This Amendment is being filed by Ilse F. Cooper, an Individual, together with Mathew and Markson (together, the "Reporting Persons"), with respect to their beneficial ownership of the common stock (the "Common Stock" or the "Shares"), Par Value $0.001 per share, of YP Corp., a Nevada corporation, formerly known as RIGL Corporation (the "Issuer"). ITEM 1. SECURITY AND ISSUER This Amendment relates to the Shares of the Issuer, which has its principal offices at 4840 East Jasmine Street, Suite 105, Mesa, Arizona. ITEM 2. IDENTITY AND BACKGROUND (a) This Amendment is being filed by Mathew and Markson. Mathew and Markson was formed for the purpose of acquiring and managing assets. This Amendment is also being filed by Ilse F. Cooper for Mathew and Markson and on behalf of herself as well. Since Ms. Cooper serves as the Managing Director of Mathew and Markson, she may be deemed to control, directly or indirectly, Mathew and Markson and to beneficially own the shares of Common Stock being reported on this Amendment by Mathew and Markson. Ms. Cooper is also the Managing Director of Morris & Miller, Ltd., another corporation which is a Direct Owner of shares of the Common Stock of the Issuer. However, Ms. Cooper, for Mathew and Markson and for Morris & Miller, Ltd. and on behalf of herself as well, hereby declares that the filing of the Original Statement and this Amendment shall not be construed as an admission that Morris & Miller, Ltd. is a beneficial owner of the shares of Common Stock of the Issuer covered by the Original Statement and this Amendment, or that Mathew and Markson is a beneficial owner of the shares of Common Stock of the Issuer covered by any Statements and Amendments which may be filed by Morris & Miller, Ltd. on Schedule 13D.

In October 19, 2006, Mathew and Markson sold 2,000,000 shares of the Issuer's Common Stock. Therefore, this Amendment No. 11 is being filed to indicate that as of October 19, 2006, the total number of Shares of Common Stock of the Issuer held by Mathew and Markson was as follows: Prior Balance 4,060,062 Shares (Disposition) (2,000,000 Shares) New Balance 2,060,062 Shares 5 ITEM 4. PURPOSE OF TRANSACTION The Shares were originally acquired by the Reporting Persons for investment purposes. The Reporting Persons acquired the Shares in order to obtain a substantial equity position in the Issuer based on the Reporting Persons' belief that the Common Stock represented an attractive investment opportunity. The purpose of the transaction was to sell 2,000,000 Shares. Depending upon overall market conditions, or other investment opportunities available to the Reporting Persons in the Issuer, or through the availability of additional Shares at attractive prices, the Reporting Persons may endeavor to increase their position in the Issuer through, among other things, the purchase of shares of Common Stock on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable. The Reporting Persons anticipate that, from time to time, they may communicate with the Issuer regarding the composition of Management and the Issuer's business and strategic opportunities, and they may identify to the Issuer such strategic opportunities and alternatives to be considered by the Issuer. Other than as set forth in this Amendment, neither of the Reporting Persons has any plans or proposal that relate to or would result in any of the results specified in Paragraphs (a) through (j) of ITEM 4 of this Amendment. However, on or about October 17, 2005, the Reporting Persons filed a Shareholder's Proposal seeking a change in control. On or about January 10, 2006, this proposal was withdrawn. ITEM 5.
