     The following documents have been filed with the Securities and Exchange
Commission by Heritage Financial Corporation (the "Company") and are
incorporated herein by reference and made a part hereof:

1.   The Company's Annual Report on Form 10-K for the six month period ended
     December 31, 1998, provided that any information included or incorporated
     by reference in response to Items 402(a)(8), (i), (k) or (l) of Regulation
     S-K of the Securities and Exchange Commission shall not be deemed to be
     incorporated herein and is not a part of the Registration Statement.

2.   The description of the Common Stock of the Company contained in the
     Company's Registration Statement on Form 8-A filed with the Commission.

3.   All reports filed by the Company pursuant to Section 13 or 15(d) of the
     Securities Exchange Act of 1934 since the end of the fiscal year covered by
     the financial statements in the Annual Report on Form 10-K referred to in
     paragraph 1 above, including the Company's Quarterly Reports on Form 10-Q
     for the three month periods ended March 31, 1999 and June 30, 1999.

4.   All documents filed by the Company pursuant to Sections 13(a), 13(c), 14
     and 15(d) of the Securities Exchange Act of 1934 subsequent to the date
     hereof and prior to the filing of a post-effective amendment which
     indicates that all securities offered hereby have been sold or which
     deregisters all securities then remaining unsold, shall be deemed to be
     incorporated by reference herein and to be part hereof from the date of the
     filing of such documents. Any statement contained in a document
     incorporated by reference herein and filed prior to the filing hereof

                                       2


     shall be deemed to be modified or superseded for purposes of this
     Registration Statement to the extent that a statement contained herein
     modifies or supersedes such statement, and any statement contained herein
     or in any other document incorporated by reference herein shall be deemed
     to be modified or superseded for purposes of this Registration Statement to
     the extent that a statement contained in any other subsequently filed
     document which also is incorporated by reference herein modifies or
     supersedes such statement. Any such statement so modified or superseded
     shall not be deemed, except as so modified or superseded, to constitute a
     part of this Registration Statement.

     The Heritage Financial Corporation 401(k) Employee Stock Ownership Plan is
an amendment to the Heritage Bank Employee Stock Ownership Plan ("ESOP")
effective October 1, 1999.  The ESOP did not file its general reports with the
Securities and Exchange Commission.  The Heritage Financial Corporation 401(k)
Employee Stock Ownership Plan has not completed its first fiscal year and has
not been in existence for 90 days prior to the filing of this Statement.

ITEM 4.  DESCRIPTION OF SECURITIES

     Plan interests under the Heritage Financial Corporation 401(k) Employee
Stock Ownership Plan are being registered hereunder. All shares of Company stock
purchased by this Plan will be previously issued shares purchased by the Plan
Trustee in the open market.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

     Attorneys who are members or who are employed by Gerrish & McCreary, P.C.,
who have provided advice with respect to this matter in the aggregate own,
directly and indirectly 10,000 shares of the Common Stock of the Company.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Washington Business Corporation Act, RCW Chapter 23B.08, authorizes
indemnification of directors, officers and employees under certain
circumstances. The Company's Articles of Incorporation provide, among other
things, for the indemnification of directors and authorize the Board to pay
reasonable expenses incurred by, or to satisfy a judgment or fine against a
current or former director in connection with any personal legal liability
incurred by the individual while acting for the Company within the scope of his
or her employment, and which was not the result of conduct finally adjudged to
be "egregious" conduct. "Egregious" conduct is defined as intentional
misconduct, a knowing violation of law, or participation in any transaction from
which the person will personally receive a benefit in money, property or
services to which that person is not legally entitled. The Articles of

                                       3


Incorporation also include a provision that limits the liability of directors of
the Company from any personal liability to the Company or its shareholders for
conduct not found to have been egregious.  The Company has purchased an officers
and directors liability insurance policy which provides for insurance of
directors and officers of the Company against certain liabilities they may incur
in their capacities as such.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED

     Not applicable.

ITEM 8.  EXHIBITS

     See the Exhibit Index which is incorporated herein by reference.

     The Company undertakes to cause the Heritage Financial Corporation 401(k)
Employee Stock Ownership Plan and any amendments thereto to be submitted to the
Internal Revenue Service ("IRS") in a timely manner and will make all changes
required by the IRS in order to qualify the Plan.

ITEM 9.  UNDERTAKINGS

(a)  The Company hereby undertakes:

     (1)  To file, during any period in which offers or sales are being made,
          a post-effective amendment to this Registration Statement:

          (i)  to include any prospectus required by Section 10(a)(3) of the
               Securities Act of 1933;

          (ii) to reflect in the prospectus any facts or events arising after
               the effective date of this Registration Statement (or the most
               recent post-effective amendment thereof) which, individually or
               in the aggregate, represent a fundamental change in the
               information set forth in the Registration Statement;

         (iii) to include any material information with respect to the plan of
               distribution not previously disclosed in this Registration
               Statement or any material change to such information in this
               Registration Statement;

               Provided, however, that paragraph (a)(1)(i) and (a)(1)(ii) shall
               not apply if the Registration Statement is on Form S-3, Form S-8
               or

                                       4


               Form F-3 and the information required to be included in a post-
               effective amendment by those paragraphs is contained in periodic
               reports filed by the Company pursuant to Section 13 or Section
               15(d) of the Securities Exchange Act of 1934 that are
               incorporated by reference in this Registration Statement.

     (2)  That, for the purpose of determining any liability under the
          Securities Act of 1933, each such post-effective amendment shall be
          deemed to be a new Registration Statement relating to the securities
          offered therein and the offering of such securities at that time shall
          be deemed to be the initial bona fide offering thereof.

     (3)  To remove from registration by means of a post-effective amendment any
          of the securities being registered which remain unsold at the
          termination of the offering.

(b)  The undersigned Company hereby undertakes that, for purposes of determining
     any liability under the Securities Act of 1933, each filing of the
     Company's Annual Report pursuant to Section 13(a) or Section 15(d) of the
     Securities Exchange Act of 1934 (and, where applicable, each filing of an
     employee benefit plan's annual report pursuant to Section 15(d) of the
     Securities Exchange Act of 1934) that is incorporated by reference in this
     Registration Statement shall be deemed to be a new registration statement
     relating to the securities offered therein, and the offering of such
     securities at that time shall be deemed to be the initial bona fide
     offering thereof.

(c)  Insofar as indemnification for liabilities arising under the Securities Act
     of 1933 may be permitted to directors, officers and controlling persons of
     the Company pursuant to the foregoing provisions or otherwise, the Company
     has been advised that, in the opinion of the Securities and Exchange
     Commission, such indemnification is against public policy as expressed in
     the act and is, therefore, unenforceable.  In the event that a claim for
     indemnification against such liabilities (other than the payment by the
     Company of expenses incurred or paid by a director, officer or controlling
     persons of the Company in the successful defense of any action, suit or
     proceeding) is asserted by such director, officer or controlling persons in
     connection with the securities being registered, the Company will, unless
     in the opinion of its counsel the matter has been settled by controlling
     precedent, submit to a court of appropriate jurisdiction the question
     whether such indemnification by it is against public policy as expressed in
     the Act and will be governed by the final adjudication of such issue.

                                       5
