On November 25, 2009, DST Systems, Inc. (the "Company") announced that the Company entered into separate privately negotiated exchange agreements under which it exchanged $66.6 million in aggregate principal of the Company’s outstanding 4.125% Series A Convertible Senior Debentures due 2023 (“Existing Debentures”) for $66.6 million in aggregate principal of new 4.125% Series C Convertible Senior Debentures due 2023 ("New Debentures").

The New Debentures were issued under an indenture between the Company and the Bank of New York Mellon Trust Company, N.A., as trustee, as supplemented by Supplemental Indenture No. 1 (together, the "New Debentures Indenture").

The Company offered the New Debentures to the holders of the Existing Debentures in reliance on the exemption from registration provided by Section 4(2) of the Securities Act of 1933. Shares of the Company’s common stock, into which the New Debentures are convertible, have been reserved for issuance by the Company and will be listed on the New York Stock Exchange.

The New Debentures will bear regular cash interest on the original principal amount of each debenture at a rate of 4.125% per year on the New Debentures, payable semiannually in arrears on February 15, 2010. Beginning on August 15, 2010, the Company will not pay regular cash interest on the debentures prior to maturity. Instead, the original principal amount of each debenture will increase at a rate of 4.125% per year, computed from August 15, 2010, on a semiannual bond equivalent basis using a 360-day year composed of twelve 30-day months. On the maturity date of the debentures, a holder will receive, for each $1,000 original principal amount of debentures, $1,700.28 for the New Debentures.

Beginning on August 20, 2010, the Company will pay additional contingent interest on the New Debentures if the average trading price of the New Debentures is above a specified level during a specified period. For the period from August 20, 2010 to February 14, 2011, and thereafter for any six-month interest period from February 15 to August 14 or August 15 to February 14, the Company will pay contingent interest for such period if the average trading price of the New Debentures for the applicable five trading-day reference period equals or exceeds 120% of the accreted principal amount of the New Debentures. The Company will pay contingent interest on the interest payment date immediately following the applicable six-month interest period. The amount of contingent interest payable per New Debenture in respect of any six-month interest period will be equal to 0.19% of the average trading price of a New Debenture for the applicable five trading-day reference period. The "five trading-day reference period" means the five trading days ending on the second trading day immediately preceding the relevant six-month interest period.

The New Debentures are convertible under certain circumstances by holders into shares of our common stock per $1,000 original principal amount of debentures at an initial conversion rate of 20.3732 shares (subject to adjustment in certain events). This is equivalent to an initial conversion price of $49.08 per share for the New Debentures. The New Debentures are convertible under any of the following circumstances: (1) the closing price of the Company's

common stock reaches a specified threshold, (2) the trading price per New Debenture falls below a specified threshold, (3) if the Company calls the New Debentures for redemption or (4) upon the occurrence of specified corporate transactions, each as described in the New Debentures Indenture. Upon conversion, the Company will have the right to deliver, in lieu of common stock, cash or any combination of cash and common stock. The New Debentures include a make-whole interest provision which may increase the conversion rate upon certain fundamental changes, as described in the New Debentures Indenture, prior to August 15, 2013.

Holders may convert their New Debentures into shares of the Company's common stock under any of the following circumstances:

The New Debentures will mature on August 15, 2023. The Company may redeem some or all of the New Debentures at any time on or after August 15, 2013 in cash at the redemption price described below. As described above, Holders will have the right to convert their New Debentures if the New Debentures have been called for redemption, and upon conversion, the Company will have the right to deliver, in lieu of common stock, cash or any combination of cash and common stock. Holders will have the right to require the Company to purchase the New Debentures at the purchase price described below on August 15, 2014, August 15, 2015 and August 15, 2020, or upon a fundamental change, as described in the New Debentures Indenture. For purchases on August 15, 2014, the Company will pay the purchase price in cash. Thereafter, and upon any fundamental change, the Company can pay the purchase price at its option in cash, common stock or any combination of cash and common stock. The redemption or purchase price shall be a price equal to the accreted principal amount of the New Debentures to be redeemed or purchased plus any accrued and unpaid cash interest, including contingent interest, if any, to the redemption or purchase date.

The New Debentures are unsecured and rank equally with all of the Company's other existing and future unsecured and unsubordinated indebtedness.

The foregoing description of the New Debentures Indenture and the New Debentures is qualified in its entirety by reference to the New Debentures Indenture and the form of the New Debenture. A form of the New Debentures Indenture was previously filed as Exhibit 4.1 to the Company's Form 8-K filed on October 1, 2009. The Supplemental Indenture No.1 to Indenture is filed herewith as Exhibit 4.1, and the Form of the Series C Convertible Senior Debenture is filed herewith as Exhibit 4.2.
