Exhibit 4.3 - Form of Invoice and Data Feed

This document is Exhibit 4.3, a Form of Invoice and Data Feed for PennDOT's Mainframe Services RFP 3525R03, issued by the Pennsylvania Department of Transportation. The exhibit establishes the standardized invoice format that the service provider must utilize for billing purposes. The invoice structure accommodates multiple service categories including mainframe services (CPU hours, specialty engine resources, allocated application DASD, and VTS tape storage), mainframe software (Broadcom, DCR, Levi Ray and Shoup, Precisely, SAS, Silver Bay, and Tone products), transition deliverables, Request for Solution (RFS) deliverables, rate card services, pass-through expenses, and server services (RedHat Enterprise and Windows Server operating systems, server support, disk storage, backup and recovery, and virtualized cores and memory).

The invoicing methodology employs resource unit charges with variable rates applied to billable units, supplemented by Professional Services Agreement (PPA) amounts for certain service categories. The invoice format includes detailed worksheets for year-to-date reporting organized by month, supplier invoice details for CPU hour usage (capturing LPAR usage, occurrences, usage type, and application information), and supplier invoice details for storage resources (documenting quantity, unit of measure, invoice date, and high-level qualifiers). PennDOT explicitly reserves the right to modify the invoice form during the steady-state operations phase based on departmental requests and evolving operational needs.
