Ladies and Gentlemen:

         You have requested this firm's opinion regarding certain federal income
tax  consequences  which will result  from the  conversion  of Peoples  Bancorp,
M.H.C., from the two-tier holding company structure to the stock holding company
form, as effectuated  pursuant to the three  integrated  transactions  described
below.  This  Opinion  Letter is  governed  by,  and  should be  interpreted  in
accordance  with,  the Legal Opinion  Accord (the  "Accord") of the American Bar
Association Section of Business Law (1991). As a consequence, it is subject to a
number of qualifications,  exceptions, definitions,  limitations on coverage and
other limitations, all as more particularly described in the Accord. Our opinion
is based upon the existing  provisions of the Internal  Revenue Code of 1986, as
amended (the "Code) and regulations thereunder (the "Treasury Regulations"), and
upon current  Internal  Revenue Service ("IRS")  published  rulings and existing
court decisions, any of which could be changed at any time. Any such changes may
be  retroactive  and could  significantly  modify the  statements  and  opinions
expressed  herein.  Similarly,  any change in the facts and  assumptions  stated
below,  upon which this  opinion is based,  could modify the  conclusions.  This
opinion is as of the date hereof,  and we disclaim any  obligation to advise you
of any change in any matter considered herein after the date hereof.

         We, of course, opine only as to the matters we expressly set forth, and
no  opinions  should  be  inferred  as to any  other  matters  or as to the  tax
treatment of the transactions that we do not specifically address. We express no
opinion as to other federal laws and regulations,  or as to laws and regulations
of other  jurisdictions,  or as to  factual or legal  matters  other than as set
forth herein.

         We have made such other  investigations  as we have deemed  relevant or
necessary for the purpose of this opinion.  In our examination,  we have assumed
the authenticity of original

documents,  the accuracy of copies and the  genuineness of  signatures.  We have
further  assumed the absence of adverse  facts not apparent from the face of the
instruments  and  documents we examined and have relied upon the accuracy of the
factual  matters set forth in the Plan of  Conversion  and  Reorganization  (the
"Plan") and the  Registration  Statement  filed by Peoples  Bancorp,  Inc.  (the
"Company")  with the  Securities  and  Exchange  Commission  ("SEC")  under  the
Securities Act of 1933, as amended,  and the  Application for Conversion on Form
AC filed with the office of thrift Supervision (the "OTS").

         We specifically  express no opinion  concerning tax matters relating to
the Plan under state and local tax laws and under Federal income tax laws except
on the basis of the documents and assumptions  described  above. We note that in
December 1994, the IRS published  Revenue  Procedure 94-76 which states that the
IRS will not issue private letter rulings with respect to a transaction in which
one corporation owns stock in a second corporation, the first corporation is not
the 80 percent  distributee of the second  corporation and the two  corporations
are merged.  The IRS has assumed this  "no-rule"  position to study whether such
downstream mergers circumvent the purpose behind the repeal of General Utilities
& Operating Co. v. Helvering,  296 U.S. 200 (1935).  If the IRS were to conclude
that such  mergers  circumvent  the repeal of General  Utilities,  the IRS could
issue  regulations  which  could  have  the  effect  of  taxing  to the  merging
corporation,  as of the effective  time of the merger,  the fair market value of
the assets of such corporation over its basis in such assets.  Accordingly,  the
issuance of such regulations could  significantly  modify the opinions expressed
herein.

         For purposes of this  opinion,  we are relying on the opinion of FinPro
the  appraiser  of the  Company,  to the  effect  that the  subscription  rights
distributed  to Eligible  Account  Holders  and  Supplemental  Eligible  Account
Holders have no value; and on the  representations  provided to us by the Mutual
Holding  Company and the Bank as described in the  Affidavit of the President of
the Mutual Holding Company and the Bank, incorporated herein by reference.

The Proposed Transactions

         Based solely upon our review of the documents  described  above, and in
reliance  upon such  documents,  we  understand  that the relevant  facts are as
follows.  On August 3, 1995,  Trenton  Savings  Bank  ("Trenton"),  a  federally
chartered mutual savings bank,  reorganized into the mutual holding company form
of  organization.  To accomplish this  transaction,  Trenton  organized  Trenton
Savings Bank,  F.S.B.  (the "Bank") as a wholly-owned  subsidiary.  Trenton then
transferred  virtually all of its assets and liabilities to the Bank in exchange
for __________ shares

of common stock, par value $.10 per share ("Bank Common Stock") of the Bank, and
reorganized   itself  into  "Peoples  Bancorp,   M.H.C."  (the  "Mutual  Holding
Company").

         In  connection  with  the  foregoing   transaction,   the  Bank  raised
approximately  $30 million by selling  ________  shares of Bank Common  Stock at
$10.00  per  share  to the  public  (the  "Minority  Stockholders").  After  the
conclusion of the sale to Minority Stockholders, the Mutual Holding Company held
____% of the Bank's  Common Stock  outstanding.  The shares of Bank Common Stock
that were sold to the Minority Stockholders  constituted  approximately ____% of
the issued and outstanding  shares of the Bank Common Stock. The  reorganization
of Trenton into the mutual holding company form of organization, and the sale to
the  Minority   Stockholders  of  stock  in  the  Bank,  are  sometimes   herein
collectively  referred to as the "MHC Reorganization." On June 23, 1997 the Bank
reorganized into a two-tier holding company form of organization whereby Peoples
Bancorp,  Inc., a  federally-chartered  stock holding company ("Mid-Tier Holding
Company")  became the parent of the Bank and the Mid-Tier Holding Company became
the majority owned subsidiary of the Mutual Holding Company.  To accomplish this
Transaction,  the Bank chartered the Mid-Tier  Holding Company as a wholly owned
subsidiary and the Mid-Tier  Holding  Company  chartered an interim  ("Interim")
federal  stock  savings bank as a wholly owned  subsidiary.  Interim then merged
into the  Bank  with the  Bank's  shareholders,  including  the  Mutual  Holding
Company,  receiving shares of the Mid-Tier Holding Company in exchange for their
shares of Bank Common Stock. The shares of the Mid-Tier Holding Company owned by
the Bank were canceled.

         Following the  reorganization  to the two-tier  holding company form of
organization  on August 27, 1997, the Mutual Holding Company adopted the Plan of
Conversion  and  Reorganization  ("Plan")  providing  for the  conversion of the
Mutual  Holding  Company  into  the  capital  stock  form  of  organization  (as
converted, the "Holding Company").

         At the  present  time,  three  transactions  referred  to as  the  "MHC
Merger",  the "Mid-Tier  Merger",  and the "Bank  Merger" are being  undertaken.
Pursuant  to the Plan,  the  conversion  ("Conversion")  will be effected in the
following steps, each of which will be completed contemporaneously.

          (i)  The Bank will  establish  the  Company as a  first-tier  Delaware
               chartered stock holding company subsidiary.

          (ii) The Company will charter an interim federal association ("Interim
               Savings Bank").

        (iii)  The Mutual Holding  Company will merge with and into the Mid-Tier
               Holding  Company (the "MHC  Merger"),  shares of Mid-Tier  common
               stock  ("Mid-Tier  Common  Stock")  held  by the  Mutual  Holding
               Company will be canceled  and each  Eligible  Account  Holder and
               Supplemental  Eligible Account Holder will receive an interest in
               a liquidation account of the Mid-Tier Holding Company in exchange
               for such person's interest in the Mutual Holding Company.

        (iv)   The  Mid-Tier  Holding  Company will merge with and into the Bank
               (the "Mid-Tier Merger") with the Bank as the resulting entity and
               (i) Minority  Stockholders will constructively  receive shares of
               Bank Common  Stock in exchange  for their Mid- Tier Common  Stock
               and (ii) each Eligible Account Holder and  Supplemental  Eligible
               Account Holder will receive an interest in a liquidation  account
               ("Liquidation Account") of the Bank in exchange for such person's
               interest in the Mid-Tier Holding Company.

        (v)    Contemporaneously  with the Mid-Tier Merger, Interim Savings Bank
               will merge with and into the Bank with the Bank as the  surviving
               entity (the "Bank Merger"). Constructive shareholders of the Bank
               (i.e., Minority Stockholders immediately prior to the Conversion)
               will   exchange  the  shares  of  Bank  Common  Stock  that  they
               constructively received in the Mid-Tier Merger for Company common
               stock  ("Company  Common  Stock")  pursuant to the exchange ratio
               ("Exchange Ratio").


        (vi)   Contemporaneously  with the Bank  Merger,  the Company  will sell
               Company Common Stock in the Offering.

         In the MHC Merger,  a liquidation  account is being  established by the
Mid-tier  Holding  Company  for the  benefit of  Eligible  Account  Holders  and
Supplemental  Account  Holders.   Pursuant  to  Section  19  of  the  Plan,  the
liquidation  account  will be  equal  to the  greater  of (a) the sum of (i) the
percentage of the outstanding shares of the common stock of the Mid-Tier Holding
Company owned by the Mutual Holding Company  multiplied by the Mid-Tier  Holding
Company's  total  stockholders'  equity as reflected in the latest  statement of
financial   condition   contained  in  the  final  Prospectus  utilized  in  the
Conversion,  and (ii) the  restricted  retained  earnings  account that reflects
certain  dividends  waived by the Mutual  Holding  Company;  or (b) the retained
earnings of the Bank at the time the Bank underwent its mutual  holding  company
reorganization.  In the Mid-Tier Merger, the liquidation  account established at
the Mid-Tier Holding Company will be reestablished and will become a part of the
Liquidation Account at the Bank.

         The Plan  complies with the  provisions of Subpart A of 12 C.F.R.  Part
563b, which sets forth the OTS regulations for conversion of mutual institutions
to stock form. The Plan also complies with the  provisions of 12 C.F.R.  Section
575.12(a),  which is the OTS  regulation  governing  the  conversion  of  mutual
holding companies to stock form.

         Upon  the  date of  consummation  of the Bank  Merger  ("the  Effective
Date"),  Interim  Savings Bank will be merged with and into the Bank and Interim
Savings Bank will cease to exist as a legal entity.  All of the then outstanding
shares of Bank Common Stock will be converted  into and become shares of Company
Common  Stock  pursuant  to the  Exchange  Ratio  that  ensures  that  after the
Conversion and before giving effect to Minority  Stockholders'  purchases in the
Offering,  receipt of cash in lieu of  fractional  shares,  and shares for which
dissenters' rights have been exercised,  Minority Stockholders will own the same
aggregate  percentage of the Company's Common Stock as they currently own of the
Bank Common  Stock.  The common  stock of the Interim  Savings Bank owned by the
Company  prior to the Bank Merger will be  converted  into and become  shares of
common stock of the Bank on the Effective Date. The Company Common Stock held by
the Bank  immediately  prior  to the  Effective  Date  will be  canceled  on the
Effective  Date.  Immediately  following the Bank Merger,  additional  shares of
Company Common Stock will be sold to depositors and former  shareholders  of the
Bank and to members of the public in the Offering.

         As a result of the MHC Merger, the Mid-Tier Merger and the Bank Merger,
the Company  will be a publicly  held  corporation,  will  register  the Company
Common Stock under  Section  12(g) of the  Securities  Exchange Act of 1934,  as
amended  (the  "Exchange  Act"),  and  will  become  subject  to the  rules  and
regulations  thereunder and file periodic  reports and proxy statements with the
SEC.  The Bank will  become a wholly  owned  subsidiary  of the Company and will
continue to carry on its business and activities as conducted  immediately prior
to the Conversion.

         The   stockholders   of  the  Company  will  be  the  former   Minority
Stockholders of the Mid-Tier Holding Company immediately prior to the MHC Merger
(i.e., all stockholders of the Bank, excluding the Mutual Holding Company), plus
those  persons who  purchase  shares of Company  Common  Stock in the  Offering.
Nontransferable  rights to  subscribe  for the  Company  Common  Stock have been
granted,  in order  of  priority,  to  depositors  of the Bank who have  account
balances  of $50.00  or more as of the close of  business  on  August  31,  1997
("Eligible Account Holders"), the Bank's tax-qualified employee plans ("Employee
Plans"),  depositors of the Bank who have account  balances of $50.00 or more as
of the close of business on ____________,  199_ ("Supplemental  Eligible Account
Holders"),  other members of the Bank (other than Eligible  Account  Holders and
Supplemental Eligible Account Holders) ("Other Members"), and owners

of shares of Bank Common Stock other than the Mutual Holding Company  ("Minority
Stockholders").  Subscription rights are nontransferable.  The Company will also
offer shares of Company  Common  Stock not  subscribed  for in the  subscription
offering,  if any,  for sale in a community  offering to certain  members of the
general public.

Opinions

         Based on the  foregoing  description  of the MHC Merger,  the  Mid-Tier
Merger and the Bank Merger,  and subject to the  qualifications  and limitations
set forth in this letter, we are of the opinion that:

         1. The MHC Merger  qualifies  as a tax-free  reorganization  within the
meaning of Section 368(a)(1)(A) of the Code. (Section 368(a)(1)(A) of the Code.)

         2. The exchange of the members' equity  interests in the Mutual Holding
Company for  interests  in a  liquidation  account  established  at the Mid-Tier
Holding  Company in the MHC Merger  will  satisfy  the  continuity  of  interest
requirement of Section  1.368-1(b) of the Income Tax Regulations  (cf. Rev. Rul.
69-3, 1969-1 C.B. 103, and Rev. Rul. 69-646, 1969-2 C.B. 54).

         3. The Mutual  Holding  Company will not  recognize any gain or loss on
the  transfer of its assets to the Mid-Tier  Holding  Company in exchange for an
interest in a liquidation  account  established in the Mid-Tier  Holding Company
for the benefit of the Mutual Holding Company's members who remain depositors of
the Bank. (Section 361 of the Code.)

         4. No gain or loss will be recognized by the Mid-Tier  Holding  Company
upon the receipt of the assets of the Mutual  Holding  Company in the MHC Merger
in exchange for the transfer to the members of the Mutual Holding  Company of an
interest in the liquidation  account in the Mid-Tier Holding  Company.  (Section
1032(a) of the Code.)

         5. The basis of the assets of Mutual Holding  Company (other than stock
in the Mid- Tier  Holding  Company) to be received by Mid-Tier  Holding  Company
will be the same as the basis of such assets in the hands of the Mutual  Holding
Company immediately prior to the transfer. (Section 362(b) of the Code.)

         6. The  holding  period of the  assets of the  Mutual  Holding  Company
(other  than stock in  Mid-Tier  Holding  Company)  to be  received  by Mid-Tier
Holding Company will include the

holding  period  of those  assets in the hands of the  Mutual  Holding  Company.
(Section 1223(2) of the Code.)

         7. Mutual Holding  Company  members will recognize no gain or loss upon
the  receipt of an  interest  in the  liquidation  account in  Mid-Tier  Holding
Company for their membership interest in Mutual Holding Company. (Section 354(a)
of the Code.)

         8. The Mid-Tier Merger  qualifies as a tax-free  reorganization  within
the meaning of Section  368(a)(1)(A) of the Code.  (Section  368(a)(1)(A) of the
Code.)

         9. The  exchange of the  interest  in the  Mid-Tier  Holding  Company's
liquidation  account for interests in a Liquidation  Account  established at the
Bank in the Mid-Tier Merger will satisfy the continuity of interest  requirement
of Section  1.368-1(b) of the Income Tax Regulations (cf. Rev. Rul. 69-3, 1969-1
C.B. 103, and Rev. Rul. 69-646, 1969-2 C.B. 54).

         10. The Mid-Tier Holding Company will not recognize any gain or loss on
the  transfer  of its  assets  to the  Bank in  exchange  for an  interest  in a
Liquidation Account established in the Bank for the benefit of those persons who
remain  depositors of the Bank and the Bank's assumption of the Mid-Tier Holding
Company's liabilities, if any. (Section 361 of the Code.)

         11. No gain or loss will be  recognized by the Bank upon the receipt of
the assets of the Mid-Tier  Holding  Company in the Mid-Tier  Merger in exchange
for the transfer to Bank depositors with an interest in the liquidation  account
of the Mid-Tier Holding Company of an interest in the Liquidation Account in the
Bank. (Section 1032(a) of the Code.)

         12. The basis of the assets of the Mid-Tier Holding Company (other than
stock in the Bank) to be  received by Bank will be the same as the basis of such
assets in the hands of the Mid- Tier Holding  Company  immediately  prior to the
transfer. (Section 362(b) of the Code.)

         13. The holding  period of the assets of the Mid-Tier  Holding  Company
(other  than stock in Bank) to be  received  by Bank will  include  the  holding
period of those assets in the hands of the Mid-Tier Holding Company  immediately
prior to the transfer. (Section 1223(2) of the Code.)

         14. Persons who have an interest in the liquidation account established
in the Mid -Tier Holding  Company  (i.e.,  former  members of the Mutual Holding
Company)  will  recognize no gain or loss upon the receipt of an interest in the
Liquidation Account in the Bank and non-transferable

subscription  rights in  exchange  for their  interest in the  Mid-Tier  Holding
Company liquidation account. (Section 354(a) of the Code).

         15. The Mid-Tier  Holding Company  shareholders  will not recognize any
gain or loss upon their constructive exchange of Mid-Tier Holding Company Common
Stock for Bank Common Stock.

         In addition, we are of the opinion that, based on the foregoing:

         16. The Bank Merger qualifies 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.
For these  purposes,  each of the Bank, the Company and Interim Savings Bank are
"a party to the reorganization within the meaning of Section 368(b) of the Code.

         17. Interests in the liquidation  account  established at the Bank, and
the shares of Bank  Common  Stock  held by Mid -Tier  Holding  Company  prior to
consummation  of the Mid-Tier  Merger,  will be  disregarded  for the purpose of
determining that an amount of stock in the Bank which  constitutes  "control" of
such  corporation  was  acquired by the Company in exchange for shares of common
stock of the Company pursuant to the Bank Merger (Code Section 368(c)).

          18. The  exchange of shares of Company  Common Stock for the shares of
the Bank Common Stock in the Bank Merger, following consummation of the Mid-Tier
Merger,  will  satisfy  the  continuity  of interest  requirement  of Income Tax
Regulation Section 1.368-1(b) in the Bank Merger.

         19.  Interim  Savings Bank will not  recognize  any gain or loss on the
transfer  of its  assets  to Bank in  exchange  for Bank  Common  Stock  and the
assumption by Bank of the liabilities, if any, of Interim Savings Bank. (Section
361(a) and 357(a) of the Code.)

         20.  Bank will not  recognize  any gain or loss on the  receipt  of the
assets of Interim  Savings  Bank in  exchange  for Bank Common  Stock.  (Section
1032(a) of the Code.)

         21. Bank's basis in the assets  received  from Interim  Savings Bank in
the proposed  transaction  will,  in each case, be the same as the basis of such
assets  in  the  hands  of  Interim  Savings  Bank  immediately   prior  to  the
transaction. (Section 362(b) of the Code.)

Page 9

         22. Bank's holding period for the assets  received from Interim Savings
Bank in the proposed  transaction  will,  in each  instance,  include the period
during which such assets were held by Interim Savings Bank.  (Section 1223(2) of
the Code.)

         23. The Company will not recognize any gain or loss upon its receipt of
Bank Common Stock in exchange for Interim Savings Bank stock. (Section 354(a) of
the Code.)

         24. Bank  shareholders  will not  recognize any gain or loss upon their
exchange  of Bank  Common  Stock  solely  for shares of  Company  Common  Stock.
(Section 354(a) of the Code.)

         25.  Each  Bank  shareholder's  aggregate  basis in his or her  Company
Common Stock received in the exchange will be the same as the aggregate basis of
the Bank Common Stock surrendered in exchange  therefor.  (Section 358(a) of the
Code.)

         26. Each Bank shareholder's holding period in his or her Company Common
Stock  received in the exchange  will  include the period  during which the Bank
Common  Stock  surrendered  was  held,  provided  that  the  Bank  Common  Stock
surrendered is a capital asset in the hands of the Bank  shareholder on the date
of the exchange. (Section 1223(1) of the Code.)

         27. No gain or loss will be recognized by Eligible  Account Holders and
Supplemental  Eligible Account Holders upon distribution to them of subscription
rights to purchase  shares of Common Stock,  provided that the amount to be paid
for the Common Stock is equal to the fair market value of the Common Stock.

Analysis

         Section  368(a)(1)(A) of the Code defines the term  "reorganization" to
include a "statutory  merger or  consolidation"  of corporations such as the MHC
Merger and the Mid-Tier Merger. Section 368(a)(2)(E) of the Code provides that a
transaction otherwise qualifying as a merger under Section 368(a)(1)(A), such as
the Bank  Merger,  shall not be  disqualified  by reason of the fact that common
stock  of  a  corporation   (referred  to  in  the  Code  as  the   "controlling
corporation")  (i.e., the Company) which before the merger was in control of the
merged corporation is used in the transaction if:

          (i)  after the transaction,  the corporation surviving the merger (the
               Bank)  holds   substantially   all  of  its  properties  and  the
               properties of the merged corporation

               (Interim   Savings   Bank)   (other  than  common  stock  of  the
               controlling   corporation   (the  Company)   distributed  in  the
               transaction); and

          (ii) in  the  transaction,   former   stockholders  of  the  surviving
               corporation (the Bank stockholders)  exchanged,  for an amount of
               voting common stock of the controlling corporation,  an amount of
               common  stock  in the  surviving  corporation  which  constitutes
               control of such corporation.

         Section  1.368-2(b)(1)  of the Treasury  Regulations  provides that, in
order to qualify as a reorganization under Section  368(a)(1)(A),  a transaction
must be a merger or consolidation  effected  pursuant to the corporation laws of
the  United  States  or a state.  The Plan  provides  that the MHC  Merger,  the
Mid-Tier  Merger and the Bank Merger will be  accomplished  in  accordance  with
applicable state and federal law.

         Treasury  Regulations  and case law  require  that,  in addition to the
existence of statutory authority for a merger,  certain other conditions must be
satisfied in order to qualify a proposed transaction as a reorganization  within
the meaning of Section  368(a)(1)(A)  of the Code. The "business  purpose test,"
which requires a proposed merger to have a bona fide business  purpose,  must be
satisfied. See 26 C.F.R. Section 1.368-1(c). We believe that the MHC Merger, the
Mid- tier Merger and the Bank Merger  satisfy the business  purpose test for the
reasons set forth in the Prospectus  under the caption "The  Conversion--Reasons
for the  Conversion."  The "continuity of business  enterprise test" requires an
acquiring  corporation  either to continue an  acquired  corporation's  historic
business or use a significant portion of its historic assets in a business.  See
26 C.F.R. Section 1.368-1(d). We believe that the business conducted by the Bank
prior  to the MHC  Merger,  the  Mid-Tier  Merger  and the Bank  Merger  will be
unaffected by the transactions.

         The  "continuity  of interest  doctrine"  requires that the  continuing
common  stock  interest  of  the  former  owners  of  an  acquired  corporation,
considered  in the  aggregate,  represent a  "substantial  part" of the value of
their  former  interest,  and  provide  them with a  "definite  and  substantial
interest"  in the  affairs of the  acquiring  corporation  or a  corporation  in
control of the acquiring  corporation.  Paulsen v. Comm'r., 469 U.S. 131 (1985);
Helvering  v.  Minnesota  Tea Co.,  296 U.S.  378 (1935);  John A. Nelson Co. v.
Helvering,  296 U.S. 374 (1935);  Southwest Natural Gas Co. v. Comm'r., 189 F.2d
332 (5th Cir. 1951),  cert. denied, 342 U.S. 860 (1951). We believe that the MHC
Merger  satisfies the continuity of interest  doctrine based on the  information
set forth in the Company's  Registration  Statement and based on Revenue Rulings
69- 646, 1969-2 C.B. 54 and 69-3,  1965-1 C.B. 103. We believe that the Mid-Tier
Merger  satisfies the continuity of interest  doctrine based on  representations
received from the Bank in connection

with the preparation of this opinion,  to the effect that, to the best knowledge
of the  management  of  the  Mid-Tier  Holding  Company  and  the  Bank,  former
shareholders of the Mid-Tier  Holding Company  (disregarding  the Mutual Holding
Company) owning 50% or more of all the outstanding stock of the Mid-Tier Holding
Company  immediately prior to the Mid-Tier Merger,  would continue to own shares
of the Bank immediately after the Mid-Tier Merger. We also believe that the Bank
Merger  satisfies the continuity of interest  doctrine based on  representations
received from the Bank in connection with the preparation of this opinion to the
effect  that,  to the best  knowledge  of the  management  of the  Bank,  former
shareholders of the Bank owning 50% or more of all of the  outstanding  stock of
the Bank immediately  prior to the Conversion,  disregarding  shares held by the
Mutual Holding  Company that were canceled in the MHC Merger,  would continue to
own shares of the Company  immediately  after the Bank Merger.  In addition,  we
believe other applicable  requirements of the Treasury  Regulations and case law
which are preconditions to qualification of the MHC Merger,  the Mid-Tier Merger
and the  Bank  Merger  as a  reorganization,  within  the  meaning  of  Sections
368(a)(1)(A)  and  368(a)(2)(E)  of the Code,  are satisfied on the basis of the
information contained in the Plan and the Prospectus.

         As noted above, in December 1994, the IRS published  Revenue  Procedure
94-76  which  states that the IRS will not issue  private  letter  rulings  with
respect  to a  transaction  in  which  one  corporation  owns  stock in a second
corporation,  the first  corporation  is not the 80 percent  distributee  of the
second corporation and the two corporations are merged. The IRS has assumed this
"no-rule"  position to study  whether such  downstream  mergers  circumvent  the
purpose behind the repeal of General Utilities & Operating Co. v. Helvering, 296
U.S. 200 (1935).  Although the IRS has assumed a "no-rule" position to study the
issues associated with such mergers, the IRS has not specifically  rescinded its
prior  position with respect to such mergers,  and  therefore,  at the time that
this transaction is consummated,  the law prior to the publication of Rev. Proc.
94-76,  as reflected in the Code,  Treasury  Regulations,  case law and rulings,
continues  to control the  transaction.  Under such law, we believe that the MHC
Merger  qualifies  as a tax-free  reorganization  within the  meaning of Section
368(a)(1)(A) of the Code. Moreover, there is no indication that the IRS position
will change as the result of its study. If the IRS does change its position with
respect  to the  downstream  merger  of one  corporation  into its less  than 80
percent  owned  distributee,  there is no reason to believe that any such change
will have retroactive effect.

         Section  354 of the  Code  provides  that  no gain  or  loss  shall  be
recognized by stockholders who exchange common stock in a corporation,  which is
a party to a  reorganization,  solely  for common  stock in another  corporation
which is a party to the  reorganization.  Section 356 of the Code  provides that
stockholders  shall recognize gain to the extent they receive money as part of a
reorganization,  such as cash received in lieu of fractional shares. Section 358
of the Code

provides that, with certain  adjustments for money received in a reorganization,
such as cash received in lieu of fractional shares, a stockholder's basis in the
common stock he or she receives in a reorganization shall equal the basis of the
common stock which he or she  surrendered in the  transaction.  Section  1223(1)
states that, where a stockholder  receives property in an exchange which has the
same basis as the property  surrendered,  he or she shall be deemed to have held
the property  received for the same period as the property  exchanged,  provided
that the property exchanged had been held as a capital asset.

         Section  361 of the  Code  provides  that  no gain  or  loss  shall  be
recognized to a corporation which is a party to a reorganization on any transfer
of property pursuant to a plan of reorganization  such as the Plan.  Section 362
of the Code provides that if property is acquired by a corporation in connection
with a  reorganization,  then the basis of such property shall be the same as it
would  be in the  hands of the  transferor  immediately  prior to the  transfer.
Section  1223(2)  of the  Code  states  that  where a  corporation  will  have a
carryover basis in property  received from another  corporation which is a party
to a  reorganization,  the  holding  period  of such  assets in the hands of the
acquiring  corporation  shall include the period for which such assets were held
by the  transferor,  provided that the property  transferred  had been held as a
capital  asset.  Section  1032 of the Code  states that no gain or loss shall be
recognizes  to a  corporation  on the receipt of property in exchange for common
stock.

         We hereby  consent  to the  filing of the  opinion as an exhibit to the
MHC's Application for Approval for Conversion filed with the Commissioner and to
the Company's  Registration Statement on Form S-1 as filed with the SEC. We also
consent  to the  references  to our  firm  in the  Prospectus  contained  in the
Application  for  Approval  of  Conversion  and  S-1  under  the  captions  "The
Conversion-Tax Aspects" and "Legal Opinions."
