Terms defined in the 13D Filing are used in this Amendment No. 6 as so defined, unless otherwise defined in this Amendment No. 6.

The Reporting Persons are party to certain agreements with Infrastructure and Energy Alternatives, LLC, Oaktree Power Opportunities Fund III Delaware, L.P. and OT POF IEA Preferred B Aggregator, L.P. (the “Oaktree Entities”), which agreements contain, among other things, agreements as to the issuance of Warrants and preferred stock of the Issuer, an agreement pursuant to which certain of the Oaktree Entities will exchange Series A Preferred Stock (as defined herein) for Warrants and Series B-3 Preferred Stock (as defined herein), an agreement pursuant to which the Reporting Persons and certain of the Oaktree Entities must vote in favor of a Redemption Sale (as defined herein) under certain circumstances and consents relating to the Rights Offering (as defined herein), each as further described in Item 6 below.  As a result, the Reporting Persons may be deemed to be members of a “group”, within the meaning of Section 13(d)(3) of the Act, comprised of the Reporting Persons and the Oaktree Entities.  The Reporting Persons expressly disclaim any membership in a group with the Oaktree Entities.  It is the understanding of the Reporting Persons that the Oaktree Entities are filing a separate Schedule 13D with respect to the shares of Common Stock beneficially owned by the Oaktree Entities.  The beneficial ownership of the Reporting Persons does not include any shares of Common Stock that may be beneficially owned by any of the Oaktree Entities, and the Reporting Persons disclaim beneficial ownership over such shares.

Item 2. Identity and Background

The last sentence of Item 2(a) of the 13D Filing is hereby amended and restated as follows:

The Reporting Persons have entered into a joint filing agreement, dated as of January 27, 2020, a copy of which is attached hereto as Exhibit 99.7.

Schedule A referenced in Item 2(c) of the 13D Filing is hereby amended and restated as the Schedule A attached to this Amendment No. 6.

Item 4. Purpose of Transaction

The first paragraph of Item 4 of the 13D Filing is hereby amended and restated as follows:

Pursuant to the terms of the Series B Certificates (as defined herein), Ares Management LLC, on behalf of its affiliated funds, investment vehicles and/or managed accounts (“Ares”), has the right to designate and appoint: (x) one director to the Issuer’s board of directors (the “Board”) for so long as Ares and its affiliates hold at least 50% of the Series B-1 Preferred Stock (as defined herein) issued to Ares and its affiliates on the Closing Date (as defined herein) (such director, the “First Series B Director”) and (y) an additional director for so long as Ares and its affiliates hold at least 50% of the Series B-2 Preferred Stock (as defined herein) issued to Ares on the Second ECA Closing Date (as defined herein) (such director, the “Second Series B Director”).  Notwithstanding the foregoing, pursuant to the terms of the Waiver Agreement, dated as of January 23, 2020, by and between Ares and the Issuer (the “Waiver Agreement”), Ares agreed only to appoint either the First Series B Director or the Second Series B Director, but not both, for as long as the following conditions remain satisfied:

·The size of the Board is comprised of seven (7) or fewer individuals;

·At least three (3) of the directors on the Board qualify as independent pursuant to guidance from the United States Securities and Exchange Commission and the rules of the applicable stock exchange;

·Ares is entitled to appoint both the First Series B Director and the Second Series B Director;

14

·Each of the stockholders of the Issuer and their respective affiliates with specific Board designation rights as of the date of the Waiver Agreement (other than Ares and its affiliates) is entitled to appoint no more than one director to the Board; and

·No other stockholder of the Issuer (other than the stockholders of the Issuer as of the date of the Waiver Agreement) is entitled to appoint any director to the Board.

If, at any time, any of the conditions set forth above are no longer satisfied, the Waiver Agreement shall automatically terminate and be of no further force and effect.

The Reporting Persons have not yet exercised their right to appoint either the First Series B Director or the Second Series B Director.

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

Item 6 of the 13D Filing is hereby amended by adding the following disclosure after the second to last paragraph under “C. October 2019 Transactions—Amended and Restated Series B-1 Certificate and Amended and Restated Series B-2 Certificate”:

As described in Item 4 above, so long as Ares and its affiliates hold at least 50% of the Series B-1 Preferred Stock initially issued to Ares and its affiliates on the Closing Date, the Series B-1 Certificate provides Ares with the right to designate and appoint the First Series B Director.

In addition, under the Series B-2 Certificate, from and after September 13, 2019, as long as Ares and its affiliates hold at least 50% of the Series B-2 Preferred Stock issued to Ares and its affiliates on the Second ECA Closing Date, Ares will have the right to designate and appoint the Second Series B Director.

Pursuant to the terms of the Waiver Agreement, and notwithstanding the foregoing, Ares agreed only to appoint either the First Series B Director or the Second Series B Director, but not both, for as long as the following conditions remain satisfied:

·The size of the Board is comprised of seven (7) or fewer individuals;

·At least three (3) of the directors on the Board qualify as independent pursuant to guidance from the United States Securities and Exchange Commission and the rules of the applicable stock exchange;

·Ares is entitled to appoint both the First Series B Director and the Second Series B Director;

·Each of the stockholders of the Issuer and their respective affiliates with specific Board designation rights as of the date of the Waiver Agreement (other than Ares and its affiliates) is entitled to appoint no more than one director to the Board; and

·No other stockholder of the Issuer (other than the stockholders of the Issuer as of the date of the Waiver Agreement) is entitled to appoint any director to the Board.

If, at any time, any of the conditions set forth above are no longer satisfied, the Waiver Agreement shall automatically terminate and be of no further force and effect.

If at any time, any of the conditions set forth in clauses (i) through (v) of the immediately foregoing sentence is no longer satisfied, this waiver agreement shall automatically terminate and be of no further force and effect.

Without limiting the generality of the foregoing and without limiting anything set forth in the CODs, the Corporation agrees with Ares to, if applicable, include the First Series B Director or Second Series B Director, as applicable, in the slate of nominees recommended by the Board and to use its reasonable best efforts to cause the election of such First Series B Director or Second Series B Director, as applicable, to the Board, including, without limitation, nominating the First Series B Director or Second Series B Director, as applicable, to be elected as a director of the Corporation, recommending election and soliciting proxies or consents in favor thereof, in each case subject to applicable law.

Except as specifically set forth herein, nothing contained in this waiver agreement shall be deemed to diminish or modify any rights of Ares or any obligations of the Corporation set forth in the CODs.

This waiver agreement is intended to bind and inure to the benefit of the parties hereto and their respective successors and assigns. This waiver agreement shall be governed by and construed in accordance with the laws of the State of Delaware.
