Item 5.  Other Events.
         -------------

         On July 15, 1997, the Board of Directors of Advance  Financial  Bancorp
(the  "Company")  declared a dividend of one Preferred  Share  Purchase Right (a
"Right") for each  outstanding  share of common stock,  par value $.10 per share
(the "Common Shares"),  of the Company. The dividend is payable on July 31, 1997
(the  "Record  Date") to the  stockholders  of record on that  date.  Each Right
entitles the registered holder to purchase from the Company one one-hundredth of
a share of the Company's Junior  Participating  Preferred  Stock,  Series A, par
value  $.10  per  share  ("Preferred   Shares")  at  a  price  of  $37  per  one
one-hundredth  of  a  Preferred  Share  (the  "Purchase   Price"),   subject  to
adjustment.  The  description  and terms of the Rights are set forth in a Rights
Agreement (the "Rights  Agreement")  between the Company and American Securities
Transfer & Trust, Incorporated, as Rights Agent (the "Rights Agent").

         Until  the  earlier  to  occur  of  (i)  10  days  following  a  public
announcement  that a person or group of  affiliated  or  associated  persons (an
"Acquiring  Person")  have acquired  beneficial  ownership of 15% or more of the
outstanding  Common  Shares or more than such  person or group  held on July 31,
1997 if such person or group held 15% or more of the  outstanding  Common Shares
on such date or (ii) 10 business  days (or such later date as may be  determined
by action of the Board of Directors  prior to such time as any Person becomes an
Acquiring Person) following the commencement of, or announcement of an intention
to make, a tender offer or exchange offer the consummation of which would result
in the  beneficial  ownership  by a  person  or  group  of 15% or  more  of such
outstanding Common Shares or more than such person held on July 31, 1997 if such
person or group held 15% or more of the  outstanding  Common Shares on such date
(the earlier of such dates being  called the  "Distribution  Date"),  the Rights
will  be  evidenced,  with  respect  to  any of the  Common  Share  certificates
outstanding as of the Record Date, by such Common Share  certificate with a copy
of the Summary of Rights attached thereto.

         The Rights Agreement  provides that,  until the Distribution  Date, the
Rights  will be  transferred  with and only with the  Common  Shares.  Until the
Distribution  Date (or earlier  redemption  or  expiration  of the Rights),  new
Common Share  certificates  issued after the Record Date,  upon  transfer or new
issuance  of Common  Shares  will  contain a notation  incorporating  the Rights
Agreement by reference.  Until the Distribution  Date (or earlier  redemption or
expiration of the Rights),  the surrender for transfer of any  certificates  for
Common Shares,  outstanding as of the Record Date, even without such notation or
a copy of the Summary of Rights being attached thereto, will also constitute the
transfer of the Rights  associated  with the Common Shares  represented  by such
certificate.  As soon as practicable  following the Distribution Date,  separate
certificates  evidencing  the Rights  ("Right  Certificates")  will be mailed to
holders  of record of the  Common  Shares  as of the  close of  business  on the
Distribution Date and such separate Right  Certificates  alone will evidence the
Rights.







         The Rights are not exercisable until the Distribution  Date. The Rights
will  expire on July 17, 2007 (the "Final  Expiration  Date"),  unless the Final
Expiration  Date is extended  or unless the Rights are  earlier  redeemed by the
Company, in each case, as described below.

         The Purchase Price payable, and the number of Preferred Shares or other
securities  or  property  issuable,  upon  exercise of the Rights are subject to
adjustment  from time to time to  prevent  dilution  (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Preferred
Shares, (ii) upon the grant to holders of the Preferred Shares of certain rights
or  warrants  to  subscribe  for or  purchase  Preferred  Shares at a price,  or
securities  convertible into Preferred Shares with a conversion price, less than
the  then  current  market  price of the  Preferred  Shares  or  (iii)  upon the
distribution to holders of the Preferred  Shares of evidences of indebtedness or
assets  (excluding  regular  periodic  cash  dividends  paid out of  earnings or
retained  earnings or  dividends  payable in Common  Shares) or of  subscription
rights or warrants (other than those referred to above).

         The number of outstanding  Rights and the number of one  one-hundredths
of a Preferred  Share  issuable  upon exercise of each Right are also subject to
adjustment  in the  event  of a stock  split  of the  Common  Shares  or a stock
dividend  on the  Common  Shares  payable  in  Common  Shares  or  subdivisions,
consolidations or combinations of the Common Shares occurring, in any such case,
prior to the Distribution Date.

         Preferred  Shares  purchasable  upon exercise of the Rights will not be
redeemable.  Each  holder of a  Preferred  Share will be  entitled  to a minimum
preferential  quarterly dividend payment equal to the greater of $1 per share or
100 times the dividend  declared per Common Share.  In the event of liquidation,
each  holder of a  Preferred  Share will be  entitled to the greater of $100 per
share or 100 times the payment made per Common Share.  Each Preferred Share will
have 100 votes, voting together with the Common Shares. Finally, in the event of
any  merger,  consolidation  or other  transaction  in which  Common  Shares are
exchanged, each Preferred Share will be entitled to receive 100 times the amount
received per Common Share. These rights are protected by customary  antidilution
provisions.

         Because of the nature of the Preferred Shares' dividend and liquidation
rights,  the  value  of the one  one-hundredth  interest  in a  Preferred  Share
purchasable  upon exercise of each Right should  approximate the long term value
of one Common Share.

         In the event that the Company is acquired in a merger or other business
combination  transaction  or 50% or more of its  consolidated  assets or earning
power are sold,  proper  provision  will be made so that each  holder of a Right
will thereafter have the right to receive, upon the exercise thereof at the then
current  exercise  price of the Right,  that number of shares of common stock of
the acquiring  company which at the time of such  transaction will have a market
value of two times the exercise price of the Right. In the event that any person
or group of affiliated or associated  persons becomes an Acquiring Person proper
provision  shall be made so that  each  holder  of a Right,  other  than  Rights
beneficially owned by the Acquiring Person (which will thereafter be void), will
thereafter  have the right to receive upon exercise that number of Common Shares
having a market value of two times the exercise price of the Right.







         At any time after the acquisition by a person or group of affiliated or
associated  persons of  beneficial  ownership of 15% or more of the  outstanding
Common  Shares and prior to the  acquisition  by such  person or group of 50% or
more of the outstanding Common Shares, the Board of Directors of the Company may
exchange the Rights  (other than Rights owned by such person or group which have
become void),  in whole or in part, at an exchange  ratio of one Common Share or
one one-hundredth of a Preferred Share per Right (subject to adjustment).

         With certain  exceptions,  no adjustment in the Purchase  Price will be
required until  cumulative  adjustments  require an adjustment of at least 1% in
such Purchase Price. No fractional  Preferred  Shares will be issued (other than
fractions which are integral multiples of one one-hundredth of a Preferred Share
and which may, at the  election  of the  Company,  be  evidenced  by  depositary
receipts) and in lieu  thereof,  an adjustment in cash will be made based on the
market  price of the Common  Shares on the last trading day prior to the date of
exercise.

         At any time prior to the acquisition by a person or group of affiliated
or associated persons of beneficial  ownership of 15% or more of the outstanding
Common  Shares,  the Board of  Directors of the Company may redeem the Rights in
whole, but not in part, at a price of $.01 per Right (the  "Redemption  Price").
The  redemption  of the Rights may be made  effective at such time on such basis
and with such  conditions as the Board of Directors in its sole  discretion  may
establish.  Immediately upon any redemption of the Rights, the right to exercise
the Rights will terminate and the only right of the holders of Rights will be to
receive the Redemption Price.

         The terms of the Rights may be amended by the Board of Directors of the
Company without the consent of the holders of the Rights, including an amendment
to lower certain  thresholds  described  above,  except that from and after such
time as any person  becomes an Acquiring  Person no such amendment may adversely
affect the interests of the holders of the Rights.

         Until a Right is exercised,  the holder thereof,  as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends.
