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. 7 to the Tender Offer Statement on Schedule TO (this “Amendment”), filed with the Securities and Exchange Commission (the “SEC”) on June 21, 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.

Items 4 and 8. Terms of the Offer; Interest in Securities of the Company

Items 4 and 8 of the Schedule TO are hereby amended and supplemented by including the following:

The initial offering period of the Offer expired at 12:00 midnight, New York City time, on Tuesday, June 20, 2006. According to Computershare Trust Company, N.A., the depositary for the Offer, approximately 32.0 million Shares (including Shares tendered by notice of guaranteed delivery) were validly tendered and not withdrawn as of the expiration date of the initial offering period of the Offer, representing approximately 74% of the outstanding Shares. The Offeror has accepted for payment all tendered shares.

On June 21, 2006, Parent and Offeror announced a subsequent offering period commencing on Wednesday, June 21, 2006 and expiring on Friday, June 30, 2006 at 8 p.m., New York City time. During the subsequent offering period, the Offeror will accept for payment and promptly pay for Shares as they are tendered. Stockholders who tender Shares during such period will be paid the same $4.90 per share cash consideration paid during the initial offering period. Shares tendered during the subsequent offering period may not be withdrawn. The Offeror may extend the subsequent offering period. If the subsequent offering period is extended, the Offeror will notify the depositary for the Offer and issue a press release prior to 9:00 a.m., New York City time, on the first business day following the date the subsequent offering period was scheduled to expire.

Pursuant to the terms and conditions of the Merger Agreement, Offeror will be merged with and into the Company (the “Merger”) as soon as practicable after the expiration of the subsequent offering period (as it may be extended). If Offeror acquires at least 90% of the outstanding Shares as a result of the subsequent offering period or otherwise, the Merger will occur promptly thereafter. Otherwise, the Merger will occur promptly after the Merger Agreement is approved and adopted by the holders of a majority of the outstanding Shares (including Offeror) at a special meeting of the Company’s stockholders. 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) will be 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.

The press release announcing the expiration of the initial offering period and the commencement of the subsequent offering period is attached hereto as Exhibit (a)(5)(v).

Item 12. Exhibits

Item 12 of the Schedule TO is hereby amended and supplemented by adding the following exhibit:
