NOW, THEREFORE, for and in consideration of the mutual covenants and agreements
set forth below, and for other valuable consideration received, the parties
hereto agree as follows:

1.   TERM

     Subject to the other provisions contained in this Agreement, the initial
     term of this Agreement shall be for a period of twelve months commencing on
     January 1, 2004 and continuing until December 31, 2004; provided, however,
     that the term of this Agreement shall automatically be extended for
     additional periods of twelve months each unless either party hereto gives
     to the other party hereto, at least 30 days prior to the expiration of the
     then existing term hereof, written notice of the termination, with or
     without cause, of this Agreement as of the end of the then existing term
     hereof.

2.   SERVICES

     During the term hereof, IIJA shall exercise its best efforts to provide the
     assistance and services specified on Exhibit I hereto, as the same may from
     time to time be amended with the written consent of both parties hereto.

3.   EXAMINATION OF BOOKS AND RECORDS

                                       1
<PAGE>

     IIJ shall have the right at its expense to examine the books and records of
     IIJA in connection with this Agreement during normal business hours at
     IIJA's offices on reasonable notice.

4.   SERVICE FEES

     During the term hereof, in consideration of the services to be provided by
     IIJA under this Agreement, IIJ shall pay to IIJA a monthly Service Fee to
     be calculated as follows:

     4.1 Assignment and Allocation of Costs. IIJA shall assign and/or allocate
     all SG&A Costs and all Costs of Connection between IIJA's Backbone Division
     and IIJA's Own Division in the following manner.

       a.     For the initial four month period of this Agreement, SG&A costs
              shall be allocated in accordance with pre-determined
              classifications of SG&A expenses: first, any salary, benefits and
              overhead costs that are directly related to only one of the
              Divisions shall be assigned to that Division in their entirety;
              second, any remaining personnel costs shall be allocated on the
              basis of the weighted aggregate average percentage of time spent
              by all allocable employees with respect to each Division's
              activities; third, any remaining business expenses such as travel
              and remaining overhead costs shall be allocated based on the
              percentages used for personnel costs for each Division; fourth,
              outsourcing expenses for professional services shall be allocated
              based on the estimated benefit that each Division shall enjoy from
              such services, or equally, if such benefits are not reasonably
              subject to estimation.

       b.     For the initial four month period of this Agreement, IIJA shall,
              first, assign to each Division any Costs of Connection that are
              directly related to only one of the Divisions and, second,
              allocate any remaining Costs of Connection based on the relative
              amount of aggregate bandwidth committed to customers of both IIJ
              and IIJA as of October 2003. For subsequent years, the allocation
              percentage for the following year will be determined once a year
              based on the relative amount of aggregate bandwidth committed to
              customers of both IIJ and IIJA as of the end of October of the
              current year.

       c.     Beginning in May 2004 and continuing each February, May, August
              and November subsequently, IIJA shall review and update the
              amounts of costs allocable to each Division, based on actual costs
              incurred during the immediately previous three month calculation
              periods from January through March, April through June, July
              through September, and October through December, respectively. The
              amounts of the allocable costs as updated as above, shall take
              effect as of May, August, November and the following February,
              respectively, and be used for determining the Monthly Service Fee
              as set forth in Section 4.2 for the current three month period.

     4.2 Monthly Service Fee.

                                       2
<PAGE>

       a.     One-third of the actual Costs of Connection for each calculation
              period that are assigned and allocated to the Backbone Division
              shall be charged as part of the Service Fee on a monthly basis for
              the current three month period.

       b.     For the first four months of this Agreement, the SG&A costs to be
              assigned and allocated shall be based on the average monthly
              amount actually incurred by IIJA's Backbone Division during the
              prior three month period of October through December 2003.
              Thereafter, the SG&A costs to be assigned and allocated shall be
              one-third of the actual SG&A costs of IIJA's Backbone Division for
              the relevant three month calculation period. The SG&A costs for
              each month that are assigned and allocated to the Backbone
              Division shall be multiplied by one (1) plus the Mark-Up
              Application Rate in effect for that year and the result shall be
              charged as part of the Service Fee.

     4.3 Mark-up Application Rate. The Mark-up Application Rate for the first
     year of this Agreement shall be eight (8) percent, although such rate can
     be subject to change under the following circumstances. In the event that
     IIJ and IIJA agree that the Mark-up Application Rate no longer results in
     an arm's length mark-up from a U.S. and Japanese transfer pricing
     perspective, such Mark-up Application Rate shall be adjusted to so result
     in an arm's length mark-up. Such adjusted Mark-up Application Rate shall be
     effective as of the date agreed to by the parties, which can be retroactive
     to an earlier point in the current calendar year.

      4.4 True-up of Service Fee. Each January beginning with January 2005, IIJA
      shall undertake the following true-up procedure:

       a.     IIJA shall determine whether IIJA's Backbone Division's ratio of
              gross profit over operating expenses for the preceding calendar
              year falls within the interquartile range of IIJA's comparable
              companies' ratio of gross profit over operating expenses for the
              second preceding year or satisfies some other methodology used for
              U.S. transfer pricing purposes. If IIJA's Backbone Division's
              ratio of gross profit over operating expenses falls within the
              interquartile range of IIJA's comparable companies' ratio of gross
              profit over operating expenses for the second preceding year or
              satisfies some other methodology to be used for U.S. transfer
              pricing purposes for the preceding year, no true-up shall be
              required.

       b.     If, on the other hand, IIJA's Backbone Division's ratio of gross
              profit over operating expenses as defined above does not fall
              within the interquartile range of IIJA's comparable companies'
              ratio of gross profit over operating expenses for the second
              preceding year or satisfy some other methodology used for U.S.
              transfer pricing purposes, IIJA shall determine the amount of
              true-up required.

              i.   If IIJA's Backbone Division's ratio falls below the
                   interquartile range, IIJA shall calculate the additional
                   Mark-up Application Rate necessary for its ratio of gross
                   profit over operating expense for the preceding calendar

                                       3
<PAGE>

                   year to fall within the interquartile range of IIJA's
                   comparable companies' ratio of gross profit over operating
                   expenses for the second preceding year. This difference in
                   the Mark-up Application Rate shall be multiplied by actual
                   SG&A expenses for the preceding year to determine the true-up
                   amount by which the Service Fee for the preceding year needs
                   to be increased.

              ii.  If IIJA's Backbone Division's ratio falls above the
                   interquartile range, IIJA shall calculate the reduction in
                   the Mark-up Application Rate necessary for its ratio of gross
                   profit over operating expense for the preceding calendar year
                   to fall within the interquartile range of IIJA's comparable
                   companies' ratio of gross profit over operating expenses for
                   the second preceding year. This difference in the Mark-up
                   Application Rate shall be multiplied by actual SG&A expenses
                   for the preceding year to determine the true-up amount by
                   which the Service Fee for the preceding year needs to be
                   reduced.

       c.     IIJA shall record for statutory accounting purposes for its most
              recently ended calendar year, an increase or decrease in Service
              Fee income and accounts receivable or payable, respectively, in
              the amount calculated in b. above.

       d.     IIJ shall record for statutory accounting purposes for its current
              fiscal year, an increase or decrease in Service Fee expense and
              accounts payable or receivable, respectively, in the amount
              calculated in b. above.

       e.     Notwithstanding the requirements of this subparagraph regarding
              calculation of a true-up amount, the parties must also agree that
              the true-up amount to be recorded by IIJ and IIJA appears
              reasonable from a Japanese transfer pricing perspective.

      4.5 Invoicing and Payment. IIJA shall furnish to IIJ within fifteen (15)
      days after the end of each month an invoice for the Service Fee for that
      month determined in accordance with subsections 4.2 and 4.4 of this
      paragraph. IIJA shall furnish to IIJ a detailed explanation of the
      computation of any monthly Service Fee upon IIJ's request. IIJ shall pay
      the Service Fee specified in each invoice within sixty (60) days after
      receipt of such invoice by telegraphic transfer. Payments shall be made in
      U.S. dollars.

5.   RELATIONSHIP OF THE PARTIES

     5.1 The relationship between IIJA and IIJ under this Agreement shall be
     that of service provider and client, respectively.

     5.2 IIJA shall not contract in the name of IIJ and IIJA shall not represent
     or hold itself out as the agent of IIJ nor do any act or thing which might
     result in any third party believing that IIJA has authority to contract or
     enter into any commitment on behalf of or in the name of IIJ.

     event of any breach or default by the other party of any of the terms or
     conditions of this Agreement, either party may immediately terminate this
     Agreement by giving written notice thereof to the other party. All amounts
     due each of the parties hereto, respectively, shall thereupon become due
     and immediately payable.

7.   RISK AND LIABILITY

     professional and workmanlike manner. Except for the foregoing, IIJA makes
     no other warranties or representations as to the Services rendered, and

11.  IMPOSSIBILITY OF PERFORMANCE

If, for any reason outside the control of IIJA, performance by IIJA of the
services or any of them becomes impractical for any reason after IIJA has taken
all reasonable steps to rectify the situation, then the parties will together
