On January 31, 2019, pursuant to the terms of the Securities Purchase Agreement, the Company issued warrants (the "Warrants") to purchase an aggregate of 1,463,519 shares of its common stock, par value $0.001 per share ("Common Stock") to the Investors. The Warrants are comprised of two series of warrants, the Series A Warrants to Purchase Common Stock (the "Series A Warrants") and the Series B Warrants to Purchase Common Stock (the "Series B Warrants"). The Series A Warrants are initially exercisable for an aggregate of 1,463,519 shares of Common Stock and the Series B Warrants are initially not exercisable for any shares of Common Stock.

The Series A Warrants have an initial exercise price of $4.15, were immediately exercisable upon issuance and have a term of five years from the date of issuance. The Series A Warrants provide that, for the first three years following the issuance of the Series A Warrants, if the Company issues or sells, or is deemed to have issued or sold, any shares of Common Stock for a price per share lower than the exercise price then in effect, subject to certain limited exceptions, then the exercise price of the Series A Warrants shall be reduced to such lower price per share. If the Company issues or sells, or is deemed to have issued or sold any shares of Common Stock for a price per share lower than the exercise price then in effect after the first three years following the issuance of the Series A Warrants, subject to certain limited exceptions, then the exercise price of the Series A Warrants shall be reduced to an amount equal to the product of (i) the exercise price then in effect and (ii) the quotient determined by dividing (a) the sum of (x) the product derived by multiplying the exercise price then in effect and the number of shares of Common Stock outstanding immediately prior to the new issuance plus (y) the consideration received by the Company for the new issuance, by (b) the product derived by multiplying (1) the exercise price then in effect by (2) the number of shares of Common Stock outstanding immediately after the new issuance. In addition, the exercise price and the number of shares of Common Stock issuable upon exercise of the Series A Warrants will also be subject to adjustment in connection with stock splits, dividends or distributions or other similar transactions.

Additionally, every ninth trading day up to and including the 45th trading day (each, a "Reset Date") following (i) each date on which a registration statement registering any shares of Common Stock underlying the Warrants ("Warrant Shares") is declared effective or is available for use, (ii) if there is no registration statement registering all of the Warrant Shares, the earlier to occur of (a) the first date on which the holders can sell all the Warrant Shares without restriction or limitation pursuant to Rule 144 under the Securities Act of 1933, as amended (the "Securities Act"), and (b) July 24, 2019 (such earlier date, the "Six Month Reset Date") and (iii) in the event that the Company (a) fails for any reason to satisfy the requirements of Rule 144(c)(1) under the Securities Act or (b) has ever been an issuer described in Rule 144(i)(1)(i) under the Securities Act or becomes such an issuer in the future, and the Company fails to satisfy any condition set forth in Rule 144(i)(2) under the Securities Act (each of clauses (a) and (b), a "Public Information Failure") at any time following the Six Month Reset Date, then the earlier to occur of (1) the date the Public Information Failure is cured and no longer prevents the holder from selling all of the Warrant Shares pursuant to Rule 144 without restriction or limitation, (2) the first date on which the holders can sell all the Warrant Shares without restriction or limitation pursuant to Rule 144 under the Securities Act and without the requirement to be in compliance with Rule 144(c)(1), and (3) January 24, 2020 (such 45 trading day period, the "Reset Period" and each such 45th trading day after (i), (ii) or (iii), the "End Reset Date"), the exercise price will be adjusted to be the lesser of (i) the exercise price then in effect and (ii) 125% of 80% of the average of the five lowest volume-weighted average trading prices of a share of Common Stock as quoted on the Nasdaq Capital Market during the applicable Reset Period to date and the number of shares of Common Stock issuable upon exercise of the Series A Warrants will be proportionally increased accordingly, provided that the Company shall in no event issue shares of Common Stock pursuant to the exercise of the Warrants, in the aggregate, in excess of 15,963,030 (the "Warrant Issuance Cap"). In the event that the Company is unable to

2

issue shares of Common Stock pursuant to an exercise of Warrants due to the application of the Warrant Issuance Cap, the Company will pay to the exercising holder an amount in cash per share equal to the difference between the last closing trade price of the Common Stock and the applicable exercise price, to the extent not previously paid to the Company.

Pursuant to the Series A Warrants, the Company agreed not to enter into, allow or be party to certain fundamental transactions, generally including any merger with or into another entity, sale of all or substantially all of the Company’s assets, tender offer or exchange offer, or reclassification of the Common Stock (a "Fundamental Transaction") until the Reservation Date. Thereafter, the Company agreed not to enter into or be party to a Fundamental Transaction unless the successor entity in such transaction assumes in writing all of the Company’s obligations under the Series A Warrants, upon which the Series A Warrants shall become exercisable for shares of Common Stock, shares of the common stock of the successor entity or the consideration that would have been issuable to the holders had they exercised the Series A Warrants prior to such Fundamental Transaction, at the holders’ election. Additionally, if the successor entity is a publicly traded corporation, the holders may elect to receive an equivalent security of the successor entity, in exchange for the Series A Warrants. Any security issuable or potentially issuable to the holder pursuant to the terms of the Series A Warrants on the consummation of a Fundamental Transaction must be registered and freely tradable by the holder without any restriction or limitation or the requirement to be subject to any holding period pursuant to any applicable securities laws.

Additionally, at the request of a holder delivered before the 90th day after the consummation of a Fundamental Transaction, the Company or the successor entity must purchase such holder’s Warrant for the value calculated using the Black-Scholes option pricing model as of the day immediately following the public announcement of the applicable Fundamental Transaction, or, if the Fundamental Transaction is not publicly announced, the date the Fundamental Transaction is consummated.

The Series A Warrants also contain a "cashless exercise" feature that allows the holders to exercise the Series A Warrants without making a cash payment in the event that there is no effective registration statement registering the shares issuable upon exercise of the Series A Warrants. The Series A Warrants are subject to a blocker provision which restricts the exercise of the Series A Warrants if, as a result of such exercise, the holder, together with its affiliates and any other person whose beneficial ownership of shares of Common Stock would be aggregated with the holder’s for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), would beneficially own in excess of 4.99% or 9.99% of the outstanding shares of Common Stock (including the shares of Common Stock issuable upon such exercise), as such percentage ownership is determined in accordance with the terms of the Series A Warrants.

The Series B Warrants have an exercise price of $0.001, were immediately exercisable upon issuance and will expire on the day following the later to occur of (i) the Reservation Date, and (ii) the date on which the Series B Warrants have been exercised in full (without giving effect to any limitation on exercise contained therein) and no shares remain issuable thereunder. The Series B Warrants are initially exercisable for no shares of Common Stock. On each Reset Date, the number of shares of Common Stock issuable upon exercise of the Series B Warrants shall be increased to the number (if positive) obtained by subtracting (i) 1,829,406 from (ii) the quotient determined by dividing (a) the pro rata portion of the purchase price paid by such holder pursuant to the Securities Purchase Agreement by (b) 80% of the average of the five lowest volume-weighted average trading price of a share of Common Stock as quoted on the Nasdaq Capital Market during the applicable Reset Period to date, provided that the Company shall in no event issue shares of Common Stock pursuant to the exercise of the Warrants, in the aggregate, in excess of the Warrant Issuance Cap. In the event that the Company is unable to issue shares of Common Stock pursuant to an exercise of Warrants due to the application of the Warrant Issuance Cap, the Company will pay to the exercising holder an amount in cash per share equal to the difference between the last closing trade price of the Common Stock and the applicable exercise price, to the extent not previously paid to the Company.

Pursuant to the Series B Warrants, the Company also agreed not to enter into, allow or be party to a Fundamental Transaction until the Reservation Date. Thereafter, the Company agreed not to enter into or be party to a Fundamental Transaction unless the successor entity in such transaction assumes in writing all of the Company’s obligations under the Series B Warrants, upon which the Series B Warrants shall become exercisable for shares of Common Stock, shares of the common

stock of the successor entity or the consideration that would have been issuable to the holders had they exercised the Series B Warrants prior to such Fundamental Transaction, at the holders’ election. Additionally, if the successor entity is a publicly traded corporation, the holders may elect to receive an equivalent security of the successor entity, in exchange for the Series B Warrants. Any security issuable or potentially issuable to the holder pursuant to the terms of the Series B Warrants on the consummation of a Fundamental Transaction must be registered and freely tradable by the holder without any restriction or limitation or the requirement to be subject to any holding period pursuant to any applicable securities laws.

The Series B Warrants also contain a "cashless exercise" feature that allows the holders to exercise the Series B Warrants without making a cash payment. The Series B Warrants are subject to a blocker provision which restricts the exercise of the Series B Warrants if, as a result of such exercise, the holder, together with its affiliates and any other person whose beneficial ownership of shares of Common Stock would be aggregated with the holder’s for purposes of Section 13(d) of the Exchange Act would beneficially own in excess of 4.99% or 9.99% of the outstanding shares of Common Stock (including the shares of Common Stock issuable upon such exercise), as such percentage ownership is determined in accordance with the terms of the Series B Warrants.

In the event that the Company does not have sufficient authorized shares to deliver in satisfaction of an exercise of a Series B Warrant, then unless the holder elects to void such attempted exercise, the holder may require the Company to pay an amount equal to the product of (i) the number of shares that the Company is unable to deliver and (ii) the highest volume-weighted average price of a share of Common Stock as quoted on the Nasdaq Capital Market during the period beginning on the date of such attempted exercise and ending on the date that the Company makes the applicable payment.

GTB-1550 (OXS-1550): Most Advanced Bi-specific ADC Candidate

The Company’s most advanced bi-specific ADC in development, GTB-1550, targets CD19+ and/or CD22+ hematological malignancies and is currently in the Phase 2 component of a Phase 1/2 Non-Hodgkin’s Lymphoma (NHL)/Acute Lymphocytic Leukemia (ALL) trial which is an open-label, investigator-led study.

GTB-1550 targets cancer cells expressing the CD19 receptor or CD22 receptor or both receptors. When GTB-1550 binds to cancer cells, the cancer cells internalize GTB-1550, and are killed due to the action of drug’s cytotoxic diphtheria toxin payload. GTB-1550 has demonstrated success in a Phase 1 human clinical trial in patients with relapsed/refractory B-cell lymphoma or leukemia.

Dr. Veronika Bachanova, Associate Professor of Medicine, Division of Hematology, Oncology and Transplantation at the University of Minnesota and the Principle Investigator for this study, is currently analyzing the final data and is anticipating submitting an abstract for the 2019 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) conference.

GTB-3550 (OXS-3550): TriKE product candidate

GTB-3550 is the Company’s first Tri-specific Killer Engager (TriKE) product candidate being initially developed for the treatment of acute myelogenous leukemia (AML). GTB-3550 is a single-chain, tri-specific scFv recombinant fusion protein conjugate composed of the variable regions of the heavy and light chains of anti-CD16 and anti-CD33 antibodies and a modified form of IL-15. When the NK stimulating cytokine human IL-15 is used as a crosslinker between the two scFvs, it provides a self-sustaining signal that activates NK cells and enhances their ability to kill.

GT Biopharma recently announced that its Investigational New Drug (IND) application to the U.S. Food and Drug Administration (FDA) is now open and it is authorized to initiate a first-in-human Phase 1 study with GTB-3550, its first-in-class TriKE, for the treatment of AML, myelodysplatic syndrome (MDS) and mastocytosis. The study will be led by Principal Investigator, Erica Warlick, Associate Professor, Division of Hematology, Oncology and Transplantation at Masonic Cancer Center, University of Minnesota.

This single center, first-in-human Phase 1 clinical trial of GTB-3550 will enroll up to 60 subjects with CD33-expressing refractory/relapsed AML, high-risk MDS, or advanced systemic mastocytosis. Subjects will receive a single course of GTB-3550 given as 3 weekly treatment blocks. Each block consists of four consecutive 24-hour continuous infusions of GTB-3550 followed by a 72-hour break after Block #1 and #2. Disease response will be assessed by bone marrow biopsy performed between Day 21 and Day 42 after the start of the 1st infusion. Follow-up for response and survival continues through 6 months from treatment start. The primary objective from the Phase 1 dose finding portion of the study will be to identify the maximum tolerated dose (MTD) of GTB-3550 defined as the dose level that most closely corresponds to a dose limiting toxicity rate (DLT) of 20%. The primary objective from the Phase 2 extended portion of the study will be the potential efficacy of GTB-3550, measured using rates of complete and partial remission. Subjects experiencing clinical benefit and no unacceptable side effects may be considered for a 2nd course of GTB-3550 on a compassionate basis.

The Company believes that GTB-3550 could serve as a relatively safe, cost-effective, and easy-to-use therapy for refractory/relapsed AML, high-risk MDS and advanced systemic mastocytosis and could also be combined with chemotherapy and/or other agents as frontline therapy thus targeting a much larger patient population.

GT Biopharma’s initial and ongoing work is being conducted in collaboration with the Masonic Cancer Center at the University of Minnesota under research agreements led by Dr. Jeffrey Miller, the Deputy Director and Dr. Daniel Vallera, Director, Section of Molecular Cancer Therapeutics.

GT Biopharma has an exclusive worldwide license agreement with the University of Minnesota to further develop and commercialize cancer therapies using proprietary TriKE technology developed by researchers at the university to target NK cells to cancer.
