[1] The aggregate consideration paid at closing for the acquisition of ZenContent consisted of a cash payment of $400,000 and the issuance of 86,207 shares of IZEA common stock valued at $600,000.

[2] Aggregate future consideration consists of (i) three equal annual installment payments totaling $1,000,000, commencing 12 months following the closing, less a reduction of $66,435 due to a customary closing date working capital adjustment (“guaranteed purchase price”), and (ii) contingent performance payments up to an aggregate of $2,500,000 over the three 12-month periods following the closing. These payments are also subject to a downward adjustment up to 30% if Brianna DeMike, ZenContent’s co-founder, is terminated by IZEA for cause or if she terminates her employment without good reason. As a result, the Company initially reduced its acquisition cost liability by $300,000 to be accrued as compensation expense over the three-year term rather than allocated to the initial purchase price in accordance with ASC 805-10-55-25. Compensation expense added to the guaranteed acquisition costs payable and recorded as general and administrative expense in the Company's consolidated statement of operations was $11,458 and $61,458 for the three months ended March 31, 2018 and 2017, respectively. The initial guaranteed purchase price consideration was discounted to present value using the Company's borrowing rate of prime plus 2% (5.5% on July 31, 2016). Interest expense imputed on the guaranteed acquisition costs payable in the accompanying consolidated statement of operations was $5,847 and $8,022 for the three months ended March 31, 2018 and 2017.

[3] The contingent performance payments are subject to ZenContent achieving certain minimum revenue thresholds over 36 months. ZenContent is required to meet minimum revenues of $2.5 million, $3.5 million and $4.5 million in the first, second and third, respective 12-month periods following the closing in order to receive any portion of the contingent performance payments. Of these payments, 33% of each such annual installment or contingent performance payment will be in the form of cash and the remainder of such payment will be in the form of either cash or additional shares of IZEA common stock at then average stock prices (determined at IZEA’s option). Additionally, these payments are subject to downward adjustment of up to 30% if Brianna DeMike is terminated by IZEA for cause or she terminates her employment without good reason. The Company initially determined the fair value of the $2,500,000 contingent payments to be $230,000. The fair value of the contingent performance payments is required to be revalued each quarter and is calculated using a Monte-Carlo simulation to simulate revenue over the future periods. Since the contingent consideration has an option like structure, a risk-neutral framework is considered appropriate for the valuation. The Company started with a risk-adjusted measure of forecasted revenue (using a risk-adjusted discount rate of 17%) and assumed it will follow geometric brownian motion to simulate the revenue at future dates. Once the initial revenue was estimated based off of projections, payout was calculated for each year and present valued to incorporate the credit risk associated with these payments. The Company's fair value conclusion was based on the average payment from 250,000 simulation trials. The volatility used for the simulation was 45%. The interest rate used for the simulation was the Company's current borrowing rate of prime plus 2% (6.75%). The Company revalued its estimate of the contingent performance payment as of March 31, 2018 based on actual results and projections and the rates noted above and determined that current fair value of the contingent performance payments was $339,958 compared to $744,510 as of December 31, 2017. The change in the estimated fair value of contingent performance payable resulted in a $404,552 decrease in general and administrative expense in the Company's consolidated statement of operations during the three months ended March 31, 2018. Of this amount, $100,389 was allocated to compensation expense and $304,163 was allocated as a change in the fair value of the contingent performance payments. The Company revalued its estimate of the contingent performance payment as of March 31, 2017 based on actual results and projections at the time and determined that current fair value of the contingent performance payments was $366,334 compared to $324,000 as of December 31, 2016. The change in the estimated fair value of contingent performance payable resulted in a $42,334 increase in general and administrative expense in the Company's consolidated statement of operations during the three months ended March 31, 2017. Of this amount, $81,334 was allocated to compensation expense and a gain of $39,000 was allocated as a change in the fair value of the contingent performance payments.
