<PAGE>   6
Upgrade Deadline Date (the "First Year"), subject to section 2.4, any
capacity provided during the First Year under the Domestic IRU shall be
configured at an OC-3 level.

         2.2 Except as expressly set forth in the following sub-paragraphs, all
Capacity comprising a portion of the Globix IRU shall be delivered to Globix at
a cross-connect panel located in the Qwest POP in each designated city as set
forth in Exhibit A hereto. Unless Globix has separately arranged for co-location
space in any such Qwest facility, it shall be the responsibility of Globix to
obtain any required transiting facilities or local distribution facilities to
interconnect with the Qwest Capacity.

         2.3 Qwest hereby grants to Globix an Indefeasible Right of Use, for the
purposes described herein, in DS-3 configured Capacity on Qwest's Gemini
submarine cable system between the international city pair identified in Exhibit
A hereto, for the Term defined in Section 5.1, all on the terms and subject to
the conditions set forth herein (the "International IRU"). The Domestic IRU and
the International IRU are hereinafter referred to as the "Globix IRU."

         2.4 Qwest hereby grants Globix an option (the "Upgrade Option") to
maintain the Capacity of the Domestic IRU up to an OC-3 level after the Upgrade
Deadline Date. In the event Globix fails to exercise the Upgrade Option any and
all capacity provided under the Domestic IRU shall be reduced to a DS-3 level.
The Upgrade Option shall be exercised on or before the Upgrade Deadline Date by
delivery to Qwest of a valid written notice of exercise accompanied by the
payment (the "Increase Payment") required pursuant to section 3.5 below.

         2.5 If, at Qwest's discretion, Qwest plans to upgrade the Qwest Network

3.  CONSIDERATION FOR GRANT OF IRU

         3.1 In consideration of the grant of the Globix IRU described in
Article 2 above by Qwest to Globix, Globix agrees to pay to Qwest an IRU fee of
Nine Million One Hundred Ninety Two Thousand One Hundred Seventy Six U.S.
Dollars (US$9,192,176.00) (the "IRU Fee").

                        TABLE 3.1--COST PER DS-0 V&H MILE
<TABLE>
<S>                                                  <C>
         DS-3 to OC-48 Capacity Configuration        Cost Per DS-0 V&H Mile
                                                             US $ 1.50
         Monthly O&M Charges for 20 years                    US $.0035
</TABLE>

         3.2 Globix shall pay to Qwest ten percent (10%) of the IRU Fee upon
execution of this Agreement. From the Effective Date to the first anniversary of
the Effective Date, as Capacity is accepted by Globix, the amount due and
payable is calculated by multiplying ninety percent (90%) of the IRU Fee
("Balance") by the quantity of DS-3 V&H Miles of Capacity being accepted by
Globix and dividing by the quantity of DS-3 V&H Miles described in section 2.1
above. On the first anniversary of the Effective Date of this Agreement, any
Balance amount that has not yet been paid to Qwest is due and payable regardless
of whether Globix has accepted any or all of the Capacity subject to Qwest
making such Capacity available to Globix.

         3.3 In the event that the quantity of Qwest Capacity acquired by Globix
as set forth in Exhibit A of this Agreement is greater than the quantity of DS-3
V&H miles described in section 2.1 above, Globix shall pay to Qwest an amount
equal to US$1.50 multiplied by the number of DS-0 V&H Miles of such difference
in quantity of Capacity.

         3.4 Globix shall pay the maintenance charges set forth in Article 8.

         3.5 The Increase Payment shall be Eleven Million Three Hundred Eighty
Four Thousand Three Hundred Fifty Two U.S. Dollars (US$11,384,352.00).

4.  DELIVERY, ACCEPTANCE AND TESTING OF SEGMENTS

         4.1 Capacity will be made available to Globix by Qwest as Qwest's
schedule for building capacity permits. Capacity provided pursuant to the
International IRU may be accepted sometime between October 1, 1998 and December
31, 1998.

         4.2 At delivery the Qwest Capacity shall comply with the specifications
set forth in Exhibit B hereto (Qwest Capacity Specifications and Acceptance
Testing). Qwest shall test the Qwest Capacity in accordance with the procedures
specified in Exhibit B to verify that the Qwest Capacity is operating in
accordance with the applicable specifications described in Exhibit B. Qwest
shall provide Globix with reasonable advance notice of the date and time of each
Qwest Capacity 


                                       4
<PAGE>   8
acceptance test (each of which shall take place during normal business hours)
such that Globix shall have the right, but not the obligation, to have a person
or persons present to observe the tests.

         4.3. In the event the results of any Qwest Capacity acceptance test
show that the Qwest Capacity is not operating within the parameters of the
applicable specifications set forth in Exhibit B, Qwest shall expeditiously take
such action as shall be reasonably necessary, with respect to such portion of
the Qwest Capacity as does not operate within the parameters of the applicable
specifications, to bring the operating standards of such portion of the Qwest
Capacity within such parameters.

         4.4 If and when Qwest notifies Globix that the test results of the
Qwest Capacity acceptance test are within the parameters of the specifications
in Exhibit B with respect to the tested Qwest Capacity, Globix shall provide
Qwest with a written notice accepting such Qwest Capacity. If Globix fails to
notify Qwest of its acceptance or rejection of the final test results with
respect to the Qwest Capacity within ten (10) business days after its receipt of
notice of such test results, Globix shall be deemed to have accepted such Qwest
Capacity. The date of such notice of acceptance (or deemed acceptance) of the
Qwest Capacity shall be the "Acceptance Date" for that Qwest Capacity.

5.  TERM

         5.1 The term of this Agreement (the "Term") shall begin on the
Effective Date (provided that the grant of the IRU hereunder with respect to any
Capacity shall not become effective until the Acceptance Date for that
Capacity); and, subject to the provisions of Section 5.2, shall continue until
the earlier of: 


         (a)           20 years from the last Acceptance Date of Capacity 
                  provided hereunder (provided that the grant of IRU hereunder
                  with respect to any Capacity shall not be longer than 20 years
                  from the Acceptance Date for that Capacity pursuant to Article
                  4); or

         (b)           the date on which Globix notifies Qwest in writing that 
                  the Capacity subject to this Agreement has, in Globix's view,
                  reached the end of its economically useful life and that
                  Globix desires to not retain the Globix IRU in such Capacity.

         5.2 Upon the expiration of the Term hereof all of Globix's rights to
the use of the Capacity subject to this agreement shall revert to Qwest without
reimbursement of any fees or other payments previously made with respect
thereto, and from and after such time Globix shall have no further rights or
obligations with respect thereto.

6.  NETWORK ACCESS AND CAPACITY CONFIGURATION

         6.1 Qwest will provide Globix with access to the Capacity at designated
POPs at the city pairs described in Exhibit A hereto.


                                       5
<PAGE>   9
         6.2 In the event that Globix desires to reconfigure the location or
quantity of Capacity it acquires hereunder so as to be different than the
configuration set forth on Exhibit A hereto, Globix shall notify Qwest of its
desired reconfiguration. 

         (a)           Subject to availability, Qwest will implement the
                  reconfiguration of the Capacity as requested by Globix,
                  subject to the following conditions: Subject to the terms set
                  forth in Section 2.5 of this Agreement, Qwest shall have the
                  sole and exclusive discretion to determine whether Globix may
                  have Capacity in excess of OC-48 on any Qwest Network Segment.

         (b)           Subsequent to the initial configuration, a Non-Recurring
                  Charge ("NRC") equal to US$5,000.00 shall be applicable to
                  each reconfiguration which requires the physical rerouting of
                  a circuit on which Capacity is provided. As an example and
                  without limiting the generality of the above, if Capacity is
                  being provided between New York and Los Angeles via Denver,
                  and a new drop and insert point is desired in Denver, no NRC
                  would apply; however, if a new drop and insert point in
                  Chicago were requested, the NRC would apply.

         (c)           Qwest shall recompute the V&H Miles utilized by the
                  reconfigured Capacity. If the quantity of V&H Miles utilized
                  by the reconfigured Capacity is less than the quantity of V&H
                  Miles before the reconfiguration, Qwest shall not pay Globix
                  for any part of the difference. In the event the quantity of
                  V&H Miles utilized by the reconfigured Capacity is greater
                  than the quantity of V&H Miles before the reconfiguration,
                  Globix shall pay to Qwest for the difference: at the rate of
                  US$1.50 per DS-0 V&H Mile for a configured segment.

7.  OPERATIONS

         7.1 Except as may be expressly set forth in this Agreement, the grant
of any IRU under this Agreement shall not provide the recipient of the IRU any
authority to control any network and service configuration or designs, routing
configurations, regrooming, rearrangement or consolidation of channels or
circuits or any related functions with regard to the Qwest Network.

         7.2 At any time during the term of this Agreement, by not less than 120
days written notice to Globix, Qwest, with Globix's prior written approval
(which approval shall not be unreasonably delayed or withheld) may substitute
for the Capacity being provided on any Qwest Network Segment, an equal amount of
Capacity along an alternative route; provided that in any such event, such
substitution (i) shall be without unreasonable interruption of service and use,
(ii) shall be at the sole cost of Qwest including, without limitation, all
disconnect and reconnect costs, fees and expenses, (iii) shall be in accordance
with the specifications set forth in Exhibit B, and (iv) shall not result in an
adverse change to the operations, performance, or connection points of Globix's
business or network.

8.  MAINTENANCE AND RESTORATION OF QWEST CAPACITY

         8.1 Qwest will provide or cause to be provided maintenance for the
Qwest Capacity using its standard maintenance procedures, which procedures shall
be consistent with telecommunications industry standards. The monthly charge for
maintenance of the Qwest Capacity between all the domestic city pairs identified
in Exhibit A hereto excluding the Houston-Washington, D.C. city pair shall be
Thirteen Thousand Two Hundred Eighty Two U.S. Dollars (US $13,282.00) (the
"Domestic Maintenance Fee"). In the event that Globix exercises the Upgrade
Option, the Domestic Maintenance Fee shall thereafter be U.S. Dollars (US
$39,845.00). The monthly charge for maintenance of the Qwest Capacity between
the international city pair identified in Exhibit A hereto (the "International
Maintenance Fee") shall be Ten Thousand U.S. Dollars (US $10,000.00). From the
Effective Date to the first anniversary of the Effective date, the monthly
charge that Globix shall pay to Qwest for maintenance of the Qwest Capacity
shall be the sum of (i) the Domestic Maintenance Fee multiplied by the quantity
of DS-3 V&H Miles of Capacity that Globix has accepted and divided by the Total
IRU DS-3 V&H Miles and (ii) the International Maintenance Fee. Beginning on the
first anniversary of the Effective Date, the monthly charge for maintenance
shall be the greater of (i) the sum of the International Maintenance Fee and the
Domestic Maintenance Fee (the "Minimum Maintenance Fee") or (ii) the sum of (a)
the International Maintenance Fee and (b) the number of DS-0 V&H Miles of
Capacity between domestic city pairs made available to Globix hereunder
multipled by US$0.0035 (the "Monthly Maintenance Rate"). The Minimum Maintenance
Fee and the Monthly Maintenance Rate shall be subject to an annual CPI
adjustment, beginning on the first anniversary of the Effective Date based on
increases in the United States Bureau of Labor Statistics, CPI-U All Services
Index; provided that the annual adjustment shall not exceed 3%.

         8.2 Qwest will use reasonable commercial efforts to provide the
maintenance services described in this Article. Such maintenance does not ensure
the continuous operation of the Qwest Capacity in accordance with the
specifications set forth in Exhibit B at all times during the Term. Globix
acknowledges that service interruptions, outages, or degradations may occur, and
agrees that any such event shall not constitute a default by Qwest under this
Agreement.

         8.3 GLOBIX ACKNOWLEDGES THE POSSIBILITY OF AN UNSCHEDULED, CONTINUOUS
AND/OR INTERRUPTED PERIOD OF TIME WHEN ANY OR ALL CAPACITY PROVIDED HEREUNDER IS
"UNAVAILABLE" (AS DEFINED IN THE SPECIFICATIONS SET FORTH IN EXHIBIT B)
(HEREAFTER AN "OUTAGE"). IN THE EVENT OF AN OUTAGE, GLOBIX SHALL BE ENTITLED TO
A CREDIT (THE "OUTAGE CREDIT") DETERMINED ACCORDING TO THE FOLLOWING: $45 PER
HOUR FOR AN OUTAGE FOR A DS-3; $137 PER HOUR FOR AN OUTAGE FOR AN OC-3; AND $550
PER HOUR FOR AN OUTAGE FOR AN OC-12; $2,200 PER HOUR FOR AN OUTAGE FOR AN OC-48.
CAPACITY SHALL BE "unavailable" for at least two consecutive hours before an
Outage Credit shall apply. The Outage Credit shall apply to the monthly
Maintenance Fee or, at Globix's discretion, toward any future purchase of
Capacity under separate terms and conditions. The length of each Outage shall be
calculated in hours and shall include fractional portions thereof. An Outage
shall be deemed to have commenced upon verifiable notification thereof by Globix
to Qwest, or, when indicated by network control information actually known to
Qwest network personnel, whichever is earlier. Each Outage shall be deemed to
terminate upon restoration of the affected Globix IRU as evidenced by
appropriate network tests by Qwest. Qwest shall give notice to Globix of any
scheduled outage as early as is practicable, and a 


                                       7
<PAGE>   11
scheduled outage shall under no circumstance be viewed as an Outage hereunder.
Outage Credits shall not be granted if the malfunction of any end-to end circuit
is due to an Outage or other defect occurring in Globix's interconnection with
the Qwest Network. Following receipt of Globix's request for credit and at
Globix's discretion, all Outage Credits shall either be a credit towards (1) the
Monthly Maintenance Fee on the next monthly invoice for the affected Capacity,
or (2) future purchases of Capacity under separate terms and conditions . The
total of all Outage Credits applicable to or accruing in any given month shall
not exceed the amount payable by Globix to Qwest for that same month for such
Capacity. The Outage Credit described in this Section shall be the sole and
exclusive remedy of Globix in the event of any Outage, and under no circumstance
shall an outage be deemed a default under this Agreement.

         8.4 Globix shall notify Qwest to report an Outage by using the contact
numbers on the "Escalation and Contact List" appended hereto as Exhibit C.
Globix shall call the 24 Hours Response "Hot-Line" (First Level Escalation) and
send a facsimile to the Ring Operations Center to report an Outage.

         8.5 Qwest shall use commercially reasonable efforts to ensure and
certify that all vendor software and/or hardware used in connection with the
Services provided hereunder are fully Year 2000 compliant.

9.  ACCESS TO QWEST POPS 

         9.1 Globix and its designees (such as local telecommunications
providers) shall have access, according to standards reasonable in the
telecommunications industry, to the Qwest POPs at the endpoints of each Qwest
Network Segment and shall have the right to interconnect with Qwest's Capacity
according to the standards and procedures regularly established by Qwest.

10. USE OF QWEST CAPACITY

         10.1 Globix warrants that its use of the Qwest Capacity shall comply
with all applicable government codes, ordinances, laws, rules, regulations
and/or restrictions.

         10.2 Globix agrees and acknowledges that this Agreement grants no right
to use any element of the Qwest Network other than the Capacity granted herein.
Globix shall keep any and all of the Qwest Network, other than the Capacity,
free from any liens, rights or claims of any third party attributable to Globix
that materially, adversely affect or impair Qwest's exclusive use of the Qwest
Network.

         10.3 Globix shall be responsible for its own configuration and use of
the Qwest Capacity; including the provision of all interconnection facilities,
network equipment, testing equipment and procedures, maintenance, and other
facilities or actions necessary to utilize the Qwest Capacity. Globix shall
conduct all such operations and use of the Qwest Capacity in manner which does
not interfere with the operations of the Qwest Network or the use thereof by any
other customer of Qwest. Globix shall comply at all times with the operating
procedures and interconnection requirements of Qwest. 


                                       8
<PAGE>   12
         10.4 Globix shall include in each Globix agreement or tariff covering
any service provided to any third party through use of the Qwest Capacity a
provision which has the legal consequence of limiting the liability of Globix
thereunder for interruptions, failures, or degradation of service to the charges
received by Globix for such service.

         10.5 Globix 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. INDEMNIFICATION                                                     

         11.1 Subject to the provisions of Article 12, Qwest hereby releases and
agrees to indemnify, defend, protect and hold harmless Globix, its employees,
officers, directors, agents, shareholders and affiliates, from and against, and
assumes liability for:

         (a)      Any injury, loss or damage to any person, 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, licensees, invitees or vendors arising
                  out of or in connection with a default by Qwest in the
                  performance of its obligations under this Agreement;

         (b)      Any claims, liabilities or damages 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; and

         (c)      Any claims, liabilities or damages arising out of any
                  interference with or infringement of the rights of any third
                  party as a result of Globix's use of the IRU and the Capacity
                  in accordance with the provisions of this Agreement.

         11.2 Subject to the provisions of Article 12, Globix hereby releases
and agrees to indemnify, defend, protect and hold harmless Qwest, its employees,
officers, directors, agents, shareholders and affiliates, from and against, and
assumes liability for:

         (a)      Any injury, loss or damage to any person, 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 Globix, its officers, employees, servants, affiliates,
                  agents, contractors, licensees, invitees or vendors arising
                  out of or in connection with a default by Globix in the
                  performance of its obligations under this Agreement;

         (b)      Any claims, liabilities or damages arising out of any
                  violation by Globix 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
                  Capacity hereunder; and


                                       9
<PAGE>   13
         (c)      Any claims, liabilities or damages arising out of any
                  interference with or infringement of the rights of any third
                  party as a result of Globix's use of the IRU and/or the
                  Capacity not in accordance with the provisions of this
                  Agreement.

         11.3 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
the right to bring an arbitration proceeding pursuant to the terms of this
Agreement against the other party for its damages as a result of the other
party's said failure to indemnify, defend, protect and save harmless. These
obligations shall survive the expiration or termination of this Agreement.

         11.4 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
construction, operation or use of the Capacity or the Qwest Network; 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.

12. LIMITATION OF LIABILITY; DISCLAIMER OF WARRANTEE

         12.1 Qwest warrants that the Capacity shall operate in accordance with
the standards established by Qwest for the Qwest Network generally (hereinafter
the "Technical Standards"). If Qwest determines that the Capacity is not being
provided in accordance with the Technical Standards, Qwest shall use reasonable
efforts under the circumstances to conform the Capacity to the Technical
Standards.

         12.2 THE WARRANTIES CONTAINED IN SECTION 12.1 OF THIS AGREEMENT ARE
EXCLUSIVE AND IN LIEU OF ALL OTHER WARRANTIES, WHETHER EXPRESS, IMPLIED OR
STATUTORY, INCLUDING WITHOUT LIMITATION IMPLIED WARRANTIES OF MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE. QWEST HEREBY SPECIFICALLY DISCLAIMS ANY
LIABILITY TO GLOBIX FOR INTERRUPTIONS AFFECTING THE CAPACITY FURNISHED HEREUNDER
WHICH ARE ATTRIBUTABLE TO GLOBIX'S INTERCONNECTION FACILITIES OR TO GLOBIX'S
EQUIPMENT FAILURES, OR TO GLOBIX'S BREACH OF THIS AGREEMENT.

         12.3 Notwithstanding any provision of this Agreement to the contrary,
in no event shall Qwest or any of its Affiliates be liable to Globix or any of
its Affiliates or employees or to any third party for: (a) any loss of profit or
revenue, or for any indirect, consequential, incidental, punitive or similar or
additional damages, whether incurred or suffered as a result of unavailability
of facilities or Capacity, performance, non-performance, termination, breach, or
other action or inaction under this agreement, or for any other reason, even if
Globix advises 


                                       10
<PAGE>   14
Qwest of the possibility of such loss or damage; or (b) for any outage or
incorrect or defective transmissions, or any direct or indirect consequences
thereof.

13. INSURANCE

         13.1 During the term of this Agreement, Globix shall obtain and
maintain, at its expense, an appropriate insurance policy with terms and
coverage thresholds equal to or greater than the industry standard for major
global telecommunications carriers for protection against all risks associated
with the Capacity as reasonably deemed necessary by Globix acting reasonably.

14. LATE PAYMENTS AND PERFORMANCES

         14.1 In the event a party shall fail to make any payment under this
Agreement when due, such amounts shall accrue interest, from the date such
payment is due until paid, including accrued interest, at an annual rate equal
to one hundred fifty percent (150%) of the prime rate of interest published by
The Wall Street Journal as the base rate on corporate loans posted by a
percentage of the nation's largest banks on the date any such payment is due or,
if lower, the highest percentage allowed by law.

15. LIMITATION ON IRU GRANT

         15.1 Although the IRU permits non-cancelable use thereof, the IRU
granted in this Agreement does not provide Globix with any ownership or other
posessory interests in any real property, conduit, fiber, or equipment in or on
the Qwest Network or along the routes of the Qwest Network.

16. TAXES, FEES AND OTHER GOVERNMENTAL IMPOSITIONS

         16.1 Each party shall be independently responsible for any Impositions
properly payable with respect to the Capacity acquired by said party pursuant to
the IRU Agreement entered into hereunder. Further, the parties agree that they
will cooperate with each other and coordinate their mutual efforts concerning
audits, or other such inquiries, filings, reports, etc., as may relate solely to
the activities or transactions arising from or under this Agreement, which may
be required or initiated from or by any duly authorized governmental tax
authority.

18. CONFIDENTIALITY

         18.1 Qwest and Globix hereby agree that if either party provides
confidential or proprietary information to the other party ("Proprietary
Information"), such Proprietary Information shall be held in confidence, and the
receiving party shall afford such Proprietary Information the same care and
protection as it affords generally to its own confidential and proprietary
information (which in any case shall be not less than reasonable care) in order
to avoid disclosure to or unauthorized use by any third party. This Agreement,
including all of the terms, conditions and provisions hereof, constitutes
Proprietary Information, and all information disclosed by either party to the
other in connection with or pursuant to this Agreement shall be deemed to be
Proprietary Information, provided that written information is clearly marked in
a conspicuous place as confidential or proprietary, and verbal information is
indicated as being confidential or proprietary when given or promptly confirmed
in writing as such thereafter. All Proprietary Information, unless otherwise
specified in writing, shall remain the property of the disclosing party, shall
be used by the receiving party only for the intended purpose, and such written
Proprietary Information, including 


                                       12
<PAGE>   16
all copies thereof, shall be returned to the disclosing party or destroyed after
the receiving party's need for it has expired or upon the request of the
disclosing party. Proprietary Information shall not be reproduced except to the
extent necessary to accomplish the purposes and intent of this Agreement, or as
otherwise may be permitted in writing by the disclosing party.

         18.2 The foregoing provisions of Section 18.1 shall not apply to any
Proprietary Information which (i) becomes publicly available other than through
the recipient; (ii) is required to be disclosed by a governmental or judicial
law, order, rule or regulation; (iii) is independently developed by the
disclosing party; or (iv) becomes available to the disclosing party without
restriction from a third party. If any Proprietary Information is required to be
disclosed pursuant to the foregoing clause (ii), the party required to make such
disclosure shall promptly inform the other party of the requirements of such
disclosure.

         18.3 Notwithstanding Sections 18.1 and 18.2 of this Article, either
party may disclose Proprietary Information to its employees, agents, and legal,
financial, and accounting advisors and providers (including its lenders and
other financiers) to the extent necessary or appropriate in connection with the
negotiation and/or performance of this Agreement or its obtaining of financing,
provided that each such party is notified of the confidential and proprietary
nature of such Proprietary Information and is subject to or agrees to be bound
by similar restrictions on its use and disclosure.

         18.4 The provisions of this Article 18 shall survive expiration or
termination of this Agreement.

19. DEFAULT

         19.1 A party shall be in default under this Agreement sixty (60) days
after the non-defaulting party shall have given written notice of such default
unless the defaulting party shall have cured such default or such default is
otherwise waived by the non-defaulting party within such sixty (60) days;
provided, however, that where any such default other than the payment of money
cannot reasonably be cured within such 60-day period, if the defaulting party
shall proceed promptly to cure the same and prosecute such cure with due
diligence, the time for curing such default shall be extended for such period of
time not to exceed one hundred twenty (120) days as may be necessary to complete
such cure.

         19.2 An event of default for Globix also shall include, but not be
limited to, failure to make any payment when due hereunder. Events of default
for Qwest include breach of any material provision hereof, the making of a
general assignment for the benefit of its creditors, the filing of a voluntary
petition in bankruptcy or the filing of a petition in bankruptcy or other
insolvency protection against either party which is not dismissed within ninety
(90) days thereafter, or the filing by either party of any petition or answer
seeking, consenting to, or acquiescing in reorganization, arrangement,
adjustment, composition, liquidation, dissolution, or similar relief.

         19.3 In addition to the specific remedies provided hereunder, upon any
payment or other default by a party, after notice thereof the non-defaulting
party may (i) take such action as it determines, in its sole discretion, to be
necessary to correct the default, and/or (ii) pursue any legal 


                                       13
<PAGE>   17
remedies it may have under applicable law or principles of equity relating to
such default, including, without limitation, the termination of any applicable
IRU Agreement provided that appropriate notice has been given under this section
and any such IRU Agreement. Notwithstanding the above, if the defaulting party
certifies in good faith to the non-defaulting party in writing that a default
has been cured, such default shall be deemed to be cured unless the
non-defaulting party otherwise notifies the defaulting party in writing within
fifteen (15) days of receipt of such notice.

20. TERMINATION

         20.1 Either party may terminate this Agreement upon the failure of the
other party to cure an event of default as required by Article 19. In the event
of a termination of this Agreement by Globix due to Qwest's failure to cure a
default, Qwest shall refund to Globix a pro rata share of the IRU Fee in
accordance with the following formula: Remaining time on the term of Capacity
accepted hereunder multiplied by the amount already paid for such Capacity
divided by 240 months. The period of time remaining on the term of each Capacity
accepted hereunder shall be calculated in months and shall include fractional
portions thereof.

         20.2 Notwithstanding the foregoing, no termination or expiration of
this Agreement shall affect the rights or obligations of any party hereto with
respect to any then existing defaults or the obligation to make any payment
hereunder for services rendered prior to the date of termination or expiration.

21. FORCE MAJEURE

         21.1 Neither party shall be in default under this Agreement if and to
the extent that any 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, material shortages or unavailability or other delay in delivery not
resulting from the responsible party's failure to timely place orders therefor;
lack of or delay in transportation; government codes, ordinances, laws, rules,
regulations or restrictions (collectively, "Regulations"); war or civil
disorder; failure of a third party to grant a required right-of-way permit,
easement, or other required authorization for use of the intended right-of-way,
or any other cause beyond the commercially 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.

22. WAIVER

         22.1 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.

EXHIBIT B: QWEST CAPACITY SPECIFICATIONS AND ACCEPTANCE TESTING

1.   INTERCONNECT SPECIFICATIONS:

1.1  The customer interconnection point of DS-1 & DS-3 signals at the Qwest
     (SPT) location will be at an industry standard (DSX-1) & (DSX-3) digital
     cross-connect panels and will be referred to as Qwest Network Interface in
     this document.

1.2  The DS-1 & DS-3 signals terminating at the Qwest digital cross-connect
     panels will meet the electrical specifications as defined in AT&T
     Compatibility Bulletin (CB) No. 119, Issue 3, October, 1979.

1.3  The Qwest Digital Network will be compatible with the Bell System
     hierarchical clock synchronization methods and stratum levels as described
     in Bellcore Technical Advisory (GR436-Core).

1.4  Customer equipment must also meet the interconnect specifications listed
     above and shall comply with jitter requirements of AT&T Technical Reference
     PUB 63411.

2.   PERFORMANCE OBJECTIVES:

2.1  DS1, DS3, OC-3, OC-12, OC-48, OC-3c, OC-12c, and OC-48c circuit performance
     will be measured using two parameters: Availability and Error-Free Seconds.

     The following assumptions apply to the derived data:

          -    The circuits originate and terminate on the SONET OC-48 backbone

          -    High speed protection switching: 1 for N, where N=2

          -    MTTR for SONET equipment: 2 hours

          -    MTTR for fiber optic cable: 12 hours (Bellcore Standard)

          -    Cable cut rate: 4.39/year/1,000 sheath miles (Bellcore Standard)
               The system includes three (3) DCS in Los Angeles, Sacramento, and
               San Jose (although not all circuits are routed through the DCS,
               they are included in all the calculations)

2.2  Availability is a measure of the relative amount of time during which the
     circuit is available for use. According to CCITT and ANSI definitions,
     unavailability begins when the Bit Error Ratio (BER) in each second is
     worse than 1.0 E-3 for a period of 10 consecutive seconds.

     INTER OFFICE CHANNEL (IOC) : An Inter Office Channel refers to the Qwest
     Communications network between the points of presence (POP).


                                       20
<PAGE>   24
     OPTICAL CARRIER LEVEL 1 (OC-1) : The optical signal that results from an
     optical conversion of an electrical STS-1 signal (51.840 Mb/s). This signal
     forms the basis of the interface.

          OC-3: Optical Carrier level 3 signal operating at 155.520 Mb/s.

          OC-12: Optical Carrier level 12 signal transmitting at 622.080 Mb/s.

          OC-48: Optical Carrier level 48 signal transmitting at 2488.32 Mb/s.

     POINT OF PRESENCE (POP) : A physical location where a long distance carrier
     terminates lines before connecting to the local exchange carrier, another
     carrier, or directly to a customer.

2.3  The availability objective for all circuits between Qwest Network Interface
     points specified above is to provide performance levels over a 12 month
     period as follows:

---------------------------------------------------------------------------------------
</TABLE>

     This excludes any customer provided access links to the Qwest digital
     network.

2.4  Outages attributable to incidental damage to or severage of outside fiber
     optic cable plant, or scheduled maintenance is excluded from the
     performance objective stated above.

2.5  Error-Free Seconds (EFS) and Error Seconds (ES) are the primary measure of
     error performance. An Error-Free Second is defined as any second in which
     no bit errors are received. Conversely, an Error Second is any second in
     which one or more bit errors are received.

3.   SONET: Synchronous Optical Network is a family of optical transmission
     rates and interface standards allowing internetworking of products from
     different vendors. Base optical rate is 51.840 Mb/s. Higher rates are
     direct multiples.

     SONET TRANSPORT: Facilities associated with carrying OC-1 or higher level
     signals.

     SYNCHRONOUS TRANSPORT SIGNAL LEVEL 1 (STS-1): The basic logical building
     block electrical signal with a rate of 51.840 Mb/s.

     SYNCHRONOUS TRANSPORT SIGNAL LEVEL N (STS-N): This electrical signal is
     obtained by byte interleaving N STS-1 signals together. The rate of the
     STS-N is N times 51.840 Mb/s.

     TERMINATING MULTIPLEX (TM) : Provides the multiplex functions for
     multiplexing and demultiplexing between the DS1 or higher signal level and
     the SONET OC-N level.

     ACCEPTANCE CRITERIA. The acceptance criteria for DS1, DS3, OC-3, OC-12,
     OC-48, OC-3c, OC-12c, and OC-48c circuits between Qwest Network Interface
     points is to provide the performance levels shown below during a 60 minute
     test period. If no errors are observed during the first 15 minutes of the
     test, the facility may be considered acceptable. Access connections to
     customer location will be tested in accordance with Bell Publication 62508.

          -    The tables below are based on QCC owned fiber optic network only
               and on the Bellcore Specifications of the SONET delivery of DS1,
               DS3, OC-3, OC-12, OC-48, OC-3c, OC-12c, and OC-48c directly off
               the SONET Backbone.

          -    If the DS1, DS3, OC-3, OC-12, OC-48, OC-3c, OC-12c, and OC-48c
               service is delivered at the STS1 level then the general
               performance objectives fall into the industry standard.

     DS1, DS3 The table below defines the general performance objectives for DS1
     service operating at 1.544 Mb/s, and the general performance objectives for

                  EXHIBIT D: QWEST CAPACITY TECHNOLOGY UPGRADE

1. Qwest's current network technology consists of Nortel's four-fiber
bi-directional SONET ring architecture on two fiber strands. It is 8 lambda
technology (4 lambdas in each direction per fiber). For purposes of this
Agreement, an "upgrade" to this system shall mean an improvement on this
technology to, for example, 16 or 32 lambda technology allowing Qwest to derive
more capacity from the same fibers as those carrying Globix's IRU.

2. Proportional share of capacity shall be determined as follows: For example,
assuming Globix has purchased an OC3 on a segment where Qwest is using 8 lambda
technology. Globix's proportional share is 3/(4*192), or 0.39%. If Qwest
upgrades to 16 lambda technology, Globix shall be eligible to purchase one (1)
additional OC3 (0.39% of total system capacity) on the portion upgraded. If
Qwest upgrades to 32 lambda technology, Globix shall be eligible to purchase an
additional three (3) OC3's (1.17% of total system capacity).

3. Proportional cost shall be determined as follows: If Globix were eligible to
purchase an additional OC3 because of Qwest's upgrade to 16 lambda technology,
Globix shall pay to Qwest 0.39% of Qwest's total cost of such upgrade. Total
equipment and installation costs for such upgrade shall include without
limitation transport gear and terminal equipment (optronics), tributary cards
associated with Globix's bandwidth requirements, incremental land & buildings
required to house the upgraded equipment, installation required for the upgrade,
and other miscellaneous costs associated with and required to install the
upgrade without mark-up. Engineering and other overhead costs shall also be
included when computing the total cost to Globix.

4. Once complete, Qwest's network will be SONET ring-protected. In the event of
a Qwest upgrade, Qwest must install upgraded SONET ring equipment in all sites
on a particular ring, not just on a particular segment. The capacity purchased
by Globix is ring-protected, as such, Globix's proportional share of the total
costs shall be based on Qwest's total cost to upgrade the ring or rings. The
proportion is still determined based on Note 3, but the total cost will include
costs to upgrade the entire ring.
