TAXWARE Receives Exclusive License From Mobil Oil to Distribute Excise System for Payments--ESP--; Tax Compliance Software Generates Excise Tax Returns for Petroleum Fuel Industry.

SALEM, Mass.--(BUSINESS WIRE)--March 30, 1999--TAXWARE International, Inc., a leading software developer of worldwide tax compliance systems, announced today the release of the Excise System for Payments (ESP), a comprehensive commercial excise tax return software package designed specifically for the petroleum fuel industry. ESP was developed by Mobil Oil Corporation (NYSE:MOB), a major international energy company that has granted TAXWARE the exclusive license to distribute the software and support ESP customers.

ESP is designed to meet the needs of all major, independent, and large distributors in the petroleum industry by providing a commercial excise tax compliance software package. The software includes a tool to automate and simplify excise tax reporting and filing processes with significant savings in time and money. Oil companies will benefit by using the software, as they must file numerous returns per year. The product offers additional benefits, including a reduction in the manpower required to perform tax-related tasks, improved accuracy, and associated cost savings. ESP users will no longer need to use internal patchwork software packages that provide solutions that are half automated and half manual.

"The license agreement with Mobil came at precisely the right time," said Dan Sullivan, TAXWARE's CEO. "Our developments on the excise tax front complement ESP and provide an opportunity to begin this relationship with Mobil. As a result of our agreement, the significant need for an excise tax reporting system in the oil industry is now fulfilled."

ESP goes beyond the previous methods of in-house developed software or manual processes to comply with excise tax return requirements. It is capable of handling federal and state taxing jurisdictions in the United States, and is Year 2000 compliant. In addition, ESP tracks all transactions, produces automated schedules, allows for easy reversing adjustments, provides easy transfer between schedules, offers query capabilities, complies with multiple taxing authorities, automates inventory and accrual reconciliations, consolidates monthly balancing, and enables lock-out of adjustments.

A stand-alone system, ESP is PC-based and operates on Windows 95, 98, NT and 3.1.
