Governing law
Republic of South Africa · Courts of Johannesburg

This Agreement describes the King-Nel Refineries private digital exchange, establishes the rights and responsibilities of participating clients, and sets the standards for issuing, safeguarding, transferring, and redeeming Digital Gold Tokens. It combines the platform explanation with binding client participation terms upon acceptance under Section 17.

The central commitment is full physical backing: each outstanding Digital Gold Token must correspond to its stated quantity of physical gold in audited reserves. After opening an approved account, clients receive access to the related supporting documentation before they commit funds to a token purchase.

1

Parties and platform licensing

This Agreement is between King-Nel Refineries ("King-Nel" or the "Company"), identified in Schedule A, and the individual or legal entity accepted as a client (the "Client"). An authorized representative accepting for an entity confirms authority to bind that entity. "Platform" means the King-Nel branded digital account, wallet, private ledger, and related services made available under this Agreement.

King-Nel has obtained a white-label platform license from Vanguard International Systems, Corp. ("VIS"), the Global Master Distributor of the real asset tokenization and interchange software. The license authorizes King-Nel to operate its branded platform within the scope of the applicable license agreement. VIS is the platform licensor and distributor; the underlying software ownership and technical support responsibilities remain governed by the applicable technology agreements.

King-Nel is responsible to its Clients for its token program, reserve representations, client disclosures, account administration, and contracted gold redemption obligations. A technology license does not itself appoint VIS as a gold custodian, auditor, escrow agent, bank, card issuer, or guarantor. Any such separate appointment must be documented expressly. King-Nel remains responsible for its own contractual obligations when it engages service providers.

"Gold Sika" is a trademark brand of King-Nel and acts as the transaction brand vehicle for King-Nel's gold-backed stable-token tools and products. References to Gold Sika in this Agreement, on the Platform, and in related documentation identify King-Nel's branded token program and do not create a separate legal entity, issuer, custodian, or obligor. King-Nel remains the contracting party and is solely responsible for the obligations recorded in this Agreement, and a Client's rights are enforceable against King-Nel regardless of the brand used.

2

Private platform architecture

The Platform uses a private, serialized ledger rather than a public blockchain. Approved Clients can hold and transfer eligible tokens within the authorized community and, where enabled, through the participating platform interchange. Separate branded platforms may operate within the ecosystem, subject to their own permissions and compliance controls.

The term "decentralized" describes the ecosystem of separately administered participating platforms. It does not mean that King-Nel has no operator, that records are public, or that transactions are outside applicable law. Privacy, electronic recordkeeping, and real-time ledger processing do not remove market, custody, operational, or regulatory risks.

3

Token classes and Client entitlements

A "Digital Gold Token" or "DGT" is a serialized digital record of the Client's entitlement to a fixed quantity of fine physical gold. The precise gold weight per token, purity standard, custody arrangement, and redemption terms must be stated in the applicable Token Series Record in Schedule A before issuance. A gram or ounce denomination must identify fine weight, and an ounce denomination must specify a troy ounce.

Gold and USD balances must remain separately identifiable. King-Nel must not describe a gold token as permanently worth one US dollar, substitute USD for required physical gold reserves, or count the same asset against two token liabilities. Converting between classes is a separate transaction at an accepted quotation.

A ledger entry evidences the quantity and contractual rights recorded for the Client. Whether the Client also owns identified bars, an undivided beneficial interest, or another legally enforceable property interest must be established by the custody and title documents disclosed before purchase. A token label or bar serial number alone does not create a trust, perfected security interest, or protection from insolvency.

4

Full physical gold backing

King-Nel represents and undertakes that all issued and outstanding DGTs are backed at all times by 100% physical gold held in audited reserves. Eligible fine gold weight must equal or exceed the aggregate fine gold weight represented by outstanding DGTs. Coverage is measured in gold weight, not merely by the cash value of gold or the Company's total assets.

Eligible reserve gold must exist, have verified purity and lawful provenance, be held under documented custody arrangements for the token program, and be available to satisfy the disclosed Client entitlements. Unmined deposits, expected production, receivables, purchase orders, gold derivatives, and uncompleted gold purchases do not qualify as physical reserves.

Reserve gold must not be sold, pledged, lent, rehypothecated, or otherwise encumbered for King-Nel's operating debts or another person's obligations. Outstanding DGT liabilities must never exceed eligible reserves. No reserve substitution or withdrawal may impair Client entitlements or the required coverage.

5

Custody, reconciliation and independent verification

Before any DGT is issued, King-Nel must establish the custody and title structure, identify the reserve custodian and vault jurisdiction, obtain the supporting bar inventory and assay records, and make a current independent reserve audit report available in the Client documentation portal. The reserve representation is a continuing obligation supported by evidence, not merely a marketing description.

The reserve records must identify each bar or lot, its unique serial number or traceable identifier, gross weight, fineness, calculated fine gold weight, location, custodian, and allocation status. Where Clients share an identified pool, the records must explain how individual entitlements reconcile to the pooled inventory without allocating the same fine gold weight twice.

King-Nel must reconcile outstanding token liabilities to eligible gold inventory each business day and before every new issuance or reserve withdrawal. Appropriate controls must separate issuance approval, custody instructions, and reconciliation review. Tokens may be issued only after cleared purchase funds, completed compliance checks, and confirmation that the required gold is in eligible custody.

An independent, suitably qualified auditor must conduct reserve verification at least annually, with interim independent verification at the frequency disclosed in Schedule A. The engagement must address physical existence or reliable custody confirmation, fine weight and purity evidence, custody and title documentation, encumbrances, and reconciliation against all outstanding token liabilities. Any scope limitations, qualifications, exceptions, and reliance on third-party confirmations must be stated clearly.

The portal must identify the auditor, reporting date, period covered, procedures performed, conclusions, and report limitations. A custody confirmation, bar list, assay certificate, or management declaration must be described accurately and must not be presented as an independent audit. A reserve audit is evidence as of its stated date; it is not a guarantee of future solvency, uninterrupted access, or the market value of gold.

King-Nel must disclose the applicable custody insurance, named insured or beneficiary arrangements, material exclusions, policy limits, deductibles, territorial scope, and claim procedures. No statement of insurance may exceed the actual coverage. Reserve segregation and insurance do not eliminate loss or insolvency risk.

If a reserve shortfall, material title defect, invalid permit, or materially adverse audit finding arises, King-Nel must promptly suspend affected new issuance and reserve withdrawals, investigate, and take corrective action at its expense. It must notify affected Clients without undue delay, subject to lawful restrictions, and provide an explanation, remedial plan, and progress updates. Any restriction on transfers or redemption must be necessary, proportionate, legally justified, and subject to ongoing review.

A shortfall does not authorize King-Nel to reduce the fine gold entitlement per token, impose an undisclosed loss allocation, or release itself from liability. Existing Client rights survive remediation. If coverage or lawful operation cannot be restored, King-Nel must implement an orderly redemption or wind-down process consistent with Client rights and applicable law.

6

Client access to supporting documentation

Once a Client opens an account and completes required identity and eligibility checks, King-Nel shall provide secure access to all available documentation relevant to that Client's token program. Access must be provided before the Client is asked to purchase DGTs and must continue while the account remains open, subject to lawful access controls.

Each document must show its date, issuer, scope, and status. Expired, superseded, pending, unavailable, or not-applicable documents must be identified accordingly. King-Nel must not present a permit application as an approval, an escrow letter as a complete trust arrangement, or a certificate as proof of facts outside its stated scope. Material missing evidence must be disclosed and cannot be replaced by an unsupported assurance.

Reasonable redactions may protect personal information, commercial terms, and physical security. They must not conceal material facts about reserve coverage, Client rights, custody, or permit validity. Where necessary, King-Nel shall offer controlled inspection or independent verification of material underlying evidence, subject to lawful confidentiality arrangements.

Clients may request clarification and retain permitted copies for their records and advisers. Material changes must be notified through the portal and the registered contact channel. Viewing a document is not a waiver of rights or acceptance of inaccurate information. Documentation access does not imply that any government, auditor, VIS, or payment network endorses the program.

7

Account opening and account services

Individuals must have legal capacity and meet the applicable eligibility criteria. Entity Clients must identify their legal existence, authorized representatives, and beneficial owners. King-Nel may request identity, address, source-of-funds, source-of-wealth, tax-residency, and transaction-purpose information as appropriate. Account opening does not itself create a token balance or guarantee access to every service.

After approval and acceptance, the Client receives a digital account and wallet showing the token class, quantity, relevant gold weight, transaction history, and applicable valuation information. Statements and confirmations must distinguish an indicative market value from a firm executable quotation. The Client must review entries promptly and report suspected errors or unauthorized activity without undue delay.

Business Clients may use authorized operating accounts or subaccounts to organize projects, treasury functions, and payment permissions. Role-based approvals and account limits may be configured where supported. An administrative subaccount is not, by itself, a separate legal trust, escrow, client-money account, or insolvency-protected estate.

The Platform is intended to support ongoing online access, but service interruptions may occur. King-Nel shall maintain reasonable security, backup, incident-response, and business-continuity arrangements and disclose planned maintenance and material disruptions. Any contractual service levels must be documented separately; no uninterrupted availability guarantee is created by describing the service as accessible around the clock.

8

Payment cards, escrow and external payment services

Where available and approved, a Client may receive a physical or virtual branded card through an authorized issuing or program partner. Card eligibility, network acceptance, geographic restrictions, fees, transaction limits, ATM access, and dispute rights are governed by the applicable card terms. Availability must not be described as universal.

A merchant ordinarily receives fiat payment through the card network. Spending a DGT balance requires an authorized gold-to-fiat conversion at the applicable disclosed price, spread, and fees. A card purchase does not mean that merchants or ATMs accept or dispense DGTs or physical gold. The Company must explain whether conversion occurs before authorization, at authorization, or during settlement.

An escrow service may be used only under a separate written escrow agreement identifying the agent, assets, beneficiaries, release conditions, and dispute procedures. A conditional ledger hold is not automatically a legally segregated escrow or trust. The escrow letter and underlying agreement must be available under Section 6. King-Nel must not imply independent escrow protection where the arrangement is solely an internal account restriction.

Bank transfers, ACH, wires, cash collection, foreign exchange, and other external services are available only through approved channels where legally permitted and operationally supported. The Client shall receive the provider identity, material terms, and charges before use. External clearing times, reversals, cut-off times, and compliance reviews may differ from internal ledger processing times.

9

Purchase, valuation, transfer and redemption

Before accepting a purchase, King-Nel must disclose the token class, quantity, gold weight, price source and timestamp, spread, currency conversion, total fees, applicable taxes, and settlement conditions. Only designated payment instructions verified through the secure Platform may be used. Funds received before completion must be accounted for and handled under the disclosed funding terms; receipt alone does not authorize unsupported token issuance.

The fiat value of a DGT reflects its fine gold weight and the quoted gold price, adjusted for disclosed spreads, fees, and exchange rates. Gold prices can fall. Full physical backing is a reserve standard and does not guarantee principal in USD, a fixed return, an inflation hedge, or a profit. A separately activated USD token is subject to its own reserve and redemption terms.

Internal transfers may be recorded in real time after authentication, balance checks, authorization, and applicable compliance controls. Interchange transfers require compatible token classes and receiving-platform approval. Ledger completion does not guarantee simultaneous bank settlement or remove rights arising from fraud, mistake, court order, or mandatory payment rules. Corrections must preserve an audit trail.

The Client may request redemption of eligible DGTs for the corresponding physical gold, or sale and payment of the net fiat proceeds where that option is offered. Before the Client confirms the request, King-Nel must disclose minimum redemption sizes, permitted bar sizes, handling and fabrication costs, location or delivery options, shipping and insurance charges, applicable taxes, and expected completion times. These terms must be completed in Schedule A before issuance.

A fiat redemption of DGTs is a gold sale at the accepted quotation, not redemption at a guaranteed one-dollar value. King-Nel must disclose quote validity, any price-lock conditions, payment currency, and settlement timeframe. The Client must approve any changed quotation before execution unless a previously accepted order expressly authorizes it. Undisclosed spreads and retroactive charges are prohibited.

Upon a valid redemption request, the relevant tokens may be locked to prevent transfer. Cancellation of the tokens and release of reserve gold must be coordinated so that neither an unbacked outstanding token nor a duplicate claim is created. The Client's redemption claim remains enforceable until the contracted gold delivery or payment is completed. King-Nel must provide a final reconciliation and confirmation.

Redemption may require identity re-verification, lawful source checks, delivery verification, or compliance with export, import, sanctions, or court requirements. A delay must be explained to the extent permitted by law, with a revised estimate and available options. No provision permits indefinite discretionary withholding or the use of redemption reserves for Company operating expenses.

Fees must be funded separately or charged through an expressly authorized balance adjustment that is recorded transparently. Storage or service charges must not silently reduce the gold weight per outstanding DGT. Any authorized sale or cancellation to pay charges must state the resulting token balance and gold entitlement and preserve the full-backing standard.

10

Professional accounts and branded deployment

Professional accounts may provide administrative dashboards, reporting, business payment workflows, account permissions, and approved integrations. The commercial scope, service levels, pricing, support, data responsibilities, and implementation obligations must be documented in a separate professional services agreement.

White-label software, sublicensing, APIs, and branded deployment may be offered only to the extent expressly authorized under King-Nel's license from VIS and any required third-party approvals. This Agreement does not grant Clients a software sublicense, ownership of the software, authority to issue tokens for others, or a right to reproduce VIS or King-Nel intellectual property.

Physical cards, point-of-sale devices, or other hardware services require separate availability, procurement, issuer, and network arrangements. King-Nel must not promise hardware-as-a-service, payment-network sponsorship, or unlimited geographic deployment unless the relevant arrangements are in place.

Each professional program must identify its operator, issuer, reserve obligor, custodian, and service providers. Participation in a shared technology ecosystem does not pool reserves across companies or make one platform responsible for another platform's liabilities unless an express agreement establishes that responsibility.

11

Compliance and permitted markets

King-Nel shall obtain and maintain the registrations, permits, licenses, and approvals legally required for the services it actually provides in each relevant jurisdiction. Its software license from VIS is a contractual technology license and is separate from any governmental authorization. Services must be restricted where the required legal basis or provider arrangements are absent.

Private membership, gold backing, a non-blockchain ledger, and the terms "utility token" or "non-crypto" do not, by themselves, establish an exemption from financial, securities, commodities, payments, custody, exchange-control, consumer, or tax law. Regulatory treatment depends on the actual rights, arrangements, activities, and jurisdictions involved. This Agreement makes no categorical determination that a token is or is not a security.

King-Nel shall conduct risk-based know-your-customer and anti-money-laundering controls, sanctions screening, beneficial-ownership verification, ongoing monitoring, record retention, and legally required reporting. Clients must cooperate with reasonable requests. King-Nel may reject, hold, or restrict a transaction when reasonably required by law or supported compliance controls, without disclosing legally protected reporting information.

Gold must have documented lawful provenance. Refining, trading, custody, export, and import activities must comply with their applicable requirements. A permit issued for one entity, activity, or jurisdiction must not be represented as authorization for another. A certificate of analysis does not establish every element of lawful title or regulatory compliance.

DGTs under this Agreement do not promise interest, dividends, profit sharing, or a guaranteed investment return. Any separately proposed investment token or managed investment program requires separate legal analysis, offering documentation, and required approvals before solicitation or sale. Clients remain responsible for their own tax reporting, subject to King-Nel's statutory reporting duties.

12

Client duties, security and confidentiality

The Client shall provide accurate information, keep authorized-user details current, use the Platform lawfully, safeguard credentials, use available multi-factor authentication, and promptly report compromise. The Client shall not impersonate others, bypass controls, manipulate records, conceal beneficial ownership, or use the Platform to facilitate unlawful transactions.

King-Nel shall maintain access controls, transaction logs, appropriate encryption, controlled staff permissions, and reasonable measures against unauthorized changes. The Client must verify payment instructions and high-value requests through approved channels. No security description is an assurance that fraud, cyberattack, or operational failure is impossible.

King-Nel may process identity, transaction, device, and compliance information for account administration, security, service delivery, and legal obligations. It must provide a privacy notice identifying the responsible entity, purposes and lawful grounds, relevant recipients, cross-border transfers, retention periods, and available rights and complaint routes. Blanket consent is not a substitute for another lawful basis where one is required.

Transaction records are private and are not published on a public blockchain. Confidentiality remains subject to disclosures to authorized service providers, auditors, courts, regulators, and other recipients where lawful. King-Nel shall limit access to what is appropriate for the purpose and comply with applicable data-protection and incident-notification duties.

Clients shall use nonpublic documentation for lawful verification, advice, and account purposes and protect third-party personal or security-sensitive information. This duty does not prevent lawful complaints, truthful disclosures to authorities, or confidential consultation with professional advisers.

13

Material risks and limitations

Market and currency risk. Gold can decline in price, and exchange-rate movements, spreads, fees, and taxes can reduce redemption proceeds. Gold backing does not preserve a fixed purchasing power or guarantee that the Client will recover the amount originally paid.

Custody and legal risk. Loss, theft, fraud, defective title, insurance exclusions, custodian failure, and insolvency can impair recovery. The effectiveness of segregation and Client ownership depends on the executed legal arrangements and applicable law. An escrow letter, audit report, or serialized token is not government deposit insurance.

Liquidity and operational risk. Physical redemption may be subject to minimum bar sizes, vault procedures, logistics, and border requirements. Fiat settlement depends on available buyers, banking channels, and compliance. Outages, cyber incidents, pricing errors, or provider failure may delay access or settlement. Internal ledger speed does not eliminate these risks.

Regulatory and geographic risk. Law, supervisory action, sanctions, tax treatment, or service-provider restrictions may affect available services and cross-border transfers. These disclosures explain possible risks; they do not excuse King-Nel from its reserve, disclosure, compliance, or redemption obligations.

14

Responsibility, complaints and account closure

King-Nel is accountable for the accuracy of its own representations and performance of its contractual duties. Nothing excludes liability for fraud, willful misconduct, gross negligence, unauthorized reserve use, or any liability that cannot lawfully be excluded. Nothing relieves King-Nel of its obligations to account for Client assets or complete valid redemption obligations. No general waiver of statutory consumer rights is created.

A Client may submit complaints, disputed entries, or suspected unauthorized transactions through the contact channel in Schedule A. King-Nel shall acknowledge receipt within five business days and aim to provide a substantive response within twenty business days, unless a shorter mandatory period applies. If further investigation is required, it shall explain the reason and provide a progress estimate, subject to lawful confidentiality restrictions.

King-Nel may suspend access where reasonably necessary for security, legal compliance, a material breach, or orderly maintenance. Restrictions must be proportionate and reviewed. The Client may request account closure and redemption of eligible balances. Closure or suspension does not extinguish gold entitlements, payment obligations, access to required records, or accrued claims. Assets subject to lawful restraint must be accounted for until release is permitted.

If the technology license, a required authorization, or a critical custody or payment arrangement ends, King-Nel shall give affected Clients lawful notice and implement a continuity or orderly wind-down plan. It must preserve records, reserve protection, and available redemption mechanisms. A third-party failure or force-majeure event does not permit diversion of reserves or cancellation of Client entitlements.

15

Governing law and dispute resolution

This Agreement is governed by the laws of the Republic of South Africa, without limiting mandatory protections applicable to a Client elsewhere. The parties shall first seek to resolve a dispute through the complaint process. Subject to nonwaivable rights and any later written agreement, the competent courts in Johannesburg, South Africa shall have nonexclusive jurisdiction. Either party may seek urgent protective relief where legally available.

No Client is required by this Agreement to waive access to a regulator, ombud, competent consumer forum, or other mandatory remedy. Arbitration applies only if separately and validly agreed in writing. Notices may be delivered through the secure portal and the registered contact details, with appropriate records of dispatch and availability.

16

Interpretation, changes and continuing rights

This Agreement and the accepted Schedules govern participation. Mandatory law prevails. A separately signed escrow or custody agreement governs the legal treatment of the assets it covers, without silently displacing King-Nel's obligations. A Token Series Record may supply operational details but may not reduce the full-backing or core disclosure commitments in this Agreement.

Material amendments require prior notice and affirmative acceptance where required by law. A change cannot retroactively reduce an existing gold entitlement, excuse an accrued breach, or impose an undisclosed charge. Severability preserves the lawful remainder; a failure to enforce a term is not a waiver. Recordkeeping, confidentiality, asset-accounting, redemption, and accrued liability provisions survive termination to the extent relevant.

17

Acceptance and formation of the Agreement

The Client accepts this Agreement by signing below or by an affirmative electronic acceptance process that displays this Agreement and the applicable completed Schedules, permits the Client to retain a copy, and records the Client's deliberate agreement. King-Nel accepts the Client through an authorized signature or a recorded approval notice expressly referring to the accepted version. The effective date is the later of those acceptances.

The electronic record must identify the accepting party, authorized representative where applicable, document version, applicable Schedules, and acceptance date and time. Merely viewing a page, receiving this document, or opening an unapproved account is not acceptance. No signature or electronic acceptance validates an unlawful term or waives a nonwaivable right.

Schedule A — Program disclosures and Token Series Record

King-Nel shall complete and make this record available before the first purchase in the relevant token series. Each series must have its own dated record. Blank fields do not authorize issuance. Supporting records must be accessible under Section 6; a reference must identify the actual document and version.

Token series: Digital Gold Token (DGT). Gold weight per token: 1/16 gram of fine gold, fine weight. Purity standard: 96% fine gold. Reserve custodian, vault jurisdiction, audit frequency, interim verification, insurance arrangements, minimum redemption sizes, permitted bar sizes, handling and fabrication costs, delivery options, shipping and insurance charges, taxes and expected completion times are stated in the completed record for the relevant series.

Schedule B — Client acknowledgment and execution

By signing or affirmatively accepting, the Client confirms receipt of this Agreement and the completed applicable Token Series Record; the opportunity to review the supporting documents and ask questions; and understanding of the distinction between full physical backing and a guarantee of fiat value or uninterrupted liquidity.

This acknowledgment does not certify the accuracy of King-Nel's records and does not release King-Nel from responsibility for its representations or obligations.
