ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS.
          ------------------------------------ 

     On November 10, 1998, Westower Corporation (the "Company") completed the
acquisition of Summit Communications, LLC, a Mississippi limited liability
company ("Summit"), pursuant to an Agreement and Plan of Merger (the "Merger
Agreement") with Summit, the members of Summit (the "Members") and Westower
Summit Acquisition, LLC, a Mississippi limited liability company and a wholly-
owned subsidiary of the Company ("Sub"). Pursuant to the terms of the Merger
Agreement, Sub was merged with and into Summit.  Summit, headquartered in
Jackson, Mississippi, provides construction and related services to providers of
wireless communication services.  The acquisition further extends the Company's
reach into the southeastern and south central states.  The Company intends to
use the assets of Summit as they were used prior to the merger.

     Under the terms of the Merger Agreement, the total consideration paid at
closing by the Company to the Members was $4,400,000 in cash and 200,000 shares
of Westower common stock, par value $.01 per share ("Westower Stock").  The
Members may also receive an earnout of up to 100,000 shares of Westower Stock,
based upon  the number of certain "build-to-suit" towers completed during the
three years immediately following closing.  The merger price was determined by
arms-length negotiations between the parties.  The cash portion of the merger
price was paid out of the Company's cash on hand.

     The foregoing description is qualified in its entirety by reference to the
Merger Agreement, a copy of which is attached hereto as Exhibit 2.1.

<PAGE>
 
     (a) Each Individual Member agrees that for a period of three years
following the Closing Date or eighteen months following from the date of
termination of his employment with Surviving Company for any reason, whether
with or without cause, whichever period is longer, he 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 the business of wireless
telecommunications site development within Canada and/or the United States of
America (a "Business"); (ii) compete with Westower, Surviving Company or their
subsidiaries and affiliates in the operation or development of any Business;
(iii) with the exception of Surviving Company, 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 Surviving Company, or its subsidiaries or affiliates, and any
customer, client, supplier or employee of Surviving Company, or its subsidiaries
or affiliates; or (v) solicit any employee of Surviving Company, or its
subsidiaries or affiliates, to leave their employment with Surviving Company or
its subsidiaries or affiliate, as the case may be, or hire any such employee to
work for a Business.  The Individual Members shall not be entitled to circumvent
the provisions of this Section 7.7 by entering into a relationship with a
Business as a consultant, director, advisor, or otherwise, which has the effect
of competing with Surviving Company, its affiliates or subsidiaries.

     (b) If a judicial determination is made that any of the provisions of
Section 7.7(a) constitute an unreasonable or otherwise unenforceable
restriction, such provisions 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
Section 7.7(a) and to apply the provisions of Section 7.7(a) to the remaining
portion of the territory or the remaining business activities not so severed by
such judicial authority.  The time period during which the prohibitions set
forth in Section 7.7(a) shall apply shall be tolled and suspended during all
violations of Section 7.7(a).

     (c) The Individual Members specifically acknowledge and agree that the
restrictions set forth in this Section are reasonable and necessary to protect
the legitimate interests of Westower and Surviving Company and that Westower and
Sub would not have undertaken the Merger in the absence of such restrictions.
The Individual Members further acknowledge and agree that any violation of the
provisions of this Section 7.7 will result in irreparable injury to Westower and
Surviving Company, that the remedy at law for any violation or threatened
violation of such Section will be inadequate and that in the event of any such
breach, Westower or Surviving Company, in addition to any other remedies or
damages available at law or in equity, shall be entitled to temporary injunctive
relief before 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
the Individual Members against Westower or Surviving Company, whether arising
from this Agreement or otherwise, shall not constitute a defense to the granting
or enforcement of this injunctive relief.  If Westower or Surviving Company is
required to enforce any of its rights under this Agreement, Westower or
Surviving Company shall be entitled 

                                       17
<PAGE>
 
to recover from the Individual Members, as applicable, all reasonable attorneys'
fees, court costs and other expenses incurred by Westower or Surviving Company
in connection with the enforcement of those rights.

      7.8 ELECTION TO CLOSE BOOKS.  The Members agree that promptly following
the Closing they will take whatever steps are necessary to cause the Company to
sign and deliver to the Internal Revenue Service an Election to Close Books Upon
S Corporation Termination and will execute the Consent of the Shareholder to
such election.

      7.9 AUDIT.  The Individual Members will cooperate fully (including
delivery of representation letters in a form customarily required of management)
with independent auditors designated by Westower to allow such auditors to audit
financial statements of Summit for any periods through the Closing Date and
deliver an opinion thereon.

of the Members contained in this Agreement or in any certificate or other
instrument furnished on behalf of Summit or by any of the Members, and

     (b) any and all actions, suits, proceedings, audits, judgments, costs and
legal  and other expenses incident to any of the foregoing or to the enforcement
of this Section 8.1; provided, however, that the Members shall not be liable
                     --------  -------                                      
under this Agreement to the Indemnified Parties for any breach of a
representation or warranty that was not set forth in a notice of claim
(including a contingent claim that sets forth the facts on which a claim may be
made in the future to the extent then known) presented in writing to the

and warranties set forth in 4.17, and (iii) the expiration of the applicable
statute of limitations in the case of Sections 4.2 and 4.6.  Notwithstanding
anything to the contrary herein, the Individual Members shall be liable,
responsible or obligated to indemnify the Indemnified Parties under this Section
8.1 for claims for breach of a representation or warranty only to the extent
that the aggregate amount of Losses exceeds $100,000, and the total liability
and responsibility of the Individual Members under this Section 8.1 for breaches
of representations and warranties shall be limited to the aggregate Merger
Consideration 

                                       18

received by the Members under this Agreement. Payment for indemnification by the
Individual Members may be made in their discretion by cash or the return of
Westower Stock. The value of Westower Stock shall be its average closing price
per share on the American Stock Exchange or other principal market on which it
is traded for the 30 trading days preceding such payment.

      8.2 INDEMNIFICATION BY WESTOWER.  Subject to the consummation of the
Closing, Westower shall indemnify and hold harmless the Members against and in
respect of any and all claims, suits, demands, liabilities, damages, losses,
costs and expenses, arising out of or resulting from any of the following:

          (a) any breach of any representation, warranty or covenant in this
Agreement or in any certificate or other instrument furnished on behalf of
Westower or Sub pursuant to this Agreement, and

          (b) any and all actions, suits, proceedings, audits, judgments, costs
and legal and other expenses incident to any of the foregoing or to the
enforcement of this Section 8.2.

      8.3 INDEMNIFICATION PROCEDURE FOR THIRD-PARTY CLAIMS.  Promptly after the
receipt by any Indemnified Party of notice of any claim or the commencement of
any action or proceeding by any third party, such party will, if a claim with
respect thereto is to be made against any party obligated to provide
indemnification (the "Indemnifying Party") pursuant to Section 8.1, give such
Indemnifying Party written notice of such claim or the commencement of such
action or proceeding. Such Indemnifying Party shall have the right, at its
option and upon posting a bond or other security equal to such claims, to
compromise or defend, at its own expense and by its counsel, any matter
involving the asserted liability of the party seeking such indemnification.
Such notice, and opportunity to defend, shall be a condition precedent to any
liability of the Indemnifying Party under this Article 8. If any Indemnifying
Party shall undertake to compromise or defend any such asserted liability, it
shall promptly notify the party seeking indemnification of its intention to do
so, and the party seeking indemnification agrees to cooperate fully with the
Indemnifying Party and its counsel in the compromise of, or defense against any
such asserted liability.  In any event, the Indemnified Party shall have the
right at its own expense to participate in the defense of such asserted
liability.

                         REGISTRATION RIGHTS AGREEMENT

     This Registration Rights Agreement (this "Agreement") is made as of the
10th day of November, 1998, by and among Westower Corporation, a Washington
corporation (the "Company"), and Mark J. Shapley, Mike A. Jarvis, the Mark J.
Shapley Children's Trust and the Mike A. Jarvis Children's Trust (the
"Shareholders").

                                   BACKGROUND

     On November 10, 1998, the parties to this Agreement entered into an
Agreement and Plan of Merger (the "Merger Agreement"), pursuant to which
Westower Summit Acquisition, LLC, a Mississippi limited liability company and
wholly owned subsidiary of the Company ("Sub"), was merged with and into Summit
Communications, LLC, a Mississippi limited liability company. Capitalized terms
used in this Agreement and not otherwise defined in this Agreement shall have
the meanings given to them in the Merger Agreement.

     Pursuant to the Merger Agreement, the Company issued to the Shareholders
shares of Westower Stock.  As a material term of the Merger Agreement, the
Company has agreed to grant to the Shareholders certain registration rights with
respect to the Registrable Securities.

     Therefore, the parties agree as follows:

1.   REGISTRATION RIGHTS.  The Company covenants and agrees as follows:

     1.1  DEFINITIONS.  For purposes of this Section 1:

          (a) The term "1934 Act" means the Securities Exchange Act of 1934, as
     amended.

          (b) The term "Act" means the Securities Act of 1933, as amended.

          (c) The term "Holder" means any person owning or having the right to
     acquire Registrable Securities or any assignee of Registrable Securities in
     accordance with Section 1.10 of this Agreement.

          (d) The term "register," "registered," and "registration" refer to a
     registration effected by preparing and filing a registration statement in
     compliance with the Act, and the declaration or ordering of effectiveness
     of such registration statement.
<PAGE>
 
          (e) The term "Registrable Securities" means the shares of Westower
     Stock issued under the Merger Agreement and any securities of the Company
     issued or issuable in exchange for or in replacement of, such Westower
     Stock, excluding in all cases, however, (i) any Registrable Securities
     transferred by a Holder 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
     (iii) any Registrable Securities which may be sold in a single 3-month
     period without registration under the Act pursuant to Rule 144 promulgated
     under the Act ("Rule 144").

          (f) The term "SEC" means the Securities and Exchange Commission.

     1.2  DEMAND REGISTRATION

          (a) If the Company receives at any time after the date that is 12
     months after Closing, a written request from the Holders of a majority of
     the Registrable Securities then outstanding (the "Initiating Holders") that
     the Company file a registration statement under the Act covering the
     registration of at least fifty percent (50%) of the Registrable Securities
     then outstanding, then the Company shall:

               (i) within 10 days of the receipt thereof, give written notice of
          such request to all Holders; and

              (ii) use all reasonable efforts to effect as soon as practicable,
          and in any event within 180 days of the receipt of such request, the
          registration under the Act of all Registrable Securities which the
          Holders request to be registered, within 30 days of the mailing of
          such notice by the Company in accordance with Section 2.4. subject to
          the limitations of subsection 1.2(b).

          (b) If the Initiating Holders intend to distribute Registrable
     Securities by means of an underwriting, they shall so advise the Company as
     a part of their request made pursuant to subsection 1.2(a), and the Company
     shall include such information in the written notice referred to in
     subsection 1.2(a).  The underwriter will be selected by the Initiating
     Holders and shall be an underwriter of regional or national standing
     reasonably acceptable to the Company.  In such event, the right of any
     Holder to include Registrable Securities in the registration shall be
     conditioned upon such Holder's participation in the underwriting and the
     inclusion of such Holder's Registrable Securities in the underwriting
     (unless otherwise mutually agreed by a majority in interest of the
     Initiating Holders and such Holder).  All Holders proposing to distribute
     their securities through the underwriting shall (together with the Company
     as provided in subsection 1.4(e)) enter into an underwriting agreement in
     customary form with the underwriter or underwriters selected for such
     underwriting. Notwithstanding any other provision of this Section 1.2, if
     the underwriter advises the Initiating Holders in writing that marketing
     factors require a limitation of the number of shares to be underwritten,
     then the Initiating Holders shall so advise all Holders of 

                                      -2-
<PAGE>
 
     Registrable Securities which would otherwise be underwritten pursuant to
     this subsection, and the number of shares of Registrable Securities that
     may be included in the underwriting shall be allocated among all Holders,
     including the Initiating Holders, in proportion (as nearly as practicable)
     to the amount of Registrable Securities of the Company owned by each
     Holder; provided, however, that the number of shares of Registrable
     Securities to be included in the underwriting shall not be reduced unless
     all other securities are first entirely excluded from the underwriting.

          (c) Notwithstanding the foregoing, if the Company furnishes to
     Initiating Holders a certificate signed by the Chief Executive Officer 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 a registration statement to be filed and it is
     therefore essential to defer the filing of the registration statement, the
     Company shall have the right to defer taking action with respect to the
     filing for a period of not more than 120 days after receipt of the request
     of the Initiating Holders; provided, however, that the Company may not
     utilize this right more than once in any twelve-month period.

          (d) In addition, the Company shall not be obligated to effect, or to
     take any action to effect, any registration pursuant to this Section 1.2:
 
               (i) after the Company has effected two registrations pursuant to
          this Section 1.2 and such registrations have been declared or ordered
          effective; and

               (ii) within twelve months after the effective date of the first
          registration made pursuant to this Section 1.2.

     1.3  PIGGYBACK REGISTRATION.

          If the Company proposes to register (including for this purpose a
registration effected by the Company for shareholders other than the Holders)
any of its stock under the Act in connection with the public offering of such
securities solely for cash (other than a registration on Form S-4 or Form S-8 or
successors thereto or on any other form which does not include substantially the
same information as would be required to be included in a registration statement
covering the sale of the Registrable Securities), the Company shall, at such
time, promptly give each Holder written notice of such registration.  Upon the
written request of each Holder given within 20 days after mailing of such notice
by the Company, the Company shall, subject to the provisions of Section 1.4,
cause to be registered under the Act all of the Registrable Securities that each
such Holder has requested to be registered.  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, or in the event that inclusion of
the Registrable Securities would in the opinion of the managing underwriter for
the offering, impair an offering by the Company or its shareholders for whom the
registration statement is filed, the Company shall have no obligation under this
Section 1.3 to register, or continue with the registration of, the Registrable
Securities.

                                      -3-
<PAGE>
 
     1.4  OBLIGATIONS OF THE COMPANY.  Whenever required under this Section 1 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 with
     respect to such Registrable Securities and use its best efforts to cause
     such registration statement to become effective, and, upon the request of
     the Holders of a majority of the Registrable Securities registered
     thereunder, keep such registration statement effective for a period of up
     to 120 days or until the distribution contemplated in the Registration
     Statement has been completed; provided, however, that the 120-day period
     shall be extended for a period of time equal to the period the Holder is
     prohibited from selling any securities included in such registration
     pursuant to Section 1.11 hereof or the terms of any lockup agreement
     entered into at the request of the Company or an underwriter.

          (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 Registrable Securities owned by them.

          (d) Use its best efforts to register and qualify the securities
     covered by the registration statement under 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 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 managing underwriter of such offering.

          (f) Notify each Holder of Registrable Securities covered by such
     registration statement at any time when a prospectus relating thereto is
     required to be delivered under the Act or 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.

                                      -4-

          (g) Cause all Registrable Securities registered pursuant to this
     Agreement to be listed on each securities exchange on which similar
     securities issued by the Company are then listed.

          (h) Provide a transfer agent and registrar for all Registrable
     Securities registered pursuant to this Agreement and a CUSIP number for all
     such Registrable Securities, in each case not later than the effective date
     of the registration.

          (i) Use its best efforts to furnish, at the request of any Holder
     requesting registration of Registrable Securities pursuant to this
     Agreement, on the date that the Registrable Securities are delivered to the
     underwriters for sale in connection with a registration pursuant to this
     Section 1, if such securities are being sold through underwriters, or, if
     such securities are not being sold through underwriters, on the date that
     the registration statement with respect to such securities becomes
     effective, (i) an opinion, dated such date, of the counsel representing the
     Company, in form and substance as is customarily given to underwriters in
     an underwritten public offering, 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.

     1.5  EXPENSES OF DEMAND REGISTRATION.  All expenses other than underwriting
discounts and commissions incurred in connection with registrations, filings or
qualifications pursuant to Section 1.2, including (without limitation) all
registration, filing and qualification fees, printers' and accounting fees, fees
and disbursements of counsel for the Company (including the reasonable fees and
disbursements of one counsel for the selling Holders) shall be borne by the
Company, provided, however, that the Company shall not be required to pay for
any expenses of any registration proceeding begun pursuant to Section 1.2 if the
registration request is subsequently withdrawn at the request of the Holders of
a majority of the Registrable Securities to be registered (in which case all
participating Holders shall bear such expenses) unless the Holders of a majority
of the Registrable Securities agree to forfeit their right to one demand
registration pursuant to Section 1.2.

     1.6  EXPENSES OF COMPANY REGISTRATION.  The Company shall bear and pay all
expenses incurred in connection with any registration, filing or qualification
of Registrable Securities with respect to the registrations pursuant to Section
1.3 for each Holder, including (without limitation) all registration, filing,
and qualification fees, printers and accounting fees relating or apportionable
thereto and the fees and disbursements of counsel for the Company and the
reasonable fees and disbursements of one counsel for the selling Holders
selected by them, but excluding underwriting discounts and commissions relating
to Registrable Securities.

     1.7  UNDERWRITING REQUIREMENTS.  In connection with any offering involving
an underwriting of shares of the Company's capital stock, the Company shall not
be required under Section 1.3 to include any of the Holders' securities in such
underwriting unless they accept the terms of the underwriting as agreed upon
between the Company and the underwriters selected by it 

                                      -5-
<PAGE>
 
(or by other persons entitled to select the underwriters), and then only in such
quantity as the underwriters determine in their sole discretion will not
jeopardize the success of the offering by the Company. If the total amount of
securities, including Registrable Securities, to be included in such
underwriting exceeds the amount of securities, other than the securities to be
sold by the Company, that the underwriters determine in their sole discretion is
compatible with the success of the offering, then the Company shall be required
to include in the underwriting only that number of Registrable Securities, if
any, which the underwriters determine in their sole discretion will not
jeopardize the success of the offering (the Registrable Securities so included
to be apportioned pro rata among the selling shareholders having piggyback
registration rights according to the total amount of Registrable Securities
entitled to be included therein owned by each selling stockholder or in such
other proportions as shall mutually be agreed to by such selling stockholder).

     1.8  INDEMNIFICATION.  In the event any Registrable Securities are included
in a registration statement:

          (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 1934 Act, against any losses, claims,
     damages, or liabilities (joint or several) to which they may become subject
     under the Act, the 1934 Act or other federal or state law, insofar as such
     losses, claims, damages, or liabilities (or actions in respect thereof)
     arise out of or are based (i) any untrue statement or alleged untrue
     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 or (ii) the omission or alleged
     omission to state therein a material fact required to be stated therein, or
     necessary to make the statements therein not misleading; and the Company
     will pay to each such Holder, underwriter or controlling person, as
     incurred, any legal or other expenses reasonably incurred by them in
     connection with investigating or defending any such loss, claim, damage,
     liability, or action; provided, however, that the indemnity agreement
     contained in this subsection shall not apply to amounts paid in settlement
     of any such loss, claim, damage, liability, or action 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 loss, claim, damage, liability, or action to the extent that
     it arises out of or is based upon written information furnished expressly
     for use in connection with such registration by any such Holder,
     underwriter or controlling person.

          (b) To the extent permitted by law, each selling Holder will indemnify
     and hold harmless the Company, each of its directors, each of its officers
     who has signed the registration statement, each person, if any, who
     controls the Company within the meaning of the Act, any underwriter, any
     other Holder selling securities in such registration statement and any
     controlling person of any such underwriter or other Holder, against any
     losses, claims, damages, or liabilities (joint or several) to which any of
     the foregoing persons may become subject, under the Act, the 1934 Act or
     other federal or state law, insofar as such 

                                      -6-
<PAGE>
 
     losses, claims, damages, or liabilities (or actions in respect thereto)
     arise out of or are based upon written information furnished by such Holder
     expressly for use in connection with such registration; and each such
     Holder will pay, as incurred, any legal or other expenses reasonably
     incurred by any person intended to be indemnified pursuant to this
     subsection, in connection with investigating or defending any such loss,
     claim, damage, liability, or action; provided, however, that the indemnity
     agreement contained in this subsection shall not apply to amounts paid in
     settlement of any such loss, claim, damage, liability or action if such
     settlement is effected without the consent of the Holder, which consent
     shall not be unreasonably withheld; provided, that, in no event shall any
     indemnity under this subsection exceed the gross proceeds from the offering
     received by such Holder.

          (c) Promptly after receipt by an indemnified party under this Section
     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, 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 noticed, to assume the defense thereof with
     counsel mutually satisfactory to the parties; provided, however, than an
     indemnified party (together with all other indemnified parties which may be
     represented without conflict by one counsel) shall have the right to retain
     one separate counsel, with the fees and expenses to be paid by the
     indemnifying party, if 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
     reasonable time of the commencement of any such action, if prejudicial to
     its ability to defend such action, shall relieve such indemnifying party of
     any liability to the indemnified party under this Section, 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.

          (d) If the indemnification provided for in this Section is held by a
     court of competent jurisdiction to be unavailable to an indemnified party
     with respect to any loss, liability, claim, damage, or expense referred to
     therein, then the indemnifying party, in lieu of indemnifying such
     indemnified party hereunder, shall contribute to the amount paid or payable
     by such indemnified party as a result of such loss, liability, claim,
     damage, or expense in such proportion as is appropriate to reflect the
     relative fault of the indemnifying party on the one hand and of the
     indemnified party on the other in connection with the statements or
     omissions that resulted in such loss, liability, claim, damage, or expense
     as well as any other relevant equitable considerations.  The relative fault
     of the indemnifying party and of the indemnified party shall be determined
     by reference to, among other things, whether the untrue or alleged untrue
     statement of a material fact or the omission to state a material fact
     relates to information supplied by the indemnifying party or by the
     indemnified 

                                      -7-
<PAGE>
 
     party and the parties' relative intent, knowledge, access to information,
     and opportunity to correct or prevent such statement or omission.

          (e) Notwithstanding the foregoing, to the extent that the provisions
     on indemnification and contribution contained in the underwriting agreement
     entered into in connection with the underwritten public offering are in
     conflict with the foregoing provisions, the provisions in the underwriting
     agreement shall control.

          (f) The obligations of the Company and Holders under this Section
     shall survive the completion of any offering of Registrable Securities in a
     registration statement under this Agreement.

     1.9  REPORTS UNDER SECURITIES EXCHANGE ACT OF 1934.  With a view to making
available to the Holders the benefits of Rule 144, the Company agrees to use its
reasonable best efforts to:

          (a) make and keep public information available, as those terms are
     understood and defined in Rule 144;

          (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, upon request (i) a written statement by the Company stating
     whether it has complied with the reporting requirements of Rule 144, the
     Act and the 1934 Act, (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 which permits the
     selling of any such securities without registration or pursuant to such
     form.

     1.10  ASSIGNMENT OF REGISTRATION RIGHTS.  The rights to cause the Company
to register Registrable Securities pursuant to this Agreement may be assigned
(but only with all related obligations) by a Holder, provided: (a) the Company
is, within a reasonable 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; (b) such
transferee or assignee agrees in writing to be bound by and subject to the terms
and conditions of this Agreement; (c) 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 the Merger
Agreement; and (d) the Company gives its prior written consent, such consent not
to be unreasonably withheld. The Company agrees that it will consent to
assignments to trusts created by the Shareholders for estate planning purposes.

     1.11  BLACKOUT PERIOD.  If at any time after the effective date of a
registration statement filed hereunder the Company gives to the Shareholders a
notice pursuant to Section 1.4(f) hereof 

                                      -8-
<PAGE>
 
stating that the Company requires the suspension by the Shareholders of the
distribution of any of the Registrable Securities, then the Shareholders shall
cease distributing the Registrable Securities for such period of time (the
"Blackout Period"), not to exceed 120 days from the time notice is sent until
the Company informs the Shareholders that the Blackout Period has been
terminated. Upon notice by the Company to the Shareholders of such
determination, the Shareholders will (a) keep the fact of any such notice
strictly confidential, (b) promptly halt any offer, sale, trading or transfer of
any of the Registrable Securities for the duration of the Blackout Period, and
(c) promptly halt any use, publication, dissemination or distribution of each
prospectus included within the registration statement, and any amendment or
supplement thereto, by it and any of its affiliates for the duration of the
Blackout Period.

     1.12  LOCK-UP.  In connection with any underwritten public offering by the
Company, the Shareholders agree, if requested, to execute a lock-up letter
addressed to the managing underwriter in customary form agreeing not to sell or
otherwise dispose of the Registrable Securities owned by the Shareholders (other
than any that may be included in the offering) for a period not exceeding 180
days.

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.
               ------------------------------------------ 

          (a) 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 (defined below)
and Confidential Information (defined below) of the Company and its affiliates.

          (b) For purposes of this Agreement, a "Trade Secret" is any scientific
or technical information, design, process, procedure, formula or improvement of
the Company or any of its affiliates that is valuable and not generally known to
competitors of the Company and 

                                      -2-
<PAGE>
 
its affiliates. "Confidential Information" is any data or information, other
than Trade Secrets, of the Company or any of its affiliates 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 procedures,
market strategies, internal performance statistics, financial data, confidential
personnel information concerning employees, 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 (1) already in Employee's possession (unless
such information was obtained by Employee from the Company or its affiliates or
was obtained by Employee in the course of Employee's employment by the Company
or its affiliates), (2) received by Employee from a third party with no
restriction on disclosure or (3) required to be disclosed by any applicable law.

          (c) Except as required to perform Employee's duties as an employee,
Employee will not use or disclose any Trade Secrets or Confidential Information
during employment or 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.

          (d) 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 (including all
copies thereof) pertaining to the Company's business, Employee's employment or
the business of the Company or its affiliates. Employee will also leave with the
Company all materials involving any Trade Secrets or Confidential Information.
All such information and materials, whether or not made or developed by
Employee, shall be the sole and exclusive property of the Company or its
affiliates, 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.  Employee hereby covenants and agrees to
               -----------------------                                          
comply with and adhere to the provisions of SECTION 7.7 of the Merger Agreement,
which is incorporated herein by reference with the same effect as if restated
herein in full.

          5.   Specific Enforcement.  Employee specifically acknowledges and
               --------------------                                         
agrees that the restrictions set forth in Section 3 hereof and SECTION 7.7 of
the Merger Agreement as incorporated herein by Section 4 are reasonable and
necessary to protect the legitimate interest of the Company and its affiliates
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 Section 3 hereof or SECTION 7.7 of the Merger Agreement will
result in irreparable injury to the Company or its affiliates, 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 or its
affiliates, in addition to any other remedies or damages available at law or in

                                      -3-
<PAGE>
 
equity, shall be entitled to temporary injunctive relief before 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 or any of its affiliates, 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.   Term of Agreement.  This Agreement shall be effective as of the
               -----------------                                              
Closing Date and shall continue for a term of two (2) years from the Closing
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 ninety
(90) days prior to the end of the then current term.

          7.   Termination Upon Death or Disability of the Employee.  In the
               ----------------------------------------------------         
event the Company ceases its operations (other than pursuant to Section 11

          NOW, THEREFORE, for good and valuable consideration, the receipt and

promises and the mutual covenants and agreements herein set forth, the parties
agree as follows:

          1.   Employment.  As of the Closing Date, the Company hereby employs
               ----------

               ------------

agreed to by the Company and Employee.

          3.   Confidential Information and Trade Secrets.
               ------------------------------------------ 

          (a) 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 (defined below)
and Confidential Information (defined below) of the Company and its affiliates.

          (b) For purposes of this Agreement, a "Trade Secret" is any scientific
or technical information, design, process, procedure, formula or improvement of
the Company or any of its affiliates that is valuable and not generally known to
competitors of the Company and its affiliates.  "Confidential Information" is
any data or information, other than Trade Secrets, of the Company or any of its
affiliates that is important, competitively sensitive, and not generally 

                                      -2-
<PAGE>
 
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 procedures, market strategies, internal performance
statistics, financial data, confidential personnel information concerning
employees, 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 (1) already in Employee's possession (unless such information was
obtained by Employee from the Company or its affiliates or was obtained by
Employee in the course of Employee's employment by the Company or its
affiliates), (2) received by Employee from a third party with no restriction on
disclosure or (3) required to be disclosed by any applicable law.

          (c) Except as required to perform Employee's duties as an employee,
Employee will not use or disclose any Trade Secrets or Confidential Information
during employment or 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.

          (d) 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 (including all
copies thereof) pertaining to the Company's business, Employee's employment or
the business of the Company or its affiliates. Employee will also leave with the
Company all materials involving any Trade Secrets or Confidential Information.
All such information and materials, whether or not made or developed by
Employee, shall be the sole and exclusive property of the Company or its
affiliates, 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.  Employee hereby covenants and agrees to
               -----------------------                                          
comply with and adhere to the provisions of SECTION 7.7 of the Merger Agreement,
which is incorporated herein by reference with the same effect as if restated
herein in full.

          5.   Specific Enforcement.  Employee specifically acknowledges and
               --------------------                                         
agrees that the restrictions set forth in Section 3 hereof and SECTION 7.7 of
the Merger Agreement as incorporated herein by Section 4 are reasonable and
necessary to protect the legitimate interest of the Company and its affiliates
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 Section 3 hereof or SECTION 7.7 of the Merger Agreement will
result in irreparable injury to the Company or its affiliates, 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 or its
affiliates, in addition to any other remedies or damages available at law or in
equity, shall be entitled to temporary injunctive relief before trial from any
court of competent jurisdiction as a matter of course and to permanent
injunctive relief without the necessity of 

                                      -3-
<PAGE>
 
proving actual damages. The existence of any claim or cause of action on the
part of Employee against the Company or any of its affiliates, 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.   Term of Agreement.  This Agreement shall be effective as of the
               -----------------                                              
Closing Date and shall continue for a term of two (2) years from the Closing
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 ninety
(90) days prior to the end of the then current term.

          7.   Termination Upon Death or Disability of the Employee.  In the
               ----------------------------------------------------         
event the Company ceases its operations (other than pursuant to Section 11
below), 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 three (3) 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 unreimbursed expenses owed to Employee or his
estate that have accrued but not been paid as of the date of termination.

          8.   Termination by Employee.  Employee may at any time terminate his
               -----------------------                                         
employment by giving the Company thirty (30) days prior written notice of his
intent to terminate the Agreement, unless the termination is because of Changed
Circumstances as set forth in Section 10.  Upon such termination, Employee shall
have no further obligation to the Company, except as set forth in Sections 3 and
4 hereof, and Employee shall have no further rights or obligations hereunder,
except as set forth in Section 2 hereof for unpaid salary, accrued benefits or
unreimbursed expenses that have accrued but have not been paid as of the date of
termination, unless termination is because of Changed Circumstances, as set
forth in Section 10.

          9.   Termination for Cause.  The Company shall have the right at any
               ---------------------

include any of the following reasons:  Employee's violation of the provisions of
Sections 3 or 4 hereof, gross neglect of duty, conviction under a state or
federal law involving commission of a crime against the Company or any of its
affiliates or a felony, willful failure or refusal to carry out lawful duties or
directions of the Managers of the Company reasonably consistent with the duties
of Employee required by Section 1 hereof, or the willful engaging by the
Employee in gross misconduct materially injurious to the Company or its
affiliates.

          Employee's obligations under Sections 3 and 4 hereof shall survive the
termination of this Agreement pursuant to this Section 9. In the event
Employee's employment hereunder is terminated in accordance with this Section,
the Company shall have no further 

                                      -4-

obligation to make any payments to Employee hereunder except as set forth in

but have not been paid as of the date of termination.  The Company shall also
continue to pay to Employee all salary and benefits hereunder until the
expiration of the term set forth in Section 6.  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 (including a release of all claims against the Company) the
terms of which will reasonably be determined by the parties.  The Company's
obligations pursuant to this Section 10 shall terminate immediately upon any
