 than the consideration to be
received by Aptorum pursuant to the Merger Agreement.

If the conditions to the Merger Agreement are not met, the Merger will not occur.

Even if the Merger is approved
by the shareholders of Aptorum and DiamiR, specified conditions must be satisfied or waived to complete the Merger. These conditions are
set forth in the Merger Agreement. Aptorum and DiamiR cannot assure you that all of the conditions will be satisfied. If the conditions
are not satisfied or waived, the Merger will not occur or will be delayed, and Aptorum and DiamiR each may lose some or all of the intended
benefits of the Merger.

Some Aptorum and DiamiR officers and directors have interests in the Merger that are different from yours and that may influence them to support or approve the Merger without regard to your interests.

Certain officers and directors
of Aptorum and DiamiR participate in arrangements that provide them with interests in the Merger that are different from yours, including,
among others, the continued service as an officer or director of the Combined Company, continued indemnification and the potential ability
to sell an increased number of shares of the Combined Company in accordance with Rule 144 under the Securities Act. These interests,
among others, may influence the officers and directors of Aptorum and DiamiR to support or approve the Merger.

No fairness opinion was obtained in connection with the Merger.

In connection with determination
of consideration of the Merger, Aptorum did not request any independent investment banker or other professional to provide a fairness
opinion. The consideration to be received by the holders of DiamiR securities in the Merger was reached through negotiation by Aptorum
and DiamiR, and was found to be fair to the stockholders of Aptorum by Aptorum’s board of directors. In determining whether to obtain
a fairness opinion in connection with consideration of the merger, Aptorum’s board considered the cost of such an opinion as well
as, among other factors, the extensive negotiations with DiamiR by Aptorum and DiamiR, the board’s assessment of the prospects for
DiamiR based on its evaluation of its intellectual property and the valuation of DiamiR implicit in its prior financings, when compared
to and in light of Aptorum’s current market value and its financial position.
