7. Netting Rights.

(a) Securities Contract. The Company and the Investor hereby acknowledge and agree that the Amendment and Exchange Agreement, the Securities Purchase Agreement and the Note Purchase Agreement each is a “securities contract” as defined in 11 U.S.C. § 741 and that Investor shall have all rights in respect of the Investor Note, the New Series B Note, the Amendment and Exchange Agreement, the Amended Master Netting Agreement (as defined in the Amendment and Exchange Agreement), the Securities Purchase Agreement and the Note Purchase Agreement as are set forth in 11 U.S.C. § 555 and 11 U.S.C. § 362(b)(6), including, without limitation, all rights of credit, deduction, setoff, offset, recoupment, and netting (collectively, “Netting” or “Net”) as are available under this Note, the New Series B Note and the Amended Master Netting Agreement.

(b) Investor Optional Netting. Notwithstanding anything herein to the contrary, the Investor may, (I) at any time on or after the occurrence of an Event of Default or a Change of Control (in each case, whether or not a Redemption Notice has been delivered by the Investor to the Company with respect thereto) or, (II) after August 13, 2018, at its option and at its sole discretion, by written notice to the Company, Net, in whole or in part, any Permitted Amount (as defined in the Amended Master Netting Agreement) of any Unpaid Amount (as defined in the Amended Master Netting Agreement) owed by the Investor to the Company under this Note or any other Underlying Agreement (as defined in the Amended Master Netting Agreement) against (across or within each or all of the Underlying Agreements) (x) any Unpaid Amounts owed by the Company to the Investor under the New Series B Notes or (y) any Unpaid Amounts (subject to the limitations contained in the Amended Master Netting Agreement regarding an Equity Conditions Failure) owed by the Company to the Investor under any other Underlying Agreement, as set forth in such written notice (each, an “Investor Optional Netting”); provided, that no Investor Optional Netting shall occur hereunder with respect to any Mandatory Prepayment Amount that the Investor fails to properly prepay hereunder in violation of this Note. Upon any Investor Optional Netting, (x) such portion of Principal subject to such Investor Optional Netting shall be deemed surrendered and concurrently cancelled as of the date of such Investor Optional Netting and (y) any accrued and unpaid Interest hereunder with respect to such portion of Principal subject to such Investor Optional Netting shall be automatically cancelled as of the date of such Investor Optional Netting. Each Investor Optional Netting shall be effective upon the date the Investor delivers written notice to the Company of the Investor’s election to effect such Investor Optional Netting.

(c) Automatic Netting at Redemption Date. Notwithstanding anything herein to the contrary, on each Redemption Date, solely to the extent such portion of the Conversion Amount subject to redemption includes Restricted Principal (such aggregate amount of Restricted Principal subject to the applicable redemption on the such Redemption Date, each, a “Redemption Restricted Amount”), the Investor shall automatically Net (each, a “Redemption Netting”) such part of the outstanding obligations under the New Series B Note equal to such Redemption Restricted Amount by the cancellation of the Redemption Restricted Amount of the outstanding obligations under the New Series B Note in exchange for the surrender and concurrent cancellation of such portion of this Note with an amount of aggregate Principal then outstanding hereunder equal to such Redemption Restricted Amount (each a “Redemption Netting Principal Amount”).

Each Redemption Netting shall automatically occur on the applicable Redemption Date. For the avoidance of doubt, if prior to the applicable Redemption Date all, or any portion, of a Redemption Restricted Amount is converted (whether by Acceleration or otherwise in accordance with the terms of the New Series B Note) or such other event occurs whereafter such portion of the Redemption Restricted Amount is not required to be redeemed on the Redemption Date in accordance with the terms of the New Series B Note (as amended, modified or waived on or prior to such date)(each a “Reversed Redemption Restricted Amount”), solely with respect to such Redemption Date, no Redemption Netting shall occur with respect to such Reversed Redemption Restricted Amount.

(d) Automatic Netting at Maturity. Notwithstanding anything herein to the contrary, at the Scheduled New Series B Note Maturity Date, if any amounts remain outstanding under the New Series B Note and hereunder, the Investor shall automatically Net such part of the outstanding obligations under the New Series B Note equal to the aggregate Principal then outstanding hereunder (the “Remaining Principal Amount”) by the cancellation of the Remaining Principal Amount of the outstanding obligations under the New Series B Note in exchange for the surrender and concurrent cancellation of the aggregate Principal then outstanding hereunder (the “Maturity Netting”). Upon any Maturity Netting, any accrued and unpaid Interest hereunder with respect to such portion of Principal being cancelled in such Maturity Netting shall be automatically cancelled as of the date of such Maturity Netting and, thereafter, this Note shall be deemed to be paid in full and shall be null and void. The Maturity Netting shall automatically occur on the Scheduled New Series B Note Maturity Date.

(e) Event of Default Netting. Notwithstanding anything herein to the contrary, Investor may, at any time on or after the occurrence of any Event of Default under the New Series B Note, but prior to the related Event of Default Right Expiration Date, at its sole discretion, by written notice to the Company, Net all, or any part, of the outstanding obligations under the New Series B Note by the cancellation of such portion of the outstanding obligations under the New Series B Note as set forth in such written notice in exchange for the surrender and concurrent cancellation of an equal amount of Principal hereunder (each, an “Event of Default Netting”). Upon any Event of Default Netting, any accrued and unpaid Interest hereunder with respect to such portion of Principal being satisfied in such Event of Default Netting shall be automatically cancelled as of the date of such Event of Default Netting. Each Event of Default Netting shall be effective upon the date the Investor delivers notice to the Company of the Investor’s election to effect such Event of Default Netting.

(f) Automatic Netting Upon any Bankruptcy Event of Default. Notwithstanding anything herein to the contrary, upon any Bankruptcy Event of Default under the New Series B Note, the Investor shall automatically Net such part of the outstanding obligations under the New Series B Note equal to the Remaining Principal Amount by the cancellation of the Remaining Principal Amount of the outstanding obligations under the New Series B Note in exchange for the surrender and concurrent cancellation of the aggregate Principal then outstanding hereunder (each, a “Bankruptcy Event of Default Netting”, and together with the Investor Optional Netting, Redemption Netting, Maturity Netting and Event of Default Netting, collectively, the “Investor Netting Rights”). Upon any Bankruptcy Event of Default Netting, any accrued and unpaid Interest hereunder with respect to such portion of Principal being satisfied in such Bankruptcy Event of Default Netting shall be automatically cancelled as of the date of such Bankruptcy Event of Default Netting and, thereafter, this Note shall be deemed to be paid in full and shall be null and void. Each Bankruptcy Event of Default Netting shall be effective upon the date of the earliest occurrence of a Bankruptcy Event under the New Series B Note.

(g) Automatic Netting Upon Prohibited Transfers of this Note. If for any reason, this Note or any interest herein is pledged, assigned or transferred to any Person other than the Company without the prior written consent of the Investor, whether by contract, operation of law, court order or otherwise (each, a “Prohibited Transfer”), the Investor shall automatically Net such part of the outstanding obligations under the New Series B Note equal to 75% of the remaining Restricted Principal then outstanding under the New Series B Note (with the remaining 25% of the Restricted Principal of the New Series B Note automatically becoming unrestricted principal thereunder) in exchange for the surrender and concurrent cancellation of the aggregate Principal then outstanding hereunder. Upon any Prohibited Transfer, any accrued and unpaid Interest hereunder shall be automatically cancelled as of the date of such Prohibited Transfer and, thereafter, this Note shall be deemed to be paid in full and shall be null and void.
