FOR VALUE RECEIVED, the Issuer promises to pay to Lumos Debt Holdings, L.P., a Delaware limited partnership, or a Transferee (together with its successors and Transferees, the “Holder”), the aggregate principal sum of one hundred fifty million dollars ($150,000,000) on the Maturity Date and to pay interest (each, an “Interest Payment”) on the principal sum outstanding from time to time under this Note. Interest on this Note will accrue at the rate per annum equal to 8.0% and will be due and payable in cash in immediately available funds in arrears on a quarterly basis on August 15, November 15, February 15 and May 15 during the term of this Note (each an “Interest Payment Date”), commencing on November 15, 2015; provided that at the election of the Issuer any interest accrued can be paid (a “PIK Payment”) through the issuance of additional notes or by adding such accrued amounts to the unpaid principal amount of the Note outstanding at such time (“PIK Interest”). Any failure by the Issuer to pay interest in cash on any Interest Payment Date shall be deemed to be an election to make a PIK Payment of such interest by adding such interest to the unpaid principal amount of the Note outstanding at such time.

Any additional Note issued will be dated as of the applicable interest payment date and will bear interest from and after such date. For purposes of this Note, all references to “principal amount” of the Notes shall include any increase in the principal amount of the Notes as a result of a PIK Payment.

Interest will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from and including the original issue date of this Note. Interest will be computed on the basis of a 360-day year of twelve 30-day months. Interest Payments will be paid to the Person in whose name this Note is registered on the Notes Register on the Business Day prior to the applicable payment date.

The Issuer agrees to pay all reasonable expenses, including reasonable attorneys’ fees, which may be incurred by the Holder in connection with any waiver or consent hereunder, any amendment hereof, any Event of Default hereunder or in successfully enforcing the provisions of this Note and/or successfully collecting any amount due under this Note.

DEFAULTS AND REMEDIES

Section 10.01 Events of Default. Each of the following shall constitute an “Event of Default”:

(a) any default by the Issuer in (i) the payment of any principal on this Note when the same becomes due and payable at the Maturity Date, upon acceleration or otherwise, and such default continuing for a period of two (2) Business Days or (ii) the making of any payment required to be made under Section 4.02;

(b) the Issuer fails to comply with Article 6 as and when required and such failure continues for thirty (30) days after the receipt of notice described below;

(c) the Issuer, or any Subsidiary, fails to pay any Indebtedness within any applicable grace period provided in such Indebtedness after final maturity or the acceleration of any such Indebtedness by the holders thereof because of a default if the total amount of such Indebtedness unpaid or accelerated exceeds the Threshold Amount or its foreign currency equivalent at the time;

(d) the Issuer, or any Material Subsidiary or any group of Subsidiaries of the Issuer that, taken together, would constitute a Material Subsidiary, makes an assignment for the benefit of creditors generally, files a petition in bankruptcy, is adjudicated insolvent or has entered against it an order for relief under Bankruptcy Laws, petitions or applies to any tribunal for any receiver or trustee (for itself or its assets in connection with the bankruptcy, insolvency, or in the case of the Issuer only, the liquidation of such Person ), commences any proceeding relating to itself under any bankruptcy, reorganization, readjustment of debt law or statute of any jurisdiction, has commenced against it involuntarily any such proceeding (provided such involuntary proceeding remains undismissed for the earlier of a period of 60 days or until an order for relief is entered), or indicates its consent to, approval of or acquiescence in any such proceeding, or any receiver of or trustee for the Issuer or any of its Subsidiaries or any substantial part of their property is appointed; or

(e) any judgments or orders, either individually or in the aggregate, for the payment of money in excess of the Threshold Amount shall be rendered against the Issuer or any Material Subsidiary or any group of Subsidiaries of the Issuer that, taken together, would constitute a Material Subsidiary, and there shall be any period of 45 consecutive days during which a stay of enforcement of such judgment or order, by reason of a pending appeal or otherwise, shall not be in effect; provided, however, that any such judgment or order shall not

14

give rise to an Event of Default under this Section 10.01(e) if and for so long as (i) the amount of such judgment or order is covered by a valid and binding policy of insurance between the defendant and the insurer, which shall be rated at least “A” by A.M. Best Company, covering full payment thereof and (ii) such insurer has been notified, and has not disputed the claim made for payment of, the amount of such judgment or order.

The Issuer shall deliver to the Holder, within five (5) Business Days after its knowledge of the occurrence thereof, written notice in the form of an Officer’s Certificate of any Event of Default and any event which with the giving of notice or the lapse of time would become an Event of Default and what action the Issuer is taking or proposes to take with respect thereto.

Section 10.02 Acceleration. If an Event of Default (other than an Event of Default specified in Section 10.01(d)) occurs and is continuing, the Required Noteholders, by notice to the Issuer, may declare the outstanding principal amount of and accrued but unpaid interest on the Notes to be due and payable. Upon such a declaration, such outstanding principal amount and interest shall be due and payable immediately. If an Event of Default specified in Section 10.01(d) occurs and is continuing, the outstanding principal amount of, and accrued interest on, all the Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of any Noteholder.

The Required Noteholders may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

A delay or omission by the Holder or any other Noteholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are, to the extent permitted by law, cumulative.

Section 10.03 Waiver of Past Defaults. The Required Noteholders may waive any past or existing Default and its consequences except (i) a Default in the payment of the outstanding principal amount of or interest on the Notes or (ii) a Default in respect of a provision that under Section 10.04 or Article 12 cannot be amended without the consent of each Noteholder affected. When a Default is waived, it is deemed cured, and any Event of Default arising therefrom shall be deemed to have been cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

Section 10.04 Rights of Holder to Receive Payment. Notwithstanding any other provision of this Note, the right of the Holder to receive payment of the outstanding principal amount of and interest on this Note on or after the respective due dates expressed in this Note, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of the Holder.

Section 10.05 Waiver of Stay or Extension Laws. The Issuer (to the extent it may lawfully do so) shall not at any time insist upon, or plead, or in any manner whatsoever claim or

15

take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Note, and the Issuer (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Holder, but shall suffer and permit the execution of every such power as though no such law had been enacted.

SAVINGS CLAUSE

In case any provision of this Note is held by a court of competent jurisdiction to be excessive in scope or otherwise invalid or unenforceable, such provision shall be adjusted rather than voided, if possible, so that it is enforceable to the maximum extent possible, and the validity and enforceability of the remaining provisions of this Note will not in any way be affected or impaired thereby.

ENTIRE AGREEMENT; AMENDMENTS

This Note constitutes the full and entire understanding and agreement between the Issuer and the Holder with respect to the subject hereof. Except as otherwise provided in Section 10.03, neither this Note nor any term hereof may be amended, waived, discharged or terminated other than by a written instrument signed by the Issuer and the Required Noteholders; provided that any amendment (i) of the Maturity Date or (ii) with respect to the reduction of the outstanding principal amount or any interest rate or premium hereunder shall require, in each case, the written consent of each Noteholder affected.

After an amendment under this Article 12 becomes effective, the Issuer shall mail to the Noteholders a notice briefly describing such amendment. The failure to give such notice to all Noteholders, or any defect therein, shall not impair or affect the validity of an amendment under this Article 12.

TRANSFER; ASSIGNMENT, ETC.

In connection with any transfer, if the Issuer reasonably requests, the transferor shall deliver a representation in writing that such transfer is pursuant to an effective registration statement under the Securities Act of 1933, as amended, or pursuant to an available exemption from, or in a transaction not subject to, registration under the Securities Act of 1933, as amended. The Issuer agrees that in connection with any transfer, assignment, pledge or encumbrance permitted pursuant to the terms hereof, the

16

Issuer shall cause such transfer, assignment, pledge or encumbrance to be reflected in the Notes Register, and all principal, interest and other amounts which are then, and thereafter become, due under this Note shall be paid to such Transferee at the place of payment designated in such notice. The Issuer may not assign this Note or any of its rights or obligations hereunder. This Note shall be binding upon the Issuer and its respective successors and shall inure to the benefit of the Holder and its successors and permitted assigns.

NO WAIVER

No failure on the part of the Holder to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by the Holder of any right, remedy or power hereunder preclude any other or future exercise of any other right, remedy or power. Each and every right, remedy or power hereby granted to the Holder or allowed it by law or other agreement shall be cumulative and not exclusive of any other, and may be exercised by the Holder from time to time.
