Item 1.01. Entry into Material Definitive Agreement

On May 23, 2012, SS&C Technologies Holdings, Inc., a Delaware corporation (“SS&C Holdings”), entered into a First Amendment to Credit Agreement (the “Amendment”), amending the Credit Agreement, dated as of March 14, 2012 (the “Credit Agreement”), among SS&C Technologies, Inc., a Delaware corporation and wholly owned subsidiary of SS&C Holdings (“SS&C Technologies”), SS&C Technologies Holdings Europe S.A.R.L., a Luxembourg société à responsabilité limitée and an indirect wholly-owned subsidiary of SS&C Holdings, as the borrowers, SS&C Holdings, certain subsidiaries of SS&C Technologies as guarantors, Deutsche Bank AG New York Branch, as administrative agent, swing line lender and letter of credit issuer, the other lenders party thereto and Deutsche Bank Securities, Inc., Barclays Bank PLC, Credit Suisse Securities (USA) LLC and Wells Fargo Securities, LLC, as joint lead arrangers and joint bookrunners. Capitalized terms used but not otherwise defined herein shall have the meanings given to such terms in the Amendment.

The Amendment modified certain provisions of the Credit Agreement, including (i) increasing the aggregate amount of Term A-2 Commitments by $25,000,000, with a corresponding $25,000,000 reduction in the Term B-2 Commitments; and (ii) increasing the applicable interest rate margin for Term B-1 and Term B-2 Loans by 0.75% per annum. Certain of the modifications to the Credit Agreement effectuated by the Amendment resulted from the exercise of market flex rights by the joint lead arrangers in connection with the syndication process.

The foregoing description of the Amendment does not purport to be a complete statement of the parties’ rights under such agreement and is qualified in its entirety by reference to the full text of the Amendment, which is attached hereto as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

In the ordinary course of business, the joint lead arrangers and their affiliates have engaged, and may in the future engage, in commercial banking and/or investment banking transactions with SS&C Holdings, SS&C Technologies and their affiliates for which the joint lead arrangers and their affiliates have in the past received, and may in the future receive, customary fees.
