Item 1.01. Entry into a Material Definitive Agreement.

Saba Software, Inc. (the “Company”) entered into an amendment, dated as of May 31, 2013 (the “Amendment”), to that certain Amended and Restated Credit Agreement, dated as of June 27, 2011 (the “Original Credit Agreement” and, as amended by the Amendment, the “Credit Agreement”), with Wells Fargo Bank, National Association (“Wells Fargo”) and certain wholly-owned subsidiaries of the Company.

Under the Original Credit Agreement, the Company was not able to access additional advances under the revolving line of credit due primarily to defaults relating to the Company’s restatement of prior period financial statements and certain springing financial covenants. As amended, the Credit Agreement enables the Company to obtain additional advances under the line of credit. At the effective time of the Amendment, there was approximately $14 million of additional availability under the line of credit. Among other things, the Amendment extends the time for the Company to file certain delayed periodic reports with the Securities and Exchange Commission until September 30, 2013, and includes revised financial covenants and liquidity requirements.

A copy of the Amendment is attached hereto as Exhibit 10.1 and the foregoing description of the Credit Agreement and Amendment is qualified in its entirety by reference to Exhibit 10.1 and the copy of the Original Credit Agreement previously field by the Company on its Form 8-K dated June 28, 2011.

The information set forth in Item 1.01 above is hereby incorporated into this Item 2.03 by reference.

Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

As previously reported, the Company’s common stock was suspended from trading on the NASDAQ Global Select Market (“NASDAQ”) on April 9, 2013. As expected, NASDAQ announced today that it will file a Form 25 with the Securities and Exchange Commission to complete the delisting. The delisting becomes effective 10 days after the Form 25 is filed.
