Item 1.02 Termination of a Material Definitive Agreement.

Item 3.03 below is incorporated herein by reference.

Item 2.01 Completion of Acquisition or Disposition of Assets.

As previously disclosed, on April 6, 2014, Vocus, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with GTCR Valor Companies, Inc., a Delaware corporation (“Parent”), and GTCR Valor Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Parent (“Purchaser”), providing for the merger of Purchaser with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Parent. In accordance with the terms of the Merger Agreement, on May 30, 2014 (the “Closing Date”), the Merger was consummated. At the effective time of the closing of the Merger (the “Effective Time”), each share of the Company’s common stock, par value $0.01 per share (the “Common Stock”), issued and outstanding immediately prior to the Effective Time (other than Shares held by the Company as treasury stock or held by Parent, Purchaser or any other direct or indirect wholly owned subsidiary of Parent) was automatically converted into the right to receive $18.00 per share in cash, without interest (the “Per Share Merger Consideration”).

The foregoing description of the Merger and the Merger Agreement does not purport to be complete in all respects and is qualified in its entirety by reference to the Merger Agreement, which was attached as Exhibit 2.1 to the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on April 7, 2014 and is incorporated herein by reference.

A copy of the joint press release issued by the Company, Parent and Purchaser on May 30, 2014 announcing the completion of the Merger is attached hereto as Exhibit 99.1 and incorporated herein by reference.

Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On May 30, 2014, the Company notified the NASDAQ Global Select Market (“NASDAQ”) of the completion of the Merger and requested that (i) trading of the Common Stock, together with the associated Series B Junior Participating Preferred Stock purchase rights (the “Rights”), on NASDAQ be suspended as of the close of business on May 30, 2014 and (ii) NASDAQ file with the SEC a Notification of Removal from Listing and/or Registration under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on Form 25 to delist and deregister the Common Stock and associated Rights. As of the close of business on May 30, 2014, the Common Stock, together with the associated Rights, which traded under the symbol “VOCS,” ceased trading on, and is being delisted from, NASDAQ. The Company intends to file with the SEC a certification on Form 15 under the Exchange Act requesting the termination of the registration of the Common Stock, together with the associated Rights, under Section 12(g) of the Exchange Act and the suspension of the Company’s reporting obligations under Sections 13 and 15(d) of the Exchange Act.

The information set forth under Item 2.01 of this Current Report on Form 8-K is incorporated into this Item 3.01 by reference.

Item 3.03 Material Modification to Rights of Security Holders.

Reference is hereby made to that certain Rights Agreement dated as of May 13, 2013, by and between the Company and American Stock Transfer & Trust Company, LLC, as rights agent, as amended by that certain First Amendment, dated as of April 6, 2014 (as amended, the “Rights Agreement”). Pursuant to Section 1(l) of the Rights Agreement, the Rights Agreement expires and terminates immediately prior to the Effective Time. Accordingly, the Rights Agreement has terminated and is of no further force or effect. Furthermore, the preferred share purchase rights granted under the Rights Agreement, each representing the right to purchase one one-thousandth share of Series B Junior Participating Preferred Stock of the Company, have expired and are no longer outstanding.
