CALCULATION OF FILING FEE

Transaction valuation*	Amount of filing fee**
$ 2,300,000	$ 267.26

* Estimated for purposes of calculating the amount of the filing fee only. Hennessy Capital Acquisition Corp. (the “Company”) is offering holders of up to 5,750,000 of the Company’s warrants exercisable for shares of the Company’s common stock, par value $0.0001 per share (the “Shares”), at an exercise price of $5.75 per half share ($11.50 per whole share), subject to adjustment (the “Warrants”), the opportunity to exchange such Warrants for Shares by tendering one Warrant in exchange for 0.1 of a Share. The transaction value was determined by using the average of the high and low prices of the Warrants as reported on the Nasdaq Capital Market on January 6, 2015, which was $0.40.

** Previously paid. The amount of the filing fee assumes that all 5,750,000 Warrants will be exchanged and is calculated pursuant to Rule 0-11(b) of the Securities Exchange Act of 1934, as amended, which equals $116.20 for each $1,000,000 of the value of the transaction.
