Each of the Company and the Selling Stockholder will deliver its Firm Securities to or as instructed by Credit Suisse for the accounts of the several Underwriters in a form reasonably acceptable to Credit Suisse against payment of the purchase price for such Firm Securities by the Underwriters in Federal (same day) funds by a wire transfer to (i) an account at a bank specified by the Company (and acceptable to Credit Suisse) to Credit Suisse drawn to the order of the Company in the case of the 2,400,000 Firm Securities being purchased by the Underwriters from the Company and (ii) an account at a bank specified by the Selling Stockholder (and acceptable to Credit Suisse) to Credit Suisse drawn to the order of the Selling Stockholder in the case of the 2,400,000 Firm Securities being purchased by the Underwriters from the Selling Stockholder, at the office of Akin Gump ▇▇▇▇▇▇▇ ▇▇▇▇▇ & ▇▇▇▇ LLP, ▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇, at 9:00 A.M., New York time, on March 30, 2011, or at such other time not later than seven full business days thereafter as shall be agreed upon by the Company, the Selling Stockholder and Credit Suisse, such time being herein referred to as the “First Closing Date.” For purposes of Rule 15c6-1 under the Exchange Act, the First Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds and delivery of securities for all the Offered Securities sold pursuant to the offering. Delivery of the Firm Securities will be made through the facilities of the DTC unless Credit Suisse shall otherwise instruct.

In addition, upon written notice from Credit Suisse to the Company from time to time not more than 30 days subsequent to the date of the Final Prospectus, the Underwriters may purchase (i) all or less than all of the Optional Securities to be sold by the Company and (ii) all or less than all of the Optional Securities to be sold by the Selling Stockholder, in each case at the purchase price per Security to be paid for the Firm Securities.

In the event and to the extent the Underwriters exercise their right to purchase Optional Securities, the Underwriters shall purchase such Optional Securities from the Company and the Selling Stockholder on a pro rata basis, based on the maximum number of Optional Securities to be sold by each of the Company and the Selling Stockholder. The Company agrees to sell to the Underwriters the number of shares of Optional Securities specified in such notice in the amount not to exceed 360,000 shares of the Securities and the Underwriters agree, severally and not jointly, to purchase such Optional Securities. The Selling Stockholder agrees to sell to the Underwriters the number of shares of Optional Securities specified in such notice in the amount not to exceed 360,000 shares of the Securities.

No Optional Securities shall be sold or delivered unless the Firm Securities previously have been, or simultaneously are, sold and delivered. The right to purchase the Optional Securities or any portion thereof may be exercised from time to time and to the extent not previously exercised may be surrendered and terminated at any time upon notice by Credit Suisse to the Company.

Each Optional Closing Date shall be determined by Credit Suisse but shall be not later than five full business days after written notice of election to purchase Optional Securities is given. Each of the Company and the Selling Stockholder will deliver its Optional Securities being purchased by the Underwriters to or as instructed by Credit Suisse for the accounts of the several Underwriters in a form reasonably acceptable to Credit Suisse against payment of the purchase price for such Optional Securities by the Underwriters in Federal (same day) funds by wire transfer to (i) an account at a bank specified by the Company (and acceptable to Credit Suisse) to Credit Suisse drawn to the order of the Company in the case of Optional Securities purchased by the Underwriters from the Company and (ii) an account at a bank specified by the Selling Stockholder (and acceptable to Credit Suisse) to Credit Suisse drawn to the order of the Selling Stockholder in the case of the Optional Securities purchased by the Underwriters from the Selling Stockholder, at the office of Akin Gump ▇▇▇▇▇▇▇ ▇▇▇▇▇ & ▇▇▇▇ LLP, ▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇.

15 of the Act or Section 20 of the Exchange Act (each, an “Indemnified Party”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (c) below.

(b) Indemnification of Underwriters by Selling Stockholder. The Selling Stockholder will indemnify and hold harmless each Indemnified Party, against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of any Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to the above as such expenses are incurred; provided, however, that the Selling Stockholder shall be subject to such liability only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission is based upon the Selling Stockholder Information and provided, further, that the liability under this subsection of the Selling Stockholder shall be limited to an amount equal to the aggregate gross proceeds after underwriting commissions and discounts, but before expenses, to the Selling Stockholder from the sale of Securities sold by the Selling Stockholder hereunder.

(c) Indemnification of Company, its Directors and Officers and the Selling Stockholder. Each Underwriter will severally and not jointly indemnify and hold harmless the Company, each of its directors and each of its officers who signs a Registration Statement and

each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and the Selling Stockholder (each, an “Underwriter Indemnified Party”), against any losses, claims, damages or liabilities to which such Underwriter Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or the alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Final Prospectus furnished on behalf of each Underwriter: the concession and reallowance figures appearing in the fourth paragraph and information with respect to stabilization transactions appearing in the twelfth paragraph, in each case under the caption “Underwriting”.

(d) Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a), (b) or (c) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a), (b) or (c) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a), (b) or (c) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from

all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(e) Contribution. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a), (b) or (c) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the other from the offering of the Offered Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Selling Stockholder on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Selling Stockholder bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Selling Stockholder or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (e). Notwithstanding the provisions of this subsection (e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged untrue statement or omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint. The Company, the Selling Stockholder and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 8(e). The Selling Stockholder’s obligation under this subsection (e) to contribute shall be limited to an amount equal to the aggregate gross proceeds after underwriting commissions and discounts, but before expenses, to the Selling Stockholder from the sale of Securities sold by the Selling Stockholder hereunder.

(f) The obligations of the Company and the Selling Stockholder under this Section 8 shall be several and not joint.

9. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder on either the First Closing Date or any Optional Closing Date and the aggregate number of shares of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date, Credit Suisse may make arrangements satisfactory to the Company and the Selling Stockholder for the purchase of such Offered Securities by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate number of shares of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date and arrangements satisfactory to Credit Suisse, the Company and the Selling Stockholder for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholder, except as provided in Section 10 (provided that if such default occurs with respect to Optional Securities after the First Closing Date, this Agreement will not terminate as to the Firm Securities or any Optional Securities purchased prior to such termination). As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

10. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Selling Stockholder, of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Selling Stockholder, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 9 hereof, the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities, and the respective obligations of the Company, the Selling Stockholder and the Underwriters pursuant to Section 8 hereof shall remain in effect. In addition, if any Offered Securities have been purchased hereunder, the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect.

OFFICER’S CERTIFICATE

(Reserve Reports)

Capitalized terms used but not defined in this certificate have the meaning ascribed to them in the Underwriting Agreement, dated March 24, 2011, among the Gulfport Energy Corporation, CD Holding Company, LLC, as selling stockholder, and Credit Suisse Securities (USA) LLC and ▇▇▇▇▇▇▇ ▇▇▇▇ & Company L.L.C., as representatives of the several Underwriters named in Schedule 1 thereto (the “Underwriting Agreement”). This certificate is being delivered pursuant to the terms of the Underwriting Agreement.

In connection with the public offering of shares of common stock of the Company, and to assist the Underwriters (as defined in the Underwriting Agreement) in conducting and documenting their investigation of the affairs of the Company in connection with the offering of the Securities, I, ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, Senior Reservoir Engineer of Gulfport Energy Corporation, a Delaware corporation, (the “Company”), do hereby certify as follows:

1. As Senior Reservoir Engineer of the Company, for each of the years ended December 31, 2008, 2009 and 2010, I have had primary supervisory responsibility for the preparation of internal reports (collectively the “Reports”) of the estimates of proved reserves and related future revenue, net to the Company’s interest, for each of (i) the properties in the East and West Hackberry Fields, (ii) the Company’s interest in the ▇▇▇▇▇▇ Play and (iii) certain other minor interests in various states.

2. I am familiar with the standards pertaining to the estimating and auditing of oil and gas reserve information promulgated by the Securities and Exchange Commission (the “SEC”), as in effect at each of the year ends of the respective reports.

3. The estimates of the Company’s proved reserves contained in each of the Reports, and the computations made in connection therewith, were made in accordance with the provisions of Rule 4-10 of Regulation S-X promulgated by the SEC and have been prepared in a manner consistent and in compliance with such other published interpretations and criteria pertaining to the estimation of proved oil and gas reserves and related future net revenues promulgated by the SEC, as such Rule was in effect and as such interpretations and criteria were published as of the year end date to which the Report relates.

4. The engineering estimates were based on the latest production data available at the time of the estimates, usually through November or December of the year end to which the Report relates. As of the date of this letter, no additional information has been brought to my attention which would lead me to believe that there would be a material downward change in the estimated proved reserves at December 31, 2010 attributable to the Company’s interests other than as a result of pricing changes and production since December 31, 2010.

5. I have reviewed the circled reserve information related to certain of the Company’s proved reserves derived from the Reports on pages attached hereto as Appendix A

Exhibit A – Page 1

from the spreadsheet provided by the Company. I confirm that such circled information has been accurately derived from the Reports.

IN WITNESS WHEREOF, I have signed this certificate.

Exhibit A – Page 2

EXHIBIT B

Each of the Company and Grizzly Holdings, Inc. (the “Subsidiary”) is a corporation that is validly existing and in good standing under the laws of the State of Delaware, the jurisdiction of its incorporation, and is duly qualified and is in good standing as a foreign corporation in each jurisdiction listed on Schedule A hereto.

The Company has the corporate power and authority to own, lease, hold and operate its properties and to conduct the business in which it is engaged as described in the Registration Statement, the Final Prospectus and the General Disclosure Package, and to enter into and perform its obligations under the Underwriting Agreement. The Subsidiary has the corporate power and authority to own, lease, hold and operate its properties and to conduct the business in which it is engaged as described in the Registration Statement, the Final Prospectus and the General Disclosure Package.

3.	The Company (a) has the corporate power to execute, deliver and perform the Underwriting Agreement, (b) has taken all corporate action necessary to authorize the execution, delivery and performance of the Underwriting Agreement and (c) has duly executed and delivered the Underwriting Agreement.

The execution and delivery by the Company of the Underwriting Agreement do not, and the performance by it of its obligations thereunder will not, (i) whether with or without the giving of notice or passage of time or both, constitute a breach of, or default or Repayment Event under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to, any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument filed as an exhibit to the Registration Statement, the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2010 or any of the Company’s subsequent Current Reports on Form 8-K and, in each case, to which the Company is a party or by which it is bound, or to which any of the assets, properties or operations of the Company is subject (the “Reviewed Agreements”), (ii) result in a violation of the Certificate of Incorporation or Bylaws of the Company, (iii) result in the violation of any law, rule or regulation of any Included Law (as defined below), or (iv) result in any violation of any order, writ, judgment or decree of any governmental authority identified in Schedule B hereto.

No authorization, approval or other action by, and no notice to or registration or filing with, any United States federal or state governmental authority or regulatory body, or any third party that is a party to any Reviewed Agreements, is required for the due execution, delivery or performance by the Company of the Underwriting Agreement, except as have been obtained and are in full force and effect under the Securities Act of 1933, as amended (the “Securities Act”) and as may be required under the securities or blue sky laws of any jurisdiction in the United States in connection with the offer and sale of the Offered Securities.

6.	The Company is not, and as a result of the transactions contemplated by the Underwriting Agreement (including the receipt of proceeds from the offering contemplated therein) will

Exhibit B – Page 1

not be, required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”).

The Company Offered Securities have been duly authorized by the Company and, when issued and delivered as provided in the Underwriting Agreement, the Company Offered Securities will be validly issued, fully paid and non-assessable and the issuance of the Company Offered Securities will not be subject to preemptive rights pursuant to the DGCL, the Certificate of Incorporation or By-Laws of the Company or any Reviewed Agreement. The Selling Stockholder Offered Securities have been duly authorized by the Company and are validly issued, fully paid and non-assessable and the Selling Stockholder Offered Securities were not, when issued, subject to preemptive rights pursuant to the DGCL, the Certificate of Incorporation or By-Laws of the Company or any Reviewed Agreement.

8.	The authorized equity capitalization as set forth in the Certificate of Incorporation of the Company consists of 100,000,000 shares of common stock, par value $0.01 per share, and 5,000,000 shares of preferred stock, par value $0.01 per share.

9.	The Offered Securities conform in all material respects to the description thereof set forth in the Registration Statement, the General Disclosure Package and the Final Prospectus.

10.

The Registration Statement was declared effective under the Securities Act on July 28, 2010 and the Final Prospectus was filed with the Commission on March , 2011 in accordance with Rule 424(b). To our knowledge, no stop order suspending the effectiveness of the Registration Statement or any part thereof has been issued and no proceedings for that purpose have been instituted or are pending before or contemplated by the Commission.

11.

The statements in the Prospectus and the General Disclosure Package under the caption “Description of Capital Stock,” in so far as such statements constitute a summary of the documents referred to therein, matters of law or legal proceedings, fairly present in all material respects the information required to be shown and are fair and accurate summaries.

12.

The statements made in the General Disclosure Package and Final Prospectus under the caption “Certain U.S. Federal Income Tax Considerations for Non-United States Holders,” insofar as they purport to be summaries of the terms of statutes, rules or regulations, constitute accurate summaries of the terms of such statutes, rules or regulations in all material respects.

13.	The form of stock certificate used to evidence the certificated Offered Securities is in a form that complies in all material respects with all applicable statutory requirements under the DGCL.

14.	To such counsel’s knowledge, no holder of any security of the Company has any right to require registration of shares of common stock or any other security of the Company in the Registration Statement that has not been waived.

15.	Assuming that (i) the Selling Stockholder has delivered to the Company’s transfer agent (the “Transfer Agent”) a stock power endorsed in blank with respect to the Selling Stockholder Offered Securities, (ii) the Selling Stockholder has authorized the Transfer Agent to use the

Exhibit B – Page 2

stock power to transfer such Selling Stockholder Offered Securities to the Underwriters or as directed by the Underwriters and such Selling Stockholder Offered Securities have been so transferred and issued, (iii) the Transfer Agent has acknowledged that it holds such Selling Stockholder Offered Securities that were formerly owned by the Selling Stockholder for the account of the Underwriters, (iv) the Underwriters have purchased such Selling Stockholder Offered Securities pursuant to the Underwriting Agreement by making payment therefor as provided therein, and (v) neither the Underwriters nor the Transfer Agent have granted a security interest in such Selling Stockholder Offered Securities, the Underwriters will have acquired a security entitlement with respect to such Selling Stockholder Offered Securities purchased by the Underwriters, and an action based on an adverse claim to such Selling Stockholder Offered Securities may not be asserted against the Underwriters with respect to such Selling Stockholder Offered Securities if the Underwriters do not have notice of the adverse claim. As used in this opinion, terms defined in Article 8 of the Uniform Commercial Code of the State of New York (the “NY UCC”) shall have the meanings set forth therein, including, without limitation, the terms “adverse claim,” “notice of an adverse claim,” [“securities account,”] [“securities intermediary”] and “security entitlement,” which are defined in Sections 8-102(a)(1), 8-105, 8-501(a), 8-102(a)(14) and 8-102(a)(17) of the NY UCC, respectively.

Negative Assurance

Because the primary purpose of such counsel’s professional engagement was not to establish or confirm factual matters or financial, accounting, statistical or reserve information, and because many determinations involved in the preparation of the Registration Statement, the General Disclosure Package or the Final Prospectus are of a wholly or partially non-legal character, except as set forth in paragraphs 9, 11 and 12 of this letter, such counsel is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained or incorporated by reference in the Registration Statement, the General Disclosure Package and the Final Prospectus and such counsel makes no representation that it has independently verified the accuracy, completeness or fairness of such statements.

However, in the course of our acting as counsel to the Company in connection with its preparation of the Registration Statement, the General Disclosure Package and the Final Prospectus, prior to the filing of the Registration Statement, the Preliminary Prospectus and the Final Prospectus, such counsel participated in conferences and telephone conversations with representatives of the Company, the internal reserve engineer of the Company, representatives of the independent public accountants for the Company, representatives of the independent petroleum engineers of the Company, representatives of the Selling Stockholder, representatives of the Underwriters and representatives of the Underwriters’ counsel, during which conferences and conversations the contents of the Registration Statement, the General Disclosure Package and the Final Prospectus and related matters were discussed, and such counsel reviewed certain corporate records and documents furnished to such counsel by the Company and certain documents publicly filed by the Company with the Commission.

Subject to the foregoing, such counsel confirms to you that, on the basis of the information we gained in the course of performing the services referred to above:

Each of the Registration Statement, the General Disclosure Package and the Final Prospectus, and each amendment or supplement thereto, including the documents incorporated by reference therein, in each case as of their respective effective or issue dates appeared on its face, as supplemented or amended, to be appropriately responsive in all material respects to the requirements of the Securities Act and the applicable rules and regulations thereunder, except that (i) we express no view as to the financial statements and related notes and schedules or other financial data, accounting data or reports on the effectiveness of internal control over financial reporting; oil and gas reserves; or statistical data derived from such financial data or oil and gas reserves and related future net cash flows contained in or omitted from the Registration Statement, the Final Prospectus or the General Disclosure Package and (ii) we express no view of the anti-fraud provisions of the U.S. securities Laws and the rules and regulations promulgated under such provisions; and

Re:

Gulfport Energy Corporation (“Gulfport”)

Ladies and Gentlemen:

I have acted as counsel to CD Holding Company, LLC, a Delaware limited liability company (the “Selling Stockholder”), in connection with the sale of the Selling Stockholder Offered Securities. All capitalized terms not otherwise defined herein shall have the meanings assigned them in the Underwriting Agreement among Gulfport, the Selling Stockholder and you, as representatives of the several underwriters, dated March , 2011 (the “Underwriting Agreement”). This opinion letter is being furnished to you pursuant to Section 7(g) of the Underwriting Agreement. As counsel for the Selling Stockholder, I examined the originals or certified copies, or copies which were otherwise authenticated to my satisfaction, of the limited liability company records of the Selling Stockholder, and such other documents or certificates of public officials which I deemed necessary for the opinions expressed herein.

In rendering this opinion, I have examined originals or copies, certified or otherwise identified to my satisfaction, of the Underwriting Agreement and have investigated such questions of law, and have examined such other corporate records of the Selling Stockholder and other documents, and have obtained and relied (without independent investigation) upon such certificates and assurances from public officials, as I have deemed necessary as a basis for the purpose of rendering this opinion.

For the purpose of rendering this opinion, I have assumed, without any independent investigation, the capacity of all natural persons, the authenticity of all documents and instruments submitted to me as originals, and the conformity to authentic original documents and instruments of all documents and instruments submitted to me as certified, conformed photostatic or facsimile copies.

This opinion is rendered as of the date hereof, and I disclaim any undertaking to advise of any changes that may hereafter be brought to my attention. I express no opinion other than as expressly set forth herein. No expansion of the opinions expressed herein may or should be made by implication or otherwise.

Based on the foregoing and upon such investigation as I have deemed necessary, and subject to the qualifications and exceptions herein contained, I am of the opinion that:

1. The Selling Stockholder is validly existing as a limited liability company under the laws of the State of Delaware.

Exhibit C – Page 1

2. The Selling Stockholder has the power and authority to enter into and perform its obligations under the Underwriting Agreement. The execution and delivery of the Underwriting Agreement by the Selling Stockholder, and the performance by the Selling Stockholder of its obligations thereunder, have been duly authorized by all necessary limited liability company action on the part of the Selling Stockholder. The Underwriting Agreement has been duly executed and delivered by the Selling Stockholder.

3. Neither the sale of the Selling Stockholder Offered Securities nor the performance by the Selling Stockholder of its obligations under the Underwriting Agreement will, to my knowledge, (i) with or without the giving of notice or passage of time or both, conflict with or constitute a default under, any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or any other agreement or instrument known to me to which the Selling Stockholder is a party or by which it is bound, (ii) result in a violation of the organizational documents of the Selling Stockholder, (iii) result in the violation of any law, rule or regulation of any Relevant Law or (iv) result in any violation of any order, writ, judgment or decree of any governmental authority known to me and identified in a schedule to my opinion.

4. No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any Federal or state governmental authority or agency is required for the due execution and delivery of the Underwriting Agreement by the Selling Stockholder and the performance by the Selling Stockholder of its obligations under the Underwriting Agreement except for (i) those that have been obtained or made and (ii) those that may be required under state securities laws or blue sky laws.

The opinions expressed herein are qualified in their entirety as follows: (a) no opinion is expressed with respect to laws other than the Federal laws of the United States, the State of New York, the Delaware General Corporation Law and the Limited Liability Company Act of the State of Delaware (the “Relevant Laws”); and (b) to the extent that any one or more of the foregoing opinions relates to the enforceability of any agreement or instrument: (1) the opinions are subject to the effect of applicable laws or judicial decisions regarding bankruptcy, reorganization, insolvency, fraudulent transfers, moratorium and other laws affecting creditors’ rights and debtors’ relief generally; (2) the enforceability of the provisions of any such agreement or instrument is subject to the application of principles of equity, whether in a proceeding at law or in equity, including the exercise of discretionary powers of any tribunal before which equitable remedies may be sought (including, without limitation, specific performance and injunctive relief); and (3) the enforceability of the provisions of any such agreement or instrument in accordance with its respective terms may be limited by laws affecting the remedies which it provides, including, but not limited to, laws and judicial decisions limiting such enforceability.

The opinion expressed herein is based upon the Relevant Laws and interpretations thereof in effect on the date hereof, and the facts and circumstances in existence on the date hereof, and I assume no obligation to revise or supplement this opinion letter should any such law or interpretation be changed by legislative action, judicial decision or otherwise or should there be any change in such facts or circumstances after the date hereof.

Exhibit C – Page 2

The opinions expressed herein are matters of professional judgment, are not a guarantee of result, are effective only as of the date hereof, may not be relied upon for any other purpose and may not be furnished to or relied upon by any other person other than the addressees hereof and their successors and permitted assignees for any purpose without my prior written consent. This opinion is rendered as of the date hereof, and I disclaim any undertaking to advise of any changes that may hereafter be brought to my attention. I express no opinion other than as expressly set forth herein. No expansion of the opinions expressed herein may or should be made by implication or otherwise.

Very truly yours,
