(c)                                  Subject to the terms and conditions hereof (including the remainder of this Section 3.1) and the other Transaction Documents, and only to the extent required under the Antitrust Laws, each of the parties shall use its commercially reasonable efforts to avoid or eliminate each and every impediment under any Antitrust Laws that may be asserted by any Governmental Entity, so as to enable the parties to give effect to the transactions contemplated hereby and by the other Transaction Documents in accordance with the terms hereof and thereof; provided, that notwithstanding anything to the contrary contained herein or in any of the other Transaction Documents, nothing in this Section 3.1 shall require, or be construed to require, any party or any of its Affiliates to agree to (and no party or any of its Affiliates shall agree to, without the prior written consent of the other parties):  (i) sell, hold separate, divest, discontinue or limit (or any conditions relating to, or changes or restrictions in, the operation of) any assets, businesses or interests of it or its Affiliates (irrespective of whether or not such assets, businesses or interests are related to, are the subject matter of or could be affected by the transactions contemplated by the Transaction Documents); (ii) without limiting clause (i) in any respect, any conditions relating to, or changes or restrictions in, the operations of any such assets, businesses or interests that would reasonably be expected to adversely impact (x) the business of, or the financial, business or strategic benefits of the transactions contemplated hereby or by any of the other Transaction Documents to it or its Affiliates, or (y) any other assets, businesses or interests of it or its Affiliates; or (iii) without limiting clause (i) in any respect, any modification or waiver of the terms and conditions of this Agreement or any of the other Transaction Documents that would reasonably be expected to adversely impact (x) the business of, or financial, business or strategic benefits of the transactions contemplated hereby or by any of the other Transaction Documents to it or its Affiliates, or (y) any other assets, businesses or interests of it or its Affiliates.

(d)                                 Walmart shall have the principal responsibility for devising and implementing the strategy (including with respect to the timing of filings) for obtaining any exemptions, authorizations, consents or approvals required under the HSR Act or any other Antitrust Laws in connection with the transactions contemplated hereby and by the other Transaction Documents; provided, however, that Walmart shall consult in advance with the Company and in good faith take the Company’s views into account regarding the overall antitrust strategy.  Each of the parties shall promptly notify the other party of, and if in writing furnish the other with copies of (or, in the case of oral communications, advise the other of), any substantive communication that it or any of its Affiliates receives from any Governmental Entity, whether written or oral, relating to the matters that are the subject of this Agreement or any of the other Transaction Documents and, to the extent reasonably practicable, permit the other party to review in advance any proposed substantive written communication by such party to any Governmental Entity and consider in good faith the other party’s reasonable comments on any

13

such proposed substantive written communications prior to their submission.  No party shall, and each party shall cause its Affiliates not to, participate or agree to participate in any substantive meeting or communication with any Governmental Entity in respect of the subject matter of the Transaction Documents, including on a “no names” or hypothetical basis, unless (to the extent practicable) it or they consult with the other party in advance and, to the extent practicable and permitted by such Governmental Entity, give the other party the opportunity to jointly prepare for, attend and participate in such meeting or communication.  The parties shall (and shall cause their Affiliates to) coordinate and cooperate fully with each other in exchanging such information and providing such assistance as the other party may reasonably request in connection with the matters described in this Section 3.1, including (x) furnishing to each other all information reasonably requested to determine the jurisdictions in which a filing or submission under any Antitrust Law is required or advisable, (y) furnishing to each other all information required for any filing or submission under any Antitrust Law and (z) keeping each other reasonably informed with respect to the status of each exemption, authorization, consent, approval, filing and notice under any Antitrust Law, in each case, in connection with the matters that are the subject of this Agreement or any of the other Transaction Documents.  The parties shall provide each other with copies of all substantive correspondence, filings or communications between them or any of their Affiliates or Representatives, on the one hand, and any Governmental Entity or members of its staff, on the other hand, relating to the matters that are the subject of this Agreement or any of the other Transaction Documents; provided that such material may be redacted as necessary to (1) comply with contractual arrangements, (2) address good faith legal privilege or confidentiality concerns and (3) comply with Applicable Law.

(e)                                  Subject to the other provisions of this Agreement, including in this Section 3.1, in the event that any arbitral, administrative, judicial or analogous action, claim or proceeding is instituted (or threatened to be instituted) by a Governmental Entity or any other party challenging the transactions contemplated hereby or by any of the other Transaction Documents (“Transaction Litigation”), neither party shall be required to contest and resist any such Transaction Litigation or to seek to have vacated, lifted, reversed or overturned any judgment, ruling, order, writ, injunction or decree, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation or implementation of the transactions contemplated hereby or by any of the other Transaction Documents.  Each party shall keep the other party reasonably informed with respect to any Transaction Litigation unless doing so would reasonably be likely to jeopardize any privilege of such party regarding any such Transaction Litigation (subject to such party using commercially reasonable efforts to, and cooperating in good faith with the other party in, developing and implementing reasonable alternative arrangements to provide such other party with such information).  Subject to the immediately preceding sentence, each party shall promptly advise the other party orally and in writing in connection with, and shall consult with each other with respect to, any Transaction Litigation and shall in good faith give consideration to each other’s advice with respect to such Transaction Litigation.

(f)                                   As promptly as practicable following the date hereof, the Company shall adopt such amendments and take such further actions and do or cause to be done all things necessary, proper or advisable under Applicable Law, to prevent the execution and delivery of the Transaction Documents and the consummation of the transactions contemplated thereby from

14

constituting a “change in control,” “change of control” or other similar term under any Company Benefit Plan.

(g)                                  Notwithstanding anything herein to the contrary, from and after the earlier of (i) the exercise of the Warrant in full and (ii) the expiration, termination or cancellation of the Warrant without the Warrant having been exercised in full, no party shall have any further obligations under this Section 3.1; provided, that this Section 3.1(g) shall in no way relieve any party with respect to any breach by such party of this Section 3.1 prior to such time.

(a)                                 The parties acknowledge that the joint press release regarding the initial announcement of the transactions contemplated by this Agreement and the other Transaction Documents to customers, suppliers, investors and employees and otherwise has been agreed by the parties.  The parties further acknowledge and agree that the Company may use Walmart’s name as required pursuant to any requirement or request of the Commission or any other Governmental Entity.

(b)                                 Without limiting the foregoing, in recognition of the importance to the Company and Walmart of taking appropriate steps to maintain the confidentiality of agreements between the parties from the parties’ customers, competitors and suppliers, in the event that the Company is legally required to file or otherwise submit any agreement to which Walmart is a party (each a “Disclosable Agreement”) or any excerpt from, summary of or information relating to any Disclosable Agreement with or to the Commission or any other regulatory body or stock exchange (each, a “Disclosure Agency”) the filing or submission of which involves or could result in public disclosure of such Disclosable Agreement or excerpt therefrom, summary thereof or information relating thereto, the Company will (1) promptly notify Walmart of such requirement to file or otherwise submit the Disclosable Agreement or any excerpt therefrom, summary thereof or information relating thereto and any applicable deadline for making such filing or submission, (2) provide Walmart with a reasonable opportunity to request (i) a redaction of all information in the Disclosable Agreement or excerpt therefrom, summary thereof or information relating thereto, as requested by Walmart (in addition to any redactions proposed by the Company) prior to filing or submitting such Disclosable Agreement, excerpt therefrom, summary thereof or information relating thereto, and (ii) the submission of one or more confidential treatment requests in support of such redactions with such arguments as requested by Walmart, including in response to any comments or requests for information issued by the Commission or the applicable Disclosure Agency, to which, in each case, the Company shall agree absent a reasonable basis for objection (and shall provide Walmart prompt notice of any such objection, the basis therefor and a reasonable opportunity to consider and discuss such objection with the Company), (3) provide Walmart (i) with copies of any comments and all other communications received from the Commission or the applicable Disclosure Agency with respect to the Disclosable Agreement or confidential treatment thereof (including a reasonable summary of any oral communications or other comments received other than in writing) as promptly as reasonably practicable and (ii) with the Company’s proposed response to such comments at least three (3) Business Days before such response is submitted to the Commission or the applicable Disclosure Agency, and (4) provide Walmart with a reasonable opportunity to propose revisions within such three (3) Business Day-period to such the Company’s proposed

15

response as requested by Walmart, and which revisions the Company shall make absent a reasonable basis for objection (and shall provide Walmart prompt notice of any such objection, the basis therefor and a reasonable opportunity to consider and discuss such objection with the Company), and, as applicable, use its commercially reasonable efforts in responding to any such comments in order to pursue assurance that confidential treatment will be granted.  The Company will not file this Agreement, any Disclosable Agreement, any excerpt therefrom, summary or portion thereof or information relating thereto with any governmental authority or regulatory body, including the Commission or any Disclosure Agency, or disclose any other Confidential Information in any manner, except to the extent (i) permitted above, or (ii) the Company determines in good faith based on the written advice of outside counsel that making such filing or submission without adhering to the requirements set forth above is necessary to comply with Applicable Law.  Notwithstanding anything in Section 8.1 of this Agreement to the contrary, the provisions of this Section 3.2(b) will survive for so long as the Power Purchase Agreement has not been terminated.

3.3                               Expenses.  Unless otherwise provided in any Transaction Document, each of the parties shall bear and pay all costs and expenses incurred by it or on its behalf in connection with the transactions contemplated under the Transaction Documents, including fees and expenses of its own financial or other consultants, investment bankers, accountants and counsel.

(i)            by Walmart (x) to any of its Affiliates or (y) to its or its Affiliate’s respective directors, managers, officers, employees and authorized Representatives (including attorneys, accountants, consultants, bankers and financial advisors thereof) (each of the Persons described in clauses (x) and (y), collectively, for purposes of this Section 5.1(d) and the definition of Confidential Information, “Representatives” of Walmart), in each case, solely if and to the extent any such Person needs to be provided such Confidential Information to assist Walmart or its Affiliates in (A) evaluating or reviewing its existing investment, or, with respect to the exercise of the Warrant, its prospective investment, in the Company, including in connection with the disposition thereof or voting shares of Common Stock or (B) evaluating, making or submitting, or otherwise taking any action in furtherance of, an Acquisition Proposal permitted by Section 5.3.  Each Representative shall be deemed to be bound by the provisions of this Section 5.1(d) and Walmart shall be responsible for any breach of this Section 5.1(d) (or such other agreement or obligation, as applicable) by any of its Representatives;

(iv)          by Walmart or any of its Representatives to the extent that Walmart or such Representative has been advised by its counsel that such disclosure is required to be made by it under Applicable Law or by a Governmental Entity; provided, that prior to making such disclosure, such Person uses commercially reasonable efforts to preserve the confidentiality of the Confidential Information to the extent permitted by Applicable Law, including, to the extent practicable and permitted by Applicable Law, consulting with the Company regarding such disclosure and, if reasonably requested by the Company, assisting the Company, at the Company’s expense, in seeking a protective

22

order to prevent the requested disclosure; provided, further, that Walmart or such Representative, as the case may be, uses commercially reasonable efforts to disclose only that portion of the Confidential Information as is requested by the applicable Governmental Entity or as is, based on the advice of its counsel, legally required or compelled; and provided, further, that the parties hereto expressly agree that notwithstanding anything in the Confidentiality Agreement or any other confidentiality agreement between or among the Company, Walmart or its Affiliates or Representatives, to the contrary, any Confidential Information that is permitted to be disclosed or used in any manner pursuant to this Agreement can be so disclosed or used. Notwithstanding the foregoing, Walmart or its Representatives, as the case may be, may only disclose Confidential Information pursuant to this Section 5.1(d)(iv) if the request or requirement for such disclosure does not arise from, is not in connection with, and/or is not related to, a breach of Section 5.3 hereof.

5.2          Tax Reporting Requirements.

(a)           The Company will provide Walmart with any information reasonably requested by Walmart and within the Company’s possession or that can be provided with the use of reasonable efforts, to allow Walmart to comply with Applicable Law related to taxes or to avail itself of any provision of Applicable Law related to taxes.

(i)            acquire, agree to acquire, propose or offer to acquire, by purchase or otherwise, Equity Securities or Derivative Instruments or debt securities of the Company, other than:

(A)          Warrant Shares acquired by Walmart in accordance with this Agreement;

(ii)           make, or in any way participate or engage in, any “solicitation” of “proxies” (as such terms are used in the proxy rules of the Commission) (whether or not relating to the election or removal of directors) to vote any Voting Securities, or disclose how Walmart intends to vote its Warrant Shares on any contested election of directors or any contested proposal relating to an Acquisition Proposal unless such disclosure is determined by Walmart in good faith, based on the advice of its legal counsel, to be reasonably required by Applicable Law;

(iii)          call, or seek to call, a meeting of the stockholders of the Company or initiate any stockholder proposal for action by stockholders of the Company;

(iv)          nominate or seek to nominate, directly or indirectly, any person to the Board;

(vi)          make any public announcement with respect to, enter, agree to enter, propose or offer to enter into any merger, business combination, recapitalization, restructuring, change in control transaction or other similar extraordinary transaction involving the securities of the Company or any of its subsidiaries, or purchase of a material portion of the assets, properties or Equity Securities of the Company, other than acquisitions of Equity Securities as follows:

(C)          pursuant to and in accordance with Section 4.4(b)(i); or

(D)          Equity Securities of the Company representing less than 5% of the outstanding shares of Common Stock held by a Person acquired by Walmart or its Affiliates; provided that such Equity Securities of the Company were acquired by such acquired Person prior to it entering into an agreement with Walmart to be acquired and not in contemplation of, or in connection with, Walmart’s  acquisition of such Person and Walmart agrees to dispose of those Equity Securities and to reasonably cooperate with the Company to establish a reasonable time table and other reasonable parameters for so doing so as to minimize the impact of such disposition on the trading market for the Common Stock; provided that in connection with such disposition, Walmart shall not be

24

required to take any action that would be likely to adversely affect the value of the Equity Securities.

(vii)         otherwise act, alone or in concert with others, to seek to control or influence the management or the policies of the Company (for the avoidance of doubt, excluding any such act to the extent in its capacity as a commercial counterparty, customer, supplier, industry participant or the like);

(x)           form, join or in any way participate in a Group (other than with its subsidiary that is bound by the restrictions of this Section 5.3(a) or a Group that consists solely of Walmart and/or any of its Affiliates), with respect to any Voting Securities or otherwise in connection with any of the foregoing; or

(xi)          publicly disclose any intention, plan or proposal with respect to any of the foregoing.

For the avoidance of doubt, this Section 5.3 shall not prohibit Walmart from exercising any rights or taking any action under the Power Purchase Agreement.  In addition, Walmart shall not, directly or indirectly, and shall not permit any of its subsidiaries, directly or indirectly, to, contest the validity of this Section 5.3 or, subject to Section 5.3(b), seek a waiver, amendment or release of any provisions of this Section 5.3 (including this sentence) (whether by legal action or otherwise).

(b)           Notwithstanding anything to the contrary contained herein or in any of the other Transaction Documents, including Section 5.3(a) hereof, Walmart shall not be prohibited or restricted from making and submitting to the Company and/or the Board, any Acquisition Proposal that is not intended to require the Company to disclose such proposal, or any confidential request for the Company and/or the Board to waive, amend or provide a release of any provision of this Section 5.3 (whether or not in connection with such Acquisition Proposal); provided that any such Acquisition Proposal and/or confidential request shall by its terms terminate if it is publicly disclosed or announced by Walmart (except in the event that such public disclosure is required by Applicable Law) without the prior approval of the Board.  If the Company (through the Board or otherwise) shall have commenced a process to solicit Acquisition Proposals from third parties, then the Company will promptly notify Walmart of such determination and any information provided to Walmart in connection with such notice, including, without limitation, the fact that the Company has provided such notice to Walmart, shall be kept confidential by Walmart, except to the extent information is permitted to be disclosed or used by Section 5.1(d).

25

(c)           Notwithstanding anything to the contrary herein, the provisions of this Section 5.3 shall become void and of no further force and effect upon (i) the public announcement by the Company that it has entered into a definitive agreement with a Person other than Walmart or any of its Affiliates for a transaction involving a Business Combination or (ii) if any Person other than Walmart or any of its Affiliates commences a tender or exchange offer which, if consummated, would constitute a Business Combination; provided, however, that with respect to clauses (i) and (ii) of this sentence, Walmart shall not have materially breached any of the provisions of this Section 5.3.

(d)           An “Walmart Standstill Termination Event” shall be deemed to occur if, as of the end of any Business Day following the date of this Agreement, Walmart and its Affiliates Beneficially Own shares of Common Stock collectively representing less than ten percent (10%) of the Common Stock; provided, however, that if the Beneficial Ownership of Walmart and its Affiliates collectively represents at least ten percent (10%) of the Common Stock at any time within one year following such occurrence, then the provisions of this Section 5.3 shall automatically again become applicable to Walmart.

5.4          Voting Obligation.

(a)           At all times during the Standstill Period, Walmart shall be entitled to vote (including, if applicable, through the execution of one or more written consents if stockholders of the Company are requested to vote through the execution of an action by written consent in lieu of any such annual or special meeting of stockholders of the Company) the shares of Common Stock owned by it or its Affiliates or over which it or its Affiliates have the ability to vote, up to 14.9% of the Company’s outstanding shares of Common Stock (the “Voting Threshold”), in its sole and absolute discretion; provided that if at any time Walmart and its Affiliates collectively have the ability to vote more than 14.9% of the Company’s outstanding shares of Common Stock, then in connection with each meeting of the Company’s stockholders Walmart shall cause all of the shares of Common Stock in excess of the Voting Threshold owned by it or any of its Affiliates or over which it or any of its Affiliates have the ability to vote to be present for purposes of determining quorum at such meeting.  At all times during the Standstill Period, Walmart shall cause the shares of Common Stock owned by it or any of its Affiliates or over which it or any of its Affiliates have the ability to vote in excess of the Voting Threshold to be voted (including, if applicable, through the execution of one or more written consents if stockholders of the Company are requested to vote through the execution of an action by written consent in lieu of any such annual or special meeting of stockholders of the Company) in accordance with the recommendation of the Board, including without limitation, in favor of all those persons nominated to serve as directors of the Company by the Board or its Nominating and Governance Committee.

(b)           At any time Walmart or any of its Affiliates own shares of Common Stock for which they have the ability to vote and Walmart is subject to the voting requirements of Section 5.3(a), Walmart hereby appoints the Company, including without limitation its Chief Executive Officer and Chairman of the Board and any other designee of the Company or of such officer, and each of them individually, its proxy and attorney-in-fact, with full power of substitution and resubstitution, to vote or act by written consent during the term of this Agreement with respect to shares of Common Stock in excess of the Voting Threshold over

26

which Walmart or any of its Affiliates have the ability to vote, to be counted for purposes of determining quorum at any meeting of stockholders and to be voted in accordance with Section 5.4(a). This proxy and power of attorney is given to secure the performance of the obligations of Walmart under this Agreement. Walmart shall take such further action or execute such other instruments as may be necessary to effectuate the intent of this proxy; this proxy and power of attorney granted by Walmart shall be irrevocable during the term of this Agreement (but subject to Section 5.4(a)), shall be deemed to be coupled with an interest sufficient under Applicable Law to support an irrevocable proxy and shall revoke any and all prior proxies granted by Walmart with respect to shares of Common Stock. The power of attorney granted by Walmart herein is a durable power of attorney and shall survive the dissolution or bankruptcy of Walmart.

5.5          Survival.  Notwithstanding anything in this Agreement, this Article V (other than Section 5.3) shall survive termination of this Agreement pursuant to Section 8.1, and will continue until the date that the Beneficial Ownership of Walmart, in the aggregate, of the Common Stock is less than two percent (2%), on a “fully diluted basis”; provided, that Section 5.2 shall survive with respect to the taxable year in which such date occurs.

ARTICLE VI

REGISTRATION

6.1          Demand Registrations.

(a)           Subject to the terms and conditions hereof, solely during any period that the Company is then ineligible under Applicable Law to register Registrable Securities on a registration statement on Form S-3 or any successor form thereto (“Form S-3”), or if the Company is so eligible but has failed to comply with its obligations under Section 6.3 any Demand Shareholders (“Requesting Shareholders”) shall be entitled to make no more than three (3) written requests of the Company (each, a “Demand”) for registration under the Securities Act of an amount of Registrable Securities then held by such Requesting Shareholders that equals or is greater than the Registrable Amount (a “Demand Registration” and such registration statement, a “Demand Registration Statement”); provided, however, that no Demand may be made by any Demand Shareholder prior to the date that is one hundred eighty (180) days after the date of Closing.  Thereupon, the Company shall, subject to the terms of this Agreement, file the registration statement no later than 30 days after receipt of a Demand and shall use its commercially reasonable efforts to effect the registration as promptly as practicable under the Securities Act of:

(i)            the Registrable Securities which the Company has been so requested to register by the Requesting Shareholders for disposition in accordance with the intended method of disposition stated in such Demand;

(ii)           all other Registrable Securities which the Company has been requested to register pursuant to Section 6.1(b), but subject to Section 6.1(g); and

27

(iii)          all shares of Common Stock which the Company may elect to register in connection with any offering of Registrable Securities pursuant to this Section 6.1, but subject to Section 6.1(g);

all to the extent necessary to permit the disposition (in accordance with the intended methods thereof) of the Registrable Securities and the additional shares of Common Stock, if any, to be so registered.

(b)           A Demand shall specify:  (i) the aggregate number of Registrable Securities requested to be registered in such Demand Registration, (ii) the intended method of disposition in connection with such Demand Registration, to the extent then known, and (iii) the identity of the Requesting Shareholder(s).  Within five (5) days after receipt of a Demand, the Company shall give written notice of such Demand to all other holders of Registrable Securities.  The Company shall include in the Demand Registration covered by such Demand all Registrable Securities with respect to which the Company has received a written request for inclusion therein within five (5) days after the Company’s notice required by this paragraph has been given, provided that if such five (5) day period ends on a day that is not a Business Day, such period shall be deemed to end on the next succeeding Business Day.  Each such written request shall comply with the requirements of a Demand as set forth in this Section 6.1(b).

(c)           A Demand Registration shall not be deemed to have been effected (i) unless the Demand Registration Statement with respect thereto has become effective and has remained effective for a period of at least one hundred five (105) days or such shorter period in which all Registrable Securities included in such Demand Registration have actually been sold or otherwise disposed of thereunder (provided, that such period shall be extended for a period of time equal to the period the holders of Registrable Securities refrain from selling any securities included in such registration statement at the request of the Company or the lead managing underwriter(s) pursuant to the provisions of this Agreement) or (ii) if, after it has become effective, such Demand Registration becomes subject, prior to one hundred five (105) days after effectiveness, to any stop order, injunction or other order or requirement of the Commission or other Governmental Entity, other than by reason of any act or omission by the applicable Selling Shareholders.

(d)           Demand Registrations shall be on such appropriate registration form of the Commission as shall be selected by the Company and reasonably acceptable to the Requesting Shareholders.

(e)           The Company shall not be obligated to (i) subject to Section 6.1(c), maintain the effectiveness of a registration statement under the Securities Act filed pursuant to a Demand Registration for a period longer than one hundred five (105) days or (ii) effect any Demand Registration (A) within ninety (90) days of a “firm commitment” Underwritten Offering in which all Demand Shareholders were offered “piggyback” rights pursuant to Section 6.2 (subject to Section 6.2(b)) and at least fifty percent (50%) of the number of Registrable Securities requested by such Demand Shareholders to be included in such Demand Registration were included, (B) within ninety (90) days of the completion of any other Demand Registration (including, for the avoidance of doubt, any Underwritten Offering pursuant to any Shelf Registration Statement), (C) within ninety (90) days of the completion of any other Underwritten

28

Offering by the Company or any shorter period during which the Company has agreed not to effect a registration or public offering of securities (in each case only to the extent that the Company has undertaken contractually to the underwriters of such Underwritten Offering not to effect any registration or public offering of securities), (D) if, in the Company’s reasonable judgment, it is not feasible for the Company to proceed with the Demand Registration because of the unavailability of audited or other required financial statements of the Company or any other Person; provided, that the Company shall use its commercially reasonable efforts to obtain such financial statements as promptly as practicable.

(f)            The Company shall be entitled to (i) postpone (upon written notice to the Demand Shareholders) the filing or the effectiveness of a registration statement for any Demand Registration, (ii) cause any Demand Registration Statement to be withdrawn and its effectiveness terminated and (iii) suspend the use of the prospectus forming the part of any registration statement, in each case in the event of a Blackout Period until the expiration of the applicable Blackout Period.  In the event of a Blackout Period under clause (ii) of the definition thereof, the Company shall deliver to the Demand Shareholders requesting registration a certificate signed by either the chief executive officer or the chief financial officer of the Company certifying that, in the good faith judgment of the Company, the conditions described in clause (ii) of the definition of Blackout Period are met.  Such certificate shall contain an approximation of the anticipated delay.  Upon notice by the Company to the Demand Shareholders of any such determination, each Demand Shareholder covenants that, subject to Applicable Law, it shall keep the fact of any such notice strictly confidential, and, in the case of a Blackout Period pursuant to clause (ii)(y) of the definition of Blackout Period, promptly halt any offer, sale, trading or other Transfer by it or any of its Affiliates of any Registrable Securities for the duration of the Blackout Period set forth in such notice (or until such Blackout Period shall be earlier terminated in writing by the Company) and promptly halt any use, publication, dissemination or distribution of the Demand Registration Statement, each prospectus included therein, and any amendment or supplement thereto by it and any of its Affiliates for the duration of the Blackout Period set forth in such notice (or until such Blackout Period shall be earlier terminated in writing by the Company) and, if so directed in writing by the Company, will deliver to the Company any copies then in the Demand Shareholder’s possession of the prospectus covering such Registrable Securities that was in effect at the time of receipt of such notice.

(g)           If, in connection with a Demand Registration that involves an Underwritten Offering, the lead managing underwriter(s) advise(s) the Company that, in its (their) good faith opinion, the inclusion of all of the securities sought to be registered in connection with such Demand Registration would adversely affect the success thereof, then the Company shall include in such registration statement only such securities as the Company is advised by such lead managing underwriter(s) can be sold without such adverse effect as follows and in the following order of priority: (i) first, up to the number of Registrable Securities requested to be included in such Demand Registration by the Demand Shareholders, which, in the opinion of the lead managing underwriter(s), can be sold without adversely affecting the success thereof, pro rata among such Demand Shareholders on the basis of the number of such Registrable Securities requested to be included by such Demand Shareholders; (ii) second, securities the Company proposes to sell; and (iii) third, all other securities of the Company duly requested to be included in such registration statement, pro rata on the basis of the amount of

29

such other securities requested to be included or such other allocation method determined by the Company.

(h)           Any time that a Demand Registration involves an Underwritten Offering, the Requesting Shareholder(s) shall select the investment banker(s) and manager(s) that will serve as managing underwriters (including which such managing underwriters will serve as lead or co-lead) and underwriters with respect to the offering of such Registrable Securities; provided, that such investment banker(s) and manager(s) shall be reasonably acceptable to the Company (such acceptance not to be unreasonably withheld, conditioned or delayed).

6.2          Piggyback Registrations.

(a)           Subject to the terms and conditions hereof, from and after the date that is one hundred eighty (180) days after the date of Closing, whenever the Company proposes to register any Common Stock (or any other securities that are of the same class or series as any Registrable Securities that are not shares of Common Stock) under the Securities Act (other than a registration by the Company (i) on Form S-4 or any successor form thereto, (ii) on Form S-8 or any successor form thereto, (iii) pursuant to Section 6.3, or (iv) pursuant to Section 6.1) (a “Piggyback Registration”), whether for its own account or for the account of others, the Company shall give all Demand Shareholders prompt written notice thereof (but not less than ten (10) Business Days prior to the filing by the Company with the Commission of any registration statement with respect thereto).  Such notice (a “Piggyback Notice”) shall specify the number of shares of Common Stock (or other securities, as applicable) proposed to be registered, the proposed date of filing of such registration statement with the Commission, the proposed means of distribution and the proposed managing underwriter(s) (if any) and a good faith estimate by the Company of the proposed minimum offering price of such shares of Common Stock (or other securities, as applicable), in each case to the extent then known.  Subject to Section 6.2(b), the Company shall include in each such Piggyback Registration all Registrable Securities held by Demand Shareholders (a “Piggyback Seller”) with respect to which the Company has received written requests (which written requests shall specify the number of Registrable Securities requested to be disposed of by such Piggyback Seller) for inclusion therein within ten (10) days after such Piggyback Notice is received by such Piggyback Seller.

(b)           If, in connection with a Piggyback Registration that involves an Underwritten Offering, the lead managing underwriter(s) advise(s) the Company that, in its opinion, the inclusion of all the securities sought to be included in such Piggyback Registration by (w) the Company, (x) other Persons who have sought to have shares of Common Stock registered in such Piggyback Registration pursuant to rights to demand (other than pursuant to so-called “piggyback” or other incidental or participation registration rights) such registration (such Persons being “Other Demanding Sellers”), (y) the Piggyback Sellers and (z) any other proposed sellers of shares of Common Stock (such Persons being “Other Proposed Sellers”), as the case may be, would materially and adversely affect the success thereof, then the Company shall include in the registration statement applicable to such Piggyback Registration only such securities as the Company is so advised by such lead managing underwriter(s) can be sold without such an effect, as follows and in the following order of priority:

30

(i)                                     if the Piggyback Registration relates to an offering for the Company’s own account, then (A) first, such number of shares of Common Stock (or other securities, as applicable) to be sold by the Company as the Company, in its reasonable judgment, shall have determined, (B) second, Registrable Securities of Piggyback Sellers, pro rata on the basis of the number of Registrable Securities proposed to be sold by such Piggyback Sellers, (C) third, shares of Common Stock sought to be registered by Other Demanding Sellers, pro rata on the basis of the number of shares of Common Stock proposed to be sold by such Other Demanding Sellers and (D) fourth, other shares of Common Stock proposed to be sold by any Other Proposed Sellers; or

(ii)                                  if the Piggyback Registration relates to an offering other than for the Company’s own account, then (A) first, such number of shares of Common Stock (or other securities, as applicable) sought to be registered by each Other Demanding Seller pro rata in proportion to the number of securities sought to be registered by all such Other Demanding Sellers, (B) second, Registrable Securities of Piggyback Sellers, pro rata on the basis of the number of Registrable Securities proposed to be sold by such Piggyback Sellers, (C) third, shares of Common Stock to be sold by the Company and (D) fourth, other shares of Common Stock proposed to be sold by any Other Proposed Sellers.

(c)                                  For clarity, in connection with any Underwritten Offering under this Section 6.2 for the Company’s account, the Company shall not be required to include the Registrable Securities of a Piggyback Seller in the Underwritten Offering unless such Piggyback Seller accepts the terms of the underwriting as agreed upon between the Company and the lead managing underwriter(s), which shall be selected by the Company.

(d)                                 If, at any time after giving written notice of its intention to register any shares of Common Stock (or other securities, as applicable) as set forth in this Section 6.2 and prior to the time the registration statement filed in connection with such Piggyback Registration is declared effective, the Company shall determine for any reason not to register such shares of Common Stock (or other securities, as applicable), the Company may, at its election, give written notice of such determination to the Piggyback Sellers within five (5) Business Days thereof and thereupon shall be relieved of its obligation to register any Registrable Securities in connection with such particular withdrawn or abandoned Piggyback Registration; provided, that, if permitted pursuant to Section 6.1, the Demand Shareholders may continue the registration as a Demand Registration pursuant to the terms of Section 6.1.

6.3                               Shelf Registration Statement.

(a)                                 Subject to the terms and conditions hereof, and further subject to the availability of Form S-3 to the Company, from and after the date that is one hundred eighty (180) days after the date of Closing, any of the Demand Shareholders may by written notice delivered to the Company (the “Shelf Notice”) require the Company to file as soon as reasonably practicable, and to use commercially reasonable efforts to cause to be declared effective by the Commission as soon as reasonably practicable after such filing date, a Form S-3, providing for an offering to be made on a continuous basis pursuant to Rule 415 under the Securities Act relating to the offer and sale, from time to time, of an amount of Registrable Securities then held by such Demand Shareholders that equals or is greater than the Registrable Amount (the “Shelf

31

Registration Statement”).  To the extent the Company is a well-known seasoned issuer (as defined in Rule 405 under the Securities Act), the Company shall file the Shelf Registration Statement in the form of an automatic shelf registration statement (as defined in Rule 405 under the Securities Act) or any successor form thereto.  If registering a number of Registrable Securities, the Company shall pay the registration fee for all Registrable Securities to be registered pursuant to an automatic shelf registration statement at the time of filing of the automatic shelf registration statement and shall not elect to pay any portion of the registration fee on a deferred basis.  The Company may also amend an existing registration statement on Form S-3, including by post-effective amendment, in order to fulfill its obligations hereunder.

(b)                                 Within five (5) days after receipt of a Shelf Notice pursuant to Section 6.3(a), the Company will deliver written notice thereof to all other holders of Registrable Securities.  Each other holder of Registrable Securities may elect to participate with respect to its Registrable Securities in the Shelf Registration Statement in accordance with the plan and method of distribution set forth, or to be set forth, in such Shelf Registration Statement by delivering to the Company a written request to so participate within five (5) days after the Shelf Notice is received by any such holder of Registrable Securities.

(c)                                  Subject to Section 6.3(d), the Company shall use its commercially reasonable efforts to keep the Shelf Registration Statement continuously effective until the date on which all Registrable Securities covered by the Shelf Registration Statement have been sold thereunder in accordance with the plan and method of distribution disclosed in the prospectus included in the Shelf Registration Statement, or otherwise cease to be Registrable Securities.

(d)                                 Notwithstanding anything to the contrary contained in this Agreement, the Company shall be entitled, from time to time, by providing written notice to the holders of Registrable Securities who elected to participate in the Shelf Registration Statement, to require such holders of Registrable Securities to suspend the use of the prospectus for sales of Registrable Securities under the Shelf Registration Statement during any Blackout Period.  In the event of a Blackout Period under clause (ii) of the definition thereof, the Company shall deliver to the Demand Shareholders requesting registration a certificate signed by either the chief executive officer or the chief financial officer of the Company certifying that, in the good faith judgment of the Company, the conditions described in clause (ii) of the definition of Blackout Period are met.  Such certificate shall contain an approximation of the anticipated delay.  Upon notice by the Company to the Demand Shareholders of any such determination, each Demand Shareholder covenants that it shall, subject to Applicable Law, keep the fact of any such notice strictly confidential, and, in the case of a Blackout Period pursuant to clause (ii)(y) of the definition of Blackout Period, promptly halt any offer, sale, trading or other Transfer by it or any of its Affiliates of any Registrable Securities for the duration of the Blackout Period set forth in such notice (or until such Blackout Period shall be earlier terminated in writing by the Company) and promptly halt any use, publication, dissemination or distribution of the Shelf Registration Statement, each prospectus included therein, and any amendment or supplement thereto by it and any of its Affiliates for the duration of the Blackout Period set forth in such notice (or until such Blackout Period shall be earlier terminated in writing by the Company) and, if so directed in writing by the Company, will deliver to the Company any copies then in the Demand Shareholder’s possession of the prospectus covering such Registrable Securities that was in effect at the time of receipt of such notice.

(e)                                  After the expiration of any Blackout Period and without any further request from a holder of Registrable Securities, the Company, to the extent necessary, shall as promptly as reasonably practicable prepare a post-effective amendment or supplement to the Shelf Registration Statement or the prospectus, or any document incorporated therein by reference, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, the prospectus will not include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(f)                                   At any time that a Shelf Registration Statement is effective, if any Demand Shareholder delivers a notice to the Company (a “Take-Down Notice”) stating that it intends to sell all of part of its Registrable Securities included by it on the Shelf Registration Statement (a “Shelf Offering”), then the Company shall amend or supplement the Shelf Registration Statement as may be necessary in order to enable such Registrable Securities to be distributed pursuant to the Shelf Offering (taking into account, solely in connection with a Marketed Underwritten Shelf Offering, the inclusion of Registrable Securities by any other holders pursuant to this Section 6.3).  In connection with any Shelf Offering that is an Underwritten Offering and where the plan of distribution set forth in the applicable Take-Down Notice includes a customary “road show” (including an “electronic road show”) or other substantial marketing effort by the Company and the underwriters (a “Marketed Underwritten Shelf Offering”):

(i)                                     such proposing Demand Shareholder(s) shall also deliver the Take-Down Notice to all other Demand Shareholders included on the Shelf Registration Statement and permit each such holder to include its Registrable Securities included on the Shelf Registration Statement in the Marketed Underwritten Shelf Offering if such holder notifies the proposing Demand Shareholder(s) and the Company within two (2) Business Days after delivery of the Take-Down Notice to such holder; and

(ii)                                  if the lead managing underwriter(s) advises the Company and the proposing Demand Shareholder(s) that, in its opinion, the inclusion of all of the securities sought to be sold in connection with such Marketed Underwritten Shelf Offering would materially and adversely affect the success thereof, then there shall be included in such Marketed Underwritten Shelf Offering only such securities as the proposing Demand Shareholder(s) is advised by such lead managing underwriter(s) can be sold without such adverse effect, and such number of Registrable Securities shall be allocated in the same manner as described in Section 6.1(g).  Except as otherwise expressly specified in this Section 6.3, any Marketed Underwritten Shelf Offering shall be subject to the same requirements, limitations and other provisions of this Article VI as would be applicable to a Demand Registration (i.e., as if such Marketed Underwritten Shelf Offering were a Demand Registration), including Section 6.1(e)(ii) and Section 6.1(g).

(g)                                  Notwithstanding any other provision of this Agreement, if the requesting Demand Shareholder wishes to engage in a block sale (including a block sale off of a Shelf Registration Statement or an effective automatic shelf registration statement, or in connection with the registration of the Registrable Securities under an automatic shelf registration statement for purposes of effectuating a block sale), then notwithstanding the foregoing or any other

33

provisions hereunder, no Demand Shareholder shall be entitled to receive any notice of or have its Registrable Securities included in such block sale.

(h)                                 Any time that a Shelf Offering involves a Marketed Underwritten Shelf Offering, the Requesting Shareholder(s) shall select the investment banker(s) and manager(s) that will serve as managing underwriters (including which such managing underwriters will serve as lead or co-lead) and underwriters with respect to the offering of such Registrable Securities; provided, that such investment banker(s) and manager(s) shall be reasonably acceptable to the Company (such acceptance not to be unreasonably withheld, conditioned or delayed).

6.4                               Withdrawal Rights.  Any holder of Registrable Securities having notified or directed the Company to include any or all of its Registrable Securities in a registration statement under the Securities Act shall have the right to withdraw any such notice or direction with respect to any or all of the Registrable Securities designated by it for registration by giving written notice to such effect to the Company prior to the effective date of such registration statement.  In the event of any such withdrawal, the Company shall not include such Registrable Securities in the applicable registration and such Registrable Securities shall continue to be Registrable Securities for all purposes of this Agreement (subject to the other terms and conditions of this Agreement).  No such withdrawal shall affect the obligations of the Company with respect to the Registrable Securities not so withdrawn; provided, however, that in the case of a Demand Registration, if such withdrawal shall reduce the number of Registrable Securities sought to be included in such registration below the Registrable Amount, then the Company shall as promptly as practicable give each Demand Shareholder seeking to register Registrable Securities notice to such effect and, within five (5) days following the mailing of such notice, such Demand Shareholder still seeking registration shall, by written notice to the Company, elect to register additional Registrable Securities to satisfy the Registrable Amount or elect that such registration statement not be filed or, if theretofore filed, be withdrawn.  During such five (5) day period, the Company shall not file such registration statement if not theretofore filed or, if such registration statement has been theretofore filed, the Company shall not seek, and shall use commercially reasonable efforts to prevent, the effectiveness thereof.

6.5                               Hedging Transactions

(a)                                 The provisions of this Agreement relating to the registration, offer and sale of Registrable Securities shall apply also to (i) any transaction which Transfers some or all of the economic risk of ownership of Registrable Securities, including any forward contract, equity swap, put or call, put or call equivalent position, collar, margin loan, sale of exchangeable security or similar transaction (including the registration, offer and sale under the Securities Act of Registrable Securities pledged to the counterparty to such transaction or of securities of the same class as the underlying Registrable Securities by the counterparty to such transaction in connection therewith), and that the counterparty to such transaction shall be selected in the sole discretion of the Demand Shareholders and (ii) any derivative transactions in which a broker-dealer, other financial institution or unaffiliated Person (each, a “Hedging Counterparty”) may sell Registrable Securities covered by any prospectus and the applicable prospectus supplement including short sale transactions using Registrable Securities pledged by a Demand Shareholder or borrowed from the Demand Shareholder or others and Registrable Securities loaned, pledged

34

or hypothecated to any such party (each, a “Hedging Transaction”); provided that the Demand Shareholder’s legal counsel has determined in its reasonable judgment (after good-faith consultation with counsel of the Company) that it is reasonably necessary to register under the Securities Act such Hedging Transaction.  Any written information regarding the Hedging Transaction provided to the Company by a Hedging Counterparty for inclusion in any registration statement, prospectus or free writing prospectus filed pursuant to this Section 6.5 shall, for purposes of Section 6.9, be deemed to be written information provided by a Selling Shareholder for purposes of Section 6.9.

(b)                                 If in connection with a Hedging Transaction, a Hedging Counterparty or any Affiliate thereof is (or may reasonably be considered) an underwriter or selling stockholder, then such Hedging Counterparty shall be required to provide customary indemnities to the Company regarding the plan of distribution and related matters.

6.6                               Holdback Agreements.

(a)                         Walmart shall enter into customary agreements restricting the sale or distribution of Equity Securities of the Company (including sales pursuant to Rule 144 under the Securities Act) to the extent required by the lead managing underwriter(s) with respect to an applicable Underwritten Offering in which Walmart participates during the period commencing on the date of the request (which shall be no earlier than fourteen (14) days prior to the expected “pricing” of such Underwritten Offering) and continuing for not more than ninety (90) days after the date of the “final” prospectus (or “final” prospectus supplement if the Underwritten Offering is made pursuant to a Shelf Registration Statement), pursuant to which such Underwritten Offering shall be made.  The Company shall not include Registrable Securities of any other Demand Shareholder in such an Underwritten Offering unless such other Demand Shareholder enters into a customary agreement restricting the sale or distribution of Equity Securities of the Company (including sales pursuant to Rule 144 under the Securities Act) if requested by the lead managing underwriter(s).

(b)                                 If any Demand Registration or Shelf Offering involves an Underwritten Offering, the Company will not affect any sale or distribution of shares of Common Stock (or securities convertible into or exchangeable or exercisable for shares of Common Stock) (other than a registration statement on Form S-4, Form S-8 or any successor forms thereto) for its own account, within sixty (60) days (plus an extension period as may be proposed by the lead managing underwriter(s) for such Underwritten Offering to address FINRA regulations regarding the publication of research, or such shorter periods as the lead managing underwriter(s) may agree with the Company), after the effective date of such registration except as may otherwise be agreed between the Company and the lead managing underwriter(s) of such Underwritten Offering.

6.7                               Registration Procedures.

(a)                                 If and whenever the Company is required to use commercially reasonable efforts to effect the registration of any Registrable Securities under the Securities Act as provided

35

in Section 6.1, Section 6.2 or Section 6.3, the Company shall as expeditiously as reasonably practicable:

(i)                                     prepare and file with the Commission a registration statement to effect such registration in accordance with the intended method or methods of distribution of such securities and thereafter use commercially reasonable efforts to cause such registration statement to become and remain effective pursuant to the terms of this Article VI; provided, however, that the Company may discontinue any registration of its securities which are not Registrable Securities at any time prior to the effective date of the registration statement relating thereto; provided, further, that before filing such registration statement or any amendments thereto, the Company will furnish to the Demand Shareholders which are including Registrable Securities in such registration (“Selling Shareholders”), their counsel and the lead managing underwriter(s), if any, copies of all such documents proposed to be filed, which documents will be subject to the review and reasonable comment of such counsel, and other documents reasonably requested by such counsel, including any comment letter from the Commission, and, if requested by such counsel, provide such counsel reasonable opportunity to participate in the preparation of such registration statement and each prospectus included therein and such other opportunities to conduct a reasonable investigation within the meaning of the Securities Act, including reasonable access to the Company’s books and records, officers, accountants and other advisors.  The Company shall not file any such registration statement or prospectus or any amendments or supplements thereto with respect to a Demand Registration to which the holders of a majority of Registrable Securities held by the Requesting Shareholder(s), their counsel or the lead managing underwriter(s), if any, shall reasonably object, in writing, on a timely basis, unless, in the opinion of the Company, such filing is necessary to comply with Applicable Law;

(ii)                                  except in the case of a Shelf Registration Statement, prepare and file with the Commission such amendments, including post-effective amendments, and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective pursuant to the terms of this Article VI, and comply in all material respects with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement;

(v)                                 furnish to the Selling Shareholders and each underwriter, if any, of the securities being sold by such Selling Shareholders such number of conformed copies of such registration statement and of each amendment and supplement thereto, such number of copies of the prospectus contained in such registration statement (including each preliminary prospectus and any summary prospectus) and each free writing prospectus (as defined in Rule 405 of the Securities Act) (a “Free Writing Prospectus”) utilized in connection therewith and any other prospectus filed under Rule 424 under the Securities Act, in conformity with the requirements of the Securities Act, and such other documents as such Selling Shareholders and underwriter, if any, may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities owned by such Selling Shareholders;

(b)           The Company shall not grant to any Person any demand, piggyback or shelf registration rights the terms of which are senior to or conflict with the rights granted to Walmart hereunder without the prior written consent of Walmart.  If Walmart provides such consent, Walmart and the Company shall amend this Agreement to grant Walmart any such senior demand, piggyback or shelf registration rights.

(d)           In any case in which any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and, to the extent that it may wish, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and acknowledging the obligations of the indemnifying party with respect to such proceeding, the indemnifying party will not (so long as it shall continue to have the right to defend, contest, litigate and settle the matter in question in accordance with this paragraph) be liable to such indemnified party hereunder for any legal or other expense subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation, supervision and monitoring (unless (i) such indemnified party reasonably objects to such assumption on the grounds that (A) there may be defenses available to it which are different from or in addition to the defenses available to such indemnifying party or (B) such action involves, or is reasonably likely to have an effect beyond, the scope of matters that are subject to indemnification pursuant to this Section 6.10, or (ii) the indemnifying party shall have failed within a reasonable period of time to assume such defense and the indemnified party is or would reasonably be expected to be materially prejudiced by such delay, in either event the indemnified party shall be promptly reimbursed by the indemnifying party for the expenses incurred in connection with retaining one separate legal counsel (for the avoidance of doubt, for all indemnified parties in connection therewith)).  For the avoidance of doubt, notwithstanding any such assumption by an indemnifying party, the indemnified party shall have the right to employ separate counsel in any such matter and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party except as provided in the previous sentence.  An indemnifying party shall not be liable for any settlement of an action or claim effected without its consent.  No matter shall be settled by an indemnifying party without the consent of the indemnified party (which consent shall not be unreasonably withheld, conditioned or delayed), unless such settlement (x) includes as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation, (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any indemnified party and (z) is settled solely for cash for which the indemnified party would be entitled to indemnification hereunder.

(e)           The indemnification provided for under this Agreement shall survive the Transfer of the Registrable Securities and the termination of this Agreement.

(f)            If recovery is not available under the foregoing indemnification provisions for any reason or reasons other than as specified therein, any Person who would otherwise be entitled to indemnification by the terms thereof shall nevertheless be entitled to contribution with respect to any Losses with respect to which such Person would be entitled to such indemnification but for such reason or reasons, in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and such indemnified party, on the other hand, in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations.  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

44

party, the Persons’ relative knowledge and access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission, and other equitable considerations appropriate under the circumstances.  It is hereby agreed that it would not necessarily be equitable if the amount of such contribution were determined by pro rata or per capita allocation.  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 was not found guilty of such fraudulent misrepresentation.  Notwithstanding the foregoing, no Selling Shareholder shall be required to make a contribution in excess of the amount received by such Selling Shareholder from its sale of Registrable Securities in connection with the offering that gave rise to the contribution obligation.

6.11        Free Writing Prospectuses.  Walmart shall not use any “free writing prospectus” (as defined in Rule 405 under the Securities Act) in connection with the sale of Registrable Securities pursuant to this Article VI without the prior written consent of the Company (which consent shall not be unreasonably withheld, conditioned or delayed).  Notwithstanding the foregoing, Walmart may use any free writing prospectus prepared and distributed by the Company.

6.12        Termination of Registration Rights.  The rights granted pursuant to this Article VI shall terminate, as to any holder of Registrable Securities on the date the Company is acquired in a transaction approved by the Company’s Board (including, without limitation, through a merger, consolidation, stock purchase, or sale of all or substantially all of the Company’s assets) or the earlier to occur of (a) the date on which all Registrable Securities held by such holder have been disposed; (b) the date on which all Registrable Securities held by such holder may be sold without registration in compliance with Rule 144 without regard to volume limitations or other restrictions on transfer thereunder.

(iii)                               Notwithstanding the foregoing, if at any time during the Exercise Period the Warrantholder has not exercised this Warrant in full as a result of there being insufficient Warrant Shares available for issuance or the lack of any required regulatory, corporate or other approval (including, for the avoidance of doubt, the Initial Antitrust Clearance and Requisite Stockholder Approval (each, as defined in the Transaction Agreement)), the Expiration Time shall be extended until sixty (60) days after such date as the Warrantholder is able to acquire all of the vested Warrant Shares without violating Applicable Law.

8

to the Warrantholder as of the close of business on the date on which this Warrant and payment of the Exercise Price are delivered to the Company in accordance with the terms of this Warrant, notwithstanding that the stock transfer books of the Company may then be closed or certificates representing such Equity Interests may not be actually delivered on such date.  The Company shall use reasonable best efforts to obtain the Requisite Stockholder Approval (as defined in the Transaction Agreement) if required, and shall at all times reserve and keep available, out of its authorized but unissued Equity Interests, solely for the purpose of providing for the exercise of this Warrant, the aggregate Equity Interests issuable upon exercise of this Warrant in full (disregarding whether or not this Warrant is exercisable by its terms at any such time).  The Company shall, at its sole expense, procure, subject to issuance or notice of issuance, the listing of any Equity Interests issuable upon exercise of this Warrant on the principal stock exchange on which such Equity Interests are then listed or traded, promptly after such Equity Interests are eligible for listing thereon.

5.                                      No Fractional Shares or Scrip.  No fractional Warrant Shares or other Equity Interests or scrip representing fractional Warrant Shares or other Equity Interests shall be issued upon any exercise of this Warrant.  In lieu of any fractional share to which a Warrantholder would otherwise be entitled, the fractional Warrant Shares or other Equity Interests shall be rounded up to the next whole Warrant Share or other Equity Interest and the Warrantholder shall be entitled to receive such rounded up number of Warrant Shares or other Equity Interests.

6.                                      No Rights as Stockholders; Transfer Books.  Without limiting in any respect the provisions of the Transaction Agreement and except as otherwise provided by the terms of this Warrant, this Warrant does not entitle the Warrantholder to (i) receive dividends or other distributions, (ii) consent to any action of the stockholders of the Company, (iii) receive notice of or vote at any meeting of the stockholders, (iv) receive notice of any other proceedings of the Company, or (v) exercise any other rights whatsoever, in any such case, as a stockholder of the Company prior to the date of exercise hereof.

8.                                      Transfer/Assignment.

(i)                                     This Warrant may be transferred only to an Affiliate of Walmart.  The Warrant Shares may be transferred only in accordance with the terms of the Transaction Agreement.  Subject to compliance with the first two sentences of this Section 8, the legend as set forth on the cover page of this Warrant and the terms of the Transaction Agreement, this Warrant and all rights hereunder are transferable, in whole or in part, upon the books of the Company by the registered holder hereof in person or by duly authorized attorney, and a new Warrant shall be made and delivered by the Company, of the same tenor and date as this Warrant but registered in the name of one or more transferees, upon surrender of this Warrant, duly endorsed, to the office or agency of the Company described in Section 3.  If the transferring

9

holder does not transfer the entirety of its rights to purchase all Warrant Shares hereunder, such holder shall be entitled to receive from the Company a new Warrant in substantially identical form for the purchase of that number of Warrant Shares as to which the right to purchase was not transferred.  All expenses (other than stock transfer taxes) and other charges payable in connection with the preparation, execution and delivery of the new Warrant pursuant to this Section 8 shall be paid by the Warrantholder.

(ii)                                  If and for so long as required by the Transaction Agreement, this Warrant Certificate shall contain a legend as set forth in Section 4.2 of the Transaction Agreement.

9.                                      Exchange and Registry of Warrant.  This Warrant is exchangeable, subject to applicable securities laws, upon the surrender hereof by the Warrantholder to the Company, for a new warrant or warrants of like tenor and representing the right to purchase the same aggregate number of Warrant Shares.  The Company shall maintain a registry showing the name and address of the Warrantholder as the registered holder of this Warrant.  This Warrant may be surrendered for exchange or exercise, in accordance with its terms, at the office of the Company, and the Company shall be entitled to rely in all respects, prior to written notice to the contrary, upon such registry.

10.                               Loss, Theft, Destruction or Mutilation of Warrant.  Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant, and in the case of any such loss, theft or destruction, upon receipt of a bond, indemnity or security reasonably satisfactory to the Company, or, in the case of any such mutilation, upon surrender and cancellation of this Warrant, the Company shall make and deliver, in lieu of such lost, stolen, destroyed or mutilated Warrant, a new Warrant of like tenor and representing the right to purchase the same aggregate number of Warrant Shares as provided for in such lost, stolen, destroyed or mutilated Warrant.

11.                               Saturdays, Sundays, Holidays, etc.  If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding day that is a Business Day.

12.                               Adjustments and Other Rights.  The Exercise Price and Warrant Shares issuable upon exercise of this Warrant shall be subject to adjustment from time to time as follows; provided that if more than one subsection of this Section 12 is applicable to a single event, the subsection shall be applied that produces the largest adjustment and no single event shall cause an adjustment under more than one subsection of this Section 12 so as to result in duplication.

(i)                                     Stock Splits, Subdivisions, Reclassifications or Combinations.  If the Company shall at any time or from time to time (a) declare, order, pay or make a dividend or make a distribution on Common Stock in additional shares of Common Stock, (b) split, subdivide or reclassify the outstanding shares of Common Stock into a greater number of shares or (c) combine or reclassify the outstanding shares of Common Stock into a smaller number of shares, the number of Warrant Shares issuable upon exercise of this Warrant at the time of the record date for such dividend or distribution or the effective date of such split, subdivision, combination or reclassification shall be proportionately adjusted so that the Warrantholder

10

immediately after such record date or effective date, as the case may be, shall be entitled to purchase the number of shares of Common Stock which such holder would have owned or been entitled to receive in respect of the shares of Common Stock subject to this Warrant after such date had this Warrant been exercised in full immediately prior to such record date or effective date, as the case may be (disregarding whether or not this Warrant had been exercisable by its terms at such time).  In the event of such adjustment, the Exercise Price in effect at the time of the record date for such dividend or distribution or the effective date of such split, subdivision, combination or reclassification shall be immediately adjusted to the number obtained by dividing (x) the product of (1) the number of Warrant Shares issuable upon the exercise of this Warrant in full before the adjustment determined pursuant to the immediately preceding sentence (disregarding whether or not this Warrant was exercisable by its terms at such time) and (2) the Exercise Price in effect immediately prior to the record or effective date, as the case may be, for the dividend, distribution, split, subdivision, combination or reclassification giving rise to such adjustment by (y) the new number of Warrant Shares issuable upon exercise of the Warrant in full determined pursuant to the immediately preceding sentence (disregarding whether or not this Warrant is exercisable by its terms at such time); provided that such product shall be rounded to the nearest whole Warrant Share.

(ii)           Certain Issuances of Common Stock or Convertible Securities.  If the Company shall at any time or from time to time issue shares of Common Stock (or rights or warrants or any other securities or rights exercisable or convertible into or exchangeable for shares of Common Stock (collectively, a “conversion”)), including through distributions on outstanding securities (collectively, “Convertible Securities”) (other than in Permitted Transactions or transactions to which the adjustments set forth in Section 12(i) are applicable), without consideration or at a consideration per share (or having a conversion price per share) that is less than the highest then applicable Exercise Price (the date of such issuance, the “Pricing Date”) then, in such event:

(A)          the number of Warrant Shares issuable upon the exercise of this Warrant immediately prior to the Pricing Date (the “Initial Number”) shall be increased to the number obtained by multiplying the Initial Number by a fraction (I) the numerator of which shall be the sum of (x) the number of shares of Common Stock outstanding immediately prior to the Pricing Date and (y) the number of additional shares of Common Stock issued (or into which Convertible Securities may be converted) and (II) the denominator of which shall be the sum of (x) the number of shares of Common Stock outstanding immediately prior to the Pricing Date and (y) the number of shares of Common Stock (rounded to the nearest whole share) which the Aggregate Consideration in respect of such issuance of shares of Common Stock (or Convertible Securities) would purchase at the Market Price of Common Stock immediately prior to the Pricing Date; and

(B)          the Exercise Price payable upon exercise of this Warrant shall be adjusted by multiplying such Exercise Price in effect immediately prior to the Pricing Date by a fraction, the numerator of which shall be the number of shares of Common Stock issuable upon exercise of this Warrant in full immediately prior to the adjustment pursuant to clause (A) above (disregarding whether or not this Warrant was exercisable by its terms at such time), and the denominator of which shall be the number of shares of Common Stock issuable upon exercise of this Warrant in full immediately after the adjustment pursuant to clause (A) above

11

(disregarding whether or not this Warrant is exercisable by its terms at such time).

For purposes of the foregoing, (1) the “Aggregate Consideration” in respect of such issuance of shares of Common Stock (or Convertible Securities) shall be deemed to be equal to the sum of the gross offering price (before deduction of any related expenses payable to third parties, including discounts and commissions) of all such shares of Common Stock and Convertible Securities, plus the aggregate amount, if any, payable upon conversion of any such Convertible Securities (assuming conversion in accordance with their terms immediately following their issuance (and further assuming for this purpose that such Convertible Securities are convertible at such time)); (2) in the case of the issuance of such shares of Common Stock or Convertible Securities for, in whole or in part, any non-cash property (or in the case of any non-cash property payable upon conversion of any such Convertible Securities), the consideration represented by such noncash property shall be deemed to be the Market Price (in the case of securities) and/or Fair Market Value (in all other cases), as applicable, of such non-cash property as of immediately prior to the Pricing Date (before deduction of any related expenses payable to third parties, including discounts and commissions); (3) if the Exercise Price and the number of Warrant Shares issuable upon exercise of this Warrant shall have been adjusted upon the issuance of any Convertible Securities in accordance with this Section 12, no further adjustment of the Exercise Price and the number of Warrant Shares issuable upon exercise of this Warrant shall be made for the actual issuance of shares of Common Stock upon the actual conversion of such Convertible Securities in accordance with their terms; and (4) “Permitted Transactions” shall include (a) issuances of shares of Common Stock (including upon exercise of options) to directors, advisors, employees or consultants of the Company pursuant to a stock option plan, employee stock purchase plan, restricted stock plan, other employee benefit plan or other similar compensatory agreement or arrangement approved by the Board of Directors, (b) the issuance of Historical Warrant Shares, (c) any sale of the Company’s Equity Interests pursuant to a registered public offering, (d) sales of Common Stock in transactions deemed to be “at-the-market” sales pursuant to Rule 415 of the Securities Act, (e) issuances of Common Stock as matching contributions under the Company’s 401(k) plan, (f) the issuance of securities as payment in satisfaction of accrued dividends payable upon the Series C Stock, (g) issuances of Common Stock upon conversion of the Series C Stock and (h) the Common Stock issuable upon exercise of this Warrant.  For the avoidance of doubt, except in connection with any transaction described in Section 12(i), no adjustment pursuant to this Section 12(ii) shall be made to an applicable Exercise Price or number of related Warrant Shares in the case of the issuance of Common Stock or Convertible Securities at a consideration per share (or having a conversion or exercise price per share) that is equal to or greater than such Exercise Price. Any adjustment made pursuant to this Section 12(ii) shall become effective immediately upon the date of such issuance.  For the avoidance of doubt, no increase to the Exercise Price or decrease in the number of Warrant Shares issuable upon exercise of this Warrant shall be made pursuant to this Section 12(ii).

(iii)          Distributions.  If the Company, at any time while this Warrant is outstanding, declares or makes any dividend or distributes to holders of shares of Common Stock (and not to the Warrantholder) evidences of its indebtedness or assets (including cash and cash dividends or property) or rights or warrants to subscribe for or purchase any security (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other

12

similar transaction other than dividends or distributions pursuant to Section 12(i)) (a “Distribution”), then the Warrantholder will be entitled to participate in such Distribution to the same extent that the Warrantholder would have participated therein if the Warrantholder had held the number of shares of Common Stock acquirable upon exercise of the Warrant solely to the extent exercisable immediately before the date as of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution;  provided, however, payments of dividends, whether in cash or Common Stock, on the Series C Stock in accordance with the terms of the Certificate of Designations of the Series C Stock, shall not be a “Distribution” for purposes of this Section 12(iii).

(iv)          Repurchases.  If the Company shall at any time or from time to time effect Repurchases (other than a Permitted Repurchase), then the Exercise Price shall be reduced to the price determined by multiplying the Exercise Price in effect immediately prior to the first purchase of Equity Interests comprising such Repurchases by a fraction of which the numerator shall be (A) the product of (1) the number of shares of Common Stock outstanding immediately prior to the first purchase of Equity Interests comprising such Repurchases and (2) the Market Price per share of Common Stock on the Trading Day immediately preceding the first public announcement by the Company of the intent to effect such Repurchases, minus (B) the Assumed Payment Amount, and of which the denominator shall be the product of (X) the number of shares of Common Stock outstanding immediately prior to the first purchase of Equity Interests comprising such Repurchases minus the number of shares of Common Stock so repurchased and (Y) the Market Price per share of Common Stock on the Trading Day immediately preceding the first public announcement by the Company of the intent to effect such Repurchases.  In such event, the number of Warrant Shares issuable upon the exercise of this Warrant shall be increased to the number obtained by multiplying such number of Warrant Shares by the quotient of (A) the Exercise Price in effect immediately prior to the first purchase of Equity Interests comprising such Repurchases divided by (B) the new Exercise Price determined in accordance with the immediately preceding sentence.  For the avoidance of doubt, no increase to the Exercise Price or decrease in the number of Warrant Shares issuable upon exercise of this Warrant shall be made pursuant to this Section 12(iv).  For purposes of the foregoing, the “Assumed Payment Amount” with respect to any Repurchases shall mean the aggregate Market Price (in the case of securities) and/or Fair Market Value (in the case of cash and/or any other property), as applicable, as of such Repurchases, of the aggregate consideration paid to effect such Repurchases.

(v)           Change of Control Transactions. In case of any Change of Control Transaction or reclassification of Common Stock (other than a reclassification of Common Stock subject to adjustment pursuant to Section 12(i)), notwithstanding anything to the contrary contained herein, (a) the Company shall notify the Warrantholder in writing of such Change of Control Transaction or reclassification as promptly as practicable (but in no event later than 10 Business Days prior to the effectiveness thereof), (b) if (A) Warrant Shares representing less than 60% of the aggregate Warrant Shares as of the Change of Control Transaction (the “Acceleration Limit”) have vested as of such Change of Control Transaction or reclassification of Common Stock (the difference between the number of vested Warrant Shares immediately prior to such Change of Control Transaction or reclassification of Common Stock and the Acceleration Limit, the “Accelerated Shares”); and (B) either (1) no fewer than fifteen (15) sites

13

shall have been installed pursuant to the Power Purchase Agreement prior to the two year anniversary of the date of signing of this Warrant; or (2) the Change of Control occurs prior to such two year anniversary, then a number of unvested Warrant Shares equal to the Accelerated Shares shall immediately vest fully and become non-forfeitable and, subject to clause (c) below, become immediately exercisable upon consummation of such Change of Control Transaction or reclassification and (c) solely in the event of a Change of Control Transaction that is a Business Combination or a reclassification, the Warrantholder’s right to receive Warrant Shares upon exercise of this Warrant shall be converted, effective upon the occurrence of such Business Combination or reclassification, into the right to exercise this Warrant to acquire the number of shares of stock or other securities or property (including cash) that the shares of Common Stock issuable (at the time of such Business Combination or reclassification) upon exercise of this Warrant immediately prior to such Business Combination or reclassification would have been entitled to receive upon consummation of such Business Combination or reclassification.  In determining the kind and amount of stock, securities or the property receivable upon exercise of this Warrant upon and following adjustment pursuant to this paragraph, if the holders of Common Stock have the right to elect the kind or amount of consideration receivable upon consummation of such Business Combination (an “Election Mechanic”), then the Warrantholder shall have the right to make the same election upon exercise of this Warrant with respect to the number of shares of stock or other securities or property which the Warrantholder shall receive upon exercise of this Warrant.  The Company, or the Person or Persons formed by the applicable Business Combination or reclassification, or that acquire(s) the applicable shares of Common Stock, as the case may be, shall make lawful provisions to establish such rights and to provide for such adjustments that, for events from and after such Business Combination or reclassification, shall be as nearly equivalent as possible to the rights and adjustments provided for herein, and the Company shall not be a party to or permit any such Business Combination or reclassification to occur unless such provisions are made as a part of the terms thereof.

(vi)          Rounding of Calculations; Minimum Adjustments.  All calculations under this Section 12 shall be made to the nearest one-tenth (1/10th) of a cent or to the nearest one-hundredth (1/100th) of a share, as the case may be.  Any provision of this Section 12 to the contrary notwithstanding, no adjustment in the Exercise Price or the number of Warrant Shares into which this Warrant is exercisable shall be made if the amount of such adjustment would be less than $0.01 or one-tenth (1/10th) of a share of Common Stock, but any such amount shall be carried forward and an adjustment with respect thereto shall be made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate $0.01 or 1/10th of a share of Common Stock, or more.

(vii)         Timing of Issuance of Additional Securities Upon Certain Adjustments.  In any case in which (a) the provisions of this Section 12 shall require that an adjustment (the “Subject Adjustment”) shall become effective immediately after a record date (the “Subject Record Date”) for an event and (b) the Warrantholder exercises this Warrant after the Subject Record Date and before the consummation of such event, the Company may defer until the consummation of such event issuing to such Warrantholder the incrementally additional shares of Common Stock or other property issuable upon such exercise by reason of the Subject Adjustment;  provided, however, that the Company upon request shall promptly deliver to such Warrantholder a due bill or other appropriate instrument evidencing such Warrantholder’s right

14

to receive such additional shares (or other property, as applicable), upon the consummation of such event.

(viii)        Statement Regarding Adjustments.  Whenever the Exercise Price or the Warrant Shares into which this Warrant is exercisable shall be adjusted as provided in Section 12, the Company shall promptly prepare a statement showing in reasonable detail the facts requiring such adjustment and the Exercise Price that shall be in effect and the Warrant Shares into which this Warrant shall be exercisable after such adjustment, and cause a copy of such statement to be delivered to the Warrantholder as promptly as practicable after the event giving rise to the adjustment.

(ix)          Notice of Adjustment Event.  In the event that the Company shall propose to take any action of the type described in this Section 12 (but only if the action of the type described in this Section 12 would result in an adjustment in the Exercise Price or the Warrant Shares into which this Warrant is exercisable or a change in the type of securities or property to be delivered upon exercise of this Warrant), the Company shall provide written notice to the Warrantholder, which notice shall specify the record date, if any, with respect to any such action and the approximate date on which such action is to take place.  Such notice shall also set forth the facts with respect thereto as shall be reasonably necessary to indicate the effect on the Exercise Price and the number, kind or class of shares or other securities or property which shall be deliverable upon exercise of this Warrant.  In the case of any action which would require the fixing of a record date, such notice shall be given at least 10 days prior to the date so fixed.  In case of all other action, such notice shall be given at least 10 days prior to the taking of such proposed action unless the Company reasonably determines in good faith that, given the nature of such action, the provision of such notice at least 10 days in advance is not reasonably practicable from a timing perspective, in which case such notice shall be given as far in advance prior to the taking of such proposed action as is reasonably practicable from a timing perspective.

(x)           Adjustment Rules.  Any adjustments pursuant to this Section 12 shall be made successively whenever an event referred to herein shall occur.  If an adjustment in Exercise Price made hereunder would reduce the Exercise Price to an amount below par value of the Common Stock, then such adjustment in Exercise Price made hereunder shall reduce the Exercise Price to the par value of the Common Stock.

(xi)          No Impairment.  The Company shall not, by amendment of its certificate of incorporation, bylaws or any other organizational document, or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but shall at all times in good faith assist in the carrying out of all the provisions of this Warrant.  In furtherance and not in limitation of the foregoing, the Company shall not take or permit to be taken any action which would (A) increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect or (B) entitle the Warrantholder to an adjustment under this Section 12 if the total number of shares of Common Stock issuable after such action upon exercise of this Warrant in full (disregarding whether or not this Warrant is exercisable by its terms at such time), together with all shares of Common Stock then outstanding and all shares of Common Stock then issuable upon the exercise in full of any and all outstanding Equity Interests

15

(disregarding whether or not any such Equity Interests are exercisable by their terms at such time) would exceed the total number of shares of Common Stock then authorized by its certificate of incorporation.

(xii)         Proceedings Prior to Any Action Requiring Adjustment.  As a condition precedent to the taking of any action which would require an adjustment pursuant to this Section 12, the Company shall take any and all action which may be necessary, including obtaining regulatory or other governmental, NASDAQ or other applicable securities exchange, corporate or stockholder approvals or exemptions, in order that the Company may thereafter validly and legally issue as fully paid and nonassessable all shares of Common Stock, or all other securities or other property, that the Warrantholder is entitled to receive upon exercise of this Warrant pursuant to this Section 12.

13.          Beneficial Ownership Limitation.

(i)            Notwithstanding anything in this Warrant to the contrary, the Company shall not honor any exercise of this Warrant, and a Warrantholder shall not have the right to exercise any portion of this Warrant, to the extent that, after giving effect to an attempted exercise set forth on an applicable Notice of Exercise, such Warrantholder (together with such Warrantholder’s Affiliates, and any other Person whose beneficial ownership of Common Stock would be aggregated with the Warrantholder’s for purposes of Section 13(d) or Section 16 of the Exchange Act, and any other applicable regulations of the U.S. Securities and Exchange Commission (the “Commission”), including any “group” of which the Warrantholder is a member (the foregoing, “Attribution Parties”)) would beneficially own a number of shares of Common Stock in excess of the Beneficial Ownership Limitation.  For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by such Warrantholder and its Attribution Parties shall include the number of Warrant Shares issuable under the Notice of Exercise with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (a) exercise of the remaining, unexercised portion of any Warrant beneficially owned by such Warrantholder or any of its Attribution Parties, and (b) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company (including any warrants) beneficially owned by such Warrantholder or any of its Attribution Parties that are subject to a limitation on conversion or exercise similar to the limitation contained herein.  For purposes of this Section 13, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and any other applicable regulations of the Commission.  In addition, for purposes hereof, “group” has the meaning set forth in Section 13(d) of the Exchange Act and the applicable regulations of the Commission.  For purposes of this Section 13, in determining the number of outstanding shares of Common Stock, a Warrantholder may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following:  (x) the Company’s most recent periodic or annual filing with the Commission, as the case may be, (y) a more recent public announcement by the Company that is filed with the Commission, or (z) a more recent notice by the Company or the Company’s transfer agent to the Warrantholder setting forth the number of shares of Common Stock then outstanding.  Upon the written request of a Warrantholder (which may be by email), the Company shall, within three (3) Trading Days thereof, confirm in writing to such Warrantholder (which may be via email) the number of shares of Common Stock then outstanding.  In any case, the number of outstanding shares of Common Stock shall be

16

determined after giving effect to any actual conversion or exercise of securities of the Company, including exercise of this Warrant, by such Warrantholder or its Attribution Parties since the date as of which such number of outstanding shares of Common Stock was last publicly reported or confirmed to the Warrantholder.  The Company shall be entitled to rely on representations made to it by the Warrantholder in any Notice of Exercise regarding its Beneficial Ownership Limitation.  The Warrantholder acknowledges that the Warrantholder is solely responsible for any schedules or statements required to be filed by it in accordance with Section 13(d) or Section 16(a) of the Exchange Act.

(ii)           The “Beneficial Ownership Limitation” shall initially be 4.999% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock pursuant to such Notice of Exercise (to the extent permitted pursuant to this Section 13); provided, however, that by written notice to the Company, which will not be effective until the 61st day after such notice is given by the Warrantholder to the Company, the Warrantholder may waive or amend the provisions of this Section 13 to change the Beneficial Ownership Limitation to any other number, and the provisions of this Section 13 shall continue to apply.  Upon any such waiver or amendment to the Beneficial Ownership Limitation, the Beneficial Ownership Limitation may not be further waived or amended by the Warrantholder without first providing the minimum written notice required by the immediately preceding sentence.  Notwithstanding the foregoing, at any time following notice of a Change of Control Transaction under Section 12(v) with respect to a Change of Control Transaction that is pursuant to any tender offer or exchange offer (by the Company or another Person (other than the Warrantholder or any Affiliate of the Warrantholder)), the Warrantholder may waive or amend the Beneficial Ownership Limitation effective immediately upon written notice to the Company and may reinstitute a Beneficial Ownership Limitation at any time thereafter effective immediately upon written notice to the Company.

(iii)          Notwithstanding the provisions of this Section 13, none of the provisions of this Section 13 shall restrict in any way the number of shares of Common Stock which the Warrantholder may receive or beneficially own in order to determine the amount of securities or other consideration that the Warrantholder may receive in the event of a Change of Control Transaction as contemplated in Section 12 of this Warrant.

14.          Governing Law and Jurisdiction.  This Warrant shall be governed by, and construed and enforced in accordance with, the laws of the State of New York, without regard to any choice or conflict of law provision or rule (whether of the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of New York.  In addition, each of the parties (a) submits to the personal jurisdiction and venue of the United States District Court for the Southern District of New York or any New York State court sitting in the Borough of Manhattan, City of New York and appellate courts having jurisdiction of appeals from any of the foregoing (the “Chosen Courts”), in the event any dispute (whether in contract, tort or otherwise) arises out of this Warrant or the transactions contemplated hereby, (b) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, and (c) agrees that it shall not bring any claim, action or proceeding relating to this Warrant or the transactions contemplated hereby in any court other than the Chosen Courts.  Each party agrees that service of process upon

17

such party in any such claim, action or proceeding shall be effective if notice is given in accordance with the provisions of this Warrant.

15.          Binding Effect.  This Warrant shall be binding upon any successors or assigns of the Company.

16.          Amendments.  This Warrant may be amended and the observance of any term of this Warrant may be waived only with the written consent of the Company and the Warrantholder.

17.          Notices.  Any notice, request, instruction or other document to be given hereunder by any party to the other shall be in writing and shall be deemed to have been duly given (a) if sent by registered or certified mail in the United States return receipt requested, upon receipt, (b) if sent by nationally recognized overnight air courier, one Business Day after mailing, (c) if sent by email or facsimile, with a copy mailed on the same day in the manner provided in clauses (a) or (b) of this Section 17 when transmitted and receipt is confirmed, or (d) if otherwise personally delivered, when delivered.  All notices hereunder shall be delivered as set forth below, or pursuant to such other instructions as may be designated in writing by the party to receive such notice.

18

18.          Entire Agreement.  This Warrant and the form attached hereto, the Transaction Agreement, the other Transaction Documents, and the Power Purchase Agreement constitute the entire agreement, and supersede all other prior agreements, understandings, representations and warranties, both written and oral, between the parties, with respect to the subject matter hereof.

19.          Specific Performance.  The parties agree that failure of any party to perform its agreements and covenants hereunder, including a party’s failure to take all actions as are necessary on such party’s part in accordance with the terms and conditions of this Warrant to consummate the transactions contemplated hereby, will cause irreparable injury to the other party, for which monetary damages, even if available, will not be an adequate remedy.  It is agreed that the parties shall be entitled to equitable relief including injunctive relief and specific performance of the terms hereof, without the requirement of posting a bond or other security, and each party hereby consents to the issuance of injunctive relief by any court of competent jurisdiction to compel performance of a party’s obligations and to the granting by any court of the remedy of specific performance of such party’s obligations hereunder, this being in addition to any other remedies to which the parties are entitled at law or equity.

20.          Limitation of Liability.  No provision hereof, in the absence of any affirmative action by the Warrantholder to exercise this Warrant to purchase Warrant Shares, and no enumeration herein of the rights or privileges of Warrantholder, shall give rise to any liability of the Warrantholder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.
