This Amendment No. 6 to Schedule 13D amends the Schedule 13D originally filed with the Securities and Exchange Commission (the “SEC”) on December 15, 2011, as amended by Amendment No. 1 filed on June 15, 2012, Amendment No. 2 filed on March 15, 2013, Amendment No. 3 filed on January 17, 2014, Amendment No. 4 filed on January 28, 2014 and Amendment No. 5 filed on March 4, 2014 (as amended, the “Schedule 13D”). Capitalized terms not otherwise defined herein shall have the meaning ascribed thereto in the Schedule 13D.

Item 4 is hereby supplemented and amended by the following additional information:

On March 5, 2014, the Issuer, MTS Markets International, Inc. (“MTS”), an affiliate of the London Stock Exchange Group, and MMI Newco Inc., a wholly-owned subsidiary of MTS (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”). On the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into the Issuer, with the Issuer continuing as the surviving corporation and a wholly-owned subsidiary of MTS (the “Merger”). As disclosed by the Issuer, the aggregate cash consideration (the “Merger Consideration”) is approximately $15 million according to the terms of the Merger Agreement and subject to certain adjustments described therein.

Pursuant to the Merger Agreement, MTS will place $1.5 million of proceeds from the sale of the shares pursuant to the Merger into escrow to cover the purchase price adjustment and certain potential indemnity claims. In the absence of claims, these funds will be released to the Series E-2 stockholders of the Issuer, including the Reporting Persons, in increments of $500,000 beginning on the first anniversary of closing and continuing on the 18 and 24 month anniversaries of closing. In addition, from $100,000 up to $200,000 will be held by a stockholder representative as a reserve for expenses incurred in connection with such person’s duties as a stockholder representative.

In connection with the Merger Agreement, certain of the Issuer’s stockholders, including the Reporting Persons, have executed a Written Consent of Certain Stockholders of Bonds.com Group, Inc. (the “Stockholder Consent”) on March 12, 2014, pursuant to which those stockholders, including the Reporting Persons, have affirmatively approved the Merger Agreement and the transactions contemplated thereby. In addition, pursuant to the Stockholder Consent, among other things, the Reporting Persons have agreed not to transfer, at any time prior to the effective time of the Merger, any shares of the Issuer’s capital stock held by the Reporting Persons.

If the Merger is consummated, the outstanding shares of common stock will cease to be registered under the Exchange Act, and the Issuer will become a wholly-owned subsidiary of MTS.

The Reporting Persons previously announced certain potential proposals regarding a possible change of control transaction or other business combination or refinancing transaction involving the Issuer. In light of the Issuer’s announcement of the pending Merger, the Reporting Persons have ceased their discussions with the Issuer regarding such a change of control transaction or other business combination or refinancing transaction other than the transactions contemplated by the Merger Agreement. The Reporting Persons reserve the right to change their plans or intentions and to take any and all actions that they may deem appropriate to maximize the value of their investment in the Issuer in light of their general investment policies, market conditions, subsequent developments affecting the Issuer and the general business and future prospects of the Issuer.

The foregoing description of the Stockholder Consent does not purport to be a complete description and is qualified in its entirety by reference to such document. A copy of the Stockholder Consent is attached hereto as Exhibit 99.1 and is incorporated herein by reference. References to, and descriptions of, the Merger Agreement as set forth in this Item 4 are qualified in their entirety by reference to the Merger Agreement filed as Exhibit 1.1 to the Issuer’s current report on Form 8-K filed with the SEC on March 7, 2014 which is incorporated in its entirety in this Item 4.

(a) The aggregate number and percentage of the class of securities identified pursuant to Item 1 beneficially owned by the Reporting Person is stated in Items 11 and 13 on the cover page herein.

(b) Number of shares as to which the Reporting Person has:
