BORROWER AND GUARANTOR FURTHER EXPRESSLY AGREE THAT THE FOREGOING RELEASE AND WAIVER AGREEMENT IS INTENDED TO BE AS BROAD AND INCLUSIVE AS PERMITTED BY THE LAWS OF THE STATE OF FLORIDA.

12.        ARBITRATION.

(a)        Arbitration . The parties hereto agree, upon demand by any party, to submit to binding arbitration all claims, disputes and controversies between or among them (and their respective employees, officers, directors, attorneys, and other agents), whether in tort, contract or otherwise in any way arising out of or relating to (i) any credit subject hereto, or any of the Loan Documents, and their negotiation, execution, collateralization, administration, repayment, modification, extension, substitution, formation, inducement, enforcement, default or termination; or (ii) requests for additional credit.

(b)        Governing Rules . Any arbitration proceeding will (i) proceed in a location in Broward County, Florida selected by the American Arbitration Association (“AAA”); (ii) be governed by the Federal Arbitration Act (Title 9 of the United States Code), notwithstanding any conflicting choice of law provision in any of the documents between the parties; and (iii) be conducted by the AAA, or such other administrator as the parties shall mutually agree upon, in accordance with the AAA’s commercial dispute resolution procedures, unless the claim or counterclaim is at least $1,000,000.00 exclusive of claimed interest, arbitration fees and costs in which case the arbitration shall be conducted in accordance with the AAA’s optional procedures for large, complex commercial disputes (the commercial dispute resolution procedures or the optional procedures for large, complex commercial disputes to be referred to herein, as applicable, as the “Rules”). If there is any inconsistency between the terms hereof and the Rules, the terms and procedures set forth herein shall control. Any party who fails or refuses to submit to arbitration following a demand by any other party shall bear all costs and expenses incurred by such other party in compelling arbitration of any dispute. Nothing contained herein shall be deemed to be a waiver by any party that is a bank of the protections afforded to it under 12 U.S.C. §91 or any similar applicable state law.

(c)        No Waiver of Provisional Remedies, Self-Help and Foreclosure . The arbitration requirement does not limit the right of any party to (i) foreclose against real or personal property collateral; (ii) exercise self-help remedies relating to collateral or proceeds of collateral such as setoff or repossession; or (iii) obtain provisional or ancillary remedies such as replevin, injunctive relief, attachment or the appointment of a receiver, before during or after the pendency of any arbitration proceeding. This exclusion does not constitute a waiver of the right or obligation of any party to submit any dispute to arbitration or reference hereunder, including those arising from the exercise of the actions detailed in sections (i), (ii) and (iii) of this paragraph.

(d)        Arbitrator Qualifications and Powers . Any arbitration proceeding in which the amount in controversy is $5,000,000.00 or less will be decided by a single arbitrator selected according to the Rules, and who shall not render an award of greater than $5,000,000.00. Any dispute in which the amount in controversy exceeds $5,000,000.00 shall be decided by majority vote of a panel of three arbitrators; provided however, that all three arbitrators must actively participate in all hearings and deliberations. The arbitrator will be a neutral attorney licensed in the State of Florida or a neutral retired judge of the state or federal judiciary of Florida, in either case with a minimum of ten years experience in the substantive law applicable to the subject matter of the dispute to be arbitrated. The arbitrator will determine whether or not an issue is arbitratable and will give effect to the statutes of limitation in determining any claim. In any arbitration proceeding the arbitrator will decide (by documents only or with a hearing at the arbitrator's discretion) any pre-hearing motions which are similar to motions to dismiss for failure to state a claim or motions for summary adjudication. The arbitrator shall resolve all disputes in accordance with the substantive law of Florida and may grant any remedy or relief that a court of such state could order or grant within the scope hereof and such ancillary relief as is necessary to make effective any award. The arbitrator shall also have the power to award recovery of all costs and fees, to impose sanctions and to take such other action as the arbitrator deems necessary to the same extent a judge could pursuant to the Federal Rules of Civil Procedure, the Florida Rules of Civil Procedure or other applicable law. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction. The institution and maintenance of an action for judicial relief or pursuit of a provisional or ancillary remedy shall not constitute a waiver of the right of any party, including the plaintiff, to submit the controversy or claim to arbitration if any other party contests such action for judicial relief.

(e)        Discovery . In any arbitration proceeding, discovery will be permitted in accordance with the Rules. All discovery shall be expressly limited to matters directly relevant to the dispute being arbitrated and must be completed no later than 20 days before the hearing date. Any requests for an extension of the discovery periods, or any discovery disputes, will be subject to final determination by the arbitrator upon a showing that the request for discovery is essential for the party's presentation and that no alternative means for obtaining information is available.

(f)        Class Proceedings and Consolidations . No party hereto shall be entitled to join or consolidate disputes by or against others in any arbitration, except parties who have executed any Loan Document, or to include in any arbitration any dispute as a representative or member of a class, or to act in any arbitration in the interest of the general public or in a private attorney general capacity.

(g)        Payment Of Arbitration Costs And Fees . The arbitrator shall award all costs and expenses of the arbitration proceeding.

(h)        Miscellaneous . To the maximum extent practicable, the AAA, the arbitrators and the parties shall take all action required to conclude any arbitration proceeding within 180 days of the filing of the dispute with the AAA. No arbitrator or other party to an arbitration proceeding may disclose the existence, content or results thereof, except for disclosures of information by a party required in the ordinary course of its business or by applicable law or regulation. If more than one agreement for arbitration by or between the parties potentially applies to a dispute, the arbitration provision most directly related to the Loan Documents or the subject matter of the dispute shall control. This arbitration provision shall survive termination, amendment or expiration of any of the Loan Documents or any relationship between the parties.

13.        Waiver of Bankruptcy Stay. BORROWER AND GUARANTOR HEREBY AGREE, IN CONSIDERATION OF THE RECITALS AND MUTUAL COVENANTS CONTAINED HEREIN, AND FOR OTHER GOOD AND VALUABLE CONSIDERATION, THE RECEIPT AND SUFFICIENCY OF WHICH ARE HEREBY ACKNOWLEDGED, THAT IN THE EVENT THAT BORROWER OR GUARANTOR SHALL FILE WITH ANY BANKRUPTCY COURT OF COMPETENT JURISDICTION OR BE THE SUBJECT OF ANY PETITION UNDER TITLE 11 OF THE UNITED STATES CODE THE AUTOMATIC STAY IMPOSED BY SECTION 362 OF TITLE 11 OF THE UNITED STATES CODE IS WAIVED, AND SUCH WAIVER CONSTITUTES “CAUSE” PURSUANT TO 11 U.S.C. SECTION 362(d)(1) FOR THE IMMEDIATE LIFTING OF THE AUTOMATIC STAY IN FAVOR OF BANK, AND BORROWER AND GUARANTOR HEREBY KNOWINGLY AND IRREVOCABLY WAIVE ALL DEFENSES AND OBJECTIONS TO SUCH LIFTING OF THE AUTOMATIC STAY.

8.       PAYMENT OF PREMIUMS, TAXES, CHARGES, LIENS AND ASSESSMENTS. Debtor agrees to pay, prior to delinquency, all insurance premiums, taxes, charges, liens and assessments against the Collateral and Proceeds, and upon the failure of Debtor to do so, Bank at its option may pay any of them and shall be the sole judge of the legality or validity thereof and the amount necessary to discharge the same. Any such payments made by Bank shall be obligations of Debtor to Bank, due and payable immediately upon demand, and at Bank’s option and subject to any restrictions under applicable law pertaining to usury, together with interest at a rate determined in accordance with the provisions of this Agreement, and shall be secured by the Collateral and Proceeds, subject to all terms and conditions of this Agreement.

9.       EVENTS OF DEFAULT. The occurrence of any of the following shall constitute an "Event of Default" under this Agreement: (a) an Event of Default under the Credit Agreement; (b) any representation or warranty made by Debtor herein shall prove to be incorrect, false or misleading in any material respect when made; (c) Debtor shall fail to observe or perform any obligation or agreement contained herein and with respect to any such default that by its nature can be cured, such default shall continue for a period of thirty (30) days from its occurrence, provided, however, if the default cannot by its nature be cured within the thirty (30) day period or cannot after diligent attempts by Debtor be cured within such thirty (30) day period, and such default is likely to be cured within a reasonable time, then Debtor shall have an additional period determined by Bank (which shall not in any case exceed an additional thirty (30) days) to attempt to cure such default, and within such reasonable time period the failure to cure the default shall not be deemed an Event of Default; (d) any impairment of the rights of Bank in any Collateral or Proceeds, or any attachment or like levy on any property of Debtor that causes a material adverse effect on the Debtor; and (e) Bank, in good faith, believes any or all of the Collateral and/or Proceeds to be in danger of misuse, dissipation, commingling, loss, theft, damage or destruction, or otherwise in jeopardy or unsatisfactory in character or value and such condition will have a material adverse effect on the rights of Bank hereunder.

10.       REMEDIES. Upon the occurrence of any Event of Default, Bank shall have the right to declare immediately due and payable all or any Indebtedness secured hereby and to terminate any commitments to make loans or otherwise extend credit to Debtor. Bank shall have all other rights, powers, privileges and remedies granted to a secured party upon default under the Uniform Commercial Code or the Business and Commerce Code of the jurisdiction identified in Section 18 below, or otherwise provided by law, including without limitation, the right (a) to contact all persons obligated to Debtor on any Collateral or Proceeds and to instruct such persons to deliver all Collateral and/or Proceeds directly to Bank, and (b) to sell, lease, license or otherwise dispose of any or all Collateral. In addition to any other remedies set forth in this Agreement, Debtor authorizes Bank to engage in “electronic self-help” as defined in and in accordance with applicable law. All rights, powers, privileges and remedies of Bank shall be cumulative. No delay, failure or discontinuance of Bank in exercising any right, power, privilege

or remedy hereunder shall affect or operate as a waiver of such right, power, privilege or remedy; nor shall any single or partial exercise of any such right, power, privilege or remedy preclude, waive or otherwise affect any other or further exercise thereof or the exercise of any other right, power, privilege or remedy. Any waiver, permit, consent or approval of any kind by Bank of any default hereunder, or any such waiver of any provisions or conditions hereof, must be in writing and shall be effective only to the extent set forth in writing. It is agreed that public or private sales or other dispositions, for cash or on credit, to a wholesaler or retailer or investor, or user of property of the types subject to this Agreement, or public auctions, are all commercially reasonable since differences in the prices generally realized in the different kinds of dispositions are ordinarily offset by the differences in the costs and credit risks of such dispositions. While an Event of Default exists: (a) Debtor will deliver to Bank from time to time, as requested by Bank, current lists of all Collateral and Proceeds; (b) Debtor will not dispose of any Collateral or Proceeds except on terms approved by Bank; (c) at Bank's request, Debtor will assemble and deliver all Collateral and Proceeds, and books and records pertaining thereto, to Bank at a reasonably convenient place designated by Bank; and (d) Bank may, without notice to Debtor, enter onto Debtor's premises and take possession of the Collateral. With respect to any sale or other disposition by Bank of any Collateral subject to this Agreement, Debtor hereby expressly grants to Bank the right to sell such Collateral using any or all of Debtor's trademarks, trade names, trade name rights and/or proprietary labels or marks. Debtor further agrees that Bank shall have no obligation to process or prepare any Collateral for sale or other disposition. In addition, Bank shall have the right to file against each individual government contract of Borrower, Guarantor and/or its subsidiaries, as applicable, in accordance with the terms of the Assignment of Claims Act of 1940, following and during the continuance of an Event of Default.

11.       DISPOSITION OF COLLATERAL AND PROCEEDS; TRANSFER OF INDEBTEDNESS. In disposing of Collateral hereunder, Bank may disclaim all warranties of title, possession, quiet enjoyment and the like. Any proceeds of any disposition of any Collateral or Proceeds, or any part thereof, may be applied by Bank to the payment of expenses incurred by Bank in connection with the foregoing, including reasonable attorneys' fees, and the balance of such proceeds may be applied by Bank toward the payment of the Indebtedness in such order of application as Bank may from time to time elect. Upon the transfer of all or any part of the Indebtedness, Bank may transfer all or any part of the Collateral or Proceeds and shall be fully discharged thereafter from all liability and responsibility with respect to any of the foregoing so transferred, and the transferee shall be vested with all rights and powers of Bank hereunder with respect to any of the foregoing so transferred; but with respect to any Collateral or Proceeds not so transferred, Bank shall retain all rights, powers, privileges and remedies herein given.

12.       STATUTE OF LIMITATIONS. Until all Indebtedness shall have been paid in full and all commitments by Bank to extend credit to Debtor have been terminated, the power of sale or other disposition and all other rights, powers, privileges and remedies granted to Bank hereunder shall, to the extent permitted by law, continue to exist and may be exercised by Bank at any time and from time to time irrespective of the fact that the Indebtedness or any part thereof may have become barred by any statute of limitations, or that the personal liability of Debtor may have ceased, unless such liability shall have ceased due to the payment in full of all Indebtedness secured hereunder.

13.       MISCELLANEOUS. When there is more than one Debtor named herein: (a) the word "Debtor" shall mean all or any one or more of them as the context requires; (b) the obligations of each Debtor hereunder are joint and several; and (c) until all Indebtedness shall have been paid in full, no Debtor shall have any right of subrogation or contribution, and each

Debtor hereby waives any benefit of or right to participate in any of the Collateral or Proceeds or any other security now or hereafter held by Bank. Debtor hereby waives any right to require Bank to (i) proceed against Debtor or any other person, (ii) marshal assets or proceed against or exhaust any security from Debtor or any other person, (iii) perform any obligation of Debtor with respect to any Collateral or Proceeds, and (iv) make any presentment or demand, or give any notices of any kind, including without limitation, any notice of nonpayment or nonperformance, protest, notice of protest, notice of dishonor, notice of intention to accelerate or notice of acceleration hereunder or in connection with any Collateral or Proceeds. Debtor further waives any right to direct the application of payments or security for any Indebtedness of Debtor or indebtedness of customers of Debtor.

14.       NOTICES. All notices, requests and demands required under this Agreement must be in writing, addressed to Bank at the address specified in any other loan documents entered into between Debtor and Bank and to Debtor at the address of its chief executive office (or principal residence, if applicable) specified below or to such other address as any party may designate by written notice to each other party, and shall be deemed to have been given or made as follows: (a) if personally delivered, upon delivery; (b) if sent by mail, upon the earlier of the date of receipt or three (3) days after deposit in the U.S. mail, first class and postage prepaid; and (c) if sent by telecopy, upon receipt.

15.       COSTS, EXPENSES AND ATTORNEYS' FEES. Debtor shall pay to Bank immediately upon demand the full amount of all payments, advances, charges, costs and expenses, including, to the extent permitted by applicable law, reasonable attorneys' fees (to include outside counsel fees), expended or incurred by Bank in connection with (a) the perfection and preservation of the Collateral or Bank's interest therein, and (b) the realization, enforcement and exercise of any right, power, privilege or remedy conferred by this Agreement, whether or not suit is brought or foreclosure is commenced, and where suit is brought, whether incurred at the trial or appellate level, in an arbitration proceeding or otherwise, and including any of the foregoing incurred in connection with any bankruptcy proceeding (including without limitation, any adversary proceeding, contested matter or motion brought by Bank or any other person) relating to Debtor or in any way affecting any of the Collateral or Bank's ability to exercise any of its rights or remedies with respect thereto. Notwithstanding anything in this Agreement to the contrary, reasonable attorneys’ fees shall not exceed the amount permitted by law. Whenever in this Agreement Debtor is obligated to pay for the attorneys' fees of Bank, or the phrase "reasonable attorneys' fees" or a similar phrase is used, it shall be Debtor's obligation to pay the attorneys' fees actually incurred or allocated, at standard hourly rates, without regard to any statutory interpretation, which shall not apply, Debtor hereby waiving the application of any such statute. Subject to any restrictions under applicable law pertaining to usury, all of the foregoing shall be paid by Debtor with interest from the date of demand until paid in full at a rate per annum equal to the greater of any default rate applicable to the Borrower’s outstanding obligations under the Credit Agreement, or Bank’s Prime Rate in effect from time to time.

16.       SUCCESSORS; ASSIGNS; AMENDMENT. This Agreement shall be binding upon and inure to the benefit of the administrators, legal representatives, successors and assigns of the parties, and may be amended or modified only in writing signed by Bank and Debtor.

17.       SEVERABILITY OF PROVISIONS. If any provision of this Agreement shall be held to be prohibited by or invalid under applicable law, such provision shall be ineffective only

to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or any remaining provisions of this Agreement.

18.       GOVERNING LAW. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, but giving effect to federal laws applicable to national banks.

19.       INSURANCE PROVISIONS.

CONTINUING GUARANTY

TO:      WELLS FARGO BANK, NATIONAL ASSOCIATION

1.       GUARANTY; DEFINITIONS. In consideration of any credit or other financial accommodation heretofore, now or hereafter extended or made to EnviroStar, Inc., a Delaware corporation ("Borrower"), by WELLS FARGO BANK, NATIONAL ASSOCIATION ("Bank"), and for other valuable consideration, the undersigned TRI-STATE TECHNICAL SERVICES, INC., a Delaware corporation ("Guarantor"), jointly and severally unconditionally guarantees and promises to pay to Bank, after the occurrence and during the continuance of an Event of Default (as such term is defined in the Credit Agreement dated as of October 7, 2016 between Borrower and Bank, as amended by that certain Amendment to Credit Agreement and Other Loan Documents dated as of June 23, 2017, as amended by that certain Second Amendment to Credit Agreement and Other Loan Documents dated of even date herewith (as the same may be further amended or modified from time to time, the “Credit Agreement”) in lawful money of the United States of America and in immediately available funds, any and all Indebtedness of any of the Borrower to Bank, all without relief from valuation and appraisement laws as applicable. The term "Indebtedness" is used herein in its most comprehensive sense and includes any and all advances, debts, obligations and liabilities of Borrower, heretofore, now or hereafter made, incurred or created, whether voluntary or involuntary and however arising, whether due or not due, absolute or contingent, liquidated or unliquidated, determined or undetermined, including under any swap, derivative, foreign exchange, hedge, deposit, treasury management or other similar transaction or arrangement, and whether the Borrower may be liable individually or jointly with others, or whether recovery upon such Indebtedness may be or hereafter becomes unenforceable. This Guaranty is a guaranty of payment and not collection. Guarantor’s obligations under this Guaranty are secured by that certain Security Agreement dated of even date herewith from Borrower, Guarantor and certain other entities in favor of Bank.

2.       MAXIMUM LIABILITY; SUCCESSIVE TRANSACTIONS; REVOCATION; OBLIGATION UNDER OTHER GUARANTIES. This is a continuing guaranty and all rights, powers and remedies hereunder shall apply to all Indebtedness of the Borrower to Bank, whether now existing or hereafter arising, including that arising under successive transactions which shall either continue the Indebtedness, increase or decrease it, or from time to time create new Indebtedness after all or any prior Indebtedness has been satisfied, and notwithstanding the dissolution, liquidation or bankruptcy of the Borrower or Guarantor or any other event or proceeding affecting the Borrower or Guarantor. This Guaranty shall not apply to any new Indebtedness created after actual receipt by Bank of written notice of its revocation as to such new Indebtedness; provided however, that loans or advances made by Bank to the Borrower after revocation under commitments existing prior to receipt by Bank of such revocation, and extensions, renewals or modifications, of any kind, of Indebtedness incurred by the Borrower or committed by Bank prior to receipt by Bank of such revocation, shall not be considered new Indebtedness. Any such notice must be sent to Bank by registered U.S. mail, postage prepaid, addressed to its office at 333 SE 2 ^nd Avenue, 22 ^nd Floor, Miami, Florida 33131, or at such other address as Bank shall from time to time designate. Any payment by Guarantor shall not reduce Guarantor's maximum obligation hereunder unless written notice to that effect is actually received by Bank at or prior to the time of such payment. The obligations of Guarantor hereunder shall be in addition to any obligations of Guarantor under any other guaranties of any liabilities or obligations of the Borrower or any other persons heretofore or hereafter given to Bank unless said other guaranties are expressly modified or revoked in

writing; and this Guaranty shall not, unless expressly herein provided, affect or invalidate any such other guaranties.

3.       OBLIGATIONS JOINT AND SEVERAL; SEPARATE ACTIONS; WAIVER OF STATUTE OF LIMITATIONS; REINSTATEMENT OF LIABILITY. The obligations hereunder are joint and several and independent of the obligations of Borrower, and a separate action or actions may be brought and prosecuted against Guarantor whether action is brought against the Borrower or any other person, or whether the Borrower or any other person is joined in any such action or actions. Guarantor acknowledges that this Guaranty is absolute and unconditional, there are no conditions precedent to the effectiveness of this Guaranty, and this Guaranty is in full force and effect and is binding on Guarantor as of the date written below, regardless of whether Bank obtains collateral or any guaranties from others or takes any other action contemplated by Guarantor. To the extent permitted by applicable law, Guarantor waives the benefit of any statute of limitations affecting Guarantor's liability hereunder or the enforcement thereof, and Guarantor agrees that any payment of any Indebtedness or other act which shall toll any statute of limitations applicable thereto shall similarly operate to toll such statute of limitations applicable to Guarantor's liability hereunder. The liability of Guarantor hereunder shall be reinstated and revived and the rights of Bank shall continue if and to the extent for any reason any amount at any time paid on account of any Indebtedness guaranteed hereby is rescinded or must otherwise be restored by Bank, whether as a result of any proceedings in bankruptcy or reorganization or otherwise, all as though such amount had not been paid. The determination as to whether any amount so paid must be rescinded or restored shall be made by Bank in its sole discretion; provided however, that if Bank chooses to contest any such matter at the request of Guarantor, Guarantor agrees to indemnify and hold Bank harmless from and against all costs and expenses, including reasonable attorneys' fees, expended or incurred by Bank in connection therewith, including without limitation, in any litigation with respect thereto.

4.       AUTHORIZATIONS TO BANK. Guarantor authorizes Bank either before or after revocation hereof, without notice to or demand on Guarantor, and without affecting Guarantor's liability hereunder, from time to time to: (a) alter, compromise, renew, extend, accelerate or otherwise change the time for payment of, or otherwise change the terms of the Indebtedness or any portion thereof, including increase or decrease of the rate of interest thereon; (b) take and hold security for the payment of this Guaranty or the Indebtedness or any portion thereof, and exchange, enforce, waive, subordinate or release any such security; (c) apply such security and direct the order or manner of sale thereof, including without limitation, a non-judicial sale permitted by the terms of the controlling security agreement, mortgage or deed of trust, as Bank in its discretion may determine; (d) release or substitute any one or more of the endorsers or any other guarantors of the Indebtedness, or any portion thereof, or any other party thereto; and (e) apply payments received by Bank from the Borrower to any Indebtedness of the Borrower to Bank, in such order as Bank shall determine in its sole discretion, whether or not such Indebtedness is covered by this Guaranty, and Guarantor hereby waives any provision of law regarding application of payments which specifies otherwise. Bank may without notice assign this Guaranty in whole or in part. Upon Bank's request, Guarantor agrees to provide to Bank copies of Guarantor's financial statements.

5.       REPRESENTATIONS, WARRANTIES AND COVENANTS. Guarantor represents and warrants to Bank that: (a) this Guaranty is executed at Borrower’s request; (b) Guarantor shall not, without Bank's prior written consent, sell, lease, assign, encumber, hypothecate, transfer or otherwise dispose of all or a substantial or material part of Guarantor's assets other than in the ordinary course of Guarantor's business; (c) Bank has made no

representation to Guarantor as to the creditworthiness of the Borrower; and (d) Guarantor has established adequate means of obtaining from the Borrower on a continuing basis financial and other information pertaining to Borrower’s financial condition. Guarantor agrees to keep adequately informed from such means of any facts, events or circumstances which might in any way affect Guarantor's risks hereunder, and Guarantor further agrees that Bank shall have no obligation to disclose to Guarantor any information or material about the Borrower which is acquired by Bank in any manner. In addition, Guarantor hereby covenants and agrees to comply with all covenants applicable to Guarantor as set forth in the Credit Agreement dated of even date herewith between Borrower and Bank.

6.       BANK'S RIGHTS WITH RESPECT TO GUARANTOR'S PROPERTY IN BANK'S POSSESSION. In addition to all liens upon and rights of setoff against the monies, securities or other property of Guarantor given to Bank by law, Bank shall have a lien upon and a right of setoff against all monies, securities and other property of Guarantor now or hereafter in the possession of or on deposit with Bank, whether held in a general or special account or deposit or for safekeeping or otherwise, and every such lien and right of setoff may be exercised without demand upon or notice to Guarantor. No lien or right of setoff shall be deemed to have been waived by any act or conduct on the part of Bank, or by any neglect to exercise such right of setoff or to enforce such lien, or by any delay in so doing, and every right of setoff and lien shall continue in full force and effect until such right of setoff or lien is specifically waived or released by Bank in writing. Bank may exercise this remedy regardless of the adequacy of any collateral for the obligations of Guarantor to Bank and whether or not the Bank is otherwise fully secured.

7.       SUBORDINATION. Any Indebtedness of the Borrower now or hereafter held by Guarantor is hereby subordinated to the Indebtedness of Borrower to Bank. For purposes of this Section 7, “Indebtedness” shall not include Borrower’s obligations owed to Guarantor related to regularly scheduled lease or rental obligations to its shareholders pursuant to bona fide written leases (copies of which have been provided to Bank), ordinary compensation to its shareholders (which compensation does not constitute indebtedness), share issuances to its shareholders, post-closing adjustments to the purchase price owed to Guarantor under that certain asset purchase agreement entered into by Borrower, Guarantor and certain other parties thereto, and buyer and seller indemnifications under said asset purchase agreement. Such Indebtedness of Borrower to Guarantor is assigned to Bank as security for this Guaranty and the Indebtedness and, if Bank requests, shall be collected and received by Guarantor as trustee for Bank and paid over to Bank on account of the Indebtedness of Borrower to Bank but without reducing or affecting in any manner the liability of Guarantor under the other provisions of this Guaranty. Any notes or other instruments now or hereafter evidencing such Indebtedness of the Borrower to Guarantor shall be marked with a legend that the same are subject to this Guaranty and, if Bank so requests, shall be delivered to Bank. Bank is hereby authorized in the name of Guarantor from time to time to file financing statements and continuation statements and execute such other documents and take such other action as Bank deems necessary or appropriate to perfect, preserve and enforce its rights hereunder.

8.       REMEDIES; NO WAIVER. All rights, powers and remedies of Bank hereunder are cumulative. No delay, failure or discontinuance of Bank in exercising any right, power or remedy hereunder shall affect or operate as a waiver of such right, power or remedy; nor shall any single or partial exercise of any such right, power or remedy preclude, waive or otherwise affect any other or further exercise thereof or the exercise of any other right, power or remedy. Any waiver, permit, consent or approval of any kind by Bank of any breach of this Guaranty, or any such waiver of any provisions or conditions hereof, must be in writing and shall be effective only to the extent set forth in writing.

9.       COSTS, EXPENSES AND ATTORNEYS' FEES. Guarantor shall pay to Bank immediately upon demand the full amount of all payments, advances, charges, costs and expenses, including, to the extent permitted by applicable law, reasonable attorneys' fees (to include outside counsel fees), expended or incurred by Bank in connection with the enforcement of any of Bank’s rights, powers or remedies and/or the collection of any amounts which become due to Bank under this Guaranty, and the prosecution or defense of any action in any way related to this Guaranty, whether or not suit is brought, and if suit is brought, whether incurred at the trial or appellate level, in an arbitration proceeding or otherwise, and including any of the foregoing incurred in connection with any bankruptcy proceeding (including without limitation, any adversary proceeding, contested matter or motion brought by Bank or any other person) relating to Guarantor or any other person or entity, Notwithstanding anything in this Guaranty to the contrary, reasonable attorneys’ fees shall not exceed the maximum amount permitted by law. Whenever in this Guaranty Guarantor is obligated to pay for the attorneys’ fees of Bank, or the phrase “reasonable attorneys’ fees” or a similar phrase is used, it shall be Guarantor’s obligation to pay the attorneys’ fees actually incurred or allocated, at standard hourly rates, without regard to any statutory interpretation, which shall not apply, Guarantor hereby waiving the application of any such statute.

16.       ARBITRATION.

(a)        Arbitration . The parties hereto agree, upon demand by any party, to submit to binding arbitration all claims, disputes and controversies between or among them (and their respective employees, officers, directors, attorneys, and other agents), whether in tort, contract or otherwise in any way arising out of or relating to this Guaranty and its negotiation, execution, collateralization, administration, repayment, modification, extension, substitution, formation, inducement, enforcement, default or termination. In the event of a court ordered arbitration, the party requesting arbitration shall be responsible for timely filing the demand for arbitration and paying the appropriate filing fee within 30 days of the abatement order or the time specified by the court. Failure to timely file the demand for arbitration as ordered by the court will result in that party’s right to demand arbitration being automatically terminated.

(b)        Governing Rules . Any arbitration proceeding will (i) proceed in a location in New York selected by the American Arbitration Association (“AAA”); (ii) be governed by the Federal Arbitration Act (Title 9 of the United States Code), notwithstanding any conflicting choice of law provision in any of the documents between the parties; and (iii) be conducted by the AAA, or such other administrator as the parties shall mutually agree upon, in accordance with the AAA’s commercial dispute resolution procedures, unless the claim or counterclaim is at least $1,000,000.00 exclusive of claimed interest, arbitration fees and costs in which case the arbitration shall be conducted in accordance with the AAA’s optional procedures for large, complex commercial disputes (the commercial dispute resolution procedures or the optional procedures for large, complex commercial disputes to be referred to herein, as applicable, as the “Rules”). If there is any inconsistency between the terms hereof and the Rules, the terms and procedures set forth herein shall control. Any party who fails or refuses to submit to arbitration following a demand by any other party shall bear all costs and expenses incurred by such other party in compelling arbitration of any dispute. Nothing contained herein shall be deemed to be a waiver by any party that is a bank of the protections afforded to it under 12 U.S.C. §91 or any similar applicable state law.

(c)        No Waiver of Provisional Remedies, Self-Help and Foreclosure . The arbitration requirement does not limit the right of any party to (i) foreclose against real or personal property

collateral; (ii) exercise self-help remedies relating to collateral or proceeds of collateral such as setoff or repossession; or (iii) obtain provisional or ancillary remedies such as replevin, injunctive relief, attachment or the appointment of a receiver, before during or after the pendency of any arbitration proceeding. This exclusion does not constitute a waiver of the right or obligation of any party to submit any dispute to arbitration or reference hereunder, including those arising from the exercise of the actions detailed in sections (i), (ii) and (iii) of this paragraph.

(d)        Arbitrator Qualifications and Powers . Any arbitration proceeding in which the amount in controversy is $5,000,000.00 or less will be decided by a single arbitrator selected according to the Rules, and who shall not render an award of greater than $5,000,000.00. Any dispute in which the amount in controversy exceeds $5,000,000.00 shall be decided by majority vote of a panel of three arbitrators; provided however, that all three arbitrators must actively participate in all hearings and deliberations. The arbitrator will be a neutral attorney licensed in New York or a neutral retired judge of the state or federal judiciary of New York, in either case with a minimum of ten years’ experience in the substantive law applicable to the subject matter of the dispute to be arbitrated. The arbitrator will determine whether or not an issue is arbitratable and will give effect to the statutes of limitation in determining any claim. In any arbitration proceeding the arbitrator will decide (by documents only or with a hearing at the arbitrator's discretion) any pre-hearing motions which are similar to motions to dismiss for failure to state a claim or motions for summary adjudication. The arbitrator shall resolve all disputes in accordance with the substantive law of New York and may grant any remedy or relief that a court of such state could order or grant within the scope hereof and such ancillary relief as is necessary to make effective any award. The arbitrator shall also have the power to award recovery of all costs and fees, to impose sanctions and to take such other action as the arbitrator deems necessary to the same extent a judge could pursuant to the Federal Rules of Civil Procedure, the corresponding rules of civil practice and procedure in New York or other applicable law. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction. The institution and maintenance of an action for judicial relief or pursuit of a provisional or ancillary remedy shall not constitute a waiver of the right of any party, including the plaintiff, to submit the controversy or claim to arbitration if any other party contests such action for judicial relief.

(e)        Discovery . In any arbitration proceeding, discovery will be permitted in accordance with the Rules. All discovery shall be expressly limited to matters directly relevant to the dispute being arbitrated and must be completed no later than 20 days before the hearing date. Any requests for an extension of the discovery periods, or any discovery disputes, will be subject to final determination by the arbitrator upon a showing that the request for discovery is essential for the party's presentation and that no alternative means for obtaining information is available.

(f)        Class Proceedings and Consolidations . No party hereto shall be entitled to join or consolidate disputes by or against others in any arbitration, except parties who have executed this Agreement or any other contract, instrument or document relating to any Indebtedness, or to include in any arbitration any dispute as a representative or member of a class, or to act in any arbitration in the interest of the general public or in a private attorney general capacity.

(g)        Payment Of Arbitration Costs And Fees . The arbitrator shall award all costs and expenses of the arbitration proceeding.

(h)        Miscellaneous . To the maximum extent practicable, the AAA, the arbitrators and the parties shall take all action required to conclude any arbitration proceeding within 180 days of

the filing of the dispute with the AAA or administrator. No arbitrator or other party to an arbitration proceeding may disclose the existence, content or results thereof, except for disclosures of information by a party required in the ordinary course of its business or by applicable law or regulation. If more than one agreement for arbitration by or between the parties potentially applies to a dispute, the arbitration provision most directly related to the documents between the parties or the subject matter of the dispute shall control. This arbitration provision shall survive termination, amendment or expiration of any of the documents or any relationship between the parties.

(i)        Small Claims Court . Notwithstanding anything herein to the contrary, each party retains the right to pursue in Small Claims Court any dispute within that court’s jurisdiction. Further, this arbitration provision shall apply only to disputes in which either party seeks to recover an amount of money (excluding attorneys’ fees and costs) that exceeds the jurisdictional limit of the Small Claims Court.

IN WITNESS WHEREOF, the undersigned Guarantor has executed this Guaranty, intending to be legally bound hereby, as of October 30, 2017.
