Exhibit 4.2

Description of Securities

Registered under Section 12 of the Securities Exchange Act of 1934

As of March 31, 2026, AIOS Tech Inc. (“AIOS,” the “Company,” “we,” “us,” and “our”) had one class of securities registered pursuant to Section 12 of the Securities Exchange Act of 1934, as amended, as follows:

Common shares

The Company is authorized to issue a maximum of 10,000,000,000 common shares divided into:

(a) 9,600,000,000 Class A common shares of a nominal or par value of US$0.0001 each (Class A common shares); and

(b) 400,000,000 Class B common shares of a nominal or par value of US$0.0001 each (Class B common shares, together with Class A common shares, the common shares or shares).

Dividend distributions

The holders of our common shares are entitled to such dividends as may be declared by our board of directors subject to the BVI Business Companies Act.

Voting rights

Any action required or permitted to be taken by the shareholders must be effected at a duly called meeting of the shareholders entitled to vote on such action and may be effected by a resolution in writing. At each shareholder’s meeting, each shareholder who is present in person or by proxy (or, in the case of a shareholder being a corporation, by its duly authorized representative) will be entitled to one vote for each Class A common share which such shareholder holds and be entitled to 100 votes for each Class B common share which such shareholder holds on all matters subject to vote at each shareholders’ meeting of the Company.

Conversion

Each Class B common share is convertible into one (1) Class A common share at any time by the holder thereof. The right to convert shall be exercisable by the holder of the Class B common share delivering a written notice to the Company that such holder elects to convert a specified number of Class B common shares into Class A common shares.

The number of Class B common shares held by a holder thereof will be automatically and immediately converted into an equal and corresponding number of Class A common shares upon any direct or indirect sale, transfer, assignment or disposition of such number of Class B common shares by the holder thereof or an Affiliate or such holder or the direct or indirect transfer or assignment of the voting power attached to such number of Class B common shares through voting proxy or otherwise to any person or entity that is not an affiliate of such holder. For the avoidance of doubt, the creation of any pledge, charge, encumbrance or other third party right of whatever description on any of Class B common shares to secure contractual or legal obligations shall not be deemed as a sale, transfer, assignment or disposition unless and until any such pledge, charge, encumbrance or other third-party right is enforced and results in the third party holding directly or indirectly beneficial ownership or voting power through voting proxy or otherwise to the related Class B common shares, in which case all the related Class B common shares shall be automatically converted into the same number of Class A common shares.

Election of directors

Delaware law permits cumulative voting for the election of directors only if expressly authorized in the certificate of incorporation. The laws of the British Virgin Islands, however, do not specifically prohibit or restrict the creation of cumulative voting rights for the election of our directors. Cumulative voting is not a concept that is accepted as a common practice in the British Virgin Islands, and we have made no provisions in our amended and restated memorandum and articles of association to allow cumulative voting for elections of directors. 

Meetings

We must provide written notice of all meetings of shareholders, stating the time, place and, in the case of a special meeting of shareholders, the purpose or purposes thereof, at least 7 days before the date of the proposed meeting to those persons whose names appear as shareholders in the register of members on the date of the notice and are entitled to vote at the meeting. Our board of directors shall call a special meeting upon the written request of shareholders holding at least 30% of our outstanding voting shares. In addition, our board of directors may call a special meeting of shareholders on its own motion. A meeting of shareholders held in contravention of the requirement to give notice is valid if shareholders holding at least 90 percent of the total voting rights on all the matters to be considered at the meeting have waived notice of the meeting and, for this purpose, the presence of a shareholder at the meeting shall constitute waiver in relation to all the shares which that shareholder holds.

The management of us is entrusted to our board of directors, who will make corporate decisions by board resolution. Our directors are free to meet at such times and in such manner and places within or outside the BVI as the directors determine to be necessary or desirable. A 3 days’ notice of a meeting of directors must be given. At any meeting of directors, a quorum will be present if half of the total number of directors is present, unless there are only 2 directors in which case the quorum is 2. If a quorum is not present, the meeting will be dissolved. If a quorum is present, votes of half of present directors are required to pass a resolution of directors.

A meeting of shareholders is duly constituted if, at the commencement of the meeting, there are present in person or by proxy not less than one-third (1/3) of the votes of the shares entitled to vote on resolutions of shareholders to be considered at the meeting. A quorum may comprise a single shareholder or proxy and then such person may pass a resolution of shareholders and a certificate signed by such person accompanied where such person be a proxy by a copy of the proxy instrument shall constitute a valid resolution of shareholders. If within two hours from the time appointed for the meeting a quorum is not present, the meeting, if convened upon the requisition of shareholders, shall be dissolved; in any other case it shall stand adjourned to the next business day in the jurisdiction in which the meeting was to have been held at the same time and place or to such other time and place as the directors may determine, and if at the adjourned meeting there are present within one hour from the time appointed for the meeting in person or by proxy not less than one third (1/3) of the votes of the shares or each class or series of shares entitled to vote on the matters to be considered by the meeting, those present shall constitute a quorum but otherwise the meeting shall be dissolved. No business may be transacted at any general meeting unless a quorum is present at the commencement of business. If present, the chairman of our board of directors shall be the chairman presiding at any meeting of the shareholders.

A corporation that is a shareholder shall be deemed for the purpose of our amended and restated memorandum and articles of association to be present in person if represented by its duly authorized representative. This duly authorized representative shall be entitled to exercise the same powers on behalf of the corporation which he represents as that corporation could exercise if it were our individual shareholder. 

Protection of minority shareholders

We would normally expect British Virgin Islands courts to follow English case law precedents, which permit a minority shareholder to commence a representative action, or derivative actions in our name, to challenge (1) an act which is ultra vires or illegal, (2) an act which constitutes a fraud against the minority by parties in control of us, (3) the act complained of constitutes an infringement of individual rights of shareholders, such as the right to vote and pre-emptive rights and (4) an irregularity in the passing of a resolution which requires a special or extraordinary majority of the shareholders. 

Pre-emptive rights

There are no pre-emptive rights applicable to the issue by us of new common shares under either British Virgin Islands law or our amended and restated memorandum and articles of association. 

Transfer of common shares

Subject to the restrictions in our amended and restated memorandum and articles of association and applicable securities laws, any of our shareholders may transfer all or any of his or her common shares by written instrument of transfer signed by the transferor and containing the name and address of the transferee. Our board of directors may resolve by resolution to refuse or delay the registration of the transfer of any common share. If our board of directors resolves to refuse or delay any transfer, it shall specify the reasons for such refusal in the resolution. Our directors may not resolve or refuse or delay the transfer of a common share unless the shareholder has failed to pay an amount due in respect of the share.  

Liquidation

If we are wound up and the assets available for distribution among our shareholders are more than sufficient to repay all amounts paid to us on account of the issue of shares immediately prior to the winding up, the excess shall be distributable pari passu among those shareholders in proportion to the amount paid up immediately prior to the winding up on the shares held by them, respectively. If we are wound up and the assets available for distribution among the shareholders as such are insufficient to repay the whole of the amounts paid to us on account of the issue of shares, those assets shall be distributed so that, to the greatest extent possible, the losses shall be borne by the shareholders in proportion to the amounts paid up immediately prior to the winding up on the shares held by them, respectively. If we are wound up, the liquidator appointed by us may, in accordance with the BVI Business Companies Act, divide among our shareholders in specie or kind the whole or any part of our assets (whether they shall consist of property of the same kind or not) and may, for such purpose, set such value as the liquidator deems fair upon any property to be divided and may determine how such division shall be carried out as between the shareholders or different classes of shareholders. 

Calls on common shares and forfeiture of common shares

Our board of directors may from time to time make calls upon shareholders for any amounts unpaid on their common shares in a notice served to such shareholders at least 14 days prior to the specified time of payment. The common shares that have been called upon and remain unpaid are subject to forfeiture. 

Redemption of common shares

The Company may purchase, redeem or otherwise acquire and hold its own shares in such manner and upon such other terms as the directors may agree with the relevant shareholder(s) save that the Company may not purchase, redeem or otherwise acquire its own shares without the consent of shareholders whose shares are to be purchased, redeemed or otherwise acquired unless the Company is permitted by the BVI Business Companies Act or any other provision in the amended and restated memorandum or articles to purchase, redeem or otherwise acquire the shares without their consent.

The Company may only offer to purchase, redeem or otherwise acquire shares if the resolution of directors authorising the purchase, redemption or other acquisition contains a statement that the directors are satisfied, on reasonable grounds, that immediately after the acquisition the value of the Company’s assets will exceed its liabilities and the Company will be able to pay its debts as they fall due.

Modifications of rights

If at any time our shares are divided into different classes, the rights attached to any class may only be varied, whether or not the Company is in liquidation, with the consent in writing of or by a resolution passed at a meeting by the holders of not less than 50 percent of the issued shares in that class. 

Changes in the number of shares we are authorized to issue and those in issue

We may from time to time by resolution of our board of directors:

Inspection of books and records

Under British Virgin Islands Law, holders of our common shares are entitled, upon giving written notice to us, to inspect (i) our amended and restated memorandum and articles of association, (ii) the register of members, (iii) the register of directors and (iv) minutes of meetings and resolutions of members, and to make copies and take extracts from the documents and records. However, our directors can refuse access if they are satisfied that to allow such access would be contrary to our interests.  

Rights of non-resident or foreign shareholders

There are no limitations imposed by our amended and restated 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 amended and restated memorandum and articles of association governing the ownership threshold above which shareholder ownership must be disclosed.

Issuance of additional common shares

Our amended and restated memorandum and articles of association authorizes our board of directors to issue additional common shares from authorized but unissued shares, to the extent available, from time to time as our board of directors shall determine.
