Section 5.5 Indemnification. (a) The Corporation shall have the power, to the maximum extent permitted by Maryland law in effect from time to time, to obligate itself to indemnify, and to pay or reimburse reasonable expenses in advance of final disposition of a proceeding to, (i) any individual who is a present or former director or officer of the Corporation or (ii) any individual who, while a director or officer of the Corporation and at the request of the Corporation, serves or has served as a director, officer, partner, member, manager or trustee of another corporation, real estate investment trust, partnership, limited liability company, joint venture, trust, employee benefit plan or any other enterprise from and against any claim or liability to which such person may become subject or which such person may incur by reason of

Section 5.7 REIT Qualification. The Board of Directors shall use its reasonable best efforts to take such actions as are necessary or appropriate to preserve the status of the Corporation as a REIT; however, if the Board of Directors determines that it is no longer in the best interests of the Corporation to attempt to, or continue to, qualify as a REIT, the Board of Directors may revoke or otherwise terminate the Corporation’s REIT election pursuant to Section 856(g) of the Code. The Board of Directors, in its sole and absolute discretion, also may (a) determine upon advice of counsel that compliance with any restriction or limitation on stock ownership and transfers set forth in Article VII is no longer required for REIT qualification and (b) make any other determination or take any other action pursuant to Article VII.

Subject to Section 5.9(b), in the event that any Identified Person acquires knowledge of a Business Opportunity, such Identified Person shall have no obligation to communicate or offer such Business Opportunity to the Corporation and, to the fullest extent permitted by law, shall not be liable to the Corporation or its stockholders by reason of the fact that such Identified Person pursues or acquires such Business Opportunity.

(b) The Corporation does not renounce its interest in any Business Opportunity offered to any Identified Person if such opportunity is expressly offered to such Identified Person in his or her capacity as a director or officer of the Corporation. For the avoidance of doubt, a Business Opportunity shall not be deemed to include any business opportunity that the Corporation is not financially able or contractually permitted or legally able to undertake, or that is, from its nature, not in the line of the Corporation’s business or is of no practical advantage to it or that is one in which the Corporation has no interest or reasonable expectancy to have any interest.

(c) Any action taken by a director or officer pursuant to this Section 5.9 shall not constitute an act or omission committed in bad faith or as the result of active or deliberate dishonesty, and any benefit received, directly or indirectly, by such director or officer as the result of taking such action shall not constitute receipt of an improper benefit or profit in money, property, services or otherwise.

The Board of Directors, with the approval of a majority of the entire Board of Directors and without any action by the stockholders of the Corporation, may amend the Charter from time to time to increase or decrease the aggregate number of shares of stock or the number of shares of stock of any class or series that the Corporation has authority to issue.

Section 6.2 Common Stock. Subject to the provisions of Article VII and except as may otherwise be specified in the Charter, each share of Common Stock shall entitle the holder thereof to one vote.

Section 6.3 Preferred Stock. The Board of Directors may classify any unissued shares of Preferred Stock and reclassify any previously classified but unissued shares of Preferred Stock (including, without limitation, any shares that were previously issued but which have been acquired by the Corporation) from time to time into shares of any one or more classes or series of stock.

Any of the terms of any class or series of stock set or changed pursuant to clause (c) of this Section 6.4 may be made dependent upon facts or events ascertainable outside the Charter (including determinations by the Board of Directors or other facts or events within the control of the

6

Corporation) and may vary among holders thereof, provided that the manner in which such facts, events or variations shall operate upon the terms of such class or series of stock is clearly and expressly set forth in the articles supplementary or other Charter document.

Section 6.5 Charter and Bylaws. The rights of all stockholders and the terms of all stock are subject to the provisions of the Charter and the Bylaws.

Section 6.6 Transferable Shares; Preferential Dividends. Notwithstanding any other provision in the Charter, if the Corporation elects to continue to qualify for U.S. federal income tax purposes as a REIT, then until such time as the Board of Directors determines that it is no longer in the best interests of the Corporation to attempt to, or continue to, qualify as a REIT, no determination shall be made by the Board of Directors nor shall any transaction be entered into by the Corporation that would cause any shares in the Corporation not to constitute “transferable shares” under Section 856(a)(2) of the Code or that would cause any distribution to constitute a preferential dividend as described in Section 562(c) of the Code.

Section 6.7 Stockholders’ Consent in Lieu of Meeting. Any action required or permitted to be taken at any meeting of the holders of Common Stock entitled to vote generally in the election of directors may be taken without a meeting by consent, in writing or by electronic transmission, in any manner and by any vote permitted by the MGCL and set forth in the Bylaws.

Section 6.8 Distributions. The Board of Directors from time to time may authorize the Corporation to declare and pay to stockholders such dividends or other distributions in cash or other assets of the Corporation or in securities of the Corporation, including in shares of one class or series of the Corporation’s stock payable to holders of shares of another class or series of stock of the Corporation, or in any other form as the Board of Directors in its sole and absolute discretion shall determine.

(a) Basic Restrictions.

(i) (1) No Person, other than an Excepted Holder, shall Beneficially Own or Constructively Own shares of Capital Stock in excess of the Aggregate Stock Ownership Limit, (2) no Person, other than an Excepted Holder, shall Beneficially Own or Constructively Own shares of Common Stock in excess of the Common Stock Ownership Limit and (3) no Excepted Holder shall Beneficially Own or Constructively Own shares of Capital Stock in excess of the Excepted Holder Limit for such Excepted Holder.

(ii) No Person shall Beneficially Own or Constructively Own shares of Capital Stock to the extent that such Beneficial Ownership or Constructive Ownership of Capital Stock would result in the Corporation being “closely held” within the meaning of Section 856(h) of the Code (without regard to whether the ownership interest is held during the last half of a taxable year), or otherwise failing to qualify as a REIT (including, without limitation, Beneficial Ownership or Constructive Ownership that would result in the Corporation actually owning or Constructively Owning an interest in a tenant that is described in Section 856(d)(2)(B) of the Code if the income derived by the Corporation from such tenant, taking into account any other income of the Corporation that would not qualify under the gross income requirements of Section 856(c) of the Code, would cause the Corporation to fail to satisfy any of such gross income requirements).

(iii) No Person shall own shares of Capital Stock to the extent that such ownership of Capital Stock would, at any time prior to January 1, 2020, result in 50 percent (50%) or more in value of the outstanding Capital Stock of the Corporation being owned, directly or indirectly, by Persons who owned, at any time, directly or indirectly, 50 percent (50%) or more in value of the outstanding shares of InfraREIT, L.L.C.

(iv) Any Transfer of shares of Capital Stock that, if effective, would result in the Capital Stock being beneficially owned by less than 100 Persons (determined under the principles of Section 856(a)(5) of the Code) shall be void ab initio, and the intended transferee shall acquire no rights in such shares of Capital Stock.

10

(b) Transfer in Trust. If any Transfer of shares of Capital Stock occurs which, if effective, would result in any Person Beneficially Owning or Constructively Owning shares of Capital Stock in violation of Section 7.2.1(a)(i), (ii) or (iii),

(i) then that number of shares of the Capital Stock the Beneficial or Constructive Ownership of which otherwise would cause such Person to violate Section 7.2.1(a)(i), (ii) or (iii) (rounded up to the nearest whole share) shall be automatically transferred to a Trust for the benefit of a Charitable Beneficiary, as described in Section 7.3, effective as of the close of business on the Business Day prior to the date of such Transfer, and such Person shall acquire no rights in such shares; or

(ii) if the transfer to the Trust described in Section 7.2(b)(i) would not be effective for any reason to prevent the violation of Section 7.2.1(a)(i), (ii) or (iii), then the Transfer of that number of shares of Capital Stock that otherwise would cause any Person to violate Section 7.2.1(a)(i), (ii) or (iii) shall be void ab initio, and the intended transferee shall acquire no rights in such shares of Capital Stock.

To the extent that, upon a transfer of shares of Capital Stock pursuant to this Section 7.2.1(b), a violation of any provision of this Article VII would nonetheless be continuing (for example where the ownership of shares of Capital Stock by a single Trust would violate the 100 stockholder requirement applicable to REITs), then shares of Capital Stock shall be transferred to that number of Trusts, each having a distinct Trustee and a Charitable Beneficiary or Beneficiaries that are distinct from those of each other Trust, such that there is no violation of any provision of this Article VII.

Section 7.2.2 Remedies for Breach. If the Board of Directors shall at any time determine that a Transfer or other event has taken place that results in a violation of Section 7.2.1 or that a Person intends to acquire or has attempted to acquire Beneficial Ownership or Constructive Ownership of any shares of Capital Stock in violation of Section 7.2.1 (whether or not such violation is intended), the Board of Directors shall take such action as it deems advisable to refuse to give effect to or to prevent such Transfer or other event, including, without limitation, causing the Corporation to redeem shares, refusing to give effect to such Transfer on the books of the Corporation or instituting proceedings to enjoin such Transfer or other event; provided, however, that any Transfer or attempted Transfer or other event in violation of Section 7.2.1 shall automatically result in the transfer to the Trust described above, and, where applicable, such Transfer (or other event) shall be void ab initio as provided above irrespective of any action (or non-action) by the Board of Directors.

Section 7.2.3 Notice of Restricted Transfer. Any Person who acquires or attempts or intends to acquire Beneficial Ownership or Constructive Ownership of shares of Capital Stock that will or may violate Section 7.2.1(a) or any Person who would have owned shares of Capital Stock that resulted in a transfer to the Trust pursuant to the provisions of Section 7.2.1(b) shall immediately give written notice to the Corporation of such event or, in the case of such a proposed or attempted transaction, give at least 15 days prior written notice, and shall provide to the Corporation such other information as the Corporation may request in order to determine the effect, if any, of such Transfer on the Corporation’s status as a REIT.

11

Section 7.2.4 Owners Required To Provide Information. From the Initial Date and prior to the Restriction Termination Date:

(a) every owner of five percent or more (or such lower percentage as required by the Code or the Treasury Regulations promulgated thereunder) of the outstanding shares of Capital Stock, within 30 days after the end of each taxable year, shall give written notice to the Corporation stating the name and address of such owner, the number of shares of Capital Stock Beneficially Owned and a description of the manner in which such shares are held. Each such owner shall provide to the Corporation such additional information as the Corporation may request in order to determine the effect, if any, of such Beneficial Ownership on the Corporation’s status as a REIT and to ensure compliance with the Aggregate Stock Ownership Limit and the Common Stock Ownership Limit; and

(b) each Person who is a Beneficial Owner or Constructive Owner of Capital Stock and each Person (including the stockholder of record) who is holding Capital Stock for a Beneficial Owner or Constructive Owner shall provide to the Corporation such information as the Corporation may request, in order to determine the Corporation’s status as a REIT and to comply with requirements of any taxing authority or governmental authority or to determine such compliance.

Section 7.2.5 Remedies Not Limited. Subject to Section 5.7 of the Charter, nothing contained in this Section 7.2 shall limit the authority of the Board of Directors to take such other action as it deems necessary or advisable to protect the Corporation in preserving the Corporation’s status as a REIT.

Section 7.2.6 Ambiguity. In the case of an ambiguity in the application of any of the provisions of this Section 7.2, Section 7.3, or any definition contained in Section 7.1, the Board of Directors shall have the power to determine the application of the provisions of this Section 7.2 or Section 7.3 or any such definition with respect to any situation based on the facts known to it. In the event Section 7.2 or 7.3 requires an action by the Board of Directors and the Charter fails to provide specific guidance with respect to such action, the Board of Directors shall have the power to determine the action to be taken so long as such action is not contrary to the provisions of Sections 7.1, 7.2 or 7.3. Absent a decision to the contrary by the Board of Directors, if a Person would have (but for the remedies set forth in Section 7.2.2) acquired Beneficial Ownership or Constructive Ownership of Stock in violation of Section 7.2.1, such remedies (as applicable) shall apply first to the shares of Stock which, but for such remedies, would have been Beneficially Owned or Constructively Owned (but not actually owned) by such Person, pro rata among the Persons who actually own such shares of Stock based upon the relative number of the shares of Stock held by each such Person.

Section 7.2.7 Exceptions.

(a) Subject to Section 7.2.1(a)(ii), the Board of Directors, subject to the directors’ duties under applicable law, may exempt (prospectively or retroactively) a Person from the Aggregate Stock Ownership Limit and the Common Stock Ownership Limit, as the case may be, and may establish or increase an Excepted Holder Limit for such Person if:

(i) the Board of Directors obtains such representations and undertakings from such Person as are reasonably necessary to ascertain that no Individual’s Beneficial Ownership or Constructive Ownership of such shares of Capital Stock will violate Section 7.2.1(a)(ii);

12

(ii) such Person does not and represents that it will not actually own or Constructively Own an interest in a tenant of the Corporation (or a tenant of any entity owned or controlled by the Corporation) that would cause the Corporation to actually own or Constructively Own more than a 9.9% interest (as set forth in Section 856(d)(2)(B) of the Code) in such tenant and the Board of Directors obtains such representations and undertakings from such Person as the Board of Directors determines, in its sole and absolute discretion, are reasonably necessary to ascertain this fact (for this purpose, a tenant from whom the Corporation (or an entity owned or controlled by the Corporation) derives (and is expected to continue to derive) a sufficiently small amount of revenue such that, in the judgment of the Board, rent from such tenant would not adversely affect the Corporation’s ability to qualify as a REIT shall not be treated as a tenant of the Corporation); and

(iii) such Person agrees that any violation or attempted violation of such representations or undertakings (or other action which is contrary to the restrictions contained in Sections 7.2.1 through 7.2.6) will result in such shares of Capital Stock being automatically transferred to a Trust in accordance with Sections 7.2.1(b) and 7.3.

(b) Prior to granting any exception pursuant to Section 7.2.7(a), the Board of Directors may require a ruling from the Internal Revenue Service, or an opinion of counsel, in either case in form and substance satisfactory to the Board of Directors, as it may deem necessary or advisable in order to determine or ensure the Corporation’s status as a REIT. Notwithstanding the receipt of any ruling or opinion, the Board of Directors may impose such conditions or restrictions as it deems appropriate in connection with granting such exception.

(c) Subject to Section 7.2.1(a)(ii), an underwriter which participates in a public offering or a private placement of Capital Stock (or securities convertible into or exchangeable for Capital Stock) may Beneficially Own or Constructively Own shares of Capital Stock (or securities convertible into or exchangeable for Capital Stock) in excess of the Aggregate Stock Ownership Limit, the Common Stock Ownership Limit, or both such limits, but only to the extent necessary to facilitate such public offering or private placement.

(d) The Board of Directors may only reduce the Excepted Holder Limit for an Excepted Holder: (1) with the written consent of such Excepted Holder at any time, or (2) pursuant to the terms and conditions of the agreements and undertakings entered into with

13

such Excepted Holder in connection with the establishment of the Excepted Holder Limit for that Excepted Holder. No Excepted Holder Limit shall be reduced to a percentage that is less than the Common Stock Ownership Limit or the Aggregate Stock Ownership Limit, as applicable.

Section 7.2.8 Increase or Decrease in Common Stock Ownership or Aggregate Stock Ownership Limits. Subject to Section 7.2.1 (a)(ii), the Board of Directors may from time to time increase the Common Stock Ownership Limit and the Aggregate Stock Ownership Limit for one or more Persons and decrease the Common Stock Ownership Limit and the Aggregate Stock Ownership Limit for all other Persons; provided, however, that the decreased Common Stock Ownership Limit or Aggregate Stock Ownership Limit will not be effective for any Person that Beneficially Owns or Constructively Owns shares of Capital Stock in excess of such decreased Common Stock Ownership Limit or Aggregate Stock Ownership Limit until such time as such Person’s Beneficial Ownership or Constructive Ownership of shares of Capital Stock, as applicable, equals or falls below the decreased Common Stock Ownership Limit and/or Aggregate Stock Ownership Limit, but any further acquisition of shares of Capital Stock by such Person will be in violation of the Common Stock Ownership Limit or Aggregate Stock Ownership Limit. Notwithstanding the foregoing, any new Common Stock Ownership Limit and/or Aggregate Stock Ownership Limit shall not allow five or fewer Persons to Beneficially Own more than 49.9% in value of the outstanding Capital Stock.

Section 7.2.9 Legend. Each certificate for shares of Capital Stock shall bear substantially the following legend:

The shares represented by this certificate are subject to restrictions on Beneficial and Constructive Ownership and Transfer for the purpose, among others, of the Corporation’s maintenance of its status as a Real Estate Investment Trust under the Internal Revenue Code of 1986, as amended (the “Code”). Subject to certain further restrictions and except as expressly provided in the Corporation’s Charter, (i) no Person may Beneficially or Constructively Own shares of the Corporation’s Common Stock in excess of the Common Stock Ownership Limit unless such Person is an Excepted Holder (in which case the Excepted Holder Limit shall be applicable); (ii) no Person may Beneficially or Constructively Own shares of Capital Stock of the Corporation in excess of the Aggregate Stock Ownership Limit, unless such Person is an Excepted Holder (in which case the Excepted Holder Limit shall be applicable); (iii) no Person may Beneficially or Constructively Own Capital Stock that would result in the Corporation being “closely held” under Section 856(h) of the Code or otherwise cause the Corporation to fail to qualify as a REIT; (iv) no Person may own shares of Capital Stock of the Corporation to the extent that such ownership of Capital Stock would, at any time prior to January 1, 2020, result in 50 percent (50%) or more in value of the outstanding Capital Stock of the Corporation being owned, directly or indirectly, by Persons who owned, at any time, directly or indirectly, 50 percent (50%) or more in value of the outstanding shares of InfraREIT, L.L.C.; and (v) no Person may Transfer shares of Capital Stock if such Transfer would result in the Capital Stock of the Corporation being owned by fewer than 100 Persons. Any Person who Beneficially or Constructively Owns or attempts to Beneficially or Constructively Own shares of Capital Stock which causes or will cause a Person to Beneficially

14

or Constructively Own shares of Capital Stock in excess or in violation of the above limitations must immediately notify the Corporation. If any of the restrictions on transfer or ownership are violated, the shares of Capital Stock represented hereby will be automatically transferred to a Trustee of a Trust for the benefit of one or more Charitable Beneficiaries. In addition, the Corporation may redeem shares upon the terms and conditions specified by the Board of Directors in its sole and absolute discretion if the Board of Directors determines that ownership or a Transfer or other event may violate the restrictions described above. Furthermore, upon the occurrence of certain events, attempted Transfers in violation of the restrictions described above may be void ab initio. All capitalized terms in this legend have the meanings defined in the Charter of the Corporation, as the same may be amended from time to time, a copy of which, including the restrictions on transfer and ownership, will be furnished to each holder of Capital Stock of the Corporation on request and without charge. Requests for such a copy may be directed to the Secretary of the Corporation at its Principal Office.

Instead of the foregoing legend, the certificate may state that the Corporation will furnish a full statement about certain restrictions on transferability to a stockholder on request and without charge.

Section 7.3 Transfer of Capital Stock in Trust.

Section 7.3.1 Ownership in Trust. Upon any purported Transfer or other event described in Section 7.2.1(b) that would result in a transfer of shares of Capital Stock to a Trust, such shares of Capital Stock shall be deemed to have been transferred to the Trustee as trustee of a Trust for the exclusive benefit of one or more Charitable Beneficiaries. Such transfer to the Trustee shall be deemed to be effective as of the close of business on the Business Day prior to the purported Transfer or other event that results in the transfer to the Trust pursuant to Section 7.2.1(b). The Trustee shall be appointed by the Corporation and shall be a Person unaffiliated with the Corporation and any Prohibited Owner. Each Charitable Beneficiary shall be designated by the Corporation as provided in Section 7.3.6.

Section 7.3.2 Status of Shares Held by the Trustee. Shares of Capital Stock held by the Trustee shall be issued and outstanding shares of Capital Stock of the Corporation. The Prohibited Owner shall have no rights in the shares held by the Trustee. The Prohibited Owner shall not benefit economically from ownership of any shares held in trust by the Trustee, shall have no rights to dividends or other distributions and shall not possess any rights to vote or other rights attributable to the shares held in the Trust.

Section 7.3.3 Dividends and Voting Rights. The Trustee shall have all voting rights and rights to dividends or other distributions with respect to shares of Capital Stock held in the Trust, which rights shall be exercised for the exclusive benefit of the Charitable Beneficiary. Any dividend or other distribution paid prior to the discovery by the Corporation that the shares

15

of Capital Stock have been transferred to the Trustee shall be paid by the recipient of such dividend or distribution to the Trustee upon demand and any dividend or other distribution authorized but unpaid shall be paid when due to the Trustee. Any dividend or other distribution so paid to the Trustee shall be held in trust for the Charitable Beneficiary. The Prohibited Owner shall have no voting rights with respect to shares held in the Trust and, subject to Maryland law, effective as of the date that the shares of Capital Stock have been transferred to the Trustee, the Trustee shall have the authority (at the Trustee’s sole and absolute discretion) (i) to rescind as void any vote cast by a Prohibited Owner prior to the discovery by the Corporation that the shares of Capital Stock have been transferred to the Trustee and (ii) to recast such vote; provided, however, that if the Corporation has already taken irreversible corporate action, then the Trustee shall not have the authority to rescind and recast such vote. Notwithstanding the provisions of this Article VII, until the Corporation has received notification that shares of Capital Stock have been transferred into a Trust, the Corporation shall be entitled to rely on its share transfer and other stockholder records for purposes of preparing lists of stockholders entitled to vote at meetings, determining the validity and authority of proxies and otherwise conducting votes and determining the other rights of stockholders.

Section 7.3.4 Sale of Shares by Trustee. Within 20 days of receiving notice from the Corporation that shares of Capital Stock have been transferred to the Trust, the Trustee of the Trust shall sell the shares held in the Trust to a Person, designated by the Trustee, whose ownership of the shares will not violate the ownership limitations set forth in Section 7.2.1(a). Upon such sale, the interest of the Charitable Beneficiary in the shares sold shall terminate and the Trustee shall distribute the net proceeds of the sale to the Prohibited Owner and to the Charitable Beneficiary as provided in this Section 7.3.4. The Prohibited Owner shall receive the lesser of (1) the price paid by the Prohibited Owner for the shares or, if the Prohibited Owner did not give value for the shares in connection with the event causing the shares to be held in the Trust (e.g., in the case of a gift, devise or other such transaction), the Market Price of the shares on the day of the event causing the shares to be held in the Trust and (2) the price per share received by the Trustee (net of any commissions and other expenses of sale) from the sale or other disposition of the shares held in the Trust. The Trustee may reduce the amount payable to the Prohibited Owner by the amount of dividends and other distributions which have been paid to the Prohibited Owner and are owed by the Prohibited Owner to the Trustee pursuant to Section 7.3.3. Any net sales proceeds in excess of the amount payable to the Prohibited Owner shall be immediately paid to the Charitable Beneficiary. If, prior to the discovery by the Corporation that shares of Capital Stock should have been transferred to the Trustee, such shares were instead first sold by a Prohibited Owner, then (i) such shares shall be deemed to have been sold on behalf of the Trust and (ii) to the extent that the Prohibited Owner received an amount for such shares that exceeds the amount that such Prohibited Owner was entitled to receive pursuant to this Section 7.3.4, such excess shall be paid to the Trustee upon demand.

Section 7.3.5 Purchase Right in Stock Transferred to the Trustee. Shares of Capital Stock transferred to the Trustee shall be deemed to have been offered for sale to the Corporation, or its designee, at a price per share equal to the lesser of (i) the price per share in the transaction that resulted in such transfer to the Trust (or, in the case of a devise or gift, the Market Price at the time of such devise or gift) and (ii) the Market Price on the date the Corporation, or its designee, accepts such offer. The Corporation may reduce the amount payable to the Prohibited Owner by the amount of dividends and other distributions which has

16

been paid to the Prohibited Owner and are owed by the Prohibited Owner to the Trustee pursuant to Section 7.3.3. The Corporation may pay the amount of such reduction to the Trustee for the benefit of the Charitable Beneficiary. The Corporation shall have the right to accept such offer discussed in the first sentence of this Section 7.3.5 until the Trustee has sold the shares held in the Trust pursuant to Section 7.3.4. Upon any such sale to the Corporation pursuant to this Section 7.3.5, the interest of the Charitable Beneficiary in the shares sold shall terminate and the Trustee shall distribute the net proceeds of the sale to the Prohibited Owner.

Section 7.3.6 Designation of Charitable Beneficiaries. By written notice to the Trustee, the Corporation shall designate one or more nonprofit organizations to be the Charitable Beneficiary of the interest in the Trust such that (i) the shares of Capital Stock held in the Trust would not violate the restrictions set forth in Section 7.2.1(a) in the hands of such Charitable Beneficiary and (ii) each such organization must be described in Section 501(c)(3) of the Code and contributions to each such organization must be eligible for deduction under each of Sections 170(b)(1)(A), 2055 and 2522 of the Code. Neither the failure of the Corporation to make such designation nor the failure of the Corporation to appoint the Trustee before the automatic transfer provided in Section 7.2.1(b) takes place shall make such transfer ineffective, provided that the Corporation thereafter makes such designation and appointment.

Section 7.4 NYSE Transactions. Nothing in this Article VII shall preclude the settlement of any transaction entered into through the facilities of the NYSE or any other national securities exchange or automated inter-dealer quotation system. The fact that the settlement of any transaction occurs shall not negate the effect of any other provision of this Article VII and any transferee in such a transaction shall be subject to all of the provisions and limitations set forth in this Article VII.

Section 7.5 Enforcement. The Corporation is authorized specifically to seek equitable relief, including injunctive relief, to enforce the provisions of this Article VII.

Section 7.6 Non-Waiver. No delay or failure on the part of the Corporation or the Board of Directors in exercising any right hereunder shall operate as a waiver of any right of the Corporation or the Board of Directors, as the case may be, except to the extent specifically waived in writing.

ARTICLE VIII

this sentence of this Article VIII shall be valid only if declared advisable by the Board of Directors and approved by the affirmative vote of holders of shares entitled to cast at least two-thirds of all the votes entitled to be cast on the matter.

ARTICLE IX

LIMITATION OF LIABILITY

Neither the amendment nor repeal of this Article IX, nor the adoption or amendment of any other provision of the Charter or Bylaws inconsistent with this Article IX, shall apply to or affect in any respect the applicability of the preceding sentence with respect to any act or failure to act which occurred prior to such amendment, repeal or adoption.
