                  Re:      Merger of Miners Bank of Lykens with
                           Mid Penn Bank, a Subsidiary of
                           Mid Penn Bancorp, Inc.

Dear Members of the Boards:

     You have  asked  for our  opinion  regarding  certain  federal  income  tax
consequences  of the merger of Miners Bank of Lykens (the  "Bank") with and into
Mid Penn Bank (the "Surviving  Bank") pursuant to which the  shareholders of the
Bank will receive voting common stock of the Surviving  Bank's parent,  Mid Penn
Bancorp, Inc. (the "Holding Company").

     In providing  our  opinions,  we have  reviewed the  Agreement  and Plan of
Reorganization,  dated January 9, 1998, among the Holding Company, the Surviving
Bank and the Bank (the "Plan of  Reorganization")  and the Agreement and Plan of
Merger,  dated January 9, 1998,  by and between the Bank and the Surviving  Bank
(the  "Agreement of Merger").  In rendering our opinions,  we have assumed that:
(a) all parties have the legal  right,  power,  capacity and  authority to enter
into and  perform  all  obligations  under  the Plan of  Reorganization  and the
Agreement  of  Merger;  (b) the due and proper  execution  and  delivery  of all
relevant or necessary instruments and documents;  (c) the receipt of all federal
and state regulatory  approvals  necessary to consummate the merger transaction;
and (d) the satisfaction or proper waiver of any other conditions under the Plan
of Reorganization and the Agreement of Merger so that the merger transaction may
be consummated.  All statements in this letter  regarding the federal income tax
consequences of this merger transaction are based upon the Internal Revenue Code
of 1986, as amended (the "Code"),  the Treasury  Regulations  promulgated by the
United States Department of Treasury (the  "Regulations"),  current positions of
the Internal Revenue Service (the "IRS") as

contained  in  published  Revenue  Rulings  and  Procedures,  current  published
administrative  positions of the IRS, and existing  court  decisions,  all as in
effect as of this date and each of which is subject to change at any time.

     Our opinions are based upon and assume the following Factual Background and
Assumptions relating to the merger transaction:

I.   Factual Background

     A.   The Bank is a Pennsylvania  chartered  commercial  bank. The Bank is a
          full-service  commercial  bank, and commenced  operations on March 20,
          1872,  Its principal  place of business is located at 550 Main Street,
          Lykens, Dauphin County, Pennsylvania.  The Bank is authorized to issue
          15,000 shares of common stock,  par value $5.00 per share, of which on
          June 11, 1998,  14,825 shares were issued and  outstanding  (the "Bank
          Common Stock"). The Bank has approximately 291 shareholders.  The Bank
          Common Stock is not  publicly  traded in any  established  market and,
          therefore, no price quotes are readily available.  The common stock is
          the only class of security,  authorized or  outstanding,  of the Bank.
          Recent sales of the Bank Common  Stock have  occurred  solely  between
          individuals  in limited over the counter  transactions  and in direct,
          privately negotiated  transactions.  The most recent sale prior to the
          public  announcement  of the merger on  January  9, 1998,  as to which
          management  of the Bank is  aware  of the  sales  price,  occurred  on
          December  11, 1997 at a price of One Hundred  Sixty- Five  Dollars and
          Twenty-five  Cents  ($165.25)  per share and  involved  a total of 422
          shares.

     B.   The Surviving Bank is a  Pennsylvania  chartered  banking  institution
          which was acquired by the Holding Company on December 31, 1991. On the
          Effective Date of the merger, the shares of the Bank Common Stock then
          outstanding  and eligible for conversion will be converted into shares
          of  the  Holding  Company's  common  stock  pursuant  to the  Plan  of
          Reorganization.

     C.   The Holding Company is a business corporation  organized on August 14,
          1991, under the laws of the Commonwealth of Pennsylvania.  The Holding
          Company is solely  organized to engage in the business and  activities
          associated  with  bank  holding  company's.  The  Holding  Company  is
          authorized to issue 10,000,000 shares of common stock, par value $1.00
          per share,  of which on April 28, 1998,  2,607,552  shares were issued
          and outstanding  (the "Holding  Company Common Stock").  Each share of
          the Bank Common Stock, then issued and outstanding will

          automatically  be  converted  into and become the right to receive ten
          (10)  shares  of  Holding   Company  Common  Stock.   Subject  to  the
          anti-dilutive   provision   of   Section   2.1(b),   of  the  Plan  of
          Reorganization,  the aggregate number of shares of the Holding Company
          to be issued in exchange of Bank Common Stock shall not exceed 148,250
          shares.

     D.   In accordance with the  Pennsylvania  Banking Code of 1965, as amended
          ("Banking  Code"),  the Bank will  merge  with and into the  Surviving
          Bank.  Upon  the  effective  date  of the  merger:  (a)  the  separate
          corporate existence of the Bank will terminate; (b) the Surviving Bank
          will  acquire all of the assets and assume all of the  liabilities  of
          the Bank;  and (c) the  Surviving  Bank will  continue to carry on the
          banking  business  previously  carried  on by the  Bank  at  the  same
          principal  offices.  The  approval  of  shareholders  owning  at least
          two-thirds of the outstanding stock of both the Bank and the Surviving
          Bank are required by law to approve the merger.

     E.   The  shareholders  of the Bank will be  entitled  to receive  ten (10)
          shares of  Holding  Company  Common  Stock for each  share of the Bank
          Common  Stock held by the  shareholder  on the  effective  date of the
          merger.

     F.   Dissenters  to the merger  transaction,  if any, will receive cash for
          their  shares  provided by the Bank,  pursuant to the Banking Code and
          Subchapter D of Chapter 15 of the  Pennsylvania  Business  Corporation
          Law of 1988, as amended (15 C.S. ss.1571, et seq.).

II.  Assumptions

         A.       The Bank proposes to merge with and into the Surviving Bank in
                  order to:  (1) allow the Bank to  acquire  access to  enhanced
                  management  support systems and specialized  banking  services
                  thereby expanding  services to their customers,  and (2) allow
                  the Holding Company, through the Surviving Bank, to expand its
                  market area and give it the  ability,  through  the  Surviving
                  Bank,   to  offer  its   products   and  services  in  Lykens,
                  Pennsylvania.

         B.       The fair market value of the Holding  Company Common Stock and
                  other  consideration  received by each shareholder of the Bank
                  will be  approximately  equal to the fair market  value of the
                  Bank Common Stock surrendered in exchange.

          C.   There is no plan or intention by the shareholders of Bank who own
               one  percent  (1%) or more of the Bank Common  Stock,  and to the
               best of the knowledge of the management of Bank, there is no plan
               or intention on the part of the remaining shareholders of Bank to
               sell,  exchange  or  otherwise  dispose  of a number of shares of
               Holding  Company  Common Stock received in the  transaction  that
               would reduce the Bank shareholders'  ownership of Holding Company
               Common Stock to a number of shares having a value, as of the date
               of the transaction, of less than fifty percent (50%) of the value
               of all of the  formerly  outstanding  Bank Common Stock as of the
               same date. For purposes of this assumption, shares of Bank Common
               Stock  exchanged  for  cash or  other  property,  surrendered  by
               dissenters or exchanged for cash in lieu of fractional  shares of
               Holding  Company  Common  Stock,  are  and  will  be  treated  as
               outstanding Bank Common Stock on the date of the transaction, and
               shares of Bank Common Stock and shares of Holding  Company Common
               Stock held by the Bank shareholders and otherwise sold, redeemed,
               or disposed of prior or subsequent to the merger transaction will
               be considered.

          D.   The Surviving  Bank will acquire at least ninety percent (90%) of
               the fair  market  value of the net  assets  and at least  seventy
               percent  (70%) of the fair market  value of the gross assets held
               by the Bank immediately prior to the merger transaction.  For the
               purposes  of  this  assumption,  amounts  paid  by  the  Bank  to
               dissenters,  amounts paid by the Bank to shareholders who receive
               cash  or  other  property,  assets  of the  Bank  used to pay its
               reorganization  expenses,  and all redemptions and  distributions
               (except  for  regular,   normal   dividends)  made  by  the  Bank
               immediately  preceding the transfer,  are and will be included as
               assets  of  the  Bank  held  immediately   prior  to  the  merger
               transaction.

          E.   Prior to the merger  transaction,  the Holding Company will be in
               control of the Surviving  Bank within the meaning of Code Section
               368(c)(1).

          F.   Following  the  transaction,  the  Surviving  Bank will not issue
               additional  shares of its stock that would  result in the Holding
               Company  losing  control of the Surviving Bank within the meaning
               of Code Section 368(c)(1).

          G.   The  Holding  Company  has no  plan or  intention  to  redeem  or
               otherwise  reacquire  any of its stock to be issued in the merger
               transaction.

          H.   The Holding  Company has no plan or intention  to  liquidate  the
               Surviving Bank; to merge the Surviving Bank with and into another
               corporation, other than the

               Bank as hereinabove  described;  to sell or otherwise  dispose of
               the stock of the Surviving  Bank; or to cause the Surviving  Bank
               to sell or otherwise  dispose of any of the assets of the Bank to
               be acquired in the merger  transaction,  except for  dispositions
               made in the ordinary course of business,  and transfers described
               in Code Section 368(a)(2)(C).

          I.   The  liabilities  of the Bank to be assumed by the Surviving Bank
               and the liabilities to which the  transferred  assets of the Bank
               are subject were  incurred by the Bank in the ordinary  course of
               its  business,   and  are  associated   with  the  assets  to  be
               transferred.

          J.   Following  the  merger  transaction,   the  Surviving  Bank  will
               continue the historic  business of the Bank or use a  significant
               portion of the Bank's business assets in a business.

          K.   The  Holding  Company,  the  Bank,  the  Surviving  Bank  and the
               shareholders of the Bank will pay their respective  expenses,  if
               any, incurred in connection with the merger transaction.

          L.   There is no  intercorporate  indebtedness  existing  between  the
               Holding  Company and the Bank or between the  Surviving  Bank and
               the Bank that was  issued or  acquired,  or will be  settled at a
               discount.

          M.   No two parties to the merger transaction are investment companies
               as defined in Code Sections 368(a)(2)(F)(iii) and (iv).

          N.   The Bank is not under the  jurisdiction  of a court in a Title 11
               or similar case within the meaning of Code Section 368(a)(3)(A).

          O.   The adjusted  basis and fair market value of the Bank's assets to
               be  transferred  to the Surviving  Bank will,  in each  instance,
               equal or exceed the sum of the Bank's  liabilities  to be assumed
               by the Surviving Bank, plus the liabilities, if any, to which the
               transferred assets are subject.

          P.   No stock  of the  Surviving  Bank  will be  issued  to any of the
               shareholders of the Bank in the merger transaction.

          Q.   There is no larger  integrated  transaction  of which the  merger
               transaction constitutes only one step.

          R.   The expenses of the merger  transaction and the amount to be paid
               to  dissenters,  if any, will not exceed ten percent (10%) of the
               fair market value of the net assets of the Bank.

          S.   Within the past three (3) years, there were no redemptions of the
               Bank  Common  Stock  made in  contemplation  of this or any other
               merger transaction.

          T.   There  are  no  fractional   shares  of  the  Bank  Common  Stock
               outstanding and no fractional shares will be issued in the merger
               transaction.

          U.   The  Surviving  Bank has no plan or intention of disposing of the
               assets  of  the  Bank  to  be   received  by  it  in  the  merger
               transaction, other than in the ordinary course of business.

          V.   No  dividends  or  distributions  have  been or will be made with
               respect to any of the Bank Common Stock  immediately prior to the
               merger transaction.

          W.   None of the compensation received by any shareholder-employees of
               the Bank will be separate consideration for, or allocable to, any
               of their shares of the Bank Common  Stock;  none of the shares of
               the   Holding    Company    Common   Stock    received   by   any
               shareholder-employees  will be  separate  consideration  for,  or
               allocable to, any employment agreement; and the compensation paid
               to  any  shareholder-employees  will  be  for  services  actually
               rendered  and will be  commensurate  with  amounts  paid to third
               parties bargaining at arm's-length for similar services.

          X.   There  is no  present  plan  or  intention  to  issue  any of the
               authorized  common stock of the Holding  Company in excess of the
               amounts described in this letter in the merger transaction.

          Y.   Prior to the effective  date of the merger  transaction,  neither
               the Holding  Company nor the Surviving Bank held either  directly
               or indirectly any stock or securities in the Bank.

          Z.   The payment of cash in lieu of  fractional  shares of the Holding
               Company  Common  Stock is solely for the purpose of avoiding  the
               expense  and  inconvenience  to the  Holding  Company  of issuing
               fractional shares and does not represent separately bargained-for
               consideration.  The total cash consideration that will be paid in
               the proposed  transaction to the shareholders of the Bank instead
               of





Board of Directors of
MID PENN BANCORP, INC. and

Page 7

               issuing  fractional  shares of the Holding  Company  Common Stock
               will not exceed one percent (1%) of the total  consideration that
               will be issued in the proposed transaction to the Shareholders of
               the Bank in exchange for their shares of Bank Common Stock.  Each
               shareholder  of the Bank will be aggregated  with no  shareholder
               receiving  cash in an  amount  greater  than the value of one (1)
               share of the Holding Company Common Stock.

     Based on the  foregoing  and subject to and  specifically  relying upon the
aforesaid  Factual  Background and Assumptions and other matters herein referred
to, it is our opinion that:

          1.   Provided the merger of the Bank with and into the Surviving  Bank
               qualifies  as a merger  under the  applicable  federal  and state
               laws, the acquisition by the Surviving Bank of substantially  all
               of the assets of the Bank in  exchange  for the  Holding  Company
               Common Stock and the  assumption by the Surviving  Bank of all of
               the  liabilities  of the  Bank  plus  liabilities  to  which  the
               acquired  assets of the Bank may be  subject,  will  qualify as a
               reorganization  within the meaning of Code Sections  368(a)(1)(A)
               and (a)(2)(D). For purposes of this opinion,  "substantially all"
               means at least ninety  percent  (90%) of the fair market value of
               the net assets  and at least  seventy  percent  (70%) of the fair
               market  value  of the  gross  assets  of the  Bank.  The  Holding
               Company,  the Surviving  Bank, and the Bank will each be "a party
               to a reorganization" within the meaning of Code Section 368(b).

          2.   No gain or loss will be recognized to either the Holding Company,
               the Surviving  Bank or the Bank on the transfer of  substantially
               all of Bank's  assets to the  Surviving  Bank in exchange for the
               Holding  Company Common Stock and the assumption by the Surviving
               Bank of all of the  liabilities of the Bank plus the  liabilities
               to which the acquired assets of the Bank may be subject.

          3.   No gain or loss will be  recognized  to the  shareholders  of the
               Bank upon the  exchange of their Bank Common Stock solely for the
               Holding   Company   Common   Stock   pursuant   to  the  Plan  of
               Reorganization and Agreement of Merger, except in respect of cash
               which is received in lieu of the issuance of fractional shares of
               the Holding  Company Common Stock and for any  shareholder of the
               Bank who receives payment in cash as a dissenting shareholder.

          4.   In the case of cash  received by any  shareholder  of the Bank in
               lieu of the  issuance of a  fractional  share of Holding  Company
               Common  Stock,  taxable gain or loss will be  recognized  by such
               shareholder  to the extent of the  difference  between the amount
               the cash  received and the adjusted tax basis of such  fractional
               share interest.

          5.   In the case of cash received by any  shareholder  of the Bank who
               exercises  dissenter's  rights,  taxable  gain  or  loss  will be
               recognized by such  shareholder  to the extent of the  difference
               between  the amount of the cash  received  and the  adjusted  tax
               basis of the shares as to which dissenter's rights are exercised,
               provided  that  the  purchase  is a  complete  redemption  of the
               shareholder's stock ownership interest in the Bank.

          6.   The basis of the shares of the Holding Company Common Stock to be
               received by the  shareholders of the Bank will be the same as the
               basis of the shares of Bank Common Stock exchanged therefor.

          7.   The holding  period of the shares of the Holding  Company  Common
