 FEEDSTOCK SUPPLY AGREEMENT 

THIS FEEDSTOCK SUPPLY AGREEMENT (“Agreement”) is made and entered into as of this 3rd day of September, 2010
(“Effective Date”), between Waste Management of Nevada, Inc., a Nevada corporation (“Supplier”), and Fulcrum Sierra BioFuels, LLC, a Delaware limited liability company (“Fulcrum”). Supplier and
Fulcrum are sometimes referred to herein jointly as the “Parties” and individually as a “Party.” 
 WHEREAS, Fulcrum intends to construct and operate a facility in Storey County, Nevada, for the production of ethanol and/or other bioproducts (the “Facility”). 

WHEREAS, Fulcrum and Supplier desire to enter into this Agreement under which Supplier shall supply and deliver, and Fulcrum shall
accept, specified quantities of Feedstock (as defined below), all in accordance with the terms and conditions set forth in this Agreement. 
 WHEREAS, Fulcrum and Supplier each acknowledge that Fulcrum’s processing technology to be deployed at the Facility has not yet been proven by Fulcrum on a large commercial scale, that Supplier is in
effect serving as an early stage “beta” customer, which may assist Fulcrum in validating and proving out its technology, and as a result of the risks to Supplier inherent in this relationship as well as the benefits to Fulcrum, the tipping
fees and certain other provisions set forth in this Agreement reflect an “early adopter” discount and other benefits to Supplier which may not be offered by Fulcrum to future feedstock suppliers at other Fulcrum facilities.

		 	5	 	Confidential

 
Representative Instructions for the following Month by no later than the twenty-fifth Day (25th) of each Month. Fulcrum shall update and deliver to the Supplier Scheduling Representative
revised Instructions on a daily basis. Within twenty (20) Days after the end of any Month, Fulcrum shall deliver (together with the monthly statements required under Section 3.2) to Supplier the final Instructions for such Month,
which will include the actual Tons of Feedstock delivered by Supplier and accepted by Fulcrum for such Month. 
 (b)
Deliveries of Feedstock. Subject to Article 7, from and after the Commercial Operation Date, Supplier or its Affiliates shall supply and deliver to Fulcrum at the Delivery Point, and Fulcrum shall accept at the Delivery Point, the
quantities of Feedstock specified in the Instructions. 
 (c) Interruptions. Each Party shall immediately notify the
other Party’s Scheduling Representative (by telephone with written notification as soon thereafter as is reasonably practicable) if such Party learns of any probable or actual interruption in the scheduled supply, delivery or acceptance of
Feedstock in accordance with the then-applicable Instructions. 
 2.3 Feedstock Priority; Feedstock Option. 

(a) Supplier Priority. Subject to Section 7.2 and the other terms herein, (i) Supplier shall as a matter of
first priority dedicate a sufficient amount of Feedstock collected or received by Supplier or its Affiliates within the Geographic Waste Shed to the satisfaction of amounts of Feedstock requested from time to time by Fulcrum, up to the Maximum
Deliverable Quantity, and (ii) Supplier and its Affiliates shall not use or allocate any such Feedstock for other purposes if such use or allocation would limit Supplier’s ability to deliver Feedstock in the amounts (up to the Maximum
Deliverable Quantity) requested by Fulcrum hereunder. Nothing herein is intended to prevent or limit Supplier from using, in its complete discretion, any Feedstock not requested by Fulcrum. 

(b) Fulcrum Priority. If Fulcrum requires any Feedstock for its Facility in excess of materials received by Fulcrum under the
Primary Supply Agreement, subject to the other provisions of this Agreement, Fulcrum shall schedule and accept such Feedstock (up to the then-applicable Maximum Deliverable Quantity) from Supplier to the extent required for Fulcrum’s Facility.
The Parties acknowledge that Fulcrum does not guarantee any specific level of Facility requirements for Feedstock and that nothing in this Agreement limits Fulcrum’s right to obtain Feedstock or material similar to Feedstock from one or more
Persons during any period in which Supplier is unable to deliver Feedstock in the quantities required from time to time by Fulcrum hereunder. 
 (c) Supplier’s Obligation to Process Feedstock. If Supplier secures for itself or its Affiliates the right to own or operate a new Materials Recovery Facility or other similar facility in the
Geographic Waste Shed, then the Parties shall in good faith endeavor to negotiate an amendment to this Agreement to incorporate terms and conditions (including appropriate economic arrangements) under which Supplier would further pre-sort and/or
pre-process Processable Feedstock so that it meets a mutually agreed specification for Feedstock tailored for Fulcrum’s Facility (“Supplier Processed Feedstock”). Any such amendment shall be subject to the approval of each
Party in its sole discretion, and if the Parties fail to reach mutual agreement on such an amendment, this Agreement shall continue in full force and effect unamended.

 2.4 Delivery Procedures. 

(a) Transportation. 
 (i) Responsibilities. Supplier shall have the sole responsibility, at its sole expense, for transporting the Feedstock to the Delivery Point. Fulcrum shall have the sole responsibility, at its sole
expense, for unloading the Feedstock at the Delivery Point. 
 (ii) No Direct Haul Feedstock. Fulcrum shall have the
right not to accept from Supplier’s haulers, and Supplier shall not deliver, any “direct-haul” Feedstock, meaning that prior to delivery at the Delivery Point, all Feedstock must be consolidated at a Transfer Station or a Materials
Recovery Facility into transfer trailers and will not be delivered in packer trucks. 
 (b) Deliveries. Supplier or its
Affiliates shall deliver all Feedstock to the Delivery Point. All such deliveries shall be completed in accordance with this Agreement, including the Instructions. 
 (c) Weighing Standards and Procedures. Fulcrum shall maintain and operate at the Delivery Point, in accordance with Law, a motor vehicle scale certified by the State of Nevada for the purpose of
determining the Tonnage of Feedstock delivered by Supplier at the Delivery Point. Fulcrum shall weigh and record inbound weights of all of Supplier’s delivery vehicles when the vehicles arrive at the Delivery Point and shall again weigh and
record the weights of such vehicles after such vehicles have deposited the Feedstock at the Delivery Point. Fulcrum shall test and calibrate all scales in accordance with Law, but at least every twelve (12) Months. Fulcrum shall provide
Supplier with paper or electronic copies of weigh tickets or receipts summarizing each delivery of Feedstock to the Delivery Point, including information specifying the date and time of delivery, identification of the delivery vehicle, weight of the
vehicle when loaded and weight of the vehicle after unloading. At any time the scales are unavailable, Fulcrum shall estimate the quantity of Feedstock delivered to the Facility on the basis of delivery vehicle volumes and historical records.

 (d) Facility Location Rules. Supplier shall require all transporters of Feedstock to the Facility Location to comply
with all Law, and to the extent not inconsistent with this Agreement, the Facility Location rules, as in effect from time to time. Fulcrum shall have the right to deny access to the Facility Location to any transporter that Fulcrum reasonably
believes does not or cannot comply with Law or Fulcrum’s Facility Location rules or presents a hazard or a material disruption to Fulcrum’s Facility Location. Supplier shall cause each transporter of Feedstock to the Facility Location to
execute and deliver such agreements or acknowledgments in favor of Fulcrum with respect to such transporter’s access to and entry upon the Facility Location as may be reasonably requested by Fulcrum from time to time. Supplier shall further
require each of its transporters making deliveries of Feedstock to the Facility Location to carry and maintain insurance with coverages and amounts reasonably designated by Fulcrum from time to time. 

(e) Turn-Around Time at the Facility. Fulcrum will use commercially reasonable efforts to ensure that the time spent by the
delivery vehicles unloading the Feedstock at the Delivery Point does not exceed thirty (30) minutes for any individual load of Feedstock. 

  

					
		 	7	 	Confidential

 (f) Scheduling Representatives. 

(i) Fulcrum Scheduling Representative. Fulcrum shall appoint an individual (the “Fulcrum Scheduling
Representative”) who shall serve as the primary Fulcrum representative under this Agreement with respect to the scheduling and acceptance of deliveries of Feedstock. The Fulcrum Scheduling Representative shall (i) have overall
responsibility for managing and coordinating the performance of Fulcrum’s obligations under this Agreement and (ii) be authorized to act for and on behalf of Fulcrum with respect to all scheduling and operational matters relating to this
Agreement. The Fulcrum Scheduling Representative may, upon notice to Supplier, delegate such of his or her responsibilities hereunder to other Fulcrum employees as the Fulcrum Scheduling Representative deems appropriate. Fulcrum may, upon notice to
Supplier given in accordance with Section 10.1, appoint a new individual to serve as the Fulcrum Scheduling Representative. 
 (ii) Supplier Scheduling Representative. Supplier shall appoint an individual (the “Supplier Scheduling Representative,” and together with the Fulcrum Scheduling Representative,
individually, a “Scheduling Representative”) who shall serve as the primary Supplier representative under this Agreement with respect to the scheduling and delivery of Feedstock. The Supplier Scheduling Representative shall
(i) have overall responsibility for managing and coordinating the performance of Supplier’s obligations under this Agreement and (ii) be authorized to act for and on behalf of Supplier with respect to all scheduling and operational
matters relating to this Agreement. The Supplier Scheduling Representative may, upon notice to Fulcrum, delegate such of his or her responsibilities hereunder to other Supplier employees as the Supplier Scheduling Representative deems appropriate.
Supplier may, upon notice to Fulcrum given in accordance with Section 10.1, appoint a new individual to serve as the Supplier Scheduling Representative. 
 (iii) Notices to Scheduling Representatives. Notwithstanding Section 10.1, notices, requests and other communications specifically relating to the scheduling, delivery and acceptance of
Feedstock at the Facility shall be made to the Party’s Scheduling Representative in the manner provided in this Section 2.4(f). Notices given under this Section 2.4(f) shall be in writing and (x) delivered
personally or (y) sent by confirmed facsimile transmission or electronic mail, with telephone confirmation to each Party’s Scheduling Representative at an address to be designated by such Party (along with a designation of such
Party’s initially appointed Scheduling Representative) no later than sixty (60) Days prior to the date of the first delivery of Feedstock expected hereunder. In the event of any emergency, Uncontrollable Circumstance or other unforeseen
event that immediately affects, or is reasonably expected to immediately affect, the scheduling, delivery or acceptance of Feedstock as contemplated under this Agreement, a Party shall as soon as reasonably practicable notify the other Party’s
Scheduling Representative in person or by telephone of the occurrence of such event, with written notice to follow promptly thereafter. Notices shall be effective when received by the other Party. A Party may change its address for notification
purposes by giving the other Party notice of the new address and the date upon which it shall become effective. 
 2.5
Compliance with Laws. Each Party shall comply with all Laws in carrying out its obligations under this Agreement. 
 2.6
Testing and Monitoring of Feedstock. Fulcrum shall have the right (but no obligation) to inspect or test any quantity of Feedstock delivered by Supplier at the Delivery Point, but Fulcrum’s exercise, or failure to exercise, such testing
and inspection rights shall not relieve Supplier of its responsibility to deliver Feedstock meeting the specifications of this 

  

					
		 	8	 	Confidential

 
Agreement. If, within a reasonable time following delivery, Fulcrum reasonably determines that any materials delivered by Supplier do not comply with the definition of Feedstock or otherwise with
the terms of this Agreement or cannot lawfully be processed by the Facility, Fulcrum may inform Supplier of its rejection (or revocation of acceptance) of such non-conforming materials (any such material, “Rejected Materials”), and
Supplier shall be solely responsible for the handling, loading, transportation and disposal of such Rejected Materials. Rejected Materials that are identified by Fulcrum and segregated prior to loading into the Facility’s front-end
sorting/shredding systems are herein referred to as “Primary Rejected Materials”, and Rejected Materials that are identified by Fulcrum and segregated after loading into the Facility’s front-end sorting/shredding systems are
herein referred to as “Secondary Rejected Materials”. The weight of any Primary Rejected Materials shall not, but the weight of any Secondary Rejected materials shall, be counted towards the Maximum Deliverable Quantity or the other
applicable Feedstock delivery or acceptance requirement amounts set forth in this Agreement. For the avoidance of doubt, the term “Rejected Materials” shall not include Non-Processable Residuals. Fulcrum shall provide notice to Supplier of
Fulcrum’s identification of any Rejected Materials and shall (subject to Section 2.8) afford Supplier a five (5) hour window to meet and confer with Fulcrum at the Facility to review the Rejected Materials, before any action is
taken to handle or otherwise manage such Rejected Materials. In the event that the Feedstock delivered by Supplier under this Agreement is co-mingled at the Facility with Feedstock from any other third party, then Fulcrum shall have the burden of
proving that properly Rejected Materials were in fact delivered by Supplier and not other third parties. 
 2.7 Title,
Possession and Risk of Loss. 
 (a) Feedstock. Title, possession and risk of loss of any or all Feedstock accepted
by Fulcrum for use at the Facility (including any non-conforming material which Fulcrum chooses to accept for processing) shall pass from Supplier to Fulcrum, and delivery shall be completed, when such Feedstock is unloaded from the delivery vehicle
at the Delivery Point, subject to Sections 2.6 and 2.8. If Fulcrum is in possession of Rejected Materials, title and risk of loss to such Rejected Materials shall not pass to Fulcrum at the Delivery Point but shall at all times remain
with Supplier, and Supplier shall be solely responsible for the handling, loading, transportation and disposal of such Rejected Materials following identification and segregation by Fulcrum. Such Rejected Materials shall be returned to Supplier at
the Facility, unless Supplier and Fulcrum agree otherwise. Supplier shall reimburse Fulcrum (within forty-five (45) Days after receipt of an invoice) for Fulcrum’s reasonable costs and expenses relating to the handling of (and, if any, the
loading, transportation and disposal of) any Rejected Materials (but not including any costs associated with the front-end sorting/shredding systems operated by Fulcrum). 
 (b) Documentation. Each Party shall provide those completed documents, shipping papers or manifests as are required for lawful transfer of Feedstock, Rejected Materials and Non-Processable
Residuals (as described below). 
 2.8 Non-Processable Residuals. The Parties acknowledge that a portion of the Feedstock
delivered by Supplier under this Agreement that is introduced into Fulcrum’s Facility will not be fully gasified by the Facility or otherwise will not result in ethanol or other bioproducts, and will result in vitreous or other non-Hazardous
Material residual byproducts (collectively, “Non-Processable Residuals”). Supplier shall collect all such Non-Processable Residuals (and Rejected Materials) derived from Supplier’s delivery of the Feedstock and generated by the
Facility and transport them to, and dispose of them at, Supplier’s [***] or other appropriate and lawful disposal site. Supplier shall have no obligation or

treatment. 

 
responsibility for Non-Processable Residuals or Rejected Materials derived from any Feedstock delivered by the Primary Supplier or any other third parties; however, Fulcrum may contract with
Supplier for the transportation and disposal of such materials at the [***] or other appropriate and lawful disposal site based upon terms mutually agreeable to the Parties. Fulcrum shall use commercially reasonable efforts to separate and track
Non-Processable Residuals and Rejected Materials at the Facility derived from Supplier’s Feedstock. The provisions of Sections 2.4 and 2.7 relating to delivery procedures, title, possession, risk of loss and transportation shall
generally apply to Supplier’s collection of the Non-Processable Residuals and Rejected Materials except: (a) Fulcrum shall have the right to designate a “Delivery Point” for the collection of the Non-Processable Residuals and
Rejected Materials in the Instructions, (b) Fulcrum shall be responsible for any transportation of the Non-Processable Residuals to, and loading Supplier’s vehicles at, such delivery point, and (c) title, possession and risk of loss
for the Non-Processable Residuals shall transfer from Fulcrum to Supplier when Supplier’s vehicles are loaded at such delivery point. 
 2.9 Feedstock Acknowledgements. Supplier agrees to use commercially reasonable efforts to ensure that all deliveries of materials hereunder meet the definition of Feedstock, all subject to and in
accordance with the provisions in this Agreement. However, Supplier makes no representation or warranty whatsoever regarding the energy value or suitability of any materials delivered for use in Fulcrum’s processing equipment, and any and all
such representations and warranties are disclaimed. Fulcrum shall bear all risk and responsibility, and Supplier shall not be subject to any liability or damage claims (including but not limited to consequential damages) due to the failure of
recycling markets or energy markets, failure of Fulcrum to produce a marketable product, or failure of Fulcrum to maintain all necessary construction and operations permits. Fulcrum also acknowledges that Supplier is under no obligation to
“pre-process,” sort or grind the Feedstock prior to delivery, that all Feedstock delivered by Supplier shall be in the form received by Supplier at the Transfer Station or Materials Recovery Facility, and that inevitably a portion of the
Feedstock delivered by Supplier will consist of a certain amount of materials that may become Rejected Materials. 
 2.10
Additional Feedstock Requirements and Supplier Option. 
 (a) Generally. If, at any time during the Term of this
Agreement, Fulcrum has any requirements for Feedstock, or contemplates any future requirements for Feedstock, in addition to the Feedstock actually provided or committed to be provided in the aggregate pursuant to the Primary Supply Agreement and
this Agreement combined (such additional requirements for Feedstock, whether resulting from Fulcrum’s construction of a Facility expansion or new facility, a current or contemplated shortfall in deliveries under the Primary Supply Agreement, or
any other cause whatsoever other than a shortfall in deliveries by Supplier hereunder or as provided in Section 2.10(e), are herein collectively referred to as “Additional Feedstock Requirements”), then, prior to
soliciting or accepting any such Additional Feedstock Requirements from the Primary Supplier or any other third party, Fulcrum shall offer Supplier the option to supply such Additional Feedstock Requirements through a temporary or permanent increase
to the Maximum Deliverable Quantity hereunder, all in accordance with this Section 2.10. 
 (b) Non-Exigent
Circumstances. In the event of Additional Feedstock Requirements arising out of an expansion of the Facility or Fulcrum’s construction a new Facility, the expiration of the Primary Supply Agreement, or other future potential Additional
Feedstock Requirements where there are no exigent circumstances, as covered by Section 2.10(c) below, Fulcrum shall provide a written notice and request to Supplier (an “Additional

Feedstock Request”) setting forth in reasonable detail (i) the reasons for the projected Additional Feedstock Requirements, (ii) the period during which such Additional
Feedstock Requirements are expected, (iii) Fulcrum’s proposed increase in the Maximum Deliverable Quantity hereunder to accommodate such Additional Feedstock Requirements and the period of such increase and (iv) any other specific
requirement hereunder applicable to such Additional Feedstock Requirements. For a period of forty-five (45) Days following receipt of an Additional Feedstock Request under this Section 2.10(b), Supplier shall have the right and
option to evaluate and either accept or reject such Additional Feedstock Request, such acceptance to be effected by countersigning and returning such Additional Feedstock Request to Fulcrum. Any such countersigned Additional Feedstock Request shall
be deemed to be an amendment to this Agreement. If Supplier fails to countersign and return any such Additional Feedstock Request to Fulcrum within such specified period, then Supplier shall for all purposes be deemed to have rejected such
Additional Feedstock Request, in which case, Fulcrum may contract with the Primary Supplier or other third parties to meet the Additional Feedstock Request, on the same or better terms (to Fulcrum) as offered to Supplier, provided that if Fulcrum
fails to enter into an agreement with a third party related to the Additional Feedstock Request within six (6) months from the date of Supplier’s rejection (or deemed rejection) of such Additional Feedstock Request, then Fulcrum shall
repeat the Additional Feedstock Request procedure described in this subsection before entering into a contract with a third party for the supply of the applicable Additional Feedstock Requirements. 

(c) Exigent Circumstances. The Parties acknowledge that exigent circumstances may arise where Fulcrum may have immediate needs
for Additional Feedstock Requirements (e.g., a temporary or permanent unexpected shortfall in Feedstock supplied under the Primary Supply Agreement). If, at any time during the Term of this Agreement, Fulcrum, in its sole judgment exercised in good
faith, determines that any such exigent circumstances exist, Fulcrum shall provide an Additional Feedstock Request to Supplier in the same manner and on the same terms and conditions as in preceding Section 2.10(b), except that along
with such Additional Feedstock Request Fulcrum also shall provide a written statement including (i) a written description of the exigent circumstances and (ii) the period of time (in Days or hours), determined by Fulcrum in its sole
judgment exercised in good faith, during which Supplier shall have to evaluate and either accept or reject such Additional Feedstock Request. The procedures in Section 2.10(b) shall be applicable to such Additional Feedstock Request,
except that the response time required by Supplier shall be as set forth in the notice described in the preceding sentence. 

(d) Failure to Accept an Additional Feedstock Request, Etc. Notwithstanding the foregoing or any other provisions of this
Agreement, Fulcrum shall be free to solicit and obtain Feedstock (including Additional Feedstock Requirements) from any other supplier or in any other manner determined in the sole discretion of Fulcrum if: (a) Supplier is in default or breach
of this Agreement, and such default or breach remains uncured after (i) notice to Supplier and (ii) a reasonable opportunity to cure, but only to the extent and for so long as providing such opportunity would not materially adversely
effect the continued operations of the Facility, (b) with respect to Additional Feedstock Requirements, Supplier fails to accept any Additional Feedstock Request within the time period required and otherwise in accordance with the provisions of
this Agreement or (c) Supplier fails to continue to supply Fulcrum with 100% of the Feedstock requested by Fulcrum from time to time hereunder up to the Maximum Deliverable Quantity, and fails to cure such deficiency after (i) notice to
Supplier and (ii) a reasonable opportunity to cure, but only to the extent and for so long as providing such opportunity would not materially adversely effect the continued operations of the Facility. 

  

					
		 	11	 	Confidential

 (e) Exception for [***]. Notwithstanding the above, if Fulcrum develops or owns
another facility in the Geographic Waste Shed to produce ethanol or other bioproducts using feedstock identical or similar to the Feedstock hereunder, and such new facility uses feedstock provided by, directed by or otherwise under the control of
the [***] from its facility located in [***], then (i) such feedstock used in such facility shall not be considered Additional Feedstock Requirements under this Agreement, (ii) Fulcrum shall not be obligated to issue an Additional
Feedstock Request hereunder, (iii) Fulcrum shall be free to use in such facility any and all feedstock that is provided by, directed by or otherwise under the control of the [***] and (iv) Fulcrum’s contractual arrangements to carry
out the foregoing shall be deemed not to violate any provision of Section 10.25. 
 ARTICLE III

written notice, whereupon this Agreement shall immediately terminate and no Party shall have any continuing obligations or liabilities to the other except as set forth in Section 10.16. 

4.4 Failure to Request Feedstock. Beginning six (6) months after the COD, if Fulcrum fails to request at least [***] of

satisfaction of Supplier that Fulcrum has remedied the circumstances giving rise to the shortfalls in Feedstock requests, then Supplier may at its option, at any time prior to the date that is ninety (90) Days following the expiration of such
sixty (60) Day period, terminate this Agreement by providing thirty (30) Days written notice to Fulcrum of such termination,

ARTICLE VI 

INDEMNITY 

6.1 General. Each Party shall indemnify, defend and hold harmless the other Party, and all of its Indemnified Parties, from and
against any and all Losses, which any or all of them may hereafter suffer, incur, be responsible for or pay as a result of: (a) bodily injuries (including death) to any person or (b) damage (including loss of use) to any property, in any
case under clauses (a) or (b) to the extent caused by, or arising out of, breach by the first Party of this Agreement, or any negligent act or omission or willful misconduct, or any violation or alleged violation of Laws by such first
Party or its employees, agents or subcontractors. 
 6.2 Environmental and Hazardous Materials Indemnification.

 (a) Indemnification by Fulcrum. Fulcrum shall indemnify, defend and hold harmless Supplier and all of Supplier’s
Indemnified Parties, from and against all Losses to which any of them may be subjected by reason of, or to the extent resulting from, any condition of the Facility or associated with the operation, maintenance or closure thereof, relating to
Hazardous Materials and other environmental damage or liability, including any one or more release or threatened release of any Hazardous Materials and water or ground water contamination therefrom and replacement or restoration of natural resources
arising from or related to Hazardous Materials, including any repair, cleanup or detoxification thereof, or preparation and implementation of any removal, remedial, response, closure or other plan with respect thereto (regardless of whether
undertaken due to governmental action). This indemnity of Supplier, its Affiliates, and its franchise customers by Fulcrum is intended to operate as an agreement pursuant to, but not limited to, Section 107(e) of the Comprehensive Environmental
Response, Compensation and Liability Act (42 U.S.C. Section 9607(e)) and any analogous statute under Nevada law, to insure, protect, hold harmless, defend and indemnify Supplier, its Affiliates and its franchise customers from liability in
accordance with this Section. Supplier, its Affiliates and its franchise customers do not hereby waive or surrender any other indemnity available to it under any applicable law. The indemnity in this Section 6.2(a) shall survive the
termination of this Agreement. 
 The indemnification and related obligations of Fulcrum set forth in this
Section 6.2(a) shall not apply to any Losses arising out of Hazardous Materials delivered to the Facility by Supplier, its Affiliates or any of their employees or agents unless Fulcrum has chosen to accept such materials. Additionally,
if Fulcrum handles, loads, transports or disposes of any Rejected 

  

					
		 	15	 	Confidential

 
Materials (as contemplated by Section 2.7(a)), then under no circumstances shall Fulcrum be deemed an “agent” or “subcontractor” of Supplier for purposes of this
indemnity. 
 (b) Indemnification by Supplier. Supplier shall indemnify, defend and hold harmless Fulcrum and all of
Fulcrum’s Indemnified Parties from and against any and all Losses, which any or all of them may hereafter suffer, incur, be responsible for or pay as a result of: 
 (i) the use, presence or existence of Hazardous Materials at Supplier’s sites; 
 (ii) the use, presence or existence of any materials delivered to the Facility Location by or on behalf of Supplier that constitute Hazardous Materials, or which Fulcrum designates as “Rejected
Materials”; or 
 (iii) the Supplier’s (or its agents) transport of Feedstock, except to the extent caused by
Fulcrum. 
 6.3 Procedure for Indemnification of Third Party Claims. Notwithstanding anything to the contrary contained
in this Agreement: 
 (a) Notice of Claim. If any legal proceedings shall be instituted or any claim or demand shall be
asserted by any third party in respect of which indemnification may be sought by any Indemnified Party under this Article VI, such Indemnified Party shall, within twenty (20) Days of the actual receipt thereof by a responsible
officer, cause written notice of such legal proceedings or the assertion of such claim or demand to be forwarded to the indemnifying Party (the “Indemnitor”), specifying the nature of such legal proceedings, claim or demand and the
amount or the estimated amount thereof to the extent then feasible, which estimate shall not be binding upon the Indemnified Party, in its effort to collect the final amount arising out of such legal proceedings, claim or demand; provided,
that the failure of an Indemnified Party to give timely notice shall not affect its rights to indemnification under this Article VI except to the extent that the Indemnitor has been actually damaged by such failure. 

(b) Conduct of Claim. The Indemnitor shall have the right, at its option and at its own expense, to be represented by counsel of
its choice and to participate in, or take control of, the defense, negotiation and/or settlement of any proceeding, claim or demand that relates to any amounts indemnifiable or potentially indemnifiable under this Article VI;
provided, that the Indemnified Party may participate in any such proceeding with counsel of its choice if (i) the Indemnitor chooses counsel not reasonably acceptable to Indemnified Party, (ii) the Indemnitor does not pursue with
reasonable diligence such defense, negotiation or settlement or (iii) in the reasonable opinion of such Indemnified Party and its counsel, such action, suit or proceeding involves the potential imposition of criminal liability upon such
Indemnified Party or a conflict of interest between such Indemnified Party and the Indemnitor; provided further that, in the case of clause (i), such participation shall be at such Indemnified Party’s own expense and, in the case of
clauses (ii) and (iii), such participation shall be at the Indemnitor’s expense. The Indemnified Party shall have a right to notice of any settlement, and the Indemnitor shall not execute or otherwise agree to any consent decree that
(x) provides for other than monetary payment without the Indemnified Party’s prior written consent, which consent shall not be unreasonably withheld, delayed or conditioned or (y) does not include as an unconditional term thereof the
giving of a release from all liability with respect to such claim by each claimant or plaintiff to each Indemnified Party that is or may be subject to the third party claim, without the Indemnified Party’s prior written consent, which consent
shall not be unreasonably withheld, delayed or 

  

					
		 	16	 	Confidential

 
conditioned. Notwithstanding the foregoing, the Indemnified Party shall have the right to pay or settle any such claim at such Indemnified Party’s own expense; provided, that in such
event it shall waive any right to indemnity therefor by the Indemnitor. If the Indemnitor elects not to defend or settle such proceeding, claim or demand and the Indemnified Party defends, settles or otherwise deals with any such proceeding, claim
or demand directly, the Indemnified Party shall provide fifteen (15) Days advance written notice of any property settlement to the Indemnitor and shall act reasonably and in accordance with the Indemnified Party’s good faith business
judgment. The Indemnitor and the Indemnified Party shall cooperate fully with each other in connection with the defense, negotiation or settlement of any such legal proceeding, claim or demand. 

(c) Payment of Claim. After final judgment or award shall have been rendered by a court, arbitration board or administrative
agency of competent jurisdiction and the expiration of the time in which to appeal therefrom, or a settlement shall have been consummated, or the Indemnified Party and the Indemnitor shall have arrived at a mutually binding agreement with respect to
each separate matter indemnified by the Indemnitor, the Indemnified Party shall forward to the Indemnitor notice of any sums due and owing by the Indemnitor with respect to such matter, and the Indemnitor shall pay all of the sums so owing to the
Indemnified Party by cash in immediately available funds within twenty (20) Days after the date of such notice. 
 (d)
Access to Information. If any claim is made by a third party against an Indemnified Party, the Indemnified Party shall use commercially reasonable efforts to make available to the Indemnitor those partners, members, officers and employees
whose assistance, testimony or presence is necessary to assist the Indemnitor in evaluating and in defending such claims; provided, that any such access shall be conducted in such a manner as not to interfere unreasonably with the operations
of the business of the Indemnified Party, and any reasonable out-of-pocket expenses incurred by any Indemnified Party in connection therewith shall be included in such Indemnified Party’s Losses. 

ARTICLE VII 

UNCONTROLLABLE CIRCUMSTANCES 
 7.1 Excuse of Performance. Each Party shall be excused from performance and shall not be considered to be in default (including Events of Default) with respect to any obligation hereunder, except
the obligation to pay money in a timely manner, if and to the extent that its failure or delay in performance is due to an Uncontrollable Circumstance, provided that: 

(a) Such Party gives the other Party notice describing the particulars of the Uncontrollable Circumstance as soon as is reasonably
practicable; 
 (b) The suspension of performance is of no greater scope and of no longer duration than is reasonably required
by the Uncontrollable Circumstance; 
 (c) The Party uses commercially reasonable efforts to overcome or mitigate the effects
of such Uncontrollable Circumstance; and 
 (d) When the Party is able to resume performance of its obligations under this
Agreement, such Party provides the other Party notice to that effect and promptly resumes performance hereunder. 

  

					
		 	17	 	Confidential

  7.2 Changes to the Feedstock Supply. For the avoidance of any
doubt, and without limiting a Party’s rights under Section 7.1, the Parties acknowledge that in interpreting Section 7.1, Supplier shall be excused from performance and shall not be considered in default (including Events of
Default) with respect to its obligation to deliver Feedstock if, due to reasons outside of the reasonable control of Supplier (by way of example, through loss of franchise or operating agreements or other agreements relating to the collection or
disposal of waste), Supplier is unable (notwithstanding Supplier’s compliance with its obligation to provide first priority to Fulcrum under Section 2.3(a)), to obtain sufficient quantities of Feedstock in the ordinary course of its
business to supply Fulcrum with all of the Feedstock Fulcrum requests hereunder. The foregoing is not intended to limit, and shall not limit, Fulcrum’s rights under Section 4.3. 

ARTICLE VIII 
 DISPUTE RESOLUTION 
 Supplier and Fulcrum shall first attempt in good faith
to resolve any dispute arising out of or in connection with this Agreement or its performance (including the existence and validity of this Agreement) promptly by negotiation between executives who have authority to settle the controversy and who
are at a higher level of management than the persons with direct responsibility for the administration of this Agreement (a “Management Representative”). Within seven (7) Days after determining to invoke dispute resolution, the
Party invoking it shall provide the other Party with a written notice of the dispute, a proposed means for resolving the same, and the support for such position. The second Party shall respond with the same types of information within seven
(7) Days of receiving the first Party’s notice. Thereafter, the Management Representatives of each Party shall meet to discuss the matter and attempt in good faith to reach a negotiated resolution of the dispute. If the Parties have not
agreed upon a resolution of the dispute within twenty (20) Days after the date of the original notice provided under this Article VIII, or such other time period as the Parties may agree in writing to allow for discussions, then either
Party may pursue its rights and remedies under this Agreement and/or under Law. Notwithstanding any provision to the contrary in this Article VIII, nothing herein limits the Parties from immediately seeking injunctive relief or specific
performance with respect to a breach of Section 10.5. Each party submits to the exclusive jurisdiction of the State and Federal courts located in Nevada for all disputes arising out of or relating to this Agreement and waives any right
it might have to claim that those courts are an inconvenient forum.

 10.3 Assignment. 

(a) Generally. This Agreement shall inure to the benefit of and be binding upon the Parties and their respective successors and
permitted assigns. Except as set forth in Section 10.3(b), neither Party shall assign this Agreement or any of its rights hereunder, or delegate any of its obligations hereunder, without the prior written consent of the other Party,
which consent shall not be unreasonably withheld, [***] 
 (b) Right to Assign. Notwithstanding the foregoing, Fulcrum
may, without the prior written consent of Supplier, assign and delegate this Agreement to any Lender. 
 (c) Changes in
Control. A change of control of 50% or more of the capital stock in either Party (except to an Affiliate) shall be deemed an assignment for purposes of Section 10.3(a); provided that the foregoing shall not apply to any direct
or indirect changes in ownership (or to any merger, consolidation, sale of substantially all of the assets, or recombination) of (i) Fulcrum BioEnergy, Inc., in the case of Fulcrum or (ii) Waste Management, Inc., in the case of Supplier
(such entities are herein referred to as the “Ultimate Parent(s)”). [***] 
 (d) Sale of Assets.
Subject to Section 10.3(a) above, in the event that any Party sells or otherwise transfers all or substantially all of its assets to any third party, such Party shall require such third party to assume all of such Party’s
obligations under this Agreement. 
 10.4 Change in Law. Each Party is responsible for continued compliance with Law and
is not relieved of its responsibilities unless a change in Law renders this Agreement as a whole unenforceable or illegal, in which case this Agreement shall terminate without further liability to any Party.

treatment. 

 10.5 Confidentiality. Each Party agrees that, except with the prior written consent
of the other Party, it shall at all times keep confidential and not divulge, furnish or make accessible to anyone any confidential information, knowledge or data concerning or relating to the business or financial affairs of the other Party to which
such Party has been or shall become privy by reason of this Agreement, discussions or negotiations relating to this Agreement, the terms of this Agreement, or the relationship of the Parties contemplated hereby; provided that confidential
information may be disclosed to a Party’s directors, partners, officers, employees, members, managers, advisors, financing sources (including Lenders) or representatives (collectively, the “Representatives”) (provided that
(a) such Representatives shall be informed by such Party of the confidential nature of such information and shall be directed by such Party to keep such information confidential in accordance with the contents of this Agreement and
(b) each Party shall be liable for any breaches of this Section 10.5 by any of its Representatives). The confidentiality obligations of this Section 10.5 do not apply to any information, knowledge or data (i) which
is publicly available or becomes publicly available through no act or omission of the Party wishing to disclose the information, knowledge or data, or (ii) to the extent that it is required to be disclosed by any Law, regulation or legal
process or by the rules of any stock exchange, regulatory body or governmental authority, including in connection with the resolution of any dispute hereunder. The provisions of this Section 10.5 shall survive termination of this
Agreement. 
 10.6 Public Statements. No Party shall be permitted to make any public disclosure (including any press
release) either in writing or orally with respect to this Agreement or the transactions contemplated hereby, or the terms hereof, without the consent of the other Party, which consent shall not be unreasonably withheld. 

10.7 Independent Contractors; No Partnership. Each of Supplier and Fulcrum is, and shall perform this Agreement as, an independent
contractor, and, as such, shall have and maintain complete control over all of its employees, agents and operations. Neither Supplier nor Fulcrum, nor any agent, employee or subcontractor of such Party shall be, represent, act, purport to act or be
deemed to be the agent, representative, employee or servant of the other Party. Nothing contained in this Agreement shall be construed as constituting a joint venture or partnership between Supplier and Fulcrum. 

10.8 Cooperation with Financing. The Parties acknowledge that the Facility may be financed by Financing provided by Lenders. If
Fulcrum assigns this Agreement to the Lenders as collateral to support the Financing, Supplier agrees to enter into an agreement directly with the Lenders under which Supplier shall consent to such assignment and shall agree to other customary and
reasonable provisions for the benefit of the Lenders (including reasonable provisions under which the Lenders or their designees (a) may assume the rights of Fulcrum under this Agreement, (b) shall be entitled to receive copies of certain
notices hereunder relating to defaults and other similar matters that Supplier might provide to Fulcrum, (c) shall have reasonable extended cure periods to cure any defaults by Fulcrum hereunder and (d) shall be provided other similar or
related benefits or protections as reasonably requested by the Lenders and accepted by Supplier to support the Financing), provided that such shall not diminish Supplier’s rights under this Agreement in any way or relieve Fulcrum of its
obligations hereunder. Without limiting the generality of the foregoing, in connection with any collateral assignment by Fulcrum of this Agreement to a Lender as set forth above, Supplier further agrees to furnish the Lenders with such other
documents as may be reasonably requested by the Lenders.

 10.9 Waiver of Consequential Damages. Notwithstanding any other provision in this
Agreement, no Party shall be liable to any other Party for consequential, incidental, punitive, exemplary or indirect damages, including lost profits, or business interruption damages, whether by statute, in tort or in contract, under this
Agreement, or otherwise. 
 10.10 Severability. The invalidity of one or more phrases, sentences, clauses, sections or
articles contained in this Agreement shall not affect the validity of the remaining portions of this Agreement so long as the material purposes of this Agreement can be determined and effectuated. 

10.11 Amendments. No change, amendment or modification of this Agreement shall be valid or binding upon the Parties, unless such
change, amendment or modification shall be in writing and duly executed by both Parties hereto. 
 10.12 Joint Effort.
Preparation of this Agreement has been a joint effort of the Parties and the resulting document shall not be construed more severely against one Party than against the other. 
 10.13 Captions. The captions contained in this Agreement are for convenience and reference only and in no way define, describe, extend or limit the scope or intent of this Agreement or the intent
of any provision contained herein. 
 10.14 Non-Waiver. Any failure of any Party to enforce any of the provisions of this
Agreement or to require compliance with any of its terms at any time during the pendency of this Agreement shall in no way affect the validity of this Agreement, or any part hereof, and shall not be deemed a waiver of the right of such Party
thereafter to enforce any and each such provision. 
 10.15 Counterparts. This Agreement may be signed in any number of
counterparts and each counterpart shall represent a fully executed original as if signed by both Parties. 
 10.16
Survival. The provisions of Section 10.5, and any provision necessary to implement or enforce residual obligations of this Agreement, shall survive the expiration or other termination of this Agreement. 

10.17 Third Parties. Nothing in this Agreement shall be construed to create any duty to, standard of care with respect to, or any
liability to any Person who is not a party to this Agreement. Except for Indemnified Parties with respect to the indemnification obligations hereunder, there are no third party beneficiaries of this Agreement. 

10.18 No Recourse. The obligations of the Parties under this Agreement shall be without recourse to any of the officers, board
members, directors, shareholders, managers, members, employees, agents, partners or Affiliates of such Party, or to the Affiliates of any of the foregoing. 
 10.19 Complete Agreement. This Agreement constitutes the complete agreement between the Parties as of the Effective Date, and supersedes any and all agreements made or dated prior thereto between
the Parties and/or their Affiliates relating to the subject matter hereof.

 10.20 Further Assurances. Each Party hereby covenants and agrees that, at any time
and from time to time it shall, upon the reasonable request of the other, do, execute, acknowledge and deliver or cause to be done, executed, acknowledged and delivered all such further acts, documents and assurances as may be reasonably required
for the carrying out of all the terms of this Agreement. 
 10.21 Costs and Expenses. Each Party shall bear all costs and
expenses (including legal fees) incurred by it in connection with the negotiation and execution of this Agreement. 
  10.22
Green Attributes. As between Supplier and Fulcrum, Supplier shall be entitled to any and all diversion credits arising out of the diversion of Feedstock from landfills, or other Green Attributes related to the collection,
delivery or use of the Feedstock up until the point at which it is delivered to the Facility, and Fulcrum shall be entitled to any and all Green Attributes arising from or relating to the acceptance, processing or use of Feedstock from and after the
point at which it is delivered to the Facility (including the generation of energy from the Feedstock by the Facility), and each Party shall reasonably cooperate with the other in order to maximize each Party’s ability to claim and take
advantage of such diversion credits or other Green Attributes. For purposes hereof, “Green Attributes” means any and all credits, benefits, emissions reductions, offsets and allowances, however entitled, attributable to the
Facility, the collection, delivery or use of Feedstock or the transactions hereunder. 
 The Parties acknowledge their
understanding that, as of the date hereof, Processable Feedstock hereunder is considered “Recyclable Material” under Nevada law (NRS 444A.013) and, therefore, Supplier should be eligible to receive diversion credits under applicable state
or local laws or regulations as a result of the diversion to the Facility of materials that would otherwise go to a landfill. In the event that Supplier’s delivery of Feedstock under this Agreement, for whatever reason, does not qualify as
diversion from landfilling under applicable state or local laws or regulations, then the Parties shall meet and confer in good faith to discuss an amendment to this Agreement which might allow such Feedstock to qualify for diversion credit while
maintaining the original economic position of the Parties hereunder. The Parties also shall reasonably cooperate to support any reasonable lobbying efforts to ensure that such diversion credits are obtainable. 

10.23 Insurance. No later than six (6) months prior to the expected date for the first delivery of Feedstock hereunder, the
Parties shall cooperate to agree upon customary and mutually acceptable insurance requirements applicable to each Party hereunder. 
 10.24 Subcontractors. All contracts between Supplier and any of its subcontractors (including transporters of Feedstock) relating to this Agreement, shall require each such subcontractor to the
extent of the work to be performed by the subcontractor, to be bound to Supplier by the terms of this Agreement, and to assume toward Supplier all the obligations and responsibilities that Supplier, by the terms of this Agreement, assumes toward
Fulcrum. No contractual or other relationship shall exist between Fulcrum and any such subcontractor, subject to the immediately following sentence. Supplier shall be solely responsible for the management of its subcontractors in the performance
under this Agreement and for all work performed hereunder by each such subcontractor. No subcontractor is intended to be or shall be deemed to be a third party beneficiary of this Agreement. Supplier shall promptly pay each subcontractor the amount
to which said subcontractor is entitled.

representatives and other affiliates to keep such information confidential under the same terms as provided herein. Notwithstanding any other provision in this Section 9.15, (i) in the event that such Investor is advised by legal
counsel that disclosure or delivery of information provided by the Company is required by law, legal process, regulation or judicial or administrative order, such Investor may disclose or deliver such information to such authority and (ii) each

 FOURTH AMENDED AND RESTATED RIGHT OF FIRST REFUSAL 

AND CO-SALE AGREEMENT 
 THIS FOURTH AMENDED AND RESTATED RIGHT OF FIRST REFUSAL AND CO-SALE AGREEMENT (this “Agreement”) is dated as of November 16, 2011, by and among (i) Fulcrum BioEnergy,
Inc., a Delaware corporation (the “Company”), (ii) the holders of common stock, par value $0.001 per share, of the Company (the “Common Stock”) and/or options to acquire shares of Common Stock listed on
Schedule A attached hereto, as it may be amended from time to time in accordance with this Agreement (the “Key Holders”), (iii) the holders of the Series A Preferred Stock, par value $0.001 per share, of the
Company (the “Series A Preferred Stock”), listed on Schedule B attached hereto, as it may be amended from time to time in accordance with this Agreement (the “Series A Investors”),
(iv) the holders of the Series B-1 Preferred Stock, par value $0.001 per share, of the Company (the “Series B-1 Preferred Stock”), listed on Schedule C attached hereto, as it may be amended from time to
time in accordance with this Agreement (the “Series B-1 Investors”), (v) the holders of the Series B-2 Preferred Stock, par value $0.001 per share, of the Company (the “Series B-2 Preferred

“Series B-2 Investors” and together with the Series B-1 Investors, the “Series B Investors”), and (vi) the purchasers and the anticipated purchasers of the Series C-1 Preferred Stock, par value $0.001
per share, of the Company (the “Series C-1 Preferred Stock” and, together with the Series A Preferred Stock and the Series B Preferred Stock, the “Preferred Stock”), listed on Schedule E
attached hereto, as it may be amended from time to time in accordance with this Agreement (the “Series C-1 Investors” and together with the Series A Investors and Series B Investors, the “Investors” and,
together with the Key Holders, the “Stockholders”). 
 THE PARTIES ENTER THIS AGREEMENT on the basis of
the following facts, understandings and intentions: 
 A. The Company, the Key Holders, the Series A Investors, the Series B
Investors and certain of the Series C-1 Investors are parties to a Third Amended and Restated Right of First Refusal and Co-Sale Agreement dated as of September 7, 2011 (the “Prior Agreement”). 

B. Concurrently with the execution of this Agreement, the Company and the Series C-1 investors are entering into a Second Amended and
Restated Series C Preferred Stock Purchase Agreement of even date herewith (the “Amended and Restated Purchase Agreement”) and, upon the terms and subject to the conditions of the Amended and Restated Purchase Agreement, the Company
has agreed to issue and sell, and each Series C-1 Investor has agreed to purchase, that number of shares of Series C-1 Preferred Stock set forth opposite its name on Exhibit A or Exhibit B attached thereto, as applicable. 

C. As a condition to the execution of the Amended and Restated Purchase Agreement and as an inducement to such Investors to purchase
shares of Series C-1 Preferred Stock pursuant to the Amended and Restated Purchase Agreement, the Company, the Key Holders and the Investors are entering into this Agreement on the terms and conditions set forth

 
below to provide the Company and the Investors with certain rights of first refusal and co-sale rights upon any Proposed Transfer (as defined below) of Transfer Stock (as defined below) as set
forth below. 
 D. The Company, the Key Holders, the Series A Investors, the Series B Investors and the current Series C-1
Investors desire to induce additional Series C-1 Investors to purchase shares of Series C-1 Preferred Stock pursuant to the Amended and Restated Purchase Agreement by agreeing to the terms and conditions set forth below. 

E. The Company and the Stockholders desire to amend and restate the Prior Agreement in its entirety as set forth herein. 

NOW THEREFORE, in consideration of the foregoing premises and certain other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereby agree as follows: 
 A. Amendment of Prior
Agreement. 
 Pursuant to Section 6.5 of the Prior Agreement, effective and contingent upon execution of this
Agreement by the Company and the holders of eighty percent (80%) of (i) the shares of capital stock held by the Investors (as defined in the Prior Agreement) and (ii) the shares of Preferred Stock remaining to be purchased under the
Amended and Restated Purchase Agreement, dated as of September 7, 2011 (the “Purchase Agreement”), including the approval of the holders of a majority of the Series C-1 Preferred Stock that was to be purchased under the
Purchase Agreement, the Prior Agreement is hereby amended and restated in its entirety to read as set forth in this Agreement, and the Company and the Stockholders shall be bound by the provisions hereof as the sole agreement of the Company and the
Stockholders with respect to the subject matter hereof. 
 1. Agreement Among the Company, the Investors and the Key
Holders. 
 1.1 Right of First Refusal. In the event any Stockholder proposes to assign, sell, offer to sell,
pledge, mortgage, hypothecate, encumber, dispose of or otherwise transfer (a “Proposed Transfer”) any shares of capital stock of the Company now owned or hereafter acquired by the Stockholders (“Transfer Stock”),
such Stockholder shall deliver a written notice (a “Proposed Transfer Notice”) to the Company and each Investor setting forth the material terms and conditions (including price and form of consideration) of such Proposed Transfer
and the identity of the Person (as defined below) to whom such Stockholder proposes to make a Proposed Transfer (the “Prospective Transferee”) not later than forty-five (45) days prior to the consummation of such Proposed
Transfer. For purposes of this Agreement, the term “Person” shall mean an individual, firm, corporation, partnership, association, limited liability company, trust or any other entity. 

(a) Grant of Right of First Refusal to the Company. Subject to the terms of Section 2 below, each Stockholder hereby
unconditionally and irrevocably grants to the Company the right, but not the obligation, to purchase all or any portion of the shares of Transfer Stock at the same price and on the same terms and conditions as those offered to the Prospective
Transferee in the Proposed Transfer. To exercise its right of first refusal under this Section  

  
 2 

 
1.1(a), the Company must deliver a written notice to the selling Stockholder within fifteen (15) days after delivery of the Proposed Transfer Notice. 

(b) Grant of Secondary Refusal Right to Investors. If the Company does not intend to purchase all of the Transfer Stock subject to
a Proposed Transfer, the Company must deliver a written notice to the selling Stockholder and to each Investor to that effect (a “Secondary Notice”) no later than fifteen (15) days after delivery of the Proposed Transfer Notice
to the Company. Subject to the terms of Section 2 below, each Stockholder hereby unconditionally and irrevocably grants to each of the Investors the right, but not the obligation, to purchase up to its pro rata portion (based upon the
total number of shares of capital stock of the Company then held by all Investors on an as converted basis) of any Transfer Stock not purchased by the Company pursuant to Section 1.1(a) above. To exercise its secondary refusal right
pursuant to this Section 1.1(b), an Investor must deliver a written notice to the selling Stockholder and the Company (an “Investor Notice”) within ten (10) days after the expiration of the Company’s right of
first refusal pursuant to Section 1.1(a) above (the “Investor Notice Period”). 
 (c)
Undersubscription of Transfer Stock. If the rights of first refusal and secondary refusal rights of the Company and the Investors, respectively, have been exercised with respect to some but not all of the Transfer Stock by the end of the
Investor Notice Period, then the Company shall, immediately after the expiration of the Investor Notice Period, send written notice (the “Company Undersubscription Notice”) to those Investors who fully exercised their secondary
refusal right under Section 1.1(b) above within the Investor Notice Period (the “Exercising Investors”). Each Exercising Investor shall, subject to the provisions of this Section 1.1(c), have an additional
right to purchase all or any part of the balance of any such remaining unsubscribed shares of Transfer Stock on the terms and conditions set forth in the Proposed Transfer Notice. To exercise such right, an Exercising Investor must deliver written
notice to the Company and the selling Stockholder that such Exercising Investor intends to exercise such right (an “Undersubscription Notice”) within ten (10) days after the expiration of the Investor Notice Period. In the
event there are two (2) or more such Exercising Investors that choose to exercise such right, the remaining shares available for purchase under this Section 1.1(c) shall be allocated to such Exercising Investors pro rata based on
the number of shares of Transfer Stock such Exercising Investors have elected to purchase pursuant to their secondary refusal right under Section 1.1(b) above (without giving effect to any shares of Transfer Stock that any such
Exercising Investor has elected to purchase pursuant to the Company Undersubscription Notice). If the Exercising Investors elect to purchase all remaining unsubscribed shares pursuant to this Section 1.1(c), the Company shall immediately
notify all of the Exercising Investors and the selling Stockholder of that fact. 
 (d) Forfeiture of Rights.
Notwithstanding the foregoing, if the total number of shares of Transfer Stock that the Company and the Investors have agreed to purchase in the Company Notice, Investor Notices and Undersubscription Notices is less than the total number of shares
of Transfer Stock, then the Company and the Investors shall be deemed to have forfeited any right to purchase such Transfer Stock, and the selling Stockholder shall be free to sell all, but not less than all, of the Transfer Stock to the Prospective
Transferee on terms and conditions substantially similar to (and in no event more favorable than) the terms and conditions set forth in the Proposed Transfer Notice, it being understood and agreed that (i) any such sale or

  
 3 

 
transfer shall be subject to the other terms and restrictions of this Agreement, including without limitation the terms and restrictions set forth in Sections 1.2 and 6.8(b);
(ii) any future Proposed Transfer shall remain subject to the terms and conditions of this Agreement, including this Section 1.1; and (iii) such sale shall be consummated within forty-five (45) days after receipt of the
Proposed Transfer Notice by the Company and, if such sale is not consummated within such forty-five (45) day period, such sale shall again become subject to the Company’s and the Investors’ refusal rights set forth in this
Section 1.1. 
 (e) Consideration; Closing. If the consideration proposed to be paid for the Transfer Stock
is in property, services or other non-cash consideration, the fair market value of the consideration shall be as determined in good faith by the Company’s Board of Directors and as set forth in the Company Notice. If the Company or any Investor
cannot for any reason pay for the Transfer Stock in the same form of non-cash consideration, the Company or such Investor may pay the cash value equivalent thereof, as determined in good faith by the Board of Directors and as set forth in the
Company Notice. The closing of the purchase of Transfer Stock by the Company and the Investors shall take place, and all payments from the Company and the Investors shall have been delivered to the selling Stockholder, by the later of (i) the
date specified in the Proposed Transfer Notice as the intended date of the Proposed Transfer and (ii) forty-five (45) days after delivery of the Proposed Transfer Notice. 

1.2 Right of Co-Sale. 
 (a) Exercise of Right. If the Transfer Stock subject to a Proposed Transfer is not purchased by the Company and/or the Investors pursuant to Section 1.1 above and thereafter is to be
sold to a Prospective Transferee, each respective Investor may elect to exercise its right, but not obligation, to participate on a pro rata basis in the Proposed Transfer as set forth in Section 1.2(b) below and otherwise on the same
terms and conditions specified in the Proposed Transfer Notice (provided that if the Proposed Transfer contemplated the sale of Common Stock and an Investor wishes to sell Preferred Stock, the price set forth in the Proposed Transfer Notice shall be
appropriately adjusted based on the conversion ratio of the Preferred Stock into Common Stock). Each Investor who desires to participate in the Proposed Transfer pursuant to this Section 1.2(a) must give the selling Stockholder written
notice to that effect within fifteen (15) days after the deadline for delivery of the Secondary Notice described above. 

(b) Shares Includable. Each Investor who timely exercises its right to participate in the Proposed Transfer by delivering the
written notice described in Section 1.2(a) above may include in such Proposed Transfer the portion of such Investor’s shares of Common Stock or Preferred Stock, as appropriate, equal to the product obtained by multiplying
(i) the aggregate number of shares of Transfer Stock on an as-converted basis subject to the Proposed Transfer by (ii) a fraction, (x) the numerator of which is the number of shares of Common Stock owned by such Investor on an
as-converted basis immediately before consummation of the Proposed Transfer and (y) the denominator of which is the total number of shares of Common Stock owned, in the aggregate, by all Investors on an as-converted basis immediately prior to
the consummation of the Proposed Transfer, plus the number of shares of Transfer Stock held by the selling Stockholder (if such selling Stockholder is not an Investor). To the extent one or more of the Investors exercise such right of participation
in accordance with the terms and conditions set 

  
 4 

 
forth herein, the number of shares of Transfer Stock on an as-converted basis that the selling Stockholder may sell in the Proposed Transfer shall be correspondingly reduced. 

(c) Purchase Agreement. The parties hereby agree that the terms and conditions of any sale pursuant to this
Section 1.2 will be memorialized in, and governed by, a written purchase and sale agreement with customary terms and provisions for such a transaction and the parties further covenant and agree to enter into such an agreement as a
condition precedent to any sale or other transfer pursuant to this Section 1.2. If any Prospective Transferee or Transferees refuse(s) to purchase securities from any Investor exercising its co-sale rights pursuant to this
Section 1.2, no Stockholder may sell any Transfer Stock to such Prospective Transferee or Transferees unless and until, simultaneously with such sale, such Stockholder purchases all securities from such Investor on the same terms and
conditions (including the proposed purchase price) as set forth in the Proposed Transfer Notice. 
 (d) Additional
Compliance. If any Proposed Transfer is not consummated within forty-five (45) days after receipt of the Proposed Transfer Notice by the Company, the selling Stockholder proposing the Proposed Transfer may not sell any Transfer Stock unless
they first comply in full with each provision of this Section 1. The exercise or election not to exercise any right by any Investor hereunder shall not adversely affect its right to participate in any other sales of Transfer Stock
subject to this Section 1. 
 1.3 Effect of Failure to Comply. 

(a) Transfer Void; Equitable Relief. Any Proposed Transfer not made in compliance with the requirements of this Agreement shall be
null and void ab initio, shall not be recorded on the books of the Company or its transfer agent and shall not be recognized by the Company. Each party hereto acknowledges and agrees that any breach of this Agreement would result in
substantial harm to the other parties hereto for which monetary damages alone could not adequately compensate. Therefore, the parties hereto unconditionally and irrevocably agree that any non-breaching party hereto shall be entitled to seek
protective orders, injunctive relief and other remedies available at law or in equity (including, without limitation, seeking specific performance or the rescission of purchases, sales and other transfers of Transfer Stock not made in strict
compliance with this Agreement). 
 (b) Violation of First Refusal Right. If any Stockholder becomes obligated to sell
any Transfer Stock to the Company or any Investor under this Agreement and fails to deliver such Transfer Stock in accordance with the terms of this Agreement, the Company and/or such Investor may, at its option, in addition to all other remedies it
may have, send to such Stockholder the purchase price for such Transfer Stock as is herein specified and transfer to the name of the Company or such Investor (or request that the Company effect such transfer in the name of an Investor) on the
Company’s books the certificate or certificates representing the Transfer Stock to be sold. 
 (c) Violation of Co-Sale
Right. If any Stockholder purports to sell any Transfer Stock in contravention of the Investors’ co-sale rights under Section 1.2 above (a “Prohibited Transfer”), each Investor that exercises its rights under
such Section 1.2 may, in addition to such remedies as may be available by law, in equity or hereunder, require such 

  
 5 

 
Stockholder to purchase from such Investor the type and number of shares of capital stock that such Investor would have been entitled to sell to the Prospective Transferee under
Section 1.2 had the Prohibited Transfer been effected pursuant to and in compliance with the terms of Section 1.2. The sale will be made on the same terms and subject to the same conditions as would have applied had the
Stockholder not made the Prohibited Transfer, except that the sale (including, without limitation, the delivery of the purchase price) must be made within ninety (90) days after the Investor learns of the Prohibited Transfer (instead of the
forty-five (45)-day period set forth in Section 1.2). Such Stockholder shall also reimburse each Investor for any and all reasonable and documented out-of-pocket fees and expenses, including reasonable legal fees and expenses, incurred
pursuant to the exercise or the attempted exercise of the Investor’s rights under Section 1.2. 
 2.
Exempt Transfers. 
 2.1 Exempted Transfers. Notwithstanding the foregoing or anything to the contrary herein,
the provisions of Sections 1.1 and 1.2 shall not apply: (a) to a transfer by a Stockholder to one or more Persons who, directly or indirectly, control, are controlled by or are under common control with such Persons, including,
without limitation, any general partner, managing member, officer or director of such Persons or any investment fund now or hereafter existing that is controlled by one or more general partners or managing members of, or shares the same management
company with, such Persons (each an “Affiliate” and collectively, “Affiliates”), (b) to acquisitions of Transfer Stock from a Stockholder by this Corporation pursuant to agreements which permit this Corporation
to repurchase such shares upon termination of services to this Corporation or (c) in the case of a Stockholder that is a natural person, upon a transfer of Transfer Stock by such Stockholder made for bona fide estate planning purposes, either
during his or her lifetime or on death by will or intestacy to his or her spouse, child (natural or adopted), or any other direct lineal descendant of such Stockholder (or his or her spouse) (all of the foregoing collectively referred to as
“family members”), or any other relative/person approved by the Board of Directors of the Company, or any custodian or trustee of any trust, partnership or limited liability company for the benefit of, or the ownership interests of which
are owned wholly by, such Stockholder or any such family members; provided that in the case of clause(s) (a) or (c), the Stockholder shall deliver prior written notice to the other Stockholders of such pledge, gift or transfer and
such shares of Transfer Stock shall at all times remain subject to the terms and restrictions set forth in this Agreement and such transferee shall, as a condition to such issuance, execute and deliver an Adoption Agreement substantially in the form
attached hereto as Exhibit A (the “Adoption Agreement”); and provided further, in the case of any transfer pursuant to clause (a) or (c) above, that such transfer is made pursuant to a transaction
in which there is no consideration actually paid for such transfer. 
 2.2 Exempted Offerings. Notwithstanding the
foregoing or anything to the contrary herein, the provisions of Section 1 shall not apply to the sale of any Transfer Stock (a) in a Qualified IPO (as such term is defined in the Certificate of Incorporation of the Company, as
amended (the “Charter”)), or (b) pursuant to a Change of Control (as defined in the Charter). 

  
 6 

 3. Legends. 

3.1 In addition to any other legends required, each certificate representing shares of Transfer Stock held by the Stockholders or issued
to any permitted transferee in connection with a transfer permitted by Section 2 which is subject to the restrictions of this Agreement shall be endorsed with the following restrictive legend (the “Legend”): 

“THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO, AND IN CERTAIN CASES
PROHIBITED BY, THE TERMS AND CONDITIONS OF A CERTAIN RIGHT OF FIRST REFUSAL AND CO-SALE AGREEMENT BY AND AMONG THE STOCKHOLDER, THE CORPORATION AND CERTAIN OTHER HOLDERS OF STOCK OF THE CORPORATION. A COPY OF SUCH RIGHT OF FIRST REFUSAL AND CO-SALE
AGREEMENT WILL BE FURNISHED TO THE RECORD HOLDER OF THIS CERTIFICATE WITHOUT CHARGE UPON WRITTEN REQUEST TO THE CORPORATION AT ITS PRINCIPAL PLACE OF BUSINESS.” 
 3.2 Each Stockholder agrees that the Company may instruct its transfer agent to impose transfer restrictions on the shares represented by certificates bearing the Legend to enforce the provisions of this
Agreement. The Company, by its execution of this Agreement, agrees that, during the term of this Agreement, it will maintain (upon registration of transfer, reissuance or otherwise) the Legend on any such certificate and will place or cause to be
placed the Legend on any new certificate issued to represent shares of Transfer Stock previously represented by a certificate carrying the Legend, and will supply, free of charge, a copy of this Agreement to any holder of a certificate evidencing
shares of Transfer Stock upon written request from such holder to the Company at its principal office. The parties hereto do hereby agree that the failure by the Company to cause the certificates evidencing such shares to bear the Legend and/or the
failure to supply, free of charge, a copy of this Agreement shall not affect the validity or enforcement of this Agreement. 

4. “Market Stand-Off” Agreement. 
 4.1 “Market Stand-Off”. 
 (a) Each Key Holder hereby agrees that,
during the period of duration (not to exceed one hundred eighty (180) days) specified by the Company and an underwriter of Common Stock or other securities of the Company following the effective date of the registration statement for a
Qualified IPO, it shall not, to the extent requested by the Company and such underwriter, directly or indirectly sell, offer to sell, contract to sell (including, without limitation, any short sale), grant any option to purchase, pledge or otherwise
transfer or dispose of (other than to donees who agree to be similarly bound) any Registrable Securities of the Company held by it at any time during such period except common stock included in such registration; provided however that, if during the
last 17 days of the restricted period the Company issues an earnings release or material news or a material event relating to the Company occurs, or prior to the expiration of the restricted period the Company announces that it will release earnings
results during the 16-day period beginning on the last day of the restricted period, then, upon the request 

  
 7 

 
of the managing underwriter, to the extent required by any FINRA rules, the restrictions imposed by this subsection (a) shall continue to apply until the end of the third trading day
following the expiration of the 15-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event. In no event will the restricted period extend beyond 216 days after the effective date of the
registration statement. The term “Registrable Securities” means (i) shares of Common Stock issued or issuable upon conversion of shares of Preferred Stock; and (ii) any and all stock issued with respect to (as a dividend
or distribution or otherwise) or in any exchange for or in replacement of any of the shares referred to in subsection (i) hereof; provided, however, that Registrable Securities shall not include any securities of the Company which
have been previously registered and sold or which have been sold to the public either pursuant to a registration statement or Rule 144. 
 (b) The obligations described in Section 4.1(a) shall not be required unless all officers and directors who hold shares of the Company as well as all stockholders of the Company holding more
than one percent (1%) of the outstanding shares of Common Stock (after giving effect to the conversion into Common Stock of all outstanding Preferred Stock) enter into similar agreements. The underwriters in connection with the Qualified IPO
are intended third party beneficiaries of this Section 4 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. Each Keyholder further agrees to execute such agreements as may
be reasonably requested by the underwriters in the Qualified IPO that are consistent with this Section 4 or that are necessary to give further effect thereto. 
 4.2 Stop Transfer Instructions. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to the shares of Capital Stock of each Stockholder (and
transferees and assignees thereof) until the end of such restricted period. 
 5. Termination. 

5.1 Termination Events. This Agreement shall terminate and have no further force and effect upon the earlier of (a) the
closing of a Qualified IPO, (b) the closing of a Change of Control or (c) the date as of which the Company and the Investors terminate this Agreement by the written consent of the Company and the holders of at least eighty percent
(80%) of the shares of capital stock of the Company held by the Investors, voting together as a single class on an as-converted basis. Notwithstanding the foregoing, Sections 4.1 and Section 5.2 shall survive termination of
this Agreement. 
 5.2 Removal of Legend. At any time after the termination of this Agreement in accordance with
Section 5.1 hereto, any holder of a stock certificate bearing the Legend may surrender such certificate to the Company for removal of the legend, and the Company will duly reissue a new certificate without the legend. 

6. Miscellaneous. 
 6.1 Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith. In the event that the
parties cannot reach a mutually agreeable and enforceable replacement for 

  
 8 

 
such provision, then (a) such provision shall be excluded from this Agreement, (b) the balance of this Agreement shall be interpreted as if such provision were so excluded and
(c) the balance of this Agreement shall be enforceable in accordance with its terms. 
 6.2 Entire Agreement. This
Agreement and the Exhibits hereto, along with the Amended and Restated Purchase Agreement and the other documents delivered pursuant thereto, constitute the full and entire understanding and agreement between the parties with regard to the subjects
hereof and thereof and no party shall be liable or bound to any other in any manner by any oral or written representations, warranties, covenants or agreements except as specifically set forth herein and therein. Each party expressly represents and
warrants that it is not relying on any oral or written representations, warranties, covenants or agreements outside of this Agreement. 
 6.3 Notices. All notices and other communications required or permitted hereunder shall be in writing and shall be mailed by registered or certified mail, postage prepaid, or otherwise delivered by
hand or by messenger, addressed (a) if to a Key Holder, at such Key Holder’s respective address set forth on Schedule A attached hereto, or at such other address as such Key Holder shall have properly furnished in writing to
the Company, (b) if to an Investor, at such Investor’s respective address set forth on Schedule B, Schedule C, Schedule D or Schedule E attached hereto attached hereto, as applicable, or at such other
address as such Investor shall have properly furnished in writing to the Company, or (c) if to the Company, at 4900 Hopyard Road, Suite 220, Pleasanton, CA 94588, Fax: (925) 730-0157, Attn: Corporate Secretary, or at such other address as
the Company shall have properly furnished to the Key Holders and the Investors in writing. Such notices shall be deemed effective upon (i) personal delivery to the party to be notified; (ii) when sent by confirmed electronic mail or
facsimile if sent during normal business hours of the recipient; if not, then on the next business day; (iii) one (1) business day after deposit with a nationally recognized overnight carrier, specifying next day delivery; or
(iv) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid. 

6.4 Governing Law. This Agreement shall be governed in all respects by the laws of the State of Delaware without regard to the
conflict of laws provisions. The parties hereto agree to submit to the exclusive jurisdiction of the federal and state courts of the State of Delaware with respect to the interpretation of this Agreement or for the purposes of any action arising out
of or relating to this Agreement. 
 6.5 Amendment or Waiver. This Agreement may be amended or modified (or provisions of
this Agreement waived) only upon the written consent of (i) the Company and (ii) the holders of at least eighty percent (80%) of the shares of capital stock of the Company held by the Investors, voting together as a single class on an
as-converted basis; provided that, the Company may amend Schedule A, Schedule B, Schedule C, Schedule D, and/or Schedule E attached hereto from time to time to add information regarding
(A) additional Key Holders or Investors, as applicable, that have executed and delivered Adoption Agreements, or (B) additional Shares acquired by the Key Holders or the Investors after the date hereof, without the consent of the other
parties hereto. Any amendment or waiver so effected shall be binding upon the Company, each of the parties hereto and any assignee of any such party. Notwithstanding anything to the contrary herein, this Agreement may not be amended or waived with
respect to 

  
 9 

 
any Investor without the written consent of such Investor unless such amendment or waiver applies to all Investors in the same fashion. 

6.6 Additional Key Holders. In the event that after the date of this Agreement, the Company issues to any Person shares of its
capital stock, or options to purchase its capital stock, that represent 1% or more of the Company’s fully diluted capitalization, the Company shall, as a condition to such issuance, cause such Person to execute and deliver an Adoption
Agreement, and such person shall thereby be bound by, and subject to, all the terms and provisions of this Agreement applicable to a Key Holder. 
 6.7 Assignment of Rights. 
 (a) The terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the respective successors and permitted assigns of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective
successors and permitted assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. 
 (b) Any successor or permitted assignee of any Stockholder, including any Prospective Transferee who purchases shares of Transfer Stock in accordance with the terms hereof, shall execute and deliver, as a
condition to any transfer or assignment, an Adoption Agreement. Upon the execution and delivery of an Adoption Agreement by any such successor or permitted assignee, such successor or permitted assignee shall become a party to this Agreement and
shall be bound by all of the provisions hereof as if such person were a Key Holder or Investor, as applicable, and such successor or permitted assignee’s signature appeared on the signature pages to this Agreement. 

(c) Except in connection with an assignment by the Company by operation of law to the acquirer of the Company, the rights and obligations
of the Company hereunder may not be assigned under any circumstances. 
 6.8 Delays or Omissions. No delay or omission to
exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this Agreement shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach,
default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring. Any waiver, permit, consent or approval of any kind or character on any party’s part of any breach, default or
noncompliance under this Agreement or any waiver on such party’s part of any provisions or conditions of the Agreement must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either
under this Agreement by law, or otherwise afforded to any party, shall be cumulative and not alternative. 
 6.9
Attorney’s Fees. If any suit or action is instituted under or in relation to this Agreement, the prevailing party in such dispute shall be entitled to recover from the losing party all fees, costs and expenses of such suit or action
(including any appeals), including without limitation, the reasonable fees and expenses of attorneys and accountants. 

  
 10 

 6.10 Counterparts. This Agreement may be executed in any number of counterparts, each
of which shall be an original, and all of which together shall constitute one instrument. 
 6.11 Titles and Subtitles.
The titles and subtitles of the Sections of this Agreement are for convenience of reference only and are not to be considered in construing or interpreting this Agreement. 
 6.12 Consent of Spouse. If any individual Stockholder is married on the date of this Agreement, such owned by the Stockholder’s spouse shall execute and deliver to the Company a consent of
spouse in the form of Exhibit B hereto (“Consent of Spouse”), effective on the date hereof. Notwithstanding the execution and delivery thereof, such consent shall not be deemed to confer or convey to the spouse any
rights in such owned by such Stockholder’s shares of Transfer Stock that do not otherwise exist by operation of law or the agreement of the parties. If any individual Stockholder should marry or remarry subsequent to the date of this Agreement,
such owned by the Stockholder shall within thirty (30) days thereafter obtain his/her new spouse’s acknowledgement of and consent to the existence and binding effect of all restrictions contained in this Agreement by causing such spouse to
execute and deliver a Consent of Spouse acknowledging the restrictions and obligations contained in this Agreement and agreeing and consenting to the same.

 EXHIBIT A 

ADOPTION AGREEMENT 
 THIS ADOPTION AGREEMENT (this “Adoption Agreement”) is executed by the undersigned (the “Holder”) pursuant to the terms of that certain Fourth Amended and Restated
Right of First Refusal and Co-Sale Agreement dated as of November 16, 2011 (the “Agreement”), by and among the Company, the Key Holders listed on Schedule A attached thereto, the Series A Investors listed on
Schedule B attached thereto, the Series B-1 Investors listed on Schedule C attached thereto, the Series B-2 Investors listed on Schedule D attached thereto and the Series C-1 Investors listed on
Schedule E attached thereto. Capitalized terms used but not defined herein shall have the respective meanings ascribed to such terms in the Agreement. By the execution of this Adoption Agreement, the Holder agrees as follows: 

1.1 Acknowledgement. Holder acknowledges that Holder is acquiring certain shares of Capital Stock (including any options, warrants
or other rights to purchase such Capital Stock), for one of the following reasons (check the correct box): 
  

	 	 ̈	as a transferee of shares of Capital Stock from a party in such party’s capacity as an “Investor” bound by the Agreement, and after such transfer, Holder
shall be considered an “Investor” and a “Stockholder” for all purposes of the Agreement. 

  

	 	 ̈	as a transferee of shares of Capital Stock from a party in such party’s capacity as a “Key Holder” bound by the Agreement, and after such transfer,
Holder shall be considered a “Key Holder” and a “Stockholder” for all purposes of the Agreement. 

  

	 	 ̈	in accordance with Section 6.5 and/or Section 6.6 of the Agreement, as a new “Key Holder,” in which case Holder will be a “Key
Holder” and “Stockholder” for all purposes of the Agreement, or as a new “Investor,” in which case Holder will be an “Investor” and a “Stockholder” for all purposes of the Agreement.

 1.2 Agreement. Holder hereby (a) agrees that the shares of Capital Stock and any other securities
required by the Agreement to be bound thereby, shall be bound by and subject to the terms of the Agreement and (b) adopts the Agreement with the same force and effect as if Holder were originally a party thereto. 

1.3 Notice. Any notice required or permitted by the Agreement shall be given to Holder at the address, facsimile number or email
listed below Holder’s signature hereto.

spouse of                             , acknowledge that I have read the Fourth Amended and Restated
Right of First Refusal and Co-Sale Agreement, dated as of November 16, 2011, to which this Consent is attached as Exhibit B (the “Agreement”), and that I know the contents of the Agreement. I am aware that the
Agreement contains provisions regarding certain rights to certain other holders of Capital Stock of the Company upon a Proposed Transfer of shares of Transfer Stock of the Company which my spouse may own including any interest I might have therein.

 I hereby agree that my interest, if any, in any shares of Transfer Stock of the Company subject to the Agreement shall be

I am aware that the legal, financial and related matters contained in the Agreement are complex and that I am free to seek independent
professional guidance or counsel with respect to this Consent. I have either sought such guidance or counsel or determined after reviewing the Agreement carefully that I will waive such right.

 D. The Company, the Key Holders, the Series A Investors, the Series B Investors and current

E. The Company and the Key Holders and the Investors (collectively, the “Stockholders”) desire to amend and restate the
Prior Agreement in its entirety as set forth herein. 
 NOW THEREFORE, in consideration of the foregoing premises and
certain other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereby agree as follows: 
 A. Amendment of Prior Agreement. 
 Pursuant to Section 4.6 of
the Prior Agreement, effective and contingent upon execution of this Agreement by the Company and the holders of eighty percent (80%) of (i) the Investor Shares (as defined in the Prior Agreement) and (ii) the shares of Preferred
Stock remaining to be purchased under the Amended and Restated Purchase Agreement, dated as of September 7, 2011 (the “Purchase Agreement”), including the approval of the holders of a majority of the Series C-1 Preferred Stock
that was to be purchased under the Purchase Agreement by the New Investors (as defined in the Purchase Agreement), the Prior Agreement is hereby amended and restated in its entirety to read as set forth in this Agreement, and the Company and the
Stockholders shall be bound by the provisions hereof as the sole agreement of the Company and the Stockholders with respect to the subject matter hereof. 
 1. Voting. 
 1.1 Key Holders; Investor Shares. 

(a) Key Holders. Each Key Holder hereby agrees to hold all shares of voting capital stock of the Company registered in its name or
beneficially owned by it as of the date hereof, if any, and any and all other securities of the Company legally or beneficially acquired by such Key Holder after the date hereof (collectively, the “Key Holder Shares”) subject to,
and to vote the Key Holder Shares at each regular and each special meeting of stockholders (whether by written consent or otherwise) in accordance with, the provisions of this Agreement. 

(b) Investors. Each Investor hereby agrees to hold all shares of voting capital stock of the Company registered in its name or

Agreement. 
 1.2 Election of Directors. On all matters relating to the election of directors of the Company, the Key
Holders and the Investors agree to vote all Shares held by them (or to

“Board of Directors”) as follows:

 (b) two (2) individuals designated jointly by Rustic Canyon Ventures SBIC, LP and
Rustic Canyon Ventures III, L.P. (collectively, “RCV”), so long as they collectively hold any shares of Series B Preferred Stock (as adjusted for any stock dividends, combinations, splits, recapitalizations and the like
affecting such shares), which individuals initially shall be Tom Unterman and Nate Redmond; 
 (c) one (1) individual
designated by USRG Holdco 3D, LLC (“USRG Holdco 3D”), so long as it holds any shares of Series C-1 Preferred Stock (as adjusted for any stock dividends, combinations, splits, recapitalizations and the like affecting such shares),
which individual initially shall be Jonathan Koch; 
 (d) the individual serving as Chief Executive Officer of the Company; and

 (e) in the event (i) the Board of Directors fail to reach agreement as a result of a vote deadlocked at 3-3, or

(1) individual designated by USRG Holdco 3D to serve as a member of the Board of Directors until such time as the deadlocked vote is resolved or the Company’s expenditures are less than a ten percent (10%) variance from the
Company’s approved annual budget, as applicable, or until such earlier time as agreed upon by the holders of at least a majority of the outstanding shares of Series C-1 Preferred Stock, voting as a separate class on an as-converted basis,
which vote must include the approval of USRG Holdco 3D. USRG Holdco 3D shall have the right to designate a member of the Board of Directors pursuant to this Section 1.2(e) in each instance a Board Event occurs. 

1.3 Removal. USRG HOLDCO, RCV and USRG Holdco 3D, as applicable, may remove its designated director(s) at any time and from time to
time, with or without cause (subject to the Bylaws of the Company as in effect from time to time and any requirements of law), in their respective sole discretion, and after written notice to each of the parties hereto of the new nominee(s) to
replace such director(s) and, with respect to a nominee of USRG HOLDCO, RCV or USRG Holdco 3D, as applicable, each Investor shall promptly vote its Investor Shares to remove or elect, as applicable, such nominee(s) to the Board of Directors pursuant
to Sections 1.2(a), 1.2(b), 1.2(c) and 1.2(e), respectively. 
 1.4 Directors and Officers
Liability Insurance. The Company shall obtain and keep directors and officers liability insurance (including “Side A” and “Side B” coverage) in the minimum amount of $5,000,000, so long as any representative(s) of the
Investors serve on the 

  
 3 

 
Board, unless and until such coverage is unavailable on commercially reasonable terms as determined by the Board of Directors. 

2. Additional Representations and Covenants. 
 2.1 Covenants of the Company. The Company agrees to use its best efforts to ensure that the rights granted under this Agreement are effective and that the parties hereto enjoy the benefits thereof.
Such actions include, without limitation, the use of the Company’s best efforts to cause its representatives to prepare and distribute the documents and obtain the approvals and consents necessary to effectuate the transactions described in
this Agreement. The Company shall not, by any voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be performed hereunder by the Company, but shall at all times in good faith assist in the carrying out of all
of the provisions of this Agreement and in the taking of all such actions as may be necessary, appropriate or reasonably requested by the applicable party. The Company shall use its best efforts to cause any individual, firm, corporation,
partnership, association, limited liability company, trust or any other entity (collectively, a “Person”) who, after the date of this Agreement, (i) becomes the beneficial holder of Common Stock or otherwise acquires an
interest in or right to acquire Common Stock (including, without limitation, options, warrants or other securities convertible into, exchangeable or exercisable for shares of Common Stock), or (ii) acquires any shares of any other class or
series of capital stock of the Company or any options, warrants or other securities convertible, exchangeable or exercisable into such other class or series of capital stock of the Company, in each case, that represent 1% or more of the
Company’s fully diluted capitalization, to agree to be bound by the terms of this Agreement and execute and deliver an Adoption Agreement substantially in the form attached hereto as Exhibit A (the “Adoption
Agreement”). 
 2.2 No Revocation. The agreements contained herein are coupled with an interest and may not be
revoked during the term of this Agreement except as provided in this Agreement. 
 2.3 Legends. 

(a) Each certificate representing the Shares shall be endorsed by the Company with the following restrictive legend (the
“Legend”): 
 “THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND CONDITIONS OF A
VOTING AGREEMENT WHICH PLACES CERTAIN RESTRICTIONS ON THE VOTING OF THE SHARES REPRESENTED HEREBY. ANY PERSON ACCEPTING ANY INTEREST IN SUCH SHARES SHALL BE DEEMED TO AGREE TO AND SHALL BECOME BOUND BY ALL THE PROVISIONS OF SUCH AGREEMENT. A COPY OF
SUCH VOTING AGREEMENT WILL BE FURNISHED TO THE RECORD HOLDER OF THIS CERTIFICATE WITHOUT CHARGE UPON WRITTEN REQUEST TO THE CORPORATION AT ITS PRINCIPAL PLACE OF BUSINESS.” 

(b) The Company, by its execution of this Agreement, agrees that, during the term of this Agreement, it will maintain (upon registration
of transfer, reissuance or 

  
 4 

 
otherwise) the Legend on any such certificate and will place or cause to be placed the Legend on any new certificate issued to represent Shares previously represented by a certificate carrying
the Legend, and will supply, free of charge, a copy of this Agreement to any holder of a certificate evidencing Shares upon written request from such holder to the Company at its principal office. The parties hereto do hereby agree that the failure
by the Company to cause the certificates evidencing such shares to bear the Legend and/or the failure to supply, free of charge, a copy of this Agreement shall not affect the validity or enforcement of this Agreement. The Legend shall be removed
from each such certificate at such time as the shares represented by such certificate are no longer subject to the provisions of this Agreement. 
 2.4 Drag-Along Right. If the Investors holding at least eighty seven percent (87%) of the Preferred Stock, voting together as a single class on an as-converted basis (the “Requisite
Investors”), approve a sale of the Company or all or substantially all of the Company’s assets, whether by means of a merger, consolidation or sale of stock or assets, or otherwise (an “Approved Sale”), the Key Holders
and the Investors shall each consent to, vote for, and raise no objections to the Approved Sale, and (i) if the Approved Sale is structured as a merger or consolidation of the Company, or a sale of substantially all of the Company’s
assets, the Key Holders and Investors shall each waive any dissenters rights, appraisal rights or similar rights in connection with such merger, consolidation or asset sale, or (ii) if the Approved Sale is structured as a sale of the stock of
the Company, the Key Holders and Investors shall each agree to sell their Key Holder Shares and Investor Shares on the terms and conditions approved by the Requisite Investors, provided such terms do not provide that the Key Holder or Investor would
receive less than the amount that would be distributed to the Key Holder or Investor in the event the proceeds of the Approved Sale were distributed in accordance with the Company’s Certificate of Incorporation, as amended (the
“Charter”). The Key Holders and the Investors shall each take all necessary and desirable actions approved by the Requisite Investors in connection with the consummation of the Approved Sale, including the execution of such
agreements and such instruments and other actions reasonably necessary to (x) provide the representations, warranties, indemnities, covenants, conditions, non-compete agreements (with respect to the Key Holders), escrow agreements and other
provisions and agreements relating to such Approved Sale and (y) effectuate the allocation and distribution of the aggregate consideration upon the Approved Sale. Notwithstanding anything to the contrary herein, no Key Holder or Investor shall
be required to provide (a) representations and warranties in connection with an Approved Sale other than those pertaining to authorization, ownership, due execution, binding obligations and, if a sale of stock, the absence of liens on such
stock or (b) indemnification in excess of its pro rata portion of the proceeds received by the Key Holders and the Investors in such Approved Sale; provided, however, in no event shall such Key Holder or Investor, as applicable, be liable for
any amount in excess of the proceeds received by such Key Holder or Investor, as applicable, in such Approved Sale. 
 2.5
Ownership. 
 (a) Each Key Holder represents and warrants to the Investors and the Company that (i) to the extent
such Key Holder now owns any Key Holder Shares, such Key Holder owns such Key Holder Shares free and clear of liens or encumbrances, and has not, prior to or on the date of this Agreement, executed or delivered any proxy or entered into any other
voting agreement or similar arrangement other than the Prior Agreement and one which has 

  
 5 

 
expired or terminated prior to the date hereof, and (ii) such Key Holder has full power and capacity to execute, deliver and perform this Agreement, which has been duly executed and
delivered by, and evidences the valid and binding obligation of, such Key Holder enforceable in accordance with its terms. 

(b) Each Investor represents and warrants to the other Investors and the Company that (i) such Investor now owns, or will own upon
the issuance by the Company in accordance with the terms of the Amended and Restated Purchase Agreement, the Investor Shares, free and clear of liens or encumbrances, and has not, prior to or on the date of this Agreement, executed or delivered any
proxy or entered into any other voting agreement or similar arrangement other than the Prior Agreement, one that has expired or terminated prior to the date hereof and that certain voting agreement between certain Investors previously provided to
all parties to this Agreement, and (ii) such Investor has full power and capacity to execute, deliver and perform this Agreement, which has been duly executed and delivered by, and evidences the valid and binding obligation of, such Investor
enforceable in accordance with its terms. 
 3. Termination. 

3.1 Termination Events. This Agreement shall terminate and have no further force and effect, upon the earliest to occur of any one
of (a) the closing of a Qualified IPO (as defined in the Charter), (b) the closing of a Change of Control (as defined in the Charter) or (c) the date as of which the Company and the Investors terminate this Agreement by the written
consent of the Company and the holders of at least eighty percent (80%) of the Investor Shares, voting together as a single class on an as-converted basis. 
 3.2 Removal of Legend. At any time after the termination of this Agreement in accordance with Section 3.1 hereto, any holder of a stock certificate bearing the Legend may surrender such
certificate to the Company for removal of the legend, and the Company will duly reissue a new certificate without the legend. 

4. Miscellaneous. 
 4.1 Common Stock Issuable upon Exercise of Series C-2 Warrants. Immediately prior to an “Exercise Event” as defined in the Series C-2 Warrants dated of even date herewith, the Company
will, in accordance with the laws of the State of Delaware, amend the Charter to increase the authorized amount of Common Stock to satisfy the Company’s obligations to issue Common Stock upon the exercise of the Series C-2 Warrants (as defined
in the Amended and Restated Purchase Agreement). The Key Holders and the Investors agree to vote for any amendment to the Charter to increase the number of authorized shares of Common Stock in order for the Company to satisfy its obligations to
issue Common Stock upon the exercise of the Series C-2 Warrants (as defined in the Amended and Restated Purchase Agreement). 

4.2 Manner of Voting; Grant of Proxy. The voting of shares pursuant to this Agreement may be effected in person, by proxy, by
written consent, or in any other manner permitted by applicable law. If the provisions of this Agreement are construed to constitute the 

  
 6 

 
granting of proxies, such proxies shall be deemed coupled with an interest and are irrevocable for the term of this Agreement. 

4.3 Specific Enforcement. It is agreed and understood that monetary damages would not adequately compensate the Investors, or any
of them, for the breach of this Agreement by any other party, that this Agreement shall be specifically enforceable, and that any breach or threatened breach of this Agreement shall be the proper subject of a temporary or permanent injunction or
restraining order for the benefit of the Investors, or any of them. Further, each party other than the Investors, waives any claim or defense that there is an adequate remedy at law for such breach or threatened breach of this Agreement. 

4.4 Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree
to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (a) such provision shall be excluded from this Agreement, (b) the balance of
this Agreement shall be interpreted as if such provision were so excluded and (c) the balance of this Agreement shall be enforceable in accordance with its terms. 
 4.5 Entire Agreement. This Agreement and the Exhibits hereto, along with the Amended and Restated Purchase Agreement and the other documents delivered pursuant thereto, constitute the full and
entire understanding and agreement between the parties with regard to the subjects hereof and thereof and no party shall be liable or bound to any other in any manner by any oral or written representations, warranties, covenants or agreements except
as specifically set forth herein and therein. Each party expressly represents and warrants that it is not relying on any oral or written representations, warranties, covenants or agreements outside of this Agreement. 

4.6 Amendment or Waiver. This Agreement may be amended or modified (or provisions of this Agreement waived) only upon the written
consent of (i) the Company and (ii) the holders of at least eighty percent (80%) of the Investor Shares, voting together as a single class on an as-converted basis; provided that, the Company may amend Schedule A,
Schedule B, Schedule C, Schedule D, and/or Schedule E attached hereto from time to time to add information regarding (A) additional Key Holders or Investors, as applicable, that have executed and delivered Adoption
Agreements, or (B) additional Shares acquired by the Key Holders or the Investors after the date hereof, without the consent of the other parties hereto. Any amendment or waiver so effected shall be binding upon the Company, each of the parties
hereto and any assignee of any such party. Notwithstanding anything to the contrary herein, (1) the definition of “Requisite Investors” contained in Section 2.4 may not be amended, modified or waived without the written consent
of the Investors holding 80% of the Series C-1 Preferred Stock and (2) this Agreement may not be amended or modified (or any provisions of this Agreement waived) with respect to any Investor without the written consent of such Investor unless
such amendment, modification or waiver applies to all Investors in the same fashion. 
 4.7 Notices. All notices and other
communications required or permitted hereunder shall be in writing and shall be mailed by registered or certified mail, postage prepaid, or otherwise delivered by hand or by messenger, addressed (a) if to a Key Holder, at such Key Holder’s
respective address set forth on Schedule A attached hereto, or at such other address as 

  
 7 

 
such Key Holder shall have properly furnished in writing to the Company, (b) if to an Investor, at such Investor’s respective address set forth on Schedule B,
Schedule C, Schedule D or Schedule E attached hereto, as applicable, or at such other address as such Investor shall have properly furnished in writing to the Company, or (c) if to the Company, at 4900 Hopyard Road,
Suite 220, Pleasanton, CA 94588, Fax: (925) 730-0157, Attn: Corporate Secretary, or at such other address as the Company shall have properly furnished to the Key Holders and the Investors in writing. Such notices shall be deemed effective
upon (i) personal delivery to the party to be notified; (ii) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient; if not, then on the next business day; (iii) one (1) business
day after deposit with a nationally recognized overnight carrier, specifying next day delivery; or (iv) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid. 

4.8 Governing Law. This Agreement shall be governed in all respects by the laws of the State of Delaware without regard to the
conflict of laws provisions. The parties hereto agree to submit to the exclusive jurisdiction of the federal and state courts of the State of Delaware with respect to the interpretation of this Agreement or for the purposes of any action arising out
of or relating to this Agreement. 
 4.9 Successors and Assigns. The provisions of this Agreement shall inure to the
benefit of, and be binding upon, the successors in interest to any of the Key Holder Shares or Investor Shares. The Company shall not permit the transfer of any Shares on its books or issue a new certificate representing any Shares unless the person
to whom such Shares are to be transferred shall have executed and delivered an Adoption Agreement. Upon the execution and delivery of an Adoption Agreement by any transferee, such transferee shall become a party to this Agreement and shall be bound
by all of the provisions hereof as if such person were a Key Holder or Investor, as applicable, and such transferee’s signature appeared on the signature pages to this Agreement. 

4.10 Additional Shares. If after the date of this Agreement any shares or other securities are issued on, or in exchange for, any
of the Key Holder Shares or Investor Shares by reason of any stock dividend, stock split, combination of shares, reclassification, or the like, such shares or securities shall be deemed to be Key Holder Shares or Investor Shares, as the case may be,
for purposes of this Agreement. 
 4.11 Delays or Omissions. No delay or omission to exercise any right, power or remedy
accruing to any party, upon any breach, default or noncompliance by another party under this Agreement shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any
acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring. Any waiver, permit, consent or approval of any kind or character on any party’s part of any breach, default or noncompliance under this
Agreement or any waiver on such party’s part of any provisions or conditions of the Agreement must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement by law,
or otherwise afforded to any party, shall be cumulative and not alternative.

 4.12 Attorney’s Fees. If any suit or action is instituted under or in relation
to this Agreement, the prevailing party in such dispute shall be entitled to recover from the losing party all fees, costs and expenses of such suit or action (including any appeals), including without limitation, the reasonable fees and expenses of
attorneys and accountants. 
 4.13 Counterparts. This Agreement may be executed in any number of counterparts, each of
which shall be an original, and all of which together shall constitute one instrument. 
 4.14 Titles and Subtitles. The
titles and subtitles of the Sections of this Agreement are for convenience of reference only and are not to be considered in construing or interpreting this Agreement. 
 4.15 Spousal Consent. If any individual Key Holder or Investor is married on the date of this Agreement, such Key Holder’s or Investor’s spouse shall execute and deliver to the Company a
consent of spouse in the form of Exhibit B hereto (“Consent of Spouse”), effective on the date hereof. Notwithstanding the execution and delivery thereof, such consent shall not be deemed to confer or convey to the
spouse any rights in such Key Holder’s or Investor’s Shares that do not otherwise exist by operation of law or the agreement of the parties. If any individual Key Holder or Investor should marry or remarry subsequent to the date of this
Agreement, such Key Holder or Investor shall within thirty (30) days thereafter obtain his/her new spouse’s acknowledgement of and consent to the existence and binding effect of all restrictions contained in this Agreement by causing such
spouse to execute and deliver a Consent of Spouse acknowledging the restrictions and obligations contained in this Agreement and agreeing and consenting to the same.

FORM OF LEGAL OPINION 
 OF 
 ORRICK, HERRINGTON & SUTCLIFFE LLP 

 November 16, 2011 
 To the Purchasers of Series C-1 Preferred 
 Stock of Fulcrum BioEnergy, Inc. Listed

 on Exhibits A and B to the Second Amended and 
 Restated Series C Preferred Stock Purchase Agreement 
 Ladies and Gentlemen: 

We have acted as counsel for Fulcrum BioEnergy, Inc., a Delaware corporation (the “Company”), in connection with the
execution of the Second Amended and Restated Series C Preferred Stock Purchase Agreement (the “Purchase Agreement”) dated as of November 8, 2011 among the Company and the persons listed on Exhibits A and B attached thereto
(the “Purchasers”), the sale by the Company to the persons listed on Exhibit A attached to the Purchase Agreement (the “Existing Investors”) of 19,492,835 shares of Series C-1 Preferred Stock and the sale by the
Company to the persons listed on Exhibit B attached to the Purchase Agreement (the “New Investors”) and 19,101,121 shares of Series C-1 Preferred Stock and warrants to acquire shares of the Company’s capital stock (the
“Series C-2 Warrants”), which sale shall occur pursuant and subject to the terms and conditions of the Purchase Agreement, and the execution and delivery by the Company of the Fourth Amended and Restated Investors’ Rights
Agreement dated as of November 16, 2011 (the “Investors’ Rights Agreement”), the Fourth Amended and Restated Right of First Refusal and Co-Sale Agreement dated as of November 16, 2011 (the “Co-Sale
Agreement”) and the Fourth Amended and Restated Voting Agreement dated as of November 16, 2011 (the “Voting Agreement”). This letter is given to you pursuant to Section 4.5 of the Purchase Agreement. The Purchase
Agreement, the Investors’ Rights Agreement, the Co-Sale Agreement, and the Voting Agreement are referred to herein collectively as the “Transaction Documents.” Unless defined herein, capitalized terms have the meanings given
them in the Transaction Documents. 
 We have made such legal examination as we have deemed necessary for the purpose of
rendering our opinions set forth in this letter. As to matters of fact material to the opinions expressed herein, we have relied upon the representations and warranties as to factual matters contained in and made by the Company pursuant to the
Purchase Agreement and the certificate of Eric Pryor the Chief Financial Officer of the Company (the “Opinion Certificate”) and upon certificates and statements of government officials and of officers of the Company. In addition, we
have examined originals or copies of documents, corporate records and other writings that we considered relevant for the purpose of rendering our opinions in this letter. In such examination, we have assumed the genuineness of all signatures on
original documents (other than the 

 To the Purchasers of Series C Preferred 
 Stock of Fulcrum BioEnergy, Inc. 
 November 16, 2011 

Page 2 
  
 Company with respect to the Transaction Documents) and the conformity to original documents of all copies submitted to us. In making our examination of documents executed by entities other than the
Company, we have assumed that (a) each other entity had the power to enter into and perform all its obligations thereunder; (b) each other entity duly authorized, executed and delivered such documents; (c) each such document
constitutes a valid and binding obligation of each such other entity, enforceable against such other entity in accordance with its terms; and (d) there is no fact or circumstance relating to you or your business that might prevent you from
enforcing any of the rights provided for in the Transaction Documents. We have also assumed that there are no extrinsic agreements or understandings among the parties to the Transaction Documents that would modify or interpret the terms of the
Transaction Documents or the respective rights or obligations of the parties thereunder. 
 Whenever a statement herein is
qualified by the phrase “to our knowledge” or “known to us” or similar phrases it is intended to indicate that, during the course of our representation of the Company in the transaction described in the first
paragraph of this letter, no information that would give us current actual knowledge of the inaccuracy of such statement has come to the attention of those attorneys presently in this firm who have rendered legal services in connection with such
representation. However, we have not undertaken any independent investigation or review to determine the accuracy of any such statement, and any limited inquiry undertaken by us during the preparation of this letter should not be regarded as such an
investigation or review, and no inference as to our knowledge of any matters bearing on the accuracy of any such statement should be drawn from the fact of our representation of the Company. 

Where statements in this letter are qualified by the term “material”, those statements involve judgments and opinions as
to the materiality or lack of materiality of any matter to the Company or its business, assets or financial condition that are entirely those of the Company and its officers, after having been advised by us as to the legal effect and consequences of
such matters. 
 We express no opinion as to matters governed by any laws other than the federal laws of the United States of
America, the laws of the State of California and the corporate law of the State of Delaware. We express no opinion as to any choice of law provision, and no opinion to the extent that the laws of any jurisdiction other than those identified above
are applicable to the Transaction Documents or the transactions contemplated thereby. We are not admitted to practice law in the State of Delaware, and our opinions as to Delaware corporate law are based on a review of a standard compilation of the
Delaware General Corporation Law and the reported decisions of the Delaware courts interpreting that Law.

We note that the parties to the Transaction Documents have designated the laws of the State of Delaware as the laws governing the
Transaction Documents. Since our opinions as to Delaware law are limited to Delaware corporate law, our opinions as to the legality, validity, binding effect and enforceability of the Transaction Documents are premised on the result that would be
obtained if a California court were to apply the internal laws of the State of California to the Transaction Documents (notwithstanding the designation therein of the laws of the State of Delaware). If the Transaction Documents are not legal, valid,
binding and enforceable under the laws of the State of Delaware, the Transaction Documents might not be enforced by a California court if it gave effect to the parties’ choice of law. 

In rendering the opinions set forth in paragraph (i) below with respect to corporate good standing and qualification to do business
as a foreign corporation, we have relied exclusively on certificates of public officials. 
 In rendering the opinion set forth
in paragraph (iii) below relating to the fully paid status of all of the issued shares of capital stock of the Company, we have relied without independent verification on the Opinion Certificate, to the effect that the Company has received the
consideration approved by the Company’s Board of Directors for all of the issued shares of capital stock of the Company. 

In rendering the opinion and providing the confirmation set forth in paragraph (iii) below, we have relied without further
investigation on our review of the Company’s Sixth Amended and Restated Certificate of Incorporation (the “Restated Charter”), the Bylaws as amended to date, the minute books relating to meetings and written consents of the
Board of Directors and stockholders of the Company, the stock records of the Company and statements in the Opinion Certificate relating to the capitalization of the Company (collectively, the “Capitalization Records”). The Company
has represented to us that the Capitalization Records completely and accurately describe all of the Company’s issuances of shares of its capital stock, options, warrants, conversion privileges, preemptive rights or other rights to purchase
shares of its capital stock. 
 In rendering the opinion in paragraph (v) below, the term “Contractual
Obligations” shall mean only those agreements to which the Company is a party or by which it is bound and which are expressly identified in Exhibit A hereto. We have further assumed that each such Contractual Obligation will be
interpreted in accordance with its plain meaning. We have not, however, reviewed any financial covenants or similar provisions in the Contractual Obligations that require financial calculations to ascertain compliance, and no opinion is provided
with respect thereto. We also do not express any opinion on parol evidence bearing on interpretation or construction of such agreements.

In rendering the opinion in paragraph (v) below relating to violations of United States federal, Delaware corporate or California
laws, rules or regulations applicable to the Company, such opinion is limited to such laws, rules or regulations that in our experience are typically applicable to a transaction of the nature contemplated by the Transaction Documents. 

In rendering the opinions expressed in paragraph (v) below, please note that we have not conducted searches of the dockets of any
court or administrative agency whatsoever. 
 In rendering the opinions expressed in paragraphs (v), (vi) and
(vii) below, we have assumed and relied upon, and express no opinion with respect to, the following: (a) that the representations and warranties of the Purchasers as to factual matters set forth in the Transaction Documents are true and
complete; (b) that any wire transfers, drafts or checks or other consideration tendered by the Purchasers will be honored or received; (c) the information provided by the Company to the Purchasers in connection with the offer and sale of
the Stock and Series C-2 Warrants is accurate and complete; (d) that the Company’s representations to us that the Company has made no offer to sell the Stock and Series C-2 Warrants by means of any general solicitation or in connection
with the publication of any advertisement therefor and that no offer or sale of the Stock and Series C-2 Warrants has been made or will be made in any states outside of California where such offer or sale would be contrary to applicable law are
accurate and complete; and (e) that the representations and warranties as to factual matters made by the Company and all prior purchasers of the Company’s securities given in connection with the sale of such securities are true and
complete. 
 The opinions hereinafter expressed are subject to the following further qualifications: 

(1) Our opinions are qualified by limitations imposed by bankruptcy, insolvency, reorganization, arrangement, fraudulent conveyance,
moratorium, or other laws relating to or affecting the rights of creditors generally. 
 (2) Our opinions are qualified by
general principles of equity, including without limitation concepts of materiality, reasonableness, good faith and fair dealing, and the possible unavailability of specific performance or injunctive relief, regardless of whether such enforceability
is considered in a proceeding in equity or at law. 
 (3) We note that a requirement that provisions of the Transaction Documents
may only be waived in writing may not be enforceable to the extent an oral agreement has been adopted modifying provisions of the Transaction Documents or an implied agreement by trade practice or course of conduct has given rise to a waiver.

  
 -4-

(4) We note that our opinions are based upon current statutes, rules, regulations, cases and official interpretive opinions, and cover
certain items that are not directly or definitively addressed by such authorities. 
 (5) We express no opinion as to the effect
of judicial decisions that may permit the introduction of extrinsic evidence to modify the terms or the interpretation of the Transaction Documents. 
 (6) We express no opinion as to the enforceability of provisions of the Transaction Documents expressly or by implication waiving broadly or vaguely stated rights, or waiving rights granted by law where
such waivers are against public policy. 
 (7) We express no opinion as to the enforceability of any provision of any Transaction
Document purporting to (a) waive rights to trial by jury, service of process or objections to the laying of venue or to forum in connection with any litigation arising out of or pertaining to the Transaction Documents, (b) exclude conflict
of law principles, (c) establish particular courts as the forum for the adjudication of any controversy relating to the Transaction Documents, (d) establish the laws of any particular state or jurisdiction for the adjudication of any
controversy relating to the Transaction Documents, (e) establish evidentiary standards or make determinations conclusive or (f) provide for arbitration of disputes. 
 (8) We express no opinion as to the enforceability of any provisions of the Transaction Documents providing that (a) rights or remedies are not exclusive, (b) rights or remedies may be exercised
without notice, (c) every right or remedy is cumulative and may be exercised in addition to or with any other right or remedy, (d) the election of a particular remedy or remedies does not preclude recourse to one or more other remedies,
(e) liquidated damages are to be paid upon the breach of any Transaction Document or (f) the failure to exercise, or any delay in exercising, rights or remedies available under the Transaction Documents will not operate as a waiver of any
such right or remedy. 
 (9) We express no opinion as to compliance with applicable antifraud statutes, rules or regulations of
applicable United States federal or state laws concerning the issuance or sale of securities, including, without limitation, (a) the accuracy and completeness of the information provided by the Company to the Purchasers in connection with the
offer and sale of the Stock and Series C-2 Warrants, and (b) the accuracy or fairness of the past, present or future fair market value of any securities. 
 (10) We express no opinion as to the enforceability of the indemnification and contribution provisions in the Investors’ Rights Agreement to the extent that the provisions

  
 -5-

 To the Purchasers of Series C Preferred 
 Stock of Fulcrum BioEnergy, Inc. 
 November 16, 2011 

Page 6 
  
 
thereof may be limited by United States federal or state laws concerning the issuance or sale of securities or by public policy or statutory provisions relating to indemnification and
contribution. 
 (11) We express no opinion as to the effect of any law or equitable principle that provides that a court may
refuse to enforce, or may limit the application of, a contract or any clause thereof that the court finds to have been unconscionable at the time it was made or contrary to public policy. 

(12) We express no opinion as to your compliance with any United States federal or state law relating to your legal or regulatory status
or the nature of your business. 
 (13) We have assumed that, and we express no opinion as to whether, the Transaction Documents
and the transactions contemplated thereby were fair, just and reasonable to the Company within the meaning of Section 144 of the General Corporation Law of the State of Delaware and Section 310 of the California Corporations Code and we
express no opinion as to whether the members of the Company’s Board of Directors have complied with their fiduciary duties in connection with the authorization and performance of the Transaction Documents and the transactions contemplated
thereby. 
 (14) We express no opinion as to the enforceability of any provisions in the Transaction Documents concerning the
voting of the Company’s capital stock, including without limitation those provisions set forth in the Voting Agreement. 

(15) We express no opinion as to compliance with any United States federal or state antitrust statutes, rules or regulations, including
without limitation the Hart-Scott-Rodino Antitrust Improvements Act of 1976, or as to compliance with the Small Business Investment Act of 1958. 
 Based upon and subject to the foregoing, and except as specifically set forth in the Purchase Agreement or the Schedule of Exceptions, we are of the opinion that: 

(i) The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the jurisdiction of its
incorporation, and has the corporate power and authority to own its properties and to conduct its business as, to our knowledge, it is presently conducted. The Company is qualified to do business as a foreign corporation in the State of California.

 (ii) The Company has the corporate power and authority to execute and deliver the Transaction Documents, to sell and issue the
Stock and the Series C-2 Warrants thereunder, to 

  
 -6-

 To the Purchasers of Series C Preferred 
 Stock of Fulcrum BioEnergy, Inc.

Page 7 
  
 
issue the Common Stock issuable upon conversion of the Stock and the shares of Common Stock or Series C-2 Preferred Stock, as applicable, issuable upon exercise of the Series C-2 Warrants (such
stock, the “Warrant Stock”) and to perform its obligations under the Transaction Documents. 
 (iii) The
authorized capital stock of the Company consists or will, upon the filing of the Restated Charter, consist of 90,000,000 shares of Common Stock, par value $0.001 per share, of which 3,316,297 shares are issued and outstanding prior to the Closing,
and 181,887,412 shares of Preferred Stock, 6,471,573 shares of which have been designated Series A Preferred Stock, all of which are issued and outstanding prior to the Closing, 14,000,000 shares of which have been designated Series B-1
Preferred Stock, all of which are issued and outstanding prior to the Closing, 13,450,762 shares of which have been designated Series B-2 Preferred Stock, all of which are issued and outstanding prior to the Closing, 38,593,956 shares of which
have been designated Series C-1 Preferred Stock, 13,905,765 of which are issued and outstanding prior to the Closing and 19,101,121 shares of which have been designated Series C-2 Preferred Stock, none of which are issued and outstanding
prior to the Closing. All of such issued and outstanding shares are duly authorized, validly issued, fully paid and nonassessable. The Company has reserved an aggregate of 72,786,291 shares of Common Stock for issuance upon conversion of the Series
A Preferred Stock, Series B Preferred Stock and Series C-1 Preferred Stock, 19,101,121 shares of Series C-2 Preferred Stock for issuance upon exercise of the Warrants, an aggregate of 38,593,956 shares of Series C-1 Preferred Stock for issuance
under the Purchase Agreement and 9,000,000 shares of Common Stock for issuance under the Company’s 2007 Stock Incentive Plan (the “Stock Plan”). To our knowledge, except for the Warrants, conversion privileges of the Preferred
Stock and the outstanding options issued pursuant to the Stock Plan, and except as set forth in the Investors’ Rights Agreement, there are no preemptive rights, options or warrants or other conversion privileges or rights presently outstanding
to purchase any of the authorized but unissued stock of the Company that have not been waived and there are no anti-dilution provisions with respect to the Company’s capital stock except as set forth in the Restated Charter. 

(iv) All corporate action on the part of the Company, its directors and stockholders necessary for the authorization, execution, delivery
and performance of the Transaction Documents by the Company, the authorization, sale, issuance and delivery of the Stock (and the Common Stock issuable upon conversion thereof) and the Series C-2 Warrants (and the shares of Series C-2 Preferred
Stock issuable upon exercise thereof) and the execution and filing with the Secretary of State of the State of Delaware of the Restated Charter, has been taken. The Restated Charter has been duly executed by the Company. The Transaction Documents
and the Series C-2 Warrants have been duly executed and delivered by the Company and constitute valid and 

  
 -7-

 To the Purchasers of Series C Preferred 
 Stock of Fulcrum BioEnergy, Inc. 
 November 16, 2011 

Page 8 
  
 
binding obligations of the Company enforceable against the Company in accordance with their terms. Shares of Common Stock issuable upon conversion of the Stock and shares of Series C-2 Preferred
Stock issuable upon exercise of the Series C-2 Warrants have been duly and validly reserved. When issued in compliance with the provisions of the Purchase Agreement and the Restated Charter, the Stock (and the shares of Common Stock issuable upon
conversion of the Stock) will be duly authorized, validly issued, fully paid and nonassessable. 
 (v) The execution, delivery
and performance of the Transaction Documents, the issuance of the Stock (and the Common Stock issuable upon conversion of the Stock) and the Series C-2 Warrants (and the Series C-2 Preferred Stock issuable upon exercise of the Series C-2 Warrants),
have not resulted and will not as of the Closing result in (A) a violation of or conflict with the Restated Charter or Bylaws, (B) a violation of any statute, rule or regulation of United States federal, Delaware corporate or California
law, (C) a violation of any judgment or order (if any) known to us to be applicable to the Company or (D) a material default under or breach of any Contractual Obligation. 

(vi) No consent, approval or authorization of or designation, declaration or filing with, any United States federal, Delaware corporate or
California governmental authority on the part of the Company is required in connection with the valid execution and delivery of the Transaction Documents, or the offer, sale or issuance of the Stock (and the Common Stock issuable upon conversion
thereof) or the Series C-2 Warrants and the Warrant Stock, except the notice filings required by Rule 503 under the Securities Act of 1933, as amended (the “33 Act”) and Section 25102.1 of the California Corporate
Securities Law of 1968, as amended (the “California Securities Law”). 
 (vii) The offer and sale of the Stock
and the Series C-2 Warrants and, assuming the Series C-2 Warrants were exercised on the date hereof and the Shares and the Warrant Stock were converted on the date hereof, the Shares and the Warrant Sock so converted are exempt from the registration
requirements of the 33 Act and from the qualification requirements of the California Securities Law. 
 In addition, we
advise you supplementally as a matter of fact and not opinion that, except as disclosed in the Purchase Agreement or the Schedule of Exceptions, to our knowledge, there are no actions, proceedings or governmental investigations pending or threatened
against the Company. Please note that we have not conducted a docket search in any jurisdiction with respect to litigation that may be pending against the Company or any of its officers or directors, nor have we undertaken any further inquiry
whatsoever with respect to such actions, proceedings or investigations other than to request the Opinion Certificate from the Company.
