2. Federal law empowers the United States Government to license its patents toprivate parties for commercialization as well as for enforcement of the patent without the
United States as a party. 37 C.F.R. 404.5(b)(2). By doing so, the government can use
market forces to better capitalize on its technologies, the way a private party would. In
addition, a license agreement can give the private licensee the proper incentives to protect
the governments intellectual property from theft, a task often handled better by a private
entity.

NETWORK SIGNATURES LICENSES THE NAVYS TECHNOLOGY
7. On April 23, 1996, the United States Patent and Trademark Office duly andlegally issued United States Patent No. 5,511,122 (the 122 Patent), entitled
Intermediate Network Authentication.
8. The 122 patent claims, among other things, a critical method ofauthenticating a computer in which a private electronic key is used, together with a
validating public electronic key, to create a cryptographic signature; the cryptographic
signature is transmitted in at least one packet to the validating computer; and the signature
is verified by the validating computer, using its private key and the public key of the
computer to be authenticated. This authentication method allows for the safe and secure
communication of sensitive information, such as personal, banking, commercial, financial
and other information, as is transmitted between computers by Defendant and its
employees, customers, vendors, and business partners.
9. The 122 Patent is owned by the United States of America, represented by thSecretary of the Navy. To allow enforcement, commercialization and protection of this
patent and the technology it represents, in September 2004, the United States Navy entere
into an exclusive license agreement with Metrix Services, Inc. (the Exclusive License
Agreement) expressly granting Metrix Services the exclusive right to practice, enforce,
and sublicense the 122 Patent, among other rights, subject to the general limitations
imposed by federal law. A true and correct copy of the Exclusive License Agreement is
attached hereto as Exhibit A and incorporated here by reference. With the express approv
of the United States Navy, Metrix Services transferred its entire right, title, and interest in
and to the 122 Patent to Network Signatures on February 14, 2006. A true and correct
copy of the First Amendment to the Exclusive License Agreement, which, among other
things, approved the assignment of the Exclusive License Agreement to Network
Signatures, is attached hereto as Exhibit B and incorporated here by reference. A true and

and incorporated here by reference.
10. In accordance with its rights under the Exclusive License Agreement, NetwoSignatures has begun the commercial development of a product, known as EasyConnect,
that practices the 122 Patent. Network Signatures has demonstrated the product to NRL
personnel and has received NRLs recognition of its development efforts. A true and

this and is attached as Exhibit D and incorporated by reference here.
