Pruco Life Insurance Company

Each Prudential Affiliate (as defined herein)

c/o Prudential Capital Group

Dallas, Texas 75201

Ladies and Gentlemen:

We refer to the Master Shelf Agreement, dated as of September 20, 2002 (the
“Agreement”), among the undersigned, SCS Transportation, Inc. (the “Company”),
Prudential, PICA, Pruco Life Insurance Company, Reliastar Life Insurance Company
and Southland Life Insurance Company. Unless otherwise defined herein, the terms
defined in the Agreement shall be used herein as therein defined.

The Company desires to (i) increase the amount of the Notes available to be
issued under the Agreement to an aggregate principal amount of $150,000,000,
(ii) extend the Issuance Period until April 21, 2008 and (iii) amend certain
provisions of the Agreement. Prudential and the holders of Notes have agreed to
permit the Facility to be increased to $150,000,000. However, PICA and its
Subsidiaries and other corporations owned by Prudential Financial, Inc. may only
purchase and hold Notes in an aggregate principal amount not to exceed
$100,000,000. Amounts in excess of $100,000,000 of Accepted Notes will be
purchased by Prudential Affiliates that are managed accounts managed by
Prudential.

Therefore, Prudential, the holders of the Notes and the Company, in
consideration of the mutual promises and agreements set forth herein and in the
Agreement, agree as follows:

1

1. Amendments.

(a) Paragraph 1. Authorization of Notes. Paragraph 1 of the Agreement is amended
by deleting the amount “$125,000,000” contained therein and substituting
therefore the amount “$150,000,000.”

(b) Paragraph 2A. Facility. Paragraph 2A of the Agreement is amended in full to
read as follows:

"(i) Facility. Prudential is willing to consider, in its sole discretion and
within limits which may be authorized for purchase by Prudential Affiliates from
time to time, the purchase of $150,000,000 of the total amount of authorized
Notes pursuant to this Agreement. The willingness of Prudential to consider such
purchase of Notes is herein called the “Facility”. At any time, subject to the
additional limitations in Paragraph 2A(ii), the aggregate principal amount of
Notes stated in Paragraph 1A, minus the aggregate principal amount of Notes
purchased and sold pursuant to this Agreement prior to such time, minus the
aggregate principal amount of Accepted Notes which have not yet been purchased
and sold hereunder prior to such time is herein called the “Available Facility
Amount” at such time. NOTWITHSTANDING THE WILLINGNESS OF PRUDENTIAL TO CONSIDER
PURCHASES OF NOTES, THIS AGREEMENT IS ENTERED INTO ON THE EXPRESS UNDERSTANDING
THAT NEITHER PRUDENTIAL NOR ANY PRUDENTIAL AFFILIATE SHALL BE OBLIGATED TO MAKE
OR ACCEPT OFFERS TO PURCHASE NOTES, OR TO QUOTE RATES, SPREADS OR OTHER TERMS
WITH RESPECT TO SPECIFIC PURCHASES OF NOTES, AND THE FACILITY SHALL IN NO WAY BE
CONSTRUED AS A COMMITMENT BY PRUDENTIAL OR ANY PRUDENTIAL AFFILIATE.

(ii) Limitation on Facility. Notwithstanding anything in paragraph 2A(i), the
Company may not request the issuance of Notes, and neither Prudential nor any
other Prudential Financial Entity shall be required to purchase Notes pursuant
to the Facility if, after the issuance of such Notes, the aggregate amount of
SCS Exposure would exceed $100,000,000. If the purchase of any Accepted Note
would cause the aggregate amount of SCS Exposure to exceed $100,000,000, such
Accepted Notes would be purchased by Prudential Affiliates that are not
Prudential Financial Entities.”

(c) Paragraph 2B. Issuance Period. Paragraph 2B of the Agreement is amended in
full to read as follows:

“2B. Issuance Period. Notes may be issued and sold pursuant to this Agreement
until the earlier of (i) April 21, 2008 (or if such day is not a Business Day,
the Business Day next preceding such day) and (ii) the thirtieth day after
Prudential shall have given to the Company, or the Company shall have given to
Prudential, written notice stating that it elects to terminate the issuance and
sale of Notes pursuant to this Agreement (or if such thirtieth day is not a
Business Day, the Business Day next preceding such thirtieth day). The period
during which Notes may be issued and sold pursuant to this Agreement is herein
called the ‘Issuance Period‘.”

(d) Paragraph 5A. Financial Statements; Notice of Defaults. Paragraph 5A of the
Agreement is amended (I) by amending clause (i) thereof to delete the word
“GAAP” at the end thereof and replace it with the phrase “then current SEC and
GAAP standards” and (II) by amending clause (ii) thereof to delete the word
“GAAP” at the end thereof and replace it with the phrase “then current SEC and
GAAP standards.”

Agreement is amended in its entirety to read as follows:

“6A(1). Total Indebtedness to EBITDAR Ratio. The Company will not permit, on any

the Company or any Subsidiary through purchase, merger or consolidation or
otherwise for each consecutive fiscal quarter or portion thereof from the date
12 months prior to the date of termination to the applicable acquisition less

consecutive fiscal quarter or portion thereof from the date 12 months prior to
the date of determination to the applicable disposition to be greater than 2.75
to 1.00.”

(f) Paragraph 6A(2). Adjusted Total Indebtedness to EBITDAR Ratio.
Paragraph 6A(2) of the Amendment is amended in its entirety to read as follows:

“6A(2). Adjusted Total Indebtedness to EBITDAR Ratio. The Company will not

to (ii)(a) EBITDAR of the Company for the period of four consecutive fiscal
quarters most recently ended on or immediately preceding the date of
determination and (b) without duplication, EBITDAR for any Person acquired by
the Company or any Subsidiary through purchase, merger or consolidation or

consecutive fiscal quarter or portion thereof from the date 12 months prior to
the date of determination to the applicable disposition to be greater than 3.00
to 1.00.”

amending clause (viii) thereof in its entirety to read as follows:
