ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

         On March 3, 2005 and March 4, 2005, Cablevision Systems Corporation
(the "Company") entered into amendments to its employment arrangements with
James L. Dolan, the Company's President and Chief Executive Officer, Hank J.
Ratner, the Company's Vice Chairman, Michael P. Huseby, the Company's Chief
Financial Officer, Thomas M. Rutledge, the Company's Chief Operating Officer,
and certain other officers of the Company (the "Affected Officers") to amend
those employment arrangements to comply with the new requirements imposed on
deferred compensation under Section 409A of the Internal Revenue Code of 1986,
as amended.

         The employment arrangements with the Affected Officers have been
amended to provide that if amounts owed to them upon termination of their
employment are subject to the new requirements, those payments and benefits will
be delayed by up to six months in order to prevent imposition of an additional
tax. These amounts would be paid to a trust for their benefit and then
distributed to them with earnings six months later. The amendments also clarify
that when they terminate employment, their equity-based awards will not be
extended beyond their regularly scheduled term (as if they had not been
terminated).
