Re:Sponsor
Agreement

 

Ladies and Gentlemen:

 

This
letter (this “Sponsor Agreement”) is being delivered to you in connection with that certain Agreement and Plan
of Merger (the “Merger Agreement”), dated as of the date hereof, by and among Churchill Capital Corp IV, a
Delaware corporation (“SPAC”), Atieva, Inc., d/b/a Lucid Motors, an exempted limited liability company organized
under the laws of the Cayman Islands (the “Company”), and Air Merger Sub,
Inc., a Delaware corporation and direct, wholly owned subsidiary of SPAC, and hereby amends and restates
in its entirety that certain letter, dated July 29, 2020, from Churchill Sponsor IV LLC (the “Sponsor”) and
each of the undersigned individuals, each of whom is a member of SPAC’s board of directors and/or management team (each,
an “Insider” and collectively, the “Insiders”) to SPAC (the “Prior Letter Agreement”).
Certain capitalized terms used herein are defined in paragraph 10 hereof. Capitalized terms used but not otherwise defined herein
shall have the respective meanings ascribed to such terms in the Merger Agreement.

 

In
order to induce the Company and SPAC to enter into the Merger Agreement and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, Sponsor and each of the Insiders, hereby severally (and not jointly and severally)
agrees with SPAC and, at all times prior to any valid termination of the Merger Agreement, the Company as follows:

 

1.             The
Sponsor and each Insider hereby unconditionally and irrevocably agrees: (i) that at any duly called meeting of the stockholders
of SPAC (or any adjournment or postponement thereof), and in any action by written consent of the stockholders of SPAC requested
by SPAC’s board of directors or undertaken as contemplated by the Transactions, the Sponsor and each such Insider shall,
if a meeting is held, appear at the meeting, in person or by proxy, or otherwise cause all of its, his or her shares of Capital
Stock to be counted as present thereat for purposes of establishing a quorum, and it shall vote or consent (or cause to be voted
or consented), in person or by proxy, all of its, his or her shares of Capital Stock (a) in favor of the adoption of the Merger
Agreement and approval of the Transactions and all other SPAC Stockholder Matters (and any actions required in furtherance thereof),
(b) against any action, proposal, transaction or agreement that would reasonably be expected to result in a breach of any representation,
warranty, covenant, obligation or agreement of SPAC contained in the Merger Agreement, (c) in favor of any other proposals set
forth in SPAC’s proxy statement to be filed by SPAC with the SEC relating to the Transactions (including any proxy supplements
thereto, the “Proxy Statement”), (d) for any proposal to adjourn or postpone the applicable stockholder meeting
to a later date if (and only if) (1) there are not sufficient votes for approval of the Merger Agreement and any other proposals
related thereto as set forth in the Proxy Statement on the dates on which such meetings are held or (2) the closing condition
in Section 10.03(c) of the Merger Agreement has not been satisfied, and (e) against the following actions or proposals: (1) any
Business Combination Proposal or any proposal in opposition to approval of the Merger Agreement or in competition with or inconsistent
with the Merger Agreement; and (2) (A) any change in the present capitalization of SPAC or any amendment of the SPAC’s Charter
(as defined below), except to the extent expressly contemplated by the Merger Agreement, (B) any liquidation, dissolution or other
change in SPAC’s corporate structure or business, (C) any action, proposal, transaction or agreement that would result in
a breach in any material respect of any covenant, representation or warranty or other obligation or agreement of the Sponsor or
such Insider under this Sponsor Agreement, or (D) any other action or proposal involving SPAC or any of its subsidiaries that
is intended, or would reasonably be expected, to prevent, impede, interfere with, delay, postpone or adversely affect the Transactions
and (ii) not to redeem, elect to redeem or tender or submit any shares of Common Stock owned by it, him or her for redemption
in connection with such stockholder approval or proposed Business Combination, or in connection with any vote to amend SPAC’s
Charter. Prior to any valid termination of the Merger Agreement, (x) the Sponsor and each Insider shall take, or cause to be taken,
all actions and to do, or cause to be done, all things reasonably necessary under applicable Laws to consummate the Merger and
the other transactions contemplated by the Merger Agreement and on the terms and subject to the conditions set forth therein,
and (y) the Sponsor and each Insider shall be bound by and comply with Sections 9.03 (Exclusivity) and 9.05 (Confidentiality;
Publicity) of the Merger Agreement (and any relevant definitions contained in any such Sections) as if such Person were a signatory
to the Merger Agreement with respect to such provisions. If SPAC seeks to consummate a proposed Business Combination by engaging
in a tender offer, the Sponsor and each Insider agrees that it, he or she will not sell or tender any shares of Capital Stock
owned by it, him or her in connection therewith. The obligations of the Sponsor and the Insiders specified in this paragraph 1
shall apply whether or not the Merger, any of the Transactions or any action described above is recommend by SPAC’s board
of directors.

 

     

     

    

 

2.             The
Sponsor and each Insider hereby agrees that in the event that SPAC fails to consummate a Business
Combination by August 3, 2022 (or November 3, 2022 if SPAC has executed a letter of intent, agreement in principle or definitive
agreement for an initial business combination before August 3, 2022),
or such later period approved by SPAC’s stockholders in accordance with SPAC’s amended and restated certificate of
incorporation (the “Charter”), the Sponsor and each Insider shall take all reasonable steps to cause SPAC to
(i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than 10 Business
Days thereafter, subject to lawfully available funds therefor, redeem 100% of the Common Stock sold as part of the Units in the
Public Offering (the “Offering Shares”), at a per-share price, payable in cash, equal to the aggregate amount
then on deposit in the Trust Account, including interest (net of amounts withdrawn to fund SPAC’s working capital requirements,
subject to an annual limit of $1,000,000, and/or to pay SPAC’s taxes (“Permitted Withdrawals”)) and less
up to $100,000 of interest to pay dissolution expenses)), divided by the number of then outstanding Offering Shares, which redemption
will completely extinguish all Public Stockholders’ rights as stockholders (including the right to receive further liquidating
distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject
to the approval of SPAC’s remaining stockholders and SPAC’s board of directors, dissolve and liquidate, subject in
each case to SPAC’s obligations under Delaware law to provide for claims of creditors and other requirements of applicable
law. The Sponsor and each Insider agree to not propose any amendment to the Charter that would modify the substance or timing
of SPAC’s obligation to redeem 100% of the Offering Shares if SPAC does not complete a Business Combination within the required
time period set forth in the Charter or with respect to any other material provisions relating to stockholders’ rights or
pre-initial business combination activity, unless SPAC provides its Public Stockholders with the opportunity to redeem their Offering
Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit
in the Trust Account, including interest (net of Permitted Withdrawals), divided by the number of then outstanding Offering Shares.

  

    	 	2	 

     

    

 

The
Sponsor and each Insider acknowledges that it, he or she has no right, title, interest or claim of any kind in or to any monies
held in the Trust Account or any other asset of SPAC as a result of any liquidation of SPAC with respect to the Founder Shares
held by it, him or her. The Sponsor and each Insider hereby further waive, with respect to any shares of Common Stock held by
it, him or her, if any, any redemption rights it, he or she may have in connection with the consummation of a Business Combination,
including, without limitation, any such rights available in the context of a stockholder vote to approve such Business Combination
or in the context of a tender offer made by SPAC to purchase shares of Common Stock (although the Sponsor, the Insiders and their
respective Affiliates shall be entitled to redemption and liquidation rights with respect to any Offering Shares it or they hold
if SPAC fails to consummate a Business Combination within the time period set forth in the Charter or in connection with a stockholder
vote to approve an amendment to the Charter to modify the substance or timing of the Company’s obligation to redeem 100%
of the Offering Shares if the Company does not complete a Business Combination within the time period set forth in the Charter
or with respect to any other material provisions relating to stockholders' rights or pre-initial business combination activity).

 

3.             Without
limiting their obligations under paragraph 6 below or pursuant to the Investor Rights Agreement, during the period commencing
on the date hereof and ending on the earlier of (a) the valid termination of the Merger Agreement or (b) the Closing,
the Sponsor and each Insider shall not, without the prior written consent of the Company, Transfer any Units, shares of Capital
Stock, warrants (each, a “Warrant”) to purchase shares of Common Stock or any securities convertible into,
or exercisable, or exchangeable for, shares of Common Stock owned by it, him or her. In the event that (i) any shares of Capital
Stock, Warrants or other equity securities of SPAC are issued to the Sponsor or any Insider after the date hereof pursuant to
any stock dividend, stock split, recapitalization, reclassification, combination or exchange of shares of Capital Stock of, on
or affecting the shares of Capital Stock owned by the Sponsor or any Insider or otherwise, (ii) the Sponsor or any Insider purchases
or otherwise acquires beneficial ownership of any shares of Capital Stock, Warrants or other equity securities of SPAC after the
date hereof or (iii) the Sponsor or any Insider acquires the right to vote or share in the voting of any shares of Capital Stock,
Warrants or other equity securities of SPAC after the date hereof (such shares of Capital Stock, Warrants or other equity securities
of SPAC described in clauses (i), (ii) and (iii), the “New Shares”), then such New Shares acquired or purchased
by the Sponsor or any Insider shall be subject to the terms of this paragraph 3 and paragraph 1 above to the same extent as if
they constituted the Capital Stock or Warrants owned by the Sponsor or any Insider as of the date hereof.

 

    	 	3	 

     

    

 

4.             In
the event of the liquidation of the Trust Account, the Sponsor (which for purposes of clarification shall
not extend to any other shareholders, members or managers of the Sponsor or any other Insider) agrees to indemnify and hold harmless
SPAC against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal
or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened,
or any claim whatsoever) to which SPAC may become subject as a result of any claim by (i) any third party for services rendered
or products sold to SPAC or (ii) any prospective target business with which SPAC has entered into a letter of intent, confidentiality
or other similar agreement for a Business Combination (a “Target”); provided, however, that such
indemnification of SPAC by the Sponsor (x) shall apply only to the extent necessary to ensure that such claims by a third party
or a Target do not reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00
per Offering Share or (ii) the actual amount per Offering Share held in the Trust Account
as of the date of the liquidation of the Trust Account, if less than $10.00 per Offering Share is then held in the Trust Account
due to reductions in the value of the trust assets less Permitted Withdrawals, (y) shall not apply to any claims by a third party
(including a Target) that executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such
waiver is enforceable) and (z) shall not apply to any claims under SPAC’s indemnity
of Citigroup Global Markets Inc. (the “Representative”) against certain liabilities, including liabilities
under the Securities Act of 1933, as amended. The Sponsor shall have the right to defend against any such claim with counsel of
its choice reasonably satisfactory to SPAC if, within 15 days following written receipt of notice of the claim to the Sponsor,
the Sponsor notifies SPAC in writing that it shall undertake such defense. For the avoidance of doubt, none of SPAC’s
officers or directors will indemnify SPAC for claims by third parties, including, without limitation,
claims by vendors and prospective target businesses.

 

5.             The
Sponsor and each Insider hereby agrees and acknowledges that: (i) the Representative, SPAC
and, prior to any valid termination of the Merger Agreement, the Company would be irreparably injured in the event of a breach
by such Sponsor or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 6(a), 6(b), 6(c), 6(d), 6(e), 8 and
12, as applicable, of this Sponsor Agreement (with respect to the Representative, only such provisions as were contained in the
Prior Letter Agreement), (ii) monetary damages may not be an adequate remedy for such breach
and (iii) the non-breaching party shall be entitled to injunctive relief, in addition to any
other remedy that such party may have in law or in equity, in the event of such breach.

 

    	 	4	 

     

    

 

6.            (a)In
the event that the Closing does not occur for any reason (including, without limitation, as a result of the valid termination
of the Merger Agreement), the Sponsor and each Insider agrees that it, he or she shall not Transfer (i) any Founder Shares (or
shares of Common Stock issuable upon conversion thereof) until the earlier of (A) one year after the completion of SPAC’s
initial Business Combination or (B) subsequent to the Business Combination, (x) if the closing price
of the Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations
and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after SPAC’s
initial Business Combination or (y) the date on which SPAC completes a liquidation, merger, capital
stock exchange, reorganization or other similar transaction that results in all of SPAC’s stockholders
having the right to exchange their shares of Common Stock for cash, securities or other property (the “Standalone Founder
Shares Lock-Up Period”) and (ii) any Private Placement Warrants (or shares of Common Stock issued or issuable
upon the exercise of the Private Placement Warrants) until 30 days after the completion of a Business Combination (the “Standalone
Private Placement Warrants Lock-up Period”).

 

(b)              
In the event that the Closing does occur, the Sponsor and each Insider agrees that it, he or she shall not Transfer (A)
any Founder Shares or any other Capital Stock of SPAC owned by such Person as of the Closing Date (after giving effect to the
consummation of the Transactions) or the Private Placement Warrants, or (B) any shares of Common Stock issued or issuable upon
the exercise of such Private Placement Warrants (clauses (A) and (B), collectively, the “Locked-Up SPAC Securities”)
until the eighteen month anniversary of the Closing Date (such period, the “Merger Agreement
Lock-Up Period” and, together with the Standalone Founder Shares Lock-Up Period and the Standalone Private Placement
Warrants Lock-Up Period, the “Lock-Up Periods”).

Stock) that were eligible to vest pursuant to paragraph 6(d)(i)(2) or 6(d)(ii)(2), as the case may be, if such Sale occurs on

    	 	8	 

     

    

 

(5)              
For purposes of this paragraph 6(d)(iii), “Sale” means (A) a purchase, sale, exchange, business combination
or other transaction (including a merger or consolidation of SPAC with or into any other corporation or other entity) in which
the equity securities of SPAC, its successor or the surviving entity of such business combination or other transaction are not
registered under the Securities Exchange Act or 1934, as amended (the “Exchange Act”) or listed or quoted for
trading on a national securities exchange or (B) a sale, lease, exchange or other transfer in one transaction or a series of related
transactions of all or substantially all of SPAC’s assets to a third party that is not an Affiliate of the Sponsor (or a
group of third parties that are not Affiliates of the Sponsor). For avoidance of doubt, following a transaction or business combination
that is not a “Sale” hereunder, including a transaction or business combination in which the equity securities of
the surviving entity of such business combination or other transaction are registered under the Exchange Act and listed or quoted
for trading on a national securities exchange, the equitable adjustment provisions of paragraph 21 shall apply, including, without
limitation, to performance vesting criteria.

 

(6)              
Holders of Founder Shares or shares of Common Stock subject to the vesting provisions of this paragraph 6(d) shall be entitled
to vote such Founder Shares or shares of Common Stock and receive dividends and other distributions with respect to such Founder
Shares or shares of Common Stock prior to vesting; provided, that dividends and other distributions with respect to Founder
Shares or shares of Common Stock that are subject to vesting pursuant to paragraph 6(d)(i) or 6(d)(ii) shall be set aside by SPAC
and shall only be paid to such holders upon the vesting of such Founder Shares or shares of Common Stock issuable upon the conversion
of the Founder Shares or exercise of Private Placement Warrants (if at all); for the avoidance of doubt, (i) such dividends and
other distributions shall be paid only on the portion of the unvested Founder Shares or shares of Common Stock that vest and (ii)
if any dividends or other distributions with respect to Founder Shares or shares of Common Stock that are subject to vesting pursuant
to paragraph 6(d)(i) or 6(d)(ii) are set aside and such Founder Shares or shares of Common Stock are subsequently forfeited, such
set aside dividends or distributions shall become the property of SPAC.

 

(iv)          Forfeiture.

 

(1)              
Founder Shares or shares of Common Stock that are forfeited pursuant to paragraph 6(d)(i), 6(d)(iii) or 6(e) shall be transferred
by Sponsor to SPAC, without any consideration for such Transfer, and cancelled.

 

(2)              
Private Placement Warrants or shares of Common Stock that are forfeited pursuant to paragraph 6(d)(ii), 6(d)(iii) or 6(e)
shall be transferred by Sponsor to SPAC, without any consideration for such Transfer, and cancelled.

 

(v)           Stock
Price Level. For purposes of this paragraph 6(d), the applicable “Stock Price Level” will be considered
achieved only when the volume weighted average price per share of Common Stock on the New York Stock Exchange, or such other securities
exchange where the Common Stock is listed or quoted, equals or exceeds the applicable threshold for any 40 trading days during
a 60 consecutive trading day period. The Stock Price Levels (and the share price levels in a Sale in paragraph 6(d)(iii)) will
be equitably adjusted on account of any stock split, reverse stock split or similar equity restructuring transaction.

 

    	 	9	 

     

    

 

(vi)          Waiver
of Conversion Ratio Adjustment.

 

(1)              
(A) Section 4.3(b)(i) of the Charter provides that each share of Class B Common Stock shall automatically convert into
one share of Common Stock (the “Initial Conversion Ratio”) at the time of the Business Combination, and (B)
Section 4.3(b)(ii) of the Charter provides that the Initial Conversion Ratio shall be adjusted (the “Adjustment”)
in the event that additional shares of Common Stock are issued in excess of the amounts offered in SPAC’s initial public
offering of securities such that the Sponsor and the Insiders shall continue to own 20% of the issued and outstanding shares of
Capital Stock after giving effect to such issuance.

 

(2)              
As of and conditioned upon the Closing, the Sponsor and each Insider hereby irrevocably relinquishes and waives any and
all rights the Sponsor and each Insider has or will have under Section 4.3(b)(ii) of the Charter to receive shares of Common Stock
in excess of the number issuable at the Initial Conversion Ratio upon conversion the existing Class B Common Stock held by him,
her or it, as applicable, in connection with the Closing as a result of any Adjustment, and, as a result, the shares of Class
B Common Stock shall convert into shares of Common Stock (or such equivalent security) at Closing on a one-for-one basis.

 

(e)              
Transaction Expenses and Liabilities. Sponsor hereby agrees that to the extent SPAC Expenses as of immediately prior
to the Closing (including any such amounts that become payable as a result of the Closing) exceeds $128,000,000 (the “Expense
Cap”), then Sponsor shall, as of and conditioned upon the Closing, at its election, either (x) pay any such amount in
excess of the Expense Cap to SPAC in cash, by wire transfer of immediately available funds to the account designated by SPAC or
(y) forfeit in accordance with paragraph 6(d)(iv) such number of Founder Shares or Private Placement Warrants (valued at $10.00
per Founder Share and $1.00 per Private Placement Warrant) held by Sponsor that, in the aggregate, have a value equal to such
amount in excess of the Expense Cap. If Sponsor shall elect to forfeit Founder Shares or Private Placement Warrants, such forfeited
Founder Shares or Private Placement Warrants shall first reduce the number of vested Founder Shares or vested Private Placement
Warrants, as applicable, and, only after all vested Founder Shares or vested Private Placement Warrants, as applicable, have been
forfeited, shall reduce the number of unvested Founder Shares or unvested Private Placement Warrants, with such reductions applied
pro rata to the tranches of Founder Shares or Private Placement Warrants that vest at each Stock Price Level. If Sponsor shall
elect to forfeit Founder Shares or Private Placement Warrants and the number of Founder Shares or Private Placement Warrants available
for forfeiture pursuant to this paragraph 6(e) shall be insufficient to satisfy Sponsor’s obligations under this paragraph
6(e), then Sponsor shall, as of and conditioned upon the Closing, satisfy any such additional obligations in cash. In the event
that the amount of any contingent liabilities of SPAC as of immediately prior to the Closing are unknown, Sponsor and the Company
will negotiate in good faith in order to reach agreement on the amount thereof and, in the event that Sponsor and the Company
are unable to reach agreement prior to the Closing, such disagreement shall not delay the Closing and the SPAC Expenses shall
be recalculated each time such contingent liabilities crystallize and if such recalculation results in SPAC Expenses exceeding
the Expense Cap or an increase in the amount of such excess, this paragraph ‎6(e)
shall apply to such excess.

7.             The
Sponsor and each Insider represents and warrants that it, he or she has never been suspended or expelled from membership
in any securities or commodities exchange or association or had a securities or commodities license or registration denied, suspended
or revoked. Each Insider represents that such Insider’s biographical information furnished to SPAC (including any such information
included in the Prospectus) is true and accurate in all respects and does not omit any material information with respect to the
Insider’s background. The Sponsor and each Insider represents and warrants that: it, he or she is not subject to or a respondent
in any legal action for, any injunction, cease-and-desist order or order or stipulation to desist or refrain from any act or practice
relating to the offering of securities in any jurisdiction; it, he or she has never been convicted of, or pleaded guilty to, any
crime (i) involving fraud, (ii) relating to any financial transaction or handling of funds of another person, or (iii) pertaining
to any dealings in any securities and it, he or she is not currently a defendant in any such criminal proceeding.

 

8.             Except
as disclosed on Schedule 6.07 (Brokers’ Fees) of the Merger Agreement, neither the Sponsor nor any Insider nor any affiliate
of the Sponsor or any Insider, nor any director or officer of SPAC,
shall receive from SPAC any finder’s fee, reimbursement, consulting fee, monies in respect
of any repayment of a loan or other compensation prior to, or in connection with any services rendered in order to effectuate
the consummation of SPAC’s initial Business Combination (regardless of the type of transaction that it is), other than the
following, none of which will be made from the proceeds held in the Trust Account prior to the completion of the initial Business
Combination and each of which shall, as of and in connection with the Closing, be paid off in full and no further liabilities
or obligations in respect thereof shall be due and owing by SPAC or the Company or any of
its Subsidiaries from and after the Closing: repayment of an aggregate of up to $600,000 in loans made to SPAC by
the Sponsor to cover expenses related to the organization of SPAC and the Public Offering;
payment to M. Klein and Company or another affiliate of the Sponsor for customary financial advisory fees (provided that if the
transactions contemplated by the Merger Agreement are completed, no such financial advisory fees shall be payable); payment to
M. Klein Associates, Inc. for office space and related support services for a total of $50,000 per month; reimbursement for any
reasonable out-of-pocket expenses related to identifying, investigating and consummating an initial Business Combination; and
repayment of loans, if any, and on such terms as to be determined by SPAC from time to time,
made by the Sponsor or certain of SPAC’s officers and directors to finance transaction costs in connection with an intended
initial Business Combination, provided, that, if SPAC does not consummate an initial Business
Combination, a portion of the working capital held outside the Trust Account may be used by SPAC to
repay such loaned amounts so long as no proceeds from the Trust Account are used for such repayment. Up to $1,500,000 of such
loans may be convertible into warrants of the post Business Combination entity at a price of $1.00 per warrant at the option of
the lender. Such warrants would be identical to the Private Placement Warrants, including as to exercise price, exercisability
and exercise period and included in the up to 44,350,000 warrants to be issued to the Sponsor as provided in Section 6.11(b) of
the Merger Agreement. During the period commencing on the date hereof and ending on the earlier of (i) the consummation
of the Closing and (ii) the valid termination of the Merger Agreement, the Sponsor and each Insider agrees not to enter into,
modify or amend any Contract between or among the Sponsor, any Insider, anyone related by blood, marriage or adoption to any Insider
or any Affiliate of any such Person (other than SPAC or any of its Subsidiaries), on the one hand, and SPAC or any of its Subsidiaries,
on the other hand, that would contradict, limit, restrict or impair (x) any party’s ability to perform or satisfy any obligation
under this Sponsor Agreement or (y) the Company’s or SPAC’s ability to perform or satisfy any obligation under the
Merger Agreement.

into this Sponsor Agreement and, as applicable, to serve as an officer and/or a director on the board of directors of SPAC.
