Maxim is acting as sole book-running manager of the offering and as the sole representative of the underwriters named below. Subject to the terms and conditions of the underwriting agreement dated the date of this prospectus, the underwriters named below, through their representative Maxim Group LLC, have severally agreed to purchase on a firm commitment basis, and we have agreed to sell to the underwriters, the following respective number of units set forth opposite the underwriter’s name at a public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus.

| Underwriters    |     | Number of 
 Units     |           |
| Maxim Group LLC |     |           |           |
| Total           |     |           | 5,000,000 |

The underwriting agreement provides that the obligations of the underwriters to purchase the units included in this offering are subject to all applicable laws and regulations and certain conditions precedent such as the receipt by the underwriters of officers’ certificates and legal opinions by their counsel. The underwriters are obligated to purchase all of the units (other than those covered by the over-allotment option described below) if they purchase any of the units. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the underwriting agreement may be terminated. We have agreed to indemnify the underwriters and certain of their controlling persons against certain liabilities, including liabilities under the Securities Act, and to contribute to payments that the underwriters may be required to make in respect of those liabilities.

Units sold by the underwriters to the public will initially be offered at the initial public offering price set forth on the cover of this prospectus. Upon the execution of the underwriting agreement, the underwriters will be obligated to purchase the units at the prices and upon the terms stated therein, and, as a result, will thereafter bear any risk associated with changing the offering price to the public or other selling
