Section 7.1(c), no Subsidiary of the Company shall issue or sell Capital Stock in such Subsidiary.

 9. THE AGENTS 

9.1 Appointment and Authorization of the Agents. Each Purchaser hereby irrevocably appoints, designates and authorizes the Note Agent to
act as the “note agent” under the Note Documents and, from and after the execution and delivery of the Collateral Documents pursuant to Section 6.13, the Collateral Agent to act as the “collateral agent” under the Note
Documents and to act as the agent of (and to hold any security interest created by any Note Document for and on behalf of or on trust for) such Purchaser for purposes of acquiring, holding and enforcing any and all Liens on Collateral to be granted
by the Company to secure any of the Obligations, and to take such other action on its behalf in accordance with the provisions of this Agreement and each other Note Document and to exercise such powers and perform such duties, in each case as are
expressly delegated to the Agents by the terms of this Agreement or any other Note Document, together with such powers and discretion as are reasonably incidental thereto. Notwithstanding any provision to the contrary contained elsewhere herein or
in any other Note Document, the Agents shall have no duties or responsibilities, except those expressly set forth herein, nor shall the Agents have or be deemed to have any fiduciary relationship with any Purchaser or participant, and no implied
covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Note Document or otherwise exist against the Agents. Without limiting the generality of the foregoing sentence, the use of the
term “agent” herein and in the other Note Documents with reference to the Agents is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is
used merely as a matter of market custom and is intended to create or reflect only an administrative relationship between independent contracting parties. Without limiting the generality of the foregoing, from and after the execution and delivery of
the Collateral Documents pursuant to Section 6.13, the Purchasers hereby expressly authorize the Collateral Agent to execute any and all documents (including releases) with respect to the Collateral and the rights of the Secured Parties with
respect thereto, as contemplated by and in accordance with the provisions of this Agreement and the Note Documents and acknowledge and agree that any such action by Collateral Agent shall bind the Purchasers. Whether or not expressly stated in any
Note Document, the rights, privileges and immunities of the Agents shall be automatically incorporated by reference therein. Whether or not a party thereto, the Agents shall be express third party beneficiaries of the Notes, including without
limitation the payment waterfall set forth therein. 
 9.2 Liability of Agents. No Agent-Related Person shall (a) be liable for
any action taken or omitted to be taken by any of them under or in connection with this Agreement or any other Note Document or the transactions contemplated hereby, or (b) be responsible in any manner to any Purchaser for any recital,
statement, representation or warranty made by the Company or any officer thereof, contained herein or in any other Note Document, or in any certificate, report, statement or other document referred to or provided for in, or received by the Agents
under or in connection with, this Agreement or any other Note Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Note Document, or the creation, perfection, maintenance of perfection
or priority of any Lien or security interest created or purported to be created under the Note Documents, the convertibility of the Notes and the validity or the sufficiency of the Equity Securities (as defined in the Note), or for any failure of
the Company or any other party (other than Agents) to any Note Document to 

  
 28 












 
perform its obligations hereunder or thereunder, except to the extent such loss resulted from the gross negligence or willful misconduct of such Agent-Related Person, as determined by a final
nonappealable order of a court of competent jurisdiction. The Note Agent shall have no obligation to monitor the Ledger in the absence of being providing such by the Company in accordance with the terms of the Notes, and may, in its sole discretion
either: (i) conclusively rely on the Ledger most-recently delivered to it, (ii) conclusively rely on a statement by a Holder as to the outstanding principal amount of Notes held by it, or (iii) refrain from taking any action until the
Note Agent receives a current Ledger from the Company. No Agent-Related Person shall be under any obligation to any Purchaser or participant to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or
conditions of, this Agreement or any other Note Document, or to inspect the properties, books or records of the Company or any affiliate thereof. 

The Agents shall not have any duties or obligations except those expressly set forth in the Note Documents. Without limiting the generality of
the foregoing, (i) the Agents shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or Event of Default has occurred and is continuing and (ii) the Agents shall not have any duty to take any
discretionary action or exercise any discretionary powers, except, from and after the execution and delivery of the Collateral Documents pursuant to Section 6.13, discretionary rights and powers expressly contemplated hereby that the Collateral
Agent is instructed in writing to exercise by the Required Holders (or such other requisite number or percentage of Holders as provided in Section 10.9).

Agents, in accordance with such Holder’s Pro Rata Share, for any reasonable and documented out-of-pocket expenses not reimbursed by the Company (without limiting

pursuant to Section 6.13, any Lien on any property granted to or held by the Collateral Agent under any Note Document for the benefit of the Secured Parties shall be automatically released (i) upon payment in full of all Obligations (it
being understood and agreed that the conversion in full of a Note by the Holder thereof shall be deemed, for purposes of this Section 9.6, to be a repayment of the entire outstanding principal amount (including all
capitalized interest) of such Note together with any unpaid accrued interest thereon on the date of such conversion), (ii) subject to Section 10.9, if the release of such Lien is approved, authorized or ratified in writing
by the Purchasers or (iii) upon the sale, transfer or other disposition of any Collateral that is not prohibited by the Note Documents. Upon request by the Collateral Agent at any time from and after the execution and delivery of the Collateral
Documents pursuant to Section 6.13, the Purchasers will confirm in writing the Collateral Agent’s authority to release particular types or items of property. In each case as specified in this Section 9.7, the
Collateral Agent will, from and after the execution and delivery of the Collateral Documents pursuant to Section 6.13, promptly (and each Purchaser irrevocably authorizes the Collateral Agent to), at the Company’s expense,

the Note Documents. In connection with any such release, the Collateral Agent shall be entitled to a certificate of a Responsible Officer of the Company stating that such release is authorized and permitted by the Note Documents, upon which the
Collateral Agent may conclusively rely. Each party to this Agreement acknowledges and agrees that the Agents shall not have an obligation to file financing statements, amendments to financing statements, or continuation statements, or to perfect or
maintain the perfection of the Collateral Agent’s Lien on the Collateral.

Agents upon fifteen (15) days’ notice to the Holders. If an Agent resigns under this Agreement, the Holders shall unanimously appoint a successor representative for the Holders. If no successor representative is appointed prior to the
effective date of the resignation of the Agent, the resigning Agent may appoint, after consulting with the Holders and the Company, a successor agent. Upon the acceptance of its appointment as successor representative hereunder, such successor
representative shall succeed to all the rights, powers and duties of the retiring Agent, the term “Agents” shall mean such successor representative and the retiring Agent’s appointment, powers and duties as Agents shall be terminated.
After any retiring Agent’s resignation hereunder as Agent, the provisions of this Section 9 and Section 10 shall inure to its benefit as to any actions taken or omitted to be taken by it while
it was Agent under this Agreement. If no successor representative has accepted appointment as Agent by the date which is fifteen (15) days following a retiring Agent’s notice of resignation, the retiring Agent’s resignation shall
nevertheless thereupon become effective and the Holders shall perform all of the duties of the Agents hereunder until such time, if any, as the Holders appoint a successor representative as provided for above. 

9.9 Intercreditor Agreement. The Collateral Agent is hereby authorized to enter into the Intercreditor Agreement pursuant to
Section 7.1(a) and the parties hereto acknowledge that such Intercreditor Agreement, upon execution of the same, shall be binding upon them. From and after the execution and delivery of the Collateral Documents pursuant to Section 6.13,
each Secured Party hereby (a) agrees that it will be bound by and will take no actions contrary to the provisions of the Intercreditor Agreement, (b) authorizes and instructs the Collateral Agent, without any further consent of such
Secured Party, to enter into the Intercreditor Agreement provided by the Company and accompanied by the certificate specified in Section 7.1(a) and to subject the Liens on the Collateral securing the Obligations to the
provisions thereof and (c) authorizes and instructs the Collateral Agent to execute and deliver on behalf of the Secured Parties any amendment (or amendment and restatement) or modification to the Intercreditor Agreement to provide for the
incurrence of any Indebtedness permitted hereunder or such other amendments as the Required Holders may specify in writing to the Collateral Agent. 
 10.

benefit of and be binding upon the respective successors and assigns of the parties. Nothing in this Agreement, expressed or implied, is intended to confer upon any third party any rights, remedies, obligations, or liabilities under or by reason of

OR RELATING TO THIS AGREEMENT, OR ANY OTHER NOTE DOCUMENT AND EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY
OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM. NOTHING HEREIN SHALL LIMIT THE RIGHT OF ANY PURCHASER, ANY HOLDER OR, FROM AND AFTER

RELATED TO, OR CONNECTED WITH THIS AGREEMENT OR ANY OTHER NOTE DOCUMENT OR THE RELATIONSHIP ESTABLISHED THEREUNDER. 
 10.5
Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and
enforceable replacement for such provision, then (a) such provision shall be excluded from this Agreement, (b) the balance of this Agreement shall be interpreted as if such provision were so excluded, and (c) the balance of this
Agreement shall be enforceable in accordance with its terms. 
 10.6 Counterparts. This Agreement may be executed in one or more
counterparts (and by different parties hereto in different counterparts), each of which shall be deemed an original, but all of which together shall constitute a single contract. Any counterpart of a signature page to this Agreement may be delivered
by facsimile, electronic mail (including “.pdf” or “.tif”) or by means of an electronic signature complying with the U.S. federal ESIGN Act of 2000 or the New York Electronic Signature and Records Act or other transmission method

 10.10 Expenses and Indemnification. 

(a) The Company shall not be responsible for any out-of-pocket
costs or expenses incurred by such Initial Purchasers in connection with the preparation, execution and delivery of this Agreement and the other Note Documents. The Company shall pay all reasonable and documented out-of-pocket costs and expenses of the Agents (including reasonable and documented fees, expenses and disbursements of its outside counsel) relating to the negotiation, preparation and execution of the Note
Documents, review of other documents (including for purposes of due diligence review) in connection with the transactions contemplated hereby and any amendments and waivers hereto or thereto. In addition, the Company agrees to promptly pay in full
after the occurrence of an Event of Default, all costs and expenses (including, without limitation, reasonable and documented fees and disbursements of counsel, agents and professional advisers) incurred by the Holders or the Agents in enforcing any
obligations of or in collecting any payments due hereunder or under the Notes by reason of such Event of Default or in connection with any refinancing or restructuring of the credit arrangements provided under this Agreement in the nature of a
workout, or any insolvency or bankruptcy proceedings. 
 (b) In addition to the payment of expenses pursuant to
Section 10.10(a), the Company (as “Indemnitor”) agrees to indemnify, pay and hold the Purchasers, the Holders and the Agents, and the officers, directors, employees, agents, and affiliates of the
Purchasers, the Holders and the Agents (collectively called the “Indemnitees”) harmless from and against any and all other liabilities, costs, expenses, liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, claims and disbursements of any kind or nature whatsoever (including, without limitation, the reasonable fees and disbursements of counsel for such Indemnitees) in connection with any investigative, administrative or judicial
proceeding commenced or threatened (excluding claims among Indemnitees (other than claims against an Agent acting in its capacity as such) and, with the exception of claims arising out of otherwise indemnifiable matters (e.g., actions to enforce the
indemnification rights provided hereunder), and excluding claims between the Company and an Indemnitee), whether or not such Indemnitee shall be designated a party thereto, which may be imposed on, incurred by, or asserted against that Indemnitee,
in any manner relating to or arising out of this Agreement, the Notes, the Note Documents or the other documents related to the transactions contemplated hereby (including, without limitation, the existence or exercise of any security rights with
respect to the Collateral in accordance with the Security Agreement), the Purchasers’ agreement to purchase the Notes or the use or intended use of the proceeds of any of the proceeds thereof to the Company (the “Indemnified
Liabilities”); provided, that the Indemnitor shall not have any obligation to an Indemnitee hereunder with respect to an Indemnified Liability to the extent that such Indemnified Liability arises from the gross negligence or
willful misconduct of that Indemnitee as determined by a final nonappealable order of a court of competent jurisdiction. Each Indemnitee shall give the Indemnitor prompt written notice of any claim that might give rise to Indemnified Liabilities
setting forth a description of those elements of such claim of which such Indemnitee has knowledge; provided, that any failure to give such notice shall not affect the obligations of the Indemnitor unless (and then solely to the extent) such
Indemnitor is not aware of such claim and is materially prejudiced. The Indemnitor shall have the right at any time during which such claim is pending to select counsel to defend and control the defense thereof and settle any claims for which it is
responsible for indemnification hereunder (provided that the Indemnitor will not settle any such claim without (i) the appropriate Indemnitee’s prior written consent, which consent shall not be unreasonably withheld or (ii) obtaining
an unconditional release of the appropriate Indemnitee from all claims arising out of or in any way relating to the circumstances involving such claim) so long as in any such event the Indemnitor shall have stated in a writing delivered to the
Indemnitee that, as between the Indemnitor and the Indemnitee, the 

  
 34 












 
Indemnitor is responsible to the Indemnitee with respect to such claim to the extent and subject to the limitations set forth herein; provided, that the Indemnitor shall not be entitled to
control the defense of any claim in the event that in the reasonable opinion of counsel for the Indemnitee, there are one or more material defenses available to the Indemnitee which are not available to the Indemnitor, in which case the Indemnitee
may retain separate counsel and the Company will pay the reasonable fees and expenses of such counsel (including the reasonable fees and expenses of counsel to such Indemnitee incurred in evaluating whether such a conflict exists); provided
further, that with respect to any claim as to which the Indemnitee is controlling the defense, the Indemnitor will not be liable to any Indemnitee for any settlement of any claim pursuant to this Section 10.10(b)
that is effected without its prior written consent, which consent shall not be unreasonably withheld. To the extent that the undertaking to indemnify, pay and hold harmless set forth in this Section 10.10(b) may be
unenforceable because it is violative of any law or public policy, the Company shall contribute the maximum portion which it is permitted to pay and satisfy under applicable law, to the payment and satisfaction of all Indemnified Liabilities
incurred by the Indemnitees or any of them. The obligations of each of the parties under this Section 10.10 will survive the payment or transfer of any Note, the enforcement, amendment or waiver of any provision of this
Agreement, the resignation or removal of any Agent and the termination of this Agreement. 
 (c) To the extent permitted by applicable law,
none of the parties hereto shall assert, and each of the parties hereto hereby waives, any claim against the other parties (including their respective affiliates, partners, stockholders, members, directors, officers, agents, employees and
controlling persons), on any theory of liability for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument
contemplated hereby, the transactions contemplated hereunder, any Note Document, the Notes or the use of the proceeds thereof; provided that nothing contained in this Section 10.10(c) shall limit the Notes Parties’ indemnification and
reimbursement obligations to the extent set forth in this Agreement. 
 10.11 Delays or Omissions. It is agreed that no delay or
omission to exercise any right, power or remedy accruing to each Purchaser, upon any breach or default of the Company under this Agreement or any other Note Document shall impair any such right, power or remedy, nor shall it be construed to be a
waiver of any such breach or default, or any acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or
thereafter occurring. It is further agreed that any waiver, permit, consent or approval of any kind or character by a Purchaser of any breach or default under this Agreement, or any waiver by such Purchaser of any provisions or conditions of this
Agreement must be in writing and shall be effective only to the extent specifically set forth in writing and that all remedies, either under this Agreement, or by law or otherwise afforded to such Purchaser, shall be cumulative and not alternative.

 10.12 Waiver of Conflicts. Each party to this Note acknowledges that Cooley LLP (“Cooley”), outside general
counsel to the Company, has in the past performed and is or may now or in the future represent the Holders or the Holders’ affiliates in matters unrelated to the transactions contemplated by this Note (the “Note
Financing”), including representation of the Holders or the Holders’ affiliates in matters of a similar nature to the Note Financing. The applicable rules of professional conduct require that Cooley inform the parties hereunder of
this representation and obtain their consent. Cooley has served as outside general counsel to the Company and has negotiated the terms of the Note Financing solely on behalf of the Company. The Company and the Holders hereby (i) acknowledge
that they have had an opportunity to ask for and have obtained information relevant to such representation, including disclosure of the reasonably foreseeable adverse consequences of such representation; (ii) acknowledge that with respect to
the Note Financing, Cooley has represented solely the Company, and not any Holder or any stockholder, board member or employee of the Company or director, stockholder or employee of the Holder; and (iii) gives the Holder’s informed consent
to Cooley’s representation of the Company in the Note Financing. 

  
 35 












 10.13 Obligations Several. The Purchasers’ obligations hereunder are several and
not joint obligations and no Purchaser shall have any liability to any Person for the performance or non-performance of any obligation by any other Purchaser hereunder. 

10.14 Survival of Representations and Warranties. All of the representations and warranties made by the Note Parties and their
Subsidiaries herein shall survive the execution and delivery of this Agreement, any investigation by or on behalf of any Purchaser, acceptance of the Notes and payment therefor, or termination of this Agreement. 

10.15 Entire Agreement. This Agreement and the other Note Documents constitute the entire contract among the parties hereto regarding to
the subject matters addressed herein and supersede any and all previous agreements, negotiations, and discussions, oral or written, by the parties regarding the subject matters addressed herein. 

10.16 Withholding. The Company shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this
Agreement such amounts as it is required to deduct and withhold under the Code, or any Tax law, with respect to the making of such payment. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the Person in respect of whom such deduction and withholding was made. If a payment is payable (in whole or in part) in consideration other than cash and if the cash portion of any such payment is insufficient to
satisfy all required Tax withholding obligations, the Company shall retain an amount of the non-cash consideration otherwise payable equal in value to the amount required to satisfy any applicable withholding
taxes (as reasonably determined by the Company).10.17 PATRIOT ACT. The Agents hereby notify the Company that pursuant to the requirements of the PATRIOT Act, the Company may be required to obtain, verify and record information that identifies
the Company, its subsidiaries and the Guarantors, including their respective names, addresses and other information that will allow the Agent to identify, the Company, its subsidiaries and the Guarantors in accordance with the PATRIOT Act.

		 		 	Date of Note:	  	[__], 2021
				
		 		 	Initial Principal Amount of Note:	  	$[__], plus any PIK Interest that has accrued and been capitalized pursuant to the terms of this Note

 For value received CORE SCIENTIFIC HOLDING
CO., a Delaware corporation (the “Company”), promises to pay to the undersigned holder or such party’s successors or permitted assigns (the “Holder”) the principal amount set
forth above with interest to accrue on such outstanding principal amount at a rate of 10% per annum, 4% of which shall be payable in cash (“Cash Interest”) and 6% of which shall be payable in kind by
capitalizing such interest payment and increasing the outstanding principal amount of this Note by the amount thereof (“PIK Interest”). Interest shall accrue on the outstanding principal amount of this Note commencing on (and
including) the date of original issuance thereof (or the most recent interest payment date) and continuing until the earlier to occur of (x) the date this Note is repaid or prepaid in full and (y) the date this Note is converted in full by
the Holder pursuant to Section 2 hereof. Cash Interest shall be due and payable and PIK Interest shall be capitalized quarterly in arrears on the first day of each fiscal quarter, commencing on October 1, 2021.
Interest shall be computed on the basis of a year of 365 days for the actual number of days elapsed. This Note shall be automatically deemed to include any accrued PIK Interest thereon and the Company shall not be obligated to issue any subsequent
Notes reflecting PIK Interest. This Note is one of the “Notes” issued pursuant to the Purchase Agreement. All capitalized terms used but not otherwise defined in this Note will have the same meanings in this Note as in the Purchase
Agreement referred to below. 











 The following is a statement of the rights of the Holder and the conditions to which this
Note is subject, and to which the Holder, by the acceptance of this Note, agrees: 
  

	1.	 BASIC TERMS. 



(a) Series of Notes. This convertible promissory note (this “Note”) is issued as part of a series of
notes designated by the Note Series above (collectively, the “Notes”), having an initial aggregate principal amount of up to $300,000,000.00 and issued pursuant to, and to those persons and entities (collectively, the
“Holders”) party, as Purchasers, to, that certain Convertible Note Purchase Agreement, dated as of even date herewith (as amended, restated, supplemented and/or otherwise modified from time to time, the “Purchase
Agreement”), by and among the Company, each Purchaser party thereto, U.S. Bank National Association, as Note Agent, and, upon the execution and delivery of the Collateral Documents pursuant to Section 6.13 of the Purchase
Agreement, U.S. Bank National Association, as Collateral Agent for the Secured Parties. The Company shall maintain a ledger of all Holders (“Ledger”), which shall include all PIK Interest accrued and capitalized, and which
shall be available (i) promptly upon request to the Agents and the Holder, (ii) promptly after any transfer or assignment of any Note, (iii) promptly upon conversion of any Note and (iv) on the tenth business day prior to any
interest payment date. 
 (b) Payments. 

(i) Voluntary Prepayments. Subject to and following the expiration of any applicable lockup period set forth under any lockup agreement
to which the Holder, the Company and the Company’s underwriters are a party, and unless otherwise converted in full or in part pursuant to Section 2 hereof (including following delivery of the Company’s notice
referred to in this subsection (b)(i)(2)), the Company may at any time, upon ten (10) Business Days’ prior written notice to the Holder and the Note Agent (which notice may be conditioned or rescinded upon such events as may be specified
in such notice) prepay all or any portion of this Note in an amount equal to (x) the outstanding principal amount (including all accrued PIK Interest not already added to the principal amount of this Note) of this Note being prepaid at such
time, together with all accrued unpaid Cash Interest on such outstanding principal amount at such time multiplied by (y) 200% (such amount, the “Repayment Amount”). 

(ii) Repayment. Unless otherwise prepaid by the Company pursuant to Section 1(b)(i) or converted in full
pursuant to Section 2 hereof, this Note shall be repaid in full on the earlier to occur of (x) April 19, 2025 (the “Maturity Date”) and (y) acceleration by the Holders representing at
least twenty-five percent (25%) of the aggregate outstanding principal amount of the Notes issued pursuant to the Purchase Agreement at such time after the occurrence of an Event of Default in accordance with the terms hereof, in each case, in an
amount equal to the outstanding principal (including all accrued PIK Interest not already added to the principal amount of this Note) of this Note, plus all unpaid accrued Cash Interest thereon. 

(iii) Payments Generally. 

(1) This Note and the other Notes issued pursuant to the Purchase Agreement are pari passu in right of payment and all payments (other
than conversion) under this Note and such other Notes shall be made in accordance with each Holder’s Pro Rata Share. All payments shall be applied first, to the payment of expenses due under this Note and the other Note Documents to the
Agents, second, to the payment of expenses due under this Note and the other Note Documents to the Holders, third, unpaid accrued interest of this Note and fourth, if the amount of payment exceeds the amount of all such expenses
and accrued interest, to the payment of outstanding principal (including all accrued PIK Interest not already added to the principal amount of this Note) of this Note. The conversion of this Note by the Holder pursuant to the terms hereof shall be
deemed to be a repayment of the full outstanding principal amount (including all accrued PIK Interest not already added to the principal amount of this Note) of such Note together with any unpaid accrued Cash Interest thereon on the date of such
conversion. 

  
 2 












 (2) All payments to be made by the Company shall be made without condition or deduction for
any counterclaim, defense, recoupment or setoff, except with respect to Taxes required to be deducted and/or withheld under applicable law. All payments (other than by means of conversion pursuant to the terms of the Notes), including any
prepayments, of interest and principal to be made by the Company hereunder shall be made by the Company to the Note Agent, in cash, for the account of the respective Holders to which such payment is owed, at the applicable Notes Agent’s
Principal Office for payment and in same day funds not later than 11:00 a.m. on the date specified herein. The Notes Agent will promptly distribute to each Holder its Pro Rata Share (or other applicable share as provided herein) of such payment in
like funds as received by wire transfer to each Holder at the address specified in the Holder’s Administrative Questionnaire (or at such other address as the Holder may indicate in writing to the Note Agent from time to time). All payments
received by the Notes Agent after 11:00 a.m. may (at the sole discretion of the Notes Agent) in each case be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue. 

(3) If any payment to be made by the Company shall come due on a day other than a Business Day, any interest shall be payable, and any PIK
Interest shall be capitalized, on the next succeeding Business Day without additional interest accruing thereon. 
 (4) Whenever any payment
received by the Notes Agent under this Agreement or any of the other Notes Documents is insufficient to pay in full all amounts due and payable to the Notes Agent and the Holders under or in respect of this Agreement and the other Notes Documents on
any date, such payment shall be distributed by the Notes Agent and applied by the Notes Agent and the Holders in the order of priority set forth in Section 1(b)(iii)(1). If the Notes Agent receives funds for application to
the Obligations of the Company under or in respect of the Notes Documents under circumstances for which the Notes Documents do not specify the manner in which such funds are to be applied, the Notes Agent may, but shall not be obligated to, elect to
distribute such funds to the Holders in accordance with the Holder’s Pro Rata Share of such of the outstanding Notes or other Obligations then owing to the Holder. 

(iv) Withholding. Notwithstanding anything to the contrary herein, the Company shall be entitled to deduct and withhold from the
consideration otherwise payable under the Note such amounts as it is required to deduct and withhold under the Code, or any other tax law, with respect to the making of such payment. To the extent that amounts are so withheld, such withheld amounts
shall be treated for all purposes of this Note as having been paid to the Person in respect of whom such deduction and withholding was made. If a payment is payable (in whole or in part) in consideration other than cash and if the cash portion of
any such payment is insufficient to satisfy all required tax withholding obligations, the Company shall retain an amount of the non-cash consideration otherwise payable equal in value to the amount required to
satisfy any applicable withholding taxes (as reasonably determined by the Company). 
  

	2.	 CONVERSION. 



(a) Conversion upon an Offering. In the event that the Company (i) issues and sells shares of its equity securities
(“Equity Securities”) to investors (the “Investors”) in a private offering or placement with total gross proceeds to the Company of at least $50,000,000 (excluding the conversion of the Notes or other
convertible securities issued for capital raising purposes (e.g., Simple Agreements for 

  
 3 












 
Future Equity)), (ii) issues and sells its common stock (“Common Stock”) to Investors in an underwritten public offering pursuant to an effective registration statement
filed with the Securities and Exchange Commission in accordance with the Act or under equivalent securities laws and regulations of any other jurisdiction (including, for the avoidance of doubt, a SPAC), (iii) lists its Common Stock (other than
shares of Common Stock not eligible for resale under Rule 144 under the Securities Act) on a national securities exchange by means of an effective registration statement on Form S-1 filed by the Company with
the SEC that registers shares of existing capital stock of the Company for resale, as approved by the Company’s board of directors, or (iv) lists its Common Stock on any stock exchange (the occurrence of each event set forth in clauses
(i) through (iv) above, an “Offering” and, together with the occurrence of a Change of Control as provided in Section 2(b) below, each, a “Conversion Event”), in each case, while this Note
remains outstanding, the Holder shall have the right at any time and from time to time during the period commencing on the date of consummation of such Offering until the Maturity Date, to convert, in whole or in part, the outstanding principal
amount (including all accrued PIK Interest not already added to the principal amount of this Note) of this Note, together with all unpaid accrued Cash Interest thereon, into Equity Securities or Common Stock of the Company (as applicable) at a
conversion price equal to the Applicable Conversion Price (as defined below) (which shall be determined, for the avoidance of doubt, on the date of the consummation of such Offering). The issuance of Equity Securities or Common Stock by the
Company (as applicable) pursuant to the conversion of this Note shall be upon and subject to the same terms and conditions (other than as otherwise set forth herein) applicable to Equity Securities or Common Stock of the Company (as applicable),
sold in the applicable Offering. 
 (b) Conversion upon a Change of Control. In the event the Company consummates a Change of
Control (as defined below) while this Note remains outstanding, the Company shall repay the outstanding principal amount of this Note in an amount equal to the Repayment Amount; provided, however, that upon the written election
of the Holder made not less than five (5) days prior to the Change of Control, the Company shall convert the outstanding principal amount of this Note (including all accrued PIK Interest not already added to the principal amount of this Note)
and any unpaid accrued Cash Interest into Common Stock at a conversion price equal to the Applicable Conversion Price (which shall be determined, for the avoidance of doubt, on the date of consummation of such Change of Control) (assuming conversion
of all securities convertible into Common Stock and exercise of all outstanding options and warrants, but excluding the shares of equity securities of the Company issuable upon the conversion of Notes or other convertible securities issued for
capital raising purposes (e.g., Simple Agreements for Future Equity)). The Company shall give the Holder and the Note Agent written notice of any Change of Control at least ten (10) Business Days prior to the consummation thereof, which notice
will contain the material terms and conditions (including price and form of consideration) of the Change of Control, the identity of the parties to the Change of Control and the intended date of the Change of Control. 

For purposes of this Note, (i) a “Change of Control” means, at any time, any Person or “group” other
than the Permitted Holders (within the meaning of Rules 13d-3 and 13d-5 under the Exchange Act) shall have obtained the power (whether or not exercised) to elect a
majority of the members of the board of directors of the Company; (ii) “Permitted Holders” means each of BCV 55 LLC, BCV 66 LLC, BCV 77 LLC and each of their respective affiliates; (iii) “Fair Market Value Per
Common Share” means the cash and/or the value of the property, rights or securities to be paid or distributed per share of Common Stock of the Company to the holders of Common Stock of the Company pursuant to a Change of Control or a
SPAC (with the value of such property, rights or securities being determined in good faith by the board of directors of the Company); (iv) the “Applicable Conversion Price” means a conversion price equal to (a) 80% of either
(x) the cash price paid per share for Equity Securities or Common Stock of the Company (as applicable) by the Investors in an Offering (other than a SPAC) or (y) the Fair Market Value Per Common Share in a Change of Control or a SPAC, as
applicable, if the Conversion Event occurs on or prior to April 19, 2022, (b) 75% of either (x) the cash price paid per share for Equity Securities or 

  
 4 












 
Common Stock of the Company (as applicable) by the Investors in an Offering (other than a SPAC) or (y) the Fair Market Value Per Common Share in a Change of Control or a SPAC, as applicable,
if the Conversion Event occurs on or after April 19, 2022 but prior to April 19, 2023, (c) 70% of either (x) the cash price paid per share for Equity Securities or Common Stock of the Company (as applicable) by the Investors in an
Offering (other than a SPAC) or (y) the Fair Market Value Per Common Share in a Change of Control or a SPAC, as applicable, if the Conversion Event occurs on or after April 19, 2023 but prior to April 19, 2024 and (d) 65% of either
(x) the cash price paid per share for Equity Securities or Common Stock of the Company (as applicable) by the Investors in an Offering (other than a SPAC) or (y) the Fair Market Value Per Common Share in a Change of Control or a SPAC, as
applicable, if the Conversion Event occurs on or after April 19, 2024 but prior to April 19, 2025; (v) in connection with any SPAC, each reference to “Company” shall be deemed to also refer to a Parent Entity that has become a co-obligor with respect to the Company’s Obligations hereunder (except that solely such Parent Entity, and not Core Scientific Holding Co. (or its successor by merger), shall be obligated to deliver Equity
Securities or Common Stock pursuant to this Section 2); and (vi) in connection with any SPAC, each reference to “Common Stock” shall be deemed to refer to the kind and the amount of property that a holder of
one share of Common Stock of the Company would be entitled to receive on account of the consummation of such SPAC. 
 (c) Procedure for
Conversion. Upon the conversion in whole or in part of this Note into Equity Securities or Common Stock of the Company (as applicable), the Holder shall surrender this Note to the Company and deliver to the Company any documentation reasonably
required by the Company (including, in the case of an Offering, all financing documents executed by the Investors in connection with such Offering). The Company shall not be required to issue or deliver the Equity Securities or Common Stock of the
Company (as applicable) into which this Note may convert until the Holder has surrendered this Note to the Company and delivered to the Company any such documentation. The Company shall, as soon as practicable after the surrender of this Note and
delivery to the Company of such documentation deliver to the Holder (i) a certificate or certificates for the number of shares of Equity Securities or Common Stock of the Company (as applicable) into which this Note is convertible in whole or
in part, rounded downward to the nearest whole share and cash for the amounts not so converted as a result of the above-referenced downward rounding, registered in the name of such Investor or registered nominee or assignee and (ii) to the
extent the Holder has converted only a portion of the outstanding principal amount of this Note, a replacement Note for the outstanding principal amount of this Note not converted. Upon the conversion in full or in part of this Note into Equity
Securities or Common Stock of the Company (as applicable) pursuant to the terms hereof, in lieu of any fractional shares to which the Holder would otherwise be entitled, the Company shall pay the Holder cash equal to such fraction multiplied by the
price at which this Note converts. Upon conversion of this Note in full or in part and payment of cash representing any fractional share pursuant to this Section 2(c), the Company shall be forever released from all its
obligations and liabilities under this Note and this Note shall be deemed of no further force or effect, whether or not the original of this Note has been delivered to the Company for cancellation. 

(d) Taxes. The Company shall pay any and all stamp, stock transfer, stock issuance and other similar taxes that may be payable in
respect of any issuance or delivery of shares of Equity Securities or Common Stock of the Company (as applicable) upon conversion of this Note pursuant to this Section 2. The Company shall not, however, be required to pay
any income, capital gains or similar tax of the recipient of Equity Securities or Common Stock of the Company (as applicable) or any tax which may be payable in respect of any transfer involved in the issuance and delivery of shares of Equity
Securities or Common Stock of the Company (as applicable) in a name other than that in which this Note so converted was registered, and no such issuance or delivery shall be made unless and until the person or entity requesting such issuance has
paid to the Company the amount of any such tax or has established, to the satisfaction of the Company, that such tax has been paid.

an Event of Default under subsection (v) or (vi) below), this Note shall accelerate and all principal (including all accrued PIK Interest not already added to the principal amount of this Note) and all unpaid accrued Cash Interest shall

Agreement and such non-observance or non-performance shall not have been remedied or waived within thirty (30) days after the earlier of (i) the Company
becoming aware of such non-observance or non-compliance or (ii) receipt by the Company of notice from a Holder of such
non-observance or non-compliance; 
 (iv) the Company and
its Subsidiaries fail to observe or perform any other term, covenant or provision contained in the Purchase Agreement (other than those specified elsewhere in this Section 4) or any other Note Document and such non-observance or non-performance shall not have been remedied or waived within thirty (30) days after the earlier of (i) the Company becoming aware of such non-observance or non-compliance or (ii) receipt by the Company of notice from a Holder of such non-observance or non-compliance;

each case, beyond the grace period, if any, if the effect of such non-payment, breach or default is to cause such Indebtedness to become or be declared due and payable (or subject to a compulsory repurchase or
redemption) prior to its stated maturity; 
 (viii) any court, government, or Governmental Authority shall condemn, seize or otherwise
appropriate, or take custody or control of, all or any material portion of the property of the Company and its Subsidiaries, taken as a whole;

(xi) the institution by the Company, any ERISA Affiliate or any Subsidiary of steps to terminate any Plan if, in order to effectuate such
termination, the Company, such ERISA Affiliate or such Subsidiary, as the case may be, would be required to make a contribution to such Plan, or would incur a liability or obligation to such Plan, in excess of $10,000,000, or the institution by the

	5.	 MISCELLANEOUS PROVISIONS. 



(a) Waivers. The Company hereby waives demand, notice, presentment, protest and notice of dishonor. 

(b) Further Assurances. The Holder agrees and covenants that at any time and from time to time the Holder will promptly execute and
deliver to the Company such further instruments and documents and take such further action as the Company may reasonably require in order to carry out the full intent and purpose of this Note and to comply with state or federal securities laws or
other regulatory approvals. 
 (c) Transfers of Notes. Subject to the Company’s prior written consent (not to be unreasonably
withheld or delayed) and to the extent permitted by applicable law, this Note may be transferred only upon its surrender to the Company for registration of transfer, duly endorsed, or accompanied by a duly executed written instrument of transfer in
form satisfactory to the Company. Thereupon, this Note shall be reissued to, and registered in the name of, the transferee, or a new Note for like principal amount and interest shall be issued to, and registered in the name of, the transferee.
Interest and principal shall be paid solely to the registered holder of this Note. Such payment shall constitute full discharge of the Company’s obligation to pay such interest and principal. Upon the effectiveness of any transfer pursuant to

do any of the foregoing, for up to 180 days following the consummation of any such offering. For purposes of this paragraph, “Company” includes the Company or any other
direct or indirect parent entity of the Company into which the Company merges or consolidates. The Company may place restrictive legends on the certificates representing the shares subject to this paragraph and may impose stop transfer instructions
with respect to the Securities and such other shares of stock of each Holder and any transferee thereof (and the shares or securities of every other person subject to the foregoing restriction) until the end of such period. Each Holder and any
transferee thereof shall enter into any agreement reasonably required by the underwriters for such an offering to implement the foregoing within any reasonable timeframe so requested. The underwriters for any such offering are intended third party
beneficiaries of this paragraph and shall have the right, power and authority to enforce the provisions of this paragraph as though they were parties hereto. The provisions of this paragraph shall survive any conversion and/or repayment of this
Note. 
 (e) Waiver of Statutory Information Rights. Prior to the conversion in full of this Note, the Holder, on behalf of the Holder
and all beneficial owners of the Securities now or hereafter owned by the Holder (a “Beneficial Owner”), acknowledges and agrees that that neither the Holder nor any of the Beneficial Owners will have any right to receive any
information from the Company by virtue of ownership of any of the Securities. Without limiting the foregoing, prior to the conversion in full of this Note, to the fullest extent permitted by law, the Holder hereby unconditionally and irrevocably
waives all rights under Section 220 of the Delaware General Corporation Law and all such similar information and/or inspection rights that may be provided under the law of any jurisdiction, or any federal, state or foreign regulation, that are,
or may become, applicable to the Company or the Company’s capital stock (the “Inspection Rights”) on behalf of the Holder and all Beneficial Owners. The Holder, on behalf of the Holder and all Beneficial Owners, hereby
covenants and agrees that neither the Holder nor any Beneficial Owner shall directly or indirectly commence, voluntarily aid in any way, prosecute, assign, transfer, or cause to be commenced any claim, action, cause of action, or other proceeding to
pursue or exercise the Inspection Rights. The Holder hereby further warrants and represents that the Holder has reviewed this waiver with its legal counsel, and that the Holder knowingly and voluntarily waives its rights otherwise provided by
Section 220 of the Delaware General Corporation Law (or under similar rights under other applicable law). Notwithstanding the foregoing, Beneficial Owners that were issued Equity Securities other than by way of a conversion in connection with
an Offering will not be subject to this Section 5(e). The terms of this Section 5(e) shall survive any repayment of this Note. 

(f) Amendment and Waiver. This Note and any term hereof may only be amended, waived or modified in accordance with Section 10.9 of
the Purchase Agreement. Upon the effectuation of such amendment, waiver or modification with the consent of the Required Holders or each Holder, as applicable, in conformance with Section 10.9 of the Purchase Agreement, such amendment,
waiver or modification shall be effective as to, and binding against the Holders of, all of the Notes, and the Company shall promptly give written notice thereof to the Holder if the Holder has not previously consented to such amendment, waiver or
modification in writing; provided that the failure to give such notice shall not affect the validity of such amendment, waiver or modification. 

(g) Binding Agreement. The terms and conditions of this Note shall inure to the benefit of and be binding upon the respective successors
and assigns of the parties. Nothing in this Note, expressed or implied, is intended to confer upon any third party any rights, remedies, obligations, or liabilities under or by reason of this Note, except as expressly provided in this Note.
Notwithstanding any assumption of the Company’s Obligations under this Note by a Parent Entity in accordance with Section 10.1 of the Purchase Agreement, Core Scientific Holding Co. (or its successor by merger) shall remain a co-obligor with such Parent Entity with respect to such Obligations (other than any such Obligation of the Company to deliver Equity Securities or Common Stock pursuant to Section 2 of this
Note, with respect to which delivery Obligation Core Scientific Holding Co. (or its successor by merger) shall be a Guarantor).

mail (including “.pdf” or “.tif”) or by means of an electronic signature complying with the Electronic Signatures in Global and National Commerce Act, the New York Electronic Signature and Records Act or any other similar state

(i) Headings; Interpretation. Paragraph headings used in this Note are included for convenience of reference only and will not modify

(j) Notices. All communications and notices required or permitted to be given hereunder shall be delivered in accordance with
Section 10.8 of the Purchase Agreement. 
 (k) GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES
HEREUNDER SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES (OTHER THAN SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW) THEREOF. 
 (l) Expenses, Etc. This Note is subject
to the provisions of Section 10.3 (Jurisdiction and Venue), Section 10.4 (Waiver of Jury Trial) and Section 10.10 (Expenses and Indemnification) of the Purchase Agreement, which are by this reference incorporated herein in full,
mutatis mutandis. 
 (m) Delays or Omissions. It is agreed that no delay or omission to exercise any right, power or remedy
accruing to each Holder, upon any breach or default of the Company under this Note or any Note shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach or default, or any acquiescence therein, or of
or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. It is further agreed that any waiver, permit,
consent or approval of any kind or character by a Holder of any breach or default under this Note, or any waiver by such Holder of any provisions or conditions of this Note must be in writing and shall be effective only to the extent specifically
set forth in writing and that all remedies, either under this Note, or by law or otherwise afforded to such Holder, shall be cumulative and not alternative. 

(n) Entire Agreement. This Note and the other Note Documents constitute the entire contract among the parties hereto regarding to the
subject matters addressed herein and supersede any and all previous agreements, negotiations, and discussions, oral or written, by the parties regarding the subject matters addressed herein.

Company and its officers and board members, in making its investment or decision to invest in the Company.

 (p) Broker’s Fees. Each party hereto represents and warrants that
no agent, broker, investment banker, person or firm acting on behalf of or under the authority of such party hereto is or will be entitled to any broker’s or finder’s fee or any other commission directly or indirectly in connection with
the transactions contemplated herein. Each party hereto further agrees to indemnify each other party for any claims, losses or expenses incurred by such other party as a result of the representation in this subsection being untrue. 

(q) Repayment Amounts. The parties hereto hereby acknowledge and agree that payment of any Repayment Amount hereunder constitutes
liquidated damages and not a penalty, the actual amount of damages to the Holder or profits lost by the Holder as a result of a prepayment or conversion of this Note would be impracticable and extremely difficult to ascertain and the Repayment
Amount hereunder is part of an arm’s length transaction between sophisticated parties represented by counsel and is bargained for consideration provided for and agreed to by mutual agreement of the Company and the Holder. THE NOTE PARTIES
EXPRESSLY WAIVE THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE REPAYMENT AMOUNT TO THE EXTENT SUCH REPAYMENT AMOUNT IS DUE AND PAYABLE IN ACCORDANCE WITH THIS NOTE. The Note Parties
expressly agree that: (i) the Repayment Amount shall be payable notwithstanding the then prevailing market rates at the time payment is made; (ii) the Note Parties shall be estopped hereafter from claiming differently than as agreed to in
this paragraph; and (iii) their agreement to pay the Repayment Amount is a material inducement to the Holder to purchase the Note. 

(r) Tax Forms. Prior to the date hereof, the Holder (and, in the event any Person becomes an assignee or participant in respect of this
Note, prior to the date such Person becomes such an assignee or participant) shall have delivered to the Company executed copies of Internal Revenue Service (“IRS”) Form W-9 or
appropriate IRS Form W-8, as applicable, as well as any reasonably necessary supporting information, certifying that any payments to such Holder (or assignee or participant) under this Note are exempt from
U.S. federal withholding tax. The Holder (and assignee or participant) further agrees that if any such form or certification expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the
Company in writing of its legal inability to do so. 
 (s) Calculations. The Company shall be responsible for making all calculations
with respect to this Note, including, without limitation, accrued interest (including PIK Interest), the Fair Market Value Per Common Share and the Applicable Conversion Price and shall forward such calculations to the Agents and the Holder upon
request.
