Item 1.01 Entry into a Material Definitive Agreement

On June 29, 2012, Mattersight Corporation (the “Company”), together with its wholly-owned subsidiaries Mattersight Europe Holding Corporation and Mattersight International Holding, Inc., as co-borrowers, entered into a Loan and Security Agreement with Silicon Valley Bank (the “Credit Facility”). The Credit Facility provides for a $10,000,000 revolving line of credit maturing in 2014 and is secured by a security interest in the Company’s accounts receivable, equipment, inventory, cash, deposit accounts, securities, and all other investment property, supporting obligations, financial assets, and other personal property, with the exception of the Company’s intellectual property rights. The Company and its subsidiaries, subject to certain limits and restrictions, may from time to time request the issuance of letters of credit under the Credit Facility.

On June 29, 2012, the Company used the Credit Facility to repay in full the principal balance and accrued and unpaid interest outstanding under the promissory notes issued by the Company to various affiliates of Technology Crossover Ventures to settle previously disclosed arbitration, in an amount equal to approximately $3.7 million. The principal amount outstanding under the Credit Facility will accrue interest at a floating annual rate equal to three quarters of one percentage point (0.75%) above the United States prime rate, payable monthly. In addition, the Company will pay a commitment fee on the Credit Facility and a fee equal to one-eighth of one percent (0.125%) per annum of the average unused portion of the Credit Facility, payable quarterly in arrears.

The Credit Facility imposes various restrictions on the Company, including usual and customary limitations on the ability of the Company or any of its subsidiaries to incur debt and to grant liens upon their assets, and prohibits certain consolidations, mergers, and sales and transfers of assets by the Company and its subsidiaries. The Credit Facility includes usual and customary events of default for facilities of this nature (with customary grace periods, as applicable) and provides that, upon the occurrence of an event of default, payment of all amounts payable under the Credit Facility may be accelerated and/or the lenders’ commitments may be terminated. In addition, upon the occurrence of certain insolvency or bankruptcy related events of default, all amounts payable under the Credit Facility will automatically become immediately due and payable, and the lenders’ commitments will automatically terminate.

The description of the Credit Facility contained herein does not purport to be complete and is qualified in its entirety by reference to the full text of the Credit Facility, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

Item 1.02 Termination of a Material Definitive Agreement

Upon the effectiveness of the Credit Facility defined and described in Item 1.01, the Company terminated the loan agreement with Bank of America, N.A., dated December 24, 2010, as amended, which was scheduled to expire by its terms on December 31, 2012.
