Item 1.01              Entry into a Material Definitive Agreement.

On June 27, 2014, IGI Laboratories, Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Roth Capital Partners, LLC and Oppenheimer & Co., as representatives of the several underwriters named therein (the “Underwriters”), relating to the underwritten public offering and sale of up to an aggregate of 4,650,000 shares of the Company’s common stock, par value $0.01 (the “Shares”), at a price to the public of $5.00 per share (the “Offering”). The Company has also granted the underwriters a 30-day option to purchase up to an aggregate of 697,500 Shares to cover over-allotments, if any. The net proceeds to the Company from the sale of the Shares are expected to be approximately $21.7 million, after deducting underwriting discounts and commissions of 5.25%, or $0.2625 per share, and other estimated offering expenses payable by the Company, and assuming no exercise by the Underwriters of their over-allotment option.

The Offering is being made pursuant to the Company’s shelf registration statement on Form S-3 (Registration No. 333-196543), filed on June 5, 2014 with the Securities and Exchange Commission (the “SEC”) and declared effective by the SEC on June 16, 2014, and pursuant to the prospectus supplement and the accompanying prospectus describing the terms of the Offering, dated June 27, 2014. The Offering is expected to close on or about July 2, 2014, subject to customary closing conditions.

The Underwriting Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and the Underwriters, including for liabilities under the Securities Act of 1933, as amended, other obligations of the parties and termination provisions. The representations, warranties and covenants contained in the Underwriting Agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement and may be subject to limitations agreed upon by the contracting parties. Subject to certain exceptions, the Company, the Company’s directors, executive officers and certain of the Company’s stockholders also agreed not to sell or transfer any shares of common stock of the Company for 45 days (90 days for the Company) after June 27, 2014 without first obtaining the consent of Roth Capital Partners, LLC and Oppenheimer & Co.

A copy of the Underwriting Agreement is attached hereto as Exhibit 1.1 and is incorporated herein by reference. The foregoing description of the terms of the Underwriting is qualified in its entirety by reference to such exhibit. A copy of the opinion of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C. relating to the legality of the issuance and sale of the Shares is attached as Exhibit 5.1 hereto.
