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.

request to evidence and secure the Loans and to perfect all Security Interests.

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.



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.



Continuity of Operations. (1) Engage in any business activities substantially different than those in which Borrower is presently engaged, (2)
cease operations, liquidate, merge, transfer, acquire or consolidate with any other entity, change its name, 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, or advance money or assets to any other person, enterprise or entity, or (3) incur any obligation as
surety or guarantor other than in the ordinary course of business.



Agreements. Borrower will not 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.



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



Payment Default. Borrower fails to make any
payment when due under the Loan.



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. In the event of a death, Lender, at its option, may, but shall not be required to, permit the Guarantors estate to assume
unconditionally the obligations arising under the guaranty in a manner satisfactory to Lender, and, in doing so, cure any Event of Default.



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 (and no Event of Default will have occurred) if Borrower or Grantor, as the case may be, after receiving written notice from
Lender demanding cure of such default: (1) cure the default within fifteen (15) days; or (2) if the cure requires more than fifteen (15) 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.

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. 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. Unless otherwise provided or
required by 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
circumstance, that finding shall not make the offending provision illegal, invalid, or unenforceable as to any other 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 Agreement.



Subsidiaries and Affiliates of Borrower. To the extent the context of any provisions of this Agreement makes it appropriate, including without limitation any representation, warranty or covenant, the word Borrower as used
in this Agreement shall include all of Borrowers subsidiaries and affiliates. Notwithstanding the foregoing however, under no circumstances shall this Agreement be construed to require Lender to make any Loan or other financial accommodation
to any of Borrowers subsidiaries or affiliates.



Successors and Assigns. All covenants and agreements by or on behalf of Borrower contained in this Agreement or any Related Documents shall bind Borrowers successors and assigns and shall inure to the benefit of Lender and its
successors and assigns. Borrower shall not, however, have the right to assign Borrowers rights under this Agreement or any interest therein, without the prior written consent of Lender.



Survival of Representations and Warranties. Borrower understands and
agrees that in extending Loan Advances, Lender is relying on all representations, warranties, and covenants made by Borrower in this Agreement or in any certificate or other instrument delivered by Borrower to Lender under this Agreement or the
Related Documents. Borrower further agrees that regardless of any investigation made by Lender, all such representations, warranties and covenants will survive the extension of Loan Advances and delivery to Lender of the Related Documents, shall be
continuing in nature, shall be deemed made and redated by Borrower at the time each Loan Advance is made, and shall remain in full force and effect until such time as Borrowers Indebtedness shall be paid in full, or until this Agreement shall
be terminated in the manner provided above, whichever is the last to occur.



Time is of the Essence. Time is of the essence in the performance of this Agreement.



Waive Jury. All parties to this Agreement hereby waive the right to any jury trial in any action, proceeding, or counterclaim brought by any party
