You will be paid your base salary, sales commissions, allowances, and benefits for your services as an employee of QLogic, as in effect immediately prior to the Termination Date, for your services through the Termination Date. You will not accrue any additional compensation or entitlement to any employee benefits or be entitled to receive vacation or sick leave benefits after the Termination Date except as expressly provided herein. You will also not receive any bonus for services prior to the Termination Date or sales commissions in respect of sales after the Termination Date. Sales commissions otherwise payable to you in respect of sales prior to the Termination Date will be subject to adjustment for returns, credits, bad debts, and other like events after the Termination Date. 3. After the Termination Date, QLogic will provide you with gross separation payments equal to the regular amount of your prorated base salary for each payroll period, as in effect immediately prior to the Termination Date. Such separation payments shall be payable over the six (6) month period commencing October 11, 1995 and ending April 10, 1996 (the "Separation Payment Period") and shall be paid in equal installments on the customary QLogic salary payment days.
