WHEREAS:

Buyer wishes to purchase from the Seller, and the Seller wishes to sell to Buyer, on the Closing Date (as defined below) upon the terms and conditions stated in this Agreement, an aggregate of three million three hundred ninety two thousand and eighty three (3,392,083) shares (the “Securities”) of the common stock, par value $0.01 per share (the “Common Shares”), of DORIAN LPG LTD., a company incorporated under the laws of the Republic of the Marshall Islands (the “Company”). The Securities represent approximately 5.842627 percent of the total issued and outstanding Common Shares of the Company.
