Interest in Securities of the Issuer.

Item 4 of the Schedule 13D is hereby amended to add the following: The information set forth in Item 6 below is incorporated by reference in its entirety into this Item 4.

ITEM 6.

Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

As previously reported, on June 18, 2018, Rimini Street, Inc. (the “Company”) entered into a Securities Purchase Agreement with several affiliates of Adams Street Partners, LLC and other accredited investors for a private placement of the Company’s securities. Pursuant to the Securities Purchase Agreement, the completion of the transaction was conditioned on the satisfaction or waiver of certain conditions, including, among others, that the Company obtain the approval of its stockholders of the issuance of all of the shares to be sold in the financing.

On July 12, 2018, the Company convened a special meeting of stockholders to vote to approve the financing, among other matters. As reported in the Company’s Form 8-K filed with the SEC on July 12, 2018, the stockholders voted to approve the financing transaction at the special meeting.

On July 19, 2018, with all the closing conditions of the Securities Purchase Agreement having been satisfied, the financing transaction closed and affiliates of Adams Street Partners, LLC purchased an aggregate of 397,428 shares of the Company’s common stock and 19,209 shares of the Company’s Series A Redeemable Convertible Preferred Stock for an aggregate purchase price of $18,248,550. As a result of closing the transactions contemplated in the Securities Purchase Agreement, the voting agreements to which certain of the Company’s stockholders, including the reporting person, were parties, as previously described in Amendment No. 2, automatically terminated with no continuing obligations or liabilities upon the parties thereto.
