On November 22, 2010, EDGAR Online, Inc. (the “Company”) completed the transactions contemplated by the Agreement and Plan of Merger (the “Merger Agreement”), dated as of June 23, 2010, among the Company, UBM Acquisition Corp., a Washington corporation and a wholly owned subsidiary of the Company (“Acquisition Sub”), and UBmatrix, Inc., a Washington corporation (“UBmatrix”). As such, upon the terms and subject to the conditions of the Merger Agreement, Acquisition Sub merged with and into UBmatrix with UBmatrix surviving as a subsidiary of the Company (the “Merger”). At the effective time of the Merger, all of the outstanding shares of capital stock of UBmatrix were converted into the right to receive an aggregate of 74,379 shares of the Company’s Series C Preferred Stock (the “Series C Preferred Stock”) and an aggregate of 2,685,088 shares of the Company’s common stock (the “Common Stock”). Of these shares, all of the shares of Series C Preferred Stock and 1,063,046 shares of the Common Stock are issuable at closing, while approximately 1,622,042 shares of the Common Stock are being paid into escrow to secure the post-closing indemnification obligations of the UBmatrix stockholders.

Information regarding the Series C Preferred Stock and Common Stock issued in the Merger set forth in Item 2.01 is incorporated in this Item 3.02.

Also on November 22, 2010, the Company sold 12,637 shares of Series C Preferred Stock to certain shareholders of UBmatrix pursuant to that certain Series C Preferred Stock Purchase Agreement (the “Purchase Agreement”), dated June 23, 2010, between the Company and such shareholders. The aggregate purchase price for such shares was $2,000,000 in cash.

The shares of Series C Preferred Stock and the Common Stock issued to the shareholders of UBmatrix in connection with the Merger, and the shares of Series C Preferred Stock sold under the Purchase Agreement, have been issued in a private placement exempt from registration pursuant to Section 4(2) of the Securities Act of 1933, as amended.

Each share of Series C Preferred Stock is convertible into a number of shares of the Common Stock determined by dividing the sum of the purchase price per share plus accrued dividends by an initial conversion price of $1.4481 per share, subject to adjustment. The holders of the Series C Preferred Stock shall be entitled to the number of votes equal to the number of shares of common stock into which such holder’s Series B Preferred Stock are convertible. The Series C Preferred Stock contains a compounding, cumulative 11.66% per annum paid-in-kind dividend payable upon conversion of the Series C Preferred Stock. Following January 28, 2015, the dividend shall no longer accrue unless declared by the Board of Directors of the Company.

The Certificate of Designation with respect to the Series C Preferred Stock is filed herewith as Exhibit 3.1 and is incorporated herein by reference.
