              This Addendum IX (this "ADDENDUM") contains amendments to the
Sprint PCS Management Agreement, the Sprint PCS Services Agreement, the Sprint

and Service Mark License Agreement, each of which was entered into on January
22, 1999 by Sprint Spectrum L.P., SprintCom, Inc., WirelessCo, L.P., Sprint
Communications Company L.P. and Illinois PCS, L.L.C. After entering into these
agreements, Illinois PCS, L.L.C. was merged into iPCS Wireless, Inc. on July 12,
2000. The Management Agreement, Services Agreement and Trademark License
Agreements were amended by:

              (1)    Addendum I dated as of January 22, 1999,
              (2)    Addendum II dated as of August 3, 1999,
              (3)    Amended and Restated Addendum III dated as of March 8,
                     2000,
              (4)    Addendum IV dated as of July 12, 2000,
              (5)    Addendum V dated as of December 15, 2000,
              (6)    Addendum VI dated as of February 28, 2001,
              (7)    Addendum VII dated as of August 26, 2002, and
              (8)    Addendum VIII dated as of March 26, 2004.

              The purposes of this Addendum are to (1) acknowledge Manager's
exercise of the Mackinac BTA option referenced in Addendum VIII and (2) update
the Service Area BTAs and Exhibit 2.1 maps, table, and text to reflect the new
additional territory.

              The terms and provisions of this Addendum control over any
conflicting terms and provisions contained in the Management Agreement, the
Services Agreement, the Trademark License Agreements and the Schedule of
Definitions. The Management Agreement, the Services Agreement, the Trademark
Licenses Agreements, the Schedule of Definitions and all prior addenda continue
in full force and effect, except for express modifications made in this
Addendum.

              Capitalized terms used and not otherwise defined in this Addendum
have the meaning ascribed to them in the Schedule of Definitions or in prior
addenda. Section and Exhibit references are to sections and Exhibits of the
Management Agreement unless otherwise noted.

The Management Agreement is modified as follows.

       1.     MACKINAC OPTION. Sprint PCS hereby acknowledges that, effective as
of June 15, 2004, Manager exercised its option to expand its Service Area to
include Sault Ste. Marie, Michigan (BTA #409) and Petoskey, Michigan (BTA #345)
(the "Mackinac BTAs") by delivering notice to Sprint PCS in the form of EXHIBIT
8(b)(i) attached to Addendum VIII and completing the build-out as set forth in
EXHIBIT 8(b)(ii) attached to Addendum VIII, in each case, to the satisfaction of
Sprint PCS. Accordingly, Manager and Sprint PCS hereby agree that the list of
BTAs in Manager's Service Area and Exhibit 2.1 are revised to include the
Mackinac BTAs, as described in Section 2 below, effective as of June 15, 2004.

       2.     REVISED BUILD-OUT. Effective as of June 15, 2004, the Exhibit 2.1
table and narrative description attached to this Addendum supersedes the Exhibit
2.1 table and narrative description attached to Addendum VIII. Effective as of
June 15, 2004, the Exhibit 2.1 map for Michigan attached to this Addendum
supersedes the Exhibit 2.1 map for Michigan (Exhibit 2.1 Map part 2 of 3)
attached to Addendum VIII. The maps for Illinois and Iowa and Nebraska attached
to Addendum VIII (Exhibit 2.1 Map part 1 of 3 and 3 of 3, respectively) remain
unchanged.

       2.     COUNTERPARTS. This Addendum may be executed in one or more
counterparts, including facsimile counterparts, and each executed counterpart
will have the same force and effect as an original instrument as if the parties
to the aggregate counterparts had signed the same instrument.

            [THE REMAINDER OF THIS PAGE IS LEFT BLANK INTENTIONALLY.]

date first above written.

              MASTER TOWER SPACE RESERVATION AND LICENSE AGREEMENT

This Master Tower Space Reservation and License Agreement (this "Agreement") is
entered into as of the 20th day of July 2002 by and between American Tower,
L.P., a Delaware limited partnership, with an address at 116 Huntington Avenue,
Boston, MA 02116 (hereinafter referred to as the "Licensor"), and iPCS Wireless,
Inc., a Delaware corporation, with an address at 233 Peachtree Street, N.E.,
Harris Tower Suite 1700, Atlanta, Georgia 30303 (hereinafter referred to as the
"Licensee").

                                   BACKGROUND

From time to time Licensee and/or its Affiliates may have the need to reserve or
license space on communication towers then-owned or operated by Licensor and/or
its Affiliates. This Agreement sets forth the terms and conditions by which
Licensee may request to reserve or license space on a communication tower and
the terms and conditions by which Licensor shall reserve or license such tower
space to Licensee.

                                   AGREEMENTS

In consideration of the mutual covenants benefiting the parties hereto, and for
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged and confessed, the parties hereto agree as follows:

1. DEFINITIONS. Capitalized terms defined in the body of this Agreement or in
the Schedules hereto are indexed by location on Appendix I hereto. Capitalized
terms used in this Agreement but not defined herein are defined in Appendix I.

2. PARTIES. Unless otherwise mutually agreed, the parties hereto agree that the
terms and conditions herein shall be binding upon and exclusive to each party
hereto and their respective Affiliates with respect to any license or lease of
space by Licensee or any of its Affiliates on any communications tower and/or
communications building or shelter then-owned or operated by Licensor or any of
its Affiliates ("Communication Tower(s)") entered into during the Term of this
Agreement. This Agreement shall not, unless Licensor specifically agrees
otherwise, be applicable to any communication tower, building or shelter which
is managed or marketed by Licensor, as agent or representative, on behalf of a
third party.

3. RESERVATION AND LICENSE OF TOWER SPACE.

         3.1 APPLICATION FOR CO-LOCATION/REQUESTS TO RESERVE OR LICENSE SPACE.
From time to time during the Term, Licensee may submit applications to Licensor
to request the reservation or licensing of tower space on any one or more of
Licensor's Communication Towers. An application to reserve or license any
particular Communication Tower shall be made by Licensee submitting two duly
completed counterparts of Schedule 1 (to apply to reserve co-location space) or
Schedule 2 (If the request is to license space), in each case, identifying the
tower space that Licensee desires to reserve or license. Licensee may submit
requests for multiple spaces at one time, and shall complete for each space two
original counterparts of Schedule 1 (to apply to reserve co-location space) or
Schedule 2 (if the request is to license space).

<Page>

                  (a) RESERVED SPACE. Within ten (10) Business Days after
receiving a completed reservation request in the form of Schedule 1 from
Licensee, Licensor will notify Licensee if the requested space is available and
the terms under which Licensor shall make such Communication Tower available to
Licensee by completing, executing and returning an original counterpart of the
Schedule 1 submitted by Licensee. The reservation of space requested by Licensee
on such Schedule 1 shall be deemed reserved exclusively for Licensee, in
accordance with the reservation terms detailed in such Schedule 1 as executed by
both parties, upon the complete execution of such Schedule 1 by both parties.
The Reservation Fee for such Reserved Space shall be payable to Licensor by
Licensee on or before the tenth (10th) Business Day following Licensee's receipt
of the Schedule 1 executed by Licensor. Tower space reserved in accordance with
the foregoing procedures is referred to herein as Reserved SPACE. Licensee may
not install any equipment on any Reserved Space unless and until it has been
converted to Licensed Space in accordance with Section 3.1(b). Licensee shall
have access to the relevant Communication Tower during the Reservation Period in
accordance with Section 8 herein to the extent reasonably necessary to
facilitate any reasonable due diligence that Licensee desires to perform. In the
event that Licensee elects to commission a Phase I environmental assessment
during the Reservation Period or Term, Licensee shall promptly provide a
photocopy of any such assessment to Licensor. It is expressly agreed that under
no circumstances shall Licensor be obligated to perform any remediation of
environmental concerns at any of the Communication Towers, subject to the
obligations of both parties hereto pursuant to Section 8.3.

                  (b) CONVERSION AND EXPIRATION OF RESERVED SPACE. Licensee may
elect to convert Reserved Space into Licensed Space (as hereinafter defined) by
delivering to Licensor (a) within the Reservation Period for such Reserved Space
a signed and completed Schedule 2 indicating, among other things, a License
Commencement Date not later than the last day of the Reservation Period and (b)
together with such Schedule 2, the Initial License Fee for such space. Any
Schedule 2 conversion notice that is submitted without the required payment
shall be of no force or effect. Licensee acknowledges that it shall not be
entitled to any refund of any portion of any Reservation Fee if Licensee elects
to convert Reserved Space to Licensed Space prior to the expiration of the
Reservation Period. Any Reserved Space that has not been converted to Licensed
Space during the Reservation Period and otherwise in accordance with this
Section 3.1(b) shall, upon expiration of the Reservation Period, expire and
thereafter Licensor shall be free to reserve or license such space to any other

with any of Licensor's or other licensee's building systems, or with any
pre-existing licensee's or other tower space user's use of such tower. Licensee
shall ensure, and Licensee's use of any Tower Facilities shall be subject to its
ability to ensure, that operation of all of its equipment is conducted in a
manner that does not interfere with Licensor's lighting system located on any of
the Communication Towers or, in the event that Licensee's equipment is installed
on the rooftop of a building, with equipment of any kind used by building
tenants. Upon notice, Licensee shall at its expense take all actions necessary
to eliminate such interference and shall immediately cease operations if
requested by Licensor until the interference is eliminated. If Licensee does

                                       8
<Page>

not immediately cease any interfering operation, Licensor shall have the right,
in addition to any other rights that it may have, to enjoin such interference or
to terminate this Agreement. Subsequent to a written request by Licensor, in
Licensor's sole discretion, each Licensee transmitter shall have a circulator
and harmonic filter installed between the transmitter output and antenna
feedline. Also, Licensor may, at its option, require Licensee to supply
additional radio frequency interference (RFI) limiting equipment for
installation on the equipment of such person whose equipment is experiencing
such interference.

                  (b) Licensee acknowledges and agrees that Licensor will from
time to time market and license to third parties space on the same tower and in
the same tower facilities (including equipment structures) as are licensed to
Licensee; provided that, Licensor agrees to cause any persons that are installed
or modified subsequent to the Commencement Date of the relevant License, on any
tower or other Tower Facilities after Licensor enters into a License with
Licensee with respect to such same tower or Tower Facilities not to interfere
with the operation of Licensee's equipment approved of by Licensor as it exists
at the time Licensor enters into a license agreement with such other person. In
the event Licensee experiences interference caused by other licensees, Licensee
shall notify Licensor of such interference and if Licensor is unable to
eliminate the interference, or reduce it to a level acceptable to Licensee,
within a period of thirty (30) days, then Licensee may terminate that particular
License with written notice to Licensor.

         8.7 LABELING AND IDENTIFICATION. Licensee shall identify its equipment
and equipment cabinets (unless such cabinet is located in a building owned by
Licensee) by labels provided by Licensor (or, if not provided by Licensor,
labels provided by Licensee and designed for such purpose) and shall permanently
identify its coaxial cable at the top and bottom. FAILURE BY LICENSEE TO SO
IDENTIFY ITS EQUIPMENT MAY CAUSE AN INTERRUPTION IN SERVICE OF LICENSEE'S
OPERATION AND SHALL CONSTITUTE A DEFAULT OF THIS AGREEMENT.

PARTIES.

         9.6 SURVIVAL. The provisions of this Section 9 shall survive the

                  (a) In the event that any Communication Tower is destroyed or
damaged by fire, lightning, windstorm, flood, earthquake, explosion, collapse,
aircraft or other vehicle damage or other casualty, Licensor shall, unless it
shall elect to terminate the term of this Agreement and the related Schedule
with respect to the affected Communication Tower as hereinafter provided,
promptly reconstruct or repair the Communication Tower to substantially the same
condition as existed before the destruction or damage and upon completion give
possession to Licensee of substantially the same space licensed under the
affected Schedule. If the Communication Tower Is In need of such repair or is so
damaged by fire, lightning, windstorm, flood, earthquake, explosion, aircraft or
other vehicle damage, collapse or other casualty that reconstruction or repair
cannot reasonably be undertaken without dismantling Licensee's Facilities, then
Licensor may, upon giving written notice to Licensee, remove any Licensee's
Facilities and interrupt the signal activity of Licensee but will use reasonable
efforts to have Licensee's Facilities replaced as soon as reasonably possible.
Licensee will be afforded the right, at Licensee's sole cost and expense, to
install temporary facilities pending repairs, provided such temporary facilities

<Page>

space, if available, on the Communication Tower during such reconstruction/
repair period. If Licensor elects not to restore the Communication Tower within
six month's from the date of any casualty, Licensor may, by notice to Licensee,
terminate the term of this Agreement and the related Schedule only with respect
to the affected Communication Tower on the date (not less than thirty day
thereafter) set forth in such notice. Should Licensor not substantially restore
or replace the Communication Tower in a fashion sufficient to allow Licensee to
replace Licensee's Facilities thereon within six (6) months of the date of
casualty provided that such 6 month period shall be automatically extended for
so long as Licensor has commenced and diligently continues to restore or replace
such Communication Tower, then Licensee, upon thirty (30) days' written notice
to Licensor may, at its option, terminate the term of this Agreement and the
related Schedule with respect to the affected Communication Tower.

                  (b) Licensor shall be entitled to terminate the term of this
Agreement and the related Schedule with respect to any particular Communication
Tower if all or any part of such Communication Tower is acquired, transferred,
condemned or taken pursuant to any eminent domain proceeding if as a result any
of such event, Licensor has determined not to continue to operate the
Communication Tower. Irrespective of the form in which recovery may be had by
law, all nights to damages or compensation shall belong to Licensor in all
cases. Licensee hereby grants to Licensor all of Licensee's rights to such
damages and covenants to deliver such further assignments thereof as Licensor
may from time to time request. Nothing contained herein shall be construed to
prevent Licensee from prosecuting in any eminent domain proceedings a claim for
relocation expenses, provided that such action shall not affect the amount of
compensation otherwise recoverable by Licensor from the taking authority.

                  (c) The License Fee with respect to the affected Communication
Tower shall be abated during any period that the Communication Tower has not
been restored following an event described in clauses (a) or (b) above so as to

of any License, all permanent alterations, installations, changes, replacements,
additions or improvements that (a) have been made by Licensee to the related
Tower Facilities and (b) cannot be removed without material damage to the
remainder of such Tower Facilities, shall be deemed a part of such Tower
Facilities and the same shall not be removed.

         11.3 LICENSEE'S PROPERTY. Upon the termination or expiration of any
License and so long as Licensee is not in Default hereunder, Licensee may remove
all property owned by Licensee so long as the removal thereof would not cause
material damages to property not owned by Licensee and shall repair any damage
caused to the Tower Facilities due to the removal of such property at Licensee's
expense. Licensee shall remove such property to one (1) foot below grade, and
such removal shall be performed by a qualified steeplejack, tower climber
