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 Borrower 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 Borrower (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 Borrower 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 Borrower 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. Borrower
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.

Borrower 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
Borrower, including any equity or right of redemption of Borrower that may be waived, and Borrower, to the extent permitted by law, specifically waives all rights of redemption, stay or appraisal which it has 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.

Borrower 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 Borrower hereby waives Borrowers 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 Borrower 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 both parties.

Without charge, use or occupy the
premises of Borrower or premises under Borrowers control.



---

Without charge, use any patent, trademark, trade name, or other intellectual property or technical process
used by Borrower 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 Borrower 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 Borrower 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
Borrower 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
|--- | ---------------------------------

Borrower
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 Borrower 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 Borrower. 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
Borrower of any of its 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
|--- | ---------------

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.

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

unless otherwise legally obligated, to Borrower. Bank shall account to Borrower for any surplus. If the proceeds are not sufficient to pay the Secured Obligations in full, Borrower 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 Borrower 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.



|30. | THIRD-PARTY BENEFICIARY
|--- | -----------------------

Nothing contained in
this Agreement is to be construed so as to grant or confer on any Person other than Bank and Borrower, and their respective successors and permitted assigns, any rights or privileges under this Agreement, and no Person is intended to be a third
party beneficiary of this Agreement.



|31. | HEADINGS
|--- | --------
