the Loans outstanding as of such Scheduled Payment Date minus (y) the Permitted
Interim Outstanding Principal Amount applicable to such Scheduled Payment Date
(either such amount, a ‘Preliminary Interim Repayment’). On the third Scheduled
Payment Date, the Borrower shall repay to the Collection Account, and there
shall become due and payable, the remainder of the aggregate outstanding
principal amount of the Loans and all accrued interest thereon (including all
Aggregate Default Interest and all accrued interest thereon) (such amount, the
‘Final Interim Repayment’), and the Loans of each Lender shall be ratably
repaid. In the event that any Interim Repayment is not paid when due, the Agent
may, with the prior written consent of each Lender (which such consent shall be
in the sole discretion of each such Lender) extend any such payment date on
terms satisfactory to such Lenders (in their sole discretion); provided that,

of the Collateral in the amount and in the manner specified by the Agent, and
upon any such sale the Borrower shall prepay a portion of the principal amount
of the outstanding Loans in an aggregate amount equal to the Net Cash Proceeds
for each Railcar so sold. For the avoidance of doubt, the failure of the Agent
or the Lenders to give or make any such direction or request, as applicable, on
the date that any Interim Repayment was not paid when due shall not waive their
respective rights to give such direction at any future time that such amount
continues to be unpaid.”

the words “or Section 2.07(b)(v), as applicable,” immediately after the words

part of an Interim Repayment due before but not on or after the Legal Final
Maturity Date)” immediately after the words “shall occur” and immediately before

months of receiving direction from the Agent to make any such Asset Disposition,
in each case in accordance with the terms set forth in such direction.”

“(a) in the case of this Agreement, upon the Agent (x) requesting from each
Rating Agency (if any) a determination whether, as a result of any such
amendment (except for changes to the definition of “Committed Amount,”
“Scheduled Payment Date” or the dates on which any Interim Repayment is due
pursuant to Section 2.06, or other changes or agreements in respect of the
subject matter herein which are, in the judgment of the Agent, ministerial or
address mechanical matters not raising any substantive credit-related concerns,
including in respect of such repayment and release matters associated with Asset
Dispositions under Section 7.05), it would cause the rating of the Notes to be
reduced or withdrawn, and providing notice of such determination to the Borrower
and each of the Lenders or (y) giving written notice to each Rating Agency (if
