This Amendment No. 10 to Schedule 13D amends or amends and restates, where indicated, the statement on Schedule 13D relating to the Common Stock of the Issuer filed by Maurice Marciano with the Securities and Exchange Commission on June 10, 2003, as amended by filings on June 21, 2004, July 8, 2004, October 21, 2004, May 15, 2006, February 20, 2007, July 23, 2007, October 18, 2007, April 23, 2008 and January 29, 2010.  Capitalized terms used in this Amendment No. 10 but not otherwise defined herein have the meanings given to them in the initial Schedule 13D.
 
This Amendment No. 10 is being made primarily to reflect the sales of shares for portfolio diversification and estate planning purposes.  Except as otherwise set forth herein, this Amendment No. 10 does not modify any of the information previously reported by Maurice Marciano in the Schedule 13D as amended to date.
 
Item 5. | Interest in Securities of the Issuer
 
(a) As of April 27, 2010, Mr. Marciano may be deemed to beneficially own 17,886,023 shares of Common Stock which represents 19.2% of the 93,042,288 shares of the Common Stock that would be outstanding if he were to exercise all options exercisable within 60 days.  Of these shares, the following shares are also includable in Section 13 reports by his brother, Paul Marciano: 2,329,942 shares as a result of shared investment power over such shares, 1,650,000 shares as a result of Paul Marciano’s shared voting power over such shares and 1,004,733 shares as a result of Paul Marciano’s sole investment power over such shares.  If the 2,169,705 of these shares in which Maurice Marciano holds no pecuniary interest are subtracted to eliminate double counting, Maurice Marciano would be deemed to beneficially own 16.9% of such outstanding shares.  As of March 22, 2010, there were 92,897,088 shares of Common Stock outstanding, as reported in the Annual Report on Form 10-K of the Issuer for the year ended January 30, 2010.
 
(b) The 17,886,023 shares that may be deemed to be beneficially owned by Maurice Marciano, pursuant to Rule 13d-3 under the Securities Exchange Act of 1934, are held as follows:

* Maurice Marciano has a pecuniary interest in only 1,164,970 of these shares.  Because investment power over all shares held by this entity is shared with his brother, Paul Marciano, all of these shares also may be deemed to be beneficially owned by Paul Marciano.
 
** Maurice Marciano has no pecuniary interest in these shares. Because investment power over all shares held by this entity is held by his brother, Paul Marciano, all of these shares also may be deemed to be beneficially owned by Paul Marciano.
