Omega of the Omega Acquired Assets, the assignment to and assumption by Louisiana Buyer from Omega of the Omega Assumed Liabilities and the transfer and assignment of all of the outstanding equity interests in Golden State to Bango Buyer shall be referred to herein as the "Initial Closing" and the date on which the Initial Closing occurs is referred to herein as the "Initial Closing Date".  The closing of the portion of the Transaction related to the sale and transfer by Bango Refining to Bango Buyer and the purchase and acquisition by Bango Buyer from Bango Refining of the Bango Acquired Assets and the assignment to and assumption by Bango Buyer from Bango Refining of the Bango Assumed Liabilities shall be referred to herein as the "Second Closing" and the date on which the Second Closing occurs is referred to herein as the "Second Closing Date".  For purposes of this Agreement each of the Initial Closing Date and the Second Closing Date is referred to herein as a "Closing Date." The Initial Closing shall occur on or before the later of April [1], 2014 or the third Business Day after the satisfaction or waiver of the conditions set forth in Section 6 (excluding conditions that, by their terms, cannot be satisfied until the Initial Closing Date but subject to the satisfaction or waiver of such conditions at the Initial Closing) that apply to the Initial Closing, or on such other date as is mutually acceptable to the Parties.  The Second Closing shall occur on the fifth Business Day after the satisfaction or waiver of the conditions set forth in Section 6 (excluding conditions that, by their terms, cannot be satisfied until the Second Closing Date but subject to the satisfaction or waiver of such conditions at the Second Closing) that apply to the Second Closing, or on such other date as is mutually acceptable to the Parties.  Except as otherwise provided in this Agreement, the failure to consummate the purchase and sale provided for in this Agreement on the date and time and at the place specified herein will not relieve any Party of any obligation under this Agreement.  Each Closing shall be effective as of the Effective Time with respect to such Closing.

(b)           Second Closing. In consideration of Bango Refining's sale, assignment and transfer of the Purchased Assets of Bango Refining and the performance by it of all of the terms, covenants and provisions of this Agreement on its part to be kept and performed, at the

23

Second Closing, Bango Buyer shall: (i) assume the Assumed Liabilities of Bango Refining; and (ii) cause Vertex to issue [a] subject to Section 5.01(e), 500,000 shares of the Closing Stock Consideration, which amount shall be deemed to be delivered upon delivery of stock certificates to such recipients as are designated by Sellers and whom are allowable under applicable Law representing such number of shares of Vertex Common Stock (as adjusted under Section 5.02) and [b] 1,000,000 shares of the Closing Stock Consideration to the Escrow Agent as provided in Section 5.03(b) below.

(c)           Allocation of Proceeds. The Closing Cash Payment and the Closing Stock Consideration shall be allocated among Sellers, the Escrow Agent and such other third party payees as set forth on Schedule 5.01 (as such Schedule may be updated in connection with each Closing), and the Closing Stock Consideration shall be registered in the name of each such recipient, and bearing the legends and restrictions set forth in Section 9.18(c) below.  Buyers shall be entitled to conclusively rely on such Schedule in paying the Closing Cash Payment and in issuing such Closing Stock Consideration.  The Closing Stock Consideration is subject to further adjustment as provided in Section 5.02.  The sum of the Closing Cash Payment, the Closing Stock Consideration (as adjusted pursuant to Section 5.02), the Assumed Liabilities and the Contingent Payments, to the extent earned, shall be referred to herein as the "Purchase Price."

(d)           Short Term Loan. The Parties acknowledge and agree that, notwithstanding the portion of the Purchase Price actually paid at each Closing, the amount of the sum of the Purchase Price paid by Buyers with respect to the Purchased Assets and Business of Sellers shall be allocated between Sellers as follows: Omega - 66.67%; and Bango Refining - 33.33%.  Accordingly, the Parties agree that the amount by which the Closing Cash Payment made plus the portion of the Closing Stock Consideration issued at the Initial Closing exceeds Omega's portion of the Purchase Price, plus the amount of any loans provided by Buyers to Sellers pursuant to Section 9.20 below, shall be deemed a loan made by Buyers jointly and severally to Sellers in the principal amount of such sum (the sum of all such amounts is referred to as the "Loan Amount"), which original Loan Amount shall be reflected on the Closing Statement delivered by the Parties at the Initial Closing.  The Loan Amount shall be evidenced by a promissory note in substantially the form attached hereto as Exhibit A (the "Seller Note") which shall not bear interest for the six month period following the Initial Closing and shall be paid in full in connection with the Second Closing as part of the transactions occurring at such Closing.  In the event the Second Closing does not occur within six months of the Initial Closing, then the Loan Amount shall bear interest thereafter at a rate equal to 9.5% per annum, which interest shall thereafter be payable by Sellers to Buyers on a monthly basis commencing on the seven month anniversary of the Initial Closing Date and continuing on the same day of each subsequent month until the Second Closing.  Such interest payments shall be paid by wire transfer in immediately available funds to the account designated by Buyers. To secure Sellers' prompt payment and performance of the Secured Obligations (as defined below), Bango Refining, effective as of the Effective Time of the Initial Closing, pledges, assigns and grants to Vertex, a security interest in all of Bango Refining's right, title and interest in, to and under all of the assets of Bango Refining, regardless of where located (all of which will be collectively referred to as the "Collateral"), including:  (i) all accounts and accounts receivable; (ii) all chattel paper; (iii) all documents; (iv) all equipment; (v) all buildings, fixtures and other leasehold improvements; (vi) all general intangibles; (vii) all goods; (viii) all instruments; (ix) all inventory; (x) all commercial tort claims; and (xi) all accessions to, substitutions for and

24

replacements, proceeds, insurance proceeds and products of the foregoing, together with all books and records, customer lists, credit files, computer files, programs, printouts and other computer materials and records related thereto and any general intangibles at any time evidencing or relating to any of the foregoing; to secure the prompt and complete payment and performance of all of Sellers' indebtedness, obligations and liabilities owed to Buyers hereunder whether absolute or contingent and whether now existing or hereafter incurred under this Agreement (collectively, the "Secured Obligations").  Bango Refining hereby authorizes Vertex, or its representatives, to file a UCC financing statement with the Delaware Secretary of State and/or a fixture filing with the local county in Nevada where Bango Refining operates (or such other applicable jurisdictions) as necessary to perfect its security interest granted herein. The foregoing security interest in such assets shall terminate and the Loan Amount shall automatically be satisfied as of the Effective Time of the Second Closing (provided Sellers have repaid the interim funding disclosed in Section 5.01(e) below) and thereupon no Buyer shall have any security interest in or Encumbrance on any consideration paid to Sellers hereunder as of and after such Second Closing.

(e)           Interim Funding Line of Credit. At the Initial Closing, Buyers shall provide Sellers with a short term line of credit loan in the principal amount of up to a maximum amount of $1,600,000 (the "Interim Line"), which loan amounts shall be reasonably requested from time to time by Sellers from Buyers between the Initial Closing and the Second Closing.  The Interim Line shall be evidenced by a promissory note in substantially the form attached hereto as Exhibit B (the "Interim Funding Note") which shall bear interest at a rate equal to 9.5% per annum, which interest shall be payable by Sellers to Buyers on a monthly basis commencing on the six month anniversary of the Initial Closing Date and continuing on the same day of each subsequent month until fully repaid.  The amount of the Interim Line shall be paid down to a maximum outstanding balance (principal and accrued interest) of $600,000 on the Second Closing Date and shall be repaid in full (principal and accrued interest) on or before March 31, 2015.  The Interim Line shall be secured by the Collateral and shall be repaid, at Sellers' election, in either cash or by the surrender, or reduction in the issued number, of shares of Vertex Common Stock (with such shares being valued at the VWAP). In the event the Interim Line is not repaid in full (principal and accrued interest) on or before the Second Closing Date, then 250,000 shares of the 500,000 shares of Vertex Common Stock issuable at the Second Closing shall be retained and held back by Buyers and Vertex to secure the repayment of the remaining amount of the Interim Line then due and will only be issued or released to Sellers upon repayment in full (principal and accrued interest) of such loan amount.

5.02          Adjustments to Closing Consideration.

(a)           Inventory.

(i)           As of the Effective Time of the Initial Closing, Omega shall deliver to Louisiana Buyer at least 3,350,000 gallons of used motor oil and, as of the Effective Time of the Second Closing, Bango Refining shall deliver to Bango Buyer at least 960,000 gallons of used motor oil (in each case, as applicable the "Inventory Target"). For purposes of determining whether the applicable Inventory Target is met only on spec used motor oil shall be counted.

25

(ii)           Additionally, as of the Effective Time of the applicable Closing, the applicable Seller shall deliver to the applicable Buyer such level of chemicals used in the applicable portion of the Business to process used motor oil as is customary and consistent with past practices for such portion of the Business being transferred at such Closing, which value of such chemicals shall be determined and calculated in accordance with GAAP consistently applied by Sellers prior to the Closing.

(iii)           For the purpose of calculating the minimum level of used motor oil Inventory as provided by Section 5.02(a)(i) above, Buyers and Sellers shall jointly conduct separate physical inventories as of an agreed upon date and time (within 5 calendar days of each Closing) of the applicable Seller's used motor oil Inventory which shall be valued and determined as provided in Section 5.02(a)(i), and the Parties' determination of the Inventory Target. Representatives of Buyers and Sellers and their respective accountants and other representatives shall be entitled to observe such physical inventories (and each Party shall have reasonable advance written notice thereof) and Buyers shall have reasonable access to the books and records of Sellers and the applicable portion of the Business upon reasonable advance written request and to request copies of supporting documents for the purpose of verifying the amounts set forth therein.

(iv)           Sellers and Buyers shall in good faith jointly determine and calculate an estimate of the used motor oil Inventory of such Seller as of each Effective Time of a Closing at such time in advance of the applicable Closing as the Parties shall mutually agree.  In the event that such estimate results in a value of such Inventory being less than the applicable Inventory Target, then the Parties, at Sellers' election, shall either reduce the portion of the cash consideration or the Closing Stock Consideration paid at such Closing by the amount of such deficiency, and, at Sellers' additional election, Sellers shall be entitled to pay the amount of such reduction, but not in excess of $750,000 in the aggregate for both Closings (with such excess amount being paid in cash), within ninety (90) calendar days after the applicable Closing Date (the "Deferred Inventory Payment") in which case no adjustment of the cash consideration or Closing Stock Consideration shall be made as a result of such deficiency.  Such Deferred Inventory Payment shall bear interest at a rate of 9.5% per annum until paid and Sellers shall pledge to Buyers that number of shares of the Closing Stock Consideration equal in value to such Deferred Inventory Payment (with such value being determined based upon the Share Reference Price) to secure repayment.  If applicable, the value of the Closing Stock Consideration for such inventory adjustment purposes shall be equal to the Share Reference Price (with such number of shares actually being issued rounded to the nearest whole number). The reduction in the consideration paid hereunder shall be allocated to the applicable Seller recipient as determined by Sellers and without adjustment (except as provided in Section 5.02(c) below) to the number of shares of Vertex Common Stock being placed in the Escrow Account at the Second Closing. Within ninety (90) days after the applicable Closing, Buyers and Sellers shall confirm the actual value of the used motor oil Inventory of the applicable Seller as of the applicable Effective Time and determine whether any adjustments to the estimated value of such Inventory are required based upon actual information on the value of such Inventory as of the applicable Effective Time.  In accordance with Section 5.02(c) below, the Parties shall in good faith apply any such post-Closing adjustments to such Inventory value in determining the amount of the cash consideration or the number of shares of Vertex Common Stock, as applicable, that should have been delivered to Sellers as the applicable portion of the consideration due at such Closing and

26

the Parties shall cooperate in good faith in making such adjustments to the number of shares paid or issued to Sellers.

(v)             The applicable Buyer shall pay the applicable Seller for any used motor oil inventory on hand as of the applicable Closing in excess of the applicable Inventory Target, with the purchase price for such inventory to be paid by the applicable Buyer to the applicable Seller being equal to 88% of the "U.S. Gulf Coast Waterborne No. 6 3%  Sulfur" daily PLATTS posting. If the amount of the used motor oil inventory hereunder is less than the applicable Inventory Target, then the applicable Seller shall be charged for such deficiency at an amount equal to the number of deficient gallons multiplied by 88% of the "U.S. Gulf Coast Waterborne No. 6 3%  Sulfur" daily PLATTS posting.

(b)           Prepaid Assets. As of the Effective Time of the applicable Closing, the applicable Seller shall deliver to the applicable Buyer such level of prepaid assets determined in accordance with GAAP as is customary and consistent with past practices as of the date of Closing for such portion of the Business being transferred at such Closing, which value of the prepaid assets shall be determined and calculated in accordance with GAAP consistently applied by Sellers prior to the Closing.

(c)           Post-Closing Adjustment to the Closing Consideration.  The Parties shall in good faith determine and apply any such post-Closing adjustments to the actual value of such acquired used motor oil Inventory at each Closing and shall apply such adjustments in determining the actual amount of cash consideration or number of shares of Vertex Common Stock, as applicable, that should have been delivered to Sellers as the applicable portion of the amount of the consideration payable to Sellers at the applicable Closing (taking into account for this purpose any adjustment to the consideration paid at such Closing in connection with the determination of the estimated amount of the used motor oil Inventory as provided in Section 5.02(a)(iv) above).  In the event Sellers received too much cash or too many shares of Vertex Common Stock, then Sellers shall cooperate in either repaying such excess cash or adjusting the number of shares of Vertex Common Stock issued at the Second Closing (in the case of an adjustment occurring as part of the Initial Closing) or placed in the Escrow Account (in the case of an adjustment occurring as part of the Second Closing), including cooperating in all reasonable respects in providing such required notices and other information to the Escrow Agent and the Vertex transfer agent to adjust the number of shares of Vertex Common Stock issued to Sellers or the Escrow Account, as applicable.  In the event Sellers are entitled to an additional cash payment or additional shares of Vertex Common Stock, with such choice being at Sellers' election, as a result of the adjustment provided herein, then Buyers shall pay by wire transfer of immediately available funds to the account(s) designated by Sellers such additional cash payment or shall cause Vertex to deliver additional stock certificates representing the additional shares of Vertex Common Stock to be issued to each Seller designee, which such additional number of shares of Vertex Common Stock being allocated to the recipients as designated by Sellers, and which additional shares of the Vertex Common Stock shall bear the legends and restrictions set forth in Section 9.18(c) below. Any such adjusted number of shares of Vertex Common Stock held by each Seller as a result of this post-Closing adjustment procedure shall be rounded to the nearest whole number.  Additionally, to the extent Sellers elected at the applicable Closing to defer payment of a reduction in the portion of the Purchase Price paid at such Closing by obtaining a loan from Buyers as provided in Section 5.02(a)(iv),

27

then Sellers shall repay such loan amount (taking into account the final adjustment to the portion of the Purchase Price to be paid in connection with such Closing as provided in this Section 5.02(c)) in full with accrued interest at the rate specified in Section 5.02(a)(iv). Upon repayment of such deferred payment or loan amount, then the pledge of the shares of Vertex Common Stock contemplated by Section 5.02(a)(iv) shall automatically terminate.

(d)           Disputes.  If Sellers and Buyers cannot agree on the determination of the value of the final used motor oil Inventory for the portion of the Business acquired by the applicable Buyer hereunder at either Closing within one hundred (100) calendar days after the applicable Closing, then either Buyers or Sellers may promptly thereafter cause BDO, LLP or another mutually acceptable third party accounting firm (the "Arbitrating Accountant") to promptly review this Agreement and the disputed items or amounts in determining the value of the final used motor oil Inventory of the applicable portion of the Business acquired by the applicable Buyer at the applicable Closing.  Within thirty (30) calendar days after submission to the Arbitrating Accountant for resolution, Buyers and Sellers shall each indicate in writing their position on each disputed matter and each such Party's determination of the amounts in dispute, with all submissions to the Arbitrating Accountant concurrently copied to the other Parties.  The Arbitrating Accountant shall make a written determination on each disputed matter no later than forty-five (45) calendar days after submission to the Arbitrating Accountant for resolution and such determination will be conclusive and binding upon Buyers and Sellers with respect to that disputed matter.  The proposed final amount of the portion of the Closing Cash Payment or Closing Stock Consideration, as applicable, will be revised as appropriate to reflect the resolution of any such claims pursuant to this Section 5.02(d).  Buyers and Sellers shall cooperate in all reasonable respects, and shall cause their respective representatives to cooperate in all reasonable respects, in good faith with the Arbitrating Accountant and its agents and representatives in connection with any engagement of the Arbitrating Accountant hereunder, including, without limitation, by signing the engagement letter or retainer letter, if any, reasonably requested by the Arbitrating Accountant.  The fees and expenses of the Arbitrating Accountant incurred in the resolution of such dispute shall be shared equally by Buyers and Sellers provided that if the Arbitrating Accountant determines that a Party has adopted a position or positions with respect to the determination of the applicable used motor oil Inventory under this Section 5.02 that is frivolous or clearly without merit, then the Arbitrating Accountant may, in its discretion, assign a greater portion of any such fees and expenses to such Party, with such additional allocation being determined by the Arbitrating Accountant at the time the determination of the Arbitrating Accountant is rendered on the merits.

5.03          Closing Payments.

(a)           Payments to Sellers.

(i)           At the Initial Closing, Buyers shall [a] pay Sellers (or their designee) in connection with the sale and transfer of the Purchased Assets of Omega (allocated among Sellers or such third party designees in accordance with Schedule 5.01 and the funds flow and closing statement shown on the attached Exhibit C (the "Closing Statement")), the aggregate sum equal to the Closing Cash Payment, less any unpaid Transaction Expenses of the Sellers that the Parties have agreed will be paid by Buyers on Sellers' behalf at the Initial Closing and [b]

(b)           Escrow. At the Second Closing, Buyers shall deposit (or shall cause Vertex to deposit) an aggregate amount equal to 1,000,000 shares of Vertex Common Stock, as adjusted under Section 5.02 (the "Escrow Amount"), by the delivery of a stock certificate representing in the aggregate the Escrow Amount, in an account (the "Escrow Account") established with a mutually agreed upon financial institution reasonably approved by the Parties (the "Escrow Agent"), to be administered pursuant to the terms and conditions set forth in an escrow agreement in a form reasonably agreed upon by the parties (the "Escrow Agreement") to be entered into at the Second Closing by the Parties and the Escrow Agent.  The Escrow Agreement shall, among other things, provide that (1) it shall be available to cover all Claims by Buyers for indemnification under this Agreement or any downward adjustment (without duplication) in the Closing Stock Consideration contemplated by Section 5.02 above, (2) 500,000 shares of the Closing Consideration, less the sum of [a] the number of shares surrendered or returned to Buyers (or Vertex) related to any paid indemnification Claims, plus [b] the number of shares covering any then outstanding indemnification Claims (including those which are final and liquidated and those which are not final and liquidated) and plus [c] the number of shares of the Vertex Common Stock used to cover any downward adjustment in the Closing Stock Consideration contemplated by Section 5.02 above, shall be released from the Escrow Account and issued in the name of Sellers (or their Affiliates, as is designated by Sellers to Buyers and as is allowable under applicable Law) on September 15, 2015 and (3) any remaining Escrow Amount (including any interest or dividends thereon), less any amount related to any then outstanding indemnification Claims (including those which are final and liquidated and those which are not final and liquidated), shall be issued in the name of Sellers (or its Affiliates, as is designated by Sellers to Buyers and as is allowable under applicable Law) on the eighteen (18) month anniversary of the Second Closing Date.

(c)           Transaction Expenses.  From and after the Initial Closing, except as provided herein, and in accordance with the contractual obligations related thereto, Sellers or the Equity Owner shall pay or otherwise satisfy all of their obligations in connection with any Transaction Expense. Notwithstanding the foregoing, the Transaction Expenses set forth on the attached Schedule 5.03(c), which consist of retention bonuses due certain employees of the Business, shall be paid to such persons listed on Schedule 5.03(c) and in the aggregate amounts set forth on such Schedule.  One-half of the aggregate bonus amount, less applicable withholding Taxes, shall be paid at the Initial Closing, all of which amount shall be paid by the applicable Seller, to such persons and the remaining one-half, less applicable withholding Taxes, shall be

29

paid on the six-month anniversary of the Initial Closing, all of which amount shall be paid by the applicable Buyer, to such persons provided such employee is still employed with the Business at such time.  Buyers and Sellers, as applicable, shall be entitled to deduct and withhold from any bonuses payable pursuant to this Agreement by Buyers or Sellers, as applicable, to any recipient such amounts as is required by Law for such person to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local, or foreign tax Law.

(d)           Debt.  Set forth on Schedule 5.03(d) (which Schedule shall be updated in connection with the Initial Closing and the Second Closing) is a list identifying each item of Debt of the Business, including the name of the payee and the amount owed to such payee as of the applicable Closing Date, regardless of whether such Seller Debt is to paid off or fully satisfied in connection with such Closing or is assumed by a Buyer and considered an Assumed Liability hereunder (which final payoff amounts, if applicable, shall be reflected on the applicable Closing Statement). Such Schedule shall indicate whether such item of Seller Debt listed therein is an Assumed Liability, an Excluded Liability and/or is being paid off or satisfied in connection with the applicable Closing.  In such event and at Buyers' request, a reasonable time prior to the applicable Closing Date, but in no event less than three (3) Business Days prior thereto, Sellers shall deliver to Buyers payoff letters prepared in good faith and in a form reasonably satisfactory to Buyers from each such holder of Seller Debt showing the payoff amount for the Seller Debt that is to be paid off as of such Closing Date and the payment instructions therefor.  The Parties agree to comply with the foregoing procedures, to the extent applicable, at each Closing to confirm the amounts and status of any Debt of either Seller or which encumbers any Seller's Purchased Assets or portion of the Business then being transferred at such Closing to the applicable Buyer.

5.04          Contingent Consideration. Subject to the provisions of Section 11.08(a), either Buyer may be obligated to make additional payments to either Seller as set forth in this Section 5.04 (each a "Contingent Payment" and collectively, the "Contingent Payments").

(a)           Bango EBITDA Earnout.

(i)           For each Bango Earnout Period, in the event the portion of the Business conducted by Bango Buyer achieves a Bango EBITDA level of at least $3,500,000, then Bango Buyer shall pay to Bango Refining a Contingent Payment equal to the amount set forth in the table set forth below, which amount shall be paid by Bango Buyer to Bango Refining by directing Vertex to issue Bango Refining that number of shares of Vertex Common Stock (rounded to the nearest whole share) equal to the amount of the Contingent Payment earned divided by the VWAP for such shares.  Bango Buyer shall be deemed to have issued such shares to Bango Refining upon delivery of a stock certificate issued to such Seller representing such aggregate number of shares of Vertex Common Stock due hereunder.

Bango EBITDA for period is at least	Contingent Payment
Less than $3,500,000	$0
$3,500,000 but less than $5,000,000	$3,150,000
$5,000,000 or more	$4,500,000

30

(ii)           In the event that the Bango EBITDA for the portion of the Business conducted by Bango Buyer falls between $3,500,000 and $5,000,000, then the amount of the Contingent Payment shall be proportionately adjusted by the same percentage by which the amount of such Bango EBITDA exceeds the minimum threshold of $3,500,000 but is less than the maximum Bango EBITDA threshold of $5,000,000.  By way of example, if the Bango EBITDA for a Bango Earnout Period equals, $4,300,000, then the Contingent Payment that is earned shall equal $3,870,000 (e.g., ($800,000/$1,500,000) * ($4,500,000 - $3,150,000) + $3,150,000).

(iii)           If [a] aggregate Bango EBITDA for the portion of the Business conducted at Bango Buyer during the calendar year 2015 Bango Earnout Period is less than $5,000,000 but the sum of such Bango EBITDA for both Bango Earnout Periods equals or exceeds $10,000,000, then Bango Buyer shall be obligated to pay Bango Refining an additional Contingent Payment equal to the difference between the sum of the Contingent Payments otherwise due for each Bango Earnout Period and $9,000,000.  By way of example, in the event the amount of the Contingent Payment due Bango Refining as calculated above equals $8,000,000 ($3,500,000 for 2015 and $4,500,000 for 2016), but the cumulative amount of the Bango EBITDA for the portion of the Business conducted by Bango Buyer for both Bango Earnout Periods equals $10,500,000, then Bango Buyer shall be obligated to pay Bango Refining an additional Contingent Payment (at the same time the Contingent Payment for the 2016 Bango Earnout Period is due), in shares of Vertex Common Stock based upon the VWAP, equal to $1,000,000 as a result of the application of the provisions of this Section 5.04(a)(iii).

(iv)           Notwithstanding anything herein to the contrary, Buyers shall be entitled to reduce or offset any Contingent Payment earned by Bango Refining hereunder (through a reduction in the number of shares of Vertex Common Stock to be issued, rounded to the nearest whole number) by the cumulative total of the Required Annual Capital Expenditures, for the period commencing with the Second Closing and ending with December 31, 2016 (the "Testing Period"), incurred at the Business' Bango refining facility in Fallon, Nevada in excess of $350,000 per calendar year, excluding for purposes of this calculation up to $1,250,000 of capital expenditures incurred by the applicable Buyer to fund the purchase of a fuel stripper and a scrubber for such facility.  In furtherance of the foregoing, Buyers covenant and agree to, after the Initial Closing and prior to the end of the Bango Earnout Period, fund up to $1,250,000 to purchase a fuel stripper and scrubber at the Bango Buyer's Fallon, Nevada facility. Notwithstanding the foregoing, in the event the cumulative Bango EBITDA during the Testing Period is in excess of $10,000,000 the amount of such excess shall be offset against the amount of the Required Annual Capital Expenditures, thus reducing the amount of such Required Annual Capital Expenditures which Buyers are entitled to offset against any Contingent Payment due Bango Refining hereunder.

(v)           Notwithstanding anything herein to the contrary, the maximum aggregate amount of Contingent Payments that Bango Buyer shall be obligated to pay Bango Refining hereunder with respect to all Bango Earnout Periods shall not exceed $9,000,000 in the aggregate or more than $4,500,000 with respect to any single Bango Earnout Period.

(b)           Omega EBITDA Earnout.

31

(i)           In the event the portion of the Business conducted by Louisiana Buyer achieves an Omega EBITDA level of at least $8,000,000 during any consecutive twelve (12) month period during the Omega Earnout Period, then Louisiana Buyer shall cause Vertex to issue to Omega the number of shares of Vertex Common Stock set forth in the table below, which amount shall be deemed to be delivered upon delivery of a stock certificate to such recipient representing such number of shares of Vertex Common Stock.

Omega EBITDA for period is at least	Contingent Payment (Number of Shares of Vertex Common Stock)
Less than $8,000,000	0
$8,000,000 but less than $9,000,000	470,498
$9,000,000 or more	940,995

(ii)           In the event that the Omega EBITDA for the portion of the Business conducted by Louisiana Buyer falls between $8,000,000 and $9,000,000, then the number of shares of Vertex Common stock to be issued as the Contingent Payment shall be proportionately adjusted by the same percentage by which the amount of such Omega EBITDA exceeds the minimum threshold of $8,000,000 but is less than the maximum Omega EBITDA threshold of $9,000,000.  By way of example, if the Omega EBITDA equals, $8,500,000, then the number of shares of Vertex Common stock to be issued as the Contingent Payment shall equal 705,746 (e.g., the Omega EBITDA is at the mid-point between the minimum threshold of $8,000,000 and the maximum threshold of $9,000,000 so therefore the number of shares to be issued would be at the mid-point between the maximum number of shares issuable and the minimum number of shares that may be issued if any portion of this Contingent Payment is earned).

(iii)           Notwithstanding the foregoing, Louisiana Buyer shall be entitled to reduce or offset any Contingent Payment earned by Omega hereunder (through a reduction in the number of shares of Vertex Common Stock to be issued, rounded to the nearest whole number) by the cumulative total of the Required Annual Capital Expenditures during the Omega Earnout Period incurred at Omega's refining facility in Marrero, Louisiana in excess of $700,000 per calendar year (pro-rated for partial calendar years).  Notwithstanding the foregoing, in the event cumulative Omega EBITDA during the Omega Earnout Period is in excess of $13,500,000 the amount of such excess shall be offset against the amount of the Required Annual Capital Expenditures, thus reducing the amount of such Required Annual Capital Expenditures which Louisiana Buyer is entitled to offset against any Contingent Payment due Omega hereunder.

(c)           Contingent Payment Statements.  At such time as the financial results for the portion of the Business conducted by Bango Buyer are finalized and released, but in no event later than the June 30th following the end of a Bango Earnout Period (i.e., by June 30, 2016 and June 30, 2017) and within a reasonable period of time after the end of the Omega Earnout Period (or earlier if the maximum Omega EBITDA of $9 million has been achieved before then) at which time the financial results for the portion of the Business conducted by Louisiana Buyer are finalized and released with respect to the Business conducted by Louisiana Buyer, Buyers shall furnish to Sellers a written statement (each a "Contingent Payment Statement") accounting for, and describing in reasonable detail, the Bango EBITDA during the applicable Bango Earnout

32

Period and the Omega EBITDA during the Omega Earnout Period (and showing such Omega EBITDA on a monthly basis), and setting forth the amount, if any, of the Bango EBITDA or Omega EBITDA, as applicable, during such period and any Contingent Payment due hereunder with respect to that Bango Earnout Period or the Omega Earnout Period.

(d)           Review Procedure.  Sellers and their representatives shall have the right to review the books and records of the applicable portion of the Business at their expense, under customary and reasonable confidentiality obligations (to be given by Sellers and their representatives in favor of Buyers) for the sole purpose of determining whether a Contingent Payment is due under the terms of this Agreement, and Buyers will provide reasonable access, for a reasonable period of time, during normal business hours for the purpose of such review.  Such review may be initiated only during the thirty (30) day period immediately following receipt by Sellers of the Contingent Payment Statement.  Sellers shall complete such review within thirty (30) days of receipt of or access to the requested books and records.  Such review shall be conducted upon reasonable advance notice and in a manner which will not unreasonably interfere with the conduct of the Business.  Buyers shall make available to Sellers and their representatives as reasonably necessary after receipt of Sellers' request for review, their employees and officers with respect to the Business, and provide access to the books and records of the applicable portion of the Business (including work papers, schedules, memoranda and other documents), and all other information reasonably necessary to make a determination of whether a Contingent Payment is due hereunder.  If, following the conclusion of such review by Sellers or their representatives, Sellers dispute the Contingent Payment Statement, Sellers may, at any point during the thirty (30) day review period, deliver a notice (a "Protest Notice") to Buyers setting forth any such disagreement, which notice shall specify in reasonable detail the nature and dollar amount of any disagreement so asserted, and shall be delivered only if (and to the extent that) Sellers reasonably and in good faith conclude that Buyers' determination as to whether a Contingent Payment is due hereunder, or the calculation of the amount of such Contingent Payment has not been determined in accordance with the guidelines and procedures set forth in this Agreement, or otherwise contains a manifest error.  Buyers and Sellers will use commercially reasonable efforts to resolve any disagreements as to the calculation of the Bango EBITDA or Omega EBITDA and whether and in what amount a Contingent Payment is due hereunder, but if they do not obtain a final resolution within twenty (20) days after Buyers' receipt of the Protest Notice, Buyers and Sellers may seek such available remedies pursuant to the terms of this Agreement.  If Sellers do not deliver the Protest Notice during such 30-day period, then they shall be deemed to have accepted the Contingent Payment Statement.

(e)           Payment.  In the event that a Contingent Payment is due hereunder, Buyers shall cause Vertex to pay the amount of such Contingent Payment by issuing the applicable number of shares of Vertex Common Stock (rounded to the nearest whole share) to Bango Refining or Omega (or their Affiliate), as applicable by the giving of an irrevocable instruction to the transfer agent of Vertex to issue to such Seller (or its authorized designee) a stock certificate(s) representing in the aggregate the number of shares of Vertex Common Stock due hereunder within five (5) Business Days after (i) the final determination of the VWAP with respect to the Bango Earnout which shall be calculated after the earlier to occur of [a] conclusive determination of the amount of the Contingent Payment in accordance with the terms and conditions of this Agreement or [b] deemed acceptance of the amount of the Contingent Payment

33

due to the failure to deliver a Protest Notice or (ii) the final determination of whether the Omega Earnout was earned as provided hereunder.

(f)           Cap on Shares of Vertex Common Stock.  Notwithstanding anything herein to the contrary, the maximum number of shares of Vertex Common Stock to be issued in connection with the Transaction or otherwise hereunder shall not (i) exceed 19.9% of the outstanding shares of Vertex Common Stock immediately prior to the date this Agreement is entered into among the Parties, (ii) exceed 19.9% of the combined voting power of the then outstanding voting securities of Vertex immediately prior to the date this Agreement is entered into among the Parties, in each of subsections (i) and (ii) before the issuance of the Vertex Common Stock hereunder as part of the Transaction, or (iii) otherwise exceed such number of shares of Vertex Common Stock that would violate applicable listing rules of the NASDAQ Stock Market in the event the Vertex stockholders do not approve the issuance of the Vertex Common Stock hereunder as part of the Transaction (the "Share Cap").  In the event the number of shares of Vertex Common Stock to be issued to Sellers hereunder in connection with the Transaction, whether as part of the Contingent Payments or otherwise, exceeds the Share Cap, then Vertex shall instead pay any such additional consideration due Sellers hereunder in cash or, if required, it shall otherwise first obtain the approval of the Vertex stockholders under applicable rules and requirements of the NASDAQ Capital Market prior to issuing such shares of Vertex Common Stock to Sellers.

(g)           Operation of the Business During the Earnout Periods. Buyers shall operate the applicable portion of the Business acquired hereunder through such Buyer as a separate subsidiary entity through the end of the Bango Earnout Period, with respect to the portion of the Business being acquired by Bango Buyer, and through the earlier of satisfaction of the criteria for payment of the Contingent Payment with respect to Omega or the end of the Omega Earnout Period, with respect to the portion of the Business being acquired by Louisiana Buyer, and each such Buyer shall maintain separate accounting books and records during such period. During the foregoing periods, as applicable, the applicable Buyer agrees (i) to operate its portion of the Business in a manner not intentionally designed to reduce or eliminate the amount of the Contingent Payments, but with due regard for practical business considerations, including with respect to profitability criteria, (ii) to provide products and services to customers and clients of the Business on terms, provisions, pricing, timeliness and quality of service comparable to that provided to the applicable Vertex customers generally, and (iii) to not divert sales generation efforts with clients and customers of the applicable portion of the Business away from such portion of the Business and its sales channels with the sole intent of reducing or eliminating the Contingent Payments. Sellers and the Equity Owner agree that the restrictions stated in this paragraph are limited by the reasonable business considerations of Buyers with respect to the operation of the applicable portion of the Business and the ownership and use of the applicable portion of the Purchased Assets. Except for Buyer's required capital expenditures contemplated in Section 5.04 and for regular maintenance capital expenditures arising in the ordinary course of business, nothing herein shall constitute an obligation on the part of the Buyers to acquire any additional equipment or make any predetermined level of capital expenditures during the applicable earnout period.

5.05           Allocation.  The Parties shall allocate the consideration paid hereunder (including the Assumed Liabilities to the extent required by applicable Law) among the Purchased Assets

34

using the methodology set forth on Schedule 5.05 attached hereto.  Unless otherwise required by applicable Law, Buyers and Sellers agree to utilize such values for all Tax purposes, including for purposes of filing IRS Form 8594 and all other Tax Returns filed by each of them. None of the Parties will voluntarily take any position inconsistent therewith upon examination of any such Tax Return, in any Proceeding or otherwise with respect to such Tax Returns. The Parties each agree to provide the other promptly with any other information required to complete Form 8594.  Any Contingent Payment made by a Buyer to the applicable Seller hereunder shall be allocated by such Seller and Buyer to goodwill.

5.06           Adjustments to Prevent Dilution.  Notwithstanding anything to the contrary in this Agreement, if, after the date hereof, and prior to the Second Closing Date, the issued and outstanding Vertex Common Stock: (i) shall have been changed into a different number of shares or a different class by reason of any stock split, reverse stock split, stock dividend, reclassification, recapitalization, split-up, combination, exchange of shares or other similar transaction, including by way of example and not limitation any distribution of cash or property or any redemption of outstanding shares of Vertex Common Stock, then the Closing Stock Consideration, and the Contingent Consideration, and any other similarly dependent items, as the case may be, shall be equitably adjusted to provide to Sellers the same economic effect as contemplated by this Agreement prior to such action, and as so adjusted shall, from and after the date of such event, be the Closing Stock Consideration, the Contingent Consideration or other dependent item, as applicable, subject to further adjustment for any subsequent such event in accordance with this Section 5.06.

This Agreement and each Ancillary Agreement to which any Seller or the Equity Owner is a party has been duly and validly executed and delivered by such Person and, assuming the due authorization, execution and delivery by the other Parties thereto, constitutes the legal, valid and

42

binding obligation of such Person enforceable against such Person in accordance with its terms, except that such enforceability may be limited by bankruptcy, insolvency, reorganization, receivership, moratorium, and other similar laws affecting the rights and remedies of creditors generally and by general principles of equity (including the availability of specific performance or injunctive relief and the application of concepts of materiality, reasonableness, good faith and fair dealing) (the "Bankruptcy and Equity Exception").

(b)           All of the Intellectual Property licensed to any Seller or the Business by a third party (excluding any license implied by the sale of a product and any generally commercially available, off-the-shelf software programs pursuant to which a Seller is obligated to pay license or other fees not exceeding $20,000 per year) and/or licensed by any Seller or the Business to any third party is set forth on Schedule 7.17(b).

(c)           Each Seller owns, is properly licensed under, or otherwise possesses the valid and enforceable right to use all Intellectual Property owned or used by Sellers or the  Business.  Except as set forth on Schedule 7.17(c), there are no Claims or Proceedings pending challenging or, to Sellers' Knowledge, threatening to challenge any Seller's right, title, and interest with respect to its continued use and its right to preclude others from using any such Intellectual Property.  No such Intellectual Property right of Sellers or the Business is or has been judicially determined to be invalid or unenforceable.  No judicial, regulatory, or administrative proceeding is currently pending or, to Sellers' Knowledge, threatened which challenges the validity or enforceability of any such Intellectual Property rights.

(d)           Sellers are not, nor will any of them be as a result of the execution and delivery of this Agreement or the performance of their obligations hereunder, in violation of any licenses, sublicenses or other agreements as to which they are a party or pursuant to which they are authorized to use any third-party Intellectual Property rights.  To Sellers' Knowledge, no third party is infringing upon, misappropriating, or otherwise violating any Intellectual Property of any Seller or the Business, nor has any third party infringed upon, misappropriated, or otherwise violated any Intellectual Property right of any Seller or the Business in the past.  No Seller has infringed upon, misappropriated, or otherwise violated any third-party Intellectual Property rights and, to Sellers' Knowledge, there exists no reasonable basis for any claim of such infringement, misappropriation, or other violation of any third-party Intellectual Property rights.  Sellers have not received from any third party any notice that any of them have infringed upon, misappropriated, or otherwise violated any third-party Intellectual Property rights.

7.18           Accounts Receivable.  All Receivables reflected on the Interim Balance Sheet represent, and those existing as of the applicable Closing Date will represent, valid claims for bona fide, arm's length sales of goods and services actually made by the applicable Seller in the Ordinary Course of Business.  Schedule 7.18 sets forth an aging schedule of the Receivables as of the Interim Balance Sheet Date, and such schedule is correct and complete.

7.19           Insurance.  Schedule 7.19 sets forth a complete and accurate list and description of all policies of insurance presently in effect with respect to any Seller, the Business and the assets of any Sellers, or of which any Seller is the owner, or beneficiary, or under which any Seller or the Business is an insured or loss payee.  True and correct copies of such policies of insurance have been delivered to Buyers.  Other than with respect to the Bango Claim, Schedule 7.19 includes the carrier, the description of coverage, the limits of coverage, retention or deductible amounts, amounts of annual premiums, date of expiration and date through which

56

premiums have been paid with respect to each such policy, and any pending claims in excess of $50,000 and any single claim or set of related claims in excess of $100,000 made against such policies in the last two (2) years.  All such policies are valid, binding, outstanding and enforceable policies.  No notice of cancellation or termination has been received by any Seller or its Affiliates with respect to any such policy, and no act or omission has occurred which could reasonably be expected to result in cancellation of any such policy prior to its scheduled expiration date.  No Seller has been refused any insurance with respect to any material aspect of the operations of the Business nor has its coverage been materially limited by any insurance carrier to which it has applied for insurance.  Sellers have not received any notice from any insurance carrier issuing any such policy that insurance rates therefore will hereafter be materially increased or that there will hereafter be a cancellation or a material increase in a deductible or a nonrenewal of any such policy.  Such policies of insurance are sufficient in all material respects for compliance by Sellers with all applicable requirements of Law and with the applicable requirements of all Material Contracts to which they are a party.

7.21           Customers and Suppliers.  Schedule 7.21 sets forth an accurate and complete list of the ten largest customers of the Business for each of the fiscal years ended December 31, 2012 and December 31, 2013 (determined on the basis of the total dollar amount of net revenues) showing the dollar amount of net revenues from each such customer during each such period.  Schedule 7.21 also sets forth a list of the ten largest suppliers of the Business in terms of dollar volume of purchases during such complete fiscal years.  No customer described on Schedule 7.21 has provided notice that it will not continue to be a customer after the applicable Closing at substantially the same level of purchases and on substantially the same terms made during the periods noted above in this Section and no Seller has any Knowledge of any facts reasonably likely to result in such a change in the level or terms of purchases with any such customer save and except to the extent of any customer whose Contract with a Seller expires by its terms.  No supplier described in Schedule 7.21 has provided notice that it will not continue to be a supplier to the applicable Seller after the applicable Closing with substantially the same quantity and quality of goods and services and substantially the same pricing levels as was provided during the periods noted above in this Section and no Seller has Knowledge of any facts reasonably

57

likely to result in such a change in the quantity and quality of such goods and services or the pricing levels for such goods and services with any such supplier save and except with respect to any supplier whose contract with a Seller expires by its terms.  To Sellers' Knowledge, no customer of the Business has any right to set off any outstanding claims or amounts against any current or future receivables or fees for products or services.

7.22           Brokerage and Finders Fees.  Except as disclosed on Schedule 7.22, no broker, finder or investment banker is entitled to any brokerage, finder's or other fee or commission in connection with this Agreement or the transactions contemplated hereby based upon any agreements, written, oral or otherwise made by or on behalf of the Equity Owner or any Seller.

(b)           Sellers are not a party to any pending Claims or Proceedings and, to the Sellers' Knowledge, there is not any threatened Claims relating to alleged defects in the products sold or services provided by Sellers or the failure of any such products or services to meet the warranty specifications applicable thereto, other than Claims arising in the Ordinary Course of Business consistent with the past experience as reflected on Schedule 7.23.  During the past three years there have been no product recalls, market withdrawals, embargoes, off sale orders, warning letters or seizures with respect to any products sold by the Sellers.

(c)           Each product sold by the Sellers has been distributed and sold in conformity with all applicable Laws and Contractual commitments and all express and implied warranties of Sellers, and to Sellers' Knowledge, Sellers do not have any material Liability (and to Sellers' Knowledge, no event has occurred and no circumstances exist that with notice or lapse of time or both would be reasonably likely to have a Seller Material Adverse Effect) for any replacement, recall, relabeling or other corrective measures in respect thereof or other Losses in connection therewith, other than Claims arising in the Ordinary Course of Business consistent with past experience as reflected on Schedule 7.23.

(d)           To Sellers' Knowledge and other than with respect to the Bango Claim, no Seller has any material Liability (and, to the Sellers' Knowledge, no event has occurred and no circumstances exist that with notice or lapse of time or both would be reasonably likely to result in any material Liability) arising out of any injury to individuals or property as a result of the ownership, possession or use of any product sold by the Sellers.

7.26           Investment Purpose; Accredited Investor Status.  Each Seller (and indirectly its equity owners) is acquiring the Vertex Common Stock for its own account, for investment purposes only and not with a view to, or for sale in connection with, a distribution (other than to the ultimate beneficial owners of the Equity Owner), as that term is used in Section 2(11) of the Securities Act, in a manner which would require registration under the Securities Act or any state securities Laws.  Each Seller can bear the economic risk of its investment in the Vertex Common Stock, has knowledge and experience in financial business matters, is capable of bearing and managing the risk of investment in the Vertex Common Stock and is an "accredited investor" as defined in Regulation D under the Securities Act. Each Seller recognizes that, except as provided in Section 9.18, the Vertex Common Stock has not been registered under the Securities Act, nor under the securities laws of any state and, therefore, cannot be resold unless the resale of the Vertex Common Stock is registered under the Securities Act or unless an exemption from registration is available. Each Seller has carefully considered and has, to the extent it believes such discussion necessary, discussed with its professional, legal, tax and financial advisors, the suitability of an investment in the Vertex Common Stock for its particular tax and financial situation and its advisers, if such advisors were deemed necessary, have determined that the Vertex Common Stock is a suitable investment for it.

7.27           No Other Representations or Warranties. Except for the representations and warranties contained in this Section 7 or in any Ancillary Agreement to which it is a party,

Notwithstanding anything to the contrary in this Section 9.18, in the event that the SEC does not permit Vertex to register all of the shares of Vertex Common Stock issued to the Sellers pursuant to this Agreement, Vertex shall promptly notify the Sellers and thereafter register in the initial registration statement the maximum number of shares on behalf of the Sellers as permitted by the SEC. In the event that the SEC does not permit Vertex to register all of the shares of Vertex Common Stock issued to the Sellers in the initial registration statement, Vertex shall prepare and file subsequent registration statements to register the shares that were not registered in the initial registration statement as promptly as practicable and in a manner permitted by the SEC. Sellers and the Equity Owner shall provide Vertex with such information to be included in the Registration Statement as Buyers may reasonably request.  Buyers shall

(and Buyers shall cause Vertex to) make any and all filings and take any and all other actions that may be necessary, appropriate, or advisable under the applicable state securities laws in furtherance of the offer and sale of the applicable shares of the Vertex Common Stock issued hereunder.  Buyers and Vertex shall furnish, without charge, and on a timely basis, to each holder of the Vertex Common Stock named as a selling shareholder in the Registration Statement such number of copies of the Registration Statement (including the prospectus), each amendment and supplement thereto, and such other documents as such holder may reasonably request in order to facilitate the disposition of the shares of Vertex Common Stock included therein owned by such holder, including any opinion of counsel reasonably requested by Vertex's transfer agent to effect a resale of shares under the Registration Statement, and Buyers hereby consent to the use of each prospectus and such other documents by each such holder in connection with the offering and sale of the shares of the Vertex Common Stock covered by the Registration Statement.  Buyers and Vertex agree to cause the shares of the Vertex Common Stock (whether included in the Registration Statement or not) to be listed on each securities exchange or market where Vertex securities of the same class are listed.

(ii)           Buyers agree to indemnify and reimburse and hold harmless, to the extent permitted by Law, each holder of shares of the Vertex Common Stock named as a selling shareholder in the Registration Statement against all losses, claims, damages, liabilities and expense (including reasonable legal expenses and any expenses incurred in investigating any claims) caused by any untrue or alleged untrue statement of material fact contained in the Registration Statement or prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or any other violation or breach of the Securities Act, the Exchange Act, or any state securities or blue sky laws ("Blue Sky Laws") by Buyers and Vertex or any other Person acting on their behalf, except, as to the holder of shares of the Vertex Common Stock, insofar as the same are caused by or contained in any information furnished in writing to Buyers by such holder of the shares of Vertex Common Stock specifically for use in the preparation of the Registration Statement or by such holder's failure to deliver a copy of the Registration Statement or prospectus after Buyers and Vertex have furnished a sufficient number of copies of the same.

(iii)           In connection with the Registration Statement, Buyers shall use their reasonable best efforts to (and to cause Vertex to):  (i) promptly prepare and file with the SEC any such amendments to the Registration Statement and supplements to the prospectus contained therein as may be necessary to keep the Registration Statement effective for the period of time set forth in Section 9.18(a)(i) above; and (ii) prepare and promptly file with the SEC and promptly notify the selling shareholders named in the Registration Statement of the filing of such amendment or supplement to the Registration Statement or prospectus that is part of the Registration Statement as may be necessary to correct any statements or omissions if, at the time when a prospectus relating to such securities is required to be delivered under the Securities Act, any event shall have occurred as the result of which any such prospectus or any other prospectus as then in effect would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading.

74

(iv)           Buyers and Vertex shall pay all of their own expenses incident to their performance of or compliance with this Section 9.18(a), including all registration and filing fees, printing, messenger, telephone and delivery expenses, fees and disbursements of counsel for them and fees and disbursements of all independent auditors of Vertex.  Each holder of shares of the Vertex Common Stock named as a selling shareholder in the Registration Statement shall pay all of its own expenses, including, but not limited to, fees and disbursements of its counsel and any broker fees and commissions.

(v)           If any registration statement is not declared effective by the SEC (or otherwise does not become effective) on or prior to the Effectiveness Date (any such failure or breach being referred to as an "Event" and the date on which such Event occurs being referred to as the "Event Date"), then in addition to any other rights available to the Sellers, for each thirty (30) day period following the Event Date until the applicable Event is cured, Vertex shall issue to the Sellers a number of additional shares of Vertex Common Stock, as liquidated damages and not as a penalty, equal to 1% of the aggregate number of shares of Vertex Common Stock issued to the Sellers for each thirty (30) day period following the Effectiveness Date that the registration statement has not been declared effective; provided, however, that Vertex shall not be obligated to pay any liquidated damages if Vertex is unable to fulfill its registration obligations as a result of rules, regulations, positions or releases or actions taken by the SEC, and Vertex registers at such time the maximum number of shares of Common Stock as permitted by the SEC.

(vi)           Subject to Section 9.18(b) below which shall take priority over this Section 9.18(a)(vi), all or any portion of the rights under this Agreement shall be automatically assignable (but only with all related obligations) by Seller to any transferee or assignee (as the case may be of all or a portion of such securities if: (i) Seller agrees in writing with such transferee or assignee (as the case may be) to assign all or any portion of such rights, and a copy of such agreement is furnished to Vertex within a reasonable time after such transfer or assignment (as the case may be); (ii) Vertex is, within a reasonable time after such transfer or assignment (as the case may be), furnished with written notice of (a) the name and address of such transferee or assignee (as the case may be), and (b) the securities with respect to which such registration rights are being transferred or assigned (as the case may be); (iii) immediately following such transfer or assignment (as the case may be) the further disposition of such securities by such transferee or assignee (as the case may be) is restricted under the Securities Act or applicable state securities laws if so required; (iv) at or before the time Vertex receives the written notice contemplated by clause (ii) of this sentence such transferee or assignee (as the case may be) agrees in writing with Vertex to be bound by all of the provisions contained herein; (v) such transfer or assignment (as the case may be) shall have been made in accordance with the applicable requirements of this Agreement, if any; (vi) such transfer or assignment (as the case may be) shall have been conducted in accordance with all applicable federal and state securities laws, and Sellers' counsel shall have provided Vertex a legal opinion confirming such compliance with applicable federal and state securities laws; and (vii) such transferee or assignee shall provide Vertex any and all documentation and information reasonably requested to file amendments to the Registration Statement(s) or prospectus supplements in connection therewith to document the transfer or assignment.

(b)           Transfer Restrictions.  Each Seller further acknowledges and agrees that, in order to align each Seller's interest with the interests of the ongoing business of the Buyers and Vertex following the Initial Closing, in addition to the restrictions set forth in Section 9.18(a) above related to compliance with applicable SEC rules, stock exchange requirements or other Laws, for a period of twelve (12) months following the Initial Closing Date, the Closing Stock Consideration (other than with respect to 500,000 shares of the Closing Stock Consideration which are not subject to such twelve month restriction, but are subject to the provisions and limitations of Section 9.18(a) above) may not be sold, pledged, assigned, transferred, conveyed, hypothecated or otherwise transferred or disposed of (which shall include the creation of any Encumbrance on such shares, or transfer of any legal, beneficial or economic interest in such shares, whether or not for value), including any short sale, purchase of publicly traded options with respect to such shares or the entry into hedging or monetization transactions with respect to such shares (the "Transfer Restrictions"). The Transfer Restrictions will expire with respect to each Seller's Closing Stock Consideration in such proportions among Sellers as is determined by Sellers and the Equity Owner.

Additionally, once the Registration Statement is effective, but subject to the Transfer Restrictions, up to 50,000 shares of the Vertex Common Stock issued hereunder may be sold in the aggregate by all Sellers or their Affiliates (with such amount of shares determined in the aggregate for all such persons) each week, if permissible by the rules and guidelines of the SEC, any exchange upon which such shares are listed, the Financial Industry Regulatory Authority, Inc. (FINRA) or any other Governmental Authority.  Additionally, any block trade or sale by Sellers (or their Affiliates) of more than 50,000 shares of Vertex Common Stock each week must be approved in advance in writing by Vertex, which approval shall not be unreasonably withheld, conditioned or delayed.

(c)           Legend. Each Seller acknowledges and agrees that the stock certificates representing the Vertex Common Stock issued hereunder shall contain legends substantially in the form of the following, as well as any additional legends that may be required by applicable Law or as Vertex may reasonably deem necessary or advisable (and a stop transfer order may be placed against the transfer of such shares); provided, however, that only the Vertex Common Stock subject to the Escrow Agreement shall bear the first legend identified below:

THESE SECURITIES ARE SUBJECT TO AN ESCROW AGREEMENT WITH THE ISSUER AND THE ESCROW AGENT NAMED THEREIN (THE "ESCROW AGREEMENT"), A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICES OF THE ISSUER AND WHICH, AMONG OTHER MATTERS, PLACES RESTRICTIONS ON THE DISPOSITION OF THE SECURITIES. THESE SECURITIES WILL BE DEPOSITED WITH THE ESCROW AGENT PURSUANT TO THE ESCROW AGREEMENT AND MAY NOT BE OFFERED, EXCHANGED, TRANSFERRED, SOLD, ASSIGNED, PLEDGED, PARTICIPATED, HYPOTHECATED OR OTHERWISE DISPOSED OF (EACH A "TRANSFER") FOR SO LONG AS THEY ARE SUBJECT TO THE ESCROW AGREEMENT.

THESE SECURITIES ARE SUBJECT TO CERTAIN RESTRICTIONS SET FORTH IN THE ASSET PURCHASE AGREEMENT DATED MARCH 17,

76

2014, BY AND AMONG CERTAIN AFFILIATES OF THE ISSUER AND CERTAIN OTHER PERSONS, WHICH RESTRICT THE RIGHT TO TRANSFER, SELL OR OTHERWISE DISPOSE OF THESE SECURITIES.  A COPY OF SUCH ASSET PURCHASE AGREEMENT IS AVAILABLE FOR REVIEW BY THE RECORD HOLDER OF THESE SECURITIES AT THE PRINCIPAL OFFICES OF THE ISSUER.

THIS SECURITY HAS NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. THIS SECURITY AND THE SECURITIES ISSUABLE UPON CONVERSION OF THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN SECURED BY SUCH SECURITIES.

(d)           Sellers Cooperation with Respect to Financial Matters.  Sellers and the Equity Owner will cooperate with any reasonable requests of Buyers or Vertex in connection with Vertex's compliance with applicable laws regarding the transactions hereunder, including (i) providing access to Sellers' management upon reasonable prior notice during normal business hours to assist with Vertex's SEC reporting obligations of the transactions hereunder, including the preparation by Vertex of pro forma financial information under Regulation S-X, Form 8-K and the other rules and regulations of the SEC, addressing purchase accounting issues and preparation of any SEC waiver letters and (ii) allowing access to Sellers' independent registered public accounting firm and discussing with such accounting firm its audit work on the Sellers' financial statements (including, to the extent required by such firm, consent to the release of their work papers to Buyers or their independent registered public accounting firm), and discussing with and obtaining from Sellers' independent registered public accounting firm consents to fulfill Vertex's reporting requirements, including financial statements and the notes thereto.  Without limiting the foregoing, not later than 30 days after each Closing Date, the Equity Owner shall provide to Buyers such information as Vertex may reasonably require to prepare pro forma financial information regarding the Business required to be filed in an amendment to the Closing Form 8-K in accordance with the requirements of Regulation S-X, Form 8-K and the other applicable rules and regulations of the SEC.  In the event that Buyers, Vertex or their independent registered public accounting firm or the SEC has comments or questions on such information after the applicable Closing, the Equity Owner will (and will cause its independent registered public accounting firm to) assist and cooperate with Vertex to resolve any such comments or questions and take such reasonable actions with respect to such information as are

77

necessary for Vertex to satisfy its obligations under Regulation S-X, Form 8-K and the other applicable rules and regulations of the SEC with respect to the pro forma financial information.

(e)           Removal of Securities Act Legends.  Certificates or other instruments evidencing the shares of Vertex Common Stock issued to Seller pursuant to this Agreement shall not be required to contain the third legend set forth above (the "Securities Act Legend") (i) following the sale of any shares pursuant to the plan of distribution of a registration statement covering the resale of such shares that is effective under the Securities Act, (ii) following any sale of such shares pursuant to Rule 144, (iii) if such shares are eligible to be sold, assigned or transferred under Rule 144 without any limitation or the need to be in compliance with Rule 144(c)(1), (iv) in connection with a sale, assignment or other transfer (other than under Rule 144), provided that Seller provides the Company with an opinion of counsel to Seller, in a generally acceptable form, to the effect that such sale, assignment or transfer of the shares may be made without registration under the applicable requirements of the Securities Act or (v) if such legend is not required under applicable requirements of the Securities Act (including, without limitation, controlling judicial interpretations and pronouncements issued by the SEC). If a legend is not required pursuant to the foregoing, Vertex shall immediately but in no event later than five trading days following the delivery by Seller to Vertex or Vertex's transfer agent (with notice to Vertex) of a legended certificate representing such shares (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer, if applicable), together with any other deliveries from Seller as may be required by Vertex or Vertex's counsel, as directed by Seller, either: (A) provided that the transfer agent is participating in the DTC Fast Automated Securities Transfer Program and such shares are Vertex Common Stock, credit a number of shares of Vertex Common Stock equal to the number of shares of Vertex Common Stock represented by the certificate so delivered by Seller to Seller's or its designee's balance account with DTC through its Deposit/Withdrawal Custodian system or (B) if the transfer agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver (via reputable overnight courier) to Seller a certificate representing such shares that is free from all restrictive and other legends, registered in the name of Seller or its designee (the date by which such credit is so required to be made to the balance account of Sellers or Seller's nominee with DTC or such certificate is required to be delivered to Investor pursuant to the foregoing is referred to herein as the "Required Delivery Date").

(f)           Failure to Timely Deliver; Buy-In. If Vertex fails to properly deliver certificates without the Securities Act Legend or so properly credit the balance account of Sellers or Seller's nominee with DTC by the Required Delivery Date, and if on or after the Required Delivery Date Seller purchases (in an open market transaction or otherwise) shares of Vertex Common Stock to deliver in satisfaction of a sale by Seller of shares of Vertex Common Stock that Seller anticipated receiving from Vertex without any restrictive legend, then, in addition to all other remedies available to such Seller, Vertex shall, within five trading days after the Required Delivery Date, promptly honor its obligation to deliver to Seller a certificate or certificates or credit Seller's DTC account representing such number of shares of Vertex Common Stock that would have been issued if Vertex timely complied with its obligations hereunder and pay cash to Seller in an amount equal to the excess (if any) of the Buy-In Price (as defined below) over the product of (A) such number of shares of Vertex Common Stock that Vertex was required to deliver to Seller by the Required Delivery Date times (B) the closing price of the Vertex Common Stock on the trading day immediately preceding the Required

78

Delivery Date. If within five trading days following the Required Delivery Date, Vertex fails to deliver to Seller a certificate or certificates or credit Seller's DTC account representing such number of shares of Vertex Common Stock that would have been issued if Vertex timely complied with its obligations hereunder, Vertex shall pay cash to Seller in an amount equal to Seller's total purchase price (including brokerage commissions, if any) for the shares of Vertex Common Stock so purchased (the "Buy-In Price"), at which point Vertex's obligation to deliver such certificate or credit Seller's balance account shall terminate and such shares shall be cancelled.

9.19           Vertex Additional Covenants.  Vertex covenants and agrees as to itself and its Subsidiaries (as applicable) that, from and after the date hereof and continuing until the Initial Closing Date, except (x) as otherwise set forth below or as otherwise required by this Agreement, (y) as required by applicable Law or (z) with the prior written consent of the Sellers (which consent shall not be unreasonably withheld, conditioned or delayed):

(b)           neither Vertex nor its Subsidiaries shall (i) amend its Organizational Documents or any of the Organizational Documents of any of its Subsidiaries except for such amendments that would not prevent or materially impair the consummation of the transactions contemplated by this Agreement, (ii) declare, set aside or pay any dividends or make any distributions (whether payable in cash, stock or property) in respect of any capital stock, (iii) split, combine or reclassify its outstanding shares of capital stock without adjusting the Closing Stock Consideration and/or the Contingent Consideration pursuant to Section 5.06, (iv) authorize or issue additional shares or new classes of stock, except for issuances of shares of Vertex Common Stock (or securities convertible into shares of Vertex Common Stock) in connection with grants of equity compensation to its employees, officers, directors and consultants under and in accordance with the terms and conditions of the existing Vertex stock incentive plans or in connection with securing financing to consummate the transactions contemplated hereby, or (v) repurchase, redeem or otherwise acquire any shares of its capital stock or any securities convertible into or exchangeable or exercisable for any shares of its capital stock or permit any of its Subsidiaries to purchase or otherwise acquire, any shares of its capital stock or any securities convertible into or exchangeable or exercisable for any shares of its capital stock, other than as required by currently in effect stock incentive programs;

(c)           neither Vertex nor any of its Subsidiaries shall adopt a plan of liquidation or dissolution;

(d)           Vertex shall not take or cause to be taken any action that would reasonably be expected to materially delay, impair or prevent the consummation of the transactions contemplated hereby; and

79

(e)           neither Vertex nor any of its Subsidiaries will authorize or enter into an agreement to do anything prohibited by the foregoing.

9.20           Capital Expenditures.  Prior to the Second Closing, Vertex and Buyers agree to cooperate in all reasonable respects in assisting Sellers with purchasing a fuel stripper and scrubber for the Bango Facility, including providing Bango Refining with loaned funds to acquire such capital equipment on terms mutually agreed upon and otherwise taking such other reasonable actions to assist Sellers in connection therewith.

9.21           Reports Under the Exchange Act. With a view to making available the benefits of certain rules and regulations of the SEC, including Rule 144, that may at any time permit the Seller to sell Vertex Common Stock to the public without registration or pursuant to a registration on Form S-1 or Form S-3, until the earlier of (i) two years from the date hereof or (ii) such time as the shares of Vertex Common Stock issued to Seller pursuant to this Agreement may be sold without volume restriction pursuant to Rule 144 and without the requirement to be in compliance with Rule 144(c)(1), Vertex agrees to:

(a)           make and keep public information available, as those terms are understood and defined in Rule 144;

(b)           file with the SEC in a timely manner all reports and other documents required of Vertex under the Securities Act and the Exchange Act; and

9.22           Covenants Relating to Finished Goods Inventory.  Subsequent to each of the Initial Closing and the Second Closing, Buyers, as applicable, shall cooperate in all reasonable with Sellers to allow Sellers to sell, market and deliver all Finished Goods Inventory including: (a) with respect to Omega Refining, the sale of vacuum gas oil, asphalt, and condensate pursuant to the terms of existing contracts; (b) with respect to the Bango Facility, allow Sellers to sell, market and deliver base oils consistent with past practices; and (c) to the extent the applicable Buyer receives payment for sales contemplated under subsections (a) and (b), promptly remit such payments to each applicable Seller; provided, however, Buyers' obligations under this Section shall not unreasonably interfere with the operation of the Business by the applicable Buyer.

9.23           Used Motor Oil Buy/Sell Contract. Between the date hereof and the Second Closing, the Parties agree to in good faith cooperate in all reasonable respects in connection with the termination or amendment of that certain second used motor oil buy/sell contract dated as of August 1, 2012 (and any other predecessor or related agreement binding upon the Business)

80

entered into by Sellers and the Equity Owner with Thermo Fluids Inc. (collectively, the "TFI Contract") in order to terminate or modify the noncompetition and other restrictive covenants imposed upon the Business in the TFI Contract. The terms of such amendment, modification or termination shall be subject to Vertex's sole approval and, if approved by Vertex, the TFI Contract, as modified or amended, if applicable, shall be deemed an Assumed Contract hereunder.

10.02           Notice of Termination; Effect of Termination.

(a)           Termination of this Agreement pursuant to Sections 10.01 shall not in any way affect the rights of any Party against any other Party that has violated or breached any of such Party's representations, warranties or covenants of this Agreement prior to termination hereof.  If Vertex or a Buyer is the breaching party, then Vertex and Buyers shall indemnify Sellers and their Affiliates for all Losses arising out of such breach. If a Seller or the Equity Owner is the breaching party, then Sellers and the Equity Owner shall indemnify Buyers and their Affiliates for all Losses arising out of such breach.  Subject to the foregoing, the Parties' payment obligations under Section 9.17(a) shall survive the termination of this Agreement.

(d)           except as set forth herein, including as provided on Schedule 5.03(c) with respect to Buyer's portion of the retention bonuses, any Transaction Expenses incurred or payable by any Seller or the Equity Owner that are payable or paid by either Buyer on or after the Initial Closing, including any brokerage or finders' fees or commissions or similar payments based upon any agreement or understanding alleged to have been made by any Person with any Equity Owner and/or any Seller (or any Person acting on any of their behalf) in connection with the transactions contemplated hereby;

84

facility to its normal state of operations to the extent required to comply with applicable Laws and Permits or to the extent required to bring such facility and its operations into a condition that enables Buyers to operate the facility consistent with Sellers' past practices.

11.03           Procedures.

(a)           Claims Among the Parties. Following the discovery of any facts or conditions which could reasonably be expected to give rise to a Claim for Losses hereunder, the Party seeking indemnification under this Agreement (the "Indemnified Party") shall, within thirty (30) days thereafter, provide written notice (the "Claim Notice") to the Party from whom indemnification is sought (the "Indemnifying Party"), specifying the factual basis of the Claim in reasonable detail to the extent then known by the Indemnified Party; provided, however, that the failure to give such notice in such time period shall not relieve the Indemnifying Party of its obligations hereunder except to the extent the Indemnifying Party is materially adversely affected thereby, and then only to the extent of such material adverse effect.  If such Losses are final and liquidated, the Claim Notice shall so state and such amount shall be deemed the amount of the Claim of the Indemnified Party.  If such Losses are not final and adjudicated, the Claim Notice shall so state and in such event, a Claim shall be deemed asserted against the Indemnifying Party by the Indemnified Party in the amount specified in the Claim Notice.

(b)           Third Party Claims. The following provisions shall apply to any Claim for Losses subject to indemnification under this Agreement that is a Proceeding filed or instituted by, or the making of any Claim or demand by, any third party, including any Governmental Authority (a "Third Party Claim"):

(i)           The Indemnified Party or Parties shall give the Indemnifying Party or Parties prompt written notice of the Third Party Claim (the "Third Party Claim Notice"), specifying the factual basis of the Third Party Claim in reasonable detail to the extent then known by the Indemnified Party.  If such Losses are final and liquidated, the Third Party Claim Notice shall so state and such amount shall be deemed the amount of the Third Party Claim of the Indemnified Party.  If such Losses are not final and adjudicated, the Third Party Claim Notice shall so state and in such event, a Third Party Claim shall be deemed asserted against the Indemnifying Party by the Indemnified Party in the amount specified in the Third Party Claim Notice.  Failure to promptly give the Third Party Claim Notice shall not affect the Indemnifying Party's duties or obligations under this Section 11, to the extent it does not materially adversely affect the Indemnifying Party's ability to defend such Claim, and then only to the extent of such adverse effect.

(ii)           Within 30 days after the Third Party Claim Notice is received from the Indemnified Party, or such shorter period as is required to avoid prejudice in any Claim, suit or Proceeding, the Indemnifying Party shall have the right to assume and thereafter conduct the defense of the Third Party Claim with counsel of its choice reasonably satisfactory to the Indemnified Party.  If the Indemnifying Party has assumed the defense of the Third Party Claim as provided herein, the Indemnifying Party will not be liable for any legal expenses subsequently incurred by the Indemnified Party in connection with the defense of the Third Party Claim; provided, however, that if the Indemnifying Party fails to take reasonable steps necessary to defend diligently such Third Party Claim, the Indemnified Party may assume its own defense,

85

and the Indemnifying Party will be liable for all reasonable costs and expenses actually paid or incurred in connection with such defense.  The Indemnifying Party or the Indemnified Party, as the case may be, has the right to participate in (but not control), at its own expense, the defense of any Third Party Claim which the other is defending as provided herein.  The Indemnifying Party, if it has assumed the defense of any Third Party Claim, must conduct the defense of the Third Party Claim actively and diligently thereafter in order to preserve its rights and may not, without the prior written consent of the Indemnified Party, consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim that (i) does not include as an unconditional term thereof the giving by the claimant or the plaintiff to the Indemnified Party a complete release from all Liability in respect of such Third Party Claim, (ii) grants any injunctive or equitable relief or (iii) may reasonably be expected to have an adverse effect on the business of the Indemnified Party.

(c)           Defense of Claim. Unless and until the Indemnifying Party assumes the defense of the Third Party Claim as provided in Section 11.03(b) above, the Indemnified Party may defend against the Third Party Claim in any manner it deems appropriate, and any reasonable costs or expenses incurred by the Indemnified Party in connection with such defense shall constitute Losses which are the responsibility of the Indemnifying Party.

(d)           Conflicts. Notwithstanding anything to the contrary in this Section 11, if (i) there is a reasonable probability that any Third Party Claim may adversely affect the Indemnified Party other than as a result of money damages or other money payments, (ii) the Third Party Claim seeks an injunction or other equitable relief against the Indemnified Party, or (iii) with respect to Claims for Losses hereunder by a Buyer Indemnified Party, if any Third Party Claim is reasonably likely to [a] result in an amount of Claims for Losses hereunder involving money damages or other money payments in an aggregate amount that exceeds the Escrow Amount then held in the Escrow Account, or [b] is asserted directly or on behalf of a Person that is a supplier or customer of the Business, then the Indemnified Party (and not the Indemnifying Party) shall have the right to undertake and control the defense, compromise and/or settlement of such Third Party Claim so long as it does so actively and in good faith and the Indemnifying Party shall not settle or compromise, or consent to the entry of judgment with respect to, any Third Party Claim without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld, delayed or conditioned).  In such circumstances, if the Indemnified Party undertakes and controls the defense of the Third Party Claim, it shall not compromise or settle, or consent to the entry of a judgment with respect to, the Third Party Claim without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld, delayed or conditioned).

11.04           Payment.  The Indemnifying Party shall promptly pay (or through application of the Indemnified Party's offset right pursuant to Section 11.08, if applicable, or cause the Escrow Agent to pay in connection with a Claim for Losses hereunder by a Buyer Indemnified Party that is to be satisfied from the Escrow Account) the Indemnified Party any amount finally determined to be due under this Section 11.  Upon final judgment, determination, settlement or compromise of any Third Party Claim, the Indemnifying Party shall pay (or through application of the Indemnified Party's offset right pursuant to Section 11.08, if applicable, or cause the Escrow Agent to pay in connection with a Claim for Losses hereunder by a Buyer Indemnified Party that is to be satisfied from the Escrow Account) promptly on behalf of the Indemnified Party, and/or

86

to the Indemnified Party in reimbursement of any amount theretofore required to be paid by it, the amount so determined by final judgment, determination, settlement or compromise and all other Losses of the Indemnified Party with respect thereto, unless, in the case of a judgment, an appeal is made from the judgment, in each case subject to the limitations and conditions contained in this Section 11.

11.05           Limitations on Indemnification.  Except in the case of fraud or an intentional misrepresentation, as to which Claims may be brought without limitation as to time or amount:

(a)           Survival Period. No claim or action shall be brought under Section 11.01(a) or 11.02(a), as the case may be, for breach of or inaccuracy in a representation or warranty after the date which is equal to September 15, 2015 with respect to the representations and warranties provided in connection with the Initial Closing or eighteen (18) months after the Second Closing Date with respect to the representations and warranties provided in connection with the Second Closing.  Notwithstanding the foregoing or any other provision of this Agreement:

(i)           The foregoing time limitations shall not apply to any claim or action brought for breach of or inaccuracy in any representation or warranty made in or pursuant to Section 7.01 (Organization and Qualification), Section 7.02 (Authorization of Agreement; Validity of Agreement; Necessary Action), Section 7.03 (No Conflict; Required Consents and Filings), Section 7.11(a) (Title to Assets), Section 7.22 (Brokerage and Finders Fees), Section 8.01 (Organization, Good Standing and Qualification), Section 8.02 (Capital Structure), Section 8.04 (Corporate or Limited Liability Company Authority) and/or Section 8.13 (Brokers and Finders) (collectively, the "Fundamental Representations"), and Sellers and the Equity Owner, on the one hand, and Vertex and Buyers, on the other hand, hereby waive all applicable statutory limitation periods with respect thereto.

(ii)           A claim or action brought for breach of or inaccuracy in any representation or warranty made in or pursuant to Section 7.13 (Compliance with Environmental Laws) and Section 7.14 (Taxes) (collectively, the "Surviving Representations") may be brought until the date that is 30 days after the expiration of all applicable statutes of limitation under applicable Laws related thereto (including extensions or waivers thereof).

(iii)           Any claim or action made by an Indemnified Party by providing the Indemnifying Party with written notice of an alleged breach of or inaccuracy in a representation or warranty prior to the expiration of the survival period for such claim or action, if any, shall be preserved despite the subsequent expiration of such survival period.

(b)           Basket. Except with respect to claims for breaches of or inaccuracies in the Fundamental Representations or the Surviving Representations (as to which the limitations in this Section 11.05(b) shall not apply), the Indemnified Parties shall not be entitled to indemnification under Section 11.01(a) or 11.02(a), as applicable, for breaches of or inaccuracies in representations and/or warranties unless the aggregate amount of all indemnification obligations under Section 11.01(a) or 11.02(a), as applicable, for breaches of or inaccuracies in representations and/or warranties (but for this Section 11.05(b)) exceeds Four Hundred Thousand and 00/100 Dollars ($400,000.00) (the "Basket"); provided, however, if such aggregate Losses

87

exceed the Basket, indemnification for all Losses incurred shall be fully payable without any deductible.  By way of clarification, for purposes of the limitations to indemnification in this Section 11.05(b), the Indemnifying Party shall collectively mean Sellers and the Equity Owner and their successors and assigns, on the one hand, or Buyers and Vertex and their successors and assigns, on the other hand, and the application of the Basket (and whether it is met) shall be done separately with respect to Sellers and the Equity Owner and their successors and assigns, on the one hand, or Vertex and Buyers and their successors and assigns, on the other hand.

(c)           Cap.  Except with respect to claims for breaches of or inaccuracies in the Fundamental Representations or the Surviving Representations, or any claim pursuant to Section 11.01(b), (c) or (d) or Section 11.02(b), (c), (d), (e) or (f) (as to which the limitations in this Section 11.05(c) shall not apply), the aggregate amount of all Losses paid by an Indemnifying Party under this Section 11 shall not exceed Five Million and 00/100 Dollars ($5,000,000.00) (the "Cap").  Further, the aggregate amount of Losses paid by all Seller Indemnifying Parties under this Section 11 shall not exceed the Purchase Price actually received by Sellers.  By way of clarification, for purposes of the limitations to indemnification in this Section 11.05(c), the Indemnifying Party shall collectively mean Sellers and the Equity Owner (and their successors and assigns), on the one hand, or Vertex and Buyers (and their successors and assigns), on the other hand.

(d)           Collateral Sources.  The amount of any indemnity obligation of any Indemnifying Party to the Indemnified Parties provided in this Agreement shall be computed net of any insurance proceeds actually received by an Indemnified Party (net of any deductible amounts, increases in premiums and costs and expenses incurred with respect to such insurance claims) in connection with or as a result of any Claim giving rise to an indemnification Claim hereunder.  If the indemnity amount is paid to the Indemnified Parties by any Indemnifying Party prior to the Indemnified Party's actual receipt of insurance proceeds related thereto, the Indemnified Party shall, if permissible by the terms of the applicable policy, assign its right to such insurance and allow the Indemnifying Party to pursue collection of such insurance proceeds or, if such payment has been made by any of the Indemnifying Parties, and an Indemnified Party subsequently receives such insurance proceeds, then the Indemnified Party shall promptly pay to or at the direction of the Indemnifying Party the amount of such insurance proceeds subsequently received (net of all related costs, expenses and other Losses), but not more, in the aggregate, than the indemnity amount paid by the Indemnifying Party.  Notwithstanding the foregoing, no Indemnified Party shall be required to (i) pursue such insurance prior to seeking indemnification under this Section 11 or (ii) commence litigation to recover proceeds under such insurance policies if it is unreasonable do so.

(e)           Other Limits. No Indemnified Party shall be entitled to indemnification hereunder for any Loss in respect of any Claim to the extent that (i) such Loss would not have arisen but for the enactment of any legislation not in effect on the date hereof or on the applicable Closing Date or any change of any law or administrative practice of any governmental agency after the applicable Closing Date or any change in any generally accepted accounting principles after the applicable Closing Date, including in each case any legislation or change which takes effect retrospectively, (ii) such Loss has arisen as a result of any act or omission by the Party seeking indemnification on or after the applicable Closing Date (including without limitation resulting from any change in accounting principles, practices or methodologies) and to

88

the extent of any Loss arising from any breach by the Party seeking indemnification of its obligations under this Agreement (provided such party's breach is a principal cause or principal contributing factor to such party's Losses related thereto), and (iii) such Loss is offset by a corresponding gain accruing after the applicable Closing Date, directly or indirectly, to the benefit of the Party seeking indemnification, as a direct result of the act, matter, omission or circumstance giving rise to such Loss.

(f)           Taxes; Third Party Rights. The amount of any Loss incurred by an Indemnified Party shall be reduced by (i) the net amount of the Tax benefits actually realized by the Indemnified Party, or its Affiliates, in the Taxable year of such Loss which is generated by reason of such Loss (and no such Indemnified Party shall be entitled to any indemnification under Section 11.01 or 11.02, as applicable, in relation to any Tax adjustment or assessment that only has a timing effect and results in the mere shifting of Tax over time, including without limitation depreciation and amortization), or (ii) any amount equivalent to any damages, indemnification, restitution or reimbursement or any other amounts, net of Taxes, actually recovered after the applicable Closing Date by the Indemnified Party, or its Affiliates, from a third party (other than any insurer) in relation to the act, matter, omission or circumstance giving rise to the claim for indemnification.

(g)           Exclusivity of Indemnification Provision.  Except for the resolution of disputes related to Section 5.02 or Section 5.06 to be resolved by the Arbitrating Accountant, the indemnity provided for in Section 11 shall be the sole and exclusive remedy of Buyers, and Sellers, and their respective Affiliates and their Indemnified Parties after the applicable Closing for any inaccuracy of any representation or warranty of the other party or any failure or breach of any covenant, obligation, condition or agreement to be performed or fulfilled by the other party, other than claims of, or causes of action arising from common law fraud or willful, wanton or intentional misconduct.  In furtherance of the foregoing, each Party hereto, on its own behalf and on behalf of its Affiliates and its other Indemnified Parties, hereby waives, from and after the applicable Closing, to the fullest extent permitted under applicable law, any and all rights, claims and causes of action, other than claims of, or causes of action arising from common law fraud or willful, wanton or intentional misconduct, such Person may have against the other party or any of its Affiliates or its other Indemnified Parties relating to the subject matter of this Agreement arising under or based upon any Law or otherwise (except in each case pursuant to the indemnification provisions and rights related thereto set forth in this Agreement).

11.06           Materiality.  Solely for purposes of calculating Losses under this Section 11 to determine whether the Basket has been met (and not as to the determination of whether or not there has been a breach), any breach of any representation or warranty shall be determined without regard to any materiality, Seller Material Adverse Effect, Vertex Material Adverse Effect or other similar qualification contained in or otherwise applicable to such representation or warranty.

11.07           Treatment of Indemnification Payments.  Any payment made hereunder in respect of an indemnification obligation shall be treated by the Parties as an adjustment to the Purchase Price to the extent permitted under applicable Law.

11.08           Offset.

89

(a)           By Buyer.  Subject to the procedures set forth in this Section 11.08, the Buyer Indemnified Parties shall be entitled to offset against any payments due to any Seller (including in connection with the post-Closing Purchase Price adjustment procedure set forth in Section 5.02, in connection with any Contingent Payment or in connection with any other amounts due Sellers or their Affiliates hereunder), any amounts due the Buyer Indemnified Parties pursuant to Sellers' obligation under the post-Closing Purchase Price adjustment procedure set forth in Section 5.02 or pursuant to Sellers' and the Equity Owners' obligation to indemnify the Buyer Indemnified Parties under Section 11.02 above and such offset amounts shall be deemed a payment against such obligations and shall not trigger a default under this Agreement.  Buyers shall provide Sellers a written notice of their intent to offset any payments due Sellers specifying in reasonable detail the basis for the offset and Buyers' calculation of the amount of such offset (the "Buyer Offset Notice"), which may be part of a Claim Notice or a Third Party Claim Notice.  If Sellers dispute Buyers' exercise of its offset right, then Sellers shall furnish Buyers an objection notice within 15 days of Sellers' receipt of the Buyer Offset Notice specifying in reasonable detail the basis for any such dispute.  If Sellers do not deliver the dispute notice to Buyers' exercise of its offset right within such 15 day period, then Buyers shall be entitled to offset against any payments due Sellers, the amounts so specified in the Buyer Offset Notice.  Any disputed items stemming from Buyers' submittal of the Buyer Offset Notice shall be resolved in accordance with the procedures set forth in Section 12.06.  No amounts otherwise due and payable to Sellers need be paid after the Buyer Offset Notice is given until such time as the dispute is resolved; provided, however, Buyers shall not be entitled to withhold payment of amounts in excess of the disputed amount.  No default shall be deemed to have occurred after the Buyer Offset Notice is given until the dispute is resolved.

(b)           By Sellers.  Subject to the procedures set forth in this Section 11.08, the Seller Indemnified Parties shall be entitled to offset against any amounts due to Vertex or any Buyer or their Affiliates hereunder, any amounts due the Seller Indemnified Parties pursuant to Vertex's and Buyers' obligation to indemnify the Seller Indemnified Parties under Section 11.01 above and such offset amounts shall be deemed a payment against such obligations and shall not trigger a default under this Agreement.  Sellers shall provide Buyers a written notice of their intent to offset any payments due Vertex or Buyers specifying in reasonable detail the basis for the offset and Sellers' calculation of the amount of such offset (the "Seller Offset Notice"), which may be part of a Claim Notice or a Third Party Claim Notice.  If Buyers dispute Sellers' exercise of its offset right, then Buyers shall furnish Sellers an objection notice within 15 days of Buyers' receipt of the Seller Offset Notice specifying in reasonable detail the basis for any such dispute.  If Buyers do not deliver the dispute notice to Sellers' exercise of its offset right within such 15 day period, then Sellers shall be entitled to offset against any payments due Vertex or Buyers, the amounts so specified in the Buyer Offset Notice.  Any disputed items stemming from Sellers' submittal of the Seller Offset Notice shall be resolved in accordance with the procedures set forth in Section 12.06.  No amounts otherwise due and payable to Buyers need be paid after the Seller Offset Notice is given until such time as the dispute is resolved; provided, however, Sellers shall not be entitled to withhold payment of amounts in excess of the disputed amount.  No default shall be deemed to have occurred after the Seller Offset Notice is given until the dispute is resolved.

11.09           Value of Vertex Common Stock.  For all purposes of this Section 11 (including in connection with payment or satisfaction of indemnification Claims), the per share value of the

90

Vertex Common Stock in the Escrow Account or otherwise shall be equal to the Share Reference Price.

12.          Miscellaneous.

12.01           Disclosure Schedules. Sellers and the Equity Owner have prepared the schedules attached to this Agreement (individually, a "Schedule" and collectively, the "Disclosure Schedule") and delivered them to Buyers on the date hereof.  The Disclosure Schedule shall qualify the representations and warranties set forth in this Agreement and/or set forth other information required by this Agreement but shall not otherwise vary, change or alter the language of the representations and warranties contained in this Agreement. Any fact or item disclosed on any Schedule of the Disclosure Schedule shall be deemed to be disclosed on all Schedules of the Disclosure Schedule to which an appropriate cross reference is made or in all other Schedules where it is reasonably apparent on its face that such disclosure applies to such other Schedules of the Disclosure Schedule.

12.02           Amendment and Severability. This Agreement may be amended only by a written agreement of the Parties.  If any provision, clause or part of this Agreement or the application thereof under certain circumstances, is held invalid, the remainder of such provision and this Agreement, or the application of each provision, clause or part under other circumstances, shall not be affected thereby.

12.03           Waiver.  The failure of Buyers, on the one hand, or Sellers and the Equity Owner, on the other hand, to insist, in any one or more instances, upon performance of any of the terms or conditions of this Agreement, shall not be construed as a waiver or relinquishment of any rights granted hereunder or the future performance of any such term, covenant or condition.

12.04           Notices.  All notices, requests, demands and other communications under this Agreement shall be given in writing and shall be personally delivered; sent by facsimile or e-mail transmission; or sent by registered or certified U.S. mail, return receipt requested and postage prepaid; or by private overnight mail courier service, as follows:

12.05           Benefit.  This Agreement shall be binding upon and inure to the benefit and burden of and shall be enforceable by the Parties, and their successors and permitted assigns.  Notwithstanding the foregoing, (a) the lenders providing financing to Vertex and Buyers are beneficiaries of any liability cap or limitation on damages contained in this Agreement that are for the benefit of Vertex or Buyers and (b) such lenders are express third party beneficiaries of Section 12.06(d) of this Agreement. This Agreement may not be assigned by any Party without the written consent of the other Parties.  Notwithstanding the immediately preceding sentence, without the prior written consent of any Party, Vertex or either Buyer may at any time, in its sole discretion, assign, in whole or in part, its rights under this Agreement for collateral security purposes to any lender providing financing to Vertex, either Buyer or any of their Affiliates.

12.06           Dispute Resolution.  This Agreement shall be governed by the laws of the State of Delaware and the Federal laws of the United States without giving effect to any rule or provision thereof which would cause the application of the law of any other state.

92

the procedures specified in this Section 12.06; provided, however, nothing contained herein shall limit a Party's right to seek, in accordance with the terms of this Agreement, a decree of specific performance or to temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any of the provisions of this Agreement, without posting any bond or other undertaking.

(b)           Negotiations.  The Parties shall promptly attempt to resolve any Dispute by negotiations between Buyers and Sellers (or their Affiliates).  Either Buyers or Sellers may give the other party written notice of any Dispute not resolved in the normal course of business.  Representatives of Buyers (who may include the CEO or the CFO of Vertex) and Sellers (who may include the CEO or COO of Equity Owner) shall meet at a mutually acceptable time and place within 30 calendar days after delivery of such notice, and thereafter as often as they reasonably deem necessary, to exchange relevant information and to attempt to resolve the Dispute.  If a negotiator intends to be accompanied at a meeting by legal counsel, the other negotiator shall be given at least three Business Days prior notice of such intention and may also be accompanied by legal counsel.  If the Dispute has not been resolved by these Persons within 60 calendar days of the disputing party's notice, or if the parties fail to meet within such 30 calendar days, either Buyers or Sellers may initiate binding arbitration as provided in Section 12.06(c) below.

(c)           Arbitration.  If the Dispute is not resolved by negotiations pursuant to Section 12.06(b), all Disputes shall be determined by binding arbitration in New York, New York in accordance with the commercial rules of the American Arbitration Association ("AAA") then in effect unless the parties mutually agree in writing to waive this provision.  This Agreement to arbitrate shall be specifically enforceable under the prevailing arbitration law.  Notice of the demand for arbitration shall be filed in writing with the other Party or Parties to this Agreement and with the AAA in Chicago, Illinois.

The arbitration shall be before three arbitrators, one chosen by each of Buyers and Sellers and the third independent arbitrator chosen jointly by the other two arbitrators, who shall interpret this Agreement in accordance with the internal Laws of the State of Delaware without reference to any law thereof that would cause the application of the law of any other state.  The arbitrators shall each be a lawyer neutral as to each Party who is experienced in commercial and business affairs. The award rendered by the arbitrator shall be final and binding and any judgment may be entered upon it in accordance with the applicable law in any court having jurisdiction thereof.

(d)           Notwithstanding anything to the contrary contained herein, each party hereto hereby irrevocably agrees (i) that any dispute, claim or controversy of any kind or description, whether in law or in equity, whether in contract or in tort or otherwise, involving the lenders providing financing to Vertex and Buyers or any of their respective affiliates arising out of or relating to the transactions contemplated hereby shall be subject to the exclusive jurisdiction of any state or federal court sitting in the City of New York and (ii) to waive any right to trial by jury in respect of any such dispute, claim or controversy.

93

12.07           Waiver of Jury Trial.  EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

12.08           Counterparts.  This Agreement and any signed agreement or instrument entered into in connection with this Agreement, and any amendments hereto or thereto, may be executed in one or more counterparts, all of which shall constitute one and the same instrument.  Any such counterpart, to the extent delivered by means of a facsimile machine or by .pdf, .tif, .gif, .peg or similar attachment to electronic mail (any such delivery, an "Electronic Delivery") shall be treated in all manner and respects as an original executed counterpart and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person.  At the request of any Party, each other Party shall re-execute the original form of this Agreement and deliver such form to all other Parties.  No Party shall raise the use of Electronic Delivery to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of Electronic Delivery as a defense to the formation of a contract, and each such Party forever waives any such defense, except to the extent such defense relates to lack of authenticity.

12.09           Entire Agreement.  This Agreement (including the Schedules and Exhibits referred to herein which are hereby incorporated by reference) and the other agreements executed simultaneously herewith constitutes the entire agreement of the Parties with respect to the subject matter hereof and supersedes all prior agreements, understandings, and negotiations, written and oral, among the Parties with respect to the subject matter of this Agreement (including any letter of intent entered into among the Parties).  Except as explicitly set forth herein, neither this Agreement nor any provision hereof is meant to confer upon any person other than the parties hereto any rights or remedies hereunder.

THIS NONCOMPETITION AGREEMENT (this "Agreement") is made and entered into effective as of __________, 2014, by and among VERTEX REFINING LA, LLC, a Louisiana limited liability company ("Louisiana Buyer"), VERTEX REFINING NV, LLC, a Nevada limited liability company ("Bango Buyer;" and along with Louisiana Buyer, individually a "Buyer" and collectively, the "Buyers"), OMEGA REFINING, LLC, a Delaware limited liability company ("Omega"), BANGO REFINING NV, LLC, a Delaware limited liability company ("Bango Refining;" and along with Omega, each a "Seller" and collectively, the "Sellers"), and OMEGA HOLDINGS COMPANY LLC, a Delaware limited liability company (the "Equity Owner").

RECITALS

A.           Buyers have agreed to purchase substantially all of the assets of Sellers used in connection with the operation of its business of (1) operating oil re-refineries and, in connection therewith, purchasing used lubricating oils and re-refining such oils into processed oils and other products for the distribution, supply and sale to end-customers and (2) the provision of related products and support services (the "Business"), pursuant to the terms and conditions of an Asset Purchase Agreement made and entered into as of March __, 2014 by and among Vertex Energy, Inc., a Nevada corporation, Buyers, Sellers and the Equity Owner (the "Purchase Agreement").

B.           The Equity Owner will benefit from the consummation of the transactions contemplated by the Purchase Agreement.  The value of the Business would be diminished substantially if Sellers or the Equity Owner were to compete with the Business and Buyers after the closing of the transactions contemplated by the Purchase Agreement.

C.           In light of each Seller's and the Equity Owner's intimate knowledge of the Business and relations with customers, suppliers, employees and others having business dealings with the Business, each Seller and the Equity Owner acknowledges that its competition with the Business within a reasonable period of time after the date of this Agreement, or disclosure or use of Confidential Information (as defined below) after the date of this Agreement, would cause Buyers and its affiliates to suffer significant and irreparable damage, including damage resulting from a significant decrease in the value of the Business.

D.           The execution and delivery of this Agreement by each Seller and the Equity Owner is a condition to the obligations of Buyers to consummate the transactions contemplated by the Purchase Agreement.

AGREEMENTS

In consideration of the Recitals and covenants set forth in this Agreement and the receipt of substantial consideration as a result of the transactions contemplated by the Purchase

Agreement and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, the parties agree as follows:

1.           Definitions.  Capitalized terms not expressly defined in this Agreement shall have the meanings given to them in the Purchase Agreement.  For purposes of this Agreement:

(a)           "Active Customer" means any customer of the Business as of the date hereof and any prospective customer of the Business that any employee or agent of either Seller actively solicited during the 12-month period immediately preceding the date of this Agreement.

(b)           "Competitive Business" means any person or entity, including Sellers or the Equity Owner, (i) that competes directly, or becomes engaged in a business that competes directly, with Buyers with respect to the Business, and, with respect to the Equity Owner, which business or other competitive activities was within the Equity Owner's management, operational, marketing, purchasing or sales responsibility, including the responsibility of personnel reporting directly to management personnel of the Equity Owner, or about which the Equity Owner (or its management personnel) received any Confidential Information or trade secrets at any time within twelve (12) months prior to the date of this Agreement, and (ii) which engages or becomes engaged in such competitive business in any location or geographic region in which either Seller had engaged in the Business within the twelve (12) months prior to the date hereof.

(c)           "Confidential Information" means information, whether or not a trade secret, possessed by or developed for (pursuant to a confidential arrangement) either Seller and that relates to the Business, including but not limited to, Inventions (as defined below), business plans and strategies, existing or proposed bids, technical or engineering developments, existing or proposed research projects, financial or business projections, investments, marketing plans and strategies, pricing and cost information, negotiation strategies, training information and materials, employee compensation and other employee information, customer or potential customer lists, customer purchasing history and information generated for customer engagements.  Confidential Information also includes information received by the Business from others, which either Seller has an obligation to treat as confidential, including all information obtained in connection with customer engagements.  Notwithstanding anything to the contrary in this Agreement, Confidential Information shall not include information that is or becomes generally known to the public (without violation of this Agreement).

(d)           "Inventions" means all inventions, original works of authorship, developments, concepts, improvements, designs, discoveries, ideas, processes, techniques, formulae, trademarks, data and other intellectual property other than trade secrets (whether or not protectable under intellectual property laws or similar laws) made solely by either Seller's agents and affiliates (or jointly with others) that (i) relate to the Business; or (ii) were developed or conceived using the assets of the Business.

(e)           "Noncompetition Period" means the five (5) year period commencing on the date hereof.

2.           Acknowledgments by Sellers and the Equity Owner.  Each Seller and the Equity Owner (each, a "Restricted Party" and collectively, the "Restricted Parties") acknowledge and

2

agree that: (a) Buyers have required that the Restricted Parties make the covenants set forth in Sections 3 and 4 of this Agreement as a condition to the purchase of the assets by Buyers contemplated by the Purchase Agreement; (b) the covenants contained herein are being entered into in connection with the sale of the Business and not in connection with employment or any other principal-agent relationship; (c) the provisions of Sections 3 and 4 of this Agreement are reasonable and necessary to protect and preserve the Business that was acquired by Buyers; (d) Buyers and the Business would be irreparably damaged if any Restricted Party were to breach the covenants set forth in Sections 3 and 4 of this Agreement; and (e) the consideration provided by Buyers to Sellers in connection with the transactions contemplated by the Purchase Agreement is sufficient to fully and adequately compensate each Seller and the Equity Owner for agreeing to the terms and restrictions of this Agreement.

3.           Confidential Information.  Each Restricted Party acknowledges and agrees that the Confidential Information is the property of Buyers and the Business and constitutes a Purchased Asset under the terms of the Purchase Agreement, has been established and maintained at great expense, and is of great value to the Business.  Therefore, each Restricted Party agrees that it will not, directly or indirectly (through its agents or controlling persons), in the territory or geographic region where such Restricted Party's use or disclosure of the Confidential Information would reasonably be expected to materially harm any Buyer (or its Affiliate) or the Business, disclose to any unauthorized persons or use for its own benefit or for the benefit of any third party any Confidential Information without Buyers' prior written consent, until the earlier of (a) such time as the Confidential Information no longer provides a benefit to a Buyer or the Business, (b) the date the Confidential Information is or becomes generally known to and available for use by the public other than by the fault of any Restricted Party (or any of its agents or controlling persons) or (c) the end of the Noncompetition Period; provided, however, the Restricted Parties may disclose any Confidential Information as is required by subpoena or other legal process or in response to any governmental inquiry, proceeding or investigation; and provided, further, that such Restricted Party shall promptly notify Buyers of such request and, if possible, prior to disclosure so that Buyers may take appropriate action to safeguard such Confidential Information.  At Buyers reasonable request, the Restricted Parties agree to deliver to Buyers all tangible copies of, and destroy all digital copies of (certifying to Buyers in writing such destruction or delivery), all documents, memoranda, notes, plans, records, reports, and other documentation, models, components, devices or computer software (and all copies of all of the foregoing), relating to the Business and any other Confidential Information that any Restricted Party may then possess or have under its control.  Nothing in this Agreement reduces any obligation of the Restricted Parties to comply with applicable laws or orders relating to trade secrets, confidential information and unfair competition.  If, at any time on or after the date of this Agreement, any Restricted Party discovers that such Restricted Party is in possession of any records containing any Confidential Information, then such Restricted Party shall immediately deliver such records to Buyers, without retaining any copy or summary thereof.

4.           Noncompetition; Nonsolicitation.  Each Restricted Party (and each controlling person or Affiliate of Restricted Party) agrees as follows:

(a)           During the Noncompetition Period, such person will not, directly or indirectly, in any capacity, either individually, or as agent, principal, partner, member, manager, owner, trustee, beneficiary, co-venturer, distributor, consultant on its own behalf or on behalf of

3

any other corporation, limited liability company, partnership, proprietorship, firm, association or other business entity:

(i)           participate in, provide assistance to, or have a financial or other interest in any Competitive Business; provided, however, that the ownership of less than a 2% interest in an entity whose securities are traded on a recognized stock exchange or traded in the over-the-counter market, even though that entity is a competitor of the Business, shall not be deemed in itself to be a breach of this Section 4(a)(i);

(ii)           except on behalf of the Business, make an offer to, solicit or induce or attempt to make an offer to, solicit or induce any person who is an employee, officer, agent, customer, supplier or other business relation of the Business to terminate, withdraw, curtail or cancel such relationship with any Buyer or the Business or to breach any agreement with any Buyer or the Business; provided, however, that publication of general solicitations not targeted [a] to an individual employee, sales representative, consultant or other agent of the Business or either Buyer or [b] solely to employees, sales representatives, consultants or other agents of the Business or either Buyer, shall not constitute a violation of this Section 4(a)(ii);

(iii)           make any disparaging remarks about any Buyer or the Business or their officers, directors, affiliates or employees;

(iv)           solicit or accept any business that is competitive with the Business from any Active Customer or other business contact of the Business or advise any person or entity with respect to any such solicitation; and/or

(v)           engage in any practice the purpose of which is to evade the provisions of these foregoing covenants.

(b)           Each Restricted Party agrees that the covenants set forth in the subsections of Section 4 are each reasonable with respect to its duration, geographical area, and scope.

5.           Priority of Covenants.  Each Restricted Party's covenants in this Agreement are not intended to supersede any covenant or agreement given in the Purchase Agreement or any other agreement executed by such Restricted Party in connection with the closing of the transactions contemplated under the Purchase Agreement, and the covenants herein shall be cumulative with respect to the covenants and agreements in the Purchase Agreement or in any such other agreement.

6.           Operation of Bango Refining's Business.  The parties acknowledge and agree that nothing contained in this Agreement shall prohibit Bango Refining and the Equity Owner from continuing to operate the portion of the Business related to such Seller until the Second Closing (but not thereafter), provided that such operation is consistent with the covenants and agreements contained in the Purchase Agreement.

7.           Remedies.  If a Restricted Party breaches any of the covenants set forth in Sections 3 or 4 of this Agreement, Buyers will be entitled to (a) any money damages proved and awarded by a trier of fact, arbitrator or mediator or otherwise agreed to by the parties, and (b) injunctive or other equitable relief to restrain any breach or threatened breach or otherwise to

4

specifically enforce the provisions of Sections 3 and 4 of this Agreement, without the necessity to post any bond, it being agreed that money damages alone would be inadequate to compensate Buyers and would be an inadequate remedy for such breach.  Without limiting the foregoing, the parties agree that the rights and remedies of the parties to this Agreement are cumulative and not alternative.  If a court of competent jurisdiction finally determines that a Restricted Party has breached this Agreement, in addition to and not in lieu of any other remedies available in connection with any suit at law or in equity, Buyers will be entitled to an accounting, and to the repayment of all profits, compensation, commissions, fees, royalties or other remuneration which such person, or any other person, may have either directly or indirectly realized and/or may realize, as a result of, growing out of, or in connection with such violation.  In addition to the foregoing, Buyers will be entitled to collect from each Restricted Party any reasonable attorneys' fees and costs incurred in bringing any action to enforce the terms of this Agreement against such person, as well as any attorneys' fees and costs for the collection of any judgments in favor of Buyers or their respective affiliates arising out of this Agreement.

8.           Trade Secrets.  The parties agree that nothing in this Agreement shall be construed to limit or negate any common or statutory law regarding torts or trade secrets where it provides Buyers or the Business with broader protection than that provided herein.  Each Restricted Party shall take all reasonable steps necessary to prevent unauthorized misappropriation or disclosure of the trade secrets of the Business and shall not use or disclose such trade secrets as long as they remain trade secrets.

1

Term (each an “Automatic Renewal Term”) in the event that neither party provides the other written notice of their intent not to automatically extend such Agreement at least sixty (60) days prior to such Automatic Renewal Date.

1.2.           Duties and Responsibilities.  Employee, as [TITLE], shall perform such administrative, managerial and employment duties for the Company and its affiliates (i) as are consistent with those currently performed by Employee and more specifically including, but not limited to, those enumerated in Exhibit A attached, and (ii) as may be reasonably assigned from time to time by the President and Chief Executive Officer of the Parent Corporation with the consent of the Employee, which shall be granted unless any such assignment constitutes an unreasonable expansion of Employee’s duties and responsibilities beyond those he is currently performing in his capacity as employee of Sellers.  Employment shall be part-time meaning that Employee shall not be obligated to devote all of Employee’s time or efforts to the Company and shall be permitted to work for other companies, subject to the restrictions set forth in Section 1.3 below; provided, however, Employee shall on average during the Initial Term work a minimum of [15/20] hours per week in performing his employment duties for the benefit of the Company and its affiliates hereunder.
