Federal Tax Considerations
The following summarizes certain United States federal income tax considerations for employees participating in the 2008 Purchase Plan and certain tax effects to SBA. This summary, however, does
not address every situation that may result in taxation. For example, it does not discuss foreign, state, or local taxes, or any of the tax implications arising from a participants death. This summary is not intended as a substitute for careful tax planning, and each employee is urged to consult with and rely on his or her own advisors with respect to the possible tax consequences (federal, state, local and foreign) of exercising his or her rights under the 2008 Purchase Plan. The 2008 Purchase Plan is not subject to the provisions of the Employee Retirement Income Security Act of 1974 nor the provisions of Section 401(a) of the Code.
For U.S. federal income tax purposes, an employee does not realize income at the time of entry into the 2008 Purchase Plan or purchase of a share. If no disposition of the shares is made within two years from the first day of an Option Period, or one year from the date the shares are purchased by the employee, upon subsequent disposition of the shares, the employees gross income for the taxable year in which the disposition occurs will include as ordinary income and not as capital gain an amount equal to the lesser of (i) the excess of the fair market value of the stock at the time of the disposition over the option price, or (ii) the excess of the fair market value of the share at the time of grant over the option price. No income tax deduction will be allowed SBA for shares purchased by the employee, provided such shares are held for the periods described above. If the shares are disposed of within the periods described above, the employee will recognize ordinary income for the taxable year of the disposition equal to the excess of the fair market value of the shares on the date of purchase over the price paid, and in these circumstances, SBA will be entitled to a deduction equal to the amount of ordinary income recognized by the employee.
