                                  WITNESSETH:

        WHEREAS, Ameritech to the extent permitted by law, is the owner of all

        WHEREAS, Licensee desires to obtain the Listing Information which

        WHEREAS, Ameritech is willing to license the right to use Listing
Information to Licensee strictly pursuant to the provisions of this Agreement
and for no other purpose.

        NOW, THEREFORE, in consideration of the mutual covenants hereinafter

        of extraction from Ameritech's listing system.

1.1     All requests for Ameritech Listing Information supplied to Licensee
        pursuant to this Agreement shall be provided upon the submission by
        Licensee of an appropriate "Request for Listing Information" form, the
        current sample of which appears as Appendix A, attached hereto and
        incorporated herein ("Request").
   2
1.2     Each Request shall specify the Listing Information requested according
        to either the Ameritech Exchange Areas, zip code area or community and
        shall include the format in which such Listing Information shall be
        furnished. For purposes of this Agreement, "Exchange Area" means the
        central office serving area represented by the first three digits of a
        telephone exchange within an area code.

1.3     Each Request shall be subject to appropriate license fees and other
        charges as set forth in Paragraph 3 herein. Any Request submitted by
        Licensee for a Base File only (as defined in Appendix B) shall be
        subject to a minimum charge of three hundred dollars ($300).

1.4     Each Request shall be provided to Ameritech no later than thirty (30)
        calendar days prior to the date by which Listing Information and related
        Additional Services are scheduled to be provided to the Licensee. It
        shall contain the name of the Licensee's Directory, the publication
        date, Additional Services, if any, the date mutually agreed upon for
        provision of same to Licensee ("Provision Date") and identification
        specifications for the requested Ameritech Listing Information.

ARTICLE TWO-LICENSE

2.0     Subject to the provisions of this Agreement, Ameritech grants to
        Licensee during the term of this Agreement a non-exclusive,
        non-transferable License for one (1) time use of Listing Information
        provided pursuant to each Request, such use to be limited to the
        compilation, production, publication and distribution of the Licensee
        Directory identified in the particular Request. This License Agreement
        applies to and is effective only to those listings contained in
        Ameritech's records with respect to business and residence customers and
        excludes all non-published and non-listed subscribers.

2.1     Licensee agrees not to use or publish any lists or Listing Information
        which it has been advised by Ameritech or otherwise has reason to know
        is incorrect or incomplete.

2.2     Ameritech reserves the right to make changes in the form, content or
        scope of its Listing Information; makes no representation that it will
        continue to provide the Listing Information in its current form in the
        future; and reserves the right to modify its form, to change the manner
        in which it is provided. Ameritech shall notify Licensee in writing of
        any such change not less than thirty (30) days prior to implementation.

2.3     Any source material containing Listing Information furnished by
        Ameritech hereunder, whether or not used by Licensee for the purpose
        stated herein, shall remain the property of Ameritech and Licensee
        shall, upon request from Ameritech, but in no event later than thirty
        (30) days following the termination of this Agreement as stated in
        Paragraph 6.5 herein, return or destroy such source material.



                                       2
   3
2.4     If Listing Information provided hereunder includes any listings or other
        information that is the property of a telephone company other than
        Ameritech whether pursuant to release, by mistake or otherwise, Licensee
        must enter into a separate license agreement with such telephone company
        if Licensee desires to use or publish any such listing or other
        information in a Licensee Directory.  Upon Ameritech's request, Licensee
        shall furnish a copy of such license agreement to Ameritech.

2.5     The License granted herein shall be non-assignable and Licensee shall
        have no right to sub-license or permit any other publisher or person to
        use the Listing Information of any information extracted therefrom
        except for the purpose of assisting in the compilation, production,
        publication or distribution of the Licensee Directory identified in the
        particular Request. Licensee shall take reasonable and prudent steps to
        prevent disclosure of the source material containing Listing Information
        at least equal to the steps taken by it to protect its own similar
        proprietary information, including adequate computer security measures
        to prevent unauthorized access to the Listing Information when contained
        in any data base.

2.6     Any "Updates", "Advanced Listing Orders" or "New Connect Listings" (as
        defined in Appendix B) requested by Licensee, whether provided daily,
        weekly, or monthly shall not be used to compile, publish or update a
        directory or compile or publish a separate list but may be used to
        generate leads for sales of yellow pages classified advertising in
        Licensee's Directory. In no event shall Licensee use, disclose or
        reproduce any Ameritech service order information or other information
        furnished hereunder or permit anyone but its duly authorized employees
        or agents to inspect or use the same, except for the purposes expressly
        provided herein.

ARTICLE THREE - LICENSEE FEE

3.0     Fees as set forth in the Appendix B and any transportation expenses
        shall be assessed for the Listing Information and related Additional
        Services specified in 3.2 below.  Amounts due hereunder shall be
        invoiced fifty percent (50%) upon receipt of a Request and fifty percent
        (50%) sixty (60) days after delivery of the Listing Information or upon
        publication of a Licensee Directory containing such Listing Information,
        whichever first occurs.  All fees owed to Ameritech under this Agreement
        shall be paid by Licensee within thirty (30) days of invoice date.

3.1     Listing Information - Licensee agrees to pay to Ameritech all applicable
        license fees and per-listing charges and such state, municipal and
        federal taxes as may be applicable to such transaction (hereinafter
        "Fees") for each submitted Request as are shown on Appendix B.


3.2     Additional Services.

        (i)     Photocomposition pages - Upon receipt of a Request ordering
                photocomposition pages, Ameritech shall provide Licensee with



                                       3

   4

                 photocomposed pages of the requested Listing Information for
                 Licensee's Directory.  In addition to the Fees described in
                 Paragraph 3.1 herein, Licensee shall pay to Ameritech a
                 processing charge as set forth in Appendix B for each
                 photocomposed page provided to it.

         (ii)    Customization services - Customization and other special
                 programming for non-standard extracts e.g. sorted by street
                 address, as noted in Appendix B, are also available to
                 Licensee, upon receipt of a Request by Licensee.  For each
                 Request requiring special programming, Licensee shall pay to
                 Ameritech a one time fee set forth in Appendix B in addition
                 to the fees described in Paragraph 3.1.

3.3      The per listing charge as specified in Appendix B herein entitles
         Licensee to a one time publication of each listing so provided.  In
         the event any Licensee Directory contains more than one reference to
         any Listing Information (for example, in both an alphabetical and a
         classified listing section), and only one per listing charge will be
         assessed.

3.4      Increase or Decrease in Fees or Charges, All Fees shall be fixed
         during the period of this Agreement.  Charges for Additional Services
         specified in Paragraph 3.2 herein may be increased by Ameritech at any
         time upon thirty (30) days prior written notice to Licensee.
         Notwithstanding the foregoing, all Fees and other charges herein may
         be decreased by Ameritech at any time without notice.

3.5      Notwithstanding the provisions of paragraph 3.0 above, Ameritech
         reserves the right to require receipt of payment in full for any
         Listing Information or Additional Services prior to scheduled shipment
         to Licensee.  The payment in full will include, but is not limited to,
         estimated charges made for items requested by Licensee and contained
         in the Request.  The payment of estimated charges by Licensee to
         Ameritech shall be credited against the charges due and payable with
         the final invoice.  Any or all remaining payment shall be due and
         payable upon thirty (30) days of receipt of an invoice.

ARTICLE FOUR - IDENTIFICATION OF LICENSEE

4.0      Licensee shall, to the extent legally permissible, include a proper
         copyright notice in its name in each Licensee Directory published by
         it and Licensee shall use its best efforts to protect and maintain the
         validity of said copyright.  Nothing contained in this Agreement shall
         restrict, impair or diminish the proprietary interest of Ameritech in
         any Ameritech Directory or the Listing Information furnished to the
         Licensee, and Ameritech shall continue to copyright directories
         published by it or on its behalf without regard to the prior
         publication and copyright of any Licensee Directory.  Upon request by
         Ameritech, Licensee agrees to execute and deliver to Ameritech all
         assignments, documents and directories necessary to carry out the
         intent of this Paragraph; however, Licensee shall deliver to Ameritech
         one copy of each edition of the





                                       4

         by Ameritech.  This copy shall be furnished without charge within ten
         (10) working days following the publication of Licensee's Directory.
         Ameritech further reserves the right to examine at reasonable times
         Licensee's security practices.

4.1      Licensee shall not make any representation to the public, prospective
         advertisers or others, express or implied, written or oral, which
         would give the impression that Licensee and/or any Licensee Directory
         is the same as, a part of, or associated with Ameritech or any
         Ameritech Directory; nor shall Licensee canvass for or publish any
         type of telephone directory in the name of Ameritech, or use, except
         as authorized herein, Listing Information or any Ameritech or any
         affiliated Ameritech Company advertising contained in Ameritech
         Directories.

4.2      Licensee shall not publish any Licensee Directory in such form as may
         tend to cause or create confusion or be identified with any Ameritech
         Directory, and further, Licensee agrees that its employees, agents and
         representatives shall not use any advertisement, order form, billing
         invoice, stationery, promotional material or any other material or
         device which would tend to create or imply association with or
         sponsorship by Ameritech or any affiliated Ameritech Company.

4.3      Licensee shall not word the title of any Licensee Directory in any
         manner which would tend to indicate that it is an Ameritech Directory.
         Licensee shall use its own name or trade name (in full or in part) on
         the cover of each Licensee Directory and shall use a similar
         designation in all of its advertising, canvassing and billing for such
         Licensee Directory.

4.4      Licensee shall not reproduce or use in a classified portion (or in any
         other part) of any Licensee Directory stock graphic cuts or filler
         material or text which is proprietary to Ameritech or used by
         Ameritech or its affiliated companies in any Ameritech Directory,
         unless such matter was furnished to Licensee by the advertiser and
         owned by the advertiser.

4.5      Licensee agrees to print month and year of publication on the front
         cover of each of its Directories and to publish the following
         statement on the masthead page of each Directory:

                 Listings of Ameritech, contained herein were transcribed by
                 Telecom * USA Publishing Company pursuant to a license from
                 Ameritech and may not be reproduced in whole or in part, or in
                 any form whatsoever, without the written permission of
                 Ameritech.

5.0      Licensee shall defend, indemnify, and hold harmless Ameritech and its
         officers, employees, affiliates, agents, assigns, representatives and
         licensees from and against all loss, liability, damage and expense
         (including all costs and reasonable attorneys' fees) arising out of
         any demand, claim, suit or judgment by a third party related to
         Ameritech supplying or its failure to supply any listing or Listing
         Information hereunder, or Licensees use or misuse of the same; or
         related to any error, inclusion or omission in any Licensee Directory,
         regardless whether any such demand, claim or suit by such third party
         is brought jointly against the Licensee and Ameritech or against
         Ameritech alone; provided, however, that in the event of any such
         demand, claim or suit, Ameritech may, at its option and at its
         expense, assume and undertake its own defense or assist in the defense
         of Licensee provided, however, that Ameritech shall not enter into any
         settlement of any such demand, claim or suit without prior written
         consent of Licensee.

5.1      Ameritech's responsibility for delivery of the Listing Information
         shall be discharged upon its delivery to Licensee's specified courier.
         If the Listing Information provided to Licensee by Ameritech is not
         that as stated in the Request, Ameritech shall, upon request, attempt
         to provide those listings identified in the particular Request without
         additional cost to Licensee.  Such request must be made within thirty
         (30) calendar days of Licensee's receipt of the Listing Information
         and shall include the original Listing Information provided in error.

5.2      The lists and Listing Information are provided "AS IS"; Ameritech does
         not warrant or represent that any lists or Listing Information made
         available to Licensee pursuant to this Agreement are correct or
         complete; and, Licensee hereby releases Ameritech from any liability
         due to errors, inclusions or omissions in the lists or Listing
         Information provided hereunder; provided however Licensee shall be
         entitled to refund of the amount paid for any individual listing to
         the extent such listing is found to be inaccurate or incomplete.

5.3      THE REMEDY STATED IN PARAGRAPH 5.1 and 5.2 HEREOF SHALL BE LICENSEE'S
         SOLE AND EXCLUSIVE REMEDY WITH RESPECT TO THE PROVISION OF LISTS AND
         LISTING INFORMATION HEREUNDER, AMERITECH MAKES AND LICENSEE RECEIVES
         NO WARRANTY, EXPRESS OR IMPLIED, AND THERE ARE EXPRESSLY EXCLUDED ALL
         WARRANTIES OR MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
         AMERITECH SHALL HAVE NO LIABILITY WITH RESPECT TO ITS OBLIGATIONS
         UNDER THIS AGREEMENT FOR DIRECT, CONSEQUENTIAL EXEMPLARY OR INCIDENTAL
         DAMAGES EVEN IF IT HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
         DAMAGES.

ARTICLE SIX - MISCELLANEOUS

6.0      Non-Exclusivity - Nothing in this Agreement or elsewhere shall give
         Licensee any exclusive right to the use of the Listing Information and
         Ameritech shall be free at any time to grant similar Licenses to
         others under the same or different terms and conditions as Ameritech
         in its sole discretion may determine.

6.1      Force Majeure - Performance by Ameritech shall be excused by reason
         of natural disaster; labor difficulty; civil disorder; acts of God;
         statute, ordinance or regulation hereinafter enacted, promulgated or
         entered by a court or government agency of competent jurisdiction; or
         by reason of any other cause beyond the reasonable control of
         Ameritech.

6.2      Survival of Obligations - The provisions of this Agreement that by
         their sense and context are intended to survive the termination of
         this Agreement shall so survive and continue in effect in accordance
         with their terms.

6.3      Governing Law - The validity, construction and enforceability of this
         Agreement shall be governed by the laws and regulations of the State
         of Illinois.

6.4      Severability - In the event any one or more of the provisions of this
         Agreement shall for any reason be held to be invalid, illegal or
         unenforceable, the remaining provisions of this Agreement shall be
         unimpaired, and the valid, illegal or unenforceable provisions shall
         be replaced by a mutually acceptable provision, which being valid,
         legal and enforceable, comes closest to the intention of the parties
         underlying the invalid, illegal or unenforceable provision.

6.5      Term and Termination

         (i)     This Agreement shall commence as of the date noted in the
                 introductory paragraph of this Agreement, and shall continue
                 for a period of 36 months (the "Term"); provided however, if
                 Licensee violates any material provisions of this Agreement,
                 Ameritech may immediately terminate this Agreement without
                 notice thereof to Licensee, and seek injunctive relief and all
                 damages and other remedies available to it by law or equity.
                 Failure of Ameritech to enforce or insist upon compliance with
                 any provisions of this Agreement shall not constitute a waiver
                 thereof nor derogate from Ameritech the right to damages or
                 any other relief.  Subject to this Paragraph, termination of
                 the Agreement shall not affect Licensee's right to use the
                 material or information furnished prior to the effective date
                 of the termination solely for the purpose permitted by this
                 Agreement.

         (ii)    In the event this Agreement is terminated by Licensee prior to
                 the expiration of the Term, Licensee shall be responsible for
                 paying the difference between the per listing charge
                 associated with this Agreement Term and the higher per listing
                 charge specified in Section I of Appendix B hereto for the
                 actual period this Agreement remains in effect.

                 damages or remedies available to Ameritech in law or in
                 equity.  Termination of this Agreement by Ameritech shall not
                 relieve Licensee of the obligation to pay all amounts owing to
                 Ameritech as of the date of termination or any of its other
                 obligations contained herein.
