 W I T N E S S E T H: 

WHEREAS, Rex Energy and Rex Operating (collectively, the “Company”) wish to have the Executive serve as
President and Chief Executive Officer of Rex Energy and President and Chief Executive Officer of Rex Operating, and, in such capacity, to be employed as an employee of Rex Operating, and the Executive wishes to be employed in such capacity;

 NOW, THEREFORE, in consideration of the premises and the respective covenants and agreements of the parties herein
contained, and intending to be legally bound hereby, the parties hereto agree as follows: 
 1. Employment and Term.

 (a) The Company hereby agrees that Rex Operating shall employ the Executive, and the Executive hereby accepts such
employment, on the terms and conditions hereinafter set forth. The parties agree that the Executive’s employment may in the future be transferred to Rex Energy, so that the Executive may be employed by either Company under this Agreement. The
period of employment of the Executive under this Agreement (the “Employment Period”) shall commence on the Effective Date and shall end on the Executive’s Date of Termination (as defined in Section 7(b) hereof) or,
if earlier, the end of the Term. Upon expiration of this Agreement at the end of the Term, after taking into account all of the extensions thereof, the Executive shall be an at-will employee of the Company. 

(b) The term of this Agreement (the “Term”) shall begin on the Effective Date and shall end on November 30,
2013; provided, that, on November 30, 2013, and each anniversary of November 30, 2013 thereafter, the Term shall be extended for one (1) additional year unless either party shall have given the other party at least ninety
(90) days prior written notice not to extend the Term or the Executive shall have incurred a termination of employment with the Company as described herein. Notwithstanding the foregoing, if one or more Changes in Control of Rex Energy occur
during the Term, the Term of this Agreement shall be automatically extended until the second anniversary of the date on which the last Change in Control of Rex Energy occurred or until the Executive’s earlier termination of employment with the
Company as described herein. 
 (c) Failure of the Company to renew the Agreement at the end of the Term shall not by itself be
considered a termination of employment by the Company or a Good Reason event, except as specifically provided herein. Notwithstanding the foregoing, in the event that the Company fails to renew the Agreement at the end of the Term and the Company
terminates the Executive’s employment without Cause within ninety (90) days following the end of the Term, the Executive shall be entitled to the benefits in Section 8(e), subject to the terms of Section 8(e) and compliance with
the covenants in Section 9. 






  
 2. Position and
Duties. 
 (a) As of the Effective Date, the Executive shall serve as President and Chief Executive Officer of Rex Energy,
and also as the President and Chief Executive Officer of Rex Operating, in which capacities the Executive shall perform the usual and customary duties of such offices, which are normally inherent in such capacities in U.S. publicly held corporations
of similar size and character as the Company. The Executive shall report to the Board of Directors of Rex Energy (the “Board”). The Executive agrees and acknowledges that, in connection with his employment relationship with
the Company, the Executive owes fiduciary duties to the Company and, if applicable, its subsidiaries, and will act accordingly. The Executive shall remain a director of Rex Energy during the Employment Period. 

(b) During the Employment Period, the Executive agrees to devote substantially his full time, attention and energies to the
Company’s business and agrees to faithfully and diligently endeavor to the best of his ability to further the best interests of the Company and its shareholders. Subject to Section 9 herein, the Executive may only serve as a director of
other companies if such service is approved in advance by the Board (which approval of one such director position will not be unreasonably withheld), so long as such service is not detrimental to the Company, does not interfere with the
Executive’s service to the Company and does not present the Executive with a conflict of interest. The Executive may invest his own assets in such form or manner as will not require his services in the daily operations of the affairs of the
companies in which such investments are made, provided that no such investment violates the Executive’s obligations under Section 2(d) or 9 herein. 
 (c) In keeping with the Executive’s fiduciary duties to the Company, the Executive agrees that he shall not, directly or indirectly, become involved in any conflict of interest, or upon discovery
thereof, allow such a conflict to continue. Moreover, the Executive agrees that he shall promptly disclose to the Board any facts which might involve any reasonable possibility of a conflict of interest, or be perceived as such. 

(d) Circumstances in which a conflict of interest on the part of the Executive would or might arise, and which should be reported
immediately by the Executive to the Board, include the following: 
 (i) ownership of a material interest in,
acting in any capacity for, or accepting directly or indirectly any payments, services or loans from a supplier, contractor, subcontractor, customer or other entity with which the Company does business; 

(ii) misuse of information or facilities to which the Executive has access in a manner which will be detrimental to the
Company’s interest; 
 (iii) disclosure or other misuse of Confidential Information (as defined in
Section 9 hereof); 
 (iv) acquiring or trading in, directly or indirectly, other properties or interests
connected with the exploration and production of oil, or the design, manufacturing, marketing or provision of other products and services in which the 

  
 2 







 
Company is engaged from time to time, including leasing of oil and gas mineral interests in those fields in which the Company has an interest or prospective interest or opportunity; 

(v) the appropriation to the Executive or the diversion to others, directly or indirectly, of any opportunity in which it
is known or could reasonably be anticipated that the Company would be interested; and 
 (vi) the ownership,
directly or indirectly, of a material interest in an enterprise in competition with the Company or its dealers and distributors or acting as a director, officer, partner, consultant, employee or agent of any enterprise which is in competition with
the Company or its dealers or distributors. 
 Notwithstanding anything to the contrary in this Section 2, it shall not be a violation of
this Agreement for the Executive to become the registered or beneficial owner of up to five percent (5%) of any class of the capital stock of a corporation registered under the Securities Exchange Act of 1934, as amended (the
“Exchange Act”), provided that the Executive does not actively participate in the business of such corporation. 
 (e) Further, the Executive covenants, warrants and represents that he shall: 
 (i) devote his full and best efforts to the fulfillment of his employment obligations; and 
 (ii) abide by any compensation clawback, recoupment or anti-hedging policy applicable to executives of the Company or its affiliates, in effect from time to time, as approved by the Board or a duly
authorized committee thereof or as required by law. 
 (f) During the Employment Period, the Executive shall receive annual
performance and compensation reviews. 
 3. Place of Performance. In connection with the Executive’s employment by
the Company, the Executive’s principal business address shall be at the Company’s current principal executive offices in State College, Pennsylvania (the “Principal Place of Employment”). Executive hereby agrees to
perform a substantial amount of his duties at the Principal Place of Employment, and understands and agrees that he will be required to travel from time to time for business purposes. 

4. Compensation and Related Matters. 
 (a) Base Salary. During the Employment Period, the Company shall pay the Executive an annual base salary (“Base Salary”) in an amount that shall be established from time to
time by the Compensation Committee of the Board (the “Compensation Committee”), payable in approximately equal installments in accordance with the Company’s customary payroll practices, which is currently bi-weekly
payments. The Base Salary shall be set initially at four hundred and ten thousand dollars ($410,000). The Compensation Committee shall review the Executive’s Base Salary at least annually thereafter during the Employment Period. The


  
 3 







 
Executive’s Base Salary may be increased but (i) may not be materially reduced (as defined in Section 6(d)(iv) below) during any portion of the Employment Period preceding a Change
in Control and (ii) may not be reduced during any portion of the Employment Period following a Change in Control. 
 (b)
Bonuses. 
 (i) Sign-on Bonus. On the first day of employment, the Company shall pay Executive a
sign-on bonus of $136,000. 
 (ii) Annual Bonus. During the Employment Period, the Executive shall be
eligible to participate in the Annual Executive Incentive Plan, or any successor plan thereto (the “Annual Incentive Plan”). The bonus opportunity afforded the Executive under the Annual Incentive Plan may vary from year to
year and any bonus earned, if any, thereunder (the “Annual Bonus”) shall be paid at a time and in a manner consistent with the Company’s customary practices and in accordance with the terms of the Annual Incentive Plan.
The Executive’s target Annual Bonus percentage will be initially set at fifty-five percent (55%) of the Executive’s Base Salary, which shall be prorated for the 2010 fiscal year based on salary actually earned in 2010 after the
Effective Date; provided, however, that the 2010 Annual Bonus shall be no less than $12,000, payable in two equal installments on the first business day in November after the Effective Date and December 1, 2010. Notwithstanding the foregoing,
if the Company pays the Executive a director’s fee in November 2010, no portion of the 2010 guaranteed bonus will be paid in November 2010, and the 2010 guaranteed bonus amount shall be reduced to $6,000, payable on December 1, 2010. For
fiscal year 2011, the Executive shall be guaranteed an Annual Bonus at a minimum of $72,000, payable in equal installments on the first business day of each of month of 2011, which amounts shall be credited against any actual Annual Bonus payout for
fiscal year 2011. Except as otherwise provided for herein, the Executive’s bonus levels established under the Annual Incentive Plan, if any, will be contingent upon the Company achieving predetermined performance goals and approval by the
Compensation Committee. 
 (c) Equity-Based, Long-Term Cash and Performance-Based Compensation Awards. 

(i) Initial Grants. On the Effective Date, Executive shall receive the following grants determined as follows:

 (1) Rex Energy will grant to the Executive a number of stock options to purchase shares of Rex Energy common
stock (“Common Stock”) having an aggregate expense to the Company over the vesting period of the options of $282,444 on the date of grant determined using the Fair Market Value (as defined in Rex Energy’s 2007 Long-Term
Incentive Plan) and the accounting expense methodology that the Company has consistently used in the past in accordance with U.S. generally accepted accounting principles (the “Options”). The number of shares of Common Stock
subject to the Options will be determined by dividing $282,444 by the value of an option to purchase a share of 

  
 4 







 
Common Stock on the date of grant utilizing this past expense methodology. The Options will have an exercise price equal to the Fair Market Value of share of Common Stock on the date of grant,
will vest and become exercisable as to 50% on each of the first and second anniversaries of the date of grant and will have a term of five years. The Options will be granted by the Compensation Committee under and governed by the Rex Energy’s
2007 Long-Term Incentive Plan and, except as modified by this Section 4(c)(i)(1), shall be issued pursuant to an agreement in the form of the Nonqualified Stock Option Award Agreement filed as Exhibit 10.25 to Rex Energy’s Annual Report on
Form 10-K for the year ended December 31, 2007. 
 (2) Rex Energy will grant to Executive restricted shares
of Common Stock (“Restricted Shares”) at a total expense to the Company at BOE Target Goal and DSCF ps Target Goal (as those terms are defined in the Form of Award Agreement (as defined below)) of $564,889 over two years. The
number of Restricted Shares granted will be determined by multiplying $564,889 by two and dividing by the Fair Market Value of a share of Common Stock on the date of grant. The Restricted Shares will vest on December 31, 2012, subject to the
Company’s attainment of the applicable performance targets. Notwithstanding the foregoing vesting schedule, the Executive shall be eligible to receive 50% of the Restricted Shares that vest as of December 31, 2012, provided he remains
employed with the Company from the grant date through December 31, 2011 and 100% of the Restricted Shares that vest as of December 31, 2012, provided he remains employed with the Company from the grant date through December 31, 2012.
By March 15, 2013, the Compensation Committee shall certify as to whether and to what extent the applicable performance targets for the two year period ending December 31, 2012 have been satisfied. The Restricted Shares will be granted by
the Compensation Committee under and governed by the Rex Energy’s 2007 Long-Term Incentive Plan and, except as modified by this Section 4(c)(i)(2), shall be issued in an agreement in the form of the Restricted Stock Award Agreement filed
as Exhibit 10.1 to Rex Energy’s Current Report on Form 8-K file with the Securities and Exchange Commission on March 31, 2010 (the “Form of Award Agreement”). For the purposes of the Restricted Shares grant
agreement, the Company has informed Executive of his performance targets. 
 (ii) Subsequent Grants.
Starting in fiscal year 2011, during the Employment Period, the Executive shall be eligible to receive equity-based and/or long-term cash compensation awards and performance awards as approved by the Compensation Committee. Executive’s initial
annual target award percentage is expected to be at 120% of Base Salary, and initial annual overachievement award cap is expected to be at 240% of Base Salary, subject to adjustment by the Compensation Committee in its sole and absolute discretion.

incurred in connection with entering into this Agreement, up to a maximum of ten thousand dollars ($10,000), and all reasonable business 

  
 5 







 
expenses incurred during the Employment Period by the Executive in performing services hereunder, including all expenses of travel and living expenses while away from home on business of the
Company or at the request of the Company, provided that, in each case, such expenses are incurred and accounted for in accordance with the policies and procedures established by the Company. All reimbursements with respect to expenses incurred in a
particular taxable year shall be made no later than the end of the Executive’s taxable year following the taxable year in which the expenses were incurred, subject to the Executive’s timely presentment of the applicable receipts to the
Company in accordance with the Company’s expense reimbursement policies and procedures. The amount of reimbursable expenses incurred in one taxable year of the Executive shall not affect the amount of reimbursable expenses in a different
taxable year, and any such reimbursement shall not be subject to liquidation or exchange for another benefit. 
 (e) Other
Benefits. During the Employment Period, the Executive shall be entitled to participate in all of the employee benefit plans and arrangements made available by the Company to its other senior executive officers, subject to and on a basis

 6 







 
corporations, and in one or more executive positions of the Company or any of its subsidiaries; provided, that the Executive shall be indemnified for serving in any and all such capacities on a
basis no less favorable than is currently or may be provided to any other director of the Company or any of its subsidiaries, or in connection with any such executive position, as the case may be. This indemnity is in addition to and not in
replacement of the Company’s obligations to provide indemnity pursuant to Section 10 hereof.

of which is the number of days in the fiscal year before the Date of Termination and the denominator is the number of days in the fiscal year. If the Executive’s employment terminates by reason of death, the separation payment shall be paid on
the sixtieth (60th) day following the Date of
Termination, subject to compliance with Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”). If the Executive’s employment terminates by reason of Disability, the separation payment shall be
paid on the first business day following the end of the six (6) month period following the Date of Termination (the “Commencement Date”), subject to compliance with Section 409A of the Code. The Executive shall not
be entitled to any other payments under the annual cash bonus plan with respect to the fiscal year in which the Date of Termination for death or Disability occurs. 
 (c) By the Company for Cause. If during the Term the Executive’s employment is terminated by the Company for Cause pursuant to Section 6(c) hereof, the Company shall pay to the Executive
the Accrued Obligation. Following such payment, the Company shall have no further obligations to the Executive other than as may be required by law or the terms of an employee benefit plan of the Company. 

(d) By the Executive without Good Reason. If during the Term the Executive terminates his employment for any reason other than
Good Reason, the Company shall pay to the Executive the Accrued Obligation. Following such payment, the Company shall have no further obligations to the Executive other than as may be required by law or the terms of an employee benefit plan of the
Company. The Executive shall not have breached this Agreement merely because he terminates his employment for any reason other than Good Reason. 
 (e) By the Company without Cause or by the Executive for Good Reason. If, (x) during the Term, the Executive’s employment is terminated by the Company other than for Cause, death or
Disability or the Executive terminates employment for Good Reason, or (y) the Company fails to renew the Agreement at the end of the Term and the Company terminates the Executive’s employment without Cause within ninety (90) days
following the end of the Term as set forth in Section 1, then the Company shall pay to the Executive the Accrued Obligation and, subject to the Executive executing and not revoking a Release as described in Section 8(e)(v) and provided
that the Executive complies with the covenants set forth in Section 9: 
 (i) If the Date of Termination
occurs before a Change in Control of Rex Energy or after the twenty-four (24) month period following such Change in Control of Rex Energy: 
 (A) The Company shall pay the Executive severance pay equal to the Executive’s monthly Base Salary (at the rate in effect as of the Date of Termination) for the eighteen (18) month period
following the Date of Termination. The severance payments will begin on the Commencement 

  
 13 








 
Date, and the first payment will include the first six (6) monthly installments, subject to compliance with Section 409A of the Code. The severance payments will continue in
installments in accordance with the Company’s regular payroll practices for the remainder of the eighteen (18) month period following the Date of Termination, subject to compliance with Section 409A; provided, however, that if the
Executive is an employee or independent contractor of a subsequent employer after the end of the twelve (12) month period following the Date of Termination, the severance payments shall immediately cease as of the later of the end of the twelve
(12) month period or the date the Executive begins providing services to a subsequent employer and the Executive shall have no right to continued severance payments pursuant to this Section 8(e)(i)(A) thereafter. The Executive agrees to
notify the Company that he is providing services to a subsequent employer immediately upon commencement of such services. Any unvested equity awards granted pursuant to Section 4(c)(i) above and the first equity award granted in 2011 pursuant
to Section 4(c)(ii) above that are held by the Executive shall continue to vest following the Date of Termination until the end of the period for which severance payments are payable. 

(B) The Company shall pay the Executive a lump sum cash payment equal to the Executive’s annual cash bonus for the
fiscal year of the Company in which the Date of Termination occurs, prorated based on service for the year of termination. For this purpose, the annual bonus shall be calculated as the annual cash bonus that the Executive would have received had the
Executive remained employed through the end of such year, based on the Company’s achievement of the applicable performance goals, and multiplied by a fraction, the numerator of which is the number of days in the fiscal year before the Date of
Termination and the denominator is the number of days in the fiscal year. The bonus payment shall be paid when bonuses are paid to other executives participating in the Annual Incentive Plan or, if later, on the Commencement Date. 

(ii) Notwithstanding the provisions of Section 8(e)(i), if the Date of Termination occurs on or during the
twenty-four (24) month period following a Change in Control of Rex Energy: 
 (A) The Company shall pay to
the Executive severance pay equal to twenty-four (24) months of the Executive’s monthly Base Salary (at the rate in effect as of the Date of Termination) in a lump sum cash payment on the Commencement Date, subject to compliance with
Section 409A of the Code.  
 (B) The Company shall pay to the Executive a lump sum cash separation
payment equal to the Executive’s target annual cash bonus for the fiscal year of the Company in which the Date of Termination occurs, prorated based on service for the year of termination. The pro rated bonus


  
 14 








 
shall be determined by multiplying the target bonus by a fraction, the numerator of which is the number of days in the fiscal year before the Date of Termination and the denominator is the number
of days in the fiscal year. The separation payment shall be paid on the Commencement Date, subject to compliance with Section 409A of the Code. 
 (C) Notwithstanding any other provisions of this Agreement, in the event that any payment or benefit received or to be received by the Executive in connection with a Change in Control (whether pursuant to
the terms of this Agreement or any other plan, arrangement or agreement with the Company, any person whose actions result in a Change in Control or any person affiliated with the Company or such person such as to require attribution of stock
ownership between the parties under Section 318(a) of the Code) (all such payments and benefits, including the severance payments described in Section 8 (the “Severance Payments”), being hereinafter called
“Total Payments”) would be subject (in whole or part), to any excise tax imposed under Section 4999 of the Code, then, after taking into account any reduction in the Total Payments provided by reason of Section 280G
of the Code in such other plan, arrangement or agreement, the cash Severance Payments shall first be reduced, and the noncash Severance Payments shall thereafter be reduced, to the extent necessary so that no portion of the Total Payments is subject
to the Excise Tax but only if (A) the net amount of such Total Payments, as so reduced (and after subtracting the net amount of federal, state and local income taxes on such reduced Total Payments) is greater than or equal to (B) the net
amount of such Total Payments without such reduction (but after subtracting the net amount of federal, state and local income taxes on such Total Payments and the amount of Excise Tax to which the Executive would be subject in respect of such
unreduced Total Payments). For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise Tax: 
 (w) No portion of the Total Payments the receipt or enjoyment of which the Executive shall have waived at such time and in such manner as not to constitute a “payment” within the meaning of
Section 280G(b) of the Code shall be taken into account; 
 (x) No portion of the Total Payments shall
be taken into account which, in the opinion of tax counsel selected by the Company before the Change in Control (“Tax Counsel”) does not constitute a “parachute payment” within the meaning of Section 280G(b)(2)
of the Code (including by reason of Section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax, no portion of such Total Payments shall be taken into account which, in the opinion of Tax Counsel, constitutes reasonable compensation
for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in excess of the base amount (as defined in Section 280G(b)(3) of the Code) allocable to such reasonable compensation; and 

  
 15 








  
 (y)
The value of any non-cash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the accounting firm which was, immediately prior to the Change of Control, the Company’s registered public accounting
firm (the “Auditor”) in accordance with the principles of Sections 280G(d)(3) and (4) of the Code. 
 (z) At the time that payments are made under this Agreement, the Company shall provide the Executive with a copy of the Auditor’s calculations setting forth the manner in which such payments were
calculated and the basis for such calculations including, without limitation, any written opinions the Company has received from Tax Counsel or the Auditor with respect to the calculations. 

(iii) The following payments will be made without regard to whether a Change in Control has occurred: 

(A) For the applicable Severance Period, as defined below, the Company shall arrange to provide the
Executive and his dependents medical, dental, health, hospital insurance benefits substantially similar to those provided to the Executive and his dependents immediately prior to the Date of Termination, as such benefit plans may be modified by the
Company from time to time for similarly situated active employees (at no greater cost to the Executive than such cost to the Executive in effect immediately prior to the Date of Termination, or, if greater, the cost to similarly situated active
employees of the Company under the applicable group health plans of the Company), provided that the Executive timely elects coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) and
pays the COBRA premiums for the full cost of the continued coverage. The Executive shall be responsible for paying the full COBRA cost of such coverage, and the Company shall reimburse the Executive monthly for the amount equal to the
Executive’s monthly COBRA cost, less the employee portion of the premium that the Executive would have paid had the Executive continued employment with the Company; provided that reimbursement of the COBRA cost shall be discontinued prior to
the end of the Severance Period if the Executive elects to discontinue COBRA coverage, if the Executive fails to pay the applicable COBRA costs or in accordance with Section 8(e)(iv) below. The COBRA reimbursement payments shall be paid monthly
on the first payroll date of each calendar month, beginning on the sixtieth (60th) day following the Date of Termination, subject to compliance with Section 409A of the Code. The first payment (on the sixtieth (60th) day) will include the first two (2) months of COBRA reimbursements. The Executive understands and agrees
that for purposes of determining the remaining period of the Executive’s COBRA continuation coverage after the end of the Severance Period, the Executive’s “qualifying event” shall be deemed to have occurred on the Date of
Termination. 

  
 16 








  
 (B) On
the Commencement Date, the Company shall pay the Executive a lump sum amount equivalent to the product of the monthly basic life insurance premium applicable to the Executive’s basic life insurance coverage immediately prior to the Date of
Termination times the number of months in the applicable Severance Period, subject to compliance with Section 409A of the Code. The Executive may, at his option, convert his basic life insurance coverage to an individual policy after the Date
of Termination by completing the forms required by the Company for this purpose. 
 (C) For purposes of this
Agreement, “Severance Period” shall mean: 
 (x) the eighteen (18) month period
following the Date of Termination if the Executive’s employment is terminated by the Company without Cause or by the Executive for Good Reason, in either case before a Change in Control of Rex Energy or after the twenty-four (24) month
period following such Change in Control of Rex Energy, or 
 (y) the twenty-four (24) month period
following the Date of Termination if the Executive’s employment is terminated by the Company without Cause or by the Executive for Good Reason, in either case within the twenty-four (24) month period following a Change in Control of Rex
Energy. 
 (iv) Subject to the Executive’s group health plan coverage continuation rights under COBRA, the
benefits described in Section 8(e)(iii) shall be reduced to the extent benefits of the same type are received by or made available to the Executive during such period, and reimbursements under Section 8(e)(iii) shall cease if the Executive
becomes eligible to receive benefits of the same type as described in Section 8(e)(iii). The Executive shall have the obligation to notify the Company that he is entitled to or receiving such benefits. The Company agrees that, if the
Executive’s employment with the Company terminates for any reason during the Term, the Executive is not required to seek other employment or to attempt in any way to reduce any amounts payable to the Executive by the Company pursuant to this
Section 8. Further, except with respect to the benefits provided pursuant to Section 8(e)(iii) above, the amount of any payment or benefit provided for in this Agreement shall not be reduced by any compensation earned by the Executive as
the result of employment by another employer, by retirement benefits, or by offset against any amount claimed to be owed by the Executive to the Company. 
 (v) Notwithstanding the foregoing, all payments to the Executive under this Section 8 (other than Accrued Obligations) are contingent upon the


  
 17 








 
Executive’s execution and non-revocation of a release with terms substantially in the form of Exhibit A hereto (the “Release”) within sixty (60) days
following the Executive’s Date of Termination. In consideration of the benefits and compensation which may be awarded to the Executive pursuant to Section 8 of this Agreement, the Executive hereby agrees to execute and be bound by the
Release, as a condition precedent to receiving such benefits and compensation. No severance payments will be paid to the Executive if the Executive does not execute, or if the Executive revokes, the Release. Notwithstanding any provision of this
Agreement to the contrary, in order to comply with Section 409A of the Code, in no event shall the timing of the Executive’s execution of the Release, directly or indirectly, result in the Executive designating the calendar year of
payment, and if a payment that is subject to execution of the Release could be made in more than one taxable year, payment shall be made in the later taxable year. 

(vi) Notwithstanding the foregoing, if a Change in Control of Rex Energy does not meet the requirements of a “change
in control event” under Section 409A of the Code, then the amounts to be paid under Section 8(e)(ii) above will be paid in the forms and at the times set forth in Section 8(e)(i) above, if and as required by Section 409A.

 (f) The applicable grant agreements shall govern the treatment of the Executive’s outstanding options, stock
appreciation rights, restricted stock and other equity grants with respect to Rex Energy stock in the event of a Change in Control. 
 9. Confidential Information; Non-Competition; Non-Solicitation; Non-Disparagement. 
 (a) Confidential Information. 
 (i) The Executive shall hold
in a fiduciary capacity for the benefit of the Company all trade secrets, confidential information, and knowledge or data relating to the Company or its subsidiaries and their businesses, which shall have been obtained by the Executive during the
Executive’s employment by the Company and which shall not have been or hereafter become public knowledge (other than by acts by the Executive or representatives of the Executive, in each case, in violation of this Agreement) (hereinafter being
collectively referred to as “Confidential Information”). For the avoidance of doubt, Confidential Information shall not include information that becomes available to the public other than as a result of a disclosure by the
Executive or that becomes available to the Executive from a source other than the Company or any of its subsidiaries or any of their respective directors, officers, employees, agents or advisors, provided, that such source is not known by the
Executive to be bound by a confidentiality agreement with or other obligation of secrecy to the Company or any of its subsidiaries. 
 (ii) The Executive shall not, without the prior written consent of the Company or as may otherwise be required by law or legal process, communicate or divulge any such trade secrets, information,
knowledge or data to anyone other than the Company and those designated by the Company. Any termination of the Executive’s employment or of this Agreement shall have no effect on the continuing operation of this


  
 18 








 
Section 9(a). The Executive agrees to return all Confidential Information, including all photocopies, extracts and summaries thereof, and any such information stored electronically on tapes,
computer disks or in any other manner to the Company at any time upon request by the Company and upon the termination of his employment hereunder for any reason. 
 (b) Non-Competition. 
 (i) During the Employment Period and
the Restricted Period, as defined below, the Executive shall not, within the Restricted Territory, as defined below, engage in Competition, as defined below, with respect to the Company or any of its subsidiaries; provided, that it shall not be a
violation of this Section 9(b) for the Executive to become the registered or beneficial owner of up to five percent (5%) of any class of the capital stock of a corporation registered under the Exchange Act as long as the Executive does not
actively participate in the business of such corporation until such time as this covenant expires. 
 (ii) For
purposes of this Agreement, the “Restricted Period” means the applicable period in clause (A) if the Date of Termination occurs during the Term of the Agreement, or the applicable period in clause (B), (C) or
(D) if the Date of Termination occurs after the end of the Term: 
 (A) The Restricted Period is the
eighteen (18) month period following the Executive’s Date of Termination during the Term for any reason. 
 (B) In the event the Company elects not to renew the Agreement at the end of the Term and the Executive receives severance pay as a result of a termination without Cause under Section 1(c) or a
termination for Good Reason under Section 6(d)(ii)(4), the Restricted Period is the applicable period described in clause (A) above. 
 (C) If clause (B) does not apply, in the event the Company or the Executive elects not to renew the Agreement at the end of the Term, and during the eighteen (18) month period following the end
of the Term the Executive’s employment terminates for any reason other than Cause, the Company will either: 
 (xx) within thirty (30) days after the Date of Termination, offer in writing to provide the Executive with severance pay equal to the Executive’s Base Salary for all or part of the remainder of
the eighteen (18) month period following the end of the Term, subject to the Executive executing and not revoking a Release, in which case the Restricted Period shall be the remainder of the eighteen (18) month period following the end of
the Term (or, if the Company only offers to provide severance pay for a portion of the remainder of the eighteen (18) month period following the end of the Term, the Restricted Period shall be such portion of the period for which the Company
offers severance pay), or 

  
 19 








  
 (yy)
advise the Executive in writing that the Restricted Period shall not apply after the Date of Termination. 
 The severance pay
will be paid at the same time and in the same form as would have applied if the severance pay had been paid under Section 8(e)(i)(A) or Section 8(e)(ii)(A) above, depending on when the Date of Termination occurs (i.e. installments over the
remainder of the eighteen (18) month period described in (xx) above or a lump sum, depending on when the Date of Termination occurs). If the Company offers to provide such severance pay but the Executive does not execute the Release, or
revokes the Release, the Restricted Period will nevertheless run for the remainder of the eighteen (18) month period after the end of the Term, but no severance payments will be paid to the Executive. 

(D) In the event the Company or the Executive elects not to renew the Agreement at the end of the Term, and during the
eighteen (18) month period following the end of the Term the Executive’s employment terminates for Cause, the Restricted Period shall be the applicable period described in clause (A) above, and no severance pay shall be provided.

 (iii) For purposes of this Agreement, “Restricted Territory” means anywhere within a
ten (10) mile radius of any area of mutual interest, evidenced by a written contractual obligation, of the Company or its subsidiaries or any oil or gas property in which the Company or any of its subsidiaries has an interest, or is actually
pursuing or contemplating (as described below) an interest, as of the Date of Termination. The Company or a subsidiary will be considered to be contemplating an interest in property for purposes of this subsection (iii) if the Executive knows
that the Company or a subsidiary is actively contemplating an interest in the property within the 90-day period preceding the Date of Termination, as evidenced by written or electronic correspondence or records. 

(iv) For purposes of this Agreement, “Competition” by the Executive means the Executive’s
engaging in, or otherwise directly or indirectly being employed by or acting as a consultant or lender to, or being a director, officer, employee, principal, agent, stockholder, member, owner or partner of, or permitting his name to be used in
connection with the activities of any other business or organization which competes, directly or indirectly, with the business of the Company or its subsidiaries as the same shall be constituted at any time during the Term. 

(v) The Executive may request that the Board waive the restrictions under this Section 9(b) with respect to the
Executive’s prospective employment with an entity engaged in Competition if the Executive’s work will clearly not relate in any way to the Restricted Territory. The Board shall have sole discretion to determine whether such a waiver will
be allowed and the terms and conditions of any such waiver. 

  
 20 








  
 (c)
Non-Solicitation. During the eighteen (18) month period following the Date of Termination for any reason, if the Date of Termination occurs during the Term or within eighteen (18) months after any non-renewal of the Term, the
Executive agrees that the Executive will not, directly or indirectly, for his benefit or for the benefit of any other person, firm or entity, do any of the following: 

(i) solicit, from any customer that is doing business with the Company or any of its subsidiaries as of the Date of
Termination and is known to Executive, any business of the same or of a similar nature to the business of the Company or its subsidiaries with such customer; 
 (ii) solicit, from any potential customer of the Company or its subsidiaries that is known to the Executive, any business of the same or of a similar nature to that which has been the subject of a known
written or oral bid, offer or proposal by the Company or its subsidiaries, or of substantial preparation with a view to making such a bid, proposal or offer, within six (6) months prior to the Date of Termination; 

(iii) excluding advertisements in mainstream media, solicit the employment or services of any person who was known to be
employed by or was a known consultant to the Company or its subsidiaries upon the Date of Termination, or within six (6) months prior thereto, provided that it shall not be a breach of this Section 9(c)(iii) to solicit or engage a
consultant if the consultant’s services do not interfere with the consultant’s services to the Company or cause the consultant to engage in Competition in the Restricted Territory; or 

(iv) otherwise knowingly interfere with the business or accounts of the Company or its subsidiaries. 

(d) Non-Disparagement. The Executive agrees, and the Company agrees to instruct its officers and directors, not to make any
derogatory, disparaging or false statements intended to harm the business or personal reputation of the other party to this Agreement and, in the case of the Company, of any related companies or their officers and employees. 

(e) Agreements with respect to Covenants. The Executive and the Company agree and acknowledge that the Company is providing the
employment, compensation and benefits under this Agreement in consideration for the Executive’s covenants under this Section 9. The Executive and the Company agree and acknowledge that the Company has a substantial and legitimate interest
in protecting the Company’s and its subsidiaries’ Confidential Information and goodwill. The Executive and the Company further agree and acknowledge that the provisions of this Section 9 are reasonably necessary to protect the
Company’s and its subsidiaries’ legitimate business interests and are designed to protect the Company’s and its subsidiaries’ Confidential Information and goodwill. The Executive agrees that the scope of the restrictions as to
time, geographic area, and scope of activity in this Section 9 are reasonably necessary for the protection of the Company’s and its subsidiaries’ legitimate business interests and are not oppressive or injurious to the public
interest. The Executive and the Company agree that in the event of a breach or threatened breach of any of the provisions of this Section 9, the Company or the Executive, as applicable, shall be entitled to injunctive relief against the


  
 21 








 
Executive’s or the Company’s activities, as applicable, to the extent allowed by law, and the Executive and the Company waive any requirement for the posting of any bond by the Company
or the Executive, as applicable, in connection with such action. The Executive further agrees that any breach or threatened breach of any of the provisions of Section 9(a) would cause injury to the Company for which monetary damages alone would
not be a sufficient remedy. 
 (f) Permitted Disclosure. Nothing in this Agreement shall prohibit or restrict the
Executive or the Company from (i) making any disclosure of relevant and necessary information or documents in any action, investigation or proceeding, as required by law or legal process; or (ii) participating, cooperating, or testifying
in any action, investigation, or proceeding with, or providing information to, any governmental agency or legislative body, any self-regulatory organization, or the Company’s Legal Department, provided that, to the extent permitted by law, upon
the Executive’s receipt of any subpoena, court order or other legal process compelling the disclosure of any such information, documents, or testimony, the Executive shall give prompt prior written notice to the Company, and the Executive will
make no disclosure until the Company has had a reasonable opportunity to contest the right of the requesting person or entity to such disclosure. 
 10. Indemnification; Insurance. The Company shall indemnify the Executive to the fullest extent permitted by the laws of the Company’s state of incorporation in effect at the time and the
certificate of incorporation and by-laws of the Company. The Executive will be entitled to any insurance policies the Company may elect to maintain generally for the benefit of officers and directors of the Company and its subsidiaries against all
costs, charges and expenses incurred in connection with any action, suit or proceeding to which the Executive may be made a party by reason of being a director or officer of the Company or its subsidiaries. 

11. Successors Binding Agreement. 
 (a) Company’s Successors. The Company may require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or
assets of the Company to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. As used in this Agreement,
“Company” shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which executes and delivers the agreement provided for in this Section 11 or which otherwise becomes
bound by all the terms and provisions of this Agreement by operation of law. 
 (b) Executive’s Successors. This
Agreement and all rights of the Executive hereunder shall inure to the benefit of and be enforceable by the Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If the
Executive should die while any amounts would still be payable to him hereunder if he had continued to live, all such amounts unless otherwise provided herein shall be paid in accordance with the terms of this Agreement to the Executive’s
devisee, legatee or other designee or, if there is no such designee, to the Executive’s estate.

such other address as either party may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon receipt. 

13. Amendment or Modification; Waiver. No provisions of this Agreement may be modified, waived or discharged unless such waiver,
modification or discharge is agreed to in writing signed by the Executive and such officer or director of the Company as may be specifically designated by the Board or the Compensation Committee. No waiver by either party hereto at any time of any
breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or
subsequent time. No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party which are not set forth expressly in Agreement. 

14. Governing Law. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of
the Commonwealth of Pennsylvania without regard to its conflicts of law principles. 
 15. Miscellaneous. All references
to sections of any statute shall be deemed also to refer to any successor provisions to such sections. The respective rights and obligations of the parties hereunder shall survive the termination of the Term to the extent necessary to preserve


  
 23 








 
such rights and obligations, including, without limitation, Sections 8, 9, 10 and 11. The Executive shall not be a participant in and shall not be entitled to receive benefits pursuant to any
other severance plan, program, policy or arrangement of the Company. 
 16. Severability. The invalidity or
unenforceability of any provision or provisions of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect throughout the Term. Should any one or more of
the provisions of this Agreement be held to be excessive or unreasonable as to duration, geographical scope or activity, then that provision shall be construed by limiting and reducing it so as to be reasonable and enforceable to the extent
compatible with the applicable law. 
 17. Counterparts. This Agreement may be executed in one or more counterparts, each
of which shall be deemed to be an original but all of which together will constitute one and the same instrument. 
 18.
Withholding. All payments under this Agreement shall be made subject to applicable tax withholding, and the Company may withhold from any amounts payable to the Executive relating to the Executive’s employment with the Company such
federal, state, local and foreign taxes as shall be required to be withheld pursuant to any applicable law or regulation. The Executive shall bear all expense of, and be solely responsible for, all federal, state, local and foreign taxes due with
respect to any payment received under this Agreement. 
 19. Deferred Compensation. Notwithstanding any provision of this
Agreement to the contrary, this Agreement is intended to meet the requirements of Section 409A of the Code to the extent applicable, the parties intend to administer this Agreement in a manner that is consistent with those requirements or an
exception thereto, and this Agreement shall be construed and interpreted in accordance with such intent. If and to the extent applicable, severance benefits shall be paid first under the “short-term deferral exception” and then under the
“separation pay exception” of Section 409A, and any payments that are considered deferred compensation under Section 409A and that are paid to a “specified employee” (as defined in Section 409A of the Code) upon
separation from service shall be subject to a six (6) month delay, if required by Section 409A. If required by Section 409A, any amounts otherwise payable during the six (6) month period that commences on and follows the
Executive’s Date of Termination shall be paid in one lump sum amount on the first business day following the six (6) month period following the Executive’s Date of Termination (or within thirty (30) days of the Executive’s
death, if earlier). For purposes of Section 409A of the Code, all payments to be made upon a termination of employment under this Agreement may only be made upon a “separation from service” (within the meaning of such term under
Section 409A of the Code). Each payment made under this Agreement shall be treated as a separate payment and the right to a series of installment payments shall be treated as the right to a series of separate payments. In no event shall the
Executive, directly or indirectly, designate the calendar year of a payment. All reimbursements under this Agreement shall be provided in a manner that complies with Section 409A of the Code, if applicable. If required by regulations or other
guidance issued under Section 409A of the Code or a court of competent jurisdiction, the provisions regarding payments hereunder shall be amended to provide for such payments to be made at the time allowed under such regulations, guidance or
authority that most closely achieves the intent of this Agreement.

 20. Entire

mental injury, damage to reputation, and any other injury, loss, damage or expense or any other legal or equitable remedy of any kind whatsoever. This release covers both claims that Employee knows about and those he may not know about. This

reemployment or to recovery of any money from the Company resulting from any lawsuit, charge or complaint raising any claims that are released in Section 1. Employee understands that he is not waiving the right to test the knowing and voluntary
nature of this release agreement in court.

 EXHIBIT B

 MOVING ASSISTANCE 
 Executive expects to move his residence from Overland Park, Kansas to the State College, Pennsylvania area after the close of the 2010-11 school year but no later than the beginning of the 2011-12 school
year for his minor son (the “Outside Move Date”). The Company agrees to pay Executive reasonable coach air fare, car rental, travel and living expenses for Executive to travel weekly between these locations until Executive
completes the move of his residence and reasonable coach air fare for Executive’s family to visit Executive in State College on occasion. If Executive has not sold Executive’s residence in Overland Park, Kansas on or before the Outside
Move Date, the Compensation Committee may either authorize the Company to purchase Executive’s home (for ultimate resale by the Company) or extend the Outside Move Date a month at a time. 

The Company shall reimburse Executive for the difference between $645,000 and the amount for which Executive sells his residence in Overland Park, Kansas
that is below $645,000. Executive will not agree to a sales contract that is more than $40,000 below $645,000 without the approval of the Compensation Committee. Upon identifying a buyer, the Company may require Executive to sell Executive’s
home to the Company or its designee (who then may resell to a buyer). The Company shall pay Executive’s real estate selling commission on Executive’s home and normal closing costs on the purchase of his new home not to include discount
points and mortgage insurance. The closing statement must specify the loan origination fee and loan discount points separately. The reimbursements described in this paragraph shall be paid no later than 15 days after the applicable date upon which
Executive may claim the reimbursement (but in no event later than the date permitted under Section 409A of the Code); provided that no payment will be made if Executive terminates employment without Good Reason or Executive’s employment is
terminated for Cause before the date of the expense to be reimbursed. 
 The Company shall pay Executive the reasonable cost of packing, moving
and unpacking Executive’s household goods and automobiles to a new residence in the State College, Pennsylvania area, including any temporary storage. 
 To the extent any of these expenses in Exhibit B are taxable to Executive, the Company agrees to pay to the Executive an additional payment in an amount that after payment by the Executive of all taxes
imposed upon the payments on a grossed-up basis, the Executive retains an amount equal to the expenses prior to the taxes. The tax gross up payments shall be made at the same time as the underlying expenses are paid. 

The Compensation Committee shall monitor these expenses in Exhibit B on a monthly basis.
