The persons filing this Schedule 13D (collectively, the “Reporting Persons”) are:

Mr. DeGeorge is the Chief Executive Officer of LPL Group, Inc., LPL Investment Group, Inc., LPL Management Group, Inc. and DeGeorge Holdings Ltd. The principal office of each of these companies is 140 Intracoastal Pointe Drive, Suite 410, Jupiter, Florida 33477, and their principal business is investment management. Mr. DeGeorge is a citizen of the United States of America.

b.	DeGeorge Holdings Three LLC is Delaware limited liability company, whose address is 140 Intracoastal Pointe Drive, Suite 410, Jupiter, Florida 33477. DeGeorge Holdings Three LLC is an affiliate of Mr. DeGeorge. The principal business of DeGeorge Holdings Three LLC is investment management.

During the last five years, none of the Reporting Persons have been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors). During the last five years, none of the Reporting Persons have been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction making such Reporting Person subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

See Item 4.

Item 4. Purpose of Transaction.

On August 16, 2010, Lawrence F. DeGeorge and certain other shareholders, who, together, owned over 90% of the outstanding shares of each class of the Issuer’s outstanding equity (the “Majority Shareholders”), filed a Rule 13e-3 Transaction Statement under Section 13(e) of the Securities Exchange Act of 1934 (the “Schedule 13E-3”) announcing their intention to effect a short-form merger (the “Merger”) under Section 7-111-104 of the Colorado Business Corporation Act (the “CBCA”). On August 16, 2010, the Majority Shareholders filed Amendment No. 1 to the Schedule 13E-3 and on September 14, 2010, they filed Amendment No. 2 to the Schedule 13E-3.

Pursuant to the terms of the Contribution Agreement by and among GSLD Holdings, Inc. (“Holdings”), Mr. DeGeorge and certain other shareholders, dated August 13, 2010 (the “Contribution Agreement”), Mr. DeGeorge agreed to contribute 7,393,941 shares of Common Stock and 134,554,815 shares of the Issuer’s Series D preferred stock (the “Preferred Stock,” and together with the Common Stock, the “Stock”) to Holdings immediately prior to the consummation of the Merger. In total, Mr. DeGeorge contributed 141,948,756 shares of the Issuer’s Stock pursuant to the Contribution Agreement. The 80,130,431 shares of stock beneficially held by Mr. DeGeorge through DeGeorge Holdings Three LLC were excluded from the Contribution Agreement.

Schedule 13D

Page 5 of 8

On September 23, 2010, the Merger became effective pursuant to a Plan of Merger dated September 16, 2010 (the “Plan of Merger”) and Section 7-111-104 of the CBCA, and Holdings was merged with and into the Issuer, with the Issuer as the surviving corporation (in such capacity, the “Surviving Corporation”). Upon the consummation of the Merger, each issued and outstanding share of the Issuer was converted into the right to receive shares of the Surviving Corporation at a conversion ratio of one thousand five hundred (1,500) shares of the Issuer for every one (1) share of the Surviving Corporation. No fractional shares were issued. Instead, holders who were otherwise entitled to receive fractional shares became entitled to receive an amount in cash, without interest, equal to two United States cents (US$0.02) per share; however, all stockholders who are entitled to receive cash for their shares of Stock will receive at least one United States dollar (US$1.00).

Under the CBCA, no action was required by the board of directors of the Issuer or the shareholders of the Issuer, other than that of Holdings, for the Merger to become effective. Holders of the Issuer’s Stock were not entitled to vote their shares with respect to the Merger; however, holders of the Issuer’s Preferred Stock are entitled to certain appraisal rights under the CBCA. The Common Stock and Preferred Stock constitute the only classes of capital stock of the Issuer that, in the absence of Section 7-111-104 of the CBCA, would have been entitled to vote on the Merger.

The Schedule 13E-3, including all exhibits attached thereto and all amendments, previously filed by Holdings and the Majority Shareholders, is incorporated by reference into this Item 4. The Contribution Agreement, dated August 13, 2010, and the Plan of Merger, dated September 16, 2010, are also incorporated by reference herein, and any description thereof is qualified in its entirety by reference thereto.

Item 5. Interest in Securities of the Issuer.

As of the date of the filing of this Schedule 13D, Mr. DeGeorge is deemed to beneficially own 148,052 shares of Common Stock of the Issuer. Mr. DeGeorge’s beneficial ownership represents 76.88% of the issued and outstanding Common Stock of the Issuer, assuming (i) conversion by DH3 of a promissory note in favor of DH3, which is convertible upon its terms and the terms of a Senior Secured Revolving Credit Agreement, dated November 6, 2008, into shares of Series D Preferred Stock and subsequent conversion of the resulting Series D Preferred Stock into shares of Common Stock, (ii) conversion by DH3 of Warrants convertible into shares of Series D Preferred Stock, which are in turn convertible on a one-to-one basis into shares of Common Stock, and (iii) conversion by Mr. DeGeorge of his own shares of Series D Preferred Stock into shares of Common Stock.

Assuming full conversion as discussed above, Mr. DeGeorge would have the sole power to vote and has sole dispositive rights with regard to 94,632 shares of Common Stock, and shared power to vote and shared dispositive rights with regard to 53,420 shares of Common Stock held by DH3, for total voting and dispositive power of 148,052 shares of Common Stock.

c.	See Item 4.

d.	Not applicable.

e.	Not applicable.

Except as described in Item 4, none of the Reporting Persons have effected any additional transactions with respect to the Common Stock of the Company during the past 60 days.
