conditioned or delayed). 
 (b) Renewal Option. This Lease automatically renews for a period of one (1) year to commence
upon expiration of the Operations Term, unless either party provides written notice of termination to the other party as provided herein at least six (6) months prior to expiration of the Operations Term (the “Renewal

purposes for which they are leased and waives any defects in the Premises. Except as expressly provided herein, Tenant acknowledges that neither Landlord nor any other

warranty of any kind, express or implied, with respect to the suitability or fitness of the Premises or any other portion of the Site for the conduct of Tenant’s business. Except as expressly provided herein, Tenant has not relied on any
representations and warranties made by Landlord, any of Landlord’s agents or any other Landlord Party. Nothing in this Section 3(c) shall relieve Landlord from any of its express repair or maintenance obligations under

of the Interconnection Electric Facilities Premises (the “Interconnection Electric Facilities Premises Delivery Date”), execute and deliver to the other party an Acceptance of Possession Certificate in the form of
Exhibit D attached hereto; provided, however, that the failure to execute and deliver the Acceptance of Possession Certificate shall not affect in any manner either party’s rights or obligations pursuant to this Lease. After the

Facilities Premises shall constitute part of the Premises for all purposes of this Lease, and (iii) Landlord shall have no obligation to perform or cause to be performed any maintenance or repair work to the Interconnection Electric Facilities
or otherwise in the Interconnection Electric Facilities Premises, except as expressly set forth in this Lease.

responsible for installing or arranging for the installation, at its cost, of any connections for such basic utilities from such tie-in points to the applicable Tenant Improvements. 

6. Landlord Work. All Landlord Work shall be performed in accordance with that certain Purchase and Sale Agreement with respect to the

 8. Waiver of Property Claims; No Subrogation. Landlord and Tenant each waives any Claim it
might have against the other for any damage to or theft, destruction, loss, or loss of use of any property, to the extent the same is insured against under any insurance policy of the types described in Exhibit F that covers the
Premises, the Property, the Facility, Landlord’s Equipment, Tenant Improvements or its respective business, as applicable, or is required to be insured against under the terms hereof, regardless of whether the negligence of the other party
or its agents, invitees, contractors or employees caused such Claim. Each party shall cause its insurance carrier to endorse all applicable policies waiving the carrier’s rights of recovery under subrogation or otherwise against the other
party. Notwithstanding any provision in this Lease to the contrary, the Landlord Parties shall not be liable to Tenant or to any party claiming by, through or under any Tenant Party (and Tenant hereby releases the Landlord Parties from any claim or
responsibility for) any damage to or destruction, loss, or loss of use, or theft of any property of any Tenant Party located in or about the Site, caused by casualty, theft, fire, third parties or any other matter or cause, regardless of whether
the negligence of any party caused such loss in whole or in part. Tenant acknowledges that Landlord shall not carry insurance on, and shall not be responsible for damage to, any property of any Tenant Party located in or about the Site,
including the Tenant Improvements. The provisions of this Section 8 shall survive the expiration or earlier termination of this Lease.  

9. Repairs and Alterations.

and repair at Tenant’s sole cost and expense the Interconnection Electric Facilities. 
 (b) Landlord Repair Obligations.
Landlord will maintain the Access Areas in good order, condition and repair and free from rubbish, ice and snow, ordinary wear and tear excepted and shall be responsible for any of Landlord’s equipment, including, without limitation,
geomagnetic sensors and sewer pipe (collectively, the “Landlord’s Equipment”), if any, located within the Access Areas. Tenant shall pay the costs of the foregoing maintenance if necessitated
due to the negligent acts or omissions of any Tenant Party in order to place the Access Areas and Landlord’s Equipment in substantially the same condition as existed immediately prior to such negligent act or omission. For the avoidance of
doubt, there is no Landlord’s Equipment located within the Premises.

 *** Certain confidential portions (indicated by brackets and asterisks) have been omitted from this
exhibit because such information is both (i) non-material and (ii) would be competitively harmful if publicly disclosed. 
  

 (c) Tenant Alterations. Tenant shall not make alterations, additions or
improvements to the Premises (except for the Tenant Improvements) (collectively, “Alterations”) without first obtaining the written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or
delayed. Prior to starting work on any Alteration, Tenant shall furnish to Landlord for review and approval: plans and specifications (if applicable); names of proposed contractors; copies of contracts; necessary permits and approvals; and evidence
of contractors’ and subcontractors’ insurance. Changes to the plans and specifications must also be submitted to Landlord for its approval. Landlord’s approval of an Alteration shall not be a representation by Landlord that the
Alteration complies with applicable Laws or will be adequate for Tenant’s use. Alterations shall be constructed in a good and workmanlike manner in accordance with Laws and Regulations and insurance requirements. Tenant shall reimburse Landlord
for out-of-pocket sums paid by Landlord for third party examination of Tenant’s plans for Alterations, not to exceed $2,500. Notwithstanding the foregoing,

affidavits, full and final waivers of liens, receipts and bills covering all labor and materials. 
 10. Project. 

(a) The Project and its constituent parts, together with any and all improvements or other features constructed on, or personal property
installed or placed on the Premises by or for Tenant, including, without limitation, the Tenant Improvements, machinery, fixtures, trade fixtures, equipment, racking, inverters, cables, solar panels and other personal property (collectively,
“Tenant’s Personal Property”) are personal property within the meaning of Article 9 of the Uniform Commercial Code (the “UCC”) regardless of the manner of attachment to the Premises. Tenant’s
Personal Property is and shall at all times during the Term be deemed to be the property of Tenant, to be removed at Tenant’s expense upon the expiration or earlier termination of the Term. The creation, attachment and perfection of security
interests in Tenant’s Personal Property shall be governed exclusively by Article 9 of the UCC. For the avoidance of doubt and without limiting the foregoing, Landlord hereby waives all rights to distraint, possession or landlord’s lien
against Tenant’s Personal Property, if any, and shall not cause the creation of, or attachment to, Tenant’s Personal Property of any liens (including mechanics’ and judgment liens) or other encumbrances. For the avoidance of doubt,
Landlord is not responsible for payment of any taxes or payments in lieu of taxes assessed on Tenant’s Personal Property. 
 (b) The
parties hereto acknowledge that the Premises consist of land only and do not include Tenant’s Personal Property. Any claim to a lien or encumbrance upon the Premises, arising from any act or omission of Landlord, shall accrue only against the
real estate owned by Landlord, and not against Tenant’s Personal Property, and shall be subject to this Lease. If any such lien or encumbrance shall be filed against Tenant’s Personal Property as a result of Landlord’s actions,
Landlord shall, without cost or expense to Tenant, within 60 days of Landlord’s receipt of notice of the filing, cause such lien or encumbrance to be discharged of record by payment, statutory lien release bond, court order or otherwise as
provided by law. Landlord shall not permit any sale, foreclosure or forfeiture of the Premises by reason of nonpayment of a lien caused by Landlord or anyone claiming by or through Landlord. Landlord shall immediately notify Tenant of, and send
Tenant a copy of, any notice Landlord receives claiming that Landlord is late or in default regarding any obligation Landlord has to pay money to any lender or third party holding a mortgage or other lien affecting the Premises.

 *** Certain confidential portions (indicated by brackets and asterisks) have been omitted from this
exhibit because such information is both (i) non-material and (ii) would be competitively harmful if publicly disclosed. 
  

 (c) Tenant shall keep Landlord’s interest in the Site free and clear of all liens and
claims of liens for labor and services performed on, and materials, supplies and equipment furnished to the Premises in connection with Tenant’s use of the Premises. If any such lien is filed, Tenant shall, within sixty (60) days of
receiving notice of the filing, either bond around such lien, establish an appropriate reserve or security therefor, or otherwise remove such lien from the Land pursuant to applicable laws. 

11. Assignment and Subletting. 
 (a)
Landlord’s Consent Required; Permitted Transfers. Tenant shall not assign, transfer or encumber any interest in this Lease or sublease or allow any third party to use any portion of the Premises (collectively or individually, a
“Transfer”) without the prior written consent of Landlord, which may not be unreasonably withheld, conditioned or delayed. Any attempted Transfer in violation of this Section is voidable at Landlord’s option.
Notwithstanding anything contained in this Lease to the contrary, Tenant may assign its entire interest under this Lease to a successor to Tenant by purchase, merger, consolidation or reorganization without the consent of Landlord or to a special
purpose entity formed to hold the Lease (such transfer being a “Permitted Transfer” and such transferee being a “Permitted Transferee”); provided, however, that Tenant shall provide written notice to
Landlord of any such Permitted Transfer, including the identity of the Permitted Transferee, a copy of the proposed assumption or transfer document(s), and reasonable information regarding the Permitted Transferee’s financial wherewithal and
qualifications with respect to the Permitted Use, prior to or promptly following such Permitted Transfer (it being understood that Tenant’s providing such written notice and information to Landlord is solely for informational purposes, and
shall not be construed as giving Landlord any consent rights hereunder with respect to any Permitted Transfer or Permitted Transferee). 

(b) Consent Parameters/Requirements. As part of Tenant’s request for, and as a condition to, Landlord’s consent to a
Transfer (except for a Permitted Transfer, for which no consent shall be required), Tenant shall provide Landlord with financial statements for the proposed transferee, a complete copy (unexecuted) of the proposed assignment or sublease and other
contractual documents, and such other information as Landlord may reasonably request. Landlord shall then have the right (but not the obligation) to terminate this Lease as of the date the Transfer would have been effective with respect to the
portion of the Premises which Tenant desires to Transfer; provided, however, Tenant may withdraw its request for a proposed Transfer and in such event, this Lease shall continue in full force and effect as if Tenant had not requested Landlord’s
consent to the proposed Transfer and Landlord shall not have the right to terminate this Lease as set forth above in the event of a Permitted Transfer. Except for a Permitted Transfer in which the Permitted Transferee assumes all of Tenant’s
obligations hereunder, in no event shall any Transfer release or relieve Tenant from any obligation under this Lease, nor shall the acceptance of Fixed Rent from any assignee, subtenant or occupant constitute a waiver or release of Tenant from any
of its obligations or liabilities under this Lease. Tenant shall reimburse Landlord an amount equal to Landlord’s actual out-of-pocket costs for the review of any
requested Transfer, not to exceed $1,000. Landlord’s consent to any Transfer will not constitute a waiver of Landlord’s right to approve or disapprove any subsequent Transfer. 

(c) Change in Control of Tenant. If Tenant is a corporation, limited liability company, partnership, or similar entity, and if
there is a change in control of Tenant (including by merger, consolidation or reorganization), such change of control shall constitute a Transfer. The foregoing shall not apply so long as, both before and after the Transfer, Tenant is an entity
whose outstanding stock is listed on a recognized U.S. securities exchange, or if at least 80% of its voting stock is owned by another entity, the voting stock of which is so listed; provided, however, Tenant shall give Landlord written notice at
least 30 days prior to the effective date of such change in control. 

  
 10 

 *** Certain confidential portions (indicated by brackets and asterisks) have been omitted from this
exhibit because such information is both (i) non-material and (ii) would be competitively harmful if publicly disclosed. 
  

 (d) Options. Except as otherwise expressly provided in this Lease, any option
granted to Tenant in this Lease, including, without limitation, any option to extend, renew or terminate, or any right to lease other space at the Property, is personal to the original Tenant and any Permitted Transferee and may be exercised only by
the original Tenant or any Permitted Transferee while occupying the entire Premises, and may not be exercised or be assigned, voluntarily or involuntarily, by or to any person or entity other than the original Tenant or any Permitted Transferee. The
options, if any, herein granted to Tenant are not assignable separate and apart from this Lease, nor may any option be separated from this Lease in any manner, either by reservation or otherwise.  

12. Landlord’s Representations. Landlord represents and warrants to Tenant that, as of the Effective Date,
(1) Landlord has received no written notice of any violations of Laws or litigation pending (or threatened in writing) against Landlord in connection with the Premises; (2) except as may be disclosed in applicable public records, or
inchoate liens that arise by operation of law, Landlord has no actual knowledge of any title defects or encumbrances that would prevent or interfere with the Permitted Use in any material respect; and (3) the Site is currently served by basic
utilities. 
 13. Indemnity. 
 (a)
Tenant Indemnity. Subject to Section 8 and Section 20, Tenant shall defend, indemnify, and hold harmless the Landlord Parties from and against all Claims arising from any injury to or
death of any person or the damage to or theft, destruction, loss, or loss of use of, any property or inconvenience (i) occurring in or on the Site (other than within the Premises) to the extent caused by the negligence or willful misconduct of
any Tenant Party, (ii) occurring in the Premises, or (iii) arising out of the installation, operation, maintenance, repair or removal of any property (including any Tenant Improvements) of any Tenant Party located in or about the Property,
if any, including the Tenant Improvements and (from and after the Interconnection Electric Facilities Delivery Date) the Interconnection Electric Facilities. It being agreed that clauses (ii) and (iii) of this indemnity are
intended to indemnify the Landlord Parties against the consequences of their own negligence, even when Landlord or its agents are jointly, comparatively, contributively, or concurrently negligent with any Tenant Party, and even though any such
claim, cause of action or suit is based upon or alleged to be based upon the strict liability of any Landlord Party; however, such indemnity shall not apply to the sole or gross negligence or willful misconduct of the Landlord Parties. 

(b) Landlord Indemnity. Subject to Section 8 and Section 20, Landlord shall
defend, indemnify, and hold harmless the Tenant Parties from and against all Claims arising from any injury to or death of any person or the damage to or theft, destruction, loss, or loss of use of, any property or inconvenience arising from any
occurrence in or on the Property to the extent caused by the negligence or willful misconduct of any Landlord Party. Notwithstanding anything in this Lease to the contrary, Landlord’s indemnity obligations under this Lease shall be limited to
the extent any such claim is insured against under the terms of any insurance policy maintained by Landlord (or is required to be maintained by Landlord under the terms of this Lease). 

  
 11 

 *** Certain confidential portions (indicated by brackets and asterisks) have been omitted from this
exhibit because such information is both (i) non-material and (ii) would be competitively harmful if publicly disclosed. 
  

 (c) Indemnity Procedures. The indemnities set forth in this Lease shall survive
termination or expiration of this Lease and shall not terminate or be waived, diminished or affected in any manner by any abatement or apportionment of Fixed Rent under any provision of this Lease. If any proceeding is filed for which indemnity is
required hereunder, the indemnifying party agrees, upon request therefor, to defend the indemnified party in such proceeding at its sole cost utilizing counsel satisfactory to the indemnified party. The parties acknowledge that the Purchase
Agreement and the Energy Agreement may contain additional indemnity provisions, but the indemnities contained in this Section 13 are the exclusive indemnities between the parties with respect to this Lease, and any
indemnities contained in the Purchase Agreement or the Energy Agreement shall apply solely to the respective subject matter thereof. 
 14.
Insurance. Tenant and Landlord shall maintain insurance in accordance with the terms of Exhibit F. 

15. [Intentionally Omitted]. 
 16. Casualty
Damage. If all or any material part of the Premises is damaged by fire or other casualty, Tenant shall have the right to terminate this Lease by notifying Landlord in writing within 90 days after the date of the fire or other casualty;
provided that Tenant is provided at least 60 days to vacate. If Tenant does not terminate this Lease under this Section 16, Tenant shall repair and restore the Premises (including the Tenant Improvements) or Alterations
made by, or installed by Tenant, in the Premises and the payment of Fixed Rent will not abate; provided, however, that if Tenant terminates this Lease, Tenant shall not be required to repair or restore the Premises (such repair and restoration
obligations being Landlord’s obligation) and Tenant shall remove Tenant’s Improvements or Alterations as set forth in Section 27 of this Lease. However, in no event shall Landlord be required to spend more than the insurance proceeds
received by Landlord. Landlord shall not be liable for any loss or damage to Tenant’s Personal Property or to the business of Tenant resulting in any way from the fire or other casualty or from the repair and restoration of the damage. Landlord
and Tenant hereby waive the provisions of any Law relating to the matters addressed in this Section, and agree that their respective rights for damage to or destruction of the Premises shall be those specifically provided in this Lease, which shall
constitute an express agreement between the parties with respect thereto. 
 17. Condemnation. Either party may terminate this Lease if the
whole of the Premises are taken or condemned, or Tenant may terminate if any material part of the Premises are taken or condemned, in either case for any public or quasi-public use under Law, by eminent domain or private purchase in lieu thereof (a
“Taking”). Any such termination shall be effective as of the date the physical taking of the Premises occurs. If this Lease is not terminated, the Premises shall, if applicable, be appropriately adjusted by Landlord but Fixed
Rent will not be abated. All compensation awarded for a Taking, or sale proceeds, shall be the property of Landlord, any right to receive compensation or proceeds being expressly waived by Tenant. However, Tenant may file a separate claim for
Tenant’s Personal Property and relocation expenses.

 *** Certain confidential portions (indicated by brackets and asterisks) have been omitted from this
exhibit because such information is both (i) non-material and (ii) would be competitively harmful if publicly disclosed. 
  

 18. Events of Default. It shall be an automatic Default (defined below) by Tenant if the
interest of Tenant in and to any portion of the Site is levied on under execution or other legal process, or any petition is filed by or against Tenant to declare Tenant a bankrupt or to delay, reduce or modify Tenant’s debt or obligations and
the same is not dismissed within 90 days after the date of such filing, or if Tenant is declared insolvent according to law, or any general assignment of Tenant’s property is made for the benefit of creditors, or a receiver or trustee is
appointed for Tenant or its property. Tenant shall also be considered to be in default under this Lease upon the occurrence and continuance of any of the following events of default (each, a “Default”): 

(a) Tenant’s failure to perform any of the obligations of Tenant in the manner set forth in Sections 4,
14, 23 or 24 (a “Time Sensitive Default”) where such failure shall continue beyond the time period following written notice from Landlord to Tenant, if any, as required in the applicable Section of this
Lease. 
 (b) Tenant’s failure (other than a Time Sensitive Default) to comply with any term of this Lease, if the failure is not cured
within 30 days after Tenant’s receipt of written notice from Landlord of such default. However, if Tenant’s failure to comply cannot reasonably be cured within 30 days, Tenant shall be allowed additional time (not to exceed an
additional 30 days) as is reasonably necessary to cure the failure so long as: (1) Tenant commences to cure the failure within the 30 day period following Landlord’s initial written notice, and (2) Tenant diligently pursues a
course of action that will cure the failure and bring Tenant back into compliance with this Lease. 
 (c) The occurrence of any event of
default (beyond all applicable notice and cure periods) by Tenant under the Energy Agreement. 
 19. Remedies. 

(a) Landlord’s Remedies. Upon the occurrence and continuance of any Default by Tenant, Landlord shall have the right without
notice or demand (except as required in Section 18) to pursue any of its rights and remedies at law or in equity, including any one or more of the following remedies: 

(1) Terminate this Lease; 
 (2) Re-enter the Premises and terminate Tenant’s right of possession of the Premises without terminating this Lease; and/or 

(3) Withhold or suspend payment of sums Landlord would otherwise be obligated to pay to Tenant under or in connection with this Lease. 

(b) Measure of Damages. If Landlord either terminates this Lease or terminates Tenant’s right to possession of the Premises,
Tenant shall immediately surrender and vacate the Premises and pay Landlord on demand: (a) all unpaid Fixed Rent, if any; (b) interest on all unpaid Fixed Rent and any other sums due and owing from Tenant to Landlord under this Lease from
the date due at a rate equal to the lesser of 8% per annum or the highest interest rate permitted by applicable Law; (c) all expenses reasonably incurred by Landlord in enforcing its rights and remedies under this Lease, including all
reasonable attorneys fees and expenses. 

  
 13 

 *** Certain confidential portions (indicated by brackets and asterisks) have been omitted from this
exhibit because such information is both (i) non-material and (ii) would be competitively harmful if publicly disclosed. 
  

 (c) Tenant Not Relieved from Liabilities. The repossession or re-entering of all or any part of the Premises shall not relieve Tenant of its liabilities and obligations under this Lease. Each right and remedy of Landlord shall be cumulative and in addition to any other right
and remedy now or subsequently available to Landlord at law or in equity. If Tenant fails to pay any amount when due hereunder (after the expiration of any applicable cure period), Landlord shall be entitled to receive interest on any unpaid item
from the date initially due (without regard to any applicable grace period) at a rate equal to the lesser of 8% per annum or the highest rate permitted by Law. However, in no event shall the charges permitted under this
Section 19(c) or elsewhere in this Lease, to the extent they are considered interest under applicable Law, exceed the maximum lawful rate of interest. If any payment by Tenant of an amount deemed to be interest results in
Tenant having paid any interest in excess of that permitted by Law, then it is the express intent of Landlord and Tenant that all such excess amounts theretofore collected by Landlord be credited against the other amounts owing by Tenant under this
Lease. Receipt by Landlord of Tenant’s keys to the Premises shall not constitute an acceptance or surrender of the Premises. 
 (d)
No Mitigation of Damages. Given the amount of Fixed Rent payable by Tenant under this Lease, Tenant agrees that Landlord will not be required to mitigate damages by reletting the Premises. 

20. Limitation of Liability. Notwithstanding anything to the contrary contained in this Lease, the liability of Landlord (and of any successor
Landlord) to Tenant (or any person or entity claiming by, through or under Tenant) shall be limited to the interest of Landlord in the Premises. Tenant shall look solely to Landlord’s interest in the Premises for the recovery of any judgment or
award against Landlord. No Landlord Party shall be personally liable for any judgment or deficiency. Before filing suit for an alleged default by Landlord, Tenant shall give Landlord and the Mortgagee(s) whom Tenant has been notified hold Mortgages
affecting the Premises, notice and reasonable time to cure the alleged default. Tenant hereby waives all claims against all Landlord Parties for consequential, special or punitive damages. No Tenant Party shall be personally liable for any judgment
or deficiency. Landlord hereby waives all claims against all Tenant Parties for consequential, special or punitive damages. 
 21.
Tenant’s Right to Possession. Provided Tenant is not in Default, Tenant shall have the right to occupy the Premises without hindrance from Landlord or any person lawfully claiming through Landlord,
subject to the terms of this Lease, all Mortgages, insurance requirements and applicable Law and Regulations. This covenant and all other covenants of Landlord shall be binding upon Landlord and its successors only during its or their respective
periods of ownership of the Premises during the Term. 
 22. Landlord’s Default and
Tenant’s Remedies. In the event of any default in any obligation of Landlord under this Lease, Tenant will deliver written notice to Landlord listing the reasons for Landlord’s default and Landlord will
have 30 days following receipt of such written notice to cure such default (or a reasonable period of time not to exceed a total of 90 days if such default is not curable within such 30-day period). A copy of
such notice will be sent to any Landlord’s Mortgagee of which Tenant has been notified in writing and any such holder will have the same 

  
 14 

 *** Certain confidential portions (indicated by brackets and asterisks) have been omitted from this
exhibit because such information is both (i) non-material and (ii) would be competitively harmful if publicly disclosed. 
  

 
rights as Landlord hereunder to cure such alleged default; provided, however, that any such Landlord’s Mortgagee shall have an additional 30 days beyond the time periods set forth above to
effect any such cure. It shall be an automatic default by Landlord if the interest of Landlord in and to any portion of the Premises is levied on under execution or other legal process, or any petition is filed by or against Landlord to declare
Landlord a bankrupt or to delay, reduce or modify Landlord’s debt or obligations and the same is not dismissed within 90 days after the date of such filing, or if Landlord is declared insolvent according to law, or any general assignment or
Landlord’s property is made for the benefit of creditors, or a receiver or trustee is appointed for Landlord or its property. The payment by Tenant of Fixed Rent hereunder shall not be deemed to be a waiver of any breach or default at the time
of payment of Fixed Rent. If Landlord fails to cure a default, then Tenant may, at Tenant’s option cure the default or pursue any other rights of remedies available to Tenant under this Lease, at law or in equity. Landlord shall reimburse
Tenant for any sums expended by Tenant to cure a Landlord default. 
 23. Holding Over. If Tenant or any other party fails to surrender the
Premises at the expiration or earlier termination of this Lease, the continued occupancy of the Premises shall be that of a tenancy at sufferance. No holdover by Tenant or payment by Tenant after the expiration or early termination of this Lease
shall be construed to extend the Term. 
 24. Subordination to Mortgages; Financial Statements; Estoppel Certificates. Subject to this
Section 24, Tenant accepts this Lease subject and subordinate to any mortgage(s) or deed(s) of trust now or subsequently affecting the Site, and to renewals, modifications, refinancings and extensions thereof (collectively,
a “Mortgage”). The party having the benefit of a Mortgage shall be referred to as a “Mortgagee.” Upon request from a Mortgagee, Tenant shall execute a commercially reasonable subordination, non-disturbance and attornment agreement in favor of the Mortgagee, which shall also provide for notice to Mortgagee of any default or potential termination of this Lease and a reasonable opportunity to cure any
default without obligation to do so. In lieu of having the Mortgage be superior to this Lease, a Mortgagee shall have the right at any time to subordinate its Mortgage to this Lease. If requested by a successor-in-interest to all or a part of Landlord’s interest in this Lease, Tenant shall, without charge, attorn to the
successor-in-interest; provided, such successor in interest assumes Landlord’s obligation under this Lease. Tenant shall, within 15 Business Days after receipt of a
written request from Landlord, execute and deliver to Landlord and/or its designee an estoppel certificate to those parties as are reasonably requested by Landlord, certifying to Landlord and/or a Mortgagee and/or a prospective purchaser of the Site
such facts and agreeing to such reasonable notice provisions as reasonably requested by Landlord, subject to appropriate factual modifications. Tenant’s failure to provide any estoppel certificate within the 15 Business Day period specified
above, and the continuation of such failure for a period of 5 Business Days after Landlord delivers a second written notice requesting same, shall constitute a Time Sensitive Default under this Lease. 

25. Attorneys’ Fees. The prevailing party in any legal proceeding based on this Lease may recover reasonable
attorneys’ fees, investigation costs, and other costs incurred in connection with such legal proceeding from the non-prevailing party in addition to any other relief to which such prevailing party is
entitled. The term “prevailing party” shall mean that party which the court finds and/or declares is the prevailing party, whether or not that party obtains monetary, declaratory, injunctive, equitable or nominal relief. With
respect to any monetary claim, no award of damages shall be necessary in order for a party to be found by the court to have prevailed. With respect to any non-monetary claim, no equitable relief shall be
necessary in order for a party to be found by the court to have prevailed.

 26. Notice. Any demand, request, approval, consent or notice (collectively, a
“notice”) may be given by either party or its attorney or agent and shall be in writing and delivered (a) by hand, (b) by nationally recognized overnight air courier services (such as Federal Express), (c) by United
States Postal Service, registered or certified mail, return receipt requested or (d) by electronic mail, in each case addressed to the respective party at the address set forth below or such other address as designated in writing by either
party.

computer, satellite or telecommunications equipment or hardware; provided, however, if Tenant fails to complete such removal within 90 days after Landlord’s delivery of any such notice, Landlord may perform such removal on Tenant’s behalf,

 28. Hazardous Materials. 

(a) Restrictions. No Hazardous Material (defined below) (except for de minimis quantities of household cleaning
products and office supplies used in the ordinary course of Tenant’s business at the Premises and that are used, kept and disposed of in compliance with Laws) shall be brought upon, used, kept or disposed of in or about the Site by any Tenant
Parties or any of Tenant’s transferees, contractors or licensees. Tenant agrees to indemnify, defend and hold Landlord and its officers, partners, directors, shareholders, employees and agents harmless from any claims, judgments, damages,
fines, penalties, reasonable costs, liabilities (including sums paid in settlement of claims) or loss including reasonable attorneys’ fees, consultants’ fees, and expert fees which arise during or after the Term of this Lease in connection
with the presence or suspected presence of Hazardous Material in the soil, groundwater, or soil vapor on or under the Site caused by the acts or omissions of Tenant, its officers, employees or agents. Landlord shall not (and shall not permit its
agents, contractors or employees to) use, generate, store, or dispose of Hazardous Materials at the Premises, except in a manner and quantity necessary for the operation of the Property and/or Facility and then in compliance with all applicable
Laws. Notwithstanding the foregoing, Tenant shall not have any liability to or any obligation to indemnify Landlord or any Landlord Party for any Hazardous Material at the Premises which existed prior to the Delivery Date or any Contamination not
caused or exacerbated by Tenant or any Tenant Party, all of which shall be Landlord’s obligation. Landlord represents and warrants to Tenant that, to Landlord’s actual knowledge as of the Effective Date, the Premises are free from
contamination from any reportable quantities of Hazardous Materials and is not in violation in any material respect of any environmental Law pertaining to Hazardous Materials. 

(b) Remediation. Tenant shall promptly notify Landlord if it suspects Contamination in the Premises. Any remediation of
Contamination caused by a Tenant Party or its contractors or invitees which is required by Law or which is deemed necessary by Landlord, in Landlord’s reasonable opinion, shall be performed by Landlord and Tenant shall reimburse Landlord for
the reasonable, actual cost incurred by Landlord in connection therewith. For purposes of this Lease, “Remediation” means any investigation, sampling, analysis, monitoring, removal, remediation, cleanup,
treatment, storage, disposal or other action in order to comply with Laws pertaining to Contamination. 
 29. Miscellaneous. 

(a) Governing Law; Jurisdiction and Venue; Severability; Paragraph Headings. This Lease shall be interpreted, construed and
enforced in accordance with the Laws of the state in which the Site is located. All obligations under this Lease are performable in the county or other jurisdiction where the Site is located, which shall be venue for all legal actions. If any term
or provision of this Lease shall be invalid or unenforceable, then such term or provision shall be automatically reformed to the extent necessary to render such term or provision enforceable, without the necessity of execution of any amendment or
new document, the remainder of this Lease shall not be affected, and each remaining and reformed provision of this Lease shall be valid and enforced to the fullest extent permitted by Law. The headings and titles to the Sections of this Lease are
for convenience only and shall have no effect on the interpretation of any part of this Lease. The words “include”, “including” and similar words will not be construed restrictively to limit or exclude other items not listed.

 *** Certain confidential portions (indicated by brackets and asterisks) have been omitted from this
exhibit because such information is both (i) non-material and (ii) would be competitively harmful if publicly disclosed. 
  

 (b) Recording. Tenant shall not record this Lease but may record a memorandum
of this Lease upon Landlord’s prior written approval of the form of such memorandum, such approval not to be unreasonably withheld, conditioned or delayed. SNDAs may also be recorded subject to Landlord’s foregoing approval rights. 

(c) Force Majeure. Whenever a period of time is prescribed for the taking of an action by Landlord or Tenant, the period of time
for the performance of such action shall be extended by the number of days that the performance is actually delayed due to strikes, acts of God, shortages of labor or materials, war, terrorist attacks, civil disturbances and other causes beyond the
reasonable control of the performing party. However, events of force majeure shall not extend any period of time for the payment of Fixed Rent or other sums payable by either party or any period of time for the written exercise of an option or right
by either party. 
 (d) Transferability; Release of Landlord. Landlord shall have the right to transfer and assign, in whole or
in part, all of its rights and obligations under this Lease arising hereunder after the date of the transfer and in the Facility and/or Site, and upon such transfer Landlord shall be released from any further obligations hereunder (provided such
transferee assumes all of Landlord’s obligations hereunder, including any obligations of Landlord arising prior to the date of such transfer), and Tenant agrees to look solely to the successor in interest of Landlord for the performance of such
obligations. 
 (e) Brokers. Tenant and Landlord each warrant and represent that it has not dealt with any broker or agent in
connection with the negotiation or execution of this Lease. Tenant and Landlord shall each indemnify the other against all costs, expenses, reasonable attorneys’ fees, liens and other liability for commissions or other compensation claimed by
any broker or agent claiming the same by, through or under the indemnifying party. 
 (f) Authority; Joint and Several
Liability. Tenant covenants, warrants and represents that each individual executing, attesting and/or delivering this Lease on behalf of Tenant is authorized to do so on behalf of Tenant, this Lease is binding upon and enforceable against
Tenant; and Tenant is duly organized and legally existing in the state of its organization and is qualified to do business in the state in which the Premises are located. If there is more than one Tenant, or if Tenant is comprised of more than one
party or entity, the obligations imposed upon Tenant shall be joint and several obligations of all the parties and entities. Notices, payments and agreements given or made by, with or to any one person or entity shall be deemed to have been given or
made by, with and to all of them. 
 (g) Time is of the Essence; Relationship; Successors and Assigns. Time is of the essence
with respect to each party’s performance of its obligations and the exercise of any expansion, renewal or extension rights or other options granted to Tenant. This Lease and the covenants and conditions in this Lease shall inure only to the
benefit of and be binding only upon Landlord and Tenant and their permitted successors and assigns. 
 (h) Survival of
Obligations. The expiration of the Term, whether by lapse of time or otherwise, shall not relieve either party of any obligations which accrued prior to or which may continue to accrue after the expiration or early termination of this Lease.
Without limiting the scope of the prior sentence, it is agreed that Tenant’s obligations under Sections 4, 6-8, 13, 19, 20, 23, 25, 27-28 and
29(e) and Landlord’s obligations under Sections 6, 8, 13, 20, 22, 25, 28, and 29(e) shall survive the expiration or early termination of this Lease.

 Exhibit E 

Work Letter 
 This Work
Letter is attached as an Exhibit to a Lease Agreement (the “Lease”) between [***], as Landlord, and Cipher Mining Technologies, Inc., as Tenant, for the Premises. Unless otherwise specified, all capitalized terms used in this
Work Letter shall have the same meanings as in the Lease. In the event of any conflict between the Lease and this Work Letter, the latter shall control. 

1. Construction. Tenant agrees to install certain Tenant Improvements in a good and workmanlike manner in and upon the Premises, at Tenant’s
sole cost and expense, in accordance with the following provisions. Within four (4) months after the Effective Date, Tenant shall submit to Landlord for Landlord’s approval (not to be unreasonably withheld) complete plans and
specifications for the installation of the Tenant Improvements (“Tenant’s Plans”). Within 10 Business Days after receipt of Tenant’s Plans, Landlord shall review and either approve or disapprove Tenant’s Plans.
If Landlord disapproves Tenant’s Plans, or any portion thereof, Landlord shall notify Tenant thereof and of the revisions Landlord requires before Landlord will approve Tenant’s Plans. Within 10 Business Days after Landlord’s notice,
Tenant shall submit to Landlord, for Landlord’s review and approval, plans and specifications incorporating the required revisions. The final plans and specifications approved by Landlord are hereinafter referred to as the “Approved
Construction Documents”. Tenant will employ experienced, licensed contractors, architects, engineers and other consultants, approved by Landlord, to install the Tenant Improvements and will require in the applicable contracts that such
parties (a) carry insurance in such amounts and types of coverages as are reasonably required by Landlord, and (b) design and install the Tenant Improvements in a good and workmanlike manner and in compliance with all Laws. Unless
otherwise agreed to in writing by Landlord and Tenant, all work involved in the construction and installation of the Tenant Improvements shall be carried out by Tenant’s contractors under the sole direction of Tenant, in compliance with all
Laws and Regulations and in such a manner so as not to unreasonably interfere with or disturb the operations, business and use and enjoyment of the Property by Landlord or the structural calculations for imposed loads. Tenant shall obtain from its
contractors and provide to Landlord a list of all subcontractors providing labor or materials in connection with any portion of the Tenant Improvements prior to commencement of the installation of the Tenant Improvements. Tenant warrants that the
design, construction and installation of the Tenant Improvements shall conform to the requirements of all applicable Laws, including building, plumbing and electrical codes and the requirements of any authority having jurisdiction over, or with
respect to, such Tenant Improvements. Landlord’s failure to provide Landlord’s approval or disapproval of Tenant’s Plans or the applicable revision thereof by the time specified in this section shall be deemed Landlord’s approval
of Tenant’s Plans or applicable revision thereof. 
 2. Costs. Tenant shall pay all costs for the Tenant Improvements and Tenant agrees to
keep the Premises and the Property free from any liens arising out of the non-payment of such costs. All installations and improvements now or hereafter placed in the Premises by Tenant or at Tenant’s
request shall be for Tenant’s account and at Tenant’s cost. Tenant’s failure to pay such cost shall constitute an event of default under this Lease.

subject to oversight and coordination by Landlord, but such oversight and coordination shall not subject Landlord to any liability to Tenant, Tenant’s contractors or any other person. Landlord has the right to inspect installation of the Tenant
Improvements from time to time. 
 4. Assumption of Risk and Waiver. Tenant hereby assumes any and all risks involved with respect to the
Tenant Improvements and hereby releases and discharges all Landlord Parties from any and all liability or loss, damage or injury suffered or incurred by Tenant or third parties in any way arising out of or in connection with the Tenant Improvements.

(b) Employers’ Liability Insurance with limits no less than (i) $500,000 bodily injury by accident, (ii) $500,000 bodily injury by disease

Tenant shall use commercially reasonable efforts to ensure that any permitted subcontractors hereunder carry and maintain, during the Term of
this Lease adequate insurance types and limits for the work performed under this Lease. 
 2. The foregoing required limits of insurance can
be satisfied by any combination of primary and excess coverage. Tenant’s and subcontractors’ insurance shall be primary and non-contributory regardless of the insurance available to Landlord. All
required coverages, if written on a claims-made basis, will be maintained in full force and effect for three (3) years after completion of work or termination of this Lease, whichever is later. All policies must be issued by carriers having an
A.M. Best’s rating of “A-” or better, and an A.M. Best’s financial size category of “VIII” or better, or Standard & Poor Insurance Solvency Review of “A-” or better. On or prior to the Effective Date, and on or prior to each annual anniversary of the Effective Date, Tenant shall provide to Landlord an insurance certificate evidencing such required
insurance coverage as described above. Certificates of insurance must show Vistra Corp. and its subsidiaries (including Landlord) as the certificate holder, and as an additional insured (including on-going and
completed operations) with respect to all of the required coverages except workers’ compensation. All of the required coverages must provide a waiver of subrogation in favor of the certificate holder. The requirements contained herein as to the
types and limits of all insurance to be maintained by Tenant are not intended to and will not, in any manner, limit or qualify the liabilities and obligations assumed by Tenant under this Lease.

 Exhibit G 

Landlord’s On-Site Terms and Conditions 

 

	1.	 SAFETY 

 

	1.1	 Tenant agrees that any safety-related assistance or initiatives
undertaken by Landlord will not relieve Tenant, while on Landlord’s property, from responsibility for the implementation of, and compliance with, safe working practices, as developed from their own experience, or as imposed by law or
regulation, and will not in any way, affect the responsibilities resting with Tenant under the provisions of any agreement to which these policies are attached and to meet all safety requirements as specified by the Occupational Safety &
Health Administration (OSHA), the Mine Safety Health Administration (MSHA), including the “Mining Tenant Safety Reference Handbook” located at http://www.vistraenergy.com/wp-content/uploads/2016/12/Tenants-Safety-Handbook_Final-MC-08262016.pdf, the Department of Transportation (DOT) and any other applicable state or federal safety and
health laws or regulations. 

  

	1.2	 In the event that a material safety data sheet, warning label, or other documentation concerning the use of
hazardous chemicals at any property owned or controlled by Landlord or any of its Affiliates (individually, a “Landlord Property” and collectively, “Landlord Properties”), applies to any materials or
equipment provided by Tenant as an aspect of the performance of the Permitted Use (the “Work”), such documentation will be provided by Tenant to Landlord prior to the commencement of any such Work. 

 

	1.3	 Tenant will report to Landlord all accidents involving personal injuries (including death) and damage to
property occurring directly or indirectly as a result of the Work performed by Tenant hereunder immediately, but in no event, no later than 24 hours after the occurrence of any such accident. Any accident or incident occurring directly or indirectly
as a result of the Work which Tenant must report to a regulatory agency (e.g. OSHA, MSHA, TCEQ) must also be reported to Landlord immediately following notification to the regulatory agency. 

 

	2.	 SECURITY 

  

	 	2.1	 It will be the affirmative duty of Tenant to ensure that all Tenant Parties assist in carrying out all security
measures, to include reporting all information or knowledge of matters adversely affecting security to Landlord’s designated security personnel. 

  

	 	2.2	 Landlord reserves the right to exclude any of Tenant’s employees from any Landlord Property by denial of
access, suspension or revocation of access authorization, preemptory expulsion, or by any other means, without notice or cause. Former Landlord employees, and any of Tenant’s employees who previously have been excluded from any Landlord
Property, may be brought onto a Landlord Property only if prior approval from Landlord is obtained. If Tenant terminates a Tenant Party performing Work on any Landlord Property, Tenant shall inform Landlord immediately, but in no event, no later
than twenty-four (24) hours after such employee is terminated in order for Landlord to remove access to Landlord Property for such employee. 

  
 Exhibit G – Page 1

 *** Certain confidential portions (indicated by brackets and asterisks) have been omitted from this
exhibit because such information is both (i) non-material and (ii) would be competitively harmful if publicly disclosed. 
  

	 	2.3	 Landlord measures may also include investigations, whether by Landlord or law enforcement officials. Tenant
agrees to cooperate in such investigations and understands that Landlord reserves the right to require any Tenant Party to authorize appropriate agencies to release his or her criminal records to Tenant as a condition of either initial or continued
permission for access to any Landlord Property. Investigations may include searches of any Tenant Party. Such searches may include searches of facilities assigned to such Tenant Party, search of all Landlord Property areas and property at such
Landlord Property areas, searches of including, but not limited to, offices, lockers, desks, lunch boxes, packages and motor vehicles (regardless of ownership). Without limiting the foregoing, Tenant acknowledges and agrees that all Tenant Parties,
to the extent that Landlord reasonably determines that such members require security badge access prior to entering onto any Landlord Property, shall be required to comply with Landlord’s standard security badge requirements, including without
limitation a background check to be performed by Landlord. 

  

	 	2.4	 Tenant personnel will abide by all NERC CIP regulatory requirements that Landlord deems applicable including,
but not limited to; current NERC CIP regulations (CIP-003-7), transient cyber assets and removable media requirements, completion of CIP training and awareness
practices, adherence to facility security plan, and electronic access controls. 

  

	 	2.5	 Tenant will alert Landlord of any cyber security incidents with assets
on-site immediately; but in no event, later than 24 hours after occurrence of any such incident. 

  

	3.	 ISNETWORLD 

  

	 	3.1	 Tenant agrees to maintain at Tenant’s expense a subscription with ISNetworld (www.ISNetworld.com),
Landlord’s safety compliance program or any replacement program therefor, as directed by Landlord, for the Term of the Lease. Tenant shall also furnish ISNetworld with any information requested by ISNetworld relating to ISNetworld’s
evaluation of the Tenant’s safety program and practices. As a minimum, requested documents will be related to safety, health, and insurance (i.e., regulatory required training, certifications, safety plans, safe and secure workplace practices,
insurance certificates, etc.), OSHA and MSHA injury rates and Experience Modification Rate (EMR). 

  

	 	3.2	 Tenant has and during the Term of the Lease shall continue to report full, complete and accurate information to
ISNetworld concerning Tenant’s employees. 

  

	4.	 MATERIALS, EQUIPMENT AND LABOR. Tenant will be solely responsible for the proper storage, transportation
and disposal of any product or waste, other than sandblasting waste, used or generated in connection with the Work in accordance with all applicable environmental laws. Tenant will dispose of all waste materials, other than sandblasting waste, at an
off-site disposal facility approved for such waste materials pursuant to applicable environmental laws and will complete and sign all waste manifests as the generator of such waste. Landlord will be
responsible for the storage, transportation and disposal of any sandblasting waste generated during the performance of the Work. 

  
 Exhibit G – Page 2

exhibit because such information is both (i) non-material and (ii) would be competitively harmful if publicly disclosed. 
  

	5.	 CONDITIONS AFFECTING WORK 

 

	 	5.1	 Tenant will investigate and acquaint itself with the conditions affecting the Work, including but not limited
to those related to the transportation, disposal, handling and storage of materials and waste; availability of labor, water, electric power and roads; the uncertainties of weather, river stages or similar physical conditions at the site; the
conformation and condition of the ground; and the character of equipment and facilities needed preliminary to and during prosecution of the Work. Tenant has satisfied itself as to the character, quality and quantity of surface and subsurface
materials or obstacles to be encountered. Tenant’s failure to acquaint itself with any conditions affecting the Work or any available related information will not relieve it from responsibility for properly estimating the difficulty or cost of
successfully performing the Work. 

  

	 	5.2	 Tenant assumes full responsibility for investigating conditions and determining the existence and magnitude of
any hazards to the physical well-being of property of Tenant, the employees, agents, and servants of Tenant, or any other person or entity who is or may become involved in the performance of Work, and any and all other persons in the vicinity of the
Work. Tenant will advise all of the above-specified persons or entities of any hazards relating to Work, and will ensure that those persons or entities are advised of and fully understand the nature of the hazards and safety precautions that can be
taken to eliminate or minimize dangers relating to the hazards. 

  

	 	5.3	 Tenant will provide information to Landlord regarding hazardous chemicals and/or consumable products that
contain constituents listed in 40 CFR 372.65 used at any Landlord Property. Tenant will report the amount of such material carried on and off the site, the amount actually used and the manner of use. Tenant will provide the maximum quantity of the
material stored on site at any one time and if a waste material was collected, where it was disposed of (location name and address). Tenant will provide information on the amount of material used for the previous calendar year by the first of
February. 

  

	 	5.4	 Tenant will use its best efforts to ensure that the Work is performed so as to minimize any adverse impact upon
natural resources and the environment and will use best industry practices in this regard at all times. 

  

	 	5.5	 Tenant acknowledges and agrees that all Tenant Parties performing Work at any Landlord Generation or Mining
Property are required to view Landlord’s “Contractor/Visitor Safety Orientation” video (in the case of Landlord Generation property), when applicable, and to read and adhere to Landlord’s “Contractor/Visitor Safety
Booklet” (in the case of Landlord Mining property) prior to performing any Work at any Landlord Generation or Mining Property.

exhibit because such information is both (i) non-material and (ii) would be competitively harmful if publicly disclosed. 
  

	 	5.6	 Tenant will immediately notify Landlord as soon as Tenant has reason to believe that Tenant, or any Tenant
Party, is not or may not be performing the Work in compliance with applicable Environmental Laws. Tenant will provide Landlord with written notice to Landlord of such actual or potential non-compliance within
three (3) days following the discovery thereof. Tenant will take immediate steps to ensure compliance with all applicable Environmental Laws and will, if directed by Landlord, cease all Work until authorized by Landlord to resume the Work.

  

	 	5.7	 Tenant will report to Landlord all accidents involving personal injuries (including death) and damage to
property occurring directly or indirectly as a result of the Work performed by Tenant hereunder immediately, but in no event, no later than 24 hours after the occurrence of any such accident. Any accident or incident occurring directly or indirectly
as a result of the Work which Tenant must report to a regulatory agency (e.g. OSHA, MSHA, TCEQ) must also be reported to Landlord immediately following notification to the regulatory agency. 

 

	6.	 PREMISES PERMITS AND LICENSES 

 

	 	6.1	 Subject to the following two paragraphs, Tenant will obtain, prior to the commencement of the Work, and provide
to Landlord upon request, all permits, licenses and governmental authorizations, at its sole expense, required for the performance of the Work. Tenant will be solely responsible for maintaining compliance with such permits, licenses and governmental
authorizations. 

  

	 	6.2	 In the event that a storm water discharge permit is required for the performance of the Work, (i) Tenant
will be responsible for filing a Notice of Intent with respect to the Work, in addition to any Notice of Intent that Landlord may be required to file, and (ii) Tenant will coordinate with Landlord in the preparation and execution of a Storm
Water Pollution Prevention Plan for the Premises. 

  

	 	6.3	 In the event that the performance of the Work involves the handling or abatement of asbestos-containing
materials, Tenant will coordinate with Landlord in the preparation and filing of all required notification forms. 

  

	7.	 RESERVED.  

  

	8.	 LANDLORD FACILITIES. Tenant will not use Landlord’s sanitary facilities, changehouses, shops,
parks, storage buildings, tools, equipment or other facilities (excluding the Access Areas) unless so directed by Landlord. 

  

	9.	 ENVIRONMENTAL 

 

	 	9.1	 In the event that Tenant discovers during the performance of the Work any substance at the Premises that is not
the subject of the Work or has not otherwise been identified by Landlord for Tenant, which substance Tenant has reason to believe is or may be a Hazardous Substance that (i) has been or may be released or spilled into the soil, surface water,
or groundwater or in a building or structure, or (ii) consists of asbestos-containing materials, lead-based paint, batteries, thermostats, lighting equipment, or equipment containing polychlorinated biphenyls, Tenant will immediately stop Work
and notify Landlord of the discovery. Tenant will not resume the Work until receiving authorization from Landlord to do so. 

  
 Exhibit G – Page 4

 *** Certain confidential portions (indicated by brackets and asterisks) have been omitted from this
exhibit because such information is both (i) non-material and (ii) would be competitively harmful if publicly disclosed. 
  

	 	9.2	 The term “Hazardous Substance” means any product, waste, emission or substance defined, listed
or designated as a hazardous or toxic substance, hazardous waste, hazardous material or pollutant by or pursuant to any Environmental Law and includes, but is not limited to, any petroleum-based product, substance or waste, including any additives
