           (c)  [***] of net sales in excess of US $ 200 million per quarter.

     For the purpose of this Article, "Net Sales" shall mean the invoice price
     for NAND Flash Memory Products billed by SanDisk.

          (iii) Notwithstanding (ii) above, SanDisk's quarterly contribution for
     Common R&D pursuant to (i) and (ii) above shall not exceed the sum of (a)
     [***] of the total Common R&D annual expenditure of the Semiconductor
     Company of Toshiba, as notified to SanDisk by Toshiba at the beginning of
     each of Toshiba fiscal year ("Total R&D Budget") for the first [***] of the
     Total R&D Budget and (b) [***] of the portion of such Total R&D Budget in
     excess of [***]."

consistent with Section 5.1(ii) of the Agreement, provided that the percentages
used in such calculation shall not exceed (a) the percentages of the applicable

forth in Section 5.1(iii) of the Agreement, as amended herein.
