      pay all accrued and unpaid legal fees of counsel to Arranger and all fees
      and expenses estimated to be incurred in connection with amending the UCC

Party hereby acknowledges that it has reviewed the terms and provisions of the
Credit Agreement and this Waiver. Each Loan Party hereby confirms that each
Credit Support Document to which it is a party or otherwise bound and all
Collateral encumbered thereby will continue to guaranty or secure, as the case
may be, to the fullest extent possible the payment and performance of all
"Guarantied Obligations" and "Secured Obligations" as the case may be (in each
case as such terms are defined in the applicable Credit Support Document),
including without limitation the payment and performance of all such "Guarantied
Obligations" or "Secured Obligations," as the case may be, in respect of the
Obligations of Borrowers now or hereafter existing under or in respect of the
Credit Agreement. Each Credit Support Party acknowledges and agrees that any of
the Credit Support Documents to which it is a party or otherwise bound shall
continue in full force and effect and that all of its obligations thereunder
shall be valid and enforceable and shall not be impaired or limited by the
execution or effectiveness of this Waiver. Each Credit Support Party (other than

            SECTION 6.  AGREEMENT OF LENDERS

                  Lenders hereby agree that in the event the Borrowers fail to

respect thereto. Such delay or failure by Agents or Lenders to exercise during
such time any of their other rights and

                                       5
<PAGE>   6

remedies, shall not impair any power, right or privilege granted to Agents or
Lenders in the Credit Agreement or any other Loan Document or by law available

of the exercise of remedies as a result of any other Event of Default under the
Credit Agreement.

            SECTION 7.  MISCELLANEOUS

      effect and are hereby ratified and confirmed.

               (ii) The execution, delivery and performance of this Waiver

      Documents.

            B. HEADINGS. Section and subsection headings in this Waiver are

<PAGE>   2

SECTION 1.  AGREEMENT OF LENDERS

            Lenders hereby agree to forebear, until July 10, 2000, exercising
any remedies under the Loan Documents as a result of the Events of Default
caused by Borrowers failure to be in compliance with the covenants set forth in
subsection 6.6A(ii) or subsection 6.6A(iii) of the Credit Agreement for the
Fiscal Quarters ended March 31, 2000 and June 30, 2000, as long as no other
holder of Indebtedness of any Loan Party has accelerated such Indebtedness or is
otherwise exercising any remedies with respect thereto. Such delay or failure by
Agents or Lenders to exercise during such time any of their other rights and
remedies, shall not impair any power, right or privilege granted to Agents or
Lenders in the Credit Agreement or any other Loan Document or by law available
to them or be construed to be a waiver of or acquiescence in any Event of
Default under the Credit Agreement or any other Loan Document or a forbearance
of the exercise of remedies as a result of any other Event of Default under the
Credit Agreement.

SECTION 2.  WAIVERS

            Subject to the terms and conditions set forth herein and in reliance
on the representations and warranties of Borrowers herein contained:

            (a)   Lenders hereby waive compliance with the provisions of
      subsection 2.4B(iii)(a) of the Credit Agreement to the extent, and only to
      the extent, that such provisions would not permit Borrowers to reinvest
      the Net Asset Sale Proceeds received from the Designated Assets in lieu of
      making a mandatory prepayment because the Events of Default subject to the
      forbearance agreement of Lenders have occurred and are continuing,
      provided that the Borrowers reinvest such Net Asset Sale Proceeds in
      Telecommunications Assets in the manner described in subsection
      2.4B(iii)(a). In connection with the reinvestment of such Net Asset Sale
      Proceeds from the Designated Assets, Lenders hereby waive compliance with
      the certification provisions of subsection 2.4B(iii)(a)(1), but not (2),
      to the extent, and only to the extent, that Borrowers deliver to
      Administrative Agent an Officers' Certificate in the form attached hereto
      as Exhibit B.

            (b)   Lenders hereby consent to the release of the Liens under the
      Collateral Documents on the Designated Assets, such release to be
      effective upon the sale thereof in accordance with subsection 6.8. In
      connection with such release of Liens under the Collateral Documents on
      the Designated Assets, Lenders hereby waive compliance with the notice and
      certification provisions of subsection 8.6 of the Credit Agreement
      relating to the release of Liens in connection with permitted Asset Sales
      to the extent, and only to the extent, that Borrowers deliver to
      Administrative Agent an Officers' Certificate in the form attached hereto
      as Exhibit B.

SECTION 3.  LIMITATION OF WAIVERS

            Without limiting the generality of the provisions of subsection 9.6
of the Credit Agreement, the waiver set forth above shall be limited precisely
as written and relates solely to the noncompliance by Company with the
provisions of subsections 2.4B(iii)(a) and 8.6 of the Credit Agreement in the
manner and to the extent described above, and nothing in this Waiver shall be
deemed to:

                                       2
<PAGE>   3

            (a)   constitute a waiver of compliance by Company with respect to
      (i) subsections 2.4B(iii)(a) and 8.6 of the Credit Agreement in any other
      instance or (ii) any other term, provision or condition of the Credit
      Agreement or any other instrument or agreement referred to therein; or

            (b)   prejudice any right or remedy that Agents or any Lender may
      now have (except to the extent such right or remedy was based upon
      existing defaults that will not exist after giving effect to this Waiver)
      or may have in the future under or in connection with the Credit Agreement
      or any other instrument or agreement referred to therein.

            Except as expressly set forth in this Waiver, the terms, provisions
 and conditions of the Credit Agreement and the other Loan Documents shall
 remain in full force and effect and in all other respects are hereby ratified
 and confirmed.

SECTION 4.  ADDITIONAL AGREEMENT OF BORROWERS

            In consideration of Lenders entering into this Waiver, Borrowers
hereby agree to provide Administrative Agent and Lenders as soon as available,
and in any event within 30 days after the end of each month (other than the last
month of each Fiscal Quarter), the consolidated balance sheets of Company and
its Subsidiaries as at the end of such month and the related consolidated
statements of income and cash flows of Company and its Subsidiaries for such
month and for the period from the beginning of the then current Fiscal Year to
the end of such month, setting forth in each case in comparative form the
corresponding figures for the corresponding periods of the previous Fiscal Year
and the corresponding figures from the Financial Plan for the current Fiscal
Year, to the extent prepared on a monthly basis, all in reasonable detail and
certified by the chief financial officer of Company that they fairly present, in
all material respects, the financial condition of Company and its Subsidiaries
as at the dates indicated and the results of their operations and their cash
flows for the periods indicated, subject to changes resulting from audit and
normal quarterly and year-end adjustments. Failure of Borrowers to comply with
the agreement set forth in this Section 4 shall constitute an Event of Default
under the Credit Agreement.
