encumbrance, right of first refusal, preemptive right or other restriction. 
 (b)    The issuance of the Exchange
Shares to each of the Contributing Investors hereunder is intended to be exempt from registration under the Securities Act pursuant to Rule 506 of Regulation D and/or Section 4(a)(2) of the Securities Act. 

(c)    The Exchange Shares will continue to be Exchange Shares for purposes of this Agreement in the hands of any holder
other than a Contributing Investor (except for OSH Inc. or its subsidiaries and except for transferees in a public offering), and except as otherwise provided herein, each such other holder of the Exchange Shares will succeed to all rights and
obligations attributable to such Contributing Investor as a holder of the Exchange Shares pursuant to this Agreement. The Exchange Shares will also include units of OSH Inc.’s equity interests issued with respect to the Exchange Shares by way
of a split, dividend, distribution or other recapitalization. 
 2.    Representations and Warranties of OSH Inc.
In connection with the transactions contemplated hereby, OSH Inc. represents and warrants to each Contributing Investor that: 

(a)    The execution, delivery and performance of this Agreement has been duly authorized by OSH Inc. and this Agreement
constitutes a valid and binding obligation of OSH Inc., enforceable in 

 
accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, receivership and similar laws affecting the enforcement of
creditors’ rights generally and general equitable principles. The execution, delivery and performance of this Agreement, the consummation of the transactions contemplated hereby and the receipt of the Contributed Interests by OSH Inc. do not
and will not (i) conflict with or result in a breach of the terms, conditions or provisions of, (ii) constitute a default under, (iii) result in the creation of any lien, security interest, charge or lien upon such Contributed
Interests pursuant to, (iv) give any third party the right to modify, terminate or accelerate any obligation under, (v) result in a violation of or (vi) require any authorization, consent, approval, exemption or other action by or
notice to any governmental authority pursuant to, any law to which OSH Inc. is subject, or any agreement, instrument, order, judgment or decree to which OSH Inc. is a party or by which OSH Inc. is bound. 

(b)    The Exchange Shares have been duly authorized and are validly issued, fully paid and
non-assessable. 
 3.    Representations and Warranties of each Contributing
Investor. 
 (a)    In connection with the transactions contemplated hereby, each Contributing Investor represents
and warrants to OSH Inc. that: 
 (i)     The execution, delivery and performance of this Agreement has
been duly authorized by such Contributing Investor and this Agreement constitutes a valid and binding obligation of such Contributing Investor, enforceable in accordance with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium, receivership and similar laws affecting the enforcement of creditors’ rights generally and general equitable principles. The execution, delivery, and performance of this Agreement, the
consummation of the transactions contemplated hereby, and the delivery of the Contributed Interests to OSH Inc. by such Contributing Investor do not and will not (i) conflict with or result in a breach of the terms, conditions or provisions of,
(ii) constitute a default under, (iii) result in the creation of any lien, security interest, charge or lien upon such Contributed Interests pursuant to, (iv) give any third party the right to modify, terminate or accelerate any
obligation under, (v) result in a violation of or (vi) require any authorization, consent, approval, exemption or other action by or notice to any governmental authority pursuant to, any law to which such Contributing Investor is subject,
or any agreement, instrument, order, judgment or decree to which such Contributing Investor is a party or by which such Contributing Investor is bound. 

(ii)    The Exchange Shares to be acquired by such Contributing Investor pursuant to this Agreement will be
acquired for such Contributing Investor’s own account and not with a view to, or intention of, distribution thereof in violation of the Securities Act, or any applicable state securities laws, and the Exchange Shares will not be disposed of in
contravention of the Securities Act or any applicable state securities laws. 
 (iii)    Such
Contributing Investor is an “accredited investor” within the meaning of Rule 501 of Regulation D of the Securities and Exchange Commission, is sophisticated in financial matters and is able to evaluate the risks and benefits of the
investment in the Exchange Shares. 
 (iv)    Such Contributing Investor is able to bear the economic
risk of such Contributing Investor’s investment in the Exchange Shares for an indefinite period of time because the Exchange Shares have not been registered under the Securities Act and, therefore, cannot be sold unless subsequently registered
under the Securities Act or an exemption from such registration is available. 

  
 2 

 (b)    In connection with the transactions contemplated hereby, each GA
Interholdco represents and warrants to OSH Inc. that prior to the contribution of Contributed Interests as contemplated in Section 1 hereof, GA Interholdco has capitalized GA Blocker in order to remove a portion of the
outstanding shareholder debt. Any outstanding shareholder debt held by the GA Blocker which shall not be capitalized pursuant to this Section 3(b) is set forth in Schedule II hereto, and each such debt instrument has a term to maturity of less
than five years. 
 4.    Treatment of Uncapitalized GA Blocker Debt Instruments. OSH Inc. shall (i) treat
each debt instrument identified on Schedule II hereto as indebtedness of GA Blocker for federal and applicable state and local income tax purposes and (ii) file all applicable Tax Returns consistent with such treatment unless otherwise required
by a change in applicable Law. 
 5.    Transferability. Each of the Contributing Investors acknowledges that the
Exchange Shares are subject to certain transfer restrictions. 
 6.    Fractional Units. Notwithstanding anything
to the contrary in this Agreement, no fractional Exchange Shares shall be issued upon the exchange or conversion of any Contributed Interests and in lieu of the issuance of any such fractional Exchange Shares, the aggregate number of Exchange Shares
to be issued to the holder of such Contributed Interests shall be rounded up to the first whole Exchange Share. The parties hereto acknowledge that such rounding in lieu of issuing fractional Exchange Shares is not separately bargained-for consideration, but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience that would otherwise be caused by the issuance of fractional Exchange Shares. 

7.    Notices. Any notice, request, demand, claim or other communication required or permitted to be delivered,
given or otherwise provided under this Agreement must be in writing and must be delivered personally, delivered by nationally recognized overnight courier service or sent by email. Any such notice, request, demand, claim or other communication shall
be deemed to have been delivered and given (a) when delivered, if delivered personally, (b) the business day after it is deposited with such nationally recognized overnight courier service, if sent for overnight delivery by a nationally
recognized overnight courier service or (c) the day of sending, if sent by email prior to 5:00 p.m. (Eastern time) on any Business Day or the next succeeding Business Day if sent by email after 5:00 p.m. (Eastern time) on any Business Day or on

law or in equity) may be brought after the date hereof against any of the parties hereto; provided, however, that OSH Inc.’s obligation to deliver the Exchange Shares pursuant to Section 1(a) and any claims in connection with such

 4 

 (b)    Further Assurances. The parties acknowledge that the
purpose of this Agreement and the transactions contemplated hereby is to effectuate the transactions contemplated herein. To that end, each party shall, in its sole expense, execute and deliver such further agreements, certificates, forms,
elections, filings and instruments of conveyance and transfer and take such additional action as any other party may reasonably request to effect, consummate, confirm or evidence the transactions contemplated herein. 

9.    General Provisions. 

(a)    Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to
be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this Agreement. 
 (b)    Entire
Agreement. This Agreement and the agreements, certificates and other instruments referred to or attached herein and therein, including the Master Structuring Agreement, contain the complete agreement between the parties and supersede any prior
understandings, agreements or representations by or between the parties, written or oral, which may have related to the subject matter hereof in any way. 

(c)    Counterparts; Electronic Delivery. This Agreement and any signed agreement or instrument entered into in
connection with this Agreement, and any amendments hereto or thereto, may be executed in one or more counterparts, all of which shall constitute one and the same instrument. Any such counterpart, to the extent delivered by means of a facsimile
machine or by .pdf, .tif, .gif, .peg or similar attachment to electronic mail (any such delivery, an “Electronic Delivery”) shall be treated in all manner and respects as an original executed counterpart and shall be considered to
have the same binding legal effect as if it were the original signed version thereof delivered in person. At the request of any party, each other party or thereto shall re-execute the original form of this Agreement (i.e. the form fully executed by
all of the parties) and deliver such form to all other parties. No party shall raise the use of Electronic Delivery to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of
Electronic Delivery as a defense to the formation of a contract, and each such party forever waives any such defense, except to the extent such defense relates to lack of authenticity. 

(d)    Successors and Assigns; Third Party Beneficiaries. This Agreement shall be binding upon and inure solely to
the benefit of each of the parties and their respective successors and assigns, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature
under or by reason of this Agreement. Except as set forth in the preceding sentence, this Agreement is not intended for the benefit of any Person other than the parties hereto, and no such other Person shall be deemed to be a third party beneficiary
hereof, provided however that Newlight Harbour Point SPV LLC shall be a third-party beneficiary for the purposes of enforcing the consent right set forth in Section 9(h) of this Agreement. 

(e)    Governing Law; Waiver of Jury Trial. All issues and questions concerning the construction, validity,
interpretation and enforceability of this Agreement and the Schedules and the Exhibits hereto shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice of law or conflict of law
rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware. THE PARTIES HEREBY WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN STATUTE, CONTRACT, TORT OR OTHERWISE. THE

ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT BROUGHT BY ANY OTHER PARTY OR ITS SUCCESSORS OR ASSIGNS SHALL BE BROUGHT AND DETERMINED ONLY IN THE DELAWARE CHANCERY COURT AND ANY STATE COURT SITTING IN THE STATE OF DELAWARE TO
WHICH AN APPEAL FROM THE DELAWARE CHANCERY COURT MAY BE VALIDLY TAKEN, AND EACH OF THE PARTIES HEREBY IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE AFORESAID COURTS FOR ITSELF AND WITH RESPECT TO ITS PROPERTY, GENERALLY AND
UNCONDITIONALLY, WITH REGARD TO ANY SUCH ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY. EACH OF THE PARTIES AGREES NOT TO COMMENCE ANY ACTION, SUIT OR PROCEEDING RELATING THERETO EXCEPT IN
THE COURTS DESCRIBED ABOVE IN DELAWARE, OTHER THAN ACTIONS IN ANY COURT OF COMPETENT JURISDICTION TO ENFORCE ANY JUDGMENT, DECREE OR AWARD RENDERED BY ANY SUCH COURT IN DELAWARE AS DESCRIBED HEREIN, AND NO PARTY WILL FILE A MOTION TO DISMISS ANY
ACTION FILED IN A STATE OR FEDERAL COURT IN THE STATE OF DELAWARE, ON ANY JURISDICTIONAL OR VENUE-RELATED GROUNDS, INCLUDING THE DOCTRINE OF FORUM NON CONVENIENS. PROCESS IN ANY ACTION OR PROCEEDING REFERRED TO IN THIS SECTION 9(F) MAY
BE SERVED ON ANY PARTY ANYWHERE IN THE WORLD. 
 (g)    Remedies. Each of the parties to this Agreement will be
entitled to enforce its rights under this Agreement specifically, to recover damages and costs (including attorney’s fees) caused by any breach of any provision of this Agreement and to exercise all other rights existing in its favor. The
parties hereto agree and acknowledge that money damages may not be an adequate remedy for any breach of the provisions of this Agreement and that any party may in its sole discretion apply to any court of law or equity of competent jurisdiction
(without posting any bond or deposit) for specific performance and/or other injunctive relief in order to enforce or prevent any violations of the provisions of this Agreement.

 (j)    Adjustments. In the event that the Contributing Investors
determine following the date hereof that any amounts set forth on Schedule I (including the number of Exchange Shares issued to each Contributing Investor) should be adjusted, amended or revised in order to account for or reflect the finally
determined and agreed upon allocation or number of Exchange Shares, then this Agreement and Schedule I may be so amended, modified or revised by either the Contributing Investors without the consent or approval of OSH Inc. in order to reflect
such final allocations or number, it being the intent of the parties hereto that any such amendments, modifications or revisions shall be effective as of the date hereof.

(a)    GA Blocker hereby represents and warrants as follows: 

(i)    GA Blocker is, and has been for its entire existence, classified as a corporation for all relevant
income tax purposes and has no election pending with any Taxing Authority to change its income tax classification.

taking into account all reasonable extensions) and has timely paid all Taxes shown as due on such Tax Returns. All such Tax Returns were filed in accordance with applicable Laws and are true, correct, and complete in all material respect as to all
matters relating to the Taxes shown as payable. 
 (iii)    All Income Tax Returns filed by the GA
Blocker (including any information provided on an IRS Schedule K-1 or similar form provided under applicable state and local Laws) were filed consistent with all tax information provided to the GA Blocker by
OSH LLC (including any information provided on an IRS Schedule K-1 or similar form provided under applicable state and local Laws). GA Blocker did not realize any material item of income prior to the
Contribution Date other than its allocable share of OSH LLC’s income.

 (iv)    GA Blocker is not liable for Taxes of any other
Person (other than OSH LLC) as a transferee or successor or as a result of being a member of a combined, consolidated, unitary, or other affiliated group or any other provision of Law. GA Blocker is not party to any tax sharing or other contract
that could obligate it to pay, indemnify or gross-up any other Person for Taxes incurred by such Person. 

(v)    GA Blocker has not received any notices from any Taxing Authority proposing to conduct an audit,
examination or other proceedings relating to its Tax Returns or Taxes and no such audit, examination, or other proceeding is currently in progress or pending.

result in the GA Blocker incurring any Taxes in periods (or portions thereof) beginning after the Contribution Date relating to income realized in a period ending prior to the Contribution Date. 

(vii)    GA Blocker has paid sufficient estimated Taxes prior to the Closing, to the extent required, such
that it will not have any liability for any unpaid Taxes shown on Tax Returns filed after the Closing Date for a Pre-Closing Tax Period (assuming such Tax Returns are filed in accordance with the most recent
practices and procedures of the GA Blocker) or any liability for Taxes for the pre-Closing portion of any Straddle Period on a Tax Return filed for a Straddle Period after the Closing Date, except to the
extent, if any, that the amount of distributions made by OSH LLC to GA Blocker for any Pre-Closing Tax Period or the pre-Closing portion of any Straddle Period were
insufficient to pay such estimated Taxes. 
 (b)    GA Interholdco hereby represents and warrants that: 

(i)    Each debt instrument issued by GA Blocker (the “GA Blocker Debt”) is held solely by GA
Interholdco. 
 (ii)    No GA Blocker Debt is treated as issued for stock or securities which trade on an
“established securities market” within the meaning of Code Section 1273(b)(3) and the applicable Treasury Regulations. 

(iii)    GA Interholdco’s adjusted tax basis in each GA Blocker Debt instrument for U.S. federal
income tax purposes, and the fair market value of each GA Blocker Debt instrument, is equal to (x) the principal of such GA Blocker Debt instrument plus (y) any accrued but unpaid interest with respect to such GA Blocker Debt instrument.

 (c)    Newlight Blocker hereby represents and warrants as follows: 

(i)    Newlight Blocker is, and has been for its entire existence, classified as a corporation for all
relevant income tax purposes and has no election pending with any Taxing Authority to change its income tax classification.
