Model Answer & Review

1 Introduction and Scope

You have asked for our preliminary assessment of the proposed initial public offering of Sino Tech Holdings Ltd (the "Company"), the Cayman incorporated holding vehicle for the Tech Solutions Limited operating group ("TSL" or the "Group"), on the Main Board of The Stock Exchange of Hong Kong Limited (the "Exchange"). At the outset it is important to be clear about our role. We act for the underwriting syndicate, not for the Company. Our function is to protect your interests by identifying the exposures that could affect the marketability of the offer, expose you to liability under the prospectus, or trigger your termination and force majeure rights, and to work alongside, but not in substitution for, the sponsor, whose own due diligence obligations under Practice Note 21 to the Listing Rules drive much of the process.

This memorandum addresses the four matters you have raised, namely the founder's matrimonial proceedings, the loss of the Zhonghai contract, the Nexcode patent claim, and the contractual (VIE) structure, and it sets out our recommendations on due diligence, disclosure, risk factors, documentation, timing, and the professional issues that arise. Three preliminary observations frame everything that follows. First, the listing applicant is the Cayman company, while the substance of the business and most of the risk sit in the PRC operating entities; the two must not be conflated. Second, several of these issues are interconnected, and the value of our analysis lies in those connections rather than in treating each in isolation. Third, several of these matters cannot be resolved on any realistic timetable and must instead be managed, ring fenced and disclosed.

2 The Founder's Matrimonial Proceedings

Mr. Ko holds approximately 60% of the Company and is the individual on whom the Exchange's assessment of management stability and control will turn. His matrimonial proceedings therefore go to the heart of the eligibility analysis, because the Exchange will be reluctant to clear the listing while there is genuine uncertainty over who controls the controlling stake.

We need to establish, across both the Hong Kong and the PRC dimensions of the proceedings, whether the shares are matrimonial property capable of division, whether any interim, freezing or injunctive orders bind the shares, and whether any charge, undertaking or lis pendens already affects them. We should obtain a family law opinion in each relevant jurisdiction on whether and how a spouse could reach the shares. Because the outcome is outside our control and outside any listing timetable, the practical objective is not to wait for the divorce to conclude but to insulate the offering from it. That is likely to require some combination of an undertaking from Mr. Ko, an escrow or a holding vehicle or trust arrangement that fixes the position of the shares for the relevant period, together with candid disclosure. In the prospectus, disclosure should address the consequences, namely the risk to control continuity, any orders or charges, and the ring fencing measures adopted, rather than the intimate detail of the marriage. The interaction with the shareholders' agreement must also be checked: a charge or transfer restriction arising from the proceedings could breach the agreement or trigger the venture investors' rights, and that linkage needs to be run to ground early.

3 Loss of the Zhonghai Contract

The termination of the Zhonghai relationship, contributing roughly 15% of revenue (in the order of HK$75 million), is significant both commercially and for eligibility. Our first task is to establish the true grounds for termination, the notice and any cure rights, and whether the stated reason is the real one, because a termination for performance or dispute reasons carries very different disclosure and reputational consequences from an ordinary commercial non renewal.

The financial due diligence must then be layered: we need the track record figures presented both as reported and on a Zhonghai adjusted, conservative basis, so that we can confirm the profit requirement under Listing Rule 8.05 continues to be satisfied without this customer. Beyond Zhonghai itself, the loss raises a concentration question across the wider state owned enterprise client base, and we should review those contracts for change of control, policy driven or convenience termination clauses that could produce a cascade. Disclosure in the business and financial sections should be candid about the contribution Zhonghai made, the reason for its loss, the resulting concentration risk, and the Company's diversification response, ideally supported by pipeline evidence. The corresponding risk factor should be specific and, where possible, quantified.

4 The Nexcode Patent Claim

The patent infringement claim brought by Nexcode requires an independent technical and legal opinion addressing the strength of the infringement allegation, the validity of the asserted patent, how central the affected module is to the Group's product, and the cost and feasibility of engineering around it. That opinion will drive both the disclosure and the valuation, and until it is available the risk section cannot be finalised.

Disclosure of the claim must be handled carefully: it should be presented accurately as a contingent liability, but in terms that do not waive privilege or prejudice the Group's defence. In parallel, we recommend a full review of the Group's intellectual property chain of title, covering registrations by jurisdiction, employee and contractor invention assignment provisions, open source and third party licence compliance, and source code ownership, because a claim of this kind often exposes wider weaknesses in the IP position. On timing, the realistic outcomes are a negotiated resolution (a cross licence, royalty or acquisition of the relevant right), an engineered alternative, or defence of the claim, and the timetable should carry a contingency for each.

5 The Contractual (VIE) Arrangements

The Group operates through a variable interest entity structure to hold the PRC operating licences. The Exchange does not prohibit such structures but, under Guidance Letter HKEX-GL77-14, requires that they be adopted only to the extent necessary to address foreign ownership restrictions and that they be narrowly tailored. We must therefore first confirm that a genuine foreign investment restriction applies to the Group's licensed activities (for example a value added telecommunications or internet content licence) and that the structure is no broader than that restriction requires.

We then need to verify the enforceability and completeness of the full suite of control documents, namely the business co-operation, exclusive service, equity pledge, exclusive option and power of attorney agreements, and, importantly, the spousal consents of the nominee shareholders, an item frequently overlooked and directly relevant given Mr. Ko's circumstances. The actual operation of the structure, including the real economic and fund flows and their tax treatment, should be traced rather than assumed. A PRC law opinion is required both on the validity and enforceability of the arrangements and on the narrowly tailored analysis. Two regulatory clearances sit on the critical path: the filing with the CSRC under the Overseas Listing Trial Measures, and an assessment of whether the volume of user data handled by the Group's platform triggers a cybersecurity review under the applicable measures. Because these are the longest lead items in the deal, the PRC consultation and filing should begin immediately. Finally, the venture investors' proposed sell down must be tested against the 25% minimum public float requirement in Listing Rule 8.08, and the shareholders' agreement and any side letters checked to confirm that all special rights fall away on listing.

6 Prospectus Disclosure and Risk Factors

Taken together, the four issues call for coordinated disclosure rather than four isolated paragraphs. The business section should carry the Zhonghai loss and the diversification response; the directors and substantial shareholders sections should carry the control continuity and succession position arising from the matrimonial proceedings; a dedicated contractual arrangements section should carry the VIE necessity, enforceability and regulatory position; and the financial information and contingent liability disclosure should carry the Nexcode claim. The risk factors should be TSL specific and, where possible, quantified, describing the consequence of each risk without lapsing into boilerplate at one extreme or scaremongering at the other, and without smuggling mitigants into the risk wording. The principal risks fall into the familiar categories of business and operational (customer concentration and SOE dependence, obsolescence, cross border scalability), legal and regulatory (the Nexcode claim, IP title, VIE enforceability and the evolving CSRC and cybersecurity regime), control and management (the uncertainty over the 60% stake, key person dependence and the investor overhang), and market and industry risk.

7 Legal Documentation and Underwriting Protections

Our documentary review should extend well beyond the prospectus to the Zhonghai contract and termination notice, the shareholders' agreement and side letters, the complete VIE suite, Mr. Ko's service agreement and any share charges, and the IP chain of title. Each of these should be read for its interaction with the others. We will need to marshal the supporting comfort: PRC law opinions on the VIE, confirmation of the CSRC filing and the cybersecurity position, the independent patent opinion, the family law opinions, the auditors' comfort letters, and a working capital sufficiency confirmation. The underwriting agreement itself should be strengthened to reflect this risk profile, with expanded warranties, bespoke indemnities directed specifically at the three named exposures (the matrimonial position, the Zhonghai loss and the Nexcode claim), conditions precedent tied to the key opinions and regulatory clearances, robust material adverse change and force majeure provisions with clearly defined termination triggers, and appropriate disclosure undertakings and bring down comfort.

8 Timing

The Company should be advised, candidly, that a transaction of this profile is unlikely to complete in under twelve months and may well run to eighteen. The gating item is the matrimonial position, because the Exchange will not clear the control analysis while it remains genuinely open; the VIE regulatory workstream, comprising the CSRC filing and any cybersecurity review, is the longest lead item and should start at once; the Nexcode opinion must be settled before the risk and valuation disclosure can be finalised; and the Zhonghai diversification plan and revised financial model are needed to protect the profit test comfort. We recommend running these workstreams in parallel, with the board and governance restructuring (which is entangled with the investor exit) begun early, and with contingency arrangements identified for each critical path item.

9 Professional Considerations

Finally, two matters of our own position deserve emphasis. We should confirm at the outset that neither we nor the syndicate has a positional conflict, for instance any relationship with Nexcode or with an exiting investor, and address anything that emerges. And we should keep in mind that our reliance on the Company's instructions and on the experts is not unconditional: where the true grounds for the Zhonghai termination or the real state of the matrimonial proceedings remain doubtful, we must probe, insist on primary documents, escalate as necessary, and be prepared to decline to sign if our doubts cannot be resolved. The filing date is driven by the verification being properly completed, not by client pressure.

10 Recommendation and Next Steps

We recommend that the syndicate proceed on the basis that this is a viable but complex listing whose feasibility depends on satisfactorily ring fencing the matrimonial risk, confirming the profit test on a Zhonghai adjusted basis, obtaining a supportive patent opinion or a workable alternative, and clearing the VIE related PRC regulatory steps. As immediate next steps we propose commissioning the PRC law and family law opinions and the independent patent opinion, instructing the reporting accountants on the adjusted financial scenario, initiating the CSRC and cybersecurity workstream, and convening a syndicate call once those opinions are in hand to reassess the timetable and the required underwriting protections.

We are happy to discuss any aspect of the above at your convenience.
