succeeding day not a legal holiday, for the purpose of electing directors of the
company to serve during the ensuing year and for the transaction of such other

     At least ten (10) days' written notice specifying the time and place, when 
and where, the annual meeting shall be convened, shall be mailed in a United 
States Post Office addressed to each of the stockholders of record at the time 
of issuing the notice at his or her, or its address last known, as the same

          SECTION 2. Special meetings of the stockholders may be held at the 
office of the company in the State of Nevada, or elsewhere, whenever called by 
the President, or by the Board of Directors, or by vote of, or by an instrument

outstanding capital stock of the company. At least ten days' written notice of 
such meeting, specifying the day and hour and place, when and where such 
meeting shall be convened, and objects for calling the same, shall be mailed in

of the company, may be transacted at any special meeting or at any adjournment 
thereof. Only such business, however, shall be acted upon at special meeting of

shall fail to attend, in person or by proxy, at the time and place fixed by 
these By-Laws for any annual meeting, or fixed by a notice as above provided

quorum shall be present, any business may be transacted which might have been 
transacted as originally called.

          SECTION 6. At such meeting of the stockholders every stockholder shall
be entitled to vote in person or by his duly authorized proxy appointed by
