WARRANT AGREEMENT

 

Dated as of August 18,
2016

 

THIS
WARRANT AGREEMENT (this “Agreement”), dated as of August 18, 2016, is by and between Stellar Acquisition
III Inc., a Marshall Islands corporation (the “Company”), and Continental Stock Transfer & Trust
Company, a New York corporation, as warrant agent (the “Warrant Agent”, also referred to herein as the
“Transfer Agent”).

 

WHEREAS,
the Company has entered into that certain Second Amended and Restated Sponsors Warrants Purchase Agreement dated as of August 12,
2016 (the “Private Placement Warrants Purchase Agreement”), with Astra Maritime Corp., Dominium Investments
Inc., Magellan Investments Corp. and Firmus Investments Inc. (the “Sponsors”), pursuant to which the
Sponsors will purchase an aggregate of 7,650,000 warrants (or up to 8,430,000 warrants if the underwriters’ over-allotment
option is exercised in full) simultaneously with the closing of the Offering (as defined below) bearing the legend set forth in Exhibit
B hereto (the “Private Placement Warrants”) at a purchase price of $0.50 per Private Placement
Warrant; and

 

WHEREAS,
the Company is engaged in an initial public offering (the “Offering”) of units of the Company’s
equity securities, each such unit comprised of one share of Common Stock (as defined below) and one Public Warrant (as defined
below) (the “Units”) and, in connection therewith, has determined to issue and deliver (i) up to 7,475,000
warrants (including up to 975,000 warrants subject to the Over-allotment Option) to public investors in the Offering (the “Public
Warrants”) and (ii) 130,000 warrants (underlying a unit purchase option) to the underwriters of the Offering (the
“Underwriters’ Warrants” and, together with the Private Placement Warrants and Public Warrants,
the “Warrants”). Each Warrant entitles the holder thereof to purchase one share of common stock of the
Company, par value $0.0001 per share (“Common Stock”), for $11.50 per share, subject to adjustment as
described herein; and

 

WHEREAS,
the Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement
on Form S-1, No. 333—212377 (the “Registration Statement”) and prospectus (the “Prospectus”),
for the registration, under the Securities Act of 1933, as amended (the “Securities Act”), of the Units,
the Public Warrants and the Common Stock included in the Units; and

 

WHEREAS,
the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection
with the issuance, registration, transfer, exchange, redemption and exercise of the Warrants; and

 

WHEREAS,
the Company desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised,
and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent, and the holders of the Warrants;
and

 

WHEREAS,
all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company
and countersigned by or on behalf of the Warrant Agent, as provided herein, the valid, binding and legal obligations of the Company,
and to authorize the execution and delivery of this Agreement.

 

    

     

    

 

NOW, THEREFORE, in
consideration of the mutual agreements herein contained, the parties hereto agree as follows:

 

1. Appointment
of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants, and the Warrant
Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this
Agreement.

 

2. Warrants.

 

2.1 [Reserved].

 

2.2 Effect
of Countersignature. If a physical certificate is issued, unless and until countersigned by the Warrant Agent pursuant to this
Agreement, a Warrant shall be invalid and of no effect and may not be exercised by the holder thereof.

 

2.3 Registration.

 

2.3.1 Warrant Register.
The Warrant Agent shall maintain books (the “Warrant Register”), for the registration of original issuance
and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants in book-entry form, the Warrant Agent
shall issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance
with instructions delivered to the Warrant Agent by the Company. Ownership of beneficial interests in the Public Warrants shall
be shown on, and the transfer of such ownership shall be effected through, records maintained by institutions that have accounts
with the Depository Trust Company (the “Depository”) (such institution, with respect to a Warrant in
its account, a “Participant”).

 

If the Depository subsequently
ceases to make its book-entry settlement system available for the Public Warrants, the Company may instruct the Warrant Agent regarding
making other arrangements for book-entry settlement. In the event that the Public Warrants are not eligible for, or it is no longer
necessary to have the Public Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the
Depository to deliver to the Warrant Agent for cancellation each book-entry Public Warrant, and the Company shall instruct the
Warrant Agent to deliver to the Depository definitive certificates in physical form evidencing such Warrants which shall be in
the form annexed hereto as Exhibit A.

 

The certificates, if issued,
shall be signed by, or bear the facsimile signature of, the Chairman of the Board, President, Chief Executive Officer, Chief Financial
Officer, Secretary or other principal officer of the Company. In the event the person whose facsimile signature has been placed
upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued,
it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance.

 

2.3.2 Registered Holder.
Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and treat the
person in whose name such Warrant is registered in the Warrant Register (the “Registered Holder”) as
the absolute owner of such Warrant and of each Warrant represented thereby, for the purpose of any exercise thereof, and for all
other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

 

2.4 Detachability
of Warrants. The Common Stock and Public Warrants comprising the Units shall begin separate trading on the 52nd day following
the date of the Prospectus or, if such 52nd day is not on a day, other than a Saturday, Sunday or federal holiday, on which banks
in New York City are generally open for normal business (a “Business Day”), then on the immediately succeeding
Business Day following such date, or earlier (the “Detachment Date”) with the consent of Maxim Group
LLC, as representative of the several underwriters, but in no event shall the Common Stock and the Public Warrants comprising the
Units be separately traded until (A) the Company has filed a current report on Form 8-K with the Commission containing an audited
balance sheet reflecting the receipt by the Company of the gross proceeds of the Offering, including the proceeds received by the
Company from the exercise by the underwriters of their right to purchase additional shares of Common Stock in the Offering (the
“Over-allotment Option”), if the Over-allotment Option is exercised prior to the filing of the Form 8-K,
and (B) the Company issues a press release and files with the Commission a current report on Form 8-K announcing when such separate
trading shall begin.

2.5 Warrant
Attributes.

 

2.5.1
Private Placement Warrants. The Private Placement Warrants shall be identical to the Public Warrants, except that so long
as they are held by the Sponsors or any of their Permitted Transferees (as defined below) the Private Placement Warrants: (i) may
be exercised for cash or on a cashless basis, pursuant to subsection 3.3.1(c) hereof, (ii) may not be transferred,
assigned or sold until thirty (30) days after the completion by the Company of an initial Business Combination (as defined below),
and (iii) shall not be redeemable by the Company; provided, however, that in the case of (ii), the Private
Placement Warrants and any shares of Common Stock held by the members of any Sponsor and issued upon exercise of the Private Placement
Warrants may be transferred by the holders thereof:

 

(a) in the case of an individual,
by gift to such person’s immediate family or to a trust, the beneficiary of which is a member of such person’s immediate
family, an affiliate of such person or to a charitable organization,

 

(b)
to the Company’s officers or directors, any affiliate or family member of any of the Company’s officers or directors
or any member of any Sponsor, or any affiliate of any Sponsor or its members,

 

(c)
in the case of an individual, by virtue of the laws of descent and distribution upon death of such person,

 

(d)
in the case of an individual, pursuant to a qualified domestic relations order,

 

(e)
through private sales or transfers made in connection with the consummation of the Company’s initial Business Combination
at prices no greater than the price at which the Warrants were originally purchased, or

 

(f)
in the event of the Company’s liquidation prior to the completion of the initial Business Combination,

 

(g)
in the event that, subsequent to the consummation of the Company’s initial Business Combination, the Company consummates
a merger, stock exchange or other similar transaction that results in all of the holders of the Company’s equity securities
issued in the Offering having the right to exchange their shares of Common Stock for cash, securities or other property; provided, however,
that, in the case of clauses (a) through (e), these transferees (the “Permitted Transferees”) enter into
a written agreement with the Company agreeing to be bound by the transfer restrictions in this Agreement.

 

2.5.2
Underwriters’ Warrants. The Underwriters’ Warrants, when issued, shall have the same terms and be in the same
form as the Public Warrants.

 

3. Terms
and Exercise of Warrants.

 

3.1 Warrant
Price. Each Warrant shall, when countersigned by the Warrant Agent, entitle the Registered Holder thereof, subject to the provisions
of such Warrant and of this Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the
price of $11.50 per share, subject to the adjustments provided in Section 4 hereof and in the last sentence of
this Section 3.1. The term “Warrant Price” as used in this Agreement shall mean the price per share at
which shares of Common Stock may be purchased at the time a Warrant is exercised. The Company in its sole discretion may lower
the Warrant Price at any time prior to the Expiration Date (as defined below) for a period of not less than twenty (20) Business
Days, provided, that the Company shall provide at least twenty (20) days prior written notice of such reduction to Registered Holders
of the Warrants and, provided further that any such reduction shall be identical among all of the Warrants.

 

    3

     

    

 

3.2 Duration
of Warrants. A Warrant may be exercised only during the period (the “Exercise Period”) commencing
on the later of: (i) the date that is thirty (30) days after the first date on which the Company completes a merger, capital stock
exchange, asset acquisition, stock purchase, reorganization or similar business combination, involving the Company and one or more
businesses (a “Business Combination”), or (ii) the date that is twelve (12) months from the date of the
closing of the Offering, and terminating at 5:00 p.m., New York City time on the earlier to occur of: (x) the date that is five
(5) years after the date on which the Company completes its initial Business Combination, (y) the liquidation of the Company’s
trust account in accordance with the Company’s amended and restated certificate of incorporation, as amended from time to
time, if the Company fails to consummate a Business Combination, or (z) other than with respect to the Private Placement Warrants,
the Redemption Date (as defined below) as provided in Section 6.2 hereof (the “Expiration Date”); provided, however,
that the exercise of any Warrant shall be subject to the satisfaction of any applicable conditions, as set forth in subsection
3.3.2 below, with respect to an effective registration statement. Except with respect to the right to receive the Redemption
Price (as defined below) (other than with respect to a Private Placement Warrant) in the event of a redemption (as set forth in Section
6 hereof), each Warrant (other than a Private Placement Warrant in the event of a redemption) not exercised on or before
the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease
at 5:00 p.m. New York City time on the Expiration Date. The Company in its sole discretion may extend the duration of the Warrants
by delaying the Expiration Date; provided, that the Company shall provide at least twenty (20) days prior written notice
of any such extension to Registered Holders of the Warrants and, provided further that any such extension shall be identical in
duration among all the Warrants.

 

3.3 Exercise
of Warrants.

 

3.3.1 Payment.
Subject to the provisions of the Warrant and this Agreement, a Warrant, when countersigned by the Warrant Agent, may be exercised
by the Registered Holder thereof by surrendering it, at the office of the Warrant Agent, or at the office of its successor as Warrant
Agent, in the Borough of Manhattan, City and State of New York, with the subscription form, as set forth in the Warrant, duly executed,
and by paying in full the Warrant Price for each full share of Common Stock as to which the Warrant is exercised and any and all
applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the shares of Common Stock
and the issuance of such Common Stock, as follows:

 

(a)
in lawful money of the United States, in good certified check or good bank draft payable to the order of the Warrant Agent;

 

(b)
in the event of a redemption pursuant to Section 6 hereof in which the Company’s board of directors (the
“Board”) has elected to require all holders of the Warrants to exercise such Warrants on a “cashless
basis,” by surrendering the Warrants for that number of shares of Common Stock equal to the quotient obtained by dividing
(x) the product of the number of shares of Common Stock underlying the Warrants, multiplied by the difference between the Warrant
Price and the “Fair Market Value”, as defined in this subsection 3.3.1(b) by (y) the Fair Market Value.
Solely for purposes of this subsection 3.3.1(b) and Section 6.3, the “Fair Market Value”
shall mean the average last sale price of the Common Stock for the ten (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 the Warrants, pursuant to Section 6hereof;

 

(c)
with respect to any Private Placement Warrant, so long as such Private Placement Warrant is held by any Sponsor or a Permitted
Transferee, by surrendering the Warrants for that number of shares of Common Stock equal to the quotient obtained by dividing (x)
the product of the number of shares of Common Stock underlying the Warrants, multiplied by the difference between the Warrant Price
and the “Fair Market Value”, as defined in this subsection 3.3.1(c), by (y) the Fair Market Value. Solely
for purposes of this subsection 3.3.1(c), the “Fair Market Value” shall mean the average last sale price
of the Common Stock for the ten (10) trading days ending on the third trading day prior to the date on which notice of exercise
of the Warrant is sent to the Warrant Agent; or

 

(d)
as provided in Section 7.4 hereof.

 

    4

     

    

 

3.3.2 Issuance
of Shares of Common Stock on Exercise. As soon as practicable after the exercise of any Warrant and the clearance of the funds
in payment of the Warrant Price (if payment is pursuant to subsection 3.3.1(a)), the Company shall issue to the Registered
Holder of such Warrant a book-entry position or certificate, as applicable, for the number of full shares of Common Stock to which
he, she or it is entitled, registered in such name or names as may be directed by him, her or it, and if such Warrant shall not
have been exercised in full, a new book-entry position or countersigned Warrant, as applicable, for the number of shares as to
which such Warrant shall not have been exercised. Notwithstanding the foregoing, the Company shall not be obligated to deliver
any shares of Common Stock pursuant to the exercise of a Warrant and shall have no obligation to settle such Warrant exercise unless
a registration statement under the Securities Act with respect to the shares of Common Stock underlying the Public Warrants is
then effective and a prospectus relating thereto is current, subject to the Company’s satisfying its obligations under Section
7.4. No Warrant shall be exercisable and the Company shall not be obligated to issue shares of Common Stock upon exercise of
a Warrant unless the Common Stock issuable upon such Warrant exercise has been registered, qualified or deemed to be exempt under
the securities laws of the state of residence of the Registered Holder of the Warrants. In the event that the conditions in the
two immediately preceding sentences are not satisfied with respect to a Warrant, the holder of such Warrant shall not be entitled
to exercise such Warrant and such Warrant may have no value and expire worthless, in which case the purchaser of a Unit containing
such Public Warrants shall have paid the full purchase price for the Unit solely for the shares of Common Stock underlying such
Unit. Subject to Section 4.6 of this Agreement, a Registered Holder of Warrants may exercise its Warrants only
for a whole number of shares of Common Stock. In no event will the Company be required to net cash settle the Warrant exercise.
The Company may require holders of Public Warrants to settle the Warrant on a “cashless basis” pursuant to Section
7.4. If, by reason of any exercise of warrants on a “cashless basis”, the holder of any Warrant would be entitled,
upon the exercise of such Warrant, to receive a fractional interest in a share, the Company shall round down to the nearest whole
number, the number of shares to be issued to such holder. 

 

3.3.3 Valid
Issuance. All shares of Common Stock issued upon the proper exercise of a Warrant in conformity with this Agreement shall be
validly issued, fully paid and nonassessable.

 

3.3.4 Date
of Issuance. Each person in whose name any book-entry position or certificate, as applicable, for shares of Common Stock is
issued shall for all purposes be deemed to have become the holder of record of such shares of Common Stock on the date on which
the Warrant, or book-entry position representing such Warrant, was surrendered and payment of the Warrant Price was made, irrespective
of the date of delivery of such certificate in the case of a certificated Warrant, except that, if the date of such surrender and
payment is a date when the share transfer books of the Company or book-entry system of the Warrant Agent are closed, such person
shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the share
transfer books or book-entry system are open.

 

3.3.5 Maximum
Percentage. A holder of a Warrant may notify the Company in writing in the event it elects to be subject to the provisions
contained in this subsection 3.3.5; however, no holder of a Warrant shall be subject to this subsection
3.3.5 unless he, she or it makes such election. If the election is made by a holder, the Warrant Agent shall not effect
the exercise of the holder’s Warrant, and such holder shall 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% (the “Maximum Percentage”) of the shares of
Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate
number of shares of Common Stock beneficially owned by such person and its affiliates shall include the number of shares of Common
Stock issuable upon exercise of the Warrant with respect to which the determination of such sentence is being made, but shall exclude
shares of Common Stock that would be issuable upon (x) exercise of the remaining, unexercised portion of the Warrant beneficially
owned by such person and its affiliates and (y) exercise or conversion of the unexercised or unconverted portion of any other securities
of the Company beneficially owned by such person and its affiliates (including, without limitation, any convertible notes or convertible
preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except
as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance
with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For purposes
of the Warrant, in determining the number of outstanding shares of Common Stock, the holder may rely on the number of outstanding
shares of Common Stock as reflected in (1) the Company’s most recent annual report on Form 10-K, quarterly report on Form
10-Q, current report on Form 8-K or other public filing with the Commission as the case may be, (2) a more recent public announcement
by the Company or (3) any other notice by the Company or Continental Stock Transfer & Trust Company (the “Transfer Agent”)
setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written request of the holder
of the Warrant, the Company shall, within two (2) Business Days, confirm orally and in writing to such holder the number of shares
of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving
effect to the conversion or exercise of equity securities of the Company by the holder and its affiliates since the date as of
which such number of outstanding shares of Common Stock was reported. By written notice to the Company, the holder of a Warrant
may from time to time increase or decrease the Maximum Percentage applicable to such holder to any other percentage specified in
such notice; provided, however, that any such increase shall not be effective until the sixty-first (61st)
day after such notice is delivered to the Company.

4. Adjustments.

 

4.1 Stock
Dividends.

 

4.1.1 Split-Ups.
If after the date hereof, and subject to the provisions of Section 4.6 below, the number of outstanding shares
of Common Stock is increased by a stock dividend payable in shares of Common Stock, or by a split-up of shares of 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
Common Stock issuable on exercise of each Warrant shall be increased in proportion to such increase in the outstanding shares of
Common Stock. A rights offering to holders of the Common Stock entitling holders to purchase shares of Common Stock at a price
less than the “Fair Market Value” (as defined below) shall be deemed a stock dividend of a number of shares of Common
Stock equal to the product of (i) the number of shares of 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 the Common Stock) multiplied
by (ii) one (1) minus the quotient of (x) the price per share of Common Stock paid in such rights offering divided by (y) the Fair
Market Value. For purposes of this subsection 4.1.1, (i) if the rights offering is for securities convertible into
or exercisable for Common Stock, in determining the price payable for Common Stock, there shall 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 the Common Stock as reported during the ten (10) trading day period ending on the trading
day prior to the first date on which the shares of Common Stock trade on the applicable exchange or in the applicable market, regular
way, without the right to receive such rights.

 

4.1.2 Extraordinary
Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, shall pay a dividend or make a distribution
in cash, securities or other assets to the holders of the Common Stock on account of such shares of Common Stock (or other shares
of the Company’s capital stock into which the Warrants are convertible), other than (a) as described in subsection
4.1.1 above, (b) Ordinary Cash Dividends (as defined below), (c) to satisfy the redemption rights of the holders of the
Common Stock in connection with a proposed initial Business Combination, (d) as a result of the repurchase of shares of Common
Stock by the Company if a proposed initial Business Combination is presented to the shareholders of the Company for approval or
(e) in connection with the Company’s liquidation and the distribution of its assets upon its failure to consummate a Business
Combination (any such non-excluded event being referred to herein as an “Extraordinary Dividend”), then
the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the amount
of cash and/or the fair market value (as determined by the Board, in good faith) of any securities or other assets paid on each
share of Common Stock in respect of such Extraordinary Dividend. For purposes of this subsection 4.1.2, “Ordinary
Cash Dividends” means any cash dividend or cash distribution which, when combined on a per share basis, with the
per share amounts of all other cash dividends and cash distributions paid on the Common Stock during the 365-day period ending
on the date of declaration of such dividend or distribution (as adjusted to appropriately reflect any of the events referred to
in other subsections of this Section 4 and excluding cash dividends or cash distributions that resulted in an
adjustment to the Warrant Price or to the number of shares of Common Stock issuable on exercise of each Warrant) does not exceed
$0.50 (being 5% of the offering price of the Units in the Offering).

 

4.2 Aggregation
of Shares. If after the date hereof, and subject to the provisions of Section 4.6 hereof, the number of outstanding
shares of Common Stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of 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 Common Stock issuable on exercise of each Warrant shall be decreased in proportion to
such decrease in outstanding shares of Common Stock.

 

    6

     

    

 

4.3 Adjustments
in Exercise Price. Whenever the number of shares of Common Stock purchasable upon the exercise of the Warrants is adjusted,
as provided in subsection 4.1.1 or 4.2 above, the Warrant Price shall be adjusted (to the nearest
cent) by multiplying such Warrant Price immediately prior to such adjustment by a fraction (x) the numerator of which shall be
the number of shares of Common Stock purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y)
the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter. 

 

4.4 Replacement
of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares of Common
Stock (other than a change under subsections 4.1.1 or 4.1.2 or Section 4.2hereof
or that solely affects the par value of such shares of Common Stock), or in the case of any merger or consolidation of the Company
with or into another corporation (other than a consolidation or merger in which the Company is the continuing corporation and that
does not result in any reclassification or reorganization of the 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 the Company as an entirety or substantially as
an entirety in connection with which the Company is dissolved, the holders of the Warrants shall 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 Common Stock
of the Company 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 his, her or its Warrant(s) immediately prior to such event (the “Alternative
Issuance” ); provided, however, that (i) if the holders of the Common Stock were entitled
to exercise a right of election as to the kind or amount of securities, cash or other assets receivable upon such consolidation
or merger, then the kind and amount of securities, cash or other assets constituting the Alternative Issuance for which each Warrant
shall become exercisable shall be deemed to be the weighted average of the kind and amount received per share by the holders of
the Common Stock in such consolidation or merger that affirmatively make such election, and (ii) if a tender, exchange or redemption
offer shall have been made to and accepted by the holders of the Common Stock (other than a tender, exchange or redemption offer
made by the Company in connection with redemption rights held by shareholders of the Company as provided for in the Company’s
amended and restated certificate of incorporation or as a result of the repurchase of shares of Common Stock by the Company if
a proposed initial Business Combination is presented to the shareholders of the Company for approval) under circumstances in which,
upon completion of such tender or exchange offer, the maker thereof, together with members of any group (within the meaning of
Rule 13d-5(b)(1) under the Exchange Act) of which such maker is a part, and together with any affiliate or associate of such maker
(within the meaning of Rule 12b-2 under the Exchange Act) and any members of any such group of which any such affiliate or associate
is a part, own beneficially (within the meaning of Rule 13d-3 under the Exchange Act) more than 50% of the outstanding shares of
Common Stock, the holder of a Warrant shall be entitled to receive as the Alternative Issuance, the highest amount of cash, securities
or other property to which such holder would actually have been entitled as a shareholder if such Warrant holder had exercised
the Warrant prior to the expiration of such tender or exchange offer, accepted such offer and all of the Common Stock held by such
holder had been purchased pursuant to such tender or exchange offer, subject to adjustments (from and after the consummation of
such tender or exchange offer) as nearly equivalent as possible to the adjustments provided for in this Section 4; provided, further,
that if less than 70% of the consideration receivable by the holders of the Common Stock in the applicable event is payable in
the form of 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 properly exercises the Warrant within thirty (30) days following the public disclosure of the consummation of such applicable
event by the Company pursuant to a Current Report on Form 8-K filed with the SEC, the Warrant Price shall be reduced by an amount
(in dollars) equal to the difference of (i) the Warrant Price in effect prior to such reduction minus (ii) (A) the Per Share Consideration
(as defined below) (but in no event less than zero) minus (B) the Black-Scholes Warrant Value (as defined below). The “Black-Scholes
Warrant Value” means the value of a Warrant immediately prior to the consummation of the applicable event based on the Black-Scholes
Warrant Model for a Capped American Call on Bloomberg Financial Markets (“Bloomberg”). For purposes of calculating
such amount, (1) Section 6 of this Agreement shall be taken into account, (2) the price of each share of Common
Stock shall be the volume weighted average price of the Common Stock as reported during the ten (10) trading day period ending
on the trading day prior to the effective date of the applicable event, (3) the assumed volatility shall be the 90 day volatility
obtained from the HVT function on Bloomberg determined as of the trading day immediately prior to the day of the announcement of
the applicable event , and (4) the assumed risk-free interest rate shall correspond to the U.S. Treasury rate for a period equal
to the remaining term of the Warrant. “Per Share Consideration” means (i) if the consideration paid to holders of the
Common Stock consists exclusively of cash, the amount of such cash per share of Common Stock, and (ii) in all other cases, the
volume weighted average price of the Common Stock as reported during the ten (10) trading day period ending on the trading day
prior to the effective date of the applicable event. If any reclassification or reorganization also results in a change in shares
of Common Stock covered by subsection 4.1.1, then such adjustment shall be made pursuant to subsection 4.1.1 or Sections
4.2, 4.3 and this Section 4.4. The provisions of this Section 4.4 shall similarly
apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers. In no event will the
Warrant Price be reduced to less than the par value per share issuable upon exercise of such Warrant.

4.5 Notices
of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares issuable upon exercise of a Warrant,
the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such
adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of a Warrant,
setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence
of any event specified in Sections 4.1, 4.2, 4.3 or 4.4, the Company shall
give written notice of the occurrence of such event to each holder of a Warrant, at the last address set forth for such holder
in the Warrant Register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein,
shall not affect the legality or validity of such event. 

 

4.6 No
Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue fractional
shares upon the exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4, the holder of
any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share, the Company shall,
upon such exercise, round down to the nearest whole number the number of shares of Common Stock to be issued to such holder.

 

4.7 Form
of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and Warrants
issued after such adjustment may state the same Warrant Price and the same number of shares as is stated in the Warrants initially
issued pursuant to this Agreement; provided, however, that the Company may at any time in its sole discretion
make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and
any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may
be in the form as so changed.

 

4.8 Other
Events. In case any event shall occur affecting the Company as to which none of the provisions of preceding subsections of
this Section 4 are strictly applicable, but which would require an adjustment to the terms of the Warrants in
order to (i) avoid an adverse impact on the Warrants and (ii) effectuate the intent and purpose of this Section 4,
then, in each such case, the Company shall appoint a firm of independent public accountants, investment banking or other appraisal
firm of recognized national standing, which shall give its opinion as to whether or not any adjustment to the rights represented
by the Warrants is necessary to effectuate the intent and purpose of this Section 4 and, if they determine that
an adjustment is necessary, the terms of such adjustment. The Company shall adjust the terms of the Warrants in a manner that is
consistent with any adjustment recommended in such opinion.

 

5. Transfer
and Exchange of Warrants.

 

5.1 Registration
of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant upon the Warrant
Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly guaranteed and accompanied by
appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal aggregate number of Warrants
shall be issued and the old Warrant shall be cancelled by the Warrant Agent. The Warrants so cancelled shall be delivered by the
Warrant Agent to the Company from time to time upon request.

 

5.2 Procedure
for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or
transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered
Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however,
that in the event that a Warrant surrendered for transfer bears a restrictive legend (as in the case of the Private Placement Warrants),
the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange thereof until the Warrant Agent has received
an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also
bear a restrictive legend.

 

    8

     

    

 

5.3 Fractional
Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which shall result in
the issuance of a warrant certificate or book-entry position for a fraction of a warrant.

 

5.4 Service
Charges. No service charge shall be made for any exchange or registration of transfer of Warrants.

 

5.5 Warrant
Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the
terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company,
whenever required by the Warrant Agent, shall supply the Warrant Agent with Warrants duly executed on behalf of the Company for
such purpose.

 

5.6 Transfer
of Warrants. Prior to the Detachment Date, the Public Warrants may be transferred or exchanged only together with the Unit
in which such Warrant is included, and only for the purpose of effecting, or in conjunction with, a transfer or exchange of such
Unit. Furthermore, each transfer of a Unit on the register relating to such Units shall operate also to transfer the Warrants included
in such Unit. Notwithstanding the foregoing, the provisions of this Section 5.6 shall have no effect on any transfer
of Warrants on and after the Detachment Date.

 

6. Redemption.

 

6.1 Redemption.
Subject to Section 6.4 hereof, not less than all of the outstanding Warrants may be redeemed, at the option of
the Company, at any time while they are exercisable and prior to their expiration, at the office of the Warrant Agent, upon notice
to the Registered Holders of the Warrants, as described in Section 6.2 below, at the price of $0.01 per Warrant
(the “Redemption Price”), provided that the last sales price of the Common Stock reported has been at
least $21.00 per share (subject to adjustment in compliance with Section 4 hereof), on each of twenty
(20) trading days within the thirty (30) trading-day period ending on the third Business Day prior to the date on which notice
of the redemption is given and provided that there is an effective registration statement covering the shares of Common Stock issuable
upon exercise of the Warrants, and a current prospectus relating thereto, available throughout the 30-day Redemption Period (as
defined in Section 6.2 below) or the Company has elected to require the exercise of the Warrants on a “cashless
basis” pursuant to subsection 3.3.1.

 

6.2 Date
Fixed for, and Notice of, Redemption. In the event that the Company elects to redeem all of the Warrants, the Company shall
fix a date for the redemption (the “Redemption Date”). Notice of redemption shall be mailed by first
class mail, postage prepaid, by the Company not less than thirty (30) days prior to the Redemption Date (such 30-day period, the
“Redemption Period”) to the Registered Holders of the Warrants to be redeemed at their last addresses
as they shall appear on the registration books. Any notice mailed in the manner herein provided shall be conclusively presumed
to have been duly given whether or not the Registered Holder received such notice.

 

6.3 Exercise
After Notice of Redemption. The Warrants may be exercised, for cash (or on a “cashless basis” in accordance with subsection
3.3.1(b) of this Agreement) at any time after notice of redemption shall have been given by the Company pursuant to Section
6.2 hereof and prior to the Redemption Date. In the event that the Company determines to require all holders of Warrants
to exercise their Warrants on a “cashless basis” pursuant to subsection 3.3.1, the notice of redemption
shall contain the information necessary to calculate the number of shares of Common Stock to be received upon exercise of the Warrants,
including the “Fair Market Value” (as such term is defined in subsection 3.3.1(b) hereof) in such
case. On and after the Redemption Date, the record holder of the Warrants shall have no further rights except to receive, upon
surrender of the Warrants, the Redemption Price.

 

6.4 Exclusion
of Private Placement Warrants. The Company agrees that the redemption rights provided in this Section 6 shall
not apply to the Private Placement Warrants if at the time of the redemption such Private Placement Warrants continue to be held
by any Sponsor or its Permitted Transferees. However, once such Private Placement Warrants are transferred (other than
to Permitted Transferees under subsection 2.5), the Company may redeem the Private Placement Warrants, provided that
the criteria for redemption are met, including the opportunity of the holder of such Private Placement Warrants to exercise the
Private Placement Warrants prior to redemption pursuant to Section 6.3. Private Placement Warrants that are transferred
to persons other than Permitted Transferees shall upon such transfer cease to be Private Placement Warrants and shall become Public
Warrants under this Agreement.

 

    9

     

    

 

7. Other
Provisions Relating to Rights of Holders of Warrants.

 

7.1 No
Rights as Shareholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a shareholder of the
Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights
to vote or to consent or to receive notice as shareholders in respect of the meetings of shareholders or the election of directors
of the Company or any other matter.

 

7.2 Lost,
Stolen, Mutilated, or Destroyed Warrants. If any Warrant is lost, stolen, mutilated, or destroyed, the Company and the Warrant
Agent may on such terms as to indemnity or otherwise as they may in their discretion impose (which shall, in the case of a mutilated
Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor, and date as the Warrant so lost, stolen,
mutilated, or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not
the allegedly lost, stolen, mutilated, or destroyed Warrant shall be at any time enforceable by anyone.

 

7.3 Reservation
of Common Stock. The Company shall at all times reserve and keep available a number of its authorized but unissued shares of
Common Stock that shall be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement.

 

7.4 Registration
of Common Stock; Cashless Exercise at Company’s Option.

 

7.4.1 Registration
of the Common Stock. The Company agrees that as soon as practicable, but in no event later than thirty (30) days after the
closing of its initial Business Combination, it shall use its best efforts to file with the Commission a registration statement
for the registration, under the Securities Act of 1933, as amended (the “Securities Act’), of the shares of
Common Stock issuable upon exercise of the Warrants. The Company shall use its best efforts to cause the same to become effective
and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration
of the Warrants in accordance with the provisions of this Agreement. If any such registration statement has not been declared effective
by the 90th day following the closing of the Business Combination, holders of the Warrants shall have the right, during the period
beginning on the 91st day after the closing of the Business Combination and ending upon such registration statement being declared
effective by the Commission, and during any other period when the Company shall fail to have maintained an effective registration
statement covering the shares of Common Stock issuable upon exercise of the Warrants, to exercise such Warrants on a “cashless
basis,” by exchanging the Warrants (in accordance with Section 3(a)(9) of the Securities Act or another exemption) for that
number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common Stock
underlying the Warrants, multiplied by the difference between the Warrant Price and the “Fair Market Value” (as defined
below) by (y) the Fair Market Value. Solely for purposes of this subsection 7.4.1, “Fair Market Value”
shall mean the volume weighted average price of the Common Stock as reported during the ten (10) trading day period ending on the
trading day prior to the date that notice of exercise is received by the Warrant Agent from the holder of such Warrants or its
securities broker or intermediary. The date that notice of cashless exercise is received by the Warrant Agent shall be conclusively
determined by the Warrant Agent. In connection with the “cashless exercise” of a Public Warrant, the Company shall,
upon request, provide the Warrant Agent with an opinion of counsel for the Company (which shall be an outside law firm with securities
law experience) stating that (i) the exercise of the Warrants on a cashless basis in accordance with this subsection 7.4.1 is
not required to be registered under the Securities Act and (ii) the shares of Common Stock issued upon such exercise shall be freely
tradable under United States federal securities laws by anyone who is not an affiliate (as such term is defined in Rule 144 under
the Securities Act) of the Company and, accordingly, shall not be required to bear a restrictive legend. Except as provided in subsection
7.4.2, for the avoidance of any doubt, unless and until all of the Warrants have been exercised, the Company shall continue
to be obligated to comply with its registration obligations under the first three sentences of this subsection 7.4.1.

 

    10

     

    

 

7.4.2 Cashless
Exercise at Company’s Option. If the Common Stock is at the time of any exercise of a Warrant not listed on a national
securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1) of the Securities
Act, the Company may, at its option, (i) require holders of Public Warrants who exercise Public Warrants to exercise such Public
Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act as described in subsection
7.4.1 and (ii) in the event the Company so elects, the Company shall not be required to file or maintain in effect a registration
statement for the registration, under the Securities Act, of the Common Stock issuable upon exercise of the Warrants, notwithstanding
anything in this Agreement to the contrary. If the Company does not elect at the time of exercise to require a holder of Public
Warrants who exercises Public Warrants to exercise such Public Warrants on a “cashless basis,” it agrees to use its
best efforts to register or qualify for sale the Common Stock issuable upon exercise of the Public Warrant under the blue sky laws
of the state of residence in those states in which the Warrants were initially offered by the Company of the exercising Public
Warrant holder to the extent an exemption is not available.

 

8. Concerning
the Warrant Agent and Other Matters.

 

8.1 Payment
of Taxes. The Company shall from time to time promptly pay all taxes and charges that may be imposed upon the Company or the
Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise of the Warrants, but the Company
shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares.

 

8.2 Resignation,
Consolidation, or Merger of Warrant Agent.

 

8.2.1 Appointment
of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged
from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the
office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint in writing
a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of
thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder
of a Warrant (who shall, with such notice, submit his Warrant for inspection by the Company), then the holder of any Warrant may
apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor Warrant Agent
at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation
organized and existing under the laws of the State of New York, in good standing and having its principal office in the Borough
of Manhattan, City and State of New York, and authorized under such laws to exercise corporate trust powers and subject to supervision
or examination by federal or state authority. After appointment, any successor Warrant Agent shall be vested with all the authority,
powers, rights, immunities, duties, and obligations of its predecessor Warrant Agent with like effect as if originally named as
Warrant Agent hereunder, without any further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor
Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent
all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent
the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting
in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties, and obligations.

 

8.2.2 Notice
of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof
to the predecessor Warrant Agent and the Transfer Agent for the Common Stock not later than the effective date of any such appointment.

 

8.2.3 Merger
or Consolidation of Warrant Agent. Any corporation into which the Warrant Agent may be merged or with which it may be consolidated
or any corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor
Warrant Agent under this Agreement without any further act.

 

8.3 Fees
and Expenses of Warrant Agent.

 

8.3.1 Remuneration.
The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent hereunder and shall,
pursuant to its obligations under this Agreement, reimburse the Warrant Agent upon demand for all expenditures that the Warrant
Agent may reasonably incur in the execution of its duties hereunder.

 

    11

     

    

 

8.3.2 Further
Assurances. The Company agrees to perform, execute, acknowledge, and deliver or cause to be performed, executed, acknowledged,
and delivered all such further and other acts, instruments, and assurances as may reasonably be required by the Warrant Agent for
the carrying out or performing of the provisions of this Agreement.

 

8.4 Liability
of Warrant Agent.

 

8.4.1 Reliance
on Company Statement. Whenever in the performance of its duties under this Agreement, the Warrant Agent shall deem it necessary
or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder,
such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively
proved and established by a statement signed by the President, Chief Executive Officer or Chairman of the Board of the Company
and delivered to the Warrant Agent. The Warrant Agent may rely upon such statement for any action taken or suffered in good faith
by it pursuant to the provisions of this Agreement.

 

8.4.2 Indemnity.
The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct or bad faith. The Company agrees
to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, costs and reasonable
counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement, except as a result of the Warrant
Agent’s gross negligence, willful misconduct or bad faith.

 

8.4.3 Exclusions.
The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the validity or
execution of any Warrant (except its countersignature thereof). The Warrant Agent shall not be responsible for any breach by the
Company of any covenant or condition contained in this Agreement or in any Warrant. The Warrant Agent shall not be responsible
to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method,
or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall
it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of
Common Stock to be issued pursuant to this Agreement or any Warrant or as to whether any shares of Common Stock shall, when issued,
be valid and fully paid and nonassessable.

 

8.5 Acceptance
of Agency. The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon the
terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Warrants exercised
and concurrently account for, and pay to the Company, all monies received by the Warrant Agent for the purchase of shares of Common
Stock through the exercise of the Warrants.

 

8.6 Waiver.
The Warrant Agent has no right of set-off or any other right, title, interest or claim of any kind (“Claim”)
in, or to any distribution of, the Trust Account (as defined in that certain Investment Management Trust Agreement, dated as of
the date hereof, by and between the Company and the Warrant Agent as trustee thereunder) and hereby agrees not to seek recourse,
reimbursement, payment or satisfaction for any Claim against the Trust Account for any reason whatsoever. The Warrant Agent hereby
waives any and all Claims against the Trust Account and any and all rights to seek access to the Trust Account.

 

9. Miscellaneous

All the covenants and provisions of this Agreement by or for the benefit of the Company or the Warrant Agent shall bind and inure
to the benefit of their respective successors and assigns.

by the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application
of the substantive laws of another jurisdiction. The Company hereby agrees that any action, proceeding or claim against it arising
out of or relating in any way to this Agreement shall 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 irrevocably submits to such jurisdiction, which jurisdiction shall
be exclusive. The Company hereby waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient
forum.

 

9.4 Persons
Having Rights under this Agreement. Nothing in this Agreement shall be construed to confer upon, or give to, any person or
corporation other than the parties hereto and the Registered Holders of the Warrants any right, remedy, or claim under or by reason
of this Agreement or of any covenant, condition, stipulation, promise, or agreement hereof. All covenants, conditions, stipulations,
promises, and agreements contained in this Agreement shall be for the sole and exclusive benefit of the parties hereto and their
successors and assigns and of the Registered Holders of the Warrants.

 

9.5 Examination

Agent in the Borough of Manhattan, City and State of New York, for inspection by the Registered Holder of any Warrant. The Warrant
Agent may require any such holder to submit his Warrant for inspection by it.

purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

to increase the Warrant Price or shorten the Exercise Period and any amendment to the terms of only the Private Placement Warrants,
shall require the vote or written consent of the Registered Holders of 65% of the then outstanding Public Warrants. Notwithstanding

3.1 and 3.2, respectively, without the consent of the Registered Holders.

 

9.9 Severability.
This Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof shall not affect

as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable.

INVESTMENT
MANAGEMENT TRUST AGREEMENT

 

This
Investment Management Trust Agreement (this “Agreement”) is made effective as of August 18, 2016 by
and between Stellar Acquisition III Inc., a Marshall Islands corporation (the “Company”), and Continental
Stock Transfer & Trust Company, a New York corporation (the “Trustee”).

 

WHEREAS,
the Company’s registration statement on Form S-1, No. 333-212377 (the “Registration Statement”)
and prospectus (the “Prospectus”) for the initial public offering of the Company’s units (the
“Units”), each of which consists of one share of the Company’s common stock, par value $0.0001
per share (the “Common Stock”), and one warrant, each warrant entitling the holder thereof to purchase
one share of Common Stock (such initial public offering hereinafter referred to as the “Offering”),
has been declared effective as of the date hereof by the U.S. Securities and Exchange Commission; and

 

WHEREAS,
the Company has entered into an Underwriting Agreement with Maxim Group LLC as representative of the several underwriters (the
“Underwriters”) named therein (the “Underwriting Agreement”); and

 

WHEREAS,
if a Business Combination is not consummated within the initial 12 month period following the closing of the Offering, the Company’s
sponsors may extend such period by three three-month periods, up to a maximum of 21 months in the aggregate, by depositing $379,167
(or $436,042 if the Underwriters’ over-allotment option is exercised in full) into the Trust Account no later than the 12
month anniversary of the Offering, the 15 month anniversary of the Offering, or the 18 month anniversary of the Offering (each,
an “Applicable Deadline”) for each three month extension (each, an “Extension”),
in exchange for which they will receive promissory notes (unless accrued or withdrawn interest is applied pursuant to the terms
hereof); and

 

WHEREAS,
as described in the Registration Statement, $66,300,000 of the gross proceeds of the Offering and sale of the Private Placement
Warrants (as defined in the Underwriting Agreement) (or $76,245,000 if the Underwriters’ over-allotment option is exercised
in full, plus any amount eventually deposited on account of any Extension) will be delivered to the Trustee to be deposited and
held in a segregated trust account located in the United States (the “Trust Account”) for the benefit
of the Company and the holders of the Common Stock included in the Units issued in the Offering as hereinafter provided (the amount
to be delivered to the Trustee (and any interest subsequently earned thereon), including the proceeds from any loans in connection
with an Extension, if any, is referred to herein as the “Property,” the stockholders for whose
benefit the Trustee shall hold the Property will be referred to as the “Public Stockholders,” and the
Public Stockholders and the Company will be referred to together as the “Beneficiaries”); and

 

WHEREAS,
pursuant to the Underwriting Agreement, a portion of the Property equal to $1,625,000, or $1,868,750 if the Underwriters’
over-allotment option is exercised in full (in each case subject to reduction as set forth therein), is attributable to deferred
underwriting discounts and commissions that may be payable by the Company to the Underwriters upon the consummation of the Business
Combination (as defined below) (the “Deferred Discount”); and

 

WHEREAS,
the Company and the Trustee desire to enter into this Agreement to set forth the terms and conditions pursuant to which the Trustee
shall hold the Property.

 

     

     

    

 

NOW
THEREFORE, IT IS AGREED:

 

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

 

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

 

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

 

(c)

(d)
Collect and receive, when due, all interest or other income arising from the Property, which shall become part of the “Property,”
as such term is used herein;

 

(e)
Promptly notify the Company and Maxim Group LLC of all communications received by the Trustee with respect to any Property requiring

obligation to loan the Company money in connection with an extension), which amount shall be delivered directly to the Company
by electronic funds transfer or other method of prompt payment, and the Company shall forward such payment to the relevant taxing
authority; provided, however, that to the extent there is not sufficient cash in the Trust Account to
pay such tax obligation, the Trustee shall liquidate such assets held in the Trust Account as shall be designated by the Company
in writing to make such distribution; so long as there is no reduction in the principal amount initially deposited in the Trust

Executive Officer or Chief Financial Officer. In addition, except with respect to its duties under Sections 1(i), 1(j) and

Subject to Section 4 hereof, hold the Trustee harmless and indemnify the Trustee from and against any and all expenses, including
reasonable counsel fees and disbursements, or losses suffered by the Trustee in connection with any action taken by it hereunder
and in connection with any action, suit or other proceeding brought against the Trustee involving any claim, or in connection
with any claim or demand, which in any way arises out of or relates to this Agreement, the services of the Trustee hereunder,
or the Property or any interest earned on the Property, except for expenses and losses resulting from the Trustee’s gross
negligence, fraud or willful misconduct. Promptly after the receipt by the Trustee of notice of demand or claim or the commencement
of any action, suit or proceeding, pursuant to which the Trustee intends to seek indemnification under this Section 2(b),
it shall notify the Company in writing of such claim (hereinafter referred to as the “Indemnified Claim”).

the Trustee shall obtain the consent of the Company with respect to the selection of counsel, which consent shall not be unreasonably
withheld. The Trustee may not agree to settle any Indemnified Claim without the prior written consent of the Company, which such
consent shall not be unreasonably withheld. The Company may participate in such action with its own counsel;

 

    	 	3

Property shall not be used to pay such fees unless and until it is distributed to the Company pursuant to Sections 1(i) through 1(j) hereof.
The Company shall pay the Trustee the initial acceptance fee and the first annual administration fee at the consummation of the
Offering. The Trustee shall refund to the Company the monthly fee (on a pro rata basis) with respect to any period after the liquidation
of the Trust Account. The Company shall not be responsible for any other fees or charges of the Trustee except as set forth in
this Section 2(c) and as may be provided in Section 2(b) hereof;

 

(d)
In connection with any vote of the Company’s stockholders regarding a merger, capital stock exchange, asset acquisition,
stock purchase, reorganization or similar business combination involving the Company and one or more businesses (a “Business
Combination”), provide to the Trustee an affidavit or certificate of a designated Inspector of Elections from a firm regularly
engaged in the business of soliciting proxies and/or tabulating stockholder votes for stockholder meetings verifying the vote
of the Company’s stockholders regarding such Business Combination;

shall in no event be less than $1,625,000;

action, avoid or seek to avoid the observance or performance of any of the terms of the rights of the Public Stockholders, and
will at all times in good faith carry out all of the provisions described in the Company’s amended and restated articles
of incorporation, herein and in any other agreement described in the Registration Statement, in each case, as of the date hereof,
and take all action as may be required to protect the rights of the Public Stockholders. For the avoidance of doubt and without
limiting the generality of the foregoing, the Company will not impair the redemption rights of the Public Stockholders as described
in its amended and restated articles of incorporation and in the Registration Statement, in each case, as of the date hereof,
through the amendment of the Company’s amended and restated articles of incorporation or any of the agreements or arrangements
described herein or otherwise, and the Company will ensure that the Public Stockholders shall at all times be granted the redemption
rights as described in the Company’s amended and restated articles of incorporation, herein and in the Registration Statement,

Public Shareholder receives a Disbursement Notice, a "Disbursement Notice Date"). Each Disbursement Notice
shall be delivered to such Public Shareholder at least two business days prior to the disbursement of any Property pursuant to

Gentlemen:

 

Pursuant
to Section 1(i) of the Investment Management Trust Agreement between Stellar Acquisition III Inc. (“Company”)
and Continental Stock Transfer & Trust Company (“Trustee”), dated as of August 18, 2016 (“Trust
Agreement”), this is to advise you that the Company has entered into an agreement with ____________ (“Target
Business”) to consummate a business combination with Target Business (“Business Combination”)
on or about [insert date]. The Company shall notify you at least forty-eight (48) hours in advance of the actual date of
the consummation of the Business Combination (“Consummation Date”). Capitalized terms used but not defined
herein shall have the meanings set forth in the Trust Agreement.

 

In
accordance with the terms of the Trust Agreement, we hereby authorize you to commence to liquidate all of the assets of the Trust
Account on [insert date], and to transfer the proceeds into the trust checking account at JP Morgan Chase Bank, N.A.
to the effect that, on the Consummation Date, all of funds held in the Trust Account will be immediately available for transfer
to the account or accounts that the Company shall direct on the Consummation Date. It is acknowledged and agreed that while the
funds are on deposit in the trust checking account at JP Morgan Chase Bank, N.A. awaiting distribution, the Company will not earn
any interest or dividends.

 

On
the Consummation Date (i) counsel for the Company shall deliver to you written notification that the Business Combination has
been consummated, or will be consummated concurrently with your transfer of funds to the accounts as directed by the Company (the
“Notification”) and (ii) the Company shall deliver to you (a) a certificate of the Chief Executive Officer,
which verifies that the Business Combination has been approved by a vote of the Company’s stockholders, if a vote is held
and (b) joint written instruction signed by the Company and Maxim Group LLC with respect to the transfer of the funds held in
the Trust Account, including payment of the Deferred Discount from the Trust Account (the “Instruction Letter”).
You are hereby directed and authorized to transfer the funds held in the Trust Account immediately upon your receipt of the Notification
and the Instruction Letter, in accordance with the terms of the Instruction Letter. In the event that certain deposits held in
the Trust Account may not be liquidated by the Consummation Date without penalty, you will notify the Company in writing of the
same and the Company shall direct you as to whether such funds should remain in the Trust Account and be distributed after the
Consummation Date to the Company. Upon the distribution of all the funds, net of any payments necessary for reasonable unreimbursed
expenses related to liquidating the Trust Account, your obligations under the Trust Agreement shall be terminated.

 

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