Re: Acknowledgement of Satisfaction of Certain Payments under Insider Letter 

Ladies and Gentlemen: 
 Reference is made to that certain Letter
Agreement between GigAcquisitions4, LLC, a Delaware limited liability company (“Sponsor”), Oppenheimer & Co. Inc. (“Oppenheimer”), Nomura Securities International, Inc.
(“Nomura” and together with Oppenheimer, the “Underwriters”) and GigCapital4, Inc., a Delaware corporation (“Acquiror”), dated as of February 8, 2021 (the
“Insider Letter), relating to an underwritten initial public offering of certain units of the Acquiror (the “IPO”). Capitalized terms used and not otherwise defined herein have the meanings ascribed to them
in the Insider Letter. 
 Section 4 of the Insider Letter permits the Acquiror to make certain payments to the Sponsor, the
Underwriters and their Affiliates. This letter agreement (this “Letter Agreement”), which constitutes the “Sponsor Agreement” contemplated by, and is being delivered to you in accordance with, the Agreement and Plan
of Merger (the “Merger Agreement”), dated as of the date hereof, entered into by and among Acquiror, GigCapital4 Merger Sub Corporation, a Delaware corporation, BigBear.ai Holdings, LLC, a Delaware limited liability company
(the “Company”), and BBAI Ultimate Holdings, LLC, a Delaware limited liability company (“Holdings”), addresses, among other things, the status of such payments in connection with the consummation of
the Transactions (as defined in the Merger Agreement). 
 In order to induce the Company and Holdings to enter into the Merger Agreement,
and to proceed with the Transactions, and in recognition of the benefit that such Transactions will confer upon the undersigned, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged,
notwithstanding anything to the contrary set forth in the Insider Letter, Sponsor hereby agrees with each of Acquiror, Oppenheimer and Nomura as follows: 

1. Sponsor acknowledges and agrees that by its own terms, that certain Administrative Services Agreement, dated as of February 1, 2021
(the “Administrative Services Agreement”), between Acquiror and Sponsor’s Affiliate GigManagement, LLC (the “Management Company”), terminates upon the consummation of the Transactions, and as
such, upon such termination and the payment on the Closing Date (as defined in the Merger Agreement) of all amounts then owed to the Management Company by Acquiror pursuant to the Administrative Services Agreement, neither the Management Company nor
any other Affiliate of Sponsor shall continue to be entitled to receive payments pursuant to the Administrative Services Agreement following the consummation of the Transactions. 

2. The promissory note referred to in paragraph 4(b) of the Insider Letter was repaid in full and extinguished upon the consummation of the
IPO, and Acquiror has no further obligation or other liabilities thereunder. 

 3. Upon payment to Sponsor on the Closing Date of any amounts owed to Sponsor by Acquiror
for the reimbursement of out-of-pocket expenses incurred by Sponsor in connection with certain activities on behalf of Acquiror, such as (a) identifying and
investigating possible business targets and business combinations, (b) advisory fees paid to directors on behalf of Acquiror pertaining to board committee service and extraordinary administrative and analytical services (it being acknowledged
and agreed by the parties hereto, for the avoidance of doubt, that any such fees that are owed to such directors by Acquiror shall remain outstanding until paid by Acquiror in accordance with their terms), and (c) any amounts owed in respect of
obligations pursuant to loans made by Sponsor or its Affiliates to finance transaction costs in connection with an intended Business Combination (collectively, the “Sponsor Expenses”), Acquiror shall owe no further Sponsor
Expenses to Sponsor following the consummation of the Transactions. 
 4. Notwithstanding anything to the contrary set forth in
Section 4(c) of the Insider Letter, Sponsor acknowledges and agrees that no portion of the Sponsor Expenses or any other loan made by Sponsor or any of its Affiliates to the Acquiror will be converted into equity securities of the Ultimate
Surviving Corporation (as defined in the Merger Agreement). 
 5. Sponsor acknowledges and agrees that the Underwriters exercised the
Over-Allotment Option in full, and as such, there was no forfeiture by Sponsor of any of its Founder Shares. Furthermore, Sponsor acknowledges that the size of the IPO was increased, and that as a result, the Acquiror effected a stock dividend
immediately prior to the consummation of the IPO in such amounts as to maintain the ownership of the stockholders of Acquiror prior to the IPO at 20.0% of Acquiror’s total issued and outstanding shares of Common Stock. 

6. Sponsor hereby irrevocably waives any and all rights under Section 5 of the Insider Letter and acknowledges and agrees that Sponsor has
no further rights under or pursuant to Section 5 of the Insider Letter, including any such right to purchase, receive or sell shares of Common Stock or effect or receive a stock dividend or share contribution back to capital. 

7. 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. Each of the undersigned hereby (a) agrees that any action, proceeding or claim against it arising out of or relating in
any way to this Letter Agreement (a “Proceeding”) shall be brought and enforced in the courts of the State of New York of the United States of America for the Southern District of New York, and irrevocably submits to such
jurisdiction, which jurisdiction shall be exclusive, (b) waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum and (c) with respect to Sponsor only, irrevocably agrees to appoint DLA Piper
LLP (US) as agent for the service of process in the State of New York to receive, for the undersigned and on his, her or its own behalf, service of process in any Proceedings. If for any reason such agent is unable to act as such with respect to
Sponsor, Sponsor will promptly notify Acquiror and the Representatives within 30 days and nothing in this Letter Agreement will affect the right of either party to serve process in any other manner permitted by law. 

8. This Letter Agreement, the Insider Letter, the Administrative Services Agreement and the Merger Agreement constitute the entire agreement
and understanding of the parties hereto in respect of the subject matter hereof and supersede 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 and by Holdings. 
 9. This Letter Agreement shall be binding on the undersigned and such person’s
respective successors, heirs, personal representatives and assigns. 

 10. This Letter Agreement may be executed in counterparts, each of which when so executed
shall be deemed to be an original and all of which when taken together shall constitute one and the same instrument. The words “execution,” signed,” “signature,” and words of like import in this Letter Agreement shall
include images of manually executed signatures transmitted by facsimile or other electronic format (including, without limitation, “pdf”, “tif” or “jpg”) and other electronic signatures (including, without limitation,
DocuSign and AdobeSign). The use of electronic signatures and electronic records (including, without limitation, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall be of the same legal
effect, validity and enforceability as a manually executed signature or use of a paper-based record-keeping system to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act,
the New York State Electronic Signatures and Records Act and any other applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act or the Uniform Commercial Code. 

11. The parties hereto acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Letter
Agreement were not performed in accordance with their specific terms or were otherwise breached. The parties hereto acknowledge that Holdings is an express third-party beneficiary of this Letter Agreement. It is accordingly agreed by the parties
hereto that Holdings shall be entitled to seek an injunction or injunctions to prevent breaches or threatened breaches of this Letter Agreement and to enforce specifically the terms and provisions of this Letter Agreement (including all obligations
of Sponsor hereunder), this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise. The parties hereto further agree not to assert that a remedy of specific enforcement pursuant to
this Section 11 is unenforceable, invalid, contrary to applicable law or inequitable for any reason and to waive any defenses in any action for specific performance, including the defense that a remedy at law would be
adequate. The parties acknowledge and agree that this Section 11 is an integral part of the transactions contemplated hereby and without that right, the parties hereto would not have entered into this Letter Agreement.

 Exhibit 10.2 

VOTING AND SUPPORT AGREEMENT 

This VOTING AND SUPPORT AGREEMENT (this “Agreement”) is entered into this 4th day of June, 2021, by and among BBAI Ultimate
Holdings, LLC, a Delaware limited liability company (“Holdings”), BigBear.ai Holdings, LLC, a Delaware limited liability company (“BigBear” and, together with Holdings, the “BigBear
Parties”), and the undersigned Holder (“Holder”). Defined terms used but not otherwise defined herein shall have the respective meanings ascribed thereto in the Merger Agreement (as defined below). 

WHEREAS, as of the date hereof, Holder “beneficially owns” (as such term is defined in Rule
13d-3 promulgated under the Exchange Act) and has the sole power to dispose of (or sole power to cause the disposition of), and the sole power to vote (or sole power to direct the voting of), as applicable,
the number of shares of common stock, par value $0.0001 per share (“Common Stock”) of GigCapital4, Inc., a Delaware corporation (the “Issuer”) (collectively, the “Acquiror Shares”), set forth
on Holder’s signature page hereto (such Acquiror Shares, together with any other Acquiror Shares acquired by Holder or with respect to which Holder otherwise becomes entitled to exercise voting power during the Restricted Period, including any
shares of Common Stock issued upon the exercise of any warrants of the Issuer, the “Covered Shares”); and 
 WHEREAS, the
Issuer, Holdings, BigBear and the other parties named therein will, immediately following the execution of this Agreement, enter into that certain Agreement and Plan of Merger, dated as of June 4, 2021 (as amended, modified, supplemented or
waived from time to time in accordance with its terms, the “Merger Agreement”), pursuant to which, inter alia, a direct, wholly owned subsidiary of the Issuer will be merged with and into BigBear, with BigBear continuing as
the surviving corporation and becoming thereby a wholly-owned subsidiary of the Issuer (the “First Merger”), and immediately thereafter BigBear will be merged with and into Issuer, with Issuer continuing as the surviving corporation
(the “Second Merger”), on the terms and subject to the conditions set forth therein (the First Merger and the Second Merger, together the “Mergers,” and with the other transactions contemplated by the Merger
Agreement, the “Transactions”). 
 WHEREAS, in connection with the Transactions, certain other “accredited
investors” (as such term is defined in Rule 501 under the Securities Act of 1933, as amended have entered into voting and support agreements with the Issuer. 

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions,
herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows: 
 1. Voting Agreement;
Proxy.  
 1.1 Voting Agreement. Holder hereby unconditionally and irrevocably agrees that, during the period from the date hereof
through the date on which this Agreement terminates in accordance with Section 5 (such period, the “Restricted Period”), at any duly called extraordinary general meeting of the stockholders of the Issuer
(or any adjournment or postponement thereof) (the “Special Meeting”), and in any action by written consent of the stockholders of the Issuer requested by the Issuer’s board of directors or undertaken as 

 

 contemplated by the Transactions, Holder shall, if a meeting is held, appear at the meeting, in person or by
proxy, or otherwise cause all of its Covered Shares to be counted as present thereat for purposes of establishing a quorum, and it shall vote or consent (or cause to be voted or consented) (which shall include, for the avoidance of doubt, any
consent in writing (to the extent applicable)), in person or by proxy, all of its Covered Shares (i) in favor of the adoption of the Merger Agreement and approval of the Transactions (including the Mergers), (ii) in favor of the issuance of the
Notes in connection with the First Merger and the Note Financing pursuant to the Note Subscription Agreements (including as required under Nasdaq), (iii) in favor of the amendment and restatement of the Certificate of Incorporation in the form of
the Acquiror Charter attached as Exhibit A to the Merger Agreement, (iv) in favor of the approval of the adoption of the Management Equity Plans, (v) in favor of any other proposals the parties to the Merger Agreement agree are
necessary or desirable to consummate the Transactions, (vi) against any action, proposal, transaction or agreement that would reasonably be expected to result in a breach of any representation, warranty, covenant, obligation or agreement of the
Issuer contained in the Merger Agreement, (vii) in favor of the other Acquiror Stockholder Matters, (viii) for any proposal to adjourn or postpone the applicable Special Meeting to a later date if (and only if) there are not sufficient
votes for approval of the Merger Agreement and the other Acquiror Stockholder Matters on the dates on which such meetings are held, and (ix) except as set forth in the proxy statement of Acquiror in connection with the Transactions (the
“Proxy Statement”), against the following actions or proposals: (A) any Business Combination Proposal or any proposal in opposition to approval of the Merger Agreement or in competition with or inconsistent with the Merger
Agreement; and (B) (1) any change in the present capitalization of the Issuer or any amendment of the Certificate of Incorporation, except to the extent expressly contemplated by the Merger Agreement, (2) any liquidation, dissolution or
other change in the Issuer’s corporate structure or business, (3) any action, proposal, transaction or agreement that would result in a breach in any material respect of any covenant, representation or warranty or other obligation or
agreement of Holder under this Agreement, or (4) any other action or proposal involving the Issuer or any of its subsidiaries that is intended, or would reasonably be expected, to prevent, impede, interfere with, delay, postpone or adversely
affect the Transactions. The obligations of Holder specified in this Section 1.1 shall apply whether or not the First Merger, Second Merger, any of the Transactions or any action described above is recommended by the
Issuer’s board of directors. If the Holder is the beneficial owner, but not the registered holder, of the Covered Shares, Holder agrees to take all actions necessary or requested by BigBear to cause the registered holder and any nominees to
vote all of the Covered Shares in accordance with the terms of this Agreement. 
 1.2 Irrevocable Proxy. Holder hereby revokes any and
all other proxies, consents or powers of attorney in respect of any Covered Shares and agrees that, during the period commencing on the date hereof and ending on the date this Agreement terminates in accordance with
Section 5, Holder hereby irrevocably appoints BigBear or any individual designated by BigBear as Holder’s agent, attorney-in-fact and
proxy (with full power of substitution and resubstitution), for and in the name, place and stead of Holder, to vote (or cause to be voted) Holder’s Covered Shares, in the manner set forth in Section 1.1, at any meeting
of the stockholders of the Issuer, however called, or in connection with any written consent of the stockholders of the Issuer. The power of attorney granted by Holder hereunder is a durable power of attorney coupled with an interest and, if Holder
is an individual, shall survive the death, incapacity, illness, bankruptcy, dissolution or other inability to act of Holder. With respect to Covered Shares as to which Holder is the beneficial owner but not the holder of record, Holder shall cause
any holder 

  
 - 2 - 

 
of record of such Covered Shares to grant to BigBear or any individual designated by BigBear a proxy to the same effect as that described in this Section 1.2. The
exercise of the foregoing proxy shall not relieve Holder from any liability hereunder for failing to comply with the terms of this Agreement. Holder hereby affirms that the proxy set forth in this Section 1.2 is
irrevocable, is coupled with an interest sufficient in Law to support an irrevocable proxy, and is granted in consideration of the BigBear Parties entering into the Merger Agreement; provided, that, for the avoidance of doubt, the proxy set
forth in this Section 1.2 shall terminate automatically upon termination of this Agreement. The vote of the proxyholder shall control in any conflict between the vote by the proxyholder of Holder’s Covered Shares and a
vote by Holder of Holder’s Covered Shares. 
 2. No Redemption. Holder hereby unconditionally and irrevocably agrees that during
the Restricted Period, Holder shall not, and shall cause its controlled Affiliates not to, elect to redeem or tender or submit for redemption the Holder’s Covered Shares pursuant to or in connection with the Acquiror Stockholder Redemption or
otherwise in connection with the Transactions. 
 3. Representations, Warranties and Agreements.

creditors generally, and (ii) principles of equity, whether considered at law or equity. 
 3.1.3 The execution, delivery and
performance by Holder of this Agreement and the consummation of the transactions contemplated herein do not and will not (i) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under,

agreement, lease, license or other agreement or instrument to which Holder or any of its subsidiaries is a party or by which Holder or any of its subsidiaries is bound or to which Holder’s Covered Shares or any other property or assets of

of) or to vote (or to direct the voting of) any Covered Shares (other than, for the avoidance of doubt, BigBear or its designated individual pursuant to Section 1.2). Holder has good and valid title to the Covered Shares denoted as being owned
by Holder on the signature page hereto, free and clear of any and all Liens other than those created or permitted by this Agreement, those imposed by applicable law, including federal and state securities laws, and those disclosed in the public
securities filings of the Issuer, and are not subject to any preemptive or similar rights. There are no claims for finder’s fees or brokerage commission or other like payments in connection with this Agreement or the transactions contemplated

of the Issuer, or (iii) options or other rights to acquire from the Issuer any equity securities or securities convertible into or exchangeable for equity securities of the Issuer except as contemplated by the Transaction Agreements or as

 3.1.6 Except as expressly disclosed in a Schedule 13D or Schedule 13G (or amendments
thereto) filed by Holder with the SEC with respect to the beneficial ownership of the Issuer’s Common Stock, Holder is not currently (and at all times through Closing will refrain from being or becoming) a member of a “group” (within
the meaning of Section 13(d)(3) or Section 14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or any successor provision), including any group acting for the purpose of acquiring, holding or
disposing of equity securities of the Issuer (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) (but in any event without restriction on Sponsor’s ability to enter into the Investor Rights
Agreement or perform its obligations or exercise its rights thereunder).

record ownership of Holder’s Covered Shares, the validity of this Agreement or the performance by Holder of its obligations under this Agreement.

Affiliates is party to any contract, agreement or arrangement to acquire any equity interests or other interests exercisable or convertible into any equity interests of any Competing Business; provided, that, for the purposes of this

the effect of changing or influencing the control of the Issuer, nor in connection with or as a participant in any transaction having such purpose or effect) of less than 2%, in the aggregate, of the outstanding shares or capital stock, as
applicable of any class of any corporation that is traded on a nationally recognized securities exchange or inter-dealer quotation system (or its equivalent in any foreign jurisdiction).

 3.2.3 The execution,
delivery and performance of this Agreement (including compliance by the BigBear Parties with all of the provisions hereof) and the consummation of the transactions contemplated herein will not (i) conflict with or result in a breach or
violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any other property or assets of any BigBear Party or any of its subsidiaries pursuant to
the terms of any material indenture, mortgage, deed of trust, loan agreement, lease, license or other material agreement or instrument to which such BigBear Party or any of its subsidiaries is a party or to which such BigBear Party’s other

any material respect. 
 4. Additional Covenants. 

4.1 Holder agrees that, during the Restricted Period, except as contemplated by the Merger Agreement and the Transactions, it shall not, and

encumber, assign or otherwise dispose of (including by gift, merger, tendering into any tender offer or exchange offer or otherwise) (collectively, a “Transfer”), or enter into any contract, option, derivative, hedging or other
agreement or arrangement or understanding (including any profit-sharing arrangement) with respect to, or consent to, a Transfer of, any or all of the Covered Shares or any interest in the Covered Shares; (ii) grant any proxies or powers of
attorney with respect to any or all of the Covered Shares (except in connection with voting by proxy at a meeting of stockholders of the Issuer as contemplated by Section 1 of this Agreement); or (iii) permit to exist any Lien with respect
to any or all of the Covered Shares other than those created by this Agreement; provided, that any Lien with respect to Covered Shares that would not prevent, impair or delay Holder’s ability to comply with the terms and conditions of
this Agreement shall be permitted and will not be deemed to violate the restrictions contained above. Notwithstanding the foregoing, this Section 4.1 shall also not prohibit a Transfer of Covered Shares by Holder to an
Affiliate of Holder; provided, that such Transfer shall be permitted only if, prior to or in connection with such Transfer, the transferee agrees in writing, reasonably satisfactory in form and substance to BigBear, to assume all of the
obligations of Holder hereunder and to be bound by the terms of this Agreement. Any transfer in violation of this Section 4.1 shall be null and void ab initio. 

  
 - 6 - 

 4.2 In the event of a share dividend or distribution, or any change in the Covered Shares by
reason of any share dividend or distribution, sub-division, recapitalization, combination, conversion, exchange of shares or the like, the term “Covered Shares” shall be deemed to refer to and
include the Covered Shares as well as all such share dividends and distributions and any securities into which or for which any or all of the Covered Shares may be changed or exchanged or which are received in such transaction. Holder agrees, while
this Agreement is in effect, to notify BigBear promptly in writing (including by e-mail) of the number of any additional Covered Shares acquired by Holder, if any, after the date hereof. 

4.3 Holder agrees, while this Agreement is in effect, not to take or agree or commit to take any action that would make any representation and
warranty of Holder contained in this Agreement inaccurate in any material respect or have the effect of preventing or disabling Holder from performing its obligations under this Agreement. 

4.4 Standstill Obligations. Holder covenants and agrees that, during the Restricted Period: 

4.4.1 Holder shall not take, nor shall any of its Affiliates or Representatives take, whether directly or indirectly, any action intended to
solicit, initiate or knowingly encourage, or any action to continue or engage in discussions or negotiations with, any Person (other than the BigBear Parties and/or any of their Affiliates or Representatives), concerning, relating to or which is
intended or is reasonably likely to give rise to or result in, a Business Combination Proposal in respect of the Issuer other than with the BigBear Parties and their respective Affiliates and Representatives. If Holder or any of its Affiliates or
Representatives receives any inquiry or proposal regarding a Business Combination Proposal in respect of the Issuer, then Holder shall promptly notify such Person indicating only that it is subject to an exclusivity agreement that prohibits it from
considering such inquiry or proposal and, in such event, Holder shall also promptly notify BigBear of such facts and circumstances (provided that Sponsor shall not be obligated to provide such notice in violation of any obligation of confidentiality
owed to any third party as of the date hereof or any Law). Holder shall, and shall cause its Affiliates and Representatives to, immediately cease any and all existing discussions or negotiations with any Person (other than the BigBear Parties and/or
any of their Affiliates or Representatives) conducted prior to the date hereof with respect to, or which is reasonably likely to give rise to or result in, a Business Combination Proposal in respect of the Issuer. 

4.4.2 Holder shall not, nor shall Holder act in concert with any Person (other than the BigBear Parties and their Affiliates and
Representatives or as otherwise contemplated by this Agreement, the Investor Rights Agreement or the Merger Agreement) to make, or in any manner participate in, directly or indirectly, a “solicitation” of “proxies” or consents
(as such terms are used in the proxy solicitation rules of the SEC) or powers of attorney or similar rights to vote, or seek to advise or influence any person with respect to the voting of, any Covered Shares in connection with any vote or other
action with respect to the Acquiror Stockholder Matters, other than to recommend that stockholders of the Issuer vote in favor of approval of the Merger Agreement and the other Acquiror Stockholder Matters (and otherwise as expressly provided by
Section 1). 
 4.4.3 Holder shall not, nor shall Holder act in concert with any person to, deposit following the
execution and delivery of this Agreement any of the Covered Shares in a voting trust or subject any of the Covered Shares to any arrangement or agreement with any person with respect to the voting of the Covered Shares, except as provided by
Section 1.

 4.5 Stop Transfers. Holder agrees with, and covenants to, the BigBear Parties that
Holder shall not request that the Issuer register the transfer (book-entry or otherwise) of any certificate or uncertificated interest representing any Covered Shares during the term of this Agreement without the prior written consent of BigBear, in
its sole discretion, other than pursuant to a transfer permitted by Section 4.1. Holder hereby authorizes and instructs Issuer to instruct Issuer’s transfer agent to enter a stop transfer order with respect to all of
the Covered Shares subject to the provisions of this Agreement; provided, that any such stop transfer order will immediately be withdrawn and terminated by Issuer following termination of this Agreement. 

4.6 No Inconsistent Agreements. Holder hereby covenants and agrees that, except for this Agreement, Holder shall not, at any time while
this Agreement remains in effect, (i) enter into any voting agreement or voting trust with respect to Holder’s Covered Shares inconsistent with Holder’s obligations pursuant to this Agreement, (ii) grant a proxy, a consent or
power of attorney with respect to Holder’s Covered Shares (except in connection with voting by proxy at a meeting of stockholders of the Issuer as contemplated by Section 1 of this Agreement) or (iii) enter into any agreement or taken
any action that would make any representation or warranty of Holder contained herein untrue or incorrect in any material respect or have the effect of preventing Holder from performing any of its obligations under this Agreement. 

4.7 Non-Circumvention. Each party hereto agrees that it shall not, and shall cause its
Affiliates not to, indirectly accomplish that which it is not expressly permitted to accomplish directly under this Agreement pursuant to provisions of this Agreement that have not been terminated pursuant to Section 5.

 5. Termination. This Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of
the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earlier to occur of (i) the First Effective Time, (ii) such date and time as the Merger Agreement is validly
terminated in accordance with its terms and (iii) upon the mutual written agreement of each of the parties hereto to terminate this Agreement; provided, that nothing herein will relieve any party from liability for any willful and
material breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from such breach. Notwithstanding anything to the contrary herein, the
provisions of this Section 5 and Sections 6 and 7 shall survive the termination of this Agreement. 

6. No Recourse. Notwithstanding anything to the contrary contained herein or otherwise, but without limiting any provision in the Merger
Agreement or any other Transaction Agreement, this Agreement may only be enforced against, and any claims or causes of action that may be based upon, arise out of or relate to this Agreement, or the negotiation, execution or performance of this
Agreement or the transactions contemplated hereby, may only be made against the entities and Persons that are expressly identified as parties to this Agreement in their capacities as such and no former, current or future shareholders or
stockholders, equity holders, controlling persons, directors, officers, employees, general or limited partners, members, managers, agents or affiliates of any party hereto, or any former, current or future direct or indirect shareholder or
stockholder, equity holder, controlling person, director, officer, employee, general or limited partner, member, manager, agent or affiliate of any of the foregoing (each, a “Non-Recourse
Party”) shall have any liability for any obligations or liabilities of the parties to this Agreement or for any claim (whether in tort, contract or otherwise) based on, in respect of, or by reason of, the

  
 - 8 - 

 
transactions contemplated hereby or in respect of any oral representations made or alleged to be made in connection herewith. Without limiting the rights of any party against the other parties
hereto, in no event shall any party or any of its affiliates seek to enforce this Agreement against, make any claims for breach of this Agreement against, or seek to recover monetary damages from, any
Non-Recourse Party.

7.4 Modifications and Amendments. This Agreement may not be amended, modified, supplemented or waived except by an instrument in

7.5 Assignment. Except for transfers permitted by Section 4.1, neither this Agreement nor any rights,
interests or obligations that may accrue to the parties hereunder may be transferred or assigned without the prior written consent of each of the other parties hereto. 

7.6 Benefit. 
 7.6.1
Except as otherwise provided herein, this Agreement shall be binding upon, and inure to the benefit of the parties hereto and their heirs, executors, administrators, successors, legal representatives, and permitted assigns, and the agreements,
representations, warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such heirs, executors, administrators, successors, legal representatives and permitted assigns. This Agreement shall not
confer rights or remedies upon any person other than the parties hereto and their respective successors and assigns.

 7.7 Governing Law. This Agreement, and all claims or causes of action based upon,
arising out of, or related to this Agreement or the transactions contemplated hereby, shall be governed by, and construed in accordance with, the Laws of the State of Delaware, without giving effect to principles or rules of conflict of laws to the
extent such principles or rules would require or permit the application of Laws of another jurisdiction. 
 7.8 Consent to
Jurisdiction; Waiver of Jury Trial. The parties hereto hereby agree and consent to be subject to the exclusive jurisdiction of the Court of Chancery of the State of Delaware or, to the extent such court declines jurisdiction, first to any
federal court, or second, to any state court, each located in Wilmington, Delaware, to the exclusion of other courts, and hereby waive the right to assert the lack of personal or subject matter jurisdiction or improper venue in connection with any
such suit, action or other proceeding. In furtherance of the foregoing, each of the parties hereto (a) waives the defense of inconvenient forum, (b) agrees not to commence any suit, action or other proceeding arising out of this
Agreement or any transactions contemplated hereby other than in any such court, and (c) agrees that a final judgment in any such suit, action or other proceeding shall be conclusive and may be enforced in other jurisdictions by suit or judgment
or in any other manner provided by Law. Nothing herein contained shall be deemed to affect the right of any Party to serve process in any manner permitted by Law or to commence legal proceedings or otherwise proceed against any other party in any
other jurisdiction, in each case, to enforce judgments obtained in any Action brought pursuant to this Section 7.8. EACH OF THE PARTIES HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION BASED UPON,
ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. Without limiting the foregoing, each party hereto hereby agrees that service of process upon such party in any action or proceeding contemplated by this
Section 7.8 shall be effective if notice is given in accordance with Section 7.2. 
 7.9
Severability. If any provision of this Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Agreement shall not in any way be affected or impaired thereby and shall
continue in full force and effect. 
 7.10 No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in
exercising any right, power or remedy under this Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or remedy
under this Agreement by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or
remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Agreement shall entitle
the party receiving such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances
without such notice or demand.

 7.11 Remedies. 

7.11.1 The parties agree that Holdings and BigBear would suffer irreparable damage if this Agreement was not performed or the Closing is not
consummated in accordance with its specific terms or was otherwise breached and that money damages or other legal remedies would not be an adequate remedy for any such damage. It is accordingly agreed that Holdings and BigBear shall be entitled to
equitable relief, including in the form of an injunction or injunctions, to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, including Holder’s obligations to vote
its Covered Shares as provided in this Agreement, without proof of actual damages or the inadequacy of monetary damages as a remedy, in an appropriate court of competent jurisdiction as set forth in Section 7.8, this being
in addition to any other remedy to which any party is entitled at law or in equity, including money damages. The right to specific enforcement shall include the right of Holdings or BigBear to cause Holder to cause the transactions contemplated
hereby to be consummated on the terms and subject to the conditions and limitations set forth in this Agreement. The parties hereto further agree (i) to waive any requirement for the security or posting of any bond in connection with any such
equitable remedy, (ii) not to assert that a remedy of specific enforcement pursuant to this Section 7.11 is unenforceable, invalid, contrary to applicable law or inequitable for any reason and (iii) to waive any
defenses in any action for specific performance, including the defense that a remedy at law would be adequate.
 7.11.2 The parties
acknowledge and agree that this Section 7.11 is an integral part of the transactions contemplated hereby and without that right, the parties hereto would not have entered into this Agreement. 

7.11.3 In any dispute arising out of or related to this Agreement, or any other agreement, document, instrument or certificate contemplated
hereby, or any transactions contemplated hereby or thereby, the applicable adjudicating body shall award to the prevailing party, if any, the costs and attorneys’ fees reasonably incurred by the prevailing party in connection with the dispute
and the enforcement of its rights under this Agreement or any other agreement, document, instrument or certificate contemplated hereby and, if the adjudicating body determines a party to be the prevailing party under circumstances where the
prevailing party won on some but not all of the claims and counterclaims, the adjudicating body may award the prevailing party an appropriate percentage of the costs and attorneys’ fees reasonably incurred by the prevailing party in connection
with the adjudication and the enforcement of its rights under this Agreement or any other agreement, document, instrument or certificate contemplated hereby or thereby. 

7.12 Survival of Representations and Warranties. None of the representations and warranties made by the parties hereto in this Agreement
shall survive the Closing. 
 7.13 No Broker or Finder. Holder represents and warrants to the BigBear Parties that no broker, finder
or other financial consultant has acted on its behalf in connection with this Agreement or the transactions contemplated hereby in such a way as to create any liability on a BigBear Party. Holder agrees to indemnify and save each BigBear Party
harmless from any claim or demand for commission or other compensation by any broker, finder, financial consultant or similar agent claiming to have been employed by or on behalf of a BigBear Party and to bear the cost of legal expenses incurred in
defending against any such claim. 

  
 - 12 - 

 7.14 Headings and Captions. The headings and captions of the various subdivisions of
this Agreement are for convenience of reference only and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof. 

7.15 Counterparts. This Agreement may be executed in one or more counterparts, all of which when taken together shall be considered one
and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other parties, it being understood that the parties need not sign the same counterpart. In the event that any signature is
delivered any form of electronic delivery, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such signature page were an original
thereof. 
 7.16 Construction. The words “include,” “includes,” and “including”
will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and
vice versa, unless the context otherwise requires. The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this
Agreement as a whole and not to any particular subdivision unless expressly so limited. The word “or” shall be disjunctive but not exclusive. The parties hereto intend that each representation, warranty, and covenant contained
herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same
subject matter (regardless of the relative levels of specificity) which such party has not breached will not detract from or mitigate the fact that such party is in breach of the first representation, warranty, or covenant. 

7.17 Mutual Drafting. This Agreement is the joint product of the parties hereto and each provision hereof has been subject to the mutual
consultation, negotiation and agreement of the parties hereto and shall not be construed for or against any party. 
 7.18 Consent to
Disclosure. Holder hereby consents to the publication and disclosure in the Proxy Statement (and, as and to the extent otherwise required by the federal securities laws or the SEC or any other securities authorities, any other documents or
communications provided or filed by the Issuer, Holdings or BigBear to or with any Governmental Authority or to securityholders of the Issuer) of Holder’s identity and beneficial ownership of Covered Shares and the nature of Holder’s
commitments, arrangements and understandings under and relating to this Agreement and, if deemed appropriate by the Issuer, Holdings or BigBear, a copy of this Agreement. Holder will promptly provide any information reasonably requested by the
Issuer, Holdings or BigBear for any regulatory application or filing made or approval sought in connection with the Transactions (including filings with the SEC). 

7.19 No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in any BigBear Party any direct or indirect
ownership or incidence of ownership of or with respect to any Covered Shares. 

  
 - 13 - 

 7.20 Certificates. Promptly following the date of this Agreement, Holder shall advise
the Issuer’s transfer agent in writing that Holder’s Covered Shares are subject to the restrictions set forth herein and, in connection herewith, provide the Issuer’s transfer agent in writing with such information as is reasonable to
ensure compliance with such restrictions. 
 7.21 No Partnership, Agency or Joint Venture. This Agreement is intended to create a
contractual relationship among Holder and the BigBear Parties, and is not intended to create, and does not create, any agency, partnership, joint venture or any like relationship between or among the parties.
