Aztek Networks Secures $7.5 Million in Series B Venture Financing

Latest funding to fuel new distribution channels and rollout of additional Emergency Stand Alone telecommunications products

Boulder, Colo. (Aug. 22, 2007) - Aztek Networks, a leading provider of Emergency Stand Alone (ESA) switching products, today announced the closing of $7.5 million in Series B funding. The financing was led by the Telecommunications Development Fund (TDF), a previous investor in Aztek Networks. Other existing investors, including Sequel Venture Partners and Grotech Capital Group, also contributed to the financing, along with new investor Legend Ventures. The company, which has now secured a total of $14.1 million since its formation, also announced that James Pastoriza, managing director with TDF, will join the Aztek Networks board of directors.

Launched by Aztek Networks in June of this year, the Aztek 5000S ESA switching device is the first and only open-standards, environmentally hardened and fully redundant ESA switch. The 5000S helps ensure public safety by constantly maintaining local calling capabilities and subscriber access to emergency 911 services in the event the link to the primary host switch is severed due to an accident or natural disaster. In addition, the 5000S is an ideal solution for switch collapse, whereby independent carriers can cost-effectively replace traditional legacy end-office switches and proprietary remote switching units. Since its launch just three months ago, the Aztek 5000S has received strong market recognition and is currently installed and operational within the networks of several incumbent telecommunications companies in the United States.

Providing customers with continuous access to emergency services and 911 assistance is vitally important to telecommunications operators, said James Pastoriza, managing director with TDF. Aztek Networks offers a highly focused, reliable and cost-effective solution to help operators ensure public safety and streamline their networks. With the successful launch and steady adoption of the Aztek 5000S, we are pleased to increase our support of the company as it expands its distribution channels and develops additional products that address new and emerging IP-based network services.

Were pleased to have TDF lead this latest round of funding and appreciate the support of all our investors as we continue to build Aztek Networks into a successful telecommunications network supplier, said Steven Bruny, CEO of Aztek Networks. This continued commitment by our investors, coupled with our initial success in rolling out the Aztek 5000S, further validates our vision that telecommunications operators will see solid value in our technology solutions.
