The shareholders shall meet such qualifications as may be established by the Board of Directors from time to time, provided that shares shall only be issued to persons licensed by the Colorado State Board of Medical Examiners to practice medicine without restrictions in the State of Colorado and otherwise meeting the qualifications of shareholders as set forth in the Articles and approved to be a shareholder in accordance with the terms of these Bylaws.

1.2 Place of Meetings. Shareholders’ meetings shall be held at the principal office of the Corporation or at such other place, either within or without the State of Colorado, as the Board of Directors may designate or as may be specified in the call of the meeting. A waiver of notice signed by all shareholders entitled to vote at a meeting may designate any place, either within or outside Colorado, as the place for such meeting.

1.3 Annual Meeting. The annual meeting of the shareholders shall be held on such date and at such time and place as the Board of Directors may designate. At said annual meeting, the shareholders shall elect the directors as prescribed herein. The shareholders shall transact such other business as shall properly come before the meeting.

1.4 Special Meetings. The Corporation shall hold a special shareholders’ meeting if called by the Board of Directors or in the event the Corporation receives one or more written demands for the meeting, stating the purpose or purposes for which it is to be held, signed and dated by the holders of shares representing’ not less than one-tenth of all of the votes entitled to be cast on any issue at the meeting. The special meeting shall be held at the principal office of the Corporation or at such other place as the Board of Directors or the president may determine.

1.5 Notice of Meetings. Written notice stating the place, date and hour of the meeting shall be given not less than 5 nor more than 60 days prior to the date of the meeting, (except that, if the Articles are to be amended to increase the number of authorized shares, at least 30 days notice shall be given) and, in case of a special meeting, or where a purpose of the meeting is to consider an amendment to the Articles, a restatement of the Articles, a plan of merger or share exchange, disposition of substantially all, of the property of the Corporation, consent by the Corporation to the disposition of property by another entity or dissolution of the Corporation, such notice shall include a description of the purpose for which the meeting is called. Notice shall be given personally or by mail, private carrier, electronically transmitted facsimile or other form of communication by or at the direction of the president, the secretary/treasurer, or the officer or persons calling the meeting, to each shareholder of record entitled to vote at such meeting. If mailed, such notice shall be deemed to be given and effective when deposited in the United States mail, properly addressed to the shareholder at his address as it appears in the

Corporation’s current record of shareholders, with first class postage prepaid. If notice is given other than by mail, and provided that such notice is in a comprehensible form, the notice is given and effective on the date actually received by the shareholder.

1.6 Waiver of Notice. A shareholder may waive any notice required to be given by these Bylaws, the Articles or the Colorado Business Corporation Act, whether before or after the date or time of the meeting stated in the notice. A waiver shall be in writing, signed by the shareholder entitled to the notice, and shall be delivered to the Corporation for inclusion in the minutes or filing with the corporate records, but such delivery and filing shall not be conditions of the effectiveness of the waiver. Attendance by a shareholder at any regular or special meeting shall be deemed the equivalent of a waiver in writing by such shareholder of notice of such meeting, unless the shareholder objects at the beginning of the meeting to holding the meeting because of the lack of notice or defective notice, or consideration of a matter at a meeting that is not within the purpose or purposes described in the meeting notice, unless the shareholder objects to considering the matter when it is presented at the meeting.

1.7 Determination of Shareholders. For the purpose of determining shareholders (1) entitled to notice of or to vote at any meeting of shareholders or any adjournment thereof, (2) entitled to demand a special shareholders’ meeting, (3) entitled to take any other action, (4) entitled to receive payment of a share dividend or a distribution or (5) for any other proper purpose, the Board of Directors may fix a future date as the record date for such determination of shareholders. The record date may be fixed not more than 70 days and, in the case of a meeting of shareholders, not less than 10 days prior to the date of the proposed action. Unless otherwise specified when the record date is fixed, the time of day for determination of shareholders shall be as of the Corporation’s close of business on the record day. A determination of shareholders entitled to be given notice of or to vote at a shareholders’ meeting is effective for any adjournment of the meeting unless the Board of Directors fixes a new record date, which the board shall do if the meeting is adjourned to a date more than 120 days after the date fixed for the original meeting. If no record date is otherwise fixed, the record date for determining shareholders entitled to be given notice of and to vote at an annual or special shareholders’ meeting is the day before the first notice is given to shareholders. The record date for determining shareholders entitled to take action without a meeting is the date a writing upon which the action is taken is first received by the Corporation. The record date for determining shareholders entitled to a distribution shall be the date the Board of Directors authorizes the distribution.

1.8 Voting List. After a record date is fixed for a shareholders’ meeting, the Secretary/Treasurer shall prepare a list of the names of all its shareholders who are entitled to be given notice of the meeting. The list shall be alphabetical and shall show the address of and the number of shares that are held by each shareholder. The shareholders’ list shall be available for inspection by any shareholder, beginning the earlier of 10 days before the meeting for which the list was prepared or two business days after notice of the meeting is given and continuing through the meeting, and any adjournment thereof, at the Corporation’s principal office or at a place identified in the notice of the meeting in the city where the meeting will be held. A shareholder or an agent or attorney of the shareholder is entitled on written demand to inspect and, subject to the restrictions in the Colorado Business Corporation Act, copy the list during regular business hours and during the inspection period. The secretary/treasurer shall make the shareholders’ list available at the meeting, and any shareholder or agent or attorney of a shareholder is entitled to inspect the list at any time during the meeting or any adjournment.

1.9 Proxies. Voting by proxy by the shareholders shall be permitted. An appointment of a proxy is not effective against the Corporation until the appointment is received by the Corporation. An appointment is valid for 11 months, unless a different period is expressly provided in the appointment form. The Corporation may accept or reject any appointment of a proxy, revocation of appointment of a proxy, vote, consent, waiver, or other writing purportedly signed by or for a shareholder if such acceptance or rejection is in accordance with the provisions of Sections 7-107-203 and 7-107-205 of the Colorado Business Corporation Act.

1.10 Quorum. A quorum of shareholders at any meeting of shareholders shall consist of a majority of the votes entitled to be cast on the matter by the shareholders represented in person or by proxy. If a quorum does not exist, the president or any shareholder or proxy that is present at the meeting may adjourn the meeting without further notice to a different date, time, or place for a period not to exceed 120 days for any one adjournment, provided the new time, date, or place is announced at the meeting before adjournment. If a new record date must be set pursuant to Section 1.7 hereof, notice of the new meeting must be given pursuant to Section 1.5 hereof. At any reconvened meeting at which a quorum exists, any matter may be acted upon that could have been acted upon at the meeting originally called. Once a share is represented for any purpose at a meeting, including the purpose of determining that a quorum exists, it is deemed present for quorum purposes for the remainder of the meeting and for any adjournment of that meeting unless a new record date is or shall be set for that adjourned meeting.

1.11 Vote. If a quorum is present at a duly held meeting, the affirmative vote of a majority of all of the shares entitled to vote on the subject matter shall be the act of the shareholders, unless the vote of a greater proportion is required by law, the Articles, or these Bylaws.

1.12 Voting Trusts or Agreements. Shareholders may not enter into voting trust agreements. A voting agreement between shareholders is valid only if voting power remains with each participating shareholder of the Corporation.

1.13 Meetings by Electronic Communication. Any and all of the shareholders may participate in an annual or special shareholders’ meeting by, or the meeting may be conducted through the use of, any means of communication by which all persons participating in the meeting may hear each other during the meeting. A shareholder participating in a meeting by this means is deemed to be present in person at the meeting.

Written Consent in Lieu of Meeting

Any action required by Colorado Statutes, the Articles or these Bylaws to be taken at a meeting of the shareholders or directors of the Corporation, respectively, or any action which may be taken at a meeting of the shareholders or directors, may be taken without a meeting if a

consent in writing, setting forth the action so taken, shall be signed by all of the shareholders or directors entitled to vote with respect to the subject matter thereof, Action taken pursuant to this section shall be effective when the Corporation has received writings that describe and consent to the action, signed by all of the shareholders or directors entitled to vote thereon.

All certificates for shares shall be consecutively numbered or otherwise identified. The name and address of the shareholders, the number of shares and date of issue shall be entered on the stock transfer books of the Corporation.

6.3 Holder of Record. The Corporation shall be entitled to treat the registered holder of any shares of the Corporation as the owner thereof for all purposes, including all rights deriving from such shares, and 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, but not limited to, a purchaser, assignee or transferee of shares or rights deriving from shares, unless and until the purchaser, assignee, transferee or other person becomes the registered holder of the shares, whether or not the Corporation shall have either actual or constructive notice of the interest of such purchaser, assignee or transferee of any of the shares.

In addition to all other restrictions established by the Corporation’s Articles, these Bylaws, or any other agreement, no Transfer of shares shall be made unless the transferee is the Corporation or a person licensed by the State Board of Medical Examiners to practice medicine in the State of Colorado and who will actively practice medicine in the offices of the Corporation in accordance with the requirements set forth in the Articles. Any purported Transfer in violation of these Bylaws shall be void and ineffectual and shall not operate to transfer any interest or title in the purported transferee.

Restrictions upon transfers so imposed shall be evidenced by an appropriate notation upon the face of the certificate or certificates representing such restricted shares, in compliance with law, or, in the case of shares which are issued by the Corporation without certificates by an appropriate notation in the stock transfer records of the Corporation, and a complete and true copy of all restrictions so imposed shall be available for inspection by parties entitled thereto at the principal office of the Corporation during reasonable business hours. Nothing herein shall be deemed to invalidate any agreement between shareholders restricting transfer of their shares, which agreement is otherwise in accordance with law.
