Dear Kevin Cox:

The Listing Rules (the “Rules”) require listed securities to maintain a minimum Market Value of Listed Securities (MVLS) of $35 million.¹ Based upon our review of the Company’s MVLS for the last 30 consecutive business days, the Company no longer meets this requirement.² Consequently, a deficiency exists with regard to the Rule.³ However, the Rules also provide the Company a compliance period of 180 calendar days in which to regain compliance. The following table summarizes the critical dates and information as related to this matter.

If at anytime during this compliance period the Company’s MVLS closes at $35 million or more for a minimum of ten consecutive business days, we will provide you written confirmation of compliance and this matter will be closed.⁴

¹ Staff calculates MVLS based upon the most recent Total Shares Outstanding (TSO), multiplied by the closing bid price.

² For online access to all Nasdaq Rules, please see “Nasdaq Online Resources,” included with this letter.

³ Staff notes that the Company also does not meet the requirements under Listing Rules 5550(b)(1) and 5550(b)(3).

⁴ Listing Rule 5810(c)(3)(H) states in part, “Staff may, in its discretion, require a Company to satisfy the applicable Price-based Requirement for a period in excess of ten consecutive business days, but generally no more than 20 consecutive business days, before determining that the Company has demonstrated an ability to maintain long-term compliance.”

In the event the Company does not regain compliance with the Rule prior to the expiration of the compliance period, it will receive written notification that its securities are subject to delisting.⁵

Our Rules require that the Company promptly disclose receipt of this letter by either filing a Form 8-K, where required by SEC rules, or by issuing a press release. The announcement needs to be made no later than four business days from the date of this letter and must include the continued listing criteria that the Company does not meet, and a description of each specific basis and concern identified by Nasdaq in reaching the determination.⁶ The Company must also submit the announcement to Nasdaq’s MarketWatch Department.⁷ If the public announcement is made between the hours of 7:00 AM and 8:00 PM Eastern Time, the Company must submit the announcement to Nasdaq’s MarketWatch Department at least ten minutes prior its public release. If the public announcement is made outside of these hours, the Company must submit the announcement prior to 6:50 A.M. Eastern Time. Please note that if you do not make the required announcement trading in your securities will be halted.⁸

Finally, an indicator will be displayed with quotation information related to the Company’s securities on NASDAQ.com and NASDAQTrader.com and may be displayed by other third party providers of market data information. Also, a list of all non-compliant Nasdaq companies and the basis for such non-compliance is posted on our website at listingcenter.nasdaq.com. The Company will be included in this list commencing five business days from the date of this letter.

If you have any questions, please contact me at +1 202 384 8056.
