Executive Committee
-------------------

     The announced PacifiCare merger was discussed with you last week, but I
     will take a moment and revisit the powerful underpinnings of that merger
     once more. This combination offers:

          o    Strong diversification into the vast senior market place for
               which we bring complementary assets and knowledge to serve the
               growing needs of American seniors.

          o    It creates favorable balance toward the Pacific and far west
               markets for commercial product lines.

          o    There is complementary diversification into specialty and
               ancillary service lines, including strong and expanding PBM
               capabilities.

          o    We combine to offer the best assets to address the growing
               consumer-directed health care market.

          o    The merger is immediately accretive in a range of 5 to 6 cents
               without synergies or Part D contributions.

          o    Network, care management and operating synergies exist in a range
               of $275 to $350 million - with $75 million to $100 million
               available by the end of the first twelve months following
               closure.

          o    The combination positions both enterprises to better serve the
               new market needs of seniors participating in the Medicare
               Advantage and Medicare Part D programs in 2006 and beyond.

     We currently hope to obtain all appropriate approvals and close on this
     combination late this year so we can focus on the consumer needs and
     opportunities beginning January 1, 2006.

Forward-Looking Statements
--------------------------

This excerpt may contain statements, estimates or projections that constitute
"forward-looking" statements as defined under U.S. federal securities laws.
Generally the words "believe," "expect," "intend," "estimate," "anticipate,"
"project," "will" and similar expressions identify forward-looking statements,
which generally are not historical in nature. By their nature, forward-looking
statements are subject to risks and uncertainties that could cause actual
results to differ materially from our historical experience and our present
expectations or projections. These risks and uncertainties include, among
others, our ability to consummate the merger with PacifiCare, to achieve
expected synergies and operating efficiencies in the merger within the expected
time-frames or at all and to successfully integrate our operations; such
integration may be more difficult, time-consuming or costly than expected;
revenues following the merger may be lower than expected; operating costs,
customer loss and business disruption, including, without limitation,
difficulties in maintaining relationships with employees, customers, clients or
suppliers, may be greater than expected following the merger; the regulatory
approvals required to complete the merger may not be obtained on the terms
expected or on the anticipated schedule; our ability to meet expectations
regarding the timing, completion and tax treatment of the merger and the value
of the merger consideration; and those risks and uncertainties found in our
filings and reports filed with the Securities and Exchange Commission from time
to time, including our annual reports on Form 10-K, quarterly reports on Form
10-Q and current reports on Form 8-K. You should not place undue reliance on
forward-looking statements, which speak only as of the date they are made.
Except to the extent otherwise required by federal securities laws, we do not
undertake to publicly update or revise any forward-looking statements.
