The SaaS modules listed in Exhibit A are provided as bundled infrastructure functionality, and the Participant's right to access and utilize such modules is co-extensive with the IRU Term.

### 2.3 Bundled Nature of IRU

The Infrastructure IRU and SaaS IRU are granted as a single, unified instrument. The Participant may not separate, unbundle, or treat the Infrastructure IRU and SaaS IRU as distinct rights. The IRU is a single, indivisible right of use that encompasses both infrastructure access and embedded SaaS functionality.

### 2.4 Non-Transfer-of-Title

The IRU granted hereunder is a right of use, not a transfer of title. DBIS retains all ownership, title, and interest in and to the infrastructure, systems, software, and related intellectual property. The Participant acquires no ownership interest, equity interest, or proprietary rights in DBIS infrastructure, systems, or intellectual property by virtue of this Agreement.

### 2.5 Technical Infrastructure Architecture

The DBIS infrastructure is deployed using a **Proxmox VE LXC (Linux Container) deployment architecture**, provided through Sankofa Phoenix Cloud Service Provider. The technical architecture includes:

(a) **Container-Based Infrastructure**: Infrastructure components are deployed as isolated LXC containers on Proxmox VE hosts, including:
    - Besu Sentry nodes for blockchain P2P network connectivity
    - FireFly Core for event listening and transaction orchestration
    - FireFly Database for state persistence
    - Monitoring and observability services

(b) **Network Architecture**: Private network segments using Proxmox bridges or SDN VLANs, with strict network segmentation and firewall enforcement to ensure security and isolation.

(c) **High Availability**: Multi-sentry patterns, active/passive FireFly configurations, and database HA options to ensure service continuity and reliability.

(d) **Security and Key Management**: Secrets and keys stored outside container images, mTLS enforcement between services, and comprehensive hardening measures.

The detailed technical architecture, including container topology, resource sizing, networking, security, and deployment procedures, is set forth in **Exhibit C (Technical Architecture - Proxmox VE LXC Deployment)** and the comprehensive technical architecture document referenced therein.

### 2.6 Scope Limitations

The scope of the IRU is subject to:

## PART VIII: ACCOUNTING & REGULATORY TREATMENT

### 8.1 Accounting Treatment

The IRU granted under this Agreement should be treated for accounting purposes as a **capitalized intangible asset**, not as an equity investment or security.

The IRU should be recognized as an intangible asset at cost, which includes:
- The IRU Grant Fee (if any);
- Direct costs associated with obtaining the IRU (legal fees, due diligence costs, etc.);
- Other directly attributable costs.

#### 8.1.2 Amortization
The IRU should be amortized over the IRU Term on a straight-line basis, unless another method better reflects the pattern of economic benefits. The amortization period should not exceed the IRU Term.

The IRU should be tested for impairment in accordance with applicable accounting standards (e.g., IAS 36, IFRS, or local GAAP). Indicators of impairment may include:
- Material breaches or termination events;
- Significant changes in DBIS operations or financial condition;
- Regulatory changes affecting IRU value;

- SWIFT membership and access rights;
- TARGET2 participation rights;
- CLS Bank participation rights;
- Other financial infrastructure access arrangements.

This classification is consistent with:
- The non-equity, non-commercial nature of DBIS;
- The infrastructure and utility function of DBIS;
- International financial infrastructure precedent;
- Regulatory treatment of similar arrangements.

### 8.5 Regulatory Capital Treatment

For regulatory capital purposes, the IRU should be treated as:

- Not an equity investment or security;
- Subject to applicable limits on intangible assets for regulatory capital purposes.

Participants should consult with their primary regulator to confirm the appropriate regulatory capital treatment.

### 8.6 Tax Treatment

Tax treatment of the IRU will depend on applicable tax law in the Participant's jurisdiction. Participants should consult with qualified tax advisors regarding:
- Deductibility of IRU Grant Fees and ongoing costs;

### Network Architecture

- **Private Network Segments**: Proxmox bridges or SDN VLANs for container communication
- **Network Segmentation**: VLAN-based segmentation (Management, Private Services, DMZ)
- **Security Zones**: Strict firewall enforcement and network isolation
- **External Access**: Only Besu Sentry nodes have controlled external exposure

### Resource Sizing (Baseline)

**Besu Sentry Node**:
- vCPU: 4 cores (pinned)
- RAM: 8–16 GB
- Disk: 200–500 GB (fast I/O)

**FireFly Core**:
- vCPU: 2–4 cores
- RAM: 4–8 GB
- Disk: 50–100 GB

**FireFly Database**:
- vCPU: 2 cores
- RAM: 4–8 GB
- Disk: 100–200 GB (IOPS prioritized)

### High Availability

- **Multi-Sentry Pattern**: 2+ Besu Sentry nodes on separate Proxmox hosts
- **FireFly HA**: Active/passive FireFly Core configuration
- **Database HA**: Optional PostgreSQL primary/replica with synchronous replication

### Security

- **Key Management**: Secrets stored outside container images, mounted as read-only volumes
- **mTLS Enforcement**: Mutual TLS between FireFly and Besu
- **Network Isolation**: No lateral container access by default
- **Hardening**: Comprehensive hardening checklist for hosts, containers, and networks

### Deployment

- **Provisioning**: Automated deployment and provisioning flow
- **Lifecycle Management**: Snapshot-based rollback, rolling restarts, live migration support
- **Version Control**: Version-pinned binaries with upgrade procedures
- **Acceptance Tests**: Comprehensive deployment acceptance tests
