7.   PERFORMANCE STANDARDS

     7.1  GENERAL

     Incumbent shall perform the Services at least to the level and degree of
     accuracy, quality, completeness, timeliness, responsiveness and efficiency
     as set forth in the Critical Service Levels in Schedule B.  At all times,
     Incumbent's level of performance shall meet Performance Standards as
     identified in this Maintenance Agreement and its Schedules and shall be
     consistent with industry standards.

     7.2  FAILURE TO PERFORM

          7.2.1     Incumbent recognizes that its failure (i) to meet any
          Critical Service Level, (ii) correct any Outage, or (iii) remedy any
          other problem that threatens to adversely impact the operation of the
          System may have a material adverse impact on the business and
          operations of Pathnet.  Accordingly, in the event that Incumbent
          repeatedly (i) fails to meet any Critical Service Level, (ii) correct
          any Outage, or (iii) remedy any other problem that threatens to
          adversely impact the operation of the System, for reasons other than
          the wrongful actions of Pathnet or circumstances that constitute Force
          Majeure under this Maintenance Agreement, Pathnet, at its sole
          discretion, may elect (i) to not renew this Maintenance Agreement or
          (ii) to supplement the provision of Services by Incumbent by
          appointing a new Maintenance provider in accordance with Section 9.3.

          7.2.2     In the event of any problem affecting the operation of the
          System (including, without limitation, the events listed in Section
          7.2.1), Incumbent shall (i) investigate and report to Pathnet the
          causes of such problem or Outage; (ii) advise Pathnet of the status of
          remedial efforts being undertaken with respect to such problems; (iii)
          correct the problem as soon as practical and restore the System's
          operation to the Critical Service Levels; and (iv) take appropriate
          preventive measures so that the problem does not recur.

          7.2.3     Pathnet or its designee shall have the right, subject to the
          terms of this Maintenance Agreement and the FPM Agreement, to
          reasonable, full and immediate access to any and all affected
          Facilities to repair the Equipment or System and to supplement the
          Services if operations fall below the Performance Standards; provided
          such supplemental Maintenance will not degrade or interfere with the
          operation of the Initial System or Incumbent's use of its Facilities
          for its current or future operations, provided also that such future
          operations do not interfere with the 


                                          11


     System pursuant to Section 5.4.2 of the FPM Agreement.  Upon Pathnet's
     prior notification, Incumbent shall reasonably cooperate with Pathnet or
     its designee, including providing any escorts necessary for Pathnet to
     supplement the Services.

          7.2.4     In the event Pathnet either (i) does not renew this
          Maintenance Agreement or (ii) supplements the Services, Pathnet will
          arrange for an independent Maintenance provider to provide any or all
          of the Services hereunder, including any or all of the Services
          relating to maintenance of the Initial System; provided Incumbent
          shall also have the right to continue to maintain the Initial System
          at Incumbent's sole expense, so long as such maintenance shall not
          impact Pathnet's ability to maintain the System.

          Service Levels and the Monthly Service Charges paid to Incumbent. 
          Pathnet and Incumbent shall mutually agree to make adjustments to the
          Critical Service Levels, as appropriate, to reflect (i) improved

          necessary to measure and to report operational performance of the
          System against the applicable Critical Service Levels.  Such
          measurement and monitoring tools and equipment shall permit reporting
          at a level of detail sufficient to verify compliance with Critical
          Service Levels and shall be reviewable by Pathnet upon reasonable
          notice.  Upon reasonable request by Pathnet, Incumbent shall provide
          Pathnet with information and access to such tools and procedures for
          purposes of verification.

          shall have the right to reasonably audit any and all such reports
          maintained by Incumbent.  These reports shall be available to Pathnet
          for its reasonable inspection at Incumbent's Facilities and a copy of
          the compilation of these reports is to be forwarded to Pathnet on a
          quarterly basis.  Such reports shall be considered Proprietary
          Information of Incumbent and protected in accordance with Section 12.2
          of the FPM Agreement; provided Pathnet shall have the right to
          disclose such reports to any equity owner, debt provider, lender, or
          other creditor; any potential customer or purchaser of capacity, any
          potential party to a merger or acquisition, any service provider under
          this Maintenance Agreement; or any other attorneys, consultants or
          financial advisors.

          8.2.2     Pathnet shall have the right to reasonably inspect the
          Facilities and Equipment at any time upon reasonable notice to
          Incumbent and to supplement the Maintenance Services during Pathnet's
          inspection; provided Pathnet complies with any and all Incumbent
          security procedures and the provisions of the FPM Agreement.


9.   TERMINATION

     9.1  TERMINATION FOR CAUSE

          9.1.1     In the event that Incumbent:  (i) commits a material breach
          of this Maintenance Agreement, which breach is not cured within thirty
          (30) days after notice of breach from Pathnet to Incumbent or (ii)
          commits numerous breaches of its duties or obligations which
          collectively constitute a material breach of this Maintenance
          Agreement (and Incumbent has been previously notified of such
          breaches), Pathnet may, by giving reasonable written notice to
          Incumbent, terminate this Maintenance Agreement, in whole or in part,
          as of the date specified in the notice of termination.  If Pathnet
          chooses to terminate this Maintenance Agreement in part, the charges
          payable to Incumbent under this Maintenance Agreement will be
          equitably adjusted to reflect those services that are terminated.


                                          13


          9.1.2     In the event that Pathnet fails:  (i) to pay Incumbent
          undisputed charges due under the Maintenance Agreement totaling at
          least Two Thousand Dollars ($2,000) (excluding any reimbursement of
          Pass-Through Expenses) and fails to make such payment within thirty
          (30) days of notice from Incumbent of the failure to make such payment
          or (ii) otherwise fails to fulfill its obligations, Incumbent may, by
          giving written reasonable notice to Pathnet, terminate this
          Maintenance Agreement as of the date specified in the notice of
          termination. 

     9.2  TERMINATION FOR CONVENIENCE

     Incumbent may terminate this Maintenance Agreement for convenience and
     without cause at any time by giving Pathnet at least ninety (90) days'
     prior written notice before the end of the Term of this Maintenance
     Agreement indicating that Incumbent will not renew this Maintenance
     Agreement; provided, however, that Pathnet, its Affiliates, agents or
     Subcontractors may, at Pathnet's sole discretion, supplement or perform the
     Services set forth in this Maintenance Agreement.

     9.3  TERMINATION OR EXPIRATION ASSISTANCE

     In the event (i) Incumbent terminates this Maintenance Agreement for
     convenience; (ii) Pathnet does not renew this Maintenance Agreement because
     of Incumbent's failure to perform, or (iii) the FPM Agreement expires,
     Pathnet shall propose and Incumbent shall approve, which approval shall not
     be unreasonably withheld, a third-party, independent Maintenance provider,
     at least forty-five (45) days before termination or expiration of the FPM
     Agreement to provide the Services at Incumbent's Facilities.  Such
     independent Maintenance provider shall provide the Services and assume the
     obligations of Incumbent hereunder for any successive terms coterminous
     with the remaining term of the FPM Agreement, unless such provider is
     replaced by Pathnet before the expiration of the term of this Maintenance
     Agreement or any extension thereof.  In the event either Party terminates
     this Maintenance Agreement for cause, Pathnet shall provide a third-party
     Maintenance provider to perform the Services, and Incumbent shall
     reasonably cooperate with such provider.  Upon expiration or termination of
     this Maintenance Agreement, Pathnet shall, for the remaining term of the
     FPM Agreement, perform or cause to be performed the services required to
     meet Pathnet's operational requirements (including Spare Parts and
     equipment repair assistance on the Initial System) and shall have the right
     to full and reasonable access to all Facilities in accordance with the
     terms of the FPM Agreement in order to supplement or perform the Services
     in accordance with the Performance Standards.

     13.3 INDEMNIFICATION PROCEDURES

     With respect to any third party claims, the following procedures shall
     apply:

     13.3.1    NOTICE.  Promptly after receipt by an entity entitled to
               indemnification under Section 13.1 or Section 13.2 of notice of
               the commencement or threatened commencement of any civil,
               criminal, administrative or investigative action or proceeding
               involving a claim in respect of which the indemnitee will seek 


                                          18


               indemnification pursuant to any such Section, the indemnitee
               shall notify the indemnitor of such claim in writing.  No failure
               to so notify an indemnitor shall relieve it of its obligations
               under this Maintenance Agreement except to the extent that it can
               demonstrate damages attributable to such failure.  Within fifteen
               (15) days following receipt of written notice from the indemnitee
               relating to any claim, but no later than ten (10) days before the
               date on which any response to a complaint or summons is due, the
               indemnitor shall notify the indemnitee in writing if the
               indemnitor elects to assume control of the defense and settlement
               of that claim (a "NOTICE OF ELECTION").

        13.3.2 PROCEDURE FOLLOWING NOTICE OF ELECTION.  If the indemnitor
               delivers a Notice of Election relating to any claim within the
               required notice period, the indemnitor shall be entitled to have
               sole control over the defense and settlement of such claim;
               provided that, (i) the indemnitee shall be entitled to
               participate in the defense of such claim and to employ counsel at
               its own expense to assist in the handling of such claim, and (ii)
               the indemnitor shall obtain the prior written approval of the
               indemnitee before entering into any settlement of such claim or
               ceasing to defend against such claim.  After the indemnitor has
               delivered a Notice of Election relating to any claim in
               accordance with Section 13.3.1 above, the indemnitor shall not be
               liable to the indemnitee for any legal expenses incurred by the
               indemnitee in connection with the defense of that claim.  In
               addition, the indemnitor shall not be required to indemnify the
               indemnitee for any amount paid or payable by the indemnitee in
               the settlement of any claim for which the indemnitor has
               delivered a timely Notice of Election if such amount was agreed
               to without the written consent of the indemnitor.

        13.3.3 PROCEDURE WHERE NO NOTICE OF ELECTION IS DELIVERED.  If the
               indemnitor does not deliver a Notice of Election relating to any
               claim within the required notice period, the indemnitee shall
               have the right to defend the claim in such manner as it may deem
               appropriate, at the cost and expense of the indemnitor.  The
               indemnitor shall promptly reimburse the indemnitee for all such
               costs and expenses.

     13.4 SUBROGATION

     In the event that an indemnitor shall be obligated to indemnify an
     indemnitee pursuant to Section 13.1 or Section 13.2, the indemnitor shall,
     upon payment of such indemnity in full, 


                                          19


     be subrogated to all rights of the indemnitee with respect to the claims to
     which such indemnification  relates.

                    NEGLIGENCE AND STRICT LIABILITY IN TORT), SHALL A PARTY BE
                    LIABLE TO THE OTHER PARTY FOR LOST PROFITS, INDIRECT OR
                    CONSEQUENTIAL, EXEMPLARY, PUNITIVE OR SPECIAL DAMAGES,
                    ARISING OUT OF OR IN CONJUNCTION WITH THIS MAINTENANCE
                    AGREEMENT EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE
                    POSSIBILITY OF SUCH DAMAGES IN ADVANCE.

          14.2.2    The limitations set forth in Section 14.2.1 shall not apply
                    with respect to (i) damages occasioned by the willful
                    misconduct or gross negligence of a Party and (ii) damages
                    occasioned as a result of the indemnification obligations
                    set forth in Section 13 if and to the extent any third party
                    shall be awarded such damages explicitly excluded in Section
                    14.2.1.

     14.3 FORCE MAJEURE

          14.3.1    No Party shall be liable for any default or delay in the
                    performance of its obligations under this Maintenance
                    Agreement (i) if and to the extent such default or delay is
                    caused, directly or indirectly, by a Force Majeure event,
                    (ii) provided the non-performing Party is without fault in
                    causing such default or delay, and such default or delay
                    could not have been prevented by reasonable precautions and
                    can not reasonably be circumvented by the non-


                                          20


                    performing Party through the use of alternate sources, work
                    around plans or other means.

          14.3.2    In such event, the non-performing Party shall be excused
                    from further performance or observance of the obligation(s)
                    so affected for as long as such circumstances prevail and
                    such Party continues to use its best efforts to recommence
                    performance or observance whenever and to whatever extent
                    possible without delay.  Any Party so delayed in its
                    performance shall immediately notify the Party to whom
                    performance is due by telephone (to be confirmed in writing
                    within two (2) days of the inception of such delay) and
                    describe at a reasonable level of detail the circumstances
                    causing such delay.


15.  DISPUTE RESOLUTION

     15.1 ARBITRATION; RESOLUTION OF DISPUTES

     Any and all disputes and controversies between Incumbent and Pathnet
     concerning the negotiation, interpretation, performance, breach or
     termination of this Maintenance Agreement (each a "Dispute") shall be
     subject to resolution by the procedure set forth in Section 17.2 of the FPM
     Agreement which is hereby incorporated herein.

16.  MISCELLANEOUS

     16.1 NOTICE PROVISION

     Notice shall be served and deemed received in accordance with the
     provisions of Section 18.1 of the FPM Agreement which is hereby
     incorporated herein.

     16.2 BINDING NATURE; ENTIRE AGREEMENT

     Pathnet and Incumbent acknowledge (i) that each has read and understands
     the terms and conditions of this Maintenance Agreement and agrees to be
     bound by such terms and conditions, (ii) that this Maintenance Agreement is
     the complete and conclusive statement of the agreement between the Parties,
     and (iii) that this Maintenance Agreement sets forth the entire agreement
     and understanding between the Parties relating to the subject matter
     hereof.  All understandings and agreements, oral and written, heretofore
     made between Incumbent and Pathnet relating to the subject matter hereof
     are merged in this Maintenance 


                                          21


     Agreement which alone, fully and completely expresses their agreement on
     the subject matter of maintenance service to be provided by Incumbent.  The
     provisions of this Maintenance Agreement are separate and apart from the
     provisions of the FPM Agreement and may not in any way affect either
     Party's obligations with regard to the FPM Agreement.

     16.3 AMENDMENT

     No modification of, additions to or waiver of this Maintenance Agreement
     shall be binding upon Incumbent and Pathnet unless such modification is in
     writing and signed by an authorized representative of each Party.

     16.4 SEVERABILITY

     If any term or provision of this Maintenance Agreement shall to any extent
     be held by a court or other tribunal to be invalid, void or unenforceable,
     then that term or provision shall be inoperative and void insofar as it is
     in conflict with law, but the remaining terms and provisions of this
     Maintenance Agreement shall nevertheless continue in full force and effect
     and the rights and obligations of the Parties shall be deemed to be
     restated to reflect newly as possible the original intentions of the
     Parties in accordance with applicable law.

     16.5 HEADINGS

     Section and paragraph headings used in this Maintenance Agreement are for
     reference and convenience only and are not to be deemed or construed to be
     part of this Maintenance Agreement.

     16.6 CONSENTS AND APPROVAL

     Except where expressly provided as being in the sole discretion of a Party,
     where agreement, approval, acceptance, consent, or similar action by either
     Party is required under this Maintenance Agreement, such action shall not
     be unreasonably delayed or withheld.  An approval or consent given by a
     Party under this Maintenance Agreement shall not relieve the other Party
     from responsibility for complying with the requirements of this Maintenance
     Agreement, nor shall it be construed as a waiver of any rights under this
     Maintenance Agreement, except as and to the extent otherwise expressly
     provided in such approval or consent.

     16.7 COMPLIANCE WITH LAWS AND REGULATIONS



                                          22


     Each Party shall perform its obligations in a manner that complies with the
     applicable Federal, state and local laws, regulations, ordinances and codes
     (including identifying and procuring required permits, certificates,
     approvals and inspections).  If a charge of non-compliance by either Party
     with any such laws, regulations, ordinances or codes occurs, the Party
     charged with such non-compliance shall promptly notify the other Party of
     such charges in writing.

     16.8 GOVERNING LAW

     This Maintenance Agreement and the rights and duties of the Parties shall
     be governed and interpreted in accordance with the laws of the State of
     Indiana, other than the choice of law rules thereof.

     16.9 BINDING NATURE AND ASSIGNMENT

     This Maintenance Agreement shall be binding on the Parties hereto and their
     respective successors and assigns.  Neither Party may or shall have the
     power to assign this Maintenance Agreement without the prior written
     consent of the other, except that either Party may assign its rights and
     obligations under this Maintenance Agreement without the approval of the
     other Party to an entity which acquires all or substantially all of the
     assets of that Party to any subsidiary or Affiliate or successor in a
     merger or acquisition of that Party; provided that in no event shall any
     such assignment relieve that Party of its obligations under this
     Maintenance Agreement.

     16.10  WAIVER

     Failure or delay on the part of Incumbent or Pathnet to exercise any right,
     power or privilege under this Maintenance Agreement shall not constitute a
     waiver of any right power or privilege of this Maintenance Agreement.

     16.11  TIME TO SUE

     No action shall be brought for any breach of this Maintenance Agreement
     more than two (2) years after the accrual of such cause of action, except
     where applicable law provides for a shorter limitation period, in which
     event that period should apply.


                                          23


     16.12  SURVIVAL

     Any provision of this Maintenance Agreement which contemplates performance
     or observance subsequent to any termination or expiration of this
     Maintenance Agreement shall survive any termination or expiration of this
     Maintenance Agreement and continue in full force and effect.

     16.13  COVENANT OF GOOD FAITH

     Each Party agrees that in its respective dealings with the other Party
     under or in connection with this Maintenance Agreement, it shall act in
     good faith.

     IN WITNESS WHEREOF, the Parties hereto have executed this Maintenance
Agreement, or caused it to be executed by a duly authorized officer, as of the
date first written above.
