Finance LLC, a limited liability company organized under the laws of the State of Delaware) (the “Issuer”), each of the parties identified as a Guarantor on the signature pages hereto (each, a “Guarantor” and
collectively, the “Guarantors”) and Wilmington Trust, National Association, as trustee (the “Trustee”) and as collateral agent (in such capacity, the “Collateral Agent”). 

W I T N E S S E T H 
 WHEREAS,
CommScope Finance LLC, the Trustee and the Collateral Agent are parties to an indenture dated as of February 19, 2019 (the “Indenture”), providing for the issuance of the Issuer’s 5.50% Senior Secured Notes due 2024 and
6.00% Senior Secured Notes due 2026 (collectively, the “Notes”); 
 WHEREAS, the Issuer and each Guarantor that is a
signatory hereto is executing this Supplemental Indenture pursuant to which (i) the Issuer shall become a party to the Indenture and assume all of the rights and be subject to all of the obligations and agreements of the “Issuer”
under the Indenture and (ii) each such Guarantor shall become a party to the Indenture and assume all of the rights and be subject to all of the obligations and agreements of a “Guarantor” under the Indenture; 

WHEREAS, Section 3.11—Future Guarantors of the Indenture provides that under certain circumstances the Guarantors shall execute and
deliver to the Trustee a supplemental indenture pursuant to which the Guarantors shall unconditionally guarantee all of the Issuer’s obligations under the Notes and the Indenture on the terms and conditions set forth herein; and 

WHEREAS, pursuant to Section 9.1—Amendments Without Consent of Holders of the Indenture, the Trustee is authorized to execute and
deliver this Supplemental Indenture. 
 NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the
receipt of which is hereby acknowledged, the Issuer, the Guarantors and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders as follows: 

1. Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture. 

2. Agreement to be Bound. Without limiting the assumption by operation of law upon the Escrow Merger, the Issuer hereby becomes party to
the Indenture as the “Issuer” for all purposes thereof and as such will have all of the rights and be subject to all of the obligations and agreements of the “Issuer” under the Indenture. 

3. Agreements to Become Guarantors. Each of the Guarantors hereby unconditionally guarantees the Issuer’s obligations for the due
and punctual payment of the principal of, premium, if any, and interest on all the Notes and the performance and observance of each other obligation and covenant set forth in the Indenture to be performed or observed on the part of the Issuer, on
the terms and subject to the conditions set forth in Article X—Guarantees of the Indenture, and agrees to be bound by all other provisions of the Indenture and the Notes applicable to a Guarantor therein. 












 4. Ratification of Indenture; Supplemental Indenture Part of Indenture. Except as
expressly amended hereby, the Indenture is in all respects ratified and confirmed and all the terms, conditions and provisions thereof shall remain in full force and effect. This Supplemental Indenture shall form a part of the Indenture for all
purposes, and every Holder heretofore or hereafter authenticated and delivered shall be bound hereby. 
 5. No Recourse Against
Others. No manager, managing director, director, officer, employee, incorporator or holder of any Equity Interests in the Issuer, any Subsidiary or any direct or indirect parent of the Issuer, as such, shall have any liability for any
obligations of the Issuer or the Guarantors under the Notes, the Indenture, the Security Documents, the Intercreditor Agreements or any Guarantee or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each
Holder, by accepting a Note, waives and releases all such liability. This waiver and release are part of the consideration for the issuance of the Notes. This waiver may not be effective to waive liabilities under the federal securities laws and it
is the view of the SEC that such a waiver is against public policy. 
 6. Notices. For purposes of Section 12.1—Notices of
the Indenture, the address for notices to each of the Issuer and the Guarantors shall be: 
 CommScope, Inc.
