On October 31, 2018, BlackLine Systems, Inc. (the “Company”), a wholly-owned subsidiary of BlackLine, Inc. (“BlackLine”), entered into an Amendment (the “Amendment”) to the Software Development Cooperation Agreement (the “SAP Agreement”), dated October 1, 2013, with SAP SE (as successor to SAP AG) (“SAP”). BlackLine has a strategic relationship with SAP to market its solution to users of SAP’s ERP solutions. As part of this strategic relationship, the Company agreed under the terms of the SAP Agreement to pay SAP a fee based on a percentage of revenues from the Company’s new customers that use an SAP ERP system over the term of their subscription agreements (the “License Royalties”).

Under the terms of the Amendment, effective October 1, 2018, the Company will no longer be obligated to pay the License Royalties to SAP. The BlackLine solution will continue to be an SAP-endorsed business solution.

The foregoing summary is not complete and is qualified in its entirety by reference to the Amendment, which will be filed as an exhibit to the Company’s Annual Report on Form 10-K for the fiscal year ending December 31, 2018.
