Settlement of such purchase shall take place within 5 Business Days of the date of execution of this Purchase and Release Agreement (the “Agreement”) on a delivery-versus-payment basis upon CGMI’s crediting funds in the amount of the aggregate purchase price to Client’s Account and simultaneously debiting the Positions from Client’s Account. Notwithstanding the crediting of funds to Client’s Account, such aggregate purchase price in respect of all Positions shall be immediately applied to the repayment of all amounts that are (or upon demand or acceleration would be) payable in respect of Client’s Loan Obligations (as defined in the Loan) under the two Amended and Restated Loan Agreements dated as April 28, 2009, between CGMI and, respectively, WebMD Health Corp. and HLTH Corporation (the “Loans”) as of such settlement date and any balance of such aggregate purchase price remaining after such application will be available as a credit balance in Client’s Accounts (subject to any applicable margin, lending or lending-related or other agreements governing Client’s Accounts).

			Unless otherwise agreed by the parties, settlement of any purchase of Option Securities under this Section 1(b) shall take place not later than the 5th Business Day following CGMI’s receipt of the Exercise Notice with respect to the relevant Position on a delivery-versus-payment basis upon CGMI’s crediting the Option Securities corresponding to such Position to Client’s Settlement Account (as defined in Section 1(f)) and simultaneously debiting from Client’s Settlement Account the amount of the Exercise Price (as of such settlement date) for such Position, plus 100% of accrued unpaid interest through the settlement date (as determined by CGMI consistent with bond market practice) on the Option Securities corresponding to such Position; provided that it shall be a condition of CGMI’s obligation to make such delivery that sufficient funds are available in Client’s Settlement Account, and provided further that, to the extent any portion of the deliverable Option Securities constitutes

			As used herein, the term “Cash Redemption Amounts” means the amount of any cash actually received by CGMI in redemption of, or as a repayment of principal (including any payment on liquidation that discharges principal) on, or as payment received in respect of principal as a result of sale in a successful regularly-scheduled auction of, the Option Securities maintained pursuant to this Section 1(d).
	(e)		Removal — Notwithstanding the foregoing definitions of “Option Securities”, “Exercise Price” and “Cash Redemption Amounts”, CGMI may elect at any time to treat all or any portion of the Option Securities corresponding to a Position (the “Removed Portion”) as having been redeemed for cash at 100 percent of the outstanding principal amount thereof, in which event (i) the term “Option Securities” shall thereafter no longer include such Removed Portion, (ii) the amount of cash deemed to have been received in redemption of such Removed Portion shall be treated as a Cash Redemption Amount in connection with a Full Redemption, and (iii) CGMI shall notify Client that it has made such election and pay to Client the related Distributable Cash Redemption Amount within 10 Business Days.
	(f)		Maintenance of Settlement Account — Until the 20th calendar day following the Expiration Date, in the event that Client’s Accounts are closed or cease to be carried by CGMI, Client agrees to open and maintain a securities account at CGMI (“Client’s Settlement Account”) in the form and manner generally required by CGMI to effect the deliveries and payments contemplated under this Agreement.

Governing Law

This Agreement and all matters arising herein or in connection herewith will be governed by, and construed and enforced in accordance with, the law of the State of New York, including Section 5-1401 and Section 5-1402 of the General Obligations Law, but otherwise without reference to choice of law doctrine.

Arbitration

This Agreement contains a pre-dispute arbitration clause. By signing this Agreement, the parties agree as follows:

(a) All parties to this Agreement are giving up the right to ▇▇▇ each other in court, including the right to a trial by jury, except as provided by the rules of the arbitration forum in which a claim is filed.

(b) Arbitration awards are generally final and binding; a party’s ability to have a court reverse or modify an arbitration award is very limited.

(c) The ability of the parties to obtain documents, witness statements and other discovery is generally more limited in arbitration than in court proceedings.

(d) The arbitrators do not have to explain the reason(s) for their award.

(e) The panel of arbitrators will typically include a minority of arbitrators who were or are affiliated with the securities industry, unless Client is a member of the organization sponsoring the arbitration facility, in which case all arbitrators may be affiliated with the securities industry.

(f) The rules of some arbitration forums may impose time limits for bringing a claim in arbitration. In some cases, a claim that is ineligible for arbitration may be brought in court.

(g) The rules of the arbitration forum in which the claim is filed, and any amendments thereto, shall be incorporated into this agreement. The parties agree that any and all controversies that may arise between Client and CGMI out of or relating to the transactions contemplated hereby and any activity or claim related to the construction, performance, or breach of this Agreement shall be determined by arbitration conducted before FINRA Dispute Resolution (“FINRA-DR”) or, if

FINRA-DR declines to hear the matter, before the American Arbitration Association, in accordance with their arbitration rules then in force. The award of the arbitrator shall be final, and judgment upon the award rendered may be entered in any court, state or federal, having jurisdiction. No person shall bring a putative or certified class action to arbitration, nor seek to enforce any pre-dispute arbitration agreement against any person who has initiated in court a putative class action or who is a member of a putative class who has not opted out of the class with respect to any claims encompassed by the putative class action until: (i) the class certification is denied; (ii) the class is decertified; or (iii) the Client is excluded from the class by the court. Such forbearance to enforce an agreement to arbitrate shall not constitute a waiver of any rights under this Agreement except to the extent stated herein.

9.

Assignment

This Agreement may not be assigned by either Client or CGMI (each, a “Party”) without the consent of the other party, except that (i) Client may assign this Agreement to a wholly-owned U.S. subsidiary or a successor to Client by merger, consolidation or sale or other transfer of all or substantially all of Client’s assets and (ii) CGMI may assign this Agreement or its obligations hereunder to an affiliate or to a successor by merger, consolidation or sale or other transfer of all or substantially all of CGMI’s assets or to the extent it reasonably requires to effectively manage its assets and liabilities or its compliance with law or regulation in connection with any transfer, reorganization or outsourcing of its (or a portion of its) broker dealer operations, provided in each of cases (i) and (ii) such transferee shall agree to be bound by the transferor’s representations, warranties and obligations and such assignment shall not relieve the assigning party of its obligations hereunder. This Agreement shall be binding upon each Party’s heirs, executors, administrators, successors and permitted assigns (whichever is applicable).

10.
