Separation Agreement between the Company and Stephen C. Hooley, dated as of February 26, 2018

February 26, 2018

Dear Stephen:

This letter agreement (this “Agreement”) is intended to set forth our mutual understanding and agreement regarding your termination of employment and your right to receive severance amounts under your employment agreement with DST Systems, Inc. (“DST”), dated as of June 30, 2009 (the “Employment Agreement”) and equity award acceleration of your outstanding equity awards in connection with the closing of the transactions contemplated by the Agreement and Plan of Merger (as it may be amended from time to time), dated as of January 11, 2018 (the “Merger Agreement”) by and among DST, SS&C Technologies Holdings, Inc. (“SS&C”) and Diamond Merger Sub Inc. (the “Closing”). From the date hereof through the date of the Closing (the “Closing Date”), you agree to continue to faithfully perform your duties under the Employment Agreement to the best of your ability and shall devote substantially all of your working time and efforts to the business and affairs of DST and its affiliates. You shall continue to comply with any restrictive covenant obligations to DST and its affiliates by which you are bound (including, without limitation, under Sections 5 and 8 of the Employment Agreement).

1.Good Reason. DST and SS&C hereby agree that on the Closing Date your employment with DST shall terminate by mutual agreement immediately upon the Closing for “good reason” under Section 7(e) of your Employment Agreement without any requirement for you to provide written notice or any right of DST or SS&C to remedy the event constituting good reason. You shall also resign by mutual agreement as a member of the Board of Directors of DST (and from any other positions with DST, and as a director and/or officer of any DST affiliate), effective immediately upon the Closing. You agree to execute and deliver any additional notices or other documents reasonably necessary to implement such resignations. In addition, you agree that on and after the Closing Date, you shall not represent yourself as being an employee, officer, director, agent or representative of DST or SS&C or their respective affiliates for any purpose.

2.    Payment Obligations Upon Termination.

(a)    Base Salary. Immediately prior to the Closing, DST shall pay you a lump sum cash amount equal to your accrued and unpaid base salary through the Closing Date, plus a pro rata annual incentive for 2018 in respect of the period through the Closing Date (which such amount shall be determined pursuant to Section 6.09(f) of the Merger Agreement).

(b)    Severance Payment. Immediately prior to the Closing, in satisfaction of its severance obligations under the Employment Agreement, DST shall provide you with a lump sum cash severance payment equal to three times your base salary as in effect on the date hereof and 2018 annual incentive bonus at Target level in the amount of $6,375,000.

(c)    Continued Benefits/Perquisites. Following the Closing, DST and SS&C shall provide you with the Specified Benefits (consisting of life, disability and health insurance premiums and estimated 401(k) plan profit sharing contributions) as provided in Section 7(e) of the Employment Agreement, as set forth in the “Golden Parachutes Compensation” table in the Definitive Proxy Statement for the transactions contemplated by the Merger Agreement. For the avoidance of doubt, such Specified Benefits shall not include the value of any annual equity awards, and you hereby waive any claim to additional severance payments based upon anticipated future equity awards or your prior equity awards.

(d)    Outstanding Equity Awards. All of your outstanding unvested DST equity awards, consisting of RSUs and PSUs, shall fully vest (at the levels specified in the Merger Agreement for PSUs) immediately upon Closing. In lieu of delivery of stock or a conversion of any of your outstanding unvested DST equity awards into SS&C equity awards, the DST Compensation Committee shall authorize, and SS&C agrees, that your outstanding DST equity awards shall be converted into an aggregate cash amount of $20,959,899 (based upon a cash price of $84.00 per share) immediately prior to Closing and, to the extent compliant with Section 409A of the Internal Revenue Code of 1986 and the regulations promulgated thereunder (“Section 409A”), paid to you in a cash lump sum on the Closing Date. In the event that the payment of all or a portion of such cash amount on the Closing Date would not be compliant with Section 409A, then such portion of the cash amount shall be paid out to you (or your estate, in the event of your death) upon the 6^th month and one day anniversary of the Closing Date (or as soon as practicable following your death, if earlier). Both DST and SS&C respectfully acknowledge and agree that, as of the date hereof, each such party is not aware of any fact, event or circumstance that would give rise to a claim against the amount payable to you under this paragraph 2(d) such that SS&C would have a right of offset against, or other right of non-payment with respect to, such amount following the Closing.

(e)    Unreimbursed Business Expenses. Any unreimbursed business expenses incurred by you through the Closing shall be payable to you in accordance with DST’s expense reimbursement policy in effect at the time of Closing.

(f)    Other Accrued Benefits. Any other earned and vested amounts, entitlement or benefits (including 401(k), accrued but unused PTO, 2018 Perquisite Plan benefits (pro-rated through the Closing Date), health insurance claims incurred prior to Closing, and the ability to elect continued health coverage under COBRA, and conversion of group insurance policies to personal policies), to the extent not otherwise described herein, shall be provided to you in accordance with the terms of the applicable

plans and arrangements of DST. You shall continue to be covered under any applicable DST indemnification agreements or policies and under any applicable directors’ and officers’ insurance policies pursuant to the terms of such agreements or policies and the Merger Agreement.

3.    General Provisions.

(a)    Modification or Waiver; Entire Agreement. No provision of this Agreement may be modified or waived except in a document signed by you, DST and SS&C.
