	3.	CONTINUING GUARANTY 

 Each
Guarantor agrees that this Guaranty is a present and continuing guaranty of payment and not of collection and that each Guarantor’s obligations under this Guaranty is unconditional, irrespective of (i) the waiver or consent by Bank with

Guaranty. 
  

	4.	NO FRAUDULENT TRANSFER 

Notwithstanding any provision of this Guaranty to the contrary, it is intended that this Guaranty, and any Liens granted by each Guarantor
to secure the obligations and liabilities arising pursuant to this Guaranty, not constitute a “Fraudulent Transfer” (as defined below). Each Guarantor agrees that if this Guaranty, or any Liens securing the obligations and liabilities
arising pursuant to this Guaranty, would, but for the application of this sentence, constitute a Fraudulent Transfer, this Guaranty and each such Lien shall be valid and enforceable only to the maximum extent that would not cause this Guaranty or
such Lien to constitute a Fraudulent Transfer, and this Guaranty shall automatically be deemed to have been amended accordingly at all relevant times. For purposes hereof, “Fraudulent Transfer” means a fraudulent conveyance or fraudulent
transfer under §548 of the Bankruptcy Code or a fraudulent conveyance or fraudulent transfer under the provisions of any applicable fraudulent conveyance or fraudulent transfer law or similar law of any state, nation or other governmental unit,
as in effect from time to time. 

	5.	NO SUBROGATION 

 No payment made
by or for the account or benefit of any Guarantor, including, without limitation, (i) a payment made by Borrower in respect of the Guaranteed Obligations, (ii) a payment made by any other Guarantor pursuant to this Guaranty, (iii) a
payment made by any Person under any other guaranty of the Guaranteed Obligations or (iv) a payment made by means of set-off or other application of funds by Bank pursuant to this Guaranty shall entitle any Guarantor, by subrogation or
otherwise, to any payment by Borrower or from or out of any property of Borrower, and no Guarantor shall exercise any right or remedy against Borrower or any Property of Borrower including any right of contribution or reimbursement by reason of any
performance by any Guarantor under this Guaranty, until the Guaranteed Obligations have been indefeasibly satisfied and discharged in full by payment or performance and the Lien of the Security Agreement has been terminated. 

 

	6.	WAIVER 

 Each Guarantor hereby
waives diligence, presentment, demand of payment, filing of claims with a court in the event of any bankruptcy proceeding (or other insolvency proceeding) of Borrower, protest or notice with respect to the Guaranteed Obligations and all demands
whatsoever, and covenants that this Guaranty will not be discharged, except by complete and irrevocable payment and performance of the obligations and liabilities contained herein. Each Guarantor also waives all set-offs and counterclaims and all
presentments, demands for performance, notices of nonperformance, protests, notices of protest, notices of dishonor and notices of acceptance of this Guaranty. 
  

	7.	NOTICES; WAIVER OF NOTICE 

 All
notices, approvals, requests, demands and other communications under this Guaranty shall be given in accordance with the notice provisions of the Loan Agreement. No notice to any Guarantor or any other party shall be required for Bank to make demand
under this Guaranty. Such demand shall constitute a mature and liquidated claim against each Guarantor. Upon the occurrence and during the continuance of any Event of Default, Bank may, at its sole election, proceed directly and at once, without
notice, against any Guarantor to collect and recover the full amount or any portion of the Guaranteed Obligations, without first proceeding against Borrower, any other Guarantor, any other Person or any security or collateral for the Guaranteed
Obligations. Each Guarantor further waives all notices of the existence, creation or incurring of new or additional indebtedness, arising either from additional loans extended to Borrower or otherwise, and also waives all notices that the principal
amount, or any portion thereof, or any interest under or on any Loan Documents is due, notices of any and all Proceedings to collect from the maker, any endorser or any other guarantor of all or any part of the Guaranteed Obligations, or from anyone
else, and, to the extent permitted by law, notices of exchange, sale, surrender or other handling of any security or collateral given to Bank to secure payment of the Guaranteed Obligations. 

 

	8.	APPLICATION OF PAYMENTS 

 Bank
has the exclusive right to determine the application of payments and credits, if any, from any Guarantor, Borrower, any other Person, or any security or collateral for the Guaranteed Obligations, on account of the Guaranteed Obligations or of any
other liability of any Guarantor to Bank under this Guaranty. 

	9.	ACCELERATION, ETC. 

 Bank is
authorized, without notice or demand to any Guarantor and without affecting or impairing the liability of any Guarantor under this Guaranty, to, from time to time, (i) renew, extend, accelerate or otherwise change the time for payment of, or
other terms relating to, the Guaranteed Obligations or otherwise modify, amend or change the provisions of any of the Loan Documents, (ii) accept partial payments on the Guaranteed Obligations, (iii) take and hold collateral for the
payment of the Guaranteed Obligations, or for the payment of this Guaranty, or for the payment of any other guaranties of the Guaranteed Obligations or other liabilities of Borrower, and exchange, enforce, waive and release any such collateral,
(iv) apply such collateral and direct the order or manner of sale thereof as in their sole discretion they may determine and (v) settle, release, compromise, collect or otherwise liquidate the Guaranteed Obligations and any collateral
therefor in any manner. 
  

	10.	SET-OFF 

 At any time after
maturity of the Guaranteed Obligations, Bank may, in its sole discretion, without notice to any Guarantor and regardless of the acceptance of any collateral for the payment hereof, appropriate, set off, and apply toward payment of the Guaranteed
Obligations (i) any indebtedness due or to become due from Bank to any Guarantor, and (ii) any moneys, credits or other property belonging to any Guarantor at any time held by or coming into the possession of Bank or any affiliates
thereof, whether for deposit or otherwise. 
  

	11.	DISCLOSURE OF INFORMATION 

 Each
Guarantor assumes responsibility for keeping itself informed of the financial condition of Borrower, and any and all endorsers and other guarantors of all or any part of the Guaranteed Obligations and of all other circumstances bearing upon the risk
of nonpayment of the Guaranteed Obligations or any part thereof that diligent inquiry would reveal, and each Guarantor agrees that Bank has no duty to advise any Guarantor of information known to Bank regarding such condition or any such
circumstances. Each Guarantor acknowledges familiarity with Borrower’s financial condition and that it has not relied on any statements by Bank in obtaining such information. In the event Bank, in its sole discretion, undertakes at any time or
from time to time to provide any such information to any Guarantor, Bank is under no obligation (i) to undertake any investigation with respect thereto, (ii) to disclose any information which, pursuant to accepted or reasonable commercial
finance practices, Bank wishes to maintain confidential or (iii) to make any other or future disclosures of such information, or any other information, to such Guarantor. 

 

	12.	MARSHALLING OF ASSETS; RECEIPT OF CERTAIN PAYMENTS 

Each Guarantor consents and agrees that Bank is not under any obligation to marshal any assets in favor of any Guarantor or against or in
payment of any or all of the Guaranteed Obligations. Each Guarantor further agrees that, to the extent that Borrower makes a payment or payments to Bank, or Bank receives any proceeds of Collateral, which payment or payments or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to Borrower, its estate, trustee, receiver or any other party, including without limitation any Guarantor, under any bankruptcy law, state or
federal law, common law or equitable cause, then to the extent of such payment or repayment, the Guaranteed Obligations or the part thereof which has been paid, reduced or satisfied by such amount shall be reinstated and continued in full force and
effect as of the date such initial payment, reduction or satisfaction occurred, and this Guaranty shall continue to be in existence and in full force and effect, irrespective of whether any evidence of indebtedness has been surrendered or cancelled.

	13.	TERMINATION OF GUARANTY 

 Upon
payment in full of all Guaranteed Obligations and termination or expiration of the Loan under the Loan Agreement, the guaranties provided for under this Guaranty shall terminate and each Guarantor shall be released from this Guaranty. 

 

	14.	REPRESENTATIONS 

 Each Guarantor
represents and warrants to Bank that (i) it is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, and (ii) the execution, delivery and performance by such Guarantor of this
Guaranty and the other Loan Documents to which it is a party are within its powers, have been duly authorized by all necessary action pursuant to its articles or certificate of incorporation, bylaws, and other governing documents, require no further
action by or in respect of, or filing with, any governmental body, agency or official and do not violate, conflict with or cause a breach or a default under any provision of applicable law or regulation, its articles or certificate of incorporation,
bylaws, or other governing documents or any agreement, judgment, injunction, order, decree or other instrument binding upon it. Each Guarantor represents and warrants that this Guaranty, and each of the other Loan Documents to which it is a party,
constitutes the legal, valid, and binding agreement or instrument of that Guarantor, enforceable against that Guarantor in accordance with its provisions subject to bankruptcy, insolvency, fraudulent conveyance, or other similar statutes, rules,
regulations or other laws affecting the enforcement of creditor rights and remedies generally. In addition to and without limitation of the foregoing, each Guarantor confirms that it has reviewed the representations and warranties of that Guarantor
contained in the Loan Documents and agrees that such representations and warranties are deemed to have been made by such Guarantor in this Agreement and are fully incorporated into and made a part of this Guaranty by reference. 

 

	15.	NO DELAY 

 No delay on the part
of Bank in the exercise of any right or remedy operates as a waiver thereof, and no single or partial exercise by Bank of any right or remedy precludes any further exercise thereof, nor shall any modification or waiver of any provision of this
Guaranty be binding upon Bank, except as expressly set forth in a writing duly signed and delivered on Bank’s behalf by an authorized officer or agent of Bank. Bank’s failure at any time or times hereafter to require strict performance by
Borrower or any Guarantor of any of the provisions, warranties, terms and conditions contained in this Guaranty or any of the other Loan Documents does not waive, affect or diminish any right of Bank at any time or times thereafter to demand strict
performance thereof and such right shall not be deemed to have been waived by any act or knowledge of Bank, or its respective agents, officers or employees, unless such waiver is contained in an instrument in writing signed by an officer or agent of
Bank, and directed to Borrower or a Guarantor, as applicable, specifying such waiver. No failure or delay by Bank in exercising any right, power or privilege under this Guaranty operates as a waiver thereof nor does any single or partial exercise
thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies under this Agreement are cumulative and not exclusive of any rights or remedies provided by law. 

	16.	BINDING EFFECT 

 This Guaranty is
binding upon each Guarantor and their respective legal representatives, successors, and assigns and inures to the benefit of Bank and its successors and assigns, except that no Guarantor may assign its obligations under this Agreement without the
written consent of Bank. 
  

	17.	COUNTERPARTS 

 This Guaranty may
be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. 

 

	18.	SUBMISSION TO JURISDICTION; VENUE 

The validity, construction, enforcement and interpretation of this Agreement shall be governed by the substantive laws of the State of
Florida, without application of its conflicts of law principles, and the United States of America. Any action, suit or other Proceeding arising out of this Agreement shall be brought in the Thirteenth Judicial Circuit in and for Hillsborough County,
Florida, or in the United States District Court for the Middle District of Florida, Tampa Division, and each party irrevocably consents to and submits to the jurisdiction of those courts, and irrevocably waives any objection which such party now or
hereafter may have to the institution of any such suit, action or other Proceeding in those courts, and further irrevocably waives any defense or claim that such suit, action or other Proceeding in any such court has been brought in an inconvenient
forum or improper venue. 
  

	19.	WAIVER OF JURY TRIAL 

 Bank and
each Guarantor knowingly, voluntarily and intentionally waive any rights it may have to a trial by jury, with respect to any Proceeding based on or arising out of this Agreement, the Loan Agreement or any of the Loan Documents, including any course
of conduct, course of dealings, verbal or written statements or actions or omissions of any party which in any way relate to the Loan. The parties to this Agreement have specifically discussed and negotiated this waiver and understand the legal
consequences of signing this Agreement. This waiver by each Guarantor is a material inducement for Bank’s entering into the Loan Agreement, and Bank’s waiver is a material inducement for the execution and delivery by each of the Guarantors
of this Agreement, and the other Loan Documents to which such Guarantor is a party.

	4.	FINANCING STATEMENTS 

 Each Guarantor hereby
irrevocably authorizes Bank at any time and from time to time to file in any Uniform Commercial Code jurisdiction any initial financing statements and amendments thereto that (a) indicate the Collateral (i) as all assets or personal
property of each Guarantor or words of similar effect, regardless of whether any particular asset comprised in the Collateral falls within the scope of the Uniform Commercial Code or analogous provisions of such jurisdiction, or (ii) as being

any time a beneficiary under a letter of credit now or hereafter issued in favor of that Guarantor, that Guarantor shall promptly notify Bank thereof and, at the request and option of Bank, that Guarantor shall, pursuant to an agreement in form and
substance satisfactory to Bank, either (i) arrange for the issuer and any confirmer of such letter of credit to consent to an assignment to Bank of the proceeds of any drawing under the letter of credit or (ii) arrange for Bank to become

Bank to become the entitlement holder with respect to such investment property, with the Guarantor being permitted, only with the consent of Bank, to exercise rights to withdraw or otherwise deal with such investment property. Bank agrees with each
Guarantor that Bank shall not give any such entitlement orders or instructions or directions to any such issuer, securities intermediary or commodity intermediary, and shall not withhold its consent to the exercise of any withdrawal or dealing
rights by the Guarantor, unless an Event of Default has occurred and is continuing, or, after giving effect to any such investment and withdrawal rights not otherwise permitted by the Loan Documents, would occur. The provisions of this section shall
not apply to any financial assets credited to a securities account for which Bank is the securities intermediary. 
  

	7.	COLLATERAL IN THE POSSESSION OF A BAILEE 

 If any
goods comprising the Collateral are at any time in the possession of a bailee, that Guarantor shall promptly notify Bank thereof and, if requested by Bank, shall promptly obtain an acknowledgement from the bailee, in form and substance satisfactory
to Bank, that the bailee holds such Collateral for the benefit of Bank and shall act upon the instructions of Bank, without the further consent of the Guarantor. Bank agrees with each Guarantor that Bank shall not give any such instructions unless
an Event of Default has occurred and is continuing or would occur after taking into account any action by the Guarantor with respect to the bailee. 
  

	8.	ELECTRONIC CHATTEL PAPER AND TRANSFERABLE RECORDS 

If any Guarantor at any time holds or acquires an interest in any electronic chattel paper or any “transferable record,” as that term is defined
in §201 of the federal Electronic Signatures in Global and National Commerce Act, or in §16 of the Uniform Electronic Transactions Act as in effect in any relevant jurisdiction, that Guarantor shall promptly notify Bank thereof and, at the
request of Bank, shall take such action as Bank may reasonably request to vest in Bank control under §9-105 of the Florida Uniform Commercial Code of such electronic chattel paper or control under §201 of the federal Electronic Signatures

procedures satisfactory to Bank and so long as such procedures will not result in Bank’s loss of control, for each Guarantor to make alterations to the electronic chattel paper or transferable record permitted under §9-105 of the Florida
Uniform Commercial Code or, as the case may be, §201 of the federal Electronic Signatures in Global and National Commerce Act or §16 of the Uniform Electronic Transactions Act for a party in control to make without loss of control, unless
an Event of Default has occurred and is continuing or would occur after taking into account any action by the Guarantor with respect to such electronic chattel paper or transferable record. 

	9.	COMMERICAL TORT CLAIMS 

 If any Guarantor at any
time holds or acquires a commercial tort claim in excess of Twenty-five Thousand Dollars ($25,000.00), upon the filing of a complaint or counter-claim for such claim, that Guarantor shall promptly furnish to Bank copies of all pleadings made in
connection therewith, and shall grant to Bank in writing, a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and substance satisfactory to Bank. 

 

	10.	PROMISSORY NOTES AND TANGIBLE CHATTEL PAPER

	11.	SUBSIDIARIES 

 Each Guarantor agrees that it will

	15.	BANK’S RIGHTS AND REMEDIES 

 Bank, at any
time, either before or after an Event of Default, at the sole option of Bank, but without any obligation to do so, may discharge, satisfy, perform or cause to be discharged, satisfied or performed, for and on behalf of the Guarantors, any covenants,
representations, warranties or agreements contained in this Agreement which the Guarantors have failed or refuse to perform, and may pay for the repair, maintenance and preservation of any of the Collateral, including the payment of liens, taxes and
the purchase of insurance, and may do all other things deemed necessary or proper by Bank to perfect the lien and security interest granted by this Agreement, and to preserve, collect, enforce and protect the Collateral, and the proceeds of any
insurance insuring the Collateral, and all sums expended or obligations incurred therefor, including Attorneys’ Fees, court costs, agents’ fees or commissions, or any other costs or expenses incurred by Bank in connection therewith, shall
become part of the Secured Obligations, shall bear interest from the date of payment at the rate of eighteen percent (18%) per annum or, if less, the maximum contract rate of interest permitted to be charge by applicable law, and shall be
secured by this Agreement. 
  

	16.	GENERAL RIGHTS AND REMEDIES OF BANK 

 In addition
to all rights and remedies granted to Bank at law, in equity or by agreement, including this Agreement, Bank has and may exercise all rights and remedies afforded a secured party under the Uniform Commercial Code. 

	17.	PUBLIC OR PRIVATE SALE OF THE COLLATERAL 

 After
the occurrence of an Event of Default, Bank or its nominee, unless otherwise proscribed by law, after giving ten (10) days’ written notice to the Guarantors of intention to do so, may, from time to time, sell, assign and deliver the whole
or any part of the Collateral at any broker’s board or at any private sale or at public auction, with or without demand or advertisement of the time or place of sale or adjournment thereof or otherwise, for cash, for credit or for other
property, for immediate or future delivery, and for such price or prices and on such terms, and subject to such conditions and other provisions, as Bank in its sole discretion may determine. At any sale, Bank may bid for or purchase free from any
right or redemption on the part of the Guarantors (all said rights being hereby waived and released), with respect to any portion of or all the Collateral offered for sale and may make payment on account thereof by using any claim then due and
payable to Bank by the Guarantors as a credit against the purchase price, and Bank may, upon compliance with the terms of sale, hold, retain and dispose of such property without further accountability therefor. An agreement to sell all or any part
of the Collateral shall be treated as a sale thereof, and Bank shall be free to carry out such sale pursuant to such agreement, and the Guarantors shall not be entitled to the return of any Collateral subject thereto, notwithstanding that after Bank
shall have entered into such agreement, each Event of Default shall have been remedied or the Secured Obligations shall have been paid or otherwise satisfied or discharged in full. The Guarantors will execute and deliver such documents and take such
other action as Bank deems necessary or advisable in order that any such sale shall be made in compliance with law. 
 Each Guarantor agrees
that ten (10) days’ prior written notice of the time and place of any sale or other intended disposition of any of the Collateral constitutes reasonable notification before disposition of the Collateral for purposes of the Uniform
Commercial Code. The notice (if any) of such sale shall (i) in case of a public sale, state the time and place fixed for such sale, and (ii) in the case of a private sale, state the day after which such sale may be consummated. Any such
public sale shall be held at such time or times within ordinary business hours and at such place or places as Bank may fix in the notice of such sale. Bank shall not be obligated to make any such sale pursuant to any such notice. Bank may, without
notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for the sale, and such sale may be made at any time or place to which the same may be so
adjourned. 
 Upon any such sale Bank shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral
so sold. Each purchaser at any such sale shall hold the Collateral so sold to it absolutely and free from any claim or right of whatsoever kind of the Guarantors, including any equity or right of redemption of the Guarantors that may be waived, and
the Guarantors, to the extent permitted by law, specifically waive all rights of redemption, stay or appraisal which they have or may have under any law now existing or hereafter adopted. 

In case of any sale of all or part of the Collateral on credit or for future delivery, the Collateral so sold may be retained by Bank until the selling
price is paid by the purchaser, but Bank does not incur any liability in case of the failure of such purchaser to take up and pay for the Collateral so sold and, in case of any such failure, such Collateral may again be sold upon like notice.

 Each Guarantor hereby irrevocably consents to any act by Bank or its agents in entering upon any premises for the purpose of either:
(i) inspecting the Collateral or (ii) taking possession of the Collateral after any Event of Default, and each Guarantor hereby waives its right to assert against Bank or its agents any claim based upon trespass or any similar cause of
action for entering upon any premises where the Collateral may be located. 

 In connection with Bank’s exercise of any rights or remedies under this Agreement, Bank may—

 Require the Guarantors to assemble all records pertaining to the Collateral and make them available to Bank at a place to be designated by
Bank which is reasonably convenient to all parties. 
 Without charge, use or occupy the premises of the Guarantors or premises under any of the
Guarantor’s control. 
 Without charge, use any patent, trademark, trade name, or other intellectual property or technical process used by
the Guarantors in connection with any of the Collateral. 
 Rely conclusively upon the advice or instructions of any one or more brokers or
other experts selected by Bank to determine the method or manner of disposition of any of the Collateral and, in such event, any disposition of the Collateral by Bank in accordance with such advice or instructions is deemed to be commercially
reasonable. 
 Collect and apply all proceeds of the Collateral, may endorse the name of the Guarantors on any and all checks, drafts, money
orders, notes, acceptances or other instruments of the same or a different nature, constituting, evidencing or relating to the Collateral, and may receive and open all mail addressed to the Guarantors and remove therefrom any cash or noncash items
of payment constituting proceeds of the Collateral. 
 Adjust, settle, and cancel any and all insurance covering any Collateral, endorse the
name of the Guarantors on any and all checks or drafts drawn by any insurer, whether representing payment for a loss or a return of unearned premium, and execute any and all proofs of claim and other documents or instruments of every kind required
by any insurer in connection with any payment by such insurer. 
 Notify account debtors that their accounts have been assigned to Bank, and
that payments in respect of those accounts should be made directly to Bank. 
  

	18.	COSTS AND EXPENSES OF ENFORCEMENT 

 The
Guarantors shall pay all costs and expenses incurred by Bank in enforcing this Agreement, realizing upon any Collateral and collecting any of the Secured Obligations, including Attorneys’ Fees and costs, whether suit is brought or not, and the
Guarantors shall be liable for any deficiencies in the event the proceeds of disposition of the Collateral does not satisfy the Secured Obligations in full. 

	19.	BANK NOT LIABLE 

 All risk and liability for
safekeeping of the Collateral shall at all times, either before or after possession thereof by Bank, remain that of the Guarantors. Bank shall not be liable for any act or omission on the part of Bank, its officers, agents, representatives, or
employees, except for willful misconduct or gross negligence. Nothing contained in this Agreement shall be construed as requiring or obligating Bank to make any commitment or to make any inquiry as to the nature or sufficiency of any payment
received by Bank, or to present or file any claim or notice, or to take any action with respect to the Collateral or any part thereof or the monies due or to become due in respect thereof or any Property covered thereby. Nothing contained in this
Agreement relieves the Guarantors of any of their obligations under this Agreement or any of the other of the Loan Documents or imposes any obligation on Bank to proceed in any particular manner with respect to the Collateral or any part thereof, or
in any way limit the exercise by Bank of any other or further right which it may have under this Agreement, any of the other Loan Documents, any other agreement, by law or otherwise. 

 

	20.	INDEMNIFICATION 

 Each Guarantor shall indemnify
and hold Bank harmless from any and all claims, causes of action, or other proceedings, and from any and all liability, loss, damage and expense of every nature, arising by reason of Bank’s enforcement of its rights and remedies under this
Agreement, other than claims, causes of action, or other proceedings arising from the gross negligence or willful misconduct of Bank. As to any action taken by Bank under this Agreement, Bank shall not be liable for any error of judgment or mistake
of fact or law, absent gross negligence or willful misconduct on its part. 
  

	21.	CUMULATIVE AND CONCURRENT REMEDIES 

 Each and
every right and remedy given Bank, to the extent permitted by law, is cumulative and concurrent, and is in addition to any other right or remedy granted to Bank pursuant to this Agreement or now or hereafter existing at law or in equity, by statute
or by agreement, and the exercise or partial exercise of any such right or remedy does not preclude the exercise of any other right or remedy. 
  

	22.	APPLICATION OF PROCEEDS 

 Bank shall apply the
proceeds of any sale of the whole or any part of the Collateral, after first deducting all reasonable costs and expenses of collection, sale and delivery (including reasonable Attorneys’ Fees through all Proceedings) incurred by Bank in
connection with such sale, to the payment of all or any amounts due and payable in respect of the Secured Obligations and, upon payment in full of all such amounts, shall pay over any balance of such proceeds and other monies according to law, and
unless otherwise legally obligated, to the Guarantors. Bank shall account to the Guarantors for any surplus. If the proceeds are not sufficient to pay the Secured Obligations in full, each Guarantor shall remain liable for any deficiency.

	23.	RELEASE OF COLLATERAL 

 Upon payment, performance
or other satisfaction in full of the Secured Obligations, this Agreement shall terminate and each Guarantor shall be entitled to the return, at its expense, of such of the Collateral remaining in the possession of Bank as has not theretofore been
sold pursuant to this Agreement, together with any monies at the time held by Bank as Collateral under this Agreement. 
  

	24.	NO WAIVER 

 The failure of Bank to insist upon or
enforce strict performance of any provision of this Agreement or to exercise any right, power or authority under this Agreement or available at law, in equity or by agreement, or the single or partial exercise of any such right, power or authority,
shall not preclude any or further exercise thereof or the exercise of any other right, power or authority, or be construed as a waiver, renouncement or relinquishment to any extent of Bank’s right to assert or rely upon that provision, right,
power or authority in that or any other instance, and that provision, right, power or authority shall continue in full legal force and effect without waiver, renouncement or relinquishment. No waiver by Bank of any provision of this Agreement shall
be binding unless in writing and signed by Bank. No waiver by Bank of any provision of this Agreement shall be deemed or shall constitute a waiver of any other provision of this Agreement, whether or not similar, nor shall any waiver constitute a
continuing waiver, unless otherwise expressly provided. 
  

	25.	SEVERABILITY 

 Each paragraph, section,
provision, sentence and part thereof of this Agreement is severable from each other paragraph, section, provision, sentence or part thereof of this Agreement, and the invalidity or unenforceability of any such paragraph, section, provision, sentence
or part thereof, does not affect the validity or enforceability of the balance of this Agreement. In the event that any provision of this Agreement conflicts with the law under which this Agreement is to be construed or if any such provision is held
invalid by a court of competent jurisdiction, the parties to this Agreement intend that (i) such provision be deemed to be amended and restated to reflect as nearly as possible the original intentions of the parties in conformity with
applicable law, and (ii) the remaining terms, provisions, covenants and restrictions of this Agreement remain in full legal force and effect in accordance with their provisions. If any provision of this Agreement is held invalid or
unenforceable in any jurisdiction, such invalidity or unenforceability shall attach only to such provision in that jurisdiction and does not in any manner affect or render invalid or unenforceable that provision in any other jurisdiction or any
other provision of this Agreement in that or any other jurisdiction. 
  

	26.	AMENDMENT 

 Neither this Agreement nor any
provision of this Agreement may be changed, waived, discharged or terminated orally nor in any manner other than by an instrument in writing signed by the party against whom enforcement of the change, waiver, discharge or termination is sought.

	27.	GOVERNING LAW 

 The validity, construction,
enforcement and interpretation of this Agreement is to be governed by the substantive laws of the State of Florida, without application of its conflicts of law principles, and the Federal law of the United States of America, except to the extent
that the Florida Uniform Commercial Code requires the application of the law of another state. Any action, suit or proceeding arising out of this Agreement must be brought in the courts of the State of Florida, or in the United States courts located
within the State of Florida, and each party irrevocably consents to and submits to the jurisdiction of those courts for the purpose of any suit, action or proceeding arising out of this Agreement, and irrevocably waives any objection which such
party now or hereafter may have to the institution of any such suit, action or proceeding in a state or federal court located within the State of Florida, and further irrevocably waives any claim that such suit, action or proceeding in any such
court has been brought in an inconvenient forum. The parties further agree that for purposes of any State court proceeding, the Thirteenth Judicial Circuit in and for Hillsborough County, Florida, and for purposes of any federal court proceeding,
the United States District Court for the Middle District of Florida, Tampa Division, is the proper venue, and each party waives any defense or claim that such venue is an improper or inconvenient forum and consents to the personal jurisdiction of
such courts. 
  

	28.	WAIVER OF JURY TRIAL 

 Each party, as a condition
of its right to enforce or defend any right under or in connection with this Agreement, waives any right to a trial by jury and agrees that any action shall be tried before a court and not before a jury. 

 

	29.	CONSTRUCTION 

 Whenever the context so requires,
references in this Agreement to the singular shall include the plural, and the plural shall include the singular, and the masculine the feminine, the feminine the masculine, and the neuter both. There shall be no rule of construction for or against
any party by reason of the physical preparation of this Agreement.

third party beneficiary of this Agreement.
