You acknowledge that due to your executive position in the Company and your knowledge of the Company's confidential and proprietary information, your employment
or affiliation with certain entities would be detrimental to the Company. You agree that, without the prior written consent of the Cablevision, you will not represent, become employed by, consult to,
advise in any manner or have any material interest in any business directly or indirectly in any Competitive Entity (as defined below). A "Competitive

(ii) any company that competes with any of the Company's cable television, telephone or on-line data businesses in the New York greater metropolitan area or that competes with any

National Cable Television Association and any state cable television association. Ownership of not more than 1% of the outstanding stock of any publicly traded company shall not be a violation of this
paragraph. This agreement not to compete will become effective on the date of the Agreement and will expire upon the first anniversary of the date of your termination of employment with the Company.

Additional Understandings

You agree, for yourself and others acting on your behalf, that you (and they) have not disparaged and will not disparage, make negative statements about or act
in any manner which is intended to or does damage to the good will of, or the business or personal reputations of the Company or any of its incumbent or former officers, directors, agents,
consultants, employees, successors and assigns.

This
agreement in no way restricts or prevents you from providing truthful testimony concerning the Company to judicial, administrative, regulatory or other governmental authorities.

In
addition, you agree that the Company is the owner of all rights, title and interest in and to all documents, tapes, videos, designs, plans, formulas, models, processes, computer programs,
inventions (whether patentable or not), schematics, music, lyrics and other technical, business, financial, advertising, sales, marketing, customer or product development plans, forecasts, strategies,

"Materials"). The Company will have the sole and exclusive authority to use the Materials in any manner that it deems appropriate, in perpetuity,
without additional payment to you.

Further Cooperation

Subject to the terms of any consulting agreement entered into pursuant to this Agreement, following the date of termination of your employment with the Company
(the "Expiration Date"), you will no longer provide any regular services to the Company or represent yourself as a Company agent. If, however, the
Company so requests, you agree to cooperate fully with the Company in connection with any matter with which you were involved prior to the Expiration Date, or in any litigation or administrative
proceedings or appeals (including any preparation therefore) where the Company believes that your personal knowledge, attendance and participation could be beneficial to the Company. This cooperation
includes,

representatives, agents or vendors. The Company will pay you for your services rendered under this provision at the rate of $8,400 per day for each day or part thereof, within 30 days of
approved invoice therefore.

Unless
the Company determines in good faith that you have committed any malfeasance during your employment by the Company, the Company agrees that its corporate officers and directors, employees in
its public relations department or third party public relations representatives retained by the Company will not disparage you or make negative statements in the press or other media which are
damaging to your business or personal reputation. In the event that the Company so
disparages you or makes such negative statements, then notwithstanding the "Additional Understandings" provision to the contrary, you may make a proportional response thereto.

The
Company will provide you with reasonable notice in connection with any cooperation it requires in accordance with this section and will take reasonable steps to schedule your cooperation in any
such matters so as not to materially interfere with your other professional and personal commitments. The Company will reimburse you for any reasonable out-of-pocket expenses
you reasonably incur in connection with the cooperation you provide hereunder as soon as practicable after you present appropriate documentation evidencing such expenses. You agree to provide the
Company with an estimate of such expense before you incur the same.

Non-Hire or Solicit

You agree not to hire, seek to hire, or cause any person or entity to hire or seek to hire (without the prior written consent of the Company), directly or
indirectly (whether for your own interest or any other person or entity's interest) any current employee of the Company, or any of its subsidiaries or affiliates, for the term of the Agreement and
until one year after the termination of your employment. This restriction does not apply to any employee who was discharged by the Company. In addition, this restriction will not prevent you from
providing references.

Annex C

DISPUTE RESOLUTION(This Annex constitutes part of the Agreement)

Any controversy or claim between you and the Company relating to an Employment Matter will be finally settled by arbitration in the County of New York
administered by the American Arbitration Association (the "AAA") under its Commercial Arbitration Rules then in effect. However, the AAA's Commercial
Arbitration Rules will be modified in the following ways: (i) the decision must not be a compromise but must be the adoption of the submission by one of the parties, (ii) each arbitrator
will agree to treat as confidential, all evidence and other information presented to the arbitrator, (iii) there will be no authority to award punitive damages (and you and the Company agree
not to request any such award), (iv) there will be no authority to amend or modify the terms of this Agreement (and you and the Company agree not to request any such amendment or modification),
(v) a decision must be rendered within ten business days of the parties' closing statements or submission of post-hearing briefs, and (vi) the arbitration shall be conducted
before a panel of three arbitrators, one selected by you within 10 days of the commencement of the arbitration, one selected by the Company within the same period and the third selected jointly
by the arbitrators selected by you and the Company or, if they are unable to so agree upon an arbitrator who accepts the appointment within 30 days of the commencement of the arbitration, an
arbitrator shall be appointed by the AAA; provided, however, that such arbitrator shall be a partner or former partner at a nationally recognized law firm.

You
or the Company may bring an action or special proceeding in a state or federal court of competent jurisdiction sitting in the County of New York to enforce any arbitration award under the
immediately preceding paragraph. Also, the Company may bring such an action or proceeding, in addition to its rights under, and notwithstanding, the immediately preceding paragraph and whether or not
an arbitration proceeding has been or is ever initiated, to temporarily, preliminarily or permanently enforce any of the covenants inAnnex B. You agree
that (i) violating any of the covenants inAnnex Bwould cause damage to the Company that cannot be measured or repaired, (ii) the Company
therefore is entitled to an injunction, restraining order or other equitable relief restraining any actual or threatened violation of the covenants inAnnex
B, (iii) no bond bill needs to be posted for the Company to receive such an injunction, order or other relief and (iv) no proof will be required that monetary
damages for violations of the covenants inAnnex Bwould be difficult to calculate and that remedies at law would be inadequate.

You and the Company irrevocably submit to the exclusive jurisdiction of any state or federal court located in the County of New York over any Employment Matter that is not
otherwise arbitrated or resolved according to the next preceding paragraph.This includes any action or proceeding to compel arbitration or to enforce an arbitration award.
Both you and the Company (i) acknowledge that the forum stated in this paragraph has a reasonable relation to this Agreement and to the relationship between you and the Company and that the
submission to the forum will apply even if the forum chooses to apply non-forum law, (ii) waive, to the extent permitted by law, any objection to personal jurisdiction or to the
laying of venue of any action or proceeding covered by this paragraph in the forum stated in this

C-1

---

paragraph,
(iii) agree not to commence any such action or proceeding in any forum other than the forum stated in this paragraph and (iv) agree that, to the extent permitted by law, a
final and non-appealable judgment in any such action or proceeding in any such court will be conclusive and binding on you and the Company. However, nothing in this Agreement precludes you
or the Company from bringing any action or proceeding in any court for the purpose of enforcing the provisions of the next preceding paragraph and this paragraph.
