  decision to invest in our notes. The risks and uncertainties described below and in the documents incorporated by reference are not the only ones facing our company. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also materially adversely affect our business and

<P style="margin:6.3mm 0 0; "><FONT style="font-family:serif; font-size:3.8mm; "><B>Our outstanding debt may impair our financial and operating flexibility.</B></FONT></P>
<P style="text-indent:7mm; margin:2.1mm 0 0; "><FONT style="font-family:serif; font-size:3.8mm; ">As
    of September 30, 2009, after giving effect to this offering and the anticipated
    use of the net proceeds therefrom and assuming the tender of all the notes
    in our concurrent tender offer (as if all of the foregoing had occurred on
    that date), we would have had approximately $3.2 billion of debt outstanding,
    with $750 million of available capacity under our senior unsecured revolving
    credit facility and $400 million of available capacity under our secured
    receivables credit facility which matures on December 11, 2009. Except for
    outstanding letters of credit, bank guarantees and operating leases, we do
    not have any off-balance sheet financing arrangements in place or available.
    See Note 9 to our Consolidated Financial Statements in our Annual Report
    on Form 10-K for the year ended December 31, 2008 and Note 5 to our Interim
    Consolidated Financial Statements in our Quarterly Report on Form 10-Q for
    the quarter ended September&nbsp;30, 2009 for further details
  related to our outstanding debt. See Note 4 to our Interim Consolidated Financial
    Statements in our Quarterly Report on Form 10-Q for the quarter ended September
    30, 2009 for further details related to our use of derivative financial instruments
    to manage our exposure to market risks for changes in interest rates and
    foreign currency. Our debt agreements contain various restrictive covenants.
    These restrictions could limit our ability to use operating cash flow in
    other areas of our business because we must use a portion of these funds
    to make principal and interest payments on our debt.</FONT></P>
<P style="text-indent:7mm; margin:2.1mm 0 0; "><FONT style="font-family:serif; font-size:3.8mm; ">Our debt portfolio is sensitive to changes in interest rates. As of September 30, 2009, after giving effect to this offering and the anticipated use of the net proceeds therefrom and assuming the tender of all the notes in our concurrent tender offer (as if all the foregoing had occurred on that date) we would have had
  approximately $1.2 billion of floating rate debt. In addition, any future borrowings by us under our senior unsecured revolving credit facility, the secured receivables credit facility or the issuance of other floating rate debt will expose us to additional interest rate risk. Interest on our secured receivables credit facility is based on
  rates that are intended to approximate commercial paper rates for highly-rated issuers. Interest rates on our senior unsecured revolving credit facility and term loan are also subject to a pricing schedule that fluctuates based on changes in our credit rating.</FONT></P>
<P style="text-indent:7mm; margin:2.1mm 0 0; "><FONT style="font-family:serif; font-size:3.8mm; ">We have obtained ratings on our debt from Standard &amp; Poor&#146;s Rating Services, Moody&#146;s Investors Service, Inc. and Fitch Ratings. There can be no assurance that any rating so assigned will remain for any given period of time or that a rating will not be lowered or withdrawn entirely by a rating agency if in that rating
  agency&#146;s judgment future circumstances relating to the basis of the rating, such as adverse changes in our company or our industry, so warrant. If such ratings are lowered, the borrowing costs on our senior unsecured revolving credit facility, secured receivables facility and term loan would increase. Changes in our credit ratings,
  however, do not require repayment or acceleration of any of our debt.</FONT></P>
<P style="text-indent:7mm; margin:2.1mm 0 0; "><FONT style="font-family:serif; font-size:3.8mm; ">We or our subsidiaries may incur additional indebtedness in the future. The notes offered hereby do not limit our or our subsidiary guarantors&#146; ability to incur unsecured indebtedness. Our ability to make principal and interest payments will depend on our ability to generate cash in the future. If we incur additional debt, a
  greater portion of our cash flows may be needed to satisfy our debt service obligations and if we do not generate sufficient cash to meet our debt service requirements, we may need to seek additional financing. In this case, it may be more difficult, or we may be unable, to obtain financing on terms that are acceptable to us. As
  a result, we would be more vulnerable to general adverse economic, industry and capital markets conditions as well as the other risks associated with indebtedness.</FONT></P>

The discussion is based upon the Internal Revenue Code of 1986, as amended (the
  &#147;Code&#148;), United States Treasury Regulations issued thereunder, Internal Revenue Service (&#147;IRS&#148;) rulings and pronouncements and judicial decisions now in effect, all of which are subject to change at any time. Any such change may be applied retroactively in a manner that could adversely affect a beneficial owner of the Notes.
  This discussion does not address all of the United States federal income tax consequences that may be relevant to a beneficial owner of the Notes in light of its particular circumstances or to beneficial owners of the Notes subject to special rules, such as certain financial institutions, U.S. expatriates, insurance companies, dealers
  in securities or foreign currencies, traders in securities, &#147;United States Holders&#148; (as defined below) whose functional currency is not the U.S. dollar, partnerships and other pass through entities and their beneficial owners, tax-exempt organizations and persons holding the notes as part of a &#147;straddle,&#148; &#147;hedge,&#148; &#147;conversion
  transaction&#148; or other integrated transaction. In addition, this discussion is limited to beneficial owners of the Notes that purchase the Notes for cash in this offering at a price equal to their &#147;issue price&#148; within the meaning of Section 1273 of the Code. Moreover, the effect of any applicable state, local or foreign tax laws and any
  as part of United States federal tax law other than law pertaining to income taxation, is not discussed in this summary. The discussion deals only with Notes held as &#147;capital assets&#148; within the meaning of Section 1221 of the Code.</FONT></P>
