        7.1.2.    Not void or voidable if:    No conflicting interest transaction shall be void or voidable, be enjoined, be
set aside, or give rise to an award of damages or other sanction in a proceeding by a shareholder or by or in the right of the corporation, solely because the conflicting interest transaction involves
a director of the corporation or an entity in which a director of the corporation is a director of officer or has a financial interest, or solely because the director is present at or participates in
the meeting of the corporation's board of directors or of the committee of the board of directors which authorizes, approves or ratifies a conflicting interest transaction, or solely because the
director's vote is counted for such purpose if: 



        (a)   the
material facts as to the director's relationship or interest and as to the conflicting interest transaction are disclosed or are known to the board of directors or
the committee, and the board of directors or committee in good faith authorizes, approves or ratifies the conflicting interest transaction by the affirmative vote of a majority of the disinterested
directors, even though the disinterested directors are less than a quorum; or 


        (b)   the
material facts as to the director's relationship or interest and as to the conflicting interest transaction are disclosed or are known to the shareholders entitled
to vote thereon, and the conflicting interest transaction is specifically authorized, approved or ratified in good faith by a vote of the shareholders; or 



        (c)   a
conflicting interest transaction is fair as to the corporation as of the time it is authorized, approved or ratified by the board of directors, a committee thereof, or
the shareholders. 




        7.1.3.    Interested Directors as Part of Quorum.    Common or interested directors may be counted in determining the
presence of a quorum at a meeting of the board of directors or of a committee which authorizes, approves or ratifies the conflicting interest transaction. 



        7.1.4.    Notice to Shareholders Required for Loan to Director.    Neither the board of directors nor any committee
thereof shall authorize a loan by the corporation to a director of the corporation or to an entity in which a director of the corporation is a director or officer or has a financial interest, or
guaranty by the corporation of an obligation of a director of the corporation or of an obligation of an entity in which a director of the corporation is a director or officer or has a financial
interest, until at least ten days after written notice of the proposed authorization of the loan or guaranty has been given to the shareholders who would be entitled to vote thereon if the issue of
the loan or guaranty were submitted to a vote of the shareholders. The requirements of this Section 7.1.4 are in addition to, and not in substitution for, the provision of Sections 7.1.1
through 7.1.3. 




        7.2.    Limitation on Director's Liability.    



        7.2.1.    Maximum Limitation Permitted by Law.    To the fullest extent permitted by the Act, as the same exists or
may hereafter be amended, a director of the corporation shall not be personally liable to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director, except
that this provision shall not eliminate or limit the liability of a director to the corporation or to its shareholders for monetary damages otherwise existing for: 



        (a)   any
breach of the director's duty of loyalty to the corporation or to its shareholders; 


        (b)   acts
or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; 


        (c)   voting
for or assenting to a distribution in violation of sections 7-106-401 and 7-108-403 of the Act or the articles of
incorporation if it is established that the director did not perform that director's duties in compliance with section 7-108-401 of the Act, provided that the personal
liability of a director in this circumstance shall be limited to the amount of

the
distribution which exceeds the amount or value of the distribution which could have been distributed without violation of sections 7-106-401 and
7-108-403 of the Act or the articles of incorporation; or 


        (d)   any
transaction from which the director directly or indirectly derives any improper personal benefit. 




        7.2.2.    Defenses and Rights to Contribution.    Nothing contained herein will be construed to deprive any director
of that director's right to all defenses ordinarily available to a director nor will anything herein be construed to deprive any director of any right he may have for contribution from any other
director or other person. 


        7.2.3.    Amendment to Statute.    If the Act is hereafter amended to eliminate or limit further the liability of a
director, then, in addition to the elimination and limitation of liability provided by the preceding sentence, the liability of each director shall be eliminated or limited to the fullest extent
permitted by the Act as so amended. Any repeal or modification of this Article by the shareholders of the corporation shall be prospective only and shall not adversely affect any right or protection
of a director of the corporation existing at the time of such repeal or modification. 




        7.3    Indemnification.    The corporation shall indemnify, to the maximum extent permitted by law, any person who is
or was a director, officer, agent, fiduciary or employee of the corporation against any claim, liability or expense arising against or incurred by such person made a party to a proceeding because that
person is or was a director, officer, agent, fiduciary or employee of the corporation or because that person is or was serving another entity as a director, officer, partner, trustee, employee,
fiduciary or agent at the corporation's request. The corporation shall further have the authority to the maximum extent permitted by law to purchase and maintain insurance providing such
indemnification. 


        7.4    No Equitable Interests in Shares or Rights.    Unless a person is recognized as a shareholder through
procedures established by the corporation pursuant to section 7-107-204 of the Act or any similar law, the corporation shall be entitled to treat the registered holder
of any shares of the corporation as the owner thereof for all purposes permitted by the Act, including without limitation all rights deriving from such shares, and the corporation shall not be bound
to recognize any equitable or other claim to, or interest in, such shares or rights deriving from such shares on the part of any other person including without limitation, a purchaser, assignee or
transferee of such shares, unless and until such other person becomes the registered holder of such shares or is recognized as such, whether or not the corporation shall have either actual or
constructive notice of the claimed interest of such other person. By way of example and not of limitation, until such other person has become the registered holder of such shares or is recognized
pursuant to section 7-107-204 of the Act or any similar applicable law, such person shall not be entitled: (i) to receive notice of the meetings of the
shareholders; (ii) to vote at such meetings; (iii) to examine a list of the shareholders; (iv) to be paid dividends or other distributions payable to shareholders; or
(v) to own, enjoy and exercise any other rights deriving from such shares against the corporation. Nothing contained herein will be construed to deprive any beneficial shareholder, as defined
in section 7-113-101(1) of the Act, of any right such shareholder may have pursuant to Article 113 of the Act or any subsequent law.
