<PAGE>

5.3 ADDITIONAL ROUTE SEGMENTS DESIGNATED BY GRANTEE. If the Grantee wishes to
extend the Route by installing Cable on transmission facilities marked in red on
Exhibit 5.3 (Network Expansion) or if any Route Segment requires material
modifications or unusual expense to make it available for the Cable or if
Grantor withdraws Route Segments pursuant to Section 5.2 or Section 21.4, then
the Grantee shall have the right, subject to the Grantor's approval, to
designate additional Route Segments, or an alternative path for the Cable on
Structures or property of the Grantor by submitting a request in the form of
Exhibit 11.1. The Grantor shall not withhold its approval of such additional
Route Segments unless such additional Segments would materially adversely affect
the Grantor's ability to provide reliable electric service, cause or create
safety problems or not be feasible for structural reasons. Subsequent to the
date of execution of this Amended and Restated Agreement, the rights and
obligations of the parties set forth in this Section 5.3 shall be governed by
the 2002 Phase 2 Agreement.

5.4 COST AND MEANS OF RIGHT OF WAY ACQUISITIONS. The Grantee shall be
responsible for, and the Grantor shall cooperate in, the acquisition of any
easement or right-of-way rights that may be required in order to permit (1) the
installation, operation and maintenance of the Cable on the Route or (ii) the
use of the NEON Network fibers by Grantee. New easements obtained by Grantee
shall be assigned to Grantor, if possible. 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 the NEON Network fibers by Grantee, then any required
condemnation action shall be brought by Grantee in its own behalf, if such
action is available to Grantee. Any easement or right obtained by the Grantee by
using the power of eminent domain shall be subsequent and subordinate to any
existing rights of the Grantor. Except in the case of condemnation by Grantee,
Grantor shall exert its best efforts to minimize the cost of such additional
land or rights in land. In the event that additional rights are required by both
parties the cost of the acquisition of such additional rights shall be shared by
the parties pro rata based on the number of fibers controlled by each party.
This Section is not intended as an acknowledgment by either party that any such
acquisition of additional rights is required but only to allocate the
responsibility for such acquisition if required.

5.5 GRANTEE'S RIGHT TO BUILD AND CONNECT THIRD PARTY SEGMENTS. In the event that
the Grantor (1) does not have Structures available to replace Route Segments not
available for any reason to the Grantee or (ii) does not provide such Structures
at the request of the Grantee, the Grantee shall have the right to build or
otherwise obtain such Structures from Third Parties, at the Grantee's sole cost
and expense. The Grantee may connect such Third Party facilities to the Route
Segments and Cable subject to the approval by Grantor of Grantee's connection
plans. The work to connect such Third Party facilities located on the Grantor's
property shall be performed by the Grantor. The provisions of the last two
sentences of Section 6.1 shall apply to this work to be performed by the
Grantor. Grantee shall pay all of Grantor's Actual Costs to review these
connection plans and to oversee the construction of such connections. If the
Grantee interconnects Third Party facilities to the Cable or Structures, Grantee
shall, upon Grantor's request, use its best efforts to provide the right to use
up to 12 singlemode fibers on such Third Party's facilities to maintain the
continuity of NUNet within Grantor's Territory and up to eight singlemode fibers
outside Grantor's Territory on terms no less favorable than those provided
Grantee for the NEON Network. Subsequent to the date of execution of this
Amended and Restated Agreement, the rights and obligations of the parties set
forth in this Section 5.5 shall be governed by the 2002 Phase 2 Agreement.

will be the beneficial owner. Accordingly, Grantee shall for tax purposes
account for such property 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. Grantor agrees that it
will not, for tax purposes, account for the property associated with the NEON
Network fibers 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.

15.2 REVERSION OF BENEFICIAL OWNERSHIP. Grantee's right of use under Section 4
of this Agreement and beneficial ownership of the NEON Network shall revert to
the Grantor apon termination of this Agreement or of any applicable Route

16. USE OF THE CABLE BY GRANTOR

16.1 FIBERS AND USE. The Grantee shall provide not less than 12 usable
singlemode fibers in the Cable for the unimpeded and unrestricted use by
Grantor, provided however that the requirement of usability shall not apply to
any fibers located upon a Route Segment as to which the Term has expired. The
Grantor shall use these 12 singlemode fibers exclusively for the Grantor's own
business purpose and other uses permitted by this Section 16.1, which shall
include but not be limited to the right of the Grantor to assign any number of
the 12 fibers, or resell capacity on any of the 12 fibers, provided however,
that such right to assign or resell said capacity is subject to Grantee's
indefeasible right to use certain NUNet fibers, its IRU Option and its IRU ROFR,
as defined in Sections 4. IA through 4.1 C and the Non-Compete Section 26.3
hereof.

Notwithstanding the foregoing, in times of emergencies affecting the Grantor's
other telecommunications networks, the Grantor shall have the right to use the
12 singlemode fibers not previously provided to Grantee under the IRU ROFR or
IRU Option or otherwise acquired by Grantee for any purpose until alternative
arrangements can be made. If the Grantor violates the provisions of this Section
16.1 and fails to cease such violation within 90 days following written notice
of such violation by the Grantee, the Grantor's rights to use the fibers
involved in such violation shall cease and the Grantee shall then have the right
to use such fibers for its own business purpose.

16.2 OPTION TO PURCHASE ADDITIONAL FIBERS. The Grantor may purchase, if mutually
acceptable terms can be agreed upon between Grantee and the Grantor, additional
singlemode fibers from the Grantee at a price that is mutually acceptable.

this Agreement, provide Grantor with commercial telecommunication services into
all locations served by Grantee's networks in the service area at Grantee's
Actual Cost for any incremental labor and provisioning equipment required for
the service being requested and, if provided using fibers other than Grantor's
12, Grantor shall also pay, without duplication of such actual cost, , the then
lowest commercial price for such service(s) that Grantee offers the same or
similar services to its largest customers ("Favored Customer Rates").

16.4 SPACE IN GRANTEE'S LOCATIONS. Where available and requested by Grantor,
Grantee shall, so long as Grantor is not in breach of this Agreement, provide or
cause to be provided Grantor Space in the Grantee offices and other common
access areas of Grantee facilities along the Route Segments in New Buildings or
buildings adjacent thereto, adequate in each case to permit Grantor to install
racks of its optronics, multiplex and associated equipment used to equip NUNet
and to interconnect NUNet with the NEON Network. Unless otherwise agreed,
Grantor Space will comply with power, ground, physical and environmental
requirements of the Grantee technical publications. Such Grantor Space shall be
used by Grantor to house Grantor Equipment necessary to permit the use of the
NUNet and interconnection with the Grantor's networks. Unless otherwise agreed,
Grantor Space in a Grantee facility other than a New Building, or buildings
adjacent thereto, shall be in a common access area of such facility, and to the
extent reasonably practicable, Grantor Space in a New Building shall be separate
from any area containing Grantee's Equipment. Grantee shall provide Grantor
Space in the common access areas of Grantee facilities at the then prevailing
rate for such space according to Grantee's tariff.

17. CASUALTY

17.1 CABLE DAMAGE. If any portion of the Cable is damaged or destroyed by
casualty at any time during the Term each party shall pay a share of the cost of
repair, restoration or replacement based on the pro rata percentage of fibers,
NUNet and NEON Network, contained in the Cable. With respect to the Route
Segment on which such portion of the Cable is installed, the Grantee shall have
the option of having the Grantor repair, restore, or replace such portion of the
Cable (and the Grantee shall reimburse Grantor's Actual Cost of doing so) or
terminating that Route Segment. Unless Grantee notifies Grantor of its election
to terminate that Route Segment within 12 business days of the casualty, Grantee
shall be deemed to have elected repair, restoration and replacement of the
Cable. If Grantee elects to terminate such Route Segment as set forth in the
preceding sentence, the NEON Network fibers upon such portion of the Route
Segment so effected, shall be available for use by Grantor and Grantee shall
assign, at no cost to Grantor, all its rights and title to all New Buildings and
Equipment on such Route Segments so effected immediately thereafter.

of Canada which share a border with any of those States if the Grantor
contributed in a material way to the Grantee's obtaining such route segments.
The one-time payment will be paid upon execution of an agreement with such Third
Party but the annual fee will not be due until the sooner of the Activation Date
or the In-Service Date of such route segments. (Grantee seeks route segments
into New York from Connecticut; into Rhode Island from Connecticut and
Massachusetts; into Vermont from Massachusetts, New Hampshire, New York, and
Canada; and into Maine from New Hampshire and Canada.).

         PROVIDED, HOWEVER, that Grantor hereby agrees to accept from the
Grantee $3,432,657 (the "Fiber Payments") in full and complete satisfaction of
any and all amounts due and owing by the Grantee to the Grantor hereunder
through June 25, 2002, with the exception of any amounts owing pursuant to
section 32.2 hereof and section 32.2 of the 2002 Phase 2 Agreement, and Grantor
and Grantee agree that the Fiber Payments shall be offset against the
acquisition price of the common stock of NEON Communications, Inc, pursuant to
the terms of the Common Stock Purchase Agreement.

         (c) As to the indefeasible rights of use in the Additional NLJNet
fibers granted to Grantee pursuant to Section 4.1 A hereof, Grantee shall also
pay an annual fee (the "IRU Fee") as follows:

                                       20
<PAGE>

         $125,000 per annum, as adjusted pursuant to Section 22.2 hereof, for
the term of this Agreement as it may be extended, payable in advance on the
first business day of each year. For calendar year ending December 31, 2002, the
fee shall be pro rated for the actual number of days remaining in the year from
date hereof through December 31, 2002 and such fee for calendar year 2002 shall
payable upon the execution of this Amendment.

22.2 CPI ADIUSTMENTS. (a) The Annual Fee shall be adjusted annually from the
Effective Date by an escalation factor equal to changes in the Consumer Price
Index All Urban (CPI-U) published by the US Department of Labor, Bureau of Labor
Statistics, which shall be calculated each October based on changes in the CPI-U
from the previous October. In no instance shall the CPI-U change be applied if
it results in a smaller payment than the previous year's payment. As to any
period during which fees have been waived, the CPI-U shall accrue to the rate
during such waiver period.

         (b) The IRU Fee shall be adjusted annually from the date hereof by an
escalation factor equal to changes in the Consumer Price Index All Urban (CPI-U)
published by the US Department of Labor, Bureau of Labor Statistics, which shall
be calculated each October based on changes in the CPI-U from the previous
October. In no instance shall the CPI-U change be applied if it results in a
smaller payment than the previous year's payment. As to any period during which
fees have been waived, the CPI-U shall accrue to the rate during such waiver
period.

22.3 ADDITIONAL AMOUNTS. In addition to the amounts due and payable pursuant to
Section 22.1, as adjusted pursuant to Section 22.2, Grantee shall pay Grantor an
amount equivalent to 2% of Grantee's gross revenues realized from the NEON
Network on Grantor's Structures. The payment shall be made each and every year
that Grantee's gross revenues realized from the NEON Network on Grantor's
Structures exceed $15 million. For purposes of this section Grantee's gross
revenues realized from the NEON Network on Grantor's Structures shall be the
ratio of route miles of the NEON Network on Grantor's Structures to Grantee's
Total Route Miles applied to Grantee's annual gross revenues, as of, in each
case, December 31 of each year. This calculation is set forth in the following
formula: "If ((route miles of the NEON Network on Grantor's Structures divided
by Grantee's Total Route Miles) times Grantee's annual gross revenues) is more
than $15,000,000, then Payment will equal ((route miles of the NEON Network on
Grantor's Structures divided by Grantee's Total Route Miles) times Grantee's
annual gross revenues) times 0.02". Payment will be due no later than July 1 of
the year following the computation year. The parties will agree to revisit this
methodology in the event Grantee acquires the ability to track revenues by fiber
route or combines with another telecommunications company.

22.4 WHEN DUE. All Annual Fees shall be paid on January 1st of each year. All
pro-rata payments made during the year shall be based on this date. All payments
shall be paid within 30 days of invoicing.

22.5 INITIAL ANNUAL FEE. Unless otherwise waived according to the provisions of
22.1(b)(i), 22.1(b)(iv) or otherwise, the initial Annual Fee payment will be due
and payable within 30 days after preliminary engineering work has been accepted
by both parties and shall be based upon the estimated number of duct feet and
aerial feet to be utilized by Grantee over the remainder of the calendar year.

23. FORCE MAJEURE

23.1 OPTIONAL TERMINATION. Should any of the Force Majeure Events defined below
occur and should the Grantor determine that as a direct or indirect result
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 any portion of the Route Segments and the Cable 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 obtain
alternative means of providing service to customers, but neither party shall
have an obligation to do so. A Force Majeure Event shall include fire, flood,
strike or other labor difficulty, natural disasters, acts of God or public
enemy, (restraint or hindrance by any governmental authority), war,
insurrection, not, action of any regulating authorities; or institution of
litigation by any Third Party, or any other causes of any nature reasonably
beyond the control of either party which would have a material adverse effect on
the subject matter of this Agreement. Financial difficulties, or events
resulting from financial difficulties, shall not be considered a Force Majeure
Event.

23.2 SUSPENSION PENDING FORCE MAJEURE. If a Force Majeure Event should occur

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 has been or is
subsequently made public by the other party, is independently developed by such
party, disclosed pursuant to order by a court or government agency, or if the
other party gives its express, prior written consent to the disclosure of the
Proprietary Information.

24.2 ROUTE CONSTITUTES PROPRIETARY INFORMATION. The routing of the NEON Network
and the conditions of Grantee's contracts with customers and customer names are
deemed Proprietary Information without further notice and will not be disclosed
by Grantor absent an order by a court or regulatory body with jurisdiction over
Grantor.

                                       26
<PAGE>

default notice under Section 34. The Grantor shall pay, when they become due,

tax liability incurred by Grantor as a result of its acquisition of NUNet.
Grantee will supply Grantor on request and no more frequently than quarterly
with the costs and other details of any additions to NUNet such that each
separate Grantor operating company can calculate its individual income tax
liability. Grantor shall take reasonable efforts suggested by Grantee to
minimize the amount of said income tax liability on its return(s), in accordance
with applicable laws and regulations. The parties agree that Grantor's tax
liability to be reimbursed hereunder and under the 2002 Phase 2 Agreement
through June 25, 2002 is in the amount of $1,425,439. This amount shall be
deemed to be billed in full on July 1, 2004 and be due and payable by Grantee no
later than December 31, 2004. Grantor shall, from time to time, calculate any
additional income tax liability for NUNet acquired after June 25, 2002 and
invoice Grantee. Grantee shall pay such amount within sixty (60) days of
receiving such invoice. Grantee shall hold harmless, indemnify and defend
Grantor in the event Grantor's tax position with respect to NUNet is 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 of the time value of money and the
timing of any actual tax payments) equivalent to Grantor's tax liability
described in this paragraph. In a given year, Grantee shall only be obligated to
provide reimbursement valued up to an amount equal to the tax liability incurred
by Grantor for the prior tax year, plus any unused reimbursement amounts from
earlier years.

33. INDEMNIFICATION

employees, contractors, subcontractors, agents, directors, officers, affiliates,
and subsidiaries and their respective employees, subcontractors, agents,
directors and officers from and against any and all liabilities, damages,
losses, claims, demands, judgments, costs, and expenses (including, subject to

Grantee's use of the Cable including, without limitation, any claim for
infringement of patent or trade secret, made by Third Parties (collectively,
"Claims").

                                       27
<PAGE>

33.2 INDEMNIFICATION PROCEDURES. The Grantor shall give prompt notice of any
Claim for which indemnification is or will be sought under this Section and
shall cooperate and assist the Grantee in the defense of the Claim. The Grantee
shall bear the cost of and have the right to control the defense and shall have
the right to select counsel after consulting with the Grantor. The obligation to
indemnify shall be net of any tax or insurance benefit obtained by the Grantor.

33.3 LIMITATION OF GRANTOR LIABILITY. In no event shall Grantor be liable to the
Grantee or to its customers, whether in contract, tort, or otherwise, including
strict liability, for any special, indirect, incidental or consequential damages
or any lost business damages in the nature of lost revenues or profits, and any
such claims by Third Parties against Grantor shall invoke the obligations under,
but subject to the provisions of, Section 33.1 above.

34. DEFAULT

If either party shall allow any payment due hereunder to be in arrears more than
60 days after notice from the other party, shall allow any policy of insurance
provided by Section 19 hereof to expire without renewal, or shall remain in
default under any other provision of this Agreement other than those referred to
in Section 21 for a period of 30 days after notice by the other party of such
default, the party so notifying the other party may, at its option, terminate
this Agreement pursuant to Section 21, or avail itself of any other remedy at
law or equity, including without limitation, the remedy of specific performance,
provided, however, that, in the case of a default for other than failure of
payment or failure to maintain insurance, where the party in default proceeds
with all due diligence to cure such default and cure is not possible within said
30 days, then the party then in default shall have such time to cure the default
as the other party agrees is reasonably necessary. The parties agree that
Grantee's remedies at law for a breach by Grantor of the warranty set forth in
Section 4.7 may be inadequate and that, for such a breach where Grantee's
remedies at law are inadequate, Grantee shall be entitled to equitable relief.

35. ASSIGNMENT

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 Grantor provided that such assignment shall not limit or otherwise affect

laws, regulations or ordinances as may now or in the future be applicable to the
Grantee's use and operation of the Cable. If Grantee or any permitted assignee
shall at any time fail to maintain such approvals, Grantor may terminate this
Agreement without any liability or obligation to Grantee pursuant to Section
21.3(iv).

36.2 OPINION. Within 90 days of the date of this Agreement, the Grantee shall
provide the Grantor with an opinion of counsel, in form and substance

Agreement.

36.3 GRANTOR'S OBLIGATIONS. During the term of this Agreement, the Grantor
shall, at its Actual Cost to be paid by the Grantee, obtain all approvals and

38. DISPUTE RESOLUTION

38.1 ARBITRATION. If any question shall arise in regard to the interpretation of
any provision of this Agreement or as to the rights or obligations of the
parties hereunder, the question shall be referred to the respective Program
Managers who shall deliberate such questions for not more than 15 days. If a
resolution is not forthcoming within said period the matter will be referred to
a senior executive designated by each party who shall, within 30 days of the
request of the party invoking these dispute resolution procedures, meet with
each other to negotiate and attempt to resolve such question in good faith. Such
senior executives may, if they so desire, consult outside experts for assistance
in arriving at such a resolution. In the event that the resolution is not
achieved within 30 days after such a request, then the question shall be finally
resolved by the award of arbitrators (all of whom shall be arbitrators certified
by the American Arbitration Association) named as follows:

              (i) the party sharing one side of the dispute shall name an
arbitrator and give written notice thereof to the party sharing the other side
of the dispute;

              (ii) the party sharing the other side of the dispute shall, within
14 days of receipt of such written notice, name an arbitrator; and

              (iii) the arbitrator so named shall within 15 days after the
naming the latter of them, select an additional arbitrator. If such additional
arbitrator is not selected within fifteen (15) days of the appointment of the
latter of the arbitrators the party sharing either side of the dispute may seek
to appoint such third arbitrator by applying to the American Arbitration
Association. The arbitrators shall proceed promptly to hear and determine the
matter in controversy. The arbitration shall be conducted in accordance with the
Commercial Arbitration Rules of the American Arbitration Association. The
arbitrators shall be instructed that their decision must be made within 45 days
after the appointment of the third arbitrator, subject to any reasonable delay
due to unforeseen circumstances.

                                       31
<PAGE>

38.2 AWARD, COSTS. The decision of the arbitrators shall be in writing and
signed by the arbitrators or a majority of them and shall be final and binding
on the parties, and the parties shall abide by the decision and perform the
terms and conditions thereof. Unless otherwise determined by the arbitrators,
the fees and expenses of the arbitration shall be borne by the party losing in
these dispute resolution procedures, or if no party prevails in full, as
allocated by the arbitrators based on the relative merits of the parties
positions. Judgment upon the award rendered may be in any court having
jurisdiction or application may be made to such court for a judicial acceptance
of the award and an order of enforcement, as the case may be. All arbitration
shall be conducted in Worcester, Massachusetts.

39. EXERCISE OF RIGHTS

39.1 NO WAIVER. No failure or delay on the part of either party hereto in
exercising any right, power or privilege hereunder and no course of dealing
between the parties shall operate as a waiver thereof, nor shall any single or
partial exercise of any right, power or privilege hereunder preclude any other
or further exercise thereof or the exercise of any other right, power or
privilege.

39.2 GRANTEE'S SELF HELP RIGHTS. In the event the Grantor shall default or in
any manner fail to perform any of its maintenance obligations hereunder and such
failure shall continue for twenty (20) days after written notice from the
Grantee, then, unless such failure is the result of a Force Majeure Event, the
Grantee shall have the right, but not the obligation, so long as such failure
continues, to perform such obligations of the Grantor in accordance with the
relevant provisions of this Agreement, provided that Grantee shall only use
properly qualified and licensed personnel to perform such maintenance, shall
proceed in accordance with all applicable laws, codes and regulations, and shall
provide advance written notice prior to entering Grantor's property.

40. ADDITIONAL ACTIONS AND DOCUMENTS

40.1 FURTHER ACTIONS. Each of the parties hereto hereby agrees to take or cause
to be taken such further actions, to execute, acknowledge, deliver and file or

purposes, terms and conditions of this Agreement, whether at or after the
