Item 1.01 Entry into a Material Definitive Agreement.

On June 23, 2015 (the “Closing Date”), Surna, Inc. (the “Company”) entered into a security agreement (the “Security Agreement”) with Kind Agrisoft, LLC (“Kind”), pursuant to which Kind granted the Company a security interest in all of its intellectual property and accounts receivable (the “Assets”) to secure the payment of all past and future loans from the Company, which, as of the Closing Date, equaled $272,217.66 (the “Debt Obligations”).

Prior to the Closing Date, the Company entered into a memorandum of understanding (the “MOU”) with Kind pursuant to which Kind agreed to make an initial payment of not less than $25,000 (the “Initial Payment”) to the Company no later than 2 business days after the Closing Date. The Initial Payment will be applied to the Debt Obligations. Additionally, as agreed upon in the MOU, the remaining amount of the Debt Obligations shall bear interest at a rate of 8% per annum and payable to the Company in such amounts and on such dates as follows: (i) $40,000 on the first day of the fourth month after the Initial Payment and (ii) $50,000, or such lesser amount necessary to make the final payment, every three months thereafter until the Debt Obligations are fully satisfied (collectively, the “Payment Schedule”). In the event Kind fails to comply with the Payment Schedule and such default is not cured within ten business days after notice from the Company, then all amounts shall be accelerated and immediately payable to the Company.

Pursuant to the MOU, the Company and Kind agreed (i) that the Company will subordinate its lien against the Assets, if such subordination is required by Kind’s lenders, when the Debt Obligations is less than $100,000, (ii) Kind will pay the Company a 1% quarterly royalty on its EBITDA (earnings before interest taxes depreciation and amortization), which payments, together with the Debt Obligations, will not exceed $600,000, and (iii) that the parties will negotiate a co-development and licensing agreement.

Previously, the Company entered into an agreement to acquire (the “Proposed Acquisition”) from Jim Willet and Forbeez Capital, LLC (collectively, the “Sellers”) 66% of the total membership interests in Agrisoft Development Group (“Agrisoft”). In connection with the Proposed Acquisition, the Company advanced a total of $260,000 to Agrisoft, which advances were secured by Agrisoft’s assets. Pursuant to the MOU, Kind agreed to purchase Agrisoft’s assets and repay any advances made by the Company to Agrisoft. Accordingly, the Debt Obligations represent the outstanding advances, plus accrued but unpaid interest, made by the Company as of the Closing Date. In connection with Kind’s purchase of Agrisoft’s assets, the Company will not proceed with the Proposed Acquisition at this time.

The descriptions of the Security Agreement and MOU are not complete and are qualified by the full text of the Security Agreement and MOU, which are attached as Exhibits 10.1 and 10.2, respectively, and incorporated by reference herein.
