LINE OF CREDIT AND LONG-TERM DEBT

Credit and Guaranty Agreement and Revolving Credit Facility with Encina Business Credit, LLC

Effective February 1, 2017, we, Vertex Operating, and substantially all of our other operating subsidiaries, other than E-Source Holdings, LLC ("E-Source", provided that E-Source is no longer in operations and we no longer undertake dismantling, demolition, decommission and marine salvage services), entered into a Credit Agreement (the “EBC Credit Agreement”) with Encina Business Credit, LLC as agent (the “Agent” or “EBC”) and Encina Business Credit SPV, LLC and CrowdOut Capital LLC as lenders thereunder (the “EBC Lenders”). Pursuant to the EBC Credit Agreement, and the terms thereof, the EBC Lenders agreed to loan us up to $20 million, provided that the amount outstanding under the EBC Credit Agreement at any time cannot exceed 50% of the value of the operating plant facilities and related machinery and equipment owned by us (not including E-Source).

Amounts borrowed under the EBC Credit Agreement bear interest at 12%, 13% or 14% per annum, based on the ratio of (a) (i) consolidated EBITDA for such applicable period minus (ii) capital expenditures made during such period, minus (iii) the aggregate amount of income taxes paid in cash during such period (but not less than zero) to (b) the sum of (i) debt service charges plus (ii) the aggregate amount of all dividend or other distributions paid on capital stock in cash for the most recently completed 12 month period (which ratio falls into one of the three following tiers: less than 1 to 1; from 1 to 1 to less than 1.45 to 1; or equal to or greater than 1.45 to 1, which together with the value below, determines which interest rate is applicable) and average availability under the Revolving Credit Agreement (defined below) (which falls into two tiers: less than $2.5 million and greater than or equal to $2.5 million, which together with the calculation above, determines which interest rate is applicable), as described in greater detail in the EBC Credit Agreement (increasing by 2% per annum upon the occurrence of an event of default). Interest on amounts borrowed under the EBC Credit Agreement is payable by us in arrears, on the first business day of each month, beginning on the first business day of the first full month following the closing, together with required $75,000 monthly principal repayments. We also have the right to make voluntary repayments of the amount owed under the EBC Credit Agreement in amounts equal to or greater than $100,000, from time to time. The interest rate is 12% at March 31, 2019.

The EBC Credit Agreement terminates on February 1, 2020, on which date we are required to repay the outstanding balance owed thereunder and any accrued and unpaid interest thereon. As a result, the debt is classified as a current liability at March 31, 2019.

The amounts borrowed under the EBC Credit Agreement are guaranteed by us and our subsidiaries, other than E-Source, pursuant to a Guaranty and Security Agreement (the “Guaranty and Security Agreement”), whereby we also pledged substantially all of our assets and all of the securities of our subsidiaries (other than E-Source) as collateral securing the amount due under the terms of the EBC Credit Agreement. We also provided EBC mortgages on our Marrero, Louisiana, and Columbus, Ohio facilities to secure the repayment of outstanding amounts and agreed to provide mortgages on certain other real property to be delivered post-closing. The post-closing mortgage properties provided were in Baytown, Pflugerville and Corpus Christi, Texas.

The EBC Credit Agreement contains customary representations, warranties and requirements for the Company to indemnify the EBC Lenders and their affiliates. The EBC Credit Agreement also includes various covenants (positive and negative) binding upon the Company, including, prohibiting us from undertaking acquisitions or dispositions unless they meet the criteria set forth in the EBC Credit Agreement, not incurring any capital expenditures in an amount exceeding $3 million in any fiscal year that the EBC Credit Agreement is in place, and requiring us to maintain at least $2.5 million of borrowing availability under the Revolving Credit Agreement (defined below) in any 30 day period.

The EBC Credit Agreement includes customary events of default for facilities of a similar nature and size as the EBC Credit Agreement, including if an event of default occurs under any agreement evidencing $500,000 or more of indebtedness of the Company; we fail to make any payment when due under any material agreement; subject to certain exceptions, any judgment is entered against the Company in an amount exceeding $500,000; and also provides that an event of default occurs if a change in control of the Company occurs, which includes if (a) Benjamin P. Cowart, the Company’s Chief Executive Officer, Chairman of the Board and largest shareholder and Chris Carlson, the Chief Financial Officer of the Company, cease to own and control legally and beneficially, collectively, either directly or indirectly, equity securities in Vertex Energy, Inc., representing more than 15% of the combined voting power of all securities entitled to vote for members of the board of directors or equivalent on a fully-diluted basis, (b) the acquisition of ownership, directly or indirectly, beneficially or of record, by any person or group of securities representing more than 30% of the aggregate ordinary voting power represented by the issued and outstanding securities of Vertex Energy, Inc., or (c) during any period of 12 consecutive months, a majority of the members of the board of directors of the Company cease to be composed of individuals (i) who were members of that board or equivalent governing body on the first day of such period, (ii) whose election or nomination to that board or equivalent governing body was approved by individuals referred to in clause (i) above constituting at the time of such election or nomination at least a majority of that board or equivalent governing body or (iii) whose election or nomination to that board or other equivalent governing body was approved by individuals referred to in clauses (i) and (ii) above constituting at the time of such election or nomination at least a majority of that board or equivalent governing body (collectively “Events of Default”). An event of default under the Revolving Credit Agreement (defined below), is also an event of default under the EBC Credit Agreement.

Effective February 1, 2017, we, Vertex Operating and substantially all of our operating subsidiaries, other than E-Source, entered into a Revolving Credit Agreement (the “Revolving Credit Agreement” and together with the EBC Credit Agreement, the "Credit Agreements") with Encina Business Credit SPV, LLC as lender (“Encina”) and EBC as the administrative agent. Pursuant to the Revolving Credit Agreement, and the terms thereof, Encina agreed to loan us, on a revolving basis, up to $10 million, subject to the terms of the Revolving Credit Agreement and certain lending ratios set forth therein, which provide that the amount outstanding thereunder cannot exceed an amount equal to the total of (a) the lesser of (A) the value (as calculated in the Revolving Credit Agreement) of our inventory which are raw materials or finished goods that are merchantable and readily saleable to the public in the ordinary course of our business (“EBC Eligible Inventory”), net of certain inventory reserves, multiplied by 85% of the appraised value of EBC Eligible Inventory, or (B) the value (as calculated in the Revolving Credit Agreement) of EBC Eligible Inventory, net of certain inventory reserves, multiplied by 65%, subject to a ceiling of $4 million, plus (b) the face amount of certain accounts receivables (net of certain reserves applicable thereto) multiplied by 85% (subject to adjustment as provided in the Revolving Credit Agreement); minus (c) the then-current amount of certain reserves that the agent may determine necessary for the Company to maintain. At March 31, 2019, the maximum amount available to be borrowed was $2,862,056, based on the above borrowing base calculation.

Amounts borrowed under the Revolving Credit Agreement bear interest, subject to the terms of the Revolving Credit Agreement, at the one month LIBOR interest rate then in effect, subject to a floor of 0.25% (which interest rate is currently approximately 2.49% per annum), plus an additional 6.50% per annum (increasing by 2% per annum upon the occurrence of an event of default), provided that under certain circumstances amounts borrowed bear interest at the higher of (a) the “prime rate”; (b) the Federal Funds Rate, plus 0.50%; and (c) the LIBOR Rate for a one month interest period, plus 1.00%. Interest on amounts borrowed under the Revolving Credit Agreement is payable by us in arrears, on the first business day of each month, beginning on the first business day of the first full month following the closing.

The Revolving Credit Agreement terminates on February 1, 2020, on which date we are required to repay the outstanding balance owed thereunder and any accrued and unpaid interest thereon. As a result, the debt is classified as a current liability at March 31, 2019.

The amounts borrowed under the Revolving Credit Agreement are guaranteed by us and our subsidiaries, other than E-Source, pursuant to a separate Guaranty and Security Agreement, similar to the EBC Credit Agreement, described in greater detail above. We also provided Encina mortgages on our Marrero, Louisiana, and Columbus, Ohio facilities to secure the repayment of outstanding amounts.

The Revolving Credit Agreement contains customary representations, warranties and requirements for the Company to indemnify Encina and its affiliates. The Revolving Credit Agreement also includes various covenants (positive and negative) binding upon the Company, including, prohibiting us from undertaking acquisitions or dispositions unless they meet the criteria set forth in the Revolving Credit Agreement, not incurring any capital expenditures in amount exceeding $3 million in any fiscal year that the Revolving Credit Agreement is in place, and requiring us to maintain at least $2.5 million of borrowing availability under the Revolving Credit Agreement in any 30 day period.

The Revolving Credit Agreement includes customary events of default for facilities of a similar nature and size as the Revolving Credit Agreement, including the same Events of Default as are described above under the description of the EBC Credit Agreement.

The principal balances of the EBC Credit Agreement and the Revolving Credit Agreement as of March 31, 2019 are $15,125,000 and $6,370,510, respectively. Since these agreements terminate on February 1, 2020, the debt is classified as a current liability at March 31, 2019.
