Default”). Borrower, Agent and Lenders also acknowledge that other Defaults or Events of Default presently may exist

Default that presently exist, collectively, the “Existing Defaults”).


 


1.6          Borrower
acknowledges that such Existing Defaults have not been cured, waived or excused by Agent or Lenders at any time or in any manner;
and that there are no claims, demands, offsets or defenses at law or in equity that would defeat or diminish Agent’s and
each Lender’s present and unconditional right to collect any of the Obligations, and to proceed to enforce the rights and
remedies available to Agent and Lenders as provided in any of the Financing Documents or otherwise at law.


 






    2 


     


    

 


1.7          Borrower has requested that Agent and Lenders provide Borrower a period of forbearance that will enable Borrower, at or prior
to the expiration of such forbearance period, to close certain transactions involving the purchase of additional securities, the
assignment of certain assets and the satisfaction or cancellation of all of the Obligations, together with certain other Obligations
(such transactions, collectively, the “Settlement Transaction”) pursuant to that certain Securities Purchase
Agreement and Loan Satisfaction Agreement dated of even date herewith by and among Borrower and the Lenders (the “Settlement
Agreement”).


 


1.8          In
response to Borrower’s request, and in reliance upon Borrower’s representations made to Agent and Lenders in support
thereof and the other terms and conditions of this Agreement, Agent and Lenders are willing to forbear during the Forbearance
Period (as defined below) from the further exercise of their rights and remedies under the Financing Documents, upon and subject
to the terms and conditions set forth herein, all as more particularly set forth and described in this Agreement. The “Forbearance
Period” as used herein shall refer to that period beginning on the Effective Date and (unless terminated earlier pursuant
to the terms of Section 2.1 below) terminating on the earliest of (i) the closing date for the Settlement Transaction, (ii) the
termination of the Settlement Transaction in accordance with the terms of the Settlement Agreement and (iii) March 31, 2018.


 


1.9          Borrower
also has requested additional loan advances from certain Lenders, consisting of (a) a $1,500,000.00 loan from Cheval (the “Bridge
Loan”), and (b) a loan or loans from Nomis (the “Claims Advances Loan(s)”).


 


1.10        Cheval
is willing to provide the Bridge Loan and Nomis is willing to provide the Claims Advances Loans, subject to the express requirements
of this Agreement, including without limitation the preferred priority in Collateral granted to the Bridge Loan and the Claims
Advances Loans pursuant to the terms of this Agreement. Additionally, Cheval, Nomis and Borrower desire to have the Bridge Loan
and the Claims Advances Loans treated as advances pursuant to the Term Loan. The other Lenders and Agent are willing to agree
to the preferred priority in Collateral and treatment of the Bridge Loan and the Claims Advances Loans as advances pursuant to
the Term Loan, subject to the express requirements of this Agreement.


 


Section
2. FORBEARANCE


 


2.1          So
long as no Event of Default (other than the Existing Defaults) shall occur on or after the date hereof under any of Section 9.1(d),
(e), (f), (h), (i), (j), (k), (l) or (n) of the Credit Agreement (any such occurrence, a “Forbearance Default”),
and otherwise subject to and upon all the terms and conditions set forth herein, Agent and Lenders agree that during the Forbearance
Period, except as otherwise set forth in Section 2.2, they shall refrain from exercising their default rights and remedies in
connection with the Existing Defaults. Notwithstanding the preceding grant of forbearance with respect to the Existing Defaults,
Borrower understands, acknowledges and agrees that: (i) neither Agent nor any Lender has waived the Existing Defaults; and (ii)
the Term Loan is not hereby reinstated or extended and will remain in default throughout the Forbearance Period. For the avoidance
of doubt, the Forbearance Period will expire automatically and without notice immediately upon the occurrence of any Forbearance
Default.


 






    3 


     


    

 


2.2          The
preceding grant of forbearance with respect to the Existing Defaults shall not apply to the right of Agent and Lenders to assess
interest on the Term Loan and the Note at the Default Interest Rate. Borrower acknowledges that interest shall accrue at the Default
Interest Rate on the Term Loan and the Note at all times after December 1, 2017 until the Term Loan is paid in full.


 


Section
3. MODIFICATION OF TERM LOAN AND CREDIT AGREEMENT


 


3.1          Modification
of Term Loan. The Term Loan is hereby modified to include the additional loans provided for below, each of which shall be
deemed to be part of the Term Loan and shall be subject to all of the terms and conditions of this Agreement and the Credit Agreement
that are applicable to the Term Loan:


 


(a)          Bridge
Loan. Cheval, severally, and not jointly with the other Lenders, agrees to advance to Borrower the Bridge Loan in the principal
amount of $1,500,000.00. The Bridge Loan shall be made in a single advance and shall be evidenced by a new promissory note in
substantially the form attached hereto as Exhibit A (the “Bridge Note”). The Bridge Loan shall be one
of the Obligations of Borrower under the Credit Agreement. Borrower acknowledges that the Bridge Note is issued under the Term
Loan and, therefore, (i) shall be immediately due and payable, subject to the agreement of the Agent and Lenders to forbear during
the Forbearance Period, and (ii) shall accrue interest at the Default Interest Rate at all times until paid in full.


 


(b)          Claims
Advances Loans. Nomis, severally, and not jointly with the other Lenders, agrees, on an uncommitted basis and in its sole
discretion, to advance to Borrower from time to time Claims Advances Loans. The Claims Advances Loans may be advanced directly
to the Borrower or to designees of the Borrower (including without limitation the Designated Lawyers (as defined below) or the
Benz Entity (as defined below)) but shall in any case be Obligations of the Borrower under the Credit Agreement. Notwithstanding
anything to the contrary contained in the Credit Agreement, including Section 4.7 thereof, proceeds of the Claims Advances Loans
shall be used solely to investigate the Benz Claims (as defined below) or in furtherance or settlement discussions with Savant
(as defined below) or in payment of the Designated Lawyers (as defined below). The Claims Advances Loans may consist of multiple
advances (and such advances may be made to Borrower or to third parties at the direction of Borrower) and shall be evidenced by
a new promissory note in substantially the form attached hereto as Exhibit B (the “Claims Advances Note”).
Borrower acknowledges that the Claims Advances Note is issued under the Term Loan and, therefore, (i) shall be immediately due
and payable, subject to the agreement of the Agent and Lenders to forbear during the Forbearance Period, and (ii) shall accrue
interest at the Default Interest Rate at all times until paid in full.


 


3.2          Reserved.


 


3.3          Modification

(b)          The

Loan, the Grid Loan, the Bridge Loan and the Claims Advances Loans, with each loan issued under such facility evidenced by one
or more promissory notes, including, without limitation, the Original Term Loan Notes, the Additional Term Loan Notes, the Grid

10.9     Collateral Matters. Lenders irrevocably authorize Agent, at its option and in its discretion, to release any Lien
granted to or held by Agent under this Agreement or any Security Document (i) upon the payment in full of all Obligations or (ii)
constituting property sold or disposed of as part of or in connection with any disposition permitted under the Settlement Agreement
(it being understood and agreed that Agent may conclusively rely without further inquiry on a certificate of a Responsible Officer
as to the sale or other disposition of property being made in full compliance with the provisions of the Settlement Agreement).
Upon request by Agent at any time, Lenders will confirm Agent’s authority to release particular types or items of Collateral
pursuant to this Section 10.9.”


 


Section
5. OTHER MODIFICATIONS, RATIFICATIONS AND AGREEMENTS.


 


5.1          This
Agreement constitutes one of the Financing Documents. All references in the Financing Documents to any terms or provisions of
the Credit Agreement, the Financing Documents or the Obligations modified by this Agreement are hereby modified to refer to those
terms and provisions as modified by this Agreement. All references in each Financing Document to any other Financing Documents
are hereby modified to refer to such Financing Documents as modified by this Agreement.


 


5.2          Borrower
acknowledges that the indebtedness evidenced by the Note is just and owing, that the balance thereof is correctly shown in the
records of Agent and each Lender as of the date hereof, and Borrower agrees to pay the indebtedness evidenced by the Note and
the indebtedness secured by the Financing Documents, according to the terms thereof, subject only to the express agreements regarding
forbearance provided for herein.


 


5.3          Borrower
hereby reaffirms to Agent and each Lender each of the representations, warranties, covenants and agreements of Borrower set forth
in the Note, the Credit Agreement and all other Financing Documents, with the same force and effect as if each were separately
stated herein and made as of the date hereof.


 


5.4          Borrower
hereby ratifies, reaffirms, acknowledges, and agrees that the Note, the Credit Agreement and the other Financing Documents represent
valid, enforceable and collectible obligations of Borrower, and that there are no existing claims, defenses, personal or otherwise,
or rights of setoff whatsoever with respect to any of these documents or instruments.

5.5          Borrower
hereby expressly waives, releases and absolutely and forever discharges Agent and each Lender and, with respect to each of the
foregoing, its present and former shareholders, directors, officers, members, managers, employees and agents, and their separate
and respective heirs, personal representatives, successors and assigns, from any and all liabilities, claims, demands, damages,
action and causes of action, whether known or unknown and whether contingent or matured, that Borrower may now have, or has had
prior to the date hereof, or that may hereafter arise with respect to acts, omissions or events occurring prior to the date hereof
and, without limiting the generality of the foregoing, from any and all liabilities, claims, demands, damages, actions and causes
of action, known or unknown, contingent or matured, arising out of, or in any way connected with, the Obligations and the Financing
Documents.


 


5.6          All
terms, conditions and provisions of the Note, the Credit Agreement and the other Financing Documents are continued in full force
and effect and shall remain unaffected and unchanged, except as otherwise expressly provided in this Agreement.


 


5.7          This
Agreement in no way acts as a release or relinquishment of those liens, security interests and rights securing payment of the
Obligations. Such liens, security interests and rights are hereby ratified, confirmed, renewed and extended by Borrower in all
respects.


 


5.8          The
agreements contained herein shall not be binding upon Agent or any Lender until this Agreement has been fully executed by all
parties.

shall execute and deliver such additional documents and do such other acts as Lender may reasonably require to fully implement
the intent of this Agreement.


 


6.2          Borrower
hereby authorizes Agent to file, and Agent hereby agrees to file, appropriate UCC financing statement amendments in the appropriate
jurisdictions relating to the Liens granted to Agent and Lenders under the Credit Agreement, which describe with sufficient specificity

6.3          Each
Party shall pay all of its own costs and expenses, including, but not limited to, reasonable attorneys’ fees incurred in
connection with the preparation and negotiation of this Agreement.


 


6.4          No
express or implied consent to any further modifications involving any of the matters set forth in this Agreement or to any modifications
of the Financing Documents shall be inferred or implied by Agent or any Lender’s execution of this Agreement. Further, Agent
and Lenders’ execution of this Agreement shall not constitute a waiver (either express or implied) of the requirement that
any further modification of this Agreement, the Note, the Credit Agreement or any other Financing Documents shall require the
express written approval of Agent and each Lender; no such approval (either express or implied) has been given as of the date
hereof.


 


6.5          Notwithstanding
this or any prior forbearance, actual or implied, of any nature by Agent or any Lender, including but not limited to any acceptance
of late payments, time is hereby declared to be of the essence hereof, and (except as expressly provided otherwise in this Agreement)
of the Obligations, the Note, the Credit Agreement and all of the other Financing Documents. Each of Agent and Lenders require,
and Borrower agrees to, strict performance of each and every covenant, condition, provision and agreement hereof, and (except
as expressly provided otherwise in this Agreement) of the Obligations, the Note, the Credit Agreement and all of the other Financing
Documents.
