But for the Waivers (as defined below) provided herein, Events of Default would exist under Section 11(c) of the Note Purchase Agreement as of March 31, 2016 and thereafter as a result of the Company’s failure to comply with Sections 10.1 and 10.2 of the Note Purchase Agreement for the Specified Quarters.

In consideration of the premises and for good and valuable consideration, the receipt and sufficiency of which are acknowledged, the Company and the undersigned Holders agree as follows:

2

comply with Sections 10.1 and 10.2 of the Note Purchase Agreement for each of the Specified Quarters (collectively, the “Waivers”), and agree that any failure by the Company to comply with such Sections 10.1 and/or 10.2 for the Specified Quarters shall not constitute a Default or an Event of Default until the Waiver Expiration Date.  Unless a further waiver is provided by the Holders pursuant to the Note Purchase Agreement, an immediate Event of Default shall occur under Section 11(c) of the Note Purchase Agreement on the Waiver Expiration Date, effective as of March 31, 2016.

(a)                                 Notice of Change of Control or Control Event — The Company will, within five Business Days after any Responsible Officer has knowledge of the occurrence of any Change of Control or Control Event, give notice of such Change of Control or Control Event to each holder of Notes; provided that, notwithstanding anything to the contrary in this Section 8.3, the Company shall not be required to give any notice of any Control Event unless and until it provides notice of such Control Event to the public (and public notice of such Control Event by filing of a Current Report on Form 8-K shall be deemed to constitute notice of such Control Event hereunder).  If a Change of Control has occurred, such notice shall contain and constitute an offer to prepay Notes as described in paragraph (b) of this Section 8.3 and shall be accompanied by the certificate described in paragraph (e) of this Section 8.3.

(b)                                 Offer to Prepay Notes — The offer to prepay Notes contemplated by paragraph (a) of this Section 8.3 shall be an offer to prepay, in accordance with and subject to this Section 8.3, all, but not less than all, of the Notes held by each holder (in this case only, “holder” in respect of any Note registered in the name of a nominee for a disclosed beneficial owner shall mean such beneficial owner) on a date specified in such offer (the “Proposed Prepayment Date”).  Such Proposed Prepayment Date shall be not less than 30 days and not more than 60 days after the date of such offer.

(c)                                  Acceptance; Rejection — A holder of Notes may accept or reject the offer to prepay made pursuant to this Section 8.3 by causing a notice of such acceptance or rejection to be delivered to the Company on or before the date specified in the certificate described in paragraph (e) of this Section 8.3.  A failure by a holder of Notes to respond to an offer to prepay made pursuant to this Section 8.3, or to accept an offer as to all of the Notes held by the holder, within such time period shall be deemed to constitute acceptance of such offer by such holder.

(d)                                 Prepayment — Prepayment of the Notes to be prepaid pursuant to this Section 8.3 shall be at 100% of the outstanding principal amount of such Notes, together with interest on such Notes accrued and unpaid to the date of prepayment, plus the Make-Whole Amount determined for such date of prepayment with respect to such principal amount.  The prepayment shall be made on the Proposed Prepayment Date.

(e)                                  Officer’s Certificate — Each offer to prepay the Notes pursuant to this Section 8.3 shall be accompanied by a certificate, executed by a Senior Financial Officer of the Company and dated the date of such offer, specifying: (i) the Proposed Prepayment Date, (ii) that such offer is made pursuant to this

4

Section 8.3, (iii) the principal amount of each Note offered to be prepaid, (iv) the interest that would be due on each Note offered to be prepaid, accrued to the Proposed Prepayment Date, (v) the estimated Make-Whole Amount that would be due on each Note offered to be prepaid (calculated as if the date of such offer were the date of the prepayment) and the details of such calculation, (vi) that the conditions of this Section 8.3 have been fulfilled, (vii) in reasonable detail, the nature and date or proposed date of the Change of Control and (viii) the date by which any holder of a Note that wishes to reject such offer must deliver notice thereof to the Company, which date shall not be earlier than seven Business Days prior to the Proposed Prepayment Date.

(f)                                   Make-Whole Amount Certificate — Two Business Days prior to the Proposed Prepayment Date, the Company will deliver to each holder of Notes (other than any holder who rejected the offer) a certificate, executed by a Senior Financial Officer of the Company, specifying the calculation of the Make-Whole Amount to be paid in respect of each Note as of the Proposed Prepayment Date.  In the event the Company incorrectly calculates the Make-Whole Amount payable with respect to any Note, the holder of such Note will not be bound by such incorrect calculation, but instead will be entitled to receive an amount equal to the correct Make-Whole Amount, calculated in compliance with the terms of this Agreement.”

2.3                               Section 8.5 of the Existing Note Purchase Agreement is hereby amended and restated in its entirety to read as follows:

“8.5                         Maturity; Surrender, etc.

In the case of each prepayment of Notes pursuant to this Section 8, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment, together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount, if any, and, in the case of the Sixth Waiver Prepayment, the Sixth Waiver Prepayment Premium.  From and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole Amount, if any, or Sixth Waiver Prepayment Premium, as aforesaid, interest on such principal amount shall cease to accrue.  Any Note paid or prepaid in full shall be surrendered to the Company and canceled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note.”
