Calgary, Alberta –  May 23, 2006 Poseidon Capital Corp. (the 'Corporation', trading symbol 'PSN' on TSXV) and its wholly owned subsidiary Acceleware Inc. are pleased to announce Non-Linear Control Strategies Inc. (NLCST) as an integrated partner. Sim_3DMax can now use the Acceleware FDTD product family, yielding a 5-10 times performance increase over traditional high-end CPUs. NLCST's Sim_3DMax" powered by Acceleware technology, enables the ultra-fast simulation of optical/imaging devices, lithography masks, and semiconductor lasers.

Significant acceleration of photonics simulations enables faster time-to-market for product companies, the ability to optimize design parameters, yielding better products, and enables engineers and organizations to cut costs and increase productivity. "We think that Acceleware's products offer an enormous speed advantage and will open new doors for Sim_3DMax", states Jerome Moloney, President of NLCST. Ryan Schneider, CTO of Acceleware adds: "We are excited about our partnership with NLCST. They are a dynamic, forward-looking company with quality products. We look forward to strengthening our relationship and continuing to add value for NLCST and its end users."

About Acceleware

Acceleware develops and markets hardware accelerators used to reduce the run-times of high-performance computing (HPC) applications such as cell-phone design, seismic data processing, nano-materials research, protein folding and drug discovery, reservoir simulation, lithography mask design, and others. Acceleware products are distributed by Computer Aided Design (CAD) and Computer Aided Engineering (CAE) software companies to end-users at the world's largest companies in a wide range of industries. A simulation that would have otherwise taken eight hours, may only take 15 minutes with Acceleware's v1.5 generation of products. The v2.0 generation will be released in the summer of 2006. Acceleware has identified the following markets for its technology: electromagnetics; energy; biomedical; fluid dynamics; molecular chemistry; industrial; and military.
