made, or knowledge it may have, prior to the date of this Agreement and will continue in full force and effect. 
 7.2 Costs.
Imperial Petroleum shall pay any and all sales, use and similar taxes arising out of the contributions, conveyances and deliveries to be made hereunder, and shall pay all documentary, filing, recording, transfer, deed, and conveyance taxes and fees
required in connection therewith. 
 7.3 Headings; References; Interpretation. All Article and Section headings in this Agreement
are for convenience only and shall not be deemed to control or affect the meaning or construction of any of the provisions hereof. The words “hereof,” “herein” and “hereunder” and words of similar import, when used in
this Agreement, shall refer to this Agreement as a whole and not to any particular provision of this Agreement. All references herein to Articles and Sections shall, unless the context requires a different construction, be deemed to be references to
the Articles and Sections of this Agreement, respectively. All personal pronouns used in this Agreement, whether used in the masculine, feminine or neuter gender, shall include all other genders, and the singular shall include the plural and vice
versa. The use herein of the word “including” following any general statement, term or matter shall not be construed to limit such statement, term or matter to the specific items or matters set forth immediately following such word or to
similar items or matters, whether or not non-limiting language (such as “without limitation,” “but not limited to,” or words of similar import) is used with reference thereto, but rather
shall be deemed to refer to all other items or matters that could reasonably fall within the broadest possible scope of such general statement, term or matter. 

7.4 Successors and Assigns. The Agreement shall be binding upon and inure to the benefit of the Parties and their respective
successors and assigns. 
 7.5 No Third Party Rights. The provisions of this Agreement are intended to bind the Parties as to
each other and are not intended to and do not create rights in any other person or confer upon any other person any benefits, rights or remedies and no person is or is intended to be a third party beneficiary of any of the provisions of this
Agreement.

constitute one agreement binding on the parties hereto.

 7.7 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York without giving effect to any choice of law rules or provisions (whether of the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than
the State of New York. Each of the parties hereto submits to the exclusive jurisdiction of the United States District Court for the Southern District of New York (or, if jurisdiction in that court is not available, then any state court located
within the Borough of Manhattan, City of New York) for any and all legal actions arising out of or in connection with this Agreement. 

7.8 Severability. If any of the provisions of this Agreement are held by any court of competent jurisdiction to contravene, or to
be invalid under, the laws of any governmental body having jurisdiction over the subject matter hereof, such contravention or invalidity shall not invalidate the entire Agreement. Instead, this Agreement shall be construed as if it did not contain
the particular provision or provisions held to be invalid, and an equitable adjustment shall be made and necessary provision added so as to give effect, as nearly as possible, to the intention of the Parties as expressed in this Agreement at the
time of execution of this Agreement. 
 7.9 Deed; Bill of Sale; Assignment. To the extent required and permitted by applicable
law, this Agreement shall also constitute a “deed,” “bill of sale” or “assignment” of the Vessel-Owning Subsidiary Shares.

the Parties hereto. 
 7.11 Integration. This Agreement and the instruments referenced herein supersede all previous
understandings or agreements among the Parties, whether oral or written, with respect to its subject matter hereof. This Agreement and such instruments contain the entire understanding of the Parties with respect to the subject matter hereof and
thereof. No understanding, representation, promise or agreement, whether oral or written, is intended to be or shall be included in or form part of this Agreement unless it is contained in a written amendment hereto executed by the Parties hereto
after the date of this Agreement.
