THE HOLDER OF THIS NOTE OR ANY INTEREST HEREIN REPRESENTS AND WARRANTS THAT EITHER (A) IT IS NOT, AND IS NOT INVESTING ON BEHALF OF, (I) A “BENEFIT PLAN INVESTOR” WITHIN THE MEANING OF THE U.S.

EMPLOYEE RETIREMENT INCOME SECURITY ACT OF 1974, AS AMENDED (“ERISA”) AND THE REGULATIONS PROMULGATED THEREUNDER BY THE U.S. DEPARTMENT OF LABOR, AS MODIFIED BY SECTION 3(42) OF ERISA), OR (II) A PLAN, INDIVIDUAL RETIREMENT ACCOUNT OR OTHER ARRANGEMENT WHICH IS SUBJECT TO THE PROVISIONS OF ANY U.S. OR NON-U.S. FEDERAL, STATE, LOCAL OR OTHER LAWS OR REGULATIONS THAT ARE SIMILAR TO THE FIDUCIARY RESPONSIBILITY OR PROHIBITED TRANSACTION PROVISIONS OF TITLE I OF ERISA OR SECTION 4975 OF THE U.S. INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE “CODE”) (COLLECTIVELY, “OTHER PLAN LAWS”) OR OF AN ENTITY WHOSE ASSETS ARE DEEMED TO CONSTITUTE THE ASSETS OF ANY OF THE FOREGOING DESCRIBED IN THIS CLAUSE (II) PURSUANT TO APPLICABLE LAW, OR (B) IT’S PURCHASE AND HOLDING OF THIS NOTE OR ANY INTEREST HEREIN WILL NOT RESULT IN A NON-EXEMPT PROHIBITED TRANSACTION UNDER SECTION 406 OF ERISA OR SECTION 4975 OF THE CODE OR A SIMILAR VIOLATION OF ANY APPLICABLE OTHER PLAN LAWS.

THE NOTES ARE NOT INSURED OR GUARANTEED BY ANY GOVERNMENTAL AGENCY OR INSTRUMENTALITY OF THE UNITED STATES OR BY ANY OTHER PERSON OTHER THAN BY THE ASSET ENTITIES AND THE GUARANTOR.

THE OUTSTANDING NOTE PRINCIPAL BALANCE HEREOF AT ANY TIME MAY BE LESS THAN THE AMOUNT SHOWN ABOVE.

This certifies that [___] is the registered owner of the percentage interest evidenced by this Note (obtained by dividing the principal amount of this Note (its “Note Principal Balance”) as of the Closing Date by the Initial Class Principal Balance of the Class of Notes to which this Note belongs specified above) in the Class A-1-V Notes of this Series (the “Percentage Interest”). The Notes were issued pursuant to the Base Indenture, dated as of March 3, 2026 (together with all modifications, supplements, amendments and restatements thereof, the “Indenture”), as supplemented by a Series Supplement relating to this Series, among the Issuer, the Asset Entities party thereto and Wilmington Trust, National Association, as indenture trustee and not in its individual capacity (in such capacity, together with its successors, the “Indenture Trustee”) and are subject to the Class A-1-V Note Purchase Agreement, dated as of March 3, 2026 (together with all modifications, supplements, amendments and restatements thereof, the “Class A-1-V Note Purchase Agreement”) among Issuer, the Asset Entities party thereto, Cablevision Lightpath LLC, certain conduit investors from time to time party thereto, certain financial institutions from time to time party thereto, certain funding agents from time to time party thereto and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Asset Funding, Inc., as the Series 2026-1 Class A-1-V Administrative Agent, a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein have the respective meanings assigned thereto in the Indenture. This Note is issued under and is subject to the terms, provisions and conditions of the Indenture and the Class A-1-V Note Purchase Agreement, to which Indenture and Class A-1-V Note Purchase Agreement the Holder of this Note by virtue of its acceptance hereof assents and by which such Holder is bound.

A-2

Pursuant to the terms of the Indenture, beginning on the initial Payment Date specified above, payments will be made on the 25th day of each calendar month or, if any such 25th day is not a Business Day, on the next succeeding Business Day (each a “Payment Date”) to the Person in whose name this Note is registered at the close of business on the last Business Day of the Collection Period with respect to such Payment Date occurs (the “Record Date”), in an amount equal to the product of the Percentage Interest evidenced by this Note and the amount required to be paid to all the Holders of the Class of Notes of this Series to which this Note belongs on the applicable Payment Date pursuant to the Indenture. All payments made under the Indenture on this Note will be made by the Indenture Trustee by wire transfer of immediately available funds to the account of the Person entitled thereto at a bank or other entity having appropriate facilities therefor, if this Noteholder shall have provided the Indenture Trustee with wiring instructions no later than five (5) Business Days prior to the related Record Date (which wiring instructions may be in the form of a standing order applicable to all subsequent payments), or otherwise by check mailed to the address of this Noteholder as it appears in the Note Register. Notwithstanding the foregoing, the final payment on this Note will be made in like manner, but only upon presentation and surrender of this Note at the offices of the Note Registrar or such other location specified in the notice to the Holder hereof of such final payment.

This Note shall accrue interest during each Interest Accrual Period on the Note Principal Balance of this Note immediately prior to the related Payment Date at a rate per actual annum equal to the Note Rate specified above. Interest on this Note shall be calculated on an Actual/360 Basis.

As provided in the Indenture, withdrawals from the Collection Account may be made from time to time for purposes other than, and, in certain cases, prior to, payments to Noteholders, such purposes including the reimbursement of advances made, or certain expenses incurred, with respect to the Notes and the payment of interest on such advances and expenses.

Any payment to the Holder of this Note in reduction of the Note Principal Balance hereof is binding on such Holder and all future Holders of this Note and any Note issued upon the transfer hereof or in exchange therefor or in lieu hereof whether or not notation of such payment is made upon this Note.

This Note is issuable in fully-registered form only without coupons. As provided in the Indenture and subject to certain limitations therein set forth, this Note is exchangeable for new Notes of the same Class of the same Series in authorized denominations evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

No transfer, sale, pledge or other disposition of any Note or interest therein shall be made unless that transfer, sale, pledge or other disposition is exempt from the registration or qualification requirements of the Securities Act and any applicable state securities laws, or is otherwise made in accordance with the Securities Act and such state securities laws.

A-3

If a transfer of any Note is to be made without registration under the Securities Act (other than in connection with the initial issuance of the Notes), then such transfer shall not be registered by the Note Registrar unless the Note Registrar receives (and, upon receipt, may conclusively rely upon) either: (i) a certificate from the Noteholder desiring to effect such transfer substantially in the form attached as Exhibit B-4 to the Indenture, in the case of a transfer to a Qualified Institutional Buyer, or Exhibit B-5 to the Indenture, in the case of a transfer to an Institutional Accredited Investor, and a certificate from the prospective Transferee substantially in the form attached as Exhibit B-2 to the Indenture, in the case of a transfer to a Qualified Institutional Buyer, or Exhibit B-3 to the Indenture, in the case of a transfer to an Institutional Accredited Investor; or (ii) an Opinion of Counsel to the effect that such transfer may be made without registration under the Securities Act (which Opinion of Counsel shall not be an expense of the Issuer, the Servicer, the Indenture Trustee, the Manager or the Note Registrar in their respective capacities as such), together with the written certification(s) as to the facts surrounding such transfer from the Noteholder desiring to effect such transfer or such Noteholder’s prospective Transferee on which such Opinion of Counsel is based.

This Definitive Note may be exchanged for an interest in, or transferred to a transferee taking an interest in the form of an Uncertificated Note subject to the restrictions set forth in the Indenture and any Series Supplement.

None of the Issuer, the Indenture Trustee or the Note Registrar shall be obligated to register or qualify any Class of Notes under the Securities Act or any other securities law or to take any action not otherwise required under the Indenture to permit the transfer of any Note or interest therein without registration or qualification. Any Noteholder or Note Owner desiring to effect a transfer, sale, pledge or other disposition of any Note or interest therein shall, and does hereby agree to, indemnify the Parent, the Guarantor, the Obligors, the Indenture Trustee, the Manager, the Servicer and the Note Registrar against any liability that may result if such transfer, sale, pledge or other disposition is not exempt from the registration or qualification requirements of the Securities Act and any applicable state securities laws or is not made in accordance with such federal and state laws.

No transfer of any Note or any interest therein shall be made to any Benefit Plan Investor or Plan Investor or to any Person who is directly or indirectly acquiring such Note on behalf of, as fiduciary of, as trustee of, or with the assets of, a Benefit Plan Investor or Plan Investor, except in each such case, in accordance with the provisions of Section 2.02(c) of the Indenture. Any attempted or purported transfer of a Note in violation of Section 2.02(c) of the Indenture will be null and void and vest no rights in any purported Transferee.

The Note Registrar shall not register the transfer of a Note that constitutes a Definitive Note or the transfer of an interest in an Uncertificated Note that following such purported transfer will constitute a Definitive Note, unless the Note Registrar has received from the prospective Transferee a certification that either:

(i) such prospective Transferee is not a Benefit Plan Investor or Plan Investor or any Person who is directly or indirectly acquiring or holding such Note or any interest therein on behalf of, as fiduciary of, as trustee of, or with assets of, any Benefit Plan Investor or Plan Investor; or

A-4

(ii) such purchase and holding of such Note or any interest therein will not result in a non-exempt prohibited transaction under Title I of ERISA or Section 4975 of the Code or a violation of any applicable Other Plan Law.

It is hereby acknowledged that either of the forms of certification attached to the Indenture as Exhibits B-2 and B-3 is acceptable for purposes of clauses (i) and (ii) of the preceding sentence.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registerable in the Note Register upon surrender of this Note for registration of transfer at the offices of the Note Registrar, duly endorsed by, or accompanied by a written instrument of transfer in the form satisfactory to the Note Registrar duly executed by the Holder hereof or his attorney duly authorized in writing, with such signature guaranteed by an “eligible guarantor institution” meeting the requirements of the Note Registrar, which requirements include membership or participation in the Security Transfer Agent Medallion Program (“STAMP”) or such other “signature guarantee program” as may be determined by the Registrar in addition to, or in substitution for, STAMP, all in accordance with the Securities Exchange Act of 1934, as amended, and accompanied by such other documents as the Indenture Trustee and the Note Registrar may require, and thereupon one or more new Notes of the same Class of the same Series in authorized denominations evidencing a like aggregate Percentage Interest will be issued to the designated transferee or transferees.

No service charge will be imposed for any transfer or exchange (or de-registration) of this Note, but the Indenture Trustee or the Note Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any transfer or exchange (or de-registration) of this Note.

The Issuer, the Servicer, the Indenture Trustee, the Note Registrar and any agent of the Issuer, the Servicer, the Indenture Trustee or the Note Registrar may treat the Person in whose name this Note is registered as the owner hereof for all purposes, and none of the Issuer, the Servicer, the Indenture Trustee, the Note Registrar or any such agent shall be affected by notice to the contrary.

Each Holder of this Note, by accepting this Note, and each Note Owner of an interest in this Note, by accepting an ownership interest in this Note, hereby covenants and agrees that neither it nor the Indenture Trustee on behalf of it will at any time institute against the Issuer and/or the Asset Entities or the Guarantor, or join in any institution against the Issuer and/or the Asset Entities or the Guarantor of, any bankruptcy, reorganization, insolvency or similar proceedings, or other proceedings under any federal, state or foreign bankruptcy or similar law in connection with any obligations relating to the Notes, the Indenture or any of the other Transaction Documents.

Notwithstanding anything to the contrary in the Indenture or any Series Supplement, all obligations of the Issuer under this Note shall be deemed to be extinguished in the event that, at any time, the Issuer, the Guarantor and the Asset Entities have no assets (which shall include claims that may be asserted by the Issuer, the Guarantor and the Asset Entities with respect to contractual obligations of third parties to the Issuer, the Guarantor and the Asset Entities but which shall not include the proceeds of the issue of their Equity Interests). No further claims may be brought against any of the Obligors’ directors or officers or against their shareholders or members, as the case may be, for any such obligations, except in the case of fraud or actions taken in bad faith by such Persons.

A-5

Subject to certain terms and conditions set forth in the Indenture, the Obligations created by the Indenture shall terminate upon payment (or provision for payment) to the Noteholders of all amounts held by or on behalf of the Indenture Trustee and required under the Indenture to be so paid on the Payment Date following the final payment or other liquidation (or any advance with respect thereto) of the Notes.

The Base Indenture permits certain amendments to be made thereto without the consent of the Servicer, the Controlling Class Representative or any Noteholders, provided that certain conditions precedent are satisfied. The Indenture also permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the rights of the Noteholders under the Base Indenture, any Series Supplement or the Notes, or waiver of compliance by the Issuer with any provision of the Indenture, any Series Supplement or the Notes, at any time by the Issuer with the consent of (a) the Servicer (who shall have no liability for consenting to or rejecting such Indenture Supplement, in the absence of its own gross negligence, bad faith, willful misconduct or fraudulent behavior) or (b) Noteholders representing more than 50% of the Class Principal Balance of each Class of Notes adversely affected thereby. Any such consent or waiver of this Note (or any one or more predecessor Notes) shall be conclusive and binding upon such Noteholder and upon all future Noteholders of this Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent or waiver is made upon this Note.

Unless the certificate of authentication hereon has been executed by the Note Registrar, by manual, electronic or facsimile signature, this Note shall not be entitled to any benefit under the Indenture or be valid for any purpose.

The registered Holder hereof, by its acceptance hereof, agrees that it will not have at any time recourse for payments hereunder against the Indenture Trustee, the Servicer or any Agents and Affiliates thereof.

THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF LAW PRINCIPLES (OTHER THAN SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW) INCLUDING ANY CLAIM OR CONTROVERSY ARISING OUT OF OR RELATING TO THIS NOTE.
