                                    AGREEMENT

         NOW, THEREFORE, in consideration of the premises and the mutual
representations, warranties, covenants and agreements set forth in this
Agreement and the consummation of the transactions contemplated by the Purchase
Agreement, the Parties agree as follows:

                                    ARTICLE 1

                              TERM AND TERMINATION

         SECTION 1.1 TERM. This Agreement will terminate immediately and without
any further action when the Directory Services License Agreement expires at the
end of the Term, is terminated by or on behalf of SBC Directory Operations in
accordance with its terms or is terminated by or on behalf of Publisher in
accordance with its terms or otherwise; provided, however, that notwithstanding
the foregoing (i) in the event of a termination of the Directory Services
License Agreement pursuant to Section 9.4 or 10.1(a) thereof, this Agreement
shall remain in effect to the extent and for the periods specified in Section
9.4(d) and 10.1(a)(iv) thereof, respectively, and (ii) no termination or
expiration of this Agreement will release SBC from liability for any prior
breaches of any provision of this Agreement.

                                    ARTICLE 2

                           EXCLUSIVITY AND NON-COMPETE

         SECTION 2.1 PRINT DIRECTORIES.

         (a) Exclusivity. Publisher will have the exclusive right to (i) publish
and distribute Print Directories and use the Licensed Marks in the Territory as
contemplated in the Directory Services License Agreement and the other
Commercial Agreements and (ii) solicit and sell Local and National yellow pages
and white pages advertising for inclusion in such Print Directories. As used
with respect to Print Directories, (i) "National" yellow pages and white pages
advertising will have the same meaning as provided for such term under the
current Yellow Pages Integrated Media Association ("YPIMA") minimum standards,
and (ii) "Local" yellow pages and white pages advertising shall mean all such
advertising that does not constitute National (as so defined).

         (b) Non-Compete. Until the termination of this Agreement, neither SBC
nor any of its Subsidiaries will directly or indirectly engage in, manage,
operate or have any profit or other equity interest (other than less than 5% of
a Person) in any Person (other than pursuant to the Directory Services License
Agreement) that engages in the business of (i) producing, publishing or
distributing any Print Directories in the Territory, or (ii) soliciting or
selling Local or National yellow pages or white pages advertising for inclusion
in any Print Directories published or distributed in the Territory; provided,
however, if the RHD Entities cease at any time to publish and distribute any
Print Directory in the Territory, SBC may publish and distribute, or cause to be
published and

                                      -2-
<PAGE>

distributed, such directory to the extent necessary to comply with the Legal and
Regulatory Requirements.

         (c) Permitted Activities. Notwithstanding Sections 2.1(a) and 2.1(b) of
this Agreement, neither RHD's exclusivity rights nor SBC's non-compete
obligations described therein will prohibit (i) any SBC Entity from (A)
producing, publishing or distributing (or selling advertising for inclusion in)
industrial guides (other than the Illinois Industrial Guide) in the Territory so
long as such products do not materially compete with and are not significant
substitutes for Print Directories currently published by Publisher or (B) (1)
managing, operating or having any profit or other equity interest in a Certified
Marketing Representative ("CMR") with respect to the sale of National yellow
pages and white pages advertising or (2) earning and collecting a CMR commission
with respect to the sale of National yellow pages and white pages advertising,
or (ii) the SBC Entities from soliciting or selling Telco-Sold White Pages
Products. The Parties hereby agree to terminate, or cause to be terminated, on
the date hereof the agreements set forth on Exhibit A with respect to street
address directories outside of the Territory sold by DonTech II (and RHD agrees
to transfer, or cause to be transferred, all relevant records for such street
address directories to SBC Directory Operations).

         SECTION 2.2 EXISTING IYP DIRECTORIES.

         (a) Non-Compete. Until the termination of this Agreement, neither SBC
nor any of its Subsidiaries will directly or indirectly engage in, manage,
operate or have any profit or equity interest (other than less than 5% of a
Person) in any Person (other than pursuant to the IYP Reseller Agreement) that
engages in the business of soliciting or selling Local IYP Advertising for
inclusion in Existing IYP Directories. Furthermore, until the termination of
this Agreement, SBC will not license the Licensed Marks or any other mark
relating to any SBC Telco, any Existing IYP Directory or any Future Electronic
Directory for which Publisher is acting as exclusive sales agent in the
Territory, to a third party (or Cingular or any of its Subsidiaries) for use in
connection with soliciting and selling Local IYP Advertising for inclusion in
Existing IYP Directories or, in the case of Cingular or any of its Subsidiaries,
in Future Electronic Directories, except for incidental use ancillary to any
solicitation and sales of Local IYP Advertising by a third party for which SBC
does not receive any incremental monetary consideration.

         (b) Local and National IYP Advertising.

                  (i) "Local IYP Advertising" means, any advertising, which for
         this purpose shall include any unpaid listings, to be included in any
         Existing IYP Directory or Future Electronic Directory which is
         solicited from an advertiser physically located in the Territory (each,
         an "Advertiser"), other than any such advertising which (x) promotes
         (A) services to be rendered substantially outside the Territory or (B)
         products, if such advertising substantially directs potential
         purchasers to one or more business establishments or sales personnel
         physically located outside the Territory and (y) is solicited from an
         Advertiser who at the time of such solicitation has, or has a binding
         contract to place, advertisements in

                                      -3-
<PAGE>

         two or more other IYP or electronic directories, and "National IYP
         Advertising" will mean all such advertising which is solicited from an
         Advertiser that does not constitute Local IYP Advertising; provided,
         however, that for five years from the date of this Agreement (the "Five
         Year Period") any advertising to be included in any Existing IYP
         Directory or Future Electronic Directory which is solicited from an
         Advertiser who at the time of such solicitation (i) had previously
         purchased advertising included in SMARTpages (as defined in the IYP
         Reseller Agreement) shall be deemed to be Local IYP Advertising or (ii)
         (A) has Local white or yellow page advertising in a then current Print
         Directory or a binding contract to place such advertising in the next
         publication of a Print Directory shall be deemed to be Local IYP
         Advertising or (B) has National white or yellow page advertising in a
         then current Print Directory or a binding contract to place such
         advertising in the next publication of a Print Directory shall be
         deemed to be National IYP Advertising; and provided, further, that
         except to the extent otherwise provided in clause (ii) of the foregoing
         proviso, if at any time YPIMA or any successor directory industry
         association officially adopts, or subsequently amends, provisions which
         define or establish distinctions between local and national Directory
         Advertising for inclusion in IYP or other electronic directories
         (excluding Print Directories), then the foregoing definitions of "Local
         IYP Advertising" and "National IYP Advertising" will be replaced with
         such definitions or will be amended to reflect such distinctions, as
         applicable. The date on which such definitions or distinctions first
         become effective is referred to herein as the "New Regulation Date."

                  (ii) Unless the New Regulation Date shall have occurred, a
         reasonable time prior to the end of the Five Year Period, the parties
         to the Directory Services License Agreement will negotiate in good
         faith any revisions to such definitions which they deem appropriate or
         desirable and in so doing will give significant weight to any industry
         standards which may have developed which define or distinguish between
         local and national advertising in the context of Existing IYP
         Directories and/or Future Electronic Directories as they may evolve
         with changing technologies and practices; provided, however, that the
         foregoing shall not obligate either party to agree to any such
         revisions. During the term of the Directory Services License Agreement,
         the parties will negotiate in good faith policies and procedures (which
         must be consistent with the spirit and principles of the definitions in
         Section 2.2(b)(i) above, except that the first proviso to such
         definitions shall not be given effect for any period after the Five
         Year Period) that will be used to determine whether and to what extent
         IYP advertising which promotes services to be performed or products to
         be sold both inside and outside the Territory is Local IYP Advertising
         or National IYP Advertising (as the definitions of such terms may
         change over time).

               SECTION 2.3                  PREFERRED PROVIDER.

         (a) Future Electronic Directories. With respect to any Future
Electronic Directory published by SBC or any of its Controlled Subsidiaries, SBC
will give Publisher

                                      -4-
<PAGE>

the opportunity to negotiate with SBC Directory Operations, for 30 days on a
non-exclusive basis, a mutually acceptable agreement under which Publisher might
become the sales agent of SBC or such Controlled Subsidiary for Local IYP
Advertising for inclusion in such Future Electronic Directory for an agreed upon
term and each party agrees to conduct such negotiations in good faith; provided,
however, that (i) if Publisher makes a binding offer to SBC Directory Operations
during such 30-day period setting forth in reasonable detail the price and all
other material terms and conditions on which it is prepared to agree to perform
such services, then SBC or such Controlled Subsidiary will not enter into any
agreement with a third party to provide such services unless the price and such
other material terms and conditions of such third party agreement are, in the
aggregate and in SBC Directory Operations' reasonable judgment, more favorable
to SBC or such Controlled Subsidiary than those offered by Publisher to SBC or
such Controlled Subsidiary and (ii) the foregoing will not impose any obligation
on either party to agree to or enter into any such agreement. Neither SBC nor
any of its Controlled Subsidiaries will enter into any agreement with any third
party to offer or sell any Local IYP Advertising for inclusion in a Future
Electronic Directory which agreement has a term of more than three years and,
within a commercially reasonable period before the expiration of the term of any
such agreement, SBC Directory Operations will initiate a new preferred provider
process prior to renewing, extending or replacing such agreement; provided,
however, that if and when Cingular becomes a Controlled Subsidiary of SBC, the
foregoing shall not apply until the expiration (without giving effect to any
discretionary renewal rights in favor of Cingular) or termination of any then
existing sales agency arrangements of Cingular or any of its Subsidiaries with
respect to the sale of Local IYP Advertising in the Territory for inclusion in a
Future Electronic Directory.

         (b) Print Directories. With respect to any Print Directory published by
Cingular or any of its Subsidiaries when Cingular is a Controlled Subsidiary of
SBC, SBC will give Publisher the opportunity to negotiate with Cingular, for 30
days on a non-exclusive basis, a mutually acceptable agreement under which
Publisher might become Cingular's sales agent for Local yellow pages and white
pages advertising for inclusion in such Print Directory for an agreed upon term
and each party agrees to conduct such negotiations in good faith; provided,
however, that (i) if Publisher makes a binding offer to Cingular during such
30-day period setting forth in reasonable detail the price and all other
material terms and conditions on which it is prepared to agree to perform such
services, then Cingular will not enter into any agreement with a third party to
provide such services to it unless the price and such other material terms and
conditions of such third party agreement are, in the aggregate and in Cingular's
reasonable judgment, more favorable to it than those offered by Publisher to it
and (ii) the foregoing will not impose any obligation on either party to agree
to or enter into any such agreement. At any time when Cingular is a Controlled
Subsidiary of SBC, SBC will not permit Cingular

                                      -5-
<PAGE>

or any of its Subsidiaries to enter into any agreement with any third party to
offer or sell any Local yellow pages or white pages advertising for inclusion in
any Print Directory published by it which agreement has a term of more than
three years and, within a commercially reasonable period before the expiration
of the term of any such agreement, Cingular will initiate a new preferred
provider process prior to renewing, extending or replacing such agreement.
Notwithstanding the foregoing, if any Print Directory published by Cingular or
any of its Subsidiaries at the time when Cingular becomes a Controlled
Subsidiary of SBC is subject to an existing sales agency agreement with respect
to the sale of Local yellow pages or white pages advertising in the Territory
for inclusion in such Print Directory, then this Section 2.3(b) shall not apply
to such Print Directory until the expiration or termination (without giving
effect to any discretionary renewal rights in favor of Cingular or its
Subsidiaries) of such agreement.

         SECTION 2.4 ACQUISITION BY OR OF SBC.

         (a) If SBC acquires a Person whose operations would cause SBC to
violate Sections 2.1 or 2.2 of this Agreement, then SBC will not be deemed to
have breached such Sections as a result of such operations if it in good faith
attempts to divest or cease such operations and in fact divests or ceases such
operations within 12 months of the closing of such acquisition.

         (b) If SBC is acquired by a Person that is engaged in operations that
cause SBC to violate Sections 2.1 or 2.2 of this Agreement, then SBC will not be
deemed to have breached such Sections as a result of such operations of the
acquiring party that exist as of the closing of such sale so long as the
acquiring party agrees in writing that (i) Publisher will continue to have the
exclusive right to produce, publish and distribute (and solicit or sell
advertising for) Print Directories in the Territory and use the ILEC brand as
contemplated in the Directory Services License Agreement and the other
Commercial Agreements, and (ii) it and its Controlled Affiliates will agree to
abide by the restrictions set forth under Sections 2.1(b), 2.2 and 2.3 and
Article 3 of this Agreement; provided, however, in the event that the acquiring
party substitutes a New ILEC Brand for the existing ILEC brand in the Territory,
Publisher will have the exclusive right and obligation to use the New ILEC Brand
for the publishing of Print Directories and the acquiring party must shut down
any of its existing Print Directories or rebrand them so that such directories
do not use the New ILEC Brand, the Licensed Marks or any brand or mark which
purchaser previously used on any print directory distributed in the Territory or
on any Existing IYP Directory or Future Electronic Directory for which acquiring
party sold Local IYP Advertising in the Territory.

         SECTION 2.5 RESERVATIONS.

         (a) No Rights to Electronic Directory Platforms. Subject to the IYP
Reseller Agreement, nothing in this Agreement will give either Party any right
to place advertising or, except as expressly provided in Section 2.3 of this
Agreement, otherwise participate in any existing or future electronic directory
platform or service owned or used by the other Party.

         (b) Cingular. None of the obligations set forth in Section 2.1 or 2.2
of this Agreement will apply to Cingular or any of its Subsidiaries; provided,
however, that, Section 2.1(b) shall apply to Cingular and its Subsidiaries from
and after the time (if any) that Cingular becomes a wholly owned Subsidiary of
SBC (the "Wholly Owned Date") and; provided, further, that neither Cingular nor
any of its Subsidiaries will be deemed to

                                      -6-
<PAGE>

be in violation of Section 2.1(b) of this Agreement as a result of any
activities that any of them conducts as of the Wholly Owned Date and they may
continue to conduct such activities without violating 2.1(b) of this Agreement,
in each case as long as such activities were commenced for a valid business
purpose and not primarily for the purpose of circumventing the restrictions in
this Section 2.5(b) and Section 2.1(b) of this Agreement. Notwithstanding this
Section 2.5(b), (i) if any Subsidiary or business of SBC that is subject to the
restrictions in Sections 2.1 and 2.2 of this Agreement is sold or otherwise
transferred to Cingular or any of its Subsidiaries, such Subsidiary or business
(but not any other Subsidiary or business of Cingular) will remain subject to
such restrictions as long as they apply to SBC, and (ii) if Cingular or any of
its Subsidiaries merges into, consolidates with or otherwise transfers all or
any portion of its assets or its Subsidiaries' assets to any SBC Entity that is
subject to the restrictions in Sections 2.1 and 2.2 of this Agreement, the
obligations of such SBC Entity under this Agreement shall not be affected by
such transaction.

                                    ARTICLE 3

                                NON-SOLICITATION

         SECTION 3.1 NON-SOLICITATION. During (a) the period between the date of
this Agreement and the second anniversary (or, in the case of senior sales and
executive management, the third anniversary) of the date of this Agreement and
(b) the two year period (or, in the case of senior sales and executive
management, the three year period) following the termination of this Agreement,
no SBC Entity will, directly or indirectly, through one or more of its
Affiliates, on behalf of itself or any other Person, recruit or otherwise
solicit or induce any employee of the RHD Entities or any of their successors to
terminate his or her employment relationship with the RHD Entities or any of
their successors. The foregoing will not, however, prohibit any SBC Entity from
publishing any general public solicitation of employment opportunities or
employing anyone who responds to such solicitation.

                                    ARTICLE 4

                             OTHER PRINT DIRECTORIES

         SECTION 4.1 OTHER PRINT DIRECTORIES. If SBC determines to outsource or
sell all of its print directory publishing business in any State or States
(excluding any such sale which also involves any other non-directory businesses
or assets of any SBC Entity), RHD will be entitled to receive notice of SBC's
intent to so outsource all or sell any such aspect, as the case may be, of its
publishing business and SBC will in good faith provide RHD with the opportunity
to participate in any bidding with respect to such outsourcing or sale process.

                                    ARTICLE 5

                                  MISCELLANEOUS

         SECTION 5.1 ASSIGNMENT. Except as provided in Sections 9.5 and 10.1 of
the Directory Services License Agreement, no Party may assign all or any of its
rights or obligations under the Agreement without the prior written consent of
the other Parties, except that any Party may assign all of its rights and
obligations under this Agreement (a) in connection with a sale of all or
substantially all of its assets or by merger or consolidation if the purchaser
assumes in writing all of the assigning Party's rights and obligations under
this Agreement in a form reasonably acceptable to the other Party and (b) to (i)
any of its Affiliates or (ii) any lender or any other party as collateral in
connection with any financing provided that no such assignment permitted by this
clause (b) will relieve such Party of any of its obligations under this
Agreement.

         SECTION 5.2 COSTS; EXPENSES. In addition to any rights and remedies
that the Parties may have under applicable law, if either Party breaches this
Agreement and the other Party seeks and obtains appropriate relief therefor,
then the non-breaching Party will be entitled to recover any reasonable costs or
expenses, including attorneys fees and disbursements, incurred by such
non-breaching Party in obtaining such relief from the breaching Party.

         SECTION 5.3 NOTICES. Any notice required or permitted under this
Agreement will be in writing and will be hand-delivered, sent by confirmed

                          SMARTPAGES RESELLER AGREEMENT

         THIS SMARTPAGES RESELLER AGREEMENT, dated as of this 1st day of

         Capitalized terms used but not defined herein shall have the meanings
assigned to them in the Directory Services License Agreement, dated as of the

Partners, DonTech II, Ameritech, SBC Directory Operations and SBC Knowledge
Ventures.

         In this Agreement, RHD and Publisher, on the one hand, and SBC,
Southwestern Bell and SBC Knowledge Ventures, on the other hand, are sometimes
referred to individually as a "Party" and collectively as the "Parties".

                                    RECITALS:

         A.       On the date of this Agreement, RHD, or one of its wholly owned

99% of the outstanding partnership interests in APIL Partners, (b) 47% of the

         B.       Southwestern Bell currently owns and operates an Existing IYP
Directory using the domain name "SMARTpages.com" (as of any determination date,
such Existing IYP Directory or any successor product which has become, as of
such determination date, the principal electronic directional advertising
product or service sold by Southwestern Bell outside the Territory is referred
to herein as "SMARTpages").

         C.       Southwestern Bell desires to grant Publisher, and Publisher
desires to obtain from Southwestern Bell, the exclusive right to sell Local IYP
Advertising (as defined in the Non-Competition Agreement) and the non-exclusive
right to sell National IYP Advertising (as defined in the Non-Competition
Agreement) for inclusion in SMARTpages to any Person physically located in the
Territory, in each case on the terms and conditions set forth in this Agreement
and the other Commercial Agreements.

         D.       The Purchase Agreement provides that the Parties will enter
into this Agreement as a condition to the closing of the transactions
contemplated by the Purchase Agreement.

<PAGE>

                                    AGREEMENT

         NOW, THEREFORE, in consideration of the premises and the mutual
representations, warranties, covenants and agreements set forth in this
Agreement and the other Commercial Agreements and the consummation of the
transactions contemplated by the Purchase Agreement and the other Commercial
Agreements, the Parties agree as follows:

         1.       GRANT OF RIGHTS. Subject to the terms and conditions of this
Agreement, Southwestern Bell hereby grants Publisher the exclusive right to sell
Local IYP Advertising and the non-exclusive right to sell National IYP
Advertising to any Person physically located in the Territory (an "Advertiser")
for inclusion in SMARTpages; provided, however, Publisher will not have the
right to sell any advertising for inclusion in SMARTpages to, or through a
certified marketing representative (a "CMR") for the account of, any Advertiser
that qualifies to place National (as defined in the Non-Competition Agreement)
white or yellow pages advertising under the current YPIMA (as defined in the
Non-Competition Agreement) minimum standards. Without limiting the foregoing,
Publisher will be permitted to determine the pricing for all Basic Listings and
Premium Products, in its sole discretion, except that Publisher will price
Premium Products (other than Local Premium Products) generally at rate card
rates, and, subject to compliance with Section 2 in the case of Basic Listings
and Section 3 in the case of Premium Products, will be entitled to all revenue
from the sale of such advertising.

         2.       BASIC LISTINGS.

                  (a)      During each year of the Term (as hereinafter
defined), Southwestern Bell will include on SMARTpages an unlimited number of
Basic Listings sold by Publisher, and Publisher will pay Southwestern Bell the
following monthly amounts, which shall be payable in installments monthly in
arrears:

</TABLE>

                  For purposes of this Agreement, "Basic Listings" means basic
local enhanced listings for inclusion in SMARTpages, which listings (i) are
accessible by users of SMARTpages searching listings within the Territory or any
smaller geographic area constituting a part thereof (e.g., local, regional or
Illinois statewide), and Publisher may make available to Advertisers that
purchase Basic Listings all such geographic areas then available on SMARTpages,
(ii) appear sorted in alphabetical order among the basic local

                                       -2-

<PAGE>

enhanced listing tier within the "featured businesses" or other substantially
comparable section of SMARTpages, (iii) will include, and Publisher may select
with respect to any Advertiser, any of the following information relating to an
Advertiser: (A) the business name, address and telephone number, (B) the brands
offered, (C) hours of operation, (D) payment options, (E) Internet links to a
website, (F) Internet links to a SMARTpages web page, (G) Internet links to maps
and driving directions and (H) Internet links to a customer's print ad;
provided, however, in the case of Internet links to certain websites or web
pages as specified in clauses (E), (F) and (H), Southwestern Bell will not be
responsible for providing the content for such websites or web pages, and (iv)
any other content or features which SMARTpages may from time to time decide in
its sole discretion to include in Basic Listings.

                  (b)      Southwestern Bell will place each Advertiser's Basic
Listings under any headings that Publisher may select among all headings then
available on SMARTpages (each, an "Existing Heading").

                  (c)      If any Advertiser purchases Basic Listings directly
from SMARTpages through self-fulfillment, Southwestern Bell will notify
Publisher of such purchase and remit to Publisher any amounts received by
Southwestern Bell from such sale within 30 days of receipt, after which
Publisher shall be responsible for servicing such Advertiser with respect to
such advertising. The foregoing shall not apply to any purchase of Premium
Products (as defined below) through self-fulfillment.

                  (d)      During the Non-Compete Term (as hereinafter defined),
Publisher will provide to Southwestern Bell free of charge all published
non-listing information relating to Advertisers which (i) is consistent with
what is then considered a Basic Listing, (ii) has been sold from time to time by
Publisher for any Existing IYP Directory or Future Electronic Directory and
(iii) is usable by Southwestern Bell on any of its Existing IYP Directories or
Future Electronic Directories (but subject to third party rights, which
Publisher will use its commercially reasonable efforts to assist Southwestern
Bell in obtaining) (collectively, the "Publisher Provided Information").
Southwestern Bell and Publisher will cooperate in good faith to agree upon the
format in which such published information will be delivered to Southwestern
Bell. During the Non-Compete Term, Southwestern Bell will include the Publisher
Provided Information in SMARTpages as a Basic Listing for which Publisher will
pay the monthly amounts specified in Section 2(a) above.

                  (e)      On the date of this Agreement, Southwestern Bell will
transfer to Publisher all rights it has to receive any payments from the sale of
advertising in the Territory by Southwestern Bell for inclusion in SMARTpages
prior to such date which have not been invoiced prior to the date of this
Agreement, and Publisher will remit to Southwestern Bell an amount equal to 50%
of the then current published rate card rate for any such advertising within 30
days of receipt.

                                       -3-

<PAGE>

         3.       PREMIUM PRODUCTS.

                  (a)      If Publisher sells any advertising product or service
included in SMARTpages other than Basic Listings (each, a "Premium Product"),
then Publisher will pay to Southwestern Bell the lesser of (i) 50% of the
then-current published rate card rate for such Premium Product and (ii) the
price then available for such Premium Product on a most-favored-customer basis
for similarly situated customers that are purchasing equivalent volumes and
types of advertising (the "Premium Product Rate"). Premium Products may include,
but are not limited to: (x) any improved placement product, service or
functionality offered on SMARTpages, whether or not such product, service or
functionality exists as of the date of this Agreement, including "Look Here
First", premium banner and trademark premium banner, trademark banner, single
banner or double banner, enhanced placement listing and enhanced placement
listings with logo products (each, an "Improved Placement Product"), which in
each case will include click-to-call functionality, (y) any headings other than
Existing Headings and (z) any advertising product or service accessible by users
of SMARTpages searching listings outside the Territory. With respect to any
Improved Placement Product sold by Publisher which it provides to Southwestern
Bell in a "production ready" format, the Parties will negotiate in good faith an
appropriate reduction in the price relative to the Premium Product Rate for such
Improved Placement Product.

                  (b)      If any Advertiser purchases Premium Products that are
accessible solely by users of SMARTpages searching listings within the Territory
(each, a "Local Premium Product") directly from SMARTpages through
self-fulfillment, Southwestern Bell will notify Publisher of such purchase and
remit to Publisher any amounts received by Southwestern Bell from such sale
within 30 days of receipt, after which (i) Publisher (x) will pay Southwestern
Bell the Premium Product Rate for such purchase and (y) shall be responsible for
servicing such Advertiser with respect to such advertising and (ii) such Local
Premium Products will be deemed to be sold by Publisher in accordance with
Section 3(a) above.

         4.       NATIONAL SALES. Publisher will refer to Southwestern Bell all
sales of advertising to, or through a CMR for the account of, any Advertiser
that qualifies to place National advertising under the current YPIMA minimum
standards. Within 30 days following the end of each year of the Term,
Southwestern Bell will pay to Publisher an aggregate amount equal to 3.0% of
Southwestern Bell's gross revenues during the most recent prior year from the
sale of advertising on SMARTpages through CMRs (the "Revenue Share"). Upon
Publisher's request, Southwestern Bell will provide Publisher or its
representatives with reasonable access once a year to the books and records and
other documents of Southwestern Bell that Publisher may reasonably request
concerning the calculation of the Revenue Share for the prior year.

         5.       OTHER DIRECTORIES. RHD and its Subsidiaries may resell or
enter into any other relationship to sell or benefit from the sale of
advertising for inclusion in any other Existing IYP Directory or Future
Electronic Directory, other than in the Territory with respect to any Existing
IYP Product or Future Electronic Directory owned or operated by

                                       -4-

<PAGE>

Verizon Communications Inc. or any of its Affiliates (each, a "Prohibited IYP
Directory") unless at such time Southwestern Bell also sells any advertising for
inclusion in such Prohibited IYP Directory.

         6.       PUBLISHER OBLIGATIONS.

                  (a)      Standards. Publisher will comply with all advertising
standards and guidelines for SMARTpages advertising that Southwestern Bell may
issue from time to time and provide to Publisher (as modified in accordance with
the next sentence, the "IYP Advertising Policies"). Southwestern Bell may, in
its sole discretion, change the IYP Advertising Policies. Southwestern Bell will
notify Publisher promptly of any such change a reasonable period before it
becomes effective. Southwestern Bell will not be obligated to accept from
Publisher, and may at any time remove from SMARTpages, any advertising sold by
Publisher that Southwestern Bell reasonably determines does not comply with the
IYP Advertising Policies.

                  (b)      Customization. Publisher may request programming
changes for SMARTpages and will be responsible for all costs and expenses
incurred by Southwestern Bell to implement such changes if such changes are
implemented only with respect to the Territory; provided, however, prior to
incurring any such costs and expenses, Southwestern Bell will provide Publisher
with an estimate thereof and will not commence any such programming changes
without Publisher's prior approval of such estimate; and provided, further, that
this Section 6(b) will not obligate Southwestern Bell to agree to implement any
such changes.

         7.       NON-COMPETITION. During the Non-Compete Term, neither SBC nor
any of its Subsidiaries will sell any Local IYP Advertising for any Existing IYP
Directory or Future Electronic Directory. For purposes of this Agreement,
"Non-Compete Term" means the period commencing on the date of this Agreement and
ending on the later of (i) the fifth anniversary of the date of this Agreement
and (ii) the 18-month anniversary of the date on which Publisher terminates this
Agreement pursuant to Section 8 below.

         8.       CONSORTIUM PRODUCT. If Southwestern Bell enters into a
strategic arrangement with one or more third parties regarding a successor
product to SMARTpages (a "Consortium Product"), Southwestern Bell will use
commercially reasonable efforts to secure for Publisher the right to sell
advertising to Advertisers for such Consortium Product under the same terms and
conditions as this Agreement. If despite such efforts Southwestern Bell is
unable to secure such right on or prior to the date on which the Consortium
Product is first generally made available to the public, then on or before such
date Southwestern Bell will propose amendments to this Agreement as required to
be compatible with such strategic arrangement; provided, that Southwestern Bell
may not amend the annual rates for Basic Listings set forth in Section 2 of this
Agreement or clause (ii) of the definition of Premium Product Rate and will
negotiate with Publisher in good faith any amendments to the fees for Premium
Products included in clause (i) of the definition of Premium Product Rate (a
"Successor Proposal"). Within 30 days of receiving a Successor Proposal,
Publisher may, in its sole discretion, (i) accept

                                       -5-

<PAGE>

the Successor Proposal and enter into a new IYP Reseller Agreement on the terms
and conditions of the Successor Proposal or (ii) terminate this Agreement
without any further obligation or liability except as provided in Sections 2(a)
and 2(d) of this Agreement.

         9.       TERM. The term of this Agreement shall commence on the date of
this Agreement and will continue for a term of five years (the "Term");
provided, however, this Agreement will terminate immediately and without any
further action when (i) the Directory Services License Agreement expires in
accordance with its terms, is terminated by or on behalf of Southwestern Bell in
accordance with its terms or is terminated by or on behalf of Publisher in
accordance with its terms or otherwise or (ii) Publisher terminates this
Agreement pursuant to Section 8 above, and provided, further, that if this
Agreement terminates pursuant to Section 8 above, then Sections 2(a), 2(d) and 7
of this Agreement will survive during the Non-Compete Term. Unless earlier
terminated, the Parties agree to negotiate in good faith to extend the term of
this Agreement; provided, however, that neither Party will be obligated to agree
to any such extension of the Term.

         10.      SMARTPAGES MARK.

                  (a)      Subject to the terms and conditions of this
Agreement, each of Southwestern Bell and SBC Knowledge Ventures (each, an "IYP
Licensor") hereby grants to Publisher a non-transferable (except as provided in
Section 12), non-exclusive right to use for the Term the mark "SMARTpages" (the
"SMARTpages Mark") on sales collateral, contracts, invoices, customer
correspondences and advertising and promotional materials solely in connection
with soliciting and selling advertising to Advertisers for inclusion in
SMARTpages as permitted by this Agreement and oral communications with respect
thereto.

                  (b)      Publisher will comply with all standards for usage of
the SMARTpages Mark, as issued from time to time by an IYP Licensor to Publisher
(the "Usage Standards"), provided, that such IYP Licensor will notify Publisher
of any such Usage Standards a reasonable period before they become effective.
During the Term, any IYP Licensor may request from time to time, and Publisher
agrees to provide, access to or samples of Publisher's public usage of the
SMARTpages Mark to ensure Publisher's compliance with the Usage Standards.
Immediately upon termination of this Agreement, Publisher will cease displaying
and using the SMARTpages Mark on any materials and destroy or turn over to IYP
Licensors any materials using the SMARTpages Mark; provided, however, that
Publisher may retain copies of materials containing the SMARTpages Mark for
archival purposes.

                  (c)      Publisher shall not use the SMARTpages Mark or the
name "SMARTpages" in its corporate or business name, nor allow its Affiliates to
use the SMARTpages Mark or the name "SMARTpages" in their respective corporate
or business names, except that any use of the SMARTpages Mark by Publisher in
accordance with Section 10(a) above will not violate this Section 10(c). IYP
Licensors reserve all rights in and to the SMARTpages Mark not otherwise
expressly granted to Publisher under Section 10(a),

                                       -6-

<PAGE>

                  (d)      Publisher shall promptly notify IYP Licensors of any
infringement of the SMARTpages Mark that comes to its attention. Publisher shall
cooperate with IYP Licensors to take such actions as IYP Licensors in their sole
discretion may consider necessary to protect the SMARTpages Mark with all
expenses being borne by IYP Licensors.

                  (e)      Each IYP Licensor represents and warrants that it has
the power and authority to enter into this Agreement and grant the rights it is
granting under this Agreement.

         11.      INDEMNIFICATION.

                  (a)      Publisher Indemnity. Publisher will defend, hold
harmless and indemnify Southwestern Bell and each of its Affiliates, officers,
directors, shareholders, employees, contractors, agents and representatives from
and against any and all Losses and Expenses arising out of, resulting from or
based upon any pending or threatened claim, action, proceeding or suit by any
third party, whether based on contract, tort or otherwise, arising out of or in
connection with (i) any breach of this Agreement by RHD or Publisher, (ii) the
use of the SMARTpages Mark by Publisher in violation of this Agreement, (iii)
any advertising for inclusion in SMARTpages provided by Publisher to
Southwestern Bell pursuant to this Agreement and (iv) any published non-listing
information for Existing IYP Directories or Future Electronic Directories
provided to any SBC Entity by any RHD Entity (other than any such information
which no RHD Entity had any role in creating, in which case the applicable RHD
Entity will assign any indemnification rights such RHD Entity may have with
respect to such information) pursuant to Section 2(d) of this Agreement.

                  (b)      Southwestern Bell Indemnity. Southwestern Bell will
defend, hold harmless and indemnify Publisher and each of its Affiliates,
officers, directors, shareholders, employees, contractors, agents and
representatives from and against any and all Losses and Expenses arising out of,
resulting from or based upon any pending or threatened claim, action, proceeding
or suit by any third party, whether based on contract, tort or otherwise,
arising out of or in connection with (i) any breach of this Agreement by SBC or
Southwestern Bell or (ii) the use of the SMARTpages Mark by Publisher in
accordance with the terms of this Agreement.

                  (c)      Procedure. Promptly after receipt by the indemnified
party of notice by a third party of a claim or of the commencement of any action
or proceeding with respect to which such indemnified party may be entitled to
receive payment from the other party for any Losses or Expenses, such
indemnified party will notify the indemnifying party of the notice of such claim
or of the commencement of such action or proceeding; provided, however, that the
failure to so notify the indemnifying party will relieve the indemnifying party
from liability under this Agreement with respect to such claim, action or
proceeding only if, and only to the extent that, such failure to notify the
indemnifying party results in the forfeiture by the indemnifying party of rights
and defenses otherwise available to the indemnifying party with respect to such
claim, action

                                       -7-

<PAGE>

or proceeding. The indemnifying party will have the right, upon written notice
delivered to the indemnified party, to assume the defense of such claim, action
or proceeding, including the employment of counsel reasonably satisfactory to
the indemnified party and the payment of the fees and disbursements of such
counsel. In any claim, action or proceeding with respect to which
indemnification is being sought hereunder, the indemnified party or the
indemnifying party, whichever is not assuming the defense of such action, will
have the right to participate in such matter and to retain its own counsel at
such party's own expense. The indemnifying party or the indemnified party, as
the case may be, will at all times use reasonable efforts to keep the
indemnifying party or the indemnified party, as the case may be, reasonably
apprised of the status of the defense of any action the defense of which they
are maintaining and to cooperate in good faith with each other with respect to
the defense of any such action. If the indemnifying party has assumed the
defense of a claim, action or proceeding, no indemnified party may settle or
compromise such matter or consent to the entry of any judgment with respect to
such matter without the prior written consent of the indemnifying party. An
indemnifying party may not, without the prior written consent of the indemnified
party, settle or compromise any claim or consent to the entry of any judgment
with respect to which indemnification is being sought hereunder unless (i)
simultaneously with the effectiveness of such settlement, compromise or consent,
the indemnifying party pays in full any obligation imposed on the indemnified
party by such settlement, compromise or consent (ii) such settlement, compromise
or consent contains a complete release of the indemnified party and its
Affiliates and their respective directors, officers and employees and (iii) such
settlement, compromise or consent does not contain any equitable order, judgment
or term which in any manner affects, restrains or interferes with the business
of the indemnified party or any of the indemnified party's Affiliates. In the
event an indemnified party will claim a right to payment pursuant to this
Agreement not involving a third party claim covered by this Section 11, such
indemnified party will send written notice of such claim to the appropriate
indemnifying party. Such notice will specify the basis for such claim.

         12.      BINDING EFFECT; ASSIGNMENT. This Agreement will be binding on
and inure to the benefit of the Parties, and their respective successors and
permitted assigns. Except as provided in Section 10.1 of the Directory Services
License Agreement, no Party may assign all or any of its rights or obligations
under this Agreement without the prior written consent of the other Party,
except that any Party may assign all of its rights and obligations under this
Agreement (a) in connection with a sale of all or substantially all of its
assets or by merger or consolidation if the purchaser assumes in writing all of
the assigning Party's rights and obligations under this Agreement in a form
reasonably acceptable to the other Party, and (b) to any of its Affiliates; or
(ii) any lender or other party as collateral in connection with any financing,
provided, that no such assignment permitted by this clause (b) will relieve such
Party of any of its obligations under this Agreement.

         13.      NOTICES. Any notice required or permitted under this Agreement
will be given in accordance with the notice provisions of the Directory Services
License Agreement.

         14.      REMEDIES. The Parties agree that all disputes or controversies
arising out of or relating to this Agreement shall be resolved using the
procedures set forth in the Directory Services License Agreement, including
Sections 18.1, 18.4 and 18.6, which are incorporated herein by this reference.

         15.      GOVERNING LAW; FORUM SELECTION. This Agreement shall be
governed, construed and enforced in accordance with the laws of the State of New
York without reference to the conflict of laws principles thereof. Each Party
irrevocably submits to the jurisdiction of the Federal and state courts in the
Borough of Manhattan, The City of New York for the resolution of any and all
disputes relating to this Agreement and waives any and all objections it might
otherwise have to such jurisdiction and venue.

         16.      AMENDMENT; WAIVER. No amendments, deletions, additions or
other modifications to this Agreement will be binding unless evidenced in
writing and signed by an officer of each of the respective Parties hereto. No
waiver of any provision of this Agreement, and no consent to any default under
this Agreement, will be effective unless the same is in writing and signed by an
officer of the Party against whom such waiver or consent is claimed. In
addition, no course of dealing or failure of a Party strictly to enforce any
term, right or condition of this Agreement will be construed as a waiver of such
term, right or condition. Waiver by either Party of any default by the other
Party will not be deemed a waiver of any subsequent or other default.

         17.      RELATIONSHIP. Nothing contained in this Agreement shall be
construed to create the relationship of employer and employee between the
Parties, franchiser - franchisee, or to make the Parties partners, joint
venturer or co-employer of the other, or result in joint service offerings to
their respective customers. The relationship between the Parties is that of an
independent contractor. Each Party will be solely responsible for such Party's
employees, including compliance with all employment laws, regulations, and rules
and payment of wages, benefits and employment taxes such as Social Security,
unemployment, workers compensation and federal and state withholding with
respect to such employees.

         18.      HEADINGS. The headings and numbering of sections and
paragraphs in this Agreement are for convenience only and will not be construed
to define or limit any of the terms in this Agreement or affect the meaning or
interpretation of this Agreement.

         19.      SURVIVAL. Any liabilities or obligations of a Party for acts
or omissions occurring prior to the cancellation or termination of this
Agreement and any obligations of a Party under any other provisions of this
Agreement which, by their express terms, are contemplated to survive (or be
performed after) termination of this Agreement (subject to any time limitations
specified therein) will survive the cancellation or termination of this
Agreement.

         20.      ENTIRE AGREEMENT. The Commercial Agreements constitute the
entire understanding and agreement of the Parties concerning the subject matter
of this Agreement and the other Commercial Agreements, and supersede any prior
agreements,

                                       -9-

<PAGE>

representations, statements, understandings, proposals, undertakings or
negotiations, whether written or oral, with respect to the subject matter set
forth in the Commercial Agreements.

         21.      SEVERABILITY. If any term, condition or provision of this
Agreement is held to be invalid or unenforceable for any reason, such invalidity
will not invalidate the entire Agreement, unless such construction would be
unreasonable. This Agreement will be construed as if it did not contain the
invalid or unenforceable provision or provisions, and the rights and obligations
of each Party will be construed and enforced accordingly, except that in the
event such invalid or unenforceable provision or provisions are essential
elements of this Agreement and substantially impair the rights or obligations of
either Party, the Parties will promptly negotiate in good faith a replacement
provision or provisions.

         22.      COMPLIANCE WITH LAWS AND REGULATIONS. Each Party will comply
with all federal, state, and local laws, regulations, rules, ordinances and
orders relating to the performance of its obligations and the use of services
provided under this Agreement, including any rulings, modifications, regulations
or orders of the Federal Communications Commission and/or any applicable state
utility commission to the extent this Agreement is subject to the jurisdiction
of such regulating authority.

         23.      THIRD PARTY BENEFICIARIES. This Agreement is intended solely
for the benefit of the Parties, and no third-party beneficiaries are created by
this Agreement. This Agreement does not provide and should not be construed to
provide third parties with any remedy, claim, liability, reimbursement, cause of
action or other privilege.

         24.      COUNTERPARTS. This Agreement may be executed in any number of
counterparts, and each such counterpart will be deemed to be an original
instrument, but all such counterparts will constitute but one agreement. This
Agreement will become effective when one or more counterparts have been signed
by each and delivered to the other Party, it being understood that the Parties
need not sign the same counterpart.

         25.      SOUTHWESTERN BELL. For purposes of this Agreement,
"Southwestern Bell" means, collectively, Southwestern Bell, Inc., any Person
into whom Southwestern Bell, Inc. merges or consolidates and any other Person to
whom SMARTpages or all or substantially all of the business or assets of
Southwestern Bell, Inc. is transferred. Prior to the time that the defined term
"Southwestern Bell" applies to any Person other than Southwestern Bell, Inc.,
Southwestern Bell, Inc. shall cause such Person to enter into a written
agreement, in form and substance reasonably satisfactory to RHD pursuant to
which such Person assumes all of Southwestern Bell's obligations under this
Agreement. From and after such assumption, such Person shall also be deemed to
be Southwestern Bell, Inc. for purposes of this Agreement, but such assumption
shall not discharge or release any other Persons to which such defined term then
applies.
