The period of performance for the base year is 1 October 2025 through 30 September 2026. • The software maintenance includes the receipt of new versions and releases of software products. • PKWare, Inc. is the OEM and the only source for software maintenance of the licensed PKWare products. • The award will include an unfunded CLIN for each contract year, to accommodate the potential need for additional PKWare licenses due to increased or new customer requirements and increased hardware capacity due to hardware tech refreshes.
