However, as more fully described in Item 4, the securities reported in rows (6), (8) and (9) show the number of shares of Common Stock that would be issuable upon full conversion or exercise of such reported securities and do not give effect to such blockers. Therefore, the actual number of shares of Common Stock beneficially owned by such Reporting Person, after giving effect to such blockers, is less than the number of securities reported in rows (6), (8) and (9).

This Amendment No. 1 (this “Amendment”) amends the statement on Schedule 13G filed on June 14, 2017 (the “Original Schedule 13G”) with respect to the Common Stock, $0.0001 par value (the “Common Stock”) of CHF Solutions, Inc., a Delaware corporation (the “Company”). Capitalized terms used herein and not otherwise defined in this Amendment have the meanings set forth in the Original Schedule 13G. This Amendment amends and restates Item 4 in its entirety as set forth below.

Item 4.

Ownership

Provide the following information regarding the aggregate number and percentage of the class of securities of the issuer identified in Item 1.

The information as of the date of the event which requires filing of this statement required by Items 4(a) – (c) is set forth in Rows 5 – 11 of the cover page for each Reporting Person hereto and is incorporated herein by reference for each such Reporting Person. The percentage set forth in Row 11 of the cover page for each Reporting Person is based on 625,791 shares of common stock outstanding as of October 31, 2017, as reported in the final prospectus filed by the Issuer pursuant to Rule 424(b)(4) with the Securities and Exchange Commission on November 22, 2017, and the conversion of the Convertible Preferred Stock (the “Reported Preferred Stock”) and the exercise of the reported warrants (the “Reported Warrants”), in each case subject to the Blockers (as defined below).

Pursuant to the terms of the Certificate of Designations governing the Reported Preferred Stock and the terms of the Reported Warrants, the Reporting Persons cannot convert the Reported Preferred Stock or exercise the Reported Warrants to the extent the Reporting Persons would beneficially own, after any such conversion or exercise, more than 4.99% of the outstanding shares of Common Stock with respect to the Reported Preferred Stock and more than 4.99% of the outstanding shares of Common Stock with respect to the Reported Warrants (each a “Blocker” and collectively, the “Blockers”), and the percentage set forth in Row 11 of the cover page for each Reporting Person gives effect to the Blockers. Consequently, as of the date of the event which requires filing of this statement, the Reporting Persons were not able to convert any of the Reported Preferred Stock or exercise any of the Reported Warrants due to the Blockers.

As of the date of the event which requires filing of this statement, (i) Iroquois Master Fund Ltd. (“Iroquois Master Fund”) held 13,848 shares of Common Stock, 137,145 shares of Common Stock underlying the Reported Preferred Stock and 539,200 shares of Common Stock underlying the Reported Warrants and (ii) Iroquois Capital Investment Group LLC (“ICIG”) held 19,884 shares of Common Stock, 207,167 shares of Common Stock underlying the Reported Preferred Stock and 804,800 shares of Common Stock underlying the Reported Warrants. Mr. Abbe has the sole authority and responsibility for the investments made on behalf of ICIG as its managing member and shares authority and responsibility for the investments made on behalf of Iroquois Master Fund with Ms. Page, each of whom is a director of Iroquois Master Fund. As such, Mr. Abbe may be deemed to be the beneficial owner of all shares of Common Stock held by, and underlying the Reported Preferred Stock and Reported Warrants (subject to the Blockers) held by, Iroquois Master Fund and ICIG. Iroquois is the investment manager for the Fund and Mr. Abbe is the President of Iroquois. The foregoing should not be construed in and of itself as an admission by any Reporting Person as to beneficial ownership of shares of Common Stock owned by another Reporting Person. Each of the Iroquois Funds and the Reporting Individuals hereby disclaims any beneficial ownership of any such shares of Common Stock, except to the extent of their pecuniary interest therein.
