Section 2.                   Demand Registrations.

(a)         Requests for Registration.  Subject to the terms and conditions of this Agreement, the holders of at least a majority of the Registrable Securities may request registration under the Securities Act of all or any portion of their Registrable Securities on Form S-1 or any similar long-form registration (“Long-Form Registrations”), and the holders of at least a majority of the Registrable Securities may request registration under the Securities Act of all or any portion of their Registrable Securities on Form S-3 or any similar short-form registration (“Short-Form Registrations”) if available.  All registrations requested pursuant to this Section 2(a) are referred to herein as “Demand Registrations”. The holders of a majority of the Registrable Securities making a Demand Registration may request that the registration be made pursuant to Rule 415 under the Securities Act (a “Shelf Registration”) and, if the Company is a WKSI at the time any request for a Demand Registration is submitted to the Company, that such Shelf Registration be an automatic shelf registration statement (as defined in Rule 405 under the Securities Act) (an “Automatic Shelf Registration Statement”).  Within ten days after the filing of the registration statement relating to the Demand Registration, the Company shall give written notice of the Demand Registration to all other holders of Registrable Securities and, subject to the terms of Section 2(e), shall include in such Demand Registration (and in all related registrations and qualifications under state blue sky laws and in any related underwriting) all Registrable Securities with respect to which the Company has received written requests for inclusion therein within 15 days after the receipt of the Company’s notice; provided that, with the consent of the holders of at least a majority of the Registrable Securities requesting such registration, the Company may provide notice of the Demand Registration to all other holders of Registrable Securities within three business days following the non-confidential filing of the registration statement with respect to the Demand Registration so long as such registration statement is not an Automatic Shelf Registration Statement.  Each Holder agrees that such Holder shall treat as confidential the receipt of the notice of Demand Registration and shall not disclose or use the information contained in such notice of Demand Registration without the prior written consent of the Company until such time as the information contained therein is or becomes available to the public generally, other than as a result of disclosure by the Holder in breach of the terms of this Agreement.

(b)         Long-Form Registrations.  The holders of Registrable Securities shall be entitled to an unlimited number of Long-Form Registrations in which the Company shall pay all Registration Expenses (as defined in Section 6(a)), whether or not any such registration is consummated.  All Long-Form Registrations shall be underwritten registrations.

(c)          Short-Form Registrations.  In addition to the Long-Form Registrations provided pursuant to Section 2(b), the holders of a majority of the Registrable Securities shall be entitled to an unlimited number of Short-Form Registrations in which the Company shall pay all Registration Expenses.  Demand Registrations shall be Short-Form Registrations whenever the

5

Company is permitted to use any applicable short form and if the managing underwriters (if any) agree to the use of a Short-Form Registration.  After the Company has become subject to the reporting requirements of the Exchange Act, the Company shall use its reasonable best efforts to make Short-Form Registrations available for the sale of Registrable Securities.

(d)         Shelf Registrations.

(i)                                     Subject to the availability of required financial information, as promptly as practicable after the Company receives written notice of a request for a Shelf Registration, the Company shall file with the Securities and Exchange Commission a registration statement under the Securities Act for the Shelf Registration (a “Shelf Registration Statement”).  The Company shall use its best efforts to cause any Shelf Registration Statement to be declared effective under the Securities Act as soon as practicable after filing, and once effective, the Company shall cause such Shelf Registration Statement to remain continuously effective for such time period as is specified in such request, but for no time period longer than the period ending on the earliest of (A) the third anniversary of the date of filing of such Shelf Registration, (B) the date on which all Registrable Securities covered by such Shelf Registration have been sold pursuant to the Shelf Registration, and (C) the date as of which there are no longer any Registrable Securities covered by such Shelf Registration in existence. Without limiting the generality of the foregoing, unless NRG instructs the Company otherwise in writing, prior to expiration of the Holdback Period, the Company shall use its reasonable best efforts to prepare a Shelf Registration Statement with respect to all of the Registrable Securities held by or issuable to NRG in accordance with the terms of the Exchange Agreement (or such other number of Registrable Securities specified in writing by NRG) to enable such Shelf Registration Statement to be filed with the Securities and Exchange Commission as soon as practicable after the expiration of the Holdback Period.

(ii)                                  In the event that a Shelf Registration Statement is effective, the holders of a majority of the Registrable Securities covered by such Shelf Registration Statement shall have the right at any time or from time to time to elect to sell pursuant to an offering (including an underwritten offering (an “Underwritten Takedown”)) Registrable Securities available for sale pursuant to such registration statement (“Shelf Registrable Securities”), so long as the Shelf Registration Statement remains in effect, and the Company shall pay all Registration Expenses in connection therewith. The holders of a majority of the Registrable Securities covered by such Shelf Registration Statement shall make such election by delivering to the Company a written request (a “Shelf Offering Request”) for such offering specifying the number of Shelf Registrable Securities that the holders desire to sell pursuant to such offering (the “Shelf Offering”).  As promptly as practicable, but no later than two business days after receipt of a Shelf Offering Request, the Company shall give written notice (the “Shelf Offering Notice”) of such Shelf Offering Request to all other holders of Shelf Registrable Securities.  The Company, subject to Sections 1(e) and 8 hereof, shall include in such Shelf Offering the Shelf Registrable Securities of any other holder of Shelf Registrable Securities that shall have made a written request to the Company for inclusion in such Shelf Offering (which request shall specify the maximum number of Shelf Registrable Securities intended to be disposed of by such Holder) within seven days after the receipt of the Shelf Offering

6

Notice.  The Company shall, as expeditiously as possible (and in any event within 20 days after the receipt of a Shelf Offering Request, unless a longer period is agreed to by the holders of a majority of the Registrable Securities that made the Shelf Offering Request), use its best efforts to facilitate such Shelf Offering.  Each Holder agrees that such Holder shall treat as confidential the receipt of the Shelf Offering Notice and shall not disclose or use the information contained in such Shelf Offering Notice without the prior written consent of the Company until such time as the information contained therein is or becomes available to the public generally, other than as a result of disclosure by the Holder in breach of the terms of this Agreement.

(iii)                               Notwithstanding the foregoing, if the holders of a majority of the Registrable Securities wish to engage in an underwritten block trade off of a Shelf Registration Statement (either through filing an Automatic Shelf Registration Statement or through a take-down from an already existing Shelf Registration Statement), then notwithstanding the foregoing time periods, such Holders only need to notify the Company of the block trade Shelf Offering two business days prior to the day such offering is to commence (unless a longer period is agreed to by the holders of a majority of the Registrable Securities wishing to engage in the underwritten block trade) and the Company shall promptly notify other holders of Registrable Securities and such other holders of Registrable Securities must elect whether or not to participate by the next business day (i.e. one business day prior to the day such offering is to commence) (unless a longer period is agreed to by the holders of a majority of the Registrable Securities wishing to engage in the underwritten block trade) and the Company shall as expeditiously as possible use its best efforts to facilitate such offering (which may close as early as three business days after the date it commences); provided that the holders of a majority of the Registrable Securities shall use commercially reasonable efforts to work with the Company and the underwriters prior to making such request in order to facilitate preparation of the registration statement, prospectus and other offering documentation related to the underwritten block trade.

(iv)                              The Company shall, at the request of the holders of a majority of the Registrable Securities covered by a Shelf Registration Statement, file any prospectus supplement or, if the applicable Shelf Registration Statement is an Automatic Shelf Registration Statement, any post-effective amendments and otherwise take any action necessary to include therein all disclosure and language deemed necessary or advisable by the holders of a majority of the Registrable Securities to effect such Shelf Offering.

(e)          Priority on Demand Registrations and Shelf Offerings.  The Company shall not include in any Demand Registration or Shelf Offering any securities that are not Registrable Securities without the prior written consent of the holders of at least a majority of the Registrable Securities included in such registration.  If a Demand Registration or a Shelf Offering is an underwritten offering and the managing underwriters advise the Company in writing that in their opinion the number of Registrable Securities and, if permitted hereunder, other securities requested to be included in such offering exceeds the number of Registrable Securities and other securities, if any, which can be sold therein without adversely affecting the marketability, proposed offering price, timing or method of distribution of the offering, the Company shall include in such offering prior to the inclusion of any securities which are not Registrable

7

Securities the number of Registrable Securities requested to be included which, in the opinion of such underwriters, can be sold, without any such adverse effect, pro rata among the respective holders thereof on the basis of the amount of Registrable Securities owned by each such holder.  Alternatively, if the number of Registrable Securities which can be included on a Shelf Registration Statement is otherwise limited by Instruction I.B.6 to Form S-3 (or any successor provision thereto), the Company shall include in such offering prior to the inclusion of any securities which are not Registrable Securities the number of Registrable Securities requested to be included which can be included on such Shelf Registration Statement in accordance with the requirements of Form S-3, pro rata among the respective holders thereof on the basis of the amount of Registrable Securities owned by each such holder.

(f)    Restrictions on Demand Registration and Shelf Offerings

(i)            The Company shall not be obligated to affect any Demand Registration within 90 days after the effective date of a previous Demand Registration or a previous registration in which Registrable Securities were included pursuant to Section 3 and in which there was no reduction in the number of Registrable Securities requested to be included.  The Company may, with the consent of the holders of a majority of the Registrable Securities, postpone, for up to 60 days from the date of the request, the filing or the effectiveness of a registration statement for a Demand Registration or suspend the use of a prospectus that is part of a Shelf Registration Statement for up to 60 days from the date of the Suspension Notice (and defined below) and therefore suspend sales of the Shelf Registrable Securities (such period, the “Suspension Period”) by providing written notice to the holders of Registrable Securities if (A) the Company’s board of directors determines in its reasonable good faith judgment that the offer or sale of Registrable Securities would reasonably be expected to have a material adverse effect on any proposal or plan by the Company or any Subsidiary to engage in any material acquisition of assets or stock (other than in the ordinary course of business) or any material merger, consolidation, tender offer, recapitalization, reorganization or other transaction involving the Company and (B) upon advice of counsel, the sale of Registrable Securities pursuant to the 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 or (y) disclosure would have a material adverse effect on the Company or the Company’s ability to consummate such transaction; provided that in such event, the holders of Registrable Securities shall be entitled to withdraw such request for a Demand Registration or underwritten Shelf Offering and the Company shall pay all Registration Expenses in connection with such Demand Registration or Shelf Offering.  The Company may delay a Demand Registration hereunder only once in any twelve-month period.  The Company may extend the Suspension Period for an additional consecutive 60 days with the consent of the holders of a majority of the Registrable Securities, which consent shall not be unreasonably withheld.

(ii)           In the case of an event that causes the Company to suspend the use of a Shelf Registration Statement as set forth in paragraph (f)(i) above or pursuant to Section 5(a)(vi) (a “Suspension Event”), the Company shall give a notice to the holders of Registrable Securities registered pursuant to such Shelf Registration Statement (a “Suspension Notice”) to suspend sales of the Registrable Securities and such notice shall

8

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.  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).  Each Holder agrees that such Holder shall treat as confidential the receipt of the Suspension Notice and shall not disclose or use the information contained in such Suspension Notice without the prior written consent of the Company until such time as the information contained therein is or becomes available to the public generally, other than as a result of disclosure by the Holder in breach of the terms of this Agreement.  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 Holders’ Counsel, if any, promptly following the conclusion of any Suspension Event and its effect.

(iii)          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 2(f), 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 there are no longer Registrable Securities covered by such Shelf Registration Statement.

(g)   Selection of Underwriters.  The holders of a majority of the Registrable Securities included in any Demand Registration shall have the right to select the investment banker(s) and manager(s) to administer the offering, subject to the Company’s approval which shall not be unreasonably withheld, conditioned or delayed.  If any Shelf Offering is an Underwritten Offering, the holders of a majority of the Registrable Securities participating in such Underwritten Offering shall have the right to select the investment banker(s) and manager(s) to administer the offering relating to such Shelf Offering, subject to the Company’s approval, which shall not be unreasonably withheld, conditioned or delayed.

(h)   Other Registration Rights.  Except as provided in this Agreement, the Company shall not grant to any Persons the right to request the Company or any Subsidiary to register any Capital Stock of the Company or any Subsidiary, or any securities convertible or exchangeable into or exercisable for such securities, without the prior written consent of the holders of a majority of the Registrable Securities.

Section 3.      Piggyback Registrations.

(a)   Right to Piggyback.  Whenever the Company proposes to register any of its securities under the Securities Act (other than (i) pursuant to a Demand Registration, (ii) in connection with registrations on Form S-4 or S-8 promulgated by the Securities and Exchange

9

Commission or any successor or similar forms or (iii) a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of Registrable Securities), and the registration form to be used may be used for the registration of Registrable Securities (a “Piggyback Registration”), the Company shall give prompt written notice (in any event within three business days after its receipt of notice of any exercise of demand registration rights other than under this Agreement and, subject to the terms of Section 3(c) and Section 3(d), shall include in such Piggyback Registration (and in all related registrations or qualifications under blue sky laws and in any related underwriting) all Registrable Securities with respect to which the Company has received written requests for inclusion therein within 20 days after delivery of the Company’s notice.

(b)   Piggyback Expenses.  The Registration Expenses of the holders of Registrable Securities shall be paid by the Company in all Piggyback Registrations, whether or not any such registration became effective.

(c)   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 number which can be sold in such offering without adversely affecting the marketability, proposed offering price, timing or method of distribution of the offering, the Company shall include in such registration (i) first, the securities the Company proposes to sell, (ii) second, the Registrable Securities requested to be included in such registration which, in the opinion of the underwriters, can be sold without any such adverse effect, pro rata among the holders of such Registrable Securities on the basis of the number of shares owned by each such holder, and (iii) third, other securities requested to be included in such registration which, in the opinion of the underwriters, can be sold without any such adverse effect. Registrable Securities beneficially owned by any officer of the Company shall not be eligible to be included in any primary offering of Common Stock without the Company’s consent.

(d)   Priority on Secondary Registrations.  If a Piggyback Registration is an underwritten secondary registration on behalf of holders of the Company’s securities, 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 number which can be sold in such offering without adversely affecting the marketability, proposed offering price, timing or method of distribution of the offering, the Company shall include in such registration (i) first, the securities requested to be included therein by the holders initially requesting such registration and the Registrable Securities requested to be included in such registration which, in the opinion of the underwriters, can be sold without any such adverse effect, pro rata among the holders of such securities on the basis of the number of securities owned by such Holder, and (ii) second, other securities requested to be included in such registration which, in the opinion of the underwriters, can be sold without any such adverse effect.

(e)   Selection of Underwriters.  If any Piggyback Registration is an underwritten offering, the selection of investment banker(s) and manager(s) for the offering must be approved by the holders of a majority of the Registrable Securities included in such Piggyback Registration.  Such approval shall not be unreasonably withheld, conditioned or delayed.

10

(f)    Right to Terminate Registration.  The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 3 whether or not any holder of Registrable Securities has elected to include securities in such registration.  The Registration Expenses of such withdrawn registration shall be borne by the Company in accordance with Section 6.

(i)            in connection with the Company’s initial Public Offering, such Holder shall not (A) offer, sell, contract to sell, pledge or otherwise dispose of (including sales pursuant to Rule 144), directly or indirectly, any Capital Stock of the Company or Yield LLC (including Capital Stock of the Company or Yield LLC that may be deemed to be owned beneficially by such holder in accordance with the rules and regulations of the Securities and Exchange Commission) (collectively, “Securities”), (B) enter into a transaction which would have the same effect as described in clause (A) above, (C) enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences or ownership of any Securities, whether such transaction is to be settled by delivery of such Securities, in cash or otherwise (each of (A), (B) and (C) above, a “Sale Transaction”), or (D) publicly disclose the intention to enter into any Sale Transaction, commencing on the earlier of the date on which the Company gives notice to the holders of Registrable Securities that a preliminary prospectus has been circulated for such initial Public Offering or the “pricing” of such offering and continuing to the date that is 180 days following the date of the final prospectus for such initial Public Offering (the “Holdback Period”), unless the underwriters managing the Public Offering otherwise agree in writing;

(ii)           in connection with all underwritten Public Offerings (including the Company’s initial Public Offering), such Holder shall not effect any Sale Transaction commencing on the earlier of the date on which the Company gives notice to the holders of Registrable Securities of the circulation of a preliminary or final prospectus for such Public Offering or the “pricing” of such offering and continuing to the date that is 90 days following the date of the final prospectus for such Public Offering (a “Follow-On Holdback Period”), unless, if an underwritten Public Offering, the underwriters managing the Public Offering otherwise agree in writing; and

(iii)          in the event that (A) the Company issues an earnings release or discloses other material information or a material event relating to the Company and its Subsidiaries occurs during the last 17 days of the Holdback Period or any Follow-On Holdback Period (as applicable) or (B) prior to the expiration of the Holdback Period or any Follow-On Holdback Period (as applicable), the Company announces that it will

11

release earnings results during the 16-day period beginning upon the expiration of such period, then to the extent necessary for a managing or co-managing underwriter of a registered offering hereunder to comply with FINRA Rule 2711(f)(4), if agreed to by the holders of a majority of the Registrable Securities selling in such Underwritten Offering, the Holdback Period or the Follow-On Holdback Period (as applicable) shall be extended until 18 days after the earnings release or disclosure of other material information or the occurrence of the material event, as the case may be (a “Holdback Extension”).

The Company may impose stop-transfer instructions with respect to the shares of Common Stock and units of Yield LLC (or other securities) subject to the restrictions set forth in this Section 4(a) until the end of such period, including any Holdback Extension.

(a)   Whenever the holders of Registrable Securities have requested that any Registrable Securities be registered pursuant to this Agreement or have initiated a Shelf Offering, (i) such holders shall, if applicable, cause such Registrable Securities to be exchanged into shares of Common Stock in accordance with the terms of the Exchange Agreement prior to sale of such Registrable Securities and (ii) the Company shall use its reasonable best efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof held by a holder of Registrable Securities requesting registration, and pursuant thereto the Company shall as expeditiously as possible:

12

documents proposed to be filed, which documents shall be subject to the review and comment of such counsel);

(iv)          furnish to each seller of Registrable Securities thereunder such number of copies of such registration statement, each amendment and supplement thereto, the prospectus included in such registration statement (including each preliminary prospectus), each Free Writing Prospectus and such other documents as such seller may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller;

(v)           use its reasonable best efforts to register or qualify such Registrable Securities under such other securities or blue sky laws of such jurisdictions as any seller reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the Registrable Securities owned by such seller (provided that the Company shall not be required to (A) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subparagraph or (B) consent to general service of process in any such jurisdiction or (C) subject itself to taxation in any such jurisdiction);

(vi)          notify each seller of such Registrable Securities (A) promptly after it receives notice thereof, of the date and time when such registration statement and each post-effective amendment thereto has become effective or a prospectus or supplement to any prospectus relating to a registration statement has been filed and when any registration or qualification has become effective under a state securities or blue sky law

13

or any exemption thereunder has been obtained, (B) promptly after receipt thereof, of any request by the Securities and Exchange Commission for the amendment or supplementing of such registration statement or prospectus or for additional information, and (C) at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in such registration statement contains an untrue statement of a material fact or omits any fact necessary to make the statements therein not misleading, and, subject to Section 2(f), at the request of any such seller, the Company shall prepare a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements therein not misleading;

(vii)         use reasonable best efforts to cause all such Registrable Securities to be listed on each securities exchange on which similar securities issued by the Company are then listed and, if not so listed, to be listed on a securities exchange and, without limiting the generality of the foregoing, to arrange for at least two market markers to register as such with respect to such Registrable Securities with FINRA;

(viii)        use reasonable best efforts to provide a transfer agent and registrar for all such Registrable Securities not later than the effective date of such registration statement;

(ix)          enter into and perform such customary agreements (including underwriting agreements in customary form) and take all such other actions as the holders of a majority of the Registrable Securities being sold or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities (including, without limitation, effecting a stock split, combination of shares, recapitalization or reorganization);

(x)           make available for inspection by any seller of Registrable Securities, any underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant or other agent retained by any such seller or underwriter, all financial and other records, pertinent corporate and business documents and properties of the Company as shall be necessary to enable them to exercise their due diligence responsibility, and cause the Company’s officers, directors, employees, agents, representatives and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement;

(xi)          take all reasonable actions to ensure that any Free-Writing Prospectus utilized in  connection with any Demand Registration or Piggyback Registration hereunder complies in all material respects with the Securities Act, is filed in accordance with the Securities Act to the extent required thereby, is retained in accordance with the Securities Act to the extent required thereby and, when taken together with the related prospectus, shall not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;

14

(xii)         otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the Securities and Exchange Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve months beginning with the first day of the Company’s first full calendar quarter after the effective date of the registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158;

(xiii)        permit any of Registrable Securities which Holder, in its sole and exclusive judgment, might be deemed to be an underwriter or a controlling person of the Company, to participate in the preparation of such registration or comparable statement and to allow such Holder to provide language for insertion therein, in form and substance satisfactory to the Company, which in the reasonable judgment of such Holder and its counsel should be included;

(xiv)        in the event of the issuance of any stop order suspending the effectiveness of a registration statement, or the issuance of any order suspending or preventing the use of any related prospectus or suspending the qualification of any Common Stock included in such registration statement for sale in any jurisdiction use reasonable best efforts promptly to obtain the withdrawal of such order;

(xv)         use its reasonable best efforts to cause such Registrable Securities covered by such registration statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the sellers thereof to consummate the disposition of such Registrable Securities;

(xvi)        cooperate with the holders of Registrable Securities covered by the registration statement and the managing underwriter or agent, if any, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing securities to be sold under the registration statement and enable such securities to be in such denominations and registered in such names as the managing underwriter, or agent, if any, or such holders may request;

(xvii)       cooperate with each holder of Registrable Securities covered by the registration statement and each underwriter or agent participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made with FINRA;

(xviii)      use its reasonable best efforts to make available the executive officers of the Company to participate with the holders of Registrable Securities and any underwriters in any “road shows” or other selling efforts that may be reasonably requested by the Holders in connection with the methods of distribution for the Registrable Securities;

(xix)        in the case of any underwritten offering, use its reasonable best efforts to obtain one or more cold comfort letters from the Company’s independent public accountants in customary form and covering such matters of the type customarily covered

15

by cold comfort letters as the holders of a majority of the Registrable Securities being sold reasonably request;

(xx)         in the case of any underwritten offering, use its reasonable best efforts to provide a legal opinion of the Company’s outside counsel, dated the effective date of such registration statement (and, if such registration includes an underwritten Public Offering, dated the date of the closing under the underwriting agreement), the registration statement, each amendment and supplement thereto, the prospectus included therein (including the preliminary prospectus) and such other documents relating thereto in customary form and covering such matters of the type customarily covered by legal opinions of such nature, which opinion shall be addressed to the underwriters and the holders of such Registrable Securities;

(xxi)        if the Company files an Automatic Shelf Registration Statement covering any Registrable Securities, use its best efforts to remain a WKSI (and not become an ineligible issuer (as defined in Rule 405 under the Securities Act)) during the period during which such Automatic Shelf Registration Statement is required to remain effective;

(xxii)       if the Company does not pay the filing fee covering the Registrable Securities at the time an Automatic Shelf Registration Statement is filed, pay such fee at such time or times as the Registrable Securities are to be sold; and

(xxiii)      if the Automatic Shelf Registration Statement has been outstanding for at least three (3) years, at the end of the third year, refile a new Automatic Shelf Registration Statement covering the Registrable Securities, and, if at any time when the Company is required to re-evaluate its WKSI status the Company determines that it is not a WKSI, use its best efforts to refile the Shelf Registration Statement on Form S-3 and, if such form is not available, Form S-1 and keep such registration statement effective during the period during which such registration statement is required to be kept effective.

(b)   Any officer of the Company who is a holder of Registrable Securities agrees that if and for so long as he or she is employed by the Company or any Subsidiary thereof, he or she shall participate fully in the sale process in a manner customary for persons in like positions and consistent with his or her other duties with the Company, including the preparation of the registration statement and the preparation and presentation of any road shows.

(c)   The Company may require each seller of Registrable Securities as to which any registration is being effected to furnish the Company such information regarding such seller and the distribution of such securities as the Company may from time to time reasonably request in writing.

(d)   If NRG or any of its Affiliates seek to effectuate an in-kind distribution of all or part of their respective Registrable Securities to their respective direct or indirect equityholders, the Company shall, subject to any applicable lock-ups, work with the foregoing persons to facilitate such in-kind distribution in the manner reasonably requested.

16

Section 6.      Registration Expenses.

(a)   The Company’s Obligation.  All expenses incident to the Company’s performance of or compliance with this Agreement (including, without limitation, all registration, qualification and filing fees, fees and expenses of compliance with securities or blue sky laws, printing expenses, messenger and delivery expenses, fees and disbursements of custodians, and fees and disbursements of counsel for the Company and all independent certified public accountants, underwriters (excluding underwriting discounts and commissions) and other Persons retained by the Company) (all such expenses being herein called “Registration Expenses”), shall be borne as provided in this Agreement, except that the Company shall, in any event, pay its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit or quarterly review, the expense of any liability insurance and the expenses and fees for listing the securities to be registered on each securities exchange on which similar securities issued by the Company are then listed.  Each Person that sells securities pursuant to a Demand Registration or Piggyback Registration hereunder shall bear and pay all underwriting discounts and commissions applicable to the securities sold for such Person’s account.

(b)   Counsel Fees and Disbursements.  In connection with each Demand Registration, each Piggyback Registration and each Shelf Offering that is an underwritten Public Offering, the Company shall reimburse the holders of Registrable Securities included in such registration for the reasonable fees and disbursements of one counsel chosen by the holders of a majority of the Registrable Securities included in such registration or participating in such Shelf Offering and disbursements of each additional counsel retained by any holder of Registrable Securities for the purpose of rendering a legal opinion on behalf of such Holder in connection with any underwritten Demand Registration, Piggyback Registration or Shelf Offering.

Section 7.      Indemnification and Contribution.

(a)   By the Company.  The Company shall indemnify and hold harmless, to the extent permitted by law, each holder of Registrable Securities, such Holder’s officers, directors, managers, employees, agents and representatives, and each Person who controls such Holder (within the meaning of the Securities Act) (the “Indemnified Parties”) against all losses, claims, actions, damages, liabilities and expenses (including with respect to actions or proceedings, whether commenced or threatened, and including reasonable attorney fees and expenses) caused by, resulting from, arising out of, based upon or related to any of the following statements, omissions or violations (each a “Violation”) by the Company:  (i) any untrue or alleged untrue statement of material fact contained in (A) any registration statement, prospectus, preliminary prospectus or Free-Writing Prospectus, or any amendment thereof or supplement thereto or (B) any application or other document or communication (in this Section 7, collectively called an “application”) executed by or on behalf of the Company or based upon written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify any securities covered by such registration under the securities laws thereof, (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any violation or alleged violation by the Company of the Securities Act or any other similar federal or state securities laws or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction required of

17

the Company in connection with any such registration, qualification or compliance.  In addition, the Company will reimburse such Indemnified Party for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such losses.  Notwithstanding the foregoing, the Company shall not be liable in any such case to the extent that any such losses result from, arise out of, are based upon, or relate to an untrue statement or alleged untrue statement, or omission or alleged omission, made in such registration statement, any such prospectus, preliminary prospectus or Free-Writing Prospectus or any amendment or supplement thereto, or in any application, in reliance upon, and in conformity with, written information prepared and furnished in writing to the Company by such Indemnified Party expressly for use therein or by such Indemnified Party’s failure to deliver a copy of the registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such Indemnified Party with a sufficient number of copies of the same.  In connection with an underwritten offering, the Company shall indemnify such underwriters, their officers and directors, and each Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the Indemnified Parties.

(b)   By Each Security Holder.  In connection with any registration statement in which a holder of Registrable Securities is participating, each such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such registration statement or prospectus and, to the extent permitted by law, shall indemnify the Company, its officers, directors, managers, employees, agents and representatives, and each Person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses resulting from any untrue or alleged untrue statement of material fact contained in the registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder; provided that the obligation to indemnify shall be individual, not joint and several, for each holder and shall be limited to the net amount of proceeds received by such Holder from the sale of Registrable Securities pursuant to such registration statement.

(c)   Claim Procedure.  Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall impair any Person’s right to indemnification hereunder only to the extent such failure has prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party.  If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld, conditioned or delayed).  An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified

18

parties with respect to such claim. In such instance, the conflicted indemnified parties shall have a right to retain one separate counsel, chosen by the holders of a majority of the Registrable Securities included in the registration if such Holders are indemnified parties, at the expense of the indemnifying party.

(d)   Contribution.  If the indemnification provided for in this Section 7 is held by a court of competent jurisdiction to be unavailable to, or is insufficient to hold harmless, an indemnified party or is otherwise unenforceable with respect to any loss, claim, damage, liability or action referred to herein, then the indemnifying party shall contribute to the amounts paid or payable by such indemnified party as a result of such loss, claim, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other hand in connection with the statements or omissions which resulted in such loss, claim, damage, liability or action as well as any other relevant equitable considerations; provided that the maximum amount of liability in respect of such contribution shall be limited, in the case of each seller of Registrable Securities, to an amount equal to the net proceeds actually received by such seller from the sale of Registrable Securities effected pursuant to such registration.  The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  The parties hereto agree that it would not be just or equitable if the contribution pursuant to this Section 7(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account such equitable considerations.  The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to herein shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending against any action or claim which is the subject hereof.  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 is not guilty of such fraudulent misrepresentation.

(e)   Release.  No indemnifying party shall, except with the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term thereof giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(f)    Non-exclusive Remedy; Survival.  The indemnification and contribution provided for under this Agreement shall be in addition to any other rights to indemnification or contribution that any indemnified party may have pursuant to law or contract and shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and shall survive the transfer of Registrable Securities and the termination or expiration of this Agreement.

Section 8.      Underwritten Offerings.

(a)   Participation.  No Person may participate in any offering hereunder which is underwritten unless such Person (i) agrees to sell such Person’s securities on the basis provided

19

in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve such arrangements (including, without limitation, pursuant to any over-allotment or “green shoe” option requested by the underwriters; provided that no holder of Registrable Securities shall be required to sell more than the number of Registrable Securities such Holder has requested to include) and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements.  Each holder of Registrable Securities shall execute and deliver such other agreements as may be reasonably requested by the Company and the lead managing underwriter(s) that are consistent with such Holder’s obligations under Section 4, Section 5 and this Section 8(a) or that are necessary to give further effect thereto.  To the extent that any such agreement is entered into pursuant to, and consistent with, Section 4 and this Section 8(a), the respective rights and obligations created under such agreement shall supersede the respective rights and obligations of the Holders, the Company and the underwriters created pursuant to this Section 8(a).

(b)   Price and Underwriting Discounts.  In the case of an underwritten Demand Registration or Underwritten Takedown requested by Holders pursuant to this Agreement, the price, underwriting discount and other financial terms of the related underwriting agreement for the Registrable Securities shall be determined by the Holders of a majority of the Registrable Securities included in such underwritten offering.

(c)   Suspended Distributions.  Each Person that is participating in any registration under this Agreement, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 5(a)(vi), shall immediately discontinue the disposition of its Registrable Securities pursuant to the registration statement until such Person’s receipt of the copies of a supplemented or amended prospectus as contemplated by Section 5(a)(vi). In the event the Company has given any such notice, the applicable time period set forth in Section 5(a)(ii) during which a Registration Statement is to remain effective shall be extended by the number of days during the period from and including the date of the giving of such notice pursuant to this Section 8(c) to and including the date when each seller of Registrable Securities covered by such registration statement shall have received the copies of the supplemented or amended prospectus contemplated by Section 5(a)(vi).

Section 9.      Additional Parties; Joinder.  Subject to the prior written consent of the holders of a majority of the Registrable Securities, the Company may permit any Person who acquires Common Stock or rights to acquire Common Stock from the Company after the date hereof to become a party to this Agreement and to succeed to all of the rights and obligations of a “holder of Registrable Securities” under this Agreement by obtaining an executed joinder to this Agreement from such Person in the form of Exhibit A attached hereto (a “Joinder”).  Upon the execution and delivery of a Joinder by such Person, the Common Stock or Class B common units of Yield LLC acquired by such Person (the “Acquired Common”) shall constitute Registrable Securities and such Person shall be a Holder of Registrable Securities under this Agreement with respect to the Acquired Common, and the Company shall add such Person’s name and address to the Schedule of Investors hereto and circulate such information to the parties to this Agreement.

20

Section 10.    Current Public Information.  At all times after the Company has filed a registration statement with the Securities and Exchange Commission pursuant to the requirements of either the Securities Act or the Exchange Act, the Company shall file all reports required to be filed by it under the Securities Act and the Exchange Act and shall take such further action as any holder or holders of Registrable Securities may reasonably request, all to the extent required to enable such Holders to sell Registrable Securities pursuant to Rule 144.  Upon request, the Company shall deliver to any holder of Restricted Securities a written statement as to whether it has complied with such requirements.

Section 11.    Subsidiary Public Offering.  If, after an initial Public Offering of the Capital Stock of one of its Subsidiaries (including Yield LLC), the Company distributes securities of such Subsidiary to its equity holders, then the rights and obligations of the Company pursuant to this Agreement shall apply, mutatis mutandis, to such Subsidiary, and the Company shall cause such Subsidiary to comply with such Subsidiary’s obligations under this Agreement.

Section 12.    Transfer of Registrable Securities.

(a)   Restrictions on Transfers.  Notwithstanding anything to the contrary contained herein, except in the case of (i) a transfer to the Company, (ii) a transfer by NRG to its stockholders, (iii) a Public Offering, (iv) a sale pursuant to Rule 144 after the completion of the Company’s initial Public Offering or (v) a transfer in connection with a Sale of the Company, prior to transferring any Registrable Securities to any Person (including, without limitation, by operation of law), the transferring Holder shall cause the prospective transferee to execute and deliver to the Company a Joinder agreeing to be bound by the terms of this Agreement.  Any transfer or attempted transfer of any Registrable Securities in violation of any provision of this Agreement shall be void, and the Company shall not record such transfer on its books or treat any purported transferee of such Registrable Securities as the owner thereof for any purpose.

(b)   Legend.  Each certificate evidencing any Registrable Securities and each certificate issued in exchange for or upon the transfer of any Registrable Securities (unless such Registrable Securities would no longer be Registrable Securities after such transfer) shall be stamped or otherwise imprinted with a legend in substantially the following form:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER AND OTHER PROVISIONS SET FORTH IN A REGISTRATION RIGHTS AGREEMENT DATED AS OF                           , 2013 AMONG THE ISSUER OF SUCH SECURITIES (THE “COMPANY”) AND CERTAIN OF THE COMPANY’S STOCKHOLDERS, AS AMENDED.  A COPY OF SUCH REGISTRATION RIGHTS AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE COMPANY TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”

The Company shall imprint, and shall cause Yield LLC to imprint, such legend on certificates evidencing Registrable Securities outstanding prior to the date hereof.  The legend set forth

21

above shall be removed from the certificates evidencing any securities that have ceased to be Registrable Securities.

Section 13.    General Provisions.

(a)   Amendments and Waivers.  Except as otherwise provided herein, the provisions of this Agreement may be amended, modified or waived only with the prior written consent of the Company and holders of a majority of the Registrable Securities; provided that no such amendment, modification or waiver that would materially and adversely affect a Holder or group of holders of Registrable Securities in a manner materially different than any other Holder or group of holders of Registrable Securities (other than amendments and modifications required to implement the provisions of Section 9), shall be effective against such Holder or group of holders of Registrable Securities without the consent of the holders of a majority of the Registrable Securities that are held by the group of Holders that is materially and adversely affected thereby.  The failure or delay of any Person to enforce any of the provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such Person thereafter to enforce each and every provision of this Agreement in accordance with its terms.  A waiver or consent to or of any breach or default by any Person in the performance by that Person of his, her or its obligations under this Agreement shall not be deemed to be a consent or waiver to or of any other breach or default in the performance by that Person of the same or any other obligations of that Person under this Agreement.

(b)   Remedies.  The parties to this Agreement shall be entitled to enforce their rights under this Agreement specifically (without posting a bond or other security), to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other rights existing in their favor.  The parties hereto agree and acknowledge that a breach of this Agreement would cause irreparable harm and money damages would not be an adequate remedy for any such breach and that, in addition to any other rights and remedies existing hereunder, any party shall be entitled to specific performance and/or other injunctive relief from any court of law or equity of competent jurisdiction (without posting any bond or other security) in order to enforce or prevent violation of the provisions of this Agreement.

(c)   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, invalid, illegal or unenforceable in any respect under any applicable law or regulation in any jurisdiction, such prohibition, invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of any other provision of this Agreement in such jurisdiction or in any other jurisdiction, but this Agreement shall be reformed, construed and enforced in such jurisdiction as if such prohibited, invalid, illegal or unenforceable provision had never been contained herein.

(d)   Entire Agreement.  Except as otherwise provided herein, this Agreement contains the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersedes and preempts any prior understandings, agreements or representations by or among the parties hereto, written or oral, which may have related to the subject matter hereof in any way.

22

(e)   Successors and Assigns.  This Agreement shall bind and inure to the benefit and be enforceable by the Company and its successors and assigns and the holders of Registrable Securities and their respective successors and assigns (whether so expressed or not).  In addition, whether or not any express assignment has been made, the provisions of this Agreement which are for the benefit of purchasers or holders of Registrable Securities are also for the benefit of, and enforceable by, any subsequent holder of Registrable Securities.

(f)    Notices.  Any notice, demand or other communication to be given under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given (i) when delivered personally to the recipient, (ii) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient; but if not, then on the next Business Day, (iii) one Business Day after it is sent to the recipient by reputable overnight courier service (charges prepaid) or (iv) three Business Days after it is mailed to the recipient by first class mail, return receipt requested.  Such notices, demands and other communications shall be sent to the Company at the address specified below and to any holder of Registrable Securities or to any other party subject to this Agreement at such address as indicated on Schedule of Investors hereto, or at such address or to the attention of such other Person as the recipient party has specified by prior written notice to the sending party.  Any party may change such party’s address for receipt of notice by giving prior written notice of the change to the sending party as provided herein.  The Company’s address is:
