Although merger integration and operational challenges have slowed the performance of our North American business, we are addressing these issues and expect to deliver improvements in revenues and margins in this business by the last half of 2008. We recently transferred key management team members to our North American organization, bringing valuable additional resources and experience to help us complete our merger integration, further our service excellence initiative, and resume growth in our North American business."

(1) Management believes disclosure of EBITDA, as further adjusted, and
 Gross Margin, as adjusted, both non-GAAP measures, provides useful
 information to investors because, when viewed with our GAAP results
 and accompanying reconciliations, they provide a more complete
 understanding of our performance than GAAP results alone. Management
 uses EBITDA, as further adjusted, and Gross Margin, as adjusted, as
 supplemental measures to review current period operating performance,
 comparability measures and performance measures for period to period
 comparisons. In addition, EBITDA, as further adjusted, is used by
 management as a valuation measure.
(2) Distributable cash flow, a non-GAAP measure, is a significant
 liquidity metric used by management to compare basic cash flows
 generated by us to the cash distributions we expect to pay our
 partners. Using this metric, management can quickly compute the
 coverage ratio of estimated cash flows to planned cash distributions.
