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 the power to adjourn the
meeting from time to time, without notice other than announcement at the

shall be signed by the holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a


                                       3


<PAGE>   4
meeting at which all shares entitled to vote thereon were present and voted.
Prompt notice of the taking of the corporate action without a meeting by less
than unanimous written consent shall be given as required by applicable law.

                                   ARTICLE III

                                    DIRECTORS

               SECTION 1. NUMBER AND TERM. The number of directors shall be five
(5). The directors shall be elected at the annual meeting of the stockholders
and each director shall be elected to serve until his successor shall be elected
and shall qualify. The directors need not be stockholders.

               SECTION 2. RESIGNATIONS. Any director, member of a committee or
other 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 receipt by the President or Secretary. The
acceptance of a resignation shall not be necessary to make it effective.

               SECTION 3. VACANCIES. If the office of any director, member of a
committee or other officer becomes vacant, the remaining directors in office,
though less than a quorum, by a majority vote, may appoint any qualified person
to fill such vacancy, who shall hold office for the unexpired term and until his
successor shall be duly chosen.

               SECTION 4. REMOVAL. Except as hereinafter provided, any director
or directors may be removed either for or without cause at any time by the
affirmative vote of the holders of a majority of all the shares of stock
outstanding and entitled to vote, at a special meeting of the stockholders
called for the purpose and the vacancies thus created may be filled,


                                       4


<PAGE>   5
at the meeting held for the purpose of removal, by the affirmative vote of a
majority in interest of the stockholders entitled to vote.

               Unless the Certificate of Incorporation otherwise provides,
stockholders may effect removal of a director who is a member of a classified
Board of Directors only for cause. If the Certificate of Incorporation provides
for cumulative voting and if less than the entire board is to be removed, no
director may be removed without cause if the votes cast against his removal
would be sufficient to elect him if then cumulatively voted at an election of
the entire board of directors, or if there be classes of directors, at an
election of the class of directors of which he is a part.

               If the holders of any class of series are entitled to elect one
or more directors by the provisions of the Certificate of Incorporation, these
provisions shall apply, in respect of the removal without cause of a director or
directors so elected, to the vote of the holders of the outstanding shares of
that class or series and not to the vote of the outstanding shares as a whole.

               SECTION 5. INCREASE OF NUMBER. The number of directors may be
increased by amendment of these By-laws by the affirmative vote of a majority of
the directors, or by the affirmative vote of a majority interest of the
stockholders, at the annual meeting or at a special meeting called for that
purpose, and by like vote the additional directors may be chosen at such meeting
to hold office until the next annual election and until their successors are
elected and qualify.

               SECTION 6. POWERS. The Board of Directors shall exercise all of
the powers of the corporation except such as are by law, or by the Certificate
of Incorporation or by these By-laws conferred upon or reserved to the
stockholders.


                                       5


<PAGE>   6
               SECTION 7. COMMITTEES. The Board of Directors may designate one
or more committees, each committee to consist of one or more directors of the
corporation. The Board of Directors may designate one or more directors as
alternate members of any committee, who may replace any absent or disqualified
member at any meeting of the committee. In the absence or disqualification of
any member of such committee or committees, the member or members thereof
present at any meeting and not disqualified from voting, whether or not he or
they constitute a quorum, may unanimously appoint another member of the Board of
Directors to act at the meeting in the place of any such absent or disqualified
member.

               Any such committee, to the extent provided in the resolution of
the Board of Directors, or in these By-laws, but subject to applicable law,
shall have and may exercise all the powers and authority of the Board of
Directors in the management of the business and affairs of the corporation, and
may authorize the seal of the corporation to be affixed to all papers which may
require it; but no such committee shall have the power or authority in reference
to amending the Certificate of Incorporation, adopting an agreement of merger or
consolidation, recommending to the stockholders the sale, lease or exchange of
all or substantially all of the corporation's property and assets, recommending
to the stockholders a dissolution of the corporation or a revocation of a
dissolution, or amending the By-laws of the corporation; and, unless the
resolution, these By-laws, or the Certificate of Incorporation expressly so
provide, no such committee shall have the power or authority to declare a
dividend or to authorize the issuance of stock.

               SECTION 8. MEETINGS. The newly elected directors may hold their
first meeting for the purpose of organization and the transaction of business,
if a quorum be present,


                                       6


<PAGE>   7
immediately after the annual meeting of the stockholders; or the time and place
of such meeting may be fixed by consent in writing of all the directors.

               Regular meetings of the directors may be held without notice at
such places and times as shall be determined from time to time by resolution of
the directors.

               Special meetings of the Board of Directors may be called by the
President or by the Secretary on the written request of any two directors on at
least two day's notice to each director and shall be held at such place or
places as may be determined by the directors, or shall be stated in the call of
the meeting.

               Unless otherwise restricted by the Certificate of Incorporation
or by these By-laws, members of the Board of Directors, or any committee
designated by the Board of Directors, may participate in a meeting of the Board
of Directors, or any committee, by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and such participation in a meeting shall
constitute presence in person at the meeting.

               SECTION 9. QUORUM. A majority of the directors shall constitute a
quorum for the transaction of business. If at any meeting of the Board of
Directors there shall be less than a quorum present, a majority of those present
may adjourn the meeting from time to time until a quorum is obtained, and no
further notice thereof need be given other than by announcement at the meeting
which shall be so adjourned.

               SECTION 10. 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


                                       7


<PAGE>   8
corporation in any other capacity as an officer, agent or otherwise, and
receiving compensation therefor.

               SECTION 11. ACTION WITHOUT MEETING. Any action required or
permitted to be taken at any meeting of the Board of Directors, or of any
committee thereof, may be taken without a meeting, if consent thereto is signed
by all members of the Board of Directors, or of such committee as the case may
be, in accordance with applicable law, and such written consent is filed with
the minutes of proceedings of the Board of Directors or committee.

                                   ARTICLE IV
