Amendment No. 6 to Schedule 13D

This Amendment No. 6 (“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, as previously amended by the Schedule 13D/A filed with the SEC on March 23, 2016, and as previously amended by the Schedule 13D/A filed with the SEC on April 14, 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:

DIP Credit Agreement

On May 23, 2016, the Issuer and Douglas Acquisitions entered into a Third Amendment to the DIP Credit Agreement (the “Third DIP Amendment”) that increased the commitment amount under the DIP Credit Agreement from $6.0 million to $7.636 million. In addition, on June 1, 2016, the Issuer and Douglas Acquisitions entered into a Fourth Amendment to the DIP Credit Agreement (the “Fourth DIP Amendment”) that increased the commitment amount under the DIP Credit Agreement to $9.0 million.

On July 13, 2016, in connection with the closing of the APA, discussed below, all of the Issuer’s obligations to Douglas Acquisitions under the DIP Credit Agreement, as amended, were satisfied by offset against the purchase price paid by Douglas Communications under the APA.

Asset Purchase Agreement

On April 22, 2016, the Issuer and the Purchasers entered into the First Amendment to Asset Purchase Agreement (the “First Amendment”) providing technical amendments to the previously disclosed APA. On May 31, 2016, the Issuer and the Purchasers entered into the Second Amendment to Asset Purchase Agreement (the “Second Amendment”) which, among other things, (i) amended the definition of Excluded Assets to include in such definition avoidance claims the Issuer may have under the Bankruptcy Code or applicable state law including, without limitation, claims under Chapter 5 of the Bankruptcy Code, (ii) requires the Purchasers to provide certain benefits to employees of the Issuer hired by the Issuer, (iii) revised the purchase price formula that would trigger payment of the break-up fee potentially payable to the Purchasers, and (iv) extended the due diligence deadline to June 1, 2016. On July 12, 2016, the Issuer and the Purchasers entered into the Third Amendment to Asset Purchase Agreement (the “Third Amendment”) which, among other things, provides that the schedule of Assumed Executory Contracts may be amended for a period of up to 60 days following the closing.

On July 13, 2016, the closing of the APA, as amended by the First Amendment, the Second Amendment and Third Amendment occurred and the Purchased Assets were transferred to Douglas Acquisitions. In accordance with the closing, among other things, all of the Issuer’s obligations with respect to the Convertible Notes and the Series B Notes held by the K&M Douglas Trust and the James Douglas and Jean Douglas Irrevocable Descendant’s Trust were satisfied by offset against the purchase price. In addition, the Convertible Notes held by Mr. McGaw were paid off by the Purchasers pursuant to the closing of the APA. As a result of the closing of the APA, the Filers no longer beneficially own the Convertible Notes and the Series B Notes or the Common Stock issuable upon conversion of the Convertible Notes and the Series B Notes.

The foregoing description of the Third DIP Amendment is qualified in its entirety by reference to the full text of the Third DIP Amendment, a copy of which is attached to the Issuer’s Current Report on Form 8-K filed with the Securities and Exchange Commission on May 27, 2016, as Exhibit 10.1 and incorporated herein by reference. The foregoing description of the First Amendment is qualified in its entirety by reference to the full text of the First Amendment, a copy of which is attached to the Issuer’s Current Report on Form 8-K filed with the Securities and Exchange Commission on April 25, 2016, as Exhibit 10.2 and incorporated herein by reference. The foregoing descriptions of the Fourth DIP Amendment and the Second Amendment are qualified in their entirety by reference to the full text of the Fourth DIP Amendment and the Second Amendment, copies of which are attached to the Issuer’s Current Report on Form 8-K filed with the Securities and Exchange Commission on June 3, 2016, as Exhibits 10.1 and 10.2, respectively, and incorporated herein by reference.

ITEM 5.

INTERESTS IN SECURITIES OF THE ISSUER.

The Filers update the disclosure in this Item 5 as follows:

The beneficial ownership of the Common Stock by each Filer at the date hereof is reflected on that Reporting Person’s cover page.

Other than the cancellation of the Convertible Notes and Series B Notes as described in Item 4 above, none of the Filers has effected any transaction in the Common Stock during the past 60 days.

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.
