On December 27, 2004, Gartner, Inc. sent the following letter to its clients.

To Our Valued Clients:

I am delighted to share with you the news that Gartner, Inc. has reached an
agreement to acquire META Group. Upon completion of the transaction, the
combined company's professional staff of research analysts and consultants will
be able to provide an even greater scope of independent, objective counsel to
help senior IT and business executives leverage information technology to meet
their strategic objectives.

META Group represents an outstanding strategic fit with Gartner. The acquisition
of META Group allows us to expand our ability to deliver the broadest, deepest,
most timely advice and consulting on information technology.

We expect the transaction, which is subject to customary closing conditions,
including regulatory approvals, and approval by META Group's stockholders, to
close in the second quarter 2005. We will keep you informed of developments as
they occur. As Gartner moves forward, I want to thank you for allowing us to be
your partner. We look forward to continuing and growing our relationship with
you in the future.

Most Sincerely,
