LINE OF CREDIT AND LONG-TERM DEBT

In September 2012, the Company entered into a credit agreement with Bank of America. Pursuant to the agreement, Bank of America agreed to loan the Company $8,500,000 in the form of a term loan and to provide the Company with an additional $10,000,000 in the form of a revolving line of credit.

In May 2014, the Company entered into an amended and restated credit agreement with Bank of America. The amended credit agreement amended and restated the prior credit agreement entered into with Bank of America in September 2012. Pursuant to the agreement, Bank of America agreed to loan the Company up to $20,000,000 in the form of a revolving line of credit, subject to certain terms and lending ratios, to be used for feedstock purchases and general corporate purposes. The line of credit bears interest at the option of the Company of either the lender's prime commercial lending rate then in effect between 1.25% and 2% per annum or the Bank of America LIBOR rate plus between 2.35% and 3% (both ranges dependent upon the Company's leverage ratio from time to time). Accrued and unpaid interest on the revolving note is due and payable monthly in arrears and all amounts outstanding under the revolving note are due and payable on May 2, 2017. The balance on the revolving line of credit was $0 at September 30, 2015.

The financing arrangement discussed above is secured by a first priority security interest in all of the assets and securities of our direct and indirect subsidiaries other than E-Source. The loan includes various covenants binding upon the Company, including, requiring that the Company comply with certain reporting requirements, provide notices of material corporate events and forecasts to Bank of America, and maintain certain financial ratios relating to debt leverage, consolidated EBITDA, maximum debt exposure, and minimum liquidity, including maintaining a ratio of quarterly consolidated EBITDA to certain fixed charges.

On May 2, 2014, the Company entered into a Credit and Guaranty Agreement with Goldman Sachs Bank USA. Pursuant to the agreement, Goldman Sachs Bank USA loaned the Company $40,000,000 in the form of a term loan. As set forth in the Credit Agreement, the Company has the option to select whether loans made under the Credit Agreement bear interest at (a) the greater of (i) the prime rate in effect, (ii) the weighted average of the rates on overnight Federal funds transactions with members of the Federal Reserve System plus ½ of 1%, (iii) the sum of (A) the Adjusted LIBOR Rate and (B) 1%, and (iv) 4.5% per annum; or (b) the greater of (i) 1.50% and (ii) the applicable ICE Benchmark Administration Limited interest rate, divided by (x) one minus, (y) the Adjusted LIBOR Rate. Interest on the Credit Agreement is payable monthly in arrears. Amortizing principal payments are due on the Credit Agreement Loan in the amount of $300,000 per fiscal quarter for June 30, 2014, September 30, 2014, December 31, 2014 and March 31, 2015, and $800,000 per fiscal quarter thereafter until maturity on May 2, 2019. The balance on the term loan was $23,200,000 at September 30, 2015.

The Goldman Sachs Bank USA financing arrangement is secured by all of the assets of the Company, but was subordinate to the aforementioned Bank of America credit agreement.

On March 26, 2015, we, Vertex Operating, and substantially all of our other subsidiaries (other than E-Source), Goldman Sachs Specialty Lending Holdings, Inc. (“Lender”) and Goldman Sachs Bank USA, as Administrative Agent and Collateral Agent for Lender (“Agent”), entered into a Second Amendment to Credit and Guaranty Agreement (the “Second Amendment”). The Second Amendment amended that certain Credit and Guaranty Agreement entered into between the parties dated as of May 2, 2014 and amended by the First Amendment to Credit and Guaranty Agreement entered into on December 5, 2014 (the “First Amendment” and the Credit and Guaranty Agreement as amended and modified by the First Amendment and Second Amendment, the “Credit Agreement”).

During the third quarter of 2014, various events of default had occurred and were continuing under the Credit Agreement and the parties entered into the Second Amendment to among other things, provide for the waiver of the prior defaults and to restructure certain covenants and other financial requirements of the Credit Agreement and to allow for our entry into the MidCap Loan Agreement (described below).

The amendments to the Credit Agreement effected by the Second Amendment include, but are not limited to:


•	Effecting various amendments to the Credit Agreement to substitute the name of MidCap Business Credit, LLC and the MidCap Loan Agreement (as described below) in place of Bank of America, NA (“BOA”), and the Company’s prior Credit Agreement with BOA.


•	Increasing the interest rate of certain outstanding loans made under the terms of the Credit Agreement by up to 2% per annum, based on the leverage ratio of debt to consolidated EBITDA of the Company.


•	Changing the calculation dates for certain fixed charge ratios required to be calculated pursuant to the terms of the Credit Agreement.


•	Changing how certain debt leverage ratios are calculated under the terms of the Credit Agreement.


•	Increasing the additional default interest payable upon the occurrence of an event of default under the Credit Agreement to 4% per annum (compared to 2% per annum for all other defaults) above the then applicable interest rate in the event we fail to make the Required Prepayment (as defined below).


•	Providing that no quarterly amortization payments would be due under the terms of the Credit Agreement for the quarters ended March 31, 2015 and June 30, 2015 (previously amortization payments of $800,000 per quarter were due for both such quarters).


•	Providing that we are not required to meet certain debt and leverage covenants for certain periods of fiscal 2015.


•	Requiring that we raise at least $9.1 million by June 30, 2015 through the sale of equity, and that we are required to pay such funds directly to the Lender as a mandatory pre-payment of the amounts outstanding under the Credit Agreement (the “Required Payment”), which required payment was paid in June 2015, as described below.

•

Changing certain of the required prepayment terms of the Credit Agreement, which require us to prepay the amounts owed under the Credit Agreement in an amount equal to 100% of the extent total consolidated debt exceeds (x) total consolidated EBITDA (as calculated pursuant to the agreement) multiplied by (y) the maximum debt leverage ratios described in the Credit Agreement, provided that no prepayments in connection with such requirements are required to be made through December 31, 2015.


•	Reducing the amount of allowable additional borrowings we can make under other debt agreements and facilities to $7 million in aggregate (including not more than $6 million under the MidCap Loan Agreement through December 31, 2015).


•	Changing certain fixed charge, leverage ratios and consolidated EBITDA calculations, definitions, and requirements relating to covenants under the Credit Agreement.

•

Changing the required amount of cash on hand and available borrowings under the MidCap Loan Agreement. We are required to have at least (a)$750,000 after the date of the Second Amendment and prior to June 30, 2015, (b) $1.5 million at any time after June 30, 2015 and prior to December 31, 2015, (c) $2 million at any time after December 31, 2015 and prior to June 30, 2016, (d) $2.5 million at any time after June 30, 2016 and prior to December 31, 2016, and (e) $3 million at any time after December 31, 2016.

The Lender also waived all of the prior defaults which the Lender had provided the Company notice of previously (which were all of the known defaults that existed at the time of the parties’ entry into the Second Amendment) and the Company and its subsidiaries provided a release in favor of the Lender and its representatives and assigns. We also agreed to pay the Agent a fee of $50,000 per year (including $50,000 paid upon our entry into the Second Amendment) as an administration fee; and pay the Agent certain prepayment fees in the event we prepay amounts outstanding under the Credit Agreement prior to March 26, 2018, provided no prepayment fee is due in connection with the Required Payment or certain other mandatory prepayments required under the terms of the Credit Agreement, subject to certain exceptions.

As additional consideration for the Lender agreeing to the terms of the Second Amendment, we granted Goldman, Sachs & Co., an affiliate of the Lender (such initial holder and its assigns, if any, the “Holder”) a warrant to purchase 1,766,874 shares of our common stock which was evidenced by a Common Stock Purchase Warrant (the “Lender Warrant”). The Lender Warrant was to expire on March 26, 2022 and originally had an exercise price equal to the lower of (x) $3.39583 per share; and (y) the lowest price per share at which we issue any common stock (or sets an exercise price for the purchase of common stock) between the date of our entry into the Lender Warrant and June 30, 2015. The Lender Warrant was exercisable by the Holder at any time after September 1, 2015, including pursuant to a cashless exercise. The Lender Warrant provided that in the event that, prior to June 30, 2015, we prepaid the amount owed under the Credit Agreement in an amount greater than $9.1 million (i.e., in an amount greater than the Required Payment) then the number of shares of common stock issuable upon exercise of the Lender Warrant is reduced by the pro rata amount by which the amount prepaid exceeds $9.1 million and is less than $15.1 million, provided that if prior to June 30, 2015 we prepaid at least $6 million in addition to the Required Payment the Lender Warrant automatically terminated.

On June 18, 2015, the Company entered into the Third Amendment to Credit and Guaranty Agreement (the “Third Amendment”), which amended the Credit Agreement (defined above). The amendments to the Credit Agreement effected by the Third Amendment include, but are not limited to:


•	Extending the time period pursuant to which we are required to make certain post-closing deliverables pursuant to the terms of the Credit Agreement.


•	Providing that we are not required to meet certain debt and leverage covenants for certain periods extending until March 31, 2016 (previously we were required to meet such covenants beginning with the quarter ended December 31, 2015).

•

Extending the date we are required to begin making required prepayments under the terms of the Credit Agreement, in an amount equal to 100% of the extent total consolidated debt exceeds (x) total consolidated EBITDA (as calculated pursuant to the agreement) multiplied by (y) the maximum debt leverage ratios described in the Credit Agreement, until March 31, 2016 (previously no payments were required to be made through December 31, 2015).

•

Reducing certain required consolidated EBITDA targets pursuant to the terms of the Credit Agreement to be more favorable to the Company, including reducing such targets to $250,000, $1.5 million, $4.25 million, $7.25 million and $9.5 million for the quarters ended September 30, 2015, December 31, 2015, March 31, 2016, June 30, 2016 and September 30, 2016 (and each quarter thereafter), respectively, compared to $3 million, $5.5 million, $8 million, $9 million and $10 million, respectively.


•	Extending the date we are required to begin meeting various leverage ratios and consolidated EBITDA targets as set forth in the Credit Agreement from December 31, 2015 and June 30, 2015, to March 31, 2016 and September 30, 2015, respectively.

As additional consideration for the Lender agreeing to the terms of the Third Amendment, we agreed to modify, pursuant to a First Amendment to Warrant, the terms of the Lender Warrant. Pursuant to the First Amendment to Warrant, we agreed to reduce the exercise price of the Lender Warrant to $2.778 per share (the 30 day volume weighted average price of our common stock as of the date of our entry into the Third Amendment) from $3.395828553 per share, and that in the event we issue any preferred stock, that the lowest exercise price associated with any warrants or similar convertible securities issued in connection with such preferred stock offering shall become the exercise price of the Lender Warrant; provided that, if the Company does not issue preferred stock on or prior to June 30, 2015, then the exercise price of the Lender Warrant would be reduced to the lowest closing price per share of our common stock on any date between March 26, 2015 and June 30, 2015.

Effective June 29, 2015, we repaid $15.1 million of the amount owed to the Lender under the Credit, and as a result, the Lender Warrant and rights thereunder were canceled and terminated.

On May 2, 2014, in connection with the closing of the Omega Refining acquisition, the Company assumed two capital leases totaling $3,154,860. Payments of $2,790,299 were made at closing and the balance was $364,561 at September 30, 2015.

The Company financed insurance premiums through various financial institutions bearing interest rates from 4% to 4.52%. All such premium finance agreements have maturities of less than one year and have a balance of $1,172,147 at September 30, 2015.

Effective March 27, 2015, the Company, Vertex Operating and all of the Company’s other subsidiaries other than E-Source and Golden State, entered into a Loan and Security Agreement with MidCap Business Credit LLC (“MidCap” and the “MidCap Loan Agreement”). Pursuant to the MidCap Loan Agreement, MidCap agreed to loan us up to the lesser of (i) $7 million; and (ii) 85% of the amount of accounts receivable due to us which meet certain requirements set forth in the MidCap Loan Agreement (“Qualified Accounts”), plus the lesser of (y) $3 million and (z) 50% of the cost or market value, whichever is lower, of our raw material and finished goods which have not yet been sold, subject to the terms and conditions of the MidCap Loan Agreement (“Eligible Inventory”), minus any amount which MidCap may require from time to time in order to over secure amounts owed to MidCap under the MidCap Loan Agreement, as long as no event of default has occurred or is continuing under the terms of the MidCap Loan Agreement. The requirement of MidCap to make loans under the MidCap Loan Agreement is subject to certain standard conditions and requirements.

The MidCap Loan Agreement contains customary representations, warranties, covenants, and events of default for facilities of similar nature and size as the MidCap Loan Agreement, and requirements for the Company to indemnify MidCap for certain losses.

We also entered into a Revolving Note (the “MidCap Note”) to evidence amounts borrowed from MidCap from time to time under the MidCap Loan Agreement. Interest on the MidCap Note accrues at a fluctuating rate equal to the aggregate of: (x) the prime rate then in effect, and (y) 1.75% per annum, or at such other rate mutually agreed on from time to time by the parties, based upon the greater of (i) any balance owing under the MidCap Note at the close of each day; or (ii) a minimum assumed average daily loan balance of $3 million. Interest is payable in arrears, on the first day of each month that amounts are outstanding under the MidCap Note. The balance on the revolving note was $659,893 at September 30, 2015.

On January 7, 2015, E-Source entered into a loan agreement with Texas Citizens Bank to consolidate various smaller debt obligations. The loan Agreement provides a term note in the amount of $2,201,372 that matures on January 7, 2020. Borrowings bear a fixed interest rate of 5.5% per annum and interest will be calculated from the date of each advance until repayment in full or maturity. The loan has 59 scheduled monthly payments of $45,147 which includes principal and interest. The loan is collateralized by all of the assets of E-Source. The balance on the term note was $2,045,500 at September 30, 2015.
