Item 1.01.   Entry into a Material Definitive Agreement.


On December 13, 2012, Navidea Biopharmaceuticals, Inc. (the “Company”) agreed to amend the terms of the Series X Warrant to purchase 8,333,333 shares (the “Shares”) of the Company’s common stock, $.001 par value (“Common Stock”), issued by the Company to Platinum-Montaur Life Sciences, LLC (“Montaur”) on April 16, 2008, which Series X Warrant was amended and restated on or about July 24, 2009, and then replaced on or about July 2, 2012, to reflect a change in the Company's name (as so amended and replaced the “Series X Warrant”). The Amendment to the Series X Warrant (the “Amendment”) provides for the expiration on December 31, 2013, of the term during which Montaur has the right subscribe for and purchase the Shares, as opposed to April 16, 2013, as set forth in the original Series X Warrant.


Additionally, and also effective December 13, 2012, the Company, Montaur, and Platinum Partners Value Arbitrage Fund, L.P. (“Platinum”) entered into a waiver agreement (the “Waiver”) pursuant to which Montaur and Platinum, as the sole holders of the Company’s Series B Convertible Preferred Stock (“Series B Stock”), and the Company, agreed to irrevocably waive the operation of the provisions set forth in Section 9(a) of the Certificate of Designations, Voting Powers, Preferences, Limitations, Restrictions, and Relative Rights of Series B Convertible Preferred Stock (the “Certificate”) which provide that all outstanding shares of Series B Stock shall automatically convert into shares of Common Stock on December 31, 2012. The Waiver will remain in effect until December 31, 2013, upon which date all outstanding shares of Series B Stock will automatically convert into Common Stock pursuant to the terms of the Certificate.


The foregoing descriptions of the Amendment and the Waiver are qualified in their entirety by reference to the full text of the Amendment and the Waiver, copies of which are attached hereto as Exhibit 10.1 and Exhibit 10.2, respectively, and each of which is incorporated herein by reference.


Item 8.01.   Other Events.


On December 18, 2012, the Company issued a press release announcing that it has submitted a Marketing Authorization Application (“MAA”) for its investigational radiopharmaceutical Lymphoseek® (technetium Tc 99m tilmanocept) injection, a novel intraoperative lymphatic mapping (“ILM”) agent, to the European Medicines Agency. The Company is seeking marketing approval for Lymphoseek in the European Union for use in ILM, a surgical oncology procedure in which lymph nodes draining the area around a tumor are identified and biopsied to determine if cancer has spread to the lymph nodes. The Lymphoseek MAA has proposed the use of the agent in general lymphatic mapping not restricted to any particular solid tumor type.


A copy of the complete text of the Company’s December 18, 2012, press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.
