AMENDED AND RESTATED RECOGNITION AGREEMENT

THIS AMENDED AND RESTATED RECOGNITION AGREEMENT (this “Agreement”) is made and entered into as of this 20th day of November, 2025 (being the latest of the parties’ dates of execution; the “Effective Date”), by and among Cipher Barber Lake LLC, a Delaware limited liability company (“Landlord”), Fluidstack USA II Inc., a Delaware corporation (“Fluidstack”), and Google LLC, a Delaware limited liability company (“Google”).

RECITALS

A. Landlord is the owner of certain real property located in Colorado City, Mitchell County, Texas, consisting of approximately 250 acres (as depicted in Schedule A attached hereto and made a part hereof, collectively, the “Property”).

B. Landlord and Fluidstack entered into that certain Datacenter Lease, dated September 24, 2025 (the “Prior Fluidstack Lease”) and Landlord, Fluidstack and Google entered into that certain Recognition Agreement, dated September 24, 2025, as amended by that certain side letter, dated November 13, 2025, relating thereto (the “Prior Google RA”).

C. Landlord and Fluidstack have agreed to amend and restate in its entirety the Prior Fluidstack Lease and enter into that certain Amended and Restated Datacenter Lease dated as of the Effective Date (attached hereto as Schedule B, as amended and restated from time to time, the “Fluidstack Lease”), pursuant to which Fluidstack is the tenant of Landlord and Landlord leases to Fluidstack the Tenant Space, as defined therein.

D. Google wishes to obtain from Landlord certain assurances that Google will have the option to assume the Fluidstack Lease and that, in such event, the enforcement of Landlord’s rights against Fluidstack shall affect Google to the least extent possible.

E. In connection with the execution of the Fluidstack Lease, the parties hereto wish to amend, restate, supersede and replace in its entirety the Prior Google RA as set forth herein.

F. Landlord is willing to provide such assurances to Google upon and subject to the terms and conditions of this Agreement.

AGREEMENT

NOW, THEREFORE, which are hereby acknowledged, the parties hereto do mutually agree as follows:

1. Definitions. Capitalized terms not otherwise defined herein shall have the meaning given to such terms in the Fluidstack Lease, as the context may require.

2. Confirmation Regarding Fluidstack Lease; Google Property.

a. Landlord acknowledges, agrees and represents to the other parties on the Effective Date (a) that the Fluidstack Lease is legal, valid and binding against Landlord and Fluidstack, and in full force and effect, and (b) to the knowledge of Landlord, on the date hereof, there are no events that do presently, or which may, with the passage of time, the giving

of notice, or the expiration of a period of grace, constitute a breach or default by either party under the Fluidstack Lease. Fluidstack acknowledges, agrees and represents to the other parties on the Effective Date (a) that the Fluidstack Lease is legal, valid and binding against Landlord and Fluidstack, and in full force and effect, and (b) to the knowledge of Fluidstack, on the date hereof, there are no events that do presently, or which may, with the passage of time, the giving of notice, or the expiration of a period of grace, constitute a breach or default by either party under the Fluidstack Lease.

b. Landlord and Fluidstack acknowledge and agree that if Tenant’s Personal Property under the Fluidstack Lease includes any Google Property (as defined below) and such Google Property is lost or damaged while in the Tenant Space, then Google will be a third party beneficiary of the provisions of the Fluidstack Lease that relate to Landlord’s obligations with respect to such loss or damage of such Google Property, subject to the rights and limitations with respect to such obligations as set forth in the Fluidstack Lease. “Google Property” means equipment or property owned by Google (or its affiliate) that is located in the Tenant Space as shown by reasonable documentary evidence provided by Google.

c. If there is any Google Property remaining in the Tenant Space upon expiration or termination of the Fluidstack Lease, (i) Landlord will provide Google access to the Tenant Space and the Google Property in accordance with, and subject to, the holdover provisions in the Fluidstack Lease applicable to Tenant’s Personal Property to allow Google to remove the Google Property from the Tenant Space, (ii) the Term of the Fluidstack Lease will be automatically extended for a Transition Period as described therein (the length of such period to be defined by Google, but not to exceed 120 days), and (iii) Google agrees to pay all Rent for the Transition Period; provided that, in the event such termination (or deemed termination) is the result of an Event of Default by Fluidstack under the Fluidstack Lease, or if any Colocation Agreement is then in effect (including pursuant to any holdover or transition period described in such Colocation Agreement), Fluidstack shall pay all such Rent. Notwithstanding the foregoing, Landlord agrees that no Rent will be payable for the Transition Period if termination of the Fluidstack Lease is pursuant to Google’s election (or deemed election) of the Google Rejection Option as described below. For the avoidance of doubt, this Section 2.c. will not be applicable in connection with the execution of the Novation Agreement pursuant to the Google Assumption Option as described below.

d. Fluidstack acknowledges and agrees that it is responsible to Google for the protection of any Google Property in the Tenant Space and if any such Google Property is lost or damaged by the acts or omissions of Fluidstack’s Personnel (as defined below), Fluidstack will reimburse Google for the replacement cost of such Google Property lost or damaged. For the avoidance of doubt, Fluidstack shall have no liability to Google for any damage or loss to any Google Property in the Tenant Space to the extent such damage or loss was caused by the acts or omissions of Google’s or any third party’s Personnel. “Personnel” means all employees and agents of a party and its subcontractors and agents.

e. Whereas Fluidstack (or its affiliate) is a party to a certain Site Access Agreement with certain Colocation Parties executed on or around the Effective Date of this Agreement (“Access Agreement”), in the event that the ownership of any equipment thereunder is transferred by sale to Google thus becoming Google Property, Fluidstack will grant (or will cause its affiliate to grant) to Google access to the Tenant Space and such equipment for a period of four (4) months from the date of Google’s purchase of the equipment,

-2-

to allow Google to remove the equipment from the Tenant Space. During such period, Fluidstack will not deem the equipment to be abandoned, notwithstanding anything to the contrary in any Colocation Agreement underlying the Access Agreement. For the avoidance of doubt, the parties acknowledge and agree that (i) Fluidstack’s rights and obligations with respect to Tenant’s Personal Property are governed by the Fluidstack Lease, and this Section 2(e) does not affect the terms of the Fluidstack Lease with respect thereto and (ii) neither Google nor Landlord is a party to or subject to the terms of the Access Agreement.

3. Right to Cure Default.

a. Landlord will not seek to terminate the Fluidstack Lease by reason of any act or omission that constitutes (or would over time constitute) a default by Fluidstack under such Fluidstack Lease, until Landlord shall have given written notice of such act or omission to Google (as required under the Fluidstack Lease, Item 3 of the Basic Lease Information); and Google shall have the right, but not the obligation, to remedy such act or omission on Fluidstack’s behalf, subject to the time periods in Section 15.1 (Events of Default By Tenant) of the Fluidstack Lease, except with respect to any failure or refusal by Tenant to timely pay any Rent or any other payments or charges required to be paid thereunder, it shall not constitute an Event of Default by Tenant under Section 15.1.1 of the Fluidstack Lease if Google gives written notice to Landlord of its intent to remedy such failure or refusal no later than the fifteenth (15^th) day after Google’s receipt of the default notice and thereafter pays such Rent or other payments or charges properly due and owing no later than the thirtieth (30^th) day after receipt of a correct, itemized invoice from Landlord. Landlord agrees that it will accept such performance by Google of any covenant, condition or agreement to be performed by Fluidstack under the Fluidstack Lease with the same force and effect as though performed by Fluidstack. The provisions of this Section 3 shall not be construed as obligating Google to cure any breach or default by Fluidstack under the Fluidstack Lease. Except as provided in this Section 3 and Section 4, below, nothing in this Agreement is intended to suspend or otherwise limit Landlord’s ability to exercise any other rights and remedies that Landlord may have against Fluidstack as a result of such breach or default. Any invoices submitted under this Agreement must be submitted through Google’s vendor management system.

b. Landlord represents and warrants that it owns all right, title and interest in and to the Building free and clear of all liens, encumbrances and defects, other than (i) pursuant to the indenture dated as of November 13, 2025 (the “Indenture”) by and among Cipher Compute LLC, Cipher Songbird LLC and Landlord and the Collateral Documents (as such term is defined in the Indenture) relating to the Indenture, (ii) incremental debt financing in an aggregate principal amount of approximately $333.0 million, which may be issued and incurred as “additional notes” under the Indenture, (iii) the Security Documents as described in the Fluidstack Lease or (iv) as specifically described in Schedule H hereto.

4. Google Options Related to FS Event of Default.

a. FS Default Trigger. In the event that (i) Fluidstack has become subject to an Insolvency Event or (ii) an Event of Default under Section 15.1.1 of the Fluidstack Lease has occurred (the occurrence of (i) or (ii), the “FS Default Trigger”), Landlord will immediately provide Google written notice that the FS Default Trigger has occurred. An “Insolvency Event” is the occurrence of an event identified in Section 15.1.3 of the Fluidstack Lease. Thereupon, Landlord and Google will have a period of 90 days to identify and mutually agree upon (via a signed written amendment) a tenant to assume the Fluidstack Lease as the

-3-

Tenant thereunder and this Agreement in place of Fluidstack (subject to such replacement tenant entering into one or more separate agreements with Google which are deemed necessary by Google) (the foregoing process for potentially identifying and mutually agreeing upon a tenant to assume the Fluidstack Lease, the “New Tenant Process”). If Landlord and Google mutually agree upon such a tenant, such tenant shall be liable for the Rent owed under the Fluidstack Lease during such ninety (90)-day period. If Landlord and Google are unable to mutually agree upon such a tenant within such ninety (90)-day period, Landlord will provide Google written notice of the same (the “Google Default Notice”) and Google shall be liable for the Rent owed under the Fluidstack Lease during such ninety (90)-day period, but notwithstanding anything to the contrary in this Agreement the Rent for such ninety (90)-day period will be: (i) with respect to the Phase I Areas, calculated based on the lesser of: (A) the Base Rent for Phase I as set forth in the Lease applicable to the Existing Tenant or (B) the Discounted Rent as described in Section 1.1(c)(ii) (Modified Rent Rates for Google) of Schedule D and (ii) with respect to the Phase II Areas, the Base Rent for Phase II as set forth in the Lease applicable to the Existing Tenant. Google will have a period of 30 days after receipt of the Google Default Notice (“Verification Period”) to verify that the requirements of the FS Default Trigger have been met. Landlord and Fluidstack will timely cooperate with reasonable requests by Google for information and documentation regarding the FS Default Trigger.

Within the Verification Period, Google will have the option to elect, by written notice of the same to Landlord (the “Google Election Notice”) to either: (i) allow the Fluidstack Lease to be terminated by Landlord (the “Google Rejection Option”); or (ii) pay all Rent under the Fluidstack Lease that is then, currently, properly due and owing by Fluidstack to Landlord and assume the Fluidstack Lease as the Tenant thereunder (the “Google Assumption Option”); provided that, the Google Rejection Option will only be available if: (a) the FS Default Trigger occurs after the first six (6) years of the initial term of the Fluidstack Lease; (b) prior to the Phase II Commencement Date, the Phase I Areas (as defined under the Fluidstack Lease) have equipment installed which when in operation are capable of consuming less than 50% of the Initial Baseline Capacity; or (c) as of and following the Phase II Commencement Date, the Premises have equipment installed which when in operation are capable of consuming less than 50% of the Subsequent Baseline Capacity, and for the avoidance of doubt, if the Google Rejection Option is not available (each such conditions in clauses (b) and (c), as applicable, an “Assumption Only Condition”), then the Google Assumption Option must be elected by Google. “Initial Baseline Capacity” means [REDACTED] MW of electrical power. “Subsequent Baseline Capacity” means [REDACTED] MW of electrical power. Notwithstanding the foregoing, if an FS Default Trigger has occurred only under clause (ii) of the definition of FS Default Trigger, but no Insolvency Event has occurred, then Google will have the option (the “Deferral Option”) to elect during the Verification Period, by written notice to Landlord, to neither elect the Google Rejection Option or the Google Assumption Option, and instead defer such election until the Deferral Option End Date (as defined in Section 4.e.). If the Deferral Option is elected then, during the period from the written election of the Deferral Option until the Deferral Option End Date (such period, the “Deferral Period”), (i) the Verification Period will be deemed to toll hereunder and (ii) Section 4.e. will apply. For the avoidance of doubt, if Google has neither provided the Google Election Notice or elected the Deferral Option by written notice on or before the end of the Verification Period, Google will be deemed to have elected the Google Rejection Option (or, in the case of an Assumption Only Condition, Google will be deemed to have elected the Google Assumption Option).

-4-

b. Google Rejection Option. If Google elects (or is deemed to have elected) the Google Rejection Option, Landlord will be deemed, upon such election, to have immediately terminated the Fluidstack Lease. Within forty-five (45) days after the end of the Verification Period that results in Google having elected the Google Rejection Option, Landlord will send notice to Fluidstack and Google confirming Landlord’s termination of the Fluidstack Lease, together with a correct invoice for Google in the amount of the FS Termination Fee (as defined below) (the “Landlord Termination Notice”), provided, that the failure or delay of such notice will have no effect upon whether or when Landlord’s termination has occurred. Google will, within 15 days after the receipt of the Landlord Termination Notice (including the associated invoice), pay Landlord a termination fee (the “FS Termination Fee”). The amount of the FS Termination Fee will be an amount determined by Landlord and memorialized in the Landlord Termination Notice not to exceed the amount applicable to the date of termination according to the schedule of FS Termination Fee (the “Schedule of FS Termination Fee”) attached to this Agreement as Schedule C.

The payment of the FS Termination Fee will be made by Google directly into the Designated FS Termination Fee Account pursuant to the terms of the Google Financial Support Agreement. Upon the payment of the FS Termination Fee by Google, (a) Landlord releases and discharges Fluidstack from all liabilities and obligations under the Fluidstack Lease; provided that this clause (a) shall not affect any claim or demand that Landlord may have against Fluidstack arising before the date of the payment of the FS Termination Fee by Google (except with respect to payment of Rent under the Lease); (b) Google will have no further liabilities or obligations related to the Fluidstack Lease; (c) Google will be provided an equity interest position in Landlord equal to the quotient derived from (i) the amount of the FS Termination Fee paid by Google divided by (ii) the total cost to acquire and develop the Property and construct the Building and all other improvements consisting of and/or otherwise supporting the Tenant Space on the Property (including all land acquisition and development costs, the costs to construct the Building, the costs of all of Landlord’s equipment and infrastructure supporting the Tenant Space, all costs associated with the delivery of the Tenant Space and the Premises to Fluidstack under the Lease (including under Exhibit E thereto and with respect to Landlord’s Work (as defined under the Lease)) and all financing costs related thereto, including the costs set forth on Schedule E hereto) (such quotient, the “Google Equity Interest”); and (d) upon Google’s receipt of the Google Equity Interest, this Agreement will be deemed to have terminated. The “Google Financial Support Agreement” shall mean that certain Financial Support Agreement dated as of November 13, 2025, attached hereto as Schedule F, entered into between Google, Alphabet Inc., Landlord and Wilmington Trust, National Association, which provides that if the FS Termination Fee shall become due and payable hereunder, then Google shall be required to make such payment directly to the Designated FS Termination Fee Account in accordance with such agreement. The payment of the FS Termination Fee in accordance with the Google Financial Support Agreement will satisfy Google’s obligation to pay the FS Termination Fee hereunder. The “Designated FS Termination Fee Account” means the account identified in the Google Financial Support Agreement for the payment of the FS Termination Fee. The parties hereby acknowledge and agree that Google, Cipher Compute LLC and Wilmington Trust, National Association have entered into that certain Pledge Agreement dated as of November 13, 2025, attached hereto as Schedule G. Google shall cooperate at the cost of Landlord or Landlord’s financing sources (as applicable), with all reasonable requests by Landlord and Landlord’s financing sources in connection with Landlord’s financing arrangements, including executing and delivering any documents or instruments reasonably requested by Landlord and Landlord’s financing sources.

c. Google Assumption Option.

(1) If Google elects the Google Assumption Option (or is deemed to elect the Google Assumption Option) in accordance with this Agreement, (i) Google, Landlord, and Fluidstack must (within fifteen (15) days after Google’s provision of the Google Election Notice to Landlord) execute a novation agreement which includes the early termination provisions as described in Section 1.1(c)(i) (Google’s Early Lease Termination Right) of Schedule D, the modification of rates for Base Rent for Phase I under the Fluidstack Lease as described in Section 1.1(c)(ii) (Modified Rent Rates for Google) of Schedule D, and is otherwise substantially on the form attached hereto as Schedule D (the “Novation Agreement”), whereby Google replaces Fluidstack as the “Tenant,” and assumes all Novated Obligations of Fluidstack under the Fluidstack Lease; (ii) Google shall be liable for all Rent under the Fluidstack Lease, including the Base Rent for Phase I as described in Section 1.1(c)(ii) (Modified Rent Rates for Google) of Schedule D, as it becomes due, regardless of when (or if) the Novation Agreement is executed and delivered; and (iii) Google must pay all Rent that is then, currently, properly due and owing by Fluidstack to Landlord under the Fluidstack Lease within fifteen (15) days after the receipt of a correct, itemized invoice for such Rent from Landlord. If the Novation Agreement is not executed by Google, Landlord, and Fluidstack within the above-mentioned 15-day period, the parties will thereupon be deemed to have executed the Novation Agreement upon the expiration of the 15-day period and Google will have the right to terminate the Fluidstack Lease early as described under Section 1.1(c)(i) (Google’s Early Lease Termination Right) of Schedule D and Google’s liability for Base Rent for Phase I under the Fluidstack Lease will be limited as described in Section 1.1(c)(ii) (Modified Rent Rates for Google) of Schedule D. The “Novated Obligations” means all (x) then-unperformed obligations of Tenant to pay Rent due and owing to Landlord under the Fluidstack Lease that arose before the date of the Novation Agreement; and (y) obligations of Tenant under the Fluidstack Lease that arise on or after the date of the Novation Agreement, and specifically excluding any obligations that are not related to payment arose before the date of the Novation Agreement.

(2) Once the Novation Agreement is executed by Google, Fluidstack and Landlord, the novated Fluidstack Lease and all appurtenances thereto shall come into effect as an agreement between Landlord and Google, and Landlord shall be bound to Google under all of the provisions of the Fluidstack Lease for the balance of the term thereof (including any extensions or renewals thereof which may be effected in accordance with any options contained in the Fluidstack Lease) with Google as the “Tenant” under the Fluidstack Lease from and after the date of the Novation Agreement. In such event, Google shall attorn to Landlord as its landlord under the Fluidstack Lease, such attornment to be effective and self-operative, without the execution of any further instruments on the part of either of the parties hereto, upon and from and after the date of the Novation Agreement. If Google elects the Google Assumption Option (or is deemed to elect the Google Assumption Option), upon the execution (or deemed execution) by all parties of the Novation Agreement and Google’s satisfaction of its obligation under clause (iii) of Section 4.c.(1) of this Agreement, this Agreement shall terminate.

(3) Customer Retention Incentives. Upon the effective date of the Novation Agreement (or the date such Novation Agreement is deemed to be executed) and if any Fluidstack Strategic Customer has property remaining in the Tenant Space at such time, Google will offer such Fluidstack Strategic Customer(s) a transition period equal to the shorter of: (i) 12 months or (ii) the remainder of the initial term of the Fluidstack Lease

-6-

to access and use the Tenant Space subject to such Fluidstack Strategic Customer entering into a Transition Period Access for Potential Google Customers Agreement with Google detailing the rent fees and other terms and conditions of such access and usage (the “Transition Period Access for Potential Google Customers”). Google will offer such Fluidstack Strategic Customer commercially reasonable rent and other economic terms and conditions (provided however that Google will not charge such Fluidstack Strategic Customer for such access to the Tenant Space to the extent that Google is already receiving rent for such Tenant Space from a third-party) and other terms and conditions for such Transition Period Access for Potential Google Customers, which will include: (i) a commitment that Google will not permit mechanic’s or other liens to be placed upon such Fluidstack Strategic Customer’s equipment, (ii) a commitment that Google will be liable for loss or damage to such Fluidstack Strategic Customer’s equipment caused by the acts or omissions of Google’s Personnel, provided that such Fluidstack Strategic Customer will be liable to loss or damage to the Tenant Space caused by the acts or omissions of such Fluidstack Strategic Customer’s Personnel, (iii) a commitment that such Fluidstack Strategic Customer’s Personnel will have access as necessary to remove such Fluidstack Strategic Customer’s equipment from the Tenant Space upon reasonable notice to Google, and (iv) a commitment that such Fluidstack Strategic Customer will provide the reasonable opportunity (at Google’s option) for representatives of Google to be present at all times and such Fluidstack Strategic Customer will comply with the reasonable policies (including any security policy) and instructions of Google and/or any Google Personnel in place at the Tenant Space at the time of such access. While Google and such Fluidstack Strategic Customer are negotiating such terms and conditions for the Transition Period Access for Potential Google Customers such period of negotiation not to exceed 1 month, Google will provide, if requested, such access as necessary to remove such Fluidstack Strategic Customer’s property from the Tenant Space during such period subject to such Fluidstack Strategic Customer entering into an agreement with Google that includes subsections (i) through (iv) above. “Fluidstack Strategic Customer” means each customer of Fluidstack that had entered into a legal agreement with Fluidstack for Fluidstack to provide colocation and managed services and such services require, prior to the Phase II Commencement Date, at least [REDACTED] megawatts (MW) of electrical power, and as of and following the Phase II Commencement Date, at least [REDACTED] megawatts (MW) of electrical power, or the holder of title to the property (as shown by reasonable documentary evidence) if title is not held by such customer. Landlord, Fluidstack, and Google acknowledge and agree that any such Fluidstack Strategic Customer will be a third party beneficiary of this Section 4.c.(3) with respect to Google’s obligations under this Section 4.c.(3).

d. Google Assumption Option Without FS Default Trigger. In the event that (i) there is an Event of Default by Fluidstack under the Fluidstack Lease without the occurrence of a FS Default Trigger and (ii) Landlord intends to terminate the Fluidstack Lease on the basis of such Event of Default, Landlord will provide Google with written notice of such Event of Default and such intention at least thirty (30) days prior to Landlord’s planned termination of the Fluidstack Lease the Parties will follow the New Tenant Process. Google and Fluidstack agree that Landlord’s obligation to provide such notice shall not represent evidence of or otherwise result in (by implication or otherwise) any waiver of any of Landlord’s rights against Fluidstack under the Fluidstack Lease with regard to such Event of Default. In the event that the Parties are unable to mutually agree upon a new tenant pursuant to the New Tenant Process, Google will then have the option (but not the obligation), by written notice of the same to Landlord within thirty (30) days after such written notice from Landlord,

-7-

to elect the Google Assumption Option. If Google elects the Google Assumption Option in accordance with this Section 4.d, the parties will follow all requirements in this Agreement related to Google Assumption Option as if Google had elected the Google Assumption Option under Section 4.c of this Agreement.

e. Google Deferral Option. In the event that Google has elected the Deferral Option, then Google agrees to pay to Landlord (i) all Rent under the Fluidstack Lease that is due and owing that Fluidstack has not paid as of the date of such election and (ii) subject to Landlord’s ongoing compliance with its obligations in this clause (e), all additional Rent that becomes due and owing during the Deferral Period that Fluidstack does not pay (all such amounts not paid by Fluidstack under clause (i) and (ii), the “Unpaid FS Amounts”). Landlord may retain and utilize the funds paid by Google in respect of the Unpaid FS Amount to the full extent as if such amounts had been paid to Landlord as Rent under the Fluidstack Lease, and such amounts will be owned by Landlord free and clear of any claims from Google or Fluidstack and shall not be subject to any offset or counterclaim. For the avoidance of doubt, the foregoing sentence is not intended to limit any remedies Google or Fluidstack may have against Landlord under the Fluidstack Lease. Landlord agrees to use commercially reasonable efforts to pursue Fluidstack for the payment in full of any Unpaid FS Amounts, including through litigation, until the Unpaid FS Amounts are paid in full, and Google agrees to cooperate in good faith with Landlord in respect thereof (including assigning any subrogation or similar rights of Google to Landlord in furtherance thereof). Any amounts recovered from Fluidstack in respect of the Unpaid FS Amounts shall be paid to Google in reimbursement of the amounts paid by Google to Landlord. The Deferral Period shall end on the date of the earliest to occur (such date, the “Deferral Option End Date”) of (i) the occurrence of an FS Default Trigger pursuant to clause (i) of such definition, (ii) the date Google fails to pay to Landlord any amounts required by this clause (e) and (iii) the date Google elects by written notice to end the Deferral Period. On the Deferral Option End Date, the Verification Period will cease to toll and will begin to run again in accordance with Section 4.a. from the date of the election of the Deferral Option as if the Deferral Period had not occurred (and, for the avoidance of doubt, at the end of such Verification Period Google will be obligated to elect the Google Assumption Option or, if applicable, the Google Rejection Option). If on or prior to the Deferral Option End Date, Fluidstack has paid in full all Unpaid FS Amounts, and an FS Default Trigger is not otherwise in effect, then the FS Default Trigger that was caused by Unpaid FS Amounts will be deemed to have been cured and this Agreement will continue in full force and effect in accordance with its terms.

5. Notices. Any notice which may or shall be given under the provisions of this Agreement shall be in writing and may be delivered by (i) hand delivery or personal service, (ii) a reputable overnight courier service which provides evidence of delivery, or (iii) e-mail (so long as a confirming copy is forwarded by a reputable overnight courier service within twenty-four (24) hours thereafter), at the physical and email addresses specified below, or at such other addresses as any party may have theretofore specified by written notice delivered in accordance herewith. Such address may be changed from time to time by any party by giving notice as provided herein. Notice shall be deemed given, (a) if delivered by hand or personal service, when delivered, (b) if sent by a reputable overnight courier service, on the Business Day (as defined in the Fluidstack Lease) immediately following the Business Day on which it was sent, or (c) the date the e-mail is transmitted. If notice is delivered by email after 4:30pm (receiver’s time) on a Business Day or at any time on a non-Business Day, the deemed date of the notice will be the Business Day following the date the email is sent.
