	1.	Purpose 

 The purpose of the Atlas Energy Group, LLC Annual Incentive Plan for Senior
Executives (the “Plan”) is to enhance the ability of Atlas Energy Group, LLC, a Delaware limited liability company (the “Company”), to attract, reward, and retain senior executive employees, to strengthen employee
commitment to the success of the Company, and to align employee interests with those of the unit holders by providing variable compensation, based on the achievement of performance objectives. To this end, the Plan provides a means of annually
rewarding participants based on the performance of the Company and its business units and, where appropriate, on a Participant’s (as defined below) personal performance. 
  

	2.	Definitions 

 “Award” shall mean an incentive award earned by a
Participant under the Plan for any Performance Period. 
 “Board” shall mean the Board of Directors of the Company. 

“Change in Control” means the occurrence of any of the following: 

(a) a merger, consolidation, share exchange, division, or other reorganization or transaction of the Company with any entity, other than such
a transaction that would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) at least 60%
of the combined voting power immediately after such transaction of the surviving entity’s outstanding securities or, in the case of a division, the outstanding securities of each entity resulting from the division; 

(b) the equity holders of the Company approve a plan of complete liquidation or winding-up of the Company; 

(c) a sale or disposition (in one transaction or a series of transactions) of all or substantially all of the assets of the Company; 

(d) during any period of 24 consecutive months, individuals who at the beginning of such period constituted the Board (including for this
purpose any new director whose election or nomination for election or appointment was approved by a vote of at least 2/3 of the directors then still in office who were directors at the beginning of such period) cease for any reason to constitute at
least a majority of the Board; or 
 (e) any other sale of assets or restructuring transaction that has the effect of the enumerated
transactions or events described in any of clauses (a) through (d) above. 

 Notwithstanding the foregoing, with respect to any Award that is subject to Section 409A of
the Code, Change in Control shall mean a “change of control event,” as defined in the regulations and guidance issued under Section 409A of the Code. In addition, notwithstanding the foregoing, the Committee may specify a more limited

 “Code” shall mean the
Internal Revenue Code of 1986, as amended or any successor statute thereto. 
 “Committee” shall mean the Compensation
Committee of the Board.

designated by the Committee to participate in the Plan. 
 “Performance Goals” shall mean performance objectives
established by the Committee for each Performance Period for the purpose of determining the extent to which a Participant will receive an Award for such Performance Period. The Committee may consider factors including, but not limited to,
performance relative to an appropriate group designated by the Committee, total market return and distribution paid to unitholders and factors related to the operation of the business including growth of reserves, growth in production, processing
and intake of natural gas, health and safety performance, environmental compliance, and risk management. The aforementioned performance criteria may be considered either individually or in any combination, applied to the Company as a whole, to a
subsidiary, to a business unit of the Company or any subsidiary, to an affiliate of the Company or any subsidiary, or to any individual, measured either annually or cumulatively over a period of time. To the extent applicable, the Committee, in
determining whether and to what extent a Performance Goal has been achieved, shall use the information set forth in the Company’s audited financial statements and other objectively determinable information. The Performance Goals established by
the Committee may be (but need not be) different each Performance Period, and different Performance Goals may be applicable to different Participants. 

“Performance Period” shall mean the fiscal year of the Company or any other period of up to 12 months designated by the
Committee with respect to which an Award may be earned. 
 “Plan” shall have the meaning set forth in Section 1. 

“Target Award” shall mean the target amount that a Participant will earn as an Award for a Performance Period if the target
level of performance is achieved for each of the Performance Goals set by the Committee for the Participant. A Participant’s Target Award shall be determined by the Committee based on the Participant’s responsibility level, position, or
such other criteria as the Committee shall determine. 
  

	3.	Eligibility 

 All senior executive employees of the Company and its subsidiaries are
eligible to participate in the Plan. The Committee shall designate which senior executive employees shall participate in the Plan for each Performance Period. In order to be eligible to receive an Award with respect to any Performance Period, an

	4.	Administration 

 (a) Committee Authority. The Plan shall be administered by the
Committee. The Committee shall have full discretionary authority to establish the rules and regulations relating to the Plan, to interpret the Plan and those rules and regulations, to select Participants in the Plan, to determine each
Participant’s Target Award and Award amount, to approve all Awards, to decide the facts in any case arising under the Plan and to make all other determinations, including factual determinations, and to take all other actions necessary or
appropriate for the proper administration of the Plan, including the delegation of such authority or power, where appropriate. All powers of the Committee shall be executed in its sole discretion, in the best interest of the Company, not as a
fiduciary, and in keeping with the objectives of the Plan, and need not be uniform as to similarly situated individuals. 
 (b) Committee
Determinations. All Awards shall be made conditional upon the Participant’s acknowledgement, in writing or by acceptance of the Award, that all decisions and determinations of the Committee shall be final, conclusive, and binding on the
Participant, his or her beneficiaries, and any other person having or claiming an interest under such Award. Awards need not be uniform as among Participants. The Committee’s administration of the Plan, including all such rules and regulations,
interpretations, selections, determinations, approvals, decisions, delegations, amendments, terminations, and other actions, shall be final, conclusive, and binding on the Company and all employees of the Company, including the Participants and
their respective beneficiaries. 
  

	5.	Determination of Awards 

 (a) Target Awards and Performance Goals. As soon as
practicable following the beginning of the Performance Period, the Committee shall determine the senior executive employees who shall be Participants during that Performance Period, each Participant’s Target Award, and the Performance Goals for
each Participant, all of which shall be set forth in the Committee’s minutes. The Performance Goals may provide for differing amounts to be paid based on differing thresholds of performance. The Committee shall specify in the minutes how the
financial calculations for the Performance Goals will be made, including what, if any, adjustments shall be made in the event of a change in capitalization, extraordinary event, change in applicable accounting rules or principles, or other event.
The Committee shall establish a target dollar amount that may be paid to a Participant for the Performance Period. The Company shall notify each Participant of the applicable Performance Goals and other terms of Awards for the Performance Period.

 (b) Earning an Award. A Participant will earn an Award for a Performance Period based on the level of achievement of the
Performance Goals established by the Committee for that period; provided that the Committee may reduce or increase an Award for any Performance Period based on its assessment of personal performance or other factors. 

  
 3 

	6.	Payment of Awards 

 The Committee shall certify and announce the Awards that will be paid
by the Company to each Participant as soon as practicable following the final determination of the Company’s financial results for the relevant Performance Period. Subject to the provisions of Section 7, payment of the Awards certified by
the Committee shall be made as soon as practicable following the close of the Performance Period, but in any event within 2.5 months after the close of the Performance Period and as otherwise consistent with the requirements of
Section 409A of the Code. Awards shall be paid in cash, in equity, or in a combination thereof. Any common or phantom units may be issued under a long-term incentive plan of the Company or of its subsidiaries. 

 

	7.	Limitations on Rights to Payment of Awards 

 (a) Employment. No Participant shall
have any right to receive payment of an Award under the Plan for a Performance Period unless the Participant remains in the employ of the Company through the last day of the Performance Period; provided, however, that the Committee may
determine that if a Participant’s employment with the Company terminates prior to the end of the Performance Period, the Participant shall remain eligible to receive a prorated portion of any Award that would otherwise have been earned for the
Performance Period, in such circumstances as the Committee deems appropriate. If payments are to be made under the Plan after a Participant’s death, such payments shall be made to the personal representative of the Participant’s estate.

 (b) Leaves of Absence. If a Participant is on an authorized leave of absence during the Performance Period, the Participant may be
eligible to receive a prorated portion of any Award that would otherwise have been earned, as determined by the Committee. 
  

	8.	Change in Control 

 Unless the Committee determines otherwise, if a Change in Control
occurs prior to the end of a Performance Period, (a) each Participant shall receive an Award for the Performance Period in which the Change in Control occurs, based on performance measured as of the date of the Change in Control, or as
otherwise determined by the Committee, and subject to such adjustment as the Committee deems appropriate, (b) the Performance Period shall end as of the date of the Change in Control, and (c) Awards shall be paid within 60 days after
the Change in Control (regardless of whether the Participant remains employed after the Change in Control). 
  

	9.	Deferrals 

 Notwithstanding Section 6, the Committee may permit a Participant to
defer receipt of an Award that would otherwise be payable to the Participant. The Committee shall establish rules and procedures for any such deferrals, consistent with the applicable requirements of Section 409A of the Code. 

  
 4 

	10.	Amendments 

 The Committee may at any time amend the Plan. No amendment that adversely
affects any Participant’s rights to an Award that has been earned prior to the date of the amendment shall be effective unless the Participant consents to the amendment. 
  

	11.	Termination 

 The Committee may terminate the Plan at any time. In the case of
termination of the Plan, each Participant may receive all or a portion of the Award that would otherwise have been earned for the then-current Performance Period had the Plan not been terminated, as determined by the Committee. Each Award shall be
paid as soon as practicable, but in no event later than 2.5 months after the Performance Period in which the Plan terminates. 
  

	12.	Miscellaneous Provisions 

 (a) No Employment Right. The Plan is not a contract
between the Company and any employee or Participant. Neither the establishment of the Plan, nor any action taken hereunder, shall be construed as giving any employee or any Participant any right to be retained in the employ of the Company. The
Company is under no obligation to continue the Plan. Nothing contained in the Plan shall limit or affect in any manner or degree the normal and usual powers of management, exercised by the officers and the Board or committees thereof, to change the
duties or the character of employment of any employee or to remove any individual from the employment of the Company at any time and for any reason, all of which rights and powers are expressly reserved. 

(b) No Assignment. A Participant’s right and interest under the Plan may not be assigned or transferred, except upon death as
provided in Section 7 of the Plan, and any attempted assignment or transfer shall be null and void. 
 (c) No Funding of the Plan;
Limitation on Rights. The Plan shall be unfunded. The Company shall not be required to establish any special or separate fund or to make any other segregation of assets to assure the payment of any Awards under the Plan. Nothing contained in the
Plan and no action taken pursuant hereto shall create or be construed to create a fiduciary relationship between the Company and any Participant or any other person. No Participant or any other person shall under any circumstances acquire any
property interest in any specific assets of the Company. To the extent that any person acquires a right to receive payment from the Company hereunder, such right shall be no greater than the right of any unsecured general creditor of the Company.

 (d) Obligations to the Company. If a Participant becomes entitled to payment of an Award under the Plan, and if at such time the
Participant has outstanding any debt, obligation, or other liability representing an amount owing to the Company, then the Company may offset such amount owed to it against the Award otherwise distributable. Any determination under this
Section 12(d) shall be made by the Committee in its sole discretion. 

  
 5 

 (e) Withholding Taxes. All Awards under the Plan shall be subject to applicable federal
(including FICA), state, and local tax withholding requirements. The Company may require that the Participant or his or her personal representative pay to the Company the amount of any federal, state, or local taxes that the Company is required to
withhold with respect to such Awards, or the Company may deduct from other wages paid by the Company the amount of any withholding taxes due with respect to such Awards. 

(f) Compliance with Law. It is the intent of the Company that the Awards under the Plan qualify for the “short-term deferral”
exception to Section 409A of the Code. To the extent that any legal requirement of Section 409A of the Code as set forth in the Plan ceases to be required under Section 409A of the Code, that Plan provision shall cease to apply. The
Committee may revoke any Award if it is contrary to law or modify an Award to bring it into compliance with any valid and mandatory government regulation. 

(g) Governing Law. The validity, construction, interpretation, and effect of the Plan shall exclusively be governed by and determined
in accordance with the law of Delaware, without giving effect to the conflict of laws provisions thereof. 
 Adopted by the Board of
Directors on February 23, 2015

 ARTICLE III 

REPRESENTATIONS AND WARRANTIES OF ATLAS 

Atlas represents and warrants to each Purchaser as of the Closing as follows: 

Section 3.01 Existence. Each of Atlas and its Subsidiaries: (i) is a corporation, limited partnership, partnership or limited
liability company, as applicable, duly organized, validly existing and in good standing under the Laws of the state or other jurisdiction of its incorporation or organization; (ii) has all requisite power and authority, and has all material
governmental licenses, authorizations, consents and approvals, necessary to own, lease, use and operate its Properties and carry on its business as currently conducted and as such business is described in the Atlas SEC Documents, except where the
failure to obtain such licenses, authorizations, consents and approvals would not reasonably be expected to have a material adverse effect on Atlas. Each of Atlas and its Subsidiaries is duly qualified or licensed and in good standing as a foreign
limited liability company, limited partnership, partnership or corporation, as applicable, and is authorized to do business in each jurisdiction in which the ownership or leasing of its respective Properties or the character of its respective
operations makes such qualification necessary, except where the failure to obtain such qualification, license, authorization or good standing would not reasonably be expected to have a material adverse effect on Atlas. 

Section 3.02 Capitalization and Valid Issuance of Purchased Units. 

(a) As of February 23, 2015 (the “Capitalization Date”), there are 52,021,532 common units of ATLS issued and
outstanding. Assuming that the record date for the Distribution were the Capitalization Date, immediately following the Distribution and prior to the issuance and sale of the Purchased Units, the issued and outstanding limited liability company
interests of Atlas would consist of 26,010,766 Common Units. All of the Common Units outstanding at Closing have been duly authorized and validly issued in accordance with applicable Law and the LLC Agreement and are fully paid (to the extent
required under the LLC Agreement) and non-assessable (except as such non-assessability may be affected by Section 18-607 or 18-804 of the Delaware Act). 

(b) Other than the Atlas 2015 Long-Term Incentive Plan described in the Atlas SEC Reports, Atlas has no equity compensation plans that
contemplate the issuance of Common Units (or securities convertible into or exchangeable for Common Units). Atlas has no outstanding indebtedness having the right to vote (or convertible into or exchangeable for securities having the right to vote)
on any matters on which the holders of Common Units may vote. Except as set forth in the first sentence of this Section 3.02(b), as contemplated by this Agreement, as are contained in the LLC Agreement, as amended by Amendment 1, or as
described in the Atlas SEC Documents, there are no outstanding or authorized (i) options, warrants, preemptive rights, subscriptions, calls or other rights, convertible securities, agreements, claims or commitments of any character obligating
Atlas or any of its Subsidiaries to issue, transfer or sell any limited liability company interests or other equity interests in Atlas or any of its Subsidiaries or securities convertible into or exchangeable for such limited liability company
interests or other equity interests, (ii) obligations of Atlas or any of its Subsidiaries to repurchase, redeem or otherwise acquire any limited liability company interests or other equity interests in Atlas or any of its Subsidiaries or any
such securities or agreements listed in clause 

  
 6 

 
(i) of this sentence or (iii) voting trusts or similar agreements to which Atlas or any of its Subsidiaries is a party with respect to the voting of the equity interests of Atlas or any of
its Subsidiaries. 
 (c) Except as described in the Atlas SEC Documents, all of the issued and outstanding equity interests of each of
Atlas’s Subsidiaries are owned, directly or indirectly, by Atlas free and clear of any Liens (except for such restrictions as may exist under applicable Law and except for such Liens as may be imposed under the Atlas Financing Arrangements),
and all such ownership interests have been duly authorized and validly issued and are fully paid (to the extent required by applicable Law and the organizational documents of Atlas’s Subsidiaries, as applicable) and non-assessable (except as
non-assessability may be affected by Section 18-607 or 18-804 of the Delaware Act, similar statutes or the organizational documents of Atlas’s Subsidiaries, as applicable) and free of preemptive rights, with no personal liability attaching
to the ownership thereof. 
 (d) The offer and sale of the Purchased Units and the limited liability company interests represented thereby,
and the Common Units issuable upon conversion of the Purchased Units in accordance with the terms of the Series A Units as reflected in Amendment 1, are duly authorized by Atlas pursuant to the LLC Agreement, as amended by Amendment 1, and, when
issued and delivered to the Purchaser against payment therefor in accordance with the terms of this Agreement, will be validly issued, fully paid (to the extent required by applicable Law and the LLC Agreement, as amended by Amendment 1) and
non-assessable (except as such non-assessability may be affected by Section 18-607 or 18-804 of the Delaware Act) and will be free of any and all Liens and restrictions on transfer, other than restrictions on transfer under the LLC Agreement,
as amended by Amendment 1, the Registration Rights Agreement and applicable state and federal securities Laws and other than such Liens as are created by the Purchaser thereof. 

(e) Atlas’s Common Units are approved for listing on The New York Stock Exchange and Atlas has not received any notice of delisting. 

(f) The Purchased Units shall have those rights, preferences, privileges and restrictions governing the Series A Units as set forth in the LLC
Agreement, as amended by Amendment 1. 
 Section 3.03 Atlas SEC Documents. Atlas has filed with the Commission all forms,
registration statements, reports, schedules and statements required to be filed by it under the Exchange Act or the Securities Act (all such documents filed on or prior to the date of this Agreement, including the Form 10 Registration Statement,
collectively, the “Atlas SEC Documents”). The Atlas SEC Documents, including any audited or unaudited financial statements and any notes thereto or schedules included therein (the “Atlas Financial Statements”), at
the time filed (in the case of registration statements and the Form 10 Registration Statement, solely on the dates of effectiveness) (except to the extent corrected by a subsequently filed Atlas SEC Document filed prior to the Closing) (i) did
not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading,
(ii) complied in all material respects with the applicable 

  
 7 

 
requirements of the Exchange Act and the Securities Act, as the case may be, (iii) complied as to form in all material respects with applicable accounting requirements and with the published
rules and regulations of the Commission with respect thereto, (iv) were prepared in accordance with GAAP applied on a consistent basis during the periods involved (except as may be indicated in the notes thereto or, in the case of unaudited
statements, as permitted by the Commission) and (v) fairly presented (subject in the case of unaudited statements to normal, recurring and year-end audit adjustments) in all material respects the consolidated financial position and status of
the business of Atlas as of the dates thereof and the consolidated results of its operations and cash flows for the periods then ended. Grant Thornton LLP is an independent registered public accounting firm with respect to Atlas and has not resigned
or been dismissed as independent registered public accountants of Atlas as a result of or in connection with any disagreement with Atlas on any matter of accounting principles or practices, financial statement disclosure or auditing scope or
procedures. 
 Section 3.04 Litigation. Except as set forth in the Atlas SEC Documents, there is no Action pending or, to the
knowledge of Atlas, threatened in writing against Atlas or any of its Subsidiaries that would reasonably be expected to prevent the consummation of the transactions contemplated by this Agreement. 

Section 3.05 No Breach. The execution, delivery and performance by Atlas of the Basic Documents to which it is a party and all
other agreements and instruments in connection with the transactions contemplated by the Basic Documents, and compliance by Atlas with the terms and provisions hereof and thereof, do not (a) violate any provision of any Law applicable to Atlas
or any of its Subsidiaries or any of their respective Properties, (b) conflict with or result in a violation of any provision of the Certificate of Formation of Atlas, as amended, or the LLC Agreement, as amended by Amendment 1, or any
organizational documents of any of Atlas’s Subsidiaries, (c) require any consent, approval or notice under or result in a violation or breach of or constitute (with or without due notice or lapse of time or both) a default (or give rise to
any right of termination, cancellation or acceleration) under (i) any material note, bond, mortgage, license, or loan or credit agreement to which Atlas or any of its Subsidiaries is a party or by which Atlas or any of its Subsidiaries or any
of their respective Properties may be bound or (ii) any other material agreement, instrument or obligation, or (d) result in or require the creation or imposition of any Lien upon or with respect to any of the Properties now owned or
hereafter acquired by Atlas or any of its Subsidiaries, except in the cases of clauses (a), (c) and (d) where such violation, default, breach, termination, cancellation, failure to receive consent or approval, or acceleration with respect
to the foregoing provisions of this Section 3.05 would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on Atlas. 

Section 3.06 Authority. Atlas has all necessary limited liability company power and authority to execute, deliver and perform its
obligations under the Basic Documents to which it is a party and to consummate the transactions contemplated thereby; the execution, delivery and performance by Atlas of each of the Basic Documents to which it is a party, and the consummation of the
transactions contemplated thereby, have been duly authorized by all necessary action on its part; and the Basic Documents constitute the legal, valid and binding obligations of Atlas, enforceable in accordance with their terms, except as such
enforceability may be limited by bankruptcy, insolvency, fraudulent transfer and similar Laws affecting 

  
 8 

 
creditors’ rights generally or by general principles of equity. Except as contemplated by Amendment 1, no approval by the holders of Common Units is required as a result of Atlas’s
issuance and sale of the Purchased Units. 
 Section 3.07 Compliance with Laws. Neither Atlas nor any of its Subsidiaries is in
violation of any judgment, decree or order or any Law applicable to Atlas or its Subsidiaries, except as would not, individually or in the aggregate, have a material adverse effect on Atlas. Atlas and its Subsidiaries possess all material
certificates, authorizations and permits issued by the appropriate regulatory authorities necessary to conduct their respective businesses, except where the failure to possess such certificates, authorizations or permits would not, individually or
in the aggregate, reasonably be expected to have a material adverse effect on Atlas, and neither Atlas nor any such Subsidiary has received any notice of proceedings relating to the revocation or modification of any such certificate, authorization
or permit, except where such potential revocation or modification would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on Atlas. 

Section 3.08 Approvals. Except as contemplated by this Agreement, or as required by the Commission in connection with Atlas’s
obligations under the Registration Rights Agreement, no authorization, consent, approval, waiver, license, qualification or written exemption from, nor any filing, declaration, qualification or registration with, any Governmental Authority or any
other Person is required in connection with the execution, delivery or performance by Atlas of any of the Basic Documents to which it is a party, except where the failure to receive such authorization, consent, approval, waiver, license,
qualification or written exemption or to make such filing, declaration, qualification or registration would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on Atlas. 

Section 3.09 Investment Company Status. Atlas is not an “investment company” within the meaning of the Investment
Company Act of 1940, as amended. 
 Section 3.10 Offering. Assuming the accuracy of the representations and warranties of the
Purchaser contained in this Agreement, the sale and issuance of the Purchased Units pursuant to this Agreement are exempt from the registration requirements of the Securities Act, and neither Atlas nor any authorized Representative acting on its
behalf has taken or will take any action hereafter that would cause the loss of such exemption. 
 Section 3.11 Certain Fees.
The Purchasers shall not be liable for any fees or commissions payable by Atlas to brokers, finders or investment bankers with respect to the sale of any of the Purchased Securities or the consummation of the transactions contemplated by this
Agreement. Atlas agrees that it will indemnify and hold harmless Purchaser from and against any and all claims, demands or liabilities for broker’s, finder’s, placement or other similar fees or commissions incurred by Atlas or alleged to
have been incurred by Atlas in connection with the sale of Purchased Securities or the consummation of the transactions contemplated by this Agreement. 

Section 3.12 Registration Rights. Neither the execution of this Agreement nor the issuance of the Purchased Units as contemplated
by this Agreement gives rise to any rights for or relating to the registration of any securities of Atlas, other than pursuant to the Registration Rights Agreement.

Each Purchaser hereby represents and warrants to Atlas with respect to itself, as of the Closing, as follows: 

Section 4.01 Valid Existence. Purchaser (i) to the extent not a natural person, is duly organized, validly existing and in
good standing under the Laws of its jurisdiction of formation or organization and (ii) has all requisite power, and has all material governmental licenses, authorizations, consents and approvals, necessary to own its Properties and carry on its
business as its business is now being conducted, except where the failure to obtain such licenses, authorizations, consents and approvals would not have and would not reasonably be expected to have a Purchaser Material Adverse Effect. 

Section 4.02 No Breach. The execution, delivery and performance by Purchaser of the Basic Documents to which it is a party and all
other agreements and instruments in connection with the transactions contemplated by the Basic Documents to which it is a party, and compliance by Purchaser with the terms and provisions hereof and thereof and the purchase of the Purchased Units by
Purchaser do not (a) violate any provision of any Law, governmental permit, determination or award having applicability to Purchaser or any of its Properties, (b) conflict with or result in a violation of any provision of the
organizational documents of Purchaser or (c) require any consent (other than standard internal consents), approval or notice under or result in a violation or breach of or constitute (with or without due notice or lapse of time or both) a
default (or give rise to any right of termination, cancellation or acceleration) under (i) any material note, bond, mortgage, license, or loan or credit agreement to which Purchaser is a party or by which Purchaser or any of its Properties may
be bound or (ii) any other such material agreement, instrument or obligation, except in the case of clauses (a) and (c) where such violation, default, breach, termination, cancellation, failure to receive consent or approval, or
acceleration with respect to the foregoing provisions of this Section 4.02 would not, individually or in the aggregate, reasonably be expected to have a Purchaser Material Adverse Effect. 

Section 4.03 Investment. The Purchased Units are being acquired for Purchaser’s own account, not as a nominee or agent, and
with no present intention of distributing the Purchased Units or any part thereof, and Purchaser has no present intention of selling or granting any participation in or otherwise distributing the same in any transaction in violation of the
securities Laws of the United States of America or any state, without prejudice, however, to Purchaser’s right at all times to sell or otherwise dispose of all or any part of the Purchased Units under a registration statement under the
Securities Act and applicable state securities Laws or under an exemption from such registration available thereunder (including, if available, Rule 144 promulgated thereunder). If Purchaser should in the future decide to dispose of any of the
Purchased Units, Purchaser understands and agrees that it may do so only (a)(i) in compliance with the Securities Act and applicable state securities Law, as then in effect, or pursuant to an exemption therefrom (including Rule 144 under the
Securities Act) or (ii) in the manner 

  
 10 

 
contemplated by any registration statement pursuant to which such securities are being offered, (b) if no stop-transfer instructions will be in effect with respect to such securities and
(c) in compliance with the LLC Agreement, including Amendment 1. 
 Section 4.04 Nature of Purchaser. Purchaser represents

business and financial experience it has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Purchased Securities, is able to
bear the economic risk of such investment and, at the present time, would be able to afford a complete loss of such investment. 

Section 4.05 Restricted Securities. Purchaser understands that the Purchased Securities it is purchasing are characterized as
“restricted securities” under the federal securities Laws inasmuch as they are being acquired from Atlas in a transaction not involving a public offering and that under such Laws and applicable regulations such securities may be resold
without registration under the Securities Act only in certain limited circumstances. In connection with the foregoing, Purchaser represents that it is knowledgeable with respect to Rule 144 of the Commission promulgated under the Securities Act.

 Section 4.06 Certain Fees. No fees or commissions will be payable by Purchaser to brokers, finders or investment bankers with
respect to the sale of any of the Purchased Securities or the consummation of the transactions contemplated by this Agreement. Atlas will not be liable for any such fees or commissions. Purchaser agrees that it will indemnify and hold harmless Atlas
from and against any and all claims, demands or liabilities for broker’s, finder’s, placement or other similar fees or commissions incurred by Purchaser or alleged to have been incurred by Purchaser in connection with the purchase of
Purchased Securities or the consummation of the transactions contemplated by this Agreement. 
 Section 4.07 Legend. The
Purchased Units shall bear the legend set forth in Section 5.9(b)(vi) of Amendment 1 (with appropriate comparable notations or other arrangements being made with respect to any uncertificated units).

with all other materials that it considers relevant to an investment in the Purchased Units, has had a full opportunity to ask questions of and receive answers from Atlas or any person or persons acting on behalf of Atlas concerning the terms and
conditions of an investment in the Purchased Units; (b) has conducted, to the extent it deemed necessary, an independent investigation of such matters as, in its judgment, is necessary for it to make an informed investment decision with respect
to the Purchased Units and Atlas; (c) is not relying upon, and has not relied upon, any statement, representation or warranty made by any person except for the statements, representations and warranties contained in this Agreement and the Atlas
SEC Documents; and (d) has made all decisions in connection with the offer and sale of the Purchased Securities as the result of arm’s-length negotiations.

INDEMNIFICATION, COSTS AND EXPENSES 

Section 7.01 Indemnification by Atlas. Atlas agrees to indemnify Purchaser and its Representatives (collectively,
“Purchaser Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of action, and, in connection therewith,
and promptly upon demand, pay and reimburse each of them for all costs, losses, liabilities, damages or expenses of any kind or nature whatsoever, including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred
in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of or in any way related to (i) any actual or proposed use by
Atlas of the proceeds of the sale of the Purchased Units or (ii) the breach of any of the representations, 

  
 14 

 
warranties or covenants of Atlas contained herein; provided that such claim for indemnification relating to a breach of a representation or warranty is made prior to the expiration of such
representation or warranty. 
 Section 7.02 Indemnification by Purchasers. Each Purchaser agrees, severally but not jointly, to
indemnify Atlas and its Representatives (collectively, “Atlas Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands
and causes of action, and, in connection therewith, and promptly upon demand, pay and reimburse each of them for all costs, losses, liabilities, damages or expenses of any kind or nature whatsoever, including the reasonable fees and disbursements of
counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of or in any
way related to the breach of any of the representations, warranties or covenants of such Purchaser contained herein; provided that such claim for indemnification relating to a breach of a representation or warranty is made prior to the expiration of
such representation or warranty. 
 Section 7.03 Indemnification Procedure. Promptly after any Atlas Related Party or Purchaser
Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action or proceeding by a third party, which the Indemnified Party believes in good faith is
an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action or proceeding, but failure to so
notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall
state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified Party, any such
matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party
shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include, subject to limitations regarding confidential information or
information subject to the attorney-client privilege, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such
cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as
the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided,
however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has failed to
assume the defense or employ counsel reasonably acceptable to the Indemnified Party or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have
concluded that there may be reasonable defenses 

  
 15 

 
available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to
conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and
fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred; provided that the Indemnifying Party shall not have the obligation to reimburse fees and expenses for more than
one counsel for all Indemnified Parties (in addition to one local counsel for each applicable jurisdiction). Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of
the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, involves no admission of wrongdoing or malfeasance by, and includes a complete release from liability of, the Indemnified Party. 

Section 7.04 Limitations on Indemnification. An Indemnifying Party shall not have any liability for indemnification under
Section 7.01(ii) or 7.02 (other than for breaches of Sections 3.01, 3.02, 3.06, 3.11, Section 4.01 or 4.06) unless and until the aggregate amount that is indemnifiable by such Indemnifying Party under such respective section exceeds
(i) in the case of an Atlas Related Party, 1% of the aggregate Commitment Amount, in which case the Atlas Related Party shall be responsible for the excess up to a cap of 15% of such aggregate Commitment Amount or (ii) in the case of a
Purchaser (including its Purchaser Related Parties) 1% of such Purchaser’s Commitment Amount, in which case the Purchaser (including its Purchaser Related Parties) shall be responsible for the excess up to a cap of 15% of such Commitment
Amount. Notwithstanding the foregoing, in no event shall a Purchaser (including its Purchaser Related Parties) be liable to indemnify the Atlas Related Parties for, or entitled to receive indemnification payments, in an aggregate amount exceeding
its Commitment Amount. An Indemnifying Party shall not be liable for any punitive or consequential damages, except to the extent such damages are actually paid to third parties in connection with a third party claim.

Basic Documents, and the remaining provisions shall remain in full force and effect. The Basic Documents have been reviewed and negotiated by sophisticated parties with access to legal counsel and shall not be construed against the drafter.

 Section 8.02 Survival of Provisions. The representations and warranties set forth in
this Agreement shall survive the execution and delivery of this Agreement and the issuance and delivery of the Purchased Units for a period of one year, with the exception that representations and warranties set forth in Sections 3.01, 3.02, 3.06,
3.11 and Section 4.01 and 4.06 shall survive perpetually. The covenants made in this Agreement or any other Basic Document shall survive the Closing of the transactions described herein and remain operative and in full force and effect
regardless of acceptance of any of the Purchased Units and payment therefor and repayment, conversion, exercise or repurchase thereof. All indemnification obligations of Atlas and the Purchaser pursuant to Section 3.11, Section 4.06 and
Article VII of this Agreement shall remain operative and in full force and effect unless such obligations are expressly terminated in a writing by the Parties referencing the particular Article or Section, regardless of any purported general
termination of this Agreement and following the Closing, shall provide the sole and exclusive remedy for any and all claims under this Agreement. 

Section 8.03 No Waiver; Modifications in Writing. 

(a) Delay. No failure or delay on the part of any Party in exercising any right, power or remedy hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any right, power or remedy. The remedies provided for herein are cumulative and are not exclusive
of any remedies that may be available to a Party at law or in equity or otherwise. 
 (b) Specific Waiver. Except as otherwise
provided in this Agreement or the Registration Rights Agreement, no amendment, waiver, consent, modification or termination of any provision of this Agreement or any other Basic Document shall be effective unless signed by each of the Parties or
each of the original signatories thereto affected by such amendment, waiver, consent, modification or termination. Any amendment, supplement or modification of or to any provision of this Agreement or any other Basic Document, any waiver of any
provision of this Agreement or any other Basic Document and any consent to any departure by Atlas from the terms of any provision of this Agreement or any other Basic Document shall be effective only in the specific instance and for the specific
purpose for which made or given. Except where notice is specifically required by this Agreement, no notice to or demand on any Party in any case shall entitle any Party to any other or further notice or demand in similar or other circumstances. 

Section 8.04 Binding Effect; Assignment. 

(a) Binding Effect. This Agreement shall be binding upon Atlas, Purchaser, and their respective successors and permitted assigns. Except
as expressly provided in this Agreement, this Agreement shall not be construed so as to confer any right or benefit upon any Person other than the Parties to this Agreement and as provided in Article VII, and their respective successors and
permitted assigns. 
 (b) Assignment of Purchased Units and Warrants. All or any portion of a Purchaser’s Purchased Units
purchased pursuant to this Agreement may be sold, assigned or pledged by Purchaser, subject to compliance with applicable securities Laws. 

  
 17 

 (c) Assignment of Rights. Purchaser may assign all or any portion of its rights, subject
to an express assumption of each of the obligations under this Agreement, without the consent of Atlas to any Affiliate of Purchaser, and in each case the assignee shall be deemed to be a Purchaser hereunder with respect to such assigned rights or
obligations and shall agree to be bound by the provisions of this Agreement. Except as expressly permitted by this Section 8.04(c), such rights and obligations may not otherwise be transferred except with the prior written consent of Atlas, in which
case the assignee shall be deemed to be a Purchaser hereunder with respect to such assigned rights or obligations and shall agree to be bound by the provisions of this Agreement. Schedule 2.01 shall be revised to reflect the actual Purchaser(s) and
allocations at the Closing. 
 Section 8.05 Aggregation of Purchased Units. All Purchased Units held or acquired by Persons who
are Affiliates of one another shall be aggregated together for the purpose of determining the availability of any rights under this Agreement. 

Section 8.06 Communications. All notices and demands provided for hereunder shall be in writing and shall be given by regular
mail, registered or certified mail, return receipt requested, facsimile, air courier guaranteeing overnight delivery, electronic mail or personal delivery to the following addresses set forth on the signature pages hereof or to such other address as
Atlas or Purchasers may designate in writing. All notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; upon actual receipt if sent by registered or certified mail, return receipt
requested, or regular mail, if mailed; when receipt acknowledged, if sent via facsimile; and upon actual receipt when delivered to an air courier guaranteeing overnight delivery or via electronic mail. 

Section 8.07 Entire Agreement. This Agreement and the other Basic Documents are intended by the Parties as a final expression of
their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the Parties hereto and thereto in respect of the subject matter contained herein and therein. There are no restrictions, promises, warranties
or undertakings, other than those set forth or referred to herein or therein with respect to the rights granted by Atlas or a Purchaser set forth herein or therein. This Agreement and the other Basic Documents supersede all prior agreements and
understandings between the Parties with respect to such subject matter. 
 Section 8.08 Governing Law; Submission to
Jurisdiction. This Agreement, and all claims or causes of action (whether in contract or tort) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim
or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement), will be construed in accordance with and governed by the Laws of the State of Delaware without regard to
principles of conflicts of laws. Any action against any party relating to the foregoing shall be brought in any federal or state court of competent jurisdiction located within the State of Delaware, and the parties hereto hereby irrevocably submit
to the non-exclusive jurisdiction of any federal or state court located within the State of Delaware over any such action. The parties hereby irrevocably waive, to the fullest extent permitted by applicable Law, any objection which they may now or
hereafter have to the laying of venue of any such dispute brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each of the parties hereto agrees that a judgment in any such dispute may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by Law. 

  
 18 

 Section 8.09 Execution in Counterparts. This Agreement may be executed in any number
of counterparts and by different Parties hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the
same Agreement. 
 Section 8.10 Termination. 

(a) Notwithstanding anything herein to the contrary, this Agreement may be terminated on or any time prior to the Closing by Purchasers or by
Atlas, in each case, (A) upon a breach of any representation or warranty of any other Party set forth in this Agreement, (B) upon a breach in any material respect of any covenant or agreement on the part of any other Party set forth in
this Agreement (either (A) or (B) above being a “Terminating Breach”) if such Terminating Breach would cause the satisfaction of the conditions to the terminating Party’s obligations to be impossible and such
Terminating Breach is not cured within 20 Business Days after written notice from the terminating Party or (C) if the Closing does not occur on or before June 30, 2015; provided, that such failure of the Closing to occur is not due,
in whole or in part, to the failure of such Party to perform and comply in all material respects with the covenants and agreements to be performed or complied with by such Party prior to the Closing. 

(b) Notwithstanding anything herein to the contrary, this Agreement shall automatically terminate on or any time prior to the Closing: 

(i) if the ATLS Merger Agreement is terminated; or 

(ii) if a Law shall have been enacted or promulgated, or if any Action shall have been taken by any Governmental Authority of competent
jurisdiction which permanently restrains, precludes, enjoins or otherwise prohibits the consummation of the transactions contemplated by this Agreement or makes the transactions contemplated by this Agreement illegal. 

(c) In the event of the termination of this Agreement as provided in Section 8.10(a) or Section 8.10(b), this Agreement shall
forthwith become null and void. In the event of such termination, there shall be no liability on the part of any Party hereto, except as set forth in Article VII of this Agreement and except with respect to the requirement to comply with any
confidentiality agreement in favor of Atlas; provided that nothing herein shall relieve any Party from any liability or obligation with respect to any willful breach of this Agreement. 

Section 8.11 Obligations Limited to Parties to Agreement. Each of the parties hereto covenants, agrees and acknowledges that no
Person other than the Purchasers (and their permitted assignees) and Atlas shall have any obligation hereunder and that, notwithstanding that one or more of the Purchasers and their permitted assignees may be a corporation, limited partnership,
partnership or limited liability company, no recourse under this Agreement or the other Basic Documents or under any documents or instruments delivered in connection herewith or therewith shall be had against any former, current or future director,
officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of the Purchasers or Atlas 

  
 19 

 
or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, whether by the enforcement of
any assessment or by any legal or equitable proceeding, or by virtue of any applicable Law, it being expressly agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise be incurred by any former,
current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of the Purchasers or Atlas or any former, current or future director, officer, employee, agent, general or limited partner,
manager, member, stockholder or Affiliate of any of the foregoing, as such, for any obligations of the Purchasers and Atlas under this Agreement or the other Basic Documents or any documents or instruments delivered in connection herewith or
therewith or for any claim based on, in respect of or by reason of such obligation or its creation.
