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

 

	 	4.1	 Base Salary. A base salary (the “Base Salary”), at the initial annual rate of not less than Three Hundred Fifty Thousand Dollars
($350,000.00) will be paid to the Executive in regular installments in accordance with the Company’s designated payroll schedule through December 31, 2012, increasing to not less than Five

	 	
Hundred Thousand Dollars ($500,000.00) during the Executive’s second year of employment defined as calendar year 2013, and not less than Six Hundred Fifty Thousand Dollars ($650,000.00)
during the Executive’s third year of employment defined as calendar year 2014,, assuming the Executive’s continued employment with the Company at the time of that increase. 

 

	 	4.2	Bonus. The Company will pay to the Executive a signing bonus in the amount of Two Hundred Fifty Thousand Dollars ($250,000.00), payable upon the Executive
signing a contract to acquire permanent housing in the Oklahoma City, OK area. If, during the first year of employment, the Executive is terminated for Cause or elects to voluntarily terminate employment with the Company for any reason, the
Executive agrees to repay a pro-rata share of the signing bonus. Such repayment shall be equal to the total amount of the signing bonus multiplied by the number of months not worked during the 12 month period, divided by 12 months. Additionally, the
Company will pay to the Executive guaranteed first year annual bonus compensation of not less than Three Hundred Fifty Thousand Dollars ($350,000.00) payable not later than January 15, 2013, guaranteed second year annual bonus compensation of
not less than Five Hundred Thousand Dollars ($500,000.00) payable not later than January 15, 2014 and guaranteed third year annual bonus compensation of not less than Six Hundred Fifty Thousand Dollars ($650,000.00) payable not later than
January 15, 2015. Bonus compensation shall be paid to the Executive by separate check or wire transfer apart from Executive’s Base Salary described above in Paragraph 4.1, net of standard, appropriate employment-related deductions
(including federal income tax at the applicable supplemental tax withholding rate), under the appropriate Internal Revenue Service (“IRS”) guidelines and applicable state tax rules. In order to be eligible for the bonus compensation set
forth herein and any future bonuses, the Executive must be an active full-time employee of the Company on the bonus payment date(s) selected by the Company. The Executive recognizes and acknowledges that except as provided above, the award of
bonuses is not guaranteed or promised in any way. Additionally, in the event the Executive resigns employment, the Executive shall not be eligible for any bonus compensation that may have otherwise been payable after such initial notice of
resignation. 

  

	 	4.3	 Equity Compensation. In addition to the compensation set forth in paragraphs 4.1 and 4.2 of this Agreement, on the last business day of the
month subsequent to the Executive’s initial month of employment, the Executive will be granted the standard new employee initial award of one hundred (100) shares of Chesapeake Energy Corporation (“CHK”) restricted stock. Upon
the Executive signing a contract to acquire permanent housing in the Oklahoma City, OK area, an additional restricted stock award (“Sign-On Stock”) with a value of Two Hundred Fifty Thousand Dollars ($250,000.00) will be issued to the
Executive. The Sign-On Stock award will be calculated using the closing market value on the last business day of the Executive’s initial month of employment and will be issued on the last business day of the month the Executive signs a contract
to acquire permanent housing in the Oklahoma City, OK area. Furthermore, the Executive will be granted a minimum value of Eight Hundred Thousand Dollars ($800,000.00) of CHK restricted stock not

	 	
later than January 15, 2013, a minimum value of One Million Dollars ($1,000,000.00) of CHK restricted stock not later than January 15, 2014 and a minimum of One Million Two Hundred
Thousand Dollars ($1,200,000.00) of CHK restricted stock not later than January 15, 2015. The corresponding number of shares to be awarded will be calculated using the closing stock price as of the grant date of the award. Vesting for all stock
awards will occur over a four year period (at 25% per year in arrears) under the terms of CHK’s equity compensation plans. Such equity compensation shall be awarded on the regularly scheduled dates selected by the Company for the granting
of such equity compensation to other executive employees. In order to be eligible for the equity compensation set forth herein, the Executive must be an active full-time employee of the Company on the equity grant dates. Further, the terms and
provisions of the Equity Compensation Plans control and direct the award of CHK restricted stock and any conflict between this Agreement and the Equity Compensation Plans will be resolved in favor of the terms and provisions of the Equity
Compensation Plans. 

  

	 	4.4	Benefits. The Company will provide the Executive such retirement benefits, reimbursement of reasonable expenditures for dues, travel and entertainment and such
other benefits as are customarily provided to similarly situated executives of the Company and as are set forth in and governed by the Company’s Employment Policies Manual. 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 make such coverage available to the Executive on the same terms as is customarily provided
by the Company to the plan participants as modified from time to time. The Executive is subject to all of the terms and provisions of the Company’s benefit plans or policies. The following specific benefits will also be provided to the
Executive at the expense of the Company: 

  

	 	4.4.1	Relocation Allowance. In addition to the compensation set forth in paragraphs 4.1 and 4.2 of this Agreement, the Company will provide a relocation allowance (the

voluntarily terminate employment with the Company following the Executive’s relocation and during the first twelve (12) months of employment, the Executive agrees to repay a pro-rata share of the Relocation Allowance. Such repayments shall
be equal to the total amount of the Relocation Allowance multiplied by the months not worked during the twelve (12) month period, divided by twelve (12) months. In addition to the Relocation Allowance, the Company will provide
reimbursement of reasonable temporary housing rental for up to ninety (90) days following the Executive’s relocation to the Oklahoma City, OK area. Such reimbursement of reasonable temporary housing rental is subject to applicable taxes
under the appropriate IRS guidelines and applicable state tax rules. 

	 	4.4.2	COBRA Reimbursement. In addition to the compensation set forth in paragraphs 4.1 and 4.2 of this Agreement, the Company will provide reimbursement of the actual
cost of health insurance premiums incurred for continuation of the Executive’s existing coverage under the Consolidated Omnibus Budget Reconciliation Act (“COBRA”) until the Executive qualifies for health insurance coverage under the
Company’s plan. Such reimbursement of actual cost of health insurance premiums is subject to applicable taxes (including federal income tax at the applicable supplemental tax withholding rate) under the appropriate IRS guidelines and applicable
state tax rules and shall be made within thirty (30) days after such costs are submitted for reimbursement. The Executive must submit request for reimbursement within forty-five (45) days of incurring the cost.

(30) days of the date such costs are incurred and submitted for reimbursement. 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. 

  

	 	4.5	Change of Control Payment. If, during the term of this Agreement, there is a Change of Control (as hereafter defined) the Executive will be entitled to a lump
sum payment (the “Change of Control Payment”) within thirty (30) days of the effective date of the Change of Control (in addition to any other amounts payable to the Executive under this Agreement or otherwise) in an amount equal to
two hundred percent (200%) of: (a) the Executive’s then current Base Salary under paragraph 4.1 of this Agreement and (b) the actual bonuses paid to the Executive during the twelve (12) calendar months preceding the Change

weeks of Base Salary in a lump sum; (b) all Equity Compensation granted to the Executive under Section 4.3 of this Agreement and any Supplemental Matching Contributions to the 401(k)
Make-Up Plan shall be immediately vested; and (c) payment of any PTO pay accrued through the Termination Date. Notwithstanding the foregoing, the amount payable under clause (a) above will be reduced by any benefits payable under any
disability plans provided by the Company. The right to the foregoing compensation due under clauses (a) and (b) above is subject to the execution by the Executive or the Executive’s legal representative of the Company’s severance

beneficiary, or as applicable, the administrator of the Executive’s estate of the Company’s severance agreement which will operate as a release of all legally waivable claims against the Company. 

 

	 	6.5	 Effect of Termination. The termination of this Agreement will terminate all obligations of the Executive to render services on behalf of the
Company from and after the Termination Date, provided that the Executive will maintain the confidentiality of all information acquired by the Executive during the term of Executive’s employment in accordance with paragraph 7 of this Agreement
and the Executive shall comply with all other post employment requirements including paragraphs 7, 8, 9, 10, 11, 12, 13 and 14. Except as otherwise provided in paragraphs 4.5 and 6 of this Agreement and payment of any PTO pay accrued through the

such services to the Company as might be reasonably required to provide for the orderly termination of the Executive’s employment. Notwithstanding the foregoing and without discharging any obligations to pay compensation to the Executive under
this Agreement, after notice of the Termination, the Company may request that the Executive not provide any other services to the Company and not enter the Company’s premises before or after the Termination Date. In the event that the Executive
