BISYS(R) Alternative Investment Services and T-Zero Create Strategic Alliance to Provide Leading Credit Derivative Affirmation Service.

ROSELAND, N.J. -- BISYS Alternative Investment Services, a leading global provider of administrative, accounting and tax services for the hedge fund and private equity industry, today announced a new strategic partnership with T-Zero, a credit derivative market leader in trade affirmation. T-Zero provides a leading post-trade affirmation and connectivity platform for the Credit Default Swap (CDS) market.

The BISYS Alternative Investment Services partnership with T-Zero facilitates integrated processing with a system that supports the drive for automation in the fast-growing derivatives market. T-Zero provides an easily adaptable post-trade affirmation and messaging service that confirms trades prior to processing in order to ensure accurate trading details. T-Zero provides a core level of connectivity between clients, brokers and the BISYS platform that enables straight-through-processing (STP) for a key over-the-counter (OTC) investment product.

"In partnering with T-Zero, BISYS again demonstrates its commitment to clients' trading complex strategies and instruments," said Mary Lumetta, vice president of BISYS Hedge Fund Services. "We have expanded our STP model to further automate the processing of OTC products. T-Zero provides us with a consistent trade source that allows us to quickly set up and automate the processing of trade files. The integration of T-Zero into our product suite provides better operating controls

and proactively addresses issues before they become problems for both us and our clients."

"T-Zero is very excited to be partnering with BISYS in this way," said Mark Beeston, president of T-Zero. "As a major player in the derivative fund administration space, BISYS is clearly committed to improving the quality of operational processing for their clients, and we are pleased that the T-Zero affirmation process is a key part of that."
