manner as it is described herein and Borrower will pay all costs of such filing. From time to time at the request of Secured Party, Borrower shall execute one or more financing statements and such other documents and do such other acts and things,
all as Secured Party may reasonably request, regarding the Security Interest in the Collateral. 
 (b) Secured
Party may examine and inspect the Collateral at any time, wherever located. 







 Section 4. Event of Default. The occurrence of any of the
following shall constitute an “Event of Default”: 
 (a) Borrower’s failure to make payment of any
principal, interest, fees, costs, charges, expenses, or other sums payable from time to time hereunder or under the Note when required hereunder or thereunder, and, in any such case, such failure shall continue for (i) in the case of a payment
of scheduled principal or interest, a period of five (5) business days following the date upon which any such payment was due, or (ii) in the case of any other amount payable, a period of five (5) business days following the date of
Borrower’s receipt from Secured Party of a written notice identifying the amount due and providing reasonable supporting details; 
 (b) Borrower shall cease operation of its present business; or 
 (c) Borrower
directly or indirectly sells, assigns, transfers, conveys, or suffers or permits to occur any sale, assignment, transfer or conveyance of all or substantially all of its assets, except as permitted herein. 

Section 5. Secured Party’s Rights and Remedies. Upon the occurrence of any Event of Default or at any time
thereafter: 
 (a) Secured Party may, at its option, declare all of the Indebtedness secured by this Agreement
(notwithstanding any provisions of any agreement with respect to the Indebtedness to the contrary) immediately due and payable without demand or notice of any kind, and the Indebtedness thereupon shall become due and payable immediately without
demand or notice (but with such adjustments, if any, with respect to interest or other charges as may be provided for in the promissory notes or other writings evidencing the Indebtedness secured). 

(b) Secured Party and its agents are authorized to enter into and enter onto any premises where the Collateral may be located for the
purpose of taking possession of the Collateral and any records thereof and Secured Party may, at its option, demand Borrower at Borrower’s expense to assemble the Collateral and make the Collateral available to Secured Party at a convenient
place acceptable to Secured Party and, after notice to the Borrower as hereinafter provided, and other reasonable notice to secured parties of record, Secured Party may sell or otherwise dispose of the Collateral at public or private sale, without
further notice or advertisement, at which sale Secured Party may become the purchaser. 
 (c) Secured Party may demand that
Borrower shall upon receipt by Borrower of any proceeds covered hereby or of any check, draft, or other instrument representing the proceeds, forthwith and without further notice or demand deliver the same to Secured Party in the form in which the
said items are received, endorsed by Borrower for payment to Secured Party. 
 (d) Secured Party may by written notice deem
Borrower to have transferred the Collateral to Secured Party and to have constituted and appointed Secured Party its true and lawful attorney-in-fact with full and irrevocable power and authority in the


  
 2 








 
name, place and stead of Borrower, from time to time, in Secured Party’s discretion to demand, collect, receive and give receipts for all monies due on the Collateral or due otherwise under
or with respect to any of the Collateral and to endorse any checks or other instruments or orders and to file any claims and take any other action or proceeding deemed by Secured Party appropriate for the purpose of collecting all such monies
whenever they may become payable. Secured Party may reasonably require Borrower to assist Secured Party in all such collections. 

(e) Secured Party shall have and may exercise, from time to time, all rights and remedies of a secured party under the Uniform Commercial
Code of Florida and all rights and remedies available to a secured party under any other applicable law. 
 (f) Any notice of
sale, disposition, or other intended action by Secured Party, mailed to Borrower at its business offices in Tampa, Florida or at any other address to which Borrower has requested in writing that notices be sent, at least five (5) days prior to
such action, shall constitute reasonable notice to Borrower. 
 (g) In the event of a sale or other disposition of the Collateral
or the receipt of any proceeds of the Collateral by Secured Party, after all of the Indebtedness with appropriate interest and all costs and expenses of Secured Party with respect to the possession and sale of the Collateral have been paid in full
as appropriate, the surplus, if any, shall be paid to Borrower by Secured Party, and any Collateral remaining shall be transferred and reassigned to Borrower by Secured Party; and in the event of a deficiency, there shall be due from Borrower and
Borrower shall immediately pay to Secured Party the difference between the amounts received by Secured Party and the remaining sum secured hereby, plus all costs and expenses of Secured Party in repossessing, transporting, repairing, storing,
selling or otherwise handling the Collateral pursuant to such sale or other disposition. 
 (h) All remedies hereunder shall be
cumulative and not alternative. Borrower shall pay promptly the costs and expenses of Secured Party of collection of all Indebtedness, enforcement of rights under this Agreement, including reasonable attorneys’ fees, and those costs, expenses,
and attorneys’ fees incurred in appellate proceedings and expenses and attorneys’ fees on any actions otherwise with respect to the Collateral 
 Section 6. Rights and Remedies of Borrower. Borrower shall have the rights and remedies provided in this Agreement and Borrower specifically waives and releases all rights provided in
Article 9 of the Uniform Commercial Code in force in the State of Illinois on the date of this Agreement. 

Section 7. Miscellaneous. 
 (a) Borrower authorizes Secured Party at Borrower’s expense to file any financing statement or statements relating to the Collateral (without Borrower’s signature thereon) which Secured Party
deems appropriate, and Borrower appoints Secured Party as Borrower’s attorney-in-fact to execute any such financing statement or statements in Borrower’s name and to perform all other acts which Secured Party deems appropriate to perfect
and to continue perfection of the Security Interest.

 (b) Without limiting any other right of Secured Party, whenever Secured
Party has the right to declare any Indebtedness to be immediately due and payable (whether or not it has so declared), Secured Party may set off against the Indebtedness all monies then owed to the Borrower by Secured Party in any capacity whether
due or not and Secured Party shall be deemed to have exercised its right to set off immediately at the time its right to such election accrues. 
 (c) Upon Borrower’s failure to perform any of its duties hereunder, Secured Party may but it shall not be obligated to perform any of such duties and Borrower shall forthwith upon demand reimburse
Secured Party for any expense incurred by Secured Party in so doing. 
 (d) No delay or omission by Secured Party
in exercising any right hereunder or with respect to any Indebtedness shall operate as a waiver of that or any other right, and no single or partial exercise of any right shall preclude Secured Party from any other or further exercise of any other
right or remedy. Secured Party may cure any default by Borrower in any reasonable manner without waiving the default so cured and without waiving any other prior or subsequent default by Borrower. 

(e) Secured Party shall have no obligation to take and Borrower shall have the sole responsibility for taking any steps to
preserve rights against all prior parties. Borrower waives presentment for payment, notice of protest, notice of nonpayment, notice of dishonor and protest of any instrument at any time held by Secured Party on which Borrower is in any way liable
and, if waivable, waives notice of any other action taken by Secured Party. 
 (f) The singular pronoun shall
include the plural, and the neuter shall include the masculine and feminine. 
 (g) This Agreement may not be
modified or amended nor shall any provision of it be waived except by a written instrument signed by Borrower and Secured Party. 
 (h) This Agreement is a continuing agreement and shall survive any closing and shall remain in force until Secured Party shall provide written notice of its termination and thereafter until all of the
Indebtedness contracted for or created before receipt of the notice and any extension or renewals of that Indebtedness (whether made before or after receipt of the notice) together with all interest thereon both before and after the notice, shall be
paid in full. 
 Section 8. Governing Law. This Agreement shall be governed by and construed in accordance
with the laws of Illinois, without reference to principles of choice or conflict of law thereunder. Whenever possible, each provision of this Agreement shall be interpreted to be effective and valid under applicable law. If any provision of this
Agreement is prohibited by or invalid under applicable law, the provision shall be ineffective only to the extent of the prohibition or invalidity, without invalidating the remainder of the provision or the other remaining provisions of this
Agreement.

 Section 9. Notice. All notices, requests, demands, claims, and other
communications hereunder shall be in writing and given in accordance with the notice provisions of the Note. 

Section 10. Jurisdiction. THE BORROWER HEREBY CONSENTS AND AGREES THAT THE STATE AND/OR FEDERAL COURTS LOCATED IN THE
STATE OF ILLINOIS SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN THE BORROWER, ON THE ONE HAND, AND THE SECURED PARTY, ON THE OTHER HAND, PERTAINING TO THIS AGREEMENT OR TO ANY MATTER ARISING OUT OF OR RELATED

JUDGMENT OR OTHER COURT ORDER IN FAVOR OF THE SECURED PARTY. THE BORROWER EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN ANY SUCH COURT, AND THE BORROWER HEREBY WAIVES ANY OBJECTION WHICH IT MAY
HAVE BASED UPON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE OR FORUM NON CONVENIENS. THE BORROWER AND THE SECURED PARTY HEREBY WAIVE PERSONAL SERVICE OF THE SUMMONS, COMPLAINT AND OTHER PROCESS ISSUED IN ANY SUCH ACTION OR SUIT AND AGREE
