         This Amendment No. 10 to the Schedule 13D ("Amendment No. 10") is being
filed by David I. Saperstein (the "Reporting  Person") pursuant to Rule 13d-2 of
the General Rules and Regulations under the Securities  Exchange Act of 1934, as

Stock is  convertible  with no premium into one share of Issuer  Common Stock at

1933,  as  amended.  Goldman,  Sachs & Co.  ("Goldman")  sold these  shares (the
"Brokerage  Shares") in its capacity as a broker for the Reporting  Person.  The
Brokerage  Shares were sold by the Reporting  Person for an aggregate  amount of
$58,500,000, representing an amount equal to $18.75 per Brokerage Share.

         Also on October 19, 1999,  the Reporting  Person  entered into a letter
agreement  (the  "Letter  Agreement")  with the  Issuer,  pursuant  to which the
Reporting Person sold 1,066,660 shares of Issuer Common Stock to the Issuer (the
"Stock  Repurchase")  pursuant to the  Issuer's  stock  repurchase  program (the
"Stock Repurchase Program").  Such shares (the "Repurchase Shares") were sold by
the Reporting  Person pursuant to the Issuer's Stock  Repurchase  Program for an
aggregate amount of  $19,999,875.00,  representing an amount equal to $18.75 per
