ARTICLE IV

CAPITAL STOCK

4.1 CAPITAL STOCK. Shares may be issued by Eastern Bankshares, Inc. (the “CORPORATION”) from time to time by a vote of its Board of Directors without the approval of its shareholders. Upon payment of lawful consideration, such shares shall be deemed to be fully paid and nonassessable. In the case of a stock dividend, that part of the surplus of the Corporation which is transferred to stated capital upon the issuance of shares as a stock dividend shall be deemed to be the consideration for their issuance.

Shareholders shall have no preemptive rights except as may be provided expressly in any series of preferred stock.

A description of the different classes and series of the Corporation’s capital stock and a statement of the designations and the relative rights, preferences and limitations of the shares of each class and series of capital stock are as follows:

4.1.1. COMMON STOCK. Except as provided by law or in this Article IV (or in any supplemental section hereto or in any certificate of designation of any series of preferred stock) the holders of the common stock shall exclusively possess all voting power. Each holder of shares of common stock shall be entitled to one vote for each share held by such holder. There shall be no cumulative voting rights in the election of members of the Board of Directors of the Corporation (“DIRECTORS”) or other matter submitted to shareholders for vote.

Except as otherwise expressly provided in the resolutions or votes creating a series of preferred stock, or where (notwithstanding the provisions of these Articles) a separate class vote is conferred by law on any class or series of stock, the holders of common stock shall vote together with the holders of the preferred stock, if any, outstanding and entitled to vote, as one class.

If there shall have been paid, or declared and set aside for payment, to the holders of the outstanding shares of any class of stock having preference over the common stock as to the payment of dividends, the full amount of dividends and of a sinking fund or a retirement fund or other retirement payments, if any, to which such holders are respectively entitled in preference to the common stock, then dividends may be paid on the common stock and on any class or series of stock entitled to participate therewith as to dividends, out of any assets legally available for the payment of dividends, but only when and as declared by the Board of Directors.

A-1

In the event of any liquidation, dissolution or winding up of the Corporation, after there shall have been paid to or set aside for the holders of any class having preference over the common stock in the event of liquidation, dissolution or winding up of the Corporation the full preferential amounts to which they are respectively entitled and distributions or provision for distributions in settlement of the Liquidation Account established by the Corporation as described in Section 4.2 herein, the holders of the common stock, and of any class or series of stock entitled to participate in whole or in part therewith as to the distribution of assets, shall be entitled, after payment or provision for payment of all debts and liabilities of the Corporation, to receive the remaining assets of the Corporation available for distribution, in cash or in kind, in proportion to their holdings.

4.1.2 PREFERRED STOCK. The Board of Directors of the Corporation is authorized, by vote or votes from time to time adopted, to provide for the issuance of preferred stock in one or more series and to fix and state the voting powers, designations, preferences and relative participating, optional or other special rights of the shares of each series and the qualifications, limitations, and restrictions thereof, including, but not limited to, determination of one or more of the following:

A-2

Each share of each series of preferred stock shall have the same relative rights as and be identical in all respects with all the other shares of the same series. Subject to the authority of the Board of Directors as set forth in subsection (i) above, any shares of preferred stock shall, upon reacquisition thereof by the Corporation, be restored to the status of authorized but unissued preferred stock under this Section 4.1.2.

Except as specifically provided in these Articles, the holders of preferred stock or common stock shall not be entitled to any vote and shall not have any voting rights concerning the designation or issuance of any shares of preferred stock authorized by and complying with the conditions of these Articles, and subject to the authority of the Board of Directors or any authorized committee thereof as set forth above, the right to any such vote is expressly waived by all present and future holders of the capital stock of the Corporation.

Unless otherwise provided by law, any such vote shall become effective when the Corporation files with the Secretary of the Commonwealth of Massachusetts a certificate of designation of any one or more series of preferred stock signed by the President or any Vice President and by Secretary or Assistant Secretary of the Corporation, setting forth a copy of the vote of the Board of Directors establishing and designating the series and fixing and determining the relative rights and preferences thereof, the date of adoption of such vote and a certification that such vote was duly adopted by the Board of Directors.

4.2 LIQUIDATION ACCOUNT. Under regulations of Board of Governors of the Federal Reserve System and the Massachusetts Division of Banks, the Corporation must establish and maintain a liquidation account (the “LIQUIDATION ACCOUNT”) for the benefit of certain Eligible Account Holders and Supplemental Eligible Account

A-3

Holders as defined in the Plan of Conversion of Eastern Bank Corporation, as may be amended from time to time (the “PLAN OF CONVERSION”). In the event of a complete liquidation involving (i) the Corporation or (ii) Eastern Bank, the Corporation must comply with the regulations of the Board of Governors of the Federal Reserve System and the Massachusetts Division of Banks and the provisions of the Plan of Conversion with respect to the amount and priorities of each Eligible Account Holder’s and Supplemental Eligible Account Holder’s interests in the Liquidation Account. The interest of an Eligible Account Holder or Supplemental Eligible Account Holder in the Liquidation Account does not entitle such account holders to voting rights.

5.1. BENEFICIAL OWNERSHIP LIMITATION.

The provisions of this Section 5.1 shall become effective upon (i) the consummation of the conversion of Eastern Bank Corporation into stock holding company form (the “CONVERSION”) and (ii) the related public stock offering by the Corporation (the date on which the Conversion occurs being referred to as the “EFFECTIVE DATE”). Any capitalized term used but not otherwise defined in this Section 5.1 shall have the respective meaning set forth in Section 5.1.8.

5.1.2 PROHIBITIONS RELATING TO BENEFICIAL OWNERSHIP OF VOTING STOCK. No Person other than the Corporation, any Subsidiary or any pension, profit-sharing, stock bonus or other compensation plan maintained by the Corporation or any Subsidiary for the benefit of the employees of the Corporation or any Subsidiary (or any trust or custodial arrangement established in connection with any such plan) shall directly or indirectly offer to acquire or acquire the Beneficial Ownership of more than ten percent (10%) of the issued and outstanding Voting Shares (including any securities convertible into, or exercisable for, Voting Shares) if, after conversion or exercise by such Person of all such convertible or exercisable securities of which such Person is the Beneficial Owner, such Person would be the Beneficial Owner of more than ten percent (10%) of the issued and outstanding Voting Shares. Any Person so prohibited who directly or indirectly acquires or holds the Beneficial Ownership of more than ten percent (10%) of the issued and outstanding Voting Shares in violation of this Section 5.1.2 shall be subject to the provisions of Section 5.1.3 and Section 5.1.4 herein. The Corporation is authorized to refuse to recognize a transfer or attempted transfer of any Voting Shares to any Person who beneficially owns, or who the Corporation believes would become by virtue of such transfer the Beneficial Owner of, more than 10% of the Voting Shares.

5.1.3 EXCESS SHARES. If, notwithstanding the foregoing prohibition, a Person subject to the foregoing prohibition shall voluntarily or involuntarily become or attempt to become the purported Beneficial Owner (the “PURPORTED OWNER”) of Voting Shares in excess of 10% of the issued and outstanding Voting Shares, (i) during the period of three (3) years following the Effective Date (the “INITIAL PERIOD”), the number of shares in excess of ten percent (10%) shall be deemed to be “EXCESS SHARES,” and shall not be counted as shares entitled to vote, shall not be voted by any Person or counted as Voting Shares in connection with any matter submitted to the

B-1

shareholders for a vote, and shall not be counted as outstanding for purposes of determining the affirmative vote necessary to approve any matter submitted to the shareholders for a vote; or (ii) following the Initial Period, the holder of any Excess Shares shall be entitled to cast only one one-hundredth (1/100) of one vote per share for each Excess Share.

5.1.4 NOTATION ON CERTIFICATES. The restrictions set forth in this Article V shall be noted conspicuously on every certificate evidencing ownership of one or more Voting Shares.

5.1.5 POWERS OF THE BOARD OF DIRECTORS.

(a) The Board of Directors may, to the extent permitted by law, from time to time establish, modify, amend or rescind, by the Bylaws of the Corporation or otherwise, regulations and procedures not inconsistent with the express provisions of this Section 5.1 for the application, administration and implementation of the provisions of this Section 5.1.

(b) When it appears that a particular Person has become a Purported Owner of Excess Shares in violation of Section 5.1.2 and Section 5.1.3, or of the regulations or procedures of the Board of Directors with respect to this Section 5.1, and that the provisions of this Section 5.1 require application, interpretation or construction, then a majority of the Independent Directors (as defined in Section 6.1.4 of these Articles) shall have the power and duty to interpret all of the terms and provisions of this Section 5.1 and to determine on the basis of information known to them after reasonable inquiry all facts necessary to ascertain compliance with this Section 5.1, including, without limitation, (i) the number of Voting Shares beneficially owned by any Person or Purported Owner, (ii) whether a Person or Purported Owner is an Affiliate or Associate of, or is acting in concert with, any other Person or Purported Owner, (iii) whether a Person or Purported Owner has an agreement, arrangement or understanding with any other Person or Purported Owner as to the voting or disposition of any Voting Shares, (iv) the application of any other definition or operative provision of this Section 5.1 to the given facts or (v) any other matter relating to the applicability or effect of this Section 5.1.

(c) The Board of Directors, by the affirmative vote of a majority of the Independent Directors, shall have the right to demand that any Person who is reasonably believed to be a Purported Owner of Excess Shares (or who holds of record Voting Shares beneficially owned by any Person reasonably believed to be a Purported Owner in excess of such limit) supply the Corporation with information as to (x) the record owner(s) of all Voting Shares beneficially owned by such Person or Purported Owner and (y) any other factual matter relating to the applicability or effect of this Section 5.1 as may reasonably be requested of such Person or Purported Owner.

B-2

(d) Any applications, interpretations, constructions or any other determinations made by the Board of Directors pursuant to this Section 5.1, in good faith and on the basis of such information and assistance as was then reasonably available for such purpose, shall be conclusive and binding upon the Corporation and its shareholders, and no shareholder shall have the right to challenge any such application, interpretation, construction or determination.

5.1.6 SEVERABILITY. In the event any provision (or portion thereof) of this Section 5.1 shall be found to be invalid, prohibited or unenforceable for any reason, the remaining provisions (or portions thereof) of this Section 5.1 shall remain in full force and effect, and shall be construed as if such invalid, prohibited or unenforceable provision had been stricken herefrom or otherwise rendered inapplicable, it being the intent of this Corporation and its shareholders that each such remaining provision (or portion thereof) of this Section 5.1 remain, to the fullest extent permitted by law, applicable and enforceable as to all shareholders, including Purported Owners, if any, notwithstanding any such finding.

5.1.7 EXCLUSIONS. This Section 5.1 shall not apply to (a) any offer or sale with a view towards public resale made exclusively by the Corporation to any underwriter or underwriters acting on behalf of the Corporation, or to the selling group acting on such underwriter’s or underwriters’ behalf, in connection with a public offering of the common stock of the Corporation; or (b) any reclassification of securities (including any reverse stock split), or recapitalization of the Corporation, or any merger or consolidation of the Corporation with any of its Subsidiaries or any other transaction or reorganization that does not have the effect, directly or indirectly, of changing the Beneficial Ownership interests of the Corporation’s shareholders, other than pursuant to the exercise of any dissenters’ appraisal rights, except as a result of immaterial changes due to fractional share adjustments, which changes do not exceed, in the aggregate, one percent (1%) of the issued and outstanding shares of such class of equity or convertible securities.

(3) The holders of all outstanding Voting Shares not beneficially owned by the Interested Shareholder immediately prior to the consummation of any Business Combination shall be entitled to receive in such Business Combination cash or other consideration for their shares meeting all of the terms and conditions of this Section 6.1.3(b); provided, however, that the failure of any shareholders who are exercising their statutory rights to dissent from such Business Combination and receive payment of the fair value of their shares to exchange their shares in such Business Combination shall not be deemed to have prevented the condition set forth in this Section 6.1.3(b)(3) from being satisfied.

C-3

(4) The consideration to be received by holders of any particular class or, if outstanding, any particular series of outstanding Voting Shares (including Common Shares) shall be in cash or in the same form as the Interested Shareholder or any of its Affiliates has previously paid for shares of such class or series of Voting Shares.

(7) After such Interested Shareholder has become an Interested Shareholder, such Interested Shareholder shall not have received the benefit, directly or indirectly (except proportionately as a shareholder), of any loans, advances, guarantees, pledges or other financial assistance or any tax credits or other tax advantages provided, directly or indirectly, by the Corporation, whether in anticipation of or in connection with such Business Combination or otherwise.

(1) is the Beneficial Owner, directly or indirectly, of ten percent (10%) or more of the voting power of the outstanding Voting Shares; or

(2) is an Affiliate of the Corporation and at any time within the two-year period immediately prior to the date in question was the Beneficial Owner, directly or indirectly, of ten percent (10%) or more of the voting power of the then outstanding Voting Shares; or

(3) is an assignee of or has otherwise succeeded to any Voting Shares which were at any time within the two-year period immediately prior to the date in question beneficially owned by any Interested Shareholder, if such assignment or succession shall have occurred in the course of a transaction or series of transactions not involving a public offering within the meaning of the Securities Act of 1933, as amended, and such assignment or succession was not approved by two-thirds (2/3) of the Independent Directors.

(h) SUBSIDIARY. As used in this Section 6.1, “SUBSIDIARY” shall have the meaning set forth in Section 5.1.8(d) of these Articles; provided, however, that for the purposes of the exclusion from the definition of Interested Shareholder set forth in Section 6.1.4(g), the term “Subsidiary” shall mean only a corporation of which a majority of each class of equity security is owned, directly or indirectly, by the Corporation.

6.1.5 POWERS OF THE BOARD OF DIRECTORS. A majority of the Independent Directors of the Corporation then in office shall have the power and duty to determine for the purposes of this Section 6.1, on the basis of information known to them after reasonable inquiry (a) whether a Person is an Interested Shareholder; (b) the number or percentage of Voting Shares Beneficially Owned by any Person; (c) whether a Person is an Affiliate or Associate of another; (d) whether the assets which are the subject of any Business Combination have, or the consideration to be received for the issuance or transfer of securities by the Corporation or any Subsidiary in any Business Combination has, an aggregate Fair Market Value equal to or greater than ten percent (10%) of the combined assets of the Corporation and its Subsidiaries; (e) whether the requirements of Section 6.1.3 have been met with respect to any Business Combination; and (f) any other matters of interpretation arising under this Section 6.1. The good faith determination of a majority of the Independent Directors on such matters shall be conclusive and binding for all purposes of this Section 6.1.

C-7

6.1.6 NO EFFECT ON FIDUCIARY OBLIGATIONS OF INTERESTED SHAREHOLDERS. Nothing contained in this Section 6.1 shall be construed to relieve any Interested Shareholder from any fiduciary obligation imposed by law.

6.1.7 AMENDMENT, REPEAL, ETC. Notwithstanding any other provisions of these Articles or the Bylaws of the Corporation (and notwithstanding the fact that a lesser percentage or no vote may be specified by law, these Articles or the Bylaws of the Corporation), and in addition to any affirmative vote of the holders of or any other class or series of capital stock of the Corporation or any series of the foregoing then outstanding which is required by law or by or pursuant to these Articles, and the requirement of Section 6.6 that any amendment to these Articles be approved by the Board of Directors, the affirmative vote of the holders of a majority of the Voting Shares not beneficially owned by the Interested Shareholder, voting together as a single voting group, shall be required to amend, repeal, or adopt any provisions inconsistent with, this Section 6.1, if at the time such action is taken there is an Interested Shareholder.

6.2. SHAREHOLDER ACTION GENERALLY. Any action to be taken by the shareholders of the Corporation may be effected at a duly called annual or special meeting of shareholders of the Corporation or by the unanimous consent in writing of all shareholders entitled to vote on the action.

6.3. SHAREHOLDER VOTE REQUIRED FOR CERTAIN TRANSACTIONS. Subject to the provisions of Section 6.1 and in addition to any affirmative vote required by the Act or these Articles, any (i) sale, lease or exchange of all or substantially all of the property or assets, including goodwill, of the Corporation, or (ii) merger, share exchange or consolidation of the Corporation with or into any other entity, shall, to the extent approval by the Corporation’s shareholders is required by applicable law or by these Articles, require the affirmative vote of at least two-thirds (2/3) of the total number of votes eligible to be cast by shareholders on such sale, lease or exchange, or merger, share exchange or consolidation, voting together as a single voting group, at a duly constituted meeting of shareholders called expressly for such purpose. The two-thirds (2/3) vote requirement set forth in the previous sentence shall not apply, and only the affirmative vote of a majority of the total number of votes eligible to be cast by shareholders on such matter, voting together as a single voting group, shall be required if the Board of Directors recommends, by the affirmative vote of two-thirds (2/3) of the Directors then in office at a duly constituted meeting of the Board of Directors (unless at the time of such action there shall be an Interested Shareholder, in which case such action shall also require the affirmative vote of a majority of the Independent Directors then in office at such meeting), that the shareholders approve such transaction by the affirmative vote of a majority of the total votes eligible to be cast by shareholders on such transaction, voting together as a single voting group. The provisions of this Section 6.4 shall not apply to the extent that a higher percentage vote shall be required by law or the provisions of Section 6.1 of these Articles.

6.4. DIRECTORS.

6.4.1 AUTHORITY OF BOARD OF DIRECTORS. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors.

C-8

In addition to the powers and authority expressly conferred upon them by statute or by these Articles or the Bylaws of the Corporation, the Directors are hereby empowered to exercise all such powers and do all such acts and things as may be exercised or done by the Corporation.

6.4.2. STANDARDS FOR BOARD OF DIRECTORS’ ACTIONS. Members of the Board of Directors of the Corporation, in considering what they reasonably believe to be in the best interests of the Corporation, may consider the interests of the Corporation’s employees, suppliers, creditors and customers, the economy of the state, the region and the nation, community and societal considerations, and the long-term and short-term interests of the Corporation and its shareholders, including the possibility that these interests may be best served by the continued independence of the Corporation.

6.4.3 CLASSIFICATION OF DIRECTORS. The number of Directors and their respective classifications shall be fixed from time to time by the Board of Directors; provided, however, that if at the time of such action there is an Interested Shareholder, such action shall in addition require the affirmative vote of a majority of the Independent Directors then in office. The Directors, other than those who may be elected by the holders of any other class or series of shares of the Corporation with a separate right to elect Directors, shall be classified, with respect to the term for which they severally hold office, into three classes, as nearly equal in number as possible, with one class to be elected annually. At each annual meeting of shareholders, the successors of the class of Directors whose term expires at that meeting shall be elected at such meeting to hold office for a term expiring at the annual meeting of shareholders held in the third year following the year of their election, provided, however, that during the time necessary to accomplish the classification of directors, one class of Directors may be elected for a term of one year and one class of Directors may be elected for a term of two (2) years. Members of each class shall hold office until the annual meeting occurring at the end of their respective terms, or until such Director sooner dies, resigns, is removed or becomes disqualified. Despite the expiration of a Director’s term, such Director shall continue to serve until his or her successor is duly elected and qualified or until the number of Directors has been reduced. Subject to the rights of the holders of any series of preferred stock then outstanding and except as otherwise required by applicable law, any and all vacancies in the Board of Directors, however occurring including, without limitation, by reason of an increase in size of the Board of Directors, or the death, resignation, disqualification or removal of a Director, shall be filled solely and exclusively by the affirmative vote of a majority of the remaining Independent Directors then in office, even though less than a quorum. A vacancy that will occur at a specific later date may be filled before the vacancy occurs, but the new Director may not take office until the vacancy occurs. Directors so chosen shall hold office for a term expiring at the annual meeting of shareholders at which the term of office of the class to which they have been chosen expires. A decrease in the number of Directors shall not shorten any incumbent Director’s term.

C-9

6.4.4 ELECTION OF DIRECTORS. At each meeting of shareholders at which directors are elected, the successors of the Directors whose term expires at that meeting shall be elected by a plurality vote of all votes cast at such meeting, unless a greater vote then is required by the Bylaws of this Corporation. For purposes of clarity, “abstentions,” “withheld” votes and “broker non-votes” shall not be counted as a vote cast with respect to such action.

6.4.5 REMOVAL OF DIRECTORS. Subject to the rights of any voting group with a separate right to elect Directors, any Director (including any Person elected by the Board of Directors to fill any vacancy in the Board of Directors) may be removed from office only for cause and only by either (i) the affirmative vote of at least two-thirds (2/3) of the Independent Directors then in office at a duly constituted meeting of the Board of Directors or (ii) an affirmative a majority of the total votes eligible to be cast by shareholders, voting together as a single class, at a duly constituted meeting of shareholders called expressly for the purpose of removing such Director, and the meeting notice must state that the purpose, or one of the purposes, of the meeting is removal of the Director. As used in this Section, the term “CAUSE” shall have the meaning set forth in Section 8.06(f)(2) of the Act.

6.4.6 LIMITATION OF LIABILITY OF DIRECTORS. No Director of the Corporation shall have personal liability to the Corporation or its shareholders for monetary damages for breach of his or her fiduciary duty as a Director notwithstanding any provision of law imposing such liability, provided that this provision shall not eliminate or limit the liability of a director (a) for any breach of the director’s duty of loyalty to the corporation or its shareholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) for improper distributions under Section 6.40 of the Act, or (d) for any transaction from which the director derived an improper personal benefit; and provided, further, however, that the Corporation shall not make any indemnification payment prohibited by Section 18(k) of the Federal Deposit Insurance Act or the regulations promulgated thereunder by the Federal Deposit Insurance Corporation. No amendment to or repeal of the provisions of this paragraph shall apply to or have any effect on the liability or alleged liability of any director of the Corporation for or with respect to any act or failure to act of such director occurring prior to such amendment or repeal. If the General Laws of Massachusetts are hereafter amended to further eliminate or limit the personal liability of Directors or to authorize corporate action to further eliminate or limit such liability, then the liability of the Directors of this Corporation shall be eliminated or limited to the fullest extent then permitted by the General Laws of Massachusetts as so amended.

6.5. AMENDMENT OF BYLAWS.

6.5.1 AMENDMENT BY DIRECTORS. Except as otherwise required by law, the Board of Directors may adopt, amend or repeal the Bylaws of this Corporation in whole or in part, acting by the affirmative vote of a majority of the Directors then in office at a duly constituted meeting of the Board of Directors (unless at the time of such action there shall be an Interested Shareholder, in which case such action shall also

C-10

require the affirmative vote of at least two-thirds (2/3) of the Independent Directors then in office at such meeting). Not later than the time of giving notice of the annual meeting of shareholders next following the adoption, amendment or repeal by the Directors of any Bylaw, notice thereof stating the substance of such action shall be given to all shareholders entitled to vote on amending the Bylaws of this Corporation.

6.5.2 AMENDMENT BY SHAREHOLDERS. The Bylaws of the Corporation may be amended at a duly constituted meeting of shareholders, called expressly for such purpose, by the affirmative vote of a majority of the total votes eligible to be cast by shareholders on such amendment, voting together as a single voting group.

6.6. AMENDMENT OF ARTICLES OF ORGANIZATION. These Articles may be amended by the Board of Directors without shareholder action to the fullest extent permitted by the Act. Except as otherwise expressly required by law with respect to the right of any voting group to vote separately on an amendment to these Articles, and except as otherwise required by Section 6.1.7 of these Articles, these Articles may also be amended, at a duly constituted meeting of shareholders called expressly for such purpose, by the affirmative vote of a majority of the total votes eligible to be cast by shareholders on such amendment, voting together as a single voting group, provided that such amendment has been duly approved by the Board of Directors with the affirmative vote of a majority of directors.

6.7. INTERPRETATION. When a reference is made in these Articles to a Section, such reference unless the context expressly provides otherwise shall refer to a Section of these Articles, and any such reference shall include all subsections, which are part of the related Section (e.g., a section numbered “6.5.1” would be part of “6.5” and references to “Section 6.5” would also refer to material contained in the subsection described as “Section 6.5.1”). The headings contained in these Articles are for reference purposes only and shall not affect in any way the meaning or interpretation of these Articles.

6.8.3 EXCLUSIVE JURISDICTION IN FEDERAL COURTS. This Section 6.8 shall not apply to any claim for which the federal courts have exclusive jurisdiction, including, to the extent applicable, any claim brought to enforce any liability or duty created by the Securities Exchange Act of 1934 or the rules and regulations thereunder.

6.8.4 CONSENT TO FORUM. Any person or entity purchasing or otherwise acquiring or holding any interest in shares of capital stock of the Corporation (including a beneficial owner of such capital stock) shall be deemed to have notice of and consented to the provisions of this Section 6.8.

If any provision or provisions of this Section 6.8 shall be held to be invalid, illegal or unenforceable as applied to any person or entity or circumstance for any reason whatsoever, then, to the fullest extent permitted by law, the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Section 6.8 (including, without limitation, each portion of any sentence of this Section 6.8 containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) and the application of such provision to other persons or entities and circumstances shall not in any way be affected or impaired thereby.
