     SECTION 1.  Annual Meetings. The corporation shall hold an annual meeting 
                 ---------------
of its stockholders for the election of directors and for the transaction of 
general business at such place as may be designated by the Board of Directors, 
at 3:00 p.m., on the second Saturday in April of each year, if not a legal 
holiday, and if a legal holiday, then on the first day following which is not a 
legal holiday. Such annual meetings shall be general meetings open for the 
transaction of any business within the powers of the corporation without special
notice of such business, except in cases in which special notice is required by 
statute, by the articles of incorporation or by these by-laws.

     SECTION 2.  Special Meetings. Unless otherwise prescribed by statute, 
                 ----------------
special meetings of the stockholders may be called at any time by the Board of 
Directors or by the President and shall be called by the President or the 
Secretary upon a written request of stockholders owning a twenty-five per cent 
(25%) interest in amount of the entire outstanding shares of the corporation 
entitled to vote. No business other than that stated in the notice described in 
the next succeeding section shall be transacted at any special meeting without 
the unanimous consent of all of the stockholders entitled to vote thereat.

     SECTION 3.  Notice of Meetings. Except as otherwise provided by law, 
                 ------------------
written or printed notice stating the place, date and hour of the meeting and, 
in case of a special meeting, a brief statement of the purpose or purposes for 
which the meeting is called, shall be delivered not less than ten (10) nor more 
than forty (40) days before the date of every meeting of stockholders either 
personally or by mail, by or at the direction of the President or the Secretary,
to each stockholder of record entitled to vote at such meeting. If mailed, such 
notice shall be deemed to be delivered when deposited in the United States mail 
addressed to the stockholder at his address as it appears on the records of the 
corporation, with postage thereon prepaid. Whenever any notice is required to be
given under the provisions of Illinois law, the articles of incorporation or 
these by-laws, a waiver thereof in writing signed by the person or persons 
entitled to such notice, whether it be before or after the time stated therein, 
shall


 
be deemed equivalent to the giving of such notice. It shall not be requisite to 
the validity of any meeting of stockholders that notice thereof, whether 
prescribed by law, by the articles of incorporation or by these by-laws, shall 
have been given to any stockholder who attends in person or by proxy. No notice 
other than by verbal announcement need be given of any adjourned meetings of 
stockholders.

     SECTION 4.  Place of Meetings. Annual and special meetings of stockholders 
                 -----------------
shall be held at one of the corporation's offices or at such place or places as 
shall be fixed by the Board of Directors.

     SECTION 5.  Quorum. Except as otherwise required by law, the articles of 
                 ------
incorporation or these by-laws, the presence, in person or by proxy, of 
stockholders holding a majority of the stock of the corporation entitled to vote
shall constitute a quorum at all meetings of the stockholders. In case a quorum 
shall not be present at any meeting, a majority in interest of the stockholders 
entitled to vote thereat, present in person or by proxy, shall have power to 
adjourn the meeting from time to time, without notice other than announcement at
the meeting, until the requisite amount of stock entitled to vote shall be 
present. If upon the reconvening of any such adjourned meeting a majority of the
stock entitled to vote shall be represented, any business may be transacted 
which might have been transacted at the meeting as originally noticed, but only 
those stockholders entitled to vote at the meeting as originally noticed shall 
be entitled to vote at such time as it is reconvened.

     SECTION 6.  Voting. Except when cumulative voting is required by law, each 
                 ------
outstanding share of the capital stock shall be entitled to one (1) vote on each
matter submitted to a vote at a meeting of stockholders. Shares of its own stock
belonging to the corporation shall not be voted, directly or indirectly, at any 
meeting and shall not be counted in determining the total number of outstanding 
shares at any given time, but shares of its own stock held by it in fiduciary 
capacity may be voted and shall be counted in determining the total number of 
outstanding shares at any given time. When a quorum is present or represented at
any meeting of stockholders, the vote of the holders of a majority of the shares
present in person or represented by proxy shall decide any question brought 
before such meeting, unless the question is one upon which a different vote is 
required by virtue of an express provision of law, the articles of incorporation
or another section of these by-laws.

     SECTION 7.  Proxies. Any stockholder entitled to vote at a meeting of 
                 -------
stockholders may vote either in person or by proxy executed in 

                                       2

 
writing by the stockholder or by his duly authorized attorney-in-fact; provided,
however, that no proxy to vote any shares of the corporation shall issue to or 
be voted by any person who is licensed pursuant to the Illinois Medical Practice
Act.

          SECTION 8. Action without Meeting. Whenever the vote of stockholders 
                     ----------------------
at a meeting thereof is required or permitted to be taken in connection with any
corporate action by any provisions of a statute, the articles of incorporation 
or of these by-laws, the meeting and vote of stockholders may be dispensed with 
if all the stockholders who would have been entitled to vote upon the action if 
such meeting were held shall consent in writing to such corporate action being  
taken.

          SECTION 9. List of Stockholders. At least ten (10) days prior to each 
                     --------------------
meeting of stockholders at which directors are to be elected, the Secretary 
shall make or cause to be made a complete list of the stockholders entitled to 
vote at the ensuing election, arranged in alphabetical order, showing the
mailing address of each according to the records of the corporation and the
number of voting shares held by each. Such list, for a period of ten (10) days
prior to such meeting, shall be kept on file at the registered office of the
corporation, and shall at all times during the usual hours for business be open
to the examination of any stockholder, and shall also be produced and kept at
the time and place of such election for the inspection of any stockholder during
the whole time thereof.

          The original stock ledger or transfer book, or a duplicate thereof, 
kept at the principal office of the corporation, shall be prima facie evidence 
as to who are the stockholders entitled to examine such list or stock ledger or 
transfer book or to vote at any meeting of stockholders.

corporation except such as are by statute, the articles of incorporation or
these by-laws conferred upon or reserved to the stockholders. Continuing and
exclusive authority to fix, supervise and control the professional, business and
other affairs of the corporation shall be

wholly vested in the Board of Directors.

          SECTION 2. Number. The number of directors shall be three except that 
                     ------
in cases where all of the shares of the corporation are owned beneficially and 
of record by either one (1) or two (2) stockholders, the stockholders by 
resolution at an annual or special meeting may fix the number of directors to be
less than three (3) but not less than the number of stockholders. The directors

the Illinois Medical Practice Act.

          SECTION 3. Election and Term. The directors shall be elected at the 
                     -----------------

and place of such meeting may be fixed by consent in writing of all the 
directors.

          Regular meetings of the Board of Directors may be held without notice 
at such places and times as shall be determined from time to time by resolution
of the directors. Unless otherwise determined as aforesaid, regular meetings

alternative, upon two (2) days' notice, by mailing it, postage prepaid, and 
addressed to him at his last known mailing address, as reflected in the records 
of the corporation. It shall not be requisite to the validity of any meeting of 
the Board of Directors that notice thereof shall have been given to any director
who attends, except where a director attends for the express purpose of 
objecting to the

                                       4


 
transaction of any business because the meeting is not lawfully called or 
convened. No notice of adjourned meetings of the Board of Directors need be 
specified in the notice or waiver of notice of such meeting. All regular and 
special meetings of the Board of Directors shall be open for the transaction of 
any business within the powers of the corporation without special notice of
such business, except in those cases in which special notice is required by law,
the articles of incorporation or by these by-laws.

          SECTION 6. Quorum. At all meetings of the Board of Directors, a 
                     ------
majority of the Board of Directors shall constitute a quorum for the transaction

which a quorum is present shall be the act of the Board of Directors, unless the
act of a greater number is required by law, the articles of incorporation or 
these by-laws. In the absence of a quorum, a majority of those present may 
adjourn the meeting from time to time until a quorum is obtained, and no notice 
thereof need be given other than by announcement at the meeting which shall be 
adjourned. Upon the reconvening of any such adjourned meeting, if a quorum shall
be present, any business may be transacted which might have been transacted at 
the meeting originally convened.

          SECTION 7. Informal Action. Unless otherwise restricted by the 
                     ---------------
articles of incorporation or these by-laws, any action required or permitted to 
be taken at any meeting of the Board of Directors or of the Executive Committee 
may be taken without a meeting, if a written consent to such action is executed

case may be, and such written consent is filed with the minutes of proceedings 
of the Board of Directors or the Executive Committee.

          SECTION 8. Compensation. Directors shall not receive any stated salary
                     ------------
for their services as directors or as members of committees, but by resolution 
of the Board of Directors a fixed fee and expenses of attendance may be allowed 
for attendance at each meeting. Nothing herein contained shall be construed to 
preclude any director from serving the corporation in any other capacity and 
receiving compensation therefor.

          SECTION 9. Indemnification. (a) To the extent permitted by law, the 
                     ---------------
Board of Directors of the corporation may by resolution 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 (whether or not by or in the right

                                       5

 
of the corporation) by reason of the fact that such person is or was a director,
officer, employee or agent of the corporation, or is or was serving at the 
request of the corporation as a director, officer, employee or agent of another 
corporation, partnership, joint venture, trust or other enterprise, against 
expenses (including attorneys' fees), judgments, fines and amounts paid in 
settlement actually and reasonably incurred by him in connection with such 
action, suit or proceeding if he acted in good faith and in a manner he 
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 not 
reasonable cause to believe his 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 
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 conduct was unlawful.

          SECTION 9. (b) Any indemnification under Subsection (a) hereof (unless
          --------------
ordered by a court) shall be made by the Board of Directors only upon a 
determination in the specific case that indemnification of the director, 
officer, employee or agent is proper in the circumstances because he has met the
applicable standard of conduct set forth in said Subsection (a). Such 
determination shall be made (1) by the Board of Directors by a majority vote of 
a quorum consisting of directors who were not parties to such action, suit or 
proceeding, or (2) if such a quorum is not obtainable, or, even if obtainable
and a quorum of disinterested directors so directs, by independent legal counsel
(compensated by the corporation) in a written opinion, or (3) by the
stockholders

          SECTION 9. (c) The indemnification provided by this Section shall not
          --------------
be deemed exclusive of any other rights to which those indemnified may be 
entitled under any agreement, vote of stockholders, disinterested directors,
or otherwise, both as to the action in his official capacity and as to action in
another capacity while holding such office, and shall continue as to a person 
who has ceased to be a director, officer, employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such a person.

Dommittee or officer may resign at any time. Such resignation shall be made in
writing, and shall take effect at the time specified therein, and if no time be
specified, at the time of its actual receipt by the President or Secretary. The
acceptance of a resignation shall not be necessary to make it effective.

          SECTION 11. Vacancies. Vacancies occurring in the Board of Directors, 
                      --------- 
through death, resignation or otherwise, and newly created directorships 
resulting from an increase in the number of directors, may be filled by an 
election at an annual meeting or at a special meeting of shareholders called for
that purpose. The directors so chosen shall hold office until their successors 
are duly elected and shall qualify.

                      --------------------------

                     -----------------------------------------------------  
the purpose of determining the right of shareholders to vote or receive 
dividends, the Directors may provide that the stock transfer books shall be 
closed for a stated period not to exceed forty (40) days. In such event, the 
books shall be closed for the purpose of determining shareholders entitled to 
notice of or to vote at a meeting of shareholders for at least ten (10) days or 
in the case of a merger or consolidation at least 20 days, immediately prior to 
a meeting of the shareholders. In lieu of closing the stock transfer books, the 
Board of Directors may fix in advance a date as the record date for any such 
determination of shareholders, such date to be not more than 40 days, and, for a
meeting of shareholders, not less than 10 days or in case of a merger or 
consolidation, not less than 20 days, immediately preceding such meeting or 
payment of such dividend. If the Directors shall not so provide for a closing of
the transfer books or the fixing of a record date, then the date on which notice
of the meeting of the shareholders was given or the date on which the resolution
of the Board of Directors declaring a dividend was adopted, as the case may be, 
shall be the record date for determining

                                      11




 
the rights of shareholders. When a determination of shareholders entitled to
vote at a meeting of shareholders has been made as provided in this section,
such determination shall apply to any adjournment thereof.
