MC STOCK OPTION AGREEMENT

                 This MC STOCK OPTION AGREEMENT ("Option
          Agreement") dated as of July 10, 1995, between
          MIDLANTIC CORPORATION ("MC"), a New Jersey corporation
          registered as a bank holding company under the Bank
          Holding Company Act of 1956, as amended ("Bank Holding
          Company Act"), and PNC BANK CORP. ("PNC"), a
          Pennsylvania corporation registered as a bank holding
          company under the Bank Holding Company Act.

                                 WITNESSETH

                 WHEREAS, the Boards of Directors of MC and PNC,
          together with the Board of Directors of PNC Bancorp,
          Inc., have approved an Agreement and Plan of
          Reorganization ("Reorganization Agreement") and have
          adopted a related Agreement and Plan of Merger dated as
          of the date hereof (together referred to herein as the
          "Merger Agreements"), providing for certain
          transactions pursuant to which MC would be merged with
          and into PNC Bancorp, Inc., a subsidiary of PNC;

                 WHEREAS, as a condition to PNC's entry into the
          Merger Agreements and to induce such entry, MC has
          agreed to grant to PNC the option set forth herein to
          purchase authorized but unissued shares of MC Common
          Stock;

                 NOW, THEREFORE, in consideration of the premises
          herein contained, the parties agree as follows:

          1.  Definitions.

                 Capitalized terms defined in the Merger
          Agreements and used herein shall have the same meanings
          as in the Merger Agreements.

          2.  Grant of Option.

                 Subject to the terms and conditions set forth
          herein, MC hereby grants to PNC an option ("Option") to
          purchase up to 10,425,000 shares of MC Common Stock, at
          a price of $48 per share payable in cash as provided in
          Section 4 hereof; provided, however, that in the event
          MC issues or agrees to issue any shares of MC Common
          Stock in breach of its obligations under the Merger
          Agreements at a price less than $48 per share (as
          adjusted pursuant to Section 6 hereof), the exercise
          price shall be equal to such lesser price. 
          Notwithstanding anything else in this Agreement to the
          contrary, the number of shares of MC Common Stock
          subject to the Option shall be reduced to such lesser
          number, if any, as may from time-to-time be necessary,
          but only for so long as may be necessary, to cause PNC
          not to (a) become an interested stockholder for
          purposes of the New Jersey Shareholders Protection Act,
          (b) become an Acquiring Person as such term is defined
          in the MC Rights Agreement or (c) become an "Interested
          Shareholder" or an "Affiliate" or "Associate" thereof
          for purposes of Article EIGHTH of the Restated
          Certificate of Incorporation of MC.

          3.  Exercise of Option.

                      (a)  PNC may exercise the Option, in whole
          or part, at any time or from time to time if a Purchase
          Event (as defined below) shall have occurred and be
          continuing; provided that to the extent the Option
          shall not have been exercised, it shall terminate and
          be of no further force and effect upon the earliest to
          occur of (i) the Effective Date of the Merger or
          (ii) termination of the Merger Agreements in accordance
          with the provisions thereof prior to the occurrence of
          a Purchase Event (other than a termination resulting
          from a willful breach by MC of any covenant contained
          therein) or (iii) six months after termination of the
          Merger Agreements if such termination follows the
          occurrence of a Purchase Event or is due to a willful
          breach by MC of any covenant contained therein; and
          provided further that any such exercise shall be
          subject to compliance with applicable provisions of
          law.

                      (b)  As used herein, a "Purchase Event"
          shall mean any of the following events or transactions
          occurring after the date hereof:

                 (i)    MC or any MC Subsidiary, without having
                        received PNC's prior written consent,
                        shall have entered into an agreement with
                        any person (other than PNC or any PNC
                        Subsidiary) to (x) merge or consolidate,
                        or enter into any similar transaction,
                        with MC or any MC Subsidiary,
                        (y) purchase, lease or otherwise acquire
                        all or substantially all of the assets of
                        MC or any MC Subsidiary or (z) purchase
                        or otherwise acquire (including by way of
                        merger, consolidation, share exchange or
                        any similar transaction) securities
                        representing 20% or more of the voting
                        power of MC or any MC Subsidiary;
                        provided, however, that in no event shall
                        any merger, consolidation, purchase or
                        similar transaction involving only MC and
                        one or more of its Subsidiaries or
                        involving only any two or more of such
                        Subsidiaries, be deemed to be a Purchase
                        Event, provided any such transaction is
                        not entered into in violation of the
                        terms of the Merger Agreements;

                 (ii)   any person (other than MC, any MC
                        Subsidiary, the MC Subsidiaries in a
                        fiduciary capacity, PNC, affiliates of
                        PNC or subsidiaries of PNC in a fiduciary
                        capacity) shall have acquired beneficial
                        ownership or the right to acquire
                        beneficial ownership of 20% or more of
                        the outstanding shares of MC Common Stock
                        (the term "beneficial ownership" for
                        purposes of this Option Agreement having
                        the meaning assigned thereto in
                        Section 13(d) of the Exchange Act and the
                        regulations promulgated thereunder); or

                 (iii)  any person (other than MC, any MC
                        Subsidiary, PNC or any PNC affiliate)
                        (x) shall have made a bona fide proposal
                        to MC by public announcement or written
                        communication that is or becomes the
                        subject of public disclosure to acquire
                        MC or any MC Subsidiary by merger,
                        consolidation, purchase of all or
                        substantially all of its assets or any
                        other similar transaction, (y) shall have
                        commenced a bona fide tender or exchange
                        offer to purchase shares of MC Common
                        Stock such that upon consummation of such
                        offer such person would own or control
                        20% or more of the outstanding shares of
                        MC Common Stock, or (z) shall have filed
                        an application or notice with the Federal
                        Reserve Board or any other federal or
                        state regulatory agency for clearance or
                        approval to engage in any transaction
                        described in clause (i) or (ii) above,
                        and thereafter the holders of MC Common
                        Stock shall have not approved the Merger
                        Agreements and the transactions
                        contemplated thereby at the meeting of
                        such stockholders held for such purpose
                        or such meeting shall not have been held
                        or shall have been cancelled prior to
                        termination of the Merger Agreements.

          If more than one of the transactions giving rise to a
          Purchase Event under this Section 3(b) is undertaken or
          effected, then all such transactions shall give rise
          only to one Purchase Event, which Purchase Event shall
          be deemed continuing for all purposes hereunder until
          all such transactions are abandoned.  As used in this
          Option Agreement, "person" shall have the meanings
          specified in Sections 3(a)(9) and 13(d)(3) of the
          Exchange Act.

                        (c)  In the event PNC wishes to exercise
          the Option, it shall send to MC a written notice (the
          date of which being herein referred to as "Notice
          Date") specifying (i) the total number of shares it
          will purchase pursuant to such exercise, and (ii) a
          place and date not earlier than three business days nor
          later than 60 business days from the Notice Date for
          the closing of such purchase ("Closing Date"); provided
          that if prior notification to or approval of any
          federal or state regulatory agency is required in
          connection with such purchase, PNC shall promptly file
          the required notice or application for approval and
          shall expeditiously process the same and the period of
          time that otherwise would run pursuant to this sentence
          shall run instead from the date on which any required
          notification period has expired or been terminated or
          such approval has been obtained and any requisite
          waiting period shall have passed.

          4.  Payment and Delivery of Certificates.

                        (a)  At the closing referred to in
          Section 3 hereof, PNC shall pay to MC the aggregate
          purchase price for the shares of MC Common Stock
          purchased pursuant to the exercise of the Option in
          immediately available funds by a wire transfer to a
          bank account designated by MC.

                        (b)  At such closing, simultaneously with
          the delivery of cash as provided in subsection (a), MC
          shall deliver to PNC a certificate or certificates
          representing the number of shares of MC Common Stock
          purchased by PNC, and PNC shall deliver to MC a letter
          agreeing that PNC will not offer to sell or otherwise
          dispose of such shares in violation of applicable law
          or the provisions of this Option Agreement.

                        (c)  Certificates for MC Common Stock
          delivered at a closing hereunder may be endorsed with a
          restrictive legend which shall read substantially as
          follows:

                     "The transfer of the shares
                 represented by this certificate is
                 subject to certain provisions of an
                 agreement between the registered
                 holder hereof and Midlantic
                 Corporation and to resale restrictions
                 arising under the Securities Act of
                 1933, as amended, a copy of which
                 agreement is on file at the principal
                 office of Midlantic Corporation.  A
                 copy of such agreement will be
                 provided to the holder hereof without
                 charge upon receipt by Midlantic
                 Corporation of a written request."

          It is understood and agreed that the above legend shall
          be removed by delivery of substitute certificate(s)
          without such legend if PNC shall have delivered to MC a
          copy of a letter from the staff of the Commission, or
          an opinion of counsel, in form and substance
          satisfactory to MC, to the effect that such legend is
          not required for purposes of the Securities Act.

          5.  Representations.

                 MC hereby represents, warrants and covenants to
          PNC as follows:

                      (a)  MC shall at all times maintain
          sufficient authorized but unissued shares of MC Common
          Stock so that the Option may be exercised without
          authorization of additional shares of MC Common Stock. 

                      (b)  The shares to be issued upon due
          exercise, in whole or in part, of the Option, when paid
          for as provided herein, will be duly authorized,
          validly issued, fully paid and nonassessable.

          6.  Adjustment Upon Changes in Capitalization.

                 In the event of any change in MC Common Stock by
          reason of stock dividends, split-ups,
          recapitalizations, combinations, exchanges of shares or
          the like, the type and number of shares subject to the
          Option, and the purchase price per share, as the case
          may be, shall be adjusted appropriately.  In the event
          that any additional shares of MC Common Stock are
          issued or otherwise become outstanding after the date
          of this Option Agreement (other than pursuant to this
          Option Agreement), the number of shares of MC Common
          Stock subject to the Option shall be adjusted so that,
          after such issuance, it equals 19.99% of the number of
          shares of MC Common Stock then issued and outstanding
          without giving effect to any shares subject or issued
          pursuant to the Option.  Nothing contained in this
          Section 6 shall be deemed to authorize MC to breach any
          provision of the Merger Agreements.

          7.  Registration Rights.

                 MC shall, if requested by PNC, as expeditiously
          as possible following the occurrence of a Purchase
          Event and prior to the second anniversary thereof, file
          a registration statement on a form of general use under
          the Securities Act if necessary in order to permit the
          sale or other disposition of the shares of MC Common
          Stock that have been acquired upon exercise of the
          Option in accordance with the intended method of sale
          or other disposition requested by PNC.  PNC shall
          provide all information reasonably requested by MC for
          inclusion in any registration statement to be filed
          hereunder.  MC will use its best efforts to cause such
          registration statement first to become effective and
          then to remain effective for such period not in excess
          of 180 days from the day such registration statement
          first becomes effective as may be reasonably necessary
          to effect such sales or other dispositions.  The
          obligations of MC hereunder to file a registration
          statement and to maintain its effectiveness may be
          suspended for one or more periods of time not exceeding
          60 days in the aggregate if the Board of Directors of
          MC shall have determined that the filing of such
          registration statement or the maintenance of its
          effectiveness would require disclosure of nonpublic
          information that would materially and adversely affect
          MC.  The first registration effected under this
          Section 7 shall be at MC's expense except for
          underwriting commissions and the fees and disbursements
          of PNC's counsel attributable to the registration of
          such MC Common Stock.  A second registration may be
          requested hereunder at PNC's expense.  In no event
          shall MC be required to effect more than two
          registrations hereunder.  The filing of any
          registration statement hereunder may be delayed for
          such period of time as may reasonably be required to
          facilitate any public distribution by MC of MC Common
          Stock.  If requested by PNC, in connection with any
          such registration, MC will become a party to any
          underwriting agreement relating to the sale of such
          shares, but only to the extent of obligating itself in
          respect of representations, warranties, indemnities and
          other agreements customarily included in such
          underwriting agreements.  Upon receiving any request
          from PNC or assignee thereof under this Section 7, MC
          agrees to send a copy thereof to PNC and to any
          assignee thereof known to MC, in each case by promptly
          mailing the same, postage prepaid, to the address of
          record of the persons entitled to receive such copies.

          8.  Severability.

                 If any term, provision, covenant or restriction
          contained in this Option Agreement is held by a court
          or a federal or state regulatory agency of competent
          jurisdiction to be invalid, void or unenforceable, the
          remainder of the terms, provisions and covenants and
          restrictions contained in this Option Agreement shall
          remain in full force and effect, and shall in no way be
          affected, impaired or invalidated.  If for any reason
          such court or regulatory agency determines that the
          Option will not permit the holder to acquire the full
          number of shares of MC Common Stock provided in
          Section 2 hereof (as adjusted pursuant to Section 6
          hereof), it is the express intention of MC to allow the
          holder to acquire or to require MC to repurchase such
          lesser number of shares as may be permissible, without
          any amendment or modification hereof.

          9.  Miscellaneous.

                      (a)  Expenses.  Except as otherwise
          provided herein, each of the parties hereto shall bear
          and pay all costs and expenses incurred by it or on its
          behalf in connection with the transactions contemplated
          hereunder, including fees and expenses of its own
          financial consultants, investment bankers, accountants
          and counsel.

                      (b)  Entire Agreement.  Except as otherwise
          expressly provided herein, this Option Agreement
          contains the entire agreement between the parties with
          respect to the transactions contemplated hereunder and
          supersedes all prior arrangements or understandings
          with respect thereto, written or oral.  Notwithstanding
          anything to the contrary contained in this Agreement or
          the Merger Agreements, this Agreement shall be deemed
          to amend the Confidentiality Agreement so as to permit
          PNC to enter into this Agreement and exercise all of
          its rights hereunder, including its right to acquire MC
          Common Stock upon exercise of the Option.  The terms
          and conditions of this Option Agreement shall inure to
          the benefit of and be binding upon the parties hereto
          and their respective successors and assigns.  Nothing
          in this Option Agreement, expressed or implied, is
          intended to confer upon any party, other than the
          parties hereto, and their respective successors and
          assigns, any rights, remedies, obligations or
          liabilities under or by reason of this Option
          Agreement, except as expressly provided herein.

                      (c)  Assignment.  Neither of the parties
          hereto may assign any of its rights or obligations
          under this Option Agreement or the Option created
          hereunder to any other person, without the express
          written consent of the other party, except that in the
          event a Purchase Event shall have occurred and be
          continuing PNC may assign in whole or in part its
          rights and obligations hereunder; provided, however,
          that until the date 30 days following the date on which
