 5. Confidential Information; No Solicitation; Non-Competition. 

(a) All confidential information or trade secrets which you may obtain relating to the business of the Company and its affiliates shall
not be used by you or published, disclosed, or made accessible by you to any other person, firm, or corporation except in connection with the business, and for the benefit, of the Company and its affiliates. You shall not, until two (2) years
after your employment with the Company has terminated, for yourself or on behalf of any other person, firm, partnership, corporation, or other entity, directly or indirectly solicit or hire, or attempt to solicit or hire, any employee of the Company
or its affiliates (or any person employed by the Company or its affiliates within the six (6)-month period prior to such solicitation or hire or attempt to solicit or hire) away from the Company or its affiliates. 

(b) In the event that your employment is terminated by ATLS for Cause, or is terminated by you for any reason other than for Good Reason
(each as defined in Section 6 hereof), then you shall not, until eighteen (18) months after the termination of your employment, for whatever reason, for yourself or on behalf of any other person, firm, partnership, corporation, or other
entity, directly or indirectly engage in any natural gas pipeline and/or processing business in the continental United States. For purposes of this clause 5(b), “to engage” shall include your acting as an owner (of more than 5%), employee,
director or officer of an entity so engaged. 
 (c) You acknowledge that the restrictions contained in this Section 5 are,
in view of the nature of the business of the Company, reasonable and necessary to protect the legitimate interests of the Company, and that any violation of any provision of this Section will result in irreparable injury to the Company. You also
acknowledge that in the event of any such violation, the Company shall be entitled to preliminary and permanent injunctive relief, without the necessity of proving actual damages or posting a bond, and to an equitable accounting of all earnings,
profits and other benefits arising from any such violation, which rights shall be cumulative and in addition to any other rights or remedies to which the Company may be entitled. You agree that in the event of any such violation, an action may be
commenced by the Company for any such preliminary and permanent injunctive relief and other equitable relief in any federal or state court of competent jurisdiction sitting in Pennsylvania or in any other court of competent jurisdiction. You hereby
waive, to the fullest extent permitted by law, any objection that you may now or hereafter have to such jurisdiction or to the laying of the venue of any such suit, action or proceeding brought in such a court and any claim that such suit, action or
proceeding has been brought in an inconvenient forum. You agree that effective service of process may be made upon you by mail under the notice provisions contained in Section 10 hereof. 

6. Termination. Notwithstanding anything herein to the contrary, your employment shall terminate as a result of any of the
following events: 
 (a) Your death; 
 (b) Termination by ATLS for Cause. “Cause” shall encompass any of the following: (i) you have committed any demonstrable and material act of fraud; (ii) illegal or gross
misconduct by you that is willful and results in damage to the business or reputation of the 

  
 3 








 
Company; (iii) you are charged with a felony; (iv) the continued failure of you to substantially to perform your duties under this Agreement (other than as a result of physical or
mental illness or injury) after ATLS delivers you a written demand for substantial performance that specifically identifies, with reasonable opportunity to cure, the manner in which ATLS believes that you have not substantially performed your
duties; or (v) you have failed to follow reasonable written directions of ATLS which are consistent with your duties hereunder and not in violation of applicable law. ATLS’s termination of your employment for Cause shall be effected by
ATLS providing you written notice (“Notice of Termination for Cause”) of its intention to terminate your employment for Cause, setting forth in reasonable detail the specific conduct constituting Cause and the specific provision(s)
of this Agreement on which it relies. You shall have ten (10) business days after receipt of such written notice to cure such failure (to the extent then curable); 
 (c) Termination by ATLS without Cause upon forty-five (45) days’ prior written notice to you; 
 (d) Termination by ATLS upon your Disability. “Disability” shall mean that you become disabled by reason of physical or mental disability for more than one hundred eighty (180) days
in the aggregate or a period of ninety (90) consecutive days during any 365-day period and the Board of Directors of ATLS determines, in good faith, that you, by reason of such physical or mental disability, are rendered unable to perform your
duties and services hereunder. A termination of your employment by ATLS for Disability shall be communicated to you by written notice, and shall be effective on the thirtieth (30th) day after your receipt of such notice (the “Disability Effective Date”), unless you return to
full-time performance of your duties before the Disability Effective Date; 
 (e) Termination by you for “Good Reason”
upon thirty (30) days’ prior written notice to ATLS. “Good Reason” shall mean: (i) a material reduction in Annual Base Salary, (ii) a demotion of you from the Position, (iii) a material reduction of your
duties under this Agreement; provided that you and ATLS acknowledge that your duties will have been materially reduced if ATLS ceases to be a public company and the Chief Executive Officer of ATLS or Chairman of the board of directors of Atlas
Pipeline Holdings GP, LLC is not, immediately following the transaction pursuant to which ATLS ceases to be a public company, the Chief Executive Officer of ATLS (or the acquiring entity, if any), (iv) ATLS’s requiring you to be relocated
to a location more than 35 miles from your location immediately prior to such relocation, or (v) any action or inaction that constitutes a material breach by ATLS of this Agreement; provided, however, that, other than in the case of a
termination by you for Good Reason pursuant to the proviso clause in clause (iii) of this Section 6(e), a termination by you for Good Reason shall be effective only if such failure has not been cured within ninety (90) days after the
occurrence of the event alleged to constitute Good Reason. A termination of your employment for Good Reason shall, subject to the cure right described in the immediately preceding sentence, be effectuated by you providing ATLS with thirty
(30) days’ prior written notice (“Notice of Termination for Good Reason”) of the termination within two (2) months after the event alleged to constitute Good Reason, setting forth in reasonable detail the specific
conduct of ATLS that constitutes Good Reason and the specific provision(s) of this Agreement on which you rely; 

  
 4 








 (f) Your termination without Good Reason upon sixty (60) days’ prior written
notice to ATLS; and 
 (g) Termination by ATLS at the end of the Initial Employment Term or any Renewal Term by reason of
non-renewal pursuant to the terms and conditions of Section 3. Such a termination shall constitute a termination without Cause for purposes of Sections 5(b) and 7(c)(iv) and otherwise constitute a resignation without Good Reason pursuant to
Section 7(b). 
 (h) The “Date of Termination” means the date of your death, the Disability Effective
Date, the date on which the termination of your employment by ATLS for Cause, by ATLS without Cause, or by you for Good Reason is effective, or the date on which the termination of employment by you without Good Reason is effective in accordance
with this Agreement, as the case may be. 
 7. Consideration Payable to You upon Termination. 

(a) Disability/Death. If your employment is terminated by reason of your Disability or death, ATLS shall pay to you or your
designated beneficiaries (or, if there is no such beneficiary, to your estate or legal representative), as the case may be, in a single lump-sum cash payment within sixty (60) days after the Date of Termination, the sum of the following
amounts: 
 (i) the portion of your Annual Base Salary through the Date of Termination that has been earned and
not yet paid; 
 (ii) an amount in respect of the short-term cash incentive compensation opportunity awarded to
you in respect of the fiscal year in which the Date of Termination occurs equal to the amount of short-term cash incentive compensation earned by you with respect to the prior fiscal year, multiplied by a fraction, the numerator of which is the
number of days in the fiscal year in which the Date of Termination occurs through the Date of Termination, and the denominator of which is the total number of days in the fiscal year in which the Date of Termination occurs; and 

(iii) any earned but unpaid short-term cash incentive compensation for a prior incentive period and, to the extent
required to be paid under the terms of ATLS policy in effect from time to time and applicable law, any accrued but unpaid vacation pay. 
 All other benefits, payments or compensation provided to you hereunder shall terminate. Any restrictions on any APL and/or ATLS options to purchase units or restricted units outstanding and held by you on
the Date of Termination shall terminate as of the Date of Termination, and all such options or units shall be fully vested and exercisable (to the extent applicable) and shall remain in effect and exercisable (to the extent applicable) through the
end of their respective terms, without regard to the termination of your employment. 
 (b) By ATLS for Cause; By You Other
than for Good Reason. If your employment is terminated by ATLS for Cause or if you terminate your employment other than for Good Reason, ATLS shall pay to you your accrued but unpaid Annual Base Salary through


  
 5 








 
the Date of Termination and, to the extent required to be paid under the terms of ATLS policy in effect from time to time and applicable law, any accrued but unpaid vacation pay. All other
benefits, payments or compensation to be provided to you hereunder shall be governed solely by the terms of the applicable plan. 
 (c) By ATLS Other than For Cause or Disability/Death; By You for Good Reason. If ATLS terminates your employment other than for Cause, Death or Disability, or if you terminate employment for Good
Reason, in addition to payment of your accrued but unpaid Annual Base Salary and, to the extent required to be paid under the terms of ATLS policy in effect from time to time and applicable law, any accrued but unpaid vacation pay, in each case
through the Date of Termination, if you sign and deliver to ATLS a customary release of claims against the Company and related parties with respect to all matters arising out of your employment by ATLS or the termination thereof (subject to certain
exceptions set forth in such release) within fifty-three (53) days after the Date of Termination (such release in the form provided by ATLS, the “Release”), and the statutory period within which you may revoke the Release
expires no later than sixty (60) days after the Date of Termination, ATLS shall pay to you: 
 (i) A
pro-rated amount in respect of the short-term cash incentive compensation opportunity awarded to you in respect of the fiscal year in which the Date of Termination occurs based on actual performance for such year. The pro-rata amount will be
calculated as the product of (A) the amount which would have been earned in respect of the award based on actual performance measured at the end of the applicable fiscal year and (B) a fraction, the numerator of which is the number of days
in the fiscal year in which the Date of Termination occurs through the Date of Termination, and the denominator of which is the total number of days in the fiscal year in which the Date of Termination occurs. The pro-rated amount shall be paid in
cash in a lump sum on the date on which you otherwise would have been paid such amount had you remained employed by ATLS; 
 (ii) Monthly severance pay in an amount equal to one-twelfth (1/12) of the sum of your (A) Annual Base Salary and (B) Annual Incentive Compensation (as defined below) for the portion of the
Employment Term (taking into account any applicable Renewal Term pursuant to Section 3) remaining after the Date of Termination, assuming for this purpose that your termination of employment had not occurred (the “Severance
Period”). The severance pay shall be payable in monthly installments during the Severance Period in accordance with ATLS’s regular payroll practices, commencing on the sixtieth (60th) day after the Date of Termination, subject to
the terms and conditions of Section 16(a), if applicable. “Annual Incentive Compensation” shall mean the amount of short-term cash incentive compensation earned by you in respect of the fiscal year prior to the fiscal year in
which the Date of Termination occurs; 
 (iii) For the remainder of the Severance Period, you may elect
continued health coverage under the Company’s health plan in which you participated upon the Date of Termination, as in effect from time to time, provided that you shall be responsible for paying the full monthly cost of such coverage; and
provided further that, if requested in writing by ATLS, you must timely elect continued coverage under Section 4980B(f) of the Internal Revenue Code of 1986, as amended (the “Code” and such coverage, the “COBRA 


  
 6 








 
Coverage”), it being understood in all cases that the COBRA Coverage continuation period under Section 4980B of the Code shall run concurrently with the Severance Period. The
monthly cost shall be the premium determined for purposes of COBRA Coverage under Section 4980B(f)(4) of the Code in effect from time to time (the “COBRA Premium”). Each month in which you pay the COBRA Premium, ATLS shall
reimburse you for the COBRA Premium in an amount equal to the COBRA Premium less the monthly premium charge that is paid by the Company’s active employees for such coverage. As an alternative, where such coverage may not be continued (or where
such continuation would adversely affect the tax status of the plan pursuant to which the coverage is provided or result in penalty taxes to you pursuant to Section 409A of the Code, ATLS may elect to pay you cash in lieu of such coverage in an
amount equal to the product of the number of months then remaining in the Severance Period and the COBRA Premium. 
 (iv) Any restrictions on any APL and/or ATLS options to purchase units or restricted units outstanding and held by you on the Date of Termination shall terminate as of the Date of Termination, and all
such options or units shall be fully vested and exercisable (to the extent applicable) and shall remain in effect and exercisable (to the extent applicable) through the end of their respective terms, without regard to the termination of your
employment. 
 If you do not timely sign and deliver the Release or if you revoke the Release within the statutory period, you
shall forfeit any and all rights to any amounts or benefits provided pursuant to this Section 7(c). The payments and benefits provided pursuant to this Section 7(c) are intended as liquidated damages for a termination of your employment by
ATLS other than for Cause, Death or Disability or for the actions of ATLS leading to a termination of your employment by you for Good Reason, and shall be the sole and exclusive remedy therefor. You shall not be required to mitigate the amount of
any payment provided for in this Section 7(c) by seeking other employment or otherwise, nor shall the amount of any payment or benefit provided for herein be reduced by any compensation or any retirement benefit heretofore or hereafter earned
by you as the result of employment by any other person, firm or corporation. If you become entitled to receive payments provided for in Section 7(c) of this Agreement, you hereby waive your right to receive payments under any severance plan or
similar program of the Company. 
 8. Golden Parachute Excise Tax Modified Cutback. 

(a) Anything in this Agreement to the contrary notwithstanding, in the event Grant Thornton or such other accounting firm as shall be
designated by ATLS (the “Accounting Firm”) shall determine that receipt of all payments or distributions by ATLS or its affiliates in the nature of compensation to you or for your benefit, whether paid or payable pursuant to this
Agreement or otherwise (a “Payment”), would subject you to the excise tax under Section 4999 of the Code, the Accounting Firm shall determine whether to reduce any of the Payments paid or payable pursuant to Section 7(c)
of this Agreement (the “Agreement Payments”) to the “Reduced Amount” (as defined below). The Agreement Payments shall be reduced to the Reduced Amount only if the Accounting Firm determines that you would have a greater
“Net After-Tax Receipt” (as defined below) of aggregate Payments if your Agreement Payments were reduced to the Reduced Amount. If the Accounting Firm determines that you would not have a greater Net


  
 7 








 
After-Tax Receipt of aggregate Payments if your Agreement Payments were so reduced, you shall receive all Agreement Payments to which you are entitled under this Agreement. 

(b) If the Accounting Firm determines that aggregate Agreement Payments should be reduced to the Reduced Amount, ATLS shall promptly give
you notice to that effect and a copy of the detailed calculation thereof. All determinations made by the Accounting Firm under this Section 8 shall be binding upon ATLS and you absent manifest error and shall be made as soon as reasonably
practicable and in no event later than fifteen (15) days following the applicable Date of Termination. For purposes of reducing the Agreement Payments to the Reduced Amount, only amounts payable under this Agreement (and no other Payments)
shall be reduced. All fees and expenses of the Accounting Firm shall be borne solely by ATLS. 
 (c) 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 hereunder, it is possible that amounts will have been paid or distributed by ATLS to or for the benefit of you pursuant
to this Agreement which should not have been so paid or distributed (“Overpayment”) or that additional amounts which will have not been paid or distributed by ATLS to or for the benefit of you pursuant to this Agreement could have
been so paid or distributed (“Underpayment”), in each case, consistent with the calculation of the Reduced Amount hereunder. In the event that the Accounting Firm, based upon the assertion of a deficiency by the Internal Revenue
Service against either ATLS or you which the Accounting Firm believes has a high probability of success determines that an Overpayment has been made, you shall pay any such Overpayment to ATLS together with interest at the applicable federal rate
provided for in Section 7872(f)(2) of the Code; provided, however, that no amount shall be payable by you to the Company if and to the extent such payment would not either reduce the amount on which you are subject to tax under
Section 1 and Section 4999 of the Code or generate a refund of such taxes. In the event that the Accounting Firm, based upon controlling precedent or substantial authority, determines that an Underpayment has occurred, any such
Underpayment shall be paid promptly (and in no event later than 60 days following the date on which the Underpayment is determined) by ATLS to or for the benefit of you together with interest at the applicable federal rate provided for in
Section 7872(f)(2) of the Code. 
 (d) For purposes hereof, (i) “Reduced Amount” shall mean the
greatest amount of Agreement Payments that can be paid that would not result in the imposition of the excise tax under Section 4999 of the Code if the Accounting Firm determines to reduce Agreement Payments pursuant to Section 8(a), and
(ii) “Net After-Tax Receipt” shall mean the present value (as determined in accordance with Sections 280G(b)(2)(A)(ii) and 280G(d)(4) of the Code) of a Payment net of all taxes imposed on you with respect thereto under Sections
1 and 4999 of the Code and under applicable state and local laws, determined by applying the highest marginal rate under Section 1 of the Code and under state and local laws which applied to your taxable income for the immediately preceding
taxable year, or such other rate(s) as the Accounting Firm determined to be likely to apply to you in the relevant tax year(s). 

(e) To the extent requested by you, ATLS shall cooperate with you in good faith in valuing, and the Accounting Firm shall take into
account the value of, services provided or to be provided by you (including without limitation, your agreeing to refrain from performing services pursuant to a covenant not to compete or similar covenant) before, on or after the date of


  
 8 








 
a change in ownership or control of ATLS (within the meaning of Q&A-2(b) of the final regulations under Section 280G of the Code), such that payments in respect of such services may be
considered reasonable compensation within the meaning of Q&A-9 and Q&A-40 to Q&A-44 of the final regulations under Section 280G of the Code and/or exempt from the definition of the term “parachute payment” within the
meaning of Q&A-2(a) of the final regulations under Section 280G of the Code in accordance with Q&A-5(a) of the final regulations under Section 280G of the Code. 

9. Survivorship. The respective rights and obligations of the parties under this Agreement shall survive any termination of
your employment to the extent necessary to the intended preservation of such rights and obligations. 
 10.

 11. Contents of Agreement; Amendment and Assignment. 

(a) This Agreement sets forth the entire understanding between the parties with respect to the subject matter hereof and cannot be
changed, modified, extended or terminated except upon written amendment approved by the Board of ATLS and executed on its behalf by a duly authorized officer and by you. 
 (b) All of the terms and provisions of this Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective heirs, executors, administrators, legal representatives,
successors and assigns of the parties hereto, except that your duties and responsibilities under this Agreement are of a personal nature and shall not be assignable or delegatable in whole or in part by you. 

12. Severability. If any provision of this Agreement or application thereof to anyone or under any circumstances is
adjudicated to be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect any other provision or application of this Agreement which can be given effect without the invalid or unenforceable provision or
application and shall not invalidate or render unenforceable such provision or application in any 

  
 9 








 
other jurisdiction. If any provision is held void, invalid or unenforceable with respect to particular circumstances, it shall nevertheless remain in full force and effect in all other
circumstances. 
 13. Remedies Cumulative; No Waiver. No remedy conferred upon a party by this Agreement is
intended to be exclusive of any other remedy, and each and every such remedy shall be cumulative and shall be in addition to any other remedy given under this Agreement or now or hereafter existing at law or in equity. No delay or omission by a
party in exercising any right, remedy or power under this Agreement or existing at law or in equity shall be construed as a waiver thereof, and any such right, remedy or power may be exercised by such party from time to time and as often as may be
deemed expedient or necessary by such party in its sole discretion. 
 14. Withholding. All payments under this
Agreement shall be made subject to applicable tax withholding, and the Company shall withhold from any payments under this Agreement all federal, state and local taxes as the Company is required to withhold pursuant to any law or governmental rule
or regulation. Except as specifically provided otherwise in this Agreement, you shall bear all expense of, and be solely responsible for, all federal, state and local taxes due with respect to any payment received under this Agreement. 

15. Governing Law. This Agreement shall be governed by and interpreted under the laws of the State of Delaware without
giving effect to any conflict of laws provisions. 
 16. Section 409A. 

(a) Notwithstanding anything in this Agreement to the contrary, if you are a “specified employee” (as defined under
Section 409A of the Code), payment of any amount under this Agreement shall, to the extent necessary in order to avoid the imposition of a penalty or other tax on you under Section 409A of the Code, be delayed for a period of six
(6) months after your “separation from service” (within the meaning of Section 409A of the Code), and the accumulated postponed amount shall be paid in a lump-sum payment within ten (10) days after the end of the six
(6)-month period. If you die during the six (6)-month postponement period prior to the payment of such postponed amount, the amounts withheld on account of Section 409A of the Code shall be paid to the personal representative of your estate
within sixty (60) days after the date of your death. 
 (b) This Agreement is intended to comply with the requirements of
Section 409A of the Code or an exemption thereto and shall in all respects be administered in accordance with Section 409A of the Code or an exemption thereto. Notwithstanding anything in the Agreement to the contrary, distributions may,
to the extent necessary in order to avoid the imposition of a penalty or other tax on you under Section 409A of the Code, only be made under the Agreement upon an event and in a manner permitted by Section 409A of the Code or an applicable
exemption. All payments to be made upon a termination of employment under this Agreement may, to the extent necessary in order to avoid the imposition of a penalty or other tax on you under Section 409A of the Code, only be made upon a
“separation from service” (within the meaning of Section 409A of the Code). For purposes of Section 409A of the Code, the right to a series of payments under this Agreement shall be treated as a right to a series of separate


  
 10 









 
payments. In no event may you, directly or indirectly, designate the calendar year of any payment under this Agreement. All reimbursements and in-kind benefits provided under this Agreement shall
be made or provided in accordance with the requirements of Section 409A of the Code, including, where applicable, the requirement that (i) any reimbursement shall be for expenses incurred during your lifetime (or during a shorter period of
time specified in this Agreement), (ii) the amount of expenses eligible for reimbursement, or in-kind benefits provided, during a calendar year may not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any
other calendar year, (iii) the reimbursement of an eligible expense will be made on or before the last day of the calendar year following the year in which the expense is incurred, and (iv) the right to reimbursement or in-kind benefits is
not subject to liquidation or exchange for another benefit.
