         (a) Material breach of any warranty or representation by the defaulting

         (b) Material failure to perform the defaulting party's obligations
hereunder and a failure to cure substantially such breach if monetary within
fifteen (15) days and if monetary within thirty (30) days of written notice
describing the breach, including with respect to I(3)S its failure to (i)
maintain the service standards set forth in Sections 7.1 and 7.2 and Exhibits D
and E hereof, and (ii) make the payments to Forest City set forth in Section
8.1 hereof.

         (c) The defaulting party's ceasing to conduct business in the normal
course, insolvency, the making of a general assignment for the benefit of its

<PAGE>   12

default set forth hereunder within the applicable time period, except for
defaults pursuant to Section 12.1(c) which shall have a cure period of ninety
(90) days, after written notice of such default by the non-defaulting party
specifying the acts or omissions constituting the default with reference to the
sections of this Agreement which have allegedly been breached, the
non-defaulting party may terminate this Agreement without further obligation on
the part of the non-defaulting party, and pursue any claims at law or in equity
against the defaulting party.

         12.3 FAILURE TO EXERCISE REMEDY. The remedies set forth above are
cumulative, but the non-defaulting party is under no obligation to exercise any
such remedy. The exercise of, or failure to exercise, any such remedies shall
not prevent any future exercise of the same or any other remedies or release the
defaulting party from its obligations under this Agreement.

         12.4 EFFECT OF TERMINATION. Termination of this Agreement shall not
impair either party's then accrued rights, obligations, liabilities or remedies

smooth transition to any new provider of Internet access service, including but
not limited to providing a continuation of the Service with Forest City's
consent past the expiration or earlier termination of this Agreement on a
month-to-month terminable at will basis for a time period not to exceed three
(3) months. Any holding over by I(3)S without the consent of Forest City shall
be construed to be a tenancy from month-to-month and 1(3)S agrees it shall pay
two (2) times the Section 8.1 Revenue allocation obligations due thereunder and
continue to comply and remain in accordance with all of the other terms,
provisions, covenants and conditions contained in this Agreement, and Forest

         14.1 ENTIRE AGREEMENT. This Agreement, together with the Exhibits
attached hereto or referred to herein, constitutes the entire Agreement and
understanding among the parties hereto with respect to the provision of the
Service at the Property and is the final expression of their Agreement on that
subject and no evidence of oral or other written promises shall be binding. All
other prior agreements or understandings related to the subject hereof among the
parties, whether written or oral, shall be null and void and of no further force
and effect upon the execution of this Agreement. This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

         14.2 INCORPORATION BY REFERENCE. The Exhibits referred to herein or
attached hereto are hereby incorporated in and to this Agreement and made a part
hereof by this reference.

         14.3 AMENDMENT; MODIFICATION. This Agreement may not be supplemented,
amended, modified or otherwise altered except by written instrument executed by
all the parties hereto and


<PAGE>   14
no course of dealing or trade usage among or between the parties shall be
effective to supplement, amend, modify or alter this Agreement.

         14.4 WAIVER. The failure to enforce or to require the performance at
any time of any of the provisions of this Agreement herein shall in no way be
construed to be a waiver of such provisions, and shall not affect either the
validity of this Agreement, any part hereof or the right of any party thereafter
to enforce each and every provision in accordance with the terms of this
Agreement.

         14.5 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE IN WHICH THE PROPERTY IS LOCATED,
WITHOUT REGARD TO ITS CONFLICTS OR CHOICE OF LAWS.

         14.6 CONTINUITY OF CONTRACT. If any severable provision of this
Agreement is deemed invalid or unenforceable by any judgment of a court of
competent jurisdiction, the remainder of this Agreement shall not be affected by
such judgment, and this Agreement shall be carried out as nearly as possible
according to its original terms and intent, unless to do so would substantially
impair the underlying purposes of this Agreement. Notwithstanding the foregoing,
should the revenue allocation set forth in Section 8.1 be deemed invalid or
unenforceable for any reason by any applicable governing authority, Forest City

         14.7 CAPTIONS. The captions appearing in this Agreement are included
solely for convenience of reference and shall not be construed or interpreted to

God, or acts or government.

         14.9 HIRING PROHIBITED. During the term of this Agreement and for a
period of one (1) year thereafter, neither party shall solicit for hire or hire

This prohibition may be enforced by either party in equity and irreparable
injury shall be deemed automatically established in any such proceeding.

         14.10 PERFORMANCE REVIEW. In the event of any dispute or controversy
between the parties of any kind or nature, except in circumstances where
equitable relief is deemed necessary by either party in its sole discretion,
upon the written request of either party, each of the parties will appoint a
designated officer whose task it will be to meet for the purpose of resolving
such


<PAGE>   15
dispute or controversy or to negotiate for an adjustment to any provision of
this Agreement needed to resolve such dispute or controversy. Such officers will
discuss the dispute or controversy and negotiate in good faith in an effort to
resolve the dispute or controversy or renegotiate the applicable section or
provision of this Agreement without the necessity of any formal proceeding
relating thereto. No formal proceedings for the judicial or arbitrational
resolution of such dispute or controversy may he commenced until either or both
of the designated officers conclude in good faith that an amicable resolution
through continued negotiation of the matter at issue is not likely to occur.

contrary in this Agreement, under no circumstances will either party be deemed
to be in any relationship with the other party carrying with it fiduciary or
trust responsibilities. The parties do not intend for this Agreement or the

venture or partnership between the parties for any purpose. I(3)S has the sole

performed the day-to-day work to be performed by I(3)S under this Agreement
unless otherwise expressly provided herein or agreed to by the parties in
writing. I(3)S shall be responsible for insuring that any independent
contractors or subcontractors fully comply with all of the applicable terms of
this Agreement to the same extent that I(3)S must fully comply if it were
performing the acts performed by such contractors or subcontractors and I(3)S
shall be liable to Forest City if such contractors or subcontractors fail fully
to comply. I(3)S shall insure that no contractors or subcontractors file a
mechanic's or similar lien against the Property, the Licensed Premises and the
Forest City Equipment and I(3)S shall promptly remove all such liens that may be
filed against same. I(3)S shall insure that such contractors and subcontractors
carry insurance similar to that required of I(3)S under this Agreement prior to
the performance of any work at the Property. I(3)S shall indemnify Forest City
for actions or omissions of such contractors and subcontractors to the same
extent that I(3)S would indemnify Forest City if I(3)S engaged in the same
actions or made the same omissions.

         14.12 COUNTERPARTS. This Agreement may be signed in counterparts with
the same effect as if the signature on each counterpart were upon the same
instrument.

         14.13 MEMORANDUM OF AGREEMENT. I(3)S may record a memorandum of this
Agreement in the form set forth in Exhibit C-1 attached hereto, provided however
that this Agreement is subordinate to any and all leases, mortgages, deeds or
trusts that encumber the Property now or at any time and provided further that
I(3)S shall provide such certificates or other statements as Forest City may
request in writing to acknowledge the subordination of this Agreement.
Simultaneous with the execution of this Agreement, I(3)S agrees to execute and
deliver to Forest City a Memorandum of Termination of Agreement in the form set
forth in Exhibit C-2 attached hereto which Owner shall have the right to record
in the local property records in which the Memorandum of Agreement was recorded

<PAGE>   16


         14.14 SUBORDINATION. This Agreement is subject and subordinate to all
leases, mortgages, and/or deeds of trust which may now or hereafter affect the
Property, and to all renewals, modifications, consolidations, replacements and
extensions thereof. This clause shall be self operative and no further
instrument or subordination shall be required by any mortgage, trustee, lessor
or lessee. In confirmation of such subordination, I(3)S shall execute promptly
any certificate that Forest City may request. Notwithstanding the foregoing, the
party secured by any deed of trust shall have the right to recognize this
Agreement. In the event of any foreclosure sale under such deed of trust, this
Agreement shall continue in full force and effect at the option of the party
secured by such deed of trust or the purchaser under any such foreclosure sale.
I(3)S covenants that it will, at the written request of the party secured by any
such deed of trust, execute, acknowledge and deliver any instrument that has for
its purpose and effect the subordination to said deed of trust of the lien of
this Agreement.

         14.15 ASSIGNMENT. This Agreement shall benefit and be binding on the
respective permitted assigns, transferees and successors of the parties. Upon
thirty (30) days prior written notice to Forest City, I(3)S may assign its
rights and delegate its duties under this Agreement to any affiliate or to any
party controlled by, controlling or under common control with I(3)S or to a
party acquiring all or substantially all of I(3)S's assets; provided however,
that the assignee party must unconditionally assume in writing, and agree to be
bound by, the right, duties and obligations of I(3)S under this Agreement. Any
other assignment of this Agreement by I(3)S requires the prior written approval
of Forest City which consent will not be unreasonably withheld, conditioned or
delayed provided the assignee party must be financially qualified, be an
experienced high speed Internet access provider, and unconditionally assume in
writing, and agree to be bound by, the right, duties and obligations of I(3)S
under this Agreement. Forest City will notify any new owners of the Property
about this Agreement and has the right but not the obligation to assign this
Agreement to such new owners. Should such new owners refuse an assignment of
this Agreement, Forest City shall notify I3S that it will be terminating this
Agreement ("Termination Notice"). This Agreement shall terminate upon payment by
Forest City of a lump sum termination fee ("Termination Fee") determined
according to the following formula:

The Net Present Value (NPV) using a Discount Rate of Eight Percent (8%) of

(1) The monthly average Commissionable Revenues for the three months prior
    to the Termination Notice, net of Revenue Share Fees Due to Forest City

 X  The number of months remaining in the Term

 =  TERMINATION FEE

         INTRODUCTION

         This Exhibit entitled "Service Level Standards" ("SLS") sets out
         operation specifications and requirements for HSDS provided by I(3)S
         for the residents or customers of applicable Forest City Residential
         Management, Inc. The SLS shall encompass data services originating and
         terminating within the I(3)S internetwork ("i3s.net").

         The HSDS provided by I(3)S shall meet the operations specification and
         requirements stated herein, which are generally stated in terms of
         events or outcomes, rather than terms of specific hardware, software or
         procedural requirements. For the purposes of the SLS, i3s.net shall
         relate to that portion of the global Internet operated by I(3)S,
         originating within end users' customer premises and terminating within
         I(3)S computers or transported and peered at a public or private
         Internet Exchange Point.

         For the purposes of the SLS, a "Trouble" or "Trouble Report" shall
         relate to i3s.net or I(3)S provided services (or resold services) and
         the Equipment and I(3)S maintained facilities, but shall exclude
         customer error, defects in Customer Premises Equipment ("CPE"), defects
         in customers, computers, defects in property cable or wiring plants,
         defects in fiber optic distribution systems, defects in cable
         television distribution systems and network problems experienced by
         destination networks at or beyond Internet Exchange Points.

         The terms and conditions of this SLS do not limit I(3)S's obligations
         set forth elsewhere in the Agreement, but if there is a conflict with
         respect to service obligations between this SLS and the Agreement, this
         SLS shall control.
