Exhibit 99.4

Email from Duane Andrews to QinetiQ North America Operations, LLC Employees

January 22, 2007

Colleagues:

It is with great excitement that today I can deliver the news that QinetiQ North America Operations will be acquiring Analex Corporation. Pending regulatory approval, we will make an offer to acquire all of the outstanding equity ownership of Analex. Once accomplished, Analex will join the other QinetiQ North America subsidiaries: Apogen, Foster-Miller, OSEC, PSI, and Westar, in providing world-class technology and responsive solutions to our customers.

Analex (www.analex.com) is headquartered in Fairfax, Virginia, with 11 locations around the U.S. Analex specializes in providing innovative information technology, aerospace engineering and security and intelligence support services for defense, intelligence and space programs. Principal customers include the Missile Defense Agency (MDA), U.S. Navy (SPAWAR), DARPA, U.S. Army and NASA. Analex is also well positioned with intelligence customers, some of whom the company has supported for more than 20 years. Analex employs approximately 1,100 people, the majority of which hold U.S. DoD security clearances.

Once the deal closes (expected around March 31), we will bring Analex into the ongoing process of integrating the QinetiQ North America companies into a single company that maintains the agility and entrepreneurial spirit of a small business by both avoiding bureaucracy and encouraging personal initiative while also putting in place a structure that enables us to take advantage of the stability, scale and personnel/technical depth of a larger company.

Please join me in welcoming Analex to the QinetiQ North America family. Their customers and capabilities better enable both our growth and our ability to provide expanded career opportunities for all employees.

Duane Andrews
