NOW, THEREFORE, in consideration of the mutual agreements contained herein, the parties hereto agree as follows:

ARTICLE I

GOVERNANCE AND MANAGEMENT OF THE COMPANY

1.1 Voting; Certain Actions.

(a) Each Stockholder shall vote or cause to be voted all of its Voting Securities, and shall take or cause to be taken all other necessary or desirable actions within such Stockholder’s control (including, without limitation, attending meetings in person or by proxy for purposes of obtaining a quorum and execution of written consents in lieu of meetings), and the Company shall take or cause to be taken all necessary and desirable actions within its control (including, without limitation, calling special board and stockholder meetings), to cause the election, removal and replacement of directors (including the election of the President and Chief Executive Officer as a director) in the manner contemplated in, and otherwise give the fullest effect possible to, the provisions of the Certificate of Incorporation.

(b) Each Stockholder, in connection with any vote or action by written consent of the stockholders of the Company relating to any matter requiring prior approval by the Board in accordance with the provisions of the Certificate of Incorporation, (i) shall vote or cause to be voted all of its Voting Securities against (and not act by written consent to approve) such matter if such matter has not received such required approval by the Board and (ii) otherwise shall use its commercially reasonable efforts to take or cause to be taken all other reasonable actions, at the expense of the Company, required, to the extent permitted by Applicable Law, to prevent the taking of any action by the Company that has not received such required approval by the Board.

2 (c) Insofar as the Company or any of its Subsidiaries becomes subject to requirements under Applicable Law or the regulations of any self-regulatory organization relating to the composition of the Board or its Committees, their respective responsibilities or the qualifications of their respective members, each of the Common Stockholders shall cooperate in good faith to select their respective nominees to the Board under the Certificate of Incorporation so as to permit the Company to comply with all such applicable requirements.

1.2 Chief Executive Officer; Management. The Chief Executive Officer shall be appointed by the Board and may be removed with or without cause by the Board, in each case, in the manner set forth in the Certificate of Incorporation. The compensation and benefits of the Chief Executive Officer, and any employee of the Company or any Subsidiary of the Company who reports directly to the Chief Executive Officer, shall be determined by the Compensation Committee, and in the case of the compensation and benefits of the Chief Executive Officer only, subject also to the approval of the Board (acting upon recommendation of the Compensation Committee).

1.3 Information; Access.

(a) Information. The Company shall provide each Stockholder or its designated Representative with:

(i) as soon as available, and in any event within 60 days after the end of each fiscal quarter of the Company for the first three fiscal quarters of a fiscal year, the consolidated balance sheet of the Company and its Subsidiaries as at the end of such quarter and the consolidated statements of income, cash flows and changes in stockholders’ equity for such quarter and the portion of the fiscal year then ended of the Company and its Subsidiaries;

(ii) as soon as available, and in any event within 105 days after the end of each fiscal year of the Company, the consolidated balance sheet of the Company and its Subsidiaries as at the end of each such fiscal year and the consolidated statements of income, cash flows and changes in stockholders’ equity for such year of the Company and its Subsidiaries, accompanied by the report of independent certified public accountants of recognized national standing; and

(iii) whether or not required by Applicable Law or pursuant to the terms of any outstanding indebtedness of the Company, any annual reports on Form 10-K, quarterly reports on Form 10-Q and reports on Form 8-K(without exhibits) pursuant to Section 13 or 15(d) of the Exchange Act, in such form and at such times (subject to a 15-day grace period) as the Company would be required by Applicable Law to prepare such reports if the Company were a publicly reporting company.

(b) Access. If requested by a Stockholder that (together with its Permitted Transferees) is a holder of an aggregate number of shares of Common Stock representing at least 5% of the issued and outstanding shares of Common Stock, the Company shall, and shall cause its Subsidiaries, officers, directors and employees to, (i) provide to the Representatives of such Stockholder such additional information regarding the Company’s and its Subsidiaries’ affairs, finances and accounts as each such Stockholder may reasonably request upon reasonable notice and (ii) provide to the Representatives of such Stockholder designated by the Stockholder, during normal business hours, upon reasonable notice and at such Stockholder’s expense, reasonable access to the books and records of the Company and its Subsidiaries.

(c) Additional Information. Each of the Stockholders agrees that, from the date of this Agreement and for so long as it shall own any Equity Securities, it will furnish the Company such necessary information and reasonable assistance as the Company may reasonably request in connection with (i) the consummation of the transactions contemplated by this Agreement and the Registration Rights Agreement and (ii) the preparation and filing of any reports, filings, applications, consents or authorizations with any Governmental Entity under any Applicable Law. Each Stockholder proposing to make a Transfer pursuant to Article II shall provide the Company with any information reasonably requested by the Company in order to determine whether the proposed Transfer would be a Prohibited Transaction.

1.4 Corporate Opportunities. Except as otherwise provided in the second sentence of this Section 1.4, (i) no Stockholder and no stockholder, member, manager, partner or Affiliate of any Stockholder or their respective officers, directors, employees or agents (even if also an officer or director of the Company) (any of the foregoing, a “Stockholder Group Member”) shall have any duty to communicate or present an investment or business opportunity or prospective economic advantage to the Company or any of its Subsidiaries in which the Company or one of its Subsidiaries may, but for the provisions of this Section 1.4, have an interest or expectancy (“Corporate Opportunity”), and (ii) no Stockholder or any Stockholder Group Member (even if also an officer or director of the Company) will be deemed to have breached any fiduciary or other duty or obligation to the Company by reason of the fact that any such Person pursues or acquires a Corporate Opportunity for itself or its Affiliates or directs, sells, assigns or transfers such Corporate Opportunity to another Person or does not communicate information regarding such Corporate Opportunity to the Company. The Company, on behalf of itself and its Subsidiaries, renounces any interest in a Corporate Opportunity and any expectancy that a Corporate Opportunity will be offered to the Company; provided that the Company does not renounce any interest or expectancy it may have in any Corporate Opportunity that is offered to an officer or director of the Company in his or her capacity as an officer or director of the Company, whether or not such individual is also an officer or director of a Stockholder, if such Corporate Opportunity is offered to such individual because the Person offering such Corporate Opportunity specifically wishes to do business with the Company or any of its Subsidiaries, and the Stockholders recognize that the Company reserves such rights.

Nothing herein shall be construed to require any person to breach a duty of loyalty to such person’s employer.

1.5 Certain Understandings. Each party to this Agreement acknowledges that the initial holder of the Class B Common Stock and its Affiliates (collectively, the “Class B Holder”) will engage in transactions with the Company and its Subsidiaries pursuant to certain Master ISDA Agreements (as defined in the Certificate of Incorporation). Neither this Agreement nor the Master ISDA Agreements shall preclude the Class B Holder from engaging in transactions of a nature like the transactions contemplated by the Master ISDA Agreements with any other Person. Without limiting the foregoing, each party acknowledges that the Class B Holder is engaged in, among other things, dealing in fuel, and power and related commodities for its own account in the U.S. wholesale fuel and power markets, and manages positions in fuel and power and related commodities for others. The Class B Holder may (i) take actions under the Master ISDA Agreements that may be different than the actions the Class B Holder takes for its own account or for the account of others, even though the circumstances may be the same or similar and (ii) effect transactions with counterparties that are also counterparties to other transactions in fuel and/or power or related commodities with the Class B Holder or for which the Class B Holder is acting in an agency capacity. The Class B Holder may from time to time take proprietary positions and/or make a market in commodities and/or instruments identical or economically related to the transactions contemplated by the Master ISDA Agreements, or may have an investment banking or other commercial relationship with and access to information from the issuer(s) of financial instruments or other interests underlying such transactions during the term of the Master ISDA Agreements. The Class B Holder may also undertake lawful proprietary activities, including hedging transactions related to the initiation or termination of a transaction, that may adversely affect the market price, rate, index or other market factor(s) underlying the transactions contemplated by the Master ISDA Agreements and consequently the value of the transactions contemplated by the Master ISDA Agreements. The parties acknowledge that the relationship between the Class B Holder and the Company and its Subsidiaries under the Master ISDA Agreements is a commercial and not a fiduciary relationship and that neither the Master ISDA Agreements nor this Agreement (except as expressly set forth herein) shall limit in any manner the ability of the Class B Holder to enter into any transaction of any nature with any other Person, provided that the Class B Holder must establish an information wall within its organization so that any Information it obtains in its capacity as a Stockholder or that is disclosed to the Class B Director is kept confidential and is not used by the Class B Holder other than in connection with the operation of the Company and its Subsidiaries, and provided further, for the avoidance of doubt, that nothing in this Section 1.5 relieves the Class B Holder of its obligations under Section 4.2.

1.6 Termination of Certain Rights. In connection with a proposed IPO, if the managing underwriter or underwriters thereof advise the Company in writing that in its or their opinion the retention of any provision(s) contained in Sections 1.1 or 1.2 of this Agreement or Article X of the Certificate of Incorporation would be reasonably expected

to have a material adverse effect on the success of the offering (including, without limitation, a material impact on the selling price), the Stockholders shall negotiate in good faith with each other to amend one or more of such provisions to the extent necessary to avoid having such a material adverse effect on the success of the IPO. Notwithstanding the foregoing, for so long as the shares of Class B Common Stock are outstanding and have not been converted to shares of Class C Common Stock or to shares of Class D Common Stock pursuant to the Certificate of Incorporation, Sempra shall not be required under this Section 1.6 to amend or modify or to negotiate to amend or modify the provisions of Sections 10.1(a)(i), (ii), (iii), (iv), (vi), (xi), (xvi) or (xviii), 10.1(b), 10.2 and 10.3 of the Certificate of Incorporation.

ARTICLE II

TRANSFERS

Any Transfer or attempted Transfer of Equity Securities in violation of any provision of this Agreement shall be void.

(b) Notwithstanding anything to the contrary in this Agreement, no Stockholder shall Transfer any Equity Securities (whether or not such Transfer would otherwise be permitted by Section 2.1(a)) (i) to any Competitor of the Company or any of its Subsidiaries or (ii) if any such Transfer would constitute a Prohibited Transaction, unless, in any such case, such Transfer has been approved by Board Special Approval; provided, that any such Transfer of shares of Class B Common Stock shall be subject to the provisions of Section 5.3(c) of the Certificate of Incorporation.

(c) Notwithstanding anything to the contrary in this Agreement, no Stockholder shall Transfer any Equity Securities (whether or not the proposed Transferee is a Permitted Transferee or such Transfer would otherwise be permitted by Section 2.1(a)) to any Person without the consent of Stockholders holding in the aggregate a majority of the issued and outstanding shares of Class B Common Stock if such Transfer would result in a “Change of Control” within the meaning of clause (3) of the definition of Change of Control in the New Notes Indenture as modified by the second proviso contained in such definition (whether or not such Transfer is pursuant to a Mandatory Offer (as defined in the Certificate of Incorporation), the provisions of Section 2.3 or 2.4, or otherwise), unless such Transfer would, as a condition to the consummation thereof, result in, and such Transfer does result in, the Discharge of ISDA Obligations having occurred.

(d) It shall be a condition precedent to the Transfer of any Equity Securities to any Transferee (including any Permitted Transferee) after the date of this Agreement that

such Transferee (i) become a party to this Agreement by executing and delivering a joinder agreement hereto, substantially in the form attached as Annex A hereto, and, in the case of a Transfer of shares of Class A Common Stock, a joinder agreement to the Class A Voting Agreement and, in the case of a Transfer of shares of Class C Common Stock, a joinder agreement to the Class C Voting Agreement, (ii) except in the case of a Transfer of shares of Class B Common Stock, execute all such other agreements or documents as may reasonably be requested by the Company (which may include such representations and warranties made by the Transferee to the Company as may be reasonably requested by the Company to ensure compliance with applicable regulatory requirements, which representations and warranties shall be substantially in the form attached as Annex B hereto), (iii) in the case of a Transfer of shares of Class B Common Stock, execute all such other agreements or documents as may reasonably be requested by the Company for the sole purpose of ensuring compliance with the Securities Act and compliance with the terms this Agreement, and which are necessary for purposes of legal and/or regulatory compliance, (iv)ensure with the Transferring Stockholders that any merger control or other regulatory authorizations needed in connection with such Transfer are duly obtained and (v) deliver such agreements and documents to the Company at its address specified in Section 4.10. Such Person shall, upon satisfaction of such conditions to the reasonable satisfaction of the Company and its acquisition of Equity Securities, be a Stockholder for all purposes of this Agreement.

2.2 Additional Restrictions. No shares of Class C Common Stock held by any current or former employees of the Company or any of its Subsidiaries may be Transferred to any Person (except by will or in connection with customary estate planning) until the third anniversary of the Closing Date or as otherwise provided in the Management Incentive Plan. From and after the third anniversary of the Closing Date, any shares of Class C Common Stock acquired by any current or former employees of the Company or any of its Subsidiaries under the Management Incentive Plan may be Transferred only as provided in the Management Incentive Plan.

2.3 Tag-Along Rights.

(a) In the event of a proposed Transfer by one or more Stockholders (each, a “Transferring Stockholder”) of shares of Common Stock representing in the aggregate a majority of the issued and outstanding shares of all classes of Common Stock (calculated on a Fully Diluted Basis) (a “Tag-Along Transfer”) to a single Transferee or a Group of related Transferees, in any transaction or a series of related transactions (including, for the avoidance of doubt, where the conditions to a Tag-Along Transfer are satisfied as the result of a Mandatory Offer (as defined in the Certificate of Incorporation)), other than (x) to a Permitted Transferee or (y) in connection with a Public Offering or brokers’ transactions (within the meaning of Section 4(4) of the Securities Act) pursuant to Rule 144, each Stockholder other than the Transferring Stockholder (each, a “Tag-Along Participant”) shall have the right to participate on the same terms and conditions and for the same per share consideration as each Transferring Stockholder in the Transfer, in the manner set forth in this Section 2.3. Prior to any Tag-Along Transfer, following

compliance with Section 2.5 (if applicable), each Transferring Stockholder shall deliver to the Company prompt written notice (the “Transfer Notice”), which the Company will forward to each Tag-Along Participant within five (5) Business Days of receipt thereof, which notice shall state (i) the name of the proposed Transferee, (ii) the number of shares of Common Stock proposed to be Transferred by the Transferring Stockholder (the “Transferred Securities”), (iii) the proposed purchase price therefor, including a description of any non-cash consideration sufficiently detailed to permit the determination of the Fair Market Value thereof, and (iv) the other material terms and conditions of the proposed Tag-Along Transfer, including the proposed Tag-Along Transfer date (which date may not be less than 35 Business Days after delivery to the Tag-Along Participants of the Transfer Notice). Such notice shall be accompanied by a written offer from the proposed Transferee to purchase the Transferred Securities, which offer may be conditioned upon the consummation of the sale by each Transferring Stockholder, or the most recent drafts of the purchase and sale documentation between each Transferring Stockholder and the Transferee, which shall make provision for the participation of the Tag-Along Participants in such sale consistent with this Section 2.3.

(b) Each Tag-Along Participant may elect to participate in the proposed Tag-Along Transfer to the proposed Transferee identified in the Transfer Notice by giving written notice to the Company and to each Transferring Stockholder within twenty (20) Business Days after the delivery of the Transfer Notice to such Tag-Along Participant, which notice shall state that such Tag-Along Participant elects to exercise its rights of tag-along under this Section 2.3 and shall state the maximum number of shares of Common Stock sought to be Transferred. Each Tag-Along Participant shall be deemed to have waived its right of tag-along with respect to the Transferred Securities hereunder if it fails to give notice within the prescribed time period.

(c) At the closing of the Tag-Along Transfer of the Transferred Securities to the Transferee, each Tag-Along Participant exercising its tag-along rights hereunder shall deliver to the Transferring Stockholder certificates representing the Transferred Securities to be Transferred by such Tag-Along Participant, duly endorsed for transfer or accompanied by stock powers duly executed, in either case executed in blank or in favor of the applicable purchaser, against payment of the aggregate purchase price therefor by wire transfer of immediately available funds. Each Stockholder participating in a Tag-Along Transfer shall receive consideration in the same form and per share amount after deduction of such Stockholder’s proportionate share of the related expenses. Each Stockholder participating in a Tag-Along Transfer shall agree to make or agree to the same customary representations, covenants, indemnities and agreements as the Transferring Stockholder, so long as they are made severally and not jointly and the liabilities thereunder are borne on a pro rata basis based on the consideration to be received by each Stockholder; provided, that any general indemnity given by the Transferring Stockholder, applicable to liabilities not specific to the Transferring Stockholder, to the Transferee in connection with such Tag-Along Transfer shall be apportioned among the Stockholders participating in such Tag-Along Transfer according to the consideration received by each such Stockholder and shall not exceed 20% of such

Stockholder’s net proceeds from the Tag-Along Transfer; provided, further, that any representation relating specifically to a Stockholder or its ownership of the Equity Securities to be Transferred shall be made only by that Stockholder. The fees and expenses incurred in connection with a Tag-Along Transfer and for the benefit of all Stockholders (it being understood that costs incurred by or on behalf of a Stockholder for his, her or its sole benefit will not be considered to be for the benefit of all Stockholders), to the extent not paid or reimbursed by the Company or the Transferee or acquiring Person, shall be shared by all the Stockholders on a pro rata basis, based on the consideration received by each Stockholder in respect of its Equity Securities to be Transferred; provided that no Stockholder shall be obligated to make any out-of-pocket expenditure prior to the consummation of the Tag-Along Transfer (excluding de minimis expenditures). The proposed Tag-Along Transfer date may be extended beyond the date described in the Transfer Notice to the extent necessary to obtain required approvals of Governmental Entities and other required approvals and the Company shall use its commercially reasonable efforts to obtain, and the Stockholders shall use their respective commercially reasonable efforts to cooperate with the Company in obtaining, such approvals.

(d) If the Transferring Stockholder sells or otherwise Transfers to the Transferee any of its shares of Common Stock in breach of this Section 2.3, then each Tag-Along Participant shall have the right to sell to each Transferring Stockholder, and each Transferring Stockholder undertakes to purchase from each Tag-Along Participant, the number of shares of Common Stock that such Tag-Along Participant would have had the right to sell to the Transferee pursuant to this Section 2.3, for a per share amount and form of consideration and upon the terms and conditions on which the Transferee bought such shares from the Transferring Stockholder, but without any indemnity being granted by any Tag-Along Participant to the Transferring Stockholder; provided, however, that nothing contained in this Section 2.3(d) shall preclude any Stockholder from seeking alternative remedies against any such Transferring Stockholder as a result of its breach of this Section 2.3.

(e) In the event of a proposed Transfer of shares of Common Stock that is subject to this Section 2.3 and the provisions of Article XI of the Certificate of Incorporation, the provisions of Article XI of the Certificate of Incorporation shall apply first to such Transfer, and the provisions of this Section 2.3 shall apply second.

2.4 Drag-Along Rights.

(a) If one or more Stockholders holding in the aggregate (x) 75% of the issued and outstanding shares of Common Stock and (y) 70% of the issued and outstanding shares of Class B Common Stock determine to Transfer all of the issued and outstanding Equity Securities to any Person or Persons (other than a Stockholder Transferee and other than an Affiliate of any of the transferring Stockholders or a Group including one or more Affiliates of any of the transferring Stockholders) in any transaction or a series of related transactions that is proposed to be effected on an arms-length basis (a “Drag-Along

Transaction”), then, if requested by the Stockholders Transferring such Equity Securities (the “Section 2.4 Transferring Stockholders”), each other Stockholder (each, a “Selling Stockholder”) shall be required to sell to the proposed Transferee all of the Equity Securities held by it, for the same form and amount of consideration per share as the consideration per share to be received by the Section 2.4 Transferring Stockholders, and upon the same terms and conditions as those upon which the Section 2.4 Transferring Stockholders sell their Equity Securities to the proposed Transferee. If any holders of Equity Securities of any class are given an option as to the form and amount of consideration to be received in the Drag-Along Transaction, all holders of Equity Securities of such class must be given the same option. The Section 2.4 Transferring Stockholder(s) shall provide written notice (the “Drag-Along Notice”) to each other Selling Stockholder of any proposed Drag-Along Transaction as soon as practicable following its exercise of the rights provided in this Section 2.4(a). The Drag-Along Notice shall set forth the consideration to be paid by the proposed Transferee for the Equity Securities, the identity of the proposed Transferee and the material terms of the proposed Drag-Along Transaction.

(b) In connection with the Drag-Along Transaction, each Selling Stockholder will agree to make or agree to the same customary representations, covenants, indemnities and agreements as the Section 2.4 Transferring Stockholders, so long as they are made severally and not jointly and the liabilities thereunder are borne on a pro rata basis based on the consideration to be received by each Stockholder; provided, however, that (i) any general indemnity given by the Section 2.4 Transferring Stockholders, applicable to liabilities not specific to the Section 2.4 Transferring Stockholders, to the Transferee in connection with such Drag-Along Transaction shall be apportioned among the Selling Stockholders according to the consideration received by each Selling Stockholder and shall not exceed 20% of such Selling Stockholder’s net proceeds from the Drag-Along Transaction, (ii) that any representation relating specifically to a Selling Stockholder or its Equity Securities shall be made only by that Selling Stockholder and (iii) in no event shall any Stockholder be obligated to agree to any non-competition covenant or other similar agreement as a condition of participating in such Drag-Along Transaction. The fees and expenses incurred in connection with the Drag-Along Transaction and for the benefit of all Stockholders (it being understood that costs incurred by or on behalf of a Stockholder for his, her or its sole benefit will not be considered to be for the benefit of all Stockholders), to the extent not paid or reimbursed by the Company or the Transferee, shall be shared by all the Stockholders on a pro rata basis, based on the consideration received by each Stockholder in respect of its Equity Securities; provided, however, that no Stockholder shall be obligated to make any out-of-pocket expenditure prior to the consummation of the Drag-Along Transaction (excluding de minimis expenditures).

(c) Notwithstanding anything to the contrary in this Agreement, any Selling Stockholder whose assets (“Plan Assets”) constitute assets of one or more employee benefit plans and are subject to Part IV of Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), shall not be obligated to sell to any Person

to whom the sale of any Equity Securities would constitute a non-exempt “prohibited transaction” within the meaning of ERISA or the Code, provided, however, that if so requested by the Section 2.4 Transferring Stockholders: (i) such Selling Stockholder shall have taken commercially reasonable efforts to (x) structure its sale of Equity Securities so as not to constitute a non-exempt “prohibited transaction” or (y) obtain a ruling from the Department of Labor to the effect that such sale (as originally proposed or as restructured pursuant to clause (i)(x)) does not constitute a non-exempt “prohibited transaction” and (ii) such Selling Stockholder shall have delivered an opinion of counsel (which opinion and counsel are reasonably satisfactory to the Section 2.4 Transferring Stockholders) to the effect that such sale (as originally proposed or as restructured pursuant to clause (i)(x)) would constitute a non-exempt “prohibited transaction.”

(d) Upon the consummation of the Drag-Along Transaction and delivery by any Selling Stockholder of the duly endorsed certificate or certificates representing the Equity Securities held by such Selling Stockholder to be sold, together with a stock power duly executed in blank, the acquiring Person shall remit directly to such Selling Stockholder, by wire transfer of immediately available funds, the consideration for the Equity Securities sold pursuant thereto.

(e) In the event of a proposed Transfer of shares of Common Stock that is subject to this Section 2.4, Section 2.3 and the provisions of Article XI of the Certificate of Incorporation, the provisions of this Section 2.4 shall control.

2.5 Right of First Refusal.

(a) Subject to the terms and conditions specified in this Section 2.5 and without in an way limiting the restrictions on Transfer in this Article II, the Class A Stockholders and the Class B Stockholders (collectively, the “ROFR Stockholders”) shall have a right of first refusal if any Class C Stockholder (the “Initiator”) proposes to sell any shares of Class C Common Stock owned by it (the “Transfer Shares”), other than (i) to a Permitted Transferee or (ii) as a Tag-Along Participant pursuant to Section 2.3 or as a Selling Stockholder pursuant to Section 2.4.

(b) Each time the Initiator proposes so to sell any Transfer Shares, the Initiator shall give a written notice (the “Initiator Notice”) to each ROFR Stockholder, specifying the number of Transfer Shares and containing an irrevocable offer to sell the Transfer Securities to the ROFR Stockholders at the price, and upon the other material terms and conditions, specified in the Initiator Notice (the “Transfer Price”). The Transfer Price shall be equal to the price offered (the “Purchase Offer”) to the Initiator by a bona fide third party offeror (the “Third-Party Offeror”), the identity of which shall be specified in the Initiator Notice. If the Purchase Offer is contained in a written proposal, a copy of such written proposal shall be provided with the Initiator Notice.

(c) Within twenty (20) Business Days after its receipt of the Initiator Notice (the “ROFR Exercise Period”), each ROFR Stockholder who wishes to purchase any

Transfer Shares shall give a written notice to the Initiator (the “ROFR Notice”), specifying the number of Transfer Shares that such ROFR Stockholder wishes to purchase (up to such ROFR Stockholder’s Pro Rata Share) and, at the option of such ROFR Stockholder, indicating the maximum number of Transfer Shares that such ROFR Stockholder irrevocably commits to purchase in excess of such ROFR Stockholder’s Pro Rata Share (the “Excess Amount”). Any ROFR Notice shall upon delivery become binding on the ROFR Stockholder delivering such notice and shall become irrevocable without the necessity of any acceptance thereof by the Initiator. If one or more ROFR Stockholders decline to participate in such purchase or elect to purchase less than such ROFR Stockholder’s Pro Rata Share, then the remaining Transfer Shares shall automatically be deemed to be accepted by the ROFR Stockholders who specified an Excess Amount in their respective notice of acceptance, and shall be allocated among such ROFR Stockholders (with rounding to avoid fractional shares) in proportion to their respective Pro Rata Share, but in no event shall an amount greater than a ROFR Stockholder’s Excess Amount be allocated to such ROFR Stockholder. Any excess Transfer Securities remaining after such allocation shall be further allocated among the remaining ROFR Stockholders whose specified Excess Amount has not been satisfied (with rounding to avoid fractional shares) in proportion to each ROFR Stockholder’s respective Pro Rata Share, and such procedure shall be employed until the entire Excess Amount of each ROFR Stockholder has been satisfied or until all of the Transfer Securities have been allocated. Two or more ROFR Stockholders may also deliver a joint ROFR Notice. A ROFR Stockholder’s failure to give timely written notice regarding its election to purchase any Transfer Securities pursuant to this Section 2.5 shall be deemed an election by such ROFR Stockholder not to purchase any Transfer Securities. For purposes of this Section 2.5, the term “Pro Rata Share” means, with respect to any ROFR Stockholder, with respect to any proposed Transfer, on the applicable Transfer date, a percentage of the Transfer Shares being offered to the ROFR Stockholders equal to a fraction determined by dividing (x) the number of shares of Common Stock held by such ROFR Stockholder as of such date by (y) the total number of shares of Common Stock held as of such date by all ROFR Stockholders participating in the allocation round for which Pro Rata Shares are being calculated.

(d) Upon the consummation of the purchase by the ROFR Stockholders of the Transfer Shares pursuant to this Section 2.5 and delivery by the Initiator of the duly endorsed certificate or certificates representing the Transfer Shares, together with a stock power duly executed in blank, each of the ROFR Stockholders who has purchased such Transfer Shares shall remit directly to the Initiator, by wire transfer of immediately available funds, the consideration for the Equity Securities sold pursuant thereto.

(e) Anything in this Section 2.5 to the contrary notwithstanding, if the ROFR Stockholders do not deliver ROFR Notices covering in the aggregate all of the Transfer Shares proposed to be sold by the Initiator in its Initiator Notice, then no ROFR Stockholder shall be entitled to purchase any of such Transfer Shares pursuant to this Section 2.5. If, at the end of the ROFR Exercise Period, none of the ROFR Stockholders has delivered to the Initiator an effective ROFR Notice, or if the ROFR Stockholders

have delivered ROFR Notices covering in the aggregate less than all of the Transfer Shares, then the Initiator shall have sixty (60) Business Days after the expiration of the ROFR Exercise Period during which to Transfer all (but not less than all) of the Transfer Shares to the Third-Party Offeror, at a price not lower than the Transfer Price and on terms no more favorable to the Third-Party Offeror in all material respects than those contained in the Transfer Notice. If, at the end of such sixty-Business Day period, the Initiator has not completed the Transfer of the Transfer Shares to the Third-Party Offeror, the Initiator shall no longer be permitted to Transfer the Transfer Shares to the Third-Party Offeror or any other Person without again complying with the requirements of this Section 2.5; provided, however, that if the Initiator determines at any time within such sixty-Business Day period that the Transfer of the Transfer Shares to the Third-Party Offeror at a price not lower than the Transfer Price and on terms no more favorable to the Third-Party Offeror in all material respects than those contained in the Transfer Notice is impractical, the Initiator may terminate all attempts to Transfer the Transfer Shares and recommence the procedures described in this Section 2.5 prior to the expiration of such sixty-Business Day period by delivering a written notice thereof to each ROFR Stockholder.

2.6 Legend.

(a) All certificates representing the Equity Securities held by each Stockholder shall bear legends substantially in the following forms:

(b) Upon the permitted sale of any Equity Securities pursuant to (i) an effective registration statement under the Securities Act or pursuant to Rule 144 or (ii) another exemption from registration under the Securities Act or upon the termination of this Agreement, the certificates representing such Equity Securities shall be replaced, at the expense of the Company, with certificates or instruments not bearing the legends required by Section 2.6(a); provided, however, that the Company may condition such replacement of certificates under clause (ii) upon the receipt of an opinion of securities counsel reasonably satisfactory to the Company.

The arbitration tribunal shall not consolidate such arbitrations unless it determines that (i) there are issues of fact or law common to the various arbitrations so that a consolidated proceeding would be more efficient than separate proceedings and (ii) no party would be prejudiced as a result of such consolidation through undue delay or otherwise. In the event of different rulings on this question by the arbitration tribunal constituted hereunder and the tribunal constituted under any other Related Agreement, the ruling of the arbitration tribunal governing the first proceeding to have been filed shall control. In the event of the consolidation of one or more proceedings pursuant to this subsection, the arbitration tribunal governing the first such proceeding to have been filed shall govern the consolidated proceeding unless otherwise agreed by all parties to the proceedings being consolidated. Solely for purposes of this subsection (c), (i) a proceeding shall be deemed to have been filed when the related demand for arbitration is served by the complaining party and (ii) in the event that two proceedings shall have been filed on the same day, the proceeding involving the largest dollar amount in dispute shall be deemed to have been the first filed.

(d) The arbitration award shall be final and binding on the parties. Judgment upon the award may be entered by any court having jurisdiction thereof or having jurisdiction over the relevant party or its assets.

4.16 Waiver of Certain Damages. NO PARTY SHALL BE ENTITLED TO ANY RECOVERY UNDER THIS AGREEMENT FOR CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY OR INDIRECT DAMAGES, LOST PROFITS OR OTHER BUSINESS INTERRUPTION DAMAGES. THIS SECTION 4.16 SHALL SURVIVE THE TERMINATION OF THIS AGREEMENT AND ALL TRANSACTIONS CONTEMPLATED HEREBY.

4.17 Counterparts; Facsimile Signatures. This Agreement may be executed in any number of counterparts, each of which shall be an original, but all of which together shall constitute one instrument. This Agreement may be executed by facsimile signature(s) or in pdf file.
