DiamiR
issued 44,000 restricted stock units (“RSUs”) in the fiscal year ending May 31, 2023 as consideration for consulting services
received from third parties, subject to certain vesting conditions. No compensation expense related to the RSUs was recognized in the
years ended May 31, 2024 or May 31, 2023, as the vesting condition was not considered to be probable of achievement for accounting purposes.
On August 31, 2023, the 44,000 RSUs were canceled.

DiamiR
also issued 140,000 options as consideration for consulting services received from third parties in the fiscal years ending May 31, 2023,
subject to certain vesting conditions. In the year ended May 31, 2024, the 140,000 options were canceled and in their place 153,000 options
were issued with amended terms, of which 58,500 options were subsequently forfeited.

DiamiR
issued 88,000 RSUs and 154,000 stock options in the fiscal year ending May 31, 2023 to our CEO as compensation for services, subject to
certain vesting conditions. No compensation expense related to these awards was recognized in the years ended May 31, 2024 or May 31,
2023, as the vesting conditions were not considered to be probable of achievement for accounting purposes.

As
of May 31, 2024, unrecognized stock-based compensation expense related to awards for which vesting is not considered probable was $1,093,712.
As of February 28, 2025, unrecognized stock-based compensation expense related to restricted stock units for which vesting is not considered
probable was $652,080. This compensation expense will be recognized in future periods if DiamiR determines the vesting conditions have
become probable.
