THIS AGREEMENT is made effective July 1, 2005, between CHESAPEAKE ENERGY CORPORATION, an Oklahoma corporation (the “Company”), and XXXXXX X. XxXXXXXXX, an individual (the “Executive”).

W I T N E S S E T H:

WHEREAS, the Company and the Executive entered into that certain Amended and Restated Employment Agreement dated effective July 1, 1998 as amended by the First Amendment to Amended and Restated Employment Agreement dated December 31, 1998, as further amended by the Second Amended and Restated Employment Agreement dated January 1, 2001, and as further amended by the Third Amended and Restated Employment Agreement dated January 1, 2004 (together the “Prior Agreements”);

WHEREAS, the Company has adopted the Founder Well Participation Program (the “FWP Program”) in order to provide for the participation by the Executive in the Company’s xxxxx; and

WHEREAS, the Company and the Executive desire to amend and restate the Prior Agreements in their entirety to reflect the foregoing and other changes to the arrangement between the Company and the Executive.

NOW, THEREFORE, in consideration of the mutual promises herein contained, the Company and the Executive agree as follows:

1.         Employment. The Company hereby employs the Executive and the Executive hereby accepts such employment subject to the terms and conditions contained in this Agreement. The Executive is engaged as an employee of the Company and the Executive and the Company do not intend to create a joint venture, partnership or other relationship that might impose a fiduciary obligation on the Executive or the Company in the performance of this Agreement.

2.         Executive’s Duties. The Executive is employed on a full-time basis. Throughout the term of this Agreement, the Executive will use the Executive’s best efforts and due diligence to assist the Company in the objective of achieving the most profitable operation of the Company and the Company’s affiliated entities consistent with developing and maintaining a quality business operation.

2.1 Specific Duties. During the term of this Agreement the Executive: (a) will serve as Chairman of the Board and Chief Executive Officer for the Company; (b) will be nominated for election or appointed to serve as a director of the Company; (c) will be appointed as an officer of one (1) or more of the Company’s subsidiaries; and (d) may be nominated for election or appointed to serve as a director of one (1) or more of the Company’s subsidiaries. The Executive agrees to use the Executive’s best efforts to perform all of the services required to fully and faithfully execute the offices and positions to which the Executive is appointed and such other services as may be reasonably directed by the Board of Directors of the Company in accordance with this Agreement.

2.2 Modifications. The precise duties to be performed by the Executive may be extended or curtailed in the discretion of the Board of Directors of the Company. However, except for termination for Cause (as hereinafter defined) under paragraph 6.1.2 of this Agreement, the failure of the Executive to be elected, be reelected or serve as a director of the Company during the term of this Agreement, the removal of the Executive as a member of the board of directors of the Company, the withdrawal of the designation of the Executive as Chairman of the Board and Chief Executive Officer of the Company, or the assignment of the performance of duties incumbent on the foregoing offices to other persons without the prior written consent of the Executive will constitute termination without Cause by the Company.

2.3 Rules and Regulations. From time to time, the Company may issue policies and procedures applicable to employees and the Executive including an Employment Policies Manual. The Executive agrees to comply with such policies and procedures, except to the extent such policies are inconsistent with this Agreement. Such policies and procedures may be supplemented, modified, changed or adopted without notice in the sole discretion of the Company at any time. In the event of a conflict between such policies and procedures and this Agreement, this Agreement will control unless compliance with this Agreement will violate any law or regulation applicable to the Company or its affiliated entities.

2.4 Stock Investment. During the term of this Agreement, the Executive agrees to hold shares of the Company’s common stock having an aggregate Investment Value (as hereafter defined) greater than five hundred percent (500%) of the compensation paid to the Executive under paragraphs 4.1 and 4.2 of this Agreement during such calendar year. Any shares of common stock acquired by the Executive prior to the date of this Agreement and still owned by the Executive during the term of this Agreement may be used to satisfy the requirement to own common stock. For purposes of this paragraph, the “Investment Value” of each share of stock will be as follows: (a) for shares purchased in the open market after the date of this Agreement the price

paid by the Executive for such shares; (b) for shares acquired after the date of this Agreement through the exercise of stock options, the grant of restricted stock, the conversion of preferred stock or other than through open market purchases, the fair market value of the common stock on the date the option was exercised, the stock was issued or the stock was acquired through the conversion of preferred stock, or the date such stock was otherwise acquired; and (c) for shares acquired prior to the date of this Agreement, the closing price for the Company’s stock on the New York Stock Exchange (the “NYSE”) on the date of this Agreement adjusted for subsequent stock splits. This paragraph will become null and void if the Company’s common stock ceases to be listed on the NYSE, the National Association of Securities Dealers Automated Quotation System or other national exchange. The Company has no obligation to sell or to purchase from the Executive any of the Company’s stock in connection with this paragraph 2.4 and has made no representations or warranties regarding the Company’s stock, operations or financial condition.

3.         Other Activities. Except for the activities (the “Permitted Activities”) permitted under paragraphs 3.1, 3.2 and 3.3 of this Agreement or approved by the Board of Directors, the Executive will not: (a) engage in activities which require such substantial services on the part of the Executive that the Executive is unable to perform the duties assigned to the Executive in accordance with this Agreement; (b) serve as an officer or director of any publicly held entity; or (c) directly or indirectly invest in, participate in or acquire an interest in any oil and gas business, including, without limitation, (i) producing oil and gas, (ii) drilling, owning or operating oil and gas leases or xxxxx, (iii) providing services or materials to the oil and gas industry, (iv) marketing or refining oil or gas, or (v) owning any interest in any corporation, partnership, company or entity which conducts any of the foregoing activities. The limitations in this paragraph 3 will not prohibit an investment by the Executive in publicly traded securities. The Executive is not restricted from maintaining or making investments, or engaging in other businesses, enterprises or civic, charitable or public service functions if such activities, investments, businesses or enterprises do not result in a violation of clauses (a) through (c) of this paragraph 3. Notwithstanding the foregoing, the Executive will be permitted to participate in the following activities that will be deemed to be approved by the Company, if such activities are undertaken in strict compliance with this Agreement.

3.1 Royalty Interests and Gifts. The foregoing restriction in clause (c) will not prohibit the ownership of royalty interests where the Executive owns or previously owned the surface of the land covered by the royalty interest and the ownership of the royalty interest is incidental to the ownership of the surface estate or the ownership of royalty, overriding royalty or working interests that are received by gift or inheritance.

3.2 Existing Interests. The Executive has in the past conducted oil and gas activities individually and through Chesapeake Investments, an Oklahoma Limited Partnership, and other entities owned or controlled by the Executive (collectively, the “Executive Affiliates”). The Executive will be

permitted to continue to conduct oil and gas activities (including participation in new xxxxx) directly or through the Executive Affiliates, but only to the extent such activities are conducted on oil and gas leases or interests which the Executive or Executive Affiliates owned or had the right to acquire as of the date of this Agreement or which the Executive or the Executive Affiliates acquired from the Company under the Prior agreements (collectively, the “Prior Interests”). To the extent that the oil and gas interests or activities covered by this paragraph 3.2 are operated by the Company the Executive agrees to pay any costs or expenses with respect to the Prior Interests in accordance with the FWP Program.

3.3 Company’s Activities. The Executive or the designated Executive Affiliate will be permitted to participate in the FWP Program. The Executive hereby agrees that the right to participate in the Company’s xxxxx after the date of this Agreement will be under the FWP Program and the Executive waives any right to participate under the Prior Agreements subsequent to the date of this Agreement. The parties hereto agree the FWP Program cannot be amended or modified without the prior written consent of the Board of Directors and the Executive.

4.         Executive’s Compensation. The Company agrees to compensate the Executive as follows:

4.1 Base Salary. A base salary (the “Base Salary”), in an annual rate of not less than Nine Hundred Fifty Thousand Dollars ($950,000.00), will be paid to the Executive in equal semi-monthly installments, beginning July 15, 2005, during the term of this Agreement.

4.2 Bonus. In addition to the Base Salary described at paragraph 4.1 of this Agreement, the Company may periodically pay bonus compensation to the Executive. Any bonus compensation will be at the absolute discretion of the Company in such amounts and at such times as the Compensation Committee of the Board of Directors of the Company may determine.

4.3 Equity Compensation. In addition to the compensation set forth in paragraphs 4.1 and 4.2 of this Agreement, the Executive may periodically receive grants of stock options, restricted stock or other equity related awards from the Company’s various stock compensation plans, subject to the terms and conditions thereof.

4.4 Benefits. The Company agrees to extend to the Executive retirement benefits, deferred compensation, reimbursement of reasonable expenditures for dues, travel and entertainment and any other benefits the Company provides to other executives or officers from time to time on the same terms as such benefits are provided to such individuals. The Company will also provide the Executive the opportunity to apply for coverage under the Company’s medical, life and disability plans, if any. If

the Executive is accepted for coverage under such plans, the Company will provide such coverage on the same terms as is customarily provided by the Company to the plan participants as modified from time to time. The following specific benefits will also be provided to the Executive at the expense of the Company.

4.4.1 Vacation. The Executive will be entitled to take up to five (5) weeks of paid vacation each calendar year during the term of this Agreement. No additional compensation will be paid for failure to take vacation and no vacation may be carried forward from one calendar year to another.

4.4.2 Membership Dues. The Company will reimburse the Executive for: (a) the monthly dues necessary to maintain a full membership in any club in the Oklahoma City area at which the Executive hosts business functions; and (b) the reasonable cost of any qualified business entertainment at such clubs. All other costs, including, without implied limitation, any initiation costs, initial membership costs, personal use and business entertainment unrelated to the Company will be the sole obligation of the Executive and the Company will have no liability with respect to such amounts.

4.4.3 Travel. For safety, security and efficiency the Executive will be required to utilize aircraft owned or leased by the Company for business and personal use in the Western Hemisphere (including North America, South America and the surrounding oceans) and will not be required to reimburse the Company for any cost related to such use. In addition, the Executive’s immediate family members may use such company aircraft for their personal use to the same extent. When a family member travels without the Executive, then the Executive agrees to reimburse the company for the variable costs of such use. For purposes of this Agreement, the variable cost of using the Company’s aircraft means the variable costs directly identifiable with each use (including fuel, pilot charges, landing fees, hourly charges under co-ownership arrangements and other such costs), but specifically excluding any fixed costs of the aircraft (including acquisition costs and depreciation). The Executive will: (a) not owe any additional amounts to the Company under this paragraph for guests or family members traveling with the Executive; and (b) pay all personal income taxes accruing as a result of the personal use of the Company’s aircraft by the Executive under this paragraph.

4.4.4 Accounting Support. The Executive will be permitted to utilize the Company’s office space, computer facilities and personnel to provide accounting services, records maintenance, tax advice and tax return preparation for the Executive’s (and his family’s) personal

business investments and activities. The Executive agrees to reimburse the Company an amount equal to one half of 50% of the salaries and bonuses paid by the Company to employees primarily engaged in providing such support services to the Executive or Xxx X. Xxxx. Such amounts will be billed monthly on an estimated basis, adjusted to actual at least once annually and paid by the Executive on receipt of an invoice from the Company. The cost of secretarial or general administrative support for the Executive will not be required to be reimbursed in whole or part by the Executive.

4.5 Gross-Up Payment. In the event it is determined that any payment or distribution by the Company or the Company Entities to or for the benefit of the Executive (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, but determined without regard to any additional payments required under this paragraph 4.5) (a “Payment”) is subject to the excise tax imposed by Section 4999 of the Internal Revenue Code (the “Code”) or any interest or penalties related to such excise tax (collectively, the “Excise Tax”), the Executive will be entitled to receive an additional payment (a “Gross-Up Payment”) from the Company. The Gross-Up Payment will be equal to the amount such that after payment by the Executive of all taxes (including the Excise Tax, income taxes, interest and penalties imposed with respect to such taxes) on the Gross-Up Payment, the Executive will retain an amount of the Gross-Up Payment equal to the Excise Tax imposed on the Payment.

4.5.1 Determination. Subject to the provisions of paragraph 4.5.2 all determinations required to be made under this paragraph 4.5 (including whether and when a Gross-Up Payment is required, the amount of such Gross-Up Payment and the assumptions to be utilized) will be made by a nationally recognized certified public accounting firm designated by the Executive (the “Accounting Firm”). The Accounting Firm will provide detailed supporting calculations both to the Company and the Executive within fifteen (15) business days of the receipt of notice from the Executive that there has been a Payment, or such earlier time as is reasonably requested by the Company. In the event that the Accounting Firm is serving as accountant or auditor for the individual, entity or group effecting a Change of Control (as hereinafter defined), the Executive will be entitled to appoint another nationally recognized accounting firm to make the determinations required under this paragraph (which accounting firm will then be referred to as the Accounting Firm hereunder). All fees and expenses of the Accounting Firm will be paid by the Company. Any Gross-Up Payment required to be paid under this paragraph 4.5 will be paid by the Company to the Executive within five (5) days of the receipt of the Accounting Firm’s determination. Any determination by the Accounting Firm will be binding on the Company and the Executive.

As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination by the Accounting Firm, the Gross-Up Payment made by the Company may be less than actually required (an “Underpayment”) consistent with the calculations required to be made hereunder. In the event that the Company exhausts its remedies pursuant to paragraph 4.5.2 below and the Executive thereafter is required to make a payment of any Excise Tax, the Accounting Firm will determine the amount of the Underpayment that has occurred and any such Underpayment will be promptly paid by the Company to or for the benefit of the Executive.

4.5.2 Contest of Claims. The Executive will notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by the Company of a Gross-Up Payment. Such notification will be given as soon as practicable but no later than ten (10) business days after the Executive is informed in writing of such claim and will apprise the Company of the nature of such claim and the date on which such claim is requested to be paid. The Executive will not pay such claim prior to the expiration of the thirty (30) day period following the date on which the Executive notifies the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies the Executive in writing prior to the expiration of such thirty (30) day period that the Company desires to contest such claim, the Executive will: (a) provide to the Company any information reasonably requested by the Company relating to such claim; (b) take such action in connection with contesting such claim as the Company reasonably requests in writing including, without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company; (c) cooperate with the Company in good faith as necessary to effectively contest such claim; and (d) permit the Company to participate in any proceedings relating to such claim. The Company will bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with the contest of the claim and agrees to indemnify and hold the Executive harmless, on an after-tax basis, for any Excise Tax or income tax (including interest and penalties with respect thereto) imposed as a result of such protest (including payment of costs and expenses as provided hereunder). Without limitation on the foregoing provisions, the Company will control all proceedings related to such contested claim, may at its sole option pursue or forgo any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may at its sole option either direct the Executive to pay the tax claimed and xxx for a refund or contest the claim in any permissible manner. The

Executive agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company reasonably determines. If the Company directs the Executive to pay a claim and xxx for a refund, the Company will be required to advance the amount of such payment to the Executive on an interest-free basis and agrees to indemnify and hold the Executive harmless, on an after-tax basis, from any Excise Tax or income tax (including interest or penalties with respect thereto) imposed with respect to such advance or with respect to any imputed income with respect to such advance, provided that any extension of the statute of limitations relating to payment of taxes for the taxable year of the Executive with respect to which such contested amount is claimed to be due is limited solely to such contested amount. Furthermore, the Company’s control of the contested claim will be limited to issues with respect to which a Gross-Up Payment would be payable hereunder and the Executive will be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority.

4.5.3 Refunds. If, after the receipt by the Executive of an amount advanced by the Company pursuant to paragraph 4.5.2, the Executive becomes entitled to receive any refund with respect to such claim the Executive will (subject to the Company’s complying with the requirements of paragraph 4.5.2) promptly pay to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto). If, after the receipt by the Executive of an amount advanced by the Company pursuant to paragraph 4.5.2, a determination is made that the Executive will not be entitled to any refund with respect to such claim and the Company does not notify the Executive in writing of its intent to contest such denial of refund prior to the expiration of (30) days after such determination, then the advance will be forgiven and will not be required to be repaid and the amount of such advance will offset, to the extent thereof, the amount of Gross-Up Payment required to be paid.

4.6 Compensation Review. The compensation of the Executive will be reviewed not less frequently than semi-annually by the Compensation Committee of the Board of Directors of the Company. The compensation of the Executive prescribed in paragraph 4 of this Agreement (including benefits) may be increased at the discretion of the Compensation Committee of the Board of Directors of the Company, but may not be reduced without the prior written consent of the Executive except as expressly provided herein. Notwithstanding the foregoing, the Board of Directors may reduce the amounts or awards under paragraph 4.2 or 4.3 of this Agreement on a reasonable basis

provided such decrease is applicable to all executives of the Company and does not result in a proportionately greater reduction in the amounts or awards to Executive under such paragraphs as compared to any other executive of the Company or any of the Company’s subsidiaries.

5.         Term. In the absence of termination as set forth in paragraph 6 below, this Agreement will extend for a term of five (5) years commencing on July 1, 2005, and ending on June 30, 2010 (the “Expiration Date”) as extended from time to time. Unless the Company provides thirty (30) days prior written notice of non-extension to the Executive, on each January 31 during the term of this Agreement, the term and the Expiration Date will be automatically extended for one (1) additional year so that the remaining term on this Agreement will be not less than four (4) and not more than five (5) years.

6.         Termination. This Agreement will continue in effect until the expiration of the term set forth in paragraph 5 of this Agreement unless earlier terminated pursuant to this paragraph 6.

6.1 Termination by Company. The Company will have the following rights to terminate this Agreement:

6.1.1 Termination without Cause. The Company may terminate this Agreement without Cause at any time by the service of written notice of termination to the Executive specifying an effective date of such termination not sooner than ninety (90) business days after the date of such notice (the “Termination Date”). In the event the Executive is terminated without Cause (other than a CC Termination under paragraph 6.3 of this Agreement), the Executive will receive as termination compensation: (a) Base Compensation (as hereafter defined) during the remaining term of this Agreement, but in any event through the Expiration Date; (b) any benefits provided by operation of paragraph 4.4 of this Agreement during the remaining term of this Agreement, but in any event through the Expiration Date (including, without implied limitation, suitable office space, secretarial and accounting support at the levels provided by the Company to the Executive at the time of termination); and (c) any vacation pay accrued through the Termination Date. For purposes of this Agreement the term “Base Compensation” means the Executive’s current Base Salary under paragraph 4.1 on the Termination Date plus the bonus compensation received by the Executive during the twelve (12) month period preceding the Termination Date.

6.1.2 Termination for Cause. The Company may terminate this Agreement for Cause. For purposes of this Agreement, “Cause” means: (a) the willful and continued failure of the Executive to perform substantially the Executive’s duties with the Company or

one of the Company Entities (other than a failure resulting from incapacity due to physical or mental illness), after a written demand for substantial performance is delivered to the Executive by the Board of Directors which specifically identifies the manner in which the Board of Directors believes that the Executive has not substantially performed the Executive’s duties; or (b) the willful engaging by the Executive in illegal conduct, gross misconduct or a clearly established violation of the Company’s written policies and procedures, in each case which is materially and demonstrably injurious to the Company. For purposes of this provision, an act or failure to act, on the part of the Executive, will not be considered “willful” unless it is done, or omitted to be done, by the Executive in bad faith or without reasonable belief that the Executive’s action or omission was in the best interests of the Company. Any act, or failure to act, based on authority given pursuant to a resolution duly adopted by the Board of Directors or based on the advice of counsel for the Company will be conclusively presumed to be done, or omitted to be done, by the Executive in good faith and in the best interests of the Company. In the event this Agreement is terminated for Cause, the Company will not have any obligation to provide any further payments or benefits to the Executive after the effective date of such termination. This Agreement will not be deemed to have terminated for Cause unless a written determination specifying the reasons for such termination is made, approved by a majority of the independent and disinterested members of the Board of Directors of the Company and delivered to the Executive. Thereafter, the Executive will have the right for a period of thirty (30) days to request a Board of Directors meeting to be held at a mutually agreeable time and location to be attended by the members of the Board of Directors in person within the following thirty (30) days, at which meeting the Executive will have an opportunity to be heard. Failing such determination and opportunity for hearing, any termination of this Agreement will be deemed to have occurred without Cause.

6.2 Termination by Executive. The Executive may voluntarily terminate this Agreement with or without Cause by the service of written notice of such termination to the Company specifying an effective date of such termination ninety (90) days after the date of such notice, during which time the Executive may use remaining accrued vacation days, or at the Company’s option, be paid for such days. In the event this Agreement is terminated by the Executive, neither the Company nor the Executive will have any further obligations hereunder including, without limitation, any obligation of the Company to provide any further payments or benefits to the Executive after the effective date of such termination.

6.3 Termination After Change in Control. If during the term of this Agreement there is a “Change of Control” and within three (3) years thereafter there is a CC Termination (as hereafter defined), then the Executive will be entitled to a severance payment (in addition to any other rights and other amounts payable to the Executive under this Agreement or otherwise) in an amount equal to the sum of the following: (a) three (3) times the Executive’s Base Compensation; plus (b) three (3) times the value of any benefits provided by operation of paragraph 4.4 of this Agreement during the preceding twelve (12) months; plus (c) any applicable Gross-Up Payment. If the foregoing amount is not paid within ten (10) days after the CC Termination, the unpaid amount will bear interest at the per annum rate of 12%. In addition, for a period of twelve (12) months after a CC Termination, the Company will provide at no cost to the Executive suitable office space and secretarial and accounting support at the levels presently provided by the Company.

6.3.1 Change of Control. For the purpose of this Agreement, a “Change of Control” means the occurrence of any of the following:

(a) The acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) (a “Person”) of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or more of either (i) the then outstanding shares of common stock of the Company (the “Outstanding Company Common Stock”) or (ii) the combined voting power of the then outstanding voting securities of the Company entitled to vote generally in the election of directors (the “Outstanding Company Voting Securities”). For purposes of this paragraph (a) the following acquisitions by a Person will not constitute a Change of Control: (i) any acquisition directly from the Company; (ii) any acquisition by the Company; (iii) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or any corporation controlled by the Company; or (iv) any acquisition by any corporation pursuant to a transaction which complies with clauses (i), (ii) and (iii) of paragraph (c) of this paragraph 6.3.1.

(b) The individuals who, as of the date hereof, constitute the Board of Directors (the “Incumbent Board”) cease for any reason to constitute at least a majority of the Board of Directors. Any individual becoming a director subsequent to the date hereof whose election, or nomination for election by the Company’s shareholders, is approved by a vote of at least a majority of the directors then comprising the Incumbent Board will be considered a member of the Incumbent Board as of the date hereof, but any such individual whose initial assumption of office occurs as a result of an actual or

threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf of a Person other than the Incumbent Board will not be deemed a member of the Incumbent Board as of the date hereof.

(c) The consummation of a reorganization, merger, consolidation or sale or other disposition of all or substantially all of the assets of the Company (a “Business Combination”), unless following such Business Combination: (i) all or substantially all of the individuals and entities who were the beneficial owners, respectively, of the Outstanding Company Common Stock and Outstanding Company Voting Securities immediately prior to such Business Combination beneficially own, directly or indirectly, more than 60% of, respectively, the then outstanding shares of common stock and the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors, as the case may be, of the corporation resulting from such Business Combination (including, without limitation, a corporation which as a result of such transaction owns the Company or all or substantially all of the Company’s assets either directly or through one or more subsidiaries) in substantially the same proportions as their ownership, immediately prior to such Business Combination of the Outstanding Company Common Stock and Outstanding Company Voting Securities, as the case may be, (ii) no Person (excluding any corporation resulting from such Business Combination or any employee benefit plan (or related trust) of the Company or such corporation resulting from such Business Combination) beneficially owns, directly or indirectly, 20% or more of, respectively, the then outstanding shares of common stock of the corporation resulting from such Business Combination or the combined voting power of the then outstanding voting securities of such corporation except to the extent that such ownership existed prior to the Business Combination and (iii) at least a majority of the members of the board of directors of the corporation resulting from such Business Combination were members of the Incumbent Board at the time of the execution of the initial agreement, or of the action of the Board, providing for such Business Combination.

(d) The approval by the shareholders of the Company of a complete liquidation or dissolution of the Company.

6.3.2 CC Termination. The term “CC Termination” means any of the following: (a) this Agreement expires in accordance with its terms; (b) this Agreement is not extended under paragraph 5 of this Agreement and the Executive resigns within one (1) year after such non-extension; (c) the Executive is terminated by the Company

other than under paragraphs 6.1.2, 6.4 or 6.5 based on adequate grounds; (d) the Executive resigns as a result of a change in the Executive’s duties or title, a reduction in the Executive’s then current compensation, a required relocation more than 25 miles from the Executive’s then current place of employment or a default by the Company under this Agreement; (e) the failure by the Company after a Change of Control to obtain the assumption of this Agreement, without limitation or reduction, by any successor to the Company or any parent corporation of the Company; or (f) after a Change of Control has occurred, the Executive agrees to remain employed by the Company for a period of three (3) months to assist in the transition and thereafter resigns.

6.4 Incapacity of Executive. If the Executive suffers from a physical or mental condition, which in the reasonable judgment of the Company’s Board of Directors, prevents the Executive in whole or in part from performing the duties specified herein for a period of four (4) consecutive months, the Executive may be terminated. Although the termination will be deemed as a termination with Cause, any compensation payable under paragraph 4 of this Agreement will be continued through the remaining term of this Agreement, but in any event through the Expiration Date. Notwithstand­ing the foregoing, the Executive’s Base Salary specified in paragraph 4.1 of this Agreement will be reduced by any benefits payable under any disability plans provided by the Company under paragraph 4.4 of this Agreement.

6.5 Death of Executive. If the Executive dies during the term of this Agreement, the Company may thereafter terminate this Agreement without compensation to the Executive’s estate except: (a) the obligation to continue the Base Salary payments under paragraph 4.1 of this Agreement for twelve (12) months after the effective date of such termination, and (b) the benefits described in paragraph 4.4 of this Agreement accrued through the effective date of such termination.

6.6 Effect of Termination. The termination of this Agreement will terminate all obligations of the Executive to render services on behalf of the Company, provided that the Executive will maintain the confidentiality of all information acquired by the Executive during the term of his employment in accordance with paragraph 7 of this Agreement. Except as otherwise provided in this paragraph 6, no accrued bonus, severance pay or other form of compensation will be payable by the Company to the Executive by reason of the termination of this Agreement. In the event that payments are required to be made by the Company under this paragraph 6, the Executive will not be required to seek other employment as a means of mitigating the Company’s obligations hereunder resulting from termination of the Executive’s employment and the Company’s obligations hereunder (including payment

of severance benefits) will not be terminated, reduced or modified as a result of the Executive’s earnings from other employment or self-employment. All keys, entry cards, credit cards, files, records, financial information, furniture, furnishings, equipment, supplies and other items relating to the Company will remain the property of the Company. The Executive will have the right to retain and remove all personal property and effects that are owned by the Executive and located in the offices of the Company. All such personal items will be removed from such offices no later than ten (10) days after the effective date of termination, and the Company is hereby authorized to discard any items remaining and to reassign the Executive’s office space after such date. Prior to the effective date of termination, the Executive will cooperate with the Company to provide for the orderly termination of the Executive’s employment.

6.7 Equity Compensation Provisions. Notwithstanding any provision to the contrary in any option agreement, restricted stock agreement, plan or other agreement relating to equity based compensation, in the event of a termination under paragraph 6.1.1 or 6.3 of this Agreement: (a) all units, stock options, incentive stock options, performance shares, stock appreciation rights and restricted stock held by Executive immediately prior to such termination will immediately become 100% vested; and (b) the Executive’s right to exercise any previously unexercised options will not terminate until the latest date on which such option would expire but for Executive’s termination of employment. To the extent Company is unable to provide for one or both of the foregoing rights the Company will provide in lieu thereof a lump-sum cash payment equal to the difference between the total value of such units, stock options, incentive stock options, performance shares, stock appreciation rights and shares of restricted stock (the “Equity Compensation Rights”) with the foregoing rights as of the date of Executive’s termination of employment and the total value of the Equity Compensation without the foregoing rights as of the date of the Executive’s termination of employment. The foregoing amounts will be determined by the Board of Directors in good faith based on a valuation performed by an independent consultant selected by the Board of Board of Directors.

7.         Confidentiality.
