DILUTION

If you invest in our common stock in this offering, your interest will be diluted immediately to the extent of the difference between the initial offering price per share of our common stock and the pro forma as adjusted net tangible book value per share of our common stock after this offering. Our pro forma net tangible book value as of March 31, 2014 was ($14.4 million), or ($2.12) per share of common stock. Pro forma net tangible book value per share represents the amount of our total tangible assets less our total liabilities, divided by the number of shares of common stock outstanding, as of March 31, 2014, after giving effect to the issuance of 1,684,096 shares of our common stock upon the closing of the acquisitions of the Target Sellers, and 117,078 shares of our common stock upon conversion of the convertible debt we issued in September 2013, which is expected to occur upon the closing of this offering.

After giving effect to the sale by us of 4,080,000 shares of common stock in this offering at the initial public offering price of $5.00 per share, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us, our pro forma as adjusted net tangible book value as of March 31, 2014 would have been $3.4 million, or $0.31 per share. This amount represents an immediate increase in pro forma net tangible book value of $2.43 per share to our existing stockholders and an immediate dilution in pro forma net tangible book value of approximately $4.69 per share to new investors purchasing shares of common stock in this offering at the initial public offering price. The following table illustrates this dilution:

If the underwriters exercise their option to purchase additional shares from us in full, the pro forma as adjusted net tangible book value per share of our common stock immediately after this offering would be $0.29 per share, and the dilution in pro forma net tangible book value per share to new investors in this offering would increase by $0.02 per share. If the underwriters exercise their option to purchase additional shares, the proceeds, net of the underwriting discount, will be paid to the Target Sellers.
