 Exhibit 10.1 

TRANSITIONAL SERVICES AND SEPARATION AGREEMENT 

This Transitional Services and Separation Agreement (“Agreement”) is made between Aerpio Pharmaceuticals, Inc., a Delaware
corporation (the “Company”), and Kevin G. Peters, MD (“Executive”). The Company together with Executive shall be referred to as the “Parties”. 

WHEREAS, the Parties entered into an executive employment agreement dated November 1, 2012 (the “Prior
Agreement”), which was superseded by the Employment Agreement dated March 15, 2017 (the “Employment Agreement”); 

WHEREAS, pursuant to the Employment Agreement, the Company and Executive each retained the right to terminate Executive’s
employment by the Company without any breach of the Employment Agreement under the circumstances set forth in Section 3 of the Employment Agreement; 

WHEREAS, the Company desires to continue Executive’s at-will employment through the
earlier of (i) March 31, 2021 or (ii) the last day of the MTEC trial (in either case, the “Anticipated Date of Termination”); 

WHEREAS, if Executive enters into and complies with this Agreement, Executive’s employment with the Company will end pursuant to
Section 3(d) of the Employment Agreement on the Anticipated Date of Termination, unless his employment ends on an earlier date consistent with the terms of this Agreement (such actual last day of employment, the “Date of
Termination”), and Executive will be eligible to receive the severance pay and benefits as described in this Agreement; 

WHEREAS, this Agreement is the “Separation Agreement and Release” referred to in the Employment Agreement; 

WHEREAS, the Parties agree that this Agreement was enclosed with a “Notice of Termination”, and that such notice
accurately reflects the Accrued Benefit as defined in the Employment Agreement and satisfies the Company’s obligations related to a Notice of Termination under Section 3(f) of the Employment Agreement; and 

WHEREAS, the payments and benefits set forth in this Agreement are the exclusive payments and benefits to Executive in connection with
the ending of Executive’s employment. By entering into this Agreement, Executive acknowledges and agrees that he is not entitled to any other severance pay, benefits or equity rights including without limitation pursuant to any severance plan,
or program or arrangement. 
 NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the Parties hereby agree as follows: 
 1. Conditions. To receive the benefits set forth in this Agreement, Executive must
(i) enter into and comply with this Agreement, (ii) not either (A) be terminated by the Company for Cause (as defined in the Employment Agreement), or (B) resign prior to the Anticipated Date of Termination; (iii) provide
services and work cooperatively to the reasonable satisfaction of the Company’s President (“President”) during the Transition Period; and (iv) if requested by the Company, enter into a certificate provided by the
Company updating the release of claims set forth in Section 9 of this Agreement (the “Certificate”) on or after the Date of Termination within the time period set forth therein (collectively, the “Conditions”).

 2. Transition Period. 

(a) Duties during the Transition Period. If Executive satisfies the Conditions, Executive’s at-will employment will continue,
along with the compensation and benefits specified below, until the Anticipated Date of Termination. The time period between the date of this Agreement and the Date of Termination is referred to herein as the “Transition Period.”
During the Transition Period, Executive will continue to work and provide services to the Company on a full-time basis, unless otherwise requested by the President. It is anticipated that Executive will continue to perform his regular duties, as
well as any other duties that may be requested by the President, including relating to transitioning Executive’s work. Executive agrees to work cooperatively with the leadership team during the Transition Period. 

(b) Compensation, Benefits and Vesting during the Transition Period. Provided that Executive satisfies each of the Conditions, during
the Transition Period: (i) Executive will be paid his regular Base Salary (as defined in the Employment Agreement); (ii) he will remain eligible to participate in the Company’s group employee benefit plans and (iii) his outstanding equity
awards will continue to vest through the Date of Termination consistent with the Equity Documents (as defined below). 
 (c) For the
avoidance of doubt, if the Company terminates Executive’s employment for Cause or Executive resigns prior to the Anticipated Date of Termination, or if Executive fails to satisfy any of the Conditions, then his employment will end, he will
cease vesting as of the Date of Termination, he shall be entitled to the Accrued Benefit (as set forth in Section 4), and he shall have no further rights to any compensation or benefits from the Company or any of its affiliates. 

3. Resignation from Positions. Executive hereby resigns as of the Date of Termination as an officer of the Company as well as from any other
director or officer positions he holds with any of the Company’s subsidiaries or entities affiliated with the Company. Executive agrees to execute any documentation that may be reasonably requested by the Company to effectuate such
resignations. 
 4. Accrued Benefit. Executive acknowledges and agrees that in connection with the ending of his employment, he will be paid
in full for: (i) any Base Salary (as defined in the Employment Agreement) earned through the Date of Termination, (ii) expense reimbursements (subject to, and in accordance with, Section 2(c) of the Employment Agreement), and (iii) any unused
vacation that accrued through the Date of Termination. In addition, the Company shall provide Executive any vested benefits Executive may have under any employee benefit plan of the Company through the Date of Termination, which vested benefits
shall be paid and/or provided in accordance with the terms of such employee benefit plans. For the avoidance of doubt, Executive acknowledges that he has already received his 2020 bonus and is not owed any further incentive compensation. 

  
 2 

 5. Severance Benefits. In exchange for Executive entering into and complying with this
Agreement, including satisfying the Conditions, then following the Date of Termination: 
 (a) the Company shall pay Executive an amount
equal to twelve (12) months’ Base Salary (the “Severance Amount”); and 
 (b) if Executive was participating in the
Company’s group health plan immediately prior to the Date of Termination and elects COBRA health continuation, then the Company shall pay to Executive a monthly cash payment for twelve (12) months or Executive’s COBRA health
continuation period, whichever ends earlier, in an amount equal to the monthly employer contribution that the Company would have made to provide health insurance to Executive if Executive had remained employed by the Company; and 

(c) the unvested portion of the time-based stock options and other stock-based awards held by Executive in which Executive would have vested
if he had remained employed for an additional twelve (12) months following the Date of Termination (the “Acceleration Awards”) shall become vested on the Date of Termination. If Executive does not enter into this Agreement or does
not satisfy the Conditions, the Acceleration Awards shall lapse and be forfeited on the Date of Termination. 
 The amounts payable under Section 5(a) and
(b) of this Agreement shall be paid out in substantially equal installments in accordance with the Company’s payroll practice over twelve (12) months, commencing on the first practicable payroll date after the Date of Termination. Each payment
pursuant to this Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2). 
 6. Change in
Control. Notwithstanding the foregoing, in the event that a Change in Control (as defined in the Employment Agreement) occurs prior to the Date of Termination or within three (3) months following the Date of Termination and Executive
satisfies the Conditions, (i) the Severance Amount in Section 5(a) shall equal the sum of (A) 18 months of Executive’s Base Salary (or Executive’s Base Salary in effect immediately prior to the Change in Control, if higher) plus (B) 1.5
times Executive’s Target Annual Incentive Compensation (as defined in the Employment Agreement) and shall be paid out in a lump sum within 60 days after the Date of Termination; (ii) the COBRA health continuation payments by the Company in
Section 5(b) shall continue for eighteen (18) months or Executive’s COBRA health continuation period, whichever ends earlier, and (iii) in lieu of the partial accelerated vesting described in Section 5(c), and except as otherwise expressly
provided in any applicable option agreement or other stock-based award agreement, all stock options and other stock-based awards held by Executive subject to time-based vesting (the “Time-Based Equity Awards”) shall immediately accelerate
and become fully exercisable or nonforfeitable as of the Date of Termination. For the avoidance of doubt, (i) in no event will Executive be entitled to severance benefits under both Section 5 and Section 6 of this Agreement, and (ii) if the Company
has commenced providing severance pay and benefits to Executive under Section 5 prior to the date that Executive becomes eligible to receive severance pay and benefits under this Section 6, the severance pay and benefits previously provided to
Executive under Section 5 shall reduce the severance pay and benefits to be provided under this Section 6. 

  
 3 

 7. Potential Post-Employment Consulting. The Company presently anticipates offering Executive
the opportunity to be engaged by the Company for a limited period of time as an hourly consultant following the Date of Termination. Details of any post-employment consulting will be provided to Executive prior to the Date of Termination, and
Executive’s engagement as a consultant would be subject to Executive entering into a consulting services agreement (“Consulting Services Agreement”) with the Company. Any consulting services would be limited to no more than 20%
of Executive’s average level of services performed in the thirty-six (36) months prior to the Date of Termination. 
 8. Equity. Subject
to Section 6 and the terms of any Consulting Services Agreement (if applicable), and except for the Acceleration Awards, which are subject to vesting under Section 5(c) of this Agreement, the stock options and other stock-based awards granted to
Executive under the Company’s stock option and incentive plan(s) and the applicable equity award agreements between the Company and Executive (collectively, the “Equity Documents”) that are unvested as of the Date of
Termination will cease vesting and terminate on the Date of Termination and be of no further force or effect; provided, however, and notwithstanding the foregoing, the termination of the Time-Based Equity Awards shall be delayed until the earlier of
(i) a Change in Control, at which time the Time-Based Equity Awards shall immediately accelerate and become fully vested and exercisable or nonforfeitable pursuant to Section 6 or (ii) the date immediately following the three (3) month anniversary
of the Date of Termination, at which time the unvested portion of the Time-Based Equity Awards will terminate and be of no further force or effect. For the avoidance of doubt, no additional time-based vesting will occur after the Date of
Termination. Executive may exercise his vested stock options in accordance with the Equity Documents. For the avoidance of any doubt, the portion of the stock options granted on May 14, 2019 (the “May 2019 Grant”) that are vested as
of the Date of Termination and/or that accelerate pursuant to this Agreement may be exercised until the two-year anniversary of the Date of Termination for so long as such stock options remain outstanding. The portion of the Acceleration Awards that
are not part of the May 2019 Grant and all other vested options may be exercised during the three (3) months immediately following the Date of Termination. Notwithstanding the foregoing, if Executive enters into a Consulting Services Agreement and
performs post-employment consulting services for the Company, Executive will continue to have a “service relationship” with the Company following the Date of Termination and will continue to vest in his outstanding stock options until the
date of termination of the Consulting Services Agreement, and the two-year exercise period for the May 2019 Grant will commence as of such date. 

9. General Release. Executive irrevocably and unconditionally releases and forever discharges the Company, all of its affiliated and
related entities, its and their respective predecessors, successors and assigns, its and their respective employee benefit plans and the fiduciaries of such plans, and the current and former officers, directors, stockholders, employees, attorneys,
accountants, and agents of each of the foregoing in their official and personal capacities (collectively referred to as the “Releasees”) generally from all claims, demands, debts, damages and liabilities of every name and nature,
known or unknown (“Claims”) that, as of the date when Executive signs this Agreement, he has, ever had, now claims to have or ever claimed to have had against any or all of the Releasees. This release includes, without limitation,
the complete waiver and release of all Claims: relating to Executive’s employment by and termination of employment with the Company; arising out of or relating to the Employment 

  
 4 

 
Agreement or any other agreement between Executive and any of the Releasees; of breach of express or implied contract; of wrongful termination of employment whether in contract or tort; of
violation of public policy; of intentional, reckless, or negligent infliction of emotional distress; of breach of any express or implied covenant of employment, including the covenant of good faith and fair dealing; of interference with contractual
or advantageous relations, whether prospective or existing; of deceit or misrepresentation; of discrimination or retaliation under state, federal, or municipal law, including, without limitation, Title VII of the Civil Rights Act of 1964,
42 U.S.C. § 2000e et seq., as amended, the Americans with Disabilities Act, 42 U.S.C. § 12101 et seq., and the Ohio Civil Rights Act; of whistleblower retaliation; of fraud; under any other federal, state or
local statute, rule, ordinance, or regulation; of promissory estoppel or detrimental reliance; for wages, bonuses, incentive compensation, stock, stock options, vacation pay, severance allowances or entitlements, and any other compensation or
benefits, either under Ohio wage law, or otherwise; of slander, libel, defamation, disparagement, intentional infliction of emotional distress, personal injury, negligence, or other torts; for damages or other remedies of any sort, including,
without limitation, compensatory damages, punitive damages, injunctive relief, attorneys’ fees, experts’ fees, medical fees or expenses, costs, and disbursements. Executive understands that this general release of Claims includes, without
limitation, any and all Claims related to Executive’s employment by the Company (including without limitation, any Claims against the Company in respect of any stock-based awards of any kind) and the termination of his employment, and all
Claims in his capacity as a Company stockholder arising up to and through the date that Executive enters into this Agreement. Executive understands that this general release does not extend to any rights or Claims that may arise out of acts or
events that occur after the date on which Executive signs this Agreement or to Claims that cannot be released as a matter of law. This release does not affect Executive’s rights or obligations under this Agreement, nor shall it affect
Executive’s rights, if any, to unemployment compensation benefits or to workers’ compensation. Executive agrees not to accept damages of any nature, other equitable or legal remedies for Executive’s own benefit or attorney’s fees
or costs from any of the Releasees with respect to any Claim released by this Agreement. Executive represents that he has not assigned to any third party and has not filed with any agency or court any Claim released by this Agreement. Further, this
release does not affect Executive’s rights to any indemnification and defense he has with the Company. 
 10. Return of Property.
Executive agrees to return to the Company all Company property, including, without limitation, computer equipment, software, keys and access cards, credit cards, files and any documents (including computerized data and any copies made of any
computerized data or software) containing information concerning the Company, its business or its business relationships. After returning all Company property, Executive agrees to delete and finally purge any duplicates of files or documents that
may contain Company or customer information from any non-Company computer or other device that remains Executive’s property after the Date of Termination. 

Notwithstanding the foregoing, if this Agreement becomes effective and Executive satisfies the Conditions, then the Company will permit him to
keep his Company laptop following the Date of Termination, provided that all Company information is removed from the laptop and Executive works cooperatively with the Company’s IT group to ensure such removal. In addition, if this Agreement
becomes effective and Executive satisfies the Conditions, the Company will permit Executive to keep his Company cell phone and phone number and buy out or transfer the remaining cost of the phone to your personal account following the Date of
Termination. 

  
 5 

 11. Non-Disparagement. Subject to Section 14, Executive agrees not to make any disparaging
statements (whether written, oral, through social or electronic media or otherwise) concerning the Company or any of the Releasees. Executive further agrees not to take any actions or conduct himself in any way that would reasonably be expected to
affect adversely the reputation or goodwill of the Company or any of the Releasees. 
 12. Continuing Obligations; Termination of Payments; Injunctive
Relief. Executive acknowledges that his right to the payments and benefits set forth in this Agreement are conditioned on his full compliance with the provisions in Section 7 of the Employment Agreement (“Section 7 of the Employment
Agreement”), including without limitation the obligation to provide post-employment litigation and regulatory cooperation and the obligations under Section 6 of the Prior Agreement (the “Restrictive Covenants”), which was
incorporated by reference into the Employment Agreement. Section 7 of the Employment Agreement and the Restrictive Covenants are incorporated by reference as material terms of this Agreement, and, together with Sections 10 and 11 of this Agreement
shall be referred to as the “Continuing Obligations”, provided, however, that the Company hereby waives the post-employment non-competition obligation set forth in the Restrictive Covenants, and such provision is not included in the
definition of Continuing Obligations set forth above. In the event that Executive fails to comply with any of the Continuing Obligations, in addition to any other legal or equitable remedies it may have for such breach, the Company shall have the
right to end Executive’s employment if he remains employed at such time and/or to terminate payments provided under this Agreement other than the Accrued Benefit. Such termination in the event of a breach by Executive of the Continuing
Obligations shall not affect the general release in Section 9 or Executive’s obligation to comply with the Continuing Obligations and shall be in addition to, and not in lieu of, the Company’s rights to other legal and equitable remedies
that the Company may have. Further, Executive agrees that it would be difficult to measure any harm caused to the Company that might result from any breach by Executive of any of the Continuing Obligations and that, in any event, money damages would
be an inadequate remedy for any such breach. Accordingly, Executive agrees that if he breaches, or proposes to breach, any portion of the Continuing Obligations the Company shall be entitled, in addition to all other remedies it may have, to an
injunction or other appropriate equitable relief to restrain any such breach, without showing or proving any actual damage to the Company and without the necessity of posting a bond and to recover the Company’s attorneys’ fees and costs
associated with any such breach by Executive. 
 13. Absence of Reliance. This Agreement is a legally binding document and Executive’s
signature will commit Executive to its terms. In signing this Agreement, Executive agrees that he is not relying upon any promise or representations made by anyone at or on behalf of the Company. Executive further agrees that he has carefully read
and fully understands all of the provisions of this Agreement and that Executive is voluntarily and knowingly entering into this Agreement. 

  
 6 

 14. Protected Disclosures; Defend Trade Secrets Act. Nothing in this Agreement or
otherwise limits Executive’s: (i) obligation to testify truthfully in any legal proceeding; (ii) right to file a charge, claim or complaint with any federal agency (such as the Equal Employment Opportunity Commission) or any state or local
governmental agency or commission (together, a “Government Agency”), provided that Executive waives any right to monetary or other individualized relief (either individually or as part of any collective or class action); provided
further that nothing in this Agreement limits any right you may have to receive a whistleblower award or bounty for information provided to the Securities and Exchange Commission; or (iii) ability to communicate with any Government Agency or
otherwise participate in any investigation or proceeding that may be conducted by any Government Agency. Executive is hereby notified in accordance with the Defend Trade Secrets Act of 2016 that Executive will not be held criminally or civilly
liable under any federal or state trade secret law for the disclosure of a trade secret that: (i) is made (A) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney; and (B) solely for the
purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. 

15. Effective Date. To accept this Agreement, Executive must return a signed, unmodified original or PDF copy of this Agreement so that it is
received by Gina Marek, Vice President of Finance (gmarek@aerpio.com) on or before 5:00pm EST on February 9, 2021. This Agreement shall become effective upon execution by both Parties (the “Effective Date”). 

16. Enforceability. Executive acknowledges that, if any portion or provision of this Agreement or the Continuing Obligations shall to any extent
be declared illegal or unenforceable by a court of competent jurisdiction, then the remainder other than those as to which it is so declared illegal or unenforceable, shall not be affected thereby, and each portion and provision shall be valid and
enforceable to the fullest extent permitted by law. 
 17. Entire Agreement. This Agreement along with the Continuing Obligations (including,
for the avoidance of doubt, the Restrictive Covenants) constitute the entire agreement between Executive and the Company concerning Employee’s relationship with the Company, and supersedes and replaces any and all prior agreements and
understandings between the Parties concerning the Employee’s relationship with the Company including, without limitation, the Employment Agreement, provided that the Equity Documents, subject to the terms of this Agreement, Section 8 of the
Employment Agreement (Arbitration of Disputes) and any and all formal written indemnification agreements shall continue to be in full force and effect. 

18. Waiver; Amendment. No waiver of any provision of this Agreement, including the Continuing Obligations, shall be effective unless made in
writing and signed by the waiving party. The failure of either Party to require the performance of any term or obligation of this Agreement or the Continuing Obligations, or the waiver by either Party of any breach of this Agreement or the
Continuing Obligations shall not prevent any subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach. This Agreement may not be modified or amended except in a writing signed by both Executive and a duly
authorized officer of the Company. 

  
 7 

 19. Taxes. The Company shall undertake to make deductions, withholdings and tax reports
with respect to payments and benefits under this Agreement and in connection with other compensation matters to the extent that it reasonably and in good faith determines that it is required to make such deductions, withholdings and tax reports.
Payments under this Agreement shall be in amounts net of any such deductions or withholdings. Nothing in this Agreement shall be construed to require the Company to make any payments to compensate Executive for any adverse tax effect associated with
any payments or benefits made to Executive in connection with Executive’s employment with the Company. 
 20. Section 409A. Anything in
this Agreement to the contrary notwithstanding, if at the time of Executive’s separation from service within the meaning of Section 409A of the Code, the Company determines that Executive is a “specified employee” within the meaning
of Section 409A(a)(2)(B)(i) of the Code, then to the extent any payment or benefit that Executive becomes entitled to under this Agreement on account of Executive’s separation from service would be considered deferred compensation otherwise
subject to the 20 percent additional tax imposed pursuant to Section 409A(a) of the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, such payment shall not be payable and such benefit shall not be provided until the date
that is the earlier of (A) six months and one day after Executive’s separation from service, or (B) Executive’s death. If any such delayed cash payment is otherwise payable on an installment basis, the first payment shall include a
catch-up payment covering amounts that would otherwise have been paid during the six-month period but for the application of this provision, and the balance of the installments shall be payable in accordance with their original schedule. To the
extent that any payment or benefit described in this Agreement constitutes “non-qualified deferred compensation” under Section 409A of the Code, and to the extent that such payment or benefit is payable upon Executive’s
termination of employment, then such payments or benefits shall be payable only upon Executive’s “separation from service.” The determination of whether and when a separation from service has occurred shall be made in accordance with
the presumptions set forth in Treasury Regulation Section 1.409A-1(h). The parties intend that this Agreement will be administered in accordance with Section 409A of the Code. To the extent that any provision of this Agreement is ambiguous as
to its compliance with Section 409A of the Code, the provision shall be read in such a manner so that all payments hereunder comply with Section 409A of the Code. Each payment pursuant to this Agreement is intended to constitute a separate payment
for purposes of Treasury Regulation Section 1.409A-2(b)(2). The parties agree that this Agreement may be amended, as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules
and regulations in order to preserve the payments and benefits provided hereunder without additional cost to either party. The Company makes no representation or warranty and shall have no liability to Executive or any other person if any provisions
of this Agreement are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the conditions of, such Section. 

21. Acknowledgment of Wage and Other Payments. Executive acknowledges and represents that, except as expressly provided in this Agreement,
Executive has been paid all wages, bonuses, compensation, benefits and other amounts that any of the Releasees has ever owed to Executive. Executive is not entitled to any bonus, incentive compensation or other compensation except as specifically
set forth in this Agreement. 

  
 8 

 22. Governing Law; Interpretation. This Agreement shall be interpreted and enforced
under the laws of the State of Ohio without regard to conflict of law principles. In the event of any dispute, this Agreement is intended by the Parties to be construed as a whole, to be interpreted in accordance with its fair meaning, and not to be
construed strictly for or against either Party or the “drafter” of all or any portion of this Agreement. This Agreement will be binding on the Company’s successors and assigns. Further, if Executive dies before receiving his entire
severance payments, the remaining payments will be paid to his estate. 
 23. Counterparts. This Agreement may be executed in any number of
counterparts, each of which when so executed and delivered shall be taken to be an original, but all of which together shall constitute one and the same document. Electronic and pdf signatures shall be deemed to be of equal force and effect as
originals.

      SUBSCRIPTION AGREEMENT

      

      

      Sandbridge Acquisition Corporation

      1999 Avenue of the Stars, Suite 2088

      Los Angeles, CA 90067

      

      

      Ladies and Gentlemen:

      

      

      This Subscription Agreement (this “Subscription Agreement”) is being entered into by and between Sandbridge Acquisition Corporation, a Delaware corporation (“Sandbridge”), and the
        undersigned subscriber (the “Investor”), as of the date set forth on Sandbridge’s signature page hereto, in connection with the Business Combination Agreement, to be entered into concurrently herewith (as may be amended, supplemented or
        otherwise modified from time to time, the “Transaction Agreement”), by and among Sandbridge, Owlet Baby Care Inc., a Delaware corporation (the “Company”), Project Olympus Merger Sub, Inc., a Delaware corporation (“Merger Sub”),
        pursuant to which, among other things, Merger Sub will merge with and into the Company, with the Company as the surviving company in the merger and, after giving effect to such merger, becoming a wholly-owned subsidiary of Sandbridge, on the terms
        and subject to the conditions therein (such merger, the “Transaction”). In connection with the Transaction, Sandbridge is seeking commitments from interested investors to purchase, prior to the closing of the Transaction, shares of
        Sandbridge’s Class A common stock, par value $0.0001 per share (the “Shares”), in a private placement for a purchase price of $10.00 per share (the “Per Share Purchase Price”). On or about the date of this Subscription Agreement,
        Sandbridge is entering into subscription agreements (the “Other Subscription Agreements”) with certain other investors (the “Other Investors” and together with the Investor, the “Investors”), severally and not jointly, pursuant
        to which the Investors, severally and not jointly, have agreed to purchase on the closing date of the Transaction, inclusive of the Shares subscribed for by the Investor, an aggregate amount of up to thirteen (13) million Shares, at the Per Share
        Purchase Price.

      

      

      The aggregate purchase price to be paid by the Investor for the subscribed Shares (as set forth on the signature page hereto) is referred to herein as the “Subscription Amount.”

      

      

      In connection therewith, and in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, set forth herein, and intending to be legally
        bound hereby, each of the Investor and Sandbridge acknowledges and agrees as follows:

      

      

      1. Subscription. The Investor hereby subscribes for and agrees to purchase from Sandbridge, and Sandbridge agrees to issue and sell to the Investor, the number of Shares set forth on the
        signature page of this Subscription Agreement on the terms and subject to the conditions provided for herein.

      
        
          

      

      2. Closing. The closing of the sale of the Shares contemplated hereby (the “Closing”) is contingent upon the substantially concurrent consummation of the
        Transaction. The Closing shall occur on the date of, and substantially concurrently with and conditioned upon the effectiveness of, the Transaction. Upon (a) satisfaction or waiver of the conditions set forth in Section 3 below and (b) delivery of
        written notice from (or on behalf of) Sandbridge to the Investor (the “Closing Notice”), that Sandbridge reasonably expects all conditions to the closing of the Transaction to be satisfied or waived on a date that is not less than five (5)
        business days from the date on which the Closing Notice is delivered to the Investor, the Investor shall deliver to Sandbridge, two (2) business days prior to the closing date specified in the Closing Notice (the “Closing Date”), the
        Subscription Amount by wire transfer of United States dollars in immediately available funds to the account(s) specified by Sandbridge in the Closing Notice to be held in escrow until Closing. On the Closing Date, Sandbridge shall issue a number of
        Shares to the Investor set forth on the signature page to this Subscription Agreement, free and clear of any liens or restrictions (other than those arising under state and federal securities laws), and subsequently cause such Shares to be
        registered in book entry form in the name of the Investor on Sandbridge’s share register; provided, however, that Sandbridge’s obligation to issue the Shares to the Investor is contingent upon Sandbridge having received the Subscription Amount in
        full accordance with this Section 2.  In the event that the consummation of the Transaction does not occur within ten (10) business days after the anticipated Closing Date specified in the Closing Notice, Sandbridge shall promptly (but in no event
        later than twelve (12) business days after the anticipated Closing Date specified in the Closing Notice) return the funds so delivered by the Investor to Sandbridge by wire transfer in immediately available funds to the account specified by the
        Investor. Notwithstanding such return, (i) failure to close on the Closing Date contained in the Closing Notice shall not, by itself, be deemed to be a failure of any of the conditions to Closing set forth in this Section 2 to be satisfied or
        waived, and (ii) Investor shall remain obligated to (A) redeliver funds to Sandbridge following Sandbridge’s delivery to Investor of a new Closing Notice with a new Closing Date in accordance with this Subscription Agreement and (B) consummate the
        Closing upon satisfaction of the conditions set forth in Section 3, subject to termination of this Agreement in accordance with Section 8 below. For purposes of this Subscription Agreement, “business day” shall mean a day, other than a Saturday or
        Sunday, on which commercial banks in New York, New York are open for the general transaction of business.

      

      

      3. Closing Conditions.

      

      

      a. The obligation of the parties hereto to consummate the purchase and sale of the Shares pursuant to this Subscription Agreement is subject to the following conditions:

      

      

      (i) no applicable governmental authority shall have issued, enforced or entered any judgment or order, which is then in effect and has the effect of making the consummation of
        the transactions contemplated hereby illegal or otherwise restraining or prohibiting consummation of the transactions contemplated hereby; and

      
        
          

      

      (ii) (A) all conditions precedent to the closing of the Transaction under the Transaction Agreement shall have been satisfied (as determined by the parties to the Transaction
        Agreement and other than those conditions under the Transaction Agreement which, by their nature, are to be satisfied at the closing of the Transaction, including to the extent that any such condition is dependent upon the consummation of the
        purchase and sale of the Shares pursuant to this Subscription Agreement) or waived and (B) the closing of the Transaction shall be scheduled to occur concurrently with or on the same date as the Closing; and

      

      

      (iii) no suspension  of the qualification of the Shares for offering or sale or trading in any jurisdiction in the United States, or initiation of any proceedings for any of such
        purposes, shall have occurred and be continuing.

      

      

      b. The obligation of Sandbridge to consummate the issuance and sale of the Shares pursuant to this Subscription Agreement shall be subject to the condition that all representations and warranties
        of the Investor contained in this Subscription Agreement are true and correct in all material respects at and as of the Closing Date, and consummation of the Closing shall constitute a reaffirmation by the Investor of each of the representations
        and warranties of the Investor contained in this Subscription Agreement as of the Closing Date.

      

      

      c. The obligation of the Investor to consummate the purchase of the Shares pursuant to this Subscription Agreement shall be subject to the following conditions:

      

      

      (i) no amendment, modification or waiver of the Transaction Agreement (as the same exists on the date of this Subscription Agreement) shall have occurred without the Investor’s
        written consent that would materially and adversely affect the economic benefits that Investor would reasonably expect to receive under this Subscription Agreement;

      

      

      (ii) all representations and warranties of Sandbridge contained in this Subscription Agreement shall be true and correct as of the Closing Date (other than those representations
        and warranties expressly made as of an earlier date, which shall be true and correct as of such date), except, in the case of this clause (ii), for any failure of any such representation and warranty to be so true and correct (without giving effect
        to any qualification by materiality or Material Adverse Effect contained therein) that would not, individually or in the aggregate, reasonably be expected to have a
        Material Adverse Effect;

      

      

      (iii) Sandbridge shall have performed, satisfied and complied in all material respects with all covenants, agreements and conditions required by the Subscription Agreement to be
        performed, satisfied or complied with by it at or prior to the Closing; provided, that this condition shall be deemed satisfied unless written notice of such non-compliance is provided by the Investor to Sandbridge, and Sandbridge fails to cure
        such non-compliance in all material respects within five (5) business days of receipt of such notice;

      
        
          

      

      (iv) there shall have been no amendment, waiver, or modification to the other Subscription Agreements that materially economically benefits the Other Investor unless the Investor
        has been offered substantially the same benefits; and

      

      

      (vi) the Stock Exchange (as defined herein) shall have conditionally authorized, subject to official notice of issuance, the listing of the Shares.

      

      

      4. Further Assurances. Prior to or at the Closing, the Investor shall deliver all such other information as is reasonably requested in order for Sandbridge to issue the Shares to the
        Investor.

      

      

      5. Sandbridge Representations and Warranties. Sandbridge represents and warrants to the Investor that:

      

      

      a. Sandbridge is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware. Sandbridge has all corporate power and authority to own, lease and
        operate its properties and conduct its business as presently conducted and to enter into, deliver and perform its obligations under this Subscription Agreement.

      

      

      b. As of the Closing Date, the Shares will be duly authorized and, when issued and delivered to the Investor against full payment therefor in accordance with the terms of this Subscription
        Agreement, the Shares will be validly issued, fully paid and non-assessable and will not have been issued in violation of or subject to any preemptive or similar rights created under Sandbridge’s certificate of incorporation, bylaws or under the
        General Corporation Law of the State of Delaware.

      

      

      c. This Subscription Agreement has been duly authorized, executed and delivered by Sandbridge and, assuming that this Subscription Agreement constitutes the valid and binding agreement of the
        Investor, this Subscription Agreement is enforceable against Sandbridge in accordance with its terms, except as may be limited or otherwise affected by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other laws
        relating to or affecting the rights of creditors generally, or (ii) principles of equity, whether considered at law or equity.

      

      

      d. The execution and delivery of this Subscription Agreement and the issuance and sale of the Shares and the compliance by Sandbridge with all of the provisions of this Subscription Agreement and
        the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or
        encumbrance upon any of the property or assets of Sandbridge or any of its subsidiaries pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which Sandbridge or any
        of its subsidiaries is a party or by which Sandbridge or any of its subsidiaries is bound or to which any of the property or assets of Sandbridge is subject that would reasonably be expected to have a material adverse effect on the business,
        financial condition or results of operations of Sandbridge and its subsidiaries, taken as a whole and assuming for this purpose the consummation of the Transaction (a “Material Adverse Effect”) or materially affect the validity of the Shares
        or the legal authority of Sandbridge to comply in all material respects with the terms of this Subscription Agreement; (ii) result in any violation of the provisions of the organizational documents of Sandbridge; or (iii) result in any violation of
        any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over Sandbridge or any of their properties that would reasonably be expected to have a Material Adverse
        Effect or materially affect the validity of the Shares or the legal authority of Sandbridge to comply in all material respects with this Subscription Agreement.

      
        
          

      

      e. As of their respective dates, all reports (the “SEC Reports”) required to be filed by Sandbridge with the U.S. Securities and Exchange Commission (the “SEC”) complied in all
        material respects with the applicable requirements of the Securities Act of 1933, as amended, (the “Securities Act”) and the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules and regulations of the SEC
        promulgated thereunder, and none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light
        of the circumstances under which they were made, not misleading. Sandbridge has timely filed each SEC Report, statement, schedule, prospectus and registration statement that Sandbridge was required to file with the SEC since the effective date of
        its initial registration statement relating to the initial public offering of its securities. The financial statements of Sandbridge included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules
        and regulations of the SEC with respect thereto as in effect at the time of filing and fairly present in all material respects the financial position of Sandbridge as of and for the dates thereof and the results of operations and cash flows for the
        periods then ended, subject, in the case of unaudited statements, to normal, year-end audit adjustments. A copy of each SEC Report is available to the Investor via the SEC’s EDGAR system. There are no outstanding or unresolved comments in comment
        letters received by Sandbridge from the staff of the Division of Corporation Finance of the SEC with respect to any of the SEC Reports.

      

      

      f. Other than the Other Subscription Agreements, the Transaction Agreement and any other agreement expressly contemplated by the Transaction Agreement, Sandbridge has not entered into any side
        letter or similar agreement with any Other Investor in connection with such investor’s investment in the Shares, and no Other Subscription Agreement includes terms and conditions that are materially more favorable to any such Other Investor than
        Investor hereunder, and such Other Subscription Agreements reflect the same Per Share Purchase Price. The Other Subscription Agreements have not been amended in any material respect following the date of this Subscription Agreement.

      

      

      g. Sandbridge is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or
        other governmental authority, self-regulatory organization or other person in connection with the execution, delivery and performance by Sandbridge of this Subscription Agreement (including, without limitation, the issuance of the Shares), other
        than (i) filings with the SEC, (ii) filings required by applicable state securities laws, (iii) filings required by the New York Stock Exchange (the “Stock Exchange”), and (iv) the failure of which to obtain would not have, individually or
        in the aggregate, a Material Adverse Effect.

      
        
          

      

      h. As of the date of this Subscription Agreement, the authorized capital stock of Sandbridge consists of 1,000,000 shares of Preferred Stock, 100,000,000 shares of Class A common stock (“Class A
          Stock”), and 10,000,000 shares of Class B common stock (the “Class B Stock”), each par value $0.0001 per share. As of the date of this Subscription Agreement, (i) no Preferred Shares are issued and outstanding, (ii) 23,000,000 shares
        of Class A Stock are issued and outstanding, (iii) 5,750,000 shares of Class B Stock are issued and outstanding and (iv) 11,500,000 redeemable warrants and 6,600,000 private placement warrants to acquire shares of Class A Stock are outstanding. All
        (A) issued and outstanding shares of Class A Stock and Class B Stock have been duly authorized, are fully paid and are non-assessable and (B) outstanding warrants have been duly authorized. Except as set forth above, and except for any equity
        interests issued upon conversion or exercise of any of the equity interests set forth above in accordance with their terms, and other than pursuant to the Other Subscription Agreements, the Transaction Agreement and the other agreements and
        arrangements referred to therein, as of the date hereof, there are no outstanding options, warrants or other rights to subscribe for, purchase or acquire from Sandbridge any shares of Class A Stock, Class B Stock or other equity interests in
        Sandbridge, or securities convertible into or exchangeable or exercisable for such equity interests. As of the date hereof, Sandbridge has no subsidiaries, other than Merger Sub, and does not own, directly or indirectly, interests or investments
        (whether equity or debt) in any person, whether incorporated or unincorporated. There are no stockholder agreements, voting trusts or other agreements or understandings to which Sandbridge is a party or by which it is bound relating to the voting
        of any securities of Sandbridge, other than (1) as set forth in the SEC Reports and (2) as contemplated by the Transaction Agreement. There are no securities or instruments issued by Sandbridge containing anti-dilution provisions that will be
        triggered by the issuance of (i) the Shares pursuant to this Subscription Agreement or (ii) the Shares to be issued pursuant to any Other Subscription Agreement, in each case, that have not been or will not be validly waived on or prior to the
        Closing Date.

      

      

      i. The issued and outstanding shares of Class A Stock are registered pursuant to Section 12(b) of the Exchange Act, and are listed for trading on the Stock Exchange. As of the date hereof, there is
        no suit, action, proceeding or investigation pending or, to the knowledge of Sandbridge, threatened against Sandbridge by the Stock Exchange or the SEC, respectively, to prohibit or terminate the listing of the Class A Stock, or to deregister the
        Class A Stock. Sandbridge has taken no action that is designed to terminate the registration of the shares of Class A Stock under the Exchange Act.

      

      

      j. Assuming the accuracy of the Investor’s representations and warranties set forth in Section 6, no registration under the Securities Act is required for the offer and sale of the Shares by
        Sandbridge to the Investor hereunder. The Shares (i) were not offered by any form of general solicitation or general advertising and (ii) are not being offered in a manner involving a public offering under, or in a distribution in violation of, the
        Securities Act, or any state securities laws.

      

      

      k. Except for such matters as have not had and would not have, individually or in the aggregate, a Material Adverse Effect, there is no (i) action, suit, claim or other proceeding, in each case by
        or before any governmental authority pending, or, to the knowledge of Sandbridge, threatened against Sandbridge or (ii) judgment, decree, injunction, ruling or order of any governmental entity or arbitrator outstanding against Sandbridge.

      
        
          

      

      l. Sandbridge is in compliance with all applicable laws, except where such non-compliance would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.
        Sandbridge has not received any written communication from a governmental authority that alleges that Sandbridge is not in compliance with or is in default or violation of any applicable law, except where such non-compliance, default or violation
        would not be reasonably expected to have, individually or in the aggregate, a Material Adverse Effect.

      

      

      m. Other than the Placement Agents (as defined below), Sandbridge has not engaged any broker, finder, commission agent, placement agent or arranger in connection with the sale of the Shares, and
        Sandbridge is not under any obligation to pay any broker’s fee or commission in connection with the sale of the Shares other than to the Placement Agents.

      

      

      n. Sandbridge is not a United States real property holding corporation (as defined in Section 897(c)(2) of the Internal Revenue Code of 1986, as amended).

      

      

      o. No part of the proceeds of the Subscription Amount will be used, directly or indirectly, for any purpose that would breach the Foreign Corrupt Practices Act of 1977 or the U.K. Bribery Act 2010,
        each as may be amended, or similar law of any other relevant jurisdiction, or the rules or regulations thereunder, or for any purpose that would breach any U.S. or other applicable anti-money laundering or economic sanctions laws.

      

      

      p. Sandbridge is not required to be registered as, and is not an affiliate of, and immediately following the Closing (including the closing of the Transaction) will not be required to register as,
        an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

      

      

      r. Sandbridge  acknowledges that, notwithstanding anything herein to the contrary, the Shares may be pledged by Investor in connection with a bona fide margin agreement, provided such pledge shall
        be (i) pursuant to an available exemption from the registration requirements of the Securities Act or (ii) pursuant to, and in accordance with, a registration statement that is effective under the Securities Act at the time of such pledge, and the
        Investor effecting a pledge of Shares shall not be required to provided Sandbridge with any notice thereof; provided, however, that neither Sandbridge or its counsel shall be required to take any action (or refrain from taking any action) in
        connection with any such pledge.

      

      

      6. Investor Representations and Warranties. The Investor represents and warrants to Sandbridge that:

      

      

      a. The Investor (i) is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act), an institutional “accredited investor” (within the meaning of Rule 501(a) under the
        Securities Act) or a “qualified purchaser” (as defined in Section 2(a)(51)(A) of the Investment Company Act of 1940), in each case, satisfying the applicable requirements set forth on Schedule A, (ii) is acquiring the Shares only for his,
        her or its own account and not for the account of others, or if the Investor is subscribing for the Shares as a fiduciary or agent for one or more investor accounts, the Investor has full investment discretion with respect to each such account, and
        the full power and authority to make the acknowledgements, representations and agreements herein on behalf of each owner of each such account, and (iii) is not acquiring the Shares with a view to, or for offer or sale in connection with, any
        distribution thereof in violation of the Securities Act (and shall provide the requested information set forth on Schedule A). The Investor is not an entity formed for the specific purpose of acquiring the Shares.

      
        
          

      

      b. The Investor acknowledges and agrees that the Shares are being offered in a transaction not involving any public offering within the meaning of the Securities Act and that the Shares have not
        been registered under the Securities Act. The Investor acknowledges and agrees that the Shares may not be offered, resold, transferred, pledged or otherwise disposed of by the Investor absent an effective registration statement under the Securities
        Act except (i) to Sandbridge or a subsidiary thereof, (ii) to non-U.S. persons pursuant to offers and sales that occur outside the United States within the meaning of Regulation S under the Securities Act or (iii) pursuant to another applicable
        exemption from the registration requirements of the Securities Act, and in each of clauses (i) and (iii) in accordance with any applicable securities laws of the states and other jurisdictions of the United States, and that any certificates
        representing the Shares shall contain a restrictive legend to such effect. The Investor acknowledges and agrees that the Shares will be subject to the foregoing transfer restrictions and, as a result of these transfer restrictions, the Investor may
        not be able to readily offer, resell, transfer, pledge or otherwise dispose of the Shares and may be required to bear the financial risk of an investment in the Shares for an indefinite period of time. The Investor acknowledges and agrees that the
        Shares will not be eligible for offer, resale, transfer, pledge or disposition pursuant to Rule 144 promulgated under the Securities Act until at least one year from the date that Sandbridge files a Current Report on Form 8-K following the Closing
        Date that includes the “Form 10” information required under applicable SEC rules and regulations. The Investor acknowledges and agrees that it has been advised to consult legal counsel prior to making any offer, resale, transfer, pledge or
        disposition of any of the Shares.

      

      

      c. The Investor acknowledges and agrees that the Investor is purchasing the Shares from Sandbridge. The Investor further acknowledges that there have been no representations, warranties, covenants
        and agreements made to the Investor by or on behalf of Sandbridge, the Company, any of their respective officers and directors, or any other person or entity, expressly or by implication, other than those representations, warranties, covenants and
        agreements of Sandbridge expressly set forth in this Subscription Agreement.

      

      

      d. The Investor’s acquisition and holding of the Shares will not constitute or result in a non-exempt prohibited transaction under Section 406 of the Employee Retirement Income Security Act of
        1974, as amended, Section 4975 of the Internal Revenue Code of 1986, as amended, or any applicable similar law.

      

      

      e. The Investor acknowledges and agrees that the Investor has received such information as the Investor deems necessary in order to make an investment decision with respect to the Shares,
        including, with respect to Sandbridge, the Transaction and the business of the Company and its subsidiaries. Without limiting the generality of the foregoing, the Investor acknowledges that he, she or it has reviewed the SEC Reports. The Investor
        acknowledges and agrees that the Investor and the Investor’s professional advisor(s), if any, have had the full opportunity to ask such questions, receive such answers and obtain such information as the Investor and such Investor’s professional
        advisor(s), if any, have deemed necessary to make an investment decision with respect to the Shares.

      
        
          

      

      f. The Investor became aware of this offering of the Shares solely by means of direct contact between the Investor and Sandbridge, the Company or a representative of Sandbridge or the Company, and
        the Shares were offered to the Investor solely by direct contact between the Investor and Sandbridge, the Company or a representative of Sandbridge or the Company. The Investor did not become aware of this offering of the Shares, nor were the
        Shares offered to the Investor, by any other means. The Investor acknowledges that the Shares (i) were not offered to the Investor by any form of general solicitation or general advertising and (ii) are not being offered to the Investor in a manner
        involving a public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws. The Investor acknowledges that it is not relying upon, and has not relied upon, any statement, representation or warranty
        made by any person, firm or corporation (including, without limitation, Sandbridge, the Company, the Placement Agents (defined below), any of their respective affiliates or any control persons, officers, directors, employees, partners, agents or
        representatives of any of the foregoing), other than the representations and warranties of Sandbridge contained in Section 5 of this Subscription Agreement, in making its investment or decision to invest in Sandbridge. The Investor acknowledges
        that certain information provided by the Company was based on projections, and such projections were prepared based on assumptions and estimates that are inherently uncertain and are subject to a wide variety of significant business, economic and
        competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projections.

      

      

      g. The Investor acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Shares, including those set forth in Sandbridge’s filings with the SEC.
        The Investor has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Shares, and the Investor has sought such accounting, legal and tax advice as the Investor
        has considered necessary to make an informed investment decision.

      

      

      h. Alone, or together with any professional advisor(s), the Investor has analyzed and considered the risks of an investment in the Shares and the Investor is able at this time and in the
        foreseeable future to bear the economic risk of a total loss of the Investor’s investment in Sandbridge. The Investor acknowledges specifically that a possibility of total loss exists.

      

      

      i. In making its decision to purchase the Shares, the Investor has relied solely upon independent investigation made by the Investor. Neither Sandbridge nor any of its affiliates have offered the
        Investor any tax advice relating to Investor’s investment in the Shares, or made any representations, warranties or guarantees regarding the tax consequences of Investor’s investment in the Shares.

      

      

      j. The Investor acknowledges and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of the Shares or made any findings or determination as to the fairness
        of this investment.

      

      

      k. The Investor, if not an individual, has been duly formed or incorporated and is validly existing and is in good standing under the laws of its jurisdiction of formation or incorporation, with
        power and authority to enter into, deliver and perform its obligations under this Subscription Agreement.

      
        
          

      

      l. The execution, delivery and performance by the Investor of this Subscription Agreement are within the powers of the Investor, have been duly authorized and will not constitute or result in a
        breach or default under or conflict with any order, ruling or regulation of any court or other tribunal or of any governmental commission or agency, or any agreement or other undertaking, to which the Investor is a party or by which the Investor is
        bound, and, if the Investor is not an individual, will not violate any provisions of the Investor’s organizational documents, including, without limitation, its incorporation or formation papers, bylaws, indenture of trust or partnership or
        operating agreement, as may be applicable. The signature on this Subscription Agreement is genuine, and the signatory has been duly authorized to execute the same, and this Subscription Agreement constitutes a legal, valid and binding obligation of
        the Investor, enforceable against the Investor in accordance with its terms except as may be limited or otherwise affected by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other laws relating to or affecting the
        rights of creditors generally, and (ii) principles of equity, whether considered at law or equity.

      

      

      m. The Investor is not (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons administered by the U.S. Treasury Department’s Office of Foreign Assets Control
        (“OFAC”) or in any Executive Order issued by the President of the United States and administered by OFAC (“OFAC List”), or a person or entity prohibited by any OFAC sanctions program, (ii) a Designated National as defined in the Cuban
        Assets Control Regulations, 31 C.F.R. Part 515, or (iii) a non-U.S. shell bank or providing banking services indirectly to a non-U.S. shell bank. If the Investor is a financial institution subject to the Bank Secrecy Act (31 U.S.C. Section 5311 et
        seq.), as amended by the USA PATRIOT Act of 2001, and its implementing regulations (collectively, the “BSA/PATRIOT Act”), the Investor maintains policies and procedures reasonably designed to comply with applicable obligations under the
        BSA/PATRIOT Act. To the extent required, it maintains policies and procedures reasonably designed for the screening of its investors against the OFAC sanctions programs, including the OFAC List. To the extent required by applicable law, the
        Investor maintains policies and procedures reasonably designed to ensure that the funds held by the Investor and used to purchase the Shares were legally derived.

      

      

      n. The Investor acknowledges that no disclosure or offering document has been provided to the Investor by Citigroup Global Markets Inc. and BofA Securities, Inc. or any of their respective
        affiliates (collectively, the “Placement Agents”) in connection with the offer and sale of the Shares.

      

      

      o. The Investor acknowledges that neither Placement Agent has, nor have any of their respective affiliates or any control persons, officers, directors, employees, partners, agents or
        representatives of any of the foregoing made any independent investigation with respect to Sandbridge, the Company or its subsidiaries or any of their respective businesses, or the Shares or the accuracy, completeness or adequacy of any information
        supplied to the Investor by Sandbridge.

      

      

      p. The Investor acknowledges that in connection with the issue and purchase of the Shares, neither Placement Agent has acted as the Investor’s financial advisor or fiduciary.

      

      

      q. The Investor will have sufficient funds to pay the Subscription Amount and consummate the purchase and sale of the Shares pursuant to this Subscription Agreement pursuant to Section 2.

      
        
          

      

      7. Registration Rights.

      

      

      (a) In the event that the Shares are not registered in connection with the consummation of the Transaction, Sandbridge agrees that, within thirty (30) calendar days after the
        Closing Date, it will file with the SEC (at its sole cost and expense) a registration statement registering the resale of the Shares (the “Registration Statement”), and it shall use its commercially reasonable efforts to have the
        Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earliest of (i) sixty (60) calendar days (or ninety (90) calendar days if the SEC notifies Sandbridge that it will “review” the
        Registration Statement) following the Closing Date and (ii) five (5) business days after Sandbridge is notified (orally or in writing, whichever is earlier) by the SEC that the Registration Statement will not be “reviewed” or will not be subject to
        further review. Sandbridge agrees to cause such Registration Statement, or another shelf registration statement that includes the Shares to be sold pursuant to this Subscription Agreement, to remain effective until the earliest of (x) the third
        anniversary of the Closing, (y) the date on which the Investor ceases to hold any Shares issued pursuant to this Subscription Agreement, and (z) on the first date on which the Investor is able to sell all of its Shares issued pursuant to this
        Subscription Agreement (or shares received in exchange therefor) without restriction under Rule 144 of the Securities Act within ninety (90) days without limitation as to the amount of such securities that may be sold, any volume and manner of sale
        restrictions which may be applicable to affiliates under Rule 144 and without the requirement for Sandbridge to be in compliance with the current public information required under Rule 144(c)(i) (or Rule 144(i)(2), if applicable). The Investor
        agrees to disclose its ownership to Sandbridge upon request to assist it in making the determination described above. In no event shall the Investor be identified as a statutory underwriter in the Registration Statement unless requested by the SEC;
        provided, that if the SEC requests that the Investor be identified as a statutory underwriter in the Registration Statement, the Investor will have an opportunity to withdraw its Shares from the Registration Statement. Notwithstanding the
        foregoing, if the SEC seeks to prevent Sandbridge from including any or all of the shares proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Shares by the
        applicable stockholders or otherwise, Sandbridge shall use its best efforts to ensure that the SEC determines that (1) the offering contemplated by the Registration Statement is a bona fide secondary offering and not an offering “by or on behalf of
        the issuer” as defined in Rule 415 of the Securities Act and (2) the Investor is not a statutory underwriter. If Sandbridge is unsuccessful in the efforts described in the preceding sentence then Sandbridge shall cause such Registration Statement
        to register for resale such number of Shares which is equal to the maximum number of Shares as is permitted by the SEC. In such event, the number of Shares to be registered for each selling stockholder named in the Registration Statement shall be
        reduced pro rata among all such selling stockholders, and Sandbridge will register Investor’s remaining Shares that were not registered at the earliest date permitted by the SEC and subject to the other terms and conditions of this Section 7. For
        as long as the Registration Statement shall remain effective pursuant to this Section 7(a), Sandbridge will use commercially reasonable efforts to (1) qualify the Shares for listing on the Stock Exchange, and (2) update or amend the Registration
        Statement as necessary to include the Shares. For as long as the Investor holds the Shares, Sandbridge will use commercially reasonable efforts to file all reports, and provide all customary and reasonable cooperation, necessary to enable the
        undersigned to resell the Shares pursuant to the Registration Statement or Rule 144 of the Securities Act (when Rule 144 of the Securities Act becomes available to the Investor), as applicable. Notwithstanding anything to the contrary contained
        herein, Sandbridge may delay or postpone filing of such Registration Statement, and from time to time require the Investor not to sell under the Registration Statement or suspend the use or effectiveness of any such Registration Statement, if the
        board of directors of Sandbridge determines in good faith that either in order for the Registration Statement to not contain a material misstatement or omission, an amendment thereto would be needed, or if such filing or use could materially affect
        a bona fide business or financing transaction of Sandbridge or would require premature disclosure of information that could materially adversely affect Sandbridge (each such circumstance, a “Suspension Event”); provided, that, (I) Sandbridge
        shall not so delay filing or so suspend the use of the Registration Statement on more than two (2) occasions or for a period of more than sixty (60) consecutive days or more than a total of one hundred-twenty (120) calendar days, in each case in
        any three hundred sixty (360) day period, and (II) Sandbridge shall use commercially reasonable efforts to make such Registration Statement available for the sale by the undersigned of such securities as soon as practicable thereafter. If so
        directed by Sandbridge, the Investor will deliver to Sandbridge or, in the Investor’s sole discretion destroy, all copies of the prospectus covering the Shares in the Investor’s possession; provided, however, that this obligation to deliver or
        destroy all copies of the prospectus covering the Shares shall not apply (i) to the extent the Investor is required to

      
        
          

      

       retain a copy of such prospectus (A) in order to comply with applicable legal or regulatory requirements or (B) in accordance with a bona fide pre-existing document retention policy or (ii) to
        copies stored electronically on archival servers as a result of automatic data back-up. Sandbridge’s obligations to include the Shares issued pursuant to this Subscription Agreement (or shares issued in exchange therefor) for resale in the
        Registration Statement are contingent upon the Investor furnishing in writing to Sandbridge such information regarding the Investor, the securities of Sandbridge held by the Investor and the intended method of disposition of such Shares, which
        shall be limited to non-underwritten public offerings, as shall be reasonably requested by Sandbridge to effect the registration of such Shares, and shall execute such documents in connection with such registration as Sandbridge may reasonably
        request that are customary of a selling stockholder in similar situations; provided that the Investor shall not be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to
        transfer the Shares. Sandbridge shall provide to Investor a copy of any filing that is proposed to include disclosure relating to the Investor at least five (5) business days in advance of any disclosure thereof and shall include such revisions to
        such proposed disclosure as Investor shall reasonably request so as to result in disclosure that is compliant with applicable securities laws and regulations.

      

      

      (b) At its expense Sandbridge shall advise the Investor within two (2) business days: (i) when a Registration Statement or any post-effective amendment thereto has become
        effective; (ii) of any request by the SEC for amendments or supplements to any effective Registration Statement or the prospectus included therein or for additional information; (iii) of the issuance by the SEC of any stop order suspending the
        effectiveness of any Registration Statement or the initiation of any proceedings for such purpose; (iv) of the receipt by Sandbridge of any notification with respect to the suspension of the qualification of the Shares included therein for sale in
        any jurisdiction or the initiation or threatening of any proceeding for such purpose; and (v) subject to the provisions in this Subscription Agreement, of the occurrence of any event that requires the making of any changes in any Registration
        Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the
        light of the circumstances under which they were made) not misleading. Upon receipt of any written notice from Sandbridge (which notice shall not contain any material non-public information regarding Sandbridge or the Company) of the happening of
        any of the foregoing or of a Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact
        or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus) not misleading, the undersigned agrees that (1)
        it will immediately discontinue offers and sales of the Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until the undersigned receives copies of a supplemental or amended
        prospectus (which Sandbridge agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by Sandbridge that
        it may resume such offers and sales, and (2) it will maintain the confidentiality of any information included in such written notice delivered by Sandbridge except (A) for disclosure to the Investor’s employees, agents and professional advisers who
        need to know such information and are obligated to keep it confidential, (B) for disclosures to the extent required in order to comply with reporting obligations to its limited partners who have agreed to keep such information confidential and (C)
        as required by law or subpoena. Sandbridge shall use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable. Upon the occurrence of any
        event contemplated in clauses (i) through (v) above, except for such times as Sandbridge is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, Sandbridge shall use its commercially
        reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers
        of the Shares included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not
        misleading.

      
        
          

      

      (c) Indemnification.

      

      

      (i) Sandbridge agrees to indemnify and hold harmless, to the extent permitted by law, the Investor, its directors, and officers, trustees, partners, members, managers, shareholders, investment
        advisors, employees, and agents, and each person who controls the Investor (within the meaning of the Securities Act or the Exchange Act) and each affiliate of the Investor (within the meaning of Rule 405 under the Securities Act) from and against
        any and all losses, claims, damages, liabilities and expenses (including, without limitation, any attorneys’ fees and expenses incurred in connection with defending or investigating any such action or claim) caused by any untrue or alleged untrue
        statement of material fact contained in any Registration Statement, prospectus included in any Registration Statement (“Prospectus”) or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission
        of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to Sandbridge by or on behalf of the Investor
        expressly for use therein.

      
        
          

      

      (ii) The Investor agrees, severally and not jointly with any other person that is a party to the Other Subscription Agreements, to indemnify and hold harmless Sandbridge, its directors and officers
        and agents and each person who controls Sandbridge (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including, without limitation, reasonable attorneys’ fees) resulting from any untrue
        statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the
        statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by the Investor expressly for use therein. In no event shall the liability of the
        Investor be greater in amount than the dollar amount of the net proceeds received by such Investor upon the sale of the Shares purchased pursuant to this Subscription Agreement giving rise to such indemnification obligation.

      

      

      (iii) Any person entitled to indemnification herein shall (1) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the
        failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (2) permit such indemnifying party to assume the defense of such claim with
        counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent. An indemnifying party who
        elects not to assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of legal
        counsel to any indemnified party a conflict of interest exists between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent
        to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not
        include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation.

      

      

      (iv) The indemnification provided for under this Subscription Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any
        officer, director, employee, agent, affiliate or controlling person of such indemnified party and shall survive the transfer of the Shares purchased pursuant to this Subscription Agreement.

      
        
          

      

      (v) If the indemnification provided under this Section 7(c) from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims,
        damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages,
        liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party
        and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made
        by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The
        amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth above, any legal or other fees, charges or expenses reasonably incurred by such
        party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 7(c) from any person
        who was not guilty of such fraudulent misrepresentation. Each indemnifying party’s obligation to make a contribution pursuant to this Section 7 shall be individual, not joint and several, and in no event shall the liability of Investor hereunder
        exceed the net proceeds received by Investor upon the sale of the Shares giving rise to such indemnification obligation.

      

      

      (d)          In addition, in connection with any sale, assignment, transfer or other disposition of the Shares by the Investor pursuant to Rule 144 or pursuant to any other exemption under the
        Securities Act such that the Shares held by the Investor become freely tradable and upon compliance by the Investor with the requirements of this Subscription Agreement, if requested by the Investor, Sandbridge shall cause the transfer agent for
        the Shares (the “Transfer Agent”) to remove any restrictive legends related to the book entry account holding such Shares and make a new, unlegended entry for such book entry Shares sold or disposed of without restrictive legends within two (2)
        trading days of any such request therefor from the Investor, provided that Sandbridge and the Transfer Agent have timely received from the Investor customary representations and other documentation reasonably acceptable to Sandbridge and the
        Transfer Agent in connection therewith. Subject to receipt from the Investor by Sandbridge and the Transfer Agent of customary representations and other documentation reasonably acceptable to Sandbridge and the Transfer Agent in connection
        therewith, including, if required by the Transfer Agent, an opinion of Sandbridge’s counsel, in a form reasonably acceptable to the Transfer Agent, to the effect that the removal of such restrictive legends in such circumstances may be effected
        under the Securities Act, the Investor may request that Sandbridge remove any legend from the book entry position evidencing its Shares following the earliest of such time as such Shares (i) (x) are subject to or (y) have been or are about to be
        sold or transferred pursuant to an effective registration statement, (ii) have been or are about to be sold pursuant to Rule 144, or (iii) are eligible for resale under Rule 144(b)(1) or any successor provision without the requirement for
        Sandbridge to be in compliance with the current public information requirement under Rule 144 and without volume or manner-of-sale restrictions applicable to the sale or transfer of such Shares. If restrictive legends are no longer required for
        such Shares pursuant to the foregoing, Sandbridge shall, in accordance with the provisions of this Section 7(f) and within two (2) trading days of any request therefor from the Investor accompanied by such customary and reasonably acceptable
        representations and other documentation referred to above establishing that restrictive legends are no longer required, deliver to the Transfer Agent instructions that the Transfer Agent shall make a new, unlegended entry for such book entry
        Shares. Sandbridge shall be responsible for the fees of its Transfer Agent and all DTC fees associated with such issuance.

      
        
          

      

      8. Termination. This Subscription Agreement shall terminate and be void and of no further force or effect, and all rights and obligations of the parties hereunder shall terminate without
        any further liability on the part of any party in respect thereof, upon the earliest to occur of (a) such date and time as the Transaction Agreement is terminated in accordance with its terms, (b) upon the mutual written agreement of each of the
        parties hereto to terminate this Subscription Agreement, (c) July 31, 2021, if the Closing has not occurred by such date, and (d) if any of the conditions to Closing set forth in Section 3 of this Subscription Agreement are not satisfied or waived,
        or are not capable of being satisfied, on or prior to the Closing and, as a result thereof, the transactions contemplated by this Subscription Agreement will not be and are not consummated at the Closing (the termination events described in clauses
        (a)-(d) above, collectively, the “Termination Events”); provided that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law
        or in equity to recover losses, liabilities or damages arising from any such willful breach. Sandbridge shall notify the Investor of the termination of the Transaction Agreement promptly after the termination of such agreement. Upon the occurrence
        of any Termination Event, this Subscription Agreement shall be void and of no further force or effect and any monies paid by the Investor to Sandbridge in connection herewith shall promptly (and in any event within one business day) following the
        Termination Event be returned to the Investor without any deduction for or on account of any tax, withholding, charges or set-off.

      

      

      9. Trust Account Waiver. The Investor acknowledges that Sandbridge is a blank check company with the powers and privileges to effect a merger, asset acquisition, reorganization or similar
        business combination involving Sandbridge and one or more businesses or assets. The Investor further acknowledges that, as described in Sandbridge’s prospectus relating to its initial public offering dated September 14, 2020 (the “IPO Prospectus”)

        available at www.sec.gov, substantially all of Sandbridge’s assets consist of the cash proceeds of Sandbridge’s initial public offering and private placement of its securities, and substantially all of those proceeds have been deposited in a trust
        account (the “Trust Account”) for the benefit of Sandbridge, its public stockholders and the underwriters of Sandbridge’s initial public offering. Except with respect to interest earned on the funds held in the Trust Account that may be
        released to Sandbridge to pay its tax obligations, if any, the cash in the Trust Account may be disbursed only for the purposes set forth in the IPO Prospectus. For and in consideration of Sandbridge entering into this Subscription Agreement, the
        receipt and sufficiency of which are hereby acknowledged, the Investor hereby irrevocably waives any and all right, title and interest, or any claim of any kind it has or may have in the future, in or to any monies held in the Trust Account, and
        agrees not to seek recourse against the Trust Account as a result of, or arising out of, this Subscription Agreement; provided, however, that nothing in this Section 9 shall be deemed to limit the Investor’s right, title, interest or claim to any
        monies held in the Trust Account by virtue of its record or beneficial ownership of shares of Class A Stock currently outstanding on the date hereof, pursuant to a validly exercised redemption right with respect to any such shares of Class A Stock,
        except to the extent that the Investor has otherwise agreed with Sandbridge to not exercise such redemption right.

      
        
          

      

      10. Miscellaneous.

      

      

      a. Neither this Subscription Agreement nor any rights that may accrue to the Investor hereunder (other than the Shares acquired hereunder, if any) may be transferred or assigned. Notwithstanding
        the foregoing, Investor may assign its rights and obligations under this Subscription Agreement to one or more of its affiliates (including other investment funds or accounts managed or advised by the investment manager who acts on behalf of
        Investor) or, with the Sandbridge’s prior written consent, to another person, provided that no such assignment shall relieve Investor of its obligations hereunder if any such assignee fails to perform such obligations.

      

      

      b. Sandbridge may request from the Investor such additional information as Sandbridge may deem necessary to register the resale of the Shares and evaluate the eligibility of the Investor to acquire
        the Shares, and the Investor shall provide such information as may reasonably be requested to the extent readily available and to the extent consistent with its internal policies and procedures; provided that Sandbridge agrees to keep any such
        information provided by Subscriber confidential.

      

      

      c. The Investor acknowledges that Sandbridge will rely on the acknowledgments, understandings, agreements, representations and warranties of the Investor contained in this Subscription Agreement.
        Prior to the Closing, the Investor agrees to promptly notify Sandbridge and the Placement Agents if any of the acknowledgments, understandings, agreements, representations and warranties set forth in Section 6 above are no longer accurate. The
        Investor acknowledges and agrees that each purchase by the Investor of Shares from Sandbridge will constitute a reaffirmation of the acknowledgments, understandings, agreements, representations and warranties herein (as modified by any such notice)
        by the Investor as of the time of such purchase.

      

      

      d. Sandbridge acknowledges and agrees that each of the Placement Agents is entitled to rely on the representations and warranties of Sandbridge contained in this Subscription Agreement. The
        Investor acknowledges and agrees that each of the Placement Agents is entitled to rely on the representations and warranties of the Investor contained in this Subscription Agreement.

      

      

      e. Each of the Investor and Sandbridge are entitled to rely upon this Subscription Agreement; provided, however, that the foregoing clause of this Section 10(e) shall not give the Placement Agents
        any rights other than those expressly set forth herein and, without limiting the generality of the foregoing.

      

      

      f. All of the agreements, representations and warranties made by each party hereto in this Subscription Agreement shall survive the Closing.

      

      

      g. This Subscription Agreement may not be amended, modified, waived or terminated (other than pursuant to the terms of Section 8 above) except by an instrument in writing, signed by each of the
        parties hereto. No failure or delay of either party in exercising any right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to
        enforce such right or power, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the parties hereunder are cumulative and are not exclusive of any rights
        or remedies that they would otherwise have hereunder.

      
        
          

      

      h. This Subscription Agreement (including the schedule hereto) constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties, both
        written and oral, among the parties, with respect to the subject matter hereof. Except as otherwise provided herein, this Subscription Agreement shall not confer any rights or remedies upon any person other than the parties hereto, and their
        respective successor and assigns, and the parties hereto acknowledge that such persons so referenced are third-party beneficiaries of this Subscription Agreement for the purposes of, and to the extent of, the rights granted to them, if any,
        pursuant to such provisions.

      

      

      i. Except as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to the benefit of the parties hereto and their heirs, executors, administrators, successors,
        legal representatives, and permitted assigns, and the agreements, representations, warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such heirs, executors, administrators, successors,
        legal representatives and permitted assigns.

      

      

      j. If any provision of this Subscription Agreement shall be adjudicated by a court of competent jurisdiction to be invalid, illegal or unenforceable, the validity, legality or enforceability of the
        remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect.

      

      

      k. This Subscription Agreement may be executed by wet-ink signature or electronically, in one or more counterparts and by different parties in separate counterparts, and delivered by facsimile or
        electronic mail or in .pdf, with the same effect as if all parties hereto had manually signed the same document. All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement.

      

      

      l. The parties hereto acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Subscription Agreement were not performed in accordance with their
        specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Subscription Agreement, without posting a bond or undertaking and without proof of
        damages, to enforce specifically the terms and provisions of this Subscription Agreement, this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise.

      

      

      m. Any notice or communication required or permitted hereunder to be given to the Investor or Sandbridge shall be in writing and either delivered personally, emailed or sent by overnight mail via a
        reputable overnight carrier, or sent by certified or registered mail, postage prepaid, (1) in the case of the Investor, to such address(es) or email address(es) set forth on the signature page hereto, and shall be deemed to be given and received
        (i) when so delivered personally, (ii) when sent, with no mail undeliverable or other rejection or out-of-office notice, if sent by email, or (iii) three (3) business days after the date of mailing to the address below or to such other address or
        addresses as the Investor may hereafter designate by notice to Sandbridge and (2) in the case of Sandbridge, to its address set forth on the cover of the Registration Statement/Proxy Statement or to ksuslow@sandbridge.com.

      
        
          

      

      n. The Investor hereby acknowledges and agrees that it will not, and will cause each person acting at the Investor’s direction or pursuant to any understanding with the Investor to not, directly or
        indirectly offer, sell, pledge, contract to sell or sell any option to purchase, or engage in hedging activities or execute any “short sales” as defined in Rule 200 of Regulation SHO under the Exchange Act in respect of, Sandbridge’s Class A common
        stock until the consummation of the transactions contemplated hereby (or such earlier termination of this Subscription Agreement in accordance with its terms). For the avoidance of doubt, nothing contained herein shall prohibit Investor from
        engaging in (i) any purchase of securities by the Investor, its controlled affiliates or any person or entity acting on behalf of the Investor or any of its controlled affiliates in an open market transaction after the execution of this
        Subscription Agreement, or (ii) any sale (including the exercise of any redemption right) of securities of Sandbridge (A) held by the Investor, its controlled affiliates or any person or entity acting on behalf of the Investor or any of its
        controlled affiliates prior to the execution of this Subscription Agreement or (B) purchased by the Investor, its controlled affiliates or any person or entity acting on behalf of the Investor or any of its controlled affiliates in an open market
        transaction after the execution of this Subscription Agreement. Notwithstanding the foregoing, (i) nothing herein shall prohibit other entities under common management with Investor that have no knowledge of this Subscription Agreement or of
        Investor’s participation in the Transaction (including the Investor’s controlled affiliates and/or affiliates) from entering into any “short sales” as defined in Rule 200 of Regulation SHO under the Exchange Act and (ii) in the case of an Investor
        that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Investor’s assets and the portfolio managers have no knowledge of the investment decisions made by the portfolio managers managing other
        portions of such Investor’s assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Shares covered by this Subscription
        Agreement.

      

      

      o. Investor shall pay all of its own expenses in connection with this Subscription Agreement and the transactions contemplated herein.

      

      

      p. THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURT OF CHANCERY OF THE STATE OF DELAWARE (OR, TO THE EXTENT SUCH COURT DOES NOT HAVE SUBJECT MATTER JURISDICTION, THE

        to the Investor pursuant to, arising out of or relating to this Subscription Agreement, the negotiation hereof or thereof or its subject matter, or the transactions contemplated hereby or thereby, including, without limitation, with respect to any
        action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Shares or with respect to any claim (whether in tort, contract or otherwise) for breach of this Subscription Agreement or in respect
        of any written or oral representations made or alleged to be made in connection herewith, as expressly provided herein, or for any actual or alleged inaccuracies, misstatements or omissions with respect to any information or materials of any kind
        furnished by Sandbridge, the Company, the Placement Agents or any Non-Party Affiliate concerning Sandbridge, the Company, the Placement Agents, any of their controlled affiliates, this Subscription Agreement or the transactions contemplated hereby.
        For purposes of this Subscription Agreement, “Non-Party Affiliates” means each former, current or future officer, director, employee, partner, member, manager, direct or indirect equityholder or affiliate of Sandbridge, the Company, any Placement
        Agent or any of Sandbridge’s, the Company’s or any Placement Agent’s controlled affiliates or any family member of the foregoing.

        releases or file with the SEC a Current Report on Form 8-K (collectively, the “Disclosure Document”) disclosing all material terms of the transactions contemplated hereby and by the Other Subscription Agreements, the Transaction and any
        other material, nonpublic information that Sandbridge, the Company or any of its officers, directors, employees or agents (including the Placement Agents) has provided to the Investor at any time prior to the filing of the Disclosure Document. From
        and after the issuance of the Disclosure Document, the Investor shall not be in possession of any material, non-public information received from Sandbridge or any of its officers, directors, employees or agents (including the Placement Agents), and
        the Investor  shall no longer be subject to any confidentiality or similar obligations under any current agreement, whether written or oral, with Sandbridge or any of its affiliates or agents relating to the transactions contemplated by this
        Subscription Agreement. Except with the express written consent of Investor and unless prior thereto the Investor shall have executed a written agreement regarding the confidentiality and use of such information, Sandbridge shall not, and shall
        cause its officers, directors, employees and agents, not to, provide the Investor with any material, non-public information regarding Sandbridge or the Transaction from and after the filing of the Disclosure Document. Sandbridge acknowledges that
        the Investor is entitled to rely on provisions of this Section 12 in effecting transactions in securities of Sandbridge. Notwithstanding anything in this Subscription Agreement to the contrary, Sandbridge (i) shall not, without the prior written

      13. Legal Opinions. If a transfer agent requires a legal opinion stating that it is permissible to remove the restrictive legend from the Shares pursuant to Rule 144 of the Securities Act
        in order to effect a proposed transfer of Shares by the Investor that is otherwise permissible under Rule 144 of the Securities Act, then at the Investor’s request, Sandbridge shall promptly, at its sole cost and expense, cause its legal counsel to
        issue such opinion to the transfer agent, subject to receipt by Sandbridge’s counsel and transfer of any reasonable and customary documentation they may require from or on behalf of the Investor.

                or her spouse.  (See Annex A to this Investor Questionnaire for the definition of and method for calculating the value of “Investments”);

            
	 	 
	☐ 

            	
              The Investor is an entity, acting for its own account or the accounts of other “qualified purchasers,” that in the aggregate owns and invests on
                a discretionary basis not less than $25,000,000 in “Investments.”  (See Annex A to this Investor Questionnaire for the definition of and method for calculating the value of “Investments”);

            
	 	 
	☐ 

            	
              The Investor is a “family company” that owns not less than $5,000,000 in “Investments.” (See Annex A to this Investor Questionnaire for the
                definition of and method for calculating the value of “Investments.”)  A “family company” means any company (including a trust, partnership, limited liability company or corporation) that is owned directly or indirectly by or for (a)(i) two

                make decisions with respect to the trust) and each grantor (or other person who has contributed assets to the trust) of which are “qualified purchasers”.

      Annex A to Investor Questionnaire

      

      

      INVESTMENTS

      

      

      For determining whether the Investor is a “qualified purchaser,” the term “Investments” means:

      

      

      	1.	
              Securities (as defined by Section 2(a)(1) of the Securities Act), other than securities of an issuer that controls, is controlled by, or is under common control with, the Investor that owns such securities, unless the issuer of such
                securities is a “public company,” a “financial company” or has more than $50,000,000 in equity, as reflected on such company’s financial statements which present such equity information as of a date within 16 months preceding the date on
                which the Investor acquires an Interest.  The term “public company” includes all companies that file reports pursuant to Section 13 or 15(d) of the Exchange Act or have a class of securities that are listed on a Designated Offshore
                Securities Market, as defined  by Regulation S of the Securities Act.  The term “financial company” includes a commodity pool or an “investment company” (whether U.S. or offshore) or a company required to register as such under the
                Investment Company Act but for the exclusions or exemptions provided by Sections 3(c)(1) through 3(c)(9) of the Investment Company Act;

            

      

      

      	2.	
              Real estate held for investment purposes so long as it is not used by the prospective qualified purchaser or a close relative (generally, a sibling, spouse, former spouse, direct ancestor or descendent or a spouse of such an ancestor or
                descendent) for personal or business purposes.  However, real estate owned by a prospective qualified purchaser who is primarily in the real estate business is includable as an “investment” even if it is held by the owner;

            

      

      

      	3.	
              “Commodity Interests” or “Physical Commodity” held for investment purposes by the Investor.  “Commodity Interests” means commodity futures contracts, options on commodity futures contracts, and options on physical commodities traded on
                or subject to the rules of (a) any contract market designated for trading such transactions under the Commodity Exchange Act, and the regulations issued thereunder and the rules thereunder, or (b) any board of trade or exchange outside the
                United States, as contemplated in Part 30 of the rules under the Commodity Exchange Act.  “Physical Commodity” means any physical commodity with respect to which a “Commodity Interest” is traded on a market specified in the definition of
                Commodity Interests above;

            

      

      

      	4.	
              To the extent not securities, “financial contracts” entered into for investment purposes or in connection with investments.  “Financial contracts” means any arrangement that (a) takes the form of an individually negotiated contract,
                agreement, or option to buy, sell, lend, swap, or repurchase, or other similar individually negotiated transaction commonly entered into by participants in the financial markets; (b) is in respect of securities, commodities, currencies,
                interest or other rates, other measures of value, or any other financial or economic interest similar in purpose or function to any of the foregoing; and (c) is entered into in response to a request from a counterparty for a quotation, or
                is otherwise entered into and structured to accommodate the objectives of the counterparty to such arrangement;

            

      

      

      	5.	
              In the case of an Investor that is a commodity pool operator or an investment company excepted from registration by Section 3(c)(1) or 3(c)(7) of the Investment Company Act, any amounts payable to such Investor pursuant to a firm
                agreement or similar binding commitment pursuant to which a person has agreed to acquire an interest in, or make Capital Contributions to, the Investor upon the demand of the Investor; and

            

      

      

      	6.	
              Cash and cash equivalents (including foreign currencies) held for investment purposes.  “Cash and cash equivalents” include bank deposits, certificates of deposits, bankers acceptances and similar bank instruments held for investment
                purposes and the net cash surrender value of an insurance policy.

            

      

      

      “Investments” do not include other assets which do not reflect experience in the financial markets, such as jewelry, art work, antiques and other collectibles.

      

      

      For purposes of determining the amount of “Investments” owned by a company, “Investments” of a parent company and its majority-owned subsidiaries may be aggregated to meet the minimum “investment” amount requirements,
        regardless of which company is the prospective qualified purchaser.

      
        
          

      

      For purposes of determining the amount of “Investments” owned by an individual, there may be included any “investment” held jointly or as community property with such person’s spouse.  In determining whether spouses
        who are making a joint investment in the Partnership are qualified purchasers, there may be included in the amount of each spouse’s “Investments” any “Investments” owned by the other spouse (whether or not such “investments” are held jointly).

      

      

      In determining whether an individual is a qualified purchaser, there may be included in the amount of such person’s “Investments” any “Investments” held in an individual retirement account or similar account the
        investments of which are directed by and held for the benefit of such person.

      

      

      VALUATION OF INVESTMENTS

      

      

      In determining the value of “Investments” in order to ascertain qualified purchaser status, the aggregate amount of “Investments” owned and invested on a discretionary basis by such person shall be their fair market
        value on the most recent practicable date or their cost provided that the same method must be used for all “Investments.” However,

      

      

      	1.	
              in the case of “Commodity Interests,” the amount of “Investments” is the value of the initial margin or option premium deposited in connection with such “Commodity Interests,” and
