This Statement on Schedule 13D/A relates to the common stock, par value $0.001 per share (“Common Stock”) of Cyalume Technologies Holdings, Inc., a Delaware corporation (formerly known as Vector Intersect Security Acquisition Corp.)

This Statement on Schedule 13D/A is being filed by: GMS Acquisition Partners Holdings, LLC, a Delaware limited liability company (“GMS”), Cova Small Cap Holdings, LLC, a Delaware limited liability company (“Cova”), Jason Epstein, an individual United States citizen (“Epstein”), Andrew Intrater, an individual United States citizen (“Intrater”), Renova US Holdings Ltd., a Bahamas corporation (“Renova”), Columbus Nova Investments IV Ltd., a Bahamas corporation (“Nova IV”), CN Special Opportunity Fund Ltd., a Bahamas corporation (“CN Fund”) and CN Credit Opportunities Fund 2007-1 Ltd., a Cayman Islands corporation (“CN 2007-1 Fund”).

The information set forth in response to each separate Item below shall be deemed to be a response to all Items where such information is relevant. The Schedule 13D originally filed on December 29, 2008 is hereby amended as follows:

On January 15, 2009, Cova participated in the sale, by certain of the parties to the Churchill Stock Purchase Agreement, of 625,000 shares of Common Stock to Churchill by selling, at a purchase price of $4.00 per share, 568,157 shares of Common Stock to Churchill, plus an additional 22,886 shares of Common Stock to account for a certain number of the remaining shares owed to Churchill pursuant to the Churchill Stock Purchase Agreement by members of GMS that did not participate in the January 15, 2009 sale as previously planned.

The information set forth in Item 4 above is hereby incorporated by reference into this Item 5. As of January 15, 2009, Cova directly beneficially owns an aggregate of 4,269,356 shares of Common Stock, or approximately 26.6% of the Common Stock then outstanding, and due to the relationships described below, each of the other Reporting Persons may be deemed to beneficially own such shares.

(1)

Cova directly beneficially owns 4,269,356 shares of Common Stock, constituting approximately 26.6% of the Common Stock outstanding as of January 15, 2009. Cova has sole voting power and sole investment power with respect to all the shares of Common Stock referred to in the previous sentence.

(2)

Intrater, as chief executive officer of Cova, may be deemed to beneficially own 4,269,356 shares of Common Stock, constituting approximately 26.6% of the Common Stock outstanding as of January 15, 2009. Intrater may be deemed to have shared voting power and shared investment power with respect to all the shares of Common Stock referred to in the previous sentence.

Renova may be deemed to have sole voting power and sole investment power with respect to all the shares of Common Stock referred to in the previous sentence.

(4)

Nova IV may be deemed to have sole voting power and sole investment power with respect to all the shares of Common Stock referred to in the previous sentence.

CN 2007-1 Fund may be deemed to have sole voting power and sole investment power with respect to all the shares of Common Stock referred to in the previous sentence.

As a result of their entry into the Investor Rights Agreement (as defined and described in Item 6 below), each of the parties thereto may be deemed to be members of a “group” under Section 13(d) of the Act. Accordingly, each of the parties to the Investor Rights Agreement may be deemed to beneficially own the shares of Common Stock held by each other party thereto, and certain other beneficial owners of Common Stock named in this Statement on Schedule 13D may be deemed to beneficially own the shares of Common Stock held by each of the parties to the Investor Rights Agreement by virtue of their relationships with such parties to the Investor Rights Agreement. As a result, the Reporting Persons believe, based on information available to them, that each Reporting Person may be deemed to beneficially own 7,908,433 shares of Common Stock in the aggregate, constituting approximately 49.3% of the Common Stock outstanding as of January 15, 2009.

Neither the filing of this Statement on Schedule 13D nor any of its contents shall be deemed to constitute an admission that any Reporting Person is the beneficial owner of any Common Stock referred to in this Statement on Schedule 13D for the purposes of Section 13(d) of the Act or for any other purpose, and, except as otherwise expressly stated herein, such beneficial ownership is expressly disclaimed.

(c) To the best knowledge of the Reporting Persons, except for the transactions described in this Statement on Schedule 13D, none of the Reporting Persons has effected any transactions in the securities of the Issuer during the past 60 days.

(d) Except as stated in this Item 5, to the knowledge of the Reporting Persons, only the Reporting Persons have the right to receive or the power to direct the receipt of dividends from, or proceeds from the sale of, the 4,269,356 shares of Common Stock held by Cova.

(“KH Pacific”) and Kline Hawkes Pacific Friends Fund, LLC (“KH Friends”). The Reporting Persons are aware that Mr. Frank Kline and Kline Hawkes Pacific Advisors, LLC may have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, those shares of Common Stock received by KH Pacific and KH Friends in the Distribution.
