                            GTE TELECOM INCORPORATED
                               CAPACITY AGREEMENT

This CAPACITY AGREEMENT is made and entered into as of August 20, 1999, by and
between GTE Telecom Incorporated (hereinafter referred to as "TELECOM" or
Party), a Delaware corporation with principal offices at 201 N. Franklin Street,
Suite 2400, Tampa, Florida 33602; and Universal Access, Inc. (hereinafter
referred to as "CUSTOMER" or Party), with offices at 100 N. Riverside Plaza,
Suite 2200, Chicago, Illinois 60606 for the provision of capacity and related
ancillary telecommunications services (hereinafter referred to as "Services") as
described herein and accepted by CUSTOMER under this Agreement, subject to the
terms and conditions contained herein. This Capacity Agreement together with any
Capacity Descriptions (as described in Section 1 below) accepted by TELECOM
pursuant to the terms hereof shall be referred to collectively as the
"Agreement".

1. SERVICE REQUESTS/CAPACITY DESCRIPTIONS: Requests for Services to be provided
hereunder shall be issued by CUSTOMER from time to time on TELECOM Capacity
Description Form(s) (hereinafter referred to as a "CD", a copy of which is
attached hereto and made a part hereof as Exhibit 1). Each CD shall reference
this Capacity Agreement by CA Number. Such CDs shall be effective when accepted
in writing by TELECOM and shall become part of this Agreement to the extent that
they specify the type of Service to be provided, quantity of circuits,
originating and terminating cities, requested service date, Service Term,
recurring and non-recurring charges for provision of Service, and other
information necessary for TELECOM to provide Service to the CUSTOMER. No action
by TELECOM (including, without limitation, provision of Service to CUSTOMER
pursuant to such CD) shall be construed as binding or estopping TELECOM with
respect to such term or condition, unless the CD containing said specific term
or condition has been duly executed by an authorized representative of TELECOM.

2. EFFECTIVE DATE AND APPLICATION OF THIS AGREEMENT: This Agreement shall be
effective between the parties as of the date first written above. The applicable
Rates and Charges are set forth in Exhibit 2 attached hereto and made a part
hereof. This Agreement shall apply exclusively to the Service provided to
CUSTOMER pursuant to the CD(s) identified with this Agreement and accepted by
TELECOM, for the Service Term stated therein and any automatic extensions
thereof. Services are provided subject to availability and TELECOM reserves the
right not to accept a CD under this Agreement at any time.

3. SERVICE TERM: (a) After a CD is accepted by TELECOM, a Firm Order
Confirmation Date ("FOC" Date) will be scheduled for Service installation. The
Service Term for Services subject to recurring charges and described in a CD
shall commence on the Firm Order Confirmation Date or the date upon which the
Service actually becomes available (the "In Service" Date), in conformity with
technical standards, whichever is later. The Service being provided hereunder
will be released to CUSTOMER for testing for seventy-two (72) hours prior to the
In Service Date.

 (b) TELECOM will make reasonable efforts to meet the CUSTOMER requested In
Service Date, however, the inability of TELECOM to install Service on or before
the date requested shall not be a Default under this Agreement. Except for any
installation delays caused by those events described in Section 12 below, in the
event Service installation is delayed for ninety (90) days beyond the CUSTOMER
requested In Service Date with respect to each Service ordered, then CUSTOMER's
sole remedy shall be cancellation of the CD which pertains to such Service upon
ten (10) calendar days prior written notice to TELECOM. Cancellation charges
described in Section 11 below shall not apply to such cancellation.

 (c) Upon expiration of the Service Term set forth in the CD, if CUSTOMER is not
then in Default under this Agreement, Service will automatically be extended for
continuing thirty (30) day periods and may be canceled by either party upon
thirty (30) calendar days prior written notice. Unless otherwise agreed to in
writing, the charges for Service during any such extension shall be the then
current TELECOM month to month rate for such Services.



                                                                               1

 (d) Price Protection Commencing [***] months after the effective date of the
Agreement and continuing thereafter semi-annually at the semi-annual date of the
Agreement, CUSTOMER may request TELECOM to review the prices contained in the
CD(s) entered into between the parties if the CUSTOMER has received an offer
from a qualified vendor (i.e., a vendor that is suitable to the CUSTOMER that
has obtained any required licenses, approvals or other authorizations) for all
Services provided hereunder which reduces the total prices by [***] or greater.
TELECOM reserves the right to review such an offer, subject to confidentiality
or non-disclosure obligations imposed on CUSTOMER in connection therewith, and
if warranted, will enter into negotiations with CUSTOMER for a reduction in
price.

4. DESCRIPTION OF SERVICES: As specified in the CD accepted by TELECOM
hereunder, TELECOM will provide to CUSTOMER the following Services:

6. CUSTOMER RESPONSIBILITIES: CUSTOMER has sole responsibility for installation,
testing, and operation of facilities, services, and equipment other than those
specifically provided by TELECOM under a duly accepted CD. In no event will the
untimely installation or non-operation of CUSTOMER's facilities, services, and
equipment (including local exchange access and customer premise equipment)
relieve CUSTOMER of its obligation to pay charges for Capacity or Ancillary
Service as of the In Service Date. Notwithstanding the immediately preceding
sentence, CUSTOMER may request one extension of the In Service Date for not more
than thirty (30) calendar days. Such requests for extension of local exchange
access together with the interexchange portion of the Service must be in writing
and must be received by TELECOM at least ten (10) calendar days prior to the
initial FOC Date established by TELECOM. Written requests for extension of the
In Service Date for the interexchange portion only must be and must be received
by TELECOM at least five (5) calendar days prior to the initial FOC Date
established by TELECOM. Any such extension will not relieve CUSTOMER of its
obligations to pay charges for any local access services ordered by TELECOM on
behalf of CUSTOMER as of the FOC Date first established by TELECOM.

7. PAYMENT OF CHARGES: (a) Subject to Section 8 below, all charges for Services
provided by TELECOM pursuant to this Agreement shall be specified in the CD
referred to in this Agreement.

(b) CUSTOMER shall pay each TELECOM invoice for Service in full, without
deduction or offset of any kind, within thirty (30) days after the date of
invoice ("Due Date"); provided however, if CUSTOMER in good faith disputes any
portion of an invoice, it must pay the undisputed amount on or before the Due
Date and provide written notice to TELECOM of the billing dispute within ninety
(90) days thereafter. Such notice must include documentation substantiating the
dispute. CUSTOMER's failure to notify TELECOM of a dispute shall be deemed to be
CUSTOMER's acceptance of such charges. The Parties will make a good faith effort
to resolve billing disputes as expeditiously as possible. If a dispute is
resolved in favor of CUSTOMER, CUSTOMER shall receive a credit on its invoice
within a commercially reasonable period of time for the disputed amount and any
related fees or penalties. All pro-rated monthly recurring charges (i.e.,
charges for monthly Services provided for less than a calendar month),
installation, and other non-recurring charges shall be payable on the Due Date.
All payment shall be made in US dollars. CUSTOMER agrees to timely remit payment
to TELECOM at the remittance address indicated on the TELECOM invoice to
CUSTOMER.

(c) Except for any reasonably disputed amount, in the event CUSTOMER fails to
pay TELECOM's invoice in full or remit payment at the proper address on or
before the Due Date, CUSTOMER shall pay a late fee in an amount equal to one and
one-half percent (1 1/2%) per month of the unpaid balance. The late fee will be
applied for the number of days from the payment Due Date up to and including the
date payment is received by TELECOM. Notwithstanding the foregoing, late fees
shall apply to, but shall not be due and payable for, amounts reasonably
disputed by CUSTOMER provided: (i) CUSTOMER notifies TELECOM of the basis of
such dispute in writing within sixty (60) days after the Due Date and (ii)
negotiates in good faith with TELECOM for the purpose of resolving such dispute.
In the event such dispute is resolved in favor of TELECOM, CUSTOMER will pay to
TELECOM the once disputed amount together with the applicable late fees. In the
event the dispute is resolved in favor of the CUSTOMER, CUSTOMER will receive a
credit for the amounts determined not to be owed together with a credit for the
applicable late fees. The Parties shall use their best efforts to negotiate in
good faith to resolve the disputed invoice within thirty (30) days of CUSTOMER's
written notice of such dispute. If such resolution is not attained or the time
to resolve the dispute is not extended by mutual agreement of the Parties, the
dispute shall be settled by arbitration as set forth below in this Agreement.

(d) TELECOM may, in order to safeguard its interests, require CUSTOMER which has
no credit history with TELECOM or habitually pays late to make a deposit prior
to or any time after the provision of Service to the CUSTOMER to be held by
TELECOM as a guarantee of the payment of the rates and charges. In lieu of such
a deposit, TELECOM may accept an unconditional, irrevocable Letter of Credit in
a form acceptable to TELECOM in an amount required by TELECOM, subject to
increase from time to time as CUSTOMER orders additional circuits hereunder. At
such time as the provision of the Service to CUSTOMER is terminated, the amount
of the deposit will be credited to the CUSTOMER's account and any credit balance
which may remain will be refunded. After the CUSTOMER has established a six (6)
month prompt payment record, such deposit may be refunded or credited to the
CUSTOMER account at any time prior to the termination of the provision of the
Service to CUSTOMER. In the event CUSTOMER pays a deposit as described above,
simple interest at the rate of six percent (6%) will be



                                                                               3
<PAGE>   4

applied to the deposit for the number of days from the date such deposit is
credited to the CUSTOMER'S account or the date the deposit is refunded by
TELECOM.

8. TAXES/ADDITIONAL CHARGES: (a) CUSTOMER acknowledges and understands that all
charges stated in the CD are computed by TELECOM exclusive of any applicable
federal, state, or local use, excise, gross receipts, sales, and privilege
taxes, duties, fees, including but not limited to applicable Universal Service
Fund contributions, or similar liabilities (other than general income or
property taxes), whether charges to or against TELECOM or CUSTOMER because of
the Service furnished by TELECOM ("Additional Charges"), and that such
Additional Charges shall be paid by CUSTOMER in addition to all other charges
provided for herein.

(b) Such taxes, surcharges or fees shall be separately stated on the invoice and
shall be paid directly to TELECOM at the same time as all other charges are due
and payable in accordance with this Agreement. Simultaneous with the signing of
this Agreement, CUSTOMER shall provide TELECOM with a valid Certificate of
Exemption from taxes that would otherwise be paid by CUSTOMER for all foreign,
federal, state, country and local taxes and fees, (if any) or other evidence
reasonably satisfactory to TELECOM that CUSTOMER is not subject to such taxes,
surcharges, or fees. TELECOM will invoice CUSTOMER for taxes that are not
covered by a valid tax exempt certificate properly filed with TELECOM.

9.      EARLY TERMINATION: (a) Either Party may terminate this Agreement if:

                (i)   the other Party ceases doing business as a going concern,
                      makes an assignment for the benefit of creditors, admits
                      in writing to its inability to pay its debts as they
                      become due; or

                (ii)  the other Party files a voluntary petition in bankruptcy,
                      is adjudicated a bankrupt or an insolvent; or

                (iii) the other Party files a petition seeking for itself any
                      reorganization, arrangement, composition, readjustment,
                      liquidation, dissolution or similar arrangement under any
                      present or future statute, law or regulation or files an
                      answer admitting the material allegations of a petition
                      filed against it in any such proceeding; or

                (iv)  the other Party consents or acquiesces in the appointment
                      of a trustee, receiver, or liquidator of it or of all or
                      any substantial part of its assets or properties, or it or
                      its shareholders shall take any action looking to its
                      dissolution or liquidation;

                (v)   the other Party breaches any material provision of this
                      Agreement, other than those related to payment of charges,
                      and fails to cure such breach within thirty (30) calendar
                      days after the receipt of notice thereof ("Default").

(b) Both Parties may terminate this Agreement upon mutual written consent.

10. SUSPENSION OF SERVICE: (a) In the event payment in full is not received from
CUSTOMER on or before the Due Date with respect to any undisputed amounts,
TELECOM shall have the right, after giving CUSTOMER fifteen (15) days written
notice via express courier service or registered mail, to suspend all or any
portion of Service until such time as CUSTOMER has paid in full all charges then
due, including any late fees as specified herein.

(b) Following such payment, TELECOM shall be required to reinstate Service to
CUSTOMER only upon CUSTOMER's provision to TELECOM of satisfactory assurance
(such as a deposit) of CUSTOMER's ability to pay for Service and CUSTOMER's
advance payment of the cost of reinstating Service. If CUSTOMER fails to make
such payment by a date determined by and acceptable to TELECOM, CUSTOMER will be
deemed to have canceled the suspended Service effective the date of the
suspension. Upon such termination, all balances become due and payable.

11. CANCELLATION OF SERVICE: (a) CUSTOMER may cancel a CD without liability if a
Service does not become available within ninety (90) days of the FOC Date as
described in Section 3 (b) above.



                                                                               4
<PAGE>   5
 (b)  After a CD is submitted to TELECOM by the CUSTOMER except as noted in
Section 3(b) above, CUSTOMER may cancel all or a portion of the Services ordered
upon written notice to TELECOM. The charges for such Cancellation are as
follows:


Prior to issuance of the FOC           No Cancellation Charges



Subsequent to issuance of the FOC      50% of applicable MRC for one (1) month
        up to the FOC Date             (maximum $20,000)


(c) It is agreed that TELECOM's damages in the event of a cancellation can be
difficult or impossible to ascertain. The provision for cancellation charges in
this subsection is intended to establish liquidated damages in the event of
Service cancellation and is not intended as a penalty. Unless otherwise stated
in the CD and specifically agreed to in writing by both Parties, in the event
CUSTOMER cancels existing Service prior to the end of the Service Term described
in the CD, CUSTOMER shall pay TELECOM an amount equal to the balance of the
monthly Service charges that otherwise would have become due for the unexpired
portion of the Service Term ("Cancellation Charges/Early Cancellation Charges").
Notwithstanding the immediately preceding sentence, no Early Cancellation
charges shall apply for the cancellation of the interexchange Service on
Telecom's Network for period that the CUSTOMER is responsible for the payment of
the Minimum Monthly Recurring Charge as set forth in Exhibit 2 - Rates and
Charges.

(d) Notwithstanding the foregoing, and upon thirty (30) days prior written
notice, either Party shall have the right, without cancellation charge or
liability, to cancel (i) an affected portion of the Service, if TELECOM is
prohibited by governmental authority from furnishing said portion, or (ii) an
affected portion of the Service if any material rate or term contained herein is
substantially changed by final order of a court of competent jurisdiction, the
Federal Communication Commission, or other local, state or federal government
authority.

12. FORCE MAJEURE: If either Party's performance of this Agreement or any other
obligation hereunder (other than the obligation to make payments for amounts
due) is prevented, restricted or interfered with by causes beyond their
reasonable control including but not limited to acts of God, fire, explosion,
vandalism, cable cut, storm, or other similar occurrence, any law, order,
regulation, direction, action or request of the United States government or
state or local government, or of any department, agency, commission, court,
bureau, corporation or other instrumentality of any one or more said
governments, or civil or military authority, or by national emergencies,
insurrections, riots, wars, strikes, lockouts or work stoppages or other labor
difficulties, actions or inactions of a third party provider or operator of
facilities employed in the provision of the Services, suppliers' failures,
shortages, breaches, or delays, then the affected Party shall be excused from
such performance on a day-to-day basis to the extent of such prevention,
restriction, or interference. The affected 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 cease.

13. SERVICE WARRANTY: TELECOM warrants that it will provide the Service to
CUSTOMER in accordance prevailing telecommunication industry standards
(hereinafter "Technical Standards"). TELECOM will use reasonable efforts under
the circumstances to remedy any delays, interruptions, omissions, mistakes,
accidents or errors in any Service and restore the Service in accordance with
Technical Standards. THE FOREGOING WARRANTY IS EXCLUSIVE AND IN LIEU OF ALL
OTHER WARRANTIES, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING WITHOUT
LIMITATION IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.

14. LIMITATION OF LIABILITY: TELECOM shall not be liable for interruptions,
delays, errors, or defects in transmission caused by the CUSTOMER, or the
CUSTOMER's agents, end users, or by facilities or equipment provided by the
CUSTOMER or by equipment interconnected with the CUSTOMER. UNDER NO
CIRCUMSTANCES, WHETHER IN CONTRACT TORT OR OTHERWISE, SHALL EITHER PARTY BE
LIABLE FOR ANY INCIDENTAL, INDIRECT, CONSEQUENTIAL, SPECIAL, ACTUAL, PUNITIVE,
OR ANY OTHER DAMAGES OR ANY KIND OR NATURE WHATSOEVER REGARDLESS OF THE CAUSE OR
FORESEEABILITY THEREOF, INCLUDING BUT



                                                                               5

NOT LIMITED TO DAMAGES ARISING FROM DELAY OR LOSS OF DATA, PROFITS, REVENUE OR
GOODWILL.

15. INDEMNIFICATION: Each Party agrees to release, indemnify, defend, and hold
harmless the other Party from losses, claims, demands, damages, expenses, suits,
or other actions, including reasonable attorney's fees, for personal injury,
including death of any person or persons, and for losses, damage, or destruction
of property, to the extent proximately caused by the negligence or willful
misconduct of the indemnifying Party, its employees, contractors, or agents.
This indemnity applies where the indemnifying Party's negligence or willful
misconduct is either the sole or the contributing cause of the injury, death, or
damage. This indemnity does not extend to any portion of the injury, death or
damage caused by either the sole or the contributing negligence of the
non-indemnifying Party or third parties. In the event parties other than
CUSTOMER shall have use or benefit of or shall be otherwise affected by the
Service provided through CUSTOMER, then CUSTOMER agrees to forever indemnify and
hold TELECOM and any third party provider or operator of the facilities employed
in the provision of the Service harmless from and against any and all claims,
demands, suits, actions, losses, damages, assessments or payments which may be
asserted by said parties, arising out of or related to any outage in Service.

17. USE OF SERVICE/CAPACITY: (a) TELECOM's obligation to provide Services
specified herein is conditioned upon CUSTOMER not allowing the Services to be
used for any unlawful purpose or in violation of any governmental regulations or
authorizations. TELECOM shall have the right to limit, terminate or suspend
Service by written notice for improper use of the Service by CUSTOMER or any
activity by CUSTOMER, as determined in the sole discretion of TELECOM, that
threatens public health, safety, or welfare, or the integrity or reliability of
TELECOM's facilities or service to TELECOM's other customers.

(b) If CUSTOMER wishes to purchase capacity in an amount exceeding the
equivalent of OC-12 on any one route, then CUSTOMER represents and warrants that
it is not now, nor shall it become during the Term of this Agreement, a Capacity
Reseller (as defined below) with respect to any Services provided under this
Agreement. If CUSTOMER is or becomes during the Term of this Agreement a
Capacity Reseller with respect to any of the Services purchased hereunder, then
CUSTOMER may not purchase capacity in excess of the equivalent of one OC-12 on
any one route (referred to in this Section as the "Maximum Capacity"). If, at
the time CUSTOMER becomes a Capacity Reseller with respect to the Services
hereunder, CUSTOMER has ordered in excess of the Maximum Capacity, then CUSTOMER
shall immediately terminate all capacity in excess of the Maximum Capacity. Such
termination shall be subject to all applicable Early Cancellation/Termination
Charges. As used herein, a "Capacity Reseller" is any person or entity which, in
whole or in part, seeks to obtain telecommunications



                                                                               6
<PAGE>   7

capacity for the purpose of reselling or otherwise providing access thereto to
third parties for profit, whether or not such person or entity actually realizes
a profit as a result of such transaction. CUSTOMER's failure to comply with this
Section shall constitute a material default and shall be grounds for immediate
termination.

18. NONDISCLOSURE: CUSTOMER shall not use, except as provided herein, nor
disclose to any third party during the Term of this Agreement and for a period
of two (2) years thereafter, any of the terms and conditions relating to this
Agreement, including but not limited to the rates and charges set forth in this
Agreement, unless such disclosure is lawfully required by any federal
governmental agency, is otherwise required to be disclosed by law, or is
necessary in any proceeding establishing the rights and obligations under this
Agreement. Prior to any such required disclosure by CUSTOMER, CUSTOMER shall
provide TELECOM with adequate written notice so as to enable TELECOM to seek
appropriate protection. TELECOM reserves the right to terminate this Agreement
immediately upon written notice of any unpermitted third party disclosure
hereunder.

19. LICENSES, APPROVALS AND AUTHORIZATIONS: CUSTOMER represents that in all
jurisdictions in which it provides services that require licenses, approvals or
other authorizations it has obtained such licenses, approvals or other
authorizations from the appropriate governmental authority. Further, if required
by TELECOM, CUSTOMER shall provide proof of such licenses, approvals or other
authorizations. CUSTOMER shall immediately notify TELECOM in writing, in the
event CUSTOMER is prohibited, either on a temporary or permanent basis, from
continuing to provide its telecommunications services in any jurisdiction. In
such event, TELECOM reserves the right to terminate this Agreement.

20. RESOLUTION OF DISPUTES: The Parties desire to resolve disputes arising out
of this Agreement without litigation. Accordingly, except for action seeking a
temporary restraining order or injunction related to the purposes of this

reimbursement for reasonable attorneys' fees, court costs, costs of

Agreement, in whole or in part, unless such agreement is in writing and signed

CUSTOMER and the terms hereof shall be construed under the laws of the State of

CUSTOMER and TELECOM hereby agree to negotiate with respect to any such invalid
or unenforceable part to the extent necessary to render such part valid and
enforceable.

sense and content are intended to survive the performance thereof by the parties
hereto shall survive the completion of performance and termination of this

                            SERVICE LEVEL OBJECTIVES

TELECOM will make commercially reasonable efforts to meet the following Service
Level Objectives:

(a)     Mean Time to Repair - less than or equal to four (4) hours for DS3's,
        OC3's, OC12's.

(b)     Network Availability for "on net" private line Services:

        99.95% for Linear Network

        99.99% for SONET Ring Network (when available).

Credits for Outages:

(i) For the purposes of this Agreement, a circuit shall be deemed to be in an
"Outage" condition if, following the start of Service while CUSTOMER is actually
using or attempting to use such circuit, the circuit and becomes unavailable as
defined above.

CUSTOMER's request for credit for Outages must be submitted to TELECOM in
writing within thirty (30) calendar days of such Outage. TELECOM will respond to
each of CUSTOMER's requested credits and upon Outage verification by TELECOM,
TELECOM will apply the applicable credit to the next or subsequent Service
invoice. Service Outages do not include (a) Outage periods when CUSTOMER has
released the Service to TELECOM for maintenance purposes or to make
rearrangements or CUSTOMER requested changes in the Service; (b) circuits
outside the contiguous U.S.; (c) any circuits ordered by CUSTOMER from another
telecommunications service provider or carrier; (d) any local access circuits
ordered by or on behalf of CUSTOMER; (e) failure of CUSTOMER applications,
equipment or facilities, (f) acts or omissions of CUSTOMER, or any use or user
of the Service authorized by CUSTOMER or (g) reasons of Force Majeure. [***] No
credit is allowed for Service Outages of less than thirty (30) minutes. Outages
will be credited to CUSTOMER in half hour multiples for each half hour or major
fraction thereof, from the time TELECOM receives notification until Service is
restored. The credit shall not be applicable for the time that TELECOM stands
ready to repair the Service and CUSTOMER does not provide access to TELECOM to
perform such repair and restoration work. The credit allowance for an Outage or
a series of Outages shall not exceed the current monthly recurring charge for
such Service. The credit provided for in this Section shall be TELECOM's sole
liability and CUSTOMER's sole and exclusive remedy in the event of any Outage or
Service interruption.

(ii) Chronic Outages In the event that a single circuit experiences three (3)
or more Outages of fifteen (15) minutes duration or longer during any thirty
(30) day period, CUSTOMER may declare that the circuit has a chronic problem.
Upon written notice from CUSTOMER, TELECOM will have thirty (30) days to correct
the chronic problem. In the event that the problem is not corrected within
thirty (30) days of TELECOM's receipt of written notice, CUSTOMER may cancel
this circuit without any additional charges or any further liability and such
cancellation will be CUSTOMER's sole and exclusive remedy for chronic Outages.

Credit allowances will be calculated on a monthly basis and the applicable
Outage credit by circuit will be included in TELECOM's invoice. CUSTOMER shall
have thirty (30) days from date of receipt of the invoice to contest the credit
allowance offered by TELECOM.



                                                                              12
