                            CONFIDENTIAL INFORMATION

     Section 3. 1. Maintenance of Confidentiality. Each of Licensor and Licensee
and their  respective  Controlled  Related  Parties (each a "Restricted  Party")
shall cause their respective  officers and directors (in their capacity as such)
to, and shall take all reasonable measures to cause their respective  employees,
attorneys, accountants, consultants and other agents and advisors (collectively,
and together with their  respective  officers and directors,  "Agents") to, keep
secret  and  maintain  in  confidence  the  terms  of  this  agreement  and  all
confidential  and  proprietary  information  and data of the other  party or its
Related  Parties  disclosed  to it  (in  each  case,  a  "Receiving  Party")  in
connection  with the  performance of its  obligations  under this agreement (the
"Confidential  Information")  and shall not,  and shall cause  their  respective
officers and directors not to, and shall take all  reasonable  measures to cause
their respective other Agents not to, disclose  Confidential  Information to any
Person  other than the  parties,  their  Controlled  Related  Parties  and their
respective  Agents that need to know such Confidential  Information.  Each party
further  agrees  that it  shall  not use the  Confidential  Information  for any
purpose other than determining and performing its obligations and exercising its
rights  under this  agreement.  Each party  shall take all  reasonable  measures
necessary to prevent any unauthorized disclosure of the Confidential Information
by any of their respective Controlled Related Parties or any of their respective
Agents.  The  measures  taken  by a  Restricted  Party to  protect  Confidential
Information shall be not deemed  unreasonable if the measures taken are at least
as  strong  as the  measures  taken  by the  disclosing  party to  protect  such
Confidential Information.

     Section  3.2.  Permitted  Disclosures.  Nothing  herein  shall  prevent any
Restricted  Party or its Agents  from  using,  disclosing,  or  authorizing  the
disclosure of Confidential Information it receives and which:

     (i)  has been published or is in the public domain,  or which  subsequently
          comes into the public domain, through no fault of the receiving party;

     (ii) prior  to  receipt   hereunder  was  property  within  the  legitimate
          possession of the Receiving Party or,  subsequent to receipt hereunder
          is lawfully  received from a third party having rights therein without
          restriction of the third party's right to disseminate the Confidential
          Information and without notice of any restriction  against its further


                                       3
<PAGE>

          disclosure.

     (iii)is independently  developed by the Receiving Party through Persons who
          have not had, either directly or indirectly, access to or knowledge of
          such Confidential Information;

     (iv) is disclosed  to a third party with the written  approval of the party
          originally   disclosing   such   information,   provided   that   such
          Confidential   Information   shall  cease  to  be   confidential   and
          proprietary  information  covered by this agreement only to the extent
          of the disclosure so consented to;

     (v)  subject to the Receiving Party's compliance with Section 3.4 below, is
          required  to  be  produced   under  order  of  a  court  of  competent
          jurisdiction or other similar  requirements of a governmental  agency,
          provided that such Confidential Information to the extent covered by a
          protective  order or its  equivalent  shall  otherwise  continue to be
          Confidential  Information required to be held confidential for purpose
          of this agreement; or

     (vi) subject to the Receiving Party's compliance with Section 3.4 below, is
          required to be  disclosed  by  applicable  Law or a stock  exchange or
          association  on which such Receiving  Party's  securities (or those of
          its Related Party) are listed.

     Section 3.3. Financial  Institutions.  Notwithstanding  this Article 3, any
party may provide  Confidential  Information  to any  financial  institution  in
connection with borrowings from such financial  institution by such party or any
of its Controlled Related Parties,  so long as prior to any such disclosure such
financial  institution  executes  a  confidentiality   agreement  that  provides
protection  substantially  equivalent to the protection  provided the parties in
this Article 3.

     Section 3.4.  Procedures.  In the event that any  Receiving  Party (i) must
disclose Confidential  Information in order to comply with applicable Law or the
requirements of a stock exchange or association on which such Receiving  Party's
securities  or those of its Related  Parties are listed or (ii) becomes  legally
compelled  (by oral  questions,  interrogatories,  requests for  information  or
documents,  subpoenas,  civil investigative demand or otherwise) to disclose any
Confidential Information, the Receiving Party shall provide the disclosing party
with prompt  written  notice so that in the case of clause (i),  the  disclosing
party can work with the Receiving  Party to limit the disclosure to the greatest
extent possible consistent with legal obligations or in the case of clause (ii),
the disclosing party may seek a protective order or other appropriate  remedy or
waive compliance with the provisions of this agreement.  In the case of a clause
(ii),  (A) if the  disclosing  party is unable to obtain a  protective  order or
other appropriate  remedy, or if the disclosing party so directs,  the Receiving
Party  shall,  and shall  cause its  employees  to,  exercise  all  commercially
reasonable  efforts to obtain a protective order or other appropriate  remedy at
the  disclosing  party's  reasonable  expense,  and (B)  failing  the entry of a
protective order or other  appropriate  remedy or receipt of a waiver hereunder,
the  Receiving  Party  shall  furnish  only  that  portion  of the  Confidential
Information which it is advised by opinion of its counsel is legally required to


                                       4
<PAGE>

be furnished and shall exercise all  commercially  reasonable  efforts to obtain
reliable   assurance  that   confidential   treatment  shall  be  accorded  such
Confidential Information, it being understood that such reasonable efforts shall
be  at  the  cost  and  expense  of  the  disclosing  party  whose  Confidential
Information has been sought.

     Section 3.5. Survival.  The obligations under this Article 3 shall survive,
as to any party,  until two (2) years  following the date of termination of this
agreement  and,  as to any  Controlled  Related  Party  of a  party,  until  two
(2).years  following the earlier to occur of (A) the date that such Person is no
longer a Controlled Related Party of a party, or (B) the date of the termination
of this agreement;  provided that such obligations  shall continue  indefinitely
with respect to any trade secret or similar  information which is proprietary to
a party  or its  Controlled  Related  Parties  and  provides  such  party or its
Controlled Related Parties with an advantage over its competitors.

and warrants to the other party as follows:

     (a)  Due Incorporation or Formation, Authorization of Agreement. Such party
          is a corporation  duly  organized,  a limited  liability  company duly
          organized or a  partnership  duly  formed,  validly  existing  and, if
          applicable, in good standing under the laws of the jurisdiction of its

          contemplated  hereby.  Such party is duly  licensed or qualified to do
          business  and,  if  applicable,  is in  good  standing  in each of the
          jurisdictions  in which the  failure to be so  licensed  or  qualified
          would have a material adverse effect on its financial condition or its
          ability  to  perform  its  obligations  hereunder.  Such party has the
          corporate,  company or partnership  power and authority to execute and
          deliver this  agreement and to perform its  obligations  hereunder and
          the  execution,  delivery and  performance of this agreement have been

          hereto,  this  agreement  constitutes  the  legal,  valid and  binding
          obligation of such party enforceable  against such party in accordance
          with its terms,  subject  as to  enforceability  to limits  imposed by
          bankruptcy,  insolvency or similar laws  affecting  creditors'  rights
          generally and the availability of equitable remedies.

     (b)  No Conflict  with  Restrictions;  No Default.  Neither the  execution,
          delivery and  performance  of this agreement nor the  consummation  by
          such party of the transactions  contemplated  hereby (i) will conflict
          with, violate or result in a breach of any of the terms, conditions or
          provisions of any law, regulation,  order, writ,  injunction,  decree,
          determination  or award of any  court,  any  governmental  department,
          board,  agency  or  instrumentality,   domestic  or  foreign,  or  any
          arbitrator,  applicable to such party or any of its Controlled Related
          Parties,  (ii) will conflict with,  violate,  result in a breach of or
          constitute a default under any of the terms,  conditions or provisions
          of  the  articles  of  incorporation,   articles  of  organization  or
          certificate  of  formation,  bylaws,  operating  agreement  or limited
          liability company agreement, or partnership agreement of such party or
          any of its Controlled  Related Parties or of any material agreement or
          instrument  to  which  such  party  or any of its  Controlled  Related
          Parties  is a party or by which  such  party or any of its  Controlled
          Related  Parties  is or may be bound or to which  any of its  material
          properties  or  assets  is  subject  (other  than any  such  conflict,
          violation, breach or default that has been validly and unconditionally
          waived),  (iii) will conflict  with,  violate,  result in a breach of,
          constitute a default  under  (whether  with notice or lapse of time or
          both),  accelerate  or  permit  the  acceleration  of the  performance
          required  by,  give to  others  any  material  interests  or rights or
          require any consent,  authorization  or approval  under any indenture,

          its  Controlled  Related  Parties is a party or by which such party or
          any of its Controlled Related Parties is or may be bound, or (iv) will
          result  in the  creation  or  imposition  of any lien  upon any of the
          material  properties or assets of such party or any of its  Controlled
          Related  Parties,  which in any such case could reasonably be expected
          to materially  impair such party's  ability to perform its obligations
          under  this  agreement  or to have a  material  adverse  effect on the
          consolidated financial condition of each party or its Parent.

     (c)  Governmental Authorizations.  Any registration,  declaration or filing
          with, or consent, approval,  license, permit or other authorization or
          order by,  any  governmental  or  regulatory  authority,  domestic  or
          foreign,  that is required to be obtained by such party in  connection
          with the valid execution, delivery, acceptance and performance by such
          party under this  agreement or the  consummation  by such party of any
          transaction contemplated hereby has been completed,  made or obtained,
          as the case may be.

     (d)  Litigation. There are no actions, suits, proceedings or investigations
          pending  or, to the  knowledge  of such party,  threatened  against or
          affecting such party or any of its Controlled  Related  Parties or any

<PAGE>

          of their properties, assets or businesses in any court or before or by
          any  governmental   department,   board,  agency  or  instrumentality,
          domestic or foreign,  or any  arbitrator  which  could,  if  adversely
          determined  (or,  in the case of an  investigation  could  lead to any
          action,  suit or  proceeding,  which if adversely  determined  could),
          reasonably  be expected to materially  impair such party's  ability to
          perform its  obligations  under this  agreement  or to have a material
          adverse effect on the consolidated  financial  condition of such party
          or its parent; and such party or any of its Controlled Related Parties
          has not received any currently  effective  notice of any default,  and
          such party or any of its Controlled Related Parties is not in default,
          under  any  applicable  order,  writ,   injunction,   decree,  permit,
          determination  or award of any  court,  any  governmental  department,
          board,  agency  or  instrumentality,   domestic  or  foreign,  or  any
          arbitrator,  which default could  reasonably be expected to materially
          impair  such  party's  ability to perform its  obligations  under this

("Bright MSA") dated as of the day of October, 1999 ;

     WHEREAS, SBA and Lessee both wish to modify the Horizon MSA and Bright MSA.

     NOW  THEREFORE,  for  good  and  valuable  consideration  the  receipt  and
sufficiency of which are hereby acknowledged,  SBA, Bright and Horizon do hereby
agree as follows:

     1.  Secured  Financing  Addendum.  SBA and Lessee  wish to modify  both the
Horizon MSA and Bright MSA to incorporate the following provisions:

          Financing.  Lessee  may,  upon  notice  to SBA,  mortgage  or  grant a
     security  interest in this MSA and the  Equipment,  and may assign this MSA
     and the Equipment to any such  mortgagees or holders of security  interests
     including their successors and assigns (hereinafter  collectively  referred
     to as "Secured Parties").  In such event, SBA shall execute such consent to
     leasehold  financing  as may  reasonably  be required  by Secured  Parties.
     Provided that SBA has been given  written  notice of the name and addresses
     of the Secured  Parties by Lessee,  SBA shall  notify  Lessee and  Lessee's
     Secured Parties simultaneously of any default by Lessee and to give Secured
     Parties the same right to cure any  default as Lessee  except that the cure
     period  for any  Secured  Party  shall not be less  than 10 days  after the
     receipt of the default notice. If a termination, disaffirmance or rejection
     of the MSA pursuant to any laws  (including  any  bankruptcy  or insolvency
     laws) by Lessee shall  occur,  or if SBA shall  terminate  this MSA for any
     reason,  SBA will give to the Secured Parties prompt notice thereof and SBA
     will give the Secured  Parties the right to enter upon the  Property or BTS
     site, as  applicable,  during a 30-day period  commencing  upon the Secured
     Party's  receipt of such notice for the purpose of removing any  Equipment.
     Upon written  request from Lessee,  SBA shall execute and deliver a written


                                       1

     instrument  in  recordable  form   acknowledging  the  assignment  and  the
     foregoing agreements of SBA.

     2.  Consent  to  Assignment.   Notwithstanding  anything  to  the  contrary
contained  in this MSA,  SBA shall have the right to assign this MSA and any SLA
to an Affiliate of SBA, and upon such assignment, SBA shall be released from any
and all obligations  under the assigned MSA or SLA,  provided that such assignee
assumes all of SBA's obligations under such assigned agreement in writing at the
time of the  assignment.  For  purposes  of this MSA,  "Affiliates"  shall  mean
companies which control are controlled by, or under common control with SBA. For
purposes of this MSA, the word "control"  shall mean the ownership,  directly or
indirectly,  of the power to direct or cause the direction of the management and
policies of an entity,  or the power to veto major policy  decisions of any such
entity,  whether  through the  ownership  of voting  securities,  by contract or
otherwise.

     3. No Other Modifications.  The Horizon MSA and the Bright MSA shall remain
the entire  agreement  and  understanding  of SBA and Lessee with respect to the
subject  matter  thereof  except as  modified  by this  Addendum,  and except as
specifically  altered and amended herein, the Horizon MSA and the Bright MSA are
hereby ratified and confirmed in all respects, are in full force and effect, and
have not otherwise been amended, modified, extended or renewed, whether verbally
or in writing.

     IN WITNESS WHEREOF,  SBA, Horizon and Bright have executed this Addendum as
of the date and year first above written.
