ARTICLE VI

TREATMENT OF CONTRACTS AND LEASES

6.1    Assumed Contracts and Leases

(a)    Except as otherwise provided in the Plan, the Confirmation Order, or the Plan Supplement, as of the Effective Date, the Debtor shall be deemed to have assumed each executory contract or unexpired lease to which the Debtor is a party as of the Petition Date unless any such contract or lease (i) was previously assumed or rejected upon motion by a Final Order, (ii) previously expired or terminated pursuant to its own terms, (iii) is the subject of any pending motion, including to assume, to assume on modified terms, to reject or to make any other disposition filed by the Debtor on or before the Confirmation Date, or (iv) is subsequently rejected in accordance with the provisions of Section 6.2(c) of the Plan. The Confirmation Order shall constitute an order of the Bankruptcy Court under Bankruptcy Code Section 365(a) approving the contract and lease assumptions described above, as of the Effective Date.

(b)    Each executory contract and unexpired lease that is assumed shall include (i) all modifications, amendments, supplements, restatements, or other agreements made directly or indirectly by any agreement, instrument, or other document that in any manner affects such contract or lease and (ii) all contracts or leases appurtenant to the subject premises, including all easements, licenses, permits, rights, privileges, immunities, options, rights of first refusal, powers, uses, reciprocal easement agreements, vaults, tunnel or bridge agreements or franchises, and any other interests in real estate or rights in rem related to such premises, unless any of the foregoing agreements has been rejected pursuant to an order of the Bankruptcy Court.

(c)    To the extent applicable, all executory contracts or unexpired leases of the Debtor assumed pursuant to the Plan shall be deemed modified such that the transactions contemplated by the Plan shall not be a “change in control,” however such term may be defined in the relevant executory contract or unexpired lease, and any required consent under any such contract or lease shall be deemed satisfied by the Confirmation of the Plan.

6.2    Payments Related to Assumption of Contracts and Leases; Resolution of Assumption-Related Disputes

(a)    Any monetary amounts by which each executory contract and unexpired lease to be assumed pursuant to the Plan is in default shall be satisfied, under Bankruptcy Code Section 365(b)(1) by Cure. The Debtor shall, at its option, be permitted to resolve any dispute with respect to the amount of Cure either (i) through the Bankruptcy Court, or (ii) in the procedural manner in which a dispute regarding the amounts owed under a particular executory contract and unexpired lease would have been settled, determined, resolved or adjudicated if the Chapter 11 Case had not been commenced.

(b)    If there is a dispute regarding (i) the nature or amount of any Cure, (ii) the ability of the Reorganized Debtor to provide “adequate assurance of future performance” (within the meaning of Bankruptcy Code Section 365) under the contract or lease to be assumed, or (iii) any other matter pertaining to assumption, Cure shall occur following (y) the entry of a Final Order resolving the dispute and approving the assumption if such dispute is adjudicated in the Bankruptcy Court, or (z) as to amounts under the executory contract or unexpired lease, following the final resolution of such matter if the Debtor elected to handle such dispute in the procedural manner in which it would have been settled, determined, resolved or adjudicated if the Chapter 11 Case had not been commenced.

(c)    Notwithstanding any of the foregoing subsections of this Section 6.2, the Debtor shall be authorized to reject any executory contract or unexpired lease to the extent the Debtor, in the exercise of its sound business judgment, concludes that the amount of the Cure obligation as determined by Final Order or as otherwise finally resolved, renders assumption of such contract or lease unfavorable to the Debtor’s Estate. In the event the Debtor so rejects any previously assumed contract or lease, and such rejection gives rise to a Rejection Damages Claim, such Rejection Damages Claim arising out of such rejection shall be limited to the amount of the Allowed Rejection Damage Claim.

6.3    Rejected Contracts and Leases

The Debtor, with the consent of the Majority Consenting Noteholders, reserves the right, at any time prior to the Effective Date, except as otherwise specifically provided herein, to seek to reject any executory contract or unexpired lease to which the Debtor is a party and to file a motion requesting authorization for the rejection of any such contract or lease. Any executory contracts or unexpired leases that expire by their terms prior to the Effective Date are deemed to be rejected, unless previously assumed or otherwise disposed of by the Debtor.

6.4    Compensation and Benefit Programs

(a)    Except to the extent (i) otherwise provided for in the Plan, (ii) previously assumed or rejected by an order of the Bankruptcy Court entered on or before the Confirmation Date, (iii) the subject of a pending motion to reject filed by the Debtor on or before the Confirmation Date, or (iv) previously terminated, all Employee Programs in effect before the Effective Date, shall be deemed to be, and shall be treated as though they are, contracts that are assumed under the Plan. Nothing contained herein shall be deemed to modify the existing terms of Employee Programs, including, without limitation, the Debtor’s and the Reorganized Debtor’s rights of termination and amendment thereunder.

(b)    To the extent any “change in control” provision contained in any Employee Program would be triggered and payable solely as a result of the transactions contemplated by the Plan, such Employee Program shall not be assumed to the extent a waiver of the change in control provision is not executed by the employee having the benefit of such change in control provision, but otherwise shall remain in full force and effect and may be triggered as a result of any transactions occurring after the Effective Date.

(c)    As of the Effective Date, any and all equity incentive plans, equity ownership plans, or any other equity-based plans entered into before the Effective Date, including Claims arising from any change in control provision therein, shall be deemed to be, and shall be treated as though they are, contracts that are rejected pursuant to Bankruptcy Code Section 365 under the Plan pursuant to the Confirmation Order, provided, however, that nothing contained herein will impact any Cash payment components of any such equity-based plans.

(d)    The Reorganized Debtor affirms and agrees that (i) it is and will continue to be the contributing sponsor of the Employees’ Retirement Plan of USEC Inc. (the “Pension Plan”), a tax-qualified defined benefit pension plan insured by the Pension Benefit Guaranty Corporation under Title IV of the Employee Retirement Income Security Act of 1974 (“ERISA”), 29 U.S.C. §§ 1301-1461, et seq; (ii) the Pension Plan is subject to minimum funding requirements of ERISA and §§ 412 and 430 of the Internal Revenue Code; (iii) no provision of the Plan, the Confirmation Order, or Bankruptcy Code Section 1141, shall, or shall be construed to, discharge, release, or relieve the Debtor, the Reorganized Debtor, or any other party, in any capacity, from any liability with respect to the Pension Plan under any law, governmental policy, or regulatory provision; and (iv) neither the PBGC nor the Pension Plan shall be enjoined from enforcing such liability as a result of the Plan’s provisions for satisfaction, release and discharge of Claims. The Debtor further affirms and agrees that any discharge of liability provided under this Plan shall not operate to discharge any obligations it might have under applicable non-bankruptcy law with respect to any tax-qualified defined benefit pension plan maintained by Enrichment Corp, one of the Non-Debtor Subsidiaries, as a result of the Debtor’s status as a member of the “controlled group” for such pension plan. As of the Effective Date, the Reorganized Debtor shall contribute to the Pension Plan the amount necessary to satisfy minimum funding standards under sections 302 and 303 of ERISA, 29 U.S.C. §§ 1082 and 1083, and sections 412 and 430 of the Internal Revenue Code, to the extent that any such contributions were not made during the Chapter 11 Case.

6.5    Certain Indemnification Obligations

(a)    Indemnification Obligations owed to those of the Debtor’s directors, officers, and employees serving prior to, on, and after the Petition Date shall be deemed to be, and shall be treated as though they are, contracts that are assumed pursuant to Bankruptcy Code Section 365 under the Plan, and such Indemnification Obligations (subject to any defenses thereto) shall survive the Effective Date of the Plan and remain unaffected by the Plan, irrespective of whether obligations are owed in connection with a prepetition or postpetition occurrence.

(b)    Indemnification Obligations owed to any of the Debtor’s Professionals pursuant to Bankruptcy Code Sections 327 or 328 and order of the Bankruptcy Court, whether such Indemnification Obligations relate to the period before or after the Petition Date, shall be deemed to be, and shall be treated as though they are, contracts that are assumed pursuant to Bankruptcy Code Section 365 under the Plan.

6.6    Extension of Time to Assume or Reject

Notwithstanding anything set forth in Article [VI] of the Plan, in the event of a dispute as to whether a contract is executory or a lease is unexpired, the Debtor’s right to move to assume or reject such contract or lease shall be extended until the date that is thirty (30) days after entry of a Final Order by the Bankruptcy Court determining that the contract is executory or the lease is unexpired. The deemed assumption provided for in Section [6.1(a)] of the Plan shall not apply to any such contract or lease, and any such contract or lease shall be assumed or rejected only upon motion of the Debtor following the Bankruptcy Court’s determination that the contract is executory or the lease is unexpired.

6.7    Claims Arising from Assumption or Rejection

(a)    Except as otherwise provided in the Plan or by Final Order of the Bankruptcy Court, all (i) Allowed Claims arising from the assumption of any contract or lease shall be treated as Administrative Claims pursuant to Section [3.1(a)] of the Plan; and (ii) Allowed Rejection Damages Claims shall be treated as General Unsecured Claims pursuant to and in accordance with the terms of Section [3.2(d)] of the Plan.

(b)    If the rejection by the Debtor, pursuant to the Plan or otherwise, of a contract or lease results in a Rejection Damages Claim, then such Rejection Damages Claim shall be forever barred and shall not be enforceable against the Debtor or the Reorganized Debtor or the properties of either of them unless a Proof of Claim is (i) filed with the Claims Agent on or before the date that is the first Business Day that is thirty (30) days after the Bankruptcy Court’s entry of an order authorizing the rejection of a contract or lease and (ii) contemporaneously with such filing, served upon (a) if such filing occurs prior to the Effective Date, counsel to the Debtor and counsel to the Consenting Noteholders or (b) if such filing occurs after the Effective Date, counsel to the Reorganized Debtor. All rights of the Debtor or the Reorganized Debtor, as applicable, to object to any Rejection Damages Claim are reserved.

ARTICLE VII

PROVISIONS GOVERNING DISTRIBUTIONS

7.1    Determination of Allowability of Claims and Interests and Rights to Distributions

(a)    Only holders of Allowed Claims and Allowed Interests shall be entitled to receive distributions under the Plan.

(b)    Unless otherwise provided in the Plan, the Disclosure Statement or an order of the Bankruptcy Court (including, inter alia, with respect to Rejection Damage Claims and Claims subject to Bankruptcy Code Section 510(b)), there shall be no requirement for holders of Claims to file Proofs of Claim or Requests for Payment or for holders of Interests to file any proofs of interest. With respect to Filed Claims or filed Proofs of Interest, the Debtor or the Reorganized Debtor shall have the right to object to the Proofs of Claim, Requests for Payment or Proofs of Interest in the Bankruptcy Court by the Claims Objection Deadline, but shall not be required to do so. In no event shall the failure to object in the Bankruptcy Court to any Filed Claim or any proof of interest result in the deemed allowance of any such Claim or Interest. The Debtor or the Reorganized Debtor shall have the right to dispute all alleged Claims (whether Filed Claims or Unfiled Claims) and alleged Interests (whether or evidenced by a filed proof of interest) in any manner that would have been available to it had the Chapter 11 Case not been filed (including, without limitation, by declining to pay any alleged Claim or to recognize any alleged Interest), or may elect in its discretion to have any alleged Claim or Interest adjudicated by the Bankruptcy Court.

(c)    No distributions shall be made on Disputed Claims or Disputed Interests until and unless such Disputed Claims become Allowed Claims and such Disputed Interests become Allowed Interests. No reserve shall be required with respect to any Disputed Claim or Disputed Interest.

7.2    Timing of Distributions to Holders of Allowed Claims and Allowed Interests

Except as otherwise provided herein or as ordered by the Bankruptcy Court, all distributions to holders of Allowed Claims and Allowed Interests as of the applicable Distribution Date shall be made on or as soon as practicable after the applicable Distribution Date, but in no event later than the first Business Day that is twenty (20) days after such date; provided, however, that distributions on account of Noteholder Claims hereunder shall be made on the Effective Date. The Reorganized Debtor or the Disbursing Agent shall have the right, in its discretion, to accelerate any Distribution Date occurring after the Effective Date if the facts and circumstances so warrant.

7.3    Procedures for Making Distributions to Holders of Allowed Claims and Allowed Interests

(a)    On or before the Effective Date, the Debtor (with the consent of the Majority Consenting Noteholders) shall designate the Person(s) (whether the Reorganized Debtor and/or one or more independent third parties) to serve as the Disbursing Agent(s) under the Plan; provided, however, that (i) the Indenture Trustee shall serve as the Disbursing Agent with respect to the Noteholder Claims and (ii) the Indenture Trustee shall transmit distributions to the Noteholders subject to the right of the Indenture Trustee to assert the Indenture Trustee’s Charging Lien against such distributions. If any Disbursing Agent is an independent third party, such Disbursing Agent shall receive, without further Bankruptcy Court approval, reasonable compensation for distribution services rendered pursuant to the Plan and reimbursement of reasonable out of pocket expenses incurred in connection with such services from the Reorganized Debtor. No Disbursing Agent shall be required to give any bond or surety or other security for the performance of its duties unless otherwise ordered by the Bankruptcy Court. Notwithstanding any provision contained in this Plan to the contrary, the distribution provisions contained in the Old Indenture shall continue in effect to the extent necessary to authorize the Indenture Trustee to receive and distribute to the Noteholders pursuant to this Plan on account of Allowed Noteholder Claims and shall terminate completely upon completion of all such distributions.

(b)    The Disbursing Agent(s) shall make distributions to the holders of the Allowed Claims and Allowed Interests in the same manner and to the same addresses as payments are made in the ordinary course of the Debtor’s businesses; provided, however, that if a Filed Claim or filed Proof of Interest references a different payment address, the address on the Filed Claim or filed Proof of Interest shall be used.

(c)     If any holder’s distribution is returned as undeliverable, no further distributions to such holder shall be made unless and until the Disbursing Agent is notified by the Debtor, the Claims Agent, or such holder of such holder’s then current address, at which time all missed distributions shall be made to such holder without interest. If any distribution is made by check and such check is not returned but remains uncashed for six (6) months after the date of such check, the Disbursing Agent may cancel and void such check, and the distribution with respect thereto shall be deemed undeliverable. If, pursuant to Section [7.7] of the Plan, any holder is requested to provide an applicable Internal Revenue Service form or to otherwise satisfy any tax withholding requirements with respect to a distribution and such holder fails to do so within six (6) months of the date of such request, such holder’s distribution shall be deemed undeliverable.

(d)    Unless otherwise agreed between the Reorganized Debtor and the applicable Disbursing Agent, amounts in respect of returned or otherwise undeliverable or unclaimed distributions made by the Disbursing Agent on behalf of the Reorganized Debtor shall be returned to the Reorganized Debtor until such distributions are claimed. All claims for returned or otherwise undeliverable or unclaimed distributions must be made (i) on or before the first (1st) anniversary of the Effective Date or (ii) with respect to any distribution made later than such date, on or before six (6) months after the date of such later distribution; after which date all undeliverable property shall revert to the Reorganized Debtor free of any restrictions thereon and the claims of any holder with respect to such property shall be discharged and forever barred, notwithstanding any federal or state escheat laws to the contrary. In the event of a timely claim for any returned or otherwise undeliverable or unclaimed distribution, the Reorganized Debtor shall deliver the applicable distribution amount or property to the Disbursing Agent for distribution pursuant to the Plan.

7.4    Calculation of Distribution Amounts of New Securities

No fractional shares of New Securities shall be issued or distributed under the Plan. Each Person entitled to receive New Securities shall receive the total number of whole shares of New Common Stock or their pro rata share in principal amount of New Notes, whichever is relevant, to which such Person is entitled. Whenever any distribution to a particular Person would otherwise call for distribution of a fraction of New Securities, the actual distribution of such New Securities shall be rounded to the next higher or lower whole number as follows: (a) fractions one-half (½) or greater shall be rounded to the next higher whole number and (b) fractions of less than one-half (½) shall be rounded to the next lower whole number. Notwithstanding the foregoing, (a) if the Person is entitled to New Common Stock and rounding to the next lower whole number would result in such Person receiving zero shares of New Common Stock, such Person shall receive one (1) share of New Common Stock; and (b) if the Person is entitled to a pro rata share in principal amount of New Notes and rounding to the next lower whole number would result in such Person receiving zero dollars worth of New Notes, such Person shall receive a New Note in the principal amount of one $1.00 (One Dollar). If two or more Persons are entitled to fractional entitlements and the aggregate amount of New Securities that would otherwise be issued to such Persons with respect to such fractional entitlements as a result of such rounding exceeds the number of whole New Securities which remain to be allocated, the Disbursing Agent shall allocate the remaining whole New Securities to such holders by random lot or such other impartial method as the Disbursing Agent deems fair. Upon the allocation of all of the whole New Securities authorized under the Plan, all remaining fractional portions of the entitlements shall be cancelled and shall be of no further force and effect. The Disbursing Agent shall have the right to carry forward to subsequent distributions any applicable credits or debits arising from the rounding described in this paragraph.

7.5    Application of Distribution Record Date

On the applicable Distribution Record Date, (a) for all Claims other than Noteholder Claims, the Debtor’s books and records for Unfiled Claims and the claims register maintained by the Claims Agent for Filed Claims, (b) for Noteholder Claims, the transfer ledgers for the Old Notes and (c) for Interests, the records of the Debtor in the case of the Preferred Stock Interests/Claims and the records of the stock transfer agent in the case of the Common Stock Interests/Claims, shall be closed for purposes of determining the record holders of Claims or Interests, and there shall be no further changes in the record holders of any Claims or Interests. Except as provided herein, the Reorganized Debtor, the Disbursing Agent(s), the Indenture Trustee, and each of their respective agents, successors, and assigns shall have no obligation to recognize any transfer of Claims or Interests occurring after the Distribution Record Date and shall be entitled instead to recognize and deal for all purposes hereunder with only those record holders stated on the applicable books and records, claims registers or transfer ledgers as of 5:00 p.m. prevailing Eastern time on the Distribution Record Date irrespective of the number of distributions to be made under the Plan to such Persons or the date of such distributions.

7.6    Surrender of Cancelled Old Securities

As a condition precedent to receiving any distribution on account of its Allowed Claim, each record Noteholder shall be deemed to have surrendered the Old Notes or other documentation underlying each Noteholder Claim, and all such surrendered Old Notes and other documentation shall be deemed to be cancelled pursuant to Section [5.4] of the Plan, except to the extent otherwise provided herein. As a condition precedent to receiving any distribution on account of its Allowed Interest, each holder of an Allowed Common Stock Interest/Claim and an Allowed Preferred Stock Interest/Claim shall be deemed to have surrendered any stock certificate or other documentation underlying each such Interest/Claim, and any such stock certificates and other documentation shall be deemed to be cancelled pursuant to Section [5.4] of the Plan.

7.7    Withholding and Reporting Requirements

In connection with the Plan and all distributions hereunder, the applicable Disbursing Agent shall, to the extent applicable, comply with all tax withholding and reporting requirements imposed by any federal, state, provincial, local, or foreign taxing authority, and all distributions hereunder shall be subject to any such withholding and reporting requirements. The Disbursing Agent(s) shall be authorized to take any and all actions that may be necessary or appropriate to comply with such withholding and reporting requirements including, without limitation, requiring that, as a condition to the receipt of a distribution, the holder of an Allowed Claim or Allowed Interest complete the appropriate IRS Form W-8 or IRS Form W-9, as applicable to each holder. Notwithstanding any other provision of the Plan, (a) each holder of an Allowed Claim or Allowed Interest that is to receive a distribution pursuant to the Plan shall have sole and exclusive responsibility for the satisfaction and payment of any tax obligations imposed on such holder by any governmental unit, including income and other tax obligations, on account of such distribution, and (b) no distribution shall be made to or on behalf of such holder pursuant to the Plan unless and until such holder has made arrangements satisfactory to the applicable Disbursing Agent to allow it to comply with its tax withholding and reporting requirements. Any property to be distributed pursuant to the Plan shall, pending the implementation of such arrangements, be treated as an undeliverable distribution to be held by the Indenture Trustee or the Disbursing Agent, as the case may be, until such time as the Disbursing Agent is satisfied with the holder’s arrangements for any withholding tax obligations.

7.8    Setoffs

The Reorganized Debtor may, but shall not be required to, set off against any Claim, and the payments or other distributions to be made pursuant to the Plan in respect of such Claim, claims of any nature whatsoever that the Debtor or the Reorganized Debtor may have against the holder of such Claim; provided, however, that neither the failure to do so nor the allowance of any Claim hereunder shall constitute a waiver or release by the Reorganized Debtor of any such claim that the Debtor or the Reorganized Debtor may have against such holder.

7.9    Prepayment

Except as otherwise provided in the Plan, any ancillary documents entered into in connection herewith, or the Confirmation Order, the Reorganized Debtor shall have the right to prepay, without penalty, all or any portion of an Allowed Claim at any time; provided, however, that any such prepayment shall not be violative of, or otherwise prejudice, the relative priorities and parities among the Classes of Claims.

7.10    Allocation of Distributions

All distributions received under the Plan by holders of applicable Claims shall be deemed to be allocated first to the principal amount of such Claim as determined for United States federal income tax purposes and then to accrued interest, if any, with respect to such Claim.

Subject to the provisions of this Section C.(ii) of this Article FOURTH, each Initial Investor Director or the Investor Director, as applicable, shall serve until the next annual meeting of the stockholders of the Corporation and until his or her successor is elected and qualified in accordance with this Section C.(ii) of this Article FOURTH and the By-Laws, unless any such Initial Investor Director or the Investor Director, as applicable, is earlier removed in accordance with the By-Laws, resigns or is otherwise unable to serve; provided , however , that only the holders of a majority of the voting power of the outstanding Class B Common Stock may remove any such Initial Investor Director or the Investor Director, as applicable, without cause at any time, and the holders of a majority of the voting power of the outstanding shares of the capital stock of the Corporation entitled to vote on the matter may remove any such Initial Investor Director or the Investor Director, as applicable, with cause at any time.  Subject to the provisions of this Section C.(ii) of this Article FOURTH, in the event any Initial Investor Director or the Investor Director, as applicable, is removed, resigns or is unable to serve as a member of the Board of Directors, the holders of a majority of the voting power of the outstanding Class B Common Stock, voting as a separate class to the exclusion of the holders of any other Common Stock and any series of Preferred Stock, shall have the right to fill such vacancy.  Each Initial Investor Director or the Investor Director, as applicable, may only be elected to the Board of Directors by the holders of the Class B Common Stock in accordance with this Section C.(ii) of this Article FOURTH, and each such Initial Investor Director’s or the Investor Director’s seat, as applicable, shall otherwise remain vacant.

Each holder of Class A Common Stock shall be entitled to one vote for each share of Class A Common Stock held of record by such holder as of the applicable record date on any matter that is submitted to a vote of the stockholders of the Corporation; provided , however , that, except as otherwise required by law, holders of Class A Common Stock, as such, shall not be entitled to vote on any amendment to this Certificate of Incorporation (including any certificate of designation relating to any series of Preferred Stock) that relates solely to the terms of one or more outstanding series of Preferred Stock or Class B Common Stock if the holders of such affected class or series are entitled, either separately or together with the holders of one or more other such class or series, to vote thereon pursuant to this Certificate of Incorporation (including any certificate of designation relating to any series of Preferred Stock) or pursuant to the DGCL.

Notwithstanding Section C.(ii)(a) of this Article FOURTH, the holders of Class B Common Stock shall be entitled to vote together with the holders of Class A Common Stock (and any other class or series of capital stock entitled to vote on the matter with the Class A Common Stock) as a single class with respect to any

transactions involving a merger of the Corporation or sale of substantially all of the Corporation’s assets, which must be submitted to the Corporation’s stockholders pursuant to the DGCL; provided , however , that each holder of Class B Common Stock shall be entitled to (A) one vote for each outstanding share of Class B Common Stock held of record by such holder as of the applicable record date, after equitable adjustments for any previous stock splits, stock dividends, reorganizations or similar transactions with respect to the Class A Common Stock, but only to the extent that the aggregate voting power of all of the outstanding Class B Common Stock does not exceed 20% of the total voting power of all outstanding shares of all classes and series of capital stock entitled to vote thereon or (B) if pursuant to clause (A) the aggregate voting power of all of the outstanding Class B Common Stock would exceed 20% of the total voting power of all outstanding shares of all classes and series of capital stock entitled to vote on the matter, such fraction of one vote for each share of Class B Common Stock held of record by such holder as of the applicable record date, after equitable adjustments for any previous stock splits, stock dividends, reorganizations or similar transactions with respect to the Class A Common Stock, such that the aggregate voting power of all of the outstanding Class B Common Stock equaled 20% of the total voting power of all outstanding shares of all classes and series of capital stock entitled to vote thereon.

Notwithstanding Section C.(ii)(a) of this Article FOURTH, the vote or consent of the holders of at least a majority of the outstanding shares of Class B Common Stock, voting as a separate class to the exclusion of the holders of the Class A Common Stock and the Preferred Stock then outstanding and entitled to vote thereon, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose, shall be necessary for effecting or validating any amendment, alteration or repeal of any provision of this Certificate of Incorporation (by merger, consolidation or otherwise) so as to adversely affect any of the powers, preferences, qualifications, limitations, restrictions and relative participating, optional or other rights of Class B Common Stock.

Dividends and Distributions . Subject to applicable law and the rights, if any, of the holders of any outstanding series of Preferred Stock or any class or series of capital stock having a preference over or the right to participate with the Class A Common Stock and Class B Common Stock with respect to the payment of dividends, dividends may be declared by the Board of Directors and paid on the Class A Common Stock and Class B Common Stock out of the assets of the Corporation that are by law available therefor at such times and in such amounts as the Board of Directors in its discretion shall determine.  Except as otherwise required by the DGCL, in any circumstance where the Corporation may declare dividends or otherwise make distributions (including, without limitation, any distribution on liquidation, dissolution or winding-up of the Corporation) on the Class A Common Stock or Class B Common Stock, the Corporation shall declare the same per share dividends or make the same per share distributions, as the case may be, on such other class of stock; provided, however, that if any such dividends or distributions are declared with respect to the Class A Common Stock in the form of additional shares of Class A Common Stock (or rights to acquire Class A Common Stock), such dividends or distributions shall be made with respect to Class B Common Stock in the form of an equivalent number of shares of Class B Common Stock (or rights to acquire Class B Common Stock) and if any such dividends or distributions are declared with respect to Class B Common Stock in the form of additional shares of Class B Common Stock (or rights to acquire Class B Common Stock), such dividends or distributions shall be made with respect to the Class A Common Stock in the form of an equivalent number of shares of Class A Common Stock (or rights to acquire Class A Common Stock).

Voluntary or Involuntary Liquidation .  Subject to the rights of the holders of any series of Preferred Stock outstanding at any time, in the event of any liquidation, dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary, holders of the Class A Common Stock and the holders of Class B Common Stock shall be entitled to share equally, on a per share basis, in all assets of the Corporation of whatever kind available for distribution to the holders of the Class A Common Stock and Class B Common Stock.

Subdivision or Combination .  If the Corporation in any manner subdivides or combines the outstanding shares of any of the Class A Common Stock or Class B Common Stock, then the outstanding shares of the Class A Common Stock or Class B Common Stock, as applicable, will be subdivided or combined in the same manner.

Equal Status .  Except as expressly provided in this Article FOURTH, shares of Class A Common Stock and Class B Common Stock shall have the same rights, powers, preferences and restrictions and rank equally, share ratably and be identical in all respect as to all matters.  In any merger, consolidation, reorganization or other business combination, the consideration received per share by the holders of the Class A Common Stock and the holders of the Class B Common Stock in such merger, consolidation, reorganization or other business combination shall be identical; provided, however, that if such consideration consists, in whole or in part, of shares of capital stock of, or other equity interests in, the Corporation or any other corporation, partnership, limited liability company or other entity, then the designation and the powers, preferences and relative, participating, optional and other rights and the qualifications, limitations and restrictions of such shares of capital stock or other equity interests may differ to the extent that the designation and the powers, preferences and relative, participating, optional and

other rights and the qualifications, limitations and restrictions of the shares of Class A Common Stock and the Class B Common Stock differ as provided herein (including, without limitation, with respect to the voting rights and conversion provisions hereof) if and to the extent necessary due to regulatory requirements or restrictions applicable to the entity surviving such merger, consolidation, reorganization or other business combination that are similar in nature to those applicable to the Corporation; and provided, further, that if the holders of the Class A Common Stock or the holders of the Class B Common Stock are granted the right to elect to receive one of two or more alternative forms of consideration, the foregoing provision shall be deemed satisfied if holders of the other class are granted identical election rights, subject to the preceding proviso.

Automatic Conversion .

Subject to Section C.(viii) of this Article FOURTH, a share of Class B Common Stock shall be automatically converted, without any action on the part of the Corporation (other than the subsequent exchange of Class B Common Stock certificates for Class A Common Stock certificates or, in the case of uncertificated shares of Class B Common Stock, upon receipt of proper transfer instructions from the registered holder of the shares of Class B Common Stock or by his, her or its attorney lawfully constituted in writing, and upon payment of all necessary transfer taxes and compliance with appropriate procedures for transferring shares in uncertificated form), any holder of Class B Common Stock or any other Person, into one fully paid and nonassessable share of Class A Common Stock upon a Third-Party Transfer of such share, subject to equitable adjustments for any previous stock splits, stock dividends, reorganizations or similar transactions with respect to the Class A Common Stock.

In the event of any automatic conversion pursuant to the terms of Section C.(vii)(a) of this Article FOURTH, the conversion shall be deemed to have been effected upon such Third-Party Transfer (the “ Class B Common Stock Automatic Conversion Time ”).  At the Class B Common Stock Automatic Conversion Time, the certificate or certificates that represented the shares of Class B Common Stock that were so converted immediately prior to such conversion (the “ Converted Class B Common Stock ”) shall, automatically and without further action, represent the same number of fully paid and non-assessable shares of Class A Common Stock, subject to equitable adjustments for any previous stock splits, stock dividends, reorganizations or similar transactions with respect to the Class A Common Stock.  Permitted Holders of the Converted Class B Common Stock shall deliver their certificates, duly endorsed in blank or accompanied by proper instruments of transfer, in form reasonably satisfactory to the Corporation, duly executed by such Permitted Holder or such Permitted Holder’s authorized attorney to the principal office of the Corporation (or such other office or agency (including the transfer agent, if applicable) of the Corporation as it may designate by notice in writing to the registered Permitted Holder at the address of such Permitted Holder appearing on the books of the Corporation), together with a written notice stating the name or names (with addresses) and denominations in which the certificate or certificates representing such shares of Class A Common Stock are to be issued and including instructions for delivery thereof.  Upon such delivery, the Corporation or its agent shall promptly issue and deliver at such stated address to such holder of shares of Class A Common Stock a certificate or certificates representing the number of shares of Class A Common Stock to which such holder is entitled by reason of such conversion, and shall cause such shares of Class A Common Stock to be registered in the name of such holder.  The Person entitled to receive the shares of Class A Common Stock issuable upon such conversion shall be treated for all purposes as the record holder of such shares of Class A Common Stock at and as of Class B Common Stock Automatic Conversion Time, and the rights of such Person as a holder of shares of Class B Common Stock that have been converted shall cease and terminate at and as of Class B Common Stock Automatic Conversion Time, in each case without regard to any failure by such Permitted Holder to deliver the certificates or the notice required by this Section.

Restrictions .  

Notwithstanding anything in this Certificate of Incorporation to the contrary and unless the Corporation, in its sole discretion, otherwise agrees in writing, Permitted Holders may not transfer shares of Class B Common Stock if such Transfer would require approvals from or filings with any Regulatory Body in order not to adversely affect the Permits or regulatory status of the Corporation or its Subsidiaries, unless such approvals and/or filings have been made and received; provided , however , this Section C.(viii)(a) of this Article FOURTH shall not apply to any transfer where the transferee received Class A Common Stock pursuant to the terms hereof.

(b) the redemption price of such shares may be paid in cash, securities or any combination thereof and the value of any securities constituting all or any part of the redemption price shall be determined by the Board of Directors in good faith;

A quorum, once established, shall not be broken by the withdrawal of enough votes to leave less than a quorum. If, however, such quorum shall not be present or represented at any meeting of the stockholders, the stockholders entitled to vote thereat, present in person or represented by proxy, shall have power to adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present or represented.

Any copy, facsimile telecommunication or other reliable reproduction of the writing or transmission authorizing another person or persons to act as proxy for a stockholder may be substituted or used in lieu of the original writing or transmission for any and all purposes for which the original writing or transmission could be used; provided that such copy, facsimile telecommunication or other reproduction shall be a complete reproduction of the entire original writing or transmission.

Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting, or, if not so specified, at the place where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder of the Corporation who is present.

Section 8.    Stock Ledger. The stock ledger of the Corporation shall be the only evidence as to who are the stockholders entitled to examine the stock ledger, the list required by Section 7 of this Article II or the books of the Corporation, or to vote in person or by proxy at any meeting of stockholders.

Section 9.    Nomination of Directors. Only persons who are nominated in accordance with the following procedures shall be eligible for election as directors of the Corporation.

In addition to any other applicable requirements, for a nomination to be made by a stockholder, such stockholder must have given timely notice thereof in proper written form to the Secretary of the Corporation.

To be timely, a stockholder’s notice to the Secretary must be delivered to or mailed and received at the principal executive offices of the Corporation not less than ninety nor more than one hundred twenty calendar days prior to the first anniversary date of the Annual Meeting for the prior year; provided, however, that in the event that the date of the Annual Meeting is more than thirty days before or more than sixty days after such anniversary date, notice by the stockholder to be timely must be so received not later than the close of business on the tenth day following the day on which such notice of the date of the Annual Meeting was mailed or such public disclosure of the date of the Annual Meeting was made, whichever first occurs. In no event shall the public announcement of an adjournment of an Annual Meeting commence a new time period for the giving of a stockholder notice as described above.

To be in proper written form, a stockholder’s notice to the Secretary must set forth (a) as to each person whom the stockholder proposes to nominate for election as a director (i) the name, age, business address and residence address of the person, (ii) the principal occupation or employment of the person, (iii) the class or series and number of shares of capital stock of the Corporation that are owned beneficially or of record by the person and (iv) any other information relating to the person that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for election of directors pursuant to Section 14 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations promulgated thereunder; and (b) as to the stockholder giving the notice (i) the name and record address of such stockholder, (ii) the class or series and number of shares of capital stock of the Corporation that are owned beneficially or of record by such stockholder, (iii) a description of all arrangements or understandings between such stockholder and each proposed nominee and any other person or persons (including their names) pursuant to which the nomination(s) are to be made by such stockholder, (iv) a representation that such stockholder intends to appear in person or by proxy at the meeting to nominate the persons named in its notice, (v) a statement, signed under oath and in such reasonable detail as the Board of Directors may require, that such stockholder is not a foreign person (as defined in the Certificate of Incorporation) or under the control of a foreign person and that such stockholder is not a Contravening Person (as defined in the Certificate of Incorporation) or under the control of a Contravening Person, (vi) an undertaking to notify the Corporation if the statement specified in clause (v) becomes untrue in any respect from the date such statement is given up to and including the date and time of the vote for the proposed nominee and (vii) any other information relating to such stockholder that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for election of directors pursuant to Section 14 of the Exchange Act and the rules and regulations promulgated thereunder. Such notice must be accompanied by a written consent of each proposed nominee to being named as a nominee and to serve as a director if elected.

No person shall be eligible for election as a director of the Corporation unless nominated in accordance with the procedures set forth in this Section 9. If the Chairman of the meeting determines (a) that a nomination was not made in accordance with the foregoing procedures, (b) that at the date and time of the vote for the proposed nominee the stockholder who nominated such nominee is a foreign person or under the control of a foreign person or (c) that at the date and time of the vote for the proposed nominee the stockholder who nominated such nominee is a Contravening Person (as defined in the Certificate of Incorporation) or under the control of a Contravening Person, the Chairman shall declare to the meeting that the nomination was defective and such defective nomination shall be disregarded.

Nothing in this Section 9 shall be deemed to affect any rights of the holders of any series of Preferred Stock (as defined in the Certificate of Incorporation) or holders of Class B Common Stock (as defined in the Certificate of Incorporation) to elect directors pursuant to any applicable provisions of the Certificate of Incorporation.

Section 10.    Business at Annual Meetings. No business may be transacted at an Annual Meeting, other than business that is either (a) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board of Directors (or any duly authorized committee thereof), (b) otherwise properly brought before the Annual Meeting by or at the direction of the Board of Directors (or any duly authorized committee thereof) or (c) otherwise properly brought before the Annual Meeting by any stockholder of the Corporation (i) who is a stockholder of record on the date of the giving of the notice provided for in

this Section 10 and on the record date for the determination of stockholders entitled to vote at such Annual Meeting and (ii) who complies with the notice procedures set forth in this Section 10.

In addition to any other applicable requirements, for business to be properly brought before an Annual Meeting by a stockholder, such stockholder must have given timely notice thereof in proper written form to the Secretary of the Corporation.

To be timely, a stockholder’s notice to the Secretary must be delivered to or mailed and received at the principal executive offices of the Corporation not less than ninety nor more than one hundred twenty calendar days prior to the first anniversary date of the Annual Meeting for the prior year; provided, however, that in the event that the date of the Annual Meeting is more than thirty days before or more than sixty days after such anniversary date, notice by the stockholder to be timely must be so received not later than the close of business on the tenth day following the day on which such notice of the date of the Annual Meeting was mailed or such public disclosure of the date of the Annual Meeting was made, whichever first occurs. In no event shall the public announcement of an adjournment of an Annual Meeting commence a new time period for the giving of a stockholder’s notice as described above.

To be in proper written form, a stockholder’s notice to the Secretary must set forth as to each matter such stockholder proposes to bring before the Annual Meeting (i) a brief description of the business desired to be brought before the Annual Meeting and the reasons for conducting such business at the Annual Meeting, (ii) the name and record address of such stockholder, (iii) the class or series and number of shares of capital stock of the Corporation that are owned beneficially or of record by such stockholder, (iv) a description of all arrangements or understandings between such stockholder and any other person or persons (including their names) in connection with the proposal of such business by such stockholder and any material interest of such stockholder in such business and (v) a representation that such stockholder intends to appear in person or by proxy at the Annual Meeting to bring such business before the meeting.

No business shall be conducted at the Annual Meeting of Stockholders except business brought before the Annual Meeting in accordance with the procedures set forth in this Section 10, provided, however, that, once business has been properly brought before the Annual Meeting in accordance with such procedures, nothing in this Section 10 shall be deemed to preclude discussion by any stockholder of any such business.

When authorizing such issue of a new certificate, the Board of Directors may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed certificate, or his or her legal representative, to advertise the same in such manner as the Board of Directors shall require and/or to give the Corporation a bond in such sum as it may direct as indemnity against any claim that may be made against the Corporation with respect to the certificate alleged to have been lost, stolen or destroyed or the issuance of such new certificate.

No transfer shall be valid as against the Corporation for any purpose until it shall have been entered in the stock records of the Corporation by an entry showing from and to whom transferred.

Section 5.    Record Date.

(a)    In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which record date shall not be

more than sixty nor less than ten days before the date of such meeting. If no record date is fixed by the Board of Directors, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting.

Attendance of a person at a meeting, present by person or represented by proxy, shall constitute a waiver of notice of such meeting, except where the person attends the meeting for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the stockholders, directors or members of a committee of directors need be specified in any written waiver of notice unless so required by law, the Certificate of Incorporation or these Bylaws.

ARTICLE VIII

INDEMNIFICATION

Section 1.    Power to Indemnify in Actions, Suits or Proceedings other Than Those by or in the Right of the Corporation. Subject to Section 3 of this Article VIII, the Corporation shall indemnify 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 he or she is or was a director or officer of the Corporation, or is or was a director or officer of the Corporation serving at the request of the Corporation as a director or officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan 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 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, 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.

Section 2.    Power to Indemnify in Actions, Suits or Proceedings by or in the Right of the Corporation. Subject to Section 3 of this Article VIII, the Corporation shall indemnify 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 he or she is or was a director or officer of the Corporation, or is or was a director or officer of the Corporation serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan 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; except that no 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 Delaware Court of Chancery 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 Delaware Court of Chancery or such other court shall deem proper.

Section 3.    Authorization of Indemnification. Any indemnification under this Article VIII (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the director or officer is proper in the circumstances because he or she has met the applicable standard of conduct set forth in Section 1 or Section 2 of this Article VIII, as the case may be. Such determination shall be made, with respect to a person who is a director or officer at the time of such determination, (i) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, or (ii) by a committee of such directors designated by a majority vote of such directors, even though less than a quorum, or (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (iv) by the stockholders. Such determination shall be made, with respect to former directors and officers, by any person or persons having the authority to act on the matter on behalf of the Corporation. To the extent, however, that a present or former director or officer of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding described above, or in defense of any claim, issue or matter therein, he or she shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection therewith, without the necessity of authorization in the specific case.

Section 4.    Good Faith Defined. For purposes of any determination under Section 3 of this Article VIII, a person shall be deemed to have 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, or, with respect to any criminal action or proceeding, to have had no reasonable cause to believe his or her conduct was unlawful, if his or her action is based on the records or books of account of the Corporation or another enterprise, or on information supplied to him or her by the officers of the Corporation or another enterprise in the course of their duties, or on the advice of legal counsel for the Corporation or another enterprise or on information or records given or reports made to the Corporation or another enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Corporation or another enterprise. The term “another enterprise” as used in this Section 4 shall

mean any other corporation or any partnership, joint venture, trust, employee benefit plan or other enterprise of which such person is or was serving at the request of the Corporation as a director, officer, employee or agent. The provisions of this Section 4 shall not be deemed to be exclusive or to limit in any way the circumstances in which a person may be deemed to have met the applicable standard of conduct set forth in Sections 1 or 2 of this Article VIII, as the case may be.

Section 5.    Indemnification by a Court. Notwithstanding any contrary determination in the specific case under Section 3 of this Article VIII, and notwithstanding the absence of any determination thereunder, any director or officer may apply to any court of competent jurisdiction in the State of Delaware for indemnification to the extent otherwise permissible under Sections 1 and 2 of this Article VIII. The basis of such indemnification by a court shall be a determination by such court that indemnification of the director or officer is proper in the circumstances because he or she has met the applicable standards of conduct set forth in Sections 1 or 2 of this Article VIII, as the case may be. Neither a contrary determination in the specific case under Section 3 of this Article VIII nor the absence of any determination thereunder shall be a defense to such application or create a presumption that the director or officer seeking indemnification has not met any applicable standard of conduct. Notice of any application for indemnification pursuant to this Section 5 shall be given to the Corporation promptly upon the filing of such application. If successful, in whole or in part, the director or officer seeking indemnification shall also be entitled to be paid the expense of prosecuting such application.

Section 6.    Expenses Payable in Advance. Expenses incurred by a director or officer in defending any civil, criminal, administrative or investigative action, suit or proceeding shall be paid by the Corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified by the Corporation as authorized in this Article VIII.

Section 7.    Nonexclusivity of Indemnification and Advancement of Expenses. The indemnification and advancement of expenses provided by or granted pursuant to this Article VIII shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any Bylaw, statute, agreement, contract, vote of stockholders or disinterested directors or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding such office, it being the policy of the Corporation that indemnification of the persons specified in Sections 1 and 2 of this Article VIII shall be made to the fullest extent permitted by law. The provisions of this Article VIII shall not be deemed to preclude the indemnification of any person who is not specified in Sections 1 or 2 of this Article VIII but whom the Corporation has the power or obligation to indemnify under the provisions of the General Corporation Law of the State of Delaware, or otherwise.

Section 8.    Primacy of Indemnification. The Corporation hereby acknowledges that any person that may be indemnified pursuant to these Bylaws (an “Indemnitee”) may have certain rights to indemnification, advancement of expenses and/or insurance provided by an employer, partner or affiliate of such person and certain of their affiliates (collectively, the “Third Party Indemnitors”). The Corporation hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to each Indemnitee are primary and any obligation of the Third Party Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by Indemnitee are secondary), (ii) that it shall be required to advance the full amount of expenses incurred by Indemnitee and shall be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by these Bylaws and the Certificate of Incorporation (or any other agreement between the Corporation and an Indemnitee), without regard to any rights Indemnitee may have against the Third Party Indemnitors, and (iii) that it irrevocably waives, relinquishes and releases the Third Party Indemnitors from any and all claims against the Third Party Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Corporation further agrees that no advancement or payment by the Third Party Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Corporation shall affect the foregoing and the Third Party Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee against the Corporation. The Corporation agrees that the Third Party Indemnitors are express third party beneficiaries of the terms of this Section 8 or ARTICLE VIII.

Section 9.    Insurance. The Corporation may purchase and maintain insurance on behalf of any person who is or was or shall be a director, officer or employee of the Corporation, or is or was or shall be a director, officer or employee of the Corporation serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise against any liability asserted against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the Corporation would have the power or the obligation to indemnify him or her against such liability under the provisions of this Article VIII.

Section 10.    Certain Definitions. For purposes of this Article VIII, references to “the Corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a

consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers or employees, so that any person who is or was a director, officer or employee of such constituent corporation, or is or was a director, officer or employee of such constituent corporation serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise, shall stand in the same position under the provisions of this Article VIII with respect to the resulting or surviving corporation as he or she would have with respect to such constituent corporation if its separate existence had continued. For purposes of this Article VIII, references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to “serving at the request of the Corporation” shall include any service as a director, officer, employee or agent of the Corporation which imposes duties on, or involves services by, such director or officer with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner he or she reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the Corporation” as referred to in this Article VIII.

Section 11.    Survival of Indemnification and Advancement of Expenses. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article VIII shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer or employee and shall inure to the benefit of the heirs, executors and administrators of such a person.

Section 12.    Limitation on Indemnification. Notwithstanding anything contained in this Article VIII to the contrary, except for proceedings to enforce rights to indemnification (which shall be governed by Section 5 hereof), the Corporation shall not be obligated to indemnify any director, officer or employee in connection with a proceeding (or part thereof) initiated by such person unless such proceeding (or part thereof) was authorized or consented to by the Board of Directors of the Corporation.

Section 13.    Indemnification of Employees and Agents. The Corporation may, to the extent authorized from time to time by the Board of Directors, provide rights to indemnification and to the advancement of expenses to employees and agents of the Corporation similar to those conferred in this Article VIII to directors and officers of the Corporation.

Section 14.    Effect of Amendment or Repeal. Any repeal or modification of the foregoing provisions of this Article shall not adversely affect any right or protection hereunder of any person in respect of any act or admission occurring prior to the time of such repeal of modification.

ARTICLE IX

AMENDMENTS

Section 1.    Amendments. These Bylaws may be altered, amended or repealed, in whole or in part, or new Bylaws may be adopted by the stockholders or by the Board of Directors, provided, however, that notice of such alteration, amendment, repeal or adoption of new Bylaws be contained in the notice of such meeting of stockholders or Board of Directors as the case may be. Subject to the requirements of the Certificate of Incorporation, all such amendments must be approved by either the affirmative vote of the holders of at least 50% of the voting power of all the shares of capital stock of the Corporation then entitled to vote generally in the election of directors, voting together as a single class or by a majority of the entire Board of Directors then in office.

Section 2.    Entire Board of Directors. As used in this Article IX and in these Bylaws generally, the term “entire Board of Directors” means the total number of directors which the Corporation would have if there were no vacancies.
