         Section 1. PLACE. All meetings of stockholders shall be held at the
principal office of the corporation or at such other place within the United
States as shall be stated in the notice of the meeting.

         Section 2. ANNUAL MEETING. An annual meeting of the stockholders for
the election of directors and the transaction of any business within the powers
of the corporation shall be held within six (6) months of the close of the
corporation's fiscal year at such location and at such date and time as may be
fixed by the Board of Directors. If the day fixed for the annual meeting shall
be a legal holiday, such meeting shall be held at the same time on the next
succeeding business day.

         Section 3. SPECIAL MEETINGS. The President or 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 not less than thirty three percent (33%) of all 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. The
Secretary shall inform such stockholders of the reasonably estimated cost of
preparing and mailing such notice of the meeting, and upon payment to the
corporation of such costs, the Secretary shall give notice stating the purpose
or purposes of the meeting to all stockholders entitled to vote at such meeting.
No special meeting need be called upon the request of the holders of shares
entitled to cast less than a majority of all votes entitled to be cast at such
meeting, to consider any matter which is substantially the same as a matter
voted upon at any special meeting of the stockholders held during the preceding
twelve months.

         Section 4. NOTICE. Not less than ten nor more than ninety days before
the date of every meeting of stockholders, the Secretary shall give, to each
stockholder entitled to vote who is entitled to notice by statute, written or
printed notice 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 is called, either by mail or by presenting it to
him personally or by leaving it at his residence or usual place of business. If
mailed, such notice shall be deemed to be given when deposited in the United
States mail addressed to the stockholder at his post office address as it
appears on the records of the corporation, with postage prepaid.

         Section 5. SCOPE OF NOTICE. No business shall be transacted at a
special meeting of stockholders except that specifically designated in the
notice. 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.





         Section 6. 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 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
announcement at the meeting until a quorum is present. At any adjourned meeting
at which a quorum is present, any business may be transacted which 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.

         Section 7. 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 required by statute or
by the charter. Unless otherwise provided in the charter, each outstanding
share, regardless of class, shall be entitled to one vote upon each matter
submitted to a vote at a meeting of stockholders.

         Section 8. PROXIES. A stockholder may vote the shares owned of record
by him, either in person or by proxy executed in writing by the stockholder or
by his 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 months from the date of its execution, unless
otherwise provided in the proxy.

         Section 9. VOTING OF SHARES BY CERTAIN HOLDERS. Shares standing in the
name of another corporation, when entitled to be voted, may be voted by the
president or vice-president or by proxy appointed by the president or a
vice-president of such other corporation, unless some other person who has been
appointed to vote such shares pursuant to a bylaw or a resolution of the Board
of Directors of such other corporation presents a certified copy of such bylaws
or resolution, in which case such person may vote such shares. Any fiduciary may
vote shares standing in his name as such fiduciary, either in person or by
proxy.

         Shares of its own stock directly or indirectly owned by this
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 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.

         Section 10. INSPECTORS. At any meeting of stockholders, the chairman of
the meeting may, or upon the request of any stockholder shall, appoint one or
more persons as inspectors for such meeting. Such inspectors shall ascertain and
report the number of shares represented at the meeting based upon their
determination of the validity and effect of proxies, count all votes, report the
results and do such other acts as are proper to conduct the election and voting
with impartiality and fairness to all the stockholders.


                                       2




         Each report of an inspector shall be in writing and signed by him or by
a majority of them if there be more than one inspector acting at such meeting.
If there is more than one inspector, the report of a majority shall be the
report of the inspectors. The report of the inspector or inspectors on the
number of shares represented at the meeting and the results of the voting shall
be prima facie evidence thereof.

         Section 11. INFORMAL ACTION BY STOCKHOLDERS. Any 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.

Board of Directors need be specified in the notice, unless specifically required
by statute or these Bylaws.

adjourn the meeting from time to time without further notice.

         The directors present at a meeting which has been duly called and
convened may continue to transact business until adjournment, notwithstanding
the withdrawal of enough directors to leave less than a quorum.

         Section 7. VOTING. The action of the majority of the directors present
at a meeting at which a quorum is present shall be the act of the Board of
Directors, unless the concurrence of a greater proportion is required for such
action by applicable statute or these Bylaws.

         Section 8. VACANCIES. Any vacancy occurring in the Board of Directors
for any cause other than by reason of an increase in the number of directors may
be filled by a majority vote of the remaining directors, although such majority
is less than a quorum. Any vacancy occurring in the Board of Directors by reason
of an increase in the number of directors may be filled by a majority vote of
the entire Board of Directors. A director elected by the Board of Directors to
fill a vacancy shall hold office until the next annual meeting of stockholders
or until his or her successor is elected and qualifies.

stated salary for their services, but, by resolution of the Board of Directors,
a fixed sum and expenses of attendance, if any, may be allowed to directors for

shares of each class of stack owned by him or her in the corporation. Each
certificate shall be signed by the President or a Vice President and
countersigned by the Secretary or an Assistant Secretary or the treasurer or an
assistant treasurer and may be sealed with the corporate seal. The signatures
may be either manual or facsimile. Certificates shall be consecutively numbered.
If the corporation issues, from time to time, several classes of stock, each
class may have its own number or series. In case any officer who has signed any
certificate ceases to be an officer of the corporation before the certificate is
issued, the certificate may nevertheless be issued by the corporation with the
same effect as if the officer has not ceased to be such officer as of the date
of its issue. Each certificate representing stock which is restricted or limited
as to its transferability or voting powers, which is preferred or limited as to
its dividends or as to its share of the assets upon liquidation or which is
redeemable at the option of the corporation, shall have a statement of such
restriction, limitation, preference or redemption provisions, or a summary
thereof, plainly stated on the certificate. In lieu of such statement or
summary, the corporation may set forth upon the face or back of the certificate
a statement that the corporation will furnish to any stockholder, upon request

accompanied by proper evidence of succession, assignment or authority to
transfer, the corporation shall issue a new certificate to the person entitled
thereto, cancel the old certificate and record the transaction upon its books.

         The corporation shall be entitled to treat the holder of record of any
share or shares of stock as the holder in fact thereof and, accordingly, shall
not be bound to recognize any equitable


                                       7



or other claim to or interest in such share on the part of any other person,
whether or not it shall have express or other notice thereof, except as
otherwise provided by the laws of the State of Maryland.

         Section 3. LOST CERTIFICATE. The Board of Directors may direct a new
certificate to be issued in the place of any certificate theretofore issued by
the corporation alleged to have been stolen, lost or destroyed upon the making
of an affidavit of that fact by the person claiming the certificate of stock to
be stolen, lost or destroyed. When authorizing such issue of a new certificate,
the Board of Directors may, in its discretion and as a condition precedent to
the issuance thereof, require the owner of such stolen, lost or destroyed
certificate or his legal representative to advertise the same in such manner as
it shall require and/or to give bond, with sufficient surety, to the corporation
to indemnify it against any loss or claim which may arise by reason of the
issuance of a new certificate.

         Section 4. CLOSING OF TRANSFER BOOKS OR FIXING OF RECORD DATE. The
Board of Directors may fix, in advance, a date as the record date for the
purpose of determining stockholders entitled to notice of, or to vote at, any
meeting of stockholders, or stockholders entitled to receive payment of any
dividend or the allotment of any rights, or in order to make a determination of
stockholders for any other proper purpose. Such date, in any case, shall be not
more than ninety (90) days, and in case of a meeting of stockholders not less
than ten (10) days, prior to the date on which the meeting or particular action
requiring such determination of stockholders is to be held or taken.

         In lieu of fixing a record date, the Board of Directors may provide
that the stock transfer books shall be closed for a stated period but not to
exceed twenty (20) days. If the stock transfer books are closed for the purpose
of determining stockholders entitled to notice of or to vote at a meeting of
stockholders, such books shall be closed for at least ten (10) days immediately
preceding such meeting.

         If no record date is fixed and the stock transfer books are not closed
for the determination of stockholders, (a) the record date for the determination
of stockholders entitled to notice of, or to vote at, a meeting of stockholders
shall be at the close of business on the day on which the notice of meeting is
mailed or the 30th day before the meeting, whichever is the closer date to the
meeting; and (b) the record date for the determination of stockholders entitled
to receive payment of a dividend or an allotment of any rights shall be at the
close of business on the day on which the resolution of the Board of Directors,
declaring the dividend or allotment of rights, is adopted.

         When a determination of stockholders entitled to vote at any meeting of
stockholders has been made as provided in this section, such determination shall
apply to any adjournment thereof, except where the determination has been made
through the closing of the stock transfer books and the stated period of closing
has expired.

         Section 2. CONTINGENCIES. Before payment of any dividends, there may be
set aside out of any funds of the corporation available for dividends such sum
or sums as the Board of Directors may from time to time, in its absolute
discretion, think proper as a reserve fund to meet contingencies, for equalizing
dividends, for repairing or maintaining any property of the corporation or for
such other purpose as the Board of Directors shall determine to be in the best
interest of the corporation, and the Board of Directors may modify or abolish
any such reserve in the manner in which it was created.

requirements of law, rule or regulation relating to a corporate seal to place
the word "(seal)" adjacent to the signature of the authorized officer.

                                   ARTICLE XI
                                 INDEMNIFICATION

extent permitted by the general corporate laws of the State of Maryland, now or

                                       9




         In addition to any indemnification permitted by these Bylaws, the Board
of Directors shall, in its sole discretion, have the power to grant such
indemnification as it deems in the interest of the corporation to the full
extent permitted by law.

         The corporation shall have power to purchase and maintain insurance on
behalf of any person who is or was serving the corporation or any other entity
at the request of the corporation, in any capacity, against any liability,

such liability.

         This Article shall not limit the corporation's power to indemnify
against liabilities other than those arising from a person's serving the
corporation as an officer, director, employee or agent.

Bylaws of the corporation or pursuant to applicable law, a waiver thereof in
writing, signed by the person or persons entitled to such notice, whether before
or after the time stated therein, shall be deemed equivalent to the giving of
such notice. Neither the business to be transacted at nor the purpose of any
meeting need be set forth in the waiver of notice, unless specifically required
by statute. The attendance of any person at any meeting shall constitute a
waiver of notice of such meeting, except where such person attends a meeting for
the express purpose of objecting to the transaction of any business on the
