This Amendment No. 3 amends and supplements the statement on Schedule 13D originally filed by the Reporting Persons with the Securities and Exchange Commission (the “SEC”) on August 25, 2014 (the “Original 13D”), as amended and supplemented by Amendment No.1 filed by the Reporting Persons with the SEC on March 23, 2015 (“Amendment No.1”) and Amendment No.2 filed by the Reporting Persons with the SEC on September 10, 2015 (“Amendment No.2” and, together with the Original 13D and Amendment No.1 the “Existing Schedule 13D”).

Item 3. Source and Amount of Funds or Other Consideration.

Item 3 of the Existing Schedule 13D is hereby amended and restated in its entirety as follows:

On August 14, 2014, AC Midwest, the Issuer and the Issuer’s wholly-owned subsidiary, MES, Inc., a North Dakota corporation (“MES”), entered into a series of agreements, including a certain Financing Agreement (the “Original Financing Agreement”), pursuant to the terms of which AC Midwest purchased from the Issuer a 12% senior secured convertible note in the principal amount of $10 million, due July 31, 2018 (the “Original Note”), and a five year warrant (the “Original Warrant”) to purchase up to an additional 12,500,000 shares of Common Stock.

The source of funding for this transaction was derived from capital contributed to Fund II and borrowings under a capital call facility with Silicon Valley Bank (the “Line of Credit”).

On March 16, 2015, AC Midwest, the Issuer and MES entered into series of amendments related to the Original Financing Agreement, including (i) a Wavier and Amendment to Financing Agreement and Reaffirmation of Guaranty (the “First Financing Agreement Amendment”), pursuant to which the Issuer made a $3 million payment toward the principal balance of the Original Note and the conversion price of the Original Note was adjusted to $0.50 per share of Common Stock, and (ii) an amendment to the Original Warrant, pursuant to which the exercise price of the Original Warrant was adjusted to $0.50 per share of Common Stock. The Original Warrant remains subject to percentage based anti-dilution protection requiring that the aggregate number of shares of Common Stock purchasable upon its initial exercise not be less than an amount equal to 15% of the Issuer’s then outstanding shares of capital stock on a fully diluted basis.

On November 16, 2015, AC Midwest, the Issuer and MES entered into a second series of amendments related to the First Financing Agreement Amendment (the “Second Financing Agreement Amendment” and, together with the Original Financing Agreement and First Financing Agreement Amendment, the “Financing Agreement”), pursuant to which AC Midwest purchased from the Issuer an additional 12% senior secured convertible note in the principal amount of $600,000 with a conversion price of $0.50 per share of Common Stock (the “New Note” and, together with the Original Note, the “Notes”), and a five year warrant to purchase up to an additional 5,000,000 shares of Common Stock at an exercise price of $0.35 per share of Common Stock (the “New Warrant” and together with the Original Warrant, the “Warrants”).

Subject to certain conditions precedent, the Second Financing Agreement Amendment also requires AC Midwest to purchase up to two additional 12% senior secured convertible notes, in an aggregate principal amount of up to $1,400,000, prior to July 2016 (the “Additional New Notes”).

The source of funding for this transaction was derived from borrowings under the Line of Credit pending capital contributions.

Item 4. Purpose of Transaction.

The first three paragraphs of Item 4 of the Existing Schedule 13D are hereby amended and restated in their entirety and supplemented as follows:

(a)-(j) The Notes and Warrants were acquired for investment purposes.

Pursuant to, and in accordance with the terms of the Financing Agreement, the indebtedness evidenced by the Notes is convertible at any time and from time to time into shares of the Issuer’s Common Stock at an initial conversion price of $0.50 per share, subject to weighted average anti-dilution protection (except with respect to certain excluded issuances). Interest on the Notes is payable at a rate of 2% in cash and 10% in kind (the “PIK Interest”) through August 13, 2016 and thereafter is payable entirely in cash. Interest is calculated on the basis of a 360-day year and actual days elapsed, and it accrues or is payable, as applicable, monthly in arrears on or before the last day of each calendar month.

As of November 19, 2015, the outstanding principal balance of the Notes together with all accrued interest thereon was $8,912,573. An additional $149,136 of PIK Interest will accrue and become payable on the Notes through January 18, 2016.

The Original Warrant is exercisable at any time and from time to time for up to 12,500,000 shares of Common Stock at an initial exercise price of $0.50 per share of Common Stock, subject to weighted average anti-dilution protection (except with respect to certain excluded issuances). In addition, the Original Warrant is subject to percentage based anti-dilution protection requiring that the aggregate number of shares of Common Stock purchasable upon its initial exercise not be less than an amount equal to 15% of the Issuer’s then outstanding shares of capital stock on a fully diluted basis.

The New Warrant is exercisable at any time and from time to time for up to 3,600,000 shares of Common Stock at an initial exercise price of $0.35 per share of Common Stock, subject to weighted average anti-dilution protection (except with respect to certain excluded issuances). The New Warrant will become exercisable for up to the remaining 1,400,000 shares of Common Stock in proportion to the principal amount of Additional New Notes purchased by AC Midwest and at the time of issuance of such Additional New Notes. The New Warrant is also subject to percentage based anti-dilution protection, requiring that the aggregate number of shares of Common Stock purchasable upon any exercise date not be less than an amount equal to 0.12% per 100,000 shares of Common Stock purchasable of the Issuer’s then outstanding shares of capital stock on a fully diluted basis

The Warrants may also be exercised on a cashless basis.

Item 5. Interest in Securities of the Issuer.

Item 5 of the Existing Schedule 13D is hereby amended and restated in its entirety as follows:

(a), (b) Based on the Issuer’s Quarterly Report on Form 10-Q for the period ended September 30, 2015, as filed with the SEC on November 16, 2015, an aggregate of 47,194,118 shares of Common Stock were issued and outstanding as of November 16, 2015.

Based on the foregoing, as of November 16, 2015, the Reporting Persons may be deemed to be the beneficial owners of an aggregate of 34,223,418 shares of Common Stock, which includes: (i) 17,825,145 shares of Common Stock issuable upon conversion of the Notes (the “Conversion Shares”); (ii) 298,273 shares of Common Stock issuable upon conversion of PIK Interest that will accrue on and become payable under the Notes within sixty days of the date hereof (the “PIK Interest Shares”); and (iii) 16,100,000 shares of Common Stock issuable upon exercise of the Warrants (the “Warrant Shares” and together with the Notes, Conversion Shares, Warrants, PIK Interest Shares, any 2013 Secured Notes acquired by AC Midwest, and any shares of Common Stock issuable upon conversion of any 2013 Secured Notes so acquired, collectively, the “Subject Securities”), representing approximately 42.03% of the Issuer’s outstanding Common Stock.

AC Midwest directly holds (or upon issuance or acquisition, as applicable, will directly hold) and has the power to vote and dispose of the Subject Securities.

Fund II, owns all of the outstanding equity interests of AC Midwest, accordingly Fund II may be deemed to beneficially own the Subject Securities held by AC Midwest.

Alterna, in its capacity as investment advisor to Fund II, has the ability to direct the investment decisions of the Fund II, including the power to vote and dispose of securities held by AC Midwest, accordingly Alterna may be deemed to beneficially own the Subject Securities held by AC Midwest.

Fund II General Partner, in its capacity as the general partner of Fund II, has the ability to direct the management of Fund II’s business, including the power to direct the decisions of Fund II regarding the vote and disposition of securities held by AC Midwest, accordingly Fund II General Partner may be deemed to beneficially own the Subject Securities held by AC Midwest.

Each of Messrs. Toll, Furnivall, Press and Miller, by virtue of their role as managing members of Alterna, and Mr. Goldin, by virtue of his role as a member of Alterna, may be deemed to have the shared power regarding the vote and disposition of securities held by AC Midwest, accordingly each may be deemed to beneficially own the Subject Securities held by AC Midwest.
