Attn: Dingxin Sun, Chairman of the Board

Dear Mr. Sun:

This letter (the “Agreement”) constitutes the agreement between D. Boral Capital LLC (the “Placement Agent”) and Decent Holding Inc., an exempted company incorporated in the Cayman Islands with limited liability (collectively with its subsidiaries, the “Company”), that the Placement Agent shall serve as the exclusive placement agent for the Company, on a reasonable “best efforts” basis, in connection with the proposed offering (the “Placement”) of units (the “Units”), with each Unit consisting of (i) one (1) Class A ordinary share of the Company, par value US$0.0001 per share (the “Class A Ordinary Shares”), and (ii) two (2) warrants, each to purchase one Class A Ordinary Share (the “Warrants”, together with the Class A Ordinary Shares, the “Securities”). The Securities actually placed by the Placement Agent in the Placement are referred to herein as the “Placement Securities.” The Class A Ordinary Shares, the Warrants, and the Class A Ordinary Shares underlying the Warrants will be offered and sold under the Company’s registration statement on Form F-1 (File No. 333-[         ]) (the “Registration Statement”), with the terms of the Placement to be subject to market conditions and negotiations among the Company, the Placement Agent and the Purchasers. The documents executed and delivered by the Company and the Purchasers (as defined below) in connection with the Placement, including, without limitation, a securities purchase agreement (the “Purchase Agreement”), are collectively referred to herein as the “Transaction Documents.”

The terms of the Placement are to be mutually agreed upon by the Company and purchasers signatories to the Purchase Agreement (each, a “Purchaser” and collectively, the “Purchasers”), and nothing herein confers upon the Placement Agent the power or authority to bind the Company or any Purchaser, or constitutes an obligation for the Company to issue any Placement Securities or complete the Placement. The Company expressly acknowledges and agrees that the Placement Agent’s obligations hereunder are on a best efforts basis only and that the execution of this Agreement does not constitute a commitment by the Placement Agent to purchase the Securities and does not ensure the successful placement of the Securities, or any portion thereof, or the success of the Placement Agent with respect to securing any other financing on behalf of the Company. The Placement Agent may retain other brokers or dealers to act as sub-agents or selected-dealers on its behalf in connection with the Placement. Certain affiliates of the Placement Agent may participate in the Placement by purchasing some of the Securities. The sale of Placement Securities to any Purchaser will be evidenced by a Purchase Agreement between the Company and such Purchaser in a form reasonably acceptable to the Company and the Purchaser. Capitalized terms that are not otherwise defined herein have the meanings given to such terms in the Purchase Agreement. Prior to the signing of any Purchase Agreement, officers of the Company will be available to answer inquiries from prospective Purchasers.

Section 1. Representations and Warranties of the Company; Covenants of the Company.

(a) Representations of the Company. With respect to the Placement Securities, each of the representations and warranties (together with any related disclosure schedules thereto) and covenants made by the Company to the Purchasers in the Purchase Agreement in connection with the Placement, is hereby incorporated herein by reference into this Agreement (as though fully restated herein) and is, as of the date of this Agreement and as of the date of the closing of the Placement (the “Closing Date”), hereby made to, and in favor of, the Placement Agent. In addition to the foregoing, the Company represents and warrants that there are no affiliations with any Financial Industry Regulatory Authority, Inc.

ANNEX A: INDEMNIFICATION

The Company agrees to indemnify and hold harmless the Placement Agent and its affiliates and their respective present and former directors, officers, employees, agents and controlling persons (each such person, including the Placement Agent, an “Indemnified Party”) from and against any losses, claims, damages and liabilities, joint or several (collectively, “Damages”), to which such Indemnified Party may become subject in connection with, relating to or arising from any transaction contemplated by this Agreement or the engagement of or performance of services by an Indemnified Party hereunder, and will reimburse each Indemnified Party for all out-of-pocket fees and expenses (“Expenses”), including the reasonable fees and expenses of counsel, as they are incurred in connection with investigating, preparing, pursuing or defending any threatened or pending subpoena, claim, action, proceeding or investigation (“Proceedings”) arising therefrom, whether or not any Indemnified Party is a formal party to such Proceeding; provided, that the Company will not be liable to any Indemnified Party to the extent that any Damages are found in a final non-appealable judgment by a court of competent jurisdiction to have resulted solely from the bad faith, gross negligence or willful misconduct of the Indemnified Party. No Indemnified Party will have any liability (whether direct or indirect, in contract, tort or otherwise) to the Company or any person asserting claims on behalf of the Company arising out of or in connection with any transactions contemplated by this Agreement or the engagement of or performance of services by any Indemnified Party hereunder except to the extent that the Company incurs Damages that are found in a final non-appealable judgment by a court of competent jurisdiction to have resulted solely from the bad faith, gross negligence or willful misconduct of the Indemnified Party.

If for any reason other than in accordance with the previous paragraph of this Annex A, the foregoing indemnity is unavailable to an Indemnified Party or insufficient to hold an Indemnified Party harmless, then the Company will contribute to the amount paid or payable by an Indemnified Party for Damages and Expenses related thereto in such proportion as is appropriate to reflect the relative benefits to the Company and/or its shareholders on the one hand, and the Placement Agent on the other hand, in connection with the matters covered by this Agreement or, if the foregoing allocation is not permitted by applicable law, not only such relative benefits but also the relative faults of such parties as well as any relevant equitable considerations. The Company agrees that for purposes of this paragraph the relative benefits to the Company and/or its shareholders and the Placement Agent in connection with the matters covered by this Agreement will be deemed to be in the same proportion that the total value paid or received or to be paid or received by the Company and/or its shareholders in connection with the transactions contemplated by this Agreement, whether or not consummated, bears to the fees paid to the Placement Agent under this Agreement; provided, that in no event will the total contribution of all Indemnified Parties to all such Damages and Expenses exceed the amount of fees actually received and retained by the Placement Agent under this Agreement (excluding any amounts received by the Placement Agent as reimbursement of expenses). Relative fault shall be determined by reference to, among other things, whether any alleged untrue statement or omission or any alleged conduct relates to information provided by the Company or other conduct by the Company (or its employees or other agents) on the one hand, or by the Placement Agent, on the other hand.

No Indemnified Party will agree to settle any Proceeding and seek indemnification or reimbursement hereunder unless such Indemnified Party obtained the Company’s consent (which consent will not be unreasonably withheld) to such settlement. The Company agrees not to enter into any waiver, release or settlement of any Proceeding (whether or not any Indemnified Party is a party thereto) in respect of which indemnification may be sought hereunder without the prior written consent of the Placement Agent (which consent will not be unreasonably withheld), unless such waiver, release or settlement (i) includes an unconditional release of each Indemnified Party from all liability arising out of such Proceeding, (ii) does not contain any factual or legal admission by or with respect to any Indemnified Party or any adverse statement with respect to the character, professionalism, expertise or reputation of any Indemnified Party or any action or inaction of any Indemnified Party and (iii) does not preclude or purport to preclude the future business activities of any Indemnified Person.

In addition to any rights of indemnification or contribution set forth above, the Company agrees to reimburse each Indemnified Party for all out-of-pocket costs and expenses as they are incurred (including, without limitation, the reasonable fees and expenses of outside counsel) in connection with investigating, preparing or settling any Proceeding involving the enforcement of this Agreement or this Annex A.

The indemnity, reimbursement and contribution obligations of the Company are in addition to any liability that the Company may have at common law or otherwise to any Indemnified Party and will be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Company or an Indemnified Party. The provisions of this Annex will survive the modification, expiration or termination of this Agreement.
