cooperate with Grantee to provide additional documentation that would reasonably
allow Grantee to evaluate the acceptability of its IRU Fibers.  In addition,
Grantee shall be allowed, subject to the protocols of the Rights-of-Way
agreements, to conduct its own tests, at Grantee's expense, to determine
acceptability of its IRU Fibers.  Issuance of an Acceptance Notice or failure to
issue a notice of defective work during the time period indicated above shall
constitute "Acceptance" of the IRU Fibers by Grantee, but such Acceptance shall
not invalidate the warranty described in this Agreement.  Grantor shall take all
reasonably required action, including retesting the Grantee IRU Fibers, until
all Grantee IRU Fibers conform to the specifications in Exhibit B.

10.1 IRU Fibers may be physically spliced into the Grantor's Cable at any
technically feasible point as mutually agreed by the parties.  Splicing requires
penetration of the Cable sheath, exposing the Fibers within the sheath.  In
order to maintain the integrity of Grantor's Cable after Joint Acceptance,
Grantor, or a contractor operating under Grantor's direction, must perform all
splicing performed on Grantor's Cable.

10.2 For future expansion at existing splice points, Grantor will perform the
necessary splicing upon written or email request by Grantee.  Normal requests
for splicing shall be submitted at least thirty (30) days prior to the requested
splicing date, and expedited requests shall be submitted at least 72 hours prior
to the requested splicing date.  Grantor shall obtain any and all permits
necessary for such splicing.  Grantee agrees that it will not perform any
splicing or interfere in any manner with Grantor's Cable.  After Acceptance, the
cost of splicing Fibers into Grantor's Cable will be borne by Grantee.  The
Optical Splice Points for each route shall be mutually agreed upon in writing by
the parties.  Grantor shall provide Grantee with a splicing and splice testing
schedule(s) so Grantee's representative may be present, subject to protocols of
Rights-of-Way agreements.  Splicing documentation (ATP and test results) will be

the construction of Grantee's IRU Fibers covered by this Agreement will be new,
of good quality, properly constructed and/or installed, free of defects, and in
conformity with the requirements of this Agreement.  Such warranty shall be
effective, with respect to each specific Segment, for the same period of
Warranty provided to Grantor by its contractors (normally a one (1) year period
from date of acceptance by Grantor).  All work not conforming to the standards
may be considered defective by Grantee and Grantor shall immediately replace any
damaged or defective work at its own expense.  Grantor shall use reasonable
efforts to promptly repair or replace all such defective work; provided that
Grantor shall repair or replace such defective work within thirty (30) days
following its confirmation of the defect, unless reasonable circumstances
dictate a shorter or longer period, in which event the parties shall in good
faith mutually agree upon such period.  All replaced defective equipment or
items shall become the sole property of Grantor.

11.2 Grantee's sole and exclusive remedy and Grantor's sole and exclusive
maximum liability under the warranties contained in this Article shall be, at
the sole option of Grantor, to repair (with new or functionally operative parts)
or replace any defective portion of its Cable of which Grantor receives notice
during the warranty period, provided that Grantor is promptly notified in
writing upon discovery by Grantee that any portion of Grantee's IRU Fibers has
failed to conform with the terms of this Agreement, such writing to include an
explanation of alleged defects.

11.3 In addition to the foregoing warranties, Grantor hereby assigns to Grantee,
and Grantee shall have the benefit of, any and all contractors' and suppliers'
warranties with respect to the material in the Cable.

11.4 Grantor's warranties do not extend to defects caused by acts of God,
accident, fire or other hazard, nor resulting from Grantee's, its designees or
third parties misuse, neglect, alterations, storage, attempts to repair, or use
of other supplies not meeting specifications.

THE FOREGOING WARRANTIES AND REMEDIES CONSTITUTE THE ONLY WARRANTIES WITH
RESPECT TO THE GRANTOR CABLE AND ARE EXCLUSIVE REMEDIES IN THE EVENT OF BREACH
OF SUCH WARRANTIES. SUCH WARRANTIES ARE IN LIEU OF ALL OTHER WARRANTIES, WRITTEN
OR ORAL, STATUTORY, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION, ANY
WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. NEITHER PARTY
SHALL IN ANY EVENT BE LIABLE FOR ANY INCIDENTAL, SPECIAL, OR CONSEQUENTIAL
DAMAGES OF ANY NATURE WHATSOEVER FOR ANY REASON.

                                     -----

12.1 As used in this Article XII, "Tax" or "Taxes" shall mean any and all taxes,
assessments, charges, levies, (hereinafter collectively referred to as "Taxes")
imposed by any authority having the power to tax, including any city, county,
state, or federal government or quasi-governmental agency or taxing authority.

12.2 Upon Grantee's Acceptance of its IRU Fibers, it shall only be responsible
for any and all sales, use, income, gross receipts or other Tax assessed on the
basis of revenues received by Grantee pursuant to its use of its IRU Fibers. The
parties shall cooperate to minimize adverse tax consequences and may mutually
amend this Agreement to improve their respective company's tax positions.

                                 ARTICLE XIII
                                   LIABILITY
                                   ---------

13.1 Neither Grantor nor Grantee shall be liable to the other for any indirect,
special, punitive or consequential damages (including, but not limited to, any
claim from any customer for loss of services) arising under this Agreement or
from any breach or partial breach of the provisions of this Agreement or arising
out of any act or omission of either party hereto, its directors, officers,
employees, servants, contractors and/or agents.  Both Grantor and Grantee shall
include in any agreement with any third party relating to the use of the Grantor
Cable or Grantee's IRU Fibers a waiver by such third party of any claim for
indirect, special, punitive or consequential damages (including, but not limited
to, any claim from any client or customer for loss of services) arising out of
or as a result of any act or omission by either party hereto, its directors,
officers, employees, servants, contractors and/or agents.

13.2 Subject to the limitation on indirect, special, punitive or consequential
damages in Article 13.1, each party assumes, releases and agrees to indemnify,
defend, protect and save the other (including its directors, officers, agents,
representatives and employees) harmless from and against any claim, damage,
loss, liability, injury, cost and expense (including reasonable attorney's fees
and expenses) in connection with any loss or damage to any property or
facilities of the indemnified party arising out of or resulting in any way from
the acts or omissions to act, negligence or willful misconduct of the
indemnifying party, its directors, officers, employees, servants, contractors
and/or agents in connection with the exercise of its rights and obligations
under the terms of this Agreement.  The parties hereto expressly recognize and
agree that each parties' 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, under the terms of this Agreement.  In the
event a party shall fail for any reason to indemnify, defend, protect and save
the other harmless, the indemnified party hereby expressly recognizes that its
sole remedy in such event shall be the right to bring suit against the
indemnifying party for its damages as a result of the indemnifying party's
failure to so indemnify, defend, protect and save harmless.

13.3 Nothing contained herein 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

                                       8

any acts or omissions of such third party as such acts or omissions may affect
the construction, operation or use of the Grantor Cable or any IRU Fibers;
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 injured party to pursue any such action against such third party.

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

The obligations of the parties hereto are subject to force majeure and neither
party shall be in default under this Agreement if any failure or delay in
performance is caused by strike or other labor dispute; accidents; acts of God;
fire; flood; earthquake; lightning; unusually severe weather; material or
facility shortages or unavailability not resulting from such party's failure to
timely place orders therefor; lack of transportation; legal inability to access
property; acts of any governmental authority; government codes, ordinances,
laws, rules and regulations or restrictions (collectively "Regulations") (but
not to the extent the delay caused by such Regulations could be avoided by
rerouting the Cable if such a reroute was commercially reasonable); condemnation
or the exercise of rights of eminent domain; war or civil disorder; or any other
cause beyond the reasonable control of either party hereto.  The  excused party
shall use reasonable efforts under the circumstances to avoid or remove such
causes of non-performance and shall proceed to perform with reasonable dispatch
whenever such causes are removed or ceased.  Notification to be given by the
excused party of the cause and of the estimated duration, when possible.

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

15.1 Grantor shall obtain on or before Acceptance with respect to each Segment
to be delivered hereunder, any and all right-of-way agreements, easements,
licenses, rights, or other agreement necessary for the use of poles, conduit,
cable, wire, physical plant facilities, and/or access to real property
underlying the Grantor's Cable ("Rights-of-Way").  Further, as of Acceptance,
Grantor shall obtain any and all rights, licenses, franchises, authorizations,
agreements, permits, and approvals (including without limitation, any necessary
local, state, federal or tribal authorizations and environmental permits) and
collectively referred to as "Permits," that are necessary for the installation
and operation of Grantor's Cable.  Grantor shall obtain all Rights-of-Way and
Permits in the name of Grantor.  In addition, Grantor shall use its reasonable
best efforts to obtain Rights-of-Way which will allow Grantee access to its IRU
Fibers in the presence of Grantor's employee or agent.  Both parties shall
cooperate to obtain such Rights-of-Way.

15.2 It is expressly understood that Grantor's and Grantee's obligations under
this Agreement are conditioned upon and shall in all respects be subject to the
continuation or acquisition of such Rights-of-Way and Permits.  The parties
shall use their best efforts to obtain or to cause such Rights-of-Way and
Permits to remain effective through the Term of this Agreement, and any
extension thereof.  Copies of any and all agreements with respect to the Rights-
of-Way and Permits shall be made available to the other party upon request.  If
confidentiality obligations

                              RELOCATION OF CABLE
                              -------------------

16.1 If Grantor is required to relocate or replace its Cable or any of the
appurtenant facilities used or required in providing the IRU, and the gross cost
(excluding reimbursements) of Grantor's relocation or replacement exceeds $5,000
per occurrence, then, so long as such work is not necessitated by a breach of
Grantor's obligations, Grantee shall reimburse Grantor for Grantee's
Proportionate Share of such costs, including, without limitation, fiber
acquisition, splicing, and testing.  In the event that a third party reimburses
Grantor for all or a portion of the cost to perform such work, then this
reimbursement amount shall reduce on a dollar for dollar basis the aggregate
amount of costs deemed to have been spent by Grantor.  Grantor shall deliver to
Grantee updated as-built drawings and Documentation with respect to any
relocated portion of the Cable not later than one hundred eighty (180) days
following such relocation.

16.2 Grantor shall give Grantee sixty (60) days prior notice of any such
relocation, if possible, and shall have the obligation to proceed with such
relocation, including, but not limited to, the right to determine the extent of,
the timing of, and methods to use for such relocation; provided that any such
relocated Cable and Fibers shall be constructed and tested in accordance with
the specifications and requirements set forth in this Agreement. Acceptance of
the relocated IRU Fibers shall be in accordance with Article V of this
Agreement.  In addition, Grantor shall use reasonable efforts to ensure
relocation shall not result in an adverse change to the operations, performance,
or connection points with the network of Grantee, or end points of the
applicable Cable.

16.3 Grantee has the right to review and approve the relocation plans of Grantor
fourteen (14) days prior to any relocation and has the right to have, subject to
the protocols of the Rights-of-Way Agreements, a representative present at the
time Grantor relocates the Cable that contains Grantee's IRU Fibers.

                                   INSURANCE
                                   ---------

17.1 Grantee and Grantor shall, itself or through its contractors, each maintain
insurance, for the duration of this Agreement, as follows:

          limits: Personal Injury - $5,000,000 each person and $5,000,000 each
          accident, and Property Damage - $1,000,000 each accident.

     (c)  Railroad Protective Liability Coverage required for any work within
          fifty (50) feet of a railroad right-of-way: $2,000,000 or any other
          amounts required by the Rights-of-Way providers.  However this
          requirement upon Grantee may be waived if both Grantor and Grantee
          determine that it is not necessary.

     (d)  Automobile Liability Insurance for owned, hired and non-owned autos:
          $2,000,000 combined single limit bodily injury/property damage.

Insurance amounts contained in this section shall be increased by the respective
parties every ten (10) years based upon the increase in the Consumer's Price
Index.

17.2 Failure of either party to enforce the minimum insurance requirements
listed above shall not relieve the other party of the responsibility for
maintaining these coverages.  The parties shall furnish to each other
certificates of insurance reflecting policies carried and limits of coverage as
required above, which shall state that thirty (30) days notice shall be given
prior to cancellation, non-renewal or any material change in any such insurance
coverage.  The insurance for both parties shall name the other as an additional
insured.

17.3 Contractor(s) employed by the parties to work on the Fiber Optic Cable
shall provide and maintain at all times during the provision of services to the
parties the same types of and amounts of insurance (with the exception of the
amount of Comprehensive General Liability Insurance), which insurance shall be
issued by companies approved by the parties.

For Comprehensive General Liability Insurance, contractor(s) shall carry:

          (1) Combined Single Limit: $2,000,000 each occurrence; and

          (2)  Bodily Injury and Property Damage: $2,000,000 general aggregate,

<PAGE>

The contractor(s) insurance shall be evidenced by certificates of insurance
which shall be delivered to the contracting party prior to commencement of the
provision of services.  The certificates of insurance shall show that the
insurance is prepaid and in full force and effect and that such insurance shall
not be canceled, non-renewed or changed during the term of this Agreement or
during any extension thereof, without at least thirty (30) days written notice
to Grantor and Grantee.  The maintenance of insurance by the contractor shall in
no way limit or affect the extent of the contractor's liability.

                                 ARTICLE XVIII
                                 CONDEMNATION
                                 ------------

18.1 In the event any portion of the Grantor Cable, or the Rights-of-Way in or
upon which it has been installed, becomes 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 Grantee's interest (being its Proportionate Share) shall be severed from
Grantor's interest in such proceeding.  Grantee shall be entitled to
independently pursue an award for its interest in such proceedings and the
parties hereto agree to have any such condemnation awards specifically allocated
between Grantor's interest and Grantee's interest.  In the event Grantee's
interest in such proceeding cannot be severed from Grantor's interest, Grantee
shall be entitled to receive its Proportionate Share of the award for its
interest in Grantee's IRU Fibers and occupancy of the Rights-of-Way.

18.2 Upon its receipt of a formal notice of condemnation or taking, Grantor
shall notify Grantee immediately of any condemnation proceeding filed against
Grantor's Cable, including Grantee's IRU Fibers, or the Rights-of-Way in or upon
which Grantee's IRU Fibers have been installed.  Grantor shall also notify
Grantee of any similar threatened condemnation proceeding and agrees not to sell
the Cable or release Rights-of-Way to such acquiring agency, authority or other
party in lieu of condemnation without the prior written consent of Grantee,
which consent shall not be unreasonably conditioned, delayed or denied.

18.3 It is expressly recognized and understood by Grantee that relocation costs
resulting from any such condemnation proceeding may not be reimbursed by the
condemning authority and, if Grantee requests Grantor to relocate Grantee's IRU
Fibers, Grantee shall pay  its Proportionate Share of all costs associated with
the relocation of Grantee's IRU Fibers in excess of such costs which were
reimbursed by the condemning authority.  If Grantee's IRU Fibers are relocated
by Grantor pursuant to this Article 18.3, Grantee shall pay to Grantor all
condemnation awards given to Grantee, if any, that relate to the relocation of
that portion of Grantee's IRU Fibers.

                                  ARTICLE XIX
                                CONFIDENTIALITY
                                ---------------

19.1 Grantee and Grantor represent, certify, and warrant that they shall use
their best reasonable efforts to ensure that any and all information and
documents obtained from the other party during the term of this Agreement,
and identified as being confidential information will be held in strict
confidence and will not be used by their company, its employees, subcontractors,
consultants or agents for any purpose other than its performance required by
this Agreement.

19.2 All documents, data, or information furnished by Grantee or Grantor is the
sole property of that party. Upon the expiration of this Agreement and any
extensions thereof, those documents, data, or information shall be returned to
its owner if readily available.

19.3 Neither Grantee nor Grantor may make any news release, public announcement,
denial or confirmation concerning all or any part of this Agreement or use the
other's name in sales or advertising materials, or in any manner advertise or
publish the fact that the companies have entered into this Agreement, or
disclose any of the details of this Agreement to any third party, including the
press, without the prior written consent of the other party, except such
disclosures required by law, or the rules and regulations of the relevant
government agencies.

                                  ABANDONMENT
                                  -----------

Should Grantee decide to abandon all or part of its IRU Fibers, it may do so by
informing Grantor in writing, such abandonment being made at no cost to either
party.  Grantee shall remove its equipment and electronics within thirty (30)
days of such notification of abandonment by Grantee, failing which Grantor shall
remove same at Grantee's cost payable within thirty (30) days of receipt of the
invoice.  At the time of abandonment, Grantee shall have no further rights with
respect to its IRU.  Such abandonment shall not reduce or otherwise affect
Grantee's obligations hereunder.

                                  ARTICLE XXI
                                    DEFAULT
                                    -------

21.1 Neither party shall be in default under this Agreement unless and until the
other party shall have given the defaulting party written notice of such default
and the defaulting party shall have failed to cure the default within thirty
(30) days after written receipt of such notice; provided, however, that where a
default cannot be reasonably cured within the thirty (30) day period, if the
defaulting party shall promptly proceed to cure the default with due diligence,
the time for curing the default shall be extended for a period of up to ninety
(90) days from the date of receipt of the default notice.

21.2 Upon the failure by the defaulting company to timely cure any default after
notice thereof from the non-defaulting party, the non-defaulting party may take
any action it determines, in its discretion, to be necessary to correct the
default, and/or pursue any legal remedies it may have under applicable law or
principles of equity relating to the breach.

21.3 The parties acknowledge and agree that irreparable damage would occur in
the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached.  It is
accordingly agreed that each party shall be entitled to injunctive or similar
preliminary relief to prevent or cure breaches of the provisions of this

                                       13
<PAGE>

Agreement by the other and to enforce specifically the terms and provisions
hereof, this being in addition to any other remedy to which they may be entitled
by law or equity.

21.4 An event of default shall also be deemed to have occurred if a party
becomes insolvent, or institutes or has instituted against it bankruptcy
proceedings which are not dismissed within ninety (90) days of filing, or makes
a general assignment for the benefit of creditors, or if a receiver is appointed
for the benefit of its creditors, or if a receiver is appointed on account of
its insolvency, and the non-defaulting party may immediately terminate this
Agreement.

23.1 Except as provided in this Article, Grantee shall not assign this Agreement
to any other party without the prior written consent of Grantor, which shall not
be unreasonably withheld, provided, however, that without such consent, Grantee
shall have the right to assign, sublet or otherwise transfer this Agreement, in
whole or in part, to any parent, subsidiary or affiliate of Grantee or to any
person, firm or corporation which shall control, be under the control of or be
under common control with Grantee, or any corporation or entity into which
Grantee or a subsidiary of Grantee may be merged or consolidated or which
purchases all or substantially all of the assets of Grantee or a subsidiary of
Grantee.

23.2 Except as provided in this Article, Grantor shall not assign this Agreement
to any other party without the prior written consent of Grantee, which shall not
be unreasonably withheld, provided, however, that without such consent, Grantor
shall have the right to assign, sublet or otherwise transfer this Agreement, in
whole or in part, to any parent, subsidiary or affiliate of Grantor or to any
person, firm or corporation which shall control, be under the control of or be

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

This Agreement shall be interpreted and construed in accordance with the laws of
the state in which the Cable is located, without regard to its conflict of laws

                            INDEPENDENT CONTRACTOR
                            ----------------------

The performance by Grantee and/or Grantor of all duties and obligations under
this Agreement shall be as independent contractors and not as agents of the
other party, and no persons employed or utilized by a performing party shall be
considered the employees or agents of the other. Neither party shall have the
authority to enter into any agreement purporting to bind the other without its
specific written authorization. The parties agree that this Agreement does not
create a partnership between, or a joint venture of Grantee and Grantor.

                                 ARTICLE XXVI
                              DISPUTE RESOLUTION
                              ------------------

26.1 It is the intent of Grantor and Grantee that any disputes which may arise
between them, or between the employees of each of them, be resolved as quickly
as possible. Quick resolution may, in certain circumstances, involve immediate
decisions made by the parties' representatives. When such resolution is not
possible, and depending upon the nature of the dispute, the parties hereto agree
to resolve such disputes in accordance with the provisions of this Article.  The
obligation herein to arbitrate shall not be binding upon any party with respect
to request for preliminary injunctions, temporary restraining orders, specific
performance or other procedures in a court of competent jurisdiction to obtain
interim relief when deemed necessary by such court to preserve the status quo or
prevent irreparable injury pending resolution by arbitration of the actual
dispute.

26.2 Grantee and Grantor shall each designate, by separate letter,
representatives as points of contact and decision making with respect to the
obligations and rights of the parties, said letters to be furnished by each
party to the other within thirty (30) days from the date of this Agreement.  Any
disputed issues arising during the term of this Agreement shall in all instances
be initially referred to the parties' designated representatives. The parties'
designated representatives shall render a mutually agreeable resolution of the
disputed issue, in writing, within seventy-two (72) hours of such referral.
Either party may modify the designated representative upon written notice to the
other party.

26.3 Any claims or disputes arising under the terms and provisions of this
Agreement, or any claims or disputes which the parties' representatives are
unable to resolve within the seventy-two (72) hour time period shall continue to
be resolved between the parties' representatives if mutually agreeable, or may
be presented by the claimant in writing to the other party within thirty (30)
days after the circumstances which gave rise to the claim or dispute took place
or become known to the claimant, or within thirty (30) days after the parties'
representatives fail to achieve resolution, whichever is later.  The written
notice shall contain a concise statement of the claim or issue in dispute,
together with relevant facts and data to support the claim.

26.4 Any controversies or disputes arising out of or relating to this Agreement
shall be resolved by binding arbitration in accordance with the then current
Commercial Arbitration Rules of the American Arbitration Association. The
parties shall endeavor to select a mutually acceptable arbitrator knowledgeable
about issues relating to the subject matter of this Agreement.  In the

                                       16
<PAGE>

event the parties are unable to agree to such a selection, each party will
select an arbitrator and the arbitrators in turn shall select a third
arbitrator.

The arbitrator(s) shall not have the authority, power or right to alter, change,
amend, modify, add or subtract from any provision of this Agreement, except
pursuant to Article 29.3, or to award punitive damages. The arbitrator shall
have the power to issue mandatory orders and restraining orders in connection
with the arbitration. The award rendered by the arbitrator shall be final and
binding on the parties and judgment may be entered thereon in any court having
jurisdiction. The agreement to arbitration shall be specifically enforceable
under the prevailing arbitration law.

26.5 During the continuance of any arbitration proceeding, each party shall
continue to perform their respective obligations under this Agreement.

                                     LIENS
                                     -----

27.1 In the event Grantee's IRU Fibers become subject to any mechanics',
artisans' or materialmen's lien, or other encumbrance chargeable to or through
Grantor which interfere with the IRU Fibers or jeopardize Grantee's use of its
IRU Fibers, Grantor 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 Grantee and shall indemnify Grantee against all
costs and expenses (including 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 thirty (30) days after
written notice by Grantee to Grantor, then Grantee may pay or secure the release
or discharge thereof at the expense of Grantor.  Grantor shall reimburse Grantee
for such payments within thirty (30) days of invoice by Grantee.

27.2 Grantor agrees and acknowledges that it has no right to use any of
Grantee's IRU Fibers included in Grantor's Cable.  Grantor shall obtain from any
entity in favor of which Grantor in its discretion may grant after the date of
this Agreement a security interest or lien on all or part of Grantor's Cable, a
written nondisturbance and subordination agreement in form and substance
reasonably satisfactory to Grantee.  The nondisturbance and subordination
agreement will be written to the effect that such lienholder acknowledges
Grantee's and other present or future participants' interest and rights in
Grantee's IRU Fibers and the IRU granted by this Agreement, and agrees that the
same shall not be diminished, disturbed, impaired or interfered with in any
adverse respect by such lienholder.

27.3 Grantee agrees and acknowledges that it has no right to use any of the
fibers, other than Grantee's IRU Fibers, included in Grantor's Cable or
otherwise incorporated in Grantor's system and that Grantee shall keep any and
all of Grantor's system, other than Grantee's IRU granted in the IRU Fibers,
free from any liens, rights or claims of any third party attributable to
Grantee.  Notwithstanding the aforementioned, Grantee shall obtain from any
entity in favor of which Grantee in its discretion may grant after the date of
this Agreement a security interest or lien on all or part of such IRU granted by
this Agreement, a written nondisturbance agreement substantially to the effect
that such lienholder acknowledges Grantor's and other present or future

                                       17
<PAGE>

participants' interest and rights in Grantor's Cable and agrees that the same
shall not be diminished, disturbed, impaired or interfered with in any adverse
respect by such lienholder.

                                 MISCELLANEOUS
                                 -------------

28.1 The headings of the Articles in this Agreement are strictly for convenience
and shall not in any way be construed as amplifying or limiting any of the
terms, provisions or conditions of this Agreement.

28.2 In construction of this Agreement, words used in the singular shall include
the plural and the plural the singular, and "or" is used in the inclusive sense,
in all cases where such meanings would be appropriate.

28.3 No provision of this Agreement shall be interpreted to require any unlawful
action by either party.  If any section or clause of this Agreement is held to
be invalid or unenforceable, then the meaning of that section or clause shall be
construed so as to render it enforceable to the extent feasible.  If no feasible

restrictions set forth herein. The Shares shall vest over a two-year period
beginning on the date hereof, so long as the Executive remains in the continuous

relevant Lock-up Period and, unless otherwise agreed, the certificate will be
transferred to the Executive only after satisfaction by the Executive of all
federal, state and local income and employment tax withholding liabilities that
arise either on account of the Section 83(b) election (described below) or the
vesting of such Share.

     (b)   The Executive may elect pursuant to Section 83(b) of the Internal
Revenue Code, within 30 days of the date of grant, to include in his or her
gross income the fair market value of all or any portion of the Shares covered

the Shares except as otherwise limited by the terms of this Agreement.

     (d)  In the event of any change in the Common Stock of Acquiror by reason
of any stock dividend, stock split, split-up or any similar change affecting the
Common Stock, the number and kind of Shares awarded hereunder shall be adjusted
automatically consistent with such change.

     4.  Termination.

not disclose or use at any time, either during his employment with the
Corporation or thereafter, any Confidential Information (as defined below) of
which Executive is or becomes aware, whether or not such information is
developed by him, except to the extent that such disclosure or use is directly
related to and required by Executive's performance of duties assigned to
Executive by the Corporation or is required by law. In addition, the Executive
acknowledges that some Confidential Information will contain material, non-
public information (within the meaning of the federal securities laws) that may
remain material and non-public for an extended period of time.  You are aware
that the Federal securities laws impose restrictions on trading by persons in
possession of non-public information and agree to comply with such restrictions.
Executive shall take all appropriate steps to safeguard Confidential Information
and to protect it against disclosure, misuse, espionage, loss and theft.  As
used in this Agreement, the term "Confidential Information" means information
that is not generally known to the public and that is used, developed or
obtained by the Corporation in connection with their business, including but not
limited to (i) products or services, (ii) fees, costs and pricing structures,
(iii) designs, (iv) analysis, (v) drawings, photographs and reports, (vi)
computer software, including operating systems, applications and program

(xii) copyrightable works, (xiii) all technology and trade secrets, (xiv)
strategic plans, potential acquisitions, business plans, budgets and financial
models, and (xv) all similar and related information in whatever form.
Notwithstanding the foregoing, "Confidential Information" shall not include any
information (A) of which Executive became aware prior to his affiliation with
the Corporation, (B) of which Executive learns from sources other than the
Corporation or (C) which is disclosed in a prospectus or other documents for
dissemination to the public or published in a form generally available to the
public prior to the date Executive proposes to discloses or uses such
information.  Information shall not be deemed to have been published merely
because individual portions of the information have been separately published,
but only if all material portions thereof have been published.

     5.2  The Corporation's Ownership of Intellectual Property.
          ----------------------------------------------------

     (a)(i) Acknowledgment of Corporation Ownership.  In the event that
            ---------------------------------------
Executive as part of his activities on behalf of the Corporation generates,
creates, authors or contributes to any invention, design, new development,

practice or constituting Confidential Information), any copyrightable
<PAGE>

                                      -6-

work (whether or not constituting Confidential Information) or any other form of
Confidential Information relating directly or indirectly to the Corporation's
business as now or hereafter conducted (collectively, "Intellectual Property"),
Executive acknowledges that such Intellectual Property is the exclusive property
of the Corporation and hereby assigns all right, title and interest in and to
such Intellectual Property to the Corporation. Any copyrightable work prepared
in whole or in part by Executive will be deemed "a work made for hire" under
Section 201(b) of the 1976 Copyright Act, and the Corporation shall own all of
the rights comprised by the copyright therein. Executive shall promptly and
fully disclose all Intellectual Property to the Corporation and shall cooperate
with the Corporation to protect their interests in and rights to such
Intellectual Property (including, without limitation, providing reasonable
assistance in securing patent protection and copyright registrations and
executing all documents as reasonably requested by the Corporation, whether such
requests occur prior to or after termination of Executive's employment with the
Corporation).

     (ii) Executive Invention.  Executive understands that Section 5.2(a)(i) of
          -------------------
this Agreement regarding the ownership by the Corporation of Intellectual
Property does not apply to any invention for which no equipment, supplies,
facilities or trade secret information of the Corporation were used and which
was developed entirely on Executive's own time, unless (A) the invention relates
to the business of the Corporation to any of their actual or demonstrably
anticipated research or development or (B) the invention results from any work
performed by Executive for the Corporation.

     (b) Delivery of Materials upon Termination of Employment.  As requested by
         ----------------------------------------------------

to the Corporation all copies and embodiments, in whatever form, of all
Confidential Information and Intellectual Property in Executive's possession or
within his control (including, but not limited to, written records, notes,
photographs, manuals, notebooks, documentation, program listings, flow charts,
magnetic media, disks, diskettes, tapes and all other materials containing any

or form of such material and, if requested by the Corporation, shall provide the
Corporation with written confirmation that all such materials have been
delivered to the Corporation.

     5.3  Noncompete.   Executive acknowledges and agrees with the Corporation
          ----------
that in the course of his employment with the Corporation, he shall become
familiar with the Corporation's trade secrets and with other Confidential
Information concerning the Corporation, that Executive's services to the
Corporation are unique in nature and of an extraordinary value to the
Corporation, and that the Corporation would be irreparably damaged if Executive
were to provide similar services to any person or entity competing with the
Corporation or engaged in a similar business.  In consideration of and as an
inducement to the Corporation entering into this Agreement and granting of the
restricted Shares hereunder, Executive accordingly covenants and agrees with the
Corporation that during the Noncompete Period (as defined in Section 6.5),
Executive shall not, directly or indirectly, either for himself or for or
through any other individual, corporation, partnership, joint venture or other
entity, participate in any business or enterprise conducting or proposing to
conduct business in any Covered State (as defined below) which engages or
proposes to engage in the provision of telecommunications services or in any
<PAGE>

                                      -7-

other business competitive with any business engaged in by the Corporation
during the period of time in which Executive is employed by the Corporation.

     For purposes of this Agreement, (i) the term "participate in" shall
include, without limitation, having any direct or indirect interest in any
corporation, partnership, joint venture or other entity, whether as a sole
proprietor, owner, stockholder, partner, member, joint venturer, creditor or
otherwise, or rendering any direct or indirect service or assistance to any
individual, corporation, partnership, limited liability company, joint venture
or other business entity (whether as a director, officer, manager,

publicly traded and (ii) the term "Covered State" means Connecticut, Delaware,
