Section 2.3(a) hereof, unless the Expiry Date is determined to be an earlier date as follows: 
  

	 	(a)	Death - The Expiry Date of a Stock Option held by a Participant that had vested immediately prior to his or her death will be the earlier of the expiry date
shown on the relevant Notice of Grant and the date that is one hundred and eighty (180) days after the date of his or her death. Stock Options that are outstanding but unvested immediately prior to a Participant’s death will immediately
terminate and become null, void and of no effect upon the death of the Participant. If a Participant dies, the legal representatives of the Participant may exercise such of the Participant’s Stock Options that, by their terms, were exercisable
on the date of death, prior to the Expiry Date. 

  
 - 6 -

	 	(b)	Disability – In the event of the Disability of a Participant, the Board may in its discretion determine that such Participant shall no longer be an Eligible
Person. In the event a Participant ceases to be an Eligible Person as a result of Disability, then the Expiry Date of a Stock Option that had vested on the date such Participant ceases to be an Eligible Person will be the earlier of the expiry date
shown on the relevant Notice of Grant and the date one hundred and eighty (180) days following the date such Participant ceases to be an Eligible Person. Stock Options that are outstanding but unvested on the date such Participant ceases to be an
Eligible Person will immediately terminate and become null, void and of no effect. 

  

	 	(c)	Retirement – In the event a Participant ceases to be an Eligible Person as a result of his or retirement in accordance with the Company’s then
applicable retirement policy, the Expiry Date of a Stock Option that had vested on the date such Participant ceases to be an Eligible Person will be the earlier of the Expiry Date shown on the relevant Notice of Grant and the date one hundred and
eighty (180) days following the date such Participant ceases to be an Eligible Person. The Stock Options that are outstanding but unvested on the date such Participant ceases to be an Eligible Person will immediately terminate and become null, void
and of no effect 

  

	 	(d)	Voluntary Resignation, Termination of Employment or Ceasing to be a Consultant. In the event a Participant ceases to be an Eligible Person as a result of
(i) his or her voluntary resignation, (ii) termination, whether with cause or without cause, from any position or employment with the Company or its Affiliates (other than his or her retirement), or (iii) the termination of the
Participant’s service agreement, whether for breach of agreement or otherwise, then the Expiry Date of a Stock Option that had vested on the date such Participant ceases to be an Eligible Person will be the earlier of the Expiry Date shown on
the relevant Notice of Grant and the date thirty (30) days following the date such Participant ceases to be an Eligible Person. The Stock Options that are outstanding but unvested on the date such Participant ceases to be an Eligible Person
will, subject to Section 5.1, immediately terminate and become null, void and of no effect. For purposes of the Plan, a Participant’s employment shall conclusively be deemed to have ceased on the date that such Participant ceases to be
actually and actively employed by the Company or its Affiliates (and for greater certainty shall not include any notice period required by any applicable statute or common law). 

 

	 	(e)	Ceasing to be a Director – In the event that a Participant who is a director of the Company (and not an employee or senior officer of the Company or any of

one hundred and eighty (180) days following the date such Participant ceases to be an Eligible Person. The Stock Options that are outstanding but unvested on the date such Participant ceases to be a director will, subject to Section 5.1,
immediately terminate and become null, void and of no effect. 

  
 - 7 -

	 	(f)	Discretion of Board - Notwithstanding Section 2.5(a), (b), (c), (d) or (e) above, but subject to applicable laws, rules and regulations of any
applicable Stock Exchange or Governmental Entity, the Board may, in its sole discretion, extend the Expiry Date of any Stock Options in whole or in part. 

  

	2.6.	Notice of Grant 

 Each
Stock Option must be confirmed, and will be governed, by a Notice of Grant signed by the Company and the Participant. 
  

	2.7.	Shareholder Approval 

Where required by the Stock Exchange or any Governmental Entity, shareholder approval to the grant of Stock Options shall be obtained
prior to the exercise of Stock Options granted by the Company. 
  

	2.8.	Payment of Exercise Price; Exercise of Stock Options 

  

	 	(a)	Stock Options may only be exercised by the Participant or his or her legal representative. Participants may exercise their Stock Options, subject to the restrictions
set out below, to acquire Shares by delivering to the Company a notice of option exercise (the “Exercise Notice”), substantially in the form attached hereto as Schedule “B”, together with a bank draft or certified cheque
in an amount equal to the aggregate Exercise Price of the Shares to be purchased pursuant to the exercise of Stock Options. 

  

	 	(b)	Notwithstanding Section 2.8(a) hereof, but subject to any adjustments contemplated by Section 5.2, Stock Options may not be exercised unless the aggregate
purchase price of the Shares acquired on exercise of such Stock Options is greater than or equal to US$1,000. 

  

	 	(c)	As soon as practicable following the receipt of the Exercise Notice and a bank draft or certified cheque in accordance with Section 2.8(a), the Company will
deliver to the Participant a certificate for the Shares so purchased. 

  

	 	(d)	The issuance of Shares by the Company to a Participant pursuant to the exercise of any Stock Option is subject to compliance with all applicable laws, rules and
regulations of all Governmental Entities applicable to the issuance and distribution of such Shares and to the requirements of any Stock Exchange on which the Shares may be listed or quoted, including any requirements with respect to the legending
of certificates representing the Shares issued pursuant to the exercise of any Stock Option. The Participant agrees: (i) to comply with all such laws, rules, regulations and requirements, (ii) to furnish to the Company any information,
report and/or undertakings required to comply with all such laws, rules, regulations and requirements, and (iii) to fully cooperate with the Company in complying with such laws, rules, regulations and requirements. 

 

	 	(e)	Upon the exercise of Stock Options, Eligible Persons who are employed by the Company or an Affiliate shall have withheld at source all income, social security and other
payroll taxes and withholdings required by law on the gain realized upon the exercise. 

  
 - 8 -

	2.9.	Amendment of Option Plan 

  

	(a)	The Board may, subject to any necessary regulatory approval, at its discretion from time to time, amend the Plan and the terms and conditions of any Stock Option
previously granted and, without limiting the generality of the foregoing, may make such amendment for the purpose of complying with any changes in any relevant law, rule, regulation, regulatory requirement or requirement of the Stock Exchange, or
for any other purpose which may be permitted by law, provided always that any such amendment will not alter the terms or conditions of, or impair any right of any Participant pursuant to any Stock Option awarded prior to such amendment without the
consent of such Participant, unless such amendment or alteration is required by applicable law, any applicable Stock Exchange or Governmental Entity. 

  

	(b)	Notwithstanding Section 2.9, the Board shall be required to obtain shareholder approval in order to: (i) increase the maximum number of Shares issuable under
the Plan, (ii) reduce the exercise price or purchase price of any Stock Option, (iii) extend the term of any Stock Option, (iv) make a change to the class of persons eligible to participate under the Plan, or (v) make any
amendment which would permit any Stock Option granted under the Plan to be transferable or assignable other than by will or under succession laws (estate settlement). 

 

	2.10.	Assignment of Stock Options 

 Stock Options (and any rights thereunder) are not assignable or Transferable. Any purported assignment or Transfer of Stock Options will not be recognized by the Company and will result in the immediate
expiry and termination of any such Stock Options and any rights relating thereto. 
  

	2.11	Alternative Share Compensation Arrangements 

 Notwithstanding any other provision of this Plan, the Board may, in its discretion, enter into alternative share compensation arrangements with non-resident directors of the Company if the Board
determines that, as a result of the tax consequences of Stock Option grants under this Plan to such non-resident directors, the tax consequences to such non-resident directors are materially adverse to such non-resident directors as compared to the
tax consequences of Stock Option grants to directors that are not nonresidents. In such circumstances the Board may choose to structure an alternative share compensation arrangement that does not provide material adverse tax consequences to such
non-resident directors, but that is substantially economically equivalent, in the Board’s determination, to the grant of Stock Options under the Plan and is not otherwise materially prejudicial to the Company. For greater certainty, any Shares
issued pursuant to any alternative share compensation arrangements under this Section 2.11 shall be considered to be Stock Options for the purposes of determining the number of Shares issuable pursuant to this Plan. 

  
 - 9 -

	ARTICLE 3	ASSUMPTION OR SUBSTITUTION OF STOCK OPTIONS 

  

	3.1.	Substitution 

  

	 	(a)	In the event of a Substitution Event, any surviving or acquiring corporation must, unless Article 4 applies: 

 

	 	(i)	assume any Stock Option outstanding under the Plan on substantially the same economic terms and conditions as the Plan; or 

 

	 	(ii)	substitute or replace similar stock options (including an award to acquire the same consideration paid to the securityholders of the Company in the transaction
effecting the Substitution Event) for those Stock Options outstanding under the Plan on substantially the same economic terms and conditions as the Plan. 

  

	 	(b)	In the event any surviving or acquiring Company neglects or refuses (as determined by the Board, acting reasonably) to assume any Stock Options or to substitute or
replace similar stock options for those outstanding Stock Options under the Plan in connection with a Substitution Event, then with respect to any Stock Options held by Participants, the vesting of such Stock Options (and, if applicable, the time
during which such Stock Options may be exercised) will automatically and without further action by the Board or the Company be immediately accelerated so that such Stock Options will be fully vested. In addition, in such event, the Board may
determine that outstanding Stock Options will terminate if not exercised (if applicable) at or prior to such Substitution Event. 

  

	 	(c)	No fractional Shares or other security will be issued upon the exercise of any Stock Option and, accordingly, if as a result of a Substitution Event or otherwise, a
Participant would become entitled to a fractional Share or other security, such Participant will have the right to acquire only the next lowest whole number of Shares or other security and no payment or other adjustment will be made with respect to
the fractional interest so disregarded; provided, however, that a cash payment equal to the value of all fractional interests disregarded pursuant to this Section 3.1(c) shall be made to a Participant if the number of Stock Options so
disregarded exceeds five percent (5%) of the total number of Stock Options exercised by such Participant. 

  

	 	(d)	 Notwithstanding any other provision of this Plan, in the event of a potential Substitution Event, the Board may, in its discretion: (i) terminate,
conditionally or otherwise and on such terms as it sees fit, the Stock Options not exercised following successful completion of such Substitution Event; and (ii) accelerate, conditionally or otherwise and on such terms as it sees fit, the
Vesting Date or otherwise modify the terms of the Stock Options to assist the Participants to obtain the advantage of holding Shares during the Substitution Event. If the 

  
 - 10 -

	 	
Substitution Event referred to in this Article 3 is not completed during the time specified therein (as the same may be extended), the Stock Options which vested pursuant to this Article 3 must
be returned by the Participant to the Company and will be reinstated as unvested Stock Options and the original terms applicable to such Stock Options will apply. If any of the Stock Options that vested pursuant to this Article 3 were exercised,
such Shares must be returned to the Company for cancellation. The determination of the Board in respect of any such Substitution Event will for the purposes of this Plan be final, conclusive and binding. 

 

	ARTICLE 4	TAKE-OVER BIDS 

  

	4.1.	Take-over Bids 

  

	 	(a)	In the event of a “potential change of control following a take-over bid” (as defined herein), the Board may, in its discretion, conditionally or
otherwise and on such terms as it sees fit, accelerate the Vesting Date of all of a Participant’s unvested Stock Options to a date prior to the expiry date of such bid or offer, such that all of a Participant’s Stock Options will
immediately vest at such time and the Vesting Date in connection with such Stock Options will be adjusted accordingly. In such event, all Stock Options so vested will be exercisable, conditionally or otherwise, from such date until their respective
Expiry Dates so as to permit the Participant to tender the Shares received upon such exercise pursuant to the bid or offer. For purposes of this Article 4, a “potential change of control following a take-over bid” will be deemed to
occur upon a formal bid or tender offer for Shares being made as a result of which the offeror and its affiliates would, if successful, beneficially own, directly or indirectly, fifty percent (50%) or more of the Shares then outstanding.

  

	 	(b)	Notwithstanding any other provisions of this Plan, in the event of a potential change of control following a take-over bid, the Board will have the power, if determined
appropriate (i) to terminate, conditionally or otherwise and on such terms as it sees fit, the Stock Options not exercised following successful completion of such event, and/or (ii) to modify the terms of the Stock Options, conditionally
or otherwise and on such terms as it sees fit, in order to assist the Participants to tender their securities into the take-over bid, including for greater certainty permitting such Participants to exercise their Stock Options on a
“cashless” basis. For greater certainty, in the event that the acquiring entity acquires one hundred percent (100%) of the outstanding Shares following the take-over bid, the Board will have the power, if determined appropriate, to
terminate the Stock Options not exercised upon the expiry of the time period for tendering to the acquiring entity for purchase. 

  

	 	(c)	 If the take-over bid referred to in Section 4.1(a) is not completed within the time specified therein (as the same may be extended), the Stock
Options that vested pursuant to Section 4.1(a) (if any) must be returned by the Participant to the Company and will be reinstated as unvested Stock Options and the original terms applicable to such Stock Options will apply. If any of the Stock
Options that vested pursuant to this Section 4.1(a) (if any) were exercised, such Shares 

  
 - 11 -

	 	
must be returned to the Company for cancellation. The determination of the Board with respect to any such event will for the purposes of this Plan be final, conclusive and binding.

  

	ARTICLE 5	MISCELLANEOUS 

  

	5.1.	Involuntary Termination 

In the event of a Substitution Event or a change of control (as defined below) and upon an Involuntary Termination of the Participant at
any time within the ninety day (90) day period prior to or the one hundred and eighty (180) day period following the date of completion of the transaction effecting such Substitution Event or change of control, all of a Participant’s
unvested Stock Options will immediately vest, and the Vesting Date in connection with such Stock Options will be adjusted accordingly. For the purposes of this section 5.1, a “change of control” will be deemed to occur upon a formal bid or
tender offer for Shares being made as a result of which the offeror and its affiliates acquires beneficial ownership (directly or indirectly) of fifty percent (50%) or more of the Shares then outstanding, or upon any issuance of Shares by the
Company (whether by way of public offering or private placement) that results in a single shareholder acquiring beneficial ownership (directly or indirectly) of fifty percent (50%) or more of the Shares outstanding after such issuance (provided
that such shareholder did not, at the time of such issuance, have beneficial ownership, direct or indirect, of fifty percent (50%) or more of the Shares). 
  

	5.2	Capital Adjustments 

 If
there is any change in the outstanding Shares by reason of a stock dividend or split, recapitalization, consolidation, combination or exchange of shares, reclassification, conversion or other fundamental corporate change, the Board will make,
subject to any prior approval required of the Stock Exchange or other applicable Governmental Entities, if any, an appropriate substitution or adjustment to the Shares or other securities of the Company, including in (i) the number or kind of
shares or other securities reserved for issuance pursuant to this Plan; and (ii) the exercise price of those unexercised Stock Options; provided, however, that no substitution or adjustment will obligate the Company to issue fractional Shares
upon the exercise of a Stock Option. 
  

	5.3.	Non-Exclusivity 

 Nothing
contained herein will prevent the Board from adopting other or additional compensation arrangements for the benefit of any Eligible Person or Participant, subject to any required Stock Exchange, regulatory or shareholder approval. 

 

	5.4.	Termination 

  

	 	(a)	The Board may amend, suspend or terminate this Plan or any portion thereof at any time in accordance with applicable legislation, and subject to any required regulatory
or shareholder approval. Subject to Articles 3 and 4 hereof, no amendment, suspension or termination will alter or impair any Stock Options under the Plan, or any rights pursuant thereto, granted previously to any Participant without the consent of
that Participant. 

  
 - 12 -

	 	(b)	If this Plan is terminated, the provisions of this Plan and any administrative guidelines, and other rules adopted by the Board and in force at the time of this Plan,
will continue in effect as long as any Stock Options under the Plan or any rights pursuant thereto remain outstanding. However, notwithstanding the termination of the Plan, the Board may make any amendments to the Plan or Stock Options it would be
entitled to make if the Plan were still in effect. 

  

	5.5.	Compliance with Legislation 

 The Board may postpone or adjust the exercise of any Stock Option or the issue of any Shares pursuant to this Plan as the Board in its discretion may deem necessary in order to permit the Company to
effect or maintain qualification of this Plan or the Shares issuable pursuant thereto under the securities laws of any applicable jurisdiction, or to determine that the Shares and this Plan are exempt from such registration. The Company is not
obligated by any provision of this Plan or any grant hereunder to sell or issue shares in violation of any applicable law. In addition, if the Shares are listed on a Stock Exchange, the Company will have no obligation to issue any Shares pursuant to
this Plan unless the Shares have been duly listed, upon official notice of issuance, on the Stock Exchange on which the Shares are listed for trading. 
  

	5.6.	Effective Date 

 This Plan
will become effective upon the approval of the Plan by the Board. 
  

	5.7	No Other Rights 

 Nothing herein contained and no grant of Stock Options pursuant to the Plan shall be deemed to give any Eligible Person the right to be retained as an Eligible Person or the right to be retained as an
employee, senior officer, director or Consultant of the Company. For greater certainty, a period of notice, if any, or payment in lieu thereof, upon termination of employment, wrongful or otherwise, shall not be considered as extending the period of
employment for the purposes of the Plan. Stock Options are not Shares, and the grant of a Stock Option to an Eligible Person does not entitle such Eligible Person to any rights as a shareholder of the Company.

 - 2 -Second Amendment to Approach Resources Inc. 2007 Stock Incentive Plan

 Exhibit 10.1 
 SECOND AMENDMENT TO THE 
 APPROACH RESOURCES INC. 

2007 STOCK INCENTIVE PLAN 
 This Second Amendment (the “Second Amendment”) to the Approach Resources Inc. 2007 Stock Incentive Plan, as amended from time to time (the “Plan”), is made
effective as of May 31, 2012 (the “Amendment Effective Date”), by Approach Resources Inc., a Delaware corporation (“Approach”), subject to approval by Approach’s stockholders. 

W I T N E S S E T H: 
 WHEREAS, Approach established the Plan, originally effective as of June 28, 2007, under which Approach is authorized to grant equity-based incentive awards to certain employees and service providers
of Approach and its subsidiaries; 
 WHEREAS, Section 14.1 of the Plan provides that Approach’s board of directors
(the “Board”) may amend the Plan subject to, in certain circumstances, the approval of the holders of at least a majority of Approach’s shares of common stock; 

WHEREAS, the Board now desires to amend the Plan in the manner contemplated hereby, subject to approval by Approach’s shareholders
at the Company’s 2012 annual meeting, to (a) delete the Plan’s “evergreen” provision in Section 4.1(a), (b) provide for a maximum number of shares available for grant of Awards under the Plan after the Amendment
Effective Date at 2,100,000, (c) extend the term of the Plan until May 30, 2022, and (d) remove the Plan provisions permitting (i) shares tendered by an option holder to pay for the exercise of an option and
(ii) shares withheld for taxes, in either case, to be recycled back into the Plan for future Awards; and 
 WHEREAS,
capitalized terms used but not defined herein shall have the same meaning as set forth in the Plan. 
 NOW, THEREFORE, the Plan
shall be amended as of the Amendment Effective Date as set forth below: 
 1. Section 1.3 of the Plan is hereby deleted and
replaced in its entirety with the following: 
 1.3 Effectiveness and Term. This Plan was originally
effective on June 28, 2007 (the “Effective Date”), the date of its approval by the holders of at least a majority of the shares of Common Stock. The Plan was subsequently amended by the Board effective December 31, 2008. The Plan
was subsequently amended by the Board and approved by Approach’s shareholders effective May 31, 2012. Unless terminated earlier by the Board pursuant to Section 14.1, this Plan shall terminate on May 30, 2022. 

2. Section 4.1(a) of the Plan is hereby deleted and replaced in its entirety with the following: 

(a) Subject to adjustment as provided in Section 4.2, the maximum number of shares of Common Stock that shall be
available for grant of Awards under the Plan, as of May 31, 2012, shall not exceed 2,100,000 shares. If an Award granted under the Plan, including Awards granted and outstanding as of the Amendment Effective Date, expires, is forfeited
or becomes unexercisable for any reason without having been exercised in full, the undelivered shares of Common Stock which were subject to the Award shall, unless the Plan shall have been terminated, become available for future Awards under the
Plan. 

 3. Section 4.3(f) of the Plan is hereby deleted and replaced in its entirety with the
following: 
 (f) Payment of Exercise Price and Withholding Taxes. The number of shares available for
grant of Awards under the Plan shall not be increased by (i) the number of shares of Common Stock delivered or withheld to pay the exercise price of any Award, or (ii) the number of shares of Common Stock delivered or withheld to
pay withholding taxes payable upon exercise, vesting or payment of any Award. 
 4. Except as set forth above, the Plan shall
continue to read in its current state. 
 IN WITNESS WHEREOF, Approach has caused the execution of this Second Amendment by its
duly authorized officer, effective as of the Amendment Effective Date.
