(b) On the date specified by the Second Lien Collateral Trustee (on behalf of the Second Lien Purchasers) in such irrevocable commitment (which shall not be less than five Business Days nor more than 20 Business Days, after the receipt by the Priority Lien Agent of such irrevocable commitment), the Priority Lien Secured Parties shall sell to the Second Lien Purchasers all (but not less than all) Priority Lien Obligations (including unfunded commitments but excluding Excess Priority Lien Obligations) and any loans provided by any of the Priority Lien Secured Parties in connection with a DIP Financing that are outstanding on the date of such sale, subject to any required approval of any Governmental Authority then in effect, if any, and only if on the date of such sale, the Priority Lien Agent receives the following:

(i) payment, as the purchase price for all Priority Lien Obligations sold in such sale, of an amount equal to the full amount of all Priority Lien Obligations (other than (x) outstanding letters of credit as referred to in clause (ii) below and (y) any Priority Lien Obligations constituting Excess Priority Lien Obligations) and loans provided by any of the Priority Lien Secured Parties in connection with a DIP Financing then outstanding (including principal, interest, fees, reasonable attorneys’ fees and legal expenses, but excluding contingent indemnification obligations for which no claim or demand for payment has been made at or prior to such time); provided that in the case of Hedging Obligations that constitute Priority Lien Obligations the Second Lien Purchasers shall cause the applicable agreements governing such Hedging Obligations to be assigned and novated or, if such agreements have been terminated, such purchase price shall include an amount equal to the sum of any unpaid amounts then due in respect of such Hedging Obligations, calculated using the market quotation method and after giving effect to any netting arrangements;

(ii) a cash collateral deposit in such amount as the Priority Lien Agent determines is reasonably necessary to secure the payment of any outstanding letters of credit constituting Priority Lien Obligations that may become due and payable after such sale (but not in any event in an amount greater than one hundred five percent (105%) of the amount then reasonably estimated by the Priority Lien Agent to be the aggregate outstanding amount of such letters of credit at such time), which cash collateral shall be (A) held by the Priority Lien Agent as security solely to reimburse the issuers of such letters of credit that become due and payable after such sale and any fees and expenses incurred in connection with such letters of credit and (B) returned to the Second Lien Collateral Trustee (except as may otherwise be required by applicable law or any order of any court or other Governmental Authority) promptly after the expiration or termination from time to time of all payment contingencies affecting such letters of credit; and

(iii) any agreements, documents or instruments which the Priority Lien Agent may reasonably request pursuant to which the Second Lien Collateral Trustee and the Second Lien Purchasers in such sale expressly assume and adopt all of the obligations of the Priority Lien Agent and the Priority Lien Secured Parties under the Priority Lien Documents and in connection with loans provided by any of the Priority Lien Secured Parties in connection with a DIP Financing on and after the date of the purchase and sale and the Second Lien Collateral Trustee (or any other representative appointed by the holders of a majority in aggregate principal amount of the Second Lien Term Loans then outstanding) becomes a successor agent thereunder.

(c) Such purchase of the Priority Lien Obligations (including unfunded commitments but excluding Excess Priority Lien Obligations) and any loans provided by any of the Secured Parties in connection with a DIP Financing shall be made on a pro rata basis among the Second Lien Purchasers giving notice to the Priority Lien Agent of their interest to exercise the purchase option hereunder according to each such Second Lien Purchaser’s portion of the Second Lien Debt outstanding on the date of purchase or such portion as such Second Lien Purchasers may otherwise agree among themselves. Such purchase price and cash collateral shall be remitted by wire transfer in federal funds to such bank account of the Priority Lien Agent as the Priority Lien Agent may designate in writing to the Second Lien Collateral Trustee for such purpose. Interest shall be calculated to but excluding the Business Day on which such sale occurs if the amounts so paid by the Second Lien Purchasers to the bank account designated by the Priority Lien Agent are received in such bank account prior to 12:00 noon, New York City time, and interest shall be calculated to and including such Business Day if the amounts so paid by the Second Lien Purchasers to the bank account designated by the Priority Lien Agent are received in such bank account later than 12:00 noon, New York City time.

(d) Such sale shall be expressly made without representation or warranty of any kind by the Priority Lien Secured Parties as to the Priority Lien Obligations, the Collateral or otherwise and without recourse to any Priority Lien Secured Party, except that the Priority Lien Secured Parties shall represent and warrant severally as to the Priority Lien Obligations (including unfunded commitments) and any loans provided by any of the Priority Lien Secured Parties in connection with a DIP Financing then owing to it: (i) that such applicable Priority Lien Secured Party owns such Priority Lien Obligations (including unfunded commitments) and any loans provided by any of the Priority Lien Secured Parties in connection with a DIP Financing free and clear of any Liens; and (ii) that such applicable Priority Lien Secured Party has the necessary corporate or other governing authority to assign such interests.

Each of the Second Lien Collateral Trustee, for itself and on behalf of each other Second Lien Secured Party, and the Third Lien Collateral Trustee, for itself and on behalf of each other Third Lien Secured Party, agrees that if, at any time, a Second Lien Secured Party or a Third Lien Secured Party, as applicable, receives notice of any Recovery, the Second Lien Collateral Trustee, any other Second Lien Secured Party, the Third Lien Collateral Trustee or any other Third Lien Secured Party, as applicable, shall promptly pay over to the Priority Lien Agent any payment received by it and then in its possession or under its control in respect of any Collateral subject to any Priority Lien securing such Priority Lien Obligations and shall promptly turn any Collateral subject to any such Priority Lien then held by it over to the Priority Lien Agent, and the provisions set forth in this Agreement shall be reinstated as if such payment had not been made.

(b) W&T will be permitted to designate as an additional holder of Second Lien Obligations or Third Lien Obligations hereunder each Person who is, or who becomes, the registered holder of Second Lien Debt or Third Lien Debt, as applicable, incurred by W&T after the date of this Agreement in accordance with the terms of all applicable Secured Debt Documents.

(ii) an authorized agent, trustee or other representative on behalf of the holders or lenders of any Additional Second Lien Obligations, Initial Third Lien Obligations or Additional Third Lien Obligations, as applicable, must be designated as an additional holder of Secured Obligations hereunder and must, prior to such designation, sign and deliver on behalf of the holders or lenders of such Additional Second Lien Obligations, Initial Third Lien Obligations or Additional Third Lien Obligations, as applicable, a Priority Confirmation Joinder, and, to the extent necessary or appropriate to facilitate such transaction, a new intercreditor agreement substantially similar to this Agreement, as in effect on the date hereof; and

(c) W&T will be permitted to enter into an Initial Third Lien Debt Facility to the extent such Initial Third Lien Debt Facility is permitted by the Priority Credit Agreement, the other Priority Lien Documents, the Term Loan Credit Agreement and the other Second Lien Documents. Any Third Lien Debt incurred pursuant to such Initial Third Lien Debt Facility may be secured by a Third Lien under and pursuant to the Initial Third Lien Security Documents provided the Third Lien Collateral Trustee, acting for itself and on behalf of the Initial Third Lien Secured Parties, becomes a party to this Agreement by satisfying the conditions set forth in clauses (i) and (ii) of the immediately succeeding paragraph.

Notwithstanding the foregoing, nothing in this Agreement will be construed to allow W&T or any other Grantor to incur additional indebtedness unless otherwise permitted by the terms of each applicable Secured Debt Document.

Each of the then-exiting Priority Lien Agent, the Second Lien Collateral Trustee and the Third Lien Collateral Trustee shall be authorized to execute and deliver such documents and agreements (including amendments or supplements to this Agreement) as such holders, lenders, agent, trustee or other representative may reasonably request to give effect to any such Replacement or any incurrence of Additional Second Lien Obligations, Initial Third Lien Obligations or Additional Third Lien Obligations, it being understood that the Priority Lien Agent, the Second Lien Collateral Trustee and the Third Lien Collateral Trustee or (if permitted by the terms of the applicable Secured Debt Documents) the Grantors, without the consent of any other Secured Party or (in the case of the Grantors) one or more Secured Debt Representatives, may amend, supplement, modify or restate this Agreement to the extent necessary or appropriate to facilitate such amendments or supplements to effect such Replacement or incurrence all at the expense of the Grantors.

The Priority Lien Agent acting pursuant to this Section 5.01 shall not have by reason of the Priority Lien Security Documents, the Second Lien Security Documents, the Third Lien Security

Documents, this Agreement or any other document or theory, a fiduciary relationship in respect of any Priority Lien Secured Party, the Second Lien Collateral Trustee, any Second Lien Secured Party, the Third Lien Collateral Trustee or any Third Lien Secured Party.

It is agreed that the obligations of the Second Lien Collateral Trustee and the rights of the Priority Lien Agent and the other Priority Secured Parties and Third Lien Collateral Trustee and the other Third Lien Secured Parties in connection with any such bailment arrangement will be in all respects subject to the provisions of Article II.

The Second Lien Collateral Trustee acting pursuant to this Section 5.01 shall not have by reason of the Priority Lien Documents, the Second Lien Security Documents, the Third Lien Security Documents, this Agreement or any other document or theory, a fiduciary relationship in respect of any Priority Secured Party, any Second Lien Secured Party, the Third Lien Collateral Trustee or any Third Lien Secured Party. Subject to Section 4.03, from and after the Discharge of Second Lien Obligations, the Second Lien Collateral Trustee shall take all such actions in its power as shall reasonably be requested by the Third Lien Collateral Trustee (at the sole cost and expense of the Grantors) to transfer possession or control of such Collateral or any such Account (in each case to the extent the Priority Lien Agent or Third Lien Collateral Trustee has a Lien on such Collateral or Account after giving effect to any prior or concurrent releases of Liens) to the Priority Lien Agent for the benefit of all Priority Secured Parties or the Third Lien Collateral Trustee for the benefit of all Third Lien Secured Parties.

Unless the Second Liens on such Collateral shall have been or concurrently are released, after the occurrence of Discharge of Priority Lien Obligations, the Priority Lien Agent shall, at the request of the Second Lien Collateral Trustee, cooperate with the Grantors and the Second Lien Collateral Trustee (at the expense of the Grantors) in permitting control of any other Accounts to be transferred to the Second Lien Collateral Trustee (or for other arrangements with respect to each such Accounts satisfactory to the Second Lien Collateral Trustee to be made).
