Accordingly, and as a result of their ownership, these two shareholders of DiamiR currently control substantially all matters requiring
approval by DiamiR’s stockholders, including the election of all directors and approval of significant corporate transactions. This
could make it impossible for other stockholders to influence the affairs of DiamiR and could delay or prevent an outside party from acquiring
or merging with DiamiR even if its other shareholders wanted it to occur. This concentration of ownership may also have the effect of
delaying or preventing a change of control of DiamiR or discouraging others from making tender offers for its shares, which could prevent
its stockholders from receiving a premium for its shares. Some of these persons or entities who make up DiamiR’s principal stockholders
may have interests different from other shareholders of DiamiR.

DiamiR’s information technology systems or data, or those of DiamiR’s service providers or customers or users could be subject to cyber-attacks or other security incidents, which could result in data breaches, intellectual property theft, claims, litigation, regulatory investigations, significant liability, reputational damage and other adverse consequences.

DiamiR continues to expand its information technology (or IT) systems
as its operations grow, such as product data management, procurement, inventory management, production planning and execution, sales,
service and logistics, dealer management, financial, tax and regulatory compliance systems. This includes the implementation of new internally
developed systems and the deployment of such systems in the U.S. and abroad. While, DiamiR maintains information technology measures designed
to protect it against intellectual property theft, data breaches, sabotage and other external or internal cyber-attacks or misappropriation,
its systems and those of their service providers are potentially vulnerable to malware, ransomware, viruses, denial-of-service attacks,
phishing attacks, social engineering, computer hacking, unauthorized access, exploitation of bugs, defects and vulnerabilities, breakdowns,
damage, interruptions, system malfunctions, power outages, terrorism, acts of vandalism, security breaches, security incidents, inadvertent
or intentional actions by employees or other third parties, and other cyber-attacks.

To the extent any security incident results in unauthorized access
or damage to or acquisition, use, corruption, loss, destruction, alteration or dissemination of DiamiR’s data, including intellectual
property and personal information, or
