The
Convertible Note (this “Note”) has been issued in accordance with exemptions from registration under the Securities
Act of 1933, as amended (the “Securities Act”) pursuant to a Merger Agreement, dated the date hereof (the “Merger
Agreement”), among John Keeler & Co., Inc., d/b/a Blue Star Foods, a Florida corporation (the “Maker”),
the Holder (as defined below), and the other Sellers signatories thereto, Coastal Pride Company, Inc., a South Carolina corporation,
and Coastal Pride Seafood, LLC, a Florida limited liability company and wholly-owned subsidiary of the Maker. This Note is one
of an issue of four (4) convertible notes (such notes, the “Other Convertible Notes”) issued pursuant to the
Merger Agreement. Capitalized terms not otherwise defined herein shall have the meanings ascribed to them in the Merger Agreement.


 


Section
1. Principal and Interest. FOR VALUE RECEIVED, the Maker promises to pay to the order of __________________, an individual
(the “Holder”), the principal sum of _____________________ ($______.00) together with interest on any outstanding
unpaid principal at the rate of four percent (4%) per annum (computed on the basis of a 365-day year and the actual days elapsed),
as reduced by the issuance of Conversion Shares described in Section 4 below. One-sixth (1/6) of the total principal amount hereunder
and all accrued interest thereon shall be payable quarterly commencing on the first day of August 26, 2021, subject to adjustment
as described in Section 7 below.


 


All
payments due hereunder shall be made in lawful money of the United States.


 


Section

Section
4. Conversion. At the election of the Holder given at any time after the first anniversary of the date of this Note and
prior to the end of the 36-month term of this Note and prior to payment in full of this Note, the principal amount of, together
with accrued interest on, this Note may be convertible, in whole or in part, into shares of common stock, par value $0.0001 per
share, of Blue Star Foods Corp., a Delaware corporation (“Blue Star”) and the parent of the Maker, (the “Common
Stock”) at the rate of one share for each $2.00 of principal and/or interest so converted (the “Conversion
Shares”). Upon delivery to the Maker of a completed Notice of Conversion, in the form attached hereto, Blue Star shall
issue and deliver to the Holder as promptly as practicable after receipt of such Notice of Conversion that number of Conversion
Shares for the portion of this Note converted in accordance with the foregoing. The Holder shall not have rights as a shareholder
of Blue Star with respect to unconverted portions of this Note. However, the Holder will have all the rights of a shareholder
of Blue Star with respect to the Conversion Shares when issued.


 


Section
5. Adjustment of Number of Shares Issuable Upon Conversion. In the event that Blue Star shall, after the date of issuance
of this Note: (i) pay a stock dividend or make a distribution in shares of its capital stock (whether shares of its Common Stock
or of capital stock of any other class); (ii) subdivide its outstanding shares of Common Stock; (iii) combine its outstanding
shares of Common Stock into a smaller number of shares; or (iv) issue by reclassification of its shares of Common Stock any shares
of capital stock of the Company, the number of shares issuable upon conversion of this Note shall be adjusted so that the Holder
shall be entitled to receive the number of shares of capital stock of the Company which the Holder would have owned immediately
following such action had this Note been converted immediately prior thereto, and the number of shares issuable upon conversion
of this Note shall thereafter be subject to further adjustment pursuant to this Section 5. An adjustment made pursuant to this
Section 5 shall become effective retroactively immediately after the record date in the case of a dividend or distribution and
shall become effective immediately upon the effective date in the case of a subdivision, combination or reclassification.


 


Section
6. Reservation of Shares. Blue Star shall reserve and keep available out of its authorized common stock that number of
shares equal the number of Conversion Shares issuable upon conversion of all outstanding amounts under this Note.


 


Section
7. Offset. The principal amount due under this Note shall be reduced, pro rata with the principal amounts due under the
Other Convertible Notes and the promissory note issued by the Maker to Walter Lubkin, Jr., dated even date herewith, by the amount
of Damages, if any, to the Purchaser Indemnified Parties under Sections 6.2 and 6.3 of the Merger Agreement.


 


Section
8. Leak-Out. During the period commencing on the Closing Date and ending on the one-year anniversary thereof, the Holder
may not lend, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract
to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly (each a “Transfer”),
any Conversion Shares, or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of
the economic consequences of ownership of any such shares, whether any such transaction is to be settled by delivery of securities,
in cash or otherwise. From and after the one-year anniversary of the Closing Date, the Holder may Transfer up to 25% of the aggregate
of the Consideration Shares received under the Purchase Agreement and the Conversion Shares held by the Holder, in each successive
six-month period.

or if an involuntary proceeding under the Bankruptcy Code or under any other federal or state bankruptcy or insolvency law is
