THIRD 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
is hereby further amended and restated in its entirety pursuant to the terms set forth in this Luca Technologies Inc. Third 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 stock grants to certain key employees of the Company, to certain consultants and advisors to the Company, and certain non-employee directors of the Company. 

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.

 PLAN ADMINISTRATION 

3.1 General. The Plan shall be administered by the Committee. In accordance with the provisions of the Plan, the
Committee shall, in its sole discretion, select the Participants from among the Eligible Employees, Eligible Consultants and Eligible Non-Employee Directors, determine the Awards to be made pursuant to the Plan, or shares of Stock to be issued
thereunder and the time at which such Awards are to be made, fix the Option Price, period and manner in which an Option becomes exercisable, establish the duration and nature of Restricted Stock Award restrictions, establish the terms and conditions
applicable to, and establish such other terms and requirements of the various compensation incentives under the Plan as the Committee may deem necessary or desirable, and consistent with the terms of the Plan. The Committee shall determine the form
or forms of the agreements with Participants that shall evidence the particular provisions, terms, conditions, rights and duties of the Company and the Participants with respect to Awards granted pursuant to the Plan, which provisions need not be
identical except as may be provided herein; provided, however, that Eligible Consultants and Eligible Non-Employee Directors shall not be eligible to receive Incentive Options. The Committee may from time to time adopt such rules and regulations for
carrying out the purposes of the Plan as it may deem proper and in the best interests of the Company. The Committee may correct any defect, supply any omission or reconcile any inconsistency in the Plan or in any agreement entered into hereunder in
the manner and to the extent it shall deem expedient and it shall be the sole and final judge of such expediency. No member of the Committee shall be liable for any action or determination made in good faith. The 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. 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.

 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 4.4, the maximum aggregate number of Shares that may be issued under the Plan pursuant to Awards is 2,500,000 Shares.
Upon exercise of an option, the Shares issued upon exercise of such option shall no longer be considered to be subject to an outstanding Award or option for purposes of the immediately preceding sentence. 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 Section 4.4, to the extent permitted under Section 422 of the Code,
the maximum number of Shares that may be issued under Incentive Options is 2,500,000 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 if, in the opinion of counsel for the Company, stockholder approval is required. The Company shall at all times during the term of the Plan and while any Options 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. 

4.2 Limit on Options. Subject to adjustment as provided in Section 4.4, the maximum aggregate number of
Shares with respect to which a Participant may receive Options under the Plan during the term of the Plan is 750,000 Shares. The maximum number may be increased from time to time by approval of the Board and by the stockholders of the Company if, in
the opinion of counsel for the Company, stockholder approval is required. Stockholder approval shall not be required for increases solely pursuant to Section 4.4 below. 

4.3 Other Shares of Stock. Any Shares that are subject to an Option that expires or for any reason is terminated
unexercised, any Shares that are subject to an Award (other than an Option) and that are forfeited, and any Shares withheld for the payment of taxes or received by the Company as payment of the Option Price of an Option shall automatically become
available for use under the Plan. 
 4.4 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. 

  

					
	Luca Technologies Inc. Third Amended and Restated 2007 Equity Incentive Plan	  	 	6	  

 4.5 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 4.4), 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 4.4) 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 4.5, 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. 

4.6 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, or otherwise issue a fractional Share, and the total substitution or adjustment with respect to each Option and other Award shall be limited by deleting any fractional Share. In the case of any
substitution or adjustment with regards to an Option, the aggregate Option Price for the total number of Shares then subject to an Option shall remain unchanged but the Option Price per Share under each such Option 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 may have been changed, and appropriate adjustments shall be made to other Awards to reflect any such substitution or
adjustment. 
 4.7 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: 
 (a) The Shares subject to each Option outstanding under the Plan at the time of a
Change in Control shall automatically vest in full so that each such Option shall, immediately prior to the Change in Control, become exercisable for all of the Shares at the time subject to that Option 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 shall not vest in full on such an accelerated basis if and to the extent: (i) such Option 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 are 

  

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

 
concurrently assigned to such Successor or otherwise continued in effect, or (ii) such Option is to be replaced with a cash incentive program of the Company or any Successor which preserves
the spread between the Option Price and the Fair Market Value of the unvested Shares subject to such Option 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 is subject to other limitations imposed by the Committee at the time of the Option grant. 

(b) All outstanding Repurchase Rights with respect to unvested Shares purchased pursuant to any Option 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 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 is assumed in connection with a Change in
Control or otherwise continued in effect, such Option 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 Option Holder in consummation of
such Change in Control, had the Option 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 following the
consummation of such Change in Control and (ii) the exercise price payable per share under each outstanding Option, 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 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. 
 5.3 Provisions Applicable at the Discretion of the Committee. 
 (a) 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. 

  

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

 (b) The Committee shall also have full power and authority, exercisable
either at the time an Option is granted or at any time while the Option remains outstanding, to structure such Option so that all or a portion of the Shares subject to such Option will automatically vest on an accelerated basis should the Option
Holder’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 Option is assumed or otherwise continued in effect and the
Repurchase Rights applicable to the Shares subject to such Option do not otherwise terminate. Any Option so accelerated shall remain exercisable for the fully-vested Shares subject to such Option until the expiration or sooner termination of the
Option 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 Option Holder 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 is granted or at any time while an Option remains outstanding, to provide that the Option shall be deemed automatically exercised on a net basis immediately prior to a Change in Control if (i) the Option Price is less than the
then-current Fair Market Value per Share, and (ii) the Shares subject to the Option 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 immediately prior to the Change in Control;

				
		  	 A
	 	=	  	 the then-current Fair Market Value of one Share of Stock; and

				
		  	 B
	 	=	  	 the per-Share Option Price of the Option.

 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 is granted or at any time while an Option remains outstanding, to provide that the Option, if outstanding
immediately prior to a Change in Control and then having an Option 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 (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. 

  

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

 (f) 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. The Committee need not take the same action with respect to all outstanding Awards or to all outstanding Awards of the same type. 
 5.4 Company Actions. The grant of Awards under the Plan shall in no way affect the right of the Company to adjust, reclassify, reorganize or otherwise change its capital or business structure or to
merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. 
 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. 

  

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

 (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
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 Option 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 Option
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 Option 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 Option 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. 

  

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

 (iii) If the Service of the Option Holder is terminated by either the
Company or the Option Holder within the Option 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 Option 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 termination of Service. 

(iv) If the Service of the Option Holder is terminated by the Company within the Option 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), to the extent such Option Price is in excess of the par value of those Shares, by
delivering a full-recourse promissory note bearing interest at a market rate and secured by those Option Shares, and the payment schedule in effect for any such promissory note shall be established by the Committee in its sole discretion;

 (D) 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, 

  

					
	Luca Technologies Inc. Third Amended and Restated 2007 Equity Incentive Plan	  	 	12	  

 
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 
 (E) 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. 
 (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. 
 (i) Lock-Up Period. The Option Agreement (or any stock purchase or other agreement executed by the Company and Optionee at the time of exercise of the Option) 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 Option Holder 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 Option Holder (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 Option Holder would be required to enter into an agreement regarding his or her compliance with this requirement that will survive the term of the Option Agreement. 

  

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

 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 the outstanding stock of the Company shall have an Option Price equal to 110% of the Fair Market Value of the Shares on the date of grant of the Option and the Option Period for any such Option shall not exceed five
years. 
 7.4 Transferability. 

(a) General Rule: No Lifetime Transfers. An Option shall not be transferable by the Option
Holder except (i) by will or pursuant to the laws of descent and distribution or (ii) to the Option Holder’s former spouse, to the extent such assignment is pursuant to a Domestic Relations Order (provided that if the Option being
assigned pursuant to a Domestic Relations Order is an Incentive Option, such Incentive Option shall cease being an Incentive Option, and shall automatically convert to a Non-Qualified Option, upon such assignment). Except as otherwise provided by
the terms of a Domestic Relations Order, an Option shall be exercisable during the Option Holder’s lifetime only by him or her, or in the event of Disability or incapacity, by his or her guardian or legal representative. The Option
Holder’s guardian or legal representative shall have all of the rights of the Option Holder under this Plan. 
 (b) No Assignment. No right or interest of any Option Holder in an Option granted pursuant to the Plan shall be assignable or transferable during the lifetime of the Option
Holder, 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 Option is assigned or transferred in any manner contrary to terms of this Plan, then all Options transferred or assigned shall immediately terminate. 
 7.5 Stockholder Privileges. No Option Holder shall have any rights as a stockholder with respect to any Shares covered by an Option until and unless the Option Holder 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 Option Holder 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 

  

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

 
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. 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 Sections 11.2 and 14.2 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 
 (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, 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. 

  

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

 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 Nontransferability of Awards. Except as
provided otherwise at the time of grant or thereafter, or except as otherwise provided in a Domestic Relations Order, no right or interest of any Participant in a Restricted Stock Award (prior to the completion of the restriction period applicable
thereto), or other Award (excluding Options) granted pursuant to the Plan, shall be assignable or transferable during the lifetime of the Participant, either voluntarily or involuntarily, or subjected to any lien, directly or indirectly, by
operation of law, or otherwise, including execution, levy, garnishment, attachment, pledge or bankruptcy. In the event of a Participant’s death, a Participant’s rights and interests in Options, Restricted Stock Awards, and other Awards,
shall, to the extent provided in Article VII, Article VIII, and Article IX be transferable by will or the laws of descent and distribution, and payment of any amounts due under the Plan shall be made to, and exercise of any Options may be made by,
the Participant’s legal representatives, heirs or legatees. However, a Participant’s rights and interests in Options, Restricted Stock Awards, and other Awards shall be transferable to an Option Holder’s former spouse, to the extent
such assignment is pursuant to a Domestic Relations Order (provided that if the Option being assigned pursuant to a Domestic Relations Order is an Incentive Option, such Incentive Option shall cease being an Incentive Option, and shall automatically
convert to a Non-Qualified Option, upon such assignment). If in the opinion of the Committee a person entitled to payments or to exercise rights with respect to the Plan is disabled from caring for his affairs because of mental condition, physical
condition or age, payment due such person may be made to, and such rights shall be exercised by, such person’s guardian, conservator or other legal personal representative upon furnishing the Committee with evidence satisfactory to the
Committee of such status. 

  

					
	Luca Technologies Inc. Third Amended and Restated 2007 Equity Incentive Plan	  	 	16	  

 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 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.

 ARTICLE XIII 
 PLAN AMENDMENT, MODIFICATION AND TERMINATION 
 The Board
may at any time terminate, 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. 

  

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

 Subject to Section 15.3, 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, the vesting of any Restricted Stock Award, or the grant of Stock 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, grant the
Participant an election to pay all such amounts of tax withholding, or any part thereof, by electing (a) to have 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 as may be elected by the Participant; 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) 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

 (D) if expressly permitted by a resolution of the Committee applicable to
this Option at the time of exercise (whether such resolution is applicable solely to this Option 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 the Option may not be exercised by

15. Governing Law. The interpretation, performance and enforcement of this Agreement shall be governed by the laws of the State of
Delaware without resort to its conflict-of-laws rules. 
 16. Stockholder Approval. If the Option Shares covered by this
Agreement exceed, as of the Grant Date, the number of Shares of Stock which may be issued under the Plan as last approved by the Company’s stockholders, then the Option shall be void with respect to such excess Shares, unless stockholder
approval of an amendment sufficiently increasing the number of Shares of Stock issuable under the Plan is obtained in accordance with the provisions of the Plan.

Holder’s written consent.

Company (or any Affiliated Corporation employing or retaining Option Holder) or of Option Holder, which rights are hereby expressly reserved by each, to terminate Option Holder’s Service at any time for any reason, with or without cause. This

 20. Additional Terms Applicable to an Incentive Option. 

(a) In the event the Option is designated as an Incentive Option in the Grant Notice, the Option shall cease to qualify for favorable tax
treatment as an Incentive Option if (and to the extent) the Option is exercised for one or more Option Shares: (i) more than three (3) months after the date Option Holder ceases to be an employee for any reason other than death or
Disability or (ii) more than twelve (12) months after the date Option Holder ceases to be an employee by reason of Disability. Nothing in this Section shall require that the Option Holder be allowed to exercise this Option, in whole or in
part, after the expiration of the time periods specified in Section 5 hereof. 
 (b) If 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. 
 21. Withholding. The Company’s obligations to deliver shares of Stock upon the exercise of the Option shall be subject to the Option Holder’s satisfaction of all applicable
federal, state and local income and other tax withholding requirements. Upon exercise of the 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 state income tax laws. If expressly permitted by a resolution of the Committee applicable to this Option at the time of exercise (whether such resolution is applicable solely to this Option or
is generally applicable to some or all Options outstanding under the Plan) payment of such taxes may be made through delivery of Shares of Stock or by withholding Shares to be issued under the Option, as provided in Section 14.2 of the Plan.

 22. Tax Treatment; Section 409A. Option Holder may incur tax liability as a result of
the exercise of the Option or the disposition of Option Shares. Option Holder should consult his or her own tax adviser before exercising the Option or disposing of the Option Shares. 

Notwithstanding anything in this Agreement or the Plan to the contrary, the Plan, this Agreement and the Option granted hereunder are
intended to comply with the requirements imposed by Section 409A of the Code by establishing the Option Price at an amount equal to or greater than the Fair Market Value of a share of Stock on the Grant Date. However, notwithstanding the
Board’s determination of the Fair Market Value of a share of Stock for purposes of determining the Option Price, the taxing authorities may assert that the Fair Market Value of a share of Stock on the Grant Date was greater than the Option
Price. Under Section 409A of the Code, if the Option Price is less than the Fair Market Value of a Share on the Grant Date, the Option may be treated as a form of deferred compensation and Option Holder may be subject to an additional 20% tax,
plus interest. Option Holder is encouraged to consult a tax advisor regarding the potential impact of Section 409A of the Code. 

  
 8 

 Execution Copy 
  

 If any provision of this Agreement, the Plan or this Option would result in the
imposition of an additional tax under Section 409A of the Code, the Company and Option Holder intend that the provision of this Plan, the Agreement or this Option, as the case may be, 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 Option Holder’s interest in this Option. Option Holder further agrees that the Committee, in the exercise of
its sole discretion and without Option Holder’s consent, may amend or modify this Agreement in any manner and delay the payment of any amounts payable pursuant to this Agreement to the minimum extent necessary to meet the requirements of
Section 409A of the Code. The Company will provide Option Holder with notice of any such amendment or modification. 

23. Lock Up. Without limitation of the other provisions of this Agreement or the Plan (including without limitation
any such provisions relating to restrictions on transferability of the Option and/or the Option Share), the Option Holder hereby agrees that it will not, without the prior written consent of the managing underwriter, during the Market Stand-Off
Period (as defined below), (a) lend; offer; pledge; sell; contract to sell; sell any option or contract to purchase; purchase any option or contract to sell; grant any option, right, or warrant to purchase; or otherwise transfer or dispose of,
directly or indirectly, the Option or any of the Option Shares or other securities of the Company held immediately before the effective date of the registration statement for such offering or (b) enter into any swap or other arrangement that
transfers to another, in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause (a) or (b) above is to be settled by delivery of Stock or other securities, in
cash, or otherwise. The foregoing provisions of this Section 23 shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement. The underwriters in connection with such registration are intended third-party
beneficiaries of this Section 23 and shall have the right, power, and authority to enforce the provisions hereof as though they were a party hereto. The Option Holder further agrees to execute such agreements as may be reasonably requested by
the underwriters in connection with such registration that are consistent with this Section 23 or that are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions
with respect to the shares of Stock or other securities of the Option Holder (and transferees and assignees thereof) until the end of such restricted period. For purposes of this Section 23: (i) “IPO” means the
Company’s first underwritten public offering of its Common Stock under the Securities Act; and (ii) “Market Stand-Off Period” means the period of time commencing on the date of the final prospectus relating to the

(such period not to exceed (1) one hundred eighty (180) days in the case of the IPO, which period may be extended upon the request of the managing underwriter, to the extent required by any Financial Industry Regulatory Authority
(“FINRA”) rules, for an additional period of up to fifteen (15) days if the Company issues or proposes to issue an earnings or other public release within fifteen (15) days of the expiration of the 180-day lockup period,
or (2) ninety (90) days in the case of any registration other than the IPO, which period may be extended upon the request of the managing underwriter, to the extent required by any FINRA rules, for an additional period of up
