      the sites for the Facilities as set forth in Schedule B, which sites shall
      be approved in writing by the LLC and Pathnet for inclusion in the
      development of Segment B, within twelve (12) months after the Effective
      Date (such approval by Pathnet not to be unreasonably withheld, provided
      that if the economic cost to Pathnet materially outweighs the economic
      benefit to Pathnet as the result of the use of such site, such
      circumstance shall be deemed a reasonable basis for withholding such
      consent), or (ii) Incumbent, the LLC and/or Pathnet fall to obtain the
      permits, approvals and licences (including frequency coordination)
      necessary to begin construction on Segment B within fifteen (15) months

                                     -11-


            3.2.2 Non Performance. If Pathnet does not deliver any Segment of
      the System in accordance with the Specifications within eighteen (18)
      months after Incumbent and/or the LLC delivers (i) the requisite permits,
      approvals and licenses required to develop the sites of the Facilities on
      such Segment or (ii) sites of the Facilities in suitable form (including
      delivering electric service to the sites) to construct the System for such
      Segment, whichever is later, unless such failure of Pathnet to deliver any
      Segment of the System in accordance with the Specifications results from
      Incumbent unreasonably withholding any approvals required of Incumbent
      with respect to installation of the System, then the LLC shall have the
      right to terminate this Agreement only as to such Segment.

SECTION 4. CONSIDERATION

      4.1 Consideration Paid to Pathnet. In consideration for the services to be
performed and the obligations assumed by Pathnet pursuant to this Agreement, the
LLC shall grant to Pathnet (i) the right to use the Facilities, pursuant to
Section 6, and the Equipment, and (ii)       [***]

                                           as set forth in the Channel Plan
pursuant to the terms of the Pathnet IRU Agreement.

SECTION 5. ALLOCATION OF COSTS

      5.1 LLC Costs.

            5.1.1 LLC Items. Subject to the LLC Payment Cap set forth in Section
      5.1.3, LLC shall pay for the services, functions, materials and other
      items listed in Section 1 of Schedule C and Exhibit C-1 of Schedule C
      (collectively, the "LLC Items") in the manner set forth in Section 5.1.5
      and as set forth in the LLC Agreement.

            5.1.2 Estimated Cost of LLC Items. On the Effective Date, the total
      estimated cost of the LLC Items with respect to Segment A 
                                       [***]
                   (the "Segment A LLC Estimated Costs") and with respect to
      Segment B is [***]

                       (the "Segment B LLC Estimated Costs"). Subject to the
      LLC Payment Cap, the costs of such items and the LLC Estimated Costs are
      estimates and may be subject to increases or decreases, provided that the
      cost of Pathnet engineering and project management shall be no more than
      the estimated cost for these items as shown in Schedule C.

            5.1.3 LLC Payment Cap. Subject to Section 8.3, LLC shall pay an
      amount not to exceed             [***]                (the "LLC Payment
      Cap") in the aggregate for the performance and completion of the LLC Items
      on Segments A and B. Payment of any LLC Item shall be approved by Pathnet
      prior to the payment thereof if and to the extent such payment is subject
      to the LLC Payment Cap. The cost of LLC Items shall be accrued in
      accordance with generally accepted accounting principles. Pathnet shall
      pay for all amounts incurred over the LLC Payment Cap in the completion
      and performance of the LLC Items. As soon as LLC is aware that LLC will
      pay an amount in excess of the LLC Payment Cap,


                                      -12-


      LLC shall notify Pathnet to that effect. In the event the Parties elect
      not to construct Segment B pursuant to Section 3.1.5, the LLC Payment Cap
      shall be adjusted to be twenty percent (20%) over the Segment A LLC
      Estimated Costs.

            5.1.4 Division of Costs Savings. In the event the costs of
      completion of the LLC Items for Segment A and Segment B are less than the
      LLC Estimated Costs, Pathnet shall deliver to the LLC an invoice setting
      forth the differential between the total costs to complete and perform the
      LLC Items and the LLC Estimated Costs. Within thirty (30) days of receipt
      of such invoice from Pathnet, the LLC shall pay or disburse to Pathnet
      thirty-five percent (35%) of such differential. Pathnet shall be liable
      for any invoices received after distribution of the costs savings is made
      pursuant to this Section 5.1.4.

            5.1.5 Payment by LLC. Subject to the LLC Payment Cap set forth in
      Section 5.1.3, the LLC shall promptly pay, or the LLC shall cause
      Incumbent to promptly pay pursuant to the LLC Agreement, for the LLC Items
      for which it is liable upon receipt of a purchase order, invoice or other
      bill from Pathnet or from an equipment vendor or service provider
      (pursuant to any Pathnet requested retention), provided Pathnet has
      approved (which approval shall not be unreasonably withheld) such purchase
      order, invoice or bill before any payment is made by the LLC.

      5.2 Pathnet Costs.

            5.2.1 Pathnet Items. Pathnet shall pay for services, functions,
      materials and other items listed in Section 2 of Schedule C, and Exhibit
      C-2 of Schedule C (the "Pathnet Items").

            5.2.2 Estimated Cost of Pathnet Items. On the Effective Date, the
      total estimated cost of the Pathnet Items with respect to Segment A is
                                     [***]
                  (the "Segment A Pathnet Estimated Costs"), and with respect to
      Segment B is                       [***]                              (the
      "Segment B Pathnet Estimated Costs").

            5.2.3 No Cap on Pathnet Items. Subject to Section 3.1.5 regarding
      Segment B, Pathnet shall pay for all amounts incurred in completing the
      Pathnet Items whether or not the cost of completing such items is less
      than, equal to or exceeds the Segment A and Segment B Pathnet Estimated
      Costs.

SECTION 6. INDEFEASIBLE RIGHT TO USE.

      6.1 Indefeasible Right to Use. The LLC hereby grants to Pathnet for the
term of this Agreement a non-exclusive and indefeasible right to use each of the
Facilities at such sites set forth on Schedule B, and Equipment, including,
without limitation, the Initial System, in each case to the extent necessary for
the performance of Pathnet's rights and obligations under this Agreement
including the right to create and sell capacity on the System including any
Capacity Expansion on the System.


                                        -13-


      6.2 Use of Facilities.

            6.2.1 Peaceful Enjoyment, Use and Access. Subject to the terms of
      Incumbent's site leases Pathnet shall have the right to the non-exclusive
      peaceful use and enjoyment of the Facilities during the term of this
      Agreement as required for the performance of Pathnet's rights and
      obligations under this Agreement, which rights shall include, but not be
      limited to (i) the right to use the Facilities and Equipment and (ii) upon
      the reasonable request by Pathnet, the right to full and free access to
      the Facilities and related equipment; provided, however, any such access
      granted by the LLC to Pathnet shall be subject to the reasonable security,
      health and safety and other regulatory, procedural and policy requirements
      implemented by Incumbent, and provided to Pathnet from time to time,
      provided Pathnet shall have twenty (20) days after receipt of any such
      policy or procedure to comply therewith. In the event the terms of
      Incumbent's site leases materially and adversely affect Pathnet's ability
      to perform its obligations under this Agreement, the LLC shall, or the LLC
      shall cause Incumbent to, (x) use best efforts to amend any such lease or
      otherwise renegotiate any limitations thereto or (y) use commercially
      reasonable efforts to lease or acquire an alternative Facility location in
      order that Pathnet may perform hereunder. If and to the extent the LLC is
      not able, or the LLC is not able to cause Incumbent to (i) amend or
      otherwise re-negotiate the site leases or (ii) provide an alternative
      Facility available for the installation and operation of the System,
      Pathnet shall have, as its sole and exclusive remedy, the unilateral right
      but no obligation to terminate this Agreement as to any Segment without
      any further recourse against LLC or Incumbent hereunder.

            6.2.2 Interference. During the term of this Agreement and subject to
      existing customer uses of the Facilities authorized and disclosed to
      Pathnet in writing within thirty (30) days of the Effective Date, the LLC
      shall not license or otherwise permit any Person to use the Facilities or
      any Incumbent controlled facility if the use of such facilities by such
      Person would cause any Interference on the System. As of the Effective
      Date, the LLC shall not grant any Person a new or expanded right to use
      the Facilities or any Incumbent controlled facility which use would in any
      way cause Interference on the System. Notwithstanding the foregoing, in
      the event another Person causes any Interference on the System through any
      use of the Facilities or any Incumbent controlled facility which was not
      authorized prior to the Effective Date, the LLC shall, or the LLC shall
      cause Incumbent to, use best efforts to compel such Person using such
      facilities to immediately take all steps necessary to correct and
      eliminate such Interference, including, without limitation, enforcing
      provisions in any license or other agreement between Incumbent and/or the
      LLC and such Person using the facilities which allow Incumbent and/or the
      LLC to compel such Person to cease operation of such Person's system, to
      remove such Person's equipment or materials or to modify such Person's
      equipment or materials. The LLC acknowledges that any Interference shall
      cause irreparable harm to Pathnet and the prompt cessation of Interference
      is material to Pathnet's interest in the Facilities and Pathnet's
      performance under this Agreement and, as such, Pathnet shall be entitled
      to injunctive relief in the enforcement of this Section 6.2.2.


                                     -14-


      6.3 Visiting and Exiting Facilities. Upon exiting any Facility, Pathnet,
on behalf of itself and its employees, agents and Subcontractors, shall ensure
that such Facility is returned to a condition, which existed immediately prior
to such visit except for improvements made thereto and reasonable wear and tear.

      6.4 Clearances and Other Requirements. At the reasonable request of the
LLC, Pathnet shall require its employees, agents or Subcontractors to (i) apply
to the LLC for any necessary reasonable clearances and (ii) comply with all
other reasonable and applicable requirements, rules, regulations or ordinances
regarding any Person's ability to have access to the Facilities.

      6.5 Pathnet's Responsibility. Subject to LLC's payment obligations under
Section 5.1.5, Pathnet shall remain solely responsible for all actions of its
employees, agents, and Subcontractors in connection with the provision of
services to the LLC under this Agreement. Before allowing any Subcontractor to
commence work, Pathnet shall secure from such Subcontractor evidence of
insurance coverage covering such risks as are usually insured against by prudent
companies engaged in the business and activities in which such Subcontractor is
engaged.

      6.6 Subletting. Pathnet shall not grant any interest in the Facilities, in
whole or in part, to any Person without the prior written consent of the LLC and
Incumbent; provided, however, Pathnet shall have the right to transfer and
assign its rights or obligations under this Agreement to any successor or assign
in accordance with Section 18.7.

      6.7 Surrender. Upon the expiration of the Agreement in accordance with
Section 3, Pathnet shall peacefully and quietly surrender occupation of the
Facilities, without delivery by the LLC or Incumbent to Pathnet of any notice to
quit or demand for possession.

      6.8 Colocation. Subject to space availability at the Facilities at the
time of a Pathnet request, including LLC's or Incumbent's reasonably foreseeable
future space needs on the Facilities, the LLC shall or shall cause Incumbent to
allow Pathnet, at no additional charge to colocate at the Facilities all
equipment necessary to support the interconnections set forth on Exhibit A-6 to
Schedule A and any additional interconnections equipment that may be added by
Pathnet from time to time and at any time during the term of this Agreement,
subject to the limitations set forth in Schedule 3 of Schedule A.

      6.9 Subordination. Pathnet shall subordinate its interest in the
Facilities to (i) all deeds of trust, deeds to secure debts, mortgages and other
security instruments now or hereafter Encumbering all or any portion of the real
property relating to the Facilities described on Schedule G (each, a "Facility
Encumbrance") and (ii) any increases, renewals, modifications, consolidations,
replacements and extensions of any such Facility Encumbrance. In connection with
such subordination of Pathnet's interest in the Facility to all Facility
Encumbrances, Pathnet shall, as requested by the LLC, within fifteen (15) days
after any request by Incumbent, execute and deliver a commercially reasonable
subordination, non-disturbance and attornment agreement with all Persons secured
by such Facility Encumbrances. Pathnet shall, as requested by the LLC, execute
and


                                      -15-


deliver similar subordination, non-disturbance and attornment agreements with
each future Person secured by a Facility Encumbrance.

      6.10 Removal of Equipment. Upon the Expiration Date, the LLC shall have
the option of purchasing any and all of the Pathnet owned Equipment located on
the Facilities at its then fair market value. Pathnet shall, at the LLC's
request and direction, remove any or all Pathnet owned Equipment not so
purchased by the LLC from the LLC's Facilities and restore each site to its
condition as of Commissioning (reasonable wear and tear, and damage from the
elements, excepted) within sixty (60) days after the Expiration Date and at
Pathnet's sole expense. In the event Pathnet fails to perform such requested
removal within such sixty (60) day period, as determined by the LLC in its sole
discretion, the LLC may remove such Equipment and restore each site to its
condition as of Commissioning, (reasonable wear and tear, and damage from the
elements, excepted), and Pathnet shall promptly pay the LLC all costs reasonably
incurred by the LLC for such removal and restoration. The LLC shall have no
liability to Pathnet in connection with any damage to the Pathnet owned
Equipment resulting from its removal by the LLC.

      6.11 Removal of Hazardous Materials. Within ninety (90) days after the
written request of Incumbent, or in any event, within ninety (90) days after the

      carry on its business as owned and carried on as of the Effective Date.
      Such Party is duly licensed or qualified to do business and is in good

      hereby in accordance with the terms and conditions hereof: (i) will
      conflict with, violate, result in a breach of or constitute a default
      under any of the terms, conditions or provisions of the certificate or

      governing documents) of such Party or any material agreement or instrument
      to which such Party is a party or by which such Party may be bound, (ii)

      interests or rights or require any consent, authorization or approval
      under any contract to which such Party is a party or by which such Party
      is or may be bound or to which any equity interest held by such Party or
      any of its material properties or assets is subject or (iii) will result
      in the creation or imposition of any Encumbrance upon any equity interest
      held by such Party in the LLC or any of the other material properties or
      assets of such Party, other than Facility Encumbrances.

            14.1.3 No Consent. Other than consents and approvals contemplated by

      connection with the execution, delivery and performance of this Agreement
      or the consummation of the transactions contemplated hereby, except those
      that have been obtained and are in full force and effect pursuant to
      Section 14.1.5.

            14.1.4 Compliance with Laws and Regulations. The performance of its
      obligations under this Agreement will not result in a violation in any
      respect of (i) any applicable Federal, state, local or foreign laws,
      ordinances, regulations, rulings and orders of government agencies
      applicable to its business in any respect the violation of which could
      have a Material Adverse Effect (including Requirements of Law relating to
      pollution, protection of the environment, emissions, discharges, releases
      or threatened releases of pollutants, contaminants, chemicals, or
      industrial, toxic, hazardous or regulated substances or wastes into the

      (ii) any applicable order, Judgment, injunction, award or decree in any
      respect which could have a Material Adverse Effect on such Party.

            14.1.5 Permits. Such Party has or will obtain all authorizations,
      approvals, consents, licenses, Permits and certificates (including, but
      not limited to all required approvals from the FCC) necessary to perform
      its respective obligations under this Agreement and to own, lease and
      operate its properties as currently or anticipated to be conducted, owned,
      leased or operated, as the case may be, for which the failure to possess


                                      -27-


would result in a Material Adverse Effect. No violations are outstanding or
uncured with respect to any such Permits and no proceeding is pending to revoke
or limit any Permit.

            14.1.6 Title to Assets, Properties and Rights and Related Matters.
      Except as set forth in Section 6.2.1, 11.2 and 11.3 and on Schedule G,

      easements, proofs of dedication and rights necessary to ensure vehicular
      and pedestrian ingress and egress to and from any such properties or
      assets), free and clear of all Encumbrances of any kind or character,
      except (i) liens for current taxes not yet due and payable, (ii)
      Encumbrances securing taxes, assessments, governmental charges or levies
      or the Encumbrances of materialmen, carriers, landlords and like persons,

      character that do not substantially impair the assets or properties of
      such Party or which will not have a Material Adverse Effect on such Party.
      The LLC will cause Incumbent to use best efforts to keep in full force and
      effect any leases of or affecting the Facilities and will cause Incumbent
      to use best efforts to renew or enter into new leases for the Facilities
      as necessary to ensure that Incumbent has sufficient right, title and
      interest in and to the Facilities throughout the term of this Agreement
      and to permit the LLC and Pathnet to perform their respective obligations
      and rights hereunder.

            14.1.7 Labor Matters. Such Party has complied in all material
      respects with all applicable Federal, state and local laws and ordinances

      related thereto (except for currently accrued and unpaid wages and except
      for currently accrued withholding, payroll, unemployment and social
      security taxes payment of which is not overdue) or penalties for failure
      to comply with any of the foregoing, and neither has received a notice to
      the contrary from any Governmental Authority. Such Party has not suffered
      any strike, slowdown, picketing or work stoppage by any union or other
      group or employees affecting the business of such Party, and no such event
      or action is threatened.

            14.1.8 Contract or Restriction. Such Party is not a Party to or
      bound by any contract or agreement nor is subject to any corporate
      restrictions that could materially and adversely affect the business,
      properties or condition, financial or otherwise, of such Party (other than
      adverse effects resulting from vendor creditors exercising their rights
      against collateral pledged by such Party pursuant to applicable vendor
      credit documents) or adversely affect or call into question the power or
      authority of such Party to enter into or perform this Agreement or any of

      Party's knowledge, threatened actions or proceedings before any court,
      arbitrator or governmental or administrative body or agency that could in
      any way adversely affect or call into question the power or authority of
      such Party to enter into or perform this Agreement or any of the
      agreements or instruments executed in connection herewith, or that in any
      way adversely affect or call into question the validity or enforceability

      15.3 Indemnification Procedures. With respect to any third party claims,
the following procedures shall apply:

            (a) Notice. Promptly after receipt by an entity entitled to
      indemnification under Section 15.1 or Section 15.2 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 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 Agreement except to the extent that it can
      demonstrate damages attributable to such failure. Within fifteen (15) days
      following


                                     -30-


      receipt of written notice from the indemnitee relating to any claim, bill
      no later than ten (10) days before the date on which any response to a
      complaint or summons is due, the indenmitor shall notify the indemnitee in
      writing if the indenmitor elects to assume control of the defense and
      settlement of that claim (a "Notice of Election").

            (b) 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 provide prior written notice to 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 the subsection (a)
      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.

            (c) 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 or settle 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.

      15.4 Subrogation. In the event that an indemnitor shall be obligated to
indemnify an indemnitee pursuant to Section 15.1 or Section 15.2, the indemnitor
shall, upon payment of such indemnity in full, be subrogated to all rights of
the indemnitee with respect to the claims to which such indemnification relates.

SECTION 16. LIABILITY OF THE PARTIES TO EACH OTHER.

      16.1 Liability Generally. Subject to the specific provisions of this
Section 16, it is the intent of the Parties that each Party shall be liable to
the other Party for any actual damages incurred by the Non-Breaching Party as a
result of the Breaching Party's failure to perform its obligations in the manner
required by this Agreement and failure to cure such nonperformance as set forth
in Section 17.1.1.


                                         -31-


      16.2 Liability Restrictions.

            (a) SUBJECT TO SUBSECTION (b) BELOW, IN NO EVENT, WHETHER IN
      CONTRACT OR IN TORT (INCLUDING BREACH OF WARRANTY, NEGLIGENCE AND STRICT
      LIABILITY IN TORT), SHALL A PARTY BE LIABLE TO THE OTHER PARTY FOR
      INDIRECT OR CONSEQUENTIAL, EXEMPLARY, PUNITIVE OR SPECIAL DAMAGES EVEN IF
      SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES IN ADVANCE.

            (b) The limitations set forth in subsection 16.2 shall not apply
      with respect to damages occasioned by a violation of Section 13 of this
      Agreement.

            (c) Each Party shall have a duty to mitigate damages for which the
      other Party is responsible.

            (d) Each Party shall be liable to the other Party for any actual
      damages as set forth in Section 16.1 only if, and to the extent that the
      aggregate of all losses arising from or in connection with any failure to
      perform obligations in the manner required by this Agreement exceeds ten
      thousand dollars ($10,000.00), except with respect to any payment
      obligations set forth in Section 5.

      16.3 Force Majeure. No Party shall be liable for any breach, default or
delay in the performance of its obligations under this Agreement (i) if and to
the extent such default or delay is caused, directly or indirectly, by: fire,
flood, earthquake, elements of nature or acts of God, riots, civil disorders,
rebellions or revolutions in any country, changes in Requirements of Law
relating to the System or to the sale of Excess Capacity, or any other cause
beyond the reasonable control of such Party (a "Force Majeure Event"), (ii)
provided the non-performing Party is without fault in causing such breach,
default or delay, and such breach, default or delay could not have been
prevented by reasonable precautions and cannot reasonably be circumvented by the
non-performing Party through the use of alternate sources, work around plans or
other means.

SECTION 17. INFORMAL DISPUTE RESOLUTION; ARBITRATION.

      17.1 Informal Dispute Resolution.

            17.1.1 Notice of Breach, Cure and Remedies. In the event of a
      material breach by either Pathnet or the LLC (the "Breaching Party") the
      other Party (the "Non-Breaching Party") shall send by certified mail a
      written notice of such material breach to the Breaching Party setting
      forth the specific allegations of such breach. Upon receipt of the notice
      of breach, the Breaching Party shall have thirty (30) days to cure such
      breach. In the event the Breaching Party fails to cure such breach, as
      determined by the Non-Breaching Party in its sole discretion, or the
      Breaching Party determines, in its sole discretion, that it has cured such
      breach, either the Breaching Party or the Non-Breaching Party may invoke
      the settlement procedures set forth in Section 17 to resolve whether such
      breach has been cured.


                                        -32-


            17.1.2 Role of Program Manager. In the event the LLC has a dispute,
      controversy or other complaint relating to Pathnet's performance of
      Pathnet's rights and obligations under this Agreement, the LLC shall have
      the right to first contact the Program Manager to resolve such dispute,
      controversy or other complaint. If the LLC is not satisfied with the
      resolution provided by the Program Manager, the LLC may resort to the
      arbitration procedures set forth in this Section 17.

            17.1.3 Resolution of Disputes. Any and all disputes and
      controversies between the LLC and Pathnet concerning the negotiation,
      interpretation, performance, breach or termination of this Agreement (each
      a "Dispute") shall be subject to resolution as set forth in this Section
      17.

            17.1.4 Settlement Discussions. Any Dispute shall be attempted to be
      resolved first through amicable settlement discussions and each Party
      shall bear its own costs and attorney's fees of such settlement
      discussions. Each Party hereby agrees to use good faith efforts to reach a
      settlement through such amicable settlement discussions, provided,
      however, that, nothing herein shall prevent a Non-Breaching Party from
      immediately exercising any and all rights such Party may have, other than
      submission of such Dispute to arbitration or institution of legal
      proceedings, either of which remedies may only be invoked pursuant to the
      terms hereof and after failure of the settlement discussions required
      hereby.

            17.1.5 Referral to Binding Arbitration or Litigation. In the event
      the Parties fail to reach a settlement of the Dispute pursuant to
      settlement discussions in accordance with Section 17.1.4, each Party (the
      "Complaining Party") shall have the right, to file suit in a court of
      competent jurisdiction in a neutral forum or upon mutual consent of the
      parties, to refer such Dispute for final resolution by binding arbitration
      in accordance with the rules of the American Association of Arbitration
      (the "AAA"); provided, however, that the non-Complaining Party shall only
      have the right to institute suit regarding the Dispute in a court of
      competent jurisdiction prior to the commencement of the initial
      arbitration hearing, and upon filing such suit, the arbitration
      proceedings shall be deemed terminated.

            17.1.6 Binding Effect. The Parties acknowledge and agree that (i)
      the award in any arbitration shall be final, conclusive and binding on the
      Parties and (ii) any such arbitration award be a final resolution of the
      Dispute between the Parties to the same extent as a final judgment of a
      court of competent jurisdiction.

            17.1.7 Arbitration Process.

                  (A) Notice. To commence the arbitration process, the
            Complaining Party shall deliver to the other Party a written notice
            in accordance with the AAA rules.

                  (B) Site and Arbitration Tribunal. Absent agreement to the
            contrary by the Parties, the arbitration will be conducted in
            Washington, D.C., by a panel of three (3) arbitrators with expertise
            in the fields of telecommunications engineering and construction,
            provided, however, in the case of particular witnesses not subject
            to


                                      -33-


            subpoena at the designated hearing site, hearings may be held at any
            place designated by the arbitrators where such witnesses can be
            compelled to attend, and, with the consent of the Parties, before a
            single member of the arbitration tribunal. Within thirty (30) days
            after the deliverance of the notice of arbitration, each Party must
            select one (1) arbitrator and a third arbitrator will be selected by
            agreement of the two (2) arbitrators selected by the Parties. If
            either Party fails to select an arbitrator or there is no agreement
            on the selection of the third arbitrator, AAA will select such
            arbitrators.

                  (C) Transcripts and Evidence. Both Parties shall cause a
            written transcript of all proceedings and testimony to be kept and
            the cost of such transcript shall be borne equally by the Parties
            pending the final award. All documents that either Party proposes to
            offer in evidence, except for those objected to by the other Party,
            shall be deemed to be self-authenticating.

                  (D) Applicable Law. The arbitrators shall determine the claims
            and defenses of the Parties and render their final award in
            accordance with the governing law of this Agreement as set forth in
            Section 18.5. Notwithstanding anything set forth in the Arbitration
            Rules to the contrary, the provisions of this Section 17 shall
            govern any arbitration proceeding brought in relation to this
            Agreement or the transactions contemplated thereby.

                  (E) Sanctions. The Parties acknowledge that, in addition to
            any other remedy allowed or specified in or under the AAA rules, the
            failure of a Party to comply with any interim, partial or
            interlocutory order, after due notice and opportunity to cure such
            non-compliance, may be treated by the arbitrators as a default and
            all or some of the claims or defenses of the defaulting Party may be
            stricken and partial or final award entered against such Party, as
