     "and (v) any misuse or misappropriation by Indemnitor of web enabled call
     monitoring recordings. Sprint Spectrum shall indemnify Metro One for claims
     arising from web enabled call recordings, if such claims are not the result
     of Metro One's failure to comply with Sprint Spectrum's requirements and
     procedures for such recordings, as described in a valid Work Order. Metro
     One shall indemnify Sprint Spectrum for claims arising from the recording
     of calls which result from the actions of Metro One, its employees, agents,
     representatives, or contractors."

7.   Section 15, Termination, is amended by adding the following:

     "h. TERMINATION FOR CONVENIENCE. At any time, but no later than March 31,
     2000, Sprint Spectrum may notify Metro One of the month Sprint Spectrum
     will terminate this Agreement, in whole or in part, taking into
     consideration Section 16.g, at any time, with no liability other than the
     fees set forth in Exhibit 15, attached hereto. Sprint Spectrum will provide
     Metro One a wind-down transition period plan which details the timeframe 
     and market-by-market plan to re-route the Calls. The termination effective 
     date will be as determined by Sprint Spectrum during the wind-down 
     transition period. This termination for convenience option may not be 
     exercised prior to March 1, 2000.

     If Sprint Spectrum terminates this Agreement for convenience as provided in
     this Section 15.h., Sprint Spectrum agrees to pay Metro One a termination
     fee in an amount equal to the amounts set forth in Exhibit 15, attached
     hereto. The amount of the termination fee will be based upon the effective
     date of the termination for convenience."

8.   In Section 16.a., Affiliate Transactions, delete the Section in its
     entirety and replace it with the following:

     "This Agreement is entered into by Sprint Spectrum on its own behalf and
     for the benefit of all Sprint Spectrum embedded and independent affiliated
     entities (each a "Sprint Spectrum Affiliate"). An embedded Affiliate means
     any entity who is authorized to sell digital wireless products or services
     under the Sprint PCS brand name or any other brand name(s) subsequently
     primarily used by Sprint Spectrum to market its digital wireless products
     and services and Sprint Spectrum is Metro One's day-to-day contact and
     responsible party for accounts receivable. An independent Affiliate means:
     a) any entity in which Sprint Spectrum holds or controls an equity or
     similar interest; b) any entity which holds or controls an equity or
     similar interest in Sprint Spectrum; c) any subsidiary, and any
     corporation, partnership, limited liability company, limited liability
     partnership, joint venture or other entity controlling, controlled by or
     under common control with Sprint Spectrum, directly or indirectly by or
     through one or more intermediaries; d) Tele-Communications, Inc., Comcast
     Corporation, Cox Communications, Inc. or Sprint Corporation; e) SprintCom,
     Inc.; or f) any entity that is authorized to sell digital wireless products
     or services under the Sprint PCS brand name or any other brand name(s)
     subsequently primarily used by Sprint Spectrum to market its digital
     wireless products and services and Sprint Spectrum is not Metro One's
     day-to-day contact and responsible party for accounts receivable.

     All references to Sprint Spectrum refer equally to each Sprint Spectrum
     Affiliate executing a Work Request with terms in accordance with this
     Agreement. No Sprint Spectrum Affiliate is authorized or allowed to modify
     any policies, processes, procedures, scripts, etc. that Metro One and
     Sprint Spectrum have agreed to without the prior written consent of Sprint
     Spectrum. Any embedded or independent Affiliate not executing a Work
     Request under this Agreement is considered an Alternate Channel for
     purposes of this Agreement. No commitment is made by Sprint Spectrum or any
     Sprint Spectrum Affiliate, or any liability accepted, except as set forth
     in

     a properly signed Work Request. All communications and invoices must be
     directed to the Sprint Spectrum Affiliate issuing the Work Request under
     the instructions contained in the Work Request. Services performed on
     behalf of any Sprint Spectrum Affiliate will be invoiced to and collected
     from that Sprint Spectrum Affiliate only. Only the Sprint Spectrum
     Affiliate issuing a specific Work Request under this Agreement will incur
     any obligation or liability for any claim which may arise from or relate to
     that Work Request.

9.   In the second line of Section 16.b., Affiliate Rights, after the word
     "Agreement", insert "with the prior written consent of Sprint Spectrum and
     Metro One, which consent will not be unreasonably withheld."

10.  Exhibit 13 in its entirety and all references to Exhibit 13 contained in
     the Agreement are deleted.

11.  Add the following new subsection to Section 16:

     "g.  ACQUISITIONS: If Sprint Spectrum acquires a controlling interest in
          any entity which has Services provided to it by Metro One, Sprint
          Spectrum may, in its sole discretion, terminate the contract for
          Services between Metro One and such entity, without liability, and the
          acquired entity will be provided Services pursuant to the terms and
          conditions of this Agreement for the greater of a) the remaining term
          of this Agreement; or b) the initial term remaining on the acquired
          entity's agreement, which shall be limited to no more than five (5)
          years."

12.  In Section 2.n., EDA Services Numbers, insert the following as the second
     and third sentence:

     "At Sprint Spectrum's sole discretion, Sprint Spectrum may or may not route
     such calls to Metro One if such calls are associated with an "Alternate
     Channel". The term Alternate Channel means a distribution channel for
     Sprint Spectrum products and services which may be branded under a
     different name, co-branded, or marketed in such a way that Sprint Spectrum
     does not solely own the end user relationship or any entity to whom Sprint
     Spectrum is required by law, regulation or contract to provide products or
     services involving products or services to be provided pursuant to this
     Agreement."

13.  Exhibits 1, 2, and 3 are deleted in their entirety and replaced by the
     attachments hereto and Exhibit 15 is added.

14.  Section 2.r. is deleted in its entirety and replaced with the following:

     "YEAR 2000 WARRANTY. Metro One warrants that the hardware, software and
     firmware used to provide Enhanced Directory Assistance under this Agreement
     which contain or depend upon a date processing function (the "Systems")
     will be "Year 2000 Compliance" no later than ***, which means the
     functions, calculations, and other computing processes of the System
     (collectively "Processes") perform and otherwise process, perform date
     arithmetic, display, print or pass date/time data in a consistent manner,
     regardless of the date in time on which the Processes are actually
     performed or the dates used in such data, whether on, during or after
     January 1, 2000 and whether or not the date/time data is affected by leap
     years. To the extent the System is intended to be used in combination with
     other Sprint Spectrum software, hardware and/or firmware, the System will
     properly exchange date/time data with such software, hardware and/or
     firmware to the extent the Sprint Spectrum software, hardware and firmware,
     correctly processes date/time data input. The System will accept and
     respond to two-digit year-date input, correcting or supplementing as
     necessary, and store, print, display or pass date/time data in a manner
     that is unambiguous as to

     century. No date/time data will cause the System to perform an abnormally
     ending routine or function within the Processes or generate incorrect
     values or invalid results.

     Metro One warrants that the System will be been tested by Metro One to
     determine whether the System is Year 2000 Compliant. Upon the written
     request of Sprint Spectrum, Metro One will deliver the test objectives and
     results of such tests.

     If determined by Metro One or Sprint Spectrum that the System is not Year
     2000 Compliant, Metro One will, at its expense, within thirty (30) days
     after notice of the non-compliance, either (1) immediately correct or
     modify the System such that it is Year 2000 Compliant; or (2) replace the
     System with a System that is functionally equivalent to the non-compliant
     System and is Year 2000 Compliant. If neither of these options are
     available, Sprint Spectrum may terminate this Agreement without any
     liability.

Except as expressly modified by this Amendment, the terms and conditions of the
Agreement remain in full force and effect.

IN WITNESS WHEREOF, the parties have caused this Amendment Number 1 to be
executed and represent and warrant that the signatory whose signature appears
