Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

This Form 8-K is being filed in connection with a memorandum of understanding (a “memorandum of understanding”) regarding the settlement of certain litigation relating to the Agreement and Plan of Merger (the “Merger Agreement”), dated as of October 26, 2010, by and among CommScope, Inc., a Delaware corporation (the “Company”), Cedar I Holding Company, Inc., a Delaware corporation (“Parent”) that was formed by an affiliate of The Carlyle Group (“Carlyle”), and Cedar I Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), providing for the merger (the “Merger”) of Merger Sub with and into the Company.

As previously disclosed on pages 7 and 53 of the Definitive Proxy Statement on Schedule 14A filed with the Securities and Exchange Commission (the “SEC”) by the Company on December 6, 2010 (the “Definitive Proxy Statement”), four putative stockholder class action lawsuits were filed in connection with the Merger in the Court of Chancery of the State of Delaware against the Company, members of its board of directors, Parent, Merger Sub, and Carlyle asserting that the directors breached their fiduciary duties, and asserting that Parent, Merger Sub and Carlyle aided and abetted those alleged breaches of fiduciary duty. These four actions were consolidated before the Court of Chancery of the State of Delaware on November 23, 2010 under the caption In re CommScope Corp. Shareholders Litigation.

On December 17, 2010, we entered into a memorandum of understanding with the plaintiffs regarding the settlement of this consolidated putative stockholder class action.

The Company believes that no further disclosure is required to supplement the Definitive Proxy Statement under applicable laws; however, to avoid the risk that the putative stockholder class action may delay or otherwise adversely affect the consummation of the Merger and to minimize the expense of defending such action, the Company has agreed, pursuant to the terms of the proposed settlement, to make certain supplemental disclosures related to the proposed Merger, all of which are set forth below. Subject to completion of certain confirmatory discovery by counsel to the plaintiffs, the memorandum of understanding contemplates that the parties will enter into a stipulation of settlement. The stipulation of settlement will be subject to customary conditions, including court approval following notice to the Company’s stockholders. In the event that the parties enter into a stipulation of settlement, a hearing will be scheduled at which the Court of Chancery of the State of Delaware will consider the fairness, reasonableness, and adequacy of the settlement. If the settlement is finally approved by the court, it will resolve and release all claims in all actions that were or could have been brought challenging any aspect of the proposed Merger, the Merger Agreement, and any disclosure made in connection therewith (but excluding claims for appraisal under Section 262 of the Delaware General Corporation Law), pursuant to terms that will be disclosed to stockholders prior to final approval of the settlement. In addition, in connection with the settlement, the parties contemplate that plaintiffs’ counsel will file a petition in the Court of Chancery of the State of Delaware for an award of attorneys’ fees and expenses to be paid by the Company or its successor, which the defendants may oppose. The Company or its successor will pay or cause to be paid any attorneys’ fees and expenses awarded by the Court of Chancery of the State of Delaware. There can be no assurance that the parties will ultimately enter into a stipulation of settlement or that the Court of Chancery of the State of Delaware will approve the settlement even if the parties were to enter into such stipulation. In such event, the proposed settlement as contemplated by the memorandum of understanding may be terminated.

SUPPLEMENT TO DEFINITIVE PROXY STATEMENT

In connection with the settlement of all outstanding stockholder suits in the Chancery Court of the State of Delaware as described in this Form 8–K, the Company has agreed to make these supplemental disclosures to the Definitive Proxy Statement. This supplemental information should be read in conjunction with the Definitive Proxy Statement, which should be read in its entirety. Defined terms used but not defined herein have the meanings set forth in the Definitive Proxy Statement.

The following disclosure supplements the discussion on page 40 of the Definitive Proxy Statement concerning the Discounted Cash Flow Analysis.

Allen & Co. calculated terminal values for the Company by applying to the Company’s projected 2015 estimated adjusted EBITDA terminal value multiples of 7.0x to 8.0x, which range was selected taking into consideration, among other things, calendar years 2010 estimated adjusted EBITDA multiples derived for the selected companies referred to above under the caption “Selected Companies Analysis.” The cash flows and terminal values were then discounted to present value using discount rates ranging from 10.0% to 12.0%, which range was selected taking into consideration, among other things, a weighted average cost of capital calculation.

The following disclosure supplements the Miscellaneous discussion on page 40 of the Definitive Proxy Statement.
