 THE EXCHANGE OFFER AND CONSENT SOLICITATION 

The following is a brief summary of certain terms of the Exchange Offer and Consent Solicitation. It may not contain all the information
that is important to you. For additional information regarding the Exchange Offer and Consent Solicitation, the New Second Lien Notes and the New Unsecured Notes, see “Description of the Exchange Offer and Consent Solicitation,”
“Description of the New Second Lien Notes” and “Description of the New Unsecured Notes.” 
  

			
	The Offeror	  	W&T Offshore, Inc., a Texas corporation.
		
	Exchange Offer	  	W&T is offering to exchange, upon the terms and subject to the conditions set forth in this offering memorandum and related letter of transmittal, up to (i) 62,100,000 Shares, (ii) $202.5 million aggregate principal amount of
New Second Lien Notes and (iii) 180.0 million aggregate principal amount of New Unsecured Notes, for any and all Existing Notes that are validly tendered and not validly withdrawn by Eligible Holders. The Eligible Holders of the Existing Notes
accepted for exchange will receive the Total Exchange Consideration as described under “—Total Exchange Consideration” below for the Existing Notes validly tendered on or before the Early Participation Date and not validly withdrawn.
For Existing Notes validly tendered after the Early Participation Date and on or before the Expiration Date, the Eligible Holders of the Existing Notes accepted for exchange will be eligible to receive the Exchange Consideration as described under
“—Exchange Consideration” below, which equals the Total Exchange Consideration less the Early Tender Premium. Eligible Holders of Existing Notes accepted for exchange in the Exchange Offer will also receive a cash payment equal to the
accrued and unpaid interest in respect of such Existing Notes from June 15, 2016 (the most recent interest payment date) to, but not including, the Settlement Date. Interest on the New Second Lien Notes and the New Unsecured Notes will accrue from
the Settlement Date.
		
	Existing Notes	  	$900.0 million aggregate principal amount of outstanding 8.500% Senior Notes due 2019.
		
	 Holders Eligible to Participate in the Exchange Offer
	  	W&T will conduct the Exchange Offer in accordance with the applicable requirements of the Securities Act and the Exchange Act and the rules and regulations of the SEC thereunder. The Exchange Offer is being made only to Eligible
Holders. By exchanging Existing Notes in the

  
 A-2 

			
		  	 Exchange Offer, Eligible Holders will be making a series of representations and warranties to us. An Eligible Holder is either a QIB as
defined in Rule 144A, or a person that is not a “U.S. person” within the meaning of Regulation S.
  

Only holders of Existing Notes who have properly completed and returned the eligibility certification, which is available in the form approved by us from the
Information Agent (as defined herein), are authorized to receive and review this offering memorandum and to participate in the Exchange Offer.

		
	 Total Exchange Consideration; Early Tender Premium
	  	For each $1,000 principal amount of Existing Notes validly tendered on or before the Early Participation Date and not validly withdrawn, Eligible Holders will be eligible to receive the Total Exchange Consideration, which will be
equal to the Exchange Consideration plus the Early Tender Premium of $25 in principal amount of New Second Lien Notes for each $1,000 principal amount of Existing Notes accepted for exchange. If the Exchange Offer is completed, the Early Tender
Premium will be issued only to Eligible Holders who validly tender their Existing Notes on or before the Early Participation Date and do not validly withdraw their tenders and whose Existing Notes are accepted for exchange. Eligible Holders who
validly tender their Existing Notes after the Early Participation Date but before the Expiration Date will not be eligible to receive the Early Tender Premium. See “Description of the Exchange Offer and Consent Solicitation—Total Exchange
Consideration; Early Tender Premium.”
		
	Exchange Consideration	  	The Exchange Consideration will consist of the following for each $1,000 principal amount of Existing Notes accepted for exchange that were validly tendered on or before the Expiration Date: (i) 69 Shares, (ii) $200 in principal
amount of New Second Lien Notes and (iii) $200 in principal amount of New Unsecured Notes. See “Description of the Exchange Offer and Consent Solicitation—The Exchange Offer.”
		
	Accrued and Unpaid Interest	  	In addition to the Total Exchange Consideration or Exchange Consideration, as the case may be, with respect to Existing Notes accepted pursuant to the Exchange Offer, each Eligible Holder will receive accrued and unpaid interest on
its accepted Existing Notes from June 15, 2016 (the last interest payment date) to, but not including, the Settlement Date.

  
 A-3 

			
	Early Participation Date	  	 11:59 p.m., New York City time, on August [8], 2016, unless extended by W&T.

 
 W&T reserves the right to extend the Early Participation Date with respect to the
Exchange Offer and Consent Solicitation without extending the Withdrawal Deadline.

		
	Expiration Date	  	The Exchange Offer will expire at 11:59 p.m., New York City time, on August [29], 2016, as the same may be extended for the Exchange Offer and Consent Solicitation.
		
	Settlement Date	  	The Settlement Date for the Exchange Offer will occur promptly following the Expiration Date and is expected to occur on the third business day after the Expiration Date.
		
	Consent Solicitation	  	 Holders who tender Existing Notes pursuant to the Exchange Offer are required to deliver a Consent, which will constitute a consent to the
Amendments to the Existing Indenture, as described further in “The Amendments to the Existing Indenture” and “Annex A: Form of Supplemental Indenture.”
  

By tendering their Existing Notes, Eligible Holders will be deemed to have delivered Consents to the Amendments with respect to such Existing Notes being
tendered.

		
	Requisite Consents; Supplemental Indenture	  	In order to approve the Amendments with respect to the Existing Notes, Consents must be delivered and not revoked in respect of at least a majority of the outstanding principal amount of Existing Notes. Promptly following the
Expiration Date, if the requisite Consents are delivered with respect to the Existing Notes, W&T, the guarantors under the Existing Notes and the trustee for the Existing Notes will enter into a supplemental indenture to give effect to the
Amendments. The Amendments will not become operative until the consummation of the Exchange Offer. See “Description of the Exchange Offer and Consent Solicitation—Conditions to the Exchange Offer.” The calculation of the requisite
Consents for the Existing Notes does not include any Existing Notes held by us or our affiliates. In the event that we do not consummate the Exchange Offer for any reason, the indenture governing the Existing Notes will remain in effect in its
current form. The consummation of the Exchange Offer is conditioned upon the receipt of the requisite

  
 A-4 

			
		  	Consents to approve the applicable Amendments and the execution and delivery of the supplemental indenture giving effect to such Amendments. We may not consummate the Exchange Offer or execute the supplemental indenture without
receiving the requisite Consents pursuant to the Consent Solicitations. See “The Amendments to the Existing Indenture.”
		
	Withdrawal of Tenders	  	Tenders of Existing Notes in the Exchange Offer may be validly withdrawn at any time on or prior to the Withdrawal Deadline except in certain limited circumstances as set forth herein. The Withdrawal Deadline will be 11:59 p.m., New
York City time, on August [8], 2016, unless extended or earlier terminated. Tenders submitted in the Exchange Offer after the Withdrawal Deadline will be irrevocable except in the limited circumstances where additional withdrawal rights are required
by law. See “Description of the Exchange Offer and Consent Solicitation—Withdrawal of Tenders.”
		
	Conditions to the Exchange Offer	  	W&T’s obligation to accept Existing Notes in the Exchange Offer is subject to (a) the valid tender, without withdrawal, of a minimum of 95%, or $855.0 million, of the outstanding aggregate principal amount of Existing Notes
by Eligible Holders as of the Expiration Date, (b) the Requisite Consents having been received, without withdrawal, prior to the Expiration Date, (c) the approval by our shareholders of both the Authorized Shares Proposal and the Exchange Offer
Proposal at the Special Meeting, (d) the amendment to our revolving bank credit facility to permit the consummation of the Exchange Offer and (e) the General Conditions. Subject to applicable law, W&T expressly reserves the right, in
consultation with the Required Holders, to amend the Exchange Offer in any respect and to terminate the Exchange Offer if the conditions to the Exchange Offer are not satisfied. If the Exchange Offer is terminated at any time, the Existing Notes
tendered pursuant to the Exchange Offer will be promptly returned to the tendering Eligible Holders. W&T may waive, at any time prior to the Expiration Date, the Minimum Tender Condition1 in
consultation with the Required

  

	1 	 The “Minimum Tender Condition” is defined as the valid tender, without withdrawal, of a minimum of 95%,
or $855.0 million, of the outstanding aggregate principal amount of Existing Notes by Eligible Holders as of the Expiration Date. 

  
 A-5 

			
		  	 Holders and any of the General Conditions. If W&T waives the Minimum Tender Condition, W&T shall not be obligated to extend the
Withdrawal Deadline. Accordingly, the aggregate principal amount of Existing Notes accepted for exchange pursuant to the Exchange Offer may be significantly less than the aggregate principal amount set forth by the Minimum Tender Condition.

 
 See “Description of the Exchange Offer and Consent Solicitation—Conditions to
the Exchange Offer.”

		
	Minimum Tender Condition	  	95%.
		
	Termination; Extension; Amendment	  	W&T, in its sole discretion, may extend the Early Participation Date and the Expiration Date with respect to the Exchange Offer and Consent Solicitation, subject to applicable law. W&T expressly reserves the right, in its
sole discretion and with respect to the Exchange Offer and Consent Solicitation, to: (i) delay accepting any Existing Notes, extend the Exchange Offer and Consent Solicitation or terminate the Exchange Offer and Consent Solicitation and not accept
any Existing Notes; (ii) extend the Early Participation Date without extending the Withdrawal Deadline; and (iii) amend, modify or waive in part or whole, at any time, or from time to time, the terms of the Exchange Offer and Consent Solicitation in
any respect, including waiver of any conditions to consummation of the Exchange Offer. See “Description of the Exchange Offer and Consent Solicitation—Early Participation Date; Expiration Date; Extensions; Amendments;
Termination.”
		
	Procedures for Tendering	  	If Eligible Holders wish to participate in the Exchange Offer and Consent Solicitation, and their Existing Notes are held by a custodial entity, such as a bank, broker, dealer, trust company or other nominee, Eligible Holders must
instruct that custodial entity to tender their Existing Notes on their behalf pursuant to the procedures of that custodial entity. Eligible Holders are encouraged to contact their custodial entity as soon as possible to give them sufficient time to
meet the requested deadline. Custodial entities that are participants in DTC must tender Existing Notes through the ATOP maintained by DTC, by which tender the custodial entity and the beneficial owner on whose behalf the custodial entity is acting
agree to be bound by the terms and conditions set forth herein and in the letter of transmittal.

  
 A-6 

			
		  	 Eligible Holders that are beneficial owners that hold Existing Notes through Euroclear or Clearstream and wish to tender their Existing
Notes, must instruct Euroclear or Clearstream, as the case may be, to tender such Existing Notes and block the account in respect of the tendered Existing Notes in accordance with the procedures established by Euroclear or Clearstream. Eligible
Holders are encouraged to contact Euroclear or Clearstream directly to ascertain their procedures for tendering Notes.
  

See “Description of the Exchange Offer and Consent Solicitation— Procedures for Tendering.”

 
 For further information, Eligible Holders should contact the Dealer Manager, the
Information Agent or the Exchange Agent at their respective telephone numbers and addresses set forth on the back cover of this offering memorandum or consult their broker, dealer, commercial bank, trust company or other nominee for
assistance.

		
	Consequences for Failure to Exchange	  	 Existing Notes that are not validly tendered or that are validly tendered but validly withdrawn will remain outstanding and will continue to
be subject to their existing terms.
  
 The trading market for outstanding Existing Notes
not exchanged in the Exchange Offer may be more limited than it is at present. Therefore, if your Existing Notes are not tendered and accepted in the Exchange Offer, it may become more difficult for you to sell or transfer your unexchanged Existing
Notes.
  
 Claims regarding the Existing Notes remaining outstanding following the
completion of the Exchange Offer will be effectively subordinated to claims with respect to the New Second Lien Notes to the extent of the value of the collateral and effectively pari passu with the New Unsecured Notes, assuming the Minimum
Tender Condition is satisfied. In the event the Minimum Tender Condition is not satisfied and at least two-thirds of the participating holders party to a Support Agreement (the “Support Agreement”) in terms of aggregated principal amount
of Existing Notes do not waive such Minimum Tender Condition, the Existing Notes will be effectively subordinated to claims with respect to the New Unsecured Notes to the extent of the value of the
collateral.

		  	See “Risk Factors” for a more detailed description of the foregoing risks and other risks relating to the Exchange Offer and Consent Solicitation.
		
	Support Agreement	  	W&T has entered into the Support Agreement with holders of [●]% of the aggregate principal amount of outstanding Existing Notes, pursuant to which such holders have agreed to tender their Existing Notes in the Exchange
Offer.
		
	New Capital Financing	  	 Simultaneously with the closing of the Exchange Offering, W&T expects to enter into a 1.5 lien secured term loan facility in the
principal amount of $75.0 million (the “New Capital Financing”).
  
 The New
Capital Financing will be open, on a pro rata basis, only to holders of Existing Notes who enter into the Support Agreement and enter into a commitment letter with W&T to provide the New Capital Financing for up to the full $75.0 million
principal amount of 1.5 lien secured term loans; provided that each participant in the New Capital Financing must hold 1.5 lien secured term loans in a principal amount of at least $1,000,000.

		
	Brokerage Fees and Commissions	  	No brokerage fees or commissions are payable by the holders of the Existing Notes to the Dealer Manager, the Exchange Agent or W&T in connection with the Exchange Offer and Consent Solicitation. If a tendering holder handles the
transaction through its broker, dealer, commercial bank, trust company or other institution, that holder may be required to pay brokerage fees or commissions.
		
	[Original Issue Discount	  	 The New Second Lien Notes and the New Unsecured Notes issued in the Exchange Offer will be treated as issued with original issue discount for
U.S. federal income tax purposes if the difference between the principal amount of
 the New Second Lien Notes and the New Unsecured Notes and their
respective issue price is equal to or greater than a specified de minimis amount. If the New Second Lien Notes or the New Unsecured Notes are treated as having original issue discount, U.S. Holders (as defined in “Certain U.S. Federal
Income Tax Considerations”), whether on the cash or accrual method of tax accounting, will be required to include any amounts representing original issue discount in gross income (as ordinary income) on a constant yield to maturity basis for
U.S. federal income tax purposes in advance of the receipt of

 DESCRIPTION OF THE EXCHANGE OFFER AND CONSENT SOLICITATION 

The Exchange Offer; Exchange Consideration 

W&T is offering to exchange, upon the terms and subject to the conditions set forth in this offering memorandum and the related letter of
transmittal. 
 Eligible Holders of Existing Notes will be eligible to receive the applicable Total Exchange Consideration set forth under
“—Total Exchange Consideration; Early Tender Premium” below for Existing Notes validly tendered at or before the Early Participation Date and not validly withdrawn. For Existing Notes validly tendered after the Early Participation
Date and before the Expiration Date, Eligible Holders of Existing Notes will be eligible to receive the Exchange Consideration, which will consist of (i) 69 Shares, (ii) $200 in principal amount of New Second Lien Notes and (iii) $200 in principal
amount of New Unsecured Notes, for each $1,000 principal amount of Existing Notes validly tendered on or before the Expiration Date and accepted for exchange. In addition, Eligible Holders whose Existing Notes are accepted for exchange pursuant to
the Exchange Offer will receive a cash payment representing accrued and unpaid interest on their Existing Notes to, but not including, the Settlement Date. 

Existing Notes may be tendered only in principal amounts equal to minimum denominations of $2,000 and integral multiples of $1,000 in excess
thereof. No alternative, conditional or contingent tenders will be accepted. Eligible Holders who do not tender all of their Existing Notes should ensure that they retain a principal amount of Existing Notes amounting to at least the minimum
denomination equal to $2,000. 
 The New Second Lien Notes and New Unsecured Notes will only be issued in minimum denominations of $2,000
and integral multiples of $1,000 in excess thereof. No tender of Existing Notes will be accepted if it results in the issuance of less than $2,000 principal amount of either New Second Lien Notes or New Unsecured Notes. If, pursuant to the Exchange
Offer, a tendering Eligible Holder would otherwise be entitled to receive a principal amount of New Second Lien Notes or New Unsecured Notes that is not equal to $2,000 or an integral multiple of $1,000 in excess thereof, such principal amount will
be rounded down to the nearest $2,000 or integral multiple of $1,000 in excess thereof. This rounded amount will be the principal amount of the New Second Lien Notes or New Unsecured Notes, as the case may be, such Eligible Holder will receive and
no cash will be paid in lieu of any principal amount of either New Second Lien Notes or New Unsecured Notes as a result of the rounding down. 
 Total
Exchange Consideration; Early Tender Premium 
 For each $1,000 principal amount of Existing Notes accepted for exchange that were
validly tendered at or before the Early Participation Date and not validly withdrawn, Eligible Holders of Existing Notes will be eligible to receive the Total Exchange Consideration, which equals the Exchange Consideration plus the Early Tender
Premium. For each $1,000 principal amount of Existing Notes accepted for exchange that is validly tendered after the Early Participation Date but prior to the Expiration Date, Eligible Holders of Existing Notes will be eligible to receive only the
Exchange Consideration, which does not include the Early Tender Premium. In addition to the Exchange Consideration or the Total Exchange Consideration, Eligible Holders of Existing Notes accepted for exchange in the Exchange Offer will also receive
a cash payment equal to the accrued and unpaid interest in respect of such Existing Notes from June 15, 2016 (the most recent interest payment date) to, but not including, the Settlement Date.

 Early Participation Date;
Expiration Date; Extensions; Amendments; Termination 
 The Early Participation Date is 11:59 p.m., New York City time, on August [8],
2016, subject to W&T’s right to extend that time and date in W&T’s sole discretion (which right is subject to applicable law), in which case the Early Participation Date means the latest time and date to which the Early
Participation Date is extended. The Expiration Date is 11:59 p.m., New York City time, on August [29], 2016, subject to W&T’s right to extend that time and date (which right is subject to applicable law) in consultation with the Required
Holders (which right is subject to applicable law), in which case the Expiration Date means the latest time and date to which the Exchange Offer and Consent Solicitation is extended. To extend the Expiration Date, W&T will notify the Exchange
Agent and will make a public announcement thereof before 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date. The public announcement will include the approximate principal amount of the Existing
Notes that had been validly tendered and not validly withdrawn. During any extension of the Early Participation Date or the Expiration Date, all Existing Notes previously tendered in an extended Exchange Offer will remain subject to such Exchange
Offer and may be accepted for exchange by W&T. 
 Subject to applicable law, W&T expressly reserves the right, in its sole
discretion, to: 
  

	 	•	 	delay accepting any Existing Notes, to extend the Exchange Offer and Consent Solicitation or to terminate the Exchange Offer and not accept any Existing Notes; 

 

	 	•	 	extend the Early Participation Date without extending the Withdrawal Deadline; and 

  

	 	•	 	amend, modify or waive in part or whole, at any time, or from time to time, the terms of the Exchange Offer in any respect, including waiver of any conditions to consummation of the Exchange Offer; provided,
however, that W&T may only waive the Minimum Tender Condition or modify the Exchange Consideration in consultation with the Required Holders. 

If W&T exercises any such right, it will give written notice thereof to the Exchange Agent and will make a public announcement thereof as
promptly as practicable. Without limiting the manner in which W&T may choose to make a public announcement of any extension, amendment or termination of the Exchange Offer and Consent Solicitation, W&T will not be obligated to publish,
advertise or otherwise communicate any such public announcement, other than by making a timely press release. The minimum period during which the Exchange Offer and Consent Solicitation will remain open following

  
 A-11 

 
material changes in the terms of the Exchange Offer and Consent Solicitation or in the information concerning the Exchange Offer and Consent Solicitation will depend upon the facts and
circumstances of such change, including the relative materiality of the changes. In accordance with Rule 14e-1 under the Exchange Act, if W&T elects to change the consideration offered or the Existing Notes sought, the Exchange Offer will remain
open for a minimum ten business-day period following the date that the notice of such change is first published or sent to Eligible Holders. If the terms of the Exchange Offer are amended in a manner determined by W&T to constitute a material
change adversely affecting any Eligible Holder, W&T will promptly disclose any such amendment in a manner reasonably calculated to inform Eligible Holders of such amendment, and W&T will extend the Exchange Offer and Consent Solicitation for
a time period that it deems appropriate, depending upon the significance of the amendment and the manner of disclosure to Eligible Holders, if the Exchange Offer and Consent Solicitation would otherwise expire during such time period. For the
avoidance of doubt, if W&T waives the Minimum Tender Condition, W&T will not be obligated to extend the Withdrawal Deadline. 
 Settlement Date

 The Settlement Date will occur promptly after the Expiration Date and is expected to occur on the third business day after the
Expiration Date. W&T will not be obligated to deliver Shares, New Second Lien Notes, New Unsecured Notes and any cash payments unless the Exchange Offer is consummated. 

Holders Eligible to Participate in the Exchange Offer 

W&T will conduct the Exchange Offer in accordance with the applicable requirements of the Securities Act and the Exchange Act and the rules
and regulations of the SEC thereunder. Prior to the distribution of this offering memorandum, Eligible Holders of Existing Notes have certified that each such holder is either a QIB as defined in Rule 144A, or a person that is not a “U.S.
person” within the meaning of Regulation S. 
 Only Eligible Holders of Existing Notes who have properly completed and returned the
eligibility certification, which is available from the Information Agent, are authorized to receive and review this offering memorandum and to participate in the Exchange Offer. 

Consent Solicitation 
 Holders who tender
Existing Notes pursuant to the Exchange Offer are required to deliver a Consent, which will constitute a consent to the Amendments to the Existing Indenture, as described further in “The Amendments to the Existing Indenture” and
“Annex A: Form of Supplemental Indenture.” By tendering their Existing Notes, Eligible Holders will be deemed to have delivered Consents to the Amendments with respect to such Existing Notes being tendered. 

In order to approve the Amendments with respect to the Existing Notes, Consents must be delivered and not revoked in respect of at least a
majority of the outstanding principal amount of Existing Notes. Promptly following the Expiration Date, if the requisite Consents are delivered with respect to the Existing Notes, W&T, the guarantors under the Existing Notes and the trustee
for the Existing Notes will enter into a supplemental indenture to give effect to the Amendments. The Amendments will not become operative until the consummation of the Exchange Offer. The calculation of the requisite Consents for the Existing Notes
does not include any Existing Notes held by us or our affiliates. In the event that we do not consummate the Exchange Offer for any reason, the indenture governing the Existing Notes will remain in effect in its current form. The consummation of the
Exchange Offer is conditioned upon the receipt of the requisite Consents to approve the applicable Amendments and the execution and delivery of the supplemental indenture giving effect to such Amendments. W&T may not consummate the Exchange
Offer or execute the supplemental indenture without receiving the requisite Consents pursuant to the Consent Solicitations. See “The Amendments to the Existing Indenture.” 

  
 A-12 

 Conditions to the Exchange Offer 

W&T’s obligation to accept for exchange Existing Notes validly tendered pursuant to the Exchange Offer is subject to (a) the valid
tender, without withdrawal, of a minimum of 95%, or $855.0 million, of the outstanding aggregate principal amount of Existing Notes by Eligible Holders as of the Expiration Date; (b) the Consents from Holders of at least a majority of the
outstanding principal amount of the Existing Notes to the Amendments having been received, without withdrawal, prior to the Expiration Date to permit the issuance of the New Second Lien Notes under the Existing Indenture; (c) the approval by our
shareholders of both the Authorized Shares Proposal and the Exchange Offer Proposal at the Special Meeting; and (d) the amendment to our revolving bank credit facility to permit the consummation of the Exchange Offer. Additionally,
notwithstanding any other provision of this offering memorandum, W&T will not be required to accept for exchange Existing Notes tendered pursuant to the Exchange Offer and may terminate, extend or amend the Exchange Offer and Consent
Solicitation and may postpone the acceptance for exchange of Existing Notes so tendered if the General Conditions have not been satisfied or waived. W&T may waive, at any time prior to the Expiration Date, the Minimum Tender Condition in
consultation with the Required Holders and any of the General Conditions. Accordingly, the aggregate principal amount of Existing Notes accepted for exchange pursuant to the Exchange Offer may be significantly less than the aggregate principal
amount set forth by the Minimum Tender Condition. 
 General Conditions 

All of the “General Conditions” shall be deemed to be satisfied unless any of the following conditions shall occur on or after
the date of this offering memorandum and at or prior to the Expiration Date: 
  

	 	•	 	there shall have been instituted, threatened or be pending any action, proceeding or investigation (whether formal or informal) (or there shall have been any material adverse development with respect to any action or
proceeding currently instituted, threatened or pending) before or by any court, governmental, regulatory or administrative agency or instrumentality, or by any other person, in connection with the Exchange Offer that, in our reasonable judgment
either (a) is, or is likely to be, adverse to our business, operations, properties, condition (financial or otherwise), assets, liabilities or prospects, or (b) would or might prohibit, prevent, restrict or delay consummation of the Exchange Offer;

  

	 	•	 	an order, statute, rule, regulation, executive order, stay, decree, judgment or injunction shall have been proposed, enacted, entered, issued, promulgated, enforced or deemed applicable by any court or governmental,
regulatory or administrative agency or instrumentality that, in our reasonable judgment, either (a) would or might prohibit, prevent, restrict or delay consummation of the Exchange Offer, or (b) is, or is likely to be, materially adverse to our
business, operations, properties, condition (financial or otherwise), assets, liabilities or prospects; 

  

	 	•	 	there shall have occurred or be likely to occur any event affecting our or our subsidiaries’ business or financial affairs that, in our reasonable judgment, would or might prohibit, prevent, restrict or delay
consummation of the Exchange Offer; 

  

	 	•	 	the trustee shall have objected in any respect to or taken action that could, in our reasonable judgment, adversely affect the consummation of the Exchange Offer or shall have taken any action that challenges the
validity or effectiveness of the procedures used by us in the making of the Exchange Offer or the acceptance of, or payment for, the Existing Notes; or 

  

	 	•	 	there has occurred (a) any general suspension of, or limitation on prices for, trading in securities in the United States securities or financial markets, (b) a declaration of a banking moratorium or any suspension of
payments with respect to banks in the United States or other major financial markets, (c) any limitation (whether or not mandatory) by any government or governmental, administrative or regulatory authority or agency, domestic or foreign, or other
event that, in our reasonable judgment, might affect the extension of credit by banks or other lending institutions, (d) a commencement of a war, armed hostilities, terrorist acts or other national or international calamity directly or indirectly
involving the United States, or (e) in the case of any of the foregoing existing on the date hereof, in our reasonable judgment, a material acceleration or worsening thereof. 

  
 A-13 

 Additional Information 

The General Conditions are for our sole benefit and may be asserted by us regardless of the circumstances, including any action or inaction by
us, giving rise to such condition or may be waived by us in whole or in part at any time, and from time to time, prior to the Expiration Date in our sole discretion. If any condition to the Exchange Offer (including the General Conditions) is not
satisfied or waived by us prior to the Expiration Date, we reserve the right, but will not be obligated, subject to applicable law: 
  

	 	•	 	to terminate the Exchange Offer and return any tendered Existing Notes; 

  

	 	•	 	to waive all unsatisfied conditions and accept for exchange all Existing Notes that are validly tendered prior to the Expiration Date; 

 

	 	•	 	to extend the Exchange Offer and retain the Existing Notes that have been tendered during the period for which the Exchange Offer is extended; or 

 

	 	•	 	to amend the Exchange Offer. 

 The failure by us at any time to exercise any of the foregoing
rights will not be deemed a waiver of any other right and each right will be deemed an ongoing right that may be asserted at any time and from time to time. Any determination made by us concerning an event, development or circumstance described or
referred to above will be final and binding on all parties. 
 Treatment of Existing Notes Not Tendered in the Exchange Offer 

Existing Notes that are not tendered or that are tendered but not accepted will remain outstanding and will continue to be subject to their
existing terms immediately following the completion of the Exchange Offer. The Existing Notes that remain outstanding will be effectively junior, to the extent of the value of the collateral, to our and the subsidiary guarantors’ secured
obligations, including our revolving bank credit facility, the New Second Lien Notes, the Existing Term Loans and any other lien obligations, including the New Unsecured Notes in the event the Minimum Tender Condition is not satisfied and at least
two-thirds of the participating holders party to the Support Agreement in terms of aggregated principal amount of Existing Notes do not waive such Minimum Tender Condition. 

From time to time before or after the Expiration Date, W&T or its affiliates may acquire any Existing Notes that are not tendered and
accepted in the Exchange Offer through open market purchases, 

  
 A-14 

 
privately negotiated transactions, exchange offers, redemption or otherwise, upon such terms and at such prices as W&T may determine (or as may be provided for in the indenture governing the
Existing Notes), which may be more or less than the consideration to be received by participating Eligible Holders in the Exchange Offer and, in either case, could be for cash or other consideration. There can be no assurance as to which, if any, of
these alternatives or combinations thereof W&T or its affiliates may choose to pursue in the future. 
 The trading market for the
Existing Notes that are not exchanged could become more limited than the existing trading market for the Existing Notes and could cease to exist altogether due to the reduction in the principal amount of the Existing Notes outstanding upon
consummation of the Exchange Offer. A more limited trading market might adversely affect the liquidity, market price and price volatility of the Existing Notes. If a market for the Existing Notes that are not exchanged exists or develops, the
Existing Notes may trade at a discount to the price at which they would trade if the principal amount outstanding were not reduced. See “Risk Factors.” 

Effect of Tender 
 Any tender by an
Eligible Holder, and W&T’s subsequent acceptance of that tender, of Existing Notes will constitute a binding agreement between that Eligible Holder and W&T upon the terms and subject to the conditions of the Exchange Offer described in
this offering memorandum and in the letter of transmittal. The participation in the Exchange Offer by a tendering Eligible Holder will constitute the agreement by that Eligible Holder to deliver good and marketable title to the tendered Existing
Notes, free and clear of any and all liens, restrictions, charges, pledges, security interests, encumbrances or rights of any kind of third parties. 

Letter of Transmittal; Representations, Warranties and Covenants of Holders of Existing Notes 

For physical or facsimile delivery of a letter of transmittal, please complete, sign and date the letter of transmittal in accordance with the
instructions set forth therein. A letter of transmittal need not accompany tenders effected through ATOP. Eligible Holders tendering Existing Notes through ATOP will be deemed to agree to the terms set forth in the letter of transmittal pursuant
to an Agent’s Message. 
 Upon the agreement to the terms of the letter of transmittal pursuant to an Agent’s Message or
submission of a letter of transmittal, as applicable (as described under “—Procedures for Tendering”), an Eligible Holder, or the beneficial holder of Existing Notes on behalf of which the Eligible Holder has tendered, will, subject
to that Eligible Holder’s ability to withdraw its tender, and subject to the terms and conditions of the Exchange Offer generally, be deemed, among other things, to: 
  

	 	•	 	irrevocably sell, assign and transfer to or upon W&T’s order or the order of W&T’s nominee all right, title and interest in and to, and any and all claims in respect of or arising or having arisen as a
result of the Eligible Holder’s status as a holder of, all Existing Notes tendered thereby, such that thereafter the Eligible Holder shall have no contractual or other rights or claims in law or equity against any fiduciary, trustee, fiscal
agent or other person connected with the Existing Notes arising under, from or in connection with those Existing Notes; 

  

	 	•	 	waive any and all rights with respect to the Existing Notes tendered thereby, including, without limitation, any existing or past defaults and their consequences in respect of those Existing Notes; and

  

	 	•	 	release and discharge W&T and the trustee with respect to the indentures governing the Existing Notes from any and all claims that the Eligible Holder may have, now or in the future, arising out of or related to the
Existing Notes tendered thereby, including, without limitation, any claims that the Eligible Holder is entitled to receive additional principal or interest payments with respect to the Existing Notes tendered thereby, other than accrued and unpaid
interest on the Existing Notes or as otherwise expressly provided in this offering memorandum and in the letter of transmittal, or to participate in any redemption or defeasance of the Existing Notes tendered thereby. 

  
 A-15 

 In addition, each Eligible Holder of Existing Notes tendered in the Exchange Offer upon the
agreement to the terms of the letter of transmittal pursuant to an Agent’s Message, or the submission of a letter of transmittal, will be deemed to represent, warrant and agree that: 

 

	 	•	 	it has received this offering memorandum; 

  

	 	•	 	it is the beneficial owner (as defined herein) of, or a duly authorized representative of one or more beneficial owners of, the Existing Notes tendered thereby, and it has full power and authority to execute and/or
agree to the letter of transmittal; 

  

	 	•	 	the Existing Notes being tendered thereby were owned as of the date of tender, free and clear of any liens, charges, claims, encumbrances, interests and restrictions of any kind, and W&T will acquire good,
indefeasible and unencumbered title to those Existing Notes, free and clear of all liens, charges, claims, encumbrances, interests and restrictions of any kind, when W&T accepts the same; 

 

	 	•	 	it will not sell, pledge, hypothecate or otherwise encumber or transfer Existing Notes tendered thereby from the date of the letter of transmittal, and any purported sale, pledge, hypothecation or other encumbrance or
transfer will be void and of no effect; 

  

	 	•	 	it is, or, in the event that it is acting on behalf of a beneficial owner of the Existing Notes tendered thereby, it has received a written certification from that beneficial owner, dated as of a specific date on or
since the close of that beneficial owner’s most recent fiscal year, to the effect that that beneficial owner is a QIB and is acquiring Shares, New Second Lien Notes and New Unsecured Notes for its own account or for a discretionary account or
accounts on behalf of one or more QIBs as to which it has been instructed and has the authority to make the statements contained in the letter of transmittal; 

  

	 	•	 	it is not resident and/or located in any Member State of the European Economic Area which has implemented the Prospectus Directive (each a “Relevant Member State”), or if located and/or resident in a Relevant
Member State is a qualified investor as defined in Article 2.1(e) of the Prospectus Directive; 

  

	 	•	 	it is otherwise a person to whom it is lawful to make available this offering memorandum or to make the Exchange Offer in accordance with applicable laws (including the transfer restrictions set out in this offering
memorandum); 

  

	 	•	 	it has had access to such financial and other information and has been afforded the opportunity to ask such questions of representatives of W&T and receive answers thereto, as it deems necessary in connection with
its decision to participate in the Exchange Offer; 

  

	 	•	 	 it acknowledges that W&T, the Dealer Manager, and others will rely upon the truth and accuracy of the
foregoing acknowledgements, representations and agreements and agrees that if any of the 

  
 A-16 

	 	 
acknowledgements, representations and warranties made by its agreement to the terms of a letter of transmittal pursuant to an Agent’s Message, or the submission of a letter of transmittal,
are, at any time prior to the consummation of the Exchange Offer, no longer accurate, it shall promptly notify W&T and the Dealer Manager. If it is acquiring the Shares, New Second Lien Notes and New Unsecured Notes as a fiduciary or agent for
one or more investor accounts, it represents that it has sole investment discretion with respect to each such account and it has full power to make the foregoing acknowledgements, representations and agreements on behalf of such account;

  

	 	•	 	in evaluating the Exchange Offer and in making its decision whether to participate in the Exchange Offer by the tender of Existing Notes, it has made its own independent appraisal of the matters referred to in this
offering memorandum and the letter of transmittal and in any related communications; 

  

	 	•	 	the tender of Existing Notes shall constitute an undertaking to execute any further documents and give any further assurances that may be required in connection with any of the foregoing, in each case on and subject to
the terms and conditions described or referred to in this offering memorandum; 

  

	 	•	 	the agreement to the letter of transmittal pursuant to an Agent’s Message, or the submission of a letter of transmittal, shall, subject to an Eligible Holder’s ability to withdraw its tender on or prior to the
Withdrawal Deadline, and subject to the terms and conditions of the Exchange Offer, constitute the irrevocable appointment of the Exchange Agent as its attorney and agent and an irrevocable instruction to that attorney and agent to complete and
execute all or any forms of transfer and other documents at the discretion of that attorney and agent in relation to the Existing Notes tendered thereby in favor of W&T or any other person or persons as W&T may direct and to deliver those
forms of transfer and other documents in the attorney’s and agent’s discretion and the certificates and other documents of title relating to the registration of Existing Notes and to execute all other documents and to do all other acts and
things as may be in the opinion of that attorney or agent necessary or expedient for the purpose of, or in connection with, the acceptance of the applicable Exchange Offer and to vest in W&T or its nominees those Existing Notes;

  

	 	•	 	either (a) such holder is not (i) an “employee benefit plan” that is subject to Part 4 of Subtitle B of Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), (ii) a
plan to which Section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”), or provisions under any other federal, state, local, non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Code
applies (“Similar Laws”), or (iii) an entity the underlying assets of which are considered to include “plan assets” of such plans or (b) such holder’s acquisition, holding and disposition of the Shares, New Second Lien Notes
and New Unsecured Notes either (i) are not a prohibited transaction under ERISA or the Code or do not violate Similar Laws (ii) are entitled to exemptive relief from the prohibited transaction provisions of ERISA and the Code or under Similar Laws
in accordance with one or more available statutory, class or individual prohibited transaction exemptions; and 

  

	 	•	 	the terms and conditions of the Exchange Offer shall be deemed to be incorporated in, and form a part of, the letter of transmittal, which shall be read and construed accordingly. 

Each Eligible Holder of Existing Notes that agrees to the terms of a letter of transmittal pursuant to an Agent’s Message, or the
submission of a letter of transmittal, will also be deemed to represent, warrant and agree to the terms described under “Transfer Restrictions.” 

  
 A-17 

 The representations, warranties and agreements of an Eligible Holder tendering Existing Notes
will be deemed to be repeated and reconfirmed on and as of the Expiration Date and the Settlement Date. For purposes of this offering memorandum, the “beneficial owner” of any Existing Notes means any Eligible Holder that exercises
investment discretion with respect to those Existing Notes. 
 Absence of Appraisal and Dissenters’ Rights 

Holders of the Existing Notes do not have any appraisal or dissenters’ rights in connection with the Exchange Offer. 

Acceptance of Existing Notes for Exchange and Delivery of the Consideration 

On the Settlement Date, the Shares, New Second Lien Notes and New Unsecured Notes to be issued in exchange for the Existing Notes tendered in
the Exchange Offer, if consummated, will be delivered in book-entry form, and payment of any cash amounts will be made by deposit of funds with DTC, Clearstream or Euroclear, as applicable, which will transmit those payments to tendering Eligible
Holders. 
 For the purposes of the Exchange Offer, the Company will be deemed to have accepted properly tendered Existing Notes for
exchange if and when the Company gives written notice to the Exchange Agent. 
 In all cases, issuance of the Shares, New Second Lien Notes
and New Unsecured Notes for the Existing Notes that are accepted for exchange will be made only: 
  

	 	•	 	upon satisfaction of the waiver by W&T of the Minimum Tender Condition; 

  

	 	•	 	upon satisfaction of the General Conditions; 

  

	 	•	 	in the case of Existing Notes held through DTC, after timely receipt by the Exchange Agent of a timely book-entry confirmation of such Existing Notes into the Exchange Agent’s account at DTC or, in the case of
Existing Notes held through Euroclear or Clearstream, confirmation that the relevant Existing Notes have been tendered and blocked in the relevant Eligible Holder’s account(s) in Euroclear or Clearstream; 

 

	 	•	 	in the case of Existing Notes held through DTC, after timely receipt by the Exchange Agent of an Agent’s Message (as defined below in “—Procedures for Tendering”); and 

 

	 	•	 	all other required documents. 

 Eligible Holders may submit all or part of their Existing Notes
currently held. The Exchange Agent will act as agent for tendering Eligible Holders of Existing Notes for the purpose of receiving Existing Notes and transmitting Shares, New Second Lien Notes and New Unsecured Notes and cash as of the Settlement
Date. If any tendered Existing Notes are not accepted for any reason described in the terms and conditions of the Exchange Offer, such unaccepted Existing Notes will be returned without expense to the tendering Eligible Holders promptly after the
expiration or termination of the Exchange Offer. 
 If, for any reason, acceptance for exchange of tendered Existing Notes, issuance of
Shares, New Second Lien Notes and New Unsecured Notes in exchange for validly tendered Existing Notes, pursuant to the Exchange Offer is delayed, or W&T is unable to accept tendered Existing Notes for exchange or to

  
 A-18 

 
issue Shares, New Second Lien Notes and New Unsecured Notes in exchange for validly tendered Existing Notes pursuant to the Exchange Offer, then the Exchange Agent may, nevertheless, on behalf of
W&T, retain the tendered Existing Notes, without prejudice to the rights of W&T described under “—Early Participation Date; Expiration Date; Extensions; Amendments; Termination,” and “—Conditions to the Exchange
Offer” above and “—Withdrawal of Tenders” below, but subject to Rule 14e-1 under the Exchange Act, which requires that W&T pay the consideration offered or return the Existing Notes tendered promptly after the termination or
withdrawal of the Exchange Offer, and the tendered Existing Notes may not be withdrawn. 
 Under no circumstances will any interest be
payable because of any delay by the Exchange Agent or DTC in the transmission of funds to the Eligible Holders of accepted Notes or otherwise. 

Procedures for Tendering 
 The tender for
exchange by an Eligible Holder (and the subsequent acceptance of such tender by the Company) pursuant to one of the procedures set forth below will constitute a binding agreement between the Eligible Holder and the Company in accordance with the
terms and subject to the conditions set forth herein and in the letter of transmittal. 
 The Company believes that, as of the date of this
offering memorandum, all Eligible Holders hold their Existing Notes through accounts with DTC, Euroclear or Clearstream (collectively, the “Clearing Systems”) and that no Existing Notes are held in physical definitive form. Eligible
Holders who hold Existing Notes through the Clearing Systems must tender for exchange Existing Notes through the relevant Clearing System procedures. Beneficial owners whose Existing Notes are held through a broker, dealer, commercial bank, trust
company or other nominee must contact such broker, dealer, commercial bank, trust company or other nominee if they wish to tender their Existing Notes. Eligible Holders should be aware that their broker, dealer, commercial bank, trust company or
other nominee may establish its own earlier deadline for participation in the Exchange Offer. Accordingly, Eligible Holders wishing to participate in the Exchange Offer should contact their broker, dealer, commercial bank, trust company or other
nominee as soon as possible in order to determine the time by which such Eligible Holder must take action in order to so participate. 
 Existing
Notes Held through DTC 
 Custodial entities that are participants in DTC, other than DTC participants which are acting as custodians
for Existing Notes held through Euroclear or Clearstream, must tender Existing Notes for exchange through DTC’s ATOP system the rules of which the custodial entity and the beneficial owner on whose behalf the custodial entity is acting, agree
to be bound. In accordance with ATOP procedures, DTC will then verify the acceptance of the Exchange Offer and send an Agent’s Message to the Exchange Agent. An “Agent’s Message” is a message transmitted by DTC, received by the
Exchange Agent and forming part of the book-entry confirmation, which states that DTC has received an express acknowledgement from the Eligible Holder that it has (i) received the Exchange Offer, (ii) will abide by the terms of the Exchange Offer
and the letter of transmittal, and (iii) has made the confirmations or affirmations that are set forth in this offering memorandum and the letter of transmittal. 

If an Eligible Holder of Existing Notes transmits its acceptance of this Exchange Offer through ATOP, delivery of an Agent’s Message must
be timely received by the Exchange Agent. If you desire to tender your Existing Notes by the Expiration Date or, in order to receive the Early Tender Premium, on or prior to the Early Participation Date, you must allow sufficient time for completion
of the ATOP procedures during the normal business hours of DTC on or prior to the Expiration Date or the Early Participation Date, as the case may be. The Company will have the right, which may be waived, to reject the defective tender of Existing
Notes as invalid and ineffective. 

  
 A-19 

 Existing Notes Held through Participants of Euroclear and Clearstream 

Custodial entities that are participants of Euroclear and Clearstream, and which desire to tender Existing Notes for exchange held directly or
indirectly at one of such Clearing Systems, must instruct either Euroclear or Clearstream (as applicable) to block the Existing Notes in their account and transmit a notice of acceptance in respect of the Exchange Offer with respect to the tendered
Existing Notes, which must include a confirmation of blocking and an express acknowledgement from the Eligible Holder that such Eligible Holder has (i) received the Exchange Offer, (ii) will abide by the terms of the Exchange Offer and the letter of
transmittal, and (iii) has made the confirmations or affirmations which are set forth in this offering memorandum or the letter of transmittal. Such notice of acceptance (including a confirmation of blocking) must be timely received by the Exchange
Agent from Euroclear or Clearstream (or via their respective U.S. DTC custodians) via an appropriate SWIFT message or via DTC’s ATOP prior to the Expiration Date or, in order to receive the Early Tender Premium, on or prior to the Early
Participation Date. 
 Eligible Holders of Existing Notes held via Euroclear or Clearstream who are not direct participants of Euroclear or
Clearstream must contact their custodian to arrange for their direct participants in the relevant Clearing System through which they hold Existing Notes to submit the electronic acceptance and to give instruction to the relevant Clearing System to
block the relevant Existing Notes in accordance with the procedures of the relevant Clearing System and the deadlines required by the relevant Clearing System. 

Euroclear or Clearstream may impose additional deadlines in order to properly process tender instructions. As part of tendering Existing Notes
through Euroclear or Clearstream, you should be aware of and comply with any such deadlines. 
 The Exchange Agent and DTC have confirmed
that the Exchange Offer is eligible for ATOP with respect to book-entry Existing Notes held through DTC. An Agent’s Message must be transmitted to and received by the Exchange Agent prior to the Expiration Date or, in order to receive the Early
Tender Premium, on or prior to the Early Participation Date with respect to Existing Notes held via DTC. Existing Notes will not be deemed to have been tendered for exchange via DTC until an Agent’s Message, is received by the Exchange Agent

 ELIGIBLE HOLDERS OF THE EXISTING NOTES SHOULD NOTE THAT EACH OF DTC, EUROCLEAR OR CLEARSTREAM IMPOSES DAILY DEADLINES FOR THE
SUBMISSION OF ELECTRONIC INSTRUCTIONS. ACCORDINGLY, ELIGIBLE HOLDERS OF EXISTING NOTES WISHING TO PARTICIPATE IN THE EXCHANGE OFFER ARE ADVISED TO ENSURE THAT THEY SUBMIT, OR ARRANGE TO HAVE SUBMITTED ON THEIR BEHALF, ANY ELECTRONIC INSTRUCTION IN
ADVANCE OF SUCH DEADLINES IMPOSED BY DTC, EUROCLEAR OR CLEARSTREAM, AS THE CASE MAY BE. IN ADDITION, ELIGIBLE HOLDERS OF EXISTING NOTES SHOULD CHECK WITH THE BANK, SECURITIES BROKER OR ANY OTHER INTERMEDIARY THROUGH WHICH THEY HOLD THEIR EXISTING
NOTES WHETHER SUCH INTERMEDIARY APPLIES DIFFERENT DEADLINES TO PARTICIPATE IN THE EXCHANGE OFFER THAN SET OUT IN THIS OFFERING MEMORANDUM OR, AS THE CASE MAY BE, AS IMPOSED BY DTC, EUROCLEAR OR CLEARSTREAM, AS APPLICABLE, AND THEN SHOULD FOLLOW
THOSE DEADLINES. 

  
 A-20 

 All questions as to the validity, form, eligibility, including time of receipt, and acceptance
and withdrawal of tendered Notes will be determined by us in our absolute discretion, which determination will be final and binding. We reserve the absolute right to reject any and all tendered Notes determined by us not to be in proper form or not
to be tendered properly or any tendered Notes our acceptance of which would, in the opinion of our counsel, be unlawful. We also reserve the right to waive, in our absolute discretion, any defects, irregularities or conditions of tender as to
particular Notes, whether or not waived in the case of other Notes. Our interpretation of the terms and conditions of the Exchange Offer, including the terms and instructions in the letter of transmittal, will be final and binding on all parties.
Unless waived, any defects or irregularities in connection with tenders of Existing Notes must be cured within the time we determine. Although we intend to notify Eligible Holders of defects or irregularities with respect to tenders of Existing
Notes, none of W&T, the Exchange Agent, the Information Agent, the Dealer Manager or any other person will be under any duty to give that notification or shall incur any liability for failure to give that notification. Tenders of Existing Notes
with respect to such Existing Notes will not be deemed to have been made until any defects or irregularities therein have been cured or waived. 

Any Eligible Holder whose Notes have been mutilated, lost, stolen or destroyed will be responsible for obtaining replacement securities or for
arranging for indemnification with the trustee of the Existing Notes. Eligible Holders may contact the Information Agent for assistance with these matters. 

Withdrawal of Tenders 
 Tenders of
Existing Notes in the Exchange Offer may be validly withdrawn at any time on or prior to the Withdrawal Deadline, but will thereafter be irrevocable, even if we otherwise extend the Early Participation Date or extend the Exchange Offer beyond the
Expiration Date, except in certain limited circumstances where additional withdrawal rights are required by law. Tenders submitted in the Exchange Offer after the Withdrawal Deadline will be irrevocable except in the limited circumstances where
additional withdrawal rights are required by law. 
 To be effective, a notice of withdrawal must be received by the Exchange Agent through
ATOP (or analogous procedures of either Euroclear or Clearstream), in each case not later than the Withdrawal Deadline. 
 This notice must
specify: 
  

	 	•	 	the name of the person or entity having tendered the Existing Notes to be withdrawn; and 

  

	 	•	 	the Existing Notes to be withdrawn including the name and the participant account number of the participant entity at either DTC, Euroclear or Clearstream to be credited with the withdrawn Notes. 

Eligible Holders of the Existing Notes are advised to inform themselves with the bank, securities broker or any other intermediary through which they hold
their Existing Notes whether such intermediary would require receiving instructions to participate in, or withdraw their instruction to participate in, the Exchange Offer prior to the deadlines set out in this offering memorandum. 

We will make a final and binding determination on all questions as to the validity, form and eligibility (including time of receipt) of such
notices. Any Existing Notes so withdrawn will be deemed not to have been validly tendered for exchange for the purposes of the Exchange Offer. Any Existing Notes tendered for exchange but not exchanged for any reason will be released to the Eligible
Holder pursuant to the book-entry transfer procedures described above and such Existing Notes will be credited to an account maintained with the relevant Clearing System for the Existing Notes promptly after withdrawal, rejection of tender or
termination of the Exchange Offer. 

  
 A-21 

 Withdrawal of tenders of Existing Notes may not be rescinded, and any Existing Notes validly
withdrawn will thereafter be deemed not to have been validly tendered for purposes of the Exchange Offer. Validly withdrawn Existing Notes may, however, be re-tendered by again following one of the procedures described in “—Procedures for
Tendering” above prior to the Expiration Date or, in order to receive the Early Tender Premium, on or prior to the Early Participation Date. 

Exchange Agent; Information Agent 
 D.F.
King has been appointed as the Exchange Agent and the Information Agent for the Exchange Offer. All correspondence in connection with the Exchange Offer should be sent or delivered by each Eligible Holder of Existing Notes, or a beneficial
owner’s commercial bank, broker, dealer, trust company or other nominee, to the Exchange Agent at the address listed on the back cover of this offering memorandum. Questions concerning tender procedures and requests for additional copies of
this offering memorandum or the letter of transmittal should be directed to the Information Agent at the address and telephone numbers listed on the back cover of this offering memorandum. The eligibility certification and copies of this offering
memorandum and the related letter of transmittal are available at www.dfking.com/[●]. Eligible Holders of Existing Notes may also contact their commercial bank, broker, dealer, trust company or other nominee
for assistance concerning the Exchange Offer. We will pay the Exchange Agent and the Information Agent reasonable and customary fees for its services and will reimburse it for its reasonable out-of-pocket expenses. 

Dealer Manager 
 In connection with the
Exchange Offer, we have retained Evercore Group L.L.C. as the Dealer Manager. We will pay a customary fee to the Dealer Manager for soliciting acceptances of the Exchange Offer. That fee will be payable upon completion of the Exchange Offer. 

The obligations of the Dealer Manager to perform its functions are subject to various conditions. We have agreed to indemnify the Dealer
Manager against various liabilities, including various liabilities under the federal securities laws. The Dealer Manager may contact Eligible Holders of Existing Notes by mail, telephone, facsimile transmission, personal interviews and otherwise may
request broker dealers and the other nominee holders to forward materials relating to the Exchange Offer to beneficial holders. Questions regarding the terms of the Exchange Offer may be directed to each Dealer Manager at its address and telephone
number listed on the back cover of this offering memorandum. At any given time, the Dealer Manager may trade the Existing Notes or other of our securities for its own accounts or for the accounts of its customers and, accordingly, may hold a long or
short position in the Existing Notes. 
 The Dealer Manager has, from time to time, provided and/or is currently providing investment
banking and financial advisory services to us and our affiliates. The Dealer Manager may in the future provide various investment banking and other services to us, and our affiliates, for which it would receive customary compensation from us. 

In the ordinary course of its business, the Dealer Manager or its affiliates may at any time hold long or short positions, and may trade for
its own account or the accounts of customers, in debt or equity securities issued by us and our subsidiaries and affiliates, including any of the Existing Notes, the Shares, the New Second Lien Notes or the New Unsecured Notes. To the extent that
the Dealer Manager or its affiliates own Existing Notes during the Exchange Offer, they may tender such Existing Notes pursuant to the terms of the Exchange Offer. The Dealer Manager and its affiliates may from time to time in the future engage in
transactions with us and our subsidiaries and affiliates and provide services to them in the ordinary course of their respective businesses. 

  
 A-22 

 In connection with the Exchange Offer or otherwise, the Dealer Manager may purchase and sell
Existing Notes, the Shares, the New Second Lien Notes or the New Unsecured Notes in the open market. These transactions may include covering transactions and stabilizing transactions. Any of these transactions may have the effect of preventing or
retarding a decline in the market prices of the Existing Notes, the Shares, the New Second Lien Notes and/or the New Unsecured Notes. They may also cause the prices of the Existing Notes, the Shares, the New Second Lien Notes and/or the New
Unsecured Notes to be higher than the prices that otherwise would exist in the open market in the absence of these transactions. The Dealer Manager may conduct these transactions in the over-the-counter market or otherwise. If the Dealer Manager
commences any of these transactions, it may discontinue them at any time. 
 Other Fees and Expenses 

We will bear the expenses of soliciting tenders of the Existing Notes. Solicitations of Eligible Holders may be made by mail, e-mail, facsimile
transmission, telephone or in person by the Dealer Manager, Information Agent, Exchange Agent as well as by our officers and other employees and those of our affiliates. No additional compensation will be paid to any officers or employees who engage
in soliciting exchanges. 
 Tendering Eligible Holders of Existing Notes accepted in the Exchange Offer will not be obligated to pay
brokerage commissions or fees to us, the Dealer Manager, the Exchange Agent or the Information Agent or, except as set forth below, to pay transfer taxes with respect to the exchange of their Existing Notes. If, however, a tendering Eligible Holder
handles the transaction through its broker, dealer, commercial bank, trust company or other institution that Eligible Holder may be required to pay brokerage fees or commissions. 

Transfer Taxes 
 You will not be obligated
to pay any transfer taxes in connection with the tender of Existing Notes in the Exchange Offer unless you instruct us to cause the issuance of Shares, New Second Lien Notes or the New Unsecured Notes, or request that Existing Notes not tendered or
accepted in the Exchange Offer be returned, to a person other than the tendering Eligible Holder. In those cases, you will be responsible for the payment of any applicable transfer taxes. 

NONE OF W&T, THE DEALER MANAGER, THE TRUSTEE WITH RESPECT TO THE EXISTING NOTES, THE NEW SECOND LIEN NOTES AND THE NEW UNSECURED NOTES, THE EXCHANGE
AGENT, THE INFORMATION AGENT, AND ANY AFFILIATE OF ANY OF THEM, MAKES ANY RECOMMENDATION AS TO WHETHER ELIGIBLE HOLDERS OF THE EXISTING NOTES SHOULD EXCHANGE THEIR EXISTING NOTES FOR SHARES, NEW SECOND LIEN NOTES AND NEW UNSECURED NOTES IN RESPONSE
TO THE EXCHANGE OFFER.

clause (6)(c)(4) under “Conditions to Closing” below, to the extent any security interest in the collateral is not or cannot be perfected on the Closing Date or a filing for such perfection is not or cannot be made on the Closing Date
(other than the perfection of collateral or filings for perfection of collateral with respect to which a lien may be perfected by the filing of financing statements under the Uniform Commercial Code (“UCC”) in the relevant

additional Shares paid, issued or distributed in respect of any such Shares by way of a stock dividend, stock split or distribution, or in connection with a combination of Shares and (c) any additional Shares acquired by any Holder in open market or
other purchases; provided, however, that as to any Registrable Securities, such securities shall cease to constitute Registrable Securities when (i) a registration statement covering such Registrable Security becomes or has been
declared effective by the Commission and such Registrable Security has been sold or disposed of pursuant to such effective registration statement; (ii) such Registrable Security has been disposed of pursuant to Rule 144 (or any similar provision
then in effect) under the Securities Act of 1933, as amended (the “Securities Act”); (iii) such Registrable Security is held by the Company or one of its subsidiaries or Affiliates; (iv) such Registrable Security has been sold or

	 Initial Shelf
 Registration Statement
	 	 The Company will file a shelf registration statement on Form S-1 (or Form S-3, if available) (the “Initial Shelf Registration
Statement”) with the Securities and Exchange Commission (the “Commission”) on or prior to the 45th day following the date of the Agreement.

 
 The Company will use its commercially reasonable efforts to cause the Initial Shelf
Registration Statement to be declared effective by the Commission, supplemented and amended to the extent necessary to ensure that it is available for the resale of all Registrable Securities by the Holders until all Registrable Securities covered
by such Initial Shelf Registration Statement have ceased to be Registrable Securities (the “Effectiveness Period”).
  

If the Initial Shelf Registration Statement shall be unavailable after its initial effective date, for so long as any Registrable Securities remain
outstanding, the Company will use its commercially reasonable efforts to register the Registrable Securities on another registration statement (each such registration statement under the Agreement and the Initial Shelf Registration Statement, a
“Registration Statement”), (ii) use its commercially reasonable efforts to cause any such registration statement to be declared effective by the Commission and (iii) use its commercially reasonable efforts to keep such other

misleading (in the case of any prospectus contained in such Registration Statement or documents incorporated therein by reference, in the light of the circumstances under which a statement is made). As soon as practicable following the date that any
Registration Statement becomes effective, but in any event within two (2) Business Days of such date, the Company shall provide the Holders with notice of the effectiveness of such registration statement.

executive officer and its Chief Financial Officer and/or Chief Accounting Officer to attend and participate in “road shows” and other information meetings organized by the underwriters, if any, as reasonably requested; provided, that the
Company will have no obligation to participate in more than two (2) “road shows” in any twelve (12)-month period and such participation will not unreasonably interfere with the business operations of the Company.

		
	Grace Periods	 	After a Registration Statement has been declared effective by the Commission, the Company may, upon written notice to any Holder whose Registrable Securities are included in such registration statement, postpone the filing or
effectiveness of, or suspend the use of, a registration statement if, in the Company’s good faith determination, such use would (a) materially interfere with a significant acquisition, reorganization, financing or other similar transaction
involving the Company, (b) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential and the Company may delay the disclosure of such material non-public information or (c)
render the Company unable to comply with applicable

365-day period, in each case, exclusive of days covered by any lock-up agreement executed by a Holder in connection with an Underwritten Offering. Upon disclosure of such information or the termination of the condition described above, the
Company shall provide prompt notice to the Holders whose Registrable Securities are included in such Registration Statement, and shall promptly terminate any suspension of sales it has put into effect and shall take such other reasonable actions to
permit registered sales of Registrable Securities as contemplated by the Agreement.
		
	Lock Up Provisions	 	Each Holder will agree, if requested by the underwriters of an Underwritten Offering, to enter into a customary lock-up agreement with such underwriter(s) in connection with such Underwritten Offering providing such Holder will not
effect any public sale or distribution of Registrable Securities during an otherwise agreed to period beginning on the date of a prospectus or prospectus supplement filed with the Commission with respect to the pricing of such Underwritten Offering,
provided that the duration of such restriction shall be no longer than the duration of the shortest restriction generally imposed by such underwriter(s) on the Company or the officers, directors or any other Affiliate of the Company on whom a
restriction is imposed and the restrictions of such lock-up agreement shall not apply to any Registrable Securities that are included in such Underwritten Offering by such Holder.
		
	Rule 144A Reporting	 	The Company agrees to use commercially reasonable efforts to make customary efforts, including to make and keep public information regarding the Company available and make such filings of reports and other documents and furnish such
reports to Holders, for the purpose of permitting the sale of the Registrable Securities to the public without registration.

 Registration Rights
	 	Any Holder may freely assign its rights under the Agreement with respect to any Registrable Securities in connection with any transfer of such Registrable Securities, subject to certain customary conditions, provided that (a) the

assigned, (b) each such transferee or assignee assumes in writing responsibility for its portion of the obligations of such original Holder under the Agreement, (c) the transferor or assignor is not relieved of any obligations or liabilities under
the Agreement arising out of events occurring prior to such transfer, and (d) following the completion of such assignment, the assignee will hold at least 1% of the outstanding Shares.
		
	Fees and Expenses	 	The Company will pay all reasonable expenses incident to the Company’s performance under or compliance with the Agreement to effect the registration of the Registrable Securities, including, in the case of an Underwritten
Offering, whether or not any sale is made pursuant to such Underwritten Offering, including all reasonable fees and disbursements of one legal counsel to the Holders retained in connection with any Underwritten Offering by the
Holders

	 Limitation on
 Subsequent

or future holder to require the Company to include securities in any registration statement filed by the Company on a basis other than pari passu with, or expressly subordinate to the rights of, the Holders of Registrable Securities under the
Agreement.
