            Claim against Crosswave Communications Inc. ("Crosswave")
            ---------------------------------------------------------

     In May 2002, to assist Crosswave in securing loan financing, Internet
Initiative Japan ("IIJ") entered into a JPY 5.0 billion Cash Deficiency Support
Agreement (the "CDS Agreement") with Crosswave and four Japanese commercial
banks. The CDS Agreement is a commitment by IIJ to cover cash deficiency up to
JPY 5.0 billion in case of shortage in the principal and interest payment funds
or acceleration in connection with a Syndicated Loan Agreement for an aggregate
sum of JPY 20 billion. The banks are entitled to claim the JPY 5.0 billion
amount directly from IIJ. Since IIJ provided JPY 5.0 billion to the banks as the
security deposit, the claim of the banks was set off against such deposit.

     The security deposit of JPY 5.0 billion which IIJ provided to the banks
making the syndicated loan to Crosswave under the CDS Agreement was acquired by
the banks upon Crosswave's filing of a petition for commencement of corporate
reorganization proceedings. Accordingly, IIJ now holds a claim for
indemnification against Crosswave in the amount of JPY 5.0 billion, and plans to
file this JPY 5.0 billion claim with the reorganization administrator of
Crosswave as a reorganization claim. However, if IIJ receives interest and
principal in connection with this claim under the reorganization plan or
otherwise, IIJ will have to pay such interest and principal either entirely or
partly to the banks.
