Description of related party loans				If the Company completes a Business Combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $750,000 of such Working Capital Loans may be convertible into units of the post Business Combination entity at a price of $10.00 per unit, and up to $750,000 of such Working Capital Loans may be converted into warrants of the post Business Combination entity at a price of $1.00 per warrant. The units and warrants would be identical to the Private Placement Units and Private Placement Warrants, respectively. In the event that a Business Combination does not close, the Working Capital Loans would be forgiven except that the Company may use a portion of proceeds held outside the Trust Account, if any, to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans.
