                          LIMITED FORBEARANCE AGREEMENT

                  THIS LIMITED FORBEARANCE AGREEMENT (this "Agreement") is dated
as of November 16, 2001, among PINNACLE TOWERS INC., a Delaware corporation (the
"Borrower"), the Parent, each of their Subsidiaries (the Borrower, the Parent
and their Subsidiaries, each a "Loan Party" and collectively, the "Loan
Parties") the several Lenders (as such term is defined in the hereinafter
described Credit Agreement) parties to this Agreement, and BANK OF AMERICA,
N.A., as Administrative Agent for the Lenders (in such capacity, the
"Administrative Agent").

                                   RECITALS:

         A.       The Borrower, the Administrative Agent, and the several
Lenders parties thereto entered into that certain Fifth Amended and Restated
Credit Agreement, dated as of September 17, 1999 (as amended through the date
hereof and as may be further amended, modified, restated, supplemented, renewed,
extended, increased, rearranged and/or substituted from time to time, the
"Credit Agreement").

         B.       The Borrower has advised the Lenders that the Defaults and
Events of Default set forth on the attached Schedule I (the "Anticipated
Defaults") will exist and be continuing upon the Borrower's delivery of a
Compliance Certificate on November 14, 2001.

         C.       The Borrower has requested that the Lenders agree to forbear
from exercising certain rights available to them as a result of the Anticipated
Defaults by the Borrower, and the Lenders have agreed to do so on the terms set
forth herein.

         NOW, THEREFORE, in consideration of the premises and the covenants,
terms, conditions, representations and warranties herein contained, the parties
hereto agree hereby as follows:

         SECTION 1.        DEFINED TERMS. Capitalized terms used herein and not
otherwise defined herein shall have the meanings set forth in the Credit
Agreement.

         SECTION 2.        LIMITED FORBEARANCE. The Borrower has requested that
the Administrative Agent and the Lenders forbear from exercising the rights and
remedies available to them as a result of the Anticipated Defaults during the
period from the date hereof to and including December 12, 2001. The
Administrative Agent and the Lenders hereby agree to forbear from exercising the
rights and remedies available to them as a result of the Anticipated Defaults,
including the right to demand default interest under Section 2.08 of the Credit
Agreement, from the Effective Date (defined in Section 10(f) below) to and
including the Termination Date (as defined below), subject to the terms of this
Agreement and subject to the occurrence of no further Default or Event of
Default either pursuant to the Sections of the Credit Agreement subject to the
Anticipated Defaults or otherwise. Upon the earlier of (i) the occurrence of any
Default or Event of Default, other than the Anticipated Defaults, (ii) the
amendment and waiver of the Anticipated Defaults by the requisite Lenders under
the terms of the Credit Agreement, or (iii) December 12, 2001 (the "Termination
Date"), the Administrative


<PAGE>
 Agent's and the Lenders' agreement herein to forbear from exercising the rights
and remedies available to them as the result of the Anticipated Defaults shall
immediately terminate, and the Administrative Agent and the Lenders shall be
entitled immediately to exercise any and all rights and remedies available under
the Credit Agreement and any other Loan Paper, at law, in equity, or otherwise,
without notice, demand, presentment, notice of dishonor, notice of acceleration,
notice of intent to accelerate, protest, or other formalities of any kind, all
of which are hereby expressly waived by the Borrower. The Borrower and the
Lenders hereby acknowledge Borrower's anticipated noncompliance with the Credit
Agreement as a result of the Anticipated Defaults and acknowledge that this
Agreement constitutes notice thereof and waive any and all further notices with
respect thereto. The agreement of the Administrative Agent and the Lenders
herein shall not constitute a waiver of any Default or Event of Default
including without limitation the Anticipated Defaults. The Borrower hereby
acknowledges that, unless and until the Anticipated Defaults are waived by the
requisite number of Lenders in accordance with the Credit Agreement, the Lenders
shall have no commitment to make Revolver Advances or issue Letters of Credit or
otherwise advance any funds to the Borrower. Notwithstanding any provision in
the Credit Agreement or any other Loan Paper to the contrary, the parties hereto
expressly acknowledge and agree that, until the Termination Date, the
Administrative Agent may renew (but not increase) Letters of Credit in existence
as of the date hereof. Notwithstanding any provision in the Credit Agreement or
any other Loan Paper, the parties hereto expressly acknowledge and agree that,
any draw under any Letter of Credit during the term of this Agreement shall
immediately and automatically result in an obligation for the Borrower to
reimburse the Administrative Agent for any such draw (which reimbursement
obligation may not be paid by the Borrower with the proceeds of a Revolver
Advance). Failure of the Borrower to reimburse the Administrative Agent in
immediately available funds for any such draw within 2 business hours after
receipt of notice of such draw shall constitute an Event of Default hereunder
and under the Credit Agreement (such reimbursement to be effected by payment in
full from the cash collateral account described in Section 4(i) hereof or by
wire transfer of immediately available funds, or any combination of the
foregoing). The parties hereto expressly acknowledge and agree that the
agreement of the Borrower in the preceding two sentences does not affect or
abrogate any of the obligations of the Lenders to the Issuing Bank to
participate in any such draws under the Letter of Credit. The parties hereto
further expressly acknowledge and agree that the agreements of the
Administrative Agent and the Lenders herein shall not in any manner restrict or
impair any rights or remedies available to them with respect to any Persons
other than the Borrower and other Persons guaranteeing the Obligations or
providing collateral security therefor.

         SECTION 3.        OTHER AGREEMENTS. To induce the Administrative Agent
and Lenders to enter into this Agreement, the Borrowers hereby agree as follows:

         (A)      During the period from the Effective Date and continuing until
the Termination Date, the Applicable Margin shall be (i) with respect to
Advances outstanding under the Term Loan A and the Revolver Loan shall be 3.75%
per annum for LIBOR Advances and 2.75% per annum for Base Advances and (ii) with
respect to Advances under the Term Loan B, 4.00% per annum for LIBOR Advances
and 3.00% per annum for Base Advances, provided that, notwithstanding the
foregoing, if there exists a Default or Event of Default other than the
Anticipated Defaults, no LIBOR borrowings shall be available to the Borrower.
During the period from the Effective Date until the Termination Date, while
interest will accrue at the rates described above with respect to the Applicable
Margin, the Borrower will pay interest at the rates


                                      -2-
<PAGE>

per annum and at the times provided in the Credit Agreement. The aggregate
additional amount of interest owed hereunder as a result of the increase in
interest rate set forth in this Section 3(a), shall be due and payable on the
Termination Date.

Date, all notices to be provided to the Administrative Agent shall be provided

         (D)      On the Effective Date and continuing until the Termination
Date, Borrower will, and will cause each of the Parent and their Subsidiaries
(other than Subsidiaries organized under the Laws of the country other than the
United States), to grant a prior first perfected Lien on any of the assets of
the Borrower, the Parent or their Subsidiaries requested by the Administrative
Agent or the Majority Lenders for the benefit of the Administrative Agent and
the Lenders to secure the Obligations, (including, without limitation, all cash,

Subsidiaries), provided that, notwithstanding the foregoing, (i) no foreign
organized Subsidiary of the Parent or the Borrower will be required to


                                      -3-
<PAGE>

grant a Lien on any of its assets, (ii) with respect to any Capital Stock owned
by the Borrower, the Parent, any of their foreign organized Subsidiaries, such
pledge will be limited to 65% of the aggregate outstanding issued amount of
Capital Stock of such foreign organized Subsidiary, (iii) the Borrower will
pledge its interest in 65% of the Capital Stock of the Canada Sub, but such
pledge will be a second Lien, and (iv) the Borrower will use its best efforts to
grant a prior first perfected Lien on twenty additional leasehold mortgages (or
leasehold deeds of trust) requested by the Administrative Agent.

         SECTION 4.        PROCEEDS OF ASSET SALES. On the Effective Date and
continuing until the Termination Date, the Borrower shall use the Net Proceeds
of sales of assets or Properties by the Borrower, the Parent or any of their
Subsidiaries (which for purposes of this Agreement shall not exclude asset sales
in the ordinary course of business, but provided that no such sales of assets or
Properties by the Parent, the Borrower or any of their Subsidiaries shall be
permitted except as set forth in Section 5 hereof) as follows: (i) first, to
establish a $2,500,000 cash collateral account to secure the Obligations,
including but not limited to any letter of credit reimbursement obligations, in
accordance with the terms of a Restricted Cash Collateral Account Agreement
executed by the parties in the form attached hereto as Exhibit A, and (ii)
second, to establish a $200,000 retainer for the benefit of Special Counsel in
connection with the continued legal expenses and legal fees and the consulting
fees of Deloitte Consulting associated with the Loans. To the extent that the
Borrower consummates the sale of certain of the St. Louis, Missouri Collocation
Facilities or any other sales of assets and Properties by the Parent, the
Borrower and their Subsidiaries, the Net Proceeds shall be applied as described
above to the extent there has not already been an asset sale or there has been
an asset sale that did not generate funds adequate to fund the referenced
account and retainer. Any additional Net Proceeds from such sale of the St.
Louis, Missouri Collocation Facilities and all other Net Proceeds from all other
sales of assets and Properties by the Borrower, the Parent or any of their
Subsidiaries will be applied in the following order: (x) to immediately prepay
the scheduled amortization of the Obligations due on December 31, 2001, such
prepayment to be in an aggregate amount equal to $7,321,864.00 (each Lender
agrees that such prepayment application in the order of maturity is specifically
permitted by the Lenders hereunder), (y) to reimburse the Borrower for all
amounts paid by the Borrower between November 1, 2001 and November 15, 2001 for
the reimbursement of the Administrative Agent for its fees and expenses of
counsel and consultants in accordance with the terms of the Credit Agreement,
and (z) to the extent of any remaining Net Proceeds, to prepay the Revolver
Loan, the Term Loan A and the Term Loan B, ratably. Such prepayment amounts
under subsection (z) above shall be applied to installments due in the inverse
order of maturity with respect to Term Loan A and Term Loan B, and shall not
affect the scheduled reductions of the Commitment required by Section 2.11(b) of
the Credit Agreement. Notwithstanding the foregoing, if (A) the Borrower sells
the Collocation Facilities located in Beaumont, Texas in accordance with the
provisions of Section 5 below, (B) all preceding requirements of this Section 4
have been satisfied except subsection (z) above and (C) amounts in the cash
collateral account described in (i) above are not less than $2,500,000, the
Borrower may retain for its own use an amount equal to 20% of the Net Proceeds
of the sale of the Collocation Facilities located in Beaumont, Texas, and the
remaining 80% of such Net Proceeds must be applied in accordance with the terms
of subsection (z) above. Any prepayment amounts applied to the Revolver Loan in
accordance with this Section 4 shall permanently reduce the Commitment.

         SECTION 5.        PERMITTED ASSET SALES. On the Effective Date and
continuing until the Termination Date, so long as (a) there exists no Default or
Event of Default both before and after giving effect to such sale (except the
Anticipated Defaults), (b) the gross proceeds of each such sale of assets are in
cash only, the Net Proceeds are distributed in accordance with the terms of
Section 4 hereof and the Borrower is in full compliance with the terms of
Section 4 hereof and this Agreement, and (c) all gross proceeds and other monies
from the buyer of any such assets and Properties are wired directly to the
Administrative Agent (and not to the Borrower, the Parent, any of their
Subsidiaries or any other Person) pursuant to instructions from the Borrower and
its Subsidiaries whereupon the Administrative Agent shall distribute such funds
as set forth in Section 4 hereof,

                   (i) the Borrower may consummate the sale of its Collocation
         Facilities in St. Louis, Missouri, described on Schedule II hereof,
         provided that, (x) gross cash proceeds related to such asset sale are
         not less than $21,000,000 and (y) such asset sale is consummated in
         strict accordance with the terms of that certain Purchase and Sale
         Agreement executed by the Borrower and the buyer, dated as of October
         4, 2001, as amended by that certain First Amendment to Purchase and
         Sale Agreement, dated as of November 7, 2001, as in effect on November
         8, 2001 and

                   (ii) the Borrower may consummate the sale of its Collocation
         Facilities owned by the Borrower in Beaumont, Texas, as described on

         asset sale are not less than $300,000, and (y) such asset sale is
         consummated in strict accordance with the terms of that certain
         Purchase and Sale Agreement, executed by the Borrower and the buyer,
         dated as of September 17, 2001.

In connection with any asset sale permitted by this Section 5 or otherwise
consented to by the Lenders in accordance with the terms of the Credit
Agreement, the Administrative Agent is hereby authorized by each Lender to (i)
execute any and all releases deemed appropriate by it to release such assets of
the Borrower, the Parent and their Subsidiaries constituting Collateral from all
Liens and security interests securing all or any portion of the Obligations,
(ii) return to the Borrower any such Collateral in the possession of the
Administrative Agent, and (iii) take such other action as the Administrative
Agent deems necessary or appropriate in connection with such transaction and in
furtherance of the effectuation thereof.

         SECTION 6.        PROHIBITED ACTIONS. On the Effective Date and
continuing until the Termination Date, the Borrower shall not, and shall not
