Inc. (the &#147;<U>Company</U>&#148;) entered into the Second Amendment (the &#147;<U>Amendment</U>&#148;) to Fourth Amended and Restated Credit Agreement among the Company and certain of the Company&#146;s subsidiaries, as Borrowers, the
Company&#146;s U.S. subsidiaries party thereto, as Guarantors, the lenders party thereto, Bank of America, N.A., as Administrative Agent, and the Swing Line Lenders and L/C Issuers party thereto. The Amendment amends the Fourth Amended and Restated
Credit Agreement, dated as of December&nbsp;18, 2015, as amended, among such parties (as amended by the Amendment, the &#147;<U>Credit Agreement</U>&#148;). </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Amendment, among other things, extended the maturity date of the Company&#146;s $1.810 billion senior secured revolving credit facility
from December&nbsp;18, 2020 to October&nbsp;31, 2022 and modified the applicable rate for certain borrowings and letters of credit under the facility. Pursuant to the Amendment, amounts borrowed under the Credit Agreement in U.S. dollars will bear
interest, at the Company&#146;s option, at a rate equal to either (a)&nbsp;the Eurocurrency Rate (as defined in the Credit Agreement) plus 1.125% to 2.000%, as determined based on the Company&#146;s Consolidated Leverage Ratio (as described below),
or (b)&nbsp;the Base Rate (as described below) plus 0.125% to 1.000%, as determined based on the Company&#146;s Consolidated Leverage Ratio. Amounts borrowed as revolving loans under the Credit Agreement in any currency other than U.S. dollars will
bear interest at a rate equal to the Eurocurrency Rate plus 1.125% to 2.000%, as determined based on the Company&#146;s Consolidated Leverage Ratio. Standby or commercial letters of credit issued under the Credit Agreement will be subject to a
letter of credit fee of 1.125% to 2.000%, based on the Company&#146;s Consolidated Leverage Ratio, and Performance Letters of Credit (as defined in the Credit Agreement) issued under the Credit Agreement in support of certain contractual obligations
will be subject to a letter of credit fee of 0.675% to 1.150%, based on the Company&#146;s Consolidated Leverage Ratio. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Consolidated
Leverage Ratio is the ratio of the Company&#146;s total funded debt to Consolidated EBITDA (as defined in the Credit Agreement). For purposes of calculating the Consolidated Leverage Ratio, total funded debt is reduced by available cash and Cash
Equivalents (as defined in the Credit Agreement) in excess of $25.0 million. The Base Rate equals the highest of (i)&nbsp;the Federal Funds Rate (as defined in the Credit Agreement) plus 1/2 of 1%, (ii)&nbsp;Bank of America&#146;s prime rate and
(iii)&nbsp;the Eurocurrency Rate plus 1.00%. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">As of the closing of the Amendment on October&nbsp;31, 2017, the Company had approximately
$384.9 million of outstanding letters of credit and bank guarantees issued under the Credit Agreement and $685.0 million of outstanding revolving loans. The remaining $740.1 million commitment was available for revolving loans or issuing new letters
of credit and bank guarantees. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Merrill Lynch, Pierce, Fenner&nbsp;&amp; Smith Incorporated and JPMorgan Chase Bank, which acted as
Arrangers (as defined in the Credit Agreement) for the Amendment, and some of the other lenders under the Credit Agreement and their respective affiliates, have provided financial advisory and investment banking services to the Company and its
subsidiaries for which they have received customary fees. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The foregoing description of the Amendment is qualified in its entirety by
