From time to time, we make presentations to investors, analysts, the media and other persons interested in our company. The present form of presentation that we are using is attached. The contents of this presentation include forward-looking statements that were and are made in express reliance on the safe harbor provisions contained in Section 21E of the Exchange Act and Section 27A of the Securities Act. Such statements include, without limitation, statements relating to results deemed to be achievable by our management in future periods, as well as with respect to trends in sales performance, gross margin, selling, general and administrative costs, market growth, the competitive environment, and other factors affecting future sales, operating results, and capital requirements. Sales and operating results trends are also affected by many other factors, including, among others, world and national political events, general economic conditions which recently have been weak, the effectiveness of our promotion and marketing strategies, and competitive factors applicable to our corporate and consumer markets.

The presentation material also includes selected financial measures that constitute “non-GAAP” data under the Securities and Exchange Commission’s rules, particularly including our calculation of earnings before interest, taxes, depreciation and amortization, or Ebitda.

The statements furnished in this presentation must be viewed in context and in light of the risks described above and under the caption “Risk Factors” contained in our most recent reports on Form 6-K or 20-F filed with the SEC. In light of these risks, there can be no assurance that the forward-looking statements furnished in this presentation will in fact be realized. The statements made in this presentation speak as of its date only, and it should not be assumed that the statements made herein or therein remain accurate as of any future date.
