<p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"><font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2">The carrying amounts of cash and cash equivalents, available-for-sale securities, prepaid expenses, accounts receivable, accounts payable and accrued expenses and other short-term assets and liabilities approximate fair value due to the short-term nature of these instruments. The derivative liability is also carried at fair value.</font></p>
<p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"> </p>
<p style="TEXT-INDENT: 0.5in; MARGIN: 0in 0in 0pt;"><font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2">Fair value is an exit price, representing the amount that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is determined based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect certain market assumptions. As a basis for considering such assumptions, GAAP establishes a three-tier value hierarchy, which prioritizes the inputs used to develop the assumptions and for measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets for identical assets; (Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions. This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value.</font></p>
