                NORTH CAROLINA UTILITIES COMMISSION ISSUES ORDER
                 DENYING PAYMENT TO US LEC FOR METACOMM TRAFFIC


         CHARLOTTE, NC (April 3, 2000)-US LEC Corp.(Nasdaq: CLEC), a leading
provider of integrated telecommunications services, today issued the following
statement. As US LEC Corp. has previously reported, BellSouth Telecommunications
Inc. ("BellSouth") began a proceeding in September 1998 before the North
Carolina Utilities Commission ("NCUC") seeking to be relieved of any obligation
under its interconnection agreements with the Company to pay reciprocal
compensation for traffic related to the network operated by Metacomm, LLC
("Metacomm"), a customer of both US LEC and BellSouth. After the close of the
securities markets on March 31, 2000, the NCUC issued an order in this
proceeding that relieves BellSouth from paying reciprocal compensation to US LEC
for any minutes of use attributable to Metacomm network traffic and requires US
LEC to cease billing BellSouth reciprocal compensation for minutes of use
attributable to the Metacomm or any similar network (the "March 31 Order").

         The March 31 Order does not affect in any way the NCUC's order of
February 1998 requiring BellSouth to pay reciprocal compensation to the Company
for Internet service provider ("ISP") traffic in North Carolina. It relates
solely to traffic on Metacomm's "always-on" network in North Carolina (the only
state in which Metacomm operates and the only state in which US LEC provides
service to such a network). As previously announced, the Company received a
payment of $11.2 million from BellSouth on July 16, 1999, representing a portion
of



the amounts due to the Company for non-Metacomm reciprocal compensation for
ISP traffic in North Carolina. The March 31 Order also has no effect on US LEC's
operations in any other state or its pending claims against BellSouth for
reciprocal compensation for ISP traffic in Florida, Georgia and Tennessee.

         Aaron D. Cowell, Jr., the Company's President, said: "While we are
extremely disappointed with the unexpected outcome of this decision, including
the failure of the NCUC to require BellSouth to pay reciprocal compensation to
us for usage of the Metacomm network by its customers, US LEC will comply fully
with the March 31 Order. We believe it is in the best interests of the Company
and all our constituencies, including our employees, customers and stockholders,
to move forward and focus US LEC's resources on the continued expansion of our
core business. It is important to stress that this decision will not affect our
ongoing business strategy, expansion plans or operating environment."

         As reported in the Company's Form 10-K for the year ended December 31,
1999 (the "10-K"), filed with the Securities and Exchange Commission on March
30, 2000, the Company recorded approximately $50 million and $98 million of
reciprocal compensation revenue related to Metacomm network traffic, before
allowances of $12 million and $27 million, for the fiscal year ended 1998 and
1999, respectively.

         The Company estimates that the March 31 Order will result in a pre-tax,
nonrecurring charge of approximately $55 million (which will be reduced by
income taxes of approximately $20 million) in the first quarter 2000. The
charge, which is noncash, is composed of the write-off of approximately $153
million in receivables related to reciprocal compensation revenue offset by
previously established reserves of $39 million and a reduction of $59 million in
commissions owed to Metacomm. Also, the Company had previously recorded $21
million of

                                       2


advances to Metacomm and a $15 million receivable for services provided to
Metacomm. Richard T. Aab, Chairman of US LEC, indirectly controls Metacomm, and
has assured the Company that these amounts will be paid.

         The noncash charge in the first quarter 2000 is not expected to affect
the Company's growth plans for its core business. At March 31, 2000, the Company
had approximately $8 million in cash and $58 million of borrowing availability
under its senior credit facility. In addition, both Bain Capital Inc. ("Bain")
and Thomas H. Lee Partners, L.P. ("THL") have confirmed that their affiliates
intend to finalize the transaction for their investments of $200 million in a
new series of the Company's convertible preferred stock and an option to invest
up to an additional $100 million in another series of convertible preferred
stock. A letter of intent for this transaction was originally announced by the
Company on February 25, 2000. With the Company's borrowing availability under
its senior credit facility and the amounts to be invested by affiliates of Bain
and THL, the Company believes that it has the necessary capital resources to
implement its business strategy over the next several years.

         Michael K. Robinson, the Company's Chief Financial Officer, commented:
"US LEC has continued to execute and demonstrate strong sequential growth in our
core business, exclusive of reciprocal compensation. For the year ended December
31, 1999, gross revenue minus reciprocal compensation and related revenue grew
by approximately 125% compared with 1998. As previously announced, the Company
has not included in its business plan any Metacomm related revenue for 2000 and
beyond. We expect that our core local business and data services will continue
to drive the Company's growth in 2000, and we believe that US LEC is well
positioned for future success as a full service telecommunications provider."
