		2.	Shelf
                                         Registrations, DEMAND REGISTRATIONS and Piggy Back Registrations

 

(a)       Shelf
Registration.

 

(i)       Filing.
The Company shall, as soon as practicable after the date that is six months from the date of this Agreement, but in any event
within thirty (30) days after the date that is six months from the date of this Agreement, file a Registration Statement under
the Securities Act to permit the public resale of all the Registrable Securities held by the Holders from time to time as permitted
by Rule 415 under the Securities Act (or any successor or similar provision adopted by the Commission then in effect) (the “Shelf
Registration Statement”) on the terms and conditions specified in this Section 2(a) and shall use its reasonable best
efforts to cause such Shelf Registration Statement to be declared effective as soon as practicable after the filing thereof, but
in any event no later than the earlier of (i) ninety (90) days (or one hundred and twenty (120) days if the Commission notifies
the Company that it will “review” the Shelf Registration Statement) after the date that is six months from the date
of this Agreement and (ii) the tenth (10th) business day after the date the Company is notified (orally or in writing, whichever
is earlier) by the Commission that such Shelf Registration Statement will not be “reviewed” or will not be subject
to further review (such earlier date, the “Effectiveness Deadline”). The Shelf Registration Statement filed
with the Commission pursuant to this Section 2(a) shall be on Form S-3 or, if Form S-3 is not then available to the Company, on
Form S-1 or such other form of registration statement as is then available to effect a registration for resale of such Registrable
Securities, covering such Registrable Securities, and shall contain a prospectus in such form as to permit any Holder to sell
such Registrable Securities pursuant to Rule 415 under the Securities Act (or any successor or similar provision adopted by the
Commission then in effect) at any time beginning on the effective date for such Shelf Registration Statement. A Shelf Registration
Statement filed pursuant to this Section 2(a) shall provide for the resale pursuant to any method or combination of methods legally
available to, and requested by, the Holders.  As soon as practicable following the effective date of a Shelf Registration
Statement filed pursuant to this Section 2(a), but in any event within three (3) business days of such date, the Company shall
notify the Holders of the effectiveness of such Registration Statement. When effective, a Shelf Registration Statement filed pursuant
to this Section 2(a) (including the documents incorporated therein by reference) will comply as to form in all material respects
with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading
(in the case of any prospectus contained in such Shelf Registration Statement, in the light of the circumstances under which such
statement is made).

 

(ii)       Continued
Effectiveness. The Company shall use its reasonable best efforts to cause the Shelf Registration Statement to remain effective
and to be supplemented and amended to the extent necessary to ensure that such Shelf Registration Statement is available or, if
not available, that another registration statement is available, for the resale of all the Registrable Securities held by the
Holders until the earliest of (A) the date all such Registrable Securities have ceased to be Registrable Securities and (B) the
date all such Registrable Securities covered by such Shelf Registration Statement can be sold publicly without restriction or
limitation under Rule 144 under the Securities Act and without the requirement to be in compliance with Rule 144(c)(1) under the
Securities Act.

 

    	 	5	 

     

    

 

(iii)       Underwritten
Offering and Selection of Underwriters. If the Holders of at least a Majority of the then outstanding number of Registrable
Securities held by the Holders (the “Underwritten Demand Holders”) elect to dispose of Registrable Securities
under a Shelf Registration Statement or other Registration Statement pursuant to an Underwritten Offering (an “Underwritten
Offering”) of all or part of such Registrable Securities that are registered by such Shelf Registration Statement or
other Registration Statement and reasonably expect aggregate gross proceeds in excess of $50,000,000 (the “Holders’
Minimum Amount”) from such Underwritten Offering, then the Company shall, upon the written demand of such Underwritten
Demand Holder(s), enter into an underwriting agreement in a form as is customary in Underwritten Offerings of securities by the
Company with the managing underwriter or underwriters selected by the Underwritten Demand Holders and shall take all such other
reasonable actions as are requested by the managing underwriter or underwriters in order to expedite or facilitate the disposition
of such Registrable Securities; provided, however, that the Company shall have no obligation to facilitate or participate in more
than two (2) Underwritten Offerings in any twelve (12)-month period, pursuant to this Section 2(a) or Section 2(b).  In connection
with any Underwritten Offering contemplated by this Section 2(a) or Section 2(b), the underwriting agreement into which each Holder
and the Company shall enter shall contain such representations, covenants, indemnities and other rights and obligations as are
customary in underwritten offerings of securities by the Company. No Holder shall be required to make any representations or warranties
to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Holder’s
authority to enter into such underwriting agreement and to sell, and its ownership of, the securities being registered on its
behalf, its intended method of distribution, the accuracy of information provided by a Holder specifically for use in the Registration
Statement or Prospectus, and any other representation required by law; provided, that Holders other than the Underwritten
Demand Holders shall be afforded five (5) Business Days to decide to include Registrable Securities in any such Underwritten Offering
in proportion to the Registrable Securities of the Underwritten Demand Holders that are included in such Underwritten Offering;
provided further, that to the extent such other Holders wish to include additional Registrable Securities held by such
Holders in an Underwritten Offering in excess of their allotted proportion, such other Holders may request, within the same five
(5) Business Day notice period outlined above, that the Underwritten Demand Holders consider including such additional shares
as Registrable Securities.  Upon receipt of such notice, and subject to Section 2(d)(i), the Underwritten Demand Holders
may elect to include or exclude such additional Registrable Securities from the Underwritten Offering in their sole and absolute
discretion.

 

(b)       Demand
Registrations.

 

(i)       Right
to Request Registration. So long as the Company does not have an effective Shelf Registration Statement with respect to the
Registrable Securities, the Holders of at least twenty percent (20%) of the then-outstanding number of Registrable Securities
(the “Demand Holders”) may request registration under the Securities Act of all or part of their Registrable
Securities with an anticipated aggregate offering price of at least $50 million at any time and from time to time (“Demand
Registration”).

 

    	 	6	 

     

    

 

Within
seven (7) Business Days after receipt of any such request for Demand Registration, the Company shall give written notice of such
request to all other Holders of Registrable Securities, if any, and shall, subject to the provisions of Section 2(d)(i) hereof,
include in such registration the number of Registrable Securities of such Holder up to an amount in proportion to the Registrable
Securities of the Demand Holders that are to be included in the Demand Registration and with respect to which the Company has
received written requests for inclusion therein within five (5) Business Days after the receipt of the Company’s notice;
provided, that to the extent such other Holders wish to include additional Registrable Securities held by such Holders
in the Demand Registration in excess of their allotted proportion, such other Holders may request, within the same five (5) Business
Day notice period outlined above, that the Demand Holders consider including such additional shares as Registrable Securities. 
Upon receipt of such notice, and subject to Section 2(d)(i), the Demand Holders may elect to include or exclude such additional
Registrable Securities from the Underwritten Offering in their sole and absolute discretion. The Company shall use its reasonable
best efforts to file with the Commission following receipt of any such request for Demand Registration (but in no event more than
thirty (30) days following receipt of such request) one or more registration statements with respect to all such Registrable Securities
with respect to which the Company has received written requests for inclusion therein in accordance with this paragraph under
the Securities Act (the “Demand Registration Statement”). The Company shall use its reasonable best efforts
to cause such Demand Registration Statement to be declared effective by the Commission as soon as practicable after the filing
thereof. The Demand Registration Statement shall be on an appropriate form and the Registration Statement and any form of Prospectus
included therein (or Prospectus supplement relating thereto) shall reflect the plan of distribution or method of sale as the Holders
of shares registered on such Registration Statement may from time to time notify the Company. Following the receipt by the Company
of any request for Demand Registration, subject to Section 2(d)(i), all of the Registrable Securities of any Holder electing
to register Registrable Securities in accordance with this paragraph shall be included in the Demand Registration Statement without
any further action by any Holder. The Demand Holders may cause the Company to postpone or withdraw the filing or the effectiveness
of a Demand Registration at any time in their sole discretion.

 

(ii)       Restrictions
on Demand Registrations. The Company shall not be obligated to effect any Demand Registration within ninety (90) days after
the effective date of a previous Demand Registration or a previous registration under which any Holder or Holders (the “Initiating
Holders”) had piggyback rights pursuant to Section 2(c) hereof wherein the Initiating Holders were permitted to
register, and sold, at least fifty percent (50%) of the shares of Registrable Securities requested to be included therein. In
addition, the Company shall not be obligated to effect any Demand Registration after the Company has effected two (2) Demand Registrations
in any twelve (12)-month period if all such registrations effected by the Company have been declared and ordered effective.

 

(iii)       Underwritten
Offering and Selection of Underwriters. If the Underwritten Demand Holders elect to dispose of Registrable Securities under
a Demand Registration pursuant to an Underwritten Offering, then other Holders shall be afforded the right to include Registrable
Securities in any such Underwritten Offering in proportion to the Registrable Securities of the Underwritten Demand Holders that
are included in such Underwritten Offering. If any of the Registrable Securities covered by a Demand Registration hereof are to
be sold in an Underwritten Offering, then the Underwritten Demand Holders shall have the right to select the managing underwriter
or underwriters to administer any such Underwritten Offering.

 

    	 	7	 

     

    

 

(iv)       Effective
Period of Demand Registrations. After any Demand Registration Statement filed pursuant to this Agreement has become effective,
the Company shall use its reasonable best efforts to keep such Demand Registration Statement effective for a period equal to one
hundred eighty (180) days from the date on which the Commission declares such Demand Registration Statement effective (or if such
Demand Registration Statement is not effective during any period within such one hundred eighty (180) days, such 180-day period
shall be extended by the number of days during such period when such Demand Registration Statement is not effective), or such
shorter period that shall terminate when all of the Registrable Securities covered by such Demand Registration Statement have
been sold pursuant to such Demand Registration. If the Company shall withdraw or reduce the number of shares of Registrable Securities
that is subject to any Demand Registration pursuant to Section 2(d)(i) (a “Withdrawn Demand Registration”),
the Initiating Holders of the Registrable Securities remaining unsold and originally covered by such Withdrawn Demand Registration
shall be entitled to a replacement Demand Registration that (subject to the provisions of this Section 2(b)) the Company
shall use its reasonable best efforts to keep effective for a period commencing on the effective date of such Demand Registration
and ending on the earlier to occur of the date (i) that is one hundred eighty (180) days from the effective date of such Demand
Registration and (ii) on which all of the Registrable Securities covered by such Demand Registration have been sold. Such additional
Demand Registration otherwise shall be subject to all of the provisions of this Agreement.

 

(c)       Piggyback
Registrations.

 

(i)       Right
to Piggyback. Whenever the Company proposes to register any of its Common Stock under the Securities Act (other than a registration
statement on Form S-8 or on Form S-4 or any similar successor forms thereto), whether for its own account or for the account of
one or more stockholders of the Company, and the registration form to be used may be used for any registration of Registrable
Securities (a “Piggyback Registration”), the Company shall give prompt (but in no event less than ten (10)
days before the anticipated filing date of such registration statement) written notice to all Holders of its intention to effect
such a registration, which notice shall (A) describe the amount and type of securities to be included in such offering, the intended
method of distribution, and the name of the proposed managing underwriter, if any, in such offering, and (B) offer to all Holders
of Registrable Securities the opportunity to register the same of such number of Registrable Securities as such Holders may request
in writing within five (5) Business Days after receipt of such written notice from the Company. The Company shall, subject to
Sections 2(d)(ii) and 2(d)(iii), include in such registration all Registrable Securities with respect to which the Company
has received written requests for inclusion therein within five (5) Business Days after the receipt of the Company’s notice.
The Company may postpone or withdraw the filing or the effectiveness of a Piggyback Registration at any time in its sole discretion.

 

(ii)       Withdrawal.
Any Holder may elect to withdraw such Holder’s request for inclusion of Registrable Securities in any Piggyback Registration
by giving written notice to the Company of such request to withdraw prior to the effectiveness of the Registration Statement.
The Company (whether on its own determination or as the result of a withdrawal by Persons making a demand pursuant to written
contractual obligations) may withdraw a Registration Statement at any time prior to the effectiveness of the Registration Statement
without thereby incurring any liability to the Holders of Registrable Securities. Notwithstanding any such withdrawal, the Company
shall pay all expenses incurred by the Holders in connection with such Piggyback Registration as provided in Section 8(d).

 

    	 	8	 

     

    

 

(iii)       Selection
of Underwriters. If any of the Registrable Securities of the Holders covered by a Piggyback Registration hereof are to be
sold in an Underwritten Offering, then the Company shall have the right to select the managing underwriter or underwriters to
administer any such offering.

 

(d)       Priority.

 

(i)       Priority
on Shelf and Demand Registrations. If the managing underwriters of a requested Demand Registration or an Underwritten Offering
under a Shelf Registration Statement, advise the Company in writing that, in their opinion, the number of Registrable Securities
requested to be included in such Demand Registration Statement or Shelf Registration Statement exceeds the number that can be
sold in such offering and/or that the number of Registrable Securities proposed to be included in any such registration would
adversely affect the price per share of the Company’s equity securities to be sold in such offering (such maximum number
of securities or Registrable Securities, as applicable, the “Maximum Threshold”), the underwriting shall be
allocated among the Company and all Holders as follows: (A) first, the shares comprised of Registrable Securities, as to which
registration has been requested and is required pursuant to the registration rights hereof, based on the amount of such Common
Stock initially requested to be registered by such Holders that can be sold without exceeding the Maximum Threshold; (B) second,
to the extent that the Maximum Threshold has not been reached under the foregoing clause (A), the shares of Common Stock or other
securities that the Company desires to sell that can be sold without exceeding the Maximum Threshold; and (C) third, to the extent
the Maximum Threshold has not been reached under the foregoing clauses (A) and (B), any additional Registrable Securities of Holders
other than the Demand Holders or Underwritten Demand Holders as to which registration has been requested and that the Demand Holders
or Underwritten Demand Holders, as applicable, determine, in their sole discretion, can be sold.

 

(ii)       Priority
on Primary Registrations. If a Piggyback Registration is an underwritten primary registration on behalf of the Company, and
the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included
in such registration exceeds the Maximum Threshold, the underwriting shall be allocated among the Company and all Holders as follows:
(A) first, the shares of Common Stock or other securities that the Company desires to sell that can be sold without exceeding
the Maximum Threshold; and (B) second, to the extent that the Maximum Threshold has not been reached under the foregoing
clause (A), the shares comprised of Registrable Securities, as to which registration has been requested pursuant to the registration
rights hereof, based on the amount of such Common Stock initially requested to be registered by such Holders that can be sold
without exceeding the Maximum Threshold.

 

(iii)       Notwithstanding
the foregoing, if the Holders of at least twenty percent (20%) of the then-outstanding number of Registrable Securities wish to
engage in an underwritten block trade off of an effective Shelf Registration Statement, Demand Registration Statement or Piggyback
Registration, such Holders may notify the Company of the block trade offering on the day such offering is to commence and the
Company shall as expeditiously as possible use its reasonable best efforts to facilitate such offering (which may close as early
as three (3) Business Days after the date it commences); provided that in the case of such underwritten block trade,
only such Holders shall have a right to notice of and to participate in such offering.

 

    	 	9	 

     

    

 

(e)       For
the avoidance of doubt, no Holder may exercise its rights pursuant to this Section 2 with respect to any Registrable Securities
so long as such Holder is restricted from the transfer of such securities pursuant to that certain Lock-Up Agreement, dated as
of the date hereof, by and between the Company, NextDecade, LLC and the Holders who are party thereto.

 

		3.	Black-Out
                                         Periods

 

(a)       Notwithstanding
Section 2, and subject to the provisions of this Section 3, the Company shall be permitted, in limited circumstances,
to suspend the use, from time to time, of the Prospectus that is part of a Shelf Registration Statement (and therefore suspend
sales of the Registrable Securities under such Shelf Registration Statement), by providing written notice (a “Suspension
Notice”) to the Selling Holders’ Counsel, if any, and the Holders, for such times as the Company reasonably may
determine is necessary and advisable (but in no event for more than an aggregate of ninety (90) days in any rolling twelve (12)-month
period commencing on the date of this Agreement or more than forty-five (45) consecutive days, except as a result of a refusal
by the Commission to declare any post-effective amendment to the Shelf Registration Statement effective after the Company has
used all reasonable best efforts to cause the post-effective amendment to be declared effective by the Commission, in which case,
the Company must terminate the black-out period immediately following the effective date of the post-effective amendment) if either
of the following events shall occur: (i) a majority of the Board determines in good faith that (A) the offer or sale
of any Registrable Securities would materially impede, delay or interfere with any proposed financing, offer or sale of securities,
acquisition, corporate reorganization or other material transaction involving the Company, (B) after the advice of counsel,
the sale of Registrable Securities pursuant to the Shelf Registration Statement would require disclosure of non-public material
information not otherwise required to be disclosed under applicable law, and (C) (x) the Company has a bona fide business
purpose for preserving the confidentiality of such transaction, (y) disclosure would have a material adverse effect on the
Company or the Company’s ability to consummate such transaction, or (z) such transaction renders the Company unable
to comply with Commission requirements, in each case under circumstances that would make it impractical or inadvisable to cause
the Shelf Registration Statement (or such filings) to become effective or to promptly amend or supplement the Shelf Registration
Statement on a post-effective basis, as applicable; or (ii) a majority of the Board determines in good faith, upon the advice
of counsel, that it is in the Company’s best interest or it is required by law, rule or regulation to supplement the Shelf
Registration Statement or file a post-effective amendment to the Shelf Registration Statement in order to ensure that the Prospectus
included in the Shelf Registration Statement (1) contains the information required under Section 10(a)(3) of the Securities
Act; (2) discloses any facts or events arising after the effective date of the Shelf Registration Statement (or of the most
recent post-effective amendment) that, individually or in the aggregate, represents a fundamental change in the information set
forth therein; or (3) discloses any material information with respect to the plan of distribution that was not disclosed
in the Shelf Registration Statement or any material change to such information. Upon the occurrence of any such suspension, the
Company shall use its reasonable best efforts to cause the Shelf Registration Statement to become effective or to promptly amend
or supplement the Shelf Registration Statement on a post-effective basis or to take such action as is necessary to make resumed
use of the Shelf Registration Statement as soon as possible.

 

    	 	10	 

     

    

 

(b)       In
the case of an event that causes the Company to suspend the use of a Shelf Registration Statement as set forth in paragraph (a)
above (a “Suspension Event”), the Company shall give a Suspension Notice to the Selling Holders’ Counsel,
if any, and the Holders to suspend sales of the Registrable Securities and such Suspension Notice shall state generally the basis
for the notice and that such suspension shall continue only for so long as the Suspension Event or its effect is continuing and
the Company is using its reasonable best efforts and taking all reasonable steps to terminate suspension of the use of the Shelf
Registration Statement as promptly as possible. A Holder shall not effect any sales of the Registrable Securities pursuant to
such Shelf Registration Statement (or such filings) at any time after it has received a Suspension Notice from the Company and
prior to receipt of an End of Suspension Notice (as defined below). If so directed by the Company, each Holder will deliver to
the Company (at the expense of the Company) all copies other than permanent file copies then in such Holder’s possession
of the Prospectus covering the Registrable Securities at the time of receipt of the Suspension Notice. The Holders may recommence
effecting sales of the Registrable Securities pursuant to the Shelf Registration Statement (or such filings) following further
written notice to such effect (an “End of Suspension Notice”) from the Company, which End of Suspension Notice
shall be given by the Company to the Holders and to the Selling Holders’ Counsel, if any, promptly following the conclusion
of any Suspension Event and its effect.

 

(c)       Notwithstanding
any provision herein to the contrary, if the Company shall give a Suspension Notice with respect to any Shelf Registration Statement
pursuant to this Section 3, the Company agrees that it shall extend the period of time during which such Shelf Registration
Statement shall be maintained effective pursuant to this Agreement by the number of days during the period from the date of receipt
by the Holders of the Suspension Notice to and including the date of receipt by the Holders of the End of Suspension Notice and
provide copies of the supplemented or amended Prospectus necessary to resume sales, with respect to each Suspension Event; provided
that such period of time shall not be extended beyond the date that Common Stock covered by such Shelf Registration Statement
are no longer Registrable Securities.

(ix)       cooperate
with the selling Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities
to be sold and not bearing any restrictive legends; and enable such Registrable Securities to be in such denominations and registered

as promptly as practicable after the occurrence of such an event, use its reasonable best efforts to prepare a supplement or post-effective
amendment to the Registration Statement or the related Prospectus or any document incorporated therein by reference or file any
other required document so that, as thereafter delivered to the purchasers of the Registrable Securities, such Prospectus will
not contain at the time of such delivery any untrue statement of a material fact or omit to state a material fact necessary to

(xiii)       enter

the disposition of such Registrable Securities whether or not an underwriting agreement is entered into and whether or not the
registration is an underwritten registration:

 

(1)       make
such representations and warranties to the Holders of such Registrable Securities and the underwriters, if any, in form, substance
and scope as are customarily made by issuers to underwriters in similar Underwritten Offerings as may be reasonably requested
by them;

 

(2)       obtain

available for inspection by any underwriter participating in any disposition pursuant to a Registration Statement, Selling Holders’

corporate documents and properties or assets of the Company reasonably requested by any such Persons, and cause the respective
officers, directors, employees, and any other agents of the Company to supply all information reasonably requested by any such

to the extent reasonably practicable, to coordinate the foregoing inspection and information gathering and to not materially disrupt
the Company’s business operations;

 

    	 	14	 

     

    

 

(xv)       a

the selling Holders or the plan of distribution of Registrable Securities, as Selling Holders’ Counsel, reasonably requests;
not file any such document in a form to which any underwriter shall not have previously been advised and furnished a copy of or

unless Selling Holders’ Counsel has been advised in advance and has approved such information or change; and make the representatives
of the Company available for discussion of such document as shall be reasonably requested by the Selling Holders’ Counsel,
if any, on behalf of such Holders, Selling Holders’ Counsel or any underwriter;

distribution by such Holder of such Registrable Securities as the Company may from time to time reasonably request in writing.

 

(xx)       if

their reasonable best efforts to cooperate as reasonably requested by the underwriters in the offering, marketing or selling of
the Registrable Securities.

 

    	 	15	 

     

    

 

Each
Holder agrees that, upon receipt of any notice from the Company of the happening of any event or the discovery of any facts of
the type described in Section 4(a)(v) hereof, such Holder will forthwith discontinue disposition of Registrable Securities
pursuant to a Registration Statement relating to such Registrable Securities until such Holder’s receipt of the copies of
the supplemented or amended Prospectus contemplated by Section 4(a)(v) hereof, and, if so directed by the Company, such Holder
will deliver to the Company (at the Company’s expense) all copies in such Holder’s possession, other than permanent
file copies then in such Holder’s possession, of the Prospectus covering such Registrable Securities current at the time
of receipt of such notice.

 

		5.	Indemnification

 

(a)       Indemnification
by the Company. The Company agrees to indemnify and hold harmless each Holder, and the respective officers, directors, partners,
employees, representatives and agents of any such Person, and each Person (a “Controlling Person”), if any,
who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) any of the foregoing
Persons, as follows:

 

(i)       against
any and all loss, penalty, liability, claim, damage, judgment, suit, action, other liabilities and expenses whatsoever (“Liabilities”),
as incurred, arising out of or based on any untrue statement or alleged untrue statement of a material fact contained in any Registration
Statement (including any final, preliminary or summary Prospectus contained therein or any amendment or supplement thereto) pursuant
to which Registrable Securities were registered under the Securities Act, including all documents incorporated therein by reference,
or any other disclosure document produced by or on behalf of the Company or any of its subsidiaries including reports and other
documents filed under the Exchange Act, or the omission or alleged omission therefrom of a material fact required to be stated
therein or necessary to make the statements therein not misleading, or arising out of or based on any untrue statement or alleged
untrue statement of a material fact contained in any Prospectus (or any amendment or supplement thereto) or the omission or alleged
omission therefrom at such date of a material fact necessary in order to make the statements therein, in the light of the circumstances
under which they were made, not misleading;

 

(ii)       against
any and all Liabilities, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation
or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue
statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 5(d) below)
any such settlement is effected with the written consent of the Company; and

 

(iii)       against
any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by any indemnified party),
reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or any claim whatsoever arising out of or based upon any such untrue statement
or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under subparagraph
(i) or (ii) above; provided, however, that this indemnity agreement shall not apply to any Liabilities to the extent
arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity
with written information furnished to the Company by the Holder expressly for use in a Registration Statement (or any amendment
thereto) or any Prospectus (or any amendment or supplement thereto).

 

    	 	16	 

     

    

 

The
indemnity in this Section 5(a) shall be in addition to any liability the Company may otherwise have. Such indemnity shall remain
in full force and effect regardless of any investigation made by or on behalf of such Holder or any indemnified party and shall
survive any transfer of such securities by such Holder. The Company shall also indemnify underwriters, selling brokers, dealer
managers and similar securities industry professionals participating in the offering, their officers and directors and each Person
who controls such Persons (within the meaning of the Securities Act and the Exchange Act) to the same extent as provided above
with respect to the indemnification of the indemnified parties.

 

(b)       Indemnification
by the Holders. Each Holder severally, but not jointly, agrees to indemnify and hold harmless the Company and the other selling
Holders, and each of their respective officers, directors, partners, employees, representatives and agents, against any and all
Liabilities described in the indemnity contained in Section 5(a) hereof, as incurred, but only with respect to untrue statements
or omissions, or alleged untrue statements or omissions, made in a Registration Statement (or any amendment thereto) or any Prospectus
included therein (or any amendment or supplement thereto) in reliance upon and in conformity with written information such Holder
furnished to the Company by such Holder expressly for use in the Registration Statement (or any amendment thereto) or such Prospectus
(or any amendment or supplement thereto); provided, however, that no such Holder shall be liable for any claims
hereunder in excess of the amount of net proceeds received by such Holder from the sale of Registrable Securities pursuant to
such Registration Statement.

 

(c)       Notices
of Claims, etc. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party
of any action or proceeding commenced against it in respect of which indemnity may be sought hereunder; provided, however,
that failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the
extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may
have otherwise than on account of this indemnity agreement. An indemnifying party may participate at its own expense in the defense
of such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of
the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying party or parties be liable
for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all
indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified
parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or
proceeding by any governmental agency or body, commenced or threatened, or any claim whosoever in respect of which indemnification
or contribution could be sought under this Section 5 (whether or not the indemnified parties are actual or potential parties
thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all
liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an
admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

 

(d)       Indemnification
Payments. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party
for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated
by Section 5(a)(ii) effected without its written consent if (i) such settlement is entered into more than forty-five (45)
days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice
of the terms of such settlement at least thirty (30) days prior to such settlement being entered into and (iii) such indemnifying
party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

 

    	 	17	 

     

    

 

(e)       Contribution.
If the indemnification provided for in this Section 5 is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any Liabilities referred to therein, then each indemnifying party shall contribute to the aggregate
amount of such Liabilities incurred by such indemnified party, as incurred, in such proportion as is appropriate to reflect the
relative fault of the Company, on the one hand, and the Holders, on the other hand, in connection with the acts, statements or
omissions which resulted in such Liabilities, as well as any other relevant equitable considerations.

 

The
relative fault of the Company on the one hand and the Holders on the other hand shall be determined by reference to, among other
things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material
fact relates to information supplied by the Company or the Holders and the parties’ relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

 

The
Company and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 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 above in this Section 5. The aggregate amount of Liabilities incurred by an indemnified party and referred to above in
this Section 5 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating,
preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced
or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.
Notwithstanding the provisions of this Section 5(e), no Holder shall be liable for any claims hereunder in excess of the amount
of net proceeds received by such Holder from the sale of Registrable Securities pursuant to any such Registration Statement.

 

No
Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled
to contribution from any Person who was not guilty of such fraudulent misrepresentation.

 

For
purposes of this Section 5, each Person, if any, who controls a Holder within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act shall have the same rights to contribution as a Holder, and each director of the Company,
and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act shall have the same rights to contribution as the Company.

 

		6.	Holdback
                                         Agreement

 

(a)       Each
Holder agrees not to effect any sale, transfer, or other actual or pecuniary transfer (including heading and similar arrangements)
of any Registrable Securities or of any other equity securities of the Company, or any securities convertible into or exchangeable
or exercisable for such stock or securities, during the period beginning seven (7) days prior to, and ending ninety (90) days
after (or for such shorter period as to which the managing underwriter(s) may agree), the date of the underwriting agreement of
each Underwritten Offering made pursuant to a Registration Statement other than Registrable Securities sold pursuant to such Underwritten
Offering; and (b) the Company agrees not to effect any public sale or distribution of its equity securities (or any securities
convertible into or exchangeable or exercisable for such securities) during the seven (7) days prior to and during the ninety
(90)-day period beginning on the effective date of any underwritten Demand Registration (or for such shorter period as to which
the managing underwriter or underwriters may agree), except as part of such Demand Registration or in connection with any employee
benefit or similar plan, any dividend reinvestment plan, or a business acquisition or combination and to use all reasonable efforts
to cause each holder of at least five percent (5%) (on a fully diluted basis) of its equity securities (or any securities convertible
into or exchangeable or exercisable for such securities) which are or may be purchased from the Company at any time after the
date of this Agreement (other than in a registered offering) to agree not to effect any sale or distribution of any such securities
during such period (except as part of such Underwritten Offering, if otherwise permitted). Each Holder agrees to enter into any
agreements reasonably requested by any managing underwriter reflecting the terms of this Section 6.

		7.	Termination

 

Survival.
This Agreement and the rights of each Holder hereunder shall terminate upon the date that all of the Registrable Securities cease
to be Registrable Securities. Notwithstanding the foregoing, the obligations of the parties under Section 5 of this Agreement
shall remain in full force and effect following such time.

 

		8.	Miscellaneous

 

(a)       Covenants
Relating To Rule 144. For so long as the Company is subject to the reporting requirements of Section 13 or 15 of the
Securities Act, the Company covenants that it will file the reports required to be filed by it under the Securities Act and Section 13(a)
or 15(d) of the Exchange Act and the rules and regulations adopted by the Commission thereunder. If the Company ceases to be so
required to file such reports, the Company covenants that it will upon the request of any Holder of Registrable Securities (a)
make publicly available such information as is necessary to permit sales pursuant to Rule 144 under the Securities Act, (b) deliver
such information to a prospective purchaser as is necessary to permit sales pursuant to Rule 144A under the Securities Act and
it will take such further action as any Holder of Registrable Securities may reasonably request, and (c) take such further action
that is reasonable in the circumstances, in each case, to the extent required, from time to time, to enable such Holder to sell
its Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (i)
Rule 144 under the Securities Act, as such Rule may be amended from time to time, (ii) Rule 144A under the Securities Act, as
such rule may be amended from time to time, or (iii) any similar rules or regulations hereafter adopted by the Commission. Upon
the request of any Holder of Registrable Securities, the Company will deliver to such Holder a written statement as to whether
it has complied with such requirements and of the Securities Act and the Exchange Act (at any time after it has become subject
to the reporting requirements of the Exchange Act), a copy of the most recent annual and quarterly report(s) of the Company, and
such other reports, documents or stockholder communications of the Company, and take such further actions consistent with this
Section 8(a), as a Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing
a Holder to sell any such Registrable Securities without registration.

 

(b)       Cooperation.
The Company shall cooperate with the Holders in any sale and or transfer of Registrable Securities including by means not involving
a registration statement.

 

    	 	19	 

     

    

 

(c)       No
Inconsistent Agreements. The Company has not entered into and the Company will not after the date of this Agreement enter
into any agreement which is inconsistent with the rights granted to the Holders of Registrable Securities pursuant to this Agreement
or otherwise conflicts with the provisions of this Agreement. The rights granted to the Holders hereunder do not and will not
for the term of this Agreement in any way conflict with the rights granted to the holders of the Company’s other issued
and outstanding securities under any such agreements.

 

(d)       Expenses.
All Registration Expenses or Sale Expenses of any Holder shall be borne by the Company, whether or not any Registration Statement
related thereto becomes effective or other sale takes place.

 

(e)       Amendments
and Waivers. The provisions of this Agreement may be amended or waived at any time only by the written agreement of the Company
and the Holders of a Majority of the Registrable Securities. Any waiver, permit, consent or approval of any kind or character
on the part of any such Holders of any provision or condition of this Agreement must be made in writing and shall be effective
only to the extent specifically set forth in writing. Any amendment or waiver effected in accordance with this paragraph shall
be binding upon each Holder of Registrable Securities and the Company.

 

(f)       Notices.
All notices and other communications provided for or permitted hereunder shall be made in writing by hand delivery, registered
first-class mail, facsimile or any courier guaranteeing overnight delivery: (a) if to a Holder, at the most current address given
by such Holder to the Company by means of a notice given in accordance with the provisions of this Section 8(f); and (b) if
to the Company, to NextDecade Corporation, Attention: Krysta De Lima (facsimile: (832) 403-2198; email: Krysta@next-decade.com).
All such notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered;
two (2) Business Days after being deposited in the mail, postage prepaid, if mailed; when receipt is acknowledged, if sent by
facsimile (provided confirmation of transmission is mechanically or electronically generated and kept on file by the sending
party) and on the next Business Day if timely delivered to an air courier guaranteeing overnight delivery.

 

(g)       Successor
and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and assigns of the Company. In
addition, the Demand Holders may assign their rights hereunder to subsequent Holders. If any transferee of any Holder shall acquire
Registrable Securities, in any manner, whether by operation of law or otherwise, such Registrable Securities shall be held subject
to all of the terms of this Agreement, and by taking and holding such Registrable Securities such Person shall be conclusively
deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement, including the restrictions
on resale set forth in this Agreement, and such Person shall be entitled to receive the benefits hereof.

 

(h)       Specific
Enforcement. Without limiting the remedies available to the Holders, the Company acknowledges that any failure by the Company
to comply with its obligations under Section 2 hereof may result in material irreparable injury to the Holders for which
there is no adequate remedy at law, that it would not be possible to measure damages for such injuries precisely and that, in
the event of any such failure, a Holder may obtain such relief as may be required to specifically enforce the Company’s
obligations under Section 2 hereof.

 

(i)       Counterparts.
This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

 

(j)       Headings.
The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

 

(k)       GOVERNING
LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAW OF THE STATE OF DELAWARE REGARDLESS
OF THE LAW THAT MIGHT OTHERWISE GOVERN UNDER APPLICABLE PRINCIPLES OF CONFLICTS OF LAW THEREOF.

 

    	 	20	 

     

    

 

(l)       Severability.
In the event that any one or more of the provisions contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of any such provision in every other respect and
of the remaining provisions contained herein shall not be affected or impaired thereby.

 

(m)       Jurisdiction
and Venue; WAIVER OF JURY TRIAL. The undersigned irrevocably consents to the exclusive jurisdiction and venue of the courts
of the State of Delaware or the federal courts located in the State of Delaware in connection with any matter based upon or arising
out of this Agreement, agrees that process may be served upon it in any manner authorized by the laws of the State of Delaware
and waives and covenants not to assert or plead any objection which it might otherwise have to such manner of service of process.
The undersigned waives, and shall not assert as a defense in any legal dispute, that (a) it is not personally subject to the jurisdiction
of the above named courts for any reason, (b) such Legal Proceeding may not be brought or is not maintainable in such court, (c)
its property is exempt or immune from execution, (d) such Legal Proceeding is brought in an inconvenient forum or (e) the venue
of such Legal Proceeding is improper. THE UNDERSIGNED UNCONDITIONALLY WAIVES ANY RIGHT TO TRIAL BY JURY ON ANY CLAIMS OR COUNTERCLAIMS
ASSERTED IN ANY LEGAL DISPUTE RELATING TO THIS AGREEMENT. IF THE SUBJECT MATTER OF ANY SUCH LEGAL DISPUTE IS ONE IN WHICH THE
WAIVER OF JURY TRIAL IS PROHIBITED, THE UNDERSIGNED SHALL NOT ASSERT IN SUCH LEGAL DISPUTE A NONCOMPULSORY COUNTERCLAIM ARISING
OUT OF OR RELATING TO THIS AGREEMENT. FURTHERMORE, THE UNDERSIGNED SHALL NOT SEEK TO CONSOLIDATE ANY SUCH LEGAL DISPUTE WITH A
SEPARATE ACTION OR OTHER LEGAL PROCEEDING IN WHICH A JURY TRIAL CANNOT BE WAIVED

Ladies and Gentlemen:

 

Reference is made to that certain Agreement
and Plan of Merger (the “Merger Agreement”), dated April 17, 2017, by and among Harmony Merger Corp., a Delaware
corporation (“Parent”), Harmony Merger Sub, LLC, a Delaware limited liability company and wholly-owned subsidiary
of the Parent (“Merger Sub”), NextDecade, LLC, a Delaware limited liability company (“NextDecade”)
and the other signatories parties thereto. Capitalized terms used herein and not otherwise defined shall have the meanings ascribed
to them in the Merger Agreement.

 

To induce the parties to consummate the
Transactions, the undersigned hereby agrees that it will not, during the period commencing on the date hereof and ending [one hundred
and eighty (180)  days after the date hereof] [on the first anniversary of the date hereof] (the “Restricted Period),
[except...] (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract
to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any
shares of Parent Common Stock beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as
amended (the “Exchange Act”)) by the undersigned or any other Related Securities (as defined below) so owned
or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences
of ownership of the shares of Parent Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled
by delivery of shares of Parent Common Stock or such other securities, in cash or otherwise[; provided, that, with respect
to any Related Securities that are delivered to the undersigned or otherwise become unrestricted after the Closing Date and within
the Restricted Period, with respect to such Restricted Securities only, the Restricted Period shall continue until the later of
(A) the first anniversary of the date hereof and (B) one hundred and eighty days (180) days from the date that such Related Securities
were delivered to the undersigned or became unrestricted]. The foregoing sentence shall not apply to (a) transactions relating
to shares of Parent Common Stock or Related Securities acquired in open market transactions after the Merger, (b) if the undersigned
is a corporation, partnership, limited liability company or other business entity, a disposition, transfer or distribution of shares
of Parent Common Stock or Related Securities to its affiliates, limited or general partners, members, stockholders or other equity
holders of the undersigned, (c) if the undersigned is an individual, transfers of shares of Parent Common Stock or Related
Securities as bona fide gifts or to a trust the beneficiaries of which are exclusively the undersigned or immediate family members
of the undersigned, (d) transactions relating to shares of Parent Common Stock or Related Securities by operation of law pursuant
to a qualified domestic order or in connection with a divorce settlement, (e) if the undersigned is an individual, transfers
of shares of Parent Common Stock or Related Securities by will or intestacy, (f) the exercise of options, stock appreciation
rights or warrants to purchase shares of Parent Common Stock or (g) transfers, sales, tenders or other dispositions of Parent
Common Stock to a bona fide third party pursuant to a tender offer for securities of Parent or any merger, consolidation or other
business combination involving a Change of Control of Parent that, in each case with respect to this clause (g), has been approved
by the board of directors of Parent (including, without limitation, entering into any lock-up, voting or similar agreement pursuant
to which the undersigned may agree to transfer, sell, tender or otherwise dispose of Parent Common Stock in connection with any
such transaction, or vote any Parent Common Stock in favor of any such transaction); provided that all shares of Parent
Common Stock subject to this agreement that are not so transferred, sold, tendered or otherwise disposed of remain subject to this
agreement; and provided, further, that it shall be a condition of transfer, sale, tender or other disposition that
if such tender offer or other transaction is not completed, any Parent Common Stock subject to this agreement shall remain subject
to the restrictions herein or (h) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act
for the transfer, sale or any other disposition of shares of Parent Common Stock; provided that (A) in the case
of any transfer, distribution or sale pursuant to clauses (b), (c), (d) or (e) above, each donee, transferee or pledgee shall sign
and deliver a lock-up agreement substantially in the form of this letter, (B) in the case of any transfer or distribution
