 By execution and delivery of this Agreement, we
hereby agree as follows:

Upon the terms and subject to the conditions set forth in the Term Sheet and such other terms and conditions to be provided in the
Exchange and Tender Offer and the documents related thereto, which shall be, in each case, consistent with the Term Sheet, in consideration of the promises and mutual covenants and agreements herein contained, the holder named on the signature pages
hereto (the “Holder”) hereby agrees to tender, and will cause its affiliates to tender, pursuant to the Exchange and Tender Offer, and not withdraw or revoke such tender unless the conditions set forth in Section 2 are not
satisfied or this Agreement is terminated pursuant to Section 8 hereof, the aggregate principal amount of Notes set forth under the Holder’s name on the signature pages hereto (the “Initial Notes” and, together with any
additional Notes held by the Holder or such controlled affiliates, the “Holder’s Notes”) in the Exchange and Tender Offer as soon as practicable following the commencement of the Exchange and Tender Offer but no later than 5:00

 2. Conditions. The Holder’s obligations under Section 1 of this Agreement
and the Company’s acceptance of any Notes tendered by the Holder (or a controlled affiliate) shall be subject to consummation of the Exchange and Tender Offer upon the terms and subject to the conditions set forth in the Term Sheet and in the
Exchange and Tender Offer (or waiver or modification of any such conditions by the Company in its sole discretion, provided that any such waiver or modification, whether singularly or in the aggregate, will not materially adversely affect the Holder
without the Holder’s prior written consent, such consent not to be unreasonably withheld, conditioned or delayed). The Holder acknowledges that any amendment, extension or other modification to the expiration deadline (to the extent required by
any relevant regulatory review process) shall not be deemed to materially adversely affect the Holder for purposes of this Section 2 and Sections 5(a)(ii), 5(f) and 8(d) of this Agreement. The Holder acknowledges that the Company’s
acceptance of any Notes tendered will, among other things, be subject to raising sufficient cash in the Rights Offering to accept all or part of the Notes tendered for cash.

(b) Prior to the Termination Date and subject to the terms and conditions of this Agreement, the Holder agrees not to, and will cause its

disclose the name of the Holder or amount of the Holder’s Notes held by the Holder (or its affiliates) or that the Holder has entered into this Agreement in any public manner, including in the Exchange and Tender Offer or any related press
release;

provided, however, that (i) the Company may disclose such name or amount to the extent that it is required to do so by the Securities and Exchange Commission, the Nasdaq

governing the New Notes, Exchange and Tender Offer and Rights Offering and such other documents relating thereto as the Holder may reasonably request in advance of the commencement. The Company agrees that the Indenture shall be consistent with the
Term Sheet and contain other customary terms for publicly traded senior secured second liens notes and the Exchange and Tender Offer and Rights Offering will be consistent with the Term Sheet and contain such other terms and conditions as are
customary. Until the commencement of the Exchange and Tender Offer (or the termination hereof), the Holder agrees to treat as confidential any information in such drafts which is not public information. 

(f) The Company agrees to allow the Holder to withdraw such Holder’s tender in the Exchange and Tender Offer (if such Holder so
chooses) if the Company changes any term or condition from those in the Term Sheet or in the Exchange and Tender Offer or Rights Offering reviewed by the Holder that materially adversely affects the Holder without the Holder’s prior written
consent, such consent not to be unreasonably withheld, conditioned or delayed, as more fully set forth herein.
