Item 1. Security and Issuer

This Amendment No. 4 (“Amendment No. 4”) relates to the Schedule 13D filed by Abacus Investments Limited (“Abacus”) with the Securities and Exchange Commission (the “Commission”) on November 22, 2006, as amended by Amendment No. 1, filed on December 22, 2006, Amendment No. 2, filed on November 20, 2007 and Amendment No. 3, filed on December 11, 2007 (as so amended, the “Schedule 13D”), with respect to the common stock, par value $0.001 per share (“Common Stock”), of BMP Sunstone Corporation, a Delaware corporation (the “Company”).

Item 4. Purposes of Transactions

Item 4 is amended and restated as follows:

Abacus has held all the shares of Common Stock beneficially owned by it for the purpose of investment. Abacus evaluates its investment on a continuing basis. On January 25, 2009, Abacus’ board of directors approved (i) a plan of complete liquidation of Abacus, (ii) the appointment of a liquidator to oversee the plan of complete liquidation and (iii) submission of such matters for a vote of the Abacus shareholders. On January 27, 2009, the Abacus shareholders approved each of these matters by majority written consent, and Abacus is proceeding with its plan of complete liquidation, which includes, among other things, an in kind pro rata distribution of the shares of Common Stock currently held by Abacus to its shareholders. Following the completion of the distribution, Abacus will no longer beneficially own any Common Stock. Abacus expects the distribution of shares of Common Stock to be completed in February 2009 and the liquidation to be completed in March 2009.

The preceding information is being disclosed pursuant to Item 4(a) of Schedule 13D. Other than the potential liquidation and distribution described above, Abacus has no plan or proposals with respect to the Issuer that relate to or could result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D. Abacus, however, may at any time and from time to time, review or reconsider its position with respect to any of such matters.

Item 5. Interest in Securities of the Issuer

Item 5(a) is amended and restated as follows:

As of the date hereof, Abacus is the beneficial owner of 7,907,484 shares of Common Stock which constitutes approximately 19.65% of the Company’s 40,246,410 issued and outstanding shares of Common Stock, based on information contained in a Form 10-Q filed by the Company with the SEC on November 10, 2008.

John F. Turben, Chairman and Chief Executive Officer of Abacus, is the owner of 43,478 shares of common stock. With the exception of Mr. Turben’s ownership, no executive officer or director owns any shares of Common Stock except for his or her indirect ownership of the Common Stock owned by Abacus.
