Lexar LockTight Security Technology Now Supported by the Nikon D200 Digital SLR Camera

A Perfect Combination for Security-Conscious Organizations Requiring the Flexibility of a Mid-Range, Feature-Rich Digital SLR Camera

FREMONT, Ca., November 21, 2005 - Lexar Media, Inc. (Nasdaq: LEXR), a world leader in advanced digital media technologies today announced that its LockTight technology will be supported in the Nikon D200 creating an ideal solution for photographers who want to fully utilize the advanced feature set in this new camera, including security functionality and burst mode shooting. Lexar Professional LockTight CompactFlash is a unique security technology that allows photographers and organizations to control access to information stored on the user's memory cards. Following full support in the Nikon D2X and D2Hs digital SLR cameras, the new Nikon D200 is the most affordable digital camera that includes built-in LockTight functionality.

"Security and controlling access to digital images continues to be a critical feature for vertical markets such as law enforcement, insurance, medicine or government. With LockTight, Lexar is offering a unique secure digital imaging solution for these markets," said John Omvik, director of professional product marketing, Lexar. "With the introduction of the D200, photographers and organizations in these markets now have three different Nikon cameras to choose from with varying feature sets and price points," he added.

Beyond security, the Lexar Professional CompactFlash with LockTight delivers a minimum sustained write speed capability of 80X, enough to take advantage of the D200's burst mode of 5 frames per second without delays in writing the data to the memory card (Lexar defines "X" within its speed-rating system as equivalent to a minimum write speed capability of 150 kilobytes per second). Any Lexar Professional CompactFlash card used with a Nikon D200 digital SLR camera is the ideal combination for shooting at weddings, sporting events or any venue where missing the perfect image is not an option.
'The comprehensive feature set of the D200' including the unique LockTight compatibility and functionality" will appeal to many professionals around the world," said Kazuyuki Kazami, General Manager of Marketing, Nikon Corporation. "Among the D200's target customer base are organizations that have a real need to protect their content, demonstrate a chain of evidence and restrict access to confidential or sensitive image data. Lexar's LockTight system offers us a unique way to address these requirements from our vertical market customers," he added.

How LockTight Works
The combination of Lexar Professional CompactFlash with LockTight and Lexar's custom LockTight software creates a security solution ideal for photographers in fields such as forensic photography, scientific research, military and law enforcement. When used in conjunction with a camera that supports the LockTight system, access to the digital content stored on a LockTight card is restricted to authorized users and authorized cameras through card level, 160 bit authentication. Once the card has been registered to users and cameras, it will only work in those specific cameras and can only be accessed on a PC or MAC by those users with the login information established by the system administrator. A Lexar Professional CompactFlash Reader completes the security solution, as only the user's registered cameras and Professional CompactFlash Readers can recognize a secured LockTight card. LockTight cards that are not secured operate as normal cards.

When used in conjunction with a camera that supports the LockTight system, LockTight CompactFlash employs a unique strategy to protect data, and, as a result, LockTight cards are always 'locked.' A computer or camera cannot read or write data to/from a LockTight card until a critical authorization process takes place between the LockTight card and the host computer or host camera. This authorization process is where the 160-bit HMAC SHA-1 hash algorithm is employed.

Lexar Professional LockTight CompactFlash cards are currently available at photo-specialty stores and through key market value added resellers in capacities of 512MB and 2GB. More information on Lexar's professional products can be found at www.lexar.com/dp.
