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 Genesis Park Acquisition Corp., a Cayman Islands exempted company (the “Company”), and Jefferies LLC, as representative (the
“Representative”) of the several underwriters (each, an “Underwriter” and collectively, the “Underwriters”), relating to an underwritten initial public offering (the
“Public Offering”), of up to 17,250,000 of the Company’s units (including up to 2,250,000 units that may be purchased to cover over-allotments, if any) (the “Units”), each comprised of one
Class A ordinary share of the Company, par value $0.0001 per share (the “Ordinary Shares”), and one-half of one redeemable warrant. Each whole warrant (each, a
“Warrant”) entitles the holder thereof to purchase one Ordinary Share at a price of $11.50 per share, subject to adjustment. The Units will 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 Units have been approved to be
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, Genesis Park Holdings (the
“Sponsor”) and each of the undersigned individuals, each of whom is a 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 hereby agrees that if the
Company seeks shareholder approval of a proposed Business Combination, then in connection with such proposed Business Combination, it, he or she shall (i) vote any Shares owned by it, him or her in favor of such proposed Business Combination
and (ii) not redeem any Ordinary Shares owned by it, him or her in connection with such shareholder approval. If the Company engages in a tender offer in connection with any proposed Business Combination, each Insider agrees that he or she will
not seek to sell his or her Ordinary Shares to the Company in connection with such tender offer. 
 2. The Sponsor and each Insider hereby
agrees that in the event that the Company fails to consummate a Business Combination within the timeframe set forth in the Company’s amended and restated memorandum and articles of association, as amended from time to time (the
“Articles”), the Sponsor and each Insider shall take all reasonable steps to cause the Company 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 Ordinary Shares 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 Shareholders’ rights as shareholders of the
Company (including the right to receive further liquidation distributions, if any), 

 
subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s
board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and other requirements of applicable law. The Sponsor and each Insider agree not to
propose any amendment to the Articles (a) to modify the substance or timing of the Company’s obligation to provide for the redemption of the Offering Shares in connection with an initial Business Combination or to redeem 100% of such
shares if the Company has not consummated an initial Business Combination within such time as is described in the Articles or (b) with respect to any other material provisions relating to shareholders’ rights or pre-initial Business Combination activity, unless the Company provides its Public Shareholders 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 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 agree to waive their respective redemption rights with respect to Shares owned by them in connection with a shareholder vote to approve an
amendment to the Articles (1) to modify the substance or timing of the Company’s obligation to provide for the redemption of the Offering Shares in connection with an initial Business Combination or to redeem 100% of such shares if the
Company has not consummated an initial Business Combination within such time as is described in the Articles or (2) with respect to any other material provisions relating to shareholders’ rights or
pre-initial Business Combination activity. 
 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 Ordinary Shares 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 shareholder vote to approve such Business Combination or in the context of a tender offer made by the Company to purchase Ordinary Shares (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 the Company fails to consummate a Business Combination within the timeframe set forth in the Articles). 

3. 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 Representative, (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, Warrants or any securities convertible into, or exercisable, or exchangeable for, Ordinary Shares 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, Warrants or any securities convertible into, or exercisable, or exchangeable for, Ordinary Shares
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 specified in clause (i) or (ii). Each of the
Insiders and the Sponsor acknowledges and agrees that, prior to the effective date of any release or waiver of the restrictions set forth in this paragraph 3 or paragraph 7 below, the Company shall announce the impending release or waiver by press
release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted shall only be effective two business days after the publication date of such press release. The
provisions of this paragraph will not apply if (i) the release or waiver is effected solely to permit a transfer of securities that is not for consideration and (ii) 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. 

  
 - 2 - 

 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 (other than the Company’s independent public accountants) for services rendered or products sold to the Company or (ii) a prospective target business with which the Company has entered into a letter of intent,
confidentiality or other similar agreement for a Business Combination 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 the lesser
of (i) $10.15 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 $10.15 per Offering Share, due to reductions in the value of the trust
assets, less taxes payable, except as to any claims by a third party (including a Target) who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) 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. 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 Targets. 

5. To the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 2,250,000 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 562,500 multiplied by a fraction, (i) the numerator of which is
2,250,000 minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 2,250,000. The forfeiture will be adjusted to the extent that the over-allotment option is
not exercised in full by the Underwriters so that the Initial Shareholders will own an aggregate of 20.0% of the Company’s issued and outstanding Shares after the Public Offering. 

6.         (a) Each Insider who is an officer of the Company hereby agrees not to become an officer or
director of any other special purpose acquisition company with a class of securities registered under the Exchange Act, until the Company has entered into a definitive agreement with respect to a Business Combination or unless the Company has failed
to complete a Business Combination within the timeframe set forth in the Articles. 
 (b) 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 the Sponsor or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 6(a), 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. 

  
 - 3 - 

 7.         (a) The Sponsor and each Insider agrees
that it, he or she shall not Transfer any Founder Shares (or Ordinary Shares issuable upon conversion thereof) until the earlier of (A) one year after the completion of the Company’s initial Business Combination or (B) subsequent to
the Company’s initial Business Combination, (x) if the reported closing price of the Ordinary Shares equals or exceeds $12.00 per share (as adjusted for share splits, share dividends, reorganizations, recapitalizations and the like) for
any 20 trading days within any 30-trading day period commencing at least 180 days after the consummation of the Company’s initial Business Combination, or (y) the date on which the Company completes
a liquidation, merger, capital share exchange, reorganization or other similar transaction that results in all of the Company’s shareholders having the right to exchange their Ordinary Shares 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 Ordinary Shares issued or issuable upon the exercise of the Private Placement Warrants) until 30 days after the completion of a 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 Ordinary Shares issued or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares and that are held by the Sponsor, any Insider or any of their permitted transferees (that have complied
with this paragraph 7(c)), are permitted (a) to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, any members of the Sponsor or any affiliates of the Sponsor;
(b) in the case of an individual, by gift to a member of such individual’s immediate family or to a trust, the beneficiary of which is a member of such individual’s immediate family, an affiliate of such individual or to a charitable
organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death of such 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 any forward purchase agreement or similar arrangement or in connection with the consummation of an initial Business Combination at prices no greater than the price at which the shares or warrants were originally
purchased; (f) in the event of the Company’s liquidation prior to the completion of an initial Business Combination; or (g) by virtue of the laws of the Cayman Islands or the organizational documents of the Sponsor upon dissolution of
the Sponsor; provided, however, that in the case of clauses (a) through (e) or (g), these permitted transferees must enter into a written agreement with the Company agreeing to be bound by the transfer restrictions herein and the other
restrictions contained in this Agreement and by the same agreements entered into by the Sponsor with respect to such securities (including provisions relating to voting, the Trust Account and liquidating distributions). 

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 the Insider’s background. The Sponsor 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. 

  
 - 4 - 

 9.         (a) Except as disclosed in the
Prospectus, neither the Sponsor nor any Insider nor any affiliate of the Sponsor or any Insider, nor any director or officer of the Company, 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 initial Business Combination: repayment of a loan and advances up to an aggregate of $300,000 made to the Company by the
Sponsor; 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 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. 
 (b) Commencing on the effective date of the Prospectus for the Offering and
continuing until the earlier of (i) the consummation by the Company of a Business Combination or (ii) the Company’s liquidation as described in the Prospectus, Genesis Park II, LP, the managing member of the Sponsor, shall make
available to the Company, in an amount not to exceed $15,000 per month, certain office space and administrative and support services as may be required by the Company from time to time, situated at 2000 Edwards St., Suite B, Houston, TX 77007 (or
any successor locations). 
 10. The Sponsor and each Insider has full right and power, without violating any agreement to which it 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 an officer and/or a director of the Company and hereby consents to being named in the Prospectus as an officer and/or a director of the Company. 

11. As used herein, (i) “Business Combination” shall mean a merger, share exchange, asset acquisition, share purchase,
reorganization or similar business combination, involving the Company and one or more businesses; (ii) “Shares” shall mean, collectively, the Ordinary Shares and the Founder Shares; (iii) “Founder
Shares” shall mean the 4,312,500 shares of the Company’s Class B ordinary shares, par value $0.0001 per share, held by the Sponsor (up to an aggregate of 562,500 shares of which are subject to complete or partial forfeiture by

 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.

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. 
 18. Any notice, consent or request

 Exhibit 10.3 

INVESTMENT MANAGEMENT TRUST AGREEMENT 

This Investment Management Trust Agreement (this “Agreement”) is made effective as of [•], 2020 by and between
Genesis Park Acquisition Corp., a Cayman Islands exempted company (the “Company”), and Continental Stock Transfer & Trust Company, a New York corporation (the “Trustee”). 

WHEREAS, the Company’s registration statement on Form S-1, File No. 333-249066 (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 of the Company’s Class A ordinary shares, par value $0.0001 per share (the “Ordinary Shares”), and one-half of
one redeemable warrant, each whole warrant entitling the holder thereof to purchase one Ordinary Share (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 Jefferies LLC as representative (the “Representative”) of the several underwriters (the “Underwriters”) named therein; and 

WHEREAS, as described in the Prospectus, $152,250,000 of the gross proceeds of the Offering and sale of the Private Placement Warrants
(as defined in the Underwriting Agreement) (or $175,087,500 if the Underwriters’ over-allotment option to purchase additional Units 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 the Ordinary Shares 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 shareholders for whose benefit the Trustee shall hold the Property will be referred to as the
“Public Shareholders,” and the Public Shareholders 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 $5,250,000, or $6,037,500 if the Underwriters’
over-allotment option to purchase additional Units is exercised in full, is attributable to deferred underwriting discounts and commissions that will be payable by the Company to the Underwriters upon and concurrently with 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. 

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 in the United States at J.P. Morgan Chase Bank, N.A. (or at another U.S.-chartered commercial bank with consolidated assets of $100 billion or more), 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; 
 (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 Representative 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; 
 (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; 

(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, Chief Financial Officer, Chairman of the board of directors of the Company (the “Board”) or other authorized officer of the Company and, in the case of Exhibit A, acknowledged and agreed to by the
Representative, 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 to pay dissolution expenses), only as directed in the Termination Letter and the other documents referred to therein, or (y) upon the date which is the later of (i) 18 months after the closing of the Offering and
(ii) such later date as may be approved by the Company’s shareholders in accordance with the Company’s amended and restated memorandum and articles of association, 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 to pay dissolution expenses) shall be distributed to the Public Shareholders 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, 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

  
 2 

 
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. The written request of the Company in the form
of Exhibit C 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 (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); 
 (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, the Trustee shall distribute to the Public Shareholders of record as of such date the amount requested by the Company to be used to
redeem Ordinary Shares from Public Shareholders properly submitted in connection with a shareholder vote to approve an amendment to the Company’s amended and restated memorandum and articles of association (a) to modify the substance or
timing of the Company’s obligation to provide for the redemption of its public Ordinary Shares in connection with an initial Business Combination or to redeem 100% of such shares if the Company has not consummated an initial Business
Combination within such time as is described in the Company’s amended and restated memorandum and articles of association or (b) with respect to any other material provisions relating to shareholders’ 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 Section 1(i), (j) or (k) above. 
 2. AGREEMENTS AND COVENANTS OF THE

Company’s Chairman of the Board, Chief Executive Officer, Chief Financial Officer or other authorized officer of the Company. 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;

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 or delayed. 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 or delayed. The Company may participate in such action with its own counsel;

Section 2(c), Schedule A and as may be provided in Section 2(b) hereof; 
 (d) In
connection with any vote of the Company’s shareholders regarding a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination involving the Company and one or more businesses (the

the account or accounts directed by the Representative on behalf of the Underwriters prior to any transfer of the funds held in the Trust Account to the Company or any other person; 

(g) 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; and 
 (h) 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
$5,250,000.

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; 

  
 4 

 (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; 
 (f) The
other parties hereto 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 reasonable 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

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 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 

  
 5 

 
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 herein 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. This Agreement may be executed in several original or facsimile counterparts, each one of which shall constitute an original, and
together shall constitute but one instrument. 
 (c) This Agreement contains the entire agreement and understanding of the parties hereto
with respect to the subject matter hereof. Except for Section 1(i), 1(j) and 1(k) hereof (which sections may not be modified, amended or deleted without the affirmative vote of two-thirds of the then outstanding Ordinary Shares and Class B ordinary shares, par value $0.0001 per share, of the Company, voting together as a single class; provided that no such amendment
will affect any Public Shareholder who has properly elected to redeem his or her Ordinary Shares in connection with a shareholder vote to amend this Agreement (A) to modify the substance or timing of the Company’s obligation to provide for
the redemption of the Public Shares in connection with an initial Business Combination or an Amendment or to redeem 100% of its Ordinary Shares if the Company does not complete its initial Business Combination within the time frame specified in the
Company’s amended and restated memorandum and articles of association or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial Business Combination
activity), 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 Genesis Park Acquisition Corp. (the
“Company”) and Continental Stock Transfer & Trust Company (the “Trustee”), dated as of [•], 2020 (the “Trust Agreement”), this is to advise you that the Company
has entered into an agreement with [insert name] (the “Target Business”) to consummate a business combination with the 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 of the consummation of the Business Combination (or such shorter time period as you may agree) (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 a segregated account held by you on behalf of the Beneficiaries 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 shall direct on the Consummation Date (including as directed to it by the Representative on behalf of the Underwriters (with respect to the Deferred Discount)). 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, the Company will not 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 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) 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 shareholders, if a vote is held and (b) a joint written instruction signed by the Company and the Representative
with respect to the transfer of the funds held in the Trust Account, including payment of the Deferred Discount to the Representative from the Trust Account (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 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. 

  
 A-1 

 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 such written instruction as soon thereafter as possible.
