Item 1.           Changes in Control of Registrant.
                  ---------------------------------



         On June 21, 1996,  Westport Bancorp,  Inc. (the "Company") entered into
an  Agreement  and Plan of Merger (the  "Agreement")  by and among  HUBCO,  Inc.
("HUBCO"),  the Company and The  Westport  Bank & Trust  Company  (the  "Bank").
Pursuant to the Agreement,  at the Effective Time (as defined in the Agreement),
the Company  shall be merged with and into HUBCO (the  "Merger") and HUBCO shall
be the surviving  corporation.  At HUBCO's  option,  at the Effective  Time, and
simultaneously  with the Merger,  the Bank shall be merged  (the "Bank  Merger")
with HUBCO's principal  Connecticut bank subsidiary (the  "Connecticut  Bank" or
the "Surviving Bank").

         Pursuant to the Agreement,  in the Merger,  each share of common stock,
$.01 par value,  of the Company  ("WBI Common  Stock"),  issued and  outstanding
immediately  prior to the  Effective  Time  (other  than  dissenting  shares and
excluding  treasury  shares and shares held by HUBCO)  shall be converted at the
Effective Time into the right to receive  0.3225 of a share of common stock,  no
par value, of HUBCO ("HUBCO Common  Stock").  Each share of Series A Convertible
Preferred Stock, $.01 par value, of the Company ("WBI Preferred Stock"),  issued
and  outstanding  immediately  prior to the Effective Time  (excluding  treasury
shares,  shares held by HUBCO and  dissenting  shares) shall be converted at the
Effective  Time into the right to receive one share of a newly created series of
HUBCO preferred stock having terms substantially identical to those set forth on
Exhibit 2.1(a) to the Agreement. Cash shall be paid in lieu of fractional shares
of HUBCO Common Stock.

         Stock options  which,  as of the Effective  Time, are  outstanding  and
fully  vested and  exercisable  as to all of the shares of WBI Common Stock that
are subject to such option  (including  options  that  became  exercisable  as a
result of the transactions  contemplated by the Agreement) (each a "Vested Stock
Option") shall be converted at the Effective Time into HUBCO Common Stock to the
extent  permitted  under the plans and agreements  under which such Vested Stock
Options were granted (each Vested Stock Option so converted, a "Converting Stock
Option"). Each stock option outstanding at the Effective Time (i) which is not a
Vested  Stock  Option or (ii) which is a Vested  Stock Option and which is not a
Converting  Stock  Option shall be  converted  into an option to purchase  HUBCO
Common Stock.  At the  Effective  Time,  each warrant to purchase  shares of WBI
Common Stock which is  outstanding at the Effective Time shall be converted into
a like warrant to purchase HUBCO Common Stock.

         The Agreement provides that two nominees, designated by the Company and
acceptable to HUBCO (which persons shall be Michael H. Flynn and David A. Rosow,
unless HUBCO and the Company shall agree in writing to the  contrary),  
<PAGE>

shall be duly  appointed by the Board of Directors of HUBCO to HUBCO's  Board of
Directors  effective at the Effective Time.  Provision shall have been made such
that three  nominees,  designated by the Company and  acceptable to HUBCO (which
persons shall include Michael H. Flynn and David A. Rosow,  unless HUBCO and the
Company agree in writing to the contrary) and one person designated by Josiah T.
Austin and  acceptable  to HUBCO each shall have been  appointed as directors of
the  Surviving  Bank (or shall  continue  as  directors  of the Bank if the Bank
Merger is not consummated at the Effective Time). HUBCO also shall cause Michael
H. Flynn to be elected  President of the Connecticut  Bank and David A. Rosow to
be  appointed  Chairman  of the  Executive  Committee  of  the  HUBCO  Board  of
Directors.

         The  Agreement  is attached as Exhibit 2 hereto,  and  incorporated  by
reference herein.
