 Re: Initial Public Offering

 Ladies and Gentlemen: 
 This letter (this
“Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) to be entered into by and between Fortress Value Acquisition Corp. IV, a
Delaware corporation (the “Company”), and Deutsche Bank Securities Inc., BofA Securities, Inc. and PJT Partners LP, as representatives (the “Representatives”) of the several underwriters (collectively,
the “Underwriters”), relating to an underwritten initial public offering (the “Public Offering”), of 69,000,000 of the Company’s units (including up to 9,000,000 units that may be purchased to
cover over-allotments, if any) (the “Units”), each comprised of one share of the Company’s Class A common stock, par value $0.0001 per share (the “Common Stock”), and one-eighth of one redeemable warrant. Each whole warrant (each, a “Warrant”) entitles the holder thereof to purchase one share of Common Stock at a price of $11.50 per share, subject to
adjustment. The Units shall be sold in the Public Offering pursuant to a registration statement on Form S-1 and prospectus (the “Prospectus”) filed by the Company with the Securities
and Exchange Commission (the “Commission”) and the Company shall apply to have the Units listed on the New York Stock Exchange. Certain capitalized terms used herein are defined in paragraph 11 hereof. 

In order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering and for
other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Fortress Value Acquisition Sponsor IV LLC, a Delaware limited liability company (the “Sponsor”), and each of the undersigned
individuals, each of whom is a director or member of the Company’s board of directors and/or management team (each, an “Insider” and collectively, the “Insiders”), hereby agrees with the Company
as follows: 
 1. The Sponsor and each Insider agrees with the Company that if the Company seeks stockholder approval of a proposed Business
Combination, then in connection with such proposed Business Combination, it, he or she shall (i) vote any shares of Capital Stock owned by it, him or her in favor of any proposed Business Combination and (ii) not redeem any shares of
Capital Stock owned by it, him or her in connection with such stockholder approval. 
 2. The Sponsor and each Insider hereby agrees with the
Company that in the event that the Company fails to consummate a Business Combination within 24 months from the closing of the Public Offering, or such later period approved by the Company’s stockholders in accordance with the Company’s
amended and restated certificate of incorporation, the Sponsor and each Insider shall take all reasonable steps to cause the Company to (i) cease all operations except for 

  
 1 

 
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 earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes (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 liquidation distributions, if any), and (iii) as promptly as reasonably possible following such
redemption, subject to the approval of the Company’s remaining stockholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of
creditors and other requirements of other applicable law. The Sponsor and each Insider agrees to not propose any amendment (i) to the Company’s amended and restated certificate of incorporation that would affect the substance or timing of
the Company’s obligation to allow redemption in connection with the Company’s initial Business Combination or to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within 24 months from the closing
of the Public Offering or (ii) with respect to any other provision of the Company’s amended and restated certificate of incorporation relating to stockholders’ rights or pre-initial Business
Combination activity, unless the Company provides its Public Stockholders with the opportunity to redeem their shares of Common Stock 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 earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes, divided by the number of then outstanding Offering
Shares. 
 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 the Company as a result of any liquidation of the Company with respect to the Founder Shares held by it, him or her. The Sponsor and each Insider hereby further waives, 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 the Company to purchase shares of Common Stock (although the Sponsor and the Insiders and their respective affiliates shall be entitled to redemption
and liquidation rights with respect to any Offering Shares they hold if the Company fails to consummate a Business Combination within 24 months from the date of the closing of the Public Offering). The Sponsor and each Insider hereby further waives,
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 a stockholder vote to approve an amendment to the Company’s amended and restated certificate of
incorporation (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial Business Combination or to redeem 100% of the Offering Shares if the Company does not
complete a Business Combination within 24 months from the closing of the Public Offering or (B) with respect to any other provision relating to stockholders’ rights or pre-Business Combination
activity. 
  

  
 2 

 3. Notwithstanding the provisions set forth in 7(a) and (b) below, during the period
commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, the Sponsor and each Insider shall not, without the prior written consent of the Representatives, (i) sell, offer to sell, contract or agree to sell,
hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of
Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules and regulations of the Commission promulgated thereunder, with respect to any Units, shares of Common
Stock, Founder Shares, Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by it, him or her, (ii) enter into any swap or other arrangement that transfers to another, in whole or in
part, any of the economic consequences of ownership of any Units, shares of Common Stock, Founder Shares, Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by it, him or her, whether any
such transaction is to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction, including the filing of a registration statement, specified in clause (i) or (ii).
The provisions of this paragraph will not apply (i) to the transfer of Founder Shares to any independent director appointed or elected to the Company’s board of directors after the Public Offering or (ii) if the release or waiver is
effected solely to permit a transfer not for consideration and, in each case the transferee has agreed in writing to be bound by the same terms described in this Letter Agreement to the extent and for the duration that such terms remain in effect at
the time of the transfer. In addition, the provisions of this paragraph will not in any way limit the ability of the Sponsor to enter into agreements with employees of the Sponsor or any of its affiliates or employees of Fortress Investment Group
LLC or any of its affiliates relating to the transfer of direct or indirect interests in the Founder Shares to such persons, provided that such transfer is not effected until the expiration of the Founder Shares
Lock-Up Period (as defined below), or admitting such persons as members of the Sponsor, as long as, to the extent any reporting obligation under Section 16 of the Exchange Act is triggered as a result of
such agreements, any related filing under Section 16 of the Exchange Act includes a practical explanation as to the nature of such agreement. 

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) agrees to indemnify and hold harmless the Company 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 the Company may become subject as a result of any claim by (i) any third party for services
rendered (other than the Company’s independent public accountants) or products sold to the Company or (ii) a prospective target business with which the Company has discussed entering into a transaction agreement (a
“Target”); provided, however, that such indemnification of the Company by the Sponsor shall apply only to the extent necessary to ensure that such claims by a third party for services rendered (other than the
Company’s independent public accountants) or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below (i) $10.00 per Offering Share or (ii) such lesser amount per Offering Share held in the
Trust Account due to reductions in the value of the trust assets as of the date of the liquidation of the Trust Account, in each case, net of the amount of interest earned on the property in the Trust Account which may be withdrawn to pay its taxes,
except as to any claims by a third party (including a Target) who executed a waiver of any and all rights to seek access to the Trust 

  
 3 

 
Account and except as to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended. In the
event that any such executed waiver is deemed to be unenforceable against such third party, the Sponsor shall not be responsible to the extent of any liability for such third party claims. The Sponsor shall have the right to defend against any such
claim with counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the Sponsor, the Sponsor notifies the Company in writing that it shall undertake such defense. For the
avoidance of doubt, none of the Company’s officers or directors will indemnify the Company for claims by third parties, including, without limitation, claims by vendors and prospective target businesses. 

5. To the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 9,000,000 Units within 45
days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees to forfeit, at no cost, a number of Founder Shares in the aggregate equal to 2,250,000 multiplied by a fraction, (i) the numerator of which is
9,000,000 minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 9,000,000. The forfeiture will be adjusted to the extent that the over-allotment option is
not exercised in full by the Underwriters so that the number of Founder Shares will equal an aggregate of 20.0% of the Company’s issued and outstanding Capital Stock after the Public Offering. To the extent that the size of the Public Offering
is increased or decreased, the Company will effect a stock dividend, share contribution back to capital or other appropriate mechanism, as applicable, with respect to the Founder Shares immediately prior to the consummation of the Public Offering in
such amount as to maintain the number of Founder Shares prior to the Public Offering at 20% of the Company’s issued and outstanding Capital Stock of the Public Offering. In connection with such increase or decrease in the size of the Public
Offering, then (A) the references to 9,000,000 in the numerator and denominator of the formula in the first sentence of this paragraph shall be changed to a number equal to 15% of the number of shares included in the Units issued in the Public
Offering and (B) the reference to 2,250,000 in the formula set forth in the immediately preceding sentence shall be adjusted to such number of Founder Shares that the Sponsor would have to return to the Company in order for the number of
Founder Shares to equal an aggregate of 20.0% of the Company’s issued and outstanding Capital Stock after the Public Offering. 
 6. The
Sponsor and each Insider hereby agrees and acknowledges that: (i) the Underwriters and the Company would be irreparably injured in the event of a breach by such Sponsor or Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5,
7(a), 7(b), and 9 of this 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. 
 7. (a) The Sponsor and each Insider agrees
that it, he or she shall not Transfer any Founder Shares (or shares of Common Stock issuable upon conversion thereof) until the earliest to occur of: (A) one year after the completion of the Company’s initial Business Combination;
(B) subsequent to the Company’s initial Business Combination, if the last reported sale price of the shares of 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 with any 30-trading day period commencing at least 150 days after the Company’s initial Business 

  
 4 

 
Combination; and (C) the date following the completion of the Company’s initial Business Combination on which the Company completes a liquidation, merger, stock exchange, reorganization
or other similar transaction that results in all of the Company’s Public Stockholders having the right to exchange their share of common stock for cash, securities or other property (the “Founder Shares Lock-up Period”). 
 (b) The Sponsor and each Insider agrees that it, he or she shall not
Transfer any Private Placement Warrants (or shares of Common Stock issued or issuable upon the conversion of the Private Placement Warrants), until 30 days after the completion of the Company’s initial Business Combination (the
“Private Placement Warrants Lock-up Period”, together with the Founder Shares Lock-up Period, the
“Lock-up Periods”). 
 (c) Notwithstanding the provisions set forth in
paragraphs 7(a) and (b), Transfers of the Founder Shares, Private Placement Warrants and shares of Common Stock issued or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares and that are held by the
Sponsor, Insider or any of their permitted transferees (that have complied with this paragraph 7(c)), are permitted (a) to the Company’s officers, directors or employees, any affiliates or family members of any of the Company’s
officers, directors or employees, any members or employees of the Sponsor, or any affiliates of the Sponsor; (b) in the case of an individual, by gift to a member of the individual’s immediate family or to a trust, the beneficiary of which
is a member of the individual’s immediate family or an affiliate of such person, or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (d) in the
case of an individual, pursuant to a qualified domestic relations order; (e) by private sales or transfers made in connection with the consummation of a Business Combination at prices no greater than the price at which the securities were
originally purchased; (f) in the event of the Company’s liquidation prior to the completion of an initial Business Combination; (g) by virtue of the laws of the State of Delaware or the Sponsor’s limited liability company
agreement upon dissolution of the Sponsor; and (h) in the event of the Company’s liquidation, merger, capital stock exchange, reorganization or other similar transaction which results in all of the Company’s stockholders having the
right to exchange their shares of Common Stock for cash, securities or other property subsequent to the completion of the Company’s initial Business Combination; provided, however, that in the case of clauses (a) through (e), these
permitted transferees must enter into a written agreement agreeing to be bound by the restrictions herein. 
 8. 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’s biographical information furnished to the Company (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 such Insider’s
background. The Sponsor’s and each Insider’s questionnaire furnished to the Company is true and accurate in all respects. 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. 

  
 5 

 9. Except as disclosed in the Prospectus, neither the Sponsor not any Insider nor any
affiliate of the Sponsor or any Insider, shall receive from the Company 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 the Company’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 Company’s initial Business Combination: repayment of a loan and advances of up to an aggregate of $300,000 made to the Company by the Sponsor to cover offering-related and organizational expenses; payment to an affiliate of
the Sponsor for office space, administrative and support services for a total of $20,000 per month; reimbursement for any 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 the Company from time to time, made by the Sponsor or any of the Company’s officers or directors to finance
transaction costs in connection with an intended initial Business Combination, provided, that, if the Company does not consummate an initial Business Combination, a portion of the working capital held outside the Trust Account may be used by the
Company 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 $2.00 per warrant
at the option of the lender. Such warrants would be identical to the Private Placement Warrants. 
 10. The Sponsor and each Insider has full
right and power, without violating any agreement to which it, he or she is bound (including, without limitation, any non-competition or non-solicitation agreement with
any employer or former employer), to enter into this Letter Agreement and, as applicable, to serve as a director on the board of directors of the Company and hereby consents to being named in the Prospectus as a director of the Company. 

11. As used herein, (i) “Business Combination” shall mean a merger, capital stock exchange, asset acquisition, stock
purchase, reorganization or similar business combination, involving the Company and one or more businesses; (ii) “Capital Stock” shall mean, collectively, the Common Stock and the Founder Shares; (iii) “Founder
Shares” shall mean the 17,250,000 shares of the Company’s Class F common stock, par value $0.0001 per share (up to 2,250,000 of which are subject to forfeiture depending on the extent to which the over-allotment option is not
exercised by the Underwriters); (iv) “Private Placement Warrants” shall mean the Warrants to purchase up to 7,500,000 shares of Common Stock of the Company (or 8,400,000 shares of Common Stock if the over-allotment
option is exercised in full) that the Sponsor has agreed to purchase for an aggregate purchase price of $15,000,000 in the aggregate (or $16,800,000 if the over-allotment option is exercised in full), or $2.00 per Warrant, in a private placement
that shall occur simultaneously with the consummation of the Public Offering; (v) “Public Stockholders” shall mean the holders of securities issued in the Public Offering; (vi) “Trust
Account” shall mean the trust fund into which a portion of the net proceeds of the Public Offering shall be deposited; and (vii) “Transfer” shall mean the (a) sale of, offer to sell, contract or agreement to
sell, hypothecate, pledge, grant of any option to purchase or otherwise dispose of or agreement to dispose of, directly or indirectly, or establishment or increase of a put equivalent position or liquidation with respect to or decrease of a call
equivalent position within the 

  
 6 

 
meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder with respect to, any security, (b) entry
into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any security, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or
(c) public announcement of any intention to effect any transaction specified in clause (a) or (b). 
 12. This Letter Agreement
constitutes the entire agreement and understanding of the parties hereto in respect of the subject matter hereof and supersedes all prior understandings, agreements, or representations by or among the parties hereto, written or oral, to the extent
they relate in any way to the subject matter hereof or the transactions contemplated hereby. This Letter Agreement may not be changed, amended, modified or waived (other than to correct a typographical error) as to any particular provision, except
by a written instrument executed by all parties hereto. 
 13. No party hereto may assign either this Letter Agreement or any of its rights,
interests, or obligations hereunder without the prior written consent of the other party. Any purported assignment in violation of this paragraph shall be void and ineffectual and shall not operate to transfer or assign any interest or title to the
purported assignee. This Letter Agreement shall be binding on the Sponsor and each Insider and their respective successors, heirs and assigns and permitted transferees. 

14. This Letter Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York, without giving
effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The parties hereto (i) all agree that any action, proceeding, claim or dispute arising out of, or relating in any way
to, this Letter Agreement shall be brought and enforced in the courts of New York City, in the State of New York, and irrevocably submit to such jurisdiction and venue, which jurisdiction and venue shall be exclusive and (ii) waive any
objection to such exclusive jurisdiction and venue or that such courts represent an inconvenient forum. 
 15. Any notice, consent or request
to be given in connection with any of the terms or provisions of this Letter Agreement shall be in writing and shall be sent by express mail or similar private courier service, by certified mail (return receipt requested), by hand delivery or
facsimile transmission. 
 16. This Letter Agreement shall terminate on the earlier of (i) the expiration of the Lock-up Periods and (ii) the liquidation of the Company; provided, however, that this Letter Agreement shall earlier terminate in the event that the Public Offering is not consummated and closed by [•],
2021; provided further that paragraph 4 of this Letter Agreement shall survive such liquidation.

INVESTMENT MANAGEMENT TRUST AGREEMENT 

This Investment Management Trust Agreement (this “Agreement”) is made effective as of [●], 2021 by and between
Fortress Value Acquisition Corp. IV, a Delaware corporation (the “Company”), and Continental Stock Transfer & Trust Company, a New York corporation (the “Trustee”). 

WHEREAS, the Company’s registration statement on Form S-1,
No. 333-[•] (the “Registration Statement”), and prospectus (the “Prospectus”) for the initial public offering of the Company’s units (the
“Units”), each of which consists of one share of the Company’s Class A common stock, par value $0.0001 per share (the “Common Stock”), and
one-eighth of one redeemable warrant, each whole warrant entitling the holder thereof to purchase one share of Common Stock (such initial public offering hereinafter referred to as the
“Offering”), has been declared effective as of the date hereof by the U.S. Securities and Exchange Commission; and 

WHEREAS, the Company has entered into an Underwriting Agreement (the “Underwriting Agreement”) with Deutsche Bank
Securities Inc., BofA Securities, Inc. and PJT Partners LP, as representatives (the “Representatives”) of the several underwriters (the “Underwriters”) named therein; and 

WHEREAS, as described in the Prospectus, $600,000,000 of the gross proceeds of the Offering and sale of the Private Placement Warrants (as
defined in the Underwriting Agreement) (or $690,000,000 if the Underwriters’ over-allotment option is exercised in full) will be delivered to the Trustee to be deposited and held in a segregated trust account located at all times in the United
States (the “Trust Account”) for the benefit of the Company and the holders of shares of the Common Stock included in the Units issued in the Offering as hereinafter provided (the amount to be delivered to the Trustee (and
any interest subsequently earned thereon) is referred to herein as the “Property,” the stockholders for whose benefit the Trustee shall hold the Property will be referred to as the “Public
Stockholders,” and the Public Stockholders and the Company will be referred to together as the “Beneficiaries”); and 

WHEREAS, pursuant to the Underwriting Agreement, a portion of the Property equal to $21,000,000, or $24,150,000 if the Underwriters’
over-allotment option is exercised in full, is attributable to deferred underwriting discounts and commissions that may be payable by the Company to the Underwriters upon the consummation of the Business Combination (as defined below) (the
“Deferred Discount”); and 
 WHEREAS, the Company and the Trustee desire to enter into this Agreement to set forth
the terms and conditions pursuant to which the Trustee shall hold the Property. 

  
 1 

 NOW THEREFORE, IT IS AGREED: 

1. Agreements and Covenants of Trustee. The Trustee hereby agrees and covenants to: 

(a) Hold the Property in trust for the Beneficiaries in accordance with the terms of this Agreement in the Trust Account established by the
Trustee at a branch office of J.P. Morgan Chase Bank, N.A. located in the United States and at a brokerage institution selected by the Trustee that is reasonably satisfactory to the Company; 

(b) Manage, supervise and administer the Trust Account subject to the terms and conditions set forth herein; 

(c) In a timely manner, upon the written instruction of the Company, invest and reinvest the Property in United States government securities
within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended, having a maturity of 185 days or less, or in money market funds meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule 2a-7 promulgated under the Investment Company Act of 1940, as amended (or any successor rule), which invest only in direct U.S. government treasury obligations, as determined by the Company; the Trustee may not
invest in any other securities or assets, it being understood that the Trust Account will earn no interest while account funds are uninvested awaiting the Company’s instructions hereunder and the Trustee may earn bank credits or other
consideration during such periods; 
 (d) Collect and receive, when due, all principal, interest or other income arising from the Property,
which shall become part of the “Property,” as such term is used herein; 
 (e) Promptly notify the Company and
the Representatives of all communications received by the Trustee with respect to any Property requiring action by the Company; 
 (f) Supply
any necessary information or documents as may be requested by the Company (or its authorized agents) in connection with the Company’s preparation of the tax returns relating to assets held in the Trust Account or in connection with the
preparation or completion of the audit of the Company’s financial statements by the Company’s auditors; 
 (g) Participate in any
plan or proceeding for protecting or enforcing any right or interest arising from the Property if, as and when instructed by the Company to do so; 

(h) Render to the Company monthly written statements of the activities of, and amounts in, the Trust Account reflecting all receipts and
disbursements of the Trust Account; 

  
 2 

 (i) Commence liquidation of the Trust Account only after and promptly after (x) receipt
of, and only in accordance with, the terms of a letter from the Company (“Termination Letter”) in a form substantially similar to that attached hereto as either Exhibit A or Exhibit B, as applicable, signed on
behalf of the Company by its Chief Executive Officer, President, Chief Financial Officer, Secretary or Chairman of the Board of Directors of the Company (the “Board”) or other authorized officer of the Company, and complete
the liquidation of the Trust Account and distribute the Property in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes (less up to $100,000 of interest that
may be released to the Company to pay dissolution expenses), only as directed in the Termination Letter and the other documents referred to therein; or (y) the date which is 24 months after the closing of the Offering, if a Termination Letter
has not been received by the Trustee prior to such date, in which case the Trust Account shall be liquidated in accordance with the procedures set forth in the Termination Letter attached as Exhibit B and the Property in the Trust Account,
including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes (less up to $100,000 of interest that may be released to the Company to pay dissolution expenses) shall be distributed to
the Public Stockholders of record as of such date; 
 (j) Upon written request from the Company, which may be given from time to time in a
form substantially similar to that attached hereto as Exhibit C (a “Tax Payment Withdrawal Instruction”), withdraw from the Trust Account and distribute to the Company the amount of interest earned on the Property
requested by the Company to cover any tax obligation owed by the Company as a result of assets of the Company or interest or other income earned on the Property, which amount shall be delivered directly to the Company by electronic funds transfer or
other method of prompt payment, and the Company shall forward such payment to the relevant taxing authority; provided, however, that to the extent there is not sufficient cash in the Trust Account to pay such tax obligation, the
Trustee shall liquidate such assets held in the Trust Account as shall be designated by the Company in writing to make such distribution, so long as there is no reduction in the principal amount per share initially deposited in the Trust Account;
provided, further, that if the tax to be paid is a franchise tax, the written request by the Company to make such distribution shall be accompanied by a copy of the franchise tax bill from the State of Delaware for the Company and a
written statement from the principal financial officer of the Company setting forth the actual amount payable (it being acknowledged and agreed that any such amount in excess of interest income earned on the Property shall not be payable from the
Trust Account). The written request of the Company referenced above shall constitute presumptive evidence that the Company is entitled to said funds, and the Trustee shall have no responsibility to look beyond said request; 

(k) Upon written request from the Company, which may be given from time to time in a form substantially similar to that attached hereto as
Exhibit D (a “Stockholder Redemption Withdrawal Instruction”), the Trustee shall distribute on behalf of the Company the amount requested by the Company to be used to redeem shares of Common Stock from Public
Stockholders properly submitted in connection with a stockholder vote to approve an amendment to the Company’s amended and restated certificate of incorporation (A) to modify the substance or timing of the Company’s obligation to
allow redemption in connection with the Company’s initial Business Combination or to redeem 100% of its public shares of Common Stock if the Company has not consummated an initial Business Combination within such time as is described in the
Company’s amended and restated certificate of incorporation or (B) with respect to any other provision relating to stockholders’ rights or pre-initial Business Combination activity. The written
request of the Company referenced above shall constitute presumptive evidence that the Company is entitled to distribute said funds, and the Trustee shall have no responsibility to look beyond said request; and

 (l) Not make any withdrawals or distributions from the Trust Account other than pursuant to
Sections 1(i), 1(j) or 1(k) above. 
 2. Agreements and Covenants of the Company. The Company hereby agrees and
covenants to: 
 (a) Give all instructions to the Trustee hereunder in writing, signed by the Company’s Chairman of the Board,
President, Chief Executive Officer, Chief Financial Officer or Secretary. In addition, except with respect to its duties under Sections 1(i), 1(j) and 1(k) hereof, the Trustee shall be entitled to rely on, and shall be protected
in relying on, any verbal or telephonic advice or instruction which it, in good faith and with reasonable care, believes to be given by any one of the persons authorized above to give written instructions, provided that the Company shall promptly
confirm such instructions in writing; 
 (b) Subject to Section 4 hereof, hold the Trustee harmless and indemnify
the Trustee from and against any and all documented expenses, including reasonable outside counsel fees and disbursements, or losses suffered by the Trustee in connection with any action taken by it hereunder and in connection with any action, suit
or other proceeding brought against the Trustee involving any claim, or in connection with any claim or demand, which in any way arises out of or relates to this Agreement, the services of the Trustee hereunder, or the Property or any interest
earned on the Property, except for expenses and losses resulting from the Trustee’s gross negligence, fraud or willful misconduct. Promptly after the receipt by the Trustee of notice of demand or claim or the commencement of any action, suit or
proceeding, pursuant to which the Trustee intends to seek indemnification under this Section 2(b), it shall notify the Company in writing of such claim (hereinafter referred to as the “Indemnified
Claim”). The Trustee shall have the right to conduct and manage the defense against such Indemnified Claim; provided that the Trustee shall obtain the consent of the Company with respect to the selection of counsel, which consent
shall not be unreasonably withheld. The Trustee may not agree to settle any Indemnified Claim without the prior written consent of the Company, which such consent shall not be unreasonably withheld. The Company may participate in such action with
its own counsel; 
 (c) Pay the Trustee the fees set forth on Schedule A hereto, including an initial acceptance fee, annual
administration fee, and transaction processing fee which fees shall be subject to modification by the parties from time to time. It is expressly understood that the Property shall not be used to pay such fees unless and until it is distributed to,
or on behalf of, the Company pursuant to Sections 1(i) through 1(k) hereof. The Company shall pay the Trustee the initial acceptance fee and the first annual administration fee at the consummation of the Offering. The Trustee shall
refund to the Company the annual administration fee (on a pro rata basis) with respect to any period after the liquidation of the Trust Account. The Company shall not be responsible for any other fees or charges of the Trustee except as set forth in
this Section 2(c), Schedule A and as may be provided in Section 2(b) hereof; 

  
 4 

 (d) In connection with any vote of the Company’s stockholders regarding a merger,
capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination involving the Company and one or more businesses (the “Business Combination”), provide to the Trustee an affidavit or
certificate of the inspector of elections for the stockholder meeting verifying the vote of such stockholders regarding such Business Combination; 

(e) Provide the Representatives with a copy of any Termination Letter(s) and/or any other correspondence that is sent to the Trustee with
respect to any proposed withdrawal from the Trust Account promptly after it issues the same; 
 (f) Instruct the Trustee to make only those
distributions that are permitted under this Agreement, and refrain from instructing the Trustee to make any distributions that are not permitted under this Agreement; 

(g) Within four (4) business days after the Underwriters exercise the over-allotment option (or any unexercised portion thereof) or such
over-allotment option expires, provide the Trustee with a notice in writing of the total amount of the Deferred Discount, which shall in no event be less than $21,000,000 (or $24,150,000 if the Underwriters’ over-allotment option is exercised
in full); and 
 (h) Expressly provide in any Instruction Letter (as defined in Exhibit A) delivered in connection with a Termination
Letter in the Form of Exhibit A that the Deferred Discount be paid directly to the account or accounts directed by the applicable Underwriters. 

3. Limitations of Liability. The Trustee shall have no responsibility or liability to: 

(a) Imply obligations, perform duties, inquire or otherwise be subject to the provisions of any agreement or document other than this Agreement
and that which is expressly set forth herein; 
 (b) Take any action with respect to the Property, other than as directed in
Section 1 hereof, and the Trustee shall have no liability to any party under this Agreement except for liability arising out of the Trustee’s gross negligence, fraud or willful misconduct; 

(c) Institute any proceeding for the collection of any principal and income arising from, or institute, appear in or defend any proceeding of
any kind with respect to, any of the Property unless and until it shall have received instructions from the Company given as provided herein to do so and the Company shall have advanced or guaranteed to it funds sufficient to pay any expenses
incident thereto; 
 (d) Refund any depreciation in principal of any Property; 

(e) Assume that the authority of any person designated by the Company to give instructions hereunder shall not be continuing unless provided
otherwise in such designation, or unless the Company shall have delivered a written revocation of such authority to the Trustee; 

  
 5 

 (f) The Company or to anyone else for any action taken or omitted by it, or any action
suffered by it to be taken or omitted, in good faith and in the Trustee’s best judgment, except for the Trustee’s gross negligence, fraud or willful misconduct. The Trustee may rely conclusively and shall be protected in acting upon any
order, notice, demand, certificate, opinion or advice of counsel (including counsel chosen by the Trustee, which counsel may be the Company’s counsel), statement, instrument, report or other paper or document (not only as to its due execution
and the validity and effectiveness of its provisions, but also as to the truth and acceptability of any information therein contained) which the Trustee believes, in good faith and with reasonable care, to be genuine and to be signed or presented by
the proper person or persons. The Trustee shall not be bound by any notice or demand, or any waiver, modification, termination or rescission of this Agreement or any of the terms hereof, unless evidenced by a written instrument delivered to the
Trustee, signed by the proper party or parties and, if the duties or rights of the Trustee are affected, unless it shall give its prior written consent thereto; 

(g) Verify the accuracy of the information contained in the Registration Statement; 

(h) Provide any assurance that any Business Combination entered into by the Company or any other action taken by the Company is as contemplated
by the Registration Statement; 
 (i) File information returns with respect to the Trust Account with any local, state or federal taxing
authority or provide periodic written statements to the Company documenting the taxes payable by the Company, if any, relating to any interest income earned on the Property; 

(j) Prepare, execute and file tax reports, income or other tax returns and pay any taxes with respect to any income generated by, and
activities relating to, the Trust Account, regardless of whether such tax is payable by the Trust Account or the Company, including, but not limited to, franchise and income tax obligations, except pursuant to Section 1(j)
hereof; or 
 (k) Verify calculations, qualify or otherwise approve the Company’s written requests for distributions pursuant to
Sections 1(i), 1(j) and 1(k) hereof. 
 4. Trust Account Waiver. The Trustee has no right of set-off or any right, title, interest or claim of any kind (“Claim”) to, or to any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust
Account that it may have now or in the future. In the event the Trustee has any Claim against the Company under this Agreement, including, without limitation, under Section 2(b) or Section 2(c)
hereof, the Trustee shall pursue such Claim solely against the Company and its assets outside the Trust Account and not against the Property or any monies in the Trust Account. 

5. Termination. This Agreement shall terminate as follows: 

(a) If the Trustee gives written notice to the Company that it desires to resign under this Agreement, the Company shall use its reasonable
efforts to locate a successor trustee, pending which the Trustee shall continue to act in accordance with this Agreement. At such time that the Company notifies the Trustee that a successor trustee has been appointed by the

  
 6 

 
Company and has agreed to become subject to the terms of this Agreement, the Trustee shall transfer the management of the Trust Account to the successor trustee, including but not limited to the
transfer of copies of the reports and statements relating to the Trust Account, whereupon this Agreement shall terminate; provided, however, that in the event that the Company does not locate a successor trustee within ninety
(90) days of receipt of the resignation notice from the Trustee, the Trustee may submit an application to have the Property deposited with any court in the State of New York or with the United States District Court for the Southern District of
New York and upon such deposit, the Trustee shall be immune from any liability whatsoever; or 
 (b) At such time that the Trustee has
completed the liquidation of the Trust Account and its obligations in accordance with the provisions of Section 1(i) hereof and distributed the Property in accordance with the provisions of the Termination Letter, this
Agreement shall terminate except with respect to Section 2(b). 
 6. Miscellaneous. 

(a) The Company and the Trustee each acknowledge that the Trustee will follow the security procedures set forth below with respect to funds
transferred from the Trust Account. The Company and the Trustee will each restrict access to confidential information relating to such security procedures to authorized persons. Each party must notify the other party immediately if it has reason to
believe unauthorized persons may have obtained access to such confidential information, or of any change in its authorized personnel. In executing funds transfers, the Trustee shall rely upon all information supplied to it by the Company, including,
account names, account numbers, and all other identifying information relating to a Beneficiary, Beneficiary’s bank or intermediary bank. Except for any liability arising out of the Trustee’s gross negligence, fraud or willful misconduct,
the Trustee shall not be liable for any loss, liability or expense resulting from any error in the information or transmission of the funds. 

(b) This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York, without giving effect
to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. 
 (c) This Agreement
contains the entire agreement and understanding of the parties hereto with respect to the subject matter hereof. Except for Sections 1(i), 1(j) and 1(k) hereof (which sections may not be modified, amended or
deleted without the affirmative vote of sixty-five percent (65%) of the then outstanding shares of Common Stock and Class F common stock, par value $0.0001 per share, of the Company, voting together as a single class; provided that no such
amendment will affect any Public Stockholder who has properly elected to redeem his, her or its shares of Common Stock in connection with a stockholder vote sought to amend this Agreement), this Agreement or any provision hereof may only be changed,
amended or modified (other than to correct a typographical error) by a writing signed by each of the parties hereto. 
 (d) The parties
hereto consent to the jurisdiction and venue of any state or federal court located in the City of New York, State of New York, for purposes of resolving any disputes hereunder. AS TO ANY CLAIM, CROSS-CLAIM OR COUNTERCLAIM IN ANY WAY
RELATING TO THIS AGREEMENT, EACH PARTY WAIVES THE RIGHT TO TRIAL BY JURY.

	 	Re:	 Trust Account Termination Letter 

Dear Mr. Wolf and Ms. Gonzalez: 

Pursuant to Section 1(i) of the Investment Management Trust Agreement between Fortress Value Acquisition Corp. IV (the
“Company”) and Continental Stock Transfer & Trust Company (the “Trustee”), dated as of [●], 2021 (the “Trust Agreement”), this is to advise you that the Company
has entered into an agreement with (the “Target Business”) to consummate a business combination with Target Business (the “Business Combination”) on or about [insert date]. The Company shall notify you
at least seventy-two (72) hours in advance of the actual date (or such shorter time period as you may agree) of the consummation of the Business Combination (the “Consummation
Date”). Capitalized terms used but not defined herein shall have the meanings set forth in the Trust Agreement. 
 In
accordance with the terms of the Trust Agreement, we hereby authorize you to commence to liquidate all of the assets of the Trust Account, and to transfer the proceeds into the above-referenced account at J.P. Morgan Chase Bank, N.A. to the effect
that, on the Consummation Date, all of the funds held in the Trust Account will be immediately available for transfer to the account or accounts that the Company, and solely with respect to the Deferred Discount, the [Underwriters], shall direct on
the Consummation Date. It is acknowledged and agreed that while the funds are on deposit in the trust operating account at J.P. Morgan Chase Bank, N.A. awaiting distribution, neither the Company nor the Underwriters will earn any interest or
dividends. 
 On the Consummation Date (i) counsel for the Company shall deliver to you written notification that the Business
Combination has been consummated, or will be consummated substantially, concurrently with your transfer of funds to the accounts as directed by the Company (the “Notification”) and (ii) the Company shall deliver to you
(a) [an affidavit] [a certificate] of the Chief Executive Officer of the Company, which verifies that the Business Combination has been approved by a vote of the Company’s stockholders, if a vote is held and (b) [joint written instruction
signed by the Company and the Underwriters] with respect to the transfer of the funds held in the Trust Account, including payment of amounts owed to public stockholders who have properly exercised their redemption rights and express instructions to
pay the Deferred Discount from the Trust Account directly to the account or accounts directed by the Underwriters (the “Instruction Letter”). You are hereby directed and authorized to transfer the funds held in the Trust
Account immediately upon your receipt of the Notification and the 

  
 12 

 
Instruction Letter, in accordance with the terms of the Instruction Letter. In the event that certain deposits held in the Trust Account may not be liquidated by the Consummation Date without
penalty, you will notify the Company in writing of the same and the Company shall direct you as to whether such funds should remain in the Trust Account and be distributed after the Consummation Date to the Company. Upon the distribution of all the
funds, net of any payments necessary for reasonable unreimbursed expenses related to liquidating the Trust Account, your obligations under the Trust Agreement shall be terminated. 

In the event that the Business Combination is not consummated on the Consummation Date described in the notice thereof and we have not
notified you on or before the original Consummation Date of a new Consummation Date, then upon receipt by the Trustee of written instructions from the Company, the funds held in the Trust Account shall be reinvested as provided in Section 1(c)
of the Trust Agreement on the business day immediately following the Consummation Date as set forth in the notice as soon thereafter as possible.
