Board of Directors, and during such period no stock shall be transferred upon
said books.

                  SECTION 4. LOST CERTIFICATES. In case of the loss of any
certificate of shares of stock, upon affidavit by the registered holder or his
representative of such loss, and subject to any additional requirement of the
Board of Directors, the Secretary shall issue a duplicate certificate in its
place, upon the Corporation's being fully indemnified therefor.

                                                                               1

year, if not a legal holiday, and if a legal holiday, then on the day following,

business as may be brought before the meeting.

                  SECTION 2. SPECIAL MEETINGS. Special meetings of the
shareholders may be called by the President and Secretary, and shall be called

shall be mailed to each shareholder at his last known address, as the same
appears on the stock books of the Corporation, or otherwise, at least ten days
prior to any meeting. Any notice of a special meeting shall indicate briefly the
object or objects thereof. If all the shareholders waive notice of the meeting,
no notice of the same shall be required; and whenever all the shareholders shall
meet in person or by proxy, such meeting shall be valid for all purposes,
without call or notice, and at such meeting any corporate action shall not be
invalid for want of notice.

                  SECTION 4. QUORUM. At any meeting of the shareholders, the
holders of sixty percent of all the voting shares of the Capital Stock of the

attend, without further notice other than the announcement at such meeting; and

share of voting stock standing registered in his or her name on the stock books
of the Corporation, in person or by proxy duly appointed in writing and filed
with the Secretary of the meeting, on all questions and elections. No proxy
shall be voted after three years from its date unless said proxy provides for a

Corporation; but in the absence of the Secretary at any meeting of the
shareholders or his inability to act as Secretary, the presiding officer may
appoint any person to act as Secretary of the meeting.

meeting of shareholders shall request the appointment of inspectors, a majority
of the shareholders present at such meeting and entitled to vote thereat shall
appoint inspectors who need not be shareholders. If the right of any person to
vote at such meeting shall be challenged, the inspectors of election shall
determine such right. The inspectors shall receive and count the votes either
upon an election or for the decision of any question and shall determine the
result. A writing by the inspectors certifying any vote shall be prima facie
evidence thereof.

shareholder in the Corporation shall be deemed to assent to these Bylaws, and
shall designate to the Secretary the address to which he desires that the notice
herein required to be given may be sent; and all notices mailed to such

permitted to be taken by the shareholders at any annual or special meeting may
be taken by a writing signed by all of the shareholders indicating their
unanimous consent.

successors are elected and qualified, or until their resignation or removal.

                  SECTION 2. PLACE OF MEETING. The Directors may hold their
meetings in such place or places within or without this State as a majority of

of Directors. Directors shall be notified in writing, personally or by telephone
of the time, place and purpose of all meetings of the Board at least three days

waived such notice by his attendance at any meeting.

                  SECTION 4. QUORUM. A majority of the Board of Directors shall
constitute a quorum for the transaction of business; and if at any meeting of

ordered by the Board of Directors or by Bylaw.

                  SECTION 7. ACTION WITHOUT MEETING. Any action required or
permitted to be taken by the Board of Directors at any regular, annual, or
special meeting may be taken by the Directors by a writing signed by all of the

and/or until their successors are chosen. No one of such officers need be a
director. Any two of the above offices, except those of President and
Vice-President, may be held by the same person, but no officer shall execute,
acknowledge, or verify any instrument in more than one capacity. The Board of
Directors may fix the salaries of the officers of the Corporation.

                  SECTION 2. The Board of Directors may also appoint such other
officers and agents as it may deem necessary for the transaction of the business
of the Corporation. All officers and agents shall respectively have such
authority and perform such duties in the management of the property and affairs
of the Corporation as may be designated by the Board of Directors. Any officer
or agent may be removed, or any vacancies filled, by the Board of Directors

executive officer of the Corporation, and in the recess of the Board of
Directors shall have the general control and management of its business and
affairs, subject, however, to the right of the Board of Directors to delegate
any specific power to any other officer or officers of the Corporation, except
such as may be by statute exclusively conferred upon the President.

                  SECTION 2. VICE-PRESIDENT. In case the office of President
shall become vacant by death, resignation, or otherwise, or in case of the

office, such duties shall, for the time being, devolve upon the Vice-President
designated by the Board, who shall do and perform such other acts as the Board
of Directors may, from time to time, authorize him to do.

                  SECTION 3. TREASURER. The Treasurer shall have custody and
keep account of all money, funds and property of the Corporation, unless
otherwise determined by the Board of Directors, and he shall render such
accounts and present such statements to the Directors and President as may be
required of him. He shall deposit all funds of the Corporation which may come
into his hands in such bank or banks as the Board of Directors may designate. He
shall keep all bank accounts in the name of the Corporation and shall exhibit
his books and accounts, at all reasonable times, to any Director of the
Corporation upon application at the office of the Corporation during business
hours. He shall pay out money as the business may require upon the order of the
properly constituted officer or officers of the Corporation, taking proper
vouchers therefor; provided, however, that the Board of Directors shall have the
power by resolution to delegate any of the duties of the Treasurer to other
officers, and to provide by what officers, if any, all bills, notes, checks,
vouchers, orders or other instruments shall be countersigned. He shall perform,
in addition, such other duties as may be delegated to him by the Board of
Directors.

                  SECTION 4. SECRETARY. The Secretary of the Corporation shall
keep the minutes of all the meetings of the shareholders and Board of Directors
in books provided for that purpose. He shall attend to the giving and receiving
of all notices of the Corporation. He shall have charge of the stock books and
such other books and records as the Board of Directors may direct, all of which,
shall at all reasonable times be open to the examination of any Director upon
application at the office of Secretary. He shall perform, in addition, such
other duties as may be delegated to him by the Board of Directors.

                                                                               5

be given to the shareholders, to directors, or to any officer of the
Corporation, shall be deemed to be sufficiently given by depositing the same in
a post office box, in a sealed, post-paid wrapper, addressed to such
shareholder, director, or officer at his last known address, and such notice
shall be deemed to have been given at the time of such mailing.

add to or repeal these Bylaws by majority vote, or by a writing signed by all of
the shareholders or all of the directors indicating their unanimous consent,
including the fixing and altering of the Board of Directors; provided that the
Board of Directors shall not make or alter any Bylaws fixing their
qualifications, classification, or term of office.
