limited liability company (the “Sponsor”), Spring Valley Acquisition Corp., a Cayman Islands exempted company (“Acquiror”),
and Dream Holdings, Inc., a Delaware corporation (the “Company”). The Sponsor, Acquiror and the Company are sometimes
referred to herein individually as a “Party” and collectively as the “Parties”. Capitalized terms
used but not otherwise defined herein shall have the meanings ascribed to such terms in the Merger Agreement (as defined below).


 


WHEREAS, Sponsor holds 5,630,000
Class B ordinary shares of Acquiror (“Class B Shares”), of which 750,000 are held indirectly by those Persons
listed on Schedule I attached hereto (such Persons, the “Strategic Investors”);


 


WHEREAS,
Acquiror, Spring Valley Merger Sub, Inc., a Delaware corporation, and the Company entered into that certain Merger Agreement,
dated as of the date hereof (as it may be amended, restated or otherwise modified from time to time in accordance with its terms, the
 “Merger Agreement”);


 


WHEREAS, pursuant to their
terms, all of the Class B Shares shall be converted into Acquiror Common Stock at the time of consummation of the Merger (the “Conversion”);
and


 


WHEREAS, the Merger Agreement
contemplates that the Parties will enter into this Agreement contemporaneously with the execution and delivery of the Merger Agreement
by the parties thereto.


 


NOW, THEREFORE, in consideration
of the premises and the mutual promises contained herein and for other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the Parties, each intending to be legally bound, hereby agree as follows:


 


1.            Vesting
and Forfeiture.


 


(a)            The
Sponsor agrees that, as of immediately following the Closing and the Conversion, 1,500,000 shares of the Acquiror Common Stock beneficially
owned by the Sponsor immediately following the Closing and the Conversion (the “Unvested Shares”) shall be subject
to the vesting and forfeiture provisions set forth in this Section 1. For the avoidance of doubt, any Acquiror Common Stock
beneficially owned by any individual other than the Sponsor and any Acquiror Common Stock beneficially owned by the Sponsor (including
all such Acquiror Common Stock held indirectly by the Strategic Investors), other than the Unvested Shares, shall not be subject to vesting
or forfeiture. The Sponsor agrees that it shall not, and shall cause its Affiliates not to, Transfer (other than to an Affiliate) any
Unvested Share held by the Sponsor prior to the date such Unvested Share becomes vested pursuant to Section 1(b).


 


(b)            Vesting
of Acquiror Common Stock.


 


(i)            250,000
of the Unvested Shares shall vest if (A) the price of the Acquiror Common Stock as of the Closing Date equals or exceeds $12.00 per
share, at the close of market on the Closing Date or (B) over each of any 20 Trading Days within any 30 Trading Day period during
the 60 months following the Closing (the “Initial Vesting Measurement Period”) the VWAP of the Acquiror Common Stock
is greater than or equal to $12.00 per share, at the close of market on such 20th Trading Day;


 


(ii)            250,000
of the Unvested Shares shall vest if (A) the price of the Acquiror Common Stock as of the Closing Date equals or exceeds $14.00
per share, at the close of market on the Closing Date or (B) over any Initial Vesting Measurement Period the VWAP of the Acquiror
Common Stock is greater than or equal to $14.00 per share, at the close of market on such 20th Trading Day;


 






    


     


    

 


(iii)          500,000
of the Unvested Shares shall vest if, over each of any 20 Trading Days within any 30 Trading Day period during the 66 months following
the Closing (the “Additional Vesting Measurement Period”), the VWAP of the Acquiror Common Stock is greater than or
equal to $15.00 per share, at the close of market on such 20th Trading Day; and


 


(iv)          500,000
of the Unvested Shares shall vest if (A) the price of the Acquiror Common Stock as of the date that is six months following the Closing
Date equals or exceeds $20.00 per share, at the close of market on such date or (B) over any Additional Vesting Measurement Period

(v)            The
per share stock prices referenced in Section 1(b)(i) through Section 1(b)(iv) above will be equitably
adjusted on account of any changes in the equity securities of Acquiror by way of stock split, stock dividend, combination or reclassification,
or through merger, consolidation, reorganization, recapitalization or business combination, or by any other means.


 


2.            Tax
Treatment. The Parties intend that the Conversion will be treated as a tax-free recapitalization under Section 368(a)(1)(E) of
the Internal Revenue Code of 1986, as amended (the “Code”), and the Sponsor intends to make a protective election under
Section 83(b) of the Code with respect to the receipt of the portion of the Unvested Shares subject to vesting under Section 1(b) of
this Agreement.


 


3.            Forfeiture
of Unvested Acquiror Common Stock. Any Unvested Share that remains unvested (a) pursuant to Section 1(b)(i) through
1(b)(ii) as of the expiration of the Initial Vesting Measurement Period or (b) pursuant to Section 1(b)(iii) through
1(b)(iv) as of the expiration of the Additional Vesting Measurement Period, as applicable, shall be forfeited and shall be
transferred by the Sponsor to Acquiror for cancellation, without any consideration for such transfer.


 


4.            Lock-Up.


 


(a)            Subject
to Section 4(b), the Sponsor hereby agrees that it shall not, and shall cause any of its Permitted Transferees not to, Transfer
any Lock-up Shares until the end of the Lock-up Period.


 


(b)            Notwithstanding
the provisions set forth in Section 4(a), the Sponsor or its Permitted Transferees may Transfer the Lock-up Shares during
the Lock-up Period (i) to (A) Acquiror’s or Sponsor’s officers or directors or (B) any Affiliates of the Sponsor;

the case of an individual, by virtue of laws of descent and distribution upon death of such individual; or (iv) by virtue of the
laws of the State of Delaware or the Sponsor limited liability company agreement upon dissolution of the Sponsor.

after the Closing Date and (B) over any 20 Trading Days within any 30 Trading Day period the VWAP of the Acquiror Common Stock is

anything to the contrary in this Agreement, any waiver, termination, shortening or other amendment or modification to any lock-up agreement
applicable to the Acquiror Common Stock held by any Company Stockholder which improves the terms of any such lock-up for such Company
Stockholder shall apply pro rata and on the same terms to the Lock-Up of the Sponsor hereunder and the provisions of this Section 4
shall be deemed immediately and automatically waived, terminated, shortened or amended or modified, as the case may be, without further
action of the Parties.


 


(e)           From

in each Stockholder receiving a number of Acquiror Common Stock equal to the amount of Acquiror Common Stock that such Company Stockholder
would have received pursuant to the Merger Agreement in effect as of the time immediately prior to the effectiveness of such amendment.
