REGISTERED
PURSUANT TO SECTION 12 OF THE

SECURITIES
EXCHANGE ACT OF 1934

 

The
following is a general description of the common stock of RespireRx Pharmaceuticals Inc. (the “Company”) and does
not purport to be complete. For a complete description of the terms and provisions of the common stock, refer to the Company’s
Second Restated Certificate of Incorporation, as amended to date (the “Certificate of Incorporation”) and By-Laws
of the Company, as amended (the “Bylaws”), each of which is an exhibit incorporated by reference into the Annual Report
on Form 10-K of which this exhibit is a part. This summary is qualified in its entirety by reference to these documents.

 

Authorized
and Outstanding Capital Stock

 

The
Company is authorized to issue a total of 70,000,000 shares of capital stock, with a par value of $0.001 per share. Of the authorized
amount, 65,000,000 of the shares are designated as common stock and 5,000,000 of the shares are designated as preferred stock.
The Company’s board of directors (the “Board”) and a majority of stockholders acting by written consent have
recently approved an amendment to the Certificate of Incorporation that would increase the number of authorized shares to 1,005,000,000,
with 1,000,000,000 of the shares designated as common stock and 5,000,000 of the shares designated as preferred stock. The Company
has circulated an Information Statement regarding these approvals and intends to file a certificate of amendment effecting such
increase on or about April 30, 2020, after the waiting period in connection with the Information Statement has run. The Company’s
common stock is registered under Section 12(g) of the Securities Exchange Act of 1934 (the “Act”). No other security
of the Company is registered under Section 12 of the Act.

 

As
of December 31, 2019, there were 4,175,072 shares of common stock issued and outstanding.

 

Description
of Common Stock

 

General.
Each share of the Company’s common stock has the same rights and privileges. Holders of the common stock do not have
any preferences or any preemptive, redemption, subscription, conversion or exchange rights. All outstanding shares of common stock
are fully paid and non-assessable. The Company’s common stock is quoted on the OTC QB, under the symbol “RSPI.”

 

Voting
Rights. The holders of common stock are entitled to vote upon all matters submitted to a vote of stockholders and are entitled
to one vote for each share of common stock held. There is no cumulative voting.

 

Dividends.
The Company has never paid cash dividends on its common stock and does not anticipate paying such dividends in the foreseeable
future. The payment of dividends, if any, will be determined by the Board in light of conditions then existing and may be paid
on the common stock subject to the prior rights and preferences, if any, applicable to shares of preferred stock or any series
of preferred stock, when and if declared by the Board, out of funds legally available therefor.

 

    	 	 	 

     

    

 

Liquidation
and Distribution. If the Company voluntarily or involuntarily liquidates, dissolves or winds-up, or upon any distribution
of assets, the holders of common stock will be entitled to receive, after distribution in full of the preferential amounts, if
any, to be distributed to the holders of preferred stock or any series of preferred stock, all of the remaining assets available
for distribution equally and ratably in proportion to the number of shares of common stock held by them.

 

Material
Limitation or Qualification of Rights of Common Stock

 

Preferred
Stock, Generally. The Company may issue preferred stock with such powers, preferences, rights, qualifications, limitations,
and restrictions as the Board may, without prior stockholder approval, establish. The existence, and potential future issuance,
of shares of preferred stock by the Company could result in substantial dilution of the economic and governance rights of holders
of the Company’s common stock.

 

As
of December 31, 2019, the Company’s authorized shares of preferred stock are designated into series as follows: 37,500 shares
as Series B Convertible Preferred Stock (“Series B Preferred Stock”), 1,700 shares as Series G 1.5% Convertible Preferred
Stock (“Series G Preferred Stock”), 1,250,000 shares as 9% Cumulative Convertible Preferred Stock (“9% Preferred
Stock”), 205,000 shares as Series A Junior Participating Preferred Stock (“Series A Preferred Stock”), and 3,505,800
shares are undesignated and may be issued with such rights and powers as the Board may designate.

 

Series
B Preferred Stock. As of December 31, 2019, 37,500 shares of Series B Preferred Stock are issued and outstanding. Each share
of Series B Preferred Stock is convertible into approximately 0.00030 shares of common stock at an effective conversion price
of $2,208.375 per share of common stock, which is subject to adjustment under certain circumstances. As of December 31, 2019,
the shares of Series B Preferred Stock outstanding are convertible into 11 shares of common stock. Shares of Series B Preferred
Stock do not entitle the holder to voting rights. The Company may redeem the Series B Preferred Stock for $25,001, equivalent
to $0.6667 per share, an amount equal to the liquidation preference, at any time upon 30 days prior notice.

 

Series
G Preferred Stock. As of December 31, 2019, no shares of Series G Preferred Stock are issued and outstanding. If issued, each
share of Series G Preferred Stock is convertible into that number of shares of common stock determined by dividing $1,000 by an
initial conversion price of $0.0033. The conversion price with respect to a share of Series G Preferred Stock is subject to adjustment
upon certain events that occur while such share is outstanding, pursuant to Section 7 of the Certificate of Designation for the
Series G Preferred Stock (see Exhibit 3.7 to the Company’s Annual Report on Form 10-K of which this exhibit is a part).
As of December 31, 2019, the conversion price with respect to Series G Preferred Stock is not subject to adjustment because no
shares of Series G Preferred Stock are outstanding. If issued, each outstanding share of Series G Preferred Stock, prior to the
date such share is eligible for conversion, entitles the holder to 303,030 votes per share (which may be subject to adjustment
as described above), and thereafter, each share entitles the holder to voting rights on an as-converted basis.

 

    	 	 	 

     

    

 

9%
Preferred Stock. As of December 31, 2019, no shares of 9% Preferred Stock are issued and outstanding. If issued, each share
of 9% Preferred Stock is convertible into shares of common stock according to a conversion rate subject to adjustment upon the
occurrence of certain events, including a reverse stock split, as set forth under the Certificate of Incorporation (see Exhibit
3.1 to the Company’s Annual Report on Form 10-K of which this exhibit is a part). Thereunder, each share of 9% Preferred
Stock is convertible into that number of shares of common stock determined by dividing $1.00 by a conversion rate of $1.50, subject
to adjustment pursuant to the reverse stock split effected by the Company on September 1, 2016, whereby each 325 shares of common
stock was exchanged and combined into one share of common stock. Shares of 9% Preferred Stock do not entitle the holder to voting
rights.

 

Series
A Preferred Stock. As of December 31, 2019, no shares of Series A Preferred Stock are issued and outstanding. Shares of Series
A Preferred Stock do not entitle the holder to voting rights, except to the extent the holder would be entitled to vote with the
holders of common stock as set forth in the Certificate of Designation for the Series A Preferred Stock (see Exhibit 3.1 to the
Company’s Annual Report on Form 10-K of which this exhibit is a part).

 

Anti-Takeover
Provisions in the Certificate of Incorporation and Bylaws

 

Certain
provisions of the Certificate of Incorporation and Bylaws summarized below may delay, defer or prevent a tender offer or takeover
attempt, including attempts that might result in a premium over the market price for the Company’s securities.

 

The
Certificate of Incorporation and Bylaws provide: (i) that the Company may issue preferred stock with such powers, preferences,
rights, qualifications, limitations, and restrictions as the Board may, without prior stockholder approval, establish, as described
above; and (ii) that special meetings of stockholders may only be called by the chairman of the Board, the president, the secretary,
a majority of the members of the Board or the holders of a majority of the shares of common stock then outstanding.Exhibit 4.1

      

      

      PLACEMENT AGENCY AGREEMENT

      

      

      April 9, 2020

      

      

      Seanergy Maritime Holdings Corp.

      154 Vouliagmenis Avenue

      166 74 Glyfada

      Athens, Greece

      Attention: Stamatios Tsantanis, Chief Executive Officer

      

      

      Dear Mr. Tsantanis:

       

      

      This agreement (the “Agreement”) constitutes the agreement between Maxim Group LLC (the “Placement Agent”)
        and Seanergy Maritime Holdings Corp., a Republic of the Marshall Islands corporation (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 registered
        common shares (the “Shares”) of the Company, par value $0.0001 per share (the “Common Stock”) and unregistered Warrants (collectively, the “Warrants”) to purchase shares of Common Stock
          (the shares of Common Stock underlying the Warrants, collectively with the Warrants and 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) and the form of the Warrants 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.  With 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 U.S. Securities and Exchange Commission (the “Commission”) a registration statement on Form F-3 (Registration No. 333-226796), and amendments thereto, and related preliminary prospectuses, for the registration under the Securities Act of 1933, as amended (the “Securities Act”), of the Shares, which registration statement, as so amended (including post-effective amendments, if any) became effective on August 17, 2018.  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 Shares 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

        
          

      

      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 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 the other documents the Company has filed or furnished with the Commission.

       

      

      
        3

        
          

      

      B.          Covenants of the Company. The Company has delivered, or will as
        promptly as practicable deliver, to the Placement Agent materially 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 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.  In
        accordance with Section 3(j) of that certain Underwriting Agreement dated March 31, 2020 by and between the Placement Agent and the Company, the Placement Agent consents to the entry by the Company into the Transaction Documents and the
        consummation of the transactions contemplated thereunder.

       

      

      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 percent (7%) of the
          aggregate gross proceeds raised in the Placement.  The Cash Fee shall be paid at the closing of the Placement (the “Closing”).

      

      

      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 incurred, including the reasonable fees, costs and disbursements of its legal counsel, in an amount not to exceed an aggregate of $40,000 (against invoices provided to the Company).  The Company will
        reimburse Placement Agent directly upon the Closing of the Placement from the gross proceeds raised in the Placement.

      

      

      C.          In addition, if within the Participation Period (as defined below) the Company completes any financing of equity,
          equity-linked, or debt of the Company (other than the exercise by any person or entity of any options, warrants or other convertible securities) with any of the investors (not to exceed ten such investors), each of whom was introduced to the
          Company or contacted by the Placement Agent on the Company’s behalf during the period beginning on March 2, 2020 and ending on the Closing, which are identified to the Company in writing by the Placement Agent at or prior to Closing (the “PA Investors”), then the Company will pay to the Placement Agent upon the closing of such financing as a financing participation right the compensation set forth in Section 3(A) above with respect the funds
          received by the Company from the PA Investors.  The “Participation Period” shall be the period of time six (6) months after the Closing.

      

      

      D.         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.

       

      

      
        4

        
          

      

      SECTION 5.       ENGAGEMENT TERM. The Placement Agent’s engagement hereunder shall be until the earlier of (i) the final closing date of the Placement, (ii) the date a party
        terminates the engagement according to the terms of the next sentence, and (iii) April 30, 2020 (the period of time during which this Agreement remains in effect is referred to herein as the “Term”).  If the
        Company elects to terminate this Agreement prior to Closing for any reason even though the Placement Agent was prepared to proceed with the Closing within the intent of this Agreement, and if within six (6) months following such termination, the
        Company completes any financing of equity, equity-linked or debt or other capital raising activity of the Company (other than the exercise by any person or entity of any options, warrants or other convertible securities) with any PA Investor, then
        the Company will pay the Placement Agent upon the closing of such financing the compensation set forth in Section 3(A) above to the extent of the gross proceeds received by the Company from such PA Investors.  Notwithstanding anything to the
        contrary contained herein, the provisions concerning confidentiality and 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 agrees 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 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 provisions hereof, to the performance by the Company and its subsidiaries of their obligations hereunder, and to each of the following additional terms and conditions, except as otherwise disclosed to and acknowledged and waived by the
        Placement Agent to 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 reasonable opinion of counsel for the Placement Agent, is material or omits to state any fact which, in the reasonable opinion of such counsel,
        is material and is required to be stated therein or is necessary to make the statements therein not misleading.

       

      

      
        5

        
          

      

      C.         All corporate proceedings and other legal matters incident to the authorization, form, execution, delivery and validity of each of this Agreement, the Shares, 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 Date, in form and substance reasonably satisfactory to the Placement Agent.

      

      

      E.         On the Closing Date, the Placement Agent shall have received a “comfort” letter from Ernst & Young (Hellas) Certified

        date, addressed to each of the Placement Agent and in form and substance satisfactory in all respects to the Placement Agent and Placement Agent’s counsel.

      

      

      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
        contemplated by this Agreement and except as to representations and warranties that were expressly limited to a state of facts existing at a time prior to the applicable Closing Date, and that, as of the applicable date, the obligations to be
        performed by the Company hereunder on or prior thereto have been fully performed in all material respects.  Such officer shall also provide a customary certification as to such accounting or financial matters that are included or incorporated by
        reference in the Registration Statement or the Prospectus Supplement that E&Y is unable to provide assurances on in the letter contemplated by Section 8(E) above.

      

      

      G.         On the Closing Date, Placement Agent shall have received a certificate of the Secretary of the Company, dated, as applicable, as of the date of such Closing, certifying to the
        organizational documents, good standing in the state of incorporation of the Company and board resolutions relating to the Placement of the Securities from the Company.

      

      

      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.

       

      

      
        6

        
          

      

      I.           The Common Stock is registered under the Exchange Act and, as of the Closing Date, the Shares shall be listed and admitted and authorized for trading on the Trading Market or other
        applicable U.S. national exchange, or an application for such listing shall have been submitted to the Trading Market, 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 Stock under the Exchange Act or delisting or suspending from trading the Common Stock from the Trading Market or other applicable U.S. national exchange, nor,
        except as disclosed in the Base Prospectus, Time of Sale Prospectus and Prospectus Supplement, 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.

      

      

      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
        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.       [RESERVED].

       

      

      
        7

        
          

      

      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 Watson Farley & Williams LLP, 250 West 55th Street, 31st Floor, New York, New York
        10019, 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 Placement Agent, the directors, officers, partners, members, managers, employees and agents of the Placement 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 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 Placement
        Agent, the directors, officers, partners, members, managers, employees and agents of the Placement 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, except for that certain Underwriting Agreement dated March 31, 2020 by and between the Placement Agent and the Company. 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.

       

      

      
        8

        
          

      

      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 agrees, 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 of this Agreement, (ii) is or becomes available to a Placement Agent or any of its Representatives on a non-confidential basis from a third-party, (iii) is known to a Placement Agent or any of its
        Representatives prior to disclosure by the Company or any of its Representatives, or (iv) is or has been independently developed by a Placement Agent and/or the Representatives without use of any Confidential Information furnished to it by the
        Company. The term “Representatives” shall mean the Placement Agent’s directors, board committees, officers, employees, financial advisors, attorneys and accountants. This provision shall be in full force until the earlier of (a) the date that the
        Confidential Information ceases to be confidential and (b) two years from the date hereof.  Notwithstanding any of the foregoing, in the event that the Placement Agent or any of their respective Representatives are required by Legal Requirement to
        disclose any of the Confidential Information, such Placement Agent and their respective Representatives will furnish only that portion of the Confidential Information which such Placement Agent or their respective Representative, as applicable, is
        required to disclose by Legal Requirement as advised by counsel, and will use reasonable efforts to obtain reliable assurance that confidential treatment will be accorded the Confidential Information so disclosed.

       

      SECTION 13.     NOTICES. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and
        effective on the earliest of (a) the date of transmission, if such notice or communication is sent to the email address specified on the signature pages attached hereto prior to 6:30 p.m. (New York City time) on a business day, (b) the next
        business day after the date of transmission, if such notice or communication is sent to the email address on the signature pages attached hereto on a day that is not a business day or later than 6:30 p.m. (New York City time) on any business day,
        (c) the third business day following the date of mailing, if sent by U.S. internationally recognized air courier service, or (d) upon actual receipt by the party to whom such notice is required to be given. The address for such notices and
        communications shall be as set forth on the signature pages hereto.

      

      

      SECTION 14.     PRESS ANNOUNCEMENTS. The Company agrees that the Placement Agent shall, from and after any Closing, have the right to reference the Placement and the Placement Agent’
        role in connection therewith in the Placement Agent’ marketing materials and on its website and to place advertisements in financial and other newspapers and journals, in each case at its own expense.

      ADDENDUM A

      INDEMNIFICATION PROVISIONS

       

      

      In connection with the engagement of Maxim Group LLC (the “Placement Agent”) by Seanergy Maritime Holdings Corp. (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.
