                            MEETINGS OF STOCKHOLDERS

         1.1 PLACE. All meetings of the holders of the issued and outstanding
capital stock of the Corporation (the "Stockholders") shall be held at the
principal executive office of the Corporation or such other place within the
United States as shall be stated in the notice of the meeting.

         1.2 ORGANIZATION MEETING; ANNUAL MEETING. An annual meeting of the
Stockholders for the election of Directors and the transaction of such other
business as properly may be brought before the meeting shall be held on the last
Wednesday in January of each year or at such other date and time as may be fixed
by the Board of Directors. If the date fixed for the annual meeting shall be a
legal holiday, such meeting shall be held on the next succeeding business day.
If no annual meeting is held on the date designated, a special meeting in lieu
thereof may be held, and such special meeting shall have, for purposes of these
Bylaws or otherwise, all the force and effect of an annual meeting. Any and all
references hereinafter in these Bylaws to an annual meeting or to annual
meetings shall be deemed to refer also to any special meeting(s) in lieu
thereof.

         1.3 MATTERS TO BE CONSIDERED AT ANNUAL MEETING. Except as provided by
Title 2, Subtitle 5, of the Maryland General Corporation Law, as amended from
time to time, any business may be conducted and any proposals may be acted upon
at an annual meeting of Stockholders. The purpose of the annual meeting of
Stockholders need not be specified in the notice of the annual meeting of
Stockholders.

         1.4 SPECIAL MEETINGS. The Chairman of the Board, the President or a
majority of the Board of Directors may call special meetings of the
Stockholders. Special meetings of Stockholders shall also be called by the
Secretary upon the written request of the holders of shares entitled to cast 25%
or more of the votes entitled to be cast at such meeting. Such request shall
state the purpose or purposes of such meeting and the matters proposed to be
acted on thereat.

         1.5 NOTICE. Not less than ton (10) nor more than ninety (90) days
before the date of every meeting of Stockholders, written or printed notice of
such meeting shall be given, in accordance with Article VIII, to each
Stockholder entitled to vote or entitled to notice by statute, stating the time
and place of the meeting and, in the case of a special meeting or as otherwise
may be required by statute, the purpose or purposes for which the meeting to
called.

         1.6 SCOPE OF NOTICE. No business shall be transacted at a special
meeting of Stockholders except that specifically designated in the notice of the
meeting. Any business of the Corporation may be transacted at the annual meeting
without being specifically designated in the notice, except such business as is
required by statute to be stated in such notice.

         1.7 QUORUM. At any meeting of stockholders, the presence in person or
by proxy of Stockholders entitled to cast a majority of the votes shall
constitute a quorum; but this Section shall not affect any requirement under any
statute or the Articles of Incorporation of the Corporation, as amended 



from time-to-time (the "Charter"), for the vote necessary for the adoption of
any measure. If, however, a quorum is not present at any meeting of the
Stockholders, the Stockholders present in person or by proxy shall have the
power to adjourn the meeting from time to time without notice other than by
announcement at the meeting until a quorum is present, and the meeting so
adjourned may be reconvened without further notice. At any adjourned meeting at
which a quorum is present, any business may be transacted that might have been
transacted at the meeting as originally notified. The Stockholders present at a
meeting which has been duly called and convened and at which a quorum is present
at the time counted may continue to transact business until adjournment,
notwithstanding the withdrawal of enough Stockholders to leave less than a
quorum.

         1.8 VOTING. A majority of the votes cast at a meeting of Stockholders
duly called and at which a quorum is present shall be sufficient to take or
authorize action upon any matter which may properly come before the meeting,
unless more than a majority of the votes cast is specifically required by
statute, the Charter or the Bylaws. Unless otherwise provided by statute, the
Charter or these Bylaws, each outstanding share (a "Share") of capital stock of
the Corporation (the "Stock"), regardless of class, shall be entitled to one
vote upon each matter submitted to a vote at a meeting of Stockholders. Pursuant
to Section 3-702 of the Maryland General Corporation Law, any and all
acquisitions of Shares of Stock are hereby exempted from the provisions of Title
3, Subtitle 7 of the Maryland General Corporation Law, which relates to voting
rights of certain control shares. Shares of its own Stock directly or indirectly
owned by the Corporation shall not be voted in any meeting and shall not be
counted in determining the total number of outstanding Shares entitled to vote
at any given time, but Shares of its own voting Stock held by it in a fiduciary
capacity may be voted and shall be counted in determining the total number of
outstanding Shares at any given time.

         1.9 PROXIES. A Stockholder may vote the Shares owned of record by him
or her, either in person or by proxy executed in writing by the Stockholder or
by his or her duly authorized attorney in fact. Such proxy shall be filed with
the Secretary of the Corporation before or at the time of the meeting. No proxy
shall be valid after eleven (11) months from the date of its execution, unless
otherwise expressly provided in the proxy.

         1.10 CONDUCT OF MEETINGS. The Chairman of the Board or, in the absence
of the Chairman, the President, or, in the absence of the Chairman, President
and Vice Presidents, a presiding Officer elected at the meeting, shall preside
over meetings of Stockholders. The Secretary of the Corporation, or, in the
absence of the Secretary and Assistant Secretaries, the person appointed by the
presiding Officer of the meeting, shall act as secretary of such meeting.

         1.11 TABULATION OF VOTES. At any annual or special meeting of
Stockholders, the presiding Officer shall be authorized to appoint a teller for
such meeting (the "Teller"). The Teller may, but need not, be an Officer or
employee of the Corporation. The Teller shall be responsible for tabulating, or
causing to be tabulated Shares voted at the meeting and reviewing or causing to
be reviewed all proxies. In tabulating votes, the Teller shall be entitled to
rely in whole or in part on tabulations and analyses made by personnel of the
Corporation, its counsel, its transfer 



agent, its registrar or such other organizations that are customarily employed
to provide such services. The Teller shall be authorized to determine the
legality and sufficiency of all votes cast and proxies delivered under the
Corporation's Charter, Bylaws and applicable law. The presiding Officer may
review all determinations made by the Teller hereunder and, in doing so, the
presiding Officer shall be entitled to exercise his or her sole judgment and
discretion and he or she shall not be bound by any determinations made by the
Teller.

         1.12 INFORMAL ACTION BY STOCKHOLDERS. An action required or permitted
to be taken at a meeting of Stockholders may be taken without a meeting if a
consent in writing, setting forth such action, is signed by all the Stockholders
entitled to vote on the subject matter thereof and any other Stockholders
entitled to notice of a meeting of Stockholders (but not to vote thereat) have
waived in writing any rights which they may have to dissent from such action,
and such consents and waivers are filed with the minutes of proceedings of the
Stockholders. Such consents and waivers may be signed by different Stockholders
on separate counterparts, and facsimile signatures appearing thereon may be
accepted for all purposes in lieu of original signatures.

         1.13 VOTING BY BALLOT. Voting an any question or in any election may
be viva voce unless the presiding Officer shall order or any Stockholder shall
demand that voting be by ballot.
