Subject Company: Salarius Pharmaceuticals, LLC
SEC File No.:
Flex Pharma, Inc. intends to send the following communication to certain of its stockholders.
I spoke to our proxy solicitor and it told me that
it believes that your shares are held in your brokers name so I cannot send your [voting] [proxy] card directly. Instead, you will need to [contact and] instruct your broker to vote on your behalf. Is that possible? [You are a significant
stockholder of Flex so] [y]our vote is important to us. With that being said, below is information on the proposed merger. As noted below and in the proxy materials, we ask that you please vote FOR proposals 1, 2, 3, and 4, ALL of which are needed
to support the merger. Please let me know if you have any questions or would like to speak to our [CEO] [CFO].
Thank you for the time and support,
