                        FIRST AMENDMENT TO LOAN AGREEMENT

         WHEREAS, the Borrower, the Lender and the Administrative Agent are
parties to that certain Loan Agreement dated as of May 14, 1999 (as heretofore
amended, modified, supplemented and restated, the "LOAN AGREEMENT"); and

         WHEREAS, the Borrower has requested, and the Lender has agreed, subject
to the conditions and on the terms set forth in this Amendment, to make certain
amendments to the Loan Agreement, as provided in this Amendment;

         NOW, THEREFORE, in consideration of the premises set forth above, the
covenants and agreements set forth in this Amendment, and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto hereby agree that all capitalized terms used in
this Amendment shall have the meanings ascribed thereto in the Loan Agreement,
and further hereby agree as follows:

         1.       AMENDMENT TO ARTICLE 1. Article 1 of the Loan Agreement,
DEFINITIONS, is hereby amended by deleting the existing definitions of "CLEC NET
PROCEEDS" and "EBITDA" in their entirety and substituting in lieu thereof the
following:

                  "'CLEC NET PROCEEDS' shall mean, with respect to any sale,
         lease, transfer or other disposition of all or any part of the CLEC
         Business by the Parent or any of its Subsidiaries, the difference
         between (1) the difference between (a) the aggregate amount of cash
         received by the Parent or any of its Subsidiaries for such assets
         (including, without limitation, any payments received for
         non-competition covenants, consulting or management fees in connection
         with such sale, and any portion of the amount received evidenced by a
         promissory note or other evidence of Indebtedness issued by the
         purchaser), MINUS (b) the sum of (i) amounts reserved, if any, for
         taxes payable with respect to any such sale (after application
         (assuming application first to such reserves) of any available losses,

         costs properly attributable to such transaction and payable by the
         Parent or any of its Subsidiaries (other than to an Affiliate) in
         connection with such sale, lease, transfer or

         other disposition of assets, including, without limitation,
         commissions and severance and other payments to employees due to
         termination of employment in an aggregate amount not to exceed
         $1,500,000.00, and (iii) until actually received by the Parent or
         any of its Subsidiaries, any portion of the amount received held in
         escrow or evidenced by a promissory note or other evidence of
         Indebtedness issued by a purchaser or non-compete, consulting or
         management agreement or covenant or otherwise for which compensation
         is paid over time, MINUS (2) amounts permitted to be paid pursuant
         to that certain Letter Agreement dated as of October 14, 1999 by the
         Lender in favor of Saville Systems, Inc., which amounts may not
         exceed $2,336,797.00 in the aggregate. Upon receipt by the Parent or
         any of its Subsidiaries of (A) amounts referred to in item (b)(iii)
         of the preceding sentence, or (B) if there shall occur any reduction
         in the tax reserves referred to in item (b)(i) of the preceding
         sentence resulting in a payment to the Parent or its Subsidiaries,
         such amounts shall then be deemed to be CLEC Net Proceeds.'"

                  "'EBITDA' shall mean, with respect to the Borrower and its
         Subsidiaries, on a consolidated basis, the sum of (a) Net Income for
         any period (after eliminating any extraordinary gains and losses),
         PLUS, (b) to the extent deducted in determining such Net Income, the
         sum of (i) depreciation and amortization, (ii) Interest Expense, (iii)
         income taxes paid and (iv) all other non-cash items, in each case, for
         such period, PLUS, (c) for each period ending on or prior to the
         earlier to occur of (i) June 30, 2000 and (ii) the Maturity Date,
         $3,000,000.00."

COPIES OF OTHER REPORTS, is hereby amended by adding new subsection (e) as
follows:

                  "(e)   Within fifteen (15) days after the last day of each

         consecutive calendar month period ending on such date), which report
         shall (i) be certified by the chief financial officer of the Borrower
         to have been prepared in accordance with GAAP and (ii) include
         calculations demonstrating the Borrower's compliance with Sections 7.8,

         connection with the operation of the CLEC Business in an
         aggregate amount not to exceed $2,500,000.00 per calendar month
         (which amount shall be exclusive of payments made to satisfy the
         obligation of the Parent to Northern Telecom in connection with the
         purchase of certain switch equipment which amount shall not exceed
         $3,000,000.00) or $15,000,000.00 prior to the Maturity Date, in each
         case, so long as (x) each such loan is evidenced by a promissory
         note made by such Person in favor of the Borrower in form and
         substance satisfactory to the Administrative Agent and (y) each such
         promissory note is assigned as Collateral and delivered to the

         (b)      AMENDMENT TO SECTION 7.8. Section 7.8 of the Loan Agreement,

         calendar quarter, and (b) at the time of any Advance hereunder (after
         giving effect to such Advance), the Borrower shall not permit its
         Leverage Ratio to exceed 5.00 to 1.00."

         (c)      Article 7 of the Loan Agreement, NEGATIVE COVENANTS, is hereby
further amended by adding new Section 7.14, MINIMUM EDITDA, as follows:

agreed to herein shall not constitute a modification of the Loan Agreement or
any of the other Loan Documents, or a course of dealing with the
Administrative Agent and the Lenders at variance with the Loan Agreement or
any of the other Loan Documents, such as to require further notice by the
Administrative Agent or the Lenders to require strict compliance with the

         6.       LOAN DOCUMENTS. This Amendment shall be deemed to be a Loan

         7.       COUNTERPARTS. This Amendment may be executed in any number of

hereof in that jurisdiction or affecting the validity or enforceability of such
provision in any other jurisdiction.
