These conversions resulted in a reclassification within stockholders' equity (deficit) with no income statement impact.

The SAFE includes a post-money valuation cap of $7,500,000. Capitalized words used but not defined herein shall have the meaning as set forth in the SAFE.

If there is a Liquidity Event before the termination of the SAFE, the Company will automatically be entitled to receive a portion of Proceeds equal to the greater of (i) the Purchase Amount or (ii) the amount payable on the number of shares of Common Stock equal to the Purchase Amount divided by the Liquidity Price. If there is a Dissolution Event before the termination of the SAFE, the Company will automatically be entitled to receive a portion of Proceeds equal to the Purchase Amount, subject to the liquidation priority provisions set forth in the SAFE. The SAFE is not transferable or assignable by either party without the prior written consent of the other, subject to certain customary exceptions.
