                      DAVE DORMAN LETTER TO AT&T EMPLOYEES
                                     4/21/05

To the People of AT&T:

This morning, we announced AT&T's first-quarter 2005 earnings results. While you
can read the full details in our press release, I'd like to take a moment to
offer some highlights of the quarter, and to also thank you for all the hard
work that made these results possible.

Because of your efforts, AT&T continues to make solid progress in transforming
our company for long-term networking and technology leadership, in advance of
our pending merger with SBC Communications.

We're successfully reducing costs, improving our capital structure and winning
in the marketplace. And based on our performance in 2004, we continue to outpace
our closest peers on such key metrics as revenue generation, cash flow, employee
productivity and capital investment.

Through AT&T Business, we've transformed AT&T into an enterprise-focused, global
networking and technology leader -- and we continue to expand our product
portfolio to strengthen our best-in-class capabilities for customers. During the
2005 first quarter, we generated $5.3 billion of AT&T Business revenue and a
solid $1.2 billion of EBITDA, for a margin of 22.3 percent. We also continued to
drive strong contract win rates, particularly in the government sector and at
the high end of the enterprise market.

Within ACS, we're executing a "financially optimized" exit from the traditional
residential services market, and our results in the quarter reflect that
discipline. Our ability to quickly ratchet back sales, marketing and related
customer care expenses contributed to first-quarter operating income of $575
million, and a 34.1 percent operating margin.

These are solid results, though I know the road hasn't been easy. And we
shouldn't lose sight of the fact that we continue to operate in a tough industry
and a very challenging pricing environment. For example, AT&T Business revenue
was down by roughly $550 million year-over-year, largely due to significant
pricing pressure in traditional voice and data services. To maintain margins in
that kind of environment, we've had to deliver considerable increases in
productivity. Unfortunately, that's meant ongoing headcount reductions. These
decisions are not easy, but they're also not optional: To remain financially
strong and competitive in the marketplace, we must remain focused on increasing
efficiency and reducing costs.

Despite the challenges, the prospects for the future for the combined AT&T-SBC
are bright. Emerging from the turmoil that's rocked the telecom sector for the
past few years, we now have an opportunity to reshape the industry in a positive
direction. Our success in transforming AT&T's business model -- and the
underlying strength of our global IP network, product suite and customer base --
all played a key role in SBC's 


decision to join forces with us to create a "communications company for the 21st
century." Together, we'll continue to make significant investments in the future
of networking and communications, offering a broad range of applications and
services for businesses and consumers alike.

I understand, however, that the merger also brings uncertainty and anxiety.
While I wish we could tell you today how the combined companies will be
integrated or structured, we simply don't have those answers yet. But I can tell
you a few things. First, the vast majority of our jobs will not be impacted.
Many of our assets and capabilities are unduplicated within SBC, and SBC values
the talent we have at AT&T. On the other hand, it would be naive to say that
there won't be places where there will be duplication or opportunities for
efficiencies across the two companies. But where reductions are necessary, SBC
has said it expects to phase in reductions over a period of time. They will also
attempt to use normal attrition - which averages at least 1,000 people at SBC
every month - to meet reductions wherever possible. Second, this merger will
give each of our companies more opportunities for the future. Together, we hope
to grow this business. And ultimately that means growing personal and
professional opportunities for employees, too.

We'll communicate more as we know more. In the meantime, as we prepare for this
business combination, let's remain focused on meeting customer needs and further
elevating AT&T's overall operational and financial strength. The best thing we
can do is to keep making our company stronger and more competitive every day.

Thanks again for your terrific efforts in the first quarter, your patience
during this time of uncertainty, and your dedication to AT&T. I'm proud of what
we've accomplished together and optimistic about the opportunities ahead.

Dave Dorman
