                  4.       Promptly furnish to lender such other information and
                           reports concerning the Borrower's business, Property
                           and financial condition as are provided to Borrower's
                           owners or as Lender shall request, and permit Lender
                           to inspect, confirm, and copy Borrower's books and
                           records at any time during Borrower's normal business
                           hours.

         B.       NOTICE OF ADVERSE EVENTS. Promptly notify Lender in writing of
                  any litigation, governmental proceeding, default or any other
                  occurrence that may have a material adverse effect on
                  Borrower's business, Property or financial condition.

         C.       MAINTAIN BUSINESS EXISTENCE AND OPERATIONS. Do all things
                  necessary to keep in full force and effect Borrower's
                  corporate existence and maintain its present business status.
                  Borrower shall not change its corporate existence, nor sell or
                  merge Borrower's business, in whole or in part, to or with any
                  other Person, or issue or transfer any membership interest in
                  Borrower to any other person without the prior written consent
                  of Lender.

         D.       INSURANCE. Maintain adequate fire and extended risk coverage,
                  business interruption, workers compensation, public liability
                  and such other insurance coverages as may be required by law
                  or as may be required by Lender. All insurance policies shall
                  be in such amounts, upon such terms, and be in a form
                  acceptable to lender, and shall be carried with insurers
                  acceptable to Lender. Borrower shall, upon Lender's request,
                  provide evidence satisfactory to Lender that all such the
                  policies are in full force and effect, and that Lender is
                  named as an additional insured and a loss payee under such
                  policies, and that the insurer is required to provide Lender
                  thirty (30) days' advance written notice of any cancellation
                  or expiration of coverage. If Borrower fails to maintain
                  insurance as provided in this Agreement, such failure shall be
                  an Event of Default and Lender may obtain such insurance on
                  Borrower's behalf but shall have no obligation to do so; all
                  amounts so expended by Lender shall be added to the
                  Indebtedness or shall be payable on demand, at Lender's
                  option.

         E.       PAYMENT OF TAXES. Promptly pay all taxes, levies and
                  assessments due to all local, State and Federal agencies.
                  Except to the extent that Borrower has established a cash
                  reserve therefore and is actively pursuing a tax appeal, any
                  failure by Borrower to promptly pay any taxes, levies, and
                  assessments due shall be an Event of Default.

         F.       EMPLOYEE BENEFIT PLANS.

                  1.       At no time shall Borrower allow any event to occur or
                           condition to exist with respect to any employee
                           benefit plan to subject to ERISA which might
                           constitute grounds for a termination of the plan or
                           for the appointment of a trustee to administer any
                           such plan.

                  2.       At no time shall Borrower allow any employee benefit
                           plan subject to ERISA to be the subject of voluntary
                           or involuntary termination proceedings from which
                           there may result a liability of the Borrower to the
                           PBGC which, in the opinion of the Lender, will have a
                           material adverse effect upon the business,
                           properties, or financial condition of Borrower.

         G.       USE OF PROCEEDS; PURPOSE OF LOANS. Borrower shall use the
                  proceeds of the Loan(s) only for the acquisition of network
                  facilities and general business capital expenditures and for
                  normal operating expenses in the conduct of the Borrower's
                  telecommunications business.

         H.       MAINTENANCE OF RECORDS; CHANGE IN PLACE OF BUSINESS OF NAME.
                  Borrower shall keep all of its books and records at the
                  address set forth in this Agreement, and shall give the Lender
                  prompt written notice of any change in its principal place of
                  business, in the location of Borrower's books and records, in
                  Borrower's name, and any change in the location of the
                  Collateral.

         I.       WORKERS COMPENSATION INSURANCE. Borrower shall at all times
                  during the term of this Agreement and until the Indebtedness
                  shall have been fully repaid, maintain workers' compensation
                  insurance as required by law unless Borrower is qualified and
                  duly authorized by law to self-insure with respect to its
                  workers' compensation liability and is not otherwise
                  prohibited by this Agreement from doing so.

         A.       SECURITY INTERESTS. Borrower named in this Agreement has
                  granted or agrees to grant to Lender on the same date as this
                  Agreement a security interest in all of Borrower's assets,

                                       5

   6

                  payable to Borrower by any taxing authority, as more
                  particularly defined by the Michigan Uniform Commercial Code
                  as collateral security for the Loan and repayment of the
                  Indebtedness.

         B.       DOCUMENTS. The security interests granted to Lender shall be
                  evidenced by a written security agreement signed by Borrower
                  in form and substance acceptable to Lender, and shall be
                  performed by the filing of a UCC financing statement, in form
                  and substance acceptable to Lender, signed by Borrower, and
                  filed with the appropriate filing offices of the State of
                  Michigan.

         C.       SUBORDINATION. Lender hereby agrees to subordinate its right
                  to repayment of the Indebtedness, as well as its lien in the
                  Collateral, in favor of any secured credit facilities
                  outstanding on the date of this Agreement. Upon Borrower's
                  request, Lender will execute and deliver any document or
                  instrument reasonably necessary to effectuate this
                  subordination.

VI.      EVENTS OF DEFAULT.

         The occurrence of any of the following events shall constitute an Event
         of Default under this Agreement:

         A.       FAILURE TO PAY AMOUNTS DUE. If any principal and interest due
                  and owing under the Note, or any other Indebtedness due and
                  owing to Lender is not paid when due. Borrower will have
                  thirty (30) days after the due date to remedy the default
                  before Lender shall be entitled to pursue its remedies under
                  this Agreement.

         B.       MISREPRESENTATION; FALSE FINANCIAL INFORMATION. If any
                  warranty or representation of the Borrower in connection with
                  or contained in this Agreement, or if any Financial Statements
                  now or hereafter furnished to the Lender by or on behalf of
                  the Borrower, are false or misleading in any material respect.

         C.       BREACH OF COVENANTS OR AGREEMENTS. If the Borrower shall fail
                  to perform any of its obligations and covenants under, or
                  shall fail to comply with any of the provisions of this
                  Agreement or any other agreement with Lender, including but
                  not limited to the Related Documents.

         D.       OTHER DEFAULTS. Any indebtedness of Borrower to any person
                  other than Lender is declared to be due and payable prior to
                  the stated maturity thereof, or is otherwise declared to be in
                  default.

         E.       JUDGMENTS; ATTACHMENTS; TAX LIENS. If there shall be entered
                  against Borrower any judgment which materially affects
                  Borrower's business, properties or financial condition, or if
                  any tax lien, levy, attachment, garnishment, execution or
                  similar writ shall be issued against the Collateral or which
                  materially affects Borrower's business, Property or financial
                  condition,


                                       6

                  unbonded, or undismissed for a period of thirty (30) days
                  after the entry thereof.

         F.       BUSINESS MERGER SUSPENSION, BANKRUPTCY. If Borrower sells or
                  merges the assets of, or any ownership interests in Borrower's

                  Lender, and without demand or notice of any kind, be declared

                  right, remedy, power or privilege. No delay or failure of
                  Lender at any time to demand strict adherence to the terms of
                  this Agreement shall be deemed to constitute a course of
                  conduct inconsistent with the Lender's right at any time
                  before or after any Event of Default, to demand strict
                  adherence to the terms of this Agreement or the Related
