Exhibit 10.10

APIMEDS PHARMACEUTICALS US, INC.

Promissory Note

FOR VALUE RECEIVED, APIMEDS PHARMACEUTICALS US, INC., a Delaware limited liability company (“Maker”), promises to pay to the order of INSCOBEE, INC., a South Korean company (“Payee”), at such place as Payee may from time to time designate, the principal sum of ONE HUNDRED THOUSAND DOLLARS ($100,000.00) (the “Loan”), together with interest on the unpaid principal balance outstanding from time to time, all as hereinafter set forth. Payments of both principal and interest shall be paid in lawful money of the United States of America, which shall be legal tender in payment of all debts and dues.

1. Use of Loan Proceeds. The proceeds of the Loan shall be used by Maker for repayment of outstanding fees and expenses and other general working capital purposes.

2. Interest. Interest on the outstanding principal balance of the Loan shall accrue at a rate equal to five percent (5%) per annum (the “Interest Rate”) and shall be computed on the actual number of days outstanding based on a three hundred sixty-five (365) day year. Interest on the outstanding principal balance of the Loan shall accrue and be payable on the Maturity Date (as defined below).

3. Loan Term. The entire outstanding principal balance of and all accrued and unpaid interest thereon shall be due upon the earlier of (i) the closing of an equity financing by Maker with gross proceeds to the Company of at least $3,000,000 (the “Closing Date”); and (ii) July 15, 2022 (the earlier of such dates, the “Maturity Date”). In the event the Maturity Date is the Closing Date, within five (5) business days following the Closing Date, any outstanding principal balance of the Loan not previously used by Maker shall be paid to Payee, and the remaining outstanding principal balance of the Loan, together with all accrued and unpaid interest on the principal balance of the Loan up to and including the Closing Date, shall be paid to Payee in four (4) equal monthly installments commencing on the date which is thirty (30) days following the Closing. In the event July 15, 2022 is the Maturity Date, a single payment for the entire outstanding principal balance of the Loan, together with all accrued and unpaid interest thereon, shall be due and payable on the Maturity Date.

4. Prepayment. This Promissory Note (this “Note”) may be prepaid, without penalty or premium, which consent shall not be unreasonably withheld, delayed or conditioned. Any prepayment shall be accompanied by payment of all unpaid late payment penalties, if any, which are due plus all accrued and unpaid interest due as of the date of such prepayment. All partial prepayments of principal shall be applied to any principal installment payments in the inverse order of their maturity.

5. Events of Default; Acceleration. If any payment due hereunder is not paid within five (5) days after the date that the amount was due, a default interest rate of the Interest Rate plus five percent (5%) shall be assessed against the defaulted payment (and any future defaults) until such payment (and any future defaulted payments) is made in full to Payee. In addition, Payee, in Payee’s sole discretion and without notice or demand, may declare the entire unpaid principal balance plus accrued interest and all other sums due hereunder immediately due and payable. Failure by Payee to exercise this option shall not constitute a waiver of the right to exercise the same in the event of any subsequent default. Notwithstanding any other provision contained herein, if, at any time, any rate of interest charged under this Note shall be deemed by any competent court of law, governmental agency or tribunal to exceed the maximum rate of interest permitted by any applicable law, for such time as such rate of interest would be deemed excessive, its application shall be suspended and there shall be charged instead the maximum rate of interest permitted under such laws.

6. Costs and Expenses; Waiver by Maker. Maker shall pay to Payee and reimburse Payee for any and all costs and expenses, including attorney’s fees and court costs, if any, incurred by Payee to enforce or collect this Note. Maker waives presentment, protest and demand, notice of protest, notice of dishonor and nonpayment of this Note and expressly agrees that this Note or any payment hereunder may be extended from time to time without in any way affecting the liability of any Maker hereunder.

7. Cumulative Remedies; No Waiver by Payee. The rights and remedies of Payee hereunder shall be cumulative and concurrent and may be pursued singularly, successively or together at the sole discretion of Payee, and may be exercised as often as occasion therefor shall occur, and the failure to exercise any such right or remedy shall in no event be construed as a waiver or release of the same or any other right or remedy.

8. Evidence of Indebtedness. This Note is given and accepted as evidence of indebtedness only, and not in payment or satisfaction of any indebtedness or obligation.

9. Headings. The headings used in this Note are for convenience only and are not to be interpreted as a part of this Note.
