Except as otherwise expressly provided in this Certificate of Incorporation, shares of Class A Common Stock, Class B Common Stock, Class C Common Stock and Class D Common Stock shall have the same rights and privileges and shall rank equally, share ratably and be identical in all respects and as to all matters. No shares of Class D Common Stock shall be issued or outstanding prior to the conversion of issued and outstanding shares of Class A Common Stock, Class B Common Stock, if applicable, and Class C Common Stock into shares of Class D Common Stock upon the occurrence of an IPO pursuant to Section 5.6.

Section 4.3 Issuance of Additional Shares. The Board is hereby authorized to cause the Corporation from time to time to issue additional shares of Common Stock (but, in the case of shares of Class A Common Stock, Class B Common Stock and Class C Common Stock, only to the extent of shares of such classes authorized under Section 4.1 and unissued, unless and to the extent Section 4.1 is amended as provided herein) to Holders of shares of Common Stock or other Persons, as shall be determined by the Board; provided, that (x) any issuance of additional shares of Common Stock pursuant to this Section 4.3 shall be approved by the Board as set forth in Section 10.1 and (y) for so long as Sempra holds shares of Class B Common Stock, any further issuances of Class B Common Stock may be made only to Sempra.

Section 4.4 Preemptive Rights.

(a) The Corporation shall not issue or sell, agree to issue or sell, or reserve or set aside for issuance or sale, to any Person any Equity Securities of the Corporation (other than any Exempt Securities or Equity Securities issued in connection with an IPO) (“Preemptive Securities”) unless the Corporation shall have first offered to sell to each Holder of shares of Common Stock (each, a “Preemptive Right Holder”) such Preemptive Right Holder’s Pro Rata Share of such Preemptive Securities, in accordance with the provisions of this Section 4.4.

(b) The Corporation shall give to each Preemptive Right Holder a written notice of its intention to issue or sell any Preemptive Securities (the “Preemptive Offer”), describing the material terms of such Preemptive Securities and specifying the price and other material terms upon which the Preemptive Securities are proposed to be issued or sold, including the anticipated date of such issuance or sale. The Preemptive Offer shall remain open and irrevocable for a period of at least twenty (20) Business Days from the date it is delivered by the Corporation (the “Preemptive Offer Period”). Each Preemptive Right Holder may elect to purchase all or any portion of its Pro Rata Share of the Preemptive Securities, at the price and upon the terms specified in the Preemptive Offer, by delivering to the Corporation, as soon as practical after the receipt of the Preemptive Offer but in any event within the Preemptive Offer Period, a written notice of such election (the “Purchase Notice”) specifying the quantity of Preemptive Securities that such Preemptive Right Holder wishes to purchase. The Purchase Notice shall constitute an irrevocable agreement of such Preemptive Right Holder to purchase the quantity of Preemptive Securities specified in the Purchase Notice. Any purchase of Preemptive Securities by any Preemptive Right Holder shall be consummated on the closing date specified in the Preemptive Offer (or, if other Persons are also purchasing such Preemptive Securities, the date on which such Preemptive Securities described in the applicable Preemptive Offer are first issued and sold to such other Persons). In the event

that Preemptive Securities are being issued or will be issuable as part of an investment unit with other securities of the Corporation, the right of Preemptive Right Holders to purchase such Preemptive Securities shall be a right to purchase the entire investment unit.

(c) The Corporation shall have ninety (90) calendar days from the expiration of the Preemptive Offer Period to consummate the proposed issuance or sale of the Preemptive Securities that are not being purchased by the Preemptive Right Holders, at a price and upon other terms and conditions that are as favorable to the Corporation in all material respects as those specified in the Preemptive Offer. If the Corporation proposes to issue Preemptive Securities after such 90-calendar day period or at a price or upon terms that are not as favorable to the Corporation in all material respects as those specified in the Preemptive Offer, the Corporation must again comply with the provisions of this Section 4.4.

(d) For purposes of this Section 4.4, the “Pro Rata Share” of a Preemptive Right Holder shall be a fraction, (x) the numerator of which shall be the total number of shares of Common Stock held by such Preemptive Right Holder and (y) the denominator of which shall be the total number of shares of Common Stock held by all Preemptive Right Holders (including such Preemptive Right Holder), in the case of both clauses (x) and (y) on a Fully Diluted Basis, as of the date of determination.

(e) Subject to Section 10.2(d), the preemptive rights of Holders of shares of Common Stock under this Section 4.4 may be waived by the affirmative vote of both (i) Holders of at least 75% of the issued and outstanding shares of Common Stock, voting as a single class, and (ii) Holders of at least a majority of the issued and outstanding shares of Class B Common Stock.

Section 4.5 Redemption. If any holder of shares of Class A Common Stock or any holder of shares of Class C Common Stock who is not a party to the Stockholder Agreement (each, a “Non-Selling Holder”) fails for any reason to sell the Equity Securities held by such Non-Selling Holder to the purchaser in any Drag-Along Transaction (as defined in the Stockholders Agreement) with respect to which a written notice has been properly given to such Non-Selling Holder in accordance with Section 2.4(a) of the Stockholders Agreement, the Corporation shall have the right (but not the obligation) to purchase all (but not less than all) of the Equity Securities held by such Non-Selling Holder for the same form and amount of consideration per share as the consideration per share to be received by the Section 2.4 Transferring Stockholder(s) (as defined in the Stockholders Agreement) in such Drag-Along Transaction. The right to purchase the Equity Securities held by any Non-Selling Holder pursuant to this Section

4.5 shall be exercised by the Corporation by giving a written notice to such Non-Selling Holder, which shall specify the consideration to be paid by the Corporation to such Non-Selling Holder for the Equity Securities to be purchased by the Corporation and the intended closing date of such purchase, and the purchase of the Equity Securities pursuant to this Section 4.5 shall be consummated on the closing date specified in such written notice.

LIMITATION OF LIABILITY; INDEMNIFICATION

Section 8.1 Liability of Directors. No director of the Corporation shall be liable to the Corporation or its stockholders for monetary damages for breach of his or her fiduciary duty as a director, provided that nothing contained in this Certificate of Incorporation shall eliminate or limit the liability of a director (a) for any breach of the director’s duty of loyalty to the Corporation or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law, (c) under Section 174 of the DGCL or (d) for any transaction from which the director derived an improper personal benefit. If the DGCL is amended after the filing of this Certificate of Incorporation to authorize corporate action further eliminating or

limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended. Any repeal or modification of this Section 8.1 by the stockholders of the Corporation shall not adversely affect any right or protection of a director of the Corporation existing in respect of any act or omission occurring prior to the time of such repeal or modification.

Section 8.2 Indemnification of Directors and Officers.

(a) The Corporation shall indemnify and hold harmless to the fullest extent authorized by the DGCL as the same exists or may hereafter be amended (but in the case of any such amendment only to the extent that such amendment permits the Corporation to provide broader indemnification rights than the DGCL permitted the Corporation to provide prior to such amendment) any Person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Corporation) by reason of the fact that such Person is or was a director or officer of the Corporation, or is or was serving at the request of the Corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit or proceeding if such Person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the Person did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful.

(b) The Corporation shall indemnify and hold harmless to the fullest extent authorized by the DGCL as the same exists or may hereafter be amended (but in the case of any such amendment only to the extent that such amendment permits the Corporation to provide broader indemnification rights than the DGCL permitted the Corporation to provide prior to such amendment) any Person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that such Person is or was a director or officer of the Corporation, or is or was serving at the request of the Corporation as a director or officer of another corporation, partnership, joint venture,

trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection with the defense or settlement of such action or suit, if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Corporation and except that no such indemnification shall be made in respect of any claim, issue or matter as to which such Person shall have been adjudged to be liable to the Corporation unless and only to the extent that the Court of Chancery of the State of Delaware or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such Person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.
