ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

     On May 29, 1998, the Company entered into a Share Exchange Agreement with
MJA Communications Corp. ("MJA") and MJA's shareholders, Michael J. Anderson and
Constance S. Anderson and Fred Faulkner, III (collectively, the "Shareholders"),
pursuant to which the Company agreed to issue an aggregate amount of 397,023
shares of its Common Stock, at the time valued at $10,000,000, to the
Shareholders in exchange for all of the outstanding shares of MJA. The amount of
consideration was determined through arm's length negotiation which resulted in
a purchase price equal to 8.3 times MJA's after-tax earnings. Additionally, the
Company entered into an Employment Agreement with Mr. Anderson. As consideration
for Mr. Anderson's Employment Agreement, in addition to cash compensation and
bonuses, the Company agreed (1) to issue to him options to purchase 10,000
shares of the Company's Common Stock, (2) to set aside 100,000 additional
options to be granted to MJA employees at Mr. Anderson's discretion, and (3) to
issue 100 shares of Common Stock to each MJA employee continuously employed by
MJA for at least one year as of May 1, 1998. The Company also entered into a
Registration Rights Agreement with the Shareholders.

                            SHARE EXCHANGE AGREEMENT

     This Share Exchange Agreement ("Agreement") is entered as of the 29th day
of May 1998 by MICHAEL J. ANDERSON, CONSTANCE S. ANDERSON and FRED FAULKNER, III
(collectively the "Stockholders" and any of them individually a "Stockholder"),
MJA COMMUNICATIONS CORP., a Florida corporation ("MJA"), and WESTOWER
CORPORATION, a Washington corporation ("Westower").

                                    RECITALS

     A.   Westower wishes to acquire from Stockholders, on the terms and
conditions set forth in this Agreement, all of the issued and outstanding shares
of MJA.

     B.   The Stockholders are the owners of 100 shares of $1 par value, common
stock of MJA (the "MJA Stock").

     C.   The MJA Stock represents all of the issued and outstanding capital
stock of MJA; and the Stockholders desire to exchange the MJA Stock for common
stock of Westower (each share of such stock being a "Westower Share") so as to
accomplish and effect a share exchange under the Business Corporation Act of the
State of Washington.

     D.   It is the intent of the parties that the transaction qualify as a
corporate reorganization under Section 368(a)(1)(B) of the Internal Revenue Code
of 1986, as amended (the "Code") and as a "pooling of interests" for financial
accounting purposes.

                                  AGREEMENTS

     NOW, THEREFORE, in consideration of the foregoing recitals and of the
mutual agreements contained herein, Stockholders and Westower hereby agree as
follows:

                                   ARTICLE I
                                SHARE EXCHANGE

SECTION 1.1  EXCHANGE OF MJA STOCK

     Subject to the terms and conditions of this Agreement at the Effective Time
(as defined below) all the issued and outstanding shares of MJA Stock held of
record by 
<PAGE>
 
the Stockholders in the number and type set forth below opposite the name of
each Stockholder, shall be automatically exchanged for the right to receive at
least an aggregate of 384,616 Westower Shares as set forth below opposite the
name of each Stockholder (the "Share Exchange") plus the additional Westower
Shares as set forth in Section 1.2 below. Upon the effectiveness of the Share
Exchange, Westower shall be deemed to be the holder of record of all the issued
and outstanding shares of MJA Stock, and MJA shall continue to be governed by
the laws of the State of Florida.

</TABLE>

SECTION 1.2  INCREASE IN NUMBER OF WESTOWER SHARES ISSUED TO STOCKHOLDERS

     If at the Closing (as defined below) the closing price on the preceding day
for the Westower Shares, as reported in the Wall Street Journal, is less than
Twenty-Six U.S. Dollars ($26.00) per share, then additional Westower Shares
shall be issued within 15 calendar days to the Stockholders pro rata with their
ownership of MJA shares so that the aggregate value of the Westower Shares
issued in exchange for the MJA Stock equals Ten Million U.S. Dollars
($10,000,000.00) valued at the closing price for Westower Shares on the day
preceding the Closing. If, however, at Closing, the closing price on the
preceding day for the Westower Shares, as reported in the Wall Street Journal,
is more than Twenty-Six U.S. Dollars ($26.00) per share, then no additional
Westower Shares shall be issued beyond the 384,616 Westower Shares set forth in
Section 1.1. above.

     The Stockholders and Westower agree that on May 29, 1998--that date this
transaction closed--the Wall Street Journal reported a closing price for
Westower common stock of 25 3/16.  As a result, the Westower Shares which
Stockholders are entitled, collectively, pursuant to this Section 1.2 to receive
an aggregate of 397,023 shares, of which Westower will cause the transfer agent
for its shares to issue the following:  337,470 to Michael J. Anderson and
Constance S. Anderson and 59,553 to Fred Faulkner, III.  Westower shall request
that the transfer agent issue the stock with 

                                      -2-
<PAGE>
 
the restrictions set forth in this Agreement and deliver the shares by overnight
courier to the respective counsel for the Stockholders set forth in Section
12.4.

SECTION 1.3  ARTICLES OF SHARE EXCHANGE

     The parties hereto agree that the Share Exchange contemplated pursuant to
Section 1.1 shall be effectuated, at the Effective Time (as such term is
hereinafter defined), pursuant to articles of share exchange ("Articles of Share
Exchange") in accordance with applicable provisions of the Washington Business
Corporation Act. Such Articles of Share Exchange shall be filed with Secretary
of State of the State of Washington together with any other filings and
recordings required by Washington law in connection with the Share Exchange as
soon as practicable after the Closing. The term Effective Time, as used herein,
means the time at which the Share Exchange becomes effective under the laws of
the State of Washington.

SECTION 1.4  EXCHANGE RATIO

     At the Effective Time, each share of MJA Stock issued and outstanding
immediately prior to the Effective Time shall, by virtue of the Share Exchange
and without any action on the part of the holders thereof, automatically be
exchanged for the number of shares of Westower Shares equal to the number
obtained by dividing 384,616 by 100. Each certificate evidencing ownership of
MJA Stock outstanding immediately prior to the Effective Time shall, immediately
after the Effective Time, be exchanged for a certificate or certificates
evidencing ownership of the applicable number of Westower Shares.

SECTION 1.5  ADJUSTMENT FOR CHANGES

     Attached hereto as Exhibit 3.4 is a balance sheet of MJA which has been
prepared by MJA and dated as of April 30, 1998 ("April 30 Balance Sheet") which
reflects the financial position of MJA as of such date.  MJA will prepare, in
accordance with U.S. generally accepted accounting principles (GAAP) applied on
a basis consistent with MJA's past practice, and deliver to Westower a balance
sheet (the "Closing Date Balance Sheet") as of the Closing Date.  The Closing
Date Balance Sheet shall reflect changes in the financial position between April
30, 1998 and the Closing Date.  The equity of the Stockholders shown on the
Closing Date Balance Sheet will not have decreased by more than Two Hundred
Thousand Dollars (U.S.$200,000).  This calculation will exclude the effects on
the MJA's balance sheet, prepared in accordance with U.S. generally accepted
accounting principles (GAAP) applied on a basis consistent with MJA's past
practice, caused by the following allowed transactions of MJA:  (1) the
$1,500,000 distribution by MJA to Stockholders 

                                      -3-
<PAGE>
 
and (2) an aggregate of $250,000 in reasonable professional fees relating to the
transactions with Westower as of the Closing Date. If, after considering the
effect of these two allowed transactions, the decrease in the equity of the
Stockholders reflected on MJA's balance sheet as of the Closing Date is more
than $200,000, then the number of the Westower Shares distributed pro rata to
the Stockholders will be reduced by the amount of such decrease in excess of
$200,000 divided by U.S.$26.

SECTION 1.6  POWER OF ATTORNEY

     The undersigned Stockholder of MJA  is entering into this Agreement
pursuant to which his or her shares of MJA Stock will be exchanged for Westower
Shares,, and pursuant to which each Stockholder has agreed to indemnify Westower
against certain Damages (as defined in Section 10.1 hereof) in accordance with
the terms and procedures set forth in Article X hereof.  In connection with the
foregoing, the undersigned Stockholder hereby irrevocably constitutes and

to such claim, to communicate with Westower and to agree with Westower on behalf
of the undersigned Stockholder to the resolution or settlement of such claim, to
agree to the amount of such indemnification payable by the Stockholders and to
agree to the proration of the indemnification amount among the Stockholders,
including the undersigned Stockholder; and

          (b)  To make, exchange, acknowledge and deliver all such orders,
receipts, notices, requests, instructions, certificates, letters, contracts and

indemnification of Westower as fully as could the undersigned Stockholder if

                                      -4-
<PAGE>
 
The power of attorney granted hereby (i) is a special power of attorney coupled
with an interest and is irrevocable and (ii) shall survive the delivery of an
assignment or other transfer by the undersigned Stockholder of the whole or a
portion of his or her interest in the Westower Stock.

     The undersigned Stockholder hereby agrees that the Attorney shall have no
liability to the undersigned Stockholder for any actions taken in good faith by
the Attorney on behalf of the undersigned Stockholder with respect to or
pursuant to the power of attorney granted under this Section 1.6.

                MICHAEL J. ANDERSON, FRED FAULKNER, III, AND MJA

     Michael J. Anderson, Fred Faulkner, III, and MJA, to the best of their
knowledge formed after investigation and due diligence, represent and warrant,
jointly and severally, to Westower as follows:

SECTION 3.1  ORGANIZATION AND AUTHORITY OF MJA

     MJA is a corporation duly incorporated, validly existing and its status is
active under the laws of the State of Florida and has all requisite power and
authority (corporate and other) to own, operate and lease its properties and
assets and to carry on its businesses in the same manner as such businesses are
now being conducted.  

                                      -7-
<PAGE>
 
MJA is qualified, and licensed as a foreign corporation, to do business in each

authority to execute, deliver and perform his or her obligations under this
Agreement, and to consummate the transactions contemplated hereby.  All actions
on the part of MJA and its respective officers, directors and shareholders
necessary for the authorization, execution, delivery and performance of this
Agreement and the consummation of the transactions contemplated hereby have been
taken.  Assuming due authorization, execution, and delivery by Westower, this
Agreement has been duly executed and delivered by each Stockholder and
constitutes a legal, valid and binding obligation of such Stockholder,
enforceable against him or her in accordance with its terms, subject, as to
enforceability, to bankruptcy and equitable principles.

SECTION 3.3  NO SUBSIDIARIES, PARTNERSHIPS AND JOINT VENTURES

     MJA owns no interest in any joint venture, other partnership, or in any
Subsidiary.  The term "Subsidiary" as used in the preceding sentence shall mean:
(a) any corporation more than 40% of whose shares of stock having general voting
power under ordinary circumstances to elect a majority of the board of
directors, managers or trustees of such corporation, irrespective of whether or
not at the time stock of any other class or classes shall have or might have
voting power by reason of the happening of any contingency, are owned or
controlled directly or indirectly by MJA, or (b) any partnership 50% or more of
the partnership interests of which are owned or controlled, directly or

SECTION 3.4  FINANCIAL STATEMENTS

     Attached hereto as Exhibit 3.4 is a balance sheet of MJA dated as of April
30, 1998 ("April 30th Balance Sheet").  The Stockholders have heretofore
delivered to Westower accurate and complete copies of the balance sheet of MJA
at December 31 in each of 1996 and 1997, and the related statements of
operations and changes in financial position of MJA for each of the years then
ended (collectively, the "MJA Audited Financial Statements").  The December 31st
Balance Sheet and each of the MJA Audited Financial Statements present fairly,
in all material respects, the financial position of MJA at the respective dates
thereof, and the results of MJA' operations and changes in financial position,
for the periods indicated, all in conformity with GAAP.  The April 30th Balance
Sheet presents fairly, in all material respects, the financial 

                                      -8-
<PAGE>
 
position of MJA at April 30, 1998, consistent with the past accounting and
business practices of MJA.

SECTION 3.5  NO UNDISCLOSED LIABILITIES

     Except as disclosed on Exhibit 3.4 hereof, as of December 31, 1997 and as
of April 30, 1998 MJA had no known material liabilities or obligations of any
nature, whether absolute, accrued contingent or otherwise and whether due or to
become due, that were not reflected on the December 31st Balance Sheet, the
April 30th Balance Sheet or the MJA Audited Financial Statements, or in the
notes thereto, respectively (except those incurred by MJA in the ordinary course
of business thereafter or which are of a type not ordinarily reflected on a
balance sheet prepared in accordance with GAAP), and none of the Stockholders
knows nor does MJA know of any basis for assertion against MJA of any such
liability.

SECTION 3.6  NO DEALINGS WITH OFFICERS, DIRECTORS, AFFILIATES, OR STOCKHOLDERS
     OF MJA

     Except for the contractual agreements as listed on Exhibit 3.6 attached
hereto, as of the date of this Agreement, MJA does not have, directly or
indirectly, any contractual arrangements (including any express written
employment agreements) with any of its affiliates, stockholders, officers or
directors.  Without limiting the generality of the foregoing sentence, as of the
date of this Agreement and as of the Closing Date, no affiliates, stockholder,
officer, director or employee of MJA is, directly or indirectly, under
circumstances which individually or in the aggregate are material to the
business of MJA, a joint investor or venturer with, or owner, lessor, lessee,
licenser or licensee of any real or personal property, tangible or intangible,
owned or used by, MJA or was or is a lender to or debtor of MJA.

SECTION 3.7  TAXES

          (a)  MJA has filed all Tax Returns that it was required to file. All
such Tax Returns were correct and complete in all respects.  All Taxes owed by
MJA (whether or not shown on any Tax Return) have been paid or properly accrued.
Except as set forth on Exhibit 3.7(a), MJA is not currently the beneficiary of
any extension of time within which to file any Tax Return.  No claim has ever
been made by an authority in a jurisdiction where MJA does not file Tax Returns

liens on any of the assets of MJA that arose in connection with any failure (or
alleged failure) to pay any Tax.

                                      -9-
<PAGE>
 
          (b)  MJA has withheld and paid all Taxes required to have been
withheld and paid in connection with amounts paid or owing to any employee,
independent contractor, creditor, stockholder, or other third party.

          (c)  There is no dispute or claim concerning any Tax Liability of MJA
either (A) claimed or raised by any authority in writing or (B) as to which any
of the Stockholders and the directors and officers (and employees responsible
for Tax matters) of MJA has knowledge based upon personal contact with any agent
of such authority.  Exhibit 3.7(c) lists all Tax Returns filed with respect to
MJA that have been audited, and indicates those Tax Returns that currently are
the subject of audit.  The Stockholders have delivered to the Buyer correct and
complete copies of all federal income Tax Returns, examination reports, and
statements of deficiencies assessed against or agreed to by MJA since December
31, 1995.

          (d)  MJA has not waived any statute of limitations in respect of Taxes
or agreed to any extension of time with respect to a Tax assessment or
deficiency.

          (e)  MJA has not filed a consent under Code section 341(f) concerning
collapsible corporations.  MJA has not made any payments, is not obligated to

circumstances could obligate it to make any payments that will not be deductible

corporation within the meaning of Code section 897(c)(2) during the applicable
period specified in Code section 897(c)(1)(A)(ii).  MJA is not a party to any
Tax allocation or sharing agreement.  MJA (i) has not been a member of an

the best of MJA's Knowledge, the PBGC has not instituted proceedings to
terminate any of the Plans.  MJA HAS NOT received any notice of and has no
knowledge of a "reportable event" (within the meaning of Section 4043(b) of
ERISA).  Except as is set forth on Exhibit 3.28 hereof, no Plan to which Title
IV of ERISA applies has been terminated whose "date of termination" (within the
meaning of Section 4048 of ERISA) occurred after September 1, 1974.  To  MJA's
Knowledge, no event has occurred and there exists no condition or set of
circumstances as of the date of this Agreement, which presents a material risk
as of such date of the termination of any of the Plans which could result in any
liability on the part of MJA to the PBGC.

     (f)  FULL PAYMENT TO PLANS

     Full payment has been made of all amounts which MJA is required to pay
under the terms of each of the Plans as a contribution to the Plans as of the
last day of the most recent fiscal year of each of the Plans ended prior to the
date of this Agreement.  Except as disclosed on Exhibit 3.28 hereto, to MJA's
Knowledge none of the Plans nor any trust established thereunder has incurred
any "accumulated funding deficiency" (as defined in Section 302 of ERISA and
Section 412 of the Code), whether or not waived, as of the last day of the most
recent fiscal year of each of the Plans ended prior to the date of this
Agreement or the most recent contribution date as required under the terms of
any such Plans if later.

     (g)  PLANS IN COMPLIANCE WITH LAWS

     To MJA's Knowledge, each of the employee benefit plans maintained or
contributed to by MJA, including, without limitation, the Plans, is in
compliance with applicable federal, state and local laws, including but not
limited to ERISA and the applicable laws of jurisdictions outside of the United
States.  To the best of MJA's Knowledge each of the Plans that is intended to be
"qualified" has been administered in accordance with the requirements of Section
401(a) of the Code, but no determination letter has been requested or received
from the IRS with respect to qualification of such Plans, and no facts or
circumstances exist which would adversely affect the qualified status of the
Plans, except that the MJA's 401(k) Profit Sharing Plan is being revised to
reflect changes in the laws governing tax-qualified pension 

                                      -22-
<PAGE>
 
plans made by the Tax Reform Act of 1986 and other legislative and regulatory
actions. Except as may be disclosed on Exhibit 3.16 no matter relating to any of
the Plans is pending before any court or governmental agency. None of the
representations set forth in this subsection (g) are given with respect to any
multi-employer plan (as defined in Section 4001(a)(3) of ERISA) to which MJA
contributes or has contributed.

material respect.  MJA has not made any untrue statement of a material fact or
omitted to state a material fact necessary in order to make the statements made

Knowledge, Westower has not withdrawn, either partially or completely, from any
multi-employer plans.

     (d)  NO PROHIBITED TRANSACTIONS

     To Westower's Knowledge, neither any of the Plans nor any trust created
thereunder, nor any trustee or administrator thereof, has engaged in a
"prohibited transaction" (as such term is defined in Section 406 of ERISA) in
connection with which any of the Plans, any such trust, or any trustee or
administrator thereof, or any party dealing with the Plans or any such trust
could be subject to either a civil penalty assessed pursuant to Section 502(i)
of ERISA or a tax imposed by Section 4975 of the Code.

     (e)  NO PBGC LIABILITY

     As of the date of this Agreement, Westower is not aware and has received no
notice that it has incurred any liability to the Pension Benefit Guaranty
Corporation ("PBGC") with respect to any of the Plans or with respect to any
other employee benefit plan maintained or contributed to by Westower that has
been terminated or otherwise discontinued prior to the date of this Agreement.
To Westower's Knowledge, the PBGC has not instituted proceedings to terminate
any of the Plans.  Westower has not received any notice of and has no knowledge
of a "reportable event" (within the meaning of Section 4043(b) of ERISA). No
Plan to which Title IV of ERISA applies has been terminated whose "date of
termination" (within the meaning of Section 4048 of ERISA) occurred after
September 1, 1974.  To Westower's Knowledge, no event has occurred and there
exists no condition or set of circumstances as of the date of this Agreement,
which presents a material risk as of such date of the termination of any of the
Plans which could result in any liability on the part of Westower to the PBGC.

     (f)  FULL PAYMENT TO PLANS

     Full payment has been made of all amounts which Westower is required to pay
under the terms of each of the Plans as a contribution to the Plans as of the
last day of the most recent fiscal year of each of the Plans ended prior to the
date of this Agreement.  To Westower's Knowledge none of the Plans nor any trust
established thereunder has incurred any "accumulated funding deficiency" (as
defined in Section 302 of ERISA and Section 412 of the Code), whether or not
waived, as of the last day of the most recent fiscal year of each of the Plans
ended prior to the date of this Agreement or the most recent contribution date
as required under the terms of any such Plans if later.

     (g)  PLANS IN COMPLIANCE WITH LAWS

     To Westower's Knowledge, each of the employee benefit plans maintained or
contributed to by Westower, including, without limitation, the Plans, is in
compliance with applicable federal, state and local laws, including but not
limited to ERISA and the applicable laws of jurisdictions outside of the United
States.  To the best of Westower's Knowledge each of the Plans that is intended
to be "qualified" has been administered in accordance with the requirements of
Section 401(a) of the Code, but no determination letter has been requested or
received from the IRS with respect to qualification of such Plans, and no facts
or circumstances exist which would adversely affect the qualified status of the
Plans, except that the Westower's 401(k) Profit Sharing Plan is being revised to
reflect changes in the laws governing tax-qualified pension plans made by the
Tax Reform Act of 1986 and other legislative and regulatory actions.  No matter
relating to any of the Plans is pending before any court or governmental agency.
None of the representations set forth in this subsection (g) are given with
respect to any multi-employer plan (as defined in Section 4001(a)(3) of ERISA)
to which Westower contributes or has contributed.

SECTION 5.21  BLACKOUT PERIOD IN SECTION 6.12

     The restrictions imposed on Stockholders by Section 6.12 hereof are no more
restrictive than the similar restrictions imposed on the Chief Executive Officer

Agreement (including, but not limited to, the financial statement attached as

or misleading in 

                                      -35-
<PAGE>
 
any material respect. Westower has not made any untrue statement of a material
fact or omitted to state a material fact necessary in order to make the
statements made or information delivered in or pursuant to this Agreement not
misleading.

     Westower hereby covenants and agrees:

SECTION 7.1  CONFIDENTIALITY

     For itself and its affiliates, that it shall maintain in confidence and
neither disclose to any third party nor make commercial use of all or any part
of any information disclosed by Stockholders or MJA in connection with the
transactions contemplated hereunder; provided, however, that the obligations
contained in this Section shall not apply to such portions of such information
which were known to Westower without obligation of confidentiality prior to
disclosure to Westower by Stockholders or MJA, as the case may be, as
demonstrated by competent documentary evidence in Westower's possession, or
which properly became available to Westower, under conditions which do not
restrict further disclosure, from a third party source who shall not have
obtained such information either directly or indirectly from Stockholders or MJA
or which now or hereafter comes into the public domain without fault on the part
of Westower, or its employees.  With respect to information disclosed to
Westower related to the business and operations of MJA, the foregoing obligation
of confidentiality shall apply prior to the Closing of the transactions
contemplated by this Agreement, or, if no such Closing takes place, for a period
of two (2) years from the date of this Agreement.

SECTION 7.2  WESTOWER'S COOPERATION

     Westower agrees that promptly following the signing of this Agreement it
will approve the Plan of Share Exchange and will file the Articles of Share
Exchange with the secretary of State of the State of Washington.  Westower will
cooperate fully with Stockholders and MJA in promptly taking any and all action
or executing any and all documents appropriate to consummate the transactions
contemplated by this Agreement.

SECTION 7.3  REGISTRATION AND LISTING OF THE WESTOWER SHARES

     (a)  Westower will use all commercially reasonable efforts: (a) to file
with the Securities and Exchange Commission, within one hundred and eighty (180)
days of the Closing Date, a registration statement ("Registration Statement") on
Form S-3 

                                      -40-
<PAGE>
 
(or other form appropriate for registration of the Westower Shares for resale to
the public) under the Securities Act of 1933; and (b) thereafter, subject to
reasonable diligence and practicality, to cause such Registration Statement to
become effective and to remain effective until the date that is the earlier of:
(i) the date on which all of the Westower Shares have been sold by the
Stockholders or (ii) one year after the Closing Date. To the extent that any of
the Westower Shares are not listed with the American Stock Exchange on the date
of this Agreement, on or before the date that Westower files the Registration
Statement, Westower shall file with the American Stock Exchange a listing
application with respect to such shares. Westower agrees that any legend placed
on certificates representing the Westower Shares which restricts resale of the
Westower Shares will be removed, upon the effectiveness of the Registration
Statement.

     (b)  Notwithstanding the foregoing, the Company shall not be obligated to
effect any such registration pursuant to this Section 7.3 if (i) Form S-3 is not
available for such offering by the Stockholders, or (ii) the Company shall
furnish a certificate signed by the President of the Company stating that in the
good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its shareholders for such Registration
Statement to be filed and it is therefore essential to defer the filing of such
Registration Statement, in which event the Company shall have the right to defer
such filing for up to two periods of no more than 120 days each after delivery
of such certificate under this Section 2

     (c)  If (but without any obligation to do so) Westower decides to register
(including for this purpose a registration effected by Westower for shares other
than the Westower shares) any of its common stock on a form that would be
suitable for a registration involving Registrable Securities , the Company shall
promptly give each Stockholder written notice thereof.  Upon the written request
of each such Stockholder given within 20 days after mailing of such written
notice by the Westower, Westower shall use commercially reasonable efforts to
cause to be registered under the 1933 Securities Act (as amended) all of the
Registrable Securities specified in such written request.  In the event that
Westower decides, for any reason, not to complete the registration of shares of
common stock other than the Registrable Securities, the Company shall have no
obligation under this Section 7.3 to continue with the registration of the
Registrable Securities.

     For purposes of this Section 7.3, the term "Registrable Securities" means
any common stock of Westower issued or issuable in exchange for or in
replacement of, the Westower Shares, excluding in all cases, however, (i) any
Registrable Securities sold by a person in a transaction in which rights under
this Agreement are not 

                                      -41-
<PAGE>
 
assigned, (ii) any Registrable Securities sold in a public offering pursuant to
a Registration Statement filed with the SEC or sold to the public pursuant to
Rule 144 promulgated under the Act, or (iii) any Registrable Securities which
may be sold in the public market in a three-month period without registration
under the Act pursuant to Rule 144.

SECTION 7.4  TAX MATTERS

     Westower makes no representation or warranty with respect to, and expressly
disclaims any responsibility for, any Tax consequences to the Stockholders
arising out of the structure or terms of this Agreement, or the negotiation or
consummation hereof.  Each of the Stockholders have consulted with his or her
own tax advisor in such matter and shall be solely responsible for any such Tax
consequences.

SECTION 7.5  ELECTION TO CLOSE BOOKS

     Westower agrees that promptly following the Closing it will cooperate in
efforts, or cause MJA, to sign and deliver to the Internal Revenue Service the
Election to Close Books Upon S Corporation Termination and will execute the
Consent of Shareholders to such election.

SECTION 10.1  INDEMNIFICATION BY STOCKHOLDERS

     Subject to consummation of the Closing and the further provisions of this
Section 10.1, Stockholders hereby severally (in proportion to their share
ownership in MJA)agree to indemnify and hold Westower, its subsidiaries,
parents, affiliates, officers, directors, agents and employees (collectively,
the "Westower Indemnified Parties") harmless from and against and with respect
to any Damages to any Westower Indemnified Parties as hereinafter defined,
provided that:  (a) the Stockholders have received notice from Westower of a
claim for indemnification under this Section with respect to the matters covered
by Section 3.7 prior to the expiration of the applicable statute of limitations
with respect to such matters, and (b) the Stockholders have received notice from
Westower of a claim for indemnification under Section 10.2 with respect to all
other matters within one (1) year from the Closing Date.  The term "Damages," as
used herein, shall include any claim, action, loss, cost, expense, liability,
penalty or interest or damage, including, 

                                      -45-
<PAGE>
 
without limitation, reasonable counsel fees, and all reasonable costs and
expenses of all actions, suits, proceedings, demands, assessments, claims and
judgments resulting from, occurring in connection with, or arising out of any
breach of any representation, warranty or covenant by any of the Stockholders
made in the Agreement or in any of the Stockholders' Closing Documents.
Notwithstanding anything to the contrary set forth in this Article X,
indemnification of the Westower Indemnified Parties by the Stockholders shall in

Indemnified Parties will not be entitled to any indemnification, defense or
holding harmless, from the Stockholders, and the Stockholders will not be

claims exceed Two Hundred Fifty Thousand U.S. Dollars ($250,000) in the
aggregate, at which time the Stockholders shall be liable for all such Damages
including the first $250,000.

     The representations and warranties of the Stockholders and MJA herein
contained shall survive the Closing (y) with respect to matters covered by
Section 3.7 of this Agreement, solely for the period ending on the expiration of

representations and warranties contained in Article III and IV of this
Agreement, solely for a period of one (1) year from the Closing Date.

     The rights of the Westower Indemnified Parties under this Article X shall
be their exclusive remedy with respect to any claim for Damages; provided,

by any party to this Agreement of any of its rights or remedies arising by
reason of any claim of fraud.

SECTION 10.2  NOTICE OF ASSERTED CLAIMS BY THIRD PARTIES

     If any claim or assertion of liability is made or asserted by a third party
against a Westower Indemnified Party based on any liability or obligation which,
if established, would entitle the Westower Indemnified Party to indemnification
by the Stockholders, such Westower Indemnified Party shall with reasonable
promptness give to the Stockholders written notice of the claim or assertion of
liability and request the Stockholders defend the same, attaching to such notice
copies of any documents evidencing such claim which the Westower Indemnified
Party has received.  Failure to so notify the Stockholders shall not relieve the
Stockholders of any liability that the Stockholders might have to a Westower
Indemnified Party.  Within ten (10) days after 

                                      -46-
<PAGE>
 
such notice shall have been given, the Stockholders shall in writing advise the
Westower Indemnified Party whether they elect to defend against such claim. The
failure of the Stockholders to give such advice within such ten (10) period
shall be deemed an election not to defend against such claim. In the event that
such advice of election to defend is given within such ten (10) day period, then
the Stockholders shall have the right to defend, at their expense, actively and
in good faith against such claim with counsel of their own choice, which counsel
choice shall be subject to the reasonable approval of Westower, including,
without limitation, the right to settle and compromise such claim and to take
such appeals as may be necessary or desirable in connection therewith. The
Westower Indemnified Parties shall cooperate and assist in the defense of such
claim, to the extent reasonably requested by the Stockholders and, in the event
that the Westower Indemnified Parties desire additional counsel, they may retain
such counsel as they may select at their expense. Counsel selected by the
Stockholders and the Westower Indemnified Parties shall consult with and advise
each other, but the control of all such litigation, including the compromise or
settlement thereof and the taking of appeals, shall be determined by counsel for
the Stockholders.

SECTION 10.3  INVESTIGATIONS; WAIVERS

     The right of the Westower Indemnified Parties to the indemnification
provided in this Article X shall remain in effect notwithstanding any
investigation at any time by or on behalf of any party hereto or any waiver by
any party hereto of any condition to such party's obligations to consummate the
transactions contemplated hereby.

covenants, undertakings or agreements, or satisfaction of any of the conditions
to its obligations, contained in this Agreement, or (iii) the performance
(including performance to the satisfaction of a party) of any obligation set out
herein. Any waiver by any party of a condition to its obligation to perform this
Agreement and the subsequent Closing hereunder shall be in writing and shall be
without prejudice to the rights or remedies it may have arising out of any
subsequent or different breach of the same or any other any representation,
warranty, covenant or other agreement hereunder. Any waiver or extension
hereunder executed by Michael J. Anderson as representative of the Stockholders
shall likewise serve as a waiver or extension by all of the other Stockholders

individually.

          (b)  The provisions of this Agreement may not be changed, modified or
amended except by way of a writing duly executed by each of the parties hereto.

Stockholders shall be responsible for payment of any expenses related to the
preparation, execution and obtaining of any of Stockholders' Closing Documents
and Westower shall be responsible for any expenses related to the preparation,

invoices for expenses that the Stockholders have agreed to pay pursuant to the
provisions of this Section 12.1, then Westower shall promptly forward such bills
or invoices to the Stockholders. The Stockholders will make payment of such
bills or invoices promptly and in accordance with their terms of payment.

SECTION 12.2  COMPLIANCE WITH SECURITIES LAWS

     The Stockholders each agree, with respect to any reoffer, resale or
redistribution of any of the Westower Shares received in connection with the

successors, heirs and assigns.

SECTION 12.7  ENTIRE AGREEMENT; WRITING REQUIRED TO AMEND

     This Agreement, including the Exhibits hereto, constitutes the entire
agreement among the parties with respect to the subject matter hereof and
supersedes all prior agreements and understandings of the parties in connection
therewith.  No covenant or condition not expressed in this Agreement shall
affect or be effective to interpret, change or restrict this Agreement.

SECTION 12.8  PARTIAL INVALIDITY

     If any term, provision, covenant or condition of this Agreement is held by
any court of competent jurisdiction to be invalid, void or unenforceable, the
remainder of the provisions hereof shall continue in full force and effect.

SECTION 12.9  HEADINGS

     The sections headings provided in this Agreement are for convenience only
and are in no way intended to affect the meaning or import of any of the
language contained in this Agreement.

SECTION 12.10  PRECEDENCE OF DOCUMENTS

     In the event that there is a conflict between the terms of this Agreement

take precedence.

SECTION 12.11  CHOICE OF LAW; FORUM SELECTION

     This Agreement shall be governed by and construed according to the laws of
the State of Washington.  The federal and state courts located in King County,
State of Washington, shall have the exclusive jurisdiction over any dispute
under this 

                                      -51-
<PAGE>
 
Agreement, and each of the undersigned consents to personal jurisdiction in such
court.

SECTION 12.12  ENFORCEMENT COST

     Except as provided in Article X, if any civil action, arbitration, or other

an alleged dispute, breach, default, or misrepresentation in connection with any
provision of this Agreement, the successful or prevailing party or parties shall
be entitled to recover reasonable attorneys' fees, sales and use taxes, court
cost, and all expenses if not taxable court costs (including, without
limitation, all such fees, taxes, costs, and expenses incident to arbitration,
appellate, bankruptcy, and post-judgment proceedings), incurred in that civil
action, arbitration or legal proceeding, in addition to any other relief to
which such party or parties may be entitled.  Attorneys' fees shall include,
without limitation, paralegal fees, investigative fees, administrative costs,
sales and use taxes, and all other charges billed by the attorney to the
prevailing party.

SECTION 12.13  EQUITABLE REMEDIES

not specifically enforced.  Therefore, in the event of a breach or threatened
breach by any party of any provision of this Agreement, then the other parties
shall be entitled, in addition to all other rights or remedies, to an injunction
restraining such breach, without being required to show any actual damage or to
post an injunction bond, and/or to a decree for specific performance of the
provisions of this Agreement.

     Within 10 days of receipt of notice in writing of any audit of, or
deficiency notice to, MJA or the Stockholders which Westower receives with
respect to taxes for years ending on or prior to the Closing Date, Westower will
furnish a copy of such notice to Stockholders.  Westower shall cooperate with
and give Stockholders reasonable access during normal business hours on advance
notice to the records of MJA for the period under examination and shall use its
best efforts to furnish any other documents or instruments necessary to enable
the Stockholders' representatives to properly defend the audit, deficiency or
other proceedings.  If the Stockholders' exercise their right to prepare and
prosecute a tax refund claim, Westower will give Stockholders reasonable access
to the records of MJA and any other documents and instruments necessary to
enable the Stockholders' representatives to properly prepare and prosecute the
refund claim.

the transactions contemplated thereby must be approved in advance by Westower
and the Attorney appointed under Section 1.6.

SECTION 12.16  SURVIVAL

Agreement which by their terms require or may require performance after the
Closing shall survive the Closing and for such period following the Closing as
may be required for Westower, MJA or Stockholders', as the case may be, to
fulfill their respective obligations thereunder; such provisions shall terminate
by their terms thereafter.

     IN WITNESS WHEREOF, the parties to this Agreement have duly executed this
Agreement.

          (f) The term "REGISTRABLE SECURITIES" means any common stock of the
Company issued or issuable in exchange for or in replacement of, the Westower

a person in a transaction in which rights under this Agreement are not assigned,
(ii) any Registrable Securities sold in a public offering pursuant to a
Registration Statement filed with the SEC or sold to the public pursuant to Rule

     2.   FORM S-3 REGISTRATION AND LISTING OF THE COMPANY'S SHARES

          (a) The Company shall subject to the limitations set forth below, use
all commercially reasonable efforts to file with the SEC, within one hundred and
eighty (180) days after the Closing Date, a Registration Statement on Form S-3.
To the extent that any of the Registrable Securities are not listed with the
American Stock Exchange on the date of this Agreement, on or before the date
that the Company files the Registration Statement on Form S-3, the Company shall
file with the American Stock Exchange a listing application with respect to such
shares.

          (b) Notwithstanding the foregoing, the Company shall not be obligated
to effect any such registration pursuant to this Section 2 if (i) Form S-3 is
not available for such offering by the Holders, or (ii) the Company shall
furnish a certificate signed by the President of the Company stating that in the
good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its shareholders for such Registration
Statement to be filed and it is therefore essential to defer the filing of such
Registration Statement, in which event the Company shall have the right to defer
such filing for up to two periods of no more than 120 days each after delivery
of such certificate under this Section 2.

     3.   PIGGYBACK REGISTRATION

     If (but without any obligation to do so) the Company decides to register
(including for this purpose a registration effected by the Company for
shareholders other than the Holders) any of its common stock on a form that
would be suitable for a registration involving Registrable Securities, the
Company shall promptly give each Holder written notice thereof. Upon the written
request of each such Holder given within 20 days after mailing of such written
notice by the Company, the Company shall use commercially reasonable efforts to
cause to be registered under the Act all of the Registrable Securities specified
in such written request. In the event that the Company decides, for any reason,
not to complete the registration of shares of common stock other than the
Registrable Securities, the Company shall have no obligation under this Section
3 to continue with the registration of the Registrable Securities.

     4.   OBLIGATIONS OF THE COMPANY

     Whenever required under this Agreement to effect the registration of any
Registrable Securities, the Company shall, as expeditiously as reasonably
possible:

          (a) Prepare and file with the SEC a Registration Statement on Form S-3
with respect to such Registrable Securities and, subject to reasonable diligence
and practicality, use its commercially reasonable efforts to cause such
Registration Statement to become effective, and keep such Registration Statement
effective until the date that is the earlier of:  (1) the date on which all of
the Registrable Securities have been sold by the Stockholders or (2) one year
after the Closing Date.

          (b) Prepare and file with the SEC such amendments and supplements to
such Registration Statement and the prospectus used in connection with such
Registration Statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
Registration Statement.

          (c) Furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Act, and such other documents as they may reasonably request in order to
facilitate the disposition of all securities covered by such Registration
Statement.

          (d) Use commercially reasonable efforts to register and qualify the
securities covered by such Registration Statement under such other securities or
blue sky laws of such jurisdictions as shall be reasonably requested by the
Holders, provided that the Company shall not be required in connection therewith
or as a condition thereto to qualify to do business or to file a general consent
to service of process in any such states or jurisdictions.

          (e) In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the 

                                      -3-
<PAGE>
 
managing underwriter(s) of such offering. Each Holder participating in such
registration shall also enter into and perform its obligations under such an
agreement.

          (f) Notify each Holder of Registrable Securities covered by such
Registration Statement, during the time when a prospectus relating thereto
covered by such Registration Statement is required to be delivered under the
Act, of the happening of any event as a result of which the prospectus included
in such Registration Statement, as then in effect, includes an untrue statement
of a material fact or omits to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in the light
of the circumstances then existing.

          (g) At the request of any Holder selling Registrable Securities in
such Registration, furnish on the date that such Registrable Securities are
delivered to the underwriters for sale in connection such registration (i) an
opinion, dated such date, of legal counsel representing the Company for the
purposes of such registration, in form and substance as is customarily given by
Company counsel to underwriters in an underwritten public offering, addressed to
the Holders and (ii) a letter, dated such date, from the independent certified
public accountants of the Company, in form and substance as is customarily given
by independent certified public accountants to underwriters in an underwritten
public offering, addressed to the Holders.

     5.   OBLIGATIONS OF THE HOLDERS

     It shall be a condition precedent to the obligations of the Company to take
any action pursuant to this Agreement that the selling Holders shall furnish to
the Company such information regarding themselves, the Registrable Securities
held by them and the intended method of disposition of such securities as shall
be reasonably required to effect the registration of their Registrable
Securities and to execute such documents in connection with such registration as
the Company may reasonably request.

     6.   EXPENSES OF REGISTRATION

     In connection with any registration pursuant to this Agreement, the Company
shall be responsible for the payment of all expenses of the registration, with
the exception of (a) underwriting, broker or dealer discounts and commissions,
which shall be paid by the Company, the Holders and any other selling holders of
the Company's securities in proportion to the aggregate value of the securities
offered for sale by each of them, and (b) the fees and expenses of more than one
law firm acting as counsel to the selling Holders selected by a majority in
interest of the selling Holders, which additional counsel, if any, shall be paid
by the Holder or Holders that engaged such counsel.  The expenses to be paid by
the Company shall include, without limitation, all registration, filing and
qualification fees, printing and accounting fees, the fees and disbursements of
counsel for the Company and the fees and disbursements of one counsel for the
selling Holders.

                                      -4-
<PAGE>
 
     7.   BLACKOUT PERIOD

     At any time after the effective date of the Registration Statement, if the
Company is negotiating or involved in a significant transaction ("SIGNIFICANT"
for purposes of this Section being defined as an acquisition or disposition of,
or a merger with, a business entity having assets or revenues exceeding 10% of
the Company's consolidated assets or consolidated revenues) on written notice
from the Company that it requires the suspension by the Stockholders of the
distribution of any of the Westower Shares, then the Stockholders shall cease
distributing the Westower Shares for such period of time (the "BLACKOUT
PERIOD"), not to exceed 120 days from the time notice is sent until the Company
informs the Stockholders that the Blackout Period has been terminated.  Upon
notice by the Company to the Stockholders of such determination, the
Stockholders covenant and agree that they shall (a) keep the fact of any such
notice strictly confidential (b) promptly halt any offer, sale, trading or
transfer of any of the Westower Shares for the duration of the Blackout Period,
and (c) promptly halt any use, publication, dissemination or distribution of the
shelf registration provided for herein, each prospectus included therein, and
any amendment or supplement thereto by it and any of its affiliates for the
duration of the Blackout Period.

     8.   DELAY OF REGISTRATION

     No Holder shall have any right to obtain or seek an injunction restraining
or otherwise delaying any such registration as the result of any controversy
that might arise with respect to the interpretation or implementation of this
Agreement.

     9.   INDEMNIFICATION

     In the event any Registrable Securities are included in a Registration
Statement under this Agreement:

          (a) To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, any underwriter (as defined in the Act) for such
Holder and each person, if any, who controls such Holder or underwriter within
the meaning of the Act or the Securities Exchange Act of 1934, as amended (the
"1934 ACT"), against any losses, claims, damages or liabilities (joint or
several) (collectively, "LOSSES") to which they may become subject under the
Act, the 1934 Act or other federal or state law, insofar as such Losses arise
out of or are based upon any of the following statements, omissions or
violations (collectively, a "VIOLATION"):  (i) any statement or alleged
statement of a material fact contained in such Registration Statement, including
any preliminary prospectus or final prospectus contained therein, or any
amendments or supplements thereto, untrue in light of the circumstances under
which they were made, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading, or (iii) any violation or alleged violation by the Company of the
Act, the 1934 Act, any state securities law or any rule or regulation
promulgated under the Act, the 1934 Act or any state securities law.  The
Company will reimburse each such Holder, underwriter or controlling 

                                      -5-
<PAGE>
 
person for any legal or other expenses reasonably incurred by them in connection
with investigating or defending any Losses; provided, however, that the
indemnity agreement contained in this Section 9(a) shall not apply to amounts
paid in settlement of any such Losses if such settlement is effected without the
consent of the Company, which consent shall not be unreasonably withheld, nor
shall the Company be liable in any such case for any such Losses to the extent
the Losses arise out of or are based upon a Violation that occurs in reliance
upon and in conformity with written information furnished expressly for use in
connection with such registration by, or on behalf of, any such Holder,
underwriter or controlling person.

          (b) To the extent permitted by law, each selling Holder will indemnify
and hold harmless the Company, its officers, directors, agents and employees,
each person, if any, who controls the Company within the meaning of the Act,
each underwriter and each other Holder selling securities in such Registration
Statement, and any person who controls such Holder, against any Losses to which
the Company, such officer, director, agent, employee, controlling person,
underwriter or other selling Holder or person controlling such other selling
Holder may become subject under the Act, the 1934 Act or other federal or state
law, insofar as such Losses arise out of or are based upon any Violation, in
each case to the extent (and only to the extent) that such Violation occurs in
reliance upon and in conformity with written information furnished by, or on
behalf of, such Holder expressly for use in connection with such registration;
and each such Holder will reimburse any legal or other expenses reasonably
incurred by the Company, its officers, directors, agents, employees, persons
controlling such other selling Holder, underwriters or other selling Holders or
person controlling such other selling Holder in connection with investigating or
defending any such Losses; provided, however, that (i) the indemnity agreement
contained in this Section 9(b) shall not apply to amounts paid in settlement of
any such Losses if such settlement is effected without the consent of the
Holder, which consent shall not be unreasonably withheld and (ii) the
obligations of such Holders hereunder shall be limited to an amount equal to the
gross proceeds before expenses and commissions to each such Holder of
Registrable Securities sold as contemplated herein.

          (c) Promptly after receipt by an indemnified party under this Section
9 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 9, deliver to the
indemnifying party a written notice of the commencement thereof, and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly notified, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if, in the opinion of counsel for the indemnifying
party, representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding.  The failure to deliver written notice to the
indemnifying party within a 

                                      -6-
<PAGE>
 
reasonable period of time of the commencement of any such action shall relieve
such indemnifying party of any liability to the indemnified party under this
Section 9 to the extent prejudicial to its ability to defend such action, but
the omission so to deliver written notice to the indemnifying party will not
relieve it of any liability that it may have to any indemnified party otherwise
than under this Section 9.

     10.  REPORTS UNDER THE ACT

     With a view to making available to the Holders the benefits of SEC Rule 144
promulgated under the Act and any other rule or regulation of the SEC that may
at any time permit a Holder to sell securities of the Company to the public
without registration pursuant to the Act, the Company agrees to use commercially
reasonable efforts to:

          (a) Make and keep public information available, as those terms are
understood and defined in SEC Rule 144, at all times after 90 days from the
effective date of the first Registration Statement filed by the Company for the
offering of its securities to the general public;

          (b) File with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and

          (c) Furnish to any Holder, so long as the Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that
it has complied with the reporting requirements of the 1934 Act (at any time
after 90 days from the date on which it becomes subject to such reporting
requirements),(ii) a copy of the most recent annual or quarterly report of the
Company and such other reports and documents so filed by the Company, and (iii)
such other information as may be reasonably requested in availing any Holder of
any rule or regulation of the SEC that permits the selling of any such
securities without registration pursuant to Rule 144.

     11.  ASSIGNMENT OF REGISTRATION RIGHTS

     The rights to cause the Company to register Registrable Securities pursuant
to this Agreement may be assigned by a Holder to a transferee or assignee of
such securities who shall, upon such transfer or assignment, be deemed a Holder
under this Agreement; provided that the Company is, within a reasonable period
of time after such transfer, furnished with written notice of the name and
address of such transferee or assignee and the securities with respect to which
such registration rights are being assigned; provided, further, that such
assignment shall be effective only if immediately following such transfer the
further disposition of such securities by the transferee or assignee is
restricted under the Act and that such transferee or assignee is either (a) a
member of the immediate family or a trust for the benefit of any Holder that is
an individual, or (b) a transferee or assignee that after the transfer or
assignment holds (i) all of the Registrable Securities of the transfer, (ii)
Registrable Securities prior to the transfer, or (iii) at least 10% of the
outstanding equity securities of the Company immediately after such transfer.

hereto and adding a signature page executed by such additional Holder.

     14.  SEVERABILITY

                              EMPLOYMENT AGREEMENT
                              --------------------

     This Agreement is made this 29 day of May 1998, between Westower
Corporation, a Washington corporation (the "Company"), and Michael J. Anderson
("Employee").

                              W I T N E S S E T H:

     WHEREAS, the Company is acquiring all of the issued shares of MJA
Communications Corp., a Florida corporation ("MJA"), by which Employee has
previously been employed (the "Share Exchange Agreement");

     WHEREAS the Company desires to continue employing Employee and Employee
desires to accept such employment by the Company effective on the Closing Date
under the Share Exchange Agreement ("Exchange Date") subject to the terms and
conditions contained herein;

     WHEREAS, in serving as an employee of the Company, Employee will be in a
position in which Employee will participate in the use and development of
confidential proprietary information about the Company's, its subsidiaries' and
affiliates' present and future products, its customers and suppliers and the
methods which the Company and its employees use in competition with other
companies, as to which the Company desires to protect fully its rights;

     NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, and in consideration of the
promises and the mutual covenants and agreements herein set forth, the parties
agree as follows:

     1.   Employment.  The Company hereby employs Employee as the Company's
Senior Vice President and as Chairman and Chief Executive Officer of MJA, and
Employee accepts such employment with the Company and with MJA, subject to the
terms and conditions set forth herein. Employee shall perform all duties and
services regularly incident to the positions of Senior Vice President of the
Company, and Chairman and Chief Executive Officer of MJA, and Employee shall
perform such other duties and services as may be prescribed by the Bylaws of the
Company or established by the President or the Board of Directors of the Company
from time to time; provided, however, that (1) Employee's duties will not
require him to relocate his residence from South Florida and (2) the duties and
services Employee will be asked to provide will be at minimum of the nature of
his position as the Chief Executive Officer of MJA with the added
responsibilities for Company. In addition,

<PAGE>
 
when elected to the Board of Directors of the Company, Employee will faithfully
serve on such Board of Directors until his death, resignation or removal from
the Board. During his employment hereunder, Employee shall devote his best
efforts and attention, on a full-time basis, to the performance of the duties
required of him as an employee of the Company. For the purpose of this
Agreement, "full-time basis" means not less than 75 percent of the time Employee
spends working for both Company and others. Company acknowledges that Employee
is the CEO of other entitites.

     2.   Compensation.  As compensation for services rendered by Employee
hereunder, Employee shall receive:

          (a) An annual salary of $150,000, or such higher salary as shall be
determined by the Company at Employee's annual evaluation and compensation
review;

          (b) Insurance and other benefits equivalent to the benefits provided

     The Company agrees to effectuate Employee's election to its Board of
Directors at its next Board meeting and to propose his name to its Shareholders
as a member of the Company's Board of Directors in the solicitation of
shareholder votes at the Company's next annual meeting.

     Prior to the end of each calendar year of this Agreement, the Company may
review with Employee his compensation hereunder.  Any increase in salary or
changes in fringe benefits agreed upon by Employee and the Company at such
annual review shall become effective the following January 1 unless otherwise
agreed to by the Company and Employee.

     3.   Confidential Information and Trade Secrets.

     3.1  Employee recognizes that Employee's position with the Company requires
considerable responsibility and trust, and, in reliance on Employee's loyalty,
the Company may entrust Employee with highly sensitive confidential, restricted
and proprietary information involving Trade Secrets and Confidential
Information.

     3.2  For purposes of this Agreement, a "Trade Secret" is any scientific or
technical information, design, process, procedure, formula or improvement that
is valuable and not generally known to competitors of the Company, its
subsidiaries and affiliates. "Confidential Information" is any data or
information, other than Trade Secrets, that is important, competitively
sensitive, and not generally known by the public, including, but not limited to,
the Company's strategic and business plans, business prospects, training
manuals, product development plans, bidding and pricing

                                      -3-
<PAGE>
 
procedures, market strategies, internal performance statistics, financial data,
confidential personnel information concerning employees of the Company, supplier
data, operational or administrative plans, policy manuals, and terms and
conditions of contracts and agreements and such similar information relating to
subsidiaries and affiliates of the Company. The terms "Trade Secret" and
"Confidential Information" shall not apply to information which is (i) already
in Employee's possession (unless such information was obtained by Employee from
the Company, its subsidiaries, or its affiliates or was obtained by Employee in
the course of Employee's employment by the Company, its subsidiaries, or its
affiliates), (ii) received by Employee from a third party with no restriction on
disclosure, or (iii) required to be disclosed by any applicable law.

     3.3  Except as required to perform Employee's duties as an employee,
Employee will not use or disclose any Trade Secrets or Confidential Information
of the Company during employment, at any time after termination of employment
and prior to such time as they cease to be Trade Secrets or Confidential
Information through no act of Employee in violation of this Section 3.

     3.4  Upon the request of the Company and, in any event, upon the
termination of employment hereunder, Employee will surrender to the Company all
memoranda, notes, records, drawings, manuals or other documents pertaining to
the Company's business, Employee's employment (including all copies thereof) or
the business of the Company's subsidiaries or affiliates. Employee will also
leave with the Company all materials involving any Trade Secrets or Confidential
Information of the Company. All such information and materials, whether or not
made or developed by Employee, shall be the sole and exclusive property of the
Company, and Employee hereby assigns to the Company all of Employee's right,
title and interest in and to any and all of such information and materials.

     4.   Covenant Not to Compete.

     4.1  Employee hereby covenants and agrees with the Company that during the
period which is the longer of (a) three years, (b) the term of his employment
with the Company or (c) eighteen (18) months after the termination of his
employment, for any reason, with or without cause, Employee will not, except as
expressly permitted hereunder, directly or indirectly (i) operate, develop or
own any interest other than the ownership of less than 5% of the equity
securities of a publicly traded company, in any business which has significant
activities (viewed in relation to the business of the Company, its subsidiaries
or affiliates), or has announced intentions to focus significant resources,
relating to any business in which the Company, its affiliates, and its
subsidiaries is currently engaged and the business of building, owning,
managing, 

                                      -4-
<PAGE>
 
leasing or operating towers for wireless carriers or other similar entities (a
"Business"); (ii) compete with the Company or its subsidiaries and affiliates in
the operation or development of any Business within the North America (Canada,
Mexico, and the United States of America); (iii) be employed by any business
which owns, manages, or operates a Business; (iv) interfere with, solicit,
disrupt or attempt to disrupt any past, present or prospective relationship,
contractual or otherwise, between the Company, or its subsidiaries or
affiliates, and any customer, client, supplier or employee of the Company, or
its subsidiaries or affiliates; or (v) solicit any employee of the Company, or
its subsidiaries or affiliates, to leave their employment with the Company or
its subsidiaries or affiliates, as the case may be, or hire any such employee to
work for a Business. Employee shall not be entitled to circumvent the provisions
of this Section 4.1 by entering into a relationship with a Business as a
consultant, director, advisor, or otherwise, which has the effect of competing
with the Company, its affiliates or subsidiaries.

     4.2  If a judicial determination is made that any of the provisions of this
Section 4 constitutes an unreasonable or otherwise unenforceable restriction
against Employee, the provisions of this Section 4 shall be rendered void only
to the extent that such judicial determination finds such provisions to be
unreasonable or otherwise unenforceable. In this regard, the parties hereto
hereby agree that any judicial authority construing this Agreement shall be
empowered to sever any portion of the territory or prohibited business activity
from the coverage of this Section 4 and to apply the provisions of this Section
4 to the remaining portion of the territory or the remaining business activities
not so severed by such judicial authority. Moreover, notwithstanding the fact
that any provisions of this Section 4 are determined not to be specifically
enforceable, the Company shall nevertheless be entitled to recover monetary
damages as a result of the breach of such provision by Employee. The time period
during which the prohibitions set forth in this Section 4 shall apply shall be
tolled and suspended as to Employee for a period equal to the aggregate quantity
of time during which Employee violates such prohibitions in any respect.

     5.   Specific Enforcement.  Employee specifically acknowledges and
agrees that the restrictions set forth in Sections 3 and 4 hereof are reasonable
and necessary to protect the legitimate interest of the Company and that the
Company would not have employed Employee in the absence of such restrictions.
Employee further acknowledges and agrees that any violation of the provisions of
Sections 3 or 4 hereof will result in irreparable injury to the Company, that
the remedy at law for any violation or threatened violation of such Sections
will be inadequate and that in the event of any such breach, the Company, in
addition to any other remedies or damages available to it at law or in equity,
shall be entitled to temporary injunctive relief before 

                                      -5-
<PAGE>
 
trial from any court of competent jurisdiction as a matter of course and to
permanent injunctive relief without the necessity of proving actual damages. The
existence of any claim or cause of action on the part of Employee against the
Company, whether arising from this Agreement or otherwise, shall not constitute
a defense to the granting or enforcement of this injunctive relief. If the
Company is required to enforce any of its rights under this Agreement, the
Company shall be entitled to recover from Employee all reasonable attorneys'
fees, court costs and other expenses incurred by the Company in connection with
the enforcement of those rights.

     6.   Incentive Stock Options for Employee; Employee Discretion to
Distribute Shares, Stock Options and Distribution from Bonus Pool for MJA's
Employees.  MJA's employees will receive credit in any of the Company's employee
benefit plans for their years of service of MJA pre-Exchange Date, and MJA's
employees will not have any waiting period or pre-existing conditions in order
to continue their health insurance coverage. In addition, the Company will grant
Employee an option to purchase 10,000 shares, effective and priced on the
Exchange Date, of the Company's common stock pursuant to Westower Corporation
1998 Stock Incentive Compensation Plan or such successor option plan as the
Company and its shareholders may adopt (the "Plan"). In addition, the Company
agrees that as part of his employment hereunder as the Chief Executive Officer
for MJA, the Company will do what is reasonably necessary for the Employee to
distribute in his sole discretion the following compensation to employees of
MJA.

     (a)  For each employee who has been continuously employed by MJA for one
year as of May 1, 1998, 100 shares of the Company's common stock provided that
such stock will be issued pursuant to the Plan by the earlier of the date 15
business days after the Company files an S-8 with the Securities and Exchange
Commission for the Plan or July 15, 1998.

     (b) For each of the three years after the Exchange Date, a bonus pool equal
to ten (10) percent of the net pre-tax earnings (if any) of MJA in such year,
with net pre-tax earnings of MJA measured allocating Employee's compensation
hereunder as a cost of the Company and measured according to Generally Accepted
Accounting Principles, consistently applied, as reflected in the financial
statements for the Company prepared by its certified public accountants, without
any allocation to MJA for overhead of the Company and its subsidiaries other
than MJA.  This obligation of the Company will survive the termination of this
Agreement, but the distributions made after the effective date of any such
termination will be made by the successor Chief Executive Officer for MJA and
not Michael J. Anderson.

                                      -6-
<PAGE>
 
     (c)  In addition to whatever other compensation is provided for in this
Agreement, options pursuant to the Plan to purchase one or more shares of the
Company's common stock, effective and priced on the date of the grant, to
employees of MJA who have worked at MJA continuously for one year as of May 1,
1998; provided, however, that (i) the total number of options distributed
pursuant to the terms of this provision will in no event confer on such
employees any rights to purchase more than 100,000 shares of the Company's
common stock in the aggregate by all employees of MJA selected by Employee to
receive any such options and (ii) Employee will remain liable to the Company for
damages resulting from all options distributed to employees of MJA to purchase
in excess of 100,000 shares.  All such options will be exercisable within 10
years and become vested in employees of MJA according to the following schedule:
On the first anniversary of the Exchange Date, thirty three per cent (33%) of
the total shares granted; on the second anniversary of the Exchange Date;
thirty-three percent (33%) of the total shares granted; and on the third
anniversary of the Exchange Date, the remaining thirty-four per cent (34%) of
the total shares granted.  This obligation of the Company will survive the
termination of this Agreement, but the distributions made after the effective
date of such termination will be made by the successor Chief Executive Officer
for MJA and not Michael J. Anderson.

     All options granted hereunder or in connection with Employee's employment
hereunder shall constitute "incentive stock options" within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), to
the extent permitted under the Code and applicable rulings and regulations, or,
in Employee's discretion, nonqualified stock options.

     7.   Term of Agreement.  This Agreement shall be effective as of the
Exchange Date and shall continue for a term of three (3) years from the Exchange
Date unless terminated by either party in the manner set forth herein. This
Agreement shall be automatically renewed for successive one (1) year terms
unless written notice of termination is given by either party at least 90 days
prior to the end of the then current term.

     8.   Termination Upon Death or Disability of the Employee.  In the event
the Employee dies during the term of this Agreement, or the Employee is disabled
and unable to perform his duties in any material respect for a period of six (6)
months, this Agreement shall immediately terminate and neither the Employee nor
the Company shall have any further obligations hereunder, except that the
Company shall continue to be obligated under Section 2 hereof for any unpaid
salary, accrued benefits or 

                                      -7-
<PAGE>
 
unreimbursed expenses owed to Employee or his estate that have accrued but not
been paid as of the Termination Date.

     9.   Termination by Employee.  Employee may at any time terminate his
employment by giving the Company sixty (60) days prior written notice of his
intent to terminate the Agreement, unless the termination is because of Changed
Circumstances as set forth in Section 11. At the Termination Date, the Company
shall have no further obligation to Employee and Employee shall have no further
rights or obligations hereunder, except as set forth in Sections 3 and 4 above,
and except for the Company's obligation under Section 2 hereof for unpaid
salary, accrued benefits or unreimbursed expenses that have accrued but have not
been paid as of the Termination Date, unless termination is because of Changed
Circumstances, as set forth in Section 11.

     10.  Termination for Cause.  The Company shall have the right at any time
to terminate Employee's employment immediately for cause, which shall include
any of the following reasons: Employee's violation of the provisions of Sections
3 or 4 of this Agreement, gross neglect of duty, conviction under a state or
federal law involving commission of a crime against the Company, its
subsidiaries and affiliates (for purposes of this Section 10, the "Westower
Group") or a felony, willful failure or refusal to carry out lawful duties or
directions of the President or the Board of Directors of the Company reasonably
consistent with such duties, or the willful engaging by the Employee in gross
misconduct materially injurious to the Westower Group.

     Employee's obligations under Sections 3 and 4 hereof shall survive the
termination of the Agreement pursuant to this Section 10. In the event
Employee's employment hereunder is terminated in accordance with this Section,
the Company shall have no further obligation to make any payments to Employee
hereunder except for unpaid salary, accrued benefits or unreimbursed expenses
that have accrued but have not been paid as of the Termination Date.

     Notwithstanding the foregoing, any termination of Employee shall not be
considered a termination for cause and shall be considered a termination without
cause pursuant to Section 11 hereof, if such termination is effected without:
(1) 5 calendar days' notice to Employee setting forth the reasons for Company's
intention to terminate for cause; (2) an opportunity for Employee, together with
his counsel, to be heard before the Board of Directors of the Company; and (3)
delivery to the Employee of a notice of termination from the Board of Directors
of the Company finding that in the good faith opinion of the Board of Directors
of the Company there exists cause to terminate Employee pursuant to this Section
10.

                                      -8-
<PAGE>
 
     11.  Termination by Company Without Cause or by Employee for Changed
Circumstances.  The Company may terminate the employment relationship with
Employee without cause (which shall not include a termination pursuant to
Sections 8, 9 or 10) by giving Employee 15 days prior written notice.  Employee
may terminate the employment relationship with the Company for Changed
Circumstances by giving the Company 15 days prior written notice.  The term
"Changed Circumstances" as used in this Section 11 means (i) a reduction in
Employee's base salary and benefits, (ii) a material reduction in the scope of
Employee's authority and/or responsibilities, (iii) during the first three years
following the Exchange Date, a change in the Company's management under which
Michael J. Anderson is no longer the Company's Senior Vice President and MJA's
Chairman and Chief Executive Officer, (iv) a change in the control of the
Company, and/or (v) breach of the Agreement by the Company which the Company
fails to cure after 30 days' written notice to the Company.  In the event the
employment relationship is terminated by the Company without cause or by
Employee for Changed Circumstances during the term hereof, the Company shall pay
Employee all accrued benefits and unreimbursed expenses owed to Employee that
have accrued but have not been paid as of the Termination Date.  The Company
shall also continue to pay to Employee all salary and benefits hereunder until
May 31, 2001.  Such payments shall be made in accordance with Employee's regular
salary schedule.  Payment of the severance benefits set forth herein shall be
subject to the execution and delivery of a Separation Agreement the terms of
which will reasonably be determined by the parties.  The Company's obligations
pursuant to this Section 11 shall terminate immediately upon any violation of
Section 4 or the taking of any other action by Employee that would have the
effect of declaring the provisions of Section 4 not enforceable.

     12.  Assignment.

          (a) The rights and benefits of Employee under this Agreement, other
than accrued and unpaid amounts due under Section 2 hereof, are personal to him
and shall not be assignable.  Discharge of Employee's undertakings in Sections 3
and 4 hereof shall be an obligation of Employee's executors, administrators, or
other legal representatives or heirs.

          (b) This Agreement may not be assigned by the Company except to an
affiliate of the Company, provided, however, that if the Company shall merge or
effect a share exchange with or into, or sell or otherwise transfer
substantially all its assets to, another corporation, the Company shall assign
its rights hereunder to that corporation and cause such corporation to assume
the Company's obligations under this Agreement.

     14.  Governing Law.  This Agreement shall be interpreted and enforced in

jurisdiction over any dispute relating to Employee's employment by the Company,
its affiliates, and its subsidiaries. Employee consents to the personal
jurisdiction of such courts over Employee with respect to such disputes.

proceeding is brought for the enforcement of this Agreement, or because of an
alleged dispute, breach, or default, the successful or prevailing party shall be
entitled to recover reasonable attorneys' fees, sales and use taxes, court cost,
and all expenses if not taxable court costs (including, without limitation, all
such fees, taxes, costs, and expenses incident to arbitration, appellate,
bankruptcy, and post-judgment proceedings), incurred in that civil action,
arbitration or legal proceeding, in addition to any other relief to which such

paralegal fees, investigative fees, administrative costs, sales and use taxes,
and all other charges billed by the attorney to the prevailing party.

breach or threatened breach by any party of any provision of this Agreement,
then the other parties shall be entitled, in addition to all other rights or
remedies, to an injunction restraining such breach, without being required to
show any actual damage or to post an injunction bond, and/or to a decree for
specific performance of the provisions of this Agreement.

     17.  Severability.  Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid, but if any one
or more 

                                      -11-

of the provisions contained in this Agreement shall be invalid, illegal or
unenforceable in any respect for any reason, the validity, legality and
enforceability for any such provisions in every other respect and of the
remaining provisions of this Agreement shall not be in any way impaired.

     18.  Entire Agreement.  This Agreement contains the entire agreement of the
parties hereto with respect to the subject matter contained herein. There are no
restrictions, promises, covenants, or undertakings, other than those expressly
set forth herein. This Agreement supersedes all prior agreements and
understandings between the parties with respect to such subject matter. This
Agreement may not be changed except by a writing executed by the parties.
