Security and Issuer

This Amendment No. 4 (this “Amendment No. 4”) amends and supplements the Schedule 13D filed by The Alpine Group, Inc. (“Alpine”) on February 26, 2007 (the “Original Schedule 13D”), as previously amended by Amendment No. 1 to the Original Schedule 13D, filed on March 20, 2008, Amendment No. 2 to the Original Schedule 13D, filed on July 18, 2008 and Amendment No. 3 to the Original Schedule 13D, filed on September 5, 2008 (as so amended, the “Schedule 13D”). Certain capitalized terms used but not defined in this Amendment No. 4 have the meanings given to them in the Schedule 13D.

Item 3.

Source and Amount of Funds or Other Consideration

The following paragraphs shall be added to the final paragraph of Item 3 of the Schedule 13D:

Pursuant to the terms of the Plan and the Alpine Stock Option Agreement, on March 29, 2009, Alpine Stock Options equal to approximately 1,296,207 shares of Common Stock vested and became exercisable by Alpine.

On April 28, 2009, the Company consummated its previously announced exchange offer in reliance upon the exemption from registration provided by Section 3(a)(9) of the Securities Act of 1933, as amended. Under the terms of the exchange offer, the Company offered holders of its 10-1/2% Senior Notes due 2009 (the “Senior Notes”) the opportunity to exchange any and all of their Senior Notes for the Company’s newly issued 15% Senior Secured Notes due 2012 (the “New Notes”) and a cash exchange fee equal to 3.0% of the principal amount of Senior Notes tendered. Approximately 83.5% of the Senior Notes were exchanged for New Notes, and holders of Senior Notes that did not participate in the exchange offer received a cash payment equal to the sum of the accrued and unpaid interest and the principal amount due at maturity. After the consummation of the exchange offer, all of the Senior Notes were cancelled by the trustee and the indenture governing the Senior Notes was discharged. Accordingly, the provisions of the Voting Agreement detailed in the description thereof in Item 5(c) below which restrict Alpine’s total voting power with respect to all voting securities of the Company (together with certain other persons) to less than 49% are no longer applicable.

Item 5 of the the Schedule 13D is hereby amended and supplemented as follows:

Item 5.

Interest in Securities of the Issuer

The following shall replace (a) and (b) of Item 5 of the Schedule 13D:

(a) Aggregate Number and Percentage of Class Beneficially Owned: 63,808,209; 62.6% (See Item 5(c) below).

(b) Number of shares as to which such person has:

(i) Sole power to vote or to direct the vote: 0 (See Item 5(c) below).

(ii) Shared power to vote or to direct the vote: 63,808,209 (See Item 5(c) below).

(iii) Sole power to dispose or to direct the disposition of: 25,895,982 (See Item 5(c) below).

(iv) Shared power to dispose or to direct the disposition of: 0 (See Item 5(c) below).

The final paragraph of Item 5(c) of the Schedule 13D shall be deleted and replaced with the following paragraph:

Pursuant to a voting agreement among the Company and the Purchasers entered into at the Closing and amended at the time of the Series B Closing (the “Voting Agreement”) and pursuant to the terms of the Series A Preferred Stock, for so long as any of the Company's 10-1/2% Senior Notes due 2009 are outstanding, neither Alpine or Plainfield (together with any other person with whom that Purchaser would be considered a “person” (as that term is used in Sections 13(d) and 14(d) of the Exchange Act) with respect to the Series A Preferred Stock, the Series B Preferred Stock or the Common Stock, which may include Alkest) were permitted to vote Common Stock (however acquired), Series A Preferred Stock and Series B Preferred Stock in excess of 49% of the total voting power of all voting securities of the Company. However, as of the consummation of the exchange offer, the 49% limitation in the Voting Agreement is no longer applicable. Accordingly, given Plainfield’s holdings of 38,000 shares of Series A Preferred Stock and 1,548,589 shares of Common Stock and Alkest’s holdings of 2,000 shares of Series A Preferred Stock, the aggregate voting power of all shares of Series A Preferred Stock, Series B Preferred Stock, Common Stock and Alpine Stock Options currently beneficially owned by Alpine, Plainfield and Alkest is 63,808,209.
