        Interest. Lender may at any time, and without further authorization from Borrower, file a carbon, photograph, facsimile, or other reproduction of any financing statement for use as a financing statement. Borrower will reimburse Lender for all
        expenses for  the  perfection, termination, and the continuation of the perfection of Lender's security interest in the Collateral. Borrower promptly will notify Lender before any change in Borrower's name including any change to the assumed
        business names of Borrower. Borrower also promptly will notify Lender before any change in Borrower's Social Security Number or Employer Identification Number. Borrower further agrees to notify Lender in writing prior to any change in address or
        location of Borrower's principal governance office or should Borrower merge or consolidate with any other entity.

      Collateral Records. Borrower does now, and at all times hereafter shall, keep correct and accurate records of the Collateral, all of which records shall be available to Lender or Lender's representative upon demand for inspection
        and copying at any reasonable time. With respect to the Accounts, Borrower agrees to keep and maintain such records as Lender may require, including without  limitation  information concerning Eligible Accounts and Account balances and agings.

        Borrower or to any other person. The representations and warranties contained herein are based on Borrower's due diligence in investigating the Collateral for hazardous waste and Hazardous Substances. Borrower hereby (1) releases and waives any
        future claims against Lender for indemnity or  contribution in  the  event  Borrower becomes liable for cleanup or other costs under any such laws, and (2) agrees to indemnify, defend, and hold harmless Lender against any and all claims, losses,
        liabilities, damages, penalties, and expenses which Lender may directly or indirectly sustain or suffer resulting from a breach of this section of the Agreement or as a consequence of any use, generation, manufacture, storage, disposal, release or
        threatened release of a hazardous waste or substance on the Collateral. The provisions of this section of the Agreement, including the obligation to indemnify and defend, shall survive the payment of the Indebtedness and the termination, expiration
        or satisfaction of this Agreement and shall not be affected by Lender's acquisition of any interest in any of the Collateral, whether by  foreclosure or otherwise.

      Litigation and Claims. No litigation, claim, investigation, administrative proceeding or similar action (including those for unpaid taxes) against Borrower is pending or threatened, and no other event has occurred which may
        materially adversely affect Borrower's financial condition or properties, other than litigation, claims, or other events, if any, that have been disclosed to and acknowledged by Lender in writing.

      Taxes.   To the best of Borrower's knowledge, all of Borrower's tax returns and reports that are or were required to be filed, have been   filed, and all taxes, assessments and other governmental charges have been paid in full,
        except those presently being or to be contested by Borrower in good faith in the ordinary course of business and for which adequate reserves have been provided.

      Lien Priority. Unless otherwise previously disclosed to Lender in writing, Borrower has not entered into or granted any Security Agreements, or permitted the filing or attachment of any Security Interests on or affecting any of the
        Collateral  directly  or  indirectly  securing repayment of Borrower's Loan and Note, that would be prior or that may in any way be superior to Lender's Security Interests and rights in and to such Collateral.

      Binding Effect. This Agreement, the Note, all Security Agreements (if any), and all Related Documents are binding upon the signers thereof, as well as upon their successors, representatives and assigns, and are legally enforceable
        in accordance with their respective terms.

      Interim Statements. As soon as available, but in no event later than thirty (30) days after the end of each fiscal quarter, Borrower's balance sheet and profit and loss statement for the period ended, prepared by Borrower.

      Additional
          Information. Furnish such additional information and statements, as Lender may request from time to time.

      Insurance. Maintain fire and other risk insurance, public liability insurance, and such other insurance as Lender may require with respect to Borrower's properties and operations, in form, amounts, coverages and with insurance

        diminished without at least thirty (30) days prior written notice to  Lender.  Each  insurance policy also shall include an endorsement providing that coverage in favor of Lender will not be impaired in any way by any act, omission or default of
        Borrower or any other person. In connection with all policies covering assets in which Lender holds or is offered a security interest for the Loans, Borrower will provide Lender with such lender's loss payable or other endorsements as Lender may
        require.

      Insurance Reports. Furnish to Lender, upon request of Lender, reports on each existing insurance policy showing such information as Lender may reasonably request, including without limitation the following: (1) the name of the
        insurer;  (2)  the risks insured;  (3)  the  amount of the policy; (4) the properties insured; (5)  the then current property values on the basis of which insurance has been obtained,  and the manner of determining those values; and (6) the
        expiration date of the policy. In addition, upon request of Lender (however not  more often than annually), Borrower will have an independent appraiser satisfactory to Lender determine, as applicable, the actual cash value or replacement cost of
        any Collateral. The cost of such appraisal shall be paid by Borrower.

      Other Agreements. Comply with all terms and conditions of all other agreements, whether now or hereafter existing, between Borrower  and any other party and notify Lender immediately in writing of any default in connection with any
        other such agreements.

      levy, lien or claim so long as (1) the legality of the same shall be contested in good
        faith by appropriate proceedings, and  (2)  Borrower  shall have established on Borrower's books adequate reserves with respect to such contested assessment, tax, charge, levy, lien, or claim  in accordance with GAAP.

      Performance. Perform and comply, in a timely manner, with all terms, conditions, and provisions set forth in this Agreement, in the Related Documents, and in all other instruments and agreements between Borrower and Lender.

      Operations. Maintain executive and management personnel with substantially the same qualifications and experience as the present executive and management personnel; provide written notice to Lender of any change in executive and
        management personnel; conduct its business affairs in a reasonable and prudent manner.

      Environmental Studies. Promptly conduct and complete, at Borrower's expense, all such investigations, studies, samplings and testings as may be requested by Lender or any governmental authority relative to any substance, or any
        waste or by-product of any substance defined as toxic or a hazardous substance under applicable federal, state, or local law, rule, regulation, order or directive, at or affecting any  property or any facility owned, leased or used by Borrower.

      Compliance with Governmental Requirements. Comply with all laws, ordinances, and regulations, now or hereafter in effect, of all governmental authorities applicable to the conduct of Borrower's properties, businesses and
        operations, and to the use or occupancy of the Collateral, including without limitation, the Americans With Disabilities Act.   Borrower may contest in good faith any such law,  ordinance,   or regulation and withhold compliance during any
        proceeding, including appropriate appeals, so long as Borrower has notified Lender in writing prior to doing so and so long as, in Lender's sole opinion, Lender's interests in the Collateral are not jeopardized.  Lender may  require Borrower to
        post adequate security or a surety bond, reasonably satisfactory to Lender, to protect Lender's interest.

      Inspection. Permit employees or agents of Lender at any reasonable time to inspect any and all Collateral for the Loan or Loans and Borrower's other properties and to examine or audit Borrower's books, accounts, and records and to
        make copies and memoranda of Borrower's books, accounts, and records. If Borrower now or at any time hereafter maintains any records (including without limitation computer generated records and computer software programs for the generation of such
        records) in the possession of a third party,  Borrower, upon request of Lender, shall notify such party to permit Lender free access to such records at all reasonable times and to  provide Lender with copies of any records it may request, all at
        Borrower's expense.

      Environmental Compliance and Reports. Borrower shall comply in all respects with any and all Environmental Laws; not cause or permit to exist, as a result of an intentional or unintentional action or omission on Borrower's part or
        on the part  of any  third party,  on  property owned and/or occupied by Borrower, any environmental activity where damage may result to the environment, unless such environmental activity is pursuant to and in compliance with the conditions of a
        permit issued by the appropriate federal, state or local governmental authorities; shall furnish to Lender promptly and in any event within thirty (30) days after receipt thereof  a copy of any notice, summons,  lien, citation, directive, letter or
        other communication from any governmental agency or instrumentality concerning any intentional or unintentional action or omission on Borrower's part in connection with any environmental activity whether or not there is damage to the environment
        and/or other natural resources.

      Additional Assurances. Make, execute and deliver to Lender such promissory notes, mortgages, deeds of trust, security agreements, assignments, financing statements, instruments, documents and other agreements as Lender or its
        attorneys may reasonably request to evidence and secure the Loans and to perfect all Security Interests.

      LENDER'S EXPENDITURES. If any action or proceeding is commenced that would materially affect Lender's interest in the Collateral or if Borrower fails to comply with any provision of this Agreement or any Related Documents,
        including but not limited to Borrower's failure to discharge or pay when due any amounts Borrower is required to discharge or pay under this Agreement or any Related Documents, Lender on Borrower's behalf may (but shall not be obligated to) take
        any action that Lender deems appropriate, including but not limited to discharging or paying all taxes, liens, security interests, encumbrances and other claims, at any time levied or placed on any Collateral and paying all costs for insuring,
        maintaining and preserving any Collateral. All such expenditures incurred or paid by Lender for such purposes will then bear interest at the rate charged under the Note or at the highest rate authorized by law, from the date incurred or paid by
        Lender to the date of repayment by Borrower. All such expenses will become a part of the Indebtedness and, at Lender's option, will (A) be payable on demand;  (B)  be added to  the balance of the Note and be apportioned among and be payable with
        any installment payments to become due during either (1) the term of any applicable insurance policy; or  (2)  the remaining term of the Note; or  (C)  be treated as a balloon payment which will be due and payable  at the Note's maturity. If Lender
        is required by law to give Borrower notice before or after Lender makes an expenditure, Borrower agrees that notice sent by regular mail at least five (5) days before the expenditure is made or notice delivered two (2) days before the expenditure
        is made  is sufficient, and that notice within sixty (60) days after the expenditure is made is reasonable.

      NEGATIVE COVENANTS. Borrower covenants and agrees with Lender that while this Agreement is in effect, Borrower shall not, without the prior written consent of Lender:

      Indebtedness and Liens. (1) Except for trade debt incurred in the normal course of business and indebtedness to Lender contemplated by this Agreement, create, incur or assume indebtedness for borrowed money, including capital
        leases, (2) sell, transfer, mortgage, assign, pledge, lease, grant a security interest in, or encumber any of Borrower's assets (except as allowed as Permitted Liens), or (3) sell with recourse any of Borrower's accounts, except to Lender.

          Operations. (1) Engage in any business activities substantially different than those in which Borrower is presently engaged,

      
        	
                (2)

              	
                cease operations, liquidate, merge or restructure as a legal entity (whether by division or
                  otherwise), consolidate with or acquire any other entity, change its name, convert to another type of entity or redomesticate, dissolve or transfer or sell Collateral out of the ordinary course of business, or (3) pay any dividends on
                  Borrower's stock (other than dividends payable in its stock), provided, however that notwithstanding the foregoing, but only so long as no Event of Default has occurred and is continuing or would result from the payment of dividends, if
                  Borrower is a "Subchapter S Corporation" (as defined in the Internal Revenue Code of 1986, as amended), Borrower may pay cash dividends on its stock to its shareholders from time to time in amounts necessary to enable the shareholders to
                  pay income taxes and make estimated income tax payments to satisfy their liabilities under federal and state law which arise solely from their status as Shareholders of a Subchapter S Corporation because of their ownership of shares of
                  Borrower's stock, or purchase or retire any of Borrower's outstanding shares or alter or amend Borrower's capital structure.

              


      

      Loans, Acquisitions and Guaranties. (1) Loan, invest in or advance money or assets to any other person, enterprise or entity, (2) purchase, create or acquire any interest in any other enterprise or entity, or (3)  incur  any
        obligation as surety  or guarantor other than in  the ordinary course of business.

      Agreements. Enter into any agreement containing any provisions which would be violated or breached by the performance of Borrower's obligations under this Agreement or in connection herewith.

      CESSATION OF ADVANCES. If Lender has made any commitment to make any Loan to Borrower, whether under this Agreement or under any other agreement, Lender shall have no obligation to make Loan Advances or to disburse Loan proceeds
        if: (A) Borrower or any Guarantor is in default under the terms of this Agreement or any of the Related Documents or any other agreement that Borrower or any Guarantor has with Lender;  (B)  Borrower or any Guarantor dies, becomes incompetent or
        becomes insolvent, files a petition in bankruptcy or similar proceedings,  or is adjudged a bankrupt; (C) there occurs a material adverse change in Borrower's financial condition, in the financial condition of any Guarantor, or in the value of any
        Collateral securing any Loan; or (D) any Guarantor seeks, claims or otherwise attempts to limit, modify or  revoke such Guarantor's guaranty of the Loan or any other loan with Lender; or (E) Lender in good faith deems itself insecure, even though
        no Event of Default shall have occurred.

      RIGHT OF SETOFF. To the extent permitted by applicable law, Lender reserves a right of setoff in all Borrower's accounts with Lender (whether checking, savings, or some other account). This includes all accounts Borrower holds
        jointly with someone else and all accounts Borrower may open in the future.  However, this does not include any IRA or Keogh accounts, or any trust accounts for which setoff would be prohibited by   law. Borrower authorizes Lender, to the extent
        permitted by applicable law, to charge or setoff all sums owing on the Indebtedness against any and all such accounts.

      DEFAULT. Each of the following shall constitute an Event of Default under this Agreement:

      Other Defaults.  Borrower fails to comply with or to perform any other term, obligation, covenant or condition contained in this Agreement  or in any of the Related Documents or to comply with or to perform any term, obligation,
        covenant or condition contained in any other agreement between Lender and Borrower.

      Default in Favor of Third Parties. Borrower or any Grantor defaults under any loan, extension of credit, security agreement, purchase or sales agreement, or any other agreement, in favor of any other creditor or person that may
        materially affect any of Borrower's or any Grantor's property or Borrower's or any Grantor's ability to repay the Loans or perform their respective obligations under this Agreement or any of the Related Documents.

      False Statements. Any warranty, representation or statement made or furnished to Lender by Borrower or on Borrower's behalf under this Agreement or the Related Documents is false or misleading in any material respect, either now or
        at the time made or furnished or becomes false or misleading at any time thereafter.

      Insolvency. The dissolution or termination of Borrower's existence as a going business, the insolvency of Borrower, the appointment of a receiver for any part of Borrower's property, any assignment for the benefit of creditors, any
        type of creditor workout,  or  the  commencement of any proceeding under any bankruptcy or insolvency laws by or against Borrower.

      Defective Collateralization. This Agreement or any of the Related Documents ceases to be in full force and effect (including failure of any collateral document to create a valid and perfected security interest or lien) at any time
        and for any reason.

      Creditor or Forfeiture Proceedings. Commencement of foreclosure or forfeiture proceedings, whether by judicial proceeding, self-help, repossession or any  other method, by  any creditor  of Borrower  or by any  governmental agency 
        against any collateral  securing the  Loan.    This  includes  a garnishment  of  any of  Borrower's accounts,  including  deposit accounts,  with Lender.  However,  this  Event of  Default shall  not apply if there is a good faith dispute by
        Borrower as to the validity or reasonableness of the claim which is the basis  of  the creditor  or  forfeiture proceeding and if Borrower gives Lender written notice of the creditor or forfeiture proceeding and deposits with Lender monies or     
              a surety bond for the  creditor or forfeiture proceeding,  in an amount determined by  Lender, in its  sole  discretion, as  being an adequate    reserve or bond for the dispute.

      Events Affecting Guarantor. Any of the preceding events occurs with respect to any Guarantor of any of the Indebtedness or any Guarantor dies or becomes incompetent, or revokes or disputes the validity of, or liability under, any
        Guaranty of the Indebtedness.

      Change in
          Ownership. Any change in ownership of twenty-five percent (25%) or more of the common stock of Borrower.

      Adverse Change. A material adverse change occurs in Borrower's financial condition, or Lender believes the prospect of payment or performance of the Loan is impaired.

      Insecurity. Lender
        in good faith believes itself insecure.

      Right to Cure. If any default, other than a default on Indebtedness, is curable and if Borrower or Grantor, as the case may be, has not been given a notice of a similar default within the preceding twelve (12) months, it may be
        cured if Borrower or Grantor, as the case may be,    after Lender sends written notice to Borrower or Grantor, as the case may be, demanding cure of such default: (1) cure the default within  ten (10) days; or (2) if the cure requires more than ten
        (10) days, immediately initiate steps which Lender deems  in  Lender's  sole  discretion to be sufficient to cure the default and thereafter continue and complete all reasonable and necessary steps sufficient to produce compliance as soon as
        reasonably practical.

      EFFECT OF AN EVENT OF DEFAULT. If any Event of Default shall occur, except where otherwise provided in this Agreement or the Related Documents, all commitments and obligations of Lender under this Agreement or the Related Documents
        or any other agreement immediately will terminate (including any obligation to make further Loan Advances or disbursements), and, at Lender's option, all Indebtedness immediately will become due and payable, all without notice of any kind to
        Borrower, except that in the case of an Event of Default of the type described in the "Insolvency" subsection above, such acceleration shall be automatic and not optional. In addition, Lender shall have all the rights and remedies provided in the
        Related Documents or available at law, in equity, or otherwise. Except as may be prohibited by applicable law, all of Lender's rights and remedies shall be cumulative and may be exercised singularly or concurrently. Election by Lender to pursue any
        remedy shall not exclude pursuit of any other remedy, and an election to make expenditures or to take action to perform an obligation of Borrower or of any Grantor shall not affect Lender's right to declare a default and to exercise its rights and
        remedies.

      NON-USE FEE. Quarterly
        non-use fee of 25 basis points.

      FIXED CHARGE COVERAGE RATIO REQUIREMENT. A fixed charge coverage ratio of 1.25:1 is required and will be tested annually beginning 09/30/2020. Fixed Charge Coverage Ratio to be defined as follows: EBITDA plus capital contributions,
        plus non-cash expenses, plus on-time expenses, less total distributions, divided by principal and interest payments on all outstanding debt, plus capital expenditures (CAPEX).

      ADDITIONAL
          INDEBTEDNESS REQUIREMENT. Any additional indebtedness require approval from Vast Bank N.A. d/b/a Valley National Bank.

      Amendments. This Agreement, together with any Related Documents, constitutes the entire understanding and agreement of the parties  as to the matters set forth in this Agreement. All prior and contemporaneous representations and
        discussions concerning such matters  either are included in this document or do not constitute an aspect of the agreement of the parties.  Except as may be specifically set forth  in this Agreement, no conditions precedent or subsequent, of any
        kind whatsoever, exist with respect to Borrower's obligations under this Agreement. No alteration of or amendment to this Agreement shall be effective unless given in writing and signed by the party or parties sought to be charged or bound by the
        alteration or amendment.

      Attorneys' Fees; Expenses. Borrower agrees to pay upon demand all of Lender's costs and expenses, including Lender's attorneys' fees and Lender's legal expenses, incurred in connection with the enforcement of this Agreement. Lender
        may hire or pay someone else to help enforce this Agreement, and Borrower shall pay the costs and expenses of such enforcement. Costs and expenses include Lender's attorneys' fees and legal expenses whether or not there is a lawsuit, including
        attorneys' fees and legal expenses for bankruptcy  proceedings (including efforts to modify or vacate any automatic stay or injunction), appeals, and any anticipated post-judgment collection services. Borrower also shall pay all court costs and
        such additional fees as may be directed by the court.

      Caption Headings. Caption headings in this Agreement are for convenience purposes only and are not to be used to interpret or define the provisions of this Agreement.

      Consent to Loan Participation. Borrower agrees and consents to Lender's sale or transfer, whether now or later, of one or more participation interests in the Loan to one or more purchasers, whether related or unrelated to Lender.
        Lender may provide, without any limitation whatsoever, to any one or more purchasers, or potential purchasers, any information or knowledge Lender may have about Borrower or about any other matter relating to the Loan, and Borrower hereby waives
        any rights to privacy Borrower may have with respect to such matters.  Borrower additionally waives any and all notices of sale of participation interests, as well as all notices of any repurchase  of such participation interests. Borrower also
        agrees that the purchasers of any such participation interests will be considered as the absolute owners of such interests in the Loan and will have all the rights granted under the participation agreement or  agreements governing the sale of such
        participation interests. Borrower further waives all rights of offset or counterclaim that it may have now or later against Lender or against any purchaser of such a participation interest and unconditionally agrees that either Lender or such
        purchaser may enforce Borrower's obligation under the Loan irrespective of the failure or insolvency of any holder of any interest in the Loan. Borrower further agrees that the purchaser of any such participation interests may enforce its interests
        irrespective of any personal claims  or  defenses that Borrower may have against Lender.

      Governing Law. This Agreement will be governed by federal law
        applicable to Lender and, to the extent not preempted by federal law, the laws of the State of Oklahoma without regard to its conflicts of law provisions. This Agreement has been accepted by Lender in the State of Oklahoma.

      Choice of Venue. If there is a lawsuit, Borrower agrees upon Lender's request to submit to the jurisdiction of the courts of TULSA County, State of Oklahoma.

      Joint and Several Liability. All obligations of Borrower under this Agreement shall be joint and several, and all references to Borrower shall mean each and every Borrower. This means that each Borrower signing below is responsible
        for all obligations in this Agreement. Where any one or more of the parties is a corporation, partnership, limited liability company or similar entity, it is not  necessary for Lender to  inquire into the powers of any of the officers, directors,
        partners, members, or other agents acting or purporting to  act on  the  entity's  behalf, and any obligations made or created in reliance upon the professed exercise of such powers shall be guaranteed under this Agreement.

      No Waiver by Lender. Lender shall not be deemed to have waived any rights under this Agreement unless such waiver is given in writing and signed by Lender. No delay or omission on the part of Lender in exercising any right shall
        operate as a waiver of such right or  any  other right. A waiver by Lender of a provision of this Agreement shall not prejudice or constitute a waiver of Lender's right otherwise to demand strict compliance with that provision or any other
        provision of this Agreement.   No prior waiver by Lender, nor any course of   dealing between Lender and Borrower, or between Lender and any Grantor, shall constitute a waiver of any of Lender's rights or of any of Borrower's or any Grantor's
        obligations as to any future transactions.  Whenever the consent of Lender is required under this Agreement,  the granting of such consent by Lender in any instance shall not constitute continuing consent to subsequent instances where such consent
        is required and in all cases such consent may be granted or withheld in the sole discretion of Lender.

      Notices.  To the extent permitted by applicable law, any notice required to be given under this Agreement shall be given in writing, and   shall be effective when actually delivered, when actually received by telefacsimile (unless
        otherwise required by law), when deposited with   a nationally recognized overnight courier, or, if mailed, when deposited in the United States mail, as first class, certified or registered mail postage prepaid, directed to the addresses shown near
        the beginning of this Agreement. Any party may change its address for notices

      under this Agreement by giving formal written notice to the other parties, specifying
        that the purpose of the notice is to change the party's address. For notice purposes, Borrower agrees to keep Lender informed at all times of Borrower's current address.  To  the  extent  permitted by applicable law, if there is more than one
        Borrower, any notice given by Lender to any Borrower is deemed to be notice given   to all Borrowers.

      Severability. If a court of competent jurisdiction finds any provision of this Agreement to be illegal, invalid, or unenforceable as to any person or circumstance, that finding shall not make the offending provision illegal,
        invalid, or unenforceable as to any other person or circumstance. If feasible, the offending provision shall be considered modified so that it becomes legal, valid and enforceable. If the offending provision cannot be so modified, it shall be
        considered deleted from this Agreement. Unless otherwise required by law, the illegality, invalidity, or unenforceability of any provision of this Agreement shall not affect the legality, validity or enforceability of any other provision of this
