ITEM 2.           DISPOSITION OF ASSETS

         On July 15, 2002, iBasis, Inc. ("iBasis") completed the sale of
substantially all of the assets of its wholly owned subsidiary, iBasis Speech
Solutions, Inc. ("ISS"), to Convergys Customer Management Group Inc. (the
"Purchaser"), a wholly owned subsidiary of Convergys Corporation ("Convergys"),
for $17 million in cash delivered upon closing on July 15, 2002, an additional
$1.5 million placed in escrow to secure certain indemnification obligations
assumed by iBasis, and up to $16 million in earn-out payments that may be
awarded upon the achievement of certain milestones by the business of ISS. The
earn-out period will conclude on December 31, 2003.

         The assets of ISS sold to Purchaser included, but were not limited to:
accounts receivable; equipment, fittings, furniture and leasehold improvements;
customer lists; all rights under leases, contracts and other agreements or
instruments; intellectual property; goodwill; and business records and other
documents.

         ISS developed and hosted advanced Interactive Voice Response (IVR) and
Advanced Speech Recognition (ASR) solutions for large carrier and enterprise
customers. Based in Reston, Va., ISS had approximately 40 customers.

         In connection with the sale, iBasis expects to record a loss of
approximately $61.5 million from discontinued operations in the second quarter
2002. For the second quarter 2002 and all prior quarters, iBasis financial
results will report the Speech Solutions business in a single line item as
discontinued operations.

                           not include Disclosure Schedules or Exhibits. IBasis
                           will furnish a copy of any such omitted schedule or
