FOURTH AMENDED AND RESTATED 2007 EQUITY INCENTIVE PLAN 
 ARTICLE I 
 INTRODUCTION 

1.1 Amendment and Restatement. The Luca Technologies Inc. 2007 Equity Incentive Plan (the “Original
Plan”) for certain key employees of the Company (as hereinafter defined), certain consultants and advisors to the Company, and certain non-employee directors of the Company, was approved by the Board of Directors and
stockholders of Luca Technologies Inc. on April 20, 2007. The Luca Technologies Inc. Amended and Restated 2007 Equity Incentive Plan (the “Amended and Restated Plan”), which amended and
restated the Original Plan in its entirety, was approved by the Board of Directors and stockholders of Luca Technologies Inc. on September 10, 2007. The Luca Technologies Inc. Second Amended and Restated 2007 Equity Incentive Plan (the
“Second Amended and Restated Plan”), which amended and restated the Amended and Restated Plan in its entirety, was approved by the Board of Directors and stockholders of Luca Technologies Inc. on December 1, 2008. The
Second Amended and Restated Plan was further amended and restated in its entirety pursuant to the terms set forth in the Luca Technologies Inc. Third Amended and Restated 2007 Equity Incentive Plan. The Luca Technologies Inc. Third Amended and
Restated 2007 Equity Incentive Plan is hereby amended and restated in its entirety pursuant to the terms set forth in the Luca Technologies Inc. Fourth Amended and Restated 2007 Equity Incentive Plan (as further amended, restated, supplemented or
otherwise modified from time to time, the “Plan”). The Plan permits the grant of incentive stock options within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended,
non-qualified stock options, restricted stock awards, and other grants of stock-based and cash awards including, without limitation, stock appreciation rights, performance awards and restricted stock units to certain key employees of the Company,
certain consultants and advisors to the Company, and certain non-employee directors of the Company as provided herein. 
 1.2
Purposes. The purposes of the Plan are to provide those who are selected for participation in the Plan with added incentives to continue in the long-term service of the Company and to create in such persons a more direct interest in the
future success of the operations of the Company by relating incentive compensation to increases in stockholder value, so that the income of those participating in the Plan is more closely aligned with the income of the Company’s stockholders.
The Plan is also designed to provide a financial incentive that will help the Company attract, retain and motivate the most qualified employees, consultants, advisors and non-employee directors.

of the Company (or the Successor) to discharge or dismiss the Participant from the Service of the Company (or the Successor) for any other acts or omissions, but such other acts or omissions shall not be deemed, for purposes of the Plan, to

determinations, interpretations and other actions of the Committee pursuant to the provisions of the Plan shall be binding and conclusive for all purposes and on all persons. 
 3.2 Delegation by Committee. Subject to applicable law, regulations or any exchange requirements, the Committee may, from time to time, delegate, to specified officers of the Company, the power and
authority to grant Awards under the Plan to specified groups of Eligible Employees, Eligible Consultants and Eligible Non-Employee Directors, subject to such restrictions and conditions as the Committee, in its sole discretion, may impose. The
delegation shall be as broad or as narrow as the Committee shall determine. To the extent that the Committee has delegated the authority to determine certain terms and conditions of an Award, all references in the Plan to the Committee’s
exercise of authority in determining such terms and conditions shall be construed to include the officer or officers to whom the Committee has delegated the power and authority to make such determination. The power and authority to grant Awards to
any Eligible Employee or Eligible Consultant or Eligible Non-Employee Director who is covered by Section 16(b) of the Exchange Act shall not be delegated by the Committee and may not be delegated if it is required by Code Section 162(m)
but only to the extent Code Section 162(m) would require it to meet the performance-based exception and there is not otherwise an applicable exception under Code Section 162(m) such as the transition period following an initial public
offering in Treasury Regulation 1.162-27(f)(1). 
 3.3 Contractual Limitations. The Committee shall in exercising its
discretion under the Plan comply with all contractual obligations of the Company in effect from time to time, whether contained in the Company’s Certificate of Incorporation, bylaws, or other binding contract. 

ARTICLE IV 

STOCK SUBJECT TO THE PLAN 
 4.1 Number of Shares. Subject to adjustment as provided in Section 4.3, the maximum aggregate number of Shares that may be issued under the Plan pursuant to Awards is 4,000,000 Shares. Any
Shares with respect to Options or other Awards that are cancelled, expired, forfeited, settled in cash, withheld for taxes or the purchase price or otherwise terminated without issuing the underlying shares of Stock to the Participant, shall remain
available for future grant under the Plan, and if issued but unvested shares of Restricted Stock 

  

							
		 	Luca Technologies Inc. Fourth Amended and Restated 2007 Equity Incentive Plan	  	 	7	  

 
are forfeited or withheld for the purchase price or taxes, such shares shall become available for future grant under the Plan. Notwithstanding anything to the contrary contained herein, no Award
granted hereunder shall become void or otherwise be adversely affected solely because of a change in the number of Shares of the Company that are issued and outstanding from time to time, provided that changes to the issued and outstanding Shares
may result in adjustments to outstanding Awards in accordance with the provisions of this Article IV. Subject to adjustment as provided in Article IV, to the extent permitted under Section 422 of the Code, the maximum number of Shares that may
be issued under Incentive Options is 4,000,000 Shares. The Shares may be either authorized and unissued Shares or previously issued Shares acquired by the Company. The maximum numbers may be increased from time to time by approval of the Board
and by the stockholders of the Company. The Company shall at all times during the term of the Plan and while any Awards are outstanding retain as authorized and unissued Stock at least the number of Shares from time to time required under the
provisions of the Plan, or otherwise assure itself of its ability to perform its obligations hereunder. Any Shares which remain unissued and which are not subject to outstanding Awards at the termination of the Plan shall cease to be subject
to the Plan. 
 4.2 Individual Limits on Awards. Subject to adjustment as provided in Section 4.3, and
only to the extent required to meet the performance-based exception requirements of Code Section 162(m) and further provided that there is not an exception to the performance-based requirements of Code Section 162(m) such as the transition
period following an initial public offering as provided in Treasury Regulation 162-27(f)(1), the maximum number of shares of Stock that may be issuable under Awards granted to any one individual during any twelve month period shall not exceed
750,000 shares of Stock (subject to adjustment in the manner as provided in this Article IV), and the maximum amount of cash compensation that may be paid under Awards intended to qualify for the performance-based compensation exception under
Section 162(m) of the Code granted to any one individual during any twelve month period may not exceed $10 million. The limitations set forth in this Article IV are intended to permit certain Awards under the Plan to constitute
“performance-based” compensation for purposes of Section 162(m) of the Code and only apply to the extent that the transition period in Treasury Regulation 1.162m-27(f)(1) is not applicable for an Award. 

4.3 Adjustments for Stock Split, Stock Dividend, Etc. If the Company shall at any time increase or decrease the number of
its outstanding Shares or change in any way the rights and privileges of such Shares by means of the payment of a stock dividend or any other distribution upon such Shares payable in Stock, or through a stock split, subdivision, consolidation,
combination, reclassification or recapitalization involving the Stock, then in relation to the Stock that is affected by one or more of the above events, the numbers, exercise price, rights and privileges of the following shall be increased,
decreased or changed in like manner as if they had been issued and outstanding, fully paid and nonassessable at the time of such occurrence: (i) the Shares as to which Awards may be granted under the Plan, (ii) the Shares then included in
each outstanding Award granted hereunder, (iii) the maximum number of Shares available for grant to any one person pursuant to Section 4.2, (iv) the maximum number of Shares available for grant pursuant to Incentive Options, and
(v) the number of Shares subject to a delegation of authority under Section 3.2 of this Plan. Subject to the following sentence, any fractional share resulting from such adjustment shall be rounded up to the next whole share. Such
proportionate adjustments will be made for purposes of making sure that to the extent possible, the fair value of 

  

							
		 	Luca Technologies Inc. Fourth Amended and Restated 2007 Equity Incentive Plan	  	 	8	  

 
the Awards after the subdivision, consolidation or dividend is equal to the fair value before the change and shall be made in accordance with Code Sections 422, 424 and 409 to the extent
applicable. 
 4.4 Other Distributions and Changes in the Stock. If: 

(a) The Company shall at any time distribute with respect to the Stock assets or securities of persons other than the Company (excluding
(i) cash or (ii) distributions referred to in Section 4.3), or 
 (b) The Company shall at any time grant to the
holders of its Stock rights to subscribe pro rata for additional shares thereof or for any other securities of the Company, or 

(c) There shall be any other change (except as described in Section 4.3) in the number or kind of outstanding Shares or of any stock
or other securities into which the Stock shall be changed or for which it shall have been exchanged, and if the Committee shall in its discretion determine that the event described in subsection (a) or (b) above equitably requires an
adjustment in the number or kind of Shares subject to an Option or other Award, an adjustment in the Option Price, or the taking of any other action by the Committee, including without limitation, the setting aside of any property for delivery to
the Participant upon the exercise of an Option or the full vesting of an Award, then such adjustments shall be made, or other action shall be taken, by the Committee and shall be effective for all purposes of the Plan and on each outstanding Option
or Award that involves the particular type of stock for which a change was effected. Notwithstanding the foregoing provisions of this Section 4.4, pursuant to Section 8.3 below, a Participant holding Stock received as a Restricted Stock
Award shall have the right to receive all amounts, including cash and property of any kind, distributed with respect to the Stock after such Restricted Stock Award was granted. 

4.5 General Adjustment Rules. No adjustment or substitution provided for in this Article IV shall require the Company to
sell a fractional Share under any Option, SAR or other Award or otherwise issue a fractional Share, and the total substitution or adjustment with respect to each Option, SAR and other Award shall be limited by deleting any fractional Share. In the
case of any substitution or adjustment with regards to an Option or SAR, the aggregate Option Price or exercise price of a SAR for the total number of Shares then subject to an Option or SAR shall remain unchanged but the Option Price per Share
under each such Option or SAR shall be equitably adjusted by the Committee to reflect the greater or lesser number of Shares or other securities into which the Stock subject to the Option or SAR may have been changed, and appropriate adjustments
shall be made to other Awards to reflect any such substitution or adjustment. All adjustments or substitutions shall be made in accordance with Code Sections 422, 424 and 409A to the extent applicable to an Award. 

4.6 Determination by the Committee, Etc. Adjustments under this Article IV shall be made by the Committee, whose determinations
with regard thereto shall be final and binding upon all parties thereto. 
 ARTICLE V 

CORPORATE REORGANIZATION; CHANGE IN CONTROL 
 5.1 Default Provisions. Unless explicitly provided otherwise in an Award Agreement, and subject to Section 5.3 below: 

  

							
		 	Luca Technologies Inc. Fourth Amended and Restated 2007 Equity Incentive Plan	  	 	9	  

 (a) The Shares subject to each Option or SAR outstanding under the Plan at the time of a
Change in Control shall automatically vest in full so that each such Option or SAR shall, immediately prior to the Change in Control, become exercisable for all of the Shares at the time subject to that Option or SAR and may be exercised for any or
all of those Shares as fully-vested Shares of Stock. However, the Shares subject to an outstanding Option or SAR shall not vest in full on such an accelerated basis if and to the extent: (i) such Option or SAR is assumed by the
successor corporation (or a parent thereof) (the “Successor”) or otherwise continued in full force and effect pursuant to the terms of the Change in Control transaction and any repurchase rights of the Company with respect to
the unvested Shares subject to such Option or SAR are concurrently assigned to such Successor or otherwise continued in effect, or (ii) such Option or SAR is to be replaced with a cash incentive program of the Company or any Successor which
preserves the spread between the Option or SAR Price and the Fair Market Value of the unvested Shares subject to such Option or SAR at the time of the closing of the Change in Control and provides for subsequent payout of that spread in accordance
with the vesting schedule applicable to those unvested Shares, or (iii) the acceleration of such Option or SAR is subject to other limitations imposed by the Committee at the time of the Option or SAR grant. 

(b) All outstanding Repurchase Rights with respect to unvested Shares purchased pursuant to any Option or SAR shall also
automatically terminate, and the Shares subject to those terminated rights shall immediately vest in full, immediately prior to the Change in Control, except to the extent: (i) any of the Repurchase Rights are assigned to the Successor or
otherwise continued in full force and effect pursuant to the terms of the Change in Control transaction or (ii) such accelerated vesting is precluded by other limitations imposed by the Committee at the time the Repurchase Right is issued.

 (c) All outstanding Forfeiture Restrictions with respect to Restricted Stock Awards shall also automatically terminate, and
the Shares of Stock subject to those terminated Forfeiture Restrictions shall immediately vest in full, immediately prior to the Change in Control, except to the extent: (i) the Forfeiture Restrictions are maintained by the Successor and
continued in full force and effect pursuant to the terms of the Change in Control transaction or (ii) such accelerated vesting is precluded by other limitations imposed by the Committee at the time the Restricted Stock Award is issued.

 (d) Immediately following the consummation of the Change in Control, all outstanding Options or SARs shall terminate and
cease to be outstanding, except to the extent assumed by the Successor or otherwise continued in effect pursuant to the terms of the Change in Control transaction. 
 5.2 Assumption or Substitution of Options. To the extent any Option or SAR is assumed in connection with a Change in Control or otherwise continued in effect, such Option or SAR shall be
appropriately adjusted, immediately after such Change in Control, to apply to the number and class of securities which would have been issuable to the Participant in consummation of such Change in Control, had the Option or SAR been exercised
immediately prior to such Change in Control. Appropriate adjustments shall also be made to (i) the number and class of securities available for issuance under the Option or SAR following the consummation of such Change in Control and
(ii) the exercise price payable per share under each outstanding Option or SAR, provided the aggregate exercise price payable for such securities shall remain the same. To the extent the actual holders of the Company’s outstanding Stock
receive cash consideration for their Stock in consummation of the Change in Control, the Successor may, in connection with the assumption of the outstanding Options and SARs under this Plan, substitute one or more shares of its own common stock with
a fair market value equivalent to the cash consideration paid per Share of Stock in such Change in Control. Any 

  

							
		 	Luca Technologies Inc. Fourth Amended and Restated 2007 Equity Incentive Plan	  	 	10	  

 
adjustment for assumption or substitution shall be in accordance with Code Sections 422, 424 and 409A to the extent applicable. 

5.3 Provisions Applicable at the Discretion of the Committee. 

(a) Notwithstanding anything herein to the contrary, the Committee shall have the discretion, exercisable either at the time an Award is
granted or issued or at any time while the Award remains outstanding, to structure the Award so that it shall automatically accelerate and vest in full upon the occurrence of a Change in Control (and any Forfeiture Restrictions or Repurchase Rights
of the Company with respect to unvested Shares received pursuant to the Award shall immediately terminate), whether or not the Award is to be assumed in the Change in Control or the Forfeiture Restrictions or Repurchase Rights of the Company would
otherwise continue in effect pursuant to the Change in Control. 
 (b) The Committee shall also have full power and authority,
exercisable either at the time an Award is granted or at any time while the Award remains outstanding, to structure such Award so that all or a portion of the Shares subject to such Award will automatically vest on an accelerated basis should the
Participant’s Service terminate by reason of an Involuntary Termination within a designated period (not to exceed eighteen (18) months) following any Change in Control in which the Award is assumed or otherwise continued in effect and the
Repurchase Rights applicable to the Shares subject to such Award do not otherwise terminate. Any Award so accelerated shall remain exercisable for the fully-vested Shares subject to such Award until the expiration or sooner termination of the
Exercise Period. In addition, the Committee may provide that one or more of the Company’s outstanding Repurchase Rights with respect to Shares held by the Participant at the time of such Involuntary Termination shall immediately terminate on an
accelerated basis, and the Shares subject to those terminated rights shall accordingly vest at that time. 
 (c) The Committee
shall also have full power and authority, exercisable either at the time the Restricted Stock Award is issued or at any time while the Restricted Stock Award remains outstanding, to provide that all or a portion of the Forfeiture Restrictions with
respect to such Restricted Stock Award shall automatically terminate on an accelerated basis, and the Shares subject to those terminated Forfeiture Restrictions shall immediately vest, in the event the Participant’s Service should terminate by
reason of an Involuntary Termination within a designated period (not to exceed eighteen (18) months) following any Change in Control in which those Forfeiture Restrictions are assigned to the Successor or otherwise continued in full force and
effect. 
 (d) The Committee shall also have full power and authority, exercisable at the time an Option or SAR is granted or at
any time while an Option or SAR remains outstanding, to provide that the Option or SAR shall be deemed automatically exercised on a net basis immediately prior to a Change in Control if (i) the Option Price (or exercise price for a SAR) is less
than the then-current Fair Market Value per Share, and (ii) the Shares subject to the Option or SAR are vested (including vesting by reason of the Change in Control). Upon such net exercise, the Option Holder shall be entitled to a number of
Shares computed using the following formula: 
  

					
	X =    	  	Y (A–B)	  	
	  	A	  	

  

					
	Where:	  	X =	    	the number of Shares to be issued to the Option Holder;
			
		  	Y =	    	the number of Shares purchasable under the Option or SAR immediately prior to the Change in Control;

  

							
		 	Luca Technologies Inc. Fourth Amended and Restated 2007 Equity Incentive Plan	  	 	11	  

							
		 		  	A =	    	the then-current Fair Market Value of one Share of Stock; and
				
		 		  	B =	    	the per-Share Option Price of the Option (or the per-Share exercise price for a SAR).

 In no event shall the Committee be required to issue any fractional Shares. 

(e) The Committee shall also have full power and authority, exercisable at the time an Option or SAR is granted or at any time while an
Option or SAR remains outstanding, to provide that the Option or SAR, if outstanding immediately prior to a Change in Control and then having an Option Price or SAR exercise price less than the current Fair Market Value per Share, shall be
automatically cancelled at such time in exchange for a cash payment equal to the product of (i) the number of vested Shares then subject to the Option or SAR (including Shares that become vested as a result of the Change in Control) multiplied
by (ii) the excess of the (x) Fair Market Value of a Share on the date of the Change in Control over (y) the Option Price or SAR exercise price. 
 (f) In addition, the Committee, acting in its sole discretion without the consent or approval of any Participant, may affect one or more of the following alternatives, which alternatives may vary among
individual Participants and which may vary among Awards held by any individual Participant: (i) require the mandatory surrender to the Company by selected Participants of some or all of the outstanding Options, stock-settled Restricted Stock
Units and stock-settled SARs held by such Participants as of a date, before or after such Change in Control, specified by the Committee, in which event the Committee shall thereupon cancel such Awards and the Company shall pay (or cause to be paid)
to each such Participant an amount of cash per share equal to the excess, if any, of the amount calculated in Subparagraph (g) below (the “Change in Control Value”) of the shares subject to such Awards over the exercise
price(s), if any, under such Awards for such shares, or (ii) provide that the number and class of shares of Stock covered by such Awards shall be adjusted so that such Awards shall thereafter cover securities of the Successor or other property
(including, without limitation, cash) as determined by the Committee in its sole discretion. The Committee need not take the same action with respect to all outstanding Awards or to all outstanding Awards of the same type. Notwithstanding any other
provision in this Article V, the Committee shall have full power and authority, exercisable at the time an Award is granted or at any time while the Award remains outstanding, to provide for or take any other Change in Control related action with
respect to an Award as the Committee deems appropriate, and to the extent applicable, in accordance with the Code Sections 162(m) and 409A. 
 (g) For the purposes of clause (i) in Subparagraph (f) above, the “Change in Control Value” shall equal the amount determined in clause (i), (ii) or (iii), whichever is
applicable, as follows: (i) the per share price offered to stockholders of the Company in any such merger, consolidation, sale of assets or dissolution transaction, (ii) the price per share offered to stockholders of the Company in any
tender offer or exchange offer whereby a Change in Control takes place, or (iii) if such Change in Control occurs other than pursuant to a tender or exchange offer, the fair market value per share of the shares into which such Awards being
surrendered are exercisable or payable, as determined by the Committee as of the date determined by the Committee to be the date of cancellation and surrender of such Awards. In the event that the consideration offered to stockholders of the Company
in any transaction described above consists of anything other than cash, the Committee shall determine the fair cash equivalent of the portion of the consideration offered which is other than cash. 

(h) With respect to any vested and unvested Options and SARs for which the Option Price or exercise price is greater than the Fair Market
Value for such Shares immediately prior to a Change in Control, the Committee in its discretion may cancel such Awards in their entirety without the Participant’s consent and without paying any consideration therefore.

 ARTICLE VI 
 PARTICIPATION 
 Participants in the Plan shall be those Eligible Employees
who, in the judgment of the Committee, are performing, or during the term of their incentive arrangement will perform, vital services in the management, operation and development of the Company, and significantly contribute, or are expected to
significantly contribute, to the achievement of long-term corporate economic objectives. Eligible Consultants shall be selected from those consultants and advisors to the Company who are performing services important to the operation and growth of
the Company. All Eligible Non-Employee Directors selected by the Board may participate in the Plan. Participants may be granted from time to time one or more Awards; provided, however, that the grant of each such Award shall be separately approved
by the Committee and receipt of one such Award shall not result in automatic receipt of any other Award. Upon determination by the Committee that an Award is to be granted to a Participant, written notice shall be given to such person, specifying
the terms, conditions, rights and duties related thereto. Each Participant shall, if required by the Committee, enter into an agreement with the Company, in such form as the Committee shall determine and which is consistent with the provisions of
the Plan, specifying such terms, conditions, rights and duties. Awards shall be deemed to be granted as of the date specified in the grant resolution of the Committee, which date shall be the date of any related agreement with the Participant. In
the event of any inconsistency between the provisions of the Plan and any such agreement entered into hereunder, the provisions of the Plan shall govern. 
 ARTICLE VII 
 OPTIONS 

7.1 Grant of Options. Coincident with or following designation for participation in the Plan, a Participant may be granted
one or more Options. The Committee in its sole discretion shall designate whether an Option is an Incentive Option or a Non-Qualified Option; provided, however, that only Non-Qualified Options may be granted to Eligible Consultants and Eligible
Non-Employee Directors. The Committee may grant both an Incentive Option and a Non-Qualified Option to an Eligible Employee at the same time or at different times. Incentive Options and Non-Qualified Options, whether granted at the same time or at
different times, shall be deemed to have been awarded in separate grants and shall be clearly identified, and in no event shall the exercise of one Option affect the right to exercise any other Option or affect the number of Shares for which any
other Option may be exercised. An Option shall be considered as having been granted on the date specified in the grant resolution of the Committee. 
 7.2 Stock Option Agreements. Each Option granted under the Plan shall be evidenced by a written stock option agreement (an “Option Agreement”). An Option Agreement
shall be issued by the Company in the name of the Participant to whom the Option is granted (the “Option Holder”) and in such form as may be approved by the Committee. The Option Agreement shall incorporate and conform to the
conditions set forth in this Section 7.2 as well as such other terms and conditions that are not inconsistent as the Committee may consider appropriate in each case. 
 (a) Number of Shares. Each Option Agreement shall state that it covers a specified number of Shares, as determined by the Committee. 

(b) Price. The price at which each Share covered by an Option may be purchased (the “Option
Price”) shall be determined in each case by the Committee and set forth in the Option 

  

							
		 	Luca Technologies Inc. Fourth Amended and Restated 2007 Equity Incentive Plan	  	 	13	  

 
Agreement, but in no event shall the Option Price be less than 100 percent of the Fair Market Value of one Share of Stock on the date the Option is granted. 

(c) Duration of Options; Vesting. Each Option Agreement shall state the Exercise Period applicable to the Option, which
must end, in all cases, not more than ten years from the date the Option is granted. Each Option Holder shall become vested in the Shares underlying the Option in such installments and over such period or periods of time, if any, or upon such
events, as are determined by the Committee in its discretion and set forth in the Option Agreement. 
 The Option shall
generally become exercisable, in whole or in part, at the same time or times as the Shares underlying the Option vest; provided, however, that the Committee may grant Options that are immediately exercisable in whole or in part. Any unvested Shares
received by the Option Holder upon early exercise of the Option in accordance with the preceding sentence shall be subject to the Company’s right of repurchase, as follows. 

Should the Option Holder cease Service while holding unvested shares, the Company shall have the right to repurchase any or all of those
unvested Shares at a price per share equal to the Option Price (the “Repurchase Rights”). The Company shall be entitled to exercise its right to repurchase such unvested Shares by written notice to the Option
Holder sent within ninety (90) days after the time of Option Holder’s cessation of Service, or (if later) during the ninety (90)-day period following the execution date of any written stock purchase agreement executed by the Company and
the Option Holder. The notice shall indicate the number of unvested Shares to be repurchased, the repurchase price to be paid per Share (which shall be a price per Share equal to the Option Price), and the date on which the repurchase is to be
effected, such date to be not more than thirty (30) days after the date of such notice. 
 (d) Termination of
Service, Death, Disability, Misconduct and Other. The Committee may specify the period, if any, during which an Option may be exercised following termination of the Option Holder’s Service. The effect of this subsection 7.2(d)
shall be limited to determining the consequences of a termination and nothing in this subsection 7.2(d) shall restrict or otherwise interfere with the Company’s discretion with respect to the termination of any individual’s Service.
If the Committee does not otherwise specify, the following shall apply: 
 (i) If the Option Holder becomes Disabled, the
Option may be exercised by the Option Holder within one year following the Option Holder’s termination of Service on account of Disability (provided that such exercise must occur within the Exercise Period), but not thereafter. In any such
case, the Option may be exercised only as to the Shares that had become vested on or before the date of the Option Holder’s termination of Service because of Disability. 
 (ii) If the Option Holder dies during the Exercise Period while still in Service of the Company or within the one-year period referred to in (i) above or the three-month period referred to in
(iii) below, the Option may be exercised by those entitled to do so under the Option Holder’s will or by the laws of descent and distribution within one year following the Option Holder’s death (provided that such exercise must occur
within the Exercise Period), but not thereafter. In any such case, the Option may be exercised only as to the Shares that had become vested on or before the date of the Option Holder’s death. 

(iii) If the Service of the Option Holder is terminated by either the Company or the Option Holder within the Exercise Period for any
reason other than Misconduct, Disability or death, the Option may be exercised by the Option Holder within three (3) months following the date of such termination (provided that such exercise must occur within the Exercise Period), but not
thereafter. 

  

							
		 	Luca Technologies Inc. Fourth Amended and Restated 2007 Equity Incentive Plan	  	 	14	  

 
In any such case, the Option may be exercised only as to the Shares that had become vested on or before the date of termination of Service. 

(iv) If the Service of the Option Holder is terminated by the Company within the Exercise Period for Misconduct, the Option shall
automatically terminate and thereafter be void for all purposes (without limitation of the foregoing, the Option shall no longer be exercisable for any Shares, whether vested or unvested, immediately upon and after such termination). 

(e) No Employment Right. Nothing in this Plan shall limit or impair the Company’s right to terminate the employment of
any employee or to terminate the consulting services of any consultant or advisor. 
 (f) Exercise and Payments.

 (i) Manner of Exercise. The method for exercising each Option granted hereunder shall be by delivery to the
Company of written notice specifying the number of Shares with respect to which such Option is exercised. The purchase of such Shares shall take place at the principal offices of the Company within thirty (30) days following delivery of such
notice, at which time the Option Price of the Shares shall be paid in full by any of the methods set forth below or a combination thereof. The Option shall be exercised when the Option Price for the number of Shares as to which the Option is
exercised is paid to the Company in full and any withholding obligations are satisfied. A properly executed certificate or certificates representing the Shares shall be delivered to or at the direction of the Option Holder upon payment therefore. If
Options on less than all Shares evidenced by an Option Agreement are exercised, the Company shall deliver a new Option Agreement evidencing the Option on the remaining Shares upon delivery of the Option Agreement for the Option being exercised.

 (ii) The Option Price shall be paid by any of the following methods, or any combination of the following methods, at the
election of the Option Holder, or by any other method approved by the Committee: 
 (A) in cash or by wire transfer of
immediately available funds; 
 (B) by certified check, cashier’s check, or other check acceptable to the Company, payable
to the order of the Company; 
 (C) if expressly permitted by a resolution of the Committee applicable to the Option at the
time of exercise (whether such resolution is applicable solely to the Option being exercised or is generally applicable to some or all Options outstanding under the Plan), by delivery to the Company of certificates representing the number of Shares
then owned by the Option Holder, the Fair Market Value of which equals the purchase price of the Shares purchased pursuant to the Option, properly endorsed for transfer to the Company; provided however, that no Option may be exercised by delivery to
the Company of certificates representing Shares, unless such Shares have been held by the Option Holder for such period of time as the Committee determines, if any; for purposes of this Plan, the Fair Market Value of any Shares delivered in payment
of the purchase price upon exercise of the Option shall be the Fair Market Value as of the exercise date; the exercise date shall be the day of delivery of the certificates for the Shares used as payment of the Option Price; or 

(D) if expressly permitted by the Committee, in its sole discretion, by delivery to the Company of irrevocable instructions directing
the Company to withhold from the purchased Shares a number of Shares having a Fair Market Value as of the exercise date equal to the aggregate Option Price of the purchased Shares. 

  

							
		 	Luca Technologies Inc. Fourth Amended and Restated 2007 Equity Incentive Plan	  	 	15	  

 (g) Date of Grant. An Option shall be considered as having been granted on the
date specified in the grant resolution of the Committee, or the date all corporate action for the grant is completed, if later. 

(h) Withholding.  
 (i) Non-Qualified Options. Upon exercise of an Option, the Option Holder shall make appropriate arrangements with the Company to provide for the amount of additional withholding required by
Sections 3102 and 3402 of the Code and applicable country and state income tax laws, including payment of such taxes through delivery of Shares of Stock or by withholding Shares to be issued under the Option, as provided in Article XIV.

 (ii) Incentive Options. If an Option Holder makes a disposition (as defined in Section 424(c) of the
Code) of any Shares acquired pursuant to the exercise of an Incentive Option prior to the expiration of two years from the date on which the Incentive Option was granted or prior to the expiration of one year from the date on which the Option was
exercised, the Option Holder shall send written notice to the Company at the Company’s principal place of business of the date of such disposition, the number of Shares disposed of, the amount of proceeds received from such disposition and any
other information relating to such disposition as the Company may reasonably request. The Option Holder shall, in the event of such a disposition, make appropriate arrangements with the Company to provide for the amount of additional withholding, if
any, required by Sections 3102 and 3402 of the Code and applicable state income tax laws. 
 7.3 Restrictions on
Incentive Options. 
 (a) $100,000 Per Year Limitation. The aggregate Fair Market Value of the
Shares with respect to which Incentive Options are exercisable for the first time by an Option Holder in any calendar year, under the Plan or otherwise, shall not exceed $100,000. For this purpose, the Fair Market Value of the Shares shall be
determined as of the date of grant of the Option and Incentive Options shall be taken into account in the order granted. The portion of any Incentive Option accelerated in connection with a Change in Control shall remain exercisable as an Incentive
Option only to the extent the above limitation is not exceeded. To the extent such dollar limitation is exceeded, the accelerated portion of such Incentive Option shall thereafter be exercisable as a Non-Qualified Option. 

(b) Ten Percent Stockholders. Incentive Options granted to an Option Holder who is the holder of record of 10% or more of

becomes the holder of record of such Shares, except as provided in Article IV.

 ARTICLE VIII 
 RESTRICTED STOCK AWARDS 
 8.1 Grant of Restricted Stock
Awards. Coincident with or following designation for participation in the Plan, the Committee may grant a Participant one or more Restricted Stock Awards consisting of Shares of Stock. The number of Shares granted as a Restricted Stock
Award shall be determined by the Committee. Each Restricted Stock Award granted under the Plan shall be evidenced by a written restricted stock agreement (a “Restricted Stock Agreement”). The Restricted Stock Agreement shall
incorporate and conform to the conditions set forth in this Article VIII as well as such other terms and conditions that are not inconsistent as the Committee may consider appropriate in each case. 

8.2 Restrictions. A Participant’s right to retain a Restricted Stock Award granted to him or her under
Section 8.1 shall be subject to such restrictions, including, but not limited to, his or her continuous Service for the Company for a restriction period specified by the Committee or the attainment of specified performance goals and objectives,
as may be established by the Committee with respect to such Award (the restrictions established by the Committee under this Section shall be known as the “Forfeiture Restrictions”). The Committee may in its sole discretion
provide for different Forfeiture Restrictions with respect to different Participants, to different Restricted Stock Awards, or to separate, designated portions of the Shares constituting a Restricted Stock Award. In the event of the death or
Disability of a Participant (except as otherwise provided in the Restricted Stock Agreement), all Forfeiture Restrictions then held by him or her shall lapse with respect to a pro rata part of each such Award based on the ratio between the
number of full months of Service completed at the time of termination of Service from the grant of each Award to the total number of months of Service required for such Award to be fully nonforfeitable, and such portion of each such Award shall
become fully nonforfeitable. The remaining portion of each such Award shall be forfeited and shall be immediately returned to the Company. If a Participant’s Service terminates for any other reason, any Shares as to which the Forfeiture
Restrictions have not been satisfied (or waived or accelerated as provided herein) shall be forfeited, and all Shares related thereto shall be immediately returned to the Company. 

8.3 Privileges of a Stockholder, Transferability. Unless otherwise provided in the Award Agreement, a Participant shall
have all voting, dividend, liquidation and other rights with respect to Stock (in accordance with its terms) received by him as a Restricted Stock Award under this Article VIII, subject to any Forfeiture Restrictions; provided, however, that the
Participant’s right to sell, encumber, or otherwise transfer such Stock shall be subject to the limitations of Section 11.2 and Article XII. 
 8.4 Enforcement of Restrictions. The Committee shall cause a legend to be placed on the Stock certificates issued pursuant to each Restricted Stock Award referring to the restrictions
provided by Sections 8.2 and 8.3 and, in addition, may in its sole discretion require one or more of the following methods of enforcing the restrictions referred to in Sections 8.2 and 8.3: 

(a) Requiring the Participant to keep the Stock certificates, duly endorsed, in the custody of the Company while the restrictions remain
in effect; or 

  

							
		 	Luca Technologies Inc. Fourth Amended and Restated 2007 Equity Incentive Plan	  	 	17	  

 (b) Requiring that the Stock certificates, duly endorsed, be held in the custody of a
third-party while the restrictions remain in effect. 
 ARTICLE IX 

OTHER GRANTS 
 From time to time during the duration of this Plan, the Board may, in its sole discretion, adopt one or more incentive compensation arrangements for Participants pursuant to which the Participants may
acquire Shares or receive cash based Awards, whether by purchase, outright grant, or otherwise. Any arrangement shall be subject to the general provisions of this Plan and all Shares issued pursuant to such arrangements shall be issued under this
Plan. Such Awards may include but shall not be limited to SARs, Performance Awards and other stock-based awards, such as Restricted Stock Units, and cash awards. 
 9.1 SARs 
 (a) Restrictions to be Established by the
Committee. SARs shall be subject to a restriction on disposition by the Participant and an obligation of the Participant to forfeit the SARs under certain circumstances, and any other restrictions determined by the Committee in its sole
discretion on the date of grant; provided, however, that such restrictions shall lapse upon: 
 (i) the attainment of one or
more Performance Measures; 
 (ii) the Participant’s continued employment with the Company or continued service as an
Eligible Non-Employee Director or Eligible Consultant for a specified period of time; 
 (iii) the occurrence of any event or
the satisfaction of any other condition specified by the Committee in its sole discretion; or 
 (iv) a combination of any of
the foregoing. 
 Each Award of a SAR may have different restrictions as established in the sole discretion of the Committee. 

(b) Other Terms and Conditions. At the time of grant, the Committee shall determine the vesting terms, Performance
Measures, if any, and at the time of grant, the Committee may, in its sole discretion, establish additional terms, conditions or restrictions relating to the SARs. Such terms, conditions or restrictions shall be set forth in the Award Agreement
delivered in conjunction with the Award. 
 (c) Exercise Price and Payment. Subject to adjustment as provided in
Article IV, the exercise price of the SARs shall not be less than the Fair Market Value of the shares of Stock underlying the SARs on the date of grant. Upon the lapse of the restrictions described in the Award Agreement, the Participant shall be
entitled to exercise his or her SARs at any time up until the end of the Exercise Period specified in the Award Agreement. The SARs, or portion thereof, shall only be exercised and any applicable taxes withheld, in accordance with such procedures as
are established or approved by the Committee. Upon exercise of the SAR, the Participant shall be entitled to receive payment in an amount equal to: (i) the difference between the Fair Market Value of the underlying shares of Stock subject to
the SARs on the date of exercise and the exercise price; times (ii) the number of shares of Stock with respect to which the SARs are exercised. Payment shall be made in the form of shares of Stock or cash, or a combination thereof, as
determined by the Committee. Cash shall be paid in a lump sum 

  

							
		 	Luca Technologies Inc. Fourth Amended and Restated 2007 Equity Incentive Plan	  	 	18	  

 
payment and shall be based on the Fair Market Value of the underlying Stock on the exercise date. The exercise price shall be payable by the Participant in cash; provided, however, that the
Committee in its sole discretion may allow the Participant to pay the exercise price by the withholding shares of Stock otherwise issuable upon exercise or with shares of Stock previously owned by the Participant or any combination of any of the
foregoing. All payments shall be subject to taxes and the applicable tax withholding requirements. 
 (d) Committee’s
Discretion to Accelerate Vesting of SARs. The Committee may, in its discretion and as of a date determined by the Committee, fully vest any portion or all of a Participant’s SARs and, upon such vesting, all restrictions applicable to
such SARs shall terminate as of such date. Any action by the Committee pursuant to this Subparagraph may vary among Participants and may vary among the SARs held by any Participant. 

(e) Award Agreement. SARs shall be evidenced by an Award Agreement in such form and containing such provisions not
inconsistent with the provisions of the Plan and under such terms as the Committee from time to time shall establish. The terms and provisions of the respective Award Agreements need not be identical. Subject to the consent of the Participant and
the restriction set forth in the last sentence of Subparagraph (d) above, the Committee may, in its sole discretion, amend an outstanding Award Agreement from time to time in any manner that is not inconsistent with the provisions of the Plan.

 (f) Service Recipient Stock. SARs that are intended to be excluded from the deferred compensation requirements
of Code Section 409A may only be granted if the SAR would be for “service recipient” common stock within the meaning of Code Section 409A, as determined by the Committee. 

(g) Stockholder Privileges. No Participant granted a SAR shall have any rights as a stockholder with respect to any shares
covered by the SAR until and unless the Participant becomes the holder of record of such Shares and no adjustments shall be made for dividends or other distributions or other rights as to which there is a record date preceding the date such
Participant becomes the holder of record of such Shares, except as provided in Article IV. 
 9.2 Performance Awards and
Other Stock-based Awards 
 (a) Performance Period. The Committee shall establish, with respect to and at the
time of each Performance Award, the maximum value of the Performance Award and the performance period over which the performance applicable to the Performance Award shall be measured. 

(b) Performance Measures and Other Criteria. A Performance Award shall be awarded to a Participant contingent upon future
performance of the Company, or a division or department of the Company Corporation, during the performance period. With respect to Performance Awards intended to qualify as performance-based compensation under Section 162(m) of the Code and no
other exception applies such as the transition period in Treasury Regulation 1.162-27(f)(1), the Committee shall establish the Performance Measures applicable to such performance either (i) prior to the beginning of the performance period or
(ii) within 90 days after the beginning of the performance period if the outcome of the performance targets is substantially uncertain at the time such targets are established, but not later than the date that 25% of the performance period has
elapsed and shall comply with the requirements of Code Section 162(m). The Committee shall provide that the vesting of the Performance Award will be based upon the Participant’s continued employment with the Company or continued service as
a Director or Eligible Consultant for a specified period of time and 

  

							
		 	Luca Technologies Inc. Fourth Amended and Restated 2007 Equity Incentive Plan	  	 	19	  

 (i) the attainment of one or more Performance Measures, or a combination thereof;

 (ii) the occurrence of any event or the satisfaction of any other criteria or condition specified by the Committee in its
sole discretion; or 
 (iii) a combination of any of the foregoing. 
 The Committee, in its sole discretion, may also provide for an adjustable Performance Award value-based upon the level of achievement of Performance Measures. 

(c) Award Criteria or Modification or Adjustments. In determining the value of a Performance Award, the Committee shall
take into account a Participant’s responsibility level, performance, potential, other Awards, total annual compensation and such other considerations as it deems appropriate. The Committee, in its sole discretion, may modify or provide for a
reduction in the value of a Participant’s Performance Award during the performance period; provided, however, with respect to Awards that are specified as to meet the performance-based exemption in Code Section 162(m), the Committee may
only modify or adjust such Awards in accordance with Code Section 162(m) for which the transition period in Treasury Regulation 1.162-27(f)(1) has expired. Notwithstanding the preceding provisions of this paragraph, the Committee may not take
any action described in this Subparagraph with respect to Awards designed to meet the exception for performance-based compensation under Section 162(m) of the Code; provided, however, this prohibition shall not apply to an acceleration of
vesting or payments pursuant to a Change in Control or due to death or Disability of the Participant or as otherwise permitted under Code Section 162(m). 

(d) Payment. Following the end of the performance period, the holder of a Performance Award shall be
entitled to receive payment as soon as practicable of an amount not exceeding the maximum value of the Performance Award, based on the achievement of the Performance Measures for such performance period, as determined and certified in writing by the
Committee. Payment of a Performance Award may be made in cash, Stock, Options or other equity compensation, or a combination thereof as determined by the Committee. Payment shall be made in a lump sum or in installments as prescribed in the Award
Agreement. If a Performance Award covering shares of Stock is to be paid in cash, such payment shall be based on the Fair Market Value of a share of Stock on the payment date. Unless otherwise provided in the Award Agreement, payment shall be made
no later than 2 1/2 months following the end of the
year in which the Performance Award vests, unless payment is to be made in installments, in which case such installments shall comply with the rules under Section 409A of the Code, if applicable. 

(e) Award Agreement. Each Performance Award shall be evidenced by an Award Agreement in such form and containing such
provisions not inconsistent with the provisions of the Plan and under such terms as the Committee from time to time shall establish. The terms and provisions of the respective Award Agreements need not be identical. Subject to the consent of the
Participant, the Committee may, in its sole discretion, amend an outstanding Award Agreement from time to time in any manner that is not inconsistent with the provisions of the Plan. 

9.3 Other Stock-Based Awards or Cash Award. The Committee may also grant to Participants any other stock-based Awards or cash
Awards, which shall consist of a right which is an Award denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to, shares of Stock as is deemed by the Committee to be consistent with the purposes of
the Plan and shall be payable in cash or Stock as determined by the Committee in the Award Agreement. Subject to the terms of the Plan, including the Performance Measures, if any, 

  

							
		 	Luca Technologies Inc. Fourth Amended and Restated 2007 Equity Incentive Plan	  	 	20	  

 
applicable to such Award, the Committee shall determine the terms and conditions of any such other stock-based or cash Award including, without limitation, vesting provisions as provided in the
Award Agreement. Notwithstanding any other provision of the Plan to the contrary, any other stock-based or cash Awards shall contain terms, as determined by the Committee in its sole discretion, that (i) are designed to be excluded from the
deferred compensation requirements of Code Section 409A or (ii) are designed to avoid adverse tax consequences under Section 409A should that Code section apply to such Award. The Committee may, in its discretion and as of a date
determined by the Committee, fully vest any portion or all of a Participant’s other stock-based or cash Awards and, upon such vesting, all restrictions applicable to such other stock-based or cash Awards shall terminate as of such date. Any
action by the Committee pursuant to this Subparagraph may vary among Participants and may vary among the other stock-based or cash Awards held by any Participant. Notwithstanding the preceding provisions of this paragraph, the Committee may not take
any action described in this Subparagraph with respect to other stock-based or cash Awards if such Award has been designed to meet the exception for performance-based compensation under Section 162(m) of the Code; provided, however, this
prohibition shall not apply to an acceleration pursuant to a Change in Control or due to death or Disability of the Participant or as otherwise permitted under Code Section 162(m). 

ARTICLE X 

INTERNATIONAL PARTICIPANTS 
 The Committee shall have the authority to adopt such procedures and sub-plans and grant Awards on such terms and conditions as the Committee determines necessary or appropriate to permit participation in
the Plan by individuals otherwise eligible to participate who reside or work outside of the United States, or otherwise to conform the terms or operation of the Plan to applicable requirements or practices of jurisdictions outside of the United
States. Notwithstanding anything in this Plan to the contrary, with respect to Participants holding one or more Awards under the Plan who reside or work outside the United States and who are not (and who are not expected to be) “covered
employees” within the meaning of Section 162(m) of the Code, the Committee may, in its sole discretion and without the consent of the Participants, amend the terms of the Plan (and any grant procedures or sub-plans, as applicable) or
Awards with respect to such Participants in order to conform such terms with the requirements of local law or to obtain more favorable tax or other treatment for the Participants or the Company. Awards granted or amended pursuant to the provisions
of this Article may contain terms and conditions that differ from the terms of such Awards otherwise provided elsewhere in the Plan. 
 ARTICLE XI 
 RIGHTS OF PARTICIPANTS 

11.1 Service. Nothing contained in the Plan or in any Option, or other Award granted under the Plan shall confer upon any
Participant any right with respect to the continuation of his employment by, or consulting relationship with, the Company, or interfere in any way with the right of the Company, subject to the terms of any separate employment agreement or other
contract to the contrary, at any time to terminate such services or to increase or decrease the compensation of the Participant from the rate in existence at the time of the grant of an Award. Whether an authorized leave of absence, or absence in
military or government service, shall constitute a termination of service shall be determined by the Committee at that time. 

11.2 Transferability. 

  

							
		 	Luca Technologies Inc. Fourth Amended and Restated 2007 Equity Incentive Plan	  	 	21	  

 (a) General Rule: No Lifetime Transfers. An Award shall not be transferable by
the Participant except (i) by will or pursuant to the laws of descent and distribution or (ii) except with respect to any Award other than an Incentive Option, to the Participant’s former spouse, pursuant to a Domestic Relations
Order. Except as otherwise provided by the terms of a Domestic Relations Order, an Option or SAR shall be exercisable during the Participant’s lifetime only by him or her, or in the event of Disability or incapacity, by his or her guardian or
legal representative. The Participant’s guardian or legal representative shall have all of the rights of the Participant under this Plan. 
 (b) No Assignment. No right or interest of any Participant in an Award granted pursuant to the Plan shall be assignable or transferable during the lifetime of the Participant, either
voluntarily or involuntarily, or be subjected to any lien, directly or indirectly, by operation of law, or otherwise, including execution, levy, garnishment, attachment, pledge or bankruptcy, except as set forth above. In the event the Award is
assigned or transferred in any manner contrary to terms of this Plan, then all Awards transferred or assigned shall immediately terminate. 
 11.3 No Plan Funding. Obligations to Participants under the Plan will not be funded, trusteed, insured or secured in any manner. The Participants under the Plan shall have no security interest in
any assets of the Company, and shall be only general creditors of the Company. 
 ARTICLE XII 

GENERAL RESTRICTIONS 
 12.1 Investment Representations. The Company may require any person to whom an Option, Restricted Stock Award, or other Award, is granted, as a condition of exercising such Option, receiving such
Restricted Stock Award, or such other Award to give written assurances in substance and form satisfactory to the Company and its counsel to the effect that such person is acquiring the Stock for his own account for investment and not with any
present intention of selling or otherwise distributing the same, and to such other effects as the Company deems necessary or appropriate in order to comply with Federal and applicable state securities laws. Legends evidencing such restrictions may
be placed on the Stock certificates. 
 12.2 Compliance with Securities Laws. Each Option, Restricted Stock Award grant,
or other Award shall be subject to the requirement that, if at any time counsel to the Company shall determine that the listing, registration or qualification of the shares subject to such Option, Restricted Stock Award, or other Award grant upon
any securities exchange or under any state or federal law, or the consent or approval of any governmental or regulatory body, is necessary as a condition of, or in connection with, the issuance or purchase of shares thereunder, such Option,
Restricted Stock Award or other Award may not be accepted or exercised in whole or in part unless such listing, registration, qualification, consent or approval shall have been effected or obtained on conditions acceptable to the Committee. Nothing
herein shall be deemed to require the Company to apply for or to obtain such listing, registration or qualification. 
 12.3
Changes in Accounting Rules. Except as provided otherwise at the time an Award is granted, notwithstanding any other provision of the Plan to the contrary, if, during the term of the Plan, any changes in the financial or tax accounting rules
applicable to Options, Restricted Stock Awards, or other Awards shall occur which, in the sole judgment of the Committee, may have a material adverse effect on the reported earnings, assets or liabilities of the Company, the 

  

							
		 	Luca Technologies Inc. Fourth Amended and Restated 2007 Equity Incentive Plan	  	 	22	  

 
Committee shall have the right and power to modify as necessary, any then outstanding and unexercised Options, outstanding Restricted Stock Awards, and other outstanding Awards as to which the
applicable services or other restrictions have not been satisfied. 
 12.4 Stockholder Agreements. If the Company has one
or more stockholder agreements in effect at the time of grant or exercise of an Award under the Plan, then the Committee shall, if the Company is contractually obligated to, and may, in its discretion, condition the grant or exercise (as applicable)
of any such Award upon execution by the Participant of such stockholder agreement(s), such that the Participant shall become a party to such stockholder agreements(s) concurrently with such grant or exercise (as applicable) of any such Award.

 12.5 Lock-Up Period. The Award Agreement (or any stock purchase or other agreement executed by the
Company and Participant at the time of exercise of the Award) may, as determined by the Committee in its sole discretion, include a provision requiring that, if requested by the Company or the representative of the underwriters of Stock (or other
securities) of the Company, the Participant shall not directly or indirectly sell, offer to sell, contract to sell, pledge, transfer or otherwise dispose of, make any short sale of, grant any option for the purchase or sale of, or enter into any
hedging or similar transaction with the same economic effect as a sale of, any Stock (or other securities) of the Company held by such Participant (other than those included for sale in the registration) for a period specified by the representative
of the underwriters of Stock (or other securities) of the Company not to exceed one hundred eighty (180) days following the effective date of a registration statement of the Company filed under the Securities Act. If requested by the Company or
the representative of the underwriters of Stock (or other securities) of the Company, the Participant would be required to enter into an agreement regarding his or her compliance with this requirement that will survive the term of the Award
Agreement. 
 ARTICLE XIII 
 PLAN AMENDMENT, MODIFICATION AND TERMINATION 
 The Board may also at any
time terminate the Plan, and from time to time may amend or modify the Plan provided, however, that no amendment or modification may become effective without approval of the amendment or modification by the stockholders, if stockholder approval is
required to enable the Plan to satisfy any applicable statutory or regulatory requirements, or if the Company, on the advice of counsel, determines that stockholder approval is otherwise necessary or desirable. 

Except as otherwise provided herein, no amendment, modification or termination of the Plan shall in any manner adversely affect any
Options, Restricted Stock Awards, or other Award theretofore granted under the Plan, without the consent of the Participant holding such Options, Restricted Stock Awards, or other Awards. 

ARTICLE XIV 

WITHHOLDING 
 14.1 Withholding Requirement. The Company’s obligations to deliver shares of Stock upon the exercise of any Option or SAR, the vesting of any Restricted Stock Award, the grant of 

  

							
		 	Luca Technologies Inc. Fourth Amended and Restated 2007 Equity Incentive Plan	  	 	23	  

 
Stock or pursuant to another Award shall be subject to the Participant’s satisfaction of all applicable federal, state, local and foreign income and other tax withholding requirements.

 14.2 Withholding With Stock. At the time the Committee grants an Option, Restricted Stock Award, other Award, or Stock
or at any time thereafter, it may, in its sole discretion, allow the tax withholding requirements to be met by (a) having the Company withhold from Shares otherwise issuable to the Participant Shares of Stock having a value equal to the amount
required to be withheld or such lesser amount; provided however, that the amount of Stock so withheld shall not exceed the minimum amount required to be withheld under the method of withholding that results in the smallest amount of withholding, or
(b) allowing a Participant to transfer to the Company a number of Shares of Stock that were acquired by the Participant for such period of time, if any, as the Committee determines and that have a value equal to the amount required to be
withheld or such lesser amount as may be elected by the Participant. The value of Shares of Stock to be withheld shall be based on the Fair Market Value of the Stock on the date that the amount of tax to be withheld is to be determined (the
“Tax Date”). In addition, if the Participant is an officer or director of the Company within the meaning of, and subject to, Section 16 of the Exchange Act (“Section
16”), the Participant must satisfy the requirements of such Section 16 and any applicable rules thereunder with respect to the use of Stock to satisfy such tax withholding obligation. 

ARTICLE XV 

REQUIREMENTS OF LAW 
 15.1 Requirements of Law. The issuance of Stock and the payment of cash pursuant to the Plan shall be subject to all applicable laws, rules and regulations. 

15.2 Federal Securities Law Requirements. If a Participant is an officer or director of the Company within the meaning of, and
subject to, Section 16, Awards granted hereunder shall be subject to all conditions required under Rule 16b-3, or any successor rule promulgated under the Exchange Act, to qualify the Award for any exception from the provisions of
Section 16(b) of the Exchange Act available under that Rule. Such conditions shall be set forth in the agreement with the Participant which describes the Award or other document evidencing or accompanying the Award. 

15.3 Section 409A. Notwithstanding anything in this Plan to the contrary, the Plan and Awards made under the Plan shall
comply with the requirements imposed by Section 409A of the Code to the maximum extent possible. If any Plan provision or Award would result in the imposition of an additional tax under Section 409A of the Code, the Company and the
Participant intend that the Plan provision or Award will be reformed to avoid imposition, to the extent possible, of the applicable tax and no action taken to comply with Section 409A of the Code shall be deemed to adversely affect the
Participant’s rights to an Award. The Participant further agrees that the Committee, in the exercise of its sole discretion and without the consent of the Participant, may amend or modify an Award in any manner and delay the payment of any
amounts payable pursuant to an Award to the minimum extent necessary to meet the requirements of Section 409A of the Code as the Committee deems appropriate or desirable.

 The existence of the Plan and the
Awards granted hereunder shall not affect in any way the right or power of the Board or the stockholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company’s or any Affiliated
Corporation’s capital structure or its business, any merger or consolidation of the Company or any Affiliated Corporation, any issue of debt or equity securities ahead of or affecting Stock or the rights thereof, the dissolution or liquidation
