The terms of the Senior Guarantees are contained in the Senior Indenture. The Senior Subordinated Notes and the Senior Subordinated Guarantees have been issued under an indenture dated as of August 11, 2005 (the “Senior Subordinated Indenture” and, together with the Senior Indenture, the “Indentures”) among the Company, Solar, the Guarantors and the Trustee. The terms of the Senior Subordinated Guarantees are contained in the Senior Subordinated Indenture. This opinion is furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

We have examined and relied upon the information set forth in the Registration Statement on Form S-1, as amended (the “Registration Statement”) filed by SunGard and the Guarantors with the Securities and Exchange Commission (the “Commission”) relating to the Registration and
