FACTS
- -----

Heritage Financial Corporation, MHC (the "Mutual Holding Company") is a state-
chartered mutual holding company organized in the state of Washington.  The
Mutual Holding Company maintains its books on the accrual method of accounting
and files a tax return on a June 30 year end basis.  As a mutual holding
company, the Mutual Holding Company has no capital stock.

Heritage Savings Bank (the "Bank") is a state-chartered stock savings bank
organized in Washington.  The Mutual Holding Company owns approximately 66.3
percent of the issued and outstanding stock of the Bank.  The remaining 33.7
percent of the Bank's stock is held by the public.

The Mutual Holding Company and the Bank were organized on January 31, 1994 in
connection with the reorganization of Heritage Bank, a Mutual Savings Bank, (the
"Mutual Bank") from a state mutual savings bank into the Mutual Holding Company
(the "1994 Reorganization").  In June of 1993 the Bank received rulings from the
Internal Revenue Service (the "Service") holding that the 1994 Reorganization
constituted a tax-free transaction under Section 351 of the Code.  The Bank
issued common stock to the Mutual Holding Company in exchange for substantially
all of the assets and all of the liabilities of the Mutual Bank.  As part of the
1994 Reorganization, the Bank issued a portion of its stock to the public in
exchange for cash whereby immediately after the 1994 Reorganization the public
owned approximately 33.3 percent of the outstanding Bank Stock and the Mutual
Holding Company owned the remaining 66.7 percent.

The principal business of the Bank is the acceptance of savings deposits from
the general public and originating for sale or investment purposes first
mortgage loans on residential properties located in western Washington.  The
Bank also makes residential construction loans, income property loans, business
loans, consumer loans and second mortgage loans.  The Bank's income is derived
largely from interest and fees in connection with its lending activities.  Its
principal expenses are interest paid on savings deposits and operating expenses.

Currently, the management of the Bank and the Mutual Holding Company believe it
would be in their best interest, as well as the best interest of their
stockholders and members (respectively) to operate in the corporate structure
specified below.  The proposed transactions will result in the Bank being wholly
owned by Heritage Financial Corporation, a capital stock corporation organized
under the state law of Washington (the "Holding Company"), which is a more
common structure and form of ownership than a mutual holding company.  The new
corporate structure would also provide greater organizational flexibility, and
enable the resulting institutions to increase their equity capital base
available for expansion of services, facilities, possible future acquisitions of
other financial institutions, possible diversification into other related
financial services activities, and enhance their ability to render services to
the public in a competitive manner.  In addition, the proposed transactions will
result in the raising of additional

capital for the Bank and the Holding Company. As well, the proposed transactions
have been structured to re-unite the accumulated earnings and profits tax
attribute retained by the Mutual Holding Company with the retained earnings of
the Bank through a tax-free reorganization. This would increase the Bank's
ability to pay dividends in the future.

The Bank and the Mutual Holding Company have adopted the Amended and Restated
Plan of Conversion and Reorganization of Heritage Financial Corporation, MHC
referred to herein as the "Plan of Conversion".  The Mutual Holding Company and
the Bank represent that the Plan of Conversion shall be submitted together with
all requisite material to the Washington Department of Financial Institutions,
Division of Banks (the "Division"), the Federal Deposit Insurance Corporation,
and the Board of Governors of the Federal Reserve System or the Federal Reserve
Bank of San Francisco.

For valid business reasons, as described above and in the prospectus to be used
in the public offerings of Holding Company Stock described herein
("Prospectus"), the present corporate structure of the Mutual Holding Company
and the Bank will be changed pursuant to the following proposed transactions:

   (1)  The Bank will form the Holding Company as a new, wholly owned, first
        tier subsidiary of the Bank.

   (2)  The Holding Company will form an interim corporation ("Interim Bank B")
        as a new, wholly owned first tier subsidiary that is a state-chartered
        stock bank.

   (3)  Pursuant to the Plan of Merger between the Mutual Holding Company and
        the Bank, the Mutual Holding Company will convert from the mutual form
        to a state interim stock bank ("Interim Bank A") and Interim Bank A will
        immediately merge with and into the Bank with the Bank being the
        surviving corporation ("Merger 1").  Pursuant to Merger 1, the common
        stock of the Bank which was previously held by the Mutual Holding
        Company will be canceled and eligible members of the Mutual Holding
        Company will receive an interest in a liquidation account (the "Bank
        Liquidation Interests") of the Bank in exchange for such member's
        interest in the Mutual Holding Company.

        The initial balance of the liquidation account will equal 66.31 percent
        of the Bank's total shareholder equity as reflected in its June 30, 1997
        statement of

        financial condition, which is the latest statement of financial
        condition expected to be contained in the Prospectus to be utilized in
        the Mutual Holding Company's mutual-to-stock conversion (the
        "Conversion") plus an amount equal to the aggregate amount of Bank
        Common Stock dividends waived by the Mutual Holding Company since
        January 1, 1994, when the Mutual Holding Company was formed, and the
        amount of assets other than Bank Common Stock (approximately $120,000)
        held by the Mutual Holding Company.

   (4)  Immediately following Merger 1, pursuant to the Plan of Reorganization
        among the Bank, the Holding Company and Interim Bank B, Interim Bank B
        will merge with and into the Bank, with the Bank surviving ("Merger 2").
        Merger 2 will be completed in accordance with applicable federal and
        state laws.  The stock of the Bank held by the public, which then will
        constitute all of the outstanding shares of the Bank, will automatically
        be converted into common stock of the Holding Company ("Holding Company
        Stock") based upon a exchange ratio which ensures that the public
        shareholders will own, in the aggregate, approximately the same
        percentage of stock of the Holding Company outstanding upon completion
        of the Conversion as the percentage of the stock of the Bank owned by
        them in the aggregate immediately prior to the consummation of the
        Conversion, before giving effect to (a) cash paid in lieu of issuing
        fractional shares of stock of the Holding Company, (b) an adjustment
        downward to reflect the aggregate amount of Bank Common Stock dividends
        waived by the Mutual Holding Company since January 1, 1994, when the
        Mutual Holding Company was formed and the amount of assets other than
        Bank Common Stock (approximately $120,000) held by the Mutual Holding
        Company, and (c) any shares of stock of the Holding Company purchased by
        such public stockholders in the offering described below.

   (5)  All of the shares of common stock of Interim Bank B held by the Holding
        Company shall be converted into one share of common stock of the Bank
        which will continue to be owned by the Holding Company.  The shares of
        Holding Company issued prior to the effective date of the conversion
        shall be canceled.

   (6)  Simultaneously with the consummation of Merger 2, the Holding Company
        will sell additional shares of Holding Company Stock, with priority

        Company, net of liabilities associated with such assets.  Following such
        conversion, Interim Bank A will continue to engage in its business in
        substantially the same manner as engaged in Mutual Holding Company prior
        to such Conversion.  Except for the Merger, as described above, Interim
        Bank A has no plan or intention to sell or otherwise dispose of any of
        its assets, except in the ordinary course of business.

   (3)  Compensation to be paid to the mutual owner-employees of Mutual Holding
        Company will be commensurate with the amounts paid to third parties
        bargaining at arm's length for similar services.

        interests in the liquidation account to be established constructively by
        Interim Bank A will equal or exceed 99 percent of the aggregate fair
        market value of all savings accounts in Bank as of the close of business
        on such date.

   (5)  No shares of Interim Bank A stock will be issued in the transaction.

        savings depositors or to the Holding Company stockholders.

   (9)  The liabilities of Mutual Holding Company, if any, assumed by Interim
        Bank A, plus the liabilities, if any, to which the transferred assets
        are subject were incurred by Mutual Holding Company in the ordinary
        course of its business.

        assets of Mutual Holding Company on a going concern basis will exceed
        the amount of its liabilities plus the amount of liability to which its
        assets are subject.

Representations related to Merger 1:
- ------------------------------------

   (1)  The fair market value of the Bank Liquidation Interests received by each
        Mutual Holding Company member will approximately equal  the fair market
        value of the Mutual Holding Company liquidation interests surrendered in
        Merger 1.


   (2)  To the best of the knowledge of management of the Mutual Holding
        Company, there is no plan on the part of any members of the Mutual
        Holding Company to reduce their ownership interest in the Bank
        Liquidation Interests to an interest having a value, as of the date of

   (5)  The Liabilities of the Mutual Holding Company assumed by the Bank and
        the liabilities to which the transferred assets of the Mutual Holding

   (6)  Following the transaction the Bank will continue the historic business

Representations related to Merger 2:

   (1)  The fair market value of the Holding Company Stock received by the Bank
        shareholders will approximately equal the fair market value of the Bank
        stock surrendered in Merger 2.

        on the part of any Bank stockholders to reduce their ownership interest

ANALYSIS
- --------

Momentary existence of Interim Bank A
- -------------------------------------

A question can be raised whether the brief existence of Stock Interim should be
respected.  If the existence is not respected, Bank could be treated as
acquiring the Mutual Holding Company assets directly from MHC.  However, because
the form of the state law mergers will be (a) merger of Mutual Holding Company
into Interim Bank A and (b) Interim Bank A into Bank, the acquisition may not
qualify under section 368(a)(1)(A) if there is no state law merger of Mutual
Holding Company directly into Bank.

Generally, a mere change in form that qualifies as a reorganization described by
section 368(a)(1)(F) will be treated separately from its surrounding steps.  For
example, in Rev. Rul. 69-516, 1969-2 C.B. 66, a corporation changed its state of
incorporation and then 



[LOGO OF KPMG PEAT MARWICK LLP]

Page 11 
The Boards of Directors
Heritage Financial Corporation, MHC
Heritage Savings Bank
October 27, 1997

transferred its assets to an other corporation solely for stock of the acquiring
corporation. The ruling respected the change of the state of incorporation of
the target corporation, notwithstanding the fact that the target immediately
transferred all of its assets to the acquiring corporation. Specifically, the
ruling holds that the change of the state of incorporation will be a
reorganization within the meaning of section 368(a)(1)(F) and the asset
acquisition by the second corporation will qualify under section 368(a)(1)(C).
Similarly, Rev. Rul. 96-29, 1996-1 C.B. 72, emphasizes that a section
368(a)(1)(F) reorganization will generally be viewed as separate from
surrounding transactions.

Accordingly, KPMG believes that the conversion of Mutual Holding Company into
Interim Bank A should be viewed separately from the merger of Interim Bank A
into Bank, notwithstanding the brief existence of Interim Bank A.  Under this
analysis, the conversion shall be analyzed under section 368(a)(1)(F) and the
downstream merger of Interim Bank A into Bank should be respected as a statutory
merger for purposes of section 368(a)(1)(A).

Rev. Proc. 94-76
- ----------------

Historically, a downstream merger of a parent into its subsidiary could qualify
as a reorganization.  See, e.g., Anna Gilmore v. Commissioner, 44 B.T.A. 881
(1941), acq. 1942-2 C.B. 2; George v. Commissioner, 26 T.C. 396 (1956) acq.
1956-2 C.B. 5; Rev. Rul. 78-47, 1978 C.B. 113; Rev. Rul 70-223, 190-1 C.B. 79;
and Rev. Rul. 85-197, 1985-2 C.B. 120; cf, G.C.M. 39404 (Apr. 15, 1982) (Service
permitted upstream merger of less than 80 percent owned subsidiary); see also
PLR 9506036 (Nov. 15, 1994).

However, the Service announced in Rev. Proc. 94-76, 1994-2 C.B. 825, that it
would not issue advance rulings in cases involving a combination by
reorganization of a parent and its less than 80 percent owned subsidiary.  The
revenue procedure explained that such cases were under extensive study by the
Service.  Following the Tax Reform Act of 1986, there was concern that the
disappearance of the parent's gain in its subsidiary stock may be inconsistent
with the repeal of the General Utilities doctrine (which generally requires a
corporation to recognize gain on a disposition of its assets).  The study
project considered whether the Service should address the disappearance of the
stock gain with regulations under section 337(d).  In Notice 96-6, 1996-5 I.R.B.
27,  the Service announced that combining transactions were no longer an area
under extensive study by the Service.  However, the Service still refuses to
issue advance rulings in the area.  See section 3.01(23) of Rev. Proc. 97-3
I.R.B. 84, 88.

Given the issuance of Rev. Proc. 94-76, a question may be raised whether the
downstream merger of Interim Bank A into Bank can qualify as a reorganization
because Interim Bank A owns less than 80 percent of Bank.  However, as evidenced
by the citations above, both the courts and the Service have agreed for over
half a century that downstream reorganizations such as Merger 1 can be bona fide
tax-free reorganizations.  Any change would present a change to an extremely
long standing principle of tax law.

It is noteworthy that Rev. Proc. 94-76 does not indicate any potential effective
date should the IRS decide to change this long standing tax principle.
Normally, when the IRS believes that change to a tax policy is required, it
announces an effective date to notify taxpayers that transactions after such
date may well suffer adverse tax consequences.  See, e.g., Notice 94-76, Notice
94-73, and Notice-87-14.  The Service could argue that because section 337(d)
grants the Service extremely broad authority to issue regulations to enforce
General Utilities repeal, it clearly has the authority to change the long
standing tax policy on downstream mergers.  It is also noteworthy that in over
ten years, the Service has not issued any regulation under section 337(d) that
would adversely impact the second merger.

Therefore, while the matter is not free from doubt, it is the professional
judgment of KPMG that because:

   (1)  Downstream mergers such as Merger 1 have been bona fide tax-free
        reorganizations for over 50 years;
   (2)  Rev. Proc. 94-76 merely announced a study project which was formally
        closed without any conclusion about a change in tax policy; and
   (3)  Rev. Proc. 94-76 does not announce any date regarding any potential
        change of tax policy;

any adverse change in tax policy regarding transactions such as the merger
occasioned by Rev. Proc. 94-76 will be prospective in effect.

Liquidation accounts as a class of stock
- ----------------------------------------

In order to qualify under section 368(a)(2)(E), Bank shareholders must receive
solely voting stock in Holding Company in exchange for an amount of Bank stock
constituting control of Bank.  Section 368(a)(2)(E)(ii).  Section 368(c) defines
control as 80 percent of stock possessing at least 80 percent of the total
combined voting power of all classes of stock entitled to vote and at least 80
percent of the total number of shares of all other

classes of stock of the corporation. Liquidation accounts of Bank will remain
outstanding after the acquisition of Bank by Holding Company. Accordingly, if
the liquidation accounts are treated as a class of non-voting stock of Bank, the
section 368(a)(2)(E)(ii) control requirement will not be satisfied in the
acquisition.

The Service has held that liquidation accounts can be treated as equity for
purposes of the continuity of proprietary interest requirement for corporate
reorganizations.  See Rev. Rul. 80-105, 80-1 C.B. 78.  Also, mutual interests
have been treated as stock in the context of a corporate acquisition.  See Rev.
Rul. 69-3, 1969-1 C.B. 1969-1 C.B. 103 (section 354 applies to the exchange of a
mutual interest in one corporation for a mutual interest in another).  While
acknowledging the role of a liquidation account as equity (Rev. Rul. 80-105),
the Service historically has not accorded liquidation accounts the status of
stock.

For example, in PLR 9510044 (March 10, 1995), a mutual holding company merged
downstream into its subsidiary bank.  The mutual owners received liquidation
accounts in the bank.  The newly formed holding company then acquired the bank
stock in a reverse triangular reorganization purporting to qualify under section
368(a)(2)(E).  The Service specifically held that it would disregard the
liquidation accounts in the bank for purposes of applying the control
requirement under section 368(a)(2)(E)(ii).  While a PLR may not be used or
cited as precedent pursuant to section 6110(j)(3) of the Code, it illustrates
the Service's analysis and position on this issue.

If Merger 1 and Merger 2 are consummated as described herein, based solely upon
information contained in the documents reviewed by us, and the FACTS and
REPRESENTATIONS above, KPMG renders the following opinions with respect to the
proposed transactions:

Conversion of Mutual Holding Company to Interim Bank A
- ------------------------------------------------------

   (1)  The conversion of Mutual Holding Company from a state mutual holding
        company to Interim Bank A, a state stock savings, as described above,
        should constitute a reorganization within the meaning of Section
        368(a)(1)(F) of the Code, and no gain or loss will be recognized to
        either the Mutual Holding Company or to Interim Bank A as a result of
        such conversion (Revenue Ruling 80-105, 1980-1 C.B. 78). The Mutual
        Holding Company and Interim Bank A will each be a party to a
        reorganization within

        the meaning of Section 368(b) of the Code (Revenue Ruling 72-206, 1972-1
        C.B. 104).

   (2)  Interim Bank A's basis of the assets received from the Mutual Holding
        Company will equal the basis of such assets in the hands of Mutual
        Holding Company immediately before the conversion (Section 362(b) of the
        Code).

   (3)  Interim Bank A's holding period of the assets received from Mutual
        Holding Company include the period during which Mutual Holding Company
        held such assets prior to the Conversion (Section 1223(2) of the Code).

   (4)  Owners of mutual interests in Mutual Holding Company will recognize no
        gain or loss on their constructive exchange of their mutual interests
        for liquidation accounts in Interim Bank A (Rev. Rul. 69-3 and Rev. Rul.
        69-646).

   (5)  The part of the taxable year of Mutual Holding Company before the
        conversion and the part of the taxable year of Interim Bank A after the
        conversion will constitute a single taxable year of Interim Bank A. (See
        Revenue Ruling 57-276, 1957-1 C.B. 126). Consequently, the Mutual
        Holding Company will not be required to file a federal income tax return
        for any portion of such taxable year (Section 1.381(b)-1(a)(2) of the
        Treasury Regulations).

   (6)  As provided by Section 381(c)(2) of the Code and Section 1.381(c)(2)-1
        of the Treasury Regulations, Interim Bank A will succeed to and take
        into account the earnings and profits or deficit in earnings and profits
        of Mutual Holding Company.

   (7)  For purposes of Section 381 of the Code, the Interim Bank A will be
        treated the same as the Mutual Holding Company would have been had there
        been no reorganization. Accordingly, the taxable year of the Mutual
        Holding Company will not end on the effective date of the proposed
        transaction merely because of the transfer of assets of the Mutual
        Holding Company to the Interim Bank A and the tax attributes of Mutual
        Holding Company enumerated in Section 381(c) will be taken into account
        by Interim Bank A as if there had been no reorganization (Section
        1.381(b)-1(a)(2)) of the Treasury Regulations).

Downstream merger of Interim Bank A into Bank and Holding Company formation
- ---------------------------------------------------------------------------

   (1)  Merger 1 should qualify as a reorganization within the meaning of
        Section 368(a)(1)(A) of the Code. Therefore, both Interim Bank A and the
        Bank will be a party to a "reorganization" as defined in Section 368(b)
        of the Code.

   (2)  Interim Bank A will recognize no gain or loss pursuant to Merger 1.

   (3)  Bank will recognize no gain or loss  upon the receipt of the assets of
        Interim Bank A in Merger 1.

   (4)  Merger 2 will qualify as a reorganization within the meaning of Section
        368(a)(1)(A) of the Code.  Pursuant to Section 368(a)(2)(E) of the Code,
        Merger 2 is not disqualified from qualifying as a reorganization within
        the meaning of Section 368(a)(1)(A) because Holding Company Stock will
        be conveyed to the Bank's public stockholders in exchange for their Bank
        Stock. Therefore, the Bank, the Holding Company, and Interim Bank B will
        each be a party to a reorganization as defined in Section 368(b) of the
        Code.

   (5)  Interim Bank B will recognize no gain or loss  upon the transfer of its
        assets to the Bank pursuant to Merger 2.
 
   (6)  Bank will recognize no gain or loss upon the receipt of the assets of
        Interim Bank B.
 
   (7)  Holding Company will recognize no gain or loss upon the receipt of Bank
        Stock solely in exchange for Holding Company Stock.
 
   (8)  Bank's public shareholders will recognize no  gain or loss  upon their
        receipt of Holding Company Stock solely in exchange for their shares of
        Bank Stock.
 
   (9)  A Bank public shareholder's basis of the Holding Company Stock received
        in exchange for its Bank stock will equal the basis of the Bank stock

        surrendered in exchange therefor, before giving effect to any payment of
        cash in lieu of fraction shares.
 
   (10) A Bank public shareholder's holding period of the Holding Company Stock
        received in exchange for its Bank stock will include the Holding period
        of the Bank Stock, provided that the Bank Stock was held as a capital
        asset on the date of the exchange.
        
   (11) Holding Company will recognize no gain or loss upon the sale of Holding
        Company Stock to investors.
 
   (12) The Eligible Account Holders, Supplemental Eligible Account Holders, and
        Other Members (as such terms are defined in the Plan of Conversion) will
        recognize gain, if any, upon the issuance to them of: (i) withdrawable
        savings accounts in the Bank following the Conversion, (ii) Bank
        Liquidation Interest, and (iii) nontransferable subscription rights to
        purchase Holding Company Stock but only to the extent of the value, if
        any, of the subscription rights.
 
   (13) The tax basis to the holders of Holding Company Stock purchased in the
        public stock offerings will be the amount paid therefor, and the holding
        period for such shares will begin on the date of consummation of such
        offerings if purchased through the exercise of subscription rights.
