Article 2
GUARANTEE

Section 201 Guarantee.

(a)            The New Guarantors hereby fully and unconditionally guarantee the Notes of each series and the obligations of the Company thereunder and under the Indenture, and guarantee to each Holder of a Note of such series authenticated and delivered by the Trustee, and to the Trustee on behalf of such Holder, that (i) the principal of (and premium, if any) and interest on the Notes of such series will be paid in full when due, whether at Stated Maturity, by acceleration or otherwise (including, without limitation, the amount that would become due but for the operation of any automatic stay provision of any federal bankruptcy law), together with interest on the overdue principal, if any, and interest on any overdue interest, to the extent lawful, and all other obligations of the Company to the Holders or the Trustee under the Indenture or the Notes of such series will be paid in full or performed, all in accordance with the terms of the Indenture and the Notes of such series; and (ii) in case of any extension of time of payment or renewal of any Notes of such series or of any such other obligations, the same will be paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise.

(b)            The New Guarantors hereby agree that, in the event of a default in payment of principal (or premium, if any) or interest on an applicable series of Notes, whether at Stated Maturity, by acceleration, purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, a Holder of such Notes of such series, subject to the terms and conditions set forth in the Indenture, directly against the New Guarantors to enforce the Guarantee without first proceeding against the Company or any other guarantor. The New Guarantors agree that if, after the occurrence and during the continuance of an Event of Default with respect to an applicable series of Notes, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Notes of such series, to collect interest on the Notes of such series, or to enforce or exercise any other right or remedy with respect to the Notes of such series, the New Guarantors will pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders. Any term or provision of this Supplemental Indenture to the contrary notwithstanding, the maximum aggregate amount of the Obligations guaranteed hereunder by each New Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Supplemental Indenture, as it relates to such New Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

(c)            With respect to an applicable series of Notes, unless and until the Termination Date (as defined herein) has occurred, or the New Guarantors shall be released in accordance with Section 204 of this Supplemental Indenture, to the fullest extent permitted by applicable law, the New Guarantors shall remain obligated hereunder and the Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Company for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Company’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes of such series are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes of such series, whether as a “voidable preference”, “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Notes of such series shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

(d)            To the fullest extent permitted by applicable law, the New Guarantors waive diligence, presentment, protest and notice of protest, demand for payment or performance, notice of default or nonpayment, notice of acceptance and any other notice in respect of the Company’s obligations under any series of Notes and under the Indenture, and any defense arising by reason of any disability or other defense of the Company or the New Guarantors with respect to such obligations (other than the defense that the Termination Date has occurred or the New Guarantors have been released in accordance with Section 204 of this Supplemental Indenture). The New Guarantors understand and agree that this Agreement shall be construed as a continuing, absolute and unconditional guarantee of payment and performance and not merely of collectability, and its Guarantee of a particular series of Notes and the obligations of the Company under the Indenture hereunder shall not be affected by, and shall remain in full force and effect without regard to, and hereby waives all rights, claims or defenses that it might otherwise have (now or in the future) with respect to each of the following (whether or not the New Guarantors have knowledge thereof): (i) the validity, regularity or enforceability of the Notes of such series or the Indenture or the absence of any action to enforce the same, (ii) the recovery of any judgment against the Company or any action to enforce the same, (iii) any renewal, extension or acceleration of, or any increase in the amount of the Company’s obligations under such series of Notes and under the Indenture (whether or not any increase is committed, contemplated or provided for by the Indenture or the Notes of such series on the date hereof), (iv) any failure, omission or delay in enforcement (by agreement or otherwise), or the stay or enjoining (by court order, operation of law or otherwise) of the exercise of enforcement, of any claim or demand or any right, power or remedy (whether arising under the Indenture or the Notes of such series, at law, in equity or otherwise) with respect to the Company’s obligations under such series of Notes and under the Indenture or (v) any other circumstance whatsoever (with or without notice to or knowledge of the New Guarantors) which constitutes, or might be construed to constitute, an equitable or legal discharge of the New Guarantors under the Guarantee contained in this Article 2, in bankruptcy or in any other instance (in each case, other than the occurrence of the Termination Date or the release of the New Guarantors in accordance with Section 204 of this Supplemental Indenture).

(e)            The New Guarantors further agree that, as between the New Guarantors, on the one hand, and the Holders and the Trustee, on the other hand (i) subject to the terms and provisions of this Supplemental Indenture, the maturity of the obligations under an applicable series of Notes guaranteed hereby may be accelerated as provided in Article VI of the Indenture for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (ii) in the event of any acceleration of such obligations as provided in Article VI of the Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by the New Guarantors for the purpose of this Guarantee.

(f)             Subject to Section 204 of this Supplemental Indenture, the Guarantee of a series of Notes contained in this Article 2 shall remain in full force and effect until all the obligations of the Company under such series of Notes and under the Indenture shall have been satisfied by payment in full (such date, the “Termination Date”).

(g)            The Guarantee by the New Guarantors of a series of Notes shall be independent of and shall not be affected by the Guarantee by the New Guarantor of any other series of Notes.

(h)            For the avoidance of doubt, none of the New Guarantors are Guarantors under the Indenture. The guarantee of the New Guarantors is granted solely pursuant to and in accordance with the terms set forth in this Article 2.

Section 202 Subrogation. The New Guarantors shall be subrogated to all rights of Holders against the Company in respect of any amounts paid by the New Guarantors pursuant to its Guarantee; provided, however, that if an Event of Default has occurred and is continuing with respect to a series of Notes, the New Guarantors shall not be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Company under the Indenture or the applicable series of Notes shall have been paid in full.

Section 203 Reinstatement. Subject to Section 204 of this Supplemental Indenture, the Guarantee of a series of Notes contained in this Article 2 shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Company’s obligations with respect to such series of Notes or the Indenture is rescinded or must otherwise be restored or returned by the Trustee or any Holder upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the New Guarantors, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the New Guarantors or any substantial part of its property, or otherwise, all as though such payments had not been made.

Section 204 Release of Guarantee. Any New Guarantor shall, upon the occurrence of any of the following events, be automatically and unconditionally released and discharged from all obligations with respect to the Notes of an applicable series, the Indenture and the Guarantee of such series of Notes without any action required on the part of the Trustee or any Holder:

(a)            upon the occurrence of a Collateral Release Event;

(b)            at such time as such New Guarantor is either: (i) not an issuer or guarantor of any item of Indebtedness for Borrowed Money (whether by repayment or otherwise) and any other Equally and Ratably Secured Indebtedness and ceases (or substantially concurrently will cease) to be the guarantor of any Equally and Ratably Secured Indebtedness (or such New Guarantor’s obligations with respect to all Equally and Ratably Secured Indebtedness shall cease to exist substantially concurrently with such release of its Guarantee); or (ii) released or relieved as an issuer or guarantor of its obligations of an item of Indebtedness for Borrowed Money (whether by repayment or otherwise) and not an issuer or guarantor of any other Equally and Ratably Secured Indebtedness and ceases (or substantially concurrently will cease) to be the guarantor of any Equally and Ratably Secured Indebtedness (or such New Guarantor’s obligations with respect to all Equally and Ratably Secured Indebtedness shall cease to exist substantially concurrently with such release of its Guarantee);

(c)            upon the release by the Administrative Agent of the Guarantee (as defined in the Guarantee and Collateral Agreement (as defined in the Charter Credit Agreement)) of such New Guarantor;

(d)            upon the consummation of any transaction not prohibited by the Indenture that results in such New Guarantor ceasing to be a subsidiary of CCO;

(e)            upon any covenant defeasance or legal defeasance with respect to such series of Notes and the Indenture, or upon the discharge of the Company’s obligations with respect to such series of Notes and obligations under the Indenture in accordance with its terms;

(f)            upon (i) the consolidation or merger by the Company with or into any Person or (ii) the conveyance, transfer or lease of all or substantially all the assets of the Company, in a transaction that complies with the Indenture, such that the Company ceases to be a subsidiary of Cox Enterprise; or

(g)            upon (i) the consolidation or merger by Cox Enterprise with or into any Person or (ii) the conveyance, transfer or lease of all or substantially all the assets of Cox Enterprise, such that the Company ceases to be a subsidiary of Cox Enterprise.

The release of the New Guarantors’ Guarantee of an applicable series of Notes hereunder shall be independent of and shall not be affected by the release of the New Guarantors’ Guarantee of any other series of Notes. At the request and sole expense of the Company following any such termination, Collateral Agent shall execute and deliver to the Company such documents as the Company shall reasonably request to evidence such termination.

Section 205 Execution and Delivery. The New Guarantors hereby agree that the Guarantee of an applicable series of Notes will remain in full force and effect notwithstanding any failure to endorse on each Note of such series a notation of such Guarantee.

This Supplemental Indenture shall be governed by, and construed in accordance with, the laws of the State of New York.

Each of the Company, the Guarantors, the Trustee and the Collateral Agent (i) expressly and irrevocably consents to submit itself to the exclusive personal jurisdiction of the state courts in the Borough of Manhattan in the City of New York in the State of New York, and any federal court located in the Borough of Manhattan in the City of New York in the State of New York, together with any appellate court therefrom, with respect to all actions and proceedings arising out of the Indenture or the Guarantees and (ii) expressly and irrevocably waives (and agrees not to plead or claim) any objection to the laying of venue of any action or proceeding arising out of the Indenture or the Guarantees in such court or that any such action or proceeding brought in any such court has been brought in an inconvenient forum.
