         THIS SECURITIES PURCHASE AGREEMENT (the "Agreement") is made as of
April 25, 2002 by and among Pinnacle Holdings Inc., a Delaware corporation
("Pinnacle"), and Pinnacle Towers Inc., a Delaware corporation ("PTI" and
together with Pinnacle, the "Companies"), on the one hand, and Fortress
Registered Investment Trust, a Delaware business trust ("Fortress"), and
Greenhill Capital Partners, L.P., a Delaware limited partnership, and its
related partnerships identified on the signature pages hereof (collectively,
"Greenhill"). Fortress and Greenhill and their permitted assignees are sometimes
referred to individually as an "Investor" and collectively as the "Investors."
References to this Agreement herein shall include each of the Exhibits and
Schedules attached hereto. Capitalized terms not otherwise defined herein shall
have the meanings ascribed to such terms in Section 10.6.

         WHEREAS, the Companies desire to undertake the Restructuring (as
hereinafter defined) to be followed immediately by the merger (the "Merger") of
Pinnacle with and into a newly formed Delaware corporation to be formed by the
Investors solely for purposes of completing the Merger and with no liabilities
that would survive the Merger ("New Pinnacle"), with (i) New Pinnacle being the
surviving entity and the direct parent corporation of PTI and changing its name
to "Pinnacle Holdings Inc." and (ii) each of the New Common Shares (as
hereinafter defined) issued by Pinnacle being converted into a New Common Share
of New Pinnacle and immediately following the effective time of the Merger no
other share of capital stock of New Pinnacle being issued or issuable other than
the Warrant Shares and the Employee Stock Option Shares (as hereinafter
defined);

         WHEREAS, in connection with the Restructuring, the Investors desire to
make a significant investment in Pinnacle which, upon completion of the Merger,
will become an investment in New Pinnacle;

         WHEREAS, to implement such investment, the Investors desire to purchase
from Pinnacle, and Pinnacle desires to issue and sell to the Investors, upon the
terms and subject to the conditions set forth herein, the New Common Shares;

         WHEREAS, in connection with the sale and purchase of the New Common
Shares, the Investors will have the benefit of the registration rights provided
for in the Investor Agreement being executed at the Closing of the transactions
contemplated hereby in the form attached hereto as Exhibit A (the "Investor
Agreement"); and

         WHEREAS, in order to effect the transactions contemplated by this
Agreement, New Pinnacle will adopt a certificate of incorporation and bylaws in
the respective forms attached hereto as Exhibit B and Exhibit C, respectively
(the "New Pinnacle Certificate of Incorporation" and the "New Pinnacle Bylaws").

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




                                   ARTICLE I

the resolution of any objections to the calculations of EBITDA (as hereinafter
defined), Cash Funding (as hereinafter defined) and Assumed Liabilities pursuant
to Section 2.3; provided, however, that, in the event the parties are not able

immediately available funds to an account designated at least three (3) Business
Days prior to the Closing Date by Pinnacle.

               (b) Execution and delivery of the Investor Agreement shall be

of full months occurring during the period beginning January 1, 2002 and ending
on the last day of the Last Applicable Month (the "Initial EBITDA Calculation"),
and (iii) the calculation of the Assumed Liabilities (the "Initial Assumed
Liabilities Calculation"). The "Last Applicable Month" shall be either: (i) the
month immediately preceding the month in which the Closing Date is scheduled to
occur if the Closing Date is scheduled to occur on any day after the 15th day of
the month in which the Closing Date occurs or (ii) the month prior to the month
immediately preceding the month in which the Closing Date is scheduled to occur

be determined in accordance with GAAP consistently applied, but in the case of

policy, (K) unreimbursed costs or expenses associated with any potential
settlement the Companies entering into in connection with the pending
shareholder lawsuit, (L) unreimbursed costs associated with the settlement of
any lawsuits in an amount not in excess of $2,000,000 in the aggregate, and (M)
expenses incurred by the Companies in connection with any potential transaction
with a potential investor in one or both of the Companies , and (ii) include the
monthly amount, if it would decrease EBITDA on a recurring going-forward basis,
of the reasonably expected impact of any breaches by the Companies of their
representations and warranties in Article III, in each case without giving
effect to any and all materiality exceptions contained therein; provided,
however, that any breach of a representation or warranty that results in a
$1,000 per month effect or less (individually) on EBITDA shall be ignored.

               (b) If any of the Investors (or the Committee with respect to the
Initial Cash Funding Calculation) has any objections to the Initial Cash Funding
Calculation, the Initial EBITDA Calculation or the Initial Assumed Liabilities
Calculation, such party will deliver a written statement describing their
objections in reasonable detail to the Companies not less than five (5) Business
Days after the receipt of the Initial Cash Funding Calculation, the Initial
EBITDA Calculation and the Initial Assumed Liabilities Calculation. The
Companies, the Investors and the Committee will use reasonable efforts to
resolve any such objections themselves. If a final resolution of such objections
is not made within five additional Business Days, the Investors, the Companies
and the Committee (as the case may be) will submit the issue to the Bankruptcy
Court for resolution on forty-eight (48) hours' notice. Any such party may
present expert testimony at the hearing, and the resolution by the Bankruptcy
Court will be final and binding as to any adjustments to the Initial Cash
Funding Calculation, the Initial EBITDA Calculation or the Initial Assumed
Liabilities Calculation, as applicable, with no party having the right to
appeal. The Closing shall be delayed until at least three (3) Business Days but
no more than ten (10) Business Days following the Bankruptcy Court's final
determination of the issue, and no party shall incur liability to any other
party for such delay. "EBITDA" shall mean the Initial EBITDA Calculation
provided by the Companies to the Investors pursuant to Section 2.3(a), together
with any revisions thereto pursuant to this Section 2.3(b), and the "Cash
Funding" shall mean the Initial Cash Funding Calculation provided by the
Companies to the Investors pursuant to Section 2.3(a), together with any
revisions thereto pursuant to this Section 2.3(b).

               (c) The Companies will make the work papers and back-up materials
used in preparing the Initial Cash Funding Calculation, the Initial EBITDA
Calculation and the Initial Assumed Liabilities Calculation, and the books,
records, and the financial staff of the Companies available to the Investors and
their accountants and other representatives, and to the Committee and their
advisors with respect to the Initial Cash Funding Calculation, at reasonable
times and upon reasonable notice at any time during (i) the review by the
Investors and the Committee of the Initial Cash Funding Calculation, the Initial
EBITDA Calculation and the Initial Assumed Liabilities Calculation, and (ii) the
resolution by the parties of any objections thereto.




                                       4


               (d) All documents delivered by the Companies to the Investors
pursuant to this Section 2.3 shall contemporaneously be delivered to the
Committee and its counsel and, in the case of the Initial Cash Funding
Calculation, and any adjustments thereto shall be subject to the reasonable
approval of the Committee.

         Section 2.4 Breaching Investor. Notwithstanding anything else contained
in this Agreement to the contrary, if each of the conditions of each party's
obligations to this Agreement set forth in Article VII have otherwise been
satisfied or waived and if one of the Investors breaches its obligation to
consummate the transactions contemplated herein (the "Breaching Investor"), the
other Investors (the "Non-Breaching Investors") may elect within thirty (30)
Business Days from such date (or, if earlier, may elect by the date six months
from the date hereof) that, but for the Breaching Investor's failure to close,
would have been the Closing Date, to assume or cause one or more other Persons
to assume all of the rights and obligations of the Breaching Investor (an
"Alternative Investor"); provided, that any such Alternative Investor which is
neither an affiliate of, or an investor in, an Investor as of the date of this
Agreement shall be subject to the reasonable approval of the Companies and the
Committee. In the event that the Non-Breaching Investors determine not to elect
to so assume or cause another Person to assume the Breaching Investor's rights
and obligations under this Agreement, the Companies and the Committee shall have
an additional thirty (30) Business Days (or, if earlier, until the date six
months from the date hereof) to secure an Alternative Investor; provided,
however, that such Alternative Investor shall be (x) required to enter into all
inter-investor agreements on the same terms that the Breaching Investor would
have been subject to had it completed the Investment and (y) subject to the
Non-Breaching Investors' consent, which consent shall not be unreasonably
withheld, it being agreed that it shall not be unreasonable for the
Non-Breaching Investors to fail to give their consent if the reputation,
business approach and industry expertise of such Alternative Investor shall not
be comparable to or superior to those of the Breaching Investor. If the
Non-Breaching Investors elect not to assume or cause another Person to assume
the Breaching Investor's rights and obligations under this Agreement and neither
the Companies nor the Committee secures an Alternative Investor, the Companies
and the Non-Breaching Investors shall each have the right to terminate this
Agreement without any liability (including without limitation Sections 5.3 and
8.2) to the other and without in any way releasing the Breaching Investor from
any liability for its breach or limiting the Companies' rights with respect to
the Breaching Investor.

                                  ARTICLE III

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANIES

vehicle, any reports or summaries required under ERISA or the Code and the most
recent determination letter received from the Internal Revenue Service with

Subsidiaries has incurred any unsatisfied liability under Title IV of ERISA or

Affiliate or any Subsidiary of incurring any such liability, other than
liability for premiums due the Pension Benefit Guaranty Corporation (which
premiums have been paid when due).

"multiple employer plan" within the meaning of Section 413(c) of the Code; or

time have been provided through a voluntary employees' beneficiary association
within the meaning of Section 501(c)(9) of the Code.

               (e) None of the Companies or any of the Subsidiaries has any
liability for unpaid contributions with respect to any Plan, each of them has
made all required contributions under each Plan for all prior periods and proper
accruals relating to each Plan have been made and are appropriately reflected on
the books of the Companies.

               (f) No Plan provides medical, surgical, hospitalization, death or

(other than (x) coverage mandated by statute or (y) benefits the full cost of
which is borne by the current or former employee (or his or her beneficiary)).

               (g) Except as expressly contemplated by this Agreement or as set

the limitations provided in Section 7.2(j), the consummation of the transactions
contemplated by this Agreement and the other Transaction Documents will not,
either alone or in combination with another event, (i) entitle any current or
former employee, agent, independent contractor or officer of the Companies or
any Subsidiary to severance pay, (ii) accelerate the time of payment or vesting,
or increase the amount of compensation due any such employee, agent, independent
contractor or officer, (iii) constitute a "change in control" causing an
increase or acceleration of benefits under any Plan, (iv) result in any payment
or benefit that will be characterized as an "excess parachute payment" within
the meaning of Section 280G(b)(1) of the Code or (v) result in any loss of
deduction for federal income tax purposes.

               (h) To the Knowledge of the Companies, there is no pending,
threatened or anticipated (i) assessment, complaint, proceeding, or
investigation of any kind in any court or government agency with respect to any
Plan (other than routine claims for benefits) or (ii) litigation relating to the
employment or termination of employment of any current or former employee of the
Companies or any of the Subsidiaries.

               (i) To the Knowledge of the Companies, the Companies and the
Subsidiaries are and have been in compliance in all respects with all applicable
federal, state and local laws, rules and regulations (domestic and foreign)
respecting employment, employment practices, labor, terms and conditions of
employment and wages and hours, in each case, with respect to employees. Neither
the Companies nor any of the Subsidiaries is a party to or bound by any
collective bargaining agreement or other labor union contract. No work stoppage
or labor strike by employees is pending or threatened; neither the Companies nor
any of the Subsidiaries is involved in or threatened with any labor dispute,
grievance or litigation relating to labor matters and no organizational effort
or other activity the purpose of which is to achieve representation of employees

Companies, except as set forth in Section 3.15 of the Companies' Disclosure
Schedule, (a) the conduct of the business of the Companies and the Subsidiaries
as currently conducted does not infringe upon or misappropriate the Intellectual
Property rights of any third party, and no claim has been asserted to the
Companies in writing that the conduct of the business of the Companies and the
Subsidiaries as currently conducted infringes upon the Intellectual Property
rights of any third party; (b) with respect to each item of Intellectual
Property licensed to the Companies or the Subsidiaries ("Company Licensed
Intellectual Property"), the Companies or the Subsidiaries have the right to use
such Company Licensed Intellectual Property in the continued operation of their
respective businesses pursuant to the terms of the license agreement governing
the use of such Company Licensed Intellectual Property; (c) the Company Licensed
Intellectual Property has not been adjudged invalid or unenforceable in whole or
in part; and (d) neither the execution of this Agreement nor the consummation of
the transactions contemplated hereby shall adversely affect any of the
Companies' rights with respect to the Company Licensed Intellectual Property.

         Section 3.16 Taxes.

         To the Knowledge of the Companies and except as set forth in Section
3.16 of the Companies' Disclosure Schedule:

               (a) The Companies have timely filed (or there have been filed on
their behalf) all Tax Returns required to be filed by them under applicable law,
and all such Tax Returns were and are true, complete and correct in all material
respects, except, in each case, for Tax Returns with respect to which the amount
of additional Taxes properly owing would not exceed, in the aggregate, $20,000.
Except to the extent adequately reserved for in accordance with GAAP and
reflected on the most recent balance sheets of the Companies contained in the
SEC Reports, and except for the possible Tax which may be due with respect to
the "built-in gains" in assets acquired directly or indirectly from any C
corporation within the meaning of the Code as identified on Section 3.16(a) of
the Companies' Disclosure Schedule, all Taxes due and payable by the Companies
have been timely paid, except for unpaid taxes which in the aggregate do not
exceed $50,000.

               (b) There are no Tax liens upon the assets of the Companies
except liens for Taxes not yet due or Permitted Encumbrances.

               (c) The Companies have complied with the provisions of the Code
relating to the withholding of Taxes, as well as similar provisions under any
other laws, and have, within the time and in the manner prescribed by law,
withheld, collected and paid over to the proper governmental authorities all
amounts required.

               (d) No audits or other administrative proceedings or court
proceedings are presently pending or, to the Knowledge of the Companies,
asserted with regard to any Taxes or Tax Returns of the Companies, except for
any audits or other proceedings (i) that will result in additional Taxes in an
amount not exceeding $20,000 in the aggregate, or (ii) with respect to which the
Companies have established adequate reserves in accordance with GAAP for any
resultant Taxes, which reserves are reflected on the most recent balance sheets
of the Companies contained in the SEC Reports.

               (e) Except for the two rulings dated July 18, 2000 and December
22, 1995, respectively, as issued by the Internal Revenue Service (the "IRS")
and previously delivered to the Investors by the Companies, the Companies have
not received a written ruling of a taxing authority relating to Taxes or entered
into a written and legally binding agreement relating to Taxes with any taxing
authority.

               (f) The Companies have not requested any extension of time within
which to file any Tax Return, which Tax Return has not since been filed.

               (g) The Companies have not agreed to and are not required to make
any adjustment pursuant to Section 481(a) of the Code (or any predecessor
provision) by reason of any change in any accounting method of the Companies,
and there is no application pending with any taxing authority requesting
permission for any changes in any accounting method of the Companies. To the
Knowledge of the Companies, the IRS has not proposed any such adjustment or
change in accounting method.



                                       16


               (h) Except as set forth on Schedule 3.16(h) of the Companies'
Disclosure Schedule, the Companies do not have any material liability for Taxes
of any Person other than the Subsidiaries (i) under Treasury Reg. Section
1.1502-6 (or any similar provision of state, local or foreign law), (ii) by
contract, or (iii) otherwise.

               (i) The Companies do not have, nor have they ever had, any income
which is includable in computing the taxable income of a United States person
(as determined under Section 7701 of the Code) under Section 951 of the Code.
None of the Subsidiaries are or have ever been a "passive foreign investment
company" within the meaning of Section 1297 of the Code. The Companies are not
and never have been "personal holding companies" within the meaning of Section
542 of the Code. There are no gain recognition agreements, within the meaning of
Treasury Reg. 1.367(a)-8 or any predecessor provision, between the Companies, on
one hand, and a stockholder of the Companies, on the other. There is no pending
or threatened action, proceeding or investigation by any taxing authority for
assessment or collection of Taxes with respect to the Companies in any
jurisdiction where the Companies have not filed a Tax Return. All dealings and
arrangements between and among the Companies and the Subsidiaries are at arm's
length and consistent with arm's length dealings and arrangements between or
among unrelated, uncontrolled taxpayers.

               (j) Each Subsidiary which is a partnership, joint venture or
limited liability company has been treated since its formation, and continues to
be treated for federal income tax purposes, as a partnership or as a disregarded
entity, and not as a corporation or as an association taxable as a corporation.

               (k) For purposes of this Section 3.16, all representations and
warranties with respect to the Companies are deemed to include and to apply to
each of the Subsidiaries and predecessors (and the Subsidiaries of such
predecessors).

               (l) Except for the possible impact of the failure to timely elect
that certain foreign Subsidiaries be treated as a partnership or a disregarded
entity as identified on Section 3.16(l) of the Companies' Disclosure Schedule,
for each of its taxable years, Pinnacle (and its predecessor, as applicable) was
organized, operated and duly qualified as a REIT under Section 856 of the Code
and the execution or delivery by the Companies of this Agreement and the
consummation by the Companies of the transactions contemplated hereby, will not
adversely affect the qualification of Pinnacle as a REIT for each taxable year
ending prior to or which includes the Closing Date, except for the possible
failure to satisfy the REIT qualification requirements of either Section
856(a)(5) or Section 856(a)(6) of the Code as a result of events occurring
concurrent with or subsequent to the Closing.

               (m) As used in this Agreement, (i) the term "Taxes" means any
federal, state, county, local or foreign taxes, charges, fees, levies or other
assessments, including all net income, gross income, sales and use, ad valorem,
transfer, gains, profits, excise, franchise, real and personal property, gross
receipt, capital stock, production, business and occupation, disability,
employment, payroll, license, estimated, stamp, custom duties, severance or
withholding taxes or charges imposed by any Governmental Entity, and includes
any interest and penalties (civil or criminal) on or additions to any such
taxes, and (ii) the term "Tax Return"



                                       17


means a report, return or other information required to be supplied to a
governmental entity with respect to Taxes including, where permitted or
required, combined or consolidated returns.

               (n) Each entity identified as a "Taxable REIT Subsidiary" of
Pinnacle (within the meaning of Section 856(l) of the Code) in Section 3.1(b)(i)
of the Companies' Disclosure Schedule, at all times since January 1, 2001, has
satisfied every requirement imposed by Section 856(l) of the Code. None of such
entities (i) operates or manages, has operated or managed, or will operate or
manage prior to the Closing Date a "lodging facility" or "health care facility"
within the meaning of Section 856(1)(4)(A) and 856(1)(4)(B) of the Code,
respectively, or (ii) licenses, has licensed, or will license prior to the
Closing Date, rights to any brand name under which any such lodging facility or
health care facility is operated.

               (o) The Companies have not, with regard to any assets or property
held or acquired by any of them, filed a consent to the application of Section
341(f)(2) of the Code, or agreed to have Section 341(f)(2) of the Code apply to
any disposition of a "subsection (f) asset" (as such term is defined in Section
341(f)(4) of the Code) owned by the Companies.

               (p) No material deficiencies for any Taxes have been proposed,
asserted or assessed against the Companies which have not been paid, except for
any deficiencies (i) that do not exceed $30,000 in the aggregate, or (ii) with
respect to which the Companies have established adequate reserves in accordance
with GAAP, which reserves are reflected on the most recent balance sheets of the
Companies contained in the SEC Reports, and there is no outstanding waiver of
the statute of limitations with respect to any Taxes or Tax Returns of the
Companies.

               (q) At the Closing Date, other than a corporation that is a
"Qualified REIT Subsidiary" of Pinnacle within the meaning of Section 856(i)(2)
of the Code or a "Taxable REIT Subsidiary" of Pinnacle within the meaning of
Section 856(l) of the Code, Pinnacle will not own (as determined for purposes of
Section 856 of the Code and the Regulations promulgated thereunder, including
Treasury Reg. Section 1.856-3(g) and with the same meaning as when used in the
Investment Company Act of 1940, as amended), directly or indirectly (i)
securities (other than "real estate assets" within the meaning of Section
856(c)(5)(B) of the Code) possessing more than 10% of the total voting power of
any issuer or (ii) securities (other than "real estate assets" within the
meaning of Section 856(c)(5)(B) of the Code) having a value of more than 10% of
the total value of the outstanding securities of any issuer, other than
securities satisfying the straight debt safe harbor of Section 856(c)(7) of the
Code.

               (r) At no time on or prior to the Closing Date, have the
Companies provided services to tenants other than services that (i) do not give
rise to "impermissible tenant service income" as defined in Section 856(d)(7) of
the Code or (ii) give rise to impermissible tenant service income with respect
to any property for any taxable year in an amount not in excess of one percent
of all amounts received or accrued by the Companies with respect to such
property during such year.

               (s) Pinnacle does not own and has not owned, directly or
indirectly (including through attribution under the Code), stock of any entity
that is treated as a corporation for federal income tax purposes other than a
stock of (i) "Qualified REIT Subsidiaries" within the



                                       18


meaning of Section 856(i)(2) of the Code, (ii) "Taxable REIT Subsidiaries"
within the meaning of Section 856(l) of the Code, or (iii) with respect to
periods prior to March 31, 2001, "preferred stock subsidiaries," the ownership
of which stock satisfied the provisions of Section 856(c)(4)(B) of the Code as
in effect during the term of such ownership.

               (t) Except as set forth in Section 3.16(t) of the Companies'
Disclosure Schedule, the Companies do not own and have not owned, directly or
indirectly (including through attribution under the Code), an interest in a
partnership or limited liability company in which Pinnacle was not the direct or
indirect (including through attribution under the Code) managing member or
general partner.

in connection with the acquisition of any Pinnacle Real Property or the leasing
of any Pinnacle Leased Real Property, except for consents the failure to obtain

                                   ARTICLE IV

                 REPRESENTATIONS AND WARRANTIES OF THE INVESTORS

         Except as specifically set forth in the disclosure schedule prepared
and signed by each of the Investors (the "Investors' Disclosure Schedule") and
delivered to Pinnacle simultaneously with the execution hereof, each Investor
hereby represents and warrants as to itself to each of the Companies that all of
the statements contained in this Article IV are true and complete as of the date
of this Agreement (or, if made as of a specified date, as of such date), and
will be true and complete as of the Closing Date as though made on the Closing
Date. Each exception set forth in the Investors' Disclosure Schedule is
identified by reference to, or has been grouped under a heading referring to, a
specific individual section of this Agreement and, except as otherwise
specifically stated with respect to such exception, relates to such section. The
exceptions, modifications, descriptions and disclosures in any Schedule attached
hereto are made for all purposes of this Agreement and are exceptions to all
representations and warranties set forth in this Agreement or in any agreement
or instrument delivered pursuant to or in connection with this Agreement.
Disclosure of an item in response to one Section of this Agreement shall
constitute disclosure in response to every Section of this Agreement
notwithstanding the fact that no express cross-reference is made. Disclosure of
any items not otherwise required to be disclosed shall not create any inference
of materiality. In the event of any inconsistency between statements in the body
of this Agreement and statements in the Investors' Disclosure Schedule
(excluding exceptions expressly set forth in the Investors' Disclosure Schedule
with respect to a specifically identified representation or warranty), the
statements in the body of this Agreement shall control:

         Section 4.1 Investment.

               (a) Each Investor is acquiring the New Common Shares for
investment for its own account, and not with a view to any resale or
distribution thereof in violation of the Securities Act. Subject to the terms of
the Investor Agreement, each Investor understands that the New Common Shares
have not and will not be registered under the Securities Act or any state
securities laws by reason of specific exemptions therefrom which depend upon,
among other things, the bona fide nature of the investment intent and the
accuracy of the Investor's representations as expressed herein.

               (b) Each Investor's financial condition and investments are such
that it is in a position to hold the New Common Shares for an indefinite period,
bear the economic risks of the investment and withstand the complete loss of the
investment. Each Investor has extensive knowledge and experience in financial
and business matters and has the capability to evaluate the merits and risks of
such New Common Shares. Each Investor qualifies as (i) an "accredited investor"
as such term is defined in Section 2(15) of the Securities Act and Regulation D
promulgated thereunder or (ii) a "qualified institutional buyer" as defined in
Rule 144A under the Securities Act.

                                       23


               (c) Each Investor (i) has had a complete opportunity to conduct a
due diligence investigation concerning the Companies' business operations,
financial affairs and prospects; (ii) has received all the information it
considers necessary or appropriate for deciding whether to enter into the
transactions contemplated by this Agreement and the other Transaction Documents;
(iii) has examined and reviewed Pinnacle's most recent proxy statement, Annual
Report on Form 10-K, Quarterly Report on Form 10-Q, and any other Exchange Act
reports filed with the Securities and Exchange Commission since the filing of
Pinnacle's most recent Form 10-K; and (iv) has, in conjunction with its legal
counsel and other advisors, evaluated the risk factors inherent in an investment
in the New Common Shares.

         Section 4.2 Rule 144. Each Investor acknowledges that the New Common
Shares to be purchased by the Investor must be held indefinitely unless
subsequently registered under the Securities Act and any applicable state
securities laws or unless exemptions from such registrations are available. Each
Investor is aware of and familiar with the provisions of Rule 144 promulgated
under the Securities Act which permit limited resale of securities purchased in
a private placement subject to the satisfaction of certain conditions.

         Section 4.3 Organization of the Investors. Each Investor is duly
organized and validly existing and in good standing under the laws of the
jurisdiction of its organization.

         Section 4.4 Authority of the Investors.

               (a) Each Investor has all right, power and authority to execute
and deliver this Agreement and the other Transaction Documents to which it is a
party, to consummate the transactions contemplated hereby and to comply with the
terms, conditions and provisions hereof applicable to such Investor.

               (b) The execution, delivery and performance by each Investor of
this Agreement and each of the other Transaction Documents to which it is a

of each Investor, have been duly authorized and approved by the requisite
actions of each Investor and do not require any further authorization or consent
of any Investor or its beneficial owners. This Agreement is the legal, valid and
binding agreement of each Investor, enforceable against such Investor in

applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws from time to time affecting the enforcement of creditors' rights generally.

         Section 4.5 Non-Contravention. The execution, delivery and performance
by each Investor of this Agreement and the other Transaction Documents to which
it is a party and the consummation of the transactions contemplated hereby and
thereby, will not (a) conflict with or result in a breach of any of the terms

lapse of time, or both, would constitute a default) under, or result in the

assets of the Investor pursuant to any agreement, instrument, franchise, license
or permit to which the Investor is a party or by which any of its properties or
assets may be bound or (b) violate or conflict with any judgment, decree, order,

or assets, other than such breaches, defaults or violations that are not
reasonably expected to impair the ability of the Investor to consummate the
transactions contemplated by this Agreement and the other Transaction Documents
to which it is a party. The execution, delivery and performance by each Investor
of this Agreement and the other Transaction Documents to which it is a party and
the consummation of the transactions contemplated hereby and thereby, do not and
will not violate or conflict with any provision of the organizational documents
of the Investor, as currently in effect. Except for filings under the HSR Act

their respective properties or assets by or before any court, arbitrator or
other Governmental Entity which (i) in any manner challenges or seeks to
prevent, enjoin, alter or delay the transactions contemplated by this Agreement
or any of the other Transaction Documents or (ii) if resolved adversely to any
Investor would reasonably be expected to have a material adverse effect on the
ability of the Investors to fulfill their obligations under this Agreement and
the other Transaction Documents. There is no judgment, decree, injunction, rule,
or order of any court, governmental department, commission, agency,
instrumentality or arbitrator outstanding against any Investor that could
reasonably be expected to have a material adverse effect on the ability of the
Investors to fulfill their obligations under this Agreement and the other
Transaction Documents. No Investor is in default under or in breach of any
order, judgment or decree of any court, arbitrator or other Governmental Entity
which would have a material adverse effect on the ability of the Investors
fulfill their obligations under this Agreement and the other Transaction
Documents.

         Section 4.8 Consents and Approvals. To the Knowledge of each Investor,
no consent, approval, authorization of, declaration, filing, or registration

Investor or (ii) hinder or reasonably be expected to hinder such Investor's
financial ability to perform its obligations hereunder and each Investor agrees
not to take any action that would reasonably be expected to result in
insufficient funds being available to such Investor or in hindering such
Investor's financial ability to perform its obligations hereunder. The

                                       28


         Section 5.3 No Solicitation of Alternative Proposals. (a) Except as
expressly permitted in writing by the Investors, from and after the date of this
Agreement, none of the Companies shall authorize or permit any of their
Subsidiaries or any of the Companies' or the Subsidiaries' directors, officers,
employees, representatives, agents and advisors (including any investment
banker, financial advisor, attorney, accountant or other representative retained
by any of them) (all such parties, "Representatives"), directly or indirectly,
to (i) solicit, initiate, or take any other action designed to solicit proposals
that constitutes, or would be reasonably expected to lead to, a proposal or
offer for a restructuring transaction pursuant to a plan of reorganization,
merger, consolidation, transfer or exchange of shares, debt refinancing or
similar transaction involving the Companies (collectively, an "Alternative
Proposal"), (ii) participate in any substantive discussions or negotiations
regarding any Alternative Proposal, except that discussions or negotiations may
be held with, and non-public information provided to, any holders of the Senior
Notes or other Persons controlled by such holders concerning an Alternative
Proposal, or (iii) enter into any letter of intent, agreement in principle,
acquisition agreement or other similar agreement related to any Alternative
Proposal. Upon execution of this Agreement, each of the Companies and the
Subsidiaries shall immediately cease any existing activities, discussions or
negotiations with any parties heretofore conducted with respect to any
Alternative Proposal. Notwithstanding anything to the contrary that may be set
forth in the foregoing, none of the Companies or any of their Representatives
will be precluded from providing information to, or discussing and negotiating
with, any Person that is considering making, or has made, an unsolicited bona
fide Alternative Proposal. In addition, none of the Companies or any of their
Representatives will be precluded from executing an agreement providing for an
Alternative Proposal or recommending any such Alternative Proposal to the
creditors and stockholders of the Companies, if in the good faith opinion of
Pinnacle's Board of Directors (in consultation with its financial advisors) such
Alternative Proposal provides a higher transaction value to the Companies than
the value of the transaction provided in this Agreement and that Pinnacle's
Board of Directors reasonably determines in good faith (after consultation with
outside legal counsel) that they are required to authorize such actions by their
fiduciary duties or under the Bankruptcy Code. No Person considering making an
Alternative Proposal shall be provided non-public information by the Companies
unless such Person has executed a confidentiality agreement with terms that are
materially no less favorable to the Companies than those contained in the
Confidentiality Agreement between Fortress and the Companies dated August 21,
2001 (the "Fortress Confidentiality Agreement") and the Confidentiality
Agreement between Greenhill and the Companies dated August 21, 2001 (the
"Greenhill Confidentiality Agreement," and, collectively with the "Fortress
Confidentiality Agreement," the "Confidentiality Agreements").

               (b) Each of the Companies shall notify the Investors immediately
(in no event later than 24 hours) after (i) receipt by the Companies of any
written Alternative Proposal by any Person that informs the Companies that it is
considering making, or has made, an Alternative Proposal, or (ii) the delivery
by the Companies of any non-public information in connection with an Alternative
Proposal or the granting of access by the Companies to the properties, books or
records of the Companies by any Person that informs the Companies that it is
considering making, or has made, an Alternative Proposal. Such notice shall be
made orally or in writing and shall indicate, to the extent not prohibited by
the terms of any confidentiality agreement, the identity of the offeror and
shall also indicate all the material terms and conditions of such proposal,
inquiry or contract.

                                       29


               (c) Notwithstanding any other provision of this Agreement, the
Companies agree that they will not (i) enter into a definitive agreement
relating to an Alternative Proposal unless such definitive agreement shall
provide for an obligation by the Companies to pay any portion of the Break-Up
Payment or Allowed Break-up Payment Claim, as the case may be, not theretofore
paid to the Investors pursuant to Section 8.2, in each case not later than
consummation of such Alternative Proposal, and (ii) consummate any Alternative
Proposal unless any portion of the Break-Up Payment or Allowed Break-up Payment
Claim, as the case may be, not theretofore paid to the Investors pursuant to
Section 8.2 shall be paid to the Investors not later than consummation of such
Alternative Proposal.

         Section 5.4 Access to Information. Each of the Companies shall, and
shall cause the Subsidiaries to, afford to each Investor and to the officers,
employees, accountants, counsel, financial advisors and other representatives of
such Investor, reasonable access during normal business hours from the date
hereof until the Closing to all the properties, books, contracts, commitments,
personnel, reports and records of or relating to the Companies or the
Subsidiaries, and during such period each of the Companies shall, and shall
cause their Subsidiaries to, furnish promptly to the Investors, any financing
source identified by the Investors in connection with the transactions
contemplated hereby and to any other person that the Investors may reasonably
request (a) a copy of each report, schedule, registration statement and other
document filed by it during such period pursuant to the requirements of federal
or state securities laws, (b) such operating reports, financial reporting
packages and other operational and/or financial information sent to management
or the Board of Directors of the Companies or to the banks with whom the
Companies and the Subsidiaries maintain credit facilities or lines of credit and
(c) all other information concerning its business, properties and personnel as
the Investors may reasonably request; provided, however, that nothing in this
Section 5.4 or otherwise shall require the Companies to furnish to the Investors
any materials prepared by the Companies' financial advisors or legal advisors.

         Section 5.5 HSR Approval. Each of the Companies shall cooperate with
each Investor in obtaining as soon as practicable all necessary governmental
consents and approvals, including without limitation, termination or expiration
of the waiting period under the HSR Act.

         Section 5.6 Termination of Rights Agreement. Pinnacle shall take all
steps necessary to terminate, effective prior to the Closing Date, the Rights
Agreement between Pinnacle and First Union National Bank, dated as of December
22, 2000 (the "Rights Plan").

         Section 5.7 Use of Proceeds. The proceeds received by the Companies in
respect of the Investment and the New Credit Facility shall be used by the
Companies in accordance with the Bankruptcy Plan.

         Section 5.8 Restructuring.

               (a) The Companies and the Subsidiaries shall, in coordination
with the Investors, use commercially reasonable efforts to restructure the
capitalization of the Companies and the Subsidiaries pursuant to the Bankruptcy
Plan (the "Restructuring"). In furtherance of and without limiting the
generality of the foregoing, the Companies, Pinnacle Towers III, Inc. or any
such other Subsidiaries as shall be determined pursuant to Section 5.8(g) shall
promptly



                                       30


commence a Bankruptcy Case and file the Bankruptcy Plan and related Disclosure
Statement in form and substance reasonably acceptable to the Investors and the
Committee, with the Bankruptcy Court and seek to obtain the Confirmation Order
with respect to the Bankruptcy Plan and the Break-Up Payment Order as
expeditiously as possible in light of all circumstances.

               (b) The Bankruptcy Plan will offer each holder of the Senior
Notes its pro rata share, determined in accordance with the fully accreted value
at maturity of the Senior Notes of such holder's Senior Notes as a portion of
the fully accreted value at maturity of all Senior Notes (with cash amounts
rounded down to the nearest cent), of the Senior Note Holders Pool Amount (as
hereinafter defined) (the amount as so determined per $1,000 fully accreted
value of Senior Notes at maturity, the "Senior Note Holder Consideration").
Subject to Section 5.8(c), the "Senior Note Holders Pool Amount" shall equal
$114,000,000, subject to possible increase under Section 5.8(d). Payments of the
Senior Note Holder Consideration shall be made in the form of either (i) 100% in
cash or (ii) at the election of the holder, up to 100% in New Common Shares,
with any remainder pursuant to the cash election, with holders that make no
election receiving the cash alternative; provided, however, that (x) the number
of the New Common Shares issued as Senior Note Holder Consideration (the "Share
Pool") shall not exceed 49.9% of the Required New Share Amount (the "Share Pool
Limit"), with any reduction in the amount of New Common Shares to be received by
individual holders needed to maintain the Share Pool Limit to be applied on a
pro rata basis among all holders electing to receive New Common Shares based on
the amounts elected to be received by them as a portion of the total number of
New Common Shares available to be so allocated, and (y) holders of the Senior
Notes who elect to receive 100% of their consideration in the form of New Common
Shares pursuant to Section 5.8(b)(ii) shall collectively have the right to
purchase at the Purchase Price per share up to 50% of any New Common Shares
remaining in the Share Pool after all the holders of the Senior Notes have made
their election pursuant to Section 5.8(b)(ii), with such purchase rights being
allocated among such electing holders based on the amounts elected to be
received by them pursuant to Section 5.8(b)(ii) as a portion of the total number
of New Common Shares available to be so allocated. In the event that there are
any Additional Shares (as defined below), in addition to their right to elect to
receive Senior Note Holder Consideration as set forth above in this Section
5.8(b), holders of the Senior Notes who elect to receive 100% of their
consideration in the form of New Common Shares pursuant to Section 5.8(b)(ii)
shall collectively have the right to purchase for cash at the Purchase Price per
share up to 50% of any Additional Shares, with such purchase rights being
allocated among such electing holders based on the amounts elected to be
received by them pursuant to Section 5.8(b)(ii) as a portion of the total number
of New Common Shares available to be so allocated and Senior Note holders
electing to receive all of their consideration in the form of New Common Shares.
The number of "Additional Shares" shall be the determined by dividing (i) the
amount, if any, by which the Required New Equity Amount shall exceed
$228,000,000 by (ii) the Purchase Price. Any holder of Senior Notes electing to
receive all or part of such holder's consideration in New Common Shares pursuant
to Section 5.8(b)(ii) may elect, subject to such holder becoming a party to the
Investor Agreement and the transfer restrictions contained therein, to have the
benefit of certain registration, preemptive and other rights, as provided in the
Investor Agreement. An election by a holder of Senior Notes under this Section
5.8(b) to receive a portion of such holder's consideration in (x) New Common
Shares shall be deemed to be an election to forego the same portion of any cash
consideration allocated to such holder pursuant to Section 5.8(d) or (y) in cash
shall be deemed to be an election to forego the same portion of any Warrants
allocated to



                                       31


such holder pursuant to Section 5.8(d)). In the event that the Closing shall
occur on a date more than three months from the date of this Agreement, each
holder of Senior Notes electing to receive cash consideration pursuant to this
Section 5.8(b) shall be entitled to receive as additional consideration (rounded
down to the closest cent) an amount equal to the product of (w) the amount of
cash consideration so elected, excluding for such purposes any amount allocated
pursuant to Section 5.8(d), times (x) .05, times (y) the number of days that
occurs after the date that is three months from the date of this Agreement
through the Closing Date, divided by (z) 365; provided, however, that the
aggregate amount of such additional consideration shall be reduced to the extent
needed to cause the Initial Cash Funding not to exceed $415 million, with any
such reduction being allocated among the holders of Senior Notes electing to
receive cash consideration pursuant to this Section 5.8(b) in proportion to
their respective amounts of cash consideration otherwise being received pursuant
to this Section 5.8(b). The Investors, in their sole discretion, may increase,
but not decrease, the consideration offered to the holders of the Senior Notes;
provided, however, if the consideration offered to the holders of the Senior
Notes is increased pursuant to this sentence, such holders may change any
election made pursuant to this Section 5.8(b).

               (c) In the event that the Cash Funding exceeds $415,000,000, the
holders of not less than 66-2/3% in aggregate face amount of the Senior Notes
not held by the Investors (the "Requisite Holders") may elect, on behalf of all
holders of the Senior Notes, to reduce the Senior Note Holders Pool Amount by
the amount by which the Cash Funding exceeds $415,000,000 and thereby cause the
condition set forth in Section 7.2(o) to be satisfied. In the event that as of
the Closing Date a Determination shall not have been made as to the Tax Amount,
and subject to the consent of the Investors to be given or denied in their sole
discretion, the Committee may elect, on behalf of all holders of the Senior
Notes, for the Companies to establish an escrow (the "Tax Escrow") as of the
Closing Date into which would be deposited from the funds that would otherwise
fund the Senior Note Holders Pool Amount such amount as may be agreed between
the Committee and the Investors in their mutual sole discretions.

               (d) The Bankruptcy Plan will offer to holders of the Convertible
Notes consideration in the form of (i) $500,000 in cash and (ii) Warrants to
purchase the number of New Common Shares equal to one-half the Warrant Amount,
with such rights and terms as set forth in the Warrant Agreement attached as
Exhibit G hereto, (individually, a "Warrant", and collectively, the "Warrants");
provided, however, that if the holders of the Convertible Notes do not vote, as
a class, in favor of the Bankruptcy Plan and provide full and enforceable
releases to the Companies, they shall receive no distributions under the
Bankruptcy Plan. In addition to the foregoing, the Bankruptcy Plan will offer,
on behalf of the Companies and their respective current and former officers,
directors and agents, a pool consisting of $500,000 in cash and Warrants to
purchase the number of New Common Shares equal to one-half the Warrant Amount,
which shall be shared pro rata to those holders of the Convertible Notes who
elect to give full and enforceable releases to the Companies and their
respective current and former officers, directors and agents; provided, that any
holder of Convertible Notes who does not affirmatively decline to provide such
release shall be deemed to have elected to provide such release and no
beneficiary of any such release may receive more consideration than such
beneficiary would have received had all holders of Convertible Notes provided
releases. The Bankruptcy Plan will offer to holders of the Common Stock,
together with those parties with claims arising from the purchase and sale of
the Common Stock, consideration in the form of



                                       32


Warrants to purchase the number of New Common Shares equal to one-half of the
Old Common Stock Amount; provided, however, that if the holders of the Common
Stock and such claims do not vote, as a class, in favor of the Bankruptcy Plan
and provide full and enforceable releases to the Companies, they shall receive
no distributions. In addition to the foregoing, the Bankruptcy Plan will offer,
on behalf of the Companies and their respective current and former officers,
directors and agents, a pool consisting of Warrants to purchase the number of
New Common Shares equal to one-half of the Old Common Stock Amount, which shall
be shared pro rata by those holders of the Common Stock, together with those
parties with claims arising from the purchase and sale of the Common Stock, who
elect to give full and enforceable releases to the Companies and their
respective current and former officers, directors and agents; provided, that any
holder of Old Common Stock who does not affirmatively decline to provide such
release shall be deemed to have elected to provide such release and no
beneficiary of any such release may receive more consideration than such
beneficiary would have received had all holders of Common Stock provided
releases. Warrants to purchase a fractional number of New Common Shares shall
not be issued and the number of Warrants to be received by any individual holder
of Convertible Notes or Common Stock shall be adjusted downward to the closest
whole number to satisfy such requirement. If either of the foregoing classes do
not vote to accept the Bankruptcy Plan or if either class does not receive any
distribution pursuant to the "cramdown provisions" of 11 U.S.C. ss.1129, then
the most junior class immediately senior to the unaccepting class (or the class
that did not receive any distribution) shall receive the distribution which
otherwise would have gone to such unaccepting class (or the class that did not
receive any distribution). For purposes of the immediately preceding sentence,
amounts being distributed solely in consideration of the receipt of releases
shall not be deemed distributions. Subject to the approval of the Companies and
the Committee, the Investors may increase, but not decrease, the consideration
offered to each of the holders of the Convertible Notes and the Common Stock,
except to the extent required by the "cramdown provisions" of 11 U.S.C. ss.1129.

               (e) All other claims against and interests in the Companies shall
be treated as set forth in the Bankruptcy Plan.

               (f) In connection with and conditioned upon the consummation of
the Bankruptcy Plan, New Pinnacle shall (i) adopt the Employee Stock Option Plan
in the form attached hereto as Exhibit F (the "Employee Stock Option Plan") with
the number of New Common Shares issuable thereunder equal to the Option Share
Amount and (ii) grant options to purchase New Common Shares to the Companies'
employees (the "Employee Stock Option Shares") in accordance with Section 5.8(f)
of the Companies' Disclosure Schedule.

               (g) The Companies shall reject, or cause the relevant
Subsidiaries to reject, those of the Companies' executory contracts and leases
(as such terms are used in the Bankruptcy Code) as may be consented to by the
Investors and shall cause each Subsidiary which is a party to such a rejected
executory contract or lease to file a petition for bankruptcy relief in
connection with the Restructuring Transaction. The aggregate amount of rejection
damages required to be paid by the Companies or Subsidiaries to the parties to
such executory contracts or leases, either by agreement with such parties or by
order of the Bankruptcy Court, shall be the "Lease Rejection Amount," which
shall increase the Required New Equity Amount and be funded by the Investors
through the purchase of New Common Shares. The Companies and the Investors shall
mutually agree as to which other Subsidiaries will file petitions for



                                       33


bankruptcy relief in connection with the Restructuring Transaction. In the event
the parties cannot agree, the decision of the Companies will prevail.

               (h) The Companies shall file the Bankruptcy Plan, and (x) if this
Agreement has been terminated prior to the commencement of the Bankruptcy Case
under circumstances in which the Investors are entitled to the Break-Up Payment,
a motion (the "Break-Up Payment Claim Motion") for allowance as a general
unsecured claim in each of the Companies' Bankruptcy Cases of the Investors'
claim for payment of the Break-Up Payment (the "Allowed Break-Up Payment
Claim"), together with all necessary supporting papers and a proposed Break-Up
Payment Claim Order substantially in the form of the order attached hereto as
Exhibit I, or (y) if this Agreement remains in force at the time of the
commencement of the Bankruptcy Case, a motion (the "Break-Up Payment Motion")
for approval of the Break-Up Payment, together with all necessary supporting
papers and a proposed Break-Up Payment Order substantially in the form of the
order attached hereto as Exhibit J. Prior to the termination of this Agreement,
the Companies shall submit to the Investors for their review and comment all
non-ministerial motions, orders, applications and supporting papers and notices
prepared by the Companies (including without limitation, forms of orders and
notices to interested parties) relating in any way to the Bankruptcy Case, prior
to their being filed with the Bankruptcy Court.

               (i) Concurrently with the consummation of the Bankruptcy Plan,
Pinnacle shall merge with and into New Pinnacle, with New Pinnacle being the
surviving entity and the direct parent corporation of PTI.

               (j) The Investors and the Companies agree that if facts and
circumstances relating to the Investors' ownership of New Common Shares arise
that would result in the loss of the Companies' qualification as a REIT upon
completion of the Closing, neither such facts or circumstances, nor any action
taken by the Investors in their efforts to maintain the Companies' qualification
as a REIT, will in any way affect the receipt or retention, by a holder of
Senior Notes who has elected to receive New Common Shares, of the full amount of
New Common Shares that such holder is otherwise entitled to receive pursuant to
the Restructuring. In the event such facts and circumstances arise, the
Investors may opt to either (i) preserve the Companies' qualification as a REIT
in a manner that does not reduce the amount of New Common Shares distributed to
any holder of Senior Notes who has elected to receive New Common Shares, or (ii)
consummate the transactions contemplated hereby notwithstanding any termination
of Pinnacle's status as a REIT that may occur. Each of the Investors and each of
the Companies hereby agrees to take any action necessary, including, without
limitation, removing the ownership limitations imposed by Article IV, Part B,
and Article IV, Part C of the Amended and Restated Certificate of Incorporation
of Pinnacle and causing the Board of Directors of New Pinnacle to exempt each
holder of Senior Notes who has elected to receive New Common Shares from the
application of the provisions of Section 2.1(a) of Part D of Article Four of the
New Pinnacle Certificate of Incorporation, to allow each holder of Senior Notes
who has elected to receive New Common Shares in the Restructuring to receive and
hold such New Common Shares without violating any limitations imposed by the
organizational documents of either Company or of New Pinnacle, and appropriately
reducing the Aggregate Stock Ownership Limit in Section 1 of Part D of Article
Four of the New Pinnacle Certificate of Incorporation to account for the
exemptions granted by the Board of Directors of New Pinnacle to the holders of
the Senior Notes who have elected to receive New Common Shares in the
Restructuring.



                                       34


         Section 5.9 Investor Agreement. At or prior to the Closing, Pinnacle
shall enter into the Investor Agreement for the benefit of the Investors and any
holders of Senior Notes who acquire New Common Shares and make the election to
become a party to the Investor Agreement pursuant to Section 5.8(b).

         Section 5.10 Corporate Governance. Immediately prior to the Closing,
Pinnacle shall cause the resignations of the directors listed in Section 5.10 of
the Companies' Disclosure Schedule. The Board of Directors of New Pinnacle from
and after the Closing through the first annual meeting of shareholders of New
Pinnacle following consummation of the Bankruptcy Plan, which will be no earlier
than May 1, 2003, shall have the following nine members: (i) Steven R. Day; (ii)
five members designated by the Investors in their sole discretion; (iii) in the
event that Abrams Capital shall acquire New Common Shares representing at least
10% of the New Common Shares outstanding as of the Closing Date, David Abrams or
a designee of David Abrams reasonably acceptable to the Investors; and (iv) two
(or, in the event that no director is appointed pursuant to clause (iii), three)
members to be established by the Investors identifying a number of proposed
members equal to one more than the available slots and the Committee having the
right to veto one proposed member. In the event that David Abrams or his
designee shall become a director, he or she shall be assigned to the class of
directors whose term will expire at New Pinnacle's 2005 annual meeting of
shareholders. The Investors shall have the ongoing right to appoint (i) five (5)
directors if the Investors hold a number of shares representing 50% or more of
Pinnacle's then outstanding Common Stock; (ii) four (4) directors if the
Investors hold a number of shares representing between 35% and up to 50% of
Pinnacle's then outstanding Common Stock; (iii) three (3) directors if the
Investors hold a number of shares representing between 20% and up to 35% of
Pinnacle's then outstanding Common Stock; and (iv) two (2) directors if the
Investors hold a number of shares representing between 10% and up to 20% of
Pinnacle's then outstanding Common Stock.

         Section 5.11 Delivery of Documents. The Companies shall promptly
deliver to the Investors copies of all filings by the Companies with the SEC.

         Section 5.12 Review of Audit. The Companies shall permit the accounting
representative of the Investors to review the audit (including the appropriate
review of company and auditor work papers) of the Companies' financial
statements for the year ended December 31, 2001.

         Section 5.13 Releases. In the event a Bankruptcy Case is commenced, the
Companies shall use commercially reasonable efforts to ensure that the
Confirmation Order shall provide, among other things, that the directors,
officers, advisors, attorneys, investment bankers and agents of the Companies,
each Investor and each holder of Senior Notes and their respective affiliates,
members, managers, shareholders, partners, representatives, employees, attorneys
and agents are released from any and all Litigation related to the Companies,
their business, their governance, their securities disclosure practices, the
purchase or sale of any of the Companies' equity or debt securities, the
Restructuring or the Restructuring Transaction.

         Section 5.14 Investor Compliance With Regulatory Requirements. To the
extent that an Investor is required under an applicable law or regulation
(including, but not limited to, the Bank Holding Company Act of 1956, as
amended, and as it may be further



                                       35


amended) to modify the terms of the New Common Shares, or to defer receipt of
certain rights and privileges associated with the New Common Shares including
the right to influence the management or policies of the Companies in order to
conform to the requirements of such law or regulation, the Companies will
cooperate with the Investor to take such steps as may be reasonably necessary to
conform the investment represented by the New Common Shares to the requirements
of such law or regulation; provided, that no such change shall reduce the Senior
Note Holder Consideration without the approval of the Committee.

         Section 5.15 Payment of Investors' Expenses. In the event that the
transactions contemplated by this Agreement are consummated, the Companies shall
pay directly or reimburse the Investors for up to an additional $1,500,000
(excluding any reimbursement of expenses received prior to the date hereof) of
their out-of-pocket costs and expenses, including the fees and expenses of
advisors, accountants, attorneys, consultants and other parties whom the
Investors have engaged to assist them in connection with a possible investment
in the Companies, incurred by the Investors in connection with the evaluation,
negotiation and consummation of this Agreement, the Restructuring, the other
Transaction Documents and the transactions contemplated hereby and thereby.

         Section 5.16 Tax Matters.

               (a) The Companies shall not, and shall not permit any Subsidiary
to, (i) make or rescind any election relating to Taxes if such action would
adversely affect the status of Pinnacle as a REIT or the status of any
Subsidiary that is currently a partnership as a partnership for federal income
tax purposes, (ii) without the written consent of the Investors, which consent
will not be unreasonably withheld, settle or compromise any material claim,
action, suit, litigation, proceeding, arbitration, investigation, audit or
controversy relating to Taxes over $100,000 unless such settlement or compromise
results in a change in taxable income or Tax liability that will reverse in
future periods and is therefore, by its nature, a timing difference or (iii)
change in any material respect any of its methods of reporting income or
deductions for federal income tax purposes from those employed in the
preparation of its federal income tax return for the taxable year ending
December 31, 2000, except as may be required by applicable law or except for
such changes that would reduce consolidated federal taxable income or
alternative minimum taxable income. Notwithstanding any other provision of this
Agreement, in the event that, after the date hereof, the Companies seek a
"Closing Agreement" from the IRS or a definitive ruling or settlement agreement
from the IRS or any state, local or foreign taxing authority on a matter that is
subject to a representation, warranty or covenant set forth in this Agreement or
any of the related transaction documents, then: (A) the Companies shall, or
shall cause such Subsidiary to, keep the Investors informed as to the status of
such agreement and any discussions, negotiations or arrangements related
thereto, and (B) the Companies shall not, and shall cause any such Subsidiary
not to, file or submit any document to any taxing authority in connection with
any such agreement without first providing the Investors with (1) copies of any
such document and (2) an opportunity to review and comment on any such document
prior to such filing or submission.

               (b) The Companies hereby agree to take any action at any time, or
from time to time, that in the reasonable judgments of the Companies and the
Investors is legally



                                       36


necessary for Pinnacle to maintain its qualification as a REIT within the
meaning of Sections 856-860 of the Code for all periods through the Closing
Date.

         Section 5.17 Notification of Certain Matters. From the date hereof
through the Closing, the Companies shall give prompt notice to the Investors of
the occurrence, or failure to occur, of any event the occurrence or failure of
which caused any of Companies' or Investors' respective representations or
warranties contained in this Agreement to be untrue or inaccurate in any
material respect; provided, however, that no such notification shall be deemed
for any purpose under this Agreement to permit the Companies to alter or amend
the representations and warranties contained herein.

or other action shall have become final and non-appealable; provided, that any
termination by the Companies pursuant to Section 8.1(b)(i) shall be subject to
the reasonable approval of the Committee and provided further that,
notwithstanding clause (i) above or any other provision of this Agreement to the
contrary, the Companies and the Investors may amend this Agreement without the
approval of the Committee to extend the termination date provided for in clause
(i) above for an additional month if at the time of such amendment the

are continuing to work diligently to satisfy any remaining conditions in Article
VII, it being understood that thereafter the Senior Note holders may withdraw

Companies recommends an Alternative Proposal, (iii) if the Companies enter into

cured within 30 days after the giving of written notice to the Companies, the
Committee and the other Investor; and (ii) by the Companies (subject to the
reasonable approval of the Committee if the Investors shall have indicated their

               (e) by the Investors, if the Companies have not complied with
their obligations under Section 8.2 relating to seeking Bankruptcy Court
approval of their obligations to pay the Break-Up Payment (including the timing
of the filing of a motion and proposed order related thereto that is reasonably
acceptable to the Investors in all respects) or if the Bankruptcy Court has not
issued an order approving such obligations, in form and substance reasonably
satisfactory to the Investors, within 45 days following commencement of the
Bankruptcy Case;

               (f) by the Companies, if (i) the Board of Directors of Pinnacle
determines in good faith after consultation with the Committee and after giving
due regard to the preferences expressed by the Requisite Holders that
termination of this Agreement is necessary



                                       43


in order for the Companies to accept any Alternative Proposal, or (ii) the
Bankruptcy Court has ordered the Companies to terminate this Agreement in order
to accept any Alternative Proposal; provided, that, the Companies shall have the
right to terminate this Agreement pursuant to clause (i) above only if they have

provisions thereof, and shall comply with the requirements of Section 8.2
relating to any required payment (including the timing of any payment) of the
Break-Up Payment or Allowed Break-up Payment Claim, as the case may be, prior to
termination of this Agreement pursuant to this Section 8.1(f);

Days after the Investors giving of written notice to the Companies or (ii) for
twenty (20) Business Days following delivery of any MAE Notice by the Companies;
provided, however, that the failure of the Investors to terminate this Agreement
based on the facts described in a MAE Notice shall not preclude the Investors
from thereafter terminating this Agreement or exercising its right not to
complete the transactions contemplated by this Agreement under Section 7.2(a) or
7.2(s) if other events, developments or circumstances when, considered in the
aggregate with the facts described in one or more MAE Notices, in the aggregate
constitute a Material Adverse Effect.;

               (i) by the Companies or the Non-Breaching Investor pursuant to
Section 2.4; or

               (j) by the Investors or the Companies (subject to the reasonable
approval of the Committee if the Investors have indicated their willingness to
complete the Closing), in the event the Commitment Letter is terminated by the
lenders thereunder or expires and either (i) within twenty (20) Business Days
after such termination, the Companies do not secure alternative committed
financing that would satisfy Section 7.2(f)(i) (the "Alternative Financing") or
(ii) the lenders proposing to provide the Alternative Financing terminate their
commitment thereunder.

               (a) The Investors shall be entitled to receive from the Companies
a payment (the "Break-Up Payment") in an aggregate amount equal to $12,000,000

of any of their obligations hereunder, the Commitment Letter or a commitment
from lenders to provide the Alternative Financing remains in effect and either
or both of the following occurs: (i) the Investors terminate this Agreement
pursuant to Section 8.1(c) or the Companies terminate this Agreement pursuant to
Section 8.1(f): or (ii) this Agreement is terminated by the Companies pursuant
to Section 8.1(b) while in breach of this Agreement (it being understood that a
breach by the Company of its representations and warranties under Article III
shall not be deemed to be a breach for



                                       44


purposes of this clause (ii)) and within three months following such termination
the Companies enter into an agreement contemplating an Alternative Proposal
(other than a "stand alone" plan) providing a higher transaction value to the
Companies than the transaction provided by this Agreement.

               (b) If this Agreement has been terminated prior to the

the Investors shall occur (x) upon the closing of the first Alternative Proposal
completed following termination of this Agreement, or (y) as otherwise
prescribed in the Break-Up Payment Order if it shall have been entered by the
Bankruptcy Court.

               (c) In the event a Bankruptcy Case is commenced, the Companies
shall promptly, but in no event later than three (3) Business Days after
commencement of such Bankruptcy Case, take all action reasonably necessary,
including filing any motion, proposed order and supporting documents, to seek
(i) if this Agreement has been terminated prior to the commencement of the
Bankruptcy Case, allowance of the Break-Up Payment as a general unsecured claim
in each of the Companies' Bankruptcy Cases, or (ii) if this Agreement remains in
force at the time of the commencement of the Bankruptcy Case, approval from the
Bankruptcy Court of the Companies' obligation to pay the Break-Up Payment to
each Investor as administrative expenses in each of the Companies' Bankruptcy
Cases. Any and all motions and other documents filed by the Companies in
connection with their obligations under this Section 8.2 must be reasonably
acceptable to each Investor.

               (d) The Companies acknowledge and agree that (i) the payment of
the Break-Up Payment is an integral part of the transactions contemplated by
this Agreement, (ii) in the absence of the Companies' obligations to make this
payment, neither Investor would have entered into this Agreement and (iii) time
is of the essence with respect to the payment of the Break-Up Payment.

               (e) Notwithstanding any other provision of this Section 8.2,
neither Investor shall be entitled to any Break-Up Payment or any other claim
against or recovery from the Companies upon any termination of this Agreement if
any Investor caused such termination by breaching any of its representations,
warranties or covenants and such Investor fails to cure its breach after thirty
(30) days' written notice thereof.
