Item 5:Full Description of Material Change

On June 16, 2020, the Company announced that it has closed its previously announced Offering priced at-the-market under Nasdaq rules of an aggregate of 3,883,036 Units at a price of US$2.97375 per Unit for aggregate gross proceeds to the Company of approximately US$11.5 million, before deducting placement agent’s fees and estimated expenses of the Offering payable by the Company.

H.C. Wainwright & Co. acted as the exclusive placement agent for the Offering.

Each Unit consists of one common share of the Company and three-quarters of one warrant (each whole warrant, a “Warrant”) to purchase one common share. Each Warrant entitles the holder to acquire one common share of the Company at a price of US$2.88 at any time prior to June 16, 2025.

After deducting the placement agent’s fees and other offering expenses payable by Neovasc, the Company received net proceeds of approximately US$10.4 million. Neovasc intends to use the net proceeds from the Offering for the development and commercialization of the Neovasc Reducer™, development of the Tiara™ and general corporate and working capital purposes.

The Units and the securities comprising the Units were offered pursuant to a shelf registration statement (including a prospectus) previously filed with and declared effective by the Securities and Exchange Commission (the “SEC”) on July 13, 2018 and were qualified for distribution in each of the provinces of British Columbia, Alberta, Saskatchewan, Manitoba and Ontario by way of a final prospectus supplement to the Company’s base shelf prospectus dated July 12, 2018. The Company offered and sold the securities in the United States only. No securities were offered or sold to Canadian

purchasers.

A prospectus supplement and accompanying prospectus relating to the Offering have been filed with the SEC and are available for free on the SEC’s website at www.sec.gov and are also available on the Company’s profile on the SEDAR website at www.sedar.com.  Electronic copies of the final prospectus supplement and the accompanying prospectus relating to the Offering may be obtained from H.C. Wainwright & Co., LLC, 430 Park Avenue 3rd Floor, New York, NY 10022, or by calling (646) 975-6996 or by emailing placements@hcwco.com.

The Company relied upon the exemption set forth in Section 602.1 of the TSX Company Manual, which provides that the Toronto Stock Exchange will not apply its standards to certain transactions involving eligible interlisted issuers on a recognized exchange, such as the Nasdaq Capital Market.
