                           SISTERSVILLE BANCORP, INC.

         The shares  represented by this certificate are subject to a limitation
contained  in  the  certificate  of   incorporation   of  the  corporation  (the
"Certificate")  to the effect  that in no event  shall any  record  owner of any
outstanding common stock which is beneficially owned, directly or indirectly, by
a person who  beneficially  owns in excess of 10% of the  outstanding  shares of
common  stock ( the  "Limit") be entitled or permitted to any vote in respect of
shares  held in excess of the Limit and may have  their  voting  rights  reduced
below the  Limit.  In  addition,  for five years  from the  initial  sale of the
corporation's  common stock, no person or entity may offer to acquire or acquire
over 10% of the then outstanding shares of any class of equity securities of the
corporation.

         The  Board  of  Directors  of  the   corporation   is   authorized   by
resolution(s),  from time to time adopted, to provide for the issuance of serial
preferred stock in series and to fix and state the voting powers,  designations,
preferences, and relative,  participating,  optional, or other special rights of
the  shares  of each  such  series  and  the  qualifications,  limitations,  and
restrictions  thereof.  The  corporation  will furnish to any  shareholder  upon
request and  without  charge a full  description  of each class of stock and any
series thereof.

         The shares  represented  by this  certificate  may not be  cumulatively
voted in the election of  directors of the  corporation.  The  Certificate  also
includes a provision  the effect of which is to require the approval of not less
than 80% of the corporation's  voting stock prior to the corporation engaging in
certain business  combinations (as defined in the Certificate) with a person who
is the beneficial owner of 10% or more of the corporation's  outstanding  voting
stock,  or with an  affiliate  or associate  of the  corporation  (a  "Principal
Stockholder"). This restriction does not apply if certain approvals are obtained
from the Board of  Directors.  The  affirmative  vote of  holders  of 80% of the
outstanding  shares  of  capital  stock  of the  corporation  entitled  to  vote
generally in the election of directors  (considered for this purpose as a single
class)  is  required  to  amend  this  and  certain  other   provisions  of  the
Certificate.

of this certificate,  shall be construed as though they were written out in full
