         Key Element of Strategic Commitment to Enterprise Networking 
                                    Market

Kanata, Ontario, December 19, 1996 -- Newbridge Networks today announced key 
strategic moves to further strengthen its position in the enterprise networking
market.  The Company announced it has signed a letter of intent with Tandem 
Computers Incorporated to acquire UB Networks, a leading supplier to the 
enterprise networking market and a subsidiary of Tandem Computers.  With this 
move, Newbridge Networks enhances its ability to deliver the advanced 
internet working products and support customers need to take full advantage of 
the Internet and intranet, as well as multimedia applications.

The acquisition of UB Networks, the industry's first independent local area 
networking (LAN) company, will provide Newbridge Networks with a significant 
addition to its own enterprise networking product and service offerings.  With 
its comprehensive product line and strong global sales and customer support, UB 
Networks has excellent relationships with Fortune 1000 companies.  The 
acquisition is expected to accelerate implementation of the Company's 
industry-leading VIVID/TM/ switched routing solution.  The enterprise hub and 
switch LAN market is expected to experience double-digit growth for the 
foreseeable future and is anticipated to approach US $24 billion by the year 
2000, according to independent market research (Dell'Oro Group 1996).

"Today's announcement further strengthens our presence in the enterprise 
networking market throughout the world," said Terence Matthews, Chairman and 
Chief Executive Officer, Newbridge Networks.  "Now, Newbridge Networks is even 
better positioned to offer customers around the world unparalleled enterprise 
networking solutions with UB Networks' proven products, sales and customer 
support, our own industry-leading VIVID product line, and products and 
applications from a number of our key affiliates such as ACC, TimeStep and 
Vienna."

UB Networks will become a wholly-owned subsidiary of Newbridge Networks.  
Christopher Brennan will continue in his present position as President and Chief
Operating Officer of UB Networks.  Mr. Brennan will work closely with Peter 
Sommerer, formerly President of Newbridge Networks, who has now been appointed 
to the position of Vice Chairman of Newbridge Networks and will become Chief 
Executive Officer of UB Networks.  Mr. Sommerer served as Newbridge President 
for six years.

"The skills and experience that Chris Brennan and Peter Sommerer each bring to 
the organization will drive the Company in its completion of an unsurpassed 
complete product, sales and service offering to the enterprise market," added 
Mr. Matthews.  "Working together, Peter and Chris will ensure a very smooth and 
effective integration of UB Networks with Newbridge."
