Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an
Off-Balance Sheet Arrangement of a Registrant On August 20, 2008, we borrowed $1 million from Rogers Telecommunications Limited pursuant to the terms of an unsecured Promissory Note and Agreement (the "Loan"). Outstanding principal and interest on the Loan, which accrues at the rate of 13.5% per annum, is payable in one balloon payment upon the later of three months or our repayment of our $5.0 million loan from BlueCrest which is scheduled to mature in May 2010. At our election, we may make quarterly interest payments on the Loan in shares of our common stock. In addition, in the event we complete a private placement of our common stock and/or securities exercisable for or convertible into our common stock which generates at least $19 million of gross proceeds, we may prepay, without penalty, all outstanding principal and interest due under the Loan using the same type of securities issued in the subject private placement. The Loan will be used for our ongoing clinical and business operations, as we continue to actively pursue additional capital. If we continue to defer approximately $1.0 million of payables and continue to defer our payment of $3.0 million to Cell Transplants International, we project that our existing cash resources, including the proceeds of the Loan, will be sufficient to finance our operations through September 2008. For a full discussion of our liquidity and cash resources and the risks relating thereto, please refer to the "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Risk Factors" in our Annual Report on Form 10-K, as amended by Amendment No. 1 on Form 10-K/A, for the year ended December 31, 2007 and our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2008 and June 30, 2008.
On August 21, 2008, we issued a press release announcing the matter discussed above. A copy of that press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.
