     RE:  $225 MILLION  SENIOR  SECURED  CREDIT  FACILITY  FOR HORIZON  PERSONAL
          COMMUNICATIONS, INC.

Gentlemen:

         We  understand  that  Horizon   Personal   Communications,   Inc.  (the
"Borrower")  intends  to  finance  the  direct  costs  of the  construction  and
operation  of a  regional  digital  wireless  telecommunications  network on the
Sprint PCS system (collectively,  the "Build-out").  We also understand that the
Borrower will enter into a Credit Agreement (the "Bank Credit Facility") for the
purposes of financing the Build-out having  substantially the terms set forth on
the summary of terms and  conditions  attached  hereto (the "Term  Sheet")  with
certain financial  institutions (the "Lenders") for an aggregate amount of up to
$225  million  which shall be in the form of a term loan and a revolving  credit
facility.  The Build-out and the transaction described in the foregoing sentence
are hereinafter referred to collectively as the "Transactions."

         Based upon and subject to the foregoing and to the terms and conditions
set forth below and in the Term Sheet, First Union National Bank ("First Union")
is pleased to confirm  its  commitment  (the  "Commitment")  to provide the Bank
Credit  Facility to the Borrower.  First Union's  obligation to provide the Bank
Credit  Facility  pursuant to this  Commitment is subject to (i) the  Borrower's
written  acceptance  of a letter from First  Union to the  Borrower of even date
herewith  (the "Fee  Letter")  pursuant to which the  Borrower  agrees to pay to
First Union  certain fees in  connection  with the Bank Credit  Facility as more
particularly  set forth  therein,  (ii) the  completion  of a definitive  credit
agreement  and related  documentation  for the Bank Credit  Facility in form and
substance  satisfactory to First Union,  (iii)  completion of all  documentation
relating to the  Build-out  (including,  without  limitation,  all contracts and

                                       1
<PAGE>

other  documentation),  in form and substance  satisfactory to First Union, (iv)
compliance  with all applicable laws and  regulations  (including  compliance of
this  Commitment  and the  transactions  described  herein  with all  applicable
federal banking laws,  rules and  regulations),  (v) the  determination of First
Union  and  FUSI (as  defined  below)  that,  prior to and  during  the  primary
syndication  of the Bank Credit  Facility,  there  shall have been no  competing
issuance of debt  (excluding,  for purposes  hereof,  the issuance of high yield
indebtedness  in an aggregate  amount of up to  $125,000,000  in net  proceeds),
securities  (excluding,  for purposes hereof, the initial public offering of the
common  stock of  Horizon  PCS,  Inc.  in an  aggregate  amount of not less than
$100,000,000  in net  proceeds) or  commercial  bank  facilities of the Borrower
being offered,  placed or arranged,  without the prior written  consent of First
Union and FUSI (vi) the  completion  by First Union of its legal,  financial and
business due  diligence in form and  substance  satisfactory  to First Union and
(vii) the satisfaction of all other  conditions  described  herein,  in the Term
Sheet  and in such  definitive  credit  documentation.  Further,  First  Union's
Commitment  is  subject  to there  not  having  occurred  any  material  adverse
disruption or other change in the financial, banking or capital markets that has
had or could  have a  material  adverse  effect on the  syndication  of the Bank
Credit  Facility.  In addition,  whether before or after the closing of the Bank
Credit  Facility,  First Union shall be entitled,  after  consultation  with the
Borrower,  to change the pricing  (provided,  however that it is agreed that the
applicable  percentages  referred to in the Term Sheet will not be  increased by
more than 2.0% above the rate stated therein if First Union shall have reached a
hold  level of  $100,000,000  or less),  structure  or terms of the Bank  Credit
Facility  (including,   without  limitation,   the  individual  amounts  of  the
facilities  but not the aggregate  amount of the Bank Credit  Facility) if First
Union determines that such changes are advisable in order to ensure a successful
pre-closing or  post-closing  syndication or an optimal credit  structure of the
Bank  Credit  Facility,  such right to  continue  until the  completion  of such
syndication notwithstanding the termination of the Commitment.

         It is agreed that First Union will act as the sole administrative agent
(the  "Administrative  Agent")  for any  other  Lenders  under  the Bank  Credit
Facility.  First Union,  through its  affiliate,  First Union  Securities,  Inc.
("FUSI" or the  "Arranger"),  will also serve as sole manager of the syndication
effort. In connection with such syndication effort,  First Union will manage all
aspects of the syndication,  including without limitation making decisions as to
the  selection  and  number  of  institutions  to be  approached  and when  such
institutions  will be  approached,  when  commitments  will be  accepted,  which
institutions  will  participate,  the allocations of commitments among syndicate
Lenders and the amount and distribution of fees payable to syndicate Lenders. As
a part of this process, First Union will consult with the Borrower regarding the
selection and number of institutions to be approached.

         First Union  reserves  the right,  prior to or after the  execution  of
definitive  documentation with respect to the Bank Credit Facility,  and as part
of any  syndication  thereof or  otherwise,  to arrange for the  assignment of a
portion of this  Commitment,  in accordance  with the Term Sheet, to one or more

                                       2
<PAGE>

mutually acceptable financial institutions that will become Lenders and be party
to such  definitive  documentation.  In addition,  in  connection  with any such
syndication,  the Borrower  acknowledges that First Union may allocate a portion
of the fees payable  under the Fee Letter to such other  Lenders.  It is agreed,
however,  that no  Lender  will  receive  compensation  from or on behalf of the
Borrower  outside the terms  contained  herein and in the Fee Letter in order to
obtain its commitment to participate in the Bank Credit Facility.

         The  Borrower  understands  that First Union  intends to  commence  the
syndication  efforts  immediately and intends to complete such syndication prior
to closing. In connection  therewith,  the Borrower agrees to assist First Union
in promptly completing a mutually satisfactory syndication. The syndication will
be  accomplished  by a variety  of means  including  direct  contact  during the
syndication  between senior management of the Borrower and First Union and their
respective affiliates and advisors. First Union reserves the right to engage the
services of FUSI and other of its  affiliates in  furnishing  the services to be
performed by First Union as contemplated  herein and to allocate (in whole or in
part) to any such affiliates any fees payable to it in such manner as it and its
affiliates may agree in their sole  discretion.  The Borrower  agrees that First
Union may share with any of its affiliates and advisors any information  related
to the Transactions or any other matter  contemplated  hereby, on a confidential
basis.

         The  Borrower  agrees  to afford  First  Union  and its  affiliates  an
opportunity to offer proposals to provide, arrange, underwrite or administer (i)
any interest  rate caps,  currency  swaps or other  hedging  transactions  to be
entered into by the Borrower or any of its affiliates, (ii) any cash management,
funds transfer, trade, corporate trust and securities services to be obtained by
the  Borrower or any of its  affiliates  and (iii) any public or private debt or
equity  instruments  or  securities  to be issued by the  Borrower or any of its
affiliates.

         You hereby  represent,  warrant and covenant that (i) all  information,
other than the Projections  (as defined  below),  which has been or is hereafter
made   available  to  First  Union  or  the  Lenders  by  you  or  any  of  your
representatives  in  connection  with  the  transactions   contemplated   hereby
("Information") is and will be complete and correct in all material respects and
does not and will not contain any untrue statement of a material fact or omit to
state a material fact  necessary to make the  statements  contained  therein not
misleading  and (ii) all financial  projections  concerning the Borrower and its
subsidiaries  that have been or are hereafter  made  available to First Union or
the Lenders by you or any of your  representatives (the "Projections") have been
or will be prepared in good faith based upon reasonable  assumptions.  You agree
to furnish us with such Information and Projections as we may reasonably request
and to supplement the Information  and the  Projections  from time to time until
the closing  date for the Bank Credit  Facility so that the  representation  and
warranty in the  preceding  sentence is correct on such date.  In arranging  and
syndicating  the Bank Credit  Facility  First Union will be using and relying on
the Information and the Projections without independent verification thereof.

                                       3

         The Borrower agrees to reimburse First Union, FUSI and their affiliates
for  all  of  their  reasonable  fees  and  out-of-pocket   expenses  (including
reasonable  attorneys'  fees  and  expenses)  incurred  in  connection  with the
transactions  described  herein.  The Borrower also agrees to indemnify and hold
harmless First Union, FUSI and their affiliates and their respective  directors,
officers,  employees and agents (collectively,  the "Indemnified  Parties") from
and against any and all actions,  suits, losses, claims and liabilities to third
parties  unaffiliated with the Indemnified Parties of any kind or nature,  joint
or several, to which such Indemnified Parties may become subject,  related to or
arising out of any of the transactions  contemplated  herein,  including without
limitation the execution of definitive credit documentation, the syndication and
closing of the Bank Credit  Facility and the closing of the other  Transactions,
and will  reimburse the  Indemnified  Parties for all  reasonable  out-of-pocket
expenses (including  reasonable  attorneys' fees and expenses) on demand as they
are  incurred in  connection  with the  investigation  of,  preparation  for, or
defense of any pending or threatened  claim or any action or proceeding  arising
therefrom;  provided,  that  no  Indemnified  Party  shall  have  any  right  to
indemnification  for any of the foregoing to the extent resulting primarily from
the gross negligence or willful  misconduct of any Indemnified Party or from any
material breach hereof. This Commitment is addressed solely to the Borrower, and
neither  First Union and FUSI, on the one hand,  nor the Borrower,  on the other
hand,  shall be liable to the other or any other  person  for any  consequential
damages  that  may be  alleged  as a  result  of this  Commitment  or any of the
transactions  referred  to  herein.  In the event  that the  closing of the Bank
Credit Facility fails to occur for any reason,  the provisions of this paragraph
shall survive any termination of this Commitment.

         Until such time as the Borrower has accepted this Commitment in writing
as provided  below,  the Borrower is not  authorized  to show or circulate  this
Commitment  or the Term Sheet,  or disclose the contents  thereof,  to any other
person or entity (other than to its directors,  officers and legal and financial
counsel;  provided  that (i) each of such persons shall agree to be bound by the
confidentiality  provisions hereof and (ii) the Borrower shall be liable for any
breach of such confidentiality  provisions by any such person), except as may be
required by law or applicable judicial process.

         This Commitment  shall  terminate at 5:00 p.m. on July 7, 2000,  unless
such  Commitment  is accepted by the Borrower in writing prior to such time and,
if accepted prior to such time, shall expire at the earlier of the occurrence of
any event that has, or could be expected to have, a material  adverse  effect on
the  business,  properties,  prospects,  operations  or condition  (financial or
otherwise)  of the  Borrower,  and (iv) 5:00 p.m.  on August  15,  2000,  if the
closing of the Bank Credit Facility shall not have occurred by such time.

         This  Commitment  and the Fee Letter shall be governed by and construed
in  accordance  with the  internal  laws of the  state of  North  Carolina,  and
together  constitute the entire  agreement  between the parties  relating to the
subject matter hereof and thereof and supersede any previous agreement,  written
or oral,  between the parties  with  respect to the  subject  matter  hereof and
thereof.  This Commitment  supersedes any prior or contemporaneous  agreement or

                                       4

understanding  between any parties  hereto  with  respect to the subject  matter
hereof. This Commitment may not be assigned without the prior written consent of
First Union.

         If the Borrower is in  agreement  with the  foregoing,  please sign the
enclosed copy of this Commitment and return it to First Union and FUSI, together
with an executed  copy of the Fee Letter and payment of that  portion of the any

the  request  of the  disclosing  Party,  the  receiving  Party  will  furnish a
certificate of an officer of the receiving  Party  certifying  that  Proprietary
Information  not  returned  to  disclosing  Party  has been  destroyed.  For the
purposes hereof, Proprietary Information does not include information which:

          (i) has been or may in the future be published or is now or may in the

     restriction of the third party's right to disseminate  the  information and

     has  received  written  notice  from the  receiving  Party that it does not
     desire to receive further Proprietary Information; or

          (vi) is obligated  to be produced  under order of a court of competent
     jurisdiction or other similar requirement of a Governmental Entity, so long

in the event of a breach or threatened breach of this Contract, without limiting
any other rights and remedies  specified  herein,  an  injunction  may be sought
against the Party who has breached or  threatened to breach this Section 6. Each
Party  represents and warrants that it has the right to disclose all Proprietary
Information which it has disclosed to the other Party pursuant to this Contract,
and each Party agrees to indemnify  and hold  harmless the other from all claims
by a third  party  related to the  wrongful  disclosure  of such  third  party's
Proprietary  Information.  Otherwise,  neither Party makes any representation or
warranty, express or implied, with respect to any Proprietary Information.
