- --------------------------------------------------------------------------------

Individual- The Stock is to be registered in an individual's  name only. You may
not list beneficiaries for this ownership.

Joint Tenants- Joint tenants with right of  survivorship  identifies two or more
owners.  When  stock is held by  joint  tenants  with  rights  of  survivorship,
ownership  automatically  passes to the surviving joint tenant(s) upon the death
of any joint tenant. You may not list beneficiaries for this ownership.

Tenants in Common- Tenants in common may also identify two or more owners.  when
stock is to be held by  tenants  in  common,  upon the  death of one  co-tenant,
ownership  of the stock will be held by the  surviving  co-tenant(s)  and by the
heirs of the deceased co-tenant.  All parties must agree to the transfer or sale
of shares  held by tenants in common.  You may not list  beneficiaries  for this
ownership.

Individual Retirement Account- Individual Retirement Account ("IRA") holders may
make   stock   purchases   from   their   deposits    through   a   pre-arranged
"trustee-to-trustee"  transfer.  Stock may only be held in a self-directed  IRA.
The Advance  Financial  Savings Bank does not offer a self-directed  IRA. Please
contact the Stock  Information  Center if you have any questions  about your IRA
account or to obtain a list of local brokers who will open a self-directed  IRA,
or check with your broker.  There will be no early  withdrawal  or IRS penalties
incurred by these transactions.

Uniform Gift to Minors- For  residents of many states,  stock may be held in the
name of a custodian  for the  benefit of a minor  under the Uniform  Transfer to
Minors Act. For residents in other  states,  stock may be held in a similar type
of ownership under the Uniform Gift to Minors Act of the individual  states. For
either  ownership,  the minor is the  actual  owner of the stock  with the adult
custodian  being  responsible  for the investment  until the child reaches legal
age.

Instructions:  See your  legal  advisor  if you are  unsure  about  the  correct
registration of your stock.

On the first  line,  print the first name,  middle  initial and last name of the
custodian,  with the  abbreviation  "CUST" after the name. Print the first name,
middle  initial and last name of the minor on the second  "NAME" line.  Only one

purchase limitations.

Fiduciary/Trust-  Generally,  fiduciary  relationships (such as Trusts, Estates,
Guardianships,  etc.) are  established  under a form of trust  agreement  or are
pursuant to a court order.  Without a legal  document  establishing  a fiduciary
relationship, your stock may not be registered in a fiduciary capacity.

Instructions: On the first "NAME" line, print the first name, middle initial and
last name of the fiduciary if the fiduciary is an  individual.  If the fiduciary
is a corporation,  list the corporate title on the first "NAME" line.  Following

representative, etc.

On the second "NAME" line, print either the name of the maker, donor or testator
OR the name of the beneficiary.  Following the name,  indicate the type of legal
document establishing the fiduciary relationship (agreement, court order, etc.).

governing the relationship.  The date of the document need not be provided for a
