representative  of the Bright Holders in their capacity as Indemnifying  Persons
or Indemnified  Persons  hereunder.  The Bright Holders further  acknowledge and
agree  that  they  shall  be bound by any and all  actions  taken by the  Bright
Holders  Representative  in resolving  all disputes or other issues  between the
Bright Holders,  on the one hand, and Telcom,  Percom, and PCS Holdings,  on the
other hand,  pursuant to the  provisions of Article 8 hereof or otherwise  under
this Agreement.  Telcom, Percom, and PCS Holdings shall be entitled to rely upon
any   communication  or  writings  given  or  executed  by  the  Bright  Holders
Representative. All notices to be sent to the Bright Holders pursuant to Article
9 hereof  pursuant to this  Agreement  may be  addressed  to the Bright  Holders
Representative  and any  notice  so sent  shall be  deemed  notice to all of the
Bright Holders.

     7F. Access to  Information.  At all times before the Closing Date,  each of
Telcom,  PCS Holdings and Percom shall provide the Bright  Holders,  through the
Bright  Holders  Representative,  with  reasonable  access to those  properties,
files,  books,  records and other materials relating to Telcom, PCS Holdings and
Percom and their  businesses and the right to examine and inspect such materials
as the Bright Holders may deem appropriate (and make copies of the same).

     7G. Representations and Warranties,  Supplemental Information. From time to
time prior to the Closing,  each party shall promptly disclose in writing to the
other any matter hereafter arising which, if existing, occurring or known at the
Agreement  Date would have been  required to be  disclosed to the other or which
would render inaccurate any of the representations, warranties or statements set
forth herein.

     7H. Tax Free Transfers.  The parties intend that the  Contribution  will be
part of a  single  integrated  transaction  in  which  no  gain or loss  will be
recognized  pursuant to IRC Section  351,  and the parties  agree that they will
prepare  and file  their  Federal  and  state  income  tax  returns  in a manner
consistent  with such  characterization.  Further,  each of the  Bright  Holders
agrees to provide to PCS Holdings a statement  setting  forth the amount of such
Bright  Holders' tax basis in the Units so that PCS Holdings can  determine  its
tax basis in such Units in  accordance  with IRC Section 362. Each Bright Holder
agrees to file the information  required by Treasury  Regulation ss. 1.351-3 for
its Federal income tax return for the taxable year of the contribution,  and PCS
Holdings agrees to furnish to each Bright Holder information necessary to enable
each Bright  Holder to comply with the  information  reporting  requirements  of
Treasury Regulation ss. 1.351-3.

     7I.  Disclosure  Letter.  The parties hereto shall  supplement or amend the
Disclosure  Letter from time to time prior to the  Closing;  provided,  however,
that any such  supplement  or amendment  (which does not represent an immaterial
update of matters  arising in the ordinary  course of business) shall not affect
any rights that the parties may have under this Agreement,  whether  relating to
closing conditions, indemnification or otherwise.

                                       18


     7J. Limited  Transferability of Units in Bright PCS. Subject to the further
provisions  of this Section 7J, no Bright Holder will sell,  page,  hypothecate,
convey,  or  otherwise  transfer  any Unit to any  person or entity  before  the
Closing. Notwithstanding anything in this Agreement to the contrary, the parties
hereto  agree that Percom and each of the Bright  Holders may  transfer,  for no
consideration,  a limited  number  of the Units of Bright  PCS to one or more of
their key employees,  officers,  or directors (each such transferee a "Permitted
Transferee" and each such transaction a "Permitted Unit  Transfer"),  subject to
the following  terms and  conditions:

     (i) Each Permitted Unit Transfer must be  accomplished on or before May 19,
     2000 (the  "Permitted  Unit  Transfer  Period"),  and PCS Holdings  must be
     provided  prompt written  notice of each  Permitted  Unit  Transfer,  which
     notice  shall  include  the name and address of the  Permitted  Transferee,
     together with the number of Units transferred;

     (ii) Percom and each of the Bright  Holders may not  transfer  more than an
     aggregate of 10% of the Units owned by it to Permitted Transferees;

     (iii)  Percom  and  each of the  Bright  Holders  may make  Permitted  Unit
     Transfers  to  only  one  individual  for  each  500  Units  owned  by such
     transferor,  provided  that each Bright Holder shall be permitted to make a
     Permitted Unit Transfer to at least one (1) Permitted Transferee; and

     (iv) Each  Permitted  Transferee  must,  as a  condition  precedent  to the
     effectiveness  of  a  Permitted  Unit  Transfer,   execute  a  receipt  and
     acknowledgement  letter in form and substance  satisfactory to PCS Holdings
     and its counsel, evidencing each Permitted Transferee's acknowledgement and
     agreement  that  each  Unit  received  in  a  Permitted  Unit  Transfer  is
     specifically  subject to the terms and conditions of this Agreement and the
     Bright PCS Operating Agreement,  and that, by acceptance of a Unit received
     in a Permitted Unit Transfer,  the Permitted  Transferee agrees to be bound
     by,  and shall  perform  all of the  appropriate  obligations  under,  this
     Agreement and the Bright PCS Operating  Agreement with respect to the Units
     transferred to him or her pursuant to a Permitted Unit Transfer.

     The parties hereto also agree that the Bright Holders will,  immediately to
the Closing, assign to JSI Capital Advisors LLC, the Bright Holders' independent
financial  advisor  ("JSI")  140  Units.  Such  transfer,   if  accomplished  in
accordance with the foregoing, shall also be a "Permitted Unit Transfer" and JSI
shall also be a "Permitted  Transferee",  provided that (i) PCS Holdings must be
provided with prompt written notice of such transfer,  and (ii) JSI must execute
a receipt and  acknowledgement  letter as contemplated in Section 7J.(iv) above,
in form and substance reasonably satisfactory to PCS Holdings and its counsel.

     In addition, the parties further agree that ComNet, Inc. may distribute any
of  the  Units  owned  by it to  its  shareholders  before  the  Closing,  which
transaction,  if  accomplished,  shall be a "Permitted  Unit  Transfer"  and the
recipients of such Units shall be "Permitted Transferees", provided that (i) PCS
Holdings is provided prompt written notice of such transfers, and (ii) such


                                       19


recipients must execute a receipt and acknowledgement  letter as contemplated in
Section  7J.(iv) above,  in form and substance  reasonably  satisfactory  to PCS
Holdings and its counsel.

     The  parties  hereto  acknowledge  and  agree  that  Attachment  A to  this
Agreement  shall be updated as soon as  practicable  after the expiration of the
Permitted Unit Transfer Period,  and again immediately prior to the Closing,  to
appropriately  evidence  the  correct  ownership  of Units  and the  appropriate
disposition thereof pursuant to the terms and conditions of this Agreement.

     Percom and each of the Bright  Holders  hereby (a) approves  all  permitted
Unit Transfers made pursuant to this Section 7J, (b) waives any and all notices,
waiting periods, rights of first offer or refusal set forth in Section 11 of the
Bright PCS Operating Agreement, and (c) approves the admission of each Permitted
Transferee  as a Member (as defined in the Bright PCS  Operating  Agreement)  of
Bright PCS.

     7K. Continued  Applicability of Certain  Provisions of Bright PCS Operating
Agreement to Shares. Notwithstanding anything in this Agreement to the contrary,
each of the Bright  Holders  acknowledge  and agree  that,  from the date hereof
until the  earlier of (i) the  effectiveness  of a public  offering  of stock of
Horizon  PCS, or (ii)  December 31, 2000,  the  provisions  of Article 11 of the
Bright  PCS  Operating  Agreement,  which set forth  certain  restrictions  upon
transfer of the Units and which set forth  certain  rights of first refusal with
respect to any  contemplated  transfer of the Units,  shall be applicable to the
Shares received by the Bright  Holders,  such that such shares shall likewise be
subject  to certain  restrictions  upon  transfer,  and shall also be subject to
certain rights of first refusal.

     7L. Registration Rights Agreement. At the Closing,  Holdings and the Bright
Holders shall execute a Registration  Rights Agreement in the form of Attachment
D hereto.

     Section 8 Indemnification.

     8A.  Indemnification by Telcom,  Percom,  and PCS Holdings.  Subject to the
terms, conditions and limitations of this Section 8, the Telcom, Percom, and PCS
Holdings  jointly and severally  shall  indemnify  the Bright  Holders and their
respective officers, directors,  trustees, employees, agents and representatives
(the "Bright Holders  Indemnified  Parties") against,  and agree to hold each of
them harmless from, any and all Losses  incurred or suffered by them relating to
or arising out of or in  connection  with any of the  following (in each case so
long as notice of a claim for  indemnification  is made in good faith during the
survival period set forth in Section 9E):

     i. any breach of any representation or warranty made by Telcom,  Percom, or
     PCS Holdings in this Agreement; or

     ii. any breach,  inaccuracy,  or failure by Telcom, Percom, or PCS Holdings
     to perform any covenant or  obligation of Telcom,  Percom,  or PCS Holdings
     under this Agreement.

                                       20


     8B. Indemnification by the Bright Holders. Subject to the terms, conditions
and limitations of this Section 8, each Bright Holder shall severally  indemnify
Telcom,  Percom,  and PCS Holdings  and their  Affiliates  and their  respective
officers,  directors,  trustees,  employees,  agents  and  representatives  (the
"Telcom Indemnified  Parties") against,  and agree to hold each of them harmless
from, any and all Losses incurred or suffered by them relating to or arising out
of or in connection with any of the following (in each case so long as notice of
a claim for indemnification is made in good faith during the survival period set
forth in Section 9E):

     i. any breach of or any inaccuracy in any  representation  or warranty made
     by such Bright Holder in this Agreement;

     ii. any breach of or failure by such Bright  Holder to perform any covenant
     or obligation of it under this Agreement; or

     iii. any action taken by Bright Holders'  Representative  purporting to act
     in his  capacity  as such and any  claim  by any  person  that  the  Bright
     Holders' Representative acted outside his duties.


     8C. Claims. As soon as is reasonably  practicable after becoming aware of a
claim for  indemnification  under this  Agreement the  Indemnified  Person shall
promptly give notice to the Indemnifying Person of such claim and the amount the
Indemnified  Person  believes  it is  entitled  to  receive  hereunder  from the
Indemnifying Person; provided that the failure of the Indemnified Person to give
notice shall not relieve the Indemnifying  Person of its obligations  under this
Section 8, except to the extent (if any) that the Indemnifying Person shall have
been prejudiced  thereby.  If the Indemnifying Person does not object in writing
to such  indemnification  claim  within 30  calendar  days of  receiving  notice
thereof,  the Indemnified  Person shall be entitled to recover promptly from the
Indemnifying  Person the amount of such  claim,  and no later  objection  by the
Indemnifying  Person shall be permitted.  If the Indemnifying Person agrees that
it has an  indemnification  obligation  but objects  that it is obligated to pay
only a lesser amount,  the Indemnified  Person shall nevertheless be entitled to
recover  promptly  from the  Indemnifying  Person  the  lesser  amount,  without
prejudice to the Indemnified Person's claim for the difference.  Any claim under
this  Section 8 must be made on or prior to the end of the  survival  period set
forth  in  Section  9E.  No  claim  may  be  delivered  in  writing  against  an
Indemnifying  Person under this Section 8 until the aggregate amount of all such
claims equals at least $100,000 at which time the  Indemnifying  Person shall be
liable for all claims  including the initial  $100,000 in claims (the "Basket"),
and the maximum Losses (other than a breach of the  representations set forth in
Section 4C and 5C) which an Indemnifying  Person shall be obligated to pay under
the  provisions  hereof shall be limited to  $9,000,000  in the  aggregate  (the
"Cap");  provided,  however, that the Basket and the Cap shall not be applicable
to a breach of the  representations  and warranties set forth in Sections 4C.vi,
4C.vii, and 5C hereof.

     8D. Assumption of Defense. The Indemnifying Person may, at its own expense,
(a) participate in the defense of any claim,  suit, action or proceeding and (b)
upon notice to the Indemnified Person and the Indemnifying  Person's  delivering
to the Indemnified  Person a written  agreement that the  Indemnified  Person is
entitled to indemnification  pursuant to Section 8A or 8B for all Losses arising


                                       21


out of such claim,  suit,  action or  proceeding,  assume the  defense  thereof;
provided,  however,  that (i) the  Indemnifying  Person's  counsel is reasonably
satisfactory to the Indemnified  Person and (ii) the  Indemnifying  Person shall
thereafter  consult with the Indemnified  Person upon the  Indemnified  Person's
reasonable  request for such consultation from time to time with respect to such
claim,  suit,  action or  proceeding.  If the  Indemnifying  Person assumes such
defense,  the  Indemnified  Person  shall  have the right  (but not the duty) to
participate in the defense  thereof and to employ  counsel,  at its own expense,
separate from the counsel employed by the Indemnifying  Person. If, however, the
Indemnified Person reasonably  determines in its judgment that representation by
the  Indemnifying  Person's  counsel  of both the  Indemnifying  Person  and the
Indemnified Person would present such counsel with a conflict of interest,  then
such Indemnified Person may employ separate counsel to represent or defend it in
any such claim, action, suit or proceeding and the Indemnifying Person shall pay
the  fees  and  disbursements  of  such  separate  counsel.  Whether  or not the
Indemnifying  Person chooses to defend or prosecute any such claim, suit, action
or  proceeding,  all of the parties  hereto  shall  cooperate  in the defense or
prosecution thereof.

     8E.  Settlement or Compromise.  Any settlement or compromise made or caused
to be made by the Indemnified Person or the Indemnifying Person, as the case may
be, of any such claim,  suit,  action or  proceeding  of the kind referred to in
Section 8D shall also be binding upon the Indemnifying Person or the Indemnified
Person,  as the case may be, in the same manner as if a final judgment or decree
had been  entered  by a court of  competent  jurisdiction  in the amount of such
settlement or compromise; provided, however, that no obligation,  restriction or
Loss shall be imposed on the  Indemnified  Person as a result of such settlement
without  its prior  written  consent,  which  consent  will not be  unreasonably
withheld or delayed. The Indemnified Person will give the Indemnifying Person at
least 10 days' notice of any proposed  settlement  or  compromise  of any claim,
suit,  action or proceeding it is defending,  during which time the Indemnifying
Person may reject such proposed  settlement or  compromise;  provided,  however,
that from and after such rejection,  the Indemnifying  Person shall be obligated
to assume the defense of and full and complete  liability and responsibility for
such claim,  suit,  action or  proceeding  and any and all Losses in  connection
therewith  in  excess  of  the  amount  of  unindemnifiable   Losses  which  the
Indemnified  Person  would  have  been  obligated  to  pay  under  the  proposed
settlement or compromise.

     8F.  Failure  of  Indemnifying  Person  to  Act.  In  the  event  that  the
Indemnifying  Person  does not elect to assume the  defense of any claim,  suit,
action or proceeding, then any failure of the Indemnified Person to defend or to
participate in the defense of any such claim,  suit,  action or proceeding or to
cause the same to be done,  shall not  relieve  the  Indemnifying  Person of its
obligations hereunder.

     8G. No Set-Off.  The  indemnification  obligations of the parties hereunder
shall be limited as set forth  herein and no party  shall be entitled to set-off
such  indemnification  obligations or any other amounts against any amounts owed
to such party by any other party.

     8H. Exclusive Remedy.  The remedies provided for in this Article 8 shall be
the sole and exclusive  remedy for the  indemnified  parties with respect to any
claim  under this  Agreement,  except for  equitable  claims or claims  based on
fraud.

     Section 9 Miscellaneous.

                                       22


     9A. Transfer and Similar Taxes.  All sales,  use, stock,  stamp,  transfer,

Telcom,  Percom or the Bright Holders of property  described in Section 2 hereof
shall be paid by PCS Holdings.

     9B. Complete Agreement.  This Agreement  (including the Exhibits hereto, if
any, and the  Disclosure  Letter)  represents the entire  agreement  between the
parties hereto covering everything agreed upon or understood in this transaction
and all other prior agreements,  written or oral are merged into this Agreement.
There  are  no  oral  promises,  conditions,  representations,   understandings,
interpretations  or  terms  of any  kind as  conditions  or  inducements  to the
execution hereof in effect between the parties.

     9C. Authorized Signatories. The persons executing this Agreement for and on
behalf of the  parties  hereto  each  represent  that  they  have the  requisite
authority to bind the entities on whose behalf they are signing.

     9D.  Termination.  In the event that for any reason  the  Closing  does not
occur on or before August 31, 2000, then any party, if not then in breach of its
obligations under this Agreement, may terminate this Agreement by giving written
notice thereof to the other party;  provided,  however, that no such termination
shall  relieve  either  party of  liability  for any  breach of its  obligations
hereunder prior to such termination.

     9E. Survival of Representations,  Warranties, and Covenants.  Regardless of
any  investigation  made by any  party or on its  behalf,  all  representations,
warranties,  and covenants  contained  herein or made in writing by any party in
connection  herewith  shall survive the execution and delivery of this Agreement
and the consummation of the  transactions  contemplated  hereby,  until June 30,
2001 in the case of all matters other than the  representations  and  warranties
set forth in  Sections  4C and 5C hereof,  and  indefinitely  in the case of the
representations  and  warranties  set forth in Sections  4C.vi,  4C.vii,  and 5C
hereof.

     9F.  Successors  and  Assigns.  This  Agreement  may not be assigned by any
Bright  Holders,  other  than as  contemplated  in  Section  7J  hereof  or to a
wholly-owned  subsidiary  entity of such  Bright  Holder,  without  the  written
consent of Telcom, Percom, and PCS Holdings.  This Agreement may not be assigned
by Telcom,  Percom,  or PCS Holdings  without the consent of the Bright  Holders
Representative. Except as otherwise expressly provided herein, all covenants and
agreements  contained in this  Agreement  by or on behalf of the parties  hereto
shall bind and inure to the benefit of the respective  successors and assigns of
the parties hereto whether so expressed or not.

     9G. Severability. Whenever possible, each provision of this Agreement shall
be interpreted in such manner as to be effective and valid under applicable law,
but if any  provision of this  Agreement is held to be  prohibited by or invalid
under  applicable law, such provision shall be ineffective only to the extent of
such  prohibition  or  invalidity,  without  invalidating  the remainder of this
Agreement.

     9H. Counterparts.  This Agreement may be executed  simultaneously in two or
more counterparts, any one of which need not contain the signatures of more than
one party, but all such counterparts taken together shall constitute one and the
same Agreement.

                                       23


     9I. Descriptive Headings:  Interpretation. The descriptive headings of this
Agreement are inserted for  convenience  only and do not constitute a Section of
this  Agreement.  The use of the word  "including" in this Agreement shall be by
way of example  rather than by  limitation.

     9J.  Governing  Law.  This  Agreement  shall be governed by the laws of the
State  of  Delaware,  without  regard  to  conflicts  of  laws  principles.

     9K. Amendment. No change or addition shall be made to this Agreement except
by a written agreement executed by Telecom, Percom, PCS Holdings, and the Bright
Holders Representative.

                AMENDMENT TO CONTRIBUTION AND EXCHANGE AGREEMENT

     THIS  AMENDMENT is made as of May 19, 2000, by and among  HORIZON  PERSONAL
COMMUNICATIONS,  INC., an Ohio corporation ("Percom"),  HORIZON TELCOM, INC., an
Ohio corporation  ("Telcom"),  HORIZON PCS, INC., a Delaware  corporation  ("PCS
Holdings") and Lonnie Pedersen (the "Bright Holders Representative").

                               W I T N E S S E T H

     WHEREAS,   that   certain   Contribution   and  Exchange   Agreement   (the
"Contribution and Exchange  Agreement"),  dated May 4, 2000, was entered into by
and among Percom,  Telcom, PCS Holdings,  the Bright Holders  Representative and
certain  persons  listed on the  Attachment  to the  Contribution  and  Exchange
Agreement (collectively, the "Bright Holders"); and

     WHEREAS,  Section 9K of the Contribution and Exchange  Agreement allows the
Contribution  and  Exchange  Agreement  to be  amended  by a  written  amendment
executed by Percom, Telcom, PCS Holdings and the Bright Holders  Representative;
and

     WHEREAS,  the parties to the Contribution and Exchange  Agreement desire to
amend the Contribution and Exchange Agreement.

     NOW,  THEREFORE,  in consideration of mutual covenants contained herein and
for other good and valuable consideration,  the receipt and sufficiency of which
is hereby acknowledged, the parties hereto agree as follows:

     1. Terms used  herein but not  defined  herein  shall have the  meaning set
forth in the Contribution and Exchange Agreement.

     2. Section  7J(i) is hereby  deleted in its entirety and replaced  with the
following:

     "Percom  will  promptly   provide  written  notice  to  the  Bright  Holder
     Representative of its receipt of the Sprint PCS Consent ("Consent Notice").
     Each  Permitted Unit Transfer must be  accomplished  on or before the fifth
     business day after the receipt of the Consent  Notice by the Bright Holders
     Representative (the Permitted Unit Transfer Period"), and PCS Holdings must
     be provided  prompt written notice of each,  which notice shall include the
     name and address of the Permitted  Transferee,  together with the number of
     units transferred."

     3. Item 4C (d) of the Disclosure Letter is hereby deleted in its
entirety and replaced with the following:

     "In connection with the proposed grant by Sprint PCS of additional  markets
     to Percom in Pennsylvania, New York and New Jersey, Sprint PCS will receive
     a warrant to acquire  shares of the commons  stock of PCS  Holdings.  It is
     currently  contemplated  that,  in the event PCS Holdings  conducts an IPO,
     Sprint  PCS will  receive  a warrant  to  acquire  2,510,460  shares of PCS
     Holdings'  Class A Common Stock at a per share  exercise price equal to the



     price per share to the public in the IPO. If PCS Holdings does not close an
     IPO prior to July 31, 2003,  Sprint PCS will  receive  warrants to purchase
     shares of Class A Common  Stock equal to 3% of the shares of PCS  Holdings'
     common stock outstanding, on a fully diluted basis, as of July 31, 2003."

     4. Item 4C(e) of the Disclosure Letter is hereby deleted in its entirety.

     5. The Bright  Holders  Representative  acknowledges  and  agrees  that the
amendments/supplements  to the Disclosure Letter contained in paragraphs 3 and 4
above do not affect the Bright  Holders'  obligation  to close the  transactions
contemplated in the Agreement and that such amendments/supplements  shall not be
used as a reason by the Bright Holders or the Bright Holders  Representative  to
fail to close the transactions contemplated in the Agreement.

     6.  Section 9M is hereby  deleted in its  entirety  and  replaced  with the
following:

     "Expenses. Each party hereto will pay its own expenses (whether legal, tax,
     accounting,  financial  advice  or  otherwise)  in  connection  with  these
     transactions;  provided,  however, that PCS Holdings agrees to pay all such
     reasonable costs and expenses  (whether legal, tax,  accounting,  financial
     advice or otherwise)  actually  incurred by the Bright  Holders  (including
     without  limitation  the  amounts  paid to ComStock  Valuation  Advisors to
     perform  valuation  services  with respect to the Telcom  Shares),  up to a
     maximum amount of $100,000."

     7.  This  Amendment  may  be  executed   simultaneously   in  two  or  more
counterparts,  any one of which need not contain the signatures of more than one
party,  but all such  counterparts  taken together shall  constitute one and the
same Amendment.  In the event of any conflict between any term of this Amendment
and the terms of the Contribution and Exchange  Agreement,  this Amendment shall
prevail.  In all other respects,  the Contribution and Exchange  Agreement shall
remain in full force and effect.


                        [signatures on following page(s)]



     IN WITNESS WHEREOF,  the parties hereto have executed this Agreement on the
