	2.	 	LENDING COMMITMENT

2.1. Revolving Credit Loans. 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”) to the Borrower from time to time during the period from the Effective
Date up to but not including the Termination Date, in an aggregate principal amount not to exceed
at any time such Bank’s Commitment; provided, however, that (i) after giving effect
to the making of any Revolving Credit Loan, the Aggregate Outstanding Credit Exposure, until the
first calculation of the Borrowing Base, shall not exceed the Revolving Credit Commitment, and from
and after the first calculation of the Borrowing Base shall not exceed the lesser of (A) the
Revolving Credit Commitment, or (B) the Available Borrowing Base in effect on such date; and
(ii) as to any Bank, the sum of its Pro Rata Share of the aggregate outstanding amount of the
Revolving Credit Loans, plus such Bank’s Pro Rata Share of the outstanding amount of all
L/C Obligations, plus such Bank’s Pro Rata Share of the outstanding amount of all Swing
Line Loans, until the first calculation of the Borrowing Base, shall not exceed such Bank’s
Commitment, and from and after the first calculation of the Borrowing Base, shall not exceed the
lesser of (A) such Bank’s Commitment or (B) such Bank’s Pro Rata Share of the Available Borrowing
Base. 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). Any request for a Revolving Credit Loan for a lesser amount shall be made
as a Swing Line Loan. Pursuant to the terms and conditions set forth herein, the Revolving Credit
Loans may be outstanding as Base Rate Loans or LIBOR Loans. Each type of Revolving Credit Loan
shall be made and maintained by each Bank at its Lending Office for such type of Loan. The failure
of any Bank to advance its Pro Rata Share of any requested Revolving Credit 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. The L/C Issuer hereby agrees, 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 Effective Date 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 L/C Obligations shall not exceed $100,000,000, and
the aggregate principal amount of all Revolving Credit Loans and Swing Line Loans and all
outstanding L/C 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. Subject to Section 2.2.1, the Borrower shall give the L/C Issuer 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 L/C Issuer of any Letter of Credit
shall, in addition to the conditions precedent set forth in Section 3 (the satisfaction of which
the L/C Issuer shall have no duty to ascertain), be subject to the conditions precedent that such
Letter of Credit shall be satisfactory to the L/C Issuer 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 L/C Issuer 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. Notwithstanding anything to the contrary contained herein or in any Letter of Credit
Application, the L/C Issuer shall not be under any obligation to issue any requested Letter of
Credit if:

(a) any order, judgment or decree of any governmental authority or arbitrator shall by
its terms purport to enjoin or restrain the L/C Issuer from issuing such Letter of Credit,
or any legal requirement applicable to the L/C Issuer or any request or directive (whether
or not having the force of law) from any Governmental Authority with jurisdiction over the
L/C Issuer shall prohibit, or request that the L/C Issuer refrain from, the issuance of
letters of credit generally or such Letter of Credit in particular or shall impose upon the
L/C Issuer with respect to such Letter of Credit any restriction, reserve or capital
requirement (for which the L/C Issuer is not otherwise compensated hereunder) not in effect
on the Effective Date, or shall impose upon the L/C Issuer any unreimbursed loss, cost or
expense which was not applicable on the Effective Date and which the L/C Issuer in good
faith deems material to it;

(b) except as otherwise agreed by the L/C Issuer, such Letter of Credit is to be
denominated in a currency other than Dollars;

(c) a default of any Bank’s obligations to fund under Section 2.2.7 exists or any Bank
is at such time a Defaulting Bank hereunder, unless the L/C Issuer has entered into
satisfactory arrangements with the Borrower or such Bank to eliminate the L/C Issuer’s risk
with respect to such Bank; or

(d) the beneficiary of a Letter of Credit which is requested to be issued does not
accept the proposed Letter of Credit.

2.2.4. Upon the issuance of each Letter of Credit, the Borrower shall (i) pay a fee to the
Administrative 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, and (ii) pay to the L/C Issuer
for its own account an issuance fee equal to 0.125% of the face amount of such Letter of Credit.

2.2.5. In the event that the beneficiary of any Letter of Credit requested to be issued
hereunder will not accept a Letter of Credit issued by the L/C Issuer, the L/C Issuer will use
commercially reasonable efforts to arrange for another Bank to issue the requested Letter of
Credit. The Borrower shall pay any issuance or fronting fees charged by the issuing Bank, and the
Borrower acknowledges that such fees may be higher than the issuance fee provided for in Section
2.2.4.

2.2.6. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing
the amount thereof) and without any further action on the part of the L/C Issuer or the Bank, the
L/C Issuer hereby grants to each Bank, and each Bank hereby acquires from the L/C Issuer, a
participation in such Letter of Credit equal to such Bank’s Pro Rata Share of the aggregate amount
available to be drawn under such Letter of Credit. In consideration and in furtherance of the
foregoing, each Bank hereby absolutely and unconditionally agrees to pay to the L/C Issuer such
Bank’s Pro Rata Share of each payment made by the L/C Issuer upon any drawing and not reimbursed by
the Borrower on the Letter of Credit Payment Date as provided in Section 2.2.7, or of any
reimbursement payment required to be refunded to the Borrower for any reason. Each Bank
acknowledges and agrees that its obligation to acquire participations pursuant to this Section
2.2.6 in respect of Letters of Credit is absolute and unconditional and shall not be affected by
any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit
or the occurrence and continuance of any Default or reduction or termination of the Revolving
Credit Commitment, and that each such payment shall be made without any offset, abatement,
withholding or reduction whatsoever.

2.2.7. Upon receipt from the beneficiary of any demand for payment under any Letter of Credit,
the L/C Issuer shall promptly notify the Borrower and the Administrative Agent as to the amount to
be paid by the L/C Issuer as a result of such demand and the proposed payment date (each a “Letter
of Credit Payment Date”). The Borrower and any other applicable account party shall be irrevocably
and unconditionally obligated to reimburse the L/C Issuer on or by the applicable Letter of Credit
Payment Date for any amounts to be paid by the L/C Issuer upon any drawing under any Letter of
Credit, without presentment, demand, protest or other formalities of any kind. All such amounts
paid by the L/C Issuer and remaining unpaid by the 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.

2.2.8. If the Borrower fails to make such payment when due, the Administrative Agent shall
notify each Bank of such drawing, the payment amount then due from the Borrower in respect thereof
and such Bank’s Pro Rata Share thereof. Promptly following receipt of such notice, each Bank shall
pay to the Administrative Agent (for the account of the L/C Issuer) its Pro Rata Share of the
payment then due from the Borrower, in the same manner as provided in Section 2.1 with respect to
Revolving Credit Loans made by such Bank, and the amounts so paid to the Administrative Agent shall
be deemed Revolving Credit Loans for purposes of this Agreement.

2.2.9. 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 L/C Issuer 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 L/C Issuer of
issuing or maintaining any Letter of Credit, or reduce any amount receivable hereunder by the L/C
Issuer in respect of any Letter of Credit (which increase in cost, or reduction in amount
receivable, shall be the result of the L/C Issuer’s reasonable allocation of the aggregate of such
increases or reductions resulting from such event), then, upon demand by the L/C Issuer, the
Borrower agrees to pay to the L/C Issuer, from time to time as specified by the L/C Issuer, such
additional amounts as shall be sufficient to compensate the L/C Issuer for such increased costs or
reductions in amounts received by the L/C Issuer. A certificate of the L/C Issuer submitted by the
L/C Issuer to the Borrower shall be conclusive as to the amount thereof in the absence of manifest
error.

2.2.10. 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 L/C Issuer or any beneficiary of a Letter of Credit. The
Borrower and the applicable account parties further agree with the L/C Issuer 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
the 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 the 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 responsibility of the L/C Issuer to the 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. The L/C Issuer 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. The Borrower and any other applicable account parties agree that any
action taken or omitted by the L/C Issuer 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 L/C Issuer under any liability to any
of them.

2.2.11. The L/C Issuer 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 L/C Issuer.

2.2.12. The Borrower hereby agrees to indemnify and hold harmless the L/C Issuer, and its
respective directors, officers and employees from and against any and all claims and damages,
losses, liabilities, costs or expenses which the L/C Issuer may incur (or which may be claimed
against the L/C Issuer 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 L/C Issuer may incur by reason of or on account of
the L/C Issuer 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 L/C Issuer, evidencing the appointment of such successor
beneficiary; provided that Borrower shall not be required to indemnify the L/C Issuer 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 L/C Issuer in determining whether a
request presented under any Letter of Credit complied with the terms of such Letter of Credit or
(ii) the L/C Issuer’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) the Borrower or any other applicable account parties, or their Affiliates, on the one
hand, and (ii) the L/C Issuer, on the other hand, are directly opposing parties and with respect to
which a final, non-appealable judgment has been rendered in favor of the Borrower or such other
applicable account party or their Affiliates by a court of competent jurisdiction. Nothing in this
Section 2.2.12 is intended to limit the obligations of Borrower under any other provision of this
Agreement.

2.2.13. The L/C Issuer may be replaced at any time by written agreement among the Borrower,
the Administrative Agent, the replaced L/C Issuer and the successor L/C Issuer. The Administrative
Agent shall notify the Banks of any such replacement of the L/C Issuer. At the time any such
replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account
of the replaced L/C Issuer pursuant to Section 2.2.4. From and after the effective date of any
such replacement, (i) the successor L/C Issuer shall have all the rights and obligations of the L/C
Issuer under this Agreement with respect to Letters of Credit to be issued thereafter and (ii)
references herein to the term “L/C Issuer” shall be deemed to refer to such successor or to any
previous L/C Issuer, or to such successor and all previous L/C Issuers, as the context shall
require. After the replacement of an L/C Issuer hereunder, the replaced L/C Issuer shall remain a
party hereto and shall continue to have all the rights and obligations of an L/C Issuer under this
Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not
be required to issue additional Letters of Credit.

2.3. Reduction of Revolving Credit Commitment.

2.3.1. The Borrower shall have the right, upon at least three (3) Business Days’ notice to the
Administrative Agent, to terminate in whole or reduce in part the unused portion of the Revolving
Credit Commitment, 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, Swing Line 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 Revolving Credit Commitment, once so reduced or terminated,
may not be reinstated.

2.3.2. Upon any prepayment by the Borrower of any principal portion of the Prudential Term
Notes during the Adjusted Covenant Period (but excluding any scheduled principal payments made in
accordance with the principal installment due dates set forth in the respective Prudential Term
Notes), the Revolving Credit Commitment shall be reduced by an amount equal to the amount of such
prepayment and the Borrower shall, simultaneously with such prepayment on the Prudential Term
Notes, prepay Revolving Credit Loans (or, if necessary, cash collateralize the outstanding Letters
of Credit) in an amount equal to the amount, if any, by which the Aggregate Outstanding Credit
Exposure exceeds the reduced amount of the Revolving Credit Commitment. Any such reduction in the
Revolving Credit Commitment shall reduce each Bank’s Commitment in the proportion that such Bank’s
Commitment bears to the Revolving Credit Commitment. The Revolving Credit Commitment, once so
reduced, may not be reinstated.

2.4. Notice and Manner of Borrowing. The Borrower shall give the Administrative Agent notice of any
Revolving Credit Loans under this Agreement prior to 12:00 noon on the day of each Base Rate 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, which notice shall be in form and content as
set forth on Exhibit C hereto (a “Borrowing Notice”). The Administrative Agent shall
promptly notify each Bank of its receipt of a Borrowing Notice. Not later than 1:00 p.m. on the
date of such Revolving Credit Loan, each Bank will make available to the Administrative Agent at
the Administrative Agent’s Principal Office in immediately available funds, such Bank’s Pro Rata
Share of such Revolving Credit Loan. After the Administrative 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 Administrative 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 Administrative Agent: Account styled Saia, Inc. Operating
Account, No. 209908769. All times shall be based on Central Time. All Borrowing Notices shall be
irrevocable and shall be given not later than 12:00 noon on the day which is not less than the
number of Business Days specified above for such Borrowing Notice.

2.5. Non-Receipt of Funds by Agent.

2.5.1. Unless the Administrative Agent shall have received notice from a Bank prior to the
date on which such Bank is to provide funds to the Administrative Agent for a Revolving Credit Loan
to be made by such Bank that such Bank will not make available to the Administrative Agent such
funds, the Administrative Agent may assume that such Bank has made such funds available to the
Administrative Agent on the date of such Revolving Credit Loan in accordance with Section 2.4 and
the Administrative 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 Administrative Agent, such
Bank agrees to repay to the Administrative 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 the Administrative Agent until the date such amount is repaid to the Administrative
Agent, at the Federal Funds Rate for the first three days and thereafter at the interest rate then
applicable to the Revolving Credit Loans. If such Bank shall repay to the Administrative Agent such
corresponding amount, such amount so repaid shall constitute such Bank’s Revolving Credit Loan for
purposes of this Agreement. If such Bank does not pay such corresponding amount forthwith upon the
Administrative Agent’s demand therefor, the Administrative Agent shall promptly notify the
Borrower, and the Borrower shall immediately pay such corresponding amount to the Administrative
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 Administrative Agent, at the rate of interest
applicable at the time to such proposed Revolving Credit Loan.

2.5.2. Unless the Administrative 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 Administrative Agent may assume that the Borrower has made such payment in
full to the Administrative Agent on such date and the Administrative 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 Administrative Agent, each Bank
shall repay to the Administrative 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 Administrative Agent, at the Federal Funds Rate
for the first three 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 Revolving Credit Loan into another type of Revolving Credit Loan or to renew all or
part of a Revolving Credit Loan by giving the Administrative Agent written notice by submitting to
the Administrative Agent an Interest Rate Election Notice, in form and content as set forth on
Exhibit D hereto, at least one (1) Business Day before conversion into a Base Rate 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 Revolving Credit 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 one-month, two-month, three-month or four-month durations; provided that (a) the
minimum principal amount of each Revolving Credit Loan outstanding after a renewal or conversion
shall be Two Hundred Thousand and No/100 Dollars ($200,000.00) in the case of Base Rate 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 Administrative Agent
shall promptly notify each Bank of each such notice. All conversions and renewals shall be made in
accordance with each Bank’s Pro Rata Share of the amount to be converted or renewed. 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 Administrative 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 Rate 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, the 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 Loans 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 Administrative 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 Administrative Agent shall request settlement (“Settlement”) with the Banks on a
weekly basis, or on a more frequent basis if so determined by the Administrative 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 Administrative Agent in
same day funds to such account of the Administrative Agent as the Administrative 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 Administrative 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 Administrative Agent by any Bank on the
Settlement Date applicable thereto, the Administrative 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 Administrative Agent, each other Bank shall irrevocably and unconditionally purchase and
receive from the Administrative 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 Administrative 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
Administrative Agent by any Bank, the Administrative 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 Administrative
Agent shall, subject to reimbursement to the Administrative 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 Administrative
Agent in respect of such Revolving Credit Loan.

2.7.4. The Administrative 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.	 	 
	 	 	 	2.8.1.	 	 	The Loans shall bear interest as follows:

(a) The outstanding principal amount of the Base Rate Loans shall bear interest on each
day at the Adjusted Base Rate for that day, but in any event not less than the rate of three
percent (3%) per annum. Any change in the Adjusted Base 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.

(b) The outstanding principal amount of each LIBOR Loan shall bear interest for the
applicable Interest Period at the Adjusted LIBOR Rate applicable to such Interest Period,
but in any event not less than the rate of three percent (3%) per annum.

(c) The outstanding principal amount of each Swing Line Loan shall bear interest on
each day at the Adjusted Base Rate for that day, but in any event not less than the rate of
three percent (3%) per annum.

2.8.2. Interest on each Loan shall be calculated on the basis of a year consisting of 360 days
and for the actual number of days elapsed.

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

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

(b) For each LIBOR Loan, on the earlier of the last day of the Interest Period with
respect to such LIBOR Loan and, if the applicable Interest Period begins in one calendar
quarter and ends in a subsequent calendar quarter, on the first day of each calendar quarter
during such Interest Period.

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

2.8.4. Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee
or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity,
upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before
judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2%
plus the rate otherwise applicable to such Loan, or (ii) in the case of any other amount,
2% plus the Adjusted Base Rate.

2.9. Unused Portion Fee. The Borrower agrees to pay to the Administrative Agent for the account of
the Banks an Unused Portion Fee on the average daily unused portion of the Revolving Credit
Commitment from the Effective Date until the Termination Date at the rate determined in accordance
with the Pricing Schedule. The Unused Portion Fee shall be payable in arrears on the first
(1st) day of each quarter during the term of this Agreement and on the Termination Date.
Upon receipt of any Unused Portion Fees, the Administrative 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.

2.10. Notes. The Revolving Credit Loans made by the Banks under this Agreement shall be evidenced
by the Notes. 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.

	 	 	 	 	 	 	 
	2.11.	 	Required Payments.
	
 
	 	 	2.11.1.	 	 	All Revolving Credit Loans shall be repaid in full on the Termination Date.

2.11.2. Upon each redetermination by the Administrative Agent pursuant to Section 1.5 of the
amount of the Available Borrowing Base then in effect, if the Aggregate Outstanding Credit Exposure
exceeds the Available Borrowing Base (as so determined by the Administrative Agent), then within
ten Business Days after receipt of notice from the Administrative Agent of the redetermined amount
of the Available Borrowing Base, the Borrower shall prepay Revolving Credit Loans (or, if
necessary, cash collateralize the outstanding Letters of Credit) in an aggregate amount equal to
such excess. To the extent any required prepayment would be applied to outstanding LIBOR Loans and
no Default or Matured Default has occurred and is continuing, such portion, including interest
thereon through the end of the then-current Interest Period applicable thereto, shall be deposited
in a deposit account with the Administrative Agent, such account to be under the sole dominion and
control of the Administrative Agent and not subject to withdrawal by the Borrower, and withdrawn
for application to such LIBOR Loans at the end of the then-current Interest Periods applicable
thereto (or earlier, upon and at any time after the occurrence and continuance of a Matured
Default). The Administrative Agent shall not pay any interest to the Borrower on any amounts held
in such account.

2.11.3. Upon any reduction of the Revolving Credit Commitment pursuant to Section 2.3.1 or
2.3.2, the Borrower will be required to prepay Revolving Credit Loans (or, if necessary, cash
collateralize outstanding Letters of Credit) to the extent the Aggregate Outstanding Credit
Exposure exceeds the reduced amount of the Revolving Credit Commitment.

2.12. Optional Prepayments. The Borrower may, upon at least one Business Day’s prior notice to the
Administrative Agent in the case of Base Rate Loans and at least three Business Days’ prior notice
to the Administrative Agent in the case of LIBOR Loans, pay the Loans, 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 Administrative Agent will promptly
thereafter cause to be distributed such payment to each Bank for the account of its applicable
Lending Office its Pro Rata Share of such payment.

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 Administrative Agent at its Principal Office for the account of the applicable
Lending Office of each Bank in immediately available funds. The Administrative 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 the Administrative Agent and 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 Loans hereunder shall be used by the Borrower for
general corporate purposes including financing Permitted Acquisitions, working capital, drawings
under Letters of Credit, and Capital Expenditures. All Loans outstanding under the Existing Credit
Agreement as of the Effective Date shall be continued as Loans made hereunder. 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 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 U.

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 Administrative 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 Administrative Agent
determines (which determination shall be conclusive) that 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 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
Administrative 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 Administrative 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 30 days’ prior notice to the Borrower from a Bank
(with a copy to the Administrative Agent), the Borrower shall pay to the Administrative 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
Effective Date 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 Administrative Agent) of any
event occurring after the Effective Date 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 Administrative 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 Administrative Agent) of any
event occurring after the Effective Date 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
Administrative Agent) the Borrower shall pay to the Administrative 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 (a) any payment of a
LIBOR Loan on a date other than the last day of the Interest Period for such Loan, including
payment upon acceleration of the Loans by the Administrative Agent pursuant to Section 8.1 or any
prepayment of a LIBOR Loan under Sections 2.15 or 2.16; or (b) 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. 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 Effective Date
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. The Borrower shall deliver to the Administrative 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.

2.20.3. 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. 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 Administrative 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
Rate Loans and thereafter may be continued as Base Rate 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
Administrative 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 Administrative Agent of any amount due under this Section 2.20.4, the
Administrative Agent shall be entitled to receive, retain and apply against such obligation the
principal and interest otherwise payable to such Bank hereunder until the Administrative 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 Administrative Agent of
any amount due under this Section 2.20.4, such Bank shall be deemed, at the option of the
Administrative 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.

the end of such fiscal year (other than quarterly periods completed within 45 days prior to such
date for which financial statements have not been released) and the comparable quarterly period in
the preceding fiscal year and consolidated statements of income, cash flows and a consolidated
statement of shareholders’ equity for the periods from the beginning of the fiscal years in which
such quarterly periods are included to the end of such quarterly periods, prepared by the Borrower.
All of the financial statements delivered to the Administrative Agent pursuant to this Section 4.2
(including any related schedules and/or notes) are true and correct in all material respects
(subject, as to interim statements, to changes resulting from audits and year-end adjustments),
have been prepared in accordance with GAAP consistently followed throughout the periods involved
and show all liabilities, direct and contingent, of the Borrower and its Subsidiaries required to
be shown in accordance with such principles. The balance sheets fairly present the condition of the
Borrower and its Subsidiaries as of the dates thereof, and the statements of income, cash flows and
stockholders’ equity fairly present the results of the operations of the Borrower and its
Subsidiaries and their cash flows for the periods indicated. There has been no material adverse
change in the business, property or assets, condition (financial or otherwise) operations or
prospects of the Borrower and its Subsidiaries taken as a whole since the end of the most recent
fiscal quarter for which financial statements have been furnished.

4.3. Actions Pending. Except as set forth in the filings made by the Borrower with the SEC, there
is no action, suit, investigation or proceeding pending or, to the knowledge of the Borrower,
threatened against the Borrower or any of its Subsidiaries, or any properties or rights of the
Borrower or any of its Subsidiaries, by or before any court, arbitrator or administrative or
governmental body which, taking into account and giving effect to any applicable insurance
coverage, would reasonably be expected to result in any material adverse change in the business,
property or assets, condition (financial or otherwise) or operations of the Borrower and its
Subsidiaries taken as a whole. There is no action, suit, investigation or proceeding pending or, to
the knowledge of the Borrower, threatened against the Borrower, or any of its Subsidiaries which
purports to affect the validity or enforceability of this Agreement or any Note.

4.4. Outstanding Indebtedness. Neither the Borrower nor any of its Subsidiaries has outstanding
any Indebtedness except as permitted by Section 7.2. There exists no default under the provisions
of any instrument evidencing such Indebtedness or of any agreement relating thereto.

4.5. Title to Properties. SMF has good and marketable title to each of the Mortgaged Properties,
and the Borrower and its Subsidiaries have good and marketable title to or valid leasehold
interests in each of their other respective real Properties. The Borrower and each of its
Subsidiaries have good title to all of their other respective Properties, including the Personal
Property Collateral reflected in the most recent audited balance sheet referred to in Section 4.2
(other than Properties disposed of in the ordinary course of business). None of the foregoing
Properties is subject to (a) any Lien of any kind other than Excepted Liens and Liens permitted by
Section 7.1 or (b) any interests which could materially adversely affect the intended use of such
Properties. All leases necessary in any material respect for the conduct of the respective
businesses of the Borrower and its Subsidiaries are valid and subsisting and are in full force and
effect. STI does not own any Properties other than the outstanding Equity Interests of SMF, and SCS
does not own any Properties other than any common law rights in its corporate name.

4.6. Taxes. The Borrower has and each of its Subsidiaries (i) has filed all federal income tax
returns which are required to be filed, (ii) to the best knowledge of the Authorized Officers of
the Borrower and its Subsidiaries, has filed all state and other income tax returns which are
required to be filed, and (iii) has paid all taxes as shown on such returns and on all assessments
received by it to the extent that such taxes have become due, except such taxes as are being
contested in good faith by appropriate proceedings for which adequate reserves have been
established in accordance with GAAP.

4.7. Conflicting Agreements and Other Matters. Neither the Borrower nor any of its Subsidiaries is
a party to any contract or agreement or subject to any charter or other corporate restriction which
materially and adversely affects its business, property or assets, condition (financial or
otherwise) or operations. Neither the execution nor delivery of this Agreement or any other Loan
Documents, nor fulfillment of nor compliance with the terms and provisions hereof and thereof, will
conflict 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. Except as set forth in the
Prudential Agreement, neither the Borrower nor any of its Subsidiaries is a party to, or otherwise
subject to any provision contained in, any instrument evidencing Indebtedness of the Borrower or
such Subsidiary, any agreement relating thereto or any other contract or agreement (including its
charter) which limits the amount of, or otherwise imposes restrictions on the incurring of,
Indebtedness of the Borrower of the type to be evidenced by the Notes.

4.8. Use of Proceeds.

4.8.1. None of the proceeds of the Loans will be used, directly or indirectly, for the
purpose, whether immediate, incidental or ultimate, of purchasing or carrying any “margin stock” as
defined in Regulation U 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 U or any other regulation of the
Board of Governors of the Federal Reserve System or to violate the Securities Exchange Act of 1934,
in each case as in effect now or as the same may hereafter be in effect.

4.8.2. None of the proceeds of any Loan will be used to finance any offer to purchase, or any
purchase of, Equity Interests in any other Person, or securities convertible into or representing
the beneficial ownership of, or rights to acquire, any such Equity Interests, if such Equity
Interests, securities or rights are of a class which is publicly traded on any securities exchange
or in any over-the-counter market, other than purchases of such Equity Interests, securities or
rights (other than margin stock) representing less than 5% of the Equity Interests or beneficial
ownership of such Person for portfolio investment purposes, if such offer or purchase has not been
duly approved by the Equity Interest holders or the board of directors or equivalent governing body
of such other Person prior to the date on which the Borrower requests that the Banks advance funds
under such Loan.

4.9. ERISA. The Borrower and each Commonly Controlled Entity have satisfied the minimum funding
standard (as defined in section 302 of ERISA and section 412 of the Code), with respect to each
Plan (other than a Multiemployer Plan), and no waiver of such minimum funding standard has been
sought or granted. No liability to the PBGC has been or is expected by the Borrower or any Commonly
Controlled Entity to be incurred with respect to any Plan (other than a Multiemployer Plan) by the
Borrower or any Commonly Controlled Entity 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 funding target attainment percentage (as defined in section
303(d) of ERISA and section 430(d) of the Code) for each Plan (other than a Multiemployer Plan) is
not less than 80 percent. Neither the Borrower nor any Commonly Controlled Entity has incurred or
currently 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.

4.10. 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 this
Agreement or any other Loan Documents 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 or other Loan
Documents or fulfillment of or compliance with the terms and provisions hereof or thereof, except
for filings with governmental bodies required in order to perfect the Collateral Agent’s Liens on
the Collateral.

4.11. 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 would not be reasonably expected to 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.

4.12. 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.

4.13. 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 reasonably foresee) materially adversely affect the business, property or assets, condition
(financial or otherwise) or operations of the Borrower or any of its Subsidiaries taken as a whole
and which has not been set forth in this Agreement.

4.14. Interstate Commerce Act. Neither the Borrower nor any Subsidiary is a “rail carrier” or a
person controlled by or affiliated with a “rail carrier” within the meaning of Title 49, U.S.C.,
and the Borrower is not a “carrier” to which 49 U.S.C. Section 11301(b)(1) is applicable.

4.15. Solvency. Each of the Borrower and SMF (assuming with respect to SMF, that the fraudulent
transfer savings language contained in the Guaranty applicable to SMF will be given full effect,
and assuming with respect to the Borrower that the Prudential Note Guaranties and the Guaranty are
disregarded as obligations of SMF) is, and after the making of each Loan hereunder will be,
Solvent.

4.16. Security Interests.

4.16.1. The Security Agreement is effective to create in favor of the Collateral Agent, for
the ratable benefit of the Secured Parties, a legal, valid and enforceable security interest in the
Collateral (as defined in such Security Agreement) and, when financing statements in appropriate
form are filed in the applicable UCC filing offices, the Security Agreement will constitute a fully
perfected Lien on, and security interest in, all right, title and interest of the grantors
thereunder in such portion of the Personal Property Collateral in which a security interest may be
perfected by the filing of a financing statement under the UCC, in each case prior and superior in
right to any other Person, other than Excepted Liens.

4.16.2. Each Mortgage with respect to a related Mortgaged Property is or will be effective to
create in favor of the Collateral Agent for the ratable benefit of the Secured Parties a legal,
valid and enforceable Lien on such Mortgaged Property and, when appropriate filings or
registrations are made with the county clerk or recorder of the county in which such Mortgaged
Property is located, such Mortgage will constitute a fully perfected Lien on all right, title and
interest of the Borrower in such Mortgaged Property, prior and superior in right to any other
Person, other than Excepted Liens.

4.17. Insurance. The properties of the Borrower and its Subsidiaries are insured with financially
sound and reputable insurance companies not Affiliates of the Borrower or any Subsidiary, in such
amounts, after giving effect to any self-insurance compatible with the following standards, with
such deductibles and covering such risks as are customarily carried by companies engaged in similar
businesses and owning similar properties in localities where the Borrower or any Subsidiary
operates. The insurance coverage of the Borrowers and its Subsidiaries as in effect on the
Effective Date is outlined as to carrier, policy number, expiration date, type, amount and
deductibles on Schedule 4.17.

	5.	 	AFFIRMATIVE COVENANTS

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;

standing selected by the Borrower whose report shall be without limitation as to scope of the audit

respect to consolidated financial statements so long as such statements contained in such Annual

5.1.3. together with each delivery of financial statements required by Sections 5.1.1 and

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;

5.1.5. within 45 days after the end of each quarterly period (other than the last quarterly

operations, financial or otherwise, of the Borrower or any of its Subsidiaries as the
Administrative Agent or any Bank may reasonably request.

5.2. Inspection of Property; Collateral Due Diligence.

5.2.1. 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 the Borrower and its Subsidiaries with the principal officers of the Borrower and its
independent public accountants, all at such reasonable times and as often as any Bank may
reasonably request.

5.2.2. The Borrower will permit the Administrative Agent to obtain an appraisal of each
Mortgaged Property within 120 days following the Effective Date. Each appraisal shall be prepared
by an MAI real estate appraiser selected by the Administrative Agent, shall be conducted in
accordance with all applicable requirements imposed pursuant to title XI of the Financial
Institutions Reform, Recovery and Enforcement Act of 1989 (FIRREA)), and shall be satisfactory in
form and substance to the Administrative Agent in the reasonable exercise of its sole discretion.
Updated appraisals of each Mortgaged Property may be requested by the Administrative Agent at any
time in the Administrative Agent’s reasonable exercise of its sole discretion. The Borrower will
pay all reasonable costs and expenses actually incurred by the Administrative Agent in connection
with each appraisal of each Mortgaged Property; provided, however, that prior to
the occurrence of any Default or Matured Default, the Borrower shall not be required to pay the
costs of more than one appraisal per year for each Mortgaged Property.

5.2.3. The Borrower will permit the Administrative Agent, through its authorized agents and
representatives (who need not be employees of the Administrative Agent), to conduct periodic field
audits of the Borrower and its Subsidiaries and to review its operations, books and records, credit
policies, charge-off policies, collection procedures, methodology for eligibility calculations, and
other matters relating to the value and maintenance of the Eligible Accounts and the Borrower’s
financial reporting. The initial field audit will be conducted within 120 days following the
Effective Date and subsequent field audits will be conducted annually thereafter. Additional field
audits may be conducted at any time in the Administrative Agent’s reasonable exercise of its sole
discretion. The Borrower will pay all reasonable costs and expenses actually incurred by the
Administrative Agent in connection with the initial field audit and each field audit thereafter;
provided, however, that prior to the occurrence of any Default or Matured Default,
the Borrower shall not be required to pay the costs of more than one field audit per year.

5.2.4. The Borrower will permit the Administrative Agent to order and obtain desktop
appraisals of the Borrower’s Rolling Stock (meaning appraisals of limited scope whereby the
appraiser estimates the value of the Rolling Stock from his or her desk based on a current listing
supplied to him or her, but without conducting a physical inspection of the Rolling Stock). Each
desk-top appraisal shall be conducted by a qualified appraiser selected by the Administrative Agent
and shall set forth the appraiser’s estimate of the Net Orderly Liquidation Value of the Borrower’s
Rolling Stock. The initial desktop appraisal will be conducted within 90 days following the
Effective Date and subsequent desktop appraisals will be obtained annually thereafter. Additional
desktop appraisals may be conducted at any time in the Administrative Agent’s reasonable exercise
of its sole discretion. The Borrower will pay all reasonable costs and expenses actually incurred
by the Administrative Agent in connection with the initial desktop appraisal and each desktop
appraisal thereafter; provided, however, that prior to the occurrence of any
Default or Matured Default, the Borrower shall not be required to pay the costs of more than one
desktop appraisal per year.

5.3. Covenant to Secure Obligations Equally. If the Borrower or any Subsidiary shall create or
assume any Lien upon any of its Properties, whether now owned or hereafter acquired, other than (i)
with respect to Indebtedness permitted under Section 7.2, Liens affecting assets of a Person
acquired by the Borrower or one of its Subsidiaries (which Liens must be released and the debt
secured thereby extinguished within forty-five (45) days following the consummation of the
Acquisition), (ii) Liens permitted by the provisions of Section 7.1, and (iii) Liens created or
assumed with the prior written consent of the Collateral Agent and the Majority Banks, the Borrower
shall make or cause to be made effective provision whereby the Obligations and the Prudential
Obligations 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.

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 and 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 would 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.

5.5.1. The Borrower will, and will cause each of its Subsidiaries to, maintain with
financially sound and reputable insurance companies not Affiliates of the Borrower or any of its
Subsidiaries, (i) insurance with respect to its Properties and business against such casualties and
contingencies, of such types, on such terms and in such amounts as is customarily carried by
companies engaged in similar businesses and owning similar properties in localities where the
Borrower or any Subsidiary operates and (ii) such other insurance as may be required by the Loan
Documents or applicable law.

5.5.2. The Borrower will, and will cause each of its Subsidiaries to, cause all such policies
covering any Collateral to be endorsed or otherwise amended to include a customary lender’s loss
payable endorsement or to name the Collateral Agent as an additional insured, in form and substance
satisfactory to the Collateral Agent, which endorsement shall provide that, from and after the
Effective Date, if the insurance carrier shall have received written notice from the Collateral
Agent of the occurrence of a Matured Default, the insurance carrier shall pay all proceeds
otherwise payable to the Borrower or a Subsidiary under such policies directly to the Collateral
Agent; (ii) deliver original or certified copies of all such policies to the Collateral Agent;
cause each such policy to provide that it shall not be canceled, modified or not renewed upon not
less than 30 days’ prior written notice thereof by the insurer to the Collateral Agent; and (iii)
deliver to the Collateral Agent, prior to the cancellation, modification or nonrenewal of any such
policy of insurance, a copy of a renewal or replacement policy (or other evidence of renewal of a
policy previously delivered to the Collateral Agent) together with evidence satisfactory to the
Collateral Agent of payment of the premium therefor.

5.5.3. If at any time the area in which any Mortgaged Property is located is designated a
“flood hazard area” in any Flood Insurance Rate Map published by the Federal Emergency Management
Agency (or any successor agency), the Borrower will, or will cause SMF, to obtain flood insurance
in such total amount as required by Regulation H of the Federal Reserve Board, as the same is from
time-to-time in effect, and all official rulings and interpretations thereunder or thereof may from
time to time require, and otherwise comply with the National Flood Insurance Program as set forth
in the Flood Disaster Protection Act of 1973, as it may be amended from time to time.

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. ERISA. The Borrower covenants that it and each of its Commonly Controlled Entities will
deliver to the Administrative 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
Commonly Controlled Entity has participated, now participates or will participate in any Plan or
Multiemployer Plan, the Borrower covenants that it and any such Commonly Controlled Entity will
deliver to the Administrative 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 the
Administrative 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 Commonly Controlled Entity’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 Commonly Controlled
Entity may receive from the PBGC or the Internal Revenue Service with respect to any Plan or
Multiemployer Plan; provided, however, that this Section 5.9 shall not apply to
notices of general application promulgated by the PBGC or the Internal Revenue Service.

5.10. Environmental Covenants.

5.10.1. The Borrower will maintain an environmental management system that is designed (A) to
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.

5.10.2. The Borrower will immediately notify the Administrative Agent of and provide the
Administrative Agent with copies of any notifications of violations or notifications of discharges
or releases or threatened releases or discharges of a Hazardous Materials on, upon, into or from
any property of the Borrower or any Subsidiary, or any property where the Borrower or its
Subsidiaries is conducting operations, which 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 the Administrative Agent at
the same time as they are delivered to the governmental agency or authority.

5.10.3. 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
or threatened release or discharge of a Hazardous Material on, upon, into or from any property of
the Borrower or any Subsidiary.

5.10.4. At all times, the Borrower will maintain and retain, or cause its Subsidiaries to
maintain and retain, to the extent legally required, complete and accurate records of all releases,
discharges or other disposal of Hazardous Materials on, onto, into or from (A) any Property of the
Borrower or any Subsidiary, or (B) any Property on or adjacent to which the Borrower or any of its
Subsidiaries conducts operations (“Third Party Property”) if such releases, discharges, or other
disposal on Third Party Properties is caused by the Borrower or any of its Subsidiaries or any
Person under its control or acting on its behalf and to the extent such failure to maintain such
records would have a material adverse effect on the business, condition (financial or otherwise) or
operations of the Borrower and its Subsidiaries, taken as a whole.

5.11. Maintenance of Collateral; Pledge of Additional Collateral.

5.11.1. Subject to Sections 5.12 and 5.13, the Borrower will, and will cause each of STI and
SMF to, grant to the Collateral Agent an Acceptable Security Interest in each item or type of
Property included in the Collateral; provided, however, that prior to the
occurrence of any Default, the Borrower and its Subsidiaries will not be required to take steps to
perfect the Collateral Agent’s Liens on deposit accounts, trademarks, patents, promissory notes,
instruments, or other Personal Property Collateral (other than Rolling Stock, as provided in
Section 5.13) as to which perfection is not accomplished by the filing of one or more UCC financing
statements.

5.11.2. Within thirty (30) days after any other Person becomes a Subsidiary, (a) cause such
Person to (i) become a Guarantor by executing and delivering to the Administrative Agent a
supplement to the Guaranty or such other document as the Administrative Agent shall deem
appropriate for such purpose, (ii) deliver to the Administrative Agent documents of the types
referred to in Section 3.1 and favorable opinions of counsel to such Person (which shall cover,
among other things, the legality, validity, binding effect and enforceability of the documentation
referred to in clause (i)), all in form, content and scope reasonably satisfactory to the
Administrative Agent, and (iii) execute such Collateral Documents as the Collateral Agent or the
Majority Banks may reasonably request, in each case to secure the Obligations, and (b) cause the
immediate parent of such Subsidiary to pledge 100% of the Equity Interest in such Subsidiary to
secure the Obligations and provide such legal opinions relating thereto as the Administrative Agent
may reasonably request, along with share certificates pledged thereby and appropriately executed
stock powers in blank.

5.12. Mortgaged Properties.

5.12.1. Within 60 days following the Effective Date, the Borrower shall cause SMF (or other
record owner of any Mortgaged Property) to execute and deliver to the Collateral Agent, as
collateral agent for the benefit of the Secured Parties, a Mortgage covering each Mortgaged
Property described on Schedule 1.1.77 hereof, together with any other documents, agreements or
instruments necessary to create a mortgage Lien on such Mortgaged Property (but only upon the
Collateral Agent’s receipt of verification that such Mortgaged Property is not located in an area
designated by the Federal Emergency Management Agency as having special flood or mud slide
hazards). Within 120 days following the Effective Date, the Borrower shall deliver to the
Collateral Agent all appropriate documentation and evidence required by the Collateral Agent
necessary to determine that arrangements have been made for the Collateral Agent, for the benefit
of Secured Parties, to have an Acceptable Security Interest in each of the Mortgaged Properties
described on Schedule 1.1.77, including as to each such Mortgaged Property:

(a) if requested by the Collateral Agent, a favorable opinion from local counsel
located in the jurisdiction of such Mortgaged Property;

(b) an ALTA lender’s title insurance policy (or commitment for the issuance thereof)
issued by a title insurer reasonably satisfactory to the Collateral Agent, in form and
substance and in amounts reasonably satisfactory to the Collateral Agent insuring that such
Mortgage creates a valid and enforceable first priority mortgage Lien on such Mortgaged
Property, free and clear of all defects and encumbrances except Excepted Liens, and
containing such endorsements as the Administrative Agent may reasonably request;

(c) a current survey of such Mortgaged Property, certified by a licensed or registered
surveyor, to the extent required in order for the title insurer to delete the standard
survey exception from the title insurance policy covering such Mortgaged Property;

(d) if requested by the Collateral Agent or the title insurer, satisfactory evidence
that such Mortgaged Property is zoned for its current use; and

(e) a “Phase I” environmental assessment report (and if recommended in the “Phase I”
environmental assessment report and requested by the Collateral Agent, a “Phase II”
environmental assessment report) covering such Mortgaged Property prepared by an
environmental engineering firm acceptable to the Collateral Agent and reflecting that the
environmental condition of such Mortgaged Property is acceptable (such determination to be
made by the Collateral Agent in the reasonable exercise of its sole discretion).

5.12.2. If a Phase I environmental assessment report recommends a Phase II environmental
assessment report with respect to any Mortgaged Property described in Schedule 1.1.77 and if the
Collateral Agent requests such a “Phase II” environmental assessment report or further
environmental due diligence, or if a title defect (other than an Excepted Lien) is discovered with
respect to any Mortgaged Property described in Schedule 1.1.77 that the Borrower is unable to cure,
the Borrower may elect to withdraw such Mortgaged Property from the Borrowing Base (and with
respect to a request for a “Phase II” environmental assessment report or further environmental due
diligence, also elect not to obtain or furnish the requested report or information), but within 60
days of such election the Borrower shall grant or cause SMF to grant the Collateral Agent an
Acceptable Security Interest in a substitute terminal facility or facilities acceptable to the
Collateral Agent and having an Appraised Value comparable to the Mortgaged Property so withdrawn.
Upon providing an Acceptable Security Interest in the terminal facility or facilities so
substituted, the substitute facilities will be Mortgaged Properties for purposes of this Agreement
and the Appraised Value thereof will be included in the calculation of the Borrowing Base.

5.12.3. The Borrower may at any time grant or cause to be granted an Acceptable Security
Interest in favor of the Collateral Agent on other real Properties owned by the Borrower or any of
its Subsidiaries. Upon the Collateral Agent’s being provided an Acceptable Security Interest
therein, such Properties will be Mortgaged Properties for purposes of this Agreement and the
Appraised Value thereof will be included in the calculation of the Borrowing Base.

5.13. Rolling Stock. Within 90 days following the Effective Date, the Borrower shall deliver to
the Collateral Agent all appropriate documentation and evidence reasonably required by the
Collateral Agent necessary to determine that arrangements have been made for the Collateral Agent,
for the benefit of Secured Parties, to have an Acceptable Security Interest in Rolling Stock
representing at least 85% of the amount of the initial Net Orderly Liquidation Value of the
Borrower’s Rolling Stock as set forth in the appraisal to be delivered pursuant to Section 5.2.4.
Such arrangements shall include (i) the Borrower’s execution and delivery of such agreements as the
Vehicle Title Service Company may reasonably require, (ii) the Borrower’s delivery to the Vehicle
Title Service Company of the certificates of title covering Rolling Stock that, when combined with
Rolling Stock as to which perfection of the Collateral Agent’s has been accomplished through the
filing of financing statements pursuant to the UCC, represents at least 85% of the Net Orderly
Liquidation Value of the Borrower’s Rolling Stock and notation of the Collateral Agent’s Lien on
each certificate of title so delivered, and (iii) the Borrower’s payment of the normal set-up and
services charges of the Vehicle Title Service Company and the filing fees payable in connection
with the notation of the Collateral Agent’s Lien on each certificate of title so delivered.
Thereafter, so long as no Default has occurred and is continuing, the Borrower shall cause the
Collateral Agent, for the benefit of Secured Parties, at all times to have an Acceptable Security
Interest in Rolling Stock representing at least 85% of the amount of the current Net Orderly
Liquidation Value of the Borrower’s Rolling Stock. Upon the request of the Collateral Agent
following the occurrence of any Default, the Borrower will cooperate with the Vehicle Title Service
Company in causing the certificates of title on all Rolling Stock to be promptly delivered to the
Vehicle Title Service Company and in causing the Collateral Agent’s Lien to be noted on each
certificate of title.

5.14. Merger of STI. The Borrower shall cause STI to be merged with and into the Borrower, with
the Borrower as the surviving corporation, on or before June 30, 2009, and within 30 days following
the Effective Date shall deliver to the Administrative Agent and the Collateral Agent appropriate
documentation to evidence that such merger has been completed in accordance with all applicable
legal requirements.

organized and existing under the laws of any state of the United States of America, or the
District of Columbia, with substantially all of its assets located and substantially all of
its operations conducted within the United States of America, and such continuing or
surviving corporation expressly assumes, by a written agreement satisfactory in form and
substance to the Majority Banks (which agreement may require, in connection with such
assumption, the delivery of such opinions of counsel as the Majority Banks may require), the
obligations of the Borrower under this Agreement and the other Loan Documents, including all
covenants herein and therein contained, and such successor or acquiring entity shall succeed
to and be substituted for the Borrower with the same effect as if it had been named herein
as a party hereto, provided, however, that no such sale shall release the

ordinary course of business; and

(c) the Borrower or any Subsidiary may otherwise Transfer Properties, provided
that after giving effect thereto (i) the aggregate value of any Properties Transferred
during the 12 consecutive months immediately preceding such Transfer does not exceed 5% of
Consolidated Tangible Assets as of the end of the fiscal quarter immediately preceding such
Transfer, provided, however, that the aggregate purchase price paid within
90 days after any such Transfer for similar assets within the United States that are not
subject to Liens (other than Excepted Liens) for borrowed money other than pursuant to this
Agreement (before or after acquisition) will be deducted in determining this 5% limit, and
(ii) the aggregate value of Properties Transferred subsequent to January 28, 2008 shall not
exceed 25% of the Consolidated Tangible Assets determined at any time by aggregating the
dollar value of all Transfers as of such time as a percentage of Consolidated Tangible

provided, however, that the aggregate purchase price paid within 90 days
after any such Transfer for similar assets within the United States that are not subject to
Liens (other than Excepted Liens) for borrowed money other than pursuant to this Agreement

Mortgaged Property without the consent of the Majority Banks, and in no event may the Borrower or
any Existing Subsidiary Transfer its Equity Interests in an Existing Subsidiary without the consent
of all of the Banks. If requested by the Borrower in order to facilitate any Transfer which is

by the requisite Banks, the Collateral Agent shall release its Lien on the Property or Properties
to be Transferred.

7.7. Sale and Lease-Back. The Borrower will not and will not permit any Subsidiary to enter into
any arrangement with any lender or investor or to which such lender or investor is a party

Person to whom funds have been or are to be advanced by such lender or investor on the security of
such Property or rental obligations of the Borrower or any Subsidiary, except for the sale

directly or indirectly, purchase, acquire or lease any Property from, or sell, transfer or lease

such Subsidiary, as the case may be, than those that could be obtained in an arm’s-length
transaction with an unrelated third party; provided that the foregoing shall not apply to
(A) any transaction between the Borrower and any Wholly Owned Subsidiary or between Wholly Owned
Subsidiaries and (B) any sales to, or purchases from, any such Related Party of shares of common

directly, or indirectly by the issuance of rights or options for, or securities convertible into,
such shares) to issue, sell or dispose of any of its Equity Interests except (i) for directors’

otherwise acquire any material Property, in either case not directly related to the conduct of its
business or operations as presently carried on.

Subsidiary, except that: (i) after the expiration of the Adjusted Covenant Period, the
Borrower may purchase, redeem, retire, acquire, cancel or terminate any of its Equity
Interests up to the aggregate amount of $50,000,000, provided that (A) the Borrower’s pro
forma Leverage Ratio following any such transaction shall be less than or equal to 2.75 to
1.00 and (B) the Borrower’s pro forma Available Liquidity following any such transaction
shall be greater than or equal to $30,000,000; and (ii) the Borrower may make purchases of

or interest on, any Indebtedness for borrowed money if any Default or Matured Default exists

7.14. Most Favored Lender Status.

7.14.1. The Borrower will not enter into or permit any amendment to the Prudential Agreement
or any other Prudential Note Document to include one or more Additional Covenants or Additional
Defaults, unless prior written consent to such amendment shall have been obtained from the Majority
Banks; provided, however, in the event that any such amendment shall be entered into
without the prior written consent of the Majority Banks, the terms of this Agreement shall, without
any further action on the part of the Borrower, the Majority Banks or the Administrative Agent, be
deemed to be amended automatically to include each Additional Covenant and each Additional Default
contained in such amendment. 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 Administrative
Agent) an amendment to this Agreement in form and content satisfactory to the Majority Banks
evidencing the amendment of this Agreement to include such Additional Covenants and Additional
Defaults to which the Majority Banks granted consent, provided that the execution and delivery of
such amendment shall not be a precondition to the effectiveness of such amendment as provided for
in this Section 7.14.1, but shall merely be for the convenience of the parties hereto.

7.14.2. The Borrower will not enter into or amend any agreement governing or evidencing
Indebtedness for borrowed money (other than the Prudential Agreement and other than Capital Leases)
in a principal amount committed or outstanding of $10,000,000 or more under one agreement, or a
series of related agreements, that includes one or more Additional Covenants or Additional Defaults
(other than covenants pertaining to the conversion of such Indebtedness to equity), unless prior to
entering into such agreement or amendment, (i) the Borrower offered such Additional Covenant or
Additional Default to the Banks and (ii) if the Majority Banks have accepted such Additional
Covenant or Additional Default, the Borrower has executed and delivered at its expense (including
the reasonable fees and expenses of counsel for the Banks and the Administrative Agent) an
amendment to this Agreement to include such Additional Covenants and Additional Defaults in this
Agreement, provided that in no event shall the Borrower enter into or amend any agreement
to restrict payments on the Obligations or restrict the ability of the Borrower to enter into
amendments and modifications of this Agreement or the other Loan Documents without the prior
written consent of the Majority Banks; provided, further, in the event that the
Borrower or any Subsidiary shall enter into, assume or otherwise become bound by or obligated under
any such agreement that includes Additional Covenants or Additional Defaults, without executing and
delivering such amendment to this Agreement, the terms of this Agreement shall, without any further
action on the part of the Borrower, the Majority Banks or the Administrative Agent, be deemed to be
amended automatically to include each Additional Covenant and each Additional Default contained in
such agreement.

consent of, the Majority Banks, by written notice to the Borrower, (1) declare the Commitments to
be terminated, whereupon the same shall forthwith terminate; (2) declare the outstanding Notes, all
interest thereon, and all other Obligations to be forthwith due and payable, whereupon the Notes,

waived by the Borrower; (3) demand that the Borrower immediately pay to the Administrative Agent
the full amount then available for drawing under each or any Letter of Credit to be held by the

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 Administrative 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.

8.2. Remedies. Upon the occurrence and during the continuance of any Matured Default, the
Administrative Agent shall at the request of, or may with the consent of, the Majority Banks
proceed to enforce its rights and remedies under the Collateral Documents, this Agreement, and any
other Loan Document for the ratable benefit of the Secured Parties by appropriate proceedings.
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 Administrative 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 Administrative 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.

8.3. 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.

8.4. Application of Proceeds. From and during the continuance of any Matured Default, any monies
or property actually received by the Administrative Agent or the Collateral Agent pursuant to this
Agreement or any other Loan Document, the exercise of any rights or remedies under any Collateral
Document or any other agreement with the Borrower or any Subsidiary which secures any of the
Obligations, shall be applied in the following order (subject to the applicable sharing provisions
of the Prudential Intercreditor Agreement):

(a) First, to payment of the reasonable expenses, liabilities, losses, costs,
duties, fees, charges or other moneys whatsoever (together with interest payable thereon) as
may have been paid or incurred in, about or incidental to any sale or other realization of
Collateral, including reasonable compensation to the Administrative Agent and its agents and
counsel, and to the ratable payment of any other unreimbursed reasonable expenses and
indemnities for which the Administrative Agent, the Collateral Agent or any Bank is to be
reimbursed pursuant to this Agreement or any other Loan Document, in each case that are then
due and payable;

(b) Second, to the ratable payment of accrued but unpaid fees of the
Administrative Agent, Unused Portion Fees, letter of credit fees owing to the Administrative
Agent and the Banks under this Agreement;

(c) Third, to the ratable payment of accrued but unpaid interest on the Loans
and any unpaid L/C Obligations then due and payable under this Agreement;

(d) Fourth, to the Collateral Agent to cash collateralize the L/C Obligations;

(e) Fifth, ratably, according to the then unpaid amounts thereof, without
preference or priority of any kind among them, to the ratable payment of all other
Obligations then due and payable which relate to Loans and Letters of Credit and which are
owing to the Administrative Agent, the Collateral Agent and the Banks;

(f) Sixth, ratably, according to the unpaid termination amounts thereof, to the
payment of all Rate Management Obligations of the Borrower or its Subsidiaries owing to any
Bank (or Affiliate of any Bank), to the extent then due and payable;

(g) Seventh, ratably according to the unpaid amounts thereof, to the payment of
all Obligations owing to the Banks with respect to any Treasury Management Agreements;

(h) Eighth, to the ratable payment of any other Obligations then due and
payable; and

the Borrower or to such other Person who may be lawfully entitled to receive such excess.

	9.	 	AGENCY PROVISIONS

9.1. Authorization and Action. Each Bank hereby appoints Bank of Oklahoma, N.A., to act on its
behalf as the Administrative Agent and Collateral Agent hereunder and under the other Loan
Documents and authorizes each Agent to take such action as agent on its behalf and to exercise such
powers under this Agreement as are delegated to such Agent by the terms hereof, together with such
powers as are reasonably incidental thereto. The duties of each Agent shall be mechanical and
administrative in nature, and neither Agent shall by reason of this Agreement be a trustee or
fiduciary for any Bank. Neither Agent shall have any duties or responsibilities except those
expressly set forth herein or in the Prudential Intercreditor Agreement. As to any matters not
expressly provided for by this Agreement (including enforcement or collection of the Obligations),
neither 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 neither Agent shall be
required to take any action which exposes such Agent to personal liability or which is contrary to
this Agreement or applicable law.

9.2. Liability of Agents. Neither of the Agents 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, each Agent (1) may treat the
payee of any Note as the holder thereof until such Agent receives written notice of the assignment
or transfer thereof signed by such payee and in form satisfactory to such 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 Properties (including the books and
records) of the Borrower and its Subsidiaries; (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, each 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 an Agent; and the term “Bank” or “Banks”
shall, unless otherwise expressly indicated, include each Agent in its individual capacity. Each of
the Agents 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 such Agent were not an 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 Agents 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 either 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 Administrative Agent by the Borrower or any Subsidiary hereunder or under any other Loan
Document (each of which the Administrative Agent shall promptly upon receipt provide to each Bank),
the Administrative 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
Administrative Agent or any of its Affiliates.

9.5. Indemnification. The Banks agree to indemnify each of the Agents (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 either Agent in any way relating to or arising out of this
Agreement or any action taken or omitted by either Agent under this Agreement or any of the other
Loan Documents, provided that no Bank shall be liable for any portion of any of the foregoing
resulting from such Agent’s gross negligence or willful misconduct. Without limitation of the
foregoing, each Bank agrees to reimburse each of the Agents (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 such Agent in connection with the preparation, administration, or
enforcement of, or legal advice in respect of rights or responsibilities under, this Agreement or
any of the other Loan Documents.

9.6. Successor Agent. Each 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 an 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 and the other Loan Documents. 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 an
Agent under this Agreement.

9.7. 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.

9.8. Collateral and Guaranty Matters.

9.8.1. Each Bank and each other Secured Party (by its acceptance of the benefits of any Lien
encumbering Collateral) acknowledges and agrees that the Collateral Agent has entered into the
Collateral Documents on behalf of itself and the Secured Parties, and the Secured Parties hereby
agree to be bound by the terms of such Collateral Documents, acknowledge receipt of copies of such
Collateral Documents and consent to the rights, powers, remedies, indemnities and exculpations
given to the Collateral Agent thereunder. All rights, powers and remedies available to the
Collateral Agent and the Secured Parties with respect to the Collateral, or otherwise pursuant to
the Collateral Documents, shall be subject to the provisions of such Collateral Documents.

(a) Each Bank and each other Secured Party (by its acceptance of the benefits of any
Lien encumbering Collateral) hereby authorizes the Collateral Agent, at its option and in
its discretion, without the necessity of any notice to or further consent from the Secured
Parties:

(b) to release any Lien on any property granted to or held by the Collateral Agent
under any Collateral Document (i) upon termination of the Commitments and payment in full of
all Obligations (other than contingent indemnification obligations) and the expiration or
termination of all Letters of Credit, (ii) that is Transferred or to be Transferred as part
of or in connection with any Transfer permitted hereunder or under any other Loan Document,
or (iii) subject to Sections 7.6 and 11.1, if approved, authorized or ratified in writing by
the Majority Banks;

(c) to take any actions with respect to any Collateral or Collateral Documents which
may be necessary to perfect and maintain Acceptable Security Interests in and Liens upon the
Collateral granted pursuant to the Collateral Documents; and

(d) to take any action in exigent circumstances as may be reasonably necessary to
preserve any rights or privileges of the Secured Parties under the Loan Documents or
applicable legal requirements.

9.8.2. Upon the request of the Collateral Agent at any time, the Secured Parties will confirm
in writing the Collateral Agent’s authority to release particular types or items of Collateral
pursuant to this Section 9.8.

9.8.3. The Borrower (for itself and each of its Subsidiaries) irrevocably appoints the
Collateral Agent as its attorney-in-fact, with full authority to, after the occurrence and during
the continuance of a Matured Default, act for the Borrower and each of its Subsidiaries and in the
name of the Borrower or any Subsidiary to, in the Collateral Agent’s discretion upon the occurrence
and during the continuance of a Matured Default, (i) file one or more financing or continuation
statements, and amendments thereto, relative to all or any part of the Collateral without the
signature of such party where permitted by law, (ii) to receive, endorse, and collect any drafts or
other instruments, documents, and chattel paper which are part of the Collateral, (iii) to ask,
demand, collect, sue for, recover, compromise, receive, and give acquittance and receipts for
moneys due and to become due under or in respect of any of the Collateral, (iv) to file any claims
or take any action or institute any proceedings which the Collateral Agent may reasonably deem
necessary or desirable for the collection of any of the Collateral or otherwise to enforce the
rights of the Collateral Agent with respect to any of the Collateral and (v) if the Borrower or any
Subsidiary fails to perform any covenant contained in this Agreement or the other Collateral
Documents after the expiration of any applicable grace periods, the Collateral Agent may itself
perform, or cause performance of, such covenant, and the Borrower shall pay for the expenses of the
Collateral Agent incurred in connection therewith. The power of attorney granted hereby is coupled
with an interest and is irrevocable.

9.8.4. The powers conferred on the Collateral Agent under this Agreement and the other
Collateral Documents are solely to protect its interest in the Collateral and shall not impose any
duty upon it to exercise any such powers. Beyond the safe custody thereof, the Collateral Agent
and each Secured Party shall have no duty with respect to any Collateral in its possession or
control (or in the possession or control of any agent or bailee) or with respect to any income
thereon or the preservation of rights against prior parties or any other rights pertaining thereto.
The Collateral Agent shall be deemed to have exercised reasonable care in the custody and
preservation of the Collateral in its possession if the Collateral is accorded treatment
substantially equal to that which the Collateral Agent accords its own property. None of the
Administrative Agent, the Collateral Agent, any Bank or any other Secured Party shall be liable or
responsible for any loss or damage to any of the Collateral, or for any diminution in the value
thereof, by reason of the act or omission of any warehouseman, carrier, forwarding agency,
consignee, broker or other agent or bailee selected by Borrower or selected by the Administrative
Agent or the Collateral Agent in good faith.

9.8.5. The rights, duties, protections and immunities afforded to the Collateral Agent under
the terms of the Prudential Intercreditor Agreement are in addition to the rights, duties,
protections and immunities applicable to the Collateral Agent under the terms of this Section 9.
In the event of any irreconcilable conflict between the provisions of this Agreement and the
provisions of the Prudential Intercreditor Agreement with respect to the rights, duties, protection
and immunities of the Collateral Agent, the provisions of the Prudential Intercreditor Agreement
shall govern.

9.9. No Other Duties. Anything herein to the contrary notwithstanding, the Lead Arranger, the
Syndication Agents and the Documentation Agent listed on the cover page hereof shall not have any
powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except
in its capacity, as applicable, as the Administrative Agent, the Collateral Agent or a Bank.

	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 Administrative 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 Administrative 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. 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 Administrative 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. 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. The Borrower agrees that each Participant shall be deemed to have the right of setoff
provided in Section 8.2 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 8.2 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 8.2, 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 8.2as 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. 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 Exhibit G hereto or in such
other form as may be agreed to by the parties thereto, and shall be accompanied by an executed
supplement to the Prudential Intercreditor Agreement in the form of Attachment A to the Prudential
Intercreditor Agreement. 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 Administrative 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. 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
Administrative 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. Upon (i) delivery to the Administrative Agent of an assignment, together with an
executed supplement to the Prudential Intercreditor Agreement in the form of Attachment A to the
Prudential Intercreditor Agreement and any consents required by Sections 10.3.1 and 10.3.2, and
(ii) payment of $3,500 fee to the Administrative Agent for processing such assignment (unless such
fee is waived by the Administrative 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, unless an exemption from the prohibited transaction provisions of ERISA and the Code
is available. 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 Administrative 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 Administrative 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. The Administrative 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 Administrative 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. Disclosure 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

amendment, waiver, or consent shall, unless in writing and signed by the affected Agent or the L/C
Issuer (in addition to the Banks required above to take such action) affect the rights or duties of
the Administrative Agent, the Collateral Agent or the L/C Issuer under any of the Loan Documents,

effective until received by the Administrative Agent.

11.3. No Waiver. No failure or delay on the part of any Bank or the Administrative Agent in
exercising any right, power, or remedy hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise of any such right, power, or remedy preclude any other or further
exercise thereof or the exercise of any other right, power, or remedy hereunder. The rights and
remedies provided herein are cumulative, and are not exclusive of any other rights, powers,
privileges, or remedies, now or hereafter existing, at law or in equity or otherwise.

11.4. Successors and Assigns. The Agreement shall be binding upon and inure to the benefit of the
Borrower, each Bank and the Administrative Agent and their respective successors and assigns,
except that the Borrower may not assign or transfer any of its rights under any Loan Document to
which the Borrower is a party without the prior written consent of all the Banks.

11.5. Costs, Expenses, and Taxes. The Borrower agrees to pay on demand (i) all out-of-pocket
expenses reasonably incurred by the Administrative Agent, the Collateral Agent and the L/C Issuer
in connection with the preparation, execution, delivery, filing, and administration of the Loan
Documents, and of any amendment, modification, or supplement to the Loan Documents, including the

the fees, charges and disbursements of counsel for either Agent or the L/C Issuer) in connection
with the enforcement or protection of its rights in connection with this Agreement and the other
Loan Documents, including all such out-of-pocket expenses incurred during any workout,
restructuring or negotiations in respect of the outstanding Loans or Letters of Credit. The
foregoing costs and expenses shall include the fees and charges of the Vehicle Title Service
Company, all search, filing, recording, title insurance, appraisal, and environmental assessment
fees and charges (and all taxes related thereto), and other out-of-pocket expenses incurred by
either Agent or the L/C Issuer. The Borrower also agrees to pay all such costs and expenses,
including court costs, incurred by any Bank in connection with enforcement of the Loan Documents,
or any amendment, modification, or supplement thereto, whether by negotiation, legal proceedings,
or otherwise. In addition, the Borrower shall pay any and all stamp and other taxes and fees
payable or determined to be payable in connection with the executing, delivery, filing, and
recording of any of the Loan Documents and the other documents to be delivered under any such Loan
Documents, and agrees to hold the Administrative Agent and each of the Banks harmless from and

parties relating to the subject matter hereof and supersede all oral statements and prior writings
with respect thereto.

11.7. Indemnity. The Borrower hereby agrees to defend, indemnify, and hold each Bank harmless from
and against any and all claims, damages, judgments, penalties, costs, and expenses (including
attorney fees and court costs now or hereafter arising from the aforesaid enforcement of this
clause) arising directly or indirectly from the activities of the Borrower and its Subsidiaries,
its predecessors in interest, or third parties with whom it has a contractual relationship, or

indemnity shall survive termination of this Agreement.

such prohibition or unenforceability without invalidating the remaining provisions of such Loan
Document or affecting the validity or enforceability of such provision in any other jurisdiction.

11.10. Counterparts. This Agreement may be executed in any number of counterparts and by different

PROCEEDING, CLAIM OR COUNTERCLAIM, WHETHER IN CONTRACT OR TORT, AT LAW OR IN EQUITY, ARISING OUT OF

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

11.13. USA Patriot Act Notification. IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW

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.

The foregoing shall be recalculated on not less than a quarterly basis, on the date on which
the Administrative Agent is in full receipt of the Borrower’s most recent financial statements
(and, in the case of the year-end financial statements, audit report) for the fiscal quarter then
ended, pursuant to Section 5.1 (“Pricing Date”). The applicable Pricing Level shall be established
based on the Leverage Ratio for the most recently completed fiscal quarter and shall remain in
effect until the next Pricing Date. From the Effective Date to the first Pricing Date, the Pricing
Level IV shall apply. If the Borrower has not delivered its financial statements by the date such
financial statements (and, in the case of the year-end financial statements, audit report) are
required to be delivered under Section 5.1 hereof, until such financial statements and audit report
are delivered, Pricing Level VI shall apply. If the Borrower subsequently delivers such financial
statements before the next Pricing Date, the Pricing Level established by such late delivered
financial statements shall take effect from the date of delivery until the next Pricing Date. In
all other circumstances, the Pricing Level established by such financial statements shall be in
effect from the Pricing Date that occurs immediately after the end of the fiscal quarter covered by
such financial statements until the next Pricing Date. Each determination of the Pricing Level
made by the Administrative Agent in accordance with the foregoing shall be conclusive and binding
on the Borrower and the Banks if reasonably determined.

Schedule 3.1.8

(Items to be Addressed by Opinion of Counsel)

1. The Borrower is a corporation, duly incorporated, validly existing and in good standing under
the laws of the state of Delaware. Each of STI and SCS is a corporation, duly organized, validly
existing and in good standing under the laws of the State of Delaware. SMF is a limited liability
company, duly formed, validly existing and in good standing under the laws of the state of
Louisiana. Each of the Borrower, STI and SMF (collectively, the “Loan Parties”) is qualified or
registered to do business in, and is in good standing in, every jurisdiction in which the Mortgaged
Properties are located and every other jurisdiction in which such qualification or registration is
required, except where the failure to do so, individually or in the aggregate, could not reasonably
be expected to result in a material adverse effect.

2. Each of STI, SCS and SMF is a Wholly Owned Subsidiary of the Borrower. The Borrower does not
have any Subsidiaries other than STI, SCS and SMF.

3. Each of the Loan Parties has all requisite power and authority and the legal right to own and
operate its Properties and to carry on its business as now conducted.

4. The execution, delivery and performance of the Loan Documents to which each of the Loan Parties
is a party are within its corporate or limited liability company powers, as applicable, and have
been duly authorized by all necessary corporate or limited liability company action.

5. Each of the Loan Documents has been duly executed and delivered by each of the Loan Parties
party thereto and constitutes the legal, valid and binding obligation of the Loan Parties party
thereto, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium or other laws affecting creditors’ rights generally and subject to
general principles of equity.

6. The transactions contemplated by the Loan Documents, including the borrowings thereunder and the
grant of Liens in favor of the Collateral Agent in the Collateral, (a) do not require any consent
or approval of, registration or filing with, or any other action by, any governmental agency or
authority, except such as have been obtained or made and are in full force and effect, (b) will not
violate any applicable law or regulation or the charter, by-laws or other organizational documents
of either of the Loan Parties or any order of any court, tribunal, or governmental agency or
authority, (c) will not violate or result in a default under any indenture, agreement or other
instrument binding upon either of the Loan Parties or any of their respective Properties, or give
rise to a right thereunder to require any payment to be made by the Loan Parties, and (d) will not
result in the creation or imposition of any Lien on any Property of either of the Loan Parties,
except in favor of the Collateral Agent as contemplated by the Loan Documents.

7. The Security Agreement is sufficient in form to create in favor of the Collateral Agent, for the
benefit of the Secured Parties, a valid and enforceable security interest in all right, title and
interest of the Loan Parties in the Personal Property Collateral, to the extent a security interest
in the Personal Property Collateral may be created under Article 9 of the UCC.

8. The financing statements, including the descriptions of the collateral covered thereby, comply
with the applicable requirements of the UCC. Upon the filing of the financing statements in the
UCC records of the Delaware Secretary of State (as to the Borrower and STI) and the Louisiana
Secretary of State (as to SMF), accompanied by payment of the applicable filing fees, the security
interest granted in the Personal Property Collateral pursuant to the Security Agreement will be
perfected, to the extent such security interest may be perfected solely by filing one or more
financing statements in the central UCC filing office of the jurisdiction in which each of the Loan
Parties is organized.

9. The Security Agreement creates in favor of the Collateral Agent, for the benefit of the Secured
Parties, valid and enforceable security interest in the Equity Interests of STI and SCS owned by
the Borrower and in the Equity Interests of SMF owned by STI. No election has been made by SMF to
treat its Equity Interests as securities under Article 8 of the UCC. The Equity Interests in SMF
are uncertificated. Accordingly, the filing of the financing statement in the UCC records of the
Delaware Secretary of State, accompanied by payment of the applicable filing fees, is sufficient to
perfect the Collateral Agent’s security interest pursuant to the UCC in the Equity Interests of SMF
owned by STI. Upon delivery of the stock certificates evidencing the outstanding Equity Interests
in each of SCS and STI, accompanied by stock powers executed in blank, the Collateral Agent will
have a perfected security interest in and control over the Equity Interests in each of SCS and STI.

10. To counsel’s knowledge and except as set forth in filings made by the Borrower with the SEC,
there are no actions, suits or proceedings by or before any court, arbitrator or governmental
agency or authority pending or threatened against or affecting either of the Loan Parties (a) as to
which there is a reasonable possibility of an adverse determination and which, if adversely
determined, could reasonably be expected, individually or in the aggregate, to have a material
adverse effect, or (b) that involve the Credit Agreement, any Loan Document or the transactions
contemplated thereby.

11. The Borrower is not an “investment company” as defined in, or subject to regulation under, the
Investment Company Act of 1940.
