                                  STOCKHOLDERS
                                  ------------

         Section 1. Annual Meeting. The annual meeting of stockholders of the
Corporation shall be held each year at the principal office of the Corporation
in the State of Maryland, or at such other place, during the month of April, at
such date, hour and place within or without the State as may be fixed by the
Board of Directors for the purpose of election of Directors and for the
transaction of such other business as may properly come before the meeting.

         Section 2. Special Meeting. A special meeting of stockholders may be
called by the Board of Directors or by the President to be held at the principal
office of the Corporation in the State of Maryland or at such other place as may
be determined by the Board of Directors when such meeting is called. 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 50% of all the
votes entitled to be cast at such meeting; provided, however, unless requested
by stockholders entitled to cast a majority of all votes entitled to be cast at
such meeting, a special meeting need not be called for the purpose of
considering any matter which is substantially the same as a matter voted on at
any special meeting of the stockholders held during the preceding 12 months.
Such request shall state in general terms the purpose of such meeting and the
matters proposed to be acted on at such meeting. The Secretary shall inform such
stockholders of the reasonably estimated cost of preparing and mailing notice of
the meeting and, upon payment to the Corporation of such costs, the Secretary
shall give notice to each stockholder entitled to notice of the meeting. Notice
of such special meeting shall be given in the same manner as is provided in the
case of annual meetings.

         Section 3. Notice. Not less than 10 nor more than 90 days before each
meeting of stockholders, the Secretary shall give to each stockholder entitled
to vote at such meeting and to each stockholder not entitled to vote who is
entitled to notice of the meeting, 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 for which the meeting is called, either
by mail or by presenting it to such stockholder 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 thereon prepaid.

         Section 4. Scope of Notice. No business shall be transacted at a
special meeting of stockholders except that 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 5. Quorum. At any meeting of stockholders, the presence in
person or by proxy of stockholders entitled to cast a majority of all the votes
entitled to be cast at such meeting 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, such quorum shall not be
present at any meeting of the stockholders, the stockholders entitled to vote at
such meeting, present in person or by proxy, shall have the power to adjourn the
meeting from time to time to a date not more than 120 days after the original
record date without notice other than announcement at the meeting until such
quorum shall be present. At such adjourned meeting at which a quorum shall be
present, any business may be transacted which might have been transacted at the
meeting as originally notified.

         Section 6. 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
approve 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 of stock, regardless
of class, shall be entitled to one vote on each matter submitted to a vote at a
meeting of stockholders.

         Section 7. Proxies. A stockholder may vote the shares of stock 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 8. Voting of Shares by Certain Holders. Shares registered in
the name of another corporation, if entitled to be voted, may be voted by the
President, a Vice-President or a 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 bylaw
or resolution, in which case such person may vote such shares. Any fiduciary may
vote shares registered in his name as such fiduciary, either in person or by
proxy.

                                      -2-



         Shares of its own stock directly or indirectly owned by this
Corporation shall not be voted at any meeting and shall not be counted in
determining the total number of outstanding shares entitled to be voted at any
given time, unless they are held by it in a fiduciary capacity, in which case
they may be voted and shall be counted in determining the total number of
outstanding shares at any given time.

         The Board of Directors may adopt by resolution a procedure by which a
stockholder may certify in writing to the Corporation that any shares of stock
registered in the name of the stockholder are held for the account of a
specified person other than the stockholder. The resolution shall set forth the
class of stockholders who may certify, the purpose for which the certification
may be made, the form of certification and the information to be contained in
it; if the certification is with respect to a record date or closing of the
stock transfer books, the time after the record date or closing of the stock
transfer books within which the certification must be received by the
Corporation; and any other provisions with respect to the procedure which the
Board of Directors considers necessary or desirable. On receipt of such
certification, the person specified in the certification shall be regarded as,
for the purposes set forth in the certification, the stockholder of record of
the specified stock in place of the stockholder who makes the certification.

         Section 9. Inspectors. At any meetings 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 perform such other acts as are proper to conduct the election and
voting with impartiality and fairness to all the stockholders.

         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 10. 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 each
stockholder entitled to vote on the matter and any other stockholder entitled to
notice of a meeting of stockholders (but not to vote thereat) has waived in
writing any right to dissent from such action, and such consent and waiver are
filed with the minutes of proceedings of the stockholders.

                                      -3-



         Section 11. Voting by Ballot. Voting on 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.

         Section 12.  Nominations and Stockholder Business.

         (a) Annual Meetings of Stockholders. (1) Nominations of persons for
election to the Board of Directors and the proposal of business to be considered
by the stockholders may be made at an annual meeting of stockholders (i)
pursuant to the Corporation's notice of meeting, (ii) by or at the direction of
the Board of Directors or (iii) by any stockholder of the Corporation who was a
stockholder of record at the time of giving of notice provided for in this
Section 12(a), who is entitled to vote at the meeting and who complied with the
notice procedures set forth in this Section 12(a).

                           (2) For nominations or other business to be properly
brought before an annual meeting by a stockholder pursuant to clause (iii) of
paragraph (a)(1) of this Section 12, the stockholder must have given timely
notice thereof in writing to the Secretary of the Corporation. To be timely, a
stockholder's notice shall be delivered to the Secretary at the principal
executive offices of the Corporation not less than 60 days nor more than 90 days
prior to the first anniversary of the preceding year's annual meeting; provided,
however, that in the event that the date of the annual meeting is advanced by
more than 30 days or delayed by more than 60 days from such anniversary date,
notice by the stockholder to be timely must be so delivered not earlier than the
90th day prior to such annual meeting and not later than the close of business
on the later of the 60th day prior to such annual meeting or the tenth day
following the day on which public announcement of the date of such meeting is
first made. Such stockholder's notice shall set forth (i) as to each person whom
the stockholder proposes to nominate for election or reelection as a director
all information relating to such person that is required to be disclosed in
solicitations of proxies for election of directors, or is otherwise required, in
each case pursuant to Regulation 14A under the Securities Exchange Act of 1934,
as amended (the "Exchange Act") (including such person's written consent to
being named in the proxy statement as a nominee and to serving as a director if
elected); (ii) as to any other business that the stockholder proposes to bring
before the meeting, a brief description of the business desired to be brought
before the meeting, the reasons for conducting such business at the meeting and
any material interest in such business of such stockholder and of the beneficial
owner, if any, on whose behalf the proposal is made; and (iii) as to the
stockholder giving the notice and the beneficial owner, if any, on whose behalf
the nomination or proposal is made, (x) the name and address of such
stockholder, as they appear on the Corporation's books, and of such beneficial
owner and (y) the number of shares of each class of stock of the

                                      -4-



Corporation which are owned beneficially and of record by such stockholder and
such beneficial owner.

                  (3) Notwithstanding anything in the second sentence of
paragraph (a)(2) of this Section 12 to the contrary, in the event that the
number of directors to be elected to the Board of Directors is increased and
there is no public announcement naming all of the nominees for director or
specifying the size of the increased Board of Directors made by the Corporation
at least 70 days prior to the first anniversary of the preceding year's annual
meeting, a stockholder's notice required by this Section 12(a) shall also be
considered timely, but only with respect to nominees for any new positions
created by such increase, if it shall be delivered to the Secretary at the
principal executive offices of the Corporation not later than the close of
business on the tenth day following the day on which such public announcement is
first made by the Corporation.

         (b) Special Meetings of Stockholders. Only such business as shall have
been brought before the meeting pursuant to the Corporation's notice of meeting
shall be conducted at a special meeting of stockholders. Nominations of persons
for election to the Board of Directors may be made at a special meeting of
stockholders at which directors are to be elected: (i) pursuant to the
Corporation's notice of meeting; (ii) by or at the direction of the Board of
Directors; or (iii) provided that the Board of Directors has determined that
directors shall be elected at such special meeting, by any stockholder of the
Corporation who is a stockholder of record at the time of giving of notice
provided for in this Section 12(b), who is entitled to vote at the meeting and
who complied with the notice procedures set forth in this Section 12(b). In the
event the Corporation calls a special meeting of stockholders for the purpose of
electing one or more directors to the Board of Directors, any such stockholder
may nominate a person or persons (as the case may be) for election to such
position as specified in the Corporation's notice of meeting, if the
stockholder's notice containing the information required by paragraph (a)(2) of
this Section 12 shall be delivered to the Secretary at the principal executive
offices of the Corporation not earlier than the 90th day prior to such special
meeting and not later than the close of business on the later of the 60th day
prior to such special meeting or the tenth day following the day on which public
announcement is first made of the date of the special meeting and of the
nominees proposed by the Board of Directors to be elected at such meeting.

         (c) General. (1) Only such persons who are nominated in accordance with
the procedures set forth in this Section 12 shall be eligible to serve as
directors and only such business shall be conducted at a meeting of stockholders
as shall have been brought before the meeting in accordance with the procedures
set forth in this Section 12. The presiding officer of the meeting shall have
the power and duty to determine whether a nomination or any business proposed to
be brought before the meeting was

                                      -5-



made in accordance with the procedures set forth in this Section 12 and, if any
proposed nomination or business is not in compliance with this Section 12, to
declare that such defective nomination or proposal be disregarded.

                  (2) For purposes of this Section 12, "public announcement"
shall mean disclosure in a press release reported by the Dow Jones News Service,
Associated Press or comparable news service or in a document publicly filed by
the Corporation with the Securities and Exchange Commission pursuant to Section
13, 14 or 15(d) of the Exchange Act.

                  (3) Notwithstanding the foregoing provisions of this Section
12, a stockholder shall also comply with all applicable requirements of state
law and of the Exchange Act and the rules and regulations thereunder with
respect to the matters set forth in this Section 12. Nothing in this Section 12
shall be deemed to affect any rights of stockholders to request inclusion of
proposals in the Corporation's proxy statement pursuant to Rule 14a-8 under the
Exchange Act.

                                   ARTICLE II

                               BOARD OF DIRECTORS
                               ------------------

         Section 1. Powers. The business and affairs of the Corporation shall be
managed under the direction of its Board of Directors. All powers of the
Corporation may be exercised by or under the authority of the Board of Directors
except as conferred on or reserved to the stockholders by law, by the Charter or
by these Bylaws. A Director need not be a stockholder. The Board of Directors
shall keep minutes of its meetings and full and fair accounts of its
transactions.

         Section 2. Number and Term of Office. The Board of Directors shall
consist of such number of Directors as the Board of Directors shall designate
from time to time. The members of the Board of Directors shall be elected to
serve for terms of three (3) years. Unless otherwise provided in the applicable
resolution electing the Director, a Director shall hold office until the annual
meeting for the year in which his term expires and until his successor is
elected and qualifies, or until his death, resignation or removal in the manner
provided in SECTION 9 of this ARTICLE II.

         Section 3. Election of Directors. The Board of Directors shall be
divided into three classes. Each such class shall consist, as nearly as
possible, of one-third of the total number of Directors, and any remaining
Directors shall be included within each such class or classes as the Board of
Directors shall designate. At each annual meeting of stockholders, successors to
the class of Directors whose term expires at that annual

                                      -6-



meeting shall be elected for a term of three years. In the event of the failure
to elect Directors at an annual meeting of the stockholders, then Directors may
be elected at any regular or special meeting of stockholders entitled to vote
for the election of Directors, provided that notice of such meeting shall
contain mention of such purpose. If the number of Directors is changed, any
increase or decrease shall be apportioned among the classes so as to maintain
the number of Directors in each class as nearly equal as possible. Except as
otherwise provided in the Charter, at each meeting of the stockholders for the
election of directors, provided a quorum is present, the Directors shall be
chosen and elected by a plurality of the votes validly cast at such election.

         Section 4. Vacancies. If the office of a Director becomes vacant for
any reason other than removal or increase in the size of the Board, such vacancy
may be filled by the Board by a vote of a majority of Directors then in office,
although such majority is less than a quorum.

         Section 5. Annual Meetings. An annual meeting of the Board of Directors
shall immediately follow the annual meeting of stockholders each year. No notice
of the annual meeting need be given to the Directors.

         Section 6. Special Meetings. Special Meetings of the Board of Directors
may be called at any time by the President, Chairman of the Board or by any two
Directors, to be held at the principal office of the Corporation in the State of
Maryland, or at such other place or places as the Directors may from time to
time designate. Notice of special meetings of the Board of Directors shall be
given to each Director at least twenty four (24) hours prior to the meeting by
service to the Director by telegram, letter or by personal notice, including
telephone notice.

         Section 7. Quorum. A quorum for the transaction of business at every
meeting of the Board of Directors shall consist of a majority of the Board of
Directors, and the vote of a majority of those present at a meeting at which a
quorum is present shall be required to pass any measure or resolution unless a
greater number is required by statute or by the Charter or by these Bylaws. If
less than a quorum of Directors is present at said meeting, a majority of the
Directors present may 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 8. Telephone Meetings. Members of the Board of Directors may
participate in a meeting by means of a conference telephone or similar
communications equipment if all persons participating in the meeting can hear
each other at the same time.

                                      -7-



Participation in a meeting by these means shall constitute presence in person at
the meeting.

         Section 9. Informal Action by Directors. Any action required or
permitted to be taken at any meeting of the Board of Directors may be taken
without a meeting, if an unanimous written consent which sets forth the action
is signed by each Director and such consent is filed with the minutes of
proceedings of the Board of Directors.

         Section 10. Compensation. Directors shall not receive any stated salary
for their services as Directors but, by resolution of the Board of Directors, a
fixed sum and expenses of attendance, if any, may be allowed to Directors for
attendance at each annual, regular or special meeting of the Board of Directors
or of any committee thereof; but nothing herein contained shall be construed to
preclude any Director from serving the Corporation in any other capacity and
receiving compensation therefor.

         Section 11. Removal of Directors. Any Director of the Corporation may
be removed with cause by the affirmative vote of the holders of seventy-five
percent (75%) of all the votes entitled to be cast for the election of
Directors, but no Director may be removed by the stockholders without cause.
Except as otherwise provided by contract, any vacancy in the Board of Directors
caused by any such removal may be filled at such meeting or any adjournment of
such meeting by the holders of shares of stock of all classes representing a
majority of the aggregate number of votes of the shares of stock of all classes
then issued, outstanding and entitled to vote for the election of Directors. If
such stockholders do not fill such vacancy at such meeting, such vacancy may be
filled in any other manner permitted by law.

                                   ARTICLE III

                                   COMMITTEES

composed of two or more Directors, to serve at the pleasure of the Board of
Directors.

         Section 2. Powers. The Board of Directors may delegate to committees
appointed under SECTION 1 of this Article any of the powers of the Board of
Directors except as prohibited by law.

         Section 3. Meetings. In the absence of any member of any such
committee, the members thereof present at any meeting, whether or not they
constitute a quorum, may appoint a Director to act in the place of such absent
member.

                                      -8-




         Section 4. Telephone Meetings. Members of a committee of the Board of
Directors may participate in a meeting by means of a conference telephone or
similar communications equipment if all persons participating in the meeting can
hear each other at the same time. Participation in a meeting by these means
shall constitute presence in person at the meeting.

         Section 5. Informal Action by Committees. Any action required or
permitted to be taken at any meeting of a committee of the Board of Directors
may be taken without a meeting, if an unanimous consent which sets forth the
action is signed by each member of the committee and such consent is filed with
the minutes of the proceedings of such committee.

         Section 6. Minutes of Meetings. The minutes of any meeting of a
committee shall be distributed to each member of the Board of Directors.

                                   ARTICLE IV

                                    OFFICERS
                                    --------

Executive Officer, Chief Operating Officer, Chief Financial Officer, Chairman of
the Board, a Vice Chairman of the Board, additional Vice Presidents, one or more
Assistant Treasurers, one or more Assistant Secretaries and such other officers
as the Board may determine from time to time. The officers of the Corporation
shall be elected annually by the Board of Directors at the first meeting of the
Board of Directors held after each annual meeting of stockholders. If the
election of officers shall not be held at such meeting, such election shall be
held as soon thereafter as may be convenient. Each officer shall hold office
until his successor is duly elected and qualifies or until his death,
resignation or removal in the manner hereinafter provided. Any two or more
offices except President and Vice President may be held by the same person. In
its discretion, the Board of Directors may leave vacant any office except that
of President, Treasurer and Secretary. Election or appointment of an officer or
agent shall not in itself create contract rights between the Corporation and
such officer or agent.

         Section 2. Removal. Any officer or agent of the Corporation may be
removed by the Board of Directors if in its judgment the best interests of the
Corporation would be served thereby, but such removal shall be without prejudice
to the contract rights, if any, of the person so removed.

                                      -9-

Board of Directors and of the stockholders at which he shall be present. In the
absence of a designation of a Chief Executive Officer by the Board of Directors,

more than one Vice President, the Vice Presidents in the order designated at the
time of their election or, in the absence of any designation, then in the order
of their election) shall perform the duties of the President and when so acting
shall have all the powers of and be subject to all the restrictions upon the
President; and shall perform such other duties as from time to time may be
assigned to him by the President or by the Board of Directors. The Board of
Directors may designate one or more Vice Presidents as executive, senior or
Assistant Vice President or as Vice President for particular areas of

                                      -10-

Board of Directors, taking proper vouchers for such disbursements, and shall
render to the President and Board of Directors, at the regular meetings of the
Board or whenever they may require it, an account of all his transactions as
Treasurer and of the financial condition of the Corporation.

         If required by the Board of Directors, he shall give the Corporation a

                                      -11-



give bonds for the faithful performance of their duties in such sums and with
such sureties as shall be satisfactory to the Board of Directors.

         Section 13. Compensation. The compensation of the officers shall be
fixed from time to time by the Board of Directors and no officer shall be
prevented from receiving such compensation by reason of the fact that he is also
a Director of the Corporation.

                                    ARTICLE V

                      CONTRACTS, LOANS, CHECKS AND DEPOSITS
                      -------------------------------------

         Section 1. Contracts. The Board of Directors may authorize any officer
or agent to enter into any contract or to execute and deliver any instrument in
the name of and on behalf of the Corporation and such authority may be general
or confined to specific instances.

         Section 2. Checks and Drafts. All checks, drafts or other orders for
the payment of money, notes or other evidences of indebtedness issued in the
name of the Corporation shall be signed by such officer or officers, agent or
agents of the Corporation and in such manner as shall from time to time be
determined by the Board of Directors.

         Section 3. Deposits. All funds of the Corporation not otherwise
employed shall be deposited from time to time to the credit of the Corporation
in such banks, trust companies or other depositories as the Board of Directors

                                   ARTICLE VI

                                 SHARES OF STOCK
                                 ---------------

         Section 1. Certificates of Stock. Each stockholder shall be entitled to
a certificate or certificates which shall represent and certify the number of
shares of each class of stock held by him in the Corporation. Each certificate
shall be signed by the President or 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; and if the
Corporation shall, from time to time, issue several classes of stock, each class
may have its own number series. A certificate is valid and may be issued whether
or not an officer who signed it is still an officer when it is issued. Each
certificate representing stock which is restricted 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

                                      -12-



or redemption provision, or a summary thereof, plainly stated on the
certificate. In lieu of such statement of 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 and without charge, a full statement of
such information.

         Section 2. Transfers of Stock. Upon surrender to the Corporation or the
transfer agent of the Corporation of a certificate of stock duly endorsed or
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 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 place of any certificate previously issued by the
Corporation alleged to have been lost, stolen or destroyed upon the making of an
affidavit of that fact by the person claiming the certificate of stock to be
lost, stolen 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 lost, stolen 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 as a result of the
issuance of a new certificate.

         Section 4. Closing of Transfer Books or Fixing of Record Date. The
Board of Directors may set, in advance, a 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 other rights, or in order to make a determination of
stockholders for any other proper purpose. Such date, in any case, shall not be
prior to the close of business on the day the record date is fixed and shall be
not more than 90 days, and in the case of a meeting of stockholders not less
than 10 days, before 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 longer
than 20 days. If the stock transfer books are closed for the purpose of
determining stockholders entitled to notice of

                                      -13-



or to vote at a meeting of stockholders, such books shall be closed for at least
10 days before the date of 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 other rights shall be
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 5. Stock Ledger. The Corporation shall maintain at its
principal office or at the office of its counsel, accountants or transfer agent,
an original or duplicate stock ledger containing the name and address of each
stockholder and the number of shares of stock of each class held by such
stockholder.

                                   ARTICLE VII

                                    DIVIDENDS
                                    ---------

         Section 1. Declaration. Dividends upon the shares of stock of the
Corporation may be declared by the Board of Directors, subject to the provisions
of law and the Charter of the Corporation. Dividends may be paid in cash,
property or shares of the Corporation, subject to the provisions of law and the
Charter of the Corporation.

         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 for contingencies, for equalizing
dividends, for repairing or maintaining any property of the Corporation or for
such other purpose or purposes 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.

                                      SEAL
                                      ----

         Section 1. Seal. The corporate seal, if the Corporation shall decide to
have a seal, shall have inscribed thereon the name of the Corporation, the year
of its organization and the word "Maryland". The Board of Directors may
authorize one or more duplicate seals and provide for the custody thereof.

         Section 2. Affixing Seal. Whenever the Corporation is required to place
its corporate seal to a document, it shall be sufficient to meet the
requirements of any law, rule or regulation relating to a corporate seal to
place the word "(SEAL)" adjacent to the signature of the person authorized to
execute the document on behalf of the Corporation.

                                   ARTICLE IX

                                   FISCAL YEAR
                                   -----------

         The fiscal year of the Corporation shall end on the 31st day of
December of each year unless otherwise provided by the Board of Directors.

                                    ARTICLE X

                                 INDEMNIFICATION
                                 ---------------

         Section 1. General. The Corporation shall indemnify: (i) any individual
who is a present or former Director or officer of the Corporation; or (ii) any
individual who serves or has served in another corporation, partnership, joint
venture, trust, employee benefit plan or any other enterprise as a director or
officer, or as a partner or trustee of such partnership or employee benefit
plan, at the request of the Corporation and who by reason of service in that
capacity was, is or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative, to the full extent permitted under the Maryland General
Corporation Law. The Corporation may, with the approval of its Board of
Directors, provide such indemnification for a person who formerly served a
predecessor of the Corporation in any of the capacities described in (i) or (ii)
above and for any employee or agent of the Corporation or a predecessor of the
Corporation.

         Section 2. Advancement of Expenses. Reasonable expenses incurred by a
Director or officer who is or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or

                                      -15-



investigative, shall be paid or reimbursed by the Corporation in advance of the
final disposition of the proceeding upon receipt by the Corporation of: (i) a
written affirmation by the party seeking indemnification that he has a good
faith belief that the standard of conduct necessary for indemnification by the
Corporation as authorized herein has been met; and (ii) a written undertaking by
or on behalf of the party seeking indemnification to repay the amount if it
shall ultimately be determined that the standard of conduct has not been met.

                                   ARTICLE XI

                                WAIVER OF NOTICE
                                ----------------

         Whenever any notice is required to be given pursuant to the Charter or
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
ground that the meeting is not lawfully called or convened.

                                   ARTICLE XII

                               AMENDMENT OF BYLAWS

entitled to be cast thereon, except that SECTIONS 2, 3 AND 9 of ARTICLE II and
this ARTICLE XII may be altered, amended or repealed, and any bylaw or provision

(considered for this purpose as a single class) or by the Board of Directors, as
applicable.
