We
request that, by countersigning this Letter, you confirm your agreement to amend the definition of “Consolidated Liquidity”
and the terms of Clauses 12.4 and 12.5 of the Loan Agreement, presently providing as follows:

““Consolidated

by the Borrower on a freely available and unencumbered basis;”

|“12.4 | Minimum
    interest coverage. Commencing with the third fiscal quarter of 2011, the Borrower shall maintain a ratio of Consolidated
    EBITDA to Consolidated Net Interest Expense of not less than 2.50 to 1.00. Such ratio shall be calculated quarterly on a trailing
    quarter basis from and including the third fiscal quarter of 2011, provided that for the third fiscal quarter of 2012
    and all periods thereafter such ratio shall be calculated on a trailing four quarter basis.”
|----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------













|“12.5 | Free
    liquidity. From and after the Effective Date, the Borrower shall maintain Consolidated Liquidity, including all amounts
    on deposit with any Lead Arranger, of not less than $15,000,000 until the Borrower owns directly or indirectly a fleet of

    Liquidity, including all amounts on deposit with any Lead Arranger, of not less than $15,000,000 plus $750,000 per each additional
    vessel that the Borrower directly or indirectly owns over 15 vessels.”
