<p><font size="2">&nbsp;</font></p>

<p><font size="2">Section 1031 of the Oklahoma General Corporation Act, under which the Company is incorporated, authorizes the indemnification of directors and officers under certain circumstances. Article VIII of the Certificate of Incorporation of the Company and Article VI of the Bylaws of the Company also provide for indemnification of directors and officers under certain circumstances. These provisions, together with the Company&#146;s indemnification obligations under individual indemnity agreements with its directors and officers, may be sufficiently broad to indemnify such persons for liabilities under the Securities Act of 1933 (the &#147;Securities Act&#148;), as amended. In addition, the Company maintains insurance, which insures its directors and officers against certain liabilities. </font></p>

<p><font size="2">&nbsp;</font></p>

<p><font size="2">The Oklahoma General Corporation Act provides for indemnification of each of the Company&#146;s officers and directors against (a) expenses, including attorneys&#146; fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by them in connection with any action, suit or proceeding brought by reason of such person being or having been a director, officer, employee or agent of the Company, or of any other corporation, partnership, joint venture, trust or other enterprise at the request of the Company, other than an action by or in the right of the Company. To be entitled to indemnification, the individual must have acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interest of the Company, and with respect to any criminal action, the person seeking indemnification had no reasonable cause to believe that the conduct was
unlawful and (b) expenses, including attorneys&#146; fees, actually and reasonably incurred in connection with the defense or settlement of any action or suit by or in the right of the Company brought by reason of the person seeking indemnification being or having been a director, officer, employee or agent of the Company, or any other corporation, partnership, joint venture, trust or other enterprise at the request of the Company, provided the actions were in good faith and were reasonably believed to be in or not opposed to the best interest of the Company, except that no indemnification shall be made in respect of any claim, issue or matter as to which the individual shall have been adjudged liable to the Company, unless and only to the extent that the court in which such action was decided has determined that the person is fairly and reasonably entitled to indemnity for such expenses which the court deems proper. Article VIII of the Company&#146;s Certificate of Incorporation
provides for indemnification of the Company&#146;s directors and officers. The Oklahoma General Corporation Act also permits the Company to purchase and maintain insurance on behalf of the Company&#146;s directors and officers against any liability arising out of their status as such, whether or not the Company would have the power to indemnify them against such liability. These provisions may be sufficiently broad to indemnify such persons for liabilities arising under the Securities Act. </font></p>

<p><font size="2">&nbsp;</font></p>

<p><font size="2">The Company has entered into indemnity agreements with each of its directors and executive officers. Under each indemnity agreement, the Company will pay on behalf of the indemnitee any amount which he is or becomes legally obligated to pay because of (a) any claim or claims from time to time threatened or made against him by any person because of any act or omission or neglect or breach of duty, including any actual or alleged error or misstatement or misleading statement, which he commits or suffers while acting in his capacity as a director and/or officer of the Company or an affiliate or (b) being a party, or being threatened to be made </font></p>

The payments which the Company would be obligated to make under an indemnification agreement could include damages, charges, judgments, fines, penalties, settlements and costs, cost of investigation and cost of defense of legal, equitable or criminal actions, claims or proceedings and appeals therefrom, and costs of attachment, supersedeas, bail, surety or other bonds. The Company also provides liability insurance for each of its directors and executive officers.</font></p>

Item 4. Description of Securities.
Not applicable.

Item 5. Interests of Named Experts and Counsel.
Not applicable.
Item 6. Indemnification of Directors and Officers.
Section 1031 of the Oklahoma General Corporation Act, under which the Company is incorporated, authorizes the indemnification of directors and officers under certain circumstances. Article VIII of the Certificate of Incorporation of the Company and Article VI of the Bylaws of the Company also provide for indemnification of directors and officers under certain circumstances. These provisions, together with the Company's indemnification obligations under individual indemnity agreements with its directors and officers, may be sufficiently broad to indemnify such persons for liabilities under the Securities Act of 1933 (the "Securities Act"), as amended. In addition, the Company maintains insurance, which insures its directors and officers against certain liabilities.
The Oklahoma General Corporation Act provides for indemnification of each of the Company's officers and directors against (a) expenses, including attorneys' fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by them in connection with any action, suit or proceeding brought by reason of such person being or having been a director, officer, employee or agent of the Company, or of any other corporation, partnership, joint venture, trust or other enterprise at the request of the Company, other than an action by or in the right of the Company. To be entitled to indemnification, the individual must have acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interest of the Company, and with respect to any criminal action, the person seeking indemnification had no reasonable cause to believe that the conduct was
unlawful and (b) expenses, including attorneys' fees, actually and reasonably incurred in connection with the defense or settlement of any action or suit by or in the right of the Company brought by reason of the person seeking indemnification being or having been a director, officer, employee or agent of the Company, or any other corporation, partnership, joint venture, trust or other enterprise at the request of the Company, provided the actions were in good faith and were reasonably believed to be in or not opposed to the best interest of the Company, except that no indemnification shall be made in respect of any claim, issue or matter as to which the individual shall have been adjudged liable to the Company, unless and only to the extent that the court in which such action was decided has determined that the person is fairly and reasonably entitled to indemnity for such expenses which the court deems proper. Article VIII of the Company's Certificate of Incorporation
provides for indemnification of the Company's directors and officers. The Oklahoma General Corporation Act also permits the Company to purchase and maintain insurance on behalf of the Company's directors and officers against any liability arising out of their status as such, whether or not the Company would have the power to indemnify them against such liability. These provisions may be sufficiently broad to indemnify such persons for liabilities arising under the Securities Act.
The Company has entered into indemnity agreements with each of its directors and executive officers. Under each indemnity agreement, the Company will pay on behalf of the indemnitee any amount which he is or becomes legally obligated to pay because of (a) any claim or claims from time to time threatened or made against him by any person because of any act or omission or neglect or breach of duty, including any actual or alleged error or misstatement or misleading statement, which he commits or suffers while acting in his capacity as a director and/or officer of the Company or an affiliate or (b) being a party, or being threatened to be made
4
a party, to any threatened, pending or contemplated action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he is or was an officer, director, employee or agent of the Company or an affiliate or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise. The payments which the Company would be obligated to make under an indemnification agreement could include damages, charges, judgments, fines, penalties, settlements and costs, cost of investigation and cost of defense of legal, equitable or criminal actions, claims or proceedings and appeals therefrom, and costs of attachment, supersedeas, bail, surety or other bonds. The Company also provides liability insurance for each of its directors and executive officers.

Item 9. Undertakings.
(a)
The Registrant hereby undertakes:
(1)
To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:
(i)
To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
(ii)
To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement;
(iii)
To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement;
provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this Registration Statement.
(2)
That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
6
(3)
To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(b)        The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c)        Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the
opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

SIGNATURES
Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Oklahoma City, State of Oklahoma on June 28, 2005.

Re:
Chesapeake Energy Corporation Long Term Incentive Plan
Ladies and Gentlemen:
We refer to the Registration Statement on Form S-8 being filed by Chesapeake Energy Corporation, an Oklahoma corporation (the "Company"), with the Securities and Exchange Commission under the Securities Act of 1933, relating to the registration of 3,000,000 shares of common stock, par value $.01 per share (the "Shares"), of the Company to be issued pursuant to the Chesapeake Energy Corporation Long Term Incentive Plan (the "Plan"). We have examined the Registration Statement, including its exhibits, and certain corporate records of the Company, and we have made such other investigation as we have deemed necessary in order to render the opinions expressed herein.
Based on the foregoing, we are of the opinion that the Shares, when issued for legally sufficient consideration under the Oklahoma General Corporation Act and in accordance with the terms of the Plan, will be legally issued, fully paid and nonassessable.
This opinion letter is limited to the Oklahoma General Corporation Act.
We hereby consent to the filing of this opinion as an exhibit to the Registration Statement. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act of 1933.
Very truly yours,
/s/WINSTEAD SECHREST & MINICK P.C.
