 participate (See Question 12). Can I make optional cash payments through automatic payroll 
 deductions?                                                                                |

If you are an eligible employee
and have completed six (6) months of consecutive employment and you have already enrolled in the Plan (see Questions 7, 8 and 9),
you can enroll to make optional cash payments through automatic payroll deductions by completing an Employee Payroll Deduction Authorization
Form and submitting it to the Company (if you have not previously enrolled in the Plan, you may do so at the same time you enroll
to make optional payroll deductions). The Company (and the Plan Agent) must receive your forms sufficiently in advance of your next paycheck
to allow for processing. The minimum payroll deduction is $10, and the maximum deduction is $200 per pay period. Payroll deductions will
be counted against the limitation on optional cash payments discussed in Question 13. Once authorized, payroll deductions will continue
until changed or terminated by you. Note: No interest will be paid on payroll deductions held by the Company or the Plan Agent pending investment.
