ARTICLE II

Demand Registration

SECTION 2.01. Requests for Registration. (a) Subject to the terms of this Agreement and the Underwriting Agreement, the Selling Stockholder may at any time request registration by the Company under the Securities Act of all or part of the Registrable Shares on Form S-1 or S-3 or any similar or successor to such forms under the Securities Act.

(b) Any registration requested pursuant to subsection (a) above is referred to herein as a “Demand Registration”. Any request for a Demand Registration (each, a “Notice of Demand”) shall specify (i) the amount of Registrable Shares requested to be registered; and (ii) the intended method or methods and plan of disposition thereof, including whether such requested registration is to involve an underwritten offering. Subject to the terms of the Underwriting Agreement, within 30 calendar days of a Notice of Demand, the Company shall file with the Commission a Registration Statement relating to such Notice of Demand for the offer and sale of the Registrable Shares by the Selling Stockholder from time to time in accordance with the method or methods and plan of disposition elected by the Selling Stockholder and set forth or to be set forth in such Registration Statement and, thereafter, shall use its reasonable best efforts to cause such Registration Statement promptly to be declared effective under (A) the Securities Act; and (B) the “blue sky” laws of such jurisdictions as any seller of Registrable Shares being registered under such Registration Statement or any underwriter, if any, reasonably requests.

(c) It is agreed that at any time when the Company is eligible to file a Registration Statement on Form S-3 (or any successor form), the Selling Stockholder may request that the Company file a Registration Statement pursuant to Rule 415 under the Securities Act to permit the offering of the Registrable Shares on a delayed or continuous basis. Once the Company has become subject to the reporting requirements of the Exchange Act, the Company shall use its reasonable best efforts to make Demand Registrations on Form S-3 or any similar short-form registration statement available for the sale of Registrable Shares.

(d) The registration statement on Form S-1 filed with the Securities and Exchange Commission in connection with the Initial Public Offering shall not constitute a Demand Registration for any purpose under this Agreement.

SECTION 2.02. Continued Effectiveness. The Company shall use its reasonable best efforts to keep any Registration Statement filed pursuant to Section 2.01(b) continuously effective under the Securities Act in order to permit the Prospectus forming a part thereof to be usable by the Selling Stockholder until the earlier of (i) the date as of which all Registrable Shares have been sold pursuant to the Registration Statement or another registration statement filed under the Securities Act (but in no event prior to the applicable period referred to in Section 4(3) of the Securities Act and Rule 174 thereunder); and (ii) the date as of which the Selling Stockholder is permitted to sell the Registrable Shares without registration pursuant to Rule 144 under the Securities Act without volume limitation or other restrictions on transfer thereunder (such period of effectiveness, the “Registration Period”). Subject to Section 2.03, the Company shall not be deemed to have used its reasonable best efforts to keep the Registration Statement effective during the Registration Period if the Company voluntarily takes any action or omits to take any action that would result in the Selling Stockholder not being able to offer and sell any Registrable Shares pursuant to such Registration Statement during the Registration Period, unless such action or omission is required by applicable law.

SECTION 2.03. Restrictions. The Company shall not be obligated to effect any Demand Registration to the extent that the closing date for the sale of Registrable Shares pursuant to such Demand Registration would be less than 120 calendar days after the closing date for the sale of Registrable Shares pursuant to a previous Demand Registration. If the filing, initial effectiveness or continued use of a Registration Statement at any time would require the Company to make an Adverse Disclosure, the Company may, after consultation with the Selling Stockholder in good faith, delay the filing or initial effectiveness (but not the preparation) of, or suspend use of, the Registration Statement by written notice of

such action to the Selling Stockholder (a “Demand Suspension”); provided, however, that the Company shall not be permitted to exercise a Demand Suspension (i) more than once during any one-year period or (ii) for any period exceeding 30 calendar days. In the case of a Demand Suspension, the Selling Stockholder agrees to suspend use of the applicable Prospectus and any Free Writing Prospectuses in connection with any sale or purchase, or offer to sell or purchase, Registrable Shares, upon receipt of the notice referred to above. The Company shall promptly notify the Selling Stockholder upon the termination of any Demand Suspension, amend or supplement the Prospectus (including by means of an Issuer Free Writing Prospectus), if necessary, so it does not contain any untrue statement or omission of a material fact and furnish to the Selling Stockholder such numbers of copies of the Prospectus and any applicable Issuer Free Writing Prospectus as so amended or supplemented as the Selling Stockholder may reasonably request. The Company agrees, if necessary, to amend or supplement the Registration Statement, if required by the registration form used by the Company, by the instructions applicable to such registration form, by the Securities Act or the rules or regulations promulgated thereunder, or as may reasonably be requested by the Selling Stockholder.

SECTION 2.04. Selection of Underwriters. In connection with any Demand Registration, the Selling Stockholder shall have the sole right to select the nationally recognized investment banker(s) and manager(s) to administer the offering.

SECTION 2.05. Priority on Demand Registrations. If the Company proposes to sell any Equity Securities in a Demand Registration and the managing underwriters advise the Board of Directors in writing that in their opinion the total number of shares of Equity Securities (including the Registrable Shares) requested to be included in the registration would create a substantial risk of materially and adversely affecting the ability of the underwriters to effect such offering, then the Company shall promptly provide the Selling Stockholder with a copy of such opinion and consult with the Selling Stockholder with respect to such opinion, and after such consultation shall include in such registration only such number of shares of Equity Securities (including the Registrable Shares), if any, which the managing underwriters determine can be sold in such offering without materially and adversely affecting the ability of the underwriters to execute such offering. The Company shall include in such Demand Registration (i) first, 100% of the Equity Securities that the Company proposes to sell in such Demand Registration as part of a Permitted Company Offering; (ii) second, 100% of the Registrable Shares requested to be registered by the Selling Stockholder, or such lesser amount determined by the managing underwriters pursuant to the preceding sentence; and (iii) third, only if all of the Equity Securities referred to in clauses (i) and (ii) have been included, any other Equity Securities requested to be included therein that the managing underwriters have determined can be included pursuant to the preceding sentence.

ARTICLE III

Piggyback Registration

SECTION 3.01. Right to Piggyback. Whenever the Company proposes to register any of its Equity Securities under the Securities Act (except (a) on Forms S-4 or S-8 or any successor form to such forms or as part of any registration of securities for offering and sale to employees or directors of the Company pursuant to any employee stock plan or other employee benefit plan arrangement or (b) pursuant to a Demand Registration), including, in the case of the Equity Units, by amending the Equity Units Registration Statement, the Company shall (i) as soon as practicable (but in no event less than 30 calendar days prior to the proposed date of filing of the related Registration Statement), give written notice to the Selling Stockholder), of its intention to effect such a registration; and (ii) shall register under such Registration Statement all Registrable Shares (in accordance with the priorities set forth in Sections 3.02 and 3.03 below) with respect to which the Company shall have received written requests therefor within 15 calendar days after delivery of the Company’s notice (each such registration, a “Piggyback Registration”).

SECTION 3.02. Priority on Primary Registrations. If a Piggyback Registration is an underwritten primary registration on behalf of the Company and the managing underwriters advise the Board of Directors in writing that in their opinion the total number of shares of Equity Securities (including

the Registrable Shares) requested to be included in the registration would create a substantial risk of materially and adversely affecting the ability of the underwriters to effect such offering, then the Company shall promptly provide the Selling Stockholder with a copy of such opinion and consult with the Selling Stockholder with respect to such opinion, and after such consultation shall include in such registration only such number of shares of Equity Securities (including the Registrable Shares), if any, which the managing underwriters determine can be sold in such offering without materially and adversely affecting the ability of the underwriters to execute such offering. The Company shall include in such Piggyback Registration (i) first, 100% of the Equity Securities that the Company proposes to sell as part of a Permitted Company Offering; (ii) second, only if all of the Equity Securities referred to in clause (i) have been included, if the Selling Stockholder participates in such registration, 100% of the Registrable Shares that the Selling Stockholder proposes to sell, or such lesser amount determined by the managing underwriters pursuant to the preceding sentence; and (iii) third, only if all of the Equity Securities referred to in clauses (i) and (ii) have been included, any other Equity Securities requested to be included therein that the managing underwriters have determined can be included pursuant to the preceding sentence.

SECTION 3.03. Priority on Secondary Registrations. If a Piggyback Registration is an underwritten secondary registration on behalf of any Person other than the Selling Stockholder (the “Other Stockholder”) and the managing underwriters advise the Board of Directors in writing that in their opinion the total number of shares of Equity Securities (including the Registrable Shares) requested to be included in the registration would create a substantial risk of materially and adversely affecting the ability of the underwriters to effect such offering, then the Company shall promptly provide the Selling Stockholder with a copy of such opinion and consult with the Selling Stockholder with respect to such opinion, and after such consultation shall include in such registration only such number of shares of Equity Securities (including the Registrable Shares) which the managing underwriters determine can be sold in such offering without materially and adversely affecting the ability of the underwriters to execute such offering. The Company shall include in such registration (i) first, 100% of the Registrable Shares that the Selling Stockholder proposes to sell and, if the Other Stockholder has registration rights granted by the Company with the approval of the Selling Stockholder, 100% of the Equity Securities that such Other Stockholder proposes to sell, allocated, if necessary, pro rata between the Selling Stockholder and such Other Stockholder on the basis of the number of shares of Common Stock owned by each such person; and (ii) second, only if all the Equity Securities referred to in clause (i) have been included, any other securities requested to be included therein that the managing underwriters have determined can be included pursuant to the preceding sentence.

SECTION 3.04. Selection of Underwriters. If a Piggyback Registration involves an underwritten primary registration on behalf of the Company or any Other Stockholder, the managing underwriter or underwriters thereof shall be selected by the Company, subject to the Selling Stockholder’s approval, which approval shall not be unreasonably withheld or delayed.

SECTION 3.05. Limitations on Registrations. The Company shall not register any of its securities for sale for its own account (other than securities issued to employees of the Company under an employee benefit plan or securities issued to effect a business combination pursuant to Rule 145 promulgated under the Securities Act) except as a firm commitment underwriting.

SECTION 3.06. No Effect on Demand Registrations. No registration or designation of Registrable Shares effected pursuant to a request under this Article III shall be deemed to have been effected pursuant to Article II or shall relieve the Company of its obligations under Article II.

ARTICLE IV

Registration Procedures

Whenever the Selling Stockholder shall have made a Notice of Demand or requested a Piggyback Registration, the Company shall use all reasonable and diligent efforts to effect the registration and sale of Registrable Shares in accordance with the intended method or methods of disposition thereof and, pursuant thereto, the Company shall as expeditiously as possible:

Selling Stockholder shall be deemed to have agreed that the Selling Stockholder shall forthwith discontinue such disposition of Registrable Shares pursuant to such Registration Statement and Prospectus until the receipt of the copies of the amended or supplemented Prospectus or Issuer Free Writing Prospectus contemplated by this Article IV and, if so directed by the Company, shall deliver to the Company all copies, other than permanent file copies, then in its possession of the Prospectus relating to such Registrable Shares current at the time of receipt of such notice;

(i) make available for inspection by the Selling Stockholder, any underwriter participating in any sale or other disposition pursuant to such Registration Statement, and any legal counsel, accountant or other agent retained by the Selling Stockholder or any underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors, employees, counsel and independent registered public accountants to supply all information reasonably requested by the Selling Stockholder or such seller, underwriter, counsel, accountant or agent in connection with such Registration Statement (including the opportunity to discuss the business of the Company with its officers and the independent registered public accountants who have certified its financial statements) as shall be necessary, in the opinion of their respective counsel, to conduct a reasonable investigation within the meaning of the Securities Act; and give the Selling Stockholder and its counsel, accountant or agent and each underwriter the opportunity to participate in the preparation of such Registration Statement, each Prospectus included therein or each Prospectus filed with the Commission in connection therewith;

The Selling Stockholder agrees not to effect any public sale or distribution of Equity Securities during the period beginning seven calendar days before and ending 90 calendar days (or such lesser period as may be permitted by the Company or the managing underwriter or underwriters) after the effective date of the Registration Statement filed in connection with any underwritten public offering of Equity Securities (or, in the case of an offering on Form S-3, the date of the closing under the underwriting agreement in connection therewith), unless the managing underwriter or underwriters thereof shall otherwise agree.

SECTION 6.02. Company’s Agreements. The Company agrees (a) not to file any registration statement relating to the public sale or distribution of Equity Securities by the Company or any of its Affiliates (other than the Selling Stockholder), other than any such sale or distribution consisting solely of a Permitted Company Offering, without the prior written consent of the Selling Stockholder, and (b) not to effect any public sale or distribution of Equity Securities during the period beginning seven calendar days before and ending 90 calendar days (or such lesser period as may be permitted by the managing underwriter or underwriters) after the effective date of the Registration Statement filed in connection with any underwritten public offering of Equity Securities (or, in the case of an offering on Form S-3, the date of the closing under the underwriting agreement in connection therewith), other than any such sale or distribution consisting solely of a Permitted Company Offering, unless the managing underwriter or underwriters thereof shall otherwise agree. Notwithstanding the foregoing, the Company may effect a public sale or distribution of Equity Securities during the periods described above if such sale

or distribution is made pursuant to registrations on Form S-4 or S-8 or any successor form to such forms or as part of any registration of securities for offering and sale to employees or directors of the Company pursuant to any employee stock plan or other employee benefit plan arrangement. The Company agrees to use its reasonable best efforts to obtain from each holder of restricted securities of the Company which securities are the same as or similar to the Registrable Shares being registered, or any restricted securities convertible into or exchangeable or exercisable for any such securities, an agreement not to effect any public sale or distribution of such securities during any period referred to in this paragraph, except as part of any such underwritten public offering, if permitted.

ARTICLE VII

Other Agreements

(a) The Selling Stockholder represents that it has not prepared or had prepared on its behalf or used or referred to, and agrees that it will not prepare or have prepared on its behalf or use or refer to, any Free Writing Prospectus, and has not distributed and will not distribute any written materials in connection with the offer or sale of the Equity Securities without the prior written consent of the Company (which consent shall not be unreasonably withheld or delayed) and, in connection with any underwritten offering, the underwriters. Any such Free Writing Prospectus consented to by the Company and the underwriters, as the case may be, is hereinafter referred to as a “Permitted Free Writing Prospectus”. The Company represents and agrees that it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(b) If requested by the Selling Stockholder or the underwriter(s) for any underwritten offering pursuant to a Demand Registration or a Piggyback Registration, the Company shall enter into an underwriting agreement with such underwriter(s) for such offering, such agreement to contain such representations and warranties by the Company and such other terms as are generally prevailing in agreements of this type. In any such case, the Company shall allow the Selling Stockholder and its counsel to participate in the negotiation of such underwriting agreement, and approve its terms, such approval not to be unreasonably withheld or delayed. The Selling Stockholder shall be a party to such underwriting agreement and may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such underwriter(s) shall also be made to and for the benefit of the Selling Stockholder and that any or all of the conditions precedent to the obligations of such underwriters(s) under such underwriting agreement be conditions precedent to the obligations of the Selling Stockholder thereunder. The Selling Stockholder shall not be required to make any representations or warranties to or agreements with the Company in connection with any Demand Registration or Piggyback Registration other than representations, warranties or agreements regarding the Selling Stockholder, the Selling Stockholder’s title to the Registrable Shares, the Selling Stockholder’s intended method or methods of distribution and any other representation required by law. No Person other than the Selling Stockholder may participate in any registration hereunder which is underwritten unless such Person (i) agrees to sell its securities on the basis provided in such underwriting agreement; and (ii) completes and executes all questionnaires, powers of attorney (which may contain customary terms regarding the minimum price of the Registrable Shares to be sold in the subject offering), custody agreements, indemnities and other documents reasonably required under the terms of such underwriting agreement.

ARTICLE VIII

Indemnification and Contribution

SECTION 8.01. Indemnification. (a) The Company agrees to indemnify and hold harmless RWE, the Selling Stockholder and, in the case of an underwritten offering, each underwriter, their respective officers and directors and each Person who controls (within the meaning of the Securities Act) RWE, the Selling Stockholder or any underwriter, as applicable (collectively, the “Indemnified Parties”), from and against any and all losses, penalties, judgments, suits, costs, claims, damages, liabilities and

expenses (including, but not limited to, reasonable attorney’s fees and disbursements but excluding taxes imposed as a result of being a direct or indirect owner of the Equity Securities or realizing income or gain with respect thereto) (collectively, “Losses”), incurred by, imposed upon or asserted against any of the Indemnified Parties as a result of, relating to or arising out of any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus, Issuer Free Writing Prospectus or any amendment thereof or supplement thereto, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, whether or not relating to a Demand Registration or a Piggyback Registration, except insofar as the same are made in reliance upon and in conformity with any information furnished in writing to the Company by the Selling Stockholder expressly for use in such Registration Statement, Prospectus or preliminary Prospectus, Issuer Free Writing Prospectus or such amendment thereof or supplement thereto or caused by the Selling Stockholder’s failure to deliver a copy of such Prospectus, Issuer Free Writing Prospectus or such amendment thereof or supplement thereto after the Company has furnished the Selling Stockholder with a sufficient number of copies of the same. Unless and until a final and non-appealable judicial determination shall be made that an Indemnified Party is not entitled to indemnification, the Company shall pay or reimburse each Indemnified Party for all indemnified Losses as they are incurred; provided that if a final and non-appealable judicial determination shall be made that such Indemnified Party is not entitled to be indemnified for Losses, such Indemnified Party shall repay to the Company the amount of such Losses for which the Company shall have paid or reimbursed such Indemnified Party.

(b) In connection with any Registration Statement in which the Selling Stockholder is participating pursuant to a Demand Registration or Piggyback Registration, the Selling Stockholder agrees, as a condition of the Company’s obligation to indemnify, to furnish to the Company in writing such information as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and shall indemnify and hold harmless the Company, its officers and directors and each Person who controls (within the meaning of the Securities Act) the Company (collectively, the “Indemnified Company Parties”) from and against any and all Losses incurred by, imposed upon or asserted against any of the Indemnified Company Parties as a result of, relating to or arising out of (i) any untrue or alleged untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus, Issuer Free Writing Prospectus or any amendment thereof or supplement thereto, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, but only to the extent that the same are made in reliance upon and in conformity with any information furnished in writing to the Company by the Selling Stockholder expressly for use in such Registration Statement, Prospectus or preliminary Prospectus, Issuer Free Writing Prospectus or such amendment thereof or supplement thereto; and (ii) any Free Writing Prospectus used by the Selling Stockholder without the prior consent of the Company; provided that the liability of the Selling Stockholder shall be in proportion to and limited in all events to the net proceeds received by the Selling Stockholder from the sale of Registrable Shares pursuant to such Registration Statement.

SECTION 8.02. Contribution. (a) To the extent the indemnification provided for in Section 8.01 hereof is unavailable to an indemnified Person or insufficient in respect of any Losses referred to therein, then an indemnifying Person, in lieu of indemnifying such indemnified Person thereunder, shall contribute to the amount paid or payable by such indemnified Person as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the indemnifying Person on the one hand and of the indemnified Person on the other hand in connection with the acts, statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. In connection with any Registration Statement filed with the Commission by the Company, the relative fault of the Company on the one hand and RWE and the Selling Stockholder on the other hand shall be determined by reference to, among other things, whether any 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 the Company or by the Selling Stockholder and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(b) The Company, RWE and the Selling Stockholder agree that it would not be just or equitable if contribution pursuant to this Section 8.02 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in Section 8.02(a) hereof. The amount paid or payable by an indemnified Person as a result of the Losses referred to in Section 8.02(a) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified Person in connection with investigating or defending any action or claim for Losses (a “Claim”). Notwithstanding the provisions of this Section 8.02, in connection with any Registration Statement filed by the Company, RWE and the Selling Stockholder shall not be required to contribute any amount in excess of the net proceeds received by the Selling Stockholder from the sale of Registrable Shares registered under such Registration Statement. 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. The remedies provided for in this Section 8.02 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified Person at law or in equity.

SECTION 8.03. Procedures. Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying Person of any Claim with respect to which it seeks indemnification; and (ii) unless in such indemnified Person’s reasonable judgment a conflict of interest between such indemnified and indemnifying Persons may exist with respect to such Claim, the indemnifying Person shall have the absolute right, in its sole discretion and expense, to elect to defend, contest or otherwise protect against any such Claim with legal counsel of its own selection, reasonably satisfactory to the indemnified Person. The indemnified Person shall have the right, but not the obligation, to participate, at its own expense, in the defense thereof through counsel of its own choice and shall have the right, but not the obligation, to assert any and all cross-claims or counterclaims it may have. If the indemnifying Person elects to assume the defense of such Claim, the indemnifying Person shall not be subject to any liability for any settlement made by the indemnified Person without its consent (but such consent shall not be unreasonably withheld or delayed). An indemnifying Person who is not entitled to, or elects not to, assume the defense of a Claim shall not be obligated to pay the fees and expenses of more than one counsel (plus any local counsel) for all Persons indemnified by such indemnifying Person with respect to such Claim, unless in the reasonable judgment of any indemnified Person a conflict of interest may exist between such indemnified Person and any other of such indemnified Persons with respect to such Claim. The indemnified Persons shall, and shall cause their Affiliates to, at all times cooperate in all reasonable ways with, make their relevant files and records available for inspection and copying by, and make their employees available or otherwise render reasonable assistance to, the indemnifying Person (i) in its defense of any Claim; and (ii) its prosecution under the last sentence of this Section 8.03 of any related claim, cross-complaint, counterclaim or right of subrogation. In the event the indemnifying Person fails timely to defend, contest or otherwise protect against any such Claim, the indemnified Person shall have the right, but not the obligation, to defend, contest, assert cross-claims or counterclaims or otherwise protect against the same.

SECTION 8.04. Survival. The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified Person or any officer, director or controlling Person of such indemnified Person and shall survive the transfer of securities.

ARTICLE IX

Compliance With Rule 144

If the Selling Stockholder proposes to sell securities in compliance with Rule 144 under the Securities Act, at its request, the Company shall (i) forthwith furnish to the Selling Stockholder a written statement of compliance with the filing requirements of the Commission as set forth in Rule 144, as such rule may be amended from time to time; and (ii) make available to the public and the Selling Stockholder such information as will enable the Selling Stockholder to make sales pursuant to Rule 144.
