International Stem Cell Corporation Announces $25 Million Common Stock Financing Agreement

International Stem Cell Corporation (OTCBB:ISCO),http://www.internationalstemcell.com, announced today that it had entered into an agreement with Aspire Capital Fund, LLC, to provide, at the Company's sole option, up to $25 million of equity capital over the next three years. As part of this transaction, Aspire purchased, upon execution of the agreement, 333,333 shares of ISCO Common Stock at a price of $1.50 per share, a 7% premium over Friday's closing price of $1.40 per share.

Pricing of future sales under the agreement will be determined each time the Company elects to sell shares to Aspire by a formula that is based on the actual sale prices of the Company's stock over the 12 days preceding each sale to Aspire. Thus, the Company will control the timing and amount of any sales of its Common Stock to Aspire, and will always know at the time it gives a notice of sale what the cost of that round of financing will be.

Aspire has no right to require any sales by the Company, but is obligated to make purchases as the Company directs in accordance with the purchase agreement, and the Company has the right to terminate the agreement at any time. The agreement does not restrict other financings by the Company. A more detailed description of the transaction agreements with Aspire is set forth in the Company's current report on Form 8-K, filed today with the U.S. Securities and Exchange Commission.

Ray Wood, Chief Financial Officer of ISCO, commented on the agreement, "This transaction is designed to provide both a source of working capital and maximum flexibility for the Company in determining the pricing and timing of any future financing it elects to use under this agreement. It provides us with access to capital that we believe will be adequate to fund our research activities for an extended period of time, but does not preclude us from pursuing additional financing during the term of the agreement. Because of the pricing flexibility this facility gives us, we believe that this agreement will provide both the lowest cost of capital currently available, plus maximum flexibility in meeting our future financing needs. If we don't need working capital or don't need as much as expected, we may elect not to use the facility. If we do need capital, it is available and we can choose when to obtain it."
