Terms defined in the preamble or recitals hereto are used herein as therein defined Section 1.02. References in this Supplemental Indenture to article and section numbers shall be deemed to be references to article and section numbers of this Supplemental Indenture unless otherwise specified. ARTICLE 2 GUARANTEE Section 2.01. Agreement to Guarantee.

(b) The obligations of Scripps are limited to the maximum amount, as will, after giving effect to all other contingent and fixed liabilities of Scripps and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its subsidiary guarantee or pursuant to its contribution obligations under the Indenture, result in the obligations of Scripps under the subsidiary guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law, or being void or unenforceable under any law relating to insolvency of debtors. (c) The subsidiary guarantee will be a continuing guarantee and shall (i) remain in full force and effect until payment in full of the principal amount of all outstanding Notes (whether by payment at maturity, purchase, redemption, defeasance, retirement or other acquisition) and all other subsidiary guaranteed obligations of Scripps then due and owing unless earlier terminated as described below, (ii) be binding upon Scripps and (iii) inure to the benefit of and be enforceable by the Trustee, the Holders and their permitted successors, transferees and assigns. 5

Notwithstanding the foregoing provisions of this Section 2.01, Scripps will automatically and unconditionally be released from all obligations under its subsidiary guarantee, and the subsidiary guarantee shall thereupon terminate and be discharged and of no further force or effect, (i) concurrently with any direct or indirect sale or disposition (by merger or otherwise) of Scripps or any interest therein, or any other transaction, in accordance with the terms of the Indenture, (ii) at any time that Scripps is (or, substantially concurrently with the release of the subsidiary guarantee or if as a result of the release of the subsidiary guarantee, will be) released from all of its obligations under its guarantee of payment by the Company of any Debt of the Company or the Guarantor under the Revolving Credit Facility (it being understood that a release subject to contingent reinstatement is still a release, and that if any such guarantee is so reinstated, such subsidiary guarantee shall also be reinstated to the extent that Scripps would then be required to provide a subsidiary guarantee pursuant to this Section 2.01), (iii) upon the merger or consolidation of Scripps with and into the Company or the Guarantor or another Subsidiary Guarantor that is the surviving person in such merger or consolidation, or upon the liquidation of Scripps following the transfer of all of its assets to the Company or the Guarantor or another Subsidiary Guarantor, (iv) concurrently with Scripps ceasing to constitute a Domestic Subsidiary of the Guarantor, (v) upon legal or covenant defeasance of the Company’s obligations, or satisfaction and discharge of the Notes, or (vi) upon payment in full of the aggregate principal amount of all Notes then outstanding and all other subsidiary guaranteed obligations then due and owing (provided that the obligations of Scripps hereunder shall be reinstated if at any time any payment which would otherwise have reduced or terminated the obligations of Scripps hereunder and under its subsidiary guarantee (whether such payment shall have been made by or on behalf of the Company or by or on behalf of Scripps) is rescinded or reclaimed from any of the Holders upon the insolvency, bankruptcy, liquidation or reorganization of the Company or Scripps or otherwise, all as though such payment had not been made).
