FOR VALUE RECEIVED, the undersigned Kingfish Holding Corporation, a Delaware corporation (the "Company"), promises to pay to the order of James K. Toomey ("Payee", and Payee and any subsequent permitted holder(s) of this amended and restated convertible promissory note (the "Note") being referred to collectively as "Holder"), at Holder's address set forth below (or by wire transfer to Holder's wire address set forth below) or at such other place as Holder may designate in writing pursuant to the notice provisions below, the principal sum of SIXTY THOUSAND DOLLARS ($60,000.00) (the "Principal Amount"), together with accrued and unpaid interest thereon, said principal and interest to be due and payable as stated below.

This Note is issued pursuant to the terms of that certain Convertible Promissory Note Purchase Agreement, dated as of dated as of February 10, 2015, as amended by theFirst Amendment and Restatement of Convertible Promissory Note Purchase Agreement, dated as of December 15, 2015, by and between the Company and the Payee (the "Purchase Agreement"). Capitalized terms used herein without definition shall have the meanings given to such terms in the Purchase Agreement. This Note amends, restates in its entirety, and supersedes the prior Convertible Promissory Note No. 10 issued under the Original Purchase Agreement.

1. Interest Rate. The Company promises to pay simple interest on the outstanding principal amount of this Note from December 19, 2014 (the date that the underlying loan was originally made by the Holder to the Company) until paid in full at the fixed rate of three and one-half percent (3.5%) per annum. Interest shall be calculated on a 365-day year basis and shall be due and payable as set forth below.

2. Maturity. Unless this Note has been previously converted in accordance with the terms of Section 5 hereof, all outstanding principal and accrued and unpaid interest on this Note, plus all fees, costs and expenses then due under this Note, become fully due and payable upon demand by the Holder (the date of any such demand, the "Maturity Date").

3. Payments. No principal amount of this Note or any accrued interest on the principal balance of this Note is due or payable until the Maturity Date. All amounts payable hereunder shall be made for the account of the Holder at the address referred to in Section 8 of this Note.

4. Prepayment. The Company may not prepay this Note prior to the Maturity Date without the consent of the Holder. Following the Maturity Date, the Company may prepay any part or all of any amount payable under this Note, including principal or interest or both, at any time or times without any premium or penalty whatsoever. Any and all prepayments shall be applied first to reimbursement of Holder for any costs or expenses incurred by Holder to enforce or collect amounts owed hereunder, then to repayment of any accrued and unpaid interest hereunder, and then to principal outstanding hereunder.

5. Optional Conversion of Note.

(a) Optional Conversion Rights. The outstanding principal balance of this Note shall be convertible, in whole or in part, at the option of the Holder at any time prior to the Maturity Date, into shares of common stock, par value $0.0001 per share, of the Company ("Common Stock"), at the then-Conversion Price (as defined in Section 5(e) below)(the "Optional Conversion Right"). To the extent that the Holder decides to exercise his or her Optional Conversion Right, then any unpaid interest on this Note shall be converted into Common Stock on the same terms as the principal of the Note.

(b) Exercise of Optional Conversion Right. The Optional Conversion Right may be exercised by the Holder, in whole but not in part, at any time, and from time to time prior to the Maturity Date, by the surrender and presentment of this Note accompanied by a duly executed Notice of Exercise in the form attached hereto (the "Exercise Notice"), presented to the Company, at its principal office or at such other place as the Company may designate by notice in writing to the Holder.

(c) Issuance of Certificates. As soon as practicable after full or partial conversion of this Convertible Note, the Company at its expense (including, without limitation, the payment by it of all taxes and governmental charges applicable to such conversion and issuance of Common Stock) shall cause to be issued to the Holder a certificate representing the total number of shares of Common Stock for which this Convertible Note is being converted (the "Conversion Shares"). This Convertible Note shall be deemed to have been converted, and the Conversion Shares acquired thereby shall be deemed issued, and the Holder shall be deemed to have become holders of record of such Conversion Shares, for all purposes, as of the close of business on the date that this Convertible Note and the duly executed and completed Conversion Notice, has been presented and surrendered to the Company in accordance with the provisions of Section 5(b) hereof, notwithstanding that the transfer books of the Company may then be closed.

(d) Covenants of Company. The Company shall take all action as may be necessary to assure that such Conversion Shares (and any other securities and property) may be issued and delivered as provided herein without violation of the Company's Certificate of Incorporation of bylaws, any applicable law or regulation, or any requirements of any domestic securities exchange or inter dealer quotation system upon which the Common Stock may be listed.

(e) Definitions. For purposes of this Note:

(i) The term "Conversion Price" shall be equal to the quotient of the Principal Amount plus all accrued and unpaid interest under this Note as of the date of such calculation divided by the Per Share Value.

(ii) The "Per Share Value" shall be $1.00 per share of Common Stock, subject to adjustment as provided in Section 5(f) hereof.

(iii) The term "Sale of the Company" shall mean (A) any consolidation or merger of the Company with or into any other corporation or other entity or person, or any other corporate reorganization, other than any such consolidation, merger or reorganization in which the shareholders of the Company immediately prior to such consolidation, merger or reorganization, continue to hold at least a majority of the voting power of the surviving entity in substantially the same proportions (or, if the surviving entity is a wholly owned subsidiary, its parent) immediately after such consolidation, merger or reorganization; (B) any transaction or series of related transactions to which the Company is a party in which in excess of 50% of the Company's voting power is transferred; provided, however, that a Sale of the Company shall not include any transaction or series of transactions principally for bona fide equity financing purposes in which cash is received by the Company or any successor or indebtedness of the Company is cancelled or converted or a combination thereof; or (C) a sale, lease, exclusive license or other disposition of all or substantially all of the assets of the Company.

(f) Anti-Dilution Provisions. The number and kind of securities and other property that may be acquired upon the conversion of this Note and the Conversion Price shall be subject to adjustment, from time to time, upon the happening of any of the following events:

(i) In the event that the Company shall declare, pay, or make any dividend upon its outstanding shares of Common Stock payable in Common Stock or shall effect a subdivision of the outstanding Common Stock into a greater number of shares of Common Stock, then the number of Conversion Shares that may thereafter be purchased upon the exercise of the rights represented hereby shall be increased in proportion to the increase in the number of outstanding shares of Common Stock through such dividend or subdivision, and the Per Share Value shall be decreased in such proportion. In case the Company shall at any time combine the outstanding shares of Common Stock into a smaller number of shares of Common Stock, the number of Conversion Shares that may thereafter be acquired upon the exercise of the rights represented hereby shall be decreased in proportion to the decrease through such combination and the Per Share Value shall be increased in such proportion.

(ii) In the event that the Company declares, pays, or makes any dividend or other distribution upon its outstanding shares of Common Stock payable in securities or other property (excluding cash dividends and dividends payable in shares of Common Stock, but including, without limitation, shares of any other class of the Company's stock or stock or other securities convertible into or exchangeable for shares of Common Stock or any other class of the Company's stock or other interests in the Company or its assets), a proportionate part of those securities or that other property shall be set aside by the Company and delivered to the Holder in the event that the Holder exercises his Optional Conversion Right with respect to this Note. The securities and other property then deliverable to the Holder upon the conversion of this Note shall be in the same ratio to the total securities and property set aside for the Holder as the number of Conversion Shares with respect to which this Note is then converted is to the total number of Conversion Shares that may be acquired pursuant to this Note at the time the securities or property were set aside for the Holder.

(g) Per Share Value Adjustments. Except as otherwise provided in this Section 5, upon any adjustment of the Per Share Value, the Holder shall be entitled to purchase, based upon the new Per Share Value, the number of shares of Common Stock, calculated to the nearest full share, obtained by: (i) multiplying the (A) number of Conversion Shares that may be acquired pursuant to this Note immediately prior to the adjustment of the Per Share Value by (B) the Per Share Value in effect immediately prior to its adjustment, and (ii) dividing the product so obtained in clause (i) by the new Per Share Value.

(h) Prior Notice of a Sale of the Company. Notwithstanding any provision of this Note to the contrary, in the event that the Company consummates a Sale of the Company prior to the conversion or repayment in full of this Note, the Company will give the Holder at least five days prior written notice of the anticipated closing date of such Sale of the Company.

6. Expenses. In the event of any failure of the Company to pay all amounts due upon a demand made pursuant to Section 2 of this Note, the Company shall pay all reasonable attorneys' fees and court costs incurred by Holder in enforcing and collecting this Note.

7. Waiver. The Company hereby waives demand, notice, presentment, protest and notice of dishonor.

8. Notices. Any notice or other communications to be given or that may be given pursuant to this Note shall be deemed to have been given: (x) three (3) calendar days after the deposit of such notice or communication in the United States Mail, registered or certified, return receipt requested, with proper postage affixed thereto; (y) on the first Business Day after depositing such notice of communication with Federal Express, Express Mail, or other expedited mail or package delivery service guaranteeing delivery no later than the next Business Day if next Business Day delivery service has been requested and paid for (or on such subsequent Business Day as such delivery service has been requested, guaranteed and paid for); or (z) upon delivery if hand delivered or telecopied to the appropriate address and person as provided on the signature page to the Purchase Agreement or to the person to whose attention the notice is to be given to the other parties in the manner hereinabove provided; provided, however, that any notice changing Holder's address or wire address shall be effective only upon receipt by the Company.

9. Governing Law.

(a) This Note shall in all respects be governed by and construed in accordance with the laws of the State of Florida, without giving effect to the principles of conflict of laws thereof.

(b) Any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereunder shall be brought solely in the courts of the State of Florida located in Hillsborough County, Florida, or, if it has or can acquire jurisdiction, in the United States District Court for the Middle District of Florida (Orlando or Tampa Division), and each of the parties hereto hereby consents to the exclusive jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and waives any objection to the venue or the convenience of forum of any such courts. 

10. Modification; Waiver. No amendment, modification, forbearance or waiver of any provision of this Note, and no consent with respect to any departure by the Company therefrom, shall be effective unless the same shall be in writing and signed by the Holder and the Company

11. Assignment. Neither the Company nor the Holder may assign or transfer this Note without the prior written consent of the other party (not to be unreasonably withheld) provided that, in no event shall this Note or any interest herein be transferable, in whole or in part, to any person or entity under circumstances that would be reasonably likely to violate or trigger a consent or other approval requirement under applicable laws, including but not limited to U.S. securities laws, the Foreign Corrupt Practices Act, FINSA, laws restricting money transfers and payments to persons or entities located in certain restricted countries, foreign nationals identified on any restricted list, and associated regulations as in existence at the time, and the laws and regulations of any other country. Any such written notice shall set forth in reasonable detail the identity of the new Holder(s) and the terms of transfer of this Note (including a release by the applicable Holder of any right to receive any payments hereunder) and the Company shall be obligated to register the transfer of this Note and make payments to any Holder hereunder only if the Company determines such transfer or payment is not restricted or prohibited by any such laws (and the due date of any such payment shall be extended by the length of time that any such legal restriction or prohibition exists). This Note shall inure to the benefit of Holder, its successors and assigns, and to any person to whom Holder may grant an interest in any of the indebtedness evidenced hereby in compliance with the foregoing restrictions, and shall be binding upon the Company and its successors and assigns.

13. Time of Essence. Time is of the essence of the payment and performance of this Note.

14. Miscellaneous. The Company and Holder have participated jointly in the negotiation and drafting of this Note.

No delay by Holder in enforcing its rights hereunder or otherwise, shall prejudice Holder's rights to enforce this Note. Neither Party to this Note will be liable to the other for any failure or delay in performance under this Note due to circumstances beyond its reasonable control including, without limitation, Acts of God, labor disruption, war, terrorist threat or government action, or lack of availability of wire transfer systems or other international or national systems; provided, that if either party is unable to perform its obligations under this Note for one of these reasons it shall give prompt written notice thereof to the other party and the time for performance, if any, shall be deemed to be extended for a period equal to the duration of the conditions preventing performance.
