We have acted as counsel to Heritage Global Inc., a Florida corporation (the “Company”) in connection with the Company’s registration statement on Form S-3 (the “Registration Statement”), including the prospectus constituting a part thereof (the “Prospectus”), to be filed with the Securities and Exchange Commission (the “Commission”) on the date hereof pursuant to the Securities Act of 1933, as amended (the “Securities Act”).

The Prospectus provides that it will be supplemented in the future by one or more supplements to the Prospectus (each, a “Prospectus Supplement”). The Prospectus, as supplemented by various Prospectus Supplements, will provide for the registration for issue and sale by the Company of up to $150,000,000 offering price of (i) shares of the Company’s common stock, $0.01 par value per share (“Common Stock”), (ii) shares of one or more series of the Company’s preferred stock, $10.00 par value per share (“Preferred Stock”), (iii) warrants to purchase Common Stock or Preferred Stock (the “Warrants”), (v) rights to purchase Common Stock or Preferred Stock (the “Rights”), (vi) units composed of any of the foregoing (the “Units”), (vii) senior debt securities, in one or more series (the “Senior Debt Securities”), which may be issued pursuant to an indenture to be dated on or about the date of first issuance of Senior Debt Securities thereunder, by and between a trustee to be selected by the Company (the “Trustee”) and the Company, as such indenture may be supplemented from time to time (the “Senior Indenture”), and (viii) subordinated debt securities, in one or more series (the “Subordinated Debt Securities” and, together with the Senior Debt Securities, the “Debt Securities”), which may be issued pursuant to an indenture to be dated on or about the date of the first issuance of Subordinated Debt Securities thereunder, by and between the Trustee and the Company (the “Subordinated Indenture” and, collectively with the Senior Indenture, an “Indenture,” in substantially the form filed as Exhibit 4.7 to the Registration Statement, as such Indenture may be supplemented from time to time). The Common Stock, Preferred Stock, Warrants, Rights, Units, and Debt Securities, plus any additional Common Stock, Preferred Stock, Warrants, Rights, Units and Debt Securities that may be registered pursuant to any subsequent registration statement that the Company may hereafter file with the Commission pursuant to Rule 462(b) under the Securities Act in connection with the offering by the Company contemplated by the Registration Statement, are referred to herein collectively as the “Securities.” The Securities may be sold from time to time and on a delayed or continuous basis as set forth in the Prospectus, and as to be set forth in one or more Prospectus Supplements. In connection with the Registration Statement, you have requested our opinion with respect to the matters set forth below.

In rendering our opinion, we have reviewed the Registration Statement and the exhibits thereto. We have also reviewed such corporate documents and records of the Company, such certificates of public officials and such other matters as we have deemed necessary or appropriate for purposes of this opinion. We also have been furnished with, and have relied upon, oral or written statements and representations of officers and other representatives of the Company, public officials and others. We have not independently verified such factual matters.

Except to the extent we opine as to the binding effect and/or enforceability of certain documents as set forth in paragraphs 3, 4, 5 and 6 below, we have assumed that all documents referenced below are the valid and binding obligations of and enforceable against the parties thereto. We have also assumed the legal capacity of all natural persons, the legal power and authority of all persons signing on behalf of other parties, the authenticity of all documents submitted to us as originals, the genuineness of all signatures, and the conformity to authentic original documents of all documents submitted to us as certified, conformed or photostatic copies. We have further assumed that the Articles of Incorporation and Bylaws shall be in full force and effect and shall not have been amended, restated, supplemented or otherwise altered, and there shall be no authorization of any such amendment, restatement, supplement or alteration, in each case since the date hereof.

The opinions expressed below are also based on the assumption that the Registration Statement has been filed by the Company with the Commission and will be effective at the time that any of the Securities are issued, that persons acquiring the Securities will receive a Prospectus (and any related Prospectus Supplement(s)) containing all of the information required by Part I of the Registration Statement before acquiring such Securities, and that no stop order suspending the Registration Statement’s effectiveness will have been issued and remain in effect.

Based on the foregoing, and subject to the assumptions, limitations and qualifications set forth herein, we are of the opinion that:

1. (a) When an issuance of Common Stock has been duly authorized by all necessary corporate action of the Company, upon issuance, delivery and payment therefor in an amount not less than the par value thereof in the manner contemplated by the Registration Statement, the Prospectus and the related Prospectus Supplement(s) and by such corporate action, and (b) assuming the total amounts and numbers of shares, including Common Stock that may be issued upon conversion or exercise of any other Securities convertible into or exercisable for Common Stock, do not exceed the respective total amounts and numbers of shares (i) available under the Company’s Amended and Restated Articles of Incorporation (“Articles of Incorporation”), and (ii) authorized by the Board of Directors in connection with the offering contemplated by the applicable Prospectus and the related Prospectus Supplement(s), and (c) assuming, if applicable, the issuance of Common Stock that may be issued upon conversion or exercise of any other Securities convertible or exercisable for Common Stock is so issued in accordance with the terms of the applicable Security in the manner contemplated by the Registration Statement, the Prospectus and the related Prospectus Supplement(s), such Common Stock will be validly issued, fully paid and nonassessable.

2. (a) When a new class or series of Preferred Stock has been duly established in accordance with the terms of the Articles of Incorporation and the Company’s Bylaws, as amended (“Bylaws”), and applicable law, and duly authorized by all necessary corporate action of the Company, and (b) assuming that an appropriate certificate of amendment of the Company’s Articles of Incorporation fixing and determining the terms of such class or series of Preferred Stock has been duly approved

by the Company’s Board of Directors and been filed with and accepted for record by the Secretary of State of the State of Florida, (c) assuming that upon the issuance of such Preferred Stock, including Preferred Stock that may be issued upon conversion or exercise of any other Securities convertible into or exercisable for Preferred Stock, the total number of issued and outstanding shares of Preferred Stock will not exceed the total number of shares of Preferred Stock that the Company is then authorized to issue under its Articles of Incorporation and Bylaws, (d) assuming that upon the issuance of such Preferred Stock, including Preferred Stock that may be issued upon conversion or exercise of any other Securities convertible into or exercisable for Preferred Stock, the total number of issued and outstanding shares of the applicable class or series of Preferred Stock will not exceed the total number of shares of such class or series of Preferred Stock that the Company is then authorized to issue under its Articles of Incorporation and Bylaws, then upon issuance and delivery of and payment for such shares in the manner contemplated by the Registration Statement, the Prospectus and the related Prospectus Supplement(s) and by such corporate action, such shares of such class or series of Preferred Stock (including any Preferred Stock duly issued upon (i) the exchange or conversion of any shares of Preferred Stock that are exchangeable or convertible into another class or series of Preferred Stock, (ii) the exercise of any duly issued Warrants exercisable for Preferred Stock, (iii) the exercise of any duly issued Rights exercisable for Preferred Stock or (iv) the exchange or settlement of Units that are exchangeable or able to be settled for Preferred Stock), will be validly issued, fully paid and nonassessable.

3. (a) When a warrant agreement relating to the Warrants (the “Warrant Agreement”) has been duly authorized, executed and delivered and the Warrants and the other Securities for which the Warrants will be exercisable have been duly authorized by all necessary corporate action of the Company, and (b) assuming that the terms of the Warrants and of their issuance and sale have been duly established in conformity with the Articles of Incorporation and Bylaws and the Warrant Agreement, and (c) assuming that the terms of the Warrants as executed and delivered are as described in the Registration Statement, the Prospectus and the related Prospectus Supplement(s), and (d) assuming that the Warrants, as executed and delivered, do not violate any law applicable to the Company or result in a default under or breach of any agreement or instrument binding upon the Company, and (e) assuming that the Warrants as executed and delivered comply with all requirements and restrictions, if any, applicable to the Company, whether imposed by any court or governmental or regulatory body having jurisdiction over the Company, and (f) assuming that the Warrants are then issued and sold as contemplated in the Registration Statement(s), the Prospectus and the Prospectus Supplement(s), then upon issuance of and delivery of and payment for such Warrants in the manner contemplated by the Registration Statement, the Prospectus and the related Prospectus Supplement and the Warrant Agreement and by such corporate action, the Warrants (including any Warrants issued upon the exchange or settlement of Units that are exchangeable or able to be settled for Warrants) will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, and the Warrants will be validly issued.

4. (a) When a rights agreement relating to the Rights (the “Rights Agreement”) has been duly authorized, executed and delivered and the Rights and the other Securities for which the Rights will be exercisable have been duly authorized by all necessary corporate action of the Company, and (b) assuming that the terms of the Rights and of their issuance and sale have been duly established in conformity with the Company’s Articles of Incorporation and Bylaws and the Rights Agreement, and (c) assuming that the terms of the Rights as executed and delivered are as described in the Registration Statement, the Prospectus and the related Prospectus Supplement(s), and (d) assuming that the Rights, as executed and delivered, do not violate any law applicable to the Company or result in a default under or breach of any agreement or instrument binding upon the

Company, and (e) assuming that the Rights as executed and delivered comply with all requirements and restrictions, if any, applicable to the Company, whether imposed by any court or governmental or regulatory body having jurisdiction over the Company, and (f) assuming that the Rights are then issued and sold as contemplated in the Registration Statement, the Prospectus and the Prospectus Supplement(s), then upon issuance of and delivery of and payment for such Rights in the manner contemplated by the Registration Statement, the Prospectus and the related Prospectus Supplement(s) and the Rights Agreement and by such corporate action, the Rights (including any Rights issued upon the exchange or settlement of Units that are exchangeable or able to be settled for Rights) will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, and the Rights will be validly issued.

5. (a) When a unit agreement relating to the Units (the “Unit Agreement”) has been duly authorized, executed and delivered and the Units have been duly authorized by all necessary corporate action of the Company, and (b) assuming that the terms of the Units and of their issuance and sale have been duly established in conformity with the Unit Agreement, and (c) assuming that the terms of the Units as executed and delivered are as described in the Registration Statement, the Prospectus and the related Prospectus Supplement(s), and (d) assuming that the Units, as executed and delivered, do not violate any law applicable to the Company or result in a default under or breach of any agreement or instrument binding upon the Company, and (e) assuming that the Units as executed and delivered comply with all requirements and restrictions, if any, applicable to the Company, whether imposed by any court or governmental or regulatory body having jurisdiction over the Company, and (f) assuming that the Units are then issued and sold as contemplated in the Registration Statement, the Prospectus and the Prospectus Supplement(s), then upon issuance of and delivery of and payment for such Units in the manner contemplated by the Registration Statement(s), the Prospectus and the related Prospectus Supplement and the Unit Agreement and by such corporate action, the Units will constitute valid and binding obligations of the Company.
