Amendment No. 5 to Schedule 13D

This Amendment No. 5 (“Amendment”) amends and supplements the Schedule 13D filed with the SEC on September 27, 2013, as previously amended by the Schedule 13D/A filed with the SEC on January 17, 2014, as previously amended by the Schedule 13D/A filed with the SEC on July 2, 2015, as previously amended by the Schedule 13D/A filed with the SEC on December 29, 2015, and as previously amended by the Schedule 13D/A filed with the SEC on March 23, 2016 (the “Schedule 13D”). Except as set forth in this Amendment, the Schedule 13D remains unchanged. Unless otherwise indicated, all capitalized terms used herein but not defined herein shall have the same meaning as set forth in the Schedule 13D.

The following items of the Schedule 13D are hereby amended as follows:

ITEM 4. PURPOSE OF TRANSACTION

The Filers hereby add the following supplemental disclosure to Item 4:

Asset Purchase Agreement

In connection with the previously disclosed Chapter 11 Filings of the Issuer, on April 8, 2016, the Issuer entered into an Asset Purchase Agreement (the “APA”) with Douglas Acquisitions, the K&M Douglas Trust and the James Douglas and Jean Douglas Irrevocable Descendant’s Trust (collectively, the “Purchasers”). Pursuant to the APA, the Purchasers have agreed to acquire substantially all of the assets of the Issuer (the “Purchased Assets”), subject to the terms and conditions of the APA, in a sale pursuant to section 363 of the Bankruptcy Code. Under the APA, the Purchasers have agreed to acquire the Purchased Assets for aggregate consideration including: (i): the amount required to satisfy the Issuer’s obligations to Western Alliance Bank; (ii) the amount required to satisfy the Issuer’s obligations to Douglas Acquisitions in connection with the previously disclosed DIP Credit Agreement; (iii) the amount required to satisfy the Issuer’s obligations to the holders of the Convertible Notes and the Series B Notes; (iv) the amount required to pay any cure amounts associated with assumption of the Issuer’s executory contracts; (v) $250,000 in cash; and (vi) assumption of certain liabilities of the Issuer.

The purchase price will be paid with a combination of cash and a credit bid of the Issuer’s obligations pursuant to the DIP Credit Agreement, as well as a credit bid of the Issuer’s obligations pursuant to the Convertible Notes and Series B Notes held by the K&M Douglas Trust and the James Douglas and Jean Douglas Irrevocable Descendant’s Trust.

Under the Chapter 11 Filings and in connection with the APA, the Issuer will seek approval of a bidding and public auction process for the Purchased Assets pursuant to section 363 of the Bankruptcy Code. The APA is subject to higher or better offers made in accordance with bidding procedures subject to the Bankruptcy Court’s approval.

The APA is subject to Bankruptcy Court approval and the consummation of the acquisition is subject to multiple bankruptcy conditions and milestones.

The APA may be terminated for, among other events, failure to satisfy multiple bankruptcy conditions and milestones, mutual agreement to terminate the APA, the delivery by the Purchasers of a notice of termination within 28 days of Purchasers’ receipt of the disclosure schedules, or the failure to close by July 15, 2016. If the Company consummates an alternative transaction, the Purchasers will generally be entitled to a breakup fee of two percent of the purchase, provided that the purchase price is over $25 million, plus reimbursement of fees and expense up to a maximum of $300 thousand.

The foregoing description of the APA is qualified in its entirety by reference to the full text of the Asset Purchase Agreement, a copy of which is filed herewith as Exhibit 7.14 and incorporated herein by reference.

ITEM 6. CONTRACTS, AGREEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER.

The information disclosed in Item 4 above is incorporated herein by reference.

ITEM 7. MATERIALS TO BE FILED AS EXHIBITS
