                       GUIDELINES FOR REGISTERING STOCK
 
  For reasons of clarity and standardization, the stock transfer industry has
  developed uniform stockholder registrations which we will utilize in the
  issuance of your Heritage Financial Stock Certificate(s). If you have any
  questions, please consult your legal advisor.
  Stock ownership must be registered in one of the following manners:
 
- ------------------------------------
INDIVIDUAL: Avoid the use of two initials. Include the first given name,
            middle initial and last name of the stockholder. Omit words of
            limitation that do not affect ownership rights such as "special
            account," "single man," "personal property," etc. If the stock is
            held individually upon the individual's death, the stock will be
            owned by the individual's estate and distributed as indicated by
            the individual's will or otherwise in accordance with law.
 
- ------------------------------------
JOINT:      Joint ownership of stock by two or more persons shall be inscribed
            on the certificate with one of the following types of joint
            ownership. Names should be joined by "and"; do not connect with
            "or." Omit titles such as "Mrs.," "Dr.," etc.
            JOINT TENANTS--Joint Tenancy with Right of Survivorship and not as
            Tenants in Common may be specified to identify two or more owners
            where ownership is intended to pass automatically to the surviving
            tenant(s).
            TENANTS IN COMMON--Tenants in Common may be specified to identify
            two or more owners. When stock is held as tenancy 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 in this form of ownership.
 
- ------------------------------------
UNIFORM     Stock may be held in the name of a custodian for a minor under the
TRANSFER    Uniform Transfers to Minors laws of individual states. There may
TO MINORS:  be only one custodian and one minor designated on a stock
            certificate. The standard abbreviation of custodian is "CUST,",
            while the description "Uniform Transfers to Minors Act" is
            abbreviated "UNIF TRAN MIN ACT." Standard U.S. Postal Service
            state abbreviations should be used to describe the appropriate
            state. For example, stock held by John P. Jones under the Uniform
            Transfers to Minors Act will be abbreviated:
 
                 JOHN P. JONES CUST SUSAN A. JONES
                 UNIF TRAN MIN ACT WA
 
- ------------------------------------

            1. The name(s) of the fiduciary:
                 --If an individual, list the first given name, middle
                 initial, and last name.
                 --If a corporation, list the corporate title.
                 --If an individual and a corporation, list the corporation's
                 title before the individual.

                 --Custodian
            3. The type of document governing the fiduciary relationship.
               Generally, such relationships are either under a form of living
               trust agreement or pursuant to a court order. Without a
               document establishing a fiduciary relationship, your stock may
               not be registered in a fiduciary capacity.
            4. The date of the document governing the relationship. The date
               of the document need not be used in the description of a trust
               created by a will.
            5. Either of the following:
                        The name of the maker, donor or testator
