GATX Corporation

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We have audited the accompanying statements of net assets available for
benefits of the GATX Corporation Salaried Employees Retirement Savings Plan as
of December&nbsp;31, 2010 and 2009, and the related statements of changes in net
assets available for benefits for the years then ended. These financial
statements are the responsibility of the Plan&#146;s management. Our responsibility
is to express an opinion on these financial statements based on our audits.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. We were not engaged to
perform an audit of the Plan&#146;s internal control over financial reporting. Our
audits included consideration of internal control over financial reporting as a
basis for designing audit procedures that are appropriate in the circumstances,
but not for the purpose of expressing an opinion on the effectiveness of the
Plan&#146;s internal control over financial reporting. Accordingly, we express no
such opinion. An audit also includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for our opinion.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan at
December&nbsp;31, 2010 and 2009, and the changes in its net assets available for
benefits for the years then ended, in conformity with US generally accepted
accounting principles.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Our audits were performed for the purpose of forming an opinion on the
financial statements taken as a whole. The accompanying supplemental schedule
of assets (held at end of year) as of December&nbsp;31, 2010, is presented for
purposes of additional analysis and is not a required part of the financial
statements but is supplementary information required by the Department of
Labor&#146;s Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. This supplemental schedule is the
responsibility of the Plan&#146;s management. The supplemental schedule has been
subjected to the auditing procedures applied in our audits of the financial
statements and, in our opinion, is fairly stated in all material respects in
relation to the financial statements taken as a whole.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The following description of the GATX Corporation (GATX or the Company) Salaried Employees
Retirement Savings Plan (the Plan) provides only general information. Participants should refer to
the plan document for a more complete description of the Plan&#146;s provisions.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>General</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Plan is a defined-contribution plan established on July&nbsp;1, 1965, for salaried employees of GATX
and each of its domestic subsidiaries. The Plan is subject to the provisions of the Employee
Retirement Income Security Act of 1974, as amended (ERISA). Fidelity Management Trust Company has
been appointed fiduciary of the Plan and also serves as the record keeper to maintain the
individual accounts of each Plan participant.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Contributions</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Each year, participants may make basic contributions of 1% to 50% of eligible pretax compensation,
as defined in the Plan, and participants who have attained the age of 50 before the close of the
plan year may make catch-up contributions of 1% to 25% of eligible pretax compensation.
Participants may also contribute amounts representing distributions from other qualified
defined-benefit or defined-contribution plans. Participant contributions are made through payroll
deductions and are recorded in the period the deductions are made.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">After a participant completes six months of service, the Company may contribute on behalf of the
participant a matching contribution of $0.50 for each $1.00 contributed by the participant, up to
6% of the participant&#146;s eligible compensation. At its discretion, the Company may suspend matching
contributions or make additional matching contributions for eligible participants. All
contributions are made in cash and are deposited semimonthly. All contributions are subject to

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In January&nbsp;2010, the Financial Accounting Standards Board (FASB)&nbsp;issued Accounting Standards Update
2010-06, <I>Improving Disclosures about Fair Value Measurements, </I>(ASU 2010-06). ASU 2010-06 amended
Accounting Standards Codification (ASC)&nbsp;Topic 820 to clarify certain existing fair value
disclosures and require a number of additional disclosures. The guidance in ASU 2010-06 clarified
that disclosures should be presented separately for each &#147;class&#148; of assets and liabilities measured
at fair value and provided guidance on how to determine the appropriate classes of assets and
liabilities to be presented.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">ASU 2010-06 also clarified the requirement for entities to disclose information about both the
valuation techniques and inputs used in estimating Level 2 and Level 3 fair value measurements. In
addition, ASU 2010-06 introduced new requirements to disclose the amounts (on a gross basis) and
reasons for any significant transfers between Levels 1, 2 and 3 of the fair value hierarchy and
present information regarding the purchases, sales, issuances and settlements of Level 3 assets and
liabilities on a gross basis.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In September&nbsp;2010, the FASB issued Accounting Standards Update 2010-25, <I>Reporting Loans to
Participants by Defined Contribution Pension Plans, </I>(ASU 2010-25). ASU 2010-25 requires participant
loans to be measured at their unpaid principal balance plus any accrued but unpaid interest and
classified as notes receivable from participants.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Previously, loans were measured at fair value and classified as investments. ASU 2010-25 is
effective for the fiscal years ending after December&nbsp;15, 2010, and is required to be applied
retrospectively.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The adoption of ASU 2010-25 did not change the value of participant loans from the amount
previously reported as of December&nbsp;31, 2009. Participant loans have been reclassified to notes
receivable from participants as of December&nbsp;31, 2009.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Notes receivable from participants represent participant loans that are recorded at their unpaid
principal balance plus any accrued but unpaid interest. Interest income on notes receivable from
participants is recorded when it is earned. Related fees are recorded as administrative expenses
and are expensed when they are incurred. No allowance for credit losses has been recorded as of
December&nbsp;31, 2010 or 2009. If a participant ceases to make loan repayments and the Plan
administrator deems the participant loan to be a distribution, the participant loan balance is
reduced and a benefit payment is recorded.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Use of Estimates</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The preparation of financial statements in conformity with GAAP requires management to make
estimates that affect the amounts reported in the financial statements, accompanying notes and
supplemental schedule. Actual results could differ from those estimates.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Investments held by the Plan are stated at fair value. Fair value is defined as the price that
would be received to sell an asset or paid to transfer a liability in an orderly transaction
between market participants at the measurement date. See Note 4 for further discussion and
disclosures related to fair value measurements.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded
as earned. Dividends are recorded on the ex-dividend date. Investment gains and losses include
those that are realized and unrealized.

risks such as interest rate, market volatility and credit risk. Due to the level of risk associated

judgment about the reliability of the inputs used in the fair value measurement.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Level 1 &#151; Measurements for which quoted prices are available in active markets for identical assets
or liabilities.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Level 2 &#151; Measurements containing pricing inputs other than quoted prices in active markets, such
as quoted prices for similar assets or liabilities; quoted prices in markets that are not active;
or other inputs that are observable or can be corroborated by observable market data for
substantially the full term of the assets or liabilities.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Level 3 &#151; Measurements containing unobservable inputs that are supported by little or no market
activity and that are significant to the fair value of the assets or liabilities. Level 3
measurement techniques typically include pricing models and discounted cash flow methodologies and
significant judgment is required.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt">The following is a description of the valuation techniques and inputs used as of December&nbsp;31, 2010
and 2009:
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><I>Mutual funds</I>: Valued at quoted market prices, which represent the net asset values (NAV)&nbsp;of shares
held at year-end.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><I>GATX Stock Fund</I>: Tracked on a unitized basis and consists of shares of GATX common stock and cash
sufficient to meet the fund&#146;s daily cash needs. Unitizing the GATX Stock Fund allows for daily
trades into and out of the fund. The value of a unit reflects the combined market value of GATX
common stock, which is traded on an active exchange, and the cash investments, which are held in
the Fidelity Institutional Money Market. At December&nbsp;31, 2010 and 2009, the value of a unit was
$23.47 and $18.47, respectively.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><I>Collective trusts (excluding the Fidelity MIP fund)</I>: Valued based on the closing NAV prices quoted
by the funds. The NAV represents the unitized fair values of the underlying securities held by the
trusts, which are traded on an active exchange market. There are no unfunded commitments,
restrictions on redemption frequency or advance notice periods required for redemption for any of
the collective trusts.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><I>Fidelity MIP Fund</I>: Contains investments in fully benefit-responsive insurance contracts that
provide that the Plan may make withdrawals at contract value for benefit-responsive requirements.
Participant-directed redemptions have no restrictions; however, the Plan is required to provide a
one year redemption notice to liquidate their entire share in the fund. The Fidelity MIP Fund value
is determined by the fund manager using a pricing model with inputs (such as yield curves and
credit spreads) that are observable or can be corroborated by observable market data for
substantially the full term of the assets.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Plan&#146;s interest in the Fidelity MIP Fund is presented at fair value on the statements of assets

</DIV>
<!-- xbrl,body -->

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Plan has received a determination letter from the Internal Revenue Service dated July&nbsp;31, 2002,
stating that the Plan is qualified under Section 401(a) of the Code, and therefore, the related
trust is exempt from taxation. Subsequent to this determination, the Plan was amended. Once
qualified, the Plan is required to operate in conformity with the Code to maintain its
qualification. The plan administrator believes that the Plan is being operated in compliance with
the applicable requirements of the Code and, therefore, believes that the Plan, as amended, is
qualified and the related trust is tax-exempt.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">GAAP requires Plan management to evaluate uncertain tax positions taken by the Plan. The financial
statement effects of a tax position are recognized when the position is more likely than not, based
on the technical merits, to be sustained upon examination by the IRS. The Plan administrator has
analyzed the tax positions taken by the Plan, and has concluded that as of December&nbsp;31, 2010, there
are no uncertain positions taken or expected to be taken. The Plan has recognized no interest or
penalties related to uncertain tax positions. The Plan is subject to routine audits by taxing
jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan
administrator believes it is no longer subject to income tax examinations for years prior to 2007.

</DIV>
<!-- xbrl,body -->

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Plan holds units of collective trusts and the Fidelity Institutional Money Market which are
managed by Fidelity Management Trust Company, the record keeper of the Plan. The Plan also invests
in the common stock of the Company. These transactions qualify as party-in-interest transactions;
however, they are exempt from the prohibited transactions rules under ERISA.
