Under the terms of the Separation Agreement, (a) the Issuer affirmed its obligations and the rights of Buyers (as defined in the Indaba Agreements) under the Indaba Agreements; and (b) the Mast Funds have agreed not to remove or replace either James Parmalee or Matthew Drapkin as an “Initial Investor Director” or “Additional Investor Director”, in each case within the meaning of the Indaba Agreements, unless (i) the notice of removal is prior to the time that the Board (or applicable committee) has resolved to nominate and recommend Mr. Parmelee or Mr. Drapkin for election as a director at a meeting of stockholders of the Issuer, and (ii) such removal is effective as of the conclusion of such meeting of stockholders.

In addition, under the terms of the Separation Agreement on the Effective Date, (a) the Issuer and Mast Capital have agreed that the warrant, dated December 9, 2016, delivered to Mast Capital by the Issuer, is cancelled and replaced by an aggregate of 54,733 shares of Common Stock registered in Mast Capital’s name; (b) the Issuer and Mr. Steinberg have agreed that the Performance Share Award Agreement, dated November 3, 2016, between the Issuer and Mr. Steinberg, granting to Mr. Steinberg 220,923 performance-based restricted shares of Common Stock, is cancelled and forfeited in full; (c) Mr. Steinberg has agreed to voluntarily resign from employment at Great Elm Capital Management, Inc., a Delaware corporation and subsidiary of the Issuer; (d) the Issuer has agreed to grant Mast Capital the New Warrant (as defined in Item 5(a) below), the terms and conditions of which are described in Item 5(a) below; (e) the Issuer has agreed to provide (i) demand registration rights exercisable following the first anniversary of the Effective Date if the New Warrant has been exercised, and (ii) piggy-back registration rights with respect to shares of Common Stock issued or issuable pursuant to the Separation Agreement; (f) the Issuer has, in accordance with its Amended and Restated Certificate of Incorporation (the “Certificate”), approved the acquisition by Mast Capital (or its designee under the New Warrant) of any and all shares of Common Stock contemplated under the Separation Agreement or the New Warrant, and has waived any and all other conditions, notice requirements and other limitations found in Article XIV of the Certificate affecting the acquisition of such shares; (g) the Board has granted an exemption under the Issuer’s Tax Benefits Preservation Agreement, dated as of January 20, 2015, with respect to the acquisition by Mast Capital (or its designee under the New Warrant) of any and all shares of Common Stock contemplated by the Separation Agreement or the New Warrant; and (h) certain parties to the Separation Agreement (including the Issuer and the Reporting Persons) have agreed to mutually release and forever discharge the other releasing parties from any and all liability whatever arising out of, based upon or relating to actions or omissions occurring on or before the Effective Date, subject to certain limitations, including with respect to claims arising from the Separation Agreement, as set forth in the Separation Agreement.

(a) The aggregate percentage of Common Stock reported to be owned by the Reporting Persons is based upon 24,558,614 shares of Common Stock outstanding, which is derived by adding (i) 24,139,631 shares of Common Stock outstanding as of September 1, 2017, as reported in the Issuer’s Form 10-K filed with the Securities and Exchange Commission on September 19, 2017, (ii) the 54,733 shares of Common Stock issued to MAST Capital on the Effective Date pursuant to the terms of the Separation Agreement and (iii) 364,250 shares of Common Stock which could be issuable upon exercise of the New Warrant, as described below.

MAST Capital (i) holds 54,733 shares of Common Stock, which were issued pursuant to the Separation Agreement on the Effective Date, and (ii) as the investment manager of the MAST Accounts, may be deemed to beneficially own 1,947,735 shares of Common Stock held by the MAST Accounts.

As of the date hereof, 364,250 shares of Common Stock could be issuable upon exercise of the New Warrant in compliance with such limitation. The New Warrant is exercisable from the date that is ten trading days following the date of issuance of the New Warrant up to and until the expiration of the Standstill Period. The exercise price for the New Warrant is the simple average of the Weighted Average Price (as defined in the New Warrant) of the Common Stock for the ten consecutive trading days ending on and including the trading day immediately prior to the date of the exercise of the New Warrant. The foregoing description of the New Warrant is qualified in its entirety by reference to the full text of the New Warrant, which is attached as Exhibit 99.2 hereto and incorporated by reference herein.

Mr. Steinberg declaims beneficial ownership of the Common Stock held by MAST Capital except to the extent of his pecuniary interest therein.

(b) MAST Capital and Mr. Steinberg have the shared power to vote and dispose of the Common Stock owned by the MAST Accounts and MAST Capital reported in this Schedule 13D. Mr. Steinberg has the sole power to vote and dispose of the Common Stock directly owned by him reported in this Schedule 13D.

The filing of this Schedule 13D shall not be construed as admission that MAST Capital or Mr. Steinberg is, for the purposes of Section 13(d) or 13(g) of the Act, or otherwise, the beneficial owner of any of the 1,947,735 shares of Common Stock owned by the MAST Accounts or that Mr. Steinberg is, for the purposes of Section 13(d) or 13(g) of the Act, or otherwise, the beneficial owner of any of the shares of Common Stock owned by MAST Capital.
