 Cayman Islands 
 Re: Securities Subscription
Agreement 
 Ladies and Gentlemen: 

Constellation Acquisition Company, a Cayman Islands exempted company (the “Company” or “us”), is pleased to
accept the offer of Decent Group Co. Ltd, a Cayman Islands exempted company (the “Subscriber” or “you”), to purchase 2,875,000 shares of Class B ordinary shares (the “Shares”), par value
$0.0001 per share (the “Class B Ordinary Shares” and, together with all other classes of Company ordinary shares, the “Ordinary Shares”), of which up to 375,000 Shares are subject to complete or
partial forfeiture by you if the underwriters of the initial public offering (“IPO”) of the Company do not fully exercise their over-allotment option (the “Over-allotment Option”). The terms of this letter agreement
(this “Agreement”) on which the Company is willing to sell, and the Subscriber is willing to purchase, the Shares, and the Company and the Subscriber’s agreements regarding such Shares, are as follows: 

 

	1.	 Purchase of Shares. For the sum of $25,000, which the Company acknowledges receiving in cash, the
Company hereby sells and issues the Shares to the Subscriber, and the Subscriber hereby purchases the Shares from the Company, subject to the forfeiture provisions of Section 3 below, on the terms and subject to the
conditions set forth in this Agreement. Concurrently with the Subscriber’s execution of this Agreement, the Company shall register the Shares in the name of the Subscriber on the register of members of the Company. All references in this
Agreement to shares of the Company being forfeited shall take effect as surrenders for no consideration of such shares as a matter of Cayman Islands law. The Subscriber surrenders for no consideration the one Ordinary Share of the Company currently
held by it following the incorporation of the Company. 


  

	2.	 Representations, Warranties and Agreements. 



 

	 	2.1.	 Subscriber’s Representations, Warranties and Agreements. To induce the Company to issue the Shares
to the Subscriber, the Subscriber hereby represents and warrants to the Company and agrees with the Company as follows: 


  

	 	2.1.1.	 No Government Recommendation or Approval. The Subscriber understands that no federal or state agency has
passed upon or made any recommendation or endorsement of the offering of the Shares. 


  

	 	2.1.2.	 No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the
Subscriber of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the formation and governing documents of the Subscriber, (ii) any agreement, indenture or instrument to which the Subscriber
is a party, (iii) any law, statute, rule or regulation to which the Subscriber is subject, or (iv) any agreement, order, judgment or decree to which the Subscriber is subject. 



 

	 	2.1.3.	 Organization and Authority. The Subscriber is a Cayman Islands exempted company, validly existing and in
good standing under the laws of the Cayman Islands and possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement. Upon execution and delivery by you, this Agreement will be a legal, valid and
binding agreement of Subscriber, enforceable against Subscriber in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar laws affecting the enforcement of
creditors’ rights generally and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity). 















	 	2.1.4.	 Experience, Financial Capability and Suitability. Subscriber is: (i) sophisticated in financial
matters and is able to evaluate the risks and benefits of the investment in the Shares and (ii) able to bear the economic risk of its investment in the Shares for an indefinite period of time because the Shares have not been registered under
the Securities Act of 1933, as amended (the “Securities Act”), and therefore cannot be resold unless subsequently registered under the Securities Act or an exemption from such registration is available. Subscriber is capable of
evaluating the merits and risks of its investment in the Company and has the capacity to protect its own interests. Subscriber must bear the economic risk of this investment until the Shares are sold pursuant to: (x) an effective registration
statement under the Securities Act or (y) an exemption from registration available with respect to such sale. Subscriber is able to bear the economic risks of an investment in the Shares and can afford a complete loss of Subscriber’s
investment in the Shares. 


  

	 	2.1.5.	 Access to Information; Independent Investigation. Prior to the execution of this Agreement, the
Subscriber has had the opportunity to ask questions of and receive answers from representatives of the Company concerning an investment in the Company, as well as the finances, operations, business and prospects of the Company, and the opportunity
to obtain additional information to verify the accuracy of all information so obtained. In determining whether to make this investment, Subscriber has relied solely on Subscriber’s own knowledge and understanding of the Company and its business
based upon Subscriber’s own due diligence investigation and the information furnished pursuant to this paragraph. Subscriber understands that no person has been authorized to give any information or to make any representations which were not
furnished pursuant to this Section 2, and Subscriber has not relied on any other representations or information in making its investment decision, whether written or oral, relating to the Company, its operations and/or its
prospects. 


  

	 	2.1.6.	 Regulation D Offering. Subscriber represents that it is an “accredited investor” as such term
is defined in Rule 501(a) of Regulation D under the Securities Act, and acknowledges the sale contemplated hereby is being made in reliance on a private placement exemption applicable to “accredited investors” within the meaning of
Section 501(a) of Regulation D under the Securities Act or similar exemptions under federal and state law. 


  

	 	2.1.7.	 Investment Purposes. The Subscriber is purchasing the Shares solely for investment purposes, for the
Subscriber’s own account and not for the account or benefit of any other person, and not with a view towards the distribution or dissemination thereof. The Subscriber did not enter into this Agreement as a result of any general solicitation or
general advertising within the meaning of Rule 502 of Regulation D under the Securities Act. 


  

	 	2.1.8.	 Restrictions on Transfer; Shell Company. Subscriber understands the Shares are being offered in a
transaction not involving a public offering within the meaning of the Securities Act. Subscriber understands the Shares will be “restricted securities” as defined in Rule 144(a)(3) under the Securities Act, and Subscriber understands that
the certificates or book-entries representing the Shares will contain a legend in respect of such restrictions. If in the future the Subscriber decides to offer, resell, pledge or otherwise transfer the Shares, such Shares may be offered, resold,
pledged or otherwise transferred only pursuant to: (i) registration under the Securities Act, or (ii) an available exemption from registration. Subscriber agrees that if any transfer of its Shares or any interest therein is proposed to be
made, as a condition precedent to any such transfer, Subscriber may be required to deliver to the Company an opinion of counsel satisfactory to the Company. Absent registration or an exemption, the Subscriber agrees not to resell the Shares.
Subscriber further acknowledges that because the Company is a shell company, Rule 144 may not be available to the Subscriber for the resale of the Shares until one year following consummation of the initial business combination of the Company,
despite technical compliance with the requirements of Rule 144 and the release or waiver of any contractual transfer restrictions. 


  

	 	2.1.9.	 No Governmental Consents. No governmental, administrative or other third party consents or approvals are
required, necessary or appropriate on the part of Subscriber in connection with the transactions contemplated by this Agreement. 















	 	2.2.	 Company’s Representations, Warranties and Agreements. To induce the Subscriber to purchase the
Shares, the Company hereby represents and warrants to the Subscriber and agrees with the Subscriber as follows: 


  

	 	2.2.1.	 Organization and Corporate Power. The Company is a Cayman Islands exempted company and is qualified to
do business in every jurisdiction in which the failure to so qualify would reasonably be expected to have a material adverse effect on the financial condition, operating results or assets of the Company. The Company possesses all requisite corporate
power and authority necessary to carry out the transactions contemplated by this Agreement. 


  

	 	2.2.2.	 No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the
Company of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the Company’s Memorandum and Articles of Association, as amended to the date hereof (the “Memorandum and Articles”),
(ii) any agreement, indenture or instrument to which the Company is a party, (iii) any law, statute, rule or regulation to which the Company is subject, or (iv) any agreement, order, judgment or decree to which the Company is subject.



  

	 	2.2.3.	 Title to Securities. Upon issuance in accordance with, and payment pursuant to, the terms hereof and the
Memorandum and Articles, and registration in the register of members of the Company, the Shares will be duly and validly issued as fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof and the
Memorandum and Articles, the Subscriber will have or receive good title to the Shares, free and clear of all liens, claims and encumbrances of any kind, other than (a) transfer restrictions hereunder and under the other agreements to which the
Shares may be subject which have been notified to the Subscriber in writing, (b) transfer restrictions under federal and state securities laws, and (c) liens, claims or encumbrances imposed due to the actions of the Subscriber.



  

	 	2.2.4.	 No Adverse Actions. There are no actions, suits, investigations or proceedings pending, threatened
against or affecting the Company which: (i) seek to restrain, enjoin, prevent the consummation of or otherwise affect the transactions contemplated by this Agreement or (ii) question the validity or legality of any transactions or seek to
recover damages or to obtain other relief in connection with any transactions. 


  

	 	2.2.5.	 Authorization. The Class A Ordinary Shares issuable upon conversion of the Class B Ordinary
Shares have been duly authorized and reserved for issuance upon such conversion. 


  

	3.	 Forfeiture of Shares. 



 

	 	3.1.	 Partial or No Exercise of the Over-allotment Option. In the event the Over-allotment Option granted to
the underwriters of the IPO is not exercised in full, the Subscriber acknowledges and agrees that it (or, if applicable, it and any transferees of Shares) shall forfeit any and all rights to such number of Shares (up to an aggregate of 375,000
Shares and pro rata based upon the percentage of the Over-allotment Option exercised) such that immediately following such forfeiture, the Subscriber (and any such transferees) will own an aggregate number of Shares (not including any private
placement shares, warrants, rights or units that may be purchased prior to or at the closing of the IPO, Shares issuable upon exercise of any warrants or rights or any Ordinary Shares, warrants, rights or units purchased by Subscriber in the IPO or
in the aftermarket) equal to 20% of the issued and outstanding Ordinary Shares immediately following the IPO (in each case, not including Class A Ordinary Shares issuable upon exercise of any warrants). 



 

	 	3.2.	 Termination of Rights as Shareholder. If any of the Shares are forfeited in accordance with this
Section 3, then after such time, the Subscriber (or successor in interest) shall no longer have any rights as a holder of such forfeited Shares, and the Company shall take such action as is appropriate to cancel such
forfeited Shares. 















	4.	 Waiver of Liquidation Distributions; Redemption Rights. With respect to the Shares purchased pursuant to
this Agreement, the Subscriber hereby waives any and all right, title, interest or claim of any kind in or to any distributions by the Company from the trust account which will be established for the benefit of the Company’s public shareholders
and into which substantially all of the proceeds of the IPO will be deposited (the “Trust Account”), in the event of a liquidation of the Company upon the Company’s failure to timely complete an initial business combination.
For purposes of clarity, in the event the Subscriber purchases Ordinary Shares in the IPO or in the aftermarket, any additional Ordinary Shares so purchased shall be eligible to receive any liquidating distributions by the Company. However, in no
event will the Subscriber have the right to redeem any Shares into funds held in the Trust Account upon the successful completion of an initial business combination. 



 

	5.	 Restrictions on Transfer. 



 

	 	5.1.	 Securities Law Restrictions. In addition to any restrictions to be contained in that certain letter
agreement (commonly known as an “Insider Letter”) to be dated at or prior to the closing of the IPO by and between Subscriber and the Company, Subscriber agrees not to sell, transfer, pledge, hypothecate or otherwise dispose of all
or any part of the Shares unless, prior thereto (a) a registration statement on the appropriate form under the Securities Act and applicable state securities laws with respect to the Shares proposed to be transferred shall then be effective or
(b) the Company has received an opinion or advice from counsel reasonably satisfactory to the Company, that such registration is not required because such transaction is exempt from registration under the Securities Act and the
rules promulgated by the Securities and Exchange Commission thereunder and with all applicable state securities laws. 


  

	 	5.2.	 Lock-up. Subscriber acknowledges that the Shares will be subject
to lock-up provisions (the “Lock-up”) contained in the Insider Letter. 



 

	 	5.3.	 Restrictive Legends. All book-entries representing the Shares shall be subject to the following
restrictive legends: 


 “THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES
SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND NEITHER THE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
UNDER SUCH ACT OR SUCH LAWS OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT AND SUCH LAWS WHICH, IN THE OPINION OF COUNSEL, IS AVAILABLE.” 

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO LOCKUP PROVISIONS AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED
OR OTHERWISE DISPOSED DURING THE TERM OF THE LOCKUP PERIOD.” 
  

	 	5.4.	 Additional Shares or Substituted Securities. In the event of the declaration of a share dividend, the
declaration of a special dividend payable in a form other than Ordinary Shares, a spin-off, a share split, an adjustment in conversion ratio, a recapitalization or a similar transaction affecting the
Company’s outstanding Ordinary Shares without receipt of consideration, any new, substituted or additional securities or other property which are by reason of such transaction distributed with respect to any Shares subject to this
Section 5 or into which such Shares thereby become convertible shall immediately be subject to this Section 5 and Section 3. Appropriate adjustments to reflect the
distribution of such securities or property shall be made to the number or class of Ordinary Shares subject to this Section 5 and Section 3. 



 

	 	5.5.	 Registration Rights. Subscriber acknowledges that the Shares are being purchased pursuant to an
exemption from the registration requirements of the Securities Act and will become freely tradable only after certain conditions are met or they are registered pursuant to a registration rights agreement to be entered into with the Company at or
prior to the closing of the IPO (the “Registration Rights Agreement”). 















	6.	 Other Agreements. 



 

	 	6.1.	 Further Assurances. Subscriber agrees to execute such further instruments and to take such further
action as may reasonably be necessary to carry out the intent of this Agreement. 


  

	 	6.2.	 Notices. All notices, statements or other documents which are required or contemplated by this Agreement
shall be: (i) in writing and delivered personally or sent by first class registered or certified mail, overnight courier service or facsimile or electronic transmission to the address designated in writing, (ii) by facsimile to the number
most recently provided to such party or such other address or fax number as may be designated in writing by such party and (iii) by electronic mail, to the electronic mail address most recently provided to such party or such other electronic
mail address as may be designated in writing by such party. Any notice or other communication so transmitted shall be deemed to have been given on the day of delivery, if delivered personally, on the business day following receipt of written
confirmation, if sent by facsimile or electronic transmission, one (1) business day after delivery to an overnight courier service or five (5) days after mailing if sent by mail. 



 

	 	6.3.	 Entire Agreement. This Agreement, together with the Insider Letter and the Registration Rights
Agreement, each substantially in the form to be filed as an exhibit to the Company’s Registration Statement on Form S-1 for the IPO, embodies the entire agreement and understanding between the Subscriber
and the Company with respect to the subject matter hereof and supersedes all prior oral or written agreements and understandings relating to the subject matter hereof. No statement, representation, warranty, covenant or agreement of any kind not
expressly set forth in this Agreement shall affect, or be used to interpret, change or restrict, the express terms and provisions of this Agreement. 


  

	 	6.4.	 Modifications and Amendments. The terms and provisions of this Agreement may be modified or amended only
by written agreement executed by all parties hereto. 


  

	 	6.5.	 Waivers and Consents. The terms and provisions of this Agreement may be waived, or consent for the
departure therefrom granted, only by a written document executed by the party entitled to the benefits of such terms or provisions. No such waiver or consent shall be deemed to be or shall constitute a waiver or consent with respect to any other
terms or provisions of this Agreement, whether or not similar. Each such waiver or consent shall be effective only in the specific instance and for the purpose for which it was given, and shall not constitute a continuing waiver or consent.



  

	 	6.6.	 Assignment. The rights and obligations under this Agreement may not be assigned by either party hereto
without the prior written consent of the other party. 


  

	 	6.7.	 Benefit. All statements, representations, warranties, covenants and agreements in this Agreement shall
be binding on the parties hereto and shall inure to the benefit of the respective successors and permitted assigns of each party hereto. Nothing in this Agreement shall be construed to create any rights or obligations except among the parties
hereto, and no person or entity shall be regarded as a third-party beneficiary of this Agreement. 


  

	 	6.8.	 Governing Law. This Agreement and the rights and obligations of the parties hereunder shall be construed
in accordance with and governed by the laws of New York applicable to contracts wholly performed within the borders of such state, without giving effect to the conflict of law principles thereof. 



 

	 	6.9.	 Severability. In the event that any court of competent jurisdiction shall determine that any provision,
or any portion thereof, contained in this Agreement shall be unreasonable or unenforceable in any respect, then such provision shall be deemed limited to the extent that such court deems it reasonable and enforceable, and as so limited shall remain
in full force and effect. In the event that such court shall deem any such provision, or portion thereof, wholly unenforceable, the remaining provisions of this Agreement shall nevertheless remain in full force and effect. 



 

	 	6.10.	 No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising any right,
power or remedy under this Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or remedy under this Agreement
by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The
election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Agreement shall entitle the party receiving
such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice
or demand. 















	 	6.11.	 Survival of Representations and Warranties. All representations and warranties made by the parties
hereto in this Agreement or in any other agreement, certificate or instrument provided for or contemplated hereby, shall survive the execution and delivery hereof and any investigations made by or on behalf of the parties. 



 

	 	6.12.	 No Broker or Finder. Each of the parties hereto represents and warrants to the other that no broker,
finder or other financial consultant has acted on its behalf in connection with this Agreement or the transactions contemplated hereby in such a way as to create any liability on the other. Each of the parties hereto agrees to indemnify and hold the
other harmless from any claim or demand for commission or other compensation by any broker, finder, financial consultant or similar agent claiming to have been employed by or on behalf of such party and to bear the cost of legal expenses incurred in
defending against any such claim. 


  

	 	6.13.	 Headings and Captions. The headings and captions of the various sections of this Agreement are for
convenience of reference only and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof. 


  

	 	6.14.	 Counterparts; Electronic Signature. This Agreement may be executed in one or more counterparts, all of
which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same
counterpart. In the event that any signature is delivered by facsimile transmission or any other form of electronic delivery, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is
executed) with the same force and effect as if such signature page were an original thereof. The words “execution,” “signed,” “signature,” and words of like import in this Agreement or in any other certificate,
agreement or document related to this Agreement shall include images of manually executed signatures transmitted by facsimile or other electronic format (including, without limitation, “pdf”, “tif” or “jpg”) and other
electronic signatures (including, without limitation, DocuSign and AdobeSign). The use of electronic signatures and electronic records (including, without limitation, any contract or other record created, generated, sent, communicated, received, or
stored by electronic means) shall be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based record-keeping system to the fullest extent permitted by applicable law, including the Federal
Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act or the
Uniform Commercial Code. 


  

	 	6.15.	 Construction. The parties hereto have participated jointly in the negotiation and drafting of this
Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any party hereto because
of the authorship of any provision of this Agreement. The words “include,” “includes,” and “including” will be deemed to be followed by “without limitation.” Pronouns in masculine,
feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this Agreement,”
“herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The
parties hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect, the fact that
there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party
hereto is in breach of the first representation, warranty, or covenant. 















	 	6.16.	 Mutual Drafting. This Agreement is the joint product of the Subscriber and the Company and each
provision hereof has been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party hereto. 



 

	7.	 Voting and Redemption of Shares. Subscriber agrees to vote the Shares in favor of an initial business
combination that the Company negotiates and submits for approval to the Company’s shareholders and shall not seek redemption with respect to such Shares in connection with an initial business combination or any amendment to the Company’s
Memorandum and Articles of Association, as amended, prior to an initial business combination. Additionally, the Subscriber agrees not to redeem any Shares in connection with a redemption or tender offer presented to the Company’s shareholders
in connection with an initial business combination negotiated by the Company. 


  

	8.	 Indemnification. Each party shall indemnify the other against any loss, cost or damages (including
reasonable attorney’s fees and expenses) incurred as a result of such party’s breach of any representation, warranty, covenant or agreement in this Agreement.
