                                  GUARANTEE OF
                     THE PNC FINANCIAL SERVICES GROUP, INC.


         FOR VALUE RECEIVED, THE PNC FINANCIAL SERVICES GROUP, INC. (formerly

unconditionally guarantees to the holder of the Security upon which this
Guarantee is endorsed the due and punctual payment of the principal and interest

Indenture referred to therein. In case of default by PNC Funding Corp (herein
called the "Company") in the payment of any such principal or interest, the
Guarantor agrees duly and punctually to pay the same.

         The Guarantor hereby agrees that its obligations hereunder shall be
absolute and unconditional, irrespective of, and shall be unaffected by, any
invalidity, irregularity or unenforceability of said Security or said Indenture,
any failure to enforce the provisions of said Security or said Indenture, or any
waiver, modification or indulgence granted to the Company with respect thereto,

circumstances which may otherwise constitute a legal or equitable discharge of a
surety or guarantor. The Guarantor hereby waives diligence, presentment, demand
of payment, filing of claims with a court in the event of a merger or bankruptcy
of the Company, any right to require a proceeding first against the Company,
protest or notice with respect to said Security or the indebtedness evidenced
thereby and all demands whatsoever, and covenants that this Guarantee will not
be discharged except by payment in full of the principal of and premium, if any,
and interest on said Security.

         The obligations of the Guarantor evidenced by this Guarantee, to the
extent and in the manner set forth in said Indenture, shall rank pari passu in
right of payment with each other and with the Guarantor's unsecured obligations
to holders of Senior Guarantor Indebtedness (as defined in said Indenture), and
are senior in right of payment to the Existing Guarantor Subordinated
Indebtedness (as defined in said Indenture), and each holder of Securities, by
the acceptance hereof, agrees to and shall be bound by such provisions of said
Indenture. The obligations of the Guarantor evidenced by this Guarantee shall
also rank pari passu in right of payment with the Guarantor's guarantees of the
Company's 6.95% Notes Due 2002 and 7.00% Notes Due 2004 and the Guarantor's
joint and several obligations with PNC Bancorp, Inc. the 9.20% Subordinated
Notes Due 2001 assumed in connection with the merger of Midlantic Corporation
with PNC Bancorp, Inc. on December 31, 1995.

         The Guarantor shall be subrogated to all rights of the holder of said
Security against the Company in respect of any amounts paid by the Guarantor
pursuant to the provisions of this Guarantee; provided, however, that the
Guarantor shall not be entitled to enforce, or to receive any payments arising
out of or based upon, such right of subrogation until the principal of and
premium, if any, and interest then due on all Securities issued under said
Indenture shall have been paid in full.
