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.

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.
