Introductory Note

On May 24, 2017, we filed a report on Form 8-K (the “Initial Report”) with the Securities and Exchange Commission to report our entry of an amendment to our credit facility to increase the maximum revolving credit amount from $1.0 million to $1.75 million. This Amendment No. 1 on Form 8-K/A (i) amends Item 1.01 of the Initial Report and (ii) adds new disclosure under Item 3.02 to include certain material items relating to the amendment to our credit facility omitted from the Initial Report.

Item 1.01 Entry into a Material Definitive Agreement

As previously reported, effective May 23, 2017, we amended our credit agreement with Permian Pelican, LLC (“Lender”) to increase the maximum revolving credit amount from $1.0 million to $1.75 million.

The amendment also provided for an extension of the final maturity date of the credit facility from December 31, 2018 to December 31, 2019.

In consideration of the increase in the revolving credit facility and the extension of the final maturity date, we agreed to issue to Lender, as an amendment fee, 1,200 shares of our Series A Convertible Preferred Stock. As previously reported, Lender acquired 16,092 shares of Series A Convertible Preferred Stock in consideration for the reduction in our outstanding indebtedness to Lender under the recapitalization transaction completed in January 2017.

Item 3.02 Unregistered Sales of Equity Securities

Effective May 23, 2017, we issued 1,200 shares of our Series A Convertible Preferred Stock to Lender as described in Item 1.01 above. The issuance of such shares was exempt from registration pursuant to the provisions of Section 4(2) of the Securities Act.
