Gentlemen:

You have  requested the opinion of KPMG Peat  Marwick,  LLP (KPMG) as to certain
federal  income tax  consequences  of a proposed  merger of  Penncore  Financial
Services Inc. into ML Bancorp,  Inc. In preparing this opinion  letter,  we have
relied, in part, upon certain factual descriptions provided in the AGREEMENT AND
PLAN OF MERGER  dated  February  4, 1997  (Agreement)  by and  between  Penncore
Financial  Services,  Inc.  and ML  Bancorp,  Inc.  as  well  as the  facts  and
representations which are provided below under the headings "STATEMENT OF FACTS"
and  "REPRESENTATIONS".  If any fact or  representation  contained herein is not
complete or accurate it is important that we be notified  immediately in writing
as this would cause us to change our opinion.

It is our  understanding  that  this  opinion  is to be  included  in Form  S-4,
Registration  Statement  under the  Securities Act of 1933, to be filed with the
Securities  Exchange  Commission,  and  is  also  to  be  included  in  a  proxy
statement/prospectus  to be furnished  to the  shareholders  of Penncore  Common
Stock. The usage and reference of our above mentioned opinion is limited only to
the  aforementioned  use and is not to be used in  conjunction  with  any  other
purpose without our express permission and consent.

capital  structure of 2,000,000 shares of common stock with a par value of $5.00
per share (Penncore  Common Stock),  of which 398,868 shares of common stock are
issued and outstanding as of March 31, 1997.  Penncore's  stock is not listed or

and loan holding company located in Villanova,  Pa.  Bancorp's stock is publicly

purposes  on the accrual  method of  accounting.  Bancorp is an SEC  registrant.
Bancorp has an authorized capital structure of 30,000,000 shares of common stock
with a par value of $0.01 per share (Bancorp Common Stock),  of which 11,276,544
shares of common stock are issued and outstanding as of March 31, 1997.  Bancorp
also has authorized  5,000,000 shares of preferred stock, no par value, of which
no shares are issued and outstanding.

Bancorp and Penncore  have entered into and  agreement  and plan of merger dated
February  4,  1997  whereby  Penncore  would be  merged  with and into  Bancorp.
Shareholders of Penncore will receive in exchange for their shares cash,  shares
of Bancorp  Common Stock,  or a combination of cash and shares of Bancorp Common
Stock (the  "Merger").  Each share of  Penncore  Common  Stock is expected to be
exchanged for cash of  approximately  $36.56  without  interest,  2.50 shares of
Bancorp Common Stock (the Exchange  Ratio),  or a pro-rata  combination of these
two forms of  consideration  in accordance with certain  election and allocation
procedures contained in the Agreement.  Regardless of the election by Penncore's
shareholders,  no more than 70% and no less than 51% of Penncore's shares can be
exchanged for Bancorp Common Stock. Cash will be issued to Penncore shareholders
in lieu of any fractional shares. As a result of the Merger, Bancorp will be the
surviving  corporation  and will  acquire  all the  assets  and  liabilities  of
Penncore and Penncore will merge out of existence.

As the market value of Bancorp Common Stock may change prior to the consummation
of the merger,  the number of Bancorp  Common Stock  shares to be exchanged  for
each share of  Penncore's  shares would vary from the 2.50 shares  listed above.
Any  adjustment  in the Exchange  Ratio will be determined by the average of the
last reported sales prices of Bancorp common stock,  as reported by NASDAQ,  for
the ten trading days ending on the 11th day before the merger becomes  effective
(the  Average  Price).  If the Average  Price of Bancorp  common  stock  exceeds
$16.75,  the Exchange  Ratio shall be  decreased  from 2.50 to a number equal to
$41.875  (which is $ 16.75 x 2.50)  divided by the Average  Price.  However,  if
there has been any public  announcement  prior to the ten trading days ending on
the 11th day before the merger becomes effective, of the proposed acquisition or
sale of all of Bancorp's common stock or substantially  all of Bancorp's assets,
then the Exchange  Ratio shall remain at 2.50 even if the Average  Price exceeds
$16.75. Penncore's Board of Directors may terminate the Merger in the event that
the Average Price of Bancorp's  common stock is less than $ 12.50 unless Bancorp
elects to increase the Exchange Ratio to a number equal to $31.25 divided by the
Average Price.  Upon exercise of the Bancorp  Exchange Ratio Option,  the Merger
will remain in full force and effect.

The following steps will be used to complete and accomplish the Merger:

(i) On the  effective  date of the  Merger,  Penncore  will  merge with and into
Bancorp,  pursuant  to state law upon the  approval of the Merger by the legally
required majority of stockholders of Penncore (75%) and upon receipt of approval
of the  Office of Thrift  Supervision  (OTS),  the  Pennsylvania  Department  of
Banking, and other regulatory agencies. Bancorp will be the

surviving corporation and shall continue its corporate existence.  At that time,
the  separate  corporate  existence  of  Penncore  will cease and all assets and
property  then owned by  Penncore  will  become  the  property  of  Bancorp  and
concurrently  therewith,  Bancorp will assume all of Penncore's  liabilities and
obligations.

(ii)  Shareholders of Penncore will receive in exchange for their shares cash in
the amount of $36.56 without interest, 2.50 shares of Bancorp Common Stock, or a
combination of cash and shares of Bancorp Common Stock, depending on the outcome
of certain  elections,  as described in the  Agreement.  No more than 70% and no
less than 51% of Penncore's  shares will be exchanged for Bancorp  Common Stock.
Cash will be issued to Penncore shareholders in lieu of any fractional shares.

(iii)  Dissenting  shareholders  of Penncore who object to the merger and comply
with  prescribed  statutory  procedures will receive cash from Penncore equal to
the fair market value of their shares of Penncore.

REPRESENTATIONS

KPMG is relying on the  following  representations  in  rendering  the  opinions
contained herein. It is understood that KPMG has not independently  verified the
accuracy of any of these representations:

     (1)  The  fair  market  value  of  the  Bancorp   Common  Stock  and  other
     consideration  received by each Penncore  shareholder will be approximately
     equal to the fair market of the Penncore  Common Stock  surrendered  in the
     exchange.

     (2) To the best of the knowledge of the management of Bancorp and Penncore,
     there is no plan or  intention  by the  shareholders  of  Penncore to sell,
     exchange,  or  otherwise  dispose of a number of shares of  Bancorp  Common
     Stock  received  in  the   transaction   that  would  reduce  the  Penncore
     shareholders'  ownership  of  Bancorp  Common  Stock to a number  of shares
     having a value, as of the date of the transaction,  of less than 50 percent
     of the value of all of the formerly outstanding stock of Penncore as of the
     same date. For purposes of this  representation,  shares of Penncore Common
     Stock  exchanged  for cash or other  property,  surrendered  by  dissenters
     exchanged  for  cash  or  other  property,  surrendered  by  dissenters  or
     exchanged  for cash in lieu of fractional  shares of Bancorp  Common Stock,
     will  be  treated  as  outstanding  Penncore  stock  on  the  date  of  the
     transaction.  Moreover,  shares of  Penncore  Common  Stock  and  shares of
     Bancorp  Common Stock held by Penncore  shareholders  and  otherwise  sold,
     redeemed,  or disposed of prior or  subsequent to the  transaction  will be
     considered in making this representation.

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

     (4) Bancorp has no plan or intention  to reacquire  any of its stock issued
     in the transaction.

     (5) Bancorp has no plan to sell or  otherwise  dispose of any of the assets
     of Penncore  acquired in the transaction,  except for dispositions  made in
     the  ordinary  course  of  business  or  transfers   described  in  Section
     368(a)(2)(C) of the Internal Revenue Code.

     (6) The  liabilities of Penncore  assumed by Bancorp and the liabilities to
     which the  transferred  assets of  Penncore  are subject  were  incurred by
     Penncore in the ordinary course of its business.

     (7) Following the transaction,  Bancorp will continue the historic business
     of Penncore or use a significant portion of Penncore's business assets in a
     business.

     (8) Bancorp,  Penncore,  and the  shareholders  of Penncore  will pay their
     respective expenses, if any, incurred in connection with the transaction.

     (9) There is no  intercorporate  indebtedness  existing between Bancorp and
     Penncore or between Bancorp and Penncore that was issued, acquired, or will
     be settled at a discount.

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

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

     (12) The fair market value of the assets of Penncore transferred to Bancorp
     will equal or exceed the sum of the  liabilities  assumed by Bancorp,  plus
     the amount of  liabilities,  if any,  to which the  transferred  assets are
     subject.

     (13) No  distributions  have been or will be made with respect to the stock
     of Penncore  immediately  preceding  the  proposed  transaction  except for
     regular normal distributions.

     (14) Bancorp does not currently own, nor has it previously owned, any stock
     of Penncore.

     (15) The  payment of cash in lieu of  fractional  shares of Bancorp  Common
     Stock is solely for the purpose of avoiding  the expense and  inconvenience
     to Bancorp of issuing  fractional shares and does not represent  separately
     bargained-for  consideration.  No Penncore shareholder will receive cash in
     lieu of more than a fractional  share of Bancorp Common Stock and the total
     consideration  that will be cash in lieu of fractional  shares will be less
     than 1% of the total consideration paid pursuant to the Merger.

     (16) None of the compensation to be received by the  shareholders/employees
     of Penncore  will be separate  consideration  for, or allocable  to, any of
     their  shares  of  Penncore  stock,  none of the  shares of  Bancorp  stock
     received by any  shareholder/employees  will be separate consideration for,
     or allocable to any employment  agreement,  and the compensation to be 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.

     (17) Shares of Bancorp Common Stock issued as part of the transaction  will
     have a fair market  value less than 50 percent of the fair market  value of
     all the outstanding shares of Bancorp immediately after the Merger.

     (18) The fair market value of the Bancorp  Common  Stock  shares  issued as
     part of the merger will equal or exceed 50 percent of the fair market value
     of the total consideration paid for the Penncore shares.

OPINION

Based solely on the Agreement and the Statement of Facts and Representations set
forth in this  opinion  letter,  it is the  opinion  of KPMG that the  following
federal income tax consequences will occur as a result of the above transaction:

     (1) Provided  the proposed  merger of Penncore  with and into  Bancorp,  as
     described  in the  Agreement,  qualifies  as a statutory  merger,  then the
     Merger will qualify as a reorganization  under section  368(a)(1)(A) of the
     Code.

     (2) Penncore and Bancorp will each be "a party to a reorganization"  within
     the meaning of section 368(b).

     (3) No gain or loss will be  recognized  to Penncore  upon the  transfer of
     substantially  all of its assets to Bancorp in exchange for Bancorp  stock,
     cash, and Bancorp's assumption of Penncore's  liabilities  (sections 361(a)
     and 357(a)).

     (4) No gain or loss will be recognized by Bancorp upon the  acquisition  by
     Bancorp of  substantially  all of the assets of Penncore  in  exchange  for
     Bancorp  stock,  cash,  and the  assumption  of Penncore's  liabilities  by
     Bancorp (Section 1032(a)).

     (5) The basis of each of the Penncore assets  acquired by Bancorp  pursuant
     to the Merger will be the same in the hands of Bancorp as the basis of such
     asset in the hands of  Penncore  immediately  prior to the Merger  (section
     362(b)).

     (6) The  holding  period of the  assets of  Penncore  received  by  Bancorp
     pursuant to the Merger will in each  instance  include the period for which
     such asset was held by Penncore (section 1223(2)).

     (7)  Penncore  shareholders  will  recognize  no gain or  loss  upon  their
     exchange of Penncore Common Stock solely for shares of Bancorp Common Stock
     (section 354(a)).

     (8) If a Penncore  shareholder  receives both cash and Bancorp Common Stock
     for his  Penncore  Common  Stock,  gain will be  recognized,  but not in an
     amount in excess of the amount of cash received.  (Section 356(a)(1) of the
     Code.) With regard to any  Penncore  shareholder,  if the  exchange has the
     effect of the  distribution of a dividend  (determined with the application
     of section 318),  then the amount of gain  recognized that is not in excess
     of such Penncore  shareholder's ratable share of undistributed earnings and
     profits of Penncore will be treated as a dividend. (Section 356(a)(2)). The
     determination of whether the exchange has the effect of the distribution of
     a dividend will be made on a shareholder by shareholder basis in accordance
     with the principles  enunciated in Commissioner  v. Clark,  109 S. Ct. 1455
     (1989). No loss will be recognized. (Section 356(c)).

     (9) The basis of the Bancorp Common Stock  received  pursuant to the Merger
     by the shareholders of Penncore  (including  fractional shares) will be the
     same as the basis of the Penncore stock  surrendered  in exchange  therefor
     decreased by the amount of cash received by the  shareholder  and increased
     by the amount,  if any,  that was  treated as a dividend  and the amount of
     gain  recognized  to the  shareholder  on the exchange  (not  including any
     portion of such gain that is treated as a dividend.)  Section  358(a)(1) of
     the Code.

     (10) The holding period of the Bancorp  Common Stock  received  pursuant to
     the Merger by Penncore  shareholders  will include the period  during which
     the Penncore Common Stock  surrendered in exchange therefor was held by the
     Penncore shareholders, provided

     that the Penncore Common Stock surrendered was a capital asset in the hands
     of the Penncore shareholders on the date of the exchange (section 1223(1)).

     (11) If a Penncore  shareholder elects and receives solely cash or dissents
     to the transaction and receives solely cash in exchange for Penncore Common
     Stock,  such cash will be treated as having been received as a distribution
     in redemption of the Penncore  Common Stock,  subject to the  provisions of
     section  302 of the  Code.  Where,  as a  result  of such  distribution,  a
     shareholder  owns no Bancorp  stock,  either  directly  or by reason of the
     application of section 318, the redemption  will be a complete  termination
     of interest within the meaning of section 302(b)(3),  and such cash will be
     treated  as a  distribution  in full  payment  in  exchange  for his or her
     Penncore  stock as provided in section  302(a)  provided  Penncore is not a
     collapsible   corporation  within  the  meaning  of  section  341(b).  Such
     shareholders will recognize gain or loss under section 1001 measured by the
     difference  between the amount of cash  received and the adjusted  basis of
     the Penncore stock surrendered. Rev. Rule. 74-515, 1974-2 C.B. 118.

     (12) Cash issued in lieu of  fractional  share  interests of Bancorp  stock
     will be treated as if the fractional  shares of Bancorp stock were actually
     issued to the Penncore  shareholders and then redeemed by Bancorp for cash.
     Rev. Rule. 66-365,  1966-2 CB 116. Such cash will be treated as received in
     full payment in exchange  for the Bancorp  fractional  share under  section
     302(a). Rev. Proc. 77-41, 1977-2 CB 574.

     (13) The taxable  year of Penncore  will end on the  effective  date of the
     merger. Section 381(b)(1) of the Code.

     (14)  Bancorp  will  succeed to and take into account the items of Penncore
     described  in section  381(c) of the Code,  subject to the  provisions  and
     limitations  specified in sections  381,  382, 383, and 384 of the Code and
     the regulations thereunder.

     (15) As provided by section 381(c)(2) of the Code and section 1.381(c)(2)-1
     of the Treasury Regulations,  Bancorp will succeed to and take into account
     the earnings and profits,  or deficit in earnings and profits,  of Penncore
     as of the date of the  transfer.  Any  deficit in  earnings  and profits of
     Penncore will be used only to offset earnings and profits accumulated after
     the date of transfer.
