¹Potter Acquisition Corporation was incorporated on April 7, 2006 as a wholly-owned subsidiary of Oracle Systems Corporation solely for the purpose of consummating a business combination with Portal Software, Inc. and has no operations.

This Amendment No. 8 to the Tender Offer Statement on Schedule TO (this “Amendment”), filed with the Securities and Exchange Commission (the “SEC”) on July 3, 2006, amends and supplements the Tender Offer Statement on Schedule TO filed on April 25, 2006, as amended (the “Schedule TO”), and relates to the offer by Potter Acquisition Corporation, a Delaware corporation (“Offeror”) and a wholly-owned subsidiary of Oracle Systems Corporation, a Delaware corporation (“Parent”), which is a wholly-owned subsidiary of Oracle Corporation, a Delaware corporation (“Oracle”), to purchase all outstanding shares of Common Stock, par value $0.001 per share, and the associated preferred stock purchase rights (together, the “Shares”) of Portal Software, Inc., a Delaware corporation (the “Company”), for $4.90 per Share, net to the seller in cash without interest thereon, less any required withholding taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated April 25, 2006, as amended (the “Offer to Purchase”), and the related Letter of Transmittal (which, together with the Offer to Purchase, and any amendments or supplements thereto, collectively constitute the “Offer”). Capitalized terms used and not defined herein shall have the meanings assigned such terms in the Offer to Purchase.

The Offer is made pursuant to the Agreement and Plan of Merger, dated as of April 11, 2006, as amended (the “Merger Agreement”), among Offeror, Parent and the Company.

The information in the Offer to Purchase and the related Letter of Transmittal is incorporated in this Amendment by reference to all of the applicable items in the Schedule TO, except that such information is hereby amended and supplemented to the extent specifically provided herein.

Item 8. Interest in Portal Securities.

Item 8 of the Schedule TO is hereby amended and supplemented by including the following:

“The subsequent offering period of the Offer expired at 8:00 pm, New York City time, on June 30, 2006. In the Offer, an aggregate of approximately 38.3 million Shares were validly tendered and not withdrawn, representing approximately 88.6 percent of the outstanding Shares. Offeror has accepted for payment all tendered Shares. Together with the approximately 5.3 million Shares acquired by Oracle, Parent, and Offeror through open market purchases at $4.90 per Share and through the exercise of the irrevocable option to purchase that number of Shares equal to the lowest number of Shares that, when added to the number of Shares owned by Offeror at the time of such exercise, would constitute one share more than 90% of the Shares then outstanding (as described more fully in the Offer to Purchase), Oracle, Parent and Offeror collectively control 90 percent of the outstanding Shares.”

Item 11. Additional Information.

Item 11 of the Schedule TO is hereby amended and supplemented by including the following:

“On July 3, 2006, Oracle announced the expiration of the subsequent offering period at 8:00 pm, New York City time, on June 30, 2006. In the Offer, an aggregate of approximately 38.3 million Shares were validly tendered and not withdrawn, representing approximately 88.6 percent of the outstanding Shares. Offeror has accepted for payment all tendered Shares. Together with the approximately 5.3 million Shares acquired by Oracle, Parent, and Offeror through open market purchases at $4.90 per Share and through the exercise of the irrevocable option to purchase that number of Shares equal to the lowest number of Shares that, when added to the number of Shares owned by Offeror at the time of such exercise, would constitute one share more than 90% of the Shares then outstanding (as described more fully in the Offer to Purchase), Oracle, Parent and Offeror collectively control 90 percent of the outstanding Shares.

On July 3, 2006, Oracle also announced that the second step merger of Offeror with and into the Company (the “Merger”) occurred on July 3, 2006. In connection with the Merger, each outstanding Share not tendered in the Offer (other than Shares held by the Company, Oracle, Parent and Offeror and Shares held by stockholders who properly perfect appraisal rights under Delaware law) was converted into the right to receive $4.90 per share in cash, without interest. Following the consummation of the Merger, the Company will continue as the surviving corporation and be a wholly-owned subsidiary of Parent.”
