         Tri-County Bancorp,  Inc., a Wyoming  corporation (the "Company"),  has
appointed  us to act as  Information  Agent  in  connection  with  its  offer to
purchase  up to 313,000  shares of its Common  Stock,  par value $0.10 per share
(the  'shares"),  at prices,  net to the seller in cash, not greater than $14.00
nor less than $11.00 per Share,  specified by tendering  stockholders,  upon the
terms and subject to the  conditions  set forth in its Offer to Purchase,  dated
October  23,  1998,  and the  related  Letter  of  Transmittal  (which  together
constitute the "Offer").

         The Company will,  upon the terms and subject to the  conditions of the
Offer, determine a single per Share price (not greater than $14.00 nor less than
$11.00 per Share) that it will pay for Shares validly tendered and not withdrawn
pursuant to the Offer (the "Purchase Price"),  taking into account the number of
Shares so tendered  and the prices  specified  by  tendering  stockholders.  The
Company  will select the lowest  Purchase  Price which will allow it to purchase
313,000 Shares (or such lesser number of Shares as are validly  tendered and not
withdrawn  at prices not  greater  than  $14.00 nor less than  $11.00 per Share)
pursuant  to the  Offer,  or such  greater  number as the  Company  may elect to
purchase.  All Shares  validly  tendered and not withdrawn at prices at or below
the Purchase Price will be purchased at the Purchase Price, net to the seller in
cash,  upon the terms and subject to the conditions of the Offer,  including the
proration terms thereof.  See "The Offer -- Number of Shares;  Proration" in the
Offer to Purchase.

          If,  prior  to  the  Expiration  Date  (as  defined  in the  Offer  to
Purchase), more than 313,000 Shares are validly tendered and not withdrawn at or
below the Purchase  Price,  the Company will,  upon the terms and subject to the
conditions  of the Offer,  buy Shares first from all Odd Lot Holders (as defined
in the Offer to  Purchase)  who  validly  tender and do not  withdraw  all their
Shares at or below the  Purchase  Price  and then on a pro rata  basis  from all
other  stockholders  whose Shares are validly  tendered and not  withdrawn at or
below the Purchase Price.

          The  Offer is  conditioned  upon,  among  other  things,  the  Company
obtaining the funds  necessary to consummate  the Offer and pay all related fees
and expenses.  The Offer is not  conditioned  upon any minimum  number of Shares
being tendered.  See "The Offer -- Certain Conditions of the Offer" in the Offer
to Purchase.
