#### Federal Income Tax Consequences
The Stock Purchase and Matching Plan is not intended to qualify as an “employee stock purchase plan” under Section 423 of the Code. Accordingly, certain tax benefits available to participants in a Section 423 plan are not available under our Stock Purchase and Matching Plan.

For federal income tax purposes, a participant generally will not recognize taxable income on the grant of the right to purchase and acquire shares under the Stock Purchase and Matching Plan, nor will the Company be entitled to any deduction at that time. Upon the purchase of shares under the purchase component of the Stock Purchase and Matching Plan, a participant generally will not recognize taxable income and instead will recognize ordinary income in the amount equal to the fair market value of the Restricted Shares issued under the matching component when the risk of forfeiture on the Restricted Shares lapses. The Company will be entitled to a corresponding deduction when the risk of forfeiture on the Restricted Shares lapses. A participant’s basis in Purchased Shares, for purposes of determining the participant’s gain or loss on subsequent disposition of such shares of common stock, generally, will be equal to the purchase price paid for such shares. A participant’s basis in Restricted Shares, for purposes of determining the participant’s gain or loss on subsequent disposition of such shares of common stock, generally, will be the fair market value of the shares of common stock on the date the risk of forfeiture on such shares lapse.

Upon the subsequent sale of the shares acquired under the Stock Purchase and Matching Plan, the participant will recognize capital gain or loss (long-term or short-term, depending on how long the shares were held following the date of purchase for Purchased Shares and the lapse of the risk of forfeiture for Restricted Shares prior to disposing of them).

The above is a general summary under current law of the material federal income tax consequences to an employee who participates in the Stock Purchase and Matching Plan. This summary deals with the general federal income tax principles that apply and is provided only for general information. Some kinds of taxes, such as state, local and foreign income taxes and federal employment taxes, are not discussed. Tax laws are complex and subject to change and may vary depending on individual circumstances and from locality to locality. The summary above does not discuss all aspects of federal income taxation that may be relevant in light of a participant’s personal circumstances. Further, this summarized tax information is not tax advice and a participant in the Stock Purchase and Matching Plan should rely on the advice of his or her legal and tax advisors.
