Rising Dragon Acquisition Corp., a Cayman Islands exempted company (the "**Maker**"), promises to pay to the order of SZG Limited or its assignees or successors in interest (the "**Payee**") the principal sum of Fifty Thousand U.S. Dollars (US$50,000) in lawful money of the United States of America, on the terms and conditions described below. All payments on this Note shall be made by check or wire transfer of immediately available funds or as otherwise agreed by the Maker and the Payee to such account as the Payee may from time to time designate by written notice in accordance with the provisions of this Note.

**1.** **Principal.** The principal balance of this Promissory Note (this "**Note**") shall be payable on the date on which
the contemplated initial business combination (the "**Business Combination**") with a target business (as described in
its initial public offering prospectus dated October 10, 2024 (the "**Prospectus** ")). In the event that the Maker terminates
the merger agreement with the Payee and certain other parties dated on January 27, 2025 (the "**Merger Agreement**") under
section 13.2(a) of the Merger Agreement, this Note shall be deemed to be terminated and no amounts will thereafter be due from the Maker
to the Payee under the terms hereof. In the event that a Business Combination does not close prior to the Closing Date (as defined in
the Merger Agreement) due to reasons not attributable to the Maker or the Merger Agreement is terminated mutually by the parties to the
Merger Agreement, this Note shall be deemed to be terminated and no amounts will thereafter be due from the Maker to the Payee under the
terms hereof.

**2.** **Conversion Rights**. The Payee has the right, but not the obligation, to convert this Note, in whole
or in part, into private units (the "**Units**") of the Maker (as described in the Prospectus), by providing the Maker
with written notice of its intention to convert this note at least five (5) business days prior to the closing of a Business Combination.
The number of Units to be received by the Payee in connection with such conversion shall be an amount determined by dividing (x) the sum
of the outstanding principal amount payable to such Payee by (y) US$10.00.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) **Fractional Shares**. No fractional Units will be issued
upon conversion of this Note. In lieu of any fractional Units to which Payee would otherwise be entitled, Maker will pay to Payee in
cash the amount of the unconverted principal balance of this note that would otherwise be converted into such fractional share.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) **Effect of Conversion**. If the Maker timely receives notice
of the Payee's intention to convert this note at least five (5) business days prior to the closing of a Business Combination, this
Note shall be deemed to be converted on the date the Business Combination closes. At its expense, the Maker will, as soon as practicable
after receiving this Note for cancellation after the closing of a Business Combination (assuming receipt of timely notice of conversion),
issue and deliver to Payee, at Payee's address set forth on the signature page hereto or such other address requested by Payee,
a certificate or certificates for the number of Units to which Payee is entitled upon such conversion (bearing such legends as are customary
pursuant to applicable state and federal securities laws), including a check payable to Payee for any cash amounts payable as a result
of any fractional shares as described herein.

**3.** **Use of Proceeds.** Maker shall use the proceeds received under this Note to extend the time available
for the Maker to consummate a Business Combination. The proceeds received under this Note must be deposited into the trust account (the
" **Trust Account**") described in the Prospectus.

**4.** **Interest.** No interest shall accrue on the unpaid principal balance of this Note.

**5.** **Application of Payments.** All payments shall be applied first to payment in full of any costs incurred
in the collection of any sum due under this Note, including (without limitation) reasonable attorney's fees, then to the payment
in full of any late charges and finally to the reduction of the unpaid principal balance of this Note.

**6.** **Events of Default**. The following shall constitute an event of default ()"**Event of Default** "):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) **Failure to Make Required Payments.** Failure by Maker to pay the principal of this Note within
five (5) business days following the date when due.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) **Voluntary Liquidation, Etc.** The commencement by Maker of a proceeding relating to its bankruptcy,
insolvency, reorganization, rehabilitation or other similar action, or the consent by it to the appointment of, or taking possession by,
a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar official) for Maker or for any substantial part of
its property, or the making by it of any assignment for the benefit of creditors, or the failure of Maker generally to pay its debts as
such debts become due, or the taking of corporate action by Maker in furtherance of any of the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) **Involuntary Bankruptcy, Etc.** The entry of a decree or order for relief by a court having jurisdiction
in the premises in respect of maker in an involuntary case under any applicable bankruptcy, insolvency or similar law, for the appointing
of a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) for Maker or for any substantial part of its
property, or ordering the winding-up or liquidation of the affairs of Maker, and the continuance of any such decree or order unstayed
and in effect for a period of 60 consecutive days.

**7.** **Remedies**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Upon the occurrence of an Event of Default specified in Section 6(a) hereof, Payee may, by written notice
to Maker, declare this Note to be due immediately and payable, whereupon the unpaid principal amount of this Note, and all other amounts
payable hereunder, shall become immediately due and payable without presentment, demand, protest or other notice of any kind, all of which
are hereby expressly waived, anything contained herein or in the documents evidencing the same to the contrary notwithstanding.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Upon the occurrence of an Event of Default specified in Sections 6(b) and 6(c), the unpaid principal balance

modification granted or consented to by Payee, and consents to any and all extensions of time, renewals, waivers, or modifications that
may be granted by Payee with respect to the payment or other provisions of this Note, and agrees that additional makers, endorsers, guarantors,
or sureties may become parties hereto without notice to the Maker or affecting Maker's liability hereunder.
