Exhibit 2.1

DESCRIPTION OF SECURITIES

A summary of the material provisions governing our securities registered pursuant to Section 12(b) of the Exchange Act of 1934, as amended (the “Exchange Act”) is provided below. This summary is not complete and should be read together with our amended and restated memorandum and articles of association (the “Articles”), a copy of which is filed with the U.S. Securities Exchange and Commission (the “SEC”). References herein to “we,” “us,” “our,” “Wellchange” and the “Company” are to WELLCHANGE HOLDINGS COMPANY LIMITED.

We are a Cayman Islands exempted company, and our affairs are governed by our Articles and the Companies Act (Revised) of the Cayman Islands, which we refer to as the Companies Act below (each as amended or modified from time to time). We had the following series of securities registered pursuant to Section 12(b) of the Exchange Act:

As provided in the Articles, our authorized share capital is US$50,000 divided into 1,000,000,000 ordinary shares of par value USD0.00005 each (“Ordinary Shares”).

Ordinary Shares

General

All of our outstanding Ordinary Shares are fully paid and non-assessable. Our shareholders who are non-residents of the Cayman Islands may freely hold and vote their Ordinary Shares. We may not issue shares to bearer.

Dividends

Subject to the Companies Act and our Memorandum and Articles of Association, the directors may from time to time declare dividends (including interim dividends) and other distributions on shares in issue and authorize payment of the same out of the funds of the Company lawfully available therefor. The Company by ordinary resolution may declare dividends, but no dividend shall exceed the amount recommended by the directors.

Subject to any rights and restrictions for the time being attached to any shares of the Company, all dividends shall be declared and paid according to the amounts paid up on the Shares, but if and for so long as nothing is paid up on any of the shares dividends may be declared and paid according to the par value of the shares. No amount paid on a share in advance of calls shall, while carrying interest, be treated as paid on the share.

The directors may determine that a dividend shall be paid wholly or partly by the distribution of specific assets (which may consist of the shares or securities of any other company) and may settle all questions concerning such distribution. Without limiting the generality of the foregoing, the directors may fix the value of such specific assets, may determine that cash payment shall be made to some shareholders in lieu of specific assets and may vest any such specific assets in trustees on such terms as the directors think fit.

Voting Rights

Subject to any special rights, restrictions or privileges as to voting for the time being attached to any class or classes of shares at any general meeting: (a) on a show of hands every shareholder present in person or by proxy (or, if a corporation or other non-natural person, by its duly authorized representative or proxy) shall, at a general meeting of the Company, each have one vote; and (b) on a poll every shareholder present in person or by proxy (or, if a corporation or other non-natural person, by its duly authorized representative or proxy) shall have one vote for each Ordinary Share of which he is the holder. Each shareholder, other than a recognized clearing house (or its nominee(s)) or depositary (or its nominee(s)), may only appoint one proxy on a show of hand and on a poll, each such proxy is under no obligation to cast all his votes in the same way. On a poll, a member entitled to more than one vote need not use all his votes or cast all the votes he does use in the same way.

Transfer of Ordinary Shares

Subject to the Companies Act and our Memorandum and Articles of Association, all transfers of shares shall be effected by an instrument of transfer in the usual or common form or in a form prescribed by the Nasdaq or in such other form as our board of directors may approve and may be under hand or, if the transferor or transferee is a clearing house (or its nominee(s)) or a central depository house (or its nominee(s)), under hand or by machine imprinted signature, or by such other manner of execution as our board of directors may approve from time to time.

The instrument of transfer of any share shall be in writing and in any usual or common form or such other form as the directors may, in their absolute discretion, approve and be executed by or on behalf of the transferor and if in respect of a nil or partly paid up share, or if so required by the directors, shall also be executed on behalf of the transferee and shall be accompanied by the certificate (if any) of the shares to which it relates and such other evidence as the directors may reasonably require to show the right of the transferor to make the transfer. The transferor shall be deemed to remain a shareholder until the name of the transferee is entered in our register of members in respect of the relevant shares.

Our board of directors may, in their absolute discretion, decline to register a transfer of any share which is not fully paid up or on which our Company has a lien. It may also decline to register a transfer of any share to more than four joint holders.

Our board of directors may decline to recognize any instrument of transfer unless:

The registration of transfers of shares or of any class of shares may, after compliance with any notice requirement of Nasdaq, be suspended at such times and for such periods (not exceeding in the whole thirty days in any calendar year) as our board of directors may determine.

Fully paid shares shall be free from any restriction on transfer (except when permitted by Nasdaq) and shall also be free from all liens.

Procedures on liquidation

Subject to any special rights, privileges or restrictions as to the distribution of available surplus assets on liquidation for the time being attached to any class or classes of shares:

If our Company is wound up (whether the liquidation is voluntary or compelled by the court), the liquidator may, with the sanction of a special resolution and any other sanction required by the Companies Act, divide among the members in specie or kind the whole or any part of the assets of our Company, whether the assets consist of property of one kind or different kinds, and the liquidator may, for such purpose, set such value as he deems fair upon any one or more class or classes of property to be so divided and may determine how such division shall be carried out as between the members or different classes of members and the members within each class. The liquidator may, with the like sanction, vest any part of the assets in trustees upon such trusts for the benefit of members as the liquidator thinks fit, but so that no member shall be compelled to accept any shares or other property upon which there is a liability.

Calls on Ordinary Shares and Forfeiture of Ordinary Shares

Subject to our Memorandum and Articles of Association and to the terms of allotment, our board of directors may, from time to time, make such calls as it thinks fit upon the members in respect of any monies unpaid on the shares held by them respectively, and each shareholder shall (subject to receiving at least fourteen calendar days’ notice specifying the time or times of payment) pay to the Company at the time or times so specified the amount called on such shares. A call shall be deemed to have been made at the time when the resolution of the directors authorizing such call was passed. A call may be made payable either in one sum or by instalments. If the sum payable in respect of any call or instalment is not paid on or before the day appointed for payment thereof, the person or persons from whom the sum is due shall pay interest on the same at such rate of 8% per annum from the day appointed for payment to the time of actual payment, but our board of directors may waive payment of such interest wholly or in part. Our board of directors may, if it thinks fit, receive from any member willing to advance the same, either in money or money’s worth, all or any part of the money uncalled and unpaid or instalments payable upon any shares held by him, and in respect of all or any of the monies so advanced our Company may pay interest at such rate (if any) not exceeding without the sanction of an ordinary resolution 8% per annum as our board of directors may decide.

If a member fails to pay any call or instalment of a call on the day appointed for payment, our board of directors may, at any time thereafter during such time as any part of such call or instalment remains unpaid, serve a notice on the member requiring payment of so much of the call or instalment as is unpaid, together with any interest which may have accrued. The notice shall name a further day (not earlier than the expiration of 14 calendar days from the date of the notice) on or before which the payment required by the notice is to be made, and shall also name the place where payment is to be made. The notice shall also state that, in the event of non-payment at or before the appointed time, the shares in respect of which the call was made will be liable to be forfeited.

If the requirements of any such notice are not complied with, any share in respect of which the notice has been given may at any time thereafter, before the payment required by the notice has been made, be forfeited by a resolution of our board of directors to that effect.

A person whose shares have been forfeited shall cease to be a member in respect of the forfeited shares but shall, notwithstanding, remain liable to pay to the Company all moneys which at the date of forfeiture were payable by him to the Company in respect of the Shares forfeited, but his liability shall cease if and when the Company receives payment in full of the amount unpaid on the Shares forfeited.

Redemption of Ordinary Shares

Subject to the Companies Act and our Memorandum and Articles of Association, the Company may:

Variations of Rights of Shares

Subject to the Companies Act and without prejudice to our Articles of Association, if at any time the share capital of our Company is divided into different classes of shares, all or any of the special rights attached to any class of shares may (unless otherwise provided for by the terms of issue of the shares of that class) be varied with the consent in writing of all of the holders of the issued shares of that class or the sanction of a special resolution passed at a separate general meeting of the holders of the shares of that class. The provisions of the Articles relating to general meetings shall mutatis mutandis apply to every such separate general meeting, but so that the necessary quorum (whether at a separate general meeting or at its adjourned meeting) shall be not less than a person or persons together holding (or, in the case of a member being a corporation, by our duly authorized representative) or representing by proxy not less than one-third in nominal value of the issued shares of that class. Every holder of shares of the class shall be entitled on a poll to one vote for every such share held by him, and any holder of shares of the class present in person or by proxy may demand a poll.

Any special rights conferred upon the holders of any shares or class of shares shall not, unless otherwise expressly provided in the rights attaching to the terms of issue of such shares, be deemed to be varied by the creation or issue of further shares ranking pari passu therewith.

General Meetings of Shareholders

Our Company may (but shall not be obliged to, unless as required by applicable law or the rules of the Nasdaq Capital Market) in each calendar year hold a general meeting as its annual general meeting and shall specify the meeting as such in the notices calling it. The annual general meeting shall be held at such time and place as may be determined by the directors.

The chairman of the board or a majority of the directors may call general meetings, and they shall on a shareholders’ requisition forthwith proceed to convene an extraordinary general meeting of the Company. Extraordinary general meetings may be convened on the requisition of two or more members holding at the date of deposit of the requisition shares which carry in aggregate not less than one-third (1/3) of all votes attaching to all issued and outstanding shares of the Company that as at the date of the deposit carry the right to vote at general meetings of the Company. The requisition must state the objects of the meeting and must be signed by the requisitionists and deposited at the registered office of the Company, and may consist of several documents in like form each signed by one or more requisitionists. If there are no directors as at the date of the deposit of the shareholders’ requisition, or if the directors do not within twenty-one calendar days from the date of the deposit of the requisition duly proceed to convene a general meeting to be held within a further twenty-one calendar days, the requisitionists, or any of them representing more than one-half of the total voting rights of all of them, may themselves convene a general meeting, but any meeting so convened shall not be held after the expiration of three calendar months after the expiration of the said twenty-one calendar days.

Every general meeting of our Company shall be called by at least seven (7) calendar days’ notice in writing. The notice shall be exclusive of the day on which it is served or deemed to be served and of the day for which it is given, and must specify the place, the day and the hour of the meeting and the general nature of that business.

Although a meeting of our Company may be called by shorter notice than as specified above, such meeting may be deemed to have been duly called if it is so agreed:

No business other than the appointment of a chairman of a meeting shall be transacted at any general meeting unless a quorum is present when the meeting proceeds to business.

The quorum for a general meeting shall be one or more shareholders who together hold shares which carry in aggregate not less than one-third (1/3) of all votes attaching to all issued and outstanding shares that carry the right to vote at such general meeting, present in person or by proxy or, if a corporation or other non-natural person, by its duly authorized representative.

Inspection of Books and Records

Holders of our ordinary shares have no general right under Cayman Islands law to inspect or obtain copies of our list of shareholders or our corporate records (other than copies of our amended and restated memorandum and articles of association, our register of mortgage and charges and any special resolutions passed by our shareholders). Under Cayman Islands law, the names of our current directors can be obtained from a search conducted at the Registrar of Companies.

Changes in Capital

Subject to the Companies Act, our shareholders may, by ordinary resolution:

Subject to the Companies Act and to any rights for the time being conferred on the shareholders holding a particular class of shares, our shareholders may, by special resolution, reduce our share capital or any capital redemption reserve in any way authorized by law.

Certain Cayman Islands Company Considerations

Exempted Company

We are an exempted company with limited liability under the Companies Act. The Companies Act distinguishes between ordinary resident companies and exempted companies. Any company that is incorporated in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except for the exemptions and privileges listed below:

“Limited liability” means that the liability of each shareholder is limited to the amount unpaid by the shareholder on the shares of the company. (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil).

Differences in Corporate Law

The Companies Act is modeled after that of England and Wales but does not follow recent statutory enactments in England. In addition, the Companies Act differs from laws applicable to United States corporations and their shareholders. Set forth below is a summary of the significant differences between the provisions of the Companies Act applicable to us and the laws applicable to companies incorporated in the State of Delaware.

This discussion does not purport to be a complete statement of the rights of holders of our Ordinary Shares under applicable law in the Cayman Islands or the rights of holders of the common stock of a typical corporation under applicable Delaware law.

Mergers and Similar Arrangements

The Companies Act permits mergers and consolidations between Cayman Islands companies and between Cayman Islands companies and non-Cayman Islands companies. For these purposes, (a) “merger” means the merging of two or more constituent companies and the vesting of their undertaking, property and liabilities in one of such companies as the surviving company, and (b) a “consolidation” means the combination of two or more constituent companies into a consolidated company and the vesting of the undertaking, property and liabilities of such companies to the consolidated company. In order to effect such a merger or consolidation, the directors of each constituent company must approve a written plan of merger or consolidation, which must then be authorized by (a) a special resolution of the shareholders of each constituent company, and (b) such other authorization, if any, as may be specified in such constituent company’s articles of association. The plan must be filed with the Registrar of Companies of the Cayman Islands together with a declaration as to the solvency of the consolidated or surviving company, a statement setting out the assets and liabilities of each constituent company and an undertaking that a copy of the certificate of merger or consolidation will be given to the members and creditors of each constituent company and that notification of the merger or consolidation will be published in the Cayman Islands Gazette. Court approval is not required for a merger or consolidation which is effected in compliance with these statutory procedures.

A merger between a Cayman Islands parent company and its Cayman Islands subsidiary or subsidiaries does not require authorization by a resolution of shareholders. For this purpose a subsidiary is a company of which at least ninety percent (90%) of the issued shares entitled to vote are owned by the parent company.

The consent of each holder of a fixed or floating security interest over a constituent company is required unless this requirement is waived by a court in the Cayman Islands.

Save in certain circumstances, a dissenting shareholder of a Cayman Islands constituent company is entitled to payment of the fair value of his shares upon dissenting to a merger or consolidation. The exercise of appraisal rights will preclude the exercise of any other rights save for the right to seek relief on the grounds that the merger or consolidation is void or unlawful.

Separate from the statutory provisions relating to mergers and consolidations, the Companies Act also contains statutory provisions that facilitate the reconstruction and amalgamation of companies by way of schemes of arrangement, provided that the arrangement is approved by (a) seventy-five percent (75%) in value of the shareholders or class of shareholders, as the case may be, or (b) a majority in number of the creditors or each class of creditors, as the case may be, with whom the arrangement is to be made, that are, in each case present and voting either in person or by proxy at a meeting, or meetings, convened for that purpose. The convening of the meetings and subsequently the arrangement must be sanctioned by the Grand Court of the Cayman Islands. While a dissenting shareholder has the right to express to the court the view that the transaction ought not to be approved, the court can be expected to approve the arrangement if it determines that:

The Companies Act also contains a statutory power of compulsory acquisition which may facilitate the “squeeze out” of dissentient minority shareholder upon a tender offer. When a tender offer is made and accepted by holders of ninety percent (90%) of the shares affected within four months, the offeror may, within a two-month period commencing on the expiration of such four-month period, require the holders of the remaining shares to transfer such shares to the offeror on the terms of the offer. An objection can be made to the Grand Court of the Cayman Islands.

If an arrangement and reconstruction is thus approved, the dissenting shareholder would have no rights comparable to appraisal rights, which would otherwise ordinarily be available to dissenting shareholders of Delaware corporations, providing rights to receive payment in cash for the judicially determined value of the shares.

Shareholders’ Suits

In principle, we will normally be the proper plaintiff and as a general rule a derivative action may not be brought by a minority shareholder. However, based on English authorities, which would in all likelihood be of persuasive authority in the Cayman Islands, the Cayman Islands court can be expected to follow and apply the common law principles (namely the rule in Foss v. Harbottle and the exceptions thereto) so that a non-controlling shareholder may be permitted to commence a class action against or derivative actions in the name of the company to challenge actions where:

Indemnification of Directors and Executive Officers and Limitation of Liability

Cayman Islands law does not limit the extent to which a company’s memorandum and articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against civil fraud or the consequences of committing a crime. Our Memorandum and Articles of Association provide that, every director (including any alternate director), secretary, assistant secretary, or other officer for the time being and from time to time of the Company (but not including the Company’s auditors) and the personal representatives of the same (each an “Indemnified Person”) shall be indemnified and secured harmless against all actions, proceedings, costs, charges, expenses, losses, damages or liabilities incurred or sustained by such Indemnified Person, other than by reason of such Indemnified Person’s own dishonesty, willful default or fraud, in or about the conduct of the Company’s business or affairs (including as a result of any mistake of judgment) or in the execution or discharge of his duties, powers, authorities or discretions, including without prejudice to the generality of the foregoing, any costs, expenses, losses or liabilities incurred by such Indemnified Person in defending (whether successfully or otherwise) any civil proceedings concerning the Company or its affairs in any court whether in the Cayman Islands or elsewhere.

This standard of conduct is generally the same as permitted under the Delaware General Corporation Act for a Delaware corporation. In addition, we intend to enter into indemnification agreements with our directors and senior executive officers that will provide such persons with additional indemnification beyond that provided in our Memorandum and Articles of Association. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers or persons controlling us under the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Directors’ Fiduciary Duties

Under Delaware corporate law, a director of a Delaware corporation has a fiduciary duty to the corporation and its shareholders. This duty has two components: the duty of care and the duty of loyalty. The duty of care requires that a director act in good faith, with the care that an ordinarily prudent person would exercise under similar circumstances. Under this duty, a director must inform himself of, and disclose to shareholders, all material information reasonably available regarding a significant transaction. The duty of loyalty requires that a director act in a manner he or she reasonably believes to be in the best interests of the corporation. He or she must not use his or her corporate position for personal gain or advantage. This duty prohibits self-dealing by a director and mandates that the best interest of the corporation and its shareholders take precedence over any interest possessed by a director, officer or controlling shareholder and not shared by the shareholders generally. In general, actions of a director are presumed to have been made on an informed basis, in good faith and in the honest belief that the action taken was in the best interests of the corporation. However, this presumption may be rebutted by evidence of a breach of one of the fiduciary duties. Should such evidence be presented concerning a transaction by a director, a director must prove the procedural fairness of the transaction, and that the transaction was of fair value to the corporation.

As a matter of Cayman Islands law, a director of a Cayman Islands company is in the position of a fiduciary with respect to the company and therefore it is considered that he owes the following duties to the company — a duty to act bona fide in the best interests of the company, a duty not to make a profit based on his or her position as director (unless the company permits him to do so) and a duty not to put himself in a position where the interests of the company conflict with his or her personal interest or his or her duty to a third party. A director of a Cayman Islands company owes to the company a duty to act with skill and care. It was previously considered that a director need not exhibit in the performance of his or her duties a greater degree of skill than may reasonably be expected from a person of his or her knowledge and experience. However, English and Commonwealth courts have moved towards an objective standard with regard to the required skill and care and these authorities are likely to be followed in the Cayman Islands.

Shareholder Action by Written Consent

Under the Delaware General Corporation Act, a corporation may eliminate the right of shareholders to act by written consent by amendment to its certificate of incorporation. Our Articles of Association provide that shareholders may approve corporate matters by way of a unanimous written resolution signed by or on behalf of each shareholder who would have been entitled to vote on such matter at a general meeting without a meeting being held.

Shareholder Proposals

Under the Delaware General Corporation Act, a shareholder has the right to put any proposal before the annual meeting of shareholders, provided it complies with the notice provisions in the governing documents. A special meeting may be called by the board of directors or any other person authorized to do so in the governing documents, but shareholders may be precluded from calling special meetings.

The Companies Act does not provide shareholders with rights to requisition a general meeting nor any right to put any proposal before a general meeting. However, these rights may be provided in a company’s articles of association. Our Articles of Association allow any two or more members holding at the date of deposit of the requisition shares which carry in aggregate not less than one-third (1/3) of all votes attaching to all issued and outstanding shares of the Company that as at the date of the deposit carry the right to vote at general meetings of the Company to requisition a general meeting. Other than this right to requisition a shareholders’ meeting, our Articles of Association do not provide our shareholders with any other right to put proposals before annual general meetings or extraordinary general meetings. As an exempted Cayman Islands company, we are not obliged by law to call shareholders’ annual general meetings.

Cumulative Voting

Under the Delaware General Corporation Act, cumulative voting for elections of directors is not permitted unless the corporation’s certificate of incorporation specifically provides for it. Cumulative voting potentially facilitates the representation of minority shareholders on a board of directors since it permits the minority shareholder to cast all the votes to which the shareholder is entitled on a single director, which increases the shareholder’s voting power with respect to electing such director. As permitted under Cayman Islands law, our Articles of Association do not provide for cumulative voting. As a result, our shareholders are not afforded any less protections or rights on this issue than shareholders of a Delaware corporation.

Removal of Directors

Under the Delaware General Corporation Law, a director of a corporation with a classified board may be removed only for cause with the approval of a majority of the issued and outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. Under our Articles of Association, directors may be removed by an ordinary resolution of our shareholders.

Transactions with Interested Shareholders

The Delaware General Corporation Act contains a business combination statute applicable to Delaware corporations whereby, unless the corporation has specifically elected not to be governed by such statute by amendment to its certificate of incorporation, it is prohibited from engaging in certain business combinations with an “interested shareholder” for three years following the date that such person becomes an interested shareholder. An interested shareholder generally is a person or a group who or which owns or owned 15% or more of the target’s outstanding voting stock within the past three years. This has the effect of limiting the ability of a potential acquirer to make a two-tiered bid for the target in which all shareholders would not be treated equally. The statute does not apply if, among other things, prior to the date on which such shareholder becomes an interested shareholder, the board of directors approves either the business combination or the transaction which resulted in the person becoming an interested shareholder. This encourages any potential acquirer of a Delaware corporation to negotiate the terms of any acquisition transaction with the target’s board of directors.

Cayman Islands law has no comparable statute. As a result, we cannot avail ourselves of the types of protections afforded by the Delaware business combination statute. However, although Cayman Islands law does not regulate transactions between a company and its significant shareholders, it does provide that such transactions must be entered into bona fide in the best interests of the company and for a proper corporate purpose and not with the effect of constituting a fraud on the minority shareholders.

Dissolution; Winding Up

Under the Delaware General Corporation Act, unless the board of directors approves the proposal to dissolve, dissolution must be approved by shareholders holding 100% of the total voting power of the corporation. Only if the dissolution is initiated by the board of directors may it be approved by a simple majority of the corporation’s outstanding shares. Delaware law allows a Delaware corporation to include in its certificate of incorporation a supermajority voting requirement in connection with dissolutions initiated by the board.

Under Cayman Islands law, a company may be wound up by either an order of the courts of the Cayman Islands or by a special resolution of its members or, if the company is unable to pay its debts as they fall due, by an ordinary resolution of its members. The court has authority to order winding up in a number of specified circumstances including where it is, in the opinion of the court, just and equitable to do so. Under the Companies Act and our Articles of Association, our company may be dissolved, liquidated or wound up by a special resolution of our shareholders.

Variation of Rights of Shares

Under the Delaware General Corporation Act, a corporation may vary the rights of a class of shares with the approval of a majority of the outstanding shares of such class, unless the certificate of incorporation provides otherwise. Under our Articles of Association, if our share capital is divided into more than one class of shares, we may vary the rights attached to any class with the consent in writing of all of the holders of the issued shares of that class or with the sanction of a special resolution passed at a separate meeting of the holders of the shares of that class.

Amendment of Governing Documents

Under the Delaware General Corporation Act, a corporation’s governing documents may be amended with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. Subject to Cayman Islands law, our Memorandum and Articles of Association may only be amended by a special resolution of our shareholders.

Rights of Non-Resident or Foreign Shareholders

There are no limitations imposed by our Memorandum and Articles of Association on the rights of non-resident or foreign shareholders to hold or exercise voting rights on our shares. In addition, there are no provisions in our Memorandum and Articles of Association governing the ownership threshold above which shareholder ownership must be disclosed.
