Exhibit 4.5

DESCRIPTION OF THE REGISTRANT’S SECURITIES

REGISTERED PURSUANT TO SECTION 12 OF THE 

SECURITIES EXCHANGE ACT OF 1934

 

The summary of the general terms
and provisions of the registered securities of NextNav Inc. (“NextNav,” the “Company,” “us,” “we,”
or “our”) set forth below does not purport to be complete and is subject to and qualified in its entirety by reference to
our amended and restated certificate of incorporation (our “charter”) and our bylaws (our “bylaws”), each of which
is incorporated by reference as an exhibit to this Annual Report on Form 10-K filed with the Securities and Exchange Commission, of which
this Exhibit 4.5 is a part. We encourage you to read our charter and bylaws and the applicable provisions of the General Corporation
Law of the State of Delaware (the “DGCL”) for additional information.

 

As of December 31, 2021, our authorized
capital stock consisted of 500,000,000 shares of common stock, par value $0.0001 per share (“Common Stock”), and 100,000,000
shares of undesignated preferred stock, par value $0.0001 per share (the “preferred stock”).

 

Common Stock

 

Dividend Rights

 

Subject to preferences that may
apply to shares of preferred stock outstanding at the time, holders of outstanding shares of Common Stock are entitled to receive dividends
and other distributions (payable in cash, property or our capital stock) when, as and if declared thereon by our board of directors (the
“Board”) from time to time out of any assets or funds legally available therefore and shall share equally on a per share basis
in such dividends and distributions.

 

Voting Rights

 

Except as otherwise required by
law or our charter (including any preferred stock designation), (i) the holders of Common Stock possess all voting power with respect
to the Company and (ii) each outstanding share of Common Stock entitles the holder to one vote on any matter properly submitted to the
stockholders.

 

Preemptive Rights

 

Holders of outstanding shares
of our Common Stock are not entitled to preemptive or other similar subscription rights to purchase any of our securities.

 

Conversion or Redemption Rights

 

Our Common Stock is neither convertible
nor redeemable.

 

Liquidation Rights

 

Subject to applicable law and
the rights, if any, of the holders of any outstanding series of the preferred stock upon our liquidation, the holders of our Common Stock
shall be entitled to receive all of our remaining assets available for distribution to our stockholders, ratably in proportion to the
number of shares of our Common Stock held by each stockholder.

 

Preferred Stock

 

Our Board may, without further
action by our stockholders, from time to time, direct the issuance of up to 100,000,000 shares of preferred stock in one or more series
and may, at the time of issuance, fix the voting powers, if any, and determine the designations, powers, preferences, and relative, participating,
optional, special and other rights, if any, of each such series and any qualifications, limitations and restrictions thereof. Accordingly,
our Board, without stockholder approval, may issue preferred stock with voting, conversion, or other rights that could adversely affect
the voting power and other rights of the holders of our Common Stock. Preferred stock could be issued quickly with terms calculated to
delay or prevent a change of control or make removal of management more difficult. Additionally, the issuance of preferred stock may have
the effect of decreasing the market price of our Common Stock, may adversely affect the voting and other rights of the holders of our
Common Stock, and could have the effect of delaying, deferring or preventing a change of control of us or other corporate action.

 

     

     

    

 

Warrants

 

As of March 18, 2022, we have
registered warrants outstanding exercisable, at a price per share of $11.50, for a total of 18,750,000 shares of our Common Stock: (a)
10,000,000 of such warrants were issued in registered form under a warrant agreement between Continental Stock Transfer & Trust
Company, as warrant agent, and us (the “public warrants”), and (b) 8,750,000 of such warrants were issued in a private placement
transaction. The warrant agreement provides that the terms of the public warrants may be amended without the consent of any holder to
cure any ambiguity or correct any defective provision, but requires the approval by the holders of at least the majority of the then outstanding
public warrants to make any change that adversely affects the interests of the registered holders of such public warrants.. The warrants
expire on October 28, 2026 (five years after completion of the previously disclosed business combination consummated on October
28, 2021), at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

 

We are not obligated to deliver
any shares of our Common Stock pursuant to the exercise for cash of a warrant, and have no obligation to settle such warrant exercise
unless a registration statement under the Securities Act of 1933, as amended (the “Securities Act”), with respect to the shares
of our Common Stock underlying the warrants is then effective and a prospectus relating thereto is current. No warrant will be exercisable
and we will not be obligated to issue shares of our Common Stock upon exercise of a warrant unless our Common Stock issuable upon such
warrant exercise has been registered, qualified or deemed to be exempt from the registration or qualifications requirements of the securities
laws of the state of residence of the registered holder of the warrants.

 

We may call the warrants for redemption:

 

		●	in whole and not in part;

 

		●	at a price of $0.01 per warrant;

 

		●	upon not less than 30 days’ prior written notice
of redemption to each warrant holder; and

 

		●	if, and only if, the reported last sale price of our Common
Stock (or the closing bid price of our Common Stock in the event shares of our Common Stock are not traded on any specific day)
equals or exceeds $18.00 per share for any 20 trading days within a 30 trading day period ending three trading days before
we send the notice of redemption to the warrant holders.

 

If and when the warrants become
redeemable by the Company, we may exercise our redemption right even if we are unable to register or qualify the underlying securities
for sale under all applicable state securities laws.

 

We have established the last of
the redemption criterion discussed above to prevent a redemption call unless there is at the time of the call a significant premium to
the warrant exercise price. If the foregoing conditions are satisfied and we issue a notice of redemption of the warrants, each warrant
holder will be entitled to exercise its warrant prior to the scheduled redemption date. However, the price of our Common Stock may fall
below the $18.00 redemption trigger price as well as the $11.50 (for whole shares) warrant exercise price after the redemption notice
is issued.

 

If we call the warrants for redemption
as described above, our management will have the option to require any holder that wishes to exercise its warrant to do so on a “cashless
basis.” In determining whether to require all holders to exercise their warrants on a “cashless basis,” our management
will consider, among other factors, our cash position, the number of warrants that are outstanding and the dilutive effect on our securityholders
of issuing the maximum number of shares of our Common Stock issuable upon the exercise of the warrants. If our management takes advantage
of this option, all holders of warrants would pay the exercise price by surrendering their warrants for that number of shares of our Common
Stock equal to the quotient obtained by dividing (x) the product of the number of shares of our Common Stock underlying the warrants,
multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the
fair market value. The “fair market value” shall mean the average reported last sale price of our Common Stock for the 10 trading
days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants.

 

    2

     

    

 

If our management takes advantage
of this option, the notice of redemption will contain the information necessary to calculate the number of shares of our Common Stock
to be received upon exercise of the warrants, including the “fair market value” in such case. Requiring a cashless exercise
in this manner will reduce the number of shares to be issued and thereby lessen the dilutive effect of a warrant redemption. If we call
the warrants for redemption and our management does not take advantage of this option, Spartacus Acquisition Corporation’s sponsor
and its permitted transferees would still be entitled to exercise its warrants for cash or on a cashless basis using the same formula
described above that other warrant holders would have been required to use had all warrant holders been required to exercise their warrants
on a cashless basis, as described in more detail below.

 

A holder of a warrant may notify
us in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise such warrant,
to the extent that after giving effect to such exercise, such person (together with such person’s affiliates), to the warrant agent’s
actual knowledge, would beneficially own in excess of 9.8% (or such other amount as a holder may specify) of the shares of our Common
Stock outstanding immediately after giving effect to such exercise.

 

If the number of outstanding shares
of our Common Stock is increased by a stock dividend payable in shares of our Common Stock, or by a split-up of shares of our Common
Stock or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares
of our Common Stock issuable on exercise of each warrant will be increased in proportion to such increase in the outstanding shares of
our Common Stock. A rights offering to holders of our Common Stock entitling holders to purchase shares of our Common Stock at a price
less than the fair market value will be deemed a stock dividend of a number of shares of our Common Stock equal to the product of (i) the
number of shares of our Common Stock actually sold in such rights offering (or issuable under any other equity securities sold in such
rights offering that are convertible into or exercisable for our Common Stock) multiplied by (ii) one (1) minus the quotient
of (x) the price per share of our Common Stock paid in such rights offering divided by (y) the fair market value. For these
purposes (i) if the rights offering is for securities convertible into or exercisable for our Common Stock, in determining the price
payable for our Common Stock, there will be taken into account any consideration received for such rights, as well as any additional amount
payable upon exercise or conversion and (ii) fair market value means the volume weighted average price of our Common Stock as reported
during the 10 trading day period ending on the trading day prior to the first date on which the shares of our Common Stock trade
on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

 

In addition, if we, at any time
while the warrants are outstanding and unexpired, pay a dividend or make a distribution in cash, securities or other assets to the holders
of our Common Stock on account of such shares of our Common Stock (or other shares of our capital stock into which the warrants are convertible),
other than (a) as described above or (b) certain ordinary cash dividends, then the warrant exercise price will be decreased,
effective immediately after the effective date of such event, by the amount of cash and/or the fair market value of any securities or
other assets paid on each share of Common Stock in respect of such event.

 

If the number of outstanding shares
of our Common Stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of our Common Stock
or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar
event, the number of shares of our Common Stock issuable on exercise of each warrant will be decreased in proportion to such decrease
in outstanding shares of our Common Stock.

 

Whenever the number of shares
of our Common Stock purchasable upon the exercise of the warrants is adjusted, as described above, the warrant exercise price will be
adjusted by multiplying the warrant exercise price immediately prior to such adjustment by a fraction (x) the numerator of which
will be the number of shares of our Common Stock purchasable upon the exercise of the warrants immediately prior to such adjustment, and
(y) the denominator of which will be the number of shares of our Common Stock so purchasable immediately thereafter.

 

    3

     

    

 

In case of any reclassification
or reorganization of the outstanding shares of our Common Stock (other than those described above or that solely affects the par value
of such shares of our Common Stock), or in the case of any merger or consolidation of us with or into another corporation (other than
a consolidation or merger in which we are the continuing corporation and that does not result in any reclassification or reorganization
of our outstanding shares of Common Stock), or in the case of any sale or conveyance to another corporation or entity of the assets or
other property of us as an entirety or substantially as an entirety in connection with which we are dissolved, the holders of the warrants
will thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the warrants and
in lieu of the shares of our Common Stock immediately theretofore purchasable and receivable upon the exercise of the rights represented
thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification,
reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the warrants would
have received if such holder had exercised their warrants immediately prior to such event. If less than 70% of the consideration receivable
by the holders of our Common Stock in such a transaction is payable in the form of our Common Stock in the successor entity that is listed
for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading
or quoted immediately following such event, and if the registered holder of the warrant properly exercises the warrant within thirty days
following public disclosure of such transaction, the warrant exercise price will be reduced as specified in the warrant agreement based
on the Black-Scholes value (as defined in the warrant agreement) of the warrant.

 

The warrants may be exercised
upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form
on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price
(or on a cashless basis, if applicable), by certified or official bank check payable to us, for the number of warrants being exercised.
The warrant holders will not have the rights or privileges of holders of our Common Stock and any voting rights until they exercise their
warrants and receive shares of our Common Stock. After the issuance of shares of our Common Stock upon exercise of the warrants, each
holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

 

Warrants may be exercised only
for a whole number of shares of our Common Stock. No fractional shares will be issued upon exercise of the warrants. If, upon exercise
of the warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round down to the nearest
whole number of shares of our Common Stock to be issued to the warrant holder.

 

We have agreed that, subject to
applicable law, any action, proceeding or claim against us arising out of or relating in any way to the warrant agreement will be brought
and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York,
and we irrevocably submit to such jurisdiction, which jurisdiction will be the exclusive forum for any such action, proceeding or claim.
This provision applies to claims under the Securities Act but does not apply to claims under the Securities Exchange Act of 1934, as amended
(the “Exchange Act”), or any claim for which the federal district courts of the United States of America are the
sole and exclusive forum.

 

Anti-Takeover Effects of our Charter and Bylaws

 

Our charter, bylaws and the DGCL
contain provisions, which are summarized in the following paragraphs, that are intended to enhance the likelihood of continuity and stability
in the composition of our Board. These provisions are intended to avoid costly takeover battles, reduce our vulnerability to a hostile
change of control and enhance the ability of our Board to maximize stockholder value in connection with any unsolicited offer to acquire
us. However, these provisions may have an anti-takeover effect and may delay, deter or prevent a merger or acquisition of us by means
of a tender offer, a proxy contest or other takeover attempt that a stockholder might consider in its best interest, including those attempts
that might result in a premium over the prevailing market price for the shares of our Common Stock held by stockholders.

 

These provisions include:

 

Special Meetings of Stockholders

 

Our charter and bylaws provide
that, subject to applicable law and the rights, if any, of the holders of any outstanding series of the preferred stock, special meetings
of our stockholders may be called only by the chairman of our Board, our chief executive officer, or our Board pursuant to a resolution
adopted by a majority of the Board. Our bylaws also prohibit the conduct of any business at a special meeting other than as specified
in the notice for such meeting. These provisions may have the effect of deferring, delaying or discouraging hostile takeovers, or changes
in control or management of the Company.

 

    4

     

    

 

Advance Notice Procedures

 

Our bylaws establish an advance
notice procedure for stockholders’ proposals to be brought before an annual meeting, including proposed nominations of persons for
election to our Board. Stockholders at an annual meeting will only be able to consider proposals or nominations specified in the notice
of meeting or brought before the meeting by or at the direction of our Board or by a stockholder who was a stockholder of record entitled
to vote at such annual meeting on the date of the giving of the notice and on the record date for the meeting, who has given our Secretary
timely written notice, in proper form, of the stockholder’s intention to bring that business before the meeting. Additionally, our
bylaws provide that if the stockholder does not appear at the annual meeting of stockholders to present the proposed business, such proposed
business shall not be transacted, notwithstanding that proxies in respect of such matter may have been received by us. Although our bylaws
will not give our Board the power to approve or disapprove stockholder nominations of candidates or proposals regarding other business
to be conducted at a special or annual meeting, the bylaws may have the effect of precluding the conduct of certain business at a meeting
if the proper procedures are not followed or may discourage or deter a potential acquirer from conducting a solicitation of proxies to
elect its own slate of directors or otherwise attempting to obtain control of us.

 

Removal of Directors; Vacancies

 

Our charter and bylaws provide
that, subject to the rights of any holders of any class or series of capital stock then outstanding, any or all of the directors may be
removed from office, with or without cause, by the affirmative vote of holders of at least two-thirds (2/3) of the voting power of all
then outstanding shares of capital stock entitled to vote generally in the election of directors, voting together as a single class.

 

In addition, our bylaws provide
that, subject to the rights granted to one or more series of preferred stock then outstanding, any newly created directorship on our Board
that results from an increase in the number of directors and any vacancies on our Board resulting from death, resignation, retirement,
disqualification, removal or other cause may be filled solely and exclusively by a majority vote of the remaining directors then in office,
even if less than a quorum, by a sole remaining director (and not by stockholders).

 

Supermajority Approval Requirements

 

Our charter and bylaws provide
that our Board is expressly authorized to adopt, amend, alter or repeal our bylaws without any action on the part of the stockholders,
subject to limited exceptions. The affirmative vote of a majority of the Board shall be required to adopt, amend, alter or repeal the
bylaws. The bylaws also may be adopted, amended, altered or repealed by the affirmative vote of the holders of at least two-thirds (2/3)
of the voting power of all of the then-outstanding shares entitled to vote on the election of directors, in addition to any vote of the
holders of any class or series of capital stock required by law (or any preferred stock designation).

 

The DGCL provides generally that
the affirmative vote of a majority of the outstanding shares entitled to vote thereon, voting together as a single class, is required
to amend a corporation’s certificate of incorporation, unless the certificate of incorporation requires a greater percentage.

 

Our charter provides that, in
addition to any vote of the holders of any class or series of our stock required by law or by the charter, the affirmative vote of the
holders of at least two-thirds (2/3) of the voting power of all of the then-outstanding shares entitled to vote generally in the
election of directors, voting together as a single class, shall be required to amend Article V (Board of Directors), Article VI
(Bylaws), Article VII (Special Meeting of Stockholders; Action by Written Consent), Article VIII (Limited Liability; Indemnification),
Article IX (Amendment of the Amended and Restated Certificate of Incorporation) or Article X (Exclusive Forum from Certain Lawsuits;
Consent to Jurisdiction) of the charter; provided, that if two-thirds (2/3) of the Board has approved such amendment or repeal
or adoption, then only the affirmative vote of the holders of at least a majority of the voting power of all of the then-outstanding shares
entitled to vote generally in the election of directors shall be required to amend or repeal, or adopt any provision inconsistent with,
the Articles listed in this sentence.

 

Authorized but Unissued Shares

 

Delaware law does not require
stockholder approval for any issuance of authorized shares. However, the listing requirements of Nasdaq, which would apply if and so long
as our Common Stock is listed on Nasdaq, require stockholder approval of certain issuances equal to or exceeding 20% of the then outstanding
voting power or then outstanding number of shares of our Common Stock. Additional shares that may be issued in the future may be used
for a variety of corporate purposes, including future public offerings, to raise additional capital, to facilitate acquisitions and for
employee benefit plans.

 

    5

     

    

 

One of the effects of the existence
of unissued and unreserved Common Stock may be to enable our Board to issue shares to persons friendly to current management, which issuance
could render more difficult or discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise,
and thereby protect the continuity of management and possibly deprive stockholders of opportunities to sell their shares at prices higher
than prevailing market prices.

 

Business Combinations

 

We are and will continue to be
subject to the provisions of Section 203 of the DGCL. In general, Section 203 prohibits a publicly held Delaware corporation
from engaging in a “business combination” with an “interested stockholder” for a three-year period following the
time that the person becomes an interested stockholder, unless the business combination is approved in a prescribed manner. A “business
combination” includes, among other things, a merger, asset or stock sale or other transaction resulting in a financial benefit to
the interested stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns, or
did own within three years prior to the determination of interested stockholder status, 15% or more of the corporation’s voting
stock.

 

Under Section 203, a business
combination between a corporation and an interested stockholder is prohibited unless it satisfies one of the following conditions: (1) before
the stockholder became an interested stockholder, the board of directors approved either the business combination or the transaction which
resulted in the stockholder becoming an interested stockholder; (2) upon consummation of the transaction which resulted in the stockholder
becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at
the time the transaction commenced, excluding for purposes of determining the voting stock outstanding, shares owned by persons who are
directors and also officers, and certain employee stock plan; or (3) at or after the time the stockholder became and interested stockholder,
the business combination was approved by the board of directors and authorized at an annual or special meeting of the stockholders by
the affirmative vote of at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder.

 

Under certain circumstances, Section 203
of the DGCL will make it more difficult for a person who would be an “interested stockholder” to effect various business combinations
with us for a three-year period. This provision may encourage companies interested in acquiring us to negotiate in advance with our Board
because the stockholder approval requirement would be avoided if our Board approves either the business combination or the transaction
which results in the stockholder becoming an interested stockholder. These provisions also may have the effect of preventing changes in
our Board and may make it more difficult to accomplish transactions which stockholders may otherwise deem to be in their best interests.

 

Dissenters’ Rights of Appraisal and Payment

 

Under the DGCL, with certain exceptions,
our stockholders will have appraisal rights in connection with a merger or consolidation of us. Pursuant to the DGCL, stockholders who
properly request and perfect appraisal rights in connection with such merger or consolidation will have the right to receive payment of
the fair value of their shares as determined by the Delaware Court of Chancery.

 

Stockholders’ Derivative Actions

 

Under the DGCL, any of our stockholders
may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the stockholders
bringing the action is a holder of our shares at the time of the transaction to which the action relates or such stockholders’ stock
thereafter devolved by operation of law.

 

    6

     

    

 

Exclusive Forum

 

Our charter provides that, unless
the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the sole
and exclusive forum for (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a claim of breach
of a fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (3) any action asserting
a claim against us or any director, officers or employees arising pursuant to any provision of the DGCL, our charter, or our bylaws or
(4) any action asserting a claim against us, our directors, officers or employees that is governed by the internal affairs doctrine
and, if brought outside of Delaware, the stockholder bringing the suit will be deemed to have consented to service of process on such
stockholder’s counsel, except for, as to each of (1) though (4) above, any action (A) as to which the Court of Chancery
in the State of Delaware determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and
the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten days following such determination),
(B) which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, or (C) for which the
Court of Chancery does not have subject matter jurisdiction. Notwithstanding the foregoing, (i) the exclusive forum provisions will
not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim for which the federal
courts have exclusive jurisdiction and (ii) unless we consent in writing to the selection of an alternative forum, the federal district
courts of the United States of America shall, to the fullest extent permitted by law, be the exclusive forum for the resolution of
any complaint asserting a cause of action arising under the Securities Act or the rules and regulations promulgated thereunder. Although
we believe these provisions benefit us by providing increased consistency in the application of Delaware law for the specified types of
actions and proceedings, the provisions may have the effect of discouraging lawsuits against us or our directors and officers.

 

Limitations on Liability and Indemnification of
Officers and Directors

 

The DGCL authorizes corporations
to limit or eliminate the personal liability of directors to corporations and their stockholders for monetary damages for breaches of
directors’ fiduciary duties, subject to certain exceptions. Our charter includes a provision that eliminates the personal liability
of directors for monetary damages for any breach of fiduciary duty as a director, except to the extent such exemption from liability or
limitation thereof is not permitted under the DGCL. The effect of these provisions will be to eliminate the rights of us and our
stockholders, through stockholders’ derivative suits on our behalf, to recover monetary damages from a director for breach of fiduciary
duty as a director, including breaches resulting from grossly negligent behavior. However, exculpation will not apply to any director
if the director has acted in bad faith, knowingly or intentionally violated the law, authorized illegal dividends or redemptions or derived
an improper benefit from his or her actions as a director.

 

Our bylaws provide that we must
indemnify and advance expenses to our directors and officers to the fullest extent authorized by the DGCL and our charter and we have
entered into indemnification agreements with each of our officers and directors, which require us to indemnify our directors and officers
for expenses (including, without limitation, attorneys’ fees, judgments, fines, ERISA excise taxes and penalties and amounts paid
in settlement) in any action or proceeding arising out of their services as one of our directors or officers or as a director or officer
of any other company or enterprise to which the person provides services at our request. We also are expressly authorized to carry directors’
and officers’ liability insurance providing indemnification for our directors, officers and certain employees for some liabilities.
We believe that these indemnification and advancement provisions and insurance will be useful to attract and retain qualified directors
and officers.

 

The limitation of liability, indemnification
and advancement provisions included in our charter and bylaws and the indemnification agreements may discourage stockholders from bringing
a lawsuit against directors for breaches of their fiduciary duty. These provisions also may have the effect of reducing the likelihood
of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our
stockholders. In addition, your investment may be adversely affected to the extent we pay the costs of settlement and damage awards against
directors and officers pursuant to these indemnification provisions.

 

There is currently no pending
material litigation or proceeding involving any of our directors, officers or employees for which indemnification is sought.

ARTICLE II

REGISTRATIONS

 

2.1 Shelf
Registration.

 

2.1.1 Filing.
The Company shall file, as soon as practicable, but in any event within sixty (60) days after the Closing Date (the “Filing
Deadline”), a Registration Statement for a Shelf Registration on Form S-1 (the “Form S-1 Shelf”)
or, if the Company is eligible to use a Form S-3 Shelf, a Registration Statement for a Shelf Registration on Form S-3 (the “Form
S-3 Shelf”), in each case, covering the resale of all the Registrable Securities (determined as of two business days prior
to such filing) on a delayed or continuous basis. The Company shall use commercially reasonable efforts to cause such Shelf Registration
to be declared effective as soon as possible after filing, but in no event later than the earlier of (i) sixty (60) days following the
Filing Deadline and (ii) three (3) business days after the Commission notifies the Company that it will not review such Shelf Registration,
if applicable (the “Effectiveness Deadline”); provided, that, if such Shelf Registration filed pursuant to this
Section 2.1.1 is reviewed by, and the Company receives comments from, the Commission with respect to such Shelf Registration,
the Effectiveness Deadline shall be extended to ninety (90) days following the Filing Deadline. Such Shelf Registration shall provide
for the resale of the Registrable Securities included therein pursuant to any method or combination of methods legally available to, and
requested by, any Holder named therein (and the FF Beneficial Investor if the FF Investor submits such request). The Company shall maintain
a Shelf Registration in accordance with the terms hereof, and shall prepare and file with the Commission such amendments, including post-effective
amendments, and supplements as may be necessary to keep a Shelf Registration continuously effective, available for use and in compliance
with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. In the event the Company
files a Form S-1 Shelf, the Company shall use its commercially reasonable efforts to convert the Form S-1 Shelf (and any Subsequent Shelf
Registration) to a Form S-3 Shelf as soon as practicable after the Company is eligible to use Form S-3.

 

2.1.2 Subsequent
Shelf Registration. If any Shelf Registration ceases to be effective under the Securities Act for any reason at any time while Registrable
Securities are still outstanding, the Company shall, subject to Section 3.4, use its commercially reasonable efforts to promptly
cause such Shelf Registration to again become effective under the Securities Act (including obtaining the prompt withdrawal of any order
suspending the effectiveness of such Shelf Registration), and shall use its commercially reasonable efforts to promptly amend such Shelf
Registration in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Shelf Registration
or file an additional registration statement as a Shelf Registration (a “Subsequent Shelf Registration”) registering
the resale of all Registrable Securities (determined as of two business days prior to such filing), and pursuant to any method or combination
of methods legally available to, and requested by, any Holder named therein. If a Subsequent Shelf Registration is filed, the Company
shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration to become effective under the Securities
Act as promptly as is reasonably practicable after the filing thereof (it being agreed that the Subsequent Shelf Registration shall be
an automatic shelf registration statement (as defined in Rule 405 promulgated under the Securities Act) if the Company is a well-known
seasoned issuer (as defined in Rule 405 promulgated under the Securities Act) at the most recent applicable eligibility determination
date) and (ii) keep such Subsequent Shelf Registration continuously effective, available for use and in compliance with the provisions
of the Securities Act until such time as there are no longer any Registrable Securities. Any such Subsequent Shelf Registration shall
be on Form S-3 to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration shall be on
another appropriate form.

 

2.1.3 Requests
for Underwritten Shelf Takedowns. At any time and from time to time when an effective Shelf Registration is on file with the Commission,
and subject to the expiration of the Applicable Lock-Up Period, one or more of the Holders (such Holder or Holders being in such case,
“Demanding Holders”) may request to sell all or any portion of its Registrable Securities in an Underwritten
Offering that is registered pursuant to the Shelf Registration (each, an “Underwritten Shelf Takedown”); provided,
however, that the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include Registrable
Securities proposed to be sold by the Demanding Holders with a total offering price reasonably expected to exceed, in the aggregate, $50,000,000
(the “Minimum Takedown Threshold”). All requests for Underwritten Shelf Takedowns shall be made by giving written
notice to the Company, which shall specify the approximate number of Registrable Securities proposed to be sold by the Demanding Holders
in the Underwritten Shelf Takedown. Subject to Section 2.4.4, the Company shall have the right to select the Underwriters
for such offering (which shall consist of one or more reputable nationally recognized investment banks), subject to the initial Demanding
Holders’ prior approval (which shall not be unreasonably withheld, conditioned or delayed). The Holders may demand not more than
two (2) Underwritten Shelf Takedowns in any twelve (12) month period.

 

    6

    

    

 

2.1.4 Reduction
of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Shelf Takedown, in good faith, advises the
Company, the Demanding Holders and the Holders requesting piggy back rights pursuant to this Agreement with respect to such Underwritten
Shelf Takedown (the “Requesting Holders”) (if any) that the dollar amount or number of Registrable Securities
that the Demanding Holders and the Requesting Holders (if any) desire to sell, taken together with all other shares of Common Stock or
other equity securities that the Company desires to sell and all other shares of Common Stock or other equity securities, if any, that
have been requested to be sold in such Underwritten Offering pursuant to separate written contractual piggy-back registration rights held
by any other stockholders, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten
Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of
such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”),
then the Company shall include in such Underwritten Offering, before including any shares of Common Stock or other equity securities proposed
to be sold by Company or by other holders of Common Stock or other equity securities, the Registrable Securities of the Demanding Holders
and the Requesting Holders (if any) (pro rata based on the respective number of Registrable Securities that each Demanding Holder and
Requesting Holder (if any) has requested be included in such Underwritten Shelf Takedown and the aggregate number of Registrable Securities
that the Demanding Holders and Requesting Holders have requested be included in such Underwritten Shelf Takedown) that can be sold without
exceeding the Maximum Number of Securities.

 

2.1.5 Withdrawal.
Prior to the filing of the applicable “red herring” prospectus or prospectus supplement used for marketing such Underwritten
Shelf Takedown, a majority-in-interest of the Demanding Holders initiating an Underwritten Shelf Takedown shall have the right to withdraw
from such Underwritten Shelf Takedown for any or no reason whatsoever upon written notification (a “Withdrawal Notice”)
to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Shelf Takedown; provided that
the other Initial Investors or the other NextNav Investors may elect to have the Company continue an Underwritten Shelf Takedown if the
Minimum Takedown Threshold would still be satisfied by the Registrable Securities proposed to be sold in the Underwritten Shelf Takedown
by the other Initial Investors or the other NextNav Investors, as applicable. If withdrawn, a demand for an Underwritten Shelf Takedown
shall constitute a demand for an Underwritten Shelf Takedown for purposes of Section 2.1.3, unless the Demanding Holders reimburse
the Company for all Registration Expenses with respect to such Underwritten Shelf Takedown. Following the receipt of any Withdrawal Notice,
the Company shall promptly forward such Withdrawal Notice to any other Holders that had elected to participate in such Shelf Takedown.

 

2.2 Piggyback
Registration.

 

2.2.1 Piggyback
Rights. Subject to Section 2.4.3, if the Company or any Holder proposes to conduct a registered offering of, or if the
Company proposes to file a Registration Statement under the Securities Act with respect to the Registration of, equity securities, or
securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own account or for the
account of stockholders of the Company (or by the Company and by the stockholders of the Company including, without limitation, an Underwritten
Shelf Takedown pursuant to Section 2.1.3 hereof), other than a Registration Statement (or any registered offering with respect
thereto) (i) filed in connection with any employee stock option or other benefit plan, (ii) pursuant to a Registration Statement on Form
S-4 (or similar form that relates to a transaction subject to Rule 145 under the Securities Act or any successor rule thereto), (iii)
for an offering of debt that is convertible into equity securities of the Company or (iv) for a dividend reinvestment plan, then the Company
shall give written notice of such proposed offering to all of the Holders of Registrable Securities and the FF Beneficial Investor as
soon as practicable but not less than ten (10) days before the anticipated filing date of such Registration Statement or, in the case
of an Underwritten Offering pursuant to a Shelf Registration, the applicable “red herring” prospectus or prospectus supplement
used for marketing such offering, which notice shall (A) describe the amount and type of securities to be included in such offering, the
intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, in such offering, and (B)
offer to all of the Holders of Registrable Securities the opportunity to include in such registered offering such number of Registrable
Securities as such Holders may request in writing within five (5) days after receipt of such written notice (such registered offering,
a “Piggyback Registration”). Subject to Section 2.2.2, the Company shall, in good faith, cause such
Registrable Securities to be included in such Piggyback Registration and, if applicable, shall use its commercially reasonable efforts
to cause the managing Underwriter or Underwriters of such Piggyback Registration to permit the Registrable Securities requested by the
Holders pursuant to this Section 2.2.1 to be included therein on the same terms and conditions as any similar securities of
the Company included in such registered offering and to permit the sale or other disposition of such Registrable Securities in accordance
with the intended method(s) of distribution thereof. The inclusion of any Holder’s Registrable Securities in a Piggyback Registration
shall be subject to such Holder agreement to enter into an underwriting agreement in customary form with the Underwriter(s) selected for
such Underwritten Offering. Notwithstanding anything to the contrary in the foregoing, neither the FF Investor nor the FF Beneficial Investor
shall be required to execute any agreement, instrument or other document pursuant to this Section 2.2 unless such agreement, instrument
or other document contains a limitation of liability provision in the form of Section 6.10.

 

    7

    

    

 

2.2.2 Reduction
of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Offering that is to be a Piggyback Registration,
in good faith, advises the Company and the Holders of Registrable Securities (and the FF Beneficial Investor) participating in the Piggyback
Registration that the dollar amount or number of shares of Common Stock or other equity securities that the Company desires to sell, taken
together with (i) the shares of Common Stock or other equity securities, if any, as to which Registration or a registered offering has
been demanded pursuant to separate written contractual arrangements with persons or entities other than the Holders of Registrable Securities
hereunder, (ii) the Registrable Securities as to which registration has been requested pursuant to Section 2.2 hereof, and
(iii) the shares of Common Stock or other equity securities, if any, as to which Registration or a registered offering has been requested
pursuant to separate written contractual piggy-back registration rights of other stockholders of the Company, exceeds the Maximum Number
of Securities, then:

 

(a) If
the Registration or registered offering is undertaken for the Company’s account, the Company shall include in any such Registration
or registered offering: (A) first, the shares of Common Stock or other equity securities that the Company desires to sell, which can be
sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been
reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities
pursuant to Section 2.2.1, pro rata, based on the respective number of Registrable Securities that each Holder has requested
be included in such Underwritten Offering and the aggregate number of Registrable Securities that the Holders have requested to be included
in such Underwritten Offering, which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the extent that
the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the shares of Common Stock or other equity
securities, if any, as to which Registration or a registered offering has been requested pursuant to written contractual piggy-back registration
rights of other stockholders of the Company, which can be sold without exceeding the Maximum Number of Securities;

 

(b) If
the Registration or registered offering is pursuant to a request by persons or entities other than the Holders of Registrable Securities,
then the Company shall include in any such Registration or registered offering (A) first, the shares of Common Stock or other equity securities,
if any, of such requesting persons or entities, other than the Holders of Registrable Securities, which can be sold without exceeding
the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing
clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to Section 2.2.1,
pro rata, based on the respective number of Registrable Securities that each Holder has requested be included in such Underwritten Offering
and the aggregate number of Registrable Securities that the Holders have requested to be included in such Underwritten Offering, which
can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not
been reached under the foregoing clauses (A) and (B), the shares of Common Stock or other equity securities that the Company desires to
sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities
has not been reached under the foregoing clauses (A), (B) and (C), the shares of Common Stock or other equity securities for the account
of other persons or entities that the Company is obligated to register pursuant to separate written contractual arrangements with such
persons or entities, which can be sold without exceeding the Maximum Number of Securities; and

 

(c) If
the Registration or registered offering is pursuant to a request by Holder(s) of Registrable Securities pursuant to Section 2.1
hereof, then the Company shall include in any such Registration or registered offering securities pursuant to Section 2.1.5.

 

2.2.3 Piggyback
Registration Withdrawal. Any Holder of Registrable Securities (other than a Demanding Holder, whose right to withdrawal from an Underwritten
Shelf Takedown, and related obligations, shall be governed by Section 2.1.5) shall have the right to withdraw from a Piggyback
Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of
his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed
with the Commission with respect to such Piggyback Registration or, in the case of a Piggyback Registration pursuant to a Shelf Registration,
the filing of the applicable “red herring” prospectus or prospectus supplement with respect to such Piggyback Registration
used for marketing such transaction. The Company (whether on its own good faith determination or as the result of a request for withdrawal
by persons pursuant to separate written contractual obligations) may withdraw a Registration Statement filed with the Commission in connection
with a Piggyback Registration (which, in no circumstance, shall include the Shelf Registration) at any time prior to the effectiveness
of such Registration Statement. Notwithstanding anything to the contrary in this Agreement (other than Section 2.1.5), the
Company shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal
under this Section 2.2.3.

 

    8

    

    

 

2.2.4 Unlimited
Piggyback Registration Rights. For purposes of clarity, subject to Section 2.1.5, any Piggyback Registration effected
pursuant to Section 2.2 hereof shall not be counted as a demand for an Underwritten Shelf Takedown under Section 2.1.4
hereof.

 

2.3 Market
Stand-off. In connection with any Underwritten Offering of equity securities of the Company (other than a Block Trade), each Holder
of Registrable Securities agrees that it shall not Transfer any shares of Common Stock or other equity securities of the Company (other
than those included in such offering pursuant to this Agreement), without the prior written consent of the Company, during the sixty (60)-day
period (or such shorter time agreed to by the managing Underwriter(s)) beginning on the date of pricing of such offering, except in the
event the Underwriters managing the offering otherwise agree by written consent. Each Holder of Registrable Securities agrees to execute
a customary lock-up agreement in favor of the Underwriters to such effect (in each case on substantially the same terms and conditions
as all such Holders). For the sake of clarity, no Holder shall be obligated under the provisions of this Section 2.3 to the extent
such Holder no longer owns Registrable Securities.

 

2.4 Block
Trades.

 

2.4.1 Notwithstanding
the foregoing, at any time and from time to time when an effective Shelf Registration is on file with the Commission, if a Demanding Holder
wishes to engage in an underwritten registered offering not involving a “roadshow,” an offer commonly known as a “block
trade” (a “Block Trade”), with a total offering price reasonably expected to exceed, in the aggregate,
either (x) $50 million or (y) all remaining Registrable Securities held by the Demanding Holder, then notwithstanding the time periods
provided for in Section 2.1.3, such Demanding Holder only need to notify the Company of the Block Trade at least five (5)
business days prior to the day such offering is to commence and the Company shall as expeditiously as possible use its commercially reasonable
efforts to facilitate such Block Trade; provided that the Demanding Holders representing a majority of the Registrable Securities
wishing to engage in the Block Trade shall use commercially reasonable efforts to work with the Company and any Underwriters prior to
making such request in order to facilitate preparation of the registration statement, prospectus and other offering documentation related
to the Block Trade.

 

2.4.2 Prior
to the filing of the applicable “red herring” prospectus or prospectus supplement used in connection with a Block Trade, a
majority-in-interest of the Demanding Holders initiating such Block Trade shall have the right to submit a Withdrawal Notice to the Company
and the Underwriter or Underwriters (if any) of their intention to withdraw from such Block Trade. Notwithstanding anything to the contrary
in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a block trade prior to its
withdrawal under this Section 2.4.2.

 

2.4.3 Notwithstanding
anything to the contrary in this Agreement, Section 2.2 hereof shall not apply to a Block Trade initiated by a Demanding Holder
pursuant to this Agreement.

 

2.4.4 The
Demanding Holder in a Block Trade shall have the right to select the Underwriters for such Block Trade (which shall consist of one or
more reputable nationally recognized investment banks).

Agreement, which shall be of no further force or effect.

of distribution thereof, and pursuant thereto the Company shall, as expeditiously as possible:

 

3.1.1 prepare
and file with the Commission as soon as practicable a Registration Statement with respect to such Registrable Securities and use its commercially
reasonable efforts to cause such Registration Statement to become effective and remain effective until all Registrable Securities covered
by such Registration Statement have been sold;

 

3.1.2 prepare
and file with the Commission such amendments and post-effective amendments to the Registration Statement, and such supplements to the
Prospectus, as may be requested by any Holder or any Underwriter of Registrable Securities or as may be required by the rules, regulations
or instructions applicable to the registration form used by the Company or by the Securities Act or rules and regulations thereunder to
keep the Registration Statement effective until all Registrable Securities covered by such Registration Statement are sold in accordance
with the intended plan of distribution set forth in such Registration Statement or supplement to the Prospectus;

 

3.1.3 prior
to filing a Registration Statement or Prospectus, or any amendment or supplement thereto, furnish without charge to the Underwriters,
if any, and each Holder of Registrable Securities included in such Registration, the FF Beneficial Investor (provided that the FF Investor
remains a Holder holding such Registrable Securities) and each such Holder’s legal counsel, copies of such Registration Statement
as proposed to be filed, each amendment and supplement to such Registration Statement (in each case including all exhibits thereto and
documents incorporated by reference therein), the Prospectus included in such Registration Statement (including each preliminary Prospectus),
and such other documents as the Underwriters and each Holder of Registrable Securities included in such Registration or the FF Beneficial
Investor or the legal counsel for any such Holders may request in order to facilitate the disposition of the Registrable Securities owned
by such Holders;

 

3.1.4 prior
to any public offering of Registrable Securities, use its commercially reasonable efforts to (i) register or qualify the Registrable Securities
covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United States
as any Holder of Registrable Securities included in such Registration Statement (in light of their intended plan of distribution) may
request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered
with or approved by such other governmental authorities as may be necessary by virtue of the business and operations of the Company and
do any and all other acts and things that may be necessary or advisable to enable the Holders of Registrable Securities included in such
Registration Statement to consummate the disposition of such Registrable Securities in such jurisdictions; provided, however,
that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required
to qualify or take any action to which it would be subject to general service of process or taxation in any such jurisdiction where it
is not then otherwise so subject;

 

3.1.5 cause
all such Registrable Securities to be listed on each securities exchange or automated quotation system on which similar securities issued
by the Company are then listed;

 

3.1.6 provide
a transfer agent or warrant agent, as applicable, and registrar for all such Registrable Securities no later than the effective date of
such Registration Statement;

 

3.1.7 advise
each seller of such Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any
stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or threatening of any proceeding
for such purpose and promptly use its commercially reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal
if such stop order should be issued;

 

    10

    

    

 

3.1.8 at
least five (5) days prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such Registration
Statement or Prospectus or any document that is to be incorporated by reference into such Registration Statement or Prospectus, furnish
a copy thereof to each seller of such Registrable Securities and its counsel, including, without limitation, providing copies promptly
upon receipt of any comment letters received with respect to any such Registration Statement or Prospectus;

 

3.1.9 notify
the Holders and the FF Beneficial Investor at any time when a Prospectus relating to such Registration Statement is required to be delivered
under the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement, as
then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in Section 3.4 hereof;

 

3.1.10 permit
a representative of the Holders and the FF Beneficial Investor, the Underwriters, if any, and any attorney or accountant retained by such
Holders, the FF Beneficial Investor or Underwriter to participate, at each such person’s own expense, in the preparation of the
Registration Statement, and cause the Company’s officers, directors and employees to supply all information reasonably requested
by any such representative, Underwriter, attorney or accountant in connection with the Registration; provided, however,
that such representatives or Underwriters agree to confidentiality arrangements reasonably satisfactory to the Company, prior to the release
or disclosure of any such information;

 

3.1.11 obtain
a “cold comfort” letter from the Company’s independent registered public accountants in the event of an Underwritten
Registration which the participating Holders and the FF Beneficial Investor may rely on, in customary form and covering such matters of
the type customarily covered by “cold comfort” letters as the managing Underwriter may reasonably request, and reasonably
satisfactory to a majority-in-interest of the participating Holders;

 

3.1.12 on
the date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, dated such date, of counsel
representing the Company for the purposes of such Registration, addressed to the Holders and the FF Beneficial Investor, the placement
agent or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of
which such opinion is being given as the Holders, the FF Beneficial Investor, placement agent, sales agent, or Underwriter may reasonably
request and as are customarily included in such opinions and negative assurance letters, and reasonably satisfactory to a majority in
interest of the participating Holders;

 

3.1.13 in
the event of any Underwritten Offering, enter into and perform its obligations under an underwriting agreement, in usual and customary
form, with the managing Underwriter of such offering;

 

3.1.14 make
available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12)
months beginning with the first day of the Company’s first full calendar quarter after the effective date of the Registration Statement
which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule promulgated
thereafter by the Commission);

 

3.1.15 with
respect to an Underwritten Offering pursuant to Section 2.1.4, use its commercially reasonable efforts to make available senior
executives of the Company to participate in customary “road show” presentations that may be reasonably requested by the Underwriter
in such Underwritten Offering; and

 

3.1.16 otherwise,
in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Holders or the FF Beneficial
Investor, in connection with such Registration.

 

Notwithstanding the foregoing, the Company shall
not be required to provide any documents or information to an Underwriter if such Underwriter has not then been named with respect to
the applicable Underwritten Offering.

 

3.2 Registration
Expenses. The Registration Expenses of all Registrations shall be borne by the Company. It is acknowledged by the Holders that the
Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ commissions
and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition of “Registration Expenses,”
all reasonable fees and expenses of any legal counsel representing the Holders.

 

    11

    

    

 

3.3 Requirements
for Participation in Underwritten Offerings. Notwithstanding anything in this Agreement to the contrary, if any Holder does not provide
the Company with its requested Holder Information, the Company may exclude such Holder’s Registrable Securities from the applicable
Registration Statement or Prospectus if the Company determines, based on the advice of counsel, that such information is necessary to
effect the registration and such Holder continues thereafter to withhold such information. No person may participate in any Underwritten
Offering for equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless such person (i) agrees
to sell such person’s securities on the basis provided in any underwriting arrangements approved by the Company and (ii) completes
and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting agreements and other customary
documents as may be reasonably required under the terms of such underwriting arrangements. The exclusion of a Holder’s Registrable
Securities as a result of this Section 3.3 shall not affect the registration of the other Registrable Securities to be included
in such Registration.

 

3.4 Suspension
of Sales; Adverse Disclosure.

 

3.4.1 Upon
receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Holders shall
forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended Prospectus correcting
the Misstatement (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable
after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be resumed.

 

3.4.2 Subject
to Section 3.4.4, if the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration
at any time would (a) require the Company to make an Adverse Disclosure, (b) require the inclusion in such Registration Statement of financial
statements that are unavailable to the Company for reasons beyond the Company’s control, or (c) in the good faith judgment of the
majority of the Board, be detrimental to the Company and the majority of the Board concludes as a result that it is advisable to defer
such filing, initial effectiveness or continued use at such time, the Company may, upon giving prompt written notice of such action to
the Holders and the FF Beneficial Investor, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement
for the shortest period of time determined in good faith by the Company to be necessary for such purpose. In the event the Company exercises
its rights under this Section 3.4.2, the Holders agree to suspend, immediately upon their receipt of the notice referred to above,
their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities.

 

3.4.3 Subject
to Section 3.4.4, (a) during the period starting with the date sixty (60) days prior to the Company’s good faith estimate
of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company-initiated
Registration and provided that the Company continues to actively employ, in good faith, all commercially reasonable efforts to maintain
the effectiveness of the applicable Registration Statement, or (b) if, pursuant to Section 2.1.4, Holders (or the FF Beneficial
Investor) have requested an Underwritten Shelf Takedown and the Company and Holders are unable to obtain the commitment of underwriters
to firmly underwrite such offering, the Company may, upon giving prompt written notice of such action to the Holders (or the FF Beneficial
Investor, if applicable), delay any other registered offering pursuant to Sections 2.1.4 or 2.4.

 

3.4.4 The
right to delay or suspend any filing, initial effectiveness or continued use of a Registration Statement pursuant to Section 3.4.2
or a registered offering pursuant to Section 3.4.3 shall be exercised by the Company, in the aggregate, not more than three (3)
times in any twelve-month period, and any such delay or suspension shall last for no more than sixty (60) days.

 

3.4.5 The
Company shall as promptly as commercially practicable notify the Holders and the FF Beneficial Investor of the expiration of any period
during which it exercised its rights under this Section 3.4.

 

3.5 Reporting
Obligations. As long as any Holder shall own Registrable Securities (or in the case of the FF Investor, as long as it is the holder
of Registrable Securities), the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to file
timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company
after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders
and the FF Beneficial Investor with true and complete copies of all such filings. The Company further covenants that it shall take such
further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell shares
of the Common Stock held by such Holder without registration under the Securities Act within the limitation of the exemptions provided
by Rule 144 (or any successor rule promulgated thereafter by the Commission), including providing any legal opinions. Upon the request
of any Holder, the Company shall deliver to such Holder (and to the FF Beneficial Investor in the case that the FF Investor has made such
request) a written certification of a duly authorized officer as to whether it has complied with such requirements.

ARTICLE IV

INDEMNIFICATION AND CONTRIBUTION

 

4.1 Indemnification.

 

4.1.1 The
Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities (which for the purposes of this Section
4.1 shall include the FF Beneficial Investor for so long as the FF Investor is a holder of Registrable Securities), its officers,
members, managers, and directors (if applicable) and each person who controls such Holder (within the meaning of the Securities Act) against
all losses, claims, damages, liabilities and expenses (including attorneys’ fees) resulting from any untrue or alleged untrue statement
of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement
thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein
not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder
expressly for use therein. The Company shall indemnify the Underwriters, their officers and directors and each person who controls such
Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to the indemnification
of the Holder.

 

4.1.2 In
connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to
the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration
Statement or Prospectus (the “Holder Information”) and, to the
extent permitted by law, shall indemnify the Company, its directors and officers and agents and each person who controls the Company (within
the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including without limitation reasonable
attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary
Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information
or affidavit so furnished in writing by such Holder expressly for use therein; provided, however, that the obligation
to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder
of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable
Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers,
directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in
the foregoing with respect to indemnification of the Company.

 

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

 

    13

    

    

 

4.1.4 The
indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on
behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the transfer
of securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions
as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s
indemnification is unavailable for any reason.

 

4.1.5 If
the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient
to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the
indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party
as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault
of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the
indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including
any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates
to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s
relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however,
that the liability of any Holder under this Section 4.1.5 shall be limited to the amount of the net proceeds received
by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other
liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 4.1.1, 4.1.2 and 4.1.3 above,
any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The
parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.1.5 were
determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred
to in this Section 4.1.5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution pursuant to this Section 4.1.5 from any person who was not
guilty of such fraudulent misrepresentation.

 

    14

    

    

 

ARTICLE V

LOCK-UP

 

5.1 Lock-up.
Subject to Section 5.2, each Holder agrees that, until the end of the Applicable Lock-Up Period (as defined below), it, he
or she shall not Transfer (i) any Transaction Shares, (ii) Private Placement Warrants, or Warrant Shares. The “Applicable
Lock-Up Period” shall mean:

 

(a) With
respect to the Transaction Shares held by any of the Initial Investors, one year after the Closing Date; provided, however,
that such Applicable Lock-Up Period shall terminate earlier if, for at least 20 trading days within any 30-trading day period commencing
at least 150 days after the Closing Date, the last sale price of the Common Stock equals or exceeds $12.00 per share (as adjusted for
stock splits, stock dividends, reorganizations, recapitalizations and the like);

 

(b) With
respect to the Transaction Shares held by any of the NextNav Investors, 180 days after the Closing Date; provided, however,
that such Applicable Lock-Up Period shall terminate earlier with respect to 50% of the Transactions Shares held by each of the NextNav
Investors if, for at least 20 trading days within any 30-trading day period commencing at least 60 days after the Closing Date, the last
sale price of the Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations
and the like); and

 

(c) With
respect to the Private Placement Warrants and Warrant Shares, 30 days after the Closing Date.

 

5.2 Permitted
Transfers. Notwithstanding the provisions set forth in Section 5.1, any Holder or its Permitted Transferees may Transfer
the Transaction Shares, Private Placement Warrants or Warrant Shares during the Applicable Lock-Up Period: (a) to (i) the Company’s
officers or directors, (ii) any affiliates or family members of the Company’s officers or directors, (iii) any direct or indirect
partners, members or equity holders of the Sponsor or any related investment funds or vehicles controlled or managed by such persons or
their respective affiliates, or (iv) any direct or indirect partners, members or equity holders of any NextNav Investor, any affiliates
of any NextNav Investor or any related investment funds or vehicles controlled or managed by such persons or their respective affiliates;
(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 virtue of the laws of the State of Delaware or the Sponsor’s limited liability company
agreement upon dissolution of the Sponsor; (f) in connection with any bona fide mortgage, encumbrance or pledge to a financial institution
in connection with any bona fide loan or debt transaction or enforcement thereunder; (g) to the Company; (h) in connection with a liquidation,
merger, stock exchange, reorganization, tender offer approved by the Board or a duly authorized committee thereof or other similar transaction
which results in all of the Company’s stockholders having the right to exchange their shares Common Stock for cash, securities or
other property subsequent to the Closing Date; or (i) in the case of the FF Investor and the FF Beneficial Investor, to any FF Permitted
Transferee; provided, however, that in the case of clauses (a) through (e) these permitted transferees must enter into a
written agreement with the Company agreeing to be bound by the transfer restrictions in this ARTICLE V.

 

5.3 Non-Transaction
Shares. For the avoidance of doubt, with respect to the Sponsor, only Common Stock issued in exchange for the Founder Shares shall
be considered Transaction Shares, and any other Common Stock held by the Sponsor or any of its affiliates shall not be considered Transaction
Shares or be subject to this ARTICLE V (other than the Warrant Shares).

 

    15

    

    

 

ARTICLE VI

thirty (30) days after delivery of such notice as provided in this Section 6.1.

 

6.2 Assignment;
No Third Party Beneficiaries.

 

6.2.1 This
Agreement and the rights, duties and obligations of the Company hereunder may not be assigned or delegated by the Company in whole or
in part.

 

6.2.2 Prior
to the expiration of the Applicable Lock-Up Period, as the case may be, no Holder may assign or delegate such Holder’s rights, duties
or obligations under this Agreement, in whole or in part, except in connection with a transfer of Registrable Securities by such Holder
to a Permitted Transferee but only if such Permitted Transferee agrees to become bound by the transfer restrictions set forth in this
Agreement.

 

6.2.3 This
Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the parties and its successors and
the permitted assigns of the Holders, which shall include Permitted Transferees. (and in the case of the FF Investor and the FF Beneficial
Investor, shall also include any FF Permitted Transferee).

 

6.2.4 This
Agreement shall not confer any rights or benefits on any persons that are not parties hereto, other than as expressly set forth in this
Agreement and Section 6.2 hereof.

 

6.2.5 No
assignment by any party hereto of such party’s rights, duties and obligations hereunder shall be binding upon or obligate the Company
unless and until the Company shall have received (i) written notice of such assignment as provided in Section 6.1 hereof
and (ii) the written agreement of the assignee, in a form attached hereto as Exhibit A, to be bound by the terms and provisions
of this Agreement. Any transfer or assignment made
other than as provided in this Section 6.2 shall be null and void. Notwithstanding the foregoing, the FF Investor
and the FF Beneficial Investor may transfer or assign any of their respective rights or obligations under this Agreement, without prior
written consent, to any FF Permitted Transferee, or otherwise with the consent of the Company. Following such transfer or assignment to
a FF Permitted Transferee, the FF Permitted Transferee shall be entitled to receive the benefit of the terms of this Agreement, as if
such FF Permitted Transferee had executed this Agreement.

 

6.3 Counterparts.

YORK RESIDENTS ENTERED INTO AND TO BE PERFORMED ENTIRELY WITHIN NEW YORK, WITHOUT REGARD TO THE CONFLICT OF LAW PROVISIONS OF SUCH JURISDICTION

OF NEW YORK.

 

    16

    

    

 

6.5 Trial
By Jury. EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE
COMPLICATED AND DIFFICULT ISSUES, AND, THEREFORE, EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT TO ANY ACTION DIRECTLY OR INDIRECTLY ARISING
OUT OF, UNDER OR IN CONNECTION WITH OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

 

6.6 Amendments
and Modifications. Upon the written consent of the Company and the Holders of at least a majority in interest of the Registrable Securities
at the time in question, compliance with any of the provisions, covenants and conditions set forth in this Agreement may be waived, or
any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding
the foregoing, any amendment hereto or waiver hereof that adversely affects one Holder, solely in its capacity as a holder of the shares
of capital stock of the Company, in a manner that is materially different from the other Holders (in such capacity) shall require the
consent of the Holder so affected. No course of dealing between any Holder or the Company and any other party hereto or any failure or
delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement shall operate as a waiver of any
rights or remedies of any Holder or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party
shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party.

 

6.7 Other

Subscription Agreements and (ii) as provided in the Warrant Agreement, dated as of October 15, 2020, between the SPAC and Continental
Stock Transfer & Trust Company, the Company represents and warrants that no person, other than a Holder of Registrable Securities
or the FF Beneficial Investor (for so long as the FF Investor is a Holder of Registrable Securities), has any right to require the Company
to register any securities of the Company for sale or to include such securities of the Company in any Registration filed by the Company
for the sale of securities for its own account or for the account of any other person.

 

6.8 Term.
This Agreement shall terminate with respect to any Holder on the date that such Holder no longer holds any Registrable Securities. The
provisions of Section 3.5 and ARTICLE IV shall survive any termination.

 

6.9 Holder
Information. Each Holder agrees, if requested in writing, to represent to the Company the total number of Registrable Securities held
by such Holder in order for the Company to make determinations hereunder.

 

6.10 The Northern Trust Company Limitation
of Liability. The FF Investor enters into and is liable under (a) this Agreement, (b) any other document or agreement which the FF
Investor may be required to provide under this Agreement and (c) any document or agreement executed by the Company or any other person
as agent or attorney of the FF Investor under this Agreement, only in its capacity as custodian for the FF Beneficial Investor, and to
the extent that it is actually indemnified by the FF Beneficial Investor.  To the extent that this Section 6.10 operates
to reduce the amounts for which the FF Investor would otherwise be liable to any person, the FF Beneficial Investor will pay or procure
the payment of such shortfall to such person.
