Stock Purchase Agreement

This Stock Purchase Agreement (this "Agreement") is made as of August 15, 2017, by and between MFP Partners, L.P., a Delaware limited partnership ("Buyer"), and RMB Capital Management LLC, on behalf of the entities listed on Exhibit A to this Agreement (collectively, "Seller").  Buyer and Seller are referred to from time to time in this Agreement individually as a "Party" and together as the "Parties."

Buyer has agreed to purchase from Seller, and Seller has agreed on behalf of the entities set forth on Exhibit A to this Agreement to sell to Buyer, 375,000 shares of common stock (the "Shares") of S&W Seed Company (the "Company").  The Shares that each Seller shall sell are set forth across from such Seller's name on Exhibit A to this Agreement.

In consideration of and upon the basis of the representations, warranties and agreements and subject to the terms and conditions set forth in this Agreement, the Parties agree as follows:

1.Purchase and Sale.  Upon the terms and subject to the conditions of this Agreement, Buyer hereby purchases from Seller, and Seller hereby sells to Buyer, all of the Shares for an aggregate purchase price of $1,200,000.00 US (the "Purchase Price"). The Purchase Price is owing as of the date hereof, but shall be payable upon written (including by e-mail) confirmation from Buyer's prime broker, Goldman Sachs & Co., or the Company's transfer agent, Transfer Online, that the transfer of all the Shares has been affected. As soon as practicable upon receipt of such confirmation, and in any event no later than the next business day, Buyer shall pay to Seller the Purchase Price by wire transfer of immediately available funds to one or more accounts designated in writing in advance by Seller.

2.Representations and Warranties of Seller.  Seller hereby represents and warrants to Buyer on the date hereof, as follows:

(a)Seller is authorized to consummate the transactions contemplated by this Agreement;

(b)Seller is authorized to enter into this Agreement; and

(c)upon completion of the transactions contemplated by this Agreement, Buyer will receive good and marketable title to the Shares, free and clear of any encumbrance, lien, claim, charge, security interest or other interests.

(d)neither Seller, its affiliates nor anyone acting on its behalf has offered or sold the Shares by means of any form of general advertising or general solicitation within the meaning of Rule 502(c) under the Securities Act of 1933, as amended;

(e)Seller acquired the Shares without a view to any public resale, subsequent distribution or other distribution thereof in violation of the Securities Act;

(f)Neither Seller, its affiliates nor anyone acting on its behalf is a party to any contract, agreement or understanding with any person that would give rise to any

brokerage commission or finder's fee in connection with the sale of the Shares to Buyer or consummation of the transactions contemplated by this Agreement.

(g)Seller has received and carefully reviewed the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2016, all subsequent public filings of the Company with the Securities and Exchange Commission, other publicly available information regarding the Company, and such other information that it and its advisers deem necessary to make its decision to enter into the transactions contemplated by this Agreement;

(h)Seller has evaluated the merits and risks of the transactions contemplated by this Agreement based exclusively on its own independent review and consultations with such investment, legal, tax, accounting and other advisers as it deemed necessary. Seller has made its own decision concerning the transactions contemplated by this Agreement without reliance on any representation or warranty of, or advice from, Buyer.

(i)Neither Buyer nor any of its affiliates, members, employees and agents (i) has been requested to or has provided Seller with any information or advice with respect to the Shares nor is such information or advice necessary or desired, or (ii) has made or makes any representation as to the Company.

(j)Seller acknowledges and understands that (i) Buyer possesses material nonpublic information regarding the Company not known to Seller that may impact the value of the Shares, including, without limitation, (x) information received by principals and employees of Buyer in their capacities as director, significant stockholders and/or affiliates of the Company, (y) information otherwise received from the Company on a confidential basis, and (z) information received on a privileged basis from the attorneys and financial advisers representing the Company and its Board of Directors (collectively, the "Information"), and that Buyer is unable to disclose the Information to Seller. Seller understands, based on its experience, the disadvantage to which Buyer is subject due to the disparity of information between Seller and Buyer. Notwithstanding such disparity, Seller has deemed it appropriate to enter into this Agreement and to consummate the transactions contemplated by this Agreement.

(k)Seller agrees that none of Buyer, its affiliates, principals, members, employees and agents shall have any liability to Seller, its affiliates, principals, stockholders, partners, employees, agents, grantors or beneficiaries, whatsoever due to or in connection with Buyer's non-disclosure of the Information, and Seller hereby irrevocably waives any claim that it might have based on the failure of Buyer to disclose the Information.

(l)Seller acknowledges that (i) Buyer is relying on Seller's representations, warranties, acknowledgments and agreements in this Agreement as a condition to proceeding with the transactions contemplated by this Agreement; and (ii) without such representations, warranties and agreements, Buyer would not enter into this Agreement or engage in the transactions contemplated by this Agreement.
