(b) Financial Statement Schedules



     All financial schedules, other than that listed above, have been omitted
because the information required to be set forth therein is not applicable or
is shown in the Financial Statements or Notes thereto.


Item 17. Undertakings.

     The Registrant will provide to the Underwriters at the closing specified
in the Underwriting Agreement certificates in such denominations and registered
in such names as required by the Underwriters to permit prompt delivery to each
purchaser.

     Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable.

     In the event that a claim for indemnification against such liabilities
(other than the payment by the Registration of expenses incurred or paid by a
director, officer or controlling person of the Registrant in the successful
defense of any action, suit or proceeding) is asserted by such director,
officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.

                                      II-5

     The Registrant hereby undertakes that:

    (1) For purposes of determining any liability under the Securities Act,
   the information omitted from the form of Prospectus filed as part of a
   Registration Statement in reliance upon Rule 430A and contained in a form
   of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4), or
   497(h) under the Securities Act shall be deemed to be part of this
   Registration Statement as of the time it was declared effective.

    (2) For determining any liability under the Securities Act, each
   post-effective amendment that contains a form of prospectus shall be deemed
   to be a new registration statement relating to the securities offered
   therein and the Offering of such securities at that time shall be deemed to
   be the initial bona fide offering thereof.

sufficiency of the drawings and specifications.

of the Contractor for adjustment shall not be allowed unless he has given prompt
notice of such event;

Contract Documents with respect to its location and quantity shall be deemed to
be a differing site condition pursuant to this article. Hazardous material is
defined as PCB's, asbestos, or any other material, removal of which is governed

and the Contract Time.

of that provided by the Owner that it may require.


ARTICLE 6.  SURVEYS

In addition to the information required to have been furnished by the Owner

<PAGE>



reports describing the physical characteristics, soil, geological and subsurface
conditions, legal limitations, utility locations and legal description. The
Owner shall establish such land surveys and baselines so that the Contractor may
locate the principal parts of the Work and perform such detailed surveys to
perform the Work. The Contractor shall preserve all bench marks and reference
points established by the Owner and shall be responsible to restore them due to
any destruction caused by the Contractor's operations.


ARTICLE 7.  PROSECUTION OF THE WORK

and regulations, the Owner shall promptly be notified. Any necessary changes in
the Work as a result of such variance will entitle the Contractor to an
equitable adjustment in the Contract Price and the Contract Time.


ARTICLE 12.  INSPECTION OF WORK

12.1 The Owner shall provide sufficient competent personnel to visit and inspect
the site during the course of the Work to determine in general whether the Work

<PAGE>



acceptability of the finished Work, and defective work shall be corrected.

Work whenever it is in preparation or progress, and the Contractor shall provide
proper facilities for such access and for inspection.

Owner timely notice of its readiness for inspection and of the date fixed for
such inspection. Inspections by the Owner shall be made promptly, and, where

uncovered for examination and properly restored at the Contractor's expense,
unless the Owner has unreasonably delayed inspection.

12.4 If a portion of the Work has been covered which the Owner has not
specifically requested to observe prior to its being covered, the Owner may
request to see such work and it shall be uncovered by the Contractor. If such
work is in accordance with the Contract Documents, costs of uncovering and
replacement shall, by appropriate change pursuant to Article 15, be charged to
the Owner. If such work is not in accordance with the Contract Documents, the
Contractor shall pay such costs unless the condition was caused by the Owner or

of such costs.


ARTICLE 13.  WARRANTY

accordance with the Contract.

13.2 Prompt written notice of all defects in the Work shall be given to the
Contractor within one year of Substantial Completion. The Contractor shall at

payment.


ARTICLE 14.  PAYMENTS

14.1 The Owner shall pay to the Contractor the Contract Price, as may be amended
pursuant to Article 15, as full compensation for the Work.

14.2 Periodically, but not less frequently than monthly, the Owner shall pay the

                                       11

<PAGE>



payments and any payments or portions thereof that are in dispute. Disputed
payments will be resolved in accordance with Article 29. Payment shall be made
within ten (10) working days after submission of a properly documented
requisition.

14.3 The Contractor agrees that all work, materials and equipment covered by an
application for payment will pass to the Owner free and clear of all liens,
claims, security interests or encumbrances upon payment by the Owner. At the
request of the Owner, the Contractor shall provide waivers and lien releases
from all persons who may be potential lien claimants as a prerequisite to the
Owner's obligation to disburse progress and final payments.

14.4     This Article intentionally omitted.

14.5 Upon Final Completion and acceptance of the Work, the Owner shall pay the
Contractor all amounts remaining to be paid under the Contract, less any amounts
the Owner is entitled to retain under the other provisions of this Contract.


ARTICLE 15.  CHANGES

15.1 The Work shall be subject to change by additions, deletions or revisions by
Owner. The Contractor will be notified of such changes by receipt of additional
and/or revised drawings, specifications, exhibits or written orders.

15.2 Whenever an equitable adjustment in the Contract Price or the Contract Time
is provided for under the Contract Documents, or if the Owner has notified the
Contractor of a change, the Contractor shall submit to the Owner within a
reasonable time a detailed estimate together with any adjustments in the
schedule reflecting any changes in the Contract Price and the Contract Time.
Pricing shall be in accordance with the pricing structure of this Contract;
however, to the extent that such pricing is inapplicable, the cost of the change
or the amount of the adjustment shall be determined on the basis of cost to the
Contractor (except in the case of Contractor-owned equipment rates) plus
reasonable amounts for overhead and profit.

15.3 The Contractor shall not perform changes in the Work in accordance with
Paragraphs 15.1 and 15.2 (until the Owner has approved in writing the changes in
the Contract Price and Contract Time, except as set forth in Paragraph 15.4
below.) Upon receiving such written approval from the Owner, the Contractor
shall diligently perform the change in strict accordance with this Contract.

<PAGE>

          Confidential Materials omitted and filed separately with the
        Securities and Exchange Commission. Asterisks denote omissions.



15.4 Notwithstanding Paragraph 15.3, the Owner may expressly authorize the
Contractor in writing to perform the change prior to approval of price and
schedule adjustments by the Owner. The Contractor shall not suspend performance
of this Contract during the review and negotiation of any change, except as may
be directed by the Owner pursuant to Article 20, so long as the change is a
reasonably foreseeable alteration to the Work originally contemplated by the
Contract Documents. In the event the Owner and the Contractor are unable to
reach agreement on changes in the Contract Price and the Contract Time, the
matter shall be resolved in accordance with Article 17.

ARTICLE 16.  EXTENSIONS OF TIME

16.1 The Contract Time shall be extended as necessary to compensate for delay in
the progress of the Work resulting from changes in the Work authorized by Owner,
suspension of the Work (in whole or in part) by the Owner, any other act or
omission by the Owner or its employees, agents or representatives contrary to
the provisions of the Contract or by another contractor employed by the Owner,
or any other cause which could not have been reasonably foreseen, or which is
beyond the control of the Contractor, its subcontractors, and which is not the
result of their sole fault or sole negligence, including, but not restricted to,
acts of any governmental authority, acts of a public enemy, acts of God, fire,
unusual delay in transportation, abnormal weather, conditions, or labor disputes
(including strikes), and Owner's inability to secure applicable permits and
licenses.

16.2 The Contractor shall give to the Owner notice of any delay within five (5)
calendar days of the occurrence or commencement of a cause of delay. Failure to
give notice of any delay within a reasonable time shall constitute a waiver by
the Contractor of any claim for extension of the Contract Time resulting from
that cause of delay. The Contractor's notice shall include an estimate of the
probable effect of the cause of delay on the progress of the Work.

16.3 With respect to any delay resulting from any act or neglect by the Owner or
its employees, agents or representatives or by another contractor employed by
the Owner, and which delay is not otherwise specifically provided for in the
Contract Documents, the Contractor may recover from the Owner any damages
incurred as a result of such delay in accordance with Article 15.

16.4 With respect to any delay resulting from the fault or neglect of the
Contractor, any Subcontractor, or those under the control of either, the
Contractor shall pay to the Owner the sum specified in the attached Schedule D
[**] not as a penalty, but as liquidated damages, since the actual damages for
such delay are uncertain and would

                                       13

<PAGE>



be impracticable or extremely difficult to ascertain.


ARTICLE 17.  CLAIMS

17.1 Subject to the provisions of Article 15, the Contractor shall give to the
Owner written notice within a reasonable time after the happening of any event
which the Contractor believes may give rise to a claim for an equitable
adjustment in the Contract Price or the Contract Time. Within a reasonable time
after the happening of such event, the Contractor shall supply the Owner with a
statement supporting such claim, which statement shall include a detailed
estimate of the change in the Contract Price and the Contract Time. If requested
by the Owner in writing, the Contractor shall provide reasonable documentation
to substantiate its claim. The Contractor agrees to continue performance of the
Work during the time any claim is pending, so long as the work requested is a
reasonably foreseeable addition to the work originally contemplated in the
Contract Documents. The Owner shall not be bound to any adjustments in the
Contract Price or the Contract Time unless expressly agreed to by the Owner in
writing. No claim shall be allowed if asserted after final payment under this
Contract.

17.2 Claims by either party for damages due to injury or damage to person or
property or for delay, interference, suspension or interruption of work or for
any other damage shall be made in writing to the other party within a reasonable
time after the happening of such event or the first observance of such cause for
damage.


ARTICLE 18.  RIGHTS AND REMEDIES

18.1 The duties, obligations, rights and remedies in these Contract Documents
shall be cumulative, in addition to, and not a limitation of, any duties,
obligations, rights and remedies otherwise imposed or available by law, unless
otherwise indicated.

18.2 No action or failure to act by the Owner or Contractor shall constitute a
waiver of any right or duty afforded any of them under the Contract, nor shall
any such action or failure to act constitute an approval of, or acquiescence in,
any breach, except as may be specifically agreed in writing or specified in the
Contract.



                                       14

          Confidential Materials omitted and filed separately with the
        Securities and Exchange Commission. Asterisks denote omissions.


ARTICLE 19.  TERMINATION

19.1 Should the Owner become insolvent or commit a material breach or default
under the Contract, including, but not limited to, failure to pay timely
undisputed sums due to the Contractor, and fail to act in good faith to remedy
the same within ten (10) days after notice from the Contractor, then the
Contractor may terminate this Contract. The Contractor shall be entitled to all
damages incurred as a result of such termination.

19.2 Should the Contractor become insolvent, or should the Contractor refuse or
neglect to supply a sufficient number of properly skilled walkmen or tools
within the Contractor's control, or should the Contractor commit a substantial
breach of this Contract and should the Contractor fail to act in good faith to
remedy such within ten (10) days after written demand by the Owner, the Owner
may terminate this Contract. Upon any such termination, the Contractor shall be
compensated for all costs incurred for that portion of the Work then performed.
The Contractor shall be liable for any costs incurred by the Owner in completing
the Contract in excess of the difference between the Contract Price and the
amount paid to the contractor to the date of termination.

19.3 The Owner reserves the right to terminate the Work for its convenience upon
notice in writing to the Contractor. In such event, the Contractor shall be paid
its actual costs for that portion of the Work performed to the Date of
termination and for all costs of termination, including demobilization and any
termination charges by vendors and subcontractors, [**] of all such costs for
overhead and profit. If, for any reason, within six (6) months of the actual
date of cessation of work the Owner elects to resume the Work, using another
contractor, the Contractor shall be entitled to payment of its actual profits
for performance of all of the Work.

19.4 In the event the Contractor's insurance shall lapse, this Contract shall
immediately be suspended for three (3) days to allow the Contractor to reinstate
insurance coverage. No schedule extension shall be allowed for this event.


ARTICLE 20.  SUSPENSION OF WORK

20.1 The Owner may at any time by notice to the Contractor suspend further
performance of all or any portion of the Work by the Contractor. The notice
shall specify the date and the estimated duration of the suspension. Any
suspension shall not exceed forty-five (45) consecutive calendar days nor shall
the total of all

                                       15

<PAGE>



suspensions exceed ninety (90) calendar days. Upon receiving any such notice,
the Contractor shall promptly suspend further performance of the Work to the

      time as the Grantor determines is needed to compensate for changes to the
      original scope of work including but not limited to unplanned Make Ready
      Work. The Grantor will submit the adjustment to Estimated Cost to the
      Grantee. The Grantor shall reimburse the Grantee if the Actual Cost of the
      work performed up to the date of the adjustment is less than the amount(s)
      actually paid by the Grantee based on the Estimated Cost. If the Actual
      Cost of the work performed up to the date of the adjustment is greater
      than the Estimated Cost, the Grantor shall submit an invoice to the
      Grantee for the payment of the difference within the time provided in the
      Payment Schedule. The Grantee shall not pay for any of Grantor's work
      needed to enable the Grantor to satisfy the requirements of Section 17.3
      hereof.

detail as is reasonably required by the Grantor to satisfy the Grantor's
property records.

4.    THE ROUTE; MODIFICATIONS

      4.1 Withdrawal of [**] Route Segments by Grantor. During the sixty-day
period following the date of execution of this Agreement, the Grantor shall have
the right to withdraw any portion of the [**] Route that Grantor deems, at its
sole discretion, not to be suitable for the Cable; provided that the Grantor
will provide Grantee with a substitute Route Segment. Following the conclusion
of the sixty-day period, Grantor shall not withdraw any portion of the [**]
Route Segment, except for the reasons set forth in Section 19.4.1.

          4.1.1 Substitute Route Segments. When required to do so under Section
4.1 above, Grantor will provide Grantee with a substitute Route Segment,
reasonably acceptable to the Grantee, to such destinations of the withdrawn
Route Segment, and in every manner replicating the functionality of the Route
Segment withdrawn. Should the substitution of the new Route Segment (1) occur
after the conclusion of the sixty-day period in Section 4.1 above, and (2)
result in any additional cost to Grantee, then (a) such additional cost
resulting from the substitution of the new Route Segment shall be solely borne
by Grantor, and (b) the Annual Fee for the substituted Route Segment shall be
the lesser of the amount due for (i) the Route Segment withdrawn or (ii) the
substituted Route Segment as calculated under Section 20.

          4.1.2 Distribution Facilities. Notwithstanding the foregoing, should
Grantor relocate any of its distribution facilities, whether before or after the
expiration of the sixty-day period set forth in Section 4.1 or before or after
the installation of the Cable on any portion of the Route Segment, Grantee shall
pay all costs associated with the relocation of the Cable. If the relocation
occurs prior to the installation of the Cable on the distribution facilities,
Grantee shall be responsible for any additional Make Ready Work cost resulting
from the relocation.

      4.2 Network Additions Designated by Grantee. If from time to time, the
Grantee wishes to extend the Route by installing additional Cable on Grantor's
Structures, the Grantee shall submit plans of said Network Addition to the
Grantor for approval, which approval shall not be unreasonably withheld or
delayed. All such Network Additions, if approved, shall be incorporated as part
of the Route, once it is installed, under the Agreement.

a Network Addition, Grantor shall not withdraw its approval of the Network
Addition, or, once the Cable is installed, terminate the resulting Route Segment
except pursuant to, and for one or more of the reasons provided in, Section
19.4.1. Grantor shall thereupon provide Grantee with an alternative Route
Segment, if possible. Grantee shall bear the cost of relocating the Cable
Segment, and the Annual Fee shall be based on the new Route Segment.

      4.3 Modification of the Route by Grantee. If, prior to the installation of
Cable on any Route Segment or on any Network Addition, Grantee determines, after
reviewing the Estimated Cost, that such installation would require unusual
expense, then the Grantee shall have the right, subject to the Grantor's
approval, to designate a substitute Route Segment.

      4.4 Network Additions Designated by Grantor. If the Grantor shall
determine any need for Network Additions for the purpose of expanding the
CMPNET, the Grantee shall have the first right to provide such Network
Additions. If for any reason, the Grantee is unwilling or unable to provide such
Network Additions on the terms requested by the Grantor, the Grantor shall be
free to interconnect additional communications facilities with the CMPNET, or
acquire such additional facilities from Third Parties on substantially the same
or better terms as those proposed to the Grantee. If the Grantor shall obtain
such communications facility from Third Parties, the Grantor shall, if requested
to do so by Grantee, use its best efforts to provide Grantee with the unimpeded
use of not less than [**] in such facilities with Grantee paying the incremental
cost of owning, operating and maintaining its portion of the facilities.

      4.5 Cost and Means of Right of Way Acquisitions. The Grantee shall be
responsible for the acquisition of, and payment for, any easement or other
rights that may be required in order to permit the installation, operation and
maintenance of the Cable on the Grantor's Structures.

      4.6 Eminent Domain. If the use of the power of eminent domain is necessary
in order to acquire any additional right-of-way rights required for the use of
NEON by the Grantee, then any required condemnation action shall be brought by
the Grantee in its own behalf. Any easement or other property right obtained by
Grantee through eminent domain shall be subsequent and subordinate to any
existing rights of Grantor in the property.

on the Grantor's property or easements or Structures without prior written
approval of the Grantor. The cost of any such work shall be paid by the Grantee.

      9.2 Due to the Requirements of the Grantor. In the event that during the
Term of this Agreement the Grantor is required by public authorities or by
lawful order or decree of a regulatory agency or court or business need to
relocate or modify any or all Structures upon which the Cable is located, all
costs associated with such relocation or modification to the Structures shall be
borne by Grantor. The Grantor and the Grantee shall cooperate in performing such
relocation or modifications so as to minimize any interference with the use of
NEON or CMPNET by either Party and to avoid unreasonably impairing the ability
of each to provide communications services of the type, quality and reliability
contemplated by this Agreement. The Grantee shall relocate the Cable at the
Grantee's sole cost; provided that if the relocation or modification to the
Structures is undertaken to permit a competitor of Grantee to attach to said

who may

                                      -13-

<PAGE>



be liable. Should the Cable fail to function for any reason, the Grantee shall
have the obligation to expeditiously replace the Cable, subject to the terms and
conditions of this Agreement governing the original installation, and at the
Grantee's sole cost and expense. The Grantee shall have no responsibility for
Equipment to be used solely in connection with CMPNET, including without
limitation, any such equipment installed or located in the Grantor's Space in
any New Building or at any of the Grantee's facilities. To the extent the
Grantee realizes any proceeds from the Grantor's assignment of its warranty
rights to the Cable that are not expended in replacing Cable, such proceeds
shall be retained by the Grantee.

      12.1 By Grantor. The Grantor shall have the right, but not the obligation,
to make Periodic Inspections of any part of the Grantee's operations that are
placed on or occupying the Grantor's property. The Grantor will give the Grantee
reasonable advance notice of any Periodic Inspections, except in those instances
where, in the sole judgment of the Grantor, safety considerations justify the
need for an immediate Periodic Inspection. A representative of the Grantee may,
at Grantee's sole cost, accompany the Grantor's representative on all Periodic
Inspections. The cost of

                                      -14-

<PAGE>



Periodic Inspections work performed under this Section 12.1 shall be included in
the Grantee's annual payments set forth in Section 20.

      12.2 Grantee's Obligations. The making of Periodic Inspections or the
failure to do so shall not impose upon the Grantor any liability of any kind
whatsoever nor relieve the Grantee of any responsibility, obligations or
liability assumed under this Agreement.

13.   APPROVALS AND CONSULTATION

      13.1 Role of Program Managers. Each party shall designate a Program
Manager ("Program Manager"). Whenever either party is entitled to approve a
matter, the Program Manager for the party seeking the approval of the other
party shall notify the Program Manager of the other party of the nature of such
matter and the approval requested. The Program Managers shall discuss such
matter, and each Program Manager is authorized to approve such a matter on

the other party," it is intended that such consultation shall be thorough and
meaningful, and that the views of the each party with regard to the matter under
consultation shall be given the weight appropriate to the experience and
expertise of the Grantee in communications and the Grantor in electric power.
Whenever in this Agreement it is provided that the approval of one party is
required, it is intended that such approval will not be unreasonably withheld or
delayed by the other party.

14.   OWNERSHIP

      14.1 Title; Tax Cost Reimbursement. Legal title to the Cable and Cable
Accessories on any Route Segment shall be transferred from the Grantee to the
Grantor on the Installation Date of that Route Segment. Both legal and
beneficial ownership of CMPNET, shall, subject to the terms of this Agreement be
transferred to Grantor on the Installation Date of any Route Segment. In the
event the acquisition of (a) legal title to the Cable and Cable Accessories,
and/or (b) the beneficial ownership of CMPNET, constitute(s) a taxable event(s)
to the Grantor, the related Tax Cost of Grantor's acquisition of legal title to
the Cable and Cable Accessories, and/or beneficial ownership of CMPNET, will be
paid by Grantee with respect to each Route Segment.

      14.2 Tax Accounting. With respect to NEON fibers contained in the Cable,
and the Cable Accessories installed upon the Grantor's Structures, the Grantor
shall hold legal title to the same as the Grantee's nominee and, with respect to
such

                                      -15-

<PAGE>



property, the Grantee will be the beneficial owner, and Grantee will assume such
beneficial ownership of the NEON fibers on the Date of Installation.
Accordingly, the Grantee shall for tax purposes account for the NEON fibers as
the owner thereof and, as between the parties, shall be entitled to any
investment tax credits, depreciation and any other tax attributes or liabilities
with respect to those fibers and Cable Accessories. The Grantor agrees that it
will not, for tax purposes, account for the property associated with NEON fibers
and the Cable Accessories as though it were the tax owner thereof and shall not
attempt to claim any of the tax attributes or liabilities with respect thereto.
The parties agree they shall file all income tax returns and otherwise take all
actions with respect to taxes in a manner which is consistent with the
foregoing.

      14.3 Income Tax. Pursuant to Section 14.1, Grantee shall reimburse Grantor
for any income tax liability incurred by Grantor as a result of the transfers
described therein. Grantor shall take reasonable efforts suggested by Grantee to
minimize the amount of said tax liability on its return(s), in accordance with
applicable laws and regulations. Within seven days of the execution hereof,
based upon fifteen-year depreciation schedule, the Grantor shall furnish Grantee
an estimate of this tax liability, based on Grantor's allocable share of the
total cost of a Route Segment, such allocation to be derived based on the ratio
of CMPNET to NEON fibers in the Route Segment. Grantee shall hold harmless,
indemnify, and defend Grantor's tax position with respect to the transfers
described in Section 14.1 if challenged by the IRS. In lieu of cash, Grantee
shall provide said reimbursement in the form of additional fiber segments,
engineering services, or other telecommunication services that Grantor may
request from Grantee from time to time and which Grantee agrees to provide,
which segments, and/or services shall have a value (grossed up to take account
for the time value of money and the timing of the actual tax payments)
equivalent to Grantor's tax liability described in this Section 14.3. If said
reimbursement has not been attained on the eighth anniversary of this Agreement,
Grantee agrees to commence the payment specified at a rate sufficient to
liquidate the remaining obligation by the enth anniversary of this Agreement,
provided that such payments do not put the Grantee in default of any financial
agreement then in place. If such payments could cause an event of default under
any financial agreement, the parties agree to use their best efforts to devise
an alternative payment plan that would repay the obligation by the tenth
anniversary of this Agreement without causing such default. Thereafter, the
payment as specified and agreed to by the parties shall be due and owing. In a
given year, however, Grantee shall only be obligated to provide reimbursement
valued up to an amount equal to the actual tax liability incurred by Grantor for
the prior tax year, plus any unused reimbursements amounts from earlier years.

      14.4 Reversion of Beneficial Ownership. Beneficial ownership of the
Grantee's NEON fibers and the Cable Accessories shall revert to the Grantor upon
termination or expiration of the Agreement pursuant to the Term and Termination
Section 19 herein. Reversion of Beneficial Ownership in the NEON fibers and the
Cable Accessories pursuant to this Section 14.4 or Section 16 or as a result of
action taken by federal tax authorities in the form of Internal Revenue Service
audit examination adjustments or other guidance may constitute a taxable event
to the Grantor, in which case Grantee shall not pay to the Grantor the related
Tax Cost.

15.   USE OF THE CABLE BY GRANTOR

      15.1 CMPNET. The Grantee shall provide [**] in the Cable for the unimpeded
and unrestricted use by the Grantor, subject to Section 15.2 except that the
requirement of usability shall not apply to any fibers located upon a Route
Segment which Grantee is no longer using for NEON purposes.

      15.2 Fibers and Use. For a period of [**] commencing upon the Installation
Date, Grantor's use of CMPNET shall be restricted to Grantor's Internal Business
Purposes, except by the written permission of Grantee, such permission not being
subject to reasonableness ("Restricted Period"). Following said period, the
Grantor's use of CMPNET is unrestricted.

      15.3 Unrestricted Period. Should Grantor determine, at the conclusion of
the Restricted Period, that it has CMPNET capacity that is excess to its
then-current and then-projected needs, prior to marketing any such excess to
third parties, Grantor shall negotiate in good faith with Grantee to agree on
terms to provide such excess to Grantee.

      15.4 Additional Service. In addition to providing CMPNET, Grantee shall,
upon the Grantor's request, provide the Grantor with communication facilities
into all locations served by the Grantee's networks, but not served by CMPNET,
[**].

      15.5 Space in Grantee's Locations. Where available and requested by the

thereof, the parties' continued performance hereunder, or with respect to any
portion of the Structures and the Cable, will be irreparably impaired or
prevented, the parties may mutually agree to terminate this Agreement, in whole
or in part as to the Route or any Route Segment so affected with no further
obligation or liability. The parties will attempt to provide a date of
termination such that the parties will have a reasonable time to provide a
substitute Route or Route Segment, or otherwise to

                                      -22-

shall not excuse, or extend the time period for, any payment due hereunder;
except under circumstances in which the Force Majeure event prevents Grantee
from using NEON, in which case the time period for payment shall only be
suspended for the duration of the Force Majeure Event.

22.   PROPRIETARY INFORMATION

      22.1 Obligation to Maintain as Confidential. Each party acknowledges that
in the course of the performance of this Agreement it may have access to
privileged and proprietary information claimed to be unique, secret, and
confidential, and which constitutes the exclusive property and trade secrets of
the other ("Proprietary Information"). This information may be presented in
documents marked with a restrictive notice or otherwise tangibly designated as
proprietary or during oral discussions, at which time representatives of the
disclosing party will specify that the information is proprietary and shall
subsequently confirm said specification in writing within five days. Each party
agrees to maintain the confidentiality of the Proprietary Information and to use
the same degree of care as it uses with regard to its own proprietary
information to prevent the disclosure, publication or unauthorized use of the
Proprietary Information. Neither party may duplicate, copy or use Proprietary
Information of the other party other than to the extent necessary to perform
this Agreement. Either party shall be excused from these nondisclosure
provisions if the Proprietary Information received from the other party (a) has
been or is subsequently made public by the other party, (b) is independently
developed by such party, (c) is disclosed pursuant to order by a court or
government agency of competent jurisdiction, (d) is disclosed to avoid
committing a violation of law; provided that 10 days notice first be given to
the non-disclosing party so that a protective order, if appropriate, may be
sought by the non-disclosing party, (e) is disclosed following express, prior
written consent given by the other party, or (f) is

                                      -23-

disclosed to governmental bodies to obtain necessary approvals, provided that a
protective order shall be sought.

      22.2 Route Constitutes Proprietary Information. The Route, the identity of
the Grantee's customers and its contracts with customers are deemed Proprietary
Information without further notice and will not be disclosed by the Grantor
absent an order by a court or regulatory body with jurisdiction over the
Grantor, or as provided in 22.1(f) above.

      22.3 Publicity and Advertising Limitations. In connection with this
Agreement, (i) neither party shall publish or use any advertising, sales
promotions, or other publicity materials that use the other party's logo,
trademarks, or service marks or employee name(s) without the prior written
approval of the other party; (ii) each party agrees not to issue any such
publicity materials, press releases or material produced by the public relations
department of the other party without written consent; (iii) unless otherwise
agreed, neither party shall disclose the existence of this Agreement or release
any material portion thereof, other than in a form modified to remove all
references to the identity of the other party. The provisions of this paragraph
shall not apply to reasonably necessary disclosures in, or in connection with,
regulatory filings or proceedings, financial disclosures which in the good faith
judgment of the disclosing party are required by law, or disclosures that may be
reasonably necessary in connection with the performance of this Agreement.

23.   ACCESS AND SECURITY

      23.1 Access by Grantor. With respect to any facility controlled by the
Grantee, the Grantee agrees, upon reasonable request, to allow the Grantor
direct ingress and egress to all Grantor Space, and to permit the Grantor to
perform any appropriate maintenance and repair of CMPNET equipment in such
space; provided that a representative of the Grantee must accompany any
representatives of the Grantor having access to such Space, except in buildings
having separate entrances providing access to Grantor's Space only to Grantor.
Employees and agents of the Grantor shall, while on the premises of the Grantee,
comply with all Grantee rules and regulations, including without limitation
security requirements, and, where required by government regulations, receipt of
satisfactory governmental clearances. The Grantor shall provide to the Grantee a
list of the Grantor's employees or persons authorized as the Grantor's designee
who are performing work on, or who have access to such Space. The Grantee shall
have the right to notify the Grantor that certain of Grantor's persons are
excluded if, in the reasonable judgment of the Grantee, the exclusion of such
employees is necessary for the proper security and maintenance of the Grantee's
facilities.

      23.2 Access by Grantee. The Grantor agrees, upon reasonable request, to
allow the Grantee direct ingress and egress to all Grantor Space to be provided
to the

                                      -24-

Grantee, and to permit the Grantee to be on the Grantor's premises at a date and
time acceptable to the Grantor for the Grantee to perform any appropriate
maintenance and repair of Equipment located at such space. The Grantor may
require that a representative of the Grantor accompany any representatives of
the Grantee having access to such space. Employees and agents of the Grantee
shall, while on the premises of the Grantor, comply with all of Grantor's rules
and regulations, including without limitation security requirements, and, where
required by government regulations, receipt of satisfactory governmental
clearances. The Grantee shall provide to the Grantor a list of the Grantee's
employees or authorized Grantee designees who are performing work on, or who

necessary for the proper security and maintenance of the Grantor's facilities.

      23.3 Grantee's Work. The Grantee shall at all times perform its work in
accordance with the Grantor's safety and work procedures and in accordance with
the applicable provisions of OSHA and the National Electrical Safety Code, and
any employees, agents or contractors retained by Grantee to perform work on
energized Structures must satisfy Grantor's qualifications for such work, as
reasonably determined by Grantor prior to the commencement of such work. The
Grantor shall have the authority to suspend the Grantee's work operations in and
around the Grantor's property if, in the sole judgment of the Grantor at any
time hazardous conditions arise or any unsafe practices are being followed by
the Grantee's employees, agents, or contractors. The Grantee agrees to pay the
Grantor for having the Grantor's employee or agent present when the Grantee's
work is being done in and around the Grantor's property. Such charges shall be
at the Grantor's Actual Cost. The presence of the Grantor's authorized employee
or agent(s) shall not relieve the Grantee of its responsibility to conduct all
of its work operations in and around the Grantor's property in a safe and
workmanlike manner, and in accordance with the terms and conditions of this
Agreement.

24.   NO JOINT VENTURE; COSTS

      24.1 Relationship. In all matters pertaining to this Agreement, the
relationship of the Grantor and the Grantee shall be that of independent
contractors, and neither the Grantor nor the Grantee shall make any
representations or warranties that their relationship is other than that of
independent contractors. This Agreement of and by itself is not intended to
create nor shall it be construed to create any partnership, joint venture,
employment or agency relationship between the Grantee and the Grantor, and no
party hereto shall be liable for the payment or performance of any debts,
obligations, or liabilities of the other party, unless expressly assumed in
writing.

26.   SEVERABILITY

      If any part of any provision of this Agreement or any other agreement,
document or writing given pursuant to or in connection with this Agreement shall
be invalid or unenforceable under applicable law, said part shall be ineffective
to the extent of such invalidity only, without in any way affecting the
remaining parts of said provision or the remaining provisions of said agreement;
provided, however, that if any such ineffectiveness or enforcement of any
provision of this Agreement, in the good faith judgment of either party, renders
the benefits to such party of this Agreement as a whole uneconomical in light of
the obligations of such party under this Agreement as a whole, then the other
party shall negotiate in good faith in an effort to restore insofar as possible
the economic benefits of this Agreement to such party.

27.   LABOR RELATIONS

      27.1 Notice by the parties. Each party agrees to notify the other

Grantee facility are causing or will cause labor difficulties for the Grantee,
the Grantor agrees to discontinue those activities until the labor difficulties
have been resolved; provided, however, that in any such event and

the period of such labor difficulties perform at its own expense any such
activities that may be reasonably necessary to the operation and maintenance of
CMPNET or any portion thereof.

      27.3 Determination by Grantor. If the Grantor determines that the
Grantee's activities pursuant to this Agreement in any Grantor facility are

activities that may be reasonably necessary to the operation and maintenance of
NEON or any portion thereof.

provision of this Agreement for a period of 60 days after notice by the other
party of such default, or 30 days with respect to a failure to make any payment
due hereunder or to maintain insurance, the party so notifying the other party
may, at its option, terminate this Agreement; provided, however, that, in the
case of default other than to make any payment due hereunder or to maintain
insurance, where the party in default proceeds with all due diligence to cure
such default and cure is not possible within such 60 days, then the party then
in default shall have such time to cure the default as is reasonably necessary,
but not to exceed an additional 180 days.

      31.3 The Grantee shall not make any payments under this Agreement in
advance of the time such payments are due.

32.   ASSIGNMENT

      32.1 By Grantee. Subject to Section 33, the Grantee may not assign or
otherwise allow use of its rights under this Agreement to any person or entity
other than an Affiliate of Grantee, without the express prior written approval
of the Grantor. The Grantor's approval will be granted provided the new person
or entity demonstrates to the reasonable satisfaction of the Grantor that the
proposed assignee is financially and operationally fit, willing and able to
discharge its obligations under this Agreement, acquires substantially all of
the Grantee's business within the geographic area of such assignment, including
substantially all of the assets used in such business, and agrees to be bound
directly and fully by all of the terms and conditions of this Agreement.

      32.2 Grantee's Change of Control. Any change of control of the Grantee
shall be deemed an assignment if a new person or entity other than an Affiliate,
directly or indirectly, acquires 50% or more of the voting interest of the
Grantee in one or more related transactions.

      32.3 Grantor's Right to Pledge Agreement and Transfer Property. The
Grantor shall be free to mortgage, pledge, or otherwise assign its interests
under this Agreement to any Third Party in connection with any borrowing or
other financing activity of the Grantor provided that such assignment shall not
limit or otherwise affect the Grantor's obligations or the Grantee's rights
under this Agreement. Any transfer of property of the Grantor included in or
subject to this Agreement may be made by the Grantor, provided the person
acquiring such property takes it subject to this Agreement.

      32.4 Grantee's Right to Pledge Agreement and Lease Fibers. The Grantee may
mortgage, pledge or otherwise assign its interest under this Agreement to any
Third Party in connection with any borrowing or other financing activity of the
Grantee provided that such assignment shall not limit or otherwise affect the
Grantee's obligations under this Agreement. Nothing herein shall limit or apply
to the Grantee's right to lease or sublease fibers of which it has the use under
this Agreement to Third parties in the normal course of the Grantee's business
provided that such leases or subleases do not interfere or conflict with the
Grantor's rights under this Agreement.

      32.5 Right to Assign. This Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and permitted
assigns.

33.   GOVERNMENTAL APPROVALS, PERMITS, AND CONSENTS

      33.1 Grantee's Obligations. During the term of this Agreement, the Grantee
shall continuously comply with all governmental laws, regulations or ordinances
as may now or in the future be applicable to the Grantee's use and operation of
NEON and the Cable.

      33.2 Grantor's Obligations. During the term of this Agreement, the Grantor
shall continuously comply with all governmental laws, regulations or ordinances
as may now or in the future be applicable to the Grantor's use and operation of
CMPNET and the Cable.

      33.3 Opinion. Within 60 days of the date of this Agreement, the Grantee
shall provide the Grantor with an opinion of counsel in form and substance
satisfactory to the Grantor, stating the Grantee's compliance with the
provisions of law applicable to the Grantee's use of the Cable and its
obligations under this Agreement.

      33.4 Compliance with Regulatory Conditions. The parties acknowledge that
this Agreement shall be subject to the conditions established by the Maine
Public Utilities Commission in its November 15, 1996 Order in Docket 96-537
approving this transaction, any subsequent orders in said Docket, and any orders
issued by said Commission that directly affect this Agreement (collectively
"Regulatory Conditions"). Subsections 33.4.1 below constitutes the understanding
of the parties as to the implementation, for the purposes of this Agreement, of
the access and relocation conditions included in the Commission's October 29,
1996 Order in Docket 96-421 (the "96-421 Order"), made applicable to this
transaction by the Commission's November 15, 1996 Order in Docket 96-537. (See
Exhibit 17.1 hereof.) With respect to any Regulatory Condition imposed by the
Commission, (i) the parties agree to bargain in good faith to accommodate such
Regulatory Condition in a manner that preserves, to the maximum degree possible,
the parties understandings hereunder

                                      -30-

<PAGE>



and which minimizes any expense to be incurred, and (ii) to the degree that any
such accommodation requires Grantor to incur expenses, forego any revenues, or
undertake any duty beyond that contemplated in this Agreement, Grantee shall
reimburse Grantor its Actual Cost associated therewith.

          33.4.1 Access. The parties agree to accommodate the Commission's pole,
access and line transfer conditions, set forth in pages 6-7 and page 8 of the
Commission's October 29, 1996 Order in Docket 96-421, as follows:

            (a) Route Segment Selection. If requested to do so by Grantee,
      Grantor will (a) advise Grantee regarding the degree to which pole or
      conduit space will be available for any potential post-Grantee prospective
      attacher on any Route Segment which Grantee is considering for a Network
      Addition, and (2) will assist Grantee in selecting Route Segments where
      additional attachment space is likely to be available following
      installation of the Cable along such new Route Segments.

            (b) Capacity Availability. In sizing the cable to be installed on
      any Route Segment, Grantee will take into consideration the possibility
      that it will need to accommodate an entity whose request for attachment to
      Grantor's structures along any installed Route Segment cannot be
      accommodated due to lack of space on Grantor's structures (a "Disappointed
      Attacher").

            (c) Provisioning of Fiber Capacity. When requested to do so, Grantee
      will make available fiber capacity to any Disappointed Attacher at prices
      commensurate with prices charged by Grantee to other similarly situated
      entities, provided Grantee has such available capacity and provided that
      such Disappointed Attacher's use of said capacity will not cause Grantee
      to become a public utility or otherwise a Telephone Company under
      governmental regulations.

            (d) Rebuilding Structures. Grantor agrees to cooperate with Grantee
      and to use its best efforts to accommodate the reasonable requests of any
      Disappointed Attacher. In addition, in the event that Grantor considers a
      Disappointed Attacher to have acted unreasonably with respect to its
      demands as to any Route Segment, Grantor will work with Grantee to obtain
      relief from the Public Utilities Commission of any requirement to rebuild
      its structures along any Route Segment to accommodate a Disappointed
      Attacher. However, in the event that Grantor shall be required by
      Commission order, including the terms of the 96-421 Order, to rebuild any
      of its Structures due, in whole or in part, to accommodate the Cable on
      the Grantor's Structures, Grantee shall reimburse Grantor its Actual Cost
      for the rebuild including the cost to transfer existing lines to the new
      Structure; provided that if, with respect to any portion of any Route
      Segment to which a Regulatory Affiliate of Grantor has a

                                      -31-

<PAGE>



      cable attached (in addition to the Cable), Grantee shall only reimburse
      one-half of Grantor's Actual Cost for rebuilding its Structures and
      transferring lines on said portion.

35.   DISPUTE RESOLUTION

      35.1 Nonbinding Procedure. The purpose of the dispute resolution process
shall be to create a nonbinding procedure to help resolve disputes in excess of
$50,000.00 which cannot be resolved by negotiation between the Grantor and the
Grantee within a reasonable time, but, in no case to exceed 90 days from the
date of first notice of a claim of dispute by either party.

      35.2 Mediation. Upon expiration of 45 days after notice of a claim of
dispute by either party to the other, or sooner if agreed by both parties, the
dispute shall be submitted to an independent, neutral Third Party with
recognized knowledge and expertise in the law, utility and telecommunications
industries and the mediation process. The mediator shall be a member to the
American Arbitration Association and shall be chosen by the parties. In the
event that the parties are unable to agree on a mediator, then each Party shall
select a mediator and the two mediators so chosen shall pick a mediator who
shall mediate the dispute.

      35.3 Cost. The cost of such mediation shall be born equally by both
parties.

called by either party to testify concerning the mediation or to provide any
materials in any subsequent dispute resolution process, whether litigation or
otherwise. Failure to comply with this paragraph shall void the claim of the
Party so failing to respect the confidentiality of the mediation process with
respect to all aspects of that particular dispute.

      35.5 Findings. Either party may reject the findings or recommendations of
the mediator. If such rejection is made, either party shall be free to seek
relief with respect to the subject matter of the dispute in any court of
competent jurisdiction.

                                    termination), any successor to the business
                                    or operations of the Company, and any
                                    business entity spun- off, divested, or
                                    distributed to shareholders which shall

                                    of this Agreement. The Employee agrees that
                                    the Company shall be entitled to injunctive
                                    relief to prevent any breach or threatened
                                    breach of these provisions. In the event of
                                    a failure to comply with part (i), (ii) or
                                    (iii) of this Section 8, the Employee agrees
                                    that the Company shall have no further
                                    obligations to pay the Employee any
                                    Severance Benefits under Section 5 of this
                                    Agreement.

         9. No Mitigation.  The Employee shall not be required to mitigate the
amount of any payment provided for in this Agreement by seeking other
employment.

         10. Assignment. This Agreement and the rights and obligations of the
Company hereunder shall inure to the benefit of and shall be binding upon the
successors and assigns of the Company, including without limitation any
corporation or other entity acquiring all or substantially all of the business
or assets of the Company whether by operation of law or otherwise. This
Agreement and the rights of the Employee hereunder shall not be assignable by
the Employee, and any assignment by the Employee shall be null and void.

         11. Arbitration. Any dispute or controversy arising under or in
connection with this Agreement shall be settled exclusively by arbitration in
Boston, Massachusetts, in accordance with the rules of the American Arbitration
Association then in effect. The pendency of any such dispute or controversy
shall not affect any


                                       10


<PAGE>



rights or obligations under this Agreement.  Judgment may be entered on the
arbitrator's award in any court having jurisdiction.

         12. Waiver; Amendment. The failure of either party to enforce, or any
delay in enforcing, any rights under this Agreement shall not be deemed to be a
waiver of such rights, unless such waiver is an express written waiver which has
been signed by the waiving party. Waiver of any one breach shall not be deemed
to be a waiver of any other breach of the same or any other provision hereof.
This Agreement can be amended only by written instrument signed by each party
hereto and no course of dealing or practice or failure to enforce or delay in
enforcing any rights hereunder may be claimed to have effected an amendment of
this Agreement.

         13. Singular Contract. This Agreement is a singular agreement between
the Employee and the Company, and is not part of a general "plan" or "program"
for employees as a group. This Agreement shall, under no circumstances, be
deemed to be an "employee welfare benefit plan" or an "employee pension benefit
plan" as defined in the Employment Retirement Income Security Act of 1974
(hereinafter referred to as "ERISA"). Notwithstanding, the Company may submit a
letter to the Department of Labor indicating the possible establishment of a
so-called unfunded "top hat" plan for the benefit of a select group of
management and highly compensated employees to avoid the costs and uncertainties
which may occur in the event of a Department of Labor audit and challenge
relative to compliance with any allegedly applicable provisions of ERISA. The
Employee specifically acknowledges and agrees that the filing of the so-called
"top hat" letter notice by the Company shall


                                       11


<PAGE>



not be construed or interpreted as an admission on the part of the Company that
this Agreement constitutes an ERISA plan, and the Company hereby categorically
states, and the Employee hereby agrees, that this Agreement is an ad hoc
individual contract with the Employee.

         14. Notices. Any notice required or permitted to be given under this
Agreement shall be sufficient if in writing and sent by first-class, registered
or certified mail or hand-delivered to the Employee at the last residence
address he has provided to the Company or, in the case of the Company, at its
principal Employee offices to the attention of the Corporation Secretary.

         15. Titles and Captions. The section and paragraph titles and captions
contained herein are for convenience only and shall not be held to explain,
modify, amplify, or aid in the interpretation, construction or meaning of the
provisions of this Agreement.

         16. Miscellaneous. This Agreement shall be construed and enforced in
accordance with the laws of the Commonwealth of Massachusetts. In the event that
any provisions of this Agreement shall be held to be invalid, the other
provisions hereof shall remain in full force and effect.

         17. Entire Agreement. The terms of this Agreement are intended by the
parties to be the final expression of their agreement with respect to the
employment of the Employee by the Company and may not be contradicted by
evidence of any prior or contemporaneous oral or written agreement.

                                    ---------

                               STOCK OPTION TERMS

         The Company shall grant to the Employee an option under the Company's
1998 Stock Incentive Plan to purchase up to a number of shares of the Company's
Common Stock which is equivalent to 1% of the issued and outstanding Common
Stock of the Company on a fully-diluted basis as of, and after giving effect to,
the closing of the initial public offering of the Company's Common Stock (the
"IPO") (but not including the exercise, if any, of the over-allotment option
granted to the underwriters in connection with the IPO), which option shall be
conditioned upon the closing of the IPO and shall become exercisable (i) as to
25% of the number of shares subject to such option on the closing of the IPO,
(ii) as to an additional 25% of the number of shares subject to such option as
of the first anniversary of the Effective Date, (iii) an additional 25% of the
number of shares subject to such option on the second anniversary of the
Effective Date, and (iv) an additional 25% of the number of shares subject to
such option on the third anniversary of the Effective Date. This option shall be
evidenced by an Option Agreement on customary terms and conditions (including
the condition that vesting occur only for so long as the Employee is employed by
the Company) and shall be granted under and subject to the terms and conditions
of the Company's 1998 Stock Incentive Plan. This option shall have an exercise
price equal to the price at which the Company's Common Stock is offered to the
public in the IPO. For purposes of this Exhibit A, the "Company" shall mean
FiveCom, Inc. or the successor corporation resulting from the reorganization of
FiveCom, Inc. and its subsidiaries and the reincorporation of FiveCom, Inc. in
Delaware.

                                      -----

         6.1 Term. The term of this Agreement shall begin on the Delivery Date
and shall end at the later of (a) twenty (20) years after the Delivery Date or
(b) the end of the economically useful life of the NEON Fibers as determined by
NEON (the "Term"); subject, however, to the provisions of Section 10.2.

         6.2 Abandonment. In the event that NEON, at any time, reasonably
determines that the NEON Fibers have reached the end of their economically
useful life and desires not to retain the IRU, NEON shall have the right to
abandon the IRU by written notice to QWEST. If, at any time after the last year
of the Minimum Term, NEON fails to use any of the NEON Fibers for any period of
[**] (except to the extent that such non-use is as a result of any of the events
described in Article 20 or as a result of maintenance, restoration, relocation,
or reconfiguration or as a result of the failure of QWEST to observe and perform
the terms of this Agreement), NEON shall be deemed to have determined that the
NEON Fibers have reached the end of their economic life and, accordingly, has
abandoned the NEON Fibers. Upon any such notice of abandonment or acknowledgment
of abandonment, the Term of this Agreement shall expire and all rights to the
New York - Boston Segment and the use of such Segment shall revert to QWEST
without reimbursement of any fees or other payments previously made with respect
thereto, and from and after such time NEON shall have no further rights or
obligations hereunder with respect to such Segment (subject to the provisions of
Articles 12 and 17). The parties acknowledge and agree that so long as this
Agreement is in effect, QWEST shall have no right to abandon the NEON Fibers and
that the determination of economically useful life of the NEON Fibers shall be
in the sole discretion of NEON.

         6.3 Accounting Treatment. It is understood and agreed that the THIRD
PARTY must and does maintain legal title to the entire New York - Boston Segment
subject to the IRU hereunder. Notwithstanding the foregoing, it is understood
and agreed as between the parties that the grant of the IRU hereunder shall be
treated for accounting and federal and all applicable state and local tax
purposes as the sale and purchase of the NEON Fibers, and that on or after the
Acceptance Date with respect to the Segment, NEON shall be treated as the owner
of the NEON Fibers comprising the Segment for such purposes. The parties agree
to file their respective income tax returns, property tax returns, and other
returns and reports for their respective Impositions on such basis and, except
as otherwise required by law, not to take any positions inconsistent therewith.

in selected THIRD PARTY POPs at the fiber distribution panel. All connections
shall be performed by QWEST, at NEON's sole cost and expense, in accordance with
QWEST's applicable specifications and operating procedures. NEON shall pay
QWEST's costs for each such connection within thirty (30) days of the date of
NEON's receipt of QWEST's invoice therefor. NEON shall have no limitations on
the types of electronics or technologies employed to utilize the NEON Fibers,
subject to mutually agreeable safety procedures and so long as such electronics
or technologies do not interfere with the use of or present a risk of damage to
any portion of QWEST's network. QWEST may route the NEON Fibers through QWEST's
separate terminal endlink, POP or Regeneration Facilities at its sole discretion
so long as such routing does not have a material adverse effect on the security,
the safety or NEON's use of the NEON Fibers hereunder and QWEST is responsible
for all costs and expenses associated therewith.

         7.2 Regeneration Facilities. Exhibit E sets forth the sites along the
New York - Boston Segment at which regeneration facilities currently are located
or are be installed in accordance with the Specifications set forth on Exhibit F
which NEON desires to share with QWEST (collectively, the "Regeneration
Facilities"). QWEST agrees to make space available to NEON in Regeneration
Facilities in the amounts and at the prices set forth on Exhibit E attached
hereto. Subject to (a) the availability of space, (b) availability of adequate
and sufficient Underlying Rights, power, and right-of-way access, and (c) the
receipt of all requisite permits, approvals and authorizations, if requested by
NEON, QWEST shall make up to 105 square feet of space available to NEON in
additional regeneration facilities and up to 250 square feet in certain Points
of Presence (POP's) along the route of the Segment for a sum of [**] for
regeneration facilities, and [**] for POP facilities, or, in the alternative,
QWEST will use commercially reasonable efforts to provide shared rack space in
Qwest POPs and/or regeneration facilities at the rate of [**]. All shared

including its proportionate share of any monthly lease costs for any such
facilities and/or underlying property that QWEST leases (including, to the
extent included in such lease costs, base rent, maintenance, insurance, security
and taxes), maintenance of such facilities, and all power and utility fees and
charges. NEON's proportionate share of such operating costs, including a
proportionate share of common area costs, shall be the ratio that the floor
space provided to NEON in any such facility (including a proportionate share of
the common area) bears to (1) in the case of lease costs, the total space in
such facility, and (2) in the case of all other costs (including common area
costs), the total utilized space in such facility. QWEST shall submit invoices
to NEON on an annual basis for NEON's prorata share of such operating costs
during the preceding twelve months. NEON's reimbursement obligations for
insurance and taxes pursuant to this Section 8.2 shall in no event be
duplicative of NEON's payment obligations for insurance or taxes, respectively,
as provided in Article 15 hereof, and in no event shall QWEST be relieved of its
payment obligations for insurance costs or taxes, respectively.

         8.3 Obligations of QWEST. NEON acknowledges and agrees that, except as
expressly provided in Section 7.2, QWEST is not supplying nor is QWEST obligated
to supply to NEON any optronics or electronics or optical or electrical
equipment or other facilities, including, without limitation, generators,
batteries, air conditioners, fire protection and monitoring and testing
equipment, all of which are the sole responsibility of NEON, nor is QWEST
responsible for performing any work other than as specified in this Agreement.

                      PERMITS, REQUIRED RIGHTS; RELOCATIONS
                      -------------------------------------

         10.1 Third Party to Obtain Required Rights. On or before the Delivery
Date with respect to the Segment to be delivered hereunder, QWEST or the THIRD
PARTY shall obtain any right of way agreements, including without limitation,
rights, licenses, authorizations, rights of way, and other agreements necessary
for the use of poles, conduit, cable, wire or other physical plant facilities,
as well as any other such rights, licenses, authorizations (including any
necessary state, tribal or federal authorizations such as environmental
permits), rights of way and other agreements necessary for the installation and
use of the NEON Fibers (all of which are referred to as the "Required Rights")
and, thereafter, will use commercially reasonable efforts to cause the Required
Rights to remain in effect for a minimum term of twenty years (the "Minimum
Period"), and shall use reasonable efforts to enforce the obligation of the
THIRD PARTY to exercise any renewal rights and otherwise use any commercially
reasonable efforts to acquire such extension, additions and/or replacements as
may be necessary in order to cause the term hereof to be continued until a date
that is not earlier than the last day of the Minimum Period. To the extent QWEST
has rights of action against the THIRD PARTY which it elects not to exercise,
QWEST agrees to assign such rights to NEON.

         10.2 Expiration of Required Rights. Upon the expiration or termination
of any Required Right that is necessary in order to grant, continue or maintain
the IRU granted hereunder (as well as other IRUs in the Cable in the New York -
Boston Segment) in accordance with the terms and conditions hereof, and so long
as QWEST shall have fully observed and performed its obligations under this
Article 10 with respect thereto, the Term of the IRU hereunder with respect to
the Segment shall automatically expire upon such expiration or termination of
the Required Right.

         10.3 Relocation. If, after the Delivery Date with respect to the
Segment, the THIRD PARTY or QWEST reasonably determines that it is in the best
interest of all the users of the Cable, or is required by a third party with
legal authority to so require (including, without limitation, the grantor of a
Required Right), or if NEON agrees to relocate any portion of the Segment,
including any of the facilities used or required in providing the IRU in such
Segment hereunder, QWEST or the THIRD PARTY, as applicable, shall proceed with
such relocation, and shall have the right, in good faith, to reasonably
determine the extent of, the timing of, and methods to be used for such
relocation; provided that (a) any such relocation shall be constructed and
tested in accordance with the specifications and drawings set forth in Exhibits
B and C, and incorporate fiber meeting the specifications set forth in Exhibit D
and (b) if the relocation is at QWEST's or the THIRD PARTY's determination, it
shall not adversely affect the operations, performance, connection points with
NEON's network or endpoints of the Segment. In the event of a relocation, and if
so requested by NEON, QWEST will use reasonable efforts to make alternative
fiber or capacity on QWEST's system available to NEON on a temporary basis, at a
reasonable cost.

<PAGE>



         10.4 Relocation Cost Sharing. Unless QWEST is reimbursed by a third
party (which does not have an interest in the fibers in the cable), and provided
that costs of relocation are being shared by all users of the Cable on the
Segment, NEON shall reimburse QWEST or the THIRD PARTY, as appropriate, for its
proportionate share of all costs of such relocation, including without
limitation conduit relocation, fiber acquisition, splicing and testing, of the
portion of the Segment based on the proportion of the NEON Fibers to the total
fibers in the Cable.

                        USE OF NEW YORK - BOSTON SEGMENT
                        --------------------------------

         11.1 Compliance with Required Rights. The requirements, restrictions,
and/or limitations upon NEON's right to use the NEON Fibers as provided and
permitted under this Agreement imposed under, and associated safety, operational
and other rules and regulations imposed in connection with, the Required Rights
are referred to collectively as the "Required Rights Requirements." NEON
acknowledges and agrees that it has performed all due diligence which it deems
necessary and further acknowledges and agrees that subject to the obligations
set forth in Section 10.1, it is taking its IRU on an "as is, where is" basis
and that it is receiving the interests in such IRU Fibers as set forth in this
Agreement only to the extent such interests are held by the conveying party.

         11.2 Use of NEON Fibers. NEON represents, warrants and covenants that
it will use the NEON Fibers in compliance with and subject to the Required
Rights Requirements (to the extent provided to NEON as identified on Exhibit H)
and all applicable government codes, ordinances, laws, rules and regulations.

         11.3 Rights to Install Equipment. The IRU granted hereunder shall
include the right at NEON's cost to install additional equipment, or replace
existing equipment, in the facility space provided to NEON pursuant to Article
7, subject to the provisions of Article 7 and the Required Rights Requirements.

         11.4 QWEST's Rights in Segment. QWEST agrees and acknowledges that it
has no right to use the NEON Fibers during the Term hereof, and that, from and
after the effective date of the grant of each IRU hereunder, QWEST shall keep
the NEON Fibers and NEON's IRU granted hereunder free from (a) any liens of any
third party attributable to QWEST, and (b) any rights or claims of any third
party attributable to QWEST, as and to the extent required pursuant to Article
10 hereof. As provided in the previous sentence, QWEST shall obtain from any
entity in favor of which QWEST in its discretion shall have granted after the
date hereof a security interest or lien on all or part of the Segment a written
nondisturbance agreement substantially to the effect that such lienholder
acknowledges NEON's rights and interests in and to the NEON Fibers and the IRU
hereunder and agrees that the same shall not be diminished, disturbed, impaired
or interfered with in any adverse respect by such lienholder.

<PAGE>



         11.5 Use for Lawful Purposes. Subject to the provisions of Article 22
and this Article 11, NEON may use the NEON Fibers and the IRU for any lawful
telecommunications purpose. NEON agrees and acknowledges that it has no right to
use any of the fibers, other than the NEON Fibers, included in the cable or
otherwise incorporated in the New York - Boston Segment, and that NEON shall
keep any and all of the New York - Boston Segment, other than the IRU granted to
NEON in the NEON Fibers free from any liens, rights or claims of any third party
attributable to NEON.

         11.6 Notification of Damage to Segment. NEON and QWEST shall promptly
notify each other of any matters pertaining to, or the occurrence (or impending
occurrence) of any event which would be reasonably likely to give rise to any
damage or impending damage to or loss of the New York - Boston Segment that are
known to such party.

         11.7 No Adverse Impact. NEON shall not use the NEON Fibers in a way
which physically interferes in any way with or adversely affects the use of the
fibers or cable of any other person using the New York - Boston Segment. QWEST
shall not use any other fibers in the New York - Boston Segment in a way which
physically interferes with or adversely affects the use of the NEON Fibers.

         11.8 Compliance with Regulations. NEON and QWEST each agree to
cooperate with and support the other in complying with any requirements
applicable to their respective rights and obligations hereunder by any
governmental or regulatory agency or authority.

         11.9 Recording. QWEST agrees, so long as any such action would not
violate the terms of any Required Right, upon request of NEON, to execute, file
and/or record such documents or instruments as NEON shall deem reasonably
necessary or appropriate to evidence or safeguard the IRUs granted to NEON
hereunder. NEON agrees to reimburse QWEST for all reasonable costs and
out-of-pocket expenses (including, without limitation, reasonable fees and
expenses of legal counsel directly related to the filing) incurred by QWEST in
fulfilling its obligations under this Section 11.9.

                                 INDEMNIFICATION
                                 ---------------

         12.1 Indemnification by QWEST. Subject to the provisions of Articles 13
and 18, QWEST hereby agrees to indemnify, defend, protect and hold harmless NEON
and its employees, officers and directors, from and against, and assumes
liability for:

                  (a) Any injury, loss or damage to any person (including NEON),
tangible property or facilities of any person or entity (including reasonable
attorneys' fees and costs) to the extent arising out of or resulting from the
acts or omissions, negligent or otherwise, of QWEST, its officers, employees,
servants, affiliates, agents, contractors, or licensees arising out of or in
connection with a default (other than a default caused by a failure of NEON to
perform or comply with its obligations hereunder) by QWEST in the performance of
its obligations or breach of its representations under this Agreement; and

                  (b) Any claims, liabilities or damages, including reasonable
attorneys' fees and costs, arising out of any violation by QWEST of any
regulation, rule, statute or court order of any local, state or federal
governmental agency, court or body in connection with the performance of its
obligations under this Agreement.

         12.2 Indemnification by NEON. Subject to the provisions of Articles 13
and 18, NEON hereby agrees to indemnify, defend, protect and hold harmless
QWEST, and its employees, officers and directors, from and against, and assumes
liability for:

                  (a) Any injury, loss or damage to any person (including
QWEST), tangible property or facilities of any person or entity (including
reasonable attorneys' fees and costs) to the extent arising out of or resulting
from the acts or omissions, negligent or otherwise, of NEON, its officers,
employees, servants, affiliates, agents, contractors, licensees, invitees or
vendors arising out of or in connection with a default (other than a default
caused by a failure of QWEST to perform or comply with its obligations
hereunder) by NEON in the performance of its obligations or breach of its
representations under this Agreement; and

                  (b) Any claims, liabilities or damages, including reasonable
attorneys' fees and costs, arising out of any violation by NEON of any
regulation, rule, statute or court order of any local, state or federal
governmental agency, court or body in connection with its use of the IRU and/or
the NEON Fibers and Associated Property hereunder.

         12.3 Remedy for Failure to Indemnify. The parties hereby expressly
recognize and agree that each party's said obligation to indemnify, defend,
protect and save the other harmless is not a material obligation to the
continuing performance of the parties' other obligations, if any, hereunder. In
the event that a party shall fail for any reason to so indemnify, defend,
protect and save the other harmless, the injured party hereby expressly
recognizes that its sole remedy in such event shall be to seek a remedy under
Article 21 against the other party for its damages as a result of the other
party's failure to indemnify, defend, protect and save harmless. The obligations
of the parties under this Article 12 shall survive the expiration or termination
of this Agreement.

         12.4 Claims Against Third Parties. Nothing contained herein shall
operate as a limitation on the right of either party hereto to bring an action
for damages against any third party, including indirect, special or
consequential damages, based on any acts or omissions of such third party as
such acts or omissions may affect the operation or use of the NEON Fibers or the
QWEST network, except as may be limited by Required Rights Requirements;
provided, however, that each party hereto shall assign such rights or claims,
execute such documents and do whatever else may be reasonably necessary to
enable the other party to pursue any such action against such third party.

                             -----------------------

         13.1 Limitation of Liability. Notwithstanding any provision of this
Agreement to the contrary, neither party shall be liable to the other party for
any special, incidental, indirect, punitive or consequential damages, whether
foreseeable or not, arising out of, or in connection with such party's failure
to perform its respective obligations or breach of its respective
representations hereunder, including, but not limited to, damage or loss of
property or equipment, loss of profits or revenue, cost of capital, cost of
replacement services (whether arising out of transmission interruptions or
problems, any interruption or degradation of service or otherwise), or claims of
customers, in each case whether occasioned by any construction, reconstruction,
relocation, repair or maintenance performed by, or failed to be performed by,
the other party or any other cause whatsoever, including breach of contract,
breach of warranty, negligence, or strict liability, all claims with respect to
which such special, incidental, indirect, punitive or consequential damages are
hereby specifically waived.

                                    ---------

         14.1 Insurance Limits. Following the Delivery Date with respect to the
Segment, and throughout the Term of the IRU with respect to the Segment, each
party shall procure and maintain in force, at its own expense:

                  (a) not less than [**] combined single limit liability
insurance, on an occurrence basis, for personal injury and property damage,
including, without limitation, injury or damage arising from the operation of
vehicles or equipment and liability for completed operations;

                  (b) workers' compensation insurance in amounts required by
applicable law and employers' liability insurance with a limit of at least [**]
per occurrence; and

                  (c) automobile liability insurance covering death or injury to
any person or persons, or damage to property arising from the operation of
vehicles or equipment, with limits of not less than [**] per occurrence; and

         14.2 Self-Insurance; Claims Made Provisions. Both parties expressly
acknowledge that a party shall be deemed to be in compliance with the provisions
of this Article 14 if it maintains an approved self-insurance program providing
for a retention of up to [**]. If either party provides any of the foregoing
coverages on a claims-made basis, such policy or policies shall be for at least
a three-year extended reporting or discovery period. Unless otherwise agreed,
NEON's and QWEST's insurance policies shall be obtained and maintained with
companies rated "A" or better by Best's Key Rating Guide and each party shall
provide the other with an insurance certificate confirming compliance with this
requirement for each policy providing such required coverage.

         14.3 Indemnification for Failure to Comply. In the event either party
fails to obtain the required insurance and a claim is made or suffered, such
party shall indemnify and hold harmless the other party from any and all claims
for which the required insurance would have provided coverage. Further, in the
event of any such failure which continues after seven (7) days' written notice
thereof by the other party, such other party may, but shall not be obligated to,
obtain such insurance and will have the right to be reimbursed for the cost of
such insurance by the party failing to obtain such insurance.

         14.4 Disputes. In the event coverage is denied or reimbursement of a
properly presented claim is disputed by the carrier for insurance provided
above, the party carrying such coverage shall make good-faith efforts to pursue
such claim with its carrier.

         14.5 Waiver of Subrogation. NEON shall obtain from the insurance
companies providing the coverages required by this Agreement the permission of
such insurers to allow NEON to waive all rights of subrogation and NEON does
hereby waive all rights of said insurance companies to subrogation against
QWEST, its parent corporation, affiliates, subsidiaries, assignees, officers,
directors, and employees or any other party entitled to indemnity under this
Agreement.

                 ----------------------------------------------

         15.1 Taxes, Fees and Other Governmental Impositions. The parties
acknowledge and agree that it is their mutual objective and intent to (a)
minimize, to the extent feasible, the aggregate Impositions payable with respect
to the New York - Boston Segment and (b) share such Impositions according to
their respective interests in the New York - Boston Segment, and that they will
cooperate with each other and coordinate their mutual efforts to achieve such
objectives in accordance with the provisions of this Article 15. It is
understood and agreed as between the parties that the grant of the IRU in the
NEON Fibers shall be treated for accounting and federal and all applicable state
and local tax purposes as the sale and purchase of the NEON Fibers and that on
or after the Acceptance Date, NEON shall be treated as the owner of the NEON
Fibers for such purposes. The parties agree to file their respective income tax
returns, property tax returns, and other returns and reports for their
respective Impositions on such basis and except as otherwise required by law,
not to take any positions inconsistent therewith.

                                     -------

         18.1 NEON's Default. With respect to all payments required to be made
by NEON hereunder, including, without limitation, payment of the IRU Fee and all
other amounts payable by NEON hereunder, if NEON fails to make a payment by the
date due and payable hereunder, from and after such date, (a) such unpaid amount
shall bear accrued interest compounded monthly until paid at an annual rate
equal to [**] of the prime rate of interest published by the Wall Street Journal
the date any such payment is due or, if lower, the highest percentage allowed by
law and (b) if such payment is due with respect to the Segment on or prior to
the Delivery Date of the Segment, the Estimated Delivery Date for the Segment
shall be extended by a number of days equal to the number of days that elapse
from the date such payment is due until paid. In the event any amount or amounts
due and payable hereunder remain unpaid for a period of thirty (30) days after
written notice from QWEST to NEON, then QWEST may, in its sole and absolute
discretion and in addition to its other rights and remedies hereunder, terminate
any and all of its obligations hereunder with respect to the Segment, and to
apply any and all amounts previously paid by NEON hereunder with respect to the
Segment toward the payment of any other amounts then or thereafter payable by
NEON hereunder.

                  With respect to all of its other obligations hereunder, if
NEON fails to perform a nonpayment obligation and such failure shall continue
for a period of [**] after receipt by NEON of written notice of such failure,
NEON shall be in default hereunder unless NEON shall have cured such failure or
such failure is otherwise waived in writing by QWEST within such [**] provided,
however, that where such failure cannot reasonably be cured within such [**], if
NEON shall proceed promptly to cure the same and prosecute such cure with due
diligence, the time for curing such failure shall be extended for such period of
time as may be necessary to complete such cure; and provided further that if
NEON certifies in good faith to QWEST in writing that a non-payment failure has
been cured, such failure shall be deemed to be cured unless QWEST otherwise
notifies NEON in writing within [**] of receipt of such notice from NEON.

default by NEON, after written notice thereof from QWEST, QWEST may (a) take
such action as it determines, in its sole discretion, to be necessary to correct
the default and, subject to Section 13.1, recover from NEON its reasonable costs
incurred in correcting such default, and (b) pursue any legal remedies it may
have under applicable law or principles of equity relating to such default,
including specific performance.

         18.2 QWEST's Default. With respect to its obligation to complete the
construction, installation and satisfactory Fiber Acceptance Testing by the
Estimated Delivery Date, QWEST shall be in default under this Agreement if the
Delivery Date has not occurred within [**] after the Estimated Delivery Date
(the "Delivery Default Date"). In addition, in the event a force majeure event
or occurrence described in Article 20 causes an extension of the Estimated
Delivery Date and such event or occurrence has not been terminated, avoided or
resolved by the date that is [**] following the Delivery Default Date, NEON may
elect, in its sole discretion, by written notice to QWEST, to terminate this
Agreement and recover from QWEST the amount of the IRU Fee previously paid by
NEON hereunder with respect to the Segment. Upon any such election and payment,
neither party shall have any further rights or obligations.

                  With respect to QWEST's other obligations hereunder, in the
event that QWEST shall fail to perform an obligation and such failure shall
continue for a period of [**] after NEON shall have given QWEST written notice
of such failure, QWEST shall be in default hereunder unless QWEST shall have
cured such failure or such failure is otherwise waived in writing by NEON within
such [**]; provided however, that where such failure cannot reasonably be cured
within such [**], if QWEST shall proceed promptly to cure the same and prosecute
such cure with due diligence, the time for curing such failure shall be extended
for such period of time as may be necessary to complete such cure; and provided
further, that if QWEST certifies in good faith to NEON in writing that failure
has been cured, such failure shall be deemed to be cured unless NEON otherwise
notifies QWEST in writing within fifteen (15) days of receipt of such notice
from QWEST.

                  QWEST shall be in default hereunder (a) automatically upon the
making by QWEST of a general assignment for the benefit of its creditors, the
filing by QWEST of a voluntary petition in bankruptcy or the filing by QWEST of

                                   -----------

         19.1 Expiration of Term. This Agreement automatically shall terminate
with respect to a Segment upon the expiration or termination of the Term of the
IRU respecting the Segment pursuant to Article 6.

         19.2 Removal of Electronics. Upon the expiration or termination of this
Agreement , the IRU shall immediately terminate and all rights of NEON to use
the Segment, the NEON Fibers, the associated property or any part thereof
relating to the Segment, shall cease and QWEST shall owe NEON no additional
duties or consideration with respect to the Segment. Promptly thereupon, NEON
shall remove all of NEON's electronics, equipment, and other NEON property from
such Segment and any related QWEST facilities at its sole cost, under QWEST's
supervision (which supervision shall be without cost to NEON).

         19.3 Survival of Obligations. Notwithstanding the foregoing, no
termination or expiration of this Agreement shall affect the rights or
obligations of any party hereto (a) with respect to any then existing defaults

13, Article 15 or Article 17 herein, which shall survive the expiration or

         20.1 Force Majeure. Neither party shall be in default under this
Agreement if and to the extent that any failure or delay in such party's
performance of one or more of its obligations hereunder is caused by any of the
following conditions, and such party's performance of such obligation or
obligations shall be excused and extended for and during the period of any such
delay: act of God; fire; flood; fiber, Cable, or other material shortages or
unavailability or other delay in delivery not resulting from the responsible
party's failure to timely place orders therefor (it being expressly acknowledged
that the Cable that is being acquired for and installed in the New York - Boston
Segment and that will include the NEON Fibers must include higher fiber counts
than that necessary solely for the NEON Fibers in order to permit completion of
the entire New York - Boston Segment); lack of or delay in transportation;
government codes, ordinances, laws, rules, regulations or restrictions; war or
civil disorder; strikes or other labor disputes; failure of a third party to
grant or recognize the Required Rights (provided that QWEST has made timely and
reasonable commercial efforts to obtain the same), or any other cause beyond the
reasonable control of such party. The party claiming relief under this Article
shall notify the other in writing of the existence of the event relied on and
the cessation or termination of said event, and the party claiming relief shall
exercise reasonable commercial efforts to minimize the time of any such delay.

                               ------------------

         21.1 Arbitration. Except as provided in Sections 18.1 and 18.2, if the
parties are unable to resolve any disagreement or dispute arising under or
related to this Agreement, including without limitation, the failure to agree
upon any item requiring a mutual agreement of the parties hereunder, they shall
resolve the disagreement or dispute by arbitration as prescribed in this
Section. The Federal Arbitration Act, 9 U.S.C. Sections 1-15, not state law,
shall govern the arbitrability of all claims.

         21.2 Appointment of Single Arbitrator. A single arbitrator engaged in
the practice of law who is knowledgeable about the subject matter of this
Agreement shall conduct the arbitration under the then current rules of the
American Arbitration Association (the "AAA"). The arbitrator shall be selected
in accordance with AAA procedures from a list of qualified people maintained by
the AAA. The arbitration shall be conducted in the regional AAA office in
Denver, Colorado if the arbitration is initiated by NEON and in Boston,
Massachusetts if initiated by QWEST, and all expedited procedures prescribed by
the AAA rules shall apply.

         21.3 Discovery. There shall be no discovery other than the exchange of
information which is provided to the arbitrator by the parties. The arbitrator
shall have authority only to award compensatory damages and shall not have
authority to award punitive damages, other noncompensatory damages or any other
form of relief; the parties hereby waive all rights to any claims for relief
other than compensatory damages. The arbitrators' fees and other costs of the
arbitration shall be borne by the party against whom the award is rendered,
except as the arbitrator may otherwise provide in a written opinion.

         21.4 Binding of Successors. If any party files a judicial or
administrative action asserting claims subject to arbitration as prescribed
herein, and another party successfully stays such action or compels arbitration
of said claims, the party filing said action shall pay the other party's costs
and expenses incurred in seeking such stay or compelling arbitration, including
reasonable attorneys' fees.

or affiliate of QWEST, (3) to any person, firm or corporation which shall

or which purchases all or substantially all of the stock or assets of QWEST;

to be subject to all of the provisions of this Agreement, including without
limitation, this Section 22.1 (except that any lender referred to in clause (b)
(1) above shall not incur any obligations under this Agreement nor shall it be
restricted from exercising any right of enforcement or foreclosure with respect
to any related security interest or lien, so long as the purchaser in
foreclosure is subject to the provisions of this Agreement, including, without
limitation, this Section 22.1); and provided further that promptly following any
such assignment or transfer, QWEST shall give NEON written notice identifying
the assignee or transferee. In the event of any permitted partial assignment of
any rights hereunder, QWEST shall remain the sole point of contact with NEON. No
permitted partial or complete assignment shall release or discharge QWEST from
its duties and obligations hereunder.

         22.2 Assignment by NEON. Except as provided in this Section 22.2 and

collateral to any lender to NEON (or lender to any permitted transferee or
assignee of NEON) subject to the prior rights and obligations of the parties
hereunder, (b) to any parent, subsidiary or affiliate of NEON, (c) to any
person, firm or corporation which shall control, be under the control of or be
under common control with NEON, or (d) any other entity into which NEON may be

or assets of NEON; provided that the assignee or transferee in any such
circumstance shall continue to be subject to all of the provisions of this
Agreement, including without limitation this Section 22.2 and the following
Section 22.3 (except that any lender referred to in clause (a) above shall not
incur any obligations under this Agreement, nor shall it be restricted from
exercising any right of enforcement or foreclosure with respect to any related
security interest or lien, so long as the purchaser in foreclosure is subject to
the provisions of this Agreement, including, without limitation, this Section
22.2 and the following Section 22.3); and provided further that in any of
circumstances described in clauses (b), (c) or (d) all of the payment
obligations of NEON hereunder for the remainder of the Term shall be paid in
full as a condition to such transfer or assignment; and provided further that
promptly following any such assignment or transfer, NEON shall give QWEST
written notice identifying the assignee or transferee. In the event of any
permitted partial assignment of any rights hereunder, NEON shall remain the sole
party and point of contact with QWEST hereunder. No permitted partial or
complete assignment shall release or discharge NEON from its duties and
obligations hereunder.

         22.3 Restriction on Transfer of Dark Fiber. Notwithstanding the

any manner transfer or make available in any manner to any third party the
ownership, right to use, or use of, or access in any manner to, any of NEON's
rights in the whole and discrete NEON Fibers as Dark Fibers (any of the
foregoing, a "Restricted Transaction") (or engage in substantive discussions or
negotiations with respect to a Restricted Transaction), or otherwise engage in a
similar transaction with respect to any NEON Fibers comprising the Segment in a
manner designed or intended to circumvent the foregoing limitations. Nothing in
this Agreement will preclude NEON from assigning, leasing or granting capacity
in its lit Fiber in the ordinary course of business.

         22.4 Binding on Successors. This Agreement and each of the parties'
respective rights and obligations under this Agreement, shall be binding upon

         23.1 Representations of Both Parties. Each party represents and
warrants that:

                  (a) it has the full right and authority to enter into,
execute,  deliver and perform its obligations under this Agreement;

                  (b) this Agreement constitutes a legal, valid and binding
obligation enforceable against such party in accordance with its terms, subject
to bankruptcy, insolvency, creditors' rights and general equitable principles;
and

                  (c) its execution of and performance under this Agreement
shall not violate any applicable existing regulations, rules, statutes or court
orders of any local, state or federal government agency, court or body.

         23.2 Permitted Grant. Qwest represents and warrants that the terms of
its Agreement with the THIRD PARTY specifically provide that Qwest may grant an
IRU in its dark fibers to a third party and, further, that it has reviewed
certain of the Required Rights documents and has found nothing to preclude the
assignment of its fibers to NEON.

         23.3 Construction of Segment. QWEST represents and warrants that the
Segment shall be constructed by the THIRD PARTY substantially and in all
material respects in accordance with the specifications set forth in Exhibit B
hereto; provided that NEON's sole rights and remedies with respect to any
failure to so construct shall be to inspect the construction, installation and
splicing, and participate in the acceptance testing, of the NEON Fibers
incorporated in each such Segment, during the course and at the time of the
relevant construction, installation and testing periods for the Segment, as
provided in Articles 3 and 4; provided, however, that to the extent QWEST has
rights of action against the THIRD PARTY which it elects not to exercise, QWEST
agrees to assign such rights to NEON.

         23.4 No Additional Warranties. EXCEPT AS SET FORTH IN THE FOREGOING
PARAGRAPHS 23.2, and 23.3 OR AS OTHERWISE IN THIS AGREEMENT QWEST MAKES NO
WARRANTY, EXPRESS OR IMPLIED, WITH RESPECT TO THE NEON FIBERS DELIVERABLE
HEREUNDER, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR PARTICULAR
PURPOSE, AND ALL SUCH WARRANTIES ARE HEREBY EXPRESSLY DISCLAIMED.

         23.5 Assignment of Vendor Warranties. The parties acknowledge and agree
that on and after the Acceptance Date NEON's sole rights and remedies with
respect to any defect in or failure of the NEON Fibers to perform in accordance
with the applicable vendor's or manufacturer's specifications with respect to
the NEON Fibers shall be limited to the particular vendor's or manufacturer's
warranty with respect thereto, which warranty, to the extent permitted by the
terms thereof, shall be assigned to NEON upon its request. In the event any
maintenance or repairs to the New York - Boston Segment are required as a result
of a breach of any warranty made by any manufacturers, contractors or vendors,
unless NEON shall elect to pursue such remedies itself, QWEST may, at its cost,
pursue all remedies against such manufacturers, contractors or vendors on behalf
of NEON, and QWEST shall reimburse NEON's costs for any maintenance NEON has
incurred as a result of any such breach of warranty to the extent the
manufacturer, contractor or vendor has paid such costs.

                                     GENERAL
                                     -------

         24.1 Waiver. The failure of either party hereto to enforce any of the
provisions of this Agreement, or the waiver thereof in any instance, shall not
be construed as a general waiver or relinquishment on its part of any such
provision, but the same shall nevertheless be and remain in full force and
effect.

         24.2 Governing Law. This Agreement shall be governed by and construed
in accordance with the domestic laws of the State of Colorado, without reference
to its choice of law principles. Any litigation based hereon, or arising out of
or in connection with a default by either party in the performance of its
obligations hereunder, shall be brought and maintained in the courts of the
State of Colorado or in the United States District Court in Denver, Colorado, if
brought by NEON and in the courts of the State of Massachusetts or this United
States District Court in Boston, Massachusetts if brought by QWEST, and each
party hereby irrevocable submits to the jurisdiction of such courts for the
purpose of any such litigation and irrevocably agrees to be bound by any
judgment rendered thereby in connection with such litigation.

                            Supports All Wavelengths
                          for Nonzero-Dispersion Fiber

Lucent Technologies award winning TrueWave single-mode optical fiber meets the
needs of today's and tomorrow's high performance optical networks. This patented
fiber is the first fiber specifically designed for optically amplified high
capacity single wavelength and multiple wavelength transport systems. High
capacity systems include Dense Wavelength Division Multiplexing (DWDM)
technology where 8, 16 or more wavelengths within the Erbium Doped Fiber
Amplifier band (EDFA) are combined and transmitted over one single-mode fiber.
High capacity is also achieved with Time Division Multiplexing (TDM) technology,
where the bit rate of each channel is increased to 10 Gb/s or greater.

In designing your current networks, you need to be sure that the fiber chosen
today will support capacity expansion possibilities in the future. The direction
of these future systems will include combinations of even more wavelengths,
higher bit rates and all optical networks. With TrueWave fiber, you can be
assured that your cable system will be futureproof. TrueWave is the fiber of
choice for long haul networks, and becoming a preferred fiber for regional
networks.

Broad Wavelength Capability

TrueWave fiber's wide nonzero-dispersion region complements amplifier
improvements and emerging wavelength standards to give increased upgrade options
in wavelength selection. The minimum dispersion over the 1530 to 1565 nm
wavelength range supports future systems having higher bit rates and more
closely-spaced wavelength channels.

Flexible
Optoelectronic
Choices

Because TrueWave fiber supports wavelengths over the full 1530 to 1565 nm
wavelength range defined by standards bodies, the fiber can be used with
transmission equipment from many vendors. TrueWave fiber is also compatible
with other single-mode fiber types, allowing the same installation and splicing
techniques to be used. 

Reduce Signal
Interference With
TrueWave Fiber

Although dispersion-shifted fibers have been used for some amplified 1550 nm
systems, their ability to support DWDM in the EDFA wavelength band is severely
limited by nonlinear fiber effects, such as four-wave mixing. TrueWave fiber
overcomes this problem by providing a small amount of chromatic dispersion
throughout the EDFA band. 

This dispersion prevents phase matching between the various signal wavelengths,
virtually eliminating the four-wave mixing interference effects. The dispersion
value is still small enough to allow 10 Gb/s data rates at each of multiple
wavelengths over long distances. 

Reduce System
Cost With
TrueWave Fiber

Dispersion unshifted (conventional) fiber was designed to minimize loss and
maximize bandwidth for 1310 nm systems. The high chromatic dispersion at 1550 nm
(approximately 17 ps/nm-km) may require the additional cost of dispersion
compensation and/or more transmission equipment to use this fiber in high
capacity amplified systems. 

TrueWave fiber uses a special refractive index profile in the core, surrounded
by synthetic silica cladding layers having different refractive indices, to
achieve low attenuation and small, nonzero-dispersion in the EDFA operating
region. This reduces or even eliminates the cost of dispersion compensation.
Manufactured using a patented fiber drawing process, TrueWave fiber also has
exceptionally low and stable Polarization Mode Dispersion (PMD) which ensures
excellent performance in even the most demanding future applications.

                                    EXHIBIT G



The party responsible for providing maintenance for a Cable System shall be
referred to herein as the Service Provider ("SP"), and the party responsible for
receiving maintenance for a Route shall be referred to herein as the Service
Recipient ("SR"). All other capitalized terms are defined in Attachment 1.

1.       Maintenance Activities

The following subsections of this outline describe the types of Maintenance
Activities that must be performed. All Maintenance Activity types described
below shall be performed by or under the direction of the SP.

For all Maintenance Activities, SR may contact SP at any time to discuss or
notify fiber status, fiber problems, or any other fiber issues or anomalies for
SR's fibers on SP's Cable System. However, no other party, including but not
limited to a Lessee of the SR's fibers, shall call the SP for anything related
to SR's fibers without the written agreement of both the SR's and SP's
escalation list's Tier 5 representative. It is the intention of the Agreement
that any lessee of the SR's fibers shall coordinate all problems and issues
solely with the SR.

Parties have the right to review each other's maintenance standards, which
include preventative maintenance procedures, Planned Cable Activity procedures,
and cable restoration procedures.

SP shall notify SR at least [**] prior to the date in connection with any
Planned System Work Period (PSWP) of any Maintenance Activity and as soon as
possible after becoming aware of the need for unscheduled maintenance. SR shall
have the right to be present during the performance of any Maintenance Activity
or unscheduled maintenance so long as this requirement does not interfere with
SP's ability to perform its obligations under this Agreement. In the event that
Maintenance Activity is canceled or delayed for whatever reason as previously
notified, SP shall notify SR at SP's earliest opportunity, and will comply with
the provisions of the previous sentence to reschedule any delayed activity.

         1.1.     Preventative Maintenance

Preventative maintenance will be performed according to the SP's standards. Each
SP's maintenance standards must include the following:

                                    EXHIBIT G

                  1.1.1.   Cable Damage Prevention

The SP will subscribe to each and all One-Call Agencies that affect the SR's
route(s). In addition, the SP will abide by all state One-Call Agency laws and
respond to all locate requests.

                  1.1.2.   Patrolling

Patrol of SP's route shall be conducted in accordance with the then current SP's
procedures for maintenance.

                  1.1.3.   Signs

SP shall maintain sign posts along the ROW that affect SR's route(s). All sign
posts shall include the phone number of the local One-Call Agency and the SP's
"800-" phone number. Markers should be placed [**] land use permitting. Markers
should always be placed [**]. Placing of markers in cultivated areas or at
locations likely to be objectionable to property owners should be avoided.

                  1.1.4.   Voltage Suppressor/Arrestor

Wherever the cable sheath voltage [**].

         1.2.     Planned Cable Activity

A Planned Cable Activity (PCA) is any activity which can be planned in advance
(i.e., not an emergency) that will cause maintenance personnel to physically
move the cable, or will affect the sheath and/or the fiber. There are two types
of PCAs: intrusive and non-intrusive.

                  1.2.1.   Intrusive PCAs

An intrusive PCA is any PCA that the SP will expose the buffer tube and/or the
fibers. Examples of intrusive PCAs are as follows: 
o installation of insulating joints / isolation closures, 
o reroutes / cutovers / hot cuts, 
o repairing damaged fibers at splice locations,

o repairing sheath faults.
Intrusive PCAs [**]. If exceptions are required to these times, refer to the
escalation list.

                  1.2.2.   Non-Intrusive PCAs

Examples of non-intrusive PCAs are as follows:
o cable lowering, cable rearrangements
o conduit or manhole rearrangements
Non-intrusive PCAs can be performed anytime.

                  1.2.3.   Responsibilities of SP and SR

For all PCAs, the SP must notify the SR at least [**] prior to the activity.

For PCA activity that will result in signal discontinuity, the following process
will be performed:

o  At least [**] in advance: SP shall provide a copy of their Method of
   Procedure (MOP) in writing to SR, and will notify SR of this PCA per
   escalation list.
o  At least [**] in advance: After receipt of SP's MOP, SR then will provide a
   copy of their MOP to the SP that incorporates the switching, verification,

         1.3.     Cable Restoration

A cable restoration occurs whenever service has affected one or more fibers and
restoration of the fiber(s) is needed. The fiber(s) may or may not have service
on them.

The SP will respond to all SR's notifications indicating any failure, any
interruption, or any impairment to the SR's Cable System.

There are two (2) types of cable restorations as follows:

                  1.3.1.   Types of Restorations

                           1.3.1.1. Total Cable Cut

A total cable cut occurs when ALL fibers in the cable sheath are affected.

The SP shall notify SR of the cable cut, per escalation list, including the time
of the cable cut, and the regenerator section as soon as possible, but no later
than [**]. Once this information is provided to the SR, the SP shall establish a
communications bridge with the SR to stay in constant communication throughout
the cable cut.

In the event the SP's fibers are not lit (no equipment on the fibers), the SR
shall notify the SP of such event.

The SP shall notify the SR of the physical location of the cable cut as soon as
possible but no later than [**].

SP will determine the restoration sequence of specific damaged fibers, by
city-pair Segment, in a predetermined customer rotational sequence.

[**]. The only exception to this cable restoration time is when an uncontrolled
incident, such as a flood, a chemical spill, a fire, a bridge collapse, a riot,
or other circumstance prevents access to the damage area.

To accomplish this cable restoration, it is acknowledged that the repairs so
effected may be temporary in nature. In such event, [**] after completion of all
temporary Restoration activity, SP shall commence its planning for permanent
repair, and thereafter promptly shall notify SR of such plans. If the SP informs
the SR that the temporary fiber repair cannot be made permanent immediately,
then the permanent repair shall be mutually agreed upon by both parties.

The parties agree to mutually support each other during restoration activities.
Examples of support may include providing fault-locating, splicing, or running
errands. All support is at the discretion of the SP.

For all temporary repairs, the SP shall maintain an on-site personnel for all
exposed cables.

Refer to intrusive PCA section to accomplish permanent repairs.

                           1.3.1.2. Partial Cable Cut

A partial cable cut occurs when less than ALL fibers in the cable sheath are
affected.

For partial cable cuts, if and where possible, [**].

The SP shall notify SR of the partial cable cut, per escalation list, including
the time of the cable cut, and the regenerator section as soon as possible, but
[**]. Once this information is provided to the SR, the SP shall establish a
communications bridge with the SR to stay in constant communication throughout
the partial cable cut.

The SP shall notify the SR of the physical location of the cable cut as soon as
possible but no later than [**].

In the event [**].

                                    EXHIBIT G

Restoration prioritization will be the same as that outlined in section 1.3.1.1
total cable cut.

The SP will notify the SR when each fiber has been repaired, and then the SR
will verify that continuity exists from end-to-end on the Cable System for the
fiber.

Verification of continuity of Dark Fibers shall be the responsibility of the SP
or SR depending on whomever has the capability to verify service.

For every partial cable cut, SP shall restore SR's service-carrying fiber in
[**]. The only exception to this cable restoration time is when an uncontrolled
incident, such as a flood, a chemical spill, a fire, a bridge collapse, a riot,
or other circumstance prevents access to the damage area.

To accomplish this partial restoration, it is acknowledged that the repairs so
affected may be temporary in nature. In such event, [**] after completion of all
temporary restoration activity, SP shall commence its planning for permanent
repair, and thereafter promptly shall notify SR of such plans. If the SP informs
the SR that the temporary fiber repair can not be made permanent immediately,
then the permanent repair shall be mutually agreed upon by both parties.

For all temporary repairs, the SP will maintain an on-site personnel for all
exposed cables.

Refer to intrusive PCA section to accomplish permanent repairs.

         1.4.     Hazardous Conditions/Service Precautions

A hazardous condition or service precaution is when an event, such as flooding,
fire, street collapse, cable wash-out or a man-made event such as a train
derailment occurs, and there is an increased probability that the SP's cable may
be damaged, and maintenance activity is needed to prevent any potential damage.

For these events SP shall notify SR, per escalation list, as soon as the SP
knows of such event. The SP shall establish a communications bridge for these
events.

         1.5.     Disaster Recovery

Disaster recovery is any event that affects service on the cable and involves
significantly more maintenance activity than just a cable restoration. Examples
of disaster recovery are as follows:

        Securities and Exchange Commission. Asterisks denote omissions.


                                  Page 9 of 10


                                    EXHIBIT G

         o   train derailment occurs, which by itself would be a hazardous
             condition, but for this example it destroys a regeneration
             site, or
         o   the cable at a bridge is washed out and restoration involves
             deploying several miles of cable to restore service.

For these events SP shall notify SR, per escalation list, as soon as the SP
knows of such event. The SP shall establish a communications bridge for these
events.

The parties agree to mutually support each other during disaster recovery
activities. Examples of support may include providing fault-locating, splicing,
or running errands. All support is at the discretion of the SP.

2.       Operations/Network Control Center(s)

         2.1.     Operations / Network Control Centers

The terms Operations Center and Network Control Center are synonymous, and will
be called Operations Centers for the remainder of this document.

SP shall operate and maintain an Operations Center (OC) staffed [**]. The OC
shall be staffed by trained and qualified personnel. SP's maintenance personnel
shall be available for dispatch [**].

3.       Facilities

Except to the extent otherwise expressly provided in the Agreement, SR will be
solely responsible for providing and paying for any and all maintenance of all
electronic, optical, and any other equipment, materials and facilities used by
SR in connection with the operation of the Dark Fibers, none of which is
included in the maintenance services to be provided hereunder.

Each party agrees that the Facilities shall be placed and maintained in
accordance with the requirements and specifications of current editions of the
National Electrical Code and the National Electrical Safety Code, the applicable
rules and regulations of the Occupational Safety and Health Act (including those
of 29 C.F.R. 1910.268(a) et seq.) and the requirements of any other authority
having jurisdiction. Each party shall promptly furnish to each other, but in no
case later than [**], copies of all notices, reports, correspondence,
submissions, made by either party to federal, state, or municipal environmental,
safety, or health authorities. Each party agrees that Facilities shall not
physically, electronically or inductively interfere with those of facilities in
place.

                           FIBER OPTIC LEASE AGREEMENT


1. PREAMBLE. Effective July 2, 1998, NEES Communications, Inc. ("NEES Com") and
FiveCom, Inc. ("FiveCom") (collectively "Parties," singularly "Party") agree as
follows:

2. BACKGROUND. FiveCom has or is developing a fiber optic system from [**]
("FiveCom System"). To the FiveCom System, FiveCom wishes to add a fiber optic
network ("FiveCom Network") from [**] to a FiveCom Point of Presence ("POP") to
be built at [**]. The [**]. FiveCom, NEES Com, and BecoCom, Inc. ("BecoCom")
wish jointly to build their respective portions of this network under the terms
of separate agreements between FiveCom and NEES Com and between FiveCom and
BecoCom. The purpose of the FiveCom Network is to provide telecommunications
capacity between [**].

The FiveCom Network is described as follows. [**], is to be installed from the
[**] through [**], an underground fiber optic cable, consisting of [**] single
mode fibers, is to be installed. From the FiveCom POP at [**] an underground
fiber optic cable, consisting of [**], is to be installed connecting the [**]
carrier POPs described above, and returning to the [**]. Exhibit 2 depicts the
FiveCom Network.

FiveCom, NEES Com, and BecoCom are each responsible for constructing a portion
of this network. These portions are defined by the following demarcation points:

         FiveCom - NEES Com Demarcation Point: This is defined as the splice box
         to be located on the [**].

         NEES Com - BecoCom Demarcation Point: This is defined as a mid-span
         point located above the town line between [**]. This demarcation occurs
         between Transmission Line [**]. Because this demarcation point is
         mid-span, joint or closely coordinated construction of the NEES Com and
         BecoCom [**] facilities must occur.

         FiveCom - BecoCom Demarcation Points:  The "FiveCom - BecoCom
         Demarcation Point 'A'" is defined as a mutually acceptable location
         along the [**] city line, depending upon the exact route taken for the
         fiber optic cable installed between the FiveCom [**]. The "FiveCom -
         BecoCom Demarcation Point 'B'" is defined as a mutually acceptable
         location along the [**] city line, depending upon the exact route taken
         for the fiber optic cable installed between [**].

          Confidential Materials omitted and filed separately with the
        Securities and Exchange Commission. Asterisks denote omissions.

There will be additional demarcation points at the [**] carrier locations
specified above. At each location, the demarcation point is defined as a splice
box or patch panel installed in a mutually acceptable manner. If approval of the
building owner is required, FiveCom shall be responsible for securing any
necessary co-location rights.

Having established the demarcation points, each Party's portion of the network
can be described as follows:

         NEES Com Portion: A [**] fiber optic cable between the FiveCom - NEES
         Com Demarcation Point and the NEES Com - BecoCom Demarcation Point.

         BecoCom Portion: (a) A [**] fiber optic cable between the NEES Com -
         BecoCom Demarcation Point and the Demarcation Point at the FiveCom POP,
         plus (b) a [**] fiber optic cable from the Demarcation Point at the
         FiveCom POP to the FiveCom - BecoCom Demarcation Point "A," plus (c) a
         [**] fiber optic cable from the Demarcation Point at the FiveCom POP to
         the Demarcation Point at [**] to FiveCom - BecoCom Demarcation Point
         "B."

         FiveCom Portion: The initial optronics component of the FiveCom Portion
         is intended to be sufficient to operate (a) [**], or equivalent,
         between [**], and (b) [**], or equivalent, connecting the [**] carrier
         locations described above. FiveCom shall use its best commercial
         efforts install this optronic equipment within [**] after the
         Completion Date, and shall have some discretion to modify this optronic
         equipment to adjust to business conditions, but shall not eliminate or
         forgo a substantial portion of its capital investment responsibilities
         to install optronic equipment without the approval of NEES Com. FiveCom
         may install additional optronic equipment at its option. The non-
         optronic component of the FiveCom Portion shall consist of (a) a [**]
         fiber optic [**] from the [**] to the FiveCom - NEES Com Demarcation
         Point, plus (b) a [**] fiber optic cable from the FiveCom - BecoCom
         Demarcation Point "A" to [**] to the FiveCom - BecoCom Demarcation
         Point "B" plus (c) any necessary wiring on the Non-Network Side of the
         applicable demarcation points described above.

equivalent amount of the non-optronic portion of the FiveCom Portion as
discussed in Section 4.5 above, or otherwise fails to use its best commercial
efforts to install the optronic portion of the FiveCom Portion as described in
Section 2. If the delay in providing at least [**] fibers continues until [**],
then either Party in its sole discretion shall have the right to terminate this
Agreement, provided that any such termination shall not affect whatever rights
either party had obtained under this Agreement prior to such termination.

         5.3 Testing. The Completion Date shall be deemed to be the date that
NEES Com has installed the Cable called for in Section 4.1 along the NEES Com
Portion of the Route as described in that section and that at least [**]of the
FiveCom Fibers satisfy the Specifications. Satisfaction of the Specifications
shall be established specifically for the NEES Com Portion by testing in
accordance with the Acceptance Test Plan ("ATP") described in Exhibit 5.3. NEES
Com shall provide FiveCom with written notice of the commencement of the
acceptance testing at least [**] prior to that commencement. Subject to the
restrictions, terms and conditions of the Utility Agreement, FiveCom shall have
the right to have representatives present to observe any tests conducted by NEES
Com as part of the ATP. NEES Com shall be responsible for testing the NEES Com
Portion of the FiveCom Network, and FiveCom shall be responsible for testing the
entire FiveCom Network on an end-to-end basis. If the end-to-end test reveals
that a particular piece of equipment (including fiber strands and splices) fails
to satisfy the Specifications, the Party responsible for such installation shall
be responsible for fixing it. The failure of FiveCom to complete satisfactorily
the end-to-end testing of the entire FiveCom Network shall not relieve FiveCom's
obligations to make payment under Section 8, unless the failure is due to a
breach by NEES Com of this Agreement.

         5.4 Review of the Test Results. Within [**] of the conclusion of the
ATP, NEES Com shall provide FiveCom with test results certified by NEES Com in
accordance with the ATP and pursuant to Exhibit 4.2, Item 3.0. If the certified
test results establish that the FiveCom Fibers satisfy the Specifications, and
if FiveCom shall not object to such conclusion within [**] of its receipt of
such results, then the date of the completion of the ATP testing shall be deemed
to be the Completion Date. If FiveCom shall so object, it shall provide to NEES
Com sufficient technical details of its objection within such [**] period. If
NEES Com disagrees with FiveCom's objections, then the dispute shall be
submitted to the neutral expert mutually agreed by the Parties for resolution
within [**], or if the Parties cannot agree on a neutral expert, then the
dispute will be resolved by arbitration pursuant to Section 23. The neutral
expert or arbitration panel, as the case

may be, shall resolve the dispute and determine the Completion Date, including
whether or not any amount is payable pursuant to Sections 8 and 5.2. Use of the
FiveCom Fibers, or any subset thereof, by FiveCom for any purpose other than
testing as provided herein shall constitute acceptance of the fibers so used by
FiveCom, and the Completion Date shall be deemed to have occurred with respect
to such fibers.

         5.5 Completion of Remaining Fibers. In the event that the Completion
Date is declared based on NEES Com's delivery of [**] or more FiveCom Fibers,
but less than all [**] FiveCom Fibers described in Section 4.1, then if
requested by FiveCom, NEES Com shall use commercially reasonable efforts to
ensure that FiveCom has access to capacity equal to [**] fiber optic strands
that meet the Specifications at the earliest practicable date after the
Completion Date.

6.       DELIVERABLES.

         6.1 Description. Within the time periods specified in Section 6.2, NEES
Com shall deliver to FiveCom the items listed in Exhibit 6.1 (the
"Deliverables").

         6.2 Delivery Times. The Deliverables shall be supplied within 60 days
following the Completion Date except for the items listed in Exhibit 6.1 as
being delivered at other specified times. NEES Com shall provide five copies of
all material delivered to FiveCom pursuant to this Section 6.




7.       HABENDUM AND TERM.

         7.1 Term. Subject to the terms and conditions set forth in this
Agreement and the restrictions, terms and conditions of the Utility Agreement,
NEES Com hereby leases to FiveCom the FiveCom Fibers for a term commencing on
the Completion Date and continuing for an initial term of 20 years ("Initial
Term") unless sooner terminated in accordance with the terms of this Agreement.
Subject to NEES Com's rights and obligations under the Utility Agreement,
FiveCom shall have the right to negotiate with NEES Com for an extension of this
Agreement for up to two consecutive five-year periods, on an "as-is" basis,
commencing at the expiration of the Initial Term. The Initial Term and any
subsequent extension are referred to in this Agreement as the "Term."

         7.2 Leasehold. The number, identity, and location of FiveCom Fibers
shall be set forth in a schedule that will be one of the Deliverables to be
provided under Section 6. FiveCom shall only have the right to use the fiber
optic filaments within the Cable designated as FiveCom Fibers on that
Deliverable, and the remaining fiber optic filaments within the Cable shall be
designated as NEP Fibers.

         7.3 Fiber Optic Facilities. FiveCom's lease of the FiveCom Fibers is
solely for FiveCom's use in providing fiber optic facilities to its customers.
FiveCom shall exercise such right solely to provide facilities to its customers
in accordance with this Agreement and applicable state, local, and federal laws
and regulations, consistent with FiveCom's obligations in Section 15.

         7.4 Nonexclusivity. Although FiveCom's right to use the FiveCom Fibers
shall be exclusive, FiveCom's use of other portions of the Cable, Cable
Accessories, Structures or any related facilities of NEES Com or its Affiliates
under this Agreement shall be nonexclusive and limited to the use necessary for
incidental support and/or placement of the FiveCom Fibers. Nothing in this
Agreement shall be construed as limiting or restricting NEES Com or its
Affiliates in any manner from using the Cables, Cable Accessories and the
Structures, or any other facilities, easements and/or rights of way for the
installation of additional fiber optic cables, for use as telecommunications
facilities, or for any other purpose. For purposes of this Agreement, the term
"Affiliate" shall mean: (a) any entity controlling, controlled by or under
common control with a Party, directly or indirectly, or (b) any entity which is
a successor to a Party or any of the foregoing entities by merger, consolidation
or otherwise.

         7.5 Right Subject to Utility Agreement. FiveCom acknowledges that NEES
Com's ability to lease to FiveCom the right to use the FiveCom Fibers pursuant
to this Section 7 shall at all times be subject to NEES Com's rights and
obligations under the Utility Agreement; provided, however, that this Agreement
shall be subject to subsequent amendments to the Utility Agreement if each of
the following conditions has been satisfied: (i) copies of such amendment have
been given to FiveCom, (ii)such amendments [**], (iii) [**], has provided
FiveCom [**] and (iv) [**] related to the amendment of the Utility Agreement. By
virtue of this Agreement, FiveCom shall have no greater rights with respect to
the location and use of the FiveCom Fibers than NEES Com has under the Utility
Agreement, and FiveCom's leasehold interest is expressly limited by any
applicable restrictions in the Utility Agreement. NEES Com shall not be liable
for any acts or omissions by NEES

FiveCom's use of the FiveCom Fibers to the extent such acts or omissions are
required by the Utility Agreement, including without limitation acts or
omissions that deny the use of, alter or remove the Cable, Cable Accessories and
Structures to preserve NEES Com's Affiliates' ability to provide safe and
reliable electric service. NEES Com agrees to use its best commercial efforts to
enforce and to exercise its rights under the Utility Agreement to facilitate the
performance of this Agreement.


8.       LEASE PAYMENTS.

         8.1 Base Fiber Payments. Commencing on the Completion Date pursuant to

                  pursuant to this Section 8.2 accurately reflect FiveCom's
                  [**]. Five Com shall reimburse NEES Com for its costs of such
                  audits, unless the audit reveals a discrepancy in the amount
                  [**] determined by FiveCom is less than [**], in which case
                  NEES Com shall pay for the audit. In addition, subject to a
                  mutually agreed confidentiality agreement, the respective
                  presidents of NEES Com and Beco Com shall be permitted to

                  1-800-891-5080. In the event of an emergency, FiveCom shall be
                  notified at this number as soon as the emergency is
                  discovered.

         9.3      Replacement Fiber.

         (a)      Initial Term [**]  In the event all or any part of the FiveCom
                  Fibers shall require replacement during [**] of the Initial
                  Term of this Agreement as a result of their failure to satisfy
                  the Specifications, such replacement shall be made as soon as
                  reasonably practical, [**]. If replacement of the FiveCom
                  Fibers is required in accordance with the preceding sentence,
                  NEES Com shall give FiveCom written notice of such replacement
                  as soon as reasonably practical before the replacement optical
                  fiber cable is ordered from the manufacturer. This obligation
                  to replace only applies to the number of FiveCom Fibers that
                  meet the Specifications on the Completion Date plus any
                  additional fiber optic strands leased to FiveCom pursuant to
                  Section 5.5.

         (b)      Initial Term [**]. [**] the Initial Term of this Agreement,
                  the costs of replacing the FiveCom Fibers shall be shared in
                  accordance with the following schedule:

                           Year             NEES Com's        FiveCom's

                                                   [**]

                  FiveCom shall have the option of not replacing the failed
                  fibers, or of terminating this Agreement prior to the end of
                  the Initial Term of this Agreement in lieu of sharing in the
                  cost of replacing the FiveCom Fibers; provided that FiveCom
                  may only exercise this right to terminate if, prior to any
                  replacement, [**]FiveCom Fibers meet the Specifications. If
                  FiveCom opts to replace the fibers, the portion of the
                  replacement fibers paid for by FiveCom's share of the costs of
                  such replacement shall be designated as "FiveCom Replacement
                  Fiber."

                  Cable with a new cable having an increased number of fiber
                  optical strands for FiveCom's use; provided that such
                  replacement shall be installed at FiveCom's incremental cost
                  (including provision for any related federal, state, or local
                  taxes on a grossed-up basis) and under terms mutually agreed

income taxes imposed on the receipt of payments made by FiveCom to NEES Com
under this Agreement.

         11.3     Tax Accounting; Reporting of Income Taxes.

         (a)      Except as provided in Section 11.3(b), FiveCom will not, for
                  any income tax purposes, account for FiveCom Fibers as the
                  owner thereof and is not entitled to and will not claim any
                  depreciation deductions and/or other tax attributes, credits
                  or benefits with respect to ownership of the FiveCom Fibers
                  for purposes of federal, state and local income taxes.

         (b)      Subject to the Utility Agreement, NEES Com or its Affiliate 
                  shall hold legal title to the FiveCom Replacement Fiber, but
                  FiveCom shall be the beneficial owner of FiveCom Replacement
                  Fiber for a period of time commencing on the date that the
                  FiveCom Replacement Fiber is installed and continuing until
                  the beneficial ownership reverts back to NEES Com pursuant to
                  Section 11.7 or Section 17.4(c). As beneficial owner of the
                  FiveCom Replacement Fiber, FiveCom shall for tax purposes
                  account for the FiveCom Replacement Fiber as owner thereof
                  and, as between the Parties shall be entitled to any
                  investment tax credits, depreciation and any other tax
                  attributes with respect to the FiveCom Replacement Fiber. NEES
                  Com agrees that it will not, for tax purposes, account for
                  such FiveCom


                                      -17-


<PAGE>



                  Replacement Fiber as though it were the owner thereof, and
                  shall not attempt to claim any of the tax attributes or
                  liabilities with respect thereto.


         (c)      The Parties agree they will file all income tax returns and
                  otherwise take all actions with respect to income taxes in a
                  manner consistent with the foregoing. Notwithstanding the
                  foregoing, in the event that a taxing authority with
                  appropriate jurisdiction determines that NEES Com is the
                  beneficial owner of the FiveCom Replacement Fiber for tax
                  purposes or that the FiveCom Replacement Fiber should be
                  accounted for in a manner other than the tax accounting
                  specified in Section 11.3(b), FiveCom agrees to indemnify NEES
                  Com fully against any and all federal, state and/or local
                  income tax, interest, and penalty claims incurred as a result
                  of such taxing authority's determination.


         11.4     Sales Taxes.

         (a)      NEES Com will be responsible for paying any and all existing
                  or future sales, excise or other transfer or transactional
                  taxes imposed or levied by any federal, state or local taxing
                  authority on purchases of materials and/or equipment for use
                  in construction of the Cable. NEES Com anticipates purchasing
                  all materials and equipment for use in acquiring and
                  installing the Cable exempt from sales and use tax as a resale
                  transaction. FiveCom agrees that, if it purchases any
                  materials for use in the acquisition or installation of the
                  Cable as NEES Com's agent, it will provide the vendors with
                  NEES Com's resale exemption certificate. If FiveCom fails to
                  provide the vendors with the exemption certificate, NEES Com
                  will be under no obligation to reimburse FiveCom for any sales
                  tax paid to the vendors or any taxing authority related to
                  such purchases.

         (b)      FiveCom will be responsible for paying any and all existing or
                  future sales, excise or other transfer or transactional taxes
                  imposed or levied by any federal, state or local taxing
                  authority on the lease payments provided for in Section 8
                  and/or other payments made by FiveCom to NEES Com for the use
                  by FiveCom of FiveCom Fibers. NEES Com agrees to cooperate at
                  FiveCom's expense in any proper claim of exemption or
                  exclusion from such taxes which FiveCom may assert. FiveCom's
                  obligation to pay for the taxes provided for in this Section
                  11.4(b), shall be suspended to the extent that FiveCom can
                  provide to NEES Com a valid ruling from the appropriate taxing
                  authority that provides that such taxes are not due;


                                      -18-


<PAGE>



                  provided that FiveCom's obligation shall only be suspended for
                  the period of time that the tax ruling remains valid and that
                  FiveCom shall indemnify NEES Com fully against any and all
                  such taxes, interest, and penalty claims incurred as a result
                  of the modification, termination or overruling of such tax
                  ruling or a finding that the tax ruling was not valid.

         11.5 Franchise, Property and Other Taxes or Fees. Upon notice from NEES
Com to FiveCom, FiveCom shall promptly reimburse NEES Com for any increase in or
addition to any existing federal, state or local excise, franchise, ad valorem,
property or similar taxes, payments or payments in kind, or any similar fees
such as franchise fees, license fees or user fees imposed on NEES Com or billed
to NEES Com under Section 27 of the Utility Agreement, which increase or
addition, is attributable to the presence of FiveCom Fibers on Structures, Cable
Accessories, and equipment. NEES Com agrees to cooperate with FiveCom to the
extent that FiveCom seeks to contest, by appropriate legal process, the
assessment by the relevant governmental authority of any tax, fee or other
charge for which FiveCom becomes liable hereunder; provided that such obligation
to cooperate does not include the obligation of NEES Com (1) to participate in
any tax contest on FiveCom's behalf; (2) to ensure that FiveCom has the right to
initiate or to participate in such tax contest; or (3) to ensure that its
Affiliates do not take positions in such tax contests that are inconsistent with
FiveCom's position.

         11.6 Levy. FiveCom and NEES Com shall properly remit all tax payments
in a timely manner to the applicable taxing authorities or governmental agencies
and will not cause the Cable to be levied, attached, or otherwise encumbered by
any taxing authority or governmental agency through any failure to remit such
payments.

         11.7     Reversion.

         (a)      FiveCom's right to use the FiveCom Fibers and FiveCom's
                  beneficial ownership of the FiveCom Replacement Fibers shall
                  revert to NEES Com, at no additional cost to NEES Com, upon
                  termination of this Agreement.

         (b)      FiveCom's right to use any fibers within any portion of the
                  Route shall revert to NEES Com, at no additional cost to NEES
                  Com, upon the termination of that portion of the Route
                  pursuant to Section 17.2.

         (c)      FiveCom agrees to pay for any federal, state, or local taxes
                  and the Tax Impact of such taxes incurred by or billed to NEES
                  Com as a result of the reversion of the FiveCom Replacement
                  Fiber. For purposes of this Agreement, "Tax Impact" shall mean
                  an amount equal to the excess of (i) the sum of the federal,
                  state and local income taxes incurred by NEES Com

                  or any Affiliate on reimbursements from FiveCom of federal,
                  state and local income taxes over (ii) the sum of (x) the
                  present value of the Tax Benefit to NEES Com or any Affiliate
                  resulting from the transaction to which the reimbursement
                  relates, and (y) in the case of replaced property, an amount
                  equal to the excess of the present value of depreciation
                  deductions computed using revised (accelerated) useful life of
                  replaced property over the present value of such depreciation
                  deductions computed using the original useful life of the
                  property. "Tax Benefit" shall mean the amount of any
                  reductions in taxes resulting from any item including, without
                  limitation, all tax credits, depreciation deductions and other
                  expense deductions in connection with the purchase or
                  ownership of the Cable or any other transaction to which the
                  reimbursement relates. The present valuations described above
                  shall be determined by applying a discount rate of [**] per
                  annum.


12.      LIMITATION ON LIABILITY.

         12.1 Exclusion of Certain Types of Damages. Neither FiveCom nor NEES
Com shall be liable to the other for any indirect, special, punitive, or
consequential damages, or any lost business damages in the nature of lost
revenues or profits (including, but not limited to any claim from any customer
related to loss of service, except to the extent specifically contemplated in
Section 8.2 as a deduction from gross revenue) arising under this Agreement, or
arising out of any act or omission of either Party hereto, its respective
employees, agents, or contractors. NOTHING IN THIS AGREEMENT SHALL MAKE EITHER
PARTY LIABLE TO THE CUSTOMERS OR CONTRACTORS OF THE OTHER PARTY FOR ANY DAMAGES,
WHETHER IN CONTRACT, TORT, OR OTHERWISE FOR ANY OF THE PARTIES' ACTS OR
OMISSIONS ASSOCIATED WITH THIS AGREEMENT.

         12.2 Limitation on NEES Com Damages. Notwithstanding any other
provision of this Agreement, the total amount of monetary damages to which NEES
Com shall be subject by reason of this Agreement shall [**] (a) [**] or (b) [**]
hereunder. Nothing herein shall be deemed a limitation on FiveCom's right to
seek specific performance or injunctive relief for the breach of any obligation
of NEES Com hereunder.

         12.3 Limitation on FiveCom Damages. Notwithstanding any other provision
of this Agreement, the total amount of monetary damages to which FiveCom shall
be subject by reason of this Agreement shall [**] (a) [**] or (b) [**]
hereunder. Nothing herein shall be deemed a limitation on NEES Com's right to
seek specific performance or injunctive relief for the breach of any obligation
of FiveCom hereunder.

         12.4 No Limitation on Third-Party Actions. Nothing contained in this
Agreement shall operate as a limitation on the right of either Party hereto to
bring an action for damages, including consequential damages, against any Third
Party based on any acts or omissions of such Third Party as such acts or
omissions may affect the construction, operation or use of the FiveCom Fibers.
With the exception of claims against NEES Com's utility Affiliates, each Party
hereto shall assign such rights or claims, execute such documents, and at the
request of and at the sole cost of the other Party, take such other action as
may be reasonably necessary to enable the injured Party to pursue any such
action against such Third Party.

13.      INDEMNIFICATION.

         13.1 By NEES Com. NEES Com shall indemnify, defend and save FiveCom,
its officers, directors and employees ("FiveCom Indemnified Parties"), harmless
from and against any and all actions, charges, claims, damages, expenses, fines,
penalties and liabilities whatsoever actually incurred by FiveCom Indemnified
Parties arising from, or out of, or in connection with any of the following:

                  respective Affiliates, employees, agents, or any other person
                  acting by or through, or with the knowledge and approval of
                  FiveCom or BecoCom; and

         (c)      Any storage, use, spill, discharge or release to the 
                  environment of any oil or hazardous materials or wastes, as
                  those terms are defined by applicable federal or state law
                  from time to time, in or upon any property adjacent to the
                  FiveCom Fibers or the Structures by NEES Com, its Affiliates,
                  or their respective employees, agents, contractors, or any

                  other person acting by or through, or with the knowledge and

Com, its Affiliates, officers, directors and employees ("NEES Com Indemnified

                  its Affiliates, employees, agents, contractors or any other
                  person acting by or through, or with the knowledge and
                  approval of NEES Com;

         (b)      The violation of federal, state or local law, regulation or
                  ordinance applicable to the Cable, Cable Accessories,
                  Structures, FiveCom Fibers, and FiveCom's use thereof, by

<PAGE>



                  or with the knowledge and approval of FiveCom, except to the
                  extent caused by the negligence or willful misconduct of NEES
                  Com, its Affiliates, employees, agents, contractors or any

         13.3 Indemnity Obligation. The indemnity obligation includes reasonable
attorneys' fees, investigation costs, and all other reasonable costs and
expenses incurred by the FiveCom Indemnified Party or NEES Com Indemnified
Party, as the case may be, from the first notice that any claim or demand has
been made or may be made, and is not limited in any way by any limitation on the
amount or type of damages, compensation, or benefits payable under applicable
workers' compensation acts, disability benefit acts, or other employee benefit
acts.

14.      FORCE MAJEURE.

         14.1 Force Majeure Events. Neither FiveCom nor NEES Com shall be liable
for any failure or delay in performing its obligations hereunder, or for any
loss or damage resulting therefrom, due to the following Force Majeure Events:

         (a)      Fire, flood, strike or other labor difficulty, natural 
                  disasters (including, without limitation, tornadoes,
                  hurricanes, ice storms, and other significant weather
                  phenomena), equipment failure, war, embargo, riot or
                  insurrection, acts of God or public enemy, restraint or
                  hindrance by any governmental or regulatory authority
                  (including, without limitation, denial of necessary permits or
                  licenses, imposition of commercially unreasonable conditions,
                  delays or other failures to act of or by such authorities,
                  except when the result of a failure to use best commercial
                  efforts by the Party claiming force majeure); or

         (b)      any other causes beyond the Parties' reasonable control.


                                      -23-


<PAGE>



         14.2 Abatement of Force Majeure. To the extent practicable, both
Parties shall be prompt in restoring normal conditions, establishing new
schedules and resuming operations as soon as the Force Majeure Event causing the
failure or delay has ceased. FiveCom shall promptly notify NEES Com of any delay
constituting a Force Majeure Event, and its effect on the performance by
FiveCom. NEES Com shall promptly notify FiveCom of any delay constituting a
Force Majeure Event, and its effect on the performance by NEES Com.

         14.3 Suspension Pending Force Majeure. If a Force Majeure Event should
occur, then the Parties' performance of this Agreement, except for payments by
FiveCom to NEES Com under Section 8.1, shall be suspended for so long as such
Force Majeure Event continues. At the conclusion of a Force Majeure Event, the
period of time during which performance was so suspended shall be added to the
dates, schedules and other performance-related matters under this Agreement. If,
notwithstanding the Parties' efforts under Section 14.2, the Force Majeure Event
continues unabated for more than 6 months, the Party whose performance is
unaffected by the Force Majeure Event shall have the option to terminate this
Agreement.


         14.4     Labor Disputes.

         (a)      If an actual or potential labor dispute delays or threatens 
                  to delay a Party's performance, that Party shall immediately
                  notify the other Party in writing, stating all relevant
                  information concerning the dispute and its background. The
                  Parties shall include this paragraph in any subcontract for
                  services (with a contractor other than an Affiliate) if a
                  labor dispute thereunder might delay the timely performance of
                  the services, and each such subcontract shall provide that if
                  any actual or potential labor dispute occurs, the lower-tier
                  subcontractor shall immediately notify the Parties of all
                  relevant information concerning such dispute.

         (b)      If NEES Com reasonably determines that FiveCom's activities 
                  pursuant to this Agreement in or near the Route are causing or
                  will cause labor difficulties for NEES Com or its Affiliates,
                  FiveCom shall discontinue those activities until the labor
                  difficulties have been resolved; provided, however, that in
                  any such event and notwithstanding any other provision of this
                  Agreement, NEES Com shall during the period of such labor
                  difficulties perform, or cause to have performed, at FiveCom's
                  expense (utilizing the lowest market rate reasonably
                  available) any such activities to the extent reasonably

                  under this Agreement with respect to such portion of the Route
                  or it is prohibited by a governmental authority from
                  performing such obligations with respect to such portion of
                  the Route, provided that NEES Com, to the extent reasonably
                  practicable, has provided FiveCom prompt notice of any

18.      CONDEMNATION.

         18.1 Condemnation of FiveCom Fibers. In the event any portion of the
FiveCom Fibers, or the rights-of-way in or upon which they shall have been
installed, become the subject of a condemnation proceeding by any governmental
agency or other party cloaked with the power of eminent domain for public
purpose or use, and such action precludes the continued use of the FiveCom
Fibers by FiveCom, as contemplated by this Agreement, then and in such event, it
is agreed that NEES Com shall use best commercial efforts to [**]. To the extent
allowed by law and subject to the restrictions, terms and conditions in the
Utility Agreement, FiveCom shall be [**].

         18.2 Condemnation of Other Portions of the FiveCom Network. In the
event any portion of the FiveCom Network other than the FiveCom Fibers, or the
rights-of-way in or upon which the FiveCom Network shall have been installed,
become the subject of a condemnation proceeding by any governmental agency or
other party cloaked with the power of eminent domain for public purpose or use,
then and in such event, it is agreed that FiveCom shall use best commercial
efforts to obtain an alternative route over which the FiveCom Network may be
relocated, at no cost to NEES Com to ensure that FiveCom can maintain its then
existing customers and level of gross revenues. To the extent that FiveCom
Fibers can still be used to serve FiveCom's customers, FiveCom shall continue to
lease the FiveCom Fibers and shall continue to be obligated under terms of this
Agreement, including without limitation its obligations to pay the lease
payments provided for under Section 8; provided, however, that if, after the
first year in the Term of this Agreement, FiveCom's gross revenues derived from
the FiveCom Network in a [**] and subject to sharing under Section 8.2 decrease
as a result of the condemnation, by [**] below the level of gross revenues in
the [**], NEES Com shall have the option to provide FiveCom notice that FiveCom
will have [**] to secure alternate capacity or facilities to restore its gross
revenues or the Agreement will be terminated.

notify the other Party of any similar threatened condemnation proceeding and
agrees not to sell any property associated with or affecting the FiveCom Fibers
or FiveCom Network to such acquiring agency, authority or other party in lieu of
condemnation without prior written notice to the other Party.

19.      RELATED AGREEMENTS.

         19.1 BecoCom/FiveCom Agreement. Simultaneously with the execution of
this Agreement, FiveCom is entering into a similar agreement with BecoCom (the
"BecoCom/FiveCom Agreement") pursuant to which FiveCom is leasing fiber optic
facilities from the NEES Com-BecoCom Demarcation Point to various points in
Boston, Massachusetts. The Parties hereby agree that FiveCom's obligations under
this Agreement are not conditioned upon the execution of, compliance with, or
continued enforceability of the BecoCom/FiveCom Agreement; provided, however,
that the Parties agree to make appropriate changes to the revenue sharing in
Section 8.2 of this Agreement in the event that the BecoCom/FiveCom Agreement is
not executed, is terminated, or ceases to be enforceable.

         19.2 Initial Unavailability. If BecoCom shall fail to complete the
installation of fiber optic cable (either on a timely basis or at all) as
required by the BecoCom/FiveCom Agreement, FiveCom's obligation to make payments
under Section 8 of this Agreement shall nevertheless commence on the Completion
Date; provided, however, that if the Completion Date has occurred and the fiber
optic cable under the BecoCom/FiveCom Agreement remains uncompleted for a period
of [**] after the Completion Date hereunder, NEES Com shall have the option to
provide FiveCom notice that FiveCom will have [**] to secure alternate capacity
or facilities [**] or the Agreement will be terminated.

         19.3 Subsequent Unavailability. If following the Completion Date any
portion of the FiveCom Network other than the FiveCom Fibers shall become
unavailable to FiveCom, FiveCom shall continue to be obligated under this
Agreement. In particular, to the extent that FiveCom Fibers can still be used to
serve FiveCom's customers, FiveCom shall continue to lease the FiveCom Fibers
and to be obligated to pay the lease payment provided under Section 8; provided,
however, that if, after the first year in the

Term of this Agreement, [**] derived from the FiveCom Network in a [**] other
portion of the FiveCom Network by [**] in the prior [**], NEES Com shall have
the option to provide FiveCom notice that it will have [**] to secure alternate
capacity or facilities [**] or the Agreement will be terminated.

                  limited to, disclosure to the Securities and Exchange
                  Commission.

         20.2     Obligations Concerning Proprietary Information.

         (a)      General Restrictions.  Upon receiving Proprietary Information,
                  the Party receiving the Proprietary Information ("Receiving
                  Party") shall keep in strict confidence and not disclose to
                  any person (with the exception of employees, officers,
                  directors, agents or representatives, and Affiliates of the
                  Receiving Party, to the extent each such person or entity has
                  a need to know in connection herewith) any of the Disclosing
                  Party's Proprietary Information except as otherwise provided
                  by the terms and conditions of this Agreement. The Receiving
                  Party shall not use such Proprietary Information except for
                  the purposes identified herein without the prior written
                  approval of the Disclosing Party. The Receiving Party shall be
                  solely liable for any breach of this Section 20.2 to the
                  extent caused by its or its Affiliates' employees, officers,
                  directors, agents or representatives.

         (b)      Additional Marking Requirements. In the event either Party
                  discloses its Proprietary Information to the other Party
                  unmarked or in oral or visual form, the Disclosing Party shall
                  notify the Receiving Party in writing that such Information is
                  deemed proprietary within 48 hours of its disclosure. Such
                  Proprietary Information shall be treated in the manner set
                  forth above from the date such written notice is received.

         (c)      Exceptions. The Receiving Party shall not be precluded from,
                  nor liable for, disclosure or use of any Proprietary
                  Information if:

                           (i)      the Proprietary Information is in or enters 
                                    the public domain, other than by a breach of
                                    this Agreement;

                           (ii)     the Proprietary Information is known to the
                                    Receiving Party at the time of first
                                    receipt, or thereafter becomes known to the
                                    Receiving Party prior to or subsequent to
                                    such disclosure without similar restrictions
                                    from a source other than the Disclosing
                                    Party, as evidenced by written records;

                           (iii)    the Proprietary Information is developed by
                                    the Receiving Party independently of any
                                    disclosure under this Agreement as evidenced
                                    by written records;

                           (iv)     the Proprietary Information is disclosed
                                    more than 5 years after the date of first
                                    receipt of the disclosed Proprietary
                                    Information; or 5 years after the Term
                                    whichever occurs later;

                           (v)      disclosure of the Proprietary Information is
                                    compelled by a government authority,
                                    including, but not limited to any court or
                                    regulatory body, provided that the Receiving
                                    Party has used its best efforts to resist
                                    disclosure of, redact, or otherwise protect
                                    the confidentiality of the economic terms of
                                    this Agreement, including without limitation
                                    Section 8.

                           (vi)     the Disclosing Party consents to the 
                                    disclosure or use of the Proprietary 
                                    Information; or

                           (vii)    the Receiving Party has a reasonable belief
                                    that disclosure of the Proprietary
                                    Information is necessary for public safety
                                    reasons and has attempted to provide as much
                                    advance notice of the disclosure as is
                                    practicable.

                           (viii)   disclosure entails only recordation of this
                                    Agreement by FiveCom with appropriate
                                    registries of deeds or other public records;
                                    provided that NEES Com has received 30 days
                                    prior notice of such recordation and that
                                    FiveCom records only a notice of lease in
                                    the form provided in Exhibit 20.2 or other
                                    similar short-form record to which NEES Com
                                    has agreed prior to such recordation.

         (d)      Disclosures. The disclosure of Proprietary Information
                  hereunder shall not be construed as granting any right of
                  ownership in said Proprietary Information.

21.      DEFAULT.

         21.1 By FiveCom. A breach by FiveCom of any of its representations,
covenants or obligations under this Agreement which is not cured as provided
herein shall constitute a "Default" by FiveCom. FiveCom shall not be in Default
under this Agreement, or in breach of any provision hereof unless and until NEES
Com shall have given FiveCom written notice of such breach and FiveCom shall
have failed to cure the same within [**] after receipt of such notice; provided,
however, that the foregoing notice and cure requirement shall not apply to
FiveCom's obligation to make payments in a timely manner as provided under
Sections 8.2(e) and 8.4 hereof or where Section 17.1 provides for an alternate
notice and cure requirement. Where any such breach, other than a breach of
Sections 8.2(e) and 8.4, cannot reasonably be cured within such [**] period, if
FiveCom shall proceed promptly to cure the same and prosecute such curing with
due diligence, the time for curing such breach shall be extended for such period
of time as may be necessary to complete such curing. Upon the failure by FiveCom
to timely cure any such breach after notice thereof from NEES Com, NEES Com
shall have the right, in its sole discretion, to take such action, consistent
with Section 17.1, as it may determine, to be necessary to cure the breach or to
terminate this Agreement upon written notice to FiveCom.

         21.2 By NEES Com. A breach by NEES Com of any of its representations,
covenants or obligations under this Agreement which is not cured as provided
herein shall constitute a "Default" by NEES Com. NEES Com shall not be in
default under this Agreement or in breach of any provision hereof unless and
until FiveCom shall have given NEES Com's written notice of such breach and NEES
Com shall have failed to cure the same within [**] after receipt of such notice;
provided, however, that the foregoing notice and cure requirement shall not
apply where Section 17.1 provides for an alternate notice and cure requirement.
Where any such breach cannot reasonably be cured within such [**] period, if
NEES Com shall proceed promptly to cure the same and prosecute such curing with
due diligence, the time for curing such breach shall be extended for such period
of time as may be necessary to complete such curing. Upon the failure by NEES
Com to timely cure any such breach after notice thereof from FiveCom, FiveCom
shall have the right, in its sole discretion, to take such action, consistent
with Section 17.1, as it may determine to be necessary to cure the breach or to
terminate this Agreement upon written notice to NEES Com; provided that the
foregoing right to self-help shall not be construed to allow FiveCom or its
agents or contractors physical access to the Cable, Cable Accessories, or
Structures.

23.      DISPUTE RESOLUTION.

         23.1 In the event of any dispute between the Parties hereto as to a
matter referred to herein or as to the interpretation of any part of this
Agreement, including but not limited to this Section 23 or as to the
determination of any rights or obligations or entitlements arising from or
related to this Agreement or as to the calculation of any amounts payable under
this Agreement, the Parties shall refer the matter to their respective chief
executive officers for resolution.

         23.2 Should the chief executive officers of the respective Parties fail
to resolve the dispute within 30 days from such referral, the Parties agree that
such dispute will not be referred to any court but will be referred to binding
arbitration, and the provisions of this Section 23 shall apply.

         23.3 The arbitration shall be governed by the AAA Commercial
Arbitration Rules (the "Rules") as modified by this Section 16 and by the United
States Arbitration Act, 9 U.S.C. ss.ss. 1 et seq. (The "Arbitration Act"). Any
conflict between the Rules and the Arbitration Act shall be decided in favor of
the Rules. The Party wishing to submit such matter to arbitration shall give
written notice (the "Arbitration Notice") to the other Party (the "Respondent")
of its intention to arbitrate. The place of the arbitration shall be


                                      -36-


<PAGE>



Boston, Massachusetts. The arbitration shall be conducted, and the final
resolution of the dispute (the "Award") shall be rendered by a panel to be
selected by mutual agreement of the Parties ("Arbitration Panel"), which shall
consist of one arbitrator or, if the dispute involves damages in excess of
$50,000, three arbitrators. If the Parties cannot agree to a mutually acceptable
Arbitration Panel within seven days of Respondent's receipt of the Arbitration
Notice, the Arbitration Panel shall be selected in accordance with rule 13 of
the Rules.

         23.4 The Arbitration Notice shall be served on BecoCom. If either Party
reasonably requests or if BecoCom so chooses, BecoCom shall participate in any
arbitration proceedings brought hereunder. NEES Com hereby agrees to submit to
any arbitration arising under the BecoCom/FiveCom Agreement upon reasonable
request of either FiveCom or BecoCom.

         23.5 Prior to the first day of the hearing, each Party shall be
entitled to reasonable document discovery and three depositions of the other
Party's witnesses or employees; provided that the Parties will may conduct
additional discovery upon a finding by the Arbitration Panel that there is good
cause for such additional discovery.

         23.6 All hearings shall be held within 120 days following the
appointment of the Arbitrator, or within an earlier time frame mutually agreed
to by the Parties. At a time designated by the Arbitration Panel, each Party
shall simultaneously submit to the Arbitration Panel and exchange with each
other its proposed Award, and in rendering the final Award, the Arbitration
Panel shall be limited to choosing the Award proposed by either of the Parties
without modification; provided that any final Award shall provide an equitable
allocation of the fees and expenses of the arbitration, including without
limitation the arbitration expenses of each Party and of BecoCom; provided
further that the Arbitrator shall not have any authority to make any Award that
provides for punitive, any indirect, special, punitive, or consequential
damages, or any lost business damages in the nature of lost revenues or profits.
The Arbitration Panel shall issue the final Award no later than 15 days from the
completion of the hearings. The Award shall be final and binding. Judgment on
any Award may be entered in any court having jurisdiction thereof.

         23.7 Either Party may seek preliminary injunctive relief from a court
of competent jurisdiction, which relief, if granted, shall remain effective
pending resolution of the arbitration, and each Party consents and submits to
the non-exclusive jurisdiction of and venue in the federal courts located in
Boston, Massachusetts (or, in case such a federal court does not have
jurisdiction, the state courts located in Boston, Massachusetts). Each Party
consents to service of the notice of arbitration, and any other paper in the
arbitration, by registered mail or personal delivery at its address specified in
Section 22 hereof. Nothing in this Section 23.7 shall limit the jurisdiction of
other courts for purposes of enforcement of a final arbitration Award.

         23.8 The fact that any Party has invoked the provisions of this Section
23 shall be considered to be Proprietary Information under Section 20.1 of this
Agreement and shall not relieve either Party of any obligations it may otherwise
have to continue performance in accordance with the provisions of this
Agreement.

         23.9 This Agreement to arbitrate a dispute in accordance with this
Section 23 and any Award made hereunder shall be binding upon the successors and
assigns and any trustee or receiver of each of the Parties hereto.

24.      LIENS.

         24.1 Future Liens. In addition to their obligations under Section 15,
the Parties hereby agree that if the Cable, Cable Accessories, Structures, or
FiveCom Fibers are or become subject to any mechanics', artisan's or
materialmen's lien, or other encumbrance chargeable to or through a Party, that
Party shall promptly cause such lien or encumbrance to be discharged and
released of record (by payment, posting of bond, court deposit or other means)
without cost to the other Party and shall indemnify that other Party against all
costs and expenses (including reasonable attorney's fees) incurred in
discharging and releasing such lien or encumbrance; provided, however, that if
any such lien or encumbrance is not so discharged and released within 30 days
after written notice to the Party responsible for the lien, then the other Party
may pay for or secure the release or discharge thereof at the expense of Party
responsible for the lien.

         24.2 Existing Liens. To the extent that [**], NEES Com shall use best
commercial efforts to [**].

25. INSURANCE. Prior to execution of this contract, each Party, at its own
expense, shall provide and maintain in force during the term of this Agreement
insurance in forms acceptable to the other Party, with the following minimum
levels of coverage:

                  Commercial general
                  liability and automobile
                  liability                     [**] per person per occurrence

                  Damage to Property
                  of Third Parties              [**] per occurrence


                  Umbrella/Excess Coverage      [**]

                  Employer's liability:         [**] per occurrence;


                                      -38-


<PAGE>



                  Workers compensation: statutory limits, in accordance with the
                                        laws of the states wherein operations
                                        under this Agreement will take place.

Each Party shall be solely responsible for procuring, and paying for, its
respective insurance coverage. Any such policy(ies) shall be procured from an
insurance company with a "Best" rating of A or better, and qualified to do
business in the relevant jurisdiction. Certificates evidencing such policy(ies)
shall be delivered by the Party obtaining the insurance to the other Party
within 30 days of the date of this Agreement. Not less than 30 days prior to the
expiration date of such policies, certificates evidencing the renewal thereof
shall be delivered by the Party obtaining the insurance to the other Party. Such
policies shall further provide that not less than 30 days' written notice shall
be given by the Party obtaining the insurance to the other Party before such
policy(ies) may be canceled, materially changed or undergo a reduction in
Insurance limits provided thereby. The Party obtaining the insurance shall
designate the other Party as an additional insured. The coverage required herein
shall not be deemed to limit either Party's liability under this Agreement. Upon
timely notice to the Party obtaining the insurance, the other Party may request
reasonable increases in the amount of insurance coverage which will be obtained
within 30 days, at the cost of the requesting Party.

26.      ASSIGNMENT.

         26.1 No Assignment. Neither Party shall assign, transfer, delegate,
sublease, or in any other manner dispose of, any of its rights, privileges or
obligations under this Agreement without the non-assigning Party's prior written
consent, which shall not be unreasonably withheld. Any attempt to make any such
assignment, transfer or disposition without such prior written consent of the
non-assigning Party shall be null and void. Notwithstanding the foregoing,
FiveCom may sublease or otherwise transfer its rights under this Agreement
without NEES Com's consent if, notwithstanding its best commercial efforts,
FiveCom has been unable to construct and install the non-optronic portion of the
FiveCom Portion as required by Section 4.5 and to the extent necessary to
effectuate its business of providing telecommunications facilities to its
customers, and either Party may assign this Agreement without consent either (i)
to an Affiliate or (ii) in connection with a transaction pursuant to which the
Party sells all or substantially all of its business, assets or equity
interests.

         26.2 Right to Pledge Agreement and Transfer Property. Either Party
shall be free to mortgage, pledge, or otherwise assign its interests under this
Agreement to any Non-Party in connection with any borrowing or other financing
activity of that Party provided that such assignment shall not limit or
otherwise affect that Party's obligations under this Agreement. Any transfer of
property of either Party included in or subject to this Agreement may be made by
that Party provided the person acquiring such property takes it subject to this
Agreement. Nothing in this Section 26 shall limit or apply to NEP's right to
lease or sublease the NEP Fibers to Non-Parties.

         26.3 Agreement Binding; Assignees.  This Agreement shall be binding 
upon and inure to the benefit of the Parties and their respective successors and
assigns where


                                      -39-


<PAGE>



permitted by this Agreement. In the event of a permitted assignment of this
Agreement, both Parties shall remain bound by their respective obligations under
this Agreement, unless an express release is given by the non-assigning Party.

made solely for the benefits of the Parties, and their respective successors and
permitted assigns. Nothing in this Agreement is intended to confer any
rights/remedies under or by reason of this Agreement on any Third Party. For
purposes of this Agreement, a "Non-Party" shall be any party, person or entity
that is not a signatory to this Agreement, and a "Third Party" shall mean any
Non-Party that is also not an Affiliate of a signatory nor a successor or
permitted assignee of the signatories hereto.

         27.3 Amendments; Waivers. This Agreement may be amended only by a
written instrument executed by the Party against whom enforcement of the
modification is sought. No failure to exercise and no delay in exercising, on
the part of either Party of any right, power or privilege under this Agreement
shall operate as a waiver of that right, power or privilege, except as expressly
provided in such waiver.

         27.4 Entire Agreement. This Agreement, and the Exhibits attached to it
constitute the entire agreement between the Parties with respect to the subject
matter of this Agreement and supersede any and all prior negotiations,
understandings and agreements with respect to this Agreement, oral or written.

         27.5 No Joint Venture. In all matters pertaining to this Agreement, the
relationship of NEES Com and FiveCom shall be that of lessor and lessee, and
neither NEES Com nor FiveCom shall make any representations or warranties that
their relationship is other than that of lessor and lessee. This Agreement is
not intended to create nor shall it be construed to create any partnership,
joint venture, employment or agency relationship between FiveCom and NEES Com,
and no Party shall be liable for the payment or performance of any debts,
obligations, or liabilities of the other Party, unless expressly assumed in
writing herein or otherwise. Each Party retains full control over the
employment, direction, compensation and discharge of its employees, and will be
solely responsible for all compensation of such employees, including social
security, withholding and worker's compensation responsibilities.

Sections 12.1 and 20 shall continue to apply; (ii) payments with respect to the
Term of the Agreement shall be made even though the due date for payment shall
be subsequent to the termination of the Agreement; and (iii) subject to the
applicable statutes of limitation, indemnification rights and claims arising
under the Agreement prior to termination shall survive such termination.

         27.8 Publicity. Neither Party shall make any public announcement using
the other Party's name or mentioning this Agreement without the written consent
of the other Party. For purposes of this Section 27.8, filings required by
government agencies shall not be considered to be public announcements.

                            FIBER OPTIC USE AGREEMENT


1. PREAMBLE. Effective July 2, 1998, BecoCom, Inc. ("BecoCom") and FiveCom, Inc.
("FiveCom") (collectively "Parties", singularly, "Party") agree as follows:

2. BACKGROUND. FiveCom has or is developing a fiber optic system from [**]
("FiveCom System"). To the FiveCom System, FiveCom wishes to add a fiber optic
network ("FiveCom Network") from [**] to a FiveCom Point of Presence ("POP") to
be built at [**]. The [**]. FiveCom, BecoCom, and NEES Communications, Inc.
("NEESCom") wish to jointly build their respective portions of this network
under the terms of separate agreements between FiveCom and BecoCom and between
FiveCom and NEESCom. The purpose of the FiveCom Network is to provide
telecommunications capacity between [**].

The FiveCom Network is described as follows: [**], is to be installed from the
[**], an underground fiber optic cable, consisting of [**], is to be installed.
From the [**] an underground fiber optic cable, consisting of [**], is to be
installed connecting the [**] POPs described above, and returning to the [**].
Exhibit 2 depicts the FiveCom Network.

FiveCom, BecoCom, and NEESCom are each responsible for constructing a portion of
this Network. These portions are defined by the following demarcation points:

         FiveCom - NEES Com Demarcation Point: This is defined as the splice box
         to be located on the [**].

         NEES Com - BecoCom Demarcation Point: This is defined as a mid-span
         point located above the town line between [**]. This demarcation
         occurs between Transmission Line [**]






                                      -1-

          Confidential Materials omitted and filed separately with the
        Securities and Exchange Commission. Asterisks denote omissions.


         [**]. Because this demarcation point is mid-span, joint or closely
         coordinated construction of the NEES Com and BecoCom [**] facilities
         must occur.

         FiveCom - BecoCom Demarcation Points: the "FiveCom - BecoCom
         Demarcation Point `A'" is defined as a mutually acceptable location
         along the Cambridge - Somerville city line, depending upon the exact
         route taken for the fiber optic cable installed between the FiveCom POP
         and Bent Street. The "FiveCom - BecoCom Demarcation Point `B'" is
         defined as a mutually acceptable location along the Cambridge - Boston
         city line, depending upon the exact route taken for the fiber optic
         cable installed between the [**].

         There will be additional demarcation points at the FiveCom POP and at
         each of the four carrier locations specified above. At each location,
         the Demarcation Point is defined as a splice box or patch panel
         installed in a mutually acceptable manner. If approval of the building
         owner is required, FiveCom shall be responsible for securing any
         necessary co-location rights.

         Having established the demarcation points, each portion of the Network
         can be described as follows:

         NEES Com Portion: A [**] fiber optic cable between the FiveCom - NEES
         Com Demarcation Point and the NEES Com - BecoCom Demarcation Point.

         BecoCom Portion: (a) A [**] fiber optic cable between the NEES Com -
         BecoCom Demarcation Point and the Demarcation Point at the FiveCom POP,
         plus (b) a [**] fiber optic cable from the Demarcation Point at the
         FiveCom POP to the FiveCom - BecoCom Demarcation Point "A", plus (c) a
         [**] fiber optic cable from the Demarcation Point at the FiveCom POP to
         the Demarcation Point at [**] to the Demarcation Point at [**] to the
         Demarcation Point at [**] to FiveCom - BecoCom Demarcation Point "B".

         FiveCom Portion: The initial electronics component of the FiveCom
         Portion is intended to be sufficient to operate (a) [**] between [**],
         and (b) [**] connecting the [**] carrier locations described above.
         FiveCom shall use its best commercial efforts install this electronic
         equipment within [**] after the Completion Date, and shall have some
         discretion to modify this electronic equipment to adjust to business
         conditions, but shall not eliminate or forgo a substantial portion of
         its capital investment responsibilities to install

         electronic equipment without the approval of BecoCom. FiveCom may
         install additional electronic equipment at its option. The non-optronic
         component of the FiveCom Portion shall consist of (a) a [**] fiber
         optic [**] cable from the [**] to the FiveCom - NEES Com Demarcation
         Point, plus (b) a [**] fiber optic cable from the FiveCom - BecoCom
         Demarcation Point A" to [**] to the FiveCom - BecoCom Demarcation Point

activities as part of its business to secure customers for the FiveCom Fibers,
and shall use its best commercial efforts throughout the Term to maximize the
revenues generated by the FiveCom Fibers.

5.       SCHEDULE.

         5.1 Completion Date. BecoCom shall use best commercial efforts to
complete construction and installation and to ensure that the Completion Date of
the FiveCom Fibers occurs on or before [**]. Unless otherwise determined under
Sections 5.3 or 5.4 below, the Completion Date shall be [**].

         5.2 Penalty for Late Delivery. For each day after [**] until the
Completion Date or the date this Agreement is terminated, BecoCom will pay to
FiveCom an amount equal to the sum of (a) [**] between the FiveCom - BecoCom
Demarcation Point "A", the [**], and the FiveCom - BecoCom Demarcation Point "B"
that does not meet the Specifications, plus (b) [**] and the NEESCom - BecoCom
Demarcation Point, that does not meet the Specifications. As an illustration, if
none of the FiveCom Fibers described above meet the Specifications, BecoCom will
pay FiveCom [**] per day. Notwithstanding the foregoing, BecoCom shall not be
obligated to make the payment provided in the preceding sentence to the extent
that FiveCom fails, at any time when such payment would otherwise be due, to
have completed installation of, and have available for use or use by others, an
equivalent amount of the non-optronic portion of the FiveCom Portion as
discussed in Section 4.5 above, or otherwise fails to use its best commercial
efforts to install the optronic portion of the FiveCom Portion, as described in
Section 2. If the delay in providing at least the number of fibers required for

          Confidential Materials omitted and filed separately with the
        Securities and Exchange Commission. Asterisks denote omissions.


that any such termination shall not affect whatever rights either party had
obtained under this Agreement prior to such termination.

         5.3 Testing. The Completion Date shall be deemed to be the date that
BecoCom has installed the Cable called for in Section 4.1 along the BecoCom
Portion of the Route as described in that Section and that (a) at least [**] of
the [**] fibers in the BecoCom Portion between the FiveCom - BecoCom Demarcation
Point "A", the [**], and the FiveCom - BecoCom Demarcation Point "B" meet the
Specifications, and (b) at least [**] of the [**] fibers in the BecoCom Portion
between [**] and the NEES Com - BecoCom Demarcation Point meet the
Specifications ("Minimum Number of Fibers"). Compliance of the FiveCom Fibers
with the Specifications shall be determined specifically by testing in
accordance with the Acceptance Test Plan ("ATP") described in Exhibit 5.3.
BecoCom shall provide FiveCom with written notice of the commencement of the
acceptance testing at least [**] prior to that commencement. Subject to the
restrictions, terms and conditions of the Utility Agreement, FiveCom shall have
the right to have representatives present to observe any tests conducted by
BecoCom as part of the ATP. BecoCom shall be responsible for testing the BecoCom
Portion of the FiveCom Network, and FiveCom shall be responsible for testing the
entire FiveCom Network on an end-to-end basis. If the end-to-end test reveals
that a particular piece of equipment (including fiber strands and splices) fails
to satisfy the Specifications, the party responsible for such installation shall
be responsible for fixing it. The failure of FiveCom to complete satisfactorily
the end-to-end testing of the entire FiveCom Network shall not relieve FiveCom
of its obligations to make payment under Section 8, unless the failure is due to
a breach by BecoCom of this Agreement.

         5.4 Review of the Test Results. Within [**] of the conclusion of the
ATP, BecoCom shall provide FiveCom with test results certified by BecoCom in
accordance with the ATP and pursuant to Exhibit 4.2, Item 3.0. If the certified
test results establish that the FiveCom Fibers satisfy the Specifications, and
if FiveCom shall not object to such conclusion within [**] of its receipt of
such results, then the date of the completion of the ATP testing shall be deemed
to be the Completion Date. If FiveCom shall so object, it shall provide to
BecoCom sufficient technical details of its objection within such [**] period.
If BecoCom disagrees with FiveCom's objections, then the dispute shall be
submitted to the neutral expert mutually agreed by the Parties for resolution
within [**], or if the Parties cannot agree on a neutral expert, then the
dispute will be resolved by arbitration pursuant to Section 23. The neutral
expert or arbitration panel, as the case may be, shall resolve the dispute and
determine the Completion Date, including whether or not any amount is payable
pursuant to Section 5.2 or Section 8. Use of the FiveCom Fibers, or any subset
thereof, by FiveCom for any purpose other than testing as provided herein shall
constitute acceptance of

          Confidential Materials omitted and filed separately with the
        Securities and Exchange Commission. Asterisks denote omissions.


the fibers so used by FiveCom, and the Completion Date shall be deemed to have
occurred with respect to such fibers.

         5.5 Completion of Remaining Fibers. In the event that the Completion
Date is declared based on BecoCom's delivery of the Minimum Number of Fibers,
but less than all [**] FiveCom Fibers described in Section 4.1, then, if
requested by FiveCom, BecoCom shall use commercially reasonable efforts to
ensure that FiveCom has access to capacity equal to the full number of fiber
optic strands described in Section 4.1 that meet the Specifications at the
earliest practicable date after the Completion Date.

6.       DELIVERABLES.

         6.1 Description. Within the time periods specified in Section 6.2,
BecoCom shall deliver to FiveCom the items listed in Exhibit 6.1 (the
"Deliverables").

         section 5, FiveCom shall pay to BecoCom the following amount [**]: The
         sum of (i) [**] for each of the [**] fibers available in compliance
         with this Agreement for FiveCom use between the FiveCom - BecoCom
         Demarcation Point "A", the [**], and the FiveCom - BecoCom Demarcation
         Point "B", plus (ii) [**] for each of the [**] fibers available in
         compliance with this Agreement for FiveCom use between [**] and the
         NEES Com - BecoCom Demarcation Point, plus (iii) the Excess Location
         Fee provided for in Section 8.3, Sales Taxes provided for in Section

the determination that FiveCom has, or had, at the relevant time, Third Party
customers who would use, or would have used, the fibers, but for their failure
to comply with the Specifications, or (ii) the determination that FiveCom would
have received revenues from such fibers, but for their failure to comply with
the Specifications. Nothing herein shall affect any obligation of BecoCom with
respect to any fibers that do not meet Specifications pursuant to any other
provision of this Agreement.

         8.2 [**] Payments. In addition to the payments called for by Section
8.1, FiveCom shall pay to BecoCom [**] as follows:

                  reimburse BecoCom for its costs of such audits, unless the
                  audit reveals a discrepancy in the amount of [**] determined
                  by FiveCom is less than [**], in which case BecoCom shall pay
                  for the audit. In addition, subject to a mutually agreed
                  confidentiality agreement, the respective presidents of NEES

                  purpose of [**] under this Section 8.2, and shall not create

         9.2      Maintenance. (a) Emergency Maintenance. As provided in Exhibit
                  9.2(a), BecoCom shall use best commercial efforts to respond
                  within [**] to any failure, interruption or impairment in the
                  operation of the FiveCom Fibers after receiving a report from
                  FiveCom of any such failure, interruption or impairment.
                  Subject to the restrictions, terms and conditions of the
                  Utility Agreement, BecoCom shall use best commercial efforts
                  to correct any failure, interruption or impairment in the
                  operation of the FiveCom Fibers as expeditiously as possible
                  in accordance with the procedures set forth in Exhibit 9.2(a).

                  obligation to replace only applies to the number of FiveCom
                  Fibers that meet the Specifications on the Completion Date

                  Provision for any federal, state or local taxes and the Tax
                  Impact of such taxes incurred by BecoCom as a result of
                  FiveCom's payment of FiveCom's share shall be added to
                  FiveCom's share. For purposes of this Agreement, "Tax Impact"
                  means federal, state and local income taxes incurred on
                  reimbursement of federal, state and local income taxes. This
                  amount shall be reduced by the net present value of tax
                  benefits receivable on future tax depreciation deductions for
                  the replacement fibers. In addition, this amount shall be
                  reduced by the tax benefit due to any acceleration of tax
                  depreciation deductions for FiveCom Fibers replaced. FiveCom
                  shall have the option of not replacing the failed fibers, or
                  of terminating the Agreement prior to the end of the Initial
                  Term of this Agreement in lieu of sharing in the cost of
                  replacing the FiveCom Fibers; provided that FiveCom may
                  exercise this right to terminate only if, prior to any
                  replacement, less than the Minimum Number of Fibers meet the
                  Specifications.

         (c)      After Initial Term or Expansion of Cable. If FiveCom and
                  BecoCom mutually agree and if permitted under the Utility
                  Agreement, BecoCom may provide replacement fiber after the
                  Initial Term or may replace all or a portion of the existing
                  Cable with a new cable having an increased number of fiber
                  optical strands for FiveCom's use; provided that such
                  replacement shall be installed at FiveCom's

                  incremental cost (including provision for any related federal,
                  state, or local taxes on a grossed-up basis) and under terms
                  mutually agreed to by FiveCom and BecoCom.

Structures shall be held by BecoCom or its Affiliates. FiveCom's rights
hereunder shall be deemed an Indefeasible license or Right to Use (IRU) the
FiveCom Fibers, subject to the terms of this Agreement. Neither the IRU nor
other provision of FiveCom Fibers or any other facilities or services by BecoCom

of federal, state and local income taxes. The Parties agree they will file all
income tax returns and otherwise take all actions with respect to income taxes
in a manner consistent with the foregoing.

         11.4     Sales Taxes.

         (a)      BecoCom will be responsible for paying any and all existing or

                  imposed or levied by any federal, state or local taxing
                  authority on purchases of materials and/or equipment for use
                  in construction of the Cable. FiveCom agrees to cooperate at
                  BecoCom's expense in any proper claim of exemption or
                  exclusion from such taxes which BecoCom may assert for such
                  purchase; such cooperation shall include (but not be limited
                  to) providing any required certificates and/or other
                  documentation of such purchases to which it may be a party.
                  FiveCom agrees to provide BecoCom with all documentation of
                  any such purchases to which it may be a party and agrees that

                  taxes without such documentation.

         (b)      FiveCom will be responsible for paying any and all existing or
                  future sales, excise or other transfer or transactional taxes
                  imposed or levied by any federal, state or local taxing

                  BecoCom agrees to cooperate at FiveCom's expense in any proper

in, or additions to, any existing federal, state or local excise, franchise, ad
valorem, property or similar taxes, payments or payments in kind, or any similar
fees such as franchise fees, license fees or user fees imposed on BecoCom, which
increase or addition is attributable to the presence of FiveCom Fibers on
Structures, Cable Accessories, and equipment. BecoCom agrees to cooperate with
FiveCom to the extent FiveCom seeks to contest, by appropriate legal process,
the assessment by the relevant governmental authority of any tax, fee or other
charge for which FiveCom becomes liable hereunder; provided that such obligation
to cooperate does not include the obligation of BecoCom (1) to participate in
any tax contest on FiveCom's behalf; (2) to ensure that FiveCom has the right to
initiate or to participate in such tax contest; or (3) to ensure that its

a timely manner to the applicable taxing authorities or governmental agencies

shall be liable to the other for any indirect, special, punitive, or
consequential damages, or any lost business damages in the nature of lost
revenues or profits (including, but not limited to any claim from any customer

omissions may affect the construction, operation or use of the FiveCom Fibers.

                  phenomena), equipment failure, war, embargo, riot or
                  insurrection, acts of God or public enemy, restraint or
                  hindrance by any governmental or regulatory authority
                  (including, without limitation, denial of necessary permits or
                  licenses, imposition of commercially unreasonable conditions,
                  delays or other failures to act of or by such authorities,
                  except when the result of a failure to use best commercial
                  efforts by the Party claiming force majeure); or

delay has ceased. FiveCom shall promptly notify BecoCom of any delay
constituting a Force Majeure Event, and its effect on the performance by

FiveCom to BecoCom under section 8.1, shall be suspended for so long as such
Force Majeure Event continues. At the conclusion of a Force Majeure Event, the
period of time during which performance was so suspended shall be added to the
dates, schedules and other performance-related matters under this Agreement. If,
notwithstanding the parties' efforts under Section 14.2, the Force Majeure Event
continues unabated for more than six (6) months, the Party whose performance is
unaffected by the Force Majeure Event shall have the option to terminate this
Agreement.

         14.4     Labor Disputes.

         (a)      If an actual or potential labor dispute delays or threatens to
                  delay a Party's performance, that Party shall immediately
                  notify the other Party in writing, stating all relevant
                  information concerning the dispute and its background. The
                  Parties shall include this paragraph in any subcontract for
                  the services (with a contractor other than an Affiliate) if a
                  labor dispute thereunder might delay the timely performance of
                  the services, and each such subcontract shall provide that if
                  any actual or potential labor dispute occurs, the lower-tier
                  subcontractor shall immediately notify the Parties of all
                  relevant information concerning such dispute.

         (b)      If BecoCom reasonably determines that FiveCom activities
                  pursuant to this Agreement in or near the Route are causing or
                  will cause labor difficulties for BecoCom or its Affiliates,
                  FiveCom shall discontinue those activities until the labor
                  difficulties have been resolved; provided, however, that in
                  any such event and notwithstanding any other provision of this
                  Agreement, BecoCom shall during the period of such labor
                  difficulties perform, or cause to have performed, at FiveCom's
                  expense (utilizing the lowest market rate reasonably
                  available) any such activities to the extent reasonably
                  necessary to the operation and maintenance of the FiveCom
                  Network or any portion thereof.

         (c)      by either Party if the other Party (a) consents to the
                  appointment of, or is taken in possession by, a receiver,
                  trustee, custodian or liquidator of a substantial part of its
                  assets, (b) files a bankruptcy petition in any bankruptcy
                  court proceeding, (c) answers, consents or seeks relief under

         (d)      by either Party if the other Party fails to pay amounts due
                  when they become due and payable under this Agreement where

                  Party is in arrears more than [**] past the due date
                  provided BecoCom has provided [**] notice prior to such
                  termination;

         (e)      by either Party if the other Party makes any representation or
                  warranty in this Agreement, which is incorrect and has or may
                  have a material and adverse effect on the other Party (as
                  reasonably determined by such non-breaching Party), and such
                  incorrect representation or warranty shall continue unremedied
                  for a period of [**] after written notice of such incorrect
                  representation or warranty (except only where this Agreement
                  specifically provides additional time and/or other options or
                  remedies for any such failure; or, with respect to an
                  obligation that is susceptible of cure within a reasonable
                  time period so long as such Party is using best commercial
                  efforts to promptly cure).

         17.2     Termination of a Portion of the Route.  Any portion of the
                  Route may be terminated:

         (a)      by BecoCom, without liability except for its obligations under
                  section 17.3 and at any time, upon reasonable notice, to the
                  extent BecoCom is no longer authorized under the Utility
                  Agreement to maintain, operate, or grant the right to use the
                  Cable, Cable Accessories or Structures within the portion of
                  the Route.

         (b)      by BecoCom, without liability except for its obligations under
                  section 17.3 and at any time, if it cannot maintain any of the
                  regulatory approvals needed to perform BecoCom's obligations
                  under this Agreement with respect to such portion of the Route
                  or it is prohibited by a governmental authority from
                  performing such obligations with respect to a portion of the
                  Route, provided that BecoCom, to the extent reasonably
                  practicable, has provided FiveCom prompt notice of any
                  government proceedings that would require the termination of
                  the portion of the Route and has cooperated with FiveCom's
                  rights to participate in any such proceedings.

         17.3 Alternate Capacity or Facilities. If a Portion of the Route is
terminated pursuant to Section 17.2, BecoCom shall use its best commercial
efforts to [**]; provided that FiveCom may [**] after termination of the portion

         17.4     Effect of Termination.

                  (a)      FiveCom shall not be entitled to, nor shall BecoCom
                           be liable for, any refunds of amounts paid to
                           BecoCom, by reason of early termination of this
                           Agreement under Section 17.1, or termination of a
                           portion of the Route under Section 17.2, unless
                           termination is due to a breach of this Agreement by
                           BecoCom.

                  (b)      Except as otherwise provided in this Agreement, a
                           decision to terminate this Agreement under Sections
                           17.1 or 17.2 shall not preclude the terminating Party
                           or the other Party from pursuing any other legal,
                           equitable or administrative rights and remedies;
                           provided, however, that such rights and remedies
                           shall at all times be subject to limitations and
                           indemnifications under Section 12.

                  (c)      Upon termination of this Agreement or portion of the
                           Route under Sections 17.1 or 17.2, the right to use
                           the FiveCom Fibers or the terminated portion thereof,
                           as the case may be, shall revert to BecoCom, at no
                           additional cost to BecoCom, in accordance with
                           Section 11.7.

18.      CONDEMNATION.

         18.1 Condemnation of FiveCom Fibers. In the event any portion of the
FiveCom Fibers, or the rights-of-way in or upon which they shall have been
installed, become the subject of a condemnation proceeding by any governmental
agency or other party cloaked with the power of eminent domain for public
purpose or use, and such action precludes the continued use of the FiveCom
Fibers by FiveCom, as contemplated by this Agreement, then and in such event, it
is agreed that BecoCom shall use best commercial efforts to [**]. To the extent
allowed by law and subject to the restrictions, terms and conditions in the
Utility Agreement, FiveCom shall be [**].

         18.2 Condemnation of Other Portions of the FiveCom Network. In the
event any portion of the FiveCom Network other than the FiveCom Fibers, or the
rights-of-way in or upon which the FiveCom Network shall have been installed,
become the subject of a condemnation proceeding by any governmental agency or
other party cloaked with the power of eminent domain for public purpose or use,
then and in such event, it is agreed that FiveCom shall use best commercial
efforts to obtain an alternative route over which the FiveCom Network may be
relocated, at no cost to BecoCom to ensure that FiveCom can maintain its then
existing customers and level of gross revenues.

          Confidential Materials omitted and filed separately with the
        Securities and Exchange Commission. Asterisks denote omissions.


To the extent that FiveCom Fibers can still be used to serve FiveCom's
customers, FiveCom shall continue to use the FiveCom Fibers and shall continue
to be obligated under terms of this Agreement, including without limitation its
obligations to pay the fees provided under Section 8; provided, however, that
if, after the first year in the Term of this Agreement, FiveCom's gross revenues
derived from the FiveCom Network in a [**] and subject to sharing under Section
8.2 decrease as a result of the condemnation, by [**] below the level of gross
revenues in the prior [**], BecoCom shall have the option to provide FiveCom
notice that FiveCom will have [**] to secure alternate capacity or facilities to
restore its gross revenues, or the Agreement will be terminated.

         18.3 Notice; No Sale. Upon its receipt of a formal notice of
condemnation or taking, the condemnee Party shall notify the other Party
immediately of any condemnation proceeding. The condemnee Party shall also
notify the other Party of any similar threatened condemnation proceeding, and
agrees not to sell any property associated with or affecting the FiveCom Fibers
or FiveCom Network to such acquiring agency, authority or other party in lieu of
condemnation without prior written notice to the other Party.

19.      RELATED AGREEMENTS.

         19.1 NEES Com/FiveCom Agreement. Simultaneously with the execution of
this Agreement, FiveCom is entering into a similar agreement with NEESCom (the
"NEESCom Agreement") pursuant to which FiveCom is leasing fiber optic facilities
from [**]. The Parties hereby agree that FiveCom's obligations under this
Agreement are not conditioned upon the execution of, compliance with, or
continued enforceability of the NEESCom Agreement; provided, however, that the
Parties agree to make appropriate changes to the revenue sharing in Section 8.2
of this Agreement in the event that the NEESCom Agreement is not executed, is
terminated, or ceases to be enforceable.

         19.2 Initial Unavailability. If NEESCom shall fail to complete the
installation of fiber optic cable (either on a timely basis or at all) as
required by the NEESCom Agreement, FiveCom's obligation to make payments under
Section 8 of this Agreement shall nevertheless commence on the Completion Date;
provided, however, that if the Completion Date has occurred under this Agreement
and the fiber optic cable under the NEESCom Agreement remains uncompleted for a
period of [**] after the Completion Date hereunder, BecoCom shall have the
option to provide FiveCom notice that FiveCom will have [**] to secure alternate
capacity or facilities [**], or this Agreement will be terminated.

         19.3 Subsequent Unavailability. If, following the Completion Date, any
portion of the FiveCom Network other than the FiveCom Fibers shall become

unavailable to FiveCom, FiveCom shall continue to be obligated under this
Agreement. In particular, to the extent that FiveCom Fibers can still be used to
serve FiveCom's customers, FiveCom shall continue to use the FiveCom Fibers and
to be obligated to pay the fees provided under Section 8; provided, however,
that if, after the first year of the Term of this Agreement, [**] derived from
the FiveCom Network in a [**] of the other portion of the FiveCom Network by
[**] in the prior [**], BecoCom shall have the option to provide FiveCom notice
that FiveCom will have [**] to secure alternate capacity or facilities [**] or
the Agreement will be terminated.

20.      PROPRIETARY INFORMATION.

         20.1 Obligation to Maintain as Confidential. Each Party acknowledges
that in the course of the performance of this Agreement it may have access to
information that the other Party considers proprietary ("Proprietary
Information"). Propriety Information shall be marked as proprietary with an
appropriate legend, marking, stamp or other obvious written identification prior
to disclosure. All Proprietary Information in tangible form of expression which
has been delivered (or thereafter created by copy or reproduction pursuant to
this Agreement) shall be and remain the property of the person which is
disclosing such Proprietary Information (the "Disclosing Party").

         (a)      This Agreement shall be treated as Proprietary Information by
                  the parties,

         (b)      Each party will provide the other party advance notice of any
                  compelled disclosure of this Agreement by legal or regulatory
                  process, including, but not limited to, disclosure to the
                  Securities and Exchange Commission.

         20.2     Obligations Concerning Proprietary Information.

         (a)      General Restrictions. Upon receiving Proprietary Information,
                  the Party receiving the Proprietary Information ("Receiving
                  Party") shall keep in strict confidence and not disclose to
                  any person (with the exception of employees, officers,
                  directors, agents or representatives, and Affiliates of the
                  Receiving Party, to the extent each such person or entity has
                  a need to know in connection herewith) any of the Disclosing
                  Party's Proprietary Information, except as otherwise provided
                  by the terms and conditions of this Agreement. The Receiving
                  Party shall not use such Proprietary Information except for
                  the purposes identified herein without the prior written
                  approval of the Disclosing Party. The Receiving Party 






                                      -29-
<PAGE>

                  shall be solely liable for any breach of this Section 20.2 to
                  the extent caused by its, or its Affiliates', employees,
                  officers, directors, agents or representatives.

         (b)      Additional Marking Requirements. In the event either Party
                  discloses its Proprietary Information to the other Party
                  unmarked or in oral or visual form, the Disclosing Party shall
                  notify the Receiving Party in writing that such Information is
                  deemed proprietary within forty-eight (48) hours of its
                  disclosure. Such Proprietary Information shall be treated in
                  the manner set forth above from the date such written notice
                  is received.

         (c)      Exceptions. The Receiving Party shall not be precluded from,
                  nor liable for, disclosure or use of any Proprietary
                  Information if:

                           (i)      the Proprietary Information is in or enters
                                    the public domain, other than by a breach of
                                    this Agreement;

                           (ii)     the Proprietary Information is known to the
                                    Receiving Party at the time of first
                                    receipt, or thereafter becomes known to the
                                    Receiving Party prior to or subsequent to
                                    such disclosure without similar restrictions
                                    from a source other than the Disclosing
                                    Party, as evidenced by written records;

                           (iii)    the Proprietary Information is developed by
                                    the Receiving Party independently of any
                                    disclosure under this Agreement as evidenced
                                    by written records;

                           (iv)     the Proprietary Information is disclosed
                                    more than five (5) years after the date of
                                    first receipt of the disclosed Proprietary
                                    Information; or five (5) years after the
                                    Term whichever occurs later;

                           (v)      disclosure of the Proprietary Information is
                                    compelled by a government authority,
                                    including, but not limited to any court or
                                    regulatory body, provided that the Receiving
                                    Party has used its best efforts to resist
                                    disclosure of, redact or otherwise protect
                                    the confidentiality of the economic terms of
                                    this Agreement, including, without
                                    limitation, Section 8.;

                           (vi)     the Disclosing Party consents to the
                                    disclosure or use of the Proprietary
                                    Information; or

          Confidential Materials omitted and filed separately with the
        Securities and Exchange Commission. Asterisks denote omissions.


                           (vii)    the Receiving Party has a reasonable belief
                                    that disclosure of the Proprietary
                                    Information is necessary for public safety
                                    reasons and has attempted to provide as much
                                    advance notice of the disclosure as is
                                    practicable.

         (d)      Disclosures. The disclosure of Proprietary Information
                  hereunder shall not be construed as granting any right of
                  ownership in said Proprietary Information.

21.      DEFAULT.

         21.1 By FiveCom. A breach by FiveCom of any of its representations,
covenants or obligations under this Agreement which is not cured as provided
herein shall constitute a Default by FiveCom. FiveCom shall not be in Default
unless and until BecoCom shall have given FiveCom written notice of such breach
and FiveCom shall have failed to cure the same within [**] after receipt of such
notice; provided, however, that the foregoing notice and cure requirement shall
not apply to FiveCom's obligation to make payments in a timely manner as
provided under Sections 8.2(e) and 8.4 hereof. Where any breach, other than a
breach of Section 8.2(e) and 8.4, cannot reasonably be cured within such [**],
if FiveCom shall proceed promptly to cure the same and prosecute such curing
with due diligence, the time for curing such breach shall be extended for such
period of time as may be necessary to complete such curing. Upon the failure by
FiveCom to timely cure any such breach after notice thereof from BecoCom,
BecoCom shall have the right, in its sole discretion, to take such action as it
may determine to be necessary to cure the breach, or to terminate this Agreement
upon written notice to FiveCom. The Parties intend that the notice and cure
provisions of this Section 21.1 apply only to the extent specific notice and
cure provisions are not provided elsewhere in this Agreement.

         21.2 By BecoCom. A breach by BecoCom of any of its representations,
covenants or obligations under this Agreement which is not cured as provided
herein shall constitute a Default by BecoCom. BecoCom shall not be in Default
unless and until FiveCom shall have given BecoCom's written notice of such
breach and BecoCom shall have failed to cure the same within [**] after receipt
of such notice; provided, however, that where such breach cannot reasonably be
cured within such [**] period, if BecoCom shall proceed promptly to cure the
same and prosecute such curing with due diligence, the time for curing such
breach shall be extended for such period of time as may be necessary to complete
such curing. Upon the failure by BecoCom to timely cure any such breach after
notice thereof from FiveCom, FiveCom shall have the right, in its sole
discretion, to take such action as it may determine to be necessary to cure the
breach, or to terminate this Agreement upon written notice to BecoCom; provided
that the foregoing right to self-help shall not be





                                      -31-
<PAGE>

construed to allow FiveCom or its agents or contractors access to the BecoCom
Portion of the Cable, Cable Accessories and Structures. The Parties intend that
the notice and cure provisions of this Section 21.2 apply only to the extent
specific notice and cure provisions are not provided elsewhere in this 
Agreement.

Agreement and shall not relieve either Party of any obligations it may otherwise
have to continue performance in accordance with the provisions of this
Agreement.
