BELGRADE, Mont., May 31, 2011 /PRNewswire/ -- Bacterin International Holdings, Inc. ("Bacterin") (NYSE Amex: BONE), a creator and developer of revolutionary bone graft material and anti-infective coatings for medical applications, today announced that it has entered into an equity purchase agreement with Lincoln Park Capital Fund, LLC ("LPC"), a Chicago based asset management firm.  Under the terms of the agreement, Bacterin received an initial investment of $1 million through the sale of shares of its common stock to LPC at $3.06 per share, a price per share equal to the closing price on May 26th, 2011, together with warrants to purchase an additional 130,719 shares at the same price per share, subject to NYSE Amex approval.  These terms are consistent with the Company's previously announced equity capital raise of up to $3.5 million, of which $1,874,502 was raised prior to LPC's investment.  With LPC's investment and an additional $153,000 that was recently raised from outside third parties, subject to NYSE Amex approval, a total of approximately $3,027,504 has been raised at a valuation consistent with the market price of the stock.

In addition, LPC has committed to invest, up to an additional $30 million through the purchase of shares of Bacterin's common stock from time to time over the next three years.  The transactions will be at Bacterin's sole option with no additional warrants granted.

During the 36-month term of the agreement, Bacterin has the right to sell to LPC up to an additional $30 million of its common stock, subject to certain conditions, which include the effectiveness of a registration statement with the U.S. Securities and Exchange Commission covering the sale of the shares that may be issued to LPC. There are no upper limits to the price LPC may pay to purchase Bacterin common stock and the purchase price of the shares related to any future investments will be based on the prevailing market prices of Bacterin's common shares immediately preceding the notice of sale to LPC without any fixed discount.  The Company controls the timing and amount of any future investment and LPC is obligated to make purchases, if and when the Company decides, in accordance with the purchase agreement.  There are no penalties or liquidated damages in the purchase agreement. The agreement may be terminated by the Company at any time, at its sole discretion, without any cost or penalty.
