, the Swing Line Lender or any other Person, (b) the occurrence or continuance of a Default,
(c) any adverse change in the condition (financial or otherwise) of the Borrower, or (d) any other
circumstances, happening or event whatsoever. In the event that any Bank fails to make payment to
the Agent of any amount due under this Section 2.20.4, the Agent shall be entitled to receive,
retain and apply against such obligation the principal and interest otherwise payable to such Bank
hereunder until the Agent receives such payment from such Bank or such obligation is otherwise
fully satisfied. In addition to the foregoing, if for any reason any Bank fails to make payment to
the Agent of any amount due under this Section 2.20.4, such Bank shall be deemed, at the option of
the Agent, to have unconditionally and irrevocably purchased from the Swing Line Lender, without
recourse or warranty, an undivided interest and participation in the applicable Swing Line Loan in
the amount of such Revolving Credit Loan, and such interest and participation may be recovered from
such Bank together with interest thereon at the Federal Funds Rate for each day during the period
commencing on the date of demand and ending on the date such amount is received. On the
Termination Date, the Borrower shall repay in full the outstanding principal balance of the Swing
Line Loans.

2.21. Accordion. Subject to the terms and conditions of this Section 2.21, and provided no Default
exists, Borrower shall have the right from time to time (but in no event more than two (2) times
during any given month) after the date hereof and before the Termination Date, upon not less than
thirty (30) Business Days’ prior written notice to Agent (such written notice being herein referred
to as a “Revolving Credit Increase Notice”), to increase on the date specified in the Revolving
Credit Increase Notice (the “Revolving Credit Increase Date”), the amount of the Revolving Credit
Commitment by the amount specified in the Revolving Credit Increase Notice (the “Revolving Credit
Increase Amount”) which shall be a minimum of $10,000,000; provided, however, that in no
event shall the amount of the Revolving Credit Loans and the aggregate Revolving Credit Commitment
be increased to an amount greater than $260,000,000, and further provided, however,
that no such Revolving Credit Increase Amount shall be permitted under this Agreement if a Default
shall exist on the date Agent receives the Revolving Credit Increase Notice or on the Revolving
Credit Increase Date. Subject to the preceding sentence, on the Revolving Credit Increase Date,
the aggregate Revolving Credit Commitment shall be increased by the Revolving Credit Increase
Amount and each Bank’s Commitment and Revolving Credit Commitment shall be increased by such Bank’s
Pro Rata Share of the Revolving Credit Increase Amount; provided, however, any such
increase is subject to the following additional conditions being satisfied in form and substance
satisfactory to Agent and its counsel: (i) Borrower shall have delivered to Agent an Amended and
Restated Revolving Credit Note payable to the order of the relevant Bank, reflecting the increased
Revolving Credit Commitment of such Bank, duly executed by Borrower; and (ii) Borrower shall have
delivered to Agent an amendment to this Agreement evidencing this Revolving Credit Increase Amount,
duly executed by Borrower, with Agent being hereby authorized by each Bank to execute such
amendment on behalf of such Bank. Notwithstanding the foregoing, (i) no Bank shall be required to
participate in any increase, and (ii) advances hereunder paid by Borrower may not be re-advanced.

2.21.1 The Agent shall promptly notify existing Banks of such request by the Borrower and each
such Bank shall have ten (10) Business Days in which to notify the Agent in writing of such Bank’s
intent to participate in such increase (each an “Existing Participating Lender”), and the amount of
such Revolving Credit Increase Amount such Existing Participating Lender is willing to commit to
(which amount shall be allocated to each Existing Participating Lender according to their existing
Pro Rata Shares should there be an over-commitment) which notice shall be irrevocable once received
by Agent. Notwithstanding the foregoing, in no event shall the Agent be obligated to agree to any
Revolving Credit Increase Amount nor shall any Bank be obligated to participate in any Revolving
Credit Increase Amount. Participation in any such Revolving Credit Increase Amount shall be
completely optional and at the sole discretion of each Bank.

2.21.2 To the extent that the entire Revolving Credit Increase Amount requested by the
Borrower and consented to by Agent is not accepted by Existing Participating Lenders, the Borrower
may propose to Agent additional new lenders acceptable to Agent (“New Lenders”) who agree to commit
to that portion of the Revolving Credit Increase Amount not accepted by Existing Participating
Lenders. Thus, any Revolving Credit Increase Amount shall be effected by an increase in any one or
more of the Existing Participating Lenders’ Commitments, and/or by the addition of the Commitments
of New Lenders(s) (in each case, the “Participating Lenders”).

2.21.3 Notwithstanding the foregoing, (i) final allocation of each Revolving Credit Increase
Amount shall be at the sole discretion of the Agent and the Borrower; and each Participating Lender
shall commit to an amount not less than $1,000,000, but shall accept any allocation amount
designated by the Borrower and the Agent that is equal to or less than its proposed portion of such
Revolving Credit Increase Amount and (ii) during the first thirty (30) Business Days following the
Closing Date, the Borrower may request Revolving Credit Increase Amount adding New Lenders upon not
less than five (5) Business Days prior written notice to the Agent, without being required to offer
any portion of such Commitment Increase to any existing Lender.

with, or result in a breach of the terms, conditions or provisions of, or constitute a default
under, or result in any violation of, or result in the creation of any Lien upon any of the
properties or assets of the Borrower or any of its Subsidiaries pursuant to, the charter or by-laws
of the Borrower or any of its Subsidiaries, any award of any arbitrator or any agreement (including
any agreement with stockholders), instrument, order, judgment, decree, statute, law, rule or
regulation to which the Borrower or any of its Subsidiaries is subject. Neither the Borrower nor

CFR Part 221) of the Board of Governors of the Federal Reserve System (“margin stock”) or for the
purpose of maintaining, reducing or retiring any Indebtedness which was originally incurred to
purchase or carry any stock that is then currently a margin stock. Neither the Borrower nor any
agent acting on its behalf has taken or will take any action which might cause this Agreement or
the Notes to violate Regulation T, Regulation U or any other regulation of the Board of Governors
of the Federal Reserve System or to violate the Exchange Act, in each case as in effect now or as
the same may hereafter be in effect.

4.10. ERISA. No accumulated funding deficiency (as defined in section 302 of ERISA and section 412
of the Code), whether or not waived, exists with respect to any Plan (other than a Multiemployer
Plan). No liability to the PBGC has been or is expected by the Borrower or any ERISA Affiliate to
be incurred with respect to any Plan (other than a Multiemployer Plan) by the Borrower, any
Subsidiary or any ERISA Affiliate which is or would be materially adverse to the business, property
or assets, condition (financial or otherwise) or operations of the Borrower and its Subsidiaries
taken as a whole. Neither the Borrower, any Subsidiary nor any ERISA Affiliate has incurred or
presently expects to incur any withdrawal liability under Title IV of ERISA with respect to any
Multiemployer Plan which is or would be materially adverse to the business, property or assets,
condition (financial or otherwise) or operations of the Borrower and its Subsidiaries taken as a
whole. The execution and delivery of this Agreement and the issuance of the Notes will be exempt
from or will not involve any transaction which is subject to the prohibitions of section 406 of
ERISA and will not involve any transaction in connection with which a penalty could be imposed
under section 502(i) of ERISA or a tax could be imposed pursuant to section 4975 of the Code.

4.11. Governmental Consent. Neither the nature of the Borrower or of any Subsidiary, nor any of
their respective businesses or properties, nor any relationship between the Borrower or any
Subsidiary and any other Person, nor any circumstance in connection with the delivery of the Notes
is such as to require any authorization, consent, approval, exemption or any action by or notice to
or filing with any court or administrative or governmental or regulatory body in connection with
the execution and delivery of this Agreement, the delivery of the Notes or fulfillment of or
compliance with the terms and provisions hereof or of the Notes.

4.12. Environmental Compliance. The Borrower and its Subsidiaries and all of their respective
properties and facilities have complied at all times and in all respects with all federal, state,
local and regional statutes, laws, ordinances and judicial or administrative orders, judgments,
rulings and regulations relating to protection of the environment except, in any such case, where
failure to comply could not result in a material adverse effect on the business, condition
(financial or otherwise) or operations of the Borrower and its Subsidiaries taken as a whole.

4.13. Utility Borrower Status. Neither the Borrower nor any Subsidiary is a (i) “holding company,”
a “subsidiary company” of a “holding company” or an “affiliate” of a “holding company” or of a
“subsidiary company” of a “holding company,” as such terms are defined in the Public Utility
Holding Company Act of 1935, as amended or (ii) public utility within the meaning of the Federal
Power Act, as amended.

4.14. Investment Company Status. Neither the Borrower nor any Subsidiary is an “investment
company” or a company “controlled” by an “investment company” within the meaning of the Investment
Company Act of 1940, as amended, or an “investment adviser” within the meaning of the Investment
Advisers Act of 1940, as amended.

4.15. Disclosure. Neither this Agreement nor any other document, certificate or statement
furnished to the Banks by or on behalf of the Borrower in connection herewith contains any untrue
statement of a material fact or omits to state a material fact necessary in order to make the
statements contained herein and therein not misleading. There is no fact peculiar to the Borrower
or any of its Subsidiaries which materially adversely affects or in the future may (so far as the
Borrower can now foresee) materially adversely affect the business, property or assets, condition
(financial or otherwise) or operations of the Borrower or any of its Subsidiaries and which has not
been set forth in this Agreement.

4.16. Hostile Tender Offers. None of the proceeds of any Notes will be used to finance a Hostile

5.1. Financial Statements; Notice of Defaults. The Borrower will deliver to Agent:

5.1.1. as soon as practicable and in any event within 45 days after the end of each quarterly

Borrower is required to file a Quarterly Report on Form 10-Q with the SEC), consolidating and
consolidated statements of income, cash flows and shareholders’ equity of the Borrower and its
Subsidiaries for the period from the beginning of the current fiscal year to the end of such

Subsidiaries as at the end of such quarterly period, setting forth in each case in comparative form
figures for the corresponding period in the preceding fiscal year, all in reasonable detail and
certified by an authorized financial officer of the Borrower, subject to changes resulting from
year-end adjustments; provided, however, that delivery pursuant to clause (3) below
of copies of the Quarterly Report on Form 10-Q of the Borrower for such quarterly period filed with
the SEC shall be deemed to satisfy the requirements of this clause (1) with respect to consolidated
financial statements so long as such statements contained in such Quarterly Report on Form 10-Q are
prepared in accordance with then current SEC and GAAP standards;

5.1.2. as soon as practicable and in any event within 120 days after the end of each fiscal
year (or, if earlier, such date as the Borrower is required to file an Annual Report on Form 10-K
with the SEC), consolidating and consolidated statements of income, cash flows and shareholders’

certified by an authorized financial officer of the Borrower; provided, however, that delivery
pursuant to clause (3) below of copies of the Annual Report on Form 10-K of the Borrower for such
fiscal year filed with the SEC shall be deemed to satisfy the requirements of this clause (2) with
respect to consolidated financial statements so long as such statements contained in such Annual
Report on Form 10-K are prepared in accordance with then current SEC and GAAP standards;

5.1.3. promptly upon transmission thereof, copies of all such financial statements, proxy
statements, notices and reports as it shall send to its public stockholders and copies of all
registration statements (without exhibits) and all reports which it files with the SEC;

5.1.4. promptly upon receipt thereof, a copy of each other report submitted to the Borrower or

and its Subsidiaries; and

5.1.6. with reasonable promptness, such other information respecting the condition or
operations, financial or otherwise, of the Borrower or any of its Subsidiaries as such holder may
reasonably request.

Together with each delivery of financial statements required by Sections 5.1 and 5.2 above,
the Borrower will deliver to Agent an Officer’s Certificate demonstrating (with computations in
reasonable detail) compliance by the Borrower and its Subsidiaries with the provisions of
Section 6.1 hereof and stating that there exists no Default or Matured Default, or, if any Default
or Matured Default exists, specifying the nature and period of existence thereof and what action
the Borrower proposes to take with respect thereto. Together with each delivery of financial
statements required by Section 5.2 above, the Borrower will deliver to Agent a certificate of such
accountants stating that, in making the audit necessary for their report on such financial
statements, they have obtained no knowledge of any Default or Matured Default, or, if they have
obtained knowledge of any Default or Matured Default, specifying the nature and period of existence
thereof. Such accountants, however, shall not be liable to anyone by reason of their failure to
obtain knowledge of any Default or Matured Default which would not be disclosed in the course of an
audit conducted in accordance with generally accepted auditing standards.

The Borrower also covenants that immediately after any Responsible Officer obtains knowledge
of a Default or Matured Default, it will deliver to Agent an Officer’s Certificate specifying the
nature and period of existence thereof and what action the Borrower proposes to take with respect
thereto.

5.2. Inspection of Property. The Borrower will permit any Person designated by any Bank in
writing, at such Bank’s expense if no Default or Matured Default exists and at the Borrower’s
expense if a Default or Matured Default does exist, to visit and inspect any of the properties of
the Borrower and its Subsidiaries, to examine the corporate books and financial records of the
Borrower and its Subsidiaries and make copies thereof or extracts therefrom and to discuss the
affairs, finances and accounts of any of such corporations with the principal officers of the
Borrower and its independent public accountants, all at such reasonable times and as often as Banks
may reasonably request.

5.3. Covenant to Secure Notes Equally. The Borrower will, if it or any Subsidiary shall create or
assume any Lien upon any of its property or assets, whether now owned or hereafter acquired, other
than, with respect to Indebtedness permitted under Section 7.2 (i) Liens affecting assets of a
company acquired by Borrower or one of its Subsidiaries (which Liens must be released and the debt
secured thereby extinguished within forty-five (45) days of the acquisition closing date), and (ii)
Liens permitted by the provisions of Section 7.1 (unless prior written consent of all the Banks to
the creation or assumption thereof shall have been obtained), make or cause to be made effective
provision whereby the Notes will be secured by such Lien equally and ratably with any and all other
Indebtedness thereby secured so long as any such other Indebtedness shall be so secured.
Notwithstanding the above, in the event, and each time, Borrower or one of its Subsidiaries
acquires one hundred percent (100%) of the outstanding stock of an entity (or entities) (each a
“Target”) which operates a primary line of business within Borrower’s core industry, the
indebtedness of such Target assumed as a result of such acquisition, and Liens affecting the assets
of such Target and securing such indebtedness, may be maintained and remain in effect for a period
of time not beyond the existing maturity date of such indebtedness; provided, however, that the
aggregate amount of assumed indebtedness from all Targets shall not exceed $25,000,000 at any one
time outstanding.

5.4. Compliance with Laws. The Borrower will, and will cause each of its Subsidiaries to, comply
with all laws, ordinances or governmental rules or regulations to which each of them is subject,
including, without limitation, Environmental Safety Laws, and will obtain and maintain in effect
all licenses, certificates, permits, franchises and other governmental authorizations necessary to
the ownership of their respective properties or to the conduct of their respective businesses, in
each case to the extent necessary to ensure that non-compliance with such laws, ordinances or
governmental rules or regulations or failures to obtain or maintain in effect such licenses,
certificates, permits, franchises and other governmental authorizations could not reasonably be
expected, individually or in the aggregate, to have a material adverse effect on the business,
condition (financial or otherwise), operations or prospects of the Borrower and its Subsidiaries
taken as a whole.

5.5. Insurance. The Borrower will, and will cause each of its Subsidiaries to, maintain, with
financially sound and reputable insurers, insurance with respect to their respective properties and
businesses against such casualties and contingencies, of such types, on such terms and in such
amounts as is customary in the case of entities of established reputations engaged in the same or a
similar business and similarly situated; and upon the written request of Agent, Borrower promptly
shall deliver evidence thereof to Agent .

5.6. Maintenance of Existence. The Borrower will, and will cause each of its Subsidiaries to, do
or cause to be done all things necessary to preserve, renew and keep in full force and effect its
corporate existence, material rights, licenses, permits and franchises; provided that
nothing in this Section 5.6 shall prevent the abandonment or termination of the existence of any
Subsidiary, or the rights or franchises of any Subsidiary or the Borrower if such abandonment or
termination would not have a material adverse effect upon the business, condition (financial or
otherwise) operations or prospects of the Borrower and its Subsidiaries taken as a whole.

5.7. Maintenance of Property. The Borrower will, and will cause each of its Subsidiaries to, at
all times maintain and preserve all property used or useful in its business in good working order
and condition, and from time to time make, or cause to be made, all needful and proper repairs,
renewals and replacements thereto, so that the business carried on in connection therewith may be
properly conducted at all times, except to the extent that the failure to do so would not have a
material adverse effect upon the business, condition (financial or otherwise), operations or
prospects of the Borrower and its Subsidiaries taken as a whole.

5.8. Payment of Taxes. The Borrower will, and will cause each of its Subsidiaries to, pay and
discharge promptly all taxes, assessments and governmental charges or levies imposed upon it or
upon its income or profits or in respect of its property, prior to the time penalties would attach
thereto, as well as lawful claims for labor, materials and supplies or otherwise which, if unpaid,
might become a Lien or charge upon such properties or any part thereof; provided,
however, that neither the Borrower nor any Subsidiary shall be required to pay and
discharge or to cause to be paid and discharged any such tax, assessment, charge, levy or claim so
long as the validity or amount thereof shall be subject to an active challenge or contest initiated
in good faith for which adequate reserves have been established in accordance with GAAP.

5.9. Parity with Other Indebtedness. The Borrower will, and will cause its Subsidiaries to,
execute all such documents and take all such reasonable actions as the Majority Banks may
reasonably request in order to assure that at all times (i) the Notes shall rank in right of
payment senior to or pari passu with all other Indebtedness of the Borrower and (ii) each
Guarantor’s guaranty obligations under the Guaranty Agreement in respect of the Notes shall rank in
right of payment senior to or pari passu with all other Indebtedness of such Subsidiary Guarantor.
Notwithstanding the above, the requirements of this Section 5.9 shall not apply to indebtedness of
a Target assumed by Borrower or one of its Subsidiaries, as allowed under Section 5.3 hereof.

5.10. ERISA. The Borrower covenants that it and each of its Subsidiaries will deliver to Agent
promptly and in any event within 10 days after it knows or has reason to know of the occurrence of
any event of the type specified in Section 8.1.14 notice of such event and the likely impact on the
Borrower and its Subsidiaries. In the event it or any Subsidiary have participated, now
participates or will participate in any Plan or Multiemployer Plan, the Borrower covenants that it
and any such Subsidiary will deliver to Agent: (i) promptly and in any event within 10 days after
it knows or has reason to know of the occurrence of a Reportable Event with respect to a Plan, a
copy of any materials required to be filed with the PBGC with respect to such Reportable Event,
together with a statement of the chief financial officer of the Borrower setting forth details as
to such Reportable Event and the action which the Borrower proposes to take with respect thereto;
(ii) at least 10 days prior to the filing by any plan administrator of a Plan of a notice of intent
to terminate such Plan, a copy of such notice; (iii) promptly upon the reasonable request of Agent,
and in no event more than 10 days after such request, copies of each annual report on Form 5500
that is filed with the Internal Revenue Service, together with certified financial statements for
the Plan (if any) as of the end of such year and actuarial statements on Schedule B to such Form
5500; (iv) promptly and in any event within 10 days after it knows or has reason to know of any
event or condition which might constitute grounds under section 4042 of ERISA for the termination
of, or the appointment of a trustee to administer, any Plan, a statement of the chief financial
officer of the Borrower describing such event or condition; (v) promptly and in no event more than
10 days after its or any ERISA Affiliate’s receipt thereof, the notice concerning the imposition of
any withdrawal liability under section 4202 of ERISA; and (vi) promptly after receipt thereof, a
copy of any notice the Borrower or any ERISA Affiliate may receive from the PBGC or the Internal

that this Section 5.10 shall not apply to notices of general application promulgated by the PBGC or
the Internal Revenue Service.

monitor the Borrower’s and its Subsidiaries’ compliance with Environmental and Safety Laws, and (B)
to minimize the Borrower’s and its Subsidiaries’ exposure to liabilities under Environmental and
Safety Laws, including, but not limited to, the Borrower’s and its Subsidiaries’ exposure to
liabilities under contracts or agreements with its customers or partners. In addition, the
environmental management system shall ensure that the Borrower’s and its Subsidiaries’ potential
exposures to liabilities under Environmental and Safety Laws are adequately insured against
pursuant to Section 5.5.

5.11.2. The Borrower will immediately notify Agent of and provide Agent with copies of any
notifications of violations or notifications of discharges or releases or threatened releases or

are received or are given or required to be given by or on behalf of the Borrower or any of its
Subsidiaries to any federal, state or local governmental agency or authority if any of the
foregoing may materially and adversely affect the Borrower or any of its Subsidiaries. Copies of
such notifications shall be delivered to Agent at the same time as they are delivered to the
governmental agency or authority.

5.11.3. The Borrower further agrees promptly to undertake and pursue diligently to completion,
or to cause its Subsidiaries to undertake and pursue diligently to completion, any appropriate and
legally required remedial containment and cleanup action in the event of any release or discharge

the Borrower or any Subsidiary.

or acting on their behalf.

5.12. Most Favored Lender Status. The Borrower will not amend the Prudential Agreement to include
one or more Additional Covenants or Additional Defaults, unless prior written consent to such
amendment shall have been obtained from all Banks; provided, however, in the event that the
Borrower or any Subsidiary shall enter into, assume or otherwise become bound by or obligated under
any such agreement without prior written consent of all Banks, the terms of this Agreement shall,
without any further action on the part of the Borrower, the Banks or the Agent, be deemed to be
amended automatically to include each Additional Covenant and each Additional Default contained in
such agreement; provided, that Agent and Banks acknowledge that the Prudential Agreement contains
or may contain financial covenants other than those set forth in Section 6., and with respect
thereto, such other financial covenants shall not be made a part hereof . The Borrower further
covenants to promptly execute and deliver at its expense (including the reasonable fees and
expenses of counsel for the Banks and the Agent) an amendment to this Agreement in form and content
satisfactory to the Banks evidencing the amendment of this Agreement to include such Additional
Covenants and Additional Defaults, provided that the execution and delivery of such amendment shall

Wholly Owned Subsidiaries and (B) sales to, or purchases from, any such Related Party of shares of

into, or be otherwise subject to, any contract, agreement or other binding obligation that directly
or indirectly limits the amount of, or otherwise restricts (i) the payment to the Borrower of
dividends or other redemptions or distributions with respect to its capital stock by any
Subsidiary, (ii) the repayment to the Borrower by any Subsidiary of intercompany loans or advances,
or (iii) other intercompany transfers to the Borrower of property or other assets by Subsidiaries.

7.12. Change of Business. The Borrower will not change, and will not permit any Subsidiary to
change, in any material respect the nature of its business or operations from the business
conducted by the Borrower and its Subsidiaries on the date hereof and will not engage, and will not
permit any Subsidiary to engage directly or indirectly in any material business activity, or
purchase or otherwise acquire any material property, in either case not directly related to the
conduct of its business or operations as presently carried on.

then, and in any such event, the Agent shall at the request of, or may, with the consent of,
the Majority Banks, by written notice to the Borrower, (1) declare the Banks’ obligation to make
Loans or issue Letters of Credit to be terminated, whereupon the same shall forthwith terminate;
(2) declare the outstanding Notes, all interest thereon, and all other amounts payable under this
Agreement to be forthwith due and payable, whereupon the Notes, all such interest, and all such
amounts shall become and be forthwith due and payable, without presentment, demand, protest, or
further notice of any kind, all of which are hereby expressly waived by the Borrower; (3) demand
that the Borrower immediately pay to the Agent the full amount then available for drawing under
each or any Letter of Credit to be held by the Agent as collateral for the Letter of Credit
Obligations pursuant to such documentation that the Agent may reasonably request, and the Borrower
agrees to immediately make such payment and acknowledges and agrees that the Banks would not have
an adequate remedy at law for failure by the Borrower to honor any such demand and that the Agent,
for the benefit of the Banks, shall have the right to require the Borrower to specifically perform
such undertaking whether or not any drawings or other demands for payment have been made under any
Letter of Credit; and (4) if such an event is an event as specified in clause (8.1.7.), (8.1.8.),
(8.1.9.), or (8.1.10.) of this Section 8.1 with respect to the Borrower, all of the Notes at the
time outstanding shall automatically become immediately due and payable at par together with
interest accrued thereon, if any, with respect to each Note, without presentment, demand, protest
or notice of any kind (including, without limitation, notice of intent to accelerate and notice of
acceleration of maturity), all of which are hereby waived by the Borrower.

Upon the occurrence and during the continuance of any Matured Default, each Bank is hereby
authorized at any time and from time to time, without notice to the Borrower (any such notice being
expressly waived by the Borrower), to set off and apply any and all deposits (general or special,
time or demand, provisional or final) at any time held and other indebtedness at any time owing by
such Bank to or for the credit or the account of the Borrower against any and all of the
obligations of the Borrower now or hereafter existing under this Agreement or the Bank’s Note or
any other Loan Document, irrespective of whether or not the Agent or such Bank shall have made any
demand under this Agreement or such Bank’s Note or such other Loan Document and although such
obligations may be unmatured. Each Bank agrees promptly to notify the Borrower (with a copy to the
Agent) after any such setoff and application, provided that the failure to give such notice shall
not affect the validity of such setoff and application. The rights of each Bank under this Section
8.1 are in addition to other rights and remedies (including, without limitation, other rights of
setoff) which each such Bank may have.

8.2. Other Remedies. If any Default or Matured Default shall occur and be continuing, each Bank
may proceed to protect and enforce its rights under this Agreement and the Notes by exercising such
remedies as are available to such Bank in respect thereof under applicable law, either by suit in
equity or by action at law, or both, whether for specific performance of any covenant or other
agreement contained in this Agreement or in aid of the exercise of any power granted in this
Agreement. No remedy conferred in this Agreement upon any Bank is intended to be exclusive of any
other remedy, and each and every such remedy shall be cumulative and shall be in addition to every
other remedy conferred herein or now or hereafter existing at law or in equity or by statute or
otherwise.

9. AGENCY PROVISIONS

9.1. Authorization and Action. Each Bank hereby appoints and authorizes the Agent to take such
action as agent on its behalf and to exercise such powers under this Agreement as are delegated to
the Agent by the terms hereof, together with such powers as are reasonably incidental thereto. The
duties of the Agent shall be mechanical and administrative in nature and the Agent shall not by
reason of this Agreement be a trustee or fiduciary for any Bank. The Agent shall have no duties or
responsibilities except those expressly set forth herein. As to any matters not expressly provided
for by this Agreement (including, without limitation, enforcement or collection of the Notes), the
Agent shall not be required to exercise any discretion or take any action, but shall be required to
act or to refrain from acting (and shall be fully protected in so acting or so refraining from
acting) upon the instructions of the Majority Banks, and such instructions shall be binding upon
all Banks and all holders of Notes; provided, however, 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
applicable law.

9.2. Liability of Agent. Neither the Agent nor any of its directors, officers, agents or employees
shall be liable for any action taken or omitted to be taken by it or them under or in connection
with this Agreement in the absence of its or their own gross negligence or willful misconduct.
Without limitation of the generality of the foregoing, the Agent (1) may treat the payee of any
Note as the holder thereof until the Agent receives written notice of the assignment or transfer
thereof signed by such payee and in form satisfactory to the Agent; (2) may consult with legal
counsel, independent public accountants and other experts selected by it and shall not be liable
for any action taken or omitted to be taken in good faith by it in accordance with the advice of
such counsel, accountants, or experts; (3) makes no warranty or representation to any Bank and
shall not be responsible to any Bank for any statements, warranties, or representations made in or
in connection with this Agreement; (4) shall not have any duty to ascertain or to inquire as to the
performance or observance of any of the terms, covenants, or conditions of this Agreement on the
part of the Borrower, or to inspect the property (including the books and records) of the Borrower;
(5) shall not be responsible to any Bank for the due execution, legality, validity, enforceability,
genuineness, perfection, sufficiency, or value of this Agreement or any other instrument or
document furnished pursuant thereto; and (6) shall incur no liability under or in respect of this
Agreement by acting upon any notice, consent, certificate, or other instrument or writing (which
may be sent by telegram, telex, or facsimile transmission) believed by it to be genuine and signed
or sent by the proper party or parties.

9.3. Rights of Agent as a Bank. With respect to its Commitment, the Loans made by it and the Note
issued to it, the Agent shall have the same rights and powers under this Agreement as any other
Bank and may exercise the same as though it were not the Agent; and the term “Bank” or “Banks”
shall, unless otherwise expressly indicated, include the Agent in its individual capacity. The
Agent and its Affiliates may accept deposits from, lend money to, act as trustee under indentures
of, and generally engage in any kind of business with, the Borrower, any of its Subsidiaries and
any Person who may do business with or own securities of the Borrower or any Subsidiary, all as if
the Agent were not the Agent and without any duty to account therefor to the Banks.

9.4. Independent Credit Decisions. Each Bank acknowledges that it has, independently and without
reliance upon the Agent or any other Bank and based on such documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each
Bank also acknowledges that it will, independently and without reliance upon the Agent or any other
Bank and based on such documents and information as it shall deem appropriate at the time, continue
to make its own credit decisions in taking or not taking action under this Agreement. Except for
notices, reports and other documents and information expressly required to be furnished to the
Agent by the Borrower or Guarantor hereunder or under any other Loan Document (each of which Agent
shall promptly upon receipt provide to each Bank), the Agent shall have no duty or responsibility
to provide any Bank with any credit or other information concerning the affairs, financial
condition or business of the Borrower or any of its Subsidiaries (or any of their Affiliates) which
may come into the possession of the Agent or any of its Affiliates.

9.5. Indemnification. The Banks agree to indemnify the Agent (to the extent not reimbursed by the
Borrower), ratably according to the respective amounts of their Commitments, from and against any
and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or
asserted against the Agent in any way relating to or arising out of this Agreement or any action
taken or omitted by the Agent under this Agreement, provided that no Bank shall be liable for any
portion of any of the foregoing resulting from the Agent’s gross negligence or willful misconduct.
Without limitation of the foregoing, each Bank agrees to reimburse the Agent (to the extent not
reimbursed by the Borrower) promptly upon demand for its Pro Rata Share of any out-of-pocket
expenses (including counsel fees) incurred by the Agent in connection with the preparation,
administration, or enforcement of, or legal advice in respect of rights or responsibilities under,
this Agreement.

9.6. Successor Agent. The Agent may resign at any time by giving at least sixty (60) days’ prior
written notice thereof to the Banks and the Borrower and may be removed at any time with cause, but
not without cause, by the Majority Banks. Upon any such resignation or removal, the Majority Banks
shall have the right to appoint a successor Agent. If no successor Agent shall have been so
appointed by the Majority Banks, and shall have accepted such appointment, within forty-five (45)
days after the retiring Agent’s giving of notice of resignation or the Majority Banks’ removal of
the retiring Agent, then the retiring Agent may, on behalf of the Banks, appoint a successor Agent,
which shall be a commercial bank organized under the laws of the United States of America or of any
State thereof and having a combined capital and surplus of at least Two Hundred Fifty Million
Dollars ($250,000,000.00). Upon the acceptance of any appointment as Agent hereunder by a
successor Agent, such successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and obligations under this Agreement. After any retiring Agent’s
resignation or removal hereunder as Agent, the provisions of this Section 9 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent under this
Agreement.

Sharing of Payments, Etc. If any Bank shall obtain any payment (whether voluntary, involuntary,
through the exercise of any right of setoff, or otherwise) on account of the Note held by it in
excess of its Pro Rata Share of payments on account of the Notes obtained by all the Banks, such
Bank shall purchase from the other Banks such participations in the Notes held by them as shall be
necessary to cause such purchasing Bank to share the excess payment ratably with each of the other
Banks, provided, however, that if all or any portion of such excess payment is thereafter recovered
from such purchasing Bank, such purchase from each Bank shall be rescinded and each Bank shall
repay to the purchasing Bank the purchase price to the extent of such recovery together with an
amount equal to such Bank’s Pro Rata Share (according to the proportion of (1) the amount of such
Bank’s required repayment to (2) the total amount so recovered from the purchasing Bank) of any
interest or other amount paid or payable by the purchasing Bank in respect of the total amount so
recovered. The Borrower agrees that any Bank so purchasing a participation from another Bank
pursuant to this Section 9.7 may, to the fullest extent permitted by law, exercise all its rights
of payment (including the right of setoff) with respect to such participation as fully as if such
Bank were the direct creditor of the Borrower in the amount of such participation.

10. ASSIGNMENTS and PARTICIPATIONS

10.1 Successors and Assigns. The terms and provisions of the Loan Documents shall be binding upon
and inure to the benefit of the Borrower and the Banks and their respective successors and assigns
permitted hereby, except that (i) the Borrower shall not have the right to assign its rights or
obligations under the Loan Documents without the prior written consent of each Bank, (ii) any
assignment by any Bank must be made in compliance with Section 10.3, and (iii) any transfer by
Participation must be made in compliance with Section 10.2. Any attempted assignment or transfer
by any party not made in compliance with this Section 10.1 shall be null and void, unless such
attempted assignment or transfer is treated as a participation in accordance with Section 10.3.2.
The parties to this Agreement acknowledge that clause (ii) of this Section 10.1 relates only to
absolute assignments and this Section 10.1 does not prohibit assignments creating security
interests, including, without limitation, (x) any pledge or assignment by any Bank of all or any
portion of its rights under this Agreement and any Note to a Federal Reserve Bank or (y) in the
case of a Bank which is a Fund, any pledge or assignment of all or any portion of its rights under
this Agreement and any Note to its trustee in support of its obligations to its trustee; provided,
however, that no such pledge or assignment creating a security interest shall release the
transferor Bank from its obligations hereunder unless and until the parties thereto have complied
with the provisions of Section 10.3. The Agent may treat the Person which made any Loan or which
holds any Note as the owner thereof for all purposes hereof unless and until such Person complies
with Section 10.3; provided, however, that the Agent may in its discretion (but shall not be
required to) follow instructions from the Person which made any Loan or which holds any Note to
direct payments relating to such Loan or Note to another Person. Any assignee of the rights to any
Loan or any Note agrees by acceptance of such assignment to be bound by all the terms and
provisions of the Loan Documents. Any request, authority or consent of any Person, who at the time
of making such request or giving such authority or consent is the owner of the rights to any Loan
(whether or not a Note has been issued in evidence thereof), shall be conclusive and binding on any
subsequent holder or assignee of the rights to such Loan.

10.2 Participations.

10.2.1 Permitted Participants; Effect. Any Bank may, without the consent of Borrower but with
the consent of Agent, at any time sell to one or more banks or other entities (“Participants”)
participating interests in any Loan owing to such Bank, any Note held by such Bank, any Commitment
of such Bank or any other interest of such Bank under the Loan Documents. In the event of any such
sale by a Bank of participating interests to a Participant, such Bank’s obligations under the Loan
Documents shall remain unchanged, such Bank shall remain solely responsible to the other parties
hereto for the performance of such obligations, such Bank shall remain the owner of its Loans and
the holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents,
all amounts payable by the Borrower under this Agreement shall be determined as if such Bank had
not sold such participating interests, and the Borrower and the Agent shall continue to deal solely
and directly with such Bank in connection with such Bank’s rights and obligations under the Loan
Documents.

10.2.2 Voting Rights. Each Bank shall retain the sole right to approve, without the consent
of any Participant, any amendment, modification or waiver of any provision of the Loan Documents
other than any amendment, modification or waiver with respect to any Loan or Commitment in which
such Participant has an interest which would require consent of all of the Banks.

10.2.3 Benefit of Certain Provisions. The Borrower agrees that each Participant shall be
deemed to have the right of setoff provided in Section 8.1.17 in respect of its participating
interest in amounts owing under the Loan Documents to the same extent as if the amount of its
participating interest were owing directly to it as a Bank under the Loan Documents, provided that
each Bank shall retain the right of setoff provided in Section 8.1.17 with respect to the amount of
participating interests sold to each Participant. The Banks agree to share with each Participant,
and each Participant, by exercising the right of setoff provided in Section 8.1.17, agrees to share
with each Bank, any amount received pursuant to the exercise of its right of setoff, such amounts
to be shared in accordance with Section 8.1.17as if each Participant were a Bank. The Borrower
further agrees that each Participant shall be entitled to the benefits of Sections 2.17, 2.18 and
2.19 to the same extent as if it were a Bank and had acquired its interest by assignment pursuant
to Section 10.3, provided that a Participant shall not be entitled to receive any greater payment
under Sections 2.17, 2.18 and 2.19 than the Bank who sold the participating interest to such
Participant would have received had it retained such interest for its own account, unless the sale
of such interest to such Participant is made with the prior written consent of the Borrower.

10.3 Assignments.

10.3.1 Permitted Assignments. Any Bank may at any time assign to one or more banks or other
entities (“Purchasers”) all or any part of its rights and obligations under the Loan Documents.
Such assignment shall be substantially in form and content substantially as set forth on
Schedule “10.3.1" hereto or in such other form as may be agreed to by the parties thereto.
Each such assignment with respect to a Purchaser which is not a Bank or an Affiliate of a Bank
shall either be in an amount equal to the entire applicable Commitment and Loans of the assigning
Bank or (unless each of the Borrower and the Agent otherwise consents) be in an aggregate amount
not less than $5,000,000. The amount of the assignment shall be based on the Commitment or
outstanding Loans (if the Commitment has been terminated) subject to the assignment, determined as
of the date of such assignment or as of the “Trade Date,” if the “Trade Date” is specified in the
assignment.

10.3.2. Consents. The consent of the Borrower shall be required prior to an assignment
becoming effective unless the Purchaser is a Bank, an Affiliate of a Bank, provided that the
consent of the Borrower shall not be required if a Default has occurred and is continuing. The
consent of the Agent shall be required prior to an assignment becoming effective unless the
Purchaser is an Affiliate of a Bank. Any consent required under this Section 10.3.2 shall not be
unreasonably withheld or delayed.

10.3.3. Effect; Effective Date. Upon (i) delivery to the Agent of an assignment, together
with any consents required by Sections 10.3.1 and 10.3.2, and (ii) payment of $     fee to the
Agent for processing such assignment (unless such fee is waived by the Agent), such assignment
shall become effective on the effective date specified in such assignment. The assignment shall
contain a representation by the Purchaser to the effect that none of the consideration used to make
the purchase of the Commitment and Loans under the applicable assignment agreement constitutes
“plan assets” as defined under ERISA and that the rights and interests of the Purchaser in and
under the Loan Documents will not be “plan assets” under ERISA. On and after the effective date of
such assignment, such Purchaser shall for all purposes be a Bank party to this Agreement and any
other Loan Document executed by or on behalf of the Banks and shall have all the rights and
obligations of a Bank under the Loan Documents, to the same extent as if it were an original party
thereto, and the transferor Bank shall be released with respect to the Commitment and Loans
assigned to such Purchaser without any further consent or action by the Borrower, the Banks or the
Agent. In the case of an assignment covering all of the assigning Bank’s rights and obligations
under this Agreement, such Bank shall cease to be a Bank hereunder but shall continue to be
entitled to the benefits of, and subject to, those provisions of this Agreement and the other Loan
Documents which survive payment of the Obligations and termination of the applicable agreement.
Any assignment or transfer by a Bank of rights or obligations under this Agreement that does not
comply with this Section 10.3 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 10.2. Upon the
consummation of any assignment to a Purchaser pursuant to this Section 10.3.3, the transferor Bank,
the Agent and the Borrower shall, if the transferor Bank or the Purchaser desires that its Loans be
evidenced by Notes, make appropriate arrangements so that new Notes or, as appropriate, replacement
Notes are issued to such transferor Bank and new Notes or, as appropriate, replacement Notes, are
issued to such Purchaser, in each case in principal amounts reflecting their respective
Commitments, as adjusted pursuant to such assignment.

10.3.4. Register. The Agent, acting solely for this purpose as an agent of the Borrower,
shall maintain at one of its offices in Tulsa, Oklahoma a copy of each Assignment and Assumption
delivered to it and a register for the recordation 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 (the “Register”). The entries in the Register shall be conclusive, and the
Borrower, the Agent and the Banks may treat each Person whose name is recorded in the Register
pursuant to the terms hereof as a Bank hereunder for all purposes of this Agreement,
notwithstanding notice to the contrary. The 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.

10.4. Dissemination of Information. The Borrower authorizes each Bank to disclose to any
Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by
operation of law (each a “Transferee”) and any prospective Transferee any and all information in
such Bank’s possession concerning the creditworthiness of the Borrower and its Subsidiaries.

11. MISCELLANEOUS

11.1 Amendments, Etc. No amendment, modification, termination, or waiver of any provision of any
Loan Document to which the Borrower is a party, nor consent to any departure by the Borrower from
any Loan Document to which it is a party, shall in any event be effective unless the same shall be
in writing and signed by the Majority Banks, and then such waiver or consent shall be effective
only in the specific instance and for the specific purpose for which given, provided, however, that
no amendment, waiver or consent shall, unless in writing and signed by all the Banks, do any of the
following: (1) waive any of the conditions precedent specified in Section 3; (2) increase the
Commitments of the Banks or subject the Banks to any additional obligations; (3) reduce the
principal of, or interest on, the Notes or any fees hereunder; (4) postpone any date fixed for any
payment of principal of, or interest on, the Notes or any fees hereunder; (5) release any of the
Guarantors; (6) change the percentage of the Commitments or of the aggregate unpaid principal
amount of the Notes or the number of Banks which shall be required for the Banks or any of them to
take action hereunder; or amend, modify or waive any provision of this Section 10.1, and provided
further that no amendment, waiver, or consent shall, unless in writing and signed by the Agent in
addition to the Banks required above to take such action, affect the rights or duties of the Agent
under any of the Loan Documents.

11.2 Notices, Etc. All notices and other communications provided for under this Agreement and
under the other Loan Documents to which the Borrower is a party shall be in writing (including

AGENT HAS AUTHORITY TO WAIVE, CONDITION, OR MODIFY THIS PROVISION.

11.13 USA Patriot Act Notification. IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A
NEW ACCOUNT. To help the government fight the funding of terrorism and money laundering
activities, Federal law requires all financial institutions to obtain, verify, and record
information that identifies each person or entity that opens an account, including any deposit
account, treasury management account, loan, other extension of credit, or other financial services
product. What this means for Borrower: When Borrower opens an account, if Borrower is an
individual, Bank will ask for Borrower’s name, taxpayer identification number, residential address,
date of birth, and other information that will allow Bank to identify Borrower, and, if Borrower is
not an individual, Bank will ask for Borrower’s name, taxpayer identification number, business
address, and other information that will allow Bank to identify Borrower. Bank may also ask, if
Borrower is an individual, to see Borrower’s driver’s license or other identifying documents, and,
if Borrower is not an individual, to see Borrower’s legal organizational documents or other
identifying documents.

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

of the Guaranty dated September 20, 2002, executed and delivered by the Guarantor.

AGREEMENT

For and in consideration of the Recitals and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged by Guarantor, and in order to induce the
Banks to extend the Loan to Borrower, Guarantor hereby agrees with the Banks as follows:

Section 1. Guarantee. Guarantor, jointly and severally with the other guarantor(s)
of the obligations of Borrower to the Banks, hereby absolutely and unconditionally guarantees to
the Banks and their successors and assigns the due and punctual payment of all liabilities and the
performance of all obligations of Borrower to the Banks under the Notes, the Restated Credit
Agreement, any Rate Management Obligations, any reimbursement agreement relating to a Letter of
Credit, and any other document or instrument executed by Borrower in connection with the Loan,
primary or secondary (whether by way of endorsement or otherwise), whether now existing or
hereafter arising, whether arising out of contracts, torts or otherwise, whether created directly
with the Banks or acquired by the Banks through assignment, endorsement or otherwise; whether
matured or unmatured; whether absolute or contingent; whether joint or several; as and when the
same become due and payable (whether by acceleration or otherwise), in accordance with the terms of
any such instruments, accounts receivable and other security agreements, contracts, drafts, leases
or chattel paper, evidencing any such indebtedness, obligations or liabilities, including all
renewals, extensions or modifications thereof (all liabilities and obligations of Borrower to the
Banks, including all of the foregoing, being hereinafter collectively referred to as the
“Obligations”).

Further, whether or not suit is brought by the Agent or the Banks against Borrower or any
other guarantor to acquire possession of collateral or to enforce collection of any unpaid balances
hereunder, Guarantor hereby expressly agrees to pay all reasonable legal expenses and attorneys’
fees (including legal assistants’ fees) actually incurred by the Agent and the Banks.

Section 2. Operation of Guaranty. This is a guaranty of payment and not of
collection, and Guarantor expressly waives any right to require that any action be brought against
Borrower or any other guarantor of the Obligations or with respect to any security therefor. If
Borrower shall default in payment or performance of any of the Obligations when due, Guarantor,
upon written demand by Agent, without notice other than such demand and without the necessity of
further action by the Agent or the Banks, will promptly and fully make such payments and indemnify
the Banks and their officers, directors, employees, representatives, counsel and agents from and
against any and all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind whatsoever which may at any time (including
without limitation at any time following payment of the Loan and Notes) be imposed on, incurred by
or asserted against any such person in any way relating to or arising out of Borrower’s failure to
pay its indebtedness to the Banks. All payments by Guarantor shall be made in any coin or currency
of the United States of America which on the respective dates of payment thereof is legal tender
for the payment of public and private debts and which is immediately available to Agent, for the
benefit of the Banks, at its principal office in Tulsa, Oklahoma (or such other place as Agent may
designate in writing). Each default in payment or performance of the Obligations shall give rise
to a separate cause of action hereunder, and separate suits may be brought hereunder as each cause
of action arises.

Section 3. Obligations of Guarantor Absolute and Unconditional. The obligations of
Guarantor hereunder shall be absolute and unconditional, shall remain in full force and effect
until all of the Obligations shall have been fully and indefeasibly paid and performed and shall
not be impaired, modified, released or limited by any occurrence or condition whatsoever (other
than full, final and indefeasible payment and performance of all of the Obligations), including
without limitation (a) any compromise, settlement, release, waiver, renewal, extension, indulgence
or modification of or change in any of the Obligations, (b) any impairment, modification, release
or limitation of the liability of Borrower, or any security for the Obligations, or any remedy for
the enforcement thereof, resulting from the operation of any present or future provision of the U.
S. Bankruptcy Code, as amended, or other statute or from the decision of any court, (c) the
assertion or exercise by the Agent or the Banks of any other rights or remedies with respect to the
Obligations or any delay in exercising or failure to assert or exercise any such rights or
remedies, (d) the assignment or mortgaging or the purported assignment or mortgaging of any
property as security for the Obligations, or the release of any such security, (e) any limitation
of Borrower’s liability for the payment or performance of the Obligations imposed by applicable
law, (f) the extension of the time for payment or performance of any of the Obligations or the
extension or the renewal of any thereof, (g) the modification or amendment (whether material or
otherwise) of the Notes, (h) the voluntary or involuntary liquidation, dissolution, sale or other
disposition of all or substantially all of the assets, marshaling of assets and liabilities,
receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization,
arrangement, composition or readjustment of, or other similar proceeding affecting Borrower,
Guarantor, any other guarantor of the Obligations, or any of their affiliates, or any of their
assets, or the disaffirmance of this Guaranty in any such proceeding, (i) the release, substitution
or replacement of any security for the Obligations or any other guaranty thereof, (j) acceptance by
the Agent or the Banks of any payment or performance which is defeasible, void or voidable, as a
preference or otherwise, (k) the unenforceability, invalidity or voidability of the Notes, or (1)
any other occurrence, event or circumstance which might, but for this provision, constitute a legal
or equitable discharge or defense of a guarantor or surety.

Section 4. Waiver of Notice, etc. Guarantor unconditionally waives: (a) notice of any
of the matters referred to in Section 2 hereof except written demand for payment hereunder; (b) any
demand, proof or notice of nonpayment of the principal of or interest on the Notes or of any other
default in the due and timely payment and performance of any of the Obligations; (c) with respect
to the Notes, presentment for payment, notice of dishonor, protest and notice of protest; (d) all
other notices to which Guarantor would otherwise be entitled; (e) the benefits of all provisions of
law for a stay or delay of execution or any other remedy against Guarantor until a proceeding be
commenced or a judgment be obtained against Borrower and be returned unsatisfied; and (f) to the
fullest extent permitted by applicable law, all other rights and defenses of a guarantor or surety
including, without limitation, those set forth under Title 15 Okla. Stat. §§ 334, 337, 338 and
344, and Title 12 Okla. Stat. § 686.

Section 5. No Right of Setoff. No act of commission or omission of any kind or at any
time upon the part of Borrower, the Agent or the Banks in respect of any matter whatsoever shall in
any way affect or impair the rights of the Banks to enforce any right, power or benefit of the
Banks under this Guaranty, and no setoff, claim, reduction or diminution of any obligation or any
defense of any kind or nature which Guarantor has or may have against Borrower, the Agent or the
Banks shall be available to Guarantor against the Agent or the Banks in any suit or action brought
by the Agent or the Banks to enforce any right, power or benefit under this Guaranty.

If any process is issued or ordered to be served upon the Agent or the Banks, seeking to seize
Borrower’s or Guarantor’s rights or interests in any bank accounts maintained with the Banks, the
balances in any such accounts shall immediately be deemed to have been and shall be set off against
any and all Obligations or all obligations and liabilities of the Guarantor, as of the time of the
issuance of any such writ or process, whether or not Borrower, Guarantor, the Agent or the Banks
shall then have been served therewith.

Section 6. Subordination. All obligations, indebtedness and liabilities, present and
future, of Borrower to Guarantor are hereby subordinated to the Obligations. Guarantor agrees
that, from and after the occurrence and during the continuance of an Event of Default hereunder,
the Agent, on behalf of the Banks, shall be entitled to receive full payment of all Obligations
before payment of any obligations, liabilities or indebtedness of Borrower to Guarantor and, to
that effect, agrees:

(a) To receive and hold all amounts paid to Guarantor by or on behalf of Borrower in trust
for the Banks and immediately to pay to Agent such amounts for application to the
obligations, and

(b) Upon any liquidation or distribution of the assets of Borrower, to assign to the Banks
upon their request all claims on account of all obligations, indebtedness and liabilities of
Borrower to Guarantor, to the end that Agent, on behalf of the Banks, shall receive all
dividends and payments on such obligations, indebtedness and liabilities until payment in
full of all Obligations. This Guaranty shall constitute such an assignment in the event
Guarantor shall fail or refuse to execute and deliver such other or further assignment of
such claims as the Banks may request.

Notwithstanding the foregoing provisions of this Section, Guarantor shall be entitled to
receive, and shall not be required to hold for or to pay to Agent, payments from Borrower due and
made prior to the occurrence of an Event of Default hereunder.

Section 7. Extinguishment and Waiver of Subrogation and Contribution.

(a) If any payment of an Obligation shall at any time be repaid by the recipient thereof in
compliance with an order of a court having jurisdiction over any bankruptcy or insolvency
proceedings relating to Borrower, the amount so repaid shall be deemed not to have been paid
and to be outstanding, and the obligation of Guarantor hereunder to satisfy such Obligation
shall remain in full force and effect.

(b) Guarantor hereby irrevocably waives any claims or other rights which it now or hereafter
acquires against Borrower that arise from the existence or performance of Guarantor’s
obligations under this Guaranty including, without limitation, any right of subrogation,
reimbursement, exoneration, contribution, indemnification, any right to participate in any
claim or remedy of the Banks against Borrower or any security or collateral which the Banks
now have or hereafter acquire, whether or not such claim, remedy or right arises in equity
or under contract, statute or common law, by any payment made hereunder or otherwise
including, without limitation, the right to take or receive from Borrower, directly or
indirectly, in cash or other property or by setoff or in any other manner, payment or
security on account of such claim or other rights. Guarantor hereby irrevocably agrees that
it will not, until the Obligations are paid in full, exercise any rights which it may
acquire by way of contribution under this Guaranty, by any payment made hereunder or
otherwise including, without limitation, the right to take or receive from any other
guarantor, directly or indirectly, in cash or other property or by setoff or in any other
manner, payment or security on account of such contribution rights. If any amount shall be
paid to Guarantor in violation of the preceding sentences and the Obligations shall not have
been paid in full, such amount shall be deemed to have been paid to Guarantor for the
benefit of, and held in trust for the benefit of, the Banks and shall forthwith be paid to
Agent, on behalf of the Banks, to be credited and applied upon the Obligations, whether
matured or unmatured.

Section 8. Due Diligence. Guarantor acknowledges and represents that it has relied
upon its own due diligence in making its own independent appraisal of Borrower and its business,
affairs and financial condition, and will continue to be responsible for making its own independent
appraisal of such matters, and has not relied upon and will not hereafter rely upon the Agent or
the Banks for information for such appraisal or other assessment or review and, further, will not
rely upon any such information which may now or hereafter be prepared by or for the Agent or the
Banks for any appraisals regarding Borrower.

Section 9. Events of Default. The occurrence of any one or more of the following
events shall constitute an “Event of Default”:

(a) An Event of Default as defined in the Restated Credit Agreement; or

(b) Appointment of a receiver of any part of the property of Borrower or Guarantor, or
insolvency, business failure, assignment for the benefit of creditors by, or the
commencement of any proceeding under any state or Federal bankruptcy or insolvency laws by
or against, Borrower or Guarantor; or

(c) Any warranty, representation or statement made or furnished to the Agent or the Banks by
or on behalf of Borrower or Guarantor, in connection with this Guaranty or to induce the
Banks to extend credit or otherwise deal with either Borrower or Guarantor proves to have
been false in any material respect when made or furnished; or

(d) Any monetary judgment, assessment, attachment or lien shall be filed against Borrower or
Guarantor or against any of their property and shall remain unpaid or unstayed for a period
in excess of thirty (30) days.

Section 10. Remedies. Should any one or more of the Events of Default defined in
Section 9 occur and be continuing, the Banks may, at their option, enforce against Guarantor its
liabilities hereunder and exercise such other rights and remedies as may be available to the Banks
hereunder, under the Notes and otherwise.

Section 11. Remedies Cumulative. No right or remedy herein conferred upon the Agent
or the Banks is intended to be exclusive of any other right or remedy contained herein or in the
Notes or in any other instrument or document delivered pursuant to or in connection with the Notes,
and every such right or remedy contained herein and therein or now or hereafter existing at law or
in equity, or by statute or otherwise, shall be cumulative. The Banks may pursue, or refrain from
pursuing, any remedy available to them at such times and in such order as they in their sole
discretion shall determine, and the Banks’ election as to such remedies shall not impair any
remedies against Guarantor not then exercised.

Section 12. Modification and Waiver. No modification or waiver of any provision of
this Guaranty or of any document or instrument delivered pursuant hereto and no consent by the
Agent or the Banks to any departure therefrom shall be effective unless such modification or waiver
shall be in writing and signed by a duly authorized officer of Agent, on behalf of the Banks, and
the same shall then be effective only for the period and on the conditions and for the specific
instances and purposes specified in such writing. No notice to or demand on Guarantor in any case
shall entitle Guarantor to any other or further notice or demand in similar or other circumstances.

Section 13. Fees and Expenses. Guarantor shall reimburse Agent, or cause Agent to be
reimbursed, for all out of pocket costs and expenses incurred by Agent and the Banks with respect
to the documentation or administration of this Guaranty or enforcing the terms hereof, including
the reasonable fees and expenses of the Agent’s and the Banks’ attorneys.

Section 14. Application of Proceeds. All proceeds of any security or any enforcement
action received by the Agent or the Banks with respect to the Obligations may be applied by the
Agent to the Obligations in such order as the Agent and the Banks in their sole discretion may
elect.

Section 15. Governing Law. This Guaranty shall be construed in accordance with and
governed by the laws of the State of Oklahoma, without giving effect to the principles of the
conflict of laws.

Section 16. Service of Process. Guarantor hereby irrevocably consents and agrees that
any legal action, suit or proceeding arising out of or in any way in connection with this Guaranty
may be instituted or brought in all federal and state courts located in the State of Oklahoma, as
Agent may elect and, by the execution and delivery of this Guaranty, Guarantor hereby irrevocably
and unconditionally accepts and submits to the exclusive jurisdiction of any such courts, and to
all proceedings in such courts. Guarantor also consents that service of process in any such action
or proceeding may be made upon Guarantor by mailing a copy of the summons and the complaint to
Guarantor by registered mail, return receipt requested, at the address designated for notices to
Guarantor under Section 19 of this Guaranty. Nothing in this Guaranty or elsewhere shall affect
the Agent’s or the Banks’ right to serve process in any other manner permitted by law or limit the
right of the Agent or the Banks to bring actions, suits or proceedings in the courts of any other
jurisdiction.

Section 17. Waiver of Jury Trial. GUARANTOR HEREBY WAIVES ANY RIGHT TO A TRIAL BY
JURY IN CONNECTION WITH ANY LITIGATION IN ANY COURT WITH RESPECT TO, IN CONNECTION WITH OR ARISING
OUT OF THIS GUARANTY, OR THE VALIDITY, PROTECTION, INTERPRETATION, COLLECTION OR ENFORCEMENT OF
THIS GUARANTY, OR ANY OTHER CLAIM OR DISPUTE, HOWSOEVER ARISING, BETWEEN GUARANTOR AND THE AGENT OR
