         d.       ANSWER STANDARD. Metro One shall, except as provided in
                  Section 22 ("Force Majeure") below, provide sufficient

                  calls within a calendar month within each Calling Area is
                  answered in four (4) rings (24 seconds) or less. Metro One
                  shall use commercially reasonable efforts to answer all calls
                  within four (4) rings (24 seconds) or less. Each call shall be

         g.       SYSTEM ACCURACY. Metro One shall use all prudent business
                  measures to keep the System accurate to the same degree as the
                  database of the LEC for listings within the Call Completion
                  Area. In the event Metro One does not have sufficient
                  information in the System to provide basic listing data, it
                  shall utilize such other sources as commercially reasonable,
                  at no additional charge to the Mobile Carrier, to provide the
                  requested EDA services. Notwithstanding the foregoing, Metro
                  One shall be excused from performance to the extent that any
                  LEC or other Metro One selected data provider does not make
                  data available to Metro One under commercially reasonable
                  terms acceptable to Metro One in its sole discretion. In the
                  event Metro One does not have sufficient information in the
                  System to provide any one of the EDA services, it shall
                  utilize such other sources as necessary to provide the
                  requested EDA services, including, without limitation, the
                  back-up database provided as an on-line service by the LEC or
                  LEC operator delivered directory assistance. In the event that
                  either (i) a Caller requests the LEC directory assistance
                  operator, or (ii) Metro One cannot provide any one of the
                  requested EDA services, Metro One shall route a Caller's
                  telephone call to the LEC directory assistance operator. In
                  such a case, Metro One shall charge the Mobile Carrier the per
                  call fee in Section 9 (Payment) only, not the LEC's fees.

         h.       RAPID PROVISION OF SERVICES. Metro One shall ensure that
                  Subscribers obtain each desired telephone number or are
                  connected to such number without unnecessary delay after
                  requesting such number or connection from Metro One's
                  Operator. Metro One shall ensure that such data or connection
                  is provided to each

4-AGREEMENT FOR ENHANCED DIRECTORY ASSISTANCE SERVICES
<PAGE>

                  such connection cannot be made due to busy signal or other
                  impediment beyond Metro One's control.

         i.       CHANGE REQUESTS. Mobile Carrier may from time to time request
                  additions, enhancements, deletions, or other changes
                  ("Change") to the EDA Services. Metro One shall promptly
                  implement the Change provided that (1) the technology required
                  to implement the Change is readily available and reliable and
                  commercially reasonable, and (2) the Parties have agreed in
                  writing to any rate adjustment resulting from such Change. The
                  Parties shall negotiate in good faith with respect to any rate
                  adjustment. Metro One is not obligated to provide any Change
                  without such written agreement.

         j.       CALL COMPLETION. Metro One's operators shall ensure that the
                  call is properly connected, but shall not otherwise monitor,
                  record, listen to or divulge the contents of any
                  communications, or any other information regarding Subscribers
                  or calls unless authorized by the Subscriber. Metro One and
                  Mobile Carrier may monitor Metro One processing portions of
                  calls solely for quality control purposes. Unless otherwise
                  requested by a Subscriber, Metro One shall remain accessible
                  to the Subscriber throughout the completed call through the
                  use of a system which will enable the Subscriber to recall
                  Metro One's operator.

         k.       GREETING AND CLOSING. Metro One shall answer all calls made to
                  the EDA Numbers with a greeting and closing to be provided by
                  each Mobile Carrier. Such greeting shall not exceed five (5)
                  seconds and such closing shall not exceed twelve (12) seconds
                  in length. All such greetings and closings may be delivered by
                  means of an automated voice playback system. Each Mobile
                  Carrier may change its greeting or closing upon thirty (30)
                  days' prior written notice to Metro One. Each Mobile Carrier
                  may change its greeting or closing no more than once in any
                  thirty-day period. The greetings or closings provided by each
                  Mobile Carrier shall not include the trade names, trademarks
                  or brands of any competitor of such Mobile Carrier, and shall
                  not contain negative characterizations of such competitor's
                  service or business.

         l.       MULTIPLE REQUESTS. Subscribers shall be entitled to a maximum
                  of four (4) directory assistance requests per call.

         m.       MULTIPLE LISTINGS. When there is more than one address or

         c.       The numbers referenced in 5(a) and (b) above shall
                  collectively be referred to as the "EDA Numbers."


6.       FACILITIES AND EQUIPMENT

         a.       Metro One will maintain adequate and appropriate office
                  facilities, support facilities and other facilities to enable

                  purposes of performing the EDA Services for all Subscriber
                  calls. Metro One shall be responsible for establishing,
                  maintaining and paying for all other telecommunications
                  facilities associated with providing the EDA Services
                  described herein.

         c.       Mobile Carrier shall determine the quantities of circuit

         e.       Metro One and Mobile Carrier will each do such maintenance
                  testing and inspection of its own systems as may be necessary
                  to ensure the proper functioning of the interconnection(s).

         f.       If one Party's System interferes with, creates hazards over,
                  or impairs the service of the other Party's System, the Party
                  interfered with will, where practicable,

                  notify the other Party and advise it that a temporary
                  disconnection or discontinuance of the equipment or service
                  may be required. If the interference is not cured in a
                  reasonable time, the Party whose network is interfered with
                  may temporarily disconnect or discontinue service until the
                  interference is rectified. When prior notice is not
                  practicable, the Party interfered with may temporarily
                  disconnect or discontinue the interconnection or traffic
                  interchange without prior notice if such action is reasonable
                  under the circumstances; provided, however, that such Party
                  provides notice of disconnection as soon as is reasonably
                  practicable under the circumstances.

                  performance of the EDA Services at the rates set forth in
                  Exhibit E hereto  * * * upon commencement of EDA Services
                  after the trial period. In the event a credit is issued by
                  such Mobile Carrier to its Customer based on Metro One
                  connecting that Customer to an incorrect telephone number,
                  Metro One will have in place a mechanism to provide, and
                  shall provide a credit to such Mobile Carrier for such
                  calls. In the event that any Mobile Carrier in which AT&T
                  Wireless Services, Inc. owns fifty percent (50%) or less
                  equity interest ("Licensed Carrier") participates in this
                  Agreement, such Licensed Carrier shall be separately liable
                  for all payment for EDA Services provided to it hereunder
                  and no other Mobile Carrier shall be obligated to make any
                  payments on behalf of such Licensed Carrier.

         b.       Metro One shall provide each Mobile Carrier with its EDA call
                  count volume records in an agreed upon format on the 15th day
                  of each month for the previous month's calls. Mobile Carriers
                  shall be provided with a report as to total call volumes for
                  all Mobile Carriers during the same month ("Total Call
                  Volume"). The Total Call Volume shall be used, together with
                  the Market call volumes to determine the per call rates to be
                  charged each Mobile Carrier.

         c.       Metro One shall send each Mobile Carrier an invoice to the
                  billing contact listed for such Mobile Carrier in Exhibit A.
                  Each Mobile Carrier shall pay Metro One within forty-five (45)
                  days of receipt of such invoice. Any payments received after
                  such forty-five (45) days will incur interest in the amount of
                  1.50% a month.

                  With respect to any Licensed Carrier, such Licensed Carrier
                  shall pay Metro One within sixty (60) days of its receipt of
                  the invoice for such Licensed Carrier.

         d.       The compensation set forth in Exhibit B shall be the entire
                  compensation due Metro One from Mobile Carrier on account of
                  the EDA Services provided under this Agreement. Each Mobile
                  Carrier shall be separately liable for its invoice and shall
                  not be liable for the charges incurred by other Mobile
                  Carriers.

         e.       Mobile Carrier may deduct any disputed amounts from the
                  applicable Metro One invoice. Metro One agrees that disputed
                  amounts shall not be considered late payments and may be
                  withheld from pending payments until such time as the Parties
                  agree to the disposition of the disputed amount or until the
                  dispute is resolved pursuant to Section 24 below. Disputed
                  amounts will be paid, if owed, within 15 days of the
                  resolution of the dispute.

                  whatsoever.

         b.       Metro One shall indemnify, defend and hold Mobile Carrier

                  officers, directors, employees, representatives and agents of

         c.       Mobile Carrier shall defend, indemnify and hold Metro One
                  harmless from any Claim brought by a third party for which

                  willful misconduct of Mobile Carrier or its employees, agents
                  or contractors in connection with the performance of this
                  Agreement. Metro One shall promptly tender, and Mobile Carrier

                  settlement of any such Claim, providing that Metro One shall
                  not settle any Claim without the consent of Mobile Carrier,
                  which shall not be unreasonably withheld. Mobile Carrier also
                  shall reimburse Metro One for all attorneys' fees and expenses
                  incurred in defending

15-AGREEMENT FOR ENHANCED DIRECTORY ASSISTANCE SERVICES

                  against or investigating any such Claim, but Mobile Carrier
                  shall have no liability for such fees and expenses if it
                  accepts the defense of Metro One within ten (10) days of the
                  tender. Mobile Carrier's obligations under this Section shall
                  extend to Metro One, its parent, subsidiaries and affiliates,
                  and the officers, directors, employees, representatives and
                  agents of each of them.



16.      CONFIDENTIAL INFORMATION

         a.       With respect to all Confidential Information, the Party
                  receiving such information shall, unless otherwise agreed to
                  in writing by the Party furnishing such information, use
                  reasonable efforts to: a) neither use nor permit any use of
                  the Confidential Information for any purpose except in
                  connection with providing EDA Services pursuant to this
                  Agreement and except as may otherwise be agreed to in writing
                  by the other Party; b) restrict disclosure solely to those
                  employees, contractors or agents having a need to know; and c)
                  advise those employees receiving Confidential Information of
                  their obligations with respect thereto.

         b.       Confidential Information shall be deemed the property of the
                  furnishing Party for the purposes of this Agreement. The
                  receiving Party shall not reproduce or copy Confidential
                  Information except as required for the purposes stated herein
                  unless otherwise authorized by the furnishing Party in
                  writing. The receiving Party shall return to the furnishing
                  Party, or shall destroy, all records containing the
                  Confidential Information upon the termination of this
                  Agreement and upon written request by the furnishing Party.
                  The requirements of use and confidentiality set forth herein
                  shall survive for three (3) years after termination of this
                  Agreement.

         c.       Nothing contained in this Agreement shall be construed as
                  granting or conferring any rights by license or otherwise in
                  any information disclosed.

         d.       In the event either Party is requested or required (by oral
                  question, interrogatories, requests for information or
                  documents, subpoena, civil investigative demand or similar
                  process) to disclose Confidential Information of the other to
                  any lawfully constituted authority, it is agreed that the
                  Party requested or required to furnish the Confidential
                  Information will provide the other Party with timely notice in
                  order for that Party to seek a protective order or otherwise
                  object.

         e.       The Parties agree that it would be difficult to measure the
                  monetary damages that would be incurred by the other Party by
                  reason of the failure of the other Party to comply with the
                  terms of this paragraph. The Parties therefore agree that
                  either

16-AGREEMENT FOR ENHANCED DIRECTORY ASSISTANCE SERVICES
<PAGE>

                  Party may seek injunctive relief, which the Parties
                  agree is appropriate for enforcement of this paragraph.


17.      TERM

         * * * The term of this Agreement shall be automatically extended
         for additional period(s) of one (1) year each unless either Party
         notifies the other Party, in writing, at least ninety (90) days in
         advance of the end of the term then in effect, of that Party's
         intent to terminate the Agreement at the end of the term then in
         effect.


18.      TERMINATION

         a.       Any Mobile Carrier may terminate this Agreement immediately if
                  Metro One is in material breach of or default under this
                  Agreement by giving Metro One written notice of such
                  termination. The occurrence of any of the following shall
                  constitute a material breach of and default under this
                  Agreement by Metro One:

                  (1)      any failure by Metro One to perform any of its
                           material obligations in accordance with this
                           Agreement, where such failure continues for thirty
                           (30) days after written notice to Metro One or occurs
                           repeatedly after such written notice;

                  (2)      the filing by Metro One of a petition in bankruptcy
                           or the making of any general assignment for the
                           benefit of creditors;

                  (3)      any untruthfulness of any material information
                           provided by Metro One to Mobile Carrier relating to
                           this Agreement;

         b.       Metro One may terminate this Agreement immediately with
                  respect to a Mobile Carrier by providing such Mobile Carrier
                  with written notice of termination if such Mobile Carrier is
                  in material breach or default under this Agreement and such
                  breach or default continues for a period of thirty (30) days
                  after Metro One delivers written notice of such breach or
                  default to such Mobile Carrier; provided, however, that if
                  such breach or default is related to or arises out of a
                  disputed payment from such Mobile Carrier to Metro One, and
                  such disputed payment has been submitted for resolution under
                  Section 24 below, then Metro One shall have no right to
                  terminate this Agreement on the basis of such disputed
                  payment.

17-AGREEMENT FOR ENHANCED DIRECTORY ASSISTANCE SERVICES
<PAGE>

         c.       Either Party may terminate this Agreement if any circumstance
                  would render the continued performance of this Agreement by
                  either Party in violation of any applicable law, statute, rule
                  or regulation.

         d.       Upon termination or expiration of the term, in addition to any
                  other rights or remedies of Mobile Carrier, Metro One will:

                  (1)      cease to provide the EDA Services to Subscribers; and

                  (2)      deliver to Mobile Carrier a final invoice for amounts
                           payable under this Agreement;

         e.       Both Parties shall in addition upon termination or expiration
                  of the term:

                  (1)      promptly return to the other Party all materials
                           containing any Confidential Information of such
                           Party; and

                  (2)      cease all use, if any, of the other Party's Marks.


19.      LAWFULNESS

         This Agreement and the Parties' actions under this Agreement shall
         comply with all applicable federal, state, and local laws, rules,
         regulations, court orders, and governmental agency orders. If a court
         or a governmental agency with proper jurisdiction determines that this
         Agreement, or a provision of this Agreement, is unlawful, this
         Agreement, or that provision of this Agreement, shall terminate on the
         effective date of such court's determination. If a provision of this
         Agreement is so terminated, but the Parties legally, commercially, and
         practicably can continue this Agreement without the terminated
         provision, the remainder of this Agreement shall continue in effect.


20.      GOVERNMENT APPROVALS

         Each Party shall obtain all necessary regulatory approvals required of
         it and shall assist the other Party in obtaining all necessary
         regulatory approvals required of the other Party for the provision of
         EDA Services to Subscribers.

18-AGREEMENT FOR ENHANCED DIRECTORY ASSISTANCE SERVICES
<PAGE>

21.      ASSISTANCE

         Each Party will provide the other reasonable assistance in any matters
         affecting this Agreement before any governmental authority, trade
         association or other organization. Such assistance may include
         preparing and furnishing documents, providing advice, and providing
         qualified personnel to participate in hearings or other proceedings.


22.      FORCE MAJEURE

         Either Party shall be excused from performance if its performance is
         prevented by acts or events beyond the Party's reasonable control,
         including, but not limited to: severe weather and storms; earthquakes
         or other natural occurrences; strikes or other labor unrest; power
         failures; acts of legislative, judicial, executive or administrative
         authorities.


23.      ASSIGNMENT

         Neither Party may assign or transfer this Agreement or any of its
         obligations hereunder without the prior written consent of the other,
         which consent will not be unreasonably withheld.


24.      SERVICE TESTING

         Metro One may negotiate with each Mobile Carrier for the provision of a
         wireless telephone, wireless access line of landline access line to be
         used to test the quality of Metro One's services for such Mobile
         Carrier. Nothing in this Agreement shall require Metro One and any
         Mobile Carrier to come to an agreement on this provisioning.


25.      SURVIVAL OF OBLIGATIONS

         The obligations set forth in Sections 12 ("Trademarks") and 16
         ("Confidential Information") and in this Section 25 hereof will survive
         the termination or expiration of this Agreement, in addition to any
         other provisions that, by their content, are intended to survive the
         performance, termination, or cancellation of this Agreement.

26.      DISPUTE RESOLUTION

         a.       The Parties desire to resolve disputes arising out of this
                  Agreement without litigation. Accordingly, except for an
                  action seeking a temporary restraining order or an injunction
                  related to the purposes of this Agreement, or an action to
                  compel compliance with this dispute resolution process, the
                  Parties agree to use the following dispute resolution
                  procedure as their sole remedy with respect to any controversy
                  or claim arising out of or relating to this Agreement or its
                  breach. The existence of a dispute, which is being resolved
                  under the procedures set forth herein, shall not be grounds
                  for termination of the agreement, and both parties shall
                  continue to perform under this Agreement while such dispute is
                  being resolved.

                  (1)      At the written request of a Party to resolve a
                           dispute, each Party will appoint a knowledgeable,
                           responsible representative to meet and negotiate in
                           good faith to resolve any dispute arising under this
                           Agreement. The Parties intend that these negotiations
                           shall be conducted by non-lawyer, business
                           representatives. The location, format, frequency,
                           duration and conclusion of these discussions shall be
                           left to the discretion of the representatives. Upon
                           reaching agreement, the representatives may utilize
                           other alternative dispute resolution procedures, such
                           as mediation, to assist in the negotiations.
                           Discussion and correspondence among the
                           representatives for purposes of these negotiations
                           shall be treated as confidential information
                           developed for purposes of settlement, exempt from
                           discovery and production, and shall not be admissible
                           in the arbitration discussed below, or any
                           litigation, without the concurrence of both Parties.
                           Documents identified in or provided with such
                           communications, which are not prepared for purposes
                           of negotiations, are not so exempted and may, if
                           otherwise admissible, be admitted in evidence in the
                           arbitration of lawsuit.

                  (2)      If the negotiations do not resolve the dispute within
                           sixty (60) days of the initial written request, the
                           dispute shall be submitted to binding arbitration by
                           a single arbitrator pursuant to the Commercial
                           Arbitration Rules of the American Arbitration
                           Association. A Party may demand such arbitration in
                           accordance with the procedures set out in those
                           rules. Discovery shall be controlled by the
                           arbitrator and shall be permitted to the extent set
                           out in this subsection. Each Party may submit in
                           writing to a Party, and that Party shall so respond,
                           to a maximum of any combination of thirty-five (35)
                           (none of which may have subparts) of the following:
                           interrogatories, requests for production of
                           documents, and requests for admission. Each Party is
                           also entitled to take the oral deposition of up to
                           three individuals

20-AGREEMENT FOR ENHANCED DIRECTORY ASSISTANCE SERVICES
<PAGE>

                           of the other Party. Additional discovery may be
                           permitted upon mutual agreement of the Parties.

                  (3)      The arbitration hearing shall be commenced within
                           ninety (90) days of the demand for arbitration. The
                           arbitration shall be held in Seattle, Washington, or
                           such other location as is agreed upon among the
                           arbitrator and the Parties. The arbitrator shall
                           control the schedule so as to process the matter
                           expeditiously. The Parties may submit written briefs
                           of no more than 25 pages in length, double spaced, 10
                           pitch, with left and right hand margins of at least
                           one inch. The arbitrator shall rule on the dispute by
                           issuing a written opinion within thirty (30) days of
                           the close of hearings. The times specified in this
                           subsection may be extended upon a showing of good
                           cause. Judgment upon the award rendered by the
                           arbitrator may be entered in any court having
                           jurisdiction.

                  (4)      Each Party shall bear its own costs of these
                           procedures. A Party seeking discovery shall reimburse
                           the responding Party for the responding Party's
                           copying costs of reproducing the documents. The
                           Parties shall equally split the fees of the
                           arbitration and the arbitrator.


27.      ENTIRE AGREEMENT

         This Agreement constitutes the entire agreement between the Parties
         related to the subject matter hereof, and supersedes any and all prior
         negotiations, representations, correspondence, understandings and
         agreements with respect to the subject matter hereof. No amendment,
         alteration, or modification of any of the terms of this Agreement will
         be effective unless in a writing signed by both Parties.

         Metro One, their respective successors and permitted assigns any rights
         or remedies under or by reason of this Agreement.


29.      WAIVER

         The failure of either Party to enforce at any time any provision hereof
         shall not be construed to be a waiver of such provision or the right
         thereafter to enforce each and

         every provision. No waiver by either Party to this Agreement, either
         express or implied, or any breach of any term, condition or obligation
         of this Agreement shall be construed as a waiver of any subsequent
         breach of that term, condition or obligation, or of any other term,
         condition or obligation of this Agreement.
