SECURED PROMISSORY NOTE

May 28, 2024

FOR VALUE RECEIVED, Invea Therapeutics, Inc., a Delaware corporation with a mailing address of 2614 Boston Post Road, Guilford, CT 06437, (“Borrower”) hereby unconditionally promises to pay to the order of Steven M. Burke, Esq., as Trustee of The Nandabalan 2020 Trust (the “Trust”) dated July 24, 2020, or its assigns (the “Holder”) the principal amount of three hundred and fifty thousand dollars ($350,000) (the “Loan”), together with all accrued interest thereon, as provided in this Secured Promissory Note (as same may be amended, restated, or otherwise modified from time to time in accordance with its terms, the “Note”).

1. Payment.

a. Payment Date. The aggregate unpaid principal amount of the Loan, all accrued and unpaid interest, and all other amounts payable under this Note shall be due and payable on November 27, 2024 (the “Maturity Date”). The Holder may, in Holder’s sole discretion, by written instrument extend the Maturity Date by one or more ninety (90) day increments. The Borrower agrees to make a lump sum payment of the principal balance of the Loan, all accrued and unpaid interest, and all other amounts payable under this Note on the Maturity Date.

b. Prepayment. The Borrower may prepay the Loan in whole or in part at any time or from time to time without penalty or premium by paying the principal amount to be prepaid together with accrued interest thereon to the date of prepayment.

2. Interest.

a. Interest Rate. Except as provided in Section 2(c), principal amounts outstanding under this Note shall bear interest of nine and one-half percent (9.5%) per annum (the “Interest Rate”) from the date the Loan was made until the Loan is paid in full, whether at maturity, upon acceleration, by prepayment, or otherwise.

b. Interest Payments. Each calendar year prior to and including the year in which the Maturity Date occurs, interest shall be payable on the earlier to occur of the Maturity Date and December 31.

c. Default Interest. If any amount payable hereunder is not paid when due, whether at stated maturity, by acceleration, or otherwise, such overdue amount shall bear interest at the Interest Rate plus five percent (5%) (the “Default Rate”).

d. Computation of Interest. All computations of interest hereunder shall be made on the basis of a year of 365/366 days, as the case may be, and the actual number of days elapsed. Interest shall begin to accrue on the Loan on the date of this Note. On any portion of the Loan that is repaid, interest shall not accrue on the date on which such payment is made.

3. Payment Mechanics.

a. Manner of Payment. All payments of principal and interest shall be made in US dollars on the date on which such payment is due. Such payments shall be made by check or wire transfer of immediately available funds to the Holder’s account at a bank specified by Holder in writing to the Borrower from time to time.

b. Application of Payments. All payments shall be applied, first, to fees or charges outstanding under this Note, second, to accrued interest, and, third, to principal outstanding under this Note.

c. Business Day. Whenever any payment hereunder is due on a day that is not a Business Day, such payment shall be made on the next succeeding Business Day, and interest shall be calculated to include such extension. “Business Day” means a day other than Saturday, Sunday, or other day on which commercial banks in Manchester, New Hampshire are authorized or required by law to close.

4. Power and Authority; No Approvals; No Violations; Enforceability.

6. Notice of Event of Default. As soon as possible after it becomes aware that an Event of Default has occurred, and in any event within two (2) Business Days, the Borrower shall notify the Holder in writing of the nature and extent of such Event of Default and the action, if any, it has taken or proposes to take with respect to such Event of Default.

7. Remedies. Upon the occurrence and during the continuance of an Event of Default, the Holder may, at their option, by written notice to the Borrower declare the outstanding principal amount of the Loan, accrued and unpaid interest thereon, and all other amounts payable hereunder immediately due and payable; provided, however, if an Event of Default described in Sections 5(c)(i) and 5(c)(iii) shall occur, the outstanding principal amount, accrued and unpaid interest, and all other amounts payable hereunder shall become immediately due and payable without notice, declaration, or other act on the part of the Holder.

20. Security Interest. The Borrower hereby grants to Holder (the “Secured Party”), to secure the payment and performance in full of all of all amounts due pursuant to this Note, a continuing security interest in, and pledges to the Secured Party, the collateral described on Exhibit A hereto (the “Collateral”), and hereby authorizes the Secured Party to file financing statements or take any other action reasonably determined by the Secured Party to be required to perfect the Secured Party’s security interests in the Collateral, without notice to the Borrower, with all appropriate jurisdictions to perfect or protect the Secured Party’s interest or rights under the Note. During the existence of any Event of Default, the Secured Party may exercise all rights and remedies of a secured party under the Uniform Commercial Code, as the same may, from time to time, be enacted and in effect in the State of Delaware (the “UCC”).
