ARTICLE II. 
 CALL RIGHT

 Section 2.1 The Call Right Assets. 

(a) The Call Right Assets. SunEdison shall from time to time set forth on Exhibit A a list of Call Right Assets that are the
subject of the Call Right, described below. SunEdison may add projects to the list on Exhibit A at its sole discretion, but only if such projects are (i) located in an Approved Country and (ii) the subject of a fully executed Power
Purchase Agreement (or are expected to have a fully executed Power Purchase Agreement prior to the commencement of the Commercial Operations Date for such project) with a counterparty that, in Terra’s reasonable discretion, is credit-worthy,
and such projects shall then be deemed Call Right Assets. SunEdison agrees to propose to Terra a list of projects to add to the Call Right Assets on Exhibit A and commercial terms related thereto in reasonable detail on a quarterly basis on
or within 30 calendar days before September 30 and December 31 of 2014 and March 31, June 30, September 30 and December 31 of each of 2015 and 2016 or until such other time as mutually agreed by the Parties.
For so long as there is a Roll Over under Section 2.2(b), SunEdison shall continue to propose to Terra a list of projects to add to the Call Right Assets on Exhibit A and commercial terms related thereto in reasonable detail on a
quarterly basis on or within 30 calendar days before March 31, June 30, September 30 and December 31 of each year. 

(b) Terminated Call Right Asset. Notwithstanding anything to the contrary in this Agreement, prior to the time the Parties enter into a
definitive agreement governing the terms and conditions of the purchase and sale of a Call Right Asset (a “Project Agreement”), SunEdison may remove any Call Right Asset from Exhibit A effective upon notice to Terra in the
event that, in SunEdison’s reasonable discretion, a project is unlikely to be successfully 

  
 5 








 
completed (a “Terminated Call Right Asset”). SunEdison shall be prohibited from offering a Terminated Call Right Asset to any Third Party prior to satisfaction of the CAFD
Commitment and shall be required to replace any Terminated Call Right Asset within 45 days following the date that it provides notice to Terra of such Terminated Call Right Asset by adding one or more reasonably equivalent projects (taking into
account such factors as the project’s expected contribution to CAFD, the location of its operations and credit rating of the counterparty) to Exhibit A and acceptable by Terra in its reasonable discretion. 

Section 2.2 The CAFD Commitment. 

(a) The CAFD Commitment. SunEdison hereby agrees that it shall offer sufficient Call Right Assets under the procedures outlined in this
Agreement that will generate (i) during the period after the IPO Date and prior to the end of calendar year 2015, solar projects that are projected to generate an aggregate of at least $75.0 million of CAFD during the first 12 months following
each project’s respective Commercial Operations Date (the “2015 CAFD Commitment”), and (ii) during calendar year 2016, solar projects that are projected to generate an aggregate of at least $100.0 million of CAFD during
the first 12 months following each project’s respective Commercial Operations Date (the “2016 CAFD Commitment” and together with the 2015 CAFD Commitment, the “CAFD Commitment”). The Parties shall work in good
faith to mutually agree on the amount of CAFD a project pertaining to a Call Right Asset is expected to generate on a forward-looking 12-month basis as of the Commercial Operations Date of each project (the “Estimated CAFD”). If
SunEdison and Terra are unable to agree on the Estimated CAFD within ninety (90) calendar days after a Call Right Asset is added to Exhibit A (or such shorter period as will still allow Terra to timely complete the Call Right exercise
process pursuant to this Agreement), SunEdison and Terra shall, upon written notice from either SunEdison or Terra to the other, engage a Third Party Advisor to determine the Estimated CAFD. The Parties agree that once a Call Right Asset has
been acquired by Terra, the Estimated CAFD (as such estimate may be updated from time to time pursuant to changes in the construction and financing structure of the Call Right Asset or as the Parties may otherwise mutually agree) of such Call Right
Asset will be credited toward SunEdison’s satisfaction of the CAFD Commitment (the aggregate amount of CAFD that the Call Right Assets acquired by Terra are projected to generate during the first 12 months following each project’s
respective Commercial Operations Date shall be referred to as the “Satisfied CAFD Commitment”). For the avoidance of doubt, nothing in this Agreement shall be deemed to prohibit (x) SunEdison from offering Call Right Assets
that exceed the CAFD Commitment or (y) the Parties from agreeing on the Estimated CAFD for one or more Call Right Assets that exceeds the CAFD Commitment in any particular year or in the aggregate. 

(b) The Roll Over. If the Satisfied CAFD Commitment for projects acquired by Terra during the period after the IPO Date and prior to
the end of calendar year 2015 is less than $75.0 million or during calendar year 2016 is less than $100.0 million, then, to the extent of any such shortfall, SunEdison hereby agrees that it shall continue to offer sufficient Call Right Assets
(including, if applicable, in 2017 and subsequent years) until the Satisfied CAFD Commitment satisfies the CAFD Commitment (such period of time referred to as the “Roll Over”). 

  
 6 








 Section 2.3 Option to Purchase the Call Right Assets. 

(a) The Call Right. Subject to Section 2.1(b), SunEdison hereby grants to Terra the right and option, on the terms and
subject to the conditions set forth in this Agreement, to purchase some or all of the Call Right Assets, exercisable by Terra in its sole discretion at any time during the Call Right Period (the “Call Right”). SunEdison will take
all actions reasonably necessary to cause the Call Right to be exercisable in accordance with this Article II, including by taking any actions necessary to facilitate and enforce such exercise and to consummate the transactions contemplated
by this Article II. 
 (b) The Call Right Price. The Parties shall work in good faith to mutually agree on the Fair Market
Value of each Call Right Asset (the “Call Right Price”) within a reasonable time after the date SunEdison adds a Call Right Asset to Exhibit A. If SunEdison and Terra are unable to agree on the Call Right Price within ninety
(90) calendar days after a Call Right Asset is added to Exhibit A, SunEdison and Terra shall, upon written notice from either SunEdison or Terra to the other, engage a Third Party Advisor to determine the Call Right Price. If Terra
exercises a Call Right for a particular Call Right Asset, Terra agrees that it shall pay for such Call Right Asset in cash, unless otherwise mutually agreed by the Parties, an amount equal to the Call Right Price. 

Section 2.4 Exercise of a Call Right. 

(a) At any time during the Call Right Period, Terra may provide written notice to SunEdison of its exercise of the Call Right (a “Call
Right Notice”), which notice shall identify the particular Call Right Asset. Following any valid delivery of a Call Right Notice, SunEdison and Terra shall negotiate in good faith to agree on any other material economic terms not included
in Exhibit A and to enter into a Project Agreement for the Call Right Asset subject of the Call Right Notice. If SunEdison and Terra are unable to agree on such other terms and conditions of a Project Agreement within thirty
(30) calendar days of delivery of a Call Right Notice, SunEdison and Terra shall, upon written notice from either SunEdison or Terra to the other, engage Third Party Advisor to determine the material economic terms on which SunEdison and Terra
are unable to agree so that such material economic terms reflect common practice in the relevant market. 
 (b) Upon receipt of the Third
Party Advisor’s final determination, Terra will have the option, but not the obligation, to purchase the applicable Call Right Asset on the material economic terms determined by the Third Party Advisor or as otherwise mutually agreed by the
Parties, exercisable by delivery of written notice to SunEdison within ten (10) Business Days of such determination (a “Second Call Right Notice”). The “Final Call Right Notice” means a Call Right Notice;
provided that if Terra delivers a Second Call Right Notice, then the term “Final Call Right Notice” means the Second Call Right Notice. 

(c) If Terra delivers a Final Call Right Notice before the end of the Call Right Period, SunEdison shall be obligated to sell the applicable
Call Right Asset to Terra, and Terra shall be obligated to purchase the applicable Call Right Asset from SunEdison on the economic terms set forth in Exhibit A or as otherwise mutually agreed by the Parties or provided by the Third Party
Advisor, on or about the Commercial Operations Date or on any other such date as the Parties may mutually agree. If the closing of such transaction shall not have been consummated within 120 days following Terra’s delivery of a Final Call Right
Notice, either 

  
 7 








 
SunEdison or Terra shall be entitled to terminate any obligation to sell or purchase, as applicable, the Call Right Asset under this Article II and the related Project Agreement, and upon
such termination neither SunEdison nor Terra shall have any obligation to sell or purchase the Call Right Asset pursuant thereto; provided that if a Party’s breach of this Article II or the related Project 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 Call Right Asset under this Article II or the related Project Agreement;
provided further that Terra may extend the period for closing under such Project 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 Terra
is not in breach of such Project Agreement and is continuing to use reasonable efforts to work toward a closing of such Project Agreement. 

(d) If Terra does not deliver a Final Call Right Notice before the end of the Call Right Period, SunEdison may offer to sell the applicable
Call Right Asset to any other Third Party, and Terra shall be deemed to have waived any right to purchase such Call Right Asset. 
 (e)
Subject to Section 2.5, SunEdison shall not make any Transfers with respect to any of the Call Right Assets from the date hereof through the later of (i) the termination of the Call Right Period and (ii) the termination of any
Project Agreement entered into pursuant to Section 2.4(c) prior to the expiration of the Call Right Period. 

Section 2.5 Right of First Refusal. 

If SunEdison receives a bona fide offer from a Third Party to purchase a Call Right Asset before Terra delivers a Final Call Right Notice in
accordance with the terms of Section 2.4 (a “Third Party Offer”), SunEdison shall provide notice to Terra of the terms of such Third Party Offer in reasonable detail, and Terra shall have the right, but not the
obligation, to purchase such Call Right Asset on substantially similar terms (but at a price no less than specified in the Third Party Offer) by notifying SunEdison within ten (10) Business Days of receiving the notice of such Third Party
Offer. If within such ten (10) Business Day period, Terra provides such notice to SunEdison, such notice shall be treated as a Call Right Notice under Section 2.4. If within such ten (10) Business Day period, Terra does not
provide such notice to SunEdison, SunEdison may offer to sell the applicable Call Right Asset to any other Third Party on terms no more favorable than those set forth in the Third Party Offer and offered to Terra, and Terra shall be deemed to have
waived any right to purchase such Call Right Asset, and such Call Right Asset shall not be counted toward the Satisfied CAFD Commitment. 

Section 2.6 Priced Call Right Assets 

Notwithstanding anything in this Agreement, including Section 2.5, prior to satisfaction of the CAFD Commitment SunEdison may not market,
negotiate, accept an offer or sell a Priced Call Right Asset to any Third Party unless and until Terra delivers a notice that it is forfeiting its Call Right with respect to such Priced Call Right Asset. 

Section 2.7 Third Party Advisor 

If the Parties engage a Third Party Advisor under the terms of this Agreement, the Third Party Advisor shall be provided with access to all
information prepared by or on behalf of 

  
 8 








 
SunEdison and Terra with respect to the applicable Call Right Asset reasonably requested by the Third Party Advisor. The Third Party Advisor will determine the Estimated CAFD, Call Right Price or
other material economic terms on which SunEdison and Terra are unable to agree, as applicable depending on the purpose for which the Parties have engaged the Third Party Advisor, within thirty (30) calendar days of its engagement or, to the
extent reasonably feasible, such shorter period as will still allow Terra to timely complete the Call Right exercise process pursuant to this Agreement. Each of SunEdison and Terra will pay fifty percent (50%) of the fees and expenses of
such Third Party Advisor engaged by SunEdison and Terra; provided that if Terra does not agree to purchase the Call Right Asset under the terms of this Agreement, Terra shall be responsible for one hundred percent (100%) of such fees and
expenses. 
 ARTICLE III. 

RIGHT OF FIRST OFFER 

Section 3.1 ROFO Assets 

During the Term, SunEdison hereby grants to Terra and its Affiliates a right of first offer on any proposed Transfer of any project developed
by SunEdison located in an Approved Country other than the projects pertaining to the Call Right Assets (each individually a “ROFO Asset” and collectively, the “ROFO Assets”). For the avoidance of doubt, the
obligations in this Article III shall remain in effect throughout the Term regardless of whether SunEdison has satisfied the CAFD Commitment. 

Section 3.2 Notice of Transaction Related to ROFO Assets and Negotiation of Definitive Terms for Transaction. SunEdison
agrees to deliver a written notice to Terra no later than twenty (20) calendar days prior to engaging in any negotiation regarding any proposed Transfer of any ROFO Asset (or any portion thereof), setting forth in reasonable detail the material
terms and conditions of the proposed transaction (such notice, a “Transaction Notice”). If SunEdison delivers any Transaction Notice to Terra, then SunEdison and Terra shall enter non-binding discussions and negotiate in good faith
to attempt to agree on definitive terms acceptable to both Parties, in their sole and absolute discretion, for the Transfer of the applicable ROFO Asset to Terra or any of its Affiliates. If, within twenty (20) calendar days after the
delivery of such Transaction Notice (the “Negotiation Period”), the Parties have not agreed to definitive terms for the Transfer of such ROFO Asset to Terra, SunEdison will be able, within the next one hundred twenty
(120) calendar days, to Transfer such ROFO Asset to a Third Party (or agree in writing to undertake such transaction with a Third Party) in accordance with the terms of Section 3.3. 

Section 3.3 Negotiations with Third Parties. Neither SunEdison nor any of its representatives, agents or Affiliates
(excluding Terra and its direct or indirect subsidiaries, which subsidiaries shall not include any ROFO Asset prior to the acquisition thereof by Terra or any of its Affiliates in accordance with the terms and conditions of this Agreement) shall
solicit offers from, negotiate with or enter into any agreement with any Third Party for the Transfer of any ROFO Asset (or any portion thereof) until the expiration of the Negotiation Period related to such ROFO Asset and the proposed Transfer (the
“ROFO Termination Date”). Terra agrees and acknowledges that from and after the ROFO Termination Date for any ROFO Asset and the 

  
 9 








 
applicable proposed Transfer: (a) SunEdison shall have the absolute right to solicit offers from, negotiate with or enter into agreements with any Third Party to Transfer such ROFO Asset, on
terms generally no less favorable to SunEdison than those offered to Terra pursuant to the Transaction Notice, and (b) SunEdison shall have no further obligation to negotiate with Terra regarding, or offer Terra the opportunity to acquire any
interest in, such ROFO Asset; provided, that the final terms of the Transfer of any ROFO Asset to any Third Party be on terms generally no less favorable to SunEdison than those offered to Terra pursuant to the Transaction Notice.

tort, for any consequential, incidental, indirect, special or punitive damages of such other Person, including loss of future revenue, or income or profits, or any diminution of value or multiples of earnings damages relating to the breach or
alleged breach hereof, whether or not the possibility of such damages has been disclosed to the other party in advance or could have been reasonably foreseen by such other party. 

ARTICLE V. 

CONFIDENTIALITY 

Section 5.1 SunEdison Confidential Information. Terra shall keep confidential and not make any public announcement or
disclose to any Person any terms of any other documents, materials, data or other information with respect to any ROFO Asset which is not generally known to the public (the “SunEdison Confidential Information”); provided,

obligations of confidentiality that are no less stringent than the obligations set forth herein. Terra shall indemnify and hold harmless the SunEdison Indemnitees for any Losses incurred by any of the SunEdison Indemnitees for a breach or
default of Terra’s obligations under this Section 5.1. This Section 5.1 shall survive the termination of this Agreement for twelve months following the Effective Date.
