| (1) | The                dividend yield is based on our historical experience and future                expectation of dividend payouts.  The increase in the dividend                yield in the 2007 period resulted from the Company increasing the                dividend                payment during the 2007 period from two cents per share to three                cents per                share. |

| (2) | We                analyzed the volatility of our stock using historical data from January                1,                2003 through the end of the most recent period to estimate the expected                volatility.                                                                                                                                                                                      |

All statements, other than      statements of historical fact, are statements that could be deemed      forward-looking statements, including without limitation: any projections of      revenues, earnings, cash flows, capital expenditures, or other financial items;      any statement of plans, strategies, and objectives of management for future      operations; any statements concerning proposed acquisition plans, new services,      or developments; any statements regarding future economic conditions or      performance; and any statements of belief and any statement of assumptions      underlying any of the foregoing.  Words such as "believe," "may,"      "could," "expects," "hopes," "anticipates," and "likely," and variations of      these words, or similar expressions, are intended to identify such      forward-looking statements. Actual events or results could differ materially      from those discussed in forward-looking statements. Factors that could cause      or      contribute to such differences include, but are not limited to, those discussed      in the section entitled "Item 1A. Risk Factors," set forth in our form      10-K for the year ended December 31, 2006, as supplemented in Part      II  below.*

The Company expressly disclaims any      obligation or undertaking to release publicly any updates or revisions to any      forward-looking statements contained herein to reflect any change in the      Company's expectations with regard thereto or any change in the events,      conditions, or circumstances on which any such statement is      based.*
