4,166,667 Shares of Common Stock

Pursuant to this prospectus supplement, the accompanying prospectus supplement and the accompanying base prospectus, we are offering 4,166,667 shares of our common stock to YA II PN, Ltd., a Cayman Islands exempt limited partnership (“YA”) at a price of $0.36 per share, pursuant to our previously announced Standby Equity Purchase Agreement dated April 3, 2020 with YA (the “SEDA”). The total purchase price and proceeds we will receive from the sale of the shares is $1,500,000. Upon the settlement of the related advance notice, in the event that the per share settlement price is greater than $0.36 per share YA shall remit to us an aggregate cash amount equal to the 4,166,667 shares multiplied by the difference between the per share settlement price and $0.36 per share. These shares are being issued as part of the commitment by YA to purchase from time to time, at our option, up to $50,000,000 worth of shares of our common stock pursuant to the SEDA as described in Prospectus Supplement No. 1. We expect to issue the shares to YA on or about May 21, 2020.

In addition to our issuance of common shares to YA pursuant to the SEDA, this prospectus supplement, the accompanying prospectus supplement and the accompanying prospectus also cover the resale of those shares by YA to the public. Though we have been advised by YA, and YA represents in the SEDA, that YA is purchasing the shares for its own account, for investment purposes, and without any view or intention to distribute such shares in violation of the Securities Act or any other applicable securities laws, YA may be deemed an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act. YA Global may be deemed to be an “underwriter” within the meaning of the Securities Act of 1933, as amended.

Our common stock is quoted on the NASDAQ Capital Market under the symbol “IDEX.” The closing price of our common stock on the NASDAQ Capital Market on May 19, 2020 was $0.46 per share.

The aggregate market value of our outstanding common stock held by nonaffiliates at the time we entered into the SEDA on April 3, 2020 was $116,550,319, based on 133,965,884 shares of common stock held by nonaffiliates and a per share price of $0.87 using the closing price of our common stock on April 3, 2020. As of the date hereof, as a result of entering into the SEDA, we have offered securities with an aggregate market value of $50,000,000. After giving effect to the issuance described in this prospectus supplement, YA has purchased an aggregate of 5,870,535 shares of our common stock under the SEDA at an aggregate purchase price of $2,500,000.
