ARTICLE 2.
REGISTRATION OF STOCK

     2.1 Demand Registration.

     (a) Request for Registration.

     (i) From and after the earlier of (i) 180 days following a Qualified Public Offering or (ii) the effective date of a shelf registration statement with respect to the resale of shares of Common Stock sold pursuant to a private offering of Common Stock, any (a) Sponsor Demand Holder, assuming such Sponsor Demand Holder holds in the aggregate at least 5% of the Company’s Fully-Diluted Common Stock, or (b) any Non-Sponsor Demand Holder, assuming all Non-Sponsor Demand Holders collectively hold in the aggregate at least 5% of the Company’s Fully-Diluted Common Stock, may make a written request of the Company (a “Demand Request”) to have the Company effect a registration under the Securities Act (a “Demand Registration”) for the sale of all or part of their Registrable Securities. Following receipt of such Demand Request, the Company shall be required to use commercially reasonable efforts to effect such Demand Registration subject to the terms hereof; provided that the Registrable Securities proposed to be offered by the Requesting Holders in any such Demand Request must have a reasonably anticipated aggregate offering price of at least $20,000,000 net of underwriting discounts and commissions; and provided further that (x) each of StepStone/Citi and Energy Spectrum shall be entitled to make no more than three Demand Requests pursuant to the foregoing provisions and (y) subject to paragraph (b) below, the Non-Sponsor Demand Holders (regardless of whether certain Non-Sponsor

Demand Holders do not participate in such Demand Request) shall be entitled to make no more than two Demand Requests in the aggregate pursuant to the foregoing provisions; and provided further that, with respect to clauses (x) and (y) above, the Company shall not be obligated to effect more than one Demand Registration at the request of any of the Demand Holders in any six-month period. After such time as the Company shall become eligible to use Form S-3 (or comparable form) for the registration under the Securities Act of any of its securities, any Demand Request by a Sponsor Holder with a reasonably anticipated aggregate offering price of at least $50,000,000 may be for a “shelf” registration pursuant to Rule 415 under the Securities Act; provided that if a Sponsor Holder requests that any such “shelf” registration statement remain effective for a period in excess of two years, such “shelf” registration shall count as two Demand Requests for the purposes of this Section 2.1(a).

     (ii) Each Demand Request shall specify the number of shares of Registrable Securities proposed to be sold. Subject to Section 2.3(c), the Company shall use its commercially reasonable efforts to file under the Securities Act a registration statement on an appropriate form to effect the Demand Registration within 45 days if eligible to use Form S-3, otherwise within 75 days if not so eligible to use Form S-3, after receiving a Demand Request (the “Required Filing Date”) and shall use its commercially reasonable efforts to cause the same to be declared effective by the SEC as promptly as practicable after such filing.

     (b) Effective Registration and Expenses. A registration will not count as a Demand Registration until it has become effective (unless the Requesting Holders withdraw their Demand Request, in which case such demand will count as a Demand Registration unless (i) the Requesting Holders pay all Registration Expenses in connection with such withdrawn registration, (ii) during the registration process material adverse information regarding the Company is disclosed that was not known by such Requesting Holders at the time the request for such Demand Registration was made or (iii) the Company has not complied in all material respects with its obligations hereunder required to have been taken prior to such withdrawal); provided that if, after it has become effective, an offering of Registrable Securities pursuant to a registration is interfered with by any stop order, injunction or other order or requirement of the SEC or other governmental agency or court, such registration will be deemed not to have been effected and will not count as a Demand Registration. Notwithstanding the foregoing, if, in connection with the Demand Request made by the Non-Sponsor Demand Holders only, the number of Registrable Securities of such Non-Sponsor Demand Holders included in such registration after giving effect to the provisions of paragraph (d) below is less than 75% of the Non-Sponsor Registrable Securities requested to be included in such registration pursuant to such Demand Request, such Non-Sponsor Demand Holders shall be entitled to make one additional Demand Request, in which case the dollar limitations set forth in paragraph (a) above shall be waived; provided that any Non-Sponsor Demand Holders who elected to opt out of the first Demand Request by the Non-Sponsor Demand Holders shall be entitled to participate in any additional Demand Request hereby granted to the Non-Sponsor Demand Holders.

     (c) Selection of Underwriters. The offering of Registrable Securities pursuant to a Demand Registration requested prior to such time as the Company is eligible to register on a Form S-3 registration statement (or a successor form) the sale of Common Stock requested by

such Demand Registration shall be in the form of an underwritten offering. If the Requesting Holder so indicates, the Requesting Holder shall select the book-running managing Underwriter and such additional Underwriters to be used in connection with the offering; provided that such selections shall be subject to the consent of the Company, and any pre-existing engagement between the Company and any underwriter, which consent shall not be unreasonably withheld.

     (d) Priority on Demand Registrations. No securities to be sold for the account of any Person (including the Company) other than a Requesting Holder shall be included in a Demand Registration if the managing Underwriter(s) shall advise the Requesting Holders that the inclusion of such securities will materially and adversely affect the price or success of the offering (a “Material Adverse Effect”); provided, however, that for purposes of the foregoing, (i) with respect to a Demand Request made by a Sponsor Demand Holder, all other Sponsor Holders who desire to participate in such Demand Registration and, for the first two (2) Demand Requests made by the Sponsor Demand Holders only, all Non-Sponsor Holders who have the right to participate in such Demand Registration in accordance with paragraphs (e) and (f) below or pursuant to an exercise of their rights under Section 2.2, shall be deemed to be Requesting Holders for all purposes other than determining the number of Demand Requests made by such Holders, and (ii) with respect to a Demand Request made by the Non-Sponsor Demand Holders, all of the Non-Sponsor Demand Holders who desire to participate in such Demand Registration shall be deemed to be Requesting Holders and, for the first Demand Request made by the Non-Sponsor Demand Holders only, all Sponsor Holders who have the right to participate in such Demand Registration in accordance with paragraphs (e) and (f) below or pursuant to an exercise of their rights under Section 2.2, shall be deemed to be Requesting Holders for all purposes other than determining the number of Demand Requests made by such Holders. Furthermore, in the event the managing Underwriter(s) shall advise the Requesting Holders that even after exclusion of all securities of other Persons pursuant to the immediately preceding sentence, the amount of Registrable Securities proposed to be included in such Demand Registration by Requesting Holders is sufficiently large to cause a Material Adverse Effect, the Registrable Securities of Requesting Holders to be included in such Demand Registration shall be allocated pro rata among the Requesting Holders on the basis of the number of shares of Common Stock requested to be included in such registration by each such Requesting Holder.

     (e) Multiple Demands. If the Company shall receive, within a period of 15 days, a request to file a registration statement from more than one Person who has the contractual right (whether exercisable alone or in conjunction with other rights) to require the Company to file a registration statement (whether or not such Person is a Demand Holder), only the first such Person requesting the Company to file a registration statement shall be considered a Requesting Holder for the purposes of determining the number of Demand Requests that may be made by such Person pursuant to this Section 2.1, and all other Persons making such requests shall be considered a Requesting Holder for all purposes other than determining the number of Demand Requests made by such Person and provided further that if the request to file such a registration statement was first made by the Non-Sponsor Holders, then any Non-Sponsor Holder who exercises his rights under Section 2.2 hereof shall be deemed a Requesting Holder for all purposes hereunder. In the event the Company shall receive a request to file a Demand Registration Statement from any Person (including a Demand Holder) who has the contractual right to cause the Company to do so, the Company shall promptly (and in any event within five days after its receipt of such request) notify all Demand Holders (in each case who then own

Registrable Securities) thereof (a “Notice,” or with regard to notices of Demand Registrations, a “Demand Registration Notice”).

     (f) Right to Piggyback on Demand Registrations. Any Demand Holder may request to include any or all of such Demand Holder’s Registrable Securities in a Demand Registration by notifying the Company of the number of Registrable Securities such Demand Holder would like to include in the Demand Registration within the 15 days of such Demand Holder’s receipt of the Demand Registration Notice. Any Demand Holder requesting inclusion of Registrable Securities in a Demand Registration shall not be considered a Requesting Holder for purposes of determining the number of Demand Requests that may be made by such Person.

     2.2 Piggy-Back Registration.

     (a) Piggyback Registration Rights. If the Company proposes to file a registration statement under the Securities Act with respect to an offering of any shares of Common Stock by the Company for its own account (including an IPO Registration Statement) or for the account of any holder of Common Stock (including any Holder) (other than a registration statement on Form S-4 or S-8 or any substitute form that may be adopted by the SEC or a Shelf Registration Statement), then the Company shall give written notice of such proposed filing to the Holders of the Registrable Securities as soon as practicable (but, subject to the last sentence in Section 2.1(e), in no event less than 20 days before the anticipated filing date of such registration statement), and such notice shall offer such Holders the opportunity to register such number of Registrable Securities as each such Holder may request (a “Piggyback Registration”). Subject to Section 2.2(b) hereof and any cutback rights applicable to an IPO Registration Statement as set forth in Section 2 of the Registration Rights Agreement, the Company shall include in each such Piggyback Registration all Registrable Securities requested to be included in the registration for such offering by written notice to the Company within 15 days of receipt (in accordance with Section 4.1) of the Company’s notice referred to above; provided, however, that the Company may at any time withdraw or cease proceeding with any such registration for its own account prior to effectiveness of such registration whether or not any Holder of Registrable Securities has elected to include any Registrable Securities in such registration. Each Holder of Registrable Securities shall be permitted to withdraw all or part of such Holder’s Registrable Securities from a Piggyback Registration at any time prior to the effective date thereof.

     (b) Priority on Piggyback and Demand Registration. Subject to any cutback rights applicable to an IPO Registration Statement set forth in Section 2 of the Registration Rights Agreement, the Company shall use commercially reasonable efforts to cause the managing Underwriter(s) of a proposed underwritten offering to permit the Registrable Securities requested to be included in the registration statement for such offering under Section 2.2(a) (“Piggyback Securities”) to be included on the same terms and conditions as any similar securities included therein. Notwithstanding the foregoing, the Company shall not be required to include any Holder’s Piggyback Securities in such offering unless such Holder accepts the terms of the underwriting agreement between the Company and the managing Underwriter(s) and otherwise complies with the provisions of Section 2.7 below. If the managing Underwriter(s) of a proposed underwritten offering (excluding an underwritten offering of shares registered on an IPO Registration Statement which shall be governed by the terms of the Registration Rights Agreement) advise(s) the Company that in their opinion the total amount of securities, including

Piggyback Securities, to be included in such offering is sufficiently large to cause a Material Adverse Effect, then in such event the securities to be included in such offering shall be allocated first to the Requesting Holders if such registration statement is pursuant to a Demand Request or, if not, then to the Company, and then, to the extent that any additional securities can, in the opinion of such managing Underwriter(s), be sold without any such Material Adverse Effect, pro rata among the holders of Piggyback Securities on the basis of the number of Registrable Securities then held by each such holder.

     2.3 Holdback Agreements.

     (a) Restrictions on Public Sale by Holder of Registrable Securities. Following any underwritten public offering of equity securities by the Company or any Holder of Registrable Securities effected pursuant to this Agreement, each Holder of Registrable Securities agrees not to effect any public sale or distribution of securities similar to those being registered or of any securities convertible into or exchangeable or exercisable for such securities or hedging transactions relating to the Registrable Securities, including a sale pursuant to Rule 144 under the Securities Act, during the 14 days prior to the expected date of “pricing” of such offering and during such period, not to exceed 180 days with respect to a Qualified Public Offering or 60 days with respect to any subsequent offering, beginning on the date of such final prospectus (or prospectus supplement if the offering is made pursuant to a “shelf” registration) as shall be reasonably requested by the managing Underwriter(s) except as part of such registration, and, if and to the extent requested by the managing Underwriter(s), each such Holder of Registrable Securities agrees to execute an agreement to the foregoing effect with the Underwriter(s) for such offering on such terms as the managing Underwriter(s) shall reasonably request.

     (b) Restrictions on Public Sale by the Company. Following any underwritten public offering of equity securities by any Holder of Registrable Securities effected pursuant to this Agreement, the Company agrees not to effect any public sale or distribution of any securities similar to those being registered, or any securities convertible into or exchangeable or exercisable for such securities, during the 14 days prior to the expected date of “pricing” of such offering and during such period, not to exceed 180 days with respect to a Qualified Public Offering or 60 days with respect to any subsequent offering, beginning on the date of such final prospectus (or prospectus supplement if the offering is made pursuant to a “shelf” registration) as shall be reasonably requested by the managing Underwriter(s) except as part of such registration as permitted hereby.

     (c) Deferral of Filing. The Company may defer the filing (but not the preparation) of a registration statement required by Section 2.1 if (i) at the time the Company receives the Demand Request, the Company or any of its subsidiaries are engaged in confidential negotiations or other confidential business activities, disclosure of which would be required in such registration statement (but would not be required if such registration statement were not filed) and the Board determines in good faith that such disclosure would be materially detrimental to the Company, until a date not later than 60 days after the Required Filing Date or (ii) subject to Section 2.1(e), the Company had received, prior to receiving such Demand Request, a Demand Request from a different group of Requesting Holders (a “Preferred Request”) and is proceeding with reasonable diligence to comply with the Preferred Request, until a date not later than the later of (A) six months after the effective date of such Preferred Request or (B) the end

of the holdback period referred to in Section 2.3(a) above with respect to such Preferred Request or (iii) prior to receiving such Demand Request, the Board had determined to effect a registered underwritten public offering of the Company’s equity securities for the Company’s account and the Company had taken substantial steps (including, but not limited to, selecting or entering into a letter of intent with the managing Underwriter(s) for such offering) and is proceeding with reasonable diligence to effect such offering, until a date not later than the end of the holdback period referred to in Section 2.3(a) above with respect to such offering. A deferral of the filing of a registration statement pursuant to this Section 2.3(c) shall be lifted, and the requested registration statement shall be filed as soon as reasonably practicable, if, in the case of a deferral pursuant to clause (i) of the preceding sentence, the negotiations or other activities are disclosed or terminated, or, in the case of a deferral pursuant to clause (ii) of the preceding sentence, the Preferred Request is withdrawn, or in the case of a deferral pursuant to clause (iii) of the preceding sentence, the proposed registration for the Company’s account is abandoned. In order to defer the filing of a registration statement pursuant to this Section 2.3(c), the Company shall promptly, upon determining to seek such deferral, deliver to each Requesting Holder a certificate signed by the Chief Executive Officer of the Company stating that the Company is deferring such filing pursuant to this Section 2.3(c) and the basis therefor in reasonable detail. Within 20 days after receiving such certificate, the Holders of a majority of the Registrable Securities held by the Requesting Holders and for which registration was previously requested may withdraw such request by giving notice to the Company. If withdrawn, the Demand Request shall be deemed not to have been made for all purposes of this Agreement. The Company may defer the filing of a Demand Registration pursuant to this Section 2.3(c) only one time during any 12-month period. Nothing in this paragraph shall affect the rights of the Holders under Section 2.2 to participate in any such Demand Registration at such time as the filing deferral is lifted in accordance with this Section 2.3(c).

     (d) Use, and Suspension of Use, of Shelf Registration Statement. If the Company has filed a “shelf” registration statement and has included Registrable Securities therein, the Company shall be entitled to suspend, for a reasonable period of time not in excess of 90 days, the offer or sale of Registrable Securities pursuant to such registration statement by any holder of Registrable Securities if (i) a “road show” is not then in progress with respect to a proposed offering of Registrable Securities by such holder pursuant to such registration statement and such holder has not executed an underwriting agreement with respect to a pending sale of Registrable Securities pursuant to such registration statement and (ii) the Company or any of its subsidiaries are engaged in confidential negotiations or other confidential business activities, disclosure of which would be required if such registration statement were used (but would not be required if such registration statement were not used) and the Board determines in good faith that such disclosure would be materially detrimental to the Company. In order to suspend the use of the registration statement pursuant to this Section 2.3(d), the Company shall promptly, upon determining to seek such suspension, deliver to the holders of Registrable Securities included in such registration statement, a certificate signed by the Chief Executive Officer of the Company stating that the Company is suspending use of such registration statement pursuant to this Section 2.3(d) and the basis therefor in reasonable detail. IN ADDITION, A HOLDER OF REGISTRABLE SECURITIES MAY NOT UTILIZE A SHELF REGISTRATION STATEMENT TO EFFECT THE SALE OF ANY SUCH SECURITIES UNLESS SUCH HOLDER HAS GIVEN THE COMPANY AT LEAST ONE BUSINESS DAY ADVANCE WRITTEN NOTICE OF THE DATE OR DATES OF A PROPOSED SALE OF SUCH

SECURITIES BY SUCH HOLDER PURSUANT TO SUCH REGISTRATION STATEMENT (WHICH NOTICE MAY BE GIVEN AS OFTEN AS SUCH HOLDER DESIRES).

     2.4 Registration Procedures. Whenever the Holders have requested that any Registrable Securities be registered pursuant to Section 2.1 hereof, the Company will, at its expense, use commercially reasonable efforts to effect the registration of such Registrable Securities under the Securities Act prior to the Required Filing Date, and in connection with any such request, the Company will as expeditiously as practicable:

     (a) prepare and file with the SEC a registration statement on any form for which the Company then qualifies or which counsel for the Company shall deem appropriate and which form shall be available for the sale of the Registrable Securities to be registered thereunder in accordance with the intended method of distribution thereof, and use commercially reasonable efforts and proceed diligently and in good faith to cause such filed registration statement to become effective under the Securities Act; provided that before filing a registration statement or prospectus or any amendments or supplements thereto, the Company will furnish to all Selling Holders and to one counsel reasonably acceptable to the Company selected by the Selling Holders, copies of all such documents proposed to be filed, which documents will be subject to the review of such counsel; provided further that in connection with a Demand Registration, the Company shall not file any registration statement or prospectus, or any amendments or supplements thereto, if the Requesting Holders who hold a majority of the Registrable Securities covered by such registration statement or their counsel shall reasonably object at least two (2) Business Days prior to the filing thereof;

     (b) prepare and file with the SEC such 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 Section 2.1 for a period (except as provided in the last paragraph of this Section 2.4) of not less than 270 consecutive days (or four years, or such shorter period as the Requesting Holders who hold a majority of the Registrable Securities covered by such registration may elect, if a “shelf registration” is requested) or, if shorter, the period terminating when all Registrable Securities covered by such registration statement have been sold (but not before the expiration of the applicable period referred to in Section 4(3) of the Securities Act and Rule 174 thereunder, if applicable) and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement during such period in accordance with the intended method of disposition by the Selling Holders thereof set forth in such registration statement; provided however that any Selling Holder that has been included on a “shelf” registration statement may request that such Seller Holder’s Common Stock be removed from such registration statement, in which event the Company shall promptly either withdraw such registration statement or file a post-effective amendment to such registration statement removing such Common Stock;

     (c) furnish to each such Selling Holder such number of copies of such registration statement, each amendment and supplement thereto (in each case including all exhibits thereto), the prospectus included in such registration statement (including each preliminary prospectus) and such other documents as such Selling Holder may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Selling Holder;

     (d) notify the Selling Holders promptly, and (if requested by any such Person) confirm such notice in writing, (i) when a prospectus or any prospectus supplement or post-effective amendment has been filed, and, with respect to a registration statement or any post-effective amendment, when the same has become effective under the Securities Act and each applicable state Law, (ii) of any request by the SEC or any other federal or state governmental authority for amendments or supplements to a registration statement or related prospectus or for additional information, (iii) of the issuance by the SEC of any stop order suspending the effectiveness of a registration statement or the initiation of any proceedings for that purpose, (iv) if at any time the representations or warranties of the Company or any Subsidiary contained in any agreement (including any underwriting agreement) contemplated by Section 2.4(i) below cease to be true and correct in any material respect, (v) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose, (vi) of the happening of any event which makes any statement made in such registration statement or related prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any changes in such registration statement, prospectus or documents so that, in the case of the registration statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the prospectus, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and (vii) of the Company’s reasonable determination that a post-effective amendment to a registration statement would be appropriate;

     (e) use commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of a registration statement, or the lifting of any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment;

     (f) cooperate with the Selling Holders and the managing Underwriter(s) to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold, which certificates shall not bear any restrictive legends and shall be in a form eligible for deposit with The Depositary Trust Company;

     (g) use commercially reasonable efforts to register or qualify such Registrable Securities as promptly as practicable under such other securities or blue sky laws of such jurisdictions as any Selling Holder or managing Underwriter reasonably (in light of the intended plan of distribution) requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such Selling Holder or managing Underwriter to consummate the disposition in such jurisdictions of the Registrable Securities owned by such Selling Holder; provided that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this paragraph (g), (ii) subject itself to taxation in any such jurisdiction or (iii) consent to general service of process in any such jurisdiction;

     (h) use commercially reasonable efforts to cause such Registrable Securities to be registered with or approved by such other governmental agencies or authorities, if any, as may be required of the Company to enable the Selling Holder or Selling Holders thereof to consummate the disposition of such Registrable Securities;

     (i) enter into customary agreements (including an underwriting agreement in customary form with customary indemnification provisions) and take such other actions as are reasonably required or advisable in order to expedite or facilitate the disposition of such Registrable Securities, including providing reasonable availability of appropriate members of senior management of the Company to provide customary due diligence assistance in connection with any offering and to participate in customary “road show” presentations in connection with any underwritten offerings in substantially the same manner as they would in an underwritten primary registered public offering by the Company of its Common Stock, after taking into account the reasonable business requirements of the Company in determining the scheduling and duration of any road show;

     (j) make available for inspection by any Selling Holder of such Registrable Securities, any Underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant or other professional retained by any such Selling Holder or Underwriter (collectively, the “Inspectors”), all financial and other records, pertinent corporate documents and properties of the Company (collectively, the “Records”) as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such Inspectors in connection with such registration statement. Each Selling Holder of such Registrable Securities agrees that information obtained by it as a result of such inspections shall be deemed confidential and shall not be used by it as the basis for any market transactions in the securities of the Company or its Affiliates unless and until such is made generally available to the public (other than by such Selling Holder). Each Selling Holder of such Registrable Securities further agrees that it will, as soon as practicable upon learning that disclosure of such Records is sought in a court of competent jurisdiction, give notice to the Company and allow the Company at its expense to undertake appropriate action to prevent disclosure of the Records deemed confidential;

     (k) use commercially reasonable efforts to obtain a comfort letter or comfort letters from the Company’s independent public accountants in customary form and covering such matters of the type customarily covered by comfort letters as the managing Underwriter(s) reasonably request(s);

     (l) otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the SEC, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering a period of twelve months, beginning within three months after the effective date of the registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act;

     (m) use commercially reasonable efforts to cause all such Registrable Securities to be listed on each securities exchange on which similar securities issued by the Company are then

listed or quoted on any inter-dealer quotation system on which similar securities issued by the Company are then quoted;

     (n) if any event contemplated by Section 2.4(d)(vi) above shall occur, as promptly as practicable prepare a supplement or amendment or post-effective amendment to such registration statement or the related prospectus or any document incorporated therein by reference or promptly file any other required document so that, as thereafter delivered to the purchasers of the Registrable Securities, the prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; and

     (o) cooperate and assist in any filing required to be made with the Financial Industry Regulatory Authority and in the performance of any due diligence investigation by any Underwriter, including any “qualified independent underwriter,” or any Selling Holder.

     Notwithstanding anything contained herein to the contrary, the Company hereby agrees that (i) any Demand Registration that is a “shelf” registration pursuant to Rule 415 under the Securities Act shall contain all language (including, without limitation, on the prospectus cover sheet, the principal stockholders’ chart and the plan of distribution) as may be requested by a holder of Registrable Securities. The Company may require each Selling Holder to promptly furnish in writing to the Company such information regarding the distribution of the Registrable Securities as it may from time to time reasonably request and such other information as may be legally required in connection with such registration. Notwithstanding anything herein to the contrary, the Company shall have the right to exclude from any offering the Registrable Securities of any Selling Holder who does not comply with the provisions of the immediately preceding sentence.

     Each Selling Holder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 2.4(d)(vi) hereof, such Selling Holder will forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.4(n) hereof, and, if so directed by the Company, such Selling Holder will deliver to the Company all copies, other than permanent file copies, then in such Selling Holder’s possession, of the most recent prospectus covering such Registrable Securities at the time of receipt of such notice. In the event the Company shall give such notice, the Company shall extend the period during which such registration statement shall be maintained effective (including the period referred to in Section 2.4(b) hereof) by the number of days during the period from and including the date of the giving of notice pursuant to Section 2.4(d)(vi) hereof to the date when the Company shall make available to the Selling Holders of Registrable Securities covered by such registration statement a prospectus supplemented or amended to conform with the requirements of Section 2.4(n) hereof.

     2.5 Registration Expenses. Subject to the provisions in Section 2.1(b) above with respect to a withdrawn Demand Registration, in connection with any registration statement required to be filed hereunder, the Company shall pay the following registration expenses (the “Registration Expenses”):

     (a) all registration and filing fees (including, without limitation, with respect to filings to be made with the Financial Industry Regulatory Authority);

     (b) fees and expenses of compliance with securities or blue sky laws (including reasonable fees and disbursements of counsel in connection with blue sky qualifications of the Registrable Securities);

     (c) printing expenses;

     (d) internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties);

     (e) the fees and expenses incurred in connection with the listing on an exchange of the Registrable Securities if the Company shall choose, or be required pursuant to Section 2.4(m), to list such Registrable Securities;

     (f) reasonable fees and disbursements of counsel for the Company and customary fees and expenses for independent certified public accountants retained by the Company (including the expenses of any comfort letters requested pursuant to Section 2.4(k) hereof);

     (g) the reasonable fees and expenses of any special experts retained by the Company in connection with such registration;

     (h) reasonable fees and expenses of one counsel reasonably acceptable to the Company selected by the Selling Holders incurred in connection with the registration of such Registrable Securities hereunder; and

     (i) fees and expenses of any “qualified independent underwriter” or other independent appraiser participating in any offering pursuant to the rules and regulations of the Financial Industry Regulatory Authority.

     The Company shall not have any obligation to pay any underwriting fees, discounts, or commissions attributable to the sale of Registrable Securities or, except as provided by clause (b), (h) or (i) above, any out-of-pocket expenses of the Holders (or the agents who manage their accounts) or the fees and disbursements of any Underwriter.

     2.6 Indemnification; Contribution.

     (a) Indemnification by the Company. The Company agrees to indemnify and hold harmless each Selling Holder, each Person, if any, who controls such Selling Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the officers, directors, agents, general and limited partners, and employees of each Selling Holder and each such controlling Person from and against any and all losses, claims, damages, liabilities (joint or several), and expenses (including reasonable costs of investigation and attorneys’ fees) arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in any registration statement or prospectus relating to the Registrable Securities or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated

therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or expenses arise out of, or are based upon and in conformity with, any such untrue statement or omission or allegation thereof based upon information furnished in writing to the Company by such Selling Holder or on such Selling Holder’s behalf expressly for use therein. The Company also agrees to indemnify any Underwriter(s) of the Registrable Securities, their officers and directors and each Person who controls such Underwriter(s) on substantially the same basis as that of the indemnification of the Selling Holders provided in this Section 2.6(a).

     (b) Indemnification by Holder of Registrable Securities. Each Selling Holder agrees to indemnify and hold harmless each other Selling Holder, the Company, and each Person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and the officers, directors, agents and employees of each other Selling Holder, the Company and each such controlling Person to the same extent as the foregoing indemnity from the Company to such Selling Holder, but only with respect to information furnished in writing by such Selling Holder or on such Selling Holder’s behalf expressly for use in any registration statement or prospectus relating to the Registrable Securities. The liability of any Selling Holder under this Section 2.6(b) shall be limited to the aggregate cash and property received by such Selling Holder pursuant to the sale of Registrable Securities covered by such registration statement or prospectus.

     (c) Conduct of Indemnification Proceedings. If any action or proceeding (including any governmental investigation) shall be brought or asserted against any Person entitled to indemnification under Section 2.6(a) or 2.6(b) above (an “Indemnified Party”) in respect of which indemnity may be sought from any Person who has agreed to provide such indemnification under Section 2.6(a) or 2.6(b) above (an “Indemnifying Party”), the Indemnified Party shall give prompt written notice to the Indemnifying Party and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Party, and shall assume the payment of all reasonable expenses of such defense. Such Indemnified Party shall have the right to employ separate counsel in any such action or proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless (i) the Indemnifying Party has agreed to pay such fees and expenses or (ii) the Indemnifying Party fails promptly to assume the defense of such action or proceeding or fails to employ counsel reasonably satisfactory to such Indemnified Party or (iii) the named parties to any such action or proceeding (including any impleaded parties) include both such Indemnified Party and Indemnifying Party (or an Affiliate of the Indemnifying Party), and such Indemnified Party shall have been advised by counsel that there may be one or more legal defenses available to the Indemnified Party that are different from or additional to those available to the Indemnifying Party, or there is a conflict of interest on the part of counsel employed by the Indemnifying Party to represent such Indemnified Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense of such action or proceeding on behalf of such Indemnified Party). Notwithstanding the foregoing, the Indemnifying Party shall not, in connection with any one such action or proceeding or separate but substantially similar related actions or proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be liable at any time for the fees and

expenses of more than one separate firm of attorneys (together in each case with appropriate local counsel). The Indemnifying Party shall not be liable for any settlement of any such action or proceeding effected without its written consent (which consent will not be unreasonably withheld), but if settled with its written consent, or if there be a final judgment for the plaintiff in any such action or proceeding, the Indemnifying Party shall indemnify and hold harmless such Indemnified Party from and against any loss or liability (to the extent stated above) by reason of such settlement or judgment. The Indemnifying Party shall not consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release, in form and substance reasonably satisfactory to the Indemnified Party, from all liability in respect of such action or proceeding for which such Indemnified Party would be entitled to indemnification hereunder.

     (d) Contribution. If the indemnification provided for in this Section 2.6 is unavailable to the Indemnified Parties in respect of any losses, claims, damages, liabilities or judgments referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Parties, shall contribute to the amount paid or payable by such Indemnified Parties as a result of such losses, claims, damages, liabilities and judgments as between the Company on the one hand and each Selling Holder on the other, in such proportion as is appropriate to reflect the relative fault of the Company and of each Selling Holder in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and of each Selling Holder on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such Person, and such Person’s relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

     The Company and the Selling Holders agree that it would not be just and equitable if contribution pursuant to this Section 2.6(d) were determined by any method of allocation which does not take into account the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 2.6(d), no Selling Holder shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities of such Selling Holder were offered to the public (less any underwriting discounts or commissions) exceeds the amount of any damages which such Selling Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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 guilty of such fraudulent misrepresentation.

     2.7 Participation in Underwritten Registrations. No Holder may participate in any underwritten registration hereunder unless such Holder (a) agrees to sell such Holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Person entitled hereunder to approve such arrangements and (b) completes and executes all

questionnaires, powers of attorney, custody agreements, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements and this Agreement.

     2.8 Transfers of Registration Rights. The provisions hereof will inure to the benefit of and be binding upon the successors and assigns of each of the parties hereto, except as otherwise provided herein; provided, however, that the registration rights granted hereby may be transferred only (i) by operation of Law or (ii) to any Person to whom a Holder transfers Registrable Securities, provided further that any such transferee shall not be entitled to rights pursuant to Section 2.1, 2.2 or 2.3 hereof unless such transferee of registration rights hereunder agrees to be bound by the terms and conditions hereof and executes and delivers to the Company an acknowledgment and agreement to such effect.

     2.9 Restrictive Legends. Each certificate evidencing shares of Common Stock beneficially owned by a Stockholder, and each certificate issued to any subsequent transferee of such shares of Common Stock permitted hereunder, shall be stamped or otherwise imprinted with a legend in substantially the following form:

THIS CERTIFICATE IS SUBJECT TO RESTRICTIONS ON TRANSFER AND OTHER TERMS AND CONDITIONS SET FORTH IN THE AMENDED AND RESTATED STOCKHOLDERS AGREEMENT, DATED DECEMBER 23, 2010. A COPY OF THE AMENDED AND RESTATED STOCKHOLDERS AGREEMENT MAY BE OBTAINED FROM THE CORPORATION AT ITS PRINCIPAL EXECUTIVE OFFICES.

ARTICLE 3.
OTHER MATTERS

     3.1 Composition of Board; VCOC Management Rights.

          (a) As long as Energy Spectrum owns Common Stock representing at least 10% of the outstanding Common Stock then entitled to vote, the Company agrees to take all action within its power, as shall be required (i) to cause the Board at all times to include at least one member designated by Energy Spectrum (the “Energy Spectrum Director”) and (ii) to cause the Compensation Committee of the Board (the “Compensation Committee”) to be composed of five members, the Energy Spectrum Director, the StepStone/Citi Director subject to the provisions set out in Section 3.1(b), and three non-management directors. Upon the resignation, death, removal, disqualification or other vacancy of any Energy Spectrum Director, Energy Spectrum shall have the right to designate a new director and the Company shall have the same obligations set forth under the first sentence of this Section 3.1(a) to cause the election of such designee to the Board and the appointment of such designee to the Compensation Committee.

          (b) As long as StepStone/Citi owns Common Stock representing at least 10% of the outstanding Common Stock then entitled to vote, the Company agrees to take all action within its power, as shall be required (i) to cause the Board at all times to include at least one member designated by StepStone/Citi (the “StepStone/Citi Director”) and (ii) to cause the Compensation Committee to be composed of five members, the StepStone/Citi Director, the Energy Spectrum Director subject to the provisions set out in Section 3.1(a), and three non-management directors.

          (c) The rights set forth in this Section 3.1 are, in part, intended to satisfy the requirement of contractual management rights for purposes of qualifying the ownership interests of a Sponsor in the Company as venture capital investments for purposes of the Department of Labor’s “plan assets” regulations (“Contractual Management Rights”), and in the event such rights are not satisfactory for such purpose or are lost by reason of the operation of this Agreement, the Company and a Sponsor shall reasonably cooperate in good faith to agree upon mutually satisfactory Contractual Management Rights which satisfy such regulations.

          (d) The Company agrees to take all action within its power as shall be required to cause the Board at all times to include at least three members not affiliated with a Sponsor or management of the Company.

          (e) Each of Energy Spectrum and StepStone/Citi shall have the right to unilaterally terminate its respective rights under this Section 3.1 by giving written notice to the Company that it is irrevocably relinquishing its rights under this Section 3.1.

     4.9 Miscellaneous; Amendment; Termination. The provisions of this Agreement may only be amended by the written consent of the Company and the Sponsor Demand Holders (if the Sponsor Demand Holders then own Registrable Securities); provided, however, that any amendment that has an adverse effect on the rights of, or imposes additional obligations on, the Non-Sponsor Holders shall require the consent of the Non-Sponsor Demand Holders that hold in the aggregate at least 50% of the Registrable Securities then held by the Non-Sponsor Holders (if the Non-Sponsor Holders then own Registrable Securities). The Holders acknowledge and agree that any Person that becomes a Stockholder shall have the rights and obligations set forth in this Agreement and that such Person becoming a Stockholder shall be deemed not to be an amendment to this Agreement. The provisions of this Agreement shall terminate and be of no further force or effect as of and following the fifth anniversary of the date hereof; provided that the provisions of Section 2.6 shall survive for any sales of Registrable Securities prior to such date.
