<p style="margin:0in 0in .0001pt;text-indent:27.35pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On April&nbsp;24, 2013, AAR CORP. (the &#147;Company&#148;) entered into an amendment (the &#147;Amendment&#148;) to its credit agreement dated April&nbsp;12, 2011, as amended, with various financial institutions, as lenders and Bank of America, N.A., as administrative agent for the lenders (the &#147;Credit Agreement&#148;).</font></p>
<p style="margin:0in 0in .0001pt;text-indent:27.5pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:27.35pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">As previously reported, the Company sold an additional $150,000,000 of 7&#188;% Senior Notes due 2022 on April&nbsp;15, 2013.&#160; Under the terms of the Credit Agreement as in effect prior to the Amendment, the Company was required to use the proceeds of the sale to reduce the revolving credit commitment under the Credit Agreement, but not below $500,000,000.&#160; The Amendment reduces the aggregate revolving credit commitment amount under the Credit Agreement by a further $25,000,000 to $475,000,000, reflecting the fact that the principal amount of notes sold represents an increase of $25,000,000 over the amount originally proposed.&#160; The Amendment also extends the maturity of the Credit Agreement by approximately two years to April&nbsp;24, 2018.&#160; The Amendment also deleted the minimum net worth covenant, together with the requirement that the Company make certain mandatory pre-payments, upon the issuance of certain other debt. The Credit Agreement was previously amended on April&nbsp;8, 2013 to permit AAR&#146;s subsidiaries to guarantee any unsecured debt AAR may incur, including the additional 7&#188;% Senior Notes due 2022 issued on April&nbsp;15, 2013. Except as specifically amended and modified by the Amendment, the terms and conditions of the Credit Agreement remain in effect.</font></p>

Item 1.01.
Entry into a Material Definitive Agreement.
On April 24, 2013, AAR CORP. (the "Company") entered into an amendment (the "Amendment") to its credit agreement dated April 12, 2011, as amended, with various financial institutions, as lenders and Bank of America, N.A., as administrative agent for the lenders (the "Credit Agreement").
As previously reported, the Company sold an additional $150,000,000 of 7¼% Senior Notes due 2022 on April 15, 2013.  Under the terms of the Credit Agreement as in effect prior to the Amendment, the Company was required to use the proceeds of the sale to reduce the revolving credit commitment under the Credit Agreement, but not below $500,000,000.  The Amendment reduces the aggregate revolving credit commitment amount under the Credit Agreement by a further $25,000,000 to $475,000,000, reflecting the fact that the principal amount of notes sold represents an increase of $25,000,000 over the amount originally proposed.  The Amendment also extends the maturity of the Credit Agreement by approximately two years to April 24, 2018.  The Amendment also deleted the minimum net worth covenant, together with the requirement that the Company make certain mandatory pre-payments, upon the issuance of certain other debt. The Credit Agreement was previously amended on April 8, 2013 to permit AAR's subsidiaries to guarantee any unsecured debt AAR may incur, including the additional 7¼% Senior Notes due 2022 issued on April 15, 2013. Except as specifically amended and modified by the Amendment, the terms and conditions of the Credit Agreement remain in effect.
The foregoing description of the Amendment is qualified in its entirety by reference to the full text of the Amendment and the Credit Agreement.  A copy of the Amendment is filed as Exhibit 10.1 and incorporated herein by reference
