The Old Notes were issued pursuant to that certain Indenture (the “2018 Indenture”) and First Supplemental Indenture (collectively, the “Existing Indenture”), each dated as of October 17, 2018, between the Company, as issuer, and Wilmington Trust, National Association, as trustee (in such capacity, the “Trustee”).  The New Notes will be issued pursuant to the 2018 Indenture and a Second Supplemental Indenture dated as of the Closing Date (as defined below) (collectively, the “Indenture”) between the Company, as issuer, and the Trustee, substantially in the forms set forth as Exhibit D hereto.  

The Investor understands that the Exchange is being made without registration under the Securities Act of 1933, as amended (the “Securities Act”), or any securities laws of any state of the United States or of any other jurisdiction, and that the New Notes are only being offered to “qualified institutional buyers” (as defined in Rule 144A under the Securities Act), and the Company hereby confirms that the offer and sale of the New Notes are exempt from registration under the Securities Act.

1.Agreement to Exchange.  Subject to the terms and conditions of this Exchange Agreement, the Investor hereby agrees to exchange an aggregate principal amount of the Old Notes set forth on Exhibit A hereto for the New Notes.

The Exchange will occur in accordance with the procedures set forth in Section 3 hereof.

0.Xxxxxxxx.  Subject to the terms and conditions of this Exchange Agreement, the Investor hereby sells, assigns and transfers to, or upon the order of, the Company, all right, title and interest in such portion of the Old Notes as indicated on Exhibit A hereto, waives any and all other rights with respect to such Old Notes and the Existing Indenture and releases and discharges the Company from any and all claims the Investor and the Accounts may now have, or may have in the future, arising out of, or related to, such Old Notes, including, without limitation, any claims arising from any existing or past defaults under the Existing Indenture, or any claims that the Investor is entitled to receive additional interest with respect to the Old Notes.

At or prior to 9:30 a.m., New York City time, on the Closing Date, the Investor agrees to direct the eligible participant of The Depository Trust Company (“DTC”) through which it holds a beneficial interest in the Old Notes to submit a withdrawal instruction through DTC’s Deposits and Withdrawal at Custodian (“DWAC”) program to the Trustee), for the aggregate principal amount of the Old Notes to be exchanged pursuant to this Exchange Agreement (the “DWAC Withdrawal”).

DTC will act as securities depositary for the New Notes.  At or prior to 9:30 a.m. New York City time on the Closing Date, the Investor agrees to direct an eligible DTC participant to submit a deposit instruction (the “New Notes DWAC Deposit”) through DTC’s DWAC program to the Trustee, for the aggregate principal amount of New Notes that it is entitled to receive pursuant to this Exchange Agreement, or comply with such other settlement procedures mutually agreed in writing by the Investor and the Company.  The New Notes will not be delivered until a valid DWAC Withdrawal of the Old Notes has been received and accepted by the Trustee.  If the Closing does not occur, any Old Notes submitted for DWAC Withdrawal will be returned to the DTC participant that submitted the withdrawal instruction in accordance with the procedures of DTC.  The Investor acknowledges that each of the DWAC Withdrawal and the New Notes DWAC Deposit must be posted on the Closing Date and that if it is posted before the Closing Date, then it will expire unaccepted and must be resubmitted on the Closing Date.

For the convenience of the Investor, attached hereto as Exhibit B is a summary of the delivery instructions that must be followed to settle the Exchange through DTC.

On the Closing Date, subject to satisfaction of the conditions precedent specified in this Exchange Agreement, and the prior receipt of a valid DWAC Withdrawal conforming with the aggregate principal amount of the Old Notes to be exchanged by the Investor and a valid New Notes DWAC Deposit conforming with the aggregate principal amount of the New Notes to be issued to the Investor in the Exchange, the Company hereby agrees to execute such New Notes, and direct the Trustee to authenticate and, by acceptance of the New Notes DWAC Deposit, deliver, such New Notes (or comply with such other settlement procedures mutually agreed in writing by the Company and the Trustee), in each case to the DTC account specified on Exhibit A to this Exchange Agreement.

If (x) the Trustee is unable to locate the DWAC Withdrawal or (y) the Trustee is unable to locate the New Notes DWAC Deposit or (z) such DWAC Withdrawal does not conform to the Old Notes to be exchanged in the Exchange or such New Notes DWAC Deposit does not conform to the New Notes to be issued in the Exchange, then the Company will promptly notify the Investor.  If, because of the occurrence of an event described in clause (x), (y) or (z) of the preceding

​

sentence, the New Notes are not delivered on the Closing Date, then such New Notes will be paid or delivered, as applicable, on the first business day following the Closing Date (or as soon as reasonably practicable thereafter) on which all applicable conditions set forth in clauses (x), (y) or (z) of the first sentence of this paragraph have been cured.

All questions as to the form of all documents and the validity and acceptance of the Old Notes will be determined by the Company, in its reasonable discretion, which determination will be final and binding.

All authority herein conferred or agreed to be conferred in this Exchange Agreement will survive the dissolution of the Investor, and any representation, warranty, undertaking and obligation of the Investor hereunder will be binding upon the trustees in bankruptcy, legal representatives, successors and assigns of the Investor.

(f)No consent, approval, authorization, order, license, registration or qualification of or with any court or governmental or regulatory authority is required for the execution, delivery and performance by the Company of its obligations under this Exchange Agreement, the Indenture and the New Notes and the consummation of the transactions contemplated by this Exchange Agreement, the Indenture and the New Notes, except such as have been obtained or made (or will, at the Closing, have been obtained or made) by the Company.

Under U.S. federal income tax law, a holder who exchanges Old Notes for the New Notes generally must provide such holder’s correct taxpayer identification number (“TIN”) on IRS Form W-9 (attached hereto) or otherwise establish a basis for exemption from backup withholding.  A TIN is generally an individual holder’s social security number or a holder’s employer identification number.  If the correct TIN is not provided, the holder may be subject to a $50 penalty imposed by the IRS.  In addition, certain payments made to holders may be subject to U.S. backup withholding tax (currently set at 24% of the payment).  If a holder is required to provide a TIN but does not have the TIN, the holder should consult its tax advisor regarding how to obtain a TIN.  Certain holders are not subject to these backup withholding and reporting requirements.  Non-U.S. Holders generally may establish their status as exempt recipients from backup withholding by submitting a properly completed applicable IRS Form W-8 (available from the Company or the IRS at xxx.xxx.xxx), signed, under penalties of perjury, attesting to such holder’s exempt foreign status.  U.S. backup withholding is not an additional tax.  Rather, the U.S. federal income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld.  If withholding results in an overpayment of taxes, a refund may be obtained provided that the required information is timely furnished to the IRS.  Holders are urged to consult their tax advisors regarding how to complete the appropriate forms and to determine whether they are exempt from backup withholding or other withholding taxes.
