Subject to and effective upon the acceptance for exchange of all or any portion of the September 2018 Notes tendered herewith, in accordance with the terms and conditions of the offer by Diamondback Energy, Inc., a Delaware corporation (the “Company”), to exchange (the “Exchange Offer”) up to $750,000,000 of its 4.750% Senior Notes due 2024, which have been registered under the Securities Act of 1933, as amended (the “Securities Act”), for an equal principal amount of its 4.750% Senior Notes due 2024 (the “September 2018 Notes”), issued in a private offering on September 25, 2018, including, if the Exchange Offer is extended or amended, the terms and conditions of any such extension or amendment, the undersigned hereby sells, assigns and transfers to or upon the order of the Company all right, title and interest in and to such September 2018 Notes as is being tendered herewith. The undersigned hereby irrevocably constitutes and appoints the Exchange Agent as its agent and attorney-in-fact (with full knowledge that the Exchange Agent is also acting as agent of the Company in connection with the Exchange Offer) with respect to the tendered September 2018 Notes, with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest) subject only to the right of withdrawal described in the Prospectus, to (i) deliver certificates for September 2018 Notes (“Certificates”) to the Company together with all accompanying evidences of transfer and authenticity to, or upon the order of, the Company, upon receipt by the Exchange Agent, as the undersigned’s agent, of the Exchange Notes to be issued in exchange for such September 2018 Notes, (ii) present Certificates for such September 2018 Notes for transfer, and to transfer the September 2018 Notes on the books of the Company, and (iii) receive for the account of the Company all benefits and otherwise exercise all rights of beneficial ownership of such September 2018 Notes, all in accordance with the terms and conditions of the Exchange Offer.

The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, exchange, sell, assign and transfer the September 2018 Notes tendered hereby and that, when the same is accepted for exchange, the Company will acquire good, marketable and unencumbered title thereto, free and clear of all liens, restrictions, charges and encumbrances, and that the September 2018 Notes tendered hereby are not subject to any adverse claims or proxies. The undersigned will, upon request, execute and deliver any additional documents deemed by the Company or the Exchange Agent to be necessary or desirable to complete the exchange, assignment and transfer of the September 2018 Notes tendered hereby, and the undersigned will comply with its obligations under the Registration Rights Agreement, dated as of September 25, 2018, relating to the September 2018 Notes (the “Registration Rights Agreement”). The undersigned has read and agrees to all of the terms of the Exchange Offer.

The name(s) and address(es) of the registered Holder(s) of the September 2018 Notes tendered hereby should be printed above, if they are not already set forth above, as they appear on the Certificates representing such September 2018 Notes. The Certificate number(s) and the September 2018 Notes that the undersigned wishes to tender should be indicated in the appropriate boxes above.

If any tendered September 2018 Notes are not exchanged pursuant to the Exchange Offer for any reason, or if Certificates are submitted for more September 2018 Notes than are tendered or accepted for exchange, Certificates for such non-exchanged or non-tendered September 2018 Notes will be returned (or, in the case of September 2018 Notes tendered by book-entry transfer, such September 2018 Notes will be credited to an account maintained at DTC), without expense to the tendering Holder, promptly following the expiration or termination of the Exchange Offer.

The undersigned understands that tenders of September 2018 Notes pursuant to any one of the procedures described in “The Exchange Offer—Procedures for Tendering September 2018 Notes” in the Prospectus and in the instructions attached hereto will, upon the Company’s acceptance for exchange of such tendered September 2018 Notes, constitute a binding agreement between the undersigned and the Company upon the terms and subject to the conditions of the Exchange Offer. The undersigned recognizes that, under certain circumstances set forth in the Prospectus, the Company may not be required to accept for exchange any of the September 2018 Notes tendered hereby.

Unless otherwise indicated herein in the box entitled “Special Issuance Instructions” below, the undersigned hereby directs that the Exchange Notes be issued in the name(s) of the undersigned or, in the case of a book-entry transfer of September 2018 Notes, that such Exchange Notes be credited to the account indicated above maintained at DTC. If applicable, substitute Certificates representing September 2018 Notes not exchanged or not accepted for exchange will be issued to the undersigned or, in the case of a book-entry transfer of September 2018 Notes, will be credited to the account indicated above maintained at DTC. Similarly, unless otherwise indicated under “Special Delivery Instructions,” please deliver Exchange Notes to the undersigned at the address shown below the undersigned’s signature.

By tendering September 2018 Notes and executing this Letter of Transmittal or effecting delivery of an Agent’s Message in lieu thereof, the undersigned hereby represents and agrees that (i) the undersigned is not an “affiliate” of the Company, (ii) any Exchange Notes to be received by the undersigned are being acquired in the ordinary course of its business, (iii) the undersigned has no arrangement or understanding with any person to participate in a distribution (within the meaning of the Securities Act) of Exchange Notes to be received in the Exchange Offer, and (iv) if the undersigned is not a broker-dealer, the undersigned is not engaged in, and does not intend to engage in, a distribution (within the meaning of the Securities Act) of such Exchange Notes.

The Company may require the undersigned, as a condition to the undersigned’s eligibility to participate in the Exchange Offer, to furnish to the Company (or an agent thereof) in writing information as to the number of “beneficial owners” within the meaning of Rule 13d-3 under the Exchange Act on behalf of whom the undersigned holds the September 2018 Notes to be exchanged in the Exchange Offer. If the undersigned is a broker-dealer that will receive Exchange Notes for its own account in exchange for September 2018 Notes, it represents that the September 2018 Notes to be exchanged for Exchange Notes were acquired by it as a result of market-making activities or other trading activities and acknowledges that it will deliver a Prospectus in connection with any resale of such Exchange Notes; however, by so acknowledging and by delivering a Prospectus, the undersigned will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

The Company has agreed that, subject to the provisions of the Registration Rights Agreement, the Prospectus, as it may be amended or supplemented from time to time, may be used by a Participating Broker-Dealer (as defined below) in connection with resales of Exchange Notes received in exchange for September 2018 Notes, where such September 2018 Notes were acquired by such Participating Broker-Dealer for its own account as a result of market-making activities or other trading activities, for a period ending 12 months after the effective date of the registration statement relating to the Exchange Notes (the “Effective Date”) (subject to extension under certain limited circumstances described in the Prospectus) or, if earlier, when all such Exchange Notes have been disposed of by such Participating Broker-Dealer. In that regard, each broker-dealer who acquired September 2018 Notes for its own account as a result of market-making or other trading activities (a “Participating Broker-Dealer”), by tendering such September 2018 Notes and executing this Letter of Transmittal or effecting delivery of an Agent’s Message in lieu thereof, agrees that, upon receipt of notice from the Company of the occurrence of any event or the discovery of any fact which makes any statement contained or incorporated by reference in the Prospectus untrue in any material respect or which causes the Prospectus to omit to state a material fact necessary in order to make the statements contained or incorporated by reference therein, in light of the circumstances under which they were made, not misleading or of the occurrence of certain other events specified in the Registration Rights Agreement relating to the September 2018 Notes, such Participating Broker-Dealer will suspend the sale of Exchange Notes pursuant to the Prospectus until the Company has amended or supplemented the Prospectus to correct such misstatement or omission and has furnished copies of the amended or supplemented Prospectus to the Participating Broker-Dealer or the Company has given notice that the sale of the Exchange Notes may be resumed, as the case may be. If the Company gives such notice to suspend the sale of the Exchange Notes, it shall extend the 12-month period referred to above during which Participating Broker-Dealers are entitled to use the Prospectus in connection with the resale of Exchange Notes by the number of days during the period from and including the date of the giving of such notice to and including the date when Participating Broker-Dealers shall have received copies of the supplemented or amended Prospectus necessary to permit resales of the Exchange Notes or to and including the date on which the Company has given notice that the sale of Exchange Notes may be resumed, as the case may be.

As a result, a Participating Broker-Dealer who intends to use the Prospectus in connection with resales of Exchange Notes received in exchange for September 2018 Notes pursuant to the Exchange Offer must notify the Company, or cause the Company to be notified, on or prior to the Expiration Date, that it is a Participating Broker-Dealer. Such notice may be given in the space provided above or may be delivered to the Exchange Agent at the address set forth in the Prospectus under “The Exchange Offer—Exchange Agent.”

The undersigned will, upon request, execute and deliver any additional documents deemed by the Company to be necessary or desirable to complete the sale, assignment and transfer of the September 2018 Notes tendered hereby. All authority herein conferred or agreed to be conferred in this Letter of Transmittal shall survive the death or incapacity of the undersigned and any obligation of the undersigned hereunder shall be binding upon the heirs, executors, administrators, personal representatives, trustees in bankruptcy, legal representatives, successors and assigns of the undersigned. Except as stated in the Prospectus, this tender is irrevocable.

The undersigned, by completing the box entitled “Description of September 2018 Notes” above and signing this letter, will be deemed to have tendered the September 2018 Notes as set forth in such box.

In all cases, sufficient time should be allowed to ensure timely delivery.

The Company will not accept any alternative, conditional or contingent tenders. Each tendering Holder, by execution of a Letter of Transmittal (or facsimile thereof), waives any right to receive any notice of the acceptance of such tender.

2. Guarantee of Signatures. No signature guarantee on this Letter of Transmittal is required if:

i. this Letter of Transmittal is signed by the registered Holder (which term, for purposes of this document, shall include any participant in DTC whose name appears on a security position listing as the owner of the September 2018 Notes (the “Holder”)) of September 2018 Notes tendered herewith, unless such Holder(s) has completed either the box entitled “Special Issuance Instructions” or the box entitled “Special Delivery Instructions” above, or

ii. such September 2018 Notes are tendered for the account of a firm that is an Eligible Institution.

In all other cases, an Eligible Institution must guarantee the signature(s) on this Letter of Transmittal. See Instruction 5.

4. Partial Tenders and Withdrawal Rights. Tenders of September 2018 Notes will be accepted only in principal amounts equal to $2,000 or integral multiples of $1,000 in excess thereof. If less than all the September 2018 Notes evidenced by any Certificate submitted are to be tendered, fill in the principal amount of September 2018 Notes which are to be tendered in the box entitled “Principal Amount of September 2018 Notes Tendered.” In such case, new Certificate(s) for the remainder of the September 2018 Notes that were evidenced by your old Certificate(s) will only be sent to the Holder of the September 2018 Notes, promptly after the Expiration Date. All September 2018 Notes represented by Certificates delivered to the Exchange Agent will be deemed to have been tendered unless otherwise indicated.

Except as otherwise provided herein, tenders of September 2018 Notes may be withdrawn at any time on or prior to the Expiration Date. In order for a withdrawal to be effective on or prior to that time, a written or facsimile transmission of such notice of withdrawal must be timely received by the Exchange Agent at its address set forth above and in the Prospectus, or you must comply with the appropriate procedures of DTC’s automated tender offer program, in each case on or prior to the Expiration Date. Any such notice of withdrawal must specify the name of the person who tendered the September 2018 Notes to be withdrawn, the aggregate principal amount of the September 2018 Notes to be withdrawn, and (if Certificates for September 2018 Notes have been tendered) the name of the registered Holder of the September 2018 Notes as set forth on the Certificate for the September 2018 Notes, if different from that of the person who tendered such September 2018 Notes.

If Certificates for the September 2018 Notes have been delivered or otherwise identified to the Exchange Agent, then prior to the physical release of such Certificates for the September 2018 Notes, the tendering Holder must submit the serial numbers shown on the particular Certificates for the September 2018 Notes to be withdrawn and the signature on the notice of withdrawal must be guaranteed by an Eligible Institution, except in the case of September 2018 Notes tendered for the account of an Eligible Institution.

Withdrawals of tenders of September 2018 Notes may not be rescinded. September 2018 Notes properly withdrawn will not be deemed validly tendered for purposes of the Exchange Offer, but may be retendered at any subsequent time on or prior to the Expiration Date by following any of the procedures described in the Prospectus under “The Exchange Offer—Procedures for Tendering September 2018 Notes.”

All questions as to the validity, form and eligibility (including time of receipt) of such withdrawal notices will be determined by the Company, in its sole discretion, whose determination shall be final and binding on all parties. The Company, any affiliates or assigns of the Company, the Exchange Agent or any other person shall not be under any duty to give any notification of any irregularities in any notice of withdrawal or incur any liability for failure to give any such notification. Any September 2018 Notes that have been tendered but that are withdrawn will be returned to the Holder thereof without cost to such Holder promptly after withdrawal.

5. Signatures on Letter of Transmittal, Assignments and Endorsements. If this Letter of Transmittal is signed by the registered Holder(s) of the September 2018 Notes tendered hereby, the signature(s) must correspond exactly with the name(s) as written on the face of the Certificate(s) without alteration, enlargement or any change whatsoever.

If any September 2018 Notes tendered hereby are owned of record by two or more joint owners, all such owners must sign this Letter of Transmittal.

If any tendered September 2018 Notes are registered in different name(s) on several Certificates, it will be necessary to complete, sign and submit as many separate Letters of Transmittal (or facsimiles thereof) as there are different registrations of Certificates.

If this Letter of Transmittal or any Certificates or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing and, unless waived by the Company, must submit proper evidence satisfactory to the Company, in its sole discretion, of each such person’s authority to so act.

When this Letter of Transmittal is signed by the registered owner(s) of the September 2018 Notes listed and transmitted hereby, no endorsement(s) of Certificate(s) or separate bond power(s) is required unless Exchange Notes are to be issued in the name of a person other than the registered Holder(s), or Exchange Notes or September 2018 Notes not tendered are to be sent to someone other than the registered Holder(s) or to an address other than that of the registered Holder(s). Signature(s) on such Certificate(s) or bond power(s) must be guaranteed by an Eligible Institution.

If this Letter of Transmittal is signed by a person other than the registered owner(s) of the September 2018 Notes listed, the Certificates must be endorsed or accompanied by appropriate bond powers, signed exactly as the name or names of the registered owner(s) appear(s) on the Certificates, and also must be accompanied by such opinions of counsel, certifications and other information as the Company or the Trustee for the September 2018 Notes may require in accordance with the restrictions on transfer applicable to the September 2018 Notes. Signatures on such Certificates or bond powers must be guaranteed by an Eligible Institution.

6. Special Issuance and Delivery Instructions. If Exchange Notes are to be issued in the name of a person other than the signer of this Letter of Transmittal, or if Exchange Notes are to be sent to someone other than the signer of this Letter of Transmittal or to an address other than that shown above, the appropriate boxes on this Letter of Transmittal should be completed. Certificates for September 2018 Notes not exchanged will be returned by mail or, if tendered by book-entry transfer, by crediting the account indicated above maintained at DTC. See Instruction 4.

7. Irregularities. The Company will determine, in its sole discretion, all questions as to the form of documents, validity, eligibility (including time of receipt) and acceptance for exchange of any tender of September 2018 Notes, which determination shall be final and binding on all parties. The Company reserves the absolute right to reject any and all tenders determined by it not to be in proper form or the acceptance of which, or exchange for which may, in the view of counsel to the Company be unlawful. The Company also reserves the absolute right, subject to applicable law, to waive any of the conditions of the Exchange Offer set forth in the Prospectus under “The Exchange Offer—Conditions to the Exchange Offer” or any conditions or irregularities in any tender of September 2018 Notes of any particular Holder whether or not similar conditions or irregularities are waived in the case of other Holders. The Company’s interpretation of the terms and conditions of the Exchange Offer (including this Letter of Transmittal

and the instructions hereto) will be final and binding. No tender of September 2018 Notes will be deemed to have been validly made until all irregularities with respect to such tender have been cured or waived. The Company, any affiliates or assigns of the Company, the Exchange Agent, or any other person shall not be under any duty to give notification of any irregularities in tenders or incur any liability for failure to give such notification.

8. Questions, Requests for Assistance and Additional Copies. Questions and requests for assistance may be directed to the Exchange Agent at its address and telephone number set forth on the front of this Letter of Transmittal. When contacting the Exchange Agent, please refer to the CUSIP/ISIN number(s) of the September 2018 Notes. Additional copies of the Prospectus and the Letter of Transmittal may be obtained from the Exchange Agent or from your broker, dealer, commercial bank, trust company or other nominee.

9. Backup Withholding; IRS Form W-9.

Under the U.S. federal income tax law, a Holder whose tendered September 2018 Notes are accepted for exchange is required to provide the Exchange Agent with such Holder’s correct taxpayer identification number (“TIN”). The Holder’s TIN must be provided on an IRS Form W-9, furnished below. If the Exchange Agent is not provided with the correct TIN, payments to such Holders or other payees with respect to September 2018 Notes exchanged pursuant to the Exchange Offer may be subject to 24% backup withholding. Additionally, a $50 penalty may be imposed on the Holder by the Internal Revenue Service (“IRS”) if a TIN is not provided. Failure to comply truthfully with the backup withholding requirements also may result in the imposition of severe criminal and/or civil fines and penalties.

Certain Holders (including, among others, all corporations and certain non-U.S. persons) are not subject to these backup withholding requirements. Exempt Holders (other than non-U.S. persons) should furnish their TIN, complete the certification in Part II of the Form W-9, and sign, date and return the Form W-9 to the Exchange Agent’s address provided herein. A non-U.S. person, including an entity, may qualify as an exempt recipient by submitting an appropriate, properly completed Internal Revenue Service Form W-8BEN, W-8BEN-E, W-8ECI, W-8EXP or W-8IMY, as the case may be, signed under penalties of perjury, certifying to that Holder’s foreign status. An appropriate Form W-8 can be obtained via the Internal Revenue Service website at www.irs.gov. See the enclosed IRS Form W-9 for additional instructions.

A Holder should write “Applied For” in the space for the TIN provided on the attached IRS Form W-9 if the tendering Holder has not been issued a TIN and has applied for a TIN or intends to apply for a TIN in the near future. Notwithstanding that “Applied For” is written in the appropriate space on the attached IRS Form W-9, the Exchange Agent will withhold 24% of all payments made prior to the time a properly certified TIN is provided to the Exchange Agent. The Exchange Agent will retain such amounts withheld during the 60-day period following the date of the IRS Form W-9. If the Holder furnishes the Exchange Agent with its TIN within 60 days after the date of the IRS Form W-9, the amounts retained during the 60-day period will be remitted to the Holder and no further amounts shall be retained or withheld from payments made to the Holder thereafter. If, however, the Holder has not provided the Exchange Agent with its TIN within such 60-day period, amounts withheld will be remitted to the IRS as backup withholding. In addition, 24% of all payments made thereafter will be withheld and remitted to the IRS until a correct TIN is provided.

The Holder is required to provide the TIN (e.g., social security number, individual taxpayer identification number or employer identification number) of the registered Holder. If the Notes are held in more than one name or are held not in the name of the actual owner, consult the enclosed Form W-9 for additional guidance on which number to report.

Backup withholding is not an additional U.S. federal income tax. Rather, the U.S. federal income tax liability of a person subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained.

For further information concerning backup withholding and instructions for completing the IRS Form W-9 (including how to obtain a TIN if you do not have one), consult the enclosed Instructions on IRS Form W-9.

10. Waiver of Conditions. The Company reserves the absolute right to waive satisfaction of any or all conditions enumerated in the Prospectus.

11. No Conditional Tenders. No alternative, conditional or contingent tenders will be accepted. All tendering Holders of September 2018 Notes, by execution of this Letter of Transmittal, shall waive any right to receive notice of the acceptance of September 2018 Notes for exchange.

Neither the Company, the Exchange Agent nor any other person is obligated to give notice of any defect or irregularity with respect to any tender of September 2018 Notes nor shall any of them incur any liability for failure to give any such notice.

12. Lost, Destroyed or Stolen Certificates. If any Certificate(s) representing September 2018 Notes have been lost, destroyed or stolen, the Holder should promptly notify the Exchange Agent. The Holder will then be instructed as to the steps that must be taken in order to replace the Certificate(s). This Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost, destroyed or stolen Certificate(s) have been followed.

13. Transfer Taxes. Holders who tender their September 2018 Notes for exchange will not be obligated to pay any transfer taxes in connection therewith. If, however, Exchange Notes are to be delivered to, or are to be issued in the name of, any person other than the registered Holder of the September 2018 Notes tendered, or if a transfer tax is imposed for any reason other than the exchange of September 2018 Notes in connection with the Exchange Offer, then the amount of any such transfer tax (whether imposed on the registered Holder or any other persons) will be payable by the tendering Holder. If satisfactory evidence of payment of such taxes or exemption therefrom is not submitted with the Letter of Transmittal, the amount of such transfer taxes will be billed directly to such tendering Holder.
