Santa Clara, Calif., September 13, 2006 -- OpSource, the SaaS experts, announced today that it has added two new customers to its quickly growing roster of Optimal On-Demand users. Ambient Software and AppStream have chosen OpSource's unique Software as a Service (SaaS) enablement and management solution.

Ambient Software's Pathworks provides policy and procedure capabilities to support users managing procedure-driven activities to help them avoid costly mistakes. AppStream, meanwhile, offers school districts and Fortune 500 customers a patented on-demand software distribution and software license management platform. This platform streams applications from a central server out to local and remote PCs in order to allow users to use them like conventionally-installed applications.

OpSource's Optimal On-Demand offering, a turnkey, scalable service delivery solution, will allow these technology pioneers to leverage a secure, reliable SaaS infrastructure, 24x7 call center support, fully managed services, application management and a 100 percent uptime guarantee to focus on cementing their place in the market. OpSource provides its customers with a low-cost entry into the SaaS world, as well as a vehicle to safe and unlimited growth going forward.

"We are the silent partner that takes away the headache and that lets software companies focus on what they do best," said Nick Blozan, senior vice president of marketing and sales. "Our customers would have to focus half of their efforts on buying equipment, hiring IT folks and a whole lot of tasks not in their corporate DNA. We are focused on helping our customers outsource areas that are mission critical to their business, but not necessarily strategic. We are focused on handling these tasks in a way that ensures that our customers achieve their business goals more quickly."

"OpSource allows us to deliver Pathworks to our customers in a way that is completely seamless to them," said Tony Nemelka, CEO & president of Ambient. "In order to succeed, we knew we needed a partner to help us maintain technological excellence and superior customer support even as we continue to pursue superiority and flexibility in addressing the evolving needs of our customers. OpSource offers the superior business model and personnel to be our partner as we continue to develop strategically as a company."

"Our customers are looking for on-demand access to applications, and OpSource has the infrastructure that will allow us to show how our customers can use software as a service from their own data centers," said Brad Rowland, vice president of marketing at AppStream. "OpSource's Optimal On-Demand model alleviates the need for us to manage delivery and availability for pilots, demos, and proof of concept evaluations. We are excited to be partnering with OpSource, a trusted and reliable partner who shares in our philosophy in delivering value through the software as a service model. OpSource's reliable and scalable hosting infrastructure allows our Global 1000 customers to try software as a service before implementing in their own data center."

OpSource's Optimal On-Demand offering, a turnkey, scalable service delivery solution, includes 24x7 call center operations under the ISV's brand, fully managed services, application management and a 100 percent uptime guarantee. OpSource's Success-Based Pricing model helps small to medium-size companies remain competitive without having to make the capital investments usually necessary when delivering a new on-demand application. The entire infrastructure is built on OpSource's patent-pending technology platform, the OptiTech Services Engine, which supports rapid integration, deployment, and monitoring of on-demand offerings.
