                            CONSENT TO PLAN AMENDMENT
                 AND ACKNOWLEDGEMENT OF EMPLOYMENT ARRANGEMENTS

         This Agreement is made as of the 15th day of July, 2003, between
Pinnacle Holdings Inc. (the "Company") and Jeffrey Langdon ("Optionee").

         Optionee has been granted options (the "Options") pursuant to the
Pinnacle Holdings Inc. Employee Stock Option Plan (the "Plan"), and Optionee and
the Company are currently parties to one option agreement (the "Option
Agreement"), attached as Exhibit A hereto, with respect to the Options, setting
forth the terms and conditions of the Options.

         In consideration of valuable consideration, Optionee hereby agrees with
the Company as follows:

         1. Option Plan Amendments. Notwithstanding any of the provisions, terms
or conditions of the Plan, the Option Agreement or other agreement to the
contrary, Optionee consents to the proposed amendments to be made by the Board
of Directors of the Company to the Plan (which amendments may be made prior to
the time this agreement is delivered) which are set forth in the marked version
of the Plan attached hereto as Exhibit B (the "Amended Plan").

         2. Option Agreement. Optionee and the Company understand and agree that
the Amended Plan will fully supersede the Plan and the terms of any other
agreement between the Optionee and the Company and that, since the Plan's
provisions are incorporated into the Option Agreement, the Option Agreement will
be amended by the Amended Plan to the extent that there are any inconsistencies
between the Amended Plan and the Option Agreement. The Option Agreement will
also be amended by the provisions set forth in paragraphs 3 and 4 below.
Optionee agrees that except as set forth in the Option Agreement or this
agreement, no other agreement shall be deemed to contain any provisions
governing the terms and conditions of the options granted pursuant to the Option
Agreement.

         Optionee acknowledges that the Company and Optionee have not entered
into any separate agreement which provides for different vesting terms, whether
conditioned upon the occurrence of any event relating to the Company or the
Optionee or otherwise.

         3. Vesting Provisions. In addition, Optionee and the Company understand
and agree that Section 3(a) of the Option Agreement is hereby amended to replace
the words "over a three year period on each anniversary of the Date of Grant"
with the words "over a three year period on each anniversary of January 1,
2003."

         4. Number of Shares Covered by Option. Optionee hereby agrees that the
number of $10 Shares (as defined in the Option Agreement) under the Option
Agreement is 20,500 and that the number of $20 Shares (as defined in the Option
Agreement) under the Option Agreement is 20,500.

         5. No Other Equity Interests. Optionee acknowledges, and hereby
represents and warrants to the Company, that except for the securities covered
by the Option Agreement, the Optionee has not been promised by the Company or
any other person or entity, and the Optionee has no right, title or interest in
any stock of the Company or any options, warrants, rights or other securities
convertible into or exchangeable for any stock or any options, warrants, rights
or other securities of the Company or any of its subsidiaries.

         6. No Other Agreements. Optionee acknowledges, and hereby represents
and warrants to the Company, that except for the agreement attached as Exhibit C
hereto, there are no written or other agreements between the undersigned and the
Company or any subsidiary thereof (or any predecessor thereto) that are not null
and void, and that the agreement attached as Exhibit C hereto, except to the
extent superceded by Option Agreement (as amended pursuant hereto) and this
Agreement, constitutes the entire agreement between the undersigned and the
Company with respect to the employment of the undersigned.

         7. Governing Law. This agreement shall be governed by the laws of the
State of Delaware, without regard to the conflicts of laws provisions thereof.

                                       ACKNOWLEDGED AND AGREED:

Dear Stephen:

Pinnacle Towers Inc. is pleased to confirm our offer and your acceptance of
employment for the position of Vice President and General Counsel, reporting to
David J. Grain, President. Your duties and responsibilities will be those
described to you during your recent interview with Mr. Grain. This letter will
confirm our understanding and agreement with respect to principal details of
your employment.

As discussed, your employment will begin on Monday, June 2, 2003. This is an
exempt position, for which you will be compensated at a rate of $190,000.00
annually and paid on a semi-monthly (twice a month) basis. In addition, you will
receive an employment incentive in the amount of $50,000 gross, payable on the
first pay period of employment to assist you in relocating to the Sarasota,
Florida area. Alternatively, Pinnacle will allow the costs of the moving company
and the airline flights between Houston and Sarasota to be billed directly to
(or reimbursed by) Pinnacle, with the $50,000 employment incentive being
concurrently reduced by said amounts. This information is confidential and
should not be discussed with anyone other than your manager, Mr. Grain.
Applicable federal, state and local taxes will be withheld from each paycheck,
as will be any additional deductions you choose to make. An annual review will
also be conducted after twelve (12) months of continuous employment.

Subject to Board confirmation, you will be granted an option to purchase that
number of shares of the common stock of the Company (the "Shares") representing
one quarter of one percent (.25%) of the fully diluted common shares of the
Company as of the date hereof (the "Option") with one half of the Shares
underlying the Option having an Exercise Price per Share of $10 (the "$10
Shares") and one half of the Shares underlying the Option having an Exercise
Price of $20 (the "$20 Shares," and together with the $10 Shares, the "Option
Shares"). The Option shall become vested and exercisable over a three-year
period with one-third of the $10 Shares and one third of the $20 Shares vesting
on each of the 1st, 2nd and 3rd anniversaries of your date of employment. The
Option shall be governed by the terms of an option agreement, the terms of which
shall be provided by the Company at a later date.

In the event the Company consummates an underwritten public offering of Company
common stock, pursuant to an effective registration statement filed under the
Securities Act of 1933, as amended, at any time during employment with the
Company, you will be entitled to have your Shares treated the same as shares of
the Company common stock held by other senior executive officers of the Company
with respect to registration rights relating to the Shares.

Your first 90 days of employment with Pinnacle Towers Inc. are considered an
introductory or probationary period. Completion of the introductory or
probationary period does not guarantee continued employment for any specified
period of time. In the event your employment is terminated by the Company for
non-cause, you will receive six months Base Salary and benefits under COBRA
(once elected).

The Company provides a very comprehensive benefits package. You will be eligible
to participate in our health, dental and vision plans upon completion of
one-month employment. Currently, employees of Pinnacle make a minimal
contribution towards the cost of health, dental and vision coverage for
themselves or their families. The Company also provides basic life insurance and
accidental death and dismemberment and dependent life insurance coverage at no
cost to employees. However, the Company reserves the right to announce changes
to the benefit plan administration. A benefit information package will be made
available to you at new hire orientation.

The Company offers a 401(k) plan to all employees upon date of hire. There are a
variety of investment options to choose from. The Company does not currently
make any matching contributions.

By accepting this offer and in exchange for employment with the Company, you
agree that all disputes, claims and controversies between you and the Company,
its affiliates, agents and successors will be resolved by final and binding
arbitration pursuant to the Federal Arbitration Act and the procedures of the
American Arbitration Association. By agreeing to final and binding arbitration,
you acknowledge that you are waiving any rights to a jury trial for all such
disputes, claims and controversies.

To prevent any misunderstanding between us, this letter will supersede any
discussions or written documents between us or between you and any other
representatives of Pinnacle regarding your employment. This letter sets forth
the entire understanding between us regarding your employment, and may not be
amended or modified except by a document in writing signed by both of us.

Please understand that while it is our hope and belief that our relationship
will be a long one, this is an offer of employment on an "at will" basis. The
application form explains the conditions of employment and compensation with
Pinnacle Towers Inc. are "at will" in that they can be terminated with or
without cause, and with or without notice, at any time, at the option of either
Pinnacle Towers Inc. or yourself, except as otherwise provided by law. The terms
of this offer letter, therefore, do not and are not intended to create either an
express and/or implied contract of employment with Pinnacle Towers Inc. No
manager or representative of Pinnacle Towers Inc., other than an officer of
Pinnacle Towers Inc. has authority to enter into any agreement for employment
for any specified period of time or to make any agreement or contract to the
foregoing, and any promises to the contrary may only be relied upon by you if
they are in writing and signed by an officer of Pinnacle Towers Inc.

As you are already aware, this offer of employment is contingent upon
satisfaction of the following conditions: proof of citizenship or unrestricted
authorization to work in the

                                       2

United States (please bring your acceptable documents on your first day of
employment); satisfactory completion of a background investigation, which may
include verification of past employment, education, felony criminal convictions
history, driving record and credit report, if applicable.

Stephen, if you agree with and accept the terms of this offer of employment,
please sign below and return this letter to my attention via hand delivery or
confidential fax (941) 308-0310. We are confident your employment with Pinnacle
Towers Inc. will prove mutually beneficial, and we look forward to having you
join our team.

You are scheduled for new hire orientation at 8:30 on Monday, June 2, 2003.
