March 2026 Security Promissory Note and Pledge Agreement

On March 13, 2026, Eshallgo Inc (the “Company”) issued a secured promissory note (the “March Promissory Note”) to a lender in the principal amount of $330,000 for a purchase price of $300,000. The Principal Amount includes an original issuance discount of $30,000.

The March Promissory Note bears interest at a fixed rate of 10% per annum and will mature in full on November 12, 2026. The Company may not voluntarily prepay any portion of the outstanding balance before the maturity date without the prior written consent of the lender. Furthermore, the March Promissory Note is subject to mandatory prepayments if the Company receives cash proceeds from any debt or equity financing, in which case the lender may require the Company to apply up to 100% of such proceeds toward the repayment of the March Promissory Note.

In connection with the March Promissory Note, on March 13, 2026, Zhidan Mao, the Company’s Chairman and director, and Qiwei Miao, the Company’s Chief Executive Officer and director (collectively, the “Pledgors”), entered into a pledge agreement (the “March Pledge Agreement”) with the lender. Pursuant to the March Pledge Agreement, the Pledgors collective pledged to the lender an aggregate of 1,126,154 Class B Ordinary Shares of the Company held by such Pledgors (collectively, the “March Pledged Shares”). The March Pledge Agreement secures all of the Company’s obligations under the March Promissory Note and grants the lender a continuing, first-priority security interest in the March Pledged Shares, including all associated substitutions, replacements, proceeds, and distributions, as well as all rights relating thereto. Upon the occurrence and continuance of certain events of default under the March Promissory Note, the lender is entitled to exercise customary secured party remedies with respect to the March Pledged Shares, subject to applicable notice and cure provisions.

The March Promissory Note contains customary representations and warranties, affirmative and restrictive covenants, and events of default. Upon the occurrence of certain events of default under the March Promissory Note, the interest rate on the outstanding balance automatically increases to 18%, subject to applicable notice and cure provisions.

April 2026 Security Promissory Note and Pledge Agreement

On April 4, 2026, the Company issued a secured promissory note (the “April Promissory Note”) to another lender in the principal amount of $300,000 for a purchase price of $300,000.

The April Promissory Note bears no interest and will mature in full on July 3, 2026. The Company may not voluntarily prepay any portion of the outstanding balance before the maturity date without the prior written consent of the lender. Furthermore, the April Promissory Note is subject to mandatory prepayments if the Company receives cash proceeds from any debt or equity financing, in which case the lender may require the Company to apply up to 100% of such proceeds toward the repayment of the April Promissory Note.

In connection with the April Promissory Note, on April 3, 2026, the Pledgors entered into a pledge agreement (the “April Pledge Agreement” and collectively with the March Pledge Agreement, the “Pledge Agreements”) with the lender. Pursuant to the April Pledge Agreement, the Pledgors collective pledged to the lender an aggregate of 1,126,154 Class B Ordinary Shares of the Company held by such Pledgors (collectively, the “April Pledged Shares”). The April Pledge Agreement secures all of the Company’s obligations under the April Promissory Note and grants the lender a continuing, first-priority security interest in the April Pledged Shares, including all associated substitutions, replacements, proceeds, and distributions, as well as all rights relating thereto. Upon the occurrence and continuance of certain events of default under the April Promissory Note, the lender is entitled to exercise customary secured party remedies with respect to the April Pledged Shares, subject to applicable notice and cure provisions.

The April Promissory Note contains customary representations and warranties, affirmative and restrictive covenants, and events of default.
