Subject to and effective upon the acceptance for exchange of all or any portion of the 2015 Notes tendered herewith, in accordance with the terms and conditions of the offer by Gulfport Energy Corporation., a Delaware corporation (the “Company”), to exchange (the “Exchange Offer”) up to $350,000,000 of its 6.625% Senior Notes due 2023, which have been registered under the Securities Act of 1933, as amended (the “Securities Act”), for an equal principal amount of its 6.625% Senior Notes due 2023 (the “2015 Notes”), issued in private offerings on April 21, 2015, 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 2015 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 2015 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 2015 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 2015 Notes, (ii) present Certificates for such 2015 Notes for transfer, and to transfer the 2015 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 2015 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 2015 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 2015 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 2015 Notes tendered hereby, and the undersigned will comply with its obligations under the Registration Rights Agreement, dated as of April 21, 2015, relating to the 2015 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 2015 Notes tendered hereby should be printed above, if they are not already set forth above, as they appear on the Certificates representing such 2015 Notes. The Certificate number(s) and the 2015 Notes that the undersigned wishes to tender should be indicated in the appropriate boxes above.

If any tendered 2015 Notes are not exchanged pursuant to the Exchange Offer for any reason, or if Certificates are submitted for more 2015 Notes than are tendered or accepted for exchange, Certificates for such nonexchanged or nontendered 2015 Notes will be returned (or, in the case of 2015 Notes tendered by book-entry transfer, such 2015 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 2015 Notes pursuant to any one of the procedures described in “The Exchange Offer — Procedures for Tendering 2015 Notes” in the Prospectus and in the instructions attached hereto will, upon the Company’s acceptance for exchange of such tendered 2015 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 2015 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 2015 Notes, that such Exchange Notes be credited to the account indicated above maintained at DTC. If applicable, substitute Certificates representing 2015 Notes not exchanged or not accepted for exchange will be issued to the undersigned or, in the case of a book-entry transfer of 2015 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 2015 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 2015 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 2015 Notes, it represents that the 2015 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 2015 Notes, where such 2015 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 2015 Notes for its own account as a result of market-making or other trading activities (a “Participating Broker-Dealer”), by tendering such 2015 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 2015 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 2015 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 2015 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 2015 Notes” above and signing this letter, will be deemed to have tendered the 2015 Notes as set forth in such box.

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 2015 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.

9. 28% Backup Withholding; Substitute Form W-9.

U.S. INTERNAL REVENUE SERVICE CIRCULAR 230 NOTICE: TO ENSURE COMPLIANCE WITH INTERNAL REVENUE SERVICE CIRCULAR 230, HOLDERS ARE HEREBY NOTIFIED THAT: (A) ANY DISCUSSION OF U.S. FEDERAL TAX ISSUES CONTAINED OR REFERRED TO IN THIS DOCUMENT OR ANY DOCUMENT REFERRED TO HEREIN IS NOT INTENDED OR WRITTEN TO BE USED, AND CANNOT BE USED BY HOLDERS FOR THE PURPOSE OF AVOIDING PENALTIES THAT MAY BE IMPOSED ON THEM UNDER THE U.S. INTERNAL REVENUE CODE; (B) SUCH DISCUSSION IS WRITTEN FOR USE IN CONNECTION WITH THE PROMOTION OR MARKETING OF THE TRANSACTIONS OR MATTERS ADDRESSED HEREIN; AND (C) HOLDERS SHOULD SEEK ADVICE BASED ON THEIR PARTICULAR CIRCUMSTANCES FROM AN INDEPENDENT TAX ADVISOR.

Under the U.S. federal income tax law, a Holder whose tendered 2015 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 may be provided on an IRS Form W-9 or a Substitute Form W-9 as furnished below. If the Exchange Agent is not provided with the correct TIN, payments to such Holders or other payees with respect to 2015 Notes exchanged pursuant to the Exchange Offer may be subject to 28% backup withholding. In addition, the Internal Revenue Service (the “IRS”) may subject the Holder or other payee to penalties for failure to provide a valid TIN or for providing false information in connection with a request for a TIN.

A Holder should write “Applied For” in the space for the TIN provided on the attached Substitute 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. The Holder or other payee must also complete the Certificate of Awaiting Taxpayer Identification Number below in order to avoid backup withholding. Notwithstanding that “Applied For” is written in the appropriate space on the attached Substitute Form W-9 and the Certificate of Awaiting Taxpayer Identification Number is completed, the Exchange Agent will withhold 28% 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 Substitute Form W-9. If the Holder furnishes the Exchange Agent with its TIN within 60 days after the date of the Substitute 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, 28% of all payments made thereafter will be withheld and remitted to the IRS until a correct TIN is provided. A Holder who writes “Applied For” in the space in Part 1 in lieu of furnishing his or her TIN should furnish the Exchange Agent with such Holder’s TIN as soon as it is received.

A Holder is required to give the Exchange Agent the TIN (e.g., social security number or employer identification number) of the registered owner of the 2015 Notes or of the last transferee appearing on the transfers attached to, or endorsed on, the 2015 Notes. If the 2015 Notes are registered in more than one name or are not in the name of the actual owner, consult the enclosed “Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9” for additional guidance on which number to report.

Certain Holders and payees (including, among others, all corporations and certain foreign individuals) may not be subject to the backup withholding and information reporting requirements, provided that they properly demonstrate their eligibility for exemption. Such Holders should furnish their TIN, write “Exempt” in Part 2 of the attached Substitute Form W-9, and sign, date and return the Substitute Form W-9 to the Exchange Agent.

A foreign person may qualify as an exempt recipient by submitting a properly completed IRS Form W-8, signed under penalties of perjury, attesting to that Holder’s exempt status. Please consult the enclosed “Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9” for additional guidance on which Holders are exempt from backup withholding.

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 Substitute Form W-9 (including how to obtain a TIN if you do not have one and how to complete the Substitute Form W-9 if the Interests are held in more than one name), consult the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute 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 2015 Notes, by execution of this Letter of Transmittal, shall waive any right to receive notice of the acceptance of 2015 Notes for exchange.

10

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 2015 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 2015 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. Security Transfer Taxes. Holders who tender their 2015 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 2015 Notes tendered, or if a transfer tax is imposed for any reason other than the exchange of 2015 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.

FILE SUBSTITUTE FORM W-9 WITH THE PAYOR BY FURNISHING YOUR TAXPAYER IDENTIFICATION NUMBER, WRITE “EXEMPT” ON THE FACE OF THE FORM (IN PART II OF THE FORM), SIGN AND DATE THE FORM AND RETURN TO THE PAYOR.

Certain payments other than interest, dividends, and patronage dividends that are not subject to information reporting are also not subject to backup withholding. For details, see sections 6041, 6041A, 6042, 6044, 6045, 6049, 6050A and 6050N of the Code, and the regulations under such sections.

Privacy Act Notice. — Section 6109 requires you to give your correct taxpayer identification number to Payors who must report the payments to the IRS. The IRS uses the numbers for identification purposes and to help verify the accuracy of your tax return. The IRS may also provide this information to the Department of Justice for civil and criminal litigation, and to cities, states, and the District of Columbia to carry out their tax laws. We may also disclose this information to other countries under a tax treaty, to federal and state agencies to enforce federal nontax criminal laws, or to federal law enforcement and intelligence agencies to combat terrorism. Payors must be given the numbers whether or not you are required to file tax returns. Payors must generally withhold 28% of taxable interest, dividends, and certain other payments to a payee who does not furnish a taxpayer identification number to a payor. Certain penalties may also apply.
