Such exercise shall be for the purchase, on or as soon as practicable after each Purchase Date, of the number of full and/or fractional Shares that the accumulated payroll deductions credited to the Participant's Account as of such Purchase Date will purchase at the applicable Exercise Price (but not in excess of the number of Shares for which an Option has been granted to the Participant pursuant to Section 4.1).

C. Issuance of Certificates. Until a Participant has satisfied the Holding Period for any Shares held under the Plan, the Shares must (unless a disqualifying disposition is made) remain in a Participant's Account.
