As of August 1, 2013, Fir Tree Capital and Fir Tree REF each own 14,648,826 shares of Series A-2 Convertible Preferred Stock, par value $0.00001 per share (the “Series A-2 Preferred Stock”), of the Issuer, which are convertible in the aggregate into 29,297,652 shares of Common Stock. The Reporting Persons are therefore deemed to beneficially own 29,297,652 shares of Common Stock, of which 14,648,826 shares and 14,648,826 shares, are beneficially owned by each of Fir Tree Capital and Fir Tree REF, respectively, representing 48.9%, 24.5% and 24.5%, respectively, of the issued and outstanding shares of the Common Stock of the Issuer as of August 1, 2013 and as of the filing date of this Schedule 13D.

All of the shares of the Series A-2 Preferred Stock held by Fir Tree Capital and Fir Tree REF have been acquired using the working capital of Fir Tree Capital and Fir Tree REF.

The filing of this statement on Schedule 13D shall not be construed as an admission that Fir Tree Capital or Fir Tree REF is for the purposes of Section 13(d) or 13(g) of the Exchange Act, the beneficial owner of any of the 29,297,652 shares of Common Stock held by the other of them. Pursuant to Rule 13d-4, each of Fir Tree Capital and Fir Tree REF disclaim all such beneficial ownership.

Item 4. Purpose of the Transaction.

On August 1, 2013, the Issuer entered into a Securities Purchase Agreement (the “Purchase Agreement”) with Fir Tree Capital and Fir Tree REF (together, the “Fir Tree Investors”), pursuant to which the Issuer sold to the Fir Tree Investors $34,999,997.64 of newly created (i) Series A-1 Non-Convertible Preferred Stock (the “Series A-1 Preferred Stock”) and (ii) Series A-2 Preferred Stock (together with the Series A-1 Preferred Stock, the “Series A Preferred Stock”). The Series A-1 Preferred Stock is not convertible into Common Stock and each share of Series A-2 Preferred Stock is initially convertible on a one-for-one basis into the Issuer’s Common Stock. The terms, rights and privileges of the Series A Preferred Stock are set forth in the Certificate of Designation, Preferences and Rights of Series A-1 Non-Convertible Preferred Stock and Series A-2 Convertible Preferred Stock, as filed by the Issuer with the Nevada Secretary of State on August 1, 2013 (the “Certificate of Designation”), as further discussed in Item 6 below.

The Reporting Persons purchased the Series A Preferred Stock for investment purposes based on the belief that such securities, when purchased, represented an attractive investment opportunity.

Pursuant to the Certificate of Designation, (i) as long as any shares of Series A-1 Preferred Stock or any shares of Series A-2 Preferred Stock remain outstanding, the Issuer shall not change the number of directors which constitute the Issuer’s board of directors, currently five, without the prior affirmative vote or prior written consent of the Fir Tree Investors except in connection with the automatic board expansion upon an event of default, as further described below, (ii) as long as any shares of Series A-1 Preferred Stock remain outstanding, the Fir Tree Investors, as the holders of a majority of the outstanding shares of Series A-1 Preferred Stock, voting as a separate class, shall be entitled to elect two directors of the Issuer (“Series A-1 Directors”), provided that upon the occurrence of an Event of Default (as defined below) under the Certificate of Designation, the size of the Issuer’s board of directors shall automatically increase to seven and the Fir Tree Investors shall be entitled to elect two additional directors of the Issuer, and (iii) as long as any shares of Series A-2 Preferred Stock remain outstanding, the Fir Tree Investors, as the holders of a majority of the outstanding shares of Series A-2 Preferred Stock, voting as a separate class, shall be entitled to elect the number of directors of the Issuer equal to the difference (but not less than zero) of (x) two minus (y) the number of Series A-1 Directors then able to be elected.

In addition to the foregoing board designation rights, the Certificate of Designation also contains additional protective provisions, including restrictive covenants which prohibit the Issuer and its subsidiaries from taking certain actions without the prior affirmative vote or prior written consent of the Fir Tree Investors. A description of such protective provisions is set forth in Item 6 below.

On August 1, 2013, the Issuer amended its bylaws to, among other things, reflect the board designation rights of the holders of the Series A Preferred Stock.

Except in connection with the board designation rights and protective provisions described above, the holders of the Series A-1 Preferred Stock do not have general voting rights. The holders of the Series A-2 Preferred Stock are entitled to vote, together with the holders of Common Stock as a single class, on all matters on which the holders of Common Stock are entitled to vote.

The Purchase Agreement and the Certificate of Designation contain certain provisions relating to the Fir Tree Investors’ possible acquisition of additional shares of Series A-1 Preferred Stock and Series A-2 Preferred Stock as discussed in Item 6.

The Reporting Persons may participate in and influence the affairs and strategic direction of the Issuer through the exercise of their voting rights with respect to the shares of Series A Preferred Stock owned by the Reporting Persons, through the exercise of their right under the terms of the Certificate of Designation and bylaws to nominate director(s) to serve on the Issuer’s board of directors and as a result of the protective provisions contained in the Certificate of Designation (described in Item 6 below). The summary of certain rights of Fir Tree Capital and Fir Tree REF pursuant to the Certificate of Designation and bylaws described in this Item 4 is qualified in the entirety by the Certificate of Designation and bylaws set forth in Exhibit 3 and Exhibit 8, respectively, and are incorporated in this Item 4 by reference.

Although the Reporting Persons have no specific plan or proposal to acquire additional shares or dispose of shares of the Issuer’s securities, except as provided in the Purchase Agreement and Certificate of Designation, consistent with their investment purpose, the Reporting Persons at any time and from time to time may acquire additional shares of Common Stock or dispose of any or all of their shares of Common Stock depending upon an on-going evaluation of the investment in the Common Stock, prevailing market conditions, the Issuer’s financial condition, business, operations and prospects, other investment opportunities, liquidity requirements of the Reporting Persons and/or other investment considerations.

Also, consistent with the investment purpose, the Reporting Persons may engage in communications with one or more shareholders of the Issuer, one or more officers of the Issuer and/or one or more members of the board of directors of the Issuer and/or one or more representatives of the Issuer regarding the Issuer, including but not limited to its operations, the nomination of directors to the board of directors and the composition of the board of directors. The Reporting Persons may discuss ideas that, if effected, may result in any of the following: the acquisition by persons of additional shares of Common Stock or the disposition of shares of Series A Preferred Stock or Common Stock, if any, held by the Reporting Persons or other persons, an extraordinary corporate transaction involving the Issuer and/or changes in the board of directors or management of the Issuer.

Except to the extent the foregoing may be deemed a plan or proposal, the Reporting Persons have no plans or proposals which relate to, or could result in, any of the matters referred to in paragraphs (a) through (j), inclusive, of the instructions to Item 4 of Schedule 13D. The Reporting Persons may, at any time and from time to time, review or reconsider their position and/or change their purpose and/or formulate plans or proposals with respect thereto and carry out any of the actions or transactions described in paragraphs (a) through (j) of Item 4 of the instructions to this 13D, to the extent deemed advisable by the Reporting Persons.

A further description of the Purchase Agreement and Certificate of Designations is set forth in Item 6 below.

Item 5. Interest in Securities of the Issuer.

(a) Fir Tree beneficially owns 29,297,652 shares of Series A-2 Preferred Stock, of which 14,648,826 shares and 14,648,826 shares, are owned by each of Fir Tree Capital and Fir Tree REF, respectively, which as of August 1, 2013, are convertible in the aggregate into 29,297,652 shares of Common Stock. The Reporting Persons are therefore deemed to beneficially own 29,297,652 shares of Common Stock, of which 14,648,826 shares and 14,648,826 shares, are beneficially owned by each of Fir Tree Capital and Fir Tree REF, respectively, representing 48.9%, 24.5% and 24.5%, respectively, of the issued and outstanding shares of the Common Stock of the Issuer as of August 1, 2013. Such percentages of beneficial ownership of the Reporting Persons were calculated by dividing (i) the respective shares of Common Stock deemed to be beneficially owned by Fir Tree, Fir Tree Capital and Fir Tree REF as of August 1, 2013 (as set forth in the prior sentence) by (ii) 30,699,623 shares of Common Stock (which was the number of shares of Common Stock outstanding as of August 1, 2013, based on information provided to the Reporting Persons by the Issuer and excluding shares of Common Stock issuable upon conversion of the Series B Preferred Stock, discussed below).

Based on information provided to the Reporting Persons by the Issuer, as of August 1, 2013, (i) there are 1,680,492 shares of Series B 6% 2012 Convertible Redeemable Preferred Stock (the “Series B Preferred Stock”) issued and outstanding as of August 1, 2013, (ii) each share of the Series B Preferred Stock is convertible at the holder’s option into one share of Common Stock and (iii) holders of Series B Convertible Preferred Stock, none of whom is related to or affiliated with the Reporting Persons, are entitled to vote together with the holders of Common Stock as a single class on all matters on which the holders of Common Stock are entitled to vote. When calculating the voting power of the Common Stock beneficially owned by the Reporting Persons on an as converted to Common Stock basis including shares of Common Stock issuable upon conversion of the Series B Preferred Stock, the voting power of the shares of Common Stock beneficially owned by Fir Tree, Fir Tree Capital and Fir Tree REF represents 47.5%, 23.8% and 23.8% of the issued outstanding shares of Common Stock, respectively. Such percentages of voting power of the Reporting Persons were calculated by dividing (i) the respective shares of Common Stock deemed to be beneficially owned by Fir Tree, Fir Tree Capital and Fir Tree REF as of August 1, 2013 (as set forth above) by (ii) 32,380,115 shares of Common Stock (which was the number of shares of Common Stock outstanding as of August 1, 2013, based on information provided to the Reporting Persons by the Issuer and includes shares of Common Stock issuable upon conversion of the Series B Preferred Stock).

To the knowledge of the Reporting Persons, the executive officers and directors of Fir Tree, the general partner of Fir Tree Capital and the manager of Fir Tree REF have no beneficial ownership of Common Stock separate from the beneficial ownership held by the Reporting Persons. However, the Reporting Persons have certain rights regarding the disposition of shares of Common Stock held by certain third parties, as and to the extent described in the Housatonic Rights Agreement (as defined below), discussed in Item 6 below. The Reporting Persons disclaim beneficial ownership of the shares of Common Stock subject to the Housatonic Rights Agreement.

(b) Fir Tree, as the investment manager of Fir Tree Capital and Fir Tree REF, has the shared power to vote and dispose of the 29,297,652 shares of Series A-2 Preferred Stock, as well as the shares of Common Stock issuable upon conversion thereof.

To the knowledge of the Reporting Persons, the executive officers and directors of Fir Tree, the general partner of Fir Tree Capital and the manager of Fir Tree REF have no power to vote or to direct the vote, no power to dispose or to direct the disposition, nor shared power to dispose or to direct the disposition of the Common Stock separate from the shares held by the Reporting Persons. However, the Reporting Persons have certain rights regarding the disposition of shares of Common Stock held by certain third parties, as and to the extent described in the Housatonic Rights Agreement, discussed in Item 6 below. The Reporting Persons disclaim beneficial ownership of the shares of Common Stock subject to the Housatonic Rights Agreement.

The filing of this statement on Schedule 13D shall not be construed as an admission that Fir Tree Capital or Fir Tree REF is for the purposes of Section 13(d) or 13(g) of the Exchange Act, the beneficial owner of any of the 29,297,652 shares of Common Stock held by the other of them. Pursuant to Rule 13d-4, each of Fir Tree Capital and Fir Tree REF disclaim all such beneficial ownership.

The Reporting Persons engaged in transactions in the Issuer’s securities in connection with those transactions disclosed in the Current Report on Form 8-K filed by the Issuer on August 7, 2013 (the “8-K”).

(c) The Reporting Persons have not engaged in any transactions in the Issuer’s securities during (x) the sixty days prior to the obligation to file this Schedule 13D, and (y) except for the transactions described in the 8-K and in Item 6 below, the period between August 1, 2013 and the filing date of this Schedule 13D.

(d) Not Applicable.

(e) Not Applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

Securities Purchase Agreement. On August 1, 2013, the Issuer entered into the Purchase Agreement with the Fir Tree Investors, pursuant to which the Issuer sold to the Fir Tree Investors the Series A Preferred Stock as described in Item 4. The signing and closing of the Purchase Agreement occurred on August 1, 2013 (the “Closing”), and the funding occurred on August 2, 2013. The Purchase Agreement contains representations, warranties and covenants of the Issuer and the Fir Tree Investors, including, among others, indemnification obligations of the Issuer for the benefit of the Fir Tree Investors. The terms, rights and privileges of the Series A Preferred Stock are set forth in the Certificate of Designation, discussed further below. At the Closing, the parties also executed and delivered a Registration Rights Agreement for the benefit of the Fir Tree Investors, discussed further below. Among other terms, the Purchase Agreement provides that, at any time until December 31, 2014, the Issuer has the conditional right to put to the Fir Tree Investors up to $25,000,000, in whole increments of $1,000,000, of additional shares of Series A-1 Preferred Stock, the proceeds of which shall be used to fund acquisitions, if such acquisition and put exercise is approved by the Fir Tree Investors, in their sole discretion. The conditional put is subject to satisfaction of certain other conditions set forth in the Purchase Agreement. In connection with each issuance of $1,000,000 of Series A-1 Preferred Stock, the Issuer will issue to the Fir Tree Investors shares of Series A-2 Preferred Stock convertible into 1.36% of the Common Stock on a fully diluted basis.

Series A-1 and Series A-2 Preferred Stock. The terms, rights and privileges of the Series A Preferred Stock are set forth in the Certificate of Designation. Set forth below are summaries of the respective voting powers, designations, preferences and other special rights, and qualifications, limitations and restrictions of, the Series A Preferred Stock. Any and all rights, preferences and obligations set forth below which are applicable to the Fir Tree Investors will also be applicable to any successors or assigns of the Fir Tree Investors.

Rank. The Series A-1 Preferred Stock ranks, with respect to dividend payments and distributions of the Issuer’s assets upon a Liquidation Event (as defined below), senior to (i) the Series A-2 Preferred Stock, the Series B Preferred Stock, the Common Stock and certain membership interests in a subsidiary of the Issuer, which are held by third parties (the “Minority Interests”), and all other now or subsequently existing classes and series of capital stock of the Issuer; and (ii) any other equity or equity-linked securities, unless approved by the Fir Tree Investors. The Series A-2 Preferred Stock ranks with respect to dividend payments and distributions of the Issuer’s assets upon a Liquidation Event, (a) junior to the Series A-1 Preferred Stock, (b) senior to the Series B Preferred Stock, the Common Stock, the Minority Interests and all other now or subsequently existing classes and series of capital stock of the Issuer, and (c) except for the Series A-1 Preferred Stock, senior to any other equity or equity-linked securities unless approved by the Fir Tree Investors.

Preference. The preferences of each share of Series A-1 Preferred Stock and Series A-2 Preferred Stock, respectively, with respect to dividend payments and distributions of the Issuer’s assets upon a Liquidation Event, are equal to the preferences of every other share of Series A-1 Preferred Stock and Series A-2 Preferred Stock, respectively, from time to time outstanding, in every respect.

Dividends. The holders of Series A-1 Preferred Stock are entitled to receive cumulative dividends quarterly in arrears at a rate, based on the Series A-1 Stated Value (as defined below), of (a) 9% per annum, or upon the occurrence of an Event of Default (as defined below), 15% per annum, for each of the first three one-year periods commencing on August 1, 2013, (b) 11% per annum, or upon the occurrence of an Event of Default, 17% per annum, for the one-year period commencing on August 1, 2016, and (c) 13% per annum, or upon the occurrence of an Event of Default, 19% per annum, for the one-year period commencing on August 1, 2017 (the “Series A-1 Preferred Dividends”). The Series A-1 Preferred Dividends are payable in cash or, if prohibited from paying in cash under applicable Nevada law or by the terms of the Issuer’s Senior Debt (as defined below), then in-kind through issuance of an equivalent number of shares of Series A-1 Preferred Stock. The holders of Series A-2 Preferred Stock are not entitled to receive dividends, except that the Series A-2 Preferred Stock shall participate in any dividends that may be declared on the Common Stock on an as-converted basis.

The holders of Common Stock are not permitted to receive dividends in respect of the Common Stock during any fiscal year unless and until all outstanding Series A-1 Preferred Dividends have been paid or declared and set apart in cash for payment.

Liquidation Rights. Upon the occurrence of a Liquidation Event, (a) the holders of the Series A-1 Preferred Stock are entitled to receive, on a pro rata basis, prior to any distribution of any of the assets or surplus funds to the holders of Series A-2 Preferred Stock, Series B Preferred Stock, Common Stock, the Minority Interests, or any other class or series of capital stock, an amount equal to (the “Series A-1 Preference Payment”): (x) the then-current Series A-1 Stated Value, plus (y) all Series A-1 Preferred Dividends accrued but unpaid thereon, whether or not declared, together with any other dividends declared but unpaid thereon, plus (z) if any, the applicable Series A-1 Premium (as defined below), and (b) subject to the rights of the Fir Tree Investors as holders of Series A-1 Preferred Stock, the Fir Tree Investors as holders of the Series A-2 Preferred Stock are entitled to receive, on a pro rata basis, prior to any distribution of any of the assets or surplus funds to the holders of the Series B Preferred Stock, the Common Stock, the Minority Interests, or any other class or series of capital stock (other than the Series A-1 Preferred Stock), for each share of Series A-2 Preferred Stock, an amount equal to (the “Series A-2 Preference Payment”) the quotient of (x) the greatest of (A) the fair market value of the Issuer, (B) the Threshold TCF (as defined below), and (C) 200% of the aggregate dollar amount of consideration actually paid by all of the Fir Tree Investors to the Issuer in consideration of the Series A-1 Preferred Stock and Series A-2 Preferred Stock issued to the Fir Tree Investors, divided by (y) the number of shares of Common Stock on a fully diluted basis as of the close of business on the last day of the last fiscal quarter that ended immediately preceding such date.

Voting Rights. The Certificate of Designation also contains certain provisions relating to voting rights of the Series A Preferred Stock and the rights of Fir Tree Capital and Fir Tree REF to designate directors as discussed in Item 4 above. Prior to the closing of Series A Preferred Stock transaction, effective August 1, 2013, Messrs. Sebastien Koechli and Gert Rieder resigned from the Issuer’s Board. Neither Mr. Koechli nor Mr. Rieder expressed any disagreements with the Issuer in connection with their respective resignations. On August 2, 2013, the Fir Tree Investors elected Messrs. Scott Troeller and Jarret Cohen, both executives of Fir Tree, as the Series A-1 Directors.

Additionally, the Certificate of Designation contains provisions which, so long as any shares of the Series A-1 Preferred Stock or the Series A-2 Preferred Stock are outstanding, prohibit the Issuer and its subsidiaries from taking certain actions without the prior affirmative vote or prior written consent of the Fir Tree Investors. The following is a summary of those actions:

Notwithstanding the above restricted actions, the Issuer has the right, without the approval of the Fir Tree Investors, to issue and sell equity securities ranking junior to the Series A-1 Preferred Stock and the Series A-2 Preferred Stock provided that certain conditions are satisfied, including, among other things, that: (a) the securities to be issued are on terms and conditions more favorable to the Issuer and its stockholders than the Series A-1 Preferred Stock and Series A-2 Preferred Stock, as determined in good faith by a committee of the Issuer’s board of directors consisting solely of directors who are not also employees or officers or the Issuer and based on a written opinion of a nationally recognized financial advisor to such committee, which advisor and opinion shall be acceptable to the Fir Tree Investors; (b) the Fir Tree Investors have a right of first refusal with respect to such offering, and if all of the Fir Tree Investors decline to exercise such right, they shall be entitled to exercise their full pre-emptive rights with respect to such offering; (c) the purchaser(s) in such offering shall have specified eligibility criteria and such other criteria as the Issuer and the Fir Tree Investors may mutually agree at the time of such offering; (d) the Fir Tree Investors shall be entitled to the benefit of any anti-dilution protection provided in the Certificate of Designation; and (e) unless waived by the Fir Tree Investors in their sole discretion, the number of shares of Common Stock, together with all shares underlying such securities, issued in such offering (together with (x) all other offerings of securities junior to the Series A-1 Preferred Shares and Series A-2 Preferred Shares and (y) all offerings during the 12 consecutive calendar month period ending with such offering) is less than 15% of the shares of Common Stock on a fully diluted basis.

Conversion. Each share of the Series A-2 Preferred Stock is convertible at any time, at the holder’s option, into such number of fully paid and nonassessable shares of Common Stock as is obtained by dividing the notional value of such share (initially set at $1.00 per share, subject to adjustment for splits, dividends, and the like) then in effect by the initial conversion price of $1.00. Subject to certain customary exceptions, conversion price is subject to adjustment upon certain events, including, without limitation, an investment if the Issuer sells or is deemed to sell, securities for a price per share less than the then current conversion price.

Right of First Refusal on Future Financings; Preemptive Rights. The Certificate of Designation provides the holders of Series A-2 Preferred Stock with a right of first refusal in the event the Issuer desires to raise capital through any equity or debt financing transaction. For as long as any shares of Series A-2 Preferred Stock are outstanding, the Issuer is obligated to deliver to the holders of Series A-2 Preferred Stock a term sheet containing all of the significant terms of the proposed financing, which shall constitute an irrevocable offer to such holders, for a period of 15 days, to elect to provide the entire financing on the proposed terms. If such holders do not validly exercise their right to participate in the entire proposed financing, the Issuer shall have the right to consummate such financing on the proposed terms, subject to the preemptive rights of the holders of Series A-2 Preferred Stock, described below, and the other terms and conditions set forth in the Certificate of Designation. The foregoing right of refusal terminates if the holders of Series A-2 Preferred Stock collectively cease to own Series A-2 Preferred Stock or any other convertible securities of the Issuer equal to at least 10% of the Common Stock calculated on a fully diluted basis.

Pursuant to the Certificate of Designation, if the Issuer determines to consummate a third-party equity or debt financing as described above, then, to the extent the holders of the Series A-2 Preferred Stock do not exercise their right of first refusal in full, each holder of Series A-2 Preferred Stock has the preemptive right, with a right of over-subscription, to purchase up to such holder’s pro rata share of the securities, on the same terms and conditions being offered in the proposed financing (so that after giving effect to such purchase, each holder of Series A-2 Preferred Stock will own the same percentage of the capital stock of the Issuer (calculated on a fully diluted basis) that it owned immediately prior thereto).

Information Rights. The holders of the Series A Preferred Stock are entitled to certain information rights under the Certificate of Designation in the event that the Issuer is not subject to the periodic reporting requirements of Section 13(a) or 15(d) of the Exchange Act.

Redemptions of Series A-1 Preferred Stock. Subject to applicable state law, each holder of Series A-1 Preferred Stock has the option, at any time after the earlier to occur of August 1, 2018 and the occurrence of an Event of Default, to redeem all or any portion of the Series A-1 Preferred Stock at a price equal to the aggregate Series A-1 Preference Payment. Subject to applicable state law, the Issuer also has the right to redeem all (but not less than all) of the outstanding shares of Series A-1 Preferred Stock at any time after August 1, 2013, at a price equal to the aggregate Series A-1 Preference Payment.

Redemptions of Series A-2 Preferred Stock. Subject to applicable state law, each holder of Series A-2 Preferred Stock has the option, at any time during the period beginning on August 1, 2018 and ending on August 1, 2020, or immediately upon customary liquidation events, to redeem all or any portion of the Series A-2 Preferred Stock at a price equal to the Series A-2 Preference Payment as of the close of business on the last day of the last fiscal quarter then ended immediately preceding such date; provided, however, if certain conditions with the respect to the listing of the Common Stock and the Issuer’s market capitalization and trading volume are satisfied at the time of redemption, the Issuer may seek to arrange for an alternate disposition of the Series A-2 Preferred Stock in lieu of such redemption through arranged block trades, privately negotiated sales or registered offerings.

Sale Transaction. In the event (x) a holder of Series A-2 Preferred Stock exercises its optional right of redemption, discussed above, and the Issuer has not redeemed all of the shares of Series A-2 Preferred Stock subject to redemption on the required date, and such redemption remains uncompleted on the first anniversary thereof, or (y) the Issuer has sought to arrange for the alternate disposition of the Series A-2 Preferred Stock described above and all of the Series A-2 Preferred Stock subject thereto have not been sold by the date that is 18 months after the date the Issuer delivered notice of alternate disposition, then, in each case, the Fir Tree Investors have the right to initiate and compel a sale of the entire Issuer (a “Sale Transaction”).
