AMENDMENT NO. 1 TO

DONTECH II PARTNERSHIP AGREEMENT

     This Amendment No. 1 (this “Amendment”) to the DonTech II Partnership
Agreement (the “DonTech II Partnership Agreement”) dated as of this 28th day of
January, 2000, by and between R.H. Donnelley Inc. (formerly known as The Reuben
H. Donnelley Corporation), a Delaware Corporation (“Donnelley”), and Ameritech
Publishing of Illinois, Inc., a Delaware Corporation (“API/IL”). Donnelley and
API/IL are hereafter sometimes referred to individually as a “Partner” or
collectively as “Partners.”

PREAMBLE

     On or about August 19, 1997, the Partners restructured their relationship
(the “Restructuring”). In connection therewith they executed, among other
documents, the Second Amended and Restated Am-Don Partnership Agreement (the
“DonTech I Partnership Agreement”), which governs the DonTech I Partnership (the
“DonTech I Partnership”) and the DonTech II Partnership Agreement, which governs
the DonTech II Partnership (the “DonTech II Partnership”). In accordance with
the financial analyses performed as the basis of the Restructuring, it was
determined that API/IL would suffer a short-term cash flow shortfall of
$29,898,338.04 due to the Restructuring (the “Shortfall”). Accordingly, the
Partners agreed, subject to the terms and conditions set forth herein and in the
DonTech I Amendment (as defined below), to amend (i) the DonTech I Partnership
Agreement to provide for the payment by the DonTech I Partnership to API/IL as a
preferential distribution of an amount equal to the Shortfall (the “DonTech I
Amendment”) and (ii) the DonTech II Partnership Agreement to provide for the
payment by the DonTech II Partnership to Donnelley of an amount equal to the
Shortfall as a preferential distribution upon dissolution of the DonTech II
Partnership.

     Subject to the terms and conditions set forth herein and in the DonTech I
Amendment (as defined below), the Partners hereby agree as follows:

     1.     Repayment of Shortfall to Partnership. API/IL absolutely and
unconditionally agrees that it shall pay to the DonTech II Partnership, without
offset, counterclaim or any other deduction whatsoever on account of any claim
against the DonTech II Partnership, Donnelley or any other person or entity, an
amount equal to the Shortfall within five business days of the occurrence of any
event of dissolution under Section 9.2 of the DonTech II Partnership Agreement.
Such payment shall be made by wire transfer of immediately available funds.

     2.     Preferential Distribution. In the event of the occurrence of any
event of dissolution under Section 9.2 of the DonTech II Partnership Agreement,
immediately following payment by API/IL of the Shortfall pursuant to Section 1
of this Amendment, the Partners shall cause the DonTech II Partnership to pay to
Donnelley as a preferential distribution an amount equal to the Shortfall after
the creditors have been paid in accordance with Section 9.4(b)(i) of the DonTech
II Partnership Agreement, but before the balance of the assets of the DonTech II
Partnership are distributed in accordance with Section 9.4(b)(ii) of the DonTech
II Partnership Agreement. Notwithstanding Section 9.2(c) of the DonTech II
Partnership Agreement, in the event that following payment by API/IL of the
Shortfall under Section 1 of this Amendment, assets of the DonTech II
Partnership are insufficient to fully pay creditors in accordance with Section
9.2(b)(i) of the DonTech II Partnership Agreement, then API/IL shall be required
to pay to the DonTech II Partnership the entire amount of any such shortfall.

     3.     Effectiveness of Amendment. This Amendment shall not become
effective until such time as the DonTech I Amendment shall have been duly
authorized, executed and delivered, which is the date hereof.

     4.     Entire Agreement. Except as amended hereby, the DonTech II
Partnership Agreement remains in full force and effect and is hereby ratified
and confirmed in all respects.

     5.     Amendments. No amendment to the DonTech II Partnership Agreement, as
hereby amended, shall be effective unless done in accordance with Section 13.5
of the DonTech II Partnership Agreement.

     6.     Amendment Not To Be Construed Against Either Party. The Partners
acknowledge and agree that each has been represented by legal counsel of its
choice throughout the negotiation and drafting of this Amendment, that each has
participated in the drafting thereof, and that this Amendment shall not be
construed in favor of or against either party solely on the basis of a party’s
drafting or participation in the drafting of any portion of this Amendment.

     7.     Applicable Law. This Amendment and the performance of the Partners
hereunder shall be interpreted, construed, and enforced in accordance with the
laws of the State of Illinois.

     8.     Counterparts. This Amendment may be executed in multiple
counterparts. Each such counterpart shall be an original and all together shall
constitute but one and the same Amendment.

     9.     Headings. The headings of Sections in the Amendment are for
convenience only and are not part of this Amendment.

     IN WITNESS WHEREOF, the Partners have executed this Amendment to the
DonTech II Partnership Agreement on the date and year first above written.
