Explanation of Responses:

1. All share and price amounts reflect two-for-one stock splits effected on June 25, 2001 and June 27, 2005.

2. On August 16, 2001, NYLIFE LLC ("NYLIFE") entered into a SAILS Mandatorily Exchangeable Securities Contract (the "August Contract") with Credit Suisse First Boston International ("CSFBI") and Credit Suisse First Boston Corporation, as agent, relating to the disposition by NYLIFE of up to 9,000,000 shares of common stock of Express Scripts, Inc. ("Common Stock") held by NYLIFE. Specifically, the August Contract obligates NYLIFE to deliver to CSFBI on August 22, 2011 (subject to extension and acceleration) a number of shares of Common Stock equal to the product of the Exchange Rate times 9,000,000 shares, or at NYLIFE's option in lieu of shares, to deliver an amount of cash equal to the Maturity Price (as defined in the August Contract) of the number of shares otherwise deliverable.

3. The Exchange Rate is equal to: (a) if the Maturity Price is less than or equal to $35.135 (the "Threshold Price") but greater than $27.025 (the "Issue Price"), a fraction equal to the Issue Price divided by the Maturity Price; (b) if the Maturity Price is greater than the Threshold Price, a fraction equal to the Issue Price divided by the Threshold Price; and (c) if the Maturity Price is equal to or less than the Issue Price, 1.0, subject in each case to anti-dilution and extraordinary transaction adjustments. NYLIFE received from CSFBI $238,968,562.50 in cash on August 22, 2001, pursuant to the August Contract, representing the Purchase Price under the August Contract, net of certain expenses and fees.

Specifically, the 2003 Contract obligates New York Life Insurance Company to deliver to CSFBI on April 28, 2008 (subject to extension and acceleration) a number of shares of Common Stock equal to the product of the 2003 Exchange Rate times 11,000,000 shares, or at New York Life Insurance Company's option in lieu of shares, 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.

5. The 2003 Exchange Rate is equal to: (a) if the 2003 Maturity Price is less than or equal to $33.258 (the "2003 Threshold Price") but greater than $27.715(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 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 Insurance Company 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.
