On July 24, 2019, Salarius Pharmaceuticals, Inc. (“Salarius”) and its wholly owned subsidiary Flex Innovation Group LLC (together with Salarius, the “Selling Parties”) completed its sale of specified assets related to the HOTSHOT business, pursuant to an Asset Purchase Agreement (the “Purchase Agreement”) with Cliff-Cartwright Corporation (the “Purchaser”) dated July 23, 2019. Under the Purchase Agreement, the Selling Parties agreed to sell certain contracts, inventory, goodwill, and intangible assets related to the HOTSHOT business, in consideration for $320,000, subject to certain adjustments.

The Purchase Agreement includes certain customary representations, warranties and covenants of the Selling Parties and the Purchaser. There is no material relationship between the Selling Parties and the Purchaser other than in respect of the Purchase Agreement.

The foregoing description of the Purchase Agreement included herein is not complete and is subject to and qualified in its entirety by reference to the Purchase Agreement, a copy of which is attached hereto as Exhibit 2.1 and incorporated herein by reference.

The information set forth in Item 1.01 of this Current Report on Form 8-K is incorporated by reference into this Item 2.01.

(a) On July 19, 2019, Salarius engaged Ernst & Young LLP as its independent registered public accounting firm for the fiscal year ending December 31, 2019, and dismissed Weaver & Tidwell, L.L.P. as principal accountants of Salarius Pharmaceuticals, LLC (“Private Salarius”). The decision to change accountants was approved by the audit committee of Salarius’ board of directors.

The report of Weaver & Tidwell, L.L.P. on Private Salarius’ financial statements for the years ended December 31, 2018 and 2017 did not contain an adverse opinion or disclaimer of opinion, nor was it qualified or modified as to uncertainty, audit scope, or accounting principles.

During the years ended December 31, 2018 and 2017, there were no: (1) disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) with Weaver & Tidwell, L.L.P. on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreement if not resolved to the satisfaction of Weaver & Tidwell, L.L.P. would have caused Weaver & Tidwell, L.L.P. to make reference thereto in its reports on the financial statements for such years, or (2) reportable events (as described in Item 304(a)(1)(v) of Regulation S-K).

Salarius has provided Weaver & Tidwell, L.L.P. with the disclosures under this Item 4.01(a), and has requested and received from Weaver & Tidwell, L.L.P. a copy of the letter addressed to the SEC stating that Weaver & Tidwell, L.L.P. agrees with the above statements. A copy of the letter from Weaver & Tidwell, L.L.P. is attached as Exhibit 16.1 and incorporated herein by reference.

(b) On July 19, 2019, the audit committee of Salarius’ board of directors approved the engagement of Ernst & Young LLP as Salarius’ independent registered public accounting firm for the fiscal year ending December 31, 2019. Prior to the completion of the merger of Private Salarius with and into Flex Pharma, Inc.’s wholly owned subsidiary Falcon Acquisition Sub, LLC, Ernst & Young LLP served as the auditor of Flex Pharma, Inc.

During the years ended December 31, 2018 and 2017, and the subsequent interim period through July 18, 2019, neither Private Salarius nor anyone on its behalf consulted with Ernst & Young LLP, regarding either (i) the application of accounting principles to a specific transaction, completed or proposed, or the type of audit opinion that might be rendered on Private Salarius’ financial statements, and neither a written report nor oral advice was provided to Private Salarius that Ernst & Young LLP concluded was an important factor considered by Private

Salarius in reaching a decision as to any accounting, auditing or financial reporting issue or (ii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a reportable event (as described in Item 304(a)(1)(v) of Regulation S-K).

On July 24, 2019, Salarius issued a press release announcing the transaction with respect to its sale of assets related to the HOTSHOT business. A copy of the press release is furnished as Exhibit 99.1 hereto.

Purchaser (a) is a corporation duly organized, validly existing, and in good standing under the laws of the State of Delaware; and (b) is qualified to do business in all jurisdictions in which the ownership, leasing or operation of its assets or the nature of its business makes such qualification necessary, except where failure to so qualify, individually or in the aggregate, would not reasonably be expected to have a material adverse effect on Purchaser.

Section 4.3 No Breach; Approvals.

(a) The execution, delivery, and performance by Purchaser of this Agreement and compliance with the terms and provisions hereof do not and will not violate or conflict in any respect with (with or without notice or lapse of time or both), or result in a breach of, or require

Section 4.5 OFAC. Neither Purchaser nor any of its affiliates nor any director, officer, agent or employee of Purchaser or any of its subsidiaries is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”).

COVENANTS

Section 5.1 Commercially Reasonable Efforts.

(a) Subject to the terms and conditions of this Agreement, Selling Parties and Purchaser shall each use commercially reasonable efforts (subject to, and in accordance with, applicable laws) to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other Parties hereto in doing, all things necessary, proper or advisable under applicable laws to consummate, and make effective, in the most expeditious manner practicable, the transactions contemplated by this Agreement.

13

(b) Without limiting the generality of the foregoing obligations, Selling Parties agree to use commercially reasonable efforts to facilitate Purchaser’s making the transfer filings with the United States Patent and Trademark Office, the United States Copyright Office, and with the registries and other recording governmental authorities in all applicable foreign jurisdictions to ensure that the chain of title of each registration for and each application for registration for Company Intellectual Property reflects all prior acquisitions and transfers of such item (including between Parent and Company) and the release of any prior security interests, and that Purchaser shall be identified in the records of the applicable governmental authority as the current owner of record, without break in chain of title, of each such registration for and application for registration for Company Intellectual Property, free and clear of all Liens. Selling Party’s obligations under this Section 5.1(b) shall continue until all applications and registrations for Company Intellectual Property in all jurisdictions have been updated to reflect Purchaser as record owner.

(c) In addition, without limiting the generality of the foregoing obligations, Selling Parties agree to use commercially reasonable efforts to facilitate the transition to Purchaser of all material vendor relationships relating to the Business such that Purchaser shall be able to continue operations of the Business without interruption, and on substantially the same pricing and other terms with the Company’s material vendors, following Closing.

Section 5.2    Certain Tax Matters.

(a) Selling Parties and Purchaser shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of tax returns and any audit, litigation or other proceeding with respect to taxes, provided, however, that nothing in this Agreement shall require Parent to provide or otherwise make available to Purchaser a copy of its tax return.

(b) All sales, use, value added, documentary, stamp, gross receipts, registration, transfer, conveyance, excise, recording, license, stock transfer stamps, and other similar Taxes and fees (“Transfer Taxes”) incurred in connection with the transactions contemplated by this Agreement shall be borne fifty percent (50%) by Selling Parties and fifty percent (50%) by Purchaser. The appropriate party will prepare and file all necessary Tax Returns and other documentation with respect to Transfer Taxes and, if required by applicable Laws, the other party will (and will cause its Affiliates to) join in the execution of any such Tax Returns and other documentation.

Section 5.3 Restrictive Covenants. The Parties agree that Purchaser is relying on the covenants and agreements set forth in this Section 5.3, that without such covenants Purchaser would not enter into this Agreement or consummate the transactions contemplated hereby and that the Purchase Price is sufficient consideration to make the covenants and agreements set forth herein enforceable.

(a) Non-Competition. Each Selling Party agrees that during the two year period following the Closing (the “Restricted Period”), such Selling Party shall not, nor shall it cause any of its Affiliates to, directly or indirectly, either individually, in partnership, jointly, or in conjunction with, or on behalf of, any other Person: (i) have or acquire any ownership interest in

14

(whether as proprietor, partner, stockholder or otherwise) or lend money to, (ii) be an officer, director or general or managing partner of, or hold a similar position in, (iii) act as agent, broker or distributor for, or adviser or consultant to, or (iv) be employed in a position with management or supervisory authority as to, or material involvement with, overall operations, administration, or sales of, any business (regardless of the form in which conducted) which is engaged, or which Selling Party reasonably knows is undertaking to become engaged, in any the manufacture, sale, distribution, license or marketing of any consumer product that does not require a physician’s prescription to purchase, and the testing or sale of which does not require the approval of the FDA, for the treatment or prevention of muscle cramping, pain associated with athletic activity, or nocturnal leg cramps (a “Competitive Business”). Nothing herein shall preclude any Selling Party or any of its Affiliates from (1) purchasing or owning not more than one percent (1%) of the total outstanding stock of a publicly-held company with securities traded on a nationally or internationally recognized securities exchange, or (2) being a passive investor in any independently managed mutual fund.

(b) Blue-Pencil. If any court of competent jurisdiction will, at any time, deem the term of any particular restrictive covenant contained in this Section 5.3 too lengthy, the geographic area covered too extensive or the scope too broad, the other provisions of this Section 5.3 will nevertheless stand, and the covenant, as determined by a court of competent jurisdiction, will be deemed reformed such that the term will be deemed to be the longest period permissible by Law under the circumstances, the geographic area covered will be deemed to comprise the largest territory permissible by Law under the circumstances and the scope will be as broad as permissible by Law under the circumstances. The court of competent jurisdiction in each case will reduce the term, geographic area and or scope covered to permissible duration, size or breadth.

(c) Confidential or Proprietary Information. From and at all times following the date of this Agreement, each Selling Party shall, and shall cause its Affiliates to: (i) hold in confidence any and all Confidential Information (as defined below) whether written or oral, (ii) not disclose any Confidential Information to any Person whatsoever, other than to Selling Parties, Purchaser, or their Affiliates or their respective representatives or legal and business advisors on a confidential need-to-know basis, or (iii) sell or use any Confidential Information in any manner whatsoever for the direct or indirect benefit of any Person other than Purchaser or its Affiliates. For purposes hereof, “Confidential Information” means the confidential or proprietary business information of Company or the Business other than any Excluded Assets, whether or not marked as such, including any business plans, technology, plans, blueprints, drawings, models, designs, templates, processes, formulae, computer programs, customer lists, supplier lists, pricing data, financial data, trade secrets or other information identified or otherwise treated as confidential or proprietary business information, including the terms and existence of this Agreement and the other documents contemplated hereby and the consummation of the transactions contemplated hereby and thereby; provided, however, that Confidential Information shall not include any information to the extent Selling Parties can show that such information: (x) is, at the time of attempted disclosure, sale or use, generally available to and known by the public through no fault of Selling Parties, their Affiliates, or their respective representatives, or (y) is lawfully acquired after the Closing by the Person attempting disclosure, sale or use from sources which are not prohibited from disclosing such information by a legal, contractual or fiduciary obligation. If any Person restricted by this Section 5.3(c)

15

is compelled to disclose any information by judicial or administrative process or by other requirements of applicable Law, including any disclosure requirements pursuant to Parent’s public reporting requirements under the Securities Act, Selling Parties shall promptly notify Purchaser in writing (to the extent not prohibited by 17 CFR §240.21F-7(a)), and shall cause the applicable party to disclose only that portion of such information which it is advised by its counsel is legally required to be disclosed, provided Selling Parties shall use reasonable best efforts to obtain an appropriate protective order or other reasonable assurance that confidential treatment will be accorded such information (provided all such efforts shall be at Purchaser’s expense).

(d) Remedies. Each Selling Party represents that it is familiar with the covenants contained herein and is fully aware of its obligations hereunder. Each Selling Party further agrees that the length of time, scope and geographic coverage is reasonable given the benefits it has received hereunder. Each Selling Party further acknowledges and agrees that the covenants set forth in this Section 5.3 are necessary for the protection of Purchaser’s business interests, including the goodwill and Confidential Information being transferred by reason of the transaction, that irreparable injury will result to Purchaser if any Selling Party breaches any of the terms of this Section 5.3, and that in the event of an actual or threatened breach by a Selling Party of any of the provisions contained in this Section 5.3, Purchaser will have no adequate remedy at Law. Each Selling Party accordingly agrees that in the event of any actual or threatened breach by it of any of the provisions contained in this Section 5.3, Purchaser will be entitled to injunctive and other equitable relief. Nothing contained herein will be construed as prohibiting Purchaser from pursuing any other remedies available to it for such breach or threatened breach, including the recovery of any damages that it is able to prove. Each Selling Party will be liable for any breach by its respective Affiliates of this Section 5.3.

Section 5.4 Excluded Intellectual Property.

(a) The Selling Parties covenant and agree as follows:

(i) The Selling Parties shall not use, develop, license, sublicense, assign, transfer, convey, sell or maintain any Intellectual Property set forth on Schedule 3.8(g) now or at any time in the future;

(ii) The Selling Parties shall abandon and permit to lapse forthwith all Intellectual Property set forth on Schedule 3.8(g); and

(iii) The Selling Parties shall not, and shall not permit any other party, now or at any time in the future, to, initiate, pursue, participate in, or assist with, any claim, counterclaim or cause of action asserting or claiming that any patent, patent application or related right described in Schedule 2.1(d) is in violation of, infringes upon, or in any way damages or harms any Selling Party product or service or any patent, patent application or any related right whatsoever described in Schedule 3.8(g).

(b) Notwithstanding anything else, the covenants set forth in this Section 5.4 shall be binding on the Selling Parties and each of their successors and assigns as of the Closing Date and thereafter without expiry, and shall inure to the benefit of the Purchaser and its successors and assigns as of the Closing Date and thereafter without expiry.

Salarius Pharmaceuticals Successfully Monetizes Legacy Consumer Product

Completes Sale of HOTSHOT

Houston, TX – July 24, 2019 – Salarius Pharmaceuticals, Inc. (Nasdaq: SLRX), a clinical-stage oncology company targeting the epigenetic causes of cancers, today announced it completed the sale of HOTSHOT, a novel consumer beverage formerly marketed by Flex Innovation Group LLC, a subsidiary of Salarius Pharmaceuticals, Inc. (f/k/a Flex Pharma, Inc.), pursuant to an asset purchase agreement with Cliff-Cartwright Corporation. HOTSHOT is used by endurance athletes who drink it before, during, and after exercise to prevent and treat Exercise Associated Muscles Cramps (EAMCs).

Prior to completing the merger with then privately-held Salarius Pharmaceuticals LLC, Flex Pharma announced its intent to sell its consumer division as part of a broader effort to seek strategic alternatives to enhance stockholder value, including the potential sale of certain assets of Flex Innovation Group LLC.

David Arthur, President and CEO of Salarius Pharmaceuticals, stated, “Salarius Pharmaceuticals is a clinical-stage oncology company with a differentiated epigenetic therapy targeting areas of high unmet medical need including Ewing sarcoma and advanced solid tumors. We are focused on advancing our products through clinical development and we are pleased that HOTSHOT has found a home with Cliff-Cartwright Corporation. This transaction allows us to focus on clinical development.”

Matthew Wohl, President and CEO of Cliff-Cartwright Corporation, commented, “Since its founding by two endurance athletes, who also happen to be highly acclaimed scientists, HOTSHOT has been helping athletes perform and compete at every level. We are thrilled to continue building the HOTSHOT brand and believe in its mission of preventing muscle cramping and soreness for endurance athletes and fitness enthusiasts alike.”
