Item 3.

Source and Amount of Funds or Other Consideration

On March 7, 2008, AVANT announced the closing of a business combination transaction (the “Merger”) pursuant to a certain Agreement and Plan of Merger, dated October 19, 2007 (the “Merger Agreement”) by and among AVANT, Callisto Merger Corporation (“Callisto”), a wholly-owned subsidiary of AVANT, and Celldex Therapeutics, Inc. (“Celldex”).  Pursuant to the terms of the Merger Agreement, Callisto merged with and into Celldex, with Celldex as the surviving company and a wholly-owned subsidiary of AVANT.  Medarex owned approximately 60% of Celldex prior to the Merger and, as a result of the Merger and pursuant to the terms of the Merger Agreement, Medarex received approximately 4.9 shares of AVANT’s Common Stock in exchange for each share it held in Celldex prior to the Merger, subject to adjustment to account for a 1-for-12 reverse stock split approved by AVANT’S board of directors on the closing date of the Merger Agreement.  As a result of the Merger and pursuant to the terms of the Merger Agreement, Medarex was issued 4,960,848 shares of AVANT Common Stock in exchange for the shares it previously held in Celldex and 351,691 shares of AVANT Common Stock in settlement of a prior dispute between Medarex and Celldex which obligation was assumed by AVANT in the Merger.

(9) a class of securities of AVANT becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or

 

(10) any action similar to any of those enumerated above.

 

Although there is no present intention to do so, the Reporting Person and/or any person named on Appendix A attached hereto may decide to make additional purchases or dispose of its Common Stock in the future either in the open market or in private transactions, subject to its or their evaluation of the AVANT’s business, prospects and financial condition, the market for the Common Stock, other opportunities available to the Reporting Person or any person named on Appendix A attached hereto, prospects for the respective business’ of the Reporting Person or any person named on Appendix A attached hereto, general economic conditions, money and stock market conditions and other future developments.

 

Depending upon the results of the reviews and the other factors mentioned above, the Reporting Person or any person named on Appendix A attached hereto, at any time, may decide to change its or his intention with respect to the acquisition and/or retention of shares of Common Stock, including, without limitation, a determination to increase, decrease or entirely dispose of its or his holdings of Common Stock, although neither the Reporting Person nor, to the knowledge of the Reporting Person, any of the persons named on Appendix A attached hereto has any current intention to do so.
