5.       We note your disclosure which states Industrea is expected to be the
accounting acquirer
         in the business combination under both a no redemption and maximum
redemption
         scenario. It appears under a maximum redemption scenario, the existing
public
         shareholders of Industrea would hold no ownership interest in Newco.
Please provide us
         with your analysis in support of your conclusion that Industrea would
be the accounting
         acquirer in a maximum redemption scenario. Refer to the guidance found
in ASC 805-

Question and
         Answer 102.07 of the Commission's Compliance and Disclosure

activities as
         presented in your statement of cash flows. In addition, we are unable
to locate the
         necessary reconciliation for this non-GAAP measure. Please modify your
disclosures
         accordingly.
15.      We note footnote 3 in your tabular presentation references
"out-of-period adjustments" as
         a component of your "Other adjustments" presented to arrive at Pro

adjustments you are

same, please

confusion.
