MISCELLANEOUS 

Section 4.01 US Income Tax Treatment. The transactions contemplated hereby, taken together with the sale of shares of PEG Inc. to the

agree to adjust the Total Equity Consideration as between themselves, effective at the times of their respective contributions and conveyances, so that PRHC receives consideration equal to that fair market value as so finally determined.

assumption or novation and to perform such other acts as may be reasonably necessary or expedient to further the purposes of this Agreement and the transactions contemplated by this Agreement.

ARTICLE II. 

GULF WIND INTEREST PURCHASE OPTION 
 Section 2.1. Option to Purchase the Gulf Wind Interest. 
 (a) PEG LP hereby
grants to PEG Inc. the unconditional right and option to purchase for fair market value (as determined in accordance with this Agreement) all of the Gulf Wind Interest (the “Gulf Wind Purchase Right”), exercisable by PEG Inc. in its
sole discretion at any time during the Gulf Wind Purchase Right Period, and will take all actions necessary to cause the Gulf Wind Purchase Right to be exercisable in accordance with this Article II, including by causing each PEG LP Entity to
take any actions necessary to facilitate and enforce such exercise 

  
 4 

 
and to consummate the transactions contemplated by this Article II. For the avoidance of doubt, if a Gulf Wind Purchase Right Notice (as defined below) is provided during the Gulf Wind
Purchase Right Period, the Gulf Wind Purchase Right shall survive until the transfer of the Gulf Wind Interest pursuant to this Article II is consummated (or earlier terminated in accordance with this Article II below). 

(b) The transfer of the Gulf Wind Interest in connection with the exercise of the Gulf Wind Purchase Right shall be accomplished pursuant
to the transfer of all of the Class B Units or other Equity Interests in Pattern Gulf Wind Holdings LLC directly or indirectly held by the PEG LP Entities, or in such other manner as PEG Inc. and PEG LP shall reasonably agree, taking into account
tax efficiencies, third party consents and other reasonable considerations. 
 Section 2.2. Procedures. 

(a) At any time during the Gulf Wind Purchase Right Period, PEG Inc. may provide written notice to PEG LP of its exercise of the Gulf
Wind Purchase Right (a “Gulf Wind Purchase Right Notice”), which notice shall include the fair market value it proposes to pay for the Gulf Wind Interest, and the other material economic terms of the purchase. Following
delivery of the Gulf Wind Purchase Right Notice, PEG LP shall have 10 Business Days to reasonably object by written notice to PEG Inc. to the fair market value or any other material economic terms set forth in the Gulf Wind Purchase Right Notice (a
“Gulf Wind FMV Objection Notice”), which Gulf Wind FMV Objection Notice shall include PEG LP’s alternative proposal for any fair market value or other material economic terms. If PEG LP does not so deliver a Gulf Wind FMV
Objection Notice within such 10 Business Day period, PEG LP shall no longer have a right to object to the terms of the Gulf Wind Purchase Right Notice and shall be deemed to have irrevocably agreed to the fair market value and other terms set forth
in the Gulf Wind Purchase Right Notice; and such Gulf Wind Purchase Right Notice shall be deemed to be the Final Gulf Wind Purchase Right Notice (as defined below). Following any valid delivery within the period specified above of a Gulf Wind FMV
Objection Notice, PEG LP and PEG Inc. shall negotiate in good faith to resolve any objections set forth in the Gulf Wind FMV Objection Notice. If PEG Inc. and PEG LP are unable to agree on the fair market value of the Gulf Wind Interest and/or the
other material economic terms objected to in a validly delivered Gulf Wind FMV Objection Notice within 30 calendar days of such delivery, PEG Inc. and PEG LP shall, upon written notice from either PEG Inc. or PEG LP to the other, engage a Third
Party Advisor to determine the fair market value of the Gulf Wind Interest and/or the other material economic terms on which PEG Inc. and PEG LP are unable to agree. In determining the fair market value of the Gulf Wind Interest and/or the
other material economic terms on which the Gulf Wind Interest is to be sold, the Third Party Advisor shall be provided with access to the Gulf Wind Purchase Right Notice, Gulf Wind FMV Objection Notice, including the proposed sale and purchase
values and terms for the offer submitted by PEG Inc. and PEG LP, respectively, and to all information prepared by or on behalf of PEG Inc. and PEG LP with respect to the Gulf Wind Interest and reasonably requested by the Third Party
Advisor. The Third Party Advisor will determine the fair market value of the Gulf Wind Interest and/or the other material economic terms on which PEG Inc. and PEG LP are unable to agree within 30 calendar days of its engagement. Upon
receipt of the Third Party Advisor’s final determination, PEG Inc. will have the option, but not the obligation, to purchase the Gulf Wind Interest for the fair market value and on the other material economic terms determined by the Third Party
Advisor (and, if 

  
 5 

 
applicable, on other terms set forth in the Gulf Wind Purchase Right Notice for which no objection was set forth in a validly delivered Gulf Wind FMV Objection Notice), exercisable by delivery of
written notice to PEG LP within 10 Business Days of such determination (a “Second Gulf Wind Purchase Right Notice”) setting forth such election and the determined fair market value and other material economic terms applicable to the
Gulf Wind Purchase Right. Each of PEG Inc. and PEG LP will pay fifty percent (50%) of the fees and expenses of any Third Party Advisor engaged by PEG Inc. and PEG LP pursuant to this Section 2.2(a). The “Final Gulf Wind
Purchase Right Notice” shall mean: (i) the Gulf Wind Purchase Right Notice if PEG LP does not deliver a Gulf Wind FMV Objection Notice in accordance with this Section 2.2(a) or (ii) the Second Gulf Wind Purchase Right
Notice if PEG LP delivers a Gulf Wind FMV Objection Notice in accordance with this Section 2.2(a). 
 (b) If PEG
Inc. delivers a Final Gulf Wind Purchase Right Notice, PEG LP shall be obligated to sell the Gulf Wind Interest to PEG Inc. and PEG Inc. shall be obligated to purchase the Gulf Wind Interest from PEG LP at the fair market value and on the other
economic terms set forth in the Final Gulf Wind Purchase Right Notice, as well as on the following terms and conditions (which shall be further documented and set forth in a purchase and sale agreement that shall be entered into by the Parties):

 (i) PEG Inc. will deliver to PEG LP the cash purchase price specified in the Final Gulf Wind Purchase Right
Notice and PEG LP will deliver to PEG Inc. the Gulf Wind Interest (together with reasonable evidence and instruments of transfer with respect thereto) within 120 days of PEG Inc.’s delivery of a Final Gulf Wind Purchase Right Notice (unless
such period is otherwise extended pursuant to Section 2.2(b)(iii)); 
 (ii) PEG LP will provide
customary representations and warranties with respect to title to the Gulf Wind Interest being free and clear of liens and any third party rights, valid conveyance, non-contravention, valid existence and due authorization, execution and authority,
and any other such matters as PEG Inc. may reasonably request, with customary indemnification and survival; and 

(iii) if the closing of the acquisition of the Gulf Wind Interest shall not have been consummated within 120 days
following PEG Inc.’s delivery of a Final Gulf Wind Purchase Right Notice, either PEG LP or PEG Inc. shall be entitled to terminate any obligation to sell or purchase, as applicable, the Gulf Wind Interest under this Article II and the
related purchase and sale agreement, and upon such termination neither PEG LP nor PEG Inc. shall have any obligation to sell or purchase the Gulf Wind Interest pursuant thereto; provided that if a Party’s breach of this Article II
or the related purchase and sale agreement has resulted in the failure of the closing to occur by such date, such Party shall not be entitled to so terminate its obligation to sell or purchase, as applicable, the Gulf Wind Interest under this
Article II or the related purchase and sale agreement; provided further that PEG Inc. may extend the period for closing under such purchase and sale agreement for a period not to exceed an additional 120 days (unless the Parties
mutually agree in writing to an extension of more than 120 days) if PEG Inc. is not in breach of such purchase and sale agreement and is continuing to use reasonable efforts to work toward a closing of such purchase and sale agreement. 

  
 6 

 (c) PEG LP shall not, and shall cause the PEG LP Entities not to, make any Transfers with
respect to the Gulf Wind Interest from the date hereof through the later of (i) the termination of the Gulf Wind Purchase Right Period and (ii) the termination of any purchase and sale agreement entered into pursuant to
Section 2.2(b) prior to the expiration of the Gulf Wind Purchase Right Period, it being agreed and understood that Transfers by the PEG LP Entities to PEG Inc. shall otherwise be made in accordance with the other provisions of this
Article II. 
 ARTICLE III. 
 PROJECT PURCHASE RIGHT OF FIRST OFFER 
 Section 3.1. Project Purchase
Right of First Offer. For the term set forth in Section 3.3, PEG LP hereby grants PEG Inc. a right of first offer on any proposed Transfer by any PEG LP Entity of all or any portion of such PEG LP Entity’s ownership interest in
any power generation or transmission facility or project now or hereafter owned in whole or in part by any PEG LP Entity in any stage, including in development, construction or commercial operation (each a “Project”), in accordance
with Section 3.2. PEG LP will take all actions necessary to cause such right of first offer to be exercisable in accordance with this Article III, including by causing each PEG LP Entity to take any actions necessary to facilitate
and enforce such exercise and to consummate the transactions contemplated by this Article III. 
 Section 3.2.
Procedures for Rights of First Offer. 
 (a) In the event that any PEG LP Entity proposes to Transfer all or any portion
of its ownership interest in any Project, PEG LP shall give PEG Inc. written notice within a commercially reasonable amount of time setting forth the details of the proposed Transfer, including a description of the Project (including the
mega-wattage, stage of development or construction, material counterparties, details of the project contracts and other material information with respect to the Project that an acquiror thereof would reasonably be anticipated to request in order to
reasonably diligence and assess such Project), the interest to be Transferred (the “Subject Project Interest”) and any other material terms of the proposed Transfer reasonably known or anticipated by PEG LP (a “Project
Transfer Notice”). 
 (b) Within 30 calendar days (or 60 calendar days in the event that at the relevant time the chief
executive officer of PEG LP is not an employee of PEG Inc.) after delivery of a Project Transfer Notice, PEG Inc. shall either: (i) deliver a written offer to PEG LP to purchase the Subject Project Interest setting forth PEG Inc.’s offer
price (a “Project Offer Price”) and other material terms and conditions on which PEG Inc. proposes to purchase such Subject Project Interest (a “First Rights Project Offer”) or (ii) deliver a written notice to
PEG LP that PEG Inc. will not make a First Rights Project Offer in response to the Project Transfer Notice (a “First Rights Project Declination”). Unless a First Rights Project Offer is rejected pursuant to written notice from PEG
LP delivered to PEG Inc. within 14 calendar days of PEG Inc.’s delivery of a First Rights Project Offer, such First Rights Project Offer shall be deemed to have been accepted by PEG LP, and PEG Inc. shall have the right to acquire the Subject
Project Interest, and PEG LP shall transfer the Subject Project Interest to PEG Inc., on the terms set forth in First Rights Project Offer, and subject to documentation reasonably agreed between the parties. 

  
 7 

 (c) In the event that PEG Inc. delivers a First Rights Project Declination as provided in
Section 3.2(b) above, or PEG LP validly rejects a First Rights Project Offer as provided in Section 3.2(b) above, PEG LP shall not be restricted from Transfering the applicable Subject Project Interest to any Person within
nine months of such delivery or rejection (as applicable); provided, however, that in the event that PEG Inc. has previously delivered a First Rights Project Offer in respect of the Subject Project Interest which offer was rejected,
PEG LP shall only be permitted to Transfer the Subject Project Interest to a party other than PEG Inc. during such nine month period at a price greater than or equal to 105% of the applicable Project Offer Price and on other terms and conditions
that are not materially less favorable to PEG LP than the terms and conditions set forth in any applicable First Rights Project Offer; provided, further, that PEG LP may not provide any material information with respect to the
applicable Subject Project Interest to any actual or potential Transferee of such Subject Project Interest that was not provided to PEG Inc. together with the Project Transfer Notice. If PEG LP does not so consummate the Transfer of the Subject
Project Interest within such nine month period, the terms of this Section 3.2 shall apply anew with respect to any Transfer of such Subject Project Interest. 
 Section 3.3. Term of the Project Purchase Right of First Offer. Section 3.1 and Section 3.2, including the obligations and rights of PEG LP and PEG Inc. thereunder, shall
survive for an initial term of five-years after the Closing Date, and shall automatically renew for successive five-year terms unless PEG LP or PEG Inc. provide written notice of termination to the other not more than 120 calendar days and no less
than 90 calendar days prior to the expiration of the then current term, in which case, Section 3.1 and Section 3.2 (and such obligations and rights) shall terminate and expire at the end of the then current term;
provided, that PEG LP shall have the right to terminate Section 3.1 and Section 3.2 upon written notice delivered to PEG Inc. at any time within 90 calendar days following the third Transfer of an Operational Project

in accordance with Section 3.2 with respect to each such Operational Project or Construction-Ready Project (for the avoidance of doubt, any such project must have been an Operational Project or
Construction-Ready Project when the related First Rights Project Offer was delivered to PEG Inc.); provided, further, that notwithstanding any termination or expiration of Section 3.1
and Section 3.2, if any First Rights Project Offer shall have been delivered prior to such termination or expiration, the obligations and rights of the Parties with respect to the Subject Project Interest subject thereto shall survive
until the applicable terms of Section 3.2 with respect thereto have been complied with and performed in full.

parties.

above, or PEG LP validly rejects a First Rights PEG LP Offer as provided in Section 4.2(b) above, PEG LP and the PEG LP Partners shall be free to Transfer the PEG LP Interests to any Person within nine months of such delivery or
rejection (as applicable); provided, however, that in the event that PEG Inc. had previously delivered a First Rights PEG LP Offer that was rejected, PEG LP and the PEG LP Partners shall only be permitted to Transfer the PEG LP
Interests to a party other than PEG Inc. during such nine month period at a price greater than or equal to 105% of the applicable PEG LP Offer Price and on other terms and conditions that are not materially less favorable to PEG LP and the PEG LP
Partners than the terms and conditions set forth in any applicable First Rights PEG LP Offer; provided, further, that PEG LP and the PEG LP Partners may not provide any material information with respect to PEG LP, its assets or the PEG
LP Interests to any actual or potential Transferee of the PEG LP Interests that was not provided to PEG Inc. together with the PEG LP Transfer Notice. If PEG LP does not so consummate the Transfer of the PEG LP Interests within such nine month
period, the terms of this Section 4.2 shall apply anew with respect to any Transfer of the PEG LP Interests.
