                              CLOSING CERTIFICATES

                  The Secretary of State of Illinois has not issued a
Certificate of Good Standing for US Xchange of Illinois, L.L.C. because the
records of the Secretary of State of Illinois do not reflect that US Xchange of
Illinois, L.L.C. has filed its 1998 limited liability company annual report with
the Illinois Secretary of State by its due date (December 1, 1998). We have been
informed by US Xchange of Illinois, L.L.C. that it filed the requisite annual
report on or about November 18, 1998, but that the office of the Illinois
Secretary of State has not as yet reflected its receipt of this report on its
records. Under Illinois law (805 ILCS 180/50-15), a limited liability company
which is not in good standing is potentially liable for fines in the amount of
$100, plus $50 for each month in which the company is not in good standing, as
well as limitations on the ability of the company to make filings with the
Illinois Secretary of State.
