ITEM 4    PURPOSE OF TRANSACTION

          Transactions for the purchase of shares of Class A Common Stock (the
          "Shares") of Swisher International Group Inc. (the "Company") were
          executed by Zweig-DiMenna Special Opportunities, L.P., Zweig-DiMenna
          International Limited, the ZDIM Account and the Gotham Account (the
          "Investors") for investment purposes only. The Investors continue to
          evaluate their ownership and voting position in the Company and may
          consider the following future courses of action: (i) continuing to
          hold the Shares for investment; (ii) disposing of all or a portion of
          the Shares in open market sales or in privately negotiated
          transactions; or (iii) acquiring additional shares of common stock in
          the open market or in privately negotiated transactions. The Investors
          have not as yet determined which of the courses of action specified in
          this paragraph they may ultimately take. The Investors' future actions
          with regard to this investment in the Company are dependent upon their
          evaluation of a variety of circumstances affecting the Company in the
          future, including the market price of the Company's common stock, the
          Company's prospects and their own portfolios.

          Other than as described above, the Investors do not have any present
          plans or proposals which relate to or would result in any of the
          following (although they reserve the right to develop such plans or
          proposals): a) the acquisition by any person of additional securities
          of the Company, or the disposition of securities of the Company; b) an
          extraordinary corporate transaction, such as a merger, reorganization
          or liquidation, involving the Company or any of its subsidiaries; c) a
          sale or transfer of a material amount of assets of the Company or any
          of its subsidiaries; d) any change in the present board of directors
          or management of the Company, including any plans or proposals to
          change the number or term of directors or to fill any existing
          vacancies on the board; e) any material change in the present
          capitalization or dividend policy of the Company; f) any other
          material change in the Company's business or corporate structure; g)
          changes in the Company's charter, by-laws or instruments corresponding
          thereto or other actions which may impede the acquisition or control
          of the Company by any person; h) causing a class of securities of the
          Company to be delisted from a national securities exchange or to cease
          to be authorized to be quoted in an inter-dealer quotation system of a
          registered national securities association; i) a class of equity
          securities of the Company becoming eligible
