Item 1.01                Entry into a Material Definitive Agreement.

On June 13, 2016, Celsion Corporation, a Delaware corporation (the “Company”), entered into a Securities Purchase Agreement (the “Purchase Agreement”) with an investor, pursuant to which the Company agreed to issue and sell, in a registered direct offering (the “Offering”), an aggregate of 2,311,764 shares (the “Shares”) of common stock, par value $0.01 per share, of the Company (“Common Stock”) at an offering price of $1.36 per share for gross proceeds of approximately $3.1 million before the deduction of the placement agent fee and offering expenses. The Shares are being offered by the Company pursuant to a registration statement on Form S-3 (File No. 333-206789), which was initially filed with the Securities and Exchange Commission (the “Commission”) on September 4, 2015 and was declared effective by the Commission on September 25, 2015 (the “Registration Statement”). In addition, the Company sold Pre-Funded Series B Warrants (the “Pre-Funded Series B Warrants”) to purchase 2,100,000 shares of Common Stock (and the shares of Common Stock issuable upon exercise of the Pre-Funded Series B Warrants), in lieu of shares of Common Stock to the extent that the purchase of Common Stock would cause the beneficial ownership of the Purchaser, together with its affiliates and certain related parties, to exceed 9.99% of our Common Stock.

In a concurrent private placement (the “Private Placement”), the Company agreed to issue to the investor Series A warrants, each to purchase 0.5 share of Common Stock, Series C warrants, each to purchase one share of Common Stock and Series D warrants, each to purchase 0.5 share of Common Stock (the “Warrants” and collectively with the Shares and the Pre-Funded Series B Warrants, the “Securities”). The Series A warrants are initially exercisable six months following issuance, and terminate five and one-half years following issuance. The Series C warrants are initially exercisable six months following issuance, and terminate one year following issuance. The Series D warrants only become exercisable ratably upon the exercise of the Series C warrants, are initially exercisable six months following issuance, and terminate five and one-half years following issuance. The Warrants have an exercise price of $1.40 per share and are exercisable to purchase an aggregate of 8,823,528 shares of Common Stock. Subject to limited exceptions, a holder of a Warrant will not have the right to exercise any portion of its warrants if the holder, together with its affiliates, would beneficially own in excess of 4.99% of the number of shares of Common Stock outstanding immediately after giving effect to such exercise (the “Beneficial Ownership Limitation”); provided, however, that upon 61 days’ prior notice to the Company, the holder may increase or decrease the Beneficial Ownership Limitation, provided that in no event shall the Beneficial Ownership Limitation exceed 9.99%.

The Warrants and the shares of our Common Stock issuable upon the exercise of the Warrants are not being registered under the Securities Act of 1933, as amended (the “Securities Act”), are not being offered pursuant to the Registration Statement and are being offered pursuant to the exemption provided in Section 4(a)(2) under the Securities Act and Rule 506(b) promulgated thereunder. We will be required to file a registration statement on Form S-3 within 45 calendar days of the issuance of the Warrants to provide for the resale of the shares of Common Stock issuable upon the exercise of the Warrants and will be obligated to use our commercially reasonable efforts to keep such registration statement effective until the earliest of (i) the date on which all of the shares of commons stock issuable upon the exercise of the Warrants have been sold under the registration statement or Rule 144 under the Securities Act, (ii) the date on which the shares of Common Stock issuable upon the exercise of the Warrants may be sold without volume or manner-of-sale restrictions pursuant to Rule 144 under the Securities Act and (iii) the termination of the Warrants.

The closing of the Offering and the Private Placement is subject to satisfaction of customary closing conditions set forth in the Purchase Agreement and is currently expected to occur on or about June 16, 2016. The Purchase Agreement also contains representations, warranties, indemnification and other provisions customary for transactions of this nature. Under the Purchase Agreement, the Company is prohibited, for a period of six months after the closing, from effecting or entering into an agreement to issue Common Stock or any other securities that are at any time convertible into, or exercisable or exchangeable for, or otherwise entitle the holder thereof to receive, Common Stock to the extent such issuance or sale involves certain variable conversion, exercise or exchange prices or such agreement provides for sale of securities at a price to be determined in the future.

On June 6, 2016, the Company entered into a Engagement Agreement (the “Engagement Agreement”) with H.C. Wainwright & Co. pursuant to which the Company engaged H.C. Wainwright & Co. as the sole placement agent in connection with the Offering and the Private Placement. The placement agent is not purchasing or selling any Securities the Company is selling but has agreed to use it reasonable best efforts to arrange for the sale of the Securities. The Company agreed to pay the placement agent a placement agent fee in cash equal to 6.5% of the gross proceeds from the sale of the Securities and reimburse the expenses of the placement agent for up to $50,000 for its legal fees and expenses in connection with this offering and up to $10,000 for its other out-of-pocket expenses in connection with this offering. The Engagement Agreement also contains representations, warranties, indemnification and other provisions customary for transactions of this nature.
