            Chairman, Chief Executive Officer and Chief Financial Officer

        


   

  

  Dear Mr. Panagiotidis:

   

  This agreement (the “Agreement”) constitutes the agreement between Maxim Group LLC (the “Placement Agent”) and Castor
    Maritime Inc., a company incorporated under the laws of the Republic of the Marshall Islands (the “Company”), pursuant to which the Placement Agent shall serve as the exclusive placement agent for the Company, on
    a “reasonable best efforts” basis, in connection with the proposed placement (the “Placement”) of a to be determined number of registered common share of the Company, par value $0.001 per share (the “Common Shares”, with the Common Shares offered in the Placement being referred to as the “Shares”) and (ii) unregistered warrants, each entitling the holder thereof to purchase
    one Common Share (the “Warrants”, and collectively with the Shares, the “Securities”).  The terms of the Placement and the Securities shall be mutually agreed upon by the
    Company and the purchasers (each, a “Purchaser” and collectively, the “Purchasers”) and nothing herein constitutes that the Placement Agent would have the power or
    authority to bind the Company or any Purchaser or an obligation for the Company to issue any Securities or complete the Placement.  This Agreement and the documents executed and delivered by the Company and the Purchasers in connection with the
    Placement, including but not limited to the Purchase Agreement (as defined below), the form of Warrant and this Agreement shall be collectively referred to herein as the “Transaction Documents.”  The date of the closing of the Placement shall be referred to herein as the “Closing Date.”  The Company expressly acknowledges and agrees that the Placement Agent’s obligations hereunder are on a reasonable best efforts basis only and that the execution of this Agreement does not constitute a
    commitment by the Placement Agent to purchase the Securities and does not ensure the successful placement of the Securities or any portion thereof or the success of the Placement Agent with respect to securing any other financing on behalf of the
    Company. Following the prior written consent of the Company, the Placement Agent may retain other brokers or dealers to act as sub-agents or selected-dealers on its behalf in connection with the Placement.  The sale of the Securities to any Purchaser
    will be evidenced by a securities purchase agreement (the “Purchase Agreement”) between the Company and such Purchaser in a form reasonably acceptable to the Company and
    the Placement Agent.  Capitalized terms that are not otherwise defined herein have the meanings given to such terms in the Purchase Agreement.  Prior to the signing of any Purchase Agreement, officers of the Company will be available to answer
    inquiries from prospective Purchasers.

   

  SECTION 1.        REPRESENTATIONS AND WARRANTIES OF THE COMPANY; COVENANTS OF THE COMPANY.

  

  

   A.          Representations of the Company.  Each of the representations and warranties (together with any related disclosure schedules thereto) and covenants made by the Company to the
    Purchasers in the Purchase Agreement in connection with the Placement is hereby incorporated herein by reference into this Agreement (as though fully restated herein) and is, as of the date of this Agreement and as of the Closing Date, hereby made to,
    and in favor of, the Placement Agent. In addition to the foregoing, the Company represents and warrants that:

  
    1

    
      


  

  

  

  

  

     1.          The Company has prepared and filed with the Commission a registration statement on Form F-3 (Registration No. 333-232052), and amendments thereto, and related preliminary prospectuses,
    for the registration under the Securities Act of 1933, as amended (the “Securities Act”), of the Securities, which registration statement, as so amended (including post-effective amendments, if any) became
    effective on June 21, 2019.  At the time of such filing, the Company met the requirements of Form F-3 under the Securities Act. Such registration statement meets the requirements set forth in Rule 415(a)(1)(x) under the Securities Act and complies with
    said Rule. The Company will file with the Commission pursuant to Rule 424(b) under the Securities Act, and the rules and regulations (the “Rules and Regulations”) of the Commission promulgated thereunder, a
    supplement to the form of prospectus included in such registration statement relating to the placement of the Securities and the plan of distribution thereof and has advised the Placement Agent of all further information (financial and other) with
    respect to the Company required to be set forth therein. Such registration statement, including the exhibits thereto, as amended at the date of this Agreement, is hereinafter called the “Registration Statement”;
    such prospectus in the form in which it appears in the Registration Statement is hereinafter called the “Base Prospectus”; and the supplemented form of prospectus, in the form in which it will be filed with the
    Commission pursuant to Rule 424(b) (including the Base Prospectus as so supplemented) is hereinafter called the “Prospectus Supplement.” Any reference in this Agreement to the Registration Statement, the Base
    Prospectus or the Prospectus Supplement shall be deemed to refer to and include the documents incorporated by reference therein (the “Incorporated Documents”) pursuant to Item 6 of Form F-3 which were filed under
    the Exchange Act on or before the date of this Agreement, or the issue date of the Base Prospectus or the Prospectus Supplement, as the case may be; and any reference in this Agreement to the terms “amend,” “amendment” or “supplement” with respect to
    the Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the filing of any document under the Exchange Act after the date of this Agreement, or the issue date of the Base Prospectus or the
    Prospectus Supplement, as the case may be, deemed to be incorporated therein by reference. All references in this Agreement to financial statements and schedules and other information which is “contained,” “included,” “described,” “referenced,” “set
    forth” or “stated” in the Registration Statement, the Base Prospectus or the Prospectus Supplement (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is
    or is deemed to be incorporated by reference in the Registration Statement, the Base Prospectus or the Prospectus Supplement, as the case may be. No stop order suspending the effectiveness of the Registration Statement or the use of the Base Prospectus
    or the Prospectus Supplement has been issued, and no proceeding for any such purpose is pending or has been initiated or, to the Company's knowledge, is threatened by the Commission. For purposes of this Agreement, “free



      writing prospectus” has the meaning set forth in Rule 405 under the Securities Act and the “Time of Sale Prospectus” means the preliminary prospectus, if any, together with the free writing prospectuses,
    if any, used in connection with the Placement, including any documents incorporated by reference therein.

   

     2.          The Registration Statement (and any further documents to be filed with the Commission) contains all exhibits and schedules as required by the Securities Act. Each of the Registration
    Statement and any post-effective amendment thereto, at the time it became effective, complied in all material respects with the Securities Act and the Exchange Act and the applicable Rules and Regulations and did not and, as amended or supplemented, if
    applicable, will not, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Base Prospectus, the Time of Sale Prospectus and the
    Prospectus Supplement, each as of its respective date, comply in all material respects with the Securities Act and the Exchange Act and the applicable Rules and Regulations. Each of the Base Prospectus, the Time of Sale Prospectus and the Prospectus
    Supplement, as amended or supplemented, did not and will not contain as of the date thereof any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances
    under which they were made, not misleading. The Incorporated Documents, when they were filed with the Commission, conformed in all material

  
    2

    
      


  

  

  

  

  

  respects to the requirements of the Exchange Act and the applicable Rules and Regulations, and none of such documents, when they were filed with the Commission, contained any untrue statement of a material fact or
    omitted to state a material fact necessary to make the statements therein (with respect to Incorporated Documents incorporated by reference in the Base Prospectus or Prospectus Supplement), in the light of the circumstances under which they were made
    not misleading; and any further documents so filed and incorporated by reference in the Base Prospectus, the Time of Sale Prospectus or Prospectus Supplement, when such documents are filed with the Commission, will conform in all material respects to
    the requirements of the Exchange Act and the applicable Rules and Regulations, as applicable, and will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the
    circumstances under which they were made, not misleading. No post-effective amendment to the Registration Statement reflecting any facts or events arising after the date thereof which represent, individually or in the aggregate, a fundamental change in
    the information set forth therein is required to be filed with the Commission. There are no documents required to be filed with the Commission in connection with the transaction contemplated hereby that (x) have not been filed as required pursuant to
    the Securities Act or (y) will not be filed within the requisite time period. There are no contracts or other documents required to be described in the Base Prospectus, the Time of Sale Prospectus or Prospectus Supplement, or to be filed as exhibits or
    schedules to the Registration Statement, which (x) have not been described or filed as required or (y) will not be filed within the requisite time period.

  

  

     3.          The Company is eligible to use free writing prospectuses in connection with the Placement pursuant to Rules 164 and 433 under the Securities Act. Any free writing prospectus that the
    Company is required to file pursuant to Rule 433(d) under the Securities Act has been, or will be, filed with the Commission in accordance with the requirements of the Securities Act and the applicable rules and regulations of the Commission
    thereunder. Each free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or that was prepared by or behalf of or used by the Company complies or will comply in all material respects
    with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder. The Company will not, without the prior consent of the Placement Agent, prepare, use or refer to, any free writing prospectus.

  

  

     4.          There are no affiliations with any FINRA member firm among the Company's officers, directors or, to the knowledge of the Company, any five percent (5.0%) or greater stockholder of the
    Company, except as set forth in the Registration Statement and SEC Reports.

  

  

   B.          Covenants of the Company. The Company has delivered, or will as promptly as practicable deliver, to the Placement Agent complete conformed copies of the Registration Statement and
    of each consent and certificate of experts, as applicable, filed as a part thereof, and conformed copies of the Registration Statement (without exhibits), the Base Prospectus, the Time of Sale Prospectus and the Prospectus Supplement, as amended or
    supplemented, in such quantities and at such places as the Placement Agent reasonably requests. Neither the Company nor any of its directors and officers has distributed and none of them will distribute, prior to the Closing Date, any offering material
    in connection with the offering and sale of the Securities pursuant to the Placement other than the Base Prospectus, the Time of Sale Prospectus, the Prospectus Supplement, the Registration Statement, copies of the documents incorporated by reference
    therein and any other materials permitted by the Securities Act.

   

  SECTION 2.       REPRESENTATIONS OF THE PLACEMENT AGENT. The Placement Agent  represents and warrants that it (i) is a member in good standing of FINRA, (ii) is registered as a
    broker/dealer under the Exchange Act, (iii) is licensed as a broker/dealer under the laws of the States applicable to the offers and sales of the Securities by such Placement Agent, (iv) is and will be a body corporate validly existing under the laws
    of its place of incorporation, and (v) has full power and authority to enter into and perform its obligations under this Agreement.  The Placement Agent will immediately

  

  

  
    3

    
      


  

  

  

  notify the Company in writing of any change in its status as such. The Placement Agent covenants that it will use its reasonable best efforts to conduct the Placement hereunder in compliance with the provisions of this
    Agreement and the requirements of applicable law.  

   

  SECTION 3.      COMPENSATION.  In consideration of the services to be provided for hereunder, the Company shall pay to the Placement Agent or their respective designees their pro rata
    portion (based on the Securities placed) of the following compensation with respect to the Securities which they are placing:

  

  

   A.          A cash fee (the “Cash Fee”) equal to an aggregate of seven and one-half percent (7.5%) of the aggregate gross proceeds raised in the Placement.  The
    Cash Fee shall be paid at the Closing of the Placement.

  

  

   B.         Subject to compliance with FINRA Rule 5110(f)(2)(D), the Company also agrees, in case of Closing of the Placement, to reimburse the Placement Agent for all travel and other out-of-pocket
    expenses, including the reasonable fees, costs and disbursements of its legal counsel, in an amount not to exceed an aggregate of $50,000.00. The Company will reimburse Placement Agent directly out of the Closing of the Placement.

  

  

   C.          The Placement Agent reserves the right to reduce any item of its compensation or adjust the terms thereof as specified herein in the event that a determination shall be made by FINRA to
    the effect that such Placement Agent’s aggregate compensation is in excess of FINRA Rules or that the terms thereof require adjustment.

   

  SECTION 4.      INDEMNIFICATION. The Company agrees to the indemnification and other agreements set forth in the Indemnification Provisions (the “Indemnification”)



    attached hereto as Addendum A, the provisions of which are incorporated herein by reference and shall survive the termination or expiration of this Agreement.

   

  SECTION 5.      ENGAGEMENT TERM. The Placement Agent’s engagement hereunder shall be until the earlier of (i) the final closing date of the Placement and (ii) the date a party terminates
    the engagement according to the terms of the next sentence (such date, the “Termination Date” and the period of time during which this Agreement remains in effect is referred to herein as the “Term”).  Notwithstanding anything to the contrary contained herein, the provisions concerning confidentiality, indemnification and contribution contained herein and the Company’s obligations contained in the
    Indemnification Provisions will survive any expiration or termination of this Agreement. The Placement Agent each agree, severally and not jointly, not to use any confidential information concerning the Company provided to the Placement Agent by the
    Company for any purposes other than those contemplated under this Agreement.

   

  

  SECTION 6.      PLACEMENT AGENT INFORMATION. The Company agrees that any information or advice rendered by the Placement Agent in connection with this engagement is for the confidential
    use of the Company only in their evaluation of the Placement and, except as otherwise required by law, the Company will not disclose or otherwise refer to the advice or information in any manner without the Placement Agent’s prior written consent.

   

  SECTION 7.       NO FIDUCIARY RELATIONSHIP. This Agreement does not create, and shall not be construed as creating rights enforceable by any person or entity not a party hereto, except
    those entitled hereto by virtue of the Indemnification Provisions hereof. The Company acknowledges and agrees that the Placement Agent is not and shall not be construed as a fiduciary of the Company and shall have no duties or liabilities to the equity
    holders or the creditors of the Company or any other person by virtue of

  
    4

    
      


  

  

  

  

  

  

  

  this Agreement or the retention of such Placement Agent hereunder, all of which are hereby expressly waived.

  

  

  SECTION 8.       CLOSING. The obligations of the Placement Agent, and the closing of the sale of the Securities hereunder are subject to the accuracy, when made and on the Closing
    Date, of the representations and warranties on the part of the Company and its Subsidiaries contained herein and in the Purchase Agreement, to the accuracy of the statements of the Company and its Subsidiaries made in any certificates pursuant to the

    by the Company:

   

   A.          No stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose shall have been initiated or threatened by the
    Commission, and any request for additional information on the part of the Commission (to be included in the Registration Statement, the Base Prospectus, the Prospectus Supplement or otherwise) shall have been complied with to the reasonable
    satisfaction of the Placement Agent. Any filings required to be made by the Company in connection with the Placement shall have been timely filed with the Commission.

  

  

   B.          The Placement Agent shall not have discovered and disclosed to the Company on or prior to the Closing Date that the Registration Statement, the Base Prospectus, the Prospectus Supplement
    or any amendment or supplement thereto contains an untrue statement of a fact which, in the opinion of counsel for the Placement Agent, is material or omits to state any fact which, in the opinion of such counsel, is material and is required to be
    stated therein or is necessary to make the statements therein not misleading.

  

  

   C.          All corporate proceedings and other legal matters incident to the authorization, form, execution, delivery and validity of each of this Agreement, the Securities, the Registration
    Statement, the Base Prospectus and the Prospectus Supplement and all other legal matters relating to this Agreement and the transactions contemplated hereby shall be reasonably satisfactory in all material respects to counsel for the Placement Agent,
    and the Company shall have furnished to such counsel all documents and information that they may reasonably request to enable them to pass upon such matters.

  

  

   D.          The Placement Agent shall have received from outside counsel to the Company such counsel’s written opinions, addressed to the Placement Agent and the Purchasers and dated as of the Closing

   F.           On the Closing Date, Placement Agent shall have received a certificate of the chief financial officer of the Company, dated, as applicable, as of the date of such Closing, to the effect
    that, as of the date of this Agreement and as of the applicable date, the representations and warranties of the Company contained herein and in the Purchase Agreement were and are accurate in all material respects, except for such changes as are

   H.         Neither the Company nor any of its Subsidiaries (i) shall have sustained since the date of the latest audited financial statements included or incorporated by reference in the Registration
    Statement, the Base Prospectus and the Prospectus Supplement, any loss or interference with its business from fire, explosion, flood, terrorist act or other calamity, whether or not covered by insurance, or from any labor dispute or court or
    governmental action, order or decree, otherwise than as set forth in or contemplated by the Registration Statement, the Base Prospectus and the Prospectus Supplement, (ii) since such date there shall not have been any change in the capital stock or
    long-term debt of the Company or any of its Subsidiaries or any change, or any development involving a prospective change, in or affecting the business, general affairs, management, financial position, stockholders' equity, results of operations or
    prospects of the Company and its Subsidiaries, otherwise than as set forth in or contemplated by the Registration Statement, the Base Prospectus and the Prospectus Supplement, and (iii) since such date there shall not have been any new or renewed
    inquiries by the Commission, FINRA or any other regulatory body regarding the Company, the effect of which, in any such case described in clause (i), (ii) or (iii), is, in the judgment of the Placement Agent, so material and adverse as to make it
    impracticable or inadvisable to proceed with the sale or delivery of the Securities on the terms and in the manner contemplated by the Base Prospectus, Time of Sale Prospectus and Prospectus Supplement.

  

  

   I.          The Common Shares are registered under the Exchange Act and, as of the Closing Date, the Securities shall, as is required by such Trading Market or the Transaction Documents, be listed and
    admitted and authorized for trading on the Trading Market or other applicable U.S. national exchange and satisfactory evidence of such action shall have been provided to the Placement Agent. The Company shall have taken no action designed to, or likely
    to have the effect of terminating the registration of the Common Shares under the Exchange Act or delisting or suspending from trading the Common Shares from the Trading Market or other applicable U.S. national exchange, nor has the Company received
    any information suggesting that the Commission or the Trading Market or other U.S. applicable national exchange is contemplating terminating such registration or listing.

  

  

   J.           No action shall have been taken and no statute, rule, regulation or order shall have been enacted, adopted or issued by any governmental agency or body which would, as of the Closing
    Date, prevent the issuance or sale of the Securities or materially and adversely affect or potentially and adversely affect the business or operations of the Company; and no injunction, restraining order or order of any other nature by any federal or
    state court of competent jurisdiction shall have been issued as of the Closing Date which would prevent the issuance or sale of the Securities or materially and adversely affect or potentially and adversely affect the business or operations of the
    Company.

  

  

   K.          The Company shall have prepared and filed with the Commission a Form 6-K with respect to the Placement, including as an exhibit thereto this Agreement, the form of Purchase Agreement and
    the form of Warrant.

  

  

   L.          The Company shall have entered into a Purchase Agreement with each of the Purchasers and such agreements shall be in full force and effect and shall contain representations, warranties and
    covenants of the Company as agreed between the Company and the Purchasers.

  

  

   M.          FINRA shall have raised no objection to the fairness and reasonableness of the terms and arrangements of this Agreement. In addition, the Company shall, if requested by the Placement

  
    6

    
      


  

  

  

  

  

  Agent, make or authorize Placement Agent’s counsel to make on the Company’s behalf, any filing with the FINRA Corporate Financing Department pursuant to FINRA Rule 5110 with respect to the Placement and pay all filing
    fees required in connection therewith.

  

  

   N.          Prior to the Closing Date, the Company shall have furnished to the Placement Agent such further information, certificates and documents as the Placement Agent may reasonably request.

   

  If any of the conditions specified in this Section 8 shall not have been fulfilled when and as required by this Agreement, or if any of the certificates, opinions, written statements or letters
    furnished to the Placement Agent or to Placement Agent’s counsel pursuant to this Section 8 shall not be reasonably satisfactory in form and substance to the Placement Agent and to Placement Agent’s counsel, all obligations of the Placement Agent
    hereunder may be cancelled by the Placement Agent at, or at any time prior to, the consummation of the Closing. Notice of such cancellation shall be given to the Company in writing or orally. Any such oral notice shall be confirmed promptly thereafter
    in writing.

   

  SECTION 9.      WAIVER OF LOCK-UP.  Reference is made to that certain Underwriting Agreement, dated June 23, 2020, between the Company and the Placement Agent (the “Underwriting Agreement”).  Solely for purposes of accommodating the financing by the Company contemplated by this Agreement (and for no other financing), the Placement Agent hereby waives the restriction provided for
    in Section 4.20(a) of the Underwriting Agreement.

   

  SECTION 10.    GOVERNING LAW; AGENT FOR SERVICE OF PROCESS, ETC. This Agreement will be governed by, and construed in accordance with, the laws of the State of New York applicable to
    agreements made and to be performed entirely in such State, without regard to the conflicts of laws principles thereof. This Agreement may not be assigned by either party without the prior written consent of the other party. This Agreement shall be
    binding upon and inure to the benefit of the parties hereto, and their respective successors and permitted assigns. Any right to trial by jury with respect to any dispute arising under this Agreement or any transaction or conduct in connection herewith
    is waived. Any dispute arising under this Agreement may be brought into the courts of the State of New York or into the Federal Court located in New York, New York and, by execution and delivery of this Agreement, the Company hereby accepts for itself
    and in respect of its property, generally and unconditionally, the jurisdiction of aforesaid courts. Each party hereto hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by
    delivering a copy thereof via overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice
    thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. The Company agrees that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be
    conclusive and binding upon the Company and may be enforced in any other courts to the jurisdiction of which the Company is or may be subject, by suit upon such judgment.  If either party shall commence an action or proceeding to enforce any provisions
    of a Transaction Document, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its attorney's fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or
    proceeding.  In addition to and without limiting the foregoing, the Company has confirms that it has appointed Seward & Kissel LLP, One Battery Park Plaza, New York, New York 10004, as its authorized agent (the “Authorized



      Agent”) upon whom process may be served in any suit, action or proceeding arising out of or based upon the this Agreement or the Transaction Documents or the transactions contemplated herein which may be instituted in any New York federal or
    state court, by the Agent, the directors, officers, partners, employees and agents of the Agents and each affiliate of the Agent, and expressly accept the non-exclusive jurisdiction of any such court in respect of any such suit, action or proceeding.
    The Company hereby represents and warrants that the Authorized Agent has accepted such appointment and has agreed to act as said agent for service of process, and the Company agrees to take

  
    7

    
      


  

  

  

  

  

  

  

  any and all action, including the filing of any and all documents that may be necessary to continue such appointment in full force and effect as aforesaid. The Company hereby authorizes and directs the Authorized Agent
    to accept such service. Service of process upon the Authorized Agent shall be deemed, in every respect, effective service of process upon the Company. If the Authorized Agent shall cease to act as agent for service of process, the Company shall
    appoint, without unreasonable delay, another such agent in the United States, and notify you of such appointment. Notwithstanding the foregoing, any action arising out of or based upon this Agreement may be instituted by the Agent, the directors,
    officers, partners, employees and agents of the Agent and each respective affiliate of the Agent, in any court of competent jurisdiction in the Republic of the Marshall Islands.  This paragraph shall survive any termination of this Agreement, in whole
    or in part.

    

  SECTION 11.     ENTIRE AGREEMENT/MISC. This Agreement (including the attached Indemnification Provisions) embodies the entire agreement and understanding between the parties hereto, and
    supersedes all prior agreements and understandings, relating to the subject matter hereof. If any provision of this Agreement is determined to be invalid or unenforceable in any respect, such determination will not affect such provision in any other
    respect or any other provision of this Agreement, which will remain in full force and effect. This Agreement may not be amended or otherwise modified or waived except by an instrument in writing signed by both Placement Agent and the Company. The
    representations, warranties, agreements and covenants contained herein shall survive the closing of the Placement and delivery of the Securities. This Agreement may be executed in two or more counterparts, all of which when taken together shall be
    considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any
    signature is delivered by facsimile transmission or a .pdf format file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such
    facsimile or .pdf signature page were an original thereof.

   

  SECTION 12.    CONFIDENTIALITY.  The Placement Agent (i) will keep the Confidential Information (as such term is defined below) confidential and will not (except as
    required by applicable law or stock exchange requirement, regulation or legal process (“Legal Requirement”)), without the Company’s prior written consent, disclose to any person any Confidential Information, and
    (ii) will not use any Confidential Information other than in connection with the Placement.  The Placement Agent further agree, severally and not jointly, to disclose the Confidential Information only to its Representatives (as such term is defined
    below) who need to know the Confidential Information for the purpose of the Placement, and who are informed by the Placement Agent of the confidential nature of the Confidential Information. The term “Confidential
      Information” shall mean, all confidential, proprietary and non-public information (whether written, oral or electronic communications) furnished by the Company to a Placement Agent or its Representatives in connection with such Placement
    Agent’s evaluation of the Placement. The term “Confidential Information” will not, however, include information which (i) is or becomes publicly available other than as a result of a disclosure by a Placement Agent or its Representatives in violation

  ADDENDUM A

  INDEMNIFICATION PROVISIONS

   

  In connection with the engagement of Maxim Group LLC (the “Placement Agent”) by Castor Maritime Inc. (the “Company”) pursuant to a placement agency agreement dated as of the date hereof, between the
    Company and the Placement Agent, as it may be amended from time to time in writing (the “Agreement”), the Company hereby agrees as follows:

  

  

  1.          To the extent permitted by law, the Company will indemnify the Placement Agent and its affiliates, directors, officers, employees and controlling persons (within the meaning of Section 15
    of the Securities Act of 1933, as amended, or Section 20 of the Securities Exchange Act of 1934) against all losses, claims, damages, expenses and liabilities, as the same are incurred (including the reasonable fees and expenses of counsel), relating
    to or arising out of its activities hereunder or pursuant to the Agreement, except, with regard to the Placement Agent, to the extent that any losses, claims, damages, expenses or liabilities (or actions in respect thereof) are found in a final
    judgment (not subject to appeal) by a court of law to have resulted primarily and directly from the Placement Agent’s willful misconduct or gross negligence in performing the services described herein, as the case may be.

  

  

  2.          Promptly after receipt by the Placement Agent of notice of any claim or the commencement of any action or proceeding with respect to which the Placement Agent is entitled to indemnity
    hereunder, the Placement Agent will notify the Company in writing of such claim or of the commencement of such action or proceeding, and the Company will assume the defense of such action or proceeding and will employ counsel reasonably satisfactory to
    the Placement Agent and will pay the fees and expenses of such counsel. Notwithstanding the preceding sentence, the Placement Agent will be entitled to employ counsel separate from counsel for the Company and from any other party in such action if
    counsel for the Placement Agent reasonably determines that it would be inappropriate under the applicable rules of professional responsibility for the same counsel to represent both the Company and the Placement Agent. In such event, the reasonable
    fees and disbursements of no more than one such separate counsel will be paid by the Company. The Company will have the exclusive right to settle the claim or proceeding provided that the Company will not settle any such claim, action or proceeding
    without the prior written consent of the Placement Agent, which will not be unreasonably withheld.

  

  

  3.        The Company agrees to notify the Placement Agent promptly of the assertion against it or any other person of any claim or the commencement of any action or proceeding relating to a
    transaction contemplated by the Agreement.

  

  

  4.          If for any reason the foregoing indemnity is unavailable to the Placement Agent or insufficient to hold the Placement Agent harmless, then the Company shall contribute to the amount paid or
    payable by the Placement Agent, as the case may be, as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect not only the relative benefits received by the Company on the one hand, and the Placement
    Agent on the other, but also the relative fault of the Company on the one hand and the Placement Agent on the other that resulted in such losses, claims, damages or liabilities, as well as any relevant equitable considerations. The amounts paid or
    payable by a party in respect of losses, claims, damages and liabilities referred to above shall be deemed to include any legal or other fees and expenses incurred in defending any litigation, proceeding or other action or claim. Notwithstanding the
    provisions hereof, the Placement Agent’s share of the liability hereunder shall not be in excess of the amount of fees actually received, or to be received, by the Placement Agent under the Agreement (excluding any amounts received as reimbursement of
    expenses incurred by the Placement Agent).

  
    A-1

    
      


  

  
  

  

  

  

  5.          These Indemnification Provisions shall remain in full force and effect whether or not the transaction contemplated by the Agreement is completed and shall survive the termination of the
    Agreement, and shall be in addition to any liability that the Company might otherwise have to any indemnified party under the Agreement or otherwise.
