SCHEDULE 13D

Page 4 of 6

 

 

Mr. Lappe acquired the shares of the Common Stock reported in this Schedule 13D in the Spin-Off and holds such shares for investment purposes and intends to review such investment in the Issuer on a continuing basis. Consistent with such purposes, Mr. Lappe may engage in communications with, without limitation, one or more stockholders of the Issuer, management of the Issuer and/or one or more members of the board of directors of the Issuer and may make suggestions concerning the Issuer’s operations, prospects, business and financial strategies, strategic transactions, assets and liabilities, business and financing alternatives, the composition of the board of directors of the Issuer and such other matters as Mr. Lappe may deem relevant to his investment in the Issuer. Mr. Lappe expects that he will, from time to time, review his investment position in the shares of the Common Stock or the Issuer and may, depending on the Issuer’s performance and other market conditions, increase or decrease his investment position in the Common Stock. Mr. Lappe may, from time to time, make additional purchases of shares of the Common Stock either in the open market or in privately negotiated transactions, depending upon his evaluation of the Issuer’s business, prospects, financial condition and results of operations, the market for the Common Stock, other opportunities available to Mr. Lappe, general economic conditions, stock market conditions and other factors. Depending upon the factors noted above, Mr. Lappe may also decide to hold or dispose of all or part of his investment in the Common Stock and/or enter into derivative transactions with institutional counterparties with respect to the Issuer’s securities, including the Common Stock.

Any actions Mr. Lappe might undertake may be made at any time and from time to time without prior notice and will be dependent upon Mr. Lappe’s review of numerous factors, including, but not limited to: an ongoing evaluation of the Issuer’s business, financial condition, operations and prospects; price levels of the Issuer’s securities; general market, industry and economic conditions; the relative attractiveness of alternative business and investment opportunities; and other future developments. Mr. Lappe reserves the right to change his intentions, or to formulate plans and proposals, with respect to any or all of the matters described in this paragraph, subject to applicable law and regulations.

Separately from the acquisition of the Common Stock for investment purposes, Mr. Lappe serves as the Chief Executive Officer, President and Chairman of the board of directors of the Issuer and therefore regularly engages in discussions with management of the Issuer, the board of directors of the Issuer, other shareholders of the Issuer and other relevant parties, which discussions my include matters ranging from the operations and conduct of the Issuer’s business to considering or exploring extraordinary corporate transactions including the events listed in Items 4(a) through 4(j) of Schedule 14D.

Except as set forth in this Item 4 or Item 6 below, Mr. Lappe has no present plans or proposals that relate to, or that would result in, any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D under the Securities Exchange Act of 1934, as amended.

Item 5.
