 DiamiR’s products, or for it to be believed or reported that any of these occurred, it could
disrupt DiamiR’s business, harm its reputation, compel it to comply with applicable data breach notification laws, subject it to
time consuming, distracting and expensive litigation, regulatory investigation and oversight, mandatory corrective action, require it
to verify the correctness of database contents, or otherwise subject it to liability under laws, regulations and contractual obligations,
including those that protect the privacy and security of personal information. This could result in increased costs to DiamiR and result
in significant legal and financial exposure and/or reputational harm.

DiamiR also relies on service providers, and similar incidents relating
to their information technology systems could also have a material adverse effect on DaimiR’s business. There have been and may
continue to be significant supply chain attacks. DiamiR’s service providers, including its workforce management software provider,
have been subject to ransomware and other security incidents, and DiamiR cannot guarantee that it or its service providers’ systems
have not been breached or that they do not contain exploitable defects, bugs, or vulnerabilities that could result in a security incident,
or other disruption to, it or its service providers’ systems. DiamiR’s ability to monitor its service providers’ security
measures is limited, and, in any event, malicious third parties may be able to circumvent those security measures.

Further, the implementation, maintenance, segregation and improvement
of these systems require significant management time, support and cost, and there are inherent risks associated with developing, improving
and expanding its core systems as well as implementing new systems and updating current systems, including disruptions to the related
areas of business operation. These risks may affect DaimiR’s ability to manage its data and inventory, procure parts or supplies
or manufacture, sell, deliver and service products, adequately protect its intellectual property or achieve and maintain compliance with,
or realize available benefits under, tax laws and other applicable regulations.

Moreover, if DiamiR does not successfully implement, maintain or expand
these systems as planned, DiamiR’s operations may be disrupted, its ability to accurately and/or timely report its financial results
could be impaired and deficiencies may arise in the Combined Company’s internal control over financial reporting, which may impact
the Combined Company’s ability to certify its financial results. Moreover, DiamiR’s proprietary information, including intellectual
property and personal information, could
