                  b. Percent of class: 5.7% based on 78,543,451 shares
                     outstanding as reported in the Quarterly Report on

                  c. Number of shares as to which such person has:

                     i.   Sole power to vote or to direct the vote:  0

                     ii.  Shared power to vote or to direct the vote: 4,500,000

                  *Does not include an aggregate of 29,311 shares held or
managed by investment management subsidiaries of New York Life in an investment
management or fiduciary capacity.

                  NYLIFE is the beneficial owner of 4,500,000 shares (the
"NYLIFE Shares") of Common Stock, which represents approximately 5.7% of the
outstanding shares of Common Stock based on 78,543,451 shares outstanding as
reported in the Quarterly Report on Form 10-Q filed by the Issuer with the
Securities and Exchange Commission on October 30, 2003. New York Life owns the
entire limited liability company interest of NYLIFE and, as a result, may be
deemed to be the beneficial owner of the NYLIFE Shares.

                  On November 7, 2000, in connection with an offering of certain
securities issued by the Express Scripts Automatic Exchange Security Trust, a
trust not affiliated with either Reporting Person or Express Scripts, Inc. (the
"Trust"), NYLIFE entered into a forward purchase agreement (the "Contract") with
the Trust relating to the disposition by NYLIFE of up to 6,900,000 shares of
Common Stock held by NYLIFE (the "Contract Shares"). On February 11, 2002 NYLIFE
effected a distribution to New York Life which included the Contract Shares and
New York Life assumed NYLIFE's obligations under the Contract. On November 17,
2003, New York Life settled its obligations under the Contract with the Trust by
delivering 5,749,770 shares of Common Stock and retaining 1,150,230 shares of
Common Stock.

                  On April 28, 2003, New York Life entered into a SAILS
Mandatorily Exchangeable Securities Contract (the "2003 Contract") with Credit
Suisse First Boston International ("CSFBI") and Credit Suisse First Boston
Corporation, as agent, relating to the disposition by New York Life of up to
5,500,000 shares of Common Stock held by New York Life (the "2003 Contract
Shares"). Specifically, the 2003 Contract obligates New York Life to deliver to
CSFBI on April 28, 2008 (subject to extension and acceleration) (the "2003
Maturity Date") a number of shares of Common Stock equal to the product of the
2003 Exchange Rate (as defined below) times 5,500,000, or at New York Life's
option, to deliver an amount of cash equal to the 2003 Maturity Price (as
defined in the 2003 Contract) of the number of shares otherwise deliverable. The
2003 Exchange Rate is equal to: (a) if the 2003 Maturity Price is less than or
equal to $66.516 (the "2003 Threshold Price") but greater than $55.43 (the "2003
Issue Price"), a fraction equal to the 2003 Issue Price divided by the 2003
Maturity Price; (b) if the 2003 Maturity Price is greater than the 2003
Threshold Price, a ratio equal to one (1) minus a fraction, the numerator of
which equals the excess of the 2003 Threshold Price over the 2003 Issue Price
and the denominator of which equals the 2003 Maturity Price; and (c) if the 2003


                                Page 6 of 9 Pages





Maturity Price is equal to or less than the 2003 Issue Price, 1.0, subject in
each case to anti-dilution and extraordinary transaction adjustments. New York
Life received from CSFBI $272,549,310 in cash on May 1, 2003, pursuant to the
2003 Contract, representing the Purchase Price under the 2003 Contract, net of
certain expenses and fees.

                  As previously reported, on August 22, 2001 NYLIFE entered into
a SAILS Mandatorily Exchangeable Securities Contract with Credit Suisse First
Boston International relating to the disposition by NYLIFE of up to 4,500,000
shares of Common Stock held by NYLIFE.

                  Under a Stockholder and Registration Rights Agreement between
the Issuer and New York Life, New York Life has agreed, and agreed to cause each
of its subsidiaries, including NYLIFE, to vote all voting securities of the
Issuer held by New York Life and its subsidiaries (excluding shares managed for
unrelated customers by New York Life or its investment management subsidiaries),
in favor of the Issuer's slate of nominees for directors recommended by the
Issuer's Board of Directors for election by stockholders of the Issuer (provided
that, so long as New York Life is entitled to representation on the Issuer's
Board of Directors pursuant to the Stockholder and Registration Rights
Agreement, such slate includes New York Life's nominees).
