Quantum to acquire Advanced Digital Information

NEW DELHI

JUNE 3, 2006

Quantum Corp, a global leader in storage, announced a definitive agreement under
which Quantum will acquire Advanced Digital Information Corp. for approximately
$770 million. With combined revenues exceeding $1.2 billion over the last four
quarters, the two companies are joining to provide customers with the most
comprehensive and integrated range of solutions for securely storing, managing,
protecting and recovering their data in open systems IT environments. Bringing
the two companies together will enable Quantum to deliver greater innovation,
value and support to end users, channel partners and OEMs. In addition, the
combination will strengthen Quantum's financial position, expand its market
access and increase its opportunities for growth.



The transaction is expected to be up to 15 cents accretive to Quantum on a cash
earnings per share basis, with annual cost synergies of approximately $45
million in the first full year of combined operations. The company expects that
this accretion should start to be reflected in its financial results within the
second full quarter following the close of the transaction. Based on the
complementary nature of the two companies' businesses, savings are expected to
come primarily from economies of scale and manufacturing efficiencies in cost of
goods sold, reduction of duplicative operating expenses and sharing of R&D
and marketing costs. Given Quantum's previous success in integrating Benchmark
and Certance after those acquisitions, the company expects a smooth and
expeditious integration of ADIC.



"We are very excited about bringing Quantum and ADIC together to create
what will clearly be the largest independent provider of backup, recovery and
archive solutions and a global leader in addressing customers' evolving data
protection challenges," said Rick Belluzzo, Chairman and CEO of Quantum,
who will hold the same position in the combined company. "With an
unparalleled portfolio of systems, software, devices and media, we will be able
to integrate these assets and incorporate value-add features to offer
best-of-breed solutions for customers of all sizes. Our enhanced financial
strength will also enable us to increase our investments in new products and
services both within and beyond our core business."



"Joining with Quantum will deliver tremendous value to both our
shareholders and customers," said Peter van Oppen, Chairman and CEO of ADIC.
"The combined company will provide a single source of intelligent and
innovative backup, recovery and archive solutions that enable end users to
reduce costs and more easily protect and manage their business-critical data.
The combination will also create a stronger go-to-market infrastructure, with
larger and better leveraged sales and service capabilities through which we can
offer greater support to customers."
